Annual total values and thereby assets values of natural resources are determined by sample household WTP estimates and the extent of market. In the current domestic practice of CVM, total numbers of national households were used as the target population to measure total economic values including non-use values. This study proposed an alternative method of calculating potential user groups based on distributions of residential area of visitors in the sample using 4 provincial parks in the Chon Buk area as cases. The sample mean of WTP of Moak Mt. visitors, who are mostly from the nearby Chon Buk provincial area, was estimated to be about 8,215 won. On the other hand, the mean of WTP of Sun Woon Mt., whose visitors are evenly distributed from all over the country, was about 4,693 won. When applied national households as the target population, annual total benefits and thereby asset values of Moak Mt. was high enough to be 86 billion and 1.6 trillion won respectively. However, those of Sun Woon Mt. was low to be 52 billion and 1 trillion. On the contrary, when applied potential user groups of each park as the extent of market, annual total benefits and asset values of Sun Woon Mt. was reversed to be high--23 billion won and 400 billion won respectively. However, those of Moak Mt. was lowered to be 10 billion won and 200 billion won. Furthermore, asset values of the same park were differed by 2 to 8 times according to the way of setting the extent of market.

This study estimates the willingness-to-pay (WTP) for avoiding the destruction of a first-grade ecological area by means of contingent valuation method. Specifically, we employ the dichotomous choice technique along with the follow-up questionnaires. Our analysis implies the yearly WTP per household for avoiding the destruction of the ecological area of 100,000 pyongs is 8,898 won with the 95% confidence interval of 6,611~11,976 won. We estimate the asset value of that area to be 1,707 billion won with the 95% confidence interval of 1,269 to 2,298 billion won. We also decompose the total value of the area into the value of direct (22%) and indirect (38.8%) use, the option value (19.9%) and the conservation value (21.3%). Although using these data for SEEA (the system of integrated environmental economic accounting) is bound by certain restrictions, one could employ our empirical findings as advisory information for decision making in the process of prior environmental review or for assessing the environmental impact.

Iksan is one of medium city in Jellabukdo, South Korea. It has a favorable natural environment for the specialization potential of natural industries and development projects. In addition, it has various historical and cultural resources including Mireuksajji, and KTX Honam line which has been opened for a representative feature as transport city. However, it faces week connection with neighboring cities and large scale of development in neighboring areas, especially in Jeonju and Gunsan. In this paper, we try to classify the urban image assets of Iksan as 'Iksan Station' and 'ktx' on keywords and analyze the possibility of being a center of transportation and logistics through big data analysis extracted from SNS and website. In comparison with Gwangju Songjeong, KTX Honam line station, which has been developed with similar regional characteristics, it is aimed to establish the basis of improvement and establishment of urban image of Iksan city in the future.

Most local governments make an attempt to attract tourists through the large-scale development projects or regional festival events. But, its possibility of success is actually low, so they must take care of ecotourism industry which has higher efficiency in comparison with investing expense. Seocheon area couldn't be focused greatly in spite of the excellent ecological and cultural resources. However, there are lots of possibilities to be a new center of ecotourism because of newly opened National Institute of Ecology and National Marine Biology Resource Institute. Therefore, the purposes of this thesis are to analyze several eco-cultural property all over Seocheon, introduce ecotourism, a main function of ecosystem services, and develop the program satisfying 3 elements of ecotourism; natural environment, visitors and residents. In Seocheon located in where the sea meets the river, ecological property could be reorganized into 4 areas in relation to existing famous tourist attractions. As a measure to let visitors stay, we induced them to lodge in the region through the field work. To realize slow life, we designed it so that they can enjoy each landscape slowly. we also suggested the program which can guide visitors onto the vicinity of habitat for migratory birds at the mouth of Geumgang River and Seocheon foreshore nominated as Ramsar wetlands by focusing on National Institute of Ecology and National Marine Biology Resource Institute which will be the Mecca of ecology research. Through this research, there will be an opportunity to satisfy visitors of Seocheon and enrich local residents' lives.

Native plants thrive naturally in specific areas without human intervention, offering significant potential as genetic resources and biotechnological assets across multiple sectors. To harness this potential, our focus was on analyzing domestic patents related to native plants, investigating their uses, effectiveness, active components, and extraction methods. Using the Korea Forest Service's National Standard Plant List, we gathered data from 988 patents on native plants and 430 patents on the use of native plant seeds. This comprehensive patent analysis aimed to reveal research patterns, technology levels, and emerging trends. The goal is to identify research trends, current technology levels, and provide insights for future patent applications involving native plants.

Recently mountain tourism has been promoted and introduction of railroads with utilizing mountain resources is being planned. With the government policies to increase the share of eco-friendly transportation on railroad, national double-tracking of single rail and improvement projects are on going. However, the eco-friendly railroad policy suggests the environmental impact assessment items only on air quality, water quality, geographical/geological features, fauna/flora, natural/environmental resources, noise/ vibration, and recreation/landscape. And for fauna/flora and natural/environmental resources, confirming the presence of environmental protection zone is enough to satisfy legal requirement. This study suggested to evaluate environmental/ecological values with quantitative data. Evaluation indices and evaluation items have been selected to provide the data. Each of the subject map and railroad network was overlapped. The study selected naturalness and diversity as major indicators and calculated weight values of the items under the indicators, which are to be usd for the selection of the sites for railway development. This assessment method could be applied to the environmentally friendly construction of railroads in the future.

