We can use document issuance services provided by a school, bank, hospital, company, etc. either by visiting those facilities or by simply visiting their Web sites. Services available through the Internet allow us to use the same services as we do by actually going to those facilities at home or office any time. As much as it saves us time and money, there also arises a problem of information being forged on the Internet or on a printed document. There has to be security functions to deal with the problem. This paper intends to think of the possible security threats and draw out the necessary security functions that an on-line document issuance system should have based on the CC v3.1, so that anyone can use it as reference when they evaluate or introduce the system.

This paper aims at developing communication module and application prcgram for client management module and developing database management module and managing wireless communication facilities for server systems. To construct these aims, we have adapted DES algorithm and researched on encrypting and decrypting module development applicable to SMS Security System and optimize module size and processing speed.

This paper is the introduction of our work on distributed load scheduling in single-level tree network. In this paper, we derive a new calculation model in single-level tree network and show a closed-form formulation of the time for computation system. There are so many examples of the application of this technology such as distributed database, biology computation on genus, grid computing, numerical computing, video and audio signal processing, etc.

This paper presents the classification scheme of the signal facilities on the railroad considering the construction costs and maintenance costs in a low population area. The construction costs of the new signal facility system can be compare with the costs of the present signal facilities as the classification scheme. The signal facilities on the railroad were classified as the railroad security regulations and then the scheme is considered through the LCC analysis. In order to test this research, the costs of signal facilities obtained from ones on TAEBACK railroad line. The costs categorized the construction costs, the labor cost and the maintenance costs can be effectively applied to the LCC analysis. The scheme is very useful to make a decision whether the new signal facilities on railroad in low population area is build or not in terms of the costs.

A questionary survey was conducted to investigate citizen's attitude to treatment facilities of municipal solid waste in Miryang during 8. June of 1998 and 22 June of 1988. Collection effiencies was 86.7%, as 260 individuals of the 300 individuals. The survey showed that 43.0% of answers recognized seriousness of problem of the waste treatment and 33.1% of respondents concerned about recycle of organic waste. 40.8% of total answers said that they most hated landfill site among waste treatment facilities, and most citizens wanted as much distant as possible from waste treatment facilities. It was investigated that the greater part of respondents wanted the greatest compensation. About 58% of respondents was opposed to complete waste treatment facilities. 36.2$ among answers wanted establishment of waste treatment facilities in an industrial complex or an industrial area. The majority of respondents was willing to increase recycle rate and recognized seriousness of landfill site security. The majority of citizens do not trust environmental administration of Miryang City and they think that democracy and open of administration need for overcome MINBY.
