  • The Purpose of this paper is to suggest directions for the future education of Library management. For this purpose, some theoretical backgrounds are traced based on the historical events, the standards provided by international and national organizations, and theories suggested through researches. And the percentages of library management subjects in the curricula of ten Library and Information Science Departments are calculated divided by compulsory and elective ones, along with the contents analyses of a few textbooks in the field. The hypotheses to be tested are as follows: 1. The American postgraduate library education was introduced into Korea as an undergraduate course. So the importance of the subject of library management was recognized as in America, and the numbers of subject Would have been increased, and the contents detailed. 2. The contents of the subject taught would not have changed much since its introduction. It means that they will be almost the same as those were prevalent in the United States of America in the 1950s, when the American education was brought into Korea. The hypotheses can be accepted as being true. Based on the conclusions, some suggestions, including the teaching of the subject should be directed more towards management aspects rather than administrative ones, are provided.

  • This study experimented with automatic classification of subject headings using BERT-based transfer learning model, and analyzed its performance. This study analyzed the classification performance according to the main class of KDC classification and the category type of subject headings. Six datasets were constructed from Korean national bibliographies based on the frequency of the assignments of subject headings, and titles were used as classification features. As a result, classification performance showed values of 0.6059 and 0.5626 on the micro F1 and macro F1 score, respectively, in the dataset (1,539,076 records) containing 3,506 subject headings. In addition, classification performance by the main class of KDC classification showed good performance in the class General works, Natural science, Technology and Language, and low performance in Religion and Arts. As for the performance by the category type of the subject headings, the categories of plant, legal name and product name showed high performance, whereas national treasure/treasure category showed low performance. In a large dataset, the ratio of subject headings that cannot be assigned increases, resulting in a decrease in final performance, and improvement is needed to increase classification performance for low-frequency subject headings.

  • Recently, the interdisciplinary linkage between engineering and social science has received an increasing attention as an emerging education discipline. Due to intrinsic complexity of innovation process and heterogeneity of disciplinary nature, however there exists little, if not no, effort to draw a common framework in terms of educational scope and contents of the new subject. This paper presents a number of criteria and guidelines for building up new educational framework by integrating engineering subject and social science subject. Specifically, three neo-disciplines, technology policy, technology management, and economics of technology are considered since it is postulated that the forementioned disciplines have established academic identity and fundamental structure By nature, this paper is an exploratory and seminal one. It is not the purpose of this paper to provide a concrete table of contents of educational material. Instead, it merely brings up a discussion topic for the wide audience of academic arena, leaving the gradual consensus and convergence as future task.

  • A new device introducing brief pulses of odorozed air synchronized with subject's respiration to human subjects creating a positive response was developed. By the using superimposition technique of an evoked potential the positive responses to skatole in normal subject's were distinguishable. The odorant pulse trigger was the subject's respiration. Responses to aerosolized skatole consisted mainly of a positive wave with a peak latency of approximately 150 ms. In our cases, saturation of responses was found after 4-5 averagings with the responses becoming most clear after 7-8 averagings. And in cases of Alzheimer disease very quick adaptation was recognized.

  • The purpose and content of Chonnam National University Center for Science Talented Education program and students' responses were described. The program was developed with the purpose of providing various learning opportunities for science talented students according to the level of their learning abilities. Students are given a variety of activities based on their potentials and interest. The program was developed in four subjects, such as mathematics, information science, science Ⅰ (physics and earth science), and science Ⅱ (biology and chemistry). Each subject consisted of simple inquiry, advanced one, and project, even though it had its own distinctions. Students were selected for each subject based on two criteria, that is, achievements in school science or mathematics (the upper 3 percent of the 8th grade students) and examination scores. Means and standard deviations for each subject were as follows: 51.8 and 13.3 for Science Ⅰ, 53.1 and 13.9 for Science Ⅱ, 36.7 and 10.7 for mathematics and 36.4 and 12.5 for information science. Thirty hours of summer classes were performed, and a survey was administered to obtain students' responses concerning difficulty, interest, teaching and content of the program. They gave relatively favourable responses in most area, but lack of time for studying was revealed in mathematics and information science. Further study in needed to get detailed and more accurate results of our program.

  • This study explored ways to implement a competencies-based curriculum in schools by reviewing exemplary cases that have introduced Key Competencies (KCs) in the school science curriculum. Since the OECD redefined key competencies as 'what people should know and do in order to lead a successful life in a well-functioning society', many countries have emphasized the use of a competencies-based curriculum. Foreign and domestic classroom cases, which have used a competencies-based curriculum in science teaching, were collected and analyzed. Through open-ended interviews with teachers and principals, we investigated changes of teachers' professional knowledge and practice that were evident as a result of the implementation of competencies-based curriculum in science class. Foreign science teachers suggested ways to relate competencies-based curriculum and science curriculum including maintaining a balance between competencies-based curriculum and content-based curriculum. They also integrated KCs into all subject-based curriculums, gave priority to KCs over subject matter knowledge, and developed KCs through teaching science contents that students wanted to learn. On the other hand, Korean science teachers suggested reconstructing competencies-based curriculum by extracting common attributes from the existing subject areas. They also made KCs realized through content teaching, and developed various KCs within science contexts. Implications of the competencies-based curriculum for science teaching and learning were discussed at the end.

  • Despite the rapidly growing body of research on science teachers' pedagogical content knowledge (PCK), most of the research has mainly focused on the definition of PCK and its components. The main purpose of this research was to explore the operational definition of PCK and to suggest another form by re-conceptualizing PCK, with the newly defined and conceptualized PCK capable of being used as standards and/or criteria in selecting the curricular content of and deciding the subject area of science teacher education. In this research, the science teachers' PCK was defined as the "practical knowledge and skills that are acquired through the curriculum of science education and in the course of teaching experiences, and which are used in their teaching of secondary school science." The science teachers' PCK was further defined as consisting of two integrated and/or combined dimensions: subject matter and pedagogy, each of which comprises several components. In this paper, the PCK is called science education literacy. The paper also presents the ways to apply the operational definition of PCK and re-conceptualized PCK and a few suggestions for the research on science teachers' PCK.
