The purpose of this study was to find a suitable standard height of the lavatory in public spaces through the review of relevant regulations, questionnaire survey, lab works, and experiment to measure lavatory heights. The results of the study were as follows: First, the heights of the current public lavatory were ranged from 68cm to 89cm, and the heights to the faucet were from 71cm to 91cm. The recent lavatory was more likely to be higher in heights. Secondly, the suitable height for public lavatory was ranged from 55% to 65% of the heights of the participants put on shoes. Thirdly, 90cm lavatory in height was considered to be more suitable to use for the majority than was 83cm lavatory. Fourth, the author suggest that the suitable y(lavatory height)=77.818 + 0.117x(put on shoes heights). This study suggested that adopting 95% range, the most suitable height of public lavatory is more than 90cm high for the people whose heights are more than 150cm.

Nowadays a lavatory an essential place in the house and located the inside of the house. But, there were few research about the lavatory so that in this study, the transition and the current condition of the lavatory in the Korean houses were examined by the related materials. The results of this study showed that: 1) Location of the lavatory in the agricultural society was decided by the relationship with other spaces. 2) The introduction of other cultures and the change of the people's perception on the lavatory influenced the change of location of the lavatory from the remote place to inside of the house. 3) The construction of apartments and development of the drain system caused the lavatory to be located next to the bedroom in the house.

If an urgent situation, such as a stroke, faint, heart attack, happens in a lavatory, it is hard to recognize and perform an immediate emergency treatment unless the patient inside of the lavatory calls for help. If a system that can detect an emergency in a lavatory and report to the relevant personnel is developed, it would be an excellent installation case demonstrating how a train is nicely designed to take care passenger's safety. In this paper, we showed a design of lavatory emergency detection system (LEDS) that detects an urgent situation in a lavatory by using sensors and timers and reports to proper personnel. This system can be installed not only on a train but also in a building where visual monitoring is not possible.

We discussed the change of housing environmental problems from the early 1900s to the present in Study(I). This study(II) which secendly research of study(I) analyzed the fixing precess of a lavatory centering around a excretion which was a serious housing environmental problem in 1920 to 1940. The documentary research method was used for this study. Articles of content analysis(N=185) were published in 1920 to 1990 which were The Deng-A daily news article about a excretion and a lavatory. The main content of this study was examined the change, such as the number of whole article, the column number of article by time series. and the content of article by subject. 1. The number of whole article by time series was collected mainly in1920s-1930s. In 1940s-1960s, one-two column of article was appeared generally and three-four, five column of article was appeared in 1970-1980. 2. Contents of article was divided into two classes, excretion and lavatory. Contents of excretion was 1) a use of fertilizer 2) the method of transportation 3) a cost of gathering 4) a place of disposal 5) the problem of cleaning. Contents of lavatory was 1) a public lavatory 2) a flush toilet 3) a sanitary conditions 3. 1) A use of fertilizer was concentrated in 1920s-1930s, and problems of it was solved more or less by change of management method. Transportation of excretion developed such as \ulcornerGue\ulcorner->a coach of tank style->underground transportation->a dung car of absorption style. Disposal place of excretion was a cause of dissatisfaction in 1920s and it is serious problem Today. A duty of excretion gathering was transfered to a private worker in 1978. The accunulation problem of excretion was continued until 1940s-1950s. The management law of waste matters was proclaimed in 1986. 2) A public lavatory was planned in 1924 for the first time, and it is insufficient in these days, A settlement of public lavatory in building which has upward of 20pyung became obligation in 1973. The problem of water contamination which by poor septic tank was happened in 1970s-1980s.

Objective: This study was performed to assess bacterial distribution concerned in sanitation management of public lavatory in Seoul. Methods: In this research, bacteriological investigation on public lavatory was accomplished for bidet water, bidet nozzle, washbowl and lavatory stool in the 50 public facilities such as public institutions, subway stations, cinema, department stores, large-scale buildings and hospitals amount to 374 specimens. Results: The geometric mean of colony forming unit(CFU) in total aerobic colony count were analyzed as follows; $5.2{\times}10^2/100cm^2$ on lavatory stool, $7.2{\times}10^3/ea$ on bidet nozzle, $7.8{\times}10^3/ea$ on center ring of washbowl, $1.4{\times}10/mL$ in bidet water (ml) and 7.0/ea on doorknob. Opportunistically pathogenic germs such as Staphylococcus aureus, Escherichia coli, Enterobacter cloacae, Pseudomonas aeruginosa were isolated in 3.7%, 5.9%, 3.2% and 1.9% of total specimens, respectively. Conclusion: The result of this study shows that there were some facilities where the pathogenic germs were detected to may cause urological infection. And the CFU of general bacteria as the representative indicator of disinfection and lavatory cleaning were high enough to imply the improvement of sanitation management of public lavatories should be contrived.

