Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

To find out the life style of the obesity boys and girls, I conducted a survey from 922 boys and girls in the middle school students of C city in K province about their ideas about being obese, their home environment, eating habit, exercise style, and how they spend their free time. By analysing the result, I got the following conclusions. 1.Their ideas about being obese and home environment According to the survey 159 of 922 students (17.25%) were catagorized as being obese and when asked whether they think they're obese, the obesity group showed positive responses. The obesity group had high rates of having their parents as being obese, especially their mothers. 2.Eating habit They usually had more than 3 meals a day but the control group ate more frequently than the obesity group, but the obesity group ate faster. When asked, the time they eat meals and the number of times they eat snacks a day, the control group gave higher respose rate than the obesity group. Usually the control group ate more snacks before going to bed than the obesity group and the obesity group prefered to eat meat. 3.Exercise style Both groups were using their houses and playground near by their house to exercise and the control group premiered soccer as their favorite sport compared to the obesity group. 4.Leisure time Their average sleeping hour was 6-7 hours and the control group slept more than 7 hours showing difference with the obesity group.

港灣投資分石에 關한 硏究

Port investment are made mostly by public authority, are undertaken for various reasons and for different purposes depending upon the economic environment and the nature of the country's trade. And there are many roles that a port might fill, that is, stimulating growth in the economy, increasing the employment level, generating more trade, improving the balance of payments or developing certain regional areas in the country. Therefore a port authority seldom has the complete freedom to set its own policies of investment and pricing structure without prior consultation with, or approval by, the government. A straightforward calculation of financial profitability is generally not a sufficient criterion for investment choice in the case of a port. Therefore such investments should be judged not purely on the basis of financial profitability but rather on the extent to which they serve the development aims of the country. There are several methods of evaluation which could be used depending on the nature and magnitude of the port investment. The more common methods used are i) payback period ii) accounting rate of return iii) internal rate of return iv) net present value. The port's financial evaluation could take the form any one of the above methods. For economic cost - benefit analyses, however, the more relevant techniques are the latter two. And there are other related issues in investment project appraisal, that is, inflation, risk and uncertainty, priority order of investment, timing of investment. The development and continuance of the port are to be maintained by elaborate analysis and appraisal of the investment project in view of whole country.

Over the last few years, there has been a growing interest in quantitative representation of the weld pools in order to relate the processing conditions to the driving forces of the weldment produced and to use this information for the optimization of the welding process. A theoretical model offers a powerful alternative to check the physical concepts of the welding process and the effects of driving forces. To solve this problem, a 2-D thermo-fluid model were developed for determining temperature and velocity distribution for the GMA welding process.

Background:Increasing interest and use of arterial conduits is based on the better patency of left internal thoracic artery(LITA) than that of saphenous vein(SV) graft. We compared the early result of coronary artery bypass grafting(CABG) using LITA and radial artery(RA group) with CABG using LITA and SV only(SV group). Material and Method:We compared the early operative results of 6 cases in RA group with 18 cases in SV group selected from 24 cases that had CABG between January 2006 and December 2006. We analyzed each group on the preoperative risk factors and operative results. Results:We can’t find significant differences in clinical and hemodynamic characteristics before surgery. There were no statically significant difference between two groups in operative mortality and each morbidities(postoperative intraaortic balloon pump insertion, bleeding, stroke, perioperative myocardial infarction, wound dehiscence), respectively. However, the overall incidence of conventional CABG using cardiopulmonary bypass was higher in RA group compared to SV group(p=0.016). Accordingly, RA group had longer duration of ventilation time(p=0.004) and ICU stay(p=0.003) than SV group with statically significant difference between two groups in hospital stay. The graft patency on postoperative coronary angiography or computerized tomographic angiography at 7-14 days after operation in both group patients were 100%(includeing LITA, RA and SV). Conclusion:We had early good operative results in RA group and SV group. 관상동맥우회술에서 내흉동맥의 장기개통률이 복재정맥보다 우수하다는 것이 알려짐과 더불어 두 개의 내흉동맥을 이용한 군에서의 장기 임상 성적이 하나의 내흉동맥만을 이용한 군에서의 성적보다 우월하다 것이 알려지면서 최근에는 동맥이식편의 사용이 증가하고 있다1)2). 좌내흉동맥이 동맥이식편중 가장 많이 그리고 오래 전부터 사용되어왔고 그 장기 개통률이 매우 우수한 것으로 증명되면서, 이식편으로 사용 가능한 다른 동맥이식편에 대한 사용이 늘어나고 있는 추세이다. 좌내흉동맥 이외에 사용될 수 있는 동맥이식편으로는 요골동맥, 우내흉동맥, 우위망막동맥 등이 있다. 이 중 우내흉동맥은 좌내흉동맥과 같이 사용한 경우 장기 생존율이 높다는 보고도 있지만 가용길이가 짧아 이용에 한계가 있고 수술시간이 길어지며 상처 합병증과 기술적인 문제 등이 있다2). 요골동맥은 Carpentier 등3)에 의해 1970년대 초 처음 이식편으로 소개되었으나 추적 관상동맥조영술상 높은 이식편 부전으로 인해 사용이 중단되었다가 1989년 다시 소개되어 주목을 받게 되었고4), 요골동맥박리술의 기술적인 변형과 항연축제의 사용으로 요골동맥의 연축을 최소화하여 사용하면서 많은 저자들에 의해 좋은 임상 성적과 높은 개통률을 보이고 있다5-7). 본 이화여자대학교 목동병원 흉부외과에서도 요골동맥을 좌내흉동맥에 이은 두 번째 동맥이식편으로 사용하고 있는데 본 연구에서는 본원에서 경험한 요골동맥을 사용하여 시행한 관상동맥우회술의 임상 성적과 수술 후 관상동맥조영술 혹은 컴퓨터 단층 혈관조영술 결과를 분석해 보고 아울러 이를 요골동맥을 사용하지 않고 내흉동맥과 복재정맥만을 이용한 군의 성적과 비교 분석해 보았다.
