One stream of the GDSS(Group Decision Support System) research is to investigate how GDSS affects decision performances of small groups according to task types, support features, meeting facilitation modes and meeting environments. But little study has investigated the effects of group member characteristics on group decision processes and outcomes depending upon whether GDSS is provided or not. To date, most GDSS studies have not controlled group member characteristics(e,g. personality, sex, decision style) in laboratory experiments. However, this study included the decision styles of group members as an independent variable. Therefore, this study investigated how differently members of two different decision styles perceive the use of GDSS in small group meetings through lab experiments. The two decision styles are feeling(F) style and thinking(T) style. We found that the effect of GDSS is a function of individual's decision style only in the communication thoroughness variable. The decision style is a statistically significant factor that can mediate the effects of the group support technology on the perceived communication thoroughness. Specifically, the GDSS is positively related to participants' perception about satisfaction on decision process, goal achievement, communication thoroughness, degree of influence-outward and effort for achieving meeting goals.

Data Envelopment Analysis(DEA), a non-parametric productivity analysis tool, has become an accepted approach for assessing efficiency in a wide range of fields. Despite of its extensive applications, some features of DEA remain bothersome. DEA offers no guidelines to where relatively inefficient DMU(Decision Making Unit) improve since a reference set of an inefficient DMU consists of several efficient DMUs and it doesn't provide a stepwise path for improving the efficiency of each inefficient DMU considering the difference of efficiency. We aim to show that DEA can be used to evaluate the efficiency of System Integration Projects and suggest the methodology which overcomes the limitation of DEA through hybrid analysis utilizing DEA along with machine learning.

Recently, the rapid development of information technology has brought enormous changes in education. Consolidation of communications and multimedia technologies are enabling the new educational paradigm such as distance learning and virtual education. Furthermore, many studies in the education engineering field report that teaching using multimedia technologies more enhances students' performance than the traditional instructor-teaching method. However, little research regarding the education using multimedia has been done in the MIS filed. None of multimedia-related studies could be found in the top-ranked MIS journals published in Korea for the last five years, and only a few studies were found even worldwide. In this regard, the purpose of this study is to investigate which features of multimedia software are most important to enhance the teaching results of students, From the previous research, we found out the specific features of the educational multimedia software which are considered to affect the students' performance, and defined the research variables related to those educational software features, And, based on the constructivism and motivation theory of the education engineering field, a theoretical research model and research hypotheses were developed. Perceived usefulness of the class and a student's perceived interests in the class were used as surrogate variables to measure teaching performance. Total 277 students participated separately in one of the two multimedia classes which have continued for three weeks. One was C programming language class and the other was multimedia CD-title development class. Each student listened for the multimedia session of the class using multimedia software and, at the end of the multimedia session, answered the survey questionnaire, The results of the study show that motivation to the class and the contents of education were statistically significant to the students' performance in the class. That implies, not only in the traditional instructor-teaching method but also in the multimedia class, that the contents of education itself and student's motivation to the class are most important to raise instructional results.

ERP system is a very popular tool for pushing management innovation and implementing an integrated information system. The purpose of this research is to investigate the relationship among the structure of production systems, types of implementation strategy, relative importance of competitive goals, information technology and culture level, and the efficiency from using the system. The data for this study were collected from 45 Korean manufacturing firms that have implemented ERP system. Research results confirm that the success factors include the top managements' strategic views and culture level related to new information technology. But the linkage between the structure of production systems and types of implementation strategy is proved to be very weak. Also control effect of types of implementation strategy on the efficiency of the organization is not strongly recognized. A summarized report of other findings is provided as well.

Recently there have been many efforts to develop hypermedia systems. Hypermedia applications can be categorized into process-oriented or contents-oriented. However, it is not a trivial task to build contents-oriented hypermedia in a systematic fashion. The contents-oriented hypermedia systems are developed primarily for the applications of marketing or information services. This paper proposes a methodology for a contents-oriented hypermedia system. Hypermedia contents are typically structured in the form of hierarchies. An index node can be used in order to give an effective access to this hierarchical structure. The proposed methodology employs three types of nodes(contents, index and function) and various navigation mechanisms, and helps design contents-oriented hypermedia systematically. Furthermore, various design techniques are proposed for maintaining contents-oriented hypermedia systems that have an evolutionary feature. Two real-life cases are illustrated to demonstrate the applicability of the methodology.

The resource-based theory addresses a new way of competition and the sustainability of advantages from competition, Moreover, Information Technology(IT) has interacted with other resources and gained the strategic importance. The central research task is to identify three relationships; (1) between organizational resources surrounding IT and IT performances, (2) between organizational resources surrounding IT and sustainable competitive advantages(SCA), and (3) between IT performances and the SCA. Results of the LISREL analysis show that firms must integrate IT into the other related resources of the organization and the management should consider comprehensive change management efforts rather than mere investments in technology to gain sustainable competitive advantages.

In order to investigate how firms appoint and manage successful CIOs, this study reviews previous literatures and finds major factors affecting the performance of CIOs, Eight factors are found and classified into two groups based on time horizon characteristics: ex ante factors before appointment and ex post factors after appointment. These eight factors are also re-classified into three groups based on the degree of interaction between CIOs and CEOs: CIO factors, CEO factors, and interaction factors between CIOs and CEOs. In order to investigate how these sub-groups affect the performance of CIOs, we have conducted case studies on 6 firms that are considered to have successful CIOs. The results indicate that ex ante factors, for instance, a factor whether the CIO is appointed from inside or outside of the firm, need to be carefully considered for the successful ex post management of CIO positions. This study derives several managerial guidelines and finally proposes a future research model for empirical studies.

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 computer game market has grown rapidly with numerous games produced all over the world. Most games have been developed to make gamers have fun while playing the games. However, there has been little research to address the elements of games that create the perception of being fun. The objectives of this research are to focus on which features provide fun, and then analyze these aspects both qualitatively and quantitatively. This study, through surveys with game players and developers, provides several inputs regarding what it is, that makes certain computer games fun. There are many common characteristics which fun games share, and through grouping and organizing these traits, then compiling the data for use in an AHP(Analytic Hierarchy Process), we measured the disparity in the 'fun' perception between game developer and game user.

It is important to investigate into the critical success factors(CSFs) of the CIO system in order to formulate a successful introduction strategy of the system. In an effort to provide the strategy, this research attempts to identify the CSFs of the system in the organizations of the private and public sectors in Korea. A result from the analysis of data collected shows that most organizations in Korea have already adopted, or are planning to adopt, the CIO system, implying that the value of the system is well recognized. Another result suggests that the success of the CIO system necessitate the CIO's abilities to recommend adequate IT and to apply appropriate IT solutions for the organization.
