The required standards for environmental tests for communication and electronic equipment used currently in the army are not standards into which the Korean climate and use environment are taken into consideration. But the environmental testing standards of the U.S. army at the time of its establishment(MIL-STD-810) “A” version has been used without taking into consideration the Korean domestic situation and conditions by simply translating the US standards. Adherence to these standards may limit the ability to supply materials in case of emergency since the increase in the manufacturing costs according to excessively strict standards induces an increase in the acquisition cost of military equipment, unnecessarily high maintenance and repair expenses are consumed, and stocks of parts for the military use have to be retained at all times.

The information material in the library or in the information service center is at once its own property and the national resources, so that every citizen in the country has the right to the equal use of it for the development of the country. Library co-operation enables every citizen to use easily and equally the materials in the library. In the informational society of today, owing to the information explosion, the increase in the various user's demand of the information, and the rise of the cost of information material, even the richest and highly advanced country cannot be self-sufficient. Under these circumstances, the international co-operation among libraries seems to be the best way to solve the difficulties of selfsufficiency. Therefore, this paper aims to study the background of IFLA founded in 1927 in order to promote the international library co-operation and its development up to 1970's since its establishment, and, by introducing IFLA's programs of UBC, ISBD, and UAP, to consider the significance of IFLA's contribution to the development of library and librarianship.

A variety of enterprises have Implemented ERP system on the promises of feasible strategic benefits. The objectives of this study are (1) to classily and analyze the motives and critical success factors o the enterprises'ERP system adoptions, and (2) to measure their impacts on the business performance. The data for this research were collected from 43 cases in Korea that have operated ERP system for more than 6 months after the implementation. This study results reveals that the Information strategic planning and business strategy establishment prior to ERP adoption and the demands of field people activate as critical triggers In the larger firms Among the six critical success factors, training was statistically significant for all of four performance measures control, cost reduction, quality and service, and work efficiency. And other findings are furnished. Also the larger company group In the sales volume has shown the higher performance except work efficiency.

This paper focused on problems of design, construction, and maintenance caused by construction implementation processes. They were analyzed through case study of structure safety diagnosis projects. From the case study, it is expected that the introduction of Construction Management from the first stage of procurement will improve construction cost increase or burden on small design company. It strengthens coherent management from design and source contractor selection to build review of responsibility. The coherency will prevent changes in designing or infirm unreliable construction. It is desirable that expert opinions are considered when structure changes and establishment occur and that, if necessary, actions such as source selection, periodic audits, and diagnosis arc checked and fed back to maintenance.

After the introduction of the World Trade Organization, large scale container ships are being used as a means of transportation for international trade. Therefore, improving the loading and unloading capability of container quays is the most economic way, considering the cost needed for the establishment or expansion of container quays. In this paper, a new container cargo handing system that is equipped with a high performance container crane is suggested. A structural analysis on the container crane is also conducted to decide the form and size of structural member scantlings, using NASTRAN, which is a general structure analysis program.

Recently the demand of the driverless rolling stock is increasing with advancement of the stable communication technique and control technique. The automatic train operating system has advantages which takes low operating cost and is able to dispose elastically in demand. Beside it provides high safety and effectiveness because it will be able to control power, signal and communication system from Operation Control Center and the safety and effectiveness are high. The establishment of PSD, Platform Screen Door, is advanced in the goal which is passenger safety, fire protection, noise and dust reduction etc. When but, two advanced systems also have risks of operation delay and accident when two systems are not controlled smoothly. Thus, I'll introduce control method between onboard controller, door control unit in rolling stock and PSD controller to help system design.

Government is supporting development of home networking. But, this new system is much expensive to introduce in the home. And limit for establishment is so many in the home. Therefore, in this paper, Present direction of home automation system that can have high effciency into low expense, induction of automation system is easied in the home. Also, install can be easy and do remote control in PC, HP, PDA because use RF, DB.

Mega-Y project is very important for a company to gain a competitive advantage in markets or to achieve drastic change in the internal processes. It stems from the company strategy and annual management goals or key performance measures, and is proceeded by the cross-functional team. This paper presents the success factors and implementation process of the Mega-Y projects. The implementation process is presented in 5 steps, including project selection, cross-functional team building, establishment of the master plan, development and execution of sub-projects, and project completion. A case study on the cost reduction project of aircraft development is presented to help for the practitioners to deploy the implementation process introduced in this paper.

Reconfiguration, expansion, or new establishment of FMS requires the availability of a shop floor control (SFC) system relevant to the FMS since it is closely related with the hardware component of FMS. Due to the expensive cost of its development, significant research efforts have been made to develop an SFC system that is reusable. This paper presents Abstract Machine Tool (AMT) approach applied to develop an SFC sytem that is reusable without additional programming. The AMT model enables us to design the SFC system independently of the hardware-dependent attributes of euqipment; an AMT models a workstation by abstraction and presents an equipment-independent interface to machining cell controller. Specifically, we describe how we formalize the interfaces among equipment in order to build an AMT and how we design the machining cell control software based on AMT models. We also present MACHINIST the machining cell control system for IAE-FMS plant as an implementation example.

The importance and interests for saving of energy and cost in industry has grown up. Therefore, process optimization to reduce the process and energy become one of the most important things. The non-heat treated steel, post-heat-treated is no necessary, has attractive points as structural materials. However, establishment of mechanical properties is necessary to apply non-heat-treated steel to structural parts. In this study, for non-heat-treated steel and pre-heat-treated steel, we have investigated microstructure, hardness, the tensile strength, compressive strength. And the FE analysis technology to predict the hardness value of forged part is developed on micro-alloyed steel forged part.
