Objective : This study was to examine a relationship among subjective psychological stress, physical stress response and oxidative stress. Methods : The subjects were consisted of 87 healthy volunteers. To assess subjective psychological stress, SRI(stress response inventory) was completed. To assess psychological and physical stress response, HRV(Heart Rate Variability) were tested. To assess oxidative stress, d-roms(Derivatives of reactive oxygen metabolites test) test was conducted. Subjects were divided into 3 groups depending on SRI(Stress Response Inventory) score, low stress response(LSR: lower than 30 percentile), Medium(MSR: 30-70 percentile) and high stress response(HSR: higher than 70 percentile). The Relationship between Stress Response and Oxidative Stress was estimated by correlation and One-way ANOVA analysis. Results : There were no significant differences of demographic data among 3 groups. There was a significant difference of oxidative stress among 3 groups. Conclusion : Our results suggest that there is a weak positive correlation between subjective psychological stress and oxidative stress. There is a significant difference of oxidative stress between HSR group and LSR group.

This study investigates the perception of different fabrics by consumers when provided with a video clip with rustling sounds of the fabric. We utilized sportswear products that are currently on the market and evaluated the emotional response of internet shoppers by measuring the physiological and psychological responses. Three kinds of vapor-permeable water-repellent fabric were selected to generate video clips each containing the fabric rustling sound and images of exercise activities wearing the sportswear made of the respective fabric. The new experimental website contained the video clips and was compared with the original website which served as a control. 30 subjects, who had experience to buy clothing online, took part in the physiological and psychological response to the video clip. Electroen-cephalography (EEG) was used to measure the physiological response while the psychological response consisted of evaluating accurate perception of the fabric, satisfaction, and consumer interest. When we offered video clips with fabric's rustling sound on the website, subjects answered they could get more accurate and rapid information to decide to purchase the products than otherwise they do the shopping without such information. However, such rustling sounds somewhat annoy customers, as proved psychological and physiological response. Our study is a critical step in evaluating the consumer's emotional response to sportswear fabric which will promote selling frequency, reduce the return rate and aid development of new sportswear fabric further evolution of the industry.

We recognize analysing and quantifying an effect of light and colors on people' psychological response changing according to environmental conditions as important. Therefore, this study intends to improve efficiency in realizing emotional design that contributes to creation of helpful and pleasant interior using architecture that is able to refresh human emotion or light and colors which are important factors in interior design. For the purpose, this study analyses an effect of colors in interior space and the effect of interaction between light and color through modeling to identify types of psychological response. And it is to present a generalized conclusion through an analysis of meaning of the two effects. The ultimate goal of this study is to identify the value and possibility of actual design. This study measures response on questionnaire through representative vocabulary by abstracting based on evaluation image selected through the 1st and 2nd preparatory research and grouping similar words. In next step, images represented both by light and colors are presented as virtual space and for data input and analysis based on psychological response corresponding to each image, this study uses SPSS 11.0 statistical package program to analyse data collected. The space to be experimented is a livingroom, a center of residential area.

It is important to understand psychological and physiological responses of occupants who seated in a chair in order to shape a comfortable indoor official environment. So it is needed to find out optimal seated conditions. The purpose of this study was to explore optimal condition of seat air conditioning control based on psychological or subjective responses (perceived temperature and comfort sensation) and physiological responses (heartrate variability; HRV). To do this, experimental conditions were designed by the difference of indoor temperature and seat air conditioning temperature. In the experiment 1, seven experimental conditions were designed with one control condition which was not used seat air conditioning system, and six experimental conditions which the difference of indoor temperature and seat air conditioning temperature ($-1^{\circ}C{\sim}-6^{\circ}C$). In the experiment 2, four experimental conditions were designed with one control condition and three experimental conditions ($-3^{\circ}C{\sim}-5^{\circ}C$). In addition, participants' psychological or subjective response was measured by CSV (comfort sensation vote) and PTS (perceived temperature sensitivity) as a psychological or subjective response, and heartrate variability was measured as a physiological response. As a result, in the experiment 1, it was reported that the optimal conditions of seat air conditioning control based on participants' psychological or subjective comfort were from $-3^{\circ}C$ to $-5^{\circ}C$ experimental conditions. In addition, in the experiment 2, it was reported that the optimal condition of seat air conditioning control based on participants' physiological comfort was $-4^{\circ}C$ experimental condition. These results suggested that seat air conditioning could affected to comfort sensation of occupants in an appropriate range, rather than unconditionally.

This study examined difference in the responses of children and therapists depending on children's problem type(internalization or externalization) and the therapists' levels of psychological burnout. Play therapy' cases (March 2010 ~ September 2011) were successfully concluded in more than 36 sessions, which targeting 14 children aged 4~9 who had emotional and behavioral problems and two therapists who consulted with the children. To examine the change in the play therapy stepwise process in this case, the responses in the children and the therapists were examined by dividing the stages of therapy into the early stage, the middle stage, and the late stage. The Results showed that (1) the children's response during the play therapy process were not significant different for both types of children's problems. Moreover, there were no differences with different levels psychological burnout by the therapist. (2) A change in the children's response during the play therapy process was noted in both children who had internalization problem and in those who had externalization problems. Moreover, according to the therapist's levels of psychological burnout, a change in the children's responses was indicated in the play therapy process. (3) The therapist's responses in the play therapy process did not show significant difference according to children's problem type or therapists' levels of psychological burnout. (4) A significant difference was noted in the responses between the therapists experiencing psychological burnout depending on their level.

Psychological action is physiological response of outernal stimulus. Physiological response is accompanied b physiological signals which are EEG, EMG, GSR, ECG, BP, and tec. Physiological signals are recently studied for determination of human phychological state. Psychological activity causes electric potential of brain. Physiological signal is considered as measurement of human psychological state. Aditory sensibility which is one of the sense of human may determine differences between positive and negative feeling. EEG and GSR variation with auditory quality of stimulus can be define human negative and positive mental state. This study is to characterize parameters which can determine negative and positive psycholigical state of human.

This study was conducted to examine the usage effects of an augmented reality head-up display (AR-HUD) system on the risk perception and psychological changes of drivers. To do so, we conducted an experiment to collect the driver response times for vehicles and pedestrians as their risk perception behavior, and used a driving behavior determinants questionnaire consisting of Problem Evading, Benefits/Sensation Seeking, Anti-Personal Anxiety, Anti-Personal Angry, and Aggression factors for collecting the psychological characteristics of the drivers. Thirty drivers were randomly assigned into an in-vehicle AR-HUD using group and a control group. As a result, the Anti-Personal Anxiety and Anti-Personal Angry factors were negatively correlated with the response time for the control group. In contrast, these results were not shown for the in-vehicle AR-HUD system using group. These results indicate that the in-vehicle AR-HUD system may partially induce a relaxation of tension or stress for drivers with a high level of interpersonal anxiety. Therefore, the in-vehicle AR-HUD system might contribute to not only the visual safety driving behaviors of drivers, but also to their psychological driving safety with specific characteristics.

This study was conducted to identify the differences in physiological and psychological effects between artificial and natural plants. Artificial and natural plant pots consisting of the same species and forms were prepared, and 40 subjects were asked to look at these plants for 3 min, and psychological responses were measured. Semantic differential, profile of mood states, and positive and negative affect schedule were used as psychological response measurement scales. As a result, regardless of the difference in plant material, as plants were viewed, negative emotions decreased in psychological terms. This result suggests that artificial plants can replace natural plants and that the use of artificial plants can be improved if planting natural plants is difficult because there is no difference in the psychological effects provided by artificial and natural plants.
