Although innate color preference of motile organisms may provide clues to behavioral biases, it has remained a longstanding question. In this study, we investigated innate color preference of zebrafish larvae. A cross maze with different color sleeves around each arm was used for the color preference test (R; red, G; green, B; blue, Y; yellow). The findings showed that 5 dpf zebrafish larvae preferred blue over other colors (B > R > G > Y). To study innate color recognition further, tyrosinase mutants were generated using CRISPR/Cas9 system. As a model for oculocutaneous albinism (OCA) and color vision impairment, tyrosinase mutants demonstrated diminished color sensation, indicated mainly by hypopigmentation of the retinal pigment epithelium (RPE). Due to its relative simplicity and ease, color preference screening using zebrafish larvae is suitable for high-throughput screening applications. This system may potentially be applied to the analysis of drug effects on larval behavior or the detection of sensory deficits in neurological disorder models, such as autism-related disorders, using mutant larvae generated by the CRISPR/Cas9 technique.

This study investigates the multi-dimensional structure of fashion store window creativity and examines its effects on consumer responses. Through an expert evaluation survey, this study proposes that fashion store window creativity involves originality, relevance, and artistry. Two experiments are conducted to test the proposed hypotheses. Consumers' emotional responses to the level of window creativity are collected using psychophysiological and self-report methods. Fashion store window creativity has positive effects on psychophysiological affective responses. When the three dimensions of creativity are specified as explanatory factors of emotional responses, relevance and artistry show positive effects on arousal and pleasure, whereas originality has a negative effect on pleasure. Its effect on attitudes is mediated by arousal and pleasure; in addition, the effect on entering intentions is mediated by arousal. Attitudes toward window display also have a positive effect on entering intentions. This study extends existing research on creativity in marketing into the context of visual merchandising in fashion store windows. Findings provide meaningful implications in that the effects of fashion store window creativity on emotions affect consumer attitudes and behavioral intention. By adopting multiple approaches in the empirical phase of this study, the findings are built on strong reliability and validity.

The purpose of this study was to examine the differences of Psycho-social environments by the variables of sex and type of school. Subjects in this study were consisted of 1.011 adolescents drawn from 11 high schools in Cheongiu city and Choeongwon gun. For data analysis. t-test and three-way ANOVA were conducted by SPSSWIN program. This results were as following: Boys' high school students who having romantic partners had lower school adjustment and behavioral adjustment than those without romantic partners. Girls' high school students who having romantic Partners had lower peer relationships and behavioral adjustment than those without romantic partners. Also. regardless of school types. students with romantic Partners had lower school adjustment and behavioral adjustment than those without romantic partners. In an academic high school. students with romantic Partners had negative family relationships. whereas in commercial high school. students with romantic partners had Peer relationships more negatively than those without romantic Partners. This results suggest that adolescents' romantic partners be important factor of social-Psychological development. Especially. romantic partnership would be critical to induce problem behavior such as maladjustment and negative relationships in the environments of family and school.

This research investigates the media consumers' behavior with behavioral economics perspective, especially regarding TV content viewers' behavior; how do online communications influence TV viewers' decision when choosing a new TV content among options. We focus on quantity and attribute of comments or reactions on the online news articles. We analyze that online communications data, which were generated before the first broadcast, affect the TV content consumers' choice for a new TV series. Here we identify a predicted utility, experienced utility and distinction bias in TV media consumption to find the effectiveness of the first viewing choice on whole TV series' episodes. To avoid the crucial influence by exogenous factors, such as season and social issue, the test was done with specific conditions. This research found that the total number of reactions to the comments by itself positively affects the audiences' decision-making behavior for a new TV content choice. This influence was regardless of favor/ non-flavor reactions. This study contributes to the literature on media economics and management by exploring the media content users' consuming behavior and making a first step for finding an important influencer on the media content consumption.

The study examines factors that influence shopping intention of online consumers in Vietnam. Studied factors include consumers' attitude, subjective norms, perception of behavioral control, perception of usefulness, perceived risks and trust. The expansion of Theory of Planned Behavior (TPB) and Technology Acceptance Model (TAM) are used as basic theories. We have surveyed people who have experiences on online shopping. There are 836 selected questionnaires that are qualified for data processing. The collected data are analyzed through a process which starts from scale reliability test to exploratory factor analysis (EFA), correlation analysis and regression analysis. The results show that shopping intention of online consumers are positively affected by their attitude, subjective norms, perception of behavioral control, perception of usefulness and trust. In contrast, online shopping intention is negatively affected by the perceived risks that online shopping could bring. Among those factors, the perception of risk is shown to have the strongest influence to online shopping intention. The findings of this study suggest that managers and retailers can apply cash-on-delivery method and design their website with user-friendly interface to enhance online shopping intention of consumers. The Government is also recommended to fulfill the law system to reduce customers' perception of financial risks.

