  • Indexes, especially subject indexes, are major tools for information retrieval. To enhance the retrieval effectiveness of subject indexes, the semantic and syntactic relationships of indexing languages are very important elements. This paper examines the afore-mentioned relationships, based on purely the syntax and semantics of Korean language. The outlines of this study are as follows: 1. The characteristics and usages of controlled vocabularies, particularly subject headings lists and thesaury, are reviewed. 2. The semantic relationships, such as equivalence, hierarchical and associative relationships, are defined, and their categories are investigated in detail. Accordingly, the usages of 'See' and 'See also' references are suggested circumstantially. 3. The syntactic relationships are also examined. Particularly, for the syntactic relationships of multiword indexing terms, two kinds of subject entry formats are compared. Since it is more rational for subject headings organized by the principle of context-dependency, the two-fine entry format is recommended for subject indexes. 4. Computerized production techniques of 'See' and 'See also' reference for the semantic relationships of indexing terms are presented. 5. Computerized production techniques of subject indexes representing the syntactic relationships of indexing terms are also presented.

  • The purpose of this study was to research elementary school on safety education in the subject of practical arts. The subject of practical arts of an elementary school have positive attitude about safety education and must prevent an accident to be able to happen during a class of a practical course previously. Safety education has further an interest on subject of practical arts of practice and must induce an aggressive interest of teachers in order to be able to prevent an accident previously. As the above results, to raise the perceptions of elementary school teachers on safety education in the subject of practical arts, it is necessary to search for ways to induce teachers' active interest in safety education and help them experience safety education in the subject of practical arts at teacher training centers.

  • On the border between the Geography subject and the Science subject, much of the content area is found to be interrelated or shared in common due to the characteristics of each subject. This possibly causes a problem of which of the two subjects should treat these overlapping areas with more responsibility and importance, and, as a result, might cause teachers to neglect the areas and result in insufficient treatment of the areas on both sides. In other words, these overlapping area can be overlooked on both subjects. On the other hand, as the science subject treats these areas more deeply and widely in both quantity and quality, the geography subject might lose its original content area to the science subject and accordingly lose its characteristics as an independent subject. To conclude, the following suggestions must be taken into consideration when we develop and organize the environment-related unit in the geography subject. First, the various real cases damaged by pollution, the efforts and steps to avoid being polluted, the inquiry questions and activities to set up the value of the environment conservation, and sufficient assistant materials such as maps, graphs, photos, illustrations, statistics, which will help to realize the environment problem more directly and clearly, must be presented in the textbooks. Second, as the environment education is not just teaching the environmental pollution, the content should be composed for the students to realize the value of the environment and to change their awareness and attitude toward the environment. Third, the environment education cannot be restricted to a certain subject, or it needs to be approached in multi-subject areas. To exercise a effective environment education while we maintain the unique characteristics of the geography subject, a way to link the environment and the region, which is one of the main concepts of geography, should be developed. Finally, textbooks are indispensible materials to teaching-learning, but for more effective teaching the teachers of geography should try to recompose and reorganize the content and to develop newer and more effective teaching material-aids.

  • The purpose of this study is to analyze the currently operating subject guides in academic libraries and to suggest measures for improvements of them. To do this, 22 out of 151 academic libraries which have more than 1,000 enrolled college students in the university and two institutes of science and technology were selected and the libraries were analyzed according to 12 criteria. The main results of the data analysis were as follows: First, the subject guides did not clearly indicate which service tool to use. Second, there was a difference in the subject guide format in the same academic library. Third, libraries tried to provide a lot of information sources on the subject guides without considering users' needs. By offering many kinds of information sources, students had to choose the information sources they needed. Improvement plans are: First, it is necessary to develop the subject guide of the college courses. Second, Content-based subject guides are necessary through standardized format. Third, it is necessary to unify the name of menu of information resource. Fourth, the number of information sources included in the subject guides should be minimized. Fifth, it is necessary to establish a cooperation system between academic libraries to develop the subject guides.

