Driving behavior questionnaires (DBQs) are widely used in driving research. 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.
驾驶行为问卷(DBQs)在驾驶研究中得到了广泛的应用。世界上一些国家对该规模的支持褒贬不一。因此,本研究在尼日利亚商业卡车司机的大样本中检验了司机行为问卷(DBQ)的有效性和可靠性。采用结构方程建模方法分析复合信度和结构效度(平均方差提取(AVE)和异性状-单性状比)。作者发现,构念的复合信度、收敛效度和区别效度分别大于0.7、0.5和小于0.9,表明构念对尼日利亚货车司机样本是有效和可靠的。该结果的新颖之处在于,驾驶员行为问卷可以用于研究尼日利亚商用卡车驾驶员实现RTA减少的行为,从而获得一致和有效的结果。

The study is based on the descriptive experimental method, where the research deals with the creation of a new type of surface insulator and its use as a heat insulator, where the remnants of fabrics and threads are used with paper pulp of different thicknesses to determine the extent of their ability to heat insulation. 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.
这项研究基于描述性实验方法,研究涉及一种新型表面绝缘体的制造及其作为隔热材料的使用,将织物和丝线的残余物与不同厚度的纸浆一起使用,以确定其隔热能力的程度。两位研究人员制备了厚度为3厘米-2厘米-1.5厘米的非织造布研究样品。研究目标是强调回收纱线和织物残留物在反射紫外线、隔热方面的作用,并确定获得最高隔热效果的最合适厚度。结果是用热方技术的热导率计获得的。根据所使用的厚度,样品的导热系数的值存在差异。样品的厚度越高,导热系数越低,因此隔热值越高。研究中的样品的导热系数结果通常非常低,这表明样品在很好地隔离表面方面取得了成功,因为该值在0.032和0.0178之间。从这里开始,使用空调设备和高价绝缘体可以节省纸张和织物的材料。这是两位研究人员为节省电力消耗而进行的尝试,当空调在高温地区长时间使用时,电力消耗会增加。

This research intends to evaluate the risk-level change of dam break due to the number of population growth rates in the dam downstream. 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.
本研究旨在评估大坝下游人口数量增长率对溃坝风险等级的影响。大坝下游地区的人口增长率决定了受灾害风险影响的人口数量。在本研究中,根据种群增长率的增加数量对溃坝进行了危险等级的划分。在本研究中,根据人口增长率的增长对溃坝进行了分类。该方法从数据收集开始,例如用于分析大坝溃坝的PMF设计洪水,获得大坝下游地区的洪水边界,用于了解大坝下游地区地形的数字高程模型地图,从BPS获得的人口数据,用于了解人口增长率,从而可以预测人口数量,直到水库寿命;而土地利用数据则是为了了解下游坝区的人口增长率,从而了解到水库寿命期间的居住发展情况。然后根据风险人群的数量进行评价和评估。结果表明:滨塘巴诺坝、罗蒂克洛特坝、纳蓬盖特坝、洛拉克坝、库威尔坝、潘度杜里坝等6座大坝下游破坏程度危险性极高,分级评价极值;然而,其他四座大坝也显示出非常高的危险水平,但在大坝的评估分类中是高的(不是极端的),如Batu Nampar, Kengkang, Sepit和Jangkih Jawa大坝。以期对水库全寿命期溃坝危险性分级进行预测。此外,还可以为决策者确定溃坝风险等级提供参考。此外,它还可以作为建立溃坝风险分类模型的输入之一。

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.
医疗保健领域的物联网(IoT)是医疗保健市场的最新趋势。物联网使医疗保健提供者能够将其覆盖范围扩展到通常的临床环境之外。他们致力于最大限度地发挥数字链接医疗保健服务的可能性,以改善用户体验、诊断准确性和医疗保健专业人员之间的沟通。传感器、可穿戴设备和健康监测仪使医疗保健变得更便宜、更快、更有效。尽管物联网在医疗服务中享有特权,但这些服务的采用率仍处于早期阶段。这项研究的目的是检查马来西亚慢性病患者采用物联网医疗服务的情况。为了实现这一目的,该研究提供了一个综合框架,以调查已确定的因素对采用物联网医疗服务的行为意向(BI)的影响。新颖之处在于结合了技术接受和使用的统一理论(UTAUT)、技术采用的组织环境理论(TOE)和社会交换理论(SE)。一项在线调查的对象是马来西亚的慢性病患者。使用偏最小二乘结构方程模型研究了11个预测结构的影响。研究结果显示,个人和技术因素及其维度显著影响慢性病患者对物联网医疗服务采用的BI。BI对使用行为(UB)的影响也观察到了类似的结果。同时,信任在一定程度上介导了个体和技术相关因素对BI的影响。

