Stress fractures are common injuries that begin with repetitive and excessive stress on the bone. It is very rare that stress fracture was occurred in pubis superior ramus in athletics, and the report concerning the exercise therapy for this fracture was not sufficient in the literature. We report of a case of a 17-year-old male soccer player who suffered from left inguinal pain due to the stress fracture of pubis superior ramus. He was conducted an exercise program that consisted of muscle strength, stretching, aerobic and functional exercise for 2 months. After this intervention, all muscle strength was significantly improved (17%) compared to baseline data, and also flexibility and range of motion were improved. This case shows that exercise therapy considered the cause and cyclic formation of bone remodeling is benefit to improve the exercise performance for a soccer player with superior ramus stress fracture.

Left ventricular assist devices (LVADs) are a treatment option for patients with severe chronic heart failure. These patients are referred to an inpatient cardiac rehabilitation after implantation to improve an aerobic capacity and quality of life (QOL). Several studies have reported that an exercise therapy, which is a component of cardiac rehabilitation, improves exercise capacity and QOL. The LVADs were implanted successfully in a destination therapy in two Korean patients, and these patients were enrolled in the cardiac rehabilitation. After an individualized intervention, they were discharged from improved exercise functional capacity and QOL. This is the first report showing a benefit of the individualized exercise therapy using different parameters after LVADs implantation in Korea.

저온($320^{\circ}$C)에서 $SiH_4$와 $N_2O$ 가스의 혼합을 통해 플라즈마화학기상증착(PECVD)법을 이용하여 실리카 광도파로의 클래딩막으로 사용되는 $SiO_2$ 후막을 제조하였으며, 공정변수로는 $N_2O/SiH_4$ 유량비와 RF power에 변화를 주었다. 증착된 시편은 $N_2$ 분위기의 열처리로에서 $1050{\circ}$에서 2시간동안 열처리하였다. $N_2O/SiH_4$ 유량비가 증가함에 따라 증착속도는 $9.4~2.9{\mu}m /h$까지 감소하였으며, RF power가 증가함에 따라 증착속도는 $4.7~6.9{\mu}m /h$까지 증가하였다. 두께 및 굴절률은 Prism Coupler를 이용하여 분석하였다. 화학적 성질 및 구조적 성질은 X-ray Photoelectron Spectroscopy(XPS)와 Fourier Transform-Infrared Spectroscopy(FT-IR)를 이용하여 분석하였으며, Scanning Electron Microscopy(SEM)를 이용하여 시편의 단면을 관찰하였다. Silicon dioxide thick film using silica optical waveguide cladding was fabricated by Plasma Enhanced Chemical Vapor Deposition(PECVD) method, at a low temperature ($320^{\circ}$C) and from $(SiH_4+N_2O)$ gas mixtures. The effects of deposition parameters on properties of $SiO_2$ thick films were investigated by variation of $N_2O/SiH_4$ flow ratio and RF power. After the deposition process, the samples were annealed in a furnace at $1150^{\circ}$C, in N2 atmosphere, for 2h. As the $N_2O/SiH_4$ flow ratio increased, deposition rate decreased from 9.4 to 2.9 ${\mu}m/h$. As the RF power increased, deposition rate increased from 4.7 to 6.9 ${\mu}m/h$. The thickness and the refractive index measurements were measured by prism coupler. X-ray Photoelectron Spectroscopy(XPS) and Fourier Transform-infrared Spectroscopy(FT-IR) were used to determine the chemical states. The cross-section of films was observed by Scanning Electron Microscopy(SEM).

The purpose of this research is to prepare exercise stability/safety by predicting possible dangerous situations during competitions in advance and presenting appropriate exercise intensity based on TCD(Transcranial Doppler ultrasound) analysis of Systolic, Diastolic and Mean Blood Flow Velocity, Pulsatility Index(PI) and Resistive Index(RI) from MCA according to exercise intensity as well as at rest. The subjects were 10 soccer players from high school over 5 years in experience. To analyze Cerebral Blood Flow, PI and RI Changes according to exercise intensity, treadmill test was performed among single group at rest and with moderate, high and maximal intensity. In comparison with the velocities at rest, Systolic, Diastolic and Mean Blood Velocity were increased at moderate and high intensity but they were decreased at maximal intensity(p<0.05). On the other hand, Pulsatility and Resistive Index were increased at all the other intensities(p<0.05). In a repeated measured One-way ANOVA, there were significant differences between the each measured values-blood velocities and indexes-and the various exercise intensities (p<0.05). In a post Hoc test, there were significant differences between rest and the other intensities in Systolic Blood Velocity ; rest and moderate/high intensity, moderate and maximal intensity, and high and maximal intensity in Diastolic Blood Velocity ; rest and moderate/high/maximal intensity, and high and maximal intensity in Mean Blood Velocity ; rest and moderate/maximal intensity, and moderate and high intensity in Pulsatility and Resistive Index (p<0.05).

Purpose: This study aims to compare and analyze the effect of a 12-weke corrective exercise program on the structural variables of spinal curvature, neck disability index and balance ability in patients with flat back. Method: In this study, 24 patients with flat back participated, and they were randomly divided into three group; corrective exercise group (CEG: n=8), resistance exercise group (REG; n=8), and physical therapy group (PTG: n=8). The CEG and REG performed corrective exercise3 times per week and 70 minutes at a time for 12 weeks and REG conducted the exercise with thera-band. The variables of spinal curves included cervical lordosis, thoracic kyphosis, and lumbar lordosis were measured by X-ray test. The function of the neck was checked using a questionnaire with a neck disability index. The balance ability was measured by a balance machine and the test was conducted before and after exercise intervention for 12 weeks. Results: The results of this study are as follows. The cervical lordosis angle showed significant differences in both group and period, interactions p(<.001). Significant differences were found in CEG p(<.001), at each group period, (p<.05) in the groups (p<.001), as a result of paired t-test, REG and PTG, and in CEG and PTG (p<.001) post-testing. Thoracic kyphosis angle showed significant differences in both group and period, interactions (p<.001). Significant differences were found in CEG (p<.001), at each group period (p<.01) in the groups (p<.05), as a result of paired t-test, REG and PTG, and in CEG and PTG (p<.001) post-testing. The lumbar lordosis angle showed significant differences in both group and period, interactions (p<.001). Significant differences were found in PTG (p<.001) and CEG (p<.001) levels in each group, and (p<.001) levels between groups. As a result of paired t-test, REG and PTG, and in CEG and PTG (p<.001) post-testing. The neck disability index showed significant differences in both group and period, interactions(p<.001). At the time of each group, there were significant differences in PTG (p<.05), REG (p<.01), and CEG (p<.001) levels. Between groups (p<.001), there was a significant difference between CEG and PTG as a result of post-mortem examination (p<.05). The balance ability was found to be significant in the interaction between group and timing, timing (p<.001), and group main effect (p<.05). In each group period, significant differences were found in REG (p<.01), among groups (p<.001), compared with REG and PTG, and compared with CEG and REG (p<.01). Conclusion: The corrective exercise program is a more effective exercise intervention than resistance or physical therapy on the spinal curvature and the improvement of spinal curvature was associated with improving neck function and the ability of body balance although resistance exercise showed improvement of these variables. Therefore, corrective exercise is recommended as the most effective intervention to improve spinal curve, neck function, and the ability of body balance in patients with flat back.
