Flash memory has been used by many digital devices for data storage, exploiting the advantages of non-volatility, low power, stability, and so on, with the help of high integrity, large capacity, and low price. As the fast growing popularity of flash memory, the density of it increases so significantly that its entire address mapping table becomes too big to be stored in SRAM. This paper proposes the associated page address cache with an efficient table management scheme for hybrid flash translation layer mapping. For this purpose, all tables are integrated into a map block containing entire physical page tables. Simulation results show that the proposed scheme can save the extra memory areas and decrease the searching time with less 2.5% of miss ratio on PC workload and can decrease the write overhead by performing write operation 33% out of total writes requested.

Web-based information resources should be managed and used methodically in the same manner as the paper-based resources are managed and used. It is necessitated by the prevalence of web-based delivery of a variety of information. To develop a web-based digital collection, it is critical to establish a set of standardized evaluation criteria for web-resources. The evaluation criteria needs to include authority, trustworthy, reliability, functionality, relatedness, accessibility, structure, design, user support, and security related matters. However, it is also necessary to have certain flexibility to either emphasize or include particular evaluation criteria to reflect varying characteristics of the web resources especially for the purpose of developing an effective digital collection. In addition, it is essential to review the evaluation criteria with respect to value, demand, duplication prevention, and intellectual property, which are relevant to the web-based digital collection development. Finally, various strategies were suggested as means to develop more effective web-based digital resource collection. These strategies include organizing a selection committee to ensure the objectivity and consistency in web-resource evaluation; developing a model for web-based digital resource collection; sharing new standards, protocols, markups, and metadata with other digital libraries; and developing user-centered digital resource collection.

Nowadays, as it goes on digitalization of the broadcasting and the convergence of the broadcasting and communications , it has been developed into the ubiquitous individual media consuming pattern which can easily and comfortably consume the favorite contents through any devices at anytime and/or anywhere. For this, in this paper, we propose personalized broadcasting service that can provide a convenient access of the contents that users want to watch at anytime by considering the user preference and consumption characteristics as well as an efficient browsing and watching of the particular program segments more advanced than the data broadcasting services. Moreover, it is implemented the TV-Anytime standard based on personalized broadcasting terminal platform by us. The developed services and terminal will used on broadcasting environment in which many services and the contents. The result of that is the broadcasters/service providers and content providers can provide differential broadcasting services which is suitable to each user such as personalized broadcasting service in near future.

It is important to improve TCP performance in Self-similar TCP network where signalling between the same end nodes through bidirectional traffic routes. In wireless link, the traffic limitation pattern occurred in two or more TCP connections is applied into MPEC video control as multi time-interval congestion control. For TCP update variable, we extend TCP and perform as function call, and we study a method of relating TCP with LTS module controlling with the information type that is overcoming the limit of feedback loop determined by RTT. For comparison, we measure the TCP throughput without LTS and verify the fairness by means of meta control. The improved TCP performance is shown by that the number of connections of traffic congestion control increases when RTT increases.

Previously, the International Council of Archives (ICA) provided the General International Standard Archival Description (ISAD(G)) and the International Standard Archival Authority Record for Corporate Bodies, Persons and Families (ISAAR(CPF)) for the systematic archival description by the Committee on Best Practice and Standards. Recently, the new conceptual model and ontology, which is called "Record in Context" (RIC), is being developed by the ICA Experts Group on Archival Description (EGAD). For developing the new archival standard, ICA EGAD has referenced the archival standards of Australia, Spain, and Finland, as well as the FRBRoo integrated model of the museum and library fields and the legacy ICA's descriptive standards. This study, therefore, examined these international trends on the archival descriptive standards and derived a number of suggestions for improvement. As a result, descriptive standards are changing from the guidelines for the standardized archival description to the upper conceptual model and ontology for the flexible archival description and sharing of archival metadata. There is a need to adapt the change of the information environment and promote cooperation among cultural heritage institutions.

Defense M&S software industry has carried out a variety of studies related to an efficient implementation of large-scale simulation and interoperability with respect to each of the system and HLA has been developed to provide a common architecture for distributed simulation of them. HLA defines Federate interface specification and provides services through RTI. Meanwhile, the difficulty lies in developing the software based HLA. Federate developer needs to understand how to handle Metadata produced RTI and has to modify the interface code whenever FDD is modified. This paper presents the implementation method of SOM interface using the code generation technique and middleware architecture for providing simple API. It solves the problem for implementing the framework of distributed object communication by using proposed method.

This study examined the factors that can enhance the continuity of user experience in multi - device environment. First of all, regarding the structural difference and continuity of tasks, functional differences such as OS difference according to the characteristics of cross media, use of mouse and touch gesture were found to interfere with continuity. To increase continuity, metaphor and ambience To increase relevance and visibility. In the continuity part of visual memory and cognition, familiarity was given by the identity and similarity of visual perception elements, and it was found that familiarity factors are closely related to continuity. Finally, for the continuity of the user experience, we can see that the visibility factors as well as the meaning and layout consistency of the information are factors for the continuity of the user experience. Based on this, it was found that familiarity, consistency, and correlation were significant influences on continuity dimension of user experience, but visibility did not have a significant effect on continuity when regression analysis was conducted as factors of familiarity, consistency, correlation and visibility.

The integrated management of community archives, which is conducted by incorporating them into the category of library data through the system of library materials management is more necessary for residents to use community archives by arranging and preserving them collected by public libraries, than management implemented through a separate system. This study therefore draw25 descriptive factors by comparatively analyzing descriptive factors of the descriptive standards for community archives such as ISAD(G) and DC, etc. and integrating common or similar ones. Such 25 drawn descriptive factors were empirically tested three times by professionals through the Delphi technique, and 3 descriptive sectors and 21 descriptive factors were finally drawn. The drawn descriptive factors were divided into mandatory, mandatory if applicable and optional through KORMARC-integrated format for bibliographic data and mapping and applied to the system of library materials management, by adjusting the descriptive factors for the systems.

With the enactment of regulations on confidential records management, the management of confidential records has become more important than ever. However, there remains no management method in the field of records management that takes the feature and values of confidential records into consideration. For this, this study processed electronically confidential records managed in a non-electronic environment. In addition, we developed a system that will allow public institutions to manage confidential records independently, that will prevent loss of information because of loss of or damage to the confidential records, and that can be used conveniently in the digital security environment of authorized users to establish a foundation for commercial management. In this study, we analyzed the system configuration requirements according to the international standard for the records management of a confidential records management system and system-related issues such as system design based on the analyzed requirements, system security and encryption, and metadata, the overall process of establishing and outputting secret management records and standard management.
