Recent interest in software education has naturally led to interest in computer science. Computer science is the study of theory and principle of computer and computational systems. This knowledge and concept of computer science is fundamental to software education. Recently, "Computer Science (CS) Unplugged", which is an educational method for introducing students to concepts of computer science without using a computer, has been widely used in classes around the world. CS Unplugged is a method for learning the basic principles of computer science through diverse playing activities. The problem, however, is that these CS unplugged activities take place in class without an analysis of how closely they relate to the core subjects learned in real computer science. Therefore, in this study, we will study on the comparison between the core contents of computer science and the core contents of computer science contained in the various activities of CS Unplugged.

Purpose : The purpose of this study is to analyze the history of nursing and medicine as phenomena of knowledge/power from the viewpoint of Foucault. Method : The present study adopts the genealogical method by Foucault, which tries to unite languages and knowledge. Foucault who attempted to show that the basic ideas which people normally take to be permanent truths about human nature and society change in the course of history. Results : It has been emphasized that the development of modern health care has been due to the progressive efforts of medicine and to medical discoveries. Foucault examines the institutionalization of knowledge and the power exerted thereby, with special reference to the devices of social regulation and their function over the madness, the disease, the crime, and the sexuality. The concept of power is that it is exerted spontaneously in verbal behaviors of individuals through knowledge of everyday life such as definition of body or mind. Therefore as to the problem of knowledge/power, this study tries to understand the meaning of history of nursing and medicine through an analysis of the formation of text of history. In order to have authority in a power relation, the medical professional asserts that medical discourse is the most scientific knowledge. Conclusion : According to the above findings, it can be concluded that the body is also directly invested in a political field: power relations have an immediate hold upon it; they invest it, mark it, train it, torture it, force it to carry out tasks, to perform ceremonies, to emit signs. Therefore the devaluation of nursing care is reinforced by the medicine which has the legitimate authority through use of the political skills about the body.

This study, which was begun in order to create a metal molding by using lines, a basic element of design, examined various characteristics and concept of line and the beauty of lines based on previous research on the subject. The result showed that formative interpretation of lines largely depends on intentional expression by using thickness and rhythm of lines. In order to obtain a metal molding that provides both visual freedom and beauty, rather than the conventional formative expression of lines, I used red copper plate and Phosphor bronze line for creating a pattern based on transformation and repetition of lines and an artwork based on the pattern. The result was not only a creation of a plane but the senses of three-dimension, speed, and unity in the overall shape. Further research will need to be conducted regarding formative interpretation of lines and emotional and intrinsic beauty through expression of lines.

A manufacturing industry has secured its competitiveness through cost reduction, research for new products, development of manufacturing technology traditionally. However, many manufacturers are being required of innovative efforts for business sustainability by emergence of new technology and industry owing to fast technology development and convergence among technologies and industries. Continuous growth can not be expected with the way of simple manufacturing and sales under the 4^th industrial revolution era. Separation of service from product is getting more vague in some specific area and a service provider is often offering its own product together. Innovation destroying manufacturing value chain with servitization can only create the new value. Basic concept of servitization, paradigm change and future prospect of manufacturing industries suffering from the 4^th industrial revolution will be analyzed in this paper. Also, the strategy, application and methodology for servitization required in the convergence period will be researched.

To determine efficient methods of database teaching, this paper applied the situated learning theory to the teaching and learning method and analyzed the effects. Previous related studies were also examined, with the essential contents in database analyzed based on Bloom's taxonomy of educational objectives. Moreover, this paper presented a strategy wherein the contents of database learning are classified into two categories: basic knowledge and technical and extended knowledge. Experimental and control groups were selected based on related studies, and the effects of database teaching and learning method, determined by technique and attitude area as well as knowledge area. After preparing and applying to the teaching and learning method the actual educational curriculum, the following results were drawn: (1) the experimental group showed better performance in terms of understanding the concept of database, operating database, and constructing a database table when the situated learning theory was applied to the teaching method, and; (2) the experimental group was also more receptive compared to the control group, which opted to take technique-oriented database courses. Therefore, various teaching and learning methods aside from the situated learning theory should be applied and analyzed in database and computer science fields for maximum effects.

The purpose of this study is to identify the difficulties of learners who started programming after entering college and to search an effective software education method as university liber arts for non-science major students. In order to do this, we analyzed the difficulties of learners in Python programming classes composed of students from various majors at H University through questioning and taught them using flipped class model with pre-questions. The questions that students submit are collected online before class every time, the data on the degree of the difficulty of feeling and the understanding of feeling were obtained through the questionnaire. As a result, for learners who are new to programming, the learners should allocate the process of making the problem into a logical abstraction at the beginning of the curriculum before learning the basic concept of computer language, each lesson should be practiced through the bottom-up problems enough to provide a logical understanding before actual coding. In addition, detailed curriculum should be developed according to characteristics of learner's major, contents and conducting level.

In this study, the students' responses on the chemistry items of in the general science of College Scholastics Ability Test (CSAT) implemented for the past 3 years since 1999 were investigated. The number of items by content and inquiry process, the average percent correct by content and inquiry process, the distribution of items by the level of percent correct, and the items with high and/or low percent correct were analysed. There were the fewest items in 'environment' area, especially in 'ozon layer', no test item had been made. The most difficult content area was 'acid rain' in 'environment'. By inquiry process, the most number of items belonged to 'analyzing & interpreting data', and 'identifying problems & formulating hypothesis' was the most difficult process. No test item came under the level of 'very difficult', and many items under the 'easy' or 'very easy' level. Students were generally poor at solving test items demanding several concepts, and very good at simply requiring basic concept treated in lower grade. Educational implications are discussed.
