  • The purpose of this study is to investigate influencing factors of nursing students' academic stress focusing on dimensions of empathy, ego-resilience, and stress coping strategies. Academic stress, dimensions of empathy, ego-resilience, and stress coping strategies among subjects were collected using structured questionnaires from 305 nursing students between November 1, 2015 and November 30, 2015. The results of this study showed that the factors affecting nursing students' academic stress were grade, personality orientation, major satisfaction, ego-resilience and emotion focused coping style, and the total explanatory power was 54.1%. To improve nursing students' academic stress, it is necessary to pay attention to the nursing students who are in their upper grades, extroverted, and with low major satisfaction. In developing a program to reduce academic stress, it is thought that it is necessary to include measures to raise the level of ego-resilience and to improve the level of emotion focused coping style among stress-coping strategies, and to conduct subsequent research to identify pathways in which the dimensions of empathy, ego-resilience and stress-coping strategies affect academic stress.

  • Surgical process of oral and maxillofacial area as well as dental treatment are stressful situations to the patients. It is well known that serum level of stress hormones including adrenocorticotropic hormone(ACTH) and cortisol increase when the body is exposed to stress. However, there have been few studies on demographic and clinical factors related with stress. Therefore, the purpose of this study was to supply data to cope with stress more comprehensively and efficiently by analyzing the effect of factors related with stress in addition to surgical procedure. Prospective cohort study method was selected. Serum levels of ACTH and cortisol were measured by sampling bloods pre-operatively and post-operatively from 45 patients who had been operated at the Bundang Jesaeng Hospital department of oral and maxillofacial surgery. To evaluate factors associated with stress, patients were classified according to gender, age, method of payment(insurance or self), experiences of operation, kind of operations(expected operations or unexpected operations). Relative risk was calculated to assess relationships between changes of serum level of ACTH and cortisol and factors related with stress, whereas Chi-square analysis was executed to evaluate statistical significance. With regard to serum level of ACTH, relative risk was 1.3 in the group of the patients who were less than 40 years old. With regard to serum level of cortisol, relative risk was 1.8 for women compared with men, 1.4 in the group of the patients who were less than 40 years old and 1.6 in the group of the patients who had not experienced any other operations. In addition to surgical procedure, factors related with stress included gender, age, method of payments, experiences of operation and kind of operations. Therefore, we should provide comprehensive schemes to reduce stress of the patients going through oral and maxillofacial surgery.

  • Purpose: Coronavirus disease 2019 (COVID-19) has spread widely throughout the world, causing psychological problems such as fear, anxiety, and stress. During the COVID-19 pandemic, pregnant women have been concerned about both their own health and the health of their fetuses, and these concerns could negatively affect maternal-fetal attachment. Thus, this study aimed to explore the level of COVID-19 stress, resilience, and maternal-fetal attachment among pregnant women during the COVID-19 pandemic, and to identify factors influencing maternal-fetal attachment. Methods: In total, 118 pregnant women past 20 weeks gestation were recruited from two maternity clinics in Daegu, Korea, to participate in this descriptive correlational study during COVID-19. The factors influencing maternal-fetal attachment were analyzed using hierarchical multiple regression analysis. Results: The mean scores for COVID-19 stress, resilience, and maternal-fetal attachment were 57.18±10.32 out of 84, 67.32±15.09 out of 100, and 77.23±9.00 out of 96, respectively. Nulliparous pregnant women reported greater maternal-fetal attachment than multiparous pregnant women (p=.003). Religious pregnant women also reported greater maternal-fetal attachment than non-religious pregnant women (p=.039). Resilience (β=.29, p=.002), COVID-19 stress (β=.20, p=.030) and parity (β=-.17, p=.047) were factors influencing maternal-fetal attachment, and these factors explained 26.4% of the variance in maternal-fetal attachment (F=10.12, p<.001). Conclusion: Converse to common sense, COVID-19 stress exerted a positive influence on maternal-fetal attachment in pregnant women during the COVID-19 pandemic. Healthcare providers need to recognize the positive influence of COVID-19 stress and implement intervention strategies to strengthen resilience in pregnant women to improve maternal-fetal attachment.

  • The study examines the effects of local environmental factors on stress among young and senior single-person households. We analyzed the '2019 Community Health Survey' by employing logistic regression analysis. The empirical results are as follows: First, there are greater differences in stress factors between young single-and multi-person households than senior single-and multi-person households; Second, stress among young single-person households was mainly influenced by physical environmental factors while stress among senior single-person households was influenced by both physical and social environmental factors. The results suggest that customized support at the local level is necessary in consideration of age-specific characteristics and stress vulnerabilities when promoting policies for the promotion of mental health among single-person households.
