Authors: Apoorva Bamal, Agnieszka Indiana Olbert
Abstract:
Floods are known to be one of the most devastating hydro-climatic events, impacting a wide range of stakeholders in terms of environmental, social and economic losses. With difference in inundation durations and level of impact, flood hazards are of different degrees and strength. Amongst various set of domains being impacted by floods, environmental degradation in terms of water quality deterioration is one of the majorly effected but less highlighted domains across the world. The degraded water quality is caused by numerous natural and anthropogenic factors that are both point and non-point sources of pollution. Therefore, it is essential to understand the nature and source of the water pollution due to flooding. The major impact of floods is not only on the physico-chemical water quality parameters, but also on the biological elements leading to a vivid influence on the aquatic ecosystem. This deteriorated water quality is impacting many water categories viz. agriculture, drinking water, aquatic habitat, and miscellaneous services requiring an appropriate water quality to survive. This study identifies, reviews, evaluates and assesses multiple researches done across the world to determine the impact of floods on water quality. With a detailed statistical analysis of top relevant researches, this study is a synopsis of the methods used in assessment of impact of floods on water quality in different geographies, and identifying the gaps for further abridgement. As per majority of the studies, different flood magnitudes have varied impact on the water quality parameters leading to either increased or decreased values as compared to the recommended values for various categories. There is also an evident shift of the biological elements in the impacted waters leading to a change in its phenology and inhabitants of the specified water body. This physical, chemical and biological water quality degradation by floods is dependent upon its duration, extent, magnitude and flow direction. Therefore, this research provides an overview into the multiple impacts of floods on water quality, along with a roadmap of way forward to an efficient and uniform linkage of floods and impacted water quality dynamics.Keywords: floods, statistical analysis, water pollution, water quality

Authors: Kwadwo Yeboah
Abstract:
Background and Aims: The adoption of International Accounting Standards (IAS) is considered to be one of the most significant developments in the accounting profession. The adoption of IAS aims to improve financial reporting quality by ensuring that financial information is transparent and comparable across borders. However, there is a lack of research on the impact of IAS on financial reporting quality in emerging economies. This study aims to fill this gap by evaluating the impact of IAS on financial reporting quality in emerging economies. Methods: This study uses a sample of firms from emerging economies that have adopted IAS. The sample includes firms from different sectors and industries. The financial reporting quality of these firms is measured using financial ratios, such as earnings quality, financial leverage, and liquidity. The data is analyzed using a regression model that controls for firm-specific factors, such as size and profitability. Results: The results show that the adoption of IAS has a positive impact on financial reporting quality in emerging economies. Specifically, firms that adopt IAS exhibit higher earnings quality and lower financial leverage compared to firms that do not adopt IAS. Additionally, the adoption of IAS has a positive impact on liquidity, suggesting that firms that adopt IAS have better access to financing. Conclusions: The findings of this study suggest that the adoption of IAS has a positive impact on financial reporting quality in emerging economies. The results indicate that IAS adoption can improve transparency and comparability of financial information, which can enhance the ability of investors to make informed investment decisions. The study contributes to the literature by providing evidence of the impact of IAS adoption in emerging economies. The findings of this study have implications for policymakers and regulators in emerging economies, as they can use this evidence to support the adoption of IAS and improve financial reporting quality in their respective countries.Keywords: accounting, international, standards, finance

