The liberalization of Korean distribution market will undoubtedly lead to some erosion of market share of indigenous distributors in PC GMS(General Merchandising Store) & all the industries, but to our surprising, the benefits of rationalization of distribution, high qualities & low prices, strengthened competitiveness of indigenous retailers far outweigh the costs. The aim of this paper is to present some basic executive ideas for achieving a more global competitiveness in the 21st century. That is, successful market responsiveness in our distributors & firms will first of all require Dynamic Supply Chain Management at the base of information infrastructure to obtain the best competitive power. Secondly, in practical perspectives, distributors & firms needs to learn precise analysis on the basis of customer needs & wants as well as flexible thinking & proactive attitudes with respect to an freezing markets. In conclusions, win-win strategy in the competition for existence has to retain continuous & close relationship between cooperation and coordination.

The dispersed generation is recently increased introduction for the energy supply rationalization and effective management of power system. But the dispersed generation causes to the various trouble that isn't occurred in the past, for example, the two way systems have an effect on the mistake action of protection equipment and the power quality. In this paper, we research the influence on the harmonic when the dispersed generation is interconnected with distribution system. To achievement, we construct the interconnecting dispersed generation and distribution system which is applied to the permission of harmonic emission. After that, we simulate about the harmonic of distribution system interconnection dispersed generation by the PSCAD/EMTDC analyzing transient state of the power system.

Recently, The business environment is very rapidly changed and complicated. Therefore, the companies are confront with the biggest difficulty. To overcome this difficulty, the management should be able to accomplish the human resources management and the efficient business management. Korea railroad industry has a close association with national life as it carries out public works based on its public nature as well as purses the corporate spirit. For that reason, Korea railroad industry has a great spin-off on national economy and exerts a tremendous impact on the improvement of productivity around the industries and the international competitiveness at aspect of efficiency resulting from business rationalization. Railroad system can be described as organic. Railroad Employs take a great role in this system. According the psychology and the Organization Behavior, the decision maker's personality and employee' work satisfaction have influence on performance. The purpose of this study is to examine the Railroad Employs' Personality and Work satisfaction which influence on the efficient business management.

Recently, owing to efficiency of the concrete work and the rationalization of construction structures, concrete is required to be super high strength. Furthermore, it is take a growing interest in execution and manufacture for super high strength concrete. This study is to investigate and analyze the influenced of flyash affecting on workability and engineering properties of super high strength concrete. In this experiment, the 28day's compressive strength of concrete using 15mm size of aggregate and flyash is over 800㎏/㎠ in the 20°/wt of water∼cement ratio. And the concrete using flyash have higher tensile strength than plain concrete.

Due to the high feed rate,high speed machining (HSM) provide a great potential of rationalization for the machining Dies and Moulds. But determination of cutting condition is very difficult, because cutting mechanism of high speed machining is very complicated,especially using ball end-mill. This paoer gives a report on selection of the optimal cutting condition to improve the machining efficiency, And optimal machining condition is determined through the cutting force, FFT analysis of cutting force and surface roughness according to the cutting condition. Based on this experiment result,wear process and machining characteristics are evaluated.

Contemporary architecture tends to deconstruct modern architecture based on rationalization just like reductionism and functionalism and secedes from it. It means change from mechanical to organic and ecological view of the world. According to these changes, consideration of a compositive relationship presented variety and complexity in architecture. Thus, the modern speculation based on rationalism cannot provide an alternative interpretation about complicated architectural phenomena. At this point in time, the purpose of this study is to investigate the possibilities of the fractal as an alternative tool of analysis and design in contemporary architecture. In this study, two major aspects are discussed. First, the fractal concepts just like 'fractal dimension', 'box-counting dimension' and 'fractal rhythm' can be applied to analysis in architecture. Second, the fractal formative principles just like 'scaling', 'superimposition trace', 'distortion' and 'repetition' can be applied to design in architecture. Fractal geometry similar to nature's patterned order can provide endless possibilities for analysis and design in architecture. Therefore further study of fractal geometry should be conducted synthetically from now on.

There have been significant changes in the Korean railway environment in recent years. First, as the railway restructuring plan, Korea Rail Network Authority and KORAIL were established and commenced their works. Secondly, the opening of the high speed railway has provided a chance of reorganization in the whole operation system of the Korean railway network. These new changed environments require an alternative plan to examine the management system of deficit lines and their stations. This paper is intended to approach to clearly define the concept of deficit rail stations and lines in order to make a contribution to establish a comprehensive rationalization plan in the management environment of railroad. The study proposes some method to categorize their deficit stations and lines by three ways.

This paper grasped the labor productivity actual condition by the standard of per unit working hour and production about the main products of our country's industrial the main materials and could understand the average of our country's labor productivity as compared this with the labor productivity actual condition of Japan. As the point at issue of analitical result. 1. Low a matter of thinking about productivity. 2. Have a lot of difficult problem in an industrial part. 3. Have the point at issue on technical development and accumulation. 4. Have the point at issue on management. As a countermeasure about these. 1. must convert the way of use of industrial policy. 2. must make a housing development and special serialization of a small and medium enterprise. 3. must establish an organic technical development system. 4. must grope the policy of management rationalization.

Upland weed control in Korea has been in dilema with the radical problems prior to weed problems, as it were, poor farming conditions, low yielding, no farmers concern, lack of political cares, and low returns for farming, etc. In these respects, the study was intended to collect all concerns to upland farming conditions and to array all research informations contributed upon Korea upland weeding, and at last interpreted its problems in order of importance. Especially expecting the reasonable and common use herbicides upon the most uplands in Korea, the crop compatibility and weeding efficacy by the most herbicides upon each crops were investigated from the experiment results. Among other interpretations of research results, the most important and first of all acceptance was for the direction and methods of weed research to be rationalized. And that weeding programs in level of upland farmers should be cautionsely and gradually propagated was interpreted to be accepted. Also, for the reasonable development of upland weeding situation in near future, the integrated promotion of upland farming rationalization is suggested by schematic explanations.
