12978 Detection and Distribution Pattern of Prevelant Genotypes of Hepatitis C in a Tertiary Care Hospital of Western India
Authors: Upasana Bhumbla
Abstract:
Background: Hepatitis C virus is a major cause of chronic hepatitis, which can further lead to cirrhosis of the liver and hepatocellular carcinoma. Worldwide the burden of Hepatitis C infection has become a serious threat to the human race. Hepatitis C virus (HCV) has population-specific genotypes and provides valuable epidemiological and therapeutic information. Genotyping and assessment of viral load in HCV patients are important for planning the therapeutic strategies. The aim of the study is to study the changing trends of prevalence and genotypic distribution of hepatitis C virus in a tertiary care hospital in Western India. Methods: It is a retrospective study; blood samples were collected and tested for anti HCV antibodies by ELISA in Dept. of Microbiology. In seropositive Hepatitis C patients, quantification of HCV-RNA was done by real-time PCR and in HCV-RNA positive samples, genotyping was conducted. Results: A total of 114 patients who were seropositive for Anti HCV were recruited in the study, out of which 79 (69.29%) were HCV-RNA positive. Out of these positive samples, 54 were further subjected to genotype determination using real-time PCR. Genotype was not detected in 24 samples due to low viral load; 30 samples were positive for genotype. Conclusion: Knowledge of genotype is crucial for the management of HCV infection and prediction of prognosis. Patients infected with HCV genotype 1 and 4 will have to receive Interferon and Ribavirin for 48 weeks. Patients with these genotypes show a poor sustained viral response when tested 24 weeks after completion of therapy. On the contrary, patients infected with HCV genotype 2 and 3 are reported to have a better response to therapy.Keywords: hepatocellular, genotype, ribavarin, seropositive

Authors: Vassilis Argyropoulos, Magda Nikolaraizi, Maria Papazafiri
Abstract:
A growing number of students with disabilities attend institutions of higher education, and according to evidenced-based data, it seems that they face many obstacles regarding their academic access and inclusion. The fact that more and more students decide to actively participate in higher education, on the one hand, empowers and strengthens inclusiveness in tertiary education, but on the other hand, it brings new challenges to their access to scientific content as well as to their interactions with other students and faculty members. For this, accessibility centres have come to the fore in many higher education institutions, in order to respond to the needs of students with disabilities. In this paper, we present a study regarding the peer tutoring program, which is a service delivered by the Accessibility Centre at the University of Thessaly in Greece. Specifically, the current paper aims to describe the experiences of tutees and tutors regarding their relationships developed throughout the peer tutoring program. Twelve tutors and eight tutees with disabilities participated in the study, whose experiences were explored through interviews and were analyzed in a qualitative way. In our study, all tutees and most of the tutors described their relationship as friendly, while a few tutors preferred a more formal relationship. Also, both tutors and tutees described some of the challenges, such as setting limits or arranging an appointment. Finally, peer tutoring programs seem very promising, but in order to be effective, there is a need for training and supporting students regarding their role as well as monitoring the progress of the peer tutoring program, ensuring its smooth operation and success for both tutors and tutees.Keywords: disability, higher education institutions, interviews, peer tutoring, inclusiveness

Authors: Salimah Hasnah, Namratha Radhakrishnan
Abstract:
Communities play a vital role in mobilizing people and resources for the benefit of all. Since time immemorial, communities have been spear heading different activities ranging from disaster management, palliative care, local economic development and many more with laudable success. Urban agriculture is one such activity where communities can prove to make a real difference. Farming activities in cities across different developed countries have proved to have favorable outcomes in the form of increased food security, neighborhood revitalization, health benefits and local economic growth. However, urban agriculture in the developing nations have never been prioritized as an important planning tool to cater to the basic needs of the public. Urban agricultural practices are being carried out in a fragmented fashion without a formal backing. The urban dwellers rely heavily on their far-off rural counterparts for daily food requirements. With the onset of the pandemic and the recurring lockdowns, the significance of geographic proximity and its impact on the availability of food to the public are gradually being realized around the globe. This warrants a need for localized food systems by shortening the distance between production and consumption of food. The significance of communities in realizing these urban farming benefits is explored in this paper. A case-study approach is adopted to understand how different communities have overcome barriers to urban farming in cities. The applicability of these practices is validated against the state of Kerala in India wherein different community centered approaches have been successful in the past. The existing barriers are assessed and way forward to achieve a self-sufficient localized food systems is formulated with the key lessons from the case studies. These recommendations will be helpful to successfully establish and sustain farming activities in urban areas by leveraging the power of communities.Keywords: community-centric, COVID-19, drivers and barriers, local food system, urban agriculture

