Name Authority Control is useful not only to manage author information but also to gather other names of authors in order to provide access points in libraries and other institutes. The purpose of this study is to find problems through comparing and analyzing Literature Translation Institute of Korea Author Database, Korean name authority records of national libraries in the U. S., Japan and Korea. The results of the study are as follows. First, Literature Translation Institute of Korea Author Database missed some useful information about Korean writers in translated books in other countries. Second, the name authority file of Library of Congress and National Diet Library did not include the variant names, dates of authors' birth and death date, and filled out incorrect variant names with some birth and death dates. Third, English and Chinese character variants of Korean authors were not found in the National Library of Korea. To solve these problems, revisions of Korean author database, open access to National Library of Korea name authority file, and a strong participation of VIAF were suggested.

Authority control enables us to retrieve information accurately by coordination and cross reference of headings. It is considered that authority control is needed in machine readable catalogs as well as in conventional catalogs. Taylor, Maxwell and Frost divided automated authority control systems into major vendor and network systems then available into two groups. The first group was defined as a system that processes a library's machine readable catalogs on the tape against an automated authority file. The second group offers an online access to catalogs and authority records. This group was further subdivided into linked or integrated systems and unlinked systems. If authority work is shared with many libraries the costs can be considerably reduced and the quality of catalog data base can be controled by standardization of headings used in participating libraries. The NACO is a project for sharing of authority records started in 1977 by L.C. And LSP furthers the ability to share authority records. A project as the NACO is necessary not only in America but also in the other countries The responsible organizations for national bibliographies of the countries must take much interest in these matters.

The authorized form is called the heading must be unique and consistent. Without both uniqueness and cosistency, retrieval from the bibliographic database will not be optimal and in some cases may even be impossible. But the authority control is extremely expensive, because it is labour-intensive and dependent on professional investigation and judgement. In fact, it is by far the most expensive function in all of bibliographic control. The processes used to determine the form of access points. maintain. use. and evaluate very accurate authority records reduce the efficiency to generate or merge bibliographic items without modification from any national level bibliographic utilities as well as individual library. In this paper non-authority control system was suggested to solve the disadvantages of authority work. The apparent advantages of the non-authority control system are it is easy to determine the heading, input the bibliographic data. integrate the access points into an existing file, and generate and merge bibliographic data without modification. In addition, non-authority control system can be transmitted into online information retrieval system conducted with a mixture of controlled vocabularies and natural language.

Name authority control is important for not only library catalogers but also end users, since it provides uniform access points. The national libraries in Japan and the United States have constructed and controlled authority records for writers from early days, and have provided them on the web sites. The purposes of this study are to extract common fields and differences in Japanese writer's name authority records of the U.S. and Japan, and to propose the ways of desirable description of authority records in Korea. Several suggestions of building authority records in National Library of Korea such as open to the pubic of authority records, provision of various forms of authority files, suggestion of the ways of writing the names of foreign writers, and the links between the authority records and library catalogs for retrieval are proposed.

The purpose of this study was to conduct interviews with librarians who have experience in establishing local authority data by participating in the national authority sharing system of the National Library of Korea and to understand librarians' recognition and support for the joint utilization of national authority data. For this purpose, a total of 10 librarians who participated in the national authority sharing system project were interviewed by telephone using semi-structured questionnaires. Through this, it was possible to investigate the benefits, difficulties, utilization plans, revision plans of headings, and opinions on necessary support. The results of this study showed that the participants recognized that the joint utilization of national authority data provides the basis for the authority work of the local library and brings about the efficiency of the authority work, but they recognized the difficulty of modifying, selecting, creating new data, lacking knowledge, and lacking support system. The necessary support for the joint utilization of national authority data was provided with education and manuals related to authority, provision of rules related to authority that fully consider the position of the institution, budget and manpower support for system development and maintenance, establishment of communication channel and council, system and data advancement, and incentive to participating libraries. Based on the results of the study, the method and direction for the future operation of the joint utilization of national authority data were presented.

Objectives: Glide path preparation is recommended to reduce torsional failure of nickel-titanium (NiTi) rotary instruments and to prevent root canal transportation. This study evaluated whether the repetitive insertions of G-files to the working length maintain the apical size as well as provide sufficient lumen as a glide path for subsequent instrumentation. Materials and Methods: The G-file system (Micro-Mega) composed of G1 and G2 files for glide path preparation was used with the J-shaped, simulated resin canals. After inserting a G1 file twice, a G2 file was inserted to the working length 1, 4, 7, or 10 times for four each experimental group, respectively (n = 10). Then the canals were cleaned by copious irrigation, and lubricated with a separating gel medium. Canal replicas were made using silicone impression material, and the diameter of the replicas was measured at working length (D0) and 1 mm level (D1) under a scanning electron microscope. Data was analysed by one-way ANOVA and post-hoc tests (p = 0.05). Results: The diameter at D0 level did not show any significant difference between the 1, 2, 4, and 10 times of repetitive pecking insertions of G2 files at working length. However, 10 times of pecking motion with G2 file resulted in significantly larger canal diameter at D1 (p < 0.05). Conclusions: Under the limitations of this study, the repetitive insertion of a G2 file up to 10 times at working length created an adequate lumen for subsequent apical shaping with other rotary files bigger than International Organization for Standardization (ISO) size 20, without apical transportation at D0 level.

