Purpose: This study aimed to improve nursing practice efficiency by analyzing and comparing the emotional labor, job stress, and performance of nurses in comprehensive nursing care wards and in general wards. Methods: The study surveyed 151 nurses in comprehensive nursing care and general wards. The results were analyzed by ${\chi}$ 2test, ANOVA, and Pearson's correlation coefficient. Results: There were no statistically significant differences in terms of emotional labor, job stress, and performance for the two different types of nurses. Statistically significant positive correlations were noted between job stress and emotional labor, nursing performance, emotional labor, and job stress in the comprehensive nursing care wards, and between job stress and emotional labor, and nursing performance in the general wards. Conclusion: A longer duration of direct nursing in comprehensive nursing care wards tended to increase, emotional labor and job stress. However, the quality of nursing provided to patients tended to improve. Therefore, it is necessary to establish an institutional plan for carrying out efficient nursing while reducing emotional labor and job stress among nurses in comprehensive nursing care wards.

본 연구는 보육교사가 인식한 원장의 진성리더십과 조직공정성, 직무만족도의 상관관계를 알아보고, 보육교사가 인식한 원장의 진성리더십과 조직공정성이 직무만족도 미치는 영향이 무엇인지 알아보는데 목적이 있다. 이를 위해 서울과 경기도에 소재한 어린이집에서 재직 중인 보육교사 288명을 대상으로 설문조사를 하였으며, 분석 방법으로는 빈도분석과 백분율분석, 내적 신뢰도 분석 및 상관분석, 그리고 다중회귀분석을 실시하였다. 연구결과 첫째, 보육교사가 인식한 원장의 진성리더십과 조직공정성, 직무만족도 간에는 모두 유의미한 정적 상관이 있는 것으로 나타났다. 둘째, 보육교사가 인식한 원장의 진성리더십과 조직공정성, 직무만족도에 미치는 영향을 살펴본 결과, 직무만족도에 영향을 미치는 요인들의 상대적 영향력은 조직공정성이 보육교사가 인식한 원장의 진성리더십에 비해 큰 것으로 나타났으며 이와 같은 결과는 보육교사가 인식한 원장의 진성리더십과 조직공정성 모두 보육교사의 전문성 신장에 대한 만족도에 긍정적인 영향을 미치는 것을 의미한다. 본 연구결과를 통해 보육교사가 인식한 원장의 진성리더십과 조직공정성이 보육현장에서 매우 중요하며, 이를 바탕으로 보육교사가 직무에 만족하고 몰입하여 보육의 질 향상을 도모하고, 그에 따른 보육 정책 마련에 유용한 정보를 제공하는데 의의가 있다. The purpose of this study was to explore the effects of child-care center directors’ authentic leadership and organizational justice perceived by teachers on their job satisfaction. The participants of this study were three hundred thirty child-care teachers in Seoul and Gyeonggi Province, with conducting survey questionnaires. The methodology included frequency and percentage analyses, internal reliability assessment, correlation studies, and multiple regression analyses. As a result of the research, first, a significant positive correlation was found between child-care teachers' perceptions of their directors' authentic leadership, organizational justice, and their job satisfaction. Second, regarding the impact on job satisfaction, the organizational justice had a greater effect than the perceived authentic leadership of directors. These findings emphasize that both authentic leadership and organizational justice, as recognized by child-care teachers, are essential for heightening their satisfaction with opportunities for professional development. It is anticipated that acknowledging the significant role of director’s authentic leadership and organizational justice can not only enhance job satisfaction and commitment among child-care teachers but also provide useful information for the development in effective child-care policies.
