The purpose of this paper is to present core elements of bibliographic records to effective cataloging a variety of information materials such as monographs, non-book materials, serials, and internet resources. At first, AACR2R bibliographic data elements, the minimal level cataloging, and core records proposed by Progrma for Cooperative Cataloging(PCC) in Library of congress are discussed. After that elements of Core Records, dublin Core, KORMARC, and AACR2R are compared. Upon the results, this study suggests mandatory common core elements and optional core elements for cost-effective cataloging to all kinds of documents including internet resources.

1876년 Cutter의 개념을 계승한 AACR2R의 편목의 3수준은 오늘날과 같은 전자환경에서 유용하다. 본 연구에서는 편목의 다양한 수준에 관해 논의하였다. 최소수준목록(Minimal level Cataloging)은 영미에서 연구가 시작되어 미의회도서관과 OCLC에서 표준으로 제정하여 사용하고있으며, 핵심수준목록을 대표하는 PCC(Program for Cooperative Cataloging)의 핵심레코드(Core record) 표준은 최근들어 모든 수준의 도서관에서 사용이 증가되고 있다. 이에 인터넷자원의 표현을 위한 더블린코어와 PCC 핵심레코드의 데이터요소를 비교하여 공통데이터요소와 비공통데이터요소를 도출하여 인터넷환경에서 새로운 핵심수준 서지기술 데이터요소를 제안하는 기초자료로 삼고자 하였다.

In this study, the appraisal in record continuum theory is analyzed in conjunction with the appraisal in life cycle model. In order to understand the more fundamental implications of appraisal in electronic record environment, it is essential to analyze the appraisal inherent in record continuum theory. Record continuum theory can provide a theoretical basis for appraisal in electronic record environment in that it is a theoretical system in opposition of the appraisal based on life cycle model and dualistic records management system resulting from it. In particular, considering that the appraisal is a purposive act of seeking the meaning of records, the reinterpretation of the concept and meaning of records intended in record continuum theory enables us to derive the different appraisal logics than before. Therefore In this study, based on comparison with the appraisal based on life cycle model and the new record concept presented in record continuum, the appraisal in record continuum theory is analyzed focusing on three aspects.

This study intends to make a comprehensive investigation on an application of FRBR model to KORMARC records. To the end, issues associated with FRBR implementation are analyzed, and automatic algorithms to covert bibliographic records into FRBR model are examined thoroughly. On the basis of it. this study implemented four-level hierarchical bibliographic structure of FRBR model using existing KORMARC records. 161 sample records for an experiment were selected from Korea national library. The work chosen as sample records was "Hamlet." Results suggest that considerable difficulties would be encountered in the process of FRBRizing KORMARC records.

Record continuum is a theory providing the basis for archival science in the paradigm shift to the electronic record environment. However, critical analysis of it has been hardly performed so far, as it is still in development, and its core is a new perspective on records different from the life cycle model. Therefore, for further understanding of the significance and limitations of record continuum in the electronic record environment and performance of more in-depth theoretical development, an analysis of the meaning and nature of records contained in record continuum logic is essential. Given that record continuum does not define a record separately, the meaning and nature of records it contains in the recent electronic record environment are examined through the analysis of axis and dimension in a record continuum model.

TLS 프로토콜은 인터넷 보안에서 가장 널리 사용되는 핵심 기술로서, 핸드쉐이크(handshake) 프로토콜과 레코드 레이어(record layer) 프로토콜로 구성된다. 핸드쉐이크에서 형성된 키를 이용하여 레코드 레이어 프로토콜에서 데이터들에 대해 인증, 무결성, 기밀성과 같은 정보보호 서비스를 제공한다. 이와 같이, TLS 프로토콜은 키 공유라고 하는 고전적인 암호학 문제를 포함하고 있기 때문에, 암호학 연구자들에게 접근성이 매우 뛰어난 연구 주제가 되어 왔다. 이를 반영하듯, 최근에 암호학 분야의 최고 권위 있는 Crypto학회에 TLS 이론 연구에 관한 논문이 연속적인 주제로 게재되었다. 본 논문에서는 최근 Crypto학회 및 eprint에 올라온 TLS와 관련된 최신 연구 동향 및 결과를 분석하여, TLS 프로토콜의 안전성을 연구하였다.

In this paper, the compatibility analysis on the track record operation center for the regional industry upbringing is presented. The renewable energy sources such as solar, wind and battery energy storage system have been widely spread in these days. Also the requirements on the efficiency, reliability and power demands of these distributed systems are increasing and they can be demands on the construction of the data track record center for renewable energy industries in order to promote the local industries. The analysis on the size of the de-centralized power system are performed based on the technical issues. The necessities, requirements and center goals to meet these missions are presented in the following session. The proposal of the 1 MW operation center construction and operations are presented in the result of the compatibility analysis. And the lists of the required equipments in the operation facilities are suggested to have proper operational capabilities. The results of this research can be applied in the fundamental data to promote the regional renewable industries.

This work provides new forensic techinque to a hide message on a directory index in Windows NTFS file system. Behavior characteristics of B-tree, which is apoted to manage an index entry, is utilized for hiding message in slack space of an index record. For hidden message not to be exposured, we use a disguised file in order not to be left in a file name attribute of a MFT entry. To understand of key idea of the proposed technique, we describe B-tree indexing method and the proposed of this work. We show the proposed technique is practical for anti-forensic usage with a real message hiding case using a developed software tool.

Both On-Line Analytical Processing (OLAF) data cubes and Statistical Databases (SDBs) deal with multidimensional data sets. and both are concerned with statistical summarizations over the dimensions of the data sets. However, there is a distinction between the two that can be made. While SDBs are usually derived from other base data, OLAF data cubes often represent directly the base data. In other word, the base data of SDBs are the macro-data, whereas the core cubiod data in OLAF data cubes are the micro-data. The base table in OLAF is used to populate the data cube with values of the measure attribute, and each record in the base tables is used to populate a cell of the core cuboid. The fact that OLAF data cubes mostly represent the micro-data may make some records be absent in the base table. Some cells of the core cuboid remain empty, if corresponding records are absent in the base table. Wang and others proposed a method for securing OLAF data cubes against privacy breaches. They assert that the proposed method does not depend on specific types of aggregation functions. In this paper, however, it is found that their assertion on aggregate functions is wrong whenever any cell of the core cuboid remains empty. The objective of this study is to design an inference control process in OLAF data cubes which rectifying Wang's error.

This study started from recognizing the problem that neither the identity nor the role of records managers is clarified enough. Therefore, this study identifies the function of the records managers and how it should be carried. The method of functional analysis was used to collect information, and then the AHP method to analyze te core functions of the records managers. As a result, core functions were identified as follows: records management policy making, education, production control, records schedule management, collecting, transferring, description, appraisal, de-accessioning, records center management, disclosure, perusal service, and records management system. Therefore, this study presents that identity and role of the records managers as well as the priorities of the job.
