현재 대학은 온오프라인 경계가 무너지고 있다. 온라인을 통한 지식공유 활용이 활발해지고 정보기술의 발달에 따라 서서히 사이버대학으로 전환될 전망이다. 거기에 대학을 졸업한 인력들이 사이버대학으로 U턴하는 현상이 두드러지고 있다. 사이버대학의 가장 큰 장점은 시간과 공간에 구애 받지 않고 학습할 수 있다는 점이다. 하지만 사이버대학의 학습평가 방법은 많은 약점을 드러내고 있다. 본 논문에서는 사이버대학의 평가방법중 주관식유형의 평가시스템을 제안한다.

In recent years, the multilevel inverter synthesizing the output voltage with step pulse has been widely used rather than PWM method as a solution for high power and high voltage applications. This method takes advantage of lower switching losses due to one switching for one period. This paper proposes a simple method to obtain the conducting angle. This method is implemented by using voltage-second areas of the divided reference voltage according to the output voltage levels. It Is possible to reduce an amount of calculation because it is not required to solve the simultaneous equations by an iterative method. Also, the proposed method can get the conducting angle by means of on-line.

This study proposes a customized SNS operational strategy for special libraries based on a case study on the Ocean Science Library (OSL) of South Korea. The study conducted an in-depth analysis on an organizational structure, manpower, contents, and promotion. The outcome of SNS operational strategy deducted from this study can be categorized into several items, including: (1) a selection of an appropriate SNS channel, which meets the objective of the operation; (2) a formal division of works for SNS operation; (3) a designation of full-time managers and an establishment of a task force team; (4) a specialization of contents according to specific subjects; (5) on/off-line promotions focused on events, which encourage participations; (6) an improvement of contents through regular log analyses; and (7) a promotion of library website access through SNS, and so on. This research also suggested the strategies for the development of SNS operation: strengthening of communication and cooperation among librarians; distribution of academic and research outcomes of the umbrella organization; enhancement of a role as a communication channel between librarians and users, and carry out a role as a 'social curator.'

The purpose of this study is to elaborate the underlying mechanism by which information competency of those with disabilities influences their level of life satisfaction through a mediator, social capital built up through online and offline activities. To this end, the research conducts mediation analysis, comprised of three sets of regression by using the data of the "2018 Report on the Digital Divide." The results demonstrate that the information competency of those with disabilities has a significant effect on their level of life satisfaction; the higher the information competency, the greater the social capital. In addition, social capital partially mediates the relationship between information competency and life satisfaction. The policy implications from this study indicate that the efforts to improve information competency of those with disabilities should be made in a way that facilitates social interactions and community participation.

Stock information applications allow users to look up and find current stock information whenever and wherever. This study researched what kind of user experience the finance experts get when using these applications and what they suggest. The research was conducted through an in-depth interview of 8 finance experts, who worked minimum of three years, and used both Kakao Stock and JeungGwon Tong, the most used stock information applications, for a minimum duration of six months. The results show the user experience of Kakao Stock rated a bit higher than JeungGwon Tong. Since the objective of such applications are to show stock informations, the experts all rated the pleasurable and meaningful aspects rather low. They suggested, the developers should provide a more advanced and accurate information. They also suggested user interest recognized content be presented along with more convenient user interface to elevate usability. Hopefully, this study becomes a base to further study of user experience of various on and offline stock information services and they become a reference to develop a service with great user experience.

In ubiquitous environment, the analysis for student's learning behaviour is essential to provide students with personalized education. SCORM(Sharable Contents Object Reference Model), IMS LD (Instructional Management System Learning Design) standards provide the support function of learning design such as checking the progress. However, in case of applying these standards contain many problem to add or modify the contents. In this paper, We implement the system that manages the learner behaviour by hooking the event of web browser. Through all of this, HTML-based content can be recycled without any additional works and the problems by applying the standard can be improved because the store and analysis of the learning result is possible. It also supports the ubiquitous learning environment because of keeping track of the learning result in case of network disconnected.

The number of online video content distributors are rapidly increasing in N-screen environment. The purpose of this study is to analyze the business model of these distributors, especially Netflix and Hulu. Basis on STOF model, environmental domain, service domain, organization domain and financial domain of each company are analyzed and compared. This study finds that each company's business model had distinct characters in earlier stage. Netflix offered online and offline service in low cost, while Hulu offered up-to-date TV contents without fees. However, two companies' business models are getting similar. The result of this study shows that highly competitive environment and increasing content budget affect two companies to adopt similar business model to survive.

There are relatively inactive discussions about applying ubiquitous technology (uT) to traditional marketplace. If u-Market which affords to promote customer shopping convenience and on/offline shopping experience is implemented, then traffic of visiting customers as well as the revenue of the market will increase. Ultimately, it will lead to revitalizing traditional market. For this purpose, we developed a realistic u-Market service scenario with restricted uT considering spatial limitation and poor infrastructure of the physical marketplace. Based on u-Market service scenario, we have empirically investigated the determinants of u-Market service acceptance of the actual customers of traditional marketplace. We hope the results of this study will help in improvement of u-Market system development and service feasibility.
