Ecotourism is widely known to be a sort of alternative tourism which seeks to keep balance between conservation and development. Successful ecotourism is not just dependent upon natural/cultural resources but also the consensus-building and collaboration among actors involved in the development of ecotourist attractions. In this sense, the establishment of good local governance can be crucial to achieve both conservation and development which are incompatible one another. Governance is carried out through self-organising, inter-organisational networks, which is emerging as new forms of collective decision-making at local level. Governance leads to the development of different relationships, not simply between public/ nonpublic agencies but between citizens and public/nonpublic agencies. I represent some key dimensions to construct good local governance in ecotourism: i) the creation of socio-institutional milieu that facilitate interactions among actors related to ecotourism; ii) actors involved in ecotourism taking responsibility to play an appropriate role in their own position. I argue that interactive relationships and consensus-building between different actors can be promoted by collective actions such as the sharing of information and resources, co-education and co-training, and seminars. It therefore implies that local good governance cannot be established without local social capital based on trust and cooperation between actors.

전 세계적으로 기후변화로 인해 슈퍼태풍 및 극한 강우, 폭설과 한파, 온난화 현상이 발생하고 있으며, 한반도의 기후변화는 전 세계 평균보다도 빠르게 진행되고 있다. 특히 북한지역은 오랜 식량난과 에너지난으로 산림생태계가 훼손되어 홍수 및 이수와 같은 기후변화 관련 자연재해에 매우 취약하며, 무분별한 도시화에 따른 불투수층의 증가로 인해 유역내의 수문순환요소가 변화하고 있다. 이러한 기후변화에 효율적으로 대처하기 위해서는 체계적이고 과학적인 기상 및 기후정보의 활용이 중요하다. 하지만 본 논문의 대상지역인 북한지역은 우리가 수문자료를 구하기가 힘들고, 직접 측정 할 수 없기 때문에 수문순환분석에 한계가 있다. 따라서 본 논문에서는 WMO에서 제공하고 있는 북한의 27개 기상관측소의 강수량, 기온자료를 제공 받아 분석에 사용하였다. 본 논문에서는 기상정보를 이용하여 각 관측소별 잠재 증발산량을 산정하였으며, 또한 lumped conceptual model 인 WASMOD 모형을 이용하여 북한 미계측 유역의 유출량을 산정 하였다. 이렇게 산정된 수문순환요소 시계열 자료를 이용하여 통계분석, BCP, 유황분석등 시계열 분석을 통해 북한지역의 수문순환특성을 파악하고자 한다.

최근 연안 해역에서의 표사문제는 사회적인 문제로 관심의 집중이 되고 있다. 특히 자연 환경 변화와 연안 구조물 건설과 같은 인위적 환경변화가 복합적으로 작용하여 연안에서의 침식이 가중되고 있으며 이에 따라 해안표사, 연안 생태환경 및 연안방재에 심각한 상태에 이르고 있다. 따라서 환경적인 측면뿐 아니라 이용자의 측면에서 장기적인 해빈보전 계획의 수립이 불가피한 실정이다. 장기적인 해빈보전계획을 수립하기 위해서는 연안해역 자체의 표사 변동 뿐만 아니라 연안으로 유입되는 표사의 공급원을 파악하는 것이 중요하다. 따라서 하천에서 연안해역으로 공급되는 유사량을 예측하고 유사가 어떻게 연안해역에 표사로 이송되어 가는가를 파악하는 것은 연안표사문제를 이해하는데 중요한 요소라 할 수 있다. 본 연구에서는 강릉 남대천하구역에서 유출되는 하천유사량을 혼합입경의 관점에서 검토하여 도류제 설치에 따른 하구역에서의 지형변동 및 하구폐색현상을 해석하였으며, 하천으로부터 공급되는 유사량을 고려하여 강릉 남대천과 인접한 남항진해수욕장 인근에서의 장기적인 해안선변동 특성을 고찰하였다.

스마트TV의 등장으로 콘텐츠, 서비스 플랫폼, 네트워크, 단말을 포함하는 전 방송 서비스 시장 생태계에 변화가 일고 있다. 스마트 TV는 웹 콘텐츠 수용, 앱과 웹 서비스를 통해 사용자에게 TV에서의 새로운 서비스 경험을 제공한다. 그러나 시장 의존적인 플랫폼과 느슨한 웹 서비스 표준, 클라이언트-서버 구조 기반의 개별적 웹 서비스 구현 방식으로 인해 기존의 표준 기반의 방송 서비스와는 매우 다른 특성을 가진다. 본 고에서는 서비스 환경의 변화를 살펴보고, 스마트 TV 환경에서의 서비스 제어 측면에서의 제약 요인들과 새롭게 요구되는 서비스 제어 기능 요소들을 살펴본다.