The role of local decentralization and balanced regional development becomes important due to the concentration of population due to urbanization, and the development of tourism contents in local governments is actively being attempted. However, this is largely due to quantitative growth, and it does not offer tourist content that offers a different experience while utilizing regional characteristics. This means that it is important to develop programs and contents that emphasize the identity of the region by cultivating local characteristics and build a different image. However, most of the small regions where characteristic resources are difficult to find have a problem that it is difficult to develop different programs and contents due to relatively few development opportunities and financial constraints. In this study, it was considered that it is effective to analyze characteristic features of the region and utilize the possessed assets as much as possible. Therefore, we propose a service design process that effectively supports ecotourism, one of the regional revitalization plan using local eco - assets. In the process, Venn Diagram Position and Context Map methodology was developed and verified through Sutonggol Observation Path.

To detail a picture of the economic value of Miscanthus landscape conservation in terms of cultural services aspects of Ecosystem Services, Sunghaksan(Mt.), Hwawangsan(Mt.) and Jaeyaksan(Mt.), which are known for their Miscanthus colonies, were chosen as survey sites. After examining the willingness to pay for the value of Miscanthus landscape conservation by targeting of visitors each study area, the economic value of Miscanthus landscape conservation per capita aspects was evaluated using Contingent Valuation Methods(CVM) from the collected willingness to pay for economic value of Miscanthus scenery by site. After using the target Chi-square test to analyze the differences among each site, the correlation between specific variables was investigated. Willingness to pay for the Miscanthus landscape conservation was found to increase as the respondents' income became higher. The more environmental conservation efforts were being made in their daily life, the higher willingness to pay was for Miscanthus landscape conservation. Likewise in other studies, the higher the bid was, the less willingness to pay was. The per capita assessment of the Miscanthus landscape value of the logit models in the dual estimated using the factor extracted with each of the injected variable bounds was estimated for Seunghaksan (\38,277), Hwawangsan(\38,648), and Jaeyaksan(\48,891). The average of the three sites was estimated to be \38,679. Assessment of the economic value of these Miscanthus landscape sites saw high willingness to pay by visitors when compared to the current market price inflation, such as watching movies or amusement park admission, which could mean that visitors recognize the value of ecosystem services from nature in evaluating the Miscanthus landscape.

최근 해안송림에 대한 관심이 높아지고 있고, 이를 효과적으로 보전, 활용해야한다는 목소리가 높지만, 국내에서는 이러한 해안송림이 어떻게 변천되고 지역에 어떻게 기능해 왔는지 아직 알려지고 있지 않다. 본고는 해안송림의 기초연구로서, 하동송림을 대상으로 이러한 해안송림의 사회적인 기능과 관리문제를 검토한 것에 있다. 하동송림을 사례로 조사한 결과, 해안송림은 송림이 지역과 밀착함으로써 주민의 레크레이션기능은 물론 외부관광객을 끌어들일 수 있는 지역발전의 중요한 소재가 될 수 있는 것으로 나타났다. 또한 해안 송림이 지역주민의 일상생활과 밀접히 연관되고 지역발전의 한 축으로서 기능하면서, 송림에 대한 관리 및 주체의식이 높아지는 것으로 나타났다. 이러한 지역발전의 실질적 기능 및 자연스러운 관리의식의 고양은 일반 공원이나 원거리 해안림 등에서는 쉽게 나타나지 않는 것으로서, 마을 숲(해안송림 등)이 갖고 있는 하나의 중요한 잠재력이 아닌가 생각된다. 그러나 관리측면에서는 하천오염이 해결되지 않고, 송림확장계획이 중지되고, 소나무재선충 방지책에 의문에 제기되는 등 적지 않은 문제가 나타나고 있다. 또한 이러한 문제발생의 원인으로는 해안송림에 대한 기본적인 인식의 부족, 책임 있는 관리주체의 부재, 구체적인 연구의 부족 등이 검토된다. 해안송림의 기능과 식생은 고정되어 있는 것이 아니라 지역 환경에 따라 끊임없이 변화되는 것에 있어, 변화에 대응하는 개발논리가 필요하다. 따라서 이러한 특수성을 일반적 임업관리나, 시설보수 차원에서의 접근은 소중한 지역의 자산과 발전기회를 잃은 거와 다르지 않다. 소중한 지역자원의 가치를 빛내고, 보다 효과적인 활용을 위해서는, 보다 체계적이고 파지티브한 관리 및 활용 정책이 요구되는 것에 있고, 이를 위해서는 책임 있는 관리주체를 조직하는 것과 함께, 토지사병에 기초한 송림의 이용 및 식생 변화에 대한 연구가 필요한 것으로 판단된다.

In Korea, an olive flounder is very popular fish food item. However, due to the increasing human population, the present catches of the olive flounder may not be sufficient to satisfy the present demand. To increase the supply of the olive flounder, aquaculture has been begun. An interest in the aquaculture of the olive flounder has been increased recently because of its characteristics of good growth and high price in the market, However, the productivity of the olive flounder aquaculture depends on economic inputs such as fuels, facilities, and labor. The rapid growths of the olive flounder aquaculture and the concerns about economic and ecological sustainability have focused peoples attention on the aquaculture industry. In this study, an energy systems model was built to simulate the variation of sustainability on the aquaculture of olive flounder, The results of simulation based on calibration data in 1995 show that olive flounder production yield and asset slowly increase to steady state because of the law of supply and demand. The results of simulation based on the variation of oil price show that the more increase the oil price, the more decrease the olive flounder economic yield and asset. Energy sources required for systems determine the sustainability of systems. Conclusionally, the present systems of the olive flounder aquaculture should be transformed to ecological-recycling systems or ecological engineering systems which depend on renewable resources rather than aquaculture systems which depend on fossil fuels, and be harmonized with the fishing fisheries by the sustainable use of renewable resources in the carrying capacity.
