  • Purpose : The purpose of this study was to investigate the effects of stabilization exercise and breathing exercise on the flexion relaxation phenomenon (FRP) and respiratory parameters in patients with chronic low back pain. Methods : We randomly allocated 30 chronic low back pain patients (CLBP) to a stabilization exercise (SE) group (n=15) and a breathing exercise (BE) group (n=15). FRP was measured using surface electromyography (SEMG). Thoracic excursion was measured with a cloth tape measurement technique. The SE group participated in a stabilization exercise program and the BE group participated in a breathing exercise program three times a week for 12 weeks. The data was analyzed using paired t-tests for comparisons of flexion relaxation ratio (FRR) and respiratory variables. Independent t-tests were used for comparison of inter-group FRR and respiratory variables. The significance level was set at .05. Results : FRP variables-ES FRR (Flex/MVF), ES FRR (Ext/MVF), MF FRR (Flex/MVF), and MF FRR (Ext/MVF) values-increased significantly after exercise in both the SE and BE groups (p<.05). The thoracic excursion measurements after exercise increased significantly in both groups (p<.001). VAS values decreased significantly in both groups (p<.001). There were no significant differences between the two groups in FRP variables-ES FRR (Flex/MVF), ES FRR (Ext/MVF), MF FRR (Flex/MVF), and MF FRR (Ext/MVF)-or VAS values after exercise (p>.05). For thoracic excursion after exercise, the BE group was significantly higher than the SE group (p<.001). Conclusion : We found that FRP and respiratory variables increased significantly after SE and BE for 12 weeks in CLBP. Thoracic excursion-a respiratory variable-suggests that treatment was more effective in the BE group than the SE group.

  • Purpose : The purpose of this study was to examine the correlation between static and dynamic balance according to the virtual reality-based squat and conventional squat exercise. Methods : Twenty four participants were randomly assigned to the virtual reality-based squat (VRS) group (n=12) or conventional squat (CS) group (n=12). The static balance (C90 area, C90 angle, trace length, sway average velocity) and dynamic balance (forward, rearward, leftward, rightward) were measured using a force plate by BT4. The VRS group used the virtual reality system during 4 weeks, while the CS group underwent classical squat training. Independent t-test was used to test the homogeneity of the general characteristics of the subjects. The collected data was analyzed using the paired t-test for static and dynamic balance comparisons before and after exercise in both groups and Pearson's test for the correlation between static and dynamic balance according to the measured time. The significance level was set to 0.05. Results : There was no significant correlation between group and static and dynamic balance related variables (p>.05). There was a significant correlation between measurement time and static and dynamic balance related variables (p<.05). According to the measurement time, the static balance parameter C90 area in the VRS group after exercise was significantly decreased (p<.05). The values of forward, leftward and rightward in the VRS group were significantly increased after exercise (p<.05). Conclusion : It is suggested that 20 normal healthy adult men and women who have normal balance ability can improve their ability to control their posture by improving the balance ability when applying virtual reality-based squat exercise.

  • PURPOSE. The purpose of this study is to investigate the effects of aging and various risk factors on the oral environment and to analyze them in 3-dimensions. MATERIALS AND METHODS. A total of 800 patients were enrolled in this study, and subjects were divided into 4 groups by age-under 55, 56 - 65, 66 - 75, and over 76. Based on their most recent visit, the number of crowns, bridges, implants, and the remaining natural teeth were recorded. Smoking habits, along with presence of diabetes and hypertension, were surveyed, as risk factors were also set as a variable. Comparisons among the groups or within the groups were performed by independent t-test, and one-way and two-way ANOVA. Kruskal-Wallis test and Mann-Whitney U test were used for analysis. It was assumed to be statistically significant when P value is below .05. RESULTS. Changes in the number of crowns, bridges, implants, and the remaining natural teeth by age were statistically significant. When we examined the effect of risk factors on the change of variables with age, hypertension was found to affect the number of bridges. Diabetes and smoking were found to affect the number of the remaining natural teeth. The other variables were not statistically significant. CONCLUSION. Aging is considered to be an important variable affecting the change of oral environment. Among the risk factors, the presence of smoking habit and diabetes is thought to have a great influence on the change of the number of the remaining natural teeth.

