The response behavior of a fish school to an approaching vessel was observed using scanning sonar. The evaluation using six parameters, which signify characteristics of school shape and behavior by sonar image processing, was proposed. Ten fish schools were analyzed and among them, three fish schools were identified for their changing shape, swimming direction, and swimming speed. Moreover, by tracing fish schools on stack of sonar images, these fish schools were seen to exhibit an apparent change of school shape and behavior. Therefore, the evaluation method of fish school behavior using six characteristic parameters indicating fish school shape and behavior by sonar image processing is useful.

Purpose: This study aimed to identify the actor and partner effects of self-efficacy, marital adjustment, and social support on the health promoting behavior of Korean pregnant couples. Methods: Participants were 132 couples who met the eligibility criteria. Data were collected from June to November, 2016 at a community health center. The Actor-Partner Interdependence Model was used for analyzing the actor and partner effects of self-efficacy, marital adjustment, and social support on health promoting behavior. Results: The fitness indices for the model were GFI=0.90, NFI=0.92, CFI=0.91, TLI=0.90, and RMSEA=0.04, which satisfied the criteria. Self-efficacy had actor and partner effect on health promoting behavior of wives, but had only actor effect of on health promoting behavior of husbands. Marital adjustment showed actor and partner effect on the health promoting behavior of pregnant couples. Social support only had an actor effect on the health promoting behavior of wives. And, marital adjustment and social support had a mutual effect. Conclusion: This study indicates that the partner involvement is needed to develop health promotion programs for pregnant couples.

The purpose of this study was to examine the relationships of mothers exhibiting maternal overprotective behavior and their children's aggression, withdrawal and perceived competence. For data collecting, 339 children attending the fifth/sixth grade of elementary school in Kwangju were involved. The major findings were as follows: First, maternal overprotective behavior related to school learning showed a significant difference due to the children's sex. Furthermore, maternal overprotective behavior related to daily life and school learning showed a significant difference due to the children's grade. Second, maternal overprotective behavior related to daily life showed a significant difference due to the mother's education level. Finally, the result of multiple regression analysis on the effects of the mother's overprotective behavior to the children's aggression, withdrawal, and perceived competence indicated that maternal overprotective behavior related to daily life and school learning was the significant contributing factor. All in all, the variables accounted for 11% of the children's aggression, 11% of the children's withdrawal, and 6% of the children's perceived competence.

The purpose of this study was to analyze the role of perceived market influence, which is an important psychological factor influencing consumer behavior in the market, and explain how consumer beliefs related to the market can affect sustainable consumer behavior. First, this study found that gaps in perceived market influence were statistically significant for age and job. Second, environmental concern, organic food consumption (vegetables and meats), and purchase behavior of organic foods were found to be significantly different by degree of perceived market influence of consumers. The mean values were found to be high for the group having strong perceived market influence. This tendency suggests an association between higher perceived market influence consumers and more environmentally friendly consumer behavior. Lastly, this study used Structural Equation Modeling to analyze the effect of perceived market influence as a moderating variable and mediating variable on the relationship between environmental concerns and consumer behavior toward organic foods. The results show a mediating effect on perceived market influence, but a moderating effect could not be found. This result implies that perceived market influence might indirectly affect consumer behavior when transferring environmental concerns to consumer behavior toward organic foods.

The effects of Eurycoma longifolia Jack were studied in maintaining mating behavior of sexually experienced castrated male rats after dosing them with 500 mg/kg daily of E. longifolia Jack for 10 days prior to test and later continued for two weeks where the rats were then castrated. The similar dosage was then continued for 12 weeks post-castration. However, $400\;{\mu}g/day$ of testosterone was administered subcutaneously on the day of castration and lasted for 6 weeks post-castration but later raised to $800\;{\mu}g/day$ until 12 week post-castration. Tests were conducted weekly from 2-6 weeks and 8-12 weeks post-castration. Results showed that all the experimental male rats exhibited mating behavior before castration. Further results also indicated that E. longifolia Jack successfully maintained mating behavior but less than precastration level from 2-6 weeks and later increased from 8-12 weeks post-castration. Similarly, $400\;{\mu}g/day$ of testosterone was effective in maintaining mating behavior from 2-6 weeks post-castration. However, $800\;{\mu}g/day$ of testosterone managed to return the male rats to the precastration level with all male rats exhibited mating behavior from 8-12 weeks post-castration. Further results also indicated that testosterone significantly increased the penis weights (p < 0.05) as compared to the E. longifolia Jack. In conclusion, this study shows that E. longifolia Jack continued to maintain mating behavior of sexually experienced castrated male rats, giving further evidence of the folkuse of this plant as aphrodisiac.

