산업화 이후 연안지역을 중심으로 공업지역 등의 조성으로 많은 개발이 진행되어 왔다. 개발된 지역은 불투수 면적이 증가하고 연안지역의 특성상 하천으로 인한 수자원 공급과 더불어 지하수 이용량이 상대적으로 높게 나타나고 있다. 또한 기후온난화로 인해 해수면이 상승하고 있어 해수 침투는 점점 가속화되고 있다. 연안지역의 공업지대는 수자원 공급뿐만 아니라 해수침투로 인한 피해가 갈수록 증가할 것으로 보인다. 최근 해수침투에 대한 피해 방지를 위해 인공 주입 및 함양, 지하댐 등을 통해 지하수자원 관리에 대한 연구가 활발히 진행되고 있다. 이에 본 연구에서는 지하수자원 관리 기법 중 지하댐을 설치하여 해수침투를 방지하고 지하수자원을 확보하고자 한다. Visual MODFLOW를 이용하여 포항지역을 대상으로 지하댐을 적용한다. 지하댐의 설치 방법에 대해서도 다양한 시나리오를 이용하여 효과 분석을 실시한다. 이를 이용하여 지속가능한 지하수자원 관리를 도모하고자 한다.

The land use has been changed artificially and caused the result of temperature increase of city compared with the outside of city or region of park and forest. The purpose of this research is to analyze the change of the urban surface temperature with land use zoning in Jinju using Landsat TM/$ETM^+$ imagery and to provide the correlation between NDVI(Normalized Difference Vegetation Index) and urban surface temperature change. The results presented that the spatial distribution of urban surface temperature was depending on the change of NDVI values on land use zoning. Considering to the average temperature by land use zoning, industrial area was the highest temperature but green area was the lowest temperature. Also as a result of comparing the correlation between surface temperature and NDVI, the green and residential area had higher correlation values than the commercial and industrial area. These results will be played a part as one of the major factors for implementing the sustainable urban planning considering the urban heat island effect problem.

본 연구에서는 공업지역의 비점오염저감시설을 설계하는 방안이 제안된다. 처리대상구역의 SS 배출부하량은 최근 국립환경과학원에서 제안하고 있는 원단위를 기반으로 산출된다. SWMM을 이용하여 처리대상구역의 SS 배출부하량을 모의한 뒤, 비점저감시설로서 생태저류지를 설치하여 설계용량에 따른 비점저감효과가 정량화된다. 다양한 모의결과를 바탕으로 생태저류지 설계용량에 따른 SS의 삭감대상부하비가 유도되며, EPA 기준에 따른 생태저류지의 SS 저감효율이 산정된다.

Some Feral Pigeons Columba livia were collected in commercial, industrial, park and resident areas of Seoul and heavy metal concentrations in their liver, kidney, bone and muscle tissues were measured to compare the levels of exposure by habitats. Statistical analyses showed some differences in the levels of heavy metals among these habitats. The levels of iron in liver and zinc in kidney were lower in resident area than in the other ones. Manganese and copper levels in all tissues were the highest in industrial area and park area, respectively. Lead bone level in resident area was the lowest, while that in commercial area was the highest. Cadmium level in kidney was higher in park area than in the other areas. Of these results, the levels of iron, zinc and lead in some tissues were related to traffic density in each habitats.

The industrial areas including large industrial complexes formed by the process of the growth-oriented industrialization in the past have been attributed to worsening the urban competitiveness of cities due to their infrastructure shortages and aging. Government-led regeneration projects for old industrial complexes have been implemented on a trial basis, but there is a problem with applying a uniform regeneration planning to all the regional industrial complexes with different circumstances and physical environments. In this context, this study diagnosed the social conditions and physical characteristics of the Sasang industrial area in the city of Busan formed by private-led projects in the past and then tried to suggest its regeneration directions. The study area was characterized as its weakening industrial function, infrastructure shortage, and increasing development pressure. Based on these regional characteristics, the regeneration directions were suggested. In the planning phase, pubic-led infrastructure expansion is first needed and urban renewal needs to be applied to some areas designated as priority maintenance areas. In the implementation phase, stepwise projects are required in the medium to long term and it is important to build upon the consensus with private companies through establishing collaborative governance.

In Korea, the minimum separation distance between aboveground high-pressure natural gas pipeline and buildings is regulated by Korea gas safety (KGS) code. In this paper, The technical backgrounds for the revision of the KGS code related to the minimum separation distance was presented. A consequence-based approach was adopted to determine the minimum separation distance by a reasonable accident scenario, which was a jet fire caused by the rupture of one inch branch line attached the gas pipeline. Where, the higher thermal radiation flux threshold was selected for workers in industrial area than for people in non-industrial area, because the workers in industrial area were able to escape in a shorter time than the people in public. As result of consequence analysis for the accident scenario, we suggested the KGS code revision that the minimum separation distances between high-pressure natural gas pipeline installed above ground and buildings should be 30 meter in non-industrial area and 15 meter in industrial area. The revised code was accepted by the committee of the KGS code and now in effect.

To monitor the heavy metal exposure conditions of Feral Pigeons Columba livia, we collected them at commercial area, industrial area, park area and resident area in Seoul. In feathers, iron concentrations were significantly different among habitats(ANOVA, p<0.05), and were the highest at park area. Manganese concentrations were relatively higher at industrial and park area than other areas(ANOVA, p<0.05). In case of copper levels were the significantly highest at park area(ANOVA, p<0.05). Zinc, lead and cadmium had no difference among habitats. Correlation between livers and feathers concentrations were highly significant to copper(r²=0.983, p<0.01) and cadmium(r²=0.632, p<0.01), but iron, zinc, manganese and lead were not significantly different.
