Coastal cities need disaster planning that accounts for the complex causes of environmental disasters such as high tides or tsunamis generated by typhoons, and of river or lowland flooding caused by heavy rains, etc. The elements of the disaster map were initially defined using a Geographic Information System (GIS) to allow for efficient information management. Complex disaster information elements were thus established in this study to create a disaster map of coastal cities. The range of information required for coastal cities includes the type of disaster, evacuation methods, available sheltering facilities, and learning content. These informational elements are intended to build on spatial information based on data available from the Ministry of Public Safety and Security as well as local governments.

Roads in Korea can be classified into four types according to their responsible authorities. For example, Motorway is constructed, managed, and operated by the Korea Highway Corporation. Ministry of Construction and Transportation is in charge of National Highway, and Province Roads are run by each province government. Urban/county Roads are run by corresponding local government. This study analyses the trends of road accidents for each road type. For this purpose, the numbers of accidents, fatalities, and injuries are compared for each road type for last 15 years. The result shows that Urban/County Roads are the most dangerous, while Motorways are the safest, when we simply compare the numbers of accidents, fatalities, and injuries. However, when we compare these numbers by dividing by total road length, National Highway becomes the most dangerous while Province Roads becomes the safest. In the case of road accidents, fatalities, and injuries per vehicle km, which is known as the most objective comparison measure, it turns out that National Highway is the most dangerous roads again. This study also developed time series models to estimate trends of fatalities for each road type. These models will be useful when we set up or evaluate targets of national road safety.

1960년초 이래 우리나라는 고도의 경제성장을 이룩하게 되었으며 이러한 경제성장에 따른 산업화 사회의 특징인 공업화 도시화 인구집중 현상은 우리나라에도 심각한 환경오염 문제를 야기시켜 왔다. 또한 같은 기간동안 자동차의 보유대수 역시 급격한 증가를 보여왔던바, 1962년 30,000 대에서 1982년도 자동차 등록대수는 약 640,000대로 증가하게 되었으며 대부분의 자동차가 대 도시에 집중되어 있다. 특히 전체 차량의 40%가 집중되어 있는 서울시의 경우에는 자동차 배 출가스로 인한 대기오염문제가 도시민의 건강과 재산에 많은 피해를 일으키게 되었다. 우리나 라는 선진 외국의 대도시에 비해 자동차의 1일 주행거리가 3배 내지 5배를 더 주행하고 있고 자동차 배출가스 기준의 완화, 노후차량의 증가, 도로율의 불황 및 도로조건의 불비 등은 도시 중심천의 자동차 집중현상과 함께 자동차 배출가스로 인한 대기오염 문제가 보다 더 심각하게 우려되었고, 따라서 자동차 배출가스규제 강화의 필연성이 계속해서 주장되어 왔다. 자동차로 인한 공해문제는 1940년도 후반 미국 남부 California 지방에서 광화학스모그의 발생과 함께 거 론되기 시작하였으나 본격적으로 문제가 제기된 것은 급격한 자동차 증가로 인한 도시민의 건 강피해가 발생하기 시작한 것은 1960년대이다. 처음으로 규제되기 시작한 것은 1965년 미국에서 "자동차 오염방지법"의 제정부터이며 1968년부터 자동차 배출가스에 대한 규제가 시작되었다. 한편 일본은 1973년, 유럽에서는 1975년부터 일산화탄소, 탄화수소, 질소산화물 및 매연에 대한 규제를 시작하게 되었다. 우리나라에서는 "도로운송차량법"에서 도로교통의 안전과 질서유지라는 측면에서 일부 규제하여 오다가 1977년말 "환경보전법"이 제정 공포되면서 1980년 1월 환경정의 발족과 함께 실제로 자동차 배출가스를 규제하게 되었다.발족과 함께 실제로 자동차 배출가스를 규제하게 되었다.을 SUP7H종으로 더욱 향상된 것이 실용 화되고 있다. 아래에서 이에 대한 기계적 특성을 중심으로 검토키로 한다.9%내인 0.07cm 정도였으나 1973년과 1974년의 방축년에는 조차 3개 처리구(3.4-5.18cm)에 필적되는 연평균 4.16cm로 나타났다. 5. 전체 시험구로부터으 연평균 토양유실량은 Sharpsburg 점질양토에 대한 S.C.S 한계허용치 10ton/ha/year 이내로 나타났다. 비처리구에서의 토양유실량은 평균 2.56ton/ha/year로 높게 나타난 반면 3개의 서로 다른 추리구인 비수구, 초생수로구 및 Bromegrass구에서는 각각 0.152, 0.192 및 0.290ton/ha/year로 낮은 결과를 가져왔다. 6. 평균 침전량에 대한 L.S.D. 검정 걸과 전시험구중 비처리구가 고도의 유의차를 나타낸 반면 비수구, 초생수로구 및 Bromegrass 목초구 간에는 아무런 유의차가 인정되지 않았다. 7. 농지보전 처리구인 배수구와 초생수로구는 비처리구에 비해 낮은 침두 유출량과 낮은 토양유실량을 나타내었다.구보다 14% 절감되는 것으로 나타났다.작용하는 것으로 사료된다.된다.정량 분석한 결과이다. 시편의 조성은 33.6 at% U, 66.4 at% O의 결과를 얻었다. 산화물 핵연료의 표면 관찰 및 정량 분석 시험시 시편 표면을 전도성 물질로 증착시키지 않고, Silver Paint 에 시편을 접착하는 방법으로도 만족한 시험 결과를 얻을 수 있었다.째, 회복기 중에 일어나는 입자들의 유입은 자기폭풍의 지속시간을 연장시키는 경향을 보이며 큰 자기폭풍일수록 현저했다. 주상에서 관측된 이러한 특성은 서브스톰 확장기 활동이 자기폭풍의 발달과 밀접한 관계가 있음을 시사한다.se that were all low in two aspects, named "the Nonsignificant group".

