Purpose : This study was conducted to examine the effects of unstable surface training and galvanic vestibular stimulation on balance and proprioception. Methods : 4-week training was applied to 40 normal adults in their twenties (unstable surface training group 10, galvanic vestibular stimulation group 10, unstable surface training and galvanic vestibular stimulation group 10, control group 10). Balance and proprioception was measured before the experiment, after two weeks, and after four weeks. Repeated ANOVA was used for balance and proprioception analysis. Results : As a result of repeated ANOVA on balance changes in double support, a significant difference was found in open sight in interaction among groups and periods (p<0.05). As a result of repeated ANOVA on balance changes in double support, there was a significant difference in closed sight and interaction among groups and periods (p<0.05). As a result of repeated ANOVA on balance changes in proprioception, there was no statistically significant difference in interaction among groups and periods. Conclusion : In conclusion, both unstable surface training and galvanic vestibular stimulation had positive effect on balance control and proprioception improvement, and their excellence was not greatly different. Thus, it is possible to use unstable surface training and galvanic vestibular stimulation for physical therapy intervention to improve balance and proprioception. Since the results showed that simultaneous application of two methods had greater effects on difference compared with a single application, it is suggested to use this intervention in the clinical field.

Purpose: This study aimed to investigate the effect of robot-assisted gait training on the active ranges of motion, gait abilities, and biomechanical characteristics of gait in patients who underwent lower extremity surgery, and to verify the effectiveness and clinical usefulness of robot-assisted gait training. Methods: This study was conducted on 14 subjects who underwent lower extremity surgery. The subjects participated in robot-assisted gait training for 2 weeks. The active ranges of motion of the lower extremities were evaluated, and gait abilities were assessed using 10-m and 2-min walk tests. An STT Systems Inertial Measurement Unit was used to collect data on biomechanical characteristics during gait. Spatiotemporal parameters were used to measure cadence, step length, and velocity, and kinematic parameters were used to measure hip and knee joint movement during gait. Results: Significant improvements in the active ranges of motion of the hip and knee joints (flexion, extension, abduction, and adduction) and in the 10-m and 2-min walk test results were observed after robot-assisted gait training (p < 0.05). In addition, biomechanical characteristics of gait, spatiotemporal factors (cadence, step length, and velocity), and kinematic factors (gait hip flexion-extension, internal rotation-external rotation angle, and knee joint flexion-extension) were also significantly improved (p < 0.05). Conclusion: The results of this study are of clinical importance as they demonstrate that robot-assisted gait training can be used as an effective intervention method for patients who have undergone lower extremity surgery. Furthermore, the findings of this study are clinically meaningful as they expand the scope of robot-assisted gait training, which is currently mainly applied to patients with central nervous system conditions.

Purpose: The purpose of this study was to identify factors related to nurses' organizational citizenship behavior using multilevel analysis which included both nurse characteristics at individual levels and nursing unit characteristics at group levels. Methods: The sample was composed of 1,996 nurses who were selected from 182 nursing units in 28 hospitals in six metropolitan cities and seven provinces using cluster sampling. Data were collected using self-reported questionnaires from February to March 2006. Results: The results of the study indicated that individual level variables related to organizational citizenship behavior were religion, job position, clinical career, self efficacy, positive affectivity, and supervisor support. The group level variables related to organizational citizenship behavior were collective efficacy, number of nurses in a nursing unit, and the average salary level of a nursing unit. 30.9% of individual level variances of organizational citizenship behavior were explained by the nurses' individual level variables. The explanatory power of group level variables, which is related to group level variances of organizational citizenship behavior, was 75.5%. Conclusion: This research showed that it was necessary to develop appropriate strategies related to not only individual factors, but also higher-level organizational factors such as collective efficacy, to improve individual performances in the hospital.

Purpose : The purpose of this study was to investigate the correlations between clinical balance scales and Balance Performance Monitor parameters in patient with adolescent idiopathic scoliosis (AIS). Methods : Twenty AIS subjects (age, $14.26{\pm}1.93yrs$; height, $160.56{\pm}7.98cm$; weight, $47.54{\pm}6.94kg$)were participated in this study. Postural sway(mean balance, sway angle, sway area, sway path, maximal sway velocity) were were evaluated by balance performance monitor. Measurements for clinical balance scales were Functional reach test (both side), the Lateral reach test (both side) and One leg standing test (both legs). Results : The results were as follows. There were positive strong correlation between major curve direction and left-right sway angle, sway path, maximal sway velocity. There were negative strong correlation between the functional reach and left-right sway angle, sway area, sway path, maximal sway velocity. And the lateral reach were also showed negative strong correlation parameters of balance performance monitor. One leg standing were negatively correlated with left-right sway angle, sway path, maximal sway velocity. Conclusion : The clinical balance scales will be useful tools for balance measurements, and basic tools for clinical setting for patient with AIS.

각 장기는 고유한 명암값의 범위와 각 명암값에 대한 서로 다른 비율을 지니고 있으므로 제안된 연구에서는 이러한 명암값의 비율을 이용하여 장기의 영역과 노이즈를 구분할 수 있도록 하였다. 장기의 영역을 세 종류의 메쉬영상으로 표현하여 이들의 유니온 영상으로 장기의 전반적인 형태인 템플리트를 생성하였다. 템플리트 방식은 기존의 방식에서 명암값의 범위가 같은 노이즈의 제거가 어려운 단점을 해결하여 장기의 영역만을 분리할 수 있었다. 장기의 위치를 탐색하기 위한 위치탐색과정에서는 장기의 존재여부의 파악과 함께 분리된 장기까지 추적할 수 있도록 하였다. 외곽선 표현을 위해서는 템플리트로 이진영상에서 서브트랙션(subtraction)하는 방법을 사용하여 장기의 말단부위까지 세밀하게 표현하였다. 제안된 연구에서 사용된 오프닝과 클로징 방법으로 기존의 structuring element를 사용하는 방법에 비해 처리속도를 단축시킬 수 있었다. 추출된 장기의 면적을 토대로 체적계산을 시행하였고 동물실험을 통하여 임상 실험치를 제시하였다.
