교수-학습과정에서 학습자가 가지고 있는 학습 장애는 학습 결과에 많은 영향을 미친다. 학습자의 학습 장애를 정확하게 진단하고 이를 고려한 수업 활동이 전개되어야 효과적인 교수-학습 활동이 이루어 질 수 있다. 학습 장애의 특성상 장애 진단과 처방과정에서는 비공개적인 접근이 요구된다. 인터넷 기반의 온라인 학습 장애 진단과 처방시스템은 이와 같은 문제를 해결할 수 있는 유용한 방안 중의 하나가 될 것이다. 하지만 기 구축되어 운영 중인 온라인 기반 학습 장애 관련 사이트들은 학습 장애를 진단해 주고 처방해 주기 보다는 학습 장애 정보를 안내해 주는 정도의 수준에 에 그치고 있다. 단순히 웹문서 형태의 정보제공 체제이거나 텍스트 기반의 지식 전달 체계로 인하여 학습자 개개인의 특성을 고려한 장애 진단에 한계점을 가지고 있다. 학습 장애에 대한 지식을 체계화함과 동시에 일정한 기준에 의해 연관성을 지어 줄 수 있는 의미 분석과 추론 등의 방법에 사용되어지는 온톨로지를 활용하게 되면 기존의 시스템이 가지는 제한점들을 극복할 수 있을 것이다. 이에 본 연구에서는 온라인 상황에서 학습자의 학습 장애를 정확하게 진단하기 위해 온톨로지를 이용하여 학습장애 진단 시스템을 설계하고 구현하였다. 온톨로지의 구축에 사용된 도구는 protege-2000을 사용하였다. 진단시스템 개발 환경으로 학습자의 인터페이스는 Visual C++, 교사의 인터페이스는 Visual Studio.NET을 사용하였으며, DBMS는 Microsoft Office Access와 MS-SQL Server를 사용하였다. 이 연구는 OWL 온톨로지를 사용하여 보다 지능화된 학습 장애 진단시스템을 개발함으로써 실현 가능성을 제안하고 있는 것이 연구의 의의이다.

In this paper, we proposed the methodology for analyzing online customer reviews by using text mining technologies. We introduced marketing segmentation into the methodology because it would be efficient and effective to analyze the online customers by grouping them into similar online customers that might include similar opinions and experiences of the customers. That is, the methodology uses categorization and information extraction functions among text mining technologies, matched up with the concept of market segmentation. In particular, the methodology also uses cross-tabulations analysis function which is a kind of traditional statistics analysis functions to derive rigorous results of the analysis. In order to confirm the validity of the methodology, we actually analyzed online customer reviews related with tourism by using the methodology.

블로그는 현재 광범위하게 대중성을 얻고 있는 온라인 커뮤니케이션의 최근 형태이며, 블로그 사용이 빠른 속도로 주류를 형성해 나가고 있다. 초기 HCI 분야에서의 온라인 커뮤니케이션(CMC)에 대한 연구는 사용자가 시스템의 소프트웨어나 하드웨어의 인터페이스를 어떻게 대하는가 하는 점에 초점이 맞춰졌었지만, 최근에는 온라인 커뮤니티, 블로그처럼 사용자들이 인터넷을 통한 사회화가 어느 때보다 활발하게 이루어지고 있기 때문에, 시스템의 사용성에 대한 고려만으로는 충분하지가 않다. 즉, 시스템이 어떻게 사용자들 간에 사회적 상호 교류를 지원할 수 있고, 이러한 사회적 교류가 원활하게 이루어지기 위해서 시스템이 어떻게 설계되어야 하는 지에 대한 이해가 필요하다. 따라서 본 연구에서는 실제 블로그 이용자들을 대상으로 이들과 상호 연결된 블로거들과의 온라인에서의 관계적 행위를 살펴보고, 또한 이러한 행위가 네트워크 구조적 특성과는 어떠한 상관 관계를 가지는지를 심층 인터뷰와 사회 네트워크 분석법을 이용하여 탐색적으로 알아보고자 한다. 본 연구 결과를 통해서 얻은 사용자들의 온라인 교류 시 보이는 행위적 특성을 바탕으로 온라인 개인 미디어 서비스 설계에 대한 가이드라인을 제안해 보고자 한다.