Road classification system is the first step for determining the road function and design standards. Currently, roads are classified by various indices such as road location and function. In this study, we classify road using various traffic indices as well as to identify traffic characteristics for each type of road. To accomplish the objectives, mixture model was applied for classifying road and analyzing traffic characteristics using traffic data that observed at permanent traffic count stations. A total of 8 variables were applied: annual average daily traffic(AADT), $K_{30}$ coefficient, heavy vehicle proportion, day volume proportion, peak hour volume proportion, sunday coefficient, vacation coefficient, and coefficient of variation(COV). A total of 350 permanent traffic count points were categorized into three groups : Group I (Urban road), Group II (Rural road), and Group III (Recreational road). AADT were 30,000 for urban, 16,000 for rural, and 5,000 for recreational road. Group III was typical recreational road showing higher average daily traffic volume during Sunday and vacational periods. Group I showed AM peak and PM peak, while group II and group III did not show AM peak and PM peak.

기후변화에 따른 빈번한 태풍과 집중호우로 인해 지속적으로 피해규모가 증가하고 있으며 점차 다양한 지역에서 피해가 나타나고 있다. 과거 태풍 루사나 매미의 경우 도시유역에서 주요 피해가 발생하여 대규모 피해를 야기하였으나 2006년 발생한 태풍 에위니아의 경우 집중호우로 인한 배수문제, 산사태로 인한 토석류 발생과 이에 따른 도로 및 하천 유입으로 피해가 나타났다. 이러한 피해는 남해안 및 영남지방, 강원 영서지방에서 주로 발생한 것으로 과거 피해 유형과 차이가 난다. 기존 하천 중심의 치수대책만으로는 다양한 지역특성을 고려한 치수계획을 종합적으로 수립할 수 있는 한계가 발생하며 이에 따라 국토해양부(2001)는 수자원 장기종합계획에서 하도와 유역 시스템을 함께 고려하는 유역종합치수정책을 제안하였다. 홍수피해잠재능은 수자원장기종합계획(2001)에서 처음 제시된 개념으로 면 개념을 도입하여 공간적 비교가 가능하고, 단위구역의 치수특성 및 사회경제적 가치를 평가할 수 있도록 개발된 지수(이승종, 2006)이며, 치수안전도 설정을 위한 가장 중요한 개념으로 활용되고 있다. 그러나 최근에 제시된 개념으로 아직 이론적 기반이 미흡하며 지속적인 연구를 통해 수정된 개념이 제시되고 있는 실정이다. 본 연구에서는 유역종합치수계획 등 국가 치수정책을 수립하기 위해 중요한 개념인 홍수피해잠재능과 치수안전도의 치수계획 활용 사례를 조사하여 지역특성별로 유역분할기법을 조사 정리하였으며 국외 사례를 분석하여 유역분할기법의 발전 방향을 제시함으로써 유역단위 맞춤형 치수계획 수립을 위한 기초 자료를 제공하고자 한다.

