The farming type in Korea is predominantly a small farm managed by family members. This study mainly examines the current usage of the website of family farms as a management tool for small farm business and discusses the strategies for effective utilization of the website. A county that currently employs governmental project of information system was purposely selected. Among all the websites operated by small farm businesses in that county, websites of which purpose is introduction of the business, advertisement, or e-business were included for analysis; it yielded total seven websites, The study was conducted with two phases; on-line website analysis and interview with business owners. The websites were analyzed based on four categories; content, interface, design, and site management. With regard to the content of the websites, the lack of connection between domain names and product names was found. Moreover, the problem relevant to site management was shown as low utilization of bulletin boards and delayed upload of new information. However, design and interface were comparatively well presented. Business owners reported that the motivation to initiate the websites was mostly supports from the governmental project for the agricultural information system. The barriers to effective management of websites were found i) business owner's misinterpretation of business website with e-business ii) very limited opportunity for website management education in small farm business, and iii) lack of regional infrastructure for information system. Based on the findings, this study suggests as followed; i) construction of infrastructure should be preceded to make effective management for websites; ii) education for website management should include small business management strategies as well as computer skills, iii) the education should be provided in diverse ways considering subject's characteristics iv) small farm business owners should be informed that their websites could play a role only to provide information about the products and hand over the practical load for e-business to retailing web sites such as portal shopping mall; and v) wives' participation should be encouraged.

In general, drivers need a self-interest information to decide their routes. So, non-governmental sectors, such as Internet Portal Company, make and provide user-oriented contents for drivers in a hurry. But, VMS which is the typical public media always provides traffic-information for drivers without weighting personal characteristics and considering transportation conditions. So in this research, we searched importance and preference of traffic-information contents as IPA(Importance-Performance Analysis)result. We can draw the conclusion that the improvement of traffic-information contents focused on users(drivers) is needed. Specially, we proposed the strategy of VMS according to traffic conditions.

The growth of blogs has two aspect of providing various information and marketing. This study collected the rankings of blog posts of large portal using OpenAPI and investigated the features of blogs ranked through the exploratory data analysis technique. As a result of the analysis, it was found that the influence of the blogger and the recent creation date of the post were highly influential factors in the top rank. Due to the weakness of these evaluation algorithms, there was a problem of showing the search results which is concentrated to the power blogger's post. In this study, we propose an algorithm that improves the reliability of content by adding the reliability DB information which is verified by the experts and reflects the fairness of the application of the ranking score through the trend index indicating various public interests. Improved algorithms have made it possible to provide more reliable information in the search results of the relevant field and have an effect of making it difficult to manipulate ranking by illegal applications that increase the number of visitors.

The aim of this study was to analyze the operation status of administrative information datasets of private universities and present improvement plans. For the system of private universities, the generation, correction, and deletion of functions, development types, and data were analyzed politically. As a result of the analysis, it has one or more administrative information systems and uses the academic management system in common, and the system is often developed on its own through the university's infrastructure, and data is deleted by the person in charge, but the regulations are not clear. To solve these problems, it was proposed to revise the EA portal to properly investigate the current status of the administrative information system of private universities, manage records centering on systems without data correction, and revise internal regulations to conduct education.

Currently, an implementation plan of administrative information dataset record management has been prepared; however, analyzing the specificity of various administrative information systems and preparing a reasonable level of management reference table by applying about 1.3% (EA portal registration system: 16,199, consulting system: 214) has its limitations. This study started by recognizing the importance of the records management environment in administrative information datasets. Based on the described information, the current records management environment was analyzed by dividing the six areas of the management reference table of the picture archiving and communication system (PACS) into three groups. Thus, a systematic environmental improvement model was proposed, enhancing the effectiveness of dataset records management in the field. Although there is a limitation in analyzing one of the dataset records management environments of various institutions, it is intended to help broaden the horizons of records management research.

The criterion which judges an information retrieval system performance is to how many accurately retrieve an information that the user wants. The search result which uses only homograph has been appears the various documents that relates to each meaning of the word or intensively appears the documents that relates to specific meaning of it. So in this paper, we suggest semantic information retrieval technique using relation within User-Word Intelligent Network(U-WIN) to solve a disambiguation of query In our experiment, queries divide into two classes, the homograph used in terminology and the general homograph, and it sets the expansion query forms at "query + hypemym". Thus we found that only web document search's precision is average 73.5% and integrated search's precision is average 70% in two portal site. It means that U-WIN-Based semantic information retrieval technique can be used efficiently for a IR system.

The customer loyalty has been decreasing dramatically in e-Business environments such as cyber trading, shopping, banking, and portal services. However, little research has been done so far in order to analysis the newly emerging concept and changing nature of the e-Business customer loyalty. The purpose of this study is to investigate whether the quality of e-Business information systems has any impact on customer loyalty. The quality, which is tee independent construct in this study, is divided into three variables: basic system quality, information contents quality, and service quality. Cyber systems of 40 domestic stock trading firms were chosen as target e-Business information systems Both online survey and traditional field survey were employed in order to collect data, and more than 8,000 cyber customers have responded. The results of statistical analysis show that all of three independent variables have statistically significant effects on customer loyalty and, among three variables, the basic system quality has the strongest impact.
