  • PURPOSE: The purpose of this study was to provide clinical basic data to reduce pain and improve function by comparing neck muscle activity and neck alignment using self-stretching and passive stretching exercises for chronic neck pain caused by forward head posture. METHODS: The subjects were divided into 15 subjects assigned to perform self-stretching exercise and 15 subjects assigned to perform passive stretching exercise. The intervention was conducted for a total of 4 weeks. The muscle activity in the neck was measured by surface electromyography (EMG) before intervention, and craniovertebral and cranial rotation angles were measured by X-ray. The 4-week intervention was conducted and the above items re-measured in the same manner and analyzed. RESULTS: Muscle activity within both groups after intervention using self-stretching or passive stretching exercise was significantly different (p < .05)(p < .01). Neck alignment of both groups was significantly different (p < .001)(p < .01). Further, muscle activities of the upper trapezius and splenius capitis muscles showed significant differences (p<.05). Lastly, neck alignment showed statistically significant difference (p < .05). CONCLUSION: Self-stretching exercise activated motor nerves as a posture correction exercise, thereby improving inhibition of muscle activity, muscle contraction delay, and pathological conditions of the muscle. For future research, interventions of self-stretching exercise will be needed for patients with chronic back pain accompanied by forward head posture, and various clinical studies on postural improvement of forward head posture by maintaining a normal muscle tone state are needed.

  • As an application of big data and artificial intelligence techniques, this study proposes an atypical language-based sentimental opinion poll methodology, unlike conventional opinion poll methodology. An alternative method for the sentimental classification model based on existing statistical analysis was to collect real-time Twitter data related to parliamentary elections and perform empirical analyses on the Polarity and Intensity of public opinion using attribute-based sensitivity analysis. In order to classify the polarity of words used on individual SNS, the polarity of the new Twitter data was estimated using the learned Lasso and Ridge regression models while extracting independent variables that greatly affect the polarity variables. A social network analysis of the relationships of people with friends on SNS suggested a way to identify peer group sensitivity. Based on what voters expressed on social media, political opinion sensitivity analysis was used to predict party approval rating and measure the accuracy of the predictive model polarity analysis, confirming the applicability of the sensitivity analysis methodology in the political field.

  • Background: This study aimed to investigate the effects of noninvasive electrical stimulation combined with trunk stabilization exercise on balance and fall risk in patients with stroke. Methods: Twenty-two patients with stroke were enrolled in the study and randomly divided into experimental and control groups, each with 11 patients. noninvasive electrical stimulation combined with trunk stabilization training was applied to the experimental group, and sham noninvasive electrical stimulation combined with trunk stabilization training, to the control group. Both groups were treated for 6 weeks, five times a week for 30 min each time; the balance and fall risk of patients with stroke were measured before and after treatment, and the changes in the two groups were compared and analyzed. Results: The experimental group's left and right weight-bearing indices (affect and non-affect sides) and the front and rear weight-bearing indices, were significantly improved (p<.05, p<.001). when the changes in balance ability between groups were compared before and after treatment. The total fall efficacy score in the experimental group was substantially lower than that in the control group when the changes in fall efficacy score were compared between groups following treatment (p<.001). Conclusion: The improvement in balance and fall risk in patients with stroke can be attributed to using noninvasive electrical stimulation in combination with trunk stabilization training. This clinically helpful treatment method for patients with stroke warrants further promotion and implementation in the clinic.

  • Purpose : The goal of this study is to examine the effect of robot assisted gait training (RAGT) on the kinematic factors (temporospatial gait parameters, gait cycle ratio, and gait line length) of gait in stroke patients. Methods : The subjects of this study were 24 stroke patients selected by inclusion criteria. Participants were randomly allocated to two groups: robot assisted gait training (n=11) and general neurological physical therapy group (n=11). In the robot-assisted gait training group, robot-assisted gait training was mediated for 30 minutes a day in addition to general neurological physical therapy. The general neurological physical therapy group was mediated by general neurological physical therapy for 30 minutes a day in addition to general neurological physical therapy. The number of interventions was 5 times a week for 5 weeks. In order to compare the kinematic factors of walking between the two groups, gait analysis was performed before and after 5 weeks of training using the Zebris gait analysis system. Results : As a result of the gait analysis of the two groups, there were significant differences in temporospatial gait variables (step length, stride length, step width, step time, stride time), gait cycle ratio (swing phase, stance phase) and gait line length. However, there was no significant difference in the cadence (temporospatial gait parameters) in the robot assisted gait training group compared to general neurological physical therapy group. Conclusion : It is considered to be a useful treatment for stroke patients to promote the recovery of gait function in stroke patients. Based on the results of this study, continuous robot assisted gait training treatment is considered to have a positive effect on gait ability, the goal of stroke rehabilitation. In the future, additional studies should be conducted on many subjects of stroke patients, the kinematic factors of the legs according to the severity of stroke and treatment period, and the effect of gait training.

  • As the public Japanese art, print can be said to have started from Ukiyo-e print of Edo period(江戶時代, 1603~1867). Ukiyo-e(浮世繪) print, which 3 persons jointly produce, henceforth has gradually declined since the meiji period(明治時代, 1868~1912) due to the development of new print technique and introduction of western art. Since then, during the daiso period(大正時代 1912~1926), creative print movement grew up. Creative print is, differently from Ukiyo-e print, to be produced by one person, from the original picture to print, focusing on creating the artist's own work by being the main agent of the work. During before and after 1900s, print was evaluated low in Japan, compared to western painting, sculpture, etc. Nevertheless, the facts that several Japanese print artists received awards from international exhibits since 1950s became a big topic internationally, which became an opportunity to hold Tokyo International Print Biennale in 1957 in Japan, the first international art festival. From then on, print was recognized as an art genre while new recognition on it was gradually accepted also in Japan. In 1970, a controversy on it arose, while the characteristic of print as a medium of modern art became strong, accordingly, a controversy on it arose. However, in 1980, it firmly established itself as an art genre by overcoming the crisis through various efforts in the dimension of print artists and university education. Since then, print artists who produce new works with completeness by applying traditional technique and modern expression mode emerged, and until now Japanese modern print art is highly recognized by the world through the continuous overseas activities, research on print art, and cultivation of young print artists. This research looked back on the historical process when Japanese modern print art was created, which represents Asia, and investigated the cause that it could have win an international fame.
