Recently, the terror frequently has taken place for unspecified individuals as modern society is complicated. Especially, in case of a subway carriage fire as Daegu subway fire, because smoke spread path usually coincide with passenger"s evacuation path, it will reduce visibility and can cause fatalities by asphyxiation. This study performs not only fire simulation with CFAST V6 but also evacuation simulation with EXODUS V4 for the purpose of taking measures for passengers"s life safety in subway fire. As a result of evacuation simulation without fire, evacuation times are 36 s for EXODUS V4 and simple hand calculation, and when fire is occurred fire, 101 persons evacuated in 32 s. Therefore, a countermeasure of evacuation in subway carriage fire is required to repression of fire and emergency exit.

Many researches have been performed to analyze the smoke movement in tunnel fires by using field model. Recently, FDS(Fire Dynamics Simulator) v.4, which is one of the field model and developed from NIST(National Institute of Standards and Technology), is widely used. In tunnel fires, FDS can show detail results in local point, but it has difficulties in boundary condition and taking long computing time as the number of grid increases. So, there is a need to use alternative method for tunnel fire simulation. A zone model is different kind of CFD method and solves ordinary differential equation based on conservation and auxiliary equations. It shows good macroscopic view in less computing time compared to field model. In this study, therefore, to confirm the applicability of CFAST in tunnel fire analysis, numerical simulations using CFAST are conducted to analyze smoke movement in longitudinal ventilation reduced-scale tunnel fires. Then the results are compared with experimental results. The differences of temperature and critical velocity between numerical results and experimental data are over 30℃ and 0.9m/s, respectively. These values are out of error range. It shows that CFAST 6.0 is hard to be used for tunnel fire simulation.

This research has been concentrated on Teakwondo major student process of socialization according to their learning styles. The process of socialization includes general social role, integrative role, controlling roles and emotional roles. This research has also been aimed at providing basic data for the learners` participation in positive social activites. The following are the conclusions: First, participatory learning affects their integrative and controlling attitudes. Second, independent learning also affects their socially integrative and controlling attitudes. Third, cooperative learning affects their social attitudes and socio-emotional attitudes. Fourth, competitive learing affects their social attitudes, socially controlling attitudes and socio-emotional attitudes. The following effects are expected based on the above conclusions: First, Teakwondo learners can foster socially integrative leadership and decision-making abilities. Second, Teakwondo learners can foster socio-emotional abilities through group-life and small-scale social activities. Third, Teakwondo learners can foster self-controlling abilities, respecting manners and emphasizing spiritual abilities. That is, they can control themselves, overcoming psychologist Freudian aggressive trends.

The purpose of this study is to survey systimatically on the ever-increasing social sports facilities as well as the people's interest and concerns in sports activities and find out the developmental direction plus desirable operational patterns. The subjects of this study are consumers using commercial sports-centers and the non-consumers(the group not using sports facilities at present) are 20 years old or above. A total of 660 persons were sampled at random including 357 sports-center- using consumers and 303 non-consumers. The results of the study are as follows. 1. The factors for participating in commercial sports activities can be different according to life-styles, influenced by consumers' genders, jobs, ages, educational backgrounds and incomes. 2. In the logistic analysis on using sports-centers, of the life-styles affecting using sports-centers, factor 2(health-management type) and factor 4(human-relationship type) influence using sports- centers positively and factor 1(methodical life type), factor 3(fashion-pursuing type) and factor 5(se1f-control type) influence using sports-centers negatively. Health-management and human-relationship types show a lot of social approaches through sports as well as efforts and concerns for health. The reasons for using certain sports-center facilities are closely related to traffic problems for the local consumers in the neighborhood , excellence of sports facilities and using fees, so these factors are the pre-requisites needed to devise a consumer-marketing stategy and also important for selecting a sports-center site. As using sports-center facilities is dependent on life-styles, the marketing stategy according to life-styles is needed. Also the market is needed to be classified in detail according to the methodical life-pursuing group, fashion -pursuing group and selp-control group which show a negative relationship to using sports facilities and it is necessary to get information on diverse desires as well as potential market size and the sports programs should become a useful yardstick to review how much these programs satisfy consumers'desires.

All estimation about agineungjeok image and symbolic Imijia which is of commerce sports center image Hawibyeon is anateuma level, and intention about a ashes consumption and all appeared by anateuma level. And in service quality assessment connected with program withering member bicarbonate of soda and contrast for member affirmative .Therefore, service quality, service value, estimation level about image and ashes consumption intention that commerce sports center consumer is recognizing, word of mouth communication intention is contradictory more or less and also, bicarbonate of soda member in service quality assessment which service quality estimation connected with main equipment and employee is affirmative, and is involved with subsidiary facilities than another thing education level group bicarbonate of soda and withering member contrast for member affirmative . And estimation about symbolic image is affirmative, ashes consumption intention level is high. Exercise participation degree and service quality Hawibyeonin that other commerce sports center consumption experience Hawibyeon is do not influence in ashes consumption intention and word of mouth communication factor.
