Objective: To test the null hypothesis that SmartClip self-ligating brackets are more effective than conventional brackets for initial mandibular alignment and identify influential factors. Methods: Fifty patients were randomly allocated to two equal treatment groups by using an online randomization program: self-ligating group (SmartClip brackets) and conventional group (Gemini brackets). The archwire sequence was standardized. Changes in anterior irregularity index, intercanine width, and intermolar width were assessed on plaster models at 8th and 16th weeks. Changes in incisor position and inclination were assessed on lateral cephalometric radiographs at 16 weeks. Intragroup and intergroup comparisons were performed with paired t-test and Student's t-test, respectively. Multiple linear regression was performed to identify variables affecting improvement in anterior ambiguity. Results: Data of 46 patients were analyzed; those missing an appointment (n = 2) or showing bracket breakage (n = 2) were excluded. Incisor inclination (p < 0.05), intercanine width (p < 0.05), and intermolar width (p > 0.05) increased at 8 and 16 weeks in both the groups; no significant intergroup differences were noted (p > 0.05). Initial anterior irregularity index and intercanine width change were significantly associated with improvement in anterior irregularity (p < 0.001). Conclusions: The null hypothesis was rejected. Bracket type has little effect on improvement in anterior ambiguity during initial mandibular alignment.
PURPOSE: The aim of this study is to verify the effectiveness of modified constraint-induced movement therapy(mCIMT) on upper function and activities of daily living in people with subacute stroke patients. METHODS: Eighteen participants, with subacute stroke that were randomly assigned to either the experimental group(n=9) or the control group(n=9). For subjects from the experimental group modified Constraint-Induced Movement Therapy was performed. exercise program, the patient trained in affected side upper extremity with restricted non-affected side for 1 hour and using in activity daily living for 4 hours for five times per week, during 4 weeks. For subjects from the control group, conventional upper extremity training was performed. Outcomes such as the box and block test(BBT), Fugl-Meyer motor function assessment(FMA), and modified Barthel index(MBI) were measured before and after training. Between-group and within-group comparisons were analyzed by using Independent t-test and Paired t-test respectively. RESULTS: These finding suggest that experimental group was significant increase in BBT, FMA, MBI(p<.05). In comparison of two group, experimental group was high upper function and activity daily living than control group. CONCLUSION: This study showed experimental group can be used to improve upper function and activity daily living than control group. Thus it indicates that mCIMT will be more improved through the continued upper extremity exercise program.
Objective. The 12 forms of Sun-style Tai Chi exercise has been developed specifically for arthritis patients in order to reduce their symptoms and to improve physical functioning. This quasi-experimental study examined the changes in pain, balance, muscle strength and physical functioning in women with osteoarthritis at the completion of the 12 week Tai Chi exercise program. Methods. The patients with osteoarthritis who signed the consent form were screened by their primary physician according to the inclusion criteria and invited to the study. Total of 66 osteoarthritis women with an average age of 63 years were participated in the Tai Chi exercise. At the completion of 12 weeks, 34 patients completed both pretest and posttest measures with 48% of overall dropout rate. Outcome measures were physical symptoms, balance, muscle strength, physical functioning, and depression. Paired t-test was utilized to examine differences between pre and post-measures. Results. After participating in the Tai Chi exercise program, the women with osteoarthritis showed significant improvements in their physical fitness measures, and consequently in their physical functioning. In physical fitness test, there were significant improvements in balance, flexibility, muscle strengths of knee, grip, and back muscles after the Tai Chi exercise. However, No significant differences were found in pain and stiffness of their knee joints and depression measure. Conclusion. The 12 forms of Tai Chi exercise has been found safely applicable to the older women with osteoarthritis for 12 weeks, and effective in improving balance, flexibility, and muscle strengths, and consequently lessening difficulties of performing their activities of daily life.
