Objectives : This comparative study aimed to identify the effect of the Buddeumi(cupping-and-moxibustion device) therapy and moxibustion-only therapy on treating constipation of stroke patients who were admitted in the hospital of oriental medicine. The research design was a nonequivalent control group pretest-posttest design. Methods : The subjects of the study consisted of 23 stroke patients, and they were divided into two groups : one was the experimental group of 11 patients and the other was the control group of 12 patients. The Buddeumi therapy and the moxibustion-only therapy were given respectively. Each Buddeumi and moxibustion-only therapies on the 天樞(ST25, right & left) in abdomen were administered to the each group for 40 minutes a total at 10 times. The posttest included the frequency of defecation with the Constipation Assessment Scale every day for one week after the experiment. The data were analyzed by the $x^2$ test, t-test, Fisher exact test, and repeated measures ANCOVA using SPSS/WIN 12.0 program. Results : The results were as follows : First, Hypothesis 1 : 'The patients who are given the Buddeumi therapy in the experimental group have a lower Constipation Assessment Scale than the control group.' was supported(F=4.367, P=0.049). Second, Hypothesis 2 : 'The patients who are given meridian acupressure in the experimental group have a higher frequency of defecation per week than the control group.' was supported(F=0.947, P=0.034). Accordingly, 'The patients who are given the Buddeumi therapy in experimental group have a higher effect on constipation than the control group.' was supported. Conclusion : The Buddeumi therapy reduced the constipation assessment scale of stroke patients and increased the frequency of their defacation per week. Therefore, the Buddeumi therapy could be an effective treatment for constipation of stroke patients.

A number of atomization and droplet breakup models have been developed and used to predict the diesel spray characteristics. Of the many atomization and droplet breakup models based on the breakup mechanism due to aerodynamic liquid and gas interaction, four models classified as mathematical models, such as TAB, modified TAB, DDB, WB and one of the hybrid model based on WB and TAB models were selected for the assessment of prediction ability of diesel spray dynamics. The assessment of these models by using KIVA-II code was performed by comparing with the experimental data of spray tip penetration and sauter mean diameter(SMD) from the literature. It is found that the prediction of spray tip penetration and SMD by the hybrid model was only influenced by the initial parcel number. All the atomization and droplet breakup models considered here was strongly dependent on the grid resolution. Therefore it is important to check the grid resolution to get an acceptable results in selecting the models. At low injection pressure, modified TAB model could only give the good agreement with experimental data of spray tip penetration and both of modified TAB and DDB models were recommendable for the prediction of SMD. At high injection pressure, hybrid model could only give the good agreement with the experimental data of spray tip penetration and the prediction of all of the selected models did not match the experimental data. Spray tip penetration was increased with the increase the $B_1$ and the increase of $B_1$ did not affected the prediction of SMD.

The purpose of this study was to assess the feasibility of task-oriented arm training for chronic hemiparetic stroke patients. The experimental design in this study was the pre-test and post-test with control group for 4-week intervention. Thirty patients with chronic hemiparetic stroke were recruited from 2 rehabilitation units. The subjects were divided randomly into experimental and control groups. The experimental group conducted task-oriented approach, involving 3 subparts of upper extremity activities, and the control group involved in the general upper extremity exercises. Functional movements of the upper extremities were assessed using clinical measures, including the Fugl-Meyer Assessment-Upper Extremity Section, Box and Block Test, and Action Research Arm Test. The score of Fugl-Meyer Assessment showed greater increases in the experimental group than in the control group after training. The improvement in Box and Block Test between pre-test and post-test measurements was significantly greater after task-oriented arm training compared to general upper extremity exercises. Action Research Arm Test scores also improved after task-oriented arm training compared to exercises in the control group. The task-oriented arm training improves the gross and fine motor activities and encouraging the use of the paretic arm through activity dependent intervention expedites the recovery of functional activities in the upper extremities for chronic hemiparetic stroke.

Background: Motor imagery is the mental representation of an action without overt movement or muscle activation. However, few previous studies have demonstrated motor imagery training effects as an objective assessment tool in patients with early stroke. Objective: To investigate the effect of motor imagery training on Somatosensory Evoked Potentials (SSEP) and upper limb function of stroke patients. Design: A quasi-experimental study. Methods: Twenty-four patients with stroke were enrolled in this study. All subjects were assigned to the experimental or control group. All participants received traditional occupational therapy for 30 minutes, 5 times a week. The experimental group performed an additional task of motor imagery training (MIT) 20 minutes per day, 5 days a week, for 4 weeks. Both groups were assessed using the SSEP amplitude, Fugl-Meyer assessment of upper extremity (FMA UE) and Wolf motor function test. Results: After the intervention, the experimental group showed significant improvement in SSEP amplitude and FMA UE than did the control group. Conclusion: These findings suggest that the MIT effectively improve the SSEP and upper limb function of stroke patients.

Purpose : The aim of this study was to compare the effect of task-oriented training using the PNF(proprioceptive neuromuscular facilitation) and task-oriented training with chronic stroke patients. Methods : Sixteen chronic stroke patients participated. Participants were randomly assigned to the control and experimental group( 8 experimental, 8 control). All of participants were in-patients at local hospital and had been received training appropriate to the purpose of each group program. Experimental period was carried out 30 minutes/day, five days/week, during four weeks. The experimental group trained the task-oriented training using the PNF and control group trained the task-oriented training. Fugl-meyer assessment scale and Modified Barthel Index was measured to compare the upper arm function and activities of daily living. We were measured before and after the training. Results : The results of the study were as follow: Fugl-meyer assessment scale was significantly increased both groups(p<.05), and significant between groups(p<.05). Modified Barthel index was significantly increased both groups(p<.05) and between groups(p<.05). Conclusion : PNF can be effective in improving upper arm function and ability to perform daily life of chronic stroke patients.
