  • XML is recommended by W3C(World Wide Web) and widely accepted as a standard markup language for expression and sharing data. Recently, increasing the use and the amount of XML documents, there is required that easy methods for accessing XML documents at anytime and anywhere, therefore, the distributed XML repository systems is developed. For this, distributed XML repository systems is necessary to research catalog management schemes. In this paper, we design distributed XML database model considering CPU costs, I/O costs, concurrency control, two-phase commits a protocol, queuing delay and so on. And we implement a simulator in order to execute performance evaluation centralized catalog method, fully replicated catalog method, and partitioned catalog method using reasonably setting up environments.

  • It was analysed and considered about entry methods of headings in Japanese book cataloging which using methods of major universities and public libraries in our nation at present. I was suggested and clarified one's position that authors heading must make an entry to our pronunciation after translating from sound of chines letters, title headings must make an entry translation from Japanese title or Chinese title, to Korean. On the cataloging of authors heading or title heading, if cataloging make an entry to Japanese pronunciation it have many faults as follow. (1) In the title and authors heading of Japanese books, if it make an entry as Kana letter, not only non skilled librarian at Japanese language will have many faults but also non skilled users to Japanese language or pronunciation will very difficult to reference in title and authors catalog card. (2) If it Romanize the catalog card of title and authors heading in the Japanese books, librarian of the catalog part will make efforts and take pains to the catalog work. In addition, catalog users which is skilled in Japanese language but can not understand or unknown to the Romanized entry, and which if not understand to the, methods of entry will very difficult to card investigation or can not refer to catalog card. (3) If it make an entry to Korean in the authors and title heading from Japanese sound or pronunciation, librairans and library users which is unskilful as Japanese language will be inconvenience to works and investigation of library materials.

  • The KIER's Korean historical earthquake catalog was revised for MMI${\geq}$VI events recorded from the years 27 A.D. to 1904. the magnitude of each event was directly determined from the criteria suggested by Seo. The criteria incorporated the damage phenomena of the Japanese historical earthquake catalog, recent seismological studies, and the results of tests performed on ancient structures in Korea. Thus, the uncertainty of the magnitudes of the Korean historical earthquakes can be reduced. Also, the Gutenberg-Richter parameter values were estimated based on the revised catalog of this study. It was determined that the magnitudes of a maximum inland and minimum offshore event were approximately 6.3 and 6.5, respectively. The Gutenberg-Richter parameter pairs of the historical earthquake catalog were estimated to be a=5.32${\pm}$0.21, b=0.95${\pm}$0.19, which were somewhat lower than those obtained from recent complete instrumental earthquakes. No apparent change in the Gutenberg-Richter parameter is observed for the $16^{th}-17^{th}$ centuries of the seismically active period.

  • A clearly defined e-catalog (or product) information is a key foundation for an e-commerce system. A classification (or categorization) is a core information to build clear e-catalogs, can play an important role in quality of e-commerce systems using e-catalogs. However, as the wide use of online business transactions, the volume of e-catalog information that needs to be managed in a system has become drastically large, and the classification task of such data has become highly complex. In this paper, we present an e-catalog classifier system, and report on our effort to improve an e-catalog management process and to standardize e-catalogs for enterprises by use of automated approach for e-catalog classifier systems. Also we introduce some of the issues that we have experienced in the projects, so that our work may help those who do a similar project in the future.

  • This study is aimed at investigating and developing the use and sizing system of the apparels listed in on-line and catalog shopping in Korea. This is a basic study for an apparel sizing system to be developed, which could be used to approach consumers more easily and provide improved fitness and accuracy in terms of size and style of apparels for fashion E-commerce. A survey was conducted among the consumers who are more than 18-years-old and purchased more than two times the apparels listed in on-line and catalog shopping of two selected catalog shopping enterprises, and its statistical results are analysed from 281 respondents' questionnaires. The results of the study are as follows: 1. According to the result of the survey on the use and sizing system of the apparels listed in. on-line and catalog shopping, the consumers who purchased once apparels continue doing so in the same manner. A catalog shopping is the most preferred form of shopping. The most dissatisfying part in purchasing apparels is a poor quality of 'texture', and the second biggest problem is about 'size'About 51.2 percent of the apparels were not worn or even returned, while the top reason for that is 'Inappropriate size' and 'color', and 'texture'comes next on the list. 2. According to the survey on the recognition-rate concerning common' body size, most respondents were aware of their height and weight, and So percent of respondents said that they were aware of their waist circumference. But, chest circumference and hip circumference were recognized only by 58.4 percent and 35.6 percent of respondents, respectively. 3. According to the survey on difference between men and women, the male consumers have less aware of hip circumference than the female counterparts. The females have much more dissatisfaction with apparel sizing system and show higher return-rate of purchased apparels than the males.

  • We observed an area of 10 $deg^2$ of the Large Magellanic Cloud using the Infrared Camera (IRC) onboard AKARI. The observations were carried out using five imaging filters (3, 7, 11, 15, and $24{\mu}m$) and the prism disperser ($2-5{\mu}m$, ${\lambda}/{\Delta}{\lambda}{\sim}20$) equipped in the IRC. This paper presents an outline of the survey project and also describes very briefly the newly compiled near- to mid-infrared point source catalog. The $10{\sigma}$ limiting magnitudes are 17.9, 13.8, 12.4, 9.9, and 8.6 mag at 3.2, 7, 11, 15 and $24{\mu}m$, respectively. The photometric accuracy is estimated to be about 0.1 mag at $3.2{\mu}m$ and 0.06 - 0.07 mag in the other bands. The position accuracy is 0.3" at 3.2, 7 and $11{\mu}m$ and 1.0" at 15 and $24{\mu}m$. The sensitivities at 3.2, 7, and $24{\mu}m$ are roughly comparable to those of the Spitzer SAGE LMC point source catalog, while the AKARI catalog provides the data at 11 and $15{\mu}m$, covering the near- to mid-infrared spectral range continuously.

  • We introduce a coordinate catalog for photometry of the KMTNet Galactic bulge observation program and how to find the microlensing event candidates in the photometry result. Basically, the KMTNet bulge program is monitoring a total of 27 target fields (108 deg2) with four different cadences of 0.5, 1.0, 2.5, and 5.0 hours. In order to measure the stellar flux of each target, we made a 'observation coordinate catalog' by using the 'OGLE-III catalog' and 'DoPhot package'. The catalog contains approximately 0.3 billion stars in the bulge fields. We also search for a microlensing event candidates by means of the 'Event Finder algorithm' which calculates the restricted single-lens fitting (t0, teff, u0; u0 = 0 or 1) model. As a result, we found more than 2,000 microlensing event candidates per each year including about 700 events from the other survey groups such as OGLE and MOA. In this year, we will improve our current pipeline system, e.g. upgrading the catalog and applying real-time photometry.

  • There are two types of mold parts, ready-made standard parts and ETO (Engineered-to-Order) parts, the latter are of increasing importance to manufacturers. However, the ETO parts require more engineering support and communication than the ready-made standard parts. Existing e-Catalog modules provide classification structures of products that allow customers to select products based on their needs, and the trade begins with the provided specification. However, machine parts or mold parts have different purchasing patterns. Customers do not purchase the ready-made standard parts offered by an e-Catalog. They usually (1) add own options to the provided specifications or (2) change specification items such as length. To support these trades, a new e-Catalog system is proposed. The proposed system is based on the product design process and the specification selection process in addition to the parts classification structure.
