The aim of this study was to compare the duration of hamstring flexibility improvement after 3 stretching interventions in people with limited hamstring flexibility. Twenty-two subjects (12 men, 10 women) with limited hamstring flexibility of the dominant leg received 3 stretching interventions- modified dynamic stretching (MDS), hold-relax (HR), and static stretching (SS)-in a random order. All the subjects received all 3 interventions at intervals of at least 24 hours to minimize any carry-over effect. Modified dynamic stretching was applied as a closed kinetic chain exercise in the supine position by using the sling suspension system (Redcord Trainer(R)). The SS and HR interventions were individually performed in the straight leg raising (SLR) position, and all 3 interventions were performed for 3 minutes. Outcome measures included passive knee extension (PKE) measurements. Five post-test measurements were recorded for all subjects at 3, 6, 9, 15, and 30 minutes after the interventions. MDS was associated with a significant increase in knee extension range of motion even at 30 minutes post-treatment. In contrast, the HR and SS stretching methods showed increased hamstring flexibility for only 6 minutes post-treatment. Improvements in the range of motion of knee extension (indicating enhancement in hamstring flexibility) with MDS were maintained longer than those with the HR and SS interventions. Therefore, MDS may be more effective than the other interventions for maintaining hamstring flexibility.

1. Objectives It is necessary to find the psychological methods to treat not only physical but also mental problems. Because the Sasang Constitutional medicine is based on Mind-Body Medicine, so that the Nature and Emotion-Happiness, Anger, Sorrow, Pleasantness- have to be controlled properly. 2. Methods We analysed the characters of each constitutions, drama therapy and meditation and tried to find the suitable application of one for Sasangin. 3. Results and Conclusions Soeumin is feminine, easy to worry, pessimistic and non-active so they need to express their problems, be encouraged and participate to be one of a group having relationship with other people. Soyangin is out-going, easy to start, not enough to be aware of themselves so they need to relax, calm and try to have an insight into themselves. Taeumin is stable, easy to keep something so they need to communicate well with the exterior. Taeyangin is going forward, masculine and necessary to avoid being angry so they need to calm down and relax. Drama therapy is group work with actors, staffs and audiences so it is useful to express their negative feelings through motions, dances and sounds unless they talk. So it is supposed to be useful far Soeumin and Taeumin. And we can apply it to heal the Emotion because it is based on the relationship and the contact with other people. Meditation is helpful to not only concentrate, relax, have insight into themselves but also calm down anxiety, depression an anger. So it could be the best psychotherapy for Soyangin and Taeyangin. And we can apply it to reflect oneself alone to express their Nature adequately.

Purpose : The purpose of this study was to compare the influence of Contract-Relax Technique of PNF(Proprioceptive Neuromuscular Facilitation) and taping treatment on the ROM(Range of Motion), pain and gait speed of osteoarthrits of knee. Methods : In this study K hall for the aged were selected. Twenty-six subjects with osteoarthrits participated in the experiment. The subjects were partitioned into two groups are 13person PNF group and 13person taping group. All subjects randomly assigned to the PNF treatment group and taping treatment group. Both group received treatment for 3times a week during 4 weeks. (PNF group received treatment for twenty times at once). Algometer and VAS(Visual Analogue Scale) were used to measure pain, the ROM was meaured using goniometer and gait speed was measured using a stopwatch (30m-test). All measurements of each subject were measured at pre-treatment and post-treatment. The data were analyzed with SPSS WIN 11.5 using t-test. Results : The PNF group had a significantly increase of knee extension ROM and significantly decrease of pain after treatment 4 weeks(P<0.05). The taping group had a significantly increase of knee extension ROM and gait speed and significantly decrease of pain after treatment 4 weeks(P<0.05). Conclusion : These data suggests that PNF is beneficial to increase knee extension ROM and to decrease pain. Taping is beneficial to increase knee extension ROM and gait speed and to decrease of pain.

본 논문에서는 유도탄 조우 시나리오를 고려한 W-대역 밀리미터파 탐색기의 지상 표적 식별을 위한 1차원 산란점 추출 기법을 소개하고, 편파 방향 및 조우 각도에 따른 산란점 추출 결과를 비교 분석하고자 한다. CST A-Solver를 이용해서 SBR(Shotting Bounce Racing)기법을 통해서 전차 표적의 표면과 모서리에 의한 산란을 각각 계산하였다. 편파에 따라 4-채널 RCS 데이터에 대해서 스펙트럼 추정 기법(spectral estimation technique)인 1차원 RELAX 알고리즘을 사용해서 각각의 산란점(scattering center)을 추출했고, 편파 방향과 관측 각도의 변화에 따른 산란점 추출 결과를 비교 분석하였다. 시뮬레이션 분석을 통해서 지상 표적에 대한 산란점 추출 결과를 W-대역 밀리미터파 탐색기의 표적 식별을 위한 특성 벡터로 활용 가능함을 확인하였다.

차량용 레이더(automotive radar)는 크기, 무게, 비용 등의 문제로 적은 수의 수신 채널을 가진 안테나를 사용한다. 이때, 스펙트럼 추정 기법 중 하나인 relaxation(RELAX) 기법을 이용하면, 표적의 방위각뿐만 아니라, 빔 내에 존재하는 표적의 개수 추정 또한, 가능하다. 하지만, 차량용 레이더의 적은 수신 채널 개수로 인하여, 정밀하지 않은 각도 영역에서의 스펙트럼 추정이 이루어지며, 이는 부정확한 방위각 추정 성능을 야기한다. 이를 개선하기 위해 본 논문에서는 minimum length description(MDL) 기준을 통한 표적 개수의 추정과 결부한 root-multiple signal classification(root-MUSIC) 기법을 이용하여 표적의 정확한 방위각을 추정하도록 제안한다. 시뮬레이션에서는 세 점 표적들이 안테나 빔 내에 존재할 때, 제안한 방법이 더 나은 방위각 추정 결과를 도출할 수 있음을 보인다.

Objective: This study investigated the effects of combining both mobilization and hold-relax (HR) technique on the function of post-surgical patients with shoulder adhesive capsulitis. Design: Randomized controlled trial. Methods: Forty-five surgical patients with shoulder adhesive capsulitis participated in this study and were randomly divided into three groups; both mobilization with movement (MWM) and HR technique (HR-MWM) group (n=15), the MWM group (n=15), and control group (n=15). All participants received three different interventions; 1) MWM combined with HR technique in PNF stretching on the shoulder, 2) MWM on the shoulder, 3) general physical therapy and intervention with neither MWM or HR stretching. Pre- and post-intervention, each subject was randomly evaluated for shoulder flexion range of motion (ROM), shoulder flexor muscle strength, Visual Analogue Scale (VAS), and the Korean version of the Shoulder Pain And Disability Index (SPADI). Results: The MWM combined with HR technique group had significant effects on shoulder flexion ROM, shoulder flexor muscle strength, VAS and SPADI compared to the MWM and control group (p<0.05). The MWM group showed a significantly greater increase in shoulder flexion ROM compared to the control group (p<0.05). Conclusions: These findings suggest that combining both the MWM and HR technique on the shoulder may more effectively improve shoulder function than MWM alone or without MWM&HR technique. Therefore, combining both the MWM and HR technique is a suggested intervention for increasing function due to shoulder adhesive capsulitis after surgery.