In Morocco, the rate of people affected by psychological and mental disorders is increasing every year, especially in the school environment. 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.
在摩洛哥,受心理和精神障碍影响的人数每年都在增加,尤其是在学校环境中。这对国家的发展、人口的提升以及他们在社会中的盈利能力产生了负面影响,摩洛哥现有的个人护理中心稀缺就是原因。这项工作旨在总结有关儿童、青少年和其他患有心理障碍的人的帮助中心的文献。我们进行了一项比较研究,这是一种非常富有成效的方法,包括通过比较每个引用国家之间的一般标准,对非洲(如摩洛哥)、欧洲(如法国)、美国(如加拿大)和美国的护理中心形式进行比较。结果表明,英语模式是最成功的,可以作为摩洛哥背景下的一种模式。根据这项科学研究的结果,很明显,有必要引入美国模式使用的标准:年龄类别和多学科团队,因为它们代表了最成功的医疗中心的支柱。总之,医疗保健中心的正确管理需要所有现有模式的干扰,同时利用每种经验的优势和局限性。

Mobile edge computing offers cloud-like services at the edge of mobile networks to fulfill the escalating user demands for applications that are latency sensitive and require quick computation. 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.
移动边缘计算在移动网络的边缘提供类似云的服务,以满足用户对延迟敏感和需要快速计算的应用程序不断增长的需求。然而,这种模式仅限于有限的资源;因此,为了实现资源的最优利用,需要一种高效的资源配置策略。考虑到这一事实,本文旨在描述一种新的方法,即基于优先级的资源分配方案,以有效地利用该范式中的可用资源。通过考虑传入请求的时间约束特性,自适应地分配计算资源。建议的方法应适应完成任务所需的资源和收到的请求的优先次序。在确定接收到的请求类型(可以是基于优先级的请求,也可以是普通请求)之后,将以三种可能中的一种处理每种请求。在边缘节点,可用资源的管理方式是处理最大数量的传入请求和最优地使用稀缺资源。仿真结果表明,我们提出的基于优先级的资源分配方案在平均响应时间、平均延迟、资源使用、任务执行时间分析和能耗等方面都优于基准方案。

Experimental Comparison of the Sample Sizes of the Two-Sample Tests of Wilcoxon and Student under the Arcsine Distribution 反正弦分布下Wilcoxon和Student两样本检验样本量的实验比较

When statistical experiments are performed, a sample size should be chosen in some optimum way so that we should use a sample size no larger than necessary. 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.

当进行统计实验时,应该以某种最佳方式选择样本量,这样我们就应该使用不超过必要的样本量。本文比较了正弦分布下两样本t检验和Wilcoxon秩和检验的最小样本量,基于它们的幂[1,2]。为了完成这项任务,作者推导了一些在Wilcoxon秩和检验的幂和样本量确定中有用的基本概率,用于计算Lehmann[2]给出的近似公式。使用复合数值积分算法来计算这些概率,这些概率与反正弦分布有关。在这项研究中,作者建立了一个计算机程序,通过对n进行迭代,找到任何有效水平和幂的精确(模拟)最小样本量n,n的起始点由[2,3]的近似公式提供。这篇研究论文的科学新颖性在于,通过考虑一组新的正弦分布移位替代方案来确定最小样本量,该替代方案将位移分布的左端作为第二分布的p阶分位数,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":" ","pages":""},"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}

Non-adherence among post liver transplant recipients may lead to serious consequences. 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.
肝移植后受者的不依从性可能导致严重的后果。因此,迫切需要提高药物依从性,特别是在肝移植后受者中。到目前为止,没有来自信德省甚至巴基斯坦的与我们的研究相关的足够数据发表。因此,本研究不仅有助于突出药物不依从性的比率,而且还有助于实施一种更有助于提高研究人群依从性的特定方法。本研究的主要目的是确定肝移植后受者在短信留言前后的药物依从性。在甘巴特Pir Abdul Qadir Shah医学科学研究所对103名肝移植后患者进行了横断面研究。使用basis量表测量研究对象的药物依从性,然后向入组患者发送短信提醒,并使用相同的量表再次测量依从性,以确定短信提醒对依从性的影响。在登记的患者中,大多数研究对象是男性,而只有一名参与者是变性人。大多数患者来自农村地区。大多数患者为预科合格,少数患者为初级合格。患者以失业居多,有非政府工作的较少,而政府工作研究对象占少数。患者年龄以41 ~ 50岁居多,61 ~ 70岁为少数。大多数患者都开了四种药,而没有患者只开了一种药。大多数患者使用两种免疫抑制剂,只有少数研究对象只使用一种免疫抑制剂。起初,86%的患者不坚持治疗,但在短信提醒后,依从性从24%提高到80%。这项研究的结论是,通过给病人发短信提醒,依从率得到了提高。
