The purpose of study was that the functional gains achieved by stroke patients after rehabilitation in the acute phase have been documented. Sixty stroke inpatients who were at least 3.57 month postonset participated;32 males and 28 females;mean age, 57.4 years. By the classification of diagnosis, 20 subjects were cerebral infarction and 27 subjects were cerebral hemorrhage. Activities of daily living(ADL) performance was investigated using the Klein-Bell ADL Scale. ADL test was practiced within physical therapy room. The outcome variables were first analyzed using frequency statistics. The functional gains of the patients with sex and hemiplegic site were then using an ANOVA. Mean score of dressing, elimination, mobility, bathing/hygiene, eating, and telephone use, 26.6, 56.0, 41.4, 36.5, 82.0, and 56.7. Mean score of total, 43.0. There was no significant difference in sex and hemiplegic site.

Purpose: This study examined the effects of a physical stability exercise program on the functional movement and balance of middle school volleyball players to provide future management and training data to improve the performance of volleyball players. Methods: The subjects were 20 volleyball players from Y Middle School in Mokpo. The results of comparing and analyzing the effects of the physical stability exercise program on the functional movement and balance of middle school volleyball players for 10 weeks are as follows. Results: The number of participants who showed power and agility (p<0.01) was increased significantly, and the response time was shortened significantly (p<0.01). On the evaluation of functional movement, the total score showed a significant difference between the pre-test at 10.90±1.30 points and the post-test at 13.81±.60 (p<0.001). The subjects' balance showed a significant difference from 84.11±7.53 to 97.65±8.47 (p<0.001), and the Right Composite Score showed a significant difference from 83.74±6.64 to 97.27±8.48 (p<0.001). Conclusion: The application of a physical stability exercise program for 10 weeks is effective in improving the speed, agility, functional movement, and balance to volleyball players who are weakened and at risk of injury. This is believed to prevent or reduce injury.

Purpose : The purpose of this study was to investigate the effects of mirror therapy with functional electrical stimulation to improve upper extremity motor function and activities of daily living (ADL) in stroke patients. Method : Thirty patients were randomly assigned to the experimental and control groups 15 patients in each. All subjects received the general occupational therapy consisting of five 30 min sessions per week for 8 weeks, in addition to 30 min of mirror therapy with functional electrical stimulation for the experimental group and 30 min of functional electrical stimulation for the control group for each session. To measure the functions of the upper limb and performance capacities in ADL, the Fugl-Meyer Assessment (FMA), and Manual Function Test (MFT), Modified Barthel Index (MBI) were used before and after the interventions. Results : Both the experimental and control groups showed a statistically significant increase in post-treatment FMA, MFT and MBI scores compared to their pre-treatment scores (p<.05). In addition, intergroup comparisons revealed a statistically significant increase in the scores of all assessments for the experimental group compared to those for the control group (p<.05). Conclusion : Based on these results, it is reasonable to conclude that mirror therapy with functional electrical stimulation is an effective intervention for improving upper limb motor function and ADL performance in stroke patients.

본 논문에서는 한일공동VLBI상관기(Korea-Japan Joint VLBI Correlator, KJJVC)의 핵심 구성시스템인 VLBI상관서브 시스템(VLBI Correlation Subsystem, VCS) 본제품의 1차 성능시험에 대해 기술한다. VCS 본제품의 1차 성능시험의 주요 목적은 현장에 설치하기 전에 제작사에서 다양한 시험항목을 대상으로 시험을 수행하여 문제점을 확인 후 전체 시스템의 완성도를 높이는 것이다. 이번 성능시험에서는 VCS 시작품에서 발견된 FFT 재양자화의 유효비트 부족으로 인한 오버폴로어 문제점을 포함한 기능적인 시험을 수행하였다. 이번 VCS 본제품의 공장시험을 통하여 2008년 VCS 시작품의 성능시험에서 발견한 FFT 의 재양자화 문제점이 완전히 해결되었으며 VCS 본제품에 지연추적, 지연보상, 주파수 묶음 등의 중요 기능도 추가되었다. 그리고 실제 관측 데이터(광대역/협대역)를 이용한 상관처리 시험에서도 예측되는 상관결과가 출력되는 것을 확인하였다.

Testing evaluation is a part of process for design, production, evaluation, operation and abolition, and is the process of certifying system performance. The main purpose of testing evaluation is to reduce the risk factor under the determining process. Testing process has the three step such as design qualification, integration and validation test in factory, system integration and commissioning test. Design Qualification is to verify errors on the design process. Integration and validation test in factory is for the H/W and S/W of an equipment and is to verify interface of subsystem, communication protocol and main functions. System integration and commissioning test is a functional test to adjust successful installation of equipment. According to the testing process, briefly consideration for test item, test method and test contents about signalling system is carried out.

