  • 이 연구는 1960년부터 2009년까지의 시계열횡단연구(cross-sectional time series) 자료를 이용하여 동남아시아의 각국의 자연자원에 대한 의존도와 정치체제 사이의 상관관계를 밝히고자 하였다. 동남아시아는 중동과 서부사하라 아프리카와 더불어 전 세계에서 가장 자연자원이 풍부한 지역 가운데 하나이나, 관련된 연구는 자료의 부족으로 인해 타 지역에 비해 그다지 축적되어 있지 못한 상태이며, 그나마 단일 사례 혹은 국가에 치중되어 있다. 따라서 본 연구는 기존 자연자원의존도와 정치체제와의 경험적 연구들에서 주장된 인과 관계들이 동남아시아에서도 적용될 수 있는지 살펴보고자 하였다. 분석 결과, 본 연구는 동남아시아에서도 한 국가의 자연자원에 대한 의존도의 증가가 민주주의 발전에 부정적인 영향을 끼친다는 것을 발견할 수 있었다. 구체적으로 본 연구에서 자연자원 의존도로 사용하였던 두 가지 지표인 총 수출 대비 자연자원 수출비율과 국민 총생산 대비 자연자원 수입비율 모두 민주주의 수준을 종속변수로 상정한 각 모델에서 음의 상관계수를 보여주었다. 기존 연구들에서 다루어졌던 주요 이론들인 지대추구(rent-seeking), 지대국가(rentier state), 근대화(modernization)이론을 대표하는 통제변수들을 사용한 대부분의 결과 역시 기존 문헌의 주장을 뒷받침 하고 있다. 그러나 내전 발발과 이슬람을 비롯한 일부 통제변수들의 경우에는 기존 민주화 관련 연구결과와는 상반된 결과를 나타내기도 하였다. 이러한 동남아시아의 지역적 특수성을 보여주는 결과는 후속 연구에 의미있는 시사점을 제시해 줄 것이다.

  • 도시의 일상생활에서는 시가지의 바람이 나무, 집 등 낮은 건축물 군에 의해 방해되어 보통은 전원의 바람보다 풍속이 저감되는 경우가 많다. 이러한 기존의 바람 흐름이 있는 곳에 건축물이 세워지게 되면 기존의 풍환경은 크게 변화되어 풍속이 약한 곳과 강한 곳이 조성되어 이와 같은 바람이 지표부근의 구조물에 의해 받는 영향은 도시지역에서 강하게 나타나게 된다. 이는 교외나 시골지역은 상대적으로 도시지역에 비해 영향을 적게 받게 된다. 임의의 지역, 특히 도시지역의 경우 기존의 건물이 증축되거나 혹은 새로운 건물이 신축되면 이로 인하여 기존의 바람흐름이 달라지며 이는 인접건물들의 확보하고 있던 자연 환기력의 변화를 야기 시키는 원인이 되기도 한다. 이러한 현상은 건축물에 의해 자연 환기력이 바뀌게 되는 일종의 기존 환경으로 부터의 변화를 의미한다. 본 연구에서는 수치해석을 이용하여 이와 같이 건물의 주변 환경변화, 즉 신축, 증축 등과 같은 변화를 고려하여 그 영향을 예측/분석하였다. 그 결과로 건물의 자연환기력을 전면에서 바람에 의한 압력증가와 후면에서 바람의 흡입에 의한 압력감소로 인해 전면의 풍속에 의해 발생하는 동압보다 큰 압력차가 발생하고, 그로 인해 환기량이 발생하는 것을 알수 있다. 주변 변화에 의해서는 동일한 규모의 건물이 추가되는 경우에 기존의 경우에 비해 35~45%의 자연환기격이 감소되는 것으로 나타났다.