Procedia PDF Downloads 1349197 Analysis of Cultural Influences on Quality Management by Comparison of Japanese and German Enterprises
Authors: Hermann Luecken, Young Won Park, Judith M. Puetter
Abstract:
Quality is known to be the accordance of product characteristics and customer requirements. Both the customer requirements and the assessment of the characteristics of the product with regard to the fulfillment of customer requirements are subject to cultural influences. Of course, the processes itself which lead to product manufacturing is also subject to cultural influences. In the first point, the cultural background of the customer influences the quality, in the second point, it is the cultural background of the employees and the company that influences the process itself. In times of globalization products are manufactured at different locations around the world, but typically the quality management system of the country in which the mother company is based is used. This leads to significantly different results in terms of productivity, product quality and process efficiency at the different locations, although the same quality management system is in use. The aim of an efficient and effective quality management system is therefore not doing the same at all locations, but to have the same result at all locations. In the past, standardization was used to achieve the same results. Recent investigations show that this is not the best way to achieve the same characteristics of product quality and production performance. In the present work, it is shown that the consideration of cultural aspects in the design of processes, production systems, and quality management systems results in a significantly higher efficiency and a quality improvement. Both Japanese and German companies were investigated with comparative interviews. The background of this selection is that in most cases the cultural difference regarding industrial processes between Germany and Japan is high. At the same time, however, the customer expectations regarding the product quality are very similar. Interviews were conducted with experts from German and Japanese companies; in particular, companies were selected that operate production facilities both in Germany and in Japan. The comparison shows that the cultural influence on the respective production performance is significant. Companies that adapt the design of their quality management and production systems to the country where the production site is located have a significantly higher productivity and a significantly higher quality of the product than companies that work with a centralized system.Keywords: comparison of German and Japanese production systems, cultural influence on quality management, expert interviews, process efficiency

Authors: Hatice Kahyaoglu Sut, Serap Unsar, Seda Kurt
Abstract:
The aim of this study is to investigate sexual quality of life in women with gynecological cancer. This cross-sectional study was conducted on 37 women with gynecological cancer and 39 control women (in menopausal term) at the Gynecooncology and Menopause Clinics of Trakya University Medical Faculty between January and July 2015. Women who had sexual active and willing to participate in the study filled an information form inquiring socio-demographic characteristics and Sexual Quality of Life Questionnaire-Female (SQLQ-F). Data were analyzed by Mann-Whitney-U test and Kruskal-Wallis test. The average age of the women was 52.7 ± 7.6 (51.2 ± 8.7 in women with gynecological cancer, 54.3 ± 6.0 in controls). The SQOL-F scores in women with gynecologic cancer (60.8 ± 22.4) was lower than controls (63.5 ± 20.7), however, there was no statistically significant difference (p = 0.759). Women with gynecological cancer who had vaginal dryness and pain during sexual intercourse (45.7 ± 21.3) were lower SQOL-F total score than control group (66.0 ± 21.7) (p = 0.014). The SQOL-F scores in women who took chemotherapy treatment (55.7 ± 17.8) were lower than in women who had not chemotherapy treatment (86.8 ± 16.6) (p = 0.005). In conclusion, taking chemotherapy treatment and occurring vaginal dryness and pain complaints during sexual intercourse in women with gynecological cancer reduces sexual quality of life. Therefore, sexual quality of life in women with gynecological cancer should be evaluated, and they should be supported in order to improve their sexual quality of life.Keywords: gynecological cancer, quality of life, sexuality, women

Authors: Zubana Afzal, Afsheen Massod
Abstract:
This quantitative study was carried out in order to explore the role of coping strategies as an explanatory mechanism in the relationship between self-determination needs and quality of life. A cross-sectional survey research design was conducted using scales such as the Basic Psychological Needs Scale (Deci&Ryan, 2000) to measure self-determination-based needs, Pain Coping Strategies Questionnaire (Harland &Georgieff, 2003), and Quality of Life Brief (The WHOQOL Group, 1998), in translated form in addition to a demographic information sheet. The sample comprised 120 (Women=63, Men=57), taken from different hospitals in Lahore, Multan, and Gojra. Descriptive and Inferential analyses were executed through SPSS version 23.00. All self-determination needs were found in result to be significantly and positively correlated with diversion and cognitive pain coping strategies, physical, psychological, social, and environmental quality of life, and significantly negatively correlated with catastrophizing and reinterpreting pain coping strategies. Cognitive and diversion pain coping strategies were found to be significantly and positively associated with all physical, psychological, social, and environmental quality of life. The regression analyses revealed that the strongest predictors were autonomy, cognitive and diversion pain coping strategies in predicting quality of life. All coping strategies except reinterpreting played a mediating role between self-determination needs and quality of life. The findings can lead to a better understanding of the role of self-determination needs and pain coping strategies in determining the quality of life among chronic non-specific lower back pain patients.Keywords: quality of life, chronic lower back pain, coping strategies, self determination needs

