The purpose of this study was to the effects of exercise intensities in physical activity of 8 weeks, on fitness, blood lipid for middle school students with intellectual disabilities. Participants of the research were allocated by low-intensity(n=8, 40~54%HRR), middle-intensity(n=8, 55~69%HRR), and high-intensity(n=9, 70~85%HRR) exercise groups wirelessly. For setting and maintenance of individual exercise intensity, wireless heart rate monitor(RS-400, POLAR, Finland) was used. Fitness, BDNF, and blood lipid were measured equally before participating in physical activity and 8 weeks after participation. As a result, fitness and agility of high-intensity exercise group were significantly increased than low-intensity exercise group. BDNF of high-intensity exercise group was also significantly increased than low-intensity exercise group. For blood lipid, only total cholesterol showed differences by exercise intensity group and exercise group more than middle intensity showed significant reduction. In conclusion, when giving same exercise to middle school students with intellectual disabilities, fitness and BDNF were increased the mostly in high-intensity exercise group and total cholesterol was effective from the exercise of more than middle intensity.

The purpose of this study is to investigate the effect of exercise mode and anti-hypertensive drug responding status on the cardiovascular response and perceived exertion in acute coronary syndrome (ACS) patients. Seventy-five patients who participated in six-week exercise rehabilitation therapy performed a treadmill running and a cycle ergometer exercise at intensities of 60%HRR and 85%HRR respectively. Systolic and diastolic blood pressure, mean arterial blood pressure (MAP), rate pressure production (RPP), and ratings of perceived exertion (RPE) were measured. The results of cardiovascular response by the different exercise modes with moderate and intensive intensity of anti-hypertensive drug responder and nonresponder ACS patients were following: First cycle ergometer exercise induced significantly higher SBP, DBP, MAP, RPP and MAP than treadmill running exercise at the intensities of 60%HRR and 85%HRR in both anti-hypertensive responder and nonresponder ACS patients (p<0.05). Secondly anti-hypertensive nonresponder ACS patients had significantly higher DBP and MAP that anti-hypertensive responder ACS patients at all the exercise modes (p<0.05). Finally there was no difference of RPP between anti-hypertensive responder and nomresponder ACS patients, although anti-hypertensive nonresponder ACS patients showed higher blood pressure and RPP than anti-hypertensive responder ACS patients. In conclusion, cycle ergometer induced increased cardiovascular response at same intensities of treadmill running exercise and anti-hypertensive nonresponder ACS patients had even more increased cardiovascular response than anti-hypertensive responder ACS patients with no difference in perceived exertion during exercise. These results suggested that cycle ergometer exercise should be greatly careful with the risk of higher blood pressure, especially for those who are patients with hypertensive blood pressure.

The purpose of this study was to clarify the casual effects among participants'curiosity, the perceived exertion and the exercise emotion on the exercise adherence behavior in marine leisure sports. The subjects for the study was 491 students who registered for the curriculum on marine leisure sports(SCUBA diving, Windsurfing, Yacht). They answered to 4 kinds of questionnaires. The descriptive analysis and the reliability analysis were accomplished through SPSS 18.0. The correlation analysis and the confirmatory factor analysis were conducted for verifying the validity of the research model with AMOS 18.0. The verification for the structure equation modeling was conducted to investigate the casual relationship among factors. The results was as follows. First, there was the causality between the participants'curiosity on the marine leisure sports and the exercise emotion, the emotion and the exercise adherence behavior, the curiosity and the behavior. Also, the exercise emotion was the partial mediating variable of the causality between the curiosity and the exercise adherence behavior. Seconds, when the exercise intensity was heavy, the rate of the positive emotion was low and the opposite was high. When the exercise intensity was heavy, the probability, predisposing and reinforcing were low. A strong will for doing exercise showed in case the exercise emotion was positive with high probability, predisposing and reinforcing. The exercise emotion was the partial mediating variable of the causality between the perceived exertion and the exercise adherence behavior.

일방향 응고법으로 주조된 아공정 회주철의 파단면을 주사전자현미경을 이용하여 분석하였다. 회주철에서는 흑연의 형태변화로 인하여 파단면의 형상에 큰 차이점이 유발되었으며, 이와 같이 다양한 파단면의 특성분석을 위하여는 주사전자현미경의 이차전자(secondary electron)를 이용한 입체사진(stereopair micrograph)을 촬영하여 입체전인 관찰을 수행하는 것이 효과적이었다. 일방향으로 응고된 D형 흑연을 갖는 회주철이 A형 회주철에 비하여 열등한 기계적 성질을 갖는 것은 극히 미세한 망장(網狀)의 혹연조직과 오스테나이트의 이차 수지상 조직(secondary dendrite arms)의 형성에 기인하는 것으로 확인되었다. 이들 조직은 고 강도의 철상을 거치지 않고 주로 흑연상 주위의 취약한 부분을 통하여만 파괴가 전파되도록 유도함으로써 D형 주철의 파괴강도를 저하시킴이 발견되었다. A형 회주철에서는 조직의 조대함으로 인하여 고 강도의 철조직이 파괴에 참여하게 되어 파괴강도를 높여주는 것으로 확인되었다.
