This paper presents algorithm to plan construction and expanding of substation considering contingency accidents by proposing utilization factor according to configuration of substation bank system. In this paper, firstly, proper sphere of supply area by each district which could be standardized with respect to its supply capacity is established under assumption of long term load forecasting. Secondly, goal of utilization ratio based on configuration of substation bank was set to keep reliability by remaining sound bank when it happen to one bank accidents. Finally, it is set up for optimal construction and expanding of substation considering economy and reliability simultaneously about substation to exceed these ratio. To verify proposed algorithm, at first, after adopting a part of Kangnam area in Seoul as area for testing, it is divided into several regions for this area according to power branches of power utility. Secondly, by deriving correlation factor between load demand and economic indicators in these region respectively, the regional load forecasting was performed with economic growth and city plan scenario. Finally, based on the predicted load demand by region and land use data which is identified from air-photographic, the load demand by district was predicted. Also, planning for substation considering contingency is formulated to expand taking into account computing utilization factor which is based on configuration of substation bank respectively.

Massive underground excavation can be carried out recently due to the technical development of the excavation for retaining wall. Feed-back analysis using field measurement results is recommended to secure the stability of the construction because calculated values at stages of the design and the construction are uncertain. Reinforcement plan should be established based on the result of it. This study deals with the underground excavation site, which is under construction and is close to structure(subway) at downtown area. The result of feed-back analysis on the measurement data of displacement at multi-soil layers was reflected to make a plan for safe construction. This case study can be useful information for contingency plan on abnormal displacement which can be occurred at similar underground excavation.

Objectives : This study presents a scientific basis for the establishment of an environmental health contingency plan for dealing with accidental coastal oil spills and suggests some strategies for use in an environmental health emergency. Methods : We reviewed the existing literature, and analyzed the various fundamental factors involved in response strategies for oil spill. Our analysis included data derived from Hebei Spirit oil spill and used air dispersion modeling. Results : Spill amounts of more than 1,000 kl can affect the health of residents along the coast, especially those who belong to vulnerable groups. Almost 30% of South Korean population lives in the vicinity of the coast. The area that is at the highest risk for a spill and that has the greatest number of people at risk is the stretch of coastline from Busan to Tongyeong. The most prevalent types of oil spilt in Korean waters have been crude oil and bunker-C oil, both of which have relatively high specific gravity and contain volatile organic compounds, polycyclic aromatic hydrocarbons, and metals. In the case of a spill of more than 1,000 kl, it may be necessary to evacuate vulnerable and sensitive groups. Conclusions : The government should establish environmental health planning that considers the spill amount, the types of oil, and the distance between the spot of the accident and the coast, and should assemble a response team that includes environmental health specialists to prepare for the future oil spill.

지속적인 산업화와 도시화에 따른 에너지 수요의 급증으로 인해 원유와 석유제품의 해양수송이 점점 증가하고 있다. 우리나라의 경우 국내의 유류 수요를 맞추기 위해서는 매일 30만톤급의 대형 유조선이 입항해야 하기 때문에 대형 유류오염 사고에 노출되어 있다 해양 유류오염사고의 가능성을 줄이기 위해 부단한 노력에도 불구하고 회복하기 어려운 유출 사고는 인간의 실수, 악천후 또는 복합적인 이유로 일어나게 된다. 따라서 적절한 대응시스템으로 지역방제계획을 세워 최악의 경우에 대비하고 해양환경과 연안자원을 보호해야만 한다. 특히 보호의 우선순위를 명확히 하고 현장 방제전략을 세움으로써 유출과 방제의 노력이 환경에 미치는 영향을 줄이기 요구되는 방제정보지도에 초점을 맞추었다. 본 논문에서는 기름에 대한 민감도의 정의와 개발한 소프트웨어의 주요특짚과 함께 방제정보지도를 간략히 소개한다.

오늘날 주민 생활공간과 인접해 있는 산업단지의 노후화 문제는 지역사회 안전을 위협하는 원인으로 지적되고 있다. 본 연구에서는 현행의 위험도 분석 및 지역사회 고지범위를 제고하기 위해 대안의 사고시나리오의 영향범위와 계절별 기상 최빈값을 활용하여 모사된 영향범위를 비교 분석하였고, 시간대별로 관측된 풍향을 계절별로 검토하여 독성물질 누출 시 피해 가능성이 높은 지역을 예측하였다. 또한 인명피해를 최소화하기 위한 한계 대피시간 및 최소 이격거리를 제시하였으며, 비상대응에 활용되고 있는 위해관리계획서를 고찰하여 인근 근로자 및 주민에 대해 한층 더 합리적인 안전대책이 이루어질 수 있도록 제언하였다.

The goal of the present research was to develop a mean to determine indices of drought warning and emergency necessary to manage drought and establish water supply contingency plan for the municipal and industrial water supply system in urban areas. To do this, we worked on the Sayun catchment which is the main water source of Ulsan and used measured hydrologic data (storage, inflow, supply, outflow) from 1980 to 1996. The indices of drought calculated by the method of Phillips drought index based only on monthly precipitation do not pertinently represent drought phenomena in case water supply is from dam or reservoir in an urban area. Therefor, we developed the drought index technique including inflow, storage, outflow and supply which are the chief factors of drought management. The result showed that the method of Phillips drought index considering the capacity of water supply was excellent when applied to practical drought phenomena.

The purpose of this study is to examine farmers' intentions, attitudes, and the type of filming they are involved in, including to provide supporting data for planning the agricultural strategy and Green Belt policy in Seoul. All the collected data was analyzed using the contingency tables and the Chi-square test using the SAS computer statistical package. The leaseholders did not want to change the current Green Belt policy for the study area, while the landowning farmers hoped for either its revision or dissolution. Both groups pointed out that the Green Belt policy resulted in the delay of development and complained about the difficulty of changing the land use type. The older generation supported the dissolution of the Green Belt, policy, as compared with the younger generation who wanted to maintain or modify the policy. The leaseholders worried that the possible changes in the Green Belt policy might affect the current agricultural land contract system, whereas the landowning farmers were very interested in easing restrictions on changing land use. The compensation plan, which is indemnified land owners for their loss of restrictions on land use, might be useful to sustain urban farming in the Green Belt.
