In this study, we verify the relationship, which is presented by ISO/IEC 15504, between the assessor`s competence and the efficiency of assessment. The ISO standard has been developed by many formal trial experiences for the software process assessment. The software process assessment determines the process capability, and makes the software process improvement possible in the development cycle. In the field assessment, third-party and team-based assessments are generally recommended. Therefore assessors` competences are essential to achieve the effectiveness and the efficiency of assessment. Survey data are collected from the third-party process assessment of a real IT industry, and the analysis is done by a causal modelling technique - PLS. Some findings are as follows. Depending on assessors` SE experiences, effects of the assessor`s competence are existed, and their standard knowledge and assessment skill are effected each other. And the efficiency of assessment depends on the assessor`s competence. In addition, the power analysis is presented and future research is suggested, because of many limitations of this study.

The Web has become an excellent source for gathering consumer opinions. There are now numerous Web sites containing such opinions, e.g., customer reviews of products, forums, discussion groups, and blogs. This paper focuses on online customer reviews of products. It makes some contributions. Especially it proposes minimalism and chunking framework for analyzing and comparing consumer opinions of competing products. Users are able to clearly see the strengths and weaknesses of each product in the minds of consumers in terms of various product features. This comparison is useful to both potential customers and product manufacturers. For a product manufacturer, the comparison enables it to easily gather marketing intelligence and product benchmarking information. In this paper, we only focus on mining opinion/product features that the reviewers have commented on. Five types of online review presentations are presented to mine such features. Our experimental results show that these techniques are useful to identify customers` opinions and trends.

Ubiquitous tourism information systems are more and more required to provide cultural contents comprising material heritage, performing art, folk tradition, handicraft or customs of everyday life, along with traditional tourist information about hotel facilities and infrastructure. This study attempts to investigate the effect of tourists` hotel preference attributes in terms of their satisfaction with ubiquitous tourism service. In so doing, 145 questionnaires were used to analyze the satisfaction of u-tourism service and the hotel preference attributes through the field survey. The questionnaires were collected from hotel employees who had experienced the ubiquitous tourism service. It is found that some of hotel-preference attributes positively influence u-tourism satisfaction but not all of them did. Service and differentiation attributes had an impact to u-tour and u-hotel function. And beverage attributes, to u-tour function, and convenience attributes, to u-hotel function. These findings mean that the hotel built u-tourism infrastructure gain a competitive advantage than the otherwise hotel.

This study analyzed the effects of smart phone using for business on work performance in the field. We classified functional and practical aspects of smart phone affecting employee`s work performance through former studies. As independent variables, we selected portability of equipment, rapidity of information and ease of use for functional side, and selected fit to work and subjective norms for practical side. And dependent variable was work performance. We also suggested that innovation resistance would be a moderator. The results showed that the effect of work performance was influenced by portability of equipment and fit to work. However, hypotheses on moderating effects of innovation resistance were not supported. This study made a discrimination in terms of an application phase of smart phone as against former studies. The results of this study will provide practical implications for related enterprises in the field to develop ways of using smart phone as an effective strategy.

DOI : 10.5859/KAIS.2011.20.2.81
Group features such as group cohesion and consistency on appropriation(COA), which have been constructed through social interactions, should be noted for characterizing online game, especially, clan based massively multi-players online game (MMOG). This study attempted to identify the relationship between group characteristics and users` effectiveness of MMOG considering group experience. For this purpose, a research model was suggested: group cohesion and COA are variables for explaining group features, perceived use control is a variable for individual competency of playing MMOG, and perceived winning and perceived enjoyment are dependent variables. Moreover, group experience was included as a moderating variables for two relationships, group cohesion-preceived winning and COA-perceived winning. For the validation of this research model, 100 users for Sudden Attack which is one of very well known MMOG games were surveyed by questionnaires. Before survey, they were grouped into 10 teams and were played over ten times by team for perceiving group consciousness. In result, most hypotheses were statistically supported except the relationship between group cohesion and perceived winning.

The purpose of this paper is to present an overview of the characteristics of the e-sports business at a crucial point in the era of information and knowledge. That is, an investigation was conducted surrounding the key success factors of e-sports as a newly growing industry, and the relationship between the key success factors and the usage effect. In order to do this, the key success factors were extracted from interviews with e-sports experts in conjunction with a survey that was conducted to gather empirical data. The key points of the statistical analysis of the survey are as follows. First, the success factors of a policy do not have a significant effect on the usage. Second, some administrative success factors of the e-sports business include the distribution of e-sports in the form of franchise chain, the establishment of policies to prevent the excellent members of e-sports from seceding, making a good impression as a high-class sport, the frequent notice of the break-even point, and educating people on how to use the e-sports machine. Third, the development and distribution of excellent e-sports software was analyzed as a technical success factor of the e-sports business. Finally, there is no doubt that results of this study can be used to facilitate the growth of the e-sports business as a new industry related to the IT industry.

The Sido.Saeol system, a local government information system cost too much for having been designed and developed during last four years but the effectiveness of this system is still open to doubt. Also maintenance cost is still too high and become increasing year by year. To find out the reasons and to suggest how to solve these problems, a service quality of an Sido Saeol system and the public servant`s job satisfaction were investigated based on the Delone and McLean`s updated IS success Model(2003). To investigate of the effectiveness of the Sido Saeol system, 8 variables are analyzed to test 3 main hypothesis. After all the analysis, we found that Sido.Saeol systems have many aspects to be improved for system use and job satisfaction and have to be revise in the aspects of system qualities.

The use of mobile office systems has been expanded due to the smartphones` rapid diffusion in Korea, and it has brought a new work environment that is different from traditional working patterns. In this study, the unique attributes of mobile office systems, such as ubiquity, usefulness, complexity, and insecurity, are examined along with the impact of these attributes on work overload and job stress. Based on transaction-based model of job stress, organizational support was applied as a stress inhibitor and also the moderator between work overload and job stress. The findings of this study show that ubiquity increases usefulness of mobile office systems; complexity increases both work overload and job stress; and insecurity increases job stress. Surprisingly, usefulness increases job stress, which means employees who perceive the efficiency of mobile office systems higher may feel more job stress. Organizational support for mobile office systems significantly shows the moderating effect, but no direct mitigating effect on job stress. The theoretical and practical implications in order to mitigate the side effects of mobile office systems based on the research findings are thoroughly discussed.

IT governance is an integral part of enterprise governance and consists of the leadership, organizational structures, and processes that ensure organization`s IT decision making for achieving organizational goal. Most firms have failed to resolve the balance in building IT governance. The challenge is to align IT strategy with business strategy in establishing and implementing effective IT governance. The purpose of this study is to find out the relationship between IT governance implementation factors and IS effectiveness, and the moderating effect of strategic alignment of IS strategy with business strategy on IS effectiveness. IT governance implementation factors consist of IT vendor management, IT human resource management, and IT infrastructure. Strategic alignment was measured as the alignment between business strategic orientation and IS strategic orientation that used in the research of Chan et al.(1997). In the relationship between three IT governance implementation factors and IS effectiveness, the results of multiple regression analyses showed that IT human resource management is an important determinant to influence IS effectiveness. The additional analysis using multiple regression showed that strategic alignment of IS strategy with business strategy has moderated the relationship between IT governance implementation factors and IS effectiveness.
