The aim of this study was to investigate the effects of sowthistle (Ixeris dentata, IXD) on development and expression of nicotine-induced locomotor sensitization and underlying neuronal activation reflected by c-Fos expression in rats. Rats were pretreated with IXD 30 min before a daily injection of nicotine during an 8-day development phase and then challenged with nicotine after a 6-day withdrawal period. In another set of experiments,same IXD doses were administered once 30 min before nicotine challenge. Daily IXD treatment during development phase was not effective in blocking nicotine-induced locomotor sensitization in rats. However, a single IXD treatment after the development and withdrawal periods of nicotine sensitization significantly alleviated sensitized locomotor behavior on day 15. These behavioral results were coincident with significant inhibition of nicotineinduced c-Fos expression in the nucleus accumbens. These results indicated that IXD pretreatment significantly blocked the expression, but not the development of nicotine-induced locomotor sensitization in rats.

Background and objective: Artificial environments have been known to negatively affect neuropsychological activities. Healthcare workers who are under high psychological and physiological stress often spend long hours at a time. Recently, many studies have been conducted to reveal the healing effects of natural environments, but few studies have been conducted on healthcare workers. Therefore, this study aims to investigate the effect of green walls in medical facilities on the hemodynamics of the prefrontal cortex in healthcare workers. Methods: Eleven healthy adults working in a medical institution participated in the experiment, in which they rested for 10 minutes in a room with green walls and in a control room. To compare the physiological and psychological changes between the green wall room and the control room, we used various measurements, such as near-infrared spectroscopy in the prefrontal area (NIRS), heart rate variability (HRV), blood pressure (BP), and pulse rate (PR). Psychological tests were also conducted using the Profile of Mood States (POMS), the State-Trait Anxiety Inventory (STAI), the Perceived Restorativeness Scale (PRS), and the Zucherman Inventory of Personal Reaction Scale (ZIPERS). Results: The oxyhemoglobin concentration in the frontal lobe significantly decreased on both the left and right sides in the green wall room compared to the control room. Green walls significantly activated the parasympathetic nervous system and inhibited the sympathetic nervous system compared to the control room. In addition, psychological reactions increased positive emotions and decreased negative emotions. Conclusion: Green walls in medical facilities could be an effective way to promote physiological relaxation and health by reducing physiological hemodynamics in the prefrontal cortex evoked by psychological stress in healthcare workers. This study implies that green walls can be used as an effective means of stress reduction and relaxation.

This study was conducted to investigate the response of the human body to stress induced by wall recording of subway stations in the city center. The experiment was conducted as a simulation exercise, and six images were selected and produced based on Subway Line 2, a representative underground space in Seoul. The study participants included 24 male and female college students. A three-minute experiment was conducted, during which the participants were shown the control image and green wall image once each. To measure psychological status, the following measurement indicators were used: Semantic Differential, Positive Affect and Negative Affect Schedule and State-Trait Anxiety Inventory. Physiological changes were investigated by tracking participants’ heart rate and blood pressure. Results showed that parasympathetic and sympathetic nerves were activated in the presence of the green wall in the subway station. The psychological evaluation analysis revealed that negative affect toward underground space decreased, while positive affect increased. This study found that the green wall in subway stations has a stable effect on the human body, both psychologically and physiologically. In the future, green walls in underground spaces can be used to reduce psychological stress and increase physiological relaxation.

Manufacturing workers face increased fatigue and stress due to environmental factors in workplace such as noise and vibration. Addressing this issue requires creating conducive rest spaces; however, the existing conditions of rest spaces in manufacturing workplace are subpar and lack sufficient scholarly evidence. This study investigated the effect of nature-based rest spaces on the physical and emotional recovery from fatigue on manufacturing workers. Three manufacturing complexes with nature-friendly rest spaces were selected, and 63 manufacturing workers participated in the study. The measurement tools included the Multidimensional Fatigue Scale (MFS) for fatigue levels, physiological indicators (blood pressure and heart rate), and emotional indicators (Zuckerman Inventory of Personal Reaction Scale; ZIPERS, Perceived Restorativeness Scale; PRS, Profile of Mood States; POMS and State-Trait Anxiety Inventory; STAI). The study compared recovery levels during a 7-minute rest between a space without plants and a space with natural elements. The results indicated a significant reduction in systolic and diastolic blood pressure of participants in green rest spaces compared with those in conventional rest spaces. Regarding fatigue levels, green rest spaces showed a decrease in systolic blood pressure in the middle-fatigue and high-fatigue groups. Positive feelings increased in green spaces, whereas negative emotions decreased, suggesting that short breaks in nature-friendly environments effectively promote workers physical and emotional recovery. Furthermore, this study emphasizes the importance of green space in various work environments to promote well-being in workers.

Background and objective: With an increasing interest in health-related issues in urban environments, there has beengrowing attention to the relationship between green space and psychological states of residents in apartment complexes. This study investigated resident perceptions of green space and their stress responses in an apartment complex. Methods: The psychological stress responses that arose during residents' observation of two types of environments-anindoor living room and an outdoor green space-were investigated through a field experiment. Sixteen healthy adultfemales in child care participated in the within-group comparison study. The semantic differential (SD) method was usedto examine environmental perception, and three psychological tests were administered to quantify stress responses to thetwo environments: the Profile of Mood States (POMS), the Revised Perceived Restorativeness Scale (RPRS), and theZuckerman Inventory of Personal Reactions Scale (ZIPERS). Results: Feeling of pleasure, familiarity, and beauty showed significantly higher scores in outdoor green space than indoorspace. In the POMS analysis, significantly more positive mood states were found in outdoor green space than indoor space. The ZIPERS and RPRS data showed that outdoor green space was more suitable for fatigue recovery because it relievednegative emotions and psychological stress to a greater degree than indoor space. Conclusion: This field study suggested that green spaces have the potential to reduce psychological stress and restorepsychological well-being in female residents. Despite limited exposure to the green space in the apartment complex,improved mood states and positive health-related effects were observed among the participants.
