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.

본 연구의 목적은 우수 테니스 선수들의 경기력에 영향을 미치는 스트레스 요인들을 규명하고 그 요인에 대해 그들이 활용하고 있는 대처방안을 규명하는데 있다. 본 연구에서는 전, 현직 국가대표 테니스 선수 15명을 대상으로 스트레스 요인과 대처방안을 내용 분석한 결과 5가지 스트레스 요인과 19가지 대처방안이 도출되었다. 스트레스 요인들로는 심리적 요인, 상대적 요인, 신체적 요인, 시합상황 요인, 그리고 팀 요인의 순으로 나타났다. 5가지 요인 중 세부적 요인으로 불안, 자신감 결여, 승리에 대한 압박감, 상대선수에게 지고 있을 때 선수들이 대부분 스트레스를 겪고 있는 것으로 확인되었고, 시합에 미치는 정도에서는 훈련부족과 슬럼프 요인이 가장 영향을 많이 미치는 것으로 나타났다. 대처방안으로는 심리적 요인에는 자신감, 긍정적사고, 경기를 즐김, 무시, 자아최면/자아대화, 경기집중, 신앙, 대화, 편안한 마음, 훈련/연습, 전술/전략, 승패초월, 목표설정, 페이스 유지, 휴식, 기분전환 방법을 사용하는 것으로 나타났다. 상대적 요인에는 전술/전략, 자신감, 페이스 유지, 자아최면/자아대화, 상황점검, 긍정적사고, 성실한 플레이, 기분전환, 편안한 마음으로 나타났다. 신체적 요인에는 훈련, 자신감, 편안한 마음, 자아최면/자아대화, 전술/전략, 정신력, 페이스 조절, 경기집중, 휴식, 기분전환, 신앙, 긍정적 사고, 영양섭취의 방법을 사용하는 것으로 나타났다. 시합상황 요인에는 심판순응, 긍정적 사고, 경기집중, 편안한 마음, 무시, 경기를 즐김, 기분전환, 자아최면/자아대화의 방법을 사용하는 것으로 나타났다. 팀 요인에는 대화/격려, 전술/전략, 경기집중, 믿음/신뢰, 긍정적사고, 편안한 마음, 무시, 훈련, 파트너교체, 경기를 즐김, 당당함, 약속의 방법을 사용하는 것으로 나타났다. 19가지 대처방안 중에서 엘리트 테니스 선수들이 가장 많이 사용하는 대처방안은 자신감, 전술/전략, 긍정적 사고, 경기집중 등의 순서로 나타났다. 따라서 우리나라 엘리트 테니스 선수들은 많은 스트레스 요인으로 인하여 경기력에 영향을 받고 있고 또한 나름대로의 대처방안을 강구하고 있는 것으로 확인되었다. This investigation examined the sources of stress and coping strategies in Korean elite tennis players. Fifteen tennis players who were former and current national tennis athletes were interviewed about the sources of stress they experienced and coping strategies they used at present and in the past, Qualitative methodology was utilized in this study and five stress sources and nineteen coping strategies were identified. Five stress sources in order were psychological factors (anxiety, confidence, pressure, slump, substitutions, and fear), opponent factors (losing, meeting a strong opponent, and knowing an opponent well), physical factors (injury, condition, and physical fitness), competition factors (judge and broadcasting), and team factors (a coach and senior's punishment, training, and teamwork). Nineteen coping strategies were confidence, tactics/strategies, positive thoughts, game concentration, training, comfortable mind, self-hypnosis/talk, ignore, communication, judge's agreement, fun with game, pray, face control, mood change, mental toughness, situation check, belief, rest, and etc.. The result showed that anxiety and lack of confidence were most frequently experienced stress and confidence. tactics/strategies, positive thoughts, and game concentration were most frequently used coping strategies. Therefore, this investigation confirmed that Korean elite tennis players experienced stress from many factors and used appropriate coping strategies against stress they experienced.

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.

