Based on the relevant studies of lean production, production technology improvement, quality management and production performance, the relationship model of lean production, production technology improvement, quality management and production performance of high-tech manufacturing companies is constructed, and the influence mechanism of lean production and production technology improvement on production performance of high-tech manufacturing companies is revealed. Specifically, by systematically reviewing relevant theories and existing research results, this paper proposes a logical idea of “lean production, production technology improvement — quality management — production performance”, discusses and proposes relevant research hypotheses according to the relationship between variables in the theoretical model, and sends out questionnaires to Chinese high-tech manufacturing companies on a large scale, and recovers 425 questionnaires. The incomplete or invalid questionnaires with obvious errors were eliminated, and 411 valid questionnaires were finally obtained. The statistical analysis software SPSS 24.0 and AMOS 24.0 were used for reliability analysis, validity analysis, exploratory factor analysis, typical correlation analysis of the collected data, multiple linear regression analysis model and mediation effect model was established. Test the theoretical paper. In this paper, a total of 7 research hypotheses are proposed, among which 7 hypotheses are supported by the survey data. Combining qualitative analysis and quantitative analysis, this paper draws the following conclusions: (1) Lean production has a significant positive impact on the production performance of high-tech manufacturing companies; (2) The improvement of production technology has a significant positive effect on the production performance of high-tech manufacturing companies; (3) Quality management has a significant positive effect on the production performance of high-tech manufacturing companies; (4) Quality management has a partial mediating effect between lean production and production performance of high-tech manufacturing companies; (5) Quality management plays a partial mediating role between production technology improvement and production performance of high-tech manufacturing companies.

The paper aims to investigate the extent to which urbanization and industrialization affect bank development in the WAEMU (West African Economic and Monetary Union). To meet the goal of this study, we used the Pooled Mean Group (PMG) estimator, which requires long run coefficients to be similar but allows short run coefficients and error variances to fluctuate among groups. The sample of the study is composed of 7 countries, with Guinea-Bissau excluded, due to the absence of data on the period from 1980-2016. The results revealed that urbanization has a positive effect on banking development in the WAEMU. This intuitive relationship is linked to the fact that, as the urban population grows, the relative demand for financial services also grows. Also, industrialization has a good impact on banking development. In terms of policy implications, the study calls on governments to create the necessary conditions for successful urbanization to benefit the development of banks in the WAEMU zone.

It has been self-evident that consumers are essential stakeholders in companies, and their satisfaction is management’s top concern. In recent years especially during the COVID-19 pandemic, the usage of online food delivery applications has drastically increased along with the embracement of new technologies in almost every corner of Bangladesh. Thus, with increased competition in the market, quality of service has become an essential aspect of customer satisfaction. Considering the hazard of COVID-19, the World Health Organization (WHO) strictly emphasizes on maintenance of hygiene along with other guidelines. The relationship between customer satisfaction with hygiene factors has been confirmed by some researchers, although few studies have been conducted solely on the topic. This descriptive research aims to identify and examine the relationship between customer satisfaction and hygiene factors while ordering food online during COVID-19 in Bangladesh. A combination of simple random sampling under the probability sampling techniques and snowball sampling under the nonprobability sampling techniques has been used to collect quantitative data from customers of Dhaka city. Reliability tests, Multiple regression analyses, and Pearson correlation have been conducted with the help of SPSS to analyze the data. Findings suggest that hygiene factors should be prioritized to ensure customer satisfaction. Quality of food and packaging of food has been found to be two of the most important variables under hygiene factors from this study. It has provided results that could be useful to managers and employees in the online food delivery industry for strategic planning and to achieve a sustainable business model.

This article examines the statistical results for several African nations. The country with the highest migration rate in east Africa is Sudan, where there are about 0.24 million migrants every year. Seychelles has the fewest migrants, with only 5,000 people. Tanzania, Kenya, and Uganda are the countries that get the most donations. South Africa is the nation in the South African area that receives the highest levels of emigration and remittances, with an emigration rate of 0.13 million and repatriated profits of 489.6 million US dollars. In Botswana, transfers and emigration are at their lowest levels. In our statistical analysis, the Hotelling test statistic shows the population mean vector with migration and remittances for various countries in East Africa, South Africa, and West Africa. It produces statistically significant results at the 5% level in MANOVA analyses for the equality of means test for the nations of all three regions. To construct a panel regression model on the data, the data analysis was assisted by the LM test statistic and a fixed-effect model. Panel data analysis can help identify the yearly average number of migrants and the amount of remittance in different respected regions. Migration has a significant impact on remittances, and the inability of time-series migration data to be time-series migrated is one of the study’s main constants. One can use a simulation study to get fruitful results.

