This study has investigated a psychological status of optimal and pleasant driving condition by measuring various physiological signals using SCR(skin conductance response), PPG(peripheral plethysmograph), SKT(skin temperature) and HR(heart rate). The physiological response was measured during various simulated driving conditions. We developed a hardware and algorithm to measure and analyze the physiological response. The physiological signals has reflected the level of driver's tension or relaxation as well as the heart rate. The emotional responses of drivers were also measured and analyzed in this experiment. The result of the study can be used to design a system to enhance the driver's emotional satisfaction as well as to monitor the driver's safety and health condition.

This study examined changes of both psychological and physiological emotional responses according to change of the PMV (predicted mean vote) in the heating and the cooling air conditions. For this purpose, the changes of PMV were induced by the heating and cooling operations of the HVAC (heating, ventilation, and air conditioning) systems. In addition, positive/negative and arousal/relaxation were measured as the participant's psychological emotional responses, and HR (heart rate) was measured as the participant's physiological emotional responses. As a result, in same range of the PMV, both psychological and physiological emotional-responses were changed by air conditioning. It is suggested that occupant's emotional responses would depend on the operational conditions of heating and cooling in indoor thermal environments, and both psychological and physiological emotional response should be considered when occupants try to match the indoor thermal environments to their thermal expectations.

This study was conducted to find out the psychological or physiological healing effects of real natural forests and virtual forest experiences using virtual reality (VR) in an artificially-controlled digital environment. To find out this, 81 healthy undergraduate students from C University were experimented on visual forest stimulation effects in the digital environment from September 5 to December 9 in 2022. The experiment evaluated the psychological and physiological healing effects of visual forest stimulation in the digital forest environment (2D, 3D). The SRI (stress response inventory) experiment for analyzing psychological effect showed statistically significant differences among groups. As for the SRI experiment for measuring psychological stress, except Control group, 2D group in the digital environment showed little difference before and after the experiment. But 3D group showed less stress than before. As a result, it was proved that visual forest stimulation in a forest-based digital environment (2D, 3D) reduces psychological stress significantly. And when analyzing how visual forest stimulation changes EEG (electroencephalogram) in the digital environment, alpha waves (RA), which are activated during relaxation or stabilization, were more active than beta waves (RB), which are activated during tension or awakening. This study is expected to be used to create a psychological and physiological healing environment for those who cannot go to a natural forest due to mobility difficulties by providing them visual forest stimulation experiences in a digital environment. It is also expected that the results will be the basis for forest healing in the digital environment and virtual reality programs will help forest healing activities.

Massage therapy is a traditional, alternative and nonphamacological means of promoting rest and relaxation. However, nursing intervention by massage for middle-aged women is rarely practiced by nurses. The purpose of this research was to examine the effects of the hand and arm massage as an independent nursing intervention tool for middle- aged women. The data used in this research were collected from forty-nine subjects using a nonequivalent control group non- synchronized design. Twenty-four persons for the experimental group and Twenty-five persons for the control group were selected from D city and C city from July 1997 to September 2000. Subjects' ages were between forty and fifty-six years old with mean the age of 45.6. Hand and arm massage developed by Cayce and Reilly was applied to the experimental group for a session of 15 minutes two or three times a week for four weeks. The instruments used for the measurement of the subjects' stress, anxiety, depression and the middle-life crisis were Langners's 22-item Self-rating Depression Scale, and Kim's Middle Life Crisis Scale(1988). These psychological factors were measured before and after the implementation of hand and arm massage. The data were analyzed with mean$\pm$s.d, percent, t-test, and a paired t-test. The results were summarized as follows; 1. Before the treatment, there were no significant differences between the two groups. 2. After the treatment, there were significant differences in the stress and the occurrence of mid life crisis between the two groups. The findings suggest that the use of the life crisis. Therefore, it is recommended that hand and arm massage be used as an independent nursing intervention tool for middle-aged women. For further research, is needed replication of this concept of research with different subjects in a larger population. Also, it is recommended to investigate the effects of massage with aroma therapy for the berefit of decreasing womens' stress level further.