  • This study analyzes the effect of the level of satisfaction with the living environment of rural people on migration. The analysis data were used by the Rural Development Administration for the survey of welfare systems for farmers and fishermen in 2017, and samples of 3,776 were used for the analysis. The analysis variables were divided into a group of migrants, a group of permanent residents, and a group of decision-keeping, and the level of satisfaction with the living environment of each of the 10 rural areas was used as an independent variable. According to the analysis results, the basic living base and safety of rural residents were having a positive effect. The results show that the projects for developing rural areas, which increase the basic living base, are making substantial contributions to preventing the breakaway of the rural population. Safety has been neglected in the area of rural planning, but if the level of discontent is not enough, it has had the greatest impact on the livelihoods of rural residents. Welfare and cultural leisure set the main demand level for welfare and cultural leisure to the elderly and vulnerable classes, and interpret it as a result of weakened defense against stress from relocation of residence, difficulty of migration due to low income levels, and migration. Therefore, the paradoxical analysis results could be interpreted as showing that measures to increase the satisfaction of the people on welfare and cultural leisure should be taken.

  • In modern society, efforts to improve quality of life and happiness are emphasized compared to the past when economic growth was emphasized. The government has been implementing various policies to realize the happiness of the people through culture. The purpose of this study is to investigate the effect of Cultural Arts on the improvement of the happiness index of Seoul citizens by dividing them into demand (enjoyment) and supply side by setting Cultural Arts as independent variable, unlike existing limited surveys or literature surveys, under the control of change, the temporal range was set for more than 10 years and then analyzed quantitatively by panel analysis. The results showed that the demand for cultural arts affects positively on the improvement of happiness index of Seoul citizens, but the supply of cultural arts had a meaningless effect. In order to improve the happiness index of the citizens of Seoul through supply, it is necessary to supplement the existing space and to promote cultural demand through differentiated cultural arts programs aimed at diverse classes but also the policy implication that cultural indifference groups and active participation of cultural underprivileged groups should be increased.

  • Green belts can help to set boundary for city growth, provide ecological protection system and enhance the resilience of Beijing. During the implementation period of the current overall city planning of Beijing, the proportion of green space varies much among the sub-districts, villages and towns involved in the two green belts in the research. With this as starting point, by researching the correlations of 'city system factors' and 'planning policy factors' with the change in the scale of green space, the paper discussed the influential factors of implementing the planning of green space of Beijing, and conducted quantitative research, with such possible influential factors classified into 'city system factors' and 'planning policy factors'. Through multiple linear regression model, the paper tested the correlations of city system factors and planning policy factors (independent variable) with the increment in the construction land in green belts (dependent variable). Through influence to population aggregation and the expansion force of construction land, city system factors such as mountain land and water, house rent of unit area, accessibility of public transport and the newly-defined state-owned construction land generate correlation with the change in the scale of construction land in green belts.

  • PURPOSE: This study examined the effects of the chopping pattern of proprioceptive neuromuscular facilitation (PNF) on the neglect, balance ability, and activities of daily living in stroke patients with hemi-spatial neglect. METHODS: Twenty stroke patients with neglect volunteered for this study. The subjects were assigned randomly to either the experimental group (EG, n=10) or control group (CG, n=10). The chopping pattern of PNF and exercise therapy were applied in the EG and CG, respectively, for four weeks. Neglect, balance, and activities of daily living were evaluated at the pre-and post-intervention. The assessment tools included a line-bisection test, balance test using Space balance 3D, and modified Barthel index. The pre-and post-intervention values were compared in each group using a paired t-test and the between-group differences were assessed using an independent t-test. Statistical significance was set to ${\alpha}=.05$ for all variables. RESULTS: Significant differences were observed between the EG and CG in terms of neglect, balance, and activities of daily living (p<.05). Both groups showed significant improvement in neglect, balance, and activities of daily living (p<.05). CONCLUSION: These results suggest that the chopping pattern of PNF is effective in improving the hemi-spatial neglect, balance, and activities of daily living in stroke patients with neglect.

  • The use of food grade hexane (FGH) for edible oil extraction is responsible for the presence of benzene in the crude oil. Benzene is a Group 1 carcinogen and could pose a serious threat to the health of consumer. However, its detection still depends on classical methods using chromatography which requires a rapid non-destructive detection method. Hence, the aim of this study was to investigate the feasibility of using Fourier transform infrared (FTIR) spectroscopy combined with multivariate analysis to detect and quantify the benzene residue in edible oil (sesame and cottonseed oil). Oil samples were adulterated with varying quantities of benzene, and their FTIR spectra were acquired with an attenuated total reflectance (ATR) method. Optimal variables for a partial least-squares regression (PLSR) model were selected using the variable importance in projection (VIP) and the selectivity ratio (SR) methods. The developed PLS models with whole variables and the VIP- and SR-selected variables were validated against an independent data set which resulted in $R^2$ values of 0.95, 0.96, and 0.95 and standard error of prediction (SEP) values of 38.5, 33.7, and 41.7 mg/L, respectively. The proposed technique of FTIR combined with multivariate analysis and variable selection methods can detect benzene residuals in edible oils with the advantages of being fast and simple and thus, can replace the conventional methods used for the same purpose.
