  • The influence of starvation on morphological change of the red sea bream larvae was examined at Song-ji fish hatchery, Tongyong-Gun, Kyongnam Provice in July 1988. The results obtained are as follows: 1) The larvae of red sea bream began to feed on rotifers in 2 days after hatching. In case of non-feeding, all of the larvae died in 5 days after hatching and the larvae which feeding delayed 1 and 2 days from normal first feeding schedule also died 100 in 6 days after hatching. 2) With the exhaustion of the yolk, the total length, body length, myotome height and gut height of unfed larvae decreased. 3) The ratio of height to myotome height in unfed larvae has declined most rapidly compare to other demensions while starving. At 5 days after hatching, the ratios of these of starving larvae and fed larvae were 0.306 and 0.010, respectively. 4) The morphology of starving larvae at 6 days after hatching are characterized as sharpened jaw, projected edge of lower part of clavicle and slender gut.

  • Jirisan National Park was designated on December 29, 1967 as the first national park in Korea and that caused continuous conflicts between the violation of the right to hold property in this area due to several regulations following the designation and the nature preservation for the value of heritage for descendants. Thus, the objective of this study is to find a proposal for making decision based on the rationality that is able to solve these conflicts. To achieve the objective of this study, this study applies a game theory that supports a reasonable decision making process for solving these conflicts between interest groups around Jirisan National Park in which the component of this game consists of Jirisan National Park, residents, and interest groups. The Nash equilibrium obtained by the analysis of the strategy of interest groups for the use and preservation of forests and its rewards from the strategy as an nonecooperative game showed a behavior that chases their own benefits and causes lots of troubles. However, in the case of the results obtained from a cooperative game based on the strategy that includes some public interests accepted by interest groups and its rewards, it represented an aspect that solves conflicts through achieving a strategical set, which shows a win-win outcome even though the results of this cooperative game may present less rewards than that of the Nash equilibrium. Whereas, if there exists the public interests accepted by interest groups and truth for protecting such public interests, it is considered that it becomes a way that solves present structural troubles in the National Parks in Korea due to the fact that there exist uncertainties caused by the human rationality.

  • 본 연구는 농천어메니티의 개념을 토대로 농촌주민과 도시민의 가치라고 할 수 있는 정주기능으로서의 생활자원화와 방문가치로서의 관광자원화로 구분하고, 이를 토대로 도시민과 농촌주민, 전문가들을 대상으로 농촌자원의 중요도와 순위적 관계를 분석하였다. 구체적인 연구결과를 살펴보면 다음과 같다. 첫째, 농촌자원을 자연적 자원과 문화적 자원, 사회적 자원으로 구분하여 37개 자원을 설정하였다. 이러한 농촌자원은 농촌어메니티를 형성하거나 형성에 영향을 미치는 대상이라고 볼 수 있다. 둘째, 이러한 농촌자원은 농촌주민과 도시민이 지닌 가치에 기초하여 생활자원적 가치와 관광가치적 가치를 동시에 혹은 차등적으로 지닐 수 있다. 이러한 관점은 농촌자원에 대한 중요도 평균에 대한 차이검증(t-test)을 수행한 결과 전체 자원의 56.8%에 해당하는 21개가 유의미한 차이를 보인 결과에 의해 지지를 받는다. 셋째, 농촌자원에 대한 순위적 상관관계분석에서도 전문가와 전체집단에서 생활자원과 관광자원에 대한 순위상관관계가 의미가 없는 것으로 나타나 위의 두번째 결과를 지지하고 있다. 이러한 결과는 농촌자원의 개발 방향과 가치부여가 자원의 속성에 따라 차등적으로 진행되어져야 함을 보여준다. 다섯째, 농촌자원의 유형을 생활자원화와 관광자원화에 대한 중요도의 표준화 점수에 기초하여 4개 유형(유형 I~IV)으로 구분하였다. 이러한 유형별 자원중요도를 고려하여 농촌마을의 개발목적에 비추어 생활자원형이나 관광자원형과의 연계를 통해 마을의 정체성과 특성화에 기여할 수 있도록 해야 할 것이다.(요약 및 결론에서 발췌)를 고지도와 지리지.읍지를 통하여 살펴봄으로써 변한 것과 변하지 않는 것을 분석하여 시대상의 복원과 지역사회의 정체성 확립에 일조하고자 한다.곡물의 여러 줄기가 합수하고 물이 역류하지 않으며 잘 감아도는 곳으로 표현할 수 있다 이러한 명당의 기본적인 원리는 장풍(藏風)과 득수득파(得水得破)이다. 장풍과 득수란 '국'(局), 즉 산줄기와 수계로 이루어진 일정한 범위 속에 만물이 생태계 속에서 살아가는 모습인 '체형(體形)'의 의미가 나타나야 한다는 것이다. 그러나 이러한 의미는 시대에 따라 달라질 수 있는 것이다.면적의 52%를 점유하여 감자 재배지의 핵심지를 이룬다. 4. 한국 감자 재배지역 중심지의 지리적 특징은, 높은 산지지역의 산록완사면에 밭작물로 재배된다는 점과 교통이 불편한 지역으로서 도시화와 산업화 지역의 그늘 지역이 대부분이다. 강원도의 감자 재배지는 감자재배에 적합한 자연환경과 화전농업의 전통, 감자 재배기술의 전파, 중앙정부와 지방정부가 지원하는 각종 연구소 분포와 영농지도, 씨감자 생산과 협동조합의 판로 개척, 도로 개설과 포장 등의 인문지리적 요인이 영농조건을 개선하고 감자 판매를 위한 시장접근을 용이하게 하여, 남한 최대의 감자 재배지역을 형성하였다. 제주도는 산지지형과 따뜻한 기온으로 2기작이 가능하고, 감자가공 공장설립과 교통발달에 따른 육지 시장과의 접근이 용이해졌기 때문에 남한에서 2번째로 큰 감자재배지역이 되었다.(요약 및 결론에서 발췌)그람양성균에서 효과적이었으며, 농도별 항균력시험 결과 농도가 증가할수록 비례하여 저해율도 증가함을 알 수 있었다. 첨가농도를 달

