These days, serious concerns of reinforced concrete have been raised recently over steel-bar corrosion, cracking, the deterioration of durability and structural stress resistance and so on, all due to the effects of exterior factors. Such being the case, in domestic, various repair materials and method systems to keep up with these reinforced concrete deteriorated due to salt damage, carbonation, chemical decay et. developed and applied. However, on-site quality control of various repair materials and method systems isn't achieved desirably because it is depend completely on a men of experience' opinions above all else regardless of various on - site environments. In this background, mock up test with due regard to real on-site environments was performed to secure fundamental data for establishment of desirable on-site quality control. Mock up test using repair mortar analyzed from angles of construction methods, mechanical spraying pressures, W 1M. Construction methods were designed manpower method and spraying method, spraying pressures were designed 32, 42, 52 psi, W/M were designed 14.4, 15.4, 16.4 %. And compressive strength, Chloride ion diffusion coefficient, bond strength, SEM of mock up test specimens were evaluated. In conclusion, we confirmed excellency of mechanical spraying pressures, fined extremely excellency of condition of spraying pressure 42 ps, W/M 14.4% within this study. therefore the results of this study will be useful to provide fundamental data for establishment of desirable on-site quality control.

김용운,정철수,은선덕,이영석 한국운동역학회 2000 한국운동역학회지 Vol.10 No.1

본 연구는 단거리 달리기(200 m)의 곡선 구간과 직선 구간의 동작을 비교 · 분석하여, 운동학적 변인의 차이를 규명하고, 곡선 구간의 동작 메카니즘에 대한 기초적인 정보를 제공하기 위해, 서울체육고등학교의 100 m 및 200 m 달리기 선수 5명을 대상으로 하여, 3차원 영상 분석법을 통하여 동작을 분석하였다. 본 연구에서 도출된 결론은 다음과 같다. 1. 신체중심의 높이는 직선 구간이 곡선 구간보다 높았으며, 신체중심 변위의 변화는 곡선 구간에서 더 컸다. 2. 신체중심의 수평속도는 곡선 구간이 직선 구간보다 컸으며, 곡선 구간에서 내측 스트라이드 국면이 외측 스트라이드 국면보다 컸다. 3. 신체중심의 수평 측면속도는 평균값에서 곡선 구간과 직선 구간이 차이가 없었으나, 속도의 절대값에서는 곡선 구간이 직선 구간보다 컸다. 4. 곡선 구간 내, 외측 스트라이드 국면의 이지, 착지시 접선속도는 차이가 없었다. 5. 스트라이드 길이는 곡선 구간의 외측 스트라이드가 가장 길었으며, 직선 구간, 곡선 구간의 내측 스트라이드 순서로 길었다. 6. 스트라이드 빈도는 곡선 구간과 직선 구간에서 차이가 없었다. 7. 상체 전경각의 평균값은 곡선 구간과 직선 구간에서 차이가 없었으나, 범위는 곡선 구간이 직선 구간보다 컸다. 8. 상체 측경각은 평균값에서 곡선 구간이 직선 구간보다 컸으나, 범위는 차이가 없었다. 9. 상완의 운동범위는 곡선 구간과 직선 구간에서 차이가 없었다. 10. 무릎거양각은 곡선 구간이 직선 구간보다 운동범위가 컸다. 이상의 결과, 단거리 달리기의 곡선 구간에서 직선 구간과는 차별화된 수행 형태를 보였으며, 내, 외측 스트라이드 간에도 상이한 수행 형태를 보였다. This study was conducted to make a comparative analysis of running motion and to examine the differences of kinematice in curved and straight track portion during the 200m sprinting. In this study, five skilled male sprinters of high school served as subjects. The running motions were analyzed using the method of three-dimensional cinematography The conclusions of this study were as follows. 1. Height of the center of gravity in straight portion was higher than that in curved portion, but displacement of the center of gravity in curved portion was higher than that in straight portion. 2. Horizontal velocity of the center of gravity in curved portion was faster than that in straight portion, and in curved portion that of left stride phase was faster than that in fight stride phase. 3. There was no difference in mean value of lateral component of horizontal velocity between both portions, but absolute value of that in curved portion was faster than that in straight portion. 4. There was no difference in tangential velocity at the instant of touchdown and takeoff of both strides on curved portion. 5. Stride length in right stride of curved portion was the longest, and next to that, that of straight portion was, and left stride of curved portion was the shortest. 6. There was no difference in stride frequence between curved and straight portion. 7. There was no difference in mean value of forward lean angle between both portions, but active range of that in curved portion was larger than that in straight portion. 8. Mean value of inward lean angle in curved portion was larger than that in straight portion, but no difference in active range of that between both portions. As the conclusion of this study, it was clear that there were significantly different running patterns between curved and straight portion, and between left and right stride of curved portion.

Obesity which is defined as accumulation of excess body fat, is central factor of insulin resistance syndrome. Recently, it is revealed tat adipose tissue is not simply an energy storage organ but it also secretes a variety of molecules which affect the metabolism of the whole body, those are leptin and plasminogen activator inhibitor-1(PAI-1). Therefore, leptin and PAI-1 are increased in the obese state. Leptin regulates energy homeostasis and satiety and PAI-1 regulates fibrinolytic system. For these reasons, elevated levels of leptin and PAI-1 are considered as link factors between obesity and insulin resistance syndrome. However, the exact regulating mechanism for serum levels of leptin and PAI-1 is not fully understood yet. In this study, to evaluate the regulating mechanisms of serum levels of leptin and PAI-1 according to the weight changes, we measured leptin, PAI-1, physical, metabolic, and endocrine parameters during 10 days of weight reduction and 10 days of regain period in 7 young athletes. The mean body weight change was -4.7 kg(5.0%) in the weight reduction period and -2.4 kg(2.5%) in the weight regain period compared to baseline value. Baseline level of leptin in athletes was 1.7±0.66 ng/ml, which was significantly correlated with body weight, BMI, percent body fat, body fat mass, triglyceride, insulin, and PAI-1. Baseline level of PAI-1 in athletes was 16.6±5.26 ng/ml, which was significantly correlated with body weight, BMI, triglyceride, insulin, and leptin. Leptin was decreased to 0.7±0.39(44% of the basaline value) in the weight reduction period, and increased to 1.9±0.64(119% of the baseline value) in the regain period. PAI-1 was decreased to 7.4±2.72(44% of the basaline value) in the weight reduction period, and increased to 22.8±7.33(138% of the baseline value) in the regain period. The changes of leptin during weight reduction period were significantly correlated with the changes of insulin(r=0.890, P<0.01) and triglycerides(r=0.874, P<0.01). The changes of PAI-1 during weight reduction period were significantly correlated with the changes of FFA(r=0.889, P<0.01) and triglycerides(r=0.869, P<0.05). The changes of both leptin and AAI-1 during weight regain period were significantly correlated with the changes of insulin(r=0.755 and 0.849, P<0.05, respectively). In summary, these results suggest that serum levels of leptin and PAI-1 were affected by weight cycling, the percentages of change were more greater than that of weight change, and rebound phenomena were occurred during weight regain period.

The Certification Authority in each country is briskly in progress to get the reliability of Electronic Commerce. One Certification Authority can not authenticate the reliability of Electronic Commerce spreading itself to the world rapidly. Therefore, Each country is constructing the base of Electronic Commerce Authority System and trying to provide cross connection with compatibility through the Cross-Authentication. This paper analysed the requirements of Cross-Authentication Mechanism on researching internationally and proposed the check-list of Cross-Authentication Model. The paper could be a guidance to organize domestic Cross-Authentication System Models.
