이 연구의 주된 목적은 구례 농촌지역에 서식하는 1쌍의 너구리(Nyctereutes procyonoides koreensis) 행동권을 측정하고 이전 너구리 연구와 비교하는데 있다. 원격무선추적은 2개체의 너구리를 이용하여 2개월 간격(2000년 6, 8, 10, 12월)으로 2일씩 주기적으로 수행되었다. 모니터링 기간 동안, 무선추적은 주간과 야간에 걸쳐 보통 1~3시간 간격으로 실시되었다. 전체 46~64개의 무선추적 자료의 분석 결과는 95% 최소볼록다각형(MCP) 방법에서 1쌍의 너구리의 전체행동권 크기가 1.41㎢, 평균행동권 크기가 0.32㎢임을 보여주었다. 암컷과 수컷의 행동권은 상당 부분 중첩되었고(약 70~95%), 행동권 크기는 서로 유사한 양상을 나타내었다. 그러나 주간(0.01㎢)과 야간(0.35㎢)의 행동권 크기는 매우 큰 차이를 보였고, 여름(0.56㎢)에 가장 컸지만 겨울(<0.01㎢)에 가장 작았다. 추가적으로, 1쌍의 너구리는 1개의 핵심지역과 4개의 서로 다른 섭식지역들을 가지고 있었다. 결론적으로, 동일한 개체들을 이용하여 하루 동안 더 빈번한 추적 수와 더 긴 추적 간격을 이용한 이 너구리 행동권 자료는 하루 동안 덜 빈번한 추적 수와 더 짧은 추적 간격을 이용한 이전의 연구와 매우 유사한 결과를 보여 주었다. The primary aim of this study is to estimate the home range of a pair of raccoon dogs(Nyctereutes procyonoides koreensis) and to compare with the previous study of raccoon dogs in a rural area of Gurye, the southern part of South Korea. Radiotracking was regularly carried out on 2 raccoon dogs for 2 days every 2 months(in June, August, October and December, 2006). During the 2 days, radiotracking was usually conducted every 1~3 hours through day and night. The analysis of tracking data with a total of 46~64 bearings showed that the total home range size of the pair was 0.41㎢, and mean home range size was 0.32㎢ by 95% minimum convex polygons(MCP) estimate. The home ranges of the male and female were largely overlapping(about 70~ 95%), and the sizes were not very much different from each other. However, there was a big difference between day(0.01㎢) and night-time(0.35㎢) home ranges, and it was largest in summer(0.56㎢) and smallest in winter(<0.01㎢). In addition, the home range of the pair included 1 core area and 4 different feeding areas. In conclusion, our raccoon dog home range data using the same individuals but with more frequent bearings per day and more extended tracking intervals still showed very similar results to the previous study with less frequent bearings per day and more extensive tracking days.

The space of public libraries has been changed in the direction of supporting user satisfaction and various activities, focusing on the role of data preservation and education. However, unlike before, the use of space is not suitable to accommodate various needs, such as the disappearance or reduction of existing space to provide services and programs. In particular, a method of calculating the size according to the number of people within a certain range or calculating the size by referring to the average size of other nearby libraries was proposed. In this study, factors influencing the number of users were derived through the analysis of previous studies. The factors derived from previous studies are limited to the physical factors necessary to calculate the size at the pre-planning stage, so the influencing factors were supplemented and added to four categories: education, culture, commerce, and transportation facilities. As of 2019, statistical data from 33 public libraries in Busan were analyzed to collect data within 0-1km walking distance, and hierarchies were classified according to the number of visitors by region to derive influencing factors that affect visitors regardless of size. The analysis method was conducted in two ways through impact analysis and regression analysis according to the visitors award/middle/lower hierarchy. As a result of the study, factors influencing high school libraries such as the number of high school students, parks, and movie theaters were derived. Through the results of these studies, it is expected that a hypothesis can be established based on the physical factors of the Busan Library and used to establish a calculation formula for calculating the size of the public library in the future.

The terrestrial leeches from the peripheral island of the Korean Peninsula were identified as Haemadipsa rjukjuana Oka, 1910. The arhynchobdellid family Haemadipsidae and H. rjukjuana are newly added into the Korean leech fauna. This species is blood-feeding leech that attacks birds and medium or large sized mammals primarily, including human. The sequence of mitochondrial cytochrome c subunit I (COI), and the additional biology for this species are presented. This is the first study of terrestrial blood-feeding leeches in Korea.

이 연구의 목적은 고라니(Hydropotes inermis argyropus)의 위내용물을 대상으로 PCR-DGGE 방법을 이용하여 그 식이습성을 조사하는데 있다. 이 연구를 위해, 강원도 철원과 전라남도 동부지역 등에서 자연사 혹은 로드킬에 의해 죽은 고라니 사체의 위에서 식이물 샘플을 채취하였다. 총 44개체의 위내용물에서 각각 DNA를 추출하였고, 두 가지의 프라이머(rbcLZ1과 rbcL19bR)를 이용하여 ribulose-1,5-bisphosphate carboxylase large subunit(rbcL) gene을 PCR 증폭하였다. 44개의 샘플 중 29 샘플에서 성공적으로 PCR을 수행하였다. 이 29개 partial rbcL gene의 PCR product는 PCR-DGGE에 이용되었다. 식이물에 대한 분석결과 총 6과의 식물이 확인되었다. 강원도 철원의 경우, 5과가 나타난 반면, 전라남도 동부의 경우, 3과만이 확인되었다. 이 연구에서는 종수준의 먹이식물의 구별에는 실패하였지만, 차후 이 PCR-DGGE 기법은 고라니를 포함한 초식동물의 식이습성을 분석하는데 하나의 가능성 있는 방법이 될 것으로 생각된다. The aim of this study is to examine feeding habits of the Korean water deer(Hydropotes inermis argyropus) from its rumen contents using a PCR-DGGE method. For this study, rumen contents were collected from water deer causalities by natural death or road-kill in two different sites(Cheorwon, Gangwon province and the Eastern part of Jeonnam province). DNA was extracted from rumen contents of a total of 44 individuals. Two primers, rbcLZ1aF(GC) and rbcL19bR, were used for PCR amplifications of ribulose-1,5-bisphosphate carboxylase large subunit (rbcL) gene. Among 44 samples, twenty-nine samples were successfully amplified by PCRs. The 29 PCR products of partial rbcL gene were applied for PCR-DGGE. Totally, six families of plants were detected from the diet analyses. Five families of plants were found in Cheorwon, Gangwon province, but only three families of plants were found in the Eastern part of Jeonnam province. The PCR-DGGE method will provide us with a potential tool to study feeding habits of ungulates including water deer, even though our results failed to identify the prey plants at the level of species.
