  • Korean goral (Nemorhaedus caudatus raddeanus) is an endangered species in Korea, and the rugged terrain of the Sorksan National Park $(373km^2)$ is a critical habitat for the species. Since the goral population is threatened by habitat fragmentation, it is essential to establish a reserve for the isolated goral population. The objective of this study was to propose a reserve for Korean goral in the national Park We employed habitat suitability model, habitat capability model, and the concept of minimum viable population. The results of the study were as follows. First, the carrying capacity and optimal density of gorals in the national park were projected to be 449 gorals, and 251 gorals, respectively Second, since only one patch was projected to satisfy the criteria of minimum viable population (50 individuals/during 50 years), the long term extinction possibility of gorals in the site would be very high. Finally, the patch that satisfy the minimum viable population of goral was proposed as the core zone of the goral reserve and adjacent patches were included as buffer zones.

  • A Korean goral (immature, female) was presented with paraplegia following motor vehicle trauma. The patient was diagnosed with an L5-6 vertebral fracture-luxation based on digital radiographs. Surgical reduction and stabilization of the fracture-luxation were performed via a dorsal approach to the lumbar spine. It was confirmed in surgery that the patient had L5-7 spinous process fractures, L6 bilateral articular process fractures, and an L5-6 luxation. Free fragments were removed and the luxation was reduced. During reduction, caudodorsal dislocation of the L5 caudal vertebral end plate was discovered and the displaced end plate was removed. The L5-6 vertebral luxation was stabilized using pins and bone cement. However, the presence of an intact spinal cord was not confirmed. Two weeks postoperatively the patient became dyspneic and arrested. A necropsy was performed, which revealed that the surgical stabilization was intact. Pulmonary edema was identified and the immediate cause of death was determined to be systemic inflammatory response syndrome.

  • 멸종위기종의 서식지를 효율적으로 관리하기 위해서는 해당 종의 서식 가능한 지역의 분포를 알아야 한다. 본 연구의 목적은 GIS와 퍼지집합을 이용하여 산양(Nemorhaedus caudatus)의 서식지적합성모형을 개발하여 멸종 위기종의 서식지를 관리하기 위한 정보를 제공하는 것이다. 산양의 서식지적합성모형 개발을 위한 본 연구의 주요내용은 다음과 같다. 첫째, 산양 서식지 이용에 관한 기존 연구를 바탕으로 산양의 잠재적 서식지 환경변수를 분류하였으며, 분석 대상지의 산양 흔적 조사를 통해 서식지 환경변수의 재분류 및 x²검정(Chi-square test)을 통한 변수들의 유용성을 파악하고, 쌍체비교를 통한 환경변수별 가중치를 계산하였다. 둘째, 기존 부울논리(boolean logic)의 단점을 보완하기 위해 현장 조사의 결과를 바탕으로 퍼지논리(fuzzy logic)에 의한 산양 서식지의 각 환경변수별 주제도를 작성하고, 주제도들의 상관관계를 분석하여 상호 관련성이 높은 변수들의 중복을 피하였다. 셋째, 환경변수별 주제도와 변수별 가중치를 바탕으로 다기준평가기법(MCE, Multi-Criteria Evaluation)을 이용하여 분석대상지의 산양 서식지적합성모형을 개발하였다. 마지막으로, 개발된 서식지적합성모형의 타당성을 검증하기 위해 분석대상지 외부 지역을 대상으로 검증을 실시하였다. 분석 결과 분석대상지의 분류정확도는 서식가능성 0.5를 기준으로 93.94%의 매우 높은 분류정확도를 나타내었으며, 검증대상지에서는 95.74%의 분류정확도를 나타내어 본 모형의 분류정확도는 일관성이 높은 것으로 판단되었다. 또한 전체 공원구역에서 서식가능성 0.5이상의 면적은 59%를 차지하였다.퇴적이 우세한 것으로 관측되었다.보체계의 구축사업의 시각이 행정정보화, 생활정보화, 산업정보화 등 다양한 분야와 결합하여 보다 큰 시너지 효과와 사용자 중심의 서비스 개선을 창출할 수 있는 기반을 제공할 것을 기대해 본다.. 이상의 결과를 종합해볼 때, ${\beta}$-glucan은 고용량일 때 직접적으로 또는 $IFN-{\gamma}$ 존재시에는 저용량에서도 복강 큰 포식세로를 활성화시킬 뿐 아니라, 탐식효율도 높임으로써 면역기능을 증진 시키는 것으로 나타났고, 그 효과는 crude ${\beta}$-glucan의 추출조건에 따라 달라지는 것을 알 수 있었다.eveloped.