Some conclusions can be derived form the study : 1) The script of Japan author's name for 3 years(1960-1962, not published by the National Assembly Library but by Korea Library Association)and that of 1963's was arranged by their mother tongue although they had not the "author index". 2) "Periodical's Index" which the publication of National Assembly Library was not accept the principle that the person's name should be pronounce and script by one's mother tongue. It means that the Library was not accept the uniqueness of personal name. 3) Because the arrangement of the same person's name is mixed with one's mother tongue pronunciation and Korean one that they are scattered each another. 4) The same surname and the same Chinese character has different arrangement because of pronunciation rule of Korean language. 5) The same person's name was regarded as a different one because of nonaccurate name transcription. 6) A Japanese name was transcribed as Hangul with Korean pronunciation. 7) A Japanese name was transcribed as Hangul with Korean pronunciation and added Chinese Character in parenthesis. 8) A same Japanese name was regarded as a different one when it was transcribed with Chinese character and Hangul. 9) The arrangement of a same person's name was different when between the surname and forename has one space and has not. 10) "Author Index" is not playing as a role of name authority file.a role of name authority file.

In this study, Linked Data was used for extending bibliographic data, because Linked Data provides shareable identifiers, data structures, and link information. Linked Data is especially efficient in expanding bibliographic data integrated with bibliographic ontology. Therefore, Linked Data and bibliographic ontologies were analyzed and available Linked Data was suggested. By linking between meta-data schemes, bibliographic data, and authority data, issues for the effective Linked Data sharing were suggested: 1) selecting proper Linked Data for each bibliographic organization, 2) linking between different Linked Data, and 3) developing their own Linked Data for each bibliographic organization.

Some conclusions can be derived from the study: 1. Person's name should be script by the one's mother tongue because of its uniqueness. 2. Japanese person's name should be script and pronounce their mother tongue for exchange and sharing of an academic information. 3. We can anticipate that Japanese language materials will be increase in near future. 4. The National Central Library which publish Korean National Bibliography must have to responsibility to lead other library. 5. The script of [Korean National bibliography] must contribute to standardization and national and Universal Bibliographic Control. 6. The area of education, newspaper, publishing are scripting Japanese person's name with script conversion schemes for Koreanization, devised by Ministry of Education. 7. The script of [Korean National Bibliography]'s name index can be used as authority file at selection of heading in library cataloging. 8. Most of libraries script Japanese person's name with Chinese character in Korean language pronunciation. 9. Korean Cataloging Rules (KCR) and Korean Machine Readable Cataloguing (KORMARC) description rules should be defined about the mother tongue script of Japanese person's name. 10. It is desirable to increase of credit of Readings in Japanese material course in college curriculum. 11. Because Japanese person's name is complex and variable that it is desirable to add Chinese character with mother tongue script.

Objectives: This study compared the amount of apically extruded bacteria during the glide-path preparation by using multi-file and single-file glide-path establishing nickel-titanium (NiTi) rotary systems. Materials and Methods: Sixty mandibular first molar teeth were used to prepare the test apparatus. They were decoronated, blocked into glass vials, sterilized in ethylene oxide gas, infected with a pure culture of Enterococcus faecalis, randomly assigned to 5 experimental groups, and then prepared using manual stainless-steel files (group KF) and glide-path establishing NiTi rotary files (group PF with PathFiles, group GF with G-Files, group PG with ProGlider, and group OG with One G). At the end of canal preparation, 0.01 mL NaCl solution was taken from the experimental vials. The suspension was plated on brain heart infusion agar and colonies of bacteria were counted, and the results were given as number of colony-forming units (CFU). Results: The manual instrumentation technique tested in group KF extruded the highest number of bacteria compared to the other 4 groups (p < 0.05). The 4 groups using rotary glide-path establishing instruments extruded similar amounts of bacteria. Conclusions: All glide-path establishment instrument systems tested caused a measurable apical extrusion of bacteria. The manual glide-path preparation showed the highest number of bacteria extruded compared to the other NiTi glide-path establishing instruments.
