In some cases which are unable to replace the inserts when the depot maintenance or performance improvement of armored vehicles are carried out could have a risk of declining clamping forces by re-processing chromate. The change in the clamping forces of inserts has been investigated by applying a chromate process to hold the insert on the aluminum plate of the armored vehicle in this paper. In order to identify the effect of types and surface treatment, the breaking strength has been measured by the equivalent test item to the actual conditions. These tests would contribute the establishment of the armored vehicle production process.

장갑차의 창정비나 성능개량시 인서트를 교체할 수 없는 특수한 경우에는 크로메이트처리를 재수행함에 따라 체결력이 저하될 수 있는 리스크가 있다. 본 논문에서는 장갑차의 소재로 사용되는 알루미늄 판재에 인서트를 삽입한 채로 크로메이트를 할 경우, 인서트 체결력의 변화에 대하여 연구하였다. 판재의 표면처리와 인서트의 종류에 따른 영향성을 파악하기 위해 실제조건과 동일한 시편으로 파단강도를 측정하였다. 이러한 시험을 통해 차량 동체 제작 공정 기반을 마련하였다.

The aim of this study was to comprehensively examine the cause, actual state, region, and treatment of injury of bodybuilders in training, in order to provide basic data for the prevention of injury and effective training For this, 154 registered university bodybuilders of Korea Bodybuilding Federation were sampled randomly. And a questionnaire survey of them was conducted on the basis of the questionnaire ? ‘Research on Training Injury of Bodybuilders’ - used by in their studies. Study findings are as follows : 1st exercise time, average sets per muscle, Chi-analysis showed no significant differences in the results by age and experience mean a break, sports protective gear when Kai analysis indicated no significant differences in age-specific in most universities bodybuilding players showed little difference from those of age and experience.

The study on the treatment of cerebral palsy student with therapy riding on knee joint and shoulder joint peak torque, bilateral balance ratio / ipsilateral balance ratio studied how the impact. Spastic cerebral palsy children with were 16 week therapy riding, the analysis based basic statics, paired-samples t-test was conducted through PC using SPSS/PC version Through isokinetic strength in the knee joint peak torque/%peak torque in showed no significant difference from the right flexor, right ipsilateral balance ratio. The shoulder joint peak torque/%peak torque both no significant difference was found in the left extensor, right extensor, right flexor, right ipsilateral balance ratio. therapy riding is expected to change in strength is expected to affect the peak torque and ipsilateral balance ratio through therapy riding. Affect the therapeutic riding strength.

The purpose of this study was to examine the effects of the combined exercise on physeal plate of calcaneus, growth hormone(GH) and insulin-like growth factor-1(IGF-1) in obese adolescents. Toward this end, the study targeted 22 middle school student(BMI≥25) at W middle school in I city, who have no health problem or exercise experience. The walking exercise group performed walking program on a treadmill, 4-5 times a week (1-5week ; at the intensity of 4-560%HRmax, 6-12 week ; at the intensity of 61-70%HRmax), the resistance exercise group performed weight training in 20min(intensity; 1RM 60-70%, repetition; 10-12 rpt. per set, 3sets). The body compositions such as body weight, body fat mass and body mass index(BMI) in both the combined exercise group and the walking exercise group were significantly changed in positive, but the drop rate of the combined exercise group was larger than the walking group. The conclusions obtained from the above were as follow : physeal plate of calcaneus has presented in training group `open`(n=8), `closing`(n=3) and in control group `open`(n=4), `closing`(n=7). The changes of GH in the training group were increased after 12 weeks of exercise(<p.01), the control group has no significant difference in statistical, and the between groups comparison, has significant difference in statistical(p<.05). The changes of IGF-1 in the training group were increased after 12 weeks of exercise(p<.001), the control group has no significant difference in statistical, and the between groups comparison, has no significant difference in statistical. In conclusion, these results indicate that weight load walking training positive effects on the growth, physeal plate of calcaneus, GH and IGF-1 in obese adolescents. So we have continuous concern about training program in obese adolescents.

직류전기철도는 수송밀도가 높아 사고가 발생하였을 경우 열차지연 및 수송장애가 발생하여 사회적으로 큰 문제가 된다. 또한 직류급전회로에서 사고가 발생하였을 경우, 고장 점을 도보에 의한 현장순회에 따라 탐색하고 고장복구를 실시하고 있지만 이 방법은 시간이 많이 걸려 신속한 고장복구의 과제가 되고 있다. 이전부터 국외에서 고장점표정 장치의 연구개발이 실시되어 왔지만 현재 국내에서는 실용화되고 있지 않다. 직류급전회로의 고장점표정 방법은 중요한 기술이며, 그 필요성이 높다. 본 연구를 통하여 개발하고자 하는 방법은 급전선로의 양단 변전소의 부하전류를 이용하여 신속하고 정확하게 고장점을 표정할 수 있으며 신속한 유지보수 체계를 통해 열차지연 및 수송장애를 극복할 수 있다. Since DC electric railway has high freight density, it causes train delay and bottleneck transportation from accident and social problems from the failure effect. Also, we have restored fault point on foot when fault occurred. However, this fault localization method requires long time and it becomes obstacle to quick and smart fault restoration. Although research on fault locator has been conducted abroad in advance, this technology is not in practical use. Fault locator for DC power dispatch system is important technology with high necessity. With this developing technology from the research, fault point would be quickly and accurately localized by utilizing load current from substations beside catenary line, and train delay and bottleneck transportation would be conquered by quick maintenance system.
