Due to the bitter competition in markets and the need changes of consumers, customer relationship management(CRM) plays a key role in determining management strategies in companies. In addition, due to the advance of Ubiquitous environment, new applications are developed in the CRM arena. Since traditional data gathering methods can invade people's privacy and cause inaccurate data, new methods are required. In this paper, we propose an RFID-based automatic analytical information generation system for a ubiquitous CRM. Firstly, we develop an RFID middleware. And then, we store the data acquired from the middleware into a database. Finally, we analyze the data automatically and convert the data into meaningful information. By applying our system to an exhibition hall, automatically generated analytical information are given to companies and customers. The proposed system can make many companies meet their customers' needs in a ubiquitous way and can give them more accurate data by using clustering, associating, sequencing when they make a decision for their successful marketing.

This study presents an application of GIS technologies to construct the graphic user interface for 3-dimensional exhibition of the results obtained by ocean hydrodynamic model. In coastal management studies, GIS provide a receptacle for scattered data from diverse sources and an improvement of the 3D visualization of such data. Within the frame of a GIS a variety of analytical, statistical and modeling tools can be applied to transform data and make them suitable for a given application. A 3D hydrodynamic model was driven by time-dependent external forcing such as tide, wind velocity, temperature. salinity, river discharge, and solar radiation under the open boundary condition. The Jinhae bay was selected as a case study. Here, we have used GeoMania v2.5 GIS software and its 3D Analyst extension module to visualize hydrodynamic model result that were simulated around the Jinhae bay.

In order to actualize the third dimension form, hologram is coming to attention because it has no restriction on viewing position and is capable of natural visual expression. Although hologram technology is the best method to embody 3D image without glasses, it is not commercialized due to several technological problems. Currently used hologram technology in concerts or exhibitions are images flashed on a 2-dimensional transparent screen by HD projectors which is similar to hologram technology, not truly same. In this research, we make 3D contents for Holographic projection and use these contents to present art that can interact with spectators. As a result of the exhibition, attendance showed satisfaction on inspection form, allowing spectators to move around the screen and view it both sides; moreover, they were enterprising to interact with the videos played according to their movements. Therefore, we are able to implement a sensible and spatio-temporal artwork along with interesting space production and represent a intimate and interactive space with the public.

As humanoid robot technology advances, the use of robots for performance is increasing. As a result, studies are being conducted to increase the scope of use of robots in performances by making them natural like humans. Among them, the use of motion capture technology is often used, and there are environmental inconveniences in preparing for motion capture, such as the need for IMU sensors or markers attached to each part of the body and precise high-performance cameras. In addition, for robots used in performance technology, there is a problem that they have to respond in real time depending on the unexpected situation or the audience's response. To make up for the above mentioned problems, in this paper, we proposed a real-time motion capture system by using a number of RGB-D cameras and creating natural robot motion similar to human motion by using motion-captured data.

Recently, virtual reality contents are being experimented and introduced in various fields such as game, education, medical, exhibition, movie, SNS. However, research on virtual reality is mainly focused on industrial and technological perspectives, so contents-centric or contents-oriented research is on virtual reality is very rare. In order to prepare for the future of virtual reality properly, content-oriented research is very much needed. The purpose of this study is to investigate the types, characteristics, and possibilities of virtual reality contents applied to theme parks. For this purpose, we tried to classify the contents type of virtual reality based theme park. The criteria of type classification are divided into 'fixed type', 'continuous moving type', and 'segmented moving type' according to the player's position movement possibility and movement type, here we combine the senses such as tactile, taste, smell, balance etc.

This study investigated whether search terms analysis of archival Web sites could be utilized effectively for archival information services. The focus was on designing a methodology which brings the search terms analysis and development of archival information services closer, especially for the contents services. The data were collected from the Presidential Archives because it can be characterized as a public archives as well as subject archives. It also tends to draw interests from a broad range of general public. The analysis was conducted with respect to three dimensions: (1) general search terms; (2) names of individual president; (3) subject categories of search terms. The results of search terms analysis have a number of practical implications for developing archival information services including contents services, decision on the menu of the Web sites, exhibition, and education.

The purpose of this study was to investigate the existing augmented reality (AR) contents in education and to develop digital AR contents to promote the learning outcomes in nursing skills education. AR contents has been widely used in education such as children's books, coloring, or exhibition experiences, but rarely developed in nursing education. We wanted to develop AR contents on nursing skills which required memorization of complex contents. In order to improve nursing students' memorization skills, we developed AR techniques holding and executing cameras along with game elements of time and points. In order to give the effect of placing objects in front of the user's eyes, an augmented reality camera was applied, and a total of 40 levels were created to produce the sequence of nursing techniques. This study showed that learning contents in the medical field requiring expertise could be implemented as AR contents. The content developed in this study will be used as a learning aid for nursing students.

This study analyzes convention tourism destination brand slogans focusing on the international convention cities. Data were collected from official tourism web sites of 190 cities which hosts more than ten international meetings in 2013. One hundred and six destination brand slogans were identified. Specifically, the researchers attempt to carry out content analysis of the linguistic and visual expressions of the slogans. Results indicated that in terms of linguistic expressions, most of slogans adopted word or phrase patterns pursuing brevity. In the brand slogan spectrum, nearly half of slogans are common type which didn't express destinations' specific attributes and benefits properly. And the most frequently used key words in the slogans are 'visit' and 'city'. While in terms of visual expressions, about 70% of slogans adopted typography for explicitness and 60% of them utilized human and natural resources as visual signs for building up unique images. Based on the results, implications for creating effective convention tourism destination brand slogans were also discussed.
