We surveyed mammalian roadkill at the National Route 6 (Jin-gogae to Songcheon, 18㎞) and a local road 446 (Odaesan National Park office to Sangwon-temple, 12㎞) in Odaesan National Park. Data of the surveys were analyzed by year, month, and species. Roadkills of 226 individuals were found at the survey areas. Of them, the road-killed 131 mammal individuals, 44 bird individuals, 40 reptile individual and 11 amphibian individuals were found during the survey period. High ratio of the road-kills was observed in mammals than the other animals. Among mammalian species, high ratio of the road-kills was observed in squirrels. There were road-kills of three endangered species, containing otters, yellow-throated marten and leopard cats. According to the analyses of annual road-kills, roadkills of 104 cases were occurred and highly frequent in 2014, following by roadkills of 81 cases in 2015, and then those of 41 cases in 2016. Most ases of the roadkills occurred in summer (June to September). The results will contribute to establishing management for reduction of roadkill in Odaesan National Park.

본 연구는 산악환경의 기상 특징과 계룡산국립공원 탐방로의 열쾌적성을 파악하고 열쾌적성이 높은 활동 시간 정보, 활동 공간 정보, 활동량 정보를 제공하기 위해 시행되었다. 탐방로의 열쾌적성 분석을 위해 여름철 도심 기온, 국립공원 방재기상관측장비(AWS, Automatic Weather System), 탐방로인 숲길의 평균 기온을 비교하였다. 또한, 계룡산 국립공원의 주요 탐방로 4개 구간의 미기후 요소와 수관울폐도 측정을 위해 총 240개 지점을 조사 후 열쾌적성을 파악 하였다. 도심과 국립공원AWS, 탐방로의 평균 기온을 비교하였을 때, 도심, 갑사AWS, 동학사AWS, 갑사 탐방로, 동학사 탐방로 순으로 평균 기온이 높게 나타났다. 이 결과, 탐방객이 직접 체감하는 탐방로의 열쾌적성을 고려해야 함을 의미한다. 주요 탐방로 4개 구간 조사 결과, 평균 수관울폐도는 동학사~남매탑 구간, 동학사~관음봉 구간, 갑사~연천봉 구간, 갑사~금잔디고개 구간 순으로 높았다. PMV(예상평균온열감)는 활동량이 2.8MET 일 때, 갑사~금잔디고개 구간, 갑사~연천봉 구간, 동학사~남매탑, 동학사~관음봉구간 순으로 높았다. 조사를 통하여, 열쾌적성이 높은 시간 정보, 공간 정보, 활동량 정보를 제시할 수 있었다. 탐방로의 열쾌적성 특성을 파악하여, 탐방로의 어메니티를 높일 수 있는 숲길 관리 방안의 기초를 마련하고자 한다. This study was conducted to understand the weather characteristics of the mountain environment and the thermal comfort of Gyeryongsan National Park trail and to provide information on activity time, activity space, and activity amount. For the analysis of the thermal comfort of the trail, the temperature of the city center in summer, the average temperature of the National Park Disaster Prevention Weather System (AWS), and the trail. Also, Microclimate elements and canopy closure were also measured in four major trails in Gyeryongsan National Park. After investigating a total of 240 points, thermal comfort was identified. When comparing the average temperature of the city center, National Park AWS, and trail, the average temperature was higher in the order of the city center, Gabsa AWS, Donghaksa AWS, Gabsa Trail, and Donghaksa Trail. As a result, it means that the thermal pleasure experienced by visitors should be considered. According to a survey of four major trails, the average canopy closure is Donghaksa~nammaetop route was high in the order of Donghaksa~Gwaneumbong route, Gabsa~Yeoncheonbong route and Gabsa~Geumjandigogae route. When PMV(Predicted Mean Vote) is 2.8MET, The PMV was highter in the order of Gabsa~Geumjandigogae route, Gabsa~ Yeoncheonbong route, Donghaksa~nammaetop route, Donghaksa~Gwaneumbong route. Through the survey, time information, spatial information, and activity information with high thermal comfort could be presented. By grasping the thermal comfort characteristics of the trail, we intend to lay the foundation for forest trail management measures that can increase the amenity of the trail.

We investigated species, ecological pathway type, and mammal size using two eco-tunnels from trail-camera data. The analyses of the camera data showed that 12 mammalian species from 8 families of 5 orders used Jin-gogae eco-corridor (bridge type) and 14 mammalian species from 9 family 5 orders were found at Odaesan eco-corridor (tunnel type). At both eco-corridors, water deer used eco-corridor most frequently, and then secondly racoon dog did. The analyses by mammal size (small, medium, and large) showed that large-sized mammals were found in high ratio at the bridge type of the eco-corridors. In case of medium-sized mammals, utilization ratio of the tunnel-typed corridor was 42%, whereas that of the bridge-typed corridor was 24%, showing 1.8 times higher usage.