PURPOSE: This study investigated the effects of unilateral static stretching on the flexibility and symmetry of the lower leg, and temporal gait variables in gait asymmetry people. METHODS: Twenty gait asymmetry people were divided into a unilateral static stretching group (USG, n = 10) and control group (CON, n = 10). The USG performed unilateral static stretching for 60 minutes, three times a week, and eight weeks. The flexibility of the lower leg (SR), and symmetry (BR), and temporal gait variables (Step length; SL, gait speed; GS) were measured before, after four and eight weeks of unilateral static stretching. Moreover, SI (symmetry index; SI) was calculated from the measured SL value. Statistical analyses were conducted using one-way ANOVA and two-way ANOVA with repeated measures, a paired t-test, and multiple comparisons according to Scheffe. RESULTS: SR and BR in the dominant and non-dominant side, and GS were increased significantly at USG after eight-weeks compared to before unilateral static stretching (p < .05). The difference in BR in the dominant and non-dominant side, and step length (SI) decreased significantly at USG after eight-weeks compared to before unilateral static stretching (p < .05). CONCLUSION: Unilateral static stretching improves the flexibility and symmetry of the lower leg, and temporal gait variables in gait asymmetry people.
In order to flatter the figures of average middle aged women by determining harmonious proportions for their costume forms, this study evaluates effects of varying design details of jackets(coats) with blouses and slacks using a ranking test and paired comparisons test. The result from clothing design C-2 which has the best design effect were as follows; 1. In order to look taller, the jacket(coats) is divided vertical long line and it has the emphasis point close to the face. 2. In order to make shoulder width look wider, armhole seam line attached 1-2 cm from the shoulder point. 3. In order to make chest width look slimmer, division was made up of a tailored collar with a deep V-neckline. 4. In order to make waist circumference look slimmer, the jacket has more fitted waist line than loosed it and tailored collar with a deep V-neckline. 5. In the case of the division of upper and lower garments, when the division was closer to the golden section, i.e., when the jacket hemline is hipline and slacks length is the heel excluded length of shoe heels, the overall appearance was better. 6. The V-neckline looked better, when it was cut along a long acute angle to the waist line. Because of dividing along above factors 1-6 i.e., clothing design C-2 was overall harmonious. Appropriate division of costume forms made for an aesthetic composition, which flattered the body types of middle aged women and presented harmonious, beautiful costume design effects. It made the women look taller, slim and balanced, and highlighted middle aged women's sense of beauty.
Evaluation plays an essential role in design activity. Many theorist have agreed that designing involves problem solving or decision making. In evaluation, designers attempt to determine the value of a particular proposal arrived at by synthesis. And the results of designing, the product, is evaluated twice, objectively and subjectively.Alternatives in $$\mu$ti-objective decision problems generally possess numerous attributes by which they can be described and compared. The evaluation factors include all attributes that have levels specified by quantitative and qualitative objectives. However since qualitiative factors are difficult to quantify as $$\mu$eral estmates, these factors have tended to be ignored without regard for their importance to human content. Therefore we need some study that convert qualitative attributes into quantitative scale values. Following to Thurstone' s Psychological scaling methods (The method of successive intervals), attribute values of TV set are assigned by rating scale methods. The method of successive intervals, like the method of equal-appearing intervals, requires but a single judgement from each subject for each statement to be scaled. It is, therefore, a convinient method to use when the number of to be scaled is large. We make the assumtion that those cu$$\mu$ative proportion distributions are normal for each statement when they are projected on the unknown psychological continuum. In this study, we have determined the scale values of 42 statements of TV set by the method of successive intervals. Then we can apply a test of internal consistency similar to that used with the method of paired comparisons. We have as our absolute average deviation, -1.748/252= -0.0069. We have reason to believe that our scale values are consistent with the empirical data, because these discrepanicies are very small.
