본 연구에서는 콘크리트 슬래브 궤도를 가지는 교량의 사용성 검토에 있어 단위 축하중, 단위 수직 단차, 단위 회전에 의해 발생되는 레일 지지점의 작용력에 대한 기준 값을 구하였다. 해석방법에 있어서는 레일이 탄성 스프링에 의해 연속적으로 지지되는 모델과 이산적으로 지지되는 모델이 이용되었다. 해석결과 얻어진 레일 지지점에서의 작용력은 콘크리트 궤도의 사용성 검토에서 참조되고 있는 DS 804 기준에 제시된 값과 비교되였으며, 그 결과는 잘 일치하였다. 또한, 레일 지지점의 간격과 체결장치의 강성이 레일 지지점에서의 작용력에 미치는 영향을 분석하였다.

본 연구에서는 해석의 결과 내부 지점부 보강과 외부프리스트레싱의 도입이 일반 플레이트거더교의 단면보다 단면감소의 효과가 있음을 확인하였으며 특히 외부프리스트레싱의 도입으로 얻은 솟음은 교량의 처짐을 감소시켜 사용성 측면에서 긍정적인 효과를 나타냄을 확인하였다. 해석결과를 바탕으로 하여 거더 개수 별 적용가능 단면을 도시하였으며, 거더 개수가 4개일 경우에 한하여 회귀분석을 시행해 회귀식을 제시함으로써 추후에 이와 같은 단면을 사용할 때 응력예측을 가능할 수 있게 하였다.

This study explored the relationship of children's perceived social support and locus of control to their self-esteem. Subjects were 190 5th grade children. Instruments were the revised Coopersmith Self-Esteem Inventory (1967), Dubow and Ullman's Social Support Appraisal Scale (1989), and Crandall's Intellectual Achievement Responsibility (1965). Data were analysed by t-tests and Pearson's correlations. Children with high perceived social support had higher self-esteem than children with low perceived social support. Children who attributed their success to internal factors had high self-esteem; children who attributed their success to external factors had low self-esteem. Successful children who attributed their success to external factors had low self-esteem, regardless of their social support level. Children who attributed their success to their abilities or hard work had high self-esteem only if they received high social support.

Finite element solutions are presented for the optimal design of symmetrically laminated rectangular plates with various types of internal line supports. These plates are subject to a combination of simply supported, clamped and free boundary conditions. The design objective is the maximisation of the biaxial buckling load. This is achieved by determining the fibre orientations optimally with the effects of bending-twisting coupling taken into account. The finite element method coupled with an optimisation routine is employed in analysing and optimising the laminated plate designs. The effect of internal line support type and boundary conditions on the optimal ply angles and the buckling load are numerically studied. The laminate behavior with respect to fibre orientation changes significantly in the presence of internal line supports as compared to that of a laminate where there is no internal supporting. This change in behavior has significant implications for design optimisation as the optimal values of design variables with or without internal supporting differ substantially.

Urinary disturbance is deficit in volitional control of voiding. Stroke can cause temporary or permanent urinary disturbance. The purpose of this study was to confirm the effect of Jasin-hwan on urinary disturbance as heat syndrome. This study was carried out on 3 patients with urinary disturbance caused by stroke. We measured components of IPSS (international prostate symptom score) at pre-treatment and post-treatment. After prescribing medication to the patients, symptoms improved rapidly within three weeks. These results support that Jasin-hwan is effective in reduction of urinary disturbance as heat syndrome.

본 연구는 국내의 중소업체를 대상으로 하여 ERP 도입요인과 도입성과 간에 공급사 적합성 요인이 미치는 영향에 대한 연구로, 대부분의 국내 기업에서 ERP 패키지를 도입할 경우 외부전문 업체에서 이미 개발한 패키지를 도입하는 경우가 많기 때문에 ERP 패키지의 공급사와의 적합성 요인이 ERP 도입 성과에 조절적인 역할을 하는지를 검증하고자 하였다. 연구 결과, 공급사 적합성 요인은 ERP 도입 요인과 성과 간에 조절적 역할을 하고 있는 것으로 분석되었다. 즉, 공급사 적합성 요인은 최고경영자 지원, 교육/훈련, 사용자 IT 역량, 업무 표준화/공식화 등으로 설정된 4개의 변수들과 내부성과 간에 조절적인 역할을 하는 것으로 분석되었다. 그러나 정보기술 기반구조와 내부성과 간에는 조절적인 역할을 하지 않는 것으로 분석되었다.

The purpose of this study was to investigate the relationship among personal attributions of daycare center teachers in fields, social support, and teachers' burn-out. Data were collected by 228 teachers in day care center. To examine the relationship among personal attributions of daycare center teachers in fields, social support, and teachers' burn-out, it was used the scale of 'the tendency of attributions', 'social supports', and 'burn-out'. To analyze data, Pearsons' correlation and multiple regression were used. The results of this study were as followed. First, the score of daycare center teachers' personal attributions, social support, and teachers' burn-out were higher than the mean score. Second, internal and external variables were related to burn-out factors. Third, attribute disposition were related to teachers' burn-out. As a whole, teachers were tend to be in internal attributions, which led to a tendency to show positive reactions against burn-out. Forth, social supports were related to teachers' burn-out.

Extracorporeal Membrane Oxygenation (ECMO) support to tissue oxygenation has been shown to improve survival in patients with life threatening respiratory distress syndrome or cardiac failure. Extracorporeal life support such as ECMO, including extracorporeal $CO_2$ removal ($ECCO_2R$), is used as temporary support until successful recovery of organs. A recently published multicentre randomized controlled trial, known as the CESAR (conventional ventilation or extracorporeal membrane oxygenation for severe adult respiratory failure) trial, was the first trial to demonstrate the utility of ECMO in acute respiratory distress syndrome (ARDS). During the 2009 influenza A (H1N1) pandemic, there were many reports of patients with severe ARDS related to H1N1 infection treated with ECMO. These reports revealed a high survival rate and effectiveness of ECMO. In this review, we explain the indication of ECMO clinical application, the practical types of ECMO, and complications associated with ECMO. In addition, we explain recent new ECMO technology and management of patients during ECMO support.

An internal antenna for small mobile systems is proposed to support the DVB-H system. It consists of two antenna elements, which are a folded planar monopole for DVB-H and PIFA for GSM/DCS/PCS, and a meander line and RF cable are used to increase the ground plane. Experimental results of the antenna are presented.

One of the serious long-tenn complications of diabetes mellitus is the diabetic foot lesion. Diabetic foot lesions are a major cause of morbidity, mortality, disability in patients with diabetes and frequent cause of lower-extremity amputations. The treatment of diabetic foot lesions is based on the strict control of diabetes mellitus. A patient with diabetic foot lesions was treated with Cheunhwasangamibang and improvement was seen. Results in this case support a role for Cheunhwasangamibang in controlling diabetes mellitus, and are here reported to encourage further study.