Authors: Ömer Ateş, Atilla Savaş
Abstract:
Reducers and transmission systems are power and speed transfer tools that have been used for many years in the technology world and in all engineering fields. Since today's transmissions have a threaded tap system, torque interruption occurs during tap change. besides, breakdown and manufacturing costs are high. Another problem is the limited torque and rpm setting in stepped gearbox systems. In this study, a new type of transmission system is designed to solve these problems. This new type of transmission system has been called the Continuously Variable Pulley. The most important feature of the transmission system in the study is that it can be adjusted Revolutions Per Minute-wise and torque-wise at the millimeter (precision) adjustment level. In order to make adjustments at this level, an adjustable pulley with the help of hydraulic piston is designed. The efficiency of the designed transmission system is 97 percent, the efficiency of today's transmissions is in the range of 85-95 percent. examined at the analysis and calculations, it is seen that the designed system gives realistic results and can be compared with today's transmissions and reducers. Therefore, this new type of transmission has been proven to be usable in production areas and the world of technology.Keywords: gearbox, reducer, transmission, torque

Authors: Ammar Alali, Mahmoud Abughaban, William Contreras Otalvora
Abstract:
Optimizing the drilling process for cost and efficiency requires the optimization of the rate of penetration (ROP). ROP is the measurement of the speed at which the wellbore is created, in units of feet per hour. It is the primary indicator of measuring drilling efficiency. Maximization of the ROP can indicate fast and cost-efficient drilling operations; however, high ROPs may induce unintended events, which may lead to nonproductive time (NPT) and higher net costs. The proposed ROP optimization solution is a hybrid, data-driven system that aims to improve the drilling process, maximize the ROP, and minimize NPT. The system consists of two phases: (1) utilizing existing geological and drilling data to train the model prior, and (2) real-time adjustments of the controllable dynamic drilling parameters [weight on bit (WOB), rotary speed (RPM), and pump flow rate (GPM)] that direct influence on the ROP. During the first phase of the system, geological and historical drilling data are aggregated. After, the top-rated wells, as a function of high instance ROP, are distinguished. Those wells are filtered based on NPT incidents, and a cross-plot is generated for the controllable dynamic drilling parameters per ROP value. Subsequently, the parameter values (WOB, GPM, RPM) are calculated as a conditioned mean based on physical distance, following Inverse Distance Weighting (IDW) interpolation methodology. The first phase is concluded by producing a model of drilling best practices from the offset wells, prioritizing the optimum ROP value. This phase is performed before the commencing of drilling. Starting with the model produced in phase one, the second phase runs an automated drill-off test, delivering live adjustments in real-time. Those adjustments are made by directing the driller to deviate two of the controllable parameters (WOB and RPM) by a small percentage (0-5%), following the Constrained Random Search (CRS) methodology. These minor incremental variations will reveal new drilling conditions, not explored before through offset wells. The data is then consolidated into a heat-map, as a function of ROP. A more optimum ROP performance is identified through the heat-map and amended in the model. The validation process involved the selection of a planned well in an onshore oil field with hundreds of offset wells. The first phase model was built by utilizing the data points from the top-performing historical wells (20 wells). The model allows drillers to enhance decision-making by leveraging existing data and blending it with live data in real-time. An empirical relationship between controllable dynamic parameters and ROP was derived using Artificial Neural Networks (ANN). The adjustments resulted in improved ROP efficiency by over 20%, translating to at least 10% saving in drilling costs. The novelty of the proposed system lays is its ability to integrate historical data, calibrate based geological formations, and run real-time global optimization through CRS. Those factors position the system to work for any newly drilled well in a developing field event.Keywords: drilling optimization, geological formations, machine learning, rate of penetration

Authors: Mohammad Bakhshandeh
Abstract:
Structural Health Monitoring (SHM) is a crucial and necessary practice that plays a vital role in ensuring the safety and integrity of critical structures, and in particular, bridges. The continuous monitoring of bridges for signs of damage or degradation through Bridge Health Monitoring (BHM) enables early detection of potential problems, allowing for prompt corrective action to be taken before significant damage occurs. Although all monitoring techniques aim to provide accurate and decisive information regarding the remaining useful life, safety, integrity, and serviceability of bridges, understanding the development and propagation of damage is vital for maintaining uninterrupted bridge operation. Over the years, extensive research has been conducted on BHM methods, and experts in the field have increasingly adopted new methodologies. In this article, we provide a comprehensive exploration of the various BHM approaches, including sensor-based, non-destructive testing (NDT), model-based, and artificial intelligence (AI)-based methods. We also discuss the challenges associated with BHM, including sensor placement and data acquisition, data analysis and interpretation, cost and complexity, and environmental effects, through an extensive review of relevant literature and research studies. Additionally, we examine potential solutions to these challenges and propose future research ideas to address critical gaps in BHM.Keywords: structural health monitoring (SHM), bridge health monitoring (BHM), sensor-based methods, machine-learning algorithms, and model-based techniques, sensor placement, data acquisition, data analysis

Authors: Hebert Sihle Ntuli
Abstract:
Traditional cultural practices mirror or replicate the values and beliefs held by members of the community. Throughout the world, every social grouping has specific traditional practices, some of which are beneficial to all, while others have become harmful to specific group such as women. Like in some African states, these traditional cultural practices are performed in South Africa and are violating women’s rights. Women’s rights are human rights. The South African Constitution is one of the most progressive in the world, and notable includes the Bill of Rights which provides protection of socio-economic and cultural rights. Cultural rights are protected in Section 30 and 31 of the constitution, although such protection is not without limitation. This highly complex interplay and competition between human rights and cultural rights, which are manifested through cultural practices, is the golden thread that traces through this paper. The paper argues that there is conflict and the lack of balance between diverse cultural and legal or constitutional framework which promotes the value of human dignity and equality, especially for women. These practices are reviewed in connection with the South African government laws. This work adopted qualitative research method.Keywords: cultural practices, conflict, South African constitution, laws

