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.

The For the last half a century, Korea has been experiencing rapid economic growth and industrialized development, however they cause serious problems that environmental pollution and energy shortage have appeared, and the biggest problem that Koreans are now confronted are required solutions throughout the world. At that time, Korea's energy consumption ranks 10th in the whole world. Among them, energy for buildings, about 25% of the total amount of energy consumed in Korea, is very serious. Especially, the energy consumption of school buildings, which have a heating & cooling system according to improvements of the educational environment, is rapidly increasing. These features are explicit in the University, Because it has lots of colleges and facilities for lecture, experiment, and research. In this paper, the energy consumption of Kyungpook National University which is at Daegu, Korea was investigated. This study attempts to appoint the place which is one of University and to investigate the characteristics of energy consumption like electricity, gas, oil. Using the investigation results, we can obtain the overall trend of energy consumption of the university and provide important data basis to guide rebuild and extend construction of school in the future.

Recently, there have been frequent occurrence of the damage to lives and properties due to the torrential rain caused by climate change. In consideration of the current situations in which the underlying data related to flooding are lacking, this study conducted to build up the basic data on the flooded areas and suggested methods to secure the evacuation routes that can be accessible to evacuation facilities in the residential buildings. Methods of the study are as follows. First, We calculated the flood risk grades of residential buildings based on elevations, considering the flooding characteristics of the flooded areas in Buk-gu, Daegu. Second, We constructed baseline data on the evacuation routes through site investigation and reviewed of drawing using Arc GIS to identify vulnerability to access to the evacuation facilities, targeting the residential buildings. Third, We carried out the proximity analysis through a near analysis of analysis functions in ARC GIS. Forth, We deduced 115 residential buildings in which access to evacuation facilities is considered to be difficult based on the analysis results. Finally, We proposed extension of a blind alley as a means for achieving connectivity to evacuation facilities. And to evaluate the alternatives presented, we reconstructed route data. As a result, about 53% improvement was identified through the proximity analysis.

This study has examined layout of communal outdoor space and welfare facilities in the nation's very first senior apartment complex in Segok-dong, Gangnam-gu that has been developed by Seoul City. In order for this space to play a role as a center of communication: 1) A center space of community should be created at the point of intersection of main moving lines of pedestrians. 2) Hierarchical area should be set up between main moving lines of walking and communal outdoor space. 3) It should be designed in a way to reflect demands of seniors and be accommodated their activities and behaviors. 4) It should be functionally connected to local infrastructure facilities so that it can promote social exchanges among seniors. Points to be considered in welfare facilities: 1) They should be placed at the center of the complex to provide convenience to all seniors. 2) Area of senior citizen center should be subject to flexible legal regulation in light of the unique characteristics of the Complex. 3) in case that welfare facilities are installed in the same space, intermediate space is required to alleviate collision between private space and public space. 4) Senior assistance facilities should put more emphasis on running programs that make good use of the space than on securing the space itself.

With the improvement in economic power and diversification of living patterns, the demands of household energy-consumption devices have changed. The household energy consumption accounts for 20 percent of the entire energy consumption in Korea. Among household energy consumption, electric-power consumption is expected to increase as the number of household energy-consumption devices has been on the rise. The purpose of this work is to investigate the possibility of household energy saving through the "the way of reducing the use hours of devices and their use" as the other energy saving way than "choice of highly efficient devices". To achieve the purpose, this researcher conducted a questionnaire survey with 2,250 households in the country to look into the state of the possession and use of household energy-consumption devices. And we investigate into the energy-saving behavior. The results are as follows. First, A household possessed 16.21 household energy-consumption devices. when we are grouping by energy-saving behavior, there is no difference the numbers of energy-consumption devices. Two, group 1 can save energy-cost about 11,000won in the winter and 15,000won in the summer by energy-saving behavior.
