A high-temperature effect of urban due to industrialization and urbanization contributes a significant effect on urban environment, migration decline of sensible and latent heat in accordance with a heat island effect and ground surface change. The results of the study are as following. First. The characteristics of urban thermal environment according to land usage on AWS region can be determined by looking at the behavior of temperature changes shown on a clear day during summer season. Second. For the relationship between land usage changes and urban thermal environment on AWS region, the study have determined that increase in urban heat occurs when the land-cover of city center exceed 50%. Third. Result of simulation conducted to determine the characteristics of heat environment in accordance with land usage had shown relatively even temperature throughout the target area around 10:00 fourth. The researcher has conducted simulation for determining the characteristics of wind speed in accordance with land usage. Result of analyzing wind direction and speed at 10:00 AM and 14:00 PM, the researcher had found that the mild wind blow had not affected the temperature changes severely.

Underground spaces are actively being developed. Especially, the trend of this development is horizontally to connect other buildings by underground floors, that is, to make underground passages among buildings, it seems to be a great network space. Many inexperienced pedestrian are not aware of these passages and are anticipated to be exposed to a great of danger when there is a fire. It happened that the fire at Joong-Ang Ro station of Daegu. It might be ended as fire happening. However, it proceeded to the disaster giving a number of damage because of the incomplete system of disaster prevention. Now we will need the new fire fighting activity's system at the conflagration of underground space. This study is to research the fire fighting activity and to analyze the fire fighting system at the Daegu subway fire. And This data will use in base of fire fighting activity at the conflagration of underground space.

In Korea, the Seoul subway line 1 was opened In 1974 and the subway service is being operated In Seoul, Pusan, Daegu, and Inchon The subway station is related to a underground shopping mall that was developed as complex spaces According to the time of people's stay at the underground space, the necessity about the safety countermeasure of the underground space has been enlarged Consequently, the efforts to minimize the damage of human life and property from similar underground fire occurrence or disaster is important In this research, we analyzed the survivors behavior's pattern and the way of evacuation from the Daegu subway fire disaster on Feb 18 2003, In which 192 people were killed and 148 injured We investigated about survivors of the Daegu subway fire and analyzed the factors of human behavior and evacuation in the underground space fire As a result of research, greater part of the interruption to escape is the loss of the direction to escape We need to install with suitable guidance devices according to the fact we have The device should be equipped with not only visual indication but also with tangible and audible

The housing construction has been quickly changed by construction of apartments since 1960. An obsoleted apartment house has been increased by political measures with quantitative enlargement of housing supply. The redevelopment and reconstruction of housing have been activated as an alternative plan. The redevelopment and reconstruction for existing buildings increases in construction wastes, which is influencing on both management and disposal of construction wastes, besides the quantitative augmentation of construction wastes have an effect on both society and environment. Therefore the management and disposal system of construction wastes is demanded from a side of the both society and environment. The purpose of this study offers basic data to compare and analyze both the kinds of construction wastes and the ways of disposal of these wastes generated when founding and dismantling residential buildings.

Nowadays, a source of all water, which has been spent by a lot of people, is the rainwater. The rainwater is directly relating human being' life. According to how to use rainwater, human being' life is abundant or poor. Due to the lack of underground filtration quantity, the water circulation of the city is discontinued and the underground ecosystem is destroyed. Therefore, the natural space has disappeared and it is presently raising its head with social problem. The new regulations of water service were released by Ministry of Environment in Korea, which was recognized of the necessity of rainwater' use, so that the foundation of equipment to use rainwater facilities was imperative. Although the facility to use rainwater is increased in the our country , the recognition against a rainwater' use is lower.According to the new regulations of water service, the facility to use rainwater is available to In-Cheon, Su-Won, Jeon-Ju, Dae-Jeon, Je-Ju Worldcup stadium at the present time. In this study, it is investigated that the actual conditions of the facility to use rainwater and to analyze aneffect from Worldcup stadium. This study that introduces a rainwater use facility in the Daegu Worldcup stadium. will analyze an economical evaluation and the effect

Normally, subway station is related to a underground shopping mall that is developed as complex spaces. As it took a long time that people were staying in the underground space, the necessity of safety countermeasure of this underground space has been enlarged. Consequently, the efforts to minimize the damage of human life and property from similar underground fire occurrence or disaster becomes important. In this research, it was analyzed the survivor's and savior's behavior pattern and the way of evacuation from the Daegu subway fire disaster on Feb. 18. 2003, in which 192 people were killed and 148 injured. It was investigated survivors of the Daegu subway fire and analyzed the factors of human behavior and evacuation in the underground space fire. And it was investigated savior's route when savior saved survivors.As a result of research, greater part of the interruption to escape and to save is the loss of the direction to escape. It needs to install with suitable guidance devices according to the accident. And the devices that helps the saviors are light and sound. The device should be equipped with not only visual indication but also with tangible and audible. The emergency in underground space is complicated and peculiar. Because underground space is the place where people and smoke evacuated at the same time. Therefore saviors search various savior routes. And the fire fighers and saviors need communication utility each other.