  • The Jeongdori windbreak forests of Wando island, located between the sea and the land, are very important as ecological succession areas that protect cultivated lands and fishing villages. Among the Jeongdori windbreak forests, the rocky seashore areas are occupied by Sageretia theezans mantle community, and their inner sections by sub-tree layers such as Ligustrum japonicum and Ligustrum obtusifolium. More specifically, the inner sections of the rocky seashore areas were found to be the habitat of Ligustrum japonicum-Quercus variabilis community, Ligustrum jarponicum-Viburnum erosum community, Ligustrum japonicum-Cinnamomum japonicum community, Cinnamomum japonicum-Carpinus tschonoskii community, and Pinus densiflora-Viburnum erosum community. The average height of tree layers of the Jeongdori windbreak forests is 10.3m, and the average diameter at breath height are 30.3cm. Though the windbreak forests was artificially made, it is now virtually natural forest and deserves protection for ecological reasons. Designated as a scenic spot 3, it is always in the danger of being damaged by frequent tourist visits. So the Jeongdori windbreak forest needs to be continuous maintenance and management by the National Park Service. Considering of the precious cultural treasures of the famous pebble stones covering Gugyedeung and the naturality of the Jeongdori windbreak forests, the Jeongdori windbreak forests as a scenic spot have to designated as the national monument in future and will preserve by the Cultural Properties Administration.

  • This paper aims to clarify the process of institutionalization of customary land ownership along with the expansion of coffee plantation in Dak Lak Province, Vietnam. Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production. The expansion of coffee plantation in Dak Lak have brought a severe competition of land resources, and resulted in the transition of land ownership scheme from customary commons by ethnic minorities to those of exculsive private assets which is secured by the state. Institutionalization of customary land ownership in Dak Lak, however, was differently happened according to the geography from the center of state power as well as the value of land resources. In this paper, the authors argue that institutionalization of customary land ownership in Dak Lak was a result of compromising between statemaking process in the frontiers and "everyday resistance" of ethnic minorities, comparing 3 geographically different ethnic minorities' communities.

