The purpose of this study was to investigate the functional changes of the vastus medialis while the neuromuscular electrical stimulation(NMES) was performed in elderly women with knee osteoarthritis. The subjects of this study were 30 women who were diagnosed degenerative arthritis, 15 in the experimental group and 15 in the control group. The experimental group performed conventional physical therapy and neuromuscular electrical stimulation, and the control group received only conventional physical therapy, five times per week for four weeks. Outcome measures were assessed before and after 4weeks using the VAS(pain), quadriceps femoris strength, thigh circumference, and Q-angle. The data of the quadriceps femoris strength and thigh circumference were significantly increased in experimental group(p<0.05). The data the pain was significantly decreased in both the two groups(p<0.05). There were statistically significant differences in quadriceps femoris strength and thigh circumference between the two groups(p<0.05). As the result, the application of neuromuscular electrical stimulation of the vastus medialis could be more effective for decrease pain and improving muscle function in patients with knee osteoarthritis.

This study was to investigate whether a trunk correction taping plus scapular setting exercises has an effect on trunk muscle activation and trunk balance and upper extremity function in patients with stroke. Twenty stroke patients were randomly divided into a trunk correction taping with scapular setting exercise group (n=10) and a scapular setting exercise group (n=10), and each group performed given interventions for 30 minutes for 4 weeks. In the experimental group, there were significant increases in muscle activation, K-TIS, and MFT (p<.05), and a significant improvement was detected in K-TIS and MFT compared to the control group (p<.05). This study suggests that a trunk correction taping with scapular setting exercises was more effective on trunk muscle activation, trunk balance, and upper extremity function in stroke patients compared to a scapular setting exercise. It could be clinically more significant if the change in the onset time of muscle activity is confirmed in the further researches.

This study describes conditions for the mass production of mutant hairy root lines by co-cultivation with A. rhizogenes harboring the activation tagging vector pHC7. Various sources of explants were subjected to genetic transformation with A. rhizogenes to determine optimum conditions and cultivar for the highest frequency of hairy root formation on explants. Hairy root formation also were investigated in transformed hairy roots grown in various culture media. Finally, a total of approximately 2,500 lines of hairy root mutants were produced in this study. A managing system for metabolomics in hairy root lines also were established. These hairy root lines will be useful to determine functions of genes relating biosynthesis pathway of secondary metabolites.

The purpose of this study was to compare the oralmyofunctions (occlusal force, tongue pressure, lip force) of adults and elderly people. And analyzed the factors affecting oral health related quality of life and dysphagia. The study was conducted on 73(over 20 years of age) Residing in Daejeon and Nonsan From December 2017 to May 2018. The data was analyzed using one-way ANOVA, pearson's correlation and multiple regression. The masticatory strength of each age group evaluated the right and left posterior occlusal forces. the elderys group (8.93, 10.80) were lower than adults group(12.51, 14.61) and middle age group(11.63, 14.75)(p>0.05). The tongue pressure was statistically significant lower in eldery group(37.43) than the adult group(60.55), middle-aged group(50.61) (p=0.000). In addition lip force was significantly lower in eldery group(8.57) than adult(12.01), middle-aged(11.37)(p= 0.000). The tongue pressure was positively correlated with the number of natural teeth(r=.566, p<.05), and the lip force (r=.497, p<.05). The quality of life quality related to oral health and dysphagia was tongue strength(p<0.05). It is necessary to recognize the risk of declining oral muscle function caused by aging. especially tongue strength is associated with quality of life and dysphagia. In order to improve the quality of life related to oral health in the aged society, the necessity of regular oral administration and oral muscle training was proposed.

The incidence of rotator cuff tear is increasing rapidly due to the aging of the population and the advancement of radiological diagnosis, and so on. Recently, arthroscopic rotator cuff repair is common way of surgery, and the surgical outcome is comparable to open rotator cuff repair. Arthroscopic repair is one of the minimally invasive procedures itself and may have additional benefits of postoperative pain reduction and early functional recovery. Recently, there has been increasing interest in various methods for improving the functional recovery of patients after arthroscopic shoulder surgery. Various protocols of functional recovery after arthroscopic shoulder surgery are classified by the postoperative period, and they are being studied actively and improved at each stage. On the other hand, there are a range of methods according to the postoperative period, rehabilitation stage, characteristics of individual patients, degree of rotator cuff tear, and underlying disease. Therefore, for functional recovery after arthroscopic rotator cuff repair, it is essential to establish proper regimens for functional recovery.
