The Korean Library Association has developed the Korean Cataloging Rules, fourth edition(KCR4) in 2003 and the National Library of Korea developed integrated version of KORMARC formats in 2006 on the basis of KCR4. Many educational institutions and libraries are currently cataloging based on KORMARC. Nevertheless, we have encountered many problems on KCR4 and KORMARC formats which needed to be modified. This study is aimed at pointing out the problems of KCR4 in describing 245 field which has a crucial and important role. Therefore, this study proposes the improvement methods of the use of parenthesis and subfield code in 245 field, and presents a description format of volume number, statement of responsibility and joint works including more than four persons.

As external data have become important corporate information resources, there are growing needs to combine them with internal data. This paper proposes an ontology-based scheme to combine external data with multi-dimensional databases, which shall be called multi-dimensional event ontology. In the ontology, external data are represented as events. Event characteristics such as actors, places, times, targets are linked to dimensions of a multi-dimensional database. By mapping event characteristics to database dimensions, external event data are shared via multi-dimensional hierarchies. This paper proposes rules to synchronize information sharing in multi-dimensional event ontology such as upward event information sharing, downward event information sharing and complex event information sharing. These rules are implemented using Protege. This study has a value in suggesting Big Data information sharing processes using an event database framework.

A design method of fuzzy modeling is presented for the model identification of route choice of traffic problems.The proposed fuzzy modeling implements system structure and parameter identification in the eficient form of""IF..., THEN-.."", using the theories of optimization theory, linguistic fuzzy implication rules. Three kinds ofmethod for fuzzy modeling presented in this paper include simplified inference (type I), linear inference (type 21,and proposed modified-linear inference (type 3). The fuzzy inference method are utilized to develop the routechoice model in terms of accurate estimation and precise description of human travel behavior. In order to identifypremise structure and parameter of fuzzy implication rules, improved complex method is used and the least squaremethod is utilized for the identification of optimum consequence parameters. Data for route choice of trafficproblems are used to evaluate the performance of the proposed fuzzy modeling. The results show that the proposedmethod can produce the fuzzy model with higher accuracy than previous other studies -BL(binary logic) model,B(production system) model, FL(fuzzy logic) model, NN(neura1 network) model, and FNNs (fuzzy-neuralnetworks) model -.fuzzy-neural networks) model -.

To understand modern society, I think we should know both public records and corporate records. However, the business archives are in private sector for their great importance of current value. The corporates expect cost-benefit effect, management of the business archives are relatively inferior. In this article, I would study the archival management in the POSCO, a similar public corporation, through the archival theory and the research papers for the business archives management in the United States. I examined the POSCO's records category and management department to prescribe in the POSCO's related rules. And I map out organizational status of the POSCO Museum in the POSCO I examined activities of the POSCO's archives acquisition method about the records which left out the records management rules, unavoidably scattered and lost, or the records related the POSCO are created outer the corporation. I made up arrangement scheme of the archives with it and gave the code to mix the character and the figure. In accordance with the arrangement scheme of archives, I extracted the description elements of organizational structure and function and of real records. The former is guide level and the latter is in detail. The POSCO Museum used the business archives to publish the corporate history and to exhibit, but in another corporation, usage of the business archives was various, it is contacted current activities of the corporation. Through the case study, the archivist in the corporate archives developed the contemporary values to use the archives of the corporation. And I presented the potential of the POSCO's Museum to become corporate archives in the POSCO.

The purpose of this study is to explore business investment and operation of O2O (Online-To-Offline) combined service. The study will analyze the necessary factors for growing the business by dividing the O2O service by industry. The Online-to-Offline is a method of inducing purchases of products and services by connecting between online and offline This research methodology organized the four stages of the analysis process. The analysis of all stages was performed with association rules in big data techniques. It is divided into the start-up period, growth period, maturity period, and decline period, and analysis is conducted on the business investment, expenditure cost, business operation, and conflict factors. As the research result, the first analysis has shown commonality with government subsidies, bank loans, and personal funds in all industries. The second analysis showed a lot of expenditure on labor costs of internal employees, marketing/sales, facility facilities, equipment, and equipment purchase costs. The third analysis showed difficulty in raising the investment resources necessary for business operations in all industries. The last analysis showed conflicts in the industry, businesses license, legal systems, and small business owners in all industries. This study contributed to the abundance and diversity of research methodologies in management information systems using association rules. In addition, the description of organizational development theory was updated while explaining the business investment and operation of O2O combined services. In practical implication, the O2O services include environmental factors that cause convergence between industries. Accordingly, this is required for new O2O services through new laws and systems and reorganization of existing laws and regulations.

The cataloging rules of AACR families and bibliographic structure, which are broadly used in describing resources, show limitations in reflecting the unique bibliographic characteristics of Korean old materials. Thus this research proposed a bibliographic structure optimized to the unique bibliographic characteristics of Korean old materials by establishing bibliographic relationships between bibliographic entities based on the FRBR LRM conceptual model. The bibliographic relationships should be established in the way of connecting related materials in the bibliographic structure. These relationships should sufficiently reflect the bibliographic characteristics of the materials, physical variations, and content variations. Through this structure, the bibliographic description can be separated and integrated into the bibliograhpic unit by applying LRM conceptual model. By using the proposed structure, the organization, management, and utilization of Korean old materials can be more efficient. Also, it can provide a new bibliographic environment that can be the foundation of creating BIBFRAME records for Korean old materials.

When a human recognizes nouns in a sentence, s/he associates them with the hyper concepts of onus. For computer to simulate the human's word recognition, it should build the knowledge base (WordNet)for the hyper concepts of words. Until now, works for the WordNet haven't been performed in Korea, because they need lots of human efforts and time. But, as the power of computer is radically improved and common MRD becomes available, it is more feasible to automatically construct the WordNet. This paper proposes the method that automatically builds the WordNet of Korean nouns by using the descripti on of onus in Korean MRD, and it proposes the rules for extracting the hyper concepts (hypernyms)by analyzing structrual characteristics of Korean. The rules effect such characteristics as a headword lies on the rear part of sentences and the descriptive sentences of nouns have special structure. In addition, the WordNet prototype of Korean Nouns is developed, which is made by combining the hypernyms produced by the rules mentioned above. It extracts the hypernyms of about 2,500 sample words, and the result shows that about 92per cents of hypernyms are correct.

In the present work, FEM analyses are carried out to investigate the fractures occurred within the structural part in the course of combustion experiment. The loss of structural integrity stems from the localized deformation and the damage induced due to a severe change in the thermal load. Moreover, the two-back stress evolution model is proposed using the Armstrong-Frederick and the Phillips' rules to depict the plastic deformation, and the continuum damage mechanics is also incorporated into the present model. It is noted that the present model is able to formulate a wide range of constitutive description with ease. The numerical results depicts that a severe strain localization and damage evolution can be obtained depending on the dominant back stress.

This study is to investigate the level of understanding of the separation of dispensing and prescribing health policy in Korea and its associated factors. A questionnaire survey was conducted upon a sample of college students responded from 540, response rate 77.1%, 4 months after the introduction of the policy. The understanding level was measured using 4 question items describing the goal and motivation of the policy, and 8 items describing its operational rules. For each item, respondents were asked to mark whether the description was true or false. While the goal and motivation of the policy was relatively well informed (mean understanding score: 69.6 out of 100), the students did not have good understanding of the operational details of the policy (mean score: 32.5). The results of regression analyses showed that personal interest and agreement with the need of the policy were the most significant factors affecting the understanding level. It is suggested that, for other health policies in the future, policy makers in Korea need to develop more effective media communication strategies to inform general public of the practical details of the policy.
