This paper proposes a mobile augmented reality mashup for cultural heritage sites such as natural monuments. Several benefits of mobile augmented reality solutions are ideal for preserving and protecting cultural heritage sites. By presenting mobile augmented reality mashup scenarios and mobile mashup framework, we introduce how user-generated multimedia contents can be added. We present two scenarios of Mashup Viewer and Mashup Maker. In Mashup Viewer mode, visitors can create new AR contents using mashup tools for memo, Twitter, images and statistical graphs. In Mashup Maker mode, other visitors also can view the user-generated multimedia AR contents using QR codes as access points. To show feasibility of our approach in mobile platforms, we compare several detection algorithms on PC and mobile platform and report on deployment of our approach in a natural monument museum. With our proposed mashup tools, visitors to the cultural heritage sites can enjoy default AR contents provided by the site administrators and also participate as active content producers and consumers.

Webtoon is the most popular cultural contents representing contemporary Korea. This study explores the cultural aspects of participatory culture surrounding Webtoon, and reveals the cultural implications of webtoon in contemporary Korea. Particularly, this study notes that the engagement of the participatory culture is formed from the user-generated images and analyzes the reproduction patterns of them. Chapter 2 analyzes the mimicking process of user-generated images based on the 'meme' concept. Especially based on the variation degree of text or image, the user-generated images could be classified into three types of 'completely variant', 'partly variant', and 'completely same'. Users use these images as one of the fun factor by transplanting them into daily messenger conversation. Chapter 3 reveals the cultural meaning which is derived from the process of user-generated images creation. In particular, this study notes that most of the user-generated images are mimicking the main character of the original webtoon, and analyzes the underlying desire of the mass based on the literary theory of Northrop Frye. The main readers of webtoon are petit-bourgeois living in Korean metropolitan, and the user-generated images also reflects the daily lives of these ordinary people. User-generated images of webtoon are imitating the original contents in a way of replicating or mutating the images or texts. Also, they are consumed and enjoyed as an amusing code among users. Especially by mimicking the appearance of the main character in a self-reflective way, they appeal to day-to-day sympathy of users. In that user-generated images reveal the desire of the public living in contemporary Korea, this study examines the cultural implication of webtoon.

One of the key factors for success in fostering web-service is the supply of user-generated contents(UGCs). Technological interactivity is an environmental factor which stimulates user-content interaction, and reflects the system's capability for supporting various interactions that are allowed by a medium. The present study uses a structural equation model to investigate the influence of three components of technological interactivity-user control, synchronicity, and responsiveness-on web-services' perceived content performance. The results show that web-services' user control and synchronicity exhibited a positive relationship with the perceived efficiency of content generation; further, perceived efficiency boosts perceptions of content quality, which means that the user control and synchronicity of a web-service also have an indirect effect on perceived content quality. Additionally, responsiveness has a positive effect on perceived content quality. These findings are important for marketers and operators seeking to make their web-service successful.

In this paper, we present a structure of personalized e-Learning system to study for a test formalized by uniform multiple-choice using on/off line mixed estimations as is the case of Driver :s License Test in Korea. Using the system a candidate can study toward the license through the Internet (and/or mobile instruments) within the personalized concept based on IRT(item response theory). The system accurately estimates user's ability parameter and dynamically offers optimal evaluation problems and learning contents according to the estimated ability so that the user can take possession of the license in shorter time. In order to establish the personalized e-Learning concepts, we build up 3 databases and 2 agents in this system. Content DB maintains learning contents for studying toward the license as the shape of objects separated by concept-unit. Item-bank DB manages items with their parameters such as difficulties, discriminations, and guessing factors, which are firmly related to the learning contents in Content DB through the concept of object parameters. User profile DB maintains users' status information, item responses, and ability parameters. With these DB formations, Interface agent processes user ID, password, status information, and various queries generated by learners. In addition, it hooks up user's item response with Selection & Feedback agent. On the other hand, Selection & Feedback agent offers problems and content objects according to the corresponding user's ability parameter, and re-estimates the ability parameter to activate dynamic personalized learning situation and so forth.

