596 Design of Cylindrical Crawler Robot Inspired by Amoeba Locomotion
Authors: Jun-ya Nagase
Abstract:
Recently, the need of colonoscopy is increasing because of the rise of colonic disorder including cancer of the colon. However, current colonoscopy depends on doctor's skill strongly. Therefore, a large intestine endoscope that does not depend on the techniques of a doctor with high safety is required. In this research, we aim at development a novel large intestine endoscope that can realize safe insertion without specific techniques. A wheel movement type robot, a snake-like robot and an earthworm-like robot are all described in the relevant literature as endoscope robots that are currently studied. Among them, the tracked crawler robot can travel by traversing uneven ground flexibly with a crawler belt attached firmly to the ground surface. Although conventional crawler robots have high efficiency and/or high ground-covering ability, they require a comparatively large space to move. In this study, a small cylindrical crawler robot inspired by amoeba locomotion, which does not need large space to move and which has high ground-covering ability, is proposed. In addition, we developed a prototype of the large intestine endoscope using the proposed crawler mechanism. Experiments have demonstrated smooth operation and a forward movement of the robot by application of voltage to the motor. This paper reports the structure, drive mechanism, prototype, and experimental evaluation.Keywords: tracked-crawler, endoscopic robot, narrow path, amoeba locomotion.

Authors: Prih Bukhari
Abstract:
The purpose of the proposed paper is to determine if the perception of online advertisement formed due to attitude and belief vary among two different countries or not. Specifically, it seeks to find out how people from China and Pakistan perceive online advertisement. Public attitude and belief towards advertising have been a focus of attention to explore a path to a better strategy of advertising. The ‘belief’ factor was analyzed through 4 items, i.e., product information, entertainment, and increase in economy’ whereas, the ‘attitude’ factor was analyzed thorough questions based on 4 items, i.e. ‘overall, I consider online advertising a good thing’; 'overall, I like online advertising’; ‘'I consider online advertising very essential’; and 'I would describe my overall attitude toward online advertising very favorably’. As such, it provides theoretical basis to explain similarities and differences of beliefs and attitude towards advertising across the two countries. Given its mixed method approach, both quantitative and qualitative method is used to carry out research. A questionnaire-based survey and focus group interviews were conducted. The sample size was of 500 participants. For analysis survey copies were then collected from which 497 were received whereas focus group interviews were collected from both nations. The findings showed that the belief factor among both countries had no significant relation with the perception of online advertisement. However, the attitude had a significant relation with the perception about online advertisement. Also it was observed that despite of different backgrounds, perception about online advertisement based on beliefs and attitude were found largely to be similar. Implications and future studies are provided.Keywords: attitude, belief, online advertisement, perception

Authors: Rahayu Azkiya
Abstract:
Career guidance is an integral part of education that aims to help students understand their interests, talents, and potential and provide direction in choosing an appropriate career path. Approximately 76 million people are working out of 17 million people with disabilities in 2022, and this number has become a focal point as career guidance is crucial among people with special needs. Therefore, this study explores how the career guidance program is implemented and what challenges are faced by teachers. This study employs a qualitative case study in one of the senior high schools for special needs (SMLB) in Depok, Indonesia. Meanwhile, the data analysis was done through thematic analysis. Data has been obtained through the interviews of two teachers who focused on the physically impaired and deaf. The results of this study show that (1) the school has implemented career guidance well, the students were selected in the first year to look for their talents and interests, and for the second and third years, students are trained to master their abilities. (2) There are still many challenges teachers face in implementing career guidance programs, such as a need for more human resources for both students and teachers, high curriculum demands, and simple facilities that hinder student progress. Therefore, this research shows that every child is unique, so schools must meet the standards of student needs and re-evaluate the various challenges that teachers and students still face. This research is expected to serve as an analysis material for the government's policy towards special needs schools in Indonesia.Keywords: Students with Special Needs, Career Guidance Program, Implementation, Challenges

