The roll Pass design is one of the most important processes to design the whole equipment of the rods and bars rolling system. In this study, the roll pass design program named TollRo(Rolling Factory Organizer) was developed. conventional methods to design roll pass were analyzed and a new algorithm to design the dimension of the intermediate groove was introduced. Object oriented programming technology was implemented in this design program. It comprises GUI(Graphic User Interface), function of automatic pass design, function of modifying pass schedule and database of material properties. The developed program can be used to design roll pass with consistency for the rods and bars rolling system. The man-hours for the whole design can be drastically reduced. The design parameters of rolling system can be extracted quickly by this program.

In this paper, we developed a Hospital Information System in which the business process is formalized and a wire/wireless integrated solution is used. This system consists of the administration office program, the medical office program, the ward management program and the rounds management program. The administration office program can enroll and accept patients, issue and reissue the RFID card. The medical office program inputs a medical examination and treatment, outputs a diagnosis, requests a hospitalization, retrieves the record of a medical examination and treatment, assigns the corresponding examination room to the accepted patients, and updates the number of an waiting patient and a patient number according to the examination room on real time. The ward management program handles hospitalizations and leaving hospital, a nurse's note, and an isolation ward monitoring. The rounds management program handles a medical examination and treatment, and a leaving hospital using PDA. This developed system can be built at low cost and increase the quality of the medical services highly by making it automated the medical administration automation. Also the small number of the medical staffs can manage the inpatients efficiently by using the monitoring functions.

The basic concept of an improved business and productivity for Small and Medium Sized Enterprizes, which makes use of an information portal, is to assure competitive power, increase the production quantity through the interchange of a company and the outside environment, and to build cooperation. To reduce the charge of the equipment, as well as to introduce and information program, it should build an information environment from inside the company by suing the information portal ASP(Application Service Provider). This portal is already built by the basic information infrastructure through the Internet.

Automotive transmission is the principle component of vehicle driving system, which transmits the adjusted engine power. The automation of transmission arises from the annoyance of transmission operation such as the frequent stop/start of vehicle and the shifting transients. The study on the optimal shifting condition for the automation of transmission needs the investigation of shifting transients. However, the dynamic modeling theory during transient period is not well-established. In this study, the techniques of dynamic modeling for the power transmission system with Merrite-Wilson gear train are presented. To predict the shifting transients, a driving simulation program is developed, and the results of the analysis are cross-checked in the field test.

도서관목록의 자동화에 의해 많은 도서관은 온라인 열람목록의 환경으로 변환되었다. 따라서, 현재까지 국제적으로 표준화된 편목규칙으로 인정받아왔던 AACR2와 이를 자동화프로그램으로 변환시키는 MARC에 있어서 부분적으로 불합리한 점이 나타나게 되었다. 본 연구에서는 AACR2와 MARC에 대한 비판과, 갱신을 주장한 문헌을 살펴보고, 온라인환경에 따른 편목법의 실제적이며 구체적인 개선내용을 특히 AACR2R을 중심으로 제시하였다.

Recently, IEC61850 supports the standardized communication technique in both station bus and process bus, and presents the substation automation model. In this paper, we propose the required techniques to develop the Merging Unit (MU), which is one of the important data acquisition equipment in substation automation, under IEC61850 communication protocol. Especially, we also propose the precision time synchronization technique using GPS(Global Positioning System) for the MU. IEC61850-9-2 SV (Sampled Value) service is applied to the MU which is designed using microprocessor. In order to evaluate the performance of the proposed MU, the playback program, which can reconstruct the transmitted sampled value data on the basis of time information, is developed and the performance of the IEC61850 SV service for MU is verified experimentally.

The purpose of this study is to analyze the factors influencing on the organizational changes of the university libraries. Results of the analysis, that is, factors that cause the library organization to change, are as follows 1. Changes in library size physical facilities, growth and diversity of library collections, change in personnel organization, role enrichment and faculty status for librarians, management pattern of library director, change in financial su n.0, pport. 2. Change in program : change in goals and objectives, expansion of service programs, enhancement of library functions. 3. Library automation : introduction and development of many library automation projects. 4. Introduction of information technology : development and distribution of computer and related software, telecommunication, and new media. 5. Changes in user needs : many-sided demands for collections, spaces, and services. 6. Many other environmental factors related to library organization.

In order to completely automatize the moving load analysis for the three-dimensional frame model of the girder bridge, the efficient software technique is presented, which makes use of the signal among processes. If this software technique is used in automation, the separate algorithm is not needed for the transverse loading analysis, and the complete automatic moving load analysis algorithm can be easily developed. The program, which has the complete automatic moving load analysis function, has been developed with using this software technique, and has been verified by comparing the results with the one in the famous design book.

Seven axis modular type pneumatic manipulator is composed of electro-pneumatic automation system which contributes to factory automation by performing loading & unloading process successively which is simple routine work of dealing item of machine tool, catapult, assembly machine, welding machine and so on. In this study, we obtained soft and quick movement in a large space and good reliability motion of various function by combining several actuators which perform rotation movement as well as linear movement at the same time. Gripper which apply to rotary sensor transmitted a structure to demanded position. This development item of 5kgf load prevent stick-slip phenomena of stroke end by designing high cushion internal. We develope flexible manipulator which conforms to demand of user by applying multiple sequence program.

This paper presents design automation system using API and parametric modeling of solid modeler, which is applied on axial fans for cooling towers. The design data including chord length and twist angle according to the fan length are given by design program, and API functions are applied to automate the modeling and assembly process of fan blade. The boss to connect fan and motor is designed with parametric design function provided by UG so as to be flexibly changed by the value of design parameters. The process of generating 2-D drafting for parts and an assembly is also automated. With developed system, the modeling time is reduced to 5 minutes even with unskilled operators.
