백두대간은 한반도의 근간 축을 이루며 한민족의 상징성을 지닌 지역으로 총 연장 약 1,600km. 해발 100m부터 2,750m로 1대간, 1정간, 13정맥으로 이루어져 있으며 백두대간은 산자분수령의 기본 개념에 따라 우리 땅의 골간을 이루는 한반도의 중심 산줄기이다. 또한 남과 북이 하나의 대간으로 형성되어 있다는 상징적인 지리인식체계에 바탕을 두고 있다. 백두대간의 생태계는 우리나라 생물 다양성을 대표하는 자연환경 지역으로서 자원보전적 가치와 함께 입지 및 자원특성에 기인한 다양한 자원이용 환경도 존재한다. (중략)

The purpose of this study was to investigate the effects of human, social and cultural capital and ecological variables on volunteering among older adults. In this study, three variables of education, income and physical health were examined as human capital factors, two variables of formal and informal interaction as social capital factors, three variables of religion, cultural organization participation and quality of life as cultural capital factors, and three variables of existence of spouse, housing tenure and residence area as ecological factors. In addition, two variables of volunteering participation and continuous volunteering participation intention were considered as dependent variables. For this study, "Senior Job Replacement Project Participants" data collected by the Korea Labor Force Development Institute for the Aged were used and analyzed employing logistic regression analysis technique. This study found that three human capital variables(education, income, physical health) had positive effects on volunteering participation and continuous participation intention among older adults; of the two social capital variables, informal interaction had a positive effect on both volunteering participation and continuous participation intention, whereas formal interaction had a positive effect only on continuous participation intention; three cultural capital variables(religion, cultural organization participation, quality of life) had positive effects on both volunteering participation and continuous participation intention; and of three ecological variables, housing tenure and residence area had positive effects on volunteering participation and continuous participation intention, whereas existence of spouse had no significant effects on dependent variables.

As recent interest in ecological resources increases, an effort in three-dimensional visualization of the ecological resources has increased for the restoration and preservation of the natural environment as well as the evaluation of the landscape. However, in the case of forest resources, information extraction has been active, but the effort in trying to apply that information into an effective visualization has not happened. In other words, the effort for effective visualization is lacking when it comes to the visualization of forest resources, and numerous cases are ether non-realistic or the simulation required for analysis is inappropriate. Therefore, this paper extracts information through the use of airborne LiDAR data, aerial photograph, and forest type maps to create a vegetation layer, and then uses Flora3D forest modeling tools and ArcGlobe to accurately visualize the vegetation layer into the three dimension. An effective application for restoration and preservation of ecological resources as well as analysis on the urban landscape can be considered as a result of intuitively and realistically enabling the user's awareness of forest information within the Geographic Information System.

The Korean Demilitarized Zone (DMZ) has the great ecosystem as all the artificial activities in DMZ have been prohibited over half a century. The ecosystem should be conserved even after the reunification of Korea and hence the conservation plan should be established not after the reunification but before it. It requires a considerable budget to conserve DMZ, considering management of ecology resource, recovery, and research. The objective of this paper is to analyze a fund-raising measure for DMZ conservation, using economic incentives mechanism when multiple developers participate in the auction to get the right to develop North Korean regions, have private information about their sunk costs and pay a part of their profits for the fund. First, we analyze the real option model to decide the optimal investment time. Second, we construct the auction for bidders not to misrepresent their private information, based on Bayesian Nash equilibrium.

