The Restroom in house have a main role of bath, excretion, and washing hands. So there are usually bathtub, washbasin, and chamber pot. But the actions of bathing, excretion, and washing hands are not always occur at the same time. So the necessary of sectioning the restroom's space is introduced. In Japan they have some different methods in planning the restroom space. They separate the roles of bathroom and toilet, and develop several types of restroom. And they applicated the several types of restroom to appropriate spaces and floors. These sectioning the restroom's space make the moving line rational and take off the waste of spaces.

The fire on a high-rise building would possibly cause fatalities because of ineffective egress due to extended evacuation distance in huge building structure, coupled with dense population, thus requiring secured optimal evacuation method and space. The restroom located in the living space is considered to be useful refuge space which is built with wet pipe and noncombustible materials. This study aimed to develop a system that would make use of the existing restroom as a fire refuge space. Ventilation duct were installed to discharge odor during normal conditions. We could serve the air supply duct to also raise the air pressure in the restroom so as to prevent the toxic gas from gapping around the restroom. The nozzle for the water screen would be installed in restroom door facing the living room to form the water screen which would protect the door. This study is intended to replace the existing refuge space with the restroom in such a way as described above.

This study measured radioactive surface contamination in general public restrooms in hospitals and in dedicated toilets for nuclear medicine. The measurement method was measured using Berthold (LB 124, Germany) at the entrance to the restroom, inside the restroom, around the restroom, in the urinal, and around the urinal. As a result of the use of the restroom, there was no dedicated place waiting for patients who received radioisotopes in one of the three hospitals. As a result of measuring the restroom for exclusive use of radioisotopes, all measurement sites in the radioiodine therapy room were the highest, and the results of measuring the public restrooms showed background level contamination at all hospitals except hospital B. However, it was measured as 8.073 Bq/㎠ and 6.426 Bq/㎠ in the urinals in the public restroom on the first floor of the B hospital. Therefore, it is recommended to explain the dangers of radiation exposure to patients and provide a place for patients to wait. In addition, a plan should be sought to prevent patients from receiving radioisotopes from using unnecessary movements and general public restrooms.

A public restroom is different from a household toilet in terms of location and a large number of sharing users. In addition, public restroom is usually messy and filthy. Recently, public toilet tends to be clearly managed than before, but it still has hygienic and clear problems. In this paper, we propose a machine-to-machine (M2M)-based public restroom management system to solve these problems, in which the system with a wireless communication device sends the status information of the toilet, such as blockage or trouble detected by a sensor, to the manager of the restroom at a remote location. In particular, we have developed a prototype management system for public restroom taking into account several system requirements, and verified the basic operations and performance of the management system. With the application of the system to public facilities, it will furnish users with more pleasant environments by restroom administrators who can respond effectively to the troubled toilet.

In restroom on high-rise building, exhaust system comprising the blower and duct is installed to discharge the odor and the water is suppled. Thus the restroom with fire and flame protection system may be used as refuge area in a fire situation. The study presents the smoke-proof system which operates such that the exhaust system to discharge the odor is converted to air supply system and appropriate pressure difference between the restroom and the accommodation is maintained. Also real-scale test facilities of smoke-proof system for refuge space using a restroom are installed on 5-story smoke control test building and experiments for evaluating the operational performance of smoke-proof system are carried out.

Unlike other educational spaces in school facilities, restrooms have remained unpleasant spaces without reflecting the change in social awareness and students' lifestyle. In the process of the 'School Restroom Environment Remodeling Project in Seoul' by means of "user participatory design method", this study aimed to suggest a design of the school restroom environment responding to the different needs of actual users, who are students and school staffs. By surveying them, it was revealed that they have a variety of respective behavioral patterns and spatial needs according to their status, gender, age and working period. Implications of this study are as follows; First, it is necessary to establish a separate restroom facility standards that respond to the characteristics of elementary school students. Second, there should be an expansive approach to widely accommodate with the users' needs that were found out through 'user participation', more than just repairing pre-existing space. Third, it needs to have critical review of the maintenance and operation system itself as well as the improvement of the school restroom environment.

This thesis aims to show the design logics and the meta-design of a public restroom "Between You and Me." This work reinterprets a public restroom regarded as the typical public space by means of spatial agency's influences, on the assumption thor spatial agency controls the properties of public space. This thesis examines our representational system against the public space, and our specific experience in it with the conceptual model of meta-design. Meta-design is a design beyond the design usually we think of. Experiential meta-design, "Between You and Me" presented as the object of this thesis, is a constructive design project which converts our negative perception of the restroom to a new one, "interface." This project, composed of the surrealistic spatial arrangement, urges us to reconsider our fixed thoughts of the restroom and try a creative experience in it. Finally this thesis shows how the space's way of existence fixes our acts and thoughts, and what enables the repetitive acts and thoughts often emerged In our relations with the public space through a meta-design.c space through a meta-design.

To assess the risk level of a public restroom implemented in virtual reality, we sought to evaluate the spatial elements present in the restroom. To provide the theoretical foundation for the evaluation subjects and criteria, we introduced prior research that proposed a checklist to entance the safety of public restroom. To set up evaluation criteria, we analyzed and established based on the theories of Paul J. Brantingham and Patricia L. Brantingham, focusing on the interaction between space and criminals. Ronald V. Clarke's "Routine Activity Theory" was also introduced and incorporated into the evaluation approach. We analyzed based on the correlation between the criminal, user, and spatial elements of the public restroom in terms of the criminal's actions, the spatial relevance to crime, and user exposure during use. Using these criteria, we developed an algorithm to evaluate th spatial elements of public restroom. Based on this, we created an application, demonstrating the feasibility of developing on evaluation tool.

This study was to analyze physical condition on the dormitory high school in Jeonju City, and find out users' satisfaction on that. This was going to contribute to the directions of it's physical environmental improvement. This was performed by a questionnaire survey method. Data were collected from 200 students, who had been dwelling 4 high school dormitories in Jeonju City. Through analyzing those data about library, diningroom, laundry room, break room, computer room, restroom, shower room, hall lounge, and snack bar in a dormitory, the results are as follows. First, students thought some physical conditions to be inconvenient in an distracted study atmosphere and hard furniture of library, a bad location of diningroom, a short laundry machine, lack of tables in a break room, a short performance and supply computer, a small space and short toilet in restroom, and a short of hall lounge and snack bar. Second, the students' satisfaction of common public areas in dormitory was 3.39 score. Students were concerned with library and restroom shower room through analyzing satisfied and unsatisfied areas. Third, they needed to improve heating, cooling, and noise in common areas of dormitory, and needed to support a breakroom and snack bar. Conclusively, library, restroom shower room, break room, and snack bar were important common areas, and indoor environmental elements - heating, cooling and noise- were important in high school dormitory.

A ward is a place where the patients are living and staying for 80% of the all those days in the hospital. So the Ward's conditions are very important to them. We group a ward's conditions in two classes, one in the physical condition ; area, noise, temperature etc. and the others is the physical condition ; privacy, field. According to the analysis, the patients had beed under a mental stress and they did negative action, by the ward's environmental conditions. This study find influence of the ward's environmental conditions with violate each patients privacy using multi-bedroom's restroom. So we suggest that the ideal multi-bedroom's restroom, solve the they got the problems.
