This paper is focused on the desirable improvement schemes of the local network of information and telecommunication network. In this study, we examined whether polices of information and telecommunication of government have been carried out a desirable programme to meet the public interest, found out several problems in the these policies. Such problems as follows : (1) a system of local information & telecommunication is developing by a Model of Top-Down. In the present management system, an interest of the public of local society about the local telecommunication network is a much lower level, (2) there is no general controlling roll of the local information & telecommunication, (3) there is no service controlling system of local telecommuni-cation, and (4) there is no organic coordinating system of inter-departments in the central government level. In order to resolve these problems, this study suggests a few desirable sxhemes for the local telecommunication : (1) an establishment of middle-long range planning for the integrated future network of info-telecommunication, (2) an organizing of telecommunication network being suitable for the local characteristics toward B-ISDN.

The purpose of this study is to make an empirical analysis on the factors affecting the intention for the continuous use of the BSC system, which has been recently spread in the public sector. Because the object of acceptance is the performance management system based on BSC (Balanced Scorecard) implemented in the form of information systems, this study proposes a research model by applying TAM (Technology Acceptance Model). Independent variables are factors affecting the acceptance of BSC system such as training, communication, IS support, CEO support and personal innovativeness, and we examine their effects on the dependent variable, namely, intention on continuous use via mediating variables: perceived usefulness and perceived ease of use. A questionnaire survey was conducted with public institutions(firms) that had introduced and were operating the BSC system; 264 valid questionnaires are adopted. Collected data are analyzed using SPSS 16.0 and AMOS 7.0. Results of reliability test show that all analyzed data are reliable. In validity test, one item regarding communication was excluded; 9 latent variables and 34 observed variables are used in the final analysis. Based on the results of the hypothesis test through path analysis using a structural equation model, 10 out of 16 hypotheses are accepted. Factors affecting perceived usefulness are training and IS(Information System) support. The analysis results indicate that perceived ease of use is mainly affected by IS support, CEO support, and personal innovativeness among the factors related to the acceptance of the BSC system. This suggests that, contrary to the expectation that the BSC system may be used without difficulty, the management's active support is required in order to attain expected improvement in productivity and work efficiency. This was also pointed out in case studies on the construction of the BSC system in public sectors. On the other hand, perceived ease of use is found to affect perceived usefulness. This supports the results of previous researches on TAM. Perceived ease of use and perceived usefulness are found to affect the attitude towards the use of the system. The intention on continuous use is affected more by perceived usefulness than by the attitude towards the use of system. This result supports the results of previous researches on TAM, showing that the BSC system is utilized substantially in worksites. This study is considered meaningful in that it was actually performed on users at public institutions(firms) that had introduced the BSC system and that it empirically tested hypotheses on the acceptance of the BSC system by applying TAM to the research model.

In recent years, Korean public libraries, placed under changing circumstances, require that some new and positive financial policies be formulated for the improvement of their services. T he purpose of this study is to propose a scheme to ensure the revenues of Korean public libraries. The main contents of this study are as follows : (1) Public finance theory is applied to the question of why the public library is publicly supported. The public library does not contribute to stabilization, but it does playa role in each of the other public sector functions : allocation of resources and redistribution of income. In public finance terms there is justification for at least partial subsidy of public library services, which have the attributes of public goods, merit goods and externalities. (2) Public libraries in Korea find themselves suffering from limited budgets. They are neglected in national and local budgets. The lack of adequate funding for library collections prevents libraries from rendering efficient services. (3) In order to put the finances of the Korean public library system on a firm basis, the following proposals are made: 1) It is proposed that the parallel administration under which public libraries are organized be unified to be directly under the local governments. 2) It is proposed that the legislative and administrative system for public library finance be strengthened. (1) Library expenses should be itemized independently in the calculation of general grants-in-aid to local governments. (2) A fixed portion of the total municipal revenue should be appropriated for public library services. It can be executed by making provisions expressly in the annual guidelines for budgeting, municipal ordinances, or in the Library Promotion Law. The rate of allocation should be specified as a part of the national public library development plan. (3) Library tax as a local tax can be imposed. An indirect tax is preferable in order to avoid public misunderstanding and antagonism. 3) The augmentation of the specific grants-in-aid for the public library is proposed. The Library Promotion Law and the Law on Budget and Administration of Grants should be amended to oblige the central government to give financial assistance to local public libraries. 4) It is proposed that strategies to encourage private endowments be worked out. Revision of the Law on Tax Reduction and Exemption and the activation of an advisory library committee at each public library are recommended. 5) Funding and utilization of the envisioned Library Promotion Foundation is proposed. Government contributions, contributions from the Culture and Arts Foundation, and donations from individuals, corporations, and enterprises can be considered as the financial resources of the Foundation. 6) It is proposed that the structure of the Korean Library Association be consolidated to exercise greater influence over the formation of national policy on the public library system. 7) It is proposed as an ultimate guarantee of the health of the public libraries that the citizenry be educated to strongly support library services in responce to the active services provided by the public libraries.

Bimodal Tram is the newly developed vehicle for both the tracked way and the public road. Its operation system has some characteristics including BIS(bus information system)/BMS(bus management system) based on ITS(intelligent Transportation system) which is used presently in public transportation operation system. One of them is more accurate vehicle fleet control based on both magnetic maker position reference system and GPS(global positioning system) and the other is automatic vehicle control for emergency situations by the Bimodal Tram operation system which will be performed by the unified control and operation center. This paper has investigated the requirements and functional definitions necessary to construct the unified control and operation center for Bimodal Tram operation system which will be more efficient and secure public transportation system than the conventional ones.

The paper describes the implementation of the video conferencing system using public key infrastructure which is used for user authentication and media stream encryption. Using public key infrastructure, we are able to reinforce the authentication for conference participant and block several malicious hacking while protecting conference control information. The paper shows the implementation of the transportation layer secure protocol in conformity with Korea public key authentication algorithm standard and symmetric key encryption algorithm (RC2, SEED, DES and 3DES) for media stream encryption. The feature of the paper is transportation layer secure protocol that is implemented for protection of information on a user authentication and video conference and the media streaming encryption algorithm also can be envisioned with another block encryption algorithm. The key for media streaming encryption may be safely distributed by the transportation layer secure protocol.
