목 적 : 태아시기의 장기간 스트레스는 부신의 호르몬 합성에 영향을 미치는 것으로 알려져 있다. 분만 동안의 급성 스트레스와 제대혈 코티솔간의 상관관계를 보고자 본 연구를 시행하였다. 방 법 : 총 58명의 신생아를 대상으로 분만 즉시 제대혈을 10 mL 채취하였고, $4^{\circ}C$에서 2,000 rpm으로 20분간 원심 분리하여 혈청을 분리한 후, 즉시 $-70^{\circ}C$에 냉동 보관하였다. 코티솔의 측정은 Coat-A-Count Cortisol Kit를 사용하여 RIA방법으로 측정하였다. 분만 스트레스와의 관계를 알아보기 위하여 재태 연령(34주 이하, 35-37주, 38주 이상), 분만방식(제왕절개 분만 vs 질식분만), Apgar 점수, 자궁수축 유무 등에 따른 코티솔 농도를 비교하였다. 결 과 : 제대혈 코티솔 농도는 재태 연령에 따라 증가하는 양상을 보였고(P<0.001), 제왕절개 분만 군보다 질식 분만 군에서 코티솔 농도가 통계적으로 유의하게 높았다(P<0.001). 자궁수축을 동반하는 경우가 동반하지 않았던 경우보다 코티솔 농도가 높았으며(P<0.05), 분만 진통시간이 길수록 코티솔 농도가 유의하게 높았다(P<0.05). 코티솔 농도는 1분 Apgar 점수가 낮았을 때 유의하게 낮은 농도를 보였다(P<0.05). 결 론 : 제대혈 코티솔은 분만스트레스와 밀접한 관련성이 있으며, 신생아의 출생 후 예후와도 관련이 있을 것으로 생각된다. Purpose : Long-term stress to the fetus causes alterations in adrenal steroidogenesis. The purpose of this study was to analyze the association of cord blood cortisol with stress during delivery. Methods : Cord blood samples were collected from 58 neonates at once to labor. Cortisol was measured by RIA method(DPC, USA). Cortisol level according to gestational age(<34, 34-37, >38 wks) and method of delivery(Cesarean section vs. vaginal delivery), Apgar score and uterine contraction, were compared to know stress during labor. Results : Cortisol of cord blood had considerable differences between each group, according to gestational age(P<0.001). It was statistically higher in the cases of vaginal delivery than cessarian delivery(P<0.001). The concentration of cortisol was significantly higher according to duration of labor (P<0.05). There was a significant relationship between cortisol level and uterine contraction(P<0.05). The concentration of cortisol was significantly low when Apgar score at 1 min was low(P<0.05). Conclusion : Cord cortisol has close association with stress during labor. And so do with post birth prognosis of neonate.

임현정,이명우,Lim, Hyun-Jeong,Lee, Myung-Woo 한국조경학회 2011 韓國造景學會誌 Vol.39 No.2

본 연구의 목적은 댐 유역 하천코리도 생태경관 구역의 설정과 하천생태계평가를 통해서 생태적 가치가 높은 보전지역을 설정하는데 있다. 본 연구는 2008년에서 2009년까지 수행된 "용담 다목적 댐 및 저수지 주변지역 생태조사"의 일환으로 수행된 연구결과에 기초하였다. 연구대상지역인 용담호는 그 유역면적이 $930km^2$로서 진안, 장수, 무주에 걸쳐 있으며, 주요 유입하천에는 주자천, 정자천, 진안천, 구량천 등이 있다. 이 댐 호는 상수원으로 이용되고 있으나, 유역 내 골프장, 체육공원 등의 난개발이 발생하여 수질오염 및 생태계 훼손이 우려되는 지역이다. 하천코리도의 경관단위구역은 조사 및 도면 정밀도 등을 고려하여 250mm, 500mm, 750mm의 3단계 세부구역으로 구분하였다. 하천생태계 평가는 하천환경평가와 코리도권 식생환경평가의 2가지로 구분하였다. 하천환경평가에서는 어류 및 저서 생물의 종다양성과 고유화 빈도, 하천환경의 자연도 평가를 수행하였다. 식생환경평가에는 임상도, 식생보전등급, 조류 및 포유류의 종다양성과 법정 보호종의 유무 등에 대해서 평가하였다. 각각의 생태공간정보를 그 중요도에 따라 3등급화하였고, 최종적으로 이를 중첩하여 보전우선가치가 높은 지역을 설정하였다. 법정 보호종 출현지점은 절대보전지역으로 설정하였다. 본 연구는 자연환경지역의 보전가치를 평가하는 댐 유역 하천생태계 평가방법을 제시하여, 개별적 생태조사의 결과를 통합할 수 있는 틀을 제시하였다는데 의의가 있다. 야생동물의 행동권과 계절별 서식환경, 생물종 간 관계 등에 대한 연구와 이를 바탕으로 한 에코톱과의 관련성에 관한 연구가 진행되어야 할 것으로 판단한다. The purpose of this study is to specify the prior eco-preserve zone by establishing the eco-landscape unit on the stream corridor and evaluating the stream ecosystem in the dam basin. The fundamental ecological data was surveyed and collected through "the ecosystem project on Yongdam multipurpose dam watershed" from 2008 to 2009. The Yongdam Dam Watershed has several streams, Jujacheon, Jeongjacheon and Guryangcheon, of which the area is $930km^2$, stretching to Jinangun, Jangsugun and Mujugun Jellabukdo. In spite of being used for drinking purpose, the dam water quality and ecosystem is threatened by in-watershed pollution produced by development, golf course grounds and sports complex, etc. The landscape unit of stream corridor was zoned across by 250m, 500m, and 750m from the vicinity line of stream, which was decided to the accuracy of mapping and surveying. Types of evaluation are the Stream Corridor Evaluation(SCE) and the Vegetated Area Evaluation(VAE). In the process of SCE, several indices were analysed, fish species diversity, species peculiarity, and stream naturality. Indices for VAE were forest stand map, vegetation protection grade, species diversity and peculiarity for wild bird and mammal life. The importance of the ecological items is categorized into three levels and overlapped for specifying the prior preserve zone. The area at which legally protecting species appeared is categorized as absolute preserve area. This study might be meaningful for proposing the evaluation process of a stream corridor ecosystem, which can synthesize a lot of individual ecological surveys. We hope further research will be actively performed about the ecotope mapping which is based on a individual wildlife territory and habitats and also their relationships.

