Establishing conservation programs to protect and maintain populations of endangered species are not only a global trend, but also a pursuit endorsed by the Korean Environmental Conservation Act. This study evaluates the feasibility of alternative habitat patches for the endangered butterfly Parnassius bremeri. A portion of habitat of P. bremeri is expected to be fragmented and damaged due to the scheduled construction of the Sangju-Yongduk Highway. A trans fer of the habitat patches of P. bremeri is also scheduled. In order to select an alternative habitat patch, the Mark-Release-Recapture (MRR) method was used to simulate a patch transfer model. The connectedness between habitat are as and the survival of local populations were evaluated for each candidate habitat. It was found that metapopulations with patch distances of <250m showed a 50% connectedness and survival rate in local populations. P. bremeri were expected to migrate at an average distance of 300m. In addition, P. bremeri formed a metapopulation that exhibited intimate patch dynamics that promoted persistence among these patches. Possible candidate habitats including those recommended by local governing bodies were evaluated along with habitats that may counter problems arising from the damage done to the original habitat and habitats that may have a compensatory value equal to that of the original habitat. Based on these criteria, Ansa-myeon township office was selected due to its high scores. This scoring was based on a consideration of a wide range of variables that mark a successful transfer of habitat. These include the amount of funding available, the governing bodies of the possible alternative habitat, and the Expected collaborative effort of local citizens. This decision was collaborated on by incorporating the expertise of various fields of study including biology, ecology, biogeography, ecological engineering, landscape architecture, and social sciences. Therefore, it is suggested that in order to evaluate an alternative habitat for organisms, many social issues as well as ecological issues must be considered.

This study was conducted to investigate the actual situation of animal medicine use in Hanwoo farms, which were a total of 114 farms. Items surveyed were preference of animal medicine, choice criterion, purchase route, purchase frequency, antibiotics substitution products, etc. Data were collected from May to June, 2010. The kinds of animal medicine which preferred in Hanwoo farms is probiotics (40.4%). Whereas the lowest preference is immunizing agent (12.3%). There was significant difference among regional group (p<0.05), and the significant difference was also found in different farm size group (p<0.05). The factor of choice for purchase of animal medicine was efficiency (31.6%), first of all. There was significant difference among regional group (p<0.05). The purchase route of animal medicine was mostly supplied with the help of government (41.6%). The significant difference were showed in regional group (p<0.05). But that was not found in farm size group (p>0.05). The highest frequency at purchasing antibiotics was less than 1 time per 1 year (38.6%). There was statistically significant difference among regional group (p<0.05). However, there was not significant difference among farm size group (p>0.05). Probiotics of antibiotics substitution products was mostly preferred (50.9%).

This study attempts to characterize Taebaek mountainous region as a natural unit, relating to morphoclimatic milieu and landform development patterns of the mountains of each lithologic type. In the case of granitic mountains of Nothern parts of this region, the slopes presents more or less steep or irregular profile because of abundant microforms of exposed bedrocks and blocks. The development of such landscape is essentially due to differential weathering, associated with difference of joint density. In the case of gneissic mountains, the slopes are well regularized straight steep ones, due not only to generalized superficial weathering but also to massmovement of weathered materials. In the Middle parts of this region, especially in Taegwallyong area, with frequent alternations both of freezing-thawing and of snow accumulation-melting, the roles played by cryo-nival processes proved to be important in weathering of granite as well as in morpho-pedogenesis. In this area, weathered mantle, developed by cryogenic activity under humid condition of nival environment, covered almost all over the slopes. Although Southern parts of this region consist of limestone, on the mountainous volume, distribution of Karst forms are limited while predominate none karst forms such as cockpit type peaks, V-shaped type valleys dissecting steep slopes covered with thin deposits in thickness containing rock debris.

일반적으로 부산ㆍ강남지역의 연약지반을 논할 때에는 낙동강 하구 유역의 퇴적층 즉, 델타지역을 일컫는 경우가 많으며 부산의 용지난에 대한 대체 방안으로 많은 개발이 이루어지고 있다. 특히 연약지반의 심도가 아주 깊기 때문에 현장의 설계 및 시공에 많은 문제점이 노출되었고 이에 대한 다양한 연구가 수행되고 있다. 그 예로, 60년대 중반부터 시작된 박의 연구(1966)를 예로 들 수 있다. 그는 90년대에 들어서면서부터 이 지역 연약지반에 관한 본격적인 체계를 수립해오고 있는데 특히, 지반정보시스템 개발의 필요성을 역설하고 그 토대가 된 연구들(박 등, 1994; Park 등, 1997)은 앞으로의 지반공학의 새로운 연구방향을 제시한 것이라 할 수 있다.(중략)

최근에 조사된 연구에 따르면 한국 성인 암환자의 50∼60%가 민간요법 또는 대체요법을 사용하고 있으며, 그 중 70% 정도가 효과를 보았고 부작용은 거의 경험하지 않았다고 보고하였다고 한다. 가족 및 친지, 동료환자 및 매스컴이 주된 정보원이었고, 대부분이 경제적 부담이 된다고 응답했지만 월 50만원 이상 지출하는 경우가 50% 이상이었다.(중략)

Land Suitability Assessment can help to evaluate whether to preserve or to develop through analysis of various land characteristics. So, the evaluation index and method are very important for making the best result. The principle objective of this dissertation is to identify effective method that can make up for the distortion of land suitability value in the forest bordering the management area. The objective area of this study is comparative flat Jeungpyeong-gun. The procedures of the study are as follows. First, implement land suitability assessment as the normal index on Guideline. Second, verify land suitability grade about the forest bordering the management area. The third, redo land suitability assessment as two alternative index on $^*$Guideline. The fourth, identify effective method between normal index and alternative index. The results of this tests show that the development suitability value is higher than preservation suitability value in the forest bordering the management area near existing development area. For that reason, this study needed to use substitution index in order to make up for the weakness. The level of land price and distance from road were main considerations. Finally, the derivative model is as follows. The derivative model confirmed the best assessment method in the forest bordering the management area near existing development area.