Authors: Kumudini Achchi
Abstract:
India, being known for its rich cultural values has given a special place to women who are also been victims of humiliation, torture, and exploitation. The major share of Human Trafficking goes to sex trafficking which is recognised as world’s second most huge social evil. The original form of sex trafficking in India is prostitution with and without religious sanction. Today the situation of such women reached as an issue of human rights where they rights are denied severely. This situation demanded intervention to protect them from the exploitative situation. NGO are the proactive initiatives which offer support to the exploited women in sex trade. To understand the intervention programs of NGOs in South India, a study was conducted covering four states and a union territory considering 32 NGOs based on their preparedness to participate in the research study. Descriptive and diagnostic research design was adopted along with interview schedule as a tool for collecting data. The study reveals that these NGOs believes in the possibility of mainstreaming commercially sexually exploited women and found adopted seven different programs in the process such as rescue, rehabilitation, reintegration, prevention, developmental, advocacy and research. Each area involves different programs to reach and prepare the exploited women towards mainstreamed society which has been discussed in the paper. Implementation of these programs is not an easy task for the organizations rather they are facing hardships in the areas such as social, legal, financial, political which are hindering the successful operations. Rescue, advocacy, and research are the least adopted areas by the NGOs because of lack of support as well as knowledge in the area. Rehabilitation stands as the most adopted area in implementation. The paper further deals with the challenges in the implementation of the programs as well as the remedial measures in social work point of view having Indian cultural background.Keywords: NGOs, commercially sexually exploited women, programmes, South India

Authors: Aruna Bhat
Abstract:
Culture can be placed within the social structure that embodies both the creation of social groups, and the manner in which they interact with each other. As many critics have pointed out, culture in the Postmodern context has often been considered a commodity, and indeed it shares many attributes with commercial products. Popular culture follows many patterns of behavior derived from Economics, from the simple principle of supply and demand, to the creation of marketable demographics which fit certain criterion. This trend is exemplary visible in contemporary fiction, especially in contemporary science fiction; Cyberpunk fiction in particular which is an off shoot of pure science fiction. William Gibson is one such author who in his works portrays such a scenario, and in his The Bridge Trilogy he adds another level of interpretation to this state of affairs, by describing a world that is centered on industrialization of a new kind – that focuses around data in the cyberspace. In this new world, data has become the most important commodity, and man has become nothing but a nodal point in a vast ocean of raw data resulting into commodification of each thing including Culture. This paper will attempt to study the presence of above mentioned elements in William Gibson’s The Bridge Trilogy. The theories applied will be Postmodernism and Cultural studies.Keywords: culture, commodity, cyberpunk, data, postmodern

Authors: Djamel Boussaa
Abstract:
Cultural heritage and tourism have become during the last two decades dynamic areas of development in the world. The idea of heritage is crucial to the critical decision-making process as to how irreplaceable resources are to be utilized by people of the present or conserved for future generations in a fast changing world. In view of the importance of ‘heritage’ to the development of a tourist destination the emphasis on developing appropriate adaptive reuse strategies cannot be overemphasized. In October 1999, the 12th general assembly of the ICOMOS in Mexico stated, that in the context of sustainable development, two interrelated issues need urgent attention, cultural tourism and historic towns and cities. These two issues underscore the fact that historic resources are non-renewable, belonging to all of humanity. Without adequate adaptive reuse actions to ensure a sustainable future for these historic resources, may lead to their complete vanishing. The growth of tourism and its role in dispersing cultural heritage to everyone is developing rapidly. According to the World Tourism Organization, natural and cultural heritage resources are and will remain motivating factors for travel in the foreseeable future. According to the experts, people choose travel destinations where they can learn about traditional and distinct cultures in their historic context. The Qatar rich urban heritage is now being recognized as a valuable resource for future development. This paper discusses the role of cultural heritage and tourism in regenerating Souk Waqif, and consequently the city of Doha. Therefore, in order to use cultural heritage wisely, it will be necessary to position heritage as an essential element of sustainable development, giving particular attention to cultural heritage and tourism. The research methodology is based on an empirical survey of the situation, based on several visits, meetings and interviews with the local heritage players. The rehabilitation project initiated since 2004 will be examined and assessed. Therefore, there is potential to assess the situation and propose directions for a sustainable future to this historic landmark. Conservation for the sake of conservation appears to be an outdated concept. Many irreplaceable natural and cultural sites are being compromised because local authorities are not giving economic consideration to the value of rehabilitating such sites. The question to be raised here is 'How can cultural heritage be used wisely for tourism without compromising its social sustainability within the emerging global world?'Keywords: cultural heritage, tourism, regeneration, economy, social sustainability
Procedia PDF Downloads 42112968 Models Comparison for Solar Radiation
Authors: Djelloul Benatiallah
Abstract:
Due to the current high consumption and recent industry growth, the depletion of fossil and natural energy supplies like oil, gas, and uranium is declining. Due to pollution and climate change, there needs to be a swift switch to renewable energy sources. Research on renewable energy is being done to meet energy needs. Solar energy is one of the renewable resources that can currently meet all of the world's energy needs. In most parts of the world, solar energy is a free and unlimited resource that can be used in a variety of ways, including photovoltaic systems for the generation of electricity and thermal systems for the generation of heatfor the residential sector's production of hot water. In this article, we'll conduct a comparison. The first step entails identifying the two empirical models that will enable us to estimate the daily irradiations on a horizontal plane. On the other hand, we compare it using the data obtained from measurements made at the Adrar site over the four distinct seasons. The model 2 provides a better estimate of the global solar components, with an absolute mean error of less than 7% and a correlation coefficient of more than 0.95, as well as a relative coefficient of the bias error that is less than 6% in absolute value and a relative RMSE that is less than 10%, according to a comparison of the results obtained by simulating the two models.Keywords: solar radiation, renewable energy, fossil, photovoltaic systems

