PURPOSE: This study was designed to create a job description for performance frequency, importance, and difficulty of task elements. And to create an effective curriculum for Korea athletic trainers. METHOD: DACUM workshop involves a trained DACUM facilitator, a coordinator, 2 observers, 2 recorders and a committee of 8 expert workers from field of athletic training. 34 subjects which are necessary in the field of athletic training have been selected by the DACUM analysis. The sample consisted of 34 athletic trainers who performed duties related to athletic training. A survey method was used, and the questionnaire included frequency, importance, and difficulty of task elements in job descriptions using the DACUM method. Using SPSS WIN 12.0, descriptive statistics such as frequency distribution, means, and standard deviation were conducted to examine the subject`s general characteristics, frequency, importance, and difficulties of task performance. RESULT: The job description of athletic trainers revealed 10 duties, 9 tasks, and 61 task elements. On all ten duties, the average performance importance, and difficulty was 3.91, and 2.95 respectively. CONCLUSION: The job description of athletic trainers includes duty, task, and task elements and the definition of a completed job. Thus we recommend a data based trial to confirm and validate the information gathered. The competition of department can be improved, if the result of this research is adapted to the department curriculum related to field of athletic training.

박정규,정흥배,문성환,류태권,류제영,황인영 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.4

1. 금호강물에 대한 상대독성과 수온, 전기전도도의 경우 달서천 내부, 금호강과 달서천의 합류점 하부, 합류점 상부 순으로 값의 크기를 보였고 pH의 경우 역순을 보이므로 달서천이 금호강과 달서천 합류점 하부에 영향을 주는 것으로 사료된다. 2. 금호강 하천수에 대한 Microtox 독성값과 온도, pH, 전기전도도의 상관성은 없었으므로 기존의 일반적인 몇 가지 수질 인자로는 독성변화 및 수준을 판단할 수 없다고 사료된다. 3. 36시간 연속 모니터링을 통해 짧은 시간에도 독성값이 달라지는 것으로 보아 수질의 독성 수준이나 오염 수준을 판단하기 위해서는 연속적인 독성 조사 및 분석이 필요하다고 사료된다. 4. 하천수에 대한 연속 모니터링만으로는 하천 생태 위해도를 평가하기는 어렵다. 따라서, 하천 퇴적물에 대한 특성을 병행하여 조사 분석하는 것이 유해화학물질에 의한 하천 오염을 평가하는 방법이 된다고 사료된다. The main point source of pollution of the Keumho river in Taegu, Korea, stems from waste from the areas of industrial complexes. Although it is widely accepted that pollutants in waste water negatively effects general water quality, it is difficult to evaluate the effluent effect because of varying conditions in ambient water and inconclusive knowledge of causative pollutants. To analyze the water in relation to the industrial effluent in the area, pH, temperature, conductivity, and Microtox toxicity of various river samples were measured. Water samples were collected every 2 hours for 36 hours from Keumho river and Dalseo stream. Data from continuous monitoring for 36 hours showed that effluent in Keumho river originated from Dalseo stream, which is near adjacent to industrial complexes. Change in toxicity and other factors tested during the 36 hours indicated that continuous monitoring was necessary for a satisfactory effluent toxicity test. Furthermore, in addition to water quality monitoring, it was concluded that sediment toxicity also needed to evaluate effluent effects.

A new passive sampler was developed, improving SPMD (Semipermeable Membrane Devices) that contained triolein in nonporous, low-density polyethylene layflat tubing. Experiments to measure PAHs concentration were carried out at four sites (Dukpo, Sochi, Sohwonggando, Yeonmok) on the southern coast of Korea that were contaminated by oil spills. Passive samplers were deployed at 4 and 8 week intervals at each site. Results showed that bioconcentration levels of PAHs were increased in proportion to exposure duration from all sample sites and accumulation in the passive sampler was much higher than in biota at the Dukpo site. Results of these tests suggest that new passive sampler is a useful tool for measuring bioconcentration organic compounds in aquatic environments.

