Project Financing (PF) is a financing method, executed based upon the projected profitability from a project itself instead of relying on the credit rating of project sponsors or any type of collateral. However, most financial institutions of Korea lacks the long term profitability assessment capability, and they prefer to acquire credit reinforcement from the construction companies in the form of the guarantor or debt argument commitments. As a result, PF contingent liabilities as an indirect debt, are burdened to the construction companies. Even though the PF contingent liabilities are not supposed to be part of the financial statements, they became a mandatory disclosure items since 2009. In this study, PF contingent liabilities were studied to indicate how they were correlated with construction firms' financial ratios. Construction firms were grouped by their credit rating and each group was compared in order to analyze PF contingent liabilities' impact on the financial condition of the company in terms of liquidity, liability, and stability.

본 연구에서는 DUPIC 핵연료 주기개발이 상업화 됨을 전재로 하였을때 핵연료 제조 공정에 대하여 핵임계 해석을 수행하였다. 계산 과정은 PWR 핵연료봉을 해체하는 공정과 분말을 취급하는 공정으로 나누었으며, 이중 우발성의 원리를 기초하여 가상 사고 조건을 고려하였다. 핵임계 해석의 결과, DUPIC 핵연료 제조 공정에서는 특별한 가상조건을 제외하고는 핵임계의 위험은 없는 것으로 나타났다.

Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the $6^{th}$ rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.

건물의 고도화 및 최첨단 공조시스템에 있어서 공기 조화기는 가장 핵심적인 장비로서 고장의 전도는 비교적 단순하나 요소기술의 적용, 운전, 유지관리에서 소홀하게 되 면 환경 업무의 저하와 생산성이 낮아지고 막대한 비용을 초래하기도 한다 . 고장은 설비시스템과 공조기의 사용기간이 길어짐에 따라 마모, 피로 등의 물리적 성능열화가 진행되며 이러한 물리적 열화가 최종적으로 나타나는 현상이 고장이다. 고장의 시간적 변화에는 초기고장, 우발고장, 마모고장으로 분류되며 초기고장은 시스템의 불안정에 따른 원인으로 시운전시에 자주 발생하고 정상적인 운전시에 발생되는 우발고장이 기간이 지나면 마모 고장기에 도달하게되며 이때는 부품의 한계수명과 마모등의 원인으로 고장률이 급격히 증가된다 따라서 본문에서는 공조시스템의 공기조차기의 팬과 펌프 기기의 고장원인을 살펴보고 이에 대한 고장을 신속하게 감시할 수 있는 방안을 일반적일 고찰을 통해 체계적이고 종합적인 대응방안을 소개하여 불필요한 보수비용의 발생과 생산성 저하를 방지하고 내구년수를 증가할 수 있는 신기술의 일부분을 소개하고자 한다.

Because of the difference between the actual and computed eccentricity of buildings, symmetrical buildings will be affected by torsion. In provisions, accidental eccentricity is intended to cover the effect of several factors, such as unfavorable distributions of dead- and live-load masses and the rotational component of ground motion about a vertical axis. The torsional amplification factor is introduced to reduce the vulnerability of torsionally imbalanced buildings. The effect of the torsional amplification factor is observed for a symmetric rectangular building with various aspect ratios, where the seismic-force-resisting elements are positioned at a variable distance from the geometrical center in each direction. For verifying the torsional amplification factor in provisions, nonlinear reinforced concrete models with various eccentricities and aspect ratios are used in rock. The difference between the maximum displacements of the flexible edge obtained between using nonlinear static and time-history analysis is very small but the difference between the maximum torsional angles is large.

In this study, we investigated the recognition of the first aid of guard major college students are trained to deal well and flexibly to the situation of unforeseen circumstances, you are trying to present the teaching methods and effective importance of first aid. Analysis of data collected in this study is as follows: The results obtained using the statistical program SPSS18.0. First, education has not been done properly, there is no difference between the average score of people who did not receive the people who received the fact of first aid veritable we are specialized in, the second education systematic is needed, training of first aid has not been properly implemented, problems of education there were many. Third, because there is no difference in the level of knowledge by training institutions of first aid, the places where there is training of first aid, there is no effect on the knowledge level. Therefore, it can be the need training first aid practical to enhance the ability to proactively address the situation of contingencies.

Accidental high epidural block is a rare but serious complication. It can result from many factors, which include the volume and concentration of drug, posture, puncture site, age, pregnancy or intra-abdominal mass, and patients' height and weight. We had a case of accidental high epidural block recently. This is a case report which was confirmed by an epiduragram. A healthy 50-year-old woman with a huge uterine myoma was scheduled for a total abdominal hysterectomy under continous epidural analgesia. Epidural catheterization was carried out smoothly. However, an unexpected hypotension was noticed after an epidural injection of 2% lidocaine 25 ml. Thereafter, the patient was intubated and her respiration was controlled during the operation. Using the 5mg of ephedrine, her blood pressure and pulse were well maintained. The scheduled operation was carried out for one hour uneventfully, but after the operation, she felt paresthesia on her hands in the recovery room. To differentiate between the high epidural and the subdural blocks. We injected 5 ml of a water soluble Niopam 300 through the catheter postoperatively. It was observed on the epiduragram that the catheter was placed in the epidural space. It was suggested that the high epidural block was induced from the widespread diffusion through the narrowed epidural space due to the engorgement of the epidural venous plexus by the patient's huge uterine myoma.

Purpose : Childhood accidents have been increasing recently. Accidents rank as the leading cause of childhood mortality and morbidity. We performed this study to evaluate the causes of childhood accidents. Methods : The authors analysed retrospectively the medical records of 6,410 cases of childhood accidental injuries who visited the emergency room of Asan Medical Center from January 1990 to December 1999. Results : The most common type of accidents was trauma which accounted for 5,038 cases of the total accidents, followed by falls, burns, foreign body aspiration, and poisoning. The most common age of foreign body aspiration was under two years old and the male to female ratio was 2 to 1. The most common site of foreign body aspiration was the esophagus and the stomach, followed by the respiratory tract. In airways, the right and left main bronchus were the most common site for foreign body aspiration and were accompanied by the highest mortality. The most common foreign body in the gastrointestinal tract and respiratory tract were coins and peanuts, respectively. Conclusion : The most common cause of accidents was trauma, followed by falls, burns, foreign body aspiration, and poisoning. The incidence of foreign body aspiration and poisoning is increasing in infants. In cases of foreign bodies in airways, proper management is needed because of the high mortality rate.
