With competitions for the building height at all parts of the world, the necessity for new structural system efficiently-resisting lateral loads is being increased. Especially, for super high-rise building, new considerations for lateral load resisting system is required to control lateral displacement which is increased by 4-square of building height. In this study, split cores are applied as a lateral load resisting system, and structural behaviors are studied by 3-D finite element analyses. The point load is laterally applied to top of 3-D model of building structures with single or dual cores and mega columns, and then the structural efficiencies are analyzed with the lateral displacements of top of buildings. The structural capabilities of single and dual core systems are compared, and the effects of various parameters - number of outriggers in a building, number of stories of a outrigger, sectional area ratios of columns and walls, and building height - on structural behaviors of high-rise building are analyzed. Also, through simple examples of lateral load resisting designs, the material quantities are compared. Finally, based on analysis results with various parameters, the guidelines for the efficient structural system with dual cores are presented.

In many RC high-rise buildings, a shear wall and outrigger system is used as a lateral-load resisting system. In a shear wall and outrigger system, to minimize the additional forces in outriggers by differential shortening of adjacent vertical members, a delayed-joint construction method of outriggers is frequently applied. But, in construction stages with unconnected joints of outriggers, a design-intended lateral road resisting system is incomplete and structural performances for lateral loads may be weakened. In this study, to analyze effects of delayed-joint outrigger construction on structural performances of RC high-rise building under construction, a tower-typed residential complex building with 60 floors is selected as a sample model, and numerical analyses are performed. At several construction stages, appropriate construction load conditions and numerical analysis assumptions are applied, and numerical results present comparisons of structural performances including fundamental shapes and periods, lateral behaviors, and member design strength ratios. Also, this study can be used as guidelines of design loads and structural analysis schemes for checking the safety of RC high-rise buildings under construction.

We observed the histopathologic findings of 21 biopsed materials those initial clinical impression was suspected as granuloma pyogenicum. Also we compared the cange in the number of mast cells in the lesion of the granuloma pyogenicum with those in the normal appearing skin by Giemsa stain, and the stainability of mucopolysaccharides in the stromal edema of granuloma pyogenicum lesion with that in the normal appearing skin by Alcian blue-PAS stain. The results were as fallows: The various microscopic diagnoses made in 8 cases, which was clinically granuloma pyogenicurn. These 8 cases were granulation tissue(3), subungual exostosis(1), dermatofibrorna(1), sebaceous epithelioma(l), liporna with granulation tissue(1), and malignant melanoma(1). 2. The number of mast cells in the granuloma pyogenicum lesion were increased (p<0.01), especially in the lesion which showed marked capillary endothelial proliferation, and the amount of mucopolysaccharides was increased in the stromal edema of the granuloma pyogenicum lesion.

