무용전공 대학생의 스트레스 요인 분석

한태준,우태화,오상훈 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.1

Stressors which dance specialty university student have been suffered from during activity in dance were analyzed through open-questionnaire, the participants in this survey were 228 dance specialty university student, sort questions according to the affinity and similarity of them in the aspects of conception, questionnaire was summed up in six factors and twenty questions. Arranged twenty questions were determined by the fifth levels of Likert's type scale to be good for responses. As the result of analysis of responded contents, they were sorted as main six factors like that university professor, training, school, finance, individual, rest. As Jim Taylor told, dancers are apt to have disease and injuries when dancers are under the stress, and those who have abnormal increase of decrease in one's own weights can have more stress. The way of conducted a good performance by dance specialty university student is that dancers should have responsibility as worker and have pride as artist, many study and analysis will be necessary if there are any other in actual circumstances or not in actual circumstances.

運動選手의 動機化에 關한 考察

韓泰俊 慶星大學校 1986 부산수산대학 논문집 Vol.7 No.2

Motivation is viewed as necessary, but not sufficient condition for performance. The sources of potential motivation for the athlete are numerous and extremely diverse. The total of motivation of athlete is seen as a combination of factors grouped under the broad categories: dimensions within athlete, performance consequences dimension, athletic competition dimension and task charactristic dimension. Selected factors within each category are need to achievement, aspiration level, personality, goal set, positive vs negative reinforcement, success vs failure, rewards, threat and administration of punishment, ability of competition, competition, social presence, Hawthorne effect and information feedback etc. The factors affecting motivation do not operate independantly but, rather interact to produce a total level of motivation. It is important, therefore, that the teacher or coach have information about each of the classes of factors.

파래의 포자형성률을 이용한 해양생태독성시험 방법에 관한 연구

한태준,한영석,박경수,이승민,Han, Tae-Jun,Han, Young-Seok,Park, Gyung-Soo,Lee, Seung-Min 한국해양학회 2008 바다 Vol.13 No.2

