This study investigated the characteristics of architectural planning in the youth training centers, which were introduced to the magazines from 2000 to 2010. The result are as followings. Firstly, the youth training centers were located mainly in general residential area, that the youth could be easily accessible. And, it were located mainly in green natural area, which is adjacent to the mountain or park. The site area of the youth training center was analyzed to approximately $10,000m^2$ below. Secondly, the placement and the form of the youth training center is divided two types, which are a single and two buildings type. A single building case is found the type of 'ㄴ' and 'ㄷ' shape, and two buildings case is found the type of 'ㄴ + ㅡ', 'opened ㅁ', 'ㅡ + ㅡ' shape. It is found mostly the type of 'ㄷ' shape. Thirdly, the youth training center is planned mostly with fifth stories above ground and three underground levels. And, sometimes it is planned a mixed-use buildings with a sports center, community center and senior welfare center. Lastly, the space of youth training center is zoned horizontally for each mass of building, which is planned the educational, cultural and sports facilities. And, it is zoned vertically some of the sports facilities and administrative support facilities in the underground, and a educational and cultural facilities on the ground.

This study aims to analyze architectural characteristics of railway station facilities which were built with development of railroads from Japanese Colonial Period to 1950's. To achieve this goals, 7 railway stations in Gyeongju area that are worth preserving were set up as research targets. For this study, I analyzed literature of the railway station and drawings which the KORAL Daegu Branch is keeping. Railway stations without a construction drawing investigated a direct visit. After analyzing the railway station facilities, the architectural properties such as plan, elevation and section have been identified. The results are as follows. First, Each modern railway station is usually consisted of waiting room and office, and ancillary spaces have been added. Over the years, however, the space was expanded horizontally. In that case, the structure and finish materials have been changed, like now. Second, Most of the roof shape is 'Matbae'(gable roof), especially Gyeongju station and Bulguksa Station are 'Woojingak roof. The roof structure is truss structure, especially as Pratt and Scissors type, but Gyeongju Station's structure is a reinforced concrete. Third, main doorway of waiting room is located in the center of the front gable. However, small stations like 'Ahwa' and 'Ipsil' station to ensure the passengers' waiting area are placed next to the office area.

Photovoltaic(PV) permit the on-site production of electricity without concern for fuel supply or environmental adverse effects. The electrical power is produced without noise and little depletion of resources. So BIPV(Building-Integrated Photovoltaic) system have been increased around the world. Hereby the relative installation costs of the system will be relatively low compared to traditional installations of PV in high-rise buildings. This paper examined possibility of BIPV system of cold facade type and analyzed of performance of BIPV system of cold facade type. The system is influenced by conditions such as irradiation, module temperature, shade and architectural component etc. If this BIPV system of 1.1kW is possible the natural ventilation in the summer case, the temperature of PV module decrease and then the efficiency of PV system increase generally. By the results, the annual averaged PR of BIPV system of cold facade type is about 73.1%.

In terms of plane structure, tower-type apartments have several disadvantages compared to flat-type apartments in the aspect of ventilation rate. Such disadvantages may not produce good indoor cooling effects with natural ventilation inside the heated apartments in hot summer days, so they may cause high energy consumption by an increase in cooling load. The purpose of this study is to investigate ways for improving the indoor thermal environment of tower-type apartments in summer by conducting quantitative evaluations of the airflow distribution in households.

According to the labor related data from Korea Occupational Safety & Health Agency, accident victims of construction industry are increasing 6% annually since 2006. The major reason why the rate of accidents increases in Korea is that lots of labor working with another trades works simultaneously in various type of works. This study analyzes the current accident status in view of the type of building, type of works, and project size for the latest 3 years (2007~2009). As a result, 'single family & semi-detached houses' has the largest number of accidents among buildings. In addition, 'finishing work' shows the highest number in terms of work type. For the size, accidents occurred much for 'less than 300 million'. The results of this study can be used to focus on managing the highly hazardous area where the construction accidents mostly occur; therefore, it is anticipated to contribute to improve efficiency of safety management.

This study aimed to distinguish categories of archival information and identify properties by their detail types, so that the various forms of architectural heritage information generated can be managed based on their attributes and characteristics. First, the specific uses of terms in the legal system were reviewed and their associated concepts specifically defined. "Architectural heritage" was defined as architecture belonging to the category of tangible cultural heritage as designated by law, and "architectural heritage archival information" was defined as all kinds of material expressed by electronic processing of the actual status for preservation and management. Next, the production status of architectural heritage archival information was reviewed in relation to the legal system. This confirmed that relevant legal systems were organized hierarchically and that various types of archival information were generated in a single project. Furthermore, it was confirmed that even archival information produced in the same form contained differing contents depending on the specific purpose and method, and that there was no classification by which to cover all archival information. Finally, it was also confirmed that detailed drawing types could be categorized according to the purpose of production and the target of the records. Based on the findings of this review, the type and properties of archival information were presented as the primary classification criteria, and the architectural heritage archival information was divided into 6 general types and 27 detailed types. Specifically, the linguistic form, dimension, temporal property, and graphic form of archival information were applied as criteria for the classification of general types, and the target, production purpose, production method of archival information, and content characteristics of archival information properties of archival information by type were comprehensively reviewed.

Currently, social demands for long span building structures are increasing due to architectural planning purposes and economic efficiency. As a result, lighter board-type voiding materials were suggested. With the use of board-type voiding materials, a slab is able to become light weight and convenient. This process efficiently eliminates concrete where it is not required; considerably diminishing dead weight while maintaining the flexural strength of the slab. The reduction in concrete also allows for overall cost reductions and design flexibility. Also it can be ease with fixing the voided material that is composed of one body form. Although board-type voiding materials are ideal, the top and bottom concrete plates lack integrity. Because of this, test results show horizontal cracking towards the tops and bottoms of the concrete columns, or webs, connecting the slabs. The key to correcting this problem is to increase the shear strength. In order to increase the shear strength of the structure, horizontal shear area must increase. R70(100)-D-F has the largest horizontal shear area as it also shows stronger strength. As a result, shear strength ($V_{nh}$) is dependent on the horizontal shear area (N). $V_{nh}={\alpha}{\times}0.16{\sqrt{f_{ck}}}{\frac{{\pi}D^2}{4}}{\times}N({\alpha}=1.8125)$. The web columns have a shear span to depth ratio (a/d) that is less than 2; which classifies it as a deep beam. In this case, however, the shear strength of the deep beams may be as much as 2 to 3 times greater than that predicated conventional equations developed for members of normal proportions. As a result, ${\alpha}$ is suggested as an extra coefficient in the equation for shear strength ($V_{nh}$).

This study investigated defect status by work type, based on the report data of defect inspection results, acquired by consumers' request to safety inspection agencies, before the expiration of legal defect repair warranty period. In fact, the data was not acquired by centering on suppliers, namely, construction companies in relation with the defects becoming causes to increase construction cost of apartments. This study aims to provide objective and basic data for quality improvement at construction stage and for solution to defect disputes. The study results are presented below: (1) The number of defect cases occurring from architectural work among total work types were 1,986, defect occurrence rate was 62.5%, and defect repair cost was KRW $25,851/m^2$, which stood at 78.2% of the total work types. This means the defect occurrence rate and defect repair cost in architectural work are bigger than those of other work types. (2) Major defects in architectural work were revealed in the following order: cracks from frame work, inferior interior finishing work, inferior finishing work of plaster/masonry works, water leak/damage from waterproof work and withering/omission from landscape work. The total repair cost of the major selected defects was KRW $12,220/m^2$, and was analyzed to take up 37% of the total defect repair cost.
