This study conducted an empirical analysis on a land purchase requisition policy in Bukhansan National Park to draw the efficacy, limitations and implications of this policy. A logistic regression analysis was conducted to identify factors that affected the landowners' decision on applying for land purchase requisition using the government's records on acquisition of private lands in the park since 2006 when this policy began to be implemented. Results illustrate that the probability that a landowner applied for purchase requisition increased if the land was classified as forest, if a large proportion of the land was designated as the nature conservation district, if it was located farther from park boundary, and if it had higher appraised value per square meter. These results indicate that as the landowners had less chance to utilize their lands, they more likely apply for purchase requisition. These results also imply that the government can achieve a high conservation performance level if private lands are acquire by the land acquisition requisition policy. The logistic regression model also predict that 401m² of the private lands in Bukhansan National Park will likely be purchase-requested in future. Despites its usefulness in mitigating landowners' complaints in national parks, the land purchase requisition policy has not been widely utilized. Based on these empirical results, this study provides policy implications to facilitate the ulitization of this policy.

The purpose of this research is to identify satisfaction levels of the arboretum which will be provided in the Multifunctional Administrative City and to estimate the economic value of using choice experiments. The attributes were "Preservation", "Education", "Recreation", "Facility", "Accessibility" and the entrance fee. The main effects model was utilized to construct hypothetical alternatives. Calibration of the conjoint choice model revealed that 'wetlands' and 'forest trails' in "Preservation" and the "Recreation", respectively, were significant variables. This result indicates that respondents are willing to pay more for these if they are provided in the arboretum. Also, 'variety seeking' tendency, age, and income level positively influenced the provision of the arboretum. Involvement in preservation of natural environment, however, had a negative influence on the establishment of the arboretum. Because this study is the first attempt to estimate the economic valuation of an urban arboretum using choice experiment, there are several suggestions for future research in terms of determining the base level and inclusion of salient attribute levels.

While the expansion of protected areas in accordance with Korea's National Biodiversity Strategy contributions to the conservation of biological diversity, it incurs economic losses and poses threats to the livelihoods of local residents. Payment for ecosystem services (PES) compensates local residents for their economic damages in a sustainable manner. To assess feasibility of PES, there is a need to estimate the general public's benefits from biodiversity conservation in protected areas. This study attempted to estimate visitors' willingness to pay (WTP) for biodiversity conservation in Mt. Jiri using the contingent valuation method (CVM). The WTP of respondents for the expansion of protected areas to increase biodiversity conservation was estimated at 16,103 KRW per household per year and this equates to a total of 316.8 billion KRW for all the households in Korea. The higher a respondent's age, education level and household income level, the more willing he or she is to pay for biodiversity conservation. Likewise, respondents who are aware of Mt. Jiri's designation as an Ecosystem and Landscape Conservation Area are more willing to pay for biodiversity conservation. Moreover, the higher the importance placed on biodiversity conservation policy, the higher the willingness to pay for biodiversity conservation. To enhance the feasibility of PES schemes, it is necessary to improve the general public's knowledge and awareness of biodiversity by providing opportunities for education and more information on biodiversity and biodiversity policies.

The aim of the study is to explore how to approach the inherent value of nature, which is the main object of earth science education, beyond its instrumental value, which is its external usefulness. Above all, it is said to be an activity-based inherent value in the entire transfer process of the experiment, which includes psychological elements. At the core of environmental ethics is value and the utilitarian question of what is worth continuing. It is a matter of more than simply continuation. The answer is the sustainable value of the natural environment, an education that must preserve its beauty as an inherent value, that is, as a heritage value as a lover of life. Furthermore, the area of valuation must be upgraded from synchronic to diachronic ethical values, with sustainable values instead of intrinsic values. In environmental ethics, the intrinsic value that shows the beauty of knowledge itself is called bequest value. The study distinguished between a priori intrinsic value that ignores existing experience and intrinsic value that is experience-oriented and activity-oriented. In addition, the intrinsic value principle centered on activities was explored through scientific experiments in earth science education and Eratosthenes's earth size measurement experiment. The value principle according to the scientific worldview serves as the basis for value judgment. Above all, intrinsic value was being revealed through the active value experience of the experiment, in which aesthetic values were involved in the process of inferring the experiment results. As an educational implication, it should be value-education that helps us internally transfer intrinsic values rather than instrumental values, which are the basis for creating a sustainable society and nature.

