Korea's pet-related society has been fast growing without the base and preparations of socio-cultural animal welfare. For the most part, Korea's current public parks, in particular, have a space structure in which a lot of friction between the general public who are not fond of dogs and dog owners in public places has been happening unavoidably. A lot of countries that are taking a lead role in animal welfare have built dog parte that the general public and dogs can enjoy together. This research starts with the realization that the concept of 'dog park' needs to be introduced in Korea as more and more Koreans own dogs and other pets. This research aims to provide guidance for dog park planning by drawing a dog park planning model and to promote basics for co-existence of dogs and people in a park and set in place animal welfare early and raise the level of awareness. Total 7 types of dog put 56 planning items including dog zone, dog playground, and agility, and a selective matrix by which it is possible to select essential recommendatory optional items by each type of dog park were drawn in this research. Overall there were the highest needs in separated area for dogs in park. A dog park planning model is designed as follows. 1) To select a dog park type that was introduced. 2) To set up facilities applicable in common and planning items desired in advance by each type. 3) To zone dog park areas by the priority order of planning items that were introduced and to position necessary facilities. 4) To plan program that should be were introduced. A dog park was expected to take some positive roles such as providing opportunities to socialize dogs, activating social communities, more effective park management by participating local community members and so on.

본 연구의 목적은 북한산 국립공원 경계선 일대의 추이대를 탐지하는 기법을 개발하여 추이대의 폭을 조사하고, 시간경과에 따른 추이대의 폭의 변화여부를 조사하여 과도한 이용자의 집중과 주변부의 환경오염에 의한 추이대 식생의 피해 여부를 규명하는 것이다. 이를 위해서 1985, 1987, 1993년 5월 중순에 수신된 TM영상을 이용하여 계산한 정규식생지수(NDVI)를 도출하고, 버퍼링작업에 의하여 경계선으로부터의 거리별 NDVI를 산출하여 추이대를 조사하는 방법을 제시하였다. 연구 결과 본 연구대상지의 추이대의 식생은 생물계절(phenology), 인접지역의 토지이용의 영향을 받는 것이 확인되었으며, 1993년에는 1985년에 비해서 추이대의 폭이 약 2배로 증대되어 탐방객의 과도한 이용 등으로 인하여 공원경계부 인접한 식생 피해지역의 범위가 확대되고 있는 것으로 판명되었다. The purposes of this research were to find ways to detect ecotone between the Mt. Pukhansan National Park and adjacent urban residential areas, to measure the width and size of ecotone around the park, and to investigate temporal change of ecotone around the park. Normalized Difference Vegetation Index(NDVI) derived from TM data (May of 1985, 1987, and 1993) and the analytical capabilities of GIS were used to investigate the impacts of human activities inside of and outside of the bounadry of the park. Major findings of the study can be summarized as follows: First, ecotone around the boundary of the national park could be identified from NDVI-distance curves derived by a series of buffering operations with a GIS. Second, average width of ecotone around the park was nearly doubled during 1985-1993 period. Third, NDVI values of the park were about 14 percent higher than those of surrounding areas. Finally, it seems that the expansion of the ecotone of the park is related to heavy trampling of visitors and various types of environmental pollution of the adjacent urban areas.

The objective of this study is to investigate the characteristics of the location and prospects of the bear shelves built by Asiatic black bears in the Jirisan National Park. Previous researchers have been analyzed bear shelves in terms of places for resting and eating, but we are going to analyze based on the prospect-and-refuge theory. Characteristics of the sites of bear shelves are measured through field survey and topographic analysis by using digital elevation model (DEM). The normalized difference vegetation index (NDVI) is used to evaluate the optimum location of bear shelves in terms of crown density. Man-made objects are identified by viewshed analysis based on geographical information system (GIS). Findings of this paper can be summarized as follows. First, most bear trees are located deep inside of the mountainous national park, slopes of 30~40 degrees, altitude of 400~1,200m, and relatively low vegetation density with NDVI value of 0.4~0.6 compared to the average NDVI of the park. Second, the average height of bear shelves is 12.44m, or 74% of the average height of bear trees.They are located at suitable places to observe nearby trails and other park facilities. Third, man-made objects within the 100m radius of bear trees include lodge, bear training center, beekeeping camp, and hiking trails. Thus we may temporarily conclude that one of the main criteria of the bear tree selection in the park has been to identify optimum places for the monitoring of human activities in their habitat.