해조류를 이용한 수생태독성시험법으로 대형 녹조 구멍갈파래(Ulva pertusa)의 포자형성률을 endpoint로 사용하는 독성시험법이 개발되었다. 생태독성시험을 위한 최적 조건은 광조사량 $100\;{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, 수소이온농도(pH) $7{\sim}9$, 염분 $25{\sim}35\;psu$ 그리고 수온 $15{\sim}20^{\circ}C$이다. 본 시험법의 민감도는 표준중금속(Cd, Cu, Pb, Zn)을 가지고 확인하였고, 오염 시료에 적용 가능성은 9 지역의 산업폐수 또는 생활하수 오니 용출액(elutriate)을 이용하여 이루어졌다. 네 종의 중금속에 대한 포자형성률 억제 반응의 $EC_{50}$ 값을 산출한 결과, 구리($0.062\;{mg}{\cdot}L^{-1}$) > 카드뮴($0.208\;mg{\cdot}L^{-1}$) >납($0.718\;mg{\cdot}L^{-1}$) > 아연($0.776\;mg{\cdot}L^{-1}$) 순으로 민감하게 나타났는데, 이러한 결과는 US EPA에서 제공하는 ECOTOX DB에 탑재되어 있는 국제적으로 공인된 수생태 독성시험법 결과와 비교해 볼 때, 더 높은 중금속 민감성을 보였다. 현장시료에 대한 포자형성률 억제 반응의 $EC_{50}$ 값을 살펴보면 산업폐수오니($EC_{50}=6.78%$)에서 가장 높고 정수장오니($EC_{50}=15.00%$)에서 가장 낮은 독성 반응을 보이는 것으로 나타났다. 산업폐수 또는 생활하수오니 용출액내에 함유된 독성원 농도와 산출된 $EC_{50}$ 값 사이에 상관성을 밝히기 위해 Spearman rank correlation test를 실시한 결과, 구리, 카드뮴, 납 그리고 아연이 구멍갈파래의 포자형성 저해 반응과 밀접한 상관관계가 있는 것으로 확인되었다. 본 시험법은 독성 민감성이 높고, 사용이 간편하고, 경제적이고, 해석이 용이하며, 대량의 시험재료 확보가 상시 가능하고, 배양이 어렵지 않아 매우 편리한 시스템이라고 할 수 있다. 특히, 파래의 포자형성 과정이 파래 집단의 성쇠와 밀접한 관련이 있으므로 생태적인 의미까지 포함하기에 보다 다양한 독성물질을 대상으로 독성민감성이 확인될 경우, 수서 생태독성을 진단하는데 유용한 프로토콜로 사용될 수 있을 것으로 사료된다. 또한, 파래류는 넓은 지리적 분포와 속 수준에서 포자형성 과정의 유사성 때문에 전 세계적으로 광역적 적용이 가능할 것으로 기대된다. As an aquatic ecotoxicity test method, a bioassay using the inhibition of sporualtion of the green macroalga, Ulva pertusa, has been developed. Optimal test conditions determined for photon irradiance, pH, salinity and temperature were $100\;{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, $7{\sim}9$, $25{\sim}35\;psu$ and $15{\sim}20^{\circ}C$, respectively. The validity of the test endpoint was evaluated by assessing the toxicity of four metals (Cd, Cu, Pb, Zn) and elutriates of sewage or waste sludge collected from 9 different locations. When the metals were assayed, the $EC_{50}$ values indicated the following toxicity rankings: Cu ($0.062\;mg{\cdot}L^{-1}$) > Cd ($0.208\;mg{\cdot}L^{-1}$) > Pb ($0.718\;mg{\cdot}L^{-1}$) > Zn ($0.776\;mg{\cdot}L^{-1}$). When compared with other commonly used bioassays of metal pollution listed on US ECOTOX database, the sporualtion test proved to be the most sensitive. Ulva sporulation was significantly inhibited in all elutriates with the greatest and least effects observed in elutriates of sludge from industrial waste ($EC_{50}=6.78%$) and filtration bed ($EC_{50}=15.0%$), respectively. The results of the Spearman rank correlation analysis for $EC_{50}$ data versus the concentrations of toxicants in the sludge presented a significant correlation between toxicity and four heavy metals(Cd, Cu, Pb, Zn). The method described here is sensitive to toxicants, simple to use, easy to interpret and economical. It is also easy to procure samples and maintain cultures. The present method would therefore probably make a useful assessment of aquatic toxicity of a wide range of toxicants. In addition, the genus Ulva has a wide geographical distribution and species have similar reproductive processes, so the test method would have a potential application worldwide.