Background and objective: In the Republic of Korea, military service is mandatory. Some of new recruits have the stress from the special environment, which could cause psychological maladjustment. The military forces have operated education programs such as green camp and healing camp. The study was conducted to investigate changes in psychological and physiological stress by conducting forest healing activities along with plant scent treatment for soldiers participating in a green camp. Methods: A total of 52 soldiers were participated including maladjustment soldiers and those recommended by their military units to protect the unfit soldiers who participated in forest healing activities in the green camp. The programs that were certified by the Korea Forest Service between 2014 and 2019, and were applied for stress reduction and relaxation training were classified into stress-coping programs and forest experience programs. Post-hoc surveys and cortisol measurements were carried out. Results: Green camp soldiers experience and differences in the level of stress responses were found to be very statistically significant between the treatment and control groups. The techniques for coping with stress were not significantly different in the control group, and the treatment group showed statistically significant results. In addition, the results of analyzing changes in the concentration of cortisol and measuring physiological stress were very statistically significant in forest healing activities at 4 p.m. Conclusion: Once green camp soldiers face stressful situations, forest healing programs using forest plant scents for green camp soldiers can have positive responses and forest healing activities can reduce psychological and physiological stress responses, improving maladjustment behaviors caused by stress and positively affecting the reduction of cortisol.

Background and objective: The elderly living in homeless living facilities for a long time suffer from various mental health problems. This study aims to determine the psychological, emotional, and social effects of a horticultural therapy program composed of gardening activities, which was designed based on the semantic structures of life for the homeless elderly living in the facilities for a long time. Methods: A total of 12 subjects (6 in the control group and 6 in the experimental group) participated in the study. The horticultural therapy program consisted mainly of gardening activities, and a total of 16 sessions were conducted once a week for 16 weeks, 60-90 minutes per session. The subjects were tested to evaluate their self-esteem, depression, and horticultural activities. The data were analyzed using the Mann-Whitney U test, Wilcoxon rank test, and Friedman test, which were nonparametric tests, conducted at a 95% significance level. Results: First, in the case of self-esteem, a significant difference was found between the groups, 20.00 points (SD = 5.69) in the control group, and 25.50 points (SD = 3.73) in the experimental group (p = .034). Second, in the case of depression, no statistically significant difference was found in the posttest. Finally, in the case of the horticultural activity evaluation, the scores of most variables gradually and significantly increased during the program [Verbal interaction during activity (p = .006), Self-concept and identity (p = .006), Need-drive adaptation (p < .001), Interpersonal and social relations (p < .001)]. Conclusion: These results support that the horticultural therapy program could help the elderly improve psychological relaxation, emotional stability, and social relationships. In order to generalize the results, it is suggested to increase the number of subjects or conduct additional repetitive experiments in further research.

Tension Myositis Syndrome is defined as the muscle syndromes affected by brain signal as a result of stress. Furthermore, painful muscles cause tensional emotions in body system. Pain is the result of mutual co-operations between the brain and muscles. Unpleasant feelings increase the pain intensity. In addition, painful muscles were seen to have influences on the brain neurological system. Therefore, in spite of physical treatments, chronic pain has a tendency to be persistent and incurable. For psychological cures, We applied deep breathing, muscle relaxation therapy for anxious, sensitive chronic neck pain patient, then we evaluated her Visual Analogue Scale in reference to subjective feelings of pains every other day at 9 PM. In conclusion, We found that deep breathing and muscle relaxations helped reduce the feeling of pains for those who suffered from anxiety, tensional pains. Therefore, relaxation therapies are necessary methods for pain controls as well as physical treatments.

Stress is accompanied by changes in the responses of the autonomic nervous system, and the heart rate variability (HRV) index is a quantitative marker that reflects autonomic responses induced by stressors. In this study, we observed changes in the autonomic responses induced by combinations of 30% oxygen administration and color light for stress relaxation. In all, 42 participants produced stress symptoms over the preceding two weeks, as rated on the stress response scale. After stress assessment, they were exposed to three therapeutic conditions, and electrocardiogram (ECG) signals were recorded before, during, and after therapy. The three therapy conditions consisted of only 30% oxygen administration with white light, a combination of 30% oxygen and orange light, and a combination of 30% oxygen and blue light. The HRV indices extracted from ECG signals were heart rate (HR), the standard deviation of the RR interval (SDNN), the mean square root of consecutive RR interval difference values (RMSSD), the low frequency component of HRV (LF), the high frequency component (HF), and the LF/HF ratio. These indicators were used to compare mean values before and after therapy. The results showed that HR and the LF/HF ratio were significantly lower after therapy than before it. In particular, the condition with 30% oxygen and blue light yielded significantly greater RMSSD and HF increases, as well as decreases in LF/HF ratio than in other two conditions. Our results suggest that therapy with 30% oxygen and blue light is the most effective for the relaxation of stress, which implies autonomic balance by parasympathetic activation.
