  • At present, CHS(Compression Hip Screw) is one of the best prosthesis for the intertrochanteric fracture. There is nothing to evaluate the CHS itself with the finite element analysis and mechanical tests. They have same ways of the experimental test of the ASTM standards. The purpose of this study is to evaluate the existing CHS and the new CHS which have transformational design factors with finite element analysis and mechanical tests. The mechanical tests are divided into compression tests and fatigue test for evaluating the failure load, strength and fatigue life. This finite element method is same as the experimental test of the ASTM standards. Under 300N of compression load at the lag screw head. There are less differences between Group (5H, basic type) and Group which has 8 screw holes. However, there are lots of big differences between Group and Group which is reinforced about thickness of the neck range. Moreover, the comparison of Group and Group shows similar tendency of the comparison of Group and Group . The Group is reinforced the neck range from Group. After the experimental tests and the finite element analysis, the most effective design factor of the compression hip screws is the reinforcement of the thickness, even though, there are lots of design factors. Moreover, to unite the lag screw with the plate and to analyze by static analysis, the result of this method can be used with experimental test or instead of it.

  • Objectives This study was performed to investigate the effects of Saengkanggamchotang (SKT) on the monosodium iodoacetate (MIA) induced osteoarthritis in rats. Methods Osteoarthritis was induced by injection of MIA (50 ul, 60 mg/ml) into knee joints of rats. Rats are divided into a total of 4 groups (normal, control, positive comparison group, SKT treated group, each n=6). Normal group are not treated at all without inducing osteoarthritis whereas control group were induced for osteoarthritis by MIA and oral medicated with 20 ml of distilled water per day. Positive comparison group was injected with MIA and after 7 days, that was taken indomethacin (30 mg/kg/mouse). SKT treated group was injected with MIA and after 7 days that was taken SKT (30 mg/kg/mouse). Positive comparison group and SKT treated group were oral medicated for each substance a total of 4 weeks with one time per day. After experiments (from 1 week after injection of papain to 4 weeks elapsed), the functions of liver and kidney, Prostaglandin E2, inflammatory cytokine (IL-$1{\beta}$, IL-6, TNF-${\alpha}$), osteocalcin, TIMP-1, MMP-9 within serum. Knee joint structures were observed by H&E, safranin-O staining method, and amount of cartilage were measured by ${\mu}CT$-arthrography. Results 1) Hind paw weight bearing ability was significantly improved. 2) Functions of liver and kidney were not affected. 3) Prostaglandin E2, osteocalcin, TIMP-1, MMP-9 in serum were significantly decreased. 4) Inflammatory cytokine IL-$1{\beta}$ was significantly decreased, and IL-6, TNF-${\alpha}$ were decreased but had not significant. 5) In terms of histopathology, significantly reduced subsidence of cartilage and bone in H&E staining. And in Safranin O staining, proteoglycan content in synovial membrane was significantly increased compared with control group. 6) Destruction of cartilage on ${\mu}CT$-arthrography was significantly reduced. Conclusions Based on all results mentioned above, Saengkanggamchotang (SKT) is believed to be meaningful for suppressing the progress of osteoarthritis and its treatments.

  • Objective: The purpose of this study was to investigate the effect of foot strengthening exercise program and functional insoles on joint angle and plantar pressure in elderly women. Thirteen elderly women who were enrolled in a university senior citizens academy of a metropolitan city in 2017 were divided into two groups: exercise group with functional insole (n=7) and exercise group without functional insole (n=6). Method: Three-dimensional motion analysis and Pedar-X were performed to compute the joint angle and the foot plantar pressure, respectively. Two-way repeated measure ANOVA was conducted to compare dependent variables within and between groups. The significance level was set at ${\alpha}=.05$. Results: The range of motion (ROM) of the ankle, knee, and hip joints in the exercise group with functional insole increased significantly more than the exercise group without functional insole. In both the experimental group and the comparison group, the maximum foot plantar pressure and the mean foot plantar pressure were decreased, but the comparison group without functional insole showed more decrease. Since the experimental group demonstrated greater pressure than the comparison group in the contact area (forefoot, midfoot), it was distributed over a greater area. Conclusion: The results of this study suggest that participation in foot strengthening exercises and using a functional insole has more positive effects than foot strengthening exercises alone on the joint angle and plantar pressure in elderly women. Increased foot plantar pressure led to an increased contact area (forefoot, midfoot) for distribution of the foot plantar pressure, but the effect of reducing the maximum and average plantar pressures was incomplete. However, wearing functional insoles along with exercise, could help in improving the stability of the joints, by increasing the range of motion, and could help the elderly in movement of the muscles more effectively, leading to an improvement in gait function.

  • This study aimed to develop a peer-assisted learning (PAL) program for use in a core nursing skills education course and to investigate the effects of the education program on three key outcomes. A comparative study was conducted through the division of students of a core nursing skills education program into a treatment group and control group. After the programs, self-efficacy, confidence and satisfaction were compared between the groups. The comparison of these three factors indicated that the related scores were significantly higher in the treatment group receiving the education program with the PAL method than those of the control group receiving traditional education. We concluded that self-efficacy gave the nursing students the confidence that they could successfully perform their tasks and motivation to learn. Education programs using the PAL method are suggested as an effective method for the acquisition of skills among nursing students.
