This study was carried to get detailed information about the analeptic effect of yohimbine on succinylcholine muscle relaxant. Succinylcholine was administered intra- venously at a dose rate of 0.05 mg per kg of body weight and then ten minutes after the succinylcholine injection, yohimbine was administered intravenously at a dose rate of 0.1 mg per kg of body weight. The results obtained were as follows. 1. Induction time of muscle relaxation was fast and favourable as 38 seconds. 2. Mean arousal time and mean walk time were significantly shortened by yohimbine administration in the dogs immobilized with succinylcholine (p＜0.01). 3. Heart rate was slightly increased after succinylcholine administration, and increased significantly after yohimbine administration compared to the control group (p＜0.05). 4. Glucose concentration was slightly increased after succinylcholine administration, and decreased after yohimbine administration compared to the control group.

Recently, due to the introduction of high-tech equipment in interactive exhibits, many people's attention has been concentrated on Interactive exhibits that can double the exhibition effect through the interaction with the audience. In addition, it is also possible to measure a variety of audience reaction in the interactive exhibition. Among various audience reactions, this research uses the change of the facial features that can be collected in an interactive exhibition space. This research develops an artificial neural network-based prediction model to predict the response of the audience by measuring the change of the facial features when the audience is given stimulation from the non-excited state. To present the emotion state of the audience, this research uses a Valence-Arousal model. So, this research suggests an overall framework composed of the following six steps. The first step is a step of collecting data for modeling. The data was collected from people participated in the 2012 Seoul DMC Culture Open, and the collected data was used for the experiments. The second step extracts 64 facial features from the collected data and compensates the facial feature values. The third step generates independent and dependent variables of an artificial neural network model. The fourth step extracts the independent variable that affects the dependent variable using the statistical technique. The fifth step builds an artificial neural network model and performs a learning process using train set and test set. Finally the last sixth step is to validate the prediction performance of artificial neural network model using the validation data set. The proposed model is compared with statistical predictive model to see whether it had better performance or not. As a result, although the data set in this experiment had much noise, the proposed model showed better results when the model was compared with multiple regression analysis model. If the prediction model of audience reaction was used in the real exhibition, it will be able to provide countermeasures and services appropriate to the audience's reaction viewing the exhibits. Specifically, if the arousal of audience about Exhibits is low, Action to increase arousal of the audience will be taken. For instance, we recommend the audience another preferred contents or using a light or sound to focus on these exhibits. In other words, when planning future exhibitions, planning the exhibition to satisfy various audience preferences would be possible. And it is expected to foster a personalized environment to concentrate on the exhibits. But, the proposed model in this research still shows the low prediction accuracy. The cause is in some parts as follows : First, the data covers diverse visitors of real exhibitions, so it was difficult to control the optimized experimental environment. So, the collected data has much noise, and it would results a lower accuracy. In further research, the data collection will be conducted in a more optimized experimental environment. The further research to increase the accuracy of the predictions of the model will be conducted. Second, using changes of facial expression only is thought to be not enough to extract audience emotions. If facial expression is combined with other responses, such as the sound, audience behavior, it would result a better result.

Yoga is an ancient Indian system of life, encompassing various practices including practices for self-discipline and also for regulating the health states of the individual, being practiced for thousands of years. The present study aims at understanding the effect of two high frequency breathing practices over autonomic nervous system. Forty healthy male volunteers of age $21{\pm}2$ years with $9{\pm}3$ months of Yoga practice experience were recruited. The two high frequency Yoga breathing practices, kapalabhati (KB) and bhastrika (BH) were given as interventions randomly on either of the two days to minimise laboratory bias. They were assessed before and immediately after the interventions for heart rate, respiratory rate, heart rate variability (HRV), blood pressure and peripheral oxygen saturation. There was a significant increase in heart rate (p<0.01; p<0.001), systolic blood pressure (p<0.01; p<0.001), NN50 (p<0.01; p<0.001) component of HRV for both KB and BH groups respectively. There was a significant reduction in respiratory rate in both the groups (p<0.001, and p<0.05, BH and KB respectively) immediately following intervention. A significant increase in LF component of HRV and reduction in Diastolic blood pressure and high frequency (HF)component following KB was also observed (p<0.05, for all comparisons). The Mean peripheral oxygen saturation remained unaltered in both the groups (p>0.05).The results suggest that high frequency yoga breathing practices induce physiological arousal immediately as evidenced by increased blood pressure and heart rate. The sympathetic arousal was more following KB session as evidenced by an increased diastolic blood pressure, LF power and a decrease in HF power of HRV as compared to the BH session.

The purpose of this study is to explore the experience of participants in the adventurous leisure activities and to examine the structural relations of the cognitive experience, the emotional experience and adherence intention. Robust quantitative measures were developed from rich qualitative data. The five dimensions selected from two preliminary tests were being away, technical enhancement, fascination with nature, challenge, and interpersonal trust. The cognitive dimensions have a significant effect on the emotional arousal - pleasure dimension. Our study also shows a positive causal relationship between emotional experience and adherence intention. Implications of this study include 1) a developed questionnaire for measuring the cognitive experience dimension of adventure leisure and establishing a foundation for future research, and 2) an identified psychological model among cognitive, emotion, and intention. We offer opportunities to better understand the psychological factors that motivate participation in adventure leisure.

