Restless Legs Syndrome/Willis-Ekbom Disease (RLS/WED) is a sleep disorder characterized by sensorimotor symptoms such as unpleasant sensations before sleep, akathisia, and periodic limb movements during sleep. It is also closely related to hyperarousal and is often accompanied by insomnia. Although the mechanism is not clear, the understanding of etiology and pathophysiology has greatly expanded through recent advances in genetic and neurobiological research. The most important pathophysiology of RLS/WED is brain iron deficiency. Such iron deficiency in the brain is caused by complex interactions between several genetic factors and various environmental factors, including comorbidities. Iron deficiency in the brain results in dysfunction of several neurotransmitters. A decrease in adenosine activity appears first, followed by an increase in the activity of glutamate and dopamine. A decrease in adenosine activity and an increase in glutamate activity stimulate the brain arousal system, resulting in hyperarousal. In addition, overproduction of dopamine and glutamate leads to dysfunction of the cortical-striatal-thalamic circuit, resulting in symptoms such as akathisia and periodic limb movements during sleep.

Objectives : The purpose of this study was to assess the effect auricular acupuncture for acute mental stress using power spectrum analysis of the heart rate variability(HRV). Methods : 10 healthy volunteers participated in this study. After 5 minute rest, the first mental stress was provided for 5 minute. And then subjects rested for 15 minute. The second mental stress was provided for 5 minute. The acupoint, Shin-Mun point of the ear was stimulated for 15 minute. HRV was recorded before and after the first and second mental stress, and after auricular acupuncture stimulation. Results : After mental stress, normalized LF and LF/HF ratio is significantly increased. Before and after simple rest, normalized LF and normalized HF is significantly changed, but LF and LF/HF ratio is not significantly changed. On the other hand, before and after auricular acupuncture treatment, normalized LF, normalized HF is significantly changed, and also LF and LF/HF ratio is significantly decreased. Conclusion : The result suggest that auricular acupuncture can decrease more significantly in cardiac sympathetic activity due to mental stress than simple rest.

Purpose: The purpose of study was to examine the relationship between obesity and its associated factors (psychiatric symptom, duration of illness, type of medication, physical activity, dietary habits, depressive symptom, and stress) in patients with chronic mental illness registered to community mental health welfare centers. Methods: This was a cross-sectional correlation study using a convenience sampling. A total of 392 participants were recruited from community mental health welfare centers. The obtained data were analyzed using binary and multinomial logistic regression. Results: Atypical antipsychotic medication, duration of illness, dietary habits (overeating, and drinking instant coffee) were significantly contributed variables into body mass index (BMI) obesity. Atypical antipsychotic medication and instant coffee were significantly related to abdominal obesity. Conclusion: These results emphasized the needs of tailored obesity-preventive management for the community-dwelling patients with chronic mental illness, topically focusing on the administration of atypical antipsychotic medication, duration of illness, and dietary habits.

Purpose: The purpose of this study was to identify the relationships between physical activity, health status, and quality of life (QOL) of University students. Methods: The research design was based on a descriptive research design model. This study sample consisted of 183 K University students in D city. Data was collected from December 2012 to January 2013 and analyzed with descriptive statistics (frequency, percentage, analysis of variance (ANOVA), t-test, and Pearson's correlation analysis) using SPSS 19.0. Subjects completed questionnaires on their demographics, physical activity, health status, and QOL. Results: The overall physical activity of participants was $2529.40{\pm}5057.896$ min/week on average. The average health status was $28.66{\pm}6.3$ and the average physical health and mental health were $16.45{\pm}3.955$ and $12.31{\pm}3.446$, respectively. The overall degree of QOL was $3.429{\pm}0.379$. A positive relationship existed between moderate and vigorous activity and health status. In addition, QOL positively correlated with physical health (under health status). However, physical activity was not related with both mental health (under health status) and QOL. Conclusion: Based on the results of this study, health educational programs are needed to promote sufficient physical activity in university students.

Background: Bus driving is a mentally demanding activity that requires prolonged attention to ensure safety. The aim of the study was to assess mental fatigue caused by driving a public bus and to find a profile of workers at higher risk. Methods: We evaluated changes of critical flicker fusion (CFF) (index of central arousal) and heart rate variability (HRV) (index of autonomic balance) in a 6-hour driving shift on a real route, in 31 professional bus drivers, and we tested the influence of personal factors such as sleep quality, BMI, and age. Paired t-test was used to test differences of CFF and HRV between both initial and final phase of driving, while multiple linear regression tested the influence of personal variables on the indexes of mental fatigue. Results: Results showed that CFF significantly decreased after 6 hours of bus driving (41.91 Hz, sd 3.31 vs. 41.15 Hz, sd 3.15; p = 0.041), and heart rate significantly decreased in the final phase of driving, with respect to the initial phase (85 vs. 78 bpm, p = 0.027). Increasing age (beta = -0.729, p = 0.022), risk of obstructive sleep apnea syndrome (beta = -0.530, p = 0.04), and diurnal sleepiness (beta = -0.406, p = 0.017) showed a significant effect on influencing mental fatigue. Conclusion: Elderly drivers at higher risk of sleep disorders are more prone to mental fatigue, when exposed to driving activity. Monitoring indexes of central arousal and autonomic balance, coupled with the use of structured questionnaires can represent a useful strategy to detect profile of workers at higher risk of mental fatigue in such duty.

This study is purposed to suggest the method for improving the effect of the mental health project by checking the influence of the "value and function of the mentally disabled" to the "satisfaction to current life of the mentally disabled" for the users of the daytime mental rehabilitation service in the local community, and the difference in the"satisfaction to the current life of the mentally disabled" and "value and function of the mentally disabled" depending on the participation into the mental rehabilitation program. With regard to the "satisfaction to the current life of the mentally disabled", the result showed that the "relation between the current user members" and "consideration about himself in usual time" were the positive influential factors out of the measuring factors for the "value and function of the mentally disabled." In addition, with regard to the "satisfaction to the current life of the mentally disabled", in case of participating to the "vocational rehabilitation program" out of the mental rehabilitation programs, the general "personal value and function which are felt by the mentally disabled" has higher significant difference in case of participating into the "social technology program", "daily life program", "vocational rehabilitation program", "leisure activity program" out of the mental rehabilitation programs than non participating.

Through the discussions on ascending, descending, in and out of functional activity of Ki, Nature and Life(性命) based on the correlations among essence of life, Ki and vitality, and the Heart which is the complex of heart and place of mental activity, orientation of 'Life(生命)' in "Dongeuibogam" is that heart and body are in a single construction not in two. Although "Dongeuibogam" has the characteristics of substantial discussions about prevalent inner Dan thought in those days in the medical field, it is quoted in the aspect of guiding and leading the Nature and Life(性命). As the nature of heart was developed psycological and physically, we could sense the influences of Confucian-medicine that accounted the Heart which is the place of mental activity and the Sung Confucianism trend of Chosun dynasty.
