Purpose : This study was performed as follows in order to investigate the effect of presynaptic inhibition mechanism using the transcutaneous electrical stimulation (TES) for global synkinesis (GS) on the post-stroke hemiplegic patients. Methods : The subjects consist of 38 post stroke hemiplegic patients; experiments were performed on thirty patients excluding eight. The experiment was performed on sham group, sensory level stimulation group, and motor level stimulation group for 20 minutes a day 5 times a week for 6 weeks total. We compared the differences in GS levels and walking ability. The measurements were carried out pre, immediated, post 10th, and 20th, for a total of four measurements. Results : The GS level using sEMG found significant differences between groups at the post 10th and post 20th in dorsiflexion, and post 20th in plantarflexion (p<0.05, p<0.01). The motor level group indicated more significant differences when the number of electrical stimulations increased. TUG and 10 m walking test indicated a significant difference at immediated, post 10th, and post 20th. The motor level group showed more significant decreasing tendency than the sensory level group. Conclusion: From these results, electrical stimulation using presynaptic inhibition mechanism of transcutaneous electrical stimulation (TES) had positive effects for walking ability on inhibition of muscle tone in lower extremity. The motor level stimulation group experienced a more significant effect than the sensory level stimulation group. Therefore, the transcutaneous electrical stimulation (TES) is considered to be effective on walking ability increasing through inhibition of muscle tone in lower extremity for rehabilitation of post stroke hemiplegic patients.

Purpose : This study was to evaluate the effect of traditional balance training on balance in older adults. Methods : The subjects of this study were thirty elderly over 65 years old. Thirty subjects ranging aged from 66 to 85($74.0{\pm}5.83$) completed the study and participated three times a week for 5weeks. Subjects were assessed by utilizing two different balance measure : Static standing balance was measured by balance performance monitor(BPM). Dynamic balance was measured by timed up and go test(TUG). The scale for static standing balance was measured by using frequence(Hz), sway area($mm^2$), sway path(mm), max sway velocity(mm/s), ant/post sway angle($^{\circ}$), left/right sway angle($^{\circ}$), and sway number. Results : The change in frequency were statistically significant on pre-test and post-test(P<.05), 2. The change in sway area were statistically significant on pre-test and post-test (P<.05), 3. The change in sway path were statistically significant on pre-test and post-test(P<.05), 4. The change in max sway velocity were statistically significant on pre-test and post-test (P<.05), 5. The change in ant/post sway angle were statistically significant on pre-test and post-test (P<.05), 6. The change in left/right sway angle were statistically significant on pre-test and post-test(P<.05), 7. The change in sway number were statistically significant on pre-test and post-test(P<.05), 8. The score on timed up and go test shows statistically significant increase on pre-test and post-test (P<.05). Conclusion : This study suggest that traditional balance training have an effect on balance performance ability for elderly people. Therefore, the traditional balance training is recommended for older adults to improve balance performance ability.

The purpose of this study was to evaluate the effect of post space preparation on apical sealing according to the methods and time of gutta percha removal. Forty six extracted single rooted teeth were selected for this study. Forty teeth were used as experimental groups and six teeth as control groups. Forty teeth were routinely prepared by step-back method and obturated with gutta percha cones and zinc oxide-eugenol cement using lateral condensation. All obturated teeth were divided into 4 groups of 10 teeth each. In each group of 1, 2, 3, heated plugger, gate glidden drill and chloroform and K-file were used respectively for post space preparation by removing the gutta percha immediately after obturation. In group 4, post space were prepared with gate glidden drill one week after obturation. In all experimental groups, the post space were prepared so that 4mm of apical gutta percha remained. After post space preparation, apical leakage were measured with electrochemical method for 28 days and analyzed statistically. The following results were obtained ; 1. No statistically significant differences in apical leakage were occured among the experimental groups using heated plugger, gate glidden drill and chloroform and K-file to remove the gutta percha immediately after obturation. 2. No significant difference in apical leakage was found between the teeth prepared post space immediately after obturation and those prepared 1 week after obturation. 3. In all experimental groups, the apical leakage was increased with time passage regardless of the post space preparation time and the gutta percha removal techniques.

