Purpose : In order to investigate the effects of balance training on patients with degenerative arthritis. Methods : 30 participants aged 60 or older participated in balance training for an 8-week period. The effects of the balance training were measured by the visual analog scale(VAS) and static and dynamic balancing. The following are the results of the study. Results : There were no statistically significant differences in measurements of pain when control group participants were at rest and while walking as measured by VAS, but there were statistically significant reductions for the experiment group. Within the control group, there were no statistically significant differences between pretest and posttest results for opened and closed-eye static balance index and visual dynamic balance index. However, within the experiment group, there were statistically significant differences between pretest and posttest results for opened and closed-eye static and dynamic balance indices. Conclusion : The results above provide evidence that balance training effects pain and balance of patients with osteoarthritis and aids in functional movement.

김찬규,Kim Chan-Kyu 한국통신학회 2006 韓國通信學會論文誌 Vol.31 No.8A

이 논문에서는 다중 사용자 환경에서 MIMO(Multi-Input Multi-Out)-OFDM(Orthogonal Frequency Division Multiplexing)시스템의 성능 향상을 위해 빔 형성기와 결합된 space-time decoder를 가진 새로운 시스템 구조와 이 구조에 적합한 적응 빔 형성기법을 제안한다. MIMO-OFDM시스템에서 Nr 개의 안테나를 가진 수신기에 송신안테나 수(Nt)와 동일한 수의 빔 형성기를 설치함으로서 이 빔 형성기에 의해 CCI(cochannel interference)가 제거된 Nt개의 신호들이 출력되고 출력된 신호들은 space-time decoding 되어 diversity 이득을 얻을 수 있다. 따라서 CCI가 있는 다중 사용자 환경에서 제안된 MIMO-OFDM 시스템의 성능은 크게 향상된다. MIMO-OFDM 시스템에 제안된 적응 빔 형성기법과 결합된 S-T coding기법을 적용할 경우 수렴특성과 성능 개선 효과를 모의 실험을 통하여 확인한다. In this paper, the new technique combining beamforming with space-time coding is proposed for an orthogonal frequency division multiplexing(OFDM) system with multi-input multi-output(MIMO). When MIMO-OFDM system is employing Nt(the number of transmitterantenna) beamfomers and one S-T decoder at Nr receiver antennas, Nt signals removed CCI are outputted at the beamformer and then diversity gain can be got through space-time decoding. As the proposed technique can reduce cochannel interference and get diversity gain in the multi-user environment, the performance of MIMO-OFDM system is very improved. BER performance improvement and convergence behavior of the proposed approach are investigated through computer simulation by applying it to MIMO-OFDM system in the multi-user environment.

The purpose of this study is to find out the influence of Physical Therapists' heavy work on their cervical spines. Subjects were 80 members of Physical Therapists, 40 males and 40 females who were between 3rd decades to 4th decades. The Cervcial Range of Motion instrument was used to measure six cervical range of motion such as flexion, extension, left and right lateral flexion, left and right rotation. The degree of rotation and both lateral flexion was appeared as decrement in 4th decades than 3rd decades(P<0.05). And the left lateral flexion in female Physical therapiest was increased than in male ones(P<0.05). By this results, it was proved that the older the PT's age, the less the cervical motion range and there were more decrement in male Physical Therapists than female Physical Therapists. And finally I think that the evaluating method used in this study will be clinically very useful and be a basic raw materials for evaluating the existence and the degree of functional disability as in the occupational hazards due to Physical Therapist's heavy work.

이 연구는 심박수, 수축기 혈압, 이완기 혈압, 말초혈관 산소포화도 알아보고자 바닥과 스위스 볼상에서 요부안정화운동(LSE)에 따른 심혈관기능에 미치는 연구를 하였다. 대상자는 K 산업체 재활센타를 이용한 근골격계 근로자 중 선정기준에 적합한 남성 18명을 실험1군 바닥 적용군에 9명, 실험군 2군 스위스볼 적용군에 9명으로 분류하여 심박수, 수축기 혈압, 이완기 혈압, 말초혈관 산소포화도를 비교하였다. 심박수는 휴대용 심박 측정계(RS400sd, Finland)로, 혈압은 혈압계((FC-110, Japan)로, 말초혈관 산소포화도는 누리텍 체력 측정장치((TF-300-5, Korea)로 측정하고 분석하였다. 두군 모두 운동실시 후에 말초혈관 산소농도가 점차 통계학적으로 유의하게 증가하였으며, 수축기혈압이 통계학적으로 유의하게 감소하였다. 요부안정화운동에 따른 자세변동이 심혈관기능에 영향을 미치지만 지면의 상태에 따른 차이는 크게 영향을 받지 않는다는 결론을 얻었다. This study conducted the following experiment to examine effects of cardiovascular function on lumbar stabilization exercise(LSE) in floor or swiss ball. This experiment was conducted to compare heart rate, systolic blood pressure, diastolic blood pressure and peripheral vascular oxygen saturation effects by lumbar stabilization exercise in floor or swiss ball with 18 normal adult and it divided 9 subjects. experiment group (1) is applying LSE on floor group and (2) is applying LSE on swiss ball group. Heart rate was measured by portable heart rate manometer, blood pressure was measured by hemodynamometer, and peripheral vascular oxygen concentration was measured using a computerized NURYTEC measuring apparatus analysis. These result lead us to the conclusion that systolic blood pressure and peripheral vascular oxygen concentration were influenced by LSE. but there was not differential effect between each groups. These results suggest that LSE has the capability to improve heart rate, blood pressure, peripheral vascular oxygen concentration. Consequently, LSE would be lead to increment of cardiovascular function.
