A change is performed in socially a lot of places by elevations about the quality of life. Most construction balls are created mainly to spaces for an individuality or a specific community, but a space for public convenience is the situation that will gain gradually. While these public space increases, there is a public toilet to an increasing trend too. Think about Cubic Puzzle that it is one total space, and put one function to each Module. The small-scale Cubic space achieves a lot of changes by any energies, and a small-scale space compounds through energies to affect mobile and expansion, and the changed Cubic space does diversification of suitable mobile toilet space configuration to a local need in order to look.

Main objectives of this survey were to find out general sanitary status of water source, draining status and toilet in Shindong Myun, Chungseong Gun. Interviewers of fourteen students visited 1,775 households in this Myun, filled the survey form and checked sanitary conditions of the areas from September 1 to November 30, 1974. Results are summarized as follows: 1. Draining state of pumps is better than that of wells and also the the quality of water sources are better in pumps than in wells. Wells and pumps of 54.1% were constructed more than five years ago. 2. About 66.7% use pump water, 10.5% well water and 8.3% simple piped drinking water system and average water consumption is 22.7l per day per capita. Private water system is 66.0% while public system 27.1%. 3. Water is used for drinking, washing body and cleaning at 53.8% while only for drinking at 7.4%. 4. Nearest pollution sources of drinking water are mainly toilets and stables, and average distances between them are less than ten meters. 5. Toilets of 78.3% are used only by one households and those of 12.9% by two. 6. Toilets of 10.9% are inside main building while those of 85.4% outside main building. 7. Toilet tanks are covered only at 6.3% households while not covered at 95.4%. The contents of tanks are removed about twice a month (40.2%), and 84.1% use them as fertilizer on their own farm and contents of 10.1% are removed by other people. 8. Excreta are utilized on the vegetable farm by 38.2% households, on the vegetable and barley farms by 19.7% and on the paddy fields by 8.2%.

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.

In this study, it was considered that not only the physical form should be electronically copied in virtual reality modeling for real problem solving, but also the interrelationship between the object and the user to be simulated. To this end, a plan was proposed to add user-space interaction elements that occur in real space to virtual reality application. This study is set in virtual reality modeling to solve safety problems in public toilets, and there should be a reasonable principle to add interaction elements with users to virtual reality modeling, and the basic environmental design strategy for crime prevention was used. As a result, it was shown that it was reasonable to derive interaction elements according to certain principles, such as the basic strategy for environmental design for crime prevention.

Purpose : The purpose of this study was to develop an index of usability that reflects the needs and characteristics of the elderly. The usability index is used primarily to assess issues in the usability of a product. Methods : In this study, 22 items for mobile toilet usability index were developed by consulting with 12 elderly users, 6 caregivers, and 12 experts. The usability evaluation index was intended to increase reliability through preliminary and main evaluations. In addition, the validity of the items used as the usability evaluation index was verified to prove that the index is effective for the evaluation. Result : The usability index is a welfare tool developed by gathering data from various sources such as previous studies dealing with usability evaluation, characteristics of users, range of use, and environment of product use. Conclusion : The development of the usability index for mobile toilets was useful for the user to quantitatively derive the problem of the product. Consequently, user needs and usability problems can be identified, which can help improve product quality.

This study was conducted to contribute to the basic data for decisions on environment policy improvement in health promotion, and school sanitation for students in elementary, middle and high schools, by analysing their cognitions and attitudes toward school environmental sanitation. This study was carried out with 1200 male and female students in elementary, middle and high schools in industrial, residential and heavy traffic areas for one month, from July 10 to August 11, 2000. The results of the survey follows. The most serious environmental problems in schools are the toilets, quality of drinking water and the classroom conditions. As for the priority areas for improvement, toilets topped the list followed by the classroom environment, and then by the quality of drinking water. Lack of administrative and financial support, the headmasters' disinterest, lack of interest by the students and parents, lack of awareness among teachers and insufficient effort were cited as the main reasons.

Marine caused pollution occurs mostly near coastal area and its main cause was known to be human feces issued from small vessels. To sterilize liquid pollutants from portable toilets of small vessels, an electrolysis treatment is judged to be the most economic and stable method considering an environment of its use. In this paper, we presents an electrolysis apparatus which is the most appropriate for sterilizing pollutants from portable toilets of small vessels and derives the minimum operating time of the apparatus for sterilizing norovirus which is a main target of marine caused pollution sources. In order to utilize renewable energy, we designed an apparatus which generates a renewable energy from solar cells. As a result, we could confirm the applicability of the proposed system with the results from experiments in three cases of different weather conditions.

This paper presents an improvement method for human body sensing module and management system, specifically focused on the human body detection module with ultrasonic sensors to detect the usage of toilets and the management system to control the state of the toilets of the entire building. The proposed human body sensing module consists of the detection sensor to detect the movement of human body and the contact sensor to detect the position in a certain distance. The management system is configured of the control unit to process the signal transmitted from sensors, opening and closing valves according to the sensing signal, and the short range wireless communication unit to save the operational status data as well as transmit the data at regular intervals.
