There are islands about 3,200 in Korea surrounded by the sea side. The region of islands is the transition areas which are a border in the land and marine ecosystem. It is rich in biodiversity depending on the interaction among inland, sea and atmosphere. However, it is worried that damages of marine environment is increased because the more national income and demands ofmarine leisure increase, the more development projects are grown in marine areas. Also this trends are extending in island areas. Incheon Metropolitan city has huge island areas which are both inhabited and deserted islands. The range of island areas is very wide, so it is difficult for the city government to manage environment in the island areas. Therefore, this paper analyzed and discussed the actual conditions about managing marine environment at island areas.

갯대추(Paliurus ramosissimus (Lour.) Poiret)는 갈매나무과에 속하는 낙엽관목으로 드물게 교목으로 자라며, 우리나라에서는 제주도에만 분포하는 것으로 알려진 희귀식물이다. 이 종의 주요 분포대는 동아시아의 열대 및 아열대로 제주도는 위도 상 북한계로 알려져 환경부 지정 보호식물 제 39호로 지정\ulcorner보호하고 있으나 자생지에 대한 구체적인 조사가 이루어진 바 없다. 따라서 본 연구는 자생지의 현황과 생육상황을 파악하여 자생지 보전에 기여하고자 실시하였다. 갈매나무과는 세계적으로 58속 900여종이 분포하고, 갈매나무속(Genus Rhamnus), 헛개나무속(Genus Hovenia), 대추속(Genus Zyzyphus) 등이 주요 속으로 알려져 있으며, 그 중 갯대추속(Genus Paliurus)은 과실이 건과이고 날개가 있는 특징으로 다른 속과 구별된다. 꽃은 양성화로 7월~9월에 피고, 화서는 수 개의 꽃이 달리는 취산화서, 열매는 반구형으로 과병에 연한 갈색의 복모가 있으며 얕게 3부분으로 갈라져 각 실마다 편평한 공모양의 종자가 1개씩 들어있다. 갯대추 자생지는 제주도의 동부지역인 북제주군 구좌읍 김녕에 1개소, 남부지역인 남제주군 남원읍 태흥에 1개소, 서부지역인 북제주군 한경면 용당에 1개소, 한경면 용수에 1개소, 한경면 신창에 3개소 및 남제주군 대정읍 일과에 2개소 등 총 6지역 9개소였다. 분포지는 해발 20m이하의 해안가 토심이 얕은 암반 위였으며, 주로 해수의 영향을 직접적으로 받는 곳이었다. 생육상황을 조사한 결과 바다 쪽으로 갈수록 수고가 급격히 낮아지는 경향을 보였으며, 최소 0.3m, 최대 4.5m였고 평균 1.6m 정도였다. 수반종으로는 순비기나무와 갯기름나물, 갯까치수영 등 해안식생의 구성종이 대부분이었으며, 돌가시나무, 상동나무 등도 혼생하는 것으로 조사되었다. 자생지 위협요인으로는 양식장 시설, 도로개발, 해안매립 및 쓰레기 투기 등과 같은 인위적 간섭과 상동나무 등 주변식물의 피압이 주 요인이었다. 한편 갯대추는 희귀식물로서 뿐만 아니라 해류에 의해 전파되는 종으로 알려져 있어 제주도의 식물지리학적 연구에도 좋은 연구대상이 되고 있으므로 종 보전대책 및 자생지 보호에 대한 추가적인 연구가 필요하다.

The location of tourist function is influenced by the accessibility of fishing villages and tourist potential in the villages. In Jeju island, the accessibility of fishing villages is not enough of a difference, therefore tourist potential in the villages has a dominant influence on the tourist location. In the location of the tourist function, there is all the difference between sea or land. Because sea and land are a remarkable contrast in physical condition and tourist activity space. Consequently, the basic types of the tourist location are sea-oriented, land-oriented, sea land-oriented. Besides, fishing villages adjacent to the beach and islands are to be the types of the tourist location. The former is not central fishing village in the tourist location, the latter is not good in the accessibility of the basic three types. And the location of the tourist function has a dominant influence on the difference of tourist fishing villages, therefore the types of the tourist location is to be the types of tourist fishing villages.

The purpose of this study is to determine the weights of the factors for landslide susceptibility analysis using artificial neural network. Landslide locations were identified from interpretation of aerial photographs, field survey data, and topography. The landslide-related factors such as topographic slope, topographic curvature, soil drainage, soil effective thickness, soil texture, wood age and wood diameter were extracted from the spatial database in study area, Yongin. Using these factors, the weights of neural networks were calculated by backpropagation training algorithm and were used to determine the weight of landslide factors. Therefore, by interpreting the weights after training, the weight of each landslide factor can be ranked based on its contribution to the classification. The highest weight is topographic slope that is 5.33 and topographic curvature and soil texture are 1 and 1.17, respectively. Weight determination using backprogpagation algorithms can be used for overlay analysis of GIS so the factor that have low weight can be excluded in future analysis to save computation time.

Although tourism has been quite popular as development strategy, the outcomes may vary dependent upon managing stakeholders involved. Thus, stakeholder management has been the subject of growing research interests recently. Collaboration theory was suggested as an alternative to this question; however, collaboration theory may provide potential benefits, it lacks in consideration into stakeholder power relations. The purpose of this paper is two foleded. One is to examine critically collaboration theory in the context of tourism development, and address the necessity of stakeholder analysis framework, and the other is to provide the framework. This paper argues that careful analysis of stakeholders from diverse perspectives should be done in advance, and presents stakeholder analysis framework which consists of six analysis indicators: interest, perspective, power base(resource), involvement, influence, and legitimacy. The framework consists of three stages: (1) identifying stakeholder, (2) assessing stakeholder, and (3) establishing strategies. It is argued that the framework in this paper can be useful to analyze stakeholders and to set up strategy for more collaborative tourism development.

We investigated the genetic variation in Stewartia koreana Nakai by examining 61 I-SSR amplicons in 120 individuals distributed among six natural populations in Korea. The overall percentage of polymorphic I-SSR amplicons was 81.9% and mean number of amplicons per I-SSR primer was 12.2. Levels of genetic diversity within 6 populations were similar each other[Shannon's Index $0.358{\sim}0.467$(mean: 0.407)]. The Mt. Obong population had the highest level of genetic diversity and was most distinctive from the other populations. Most variation existed among individuals within population(88.2%). Genetic differentiation among populations(${\phi}_{ST}$) was 0.118. The UPGMA dendrogram based on the genetic distance failed in showing decisive geographic relationships.

Mt. Apsan is well known to be one of the most popular tourist sites around Daegu. Annually, more than 16 million persons visit Mt. Apsan. Although, in the mountain there are varieties of geomorphic and geological resources, there has been less concern to utilize the resources for geo-tourism. For example, there are about 10 valleys within Mt. Apsan and various landforms are scattered around the valleys. In this context, this study, based on field surveys centering around Gosangol valley, Anjiranggol valley and Dalbigol valley, focuses on exploring ways towards developing Mt. Apsan as an example geo-tourist site. The main findings are as follows: 1) The main landforms of Mt. Apsan include river cliff, cavern, free face, mud crack, ripple mark, fold, sheeting joint, talus, alluvial fan, pot hole, fault line, gnamma, columnar joint and metamorphic rock. 2) The guide notes on the landforms are developed. 3) In order to raise a learning effect of visitors on geomorphic resources, 9 nature trails are designed according to valleys and the length of visitor's stay.