In order to make a functional jam containing garlic, sugar, acid and pectin were mixed with garlic and concentrated by heating the mixture under atmosphere or vacuum conditions. And changes of some physico-chemical properties of the garlic jam(i.e., color, textural properties, vitamin C) were investigated during storage at 30℃. It was found that lightness(L) was higher in sample of vacuum concentration than that in atmosphere concentration and redness(a) and yellowness(b) were higher in sample of atmosphere concentration. During the storage lightness was found to decrease for all samples with more drastic decrease in sample of atmosphere concentration where browning was more severely observed after 8 weeks of storage. In terms of textural properties, hardness, chewiness and gumminess were higher in sample of atmosphere concentration than that in vacuum concentration. And springiness and cohesiveness were higher in sample of vacuum concentration. Although sensory score for garlic jam found to be lower than that for the existing strawberry jam, the present garlic jam might have high marketability if considering its physiological value. 마늘을 이용한 기능성 잼을 제조하기 위하여 마늘에 당, 산, 펙틴을 첨가하고 평압과 감압에서 농축하여 마늘잼을 제조한 후 색도, 조직특성을 조사하고 30℃에서 저장하면서 색도, 조직의 변화, 비타민 C의 변화를 측정한 결과는 다음과 같다. 원료마늘의 일반성분은 수분 57.2%, 탄수화물 23.6%, 조단백 1.9%, 조지방 0.75%, 회분0.93%이었고 비타민 C는 8.4 mg/l00g이었다. 명도는 진공농축한 것이 평압농축한 것보다 높았고 적색도와 황색도는 평압의 것이 높았다. 저장기간에 따라 명도는 모두 감소하였으나 평압에서 농축한 것이 감압보다 크게 감소하였으며 갈변화가 저장 8주에는 심하게 나타났다. 마늘잼의 조직특성은 hardness, chewiness, gumminess는 평압농축이 감압농축에 비하여 높았고 springiness, cohesiveness는 평압농축이 낮았다. 마늘잼의 기호성은 딸기잼에 비하여 떨어지지만 기능성을 감안할 때 시장성이 매우 높을 것으로 판단한다.

본 연구는 정보화근로사업으로 인한 관련산업의 고용유발효과가 어느 정도인가를 알아보기 위해 산업연관분석(I/O) 기법을 적용하여 그 효과를 추정하였다. 이를 위해 1998년부터 2000년까지 한국전산원에 정보화근로사업 예산지출내역서를 보고한 7개 중앙행정기관(행정자치부. 외교통상부, 건설교통부, 보건복지부. 법제처, 대검찰청, 기상청)을 대상으로 하였으며, 정확한 추정을 위해 한국은행에서 1998년을 기준으로 작성하여 2001년 7월에 발간한 산업연관표(인장표)를 이용하였다. 산업연관분석을 위해 먼저 정보화근로사업의 예산지출내역을 정보화기반조성 예산지출부분과 인건비 지출부분으로 구분한 다음 각 부문별 예산지출내역을 산업연관표의 분류기준에 맞추어 재분류하였다. 또한 산업연관분석에 필요한 산업부문별 생산유발계수와 고용유발계수를 도출하였다. 분석결과, 정보화기반조성 예산지출로 인해 45,999명의 고용유발효과가 있었으며. 인건비 예산지출로 인해 2,020명의 고용유발효과가 있는 것으로 나타났다. 따라서 전체적으로 정보화근로사업으로 1998년부터 2000년까지 약 307억원의 예산지출을 통해 약 48.019명의 고용유발효과가 관련산업에서 발생한 것으로 추정되었다. The purpose of this study is to estimate employment induced effects produced by the IT New Deal by introducing the method of the input-output analysis. The seven central governmental agencies were sampled because they reported the whole budget data related to the IT New Deal from 1998 to 2000. For the elaborate estimate, the 「1998 Input-Output Table: Extended Version」 released by the Bank of Korea on July, 2001 was used. The analysis was conducted according to the following steps. First, the budget outlays of the IT New Deal Program were reconstructed based on the classification system of the input-output table. Second, the coefficients of production and employment induced by the industrial sector were drawn in order to estimate the whole effects resulting from the IT New Deal. The analytic results showed that employment induced effect of 45,999 persons was estimated with the budget expenditure invested in purchasing infrastructure equipments and employment induced effect of 2,020 persons was produced with the budget expenditure used in hiring manpower for the IT New Deal.

Many changing mankind's thought and recognition have affected our history, it is same that dance has become a new concept-dance art under the concept that experiment of a new formality and change are creation. Dancer's feeling is exposed through dance is a phenomenon of carrier which independently embodies self. Dance is a harmony between time and space and a harmony made by rhythmic movement and dance composition. Dance is an art expressing feeling and some situations intentionally dr not by moving its body. The way of communication has been changed since the introduction of the New Dance. In traditional dance, there was no sharply defined boundary to divide spectators and performers, that is, the object and the subject of communication. With the New Dance, there established modern theatres, which separated performers from spectators. With the New Dance, the dance itself became interpretive activity. The New Dance remodelled the traditional dance and introduced some element of ethnic dance from other countries. For example, the costume became so diversified in the New Dance that the range of expression also became expanded greatly.
