Several seismic traces of earthquakes observed from the digital new type seismograph instruments of KMA in 2000 were scanned. From these, good quality data which have high signal/noise ratio were selected and they were transformed into ascii data from binary data(min-seed format). The hypo71 program and P-S was applied in order to determine the location of epicenter, origin time and the magnitude. From these data, the 29 earthquakes, 358 seismic records consist of 587 directional components were calculated. Using these, ground acceleration data, acceleration, velocity, and displacemnet response spectrums of the structures were calculated and they could be represented in a picture by the form of tripartite response spectrum. In the result, response spectrums of the 587 directional components of the above seismic data records were obtained respectively.

Although digitization contributes to the conservation and preservation of cultural heritage resources, detailing the necessary techniques is a lack of standardization in existing digital repositories. The purpose of this paper is to present practical strategies to illustrate technical details of imaging processes and metadata description with examples. This paper also provides important management issues related to digitization management for project managers and practitioners.

전자보존이라는 것은 한 기관이나 한 분야, 한 국가에 국한된 문제가 아니라 이 분야에 있는 사람이면 누구나 다루어야할 세계적인 규모의 쟁점이 되고 있다. 비록 많은 연구들이 행해지고 있지만 실제적이고 불후의 해결책은 아직도 마련되지 못하고 있는 실정이다. 보존을 위한 필요조건은 전자정보의 접근성과 이용가능성을 기본으로 하고, 문서에서 장기보존에 관련된 기준은 문서생산기관에서 문서시스템의 설계단계에서 이미 고려되어져야 한다. 문서가 어디서 관리되어지느냐에 따라 문서시스템이나 업무시스템에 통합되어져야 한다. 전자문서보존과 관리를 위한 적절한 환경을 만들려면 전자정부와 전자서비스전달과 관련된 개발이 필요하고, 이를 위해 기관은 현재 봉하고 있는 인프라를 기술적이고 체계적으로 평가하여 완전히 재구축 하여야 한다.

This paper suggests efficient policies of the long term preservation and digital archiving of Korean electronic journals based on the OAIS Reference Model. For this purpose, a questionnaire survey and interviews have been conducted to the institutions which are providing access to Korean electronic journals. Information packages and functional workflows which suggested in the OAIS Reference Model are applied to improve the long term preservation.

South Korean species of the genus Teleutaea is taxonomically studied. This genus is recorded from South Korea for the first time with eight species, Teleutaea acarinata, T. brischkei, T. diminuta, T. minamikawai, T. mishae, T. nigra, T. orientalis and T. ussuriensis. A key to eight South Korean species of Teleutaea and digital images are provided.

As a result of growth of digital music market in Korea, Creator's rights and interests have been at the heart of the debate in terms of legal system. In the music industry, digital music revenue has now overtaken records sales and compared to download service it is now clear that music streaming and subscription is mainstream model in the rise of the worldwide market of digital music. This trend is also indentical to the domestic and withholding regulations for music service and creator's rights and interests have become an ever growing issue. Ministry of Culture, Sports ad Tourism decided the revision of withholding regulations for the digital music service in 2013. The amendment is to change its policy of charging music service from the flat rate pricing to a usage-based system. This paper brought forward some disputable points such as fair division of profit, reasonable pricing for consumers etc. about the revision. Therefore, improvement of system and change in the perception of such copyrights are still required for both the encouragement of creator's activities and the high consumer satisfaction.

This paper propose the "Digital Format Registry(DFR)" to solve the problem related digital objects preservation system in the Korean Industry. Digital format registry is a kind of database that saves syntax and meaning informations of a digital file format and for giving help to make preserve in long-term even technical environment of a specific application has been changing. The role of the Technical Information Registry has been developed in this research and development is maintaining a technical information that is the foundation to maintain the long-term preservation and access to a digital objects. The function that can extract text information from a digital document object is implemented in DFR as a basic function at the first time in the world. This function make information consumers search a information that is needed easily and conveniently and can be used for development more effective records management system with retrieving the Key(index).

In this paper, we introduce the performance test results of digital data processing system for KVN (Korean VLBI Network). The digital data processing system for KVN consists of DAS (Data Acquisition System) and high-speed recorder which called Mark5B system. DAS system performs the digitalization of analog radio signal through ADS-1000 gigabit sampler with 1 Gsps/2-bit and process the digital filtering of digital signal. Mark5B system records the output data of DFB (Digital Filter Bank) with about 1 Gbps. In this paper, we carried out the preliminary evaluation experiments of the KVN digital data processing system connected between DAS system and Mark5B with VSI (VLBI Standard Interface) interface which is designed for compatible in each VLBI system. We first performed all of the KVN digital data processing system connected by VSI interface in the world. In factory inspection phase, we found that the DAS system has a memory read/write error in DSM (Digital Spectrometer) by analyzing the recorded data in Mark5B system. We confirmed that the DSM memory error has been correctly solved by comparing DSM results with Mark5B results. The effectiveness of KVN digital data processing system has been verified through the preliminary experiments such as data transmission, recording with VSI interface connection and data analysis between DSM and Mark5B system. In future work, we will perform the real astronomical observation by using the KVN 21m radio telescopes so as to verify its stability and performance.

Tools are needed to have access to more effective information and to select it in the environment of digital information where information pours in. and some of the advanced techniques to make up these tools are metadata and annotation. Annotation additionally records the marks for the supplementary explanation of and emphasis on a specific part of the original text and kas more various merits than metadata in terms of the search and use of digital resources. This research aims at suggesting methods that annotation. which has a range of functions including access to information. its reuse and sharing in the digital surroundings of late, can be applied to digital contents such as web services, digital libraries and electronic books. As to the research method, the case studies of annotation systems applied to web services and digital libraries have been carried out, and the metadata formation of the systems has been analyzed.

OAIS Reference Model has become a basis for exchanging ideas and cooperating among institutions and various sectors concerned with digital archiving. It has been also recently approved as a new ISO standard. This paper reviews major concepts and issues that the reference addresses. It also introduces current activities of institutions and projects that have contributed to the development process of the model. Conclusion is devoted to address the importance of cooperation among cultural institutions. These institutions are taking the responsibility of preserving digital information for the long-term as authentic as possible and delivering it to the next generation.
