This paper proposes a Web Based Online Outage Cost Assessment and Information System(WOOCAIS) for power system outage cost assessment. The proposed WOOCAIS is a kind of web based survey method for outage cost assessment. While conventional survey methods have done outage cost assessment based on survey paper lists collected by post mail or visiting customers, the proposed WOOCAIS is a web based online survey operation and assessment system. Therefore, it can curtail expenditure for survey and also is more convenient than conventional method. It will be set up for actual outage cost assessment system of KEPCO in South Korea in the near future. The WOOCAIS will be applied in various research and actual planning and operation areas. First of all, the assessed results may be not only applied as one of objective function for generation system and grid expansion but also operational planning problems in power system.

The purpose of this study is 1) to investigate the Web content of online shopping agencies and to see if differences exist in their contents and 2) to suggest strategies for online shopping agencies. For the study, the online shopping agency components of web sites were investigated, which consisted of product, information, and customer service. Each component had sub-categories. In order to analyze the Web content of online shopping agencies, nine agencies were chosen based on the rankings of www.rankey.com and www.100hot.co.kr. The content analysis was conducted from January 5th to the 30th of 2009. The results showed that the basic Web content of online shopping agencies (i.e., product, information, and customer service) was evident on most sites. However, products were similar and effective information and labor-saving functions were sparsely used. Areas where customers actively participated were limited. Therefore, most sites need to reinforce their content by providing a well-articulated product, information, and customer service for shoppers and to differentiate their Web site identities.

This study is to identify whether three types of online instruction (text-based, video-based, and video-based instruction without text) and age category have a different influence on students' comprehension and motivation. Online students were randomly assigned to one of six groups, and they attended two-week online lectures via Course Management System. The comprehension test and the short form of IMMS were implemented when 114 participants accomplished two-week online lectures. The results revealed that using instructional video in online instruction is more effective instructional medium than text only in order to promote learner's motivation. Besides, older adults aged 41-60 are significantly different from younger adults (21-40 years old) in terms of students' comprehension. Furthermore, three types of online instructions are likely to be influenced by age category.

In this paper, we suggested a model that reflects the role played by the consumer's regulatory focus (promotion focus and prevention focus) as determinant factors of trust in the Web site. Also, we considered the moderating effects of consumers' purchasing experience toward online shopping. We conducted a two-month survey of 230 individuals using online shopping sites for hypotheses testing. The study results are summarized as follows. Firstly, promotion focused consumers showed higher trust to a web site compared to prevention focused consumers. Secondly, the moderating effect of purchasing experience between regulatory focus and consumer trust to a web site is statistically significant. The effect of a prevention focused consumers on consumer trust to a web site is stronger when purchasing experience toward online shopping is high compared to low. Based on these findings, this study presents practical and academic implications of the research.

This research categorizes and analyzes different online fashion store studies conducted over the past 10 years based on study type. The results are as follows. First, it was found that 116 studies out of 118 studies on online fashion stores conducted from 2000 to 2012 were based on PC web. Second, the studies on PC web-based fashion stores were reclassified into 9 different categories based on their topics: purchase behavior, word-of-mouth behavior, website, and product information presentation as well as products for sale, return behavior, customer service, system, present condition, marketing strategy, and promotions. However, mobile web-based studies were categorized into 2 categories of introduction of the fashion stores and purchase behavior. Third, we reclassified the studies chronologically to observe studies conducted at different times. In the early phase (in addition to studies on purchase behavior) studies on present condition, marketing strategy, and website constituted the majority of studies conducted because the field research was just starting to grow; however, studies conducted in the latter phase showed new patterns of study, such as word-of-mouth effect, and return behavior. Future studies conducted on competitive PC web-based fashion stores require a more specific classification of studies (according to their purpose) to develop an effective marketing strategy.

Currently, web-based online games is becoming popular in supporting learning process due to their effective and efficient tool. However, online games have lack of security aspect, in particular due to increase in the number of personal information leakage. Since the data are transmitted over insecure channel, it will be vulnerable of being intercepted by attackers who want to exploit user's identity. This paper aims to propose an online web-based educational game, Vidyanusa which allows the students to register their personal information using a unique code, a user name and a password. It manages the users according to their schools, subject teachers and class levels. In addition, by adopting a unique code, the confidentiality of the user identity can be kept away from attackers. Moreover, in order to provide a secure data communication between client and server, Secure Socket Layer (SSL) protocol is adopted. The performance of the system after implementing SSL protocol is examined by loading a number of requests for various users. From the experiment result, it can be concluded that the SSL protocol can be applied to web-based educational system in order to offer security services and reliable connection.