Authors: Hyun-Soo Seol, In-Gun Kim, Hyun Seok Hong, Dong-Woo Kang, Ju Lee
Abstract:
Rotor of Spoke-Type PMSM is divided into permanent magnet and rotor core. Moreover, rotor core is composed of pole-piece, Bridge and rib. Piece between the permanent magnet N and S poles is pole-piece. Bridge and rib hold pole-piece. In the case of pole-piece and bridge, it is essential structure of Spoke-Type PMSM. However, Rib can be selected by the designer depending on the operating conditions and constraints. If rib is present in the rotor, rib which acts in the leak path generates a leakage flux. Although the leakage flux reduces the torque in low speed, it expands speed range in high speed. So, there is a relationship of trade off. Viewed from the standpoint of permanent magnet demagnetization, since the magnetic flux by the stator winding leaks to the rib, it is an advantage. In addition, rib affects the safety factor of the rotor. For application required high speed operation, since the securing the safety factor of the rotor is important, rib structure is advantageous. On the other hand, in the case of the application that does not require high speed operation, it is desirable to increase the output power by designing without rib. In this paper, Effects on rib structure is analyzed in detail and this paper provides designer with information about rotor design of spoke-type PMSM according to rib structure.Keywords: spoke-Type PMSM, rotor shape, rib, operation range

Authors: Dragana Bubulj
Abstract:
The Former Republic of Yugoslavia was a sort of protective umbrella, a unique concept of gathering different ethnical, cultural, and religious identities, as well as diverse intersections of those. After 43-months long civil war and states disintegration in 1995, which resulted in 5 post-Yugoslav countries, Yugoslav Diaspora experienced radical changes. In Germany, one of the countries with the highest percentage of Yugoslav emigration, segregation on ethno-national grounds was empowered by the outbreak of the conflict: firstly on a socio-cultural level, and followed by changes on the level of institutional organizing. Psycho-emotional and financial involvement of Diaspora into the war is also not to be neglected. People of Serbian origin have been additionally overstrained with the designation of Serbs as war criminals in German media and the public sphere. In this way, the path from 'being a Yugoslav' toward 'becoming a Serb', outside nowadays Serbia, has been qualitatively different in comparison to potential identity shiftings experienced by other members of Former Yugoslav population. This paper is part of an ongoing PhD research and tackles biographical narratives of academics of Serbian origin in one German region. Paper addresses processes of post-Yugoslav identity negotiations in Diaspora settings, nationalistic tendentious among second generation youth, and discusses - based on NS-references founded in collected data - question of historicity of biographies.Keywords: biography, diaspora, ethnography, former republic of Yugoslavia, identity

Procedia PDF Downloads 391589 A Diagnostic Comparative Analysis of on Simultaneous Localization and Mapping (SLAM) Models for Indoor and Outdoor Route Planning and Obstacle Avoidance
Authors: Seyed Esmail Seyedi Bariran, Khairul Salleh Mohamed Sahari
Abstract:
In robotics literature, the simultaneous localization and mapping (SLAM) is commonly associated with a priori-posteriori problem. The autonomous vehicle needs a neutral map to spontaneously track its local position, i.e., “localization” while at the same time a precise path estimation of the environment state is required for effective route planning and obstacle avoidance. On the other hand, the environmental noise factors can significantly intensify the inherent uncertainties in using odometry information and measurements obtained from the robot’s exteroceptive sensor which in return directly affect the overall performance of the corresponding SLAM. Therefore, the current work is primarily dedicated to provide a diagnostic analysis of six SLAM algorithms including FastSLAM, L-SLAM, GraphSLAM, Grid SLAM and DP-SLAM. A SLAM simulated environment consisting of two sets of landmark locations and robot waypoints was set based on modified EKF and UKF in MATLAB using two separate maps for indoor and outdoor route planning subject to natural and artificial obstacles. The simulation results are expected to provide an unbiased platform to compare the estimation performances of the five SLAM models as well as on the reliability of each SLAM model for indoor and outdoor applications.Keywords: route planning, obstacle, estimation performance, FastSLAM, L-SLAM, GraphSLAM, Grid SLAM, DP-SLAM

