We propose the representation of a improved dynamic object-oriented program dependence graph so as to process the slicing of object-oriented programs that is composed of related programs in order to process certain jobs. We also propose an efficient slicing algorithm using the relations of relative tables in order to compute dynamic slices of object-oriented programs. We programmed the algorithm by using fortran and Visual C++. The procedure that computes the dynamic object-oriented program slices using the improved dynamic object-oriented program dependence graph(IDOPDC) is divided into four steps. Consequently, the efficiency of the proposed improved dynamic object-oriented program dependence graph(IDOPDG) technique is also compared with the dependence graph techniques discussed previously. As a result, this certifies that an improved dynamic object-oriented program dependence graph is more efficient in comparison with the traditional dynamic object-oriented program dependence graph(DOPDG).

Purpose : The most effective intervention for flat foot is strengthening exercises for the intrinsic and extrinsic of the foot. Additionally, visual feedback is necessary for movement accuracy. However, the effectiveness of the intervention when combined with visual feedback was not revealed. To confirm this, the research was to investigate the effect of visual feedback and a complex exercise program on navicular bone height, plantar pressure, and lower extremity alignment. Methods : The twenty eight adult men and women with flat foot were randomly assigned to group 1 (n=14) and group2 (n=14), group1 performed complex exercises with visual feedback, and group 2 performed only complex exercises. Both groups performed a 40 minute compound exercise program three times a week. Navicular drop test, plantar pressure test, and lower extremity alignment test were performed equally in both group. Results : As a result of comparing the change in navicular height within the group according to the intervention, both groups showed a significant difference before and after the exercise (p>.05). There was not significant difference comparing the difference between the groups in the navicular height (p>.05). Comparing the change in plantar pressure within groups, there was not significant difference in the change in plantar pressure in both groups (p>.05). Coparing the difference before and after exercise between groups, there was not significant plantar pressure (p>.05). Comparing the change in leg alignment within the group, there was a significant difference in the change in ankle before and after exercise in group 1 (p<.05), but there was not significant difference in group 2. There was not significant difference in pelvic tilt and knee tilt before and after exercise in both groups (p>.05). Comparing the before and after exercise difference between groups, there were not significant in all variables of leg alignment (p>.05). Conclusion : The results of this study showed that complex exercise applied to patients with flat foot were effective in increasing the height of the navicular bone and ankle angle, but there was no effect due to visual feedback.

Purpose: The purpose of this study was to determine the effects of bilateral visual feedback training with visual targets on the postural balance and fall efficacy of stroke patients with hemiparesis. Methods: A total of 24 stroke patients with hemiparesis were randomly assigned to either a bilateral visual feedback training (BVFT, n=8) group, unilateral visual feedback training (UVFT, n=8) group, or a control group (n=8). The BVFT and UVFT groups performed weight-bearing training on the bilateral (less-affected and affected side) or unilateral side (affected side) with visual feedback using visual targets. The control group performed squat training without visual feedback using visual targets. The training program was conducted in the form of 3 sets a day, 3 times a week, for 4 weeks. The participants were evaluated using the Berg balance scale (BBS), lateral reaching test (LRT), timed up and go test (TUG), and the activities-specific balance confidence scale (ABC). Results: In the intra-group comparison after the intervention, the BVFT group showed a significant difference in the BBS, TUG, affected and less-affected side LRT, and ABC (p<0.05). The UVFT group showed a significant difference in the BBS and ABC (p<0.05). In the inter-group comparison after the intervention, the BVFT group showed significant improvements in their BBS, affected side LRT, and TUG, when compared to the control group (p<0.05). Conclusion: These findings show that bilateral visual feedback training with visual targets during bilateral weight-bearing exercises can improve the postural balance function in stroke patients.

Purpose: To evaluate the effects on vision care program including traditional Korean treatment for elementary school students. Methods: 172 eyes of eighty-six older elementary students underwent a vision care program, including traditional Korean treatment, for 3 months between March 2010 and June 2010. The vision care program included health education, such as lifestyle modification, vision strengthening exercises and a course of treatment with traditional Korean methods. Traditional Korean treatment covered periocular acupuncture point stimulation, periauricular acupuncture point stimulation and herbal drug therapy. All patients were examined for visual acuity and auto-refraction and filled out a satisfactory questionnaire about ocular discomforts and quality of life before and after treatments. Results: Patients with mild myopia (-0.75~-2.00) were 61 (35.5%), and 46 (26.7%) were emetropia (${\pm}0.50$ or less). After treatment, uncorrected visual acuity in both eyes was $0.77{\pm}0.46$, which was lower than that before treatment ($0.82{\pm}0.51$), but corrected visual acuity was $0.98{\pm}0.21$, which was higher than that before treatment ($0.93{\pm}0.28 $). About the refractive change, the emetropia group showed a slightly myopic shift while the mild myopia group intended to reduce the myopic error. However, this was not statistically significant. The scales of eyeball pain or discomfort decreased significantly from $17.59{\pm}22.5$ before treatment to $10.28{\pm}17.80$ after treatment, and the scales of the quality of life increased from $1.85{\pm}1.25$ before treatment to $2.25{\pm}1.30$ after treatment. Most patients (90.7%) were satisfied with their treatment results. Conclusions: The vision care program including traditional Korean treatment for elementary school students was effective to improve corrected visual acuity in both eyes and delay the progression of school myopia. In addition, it helped to reduce eyeball pain and discomfort and ultimately to enhance quality of life. Long-term follow-up studies will be needed.
