Web 2.0 paradigm and technologies allow users to contribute their information voluntarily and actively to online community. This paper aims to investigate key determinants of information contribution in online communities. We come up with the research model and proposed hypotheses on the basis of intensive literature review on motivation theory, information literacy, and self expression. Using survey response date collected from those who have ever experienced in uploading or providing information on online community such as social media. A total of 262 survey responses were used to test research hypotheses. The results show that self expression motive influences on information representation capability(IRC) and information contribution. The impact of Information literacy on IRC is found to be significant, and IRC is positively related to information contribution. In addition, approval motive is proven to be key determinant of IRC and information contribution. Some practical implications of these findings are discussed.

SCM system is a strategic cooperative that organically integrates all supply chains to improve the performance of a company. For effective SCM system, emphasis is placed on securing long-term, mutual relationships and change management. The implementation of an SCM system is likely to introduce a wide range of changes in and across member organizations and these changes are likely to be met with scepticism and resistance by individuals and organizations in the chain. Thus, the success of an SCM system cannot be guaranteed without effective change management. And we adopted the concept of information orientation (IO) as our method to measure the performance of an SCM system through information quality and information sharing. Therefore, this study examined the influence of mutual, reciprocal relationships among change management on information capability through information quality and information Sharing. The results of this study can be summarized as follows. First, change management had a significant influence on information quality, information Sharing and information capability. Second, information quality had a significant influence on information Sharing and information capability. Third, information sharing had a significant influence on information capability.

For the continuous information security governance, we have to focus on not just technical aspects like access control and DRM, but informal level management like information security(IS) behavior, culture, and personal value. But there are few informal level studies, while many formal level studies of IS governance or technical means. This study is an empirical test that how IS culture, normal beliefs, personal behavior and value affect employee's deviant behavior. And we define a lack of an awareness of value and importance on IS regulations in organizations as "Information Security Anomie" with the concept of anomie, a viewpoint on social organization.

Information behavior is an important area of research in library and information science (LIS) that has evolved over the last 75 years. The aim of this study is to investigate the recent trends of information behavior research by providing insights into emerging topical areas within information behavior. To conduct this study, the bibliographic data from Scopus was used, and the trends of information behavior were traced by using variations of key terms used in information behavior research, such as "information behavior", "information seeking behavior", and "information needs." In addition, the trends were analyzed in terms of content words in the title, highly cited journal articles, disciplinary categories, and author keywords. Information behavior research has its roots in LIS, but the findings of the study reveal that information behavior has expanded to other disciplines by intersecting a variety of topical areas. In particular, this study showed that information behavior in the health/medicine domain has become a predominant emerging topical area of research. In order to enhance our understanding of complex human behavior, future research should focus more on interdisciplinary aspects by measuring the scope of information behavior.

As the utilization value of personal information becomes higher, discussions about providing personal information are being conducted actively. One of the most common methods of providing personal information is that a group obtains a personal information with a consent of individual. However, the above method has 2 problems. First, more information is exposed than the information required by organization for utilization of personal information. Second, trusted party should provide organization with an authentication of personal information whenever they require personal information. To solve these problems, we propose a personal information management system with blockchain using zk-SNARK(zero-knowledge Succinct Non-interactive ARgument of Knowledge) for privacy. Our proposal enables individuals to guarantee reliability of their information and protect their privacy concurrently using zk-SNARK when they provid organization with their personal information. In addition, it is possible to manage the personal information data while ensuring the integrity of the data using blockchain and it is possible to share the personal information more conveniently than existing systems.

The National Science and Technology Knowledge Information Service (NTIS) provides information on national R&D projects. Project information consists of meta-information such as 'project name', 'project performance institution', 'research manager name', and text explaining projects such as 'research goal', 'research content', and 'expected effect'. There is a problem that it takes a lot of time to find the desired project information by checking all of the "research goals" or "research contents" in the list of results of searching for 1 million project information. To solve this problem, this paper proposes a project information summary system that summarizes the parts consisting of long texts within the national R&D project information. By analyzing the linguistic characteristics of the Korean language, a preprocessor was built and a project information summary model based on natural language processing technology was developed to process preprocessed text information. Through this, project information composed of long sentences is provided in a compressed and summarized form, which will help users to easily and quickly infer the overall content with the summary information alone.