A prototype of Flywheel Energy Storage System with high Tc superconducting bearings was fabricated and tested to verify its applicability for the energy industry. The moment of inertia of assembled wheel with rotor magnets is about 1.072${\times}$10$^{-1}$ Kg-m$^2$. The wheel was designed to withstand its integrity up to the rotation speed of 20,000 rpm. YBCO bulk superconductors prepared by seed growth method were used as bearing to levitate and stabilize the rotating wheel. High speed rotation of the flywheel without mechanical contact was achieved by using specially designed Halbach type motor. The flywheel system showed very high stability during test operation performed up to the speed of about 10,000rpm. The energy loss measured by free decay test performed between 9,300 rpm and 7,000 rpm was calculated as about 45 W.

개발품의 품질을 평가하기 위해 무엇을 어떻게 시험할 것인가 적합한 모델을 정하는 것은 중요하다. 개발된 제품의 대부분의 패키지화된 소프트웨어는 소스코드를 공개하지 않으므로 외부적인 동작 특성을 측정하여 평가한다. 고속철도 선로변 정보처리 기기는 단일계로 구성되어 있던 것을 최근에 2중화하므로 신뢰성을 향상하도록 개발하였다. 철도에 사용되는 용품에 대하여 성능 및 안전성을 확보하기 위하여 철도안전법에서 공인시험기관에서 품질인증을 받을 수 있도록 하고 있어 우선 규정의 적용 가능성을 검토를 하였다. 아울러 정보처리모듈 일반 및 전용 그리고 절체기에 대하여 H/W 와 S/W의 검증을 위하여 필요한 절차와 성능을 확인하는 방안을 검토하고, TFM(Track-side Functional Module) Tester기와 Simulator를 활용하여 보드별 성능시험을 하는 방안에 대하여 고찰하고자 한다.

Objective: The purpose of this study was to compare the effect of ball kicking dual task gait training with the addition of a cognitive task with general treadmill gait training (TGT) on gait speed, gait endurance, functional gait, balance and balance confidence in patients with chronic hemiparetic stroke. Design: Randomized controlled trial. Methods: Fourteen stroke patients who volunteered to participate in this study were randomly divided into two groups with seven patients in each group: ball kicking dual task training (DTT) group and TGT group. The DTT group received ball kicking DTT with cognitive tasks consisted of three stages and the TGT group received TGT using normal walking speed, respectively, for 30 minutes per day 3 days per week for 4 weeks. Outcome assessments were made with the 10-meter walking test (10MWT), 6-minute walking test (6MWT), functional gait assessment (FGA), Berg balance scale (BBS), timed up and go test (TUG), and the activities-specific balance confidence (ABC) scale. Results: The DTT group showed more significant improvement in the 10MWT, 6MWT, FGA, BBS, TUG, and ABC than the TGT group (p<0.05). In addition, within groups comparison showed significant improvement in all variables (p<0.05). Conclusions: The findings suggest that both ball kicking dual task gait training and TGT improve gait performance and balance in patients with chronic hemiparetic stroke. However, ball kicking dual task gait training results showed more favorable outcomes than TGT for chronic hemiparetic stoke patients.

최근 고령 인구의 증가와 건강에 대한 관심으로 운동과 재활이 가능한 기능성 운동기기의 제품 개발을 통해 다양한 삶의 질 향상을 위한 헬스케어 서비스의 고부가가치화가 가속화되고 있다. 본 연구는 기능성 자전거 디자인개발을 위하여 디자인프로세스에 의하여 디자인과 3차의 실험을 진행하였다. 1차 실험은 구조적 측면, 심미적 측면, 기능적 측면, 사용적 측면의 4가지 항목을 조사하였다. 2차 실험에서는 모델링된 10개의 샘플에 대해 10개의 유니버설디자인 항목을 적용하여 전체적으로 평가점수가 고른 분포를 나타내고 있는 샘플(F)을 선정하였다. 3차 실험에서는 1/4 크기의 모형을 제작하여 사용자 서비스 측면의 평가를 진행하였다. 설문항목은 헬스케어 전문가와 협의를 통해 기능성 자전거의 서비스 평가항목 60개의 PPP(product performance program)를 실험하였다. 실험결과, 심미성 요소는 통일성, 비례, 전형성의 항목이 관련 있는 것을 알 수 있었다. 10개 항목(설문 문항 55개)에서는 육체적인 부담의 최소화, 간단하고 직관적인 사용의 항목이 높게 조사되었으며 반대로 정보전달의 배려와 사고와 오작동 방지의 설문 문항이 낮게 나타났다. 앞으로 위의 실험 결과를 좀 더 정확한 측정을 위해 실제 모형이 제작되면 헬스케어 전문가, 디자이너 그리고 고령자를 포함하여 다시 한 번 평가를 진행할 예정이다.
