The purpose of this study is to investigate the problems concerning music schedules of KDC. The object is especially arrangement of 670 music in the 4th edition of KDC. In this study, therefore, the development of 670 music division from the 1st edition to the 4th edition of KDC were examined first as the backgrounds. Then the expansion aspects and their problems of 670 music division in the 4th edition of KDC were analyzed. And based on the findings, some suggestions to solve the problems were proposed. These problems of music division of KDC originate in the lack of professional understanding of music, structural problem of KDC itself, and very comprehensive and contradictory revision policy. To make the KDC improved as standard classification scheme of Korea, mutual cooperation of the classifiers and specialists in music is inevitable.

This study is intended to present methods improving the classification system of KDC education fields after comparing and analyzing the academic system of education, classification system of KDC, NDC, DDC and LCC, and that of the research field classification system of National Research Foundation of Korea. The results of the analysis have revealed that it is required to improve and correct the KDC 5th edition of education including the addition of classification items that reflect the trend of academic development, proper development in the rank classification terms of education detailed fields, addition of detailed subjects, errors of classification symbols and omission of correlative indexes in the classification items. This study has proposed improved methods to solve those problems.

As the development of advertising industry and media the research about an advertisement get accomplished. As the result information resources called on the advertising materials are on an Increasing trend. However, it looks into the classification system In advertising field of KDC, the problems are as the follows : (1) the classification items are too incomplete, (2) the main class is badly arranged. The reason have no regard for the correlation with a science. So, it gives rise to confusion to the librarian and user. The purpose of the study is to present the improvement plan on the classification system in advertising field of KDC. In order to build the improvement plan, the four steps are utilized. The first step Is to investigate the characteristic of sciences on advertising and a type. The second one is to survey the current status of the library classification as KDC, NDC, DDC, and LCC. The third one is to analyse the classification system of library and web site on the advertising. The forth one is to grasp the problems on the classification system In advertising field of KDC.

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.

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.

In this paper, We propose a new Kerberos certification mechanism that improve certification service based on PKINIT that announce in IETF CAT Working Group. Certification between area connected by chain through PKINIT that use X.509 and DS/DNS mutually for service. In order to provide regional services used private key and public key, X.509 of PKINIT is employed on session part and Kerberos's private key on actual authentication part. New mechanism be reduced communication overload doing to simplify certification formality between Client and remote KDC by KDC's certificate use to get ticket in remote sacred ground and remote KDC's reaffirmation process omitted.

This study is to analyze and suggest the KDC's facet structure. KDC is using the Decimal Classification's facet structure. New suggestions are : Clearly use standard subdivisions and add instruction like 'Add to base number $\~$ notation $\~$ from table $\~$' : auxiliary tables contents are need to revise and expand to make a add table found in schedules and provide numbers to be added to designated schedules numbers are necessary.