Urban centers have been recognized as problem regions so far. However, urban centers of metropolises take a new aspect in recent years as much as the negative influence of gentrification becomes a social issue. This paper analyzes the declining trend of urban centers in six metropolises - Seoul, Busan, Daegu, Incheon, Gwangju and Daejun from 1995 to 2010. As results of analysis, it is identified that the urban centers' shrinkage got moderated recently in the metropolises, even though their resurgence is not evident. Especially it is difficult to say longer that Jongro-Gu and Jung-Gu of Seoul are declining urban centers. Easing shrinkage is most outstanding in Jung-Gu, Daegu among local metropolises. Nevertheless, a serious obstacle such as high price of housing is in the process of obvious resurgence of urban center differently from the United States, Europe and Japan.

This survey was conducted to investigate about purchasing, use and management of cooking oil, and the intake amounts of each food and fats & oils from each food on 296 housewives in a big city, medium and small city, farming village, fishing village, and mountain village from June 5 to July 20 in 1987. The percentage and $x^2$-test were used in data analysis and the arithmetic mean of the gross intake divided by the total subjects gave the intake amounts per capita per day. The results of this study are as following; 1. Purchasing and keeping of cooking oil. The reading ratio of label in purchasing cooking oil was high among housewives of cities and highly educated housewives. There were dissatisfactions about quality (46.7%), price (33.7%), and packing (19.5%) after purchasing cooking oil. Cooking oil was being kept mainly in glasses (64.7%) or in synthetic plastics (31.5%), and also in dark & cool places. 2. Use and refining of cooking oil. More housewives (70.6%) kept cooking oil used once in a different container after filtering. The housewives re-using used oil after adding new oil to it were only 30.0%. There were a lot of housewives frying foods twice or three times in the same oil. 3. Intake of fats & oils and foods containing fats & oils. Average intake amounts of food containing fats & oils per person per day was 6.85g in fats & oils, 42.96g in meat & its products, 95.13g in fishes & shellfishes, 22.89g in eggs, 60.69g in legumes & its products, 61.00g in milk & milk products, 4.22g in seeds & nuts, and 9.36g in instant noodles. Average intake amounts of fats & oils per person per day taken from these foods was 6.4g from fats & oils, 2.3g from meat & its products, 4.3g from fishes & shellfishes, 2.7g from eggs, 3.0g from legumes & its products, 2.5g from milk & milk products, 1.8g from seeds & nuts, and 1.7g from instant noodles.

This paper aims to interpret the transformation process of town plan of Gosan-up(高山), which was provincial administrative focus town in Josun dynasty, basing on morphological viewpoint. Morphological concepts, such as morphological frame, urban plan, kernel, colonization, route system, fixation line, fringe belt, plan unit & plan division, morphological period derived from the study of Conzen, M.R.G. and Caniggia, G. epidome district, break point, broken plot, urban fallow, privatization are adopted for the interpretation of urban form. Morphological period of Gosan can be divided in four ; formation of kernel & morphological structure, disintegration & redevelopment of the kernel, augmentative development of the kernel & formation of modern epidome district, outwards expanding of urbanized area, transition & reorganization of epidome district. Especially public leading projects such as construction of new regional connection road and public facilities such as myeon(township) office, agricultural cooperatives federation office, market, are main factors of morphological transformation of townplan. In the early stage, under the Japanese imperialism, construction of the new matrix route(Gosan-ro) through the kernel and followed planned routes gave way to disintegrating traditional areal plan unit and forming small block plan units in administrative facilities area. And linear plan units with commercial buildings were formed along the new matrix route and planned route adjacent to periodical market. In the latter stage, with development of public facilities, private sectors' large circulation institution and terminal outside the kernel with planned routes formed areal block based plan units with commercial and public buildings. And part of the spatial area with the linear plan unit were turned into urban fallow. With the transformation of town plan, new roads outside the kernel have substituted for traditional fixation line of waterway with road and topographical feature. Fringe belts were made successively along the new road and around the major intersections outside of existing urbanized area. Land use in fringe belts, constituting of outer locational tendency early on formation, was gradually replaced with commercial & business buildings.
