유승희,전종목 경희대학교 체육과학연구소 2000 體育學論文集 Vol.28 No.-
From March-25, 2000 to April-2, 2000, we investigated anthropometry, body composition, and general lifestyle of 157 collegiate students in Kyung-Gi province and 106 soldiers of the Korean Army Soldiers in Kang-Won province. The results were as follows : 1.There was no significant difference of the height between the students and the soldiers. The Weight of the students was 64.9±7.8kg compared to 69.3±7.1kg of the weight of the Army soldiers. The percent body fat was 17.0±4.1% and 14.8±3.2% for the students and the sold-iers, respectively. 2.The trend of height is that the most highest population is the under fat groups, with the students 173.8±5.9cm and the soldiers 173.6±6.0cm. The population with obese groups had the lowest height. 3.TBW of the soldiers was 40.9±4.2ℓ, which is about 3.7 ℓ more than TBW of the students. And the soldiers had more protein and mineral of body, about 1.4kg and 0.14kg. respectively. 4.In students, the obese group had the most TBW, 38.0±2.8ℓ. In sold-iers, the under fat soldiers, however, had the most TBW, 41.2±4.2ℓ. 5.The percents of people with the iregular lifestyle were 79% and 17%, the students and soldiers, respectively, and the percent of people drinking three times per week were 29% and 3%, the students and soldiers, respectively. 6.51% in the students and 75% in the soldiers were smokers, and 64% in the students and 85% in the soldiers considered them healthy. 7.65% in the students and 7% in the soldiers have taken an irregular meal and 50% and 15% often had instant food. 8.25% in the students and 100% in the soldiers take an regular exercise, and frequency is 3 times per week and 5 times per week, students and soldiers respectively. 9.In collegiate students, Pearson coefficient correlation between height and weight was proportional with r=0.320, between height and LBM with r=0.565, and also weight and WHR with r=0.490, weight and LBM with r=0.900, weight and percent body fat with r=0.559, WHR and LBM with r=0.311, percent body fat and WHR with r=0.515, smoking amount and lifestyle with r=0.277, smoking amount and frequency of drinking with r=0.370, but height and percent body fat had inverse proportion with r=-0.342. 10.In Amy soldiers, Pearson coefficient correlation between height and weight was proportional with r=0.675, and also between height and LBM with r=0.744, weight and WHR with r=0.298, weight and LBM with r= 0.932, percent body fat and WHR with r=0.284. But Pearson coefficient correlation between percent body fat and smoking amount had inverse proportion with r=-0.240.

The purpose of this study was to evaluate the results of analysis of covariance (ANCOVA) with ages that can be controlled through this study, taking into account the fact that adult males can bring a direct impact on the body mass index (BMI) level and blood pressure, and physical fitness. The subjects of this study was 243 adult males, who has no case past history, and BMI groups were divided in three groups (normal, 18.5~22.9 kg/㎡; over weight, 23~24.9 kg/㎡; and obesity, over 25 kg /㎡). The results were analyzed statistically using ANCOVA, and Bonferroni test was used in the event of a significant F-ratio (p<.05). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the obesity group was significantly higher than the normal group, respectively (p<.05).VO₂max in the obesity group was significantly lower than the normal and overweight groups, respectively (p<.05). Isokinetic thigh muscle strength in the normal group was significantly higher than obesity group at three variables (knee flexion left, KFL; knee extension right, KER; knee extension left KEL), respectively (all, p<.05). The results of the push-ups, in the obesity group was significantly lower than the normal group (p<.05). Ages that can be controlled through the analysis of covariance, taking into account the results of this study in accordance with the increase of age, the BMI affects respectively.

The purpose of this study to explore and conclude relationships between body mass index (MBI) level and blood pressure, VO₂max and isokinetic strength. The subjects chosen for the study were sample size of 211 middle-aged women divided into three groups(normal, 18.5~22.9 ㎏/㎡; overweight, 23~24.9㎏/㎡; obese, over 25㎏/㎡) according to their BMI level. The data was analyzed by analysis of covariance(ANCOVA) with age as the covariate via SPSS 18.0 soft program. One-way ANOVA was used because the relationship between age and BMI cannot be established. Bonferroni test was performed as post-hoc analysis to obtain the results hereafter with significance level set at α=.05. First, the obese group showed higher systolic blood pressure(SBP) and diastolic blood pressure(DBP) than that of the normal group, with significance(both p<.05). Also SBP was significantly higher in the overweight group than the normal group(p<.05). Second, the obese group’s VO₂max was lower than those of the overweight and normal group, with significance(both p<.05). Lastly, isokinetic strength in the normal group was significantly higher than the obese group in four variables(Knee flexion right, KFR; knee flexion left, KFL; knee extension right, KER; knee extension left, KEL) (in which of all p<.05) while KER and KEL was significantly higher in overweight group than in the obese group(both p<.05). Therefore it can be concluded that BMI level has influence on blood pressure, VO₂max, and isokinetic strength, calling for more awareness on the importance of middle-aged women’s weight control. Also the results can possibly serve for studying and developing activities that consider middle-aged women’s shape and physical.