박기현,전효진 啓明大學校 醫科大學 1995 계명의대학술지 Vol.14 No.4
It has been understand that a laboratory information system(LIS) plays an important role in a hospital information system(HIS). However, few HIS has been equipped with a fully automated LIS. This is partly because, in order to achieve a fully automated LIS, there are many testing equipment has its own communication protocol. In this paper, a bi-directional communication system between an ABBOTT SPECTRUM EPx auto-chemical analyzer and a PC is constructed. With the communication system, it is possible that a PC controls an EPx's operations and that the PC receives test results form the EPx automatically. RS-232C serial ports are used in order to make bi-directional communication possible between them

박미소,윤효진 경기대학교 산업기술종합연구소 2006 산업기술종합연구소 논문집 Vol.31 No.-
일반적으로 교통사고의 원인을 자동차, 운전자, 도로교통환경등의 세 가지 삼각구도로 규명하지만, 교통사고의 직접적인 원인은 교통행동에 의해 결정되어진다고 할 수 있다. 따라서 본 논문에서는 사고원인의 물리적 요소 외에도 인간행동을 결정짓는 요인들을 통해 행동결함들을 분석하여 결함에 대한 대책을 세울 수 있는 방법을 제시하고자 하는 것이다. 결함요인들에 대한 분석을 통해서 특히, 지각·운동요인과 성격요인의 요소들을 통해 결함의 순위를 결정해 보고자 한다. 그리고 이러한 결함을 어떻게 대처해야 할지 운전 재설계의 원칙을 제고해 보는데 그 의의를 두고 있다. 교통과 관련된 일을 하고 있는 일반인들보다는 다소 많은 지식, 정보 그리고 경험을 가지고 있는 전문가들을 대상으로 여러 가지 상세한 설문을 통해서 결함요소와 교통사고, 결함요소간의 상관관계를 분석하여 각 요소에 대한 가중치를 결정하고 다시 이것을 주관성의 일정 부분 배제를 위해 일반화 시켜 그 가중치에 따른 결함 점수의 합계를 구해 어떤 결함이 얼마나 많은 문제점이 있는지 분석하였다. 그리고 최종 결함 점수가 가장 높은 결함을 선정하여 제시된 재설계 원칙에 따라서 운전 행동결함을 수정할 수 있는 정보를 얻고 스스로의 운전 단점을 보완하는데 필요한 자료의 가이드라인으로 활용할 수 있다.
Inhibitory Effect of Cordycepin on Human Platelet Aggregation
박화진,--,--,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.1
Cordycepin separated from Cordyceps militaris is a major physiologic active component in Cordyceps militaris. The platelet aggregation is stimulated by Ca^(2+), which is either mobilized from intracellular endoplasmic reticulum or transported from extracellular space. cGMP antagonizes the actions of Ca^(2+). Based on these facts, we have investigated the effects of cordycepin on the mobilization of Ca^(2+) and the production of cGMP on collagen (10 ㎍/ml)-induced human platelet aggregation. Cordycepin potently stimulated the human platelet aggregation induced by collagen (10 ㎍/ml) in a dose-dependent manner. Cordycepin (500 μM) inhibited also the collagen-induced human platelet aggregation in the presence both 1 mM and 2 mM of CaCl_(2). These are in accord with the results that cordycepin inhibited the Ca^(2+)-influx on collagen-induced human platelet aggregation. These results suggest that cordycepin decrease the intracellular Ca^(2+) concentration to inhibit collagen-induced human platelet aggregation. Besides, cordycepin increased the level of cGMP on collagen-induced human platelet aggregation. This result is related with the decrease of intracellular Ca^(2+) concentration, because cGMP inhibits the mobilization of Ca^(2+). In addition, cordycepin inhibited the human platelet aggregation induced by LY-83583, inhibitor of guanylate cyclase. This result suggested that cordycepin inhibit the platelet aggregation by stimulating the activity of guanylate cyclase. In conclusion, we demonstrated that cordycepin might have the antiplatelet function by inhibiting Ca^(2+)-mobilization via the stimulation of the production of cGMP.

최근 가장 각광받고 있는 컴퓨터 분야 중 하나가 가상현실 기술이다. 가상현실 기술은 기존의 정보 제공 방식 및 상호작용 방식으로는 제공하기 어려운 생생한 지식과 체험을 다양한 매체를 이용하여 가능하게 할 수 있기 때문에 다양한 분야에서 활용되고 있다. 특히, 교육 분야에서 가상현실은 학생들에게 훨씬 더 효과적인 교육과 함께 실제 실험을 하기에 어려운 부분들도 가상으로 구현할 수 있게 해준다. 본 논문에서는 가상현실을 기반으로 하는 컴퓨터 조립과정 학습 시스템을 구현하였다. 컴퓨터 조립과정을 교육하는 데 있어서는 실습이 가장 중요하다. 그러나 기존의 자료들은 과정을 설명한 텍스트나, 2차원 이미지 데이터를 사용하고 있어 그저 보여주는 학습에 그치고 있다. 이런 단점을 보완하기에는 가상현실을 이용한 학습이 가장 좋은 대안일 것이다. 본 논문은 VRML과 EAI를 이용한 Java를 사용하여 시스템을 구현하였다. 이는 학습자들에게 좀더 현실감있는 교육환경을 제시해 주어서 학습효과를 극대화시킬 수 있다. This paper is organized as explanation and implementation of computer assembling process study system based on virtual reality. The proposed system is implemented in VRML(Virtual Reality Modeling Languge) and Java using EAI(Extemal Authoring Interface) in order to provide more realistic and more dynamic materialization than any other Web sites. This system provides three-dimensional infor malions, so it gives the students special experience in loaming computer architecture and computer assembling process.
