The Expectation Confirmation Model (ECM) of information systems investigates the continued information systems usage behavior. This paper expands the original post-adoption beliefs and searches the applications in the emerging hedonic information systems. Previous IS researches focused on the organizational environments. However as the information technology (especially internet) evolves, information systems have not only emerged for the organizations but also for the individual users, such as internet portals, internet communities, on-line games etc. These information systems so called Hedonic Information Systems aims to provide self-fulfilling value rather than instrumental value to the users. Researches in other disciplines, including marketing and consumer behavior research, illustrate that the hedonic and utilitarian perspective of goods and services have different influence on the consumer behavior. Goods and services used to be classified into either hedonic or utilitarian aspect but now they may belong to both aspects simultaneously. Moreover consumer's goals or tasks have both hedonic utilitarian aspects. When a consumer makes a decision to purchase or repurchase goods or services, he/she compares the hedonic and utilitarian perspectives of goods to find most suitable ones to satisfy their goals/tasks. Finally, consumer's behavior is determined by the trade-off between what the goods can provide to the consumers and in what extent the goods fulfill consumer's purchase behavior. Consumer also shows that the salience of hedonic perspective is relatively greater when consumer decides which of several items to give up (forfeiture choices) than the time when they decide which item to acquire (acquisition choices). Some researches in MIS discipline have found out that the information systems also have both hedonic and utilitarian perspectives. The decision process of whether to use information systems or not is similar to that of a consumer's decision of purchasing or repurchasing goods or services. However most of researches in MIS tend to focus on the extrinsic motivation variables which only cover the utilitarian perspective of information systems. It is only recent that researches start to investigate the intrinsic motivation variable - Perceived Enjoyment - for the hedonic perspective. Considering the consumer's purchasing decision process, users of information systems evaluate the systems through balancing between intrinsic (hedonic) and extrinsic (utilitarian) variables according to their main tasks or tendencies. This paper proposes a model that is based on the ECM of IS Continuance model modified from Expectation Confirmation Model to fit into the continued usage of information system. It first started from the decision process regarding hedonic and utilitarian perspectives in the consumer behavior literatures. The model deals with continued usage of information systems beyond the mere technology adoption as in most of the previous MIS researches. This research is particularly important to the hedonic information systems, because their business model depends on the frequent usages rather simple adoption at the beginning. Because the basic model only considered the extrinsic motivations (perceived usefulness) to explain the users' behavior and as the information systems can have both hedonic and utilitarian dimensions, it should consider both perspectives. Therefore, this newly proposed model considers intrinsic variable (perceived enjoyment) as well. Since the individual user can have a preference on either aspects that is between the hedonic and utilitarian perspective depending on his/her main tasks or goals, some variables (Hedonic Orientation and Utilitarian Orientation) meaning the extents of users' pursuing from the information system were additionally studied.

This study was to investigate the moderating effect of the protective factors in the relationship between impulsivity and suicide behavior of elementary school students. This study surveyed total 573 elementary school students located in Seoul. They completed survey questionnaires of impulsivity, suicide behavior and protective factors. Collected data was examined using correlation analyses and hierarchical multiple regression analyses. First, a total of 29(5.1%) students reported suicide plan, 17(3.0%) students reported suicide attempts and the rate of suicide behavior was 7.1%(n=41). Second, there was a negative relationship between impulsivity and protective factors and a positive relationship between impulsivity and suicide behavior. Also, it was found that the protective factors(individual factor, family factor, peer factor, school factor) moderated the relationship between impulsivity and suicide behavior of elementary school students. The implications and limitations of this study were discussed.

The purpose of this study is to determine the effect of innovation-oriented organizational culture on organizational members' innovation behavior, and to confirm the sequential mediating effect of the boss's coaching leadership and the basic psychological needs of organizational members. For this purpose, an online survey was conducted targeting 377 office workers who had been working with the same boss for more than 6 months. The collected data was analyzed using Hayes' SPSS PROCESS Macro. The results of this study are as follows. First, it was confirmed that the relationship between organizational culture and innovative behavior was statically significant. Second, it was confirmed that coaching leadership and basic psychological needs sequentially mediate in the relationship between organizational culture and innovative behavior. In other words, the innovation-oriented organizational culture does not directly affect innovative behavior, but rather leads to the exertion of coaching leadership by boss, and coaching leadership promotes more innovative behavior by influencing the satisfaction of members' basic psychological needs. This is meaningful as a basic study on how environmental variables, such as organizational culture and superior leadership, affect individual motivational variables, desire, and thus affect individual behavioral variables. In addition, based on the results of this study, academic and practical implications were discussed, and limitations of this study and suggestions for follow-up studies were discussed.

The purpose of this study was to examine the relationship between toddler's negative emotionality, parenting behavior, and the moderating roles of mother's personality. The participants in this study consisted of 221 mothers of toddlers (aged from 18 to 35months) in Seoul. The participants completed questionnaires on toddler's negative emotionality, their personality and parenting behavior. The collected data were mainly analyzed by descriptive statistics, t-test, one-way ANOVA, Duncan test, Pearson's correlation and the multiple regression analysis. The main findings of this study were as follows. First, there was a significant difference in the negative parenting behavior according to the mother's educational level. Second, relations between individual variables and parenting behavior were analyzed. As a result, number of children, mother's age, toddler's negative emotionality, and mother's personality were significantly correlated with parenting behavior. Third, through the analysis of the moderating effect of the mother's personality on the relationship between the toddler's negative emotionality and parenting behavior, it was found that interactions between the mother's neuroticism and the toddlers' negative emotionality affected the mother's warm parenting behavior. And interactions between the mother's extraversion and the toddlers's negative emotionality affected the mother's rejection parenting behavior. The results of this study provide basic data to support mothers' positive parenting behavior.

