The purpose of this study is to examine the prevalence of depression in Korean American men and factors associated with the Korean American men's depression by examining how depression is affected by socio-demographic characteristics, immigration-related characteristics, and psychological and social characteristics. Socio-demographic characteristics include age, education, occupation, and monthly income. Immigration-related characteristics include years in the U. S., being U. S. citizens, and acculturation level. Psychological and social characteristics include anger, marital satisfaction, and social support. Using an availability sampling method, data were collected from 201 Korean American married men who were between the ages of 20 and 64 and resided in Los Angeles County. This study used a structured self-administered questionnaire. Due to the unreliable responses, five questionnaires were excluded from the study. Therefore 196 completed questionnaires were used for the data analyses. In order to measure the respondents' depression, the CES-D(Center for Epidemiological Studies of Depression) was used in this study. In the hierarchical multiple regression analyses, monthly income, anger, marital satisfaction, and social support were significantly associated with the respondents' depression. However, there were no significant associations between depression and age, education, occupation, being a U. S. citizen, and acculturation. Implications of the findings for mental health practitioners and social works are discussed.

This study conducted an empirical analysis of the factors affecting the job commitment of employees within a financial sales organization, focusing particularly on agile leadership and organizational justice. Agile leadership was subdivided into four components: adaptability, collaboration promotion, proficiency, and an agile approach, whereas organizational justice was broken down into distributive justice, procedural justice, and interactional justice. Data were gathered through an online survey, and 245 valid responses were subjected to hierarchical regression analysis. The results revealed a significant positive effect of distributive justice, interactional justice, adaptability, promotion of collaboration, and an agile approach on job commitment among the employees of the financial sales organization. However, the influence of proficiency, a component of agile leadership, and procedural justice, a dimension of organizational justice, did not prove to be statistically significant. The order of influence among the significant variables was found to be: adaptability, interactional justice, promotion of collaboration, distributive justice, and an agile approach. These findings confirmed the impact of agile leadership in financial sales organizations, traditionally viewed as conservative, and suggested practical implications for the financial sector to adapt in anticipation of the Fourth Industrial Revolution.

In a recent study conducted in South Korea, a nation grappling with the implications of an increasingly super-aged society, researchers empirically analyzed the factors influencing seniors' satisfaction with financial institutions' wealth management (WM) services. We surveyed 250 seniors who utilized financial institutions' wealth management services. Independent variables such as product(diversity, profitability, stability), employee(expertise, problem-solving ability, customer orientation), physical evidence, process, inheritance service, and trust service were carefully examined. Employing hierarchical regression analysis, we tested hypotheses within an established research model. The findings revealed that variables like product stability and profitability, employee problem-solving ability, customer orientation, process, inheritance service, and trust service significantly positively affected satisfaction with WM services. In contrast, no substantial association was detected between satisfaction and factors like product diversity, employee expertise, or physical evidence. Among the influential factors, the order of impact was determined to be employee customer orientation, problem-solving ability, trust service, product stability, inheritance service, product profitability, and process. This research provided essential insights into the nuanced preferences and needs of seniors concerning wealth management services. The detailed examination of the subject might also shed light on similar challenges faced in the other aging societies. As the global population continues to age, the implications of this study could reach far beyond the borders of South Korea. By understanding these key determinants of satisfaction, financial institutions worldwide can tailor their wealth management services to better meet the unique demands of the senior population.

Recently, the aging of SME managers has emerged as a major issue in business succession. The smooth succession of small and medium-sized enterprises (SMEs), which are the industrial base of Korea, is becoming an important issue for enhancing the vitality of the national economy, such as job creation, beyond mere discussion of inheritance. At this point, this study conducted an empirical analysis on the factors affecting corporate succession intention. As independent variables, corporate Capability consisting of employee competency, marketing competency, and digital competency, human factors such as managers, successors, and third-party stakeholders, and institutional factors such as legislation, taxation, and trust were set. In addition, the effect of adjusting the sales scale was verified. To this end, a survey was conducted targeting representatives who are currently running small and medium-sized enterprises (SMEs). The total number of valid questionnaires was 315. Based on this, an empirical analysis was conducted using the hierarchical regression method. The results of the empirical analysis are as follows. First, marketing competency and digital competency, managerial competency and successor competency, taxation and trust had a significant positive (+) effect on corporate succession intention. However, a significant influence relationship between the third stakeholder, employee competency, and corporate succession intention was not tested. Among the factors that have a significant impact, the size of the influence was in the order of taxation, successor competency, executive competency, trust, marketing competency, and digital competency. Second, the size of sales was found to moderate the relationship between the variables that had a significant effect on corporate succession intention, that is, management competency, successor competency, marketing competency, digital competency, taxation and trust, and corporate succession intention. Based on these research results, academic, practical, and institutional implications for smooth business succession are presented.

