자연휴양림이 도입된지 20년이 지나는 동안 휴양림마다의 특징성이 부각되어 각각의 휴양림이 가진 개성이 있음에도 불구하고 자연휴양림의 유형에 대한 분류가 거의 없는 실정이다. 본 연구는 자연휴양림의 공급적 측면과 이용적 측면을 고려한 유형분류를 실시하여 유형에 따른 효율적인 자연휴양림 운영관리 또는 자연휴양림에 관한 연구 시 연구지 선정의 기초 자료로서의 제공에 그 목적이 있다. 자연휴양림 유형분류를 위한 방법으로는 자연휴양림 유형분류를 위한 최적의 변수로 생각되는 항목들을 선정하기 위한 전문가 설문을 실시하여 전국 자연휴양림을 대상으로 현황설문조사를 실시하였다. 공통성 추출을 위한 요인분석 결과, 4개 요인으로 구분되어 각각의 명명을 변수의 속성과 크기에 따라 이용실적 지표요인, 교육적 지표요인, 내부 활동적 지표요인, 수용 잠재적 지표요인으로 명명하였다. 그리고 추출된 요인점수를 통하여 $85{\times}4$행렬의 군집분석을 시도하였다. 그 결과 5개 군집으로 최종 유형이 분류되었다. 본 연구를 통한 결과는 유형별 휴양림 운영방안 및 관리의 기초자료로 제공되어질 수 있을 것이다. 그리고 향후 자연휴양림의 조사지에 대한 선정 시 기초자료로 참고할 수도 있을 것이며, 또한 전국 자연휴양림의 유형을 제시함으로써 향후 휴양림 적지 선정에 있어서도 기초자료로 제공될 수 있을 것이다. Twenty years have passed since the adoption of natural recreation forests and each forest has its own characteristics. However, there is hardly any classification among the natural recreation forests. The purpose of this study is to classify the forests by considering the supplier's perspective as well as the user's perspective in order to provide fundamental materials for the operation of the natural recreation forests. A factor analysis was conducted to identify the common characteristics of the selected twelve variables by pre-selection and survey of experts. K-means cluster analysis was conducted among those factors to classify the natural recreation forests in Korea. Four factors were drawn after the factor analysis and the factors were named according to the variables and sizes as 'The use performance and visiting condition factor', 'Education and settlement factor', 'Internal activation factor' and 'Potential factor' In addition, the cluster analysis of an $85{\times}4$ matrix was conducted for the points of the drawn factors and the final classification consists of five groups. The results of this study may contribute to providing fundamental materials for the operation and management of natural recreation forests. Also, it may act as a reference when investigating the natural recreation forests of Korea. Proposing the classification natural recreation forests could be helpful in selecting the proper recreation forest in the future. Based on the established model, fundamental materials could be provided to improve the profitability of the natural recreation forests by effectively expanding the number of tourists, creating new natural recreation forests and proper maintenance and management.

Extraction of knowledge, expecially in the form of rules, from raw data is very important in data mining, the aim of which is to help users who feel the lack of knowledge in spite of the abundance of data. Logic minimization tools are ones which derive optimized knowledge given ON set and DC set. First, the parallel expansion scheme of logic minimization is extracted and used to obtain initial knowledge. Then sorting, reduction, and rule expansion schemes are designed and applied to the initial knowledge to get final rules, which are successfully applicable to real world data. The prototype system based on this new approach has been experimented with real world data to show that it is as practical as conventional long studied decision tree methods like C4.5 system.

