We use a time-varying parameter vector auto regression (TVP-VAR) model to understand the impact of U.S. monetary policy normalization on Korean financial markets and capital accounts. The U.S. monetary policy is represented by the federal funds rate, term premium and credit spread. During the U.S. monetary contraction period of 2004 to 2006, changes in the federal funds rate presented negative pressure on Korean financial markets. The changes in federal funds rate also led to a simultaneous contraction in inward and outward capital flows. However, the effects of a federal funds rate shock has been reduced since 2015. On the other hand, the effects of U.S. term premiums is getting stronger after the period of quantitative easing (QE). The influence of the U.S. credit spread also significantly increased after the global financial crisis. Simulation results show that a rise in the U.S. credit spread, which can be triggered by a contractionary monetary policy, can pose a larger adverse impact on the Korean economy than a rise in the federal funds rate itself. As for capital flows, a U.S. monetary policy contraction causes an outflow of foreign investment, but the repatriation of overseas investment by Korean residents can offset this outflow.

This study investigated effects of Korean students' contacts with International students on Korean college students' multicultural competencies. This study also examined mediating effects of life satisfaction and realistic conflict perception between contacts with international students and multicultural competencies. For the purpose, 384 Korean college students completed the questionnaires including contacts, life satisfaction, realistic conflicts perception toward international students, everyday multicultural competencies, and demographic information. The results indicate that number of contacts predicts cultural self-efficacy and cultural knowledge, whereas contact diversity predicts cultural openness. Life Satisfaction predicts cultural openness, cultural self-efficacy, and cultural knowledge, and realistic conflicts perception predicts all subscales of everyday multicultural competencies scale other than cultural knowledge. Results also discovered that life satisfaction mediates the relationship between contact diversity and multicultural competencies, but realistic conflict perception did not mediate between contact diversity and multicultural competencies. Based on the results, the suggestions to enhance college students' multicultural competencies were discussed.

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.

The purpose of this study is to investigate the relation among alcohol outcome expectancies, alcohol abstinence self-efficacy, perceived drinking norms and alcohol use. This study was conducted via e-mail. Among 392 students who were participated via E-mail, 300 students (male 148, female 152) were met a definition of Wechsler's binge drinking. The results revealed that perceived norms were associated with alcohol use in binge drinking group, while those were not in non-binge drinking group. It was identified that a difference of peer's actual alcohol consumption and peer's perceived drinking was associated with individual alcohol use. Moreover, for binge drinking group, perceived norms predicted alcohol use better than any other factors. Drinking motives mediated the relation with perceived norms and alcohol use. Especially perceived norms affected alcohol use not only by increasing drinking motives but also by itself. Implication of this study is to provide a basis of prevention and intervention of binge drinking for college students.

This study analyzes the dynamic characteristics of cargo volume (demand), ship fleet (supply), and freight rate (price) of container, dry bulk, and tanker shipping markets by using the VAR and VECM models. This analysis is expected to enhance the statistical understanding of market dynamics, which is perceived by the actual experiences of market participants. The common statistical patterns, which are all shown in the three shipping markets, are as follows: 1) The Granger-causality test reveals that the past increase of fleet variable induces the present decrease of freight rate variable. 2) The impulse-response analysis shows that cargo shock increases the freight rate but fleet shock decreases the freight rate. 3) Among the three cargo, fleet, and freight rate shocks, the freight rate shock is overwhelmingly largest. 4) The comparison of adjR² reveals that the fleet variable is most explained by the endogenous variables, i.e., cargo, fleet, and freight rate in each of shipping markets. 5) The estimation of co-integrating vectors shows that the increase of cargo increases the freight rate but the increase of fleet decreases the freight rate. 6) The estimation of adjustment speed demonstrates that the past-period positive deviation from the long-run equilibrium freight rate induces the decrease of present freight rate.

