This paper reviews the global effect of the coronavirus disease 2019 (COVID-19) pandemic on the mental health of children and adolescents in South Korea, the U.S., Japan, and China. We reviewed research on deteriorated mental health, including increased suicide, suicidal thoughts, and self-harm. Various studies have shown that students' mental health issues, such as depression and anxiety, have worsened during the COVID-19 pandemic. Furthermore, the number of students who committed suicide has significantly increased in the U.S. and Japan. Factors such as prior mental health status, change in daily routine, reduced physical activity, excessive screen time, overuse of electronic devices, and reduced social support have been reported to have a significant effect. The chain of deteriorating mental health among the youth began at the onset of COVID-19, social distancing, and school closure. As youths began to stay at home instead of going to school, they lost opportunities to connect with their friends or teachers, who could provide support outside of their homes. Young people spent less time on physical activity and more time online, which damaged their sleeping schedule and daily routine. In preparing for the post-pandemic phase, we should thoroughly analyze the long-term effects of the pandemic on youth mental health, while simultaneously tackling current imminent issues.

Purpose: This study examines the role of leaders of sport organizations from the perspectives of rank-and-file volunteers. Specifically, the study explores which factors are important in leading volunteers and how rank-and-filers interact with their leaders. Research design, data, and methodology: This study reviews a comprehensive literature on volunteer and leadership theories which are trait theory, behavior theory, and contingency theory. Given the comprehension of prior structure of knowledge on leadership, the study provides a structure of knowledge on volunteer and leadership in sport context and discusses managerial implications for leaders in sport organization. Results: With an exploration of sport leadership, this study proposes a volunteer classification model which presents four-volunteer types: professional volunteer, company volunteer, general volunteer, and school volunteer. Furthermore, this study discussed managerial implications for sport organization leaders. Conclusions: Paid employees may be prepared to accept a job and its requirements mainly due to economic benefits. Volunteers, however, do not pursue economic benefits through their activity. Different types of motivation between paid employees and volunteers bring to surface how a leader influences volunteer effectively. A conceptual volunteer clarification model could be examined in real world situations. Insights for future studies were discussed.

본 연구는 글로벌 기업의 집단형 문화와 합리형 문화 간의 관계에서 여성리더 특성의 매개효과를 검증하고자 하는 것이 연구목적이다. 본 연구를 통하여 촉진자, 선도자, 생산자, 지시자 리더십 간의 관계에서 여성리더의 직위와 경력이 매개효과로 미치는 영향을 분석하고자 하였다. 개념적 연구모형은 집단형 문화, 여성리더 특성, 합리형 문화의 3개 요인으로 설계되었다. 글로벌기업을 대상으로 리더십 유형과 조직문화와 관련된 500개의 조사대상표본에 기초해서 구조방정식모형을 사용하여 집단형 문화와 합리형 문화 간의 관계에서 여성리더 특성의 매개효과를 분석한 결과 다음과 같은 연구결과를 얻었다. 첫째, 촉진자 리더십은 여성리더의 직위와 경력에 긍정적인 영향을 미쳤다. 둘째, 선도자 리더십은 여성리더의 경력에 긍정적인 영향을 미친 반면에, 여성리더의 직위에 직접적인 영향을 미치지 않았다. 셋째, 여성 리더의 직위와 경력은 생산자 리더십에 직접적인 영향을 미치지 않았다. 넷째, 여성 리더의 직위와 경력은 지시자 리더십에 긍정적인 영향을 미쳤다. 다섯째, 촉진자 리더십은 생산자 리더십에 긍정적인 영향을 미쳤고, 선도자 리더십은 지시자 리더십에 긍정적인 영향을 미쳤다. 여성리더 특성의 매개효과를 통제한 상태에서 본 연구의 결과는 집단형 문화가 합리형 문화에 미치는 영향을 실증연구를 통해서 검증함으로서 학술적 기여도를 높였으며, 또한 정책적, 혹은 실무적 시사점을 제시한 연구이다. 본 연구는 리더십 유형과 조직문화 연구 분야에서 여성리더의 직위와 경력 변수를 사용하여 매개효과를 검증하였다는 점에서 의미 있는 연구이다.