  • A self-administered questionnaire survey and face-to-face interviews were conducted on 150 local residents belonging to seven villages, 160 visitors and 86 experts in order to analyze the attitudes of groups of local residents, visitors as well as experts toward the development plan of Sobaeksan Jarak-gil. Reliability analysis and one-way ANOVA were performed on the data collected by a questionnaire survey using IBM SPSS Statistics 20.0 after coding. The Duncan Test was conducted as a post-hoc test. Based on the analytical results, in economic terms, the expert group expected an increase in income, improvement in living standards and increase in expenditure for the maintenance of local infrastructure. In environmental terms, the visitor group was highly concerned about the disruption of the local natural environment and ecosystem, destruction of local properties and landscape, increase in water/soil/air pollution and increase in solid waste and noise. In social and cultural terms, the expert group had higher expectation for excavation of traditional cultural properties, instillation of local patriotism and pride, and the visitor group was highly concerned about a rise in crime, destruction of indigenous culture/increase in imitations, and induction of conflicts between residents. It is estimated that these results will be used as basic data for establishing the development plan of the mountainous ecological trail reflecting opinions of various groups.

  • Because of the oocIear family due to the rapid industrialization and the growth of husband and wife bah working, the base of the tradition that the parents, all of the famly or the hamet oonmunity bring up the infants together in the important time to the infarts has been collapsed in Korea. Because working mothers camot bring up their children by themselves they got stressed and housewives do not have the oonfidence in rearing their infants and the fathers are isolated from home and the chikten instead of being exempted from the responsibility of rearing children. Therefore the common and comprehensive rearing system should be made for solving the child-rearing problem. For solving these problems and for the desirable infant-rearing and education, the joint irlart rearing, whidl compensates for the life, education and furthermore the sdlool edJcation through the volur1ary participation, has been prepared altematively. Compared to the traditional rearing system, joint infant-rearing is not only operated by the residents with the dues paid by the union members but also makes children experience the life force of natu"e in themselves. So the preparation of the standard of the suitable environment design for the joint infant-rearing is required which is diffrent from the traditional standard of the environmertal facilities for the traditional rearing system. The concept of joint infant-rearing was defind in this study through the reference and the ooncept of infant edJcation which is in operation suocessfully in Italy and Sweden in order to understand how the ooncept of infant education has changed as the ages have dlanged. And the basic principals for the formation of physical envirorvnert and the spare design and the envirorYnertal oondition for the practical environmental design was also studied through the reference. And after study about the concept. figure and physical environmental suggestion, the concept, standard and element of joint infant-rearing environment design was suggested. And as the final conclusion, the design requirement of the envirorvnertal design for the joint infant-rearing was suggested.

  • This study aims at assessment of local festivals focused on analysis of operation program for local festivals held in Jeonbuk province. The subjects were 65 local festivals held in Jeonbuk in 2010 excluding festivals held in province, county, and town level, and those held with single purpose. Type of festivals were classified to type for residents' unity, tourism, industry, and special purpose type. The portion was industry type 36.9%, type for residents' unity 23.1% in the order. By theme, animal, plant, nature phenomenon, history, culture and tradition, special product, regional industry were classified - the portion was special product 36.9%, culture and tradition 24.6%, history 13.8%. Assessment of operation program was conducted with assessment indexes such as compliance with theme, uniqueness, diversity, effect of experience, size, educational effect, and entertainment. As a result, it appeared that because local festivals of Jeonbuk had high uniqueness, duplication of program between local festivals was very low and educational effect was comparatively high. On the other hand, because entertainment and effect of experience was very low, considerations of entertainment and effect of experience are necessary in planning of program.

  • The knowledge of native wild mushrooms traditionally using in Jeju Island, that have specific native environment and various biodiversity, was investigated. From Jeju and Seogwipo cities including 7 provinces 4 locals, so total 50 villages, data was collected in the entire area and voice of the 93 elderly people between the age of fifty and ninety were recorded. As a result, total 23 native wild mushrooms were used in which 2 species were poisonous mushrooms, 7 species were medicinal mushrooms, 2 species was used for folk religion, 2 species were not used for living but for attention and 12 species were edible mushrooms. Also, a total of 267 cases of traditional knowledge was collected, in which 197 cases were about edible mushrooms for 12 species, 43 cases were about poisonous mushrooms for 2 species, 16 cases were about medicinal mushrooms for 7 species. Interestingly, the fortune for agriculture was told depending on spore mass release of Cyathus stercoreus which grows in animal feces and compost. It is considered as the distinctive traditional knowledge of Jeju Island.
