Purpose : To identify the effects of Hold-Relax of proprioceptive neuromuscular facilitation (PNF) on the functional improvement of patients with neck myofascial pain syndrome. Methods : The present research investigated 30 patients with neck myofascial syndrome, dividing them into a group doing Hold-Relax of proprioceptive neuromuscular facilitation. This study examined degree of recovery from neck pain by comparing their neck myofascial pain syndrome before and after the treatment, and compared to find difference in the degree of recovery from myofascial pain syndrome. Results : The results are as follows. For the Hold-Relax of proprioceptive neuromuscular facilitation(PNF), the visual analogue scale(VAS) decreased significantly for six weeks treatment, and the range of motion(ROM) of cervical vertebrae increased significantly(p<.05). Conlusion : This study suggest that Hold-Relax of proprioceptive neuromuscular facilitation have an effect on the functional improvement of patients with neck myofascial pain syndrome.

본 논문에서는 재사용 발사체의 종말 연착륙 구간 비행 제어를 위한 컨벡스 최적화 기반 최소 연료 정밀 착륙 문제를 수립하고 이분탐색을 통해 최단 시간 연착륙 비행궤적을 도출하였다. 계산된 유도 명령 추종을 위해 자세 제어 루프와 구동력 분배 문제를 수립하고 해결함으로 재사용 발사체의 착륙 영역 비행제어계 구조를 완성하였다. 완성된 비행제어계의 착륙 유도성능은 6-자유도 시뮬레이션을 통해 구현되고 분석되었다. We formulated the convex optimization based minimum energy soft landing problem for reusable launch vehicles, and obtained the minimum time trajectory via the bisection search. In order to implement the the optimal guidance command and complete the flight control architectures on the soft landing stage, we designed the classical attitude control loops, and formulated and solved the optimal actuator allocation problem. The obtained soft landing guidance performance was analyzed via nonlinear 6-DOF simulation.

Purpose : The main purpose of this study was to investigate the effect on Balance Ability of Knee Osteoarthritis(OA) by Lower Extremity Patterns with dynamic reverse in Proprioceptive Neuromuscular Facilitation(PNF). Methods : The subjects were consisted of 30 women patients with knee OA. All subjects were randomly assigned to PNF group. Each group had a treatment for 30 minutes per day and three times a week during 8 weeks period. Was used to measure recovery or worse of patient's condition, muscle assessment questionnaire(MAQ) was used to measure patient' s muscular strength, Endurance, coordination/balance, KWOMAC was used to pain, stiffness, and physical function, and BPM was used to measure path, anterior-posterior. Results : This study results in following conclusons. 1. MAQ score was significantly decreased in PNF group(p<.05). 2. KWOMAC score was significantly decreased in PNF group(p<.05). 3. BPM were score was significantly decreased in PNF group(p>.05). Conclusion : From this result the PNF treatment retrogression characteristic will be effective in treatment of patient, with the arthritis and widely may be applied at a therapist.
