General purpose programs are essential elements for the computerization of structural analysis. This paper is associated with actual formulation of such programs by matrix analysis. The basic theory of matrix analysis for skeletal structures, its implementation and techniques for developing efficient programs are discussed in this paper. Any shape of skeletal structure can be included in a single program for space frames. But in order to economize computing time and computer memory space, it is desirable to develop and operate seperate programs specialized into four categories; truss, planar frame, grid and space frame. As for general purpose programs, simplicity of input format and flexibility of output format should be duly considered. Compaction and solution of system equations are the most important aspects in computer programming of matrix analysis, and worth further study for more efficient computerization.

This paper is a study for the computerization program of incoming and outgoing processes of a number of parts and a great amount of material for producing products in flood industry, which was required by a medium-sized company located at Cheon-An. The program consists of four databases, one main form, seventeen subforms, and eight report forms. Concretely speaking, the four databases are prepared for products, semi-products, material, and reports, and the seventeen subforms are those for current inventory, used quantity, safty stock, product specification, etc. With the program, users can be helped and save manpower, time and cost in incoming and outgoing processes of parts and material for producing products and in their real time operation and decision-making.

최근 들어 행정기관의 정보 기술 분야에 막대한 예산이 투입되면서 공공부문의 정보화가 빠른 속도로 전개되고 있다. 이러한 공공부문의 정보화를 위한 노력들이 과연 어떤 효과를 가져오고 있는지에 대한 연구의 필요성이 제기된다. 본 연구에서는 성과측정을 위한 척도로서 행정기관 IT생산성 지수를 산출하기 위한 지표를 선정하고 그에 따라 지수를 산정하여 이를 연도별로 비교해 보고자 한다. 행정의 업무효율성이라는 측면에서 IT생산성은 3년 동안 꾸준히 증가추세를 보인 반면, 대민서비스를 통한 고객만족도를 생산성개념에 추가시켰을 때는 2001년의 생산성지수가 전년도에 비해 약간 저하되었으며, 2002년에는 증가추세를 나타내고 있다.

The computerization works and environment have been changed from simple transaction and data process request to system connection request, from data computerization to application work automation and process computerization through IT development and Internet spread. Recently, BPM(Business Process Management) concept has been widely propagated. It is expanding interest of business subject. Korea Railroad is operating train operation management system through 5 regional headquarters and organizations under the influence of each regional headquarter. But integrated operation and management of communication each department, work flow management and resources of depot equipment and materials have to need a lot of effort and time in huge organization as Korea Railroad. Therefore, this article realized Web Based BPM Group Ware. This article will define Korea Railroad organization and business process in using this Group Ware. And it will introduce Korea Railroad computer manage system of this Group Ware and efficient Korea Railroad Business Process through modeling and operating department work and resources management in Korea Railroad.

The tedious work, connected to the altitude correction, the computation of altitudes and aximuths and the plotting of the position lines, has been a objection to celestial position fixing method. But using a computer , the severe objection will be practically overruled. The author had already studied on computerization of the sight reduction partially. This paper is to confirm reliability of coordinate of the moon and the navigational planet calculated by computer programming and to suggest a method of calculating ship's position fixed by two position lines.

Computerization of ultrasonic scanner is considered to achieve more quantitative and reliable ultrasonic testing. Testech LS-24 ultrasonic scanner is modified, and step motors in this modified ultrasonic scanner are driven by multiprogrammer controlled by computer. Two step motors can be controlled independently and simultaniously. The performance of computerized ultrasonic scanner is examined entloying modified C scan for a flat bottom hole ultrasonic reference block.

According to the computerization of railway signalling system, necessity of communication protocol for interface between these equipments is increasing. Therefore the research on communication protocol structure that is required according to computerization trend of these signalling goes. In our research the existed protocol currently used was analyzed, and the simulation modeling for performance analysis is deduced. Based on this simulation model the performance analysis and comparison is carried out, and also validation test is executed about new suggested protocol.
