The purpose of this study is to secure an evacuation time and to ensure safety by using an Ubiquitous Sensor Network computing when a fire breaks out at a super high-rise apartment housing. A super high-rise apartment housing that is a type of building to solve the problem of separation of the urban function and the phenomenon of hollowing out downtown has been on the increase, high-rise apartment housings occupying 52.7% of whole housings in 2005. However, if a fire breaks out, there would be serious damage since it accommodates many people and facilities as existence of vertical gigantism in the city. The architectural law in force has no clause on it which is universally applicable to general building, it is difficult to be applicable to a densely super high-rise apartment housing and there would be in danger of a resident's evacuation in the fire. Therefore, as a previous study to introduce an USN-based fire-warning facility and evacuation equipment, this study shows the improvement way after analyzing factors that are barriers to evacuaee's behavior of a super high-rise apartment housing and also shows establishment of the grade of vertical evacuation rank by SimuleX, one of the best computer simulation program.

This study analyzes the effects of personal lockers, drinking fountains, and all-in-one shutters (hereinafter referred to as "corridor walking obstacles") on evacuation safety to suggest the necessity of operating a more effective educational facility safety certification system. To achieve this purpose, the five-story high school building with the obstacles installed in the corridor has been chosen, and evacuation tests through the Pathfinder Simulation Program have been carried out. When the evacuation exit is designated in the current state, where the students are placed on the 2nd, 3rd, and 4th floors and the corridor walking obstacles are applied as a variable, the required safe egress time (RSET) is 322 seconds. This can lead to dangerous results in the event of a disaster by exceeding the available safe egress time (ASET) standard of 240 seconds by 82 seconds. When students are placed on the 1st, 2nd, and 3rd floors under the same conditions, the RSET is 214.5 seconds, 25.5 seconds lower than the ASET standard, indicating that it is effective in reducing the impact of walking obstacles on evacuation time. The safety management plan for walking obstacles in the corridors is discussed, considering the special characteristics of the school corridors. The results of this study can be used as the necessary data for optimizing evacuation routes in corridors and creating a safe, educational environment.

As environmental pollution becomes serious, natural disasters are frequent and damage is increasing. Also, due to population overcrowding, social disasters are frequent, and it is difficult to predict due to the variety of area, extent, and damage. As the disasters have diversified and the scale of the damage has increased, the scale of evacuees and the period of evacuation have diversified. Should be provide facilities that will be protected from second damages to victims who have lost their homes quickly. It supports a prefabricated house, but it is difficult to supply it. In this study, the ultimate goal is to plan an outdoor temporary housing facility that can supply quickly when the capacity of the evacuation facility is insufficient or the evacuation facility is insufficient.

The purpose of this paper is to investigate the difference in facilities of natural recreation forests developed by public and private body to answer the research that what is the difference in development of natural recreation forest between public and private developer\ulcorner After reviewing the literatures, developer's decision-making and motivation of investment, and the planning process of natural recreation forest, we had constructed th conceptual framework and have found the hypothesis of this research. Using data on development status of natural recreation forests and questionnaire surveying of 625 visitors from 9 among 72 natural recreation forests in Korea, We analyzed the data through the comparison of quantity of facilities per 1000 visitors and logistic regression method for quality of facilities. We have found that 1) the six facilities have been turned out to be statistically significant in determining the difference of public and private recreation forests. i.e., infrastructure including roads, maintenance and information and lodging and evacuation, indoor education, outdoor education, and shopping, 2) public recreation forests are well equipped such basic facility as roads, maintenance and information, lodging and evacuation while private recreation forests are well equipped such facility as indoor education, outdoor education, and shopping, and 3) the importance of such facility as roads, maintenance and information, lodging and evacuation, outdoor education, and shopping have been turned out to have 1.99, 2.26, 1.99, 3.01 and 2.24 times more important than that of indoor education, respectively. We can conclude that public recreation forest seems to be equipped with the facilities for sound recreational opportunities for general public, and private recreation forest turned out to have more facilities for pursuit of profits, installed basic facilities for user convenience and service, and special facilities for attracting user and raising revenue. Using the results of this research, we can make a guideline for a market positioning, and standards and provisions of natural recreation forests. We suggest that the relationship between user-satisfaction and recreation facility is needed to be examined in the future research.

The purpose of this study is to suggest that performers in the performing arts actively utilize the loading dock and stage door when evacuating from the stage space of a performance hall in a crisis situation. Therefore, first, we analyzed the system related to the performance hall's safety. The stage evacuation type was classified into A, B, C, and D forms by applying the building law audience evacuation standards. Second, statistical data were organized based on measurement data, and the characteristics of each form were summarized. Third, the network reliability measurement method was borrowed to evaluate the evacuation safety of the evacuation route in the stage space. We confirmed quantitatively that the direction of the loading dock direction and stage door direction on the stage is advantageous for evacuation. In this study, it was possible to distinguish the advantage of evacuation according to the type of evacuation, (A(0.1274)>B(0.1228).>.C(0.0487)) with A being the most advantageous. These results can be expected to improve the evacuation safety of the stage, and furthermore, they are expected to be used as basic data for stage evacuation.

The purpose of this study was to obtain baseline data on dietary management of women's constipation. We estimated the prevalence of self reported constipation, bowel habits and foods & nutrients intake. The subjects were 169 female college students (normal = 92, constipation group = 77) aged 19 to 23 years. We conducted anthropometric measurements, an evacuation habits survey, and a dietary intake assessment for three days by a 24 hour recall method. The prevalence of self reported constipation was 46% (n = 77). Results showed that bowel habits (the difficulty of evacuation, the duration of evacuation and the feeling after evacuation) were significantly different between the two groups. Over 65% of constipation group used laxatives for constipation relief. Frequency of stress and deep sleeping were related with constipation. In daily food consumption and nutrients intake, there was not a significant difference between the groups. However in relation to bowel habits which factors influence constipation, the study showed that the intake of water, potatoes, kimchi, and fruits correlated with evacuation facility. Further, there were no findings in the difference of foods consumption and nutrients intake between the two groups. But some life style changes and food intakes (potato and kimchi) may be useful to improve constipation symptoms in young women.
