In this study, the experiments were carried out for the purpose of establishment of aluminium cementation to steel surface by diffusible heat treatment after making the coated film onto the substrate by arc spray method. Also, the microstructure and mechanical properties of the cementation layer produced by this study were inspected for various heat treatment and spraying conditions. Main results obtained are as follow ; 1. The coating film characteristics which have excellent errosion-resistance, high temperature oxidation-resistance are obtained by aluminium penetration heat treatment after making the sprayed aluminum coating film onto the steel substrate. 2. Aluminium diffusion penetration takes place at higher temperature than 660.deg.C, and the more heat treatment time and the higher heat treatment temperature adopted, the deeper diffusion layer obtained. 3. Insert gas arc spraying using argon gas as the carrier gas higher improvement of mechanical property than that of compressed air environment. 4. The coating film characteristics appeared to be improvement of adhesive property, porosity plugging effect by heat treatment in air environment.

This paper is focused on the introduction of the types of models and explanation of the fundamental concepts and theory for development and use of the corporate planning and modeling system. Nowadays, a great deal of companies have been or experimenting with some form of a corporate planning and modeling system to support managerial and strategic decision making. From previous studies it was noted that most applications have tended to be financially based. This trend will probably continue. However, with the software and hardware currently available it is likely that companies will move more toward integrated models that link marketing, production, as will as financial areas. More emphasis will undoubtedly be placed on the use of econometric modeling, since this subelement of the overall planning and modeling process is closely tied to the market place and the economy. At any rate, wherever the development of corporate planning and modeling system is directed, clear understanding for the fundamental concepts and elements of the system is settled in advance in order to develope and use it.

Thanks to China's economic development, the food service industry and franchise industry have combined to serve a huge market, and alterations continue to take place, such as the changing tastes of Chinese people and the changing food culture. Global franchise companies centered in the US are rapidly making inroads into the market, and Chinese local companies are also making efforts to expand their influence. In particular, in this situation where trends are gradually changing due to the COVID-19 pandemic, we look at the trends of franchise headquarters, franchisees, employment, and operating profits for the past 10 years using information published by the National Statistical Office of China. As we examine the information, possibilities push through. In addition, we will look at the cases of domestic companies that have entered China, the conditions and plans for their activities there, and what companies planning to enter China in the future need to prepare for.

An autonomous mobile robot has been developed which can follow a travel map drawn on a monitor screen using a software. The robot works as an exhbition guide making announcement regrading the events to take place or introducing the products on display. This mobile robot computes the world position and heading direction through camera image, ultrasonic and infrared sensors in real time using specially designed algorithm. This mobile robot will be exhibited at '93 Tae-Jeon EXPO for an exhibition guide, and will be used in a plant or a hospital for materials handling purposes.

The purpose of this study is to determine the direction of development of residential land in downtown of Taegu. The main findings of this study are follows. The residential land in downtown is narrow in size, has bad accessibility to road and has bad land shape. So if you develop the residential land not separately but related to near place, it will be more profitable. Especially, we can use Hedonic Price Model as a was of making better in economic.

Imprecision of evaluation or lack of prior information about preference can be an obstacle for decision maker in representing his strict preference. Therefore, fuzziness of preference can take place, and in addition, intransitivity or incomparability of preference becomes the critical difficulty in making complete preorder of alternatives. In order to get better solution and to improve practical usufulness, MCDM should be established as a pseudo-criterion model that include fuzzy preference. In this paper, we suggest a pseudo-criterion model that can make complete preorder of alternatives by metric distance measure.

The purpose of this article is to analyse the policy-making process concerning the selection of providers for IMT-2000, the global roaming communication services in Korea by adopting the new institutional approach. It is supposed to contribute to understanding the characteristic of the policy process in the field of information and communication. We can see the durability of institution through the process that the government lost its policy credibility by using the intervention instrument rather than letting go in the market place.

Persuasive emotion advertising has great effect on attention and motivation. The using of negative emotions has been an interest in consumer psychology and advertising. This is because emotions place impact on consumers, attention and decision making. Emotions are also believed to cretin evoke brand name from memory. This paper presents the evidence for the impact of negative emotions by comparing then greater with positive emotions advertising.