Authors: Renukha Devi Anandan
Abstract:
Charles Forsman’s The End of The Fxxxing World, I Am Not Okay With This, and Slasher invariably deals with existential themes. They reflect the perplexed situation of the characters torn between the search for existence and the constraints of human conditions that impede them from such realization, ensuing a dilemma deeply-rooted in absurdity and alienation. These characters are social misfits who fail to fashion their existence and develop harmoniously. Therefore, the present paper adopts an Existential approach to examine the vignettes of alienation and absurdity vis-à-vis the characters’ speech, actions, and thoughts. Furthermore, this paper explores the role of death either as a self-destructive behavior or the eternal freedom of man in graphic novels. Findings portrayed how the characters’ absurd existence surrounded by the void, would eventually develop into death. Finally, the study revealed that Forsman’s distinctive serial illustration not only unveiled the predicaments of the characters through their hard-boiled smokescreens in the 21st-century social paradigm but also established graphic novels as part and parcel of a literary genre.Keywords: existentialism, absurdity, alienation, death, self-destruction, eternal freedom

Authors: Utsha Barua Joy
Abstract:
Buddhism has been playing as a cultural mediator in the world Asia. Buddhism spread as a living spiritual tradition and philosophy and spread mostly as a part of the cultural heritage. Culture and religion concern and deal with some similar human issues in terms of the concept of values. This article mainly focuses on some pertinent issues. The Buddha created a revolutionary awareness in the history of mankind by giving equal status to all. With equality, man gets social, mental, economic, and political freedom. This article moreover discusses the concept of morality, educational system, and finally, missionary services. After the first rainy retreat, Buddha asked the monks to go from place to place and spread the Dharma for the welfare of mankind. Since then, all the monks took part in missionary work. Emperor Asoka’s missionary steps are the brightened example in the history of Buddhism. The goal of this article is to provide to the wise readers with a delineation of reference on how equality, morality, education system, and missionary services through Buddhism rendered great contribution to the cultural arena around the globe.Keywords: equality, morality, educational system, missionary works
Procedia PDF Downloads 20812965 Conceptualizing Clashing Values in the Field of Media Ethics
Authors: Saadia Izzeldin Malik
Abstract:
Lack of ethics is the crisis of the 21-century. Today’s global world is filled with economic, political, environmental, media/communication, and social crises that all generated by the eroding fabric of ethics and moral values that guide human’s decisions in all aspects of live. Our global world is guided by liberal western democratic principles and liberal capitalist economic principles that define and reinforce each other. In economic terms, capitalism has turned world economic systems into one market place of ideas and products controlled by big multinational corporations that not only determine the conditions and terms of commodity production and commodity exchange between countries, but also transform the political economy of media systems around the globe. The citizen (read the consumer) today is the target of persuasion by all types of media at a time when her/his interests should be, ethically and in principle, the basic significant factor in the selection of media content. It is very important in this juncture of clashing media values –professional and commercial- and wide spread ethical lapses of media organizations and media professionals to think of a perspective to theorize these conflicting values within a broader framework of media ethics. Thus, the aim of this paper is to, epistemologically, bring to the center a perspective on media ethics as a basis for reconciliation of clashing values of the media. The paper focuses on conflicting ethical values in current media debate; namely ownership of media vs. press freedom, individual right for privacy vs. public right to know, and global western consumerism values vs. media values. The paper concludes that a framework to reconcile conflicting values of media ethics should focus on the “individual” journalist and his/her moral development as well as focus on maintaining ethical principles of the media as an institution with a primary social responsibility for the “public” it serves.Keywords: ethics, media, journalism, social responsibility, conflicting values, global
Procedia PDF Downloads 49212964 Potentials, Challenges And Prospects Of Halal Tourism Development In Ethiopia
Authors: Mohammed Jemal Ahmed
Abstract:
Some anti-Islam attributes, such as alcoholism and voyeurism, have become de facto manifestations of the tourism sector. This eventually causes a paradoxical relationship between tourism and Islam. Hence, on the one hand, Islam inherently encourages Muslims to engage in tourism, the interest of Muslims to engage in tourism is steadily increasing. On the other hand, haram activities and products that are not allowed to Muslims as per the Islamic law and doctrine have surrounded tourism. Therefore, halal tourism has emerged as the best mediator to reconcile the conflicts between secular interests and religious values. Recent studies have confirmed that halal tourism is an emerging cultural phenomenon and secular rather than religious. The central aim of halal tourism is to have delighted customers irrespective of their religious and cultural backgrounds while promoting environmental conservation and social coexistence. This study appraises halal tourism development in Ethiopia from commercial, socio-cultural and diplomatic perspectives. Employing qualitative methodologies, the study, firstly, tried to clarify the existing terminological ambiguities between halal tourism and Islamic tourism and redefine both concepts. Then, it assessed perceptions of local communities and stakeholders towards halal tourism and identified halal tourism resources of Ethiopia. Accordingly, five clusters of halal visitor attractions and five potential halal tourism routes were identified and proposed. Furthermore, the comparative advantages of Ethiopia in terms of halal tourism development and potential barriers to halal tourism development in the country were rigorously appraised. The findings of this study reveal that halal tourism could inject hard currency into the national economy and create job opportunities for the locals. It could also support the mainstream tourism industry through product diversification and curving seasonality. Moreover, socially, halal tourism reinforces interreligious cohesion, relationship and coextensive in multi-religious, multicultural and multiethnic Ethiopia. Politically, it strengthens Ethiopia's foreign diplomatic relationship with the Islamic world and its near and distant neighbor Muslim Countries.Keywords: halal-conscious travelers, halal tourism, Islamic tourism, tourism resources

