Due to rapid internet supply and the increase of electronic resources including network resources, there has been a sudden change in cataloguing fields. To deal with rapid changes, IFLA revised cataloguing rules for electronic and continuing resources; ISBD(ER) and ISBD(CR), JSC(Joint Steering Committee for Revision of AACR) has published the 2002 revision of Anglo-American Cataloguing Rules, Second Edition. Major changes in both content and format make the release of the 2002 revision momentous. This study is to analyze activities of JSC and rule revisions of AACR2R 2002 edition, expecially in regards with concepts of change to rule 0.24, new categories of bibliographic materials, changes to chapter 3(cartographic materials), chapter 9(electronic materials), chapter 12(continuing materials), definition of a new terminologies, changes in MARC 21 coding, and issues concerned with revision of KORMARC.

This study aims to present a revised draft of KORMARC bibliographic format that was first revised in 2014. To this end, data collection and analysis methods are as follows. First, the opinions of cataloging working groups for revision of KORMARC including the National Library of Korea (NLK) and KERIS were collected and analyzed. Second, work guidelines used in libraries or cooperative catalog systems were analyzed. Third, by comparing MARC21 update No.32 (June 2021) with the KORMARC bibliographic format, elements that need to be reflected in the KORMARC revision were derived. Finally, issues that have been raised in previous studies or that require further discussion were examined. Based on these analysis results, an outlines of the extension and deletion of KORMARC fields, subfields, and indicators, and supplementation of application guidelines and examples were derived. The final revision directions were finalized after collecting expert opinions, the working group reviews, and comprehensive opinions from the library community.

In this paper, a dual-band Koch Snowflake antenna is proposed for wireless communication systems. Fractal geometry, CPW-feed and stepped ground planes are used to improve the impedance bandwidth. By properly introducing a hexagonal split-ring slot to radiating element, a lower frequency band is generated. The proposed structure is fabricated and tested. Experiment results exhibit dual-band of 0.73-0.98 GHZ and 1.6-3.1 GHz which makes this antenna suitable candidate for GSM900, GSM1800, UTMS2100, Wi-Fi 2400 and LTE2600 bands. In addition, a good radiation pattern, a satisfactory peak gain and a radiation efficiency, which reaches 95%, are achieved.

The Korean Library Association has developed the Korean Cataloging Rules, fourth edition(KCR4) in 2003 and the National Library of Korea developed integrated version of KORMARC formats in 2006 on the basis of KCR4. Many educational institutions and libraries are currently cataloging based on KORMARC. Nevertheless, we have encountered many problems on KCR4 and KORMARC formats which needed to be modified. This study is aimed at pointing out the problems of KCR4 in describing 245 field which has a crucial and important role. Therefore, this study proposes the improvement methods of the use of parenthesis and subfield code in 245 field, and presents a description format of volume number, statement of responsibility and joint works including more than four persons.

FRBR, as is new conceptual model of bibliography based on entity-relation model, direct to revision of AACR. OCLC and other bibliographic utility develop algorithm that cluster relative bibliographic records automatically, which were derived from one original work, and web-based prototype for FRBR browsing. But the state of domestic research level stay at conceptual reconsideration of FRBR model.7his study focused on analyzing FRBR algorithm and application of KORMARC database.

This study is a preliminary study to suggest an idea for the establishment of the Korean standard authority database system for Korean libraries. It analyzes in detail the current status of the mjor libraries in Korea operating authority system Because the authority work is very hard for a library to accomplish for its costs and efforts needed, it is desirable to establish and maintain the system through cooperative venture. It also investigates the problems to be followed and suggests the possible improvements for the system.

O-ring seal is an essential component in various mechanical apparatuses for a sealing of oil container and pressure vessels. This paper presents the sealing pressure and compressive contact behaviors of hi-polymer O-rings, which is made by an outer shell of FFKM material and an inner solid ring of FKM one. The contact normal pressure and its ratios are measured by experimental method with an automatic control system of the working temperature and analyzed numerically by using the non-linear Marc FEM program. The results show reasonably good agreements between the computed FEM results and measured ones when the operating temperature is kom normal temperature of $18^{\circ}C$ and a high temperature of $300^{\circ}C$ But the compared values between the computed and tested results show a little difference because of the increased temperature, which is related to the non-linear parameter of the O-ring material. Bi-polymer 0-ring shows a good contact normal stress and compression behavior for a given operation temperature and compression ratio.