BACKGROUND/OBJECTIVES: The purpose of this study was to examine the effects of knowledge about coronavirus disease 2019 (COVID-19), attitude, subjective norm, and perceived behavioral control on behavioral intentions to practice COVID-19 preventive behaviors using the theory of planned behavior (TPB). SUBJECTS/METHODS: A total of 519 restaurant customers' responses was collected in this study through an online self-administered questionnaire. Descriptive statistical analysis was performed on socio-demographic factors. One-way analysis of variance and t-test were conducted to determine differences in the constructs from the TPB according to age and sex. The hypotheses were tested using structural equation modeling (SEM). RESULTS: SEM revealed the positive effect of knowledge about COVID-19 on attitude, subjective norm, and perceived behavioral control to prevent the spread of COVID-19 in restaurants. Attitude, subjective norm, behavior intention, and knowledge positively affected COVID-19 preventive behavior intentions in restaurants. CONCLUSIONS: The results of this study confirmed that the TPB is helpful in elucidating the determinants of consumers' intention to practice COVID-19 preventive behavior in restaurants. These findings can help policy makers and professionals provide material for further public health interventions and inform them about awareness-raising, guidelines, and health education programs.

As the population is aging, accidents involving elderly people are also increasing (2014:11,667 persons; 2018: 11,797 persons). In the case of the elderly population, falling accidents are the primary direct or indirect causes of death; in particular, they face an elevated risk of staircase falls. This study proposes a method of evaluating the safety of staircases using Building Information Modeling (BIM)-based virtual simulation. By making a virtual user with the behavioral characteristics of the elderly respond to a staircase in a BIM model, its safety performance can be evaluated. The evaluation criteria were derived from regulations, elements, and characteristics relevant to the safety of staircases. To validate the proposed method, safety evaluation tests were simulated on actual staircases. The evaluation result of the test simulation shows the safety scores of 1.97 points for the elderly user and 2.95 points for the average male adult user against a required safety score of a minimum of 2 points. That is, safety is relative to users as the safety of the same staircase can be different depending upon the different behavioral characteristics of users. The study suggests that the risk of staircase-related fall accidents to the elderly can be reduced by improving staircase designs through the proposed method.

Purpose - Until recently, studies on customer values for restaurants recognized two path structures; the SERVQUAL model, that is, service quality? perceived value? customer satisfaction? behavioral intention, and the customer value? customer satisfaction? behavioral intention path that categorizes customer values into functional value and hedonic value. This study, instead, classifies the consumption values of fast-food restaurants based on the consumption value system provided by Sheth, Newman and Gross (1991) and illustrates the new path structure, consumption value? customer satisfaction? behavioral intention, targeting college students for a generalization of the consumption value system of fast-food restaurants. Research design, data, and methodology - This study establishes five hypotheses based on the relationship between each type of consumption value (functional, emotional, social, and epistemic) and customer satisfaction, and the relationship between customer satisfaction and behavioral intention. For this analysis, data was collected by conducting a pre-test and administering a survey to 213 college students who are regular customers at fast-food restaurants in Seoul, Korea. The data collected was then analyzed using SPSS 15.0 and AMOS 6.0 statistical packages. Results - The study showed that: First, the consumption values of fast-food restaurants are classified into the following four categories: functional value, emotional value, social value, and epistemic value while consumption value can be applied to customer value of fast-food restaurants. Second, the functional and epistemic values had a positive impact on customer satisfaction. The resulting satisfaction is attributed to the intrinsic characteristics of fast-food restaurants like the consistent quality of food, reasonable prices, fast service, and unique or new experiences on every visit. On the other hand, emotional and social values did not affect customer satisfaction. The results on emotional value differed from the general studies on restaurants while the results obtained for social value were not consistent with the studies on high-end restaurants. Third, customer satisfaction had a positive impact on behavioral intention. The survey showed that college students reflected behavioral intention - repurchase intention and word-of-mouth - if they were satisfied with the food quality and employee services provided. Simultaneously, it was seen that the impact of functional value on customer satisfaction of fast food restaurant goers was more than that of epistemic value. Conclusions - The consumption values of fast-food restaurant users could be classified into four categories, functional, emotional, social and epistemic values, based on the consumption value system provided by Sheth, Newman and Gross (1991). It proved that the customer values of restaurant goers can be extended to the path structure of consumption value? customer satisfaction? behavioral intention to confirm its generalization. The study also showed that marketing managers need to focus more on the factors that influence functional value as the fast-food restaurant users consider timely services with the consistent quality of food at a reasonable price and at a convenient place more important than the new experiences or uniqueness.