Authors: Hsin-Yi Huang
Abstract:
This study mainly discussed the disease-induced and surgery-induced physical, psychological, and spiritual issues faced by a patient who suffered from emphysema and respiratory failure and had underwent a right-lung transplantation surgery. Nursing care was provided from May 21 to May 29. Based on the observations, interviews, physical examinations, and evaluations that were carried out using Roy’s adaptation model, the following nursing issues were identified: risk of infection, lack of knowledge, and anxiety. Active care was provided and a good nursing relationship with the patient and the patient’s family was established. The four strategies of Bandura’s self-efficacy theory (self-transcendence, vicarious experience, verbal persuasion, and biofeedback) were employed. Instructions for the appropriate rehabilitation exercises were given, immunosuppressant concentration was monitored, and special measures were taken to prevent infection. The patient was encouraged to express feelings and was provided with sufficient information to alleviate anxiety. With assistance from nursing personnel and the medical team, the patient was successfully discharged from the hospital and thereafter embarked on the path of postoperative recovery. The patient learned about the importance of home self-care and regular follow-up outpatient visits, and patient management was implemented for discharge preparation services. This nursing case study may serve as a reference to nurses managing similar cases in future.Keywords: anxiety, lung transplantation, Roy's adaptation model, self-efficacy theory

Authors: Azizah Ismail, Zainab Khalifah, Abbas Mardani
Abstract:
Sustainable community-based tourism through homestay programme is a growing niche market that has impacted destinations in many countries including Malaysia. With demand predicted to continue increasing, the importance of the homestay product will grow in the tourism industry. This research examines the sustainability criteria for homestay programme in Malaysia covering economic, socio-cultural and environmental dimensions. This research applied a two-stage methodology for data analysis. Specifically, the researcher implements a hybrid method which combines two multi-criteria decision making approaches. In the first stage of the methodology, the Decision Making Trial and Evaluation Laboratory (DEMATEL) technique is applied. Then, Analytical Network Process (ANP) is employed for the achievement of the objective of the current research. After factors identification and problem formulation, DEMATEL is used to detect complex relationships and to build a Network Relation Map (NRM). Then ANP is used to prioritize and find the weights of the criteria and sub-criteria of the decision model. The research verifies the framework of multi-criteria for sustainable community-based tourism from the perspective of stakeholders. The result also provides a different perspective on the importance of sustainable criteria from the view of multi-stakeholders. Practically, this research gives the framework model and helps stakeholders to improve and innovate the homestay programme and also promote community-based tourism.Keywords: community-based tourism, homestay programme, sustainable tourism criteria, sustainable tourism development

Authors: Taylin L. Peoples, Lauren Lewis, Sebastian G. Risco, Devin Mills
Abstract:
The impact of problematic drinking (PD) on the health of U.S. adults continues to be a concerning issue. Additionally, the U.S. Surgeon General recently highlighted the isolation epidemic, bringing attention to the significant and detrimental impact of loneliness. Research has found PD to be associated with deficits in feeling connection towards others. This suggests that one consequence of the isolation epidemic is the greater severity of PD. Further, PD has long been associated with three dark personality traits (i.e., narcissism, Machiavellianism, psychopathy), which may be explained by interpersonal factors but has yet to be examined. Therefore, the present study assessed the extent to which thwarted belongingness (TB) and perceived burdensomeness (PB) explain the relationship between dark personality traits and PD. Data was collected from 606 US adults reporting alcohol consumption. The participants completed the Interpersonal Needs Questionnaire, the Short Dark Triad scale, and the Alcohol Use Disorders Identification Test. Results from a path analysis supported the hypothesis that dark traits are associated with more severe PD through both PB and TB. The present results underscore the role of connection to others, as defined by TB and PB, in facilitating the relationship between dark personality traits and PD. Future research is needed in this area to develop preventative strategies and policies as well as clinical interventions. In sum, the findings offer a novel perspective on the intersection of personality traits, PB and TB, and PD.Keywords: problem drinking, personality, dark traits, dark traid, thwarted belonginess, perceived burdensomeness
Procedia PDF Downloads 40585 Energy Efficient Clustering with Reliable and Load-Balanced Multipath Routing for Wireless Sensor Networks
Authors: Alamgir Naushad, Ghulam Abbas, Shehzad Ali Shah, Ziaul Haq Abbas
Abstract:
Unlike conventional networks, it is particularly challenging to manage resources efficiently in Wireless Sensor Networks (WSNs) due to their inherent characteristics, such as dynamic network topology and limited bandwidth and battery power. To ensure energy efficiency, this paper presents a routing protocol for WSNs, namely, Enhanced Hybrid Multipath Routing (EHMR), which employs hierarchical clustering and proposes a next hop selection mechanism between nodes according to a maximum residual energy metric together with a minimum hop count. Load-balancing of data traffic over multiple paths is achieved for a better packet delivery ratio and low latency rate. Reliability is ensured in terms of higher data rate and lower end-to-end delay. EHMR also enhances the fast-failure recovery mechanism to recover a failed path. Simulation results demonstrate that EHMR achieves a higher packet delivery ratio, reduced energy consumption per-packet delivery, lower end-to-end latency, and reduced effect of data rate on packet delivery ratio when compared with eminent WSN routing protocols.Keywords: energy efficiency, load-balancing, hierarchical clustering, multipath routing, wireless sensor networks
Procedia PDF Downloads 87584 Application of Bim Model Data to Estimate ROI for Robots and Automation in Construction Projects
Authors: Brian Romansky
Abstract:
There are many practical, commercially available robots and semi-autonomous systems that are currently available for use in a wide variety of construction tasks. Adoption of these technologies has the potential to reduce the time and cost to deliver a project, reduce variability and risk in delivery time, increase quality, and improve safety on the job site. These benefits come with a cost for equipment rental or contract fees, access to specialists to configure the system, and time needed for set-up and support of the machines while in use. Calculation of the net ROI (Return on Investment) requires detailed information about the geometry of the site, the volume of work to be done, the overall project schedule, as well as data on the capabilities and past performance of available robotic systems. Assembling the required data and comparing the ROI for several options is complex and tedious. Many project managers will only consider the use of a robot in targeted applications where the benefits are obvious, resulting in low levels of adoption of automation in the construction industry. This work demonstrates how data already resident in many BIM (Building Information Model) projects can be used to automate ROI estimation for a sample set of commercially available construction robots. Calculations account for set-up and operating time along with scheduling support tasks required while the automated technology is in use. Configuration parameters allow for prioritization of time, cost, or safety as the primary benefit of the technology. A path toward integration and use of automatic ROI calculation with a database of available robots in a BIM platform is described.Keywords: automation, BIM, robot, ROI.