Vegetation is the basis for biodiversity conservation and sustainable development. In the Environmental Impact Assessment (EIA), which is the most direct and efficient policy measure to prevent degradation of nature, vegetation-related assessment has limitations as it is not based on quantitative and scientific methods. In addition, it focuses on the presence of protected species; hence, it does not take into account the role of vegetation as a habitat on a wide-area scale. As a way to overcome these limitations, this study aims to contribute to the quantification and advancement of future EIA on vegetation. Through the review of previous studies, core areas, connectivity, and vegetation condition were derived as the items to be dealt within the macroscopic aspect of vegetation impact assessment. Each item was spatially constructed using land cover maps and satellite imageries, and time series change analysis was performed. As a result, it was found that vegetation has been continuously deteriorating due to development in all aspects, and in particular, development adversely affects not only the inside of the project site but also the surrounding area. Although this study suggested the direction for improvement of the EIA in the vegetation sector based on data analysis, a more specific methodology needs to be established in order to apply it to the actual EIA process. By actively utilizing various environmental spatial data, the impact of the development on the natural ecosystem can be minimized.

Recently mobile service industry has grown very rapidly. In this paper, I investigated the changes in mobile service industry as well as new direction of human life in future global society. Under these changing market conditions, competition has been also changed into global and ecological competition. But compared to the platform initiatives and ecological strategies of global companies, Korean companies' vision of building ecosystems is still unclear. New directions of mobile service industry are smart phone oriented open market, UCC, QPS and cloud computing. As such, I investigate the structure of mobile service ecosystem in order to gain strategic implications and insights in this paper.

This study aimed for the scientific approach of Korean traditional house, so called Hanok, by analyses of structural elements and thermal environmental performance. Hanok is a very unique vernacular architectural style of the Middle East Asia that fits with climate conditions of the Korean Peninsular, designed to withstand high temperature and humidity in summer and cold and dry in winter seasons. In order to evaluate thermal environment of Hanok, its sectional structure such as floor, wall, roof structure and Ondol which is Korean traditional floor heating system, was built in 3D, as well as heat transfer mechanism of its composing elements was analyzed through 3 dimensional steady state analysis. The results of the thermal environmental performance of Hanok will be used as a basic datum of design guidelines for accomplishing ecologic housing fitted with local climate.

The estuary is a transition zone where fresh water and salt water meet because the stream is connected to the open sea area. So estuaries have very high biodiversity and form a unique ecosystem. However, before the recognition of the ecological value of the estuaries, various damage and disturbances have been occurred so countermeasures are needed. The river master plan is acting as a disturbance factor. However, the river master plan has the public object such as water disaster defense, river function improvement, and national water resources management. Therefore, it is necessary to study the ways in which the opposite relationship of development and ecosystem protection coexist. In this study, the concept of environmental windows were used to estimate the low impact development duration. We expected that proposed method for low impact development duration estimation can be used as a basis and basic data to protected the ecosystem from development project and disturbance in the future.

Micro climatic conditions within the livestock facility are affected by various factors such as ventilation, cooling, heating, insulation and latent and sensible heat generation from animals. In this study, numerical BES method was used to simulate energy flow inside the poultry house. Based on the BES method and THI concept, degree of thermal stress of poultry was evaluated according to the locations in South Korea. Comparison of THI values within the poultry house was also carried out according to the stocking densities to reflect recent animal-welfare issue. Significant decrease in thermal stress of poultry was observed when the stocking density of $30kg/m^2$ was applied in the change of the seasons(p<0.05) however, there was no statistically significant difference in summer season(p>0.05). It meant that installation of proper cooling system is urgently needed. For Iksan city of Jeollabuk-do province, total 252 hours of profit for thermal stress was found according to decrease in the stocking density.

지속되고 있는 기후변화의 영향으로 발생하는 기상현상들이 사회적 문제로 대두되고 있으며, 기후변화에 따른 국지적 극한 사상에 대한 전망은 수자원 활용 계획을 수립하고 대응하는 데 있어 필수적인 요소로 인식되고 있다. 이에 기후, 수문, 지리, 생태 및 환경 등의 다양한 영역에서 신뢰할 수 있는 공간적 강수량의 요구가 증가하고 있지만 지형의 약 70%가 산악 지형인 우리나라의 경우 기존의 일반적 공간보간 기법인 IDW 및 크리깅 방법은 고도가 높은 지역의 기상인자를 추정하는 데 한계가 있는 것으로 평가 받고 있다. 프리즘(Precipitation-Elevation Regressions on Independent Slopes Model, PRISM) 기법은 지형적 특성을 고려한 격자형태의 기상인자를 생산할 수 있는 유용한 방법으로서 미계측 유역에 대한 신뢰할 수 있는 일 단위 강수량 추정을 위하여 SCE-UA (Shuffled Complex Evolution-University of Arizona) 기법을 활용하여 최적화 하였다. 본 연구결과는 PRISM 기법의 국내 적용 시 정확도 향상에 기여할 것으로 기대된다.