Authors: Smiso Buthelezi, Petros Dlamini, Dennis Ocholla
Abstract:
The study assesses the University of Zululand's practices for documenting, sharing, and accessing indigenous knowledge. Two research objectives guided it: to determine how indigenous knowledge (IK) is developed at the University of Zululand and how indigenous knowledge (IK) is documented at the University of Zululand. The study adopted both interpretive and positivist research paradigms. Ultimately, qualitative and quantitative research methods were used. The qualitative research approach collected data from academic and non-academic staff members. Interviews were conducted with 18 academic staff members and 5 with support staff members. The quantitative research approach was used to collect data from indigenous knowledge (IK) theses and dissertations from the University of Zululand Institutional Repository between 2009-2019. The study results revealed that many departments across the University of Zululand were involved in creating indigenous knowledge (IK)-related content. The department of African Languages was noted to be more involved in creating IK-related content. Moreover, the documentation of the content related to indigenous knowledge (IK) at the University of Zululand is done frequently but is not readily known. It was found that the creation and documentation of indigenous knowledge by different departments faced several challenges. The common challenges are a lack of interest among indigenous knowledge (IK) owners in sharing their knowledge, the local language as a barrier, and a shortage of proper tools for recording and capturing indigenous knowledge (IK). One of the study recommendations is the need for an indigenous knowledge systems (IKS) policy to be in place at the University of Zululand.Keywords: knowledge creation, SECI model, information and communication technology., indigenous knowledge

Authors: Youmen Chaaban
Abstract:
The study examined the influence of a situated professional development program (PD) aimed at enhancing English language teachers’ knowledge and skills and improving their instructional practices. The PD model under examination was developed upon sound theoretical underpinnings, taking into consideration research-based principles of effective PD. However, the implementation of the PD model within several school contexts required further investigation from the perspectives of the teachers, who were receiving the PD activities, and the instructional coaches, who were providing them. The paper, thus, presents the results of a qualitative study examining the perceptions of seventeen English language teachers and nineteen instructional coaches about the strengths of the PD program, the challenges they faced in the implementation of the program, and their suggestions for the improvement of the program’s implementation and outcomes. Comparisons were further made between the two groups of participants to uncover agreements and contradictions in their perceptions. Data were collected from the teachers through in-depth interviews and observations, while the data collected from the instructional coaches were open-ended surveys followed by focus group interviews. The findings of the study confirm the necessity of structuring PD activities around sound theoretical underpinnings. However, practical considerations specific to the contexts where the PD activities take place should be considered when evaluating the PD’s effectiveness. Finally, the study provides several recommendations for maximizing the influence of the PD program on teachers’ practices and beliefs.Keywords: English language teachers, situated professional development, teacher beliefs, teacher practices