Procedia PDF Downloads 46582 Three-Dimensional CFD Modeling of Flow Field and Scouring around Bridge Piers
Authors: P. Deepak Kumar, P. R. Maiti
Abstract:
In recent years, sediment scour near bridge piers and abutment is a serious problem which causes nationwide concern because it has resulted in more bridge failures than other causes. Scour is the formation of scour hole around the structure mounted on and embedded in erodible channel bed due to the erosion of soil by flowing water. The formation of scour hole around the structures depends upon shape and size of the pier, depth of flow as well as angle of attack of flow and sediment characteristics. The flow characteristics around these structures change due to man-made obstruction in the natural flow path which changes the kinetic energy of the flow around these structures. Excessive scour affects the stability of the foundation of the structure by the removal of the bed material. The accurate estimation of scour depth around bridge pier is very difficult. The foundation of bridge piers have to be taken deeper and to provide sufficient anchorage length required for stability of the foundation. In this study, computational model simulations using a 3D Computational Fluid Dynamics (CFD) model were conducted to examine the mechanism of scour around a cylindrical pier. Subsequently, the flow characteristics around these structures are presented for different flow conditions. Mechanism of scouring phenomenon, the formation of vortex and its consequent effect is discussed for a straight channel. Effort was made towards estimation of scour depth around bridge piers under different flow conditions.Keywords: bridge pier, computational fluid dynamics, multigrid, pier shape, scour
Procedia PDF Downloads 297581 A Critique of The English And Nigerian Marine Insurance Laws on Insurable Interest
Authors: Omotolani Victoria Somoye
Abstract:
The paper examines modern approaches to the insurable interest, which is a fundamental principle of insurance law that affects the enforceability of insurance contracts. The study starts by examining the competing definitions of the nature of the insurable interest doctrine. It finds that while legal interest theory is seen to be sufficient as the test of insurable interest, the paper argues on how this approach deprives the insured of a full indemnity of losses suffered. The problem with the Nigerian and English current legislative framework is that it defines insurable interest as a legally recognized interest of the insured in the subject matter of insurance. However, other countries like Australia, the United States, South Africa, and more recently, Canada, have rejected the English test and trodden their own path along the factual expectancy line. The study justifies the rationale behind the departure of similar common law jurisdictions and argues that the English and Nigerian position, which appears to be too rigid, harsh on the insured, and no longer fit for purpose in the 21st century, should be revised. The paper concludes that the common law doctrine does not represent better interests of certainty, justice, and fairness, as well as not meeting the policy behind the requirement of insurable interest. This paper adopts a doctrinal comparative research methodology to examine complex areas of insurable interest in selected countries and work out some suggestions for reforming the Nigerian and English laws by referring to the approaches of other jurisdictions.Keywords: Australia, common law, English law, insurable interest, insurance, Nigeria

