This study investigated how college students seek and use information sources in their everyday lives. A total of 360 students from twelve colleges located in Seoul were randomly selected and participated in this study. The survey asked them what kind of information sources they use in their everyday life and what differences it has when they seek the information sources for their decision making time. Various criteria for evaluating information sources were reviewed to adopt in this study and collected data were analyzed using SPSS 17.0.

The purpose of this study was to investigate the effects of Socioeconomic factors on medical information resources when medical consumer choose inpatient or outpatient services. The target population was 12,249 people aged above 19 in Chungcheongbuk-do. The sample was accrued for the period of 3 months in 2008 by face to face interview of direct visiting from systematic sampling method. There was a significant difference in the use of personal informer and public informer by sex(p<0.001). There was a significant difference in the use of experimental and professional informer by living area(p<0.001). In conclusion, the results suggest that there is relationship between medical information resource and socioeconomic factors of medical consumer.

The study examines two aspects that relate to undergraduates' selection and use of information sources for their academic assignments: (1) sources perceived useful vs. sources frequently used, and (2) source characteristics considered important as selection criteria vs. selection criteria used as reflected in characteristics of frequently used sources. A survey of 251 undergraduate students attempted to address the gaps between what students think they should do and what they actually do with regard to source selection. Characteristics of frequently used sources were analyzed to find out the criteria used for source selection. Friends/family were among the frequently used sources although they were not perceived as useful. Unlike other sources suffering gaps between the perceived usefulness and the use behavior, Web sources were the ones not only perceived most useful but also used most frequently. When the important selection criteria were compared with the characteristic of sources used often, students did not seem to actually use the selection criteria they thought important. While students considered some characteristics related to information quality (e.g., accuracy, comprehensiveness) as important criteria for source selection, the actual criteria they applied for choosing information sources could be described as 'convenient' or 'accessible' (e.g., efficient/time saving, easy to use, familiar, accessible). Based on the findings, suggestions were made to help bridge such gaps through information literacy programs and information systems design.

This study aims to look at overall adolescents' perceptions of library and reveal the relevance of search engine sources and library sources compared each elements of them and find out any related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine over library as their information search tool, and they used library as primarily a source of information for printed materials such as books and most of them don't use the library often. Also the result shows the population users tend to select information when it is easy to get and fast to access. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources- have significant differences each other.

본 연구에서는 사회학 분야 웹 정보원을 대상으로 동시링크분석을 실시하여 특정 학문분야의 지적구조를 분석하고, 검색엔진별 지적 구조의 차이를 분석함으로써 웹 정보원의 특성을 살펴보았다. 세 개의 검색엔진을 대상으로 지적구조의 차이를 비교한 결과, 웹 정보원 지도에서 전체적인 지적구조는 비슷하게 나타났지만, 몇 개의 웹 정보원의 경우에는 소속군집이 다르게 나타난 경우도 있었다. 그리고 Altavista와 AlltheWeb은 지도상의 웹 정보원 분포에 있어서 거의 유사한 구조를 보여주었다.

This research analyzed changes of the intellectual structure of web information by examining time changes and search engines using the co-links analysis. According to the results, the co-links web information clusters on the two maps appeared to contain changes in the intellectual structure over the two time periods. The intellectual structure that appeared in the information map for AltaVista and MSN Search engines was relatively similar. However. there were also cases where the clusters of some web information was different. The results of the research revealed that the cocitation analysis could be applied simultaneously to diachronous analysis in the web information.

We design the evaluation factors to represent the relevance distribution information between a query and sources and proposes the scheme to get relevance distribution information based on evaluation factors. Then it is developed that the organization is able to classify the best source toward query, and shown the algorithms that is able to select the best source toward users query, it is developed algorithms that is decided ranking and mering these, after choose the best source to evaluate a query, Finally, it merges the result from the source, and present them to the user to the issued query. This paper also develops the scheme to classify the best sources for query and presents the selection algorithm of the best information sources. Finally the ranking and merging Federated Retrieval System is presented.

This study identified types of information source, and explored a path model for consumer information search by shopping attributes in the context of online decision making. Participants completed self-administered questionnaires during regularly scheduled classes. A total of 219 usable questionnaires were obtained from respondents who enroll at universities in the southwestern region of the United States. For data analysis, factor analysis and path model estimation were used. Consumer information source was classified into three types for online clothing purchases: Online source, Offline retail source, and Mass media. Consumers were more likely to rely on offline retail source for online clothing purchases, than other sources. In consumer information search by shopping attributes, online sources were more likely to be related to transaction-related attributes(e.g., incentive service), whereas offline retail source(e.g., displays in stores, manufacturer's catalogs and pamphlets) were more likely to be related to product and market related attributes(e.g., aesthetics, price) when purchasing clothing online. Also, the path model emphasizes the effect of shopping attributes on traditional retailer search behavior, leading to online purchase intention for clothing. This study supports consumer information search by attributes, and discusses a managerial implication of multi-channel retailing for apparel.
