There has been mixed support for the scale in several countries worldwide. Hence, this study examined the validity and reliability of the driver behavior questionnaire (DBQ) among a large sample of Nigerian commercial truck drivers. The structural equation modeling method was used to analyze the composite reliability and construct validity (Average Variance Extracted (AVE) and Heterotrait-Monotrait ratio). The authors found the constructs' composite reliability, convergent validity, and discriminant validity to be above 0.7, 0.5, and below 0.9, respectively, showing that they are valid and reliable for the sample of Nigerian commercial truck drivers. The novelty of this result is that the driver behavior questionnaire can be used to achieve consistent and valid results for a study of commercial truck drivers' behavior in Nigeria toward achieving RTA reduction.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42618794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two researchers prepared the study samples represented in non-woven with a thickness of 3 cm - 2 cm - 1.5 cm. The research objective lies in highlighting the role of recycling yarns and fabric remnants in reflecting ultraviolet rays, insulating heat, and determining the most appropriate thickness to getting the highest thermal insulation. The results were obtained with a thermal conductivity meter with hot square technology. There is a difference in the value of the thermal conductivity coefficient of the samples according to the thickness used. The higher the thickness of the sample, the lower the coefficient of thermal conductivity, and thus, the higher the thermal insulation value. The results of the thermal conductivity coefficient of the samples under study were, in general, significantly low, which indicates the success of the samples in isolating the surfaces well, as the value was between 0.032 and 0.0178. From here, it is possible to benefit from paper and fabric waste in the material savings resulting from the use of air conditioning devices and high-priced insulators. This is an attempt by the two researchers to save electricity consumption, which increases when air conditioners are used in places with high temperatures for a long time.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42273081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of population growth rates in the dam downstream area causes the number of populations that is impacted by disaster risk. In this research, there is conducted the danger class classification of dam failure based on the increasing number of population growth rates. In this research, there is conducted a class classification about the dam failure based on the increasing of population growth rate. The methodology is started from data collecting such as PMF design flood that is used for analyzing the dam break to be obtained the flood boundary of the dam downstream area, Map of the Digital Elevation Model that is for knowing the topography of the dam downstream area, population data which is obtained from BPS that is for knowing the population growth rate so it can predict the population number until the life time of the reservoir, and the land use data that is for knowing the population growth rate in the downstream dam area so it can be known the development of residence until the life time of reservoir. Then there is carried out the evaluation and assessment, which is based on the number of risk populations. The result show that there are 6 dams with very high danger level of the downstream damage level and the classification assessment of dams is extreme such as the dams of Bintang Bano, Rotiklot, Napungette, Lolak, Kuwil, and Pandanduri. However, the other four dams also show a very high danger level but in the assessment classification of dam is high (not extreme) such as the dams of Batu Nampar, Kengkang, Sepit, and Jangkih Jawa. The result is hoped can predict the danger classification of dam failure during the life time of the reservoir. Additionally, it can give input to the policymaker in determining the risk classification of dam failure. Moreover, it can be as one of the inputs in developing the risk classification model of dam failure.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45195524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Factors Influencing the Behavioural Intention of Patients with Chronic Diseases to Adopt IoT-Healthcare Services in Malaysia","authors":"Huda Hussein Mohammad Jawad, Zainuddin Bin Hassan, B. Zaidan","doi":"10.55463/issn.1674-2974.50.1.4","DOIUrl":"https://doi.org/10.55463/issn.1674-2974.50.1.4","url":null,"abstract":"The Internet of Things (IoT) in healthcare is the newest trend in the healthcare market. IoT allows healthcare providers to expand their reach beyond the usual clinical environment. They are driven to maximize the possibilities of digitally linked healthcare services to improve the user experience, diagnostic accuracy, and communication among healthcare professionals. Sensors, wearables, and health monitors have made healthcare cheaper, faster, and more effective. Despite the privileges of the IoT in healthcare services, the adoption rate of these services is still in the early stages. The aim of this research was to examine the adoption of IoT-enabled healthcare services among Malaysian chronic patients. To achieve this purpose, the study offered an integrated framework to investigate the influence of the identified factors on Behavioural Intention (BI) to adopt IoT healthcare services. The novelty lies in combining the Unified Theory of Acceptance and Use of Technology (UTAUT), the Theory of Organizational Environments for Technology Adoption (TOE), and the Social Exchange Theory (SE). Patients in Malaysia dealing with chronic illnesses were the subjects of an online survey. Eleven predicted predictive constructs' impacts were investigated using partial least square structural equation modeling. The findings revealed that individual and technological factors and their dimensions, significantly affected chronic disease patients’ BI toward IoT-healthcare services adoption. Similar results were observed for the effect of BI on Use Behaviour (UB). Meanwhile, trust partially mediated the effect of individual and technological-related factors on BI.