Authors: Myoungsoon You, Heejung Son
Abstract:
During a pandemic, hospital workers should protect not only their vulnerable patients but also themselves from the consequences of rapidly spreading infection. However, the evidence on the psychological impact of an outbreak on hospital workers is limited. In this study, we aim to assess hospital workers’ psychological well-being and function at the workplace after an outbreak, by focusing on ‘psychological resilience’. Specifically, the effects of risk appraisal, emotional experience, and coping ability on resilience indicated by the likelihood of post-traumatic syndrome disorder and willingness to work were investigated. Such role and position of each factor were analyzed using a path model, and the result was compared between the healthcare worker and non-healthcare worker groups. In the investigation, 280 hospital workers who experienced the 2015 Middle East Respiratory Syndrome outbreak in South Korea have participated. The result presented, in both groups, the role of the appraisal of risk and coping ability appeared consistent with a previous research, that was, the former interrupted resilience while the latter facilitated it. In addition, the role of emotional experience was highlighted as, in both groups, emotional disruption not only directly associated with low resilience but mediated the effect of perceived risk on resilience. The differences between the groups were also identified, which were, the role of emotional experience and coping ability was more prominent in the non-HCW group in explaining resilience. From the results, implications on how to support hospital personnel during an outbreak in a way to facilitate their resilience after the outbreak were drawn.Keywords: hospital workers, emotions, infectious disease outbreak, psychological resilience

Authors: Yeliz Karaca, Rana Karabudak
Abstract:
Multifractal Denoising techniques are used in the identification of significant attributes by removing the noise of the dataset. Magnetic resonance (MR) image technique is the most sensitive method so as to identify chronic disorders of the nervous system such as Multiple Sclerosis. MRI and Expanded Disability Status Scale (EDSS) data belonging to 120 individuals who have one of the subgroups of MS (Relapsing Remitting MS (RRMS), Secondary Progressive MS (SPMS), Primary Progressive MS (PPMS)) as well as 19 healthy individuals in the control group have been used in this study. The study is comprised of the following stages: (i) L2 Norm Multifractal Denoising technique, one of the multifractal technique, has been used with the application on the MS data (MRI and EDSS). In this way, the new dataset has been obtained. (ii) The new MS dataset obtained from the MS dataset and L2 Multifractal Denoising technique has been applied to the K-Means and Fuzzy C Means clustering algorithms which are among the unsupervised methods. Thus, the clustering performances have been compared. (iii) In the identification of significant attributes in the MS dataset through the Multifractal denoising (L2 Norm) technique using K-Means and FCM algorithms on the MS subgroups and control group of healthy individuals, excellent performance outcome has been yielded. According to the clustering results based on the MS subgroups obtained in the study, successful clustering results have been obtained in the K-Means and FCM algorithms by applying the L2 norm of multifractal denoising technique for the MS dataset. Clustering performance has been more successful with the MS Dataset (L2_Norm MS Data Set) K-Means and FCM in which significant attributes are obtained by applying L2 Norm Denoising technique.Keywords: clinical decision support, clustering algorithms, multiple sclerosis, multifractal techniques

