Console game has high market occupancy in the world game market and has popular favor for many players. Especially, the experience console game in which body movement is used to control the game has made its own market. However, previous experience console games can easily make players to be boring and require additional payments to update the game. In this paper, we present an experience dance game using Kinet, which has high interest and can be continuously updated. Differently from previous console games, the presented game makes the player to see how they are playing and to know what the next action is. Also, the accuracy of the player motion is compared 20 times in each second to get high interests of players. Through these functions, the presented game can achieve high satisfaction rates based on the qualitative evaluation of users.

The aim of this study was to determine the effects of the action observation and visual feedback on the alignment, pain and function of forward head posture(FHP) and round shoulder(RS). A total of 24 participants with FHP and RSP were randomly assigned to general exercise(GE, n=8), action observation(AO, n=8), and visual feedback(VF, n=8). All subjects were exercised three times a week for four weeks. The groups were assessed for craniovertebral angle(CVA), round shoulder posture(RSP), visual analog scale(VAS), and neck disability index(NDI) before and after exercise, There was a significant difference in CVA in the GE, AO and RSP, VAS and NDI were significantly different in all groups. AO was more effective than GE, VF for VAS. The results of this study suggest that action observation may be effective to improve the FHP and RS.

This research analyzed the cognitive factors affecting stroke patient's activity of daily living performance and suggests the approaches which can contribute to the effective activity of daily living performance in the rehabilitation treatment of stroke patients. In this study, Seoul Computerized NeuroCognitive Function Test (SCNT) and MBI have been performed for 21 patients under extensive rehabilitation treatments, hospitalized in the rehabilitation clinic of A hospital after being diagnosed as a stroke caused by cerebrovascular disorders. To assess the effectiveness of the cognitive factors which affect the stroke patient's activity of daily living performance, activity of daily living performance values were set as dependent variables and 10 cognitive factors were included in the model to carry out analysis of the multiple regression analysis. The results show that stroke patient's activity of daily living performance have statistically significant correlations with divided attention, motor control and selectivir attention. In addition, cognitive factors explained 69.8% of the stroke patient's activity of daily living performance. Consequently, if divided attention and motor control are considered as a focal point of training in the rehabilitation treatment of stroke patients, we can effectively promote the improvement of the activity of daily living performanceroutine activities.

The study aimed firstly, to develop the women's bodysuit sleeve block construction method adopting the appropriate pattern reduction rates according to the fabric stretch property. Secondly, the details applied to the bodysuit sleeve block drafting (Dr the educational and industrial usage were proposed. For these, several distinguishing bodysuit sleeve pattern making methods(i.e. Joseph-Armstrong: T1, Shoben & Ward: T2, Esmod: T3 and Mixed Joseph-Armstrong: T4) were analyzed and divided into two categories that adopt 1) the equally (i.e., T1) and 2) the differently(i.e., T2, T3 & T4) distributed front and back armhole length measurements. Women's sleeve samples were made for the research using the same stretch fabric($50\%\;and\; 70\%$ in wale and course each) to the previous research. A group comprising 5 relevant experts evaluated the fit and comfort features of the samples. Experiments analyzed the appearance of sleeve samples focused on total 13 evaluation parts(including the front/side/back fit tolerance, sleeve centre line, sleeve length, appropriateness of the sleeve appearance balanced with the bodysuit and etc.): and performed the comfort test evaluating three kinds(vertical-front/vertical-side/ horizontal) of arm movements. The most appropriate bodysuit sleeve to fulfil the original aims of the study was suggested. The findings and suggestions throughout the study were: 1) the measurements and required reduction rates for the bodysuit sleeve block developed: outer sleeve length (with 1.0 RR), crown height(with 0.7 RR), front and back armhole lengths measured on the bodysuit blocks ($0\%$ ease amount), elbow width(0.9/0.95 RR), wrist girth measurements(from $12\%\;to\;18\%$ tolerances can be given to): and 2) the differently distributed front and back armhole length measurements resulted in the better fit and comfort through the research.

In this paper, a new design of a planar rectenna system and its application to a wake-up receiver operating for incoming signal with a specified frequency are proposed for low-power sensor system applications. The planar and integrable rectenna system is designed with DGSs(Defected Ground Structures) at 2.4 GHz. The DGSs reject harmonic components of 4.8 and 7.2 GHz and eliminate 2.4 GHz fundamental frequency for DC-path filtering. The rectenna system has been evaluated for the conversion output voltages, and applied to the switching of a power supply at the low-power sensor receivers. The proposed system has been evaluated for the wake-up performance by testing a lownoise amplifier operation. From the experimental results, the proposed receiver system presents excellent operation performances.

Objective : This study aimed to investigate the effects of home-based action observation training on upper extremity in brain tumor patient. Methods : Among the single case study design, this experiment used ABA' design. The evaluations were carried out 4 times during pre baseline period(A) and post baseline period(A') respectively. At the intervention period(B), a total of 25 times of action observation training and 10 times of evaluation were administered. Results : Study results indicate that 9-hole peg test, Box and Block Test, Manual Function Test were increased when compared to action observation intervention(B) to pre intervention baseline(A). Conclusion : Based on these results, home-based action observation training may be an effective upper extremity intervention strategy for tumor-induced hemiparetic patient.

VR content manipulation equipment is not easy for individuals to access because it requires high prices. Especially, in the case of a system for tracking the motion of the user among the VR contents, a separate optical sensor device using an infrared camera is generally used. The disadvantage of the optical sensor equipment is that the measurable range is dependent on the measurement direction when tracking the rotation motion when using only a single device. In order to solve the above problems, this paper shows that the inertial sensor of the smartphone, which is generally owned by the public, can track the rotational motion of the user regardless of the measurement direction . The system using the LeapMotion is used as the reference system, and the system using the smart phone is defined as the evaluation system, and the usability of the evaluation system is verified by comparing the user satisfaction of the two systems.

본 논문에서는 ATM망상의 다수의 종단간(End-to-end) 연결에서 망의 구성장치인 교환기들 간의 상호연동성능에 관하여 평가하였다. ATM Forum의 Traffic Management Specification 4.0에서 제시한 스위치 메커니즘 중에는 Binary Feedback 기법과 Explicit Rate Feedback 기법과 Explicit Rate Feedback 기법이 있다. 전자의 경우에는 망으로부터의 궤환정보를 이용하여 종단시스템에서 트래픽 제어가 이루어지나, 후자의 경우에는 스위치로부터의 정보에 의하여 종단시스템의 전송 가능한 트래픽 양이 정해진다. 상이한 방식으로 동작하는 교환기로 구성된 망에서는 그 제어방식의 차이로 동일한 방식을 가지는 교환기들로 구성된 종단간 연결과 비교할 때 망자원의 활용도, 망 제어 측면에서 성능저하를 예상할 수 있다. 이에 본 논문에서는 4가지의 기법에 대하여 각각 망을 구성하고, 구성의 차이에 따른 성능을 비교하고 그 원인을 분석하였다. 상이한 방식들로 구성된 경우 각 구성형태에 따라서 성능 차이가 나타났으며, 폭주가 발생하는 노드의 교환기 동작성능이 전체 망 전송성능을 결정하는 것을 볼 수 있었다.
