This study is purpose for suggesting correlations an among obesity assessment index(BMI, %BF) and the cardiovascular disease risk factors. The target was 379 male and 377 female in their 20s~60s who lived in Seoul and had taken the regular check up in C health-checkup center in 2018. The both groups by gender showed statistically significant differences in the variables of BMI, WHR, %BF, TG, HDL-C, FPG SBP, DBP(P<.000). The male group’s BMI showed statistically significant, positive correlations in the variables of weight, SBP, DBP, TC, TG, FPG, WHR and BFM, but showed some negative correlations (P<.000) in the HDL-C. The male group’s %BF showed some negative correlation in the HDL-C(P<.000), but showed statistically significant, positive correlations in the other variables(P<.000). The female group’s BMI and %BF showed some negative correlations in the variables of height and HDL-C, and positive correlations in the other variables(P<.000). It was identified that the non-risk factor group’s means in the variables of age, weight, SBP, DBP, TC, TG, LDL-C, FPG, BMI, WHR, %BF and BFM were lower than the risk-factors possessing group’s means, and the former group’s HDL-C means were higher(P<.000). In this study, it was found that the levels of BMI and % BF being suggested as the criteria of obesity got higher, the cardiovascular diseases(CVDs) risk rate became higher.

This study aimed to find out whether any correlation between the cardiovascular risk factors and the obesity would be appeared depending on the ages and the obesity levels. This study was conducted targeting 649 males and 460 females in their ages of 20s-60s who had regular checkups across 2014-2015 year. In order to verify this study’s hypothesis, this study set 4 groups on considering the group composition by age and the BMI, %BF level and assigned the all subjects into the 4 groups. And the all subjects were checked their body propositions, their pressures and blood lipid composition. The all data in this study were statistically analyzed in use of SPSS-PC Version 18.0. This study used the independent t-test, One-Way ANOVA & LSD(Least Difference) method. In the intergroup difference by age, it was found that each group showed statistcially significant difference in the variables of body compositions(BMI, WHR, %BF, and BFM), the blood lipid composition(TC, TG, LDL-C, and FPG) and the blood pressure(SBP, DBP)(p〈.000). In the test results of the groups classified depending o the obesity levels, it was found that the both values of age and %BF were the highest in the Group C, and the values of height, weight, SBP, TG and HDL-C were the highest in the Group B. And the values of TC, LDL-C, FPG, BMI, WHR, and BFM were the highest in the Group D. For the variables of BMI and %BF which are currently most frequently used as the obesity criteria, the relevances between obesity and the risk factors corresponding to BMI and %BF respectively were appeared differently, but it was appeared that if one of both BMI level and %BF level is high, the risk level of cardiovascular diseases will eventually became high.

The purpose of this study lies in figuring out the effect of plantar transformation of 60 male office workers in their 50s on their static balance and physical strength, along with supplementation of the weak points of plantar form. Those subjects ith transformed plantar were divided into normal plantar(15), pes cavus(15), pes planus(15), hallux valgus(15). Entire subjects were measured of their weight, BMI, BF rate with multi-frequency Impedance (X-scan plus Ⅱ), and static balance, pes cavus, pes planus depending on the pressure distribution affecting plantar were analyzed with Gaitview AFA-50(Alps electric Co., Lid, Korea. Hallux angle of the hallux valgus was measured with goniometer, and static balance, cardiorespiratory endurance, lower extremity endurance, flexibility, explosive muscular strength and quickness were measured. One-way ANOVA and Turkey"s post hoc test were conducted to see the difference between the transformed plantar as the data process. Significant level was P<.05 with the results as below. Pressure distribution pre. post static balance by plantar form showed significant difference between the groups, while the pressure distribution of both side showed insignificant difference. Exercise stress test showed considerable difference in exercise duration by plantar form, while there were insignificant difference in maximum oxygen intake, maximum heart rate, titration number of heart beat. Isokinetic test showed significant difference in protractor and flexor of both sidei by plantar form, and insignificant difference in the rate of flexor defect, and significant difference in the defect rate of protractor of both side. No significant difference appeared in the rate of muscular strength of both side. Seeing from synthesized results, there were significant differences in pre, post static balance, exercise duration of cardiorespiratory endurance, lower extremity strength and protractor defect rate of both side and quickness by plantar form. Accordingly, plantar transformation can be considered as greatly influential on static balance, exercise duration, lower extremity strength and quickness.