Authors: Thendiyath Roshni, Stefano Pagliara
Abstract:
Block ramps (BR) or rock chutes are eco-friendly natural river restoration structures. BR are made of ramp of rocks and flows over BR develop turbulence and helps in the entrainment of ambient air. These act as natural aerators in river flow and therefore leads to oxygenation of water. As many of the hydraulic structures in rivers, hinders the natural path for aquatic habitat. However, flows over BR ascertains a natural rocky flow and ensures safe and natural movement for aquatic habitat. Hence, BR is considered as a better alternative for drop structures. As water quality is concerned, turbulent and aerated flows over BR or macro-roughness conditions improves aeration and thereby oxygenation. Hence, the objective of this paper is to study the oxygenation in the turbulent flows over BR. Experimental data were taken for a slope (S) of 27.5% for three discharges (Q = 9, 15 and 21 lps) conditions. Air concentration were measured with the help of air concentration probe for three different discharges in the uniform flow region. Oxygen concentration is deduced from the air concentration as ambient air is entrained in the flows over BR. Air concentration profiles and oxygen profiles are plotted in the uniform flow region for three discharges and found that air concentration and oxygen concentration does not show any remarkable variation in properties in the longitudinal profile in uniform flow region. An empirical relation is developed for finding the average oxygen concentration (Oₘ) for S = 27.5% in the uniform flow region for 9 < Q < 21 lps. The results show that as the discharge increases over BR, there is a reduction of oxygen concentration in the uniform flow region.Keywords: aeration, block ramps, oxygenation, turbulent flows

Authors: Jeremy Schultz
Abstract:
The purpose of this study was to understand the perceptions of vineyard managers in the Krasnodar Region of Southern Russia located between the city of Kransnodar and the Black Sea. In recent years, wine tourism throughout the region has seen tremendous growth due in part to the concurrent growth in the number of tourists vacationing at the Black Sea. This trend has contributed to the development of large-scale wine operations developing in numerous rural locations along the tourists’ travel path. Niche areas of tourism, such as wine tourism, have proven to provide economic viability for rural communities all around the world. Understanding their shared group characteristics while honoring their unique qualities as individuals aids in responsible wine tourism development that provides a sense of well-being for the communities and stakeholders involved. Semi-structured interviews and lived experience methodologies were used in locations that were associated with wine food tourism operations. By understanding management perspectives, it lends insight into sustainable destination management and wine tourism product development, furthering our progress toward ethical, responsible, and financially feasible operations. This research also represents a collaborative effort between Russia and the United States that supports an agenda of sustainable destination development and management. As a global community, we need to continue to investigate stakeholder perceptions and strategic management techniques that best support the pillars upon which responsible tourism was founded.Keywords: wine tourism, tourism development, Russia, rural tourism

Abstract:
The historical cities in the third world suffer from many environmental problems; one of them is the spread of visual pollution manifestations. These phenomena increase with low levels of public awareness and low per capita income. The historical city of Ibb is suffering from a variety of visual pollution of the urban environment, so it has been chosen as a case study. This study aims to identify the difficulty and complexity of dealing with visual pollutions manifestations in the historical city of Ibb, and to provide appropriate solutions, which suit with the complex and contradictory circumstances. The study relies on an inductive approach to achieve its aims through two methods; the first is a visual survey of the visual pollution phenomenon based on images and researcher notes. The Second method is the analyses of the opinions and impressions of the city's residents and visitors through interviews, in addition to interviews with the officials in the competent authorities, and some specialists in the field of urban environment. Through the results of the field study and discussion of the interview results, this study presents an analysis of the phenomenon of visual distortion of the historical city of Ibb regarding the appearances and the reasons. Furthermore, this study provides appropriate solutions, which suitable with the complex and contradictory circumstances. These solutions take two paths: the first one is to stop the spread of visual distortions, and the second path is to address the current visual pollutions.Keywords: visual pollution, visual image, urban environment, difficulty, complexity, historical cities, the historical city of Ibb

Authors: Sergio A. Carvalho, Jose Pinto-Gouveia, David Gillanders, Paula Castilho
Abstract:
The role of psychological processes has long been recognized as crucial factors in depressive symptoms in chronic pain (CP). Although some studies have explored the negative impact of being entangled with internal experiences (e.g., thoughts, emotions, physical sensations) – cognitive fusion, it is not extensively explored 1) whether these are pain-related or rather general difficult experiences, and 2) how they relate to experiencing obstacles in committing to valued actions. The current study followed a cross-sectional design in a sample of 231 participants with CP, in which a mediational model was tested through path analyses in AMOS software. The model presented a very good model fit (Χ²/DF = 1.161; CFI = .999; TLI = .996; RMSEA = .026, PCLOSE = .550.), and results showed that pain intensity was not directly related to depressive symptoms (β = .055; p = .239) but was mediated by cognitive fusion with both general and pain-related internal experiences (β = .181, 95%CI [.097; .271]; p = .015). Additionally, results showed that only general cognitive fusion (but not pain-specific fusion) was associated with experiencing obstacles to living a meaningful life, which mediated its impact on depressive symptoms (β = .197, 95%CI [.102; .307]; p = .001). Overall, this study adds on current literature by suggesting that psychological interventions to pain management should not be focused only on management of pain-related experiences, but also on developing more effective ways of relating to overall internal experiences.Keywords: cognitive fusion, chronic pain, depressive symptoms, valued living

