Purpose: The aim of this study was to examine the effects of a yoga program on perceived stress, stress response and heart rate variability in professionals. Methods: The research design was a quasi-experimental intervention study. The participants were 47 adults with professional jobs consisting of an experimental group with 23 adults and a control group with 24 adults. The duration of the yoga program was eight weeks from July 4 to August 30, 2012. Results: There were significant decreases in the stress response score after the yoga program. No significant changes in perceived stress and heart rate variability were observed between the experimental group and control group. However, there were significant decreases in perceived stress, stress response scale, and heart rate variability for some participants whose stress levels were high. Conclusion: An eight-week-long yoga program could be considered as an intervention to decrease the stress response of professionals even though it might not reduce their perceived stress and heart rate variability. To further analyze the effects of a yoga program in professionals, changes in intervention strength (such as longer periods and frequency) and the development of physiological measures, which would show the co-relationship between perceived stress and physiological response, are necessary in future studies.

This study evaluated the thermal physiological and psychological responses elicited when wearing cold protective jackets with aerogel fillings in two cold environments, one without air velocities and one with air velocities (2.3 m·s-1), at an air temperature of 10℃. The participants were five healthy young males. Measures were taken of physiological parameters, blood pressure (BP), heart rate (HR), core temperature, oxygen uptake (Vo2), and microclimate (temperature and humidity). The psychological parameters evaluated were thermal and wetness sensation. No differences were observed in systolic blood pressure, heart rate, and oxygen intake between the conditions. At tympanic temperature, a significant difference was observed between the conditions during exercise (p<.05); . A significant difference was observed in the microclimate temperature of the clothing according to the airflow, and temperature changes in the chest and back revealed different patterns. Significant differences were observed in thermal sensation (whole body (p<.05), chest (p<.05), back (p<.01)) between airflow conditions. The results therefore indicate that cold protective jackets with an aerogel filling are suitable for people operating in low-temperature and airflow environments.

The purpose of this study was to approve the capability of human sensibility evaluation based on physiological responses and real-time subjective assessments. Three well-trained healthy human subjects were participated in the experiments. We measured physiological responses such as Heart Rate Variability(HRV), Galvanic Skin Response(GSR) and skin temperature under rest and visual stimulation conditions, respectively. Off-time subjective assessments were recorded before and after visual stimulations. Real-time subjective assessments were recorded during visual stimulations. The results of physiological responses and off-time and real-time subjective assessments were quantified and compared. The results showed that the correlation between physiological responses and real-time subjective assessments was high (83%) for both the positive and negative visual stimulation. The correlation between the physiological responses and off-time subjective assessments was high (83%) for the negative visual stimulation but was low (15%) for the positive visual stimulation. Although the current observation is preliminary and requires more careful experimental study, it appears that the correlation between real-time subjective assessment and physiological responses is higher than that of the off-time subjective assessment and physiological responses.

This paper reviewed the relationship between superior leadership and job stress responses, and the moderating effect of age in maintenance area of air force. Based on the responses from 450 air force maintenance persons, the results of multiple regression analysis showed that transactional leadership has negative relationship with physiological stress response, charisma has negative relationship with psychological stress, and individual consideration has negative relationship with behavioral stress. In moderating effects, age has negative effect on the relationship between transactional leadership and physiological stress response, and age has positive effect on the relationship between charisma and psychological stress response.

Controlled mass transport in response to stimuli is essential for drug carriers. The complexity of the signaling system under physiological conditions has led researchers to develop precise nanocontainers that respond to stimuli in the physiological environment. Owing to several reasons, soft nanocontainers such as liposomes and micelles have been investigated for use as drug delivery systems. However, such carriers often suffer from the undesired leakage of drug molecules. In contrast, inorganic nanocontainers are robust, and their surfaces can be easily functionalized. For example, mesoporous silica nanoparticles equipped with gatekeeper molecules are increasingly being used for the controlled release of drug molecules in response to the desired stimuli. Since the development of the first hybrid nanocontainer comprising molecular machines, multiple versions of such gatekeeper systems featuring significantly improved stability and precise response to stimuli have been reported. In this study, various methods for incorporating photoresponsive nanocontainers with porous channels are developed.

