Due tothe popularity of personal web-casting 'Food Web Casting' program, the present study aims to examine its effects on real life. The study conducted a survey with Korean college students. Results from a survey of 256 participants showed that first, the most salient reason for watching 'Food Web Casting' was gratification for killing time and gratifications for food entertainment, information, vicarious, and para social interaction are followed. Second, vicarious gratification, killing time gratification, and vicarious gourmandism gratification had a positive effect on Food Wed Casting programs viewing time, while it is not found for effects of gratifications for information and pro-social interaction. Third, it is found that Food Wed Casting programs viewing had effects on viewing happiness and negative perception of fat people. However, it did not have an effect on frequency of food delivery service. Based on these findings,implication, limitations, and topics for future research are discussed.

An increasing number of people in their lifes have used personal web-casting services as a new type of broadcasting, whose power has grown in the broadcasting market and industry. Nevertheless, limited research concerning personal web-casting has been conducted so far. This research explored consumption structures of personal web-casting users in terms of their genre usage based on the theoretical concept of genre repertoire. And it also examined what determinants have influences on these structures by focusing on as an representative case in South Korea. The findings showed that sensation seeking, motivation for getting information and social presence affect genre repertoire of personal web-casting users. They also indicated that there is a moderating effect of social presence in the relationship between motivation for joy and genre repertoire.

Recently, web casting on the internet has been expanding in number and size. Web Casting is different from the conventional television broadcasting since it can transmit various types of information through multimedia and it also can include interaction between users and broadcasting server. User experience by interaction becomes more important. Therefore, it is needed to win over customers by supplying satisfied experience through creative and different services, especially when there are consider competitions among music casting sites. In order to know how to make customers satisfied, we have to try to inspect what real customers in the Web Sites are acting and thinking, namely 'customer experience'. The 'customer experience' means every experience what users are expecting, doing, thinking and feeling when they stay in the Web site and online. In this thesis, the evaluation Guideline for music casting websites is developed by understanding customer experience on the music casting websites. The process of understanding customer experience was implemented through user observation methods, such as web Diary, group interview, and questionnaire. As a result of the study, 67 evaluation Guidelines with weight rate in 6 categories which are searching music, listening music, music video, music broadcasting, music mailing and other contents are developed. It can be used to analyze strengths and weakness of music casting sites and to establish business strategy for the more satisfied customer experience.

Web casting has become an important opportunity to apply the user-centered concept to broadcasting because it provides real-time interactive service through time and space. It is also necessary to have a new understanding about user who is not a passive viewer any more but an active user. The amount and quality of contents are also important, but usability is a competitive factor as well as the fundamental customer services that have user best experience at the site. Nevertheless most of web casting sites show the low level of usability. In this study we had a comparative evaluation among these sites, MBC, KBS and SBS, which are the representative broadcasting systems. The tests were carried out as heuristic evaluation and usability testing. We analyzed causes and problems of web usability for customer satisfaction and reliability exaltation, and expected the basic knowledge of developing and improving sites.

Korean web drama are undergoing changes before and after the popularization of the OTT platform. The previous web drama were mainly aimed at teenagers, with school content as a genre feature, and the active casting of new idols and the use of B-grade emotions as production characteristics. After the popularization of OTT represented by YouTube and Netflix, there are signs of significant change. This study examined the hyperrealistic content characteristics of the web drama , which can be the center of the change. Through this, it was considered that has a greatly changed aspect from previous web dramas through stereoscopic typification, emphasis on detailed expression, active use of experiential narrative characteristics, and a new media creator-centered production method.

The use of web widgets on desktop and mobile devices has been increasing rapidly. Web widgets provide access to activities and information from various sources across the web. As the number of supported widgets increases, managing widgets and finding relevant or interesting widgets becomes more complex. In addition, interacting with widgets in web service systems can be difficult, especially for novice users. Up to this point, there has been little research on web widget usability. This paper performs an experimental study regarding user interfaces of web widgets based on the mouse tracking and work-flow analysis. In the experiment, four sites providing widget services are chosen - iGoogle, Netvibes, My yahoo, and Wizard. The experiment participants perform three assigned tasks in the chosen sites, and their mouse operations are recorded using Camtasia, a screen casting software. Mouse tracking analysis is performed based on the recorded data in order to analyze common user behaviors. In addition, work-flow diagrams representing the operational flows to carry out the given tasks in each web site are constructed so as to visually and systematically analyze detailed usage patterns. The experimental study results presented in this paper can contribute to developing guidelines for highly usable and accessible interface design of web widgets.

Prestressed hollow-core slabs (HCS) are widely used for modern lightweight precast floor structures because they are cost-efficient by reducing materials, and have excellent flexural strength and stiffness by using prestressing tendons, compared to reinforced concrete (RC) floor system. According to the recently revised ACI318-08, the web-shear capacity of HCS members exceeding 315 mm in depth without the minimum shear reinforcement should be reduced by half. It is, however, difficult to provide shear reinforcement in HCS members produced by the extrusion method due to their unique concrete casting methods, and thus, their shear design is significantly affected by the minimum shear reinforcement provision in ACI318-08. In this study, a large number of shear test data on HCS members has been collected and analyzed to examine their web-shear capacity with consideration on the minimum shear reinforcement requirement in ACI318-08. The analysis results indicates that the minimum shear reinforcement requirement for deep HCS members are too severe, and that the web-shear strength equation in ACI318-08 does not provide good estimation of shear strengths for HCS members. Thus, in this paper, a rational web-shear strength equation for HCS members was derived in a simple manner, which provides a consistent margin of safety on shear strength for the HCS members up to 500 mm deep. More shear test data would be required to apply the proposed shear strength equation for the HCS members over 500 mm in depth though.