In this study, we have developed an online learning community site using Humhub social network software and promote social constructive learning through the questions and answers in subject specific learning groups. By accumulating learning contents which consist of questions and answers about specific topics, learners can acquire knowledge by searching relevant topics and questions and can create and reconstruct knowledge as well as consuming knowledge by participating in self-regulated learning community. We have developed a mathematical editor feature which enables users to enter mathematical expression such as equations and greek characters. Online learning community sites can be used for inquiry based information education.

With the rapid growth of recent smart phone technology, the interests for the design of online game in mobile computing environment are highly focussed on with great attention. Smart phone as a mobile terminal device, however, has many restrictions for implementing online mobile game since the limitation of relatively low performance of a processor, low resolution of GUI, small memory spaces, and short battery power. Therefore, most of games are very restricted on online and multi-play functions. In this paper, we design and implement mobile online game app in component based smart phone environment in order to take over these restrictions in mobile environment. Especially, the implemented mobile game is able to play online game among Wi-Fi based game server and another smart phone.

Purpose: This study aims to understand the online practice experience of nursing students through virtual simulation in order to prepare basic data for online practice program development. Methods: This study is a descriptive study that applied a qualitative thematic analysis method to explore the online practice experiences of nursing students. It was targeted to 16 students in the department of nursing at a university. Results: As a result, 5 themes such as 'Feeling ambivalent about the online practice', 'Doubts about the effectiveness of online practice', 'Running into the limits of online practice', 'Feeling like a virtual simulation as an alternative', and 'Approaching true nursing' Conclusion: Virtual simulation is considered a very effective online practice program. However, since the lack of various scenarios and cases is pointed out as a limitation, it is necessary to develop and apply more diverse and systematic practice programs in future research.

This study was conducted for nursing students to identify the effects of professors' teaching skills, learners' online learning readiness and major satisfaction on the online learning satisfaction after the COVID-19 pandemic. The participants recruited from nursing colleges located in five province, and data was collected using the Google Online Questionnaire from August 17th to October 5th, 2020. A total of 130 data were analyzed using the SPSS 23.0 program. As a result of this study, the factors that affect online learning satisfaction are the methods in the teaching skills (β=.43, p <.001) and self-directed learning in the online learning readiness (β=.33, p <.001), and satisfaction in nursing major (β=.21, p <.001). The results of this study suggest that education methods need to be devised to enhance the satisfaction of online learning in nursing colleges, and environmental improvements that can be self-directed learning are needed.

A counterfeit product is a product that pretends to be a genuine product by pretending to be false. It can also be called a counterfeit product. This study attempts to investigate how such illegal floods of counterfeit goods affect online shopping consumers. In addition, the accessibility of various product reviews on the internet is increasing, and the product reviews are divided into positive and negative reviews, affecting the information that the customer has already, and the influence of the information acceptance on the purchase intention depending on the product involvement Respectively. Therefore, the focus of this study was to examine whether the information presentation about counterfeit products affects consumers' purchase intention, review direction (positive / negative), and involvement (high / low) control the information about counterfeit products. Therefore, this study has shown that it provides a marketing strategy to increase the intention to purchase products and products in online companies and stores in a situation where information about counterfeits is exposed to online consumers in China market.

This study is an empirical analysis on the relationship between social presence and online community users' continuance intention. Based on Bhattacherjee(2001)'s expectation-confirmation model (ECM) of IT continuance model, we test the influence of social presence on one's intention to continue using online communities. This study sampled 132 online community users. Research hypotheses are tested using the structural equation modelling(SEM) approach. The results of this study demonstrate that user satisfaction is influenced by perceived usefulness and perceived enjoyment. But, the confirmation of expectation did not affect user satisfaction. And, social presence has direct effects on perceived usefulness and perceived enjoyment. Further, social presence has a positive effect on users' continuance intention through mediating effect of perceived usefulness. This study suggests that perceived usefulness should be taken into account when carrying out the operating strategy of online communities.

This study aims to examine online students' informal information seeking behavior during their loaming process and online loaming environments to support their informal information needs. The participants of the study were 29 online students in the Professional Development Studies of Rutgers University. Data was collected by the questionnaire and was analyzed with content analysis and descriptive statistics. This study focuses on when and why online students need human interaction to solve their learning problems and how they communicate with others to meet their informal information needs. Moreover, how online students think about their personal communication opportunities and the functions of their online learning system to support their loaming problems is also examined. Finally, online students suggest the ways to effectively support personal communication needed during learning process in online teaming systems. Based on the findings of this study, a few considerations are suggested in conclusions.
