Map rendering, positioning, database managements are key elements of location based services. Google map and GPS (Global Positioning System) have become a very popular solution for map rendering and positioning, respectively. They are very effective and yet free of charge. However, they cannot be used for an indoor location based service system. We cannot render a building drawing with Google map, we cannot determine a moving object's position when it is indoor. This paper introduces our web services of rendering drawings, indoor positioning, and multimedia contents up-loading and playing so that any programmers can use them in developing indoor location based service systems. In order to experimentally show the efficiency of our web services, we have built a location based contents displaying system for museum visitors with them.

The purpose of this study is to investigate factors related to use-diffusion of Nscreen service as well as consumers' lifestyle and media usage of Nscreen service, which is fundamentally changing both the competitive landscape for business and the daily lives of consumers. The data of 1,524 consumers used in this study were drawn from the first Korea Media Panel Study in 2012 of Korea Information Society Development Institute. This study categorized adopters depending on the usage rate of contents and the variety of media platforms they used. Consumers using various media platforms enjoyed more categories of contents provided by Nscreen services. The variety of media platforms was useful in grouping users to explain the difference between the groups in terms of lifestyle activities. Based on the factor analysis and cluster analysis based on the consumers' lifestyle to find out different characteristics of each clusters, the result elicited some implications.

This paper describes the design and implementation of Personal Mobile Broadcasting Service which bases on embedded Linux and it supports personal broadcasting in wireless network environments. Recently, with the advent of various wireless networks and the increased use of high performance mobile devices, the demand for personal mobile broadcasting is being increased. The personal mobile broadcasting service makes it possible that mobile users create contents using their own mobile devices while they are moving or they are in any place. And then, it sends the created contents to server in real-time where their blogs are. Users connected to the content creator's blog can play the contents in real-time. With the implemented personal mobile broadcasting service, mobile users can share multimedia contents in real-time through wireless networks. And, it also helps users to construct their own broadcasting stations where they can broadcast the scene of the accident or public performance in real-time.

In recent, the cloud computing makes it possible to provide the on-demand provision of software, hardware, and data as a service in various IT fields. This paper uses the cloud computing techniques for the real time broadcasting service of virtual 3D contents. However, the existing related solutions have many problems that the load of the server is rapidly increased or the cost of the server is very high when the number of service users is increased. Therefore, we propose a new application virtualization method to solve these problems. It promises their stable operations in multi-user services because the proposed method does not execute the rendering commands of the application at the host server but delivers and executes them to clients via the Internet. Our performance experiments show that our proposed method outperforms the existing methods.

As the real time multimedia data service has become available due to the rapid progress of computer and Internet technology, the users can enjoy the newly developed service, which is called Video On-Dem-and(VOD). However, most of service providers have not paid their attention much on the software for various service modes on VOD, but they are only concentrating un the hardware to provide with the high resolution video display. Therefore, the service providers are recently to pay more attention on the software to cope with the various demands of users than hardware. So this paper has designed and implemented the VOD service system for those demands. Since the VOD service system suggested by this paper enable off-line search functions through E-mail, the users can possibly get the necessary information from off-line Search without connecting to the server while the current VOD service can prominently help users to save the time and effort to sea고 and select the Video contents by using periodical current awareness service supported by PUSH technology and user oriented information booking and feedback service supported by SDI service.

This paper summarizes findings from investigations into the development and application of English bible study materials for middle school students in two local churches in Seoul, Korea. Six pre-service Christian English teachers have participated in the development of the materials. After the application of the new materials, the pre-service teachers' and bible study teachers' perception of the new materials have been investigated. To analyze the data, the pre-service teachers and bible study teachers were interviewed. The interview data was recorded, transcribed and analyzed based on content analysis method. The findings indicated that the pre-service teachers' church service learning gave them a sense of satisfaction and it also helped them develop professionalism in teacher education. To both the pre-service teachers and bible study teachers, keeping balance between bible teaching and English teaching was found to be a difficult task. The fact that the themes in the new materials are closely related to the lives of the students has been positively evaluated by the bible study teachers.

The purpose of this study is to derive the suggestion of satisfaction of e-book services on the basis of the recent literature on quality assessment for e-service which have been mainly studied on library realm. For this purpose, This study added post-management service which is applicable to measure satisfaction of e-book services based on E-S-Qual and Libqual. We expand our scope of service to using of e-book content and services for individual customers, and analyzed the relationship between satisfaction with the system, the content, the after-sale service. On this foundation, existing e-book service companies can offer their services more efficiently, thereby making the e-book content more diverse, along with developing specialized e-book service to increasing their customer's satisfaction. In addition, the latest and diversity is important as well. Moreover, performing rapid post-management services after the sale of the product or service, can be important variables for customer satisfaction. Therefore, not only the system and content, providing required level post-management services by customers can satisfy the existing customers and create new customers.
