When using conventional 3D image scanning methods, it is common for image scanning to be done manually, which is labor-intensive. Scanning a space made up of complicated equipment or scanning a narrow space that is difficult for the user to enter, is problematic, resulting in quality degradation due to the presence of shadow areas. This paper proposes a method to scan an image using a rover equipped with a scanner in areas where it is difficult for a person to enter. To control the scan path precisely, the 3D image remote scan automation method based on the rover move rule definition is described. Through the study, the user can automate the 3D scan plan in a desired manner by defining the rover scan path as the rule base.

We have developed an interactive signage system based on floating hologram by combining hologram technology and ICT technology, which can be competitive to small businesses that have excellent products and services. The developed interactive signage system can be used for publicity and marketing of small business owners at low cost, introducing menus with 3D hologram images, and providing various contents responding to user's hand movements. The developed system is able to detect 10 finger movements at a rate of 290 frames per second in a range of 60cm and a range of 150 degrees. We also confirmed that the virtual touch function operates normally by dividing the user's motion recognition into the hover zone and the touch zone by the physical motion experiment of the leap motion object.

Prior to the concrete and practical use of closed schools, this study was designed to identify trends in the use of closed schools, and the possibility and direction of the library's use of closed schools based on the status of closed schools and use cases. As a result of the case analysis, the building of libraries using closed schools can be reborn as libraries with different characteristics from general public libraries, such as providing complex cultural spaces, eco-friendly spaces, and local community places. In addition, based on the results of the study, future direction of library closure is suggested as follows: Provide local economic contribution and local revitalization opportunities, life-friendly and friendly space for local residents, recycling space linked with elderly welfare, care service, urban to rural Immigrants, creation of added value and creation of local business using closed schools, environment-friendly space, recycling as a complex community center, recycled into a space that meets and complements local needs.

Early Smart TV market had their interest in the ability of HW, but these days Smart TV market begin to concentrate on it's services, contents and applications of SW. However, because in Smart TV application, there is no major difference with the application in smart phones and tablets. So the utilization rate in Smart TV application is evidently low. That's the reason why many people did not feel the need to use smart TV applications. In order to solve this problem, this paper propose to develope an application with the cloud computing technique [clould computing] that is intended to provide an usability through the interlocking of the individual PC and smart phone. After uploading user's photos from smart phone or PC to smart TV, this application will help not only to create user's own video but also to add various kind of video effects that user want. Therefore, in this paper, I expect the activation of smart TV applications.

This study used data from the 3rd and 11th year of the Korean Welfare Panel to evaluate the effects of the Long-Term Care Insurance(LTCI) system on the consumption and expenditure of LTCI users' households. The study consisted of program group using LTCI and control group not using. Chi-square and t-test were used for the characteristic differences among the groups, and the difference of consumption expenditure was identified by multiple regression analysis. As a result, LTCI had a statistically significant effect on the health care costs of LTCI users' households, resulting in an increase in health care costs(${\beta}=3.06$). However, there was no statistically significant effect on the total cost of living, basic cost, education cost, and recreation/entertainment cost. Therefore, in order to show the effect of LTC system, we should try to reduce of self-pay and improve the contents and quality of the service of the LTC system.

Developing countries, including Africa, are experiencing very little human resources development due to the deprivation of equal educational opportunities, poor educational conditions, and the gap in information technology with developed countries. Developing countries that do not have excellent human resources are lagging behind in globalization competition with developed countries, and the problem of 'human resource development' in developing countries can not be avoided. In developing countries, education budgets are too low to meet education needs and compulsory education, and therefore they are not adequately responding to the increasing demand for education. The lack of education budget is due to the lack of education infrastructure. In this study, the NAS based server is configured to configure functions such as educational content and learning management, and the client area is presented with solutions for various media such as tablet, PC, and beam projector. And to support optimized e-learning services in developing countries by constructing a SCORM-based platform.

The purpose of this study is to assess usage of floating action button, a component of Google's Material Design. Case studies were conducted to overview the component's current usage and qualities, followed by eye-tracking experiments and in-depth interviews conducted to 12 subjects. Results have shown that while floating button can promote an action by catching viewers' attention with its striking visual, users tend to look at top more, thus preferring top placement for interfaces. To give positive user experience, designers should consider factors such as the amount of content covered by the button, the way users interact with the application, etc. This study aims to provide proper guidelines for the component's application.

This study aims to provide the basic functional requirements and degree of importance of online archival exhibitions, which have played an essential role in the records information service lately. It first derived the properties of online archival exhibitions and their functional attributes through literature analysis. Next, it analyzed the degree of importance of functional requirements using the analytic hierarchy process (AHP) method. As a result, 3 properties and 13 functional requirements of online archival exhibitions were proposed. It was found that the archivists managing the online archival exhibitions considered the most important property to be "Information Transmission," the second the "Effectiveness of Exhibition," and the third the "Informative Function." As for the most critical functional requirements, these are "Aesthetics," "Interaction," "Usability," "Educational Experience Provision," and "Promotion and Exhibition Activation," while the least are "Theme Originality" and "Content Inclusiveness."

This research categorizes the factors of digital capital accumulated both in personal and social level into digital access and digital competence, and empirically analyzes how the use of public libraries effects on the formation of digital capital. As a result, it was found that participation in public library programs, the use of information services, and the utilization of digital collections had positive effect on the formation and accumulation of digital capital at the personal and social level. In contrast, it was analyzed that the use of digital collections in public libraries did not significantly affect the creation of digital contents or reciprocal collaboration based on online networks. Therefore, in order for public libraries to fully support the formation of digital capital, they should not only provide knowledge and information which is a traditional role of public libraries, but also play a role as a digital-based cooperative system.
