The purpose of this study was to investigate the differences of lumbar muscle activity (LMA) and oxygen consumption (OC) according to bike saddle height in healthy young men. Twenty-two subjects without musculoskeletal disorders participated in this study. Subjects performed 3 min cycling at 3 different saddle heights with 10 minutes of resting time respectively. Surface EMG was used to assess muscle activity in LMA, and OC was assessed by potable gas analyzer. In the result, there was a statistically significant difference in internal oblique abdominis activity (p<0.05), and the OC was significantly higher in high saddle height than the optimal and the low position of the saddle (p<0.05). This study suggest that changes in saddle height affected internal oblique abdominis activity and OC in subjects, however, saddle height does not have much effect on lumbar stabilizer muscle.

This study aims to examine the effects of employment on the physical health, psychological function, and life satisfaction of the elderly. Participants were 4,165 persons (men 1,739, women 2,426) aged 65 over. Physical health was composed of ADLs(Activities of daily living), pains, and disorders. Psychological function was measured by cognitive functions (subtraction, instruction execution, memory test, and item use) and emotional difficulty. Life satisfaction, work satisfaction, and work level were also measured. Major findings in this study are as follows: First, gender, marriage, and education level had significant effects on the participants' life satisfaction, but religion and financial incomes did not. Second, employment had significant effects on their physical health, psychological function, and life satisfaction. Third, pain, cognitive functions, emotional difficulty, and work satisfaction had significant effects on the life satisfaction of the working elderly. But, work level and incomes had not significant effects on the elderly's life satisfaction. In addition, an interaction between cognitive functions and emotional difficulty on life satisfaction was found.

This study examined the prevalence of an impaired fasting glucose and related factors in normal non-diabetic adults. This study used the raw data (general characteristics, health behavior, obesity, impaired fasting glucose etc.) from the 6th Korea National Health & Nutrition Examination Survey (NHANES) in the second year (2014), and out of all 7,550 survey participants, 1,341 were selected as the final research subjects. After stratifying according to obesity, a logistic regression model was used to analyze the factors related to an impaired fasting glucose level. The older subjects were more likely to have an impaired fasting glucose in both the obesity group and normal weight group (p<.001). The obesity group showed a higher impaired fasting glucose rate when they drank more alcohol (p<.05) and consumed less fruit (p<.05). Therefore, balanced nutrients and control of the blood sugar level through proper education and public health policies of fruit intake and alcohol are needed.

The purpose of this study was to identify the characteristics of health-related indicators according to the participation of swimming program by adults with intellectual disabilities(ID). To this end, 20 adults with IDs, aged 20-39 living in Busna, were selected. Participants divided into two groups: swimming program participation(n=10) and non-participation(n=10). Data were collected by measuring the subjects health-related physical fitness, stress hormones, and immune function and data analysis was conducted using SPSS 18.0, paired t-test, independent t-test and two-way ANOVA. As a result, muscle strength(p<.001), muscular endurance(p<.001), flexibility(p<.001), cardiovascular endurance(p<.01) improvement of exercise group significantly but there was no significant difference in the control group. The stress hormone cortisol(p<.01) was significantly decreased in the exercise group and there was no significant difference in the control group. The immunoglobulins, IgA(p<.05), IgG(p<.001), IgM(p<.05) were significantly increased in the exercise group, but not significantly different in the control group. Therefore, regular swimming program can be said to be a very effective exercise program for improving the physical fitness of adults with IDs, and it is thought that it can reduce stress and help improve immune function. This suggests the need for active physical activity program development and intervention to maintain the health of adults with IDs and prevent chronic diseases.

This study was undertaken to determine the effects of SNAGs (sustained natural apophyseal glides) and visual convergence biofeedback on the proprioception and neck disability of patients with chronic neck dysfunction. A total of 31 patients with neck dysfunction were assigned to either SNAGs (n = 16) or biofeedback (n = 15). The groups were assessed for proprioception and neck disability, before and after the intervention. The SNAGs were performed using belt with flexion, extension and right-left rotation, whereas biofeedback training included visual feedback training with deep neck flexor. Intervention was implemented for 20 minutes, twice a week for 4 weeks. Biofeedback training a showed significant effect on the joint position sense (left and right rotation) as compared to the SNAGs group (p< 0.05), whereas neck disability index was significantly effective for SNAGs (p< 0.05). Ed. Notes: The previous statement lacked clarity. I have suggested the edit as per my understanding. Please review and revise appropriately, if required. Therefore, the SNAGs technique is effective for neck function, and biofeedback training is a positive intervention method for enhancing the proprioceptive sensation. In future studies on patients with neck pain, it may be possible to select an intervention method based on the characteristics of the disease.

The self-employment can provide work time flexibility. Work time flexibility would be a critical factor for married females' labor supply considering allocation of their time to market work and household work. This study used the 1998 and 2000 Korea Labor and Income Panel Survey for the empirical analyses. Applying the bivariate probit model with partial observability, this study analyzed factors related to the choice of participation in labor market and choice of self-employment. Also, this study examined the effects of marriage and the presence of younger children on changes in decisions related to labor supply using the multinomial logit model: exit from the labor market, increasing and decreasing work hours. The presence of the younger children showed a significantly negative effect on the participation in labor market while positive, but insignificant, effect on self-employment. Compared with females working for others, self-employers without employees and unpaid family workers are less likely to exit labor market rather than increasing work hours. The self-employment would be a good alternative to evade females' career interruption and therefore to enhance the potential human resources.

Botulinum toxin injection has been used in the masticatory muscle area as an effective treatment method of various movement disorders and facial contouring, but its effects on jaw function have not been evaluated. The aims of this study were to evaluate the effects of botulinum toxin type A injection into the masseter muscle on the EMG activities of masseter and anterior temporal muscles, and the limitation of jaw function. Fourteen healthy subjects were recruited. Five subjects were injected with 80 units of botulinum toxin type A(Dysport, Ipsen, Wrexham, UK) into each side of masseter muscle, and nine subjects were injected with saline into the same site as the botulinum toxin group. The surface EMG activities at maximum voluntary contraction of masseter and anterior temporal muscles were recorded before, 1 week, 2 weeks, and 3 weeks after injection. Presence of jaw functional limitations in each subject was investigated using Korean version of Jaw Functional Limitation Scale(JFLS) questionnaire. The masseter muscle EMG was gradually decreased in the botulinum toxin group comparing with that of the control group(p<0.001), but the anterior temporal muscle EMG did not show significant changes. There was significant increases in the mastication (p<0.01), and global jaw limitation(p<0.05) subscales of JFLS at 1 week after injection, but no significant changes in the other subscales including opening, and verbal and emotional expression during the recording periods. Our results suggest that botulinum toxin injection into masseter muscle can affect modest limitation in mastication function at 1 week after injection but recovered to the baseline until 3 weeks after injection. The EMG activity of masseter muscle had been gradually decreased until 3 weeks after botulinum toxin injection but the anterior temporal muscle did not show any significant changes.
