Background: Functional massage is a therapeutic massage that incorporates joint motion in non-end-range to reduce pain and improve range of motion (ROM) in patients. This study was aimed at investigating the immediate effect of functional massage on pain, range of motion, balance ability and, gait speed of patients having undergone total hip replacement. Methods: Twenty patients were treated by one participating orthopedic manual physical therapist and randomly assigned to the control group (n=10) or the experimental group (n=10). To treat patients of each group, functional massage and range of motion exercises were used. The experimental group received a functional massage and the control group received range of motion exercise for minutes for one session. The visual analog scale was used for pain assessment. Balance ability was measured using a timed up and go test and a one-leg standing test for patients. The 10-meter walk test was used for the measurement of gait speed assessment of patients. Results: Significant improvements were observed in terms of balance ability (p<.05), gait speed (p<.05), and ROM (p<.05) after functional massage. There was no significant inter-group difference (p>.05). Conclusion: Application of the functional massage showed that statistically significant improvements in ROM, gait speed, and balance ability after a single treatment session. This technique may be a useful treatment in patients having undergone total hip replacement.

In this research, with a goal of lessening the damage to hair by adding rose hip extract to permanent wave 1 solution and performing permanent wave procedure prior to acid dyeing and maximizing the effect of the procedure, rose hip extract 15%, 20% was added to each thioglycolate 1 solution and cysteine 1 solution and the procedure was performed. As a result, when performing the procedure by adding rose hip extract to permanent wave 1 solution thioglycolate and cysteine permanent wave 1 solution, the effect of wave effectiveness is increased and the damage to hair was confirmed to be low. Depending on the rose hip additive status in thioglycolate, the treatment effect of hair was shown to be beneficial. However, the limit of this research is that the thickness of hair strands for each person differs as well as the location of the hair contributing to the difference and therefore exact judgement regarding the shape of waves as well as the level of damage cannot be fully measured. In the following clinical tests, we will test the procedure on variety of hair types.

Purpose: This study was conducted to compare cemented and cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures via meta-analysis and systematic review of relevant studies. Materials and Methods: Systematic review and meta-analysis were performed on 31 available clinical studies; 19 of these studies used cemented stems, 12 used cementless stems, one used both types of stems, and two studies involved a comparative analysis of both stem types. Results: There were statistically significant differences in rates of leg length discrepancy (LLD) greater than 1 cm between the cemented (event rate, 0.089) and cementless groups (event rate, 0.015 and 0.047; P=0.03). Conclusion: Cemented bipolar hemiarthroplasty and cementless bipolar hemiarthroplasty performed on elderly patients with unstable intertrochanteric fracture revealed similar mortality and complication rates; however, the rate of LLD greater than 1 cm was significantly higher in the cemented group compared with the cementless group.

The microstructure of $ZrO_2$ toughened $Al_2O_3$ ceramics was carefully controlled so as to obtain dense and fine-grained ceramics, thereby improving the properties and reliability of the ceramics for capillary applications in semiconductor bonding technology. $Al_2O_3-ZrO_2(Y_2O_3)$ composite was produced via Ceramic Injection Molding (CIM) technology, followed by Sinter-HIP process. Room temperature strength, hardness, Young's modulus, thermal expansion coefficient and toughness were determined, as well as surface strengthening induced by the fine grained homogenous microstructure and the thermal treatment. The changes in alumina/zirconia grain size, sintering condition and HIP treatment were found to be correlated.

The operating temperature has been increased to improve the efficiency of gas turbine. The most advanced Gas turbine is operated at above $1,500^{\circ}C$. Improvement in material and cooling method permit hot gas path component to run at increased temperature. But, the repair of blades which are developed with advanced manufacture technique is difficult to use normal welding. Most of gas turbine blades are made of precipitation harden nickel base superalloy, which is very hard to weld. Therefore, the employment of welding filler on blade is solid solution nickel base superalloy(Hastelloy X, Inconel 617). In this study, Tensile test in high temperature was conducted on welded GTD111DS with GTD111 to evaluate effect of variation of pre, post treatment. The result of this study showed that the specimen was treated with optimum pre and post treatment(preweld HT($1200^{\circ}C$), Post treatment($1100^{\circ}C$ HIP, $1200^{\circ}C$ + $1100^{\circ}C$ + $800^{\circ}C$ HT) is mush superior.

Background: In South Korea, 22.3% of women ${\geq}50years$ of age and 37% of women ${\geq}70years$ of age visit the doctor to obtain treatment for osteoporosis. According to the analysis of the National Health Insurance Services claim data between 2008 and 2012, the number and incidence of hip and vertebral fractures increased during the same period. Denosumab, a newly marketed medicine in Korea, is the first RANK inhibitor. Methods: A cost-utility analysis was conducted from a societal perspective to prove the superiority of denosumab to alendronate. A Markov cohort model was used to investigate the cost-effectiveness of denosumab. A 6-month cycle length was used in the model, and all patients were individually followed up through the model, from their age at treatment initiation to their time of death or until 100 years of age. The model consisted of eight health states: well; hip fracture; vertebral fracture; wrist fracture; other osteoporotic fracture; post-hip fracture; post-vertebral fracture; and dead. All patients began in the well-health state. In this model, 5% discounted rate, two-year maximum offset time, and persistence were adopted. Results: The total lifetime costs for alendronate and denosumab were USD 5,587 and USD 6,534, respectively. The incremental cost-effectiveness ratio (ICER) for denosumab versus alendronate was USD 20,600/QALY. Given the ICER threshold in Korea, the results indicated that denosumab was remarkably superior to alendronate. Conclusion: Denosumab is a cost-effective alternative to the oral anti-osteoporotic treatment, alendronate, in South Korea.