Purpose: The purpose of this study was to effect of application methods of stretching exercise on angular variation and muscle activation changes in the hallux valgus. Method : This study was performed on twenty subjects. Twenty subjects were divided into two groups; Agonist Contraction(AC)(n=10), Hold-relax with Agonist Contraction(HR-AC)(n=10). Both of the group performed the exercise 5 times a week for 6 weeks. The data was analyzed by the paired t-test for comparing before and after changes of factors in each group and the independent t-test for comparing the between groups. Result : In the within group comparisons, HR-AC group abductor hallucis muscle activity showed significant difference between before and after the intervention(p<0.01). And all the two groups, there were significant decreased in hallux valgus angle(p<0.01). In the comparison of the two groups, there were significant difference among the two groups in abductor hallucis muscle activity(p<0.01). Conclusion : The findings of this study, we found that the HR-AC technique were more effective than AC technique in increase in abductor hallucis muscle activity.
Background: The purpose of this study was to investigate how the resistive exercises with vibration stimuli could affect the strength of knee muscles and balance in patients with a history of reconstructive surgery. Methods: Thirty four subjects with anterior cruciate ligament reconstruction were randomly divided into 3 groups; Resistive exercises with vibration stimuli group (n=11), Resistive exercises (n=11) and control group (n=12). The paired t-test was used to show the variation before and after exercise in all three groups. One way ANOVA was used to separate the total variation between groups. Results: The results showed that there was significant improve in the strength of knee muscles in all three groups and resistive exercise with vibration stimuli he group showed a better result in all area than the other two groups. Comparisons of sway distances with open and closed eyes showed a statistically significant decrease before and after treatment in all three groups, there was no statistically significant difference between groups. There was a significant difference only in the sway distance with the eyes closed. Conclusions: Applying the resistive exercise with vibration stimuli as a therapeutic exercise program resulted in a positive effect to the functional activity not only in rapidly recovering the strength the weaken muscles and lost of balance ability, but also expecting an earlier return to daily life by advancing the date of the process for the functional activity.
Purpose: This research was done to compare obstetric pain, anxiety and cervical dilatation between an epidural analgesia group and a control group. Methods: Participants were assigned to the experimental or control group depending on their decisions for pain relief. Subjective / objective obstetric pain, anxiety level and cervical dilatation were measured and ANOVA was used for comparison of groups and paired t-test to make pre-post comparisons. Results: Homogeneity of pain, anxiety and cervical dilatation were assessed at the latent phase. Cervical dilatation was larger in the control group than the experimental group, at both the active and the transitional phase (F=22.9, p<.001; F=39.9, p<.001 respectively). The degree of pain and anxiety were not significantly different between the groups. Within the experimental group, subjective / objective pain and anxiety level were significantly lower post-analgesia compared to pre-analgesia in the active phase. All variables, except for sweating in the objective pain measurement, changed significantly at the transient phase. Conclusion: The results of this evidence-based research indicate that epidural analgesia while effective in relieving pain and anxiety may have an adverse effect on the cervix during labor stage I. Epidural analgesia should be used carefully during cervical dilatation in labor stage I.

Background: The aims of this study were to analyze the anatomic variations of supraorbital foramina/notches in Koreans and to compare the results with those of previous studies examining other races. We evaluated the three-dimensional computed tomography (3D-CT) images of human faces using multidetector computed tomography (MDCT). Methods: A total of 395 adults (232 men and 163 women) were enrolled and the 3D-CT images of their faces were reviewed in this study. In this study, the data from the images included the presence, shape, width and distance from the nasion to the supraorbital foramina/notches. ANOVA was used to assess the main effects of gender and side (right or left foramen/notch), and comparisons of the means were done by paired t-test. Results: The most common shapes in Koreans were a single notch (39.5%) on the right hand side and a single foramen (42.3%) on the left hand side. The incidence of a single foramen in Koreans was high compared to other races. The mean foramen diameter was $2.34{\pm}0.78$ mm, and the mean distance from the nasion was $27.19{\pm}4.03$ mm. The mean notch diameter was $3.37{\pm}1.71$ mm, and the mean distance from the nasion was $23.42{\pm}2.45$ mm. Conclusions: This is the first study on the variations of supraorbital foramina/notches in Koreans using 3D-CT images of faces. The anatomic characteristics of the supraorbital foramina/notch will help in performing nerve blocks and maxillofacial surgery.
