This study identifies the ways of utilizing abolition schools and the problems possibly caused by amalgamating small schools in agricultural, mountain and fishing villages. This study aims to find ways to collaborate with the communities based on the characteristics of the districts where schools might be abolished, which can contribute to the development of the society. Following results are integrated by the theoretical framework, social and educational necessities, and analysis of the current situation about the utilization of abolition schools. First, alternative schools, characterized schools, specialized high school can be established as the result of abolition schools that are caused by lack of people in the city. Second, since it is easy for people to access to the agricultural, mountain, and fishing villages near cities, abolition schools in these areas can be used as experience facilities or training places for students and teachers. Third, in case of the abolition candidate schools in the agricultural, mountain, and fishing villages in the districts, students and village people can use the schools for education and social purposes. Fourth, when abolition schools are independently located from the agricultural, mountain, and fishing villages, they can be used as self-service places or local peoples' places for business.

In the domestic housing market, uncompleted lot-solid apartments and unoccupied residences are increasing in the medium-large scale area whose rents and transactions have been unstable, as going through the financial crisis and economical recession. Demands for small-scale housings are steadily increasing by practical consumer group who don't need large places, which are often not needed for the current people who are spending most of their time outside of their houses. Therefore, this study proposes the useful methods for spatial planning for small-scale houses for multiple households, including variable form, levels form, multi-level form, and smart-sizing. For efficient spatial planning for that purpose, here, small-scale housings are not limited to places for families with 1-2 members, but considered as one of broader approaches to graft various households and families. In addition, we examined the existed trends of researches about spatial utility of small-scale places, and did the research about the status of small-scale housing developments, and then proposed the direction for future small-scale housings by analyzing the advanced examples.

The point-of-use water dispenser systems are widely used because of convenience in handling and demand for high-quality drinking water. The application has been increased recently in the public places such as department stores, universities and the rest areas in express ways. Improvement of water qualities by the dispenser systems was compared with tap water in this study. The tap water is supplied to the dispenser as the influent of the dispenser system. The twelve dispensers in the public places were used. The five dispensers used reverse osmosis as the main filter and other dispensers used various filters such as ultrafiltration, nanofiltration, and alumina filter. The water quality indicators for sanitation safety, i.e., turbidity and total coliforms, were evaluated. Other water qualities such as pH, residual chlorine, heterotrophic plate count (HPC), and total cell counts were also analyzed. By the point-of-use water dispenser, the turbidity, residual chlorine and pH were decreased and the HPC and total cell counts were increased. The t-test results revealed that the HPC of the tap waters were not significantly different from the treated waters but the total cell counts of the two groups were significantly different. The low pH of the RO filter treatment was also significantly different from the tap waters. This study will contribute to understand the role of the point-of-use water dispenser in improving water quality and to identify key water quality for the proper maintenance of the dispenser systems.

Background: Conclusive evidence exists about associations between several life-threatening diseases and passive smoking. The objective of our study was to investigate the prevalence of passive smoking among Iranian dental students, to assess their attitudes towards tobacco control programs, and to explore the association between these two and tobacco use. Methods: In eight randomly selected dental schools, all fourth-year students were surveyed by means of a self-administered anonymous questionnaire in December 2010. The Global Health Professions Student Survey (GHPSS) questionnaire served as the data collection instrument. Exposure to environmental tobacco smoke (ETS) was assessed during the previous week. Chi-square test, logistic regression, and linear regression served for statistical analyses. Results: The response rate was 84% (325 students, 66% female). Exposure to ETS was reported by 74% of the participants. Men were significantly more exposed to ETS at home, and in other places than were women. Most of the students agreed on queried tobacco control policies. The lowest agreement (72%) was for banning smoking in coffee shops and teahouses. A logistic regression model showed that adjusted for gender, passive smoking at home is significantly associated with current tobacco use. A linear regression model suggested that the total score of attitudes is significantly associated with passive smoking at home, passive smoking in other places, tobacco use experience, and current tobacco use. Conclusions: The study reports high exposure to ETS among dental students, and its association with current tobacco use and attitudes towards tobacco control.

The world health organization classified the emerging coronavirus (known as Covid-19) as a pandemic after confirming the extent of spread and scale. As a matter of fact, outbreaks of similar scale or even worse have been witnessed throughout history. Thus, the development of prevention strategies exists to protect against such calamaties. One of the widely proven measures that controls the spread of any contagious diseases is social distancing. As a result, this paper will demonstrate the concept of an application "Be Aware" on enabling the implementation of this preventive measure. In particular "Be aware" evaluates the extent of congestion in public places using current time data. The proposed project will use Global Positioning System (GPS), and Application Programming Interface (API), to ensure information accuracy, and the API use Crowdsourcing to collect Real-Time Data (RTD) from the selected places.

The main objective of this research is to analyze an order point and an order quantity of a distribution center and each branch to attain a target service level in multi-level inventory distribution system. In case of product item, we use the item with low volume of average monthly demand. Under the continuous review method, the distribution center places a particular order quantity to an outside supplier whenever the level of inventory reaches an order point, and receives the order quantity after elapsing a certain lead time. Also, each branch places an order quantity to the distribution center whenever the level of inventory reaches an order point, and receives the quantity after elapsing a particular lead time. When an out of stock condition occurs, we assume that the item is backordered. For considering more realistic situations, we use generic type of probability distribution of lead times. In the variable lead time model, the actually achieved service level is estimated as the expected service level. Therefore, this study focuses on the analysis of deciding the optimal order point and order quantity to achieve a target service level at each depot as a expected service level, while the system-wide inventory level is minimized. In addition, we analyze the order level as a maximum level of inventory to suggest more efficient way to develop the low demand item model.
