This study was conducted to obtain the basic research about Siberian roe deer (Capreolus pygargus), and to establish a conservation area into Seoraksan(Mt.) National Park, South Korea. We recorded Siberian roe deer field signs (bedding sites, feeding areas, feces and tracks etc), and habitat variables such as nearest distance to the watercourse, trails, slope, aspect, forest type and land cover etc. from Jan. 2006 to Dec. 2007 in Seoraksan(Mt.) National Park. According to the research of habitat characteristics of Siberian roe deer inhabited in Seoraksan(Mt.) National Park preferred mixed forest consisted of aged forest and middle-aged forest on the gentle slope which was close to hydrosphere in the middle elevation area of altitude of 400~600m above sea level in Seoraksan(Mt.) National Park. The results indicated that Siberian roe deer appeared to prefer south slope or north slope during the snow season and west or east slope during the non-snow season. The area of most suitable habitat for Siberian roe deer in Seoraksan(Mt.) National Park was 125.8km2 (32% of the total area) followed by 244.3km2 buffer area (62.2% of the total area), and 22.9km2 unsuitable habitat area (5.8% of the total area), which means environmentally unsuitable habitat for Siberian roe deer was rare in Seoraksan(Mt.) National Park. Thus, the area classified as major area in Seoraksan(Mt.) National Park appeared to be most important for the protection of Siberian roe deer.

본 연구에서는 삼차원 수치모형을 사용하여 하천 하상에 설치된 보 주위의 흐름특성을 수치모의 하고 이를 비교 분석하였다. 이를 위한 보 주위 수치모의 롤 통해 월류 조건에 따른 최대 유속분포와 유속 벡터 변화가 분석되었다. 사용된 삼차원 흐름 모의 수치모형은 보 주위 흐름의 유속분포를 잘 모의하였으며, 분석결과 적용된 일반형, 계단형, 오지형, 경사형의 4가지 유형 중 수치해석 결과에서는 월류 능력 등을 고려할 때 오지형이 가장 적합한 구조인 것으로 검토되었다. This paper presents a numerical study for the flow characteristics around weir in the river bed by using the three-dimensional model. In this study, we compared the maximum flow velocity and velocity vector by overflow condition of weir, with those measured in the simulations with a channel model. Three-dimensional model provides for a quite accurate prediction of flow and bed variation for the flow characteristics around weir. As a result of the numeric methods among the applied 4 weir types, the wedge type was reviewed as the most appropriate structure regarding the overflow discharge ability.

A total of 423 shellfish (Oysters, Crassostrea gigas; short-necked clams, Ruditapes philippinarum and corb shells, Cyclina sinensis) were collected from the west coast of Korea, from which 277 Escherichia coli strains were isolated. The antimicrobial susceptibility patterns of isolated strains were analyzed for 22 antimicrobial agents used in Korea for clinical or veterinary therapy. The resistance of E. coli isolates to ampicillin (37.2%) was highest, followed by cephalothin (21.7%), cefazolin (19.9%), trimethoprim (15.2%). Antimicrobial resistance was present in 56.7% of E. coli isolates against at least one antimicrobial agent. Of 277 isolates, 44 (15.9%) were resistant to multiple antimicrobial agents.

This research was completed to provide fundamental data regarding the guidelines to installing and managing utility facilities & structures in wetland protected area to advance the functions and sustainable use of ecology services by preserving the ecology within wetland protected area. There were 5 on-site researching areas that were used as the main subject with these areas chosen and considered from 21 inland wetlands that have been designated and are being managed from the Ministry of Environment and by their designated dates as a wetland protected area. The utility facilities in these wetland areas were categorized by their types and a detailed on-site investigation was proceeded with investigation items chosen whereas these facilities are working by their roles from their location, size, used materials, types, information contents and etc., The results showed that regarding informational structures, several locations of information boards were distanced from the main exploring routes which did not consider the visitor``s eye level which had their readability dropped and by sunlight, time lapse and water penetration, many information boards were damaged or corrupted so that it was hard to confirm the information noticed or understanding an image. Insufficient observation and educational structures were installed that considered the ecological characteristics of wild animals and their living conditions. Regarding convenience facilities, there were parking lots that were installed on the fore-land and to decrease non-point solution sources, some parking lots needed to be located in protected lowlands while some facilities`` shape and colors did not harmonize with their natural surroundings, creating a sense of awareness, which will need some more consideration. As for safety facilities, they were very insufficient compared to other facilities. This means that additional safety structures areneeded so that related personnel can be aware of where a visitor is located when an accident occurs. Protectional facilities strongly needed new structures and a management system to cut off entrances and do surveillance so that visitors do not go into areas outside of the managed areas and bring damages to restricted locations. Research labs needed to expand the use of automatic weather systems and water gauge equipments to build fundamental data regarding floodgates that are intimated to the forming of wetlands. Sensor cameras and other types of monitoring systems are needed to monitor the majority types of animals living in the wetlands as well.

Noroviruses (NoV) are known to cause acute epidemic gastroenteritis worldwide. Outbreak strains are predominantly genogroup I (GI) and genogroup II (GII) in oysters Crassostrea gigas. We investigated the changes in concentration of male specific coliphage (MSC) and NoV under heat treatment of the naturally contaminated oyster, Crassostrea gigas. After heat treatment for 5 min in 85℃, no viable MSC was detected. The concentrations of GI and GII NoV decreased by 1.65 log and 2.25 log, respectively, following heat treatment for 5 min at 100℃. Moreover, both GI and GII NoV were completely deactivated by heat treatment for 10 min at 100℃. Therefore, in order to reduce the risk of norovirus infection from contaminated oysters, immersion in boiling water for at least 10 min is recommended.

This study aimed to develop the HSI (Habitat Suitability Index) model of Cypripedium guttatum. and to verify this model by applying to the candidate sites for replacement habitat. The development of HSI and SI (Suitability Index) model was conducted based on the existing literature, field surveys, and expert opinions for information on ecological habitat characteristics. Seven variables were selected as habitat variables including mean maximum temperature in Jul.-Aug., lighting, slope, altitude, effective soil depth, soil texture, and artificial overexploitation (i.e. protected areas). HSI model was developed for C. guttaum based on these variables. This HSI model showed high applicability to selection and evaluation of replacement habitats for C. guttaum. Our findings could provide the basic information on habitat assessment to prevent the extinction of endangered C. guttatum. However, since there is a limitation that the survey data were insufficient, further field surveys should be conducted on several habitat types to improve the accuracy of the HSI model.