  • Although university libraries run by the subject-oriented serviec systems are increasing more and more, many problems are emerging as a result of tying out the subject classification of the sources without an enough advance knowledge, consideration of reality, and the study about effective management of subject-oriented sum system. Through the research of 37 university libraries run by the system of subject-oriented service, it was proved that for the effective subject-oriented service system, the reasonable classification of the subjects, considering the form and structure of the building, the number of users on each subject and the organization of the collection, and the subject librarians, who would take charge of subject-oriented service systems are indispensable. Therefore, the subject-oriented service system to be rooted strongly, the role model of the subject-oriented service system adequate to the reality of Korean university libraries should be developed, and the efforts of the people on the spot such as acquiring enough supports and training of the subject librarians should be arranged.

  • This study investigated the utilization and interrelatedness of Scopus subject categories. To conduct this study, major and minor subject categories of journals listed in the 2017 Scopus index were used. The results showed varying degrees of interrelatedness of subject categories. At the major subject category level, the utilization was the highest in Medicine, while Social Sciences showed a greater degree of interrelatedness in comparison to Medicine. Yet, at the minor subject level, 2700 General Medicine was particularly dominant in terms of utilization and interrelatedness. Moreover, co-occurrences of minor subject categories showed varying degrees of interrelatedness between pairs of minor subject categories. Pairs of minor subject categories showed the following characteristics: a) two subject categories having identical or closely identical descriptions, b) two different categories having an interrelationship by subject areas, and c) one category conceptually encompassing another category. Due to varying degrees of utilization and interrelatedness among subject categories, minor subject categories that may greatly influence the major subject categories in conducting research studies should be investigated in detail.

  • During the last three decades, earth science has been re-conceptualized as an interdisciplinary discipline entitled Earth System Science (ESS), which is based on knowledge of the physical earth system and human impact on the earth. While there is increasing effort to teach earth as a system in K-12 education, teachers' preparedness of to teach earth system is still in its infancy. This article focuses on reviewing the literature of teachers' knowledge of earth systems and of how teachers' knowledge of subject matter affects their teaching practice and pedagogical content knowledge (PCK). First, the study investigated a literature of PCK in general as well as in science teaching. Then this study duscuss what teachers' subject matter knowledge (SMK) is and what it means to be in teaching earth system science. Third, a literature of teachers' knowledge of earth system was reviewed. Finally, a number of suggestions and implications are made as to what teacher education program should do to better prepare future teachers to teach earth systems.

  • Librarians, who work for University libraries in Korea experience a lot of confusion and difficulties because of rapidly-changing technological conditions and under-developed understanding of the University Libraries' full potential on the part of the users. I present the concept of 'Subject Services' as an approach which librarians could use to overcome these difficulties in their own way. The 'Subject Services' refers to the 'subjectized' collection development and reference services, which can more specifically address the users' needs. To make this idea more concrete, I selected Pusan National University Library as the case of my qualitative research. And I made use of various research techniques such as 'participant observation' and 'ethnographic interview'. After looking into the case library in depth, I found that the concept of 'Subject Specialist'. a person who has double master's degrees including that of library and information science, is more suitable to the University Libraries in Korea at the present developmental stage. At the end of this article, propose that the development of Core Collections, the improvement of subject-oriented reference services and the continuing education of librarians should be emphasized.

  • In this paper, we propose a Science subject program based on programming learning to improve computational thinking ability in middle school. As the necessity of software education rises recently, the subject of information was designated as the mandatory subject in elementary, middle and high schools. In order to cultivate the ability that enables the leaners to search the knowledge in need by themselves and raise troubleshooting method, not the existing indoctrination, his thesis was willing to improve Computational Thinking ability and improve the ability of considering and thinking the matters by using scratch language. For that, this thesis developed and suggested science subject program that utilizes the programming learning.