Authors: Tsetsegmaa A., Bayarsuren B., Altantsetseg Ts.
Abstract:
To make the best decision on reducing harmful emissions from buses, we need to have a clear understanding of the current state of their actual emissions. The emissions from city buses running on high sulfur fuel, particularly particulate matter (PM) and nitrogen oxides (NOx) from the exhaust gases of conventional diesel engines, have been studied and measured with and without diesel particulate filter (DPF) in Ulaanbaatar city. The study was conducted by using the PEMS (Portable Emissions Measurement System) and gravimetric method in real traffic conditions. The obtained data were used to determine the actual emission rates and to evaluate the effectiveness of the selected particulate filters. Actual road and daily PM emissions from city buses were determined during the warm and cold seasons. A bus with an average daily mileage of 242 km was found to emit 166.155 g of PM into the city's atmosphere on average per day, with 141.3 g in summer and 175.8 g in winter. The actual PM of the city bus is 0.6866 g/km. The concentration of NOx in the exhaust gas averages 1410.94 ppm. The use of DPF reduced the exhaust gas opacity of 24 buses by an average of 97% and filtered a total of 340.4 kg of soot from these buses over a period of six months. Retrofitting an old conventional diesel engine with cassette-type silicon carbide (SiC) DPF, despite the laboriousness of cleaning, can significantly reduce particulate matter emissions. Innovation: First comprehensive road PM and NOx emission dataset and actual road emissions from public buses have been identified. PM and NOx mathematical model equations have been estimated as a function of the bus technical speed and engine revolution with and without DPF.Keywords: conventional diesel, silicon carbide, real-time onboard measurements, particulate matter, diesel retrofit, fuel sulphur

Authors: Edwina Owusu Panin, Kwame Baah Owusu Panin
Abstract:
This abstract intends to demonstrate multiple strategies of autism management in Ghana by exploring the possibilities. The advantages of adopting creative art forms as a therapeutic method. Autism is a developmental disorder that includes social interaction, communication, and repetitive behaviours. In Ghana, as in many other countries, there is a rising demand for effective intervention and support for people with autism and their families. Creative arts such as music, dance, drama and visual arts have shown promise in promoting communication, social interaction and inclusion of people with autism. These art forms provide alternative channels for self-expression and can be powerful tools for autistic people to interact with the world, their friends and families around them. Creative art forms interventions have been found to improve social skills, improve emotion regulation, promote creativity and increase self-confidence in people with autism. This study examines existing programs and interventions in Ghana involving creative art forms for people with autism through a comparative analysis. It explores the different approaches, methods and results of these interventions. By comparing and evaluating these programs, the study aims to identify best practices, challenges and areas for development in managing autism through the creative arts in Ghana. Although many schools and rehabilitation centres employ various forms in therapeutic approaches for autism. There is no comparative analysis of which type of autism and which creative art forms is suitable. The results of this study will contribute to the development of evidence-based practices for the management of autism in Ghana. It provides valuable information about the effectiveness of creative arts interventions and helps inform policy makers, educators, therapists and other stakeholders involved in autism support. Ultimately, the goal is to improve the well-being and quality of life of people with autism in Ghana and their families by promoting inclusive and accessible interventions that harness the power of creative art forms.Keywords: autism, therapeutic, creative art, art form

Authors: Qirat Naz, Abasiokpon Udoakah
Abstract:
In developed countries, global migration is diversifying. The minority ethnic population, including refugees and asylum seekers who, fled their home countries due to war, terrorism, oppression, or natural disasters, and returning home is dangerous for them. They need sanctuary and peaceful environment in host countries. They begin the process of acculturation, in which a person adopts the social mores and behavioral patterns of the dominant culture, yet they still have unique multicultural needs that the dominant society fails to address. The aim of this research is to provide a holistic understanding of the living experiences of a minority population, particularly migrants, including asylum seekers and refugees, in the health and social care system of South Wales. The purpose of this study is to investigate three research objectives: the multicultural health care needs of minorities, as well as the barriers to seeking health and social care facilities. There are Welsh policies for promoting cultural competence in the health and social care sectors; this research will explore the implications and impact of these policies on the target population. This research study will be conducted using qualitative research methods, tools, and techniques. This research is an inductive approach to coming up with a grounded theory. The sample will be divided into two groups: migrants and professionals providing any kind of services to migrants; each group will contain 30 participants. Interpretive phenomenological analysis would be utilized during the process of coding and developing the main themes of this research. The positionality of the researcher would be minimized by unloaded and open-ended questions, researcher’s work experience in research, continuous evaluation of her positionality, daily base reflection of fieldwork and seeking the help of male and female gatekeepers. The research findings would be based on emic perspective, and by documenting the emic perspective of minorities, this research will contribute to the knowledge of appropriate channels, including organizations, academics, and policymakers, to discover possible solutions and coping mechanisms to deal with the challenges and meet the multicultural demands of minorities.

Authors: Syed Ahsan, Saleh Alshomrani, Ishtiaq Rasool, Ali Hassan
Abstract:
In this oral presentation, we will provide an overview of the technical and semantic architecture of a desert border security and critical infrastructure protection security system. Modern border security systems are designed to reduce the dependability and intrusion of human operators. To achieve this, different types of sensors are use along with video surveillance technologies. Application of these technologies in a harsh desert environment of Saudi Arabia poses unique challenges. Environmental and geographical factors including high temperatures, desert storms, temperature variations and remoteness adversely affect the reliability of surveillance systems. To successfully implement a reliable, effective system in a harsh desert environment, the following must be achieved: i) Selection of technology including sensors, video cameras, and communication infrastructure that suit desert environments. ii) Reduced power consumption and efficient usage of equipment to increase the battery life of the equipment. iii) A reliable and robust communication network with efficient usage of bandwidth. Also, to reduce the expert bottleneck, an ontology-based intelligent information systems needs to be developed. Domain knowledge unique and peculiar to Saudi Arabia needs to be formalized to develop an expert system that can detect abnormal activities and any intrusion.Keywords: border security, sensors, abnormal activity detection, ontologies