In this study, we investigate the physiological response of olive flounder, Paralichthys olivaceus and Japanese croaker, Nibea japonica, on a series of rising water temperatures (WT). At 1, 9, and 17 days, WT increased from 23℃ (control) to 26, 29 and 32℃ within 6 hours, respectively, and then maintained for 96 hours. At 5, 13, and 21 days, WT decreased from each WT to 23℃ within 6 hours and was maintained at 23℃ for 96 hours. Blood were collected at 0, 1, 5, 9, 13, 17, 21, and 60 days. In both species, hematocrit, red blood cell and hemoglobin of stressed groups were lower than non-stressed group at 13 days. The osmolality of stressed group was lower than non-stressed group at 21 and 60 days. In olive flounder, hemoglobin of stressed groups was lower than non-stressed group at 21 and 60 days, respectively, but osmolality of stressed group was higher than non-stressed group at 9 days. In Japanese croaker, hematocrit, red blood cell and hemoglobin of stressed groups were higher than non-stressed group at 21 and 60 days, respectively, and osmolality of stressed group was higher than that of non-stressed group at 1 day. At 1, 17, and 21 days, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of stressed group were higher than non-stressed group in olive flounder. In Japanese croaker, AST and ALT of stressed group was lower than non-stressed group at 17, 21, and 60 days. The cortisol of olive flounder increased with increasing WT, but those of Japanese croaker increased with decreasing WT. In both species, the glucose increased with increasing WT. After changing WT, lactic acid of olive flounder and Japanese croaker were not significantly different. The physiological response of olive flounder increased directly to the increase in WT, and Japanese croaker contrasted with olive flounder.

American sycamore seedlings were grown in chambers with two different ozone concentrations ($O_3$-free air and air with additional $O_3$) for 45 days. Both the control and the $O_3$ chambers included non-fertilized and fertilized plants. After 18 days of $O_3$ fumigation, seedlings were placed in a clean chamber for 27 days. Seedlings under ozone fumigation showed a significant decrease in pigment contents and photosynthetic activity, and a significant increase in lipid peroxidation. Fertilization enhanced physiological damage such as the inhibition of photosynthetic activity and the increase of lipid peroxidation under ozone fumigation. During the recovery phase, the physiological damage level of seedlings increased with ozone fumigation. In addition, physiological damage was observed in the fertilized seedlings. Superoxide dismutase (SOD) and glutathione reductase (GR) activities of $O_3$-treated seedlings increased up to 33.8% and 16.3% in the fertilized plants. The increase of SOD activity was higher in the fertilized plants than in the non-fertilized plants. Negative effects of ozone treatment were observed in the biomass of the leaves and the total dry weight of the fertilized sycamore seedlings. The $O_3$-treated seedlings decreased in stem, root and total dry weight, and the loss of biomass was statistically significant in the fertilized plants. In conclusion, physiological disturbance under normal nutrient conditions has an effect on growth response. In contrast, in conditions of energy shortage, although stress represents a physiological inhibition, it does not seem to affect the growth response.

The purpose of this study was to evaluate the comfort of PET clothing treated by UV. The physiological responses of the human body were investigated. Mean skin temperature and physiological signals such as Electroencephalogram (EEG), and heart rate (Electrocardiogram, (ECG)) were examined for 20 minutes during stable wearing conditions. Mean skin temperature was measured every two seconds using Ramanathan's method. Physiological responses were measured using Biopac MP100 series and analyzed using the software, Acqknowledge 3.5.2. Psychological effects were analyzed every five minutes. Comfort of untreated PET clothing decreased with the passage of time. Compared with PET clothing untreated, treated for 30 minutes, and treated for 90 minutes, the analysis of EEG showed that PET clothing treated for 90 minutes was the most comfortable after 20 minutes. In addition, the interval of the heart rate shown on the ECG was the highest in PET clothing treated for 90 minutes. Skin temperature was the lowest in PET treated for 90 minutes. We thus conclude that suitable UV irradiation would improve comfort.
