This study was carried out to figure out the relationship between EAmaturity, information management capacity, and information performance, and find the effect between these variables and the reciprocal causation. The study found that EAmaturity has a positive effect on information resource management and performance. In other words, the effect of input, calculation, management and utilization factors on information planning in EAmaturity showed that calculation, management and utilization factors have a significant effect on the information planning. While the effect of input, calculation, management and utilization factors on information introduction and management showed that only both calculation and utilization have a significant effect on the information management factor. It says that EAinput in EAmaturity does not play a big part in the planning stage, as well as not go through a series of process that is connected to the maturity stage by immediate field application. Consequently, EAmaturity varies from the level that EAcreates introduction and performance according to organization. This suggests that the maturity and performance can be also changed by the level that EAcreates information performance by accepting and using this capability within organization as well as the capability to introduce and fully perform the EAsystem presented in enterprise architecture framework of public sector.

In this paper, we introduce InfoDID, a robust user information management service based on DID that manages user information reliably. Since blockchain technology provides an environment in which data can be handled transparently on a decentralized basis, various services using blockchain are currently being developed As the importance of user's personal information has recently emerged, the DID technology is receiving attention. The technology allows a user to control his or her information through decentralized identifiers, and various information management services are being tried based on the technology. Using blockchain-based DID technology, InfoDID reliably controls personal information requested frequently, helping users to provide their information to other services more conveniently. In addition, to support service continuity, InfoDID uses BR2K technique that provides robust execution of blockchain application services, so that even partial service failures can be systematically recovered. To facilitate this operation, we present a replication status monitoring tool that can continuously check the replication states of blockchain application services running in association with the BR2K technique such as InfoDID.

The study aims to establish the concept of customerized research information services in academic libraries and to build librarians' consensus on the need for customerized research information services. The literature review enabled summarizations of the definition of research information service, customerization, and research trends. A categorization process resulted in a list of research information services of academic libraries. The Delphi method survey revealed the necessity of providing research information services and applying customerization to research information services based on the opinions of librarians. The librarians agreed on eight research information services using customerization services. This study has significance because it proposed new attempts to improve and develop research information services and explored ways to enhance the expertise and value of academic libraries by forming a consensus among librarians.

Recently, some applications require the multicast service that transmit messages to multiple destinations in computer communication network enviroment. Multicast service is to send messages to the group which consists of a number of processes. A multicast group is a collection of processes which are destinations of the transmitted messages and these processes may run on one or more hosts. Therefore, it is important to manage each member of process groups in order to provide efficient multicast services. In this paper, we design and implement group management system to support multicast services. Group Management System was designed with Process Group Management System(PGMS) and Host Group Management System(HGMS). We have implemented basic primitives of PGMS, HGMS. Also, membership tree management algorithm is designed and implemented. Membership tree provides the relation of the members of multicast groups and routing Informations.

This study aims to understand why public information systems in agricultural fields have shown lower performances than other industrialized fields and industries and how these problems would be fixed and overcame. To accomplish this research purpose, this study would overview the previous studies on developing agricultural information systems in public sectors and would find out meaningful and considerable factors. This study would accept the methodologies of literature review and systems thinking approaches to understand the relationships among the found factors and to suggest the conceptual research model. Agricultural information system should take care to reduce implement and maintenance costs to reduce the negative relationships between costs and expected service value and between expected service value to perceived service value. Also, it should be understood that impersonal response would reduce the eager to use the services, so the government sectors should consider positively to adopt the concept of CRM even though the government sectors traditionally have ignored its necessity. The failure of public information systems/services may be caused not only by lack of the contents but also by the failure of the persistent post management.

Personal information has been stolen continuously and it is also affected from development of the Internet. So the government requires that companies spend more effort for protecting customers' personal information. The OLAP server also should meet this requirement, but it is hard to satisfy for the authority management. The OLAP server must use personal information to extract required information from database. This thesis suggests a model of separating between general information and personal information, so this model can help to minimize the leakage of personal information. The model is implemented and tested as a prototype. This prototype can prove that the new model is better than the original one. This study presents that the authority management on the separation between personal information and general information helps protect the personal information of customers.

Unlike the past, university libraries are able to provide specialized and differentiated information services due to the advent of information technology and telecommunication. Such services are essential not only to the primary users, such as professors and students in the universities, but also to the external users including corporations, researchers, and the general public. Now, university libraries as a means of resource sharing with communities should develop the services to play a role as a research and information center and expand such services to outside users who need the information services. Accordingly financial support is a necessity to provide the services, thereby fee-based information services are one of the devices for solving the financial burden and controlling outside users. This paper tries to present a program for fee-based information services which are able to be implemented by university libraries. Also the papers deals with the present conditions of fee-based information services provided by university libraries briefly and the goals of the program; coverage of subjects and types of materials for the program; organizations and staff; types of fee-based information services; management methods of program.

Although more than 99% of all Korean companies are small and medium-sized enterprises (SMEs), which accounts for a large part of the national economy, they are having difficulties in securing information protection capabilities due to problems such as budget and manpower. On the other hand, as 97% of cyber incidents are concentrated in SMEs, it is urgent to strengthen the information protection management and response capabilities of SMEs. Although the government is promoting company-wide information security consulting for SMEs, the need for supplementing it's procedures and consulting items is being raised. Based on the results of information security consulting supported by the government in 2020, this study attempted to derive improvement plans by interviewing SME workers, information security consultants, and system operators. Through the research results, it is expected to create a basis for SMEs to autonomously check the information security management system and contribute to the reference of related policies.

Purpose - This paper aims to investigate the mediating effects of relationship fairness factors between franchisor's support services and performance(re-contract intention) in food service franchise. More specifically, fairness was measured into distributive, procedure, interaction, and information, franchisor's support service was divided into pre-start support services (initial support services) and post-start support services (continued support services), and performance (re-contract intent) was measured using 3 items such as re-contract, contract extension, and recommendation. Research design, data, and methodology - The population for the survey is the head of franchises in the metropolitan area (Seoul/Gyeonggi), which operates a restaurant franchise, and samples included a wide range of overseas/domestic brands and regions. The survey was conducted from August 1 to September 30, 2018 through the survey agency. The survey was conducted together with a telephone interview and a direct visit by the investigator. A total of 205 questionnaires were collected and retrieved, 4 questionaires containing missing information were excluded and 201 responses were used for analysis. Results - The results shows that franchisor's initial support services have significant positive effects on procedural, interpersonal, and informational relationship fairness, and continuous support services have significant positive effects on distributive, procedural, interpersonal, and informational relationship fairness. This study also shows that informational and procedural fairness have significant positive effects on performance(re-contract intention). Finally, continuous services a significant positive effect on performance(re-contract intention). Conclusions - The results show that franchisor make a manual, and should improve fairness through regular investigation whether support services was executed as promised in the manual after franchisee operation. In addition, information fairness and procedural fairness have been shown to increase performance(re-contract intention). These results mean that the franchisor's headquarters should provide product and service support for the merchant in accordance with the manual and management policy to reduce asymmetry in information and improve procedural fairness to enhance performance(re-contract intention).