실제 운동수행을 할 때와 머릿속으로 운동수행 장면을 시연하는 이미지트레이닝 할 때의 사건유발전위(ERP)와 대뇌 네트워킹(BMP)의 유사성을 규명하게 된다면 향후 선수 개인의 이미지트레이닝 적용에 있어 숙련 단계와 그에 따른 효과적인 적용 방법을 개발하여 스포츠현장에 제공하는 데 있다. 이러한 연구목적을 달성하고자 배드민턴 선수 35명을 대상으로 배드민턴 기술 중 신체적 움직임이 가장 적고 폐쇄성 기술 특성의 서비스(service)로 셔틀콕과 라켓을 든 상태에서 서비스를 넣기 위한 준비자세에서 서비스를 넣기 위해 라켓이 움직이기 시작하는 직전까지의 뇌파 신호를 추출하여 분석에 사용하였다. 뇌파 신호 수집은 락싸(Laxtha)사의 QEEG-64FX 뇌파장비와 2ch Flexible Ag-AgCl 건식 뇌파캡을 사용하여 양쪽 귓불과 목 뒷부위에 참조전극(reference electrode)를 부착하고 전두엽(F3, F4), 두정엽(P3, P4), 운동영역(C3, C4), 후두엽(O1, O2)에 해당 부위에서의 뇌파 활성 데이터를 수집하였다. 배드민턴의 서비스 기술에 대한 실제 운동수행과 이미지트레이닝 시의 사건유발전위(ERP) P300의 잠재기와 진폭의 유사성과 대뇌 네트워킹을 검증하고자 자료분석 방법으로 SPSS 통계 프로그램을 사용하여 독립 t 검정을 실시하였다. 분석결과에 대한 유의성 기준은 p<.05이다. 뇌파신호를 활용하여 실제 운동수행과 이미지트레이닝의 차이를 검증한 결과, 동일한 운동과제에 대한 뇌파신호의 반응 패턴에서 시각적 정보처리를 담당하는 후두엽에서의 진폭과 잠재기를 제외한 다른 영역에서의 뇌파신호 진폭과 잠재기가 유사한 것으로 나타난것과 함께 대뇌 네트워킹에서도 운동영역과 후두엽에서의 차이를 제외한 모든 대뇌 영역 간 유사한 네트워킹 활성을 보이는 것을 확인하였다. If the similarity between the event trigger potential (ERP) and the cerebral networking (BMP) during actual exercise performance and image training that demonstrates the exercise performance scene in the head is identified, the proficiency level and It is to develop an effective application method accordingly and provide it to the sports field. To achieve this study purpose, 35 badminton players were subjected to the least physical movement among badminton techniques and a racquet was used to put the service in the ready position to put the service while holding the shuttlecock and racket. EEG signals up to just before the start of movement were extracted and used for analysis. EEG signal collection was performed using Laxtha’s QEEG-64FX EEG and a 32ch Flexible Ag-AgCl dry EEG cap, with reference electrodes attached to both earlobes and the back of the neck, and the frontal (F3, F4) and parietal lobes (P3, P4), motor areas (C3, C4), and occipital lobe (O1, O2) were collected EEG activity data in the corresponding area. In order to verify the similarity of the latency and amplitude of event related potential P300 and cerebral networking during image training and actual exercise performance for badminton service skills, an independent t test was conducted using the SPSS statistical program as a data analysis method. The significance standard for analysis results is p<.05. As a result of verifying the difference between actual exercise performance and image training using EEG signals, the amplitude of EEG signals in the occipital lobe, which is responsible for visual information processing, in response patterns of EEG signals to the same exercise task, and EEG signal amplitudes in areas other than the latent phase and latent period were found to be similar. In addition, it was confirmed that in cerebral networking, similar networking activity was shown between all cerebral regions except for differences in the motor region and the occipital lobe.

Background/Aims: Crohn`s disease is a chronic inflammatory bowel disease. Stricture is a very important indication for surgical intervention as strictures can lead to intestinal obstruction. Strictures can be divided into inflammatory and fibrous strictures. Intestinal obstruction due to inflammatory stricture is expected to be resolved with medical treatment. However, factors that can predict the response to medical treatments are unknown. In the present study, we aimed to identify the factors that can predict the response to medical treatments in Crohn`s disease patients with intestinal obstruction. Methods: Data were collected by retrospectively reviewing the medical records of patients with Crohn`s disease who visited the emergency department at Samsung Medical Center in Seoul from January 1, 2000 to December 31, 2010 because of intestinal obstruction. Based on the response to medical treatments, we classified the patients as responders and non-responders and compared the clinical, biochemical, and radiological findings of the two groups. Results: A total of 39 patients were enrolled. Twenty-nine patients responded to medical treatments whereas 10 patients did not. Significant differences were observed between the two groups in terms of vomiting and duration of disease before the development of obstruction. Conclusions: Patients who responded to the medical treatments exhibited a higher incidence of vomiting and longer duration of disease before the development of obstruction. However, further prospective studies are needed to identify the factors that can predict the response to medical treatments. (Korean J Gastroenterol 2013;62:213-218)