The banking industry is essential to supporting other institutions and general economic development in sub-Saharan African countries, acting as a vital support system for other institutions and overall economic development. This research aims to examine the correlation between banking sector assets, bank deposits, and liquid liabilities and their implications for the economy. A comprehensive survey was conducted, targeting all commercial banks in South Sudan. The questionnaire was completed by 50 directors, managers, and senior officers. The findings showed a tenuous inverse link between consumer deposits and economic expansion. To address these concerns, it is imperative for the government to establish a stable political system, exercise fiscal discipline, and establish effective information infrastructure within the banking sector. Policymakers should also prioritize tackling tax evasion and avoidance to bolster bank profitability and effectively deal with the challenges faced by the economy.

Project management has become more difficult due to shifting consumer demands and technical development. Recognizing the benefits of high-performing project teams in delivering effective project outcomes is critical. This research examines the advantages of enhancing team skills in industries where people collaborate to achieve common goals. A thorough analysis of the research on project management strategies, team dynamics, and skill development was carried out. Additionally, empirical data was gathered through surveys and interviews with influential businesses' senior executives. The study showed a significant link between team skills and project performance. The statistical analysis of the survey data supported the premise that investing in team skill development significantly adds to project performance. The findings clarify that improving team skills should be regarded as a core project management technique. Team skills is essential for departments and cross-functional teams to perform effectively in businesses of all sizes. Organizations can foster a culture of continuous improvement, flexibility, and innovation by implementing various strategies such as training workshops and agile project management techniques. According to the study, prioritizing team skill development is crucial for maintaining a competitive advantage and effectively navigating the always-changing problems in businesses. Industry stakeholders should understand the need for technical proficiency and soft skills within project teams as project complexity rises.

A healthy urban environment depends heavily on effective waste management. Recently, a large number of city/urban areas have sprung up in Bangladesh, where daily production of solid waste is rather high. Rangpur City Corporation (RpCC) is a recently built city with 33 wards in the northern region of Bangladesh. Only 15 of them out of the total practice solid waste management. The essential area of RpCC is covered by these 15 wards. This study aims to detail the solid waste management procedure as well as the current state of various garbage dumping locations inside the research region. In order to evaluate and keep track of the trash dumping places, the primary data was directly gathered via field survey in order to assess and monitor the waste dumping points. Besides, additional data/information were collected from books, journal, and websites. This study suggests the lean tool kanban and visual management to keep the solid waste management process standard and keep on the road of continuous improvement. Kanban is very helpful to avoid breakdown of solid waste management process. On the other hand, visual management also can take a part to make the solid waste management easier and more helpful to avoid any fault in this process by its implementation.
健康的城市环境在很大程度上取决于有效的废物管理。最近，孟加拉国出现了大量的城市/城市地区，那里每天产生的固体废物相当高。Rangpur City Corporation (RpCC)是最近在孟加拉国北部地区建立的一个拥有33个区的城市。其中只有15家实行固体废物管理。这15个区涵盖了警协的基本区域。本研究旨在详细介绍研究区域内的固体废物管理程序以及各垃圾倾倒地点的现状。为了对垃圾场进行评价和跟踪，通过实地调查直接收集原始数据，对垃圾场进行评价和监测。此外，还从书籍、期刊和网站上收集了额外的数据/信息。本研究建议使用精益工具看板和可视化管理来保持固废管理过程的标准，并保持持续改进的道路。看板对于避免固体废物管理过程的崩溃非常有帮助。另一方面，可视化管理也可以起到一定的作用，使固体废物管理更容易，更有帮助，避免在这一过程中出现任何错误。

