  • 본 논문은 주민 불편과 민원, 소음관련 소송, 이에 따른 정부의 막대한 재정적 부담 등 도시화 및 국민소득의 향상에 따라 악화될 것으로 전망되는 민간공항주변 소음지역 내 제반 문제에 대한 항구적 대응책으로서 공간계획적 접근 방안을 제안하였다. 1990년대 중반 이후 우리정부는 민간공항주변 소음지역 문제점에 대처하기 위하여 행위제한을 근간으로 하는 소음지역 관리방안과 피해주민에 대한 개별적 보상 위주의 소음대책사업을 전개해왔다. 하지만 지금까지의 소음대책 방안은 급격한 도시화에 따른 개발압력을 효과적으로 관리하고 소음지역 내 공항 및 소음친화적 적정기능 및 시설을 입지시키는 데 그 한계를 보여 소음대책지역이 확대 재생산되고 있다. 또한 임시방편적 성격의 소음대책사업에 대한 주민만족도 저조로 소음과 관련된 민원 및 소송은 기하급수적으로 증가할 전망이다. 따라서 미국과 영국의 공항주변 소음지역 관리사례를 바탕으로 소음대책사업의 다양화와 섹터개념을 도입한 공간계획적 관리체계의 도입, 이를 위한 공공기관의 긴밀한 협력을 주된 내용으로 하는 국내 민간공항주변 소음지역관리 개선방안을 제안하는 바이다.

  • Polycyclic aromatic hydrocarbons (PAMs) are ubiquitous contaminants in marine environments. PAMs enter estuarine and nearshore marine environment via several routes such as combustion of fossil fuels, domestic and industrial effluents and oil spills. PAHs have been the focus of numerous studies in the world because they are potentially carcinogenic, mutagenic, and teratogenic to aquatic organisms and humans from consuming contaminated food. However, one can hardly find any available data on PAM content in marine organisms in Korea. The present study was carried out in order to determine PAM content in oysters from the intertidal and subtidal zones of Chinhae Bay, which is located in near urban communities and an industrial complex, and the bay is considered to be a major repositories of PAHs. 16 PAHs were analyzed by High Performance Liquid Chromatography (HPLC) with uv/vis and fluorescence detectors in oysters: they are naphthalene (NPTHL), acenaphthylene (ANCPL), acenaphthylene (ACNPN), fluorene (FLURN), phenanthrene (PHEN), anthracene (ANTHR), fluoranthene (FLRTH), pyrene (PYR), benzo(a)anthracene (BaA), chrysene (CHRY), benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF), benzo(a)pyrene (BaP), dibenz(a,h)anthracene(DahA), benzo(g,h,i)peryne (BghiP) and indeno(1,2,3,-cd)pyrene (I123cdP). The PAM contents in oysters from the intertidal and subtidal zones of Chinhae Bay ranged from < 0.1 to 992.0 ug/kg (mean $69.8\pm9.8$ ug/kg).

  • The purpose of this study is to provide the planning factors of housing for the disabled and elderly based on the inclusive housing design as sustainable neighborhood. The goal of inclusive design is to make buildings and communities more livable for all type of people. Inclusive design should embrace other good design goals and reinforce them, not work against them. To carry out this purpose, we should proceed in the following way: First, we deducted the four design factors (the basic, recommendable, adaptable, and residential factors) by reviewing the characteristics of inclusive housing concepts. Second, we analyzed the related foreign design standards and guidelines such as the ICC/ANSI A117.1 Type C Units (the United States, 2009), Lifetime Standard (the United Kingdom, 2010), and Livable Housing Design Guideline (the Australian, 2010) through four design factors based on inclusive design concepts. Finally, we suggested the housing design factors for the disabled and the elderly in Korea. To conclude, we can make the followings: It is important basic factor that the bedroom and bathroom layout closed to each other. Also, the bedroom has the proper height of light switches, outlets, and windows. The recommendable factors take into consideration stairs and ramp, if existent. The adaptable factors are closely related to domestic housing culture as well as residential factors. Proceeding from this fact, the livability for people with disabilities and older requires accessibility and adaptability that take into account public and efficiency considering the current trend of housing development and urban planning.

