The Korean oldbooks that represent the spiritual product of the ancestors in the form of physical shape are absolute need for retrieval and new evaluation through research and discovery. To earn Korean oldbooks that have these values, catalogue of Korean oldbooks and annotation book were used as secondery materials. But since there haven't been publications of Korean oldbook catalogue that can be used as Korean oldbook search engine, Korean oldbooks that has same title was valued differently by the different authors and defined differently according to bibliographic study. And there even has been a case when, even though there is same edition it was consider the only one. Therefor it can cause a lot of mistakes when you can't over look totally. So you can expert better results in structuring DB with computer then publicized catalogue of Korean oldbooks. But at this present time, since all of the DB that have been structured are not unified as one system and operated separately in their organizations, there has been a problem like creating different bibliographic information for same Korean oldbooks. In this study, as one of the solution to the problems of searching Korean oldbooks, we are making a plan to develop the unified retrieval system of Korean oldbooks using hypertext system. And with these finding, we are suggesting the further way of developing retrieval system of Korean oldbooks.

전자해도 세부 속성정보 입력에 중요한 참고자료가 되는 전자해도 객체 카탈로그 입력지침(UOC)는 그동안 수정금지 되었으나, 최근 국제수로기구 기술 위원회의 협의를 거쳐 신규 버전을 개발하였으며, 이에 따라 전자해도 제작 시스템, 정보 입력자 및 ECDIS 제작자에 영향을 미칠 것으로 예상된다. 본 연구에서는 개정된 객체 카탈로그 입력지침을 분석하고 기존 문서와 비교를 통해 변경 내역을 파악하였으며 관련되는 시스템 및 담당자로의 영향 및 시사점을 도출 하였다.

The world faces a legacy of serious environmental problems such as exhaustion of natural resources and lack of landfill sites. To address these problems, recycling of materials and products has been proposed, but at present, it is realized only within a few fields. This is because most industrial products consist of various components made of different materials and their recycling are based on the assumption that they can be separated and classified easily, the actual situation however cannot satisfy this assumption. The issue in recycling the components and wastes of used cars, in turn, gives rise to emphasis on the disassembly process. For the efficient disassembly, the component materials and their easy separation as well as the recyclability must be taken into account as early as in the design process. It should be developed an almost perfect design catalogue with existing technologies by analyzing design characteristics, manufacturing, assembly and disassembly processes for major parts and components of automobiles in terms of existing and newly proposed recycling technologies. Also it is essential to provide more technical know-how and application methods that may be helpful to utilize different components and component groups.

For the commerce of sensual goods such as textile products, feel and touch is very important. Although on-line B2B commerce in textile materials are increasing currently, off-line sample exchange process is also required in order to make a decision. So far it is evident that the means of on-line communication is not sufficient to both customers and suppliers. The aim of this study is to improve the e-catalogues, which is the equivalent of showroom of off-line business, by analyzing information items offered in currently opened B2B sites and to categorize the essential information items to be included in the I-catalogues. The study was carried out as follows: First e-catalogues of many B2B sites were compared and analyzed from the viewpoint of customers, apparel manufacturers. Second, apparel manufacturers were interviewed to find out what causes the inconvenience, which prevent them to do B2B commerce. Third, on the basis of these n analysis, the researcher categorized information items of the e-catalogue. The apparel manufacturers were interviewed on the feasibility of the information items researcher suggested forth, With the results, we proposed an e-catalogue of 53 information items. Fifth, Another point of this study is that we tried to clarify the terminology for e-catalogue. Often textile traders and apparel manufacturers understand a same information with difference.

Outfitting systems in marine vessels have many kinds of standard parts. Ship CAD system should support the designers with an efficient tool for the modeling of outfitting parts such as pipes and valves. We develop a practical procedure for a part master model that combines ship CAD systems with the industrial standard. Part master or catalogue database of standard equipments is included in the database of ship CAD. The part master makes the associations of three dimensional modeling with the industrial standard. Moreover, it reflects the automatic modeling to maintain attributes that are disclosed in the entity of each part master in order to reduce the modeling time. Entity and attributes of pipe and valves are chosen from JIS(Japanese Industrial Standards) in order to explain the proposed procedure. Suggested procedure explains that three dimensional model of equipment is generated by parsing the pre-defined attributes after the entities of part masters is stored in database.

It is a long known fact that there exists a tight correlation between far-infrared and radio emission both for galaxies hosting active galactic nuclei and for star forming galaxies. We probe the radio - infrared correlation for a sample of extragalactic sources constructed by the cross-correlation of the AKARI/IRC All-Sky Survey Point Source Catalogue, the AKARI/FIS All-Sky Survey Bright Source Catalogue, and the NRAO VLA Sky Survey. Additionally, all objects of our sample were identified as galaxies in NED and SIMBAD databases, and a part of them is known to host active galactic nuclei (AGNs). After remeasuring all the fluxes, in order to avoid small aperture effects, we compare the ratio of radio to infrared emission from different types of extragalactic sources, and discuss the FIR/radio correlation as seen by AKARI and make a comparison to the previous results obtained thanks to IRAS.

For F,G,K stars, their photometric data and metallicity, [Fe/H] are collected and their correlations between $\delta$(U-B) and [Fe/H] for each spectral group are examined, using a reference sequence which is defined by the stars in Woolley's catalogue and other reference sequences. Detailed examination shows that the reference sequence by Woolley's catalogue appears to be properly defined for the calculation of $\delta$(U-B) of population I stars in the solar neighborhood. It is suggested that accuracies of metallicities derived from $\delta$(U-B) can be improved if we derive the correlations between [Fe/H] and $\delta$(U-B) from the stars in each spectral group.

The point sources in the Bright Source Catalogue of the AKARI Far-Infrared Surveyor (FIS) were classified based on their FIR and mid-IR fluxes and colours into young stellar object (YSO) and extragalactic source types using a Quadratic Discriminant Analysis method (QDA) and Support Vector Machines (SVM). The reliability of the selection of YSO candidates is high, and the number of known YSO candidates were increased significantly, that we demonstrate in the case of the nearby open cluster IC348. Our results show that we can separate galactic and extragalactic AKARI point sources in the multidimensioal space of FIR fluxes and colours with high reliability, however, differentiating among the extragalactic sub-types needs further information.

Properties of ULIRGs (Ultra Luminous InfraRed Galaxies) are important to understand the cosmic star formation history. To investigate their properties up to z=0.3, we search for ULIRGs identified by using the AKARI/FIS Bright Source Catalogue and the WISE All-Sky catalog. By matching the AKARI $90{\mu}m$ catalogue with the WISE catalog, we selected 3,452 galaxies. Additionally, combined with the SDSS DR10 spectroscopic data, we selected 952 galaxies with spec-z. We then computed total infrared luminosities using SED fitting technique, and identified 31 ULIRGs, 561 LIRGs and 344 IRGs. For these galaxies, we found an indication that ULIRGs selected by AKARI change the SED shape with redshift (z = 0.1 - 0.3).
