This study aimed to identify the aquatic and riparian factors associated with the presence/absence of the Eurasian otter in the Nakdong river basin, where the species is relatively more abundant than other otter species. Environmental factors and presence records were collected. Geographical Information System technology and chi-square test were used to compare environmental gradients in aquatic and riparian factors between presence and absence sites. Aquatic habitat attributes were evaluated with natural riverside sandbars and channel crossing artificial structures, the ratio of channel width to alluvial plain width, riverbed substrate, and flow diversity. Riverbank characteristics, bank materials, man-made embankment types, and land use/land cover of inland and riverside areas were selected as riparian habitat attributes. Compared to the aquatic attributes, riparian attributes were highly significant when assessing otter presence and absence sites, suggesting that conservation of suitable riparian areas to provide maternity and resting areas for otter species is essential in the Nakdong river basin. None of the aquatic attributes examined were statistically significant when evaluating otter presence or absence. These results indicate that the presence of suitable riparian area for resting and reproduction habitats is more critical to the presence of Eurasian otter than food availability in aquatic areas. To inform implementation of effective conservation actions, broad-scale factors, such as watershed attributes, would be needed to further assess habitat conditions of the Eurasian otter.

어떤 의미에서 제품은 다양한 정보와 에너지, 물질의 결합체로 파악될 수 있으며, 디자이너의 디자인행위는 디자인 프로세스를 통하여 제품의 이런 속성들의 수준을 결정하는 것이라 볼 수 있다. 즉 제품을 하나의 속성다발체로 생각할 때 각 속성들을 제어하고 조직화하고 최선의 상태가 되도록 결정하기 위하여 디자이너는 각 속성에 대한 다양한 정보를 필요로 하게 된다. 그러나 실제 디자이너가 이용할 수 있는 정보는 이전에 경험했던 내용을 바탕으로 한 직관이나 카다로그 등 이미 공개되었거나 일차원적인 자료에 의존할 뿐이며 있다하더라도 체계적이지 못하고 디자인과는 다른 입장에서 작성된 영업이나 마케팅, 개발부서의 입장이 중심이 된 정보가 대부분이다. 따라서 디자이너가 실제적으로 이용할 수 있는 디자인정보의 개발이 필요하며 이런 디자인정보의 효율적인 이용과 관리를 위하여 또 제품개발에 관여하는 여러 전문가와의 커뮤니케이션 인터페이스로서, 제품개발의 구심점으로 디자인정보시스템이 필요하다. 이런 연구배경을 바탕으로 구체적으로 제품계획의 의미와 제품개발 프로세스를 고찰하여 새로운 디자인 정보 시스템의 필요성을 이해하고 구체적인 개발방법을 위하여 제품을 디자인 정보 탐색의 기준으로 제시하였다. 다음 제품계획에 있어 제품의 개념 및 범주를 정의하고 제품을 둘러싼 기본적인 논리에 따라 제품속성을 규명하였으며 규명된 제품속성을 바탕으로 디자인 정보 모델을 만들고 이것을 기본으로 디자인 정보시스템의 프로토타입을 작성하였다. 마지막으로 작성된 프로토타입의 평가를 바탕으로 결론 및 추후연구과제에 대해 논하였다.

The purpose of this study is the practical application of landscape ecological indices to establishment of eco-village planning methodology. Planning an eco-village has to be carried out in the boundary of a small watershed that is defined by homogeneous ecological character. Because the small watershed is a landscape unit it can have unique ecological character. On this viewpoint, the spatial structure is analyzed by the ecological attributes of form, distribution arrangement and composition of the sub-landscape units. Among all of the sub-landscape units, a green tract of land is the main subject of the analyzing entity. Woodland or forest as a green tract of land is a source of biological species and materials. Therefore the ecological attributes of green patches are especially analyzed by landscape ecological indices. The selected landscape ecological indices are elongation, lobes, interior area ratio, convolution of perimeter and proximity of the green patches. These indices represent the state of ecological conditions and they will be the evaluation factors of the landscape ecological planning. These frameworks for landscape ecological planning apply to Obok and Ganggeum villages in Wanju-gun, Korea. A proposed planning was evaluated by the selected landscape ecological indices. Among the selected landscape ecological indices of green patches, perimeter convolution and proximity were increased. It means that the ecological condition of peen paches will be mon sound and green areas of the village will be expanded naturally. In addition to this connectivities among green patches will also be improved.

In this paper, a method of generating path planning map is developed using digitalized geographic information such as FDB(Feature DataBase). FDB is widely used by the Army and needs to be applied to all weapon systems of newly developed. For the autonomous navigation of a robot, it is necessary to generate a path planning map by which a global path can be optimized. First, data included in FDB is analyzed in order to identify meaningful layers and attributes of which information can be used to generate the path planning map. Then for each of meaningful layers identified, a set of values of attributes in the layer is converted into the traverse cost using a matching table in which any combination of attribute values are matched into the corresponding traverse cost. For a certain region that is gridded, i.e., represented by a grid map, the traverse cost is extracted in a automatic manner for each gird of the region to generate the path planning map. Since multiple layers may be included in a single grid, an algorithm is developed to fusion several traverse costs. The proposed method is tested using a experimental program. Test results show that it can be a viable tool for generating the path planning map in real-time. The method can be used to generate other kinds of path planning maps using the digitalized geographic information as well.

This study is an experimental study that examines the policy attributes that local governments should choose to manage the quality of life of rural residents. The analysis data used raw materials for the survey of the welfare status of farmers and fishermen surveyed by the Rural Development Administration. The analysis method used Quantile Regression. The policy attributes of public services were interpreted on the basis of Peterson (1981)'s theory of policy types and the discussion of Holland (2015). According to the analysis results, the higher the quality of life, the greater the importance of the relationship between the safety sector and the neighbors. The effective policy attributes for improving quality of life in rural areas are the policies of local governments where policy benefits can directly go to individuals, or lead to social improvement. It shows that the higher the level of safety and the quality of life of our neighbors, the greater its importance.

This study intends to analyze urban peoples' leisure choice attributes of rural areas from a rural demand perspective. For this purpose, this study investigates regional attributes considered in decision making processes for rural tourism destinations of urban residents using a conjoint model as a stated preference model. Based on literature reviews, two questionnaire surveys were conducted. The first questionnaire survey was performed in 4 cities including Seoul, Daejeon, Suwon and Chuncheon with 408 urban residents. The Second questionnaire survey was performed in 5 cities including Seoul, Chuncheon, Daejeon, Jeonju and Busan with about 1,060 urban residents. The study results suggest that the most important attribute in selecting rural ares for tourism are activity programs and convenience of facility, according to part-worth and vector model. The fitness level of model is 0.986, which is very significant. Among the 5 attribute's levels, the rural residents' kindness, the traditional and the ecological programs and the facilities about sign and lodging are more critical factors than other levels. Utilities of each levels decreases as cost and arrival time increases. Regarding the result of market segmentations, respondents having intention to visit can be divided into 4 group; (1) facility or program oriented type, (2) resident's kindness oriented type, (3) arrival time oriented type, and (4) negatively participant type. The results of leisure choice attributes can provide insightful information for regional planning strategies, such as selection of the type of market segments and the key factor of facility and space planning.
