  • In this research, it is proposed that a method to hide data by modifying directory index entry information. It consists of two methods: a directory list hiding and a file contents hiding. The directory list hiding method is to avoid the list of files from appearing in the file explorer window or the command prompt window. By modifying the file names of several index entries to make them duplicated, if the duplicated files are deleted, then the only the original file is deleted, but the modified files are retained in the MFT entry intact. So, the fact that these files are hidden is not exposed. The file contents hiding is to allocate data to be hidden on an empty index record page that is not used. If many files are made in the directory, several 4KB index records are allocated. NTFS leaves the empty index records unchanged after deleting the files. By modifying the run-list of the index record with the cluster number of the file-to-hide, the contents of the file-to-hide are hidden in the index record. By applying the proposed method to the case of hiding two files, the file lists are not exposed in the file explorer and the command prompt window, and the contents of the file-to-hide are hidden in the empty index record. It is proved that the proposed method has effectiveness and validity.

  • EDS is a typical convergence service performing convergence between functions owned by multiple SPs. EDS provides users with the relevant information and the communication by the various personal conditional environment. An alternative terminology for events for net- work related applications is 'triggers'-these are assumed to be included in the present description. Events could be defined as any activities which occur within a service avail ability, signals. Events can be managed, for example, as part of a context-aware application. EDS carry out a procedure for processing user's requested information about mobil network-based entities, such as the combination with various applications, such as a LBS (Location Based Service) and area information. In AS (Application Service) network environments, the user has his customized EDS in the network, the EDS automatically connects the appropriate Terminals consistent with a user profile. EDS can also send the collected information to other requesting users by way of event information and using the procedures of combination with other services. The user can record/retrieve the user-related information to from the information base through EDS.

  • An ontology is a complex structure dictionary that defines the relationship between terms and terms related to specific knowledge in a particular field. There have been attempts to construct various ontologies in Korea and abroad, but there has not been a case in which a large scale crime investigation record is constructed as an ontology and a service is implemented through the ontology. Therefore, this paper describes the process of constructing an ontology based on information extracted from instrusion theft field of unstructured data, a crime investigation document, and implementing an ontology-based search service and a crime spot recommendation service. In order to understand the performance of the search service, we have tested Top-K accuracy measurement, which is one of the accuracy measurement methods for event search, and obtained a maximum accuracy of 93.52% for the experimental data set. In addition, we have obtained a suitable clue field combination for the entire experimental data set, and we can calibrate the field location information in the database with the performance of F1-measure 76.19% Respectively.

  • The purpose of this study is to propose a record service based on the characteristics and production context of presidential records. To this end, we first looked at the design direction and characteristics of the e-jiwon system and then analyzed the structure and characteristics of records produced by the e-jiwon system. There are six types of records to be analyzed: e-jiwon document card, memo, schedule, diary, instruction card, and individual business system_speech DB. Next, through analysis of the Presidential Records Portal's records service, it was pointed out that the current records service does not fully reveal the production context and characteristics of records. Accordingly, as a service strategy based on the characteristics and context of presidential records, a service centered on each record card (e-jiwon document card, etc.) and a service that focuses on structural understanding of records and linkage between records were proposed.

  • This study aims to analyze the details of the executive order of the president of the United States, which have been developed in the country's administrative system to institutionalize the guarantee of the people's right to know the classified records, as well as to protecting national secrets. This study also aims to present any implications for the development of the classified record management system of Korea. To this end, the previously issued EO concerning the classified records management were reviewed in terms of its classification, safeguard, and declassification. The analysis results showed that the EO by the president established and prescribed the special access program for national secrets, the system to exempt and suspend the automatic declassification, and the sanctions for protecting national secrets. The EO also established and prescribed the appointment system for the person with the authority to classify record, automatic declassification program, and Mandatory declassification review system, as well as the procedures for historical researcher and certain former government personal to access the classified records with the purpose of guaranteeing people's right to know. As a result, this study identified implications for the development of Korea's classified record management system, as follows : First, it is necessary to restructure the current classified record management system, by changing the operations that is dependent on the director of the National Intelligence Service to the one that is dependent on the President. Second, it is necessary to legislate a separate special law for the classified record management system. Third, a standing supervisory body should be established for the integrated management and for the consistent and routine supervision of the classified record management. Fourth, it is necessary to establish procedures to further review the classification of classified record to correct the defects of the current classification system, which has been abused and mismanaged by the national agencies and organizations that produce classified record.

  • This study aims to analyze the frequency of keywords used in Korean abstracts, which are unstructured text data in the domestic record management research field, using text mining techniques to identify domestic record management research trends through distance analysis between keywords. To this end, 1,157 keywords of 77,578 journals were visualized by extracting 1,157 articles from 7 journal types (28 types) searched by major category (complex study) and middle category (literature informatics) from the institutional statistics (registered site, candidate site) of the Korean Citation Index (KCI). Analysis of t-Distributed Stochastic Neighbor Embedding (t-SNE) and Scattertext using Word2vec was performed. As a result of the analysis, first, it was confirmed that keywords such as "record management" (889 times), "analysis" (888 times), "archive" (742 times), "record" (562 times), and "utilization" (449 times) were treated as significant topics by researchers. Second, Word2vec analysis generated vector representations between keywords, and similarity distances were investigated and visualized using t-SNE and Scattertext. In the visualization results, the research area for record management was divided into two groups, with keywords such as "archiving," "national record management," "standardization," "official documents," and "record management systems" occurring frequently in the first group (past). On the other hand, keywords such as "community," "data," "record information service," "online," and "digital archives" in the second group (current) were garnering substantial focus.

  • The National Forest Seed and Variety Center aims to write a manual for cultivation and characteristic inspection of new seed varieties in Korea, serving dual purposes. The first is the enhancement of the test guidelines, particularly the distinctness, uniformity and stability (DUS) test, for new seed variety, where research and examination are conducted based on the test guidelines. However, if the crop-specific test guidelines are initially reorganized, the details are unclear. Therefore, it seeks to maintain a written record to prevent confusion when the person in charge is changed. The second is to encourage the development of new varieties. By incorporating general characteristics and cultivation techniques in the manual, it seeks to encourage breeders to develop new varieties. Additionally, it serves as an important chronological record of the creation process, thereby helping future manual authors. This article introduces the current status of new plant variety protection and outlines the significance of creating a manual for cultivation and characterization of Actinidia arguta for screening new varieties.

  • 전기통신 요금은 전기통신 사업자가 제공하는 서비스 이용에 대한 반대 급부로서 이용자가 지불하는 가격이라 정의할 수 있다. 전기통신 서비스에 대한 요금결정은 서비스 원가주의(Cost of service principle)와 서비스 가치주의(value of service principle)로 나눌수 있다. IP charging의 필요성은 크게 사용자 측면, 망사업자 측면, ISP을 고려 해야 할 것이다. ITU에서 IP Charging에 대한 관한 표준화연구를 시작한지 2년이 지난 오늘까지 뚜렷한 결과물이 제시되고 있지 않으므로 본 고는 일반적인 과금의 원칙 및 ATM과금 표준에서 제안한 과금요소를 예제로 하여 현재 ITU-T나 IPDR(IP Detail Record)의 표준화 동향을 살펴보고 IP 요금의 표준화방향에 대해 고려할 점을 논의하기로 한다.