Common theories of affect underscore valence and arousal dimensions or specific emotion. However, given the role of affect in transacting social behavior, sociality may determine the subjective experience and interpersonal response to positive stimuli. The current study examined the relationships between social positive affect and perspective taking as well as positive coping. One potential moderating effect of agreeableness on these relations was also examined. In two experiments, film segments induced socially and non-socially generated positive affects. We hypothesized and found that positive affect associated with sociality would enhance perspective taking ability and positive coping, while non-social positive affect would not. Moreover, these effects varied as a function of the level of agreeableness. These findings suggest that the social/non-social dimension influenced which positive affects elicited perspective taking and positive coping, which could not be explained by differences in subjective emotional valence or arousal. Taken together, these findings have important implications, as they point toward a previously overlooked relation linking sociality to positive affect.

As information and communication technologies (ICTs) become more advanced, consumers are able to experience retailing activities such as searching for products and services in online retail shops and for Internet-exclusive branded contents. Specifically, fashion retailers are facing the need to develop more novel experiential design than one another to maximize customers' experience in Internet websites and secure sustainable competency. Confirming methods of organic integration of experiential and visual features of both online and mobile channels is an important aspect of the study of extended consumers' interfaces of retail channels. Mehrabian and Russell's stimulus-organism-response (S-O-R) paradigm and Sugiyama and Andree's attention, interest, search, action, and share (AISAS) model were used for this research. Specifically, the present study considered the effect of e-commerce website features on consumers' emotional reactions (pleasure and arousal) and the consequent impact on online consumer behaviors (search, action, and share). Hence, plus the self-reported survey methods, each subject's psychophysiological indicators (i.e., pleasure and arousal) were measured to obtain more objective and reliable data and to redeem the results of the self-reported survey. Findings revealed the implications of the e-commerce website feature by comprehending the S-O-R paradigm and AISAS model and extending the understanding of the role of variables associated with comprehended frameworks based on psychophysiological data.

The purpose of this paper is to develop the algorithm of human arousal inducing interface using steady-state visual evoked potential(SSVEP) and its verification through experiments. In order to develop the model, computer-based SSVEP program simulation is preliminary performed. From the results of the simulation, stimulus pattern is decided to checkerboard and SSVEP frequency range is set into beta wave (13~30Hz). After the experiment on proving the effect of SSVEP flashing stimulation while driving by installing it at the location of people mostly falling asleep in the highway, the result confirms that both during the night and the day, after SSVEP flashing stimulation, a wave Beta immediately increases and the subjects keep high stimulation for the 5 minute maintaining stage.

This study aims to analyze the effect of emotional response from dining out experience on satisfaction after dining out based on the customers who have visited a luxurious Korean restaurant. For this study, it designed a research model through literary research and derived hypotheses. For the empirical analysis, 250 copies of the questionnaire using the self-administered method were distributed and 230(94%) copies were collected. Among them, 220(88%) copies were used for the analysis. SPSS WIN Version 12.0 statistical package program was used for the analysis of data processing, the frequency analysis, reliability analysis and factor analysis were operated, and the hypothesis testing was verified by the regression analysis. The results of the analyses are as follows. For the hypothesis that "the dining-out consumption pattern will have a significant effect on the emotional response," it was verified that the style which pursues health and the style which is loyal to relationships had significant effects on pleasure while the style which pursues rest didn't. Also, the style which pursues health and the style which is loyal to relationships had significant effects on arousal while the style which pursues rest didn't. For the hypothesis that "emotional response will have a significant effect on satisfaction," it was verified that pleasure and simulation had significant effects on satisfaction. As a result of the study, the current dining-out consumption pattern is changed from the purpose of having meals for the biological needs in the past to considering emotional response such as preferred taste or mood.

The meaning of luxury varies by individuals. The differing luxury perceptions should influence the way individuals react to relevant marketing programs for luxury. Limited research exists on the topic despite interest in luxury segmentation and consumer-oriented values for luxury in marketplaces. Referring to the conceptual framework by Wiedmann et al. (2007), we explored the moderation role of four dimensions of luxury value perceptions (LVP; financial, functional, individual, and social dimensions), in the relationship between in-store emotion and perceived brand luxury. A total of 218 U.S. consumers participated in our online survey using a hypothetical luxury store image. The results revealed the following: First, on the relationship between felt pleasure and perceived brand luxury (PBL), the financial dimension of LVP only showed a significant moderation effect. Second, the effect of felt arousal on PBL was moderated by the financial and social dimensions of LVP. Lastly, the individual dimension of LVP only moderated the relationship between felt dominance and PBL. Theoretical and managerial implications are suggested.

This study identifies key determinants of participation in UCC services. Incorporating insights from the flow theory, we examine the effects of psychological factors of social presence, self expression, arousal, and challenge as well as web-site characteristics variables of media easiness, contents usability, and immediateness. We have done a sample survey of internet users and collected 260 responses. Using Windows SPSS/PC 12.0 Package, we have performed statistical analyses including a correlation analysis, a factor analysis, and a multiple regression analysis. The result of the study is as follows. Psychological variables of perceived social presence, self expression, arousal, and challenge all show positive significant effect on participation in UCC service. Among web site characteristics, media easiness, which consists of a web structure that is easy-to-use, user friendliness, and personalized service, demonstrates a positive significant effect on participation in UCC services. Immediateness also has a positive significant effect. Some of the practical implications of the result are follows. We should improve user access to platforms of UCC service by opening up platforms. This will heighten perceived challenge which has the strongest influence on participation in UCC services. We need to focus on multimedia services and adjust to the cultural code of netizen who crave for visual expressions and on the spot on-line activities. Also suggested is that contributions made by participants need to be acknowledged through such provisions as profit sharing. Needs for individualized service, which is an aspect of media easiness, should also be addressed. Participants tend to value individuality while at the same time accepting broader trends. Information services need to be customized for individuals. In UCC centered internet businesses, netizen consumers are presumer. They are consumers and producers at the same time, and consumer needs should also be explored for the success of internet businesses.
