The seismic responses of small-scale spatial frames such as school gymnasiums are usually evaluated using static analysis, although time-history analysis should be carried out to fully incorporate the dynamic responses of the structures against seismic motions. In this study, advanced static analysis procedures arc presented for school gymnasiums that will improve the performance evaluation against seismic motions. The seismic loads are approximated by equivalent static loads corresponding to the two performance levels; i.e., Levels 1 and 2 defined by the Japanese building standard. The importance of utilizing the eigenmode in the load pattern is discussed. Simple static analysis procedures are presented for evaluation of maximum vertical acceleration. It is shown that the static analysis for Level 2 input significantly underestimates the responses by dynamic analysis; however, the inelastic responses for Level 2 are shown to be successfully evaluated using the equivalent linearization that is similar to the $^{\circ}$Dmethod based on calculation of limit strength$^{\circ}{\pm}$ for building frames in Japan.

A bake-out process using auto switchgear for five days was performed to evaluate the reduction effect of the concentration of volatile organic compounds (VOCs) and formaldehyde in a newly-built elementary school gymnasium. Reduction rates of VOCs were observed as followings: 38.2, 64.2, 86.3, 80.2, and 71.5% for benzene, toluene, ethylbenzene, xylene, and styrene, respectively, which satisfies the indoor air quality standards of newly-built apartment houses in Korea. The reduction rate of total VOCs and formaldehyde were 67.0 and 24.7%, respectively. Those results proved that the bake-out process using auto switchgear was effective for reducing indoor air pollutants.

Recently, there are three major trends in building school facilities by government. First trend is to reconstruct facilities that have been built for 30 years. Second is the creation of a new town, new construction demanded from the redeveloping area. Finally, third is to build educational convenience facilities such as gymnasium, auditorium and cafeteria etc. When building or reconstructing school facilities, it is important to consider the 7th Education curriculum. The purpose of this study is to propose the guide line of the planning the dimension of Science Laboratory in in elementary school, corresponding to teaming contents and method.

본 연구는 A체육대학교 옥내운동장 5곳을 선정하여 현재의 조명환경을 파악하고 수평면 및 수직면 조도를 측정하고 분석하였다. 고천장인 실내테니스장 배드민턴장, 핸드볼장과 저천장인 유도장과 탁구장을 선정하여 측정한 결과 평균조도는 실내테니스장 483[lx] 배드민턴장 272[lx], 핸드볼장 471[lx], 유도장 284[lx], 탁구장 370[lx]로 기준조도보다 상당히 낮게 측정되었다. 수직연 조도와 균제도도 권장치보다 낮게 나왔으나 연습경기장이므로 수평면조도를 충분히 보완한다면 연습하는 데는 큰 무리가 것으로 보인다. 전반적으로 조명환경이 열악하고 설비가 노후화되어 있으므로 시설보수 시 시뮬레이션을 활용하여 종목별 경기특성에 맞는 환경을 갖추도록 연구검토가 필요할 것으로 판단되었다.

Cable dome is one of tension structure which is gradually stabilized by tensioning tables from initially unstable state to finally stable state. This stabilizing process is not able to be developed by general analysis because some cables endure compression forces during stabilizing process. Thus, this paper uses dynamic relaxation method to solve this problem. To apply this stabilizing process analysis to the actual project, this paper deals with cable dome roof of Seoul Olympic Gymnasium. Finally, this paper prove the usefulness of stabilizing process analysis by comparing the analysis results and the measurements.

This study dealt with the comparison of lateral baring capacity for vertical PHC pile between predicted and measured values driven in weathered granite soils to build world cup gymnasium in Kwangju area. Recently, the calculation of horizontal bearing capacity of piles foundation has been considered very important for earthquake or wind resistant design in Korea. During this study , Matlock & Reese, Broms and Chang's methods were selected in prediction of lateral resistant of PHC piles. As for case study, the prediction values were compared with 5 measured ones based on ASTM. The result showed that prediction values proposed by Matlock & Reese , Chang and Broms were smaller that real values. Three proposed methods by Matlock & Reese and Chang based on lateral deflection and Broms by ultimated lateral resistance turned out valid in view of engineering practice.

태권도는 국제스포츠연맹 회원국수 10위를 자랑하며 올림픽 정식 종목으로 전 세계인의 사랑과 관심을 받아온 스포츠 종목이지만 영상분석을 통한 새로운 분야에선 관심을 받지 못하고 있는 실정이다. 따라서 이 논문에서는 컴퓨터 시뮬레이션의 기법을 활용하여, 태권도의 새로운 품새 동작을 창작하는데 활용할 수 있는 시뮬레이션 알고리즘을 제시한다. 또한 이 논문에서 제시한 알고리즘은 사용자가 원하는 환경에 따라 여러 가지 조건의 변화를 반영하고 그 각각의 결과를 보다 쉽게 얻을 수 있게 되어 있어서, 향후에 새로운 태권도 품새 개발과 표준화된 동작 모델 개발에 활용될 것으로 기대된다.

We explore what factors influence the residential choice and mobility of people, and try to figure out the preferable residential district in Deagu. Household, housing characteristics, and neighborhood environments are considered as explanatory variables to predict the residential choice and the preferable residential district, and logit regression is used for the analysis. We found age, ownership, income, property, and education level as household characteristics, building age as housing characteristics, and accessibility to park and open space, public library and shopping mall as neighborhood environments are significant in determining residential choice of people whereas housing size, accessibility to elementary school, local market, cultural facility and gymnasium are not significant. These results imply people choose the residential district according to household characteristics as they did, as well as choose according to housing characteristics and neighborhood environments which are newly issued factors.

The Great Wall is an element in University which stand outs as a landmark. The Great Wall is located in front of the grand staircases of the gymnasium in the main gate area. Falling water and Lights shows a spectacle panorama in various point of view. Water falls down the top of the grand staircases and the front walls. And the red, blue and green lights brighten the falling water in the evenings. Also the relief of the palm tree and turtle symbolizes the University Identity. The wall is comprehends not only the day and the night but four seasons. The Water, Lights, and the Relief are coordinates well along with the new building in campus.

In KSC 3706, the gymnasiums are classified according to their size(small, medium, large) and there are two kinds of illumination arrangement method for them such as Side and Distributed. The characteristic of the distributed illumination arrangement method is excellent in uniformity and the characteristic of the side illumination arrangement method is excellent in glare. but illuminations were so diverse that features are not always applicable. So in this paper, in this paper, We analyzed characteristic of distributed illumination arrangement method and side illumination arrangement method using nine illumination.