사회적 기업가정신은 기업가정신 분야의 연구에서 많은 학자와 산업계의 관심을 받고 있는 주제이다. 특히 사회적 기업을 창업하거나 사회적 기업에서 일하고자 하는 사람들은 일반 사람들과 다른 어떤 특성을 가지고 있는지에 대해 선행 연구들은 공감, 도덕적 판단, 지각된 사회적 규범 등의 요소들로 설명하고 있다. 이는 전통적인 기업의 창업자와 비교되며, 사회적 기업가정신에 중요한 선행요소라고 말하고 있다. 그러나 공감능력이 뛰어나고, 공동체에서 사람들과 잘 어울리며, 남을 돕기 좋아하는 사람들이 반드시 사회적 기업가적 의도가 높은 것은 아니며, 이런 특성을 가진 모든 사람들이 사회적 기업에서 일하고자 하는 것은 아니다. 사회적 기업가적 동기에 관한 선행 연구 중에 동기와 행동을 연결하는 복잡한 매커니즘에 대해 설명한 연구는 거의 없는 상황이며, 대부분 공감(Empathy), 사회적 자기 효능감(Social Entrepreneurial Self-Efficacy), 도덕적 의무감 등의 요소를 규명하는데 집중되어 왔다는 한계가 있다. 본 연구는 지금까지 거의 연구되지 않았던 사회적 기업적 의도를 설명하는 타인 지향적 동기(other-oriented motives)와 사회적 기업 직업정체성에 관한 연구이다. 이를 통해 사회적 기업에 참여하려는 개인의 성향을 촉진시키는 요인은 무엇인지를 규명하고자 하였다. 전국 일반고, 특수목적고 및 특성화고등학교와 대안학교 학생 444명을 대상으로 설문조사를 실시하여 타인 지향적 동기요소인 친사회성 동기, 사회적 존재감과 사회적 기업 직업정체성의 관계 분석에 활용하였다. SPSS 26 버전을 활용하여 다중 회귀분석을 실시한 결과 사회적 기업에 대한 직업정체성에 친사회적 동기와 사회적 존재감은 긍정적인 영향을 미치고, 특히 사회적 존재감은 친사회적 동기와 직업정체성과의 관계에 부분 매개효과를 보였다. 결과적으로 역지사지 성향을 가지는 학생일수록 사회적 기업에서 일을 할 의도가 높아지고, 남을 돕고자 하는 의지가 높은 학생, 공동체 의식이 높은 학생일수록 사회적 기업에서 일을 하고자 하는 의지가 높다는 것을 알 수 있었다. 또한 사회적 존재감은 이 과정에서 간접적으로 유의미하게 긍정적인 영향을 미치는 것을 알 수 있었다. 본 연구는 사회적 기업에 대한 직업정체성에 영향을 미치는 선행요인을 규명하고 사회적 기업에 참여하려는 개인의 성향을 촉진하는 요인이 무엇인지 규명했다는 데 의의가 있다. 그리고 이 요인들이 교육을 통해 강화할 수 있으므로 사회적 기업 창업가 육성에 대한 새로운 방향을 제시한다.

Purpose: This study examined the factors affecting sugar intake in adults based on social cognitive theory. Methods: An online survey regarding the intake frequency of sugar-source food, factors related to sugar intake based on social cognitive theory, perceptions of sugar intake, and health-related factors was conducted in October 2019 with 1,022 adults (502 men and 520 women) aged 19-49 years. The intake frequency of sugar-source food was divided into tertiles using percentiles based on the daily frequency. Results: The daily intake frequency of sugar-source foods was 4 times, with beverages (1.87 times/day) and sweetened coffee (0.81 times/day) being the highest among the food groups and types, respectively. The group with a high intake frequency of sugar-source food had a high negative outcome expectation for reducing sugar intake, and was in a home and social environment with easy access to sweet food. Women in this group showed low self-efficacy and poor behavioral capability in reducing sugar intake. Self-control had the lowest average score among the factors of social cognitive theory (2.56/5 points), followed by nutrition knowledge related to sugar (5.42/10 points). As a result of regression analysis, the social cognitive factor affecting the intake frequency of sugar-sourced foods was found to be home environment for both men and women. On the other hand, factors contributing to reducing sugar intake were positive outcome expectations for men and behavioral skills for women. Conclusion: Dietary education and nutritional interventions for adults, including changes in the home environment with easy access to sweet foods, can reduce sugar intake and raise positive expectations for reduced sugar intake.

