BACKGROUND/OBJECTIVES: With the advances in technologies, self-service kiosks at foodservice operations are becoming a new way of service provision. This study examined the relationships among the menu information quality, nutrition information quality, technology acceptance characteristics, and customer behavioral intention toward the kiosks in fast food restaurants. SUBJECTS/METHODS: A survey with a self-administered method was distributed online and offline. The sample consisted of customers who had used the kiosks at fast food restaurants in the last six months prior to the survey. The study hypotheses were tested by applying structural equation modeling. RESULTS: Structural equation modeling revealed the positive impacts of menu information quality and nutrition information quality, technology acceptance characteristics, and behavioral intention toward kiosks at fast food restaurants. On the other hand, one hypothesis (Hypothesis 4) on the impact of nutrition information quality on the perceived usefulness was rejected. CONCLUSION: The study is the first to investigate nutrition and menu information at foodservice kiosks and relate them to technology acceptance. The study is very timely and adequate in the time of the 4^th industrial revolution. The critical importance of the presentation of nutrition information and menu information at the kiosks at fast food restaurants was verified. The academic and industrial implications of the study findings were discussed.

The Namdae stream in Gangneung-si is one of the rivers where salmon stock is mainly maintained by natural spawning rather than artificial seedlings. There are structures including weir, and fish distribution and movement characteristics can be different by these structures. In this study, we investigated the distribution and behavioral characteristics of salmon by sighting survey within 12 km immediately upstream of the river mouth between October 2021 and February 2022. As a result, salmon distributed within 9 km from rivermouth. There were more salmon in the lower reaches of Doosan weir than in the upper reaches of that. The main spawning ground for salmon was between 7-9 km from rivermouth and around the lower part of Doosan weir. Salmon behaved for spawning in the gravel-bed area and undercut slope of the mainstream, such as mating, digging the riverbed, and competition among males. Salmon moved more slowly in the gravel-bed area than sand-bed area. Doosan weir hinders the spawning migration of salmon by frequent flow changes and terraced fishway. This study provides primary information to understand the ecological changes of salmon by environmental changes in the Namdae stream.

Capture efficiencies of commercial shrimp trawls may improve if their designs took into better account behavioral responses of wild shrimp to approaching cod-end of the trawls. Here we report results of water tunnel-based experimental studies of responses of wild California target prawns to several different near-realistic netting configurations over a range of water velocities (0.3-0.7 m/s). Netting panels were oriented at parallel to water flows (FP) on the bottom of test section, vertical (VT) or diagonal sloping backward (DG), bottom to top. Behavioral responses were recorded by video camera and analyzed frame by frame. Measured responses included rates of penetrating through netting by behavioral features and tail-flip frequencies. Frequencies of prawn passing through the nets increased with flow speed for both orientations and were higher at given speeds for sloped nets. Other behavioral features (e.g., passage head-or tail-first) also varied significantly with water velocities and netting orientation. Interactions of penetrating rates between netting orientations and flow speeds also were significantly dependent, except for prawn size. Additional studies are needed of other shrimp species and at higher water velocities more similar to actual field operations using trawls to improve size selectivity.

The current study examined the effects of socio-demographic characteristics and peer relations on the emotional, behavioral, and comorbid disorder symptoms among low-low-SES children, using the Young Lives Survey: an International Study of Childhood Poverty: Round 1, 2002. Participants were 1,000 8-year-old children (502 boys and 498 girls) from low-low-SES families. Data were analyzed using ANOVA, t-tests, post hoc test (Scheffe's method), correlations, and multiple logistic regression analyses according to the analysis strategy. There was a moderate correlation between selected socio-demographic variables and emotional/behavioral disorder symptoms, and the caregiver's marital status, child's health compared to others, child's work status corresponded to significant differences in their emotional/behavior levels. Regarding the logistic regression analysis, in addition to the effects of socio-demographic variables reflecting the characteristics of less-developed countries, marital status, child's working status, and conflicts with peers proved to be detrimental to emotional, behavioral, or comorbid disorder symptoms in low-SES children, who have been lack quality parenting, social resources, and child human rights. Results indicated the need to develop health care services that would address those problems and appropriate intervention and prevention programs targeting children in low-income families. Moreover, careful assessment and intervention for child's health status, child's working status and peer relationship problems are suggested as possible strategies for helping children at risk of exhibiting further problematic behaviors.

This study views the people's propensity to rely on others' evaluations as the interpersonal trust online despite a lack of personal interactions. Therefore, this study explores the underlying dimensions of interpersonal trust and examines how interpersonal trust influences trust in the e-tailer and behavioral intent. Data of 395 adults who had purchased apparel goods online were collected nationwide using an online questionnaire. Exploratory and confirmative factor analysis identified five underlying constructs of interpersonal trust online such as peer identification, ability, integrity, shared lifegoals, and benevolence. A structural equation modeling test was conducted to examine the relationships between interpersonal trust, trust in the e-tailer, and behavioral intent. Interpersonal trust influenced on trust in the e-tailer, specifically on trust in the e-tailer's competence which subsequently increased a customer's behavioral intent such as attitude toward the e-tailer and shopping intention. Although no direct effect of interpersonal trust on the behavioral intent was found, interestingly, the effects of the interpersonal trust on the e-tailer trust which derived the behavioral intent to purchase. This result suggests that marketers devise a more effective system and environment that can encourage the interpersonal trust between customers to build a strong trust in e-tailers. It also provides a theoretical framework of online trust in the way of classifying interpersonal trust and trust in e-tailers.