Authors: Pachawo Bisani, Goodall Nyirenda
Abstract:
The Malawi National Antiretroviral Therapy (NART) Electronic Medical Record (EMR) system was designed and developed with guidance from the Ministry of Health through the Department of HIV and AIDS (DHA) with the aim of supporting the management of HIV patient data and reporting in high prevalence ART clinics. As of 2021, the system has been scaled up to over 206 facilities across the country. The system is integrated with the clinical decision support system (CDSS) to assist healthcare providers in making a decision about an individual patient at a particular point in time. Despite NART EMR undergoing several evaluations and assessments, little has been done to evaluate the clinical decision support system in the NART EMR system. Hence, the study aimed to evaluate the use of CDSS in the NART EMR system in Malawi. The study adopted a mixed-method approach, and data was collected through interviews, observations, and questionnaires. The study has revealed that the CDSS tools were integrated into the ART clinic workflow, making it easy for the user to use it. The study has also revealed challenges in system reliability and information accuracy. Despite the challenges, the study further revealed that the system is effective and efficient, and overall, users are satisfied with the system. The study recommends that the implementers focus more on the logic behind the clinical decision-support intervention in order to address some of the concerns and enhance the accuracy of the information supplied. The study further suggests consulting the system's actual users throughout implementation.Keywords: clinical decision support system, electronic medical record system, usability, antiretroviral therapy

Authors: Dinesh Khanduja, Sahib Sartaj Singh
Abstract:
In India, among the start ups, many new ventures fail and for the few that survive and grow, there are always numerous problems. In order to make these surviving units productive and cost effective-in today’s competitive environment, the traditional ways of supporting small enterprises and the related programs of governmental assistance need to be significantly transformed. In this context, ‘Business Incubation’ is emerging as one of the most innovative instruments to support small enterprise creation and development all over the world. Incubators, by providing on the-spot diagnosis and treatment of business problems, dramatically lower the early stage failure rate. In Europe, US and countries like China, Singapore, Thailand etc., the exceptionally fast growth of business incubators has baffled even the researchers. In this direction in India, following on the world pattern, several initiatives have been taken over the last decade to encourage the concept of business incubation. Besides profiling the existing ‘Business Incubators’ in India, the paper dwells upon a case study of SMEs in state of Punjab for exploring the relevance of business incubation for enhancing their productive capacity.Keywords: business incubation, Technology Business Incubator (TBI), Rural Business Hub (RBH), entrepreneurship, Business Development Services (BDS), technology management
Procedia PDF Downloads 50512954 Design of an Improved Distributed Framework for Intrusion Detection System Based on Artificial Immune System and Neural Network
Authors: Yulin Rao, Zhixuan Li, Burra Venkata Durga Kumar
Abstract:
Intrusion detection refers to monitoring the actions of internal and external intruders on the system and detecting the behaviours that violate security policies in real-time. In intrusion detection, there has been much discussion about the application of neural network technology and artificial immune system (AIS). However, many solutions use static methods (signature-based and stateful protocol analysis) or centralized intrusion detection systems (CIDS), which are unsuitable for real-time intrusion detection systems that need to process large amounts of data and detect unknown intrusions. This article proposes a framework for a distributed intrusion detection system (DIDS) with multi-agents based on the concept of AIS and neural network technology to detect anomalies and intrusions. In this framework, multiple agents are assigned to each host and work together, improving the system's detection efficiency and robustness. The trainer agent in the central server of the framework uses the artificial neural network (ANN) rather than the negative selection algorithm of AIS to generate mature detectors. Mature detectors can distinguish between self-files and non-self-files after learning. Our analyzer agents use genetic algorithms to generate memory cell detectors. This kind of detector will effectively reduce false positive and false negative errors and act quickly on known intrusions.Keywords: artificial immune system, distributed artificial intelligence, multi-agent, intrusion detection system, neural network

Authors: Elham Rajabian
Abstract:
The ascent of cybersecurity incidents is a rising threat to most organisations in general, while the impact of the incidents is unique to each of the organizations. It is a need for behavioural sciences to concentrate on employees’ behaviour in order to prepare key security mitigation opinions versus cybersecurity incidents. There are noticeable differences among users of a computer system in terms of complying with security behaviours. We can discuss the people's differences under several subjects such as delaying tactics on something that must be done, the tendency to act without thinking, future thinking about unexpected implications of present-day issues, and risk-taking behaviours in security policies compliance. In this article, we introduce high-profile cyber-attacks and their impacts on weakening cyber resiliency in organizations. We also give attention to human errors that influence network security. Human errors are discussed as a part of psychological matters to enhance compliance with the security policies. The organizational challenges are studied in order to shape a sustainable cyber risks management approach in the related work section. Insiders’ behaviours are viewed as a cyber security gap to draw proper cyber resiliency in section 3. We carry out the best cybersecurity practices by discussing four CIS challenges in section 4. In this regard, we provide a guideline and metrics to measure cyber resilience in organizations in section 5. In the end, we give some recommendations in order to build a cybersecurity culture based on individual behaviours.Keywords: cyber resilience, human factors, cybersecurity behavior, attitude, usability, security culture

