Results of the analysis of the structural behavior of axially loaded nodes in freeform structure were not fully understood due to certain difficulties, including the application of various welding and bolting types. In this study, a node of single layered freeform structure was tested to determine its structural behavior when subjected to axial loads. The tests were classified into node ball tests to evaluate the center of the node subjected to cyclic and monotonic loading. The node part tests were also conducted to evaluate the whole node subjected to monotonic loading. The test showed that the node ball is safe with the tensile force, but the node ball needs to increase its strength with the node loaded compressive force due to the additional bending moment of the node ball's asymmetric form. 프리폼 구조의 노드는 용접 및 볼트 접합 특성을 반영하는 것이 어려워 구조 성능을 해석적으로 평가하는 것에는 한계가 있다. 본 연구에서는 축하중을 받는 프리폼 구조 노드의 구조 거동을 알아보고 성능을 평가하기 위해 실험을 수행하였다. 실험은 노드 중심부의 성능을 알아보기 위한 노드 볼 실험과 노드부 전체의 내력 평가를 위한 노드부 실험으로 구분된다. 노드 볼 구조 성능 평가에서는 축력에 대한 단조가력과 반복가력 실험을 하였고 노드부 구조 성능 평가에서는 단조가력 실험을 수행하였다. 실험 결과 노드 접합부 설계가 적합하므로 실제 구조물에 인장 발생 시 노드 볼이 충분한 내력을 가지며 안전할 것으로 판단되나 압축 발생 시 노드 볼 형상의 비대칭에 따른 모멘트 발생으로 내력이 저하된 현상을 보였다.

Chronic obstructive pulmonary disease (COPD) is a frequent cause of morbidity and mortality worldwide. Cigarette smoking is considered the most important risk factor for the development of COPD, and several studies have demonstrated that inflammation in the respiratory tract is an early event in cigarette smoker and long-acting bronchodilator provides significant improvement in lung function, quality of life and symptoms in asymptomatic patients who were not previously receiving maintenance treatment. Considering pathophysiology of COPD, early diagnosis of the disease with aggressive management in early stages is the best strategy to reduce costs in COPD. However, it is inadequate to diagnose COPD as symptoms, and GOLD guideline does not recommend regular treatment in mild COPD patients. Furthermore, the reason for the underdiagnosis and delay in treatment may from medical insurance in Korea covers using regular long acting anticholinergics only in moderate or more severe patients. This article reviewed the necessity of early diagnosis, the mechanism of COPD and the significance of aggressive intervention in early COPD patients. (Korean J Med 77:415-421, 2009)

철도 및 항공 등의 교통수단은 다양한 상황에 대한 이용수요 예측이 어렵고, 개통 후 여건변화 등으로 인해 계획 시 예측된 이용 수요와 차이가 나는 경우가 발생할 수 있다. 초기 막대한 자본이 투입되어 건설되는 철도는 개통 후에도 운영비용이 지속적으로 발생하게 되므로, 철도의 안정적인 운영 및 유지관리를 위해서는 운영측면의 위험관리(Risk Management) 방안 마련 및 적용이 필요하다. 이에 본 연구에서는 현 교통수단별(KTX, 도시 철도, 항공) 위험관리의 현황 및 문제점 조사, 수요 변동에 따른 기재운영 분석 및 전문가 설문조사(AHP) 등을 통해 KTX 개통 후 열차이용객 변화에 따른 운영측면의 실질적인 위험관리방안을 제시하고자 한다. Means of transport such as railway and aviation are difficult to predict demand forecasting because of a variety of situations. And due to changes in circumstances after the opening, the demand can be changed compared with the previous forecasting. The initial capital for railway construction is so huge but operating cost is still continuously increased after the opening. So for the reliable operation and maintenance of railway, it is necessary to make and apply for risk management. In this study, we are going to suggest the practical risk management by the change of the number of passengers after opening KTX train. The using methods are investigation of the current situation and problem of the risk management about the current transportations such as KTX and metro and aircraft, analysis of operating matters by changing the demand, and method of Analytic Hierarchy Process (AHP).

Transfusion related acute lung injury (TRALI) is a serious, potentially life-threatening complication of transfusion therapy that is sometimes under diagnosed and under reported. Patients with TRALI present with dyspnea/respiratory distress and fever. The symptoms, signs and chest radiological findings in TRALI are similar to transfusion associated circulatory overload, which makes it is difficult to distinguish it from circulatory overload. Although the mortality rate in cases of TRALI is relatively low, TRALI is the third most common cause of fatal transfusion reactions next to ABO blood type incompatibility and hepatitis. Mild-to-moderate cases of TRALI may be misdiagnosed as volume overload. Recently, we encountered two cases where the patients suffered from dyspnea and fever after a transfusion. and review of the relevant literature. (Tuberc Respir Dis 2006; 61: 473-478)
