개느삼은 소나무 수관하에서 생육하는 절멸위기종의 하나이다. 본 연구에서는 강원도 양구군 내 개느삼 자생지의 상황을 식물상과 식생을 파악하고 개체군 보전을 위한 기초지식을 획득하는 데 있다. 강원도 양구군 비봉산 개느삼 보호지구의 식물상과 식생은 2003년 8월과 2008년 5월에 3개의 각각 다른 자생지를 대상으로 조사하였다. 조사지역에 자생하는 식물은 총 27과 40종 7변종인 것으로 조사되었다. 본 조사지의 식생은 전형적인 온대북부의 소나무림으로서 토양습도는 낮고, 냉온대지역의 경사면 지역으로 조사되었다. 본 조사지는 한반도에만 한정적으로 분포하는 개느삼 보전을 위해 매우 중요하다. 그러므로 장기생태관측을 통한 연구를 통하여 보전지구로의 지정 등의 보전방안이 시급히 마련되어야 할 것으로 생각된다.

유네스코(UNESCO: United Nations Educational, Scientific, and Cultural Organization) 세계유산 가운데 자연유산이 차지하는 비율은 문화유산에 비하여 매우 적다. 우리나라에서 처음으로 제주 화산섬과 용암동굴이 7번과 8번의 기준에 부합하여 지난 2007년에 유네스코 세계자연유산으로 등재되었다. 본 연구는 우리나라 지질유산에 대한 현황과 관리 및 보존 사례를 분석하고, 향후 지질유산 보존을 위한 중장기 추진 전략과 개선방안에 대하여 고찰하였다. 천연기념물로 지정되어 국가지정문화재로 보호받거나 지질공원과 같은 새로운 지질유산의 활용시스템을 도입하여 효과적인 교육과 홍보를 할 수 있는 방문객센터 건립을 통한 지질유산의 교육과 활용이 절실히 필요하다. 이 연구에서는 갯벌로 유네스코 세계유산으로 지정된 '와덴해(The Wadden Sea)'를 직접 방문하여, 세계유산 현장을 조사하고 관리를 책임지고 있는 전문가들과의 인터뷰를 통해 얻어진 자료를 정리하였다. '와덴해'의 성공적인 세계유산 관리와 보존을 위한 정책은 크게 세 가지 요인으로 요약할 수 있다. 첫째, 연구와 모니터링을 위한 통합관리시스템과 공동사무국의 운영이고 둘째, 지질유산의 홍보와 교육을 위한 방문객센터의 활성화, 그리고 마지막으로 장기 발전계획에 따른 전문가들의 다양한 연구과제와 프로젝트의 실행이다. 이 연구는 우리나라 지질유산의 현황을 살펴보고, 그 가치를 증진하고 보존하기 위한 방안을 모색하는 정책적 대안을 마련하고자 수행되었으며, 우리나라 지질분야 자연유산의 중장기적인 정책적 결정에 기여하고자 한다.

Double-diffusive convection inside a triangular porous cavity is studied numerically. Galerkin finite element method is adopted to derive the discrete form of the governing differential equations. The first-order backward Euler scheme is used for temporal discretization with the second-order Adams-Bashforth scheme for the convection terms in the energy and species conservation equations. The Boussinesq-Oberbeck approximation is used to calculate the density dependence on the temperature and concentration fields. A parametric study is performed with the Lewis number, the Rayleigh number, the buoyancy ratio, and the shape of the triangle. The effect of gravity orientation is considered also. Results obtained include the flow, temperature, and concentration fields. The differences induced by varying physical parameters are analyzed and discussed. It is found that the heat transfer rate is sensitive to the shape of the triangles. For the given geometries, buoyancy ratio and Rayleigh numbers are the dominating parameters controlling the heat transfer.