Although the study of post-adoption has increased in recent years, few studies have focused on the moderating effect of uncertainty avoidance on the relationship between post-expectation and behavior. The purpose of this study is to examine the moderating effect of uncertainty avoidance in the mobile Internet domains. This study proposed a post-adoption model based on prior continuance model. This theoretical model was verified empirically by conducting web surveys and multi-group analysis. Based on the survey data, we classified users into those with high uncertainty avoidance and those with low uncertainty avoidance. The results indicate that post expectations have significant impacts on satisfaction and continuance intention. The results also show that the impacts of intrinsic motivational factors of mobile Internet services on satisfaction and continuance intention are stronger for users with high uncertainty avoidance. On the other hand, the impacts of extrinsic motivational factors on satisfaction and continuance intention are stronger for users with low uncertainty avoidance, with a few exceptions. This paper ends with theoretical and managerial implications of the study results, as well as limitations and future research directions.

This study aims to develop new constructs and indicators for sharia destination image, and then examine its effects on perceived value, tourist satisfaction, and post-visit behaviour. Furthermore, it analyses the mediating role of perceived value and tourist satisfaction on relationship between sharia destination image and post-visit behaviour. The population were domestic and Malaysian Muslim tourists who visited Aceh during the study period. The sampling was carried out in two stages. The first stage involved selecting most visited districts. The second stage involved randomly selecting tourists who visit during the study period in the districts. Data was collected using a structured questionnaire with a Likert scale. Also, a total of 270 questionnaires were distributed to domestic and Malaysian tourists in Aceh. Cluster sampling was used to determine the sample area, and purposive sampling technique was used to determine the study sample. Furthermore, the data analysis technique is Structural Equation Modelling. The results showed that the sharia destination image has a significant effect on perceived value. Meanwhile, the perceived value significantly influenced tourist satisfaction and post-visit behaviour. In addition, the perceived value and tourist satisfaction can mediate the effects of sharia destination image, which has no direct effect on post-visit behaviour.

The ripple effect is analyzed in the post-construction evaluation phase, but only the qualitative analysis and simple numerical fluctuations are analyzed, thus, no reliable ripple-effect analysis has been conducted. Therefore, in this study, a focus group interview was conducted with 10 experts to propose a plan to improve the ripple effect metrics. Consequently, by linking with the policy-effect metrics of the pre-feasibility study, it is expected that the utilization of the analysis results will be improved and objective and quantitative analysis will be possible.

Objective : Post-traumatic hydrocephalus is a complication of head injury and can present with several different clinical symptoms. However, the developing factors of post-traumatic hydrocephalus and treatment are still not well known. The authors design the study to focus on incidence, causing diseases and treatment of post-traumatic hydrocephalus. Methods : The 789patients of traumatic head injury followed by admission treatment over 7days from Jan. 1997 to Dec. 2001, were divided shunt group and shunt free group. We analyzed age, sex, causing diseases, developing time of hydrocephalus and effects of shunt operation in post-traumatic hydrocephalus. Results : The incidence of post-traumatic hydrocephalus for requiring shunt was 9.2% [64cases]. Chronic hydrocephalus which developed after 14days of injury was higher incidence [51cases]. We found following variables were significantly related to shunt-dependent hydrocephalus : low GCS score at admission, initial CT finding of traumatic subarachnoid hemorrhage and intracerebral hemorrhage [including intraventricular hemorrhage]. The effect of shunt operation was not related with the spinal pressure, but had statistically significant correlation with the response of lumbar drainage. Conclusion : We conclude that development of hydrocephalus after head trauma is related to low GCS score, intracerebral hemorrhage [including intraventricular hemorrhage] and subarachnoid hemorrhage. The effect of preoperative lumbar drainage has a significant role in predicting the result of shunt operation in patient with post-traumatic hydrocephalus.
