This study looked at what factors lead to continuous participatory intention of online childrearing community. Trust, reciprocity and perceived security from the perspectives of community attributes and reputation motivation, information motivation, enjoyment motivation and self-monitoring from the users' perspectives were conceived as determinants that might have influences on continuous participatory intention of online childrearing community. It were also empirically tested whether they affect continuous participatory intention of online childrearing community. The moderating effect of self-monitoring was examined, too. In order to collect data, online questionnaires were conducted to women whose ages were 20-49 years old and joined online childrearing community. Their responses were analyzed with a regression analysis. The findings showed that trust, reciprocity and information motivation have influences on continuous participatory intention of online childrearing community. The moderating effect of self-monitoring between reciprocity and continuous participatory intention was also found.

전 세계적인 온라인 이용의 증가는 대학에서 학생들을 가르치던 전통적인 교수법에 커다를 변화를 가지고 있다. 학생들은 정보의 이용이나 과제의 제작, 제출에 있어, 사이버 공간을 적극 이용하고 있으며, 이미 거의 모든 고등교육기관에서 수강신청, 강의 평가나 성적 조회 등은 온라인을 통해 이루어지고 있다. 또한 오늘날의 변화된 소비자인 학생들에게는 온라인 강의보조자료가 학습에 더욱 효과적이라는 연구결과가 보고되고 있다. (중략)

본 연구의 목적은 온라인 학습자들의 학습효과를 높힐 수 있는 교수 학습환경을 마련하기 위한 기초자료를 제공하기 위함이다. 본 연구에서는 온라인 학습자들의 학습성취와 학습만족에 미치는 학습자 개인요인- 건강, 가족지원 정도, 컴퓨터 능력, 취업여부, 자기조절학습능력- 에 초점을 두어 분석하였다. 본 연구는 서울사이버대학교 사회복지학부 재학생을 대상으로 수집된 총 226개 설문지를 회귀분석방법으로 분석하였다. 연구결과 학습성취에는 학습자 개인의 건강, 자기조절학습능력이 유의미한 영향을 보였고, 학습만족에는 가족들의 지원 정도와 자기조절학습능력이 영향을 나타냈다.

The purpose of this study is to propose a new on-line nonlinear PCA(OL-NPCA) method for a nonlinear feature extraction from the incremental data. Kernel PCA(KPCA) is widely used for nonlinear feature extraction, however, it has been pointed out that KPCA has the following problems. First, applying KPCA to N patterns requires storing and finding the eigenvectors of a N${\times}$N kernel matrix, which is infeasible for a large number of data N. Second problem is that in order to update the eigenvectors with an another data, the whole eigenspace should be recomputed. OL-NPCA overcomes these problems by incremental eigenspace update method with a feature mapping function. According to the experimental results, which comes from applying OL-NPCA to a toy and a large data problem, OL-NPCA shows following advantages. First, OL-NPCA is more efficient in memory requirement than KPCA. Second advantage is that OL-NPCA is comparable in performance to KPCA. Furthermore, performance of OL-NPCA can be easily improved by re-learning the data.

In this paper, the results of previous studies and surveys conducted in this study were compared and analyzed to find out how the actual condition of distance learning being conducted due to COVID-19 is changing. As a result, it was found that the'content-oriented class' is being used the most in the current online class, and teachers are spending a lot of time preparing for class. In addition, it was found that' providing appropriate contents as learning materials' is the first item to be supported for online classes. Therefore, in order to improve online classes in the future, it is needed that learning materials that can be used to create class content should be provided to teachers sufficiently. Also, IT equipment and network expansion and the training of teachers for distance learning should be provided.

The purpose of this study is to investigate the relationship among SNS users' interpersonal trust, brand image and purchase intention. A total of 335 questionnaires were collected during 6 days by Embrain online research company. Collected data were analyzed by SPSSWIN and AMOS program and frequency analysis, confirmatory factor analysis, validity test, correlation analysis and structural equation model analysis were performed. The results of verifying the relationship among variables are as follows. First, SNS users' interpersonal trust in influencers had positively influenced by brand image. Second, brand image sold by influencers had positively influenced by purchase intention. Third, SNS users' interpersonal trust in influencers had a significant effect on purchase intention.

By the 1990s, Database Online Searching and CD-ROM Searching have been used universally in libraries. Due to their ease of use and facilitation, it is believed that such new media searching will produce more benefits than the usual printed materials. Furthermore, from the library management's point view, the new media searching's ability to minimize holding space will be another example of the advantage. The new media searching will have ever the printed materials. However, since it Is necessary to have an objective appraisal of the cost effectiveness in the implementation and the design of the new media system, it will be compared the new media searching with the conventional searching by using printed materials at the KIEP Library and Data Bank.

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.
