Purpose: The aim of this study was to determine the effectiveness of pelvic tilt training using an inclinometer on joint position sense and postural alignment in individuals with stroke. Methods: Thirty-one subjects with chronic stroke were divided into two groups: the experimental group (16 subjects) and the control group (15 subjects). Subjects in both groups received neuro-developmental therapy five times per week. In addition, the patients in the experimental group also received pelvic tilt training using an inclinometer for 30 minutes, 3 times a week for 4 weeks. Maximal range of anterior, posterior pelvic tilt and joint position sense were used to evaluate pelvic tilt motion. Image analysis was performed for evaluation of postural alignment on in standing position. Results: Significant difference in Iimprovement of pre- and post-intervention of joint position sense was observed showed significant difference (p<0.05) in all groups. Experimental groups showed sSignificant differences in maximal range of posterior pelvic tilt in on the paretic side were observed in the experimental groups compared to with the control group (p<0.05). Conclusion: These findings suggest that pelvic tilt training using an inclinometer may help to improve range of pelvic tilt and joint position sense of stroke patients.

This study had performed with purposes to analyze the influence of the change of vestibular sens, visual and proprioceptive sense to the postural sway, so as to supply the necessary clinical materials through developing the physical therapeutic interventions and assessment format for the diabetic neuropathy patients. The sample consisted of fifteen diabetic neuropathy patients with sensory disorder in their lower limbs and fifteen age-matched normal control group. Then the effect of the GVS and the visual cue open and closed to the postural sway were measured by CoP. The summary of the comparison results were obtained below. In the comparison of diabetes neuropathy patients group and age matched normal control group, however diabetes neuropathy patients group had a decrease in superficial tactile sense(p<.001) and nerve conduction velocity(p<.001), they were able to control the posture and walk. So it is, diabetes neuropaty patients had more disturbance compared with AMC group on at a hard surface, particularly in the visual cue open(p<.001) and visual cue closed(p<.01). Moreover, since diabetes neuropathy patients group had more differences in visual cue open and closed(p<. 01), GVS(p<.01), it meant that they're affected largely by vestibular sense, visual sense. In addition, since there're the largest change in doubled sense disturbance such as visual cue open and closed under GVS, it meant that compensation of other senses were quite important for the diabetes neuropathy patients' postural control. In the conclusion, diabetes neuropathy patients who decrease or lose the somatosensory system, sensory training of visual and vestibular system are likely to be quite essential to control the posture and balance.

In this paper, the virtual reality system is tried to developed, which controls not only the sense of sight and hearing but also the sense of touch, In order to develope the sense of touch in this study, the stable tactual transaction system, based on summing up the basic algorithm and theory is embodied. Especially, the graphic deformation algorithm is developed in realtime with using the deformed FEM. To apply the FEM, a deformed material model is produced and then the graphic deformation with this model is able to force. Finally, the graphic transaction algorithm is deduced by the realtime calculation and simplification because the purpose of this system is to transact in real time. The result of this study is that the proposed system is possible to deform the graphics and transact the haptic in real time in PC. The simulation program has been made to prove this result.

Objectives : This study develops a salutogenic program and examines its effects on the sense of coherence, acculturative stress, and quality of life of married immigrant women. Methods : The salutogenic program was developed based on Antonovsky's Salutogenic Model, and the study design was a nonequivalent control group pre-post test design. The participants were married immigrant Chinese (n=30) and Vietnamese (n=31) women, who were assigned to either an experimental group (n=29) or a control group (n=32). The data were analyzed using the ${\chi}^2$-test, t-test, Fisher's exact test, and repeated measures ANOVA, and the IBM SPSS for Windows (version 20.0) program was used to perform the analysis. Results : Compared to the control group, the sense of coherence (F=52.05, p <.001) and quality of life (F=6.95, p=.002) were significantly improved in the experimental group, and the acculturative stress (F=24.64, p<.001) in this group significantly decreased after implementing salutogenic program. Conclusions : These findings indicate that a salutogenic program is an effective intervention for married immigrant women. The study suggests that such programs can be applied to married immigrant women at public health or multicultural family support centers to improve their sense of coherence and quality of life.

In this paper, we present the development of a new training system for equilibrium sense and postural control. This system consists of an unstable platform, a force plate, a computer, and training programs. The unstable platform provides 360 degrees of movement allowing for training in all directions. To evaluate the effects of the training system, we performed various experiments to train the ability of equilibrium sense and postural control of fifteen young healthy subjects. We measured the time a subject maintains his or her center of pressure on a target, the time a subject moves his or her center of pressure to a target, and the mean absolute deviation of the trace before and after the training. We analyzed these parameters obtained before and after the training using paried-sample T-test. The result shows that the subjects experienced distinctive enhancement in their ability of postural control through the training using our system.

This paper investigates the economic design of synthetic control charts. The synthetic control chart has been proven to be statistically superior to the $\bar{X}$-control chart, but its economic characteristics have not been known. We develop an economic model of the synthetic control chart, based on Duncan's model. The synthetic chart has one more decision variable, the lower control limit for the conforming run length. In addition to this, the significance level and the power of the synthetic chart are more complicated than those of the $\bar{X}$-chart. These features make the optimization problem more difficult. We propose an optimization algorithm by adapting the congruent gradient algorithm. We compare the optimal cost of the synthetic chart with that of (equation omitted)-control chart, under the same input parameter set of Duncan’s. For all cases investigated, the synthetic chart shows superior to the $\bar{X}$-chart. The synthetic control chart is easy to implement, and it has better characteristics than the $\bar{X}$-chart in economical sense as well as in statistical sense, so it will be a good alternative to the traditional control charts.
