  • PURPOSE: This study was conducted to investigate the effect of gluteal muscle strengthening exercises (GMSE) with ankle joint pumping exercises (AJPE) on thigh swelling, gait ability, and pain level in patients who underwent total hip arthroplasty. METHODS: A total of 38 patients who had undergone total hip replacement surgery >1 week prior participated in this study. Participants were randomly assigned to a group that performed only GMSE (CG; n = 19) and a group that performed GMSE and AJPE (EG; n = 19). The CG group performed GMSE for 30 min, and the EG group performed GMSE for 30 min followed by AJPE for 15 min. Exercises were performed five times a week, for a total of 20 times over 4 weeks in both groups. Thigh swelling (thigh size), 10 m walking test (10MWT) and timed up and go test (TUG) results, pain level (visual analogue scale, VAS) scores, Short Form 36 health survey (SF-36), and hip outcome scale (HOS) scores were evaluated before and after the intervention. RESULTS: After 4 weeks of intervention, significant differences were observed in the thigh size, 10MWT, TUG, VAS, SF-36, HOS before and after intervention in both groups (p < . 05). However, only thigh size showed a significant interaction between group and measurement time (p < . 05). CONCLUSION: GMSE combined with AJPE might be effective in improving the gait ability and pain level in patients with total hip arthroplasty, and GMSE may be more effective in improving thigh swelling and gait ability than GMSE without AJPE.

  • This study investigates the flexural behavior and strengthening performance of RC beams strengthened by prestressed CFRP laminates through static bending tests. Tests on RC beams strengthened with prestressed CFRP laminates were carried out for both cases where the CFRP laminates were bonded or not and the corresponding effects on the strengthening performances of RC beams were examined. Experimental results revealed that RC beams strengthened with prestressed CFRP laminates presented increased crack load and yield load according to the level of prestress. Premature debonding occurred before the RC beam strengthened with bonded prestressed CFRP laminates reaches the maximum load, and the specimen presented similar behavior to the one exhibited by the specimen with unbonded laminates.

  • Carbon fiber sheets are widely used for strengthening the deteriorated RC structures. However most studies on the strengthening method of RC structures with carbon fiber sheets are concerning static problems. The purpose of this experimental study is to present the basic data on fatigue behaviors of. RC beams strengthened with carbon fiber sheets. The experimental parameters of this study are ; 1) the existence of U-shaped carbon fiber sheets at the ends for anchoring, 2) the number of carbon fiber sheet layers in strengthening the RC beams, 3) the load levels of $60\%\~90\%$ of the static bending moment strength, which is obtained form the static tests. Experimental results are estimated from the relationships of load level, displacement, number of repeated load and released energy. It is concluded that U-shaped carbon fiber sheets for end anchoring is very effective and the beams strengthened with one layer of carbon fiber sheet have longer fatigue life than that with three layers.

  • The addition of steel fiber with concrete significantly improves the engineering properties of structural members, notably shear strength. The purpose of this study is to determine the steel fiber shape, aspect ratio and volume fraction ratio in a point of practical usage as structural members. Steel fiber factor and volume fraction are also considered to verify the strengthening effect in member level. From the reviewing of previous researches and analyzing of consecutive material test results, the optimum shape and length of steel fiber, which can have a good strengthening effects were defined as a hooked end type and larger than 1.5 times of maximum gravel size. Analyzing the test results of strength and deformation capacity, aspect ratio 75 and volume fraction $1.5\%$ can be having a maximum strengthening effect of steel fiber. Also steel fiber factor, tensile splitting strength, and flexural strength are found as key parameter in shear strengthening effect in member level.

  • PURPOSE: The purpose of this study is to examine how task-oriented training focused on lower extremity strengthening can affect mobility function and postural stability. METHODS: The study's subjects included 10 children with cerebral palsy: 7 girls and 3 boys between the ages of 4 and 9 whose Gross Motor Functional Classification System (GMFCS) level was I or II. Their functional mobility was gauged using the Gross Motor Function Measurement (GMFM), and their postural stability was evaluated using a force platform. Participants received task-oriented training focused on lower extremity strengthening for 5 weeks. The study used a paired t-test to investigate the difference in mobility function and postural stability of children with cerebral palsy before and after the lower extremity strengthening exercise. RESULTS: The GMFM dimensions D (standing) (p<.02) and E (walking) (p<.001) improved significantly between the pre-test and post-test. A significant increase in the posturographic center of pressure (CoP) shift and surface area of the CoP were found overall between the pre-test and post-test (p<.001). CONCLUSION: The present study provides evidence that an 8-week task-oriented training focused on strengthening the lower extremities is an effective and feasible strategy for improving the mobility function and postural stability of children with cerebral palsy.

  • This paper provides the results of an experimental investigation into the flexural behavior of continuous two-span unbonded post-tensioned high strength concrete (HSC) beams, strengthened by end-anchored CFRP laminates of different configurations in the hogging region. Implementing two different configurations of end-anchorage systems consisting of steel plates and bolts and carefully monitoring the development of strains throughout the load history using sufficiently large number of strain gauges, the response of beams including the observed crack propagations, beam deflection, modes of failure, capacity enhancement at service and ultimate and the amount of moment redistribution are measured, presented and discussed. The study is appropriate in the sense that it covers the more commonly occurring two span beams instead of the simply supported beams investigated by others. The experiments reconfirmed the finding of others that proper installation of composite strengthening system is most important in the quality of the bond which is essential for the internal transfer of forces. It was also found that for the tested two span continuous beams, the capacity enhancement is more pronounced at the serviceability level than the ultimate. This is an important finding as the design of these beams is mostly governed by the serviceability limit state signifying the appropriateness of the suggested strengthening method. The paper provides quantitative data on the amount of this capacity enhancement.

  • This study attempts to develop an interim evaluation system for the Integrated Rural Village Cluster Development Project(IRVCDP) which can secure its identity and sustainability, and induce its early settlement, and to derive plans for its steady progress. The evaluation system consists of three levels. The highest-order level is evaluation purposes, which describe IRVCDP's goals. They are expansion of income bases(EIB), improvement of living environments(ILE), strengthening of regional capabilities(SRC) and constructing effective project operation system(CEPOS). The second level is evaluation items, which each characterize the relevant evaluation purposes. The last level is evaluation indices, which observe achievement f3r evaluation purposes. 22 evaluation indices are selected to satisfy the purposes of this study through a brainstorming process and a survey on opinions of experts for those evaluation purposes and evaluation items which are derived from analyzing the IRVCDP's properties. The relative importance of the evaluation indices selected are determined through the AHP analysis. The most intriguing result from the AHP analysis is that strengthening of regional capabilities is found to be the most important one among evaluation purposes. It can be said that this result is parallel to a ultimate goal of the IRVCDP.
