This study aims to develop a rich understanding of user goals in user-empowering information technologies which have been dominating part in the information systems environment. A particular focus is on users' goals in a social network site (SNS) which is a typical example of user-empowering technologies. Users conduct various activities in order to achieve diverse goals in SNS. Thus, investigating what goals users pursue in SNS will give insights into understanding the users. We employed the laddering interview technique and means-end chain approach. Interviews of 50 Facebook users were analyzed to produce a hierarchical goal map showing users' goal structure. The map contains 18 goals, including self-reflection, psychological stability, belongingness, improving productivity, and amusement as ultimate goals in SNS. In the map, there are varied routes from activities to ultimate goals in SNS; that is, a complex assembly consisting of activities and goals. The findings call the information systems research community to have more interests in diverse goals and values users seek with technologies.

This study aims to develop strategies to reinforce the roles of universities and volunteer service activities centering on promotion of their connections to communities and community-oriented volunteer service activities. First, for autonomous and continuing development of volunteer services, universities should have active connections with service organizations. Second, more specialized volunteer service programs should be developed. Third, as volunteer service activities are somewhat forced on college students, recognition for them should be improved. Fourth, as the quality of the service and academic achievement decrease, conditions for volunteer service education and programs should be made available. Fifth, for continuing participation in volunteer service activities, organized systems should be established.

This research investigates the impacts of information security (IS) culture and management leadership styles on employee's security behaviors (IS policies compliance, IS participation) in financial institutions. This study use the survey data collected from 236 employees of financial institutions. This research shows that IS culture has a positive effect on both behavioral intentions to comply with IS policies and the intentions to actively participate in information security activities. Transactional leadership has a positive impact on the IS policies compliance intentions and to participate in information security activities. In contrast, transformational leadership has a positive impact on the intentions to participate in information security activities, but not on the IS policies compliance intentions.

In the revision of the national curriculum, various creative activities and career activities are highlighted under the goal of fostering creative talent. Following the implementation of this policy, which is represented by creative activities, teachers are burdened with comprehensive responsibilities, such as planning and executing safety procedures and preventing accidents. Existing systems for teacher management had limitations that allowed only the provision of standardized information and management. The main purpose of this study is to help teachers manage their classes systematically through a class management system. The teachers' overall management system includes several functions, such as checking students' locations, registering students' reviews, or registering various kinds of activities for the creative experiential activities of the curriculum. This system not only helps teachers to systematically manage the creative experiential activities, but also allows teachers to share the history of their activities with each other. Furthermore, this system will be helpful in achieving the objectives of the revised curriculum.

Botnet is a type of dangerous malware. Botnet attack with a collection of bots attacking a similar target and activity pattern is called bot group activities. The detection of bot group activities using intrusion detection models can only detect single bot activities but cannot detect bots' behavioral relation on bot group attack. Detection of bot group activities could help network administrators isolate an activity or access a bot group attacks and determine the relations between bots that can measure the correlation. This paper proposed a new model to measure the similarity between bot activities using the intersections-probability concept to define bot group activities called as B-Corr Model. The B-Corr model consisted of several stages, such as extraction feature from bot activity flows, measurement of intersections between bots, and similarity value production. B-Corr model categorizes similar bots with a similar target to specify bot group activities. To achieve a more comprehensive view, the B-Corr model visualizes the similarity values between bots in the form of a similar bot graph. Furthermore, extensive experiments have been conducted using real botnet datasets with high detection accuracy in various scenarios.

This study empirically investigated the relationships among organizational culture, target costing, knowledge management activities, and corporate innovations. The results of this study showed that innovative and supportive culture positively affects the adoption degrees of target costing. According to the results, it was observed that target costing as well as innovative and supportive culture have a positive impact on levels of knowledge management activities(i.e., knowledge creation, sharing, storage, and application). It was also demonstrated that organizational culture has an indirect effect on activation of knowledge management activities through target costing. Thus, to enhance knowledge management activities, target costing must be aligned with appropriate types of organizational culture. In examining the impact of knowledge management activities on the frequencies of product and process innovations, no significant effect was found. Additional analyses that compare across three groups(i.e., low level group, middle level group and high level group in knowledge management activities) and between two groups(i.e., between high level group and middle level group or between high level group and low level group) were performed. The results of comparison showed that the degrees of product and process innovations are highest in high level group, but no significant differences are found in the degrees of innovations between middle level group and low level group.

In recent years, social media that has emerged with the development of network technology has changed the channels of information dissemination. The social Q&A community is a platform for knowledge-sharing activities in a question-and-answer manner based on Web 2.0. In knowledge-sharing activities, valuable new knowledge continues to be produced and will surely bring great benefits to individuals or businesses. In the social Q&A community, the user's subjective factors play a crucial role in influencing the user's continued use and participation in knowledge-sharing activities. In order for users to actively participate in knowledge-sharing activities in the community, it needs to grasp their subjective ideas. This study explores the issue of sharing knowledge by users of the social Q&A community "Zhihu", or how to drive community revitalization efforts from these. The three factors self-efficacy, self-development motivation, and social comparison tendencies were derived, and identify their relationship with knowledge-sharing activities and community-boosting efforts through empirical analysis. In addition, the influence of knowledge acquisition on knowledge provision was investigated through sense of reciprocity. Implications of the study findings and the future research directions were also discussed.

Purpose - The purpose of this study was to examine the effect of government R&D programs on firm innovation activities. Design/methodology/approach - This study analyzed survey data on innovation survey in Korea. To investigate our research hypothesis we used ordered logit regression analysis. Findings - This study unveils different effects of diverse government R&D programs on firm innovation activities. Most of government programs-R&D tax incentives, information/training, and marketing supports-have positive effects on management innovation activities and negative effects of the usage of procurement programs on management innovation efforts. Some government programs-R&D tax incentives, R&D grants, information/training-have positive effects on technological innovation activities. Research implications or Originality - This paper investigates the effects of diverse government R&D programs on technological and management innovation activities. We examine simultaneous effects of multiple government R&D programs rather than effects of independent R&D programs. This result can contribute to develop more effective government R&D programs to support firm innovation activities.

This Paper analyzed simultaneous activities of the time use survey by Korea National Statistical Office to use data mining‘s association rule. The survey of National Statistical Office in 1999 considered general analysis for simultaneous activities. But if we use the association rule, we can found the ratio of particular activities at the same time. And we found the probability that another activities practise if we act one particular activity. Using this association rule of data mining we can do more developed and analytical sociological study.