The purpose of the study was to examine if individual characteristics and experiences related to smoking behavior identified from the literature were significantly associated with behavior-specific cognitions and affect in the same way as presented in Pender's Revised Health Promotion Model(Pender, 1996). The subjects selected for this study were 400 college students enrolled in more than 10 colleges located in Seoul and Kyunggi-Inchon province. According to the study results, personal factors (i.e., perceived health status, the past history of disease, and symptoms related to smoking) and related behavior (i.e., the degree of alcohol consumption, and exercise) are significantly associated with behavior-specific cognitions and affect (i.e., perceived barriers to smoking cessation, perceived self-efficacy, and perceived benefits of smoking cessation). The canonical correlation between two groups of variables was .59, and it turned out to be statistically significant. Thirty-four percent of variance of the relationship between two group of variables was explained by two canonical variates which turned out to be significant in the study results. The result could be interpreted from the view of psycho-social area as follows: overall, this study includes important variables which explain the association between two groups of variables.

Emerging attacks aim to access proprietary assets and steal data for business or political motives, such as Operation Aurora and Operation Shady RAT. Skilled Intruders would likely remove their traces on targeted hosts, but their network movements, which are continuously recorded by network devices, cannot be easily eliminated by themselves. However, without complete knowledge about both inbound/outbound and internal traffic, it is difficult for security team to unveil hidden traces of intruders. In this paper, we propose an autonomous anomaly detection system based on behavior profiling and relation mining. The single-hop access profiling model employ a novel linear grouping algorithm PSOLGA to create behavior profiles for each individual server application discovered automatically in historical flow analysis. Besides that, the double-hop access relation model utilizes in-memory graph to mine time-sequenced access relations between different server applications. Using the behavior profiles and relation rules, this approach is able to detect possible anomalies and violations in real-time detection. Finally, the experimental results demonstrate that the designed models are promising in terms of accuracy and computational efficiency.

The mobile market has introduced unprecedented shopping opportunities to customers and is expected to grow rapidly over time. However, little is known about how customers make purchase decisions in the mobile market. The purpose of this study is to investigate the drivers of mobile VOD purchases and to deliver valuable insights to mobile business operators. We focus on the purchase of VOD contents that have to be purchased and consumed using mobile devices and examine how individual-level purchase decisions are determined by three factors: perceived usefulness, usage behavior, and privacy concern. We obtained the panel data from a leading market research company that contains the mobile logs and survey results. Our main results suggest the followings. First, the perceived usefulness affects customers' mobile VOD contents purchases positively whereas the usage behavior exerts no influence on mobile contents purchases. Moreover, the privacy concern lowers the positive effect of perceived usefulness on mobile content purchases; however, it enhances the effect of the usage behavior on mobile contents purchases. These empirical findings indicate that mobile business operators should pay more attention to potential differences in perception and behavior using mobile devices and keep in mind that the privacy concern plays an additional key role in driving mobile contents purchases.

The purpose of this study is to classify men in their 20s by their sex role attitudes, and to study their appearance management behavior and inner characteristic variables such as socio-cultural attitudes on appearance and bodily image, which are expected to influence the appearance management behavior of each classified group. For this, a survey of 393 males in the 20s in Seoul and metropolitan areas was conducted. Factor analysis, Cronbach's alpha coefficient, and F-test were conducted on the data. First, as a result of analysis on sex role attitudes, four groups were categorized: Masculinity, Femininity, Androgyny and Undifferentiation. Second, the analysis of individual variables resulted in appearance management behavior being separated into five categories: Interests in fashion, Proper choice of clothing, Importance of bodily attractiveness, Pursuit for personality and Complementation of physical weaknesses. The socio-cultural attitude on 'appearance' was sub-categorized into Internalization, and Awareness, while 'body image' was divided into Cognitive behavioral and Affective aspects. Regarding differences in socio-cultural attitudes for appearance, body image and metro-sexual lifestyle attitudes, the androgyny group produced the highest scores. Based on these results, it can be concluded that people who take care of their physical appearance, cope effectively with social and circumstantial requirements for happiness and success, and respond flexibly and affirmatively.

Impulse buying has been considered a pervasive and distinctive phenomenon in the modern lifestyle and has been receiving increasing attention from consumer researchers and theorists. In the modern marketplace, spontaneous urges to buy and consume often compete with the practical necessity to delay the immediate gratification that purchasing provides. The purpose of this study is to conceptualize and test the framework of impulse buying behavior for fashion products using structural equation model. Data were obtained from 413 students attending universities during schedules classes in Busan. Analysis of the data, utilizing AMOS 4.1, supported most of the predictions. The results showed that situational variable(time available) and individual variable(fashion involvement) have direct effects on consumers' shopping emotions, including positive and negative emotion. Positive emotions had effects on all types of impulse buying(planned impulse buying, reminded impulse buying, and fashion-oriented impulse buying), while negative emotion affected two types of impulse buying(reminded impulse buying and fashion-oriented impulse buying). These emotional experiences influence impulse buying behaviors for fashion products serving as critical mediators. The findings suggest that time available and fashion involvement are good predictors mediated by shopping emotion to impulse buying behavior for fashion products. The implications of this research for future work on the shopping emotion and impulse buying behavior are discussed.
