The purpose of this study is to evaluate the quality of the Serials Union Catalog(UCAT) of KISTI. In examining both MARC records and bibliographic display records of 172 Japanese serials, AACR2R and KORMARC formats were used as the standard rules. Those records were described in the minimum or incomplete level ; but had repeated errors in various data fields, which included the incorrect choice of main headings, parallel titles and other titles, the improper use of language codes and related data fields, and the provision of incomplete information, etc. To improve the overall quality of bibliographic database, thorough comprehension and application of cataloging rules and MARC formats are strongly required.

The active network is a new networking approach to allow new protocols to be developed easily by solving the limitation of the existing protocol development procedure and the long protocol standardization process. So far many research institutes and universities have proposed active node architectures and active packet formats, but still there are some problems needed to be solved. One of them is the active packet format and the routing approach which consider the requirements of various active applications. Therefore, in this paper, we figure cut the requirements of various active applications and design four types of active packet formats that reflect these requirements and propose routing schemes appropriate for these characteristics. Also we propose an active node architecture which reflect these requirements.

The need for reusing synthetic environment data that are employed in the field of modeling and simulation has recently been rising. SEDRIS (Synthetic Environment Data Representation & Interchange Specification) is a standard to exchange synthetic environment data, and is the specification utilized in various military simulations of the Pentagon for representing and exchanging 3D data. SEDRIS represents environmental areas based on a data model; it can represent wind speed, wind directions, weather changes, the information of buildings, as well as terrain data. In some situations, however, the synthetic environment data stored in SEDRIS format should be converted to various visualization formats. First, because SEDRIS is a form of a super-set, it is necessary to verify whether large scale SEDRIS files are stored successfully through visualization. Second, the synthetic environment data should be visualized in some visualization programs for the simulation results to provide an immersive and realistic sense. In this study, we have developed converters for converting SEDRIS data to various visualization formats and visualized the converted results.

Different CAD systems are used in ship outfitting design on different usage and purpose. Therefore, data exchanges between CAD systems are required from different formats. For data exchange, boundary representation standard formats such as IGES and ISO 10303 (STEP) are widely used. However, they present only B-rep representation. Because of different CAD systems have their own geometry format, data exchanges with design intend are difficult. Especially, Tribon and PDMS use primitives for express their geometry in ship outfitting design. However, Tribon primitives are represented their parameter by values that are non-parametric. Therefore, data size of catalogue library is bigger than different CAD system using parametric primitive representation. And that system has difficulty on data reprocessing. To solve that problem, we discuss about shape DB which contains design parameters of primitive for exchange Tribon primitives. And geometry data exchange between Tribon and Shape Database that defines based on PDMS scheme are specified using primitive mapping that can represent design intend.

Form the middle of 199os, most universities in Korea have requested their students to submit not only the original text books but also their Electronic Theses and Dissertations(ETD) for masters degree and doctorates degree. The ETD submitted by the students are usually developed by various kinds of word processors such as MS-Word, LaTex, and HWP. Since there is no standard format for ETD to merge various different formats yet, it is difficult to construct the integrated database that provides full-tex service. In this paper, we transform three different ETD formats into a unified one, construct a full-text database, and implement the full-text retrieval system for effective search in the Internet environment.

Gene Expression Omnibus (GEO) has kept the largest amount of gene-expression microarray data that have grown exponentially. Microarray data in GEO have been generated in many different formats and often lack standardized annotation and documentation. It is hard to know if preprocessing has been applied to a dataset or not and in what way. Standard-based integration of heterogeneous data formats and metadata is necessary for comprehensive data query, analysis and mining. We attempted to integrate the heterogeneous microarray data in GEO based on Minimum Information About a Microarray Experiment (MIAME) standard. We unified the data fields of GEO Data table and mapped the attributes of GEO metadata into MIAME elements. We also discriminated non-preprocessed raw datasets from others and processed ones by using a two-step classification method. Most of the procedures were developed as semi-automated algorithms with some degree of text mining techniques. We localized 2,967 Platforms, 4,867 Series and 103,590 Samples with covering 279 organisms, integrated them into a standard-based relational schema and developed a comprehensive query interface to extract. Our tool, GEOQuest is available at http://www.snubi.org/software/GEOQuest/.

The purpose of this paper is to investigate whether high-level(level 6) essay-writing questions in Test of Proficiency in Korean (TOPIK) have been presented appropriately so as to enable foreign test-takers to display their Korean writing ability properly, and to provide some suggestions on how those questions need to be changed. To accomplish this purpose, all the essay-writing questions were collected from the 33 TOPIK tests, from the 2nd in 1998 to the 35thin 2014, and analyzed from the perspectives of their topics and formats. The results are that high-level TOPIK essay-writing questions showed a strong tendency to take as their topics Korean sociocultural structures and phenomena, or current issues in Korea, and that they frequently employed guided writing formats by providing preset ideas or/and contexts for test-takers to write in a guided way; such tendencies were analyzed to shed a negative influence on test-takers displaying their writing ability and creativity, because those topics and preset ideas or contexts provided do not allow them to express their own opinions or positions freely. It is suggested that TOPIK essay-writing questions should be changed to deal with objective and general topics which enable test-takers to write freely and logically in Korean based on their experience, because TOPIK is not a test to check whether they have enough background knowledge about the Korean society and culture, but a test to assess their Korean proficiency.

The Digital Living Network Alliance (DLNA) specification enables sharing of multimedia contents in the home network. Ordinary users will assume multimedia compatibility among DLNA certified devices, but that is generally not the case. There are optional codecs and even proprietary codecs used by the manufacturers. Information on multimedia formats supported by the devices are in general not easily exposed, creating difficulties in media sharing and usage. In this paper, the contents directory information exchanges among DLNA devices over the network is analyzed, and a method for media compatibility analysis is provided, The user can get information on compatible media formats, enabling ease of DLNA system use.

This research is focused on an analysis on the structure of RAW image file and the development of a RAW image file viewer for an embedded device. Recently, several RAW image file formats are being used for saving and displaying the images created by various DSLR cameras, and the necessity of handing RAW images in mobile multimedia devices is increasing. For the development of RAW image decoding/encoding library applicable to WinCE-based embedded devices viewer, an analysis of RAW image file formats, such as CRW, CR2, PEF, NEF, MRW, have been performed because their formats are not released in public. By using the library, the analysis software which can extract RAW image data, 2~3 JPEG image files and other informations such as the specification of a camera and various photographic parameters from RAW image files, were developped and a RAW image file viewer which can run in WinCE-based embedded devices. The experimental result has shown that the viewer could encode and decode RAW image files successfully and it took approximately 10secs to load them to the screen in S3C6410 based embedded platform. The outcomes of this research cloud be a good information and solution to multimedia application developers.

Recently, cyber threats are frequently occurring in ICS(industrial control systems) of government agencies, infrastructure, and manufacturing companies. In order to cope with such cyber threats, it is necessary to apply CTI to ICS. For this purpose, a security information collection system is needed. However, it is difficult to install security solution in control devices such as PLC. Therefor, it is difficult to collect security information of ICS. In addition, there is a problem that the security information format generated in various assets is different. Therefore, in this paper, we propose an efficient method to collect ICS security information. We utilize CybOX/STIX/TAXII CTI models that are easy to apply to ICS. Using this model, we designed the formats to collect security information of ICS assets. We created formats for system logs, IDS logs, and EWS application logs of ICS assets using Windows and Linux. In addition, we designed and implemented a security information collection system that reflects the designed formats. This system can be used to apply monitoring system and CTI to future ICS.