The main aim of this research is to figure out how fundamental and macroeconomic factors affect stock returns in Bangladesh. Five companies out of seven that are listed on the DSE and are part of the cement industry were randomly selected for this purpose. The companies involved are Heidelberg Cement Bangladesh Limited, Lafarge Holcim Bangladesh Limited, Premier Cement Mills Limited, Crown Cement PLC, and Meghna Cement Mills Limited. All the data were gathered as time series on a monthly basis, spanning the years 2012 through 2021. For the sake of the study's objective, some fundamental and macroeconomic factors are identified and incorporated into the framework of multiple regressions. In addition to these fundamental factors, which include debt to equity, return on asset (ROA), return on equity (ROE), price earnings (P/E) ratio, and earnings per share (EPS), macroeconomic factors, e.g., inflation (INF), gross domestic product (GDP), interest rate (INT), money supply (M2), foreign direct investment (FDI), and exchange rate (EX), are also considered. According to the study's overall findings, among key variables, Lafarge Holcim Bangladesh Ltd. and Heidelberg Cement Bangladesh Limited both had positive and statistically significant EPS and PE ratios, whereas Crown Cement PLC only had a positive and statistically significant PE ratio. However, only inflation was determined to have a negative and statistically significant effect on Meghna Cement Mills Ltd. among all sample companies. None of the fundamental or macroeconomic factors was found to be statistically significant in the case of Premier Cement Mills Limited. Since it includes a wide range of macroeconomic variables in addition to the selected fundamental variables, this study stands out from others for listed firms within the cement industry of DSE, Bangladesh. Such a study would be more beneficial if it took into account more exogenous variables and stocks that are listed in or outside of this sector. This study's entire data analysis was carried out with the use of the statistical software Eviews version 10.
本研究的主要目的是弄清楚基本面和宏观经济因素如何影响孟加拉国的股票回报。为此，在首尔证券交易所上市的7家水泥企业中，随机抽取了5家。涉及的公司包括海德堡水泥孟加拉国有限公司、拉法基豪瑞孟加拉国有限公司、Premier水泥有限公司、Crown水泥有限公司和Meghna水泥有限公司。所有数据都是按月收集的，时间跨度从2012年到2021年。为了研究的目的，确定了一些基本因素和宏观经济因素，并将其纳入多元回归的框架。除了这些基本因素，包括债务股本比、资产回报率(ROA)、股本回报率(ROE)、市盈率(P/E)比率和每股收益(EPS)之外，宏观经济因素，如通货膨胀(INF)、国内生产总值(GDP)、利率(INT)、货币供应量(M2)、外国直接投资(FDI)和汇率(EX)，也被考虑在内。根据研究的总体结果，在关键变量中，拉法基豪瑞孟加拉国有限公司和海德堡水泥孟加拉国有限公司的每股收益和市盈率均为正且具有统计学意义，而皇冠水泥有限公司的每股收益和市盈率仅为正且具有统计学意义。然而，在所有样本公司中，只有通货膨胀被确定对Meghna Cement Mills Ltd.具有负的和统计显著的影响。在Premier Cement Mills Limited的案例中，没有发现任何基本面或宏观经济因素具有统计显著性。由于它包括广泛的宏观经济变量除了选择的基本变量，本研究从其他的水泥行业内的上市公司DSE，孟加拉国脱颖而出。如果考虑到更多的外生变量和在这个部门内外上市的股票，这样的研究将会更有益。本研究的全部数据分析使用统计软件Eviews version 10进行。

Five companies out of seven that are listed on the DSE and are part of the cement industry were randomly selected for this purpose. The companies involved are Heidelberg Cement Bangladesh Limited, Lafarge Holcim Bangladesh Limited, Premier Cement Mills Limited, Crown Cement PLC, and Meghna Cement Mills Limited. All the data were gathered as time series on a monthly basis, spanning the years 2012 through 2021. For the sake of the study's objective, some fundamental and macroeconomic factors are identified and incorporated into the framework of multiple regressions. In addition to these fundamental factors, which include debt to equity, return on asset (ROA), return on equity (ROE), price earnings (P/E) ratio, and earnings per share (EPS), macroeconomic factors, e.g., inflation (INF), gross domestic product (GDP), interest rate (INT), money supply (M2), foreign direct investment (FDI), and exchange rate (EX), are also considered. According to the study's overall findings, among key variables, Lafarge Holcim Bangladesh Ltd. and Heidelberg Cement Bangladesh Limited both had positive and statistically significant EPS and PE ratios, whereas Crown Cement PLC only had a positive and statistically significant PE ratio. However, only inflation was determined to have a negative and statistically significant effect on Meghna Cement Mills Ltd. among all sample companies. None of the fundamental or macroeconomic factors was found to be statistically significant in the case of Premier Cement Mills Limited. Since it includes a wide range of macroeconomic variables in addition to the selected fundamental variables, this study stands out from others for listed firms within the cement industry of DSE, Bangladesh. Such a study would be more beneficial if it took into account more exogenous variables and stocks that are listed in or outside of this sector. This study's entire data analysis was carried out with the use of the statistical software Eviews version 10.","PeriodicalId":297563,"journal":{"name":"International Journal of Science and Business","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130332508","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}
