This paper verifies the superiority of warming work in winter by applying the insulation gang-form to the apartment housing site and analyzes the economic feasibility of the application. According to the experimental results, the actual cost of warming work was about 52 million won less than planned, and 160 million won less than the existing average.(Note - The cost of gang form material increased from 260 million won to 310 million won after the change) As a result, the construction cost could be reduced by about 110 million won. As the costs of warming work can change depending on the number of floors, the building number, and the area of each site, it is deemed necessary to conduct a thorough review in advance at the site where the cost of warming work is to be applied. 본 논문은 단열갱폼의 공동주택현장 적용을 통해 단열갱폼 동절기 보양우수성을 확인하고, 현장 적용에 따른 경제적 타당성을 분석하고 있다. 실험결과에 따르면 실제 보양투입 비용은 사전계획대비 약 5천 2백만 원을 절감하였으며, 기존 일반갱폼대비 약 1억 6천만 원을 절감하였다.(참고 - 변경전 갱폼 자재비는 2억 6천만 원에서 변경 후 3억 1천만 원으로 약 5천만 원 증가함) 결과적으로 단열갱폼으로 변경하여 약 1.1억 원 가량의 공사비를 절감할 수 있었다. 현장마다 층수, 동수, 면적이 달라짐에 따라 보양공사비가 변경될 수 있으니 단열갱폼 적용 예정인 현장에서는 사전에 충분한 검토가 이루어져야 할 것으로 판단된다.

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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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.

Objectives : In order to investigate the efficacy and safety of the newly developed herbal medicine Jetongdan, a placebo-controlled randomized clinical trial of patients with osteoarthriotis of the knee was undertaken. Methods : Data were obtained from 80 patients with OA of the knee. After the enrollment, they were asked to answer a disease-specific questionnaire (Western Ontario and McMaster Universities (WOMAC) OA index) and analyzed with the erythrocyte sedimentation rate (ESR) in order to evaluate the efficacy of Jetongdan, and analyzed for aspartate transaminase (AST) level, alanine transminase (ALT) level, blood urea mitrogen (BUN) level, and creatinine (Cr) level in order to evaluate the safety of Jetongdan. Results : The liver function and renal function did not deteriorate after treatment with Jetongdan. Composite WOMAC score and physical function subscale was improved, but pain subscale, stiffness subscale, and ESR were not improved by Jetongdan. This was possibly because the baseline characteristics of the two groups were not homogenized after randomization. Conclusions : Jetongdan could be a promising treatment option for osteoarthritis of the knee. Further study in a larger population with appropriate severity grades is recommended.

Many of the bidge and building floor systems, including the girders and cross-beams, also behave a similar special orthotropic plates. Such plates are subject to the concentrate masses in the form of traffic loads, or the test equipments such as the accelerator in addition to their own masses. Analysis of such problems is usually very difficult. Most of the bridge slabs on girders have large aspect ratios. Finite difference method is used for this purpose, in this paper. The reuslt is compared with that of the beam theory.
