Nowadays, domestic hospital business is under the great threat from the environmental changes caused by the entrance of foreign hospitals and the technical changes related to information systems. In such a situation, to enhance the competitive edge of a hospital, it is needed to set up a competitive strategy and to construct an efficient information systems to back up the competitive strategy. If the hospital information systems(HIS) is consistent with a competitive strategy backing up, the competitive force of a hospital will be enhanced. For this respect, the influence of the competitive strategy and HIS construction environments on the performance of HIS was examined. The results suggested that if a HIS should be newly constructed or should be restructured, it is necessary to select construction environments of HIS such as physical environments, development methods and development tools to support functional strategy effectively based on the competitive strategy adopted by a hospital.

The exponential growth of information on the web far exceeds the capacity of present day information retrieval systems and search engines, making information integration on the web difficult. In order to overcome this, semantic web technologies were proposed by the World Wide Web Consortium (W3C) to achieve a higher degree of automation and precision in information retrieval systems. Semantic web, with its promise to deliver machine understanding to the traditional web, has attracted a significant amount of research from academia as well as from industries. Semantic web is an extension of the current web in which data can be shared and reused across the internet. RDF and ontology are two essential components of the semantic web architecture which support a common framework for data storage and representation of data semantics, respectively. Ontologies being the backbone of semantic web applications, it is more relevant to study various approaches in their application, usage, and integration into web services. In this article, an effort has been made to review the research work being undertaken in the area of design and development of ontology supported information systems. This paper also briefly explains the emerging semantic web technologies and standards.

본 연구는 독립된 학문분야로서의 정보시스템이 갖는 표준교육과정의 핵심구조를 파악하고 이를 기초로 국내 정보시스템 관련학과의 교육과정을 정보시스템의 표준교육과정과 비교분석하고자 하였다. IS 2002 표준교육과정의 핵심교과목을 기초로 국내 정보시스템 관련학과의 교육과정을 비추어 보았을 때 전체 교육과정 가운데 약 58%만이 이에 해당하였다. 이는 곧 독립된 학문으로서의 정보시스템이 아직 국내에서 충분히 학문으로서 독립성을 확보하지 못하고 있음을 나타내고 있다. 다만 핵심교과목에 있어서는 편중됨이 없이 대체로 각 영역에 고루 편성되어 있는 것으로 나타났다. 아울러 정보시스템이 경영학을 모태로 출발하였음을 나타내는 증거가 인접학문의 분석을 통해 확인할 수 있었다. 다양한 인접학문 가운데 거의 독보적으로 70% 이상의 교과목이 경영학분야(회계학 포함)로 편성되어 있음을 볼 수 있었다. 이는 한편으로 정보시스템이 경영학에 의존하는 바가 커서 경영학으로부터 독립하여 독자적인 학문영역을 구축하는데 장애가 되고 있음을 나타내기도 한다. 국립대학 및 상위권 대학을 중심으로 많은 대학에서 독립된 학과(학부)를 개설하는 대신에 경영학과(학부) 내에서 몇 개의 관련 교과목을 편성하는 수준으로 전공을 운영하고 있는 것도 이러한 현실을 반영하고 있는 것으로 보인다.

Factors influencing the success or failure of information systems(IS) have been discussed in many literature. However, little theoretical development or empirical research has examined effectiveness of hospital information systems(HIS) This study set the research model of influencing factors and consequences of HIS through theoretical studies based on Management Information Systems, and then empirically tested several hypotheses related to this model. Based on a sample of 274 respondents who participated in dealing with the HIS, this research used a multiple regression analysis to test the research model. The results of this study are as follows: system quality, information quality and support of top management are statistically significant influence on user satisfaction. Service quality is a partially significant influence on user satisfaction. Hypothesis 5, proposing that computer self-efficacy would relate positively to user satisfaction, was not supported by the questionnaire results. Based on these results, system quality, information quality and support of top management are very important variables for IS success. And the study's findings indicate DeLone and McLean's model is correct in proposing that the indirect relationship between influencing factors and organizational effectiveness, mediated by user satisfaction, is an important one.

The increasing importance of IT rose to the top of list of marketing managers' key concerns and IT has been used widely in performing various marketing activities and decisions. However, little was known about how to employ IT in various marketing activities and how to use IT as a strategic marketing means. Also, comprehensive empirical studies have rarely been conducted. This study examines the effectiveness of integrative use of marketing and IT. More specifically, this study attempts to identify the factors that influence the effectiveness of marketing information systems. The manufacturing firms listed in the Korean Stock Market were surveyed. the major findings of this study are as follows. First, the variables of organizational characteristics such as formalization of decision making cooperation between marketing function and IS function, and degree of decentralization were significantly related to the success of marketing information systems. The variables of user highly associated with the success of marketing information systems. Second, it was also found that the support capability of marketing information systems is the major factor of the effectiveness of marketing information systems. Third, the variables marketing function and IS function, and ratio of export sales to total sales were three variables such as marketing knowledge of marketing managers, cooperation were the main factors to affect the users' satisfaction with the information system. These results imply that, in order to increase the effectiveness of marketing information systems, a firm should enhance a cooperation between marketing function and IS function, diversify the support capability of IS, and strengthen the computer mind and computer knowledge of end-uses.

In response to the significant COVID-19 outbreak, countries have enforced the use of E-learning systems as an alternative to traditional learning; to contain the virus and minimize the infection rate while maintaining the continuity of the learning experience. However, the effective adoption of E-learning systems requires a well-understanding of critical factors, especially in times of crisis. In this regard, this study intends to assess the success of the E-learning system adoption by Higher Education Institutions (HEIs) during the crisis of COVID-19 by utilizing the Information Systems Success (ISS) model. This study's adopted model consists of nine interdependent dimensions, namely: Technical System Quality, Information Quality, Service Quality, Learner Quality, Perceived Satisfaction, Perceived Usefulness, System Use, Intention to Use, and System Success. An electronic survey was distributed among higher education students from different universities in Saudi Arabia to explore each model's dimension. Structural Equation Modeling (SEM) has been applied via SmartPLS software to test the causal relationships between dimensions. This study's main results revealed that students' Service Quality, Learner Quality, and the Intention to Use by students are essential drives for E-learning System Use during the Covid-19 pandemic. Meanwhile, the Intention to Use the system is significantly influenced by Perceived Satisfaction and Perceived Usefulness dimensions. Further, Perceived Satisfaction, Perceived Usefulness, and System Use are interdependent, and all three have a significant positive impact on E-learning System Success.