Authors: Rahmat Hajimineh, Ebrahim Rezaei Rad
Abstract:
The war between Russia and Ukraine is considered a very important event in international relations, especially after the end of the Cold War, a war that has had wide dimensions since its beginning. Dimensions that, in addition to political issues, have especially affected the world economy and especially the two countries. The most important issue in the field of the economy that was affected by the war between Russia and Ukraine was the issue of energy. Russia is one of the largest producers and suppliers of natural gas for European countries, and 40% of European gas is supplied by Russia. For this reason, it is natural that European countries have problems in this regard. On the other hand, Ukraine is considered the gateway to Europe for Russia regarding the export of natural gas. The war in Ukraine has had severe effects on gas and energy in Europe. From this point of view, European countries are looking to diversify their energy path by switching to renewable energies, and they are also looking at other energy-producing countries like Qatar to meet their energy needs. In this article, we are trying to investigate the impact of the war between Russia and Ukraine on Qatar's policies in the field of fossil and renewable energy. The descriptive-analytical method and the theoretical framework of energy security have been used to review this article. Based on this, the article examines the situation of fossil and renewable energies in Qatar and, on the other hand, the effects of the war in Ukraine on both energies in Qatar. The findings of this article also indicate that Qatar has made changes in its energy policies after the war in Ukraine, which seems to be possible due to its high potential, especially in the field of renewable and fossil energy. There is an export of surplus production of this country to other countries, especially European countries.Keywords: Ukraine War, fossil fuels, renewable energy, energy security, Qatar

Authors: J. S. Dhillon, K. K. Dhaliwal
Abstract:
In almost all the digital filtering applications the digital infinite impulse response (IIR) filters are preferred over finite impulse response (FIR) filters because they provide much better performance, less computational cost and have smaller memory requirements for similar magnitude specifications. However, the digital IIR filters are generally multimodal with respect to the filter coefficients and therefore, reliable methods that can provide global optimal solutions are required. The artificial bee colony (ABC) algorithm is one such recently introduced meta-heuristic optimization algorithm. But in some cases it shows insufficiency while searching the solution space resulting in a weak exchange of information and hence is not able to return better solutions. To overcome this deficiency, the opposition based learning strategy is incorporated in ABC and hence a modified version called oppositional artificial bee colony (OABC) algorithm is proposed in this paper. Duplication of members is avoided during the run which also augments the exploration ability. The developed algorithm is then applied for the design of optimal and stable digital IIR filter structure where design of low-pass (LP) and high-pass (HP) filters is carried out. Fuzzy theory is applied to achieve maximize satisfaction of minimum magnitude error and stability constraints. To check the effectiveness of OABC, the results are compared with some well established filter design techniques and it is observed that in most cases OABC returns better or atleast comparable results.Keywords: digital infinite impulse response filter, artificial bee colony optimization, opposition based learning, digital filter design, multi-parameter optimization

Authors: Kartik Thakore, Anna-Roza Tamas, Adam Cole
Abstract:
The world health organization (WHO) reports that by 2030 more than 23.7 million deaths annually will be caused by Cardiovascular Diseases (CVDs); with a 2008 economic impact of $3.76 T. Metabolic syndrome is a disorder of multiple metabolic risk factors strongly indicated in the development of cardiovascular diseases. Guided lifestyle intervention driven by live coaching has been shown to have a positive impact on metabolic risk factors. Individuals’ path to improved (decreased) metabolic risk factors are driven by personal motivation and personalized messages delivered by coaches and augmented by technology. Using interactions captured between 400 individuals and 3 coaches over a program period of 500 days, a preliminary model was designed. A novel real time event tracking system was created to track and classify clients based on their genetic profile, baseline questionnaires and usage of a mobile application with live coaching sessions. Classification of clients and coaches was done using a support vector machines application build on Apache Spark, Stanford Natural Language Processing Library (SNLPL) and decision-modeling.Keywords: guided lifestyle intervention, metabolic risk factors, personal coaching, support vector machines application, Apache Spark, natural language processing