This research is written for offering an approach to activate the stagnated industry of the tourist farm through analysis of the current operational problems and situation on some existing tourist farm nominated as such by the authority. There will be some considerations from three different categories : local autonomous groups, tourist farm associations and farm owners. On the other hand, it is assumed that this research can also be utilized as a basic material for activating the tourist farms in the suburban area of Taegu City. The operational problems in the suburban area of Taegu City are as follows : lack of a specialized product development, the farm operation fund, lack of operational or management ability, lack of public information, etc. There are other problems regarding law, institution and supporting : complexity of the current system involving all kinds of permission, shortage of financial and taxation supporting, lack of training an expert manpower, lack of ability and cooperation of a deskclerk in charge, etc. Here are some suggestions taking into consideration a respective sector of local autonomous group, tourist farm associations and farm owners for activating the tourist farms in the suburban area of Taegu City. First, a mental turnabout toward a tourist farm is needed from local autonomous groups. The law and institutional base should be arranged while the financial and taxation support is materialized. Second, tourist farm associations should amend or reinforce the existing institution to refresh the current recognition toward the tourist farm through many publicity activities. On the other hand, they should develop the overall tourist farm industry into a better service industry of the rural community by keeping an active system of cooperation with other related groups. Finally, It is advised that they should conceive farms and facilities which can symbolize the tourist farm from the stage of the first construction. In addition to a four-season souvenir development, an effective publicity activity and rational investment management. Above all, they should train themselves in terms of a service spirit before they see the prosperity of the tourist farm community.

수목원은 자연에서 생육하는 식물의 조사, 수집, 증식 보전을 통해 식물 종을 보전하고 식물 관련연구를 수행하며 식물을 일정한 야외나 실외 공간에 전시하여 국민들에게 식물에 대한 교육과 휴식공간을 제공하는 시설물이라고 정의하고 있다. 이러한 수목원의 비시장적인 가치를 추정하기 위해 CVM 기법을 이용하여 대구수목원의 경제적 가치를 추정하였다. 가치추정의 방법은 대상재의 설정, 지불수단의 결정, 지불의사 유도 방법 결정, 가상적 상황설정, 설문, 분석, 추정액 도출의 순서로 진행하였으며 대구광역시에서 운영하는 대구수목원의 비시장적인 환경의 가치를 현재의 통화액으로 추정하기 위해 수행 되었다. 가치 추정은 DBDC방식으로 진행 하였으며 분석의 방법은 도출된 추정치가 비교적 안정적으로 알려진 logit분포를 가정한 함수의 분포 형태별로 각각의 추정액을 도출 하였다. 통계적 적합성을 바탕으로 1인당 대구수목원을 방문하여 얻는 연간 휴양의 가치는 WTPmean 12,718원, WTP median 11,033원, WTPtruncated mean 11,468원으로 추정할 수 있었다. 이를 토대로 대구수목원이 제공하는 연간 환경의 가치는 약 160억 원에서 190억 원으로 추정 할 수 있다. 이러한 대구수목원의 환경에 대한 가치추정법은 그 연구 대상지나 대상 재화만 변경하여서 기타의 환경재 가치 추정에도 충분히 적용 가능할 것으로 판단한다. An arboretum is defined as a collection of facilities that conserve plant species by surveying, collecting, and proliferating and preserving the plants in nature, perform diverse researches on plants and display the plants in exhibition spaces or outdoors as well as provide the public with educational programs and refreshment spaces according to the laws concerned. The public, however, recognizes the exhibition and education functions on plants of arboretum more importantly compared with the roles to survey, collect, and proliferate plants as regulated by the laws. In particular, arboretum plays a role to offer a pivotal educational place in urban area where the public can obtain an hands-on experience and understanding on a wide range of plant species and natural environment. The study aims to estimate the non market environmental values of Daegu Arboretum operated by Daegu Metropolitan City government by using the Contingent Valuation Methods (CVM), which yields the current monetary estimates for the arboretum. The value estimation was undertaken by using the Double-Bound Dichotomous Choice (DBDC) method, and each estimated value was derived from respective functions based on a logit distribution known to include relatively stable estimates according to the shape of the distribution. Considering the statistical fitness test results, the author estimated the amounts of the Willingness To Pay (WTP) such as mean WTP of 12,718 KRW, median WTP of 11,033 KRW, and truncated mean WTP of 11,468 KRW, which represented the annual recreational values per a person visiting Daegu Arboretum respectively. The analysis showed that Daegu Arboretum created the annual environmental values which were estimated to be approximately 16 to 19 billion KRW. The study also has an implication that the valuation method for the environment of Daegu Arboretum may be effectively applied for estimating the values of other types of environmental goods by altering the locations or goods to be analyzed.

