Purpose: This study attempts to identify the effects of stretching and core exercise using proprioceptive neuromuscular facilitation (PNF) on the pain and functional disability index of patients with chronic lower back pain. Methods: A total of 20 patients with chronic lower back pain were randomly divided into either the experimental group (n=10), who received PNF stretching and core exercise, or the control group (n=10), who received conventional physiotherapy. Both interventions were applied three times a week for six weeks. The visible analogue scale (VAS) was measured in order to determine the level of pain, while the Oswestry Disability Index (ODI) was used to measure the change in the functional disability index. We conducted a paired t-test to compare the within-group change before and after the intervention. To compare the between-group difference, we used an independent t-test. The statistical significance level was set at ${\alpha}=0.05$ for all the variables. Results: The experimental group showed a significant within-group change in both the VAS and the ODI (p<0.01). The control group also showed a significant change (p<0.01). A significant difference was observed between the experimental group and the control group with regard to the change in both the VAS and the ODI after the interventions (p<0.01). Conclusion: In this study, the application of stretching and core exercise using PNF for subjects who complain of chronic lower back pain proved effective in reducing both pain and functional disability. We therefore expect that this intervention can be applied in the future as a useful program for patients with chronic lower back pain.

Purpose: The purpose of this study was both to examine the effects of proprioceptive neuromuscular facilitation (PNF) lower leg taping and treadmill training on the gait and balance abilities of patients with hemiplegia resulting from a stroke and to provide a taping method based on the PNF concept. Methods: Twenty patients with hemiplegia resulting from a stroke were randomly and equally assigned to a control group (n=10), which received treadmill training, and to an experimental group (n=10), which received PNF lower leg taping and treadmill training. The intervention was conducted five times per week for six weeks. In order to measure changes in the gait ability of the subjects, a 10-meter walking test (10MWT) and a 6-minute walking test (6MWT) were conducted, and in order to measure changes in the subjects' balance ability, a timed up and go test (TUG) was performed. In order to compare differences within each group before and after the intervention, a paired-t test was carried out, and in order to compare differences between the two groups, the analysis of covariance was utilized. All statistical significance levels were set at ${\alpha}=0.05$. Results: There were significant differences before and after the intervention within both groups in changes of 10MWT, 6MWT, and TUG (p<0.01). Regarding differences between the two groups, the experimental group underwent more effective changes than the control group in 6MWT and TUG (p<0.05). Conclusion: This study applied PNF lower leg taping and treadmill training to patients with hemiplegia resulting from a stroke, and this resulted in improvement in the subjects' gait and balance abilities. Taping and treadmill training based on the PNF concept is considered to be usefully applied as one of the programs to improve hemiplegic patients' gait and balance abilities.

Purpose: The purpose of this study is to examine the effects of proprioceptive neuromuscular facilitation (PNF) exercises on the neck disability index and deep neck flexor endurance of acute whiplash injury patients and to provide basic data for PNF exercises for musculoskeletal system disorder patients. Methods: Twenty acute whiplash injury patients were randomly assigned to an experimental group (n=10) and were treated with PNF exercises whereas a control group (n=10) underwent general exercises. Each session lasted 15 minutes and was performed five times a week for two weeks. The degree of pain was assessed using a visual analogue scale (VAS) and the degree of neck disability was measured by the neck disability index (NDI). Craniocervical flexor endurance (CCFE) tests were conducted to measure deep neck flexor endurance. Results: In terms of the intragroup changes in VAS, NDI, and CCFE, there were significant decreases in both the experimental and the control groups. After intervention, there were significant differences between the experimental group and the control group in terms of intergroup changes in VAS, NDI and CCFE. Conclusion: Although the exercises that are generally applied to acute whiplash injury patients are effective on the whole, PNF exercises are considered to be beneficial, given the improvements in the neck disability index and deep neck flexor endurance.

Rusgtib형 MSMPR 반응기와 쿠에트-테일러 반응기에서 이산화탄소와 수산화칼슘의 기-액 반응에 의해 생성되는 탄산칼슘 결정화에 대해 체류시간, 교반속도, 계면활성제의 종류와 같은 조업변수가 미치는 영향에 대해 실험적으로 연구하였다. 온도와 농도가 일정한 MSMPR 반응기에서는 계면활성제의 종류가 평균 입자크기에 가장 큰 영향을 미치는 것으로 나타났고, 이를 평균 제타전위로 수치화하였다. 교반속도의 증가에 따른 평균 입자크기는 물질전달 저항의 감소로 인해 증가하였다. 쿠에트-테일러 반응기에서는 와류 흐름의 효과는 기-액 반응성 탄산칼슘 결정화에 대해 독특한 특성을 나타내였다. 쿠에트-테일러 반응기에서는 와류에 의해 균일한 혼합조건을 얻을 수 있었고, 이로 인해 MSMPR 반응기의 경우보다 입자의 크기분포가 매우 균일하게 나타났다. The effect of the operating variables such as mean residence time, agitational speed and surfactant type, on the precipitation of calcium carbonate was experimentally investigated in MSMPR and Couette-Taylor reactors. The precipitates was produced by the gas-liquid reaction of CO₂gas and Ca(OH)₂aqueous solution. Under fixed temperature and concentration in MSMPR reactor, it was founded that the surfactant type had the greatest influence on the mean particle size and this effect was represented numerically by the zeta potential. With increasing the impeller speed the mean particle size increased due to decrease of the resistance in mass transfer processes. The vortex flow in Couette-Taylor reactor affected the precipitation of calcium carbonate complicatedly. The homogeneous mixing owing to Taylor vortex in Couette-Taylor reactor led to the more uniform particle size distribution than that in MSMPR reactor.