Obesity is being regarded as a disease which causes the most serious public health problem in single disease. It also has a big impact on mortality directly and indirectly. The purpose of this study was to investigate the effects of low intensity walking for 12 weeks on body composition, physical strength, blood content and nutrition uptakes in obese women. The subjects of this study were 17 women in middle ages, who has no case past history, and their percent body fat was over 35%. For data analysis, mean and standard deviation scores were indicated, and paired t-test was used at p<0.05. After aerobic exercise for 12 weeks, body composition, physical strength and blood contents showed significant differences compared with pre and post respectively. This data suggest that low intensity walking exercise for 12 weeks have any beneficial effects in a major mechanism of physiological variation and obese reduction.

본 실험실에서는 회양목(Buxus microphylla var. koreana Nakai)으로 부터 steroid성 alkaloid인 cyclobuxine D를 분리하였고, 그의 여러 약리작용을 검색하고 있다. 본 연구에서는 cyclobuxine D의 guinea pig lung homogenate에서 prostaglandins의 합성에 미치는 영향과 carrageenin으로 유도한 염증에서 prostaglandin의 합성과 백혈구 유주에 대한 영향을 관찰하였다. Cyclobuxine D (up to 100ug/ml)는 guinea pig lung homogenate에 의한 prostaglandins 합성에 대해서는 현저한 영향이 없었으나, 20mg/kg에서 carrageenin으로 유도된 염증에서 prostaglandin의 합성과 백혈구 유주에 대해 현저한 억제작용을 나타낸다. Aspirin은 vivo와 vitro에서 prostaglandin의 합성을 억제하나, 염증 삼출물에서 백혈구 유주에 대해서는 영향이 거의 없다. Dexamethasone은 vitro에서 외인성 arachidcnic acid를 기질로 가했을때는 prostaglandin 합성에 대해 영향이 없었고 carrageenin으로 유도된 염증에서 prostaglandin의 합성과 백혈구 유주를 억제하였다. 이상의 결과로 cyclobuxine D의 항염증작용은 phospholipase A<sub>2</sub> activity를 저해하여 항염증 작용을 나타내는 것으로 사료되는 corticosteroid와 유사한 것으로 추정된다. Cyclobuxine D was extracted from Buxus microphylla var. koreana Nakai. The effects of cyclobuxine D on the biosynthesis of prostaglandins from arachidonic acid in guinea pig lung, prostaglandin production and leukocyte migration in carrageenin-induced inflammation was investigated. These effects of cyclobuxine D were compared with those of aspirin and dexamethasone. Cyclobuxine D does not inhibit significantly cyclooxygenase in guinea pig lung but reduces prostaglandin concentration and leukocyte migration in inflammatory exudates. These effects of cyclobuxine D differ from that of aspirin which inhibits biosynthesis of prostaglandin in vitro and has a relative small effect on leukocyte migration. Dexamethasone, which does not inhibit cyclooxygenase in vitro, has an effect similar to that of cyclobuxine D on leukocyte migration and prostaglandin production in inflammatory exudates.

We developed the tension mask of which thickness increased from 25 urn to 50 urn to reduce the mask cost and improve the vibration property. First of all, the limitation by which rail structure can support is calculated and the optimal thickness of mask is determined. To prevent the reduction of brightness and brightness uniformity, the dimensions of mask was reassigned. As a result, the increase of mask thickness brought about a reduction in cost and improvement of howling property which had been a weak point of flat CRTs.
Mud handling system 내 cyclone separator의 집진효율 추정을 위한 공기-분체의 CFD 시뮬레이션
전규목(Gyu-Mok Jeon),박종천(Jong-Chun Park) 한국해양공학회 2019 韓國海洋工學會誌 Vol.33 No.1
Drilling mud was used once in the step of separating the gas and powder they were transported to a surge tank. At that time, the fine powder, such as dust that is not separated from the gas, is included in the gas that was separated from the mud. The fine particles of the powder are collected to increase the density of the powder and prevent air pollution. To remove particles from air or another gas, a cyclone-type separator generally can be used with the principles of vortex separation without using a filter system. In this study, we conducted numerical simulations of air-particle flow consisting of two components in a cyclone separator in a mud handling system to investigate the characteristics of turbulent vortical flow and to evaluate the collection efficiency using the commercial software, STAR-CCM+. First, the single-phase air flow was simulated and validated through the comparison with experiments (Boysan et al., 1983) and other CFD simulation results (Slack et al., 2000). Then, based on one-way coupling simulation for air and powder particles, the multi-phase flow was simulated, and the collection efficiency for various sizes of particles was compared with the experimental and theoretical results.