  • The regional division by the characteristics of the drainage patterns is important to understand its physical environment comprehensively, because the drainage network develops in reflecting characteristics of geological, geographical and climatical features in the drainage basin keenly. This study is the attempt to divide physical region in China whose drainage pattern is diverse. Chinese drainage basin is mainly divided into the interior drainage basin and the peripheral drainage basin. The interior drainage basin is divided into (1)the deranged pattern and (2)the centripetal pattern. The peripheral drainage basin is divided into (1)the dendritic pattern, (2)the parallel pattern, (3)the radial pattern and (4)the anastomatic pattern. Drainage patterns of the interior drainage basin are formed by affecting geographical features and climatic conditions mainly. In the peripheral drainage basin, drainage patterns are formed by other factors: the parallel pattern is connected with geological structure lineament by tectonic movement, the radial pattern with changes of the river channel resulted from the Yellow River's overflow, the anastomotic pattern with human's activities. The distributional features of the physical region in China are as follows: The deranged pattern appears in Zangbai Plateau, the centripetal pattern does in arid basin of the northwest China. the parallel pattern does in Hengduan mountains affected strongly by tectonic movement between Yangtze paraplatform and Indian Plate, does in the upper stream of Yangtze River and Ganges River in the south of Qinghai-Xizang Plateau, the radial pattern in Huaihe Haihe River drainage basin appearing in the alluvial fan region of Yellow River's downstream and the anastomotic pattern does in the delta of Yangtze River, in the northern coastal plain of the Jiangsu-Province and in the delta of Zhujiang River. Except these areas in the peripheral drainage basin, the dendritic pattern is usually found in the other areas.

  • The remediation of contamiated sites using currently available remediation technologies requires long term treatment and huge costs, and it is uncertain to achieve the remediation goal to drop contamination level to either back-ground or health-based standards by using such technologies. Intrinsic remediation technology is the remediation technology that relies on the mechanisms of natural attenuation for the containment and elimination of contaminants in subsurface environments. Initial costs for the intrinsic remediation may be higher than conventional treatment technologies because the most comprehensive site assessment for intrinsic remediation is required. Total remediation cost, however may be the lowest among the presently employed technologies. The applicability of intrinsic remediation in the contaminated sites should be theroughly investigated to achieve the remedial goal of the technology. This paper provides the frame of the extended site assessment procedure based on knowledge of biodegradability to evaluate the applicability of intrinsic remediation. This site assessment procedure is composed of 5 steps such as preliminary site screening, assessment of the current knowledge of biodegradability, selecting the appropriate approach, analyzing the contaminant fate and transport and planning the monitoring schedule. In the step 1, followings are to be decided 1) whether to go on the the detailed assessment or not based on the rules of thumb concerning the biodegradability of organic compounds, 2) which protocol document is selected to follow for detailed site assessment according to the site characteristics, contaminants and the relative distance between the contamination and potential receptors. In the step 2, the database for biodegradability are searched and evaluated. In the step 3, the appropriate biodegradability pathways for the contaminated site is selected. In the step 4, the fate and transport of the contaminants at the site are analyzed through modeling. In the step 5, the monitoring schedule is planned according to the result of the modeling. Through this procedure, users may able to have the rational and systematic informations for the application of intrinsic remediation. Also the collected data and informations can be used as the basic to re-select the other remediation technology if it reaches a conclusion not to applicate intrinsic remediation technology at the site from the site assessment procedure.

