According to the literary study on catheterization of bladder in one case of patient with C.V.A. who was treated by supra pubic catheterization, the results were as follows. 1. If not immediately treat ischuria, emergency disease, very great danger to life can happen by loss of kidney function. So we must treat ischuria instantly by consideration of treatment from the factor. 2. Catheterization of bladder generally acted in emergency room, is emergency treatment only in the lower part of urethral obstruction. 3. Catheterization of bladder was put on record in Son Saimiao's Qianjinyaofang, which is the first book on it. It had been developed by Luo Qianyi, Zhang Jiepin, and Wang Dao. 4. Ancient times, an urethral catheter was made of green onion leaf, pig bladder, goose feather and so on. 5. Nelaton is catheterization of bladder in functional or momentary ischuria. Indwelling catheterization is treatment keeping in urethral canal for a long time. 6. Supra pubic catheterization is a surgical operating catheterization when urethral catheterization is impossible, is very easy and can decrease risk of infection. 7. After catheterization, for decreasing risk of the infection, a complication of catheterization, it is must be taken precedence, ascetic treatment, constantly management and sterilization, anti-biotic medication. 8. At times, increasing patient of emergency disease, as C.V.A etc., the needing of catheterization of bladder is increasing also for preventing infection and bed sore by ischuria and incontinence of urine. Therefore a specialty knowledge and skill about it is necessary.

This research presents a Reliability-Based Topology Optimization (RBTO) using Bi-directional Evolutionary Structural Optimization (BESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. Deterministic Topology Optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, RBTO involves evaluation of probabilistic constraints, which can be done in two different ways, the reliability index approach (RIA) and the performance measure approach (PMA). The reliability index approach (RIA) and the performance measure approach (PMA) are adopted to evaluate the probabilistic constraints. In order to apply the BESO method to the RBTO, sensitivity number is defined as the change in the reliability index due to the addition or the removal of the ith element. In the BESO, a mesh-independency filter using nodal variables is used to remove the checkerboard patterns. The optimal topologies of RIA and PMA are obtained very similarly. It is shown that RBTO based on BESO can be effectively applied from the presented examples.

This study explores how the tension between global integration and local responsiveness affects the dimensions and determinants of international human resource strategy. The effects of interorganizational interdependencies, competitive strategies and cultural differences, ownership on the two different dimensions of IHR strategy were studied using a sample of 53 MNCs subsidiaries operating in Korea. The findings for global integration suggest that when a subsidiary is highly dependent on the parent to provide crucial resources. And the findings for local responsiveness suggest that when a subsidiary is highly dependent on the host to provide crucial resources and institution. As for the hypothesized interaction shows a negative, significant relationship between a subsidiary's dependence on host institution and ownership and its localization(b=0.0211, p=0.05). Also between a subsidiary's dependence on host resource and ownership and its localization(b=-0.0113, p=0.1). Accordingly, these insights should prove to be useful to researchers and international human resource managers interested in the formulation and implementation of international human resource strategies.

This paper aims to introduce the heuristic systematic mode and propose some implications that should be actively utilized in understanding tourist behavior. Heuristic systematic model is a theory that drawing conclusions through an intuitive way of thinking , rather than in the absence of a clear clue status on the basis of reasonable thinking. In everyday situations, we have many cases that the decision through an intuitive way of thinking than rational thinking through a decision . Tourist behavior in many cases decisions through intuitive thinking like this. But look came ahead of the leading tourism research through action research to understand the rational way of thinking is understood to consist of continuous action by the irrational mindset is not carried. In other words, in order to understand the irrational behavior by thinking in understanding the tourism action it should be to understand the heuristic systematic model prior , and should use them actively to understand the tourism behavior.

It is difficult to explain the magnetic phase transition with classical physics in Curie temperature. We studied qualitatively with the well known Ising model in statistical mechanics. We simulated systems of finite size by Monte Carlo methods with Metropolis algorithm. Thus we could estimate the values of quantities such as the magnetization(m) per spin the specific heat(c) per spin the magnetic susceptibility(χ) per spin, and the mean energy per spin compare with the numerical values in infinitive size. The quantities of c, m, χ, e varied rapidly within 2.3∼2.4 temperature at J/k units. Those values show that the critical temperature can be within the range. The hysteresis loop was obtained with this model.

