Modern trams with a super capacitor have gained a lot of attention in recent years due to its reliability, convenience, energy conservation and environmental friendliness. Because of its special charging characteristic, the traditional charging structure and control strategy cannot satisfy its charging requirements. This paper presents a new charging topology for fast charging modern trams with a super capacitor and it designs a controller using continuous control set model predictive control (CCS-MPC). There are three contributions in this paper. First, a new charging structure is designed and its mathematics model is derived. The cascade structure is adopted instead of the parallel structure to simplify the control process and to keep the rated power of the controllable part low. Second, a MPC control strategy is proposed to satisfy the charging characteristic. The optimal control signal can be obtained by solving the designed optimization problem. The optimal control signal is related to the discrete control action. In addition, mapping between the continuous control signal and the discrete control action is designed. Third, a semi-physical experimental platform is built to verify the proposed topology and control method. The simulation model and experiment platform are built to verify the correctness of the new structure and its control method. The results obtained show that the new topology can work effectively.

PURPOSE: The purpose of this study was to determine the effect of action observation with observation type on the limits of stability and dynamic gait ability in stroke patients. METHODS: The 20 stroke patients who participated in this study were randomly divided into two experimental groups who underwent training three times a week for 4 weeks. Their balance was tested as the limit of stability with Biorescue. Their Dynamic gait ability was tested with the Dynamic Gait Index (DGI) before the intervention, and after 4 weeks. Independent and paired t-tests were used to analyze the results. RESULTS: The results confirmed the limit of stability on the moving areas of the paralyzed and non-paralyzed sides. The limit of stability and dynamic gait index measurements confirmed that the moving area showed a significant difference after the intervention in the whole movement observation group (p<.05), but the partial movement observation group showed no significant difference (p>.05). A significant difference was also noted for the comparison between the both groups after the interventions (p<.05). The functional walking ability showed a significant difference when compared to the ability before the intervention, as determined by the changes in scores obtained for the dynamic gait index (p<.05). CONCLUSION: Interventions utilizing whole movement confirm that training improves stability and functional walking ability in stroke patients with disabilities in balance and walking ability.

강량원 연출의 공연들에서는 배우들의 신체행동연기는 대부분 단순하고 반복적이다. 이러한 연기는 관객의 감각적 지각을 유도하면서 관객에게 특정한 육체적 감정을 갖게 하는 효과를 거둔다. 대사가 주는 기호적 의미에 더해서 관객의 감각에 직접적으로 자극을 줌으로써 관객은 무대공간에서 만들어지는 분위기에 힘입어 수행적 공간의 조성에 동참하게 되며, 따라서 자동형성적 피드백-고리가 만들어지고, 의식된 지각의 도움으로 의미의 창발을 경험하게 된다. 창발적 의미는 상상, 회상, 연상 등에 의해서 불쑥 솟아오르는 것이며, 이는 결코 의도적으로 생산된 것이 아니다. 그리고 관객은 재현적 지각과 현존적 지각의 교차에 힘입어 공연에 함께 동참하는 가운데, 특히 신체행동연기의 현존성의 영향을 받게 된다. 본고에서는 2010년대 이후에 공연된 극단 동의 주요 공연 네 편에 대한 연구를 통해서 각각의 공연이 가진 개별성뿐 아니라 전체 공연을 아우르는 공통성 역시 확인하였다. 이로써 강량원과 극단 동의 연극미학이 가진 변별력을 발견하게 되었다.

Interpretation of pain by the patients and the observers as well as the methods of treatment remain as varied as are the concepts of pain. The physiologic mechanism of pain is undergoing a serious revision. It is nociceptive receptive mechanism and Melzak concept of gate theory of pain transmission and etc. Therefore pain depend on the evaluator's learning, experience, or specialty.

Background: Improvement of the lumbo-pelvic stability can reduce the compensatory action of the erector spinae (ES) during prone hip extension (PHE). Furthermore, the application of abdominal drawing-in (ADI) maneuver increases the action of gluteus maximus (GM) and decreases the action of ES during PHE by improving the lumbo-pelvic stability. However, the post-ADI exercise effects on PHE, not the real-time application of ADI maneuver, has not been studied. Objects: This study is aimed at investigating the post-ADI exercise effects on the muscle activities of GM and ES during PHE. Methods: A total of 24 female adults participated in the study, and they were divided into two groups: Those with normal abdominal muscles ($n_1=12$) and those with weak abdominal muscles (WA) ($n_2=12$). Before the intervention, the subjects' GM and ES muscle activities during PHE were measured. Subsequently, the two groups were asked to perform the ADI exercise for 10 minutes. After the ADI exercise, the GM and ES activities were equally measured during PHE. Results: The comparison result of the ES muscle activities before intervention shows a significant difference between the two groups (p<.05); the WA group showed higher muscle activities than the normal group. For the within-group comparison, the muscle activities of the ES in the WA group significantly decreased after the ADI exercise (p<.05). For the GM muscle activity, no significant difference was observed in all comparisons (p>.05). For the changes in muscle activities before and after the ADI exercise, a significant difference exists between the two groups only for the changes in ES activities (p<.05); WA group exhibits higher changes than the normal group. By contrast, no significant difference exists between the two groups for the changes in GM activities (p>.05). Conclusion: After the ADI exercise, the compensatory action of ES in the female adults with WC is implied to decrease during PHE.

Purpose: The purpose of this study was to describe the movement patterns when lying from an erect stance to a supine position of healthy adults and hemiplegia patients in the age group from 50 to 70. Methods: The subjects used in this study were 230 patients (144 healthy adults and 86 hemiplegia patients). Movement patterns were classified using categorical descriptions of the action of three body regions: the upper extremity, lower extremity, and the head-trunk region. Results: In the most common supine lying position in healthy adults (29.7%), the female fifties age group performed a symmetrical pattern using the upper extremity region, a symmetrical squat pattern using the lower extremity region, and a symmetrical pattern using the head-trunk region (1-1-1). However, in the most supine lying position in hemiplegia patients (32.0%), the female sixties age group usually performed this pattern by using the upper extremity and lower extremity regions in a squat position by raising the leg, and performing rotation of the head-trunk region (3-4-3). Conclusion: Using this clinical therapy, and considering the patients ability to exercise when lying from an erect stance to a supine position, the proper care could be provided. Moreover, this therapy introduces action based on a variety of training methods and on the effects which might result from any changes.
