The toilet in school building is one of most crucial elements for the recent changing face in school design, but the number of toilets and urinals in most school may not be sufficient to meet current needs, especially in the girl's toilet rooms. This study aims to suggest a guideline in designing the toilet in school buildings and propose the optimum area and development of models. The survey for this study is conducted through questionnaires collected and research from 9 schools in Seoul. The results of this study, it is suggested that the number of toilet facilities in school buildings be required by ratio of 0.5 toilets per a class and 1.1 urinal per a class for boy. In case of girls, it is suggested that ratio of 1.6 toilets per a class. Based on the result, it also propose various unit plans for each class block with space such as rest zone, green zone, powder zone etc.

The purpose of this study was to develop satisfaction scale of school toilet that was completed repair work and examine its validity. In order to develop general and scientific satisfaction scale, the data was collected and analyzed targeting 3,694 participants from seventy schools which were elementary, middle, and high schools participating in improvement projects of school toilet in 2015 and 2016. Satisfaction scale of seventeen items was developed by using exploratory factor analysis and confirmatory factor analysis. Total Cronbach's ${\alpha}$ of seventeen items resulted in .950. Factor loading indicated over 0.6. Factor explanation of each item showed that was relatively high. This scale can be used to research unit school satisfaction and utilized for further research. The implication of this study was a reliable and valid instrument for measuring the satisfaction of school toilet.

Educational Facility has a specialty that similar design is repeatedly taken place so the importance of POE(Post Occupancy Evaluation) is increased for the improvement of problem appeared at the former projects. The POE could provides help to the design of next project and the direction when the need of remodeling is faced. Through the process of POE, the repeat of design mistakes could be prevented and the good information related with building efficiency and other problems could be applied to the design of next school project . In this study, the POE of Manbalro(barefoot) toilet of D Elementary school in rural area of H county is performed. The toilet is renovated as an educational environment improvement project of H county educational office in Chungcheong Namdo Province. The study is focused on the user's behavior at Manbalro toilet for carrying out indicative POE by the subjective response of user's. From the research, several being reformed items is proposed however the toilet is evaluated as a successful project that design purpose of initial stage is applied well.

Although the improvements in the health sanitary facilities of the elementary school were made by the implementation of the 7th curriculum, color design and concept of toilets used by lower classes students were shown to be still insufficient and so, it is also necessary to have color planning for toilets considering users' preferences. This study is targeting lower classes children of elementary schools under Seoul Gangseo Office of Education. The purpose of this study is to propose a toilet color design direction preferred by children as users. Therefore, the toilets of elementary school were investigated and at the same time, juvenile pictures were analyzed. The results of this study are that the color space used in the current design, the following gives a substantial psychological and emotional impact for many elementary school children in the developmental stages of children leads to an interesting use of color. Therefore, this study propose to improve the toilet to a more familiar environment with high accessibility considering the development of the child when using color in design space through color preference.

The application of appropriate technologies in a developing country is an opportunity to introduce green technology which may lead people to imagine a better life. This point is at the intersection of appropriate technology and sustainable development. This research focuses on Hatphain village where there is no clean water, sewage system, or power lines. Two environmental technologies (an unpowered water purification system, Ongdalsaem and an eco-toilet system, BeeVi toilet) were introduced, based on the concepts of the environmental self- sustainable village and feces Standard Money (fSM). We found that the Ongdalsaem was effective in reducing the concentration of nitrogen and lead in the water in Hatphain. The BeeVi water-free toilet was installed, allowing urine and feces to be separated and used as compost. We strived to spread ideas of sustainability using new eco-circulation experiences and encouraging learning about environmental technology through practical and playing facilities that residents managed themselves.

The amount of water resources that can be used tend to be decreased gradually. In contrast, the rapidly increasing water consumption is a problem that need to be addressed. Renovation and equipment replacement to improve energy efficiency and to reduce expenditure for building usage is required. But the excessive initial investment cost and the prolonged of pay back period may be uneconomical choice. Water usage for cleaning the toilet bowl accounts for 27%of the total water usage. Water-saving valve that can select the amount of water for cleaning toilet bowl can be reduced expenditure. After installing water-saving valve, analysed the economic effects. Water-saving valves compared with flush valves, and researched the amount of water usage. Then analyzed for the economic effects. Water-saving valve was used 5.6 ${\ell}$/time for cleaning toilet bowl. In contrast, flush valve was consumed 8.4 ${\ell}$/time. Water-saving valve's water-saving rate was 33.3%. The initial payback period for Water-saving valve was 459.5 days. By a small investment in water saving valve, the economic benefits can be obtained.

Elementary school's physical environment is critical to lower grade students. Among the many physical conditions, Toilet, which belongs to health and sanitation category is very important to those who start school for the first time. The purpose of this study is for suggesting the guidelines of toilet design reflecting psychological and behavioral aspects of lower grade students. The research was executed as follows. Firstly, focused survey groups were carefully chosen. Five elementary schools were selected, being all open after 2005 under Seoul Gangseo District Office of Education. Secondly, field study was executed to find out toilet usage, during the period between April to June 2012, by visiting schools to see basic facilities, taking pictures and making actual measurement in each toilets. The architectural analysis was focused on location, moving line, actual size and space zoning, while the interior analysis being on finishing materials and the design of sanitary equipments. And the design elements such as color, lighting fixture, art works or signage were analysed, too. Finally, questionnaire survey was done to find out preferences of lower grade students. As a result, the guidelines of toilet design can be divided into two main parts, Physical and Psychological. For the Physical part, it is necessary for related facilities to be concentrated in order to give easy access. In addition, good ventilation, better lighting and to install sanitary equipments ergonomically are required. Furthermore, safe and clean maintenance should be considered. Psychologically, the design should be directed for making lower grade students come to toilets with comfort and more pleasantly.

물 부족 시대에 양변기 절수는 물을 절약하는데 가장 효과적인 방법 중 하나이다. 본 연구에서는 고절수형 양변기 개발을 위한 이상유동 해석을 위해 VOF 기법을 이용하였다. VOF를 이용한 전체 모델의 해석은 많은 시간이 요구되므로 전체모델의 일부분만 고려하는 부분모델도 해석시간 단축을 위해 사용하였다. 유량배분 해석을 위해 4개의 서로 다른 림 모델을 고려하였는데 림 홀의 위치나 개수보다는 림 홀의 크기가 유량배분을 효과적으로 달성하기 위한 인자임이 본 연구를 통해 밝혀졌다. 또한, 전체모델 해석을 통해 사이펀 현상에 따른 이상유동의 속도 및 압력도 분석하였다. 따라서 본 연구는 고절수형 양변기 모델 개발을 위한 다양한 기초 데이터를 제공한다.
