The objective of this study is to suggest modified Covariance Structure Analysis that combine with existing Multivariate Statistical Method which is used Casual Analysis Method in Management Information. For this purpose, we'll consider special feature and limitation about Correlation Analysis, Regression Analysis, Path Analysis and connect Covariance Structure Analysis with Statistical Factor Analysis so that theoretical casual model compare with variables structure in collecting data. A example is also presented to show the practical applicability of this approach.

This study is on the differences of the functions of definitions between in proof geometry and in intuitional geometry. There are the functions of definitions in intuitional geometry which may connect to those in proof geometry. We assert that when we teach them, we should be careful, for the teaching of the functions of definitions in proof.

The importance of training for NC, CNC and Machining Center has been greatly increased. This paper presents implementation of a DNC(Direct Numerical Control) operating software for educational system. This system is able to connect 8-32 CNCs to Control PC with RS232 multi-port serial card. Therefore, it allows much efficiency in training even after costs are considered. The KISCO DNC S/W for above system includes various communication functions, communication parameters setting, program editor and user-friendly environment. This software was developed with C and Windows programming. It was proved in function and stability by iterative field tests.

본 연구에서는 산악지의 정상 근방의 등고선 상에 존재하는 끊김을 연결하기 위한 극좌표계 선형 보간방법을 제안한다. 그래픽 영상에 대해 기존의 재구성 알고리즘들과 성능을 비교한 결과, 제안된 극좌표계선형 보간이 인접 등고선의 외형과 유사한 선분을 생성함에 의해 자연스러운 등고선을 재구성하는 것으로 나타났다.

This paper describes development of an implantable power switching system for biotelemetry system. This system is designed and manufactured to achieve as small size and low power dissipation as possible, using pulse powered circult and CMOS technology. The function of the power switching system is to connect the implantable battery to implanted sensors and, electronics systems by receiving intermittent command signals from external circuits. The power dissipation of this system was about $15{\mu}W$ for a stand-by operation.

Recently we cannot almost pass a day without watching a word internet on TV or in the magazings; but the history of internet is considerably old and it has passed more than 30 years. The internet (internetworking), as we know from the words "international"or "interstate", meant originally to connect computer network, but at the present time generally it means one particular network connecting the world. We are being surrounded by the internet so rapidly that I would like to describe its historical background, present status, further it′s subjects, future prospect of th internet.

Due to the improvement of PC Performance and Windows-based OS, PC-based control system is gradually taking over industrial control in the industry site. In this paper, we suggest the method to configure PC-based fault diagnosis system of I/O cards and the method to generate test signals to find out the short conditions of adjacent channels of cables which connect I/O cards with terminal blocks.

Variable-gauge systems can be used for the fast and safe transportation in the railways with different gauges instead of transshipment or bogie-changing. The system will be necessary to connect the trans-Korean railway with the transcontinental railway effectively. In this paper, searches of patent information about variable-gauge system are conducted and the patent maps are analyzed to seize the overall image and trend of the technology field. The results can be a reference for determining the development direction of the variable-gauge system suitable in the north-east asian railway networks.

Recently. our construction industry is using 4D-CAD system but the public Database (DB) for the 4D-CAD system is insufficiently built. It is difficult to connect 4D-CAD system information such as schedule, drawings. Therefore this study suggest a methodology to link the 4D-CAD system information with work breakdown structure(WBS) and the methodology suggested in this study was applied to a 4D-CAD system
