Glass materials possess unique functional characteristics of ceramics different from those of metals, which has marked glass as one of the mainstay materials in the history of mankind. Nowadays, industrial sophistication necessitates comparable "smart" attributes of glass materials as a significantly advanced form of sophistication. Smart glasses are increasingly applied in many state-of-the-art digital appliances such as displays and semiconductors and waste is also expected to accumulate therefrom in the near future: More than 60,000 tons of smart glass wastes were reported as of 2012, for example. In the present paper, current status of domestic Korean smart glass industry and related recycling enterprise have been comprehensively investigated. Finally, Korean domestic smart glass recycling technology and its future prospect are also briefly presented.

Smart Phones from a PC using the Internet using a multimedia data service provides a scalable and user convenience is provided in the form of an application. Wired and wireless communications, especially with the reduction of royalty free WiFi or the Internet to download the application program on the PC you're using on the Smart Phone. In this paper, the location API in Android-based Smart Phone, using GPS coordinates identified in the latitude and longitude coordinates can be transferred to the server, Android Smart Phone to know the possibility of retracing the location. You are smart trace back information from the user application program design, development, and real-time GPS location signals combined backtrack to read the GPS location in Google Earth application is to study the trace back.

In recently, various kinds of services utilizing the location information of the user's smart phone have appeared. Based on this trend, we designed a new type of learning assistant system that utilizes geofencing technology, which is a field of location information technology. This system identifies the location of the classroom using the location information of learner's the smart phone and automatically provides the necessary learning contents to the learner's smart phone when the learner enters the classroom set as the virtual fence area while carrying the smart phone respectively. Our system provides learning contents in a form similar to the form of a message or a mobile coupon and learners are used to such mobile service environments very much. So the use of learning contents provided by our system is expected to help improve the learning effect of learners.

With the advent of smart media, short and fast-paced video content appeared, and conditions for viewing changed to viewing in environments where the perception is dispersed due to distracting and complicated external situations in a short period of time. Accordingly, smart media videos are quickly delivering meaning while keeping the eyes of viewers who lack patience. Our eyes and brain have a hard time accepting image information that flows through the constraints of a small screen. Our visual perception is limited in terms of acceptable visual information and, in particular, less cognition in moving images, so the production of smart media images should be directed in a way that enhances perceptual understanding. To be able to effectively communicate what you want to talk about while reducing the visual burden, intuitive image comprehension is needed by applying intuitiveness and behavioral induction to the moving images. Close-up shot, stable structure such as frontality and three-division structure, and color have such 'visual affordance' Therefore we need to use that device appropriately.

At the present time it continues to be the smart device released has also been commercialization device accessories accordingly. Such accessories are getting great response to consumers in the form of an external device to a character commercialization design. However, these products are not useful in the functional aspects of using the external form of the device is concentrated only. This study documents the management app to give the game character acts on the application category grouping the ability to efficiently manage the smart device. Research method is to study the existing product released to find out how it works come from the smart device management side, The device app management features added to the game play will be produced based on them.

As credit cards are more convenient than cash of heavy and volume, they are used widely in on_line (internet) and off_line in nowadays. A head of the economically active population had 4.8 credit cards in the third quarter 2011. The economically active population in their 20's and 30's may have more than 10 credit cards. If the membership card and point card are included, the count rise to 20 cards in a man. Therefore, the their purse become thick by several cards. Nowadays, the smart-phone is widely used. Therefore, a lot of credit cards are come in smarty-phone from analog form to digital form. In this paper, we study a method of digital credit cards management in smart-phone. For the method, the hardware need in small and existing system have a few change. All kinds of credit cards are used in smarty-phone. We compare the method with Moneta card and NFC of smarty-phone. The digital credit cards feature a light, safety and convenience of mobile users in several ways.

In this study, a smart bench was developed and researched smart benches that can contribute to user convenience and satisfaction by installing them in parks, bus stops, and tourist attractions in line with the rapidly changing construction of smart cities. The smart bench is automatically operated by the control system according to the external temperature and provides additional functions such as charging, lighting, and advertising to improve general bench functions as well as heating in winter and cooling in summer, making it suitable for smart urbanization. The developed smart bench is designed to be strong enough to withstand loads of about 2,500 N. It minimizes the visible parts such as assembled bolts and 220V power supply wires, It can also give aesthetic effects. The development was carried out with the aim of waterproofing and dustproofing of IP44 grade in accordance with the climate of Republic of Korea, which has four seasons, and it is advantageous for long-term use because the paint was selected for the weather ability (discoloration) grade 3 or higher. If smart bench is commercialized, it is believed that various options can be provided to the smart bench market, where buyers had few product options, as the parts were developed in an assembled type so that all functions can be responded in an optional form according to the installation environment and the buyer's budget.

A Closed-form solution for dynamic response of a functionally graded (FG) nonlocal nanobeam due to action of moving harmonic load is presented in this paper. Due to analyzing in small scale, a nonlocal elasticity theory is utilized. The governing equation and boundary conditions are derived based on the Euler-Bernoulli beam theory and Hamilton's principle. The material properties vary through the thickness direction. The harmonic moving load is modeled by Delta function and the FG nanobeam is simply supported. Using the Laplace transform the dynamic response is obtained. The effect of important parameters such as excitation frequency, the velocity of the moving load, the power index law of FG material and the nonlocal parameter is analyzed. To validate, the results were compared with previous literature, which showed an excellent agreement.

This paper presents a new smart power module for 100[kVA] inverter. In the inverter, the three smart modules are used and those are installed at the each pole of the inverter. Each module receives the switching functions from the inverter main controller, and generates duty ratio for IGBTs' switching of the pole. For the reliable operation of the inverter, CAN communication is used for transferring the switching functions form the main controller to the modules. Experiments verify the performance of the smart power module installed in 100[KVA] inverter.
