Background: The purpose of this study was to investigate the effects of between modified mulligan technique and modified mulligan technique with taping on the active range of motion & passive range of motion, scapula index into the stroke patients. Methods: The subjects with stroke were randomly divided into two groups. Group 1 (n=9) was conducted modified mulligan technique and Group 2 (n=9) was conducted modified mulligan technique with taping week three times for 4weeks. Active range of motion (AROM), passive range of motion (PROM) and scapula index (SI) were measured by goniometer and tape measure. Wilcoxon signed-rank tests were used to compare differences before and after intervention. Mann-Whitney U-test were conducted to compare before to after intervention in the two groups. Results: AROM was significantly different both groups (p<.05) and between groups were not significantly different into pre and post intervention (p>.05). PROM was significantly different both groups (p<.05) however, between groups were not significantly different into pre and post intervention (p>.05). SI was significantly different only group 2 and between groups were not significantly different (p>.05). Conclusions: This study demonstrated effective bo-th modified mulligan technique and modified mulligan technique with taping on the active range of motion and passive range of motion. Because only modified mulligan technique with taping are effective on the scapula index we recommend modified mulligan technique with taping than modified mulligan technique.

Objective : Pedicle screw fixation for spine arthrodesis is a useful procedure for the treatment of spinal disorders. However, instrument failure often occurs, and pedicle screw loosening is the initial step of a range of complications. The authors recently used a modified transpedicular polymethylmethacrylate (PMMA) screw augmentation technique to overcome pedicle screw loosening. Here, they report on the laboratory testing of pedicle screws inserted using this modified technique. Methods : To evaluate pullout strengths three cadaveric spinal columns were used. Three pedicle screw insertion methods were utilized to compare pullout strength; the three methods used were; control (C), traditional transpedicular PMMA augmentation technique (T), and the modified transpedicular augmentation technique (M). After control screws had been pulled out, loosening with instrument was made. Screw augmentations were executed and screw pullout strength was rechecked. Results : Pedicle screws augmented using the modified technique for pedicle screw loosening had higher pullout strengths than the control ($1106.2{\pm}458.0N$ vs. $741.2{\pm}269.5N$; p=0.001). Traditional transpedicular augmentation achieved a mean pullout strength similar to that of the control group ($657.5{\pm}172.3N$ vs. $724.5{\pm}234.4N$; p=0.537). The modified technique had higher strength than the traditional PMMA augmentation technique ($1070.8{\pm}358.6N$ vs. $652.2{\pm}185.5N$; p=0.023). Conclusion : The modified PMMA transpedicular screw augmentation technique is a straightforward, effective surgical procedure for treating pedicle screw loosening, and exhibits greater pullout strength than traditional PMMA transpedicular augmentation. However, long-term clinical evaluation is required.

Once a submasseteric space infection is diagnosed, the key to resolving the infection is via surgical intervention to evacuate the pus. Although it is possible and occasionally practical to drain the submasseteric space via an intraoral approach, an extraoral approach may sometimes be required. Surgeons have encountered complications such as facial nerve damage during extraoral incision and drainage procedures, and they have felt that extraoral dissection was very difficult. As such, an easier and simpler technique is needed. Our department recently modified various drainage techniques for submasseteric space abscesses. Damage to the marginal branch of the facial nerve did not occur, and this technique was very simple and rapid, such that a novice physician could perform this procedure. This modified technique was possible with trismus and under local anesthesia. After intraorally checking the position of the drain, the intraoral wound is closed with an absorbable suture and the drain is fixed to the extraoral skin. When a masseteric space infection is diagnosed, multiple space involvement is ruled out, and dependent drainage is required, this modified drainage technique can be useful.

A preconditioning technique is presented for a simultaneous solution to wind-membrane interaction. In the simultaneous equations, a linear elastic model was employed to deal with the fluid-structure data transfer at the interface. A Lagrange multiplier was introduced to impose the specified boundary conditions at the interface and strongly coupled simultaneous equations are derived after space and time discretization. An initial linear elastic model preconditioner and modified one were derived by treating the linearized elastic model equation as a saddle point problem, respectively. Accordingly, initial and modified fluid-structure interaction (FSI) preconditioner for the simultaneous equations were derived based on the initial and modified linear elastic model preconditioners, respectively. Wind-membrane interaction analysis by the proposed preconditioners, for two and three dimensional membranous structures respectively, was performed. Comparison was made between the performance of initial and modified preconditioners by comparing parameters such as iteration numbers, relative residuals and convergence in FSI computation. The results show that the proposed preconditioning technique greatly improves calculation accuracy and efficiency. The priority of the modified FSI preconditioner is verified. The proposed preconditioning technique provides an efficient solution procedure and paves the way for practical application of simultaneous solution for wind-structure interaction computation.

In tins paper, a new DA(Distributed Arithmetic) tilter implementation technique has been proposed. Contrary to vertical directional calculation of input sample bit format in the conventional DA implementation technique, proposed implementation technique utilizes horizontal directional calculation of input sample bit format. Since proposed technique calculates in horizontal direction, it does not need ROM and utilizes the Modified Booth algorithm. Furthermore proposed technique can be applied to implement the variable coefficients filters in addition to the fixed coefficients filters. Using conventional and proposed techniques, a 20 tap filter is implemented by Verilog-HDL coding. Through Synopsis synthesis tool, it has been shown that 41.6% area reduction can be achieved.

Regression testing is a very costly process performed primarily as a software maintenance activity. It is the process of retesting the modified parts of the software and ensuring that no new errors have been introduced into previously tested source code due to these modifications. A regression test selection technique selects an appropriate number of test cases from a test suite that might expose a fault in the modified program. In this paper, we propose both a regression test selection and prioritization technique. We implemented our regression test selection technique and demonstrated in two case studies that our technique is effective regarding selecting and prioritizing test cases. The results show that our technique may significantly reduce the number of test cases and thus the cost and resources for performing regression testing on modified software.

Purpose: The purpose of this study was to evaluate the clinical outcome of a modified Kidner procedure using a suture bridge technique in symptomatic type II accessory navicular. Materials and Methods: Between January 2013 and December 2014, a total of 35 cases with symptomatic type II accessory navicular were treated with a modified Kidner procedure using the suture bridge technique. The patients were evaluated preoperatively, 3 months after surgery, and at the latest follow-up (at least six months postoperatively) clinically via the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS), and the self-subjective satisfaction score. Results: The mean AOFAS midfoot score demonstrated significant improvement from a mean of 45.3 preoperatively to a mean of 89.2 at 3 months after surgery. At the latest follow-up, the mean AOFAS midfoot score was 92.6 (p<0.001). The mean VAS also improved significantly, decreasing from 6.7 out of 10 preoperatively to 1.8 at 3 months after surgery. At the latest follow-up, the VAS was 1.2 (p<0.001). The mean time of a single-limb heel raise was 4.6 months postoperatively and the self-subjective satisfaction score was 1.4 out of 4 at the latest follow-up. Conclusion: The short-term surgical results of the modified Kidner procedure with a suture bridge technique for symptomatic type II accessory navicular were good to excellent in terms of pain, functional and clinical assessments. In conclusion, the modified Kidner procedure with the suture bridge technique is a reasonable treatment option for symptomatic type II accessory navicular.