지역개발과 지역의 지속가능한 발전전략의 수립을 위해 지역의 환경적, 사회적, 경제적 특성을 통합한 지속가능발전 모델을 구축하는 것은 매우 중요하다. 본 논문은 지속가능발전 전략의 모색과 관련정책의 파급효과를 측정하기 위하여 이러한 통합모델의 개발과 적용을 목적으로 한다. 이러한 목적에 따라 높은 환경질을 유지하고 대나무와 같은 생태자원을 육성함으로써 생태관광과 대나무신산업 등의 새로운 지역개발 정책을 수행하는 전라남도 담양군을 대상으로 지속가능발전 체계동태모형을 구축한다. 담양군 사례분석의 결과는 죽림육성 정책과 대나무신산업과 같은 지역특화산업에 대한 기술개발 및 각종 재원의 병행이 인구유입과 지역경제의 활성화에 매우 효과적임을 제시하고 있다. 결론적으로 본 논문에서는 지역의 지속가능성에 관한 시스템적 사고를 통해 지역개발에 있어서 지역의 환경적 특성을 살린 생태자원의 육성과 적절한 산업정책을 병행하는 생태발전 전략이 지역의 지속가능발전에 있어서 매우 중요한 수단이 될 수 있음을 제시하고 있다.

현재 세계 해양의 어업자원은 상당부분이 최대 지속적 생산량을 넘는 수준에서 개발 이용되고 있는 상황이며 1980년에서 1990년의 10년 동안 과도 어획된 종의 수는 2.5배가 증가하였다 (Alverson and Larkin 1994). 세계 해양에서 어획되는 대부분의 어획물은 점진적으로 낮은 영양단계에 위치한 종의 상대적 비율이 증가되고 있다 (Pauly et al. 1998). 어획활동은 해양생태계의 구조와 기능의 변화를 초래하지만 어획으로 인한 생태학적 변화는 종종 무시되어 연구의 대상이 되지 않았다. (중략)

An ecological niche is defined as the specific role of a species influenced by time, space, and other resources. By investigating overlaps between ecological niches of different species, we could estimate the degrees of interspecific competition. Such studies often use geographic information systems (GIS) to discover niche overlaps between species. In this study, we used GIS to estimate the spatial niches of two Korean frog species(Pelophylax nigromaculatus and P. chosenicus). This enabled us to predict their geographic distributions in order to identify their coexistence regions and distribution patterns. The results confirmed that altitude was an important variable for predicting their distribution, with a correlation with their climatic range. Spatial distributions of the two frog species were highly overlapped, as the distribution range for P. nigromaculatus included most of the range of P. chosenicus, showing a sympatric distribution pattern. Within the coexisting regions, however, the presence sites for the two species did not overlap, implying weak competition. To confirm the principal factors influencing their competitive relationship and reasons for their sympatric distribution pattern, we need more detailed in-depth studies on the diverse environmental variables within the regions where the two species coexist. By doing so, we would be able to identify various mechanisms for avoiding competition in sympatric frog species.

The Demilitarized Zone (DMZ) of Korea has been crucial not only for its buffering role between two Koreas, but also for the conservation of various resources across its premises. The objectives of this study is threefold. The first objective is to identify major resources that determine economic values of the DMZ and its vicinity. The second and third objectives are respectively to estimate conservation values of those resources using Choice Modeling and to test whether or not respondents living in different geographical locations have significantly different willingness to pay for the conservation. In a very conservative estimation, results showed that Korean adults have about 55,000 Won on average for conserving five major resources : the DMZ area, endangered species, cultural heritage items and sites, the Truce Village, and villages in the Civilian Conroal Zone. This equals the aggregate economic value of about 2,07 trillion Won. Moreover, significant regional differences were found in public benefits from conserving these major resources.

남극 크릴(Antarctic krill, euphausia superba)은 남극해의 생태계 피라미드의 하위부분을 차지하고 있지만 동물플랑크톤과 고래, 어류, 펭귄, 조류 등의 상위 포식자들을 연결하는 중요한 연결고리의 역할을 하고 있다. 많은 생체량과 남극해 전체에 골고루 분포하고 있는 크릴은 생태계 자체의 연구뿐만 아니라 수산자원 연구의 중요한 부분을 차지하고 있으므로 분포 위치, 자원량에 대한 연구가 최근 들어 활발히 진행되고 있다. (중략)
