Purpose: The purpose of this study was to determine the effects of a coordinative locomotor training program on the functional movement screen (FMS) scores of badminton players. Methods: The participants consisted of 31 badminton players who were randomly assigned to either an experimental group (n=15) or a control group (n=16), and engaged in exercise five times per week for six weeks. The experimental group engaged in coordinative locomotor training and the control group engaged in general exercise. An FMS kit (USA) was used to measure the following: FMS score, deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push up, and rotary stability. Results: The FMS score, deep squat, hurdle step, in-line lunge, active straight leg raise, and trunk stability push up showed significant improvement in the experimental group (p<0.05). Conclusion: The coordinative locomotor training program was able to produce confirmation that functional movement screen scores change in the case of effective exercise interventions in badminton players.

Purpose: The purpose of this study was to determine the effects of a functional movement correction exercise on the functional movement screen scores of badminton players. Methods: The participants consisted of 25 badminton players who were randomly assigned to an experimental group (n = 13) or a control group (n = 12); they engaged in exercise three times per week for eight weeks. The experimental group engaged in the functional movement correction exercise, while the control group engaged in general exercise. An FMS kit (USA) was used to measure the following: FMS score, deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push up, and rotary stability. Results: The FMS score, deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, and trunk stability push up, and rotary stability showed significant improvement in the experimental group (p < 0.05). Conclusion: The experiment confirmed that the functional movement screen scores of badminton players improve with effective exercise interventions.

Smart education in the information window, type talent in modern society is changing as talented smart shoes, smart automation creative talent through education, training can be called education revolution. In other words, the advent of smart devices, such as knowledge and information and to actively growing individual customized training paradigm change in the way education and training to reflect this approach. Therefore, in this paper, a smart learning environment based technologies for implementing the system was designed to be the next generation of cloud computing and N screen-based smart education system was studied. From this, educational functions and features in a smart media environment, based on the analysis of the utilization of a smart education system, which maximizes the system design were studied.

이 논문은 멀티프로세싱으로 인해서 발생할 수 있는 touch screen polling I/O 성능 이슈를 다루고 있다. Touch screen이 장착된 휴대용기기가 점차 대중화되고 그 편한 사용성 만큼이나 쉽게 익숙해지고 있다. 하지만, 휴대용기기내에서 여러 가지 작업(multiprocessing or multitasking)을 동시에 처리하면서 생기는 문제들 중에 touch screen의 반응이 의도하지 않은 동작결과로 나타나는 경험을 하게 된다. 이 논문에서 이러한 부분에 집중하여 우선순위가 높은 다른 작업(process or task)과 동시에 touch screen 처리과정을 분석하여 개선책을 제안코자 한다. 또한 우리는 이러한 개선책을 증명하기 위해서 실제 구현을 통해서 확인한다. 개선된 방법은 이 상황과 비슷한 조건에서 활용이 가능할 것으로 판단한다.

최근 진행되고 있는 미디어 융합 환경에서 가장 주목 받고 있는 서비스는 N-스크린 서비스라고 할 수 있다. N-Screen 서비스가 무선 환경뿐만 아니라 이동환경에서도 안정적으로 제공되기 위해서 필요한 핵심 요소기술은 클라우드 컴퓨팅 기술일 것이다. 최근에는 통신 사업자를 비롯한 가전 제조사, 인터넷 및 플랫폼 사업자들이 각자의 강점을 살려서 다양한 클라우드 컴퓨팅 기반의 N-스크린 서비스를 제공하기 시작했고 핵심 서비스로 발전시켜 나가고 있다. 본 논문에서는 클라우드 컴퓨팅과 N-스크린의 관계, 주요사업자들의 서비스 현황 및 발전에 필요한 기술적 요구사항에 대해 알아보겠다.

Employing screen printing technology, aluminum is applied to the back side of the n-type silicon wafer to see the effect of the heat treatment parameters on the Voc of the solar cell, Heat treatment at $850^{\circ}C$ produces the highest Voc among various heat treatment conditions. Heat treatment at the temperatures higher than $850^{\circ}C$ results in lower Voc, which is due to the destruction of the Al-Si alloy emitter layer. The destruction of Al-Si layer observed to be caused by the vigorous movement of silicon atoms toward aluminum layer during the heat treatment.

This paper investigated customers' willingness to pay (WTP) for the integrated news platform, which is a paid digital news service provided by Korean newspapers. The integrated news platform has been widely employed and regarded as an alternative to recover dramatically decreasing sales of newspapers since N-Screen era began. This study employed a conjoint analysis to examine WTP for the integrated news platform and its attributes. According to the results, WPT for the integrated news platform was estimated as 4543.6 won, which is only 30.3% of the real price. Digitalized newspaper and premium news were found to be significant attributes explaining customers' WTP. The results of this paper implies that present marketing strategies for the integrated news platform of Korean newspapers should be reconsidered and revised.

Smart electronics are now widely used in everyday life, but the size of the screen of such devices is still too small to fully enjoy multimedia content. Therefore, if the display is comprised of multiple views produced by multiple smart devices, then the screen output size can increase. However, a time delay between the devices can generate a discordance in the video and sound. This paper compares two synchronization techniques that can be used to minimize such a time delay, and proposes a synchronization technique in which, the timing of the screen for each device is calculated by synchronizing the playback time, using the timing information transferred from the control device, and periodically adjusting the playback timing forward or backward. When multimedia content is reproduced using multiple views from multiple smart devices, we can minimize the time delay, regardless of the network quality or the differences in the devices used for this technique.
