In order to determine whether vegetation would be one of the factors for the selection of otter home range, vegetation structure and other potential factors were studied in Hwacheon, Korea. Thirteen sites, otter’s activity found and not found, were investigated in North Han River and connected tributary streams of Hwacheon-gun. Three types of vegetation were classified by cluster analysis, which is short grass, tall grass and shrub type. Vegetation zone of each channel is composed of either one type, or mosaic of tall grass and shrub type. Short grass type is common in Lake Paro and upper North Han-river where water level is highly variable throughout a year. Therefore, annual species such as Persicaria nodosa, Fimbristylis dichotomam and Chenopodium ficifolium are the most dominant. Shrub type is common at the downstream sites of Jichon stream and along mainstream of North Han River down Lake Paro. A shrub species, Salix koreensis, is the most common. Tall grass type is dominant occupying the most vegetation zone of the tributary channels. Phragmites japonica is absolutely dominant. Due to its dense cover, a few plant species are co-existed. Otter activity was found in all three vegetation types and no marked activity was found at some sites of tall grass type. There is no difference in species composition and physiognomy between tall grass sites with and without otter activity, while it shows significant difference in fish availability between two groups. Overall we found that home range of otters in the region is along the mainstream and downstream of tributary streams with high fish availability in all vegetation types and in various human activity levels.

Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

한현정,전은경 울산대학교 2005 생활과학논문집 Vol.7 No.1

본 연구의 목적은 현대여성의 구두 착용에 따른 발 및 주변 부위의 문제점을 밝히는데 있다. 본 연구에서는 주된 구두 소비자 계층인 20대 여성들을 대상으로 소비자 설문조사를 통하여 구두 착용현황 및 그에 따른 발 장애를 살펴보고 구두 제작시 필요한 기초자료를 제공하고자 하였다. 본 연구의 결과를 살펴보면, 구두 착용여성의 대부분이 연령과 착용시간에 관계없이 많은 장애를 경험하였다. 그러므로 구두장애 요인 중 가장 많이 지적된 ‘구두골 치수’와 소재의 개선이 요구된다. 특히, 발둘레 치수에 대해서는 소비자와 판매자의 인지도가 약해 적절히 사용되지 못하고 있으므로 KS 규격에 대한 홍보가 필요하다. The purpose of this study was to identify the problems of women’s feet and it’s relative area caused by wearing shoes. This study was conducted through a survey with 384 young women consumers of 20s. Most respondents indicated that problems while wearing shoes. The reasons of the discomfort were ‘unfit of the size’ and ‘inappropriate materials.’ Most respondents were found to have the knowledge of their sizes but not of the letter sizes for the foot girth. Seventy six percent indicated that they of the respondents rarely know about the letter size. Most of the respondents (92.5%) indicated that they never checked the letter size when purchased shoes. This implicates that consumer education concerning the ‘KS G 3405 Lasts for shoes’ size system is necessary.
