The purpose of this study is to verify the effects of yoga and meditation-focused forest healing programs on profiles of mood states and stress reactions of adults. We tested 17 adults who agreed to participate in the experiments that were conducted for 2 nights and 3 days between September 8 to 10, 2017 in the healing forest located at Hongcheon-gun, Gangwon-do. The test used the simplified version of the inventory for the profile of mood states (K-POMS-B: Korean version of Profile of Mood States-Brief) and the stress response inventory as the measuring tools. For data analysis, we examined the differences in the profile of mood states and stress response of subjects before and after participation in the program through the paired T-tests with the SPSS 24.0 program. The analysis of the impact of the yoga and meditation-focused forest healing program on the profile of mood states of the test subjects showed the statistically significant reduction of the total score of the profile of mood states. Although the vigor among sub-level inventories increased, it was not statistically significant. But the tension, depression, anger, fatigue, and confusion showed a statistically significant reduction. The analysis of the impact of the yoga and meditation-focused forest healing program on the stress response of the test subjects showed a statistically significant reduction. Among sub-level inventories, the tension, somatization, anger, depression, fatigue, and frustration showed a statistically significant reduction, but the aggressiveness did not. It is expected that the results of this study can be utilized in the future as reference data for clarifying the effects of yoga and meditation-focused forest healing programs.

Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in person's mood, energy, and ability to function. Compared with manic episode, the depression episode causes more serious results such as restless, loss of interest or pleasure, or thoughts of death or suicide and the cure rate of depression episode is lower than that of manic episode. Furthermore, a long term use of antidepressants in bipolar patients may result in manic episode. Our interest is to investigate the effect of antidepressant on switch of moods of bipolar patients and to estimate the transition probabilities of switch between moods, depression and (hypo) manic. In this study, three approaches are applied in terms of multi state model. Parametric model is applied using left censoring data and nonparametric model is implemented under illness-death model with counting process. In order to estimate the effect of covariates, a multiplicative model is used. These all methods have similar results.

This study compared the effect of different types of sounds(no sounds, sounds of nature, music, and sounds of children playing) on profile of mood states(POMS) in a healing forest. Data were collected from 231 respondents selected from among visitors to the 'Healing Field' in 'Jangseong Chukryongsan Pyeonbaek Healing Forest' in October, 2012. Each respondent was exposed to one type of sound. The results showed that there were differences in POMS among the different sound treatment groups. Sounds of children playing showed negative effects on POMS. Unexpectedly, however, sounds of nature and musical sounds had no effects on POMS. These tendencies were consistently found not only for total mood disturbance score (TMDS) but also for POMS by factors (i. e. tension, anger, vigor, fatigue, confusion, depression). Perceived crowding level was positively correlated with TMDS(r=0.568) and POMS by factors (range: r=0.331 - 0.571). This paper discusses the research results and suggests several managerial implications.

This study aimed to investigate the relationship between music listening and mood regulation. The effects of personality traits, music education, and sex on music use for mood regulation were also examined. Participants were 529 undergraduate students who completed the Korean Music in Mood Regulation Scale, Interpersonal Personality Item Pool (IPIP), Positive Affect and Negative Affect Schedule, and a questionnaire on their music education. Correlation analysis, multiple regression analysis, and t tests were conducted to explore the relationship among the measured variables. The results showed that music listening was related to enhancement of positive mood but not improvement of negative mood. Participants who had received extracurricular music education were more likely to use music listening as a strategy to regulate their mood than were participants without music education. Women were more likely to use music for mood regulation than were men. The multiple regression results indicate that individuals who rated themselves highly on Agreeableness and Openness to Experience on the IPIP were more likely to listen to music for mood regulation. These findings stress that music listening can be an effective strategy for mood regulation, which is critical for one's emotional well-being. It also indicates that effective music use as a mood regulation strategy varies depending on one's personal characteristics and history of music education.

This study was conducted to investigate the effects of a forest therapy program on post-traumatic stress disorder (PTSD) and mood states of fire fighters. A total of 293 participants completed two psychological questionnaires before and after the program was conducted: the Post Traumatic Stress Disorder Checklist (PCL) and the Profile of Mood States (POMS). Data were analyzed with paired t-test and ANCOVA using SPSS 24.0. The PTSD results showed a significant decrease from 11.38 ± 12.58 points before the program to 6.91 ± 10.50 points after the program. Results of the POMS questionnaire revealed an increase in positive factors and a decrease in negative factors, with a significant overall decrease in POMS results from 8.58 ± 18.47 points before the program to -0.63 ± 15.83 points after the program. As a result of analyzing the differences in stress reduction effects according to the amount of sleep participants had, PTSD showed improvement at 6-8 hours of sleep. These results are expected to be utilized as a basis for stress management and relief in fire fighters.

This study was designed to investigate the relationships of depressed mood with obesity, blood and urinary compositions, and dietary habits in Koreans at the age of 40, a critical transition to the middle adulthood stage. A total of 27,684 people who have taken the Life Transition Period Health Examination at the Korea Association of Health Promotion in 2011 were divided into two groups; the depressed mood group (DG) and the non-depressed group (NG) according to results of the primary questionnaire for mental health. The results were analyzed using the health examination criteria of the National Health Insurance Corporation. Women and medicaid recipients showed higher incidence of depressed mood than men and health insurance subscribers. People with underweight in BMI or abdominal obesity showed correlation with depressed mood, while there was no significant relationship with metabolic syndrome. Regarding blood and urinary compositions, DG was related to a higher level of hemoglobin and lower levels of HDL-cholesterol and triglyceride, although the relationships diminished after adjustment for other confounder effects. According to dietary habits, more people in DG were categorized as a group for "Needs Much Improvement", and the odds ratio of the depressed mood showed a significant increase. Significant difference regarding the frequency of food items such as milk products, animal proteins, Kimchi, and fruits was observed between DG and NG. In addition, a higher portion of subjects in DG did not consume regular meals and various kinds of food. In conclusion, the depressed mood of 40 year-old adults was significantly related to underweight, higher waist measurement, and undesirable dietary habits. Results of our study can be applicable as a basic resource for development of effective nutrition counseling and education programs for improvement of mental health promotion during the critical transition to the middle adulthood stage.