Purpose: This study aimed to investigate the influence of uncertainty-related factors on the health behavior of individuals with coronary artery disease (CAD) based on Mishel's uncertainty in illness theory (UIT). Methods: We conducted a cross-sectional study and path analysis to investigate uncertainty and factors related to health behavior. The study participants were 228 CAD patients who visited the outpatient cardiology department between September 2020 and June 2021. We used SPSS 25.0 and AMOS 25.0 software to analyze the data. Results: The final model demonstrated a good fit with the data. Eleven of the twelve paths were significant. Uncertainty positively affected danger and negatively affected self-efficacy and opportunity. Danger had a positive effect on perceived risk. Opportunity positively affected social support, self-efficacy, perceived benefit and intention, whereas it negatively affected perceived risk. Social support, self-efficacy, perceived benefit and intention had a positive effect on health behavior. We found that perceived benefit and intention had the most significant direct effects, whereas self-efficacy indirectly affected the relationship between uncertainty and health behavior. Conclusion: The path model is suitable for predicting the health behavior of CAD patients who experience uncertainty. When patients experience uncertainty, interventions to increase their self-efficacy are required first. Additionally, we need to develop programs that quickly shift to appraisal uncertainty as an opportunity, increase perceived benefits of health behavior, and improve intentions.

This study is a descriptive survey research conducted to confirm the effects of work values and career adaptability on job preparation behavior in Graduation year nursing students. The subjects are 4th grade students who are attending two university nursing departments in city G and N, and data were collected from September to October 2023. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation analysis and controlled regression analysis. The research results are as follows. Intrinsic values (β=-.127, p=.122) had not statistically a significant effect on job preparation behavior. Extrinsic values (β=.168, p<.001) and career adaptability (β=.415, p<.001) had statistically a significant positive effect on job preparation behavior. The variables predicting the job preparation behavior of nursing students were identified in the order of career adaptability and extrinsic values. The study model accounted for 35.5% of job preparation behavior. It suggests that strategies are needed to enhance the extrinsic values and career adaptability in order to promote job preparation behavior in nursing students. However, considering the nature of nursing and the sense of calling of nurses who perform nursing, we should not overlook the fact that the intrinsic values of nursing itself is also an important aspect that nursing students preparing to become future nurses must cultivate.

Participants in real-time online sessions, be it (business) meetings, virtual school lessons, or social live streams, all engage in cyber social interactions. Unlike parasocial interactions, cyber social interactions are characterized by reciprocity and temporal proximity. In contrast to social interactions, they lack spatial proximity and bodily contact. This is a fairly new concept in information science that rose from technological advances and unprecedented circumstances (e.g., the rise of digital economy and knowledge workers being able to work remotely or, more recently, global lockdowns and contact restrictions). As a result, the past ways of working and socializing were transformed by making them, in some cases predominantly, virtual. Regarding the example of social live streaming we exhibit the importance of cyber social interactions for information behavior research. This conceptual article is a plea for information science to engage more in human-human online relations and interactions.

Background: Career success is the psychological achievement associated with an individual's work. Protean career management behavior is the behavior of managing individual careers in order to achieve individual career goals. The purpose of this study was to clarify the career success of dental hygienists as perceived by clinical dental hygienists and to compare the relationship between career success and protean career management behavior. Methods: Nationwide convenience samples of clinical dental hygienists were obtained; 354 people were surveyed online, and the data of 350 people were finally analyzed. The perception of career success of dental hygienists was assessed using a multiple response method. T-test, ANOVA, and χ2 tests were performed to investigate the differences and relationships between protean career management behavior and career success according to the general characteristics. Results: Career success was recognized by clinical dental hygienists as "income", "work proficiency", "patient consultation", "self-satisfaction", and "recognition by superiors" in order. There were significant differences in protean career management behavior according to general characteristics (p<0.05). Higher career management behavior was common in those higher in age, in married participants, in those with higher educational background, and in those with a higher career, better position, and more job change experience (p<0.05). Among the variables of career success perceived by clinical dental hygienists, "work proficiency" had a significant effect on "career management behavior" (p<0.05). "Work proficiency" and "recognition by superiors" were significant in "protean technological development behavior," and they also influenced actual behavior (p<0.05). Conclusion: The relationship between dental hygienists' career success and protean career management behavior was clarified. Dental hygienists performed career management behaviors to develop work ability and skills. In addition, the relationship between career management behavior and long-term employment was confirmed.
