By virtue of diverse advantages derived from digital media, eBook is getting started to use. And many market research agencies have predicted that its market will be greatly expanded soon. But against those expectations, copyright-related problems and the difficulties of its accessing inherited from various eBook content formats become an obstacle to its diffusion. The first problems can be solved by DRM technology. And to solve the second problems, each nation has published its own content standard format. But the domestic standards are useful only the domestic level, they still leave the problems in the national level. The variety of content formats has created a demand for mechanisms that allow the exchange of eBook contents. Therefore we study the mapping relations between eBook contents for conversion. To define the mapping relations, first we extract the mapping both between eBook contents and between normal XML documents. From those mappings, we define seven mapping relations and classify them by cardinality. And we analyze the classified relations, which can be generated by automatic, or not. Using these results, we also classify the eBook content conversion as automatic, semi-automatic, and manual. Besides, we provide the conversion templates for mapping relations for automatic generation of conversion scripts. To show the feasibility of conversion templates, we apply them to the eBook content conversion. Experiment shows that our conversion templates generate the conversion scripts properly. We expected that defined mapping relations and conversion templates can be used not only in eBook content conversion , but also in normal XML document conversion.

The development of social media in the 2000s led the unspecified individuals to band together for common interests. Social networking services served as a far-reaching tool for sharing different thoughts and interpretation of the pop culture and helped people build up close relations driven by their common interests for certain works of the pop culture. This Study introduces the TV Series as a case that displays specific patterns of communication between its producer and viewers. Producer Bryan Fuller of the Series as well as key production staffs were quite active on social networking sites with the understanding of what the audience desired and the willingness to sympathize with them, which were eagerly welcomed by the dedicated audience whose number, though, was not big. For the Hannibal production team, SNS was a means for them to just be consumers who appreciate the work instead of solely being the content provider. Their approach is quite different from unilateral marketing approaches employed in the past. Through this case, the Study aims to suggest that social networking sites serve as a powerful medium connecting producers and viewers or as an information hub, and that how interactive contents shall be delivered in the new media environment to be effective.

In the new web based learning environment which has recently emerged, a variety of new learning objectives and teaching methods suited to this learning environment have been adopted. Recently, web based project-based learning methods have received a great deal of attention from those wishing to improve learning performance. The objective of this study is to identify the impact of characteristics of communication media and instruction behavior on collaborative interaction and project performance through web based group projects. The characteristics of communication media were divided into richness, flexibility, and ease of use, and the characteristics of instruction behavior were divided into support and expression, which are independent variables. Collaborative interaction as a mediate variable, was divided into information sharing and negotiation. Project performance was the dependent variable. To verify the proposed research model empirically, an experiment was conducted in which learners participated in on-line and off-line courses with group projects. The group project was conducted virtual product development(VPD), and designed a web-site about the VPD. At the end of the project, a survey was conducted. Of the 270 students, 239 responded. The students were assigned to groups of 3 or 4 members, and represented different genders and levels of computer competence. The reliability, validity, and correlation of research variables were analyzed using SPSS 14.0, and the measurement model and the structural goodness-of-fit of the research model were verified through SEM analysis using Lisrel 8.54. We found important results as follows; First, richness and ease of use has positive impacts on each of sharing information and negotiation. This suggests that richness and ease of use are useful in sharing information which is related to the task and agreeing in opinions among group members. However, flexibility has not positive impacts on sharing information and negotiation. This implies that there is no great difference in performance of PC and information literacy of user. Second, support and expression of instructor have positive impacts on sharing information and negotiation. This indicates that instructors play an important role in encouraging learners to participate in the project and communicating with them, sharing information related to the project, making a resonable decision and finally leading them to improve a project performance. Third, collaborative interaction has a positive impact on project performance. This result shows that if the ability to share information and negotiate among students was improved then a project performance would be improved as well. Recently, in the state of revitalized web based learning, it is opportune that web-based group project is practically conducted, and the impact of characteristics of communication media and characteristics of instruction behavior on sharing information, negotiating among group members and improving a project performance is verified. On the basis of these results, we propose that forms of learning, such as web based project, could be one of solution which is to enforce interaction among learners, and ultimately improve learning performance. Moreover web-based group project is able to make up for a weakness which makes it difficult to make interpersonal relations or friendship among learners in computer mediated communication or web based learning.

The purpose of this study is to improve library promotional marketing for the disabled by identifying requirements of public library disability services. This study aimed to investigate librarian service providers' awareness of library programs for the disabled in order to prepare a systematic plan for promoting such library services. Research methods used are a literature analysis and survey. First, the ratio of respondents with experience promoting activities and services for the disabled was less than 50%. Second, regarding methods for promoting library disability services, the respondents used library homepages, press releases, library user guides, library newsletters, and library pamphlets in that order. Third, when asked what kind of PR media the library disability service providers had experience with and how often they use it, library boards and banners were the most common response. Fourth, suggested improvements to the current design and content of PR materials included: clearer word choice (or greater understandability), more detailed descriptions, simpler layouts, and more interesting or eye-catching content in that order. Fifth, the library disability services which are in the most need of public relations were guide information for library disability services, Library and Information Service (DOI services and search services), using alternative materials and the library collection, and aiding the information search. Overall, when evaluating the promotion of disability services in Korea, the library's public relations for disabled services needs to improve because currently neither librarians nor the disabled community they are targeting has frequent or quality experience with it. Thus, the policy department for the library disability services must develop a variety of promotional strategies adjusted for each type of the disability and distribute PR materials to service providers individually, making sure to utilize effective PR methods.

