The palace byeoljeon(別殿), the King’s non-ceremonial space, were created as a space for the king to comfortably use and for the king to do what he wanted to do. The byeoljeon housed various types of spaces and were flexible in that they could be repurposed to meet the demands of the times. Nevertheless, their characteristic as palatial building created for the King’s convenience has remained unchanged. In this study, we examine the process by which such royal spaces were created by focusing on the reconstruction of the Changdeokgung Huijeongdang during Japanese occupation period, with a view to continuity and the transformation process. The reconstruction of Huijeongdang at the time may be considered along internal and external characteristics. Internally, Huijeongdang connected the symbolism of the king’s space as the palace byeoljeon. Externally, Huijeongdang is characterized by its mixture of traditional and western style, where western style structures were housed within traditional buildings. The plans for the block of Huijeongdang also included the coexistence of traditional building, western style building, and mixture of traditional and western style building. This reflects the characteristic continuity of the byeoljeon as well as the architectural techniques of the time, manifested together within a specific spatial block.

This study includes the clinical features of diabetic patients with fascial space infections of head and neck and those of non-diabetic patients. We retrospectively studied 62 patients who were treated for fascial space infections of the head and neck, and compared the patients’ background, the aetiology of the infection, clinical variables, laboratory values, and treatment process. Statistical analyses of the differences between groups were made with Student's t test, the chi square test, and analysis of variance, as appropriate. Diabetic patients had more spaces involved, had longer hospital stays, and developed more complications. The main microorganism of diabetic group was Klebsiella pneumonia and otherwise, Streptococcus spp. was for non-diabetic group. We conclude that diabetic patients are more likely to develop complications and it is necessary to consider about dominant microorganism when using medication for diabetes patients

공간뼈대의 구조에 대하여 기하학적 비선형성이 고려될 수 있는 유한요소이론 및 해석법을 제시한다. 이를 위하여 가상일의 원리를 이용하여 대변형효과를 고려한 3차원 연소체의 평형방정식으로부터, 구속된(restrained warping)효과를 무시하고 유한한 회전각의 2차항의 효과를 포함하는 변위장을 도입하여 초기응력을 받는 공간뼈대요소의 증분평형방정식을 유도한다. 공간뼈대구조를 유한요소로 나누어 요소의 변위장을 요소변위 벡터에 관한 Hermitian다항식으로 나타내고 이를 평형방정식에 대입함으로써 탄성 및 가하학적인 강도행렬을 유도한다. 또한 updated Lagrangian co-rotational formulation에 근거하여, 증분변위로부터 강체회전변위와 순수변형성분을 분리시켜서 강체회전은 요소의 방향변화를 결정하고, 순수변형은 부재력증분을 산정하는 불평형하중 산정법을 제시한다. 공간뼈대구조의 횡-비틂좌굴 및 후좌굴 거동에 대한 예제들을 통하여 본 연구에 대한 해석결과와 문헌의 결과를 비교 검토함으로써 본 연구에서 제시된 이론 및 해석방법의 정당성을 입증한다.
