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.

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.

지형정보시스템에 의한 환경영향평가에 관한 연구

김용일,김형태,Kim, Yong Il,Kim, Hyung Tae 대한토목학회 1992 대한토목학회논문집 Vol.12 No.3

날로 심각해지고 있는 환경문제에 대응하기 위하여 정부는 1979년 환경영향평가제도(EIA)를 시행하고 있다. 이에 따라 환경오염은 여느 때보다 엄격히 규제되고 있으나 오염현상은 더욱 복잡해져서 그 피해상황도 여러가지 양상을 띄고 있다. 본 연구에서는 환경영향평가의 효율적인 목적달성을 위해, 체계적이고 과학적인 접근방법을 모색해 보고자 하였다. 즉, 지형정보시스템 (GIS)과 원격탐사(RS) 기법을 환경영향평가제도에 적용시키고자 하였으며, 그 대상지역으로서 관광단지 개발이 예정된 전남 화원 지역을 선정하여 여러가지 가정에 입각한 평가를 실시해 보았다. 평가내용으로서는 토공량계산, 토지이용모델작성, 사면방위도제작, 사면안정성평가, 가용부지추출 등이 연구내용에 포함되었다. 결과적으로 대상지역의 현황을 효율적으로 정확히 파악하고, 환경파괴를 최소한으로 하는 개발계획의 수립을 위한 자료를 제공함에 있어 지형정보시스템의 적용은 필수적이라 하겠다. EIA(Environmental Impact Assessment) was introduced in 1979 by our gorvernment to cope with serious environmental problems. Recently environmental pollution has been controlled severely than ever because pollution phenomena became more comlpicated and arrcordingly the damage more terrible. For the EIA system to achieve its goal effectively, systematic and scientific approach should be found out. For this reason the techniqes such as GIS(Geographic Information System) and RS(Remote Sensing) come to front strongly. The purpose of this paper is to investigate the application techniqes of GIS and RS to the EIA system. Haw-Won Myen, Hae-Nam Gun, Chun-Nam and its related area, which will be developed to be a sightseeing area, were selected as the study area. Applications of GIS resulted some important outcome such as earthwork calculations, landuse models, aspect maps, stability of slanting surfaces, elevation models, estimation of real estates, etc. GIS applied EIA proved to be very useful for the project managers and planners to plan, evaluate, judge the enviormental problems.

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.

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.

불연속변위해석법의 기본이론 및 개발현황

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.