Authors: Joann Douziech
Abstract:
Individuals with intellectual and developmental disabilities (IDD) possess characteristics that present both challenges and gifts. Individuals with IDD require and are worthy of intentional, strategic, and specialized support throughout their lifespan to ensure optimum quality-of-life outcomes. The current global advocacy movement advancing the rights of individuals with IDD emphasizes a high degree of choice over life decisions. For some individuals, this degree of choice results in a variety of negative health and well-being outcomes. Improving the quality of life outcomes requires the combination of a commitment to the rights of the individual with a responsibility to provide support and choice commensurate with individual capacity. A belief that individuals with IDD are capable of learning and they are worthy of being taught provides the foundation for a holistic model of support throughout their lifespan. This model is based on three pillars of engineering the environment, promoting skill development and maintenance, and staff support. In an ever-changing world, supporting quality of life requires attention to moments, phases, and changes in stages throughout the lifespan. Balancing these complexities with strategic, responsive, and dynamic interventions enhances the quality of life of individuals with ID throughout their lifespan.Keywords: achieving optimum quality of life, comprehensive support, lifespan approach, philosophy and pedagogy

Authors: Fildzah Badzlina, Mega Puspa Sari
Abstract:
To rest the body after a full day of activities, the body needs sleep. During sleep, the body's response to external stimuli will be reduced and relatively inactive so that it is used to optimize the body's biological functions that cannot be done when awake. College students often experience poor sleep quality because of the dense activities carried out during the day. In addition, the level of physical activity of college students is also relatively low. Based on previous research, college students who have low physical activity have poor sleep quality. Therefore, the purpose of this study was to determine the relationship between physical activity and sleep quality in college students of the University of Muhammadiyah Prof. Dr. Hamka. This study used a cross-sectional research design with 107 respondents as research subjects. Samples were taken using the purposive sampling technique. The data was taken using a google form which was distributed to all college students in September 2021. The statistical test used was Chi-square. The results of this study showed that 85 (79.4%) college students experienced poor sleep quality during the Covid-19 Pandemic Period. Most respondents were 96 women (89.7%) and 32.7% (35 people) aged 20 years. In the pocket money category, most college students (71%) got pocket money less than 500.000 rupiahs per month. A total of 52 respondents (48.6%) had a moderate level of physical activity category. Poor sleep quality was more common in male students (90.9%) compared to female students (78.1%) (p>0.05). In the group with poor sleep quality, 88.9% of students were categorized in Rp. 500.001 to Rp. 1.000.000 for pocket money, 80.3% of students included in the category Rp. 500.000 or less, and 61.5% of students are included in the category of Rp. 1.000.000 or more. Poor sleep quality was more common among students in the age category 20 years (84.1%), compared to students in the age category > 20 years (71.1%). For the level of physical activity in the poor sleep quality group, 87% were included in the category of heavy physical activity, 82.7% included in the moderate level of physical activity, and 68.8% included in the category of low-level physical activity. There was no significant relationship between gender, pocket money, age, and physical activity with sleep quality (p>0.05).Keywords: college students, physical activity, sleep quality, university students

