Purpose : The purpose of this study was to identify the effect of recovery of disability on post-stroke depression in stroke patients. Methods : Fifty patients with stroke were participated in this study. The stroke impact scale(SIS) was used to assess the recovery of disability according to stroke and short form of geriatric depression scale(SGDS) was used to assess the poststroke depression(PSD). Results : The suspicious for depression were exhibited in 38%(n=19) and patients with depression were 58% (n=26) of 50 patients with stroke. In correlation between recovery of disability and depression, emotion and recovery of stroke negatively correlated with depression(p<.05). Conclusion : These results demonstrates that patients with stroke need to manage and treat emotion for the prevention and management of PSD.

현재까지 국내에서 진행되어 온 서비스 실패와 회복 관련 연구들은 한국인의 정서적인 측면을 많이 고려하지 않았다. 한국인의 특성 상 이러한 감정적인 측면이 서비스 회복과정에서 작용할 수 있음에도 불구하고 대부분의 선행연구들은 기존에 해외문헌에서 주로 다루어진 변수들만으로 연구를 진행하였다. 그러나 실제 국내의 서비스 상황에서 발생하는 서비스 회복 과정에서는 소비자가 지각하는 정이라는 개념이 작용하는 경우가 많다. 이에, 관련 연구의 이해의 폭을 넓히고, 정이라는 개념을 실무에 적용하기 위해서는 추가적인 연구결과가 필요하다고 판단하였다. 따라서 본 연구에서는 기존연구의 한계점을 고려하여 서비스 회복상황에서 지각된 공정성과 고객이 지각하는 서비스제공자에 대한 정의 역할을 함께 살펴보았다. 이를 통해 국내 고객관점에서의 서비스 실패 상황에 적합한 서비스 회복모형에 대해서 고찰할 수 있는 계기를 마련하였다. 본 연구의 결과를 통해 단순히 서비스 회복 노력의 공정성뿐만 아니라 서비스 실패 후 회복과정에서 고객이 지각하는 정이라는 한국인 고유의 감정의 조절효과를 살펴봄으로써 고객의 이해심을 구할 수 있는 진심어린 회복노력의 중요성을 확인할 수 있다.

This study was investigated the effects of pain and functional recovery when low frequency electrical stimulation and aquatic exercise applied to sciatic nerve injured rats. The rats were assigned into four groups; Group I(n=20, control group), Group II(n=20, low frequency electrical stimulation group), Group III(n=20, aquatic exercise group), Group (n=20, applied low frequency electrical stimulation and aquaatic exercise group). Each IV group measured hot plate examination, sciatic nerve functional index(SFI), c-fos.. In hot plate examination, group II, IV showed effect than group Iat 14 days after injured(p<0.01) and group III, Ⅳ showed effect than group I at 21, 28 days after in-jured(p<0.01, p<0.001). In SFI, group II, III, IV showed effect II, III, IV than group I and group IV showed effect than group II at 14, 21 days after injured(p<0.001). group II, III, IV showed effect than group I at 28 days after injured(II = p<0.01, III and IV = p<0.001). Effects of pain and function recovery when low frequency electrical stimulation and aqua-exercise applied to sciatic nerve injured rats, group Ⅳ were most effected to sciatic nerve injured rats. As well as group II and III were effected to sciatic nerve injured rats.

The purpose of this research is to study the utility of prediction program like a F.E.M. analysis for energy recovery of heat exchanger with heat pipe which uses arbitrary groove wick. The program is based on the utility by the experimental and applytical method of the single heat pipe. It is also expanded and applied in the prediction program of the heat exchanger. The results are as follows; 1) The effective thermal conductivity of the groove wick with arbitrary shape is counted by the thermal resistance change. 2) The more the number of rows, the more the effect energy recovery changing by the number of rows, the bigger the free velocity, the smaller the effect of energy recovery. 3) The effect of energy recovery increases according to the value of the rate of mass flow (Me/Mc) and also number of rows. 4) The comparison between calculated and data shows good agreement within 2.5% error, therefore the F.E.M. analysis of the study is useful to predict the performance of heat pipe-heat exchanger.