The need of the life be healthy is increasing to the human life prolongation. There are lots of companies using the use of environment-friendly material as the sales strategy today. But a consumer is insufficient of the information about the environment-friendly ingredient. The level of Consciousness for the consumer standard of living and health got higher recently. And the interest about the furniture material comprising the residential space rose. I consider the consumer changing mind the safety of the conservation of the environment and mankind. Also, future of the environment-friendly material can say that is light if develop various the environment-friendly material description and accomplish the Higher Value-added of resource.

Genetic diversity within the natural populations of Daba ecorace of Antheraea mylitta Drury was studied using individual silkworms collected from the South Singhbhum district of Jharkhand state of India with 21 inter simple sequence repeat (ISSR) primers. A total of 148 bands were produced, of which 79% was polymorphic. The pair wise genetic distance among the individuals varied from 0.186 to 0.329. The dendrogram grouped the individuals into 3 major clusters. Nei's heterozygosity analysis revealed 0.265 ${\times}$ 0.18 variability within the population. The high genetic variability present within the natural population of Daba ecorace of A. mylitta is indicative of their adaptational strategy in nature and have much importance for in situ conservation as well as utilization in breeding programs.

The purpose of this study is to introduce the storytelling project for conservation and improvement of rural tourism. So, in this study, the current Jeju Batdam and storytelling planning are examined and the storytelling project presented in planning is also examined. And this study propose the storytelling implementation through the case study related in jeju. Its findings are as follws: 1) Storytelling exhibits principles of narrative structure(exposition, complication, climax and falling action) in various fact, and has shown tendency to structuralize a story. 2) It can be said that storytelling is deeply related with people's associations of their inner mind. 3) In order to convey a story in a more convincing way, storytelling a naming strategy based on a rhetorical technique, which has been shown to positively influence creating unique Jeju Batdam area.

As conservation of global environment has becoming a major outstanding issue of the world, the International Maritime Organization(IMO) has been legislation a convention for prevention of air pollution from ships. By the new convention, use of air pollutants such SOx, NOx, Freon and Halin Gas shall be restricted. In this regards, analysing these requirements of the convention is required as the cinvention will also be applied in restriction of descharging exhaust gases from ships by estsblishing a requirement of Sox and NOx discharged. The purpose of this study is as follows; 1) Introdcuing of the backgrounds of legislating the convention for prevention of air pollution from ships and major contents of the convention and a countermeasuures in the convention by Korea 2) Reviewing by analyzing the influence in domestic industries concernd by restriction of SOx, NOx in exhaust gases and sulpher content of fuel oil 3) Preparing a countermeasure in the convention properly.

This study has been designed to develop a health behavior scale. Data were collected through a survey over a period of two month period. Subjects who participated in the study were 298 Korean adults. The author used a convenience sampling method. The analysis of the data was done with SPSS PC for descriptive statistics and factor analysis. Initially 34 items were generated from the interview data of twenty one adults and from literature review and survey. This preliminary scale was analyzed for a reliability and validity. The results are as follow : 1. Crombach Coefficient alpha for the 30 items was .7907. 2. Factor analysis was done in order to confirm construct validity and nine factor were extracted from the results. These contributed 54.4% of the variance in the total score. 3. Nine factor label were 'exercise' 'stress management' 'energy conservation' 'limit in liking' 'selection of food' 'ingestion of natural food' 'health examination' 'relaxation' and 'nutrition'. The author suggests that this scale could be adequately applied in assessing the health behavior of Korean adults. The results of using this scale in a study can contribute to designing an appropriate health promotion strategy.

Utilization of renewable energy is becoming increaingly important from the viewpoints of environmental protection and conservation of fossil fuel. However, the generating power of renewable energy is always fluctuating due to the environmental status. This paper presents a scheme for supervisory control of wind generation system with the energy storage and STATCOM to reduce the power variation. In this paper, we especially concentrate on constant power output control of wind generation system. In order to achieve this purpose, the coordinated control strategy between different types of energy storage system and reactive power compensation device. The proposed control scheme has been validated by PSCAD/EMTDC simulation. As a result, the proposed scheme can handle the power output of wind generation system with a constant value.
