교육을 위한 BIM 적용 실험 연구 - 초등학교 설계를 중심으로 -

김용일,Kim, Yong-Il 한국교육시설학회 2014 敎育施設 Vol.21 No.5

It is evident that the education of architecture is being transformed under the influence of technological, environmental, social, and financial challenges. BIM application for design education is innovative responses that are expected to provide the high ground for the AEC industry. So the purpose of this paper introduces that application of BIM for design education of students is efficiency and effectiveness through an actual experiment by elementary school project. The results by actual experiment elaborate the role of BIM in architectural education and its appropriate place in the curriculum. Also they state that increasingly complex nature of professional world that is reliant on design teams, joint development efforts, and more complex design projects makes obsolete the designer who is trained as solo artist engaging in competitive and individual pursuits.

The problem of phlebothrombosis is an important one, not only because of its local effects, but because of the propensity for portions of the venous clot to berak off and travel back to the heart and into the pulmonary Artery. The result of pulmonary embolism, unfortunately is still as prominent a cause of death today as it was before the advant of modern advances in treatment and prevention. This paper reports a case of thrombosis of left common iliac vein left hypogastric vein and left common femoral vein, who had been bedmidden for two weeks because of left knee joint arthritis. Successfully treated with transabdominal direst venous thrombectomy and anticoagulant heparin. Authors also reviewed the references.

김용일,양관목,Kim, Yong-Il,Yang, Kwan-Mok 한국교육시설학회 2016 敎育施設 Vol.23 No.6

The objective of this paper is to introduce a curriculum for BIM design and explores characteristic of BIM Design. In order to get our approach, conducted by means of BIM throughout an actual experiment by elementary school from Architectural programming, preliminary design to design development and construction drawing. The experiment states that curriculum for BIM design requires systemically to be made in the architectural education. And also schools integrate BIM teaching early into in their curriculum. Some schools claim that BIM is often perceived as stumbling block student' creativity on account of its instant building elements. But this is not so; it all depends on how BIM is taught in the architectural education. The results state that students in the architectural school today is required to learn design by means of BIM early in the first year. Also more importantly, in order to advance the BIM design, a curriculum for BIM design is required to diversely open class in the architectural education.

Purpose: The common features of brain metastases from gastric cancer are unknown because brain metastasis is an uncommon pattern of metastasis. The purpose of this study was to investigate the clinical features of and the prognosis for patients with brain metastases after a curative resection for gastric cancer. Materials and Methods: Twenty-one (21) cases of patients with brain metastases of gastric cancer, who had been treated at the Department of Surgery, Yonsei University College of Medicine, were assessed retrospectively. Results: The mean age was $55.8\pm9.6$ years (range: $34\~70$ years), and the male-to-female ratio was 2.5 : .1. The most common neurologic symptom was headache ($38.5\%$), and no patient was free from the neurologic symptoms. The incidence of parenchymal metastasis (PM: $76.2\%$) was higher than that of leptomeningeal metastasis (LM: $19.0\%$). Patients with gastric cancer and brain metastasis showed high rates of blood and lymphatic vessel invasion (lymphatic vessel invasion: $85.7\%$; blood vessel invasion: $80.9\%$). According to Lauren's classification, the incidence of intestinal types was 14/21 ($66.7\%$), that of diffuse types was 3/21 ($14.3\%$) and that of mixed types was 4/21 ($19.0\%$). The mean interval between the gastrectomy and the diagnosis of brain metastasis was $24.7\pm4.0$ months (PM: 26.8 months; LM: 20.3 months). The median period of survival after diagnosis of brain metastasis was 2 months for paren chymal metastasis and 0 months for leptomeningeal metastasis. Conclusion:.. During a follow-up period, patients with neurologic symptoms should be suspected of having brain metastasis. Early diagnosis and treatment is the only hope to prolong survival in such patients.

불연속 변위해석법 (DDA Method)는 개별요소법의 일종으로 최근에 개발된 새로운 해석법이다. Shi(1998)는 그의 박사학위 논문에서 DDA Method를 최초로 제안하였다. 또한 이 방법에 기초한 전산 프로그램이 개발되었으며 몇 가지 적용 예들이 그의 박사학위 논문 및 여러 가지 학술논문집에 발표되었다. 지난 11년간 (1988 - 1999) 암반공학 분야에서 DDA방법의 개발 및 적용에 많은 발전이 있었다. 본 논문에서는 DDA방법의 기본이론 및 개발현황을 제시하였으며, 지반공학 분야에 있어서의 DDA방법의 적용내용을 정리하였다. The Discontinuous Deformation Analysis (DDA) method is a recently developed technique that can be classified as a DEM method. Shi (1988) first proposed the DDA method in his doctoral thesis; computer programs based on the method have been developed and some applications of the DDA method in rock mechanics have been presented in the doctoral thesis and various publications. During past 11 years (1988 - 1999), considerable progresses have been achieved in developments and applications of the DDA method in the rock mechanics. In this paper the basic theory and developments of the DDA method are presented and applications of DDA method in geotechnical engineering are reviewed.