This study was to examine on the respiratory variables, heart rate and muscle activity between the static recovery and dynamic recovery after progressive resistance exercise to maximal point. Subjects were 15 students enrolled in N University. All were tested two times (static recovery and dynamic recovery) and were requested to perform a walking on a treadmill after progressive resistance exercise to maximal point. Electromyography(EMG) was used to monitor the muscle activity(TA: Tibialis Anterior, MG: Medial Gastrocnemius) during gait. CPEX-1 was used to measure the respiratory variables and heart rate. The dynamic recovery group was shown the significant lower heart rate than that of static recovery group at during gait. Respiratory rate showed statistically a significant difference. Electromyography(RMS, root mean square) showed a non-significant difference. But the dynamic recovery group of muscle activity was found highly in TA and MG. This study indicated that the dynamic recovery method evidenced more faster than the static recovery method. And this type of dynamic rest by walking can be a help of recovery after exercise.

The objective of this study was to evaluate the effects of mirror therapy on motor function recovery following a stroke through a systemic review and meta-analysis. In total, nine of the 48 studies were identified from search engines between 1997 and 2011, as well as from a review of the reference lists of each identified study. The quality of each study was assessed using Jadad scale, and the effect size was calculated as a Cohen's effect size using MetaAnalyst (Beta 3.13). The overall effect size of the mirror therapy was 2.005 (95% confidence interval=1.041~2.970) in a random-effects model. This finding suggests that mirror therapy is beneficial for improving motor function following a stroke. The results from the subgroup analysis according to categorical variables were as follows: First, the effect size was larger for an onset time of less than 1 year (1.166) than for a duration of 1 year or more (.668). Second, the effect size of unpublished dissertations (1.610) was larger than published articles (1.221). Third, motor recovery of upper extremities (1.609) had a greater effect than motor recovery of lower extremities (.903). The major limitation of this study is the relatively small study population. Therefore, further individual studies of mirror therapy should be conducted in order to generalize the effects. In addition, mirror therapy supervised by a physical therapist should be recognized as a potential approach to manage motor function following a stroke and recommended to patients to improve their motor function.

In a low-voltage distribution system, the molded case circuit breaker (MCCB) is a widely used device to protect loads by interrupting over-current; however the hot gas generated from the arc discharge in the interrupting process depletes the dielectric recovery strength between electrodes and leads to re-ignition after current-zero. Even though the circuit breaker is ordinarily tripped and successfully interrupts the over-current, the re-ignition causes the over-current to flow to the load again, which carries over the failure interruption. Therefore, it is necessary to understand the dielectric recovery process and the dielectric recovery voltage of the MCCB. To determine these characteristics, a measuring system comprised of the experimental circuit and source is implemented to apply controllable recovery voltage and over-current. By changing the controllable recovery voltage, in this work, re-ignition is driven repeatedly to obtain the dielectric recovery voltage V-t curve, which is used to analyze the dielectric recovery strength of the MCCB. A measuring system and an evaluation technique for the dielectric recovery strength of the MCCB are described. By using this system and method, the measurement to find out the dielectric recovery characteristics after current-zero for ready-made products is done and it is confirmed that which internal structure of the MCCB affects the dielectric recovery characteristics.

Actuators using shape memory alloys use the one-way shape recovery stress. But when external load is applied the accumulated plastic strain induced by repeated deformation is the factor of generation of uncorrect recovery stress and unreliability. To solve this problem, two-way shape memory effect (TWSME) is considered. TWSME induced by plastic deformation have advantages including simple heating cycle without external force and enough recovery force for using actuators. but there is no research on cylinder-type or tube-type shape memory alloy actuators using two-way shape memory effect until now. Therefore in this study, characteristics of two-way shape memory effect is verified through the compression experiments using cylinder-type and tube-type specimens.

Objectives : This study is aimed to evaluate and objectify the therapeutic effect of moxibustion on muscle fatigue recovery. Methods : To evaluate the therapeutic effect on the muscle fatigue recovery, we compared the fatigue recovery of two groups (non-stimulation group and moxibustion group) by analyzing the EMG and peak torque after strenuous knee exercise of isokinetic contraction. Results : The median frequency (MF) of the moxibustion group was recovered faster than that of the non-stimulation group. However, the peak torques of both groups were not restored until after 20 minutes. Nevertheless, the moxibustion group's peak torque was regained higher than that of the non-stimulation group. Conclusions : We confirmed the therapeutic effect of moxibustion and found that the moxibustion can used as prevention method for musculoskeletal disease.
