In the present study, it is considered both geometrical and material nonlinearity for the analysis of the structures, and compared with the singular point position of the elastic and elasto-plastic behavior. The formulation methods use Total Lagrangian formulation. Updated Lagrangian formulation, corotational formulation. The elasto-plastic analysis apply the incremental stress-strain method, radial return algorithm, and piecewise linear method with the experimental data. The method applied go find the singular points combines the arc-length continuation method and the extended system. In the geometrical nonlinear analysis, corotational formulation is tested with the benchmark problems which include the large strain. The elasto-plastic analysis to solve the approximate solution without iteration process introduce the strain function which compared with the effective strain and the experimental data. It is compared with the singular points location of the elastic behavior and that of the elasto-plastic behavior. In the present study, it find the basically information that the difference among the formulation methods, the effect of the elastic and elasto-plastic behavior, and the position of the singular points have a affect the buckling behavior of structures.

This paper reviews rural informatization strategies for building digital Gyeongbuk by informatization of rural administration, society, industry, and life sectors. As activating policy is transformed into economizing policy for successful implementation of these strategies by utilizing rural resources, the concepts such as agri-business, precision farming, and knowledge management farming are emerging as major competitive forces for building digital Gyeongbuk in agricultural area. Also, it is necessary to practically support the linkage of rural and urban policy for reducing digital divide and encouraging diffusion of informatization mind

海運開放化에 對備한 韓國의 海運政策

寄會元 木浦海洋大學校 1994 論文集 Vol.2 No.1

By the enforcement of Uruguay Round 1993. our national policy for shipping should be changed from the protectionism of Waiver system to the Liberalism and be opened to international competition of shipping. While the shipping industries of Korea have weak point in capital and financial structure new alternatives for shipping policy should be developed to be competitive in the international shipping. To save the most important strategic cost factor in th management of ship, capital and crew cost, the following political alternatives are suggested. 1) Improve the system of ship building and purchasing. 2) Develop the subsides of shipping taxes. 3) Promote the motivation of Korean seamen.

국민과 국적

도회근 울산대학교 1999 사회과학논집 Vol.9 No.2

전통적인 국적 중심의 국민 개념은 우리나라에서 다소 편협하게 이해되어 왔고 따라서 비슷한 용어인 인민과의 잘못된 구별 등 일부 오해가 있었다. 최근에는 전통적인 국민 개념을 넘어서는 현상들도 나타나고 있다. 이 글에서는 전통적인 국민에 관한 이론들의 문제점을 지적하고 불분명하였던 부분들을 수정 내지 보완하는 논리를 제시하였다. The traditional concept of the national based on nationality is understood somewhat narrowly in Korea, so there are some misunderstandings as to a difference between the concept of the national and the people. In recent days there happen cases that we cannot explain with a traditional concept of the national. This study points out the problems of the traditional theory of the national, and suggests a theory that revises or amends uncertain elements of the traditional theory.

A Numeric analysis of one-dimensional parabolic partial differential equation has been developed using finite difference method (both explicit and implicit). This proposal method Includes the following results. 1.Some of the nonlinear equations are linearized by replacing nonlinear expressions by new variable (modified scale function). 2.Tearing of the linear subset of equation is carried out by using Gauss elimination in this subset to express all the variables as explicit linear functions of the fear variables.

Mercuric chloride, in inorganic compound, is one of the most important drugs that has been used in the argricultural drug, antisyphilitica and anticeptic, but it's not use clinical field at present time. We have studied the mechanism by examing the effect of sex-different on the mercuric chloride-induced nephrotoxicity. Blood urea nitrogen(BUN) level, urinary lactate dehydrogenase(LDH) activities of male rats give mercuric chloride significantly increased in comparison with that of the female rats. But, r-glutamyltransferase(r-GT) activity of male rats give mercuric chloride slightly increased in comparison with that of the female rats. Renal nonprotein-bound sulfhydryl, glutathione concentration of male rats significantly decreased in comparison with that of the female rats given mercuric chloride, but protein-bound sulhydryl concentration was not affected. kidney to body weight ratio of male rats subsequent increased in comparison with that of the female rats given mercuric chloride. These result suggested that nephrotoxicity of mercuric chloride in sex difference caused distal tubule necrosis on kidney.

Due to a great difficulty of permanent market with the advent of great discount stores and foreign distributors, this paper is to analyze the current situation and to present suggestions for the development of the permanent market Gumi. To achieve the objective, a field study has been conducted using the questionaires for the consumers and the interviews with the merchants of the 5 major permanent markets in Gumi area. The study is based on the pilot study by civil servants and the representatives of the merchants. Considering the problems the permanent market in Gumi it is suggested that we approach not from the viewpoint of competitive relationship but from that of mutually cooperative relationship. Then, the distribution industry will be able to enhance the life quality of citizen and develop regional community.