The purpose of this study is to observe the relationship between indicators of metabolic syndrome, WHR and %Fat by BMI classification in adult men. The subjects of this study were 500 adult men with ages ranging from 40 to 59 years old who had no physical and congenital problems. These adult men were measured their body composition height, body weight, body mass Index, percent body fat, waist to hip ratio, fast blooding sugar, blood pressure and serum lipids total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride. The result of these variables was analyzed and compared using SPSS 12.0 program. The major analysis employed Descriptive detective, Independent samples t-test and Pearson’s Correlation Coefficient. All statistical significance levels were P<.05. The results of this study were as follows. First, in normal weight group, there was the significance positive correlation between BMI, WHR and %Fat in BMI classification of both WHO and KSSO(Korea society for the study of obesity). Generally in overweight and obesity groups, the classification of KSSO’s BMI had more significance than WHO’s. Second, there was the significance positive correlation between systolic blood pressure, diastolic pressure and fasting blood sugar in overweight and obesity groups of KSSO’s BMI classification. But, WHO BMI classification had no significant correlation in metabolic risk factors. Future studies must be performed with more variables region, gender, age, exercise, alcohol, nicotine and percent body fat, waist circumference indicating distribution of body fat to examine the interaction between BMI and metabolic risk factors.

This study analyzed the differences on what kind of effects instant high level caffeine drink intake inflicts to physical capability, anaerobic power, tiredness and autonomic nerve functions of 16 of Korean elite marathon athletes who are in their 20s. This study covered 16 marathon athletes registered to K institute team and the environments that may affect to them were limited and controlled. Physical capability, maximum oxygen intake, lactic acid analysis, abiotic power and autonomic never function were tested as pre-evaluation and post evaluation was done 1 week after pre-evaluation session with intake of a can of high level caffeine drink(250ml, 61.85mg of caffeine) an hour before the tests were applied. For Physical Fitness, Sit and Reach showed p=.0165 which is statistically significantly high, and Sargent jump showed p=.018 and Reaction Time showed p=.013 which were statistically significantly high. For Anaerobic Power, Peak Power showed p=.032 which was statistically significantly increased. In Fatigue: Blood Lactate, it showed no statistically significant differences and in Autonomic Bioelectric response showed Activity p=.048 and Reactivity p=.016 that were statistically significantly decreased. Intake of high level caffeine drink by athletes can be positive help on increasing physical capabilities, improving performance or relieving stresses, but it is expected hardly no significant difference will be acquired during their actual performances for those elite athletes and it is estimated that there are needs on providing precise information on the potential problems can be caused when such substance is overdosed and/or overused.

반도체 제조에 사용하는 특수가스를 공급하는 설비는 인화성·독성·부식성을 지닌 유해·위험물질을 주로 취급하는데, 이러한 공급설비로는 주로 가스캐비닛이 사용되고 있다. 가스캐비닛 내 파열판을 통한 누출, 누출 개구부의 확대가 가능한 누출, 누출 개구부가 확대되지 않는 누출의 케이스별로 공급장치 내부 상태 및 외부로의 확산 영향을 누출 원인별로 분석하였다. 이 경우 누출 단면적에 따라 공급장치 외부로 가스가 누출되는 경우가 발생함을 확인하였다. 외부로 누출되는 가스의 농도에 따라 폭발분위기 형성 등 위험성이 존재하는 요인으로 작용하며, 위험에 따라 공급설비의 안전운전절차 등 제반 조치사항을 다시 검토할 필요가 있음을 확인하였다. Facilities that supply specialty gases used in semiconductor manufacturing mainly handles with hazardous and dangerous substances with flammable, toxic, and corrosive properties, and gas cabinets are mainly used as such supply facilities. The effects of the supply facilities were analyzed for each leak through the rupture disk in the gas cabinet and a leak where the leak hole. In this case, gas leaked to the outside depending on the leak area. It is a factor that creates a risk depending on the concentration of the leaked gas. Depending on the risk of leakage, all measures such as safe operation procedures should be reviewed again.