Authors: Xuguo Zhang, Jimmy Fung, Kenneth Leung, Alexis Lau
Abstract:
Fine particulate matter concentrations have been decreasing in the past few years while the ozone concentrations are posing an increasing trend in the Greater Bay Area (GBA) of China. A series of control policies have been released to mitigate the country-wide air pollution, however, how to effectively evaluate the exercised control measures and efficiently reveal potential projected mitigation pathways are still limited. By refining an enhanced air-quality-modeling system, this study provides an account of the air quality assessments from 2019 to 2025 to appraise the air quality results and improvement under designed scenarios for assessing the optimum scope for tightening the Air Quality Objectives (AQOs). The results show that it is doable to tighten the 24-hour AQO for SO2 from the World Health Objective air quality guidelines Interim Targets Level-1 (IT-1) (125μg/m3) to IT-2 level (50μg/m3) with the current number of exceedance allowed (three) remains unchanged. It is also possible to tighten the annual AQO for PM2.5 from IT-1 (35 μg/m3) to IT 2 (25 μg/m3), and its 24-hr AQO from IT-1 (75 μg/m3) to IT 2 (50 μg/m3) with the number of exceedances allowed increased from current nine to 35. Regional cooperation under the development of the GBA cooperation are still needed to be focused and strengthen due to the cross-boundary transport characteristics of the air pollution.Keywords: air quality attainment, Hong Kong, mitigation policy, chemical transport modeling, sensitivity analysis

Authors: Naim Ismajli, Ilir Rexhepi
Abstract:
The article presents the results of the study about the motives and efficiency of quality management system (Quality System, QS) implementation in Kosovo companies. The main purpose of the study was to find out why Kosovo companies seek the implementation and certification of QS in accordance with the requirements of the ISO 9001 series of the standards and what has changed after the QS implementation. Furthermore, the results of the research were compared with similar performed in the other European countries. The performed research revealed that the implementation of QS mostly results in the benefits of an intangible nature that are internal to the company. In addition, although the main reasons to start implementing QS are the expectations of the external advantages, the implementation results mostly in the increase of the internal benefits such as an improvement in the definition of the responsibilities and obligations of the employees, a decrease in the nonconformities, better communication among the employees, and increased efficiency.Keywords: quality management systems, ISO 9001, total quality management, environmental management system, ISO 14000, competitiveness, efciency

Authors: Urmi Khatri
Abstract:
Capital asset pricing model (CAPM) draws a direct relationship between the risk and the expected rate of return. There was a criticism on the beta and the assumptions of CAPM, as they are not applicable in the real world. Fama French Three Factor Model and Fama French Five Factor Model have given different factors, which have an impact on the return of any asset like size, value, investment and profitability. This study proposes to see Capital Asset pricing Model through the lenses of the quality aspect. In the study, the six factors are studied. The Fama French Five Factor Model and addition of the quality dimension are studied. Here, Graham’s seven quality and quantity criteria are measured to determine the score of the sample firms. Thus, this study tries to check the model fit. The beta coefficient of the quality dimension and the R square value is seen to determine validity of the proposed model. The sample is drawn from the firms listed on Indian Stock Exchange (BSE). For the study, only nonfinancial firms are been selected. The time period of the study is from January 1999 to December 2019. Hence, the primary objective of the study is to check how robust the model becomes after giving the quality dimension to the capital asset pricing model in addition to the size, value, profitability and investment.Keywords: asset pricing model, CAPM, Graham’s score, G-score, multifactor model, quality

Authors: Bingchun Liu, Pei-Chann Chang, Natasha Huang, Dun Li
Abstract:
Machine Learning and Data Mining are the two important tools for extracting useful information and knowledge from large datasets. In machine learning, classification is a wildly used technique to predict qualitative variables and is generally preferred over regression from an operational point of view. Due to the enormous increase in air pollution in various countries especially China, Air Quality Classification has become one of the most important topics in air quality research and modelling. This study aims at introducing a hybrid classification model based on information theory and Support Vector Machine (SVM) using the air quality data of four cities in China namely Beijing, Guangzhou, Shanghai and Tianjin from Jan 1, 2014 to April 30, 2016. China's Ministry of Environmental Protection has classified the daily air quality into 6 levels namely Serious Pollution, Severe Pollution, Moderate Pollution, Light Pollution, Good and Excellent based on their respective Air Quality Index (AQI) values. Using the information theory, information gain (IG) is calculated and feature selection is done for both categorical features and continuous numeric features. Then SVM Machine Learning algorithm is implemented on the selected features with cross-validation. The final evaluation reveals that the IG and SVM hybrid model performs better than SVM (alone), Artificial Neural Network (ANN) and K-Nearest Neighbours (KNN) models in terms of accuracy as well as complexity.Keywords: machine learning, air quality classification, air quality index, information gain, support vector machine, cross-validation