This study attempted to explore the impact of sense of humor and stress coping styles among nursing students on adaptation to clinical practice. The study included 180 nursing students as participants, and data collection was conducted using self-administered questionnaires from April 15 to 26, 2024. The collected data underwent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. The research findings revealed that the sense of humor scored 3.52, stress coping styles scored 3.40, and adaptation to clinical practice scored 3.46. Adaptation to clinical practice according to general characteristics showed statistically significant differences based on major satisfaction (F=29.80, p<.001), clinical practice satisfaction (F=40.46, p<.001), relationships with peers in clinical practice (F=5.05, p<.001), and personality (t=-3.41, p<.05). Adaptation to clinical practice showed statistically significant positive correlations with sense of humor (r=.31, p<.001) and stress coping styles (r=.43, p<.001). The factors influencing adaptation to clinical practice were clinical practice satisfaction(β=.34, p<.001), stress coping styles (β=.29, p<.001), and major satisfaction (β=.23, p<.05), explaining 42% of the total variance.

This study estimates connectedness index among the US, China, Europe, Japan, and South Korea using monthly economic policy uncertainty (EPU) data from January 2000 to December 2023. The connectedness index allows us to analyze the effect of global economic uncertainty on domestic economic uncertainty. The EPU is used as a proxy for economic uncertainty. Inter-country connectedness index is computed from variance decomposition. The findings from forecast error variance decomposition show that three-fourths of total uncertainty comes from economic uncertainty in the own country and one-fourth of total uncertainty comes from economic uncertainty in the others. The analysis on net pairwise connectedness reveals that, even though the extent of the effect of economic uncertainty in one country from economic uncertainty in another country varies over time, economic uncertainty in South Korea, a small-open economy, is mainly affected by economic uncertainty in the others. The reverse situation rarely happens except in the specific occurrence such as the collapse of the credit bubble in 2003 and the subsequent years, the inter-Korean summit and North Korea-the US summit in 2018, and the period from the first outbreak of COVID-19 on the implementation of the government's severe regulation against COVID-19.

Objectives: Shift work is a stressful situation. It is important to know the factors associated with the ability to adapt to a shift work schedule. The aim of the present study was to investigate the association between sleep, as well as personality variables, and the resilience of shift work nurses. Method: Self-report questionnaires were administered to 95 nurses who worked in one national university hospital. Connor-Davidson resilience scale, hospital anxiety and depression scale, morningness-eveningness scale, Pittsburgh sleep quality index, other sleep-related questionnaires, and Korean defense style questionnaires were used. Results: Age, shift work duration, off-day oversleep, depression, anxiety, adaptive defense style, and self-suppressive defense style were significantly associated with resilience (p < 0.05). Multiple regression analysis showed that age (${\beta}=0.34$, p < 0.05), depression (${\beta}=-0.25$, p < 0.05), adaptive defense style (${\beta}=0.45$, p < 0.001), and self-suppressive defense style (${\beta}=-0.19$, p < 0.05) significantly predicted the resilience of shift work nurses. Concerning individual defense mechanisms, resignation (${\beta}=-0.20$, p < 0.05), sublimation (${\beta}=0.19$, p < 0.05), omnipotence (${\beta}=0.19$, p < 0.05), and humor (${\beta}=0.20$, p < 0.05) significantly predicted the resiliency. Conclusion: The findings indicate that a specific defense style and other mechanisms were associated with the resilience of shift work nurses. A future prospective study with more participants could further clarify the relationship between sleep-related variables, as well as personality factors, and resilience of shift work nurses.
