破裂性 大動脈洞瘤 : 2 例報告 Two Cases Report with Review of the Literatures
成圭寶,徐興錫,金三鉉,金近鎬 한양대학교 의과대학 1983 한양의대 학술지 Vol.3 No.2
Rupture of an aortic sinus aneurysm into a cardiac chamber results in an aortic sinus fistula causing left-to-right shunt of sudden onset. But they are susceptible to surgical treatment and cure. Therefore, accurate diagnosis preoperatively are mandatory for successful repair. Two surgically proved and repaired cases of rupture of aneurysm of sinus of Valsalva are reported with a brief review of the literatures.

정보화가 국가경제의 발전에 중요한 개념으로 등장하였다. 정보화를 추진하기 위한 계획이 예산과 얼마나 잘 연계가 되느냐를 분석하고 그 요인을 찾는 것이 이 논문의 목적이다. 정보화촉진 기본계획 16개 중 사회간접자본정보화촉진계획만을 분석의 대상으로 삼았다. 이는 종합물류정보전산망, 지능형교통시스템(ITS), 국가지리정보체계(GIS), 자동차 관련민원 행정정보망, 산업입지정보시스템, 건설사업지원통합정보시스템 등으로 나누어지는데, 대체로 계획된 예산에 많이 못 미치는 예산만이 집행 된 것으로 나타났으나, 적은 예산으로도 사업이 완성된 경우는 계획과 예산이 연계된 것으로 판단하였다. 계획과 예산의 비연계요인으로 파악한 것은 조직적 요인, 전문성의 요인, 단년도 예산회계제도의 문제, 정보화계획자체의 특성요인, 평가의 문제 등이다. 이러한 결과를 바탕으로 앞으로 계획을 입안하는데 있어서 참고자료로 삼아야 할 것이다. Information-oriented policy is very important concept lately. To be a advanced information-oriented nation, a plan and budge should be linked well. The objective of this paper is to find the degree of linkage of budget and a plan and to analyze why there is great gap between plan and budget. Among the Information accelerating basic plan and Budget, I focused just on the Social overhead capital Information accelerating plan. Most of sub projects did not have enough budget to accomplish their own tasks. But even though the projects didn't have enough budget, some of them were achieved. If so, I regard there is linkage between budget and a plan. The most important reasons of not being linked are organization problem, specialty factor, one year budget accounting system factor, the information plan itself, evaluation problem and so on. Policy makers need to heed all of these problems.
삼각형 폴리곤 곡면의 데이터 구조 및 그 응용에 관한 연구
박상근 忠州大學校 2003 한국교통대학교 논문집 Vol.38 No.4
Highly detailed geometric models are rapidly becoming commonplace in CAD/CAM, computer graphics, and other applications. Polygonal meshes are the most appropriate geometry representation for the complex models. They are flexible enough to represent any arbitrary shapes within any specific tolerance and can be directly rendered even on today's low cost PCs. In this paper, we describe the design and implementation of our face-based data structure for triangulated polygonal meshes. We start by identifying the minimal requirements, time and space efficiency, for triangular mesh data structure in the context of the geometric modeling and processing. Then we explain the details of the data structure and its design intent or features. Next, we give detailed implementations developed for atomic mesh operations with some illustrating figures and examples. Finally, we evaluate the modeling capabilities of our data structure by mesh processing applications such as smoothing, simplification, and subdivision.
VNURBS표현식에 기초한 볼륨 데이터의모델링 및 분석 기법
박상근 충주대학교 2006 한국교통대학교 논문집 Vol.41 No.-
This paper describes the volumetric data modeling and analysis methods that employ volumetric NURBS or VNURBS that represents heterogeneous objects or fields in multidimensional space. For volumetric data modeling, we formulate the construction algorithms involving the scattered data approximation and the curvilinear grid data interpolation. And then the computational algorithms are presented for the geometric and mathematical analysis of the volume data set with the VNURBS model. Finally, we apply the modeling and analysis methods to various field applications including grid generation, flow visualization, implicit surface modeling, and image morphing. Those application examples verify the usefulness and extensibility of our VNUBRS representation in the context of volume modeling and analysis.
생명보험회사의 경영효율화에 관한 소고 : 신설 K생명보험회사를 중심으로 Case in k Life Insurance Company
손성호,김건우 대구산업정보대학 1994 논문집 Vol.8 No.-
There have remarkably appeared more serious problems in profits and safety of the newly established life insurance company according to the recent change in domestic and foreign finance environment. The purpose of this study, therefor, is to suggest the following methods for effective managing the life insurance company. First, the reduction of working expenses can be accomplished by choosing a proportional allowance system of canvassers and operating branch agencies of the life insurance company on the basic of 3.3 indoor-service employees for its each agency. Second, it is required to mainly sell the middle or long-term security products so as to achieve the solvency. Third, more intensive study must be promoted on such advanced investment technologies as portfolio selection, capital assets pricing model(CAPM) and Argitrage pricing Model(APM). fininally it is not only necessay to make its underwriting more stable but also to train and educate its specialized personnel by means of both improved business of insurance contract department and strict contract selection.

The rich language of the sea which is perhaps fantastic to landmen, is the thesis for the present author to treat. It has developed through so many a country into a well-recognized and accepted hybrid languages which combine together the seamen of varied countries and produce vivid, colourful, and peculiar nautical terms in each country respectively, to say nothing of English, Definitions and derivations are given for most of the words and terms used every day at sea and particularly a great emphasis is laid on those which are most interesting and important from an etymological point of view, and those which have fallen into disuse through technological development, for example, by substitution of modern engine vessels for the ships of the older type, are also covered because of their frequent appearance in the literature of sea. Many authoritative works have been consulted in this treatise, but those which have been most helpful in search for the meanings of nautical English which are no longer in use at present, are H. mainwaring's The Sea Man's Dictionary, the first published marine dictionary in English in the 17th century, ,W. Falconer's The Sailor's Word-Book, a great treasury of nautical English, published in the 19th century, and T. Twiss' The Black Book of the Admirality' also published in the 19th century. These authors and many publications have provided the answer to vague questions, and a host of literary figures and their works, especially Shakespeares are cited for giving validity of the exact shades of meanings of those seafaring words.
