The noise in apartment buildings are major factor that determine the quality of indoor noise environment. Particularly, the noise from children's running footsteps and plumbing noise have caused the residents who live in decrepit apartment houses to uncomfortable environment. And as time go by, sound performance are getting worse according to the aging of the facilities. So this study deals with the plans to improve the sound performance of decrepit apartment house. To compare the noise reduction, we measured the heavy-weight impact sound level and plumbing noise level before and after changes the measurement conditions. As the results of measurements, the heavy-weight impact sound level were decreased when stiffness reinforcement were installed on slab. Especially the sound level were decreased 2.1-7.6dB in 50-80Hz of low frequency range. Instead of PVC pipe system, cast iron pipe and triple elbow drain pipe systems were installed. Noise level were decreased 15dB(A) in 250Hz. Noise level of pipe system's on the slab is less than under slab one. On the contrary water saving stool showed increasing the noise level.

For the last 40 years, the Korean government has built and supplied diverse public facilities. The Korean government, which has supplied diverse public facilities for the last 40 years, has maintained these public facilities as breakdown maintenance under limited budget. Because of increase of aging of public facilities and insufficient budget, it needs the total public facility maintenance. Especially, as Japan has also experienced similar issues and solved these, they are the introduction of P-FM theory and see successful examples. In this study, by comparison Analysis on the Merits and Demerits for Public Facility management (P-FM) between domestic and abroad, it would find a future direction to public facility management P-FM is to go.

Being dealt in Alfred Weber's Theory of the location of Industries, a lot of economic benefits can be obtained through aggregation and clustering of industrial facilities, which derived to the development of industrial complexes in Korea. However, with the IMF economic crisis as well as various institutional changes, the framework of aggregation and clustering of industries is broken, which led to individual developments that took place without any consideration of surrounding industries. For reformation of these condition of industrial complexes, national government-led regeneration projects are being carried out currently. However, national government-led projects mainly focus on profitable projects such as officetel and hotel that are irrelevant to exist composition of industrial complexes which is usually manufacturing base industries and are unable to solve the fundamental problems of industrial complexes. Thus, a necessity of industry clustering is deduced through case analysis of actual private-led manufacturing industry cluster with governance and analysis of benefits on financial, spatial and environmental aspects. In addition, implications on the necessity follow base on factorial analysis on the benefit of clustering development than individual development as well as analysis on the measures taken for successful clustering.

항만 리모델링을 위한 콘크리트 시설물에 대한 평가가 필요하며, 특히 리모델링이 결정된 경우에는 소파 블럭이나 케이슨 블록 등에 대한 재활용 여부를 평가하여 재활용이 가능할 경우에는 유용하는 것이 경제적인 리모델링에 도움이 될 수 있다. 이 연구에서는 콘크리트 항만시설물에 대한 건전성 평가 및 재활용성 평가를 위하여 기존의 초음파 속도법을 비롯하여 슈미트 해머를 이용한 반발경도법, 충격반향법, 표면파 속도법 등의 비파괴시험을 실시하였다. 국내 5개 항만에 대하여 비파괴시험 및 시편을 채취하였으며, 채취한 시편에 대한 압축강도 시험을 수행하여 비파괴시험 결과와 비교하였다. 비파괴시험결과와 압축강도 시험을 통하여 콘크리트 재료의 탄성계수와 압축강도 등을 평가하였다.

우리나라는 급속한 경재성장 및 도시화로 인해 도시지역의 건축물이 밀집되어 있다. 이러한 지역에서 화재가 발생할 경우, 강풍에 의한 불티의 비산으로 화재가 확대될 위험성이 존재한다. 하지한 현재 불티의 성상에 대한 모델 구축 및 연구가 부족한 실정이다. 본 연구에서는 일본 건축연구소(BRI)의 풍동 시설을 이용한 불티의 성상 실험을 통하여 비산모델을 구축하고 기존의 도시화재 시뮬레이션을 개선하였다.

This Study analyzed about various factors affecting preference of Silver Town. Especially, the Study shows how Individual peculiarities and the realization of decrepit Service and facilities have on preference of Silver Town. According to analysis, the site location, Economics and Safety have a positive effect on the preference of the Silver Town. On the other hand, Investment, pleasant environment and convenience have nothing to do with the preference of the Silver Town. Also, the Study shows that if someone realizes that medical service is the most important thing in the essential service, they prefer the Silver Town. If someone realizes that asset management service is the most important thing in the essential service, they don't prefer the Silver Town.

Korea rapidly arranged urbanization and overpopulation with high growth of economy and all kinds of decrepit facilities are scattered all over the downtown. If there is a strong wind in fire, fire is rapidly increased by various fire spread factors. And Korea cannot build prediction model of urban fire combustion phenomena because there is no studies that physically explains the suitable flame phenomena for its real state. In this study, based on the Japanese Urban fire simulation to target the traditional market area and suitability of fire risk assessment were reviewed.