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46192298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This negatively affects the development of the country and the promotion of the population as well as their profitability in society, which is explained by the scarcity of existing care centers for individuals in Morocco. This work aims to summarize the literature regarding help centers for children, adolescents, and other people, suffering from psychological disorders. We carried out a comparative study that constitutes a very fruitful approach consisting of a comparison between the forms of care centers in Africa, such as Morocco, Europe, such as France, America, such as Canada, and the United States through the comparisons of the general criteria between each quoted country. The results showed that the Anglophone model is the most successful and can be taken as a model to follow in the Moroccan context. Based on the results of this scientific study, it is clear that it is necessary to introduce the criteria used by the American model: the age category and the multidisciplinary team because they represent the pillars of the most successful healthcare center. In conclusion, the proper management of healthcare centers requires the interference of all existing models while taking advantage of the advantages and limitations of each experience.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48858101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this paradigm is confined to restricted resources; hence, an efficient and effective resource allocation strategy is necessary for optimum resource usage. Considering this fact, this article aims to describe a new method named the priority-based resource allocation scheme for efficient use of the available resources in this paradigm. Computing resources are allocated adaptively by considering the time-constraint nature of the incoming requests. The proposed approach shall adapt to meet the resource requirements and incoming requests' priorities to accomplish the task. After determining the received request type, which can be either a priority-based or ordinary request, each will be handled in one of three possibilities. At the edge node, available resources are managed in such a way as to handle the maximum number of incoming requests and the optimum use of scarce resources. Simulation results show that our proposed priority-based resource allocation scheme method outperforms the benchmarked schemes in average response time, average latency, resource usage, task execution time analysis, and energy consumption.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46401284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper compares the minimum sample sizes of two-sample t-test and the Wilcoxon rank-sum test under the arcsine distribution, based on their power [1, 2]. To accomplish this task, some essential probabilities that are useful in the power and sample size determination of the Wilcoxon rank-sum test were derived by the author for computing the approximated formula given by Lehmann [2]. The composite numerical integration algorithm is used to compute these probabilities, which are related to the arcsine distribution. In this study, a computer program was built by the author to find the exact (simulated) minimum sample sizes n for any significant level and power by iterating on n with starting points for n provided by the approximated formulas of [2, 3]. The scientific novelty of this research paper is determining the minimum sample sizes by considering a new set of the arcsine distribution shift alternatives of the forms giving the left-hand endpoint of the displaced distribution as the quantile of order p, 0 < p < 1, of the second distribution rather than using alternatives that specify as the quantile of order p, p < 0.5. As considered by [1], a choice that prevents losing some important alternative hypotheses is an extension to the set of alternative hypotheses considered by Guenther [1]. The exact (simulated) minimum sample sizes were computed and compared with each other and with the corresponding approximated formulas given by Lehmann [2] and Guenther [3]. Numerical results showed that the approximated formulas are very accurate and the Wilcoxon rank-sum test is more efficient when the sample size is more than 45. Otherwise, the Student two-sample t-test is better.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42277387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, there is a dire need to improve medication adherence, particularly among post-liver transplant recipients. Till date, no sufficient data has been published related to our study from Sindh province or even from Pakistan. Therefore, this study will not only help highlight the rate of Medication non-adherence but also implementation of a particular method that could be more helpful to improve the adherence among the study population. The main objective of this study was to determine medication adherence in post-liver transplant recipients before and after text message remainders. A cross sectional study was conducted on 103 post liver transplant patients at Pir Abdul Qadir Shah Institute of Medical Sciences Gambat. BAASIS Scale was used to measure medication adherence among study subjects, after that text messages reminders were given to enrolled patients and adherence was measured again using the same scale to determine the impact of text message reminders on adherence. Among enrolled patients, majority of the study subjects were male, whereas only one participant was transgender. Mostly patients belong to rural areas. Majority of the patients were of matriculation pass, while minorities of the patients were primary pass. Majority of the patients were unemployed, while few had non-government jobs, whereas government job study subjects were in minority. Majority of the patients were of age from 41 to 50, where minority of the patients were aged from 61 to 70. Majority of the patients were prescribed four drugs, whereas no any patient was prescribed only one drug. Majority of the patients were prescribed two immunosuppressant drugs while only few study subjects were prescribed only one immunosuppressant drug. Initially 86% patients were non-adherent to therapy, but after text message reminders, adherence was improved from 24% to 80%. This study concluded that the rate of adherence was improved by giving text message reminders to the patients.","PeriodicalId":15926,"journal":{"name":"Journal of Hunan University Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48280067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