국내 하천 퇴적물 건강성평가를 위한 Microtox 독성시험 조건확립 연구

정홍배,박정규,문성환,류태권,김소정,배철한,황인영 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.4

1. 하천 퇴적물 공극수, 증류수 추출용액 및 유기용매 추출액을 pH6.0~6.5 범위로 조절한 후 Microtox 독성을 측정하는 것이 퇴적물내의 암모니아 독성이 배제된, 유해화학물질 오염에 의한 퇴적물 독성을 평가하는 방안임을 확인하였다. 2. 퇴적물에 대해 공극수, 증류수 추출물, 유기용매 추출물 구분하여 Microtox 독성을 구하는 것이 퇴적물 내 유해화학물질의 독성발현 특성을 예측할 수 있는 기법이라고 사료된다. 3. 조사정점 내 시료 채취 지점간 독성에 편차로 인하여, 동일 정점의 반경 50~100m 내에서 최소 4지점 이상의 퇴적물을 확보하는 것이 해당 정점의 독성 대표값을 산출할 수 있는 방안이 된다고 판단된다. 4. 한강수계인 남한강 지천인 복하천과 양화천, 금강수계인 청주 미호천, 대전 갑천, 낙동강수계인 대구 금호강, 영산강수계인 황룡강 그리고 익산 만경강을 대상으로 한 예비 조사한 결과, 집중연구대상 하천으로의 조건은 금호강이 가장 우수하였다. 5. 하천 퇴적물의 증류수 추출액과 유기용매 추출액의 Microtox 독성값 간의 상호 상관성이 높았다. 그러나, 농축 과정이 용이하므로 정점간 비교를 위한 독성 측정시 유기용매 추출액을 사용하는 것이 바람직하다고 사료되었다. Six rivers were selected as preliminary screening sites to determine the test conditions of Microtox in assessing the toxicity of the sediment. In addition, a pH range of 6.0--6.5 was established in testing pore water, aqueous extracts and organic extracts. Each extractable fraction of sediment showed different toxicities. Therefore, in order to properly examine the toxicity in the sediment, all extractable fractions of sediment samples needed to be tested with Microtox. Thus, sediment samples were additionally collected from at least 4 secondary sites within 50~100 m area of the primary sampling site to reduce any variation or deviation in toxicity assessment. From all sediment toxicity data that was collected from this study, it was concluded that the Keumho river was the most polluted with the highest sediment toxicity of all the rivers analyzed and needed further detailed research on its pollution problem.

대구지역 금호강 및 주요 지천 퇴적물의 시·공간적 독성변화

정홍배,문성환,정진애,김재현,박정규,배철한,황인영 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.4

1. 사전에 선정된 공통 조사 정점들 가운데 KㆍH4(금호대교)이후의 퇴적물 독성이 상부의 것보다 크게 나타났다. 즉, 정점 KH3과 KH4, 그리고 KH4와 KH5 사이에 독성물질 유입원이 있는 것으로 판단되었다. 2. 하천 퇴적물의 독성 수준에 영향을 주고 있는 물질의 종류와 배출원 파악이 필요하였다. 이러한 내용을 향후 계속적 연구 및 조사를 통하여 수행되어야 하는 과제라 사료된다. 3. 퇴적물 시료의 채취 시점에 따라서 동일 정점의 독성 변화가 심하였다. 유해화학물질에 의한 오염 수준과 하천 생태계의 영향을 예측하기 위해서는 하천 퇴적물을 대상으로 경시적으로 독성의 변화를 계속 관측하는 것이 필요하다고 판단되었다. In aqueous ecosystems, the level of toxicity is highly responsive dependant to multiple variables, including rainfall, sunlight, pH, adhesion, etc. Because Korea has particularly distinct wet and dry seasons, the toxicity of pollutants in rivers or streams is dependant on the sampling season and time. In order to examine the effects of rainfall on toxicity, sediment samples were collected from five sites along the Keumho river. It was found that Microlox toxicity levels were generally higher during the dry season than the wet season. It indicated that river pollutants are carried off more quickly by the water during the wet season. As a result, it was recommended that the point sources of pollutants of the Keumho river would be placed between KH3 (Paldalgyo) and KH4 (Keumhogyo), KH4 (Keumhogyo) and KH5 (Dasa).

Marine organisms such as fish (Sebastes schlegeli) and mussels were cultured in sea water tanks placed at Dukpo area which was contaminated by the two oil spill accidents. Results showed that PAHs concentrations in fish tissue were higher than in fish liver. This was explained by the cytochrome P450 IA induction in fish liver after PAHs exposure. Other studies showed that higher PAHs levels were detected in mussels cultures in oil contaminated area than in control site. From these results, we concluded that Dukpo area is still polluted by oil including PAHs and it takes a long time to recover of oil contamination after the oil spill accidents.
