Change of Physiology and Emotion According to Plant-decoration Activity in Workers

Abstract

This study was conducted to investigate the change of workers physiology and sensitivity according to the plant decoration activity using electroencephalographic (EEG), electrocardiogram, and semantic differential (SD) methods on 31 male and female workers in their twenties. Plant decoration activity and writing documents on a computer (WDOC) were carried out for 10 minutes each. The relative slow alpha power spectrum (RSA) has been highly exhibited at most measurement points at plant decoration activity compared to WDOC, and ratio of alpha to high beta spectrum (RAHB) was higher in the parietal lobe responsible for visual function in charge of visual function and showed stable and relaxed effect with little stress or tension. In addition, the relatively fast alpha power spectrum (RFA), which is responsible for visual function, after WDOC was higher than after plant decoration activity in the left parietal lobe (P <.05). Although not statistically significant, the relative high beta power spectrum (RHB) and the ratio of mid beta to theta (RMT), which are stress concentration indexes with tension, were highly regarded as a whole when performing WDOC. There was little difference in heart rate between after both activities. However, high frequency (HF) component indicating parasympathetic nervous system activity was more highly active after WDOC than Planting decoration activity, and the low frequency (LF) component indicating sympathetic nervous system activity tended to be lower after WDOC than after planting activity meaning that plant activity have a sense of stability than WDOC and these results were similar to brain wave analysis. In addition, the sense of comfort, naturalness, calm were significantly higher when the plant decoration activity was performed than when the WDOC was performed in the SD emotional vocabulary survey. These results could be interpreted that plant decoration activity induced more physiologically and psychologically stability and relaxation than WDOC, and enhanced attention ability in appropriate awakening state.

Effects of Plant Cultivating Activity for Reducing Parental Stress

“…These results are supported by those of Kwak (2004), Lee (2006) and Ulrich (1981) that plant cultivating activities in artificial spaces or activities that utilize natural materials have not only environmental effects but also emotional effects such as psychological stability, serenity and stress relief. In addition, these results are similar to those of other studies such as Jang et al (2017) and Lee et al (2013). Jang et al (2017) found plant decorating activities were more effective in improving the physiological and psychological stability and relaxation of workers than document writing activities.…”

“…In addition, these results are similar to those of other studies such as Jang et al (2017) and Lee et al (2013). Jang et al (2017) found plant decorating activities were more effective in improving the physiological and psychological stability and relaxation of workers than document writing activities. Lee et al (2013) was conducted among prisoners to be released and it was found that the level of cortisol in the saliva and depression of the experimental group statistically significantly decreased after participating in horticultural activities while there was no statistically significant change in the control group.…”

Effects of an Agro-Healing Activity Program on the Physiological Condition of Adults with Chronic Metabolic Diseases

“…To identify the effects of agro-healing activities and strolling on the physiological conditions of patients with chronic metabolic diseases, and the following physiological conditions of a total of 11 male and female participants of for the selection of subjects in general brain studies (Jang et al, 2017;Lee et al, 2009;Son et al, 1998Son et al, , 1999. The final subjects were selected after conducting and analyzing the results of screening tests on the recruited subjects to ensure the selected subjects were suitable for this test as a patient with chronic metabolic disease.…”

Neurophysiological Changes in Elementary School Parents after Plant Cultivation Activity

“…Before and after measuring the EEG and ECG of the subjects, their blood pressure and pulse were measured using a portable digital blood pressure monitor (HEM-1000, OMRON, Japan) that uses an oscilloscope. Their EEG and ECG were measured using the method suggested by Jang et al (2017) after adjusting it to the conditions of this experiment.…”

“…Subjects were recruited through an offline bulletin board in an elementary school located in Jeonju and were selected among parents who met the selection criteria for general brain-related studies (Lee et al, 2009;Jang et al, 2017;Son et al, 1998Son et al, , 1999. A total of 27 parents were selected and they were fully informed of the purpose of this study, the content Journal of People, Plants, and Environment Vol.…”
