In this paper, design of framework architecture of pervasive computing system providing seamless inter space interactions between private and public smart spaces is presented. The seamless inter space interaction issues are related to establishing user's service environment by allocating relevant resources in a new location where there are no prior settings for the user or where there are current users already being served in the new location. In the realm of pervasive computing, we can have different types of smart spaces, offering proactive and intelligent services, which are islands of smart spaces independent from each other. As users move about, they will have to roam from private smart space to public smart space and vice versa. When they enter a new island of smart space, they will have to setup their devices and service manually to get the same or different services they had at the previous location. Users might be living in a non-pervasive computing environment because this manual operation is inappropriate to its generic features of proactive and intelligent services of pervasive computing. The framework architecture will provide seamless inter space interactions initiated by changes in users' location to acquire negotiations of resources for new and current residents regarding service provision with limited available networked devices.

According to the policy for "e-Korea construction" of Korean government, Investment of information system during the past decade are dramatically increasing. More than a half of this investment is cost of hardware infrastructure. So, accurate hardware sizing are essential for higher efficiency of investment. Accurate hardware sizing benefits are generally viewed in terms of the avoidance of excess equipment and lost opportunity costs by not being able to support business needs. Unfortunately, however, little research effort to make the hardware sizing methodology are doing. We propose a sizing method for information system in public sector. This method is determinate empirical study that are gathering and analyzing cases, making method and reviewing expert. Finally we are proposed calculating method for hardware components that is CPU, memory, internal and external disk according to the application system type which is OLTP, Web, WAS. Our study certainly will act as a catalyst for higher investment-efficiency of the future information programs in public sector.

Hardware sizing is determinated by an increasing rate of operated business and characteristic of adapted technology which are imported systems. Because it is very difficult for intuitive decision of hardware sizing's appropriateness. But in sprite of difficulty, for maximizing the utilization of information resource and the effect of information investment in public sector are need to correctness hardware sizing. In this paper, we proposed hardware sizing method for OLTP server that is make up It's faults of proper proposal method. Our study certainly will act as a catalyst for higher investment-efficiency of future information systems in public sector.

In modern times, it has been a most imporant problem for the community to make nation's information resources a\-ailable to all the people ~vithf ree and even access. In Nelson Associate's National platz for library service appeared in 1948, 50 million Americans were served by public libraries with inadequate service and 35 million have had no library service. Library Services Act signed bq- President Eisenhower in 1956 was a result of continuous efforts of AL.1 for 20 years. It aimed to extend public library service to rural population less than ten thousands. LSA was succeeded by LSCA in 1964 and continued with several amendments so far. 620 million dollars of Federal funds were put into local library administrati1.e agencies during 1957-1974 for the extension of library service and construction of library buildings. Federal funds also encouraged local library administrative agencies to ha\-e more interest in library and information service and carry out their own library programs. However, there are many current problems in Amierican pubic libraries still now, that is, uneven growth of public libraries, uneven distribution of information resources, inadequate library service to a large part of population, insufficient supply of library funds, lack of nationwide library network beyond local admini-strative jurisdictions and so on. National Advisory Commission on Libraries, Committee on Libraries, National Conference of Library and Inforination Science are results of government efforts to meet those problems and carry out effecti1.e nation's library policies. In other part, Congress authorized to open the White House Conference on Library and Information Science before 1978 to make a reco:nn:endation fostering the library use. It is expected that the elected President Carter will put more efforts in developing library and information services, for LSA and LSCA were mainly pushed ahead by Democratic Party. In conclusion I could find some factors through these analysis that would be of some help to develop nation's library and information services, especially in developing countries.

Enterprise Architecture has become a key tool for transforming business process, data, IT and application resources. The "Efficient Adaptation and Management of Information System Act" was established to support the planning and development of the information system in order for the public sector to adopt Information Technology Architecture (EA) into its organization through the act. Until now, the study of EA has been mainly focused on concepts, methodologies and success factors for the implementation of EA. User involvement, which is one of the critical factors in adopting information systems, has been rarely studied in the field of EA research. The purpose of this study is to identify the effects of user characteristics on user involvement in EA implementation. After discussing intrinsic motivators and situational motivators as predictors of user involvement, a research model were developed and tested using survey data. The results showed that among intrinsic motivators, perceived competence had a strong positive effect on user involvement. Some implications were discussed for implementing and utilizing EA for public agencies.

In this paper, we address security issues in 5G non-public networks for industrial applications. In contrast to public networks that offer mobile network services to the general public, 5G non-public networks provide 5G network services to a clearly defined user organization or groups of organizations, and they are deployed on the organization's defined premises, such as a campus or a factory. The main goal of this paper is to derive security threats and potential security requirements in the case that 5G non-public networks are built for discrete and process industries according to the four deployment models of 5G-ACIA (5G Alliance for Connected Industries and Automation). In order to clarify the scope of this paper, we express the security toolbox to be applied to 5G non-public networks in the form of the defense in depth concept. Security issues related to general 5G mobile communication services are not within the scope of this paper. We then derive the security issues to consider when applying the 5G-ACIA deployment models to the industrial domain. The security issues are divided into three categories, and they are described in the order of overview, security threats, and potential security requirements.

A transportation problem in Korea is a serious issue that has to be solved urgently in the motor era of 15 million vehicles. Recently ITS has been introduced to improve efficiency of the current roads because an excessive budget and a long term construction are needed to build new roads. Therefore the government enacted the law as of ITS and the in architecture. However, these ITS information services were oriented to mainly vehicles and drivers, not public entities such as bus driver, passengers and so on. Nowadays lots of local autonomous city introduced a public transportation information system (PTIS), and providing useful information for the public. For this PTIS, important design issues are to be focused on detecting and tracking technology of moving bus, and a wireless communication link to transmit the location information. This paper presents design models using several wireless communication methods, and an implementation case using a Wireless packet Data communication Network (WDN) to transmit bus location information at Seoul, Korea.

Recently, public service for the improvement of quality of life and life support such as safety, aging, disaster, welfare, housing, economy, urban environment, traffic etc are actively developed based on open public data, and the spread of the network and the necessity of everyday life, smartphones are playing a role in providing public services. Currently, the development of science is changing the life expectancy of human beings and changing into social structure in which aged people become bigger due to various social conditions and low fertility and aging problems. However, the elderly who do not have easy access to information are very uncomfortable in dealing with mobile devices with very low accessibility and utilization of public services provided by mobile phones. Therefore, this study recategorizes the condition of the elderly presented in the previous study and identifies the problem through case analysis provided for the elderly. Also, we summarize the hierarchy of the core items of the existing interface design and derive it as an improvement index of the public service design for the improvement of the information accessibility of the elderly, and propose a design method to improve the utilization of the public service provided through the mobile device.