Within the quality standards framework, the fire response process is chronologically mapped. Individual variables within the sequence of events are identified. Through in-person data collection, questionnaires, interviews, and the expansion of the incident reporting system, this study identifies and categorizes previously unrecorded variables involved in the response phase of a fire. Following a data analysis of each variable using a quantitative or qualitative assessment, the variables are ranked pertaining to the magnitude of their impact to the event outcome. Among others, key indicators of quality performance in the analysis involve decision communication, resource utilization, response techniques, and response time. Through the application of this framework and subsequent utilization of quality standards indicators, there is potential to increase efficiency in the response phase of an emergency event; thereby saving additional lives, property, and resources.Keywords: emergency management, fire, quality standards, response

Abstract:
The sedimentological parameterization of shallow-marine siliciclastic reservoirs in terms of reservoir quality and heterogeneity from outcrop study can help improve the subsurface reservoir prediction. An architectural analysis has documented variations in sandstone geometry and rock properties within shallow-marine sandstone exposed in the Miocene Sandakan Formation of Sabah, Borneo. This study demonstrates reservoir sandstone quality assessment for subsurface rock evaluation, from well-exposed successions of the Sandakan Formation, Borneo, with which applicable analogues can be identified. The analyses were based on traditional conventional field investigation of outcrops, grain-size and petrographic studies of hand specimens of different sandstone facies and gamma-ray and permeability measurements. On the bases of these evaluations, the studied sandstone was grouped into three qualitative reservoir rock classes; high (Ø=18.10 – 43.60%; k=1265.20 – 5986.25 mD), moderate (Ø=17.60 – 37%; k=21.36 – 568 mD) and low quality (Ø=3.4 – 15.7%; k=3.21 – 201.30 mD) for visualization and prediction of subsurface reservoir quality. These results provided analogy for shallow marine sandstone reservoir complexity that can be utilized in the evaluation of reservoir quality of regional and subsurface analogues.Keywords: architecture and sedimentology, subsurface rock evaluation, reservoir quality, borneo

Authors: Kanyarat Bussaban, Siriporn Poolsuwan
Abstract:
This study is conducted with the objective to prove how the distorted distribution of welfare affects the quality of school-age children lives differently in the case of an urban community in Bangkok. 334 samples are households from Suan Oi and Ratchapatubtim communities. The study of sample communities found the difference between two community areas that are close. The people of Suan Oi community are economically better off people than the people of the Ratchapatubtim community. They share the benefits of using most services except the welfare of a child’s education. The resulting analysis of the variability in quality of life of the school age children indicate that heads of the households are women looking for quality of life benefits when the compulsory school age is less. A study of the two communities suggests that the inequality in income distribution currently affects the quality of life of school-age children.Keywords: inequality, income distribution, quality of school-age children lives, welfare state

Authors: Manjie Li, Xiangju Cheng, Yongcan Chen
Abstract:
With rapid development of industrialization and urbanization, water environmental deterioration is widespread in majority of urban rivers, which seriously affects city image and life satisfaction of residents. As an emergency measure to improve water quality, clean water diversion is introduced for water environmental management. Lubao River and Southwest River, two urban rivers in typical plain tidal river network, are identified as technically and economically feasible for the application of clean water diversion. One-dimensional hydrodynamic-water quality model is developed to simulate temporal and spatial variations of water level and water quality, with satisfactory accuracy. The mathematical model after calibration is applied to investigate hydrodynamic and water quality variations in rivers as well as determine the optimum operation scheme of water diversion. Assessment system is developed for evaluation of positive and negative effects of water diversion, demonstrating the effectiveness of clean water diversion and the necessity of pollution reduction.Keywords: assessment system, clean water diversion, hydrodynamic-water quality model, tidal river network, urban rivers, water environment improvement

