The purpose of this study is to propose the expansion of headings for digital trends of Korean Decimal Classification. In order to achieve the purpose, this study first analyzed the change process of classification items related to digital resources in DDC and KDC. Second, subject names related to digital in LCSH and Korean National Library Subject Heading were analyzed. Third, comparisons between the items related to digital of DDC 23rd with LCSH and KDC with Korean National Library Subject Heading were conducted. The result of comparative analysis was identified that KDC 6th edition faces with difficulties in reasonable classification because item names related to digital of KDC 6th edition have 11 items. Therefore, the item related to digital has to be expanded to new classification item name and has to add include notes and class here notes in KDC.

The purpose of this study was to propose the improvements for high quality of National Library of Korea (NLK) Subject Headings List which was developed as a subject access tool in 2002. For this study, literature review, case study for subject headings lists of national libraries, and data analysis of headings and relationships were performed. Several problems were found as follows: inconsistency of subject headings descriptions, unclear and unnecessary relationships among headings, inconsistency of hierarchical relationships, lack of currency, incorrectness of classification numbers, duplication of newly requested terms, and assignment of non-preferred and unregistered terms in bibliographic records. Focusing on these problems, modifications of subject headings and bibliographic records, installation and operation of an review committee on subject headings, and supplementation of a manual were suggested to improve NLK Subject Headings List.

This study compares and analyzes the numbers and characteristics of Korea-related subjects included in the 2008 Japanese edition of the National Diet Library Subject Headings (NDLSH) and the $2^{nd}$ edition of the Chinese Classified Thesaurus(CCT). The analysis results show that 258 subjects, approximately twice as many as 137 subjects in CCT, were found in NDLSH. There are more pure subjects that exclude the references in CCT than in NDLSH. On the other hand, much more subjects are found in NDLSH in the event that personal names, corporate headings, and subjects combined with detailed headings are included. Meanwhile, more subjects are relatively engaged in the fields of politics, diplomacy, and military in CCT because CCT is characterized by socialism and by being a pro-North Korea. Moreover, the considerable numbers of subjects reflecting North Korea's viewpoint are included in CCT. NDLSH changed only recently the names of both South and North Korea into the "Republic of Korea" and the "Democratic People's Republic of Korea", respectively. On the other hand, CCT more frequently uses "Joseon" than "Korea", and the distinction between the names is unclear. CCT thoroughly supports the stance of the developed country, directly involved in the disputable subjects between two countries such as "Dokdo", "the East Sea", "Dumangang", and "Baekdusan". Both heading lists consider "Balhae" as part of Chinese history in CCT, which has ignored the position of Korea.

The purpose of this study is to analyze the historical process and characteristics of subject headings related to Korea, China, Japan in the LCSH, from the first edition to 31th ed. The analytic results show that the headings in the 31th edition include in Korea 713, China 1,742, Japan 2,647, compared to Korea headings 4, China headings 49, Japan headings 24 in the first edition. Some subject headings considered important and essential are left out. We can also recognize the some headings are relatively too subdivided. The omitted and insufficient Korean, Chinese, Japanese subject headings are considered to be tied up with library policies of LC. Therefore our active support such as donation are being called for collecting more detailed analysis of Korea, China, Japan-related publications in LC.

In 2000, North Korea developed and published a two-volume, <Classification-Search Term Dictionary> and is currently used throughout North Korea. The purpose of this study is to examine the development process of the classification schemes of the North Korea after liberation and to understand the contents, composition, and principles of the <Classification-Search Term Dictionary> published in 2000 and revised in 2014. Until now, all the studies of the North Korean classification schemes were studies on the <Book Classification Scheme> published in North Korea in 1964, and there has been no discussion on North Korea's classification schemes since then. The first volume of the <Classification-Search Term Dictionary> consists of 'classification symbols - search terms', and the second volume consists of 'search terms - classification symbols'. Volume 1 is based on the <Books and Bibliography Classification Scheme (1996)>, and there are a total of 41 main classes in five categories. Volume 1 allocates 1 main class (11/19) to 'revolutionary ideas and theories', 8 main classes (20~27) to 'natural sciences', 19 main classes (30~69) to 'engineering technology and applied sciences', 12 main classes (70~85) to 'social sciences', and 1 main class (90) to 'total sciences'. Volume 2 is similar to subject-headings. North Korea's <Classification-Search Term Dictionary> is the first classification scheme introduced in South Korea and is expected to be the starting point for future studies on the establishment of the standard unification classification schemes.

This study aims to provide an understanding and information of the new curriculum by comparing 12 kinds of Technology and Home Economics textbooks(Clothing Life section) that reflect the 2015 revised. Results revealed that most of the textbooks' unit arrangements consisted of the introduction, development, and summary. In addition, we examined the advantages of current textbooks and suggested future improvement directions. The analysis of volume revealed that the largest textbook was 38 pages and the smallest was 24 pages. In addition, the learning objectives by unit a little bit differed for each textbook. The illustrations in the textbooks were primarily figures followed by photographs, tables, and graphs. The number of textbooks with the largest amount of illustrations was 69 and those with the least were 38, indicating a significant difference. As for career, 8 textbooks of 12 textbooks reflected related contents. The number of units, volumes of the clothing life section, and ratio of illustrations used in each textbook were different, but the contents were similar. Most of the contents of the 2009 textbooks are mostly included and the meaning of clothing, clothing purchasing, dress code, and creative clothing life are added on 2015 revised textbooks. Furthermore the educational objectives have extended to wide range and provides concrete guidelines to foster human resources that will lead the future society.

This study explored the effects of pre-service elementary teachers' inquiries into science class dilemmas. By closely examining the characteristics of the pre-service teachers' inquiry processes and changes in their educational decisions, the effectiveness of using dilemmas as part of teacher education was determined. Twenty fourth-year university pre-service teachers participated and conducted inquiries into science class dilemmas over seven weeks. Based on pre- and post-questionnaires, KWHL tables, inquiry reports, discussions, and group class presentations, the major factors that influence the pre-service teacher's decision-making changes were extracted. The pre-service teachers found the science inquiry process meaningful when exploring the science topics covered in the dilemmas, and claimed that elementary school students would be able to engage in meaningful science explorations if they learned science through inquiry. Furthermore, the pre-service teachers explored the thinking processes and background knowledge of the students in different ways. Documents such as teacher's guides and the curriculum were examined and the students' thought processes were identified through interviews with the teachers and students, which were found to reflect their educational decision-making. Moreover, it was recognized by the pre-service teachers that depending on the situation, alternative teaching methods were possible. The focus on the unstructured dilemma problems provided the pre-service teachers with problem-solving situations that triggered scientific inquiry and exploration of student thinking and revealed the complexity of science teaching and learning. Based on these results, the teacher education implications for using dilemma cases are discussed.
