This study focused on the design and development of contents using Unplugged CS method to learn computer science knowledge. With the strengthening of software education, all universities students including elementary and junior high school students are demanding knowledge of computer science centered on the computational thinking. We have developed educational contents using unplugged computing method as a way to effectively learn the concept of computer science. First, we analyze the related research of Unplugged CS theory and investigate the educational method accordingly. And we divided the areas of computer science and selected learning concepts in each area. The contents of learning were divided into basic and intermediate classes considering the level of the learner. The subject of learning contents was selected evenly in the area of computer science and it consisted of 16 basic subjects and 16 intermediate subjects based on concepts that are important in each field. In order to confirm the validity of the Unplugged CS learning topic and the development contents for computer science, we conducted expert reviews and content validity tests. As a result of the validity test, the validity of the learning topic and area selection was found to be more than .92 for the CVI value and the validity of the 32 subject learning contents was over .935 in basic level and .925 in intermediate level for the CVI values. Based on the design contents, we developed digital contents for online learning and put them in the system. We expect that this study will contribute to the understanding of computer science for all, including elementary and junior-high school students as well as students at software - oriented universities, and contribute to the spread of software education.

This study focuses on the legal concept of virtual money, focusing on the case of how we can change the framework of fixed thinking about our trade concept and money with the fourth industrial revolution. The legal character of the virtual money, which played a role as a means of trading in crime, could be discussed, and the court could put it in the category of " property " as a subject of confiscation. Many people are expressing empathy for the fact that there will be many traits in the future world that are difficult to predict. At this side, when the legal validity of the advantage is not recognized as the legal money yet to be recognized as the legal currency, it begins to be discussed as a necessary means of trading between individuals, businesses and individuals. Defining a legal character can be very significant in determining policy direction related to future operations of virtual money. But to date, it is very difficult to establish the legal character of virtual money through existing legislation. Therefore, as we looked at in this case, we examined whether the property was subject to the seizure of the profits from the crime. Attention was also given to the possibility of such abuse of virtual money and whether effective legal interpretation was possible for the categories of assets subject to seizure.

E-commerce and business information systems are being introduced in most of enterprises with the development of internet recently. Meanwhile the introduction of enterprise portal concepts and the enterprise informatization provide a necessary premise for insuring a competitive power. Therefore, it became necessary to research on the project of reusing the data of e-commerce. In this paper, we make a domestic maker the subject and implement a XML based electronic catalog(e-catalog) system for electronic commerce(e-commerce) based on web. The implemented XML based e-catalog system can reduce time and expenses needed for making, keeping and distribution in paper catalog systems. It also can correct the data reuse problems in the e-catalog systems implemented by HTML. Exchanging and reusing data used in e-commerce is essential to the integration between business information systems and points to the enterprise portal.

In terms of development for CMC computer science curriculum was started from 2006 year, and it was confirmed at 2013 year and adapting through 1 to 8 grade. CMC is focused on the "Develop computer fluency, not just computer literacy", "Develop thinking process skills, not just content mastery", and "Highlight the interconnectedness of knowledge, not just address a topic/subject in isolation" as a base of the curriculum. CMC have selected core factors which are Thinking process skills, Computer literacy integrated with fundamental concepts and thinking skills, Thematic integration, Spiral curriculum, and Scalability. Once CMC have been developed as a common computer curriculum by India government, both of computer training course and textbook development were conducted by government. In addition, they are trying to enforce the computer education. It suggests to Korea some significant points which were the necessity of Computer education as an independent subject and the requirement of Software education and Computational thinking as an educational content.

Recently, shape analysis of human organs has achieved much attention, owing to its potential to localize structural abnormalities. For a group-wise shape analysis, it is important to accurately restore the shape of a target structure in each subject and to build the inter-subject shape correspondences. To accomplish this, we propose a shape modeling method based on the Laplacian deformation framework. We deform a template model of a target structure in the segmented images while restoring subject-specific shape features by using Laplacian surface representation. In order to build the inter-subject shape correspondences, we implemented the progressive weighting scheme for adaptively controlling the rigidity parameter of the deformable model. This weighting scheme helps to preserve the relative distance between each point in the template model as much as possible during model deformation. This area-preserving deformation allows each point of the template model to be located at an anatomically consistent position in the target structure. Another advantage of our method is its application to human organs of non-spherical topology. We present the experiments for evaluating the robustness of shape modeling against large variations in shape and size with the synthetic sets of the second cervical vertebrae (C2), which has a complex shape with holes.

In this study, A DDC online system was developed which provides subject access and browsing function for class numbers or subject terms. A knowledgebase of the DDC Schedules and Relative Index was designed for this purpose using IBM-PC. From the DDC 20th edition, subjects from 004 to 006, covering‘data processing’,‘computer science’‘programming and progrms’, and etc., were selected for this experiment. DDC schedules are represented as a frame structure which is apt to describe hierachical structures. This experiment, joining the DDC to the information retrieval environment of an online catalog, will contribute to the future of the online DDC system by providing possiblities for search strategies not feasible through the alphabetical approach of subject headings and keywords presently supported by online catalogs.
