This study aims at defining the concept of OPAC, tracing of research trends and development of it, and clarifying various methods of subject access and patterns of bibliographic searching in OPAC as well as strategies for improving to implement online catalogs. Although OPAC is so far the most user-friendly bibliographic searching method, there are still a lot of issues including online subject access in particular. Therefore a more effective and useful method for computer end-users have to be developed, for instance, improvement of an indexing system, a n.0, pplication of the classification system as a searching tool, a new design and construction of standardized thesaurus, betterment of user interface, introducing of expert system into bibliographic searching, establishment of subject authority file. Those would raise the success-rate of users seeking bibliographic information in the library catalogs. Korean libraries are in very early stage of OPAC implementation so that every efforts and concerns to improve strategies and techniques for subject access to OPAC have been strongly asked.

The PCK of teachers about informatics subject, which is viewed as one of required subjects in today's information society, is linked to what and how to teach, and that is very significant in terms of academic education. However, there are currently no efforts to develop items geared toward evaluating the PCK of teachers about informatics subject or to make a factor analysis of those items, though the importance of that subject in information society has been discussed. The purpose of this study was to develop and validate an instrument to size up the PCK of preservice elementary teachers about informatics subject. The finalized instrument consisted of 39 items regarding five factors that involved knowledge of curriculum, knowledge of expression, knowledge of content, knowledge of evaluation and knowledge of teaching methods.

This paper have been knowing about policy background about Computer Science Education in UK. Every schools in UK have been teaching Computing as a subject matter from september, 2014. Department of Education in UK had replacement ICT to Computing subject. The institute have accepted that problems about ICT subject which school teacher recognised and the needs of academic sector, and the entrepreneur's needs for talented person of 21st century. We have known that Computing at School(CAS) had started grass root organization, which had been trying to changing the computer science curriculum. In the processes, it was corporation very closely among organizations, such as government, universities, entrepreneurs, awarding bodies for evaluation, and non-profit initiatives. Through this research, we have get some lessons for advancing of software education in South Korea.

The purpose of this study is to explore the content hierarchy of ICT curriculum in elementary school. Korea Ministry of Education has been released the 2nd ICT curriculum by last year. Over the past few years, several studies have been focused on the problem of 1st curriculum. But there has been no study that tried to find the internal justification of computer subject matter. Also there has been different hierarchy each and every textbook. And, we explored a standards of selection and a principles of organization of computer subject matter. then applied it to the content hierarchy of 2nd ICT curriculum. We tried to find relations with the content hierarchy and the types of thinking learner use. We suggests that computer subject can be organized by hierarchy of content and learners experiences. It can be logically organized between different grade, horizontally organized between same grade.

Due to the development of the e-commerce, the shopping mall such as auction collects and manages the personal information of the customers for efficient service. However, because of the leakage of the Personal information in auction, the image of the companies as well as the information subjects is damaged. Even though the organizations and the companies store the personal information as common sentences and protect using role based access control technique, the personal information can be leaked easily in case of getting the authority of the database administrator. And also the role based access control technique is not appropriate for protecting the sensitive information of the information subject. In this paper, we encrypted the sensitive information assigned by the information subject and then stored them into the database. We propose the personal policy based access control technique which controls the access to the information strictly according to the personal policy of the information subject. Through the proposed method we complemented the problems that the role based access control has and also we constructed the database safe from the database administrator. Finally, we get the control authority about the information of the information subject.

In this paper, we propose the computational thinking education framework which provides three steps of computational thinking process and three kind of activities about computational thinking learning in class. The key idea of this framework is to provide the guidelines of designing activity steps of teaching and learning computational thinking in class using three axles of framework such as problem area, process of learning, and steps of computational thinking process. After designing a framework, we show that sample course of programming education program containing contents of Informatics subject in middle school by implementing our framework. Proposed framework and programming education program in middle school will be the good case study and guide to implement computational thinking concerned education programs in elementary, secondary, and universities.

This study is about the direction of how to compose the information domain curriculum in the domestic subject matter centered curriculum system. To this end, subject-centered and competency-centered curriculum were compared and analyzed, and how the information domain was organized in two types was suggested. In spite of emphasizing competency, the domestic curriculum was judged to be inclined to the subject-centered curriculum because it emphasized the presentation of national-level educational goals, a subject learning model, and textbooks. As examples of the information domain subject-centered curriculum, the information domain of the elementary practical subject and the middle school information curriculum were presented, and the SW convergence curriculum was presented as an example of a progressive curriculum. Under such circumstances, it was emphasized that in order for the learner to lead a life in an intelligent society in the future through the information domain including SWAI content, it must be explicitly described in a subject-centered perspective with computer science as the parent study.
