자연재해는 지역사회 전반에 극심한 스트레스를 발생시킨다. 다수의 경우 시간의 흐름에 따라 충격을 극복하지만, 일부는 PTSD와 같은 장기적인 정신적 피해를 경험하게 된다. 이에 재난과 심리적 충격에 관한 연구가 진행되고 있지만, 여전히 부족한 수준이다. 자연재해는 시설 붕괴, 인명피해 등 다양한 피해를 야기하기에 피해자가 경험하는 피해의 종류가 다르며, 경험하는 상실의 정도에도 차등이 있다. 특히 자연재해로 인한 가장 흔한 피해인 주택파손의 경우 피해자가 경험하는 충격은 매우 크다. 따라서 본 연구는 자연재해로 주택이 파손된 가구가 경험하는 심리적 충격을 확인하고, 추적연구를 통해 심리적 충격이 변화하는 특성을 확인하고자 하였다. 연구 결과, 주택이 파손된 경우 심리적 충격이 더 크게 나타나 주택의 파손으로 인한 심리적 충격이 다른 피해로 인한 충격보다 더 큰 것을 확인했다. 또, 재난으로 인해 발생하는 심리적 충격이라고 할지라도 불안, 우울, PTSD 그리고 전반적인 심리적 충격 등 그 성격에 따라 변화 양상에 영향을 미치는 요인이 다른 것으로 나타났다. 그 중, 보건의료 서비스는 모든 변수에서 유의하게 분석돼 재난 이후 안전과 관련된 기본서비스의 제공이 가장 필요로 된다고 해석된다. 또, 재난구호서비스 중 심리 안정 지원은 불안, 우울과 같은 단기적인 충격에는 긍정적인 영향을 미치나, 심리적 영향이 가중된 PTSD에서는 오히려 역효과를 보여 심리지원체계의 변화 및 발전이 요구된다고 할 수 있다.

As urbanization proceeds and therefore impervious surface coverage increases, the amount of runoff goes up and the hydrological cycle is also changed. The surface retention and interception of precipitation in the urban area are reduced because the surface area is now slick and solid. Increasing runoff in building areas of the city causes flood damage, water pollution, reduction of ground water recharge, and the other environmental problems. This paper investigates various techniques of increasing rates in a site development performed by Berlin. The techniques offered in this paper improve sit water balance, and thus keep the site ecosystem much healthier.

The rental housing has played a key role to supply a decent living space for the low-income households. The owner of the rental housing should maintain and manage the building physical condition. On the other hand, rents should use the housing without any damage and pay a certain fare for the rent. A rent is classified into two types : private and public. The public rent is mainly to supply a living space for non-available home owner with a low-rent fare. Many of public rent are built and supplied by the public institution or local government. The supplier would take a responsibility to maintain the building and components, reflected by the maintenance plan and repair scope. In this paper, it aimed at providing the repair time in building components of the public rental housing such as lighting, electrical cable, paintings and etc.. The repair time is analyzed with three calculation methods which are solved by the probability and empirical approach. Results are as follows : First, the repair time of the electrical facilities are maintained with 11yr, 10yr and 7 in permanent, public and redevelopment rent respectively. The roof proof has a repair time with 14yr, 11yr and 8 in permanent, public and redevelopment rent housing respectively. Second, Most of the components has a prior length of the repair time in permanent, public and redevelopment rent sequently. There is a difference in repair time according to the rental types. Therefore, it would continue to research the difference in aspect of the living style, building physics, living consciousness and etc.

Since public facilities have high property values and are directly exposed to the flood hazard, they account for the highest share of disaster damages compared to other assets such as housing, industry, vehicle and agriculture in case of floods. Therefore, this study was conducted to develop and suggest the potential flood damage index for public facilities to evaluate potential flood damage of specific local government directly or indirectly as a tool for decision-making related to flood prevention, maintenance, management, and budget allocation. The flood damage assessment system proposed in this study was evaluated in 231 local governments nationwide. Evaluation results showed that higher values were obtained in Seoul metropolitan government, Gyeonggi-do (province), coastal areas in Gyeongsangnam-do (province), and Jeju island.

