This study investigated general problems concerning the clothing and textiles field in the KDC 5th edition based comparative analysis academic characteristics and classification system, and suggested on some ideas for the improvements of them. Results of the study is summarized as follows. First, the classification system of the clothing and textiles field is generally divided by costume, dyeing engineering, leather & fur processing, textiles and textile industries, manufacturing clothes, management of clothing, and textile arts. Second, I proposed improvements based on analyzing problems of KDC 5th to the clothing and textiles field from the collection database at the National Library of Korea. Third, basically improvements of KDC system was based on the knowledge of the clothing and textiles field. I tried to maintain as the KDC existing classification system was to retain as much as possible, and to move between items was minimal.

This study investigated general problems concerning the tourism field in the KDC 6th edition based comparative analysis academic characteristics and classification system, and suggested on some ideas for the improvements of them. Results of the study are summarized as follows. First, academic field of tourism is generally divided into a general tourism, tourists, tourism attraction, and tourism media, but classification system of tourism is limited to parts of tourism attraction and a general tourism. Tourism attraction and tourism media are dispersed among the subject. Second, I analyzed on tourism from the collection database at the National Library of Korea. Based on analysis of the data. the keyword frequency of tourism management, type, development, psychology, industry, and convention etc. was relatively high. Third, modified classification of items was basically performed through the academic characteristics of the tourism and the keyword analysis, and maintaining the existing KDC classification system caused less confusion as much as possible. Also, based on this matter was added to the relative indexes.

General-purpose classification scheme encompasses all subject areas, While the whole classification scheme is constructed by library studies experts, structure and preparation of each specific subject area's classification should be referenced to that specific subject. In order for the whole system to be practical and useful classification scheme, not just a simple collection of each subject area's scheme, it is necessary to set the rule for properly distributing the amount of classification items, and the collections assigned to these items. The rule to set the distribution of items based on the amount of document collections is called 'literary warrant'. This study examines actual status of assignment of each classification items to information resources, as a result of application of Korean Decimal Classification, and then suggests a way to improve these practices.

The purpose of this study aims to provide possible suggestions for the improvement of KDC 5th ed. in Jurisprudence Field. The research methods are as follows. First, to analyze academic fields in Jurisprudence, the contents of Jurisprudence introductory books are investigated. Second, to find out the problem of KDC Jurisprudence field, comparative analysis is done on the three classification schemes - KDC, DDC and NDC. Third, curriculum of domestic law schools are reflected. If above suggestions are adopted, effective literature classification scheme which is suited to domestic circumstances will be certainly prepared.

The KDC is the most widely used classification system in the elementary school libraries of Korea, but it is only published in full edition. This study is to development abridged KDC edition for elementary school libraries as the subject of KDC. In order to do this, the present writer carried out as follows; to analyse the present state of an class in KDC, to analyse a distribution chart of a class in an practical books and to comes up with a plan of abridged KDC edition as the grounding in the foundation of volume a collection of books. The abridged edition for elementary school libraries is a structural hierarchy of the corresponding full edition which it is based, and is intended for general collections of 20,000 titles or less.

Constructions and Architecture fields were divided into Architecture engineering and Architecture in the 5th edition of Korean Decimal Classification (KDC), but those were combined in the 6th edition of KDC published in 2013. The purposes of this study are to find problems and to suggest modifications through comparing and analyzing the 5th and the 6th editions of KDC, Dewey Decimal Classification, Nippon Decimal Classification and Universal Decimal Classification. The necessity of reclassification, a long classification number for History of Architecture and addition of categories of traditional building and architectural engineering are required to improve the 6th edition of KDC and the improvements and modifications of those problems are suggested.

Objective of this research is to point out problems of geographic division structure in current Korean Decimal Classification System and provide solutions. For this purpose key classification methods were divided to decimal and non-decimal classification methods and analyzed for geographical division principles. In addition, national institutes regional division standards from Korea, USA and Japan were researched. Through these analysis, we provided suggestions to improve the table of geographical division in KDC4 including public institutions administrative district classification structure relations and consistency, and other regional divisional standards (proposal) instead of typical administrative district reflecting various geographical conditions.

Carry lookahead(CLA) circuitry of decimal adders is proposed aiming at delay reduction. The truncation error in calculation of monetary interests may accumulate yielding a substantial amount of errors. Binary Coded Decimal(BCD) additions. for example, eliminate the truncation error in a fractional representation of decimal numbers. The proposed BCD carry lookahead scheme is aiming at the speed improvements without any truncation errors in the addition of decimal fractions. The delay estimation of the BCD CLA is demonstrated with improved performance in addition. Further reduction in delay can be achieved introducing non-weighted number system such as the excess-3 code.

In this paper, we proposed a mixed algerian to improve decimal division speed. In the binary number system, nonrestoring algorithm has a smaller number of operation than restoring algorithm. In decimal number system however, the number of operations differs with respect to quotient values. Since one digit ranges 0 to 9 in decimal, the proposed mixed algerian employs both nonrestoring and restoring algorithm considering current partial remainder values. The proposed algorithm chooses either restoring or nonrestoring algerian based on the remainder values. The proposed algorithm improves computation speed substantially over a single algorithm decreasing the number of operations.

The purpose of this study is to develop internal tables in Christian religion in the 5th edition of Korean Decimal Classification. The scope of the Christianity, its structure of various classification schemes, and the concepts of internal tables were analyzed. The contents of several textbooks were analyzed for the scope of the discipline and the classification schemes and internal tables of DDC, UDC, NDC, LCC, Classification of the Library of Union Theological Seminary and the Classification of the Korea Theological Library were compared. And then, internal tables in Bible, sermon, worship, church history were built and those tables were evaluated by librarians and experts in the fields. And finally, internal tables of the Christiainity and new headings were suggested. New internal tables in Christianity will increase the effectiveness of information retrieval and it will provide a foundation for developing internal tables in other disciplines.
