The diffusion of the mobile telecommunication service in a country could be affected by the diffusions of the services in her neighbor countries. Previous studies on the diffusions of the telecommunication service among countries have been mainly focussed on the comparison after individual diffusion estimation. However, it would be natural to think the diffusion of the mobile telecommunication service in one country could affect to and be affected by the diffusion of the mobile telecommunication service in her neighbor country. In this study, we have applied the multinational diffusion model to model the crossnational effect in the diffusion of the mobile communication service in China, Korea, U.S., Japan, and Hong Kong. Among these 5 countries China is the latest country to adopt the mobile communication service, and we were interested in whether the diffusion of the mobile communication service in Korea, U.S., Japan, or Hong Kong has affected the diffusion of the mobile communication service in China or not. In our application result, the diffusion of the mobile communication service in China has been affected significantly by those in all of the 4 neighbor countries.

국내에서 활발히 연구되고 있는 모바일 RFID 서비스는 기존의 RFID 서비스 방식과는 다르게 이동통신망을 기반으로 하여 제공된다. 모바일 RFID 서비스는 무선환경을 통해 모든 서비스를 제공받기 때문에 전송률과 오버헤드로 인해 효과적인 서비스가 어렵다. 또한 단말의 처리능력, 화면 크기 데이터 저장 등도 한계를 가진다. 모바일 RFID 네트워크는 이와 같은 환경적 한계와 더불어 서비스 제공 방식도 request-response 방식으로 제공되므로 서비스의 구성이나 생성 과정이 복잡해지는 문제점을 가진다. 이에 본 논문에서는 모바일 RFID 네트워크의 환경적 제한을 해결 하는 동시에 보다 효과적인 서비스 제공을 가능하게 하는 서비스 구성 방식을 제시한다.

There are big differences in six sigma projects between manufacturing processes and transactional/service processes. This paper analyzed the differences between the two areas by examining 18 six sigma case studies in Korean companies. To characterize six sigma case studies, step-by-step questions and check criteria were developed based on 12 step DMAIC methodology. On the basis of those characterized data, the differences between two areas were analyzed. Significant differences were found in the number of CTQs, validation of measurement systems, methods to determine improvement objectives, the methods to elicit improvement plans and types of control systems. The most significant difference was that statistical tools were widely used in manufacturing processes, but qualitative tools were used in transactional/service processes during improvement phase.

The aim of this study is to assess the impacts of service properties, price expectancy, social influences, and switching costs on adoption intention of 4G in Vietnam. The research model was established by the theory of diffusion of innovation, technology acceptance model, service quality, social influences and switching costs. The result from customers using telecommunication services in Vietnam shows that adoption intention of 4G is affected directly by perceived usefulness, personal innovativeness, price expectancy, social influences, prior service quality and switching costs. Whereas, switching costs have negative effect on adoption intention. Other factors such as personal innovativeness, perceived ease of use and prior service quality have an indirect effect on adoption intention of 4G.

최근 IT Service 에는 SNS 즉, Social Network Service가 주를 이루고 있다. Facebook, Twitter 등 자신의 일상을 친구들과 공유하는 웹 기반 Service가 사람들에게 많이 이용되고 인기를 끌고 있다. SNS system이 일반화되어 가면서, 보다 전문적이고 국소적인 분야에 특성화되어 발전되어 나갈 것으로 보이며, 이러한 SNS 시스템을 최적화 하기 위해 SNS 프로토타입을 직접 개발해 볼 필요가 있다. 본 논문에서는 학교 캠퍼스 정도 규모의 서비스를 위한 웹 기반의 SNS들이 어떠한 구조로 이루어져 있으며, 어떠한 원리로 동작하는지 알아보고, Server, DataBase, PHP 를 이용하여 웹 기반 SNS 시스템을 직접 구현하고 시연해 봄으로써 SNS System에 대한 이해를 해보고, SNS system에 대한 향후 방향을 모색해 보도록 한다.

IPTV Service was launched with great expectation, but it is having difficulty due to the low number of subscribers and contents. In addition, the study of IPTV is still in its infancy and most of previous studies are only focused how IPTV is adopted and spread. In this study, we defined that resistance is the users not tend to accept IPTV service, and analyzed factors affecting resistance which are Innovative characteristics, User characteristics, Service characteristics and proposed implications for IPTV service vitalization. The results that relative advantage, complexity, attitude of an existing product, contents, cost, innovativeness have significant effects on resistance to IPTV.

Objectives: This study aimed to analyze the papers in the Korean Journal of Health Service Management (KJHSM) (2007-2018) in order to identify the research trends and aid the future development of healthcare-related research. Methods: Data collection was conducted from September 1-30, 2019. The KSHSM website and Lorea Citatin Index (KCI) electronic database provided 605 copies of original text. Results: Of these, 538 studies are original articles and 7 studies are review articles; 23.7% of the studies presented conceptual framework, 58.4% implemented convenience extraction, and 64.7% collected data using questionnaires. 29.3% of key words were included in the healthcare service, and 48.5% were excluded from the submission field. Conclusions: For the qualitative improvement and development of the journal, it is necessary to consider the relevance of refinement of the methodological approach, segmentation in the field of submission, and selection of keywords.

Recently, with the introduction of social network services, studies that try to make use of them for the various purposes have been actively investigated. In order to proceed with the research that takes advantage of social network services, it is necessary to review the relevant literature and to identify trends in researches. However, the researches of social network are massive amount, so to review the huge amount of relevant research literature is a very difficult task. Therefore, in this study, we analyze systematically the tendency of research related to social network service focusing on Twitter. Especially, we use the SLR (Systematic Literature Review) technique for systematic literature survey and analysis. For the literature survey, we select korean literature resource sites and 243 studies of literature that are surveyed. Studies and analyzes on Twitter in a variety of research studies were also using Twitter data that way beyond the simple question directly.

Recently, Service-Oriented Architecture(SOA) is on the rise to reduce the complexity of IT infrastructure, minimize cost for maintaining it and maximize the productivity and flexibility in business. SOA increases the adaptability by loosely coupling and it's main feature is that three elements such as service provider, service requester and service registry are connected with each other systematically. These make difficult to adopt traditional development methodologies to implement SOA. In this paper, we suggest a service-oriented development process with regard to the aspect of service provider and service requester. The process consists of six phases and each phase sets up with guidelines and artifacts. It can choose the process type along with the goal in Development Planning.

ASP (Application service provider) as a new type of information systems service has been popular recently and has taken a much attention of information systems professionals and researchers. One stream of the research on ASP performed by IS community dealt with utilization and benefits of ASP systems use. The other researchers argue the importance of ASP vendors' capability to provide users with appropriate services. Kern, Lacity and Willcock (2002) summarized the components of core competency of service providers based on their extensive case studies on application service providers. Also, Levina and Ross (2003) developed a value delivery process of application service Providers in their case study This study is developing Prepositions and an empirical model based on the theory of core competency from strategic management study. The dimension of core competency is composed of management competency, technical service competency and customer service competency. Each dimension is made up of competency items derived from previous studies and adapted by professionals in ASP industry. The validity of the dimensions and items in each dimension has been checked with factor analytic method for empirical test. The core competency dimensions are correlated with performance factors of application service providers including growth of revenue, asset and customer base.
