Purpose: This study aims to examine perceived safety management in teachers working for young children with disabilities, to grasp the state and problems of safety management and first-aid education at daycare center for young children with disabilities, and to provide basic materials to develop programs for safety management and first-aid education. Results: 1. For the perception items of accident possibility in daycare centers, career with more than 10 years had higher response in 'very high' and 'moderately high' than 'moderately or very low' and statistically significant difference was found(p < .05). 2. For the perception items of accident prevention in daycare centers, no teaches with at least college education thought that 'it was not possible to prevent' and most of them thought that 'it was totally possible to prevent' and statistically significant difference was found(p < .05). 3. For the performance level of safety management and first-aid items, forty and over(4.73) showed higher than age of 20-29(4.32) and 30-39 of age(4.26) and statistically significant difference was found(p < .05). 4. For the knowledge level of safety management and first aid items, the highest religion was found as Christian(16.96), followed by Catholic(15.33), Buddhism(14.91), and no religion(15.81) and statistically significant difference was found(p < .05). 5. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed safety management and first-aid education( 4,48) had higher performance score than those who did not (4.17) and statistically significant difference was found(p < .05). 6. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed first-aid education(2.77) had higher confidence than those who did not(2.35) and statistically significant difference was found(p < .05). Conclusion: The results suggest that safety management and first-aid education in teachers working for daycare center for young children with disabilities was closely correlated with knowledge and performance levels. Thus, it is necessary to provide continuous safety management and first-aid education for teachers working for day care center for young children with disabilities through regular in-service training. Also further research should be conducted with all subjects and various regions who contact with young children with disabilities.

본 연구는 남자 고등학교 엘리트 그레코로만형과 자유형 레슬링 선수들의 무산소성 운동능력과 요추부 및 슬관절 등속성 근력의 차이를 비교 분석하는데 목적이 있다. 연구 대상자는 고등학교 엘리트 레슬링 선수 16명(그레코로만형 집단 9명, 자유형 집단 7명)이 본 연구에 참여하였다. 선수들의 무산소성 운동능력 측정은 전자기식 에르고미터를 이용하 였고 등속성 근력은 Cybex 770을 사용하여 측정하였다. 연구결과 고등학교 엘리트 레슬링 선수들의 무산소성 파워는 집단 간에 유의한 차이가 나타나지 않았다. 슬관절 등속성 근력은 그레코로만형 집단이 자유형 집단에 비하여 우굴근의 상대근력과 절대근력(p<.05, p<.01)이 유의하게 높았으며, 좌굴근의 상대근력(p<.05)과 좌신근의 절대근력(p<.05)이 유의하게 높은 것으로 나타났다. 요추부 등속성 근력은 그레코만형 집단이 자유형 집단에 비하여 요추부 신근의 절대근력 과 상대근력(p<.05, p<.05) 이 유의하게 높았다. 결론적으로 남자 고등학교 엘리트 레슬링 선수들의 종목별 무산소성 운동능력과 등속성 근력의 차이를 확인할 수 있었으며 종목별 특성과 성장기 선수들의 운동능력을 고려한 과학적이고 체계적인 훈련 프로그램이 계획 및 적용되어야 할 것으로 판단된다. The purpose of this study is to compare and analyze differences between male high school greco-roman and free style wrestler's anaerobic exercise ability and isokinetic muscular strength. The subjects were sixteen high school wrestlers (greco-roman group; n=9, free style group; n=7). Anaerobic exercise ability was measured by computeraided electrically braked cycle ergometer and isokinetic muscular strength was measured by Cybex 770. As results, anaerobic exercise ability was not significantly different between the greco-roman and free style group. The isokinetic muscular strength of knee joint, right flexor was observed a significantly high in the greco-roman group than free style group(relative strength p<.05, absolute strength p<.01) and also, left flexor and left extensor were significantly high in the greco-roman group(per p<.05, p<.05). The isokinetic muscular strength of lumbar, lumbar extensor was observed a significantly high in the greco-roman group than free style group(relative strength p<.05, absolute strength p<.05). In conclusion, we were able to identify the differences between male high school wresters' anaerobic exercise ability and isokinetic muscular strength, and systematic training program considering the characteristics of each sport and the athletic ability of the athletes during their growth period should be planned and applied.
12주간의 트레드밀 운동이 노화 흰쥐 대동맥의 내?중막 두께와 전염증성 사이토카인 및 NGF, VEGF 발현에 미치는 영향

The purpose of this study was to investigate the effects of 12weeks treadmill exercise on aortic intima-media thickness and pro-inflammatory cytokine, and NGF, VEGF expression in aged rats. Sprague- Dawley (SD) rats were used and divided into three groups; Young Control Group (YCG; 3months aged, n=5); Old Control Group; (OCG; 24months aged, n=5); Old Exercise Group (OEG; 24months aged, n=5). Treadmill exercise was performed five days a week for 12 weeks, during the period which time the speed of the treadmill was gradually increased. The results revealed that aortic intima-media thickness was increased in old group compared to the young group, increased in the OEG compared to OCG (p<05). NF-κB protein level was significantly increased in OCG compared to the OEG (p<001). IL-1β level was significantly decreased in OEG compared to the OCG (p<001), and similarly YCG. NGF and VEGF protein levels were highest in the YCG, increased in the OEG compared to OCG (p<.001, p<.01). These result show that regular exercise not only increased vascular function, but also improved pro-inflammatory cytokine level in the aorta, and Regular exercise prevent the hypertrophy of the aorta in the aging. 본 연구는 12주간의 트레드밀 운동이 노화 흰쥐 대동맥의 내・중막 두께와 전염증성 사이토카인 및 NGF, VEGF 발현에 미치는 영향에 대하여 알아보았다. 본 연구를 위하여 Sprague-Dawley(SD) 흰쥐를 젊은 집단(Young Control Group; YCG; 3months aged; n=10), 노화 집단(Old Control Group; OCG; 24months aged; n=10), 노화 운동집단(Old Exercise Group; OEG; 24months aged; n=10)으로 구분하였다. 트레드밀 운동은 시간과 강도를 점진적으로 증가시켜 주 5회, 12주간 실시하였다. 실험결과 젊은 집단에 비하여 노화 집단의 대동맥 내・중막 두께가 증가하는 것으로 나타났으며 노화 운동집단은 노화 집단에 비하여 감소한 것으로 나타났다(p<.05). NF-κB 단백질 수준은 노화 운동집단에 비해 노화 집단에서 증가하는 것으로 나타났으며(p<.001), IL-1β 수준은 노화 집단에 비해 노화 운동집단에서 감소하였으며 그 수준은 젊은 집단과 유사한 것으로 나타났다(p<.001). NGF와 VEGF 발현은 젊은 집단에서 가장 높았으며 노화 집단에 비해 노화 운동집단에서 증가하였다(p<.001, p<.01). 이상의 실험결과 규칙적인 운동은 노화 대동맥의 혈관 기능을 향상시킬 뿐만 아니라 전염증성 사이토카인 수준을 개선시키고 대동맥 내・중막의 비후를 예방하는 것으로 판단된다.