산림과 계곡 속에서 휴양을 통한 개인의 자아개발과 주위사람들과의 교류의 장소, 환경에 대한 교육의 장소, 심리적 안정과 정신적 편안함을 누리기 위한 장소로서 자연휴양림이 각광을 받고 있다. 1988년부터 급격히 설립되기 시작한자 연휴양림은 이용객 또한 증가되고 있으며, 지역적 여건이나 환경적 여건에 따라 그 특징이 세분화 되어 가고 있다. 그리고 주 5일제의 영향과 휴식, 여가, 웰빙 등에 대한 관심 증대 그리고 여름이나 행락철 또는 주말에 집중되는 이용객들로 인해 조용히 심신의 휴양을 원하는 방문객들은 기대한 휴양 욕구를 충족하지 못하였다. 이에 따라 본 연구에서는 이용객의 효율적 만족도 향상을 위해 전국 국 공유 85개 자연휴양림을 군집분류한 선행연구를 바탕으로 각각의 군집별 만족도의 차이를 검증하였다. 설문은 각각의 군집별로 적절히 배분하여 1,132부를 회수하여 유효한 설문지 1,015부를 분석에 이용하였으며, 설문의 신뢰성과 구축된 모형식의 통계적 적절함을 검증하였다. 그 결과, 군집별로 만족도에 영향을 미치는 독립변수의 순위에 유의한 차이가 있음을 알 수 있었다. 수용잠재적 자연휴양림군집, 내부활동적 자연휴양림군집, 내부활동, 수용잠재혼합 자연휴양림군집에서는 휴양 및 피로회복의 변수가 만족도에 가장 큰 영향력을 미치고 있으며, 그 외의 변수들의 영향력 순서도 다름을 알 수 있었다. 그리고 이용실적지표 자연휴양림군집에서는 방문비용의 적절함이, 교육적지 표 군집에서는 주변관광지와의 연계성이 만족도에 가장 큰 영향을 미치고 있음을 알 수 있었다. 이러한 연구 결과는 군집별로 차별화된 자원의 배분을 통하여 이용객에 대한 효율적인 만족도 향상을 위한 서비스 및 자연휴양림 환경의 정비작업에 우선순위를 제공하여 줄 수 있을 것이다. Recreation forests are in the spotlight as the place for personality development, mind and body comfort, companionship, and environment education in forests and valleys. Visitors to recreation forests have been on the increase along with booming in recreation forest building since 1988. Recreation forests are being categorized according to some features such as regional and environmental condition. Recreation forests, however, have not met the expectations of some visitors who want to take a rest with calmness due to the influence of the 5-day-work-week system, increasing interest in rest, leisure, and well-being, and users converge during weekends, summer, and the tourist season. In order to improve visitors' satisfaction efficiently, this study surveyed the level of satisfaction in each cluster based on the precedent study which had classified 85 national or public recreation forests in Korea into clusters. Questionnaires were distributed properly to each cluster and, of the 1,132 questionnaires collected, 1,015 were valid and used for analysis. Reliability of questionnaires and statistical validity of the model were verified. As a result, there are meaningful differences in the ranking of independent variables which affect the level of satisfaction according to clusters. Variables in rest and fatigue recovery have the strongest influence on the level of satisfaction in the clusters of potential factor, internal activation factor, and mixed potential capacity factor. In the use performance and visiting condition factor cluster, appropriateness of visit cost is most influential and, in the education cluster, connectivity with tourist attractions around it is most affective. These results can provide priority in services and maintenance of recreation forests for improving the level of satisfaction and differentiate the distribution of resources according to clusters.
