Instagram, a photo and image centered social networking service, has received increasing attention these days, from scholars and practitioners. However, little is known about the social and psychological factors that lead consumers to use this service. To provide a baseline understanding on Instagram users, the current study was conducted to discover perfectionistic self-presentation tendency expressed by the Instagram users and explore the relationships between identified perfectionistic self-presentation and intention to use Instagram variables with 250 participants. In addition, this study tried to determine the moderator effect of self-efficacy and self-construal. A comprehensive survey was directed and a total of 380 participants were recruited to verify anticipated hypotheses and research questions. The research results suggest that perfectionistic self-presentation has five sub factors: others conscious self-presentation, subjective self-presentation, environmental adaptation self-presentation, self-expansion self-presentation, and social self-presentation. The implications of this research findings are discussed.

차세대 웹 문서의 새로운 표준으로 자리 잡아 가고 있는 XML은 전자 상거래나 병원 관리 등과 같이 다양한 응용 분야에 적용되고 있다. 이러한 응용 분야는 XML 문서의 각 구성 요소 수준의 세밀한 액세스 제어를 요구한다. 따라서, 현재 XML 문서의 미세 접근 제어 기법에 대한 연구가 활발히 이루어지고 있다. 현재 제안된 XML 문서를 위한 미세 접근 제어 기법은 대부분 묵시적 권한 기법을 사용하여 상위 구성요소에 한번의 권한 부여로 하위노드에 권한을 부여하는 효과를 가지는 장점을 가지나, 각 구성 요소간의 권한을 체크하는 시간 오버헤드를 가지는 단점이 있다. 본 논문에서는 권한을 체크하는 시간을 감소시키기 위하여 XML 문서의 미세 접근 제어를 위한 명시적 권한 기법을 제안하고, 이를 이용하여 노드의 권한에 대한 모든 정보를 저장하고 있는 접근 권한 트리 모델을 제시하였다. 본 논문에서 제안한 접근 권한 트리 모델을 사용하면, 권한 정보를 저장하는 공간 오버헤드가 있지만, 권한 체크 시간을 감소시켜 사용자에게 보다 빠른 뷰를 제공할 수 있다.

Information on newspaper articles were categorized into different topics, and each categories within different topics were developed into a faceted taxonomies model which was combined with fundamental facets. After suggesting the plan to construct such a model, the research of actual faceted taxonomies were conducted. Faceted taxonomies divide information on news articles into different topics(such as politics, economies and others) and combine fundamental facets with categories(for example, politics can be sub-classified into general politics, administration, legal system, and others) and sub-categories. Each sub-categories can be further subdivided. In taxanomies, categories can have hierarchical relationships. Categories-Facets, for example, can be utilized to combine "arts" with "people", "action", "event", "time", "place" and others. And Sub-category of the classification of "arts" such as "art," "music," "dance" form hierarchical relationships with "arts" and, in turn, can be used for browsing and further inferences. Furthermore, combining category and facets results in hierarchical structure in order of fundamental facets. As for the pilot vocabulary construction, faceted taxonomies of 145 words from news paper articles on the topic of "arts" were constructed using all construction elements covered in this study.

In order to efficiently promote a nation's National Spatial Data Infrastructure (NSDI) vision, it is important that a rational NSDI promotion system should be established. For such a NSDI promotion system, cooperation among the related organizations and the consistency of policies are crucial. In these regards, the main purpose of this research is to suggest a desirable model for the NSDI promotion system. Also, this study attempts to demonstrate problems and provide solutions in Korea NSDI promotion system. To accomplish this purpose, the literature reviews and content analysis were used. Following are the major findings of this research. First, a desirable NSDI promotion system should be consisted of the upper system (at the planning level) and the lower system (at the executive or implementing level). Second, the upper and lower system in NSDI promotion system should both be vertically connected and be horizontally connected. Third, the upper system should consist of the NSDI promotion committee, civil advisory committee, and sub-committee. Fourth, the lower system for the execution purposes of NSDI projects should consist of the NSDI top manager, in each central/local government, and professional support institute.

This research emphasized that the importance of transformational leadership such as charisma, inspiration motivation, individual consideration, and intellectual stimulation. Moreover, it focused on verifying the effects of these four elements on green innovation through corporate environmental responsibility. In addition, the mediating role of CSR was clearly identified as a key variable that can lead to green innovation. To verify this, an empirical study was conducted on employees of companies in the Chinese service companies. Empirical studies have shown that all four elements of this trait are positively correlated with green innovation. CSR also has a positive impact on green innovation performance. CSR played a partial mediating role in the relationship between the four elements of transformational leadership and green innovation. Finally, based on this research, the useful meaning of human resource management is presented to Chinese entrepreneurs and employees, and the future research direction was discussed.

Current science education aims to guide students as future responsible citizens to make informed decisions on socioscientific issues (SSI). In the authors' previous study, it was found that conceptions of nature of technology (NOT) were explicitly represented in various contexts of SSI with differentiated levels of understanding, and cases of the informed NOT understanding included the key features of well-reasoned SSI decision-making. Therefore, enhancing NOT understanding could be one of the elements to leverage students' informed SSI decision-making. In this study, we developed a rubric to assess NOT understanding in the context of SSI and applied it to evaluate the impact of SSI instruction. Participants were 58 college students who took an SSI course for 6 weeks. Before and after the SSI course, they were asked to write decision-making essays on the Golden Rice issue (a type of genetically modified food). As a result of analyzing the pre- and post decision-making essay using the rubric, it was found that NOT understanding was improved after the SSI course; in addition, the salient patterns of NOT changes were analyzed in detail in order to gauge the influence of the SSI classes. Implications for science education were discussed.

Industrial heritage resources produced by industrial activities have historical and conservative values and value as cultural properties as they serve as a medium connecting the past, present, and future. In other words, Industrial heritage resources should be used, managed, and preserved simultaneously as important records and evidence for the future. Metadata is well known as a necessary and important factor for the use, management, and preservation of information resources. In particular, in order to describe various industrial heritage resources that have historical, cultural, and conservative values, metadata elements from various perspectives are needed to relate to the story, type etc. of data. Therefore, this study attempted to design metadata elements that can comprehensively describe different types of industrial heritage resources. And we designed metadata that suited for the purpose of using, managing, and preserving industrial heritage resources, through mapping and combination between industrial heritage-related metadata. As a result, metadata was grouped into five types(administrative, descriptive, preservation, technical, use) and prepared into a total of 25 higher & 86 lower elements.