  • This study is to discuss the problems due to the maldevelopment occurred at the reserved areas of natural environments of the Ulleung Island, Gyeongsangbuk-do province, and it also suggests the ways of solving them The types of the maldevelopment practiced on the Ulleung Island consist of the change of land use, the opening of a round road, the destruction of mountains for the construction of harbor, the development of tourist areas, and the construction of military facilities. The decreased habitat of animals and the pollution of drinking water are occurred by the change of land use. The destruction of ecological system is due to the opening of a round road. The damage of natural landscape and the change of ocean eco-system is closely related to the construction of harbor and the destruction of mountains. Finally, the damage of rare plants and the pollution of drinking water are due to the development of tourist areas and the construction of military facilities. In the followings, the ways of solving the problems occurred by the various types of maldevelopment are suggested. First, the planning of pro-environmental development has to be established and practiced to preserve rare plants which are damaged due to the change of land use. Second, the destruction of natural landscape and resources has to be minimized by the implementation of environmental impact assesment when road and harbor are constructed. Third, the stones needed for the development of islands ought to be imported from mainland. Fourth, the established tourist areas are needed to rationally manage and the potential tourist areas has to be transferred to the reserved areas of natural environments. Fifth, military facilities should be constructed though the cooperation of autonomous local government. Finally, government officers' and residents' conscience of protecting and reserving natural environments is needed, and government has to give residents financial supports.

  • 지역이나 국가에 따라 사람들의 색채감성에는 조금씩 차이가 있다. 색채감성에 영향을 미치는 자연환경의 요소로는 생태조건, 기후조건, 자연광조건 등으로 나뉘며, 자연광조건은 자연광의 세기와 색온도, 생태조건은 토양과 식생, 기후조건은 온도와 습도, 쾌청지수 등으로 나눌 수 있다. 이들은 인간이 지각하는 색의 색상·명도·채도와 관련을 갖고 있다. 각 지역의 풍토조건의 차이로 생기는 색채감성의 구조를 자연광의 세기에 따른 명도 변화, 대기중의 습도에 따른 채도변화, 온도차에 따른 색상변화로 나누어 파악하였다. 또한 한국과 일본을 사례로 풍토색과 도시환경색채를 통해 색채감성의 차이를 비교하여 분석하고 그 주원인을 파악하여 지역별 색채 감성을 분석하는 기틀을 마련하고자 한다.

  • This study is a survey on the general perceptions of the residents and visitors regarding the Nature Restoration Period in Chilsun Valley in Jirisan National park, and it was designed to establish systematic park management plan for the Special Protected Areas in Korean National Parks. This survey was conducted on the residents of five towns including Chuseong-ri, Gwangjum-dong, Uijung-ri, Uitan-ri and Uipyeong-ri, as well as visitors to Chilsun Valley by using convenience sampling. The result showed that those individuals or groups who responded to the survey were all positive about preservatory effect of Nature Restoration Period in the valley; however they also showed major perceptional differences as to the ways in which the nature restoration period managed. They also disagreed among themselves on the assessment of the extent of damage that could be generated due to the restoration, the appropriateness of the Nature Restoration Period as a management policy and maintenance of the policy in the future. The appropriateness as a policy and the extent of damage due to the Nature Restoration Period particularly showed some serious perceptional differences among five resident groups based on the location of their towns. To minimize current conflict and achieve the goal of Nature Restoration Period, the park management authorities need to communicate more actively with the stakeholders of the local community and NGOs, and secure their support and cooperation by accommodating their ideas and opinions to build a strategic partnership.

  • We collected the samples of stream sediments from primary channels in order to establish natural background of major and minor elements for geologic units in the Gurye area. Stream sediments samples having no possibility of contamination effect and representing drainage basins composed of uniform geology, were collected from April to May in 1999, the chemical analysis of which was carried out. The tolerable level was used to investigate the enrichment degree of harmful elements. The contents of Ni and Cr exceeded the tolerance level in some sections. The tolerance level excess of those elements was regarded as the effect of the metamorphic rock which constituted the bed rock of the area. In order to identify the comprehensive enrichment pattern, the tolerable level was used in calculating the enrichment index. The enrichment index of harmful heavy metals showed that Granite gneiss area is 0.39, Porphyroblastic granite gneiss area 0.32, Biotite gneiss area 0.42, Migmatitic gneiss area 0.41, Tuff area 0.30, Andesite area 0.46, Conglomerate area 0.42, and Granite area 0.26. Those results showed that natural background of Gurye area had not been exposed to harmful heavy metal elements.
