However, the uptake of HCT has been very slow globally, especially in sub-Saharan Africa. Student nurses formed the largest group undergoing health care training in the country compared to doctors and other health cadres. According to WHO, they are part of the most vulnerable group to HIV infection, judging by the fact that they interact more with patients/clients than other healthcare professionals. This study aimed to determine the prevalence of HCT uptake, knowledge, and attitude and evaluate influencing factors among student nurses and midwives in public nursing schools. An institutional-based cross-sectional study design was employed to collect data from 305 randomly selected nursing students and midwives using a validated and reliable self-administered questionnaire. Descriptive statistics (percentages, mean and standard deviation) and inferential statistics (chi square, logistics regression, one-way ANOVA and independent samples t-test) were used for data analysis using SPSS version 25.0. A p-value < 0.05 was considered for statistical significance. Out of the 305 students recruited for the study, 60.98% were females, with a mean age of 25.5 years old. About 58.4% of the participants had tested for HIV in the past. About 95.7% acknowledged the importance of HCT in the prevention and control of HIV/AIDS. HCT uptake among student nurses and midwives was influenced by factors ranging from an individual that are interpersonal challenges (such as concerns of friends), perceived susceptibility to the disease, lack of confidentiality, stigma and discrimination from health service providers. Therefore, these barriers can be addressed through an organized targeted health education intervention and advocacy programs across health training institutions in the Gambia and beyond.","PeriodicalId":227013,"journal":{"name":"Journal of Management Science & Engineering Research","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133979964","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}

In several cases the data are exponentially distributed: we see how to scientifically deal with Control Charts (CC) to decide; this is opposite to what gives the T Charts that are claimed to be a good method for dealing with “rare events”: The Minitab Software (19 & 20 & 21) for “T Charts” is considered. The author will compare some methods, found in the literature with the author’s Theory RIT (Reliability Integral Theory): We will see various cases found in the literature.

The novelty of the paper is in the scientific way of dealing with the Control Charts and their Control Limits, both with normally distributed data and with exponentially distributed data.

When the apparel market and corporations focus on environmentally friendly products, Bangladesh’s textile and apparel sectors remain far behind, putting the country at risk of losing market share. It is right of passage to implement techniques and a long-term strategy to sustainability. Bangladeshi apparel industries are currently facing significant issues in terms of labor conditions. In garment manufacturers, fires are a common occurrence. Thousands of workers have perished because of these dangers. Due to Bangladesh’s fire and safety difficulties, several foreign purchasers have already opted not to do business with the country again. Furthermore, workers receive the world’s lowest pay, which leaves them dissatisfied and frequently results in conflicts and violence during protests poor wages. This study is conveyed based on theoretical, analytical, and statistical aspects. The goal of this study is to represent the overall picture of sustainability in the apparel industry in Bangladesh. This study illustrates on using a life cycle approach to assessing manufactured products for environmental indicators to attain sustainability, fast fashion, government policy of sustainability, new method and material of garments and compare with the lifestyle of Europe against Bangladesh.

Balai Pengujian & Sertifikasi Mutu Barang Makassar is a government agency operating in South Celebes that tests the quality of various agricultural and plantation commodities. From year to year, demand for testing services has increased along with the number of exports. So, testing activities have changed in terms of facility layout requirements resulting in overwhelmed in carrying out the testing process. Test rooms are not connected based on the current testing flow causing the tester’s ineffective work patterns. This study aims to redesign the layout of the facilities in the testing laboratory with the Kaizen approach to support the smooth testing process. The results of this study indicate that the proposed floor area uses a 150% allowance so the calculation requires a floor area of 42.52 m2 . After that, an analysis of the proximity of the facilities is carried out by making ARC (Activity Relationship Chart) and ARD (Activity Relationship Diagram). Based on ARD, a template is made for the layout of testing laboratory facilities.

Coarse aggregates were replaced with e-waste plastic in concrete at 5%, 10%, 15%, and 20% for a concrete class of C20. The particle size distribution of the e-waste plastic aggregates was determined as well as the slump, compressive strength, water absorption and bulk density of the concrete. Generally, the slump decreased as the e-waste increased. The compressive strengths decreased for the 5% and 10% replacement of coarse aggregates with e-waste but increased for the 15% and 20% replacement of coarse aggregate with e-waste. 0% water absorption was obtained for the 15% and 20% e-waste content while the 10% e-waste concrete obtained 0.01% and the 5% e-waste obtaining of 0.013% after 28days of curing. The densities of 5%, 10%, 15% and 20% e-waste plastic content decreased as compared to the 0% e-waste plastic content. The values of compressive strength obtained showed that coarse aggregate replacements by e-waste plastic at 15% and 20% may be appropriate for lightweight concrete of class C20/25 since compressive strengths ranged between 16.09 Nmm–2 and 22.87 Nmm–2. This implies that partial replacement of coarse aggregate with e-waste plastic may be useful for lightweight concrete as well as helping in eradicating the environment of the menace of e-waste plastic.","PeriodicalId":227013,"journal":{"name":"Journal of Management Science & Engineering Research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124044867","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 availability and quality of spare parts are key elements of this strategy while ensuring minimal management costs. The reuse of spare parts retrieved from customer systems is a growing maintenance strategy practice which impacts the traditional spare parts supply chain. This reuse is primarily driven by extending the economic life of goods, initially regarded as waste and therefore without added value, by transforming them into valuable spare parts that can be reused; secondly, for environmental or regulatory reasons, demanding responsibility for the treatment of products at the end of their life; and thirdly, to improve the availability of parts for maintenance, especially parts that the organization can no longer purchase or that are impacted by other issues. It also involves the analysis of their condition and their eventual return to working order as they are retrieved from the customer’s systems in a defective condition.

So that it needs to practice a continuous revision or update periodically for realistic estimation of costs and benefits. This paper presented the relationship and comparison between road users’ cost along Addis Ababa-Adama newly constructed expressway using the Highway Development and Management (HDM-4) Software and manually using formulations developed in the Portuguese model. The method started with data collection. All input data were collected from primary and secondary sources. The primary data utilized an interview, and secondary data were sourced out from pertinent documents, both published and unpublished. More data were gathered that related to vehicles. The vehicles using the road are classified based on the manual from the Ethiopian Road Authority as cars, utilities, small bus, large bus, small truck, medium truck, heavy truck, and truck trailer. The collected data have been input into the HDM-4 interface; the output of the analysis was vehicle operating costs, travel time, and road users’ cost as a summation. Using manual technique and HDM-4 Software, Birr 128.62/km/vehicle and Birr 139.23/km/vehicle, respectively, were found from road users’ costs analysis. The result shows the difference of Birr 10.61. Also, the correlation coefficient of 0.75 is determined, which shows that the two results of road users’ costs are highly related. As a result, the study reveals that the application of HDM-4 Software and the manual technique formulations from the Portuguese model can be adopted interchangeably to calculate Road Users’ Cost of road sections in Ethiopia. Hence, the study results are expected to be an eye-opener for a future similar project by the concerned agencies.","PeriodicalId":227013,"journal":{"name":"Journal of Management Science & Engineering Research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122314135","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}