Recently we suffered lot of failures of polymer surge arresters made by same manufacture after one year field operation. In order to set up countermeasures we investigated the causes of failures. We extracted faulted arresters and sound ones which were installed in same pole with faulted ones for the electrical test and dissection. 44 arresters were removed from 8 branch offices. Almost all of faulted arresters hadtracking damage on the interface between inner module and housing and the surface of inner module was very rough and irregular. It was possible to occur moisture ingress into the interface between inner module and housing due to the void of the interface and non tight sealing caps. Lots of sound arresters were failed during the moisture ingress test. This result must relate with tracking damage of faulted arresters. Therefore we can say that arresters had poor interface and sealing system. But we could not found aging and defects of ZnO elements because the electrical performance except moisture ingress test of arresters showed good.

This study analyzed the physical characteristics and change characteristics of urban detached residential area. In the reality of South Korea in which the history of modern urbanization is not long, the densification that progressed together with sudden population growth without any consideration of city plans became to reveal many problems. Thereafter, apartment-centered large scaled development plans have been implemented until now as an alternative for the foregoing. As the residential environments of old downtown areas that were excluded from the development have been gradually deteriorated, large scaled re-development and reconstruction projects have been adopted as ways to solve the problems of the old downtown areas. On one hand, the development methods that damage the history of the detached housing areas have been resisted. With such a background, this study attempted the analysis of the change characteristics of the Kookmin Housing Complex in Suyu 1-dong, Seoul with a view to playing the role of evidentiary materials for the disappearing urban detached housing areas or those urban detached housing areas that may be revived. This author hopes and the results of this study will lead to careful development that presents measures to maintain and develop modern urban residential areas where the history of past residential areas and culture are disappearing due to full-scale redevelopment.

The purpose of this study is to evaluate the safety of a wire connector fabricated for the effective installation of a lighting fixture including its contact resistance, insulation resistance, withstanding voltage characteristics, etc., and to provide the basis for the analysis and judgment of PL(Product Liability) dispute by presenting a damage pattern due to a general flame and overcurrent. This study applied the Korean Standard (KS) for the incombustibility test of the connector using a general flame and performed an overcurrent characteristics test of the connector using PCITS (Primary Current Injection Test System). The contact resistance of the housing connector was measured using a high resistance meter and the insulation resistance was measured using a multimeter. In addition, a supply voltage of AC 1,500V for testing the withstanding voltage characteristics was applied to both ends of the connector. Measurement was performed on 5 specimens and the measured values were used as a basis for judgment. Since the connector is fabricated in the form of a housing, it can be connected and separated easily and has a structure that allows no foreign material to enter. In addition, since it has a structure that allows wires to be connected only when their polarity is identical, any misconnection that may occur during installation can be prevented. When the incombustibility test was performed by applying a general flame to the connector, it showed outstanding incombustibility characteristics and the blade and blade holder connected to the housing remained firmly secured even after the insulation sheath (PVC) was completely destroyed by fire. In addition, the mechanism of the damaged connecting wire showed a comparatively uniform carbonization pattern and it was found that some residual melted insulation material was attached to both ends. In the accelerated life test (ALT) to which approximately 500% of the rated current was applied, the connector damage proceeded in the order of white smoke generation, wire separation, spark occurrence and carbonization. That is, it could be seen that the connector damaged by overcurrent lost its own metallic color with traces of discoloration and carbonization. The contact resistance of the connector at a normal state was 2.164mV/A on average. The contact resistance measured after the high temperature test was 3.258mV/A. In addition, the insulation resistance after the temperature test was completed was greater than $10G\Omega$ and the withstanding voltage test result showed that no insulation breakdown occurred to all specimens showing stable withstanding voltage and insulation resistance characteristics.
