This study aims to understand science education conducted in North Korea by analyzing the PCK components shown in two science teacher's guidebooks: (1) Guidebook for 1^st grade elementary school and (2) Guidebook for 1^st grade middle school. These were published after 2013, when "the first 12-year Universal Compulsory Curriculum" was implemented in North Korea. The analysis shows that both elementary and middle school guidebooks had the highest percentage of content in "Knowledge of Subject Matter", followed by "Knowledge of Instructional Strategies in Science" and "Knowledge of Science Curriculum". On the other hand, "Knowledge of Assessment in Science" and "Knowledge of Students" were significantly low in content. Within the "Knowledge of Subject Matter", both elementary and middle schools had the highest proportion of content in "Concepts and Theories", along with "Experiments and Inquiries" that was also significantly higher than other PCK components. Science teacher's guidebooks in North Korea advocates constructivist teaching style by using "discussions" as the main activity when conveying scientific concepts and theories to students or conducting scientific inquiry classes. Furthermore, "Knowledge of Instructional Strategies in Science" was mainly focused on guiding the "Instruction sequence and method" from the "Topic-specific Strategies", while only a small part of the "Subject-specific Strategies" was being presented. Also, Science teacher's guide books in North Korea included only a few theoretical elements of science education in both the general outline and the particular sections of guidebooks. "Knowledge of Science Curriculum" was mainly composed of "Lesson Objectives" with some inclusion of "Vertical Articulation" and "Horizontal Articulation". "Knowledge of Assessment in Science" and "Knowledge of Students" accounted for a small portion compared to the science teacher's guidebooks in South Korea.

In this study, a science writing heuristic class with emphasis on social interaction and tool improvement for 10 middle school students at the National University Science-Gifted Education Center in Jeollanamdo was conducted to investigate the perception of STS (science technology society) relationship and students' perception of the effects of class. After science writing heuristic class emphasizing social interaction and tool improvement, the students became aware of the STS relationships as follows: Science-gifted students have come to perceive that experimental tools and technology contribute to the development of scientific theory, that it is difficult to solve all social problems with only science and technology, and that science is a social interaction activity. In addition, science-gifted students responded that they became aware of the relevance of STS through intensive inquiry conducted on the same subject for several hours, communications with colleagues in another group through peer reviews, communication to solve problems with colleagues in the same group, activities to improve tools in the process of inquiry, inquiry using familiar materials and phenomena. In order for students to effectively recognize the relationship of STS in science-gifted class for middle school students, it is necessary to provide experience to solve problems using various experimental tools, experience to have trial and error in the process of solving inquiry problem under the same subject, experience to improve tools in the process of solving inquiry problem, experience to communicate with colleagues who conduct inquiry activities under the same subject, experience to share the results with other groups, and inquiry activities using familiar materials and phenomena.

The purpose of this study was to explore the direction of application and quality management plan of science curriculum of elementary and middle school according to the 2009 revised curriculum. In order to do this, nationwide survey was administered. The subject was 126 elementary school teachers and 88 middle school science teachers. It was founded that teachers had negative opinion on the introduction of the grade cluster system. They considered that it was appropriate to link the contents of Science subject with Practical Arts(Technology Home Economics) subject by similar topic. Science classes were implemented without changing the number of class hours in most schools. They recognized the necessity of differentiated instruction in science classes, but they seldom applied the differentiated instruction. And they suggested that the teaching-learning materials, evaluation materials and contents be provided to apply the STEAM. This study designates the following strategic supports for the effective implementation of 2009 revised science curriculum; 1) the science teachers training program to provide useful information for understanding and teaching the 2009 revised science curriculum, 2) the teachers' community in the school, 3) the development and provision of the feasible STEAM plans.

The opinion, that the history of science should be introduced to science lesson, has been continuously emphasized by a group of people who supported the needs of science and scientific process, nature of science, and the interaction between science and society. When the importance of the integrated science education is emphasized, the history of science is suggested as an effective curriculum for it. To respond to this identified interest, we developed a lesson of the history of science by selecting the contents of the history of science as subject topics of the integrated science and by utilizing the findings of previous studies related to the history of science in science educations. To develop the history of science class as a subject of integrated science, we chose 'the age of the earth' as a unit. After the pilot test of the unit in secondary school students, the possibility of offering the lesson as a regular course was examined with analysis of the students' reactions showing its effectiveness.

This study is to develop an operating model of Conspectus for online resources by using mechanistic quality factor. Based on some empirical statistics about resource use behaviour such as collection rate, use rate, search rate, the mechanistic quality factor was calculated and applied to each subject by adjusting its acquisition level of Conspectus. according to the result of this study, Acqusition levels of the subject such as technical science which shows higher in use rate, and those such as history and social science which show higher in search rate, should be adjusted to a higher acquisition level, and those of others to the same or a lower level.

This study is concerned with analysis of all the reviews published by the reviewing periodicals, The Book Review Culture and The Korean Publishing Journal, from 1991 to 1993. The result of analysis for 736 reviews are followed： 1) The percentage of reviews in the field of philosophy & religion, literature ＆ language, science ＆ technology is lower than the percent-age of books published. But in the field of history and social science the reviewing is proportionately higher than the publishing. 2) Book reviews are prepared by professors, literary reviewers, researchers, and experts in the particular subject field except librarian. 3) Basic elements of reviewing are the career and view point of author, trends of suject field, content, value, omissions, limitations, and format of book, reader's level, etc. Ideal method of book criticism may be summarized as follows： 1) The criterion of book selection are the book's value, the social . demand, and the proportion of titles published. 2) For the unbiased criticism, it should be written by the experienced librarian rather than the experts of particular subject field. 3) Book criticism need to provide not only guide to new books but also interpretation and evaluation about each book for its reader.

The purpose of the study was to investigate the effectiveness of ankle mobilization on neck and shoulder position. One hundred volunteers, aged between 18 and 26 years (mean age 22), were recruited and each subject was divided into four mobilization groups by their body type, which is based on the concept from 'general coordinative manipulation' and a control group. Ankle mobilization was applied based on their body type and no mobilization was applied on those of the control group. The positions of shoulders and neck were measured in comfortable standing posture. All measurements were taken before and after ankle mobilization from each subject in mobilization groups and those of control group was measured twice between ten minutes by a different tester on three different occasions. Twenty subjects were in each group basis of their body type and a control. In the position of neck and shoulder, all subjects regardless group showed significantly changed their neck