  • The diesel-degrading activities of biofilms sampled from petroleum-contaminated groundwaters in urban subway drainage systems were examined in liquid cultures, and the microbial populations of the biofilms were characterized by denaturing gel gradient electrophoresis (DGGE) and 16S rDNA sequence analysis. Biofilm samples derived from two sites (19 K and 20 K) at subway Station N and Station I could degrade around $80\%$ of applied diesel within 20 and 40 days, respectively, at $15^{\circ}C$, and these results were strongly correlated with the growth patterns of the biofilms. The closest phylogenetic neighbor of a dominant component in the 19 K biofilm was Thiothrix fructosivorans strain Q ($100\%$ similarity). Four dominant strains in the 20 K biofilm were closely related to Thiothrix fructosivorans strain Q ($100\%$ similarity), Thiothrix sp. CC-5 ($100\%$ similarity), Sphaerotilus sp. IF14 ($99\%$ similarity), and Cytophaga-Flexibacter-Bacterioides (CFB) group bacterium RW262 ($98\%$ similarity). Three dominant members in the Station I biofilms were very similar to uncultured Cytophagales clone CRE-PA82 ($91\%$ similarity), Pseudomonas sp. WDL5 ($97\%$ similarity), and uncultured CFB group bacterium LCK-64 ($94\%$ similarity). The microbial components of the biofilms differed depending on the sampling site. This is the first report on the isolation of clones highly similar to Thiothrix fructosivorans and Thiothrix sp. from biofilms in petroleum-polluted groundwaters, and the first evidence that these organisms may play major roles in petroleum degradation and/or biofilm-development.

  • The ecological background of a restoration project is complex and difficult to betermine without experimentation. A useful context for experiments is the well-studied process of natural succession, because the factors that drive or inhibit succession are also at work during reclamation (a form of primary succession) and restoration (which often resembles secondary succession). Using experimental studies on urban wasteland reclamation, we have tested for factors that stimulate or inhibit succession during early phases of woodland development in the Northeastern United states. The emphasis has been on mutualisms (seed dispersal, pollination, and mycorrhizae) and microsite limitations in the recruitment, growth, and reproduction of woody plants. Using plantings of seeds, seedlings, and clusters of reproductively mature plants on abandoned landfills, we have observed that (1) soil microsite deficiencies lead to very poor germination (<0.1$\%$) and seedling survival (<0.01$\%$) of most native species; (2) seed dispersal by birds is a significant and reliable source of woody plant recruitment; however (3) proximity effects are strong, with most (up to 95$\%$) of seed rain falling in the vicinity of planted clusters that are closest to putative seed sources; and (4) remnant natural woodlands are critical components of the recruitment process. To emphasize the last point, in one case, we found that the destruction of approximately 50$\%$ of nearby natural woodland vegetation led to a commensurate decline in seed rain. In another case, we found that the species richness of recruits was strictly limited by the species composition of nearby source plant communities, with no evidence of community enrichment by long distance dispersal over 5 years. We conclude from these results that the size and proximity of remnant natural populations are critical considerations when planning reclamation and restoration programs that rely on natural successional processes.

  • The purpose of this study is to analyze the arrangement of parks, in whole city level by using park's effective distance and to find the accessibility obstacles in case of using parks, in boundary of each parks' effective distance, so that to show how to improve communities' usage of city parks. The 8 cities in Gyeonggi-do and analysed the effective distance of parks. To find the accessibility obstacles in the boundary of parks' effective distance, 1) we choose 18 sample parks and extract obstacles - wide road, rail road, river- in interior and verify it by field survey and asking the park user's residents directly. The main findings of this study can be summarized as follows: First, Ansan city and Goyang city are only satisfied with the minimal city parks size standard, so that the rest 6 cities are lack of quantities which residents can use. The result of analyzing effective distance in whole city level, parks are mainly designated in new-town, so that most cities which have old-towns have very poor park systems to use. Because Ansan city is new-planned city, it is very effective arrangement in park systems exceptionally. Second, $96.2\%$ of park users' are living in the area which was easy to gain access not intercepted by wide road, rail road or river. Third, therefore at the stage of planning park, effective distance and resident's accessibility as well as park's supply quantitatively are needed to be considered. In addition, selection of location and elevation of resident's safety and accessibility through making a plan must be reflected. In the low accessibility area, the program to improve park's accessibility and amenity - like making small park or pocket park, linking parks with resident-friendly road etc.- has to be investigated.