This study aims to, first, classify the approach system of utilizing national and local amenities into three groups: evaluation of the level of the amenity, evaluation of the value of amenity resources, and utilization of amenity resources. Secondly, the study aims to derive an evaluation index which is required according to the approach system. As for a strategy of utilizing amenities, the self-diagnosis based on the evaluation of the level of local amenities is required. In this study, three sectors, ten items and 43 detailed items have been derived though specialists, FGIs(Focus Group Interview), and the cases within and outside of the country. In the survey with specialists, a unit-space key index which can be used in accordance with the unit-space characteristics(such as urban and rural area, fishing villages, mountain villages, and littoral areas), environmental area, important index and optional index have been derived. As for the evaluation index which is needed for the development of typical local amenities resources, 14 detailed evaluation indexes from three sectors have been derived. These have been classified again into six key indexes, six important indexes and two optional indexes. In the evaluation index of amenity resources, natural and environmental value-such as ecological value of preservation, uniqueness of aesthetic landscape and ecological value of restoration-historic and cultural value of preservation and individuality of the resources, and aesthetic and cultural values are derived as being important. As for utilization of amenity resources, 15 items from three sectors-such as reservation, restoration, intentional use, and industrial use-have been derived. Also, through a survey with specialists, key indexes and important indexes were derived by unit-space. As a result, in urban areas, seven items-including creative development of space, aesthetic landscape control and development of cultural contents-have been derived as key indexes; in rural areas, mountain villages, fishing villages and littoral areas, eight items-including brand of region, brand of the products, and brand of tourism resources-have been derived. In environmental areas, six items-including reservation of natural resources, historic and cultural heritage, and restoration of ecosystem-have been derived. Indexes derived from this study can be utilized in order to establish a strategy for amenity plans and an implementation strategy, but can be readjusted, allowing for various regional characteristics. It is, thus, advisable that local governments selectively utilize indexes according to regional characteristics or newly develop them for the maximum utilization of regional amenities.

The purpose of this study is to estimate the economic value of the Kumjung Mountain, using a Individual Travel Cost Model(ITCM). This paper compares Poisson and negative binomial count data models to measure the tourism demands. Interviewers were instructed to interview only individuals. So the sample was taken in 700. A dependent variable that is defined on the non-negative integers and subject to sampling truncation is the result of a truncated count data process. The results suggest that the truncated negative binomial model is improved overdispersion problem and more preferred than the other models in the study. This study emphasizes in particular 'travel cost' that is not only monetary cost but also including opportunity cost of 'travel time'. According to the truncated negative binomial model, estimates the Consumer Surplus(CS) values per trip of about 60,669 Korean won and the total economic value was estimated to be 252,383 Korean won.

벌개미취(Aster koraiensis Nakai)는 국화과에 속하는 우리나라 자생종으로 어린잎은 식용하고, 항비만 및 고지혈증 예방 등의 연구 결과가 보고되어 이용 가치가 높다고 알려져 있다. 또한 주로 조경소재로 이용되고 있으며, 생태복원을 위한 소재식물로 벌개미취를 이용하려는 시도가 이루어지고 있다. DMZ 남방한계선 철책 주변에는 군의 경계작전을 위해 반복적으로 식생을 제거한 지역(불모지)이 형성되어 있어 이를 복원할 필요가 있다. 생태복원에 있어 가장 기본적인 종 선정 방법은 자생종 또는 인접 지역종을 이용하는 것이다. 벌개미취는 DMZ 일원에 자생할 뿐만 아니라, 건조한 환경은 물론 습윤한 지역에서도 생육한다. 본 연구에서는 토성에 따른 벌개미취의 발아 특성과 광조건에 따른 광합성 반응을 조사하여 DMZ 불모지와 유사한 환경에서의 생육이 건전한지 살펴보고자 하였다. 이를 위해 벌개미취의 기내발아 검정(15℃, 12/12h)과 토성(마사토, 상토, 혼합토)에 따른 종자 발아율을 비교하였고, 차광(0, 50, 75 및 95%)처리에 따른 엽면적당 건중량, 엽록소 함량, 광-광합성 반응을 조사하였다. 벌개미취의 발아율은 기내(79%), 마사토(74%), 상토(82%) 그리고 혼합토(77%)로 나타나 각 처리구간 유의한 차이가 나타나지 않았다. 벌개미취의 엽면적당 건중량은 차광수준이 높을수록 감소하였고, 엽록소 a와 b 함량은 차광수준이 높을수록 감소하였으나 a/b는 통계적으로 차이가 없었다. 광-광합성 반응을 통해 산출한 벌개미취의 광포화점과 광합성 최대속도는 차광수준이 높을수록 감소하는 경향이 나타났고, 순양자수율은 증가하는 경향이 나타났다. 벌개미취는 전천광보다 낮은 광도에서 생장 시 광합성 능력이 감소하는 것으로 보이며, 광이 제한되지 않는 불모지 환경에서 생육이 유리할 것으로 생각한다.