The purpose of this study was to fine the changes in lavatory/bathroom and daily lives to clarify the modernization process of the housing through everyday affairs and adjustment behaviors after the period of opening the port with microscopic perspectives. For the purpose, reviews were focused on hygiene and cleanliness in lavatory/bathroom and the changes in such areas. Secondly, how the process of conflict and settlement due to such changes had been approached since modernization was studied. Research method used were literature review and field study. The results of the study were as the follows: From the perspective of 'hygiene' and 'cleanliness', which were the main characteristics of modernization, the lavatory/bathroom culture in traditional Korean housing might be considered very unsanitary and despicable. The actual problems encountered by the inhabitants, however, might be less significant than those discovered by the pioneers at that time. Despite such reality, housing adjustments through renovations of the bathrooms and lavatories by some classes implied the need for housing, which had been inhibited in themselves. Also it was found that the family conflicts due to cultural and life style differences existed in each time period.

In this paper, studied was the application of IT and sensor technology to trains in order to provide safety and convenience for passengers. One of applications is Lavatory Emergency Detection System in a train. Since a lavatory in a train is securely separated space, it is hard to notice an emergency inside of it unless a user sends a request for help. A system that can detect an emergency by using sensors was presented. System requirements were analyzed to design and implement a system. Prototype of the system was made. Then, tests in a laboratory were carried out based on a set of test plan to verify the system functions. Performance was turned out to be very successful. The system developed may have a chance to be installed according to the requirements of specifications of the train to be ordered.

This research is studied changes of outdoor lavatories in use of detached houses in rural areas. Out of 40 houses studied in a 1995 survey, 23 houses were performed again in 2015. Number of lavatories installed in indoor and outdoor both in 1995 are more than in 2015. However, number of indoor lavatories in 2015 are more because outdoor lavatories were demolished. Among 23 houses, 15 outdoor lavatories have been installed in 13 houses. Out of these 15 lavatories, eight have been used continuously from 1995 through 2015. Currently four are used for other purposes, and five have demolished. Outdoor lavatories tend to be built in the rear of the housing site. Those located in rear tend to be demolished rather than in front side because of decreasing in use. In rural areas, outdoor lavatories not only serve as spaces to fulfill basic human needs, but are used to store agricultural tools. Changes of family composition and member also exert an influence. When family members were decreased, outdoor lavatories tended to be demolished. However, although family members were decreased, the reason that outdoor lavatories have been used continually is for exterior work or farming and temporarily increasing family members in holiday and family events. The more family members used, the more outdoor lavatories are managed well. The more houses where the aged reside in, the more outdoor lavatories are not improved.

As our country holds 2002 Korea-Japan FIFA World Cup, more foreigners are visiting Korea, making the tourist industry more profitable. Under these circumstances, we should pay attention to the restroom as a public facility, and inspire the awareness in the Korean people to improve the public restrooms. However, according to KNTO(Korea National Tourist Organization), it has turned out that foreign tourists are still dissatisfied with dirty restrooms and poor signposting when they visit Korea, Though the number of restrooms has been increased, they are not properly managed being a public nuisance due to negligence of administration and straggling facilities. To make it worse, poor design of restrooms and insufficient consideration of handicapped person bring disgrace on Koreas tourist administration. While studies on restrooms began from the 1980s, it has placed too much emphasis on the space arrangement and facility plan, so we need to pay attention to the traditional design and environment aspect of restrooms. This study is 1 haute looked into the problems and actual conditions of restrooms, and based on these data, applied Korean Buddhist architecture style to restrooms to create a comfortable circumstance in restrooms.

This study aims to provide basic data for designing aged care residential facilities in Korea, based on the investigation and analysis of the aged care residential services and their communal living areas in Australia focusing on their types, scales, arrangement and the specific design of each compartment. -. A residential building with 10 beds is composed of private zones and communal ones, and their space arrangement depends on how to arrange bedrooms where residents mainly stay. -. A lounge, 26.7 m$^2$ of its average scale, is a main space for daily lives and an important place for making friends with neighboring residents. -. A dining hall is an important area for activity as well as a space for dining. The average scales of dining room, kitchen, and whole space are 42.7 m$^2$, 28 m$^2$, and 70.8 m$^2$ respectively, and those for person are 2.7 m$^2$: 1.7 m$^2$:4.4 m$^2$, although the scales depend on facilities. -. An activity room is used for promoting the social relationship between residents and visitors. Three of the investigated facilities have big rooms of 42 m$^2$, 39 m$^2$ and 51 m$^2$. -. If there is no lavatory in a bedroom, 2-6 bathrooms for residents are arranged near bedrooms and they are relatively big including shower baths. If there is a lavatory in a bedroom, 1 toilet for visitors is arranged in a communal living area and its scale is small.