Authors: Nedjar Abdelhadi
Abstract:
The pharmaceutical industry is one of the most important structures and foundations for the management and development of the modern world, especially the advanced part of it, meaning that there are some exceptions for third-world countries. The world today has witnessed radical transformations and changes, some of which made it better and some of which affected the path of its growth. At the beginning of my research, there was a detailed presentation overview of the current situation of the world in terms of growth and development, and it proceeded through that overview as the introduction to my research. The first chapter had divided into three sections; each topic was unique to one of the new methods of manufacturing, deducing and developing medicines Several examples of various recently developed medicines were used The second chapter dealt with the defects and shortcomings that pioneers and drug makers at various levels, as well as various regions and major companies, suffer from on the basis that they are international, especially those specialized in the manufacture of medicines related to viruses and chronic diseases, as well as incurable. As for the third chapter, it was devoted to marketing methods, methods of achieving sales, as well as the basics of spreading medicines and preparing the minds of consumers. Through my research, the one concluded that the current world has become completely different from the world we used to know, and it means by saying the field of manufacturing, selling and marketing medicines. It was noted that one of the biggest factors that affected the change in the field of medicine was the corona disaster. At the end of my research, I was left with nothing but to show the importance and necessity of the pharmaceutical industry and its effective role, not only in the development of mankind, but its main role is in the survival of mankind.Keywords: health, diseases, medicine, epidemics

Authors: Mohamed Muse Hassan
Abstract:
Selling through the Internet is changing the norms of doing business globally. Today, selling and buying from the Internet is not only an option but the dominant form of shopping. But, this phenomenon is not thriving in the developing countries, mainly in Africa. Therefore, although previous studies focused on the e-retailers’ side, this study investigates the effect of consumer trust and online payment options on the awareness and perception of e-commerce in Africa. We developed a five-construct model and empirically tested the model by targeting professionals and college students who reside in Somalia. We employed structural equation modeling (SEM) technique for path analysis to probe answers for the variables under study. The main findings of the study show that there is significant evidence that online payment option impacts both the awareness level and perception of e-commerce in Somalia. Consumer trust was also found to determine both the awareness and perception of online shopping in the country. Moreover, the current global payment options available ignore local technologies popular in Africa. For example, the inclusion of a mobile payment option alone would make a big difference in Africa. The paper also determined that consumer trust toward online retailers is very low and this can be solved if consumers are given assurances for their financial transactions. The paper concludes that increased online payment options are needed in Somalia and, in Africa, in general. Limitations and further research suggestions are also included at the end of this paper.Keywords: Africa, consumer trust, e-commerce, online payment

Abstract:
Alcohol fuels are renewable, have low pollution and have high octane number; therefore, they are important as fuel in internal combustion engines. Percentage detection of these alcoholic fuels with gasoline is a complicated, time consuming, and expensive process. Nowadays, these processes are done in equipped laboratories, based on international standards. The aim of this research is to determine percentage detection of different fuels based on vibration analysis of engine block signals. By doing, so considerable saving in time and cost can be achieved. Five different fuels consisted of pure gasoline (G) as base fuel and combination of this fuel with different percent of ethanol and methanol are prepared. For example, volumetric combination of pure gasoline with 10 percent ethanol is called E10. By this convention, we made M10 (10% methanol plus 90% pure gasoline), E30 (30% ethanol plus 70% pure gasoline), and M30 (30% Methanol plus 70% pure gasoline) were prepared. To simulate real working condition for this experiment, the vehicle was mounted on a chassis dynamometer and run under 1900 rpm and 30 KW load. To measure the engine block vibration, a three axis accelerometer was mounted between cylinder 2 and 3. After acquisition of vibration signal, eight time feature of these signals were used as inputs to an Adaptive Neuro Fuzzy Inference System (ANFIS). The designed ANFIS was trained for classifying these five different fuels. The results show suitable classification ability of the designed ANFIS network with 96.3 percent of correct classification.Keywords: internal combustion engine, vibration signal, fuel composition, classification, ANFIS