In recent years, micro-blogging services such as 'Twitter' and 'Me2day' have rapidly become major social networking services. However, it is difficult to grasp the relationship between a user and his/her friends in these micro-blogging services because they simply list messages between them in chronological order. In this paper, we propose a visual analytics system that can help the user intuitively understand relationships with their friends on micro-blogging services by enabling them to analyze the messages quantitatively, qualitatively and temporally. In the visual analytics system, we also present a tool to provide the user with valuable advices after classifying the changing relation patterns with his/her friends, which in turn contributes to improving relationships with friends. The proposed system was successfully implemented as smartphone applications to show its potential to be a tool for analyses and improvement of social relations in micro-blogging services.

In order to adapt to the economic change with the rapid world change, the wise consumers should have positive cognizance of their roles and are requested to fulfil their duties as a consummer. Such capability of the consumer could be acquired from home, mass media and school, and specially the role of mother at home would have a great influence on their early children's consummer activities. The purpose of this study was to investigate the interrelationship of the consumer behavior between mother and their children. As a result of this study, the mother with higher educational background could manage effectively the allowance of the children. The mother with older age had a great influence on the consumer's role of the children and high record of the execution. Employed mother had higher level of execution for the consumer's rights than their count part. Accordingly, the consumer behavior of the mother will have an influence on the children's consumer behavior. Such a result showed the meaningful statistic relations(r=3.6, p<.001) for the economy activity of the children the home management and economy life of the mother, and the purchasing activity of the children including the execution of the consumer's right. In their regard, there was the significant statistic relations(r=19, p<.05) between the children's pocket money and the housekeeping management of the mother. In the meantime, it showed that another changing factor concerned with the consumer behavior of the mother have little influence the children's allowance.

The Chinese economic growth rate has been much higher than many countries of the world for many years now. Nowadays, China is experiencing significant economic transformation and structural adjustment. Its speed of development is slowing, and housing and commodity prices are slowly rising. Consequently, a series of economic and social problems have come into being. Under these circumstances, how satisfied are Chinese people on the seven aspects of daily living such as Housing Situation, Household Income, Health, Family Life, Food, Human Relations and Job? The Media and Public Opinion Research Center of Fudan University (FMORC) conducted a phone survey of 606 people living in Beijing, the capital and political and cultural center of China, and Shanghai, the Chinese economic center. The survey results show that the overall satisfaction of Chinese people with their daily life is high. The levels of Family Life and Human Relations are on the top, those of Food, Health and Jobs are listed from the third to the fifth, and satisfaction levels of their Housing Situation and Household Income are on the bottom. The satisfaction levels of males with their Family Life and Health are higher than those of females. Age has a significantly negative correlation with satisfaction with personal health. Monthly income has positive relationships with four aspects of daily life - house income, job, house situation, and family life. Owning a house in cities is another important factor that influences satisfaction with the house situation, house income, food, and family life. Shanghai residents also show higher satisfaction with their health than Beijing residents.

At the interface of two materials with frequency-dependent material-parameters of permittivity and permeability, there may exist two kinds of surface polaritons: surface electric-polaritons(SEPs) and surface magnetic-polaritons(SMPs). Possible combinations of the material-parameters to support propagation of the two surface polaritons are suggested at the interface between metals and metamaterials such as a left-handed material. Dispersion relations are also derived in order to characterize frequency dependence of propagation of the SEP and SMP. It is found that only one propagation mode of SEP or SMP is allowed at a given set of four material parameters, and that counter-propagation of the phase and group velocities of the propagation mode can be observed even in the case when there are no double negative(or, negative-index) materials. Physical origin of the counter-propagation of the group velocity is proposed by evaluating the ratio of two electromagnetic-energy densities of a surface polariton propagating along within the two interface media, and it is confirmed by the dispersion relations.

In the ever-changing medical environment, the social participation of medical doctors is becoming more necessary. Currently, there is not enough participation or action by doctors within our society due to reasons such as a lack of educational curriculum in this area. This study aimed to investigate medical students' opinions and attitudes about social participation and action. A total of 438 medical students were surveyed about their attitudes toward doctors' relations with the public, social participation, social action, and medical education for social participation or action. Regarding doctors' relations with the public, participants responded that the government (73.5%) and the media (82.0%) were causing social distrust of doctors, and more than 70% of the respondents answered that doctors were passive when it comes to social participation. When asked about social participation and social action, 76.7% of the students surveyed had experienced social participation, and 28.3% had experienced taking social action. A total of 73.4% of the students answered that medical education needs to be changed, and it is necessary to introduce subjects such as sociology and law to improve social participation and action. The results are significant in that they show medical students' thoughts on social participation and social action as doctors in the Fourth Industrial Revolution. We believe that a change of medical curriculum to promote active and collaborative social participation by doctors is necessary.
