The purpose of this research Is to inquire into the aspects of consumers' perception of age and their lifestyle and to reveal the effect of variability in spending behaviors themselves. A survey was carried out regarding the consumers of the new elderly generation aged 55 and above. 561 respondents were surveyed. residing in Seoul and Metropolitan areas. Factor analysis from the exploratory reconnaissance, Cronbach's $\alpha$, K-average community and multivariate analysis, multi-recurrence and crossing analysis($\chi^2$ verified), were used for statistics analysis. In conclusion, the cognitive age only shared a marginal relationship with lifestyle, most people in their forties stood out in this part of the research. The change of the cognitive age and lifestyle of the new elderly generation is expected to be a variable in the clothing purchasing behavior in the future. As the population of the new elderly generation increases, there is a need for changing views towards the new elderly generation and there is no doubt that it is a main target within marketing trends in the elderly generation industry.

Consumers' shopping experience has recently expanded to mobile and social networks; in addition, online fashion retailers started to focus on real-time interaction services as an emerging marketing tool. This study explores the consumer' shopping experience based on social live streaming services (SLSS) to investigate consumer's response behavior and effects through perceived service quality. An online survey method was conducted and a total of 186 female consumer panels were collected. The results indicate that cognitive communion of co-experience had a significant effect on perceived SLSS service quality (responsiveness, contents informativeness, playfulness, system availability). Service quality of SLSS (responsiveness, contents informativeness, and playfulness) had significant effect on trust in SLSS seller while system availability had no significant effect. Also, trust in seller showed significant effect on purchase intention. Last, it was confirmed that the moderating effect of purchasing experience of SLSS was significant in the relationship between cognitive communion and responsiveness/playfulness. There was also an additional significant moderating effect of purchasing experience between system availability and trust in seller.

Purpose: The purpose of this study is to investigate the effects of relaxation on stress and blood pressure of the college students induced by a cognitive distress game. Methods: The subjects for this research were 18 individuals whose stress index scores were below 4.0 (Asan city). The 18 subjects were divided into two, 9 students were assigned to the experimental group and the other 9 students to the control group randomly. Survey was used to gather data to recognize general characteristics and the level of stress and blood pressure were measured before and after cognitive distress game and relaxation. The gathered data were analyzed with frequency, $X^2$-test, Wilcoxon signed ranks test and Mann Whitney U test using SPSS 14.0 program. Results: Both level of stress and blood pressure displayed a statistically significant difference pre and post cognitive distress game. Relaxation had a statistically significant effect on level of stress. Relaxation, however, did not have statistically significant effect on blood pressure. Conclusion: The above results suggest that while relaxation was effective in reducing level of stress for college students, and therefore recommendable as a means to deal with stress. However, to investigate the effects on physiological index such as blood pressure, further research is needed.

Purpose While the popularity of C2C auction platforms such as eBay is gradually decreased, this domain is still undermined to explain online bidding behaviors. Online bidders sometimes engage in impulsive bidding due to some of the online auction characteristics. Therefore, this study develops and tests a model of the impulsive bidding exhibited by online bidders in C2C auction platforms. Based on S-O-R framework, our model posits that both perceived time-pressure and competition intensity affect cognitive absorption which ultimately influences the impulsive bidding. Design/methodology/approach This study collected survey data from 214 C2C auction participants, who have prior experience on impulsive bidding and tested both measurement model and structural model by using CB-SEM (covariate-based structural equation modelling) technique. In this study, by using AMOS 20.0, we tested the measurement model for its overall fit, item reliability, and validity and further conducted the structural model to test our proposed hypotheses. Findings Based on our results, we found that perceived tim-pressure and competition intensity were positively related to cognitive absorption. We also found that the cognitive absorption was positively associated with impulsive bidding behavior. In this study, by developing our research model in S-O-R framework, we provide an alternative theoretical mechanism to describe online impulsive bidding behavior.

Purpose: The purpose of the study was to identify the mediating effects of social support and self-efficacy between academic stress and college adjustment in physical therapy students. Design: Survey. Methods: 75 subjects were surveyed about the level of academic, Academic Stress, College Adjustment, Social Support, Self-Efficacy, and self-control. To confirm the cognitive function on brain activity were evaluated. Results: First, College students have higher academic stress and lower college adjustment. Higher social support and self-efficacy have lower academic stress and better college adjustment. Second, students with high academic stress need constant attention to increase their social support and programs to reduce academic stress. Third, students with high academic stress, low social support, and low self-efficacy can increase their cognitive strength through the brain wave thereby reducing the academic stress they are currently feeling. Conclusion: In order to improve the College Adjustment, it is considered that it is important to increase the cognitive function through brain train along with the development of a student management program that can reduce academic stress and increase social support and self-efficacy.

The aim of this study was to evaluate the effects of a nutrition education program for the elderly at a public health center located in Jinhae city. The one group pretest and posttest design was conducted using self-administered questionnaire survey. Nutrition education lessons based on social cognitive theory (2 hours/lesson, 3 times) were provided to 27 female elderly(${\geq}65$ yrs) for a month. After the nutrition education, number of exercise increased and preference for sweetness decreased significantly (p<0.05). The outcome expectations, the knowledge of nutrition (p<0.001), and behavioral capability (p<0.05) score were significantly increased. There were significant increases in all nutrient intake. NAR was increased significantly in protein, calcium and vitamin C (p<0.01), dietary fiber, iron, zinc, thiamin, niacin and folic acid (p<0.001), and riboflavin (p<0.05). INQ was increased significantly in thiamin, vitamin B6 and niacin (p<0.05), and dietary fiber (p<0.01). The score of nutrition education satisfaction was high (4.52). The results of this study suggested that the nutritional education program based on social cognitive theory had a positive effect on dietary behavior changes, and nutrition intake status among female elderly even after short-term intervention.

Students' engagement is very important for effect science learning. Multidimensional approaches on students' engagement defines engagement in three ways which includes cognitive, behavioral, and cognitive engagement. Based on the multidimensional approaches on students' engagement, this study identified latent groups of elementary students characterized by patterns of cognitive, behavioral, and emotional engagement in science classes. This study also compared students' perceptions of their engagement in general science classes and small-group activities by the latent groups. 377 elementary students were involved in this study. 5-scale Likert survey were used in order to investigate students' engagement in science classes. Latent class analysis using Mplus program identified 3 latent groups of students engagement in science classes: Highly engaged, moderately engaged, and minimally engaged in three ways of engagement. The mean scores of cognitive, behavioral, and emotional engagement were significantly different by three latent groups. In addition, there were significant difference in students perceptions on participating experiments activities and carefully listening of teacher among latent groups. However, there was no significant difference in students' perceptions on their actions during small-group activities. Educational implications were discussed.