  • The Seonjeong royal tomb is one of many historic sites in and around Seoul city and its natural environment and landscape have born damaged seriously by heavy use. So conservation planning with an estimation of reasonable carrying capacity shall be required In aspect of not only historic site conservation, but also urban forest and nature park management. Eight sites were sampled with clumped sampling method during July of 1986 and five quadrats were examined in each site. Environmental factors, actual vegetation, and environmental impact grade were investigated in field and vegetational structure was analyzed by estimation of importance value, species diversity, similarity index, DBH class distribution, etc. The result of this study can be summarized as follows. 1. Damage on soil and vegetation of middle and lower layer increased according to amount of users'impact. 2. Semi - natural vegetation covered 63% of the total area(22.2 ha) and its major species were Pinus densiflora, Quercus aliena, Q mongolica, Sorbus alnifolia, etc. Pinus densiflora was a dominant species in heavy impact area. 3. Environmental impact grade 3, 4 and 5 area covered 51% of the seminatural vegetation, Especially, the area of impact grade 4 and 5 should be restored because self-refair seemed to be impossible. 4. The semi-natural vegetation was classified with four plant communities; two P.densiflora comm., Q. mongolica-P. densiflora comm. and Q. aliena comm. One of the P. densifolra comm. was destroyed seriously with no younger trees in middle and lower layer by overuse impact and would be bareland soon. But Q. aliena comm.in light impact area showed just completion of plant succession from P. densiflora comm.

  • 물리적 또는 기능적으로 연결된 두 지점에서 발생하는 이벤트(쌍대위치 이벤트)들 사이의 국지적인 공간적 연관성을 평가하는 것은 쉽지 않다. 그것은 대개 그러한 형태의 지리적 현상들이 가지고 있는 프로세스 자체의 복잡한 특성 때문이지만, 실제 공간 상에서 재현될 때 매우 복잡하게 얽혀 시각적 패턴을 인식하기 어렵기 때문이기도 하다. 이 논문은 국지적 스케일에서 공간적으로 자기상관된 쌍대위치 이벤트(또는 벡터)들을 확인하기 위한 대안적 방법을 다루고 있다. 제시된 통계적 알고리즘은 (벡터들의) 시작 포인트들의 클러스터링을 평가하기 위한 단변량 포인트 패턴 분석과 시작 포인트들에 상응하는 벡터들의 유사성 측정을 혼합하여 개발되었다. 사례 분석은 미국 오하이오주 프랭클린 카운티의 지역 주택시장에서 2004년에서 2006년 동안 이루어진 주택거래 데이터를 사용하여 이루어졌다. 분석 결과, 국지적으로 특성화될 수 있는, 특히 지역 커뮤니티와 연관된 다양한 이동들을 보여주는 주택거래들을 확인할 수 있었다.

  • The purpose of this study is to investigate how the hollowization in rural villages which causes marginal villages appears in Korean rural villages and whether the hollowization has relation with decrease and aging of population or not. For achieving the research objective, survey was carried out focused on Geumsan-gun. As a result, it confirmed that rural out-migration and rural decline especially in 'people', 'land(economic situation)' and 'community' have being progressed. Also variance analysis and regression analysis were executed with using the number of population and the ratio of people over 65 as dependent variables and using each survey contents(variables) as independent variables. The results of analysis showed that the ratio of people over 65(+), the income level per household(-), the rate of fallow lands(+), the number of empty houses(+), programs for urban-rural interchange(+), and the implementing public projects(+), etc. have a relation with the number of population(-) and the number of population(-), the income level per household(-), the rate of fallow lands(+), the number of empty houses(+), activities of communities(+), and the implementing public projects(+), etc. have a relation with the ratio of people over 65(+) (+: increase, -: decrease). So the hollowization in people', 'land(economic situation)' and 'community' has direct relation with decrease and aging of population in rural areas.
