This study compares and analyzes the classes in the major special areas in the sociology, called “branch sociology,” included in the Korean Decimal Classification 4th edition and Dewey Decimal Classification 21st edition. Especially it analyzes the related classes of specified areas (branch sociology) of sociology including those of arts and sports, sciences, languages, society, region, etc. class by class. In this analysis two systems show many differences in the classes included and in the locations of some classes. This analysis can be useful for the future revision of KDC.

Recently, the table of contents (TOC) has been becoming increasingly accessible and utilized. The study conducted descriptive statistics and comparative analysis of the table of contents in terms of parts of speech and subject in text. For this purpose, this study chose the books of the social sciences field from acquisition lists of an academic library, obtained Dewey class numbers of target books from KERIS union catalog, and extracted TOC data from online bookstore. Morphological analysis was performed on each book titles and TOCs, and descriptive statistics and frequency analysis were carried out. As a result, nouns made up roughly half of the morphemes of titles or the TOCs. TOCs had about 50 times more nouns than titles. The percentage of unique nouns that appeared only in the table of contents is estimated to be 95.2% of the TOC's total nouns. The table of contents also showed a differences in its lengths depending on the field of social science.

The paper discusses the nature of Knowledge Organization Systems (KOSs) and shows how these can support digital library users. It demonstrates processes related to integration of KOS like the Dewey Decimal Classification, $22^{nd}$ edition (DDC22) in DSpace software (http://www.dspace.org/) for organizing and retrieving (browsing and searching) scholarly objects. An attempt has been made to use the DDC22 available in Bengali language and highlights the required mechanisms for system-level integration. It may help a repository administrator to build an IDR (Institutional Digital Repository) integrated with SKOS-enabled multilingual subject access systems for supporting subject descriptors based indexing (DC.Subject metadata element), structured navigation (browsing) and efficient searching.

Recently, information on international trade goes on increasing in quantity because of the globalism and many related areas of the field. Most of libraries and informatin centers in Korea are using Dewey Decimal Classification(DDC), Library of congress Classification(LCC), and Korean Decimal Classification(KDC) to classify library materials on the subject. The application of three classification shcemes, DDC, LCC, and KDC were queried to determine the classification of materials on international trade. And analyses of the parts of international trade in three classification shemes were done in order to identify what major changes have made with the development of the field. There was subject scatter in DDC and LCC; there was an overlap among the classes of the three systems; and there was little change between present editions and the previous editions. The revision for international trade field of the KDC, the 4t edtition was suggested to help cover some deficiencies of the classification scheme. Inorder to develop a better KDC, the 5th edition, continuous revisions based upon the opinions of subject specialists and catalogers in the field are highly recommended.

This study is to suggest ways to supplement terms and notes in the field of parapsychology and occultism in the KDC 6th edition. In order to this study, the comparative analysis of KDC and DDC analyzed the classification system and change process of classification items, classified data in parapsychology and occultism. Based on this, the analysis academic characteristics and problems of parapsychology and occultism field were analyzed. As a result of the analysis, the lack of notes and inadequacy of terms caused confusion in classification, to solve this problem, this study suggests the solution of adding notes of sub-items, changing term of 187.2, 187.3, 187.4, 187.5.

The purpose of this study is to analyze the structural model of classification, to compare enumerative schemes with faceted schemes and finding the facted schems used in the Dewey Decimal Classification. The Structural model of classifications can be divided to enumerrative schemes and facted schemes(analytico-synthetic schemes). Enumerative schemes represent the various kind of subject in different ways and have to not only list all existing combinations of subjects but also any of potential subjects. Faceted schemes is the decomposition of concepts into all possible characteristics which are known as facets. DDC was originally created as enumerative, but over 20 editions has moved increasing towards synthetic features such as the add instructions, and the seven auxiliary tables. Many DDC class numbers found in the Schedules may be subdivied by another number(or part of it) that has been drawn from the Schedules or auxiliary tables. This process of subdividing class numbers is called number building and it can be done only when there are number building instruction in the Schedules or Tables.

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.

This paper examines 'Religion Class' in the scheme of the DDC. The major findings of the study are summerized as follows. 1. The first edition of DDC was published in 1876 in order to classify Amherst College Library collections. In spite of the continuous study and revision of the experts, the frameworks of the DDC systems are still kept unchanged. Only their subdivisions, reflecting those developments in the academic world, are developed and detailed more sophisticatedly. 2. The division of 200 does not function as generalities for all class of religion. Therefore, it is necessary to amend the division of 200 to serve generalities for all the religions of the world. 3. Standard subdivision for the christian religion and for the non-christian religion is different. So, the mnemonic nature has become weakened due to the dual standard subdivisions and the classification number becomes much longer and complicated. Therefore, one standard subdivision for all religions of the world is required. 4. Religion science was organized in late 19 C and developed continuously, but the DDC does not accomodate the religion science as a science. Accodingly, the DDC should be revised recognize religion science as a science not the christian science. 5. The deployment of classification scheme in Dewey's 200 is severely biased. That is to say, 9 division were assigned for christian religion, whereas only 1 division was assigned for non-christian religion. Therefore, an adjustment should be made to allocate subdivisions equally to all religions of the world. 6. General classification order of religion is prehistoric, primitive, ancient, modem and world religion in religion science. But, DDC does not accept this general classification order of religion, sticking to the biased expansion towards christianity. Therefore, DDC must adopt the general classification order of religion in the religion science. 7. Lastly, because of the limitation of decimal notation in DC, DDC does not accomodate new subject equally and classification number becomes longer. Therefore, centesimal expansion is proposed in order to make the classification number short, to enlarge its capacity of inclusion of new subject and to maintain consistency in the scheme.

In this study, Two divisions(language and literature) in schemes of the DDC are discussed. And the adaptation of these divisions to the minor or oriential countries are seggested. In spite of the continuous study and revision of the experts, the frameworks of these systems are still kept unchanged. Only their subdivisions, reflecting those developments In the academic world are developed and detailed more sophisticatedly. Of those subdivisions in DDC, especially the two subdivisions of language and literature are seriously unbalanced. The two divisions give the attention too much to the Western including the English, Deutsch and French. Relatively the languages and literatures of the other nations are treated lightly. It results more problems to the Oriental and the minor nations. So, the libraries of these nations should modify the schedules and develop the subdivisions items of the local emphasis. Considering these problems the historical changes of the DDC system in the languages and literatures are clarified and the problems occurring from unbalanced allocation of the classed items are examined.