  • 비무장지대(DMZ)를 포함한 민통선 일대는 지난 50여 년간 사람에 의한 인위적인 간섭을 적게 받은 지역으로 자연생태계가 잘 보전된 세계적인 환경보전지역이다. 그러나 최근 들어 개발에 따른 급격한 환경파괴가 가속화되고 있어 이에 대한 대비가 시급한 실정이다. 현재까지 발표된 조사지역에 대한 논문, 보고서 등 문헌자료와 청문조사를 토대로 조사된 포유동물상을 파악하였다. DMZ 및 군사접경지역 전체에서 서식하는 포유동물 중 문헌상으로 서식이 확인된 종은 모두 6목 17과 51종으로 조사되었으며, 이중 화천군, 철원군, 양구군 일대 중부지역에는 총 6목 14과 32종이 서식하는 것으로 조사되었다. 천연기념물로 지정된 종은 반달가슴곰(Ursus thibetanus), 수달(Lutra lutra), 사향노루(Moschus moschiferus), 산양(Nemorhaedus caudatus), 하늘다람쥐(Pteromys volans), 물범(Phoca largha)등 3목 6과 6종이었다. 이 조사를 통해 얻어진 종합적인 자연문화재 기초자원 조사결과는 향후, UNESCO의 세계자연보전지역 등록에 대비한 기초자료로 활용될 수 있을 것으로 판단된다.

  • The purpose of this study are to compare existing presence-absence predictive models and to predict suitable habitat for Goral (Nemorhaedus caudatus raddeanus) that is an endangered and protected species in Seoraksan national park using the best model among existing predictive models. The methods of this study are as follows. First, 375 location data and 9 environmental data layers were implemented to build a model. Secondly, 4 existing presence-absence models : Generalized Linear Model (GLM), Generalized Addictive Model (GAM), Classification and Regression Tree (CART), and Artificial Neural Network (ANN) were tested to predict the Goal habitat. Thirdly, ROC (Receiver Operating Characteristic) and Kappa statistics were used to calculate a model performance. Lastly, we verified models and created habitat suitability maps. The ROC AUC (Area Under the Curve) and Kappa values were 0.697/0.266 (GLM), 0.729/0.313 (GAM), 0.776/0.453 (CART), and 0.858/0.559 (ANN). Therefore, ANN was selected as the best model among 4 models. The models showed that elevation, slope, and distance to stream were the significant factors for Goal habitat. The ratio of predicted area of ANN using a threshold was 31.29%, but the area decreased when human effect was considered. We need to investigate the difference of various models to build a suitable wildlife habitat model under a given condition.

  • 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.

  • Korean long-tailed goral (Nemorhaedus caudatus) is one of the most endangered species in South Korea. However, detailed species distribution and sex ratio data on the elusive goral are still lacking due to difficulty of identification of the species and sex in the field. The primary aim of this study was to develop an economical PCR-RFLP method to identify species using invasive or non-invasive samples from five Korean ungulates: goral (N. caudatus), roe deer (Capreolus pygargus), feral goat (Capra hircus), water deer (Hydropotes inermis) and musk deer (Moschus moschiferus). The secondary aim was to find more efficient molecular sexing techniques that may be applied to invasive or non-invasive samples of ungulate species. We successfully utilized PCR-RFLP of partial mitochondrial cytochrome b gene (376 bp) for species identification, and sex-specific amplification of ZFX/Y and AMELX/Y genes for sexing. Three species (goral, goat and water deer) showed distinctive band patterns by using three restriction enzymes (Xbal, Stul or Sspl). Three different sexing primer sets (LGL331/335 for ZFX/Y gene; SE47/48 or SE47/53 for AMELX/Y gene) produced sex-specific band patterns in goral, goat and roe deer. Our results suggest that the molecular analyses of non-invasive samples might provide us with potential tools for the further genetic and ecological study of Korean goral and related species.

  • This study was conducted to estimate population size and investigate habitat characteristics for the conservation and management of Amur goral Nemorhaedus caudatus raddeanus in DMZ (Demilitarized Zone) of Gangwon Province in South Korea from November 2003 to May 2004. The Amur gorals counting were carried out by assistance of military soldiers who guards the southern boundary of DMZ. Four hundred sixty individuals were estimated as total population size in DMZ of Gangwon Province. Deciduous forest, rocky area and coniferous forest were dominant land cover types in habitat of Amur goral. DMZ and its vicinity of Gangwon Province are very important areas for the conservation of this species. It is needed to establish management plan for the conservation of Amur goral and their habitats in DMZ.