Authors: Hung-Chi Chang
Abstract:
For an extended EPQ model with random yield, the existent study revealed that both the disaggregating and consolidating shipment policies for the imperfect quality items are independent of holding cost, and recommended a model with economic benefit by comparing the least total cost for each of the three models investigated. To better capture the real situation, we generalize the existent study to include different holding costs for perfect and imperfect quality items. Through analysis, we show that the above shipment policies are dependent on holding costs. Furthermore, we derive a simple decision rule solely based on the thresholds of problem parameters to select a superior model. The results are illustrated analytically and numerically.Keywords: consolidating shipments, disaggregating shipments, EPQ, imperfect quality, inventory

Authors: Manish Khanna
Abstract:
Higher education seeks to preserve, transmit and advance knowledge. It is one of the most important instruments of change and progress. The observation of Kothari Commission (1964-66) is true even today; The destiny of India is now being shaped in her classrooms. This, we believe, is no more rhetoric. In the world based on science and technology it is education that determines the level of prosperity, welfare, and security of the people. On the quality and number of persons coming out of our schools and colleges will depend our success in the great enterprise of national reconstruction.Keywords: higher education, quality in academics, Kothari commission, privatising higher education

Authors: Jaffry Zakaria, Nor Azlina Hasbullah
Abstract:
The research on water quality based on 'Water Quality Index' (WQI) has been on the run along Kampar River in Perak State of Malaysia. This study was conducted to achieve several key objective that determe the value of the parameters that were studied based on Water Quality Index (WQI). The parameters include Dissolved Oxygen (DO), pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Suspended Solids. In this study, three sampling stations were selected. Through observations from the researchers, several pollutions were found occurring along the research area such as the disposal of waste water directly without treatment from villagers, widespread dumping of solid waste and the development of the surrounding areas that contributed to the pollution of Sungai Kampar in Perak, Malaysia. Sungai Kampar is commonly used for water recreational activities as well as for bathing purposes. Results showed that Sungai Kampar is classified under category III. According to Interim National Water Quality Standard for Malaysia (INWQS), rivers in the third grade are clean but not suitable for river recreational activities. Therefore, there is a requirement to investigate and analysis the water quality of all white water rivers in Malaysia focusing on the area of water activities. The combination of technology and risk management based on risk assessments can help the recreational industry to survive in future.Keywords: risk assessments, White Water River, water quality index (WQI), Interim National Water Quality Standard for Malaysia (INWQS)

Abstract:
The purpose of this study was to investigate the quality of dissertation in humanities and social sciences in Thai private universities.Seven hundred and fifty dissertations of students graduating between 2007-2013 from 12 private universities were randomly sampled. The 5-point rating scale for the evaluation of the dissertations was developed. The rubric method was used in scoring. The overall content validity of the scale was .92. The individual content validities of the scale were ranged from .71 to 1.00. The concurrent validities were significant at the .01 level with the value from .849 to .959. The inter-rater reliabilities were significant related at the .01 level with the value from .810 to .959. The test-retest method was used to find the reliabilities and significant related at the .01 level with the value from .944 to .966. The descriptive statistics was used in the analysis of the collected data. The study found that, among 750 dissertations, those that were rated as excellent, above average, average standard, below standard, and need to be improved were, 0.1 %, 13.3 %, 74.7 %, 11.7 %, and 0.1 % respectively. It was, therefore, concluded that the overall quality of the dissertations was in accordance with the principle of the research methodology and the quality of the majority of the dissertations is closely related.Keywords: quality of dissertation, quality of dissertation in humanities and social sciences, private university, reliability