This study was conducted to empirically analyze the impact of issue leadership and learning agility on the innovation behavior of startup employees. Issue leadership was subdivided into issue creation, audience engagement, and issue execution. Learning agility was subdivided into five factors: feedback seeking, information orientation, reflection, experimentation, and agility. The survey was conducted among employees working in startups. In this study, 300 valid surveys were analyzed. Hierarchical regression was used to test the hypotheses. The results of the empirical analysis were as follows Among the sub-factors of issue leadership, issue creation, audience engagement, and the sub-factors of learning agility, information orientation, reflection, experimentation, and agility had a significant positive effect on startup employees' innovation behavior. On the other hand, issue execution, a subcomponent of issue leadership, and feedback seeking, a subcomponent of learning agility, did not have a significant effect on innovative behavior. In addition, the magnitude of the effect on innovative behavior was in the order of experimentation, agility, issue creation, information orientation, audience engagement, and reflection. Therefore, this study on the effect of issue leadership and learning agility on innovative behavior concludes that issue creation, audience engagement, information orientation, reflection, experimentation, and agility play an important role.

Seed color is controlled by several genes and is a key trait in determining the metabolite content and biological activities of legume genotypes. In this study, 296 adzuki bean accessions, including 159 grey, 99 red, and 38 white adzuki beans, were grown in Korea. Variations in total phenolic content (TPC), total saponin content (TSC), DPPH^• scavenging activity, ABTS^•+ scavenging activity, and ferric reducing antioxidant power (FRAP) were assessed and were reported to be in the ranges of 1.52-8.24 mg GAE/g, 14.36-114.22 mg DE/g, 0.23-12.84 mg AAE/g, 1.05-17.66 mg TE/g, and 0.59-13.14 mg AAE/g, respectively, with a wide variation across adzuki beans. Except for DPPH^• scavenging activity, the average values declined in the order gray > red > white adzuki beans, each demonstrating a significant variation (p < 0.05). White adzuki beans, which showed low metabolite content and antioxidant activity, were clearly separated from the gray and red genotypes using principal component and hierarchical cluster analyses. Moreover, TPC, TSC, and antioxidant activities were strongly correlated, regardless of seed color. Overall, the diversity of the TPC, TSC, and antioxidant activity in a broad population of adzuki bean genotypes was determined. Furthermore, this study found that seed color variation in adzuki beans had a significant effect on the metabolite content and antioxidant activity. Superior accessions with high levels of TPC, TSC, and antioxidant activity were also discovered and could be used for functional plant breeding and human consumption. The findings of this study may be useful for understanding the relationship between seed coat color and metabolite concentration in adzuki beans, paving the way for molecular-level analyses.

Since there are differences in the content, structure and functions of interpersonal communication during the practice of school science classes, it needs to articulate the difference of the modality of pedagogical practice in order to understand science teaching in detail. These characteristics of science teaching can be investigated by further insightful analysis on language in the science classroom. In this study, classroom discourse language codes using Bernstein's code theory were analyzed in the case of a middle school science class on the unit of minerals. The discourse language code was identified by the value of classification, which revealed power relations to the contexts of discourse and participants of discourse. It was also identified by the value of framing, which showed hierarchical relation between teacher and students as discourse subjects, and discursive control on the initiative of discourse. The results addressed that six types of discourse language codes were constructed and that those language codes reflected diverse modalities of science teaching from student-centered instruction to teacher-centered instruction in relation to classroom discourse. The modality of science teaching according to the transition tendencies of discourse language code showed dynamic variations of 'controlled student-centeredness inducing teaching' - 'positional student-centeredness permissive teaching' - 'controlled students' participation permissive teaching' - 'controlled student-centeredness facilitative teaching' - 'student-centeredness enhancing teaching'. In addition, results released that discursively and hierarchically weak control of discourse is necessary for enhancing student-centeredness of science teaching. Moreover, teaching practice enhancing student-centeredness can be accomplished by the harmony of a teacher's perception of discourse language code and his/her orientation to constructivist teaching and student-centered teaching.

