Recently, the researches based on vision about user attention and action awareness are being pushed actively for human computer interaction. Among them, various applications of tabletop display system are developed more in accordance with touch sensing technique, co-located and collaborative work. Formerly, although supported only one user, support multi-user at present. Therefore, collaborative work and interaction of four elements (human, computer, displayed objects, physical objects) that is ultimate goal of tabletop display are realizable. Generally, tabletop display system designs according to four key aspects. 1)multi-touch interaction using bare hands. 2)implementation of collaborative work, simultaneous user interaction. 3)direct touch interaction. 4)use of physical objects as an interaction tool. In this paper, we describe a critical analysis of the state-of-the-art in advanced multi-touch sensing techniques for tabletop display system according to the four methods: vision based method, non-vision based method, top-down projection system and rear projection system. And we also discuss some problems and practical applications in the research field.

This is a study to establish the feasibility in terms of the use of the J library, which will be built in Jurye-dong, Sasang-gu, Busan. Accordingly, this study conducted a community analysis and user survey to confirm the necessity of building a library and suggested directions for services that the library should provide in the future. To this end, a community analysis was conducted primarily on Sasang-gu, such as population distribution status, cultural institution status, and Sasang-gu vision. Afterwards, visitors to Sasang Library, Small Library, and Community Center were surveyed on the status of use of existing public libraries and the awareness of J Library to be built in the future. As a result of the survey, the necessity and intention to use J Library were found to be high, and the expectation for prompt provision of sufficient printed materials such as books and magazines was the highest. In the case of the desired space, the demand for 'open space' and 'small meeting space(family room)' was high, In the case of specialized services, there was a high demand for humanities, arts & music, movies, etc., but it was shown that they showed a general interest in various fields.

Purpose The purpose of the study is to identify the need of a mobile based library information and service delivery system in developing countries, identify the services that are possible to provide with the help of mobile phones and their applications, design a mobile based library information and service delivery system, and identify major challenges regarding mobile based library information and service delivery systems.Design/ Methodology/ Approach The research is exploratory in nature. This paper is based on a review of literature, survey information, and on the author’s own viewpoints. A comprehensive search of scientific literature has been done along with a survey for validating the necessity of designing mobile based library information and service delivery systems. Responses to closed-ended questions in particular on 7-point Likert scales were analyzed using the descriptive analysis techniques of SPSS 20.0 and responses to other closed-ended questions were analyzed using general statistics.Findings The research indicates that users of academic libraries, especially students and faculty members, have a positive notion regarding designing and implementing a mobile based library information and service delivery system. It also reveals user opinions regarding the possible problems associated with the design and implementation of a mobile based library information and service delivery system.Originality The paper explores mobile based library information and service delivery systems for better and faster service provision to its potential users.

Purpose: The aims of this study were to evaluate the dentist's awareness and the actual status of infection control of noncritical dental instruments. Materials and Methods: 40 dental clinics in Daejeon, South Chungcheong, North Chungcheong and North Jeolla provinces were surveyed. The questionnaire was delivered to the dentists belonging to those clinics, and the awareness and the practice of infection control were examined. The microbial contamination on the surface of five noncritical instruments (impression gun, light curing unit, 3-way syringe, shade guide, and dental floss dispenser) used by them was measured with an ATP luminometer. Correlation analysis between the awareness and the actual state of infection control was conducted. Results: Awareness and frequency of infection control was highest in the 3-way syringe. Surface disinfection using disinfectant was most frequent in all instruments. 3-way syringes and shade guides were less contaminated than impression guns, light curing units, and dental floss dispensers. Conclusion: 3-way syringes had a significant correlation between user awareness of infection control and surface contamination, and the higher awareness, the lower the contamination measurement was shown.

This study aims to present a direction for securing continuous growth and confidence, centering on two Internet banking companies that started recently. The banking market has been rewriting the history since the emergence of Internet professional banks. In order to improve the credibility and promote the development of the Internet professional banks, I conducted a questionnaire survey and In Depth Interview. As a result of this survey, the overall reliability is still low, and the factors affecting reliability are: 1.Security problem 2.Discomfort of customer service 3.Errors and unnecessary services. This is a start-up business, so the awareness and reliability can be changed soon. Therefore, it is necessary to continue research on this according to the changing user's perception.

This study aims at understanding the fundamental characteristics of EV consumer based upon user survey and understanding the challenges to promote EV adoption in Korea. Data are obtained from two different surveys. One asked 304 EV buyers in Korea and another asked 905 prospective customer about EV awareness and perception, EV purchase intention, and etc. Analysis is composed of two parts; one is about the general characteristics and purchase intention of general consumers; another is about the intent to repurchase EV owners. We discuss the policy implications to expand EV demand in Korean market based on two purchase and repurchase logit models.

This study intended for Yokohama Minato Mirai21 district in Japan as waterfront, and Korea did an object again in Haeundae on high ground beach, a Jagalchi market. I carried out questionary survey in an object with the three places and investigated human waterside space consciousness to keep that I came and went. I analyzed the waterside space consciousness of the user to see a questionnaire result. It was 78.7% of 237 people, and there was much 'which felt the' sea breeze for the waterside space consciousness most, and 'that' which the 'sea was seen next saw 217 72.1%,' ship appeared by 203 67.4% order. I carried out reclassification for human five senses (sight, hearing, the sense of touch, taste, sense of smell) and activity, seven items such as the existence of the institution by the question contents of 19 about the waterside space consciousness each and grasped the consciousness of the waterfront user. As a result, Haeundae sense of smell was 32.3%, and a Jagalchi market was that sense of smell (26.1%) had an influence on the waterside space consciousness in 32.3% of taste, 21, Minato Mirai, Yokohama district, and sea building on high ground beach appeared.

In the Fourth Industrial Revolution, students are required to develop in areas such as communication, logic, and creative thinking. Therefore, the university libraries need to develop new services so that students can grow up to be suitable for the new social situations. Havruta is an educational approach that can meet these needs and is one of the measures the university libraries want to apply. Thus, through 1) the investigation of the concept of Havruta, 2) the case study of domestic and foreign university libraries, and 3) interview of the Havtura-based service, this study 4) proposed the Havruta service applicable to the university libraries and 5) conducted a survey of operators and users on the awareness of the Havruta service, space, and contents of the Havruta service, and the willingness of the Havruta service. Results of the survey analysis revealed implications for the areas of the Havruta service - Havruta theme, group organization, textbook rental, simplication of space reservation, data sharing and motivation system.
