  • This study to investigate the effects of proprioceptive motor program on proprioceptive and balance ability for patients with chronic stroke. Twenty nine subjects were recruited by means of a convenience sampling from Gyeonggi-do B hospital. The subjects were divided into two group: a proprioceptive motor program and general physical therapy(n=15), general physical therapy(n=14). The stimulation and exercises were conducted for 30 min per day, three days, per week for six weeks. All participants were assessed before and after taping training using proprioceptive, berg balance scale(BBS), timed up and go test(TUG), and balance ability was measured using a BioRescue. After training, the change values of the proprioception and balance ability in experimental group were significantly greater than control group(p<0.05). This findings show that progressive and proprioceptive motor program training convergence can be effective for stroke patients proprioception and balance ability. Continued development of convergence interventions for chronic stroke patients with proprioception and balance ability in the practice are suggested.

  • The purpose of this study was to investigate the effects of Pilates exercises on the improvement of blood pressure and respiratory function. 36 subjects which were randomly divided into Pilates exercises group(n=18) and control group(n=18). Subjects in the Pilates exercises group were regularly participated in Pilates exercise program for 8 weeks. We were measured the blood pressure and respiratory function such as blood pressure, VO2max, METs, and Anaerobic threshold at before and after the experiment. After 8 weeks, in Pilate exercises group, there were significant improvement on blood pressure and respiratory function except the diastolic blood pressure. And subjects participated in Pilates exercise group were significantly improved compared to control group on systolic blood pressure, VO2max, METs, and Anaerobic threshold. But in control group, there were no significant differences. In conclusion, regular participation in Pilates exercises improved the blood pressure and respiratory function. These results suggest that Pilates exercise is the method that replace aerobic exercise.

  • This study was a systematic review and meta-analysis comparing the effects of aquatic exercise and land-based exercise in the treatment of knee osteoarthritis. 7 studies (n=449) met selection and exclusion criteria out of 287 potential studies obtained from the literature search via Ovid-Medline, Cochrane Library CENTRAL, CINAHL, RISS and KISS. The overall risk of bias of selected studies using SIGN (Scottish Intercollegiate Guidelines Network) checklist for randomized controlled trials (RCT) was regarded as low. As a result of meta analysis, Standardized Mean Difference (SMD) for pain was -0.26(95% CI -0.49, -0.03, p=0.03, $I^2=14%$), which implies that aquatic exercise groups had significant less pain than land-based exercise groups. On the other hand, there was no significant difference between aquatic exercise groups and land based exercise groups for flexion Range of Motion (ROM) (-0.12, 95% CI -0.51, 0.27, p=0.53, $I^2=0%$), extension ROM (-0.04, 95% CI -0.55, 0.48, p=0.89, $I^2=43%$), physical function (-0.12, 95% CI -0.44, 0.19, p=0.44, $I^2=0%$), Quality of Life (QOL) (-0.15, 95% CI -0.54, 0.24, p=0.46, $I^2=0%$). This study has some limitations due to few RCTs comparing aquatic exercise groups and land-based exercise groups in the treatment of knee osteoarthritis. Therefore, further RCTs should be conducted along with long-term outcomes.

  • The purpose of this study was to examine the effects of lumbar stabilization exercise using the PNF techniques on the lumbar deep muscles thickness and functional activity in chronic low back pain patient. Group I(n=10): general physical therapy group; Group II(n=10): general lumbar stabilization exercise group; Group III(n=10): lumbar stabilization exercise using PNF techniques(stabilizing reversal, rhythmic stabilization, combination of isotonic) group. Change of pain was measured with visual analog scale(VAS). To observe muscle thickness changes, we measured transverse abdominis(TrA), external oblique(EO), multifidus with real time ultrasound scanning. The functional activity were measured with Oswestry Disability Questionnaire(ODQ) and Roland & Morris Disability Questionnaire(RMDQ). In VAS test, group III had more significantly decreased than before exercise. In muscle thickness test, group III had more significantly increased than before exercise in right/left TrA, EO, multifidus. In ODQ & RMDQ test, group III had more significantly decreased than before exercise. This study show that the PNF techniques is effective in improving the lumbar stability and functional activity in chronic low back pain patients.

  • Globalization, deindustrialization, and the revolutionary development of technology has led to the concerns that existing social policies might not be fit for the current and upcoming society. At the same time, the idea of universal basic income has drawn significant attentions as the alternative to the old welfare state. There are pros and cons of basic income, and scholars of both sides stand against each other with their equivalently strong logics. In this situation, some governments have planned or conducted field experiments in order to estimate the causal effects of basic income. This study explores the Finnish and Dutch basic income experiments in methodological perspective. All the World have been watching the experiments in these two countries with keen interest. The results of these experiments will surely influence on the pros and cons of basic income in numerous countries, including South Korea. It is important to precisely figure out the methodological meanings and limitations of the experiments, for the experiments in both countries deal with only some partial components of basic income and have been exposed to many threats to internal validity. Therefore, scholars for and against basic income should be careful in interpreting the findings from these experiments. This study elucidate the methodological meanings and limitations of the Finnish and Dutch basic income experiments. Furthermore, this study extracts some lessons from these experiments that would be useful if scholars would have an opportunity to design and conduct a basic income experiment in South Korea.

  • In this study, aesthetic impressions were used for a high-level feature of image retrieval. The term, 'aesthetic' has been studied in psychology, art, and literature. It means unconscious, instantaneous parts of visual perception and emotion. The literatures related to aesthetic impressions were reviewed and four kinds of aesthetic impressions were defined operationally : strong impression, soft impression, courteous impression, and refined impression. 66 image files of paintings were sampled randomly from 1100 paintings and low-level color features were extracted from them by a using perceptual color model(Lai, & Tait, 1998). The high-level features of an image, that is, four kinds of aesthetic impressions of each painting were measured by 4 subjects and averaged. In CBIR, 2 subjects performed image retrievals using example queries. They were asked to retrieve images by using the aesthetic impressions or the keywords. In evaluations, subjects showed that they were satisfied with the aesthetic impression-based image retrieval system on the average. And R-precision of the image retrieval with both color features and aesthetic impressions was higher than that of the image retrieval with color features only. But further studies with larger test collections and query sets should be followed for generalization of the result of this study.

  • This study repeated low-frequency transcranial magnetic stimulation (rTMS) to evaluate the effects on cognitive function in chronic stroke patients. Among the chronic stroke patients, 30 patients selected by MMSE-K and BCRS-K were divided randomly into 3 groups. Group I (n=10) had only sound applied, group II (n=10) were applied 1 Hz rTMS on the damaged side and group III (n=10) were applied to 1 Hz rTMS on the opposite side for total 2 weeks, 20 minutes per a day, five times per a week. To examine the change in cognitive function, CREAD-K scores were measured before, 1 week, 2 weeks, and then 3 months after the intervention. The CREAD-K scores were measured before and 1 week, 2 weeks and 3 months after the interventions. The immediate recall memory showed a significant difference after 2 weeks and 3 months in groups II and III (p<.05), The recognition memory showed a significant difference after 2 weeks and 3 months in group III (p<.05). The delayed recall memory showed significant differences after 3 months in group III than in group I (p<.05). Therefore, the application of low-frequency rTMS has a positive influence on the cognitive rehabilitation of chronic stroke patients.
