여름철 국지성 집중호우 및 태풍으로 인한 피해가 빈번하게 발생하고 있으며, 산지가 많은 국내에서는 산지지역 뿐만 아니라 도심지에서의 토석류 피해 또한 급증하고 있다. 2011년 집중호우로 인해 서울시 서초구에 위치한 우면산에서 동시 다발적으로 많은 토석류가 발생하였고 이로 인해 많은 인명과 재산피해가 발생하였다. 규모면에서 보다 큰 토석류가 이전에 강원지역 등에서 발생하였음에도 불구하고 우면산 산사태가 사회적 관심을 일으킨 것은 서울 도심지에서 발생하였기 때문이다. 이러한 토석류로 인한 피해를 줄이기 위해서는 토석류를 유발시키는 강우의 해석이 먼저 선행되어야 하며, 토사유출모의 결과의 확산면적의 정확성이 중요하다고 판단된다. 따라서 본 연구에서는 도심권(서초구 우면산) / 비도심권(춘천 마적산)을 대상지역으로 선정하였으며, 분포형 강우-유출모형인 S-RAT을 이용하여 빈도별(30년, 50년, 100년, 200년, PMP) 토석류 유발 강우를 산정하고, 토석류 2차원 수치모형인 RAMMS를 이용하여 정량지수(Quantitative index)분석을 통해 최적의 매개변수를 산정하였다.

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.

도심지역의 중금속 배출원은 매우 다양하며, 배출 중금속은 물질별 노출 수준, 노출기간에 따라 건강유해영향을 일으킬 수 있다. 따라서 직업적 노출이 없는 도심 지역의 일반인의 혈중 중금속의 모니터링은 독성학적 측면에서 중요하다. 본 연구는 서울 도심지역의 직업적 노출이 없는 성인 남녀 144명(20∼75세)을 대상으로 중금속(납, 크롬, 니켈, 카드뮴)의 혈액 내 축적된 정도를 평가하였다. 채취한 혈액의 분석은 GF-AAS를 사용하였다. 물질별 혈중 중금속 농도는 납 63.2 $\mu\textrm{g}$/L, 크롬 0.12 $\mu\textrm{g}$/L, 니켈 $\mu\textrm{g}$/L, 카드뮴 1.43 $\mu\textrm{g}$/L로 각각 조사되었다.

The purpose of this paper is to investigate office location dynamic in Seoul and to analyze comparatively the office activities of emerging office centers. Since mid 1980s, the expansion of office employment and spatial differentiation of the office-type jobs have changed the employment and spatial structure of Seoul. The major employment centers are CBD, Kangnam district and Youido. Among these, CBD and Kangnam have developed as the two leading centers of Seoul. Youido, the typical office-oriented center, shares CBD functions especially specializing security business. Selective decentralization of offices made qualitative differences among the centers. In spite of vigorous office decentralization, CBD has kept the principal offices of finance and insurance, travel agencies, advertising agencies, management consulting firms, major public institutions and headquarters of upper 100 companies in Korea. But the offices of producer services such as law, architects, engineering and computer consulting and real estates and headquarters of upper 5000 companies in Korea have been decentralized dominantly to Kangnam.

The purpose of this study was to understand changes in Seoul's downtown planning from the 1960s to 1990s. The approach was examined by classifying its formation process though urban conservation. The effects of modernization and urbanization on Seoul's downtown planning were as follows. In the 1960s, Seoul attempted to decentralize urban functions due to excessive population. In the 1970s, a policy to diversify urban functions according to Gangnam development was enacted. In the 1980s, the existing downtown declined, and the sub-downtown grew with changing urban functions. In the 1990s, the identity of the existing downtown was recognized through the Seoul Memorial Project. This study also analyzed downtown planning efforts concerned with urban conservation. First, the physical aspects of existing buildings and street facilities were maintained. Second, the spatial aspects for the maintenance of surrounding areas were proposed. Fourth, the social aspects for accessibility by Seoul citizens was improved. This analysis demonstrates the concept of urban conservation based on physical-spatial-social aspects.

아직도 대한민국 인구 중 5분의 1이 사는 서울 안에는 국민의 건강을 책임지는 젖줄, 아직까지 극히 소수의 낙농목장이 존재하고 있다. 도시근교의 축산도 타지역으로 밀려나고 있는 추세에 서울 안에서 낙농을 영위하기란 거의 불가능한 일, 확실히 서울은 낙농의 불모지이다. 비록 그린벨트 지역으로 분류되어 있지만 행정구역상 서울시 내에서 대가축인 젖소들이 사육되고 있다는 점 만큼은 이채로운 사실이다. 서울을 비롯한 수도권지역이 지속적인 발전의 모습을 띤 지역이고 보면, 여전히 존속하여 과거 낙농의 모습을 유지해나가고 있는 이들 목장은 한국낙농의 '화석'이라 불러도 좋겠다. 금번 월간낙농육우 3월호에서는 이들 목장 중 두곳을 방문하여 그들의 목장생활과 애로를 들어봤다.

In order to compare the lead and cadmium levels, studies of heavy metal accumulation of feral pigeons from rural (Deokjeok island), central urban (Seoul city), and industrial complexes (Ansan, Busan, Ulsan, and Yochon) were conducted. The outstanding result of this study is that feral pigeons in urban and industrial complex areas contain high Pb and Cd concentrations in kidney, bone, liver, and lung tissues compared to those of rural areas. Such a trend was prominent in the target organs, bone and kidney, about 10 times greater than in rural areas. On the other hand, the lead levels of the Yochon Industrial Complex were noticeably lower than those of other industrial complex areas. Not only feral pigeons habit of street and ground feeding, but also atmospheric metal concentration offers an explanation for the heavy metal concentration differences in the study areas.

The purpose of this study is to develop transportation-sensitive land use densities in a metropolitan context. It analyses traffic impacts according to 20 different development density scenarios in the downtown Seoul, and estimates the density ceiling. The results identify that the transportation-wise sustainable density in the downtown can be extended up to the FAR level of 460% with an option of 2,000 won congestion charge levied on the downtown area. It also finds that the region-wide sustainability measured by congestion level can be improving as the level of congestion charge increases. Without the congestion charge, however, the density ceiling slides down to 430%. It is recommended that, in order to bring in higher density developments in the region, transportation demand management (TDM) measures are indispensible.