본 연구는 불화나트륨과 자일리톨 성분으로 구성된 구강 청정용 저작성 정제(덴포정, 하미즐, 부천, 경기)가 교정치료 중인 환자의 구강위생 상태에 미치는 영향을 알아보기 위해 시행되었다. 교정치료 중인 18세 이상의 성인 환자 30명을 대상으로 약제 상요 전, 2주 후, 4주 후에 피험자의 상악과 하악 전치 부위 및 구치 부위에서 각각 치은 지수, 치은 출혈 지수, 치태 지수를 측정하여 다음과 같은 결과를 얻었다. 1. 상하악 전치부와 구치부 모두에서 치태 지수가 약제 사용 전에 비해 사용 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 또한, 적용 2주 후와 4주 후의 지수를 비교하였을 때 4주 후에 좀 더 개선된 경향을 보였으나, 통계적 유의성은 나타나지 않았다(p<0.05). 2. 치은 지수, 치은 출혈 지수도 상하악 전치부와 구치부 모두에서 적용 전에 비하여 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 적용 2주 후와 4주 후의 지수의 비교 검증에서 통계학적으로 유의할 만한 차이가 보이지 않아 구강위생 상태의 개선이 계속 유지됨을 보였다. 본 연구의 결과는 치태 지수, 치은 지수, 치은 출혈 지수가 실험 정제 적용 후에 감소하여 구강위생 상태가 개선되었음을 보였다. 이러한 결과를 통해 덴포정을 교정치료 중인 환자에서 부가적으로 사용하였을 경우 치주조직의 건강을 증진시키는데 도움을 줄 수 있으리라고 생각된다. The aim of this study was to evaluate the effect a chewable tablet containing sodium fluoride and xylitol (DenPo, Hamizzle, Bucheon, Kyungki) on the oral hygiene state in the orthodontic patients. The subjects consisted of 30 adult orthodontic patients, who have worn the fixed orthodontic appliance at least 6 months. They were instructed to use the tablet forth a day. Gingival index (GI), plaque index (PI), and sulcus bleeding index (SBI) of upper and lower anterior and posterior regions were measured before using the tablet (TO), 2 weeks after using the tablet (T1), and 4 weeks after using the tablet (T2). The data were analyzed with Wilcoxon signed ranks tests. The results were as follows ; 1. PI was decreased significantly in the T1 and T2 stage compared with TO stage in the both anterior and posterior regions (p<0.05). Although PI was decreased in the T2 stage compared with T1, there was not statistical significance(p>0.05). 2. GI and SBI showed similar results compared with PL. In the T1 and T2 stage, there was statistically significant decrease in the GI and SBI (p<0.05). This study showed that the DenPo tablet could be used as an adjunct to improve oral hygiene in the orthodontic patients. The decrease of the indices may suggest that DenPo tablet could be effective in the plaque removal and prevention of gingival inflammation in the orthodontic patients.

The present study was carried out to investigate the effects of physical training on glucose tolerance, insulin secretion, insulin sensitivity and insulin binding to erythrocytes in non-insulin dependent diabetic subjects(NIDDM) with fasting hyperglycemia and low insulin response during OGTT. The subjects were separated into two groups. One was diabetics treated with mild caloric restriction and physical training(Training group, n=18), the other was diabetics followed with mild caloric restriction alone(Sedentary group, n=20). Physical training consisted of 3-5 days weekly, 30 minutes sessions, with jogging corresponding to 40-50%VO₂max. Insulin sensitivity was determined by euglycemic insulin clamp technique. Following results were obtained. 1) Oral glucose tolerance was improved after 2 month training and remained unchanged thereafter in the training group. It was also improved in the sedentary group, however, the degree of the improvement in OGTT at 6 month treatment was more pronounced in the training group than in the sedentary group. 2) Amelioration of plasma insulin response during OGTT was observed after 6 months of treatment in the training group only. 3) After 2 months of treatment, glucose metabolic clearance rate(MCR) increased from 4.1㎖/㎏/min to 6.7㎖/㎏/min in the training group, but no change of MCR occurred in the sedentary group. 4) No significant changes in insulin binding to insulin receptors were observed in both the training and the sedentary groups. In conclusion, physical training improves glucose tolerance through an enhancement of insulin sensitivity and further insulin secretion in NIDDM with fasting hyperglycemia. It is useful as an adjunctive to diet in the treatment of NIDDM.

As developing the technology in industry, the materials with superior grade of stiffiness and lightness are required, and hence the higher fatigue strength characteristics are necessary. Thus, the non-traditional machining to increase fatigue strength is becoming influential as very important technology. Considering environmental problem, the shot peening process is selected as a good process to increase fatigue strength. But the data related to shot peening process are not enough in this country. Shot peening process is essential to ensure repeatability and uniformity on a part to part and lot to lot basis, while conforming to the applicable specifications. The shot material, size, shape and hardness as well as velocity and impact angle must be controlled to provide consistency in peening results. In order to effectively control the shot peening process, parameters must be addressed in the following order, such as media control, coverage control, intensity control, equipment control and so on.
