The Donggungilgi (東宮日記) is the daily records of the Siganwon (侍講院), which was a royal office in the Joseon dynasty that took charge of the education for the crown prince who dwelled in the Donggung (East Palace). This literature contains records of meteorological and astronomical observations as well as educational matters. The Sohyeon-Donggungilgi (昭顯東宮日記) includes records from 1625 to 1645, when Prince Sohyeon, the first son of King Injo (仁祖), was the crown prince. We investigate the records of solar halo observations in the Sohyeon-Donggungilgi. For consistency, we restrict our investigation to the period before the second Manchu invasion of Korea (i.e., 1625 to 1635). We extract 2,684 records and classify them into ten events according to the terms in their descriptions. The largest and smallest number of observation records are for the Hun (暈) and Geuk (戟) events (1,794 and 7 records, respectively). To verify what each event represents in modern atmospheric terms, we refer to historical documents of the Seoungwanji (書雲觀志, Treaties on the Bureau of Astronomy) and Cheonmundaeseong (天文大成, Great Achievements in Astronomy). We also calculate the solar altitude based on the observation hour and compare the descriptions to compute simulations provided by Arbeitskreis Meteore e.V.. We find that the descriptions of the Hun, Junghun (重暈), Yi (珥), and Baekhonggwanil (白虹貫日) events indicate a 22˚ halo, 22˚ and 46˚ halos, a parhelion, and a parhelic circle, respectively, Alternatively, we estimate that the Gwan (冠), Dae (戴), Bae (背), Li (履), and Gyohun (交暈) events describe arcs tangent to a 22˚ or 46˚ halo such as a upper or lower tangent arc, a circumzenithal arc, or a parry arc. We suggest that further studies are required for the Geuk event because the descriptions of this event differ from both documents referred to this study. In the sense that the number of observation records of the Geuk event is the smallest, however, this event may describe a rare phenomenon. We believe that this work will contribute to the study of historical records of solar or lunar halos.

Traditional paper records have to be preserved in the original form to ensure the authenticity. On the other hand. electronic records have to be continuously changed in content itself or metadata to be preserved in long-term period, so the proof of the legality of each change made so far and the proof of the protection against all the illegal changes are the essential. to ensure these requirements. We need some functions including the authentication of original captured records. the protection of records against the loss or forgery, the authentication of preserved records, and the treatment of authentication-failed records. This paper explains the fragility of authenticity for electronic records, identifies the functions needed, suggests the implementation idea, and describes the overall management polity for electronic records to ensure the authenticity.

The school records are having lots of problems in the records management by the reason that general teachers who belongs to an elementary and a secondary school, were producing and managing all the records, they don't have any knowledge on the records management system. in this paper, tried to consider the plan of the school records classification scheme and record management system under the research on the actual condition of the management system and problem features. The first plan for managing is to complete the system of business classification scheme, the standardization of records management and develop manuals and guidelines, and the second is the range expansion of managing and reinforcing the appraisal procedures.

We study the correlation between distributions of astronomical records and historical events using historical meteor (shower) records. In Korean chronicles, planets and meteor (shower) records are the most abundant astronomical phenomena. And they represent a general tendency of the number distribution of whole astronomical observations. We examine the correlation for the number distribution between meteors (showers) and planets during A.D. 1200-1700 and find that both records have a similar distribution. We classify historical events into three grades according to the social impact, and investigate the correlation between distributions of meteor (shower) records with social events, such as, new king's accession to the throne, foreign invasions, and domestic turmoils. From the statistical analysis, we cannot find any correlation between the meteor (shower) records and the political events. Therefore, we conclude that Korean historical records have not been influenced by the political events. We also examine the correlation between Chinese and Japanese meteor (shower) records and political events for A.D. 1200-1700, respectively, but cannot find any correlations between them.

This study aims to analyze the current policies and problems associated with the electronic records disclosure and to suggest the access paradigm for electronic records management. For this, Act on Disclosure of Information by Public Agencies. Public Records Management Act, and Electronic Government Act are analyzed in the light of public access to electronic records. The analysis lays special emphasis on the scope of public records to be disclosed, time to disclosure of public records. computer editing for pubic service. records dissemination through Internet, and the role of records centers and public libraries. Based upon the analysis, policy directions for electronic records management are suggested.

This study investigates the importance of records management for local festivals by focusing on the Chunhyang Festival, one of Korea's oldest regional festival still in existence. This study analyzes the current conditions of records management to indicate problems and offer measures of importance. The results of this study showed the following problems. First, the absence of public-private partnerships and the lack of a stable commission. Second, the absence of ordinances for festival public records management. Third, the absence of systematic document management. Finally, absence of an expert records researcher and the absence of a records archive. Therefore, the study floated for an overall management method for the Chunhyang Festival records.

The purpose of the study is to examine the potentialities and limits of Business Reference Model (BRM) as records classification schemes in Korean central state institutions. The analysis is based on the data collected through focus group interviews of three times, in which six records professionals from central government agencies participate. This paper begins with inquiring the framework of records classification based BRM, required by Public Records Management Act. It explores the types of benefit of BRM application to government records classification. Based on the collected data from the interviews, it investigates how records are aggregated, and how transaction level (Danwi-Gwaje) of BRM is applied in the course of records aggregation.

Nowadays it is very necessary to generate artificial accelerograms because of lack of adequate earthquake records and vast usage of time-history dynamic analysis to calculate responses of structures. According to the lack of natural records, the best choice is to use proper artificial earthquake records for the specified design zone. These records should be generated in a way that would contain seismic properties of a vast area and therefore could be applied as design records. The main objective of this paper is to present a new method based on wavelet theory to generate more artificial earthquake records, which are compatible with target spectrum. Wavelets are able to decompose time series to several levels that each level covers a specific range of frequencies. If an accelerogram is transformed by Fourier transform to frequency domain, then wavelets are considered as a transform in time-scale domain which frequency has been changed to scale in the recent domain. Since wavelet theory separates each signal, it is able to generate so many artificial records having the same target spectrum.

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.

Traditional paper records have two aspects such that the paper records are information, and are information media itself. The preservation media for the paper records seems to be another forms for original ones including microfilm and optical disks. On the other hand, new-coming electronic records lack the aspect of information media. To guarantee the existency of the original electronic records we need the preservation media for the electronic records, different from the media for the traditional paper records. The preservation media helps the Authenticity, integrity, and usability as well. This paper describes the need for the preservation media, identifies problems on the existing concept for them, derives the principles to resolve the problems, and suggests the management policy based on the principles.
