Today women's social participation is highly increasing, and especially the middle-aged women's activity is amazing. However, many ladies have trouble in wearing suits or jackets. Because the current ready-made apparels focus on young and slender women, and accordingly the current size system is made for them. So it is necessary to develop new size system for general ladies who are hardly well-proportioned figures. The survey of mid-life ladies in this Paper vividly reveals the above Problem. Many ladies dissatisfied with the fitness of the existing apparels. Therefore updating the current size system of ladies' apparels is badly needed. It also helps reducing corporates' stock-holding costs and customer's clothes-adjusting expenses.

Recently, as the global warming by fossil fuels and the steep rise of the oil price become social issues, the interest for renewable energy producing system is increasing rapidly. Among these, the wind turbine is most highlighted because of its economic competitiveness. The tower is one of the main components of wind turbine, which occupying about 20% of overall turbine costs. The tower access door located to base part of the tower, is used to enter the tower. This is the main structural weak points because of door hole, weldment, etc. And so are the weldments between the cans and the flanges. In this study, for the top flange part of the tower, by FEM using ANSYS, we retrieved the maximum von Mises stress on that and carried out fatigue analysis using stresses at such weak points.

Recently, many researches on the biomass of the agricultural and livestock wastes are being conducted in several respects. The use of biomass is of benefit to the curtailment of oil import, environmental pollution decrease, global warming mitigation and so on. And, in the agricultural sphere, making use of agricultural byproducts can contribute to the revitalization of the agricultural industry and rural community. In other words, making new products or energy by using biomass have a possibility to be developed as a new industry. The industry can create new businesses and job opportunities for rural dwellers. Also, major 3 positive effects of market formation for the agricultural wastes, increase of the idle land use and creation of the new business are expected. However, the use of biomass may be difficult to secure a proper right as a market good in the autonomic market economy. It is necessary to establish or amend related laws or systematic tools for the revitalization of the biomass use. Also, it is required for the government to bear partial costs of the facilities and others in the beginning stage.

School closures during the coronavirus disease 2019 (COVID-19) pandemic have been outlined in studies from different disciplines, including economics, sociology, mathematical modeling, epidemiology, and public health. In this review, we discuss the implications of school closures in the context of the current COVID-19 pandemic. Modeling studies of the effects of school closures, largely derived from the pandemic influenza model, on severe acute respiratory syndrome coronavirus 2 produced conflicting results. Earlier studies assessed the risk of school reopening by modeling transmission across schools and communities; however, it remains unclear whether the risk is due to increased transmission in adults or children. The empirical findings of the impact of school closures on COVID-19 outbreaks suggest no clear effect, likely because of heterogeneity in community infection pressure, differences in school closure strategies, or the use of multiple interventions. The benefits of school closings are unclear and not readily quantifiable; however, they must be weighed against the potential high social costs, which can also negatively affect the health of this generation.

Purpose: This study was to identify the attributes, antecedents, their consequences, and empirical indicators of rehabilitation motivation in rheumatoid arthritis patients. Methods: Walker and Avant's method was used to analyze the concept. Articles published after 1990 were searched in Medline, CINAHL, NSDL, and RISS databases using "rehabilitation", "motivation" and their combination as keywords. Results: The attributes of rehabilitation motivation are: 1) certitude and trust toward rehabilitation treatment; 2) confidence in the rehabilitation process; 3) efforts and commitments to achieve health goals; 4) psychological needs to act toward health recovery. Its antecedents include: 1) rights of self-determination; 2) goal setting and goal-oriented attitude; 3) personal needs; 4) getting rewards; 5) social and family support; 6) professional behavior of healthcare providers; and 7) least risks or costs for actions taken. Conclusion: The study results could be used as a conceptual framework for developing tools to measure the motivation of rheumatoid arthritis patients.

Along with rapid global economic development, people are slowly becoming environmentally aware and green development is increasingly a vital topic of social concern. Academic circles are currently focusing on environmental protection and economic growth to explore the coordinated development of both and to achieve a win-win solution between them. To study the relationship between environmental protection experience and both cost and performance, this study empirically analyzes companies listing on the Shenzhen A-share market from 2014 to 2018. The results show that senior executives' environmental protection experience is negatively correlated with corporate costs, whereas it is positively correlated with business performance. These results provide empirical evidence of the importance of enterprises introducing and cultivating environmental personnel and insisting on sustainable development.

This study evaluated the effect of improving the atmospheric environment based on the premise that the supply of hydrogen fuel cell vehicles (HFCV) will be achieved as many as the number of vehicles presented in the hydrogen economy activation roadmap announced by the Korean government in January 2019. The HFCV supply target (2.7 million passenger cars) suggested in the hydrogen economy revitalization roadmap was logically allocated to the five major metropolitan areas in Korea. Air pollution damage costs by region were calculated by reflecting the basic unit of damage cost to the estimated air pollutant emissions. As a result, it was confirmed that the benefits per unit of some cities in Gyeonggi-do were derived more than major cities in the metropolitan area.

Given the different effects of agricultural mechanization on various stages of wheat planting in Henan, this article selects 78 observation samples from Henan, a major wheat-growing province. It uses different research methods (multiple linear regression, social network analysis model, multi-layer sensory nerves network) to conduct a comparative study, and the calculation results of the model show that the experimental results have a strong convergence and consistency. Agricultural mechanization services have significant effects on the three stages of wheat planting: harvesting, plowing and sowing. A higher degree of mechanized service in several stages can reduce the cost of growing wheat on family farms.

The purpose of this paper is to critique the links between science and scientific researchers, politics and capital surrounding vaccines and vaccination in a pandemic era. It also introduces standards for adapting ethical guidelines for research under public health emergencies to specific circumstances and contexts. It also introduces ethical standards to be applied to scientific research. that is, scientific relevance, social value, cooperative partnerships, reasonable risk-benefit costs, fair and voluntary participation, independent review, and equal moral respect for participants and affected communities. It also outlines the COVID-19 (coronavirus disease 2019) pandemic-consent and other research procedure modifications proposed by Oregon Health and Science University (OHSU). We are on the lookout for powerful capital and hegemonic groups inseparable from politics and important decision makers in the pandemic era - that is, scientists, supporters, and scientific civic groups. It underscores the need for an independent and formal scientific advisory body with the right balance between science and politics.
