The present study is to observe changes of health promoting behaviors of obese women by applying 8 weeks of motion-beat on rhythm exercise program. The effects of the obese women's motion-beat in rhythm exercise were summarized in the following conclusions: For changes in their health promoting behaviors, according to the application of motion-beat to the eight-week rhythm exercise, it was noted that the application of motion-beat was effective in the factor of stress management. Therefore, since the exercise applying motion-beat maximizes fun and interest, it has been developed as a program on sports for all, appropriate and efficient for obese women, and it is expected that positive changes in health promoting behaviors can be suggested as a measure for the facilitation of their continuous participation in the exercise.

In Twitter, a user can post a message below 140 characters on his/her account, and can also repost a message of other users who the user follows. The message posted by the user in turn can be seen and reposted by other users who follow the user, which is called Re-tweet (RT). While some messages spread widely, other messages have relatively less or no RT. What factors cause these quantity variances of RT originated from original messages? How can the messages become influential in online social networks? As an effort to answer the above questions, we focused on information vividness, message characteristics, and originator characteristics. In perspective of managerial implication, we expect that the findings of this paper will provide corporations with helpful insight on the Word-of-Mouth (WOM) effect for efficient and effective advertisements and communications when they send a message of new products or services through Social Network Services. In perspective of academic implication, we identify the effect of contents of a message on WOM, which has been dealt with by few social network researches.

This study suggests a technique to implement the production of animation by blending between key frame animation and motion capture animation through short animation 'Drip.' It reduced the time taken to produce an animation by not only enabling efficient process management through mutual organic connection but also conducting a process of mutually making up for weak points of key frame animation and motion capture animation. Through this, it was intended to be helpful in efficient animation production by overcoming the limitation of key frame animation and motion capture animation and perceiving and applying a complex process.

본 논문에서는 코드 최적화를 위하여 계산적으로나 수명적으로 제한이 없는 희소 코드 모션 알고리즘을 제안한다. 이 알고리즘은 지나친 레지스터의 사용을 막기 위하여 불필요한 코드 모션을 억제한다. 또한, 본 논문에서는 기존 알고리즘의 술어의 의미가 명확하지 않은 것을 개선하였고 노드 단위 분석과 명령어 단위 분석을 혼용했기 때문에 발생하는 모호함도 개선하였다. 따라서, 제안한 알고리즘은 불필요하게 중복된 수식이나 배정문의 수행을 피하게 함으로써, 프로그램의 불필요한 재계산이나 재실행을 하지 않게 하여 프로그램의 능률 및 실행시간을 향상시킨다.

본 연구는 립모션을 통해 피아노교육을 제공함과 동시에 알맞은 운지법을 제안한다. 기존의 피아노 교육 프로그램은 운지법을 제공하지 않아 피아노를 한 번도 접해보지 못한 사람들은 제대로 된 기초를 배우지 못했다. 따라서 본 논문에서는 알맞은 운지법을 제안하고, 립모션과 컴퓨터가 실행되는 환경 어디에서든 프로그램을 실행 할 수 있도록 하였다.

In this paper, a register allocation techlique that translates memory accesses to register accesses Is presented to enhance embedded software performance. In the proposed method, a source code is profiled to generate a memory trace. From the profiling results, target functions with high dynamic call counts are selected, and the proposed register allocation technique is applied only to the target functions to save the compilation time. The memory trace of the target functions is searched for the memory accesses that result in cycle count reduction when replaced by register accesses, and they are translated to register accesses by modifying the intermediate code and allocating Promotion registers. The experiments where the performance is measured in terms of the cycle count on MediaBench and DSPstone benchmark programs show that the proposed method increases the performance by 14% and 18% on the average for ARM and MCORE, respectively.

This paper addresses the design and implementation of an Android application for real-time precise motion control. To provide stable real-time performance, we implemented the application in two parts: Android service in the form of a daemon process, which periodically transfers a set of position commands for all motors through a real-time fieldbus, and Android UI application, which generates and delivers the set of position commands to the Android service. To support such a real-time motion control application, we use multi-core partitioning, which partitions the processor cores into a real-time partition to be used by the real-time motion control service and a non-real-time partition to be used by the Android application, and set up a shared buffer between them for communication. Our experiments show that we can obtain a motion control period of 2 ms with 99% task activation jitters less than ${\pm}55{\mu}s$ for a configuration where each of the four threads controls two motors in a group.
