The global positioning system (GPS)-enabled mobile phones provide location-based applications such as car and pedestrian navigation services. The pedestrian navigation services provide safe and comfortable route and path guidance for pedestrians and handicapped or elderly people. One of the essential components for a navigation system is a spatial database used to perform navigation and routing functions. In this paper, we develop modeling and categorization of pedestrian path components for smart tour guide services using the mobile pedestrian navigation application. We create pedestrian networks using 2D base map and sky view map in urban area. We also construct pedestrian networks and attributes of node, link, and POI using on-site GPS data and photos for smart pedestrian tour guide in the major walking tourist spots in Jeju.

This paper proposes the design of Vehicular Cyber-Physical Systems (called VCPS) based on vehicular cloud for smart road networks. Our VCPS realizes mobile cloud computing services where vehicles themselves or mobile devices (e.g., smartphones and tablets of drivers or passengers in vehicles) play a role of both cloud server and cloud client in the vehicular cloud. First, this paper describes the architecture of vehicular networks for VCPS and the delay modeling for the event prediction and data delivery, such as a mobile node's travel delay along its navigation path and the packet delivery delay in vehicular networks. Second, the paper explains two VCPS applications as smart road services for the driving efficiency and safety through the vehicular cloud, such as interactive navigation and pedestrian protection. Last, the paper discusses further research issues for VCPS for smart road networks.

The smart phone are changing the way people communicate. And, the mobile app marketplace is greatly fast-growing. The app store continues its rapid growth, there are already more than 900,000 mobile apps on AppStore. We anticipate to see gained momentum throughout the business. Mobile is also becoming popular for marketers. Therefore, specialized app analysis systems are becoming important to how marketers and app developers invest, analyze and market their apps. App analysis systems enable users to discover and analyze behavior through data observations and meaningful patterns. In this paper, we introduce app analysis system and CMS System Open API, NugaLog. The NugaLog acquires users data and engages with them in a variety of ways. It will be essential for us to understand how users interact with and move through the app. The NugaLog will be able to see the number of users, smart phone model, smart phone OS, resolution, page views, and app version.

In recent, android application developments have been done widely that intensify smart phone utilization. In this paper, we propose a curriculum that undergraduate students can improve their mobile programming abilities as well as integrate experiences of application development based on android. And also a series of practices to advance their sense of accomplishment are added by offering an opportunity to carry out a real project to use a variety of sensors embedded in smart phone during the course of study. The project is composed of a series of modules for implementing a trekking App that helpful to people who enjoy spending time in outdoors through their favorite activities such as trekking, cycling, and climbing with their own smart phones. Through practical curriculum operation and project implementation, we show that the proposed curriculum is appropriate to a mobile programming education that combine learning and practice.

The mobile environment which is based on the Internet is expanding the area of the web information systems. The mobile Internet is expanding mobile content and services due to the development of wireless network technology, the proliferation of smart terminal devices, and the emergence of a variety of mobile services platforms. A mobile web is to access to the Internet service using a mobile network or other wireless network using a smart phone or a mobile device. Recently, it is to increase the smart phone usage rapidly in the country, and many companies is entering the mobile market. There are increasing need for this operation plan of a mobile web information system. In this paper, we compared the COBIT, ITIL, the SLA, which are the International Information Systems operation standards, and the information system operation standards of Korea Information Security Agency. We analyzed the suitability of the mobile environment and information system operating instructions, and we compared mobile web, operating environments and the ITIL V3.

Korean prior studies on smart clothing seeking complete mixture of clothing and computer with diverse functions in the ubiquitous environment were so mere, while there have been aggressive activities to develop diverse smart clothing products led by the relevant industries and universities in foreign countries. Given prospective growth of the smart clothing market, there should be customers' evaluation of functions and utility of and sensitivity to smart clothing as well. This study conducted a questionnaire to Korean customers in their twenties regarding their perception and liking of and willingness to use smart clothing, and examined the needs of new functions of smart clothing. As a result, the customers in their twenties turned out to like well-designed and comfortable clothing, and be exposed to diverse and continuous computing environment. Also, they have relatively low perception but considerably high liking of smart clothing, indicating their high willingness to use smart clothing products. They cited 'selectable functions' and 'mobile and convenient ' as merits, and 'too expensive' and 'easy to wash' as demerits of smart clothing. In the respect, they proposed many interesting smart clothing ideas, such as 'clothing with automatic temperature-sensing function, which gets higher heat- insulating function by tightening the textile structure in winter and higher ventilating function by loosening the textile structure in summer.' We hope the results of this study will serve basic data for development of more efficient smart clothing in the future.

This paper presented an augmented reality based mobile application of maintenance and management for concrete bridges. For the development of augmented reality system, it was necessary to establish the concrete bridges detail information and history of maintenance that build the database of those. Also, the augmented reality based system required that concrete bridge information presented by the mobile smart phone. Therefore, this study developed an augmented reality based concrete bridge information mobile application-All about Bridge based on android smart phone and smart pad. The proposed All about Bridge application supports a various bridge informations simultaneously using smart phone and augmented reality technology.