Korean goral (Nemorhaedus caudatus raddeanus) is one of the endangered species in Korea, and the rugged terrain of the Soraksan National Park (373㎢) is a critical habitat for the species. But the goral population is threatened by habitat fragmentation caused by roads and hiking trails. The objective of this study was to develop a potential habitat suitability model for Korean goral in the park, and the model was based on the concepts of fuzzy set theory and multi-criteria evaluation. The process of the suitability modeling could be divided into three steps. First, data for the modeling was collected by using field work and a literature survey. Collected data included 204 points of GPS data obtained through a goral trace survey and through the number of daily visitors to each hiking trail during the peak season of the park. Second, fuzzy set theory was employed for building a GIS data base related to environmental factors affecting the suitability of the goral habitat. Finally, a multiple-criteria evaluation was performed as the final step towards a goral habitat suitability model. The results of the study were as follows. First, characteristics of suitable habitats were the proximity to rock cliffs, scattered pine (Pinus densiflora) patches, ridges, the elevation of 700∼800m, and the aspect of south and southeast. Second, the habitat suitability model had a high classification accuracy of 93.9% for the analysis site, and 95.7% for the validation site at a cut off value of 0.5. Finally, 11.7% of habitatwith more than 0.5 of habitat suitability index was affected by roads and hiking trails in the park.

The purpose of this study are to develop a SDSS (Spatial Decision Support System) that can incorporate diverse opinions of stakeholders related the designation of protected areas (PA), and to employ the model for the readjustment of the boundary line of the Jirisan National Park of Korea. The SDSS would lead to more rational and less controversial decision-making during the expansion or removal of PA in Korea. Research methods are as follows. Firstly, to select evaluation criteria for SDSS for PA designation by using expert interview and literature survey. Secondly, to measure their preferences on the designation of additional PA or the removal of a part of PA based on the opinions of various stakeholders such as local residents, environmental groups, or public officials. Thirdly, to produce conservation priority maps based on a multi-criteria decision making technique. The SDSS would be used to rational decision making for the expansion of PA or the release of a certain part of PA by reflecting diverse preferences on biodiversity conservation and economic interest of residents. The visualization of conservation priority maps would also increase the efficiency of such decision making processes. The evaluation criteria for the expansion of PA for biodiversity conservation includes vegetation conservation value, wildlife conservation value, and the habitats of key species. The evaluation criteria for the removal of PA includes the proximity to roads and the boundary of PA, land use types, and conservation zoning of the PA. Preference weights are based on data collected from the Jirisan National Park. Both the conservation priority and removal priority maps are based on land parcels so that property rights of all parcels would be correctly represented.

Cytotoxic Effects of 7-O-Butyl Naringenin on Human Breast Cancer MCF-7 Cells

The effect of 7-O-butyl naringenin (BN), a chemically synthesized derivative of naringenin, was tested on the proliferation of human breast cancer MCF-7 cells. BN inhibited the proliferation of MCF-7 cells in dosedependent manner (IC50: 67.5±2.1 μM), resulting in an increase in the sub-G1 phase cell population. BN induced the generation of intracellular reactive oxygen species (ROS), which were reduced by pretreatment with Nacetylcysteine (NAC). BN also increased the phosphorylation of stress-activated protein kinase/c-Jun NH4-terminal kinase 1/2 (SAPK/JNK1/2), c-Jun, and p38. However, the phosphorylation of extracellular-regulated kinase 1/2(Erk1/2) was decreased in BN-treated cells. Pretreatment of cells with the specific inhibitors SP600125 and SB203580 diminished the BN-induced activation of SAPK/JNK1/2 and p38, respectively. These results indicate that the BN-induced cytotoxicity of MCF-7 cells is mediated by the generation of ROS as well as through the p38, SAPK/JNK1/2, and c-Jun activation signaling pathways. BN may therefore possess chemotherapeutic potential as an anti-proliferative agent.

With the development of Information Communication Technique, electronic commerce using PKIs is widely used over the Internet. The goal of access control is to counter the threat of unauthorized operations involving Web-server or data base systems. The RBAC(Role-Based Access Control) has recently received considerable attention as a promising alternative to traditional discretionary and mandatory access controls. In this paper we propose two methods, the RBAC system using attribute certificates and the RBAC system using SPKI certificates. And we analyze and compare the two methods.