Authors: H. Jalahi, A. Yazdanpanah Nozari
Abstract:
Background and Purpose: Assessment of learners’ performance is an important factors in teaching-learning process. When a factor is sensitive and has high influence on life, their assessment should be done precisely. Thinking dispositions are very important factors in medical education because of its specific condition. In this study a model is designed for fostering thinking dispositions of learners in which authentic assessment is an important element. Materials and Methods: Objective based research is developmental, and such a model was not designed for curricula. Data collection and comparing approaches about assessment and analyzing current assessments offered applied proposals. Results: Based on research findings, the current assessments are response-based, that is students instead of product of response, only offers the specific response which the teachers expects; but authentic assessment is a form of assessment in which students are asked to perform real-word tasks that demonstrate meaningful application of essential knowledge and skills. Conclusion: Because of the difficulties and unexpected problems in life and individuals needs to lifelong learning and conditions in medical course that require decision making in specific times, we must pay attention to reach thinking dispositions and it should be included in curriculum. Authentic assessment as an important aspect of curriculum can help fostering thinking dispositions of learners. Using this kind of assessments which focus on application of information and skills to solve real-word tasks have more important role in medical courses.Keywords: assessment, authentic, medical courses, developmental

Authors: Roberta Facchinetti, Sara Corrizzato, Silvia Cavalieri
Abstract:
Increasing interconnection between data digitalization and linguistic investigation has given rise to unprecedented potentialities and challenges for corpus linguists, who need to master IT tools for data analysis and text processing, as well as to develop techniques for efficient and reliable annotation in specific mark-up languages that encode documents in a format that is both human and machine-readable. In the present paper, the challenges emerging from the compilation of a linguistic corpus will be taken into consideration, focusing on the English language in particular. To do so, the case study of the InterDiplo corpus will be illustrated. The corpus, currently under development at the University of Verona (Italy), represents a novelty in terms both of the data included and of the tag set used for its annotation. The corpus covers media interviews and debates with diplomats and international operators conversing in English with journalists who do not share the same lingua-cultural background as their interviewees. To date, this appears to be the first tagged corpus of international institutional spoken discourse and will be an important database not only for linguists interested in corpus analysis but also for experts operating in international relations. In the present paper, special attention will be dedicated to the structural mark-up, parts of speech annotation, and tagging of discursive traits, that are the innovational parts of the project being the result of a thorough study to find the best solution to suit the analytical needs of the data. Several aspects will be addressed, with special attention to the tagging of the speakers’ identity, the communicative events, and anthropophagic. Prominence will be given to the annotation of question/answer exchanges to investigate the interlocutors’ choices and how such choices impact communication. Indeed, the automated identification of questions, in relation to the expected answers, is functional to understand how interviewers elicit information as well as how interviewees provide their answers to fulfill their respective communicative aims. A detailed description of the aforementioned elements will be given using the InterDiplo-Covid19 pilot corpus. The data yielded by our preliminary analysis of the data will highlight the viable solutions found in the construction of the corpus in terms of XML conversion, metadata definition, tagging system, and discursive-pragmatic annotation to be included via Oxygen.Keywords: spoken corpus, diplomats’ interviews, tagging system, discursive-pragmatic annotation, english linguistics

Authors: Nino Paresashvili, Nino Abesadze
Abstract:
The modern world faces huge challenges. Globalization changed the socio-economic conditions of many countries. The current processes in the global environment have a different impact on countries with different cultures. However, an alleviation of poverty and improvement of living conditions is still the basic challenge for the majority of countries, because much of the population still lives under the official threshold of poverty. It is very important to stimulate youth employment. In order to prepare young people for the labour market, it is essential to provide them with the appropriate professional skills and knowledge. It is necessary to plan efficient activities for decreasing an unemployment rate and for developing the perfect mechanisms for regulation of a labour market. Such planning requires thorough study and analysis of existing reality, as well as development of corresponding mechanisms. Statistical analysis of unemployment is one of the main platforms for regulation of the labour market key mechanisms. The corresponding statistical methods should be used in the study process. Such methods are observation, gathering, grouping, and calculation of the generalized indicators. Unemployment is one of the most severe socioeconomic problems in Georgia. According to the past as well as the current statistics, unemployment rates always have been the most problematic issue to resolve for policy makers. Analytical works towards to the above-mentioned problem will be the basis for the next sustainable steps to solve the main problem. The results of the study showed that the choice of young people is not often due to their inclinations, their interests and the labour market demand. That is why the wrong professional orientation of young people in most cases leads to their unemployment. At the same time, it was shown that there are a number of professions in the labour market with a high demand because of the deficit the appropriate specialties. To achieve healthy competitiveness in youth employment, it is necessary to formulate regional employment programs with taking into account the regional infrastructure specifications.Keywords: unemployment, analysis, methods, tendencies, regulation mechanisms