The purpose of this study was is to investigate the relationship between transformational leadership in families and psychological well-being and career decision-making self-efficacy. The samples were randomly selected from high school students studying liberal arts in Seoul. 400 survey questionnaires were distributed March 11 through 18, 2010. Among them, 386 completed surveys were utilized as the data for the statistic analyses. SPSS were applied. The main results of the study are as follows. First, adolescent children of mothers with leadership have higher psychological well-being than those from families of mothers without leadership. This has been determined as a result of reviewing the psychological well-being of adolescent children according to their mothers' transformational leadership in the family. Second, the adolescent group with mothers who show transformational leadership in managing the home have higher career decision-making self-efficacy than the group without such mothers. This was determined as a result of reviewing adolescent children's career decision-making self-efficacy according to mother's transformational leadership level in the family. Third, career decision-making self-efficacy according to adolescents' psychological well-being show positive relations by group. That is, adolescents living table lives are more positive about their future. Lastly, when comparing the relative contribution of the mother's transformational leadership in the family and psychological well-being on career decision-making self-efficacy, it has gained more credibility as stage ads. Based on the results, when mothers nurture children with a affection-based autonomy, children gain higher psychological well-being, which leads to firm beliefs about constructive futures. Therefore, for successful and systematic career development, CEO mothers' transformational leadership should serve as its foundation.

본 연구는 해외 글로벌 강소기업들의 핵심성공요인, 즉 히든챔피언의 원리를 바탕으로 국내 글로벌 강소기업들의 특성을 탐색하고자 하였다. 이를 위해 국내 11개 글로벌 강소기업들을 대상으로 사례 연구를 수행하여 해외 히든 챔피언들의 성공요인이 어떻게 적용되고 있는지 살펴보고, 이를 바탕으로 국내 글로벌 강소기업들의 특성을 분석하였다. 해외의 히든챔피언들이 보유하고 있는 성공원리인 시장을 지배하는 목표와 자체생산 능력, 고성과를 내는 직원들, 핵심 사업에의 집중과 지속적 혁신, 고객 친밀성과 세계시장 지향 등의 원칙들은 국내 글로벌 강소기업들의 특성에 대부분 적용되고 있었으나, 구체적으로 적용되는 과정에서는 보다 세분화된 형태로 다르게 나타나고 있었다. 국내 중소기업들이 글로벌 강소기업으로 성장하기 위해서는, 국내 글로벌 강소기업들도 공통된 성공요인으로 보유하고 있는 해외 히든 챔피언들의 성공원리와 이것이 국내 글로벌 강소기업들에 적용되는 과정을 자세히 살펴봄으로써, 자사의 특성에 맞는 활용 방안을 모색해야 할 것이다.

In the last decade, the effect of digitalization was the most cited issue in economic discourse, especially since technological advances, automation, and artificial intelligence are the key to the future discussions. Unemployment is one of the most important and continuous debates, especially in times of crisis due to the COVID-19 pandemic. Therefore, this study aims to analyze the influence of leadership style in innovation organizations to deal with the crisis. In this study, a non-probability purposive sampling method was used. A total of 377 respondents were from LinkedIn social media in Indonesia, with the criteria of employees who have worked for at least 6 years. The structural equation model was analyzed with Amos 25.0. The results show that virtual, servant, and transformational leadership influence employee creativity. Moreover, employee creativity strongly influences organizational innovation; therefore, a new model was found to meet the challenges during the COVID-19 pandemic crisis, which is leadership. Therefore, these results are useful for managers to overcome challenges during the COVID-19 pandemic crisis to manage employee creativity for a better innovative organization and make science a reference for finding solutions to the global wave of unemployment in the revolution 5.0 era.

This study aims to identify the influence of paradoxical leadership on proactive work behavior mediated through psychological safety in the hotel industry. This study employs survey data of five-star deluxe hotels in South Korea using convenience sampling. The number of 270 cases was used for analysis and the hypotheses were analyzed with structural equation modeling and AMOS 20. Paradoxical leadership includes five sub-variables of self-centeredness with other-centeredness (SO) distance and closeness (DC), uniformly and individualization (UI), work requirements and flexibility (RF), and decision control and autonomy (CA). The results indicate that DC, UI, and CA positively influence psychological safety. Further, RF and CA make a positive impact on proactive work. Psychological safety fully mediates the effect of DC and UI on proactive work behavior and partially mediates the effect of CA on it. The findings of this study suggest that the impact of paradoxical leadership on proactive work behavior can be strengthened when this relationship is accompanied with psychological safety and other mediation variables for the relationship need to be further investigated. This study suggests how hotel managers enhance the level of proactive work behavior by training themselves to be paradoxical leaders and making psychologically safe environment.