This study aims to present primary data for habitat restoration and artificial breeding conditions of L. unmunsana by identifying the habitat conditions and the larvae's food sources. In order to investigate the habitat characteristics of the adult L. unmunsana and land snails, which are the primary food sources for the larvae, field surveys were conducted on a total of 10 habitats in south-central parts of Korea including Sanseongcheon, Jeonju. The results revealed that the L. unmunsana habitat in the Sanseongcheon area had a broadleaf forest with a multi-layered vegetation structure, adjacent water features, and the north/northeast/northwest slopes with little effect of artificial lighting. The adult L. unmunsana in the Sanseongcheon area appeared from the end of May to the end of June, and was especially intensively observed around the middle of June. The most active time was from 23:30 to 00:30 with a temperature range of 19~22℃ and higher than 80% humidity. The peak count of the observed adults L. unmunsana was a total of 774 on June 11, 2021. In the case of land snails, 11 families and 23 species were observed in 10 habitats of L. unmunsana, and Euphaedusa fusaniana was the most extensive and the most observed in the five survey areas. The land snails of L. unmunsana habitats are mostly found under the organic layers of leaves and a fallen tree branch in broadleaf forests, where a thick organic material layer buffers temperature changes and provides high humidity for various snails. These habitat conditions are suitable for the larva of L. unmunsana and land snails to inhabit, feed, hide and hibernate.

A significant production decrease has been witnessed for the Pacific oysters, Crassostrea gigas farmed in the western coastal waters of Korea, presumably by the loss of physiological viability. We evaluated the viability in terms of health indicators, the condition indices and hemocyte apoptosis rates of the oysters inhabiting two representative farming sites, Incheon and Taean each with different environmental variables. In our monthly measurements for the whole year 2013, the indicators were location specific. The condition indices of Incheon were highly variable, 1.67-8.58%, while those of Taean were less, 2.28-5.57%. The condition indices decreased during the spawning seasons, July and September in common. The two oysters exhibited also differed in the apoptotic activities of hemocyte, highly active, 4.03-30.15% for Incheon oysters and less active, 2.87-17.48% for Taean oysters. One thing we could identify was the two measurements were adverse during the critical seasons of spawning, reminiscent of being a useful tool for a health indicator for the oysters. Similar trend was also observed in the time when change in temperature was extreme. The findings in this study are highly indicative of health indicators for the oyster aquaculture.

Vegetable soup has been reported to have anti-inflammatory, anti-oxidative and anti-cancer effects. In this study, five kinds of vegetable soup were developed using a new manufacturing process and compositional changes in raw material, and anti-cancer and immuno-stimulatory activities were evaluated. Cytotoxicity tests based on MTT assay revealed that all vegetable soups had strong inhibitory effects against CT26 mouse colon cancer cells, with soups including Solomon's seal being most effective based on comparison of $IC_{50}$ values. Apoptosis in response to vegetable soup was occurred by 3-5 fold on cancer cells compared to normal cells. Mouse splenocytes increased by 266-541% in response to addition of vegetable soup in an in vitro proliferation experiment. In co-culture with splenocytes and CT26 cancer cells, splenocytes increased by more than 280% in every vegetable soup treatment, while cancer cells decreased by about 60% and cytokines such as $IFN- {\gamma}$ and IL-12 were secreted from splenocytes in high levels only in response to vegetable soup including Solomon's seal. In conclusion, all vegetable soups developed in this study had anti-cancer effects, and vegetable soup including Solomon's seal showed the strongest anti-cancer and immuno-stimulatory effects. These results suggest that functionality of vegetable soup could be increased by changes in manufacturing processes and raw materials composition.

임현정 ( Hyun Jung Lim ),전재헌 ( Jae Hun Jun ),이재철 ( Jae Chul Lee ),김병수 ( Byung Soo Kim ),이원주 ( Weon Ju Lee ),이석종 ( Seok Jong Lee ),김도원 ( Do Won Kim ),정호윤 ( Ho Yun Chung ),배한익 ( Han Ik Bae ),이종민 ( Jong Min 대한피부과학회 2010 대한피부과학회지 Vol.48 No.3

Glomuvenous malformation (GVM), an uncommon variant of venous malformation (VM), reveals dilated venous channels lined by variable amounts of glomus cells histopathologically. It appears as compressible blue or blue-purple nodules or plaque(s), sometimes showing a familial tendency. GVM usually involves only the superficial layer of the cutis or subcutaneous tissue, unlike VM, which frequently involves deeper tissue. Although GVM shares features of VM and glomus tumor, their clinicopathological and/or genetic features are sufficiently distinctive to enable a differential diagnosis, which is important for management decisions. Herein, we report five patients who showed a large confluent patch or several scattered patches composed of tender bluish blebs. Two patients among them were siblings. Histopathological and immunohistochemical examinations confirmed GVM. (Korean J Dermatol 2010;48(3):220~227)
