The traditional newspaper industry faces the opportunities and challenges of industry transformation and integration with new media. Consequently, the catalogs of newspapers and magazines are also updated. In this study, necessary information on catalogs was obtained and used to analyze the overall development trend of the newspaper industry. A word frequency analysis was then performed on the introduction and product categories of the catalogs, and the content and types of newspapers and magazines were examined. Furthermore, related factors such as price, number of pages, publishing frequency, and best-selling status were analyzed; the correlation among factors affecting best-selling status was also explored. Subsequently, each element and a combination of elements were used to generate a dataset, build three classification models, and analyze the accuracy of predictions of whether newspapers sold well under other circumstances. The experimental results showed that price is the most critical factor affecting the best-selling status of newspapers and magazines. Publishing frequency and the number of pages were also found to be significant indicators that impact people's subscription choices. Finally, a competitive strategy regarding content, price, quality, and positioning was developed.

E-Catalogs which describe products or services are one of the most important data for the electronic commerce. E-Catalogs are created, updated, and removed in order to keep up-to-date information in e-Catalog database. However, when the number of catalogs increases, information integrity is violated by the several reasons like catalog duplication and abnormal classification. Catalog search, duplication checking, and automatic classification are important functions to utilize e-Catalogs and keep the integrity of e-Catalog database. To implement these functions, probabilistic models that use statistics of index words extracted from e-Catalogs had been suggested and the feasibility of the methods had been shown in several papers. However, even though these functions are used together in the e-Catalog management system, there has not been enough consideration about how to share common data used for each function and how to effectively manage statistics of index words. In this paper, we suggest a method to implement these three functions by using simple SQL supported by relational database management system. In addition, we use materialized views to reduce the load for implementing an application that manages statistics of index words. This brings the efficiency of managing statistics of index words by putting database management systems optimize statistics updating. We showed that our method is feasible to implement three functions and effective to manage statistics of index words with empirical evaluation.

This study attempted at first to find out a more suitable form of catalog to guide library users who need subject approach through a literature survey, secondly to see how and which catalog form is kept by Korean research or special libraries through an analysing questionnaires, and thirdly to evaluate these data and explore the ways to improve the function of classified catalog in Korean research or special libraries. The findings of this study shows that a classified catalog is more desirable form of catalog in research or special libraries in Korea because of the diversity of languages of the literatures needed by researchers, the educational programs for librarians and the problems of subject heading lists. Above mentioned questionnaire survey shows that more than $70\%$ of research or special libraries in Korea uses classified catalogs. However, among those libraries - only $8\%$ has the index of cassified catalog which is prerequisite for the catalog users. This survey also indicates that recently many libraries began or converted classified catalogs to subject catalogs. The writer explains the beginnings or convertings of classified catalog to subject catalog is due to the fact that many libraries do not have the index of a classified catalog which is badly needed by the library users. Based on these findings, writer said that to improve the function of the present classified catalog, it should include it's index to guide the library users who are not familier with the classifing system of the subjects. Through the entire paper, the writer has attempted to develop a point of argument by comparing a classified catalog with a subject catalog. Writer's point is not only a subject catalog using the particular language terms as a communication tool has problems in itself, but also the prevailing of this catalog form in North America is caused by their different situations from ours.

The importance of users on library catalogs cannot be overemphasized. However little is verified about how well the users' needs have been met. The purpose of this research is to explore the characteristics and differences between user groups on library catalogs, and to draw implications for follow-up research. To the end, this research classified the users into four groups: elementary students, middle and high school students, college students, and the general public. Investigated are unique features and differences in searching behavior on library catalogs between the four groups. The data was collected through a survey with 544 users, and analyzed for both frequency test and Chi-square test. The major research results shows that there were statistically meaningful differences between the four groups. Also discussed are several suggestions for more in-depth research.

This study intends to make a comprehensive inquiry into the quality of subject data in library catalogs. On the basis of National Library Subject Headings (NLSH) developed in 2002, National Library of Korea (NLK) has input the subject data into cataloging records since 2003. However a serious question could arise regarding whether the data are appropriate and desirable as a subject of the work. Under these circumstances, this study examined as follows: First, the meanings and attributes of the 'subject' were examined with a comprehensive literature survey. Second, a experimental analysis was carried out to measure the quality of the subject data. Sample records were selected from NLK, LC and A university library in Korea, and absolute and relative quality were compared. Finally, the substantial and realistic strategies for improving the quality of subject data were discussed.

Electronic catalog contains ich semantics associated with products, and serves as a challenging practical domain for ontology application. Ontology is concerned with the nature and relations of being. It can play a crucial role in e-commerce as a formalization of e-Catalogs. Description Logics provide a theoretical core for most of the current ontology languages. In this paper, we present an ontological model of e-Catalogs in DL. We take an Extended Entity Relationship approach for conceptual modeling method, and present the fundamental set of modeling constructs and corresponding description language representation for each construct. Additional semantic knowledge can be represented directly in DL. Our modeling language stands within SHIQ(d) which is known reasonably practical with regard to its expressiveness and complexity. We illustrate sample scenarios to show how our approach may be utilized in modeling e-Catalogs, and also implement the scenarios through a DL inference tool to see the practical feasibility.

Structural control through seismic isolation using elastomeric rubber bearing, which is also known as High Damping Rubber Bearing (HDRB), has seen an increase in use to provide protective from earthquake, especially for new buildings in earthquake zones. Besides, HDRB has also been used in structural rehabilitation of older yet significant buildings, such as museums and palaces. However, the present design approach applied in normal practice has often resulted in dissimilar HDRB dimension requirement between structural designers and bearing manufacturers mainly due to ineffective communication. Therefore, in order to ease the design process, most HDRB manufacturers have come up with catalogs that list all necessary and relevant product lines specifically for structural engineers to choose from. In fact, these catalogs contain physical dimension, compression property, shear characteristic, and most importantly, the total rubber thickness. Nonetheless, other complicated issues, such as the relationship between target isolation period and displacement demand (which determines the total rubber thickness), are omitted due to cul-de-sac fixing of these values in the catalogs. As such, this paper presents a formula, which is derived and extended from the present design approach, in order to offer a simple guideline for engineers to estimate the required HDRB size. This improved design formula successfully minimizes the discrepancies stumbled upon among structural designers, builders, and rubber bearing manufacturers in terms of variation order issue at the designing stage because manufacturer of isolator is always the last to be appointed in most projects.

This study intends to make a comprehensive inquiry into the meaning and limitations of Folksonomy, and to explore how to make full use of Folksonomy in library cataloging. To this end, this study examined as follows : (1) how the philosophical meaning of Folksonomy is different from traditional principles of library cataloging, (2) what the viewpoint of LIS scholars toward Folksonomy are, and how North American libraries have customized Folksonomy for their catalogs. In addition, (3) usefulness of Folksonomy in library catalogs is thoroughly discussed. Based on these, (4) the final discussion includes strategies for Korean LIS scholars and library practitioners to consider when applying Folksonomy to Korea library contexts.