Black-billed magpies (Pica pica) are a highly sedentary species due to their short and round wings, which are not adequate for long distance flights. We investigated geographic variation in the vocal signals of magpies residing in South Korea and Japan (subspecies sericea). Based on the magpie's limited dispersal ability, we predicted that the variation in vocal signals of black-billed magpies could be explained by geographic barriers such as mountain ranges and straits. We analyzed four-syllable chatter calls of magpies from five localities in South Korea, which are separated by mountain ranges (Seoul, Daejeon, Daegu, Gwangju, and Busan), and two island localities separated from the mainland by straits (Jeju in Korea and Saga in Japan). We found significant differences in the characteristics of magpie chatter calls recorded in the seven localities, and the variation pattern was independent among the variables. Mainland-island differentiation and north-south differentiation were observed. In general, magpies on Saga were the most distinctive. North-south differentiation was observed among the Korean mainland localities. However, the pattern was not related to the presence of putative geographic barriers. We hypothesize that the patterns of geographic variation in the structure of magpie chatter calls residing in South Korea might have been shaped by a sudden expansion of magpies followed by low level of local isolation, which may have led to vocal differentiation. Along with elucidating the vocal environment of Korean magpie populations, more extensive sampling is needed to clarify the functional aspects of geographic variation in the vocal signals of Korean magpies.

This research investigates the mechanism of ethical fashion consumption by examining the effects of benefit and risk perception on ethical fashion consumption attitudes and behavioral intention. To test the hypotheses, 300 female consumers between the ages of 20 and 49 were invited as study participants. The reliability and the validity of multi-item constructs were tested by Confirmatory Factor Analysis. The hypotheses were tested by utilizing Structural Equation Analysis and hierarchical multiple regression analysis. The benefit perception of ethical consumption was composed of three benefit types, which were altruistic benefit, social image benefit, and self-oriented benefit. Benefit perception, except social image benefit, had significant effects on consumer attitudes towards ethical fashion consumption; similarly, benefit perception had significant effects on behavioral intention (except self-oriented benefit) which had an effect on behavioral intention only when it was mediated by attitudes. Further analysis was conducted to understand the reason for the weak relationship between attitudes and behavioral intention. Financial and performance risk perceptions were tested for the moderating roles of attitudes and behavioral intention; subsequently, only financial risk interacted with attitudes and showed that the positive effects of attitudes on behavioral intention were weakened by a high financial risk perception. Performance risk had a main effect on behavioral intention independent of attitudes. Managerial implication and future study directions are also discussed.

The purpose of this study was to determine the effects of the father's experiences from his family-of-origin, marital conflict, and childrearing behaviors on his child's behavioral problems, as well as any differences due to the child's sex. The subjects were 837 days of 4th and 5th graders in six elementary schools and their fathers in Seoul and Pusan. The data were analyzed using the Structural Equation Modeling(SEM) to verify the theoretical models among the variables. The results showed that the pathways of the impact of the father's experiences from his family-of-origin differed, depending on the father-son group and the father-daughter group, upon the child's intermailizing and extenalizing behavioral problems through marital conflict and the father's childrearing behaviors. Firstly, in the father-son model, the father's experiences from his family-of-origin had an impact on the son's internalizing and extenalizing behavioral problems through marital conflict and the his negative childrearing behaviors. Secondly, the father-daughter model exhibited two pathways; the father's experiences from his family-of-origin had an impact on the child's internalizing and externalizing behavioral problems through his negative chilrearing behaviors, and the father's experiences from family-of-origin had an impact on the child's internalizing behavioral problems through marital conflict and his positive childrearing.

This study explored the conceptual constructs of shopping values and experiential marketing components of home furnishing brands as well as their impacts on the behavioral intention toward home furnishing goods. The mediating roles of experiential marketing were investigated in this research. A survey was performed on female shoppers between the ages of 20 and 50 who have visited and shopped at home furnishing brand stores. The results of this research were as follows. 1) The results to analyze the sub-dimension of shopping values (Social, Differential, Utilitarian, Aesthetic, Entertaining, and Sustainable) and experiential marketing components (Sense, Emotion, Coordination information, and Customer services) showed factorial structures. 2) Aesthetic, Differential, and Utilitarian shopping values showed significantly positive influences on behavioral intentions of home furnishing brand products; in addition, Sense, Emotion, and Coordination information components of experiential marketing had a positive effect on behavioral intentions of home furnishing brand products. 3) The Emotion and Sense components of experiential marketing had important medicating roles in the relationship between shopping values and behavioral intentions of home furnishing brand products. This study highlighted that shopping values and experiential marketing components should be promoted among consumers to increase behavioral intentions of home furnishing brand products.
