본 연구는 신체질량지수에 따라 20대 여성의 신체조성과 유산소, 무산소 체력간의 비교 및 상관관계를 알아보고자 하였다. 신체 질량지수에 따라, 저체중 집단, 정산체중 집단, 과체중 집단 각 50명의 여성을 연구 대상자로 선정하였으며, 신체조성과 운동부하검사를 통해 유산소 체력, Wingate test를 통해 무산소성 체력을 측정하였으며, 다음과 같은 결과를 도출하였다. 신체조성과 유산소, 무산소 체력간의 밀접한 상관관계를 나타내었으며, 집단별 유산소 및 무산소 체력간의 차이에서는 정상체중, 과체중, 저체중 순으로 뛰어난 체력수준을 나타내었다. 결론적으로 현대사회에서의 무분별한 다이어트를 통한 저체중에 비해 정상체중 및 과체중이 체력적인 부분이 뛰어나다는 것은 저체중 집단의 건강상의 문제점이 발생할 수 있다는 가능성을 제시하였다. 추후 연구에서는 다양한 대상에서의 연구를 통해 건강한 체력수준과 신체조성의 기초자료가 제시되어야 할 것이라 생각한다. This study investigated the effect of 12 weeks" aerobic exercise program on obese men"s body composition, blood lipids, C-Reactive Protein(CRP) and Homocysteine by carrying out the program at 60%HRmax five times a week. As research subjects, 14 obese men were selected who were in their late 20s or in their early 30s with over 25% of body fat percentage. This study came to the following conclusion by observing the subjects before the exercise program and 8 weeks and 12 weeks after the exercise program. In the aerobic exercise group, it was found that their weights and body fat percentages significantly decreased after 12 weeks" program (p<.05). Although there were no significant differences in the body fat percentage, TC, TG, HDL-C, LDL-C, CRP and Homocysteine, there was some change found in the values with positive patterns. Consequently, this research is considered to suggest a new possibility of improving the vascular disorder inducing factors of obese men in their middle 20s or early 30s through aerobic exercise. For further studies, it seems necessary to carry out an accurate observation into obese men"s exercise types, various periods of exercise, life styles and patterns and even their eating habits, which is different from the research subjects for this study.

The group was randomly set into a normal humidity group (n=15) and a high humidity group (n=15). The temperature of the training environment was set to 33.0±1.0°C, and the humidity setting was set to 50.0±3.0% for the normal humidity group and 70.0±3.0% for the high humidity group, and training with 60% intensity of V·O₂max was performed 3 times a week for 8 weeks. Measurement variables weer body composition, blood lipids, and lactate. All statistics were analyzed by SPSS ver 24.0, and paired t-tests were used to verify the differences between before and after training. Repeated measure ANOVA was performed to examine the effects between groups and periods. All statistical significance levels were set at p<.05. Results: The results of this study are as follows. 1) There was no significant change in skeletal muscle mass in the body composition variable, but there was a significant decrease in body fat (p<.05). 2) For blood lipids, HDL-C, LDL-C, GLU, and TG excluding TC showed improvement effects, and significant differences between the periods (p<.05, p<.01, p<.001). 3) There were no significant differences in each variable in the case of blood lactate. Conclusion: In conclusion, training according to humidity environment can expect improvement effect on the human body. However, it is thought that clear distinction, control of training environment and living environment are needed because continuous exposure to high humidity can cause various diseases.

젖산염에 의한 대퇴동맥과 흉추대동맥의 혈관 이완 : 사전 연구

김기현(Kim, Kee-Hyun),차광석(Cha, Kwang-Suk),성동준(Sung, Dong-Jun),진승모(Jin, Seung-Mo) 한국웰니스학회 2017 한국웰니스학회지 Vol.12 No.3

젖산염은 혈관이완물질로써 다양한 동맥에서 이완을 조절한다. 국소혈관 이완물질로써의 중요함에도 불궇고 젖산염의 혈관이완기전은 현재까지 명확하지 않다. 따라서 이 연구는 젖산염이 대퇴동맥과 흉추대동맥의 이완기전을 규명하기 위한 사전연구이며, 젖산염의 혈관이완이 조직 특이성을 보일 것이라고 가설하였다. 이 연구에서는 수컷 Sprague Dawley(SD) rat의 대퇴동맥과 흉추대동맥을 사용하였으며, 세로토닌으로 전수축을 유발한 후 다양한 조건에서 젖산염에 의한 혈관이완을 등척성 수축실험을 통해 확인하였다. 대퇴동맥에서 젖산염은 농도의존적으로 이완을 유발했으며, 전압의존성 K+채널 억제제인 4-aminopyridine와 pH보정에 의해 혈관이완이 억제되었다. 또한 젖산염은 흉추대동맥의 혈관내피에 비의존적으로 이완을 유발했으며, 산화질소 억제제인 L-NAME 전처리 조건에서도 유사하였다. 이와 같은 결과는 젖산염에 혈관이완은 동맥조직에 따라 다른 기전을 갖고 있는 것으로 생각되며, pH, 이온채널, 그리고 혈관내피층 등 다양한 기전의 추후 연구가 요구된다. Lactate is a vasodilator that regulates relaxation in various arteries. Despite its importance, lactate-induced local vasodilation is not well understood. Therefore, the aim of this pilot study was to examine the mechanism of lactate-induced vasodilation in the femoral artery and thoracic aorta of Sprague-Dawley rats. We hypothesized that lactate-induced vasodilation was tissue-specific. Lactate-induced vasodilation was measured under 5-hydroxytryptamine preconstriction conditions. In the femoral artery, dose-response vasodilation by lactate was observed, whereas 4-aminopyridine and pH-adjusted conditions prevented lactate-induced vasodilation. In addition, lactate-induced vasodilation independent of the vascular endothelium in the thoracic aorta, and was similar under pretreatment with N omega-nitro-L-arginine methyl ester, a nitric oxide inhibitor. These results suggest that vasorelaxation in lactate may have different mechanisms, depending on the arterial tissue. Further studies on the effect of various factors such as pH, ion channels, and the vascular endothelial layer are required.

Modern high-speed transceiver requires stringent timing margin to guarantee bit-error tolerant data transmission, so we propose a data path’s behavioral (or t iming) model that incorporates lossy channels. Since realistic channel s such a HDMI and DP cables have a frequencydependent loss, both transmit/receive sides (TX and RX) should equip adequate equalization techniques to open an equivalent data eye. On TX side, there is a feedforward equalization (FFE) tries to equalize the number of tab and the gain of each coefficient are determined. On RX side, there are Linear equalizer (LE) and decision-feedback equalizer (DFE). For every configuration, the eye diagram is derived to see how the equalizers (FFE, LE, DFE) boost the closed data eye due to lossy channel.
