This study aimed to compare academic passion for science pedagogical content knowledge (PCK) between pre-service and in-service elementary teachers. In addition, a comparison between passion for science subject matter knowledge and passion for science pedagogical knowledge was made for each group of teachers. Participants comprised 182 students from colleges of education and 161 in-service teachers. We analyzed between- and within-subject comparisons for each component of academic passion for science PCK. The results of this study are as follows: First, between-subject comparison demonstrated that, in academic passion for science subject matter knowledge, in-service teachers had a higher passion for "liking" and "importance" than pre-service teachers, whereas pre-service teachers had a higher passion for "time/energy investment" than in-service teachers. In academic passion for science pedagogical knowledge, pre-service teachers had a higher passion for "time/energy investment" than in-service teachers. Second, the within-subject comparison showed that only "harmonious passion" was higher for science pedagogical knowledge than science subject matter knowledge in pre-service teachers. However, "liking", "importance", "time/energy investment", and "obsessive passion" were higher for science subject matter knowledge than science pedagogical knowledge in in-service teachers. The educational implications are discussed.

The core of subject matter education is determined by the choice of subject matter taught to students and by the organization of content according to educational objectives. The purpose of this research is to suggest ways to improve the present content of science education so as to prepare students and schools for a radically different future. We deduced the main issues the solution of which could lead to significant improvements in the contents of science education by analyzing previous studies and investigating the changes in content that were effected during curriculum revisions in the past. The main issues thus revealed through this study are as follows: the essence of the contents of subject matters in science education, the social and cultural background of change in the science curriculum, the rational steps on the way to choosing contents as part of the science curriculum, the processes of choosing the main contents of each subject, the international comparative study of contents, the updating of contents for the benefit of future society, and the reorganization of subject contents. In order to find a concrete improvement on the issues deduced, we organized an expert group. Then, we proceeded to collect and analyze the experts' opinions. A survey was administered to 19 science education experts working with universities and colleges of education. We examined their degree of agreement on the issues and problems, and on the steps that may be taken to us the improvements on these issues. we suggested that: collecting opinion and reaching an agreement on the essence of the contents of the subject matters in science education, the necessity to choose core contents within the scientific domain, developing a structure map in order to integrate and connect various subject domains, presenting explicitly the objective of inquiry by grades, moving toward integrating science contents, diversifying the construction of science textbooks.

Subject classification of journals is important because it can be utilized for the improvement of scholarly information services and analysis by research area. The classification by experts in a subject area wastes a lot of time and expense. On the other hand, the simple classification with basic information, such as the journal title has limitations. To solve this problem, this paper suggests the automatic classification of Korean journals using the SCI journals information cited by Korean journals, and an analysis of the classification result. In particular, this study adopted the WoS subject categories for classification to support the base for comparison between the Korean citation database and the global citation database (KSCI vs. SCI).

It is a common practice in many research areas that multiple range tests for a between subject factor such as Tukey are applied to a within subject factor in a repeated measures design. Tukey procedure, however, sometimes detects no pairs with different means even when the hypothesis of all equal level means is rejected. This study attempts to provide a rationale for the proposition that Tukey is inappropriate post hoc procedure for a within subject factor in which the observations are correlated. We introduce two multiple range tests, Bonferroni and Scheffe, for a within subject factor and show that Bonferroni is more appropriate than Scheffe for pairwise multiple comparisons. Subsequent simulation study indicates that Tukey has significantly less power than Bonferroni in detecting actual difference between means of some pairs when the observations of a within subject factor are highly correlated.

This study suggested the necessity of subject access for understanding on the contents of children's books which library would select children's books efficiently. Especially it was presented examples of efficiency on subject access analyzing Korean translation fiction of Newbery Medal Winner's books. Besides subject on the contents of books, it suggested fiction genre and gender and age of protagonist as elements which should be taken into account in process of Subject Headings development.

This study investigated the level of academic passion for elementary school teachers' science pedagogical content knowledge (PCK) and examined the factors that influence the passion. To this end, 161 elementary school teachers in Seoul were selected, and academic passion tests were then administered to evaluate their academic passion for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participating teachers. The results revealed that 'importance' and 'harmonious passion' for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. However, 'time/energy investment' and 'obsessive passion' for learning the knowledge were slightly higher or lower than normal. The 'like' for learning science subject matter knowledge was relatively high, but the 'like' for learning science pedagogical knowledge was slightly higher than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to advanced major at undergraduate than teaching career. The teachers evenly selected some factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. These identified characteristics included 'individual interest', 'high school track', 'experience in advanced major at undergraduate', 'experience in science-related graduate school', 'experience teaching science in elementary school', 'experience teaching science at the gifted education institute', 'experience in charge of science subject teacher', 'experience in science-related teacher training', 'experience in developing science-related teaching and learning materials', 'experience in charge of science or science-gifted related work', and 'experience in a science-related teacher community'. However, a slight difference was noted in the selection ratio depending on advanced major at undergraduate. Based on these results, the practical implications for improving their academic passion for science PCK are suggested.

In this study, an investigation has been made on the status of the issuance of librarian qualification, the status of operating Subject specialized librarians at home and abroad, the status of professional manpower of the similar cultural facilities, and their recruitment method, based on which an attempt has been made to propose a way to nurture the Subject specialized librarians. First, I propose a method for training Subject specialized librarians through a regular curriculum and a retraining process, while suggest the ways to nurture the Subject specialized librarians from undergraduate and also nurture the existing librarians to become the Subject specialized librarians. Second, the basic qualification of the Subject specialized librarians must have a career of more than 3 years in a specific subject area with a master's degree or higher, and in order to have a subject area background, it is proposed that a bachelor's degree or a master's degree must absolutely be acquired in the corresponding subject area. Third, in order to improve the treatment of such Subject specialized librarians, the Subject specialized librarians in the administrative service group could be organized into a research librarian (or library and information science) series and types as a subordinate literary series under the researcher position. That is, it is proposed to differentiate the librarians and the Subject specialized librarians by reorganizing series and types of the Subject specialized librarians while maintaining the current librarian series.

The purpose of this paper is to investigate search efficiency of controlled vocabulary versus uncontrolled vocabulary subject access in online catalog systems. The question of the effectiveness of controlled versus uncontrolled vocabulary in information retrieval has been raised in many literatures. A debate continues in the Library and Information Science Professions over the relative merit, appropriateness, and efficiency of uncontrolled vocabulary subject access in online catalog systems. Actually users used to combine uncontrolled vocabulary subject searching with controlled vocabulary subject searching. But the success of user's subject search depends on his choice of search terms. Also the technical developments that facilitate cooperation among information services in general make it increasingly possible for such cooperation to take place on an international level. In this study, several common types of vocabularies on online catalog systems are described and compared, especially usages of vocabularies in multilingual environment are analyzed.
