Business-to-Business electronic commerce websites are a common form of inter-organizational systems that span organizational boundaries and enables organizations to exchange information in a seamless fashion. To reap the desired benefits it is important that the website be used in the intended manner. The level and extent of use of a business-to-business website depends partly on the inclination to use the website by the users in the primary organization and in the user organizations independently and the combined inclination of the organizations together. This combined inclination is referred to as the System Inclination, with dominance playing a key role. Each organization has certain characteristics of its own and may differ significantly in their inclination to use. It is important to analyze the factors that determine this inclination to use, so that organizations can adopt appropriate management mechanisms to control it. This paper proposes a framework to explain the organizational factors and their influence on the inclination to use a website, based on study of four Indian buyer-supplier dyads. Inclination to use is found to be influenced by factors like top management support, website characteristics, adequate support mechanisms, user group orientation towards electronic commerce and basic IT drive among the employees, at both the primary and user organizations.

The study was an exploratory research on the awareness of informatization and attitudes to information technology (IT) and its use among elderly women in a metropolitan area. The questionnaire survey was conducted to collect data on IT use or non-use of elderly women aged 60 or older in senior welfare centers in Seoul, Korea. The data on 343 cases were analysed using SPSS 21.0. As a result, the rate of internet use was relatively high and different according to socio-demographic factors, such as age. The elderly women's attitudes like the levels of awareness and expectation of informatization were positive. Elderly women learned to use IT for psychological, emotional reasons as well as for practical ones, and the satisfaction level of IT use was relatively high. Finally, most IT non-users were indifferent and ignorant about IT use. In addition, the dissatisfaction level of IT non-use was normal, but elderly women had a relatively positive expectation of IT use in the future. This study may contribute to understanding the diverse pictures of IT use and the digital divide in old age, and assist in the development of practical programs and policies for the informatization and welfare for older adults.

Advance of the Internet environment is applied not only to information search but also to the area of consumption behavior. Current research analyzes online use behavior and online information search of consumers in terms of users' perception. With the result of the research, it is noticed that promotion focus brings broader variation of information use behavior, and utilitarian value has a beneficial impact on the online exploratory information search. In addition, it is revealed that the more exploratory the information search is, the wider the range of online shopping information search is. Finally, people who have utilitarian shopping value showed more exploratory behavior in online search, especially for the search of informational products, than those who have hedonic shopping value. Present research is believed to improve practical influence of consumers' personality on online use behavior when customers purchase search products online. As a result, it would contribute to consumer research and marketing held online.

According to technology acceptance model(TAN) which is one of the most important research models for explaining IT users' behavior, on intention of using IT is determined by usefulness and ease of use of it. However, TAM wouldn't explain the performance of using IT while it has been considered as a very good model for prediction of the intention. Many people would not be confirmed in the performance of using IT until they can control it at their will, although they think it useful and easy to use. In other words, in addition to usefulness and ease of use as in TAM, controllability is also should be a factor to determine acceptance of IT. Especially, there is a very close relationship between controllability and ease of use, both of which explain the other sides of control over the performance of using IT, so called perceived behavioral control(PBC) in social psychology. The objective of this study is to identify the relationship between ease of use and controllability, and analyse the effects of both two beliefs over performance and intention in using IT. For this purpose, we review the issues related with PBC in information systems studies as well as social psychology, Based on a review of PBC, we suggest a research model which includes the relationship between control and performance in using IT, and prove its validity empirically. Since it was introduced as qa variable for explaining volitional control for actions in theory of planned behavior(TPB), there have been confusion about concept of PBC in spite of its important role in predicting so many kinds of actions. Some studies define PBC as self-efficacy that means actor's perception of difficulty or ease of actions, while others as controllability. However, this confusion dose not imply conceptual contradiction but a double-faced feature of PBC since the performance of actions is related with both self-efficacy and controllability. In other words, these two concepts are discriminated and correlated with each other. Therefore, PBC should be considered as a composite concept consisting of self-efficacy and controllability, Use of IT has been also one of important areas for predictions by PBC. Most of them have been studied by analysis of comparison in prediction power between TAM and TPB or modification of TAM by inclusion of PBC as another belief as like usefulness and ease of use. Interestingly, unlike the other applications in social psychology, it is hard to find such confusion in the concept of PBC in the studies for use of IT. In most of studies, controllability is adapted as PBC since the concept of self-efficacy is included in ease of use explicitly. Based on these discussions, we can suggest perceived use control(PUC) which is defined as perception of control over the performance of using IT and composed of controllability and ease of use as sub-concepts. We suggest a research model explaining acceptance of IT which includes the relationships of PUC with attitude and performance of using IT. For empirical test of our research model, two user groups are selected for surveying questionnaires. In the first group, there are freshmen who take a basic course for Microsoft Excel, and the second group consists of senior students who take a course for analysis of management information by Excel. Most of measurements are adapted ones that have been validated in the other studies, while performance is real score of mid-term in each class. In result, four hypotheses related with PUC are supported statistically with very low significance level. Main contribution of this study is suggestion of PUC through theoretical review of PBC. Specifically, a hierarchical model of PUC are derived from very rigorous studies in the relationship between self-efficacy and controllability with a view of PBC in social psychology. The relationship between PUC and performance is another main contribution.

The purpose of this study is to investigate the effects of home informatization on the family resource management. For this purpose we analyze the level of home informatization focused on the Internet use and it's effects on the family resource management through time management and financial management. Data were collected from 582 housewives who use the Internet at home. The results show that home informatization through the Internet use has changed family resource management totally. It contributes to improve planning and efficiency of resource management, but simultaneously it causes the imbalance of resource management. And the Internet use of housewives also affects time allocation and household expenditure. These changes depend on socio-demographics variables, home informatization related variables, and personal resource variables. The results show that the ability to manage time and finance have much more importance to improve the level of planning and efficiency and to decrease the level of imbalance in managerial subsystem. The results of this research suggest several implications for public policy.

Among Korea's content industries, the game industry is growing in size to the extent that it can be said to be a representative export-benefiting industry. Accordingly, many users are immersed in the game, and furthermore, they are addicted. This study aims to derive factors for social game users to continue to use by identifying the factors of domestic social network game users' attachment to social network games and empirically studying the causal relationship between these factors and the intention to continue to use them through immersion and addiction. To this end, a research model was presented that applies the main variables of the attachment theory of social network game users to games. The research model of this study surveyed general college students at S University in Seoul who tended to use social network games. As a result of the study, first, it was found that perceived stability had a significant effect on immersion and addiction. Second, it was found that perceived avoidance had a significant effect on immersion and did not have a significant effect on addiction. Third, perceived anxiety was found to have a significant effect on immersion, and it was found that it did not significantly affect addiction. Fourth, it was found that immersion did not significantly affect addiction, and it was found that it had a significant effect on continuous use intention. Fifth, addiction was found to have a significant effect on the intention to continue use. Through this, social network game users' attachment to games can provide useful implications for social network game companies to become attached to existing consumers, spreading social network game users, and improving the possibility of continuous use.