The study aims to examine the UCC (User Created Contents) Copyright which use the broadcasting contents. UCC are classified by UGC(User Generated Contents), UMC(User Modified Contents), and URC(User Recreated Contents). Especially UMC and URC correspond to a problem of copyright. Following the Copyright Protection Center investigation in 2006, it reported that 83.7% UCC are infringement of copyright. In spite of remarkable the UCC copyright problem, the concrete resolution does not exist. Also it is difficult to apply the offline legal conformity because of online nature of the UCC. The study observes the UCC copyright dispute instances which use the broadcasting contents and investigates a resolution of the UCC copyright. Considering the online media nature, it tries to analyse CCL(Creative Common License) as the ODR(online Dispute Resolution). It is meaningful to search the possibility of UCC copyright problem through the online technical embodiment.

As one of the successful brand activism ad campaigns in recent years, the current study focuses on the Always #LikeAGirl campaign that took on the issue of girls and female empowerment. As a viral video marketing campaign with YouTube as their main vehicle for campaign dissemination, this study examined how Always brand activism campaigns spread on YouTube by conducting a network analysis of YouTube video networks generated by the #LikeAGirl campaign spanning across five campaign periods. Quantifiable data (i.e., views, comments, likes, dislikes, user-generated videos) and structural network patterns show that the Always #LikeAGirl campaign was successful by both standards. Although the follow-up campaign periods were not as successful as the initial campaign, the substantial amount of views, comments, likes, and user-generated content showed that the consecutive campaigns still had impact. As shown through the network patterns, the main campaign ads were central in the diffusion of the campaign during the earlier periods but that role was passed onto the user-generated contents in the later periods. Implications of the findings and future social network analysis studies in brand advertising and brand activism campaigns are further discussed.

The Q-cost has been used in the manufacturing company to decide the optimal level of company's product quality, and to evaluate the effect of company's quality control system since the advent of Q-cost theory. In spite of the following costs are generated in the user side, owing to an unsuitable level of product quality and inadequacy of company's quality control system, these costs are not usually included in the company's Q-cost : (1) the cost generated in relation to a claim proposal as traffic expeneses and transpotation of the product. (2) the cost of maintenance through the useful life of the product, especially accured after quality warranty period. (3) the cost related to the economical efficiency in using the product. (4) the cost ralated to a customer dissatisfaction for the product quality. In this point of view, the contents of user side Q-cost, and the relations between the user side Q-cost and the level of company's product quality are discussed. And then the importance of user side Q-cost in order to determine the optimal quality level is discussed.

Until now, most of the Web GIS system has been developed with one-sided service type that provides pre-built spatial information to users. Recently, however, interactive web system is getting attention because users can create directly spatial information contents that meet their needs. In line with this trend, this study had a aim to develop a UGC(User Generated Contents) support system for marine science researchers who can generate spatial data by themselves on the web. The main advantage of this system is that it provides marine survey data and marine spatial information that needed to work for marine science research. Furthermore, it provides the functions of extracting of coastline as point data for their marine study area, and making of the spatial planning map for marine field survey work and marine science thematic maps for exploratory analysis after research survey. Such kinds of interactive UGC support system gives researchers a chance for utilizing marine spatial information more easily. Therefore, it is expected that the improving of the efficiency of research works, as well as increasing of the utilization of marine spatial data.

While numerous studies have suggested the significance of uncertainty during the process of information-seeking, less research has investigated user uncertainty in the actual search process using a real system. This study investigated user perceptions of uncertainty in the process of the selection of information retrieval system in the real information-seeking process. Considering the role of commercial Web search engines as supplementary tools for traditional bibliographic databases in academic research environments, this study analyzed the selection behavior of scholarly researchers, who use such search tools for their academic study. The researchers were limited to the discipline of science in order to understand user perceptions in this field. The findings revealed various dimensions, types, and incidents of uncertainty. Variations appeared in different incidents of uncertainty relating to the unique characteristics of the subjects' information-seeking context. The identification of three principal origins of uncertainty based on the different types of uncertainty generated implications to improve information systems and services.
