The purpose of in this study is to provide practical strategy for the use of the Roof Green in pusan, this researcher reviewed the concept of Roof Green and related materials and examined Potential resources for the greening in an effort of obtaining space for Park and Greenlands within the city. In relation, the researcher measured Roof sizes of buildings, especially for schools and residence, in Busan. Then the researcher tried to determine how Roof Green implemented with the measurement would Economic effects in the resources of Park and Greenlands of the city. These processes were made to raise attention about Roof Green in cities and practical strategy for the use of the Roof Green.

Recently, as industrialization is rapidly growing and the standard of life is rising, the quantities of waste glasses have been hastily increased and most of them are not recycled but abandoned. It cause some problems such as the waste of natural resources and the environmental pollution. Therefore, this study conducted as a basic experimental research to analyze the possibilities of recycling of waste glasses (crushed waste glasses outbreaking from this country) as admixture for concrete. In this study, we have identified applicability of waste glass powder to materials of pozzolan through performance analysis. If waste glass powder is used as an admixture, workability of concrete increased as content of waste glass increased and its powder was fine. The strength properties of concrete using smaller than 0.075mm waste glass powder as the admixture shows satisfactory long term strength when 20% waste glass powder is included.

The purpose of this study is to infonn that Fengshui is a view of environment which reflects Korean people's philosophy of life and consciousness of scenery beauty. For the purpose, this researcher approached the view in two ways to draw out several indicators helpful for the improvement of disordered urban environments and applicable to environmental plans. In making the approach, the researcher defined space for settlement(village) as an environment in which traditional values of Frngshui could be discovered, Among the values, some as deemed consistent with the spatial structure of modem cities were analyzed to interpret the view of environment implied in Fengshui.
고황산염 시멘트를 이용한 고강도 콘크리트의 압축강도 특성에 관한 실험적 연구

프리텐션 방식 원심력 고강도콘크리트 말뚝이 KS F4306 규격에 제정되어 콘크리트의 압축강도가 800kg/$ extrm{cm}^2$ 이상의 제조가 불가한 실정이 것으로 평가 된다. 따라서 본 연구에서는 고강도콘크리트 말뚝 제조에 적용하기 위한 고황산염 시멘트의 실험적 연구로써 석고계 첨가량 및 단위 시멘트량 변화가 증가양생 콘크리트의 제 강도 특성에 미치는 영향을 규명하는데 목적이 있다. 연구결과로부터 석고첨가량이 증대하면 콘크리트강도가 향상되지만, 7.5% 이상 첨가시에는 오히려 강도 저하현상이 나타나는 것으로 분석되었으며, 특히 단위 시멘트량 변화에 따른 압축강도 영향은 그다지 크지 않은 것으로 나타났다. 한편 최고 압축강도 발현은 석고첨가량 5~7.5% 첨가와 단위시멘트량 500~540kg/㎥ 조건에서 800kg/$\textrm{cm}^2$ 이상의 고강도 콘크리트 제조가 가능함을 확인하였다.

The safety shoes have been used to protect the foot in the workplace. Safety shoes have been designed to protect the foot from external environment. However, it has not considered the internal impact of the foot. Therefore, this study analyzed the pattern of the foot pressure between the normal safety shoes and suspension functional safety shoes for reduction of the foot pressure. The subjects were selected 5 people who have career over 5 years in the workplace. The experiment was performed to measure their foot pressure with the suspension functional safety shoes and 2 types of the normal safety shoes. Moreover, this study analyzed the MF(Maximum Force) and PP(Peak Pressure) in the foot (forefoot part, midfoot part and rearfoot part).

Objective: To investigate the changes of shoulder proprioception in normal subjects, according to the direction of the evoked fatigue on the shoulder muscle group. Method: 20 healthy volunteers (14 males and 6 females, age 20∼35 years) with entirely normal shoulders participated in this study. Before fatigue exercises, the proprioception tests were performed during active reposition (ARP) and passive reposition (PRP) of dominant shoulder, using isokinetic dynamometer, System 3 Pro (Biodex medical system, New York, USA). Three trials each of active and passive repositioning (2°/sec) were recorded. We also estimated the results of the peak torque shoulder movements. The subjects performed maximal efforts with five repetitions on the direction of flexion, abduction, internal rotation and external rotation. The mean values of maximal concentric voluntary contraction (MVC: peak torque of each muscle group contraction) were recorded. We repeated fatigue exercises until the peak torque dropped to 30% three times consistently, then retested the proprioception of shoulder joints. We compared the proprioceptive changes of the shoulder with pre-fatigue test and post-fatigue test on the direction of shoulder movements. Results: There were significant differences of shoulder proprioception between pre-fatigue test and post-fatigue test of ARP in shoulder abduction and external rotation (p< 0.05). Conclusion: In our study, the proprioception of shoulder joint decreased more prominently on external rotation and abduction movements under severely provoked muscle fatigue around the shoulder joint.
