전세계적으로 스마트폰, 스마트패드 등의 모바일기기의 사용은 빠르게 확산되고 있으며, 모바일 환경에서 제공되고 있는 웹 서비스 시장도 급변하고 있다. 특히, 모바일 환경에서는"Any time, Any where" 특성에 따라 사용자의 빠른 피드백이 가능하게 되었으며 이에 따라 서비스 운영 업체는 사용자의 빠른 피드백에 대한 신속한 대응이 요구되고 있다. 이러한 웹 서비스 시장의 변화는 기존의 서비스 개발과 운영 프로세스간의 단절적인 관점을 통합적인 관점으로 변화시키고 있다. 이에 본 논문에서는 모바일 기기 환경에서 제공하고 있는 웹 서비스에 대한 다양한 관점에서 잦은 개선 요청에 대한 피드백에 신속하고 정확하게 대응하기 위한 통합적인 프로세스를 제안한다. 제안된 프로세스는 ITIL 운영 모델 내에 개발/테스트 프로세스를 통합하고 있으며, CMMI-SVC 모델에 적용하여 이전보다 더 많은 프로세스영역에서 충족하고 있음을 보여주고 있다.

EMSCT (Electrical Muscle Stimulation Conductive Textile) is an electrical muscle stimulation pad that can compensate for ease of use and comfort, which are disadvantages of conventional hydrogel pads used in electrical muscle stimulation (EMS). With the concentration with SWCNT (Single-Walled Carbon Nanotube) and the number of impregnation processes, EMSCT was tested by giving conductivity to five fabrics (radirons, neoprene, spandex cushions, poly100%, and vergamo). The padding process with SWCNT was performed, and the alternating current measurement indicated that the most similar alternating current with hydrogel was the Vergamo fabric of SWCNT:=2:1. Furthermore, the usability evaluation of convenience, usability, and psychological satisfaction results in increased usability of EMSCT compared with conventional hydrogel pads.

The Next-generation IT technology has been evolving from single technique to another which has merged, converging characteristics. The government categorized the 5 essential technologies to secure competitiveness in designing system semiconductors as smart motor vehicle info-tainment platform, smart TV multimedia system, smart phone analog interface technique, smart convergence digital communication and RF techniques, and advanced power management for smart devices. Also, it designated smart phone, smart TV, smart motor vehicle, and smart pad as the key industries. Such core techniques will become the key technologies of semiconductor design to secure the competitiveness of the next generation smart devices and the techniques can be transferred to fab-less design companies. In this contribution, we analyze the issues and the problems of the SoC design trends for smart motor vehicle info-tainment platforms.

The purpose of this paper is to review recent articles on applying smart learning for elementary students with learning disabilities. The search procedures through the Web-database system were implemented to find the proper research. Finally, a total of 10 articles met the criteria and were included in this review. Each study was analyzed according to the categories of the population, setting, research design, and intervention. The results indicated that research design implemented as case study and single subject design. Results founded strategies applying smart learning leaned too much towards using the skill-based application as learning contents. Based on analysis results, considerations for smart learning for elementary students with learning disabilities were suggested.

Mobile devices like iphone, ipad, kindle, and PDA are used as everyday tool. In the mobile environment, smart phones and other mobile units are also used as a tool for protection or infringement of personal information. Therefore, smart monitoring technology is required to protect personal information and privacy. On the other hand, with smart phones and the mobile environment, diverse application technologies are realized on hardware and software platforms. Therefore, this paper designs the network structure that forms privacy trust zone, and based on this, deals with the monitoring and monitoring prevention system with a focus on CCTV, through which this paper proposes a system that provides privacy trust zone information and its utilization which is capable of smart monitoring.

Smart phones provide variety of functions like world processing, chatting, web browsing, etc. for users. Therefore, efficiency of the keypad that are used in text entry are becoming more important. But, in traditional english mobile keypad, text entry speed is not efficient because simple placement of characters in accordance with the order of characters. In this paper, we propose the improved english keypad for smart phone using the frequency information of english characters and bigram. And, we verified that the proposed keypad is more efficient than other keypads through the experiment.

Smart devices such as smart phones, smart TVs, and smart pads have become essential devices in recent years. As the popularity and demand grows, the performance of smart devices is also getting better and users are dealing with a lot of things such as education and business using smart devices instead of desktop. However, smart devices that still have poor performance compared to desktop, even with improved performance, have difficulty running high performance applications due to limited resources. In this paper, we propose a load balancing algorithm applying the characteristics of smart devices to overcome the resource limitations of devices. in order to verify the algorithm, we implemented the algorithm after adding the distributed processing system service in Android platform. After constructing the cluster on the smart device, various experiments were conducted. Through the analysis of the test results, it is confirmed that the proposed algorithm efficiently improves the overall distributed processing performance by effectively aggregating different amounts of computing resources in heterogeneous smart devices.

Smartphones and smartpads have a lot of advantages such as high convenience and portability. Also, they can effectively manage enormous amounts of information based on their high performance and plentiful applications. As such devices have been frequently used, many users manage various types of information using the devices. Recently, during conferences or seminars, smart device users often try to utilize stored resources on their devices and present them visually. Unfortunately, since smart devices have small displays, there is an essential difficulty in visual sharing of information. In this paper, we propose a method which integrates screens of several android smart devices and supports sharing of the integrated screen through a large display, presenting a screen sharing system for android smart devices. The developed system integrates display screens of several smart devices into a screen and shows the integrated screen through a large display connected to a desktop computer. In addition, to support the effective sharing of screens, the system provides functions for adjusting the number and the size of screens on a large display. The functions are controlled on a smart device and/or a desktop computer.

In this paper, we proposed a system and a scenario to raise efficiency of gas safety management by developing wireless ZigBee communication modules, smart-home gas safety appliances and the system suitable for gas safety. Our designed system consists of a micom gas meter, an automatic extinguisher, sensors, and a wall-pad. A micom-gas-meter monitors gas flow, gas pressure, and earthquake. An automatic fire extinguisher checks combustible gas leaks and temperature of $100^{\circ}C$(cut off) and $130^{\circ}C$(fire). Sensors measure smoke and CO gas. In our novel system, a micom-gas meter cut off inner valve with warnings, an automatic fire extinguisher cut off middle valve and spray extinguishing materials, and sensors generate signals when detecting smoke and CO and then take a next action. Gas safety appliances and sensors automatically takes measures, and transmit those information to a wall-pad. The wall-pad again transmits real time information to server. Users can check and manage gas safety situations by connecting BcN server through web or mobile application. We hereby devised scenarios for gas safety and risk management based on the smart, and demonstrated their efficiency through test applied to filed.
