The purpose of this research is to analyze the differences between electronical engineering class in KDC3 and electronical engineering class in DDC 19. The results of the study can be summarized as follows ; 1. The characteristics of the classification items in classification schemes of the electronical engineering fields is that KDC is classified by the vacuum tubes, electron tubes, special tubes, computers etc and DDC is classified by the microwave electronics, short-and long-wave electronics, X-ray and gamma-ray electronics, computers etc. 2. There is a blank in KDC and there are three blanks in DDC of the electronical engineering fields, but the total classification items number is much more in DDC than in KDC. This means that DDC is more classified than in the special classification items. 3. Classification items over 70% in the total classification items of computer fields in KDC, are classified a classification items of the short-and long-wave electronics in DDC. 4. There is a blank of computer fields in KDC and there are three blanks of computer fields in DDC, but the total classification items are many eighteen items. This means that DDC is more classified than KDC. 5. The sections of computers in DDC were established the 621.38195 classification item and the subsection of analogue computers in DDC were established the 621.381957 classification item and the subsection of digital computer in DDC were established the 621.381958 classification item. As we have seen, because of the development in technology and the subdivision of knowledge, the number of items is increased, and the terminology also become simplified and specified in the field of electronic engineering in KDC and DDC.

KDC(Korea Decimal Classification), which is representative literature classification scheme in Korea, was revised and published in 1996. The purpose of this paper is to suggest a reform measure after detecting out issues and problems associated with the KDC 4th ed. through the result of lecture. The outline of suggestions are as follows : (1) There are not all items of auxiliary tables in relative index. (2) Auxiliary table 2 (Geographic Areas) is not detailed. (3) The manual for the shake of efficient usage is nonexistent and notes are poor in content. (4) Sufficient minimax and alternatives must be setted up for efficiency usage. (5) Some parts of the main schedule are disorder and not logical.

The purposes of this study are to review characteristics and research areas of environmental studies; to compare and analyze environmental studies in research classifications and Korean societies from Korea Research Foundation(KRF) as well as decimal classification systems such as KDC, DDC, NDC and to suggest several modifications for environmental studies in KDC for the next edition. First of all, environmental philosophy, environmental sociology, environmental education, environmental toxicology, environmental architecture, and environmental geography are suggested to add to the main schedule in KDC and -0276 green technology(environmental technology) is suggested to add to Table 1. Standard subdivision. And new classification numbers for environmental law and environmental public administration are suggested in law and public administration.

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.

Library classification schedule IS based on the classification theory, principle and the system of the classification of science. It should be consisted of the basic principle of library classification which should use the library materials effectively. Continuous study and research on the each subject field of the discipline are essential for keeping up with the transformation of each learning field and the change of modern society. In this paper, I studied comparatively the sections and subsections of the management in KDC, DDC and NDC and reviewed the academic systems of each subject area in the management. I tried to compare the relationship beween the structure of library classifications and academic systems for the more specialized subsections of the management. KDC is influenced by the principle and structure of DDC, but I found that KDC is more similar to NDC than DDC in the sections and subsections of the management. Being un sufficient of subsections of KDC and NDC, they are not enough for the expansion and specialization of the subsections in the management. DDC is necessary to re-schedule for the proper expansion of 650 and 658 with reflection of the importance of that sections and academic systems. In this study, I adoped 9 sections of management, (1) Management policy (2) Administrative organization (3) Personnel (4) Office management and business information management (5) Marketing (6) Financial management (7) Production management (8) Accounting (9) International management. It would be necessary for us to study continuously about the specilized subsubsections of the management for the more professional classification.

The purpose of this research is to analyze the differences between literature (Belles-letters) class in DDC 19 and literature class in KDC 3. The results of the study can be summarized as follows : 1. The section of philosophy and theory of literature in DDC was subdivided according to the properties as including subsection of theory of criticism but KDC didn't subdivide this section. 2. In DDC, the subsections of 'rhetoric in specific languages' and 'rhetoric of specific kinds of composition' in rhetoric section was established and can subdivide according to each languages and subjects. These considerations can be useful as compared with KDC. 3. In DDC, collections or criticism of several literatures in specific forms can be more subdivide according to specific aspects or features dealing with in the collections or criticism by a n.0, pplying Table 3-A when specified more than the literary form. 4. Reviewing a notational rank to be assigned in literatures of specific languages, Latin literature and Classical Greek literature to be ranked in division in DDC was established as subsection in KDC to treat them as literatures of minor languages. 5. The DDC can sometimes a n.0, pply, in literatures of all languages, the notations of Table 3 to be subdivided again as specific kinds of literary forms, but KDC subdivided literary forms as specific kinds of each forms in only Korean, Chinese, Japanese literature. 6. In DDC, even literatures of minor languages are provided with 'the period table for the specific literature' under each literature of specific languages in schedules and these period tables can be a n.0, pplied a n.0, ppropriately, but period numbers in KDC was established in only Korean, Chinese, Japanese literature. 7. The optional use of letter prefixes or special numbers such as 828.99 to distinguish literatures of countries other than the "mother country" which makes the use of period tables feasible, but the KDC can only use to distinguish without the function of dividing a period such as DDC. 8. According to a n.0, pplying Table 3 and 3-A also in literatures of specific languages(810-890), a literature of specific languages, a specific literary form in literature of specific languages and a literature or literary form of specific period, in case of a n.0, pplying 'form divisions 08-09', can subdivide again by a specific aspect or feature dealing with in the works when specified. 9. For grasping the rate of subdividing, after selecting several sample-titles in literary field, they classified by DDC and KDC and gave a definite score in accordance with analytic small subjects. According to the results, the rate of subdividing in literature class of KDC is proved as less 22.8% than DDC. than DDC.