Purpose : In this study, we aimed to determine the impact of the COVID-19 pandemic on nursing students' adjustment to college life by focusing on their empathic ability, perceived stress, and resilience. Methods : We applied a descriptive survey research design, which included a self-report questionnaire. The participants comprised 307 nursing students in B city. The data were analyzed by calculating the percentages, means, standard deviations, t-tests, ANOVA, Scheffé test, Pearson's correlation coefficients, and hierarchical regression using SPSS 23.0. Results : The participants' empathic ability score was 3.30±.42, perceived stress score 1.85±.49, resilience score 3.44±.64, and adjustment to college life score 3.25±.52. Adjustment to college life was positively correlated with resilience (r=.43, p<.001) but negatively correlated with perceived stress (r=.27, p<.001). Factors affecting adjustment to college life include, among general characteristics in Model 1, in descending order, major satisfaction-satisfied (β=.54, p<.001), interpersonal conflict: never (β=.26, p=.018), health status: healthy (β=.25, p=.002), character: positive (β=.21, p=.006), character: optimistic (β=.19, p=.015), parents' economic power: high (β=.15, p=.047), and gender: male (β=.11, p=.016). Model 1 was statistically significant (F=11.67, p<.001), and the explanatory power was 41 %. In Model 2, empathic ability, perceived stress, and resilience were added as independent variables. When including the dependent variables, the factors that most influenced adjustment to college life were perceived stress (β=-.37, p<.001), major satisfaction-satisfied (β=.36, p<.001), health status-healthy (β=.25, p<.001), gender-male (β=.10, p=.015), and resilience (β=.10, p=.029). Model 2 was statistically significant (F=17.65, p<.001), and the explanatory power was 56 %. Conclusion : We found that gender, major satisfaction, health status, perceived stress, and resilience affected adjustment to college life among nursing students who had experienced the COVID-19 pandemic. To increase their ability to adjust to college life, a gender-specific intervention program should be developed that can improve the students' health status, major satisfaction and resilience, and reduce their perceived stress.

This study was conducted to examine the self-efficacy and rejection sensitivity of nursing college students and their college life adjustment, as well as to identify the impact of self-efficacy and rejection sensitivity on college life adjustment. An online survey via URL was conducted on 154 enrolled students from nursing colleges nationwide. The collected data were analyzed using SPSS/WIN 23.0 statistical software for descriptive statistics, independent t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression analysis. The results of the study showed that the self-efficacy of the subjects was 3.80±0.63 points, rejection sensitivity was 2.67±0.83 points, and college life adjustment was 3.58±0.54 points. The factor influencing the college life adjustment among nursing college students was self-efficacy (β=.42, p<.001), while rejection sensitivity showed a significant negative correlation with adaptation to university life (r=-0.24, p=.003), but it was not a significant influencing factor. Therefore, it is necessary to develop and utilize various teaching methods and programs for psychological and social support to enhance self-efficacy in order to improve the adjustment of nursing college students to college life.

Purpose: The purpose of the study was to conduct a descriptive survey to examine the knowledge, infection prevention behaviors, and health beliefs regarding COVID-19 and to identify factors that influence infection prevention behaviors in elementary and middle school students based on the Health Belief Model. Methods: The study included 388 elementary and middle school students in Seoul, Gyeonggi, and Jeonbuk provinces. Data were collected from September 1 to September 15, 2023. The questionnaire consisted of 10 questions about COVID-19 knowledge, 13 questions about infection prevention behaviors, and 15 questions about health beliefs. The collected data were subjected to multiple hierarchical regression analyses. The cronbach's α of infection prevention behaviors was 0.83, the KR-20 of COVID-19 related knowledge was 0.68, and the Cronbach's α of COVID-19 related health beliefs was 0. 78. Results: In Model 1, females showed higher levels of infection prevention behaviors than males (β=.14, p=.006) and middle school students showed lower levels of infection prevention behaviors than elementary school students (β=-.10, p=.037). In Model 2, among COVID-19-related health beliefs, barriers had a significant negative effect on infection prevention behaviors (β=-.20, p<.001) and cues to action had a significant positive effect on infection prevention behaviors (β=.14, p=.037), indicating that lower barriers and higher cues to action were associated with higher levels of infection prevention behaviors. Conclusion: The results showed that prevention behaviors were associated with lower barriers and higher cues to action among COVID-19 health beliefs. Elementary and middle school students in Korea spend a lot of time in groups at private academies or school, which are closed spaces with poor ventilation, making them vulnerable to new infectious diseases such as COVID-19. Unlike adults, infectious diseases can have serious impact on their mental and social health. Therefore, it is necessary for schools to provide accurate and timely health education about COVID-19 to increase cues to action for elementary and middle school students in order to improve their infection prevention behaviors.