중파자외선에 대한 남극산 해조류의 광합성 및 자외선 흡수물질 형성 반응

한태준,박병직,한영석,강성호,이상훈 한국환경생물학회 2002 환경생물 : 환경생물학회지 Vol.20 No.3

남극에 생육하는 5종의 홍조류(Curdiea racovitzae, Gigartina skottsbergii, Mazzaella obovata, Myriogram- me manginii, Palmaria decipiens)를 대상으로 인공 중파 자외선과 태양광선에 대한 종별 생리적 반응을 광합성이라는 파라미터를 사용하여 조사 연구하였다. 실험실 연구 결과,종간에 중파 자외선에 대한 내성 차이가 확인되었으며 이러한 차이는 각 종들이 채집되기 전에 서식하고 있었던 수심과 매우 밀접한 관계가 있어서 20~30m의 수심에서 채집된 M. manginii와 P. decipi-ens의 자외선 내성이 다른 종들에 비하여 작게 나왔다. 본 연구 결과는 서식지 주변의 광환경이 해조류의 자외선 내성을 결정해 주는 한 요인이라는 가설을 입증해주었을 뿐 아니라 형광 변화를 이용한 광합성 측정법은 자외선 내성을 타진하는데 있어서 매우 신속하고 비파괴적인 방법으로 이용될 수 있음을 입증하였다. 두 종의 홍조류(M. manginii, P. decipiens)를 대상으로 태양광선 하에서의 광합성 효율을 관찰한 결과, 정오 에 최저 광합성을 보인 반면 저녁에는 광합성 능력이 회복되는 현상을 나타내었다. 이같은 동적인 광저해 현 상(dynamic photoinhibition)은 일종의 광적응 능력으로서 식물이 비교적 강한 태양광선에 노출된 지역에 성공적으로 서식하는데 크게 기여하는 것으로 사료된다. 본 연구에서는 또한 태양광선내 중파자외선 포함 유무에 따라 광합성 회복 속도에 차이가 나는 것을 볼 수 있었는데 중파자외선이 포함된 태양 광선 하에서는 광합성의 회복이 느린 반면,중파 자외선이 제거된 조건에서는 광합성이 비교적 빨리 회복되는 것을 관찰할 수 있었고 이는 중파 자외선이 광합성 회복 기작을 지연시키는 작용을 한 것으로 해석될 수 있다. 야외에서 자외선 민감성을 비교한 결과, P decipiens가 M. manginii에 비하여 자외선 내성이 큰 것으로 나타났는데,두 종 공히 조간대로부터 조하매 상부까지 서식하는 종임에도 불구하고 이러한 내성차이를 보인 이유는 자외선 흡수물질의 정량적인 차이에 기인한다고 할 수 있다. M. manginii와 P. decipiens에서 발견된 자외선 흡수물질의 양은 약 1.2 정도의 비율을 보였는데 이러한 정량적 차이가 자외선 민감성에 기여한 것으로 사료된다. 본 연구에서는 또한 계절별 그리고 채집 수심별로 자외선 흡수물질의 정량적 차이를 발견할 수 있었는데 태양광선이 풍부한 여름철에 그리고 고광량이 도달되는 수심 얕은 곳에 서식하는 개체가 더욱 많은 양의 자외선 흡수물질을 함유한 것으로 나타났다. Effects of artificial and solar UV-B radiation on five rhodophytes (Curdiea racovitzae, Gigartina skottsbergii, Mazzaella obovata, Myriogramme manginii, Palmaria decipiens) from Antarctica have been investigated using PAM fluorescence in laboratory and in the field. Laboratory studies showed that there were significant differences in the UV sensitivity between different species, and that the differences appeared to be correlated with the depth of collection of the specimens. It was apparent from the observations that the samples such as M. manginii and P. decipiens collected from 20∼30 m depths were more sensitive to UV-B radiation compared with those collected from shallower depths. The present study confirmed that an acclimation to the surrounding light regime could be an important factor to determine the UV-sensitivity of a species or individuals and that PAM measurements are rapid and non-destructive methods to evaluate UV influences. From field studies on M. manginii and P. decipiens it was observed that both plants exhibited changes in the effective quantum yield, with the minimum values at noon followed by a recovery in the evening. Photoinhibition occurred in these species could therefore be accounted for by so-called dynamic photoinhibition. It seems likely that this protective mechanism may contribute to survival of the species in shallow water where they may encounter intense solar radiation. The presence or absence of the UV-B component under solar radiation differently affected the photosynthetic recovery process, and the rate of recovery was much slower in UV-present than in UV-absent conditions. Functional role of UV-B appears to delay the recovery of photosynthesis in the studied macroalgae. Differential sensitivity to UV-B recognised between M. manginii and P. decipiens seemed to correspond well with the amount of UV-absorbing substances(UVAS) contained in the respective species. Higher tolerance to solar radiation by the latter species may be due to the higher amount of UVAS. There were variations of UVAS concentrations in algal thalli depending on the season and depth of collection.
