The application of CT with basis on 3 dimensional-reconstruction is getting more widely practiced. With the data obtained from cone-beam computed tomography(CBCT), not only the diagnosis of the patient with skeletal abnormality but also the virtual simulation of the orthognathic surgery were performed and its application would be popular in orthodontic field. We reported a case, a 19-year old man who was diagnosed mandibular prognathism and required orthognatic surgery. In this case, the virtual orthognathic surgery was simulated and surgical wafer was fabricated by using CBCT data. That wafer was applied the actual orthognathic surgery. After preoperative orthodontic treatment, we prepared surgery as follows. : (l)Acquisition of 3D image data, (2)Reconstruction of 3-dimensional virtual model, (3)Virtual model surgery, (4)Extraction of stere-olithographic image, (5)Check-up for occlusal interference, (6)Fabrication of surgical stent by stereolithography. Bilateral sagittal split ramus osteotomy was operated and used stereolithographic surgical stent. 1 month later, we superimposed CBCT datas of virtual surgery and that of actual surgery, and then compared the result. CT data's application for othognathic surgery yielded satisfactory outcomes.

Today`s distribution market has many structures such as department stores, large discount stores, traditional markets, and internet shopping malls, and the choice variety of the consumers` purchase behavior increased. For this, this study conducted research about consumer choice criteria about department stores among many distribution market structures and consumer satisfaction in Yong-In and Bun-Dang area. The degree of importance about choice criteria for department stores in general was analyzed, and for the degree of importance items, degree of preference about the actual department stores in Yong-In and Bun-Dang area was additionally analyzed. The selection of factors for department store choice criteria was ultimately done by consulting with researchers of the previous studies and distribution specialists, and the survey was conducted from an outside survey institute, and the relative importance was evaluated by AHP method. Also, additional research was conducted on the actual consumer preference of department stores located in Bun-Dang and Yong-In area about each choice criteria item. From the analysis results, the factors that are considered in priority in choosing a department stores and actual preference of department stores were analyzed, and the consumer characteristics and new perception standard were identified.

영동선 동백산-도계간 장대터널 시공사례 연구

김용일,윤영훈,조상국,양종화,이내용,Kim, Yong-Il,Yoon, Young-Hoon,Cho, Sang-Kook,Yang, Jong-Hwa,Lee, Nai-Yong 한국터널지하공간학회 2002 터널기술 Vol.4 No.2

본 논문은 영동선 동백산역에서 도계역사이를 연결하는 장대터널 (솔안터널)의 시공사례에 대한 연구결과를 제시하였다. 본 터널은 완공시 길이 16.2Km로 국내최장터널이 된다. 본 터널 현장은 단층, 공동 및 함탄층으로 구성된 지질학적으로 복잡한 지역에 위치한다. 2번사갱 굴착을 위하여 사전에 전기비저항탐사 및 지하레이다탐사 등의 지구물리학적인 탐사방법이 단층, 공동 및 함탄층을 사전에 찾아내는데 활용되었으며, 이 방법은 상당한성과가 있었다. 이 물리탐사결과 및 현지 시추자료는 터널 보강설계를 개선하기 위한 자료로 활용되었다. 강관다단 그라우팅 방법은 단층 및 공동이 발달한 지역에서 좋은 보강 및 그라우팅효과를 발휘함이 입증되었다. 함탄층에서는 스웰렉스 록볼트와 공내 몰탈 그라우팅을 병행한 방법이 효과적임이 확인되었다. This paper presents a case study on the construction of a long tunnel named as "Solan tunnel", which connects between Mt. Dongbaek station and Dokye station in the Youngdong Railroad. The tunnel will be the longest tunnel with length of 16.4 km in Korea when completed. The tunnel site is located in a complex geological region with faults, cavities and coal measures. In construction of adit No. 2, geophysical investigation methods such as electrical resistivity method and GPR(Ground Penetration Radar) were used to detect faults, cavities and coal measures in advance with some success. The geophysical investigation results and in-situ boring data were used as feedback to improve tunnel reinforcement design. Also, the tube umbrellas of grouted steel pipes were found to have a good reinforcement and grouting effects in zones of faults, cavities. In zones of coal measures, swellex rockbolts with mortar grouting were verified as successful.

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.

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.

Results of experiments conducted in university-based design studio suggests that Building information Modeling invites the adoption of a dramatically different design process, traditional design process and BIM-aided design process. Experiment method is used the actual experiment by students. In contrast to traditional design process rooted in successive refinement of abstractions and dependence on tacit knowledge, the studio BIM-aided design process depends on a complete and comprehensive date base and alterative solutions by complete analysis for helping choice of finial result. BIM viewed as provocateur of design education provides great potential for the critical analysis of how architectural design is taught. The results reflect new ways of teaching and addressing BIM methods and process in the design studio project.

김용일,Kim, Yong Il 한국터널지하공간학회 1999 자연, 터널 그리고 지하공간 Vol.1 No.2

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.
