Aims: To examine the moderating effects of individual, family, and social factors on the relationship between adolescent exposure to media violence and attitudes towards school bullying. Design: A cross-sectional study. Methods: A total of 473 middle and high school students participated in a self-reported survey between August and October 2016. Self-reported questionnaires were used to measure perceived aggression, resilience, parental violence experience, parenting styles, satisfaction with school life, teacher attitudes towards school bullying, media violence exposure, and adolescent attitudes towards school bullying. The data were analyzed using descriptive statistics and hierarchical multiple regression. Results: Resilience (an individual factor; β = −0.48, p = .049) and parenting styles (a family factor; β = −0.77, p = .045) moderated the negative influence of media violence exposure on adolescent attitudes towards school bullying. The findings indicated that higher individual resilience and parents with more positive parenting styles could reduce the harmful effects of media violence exposure on adolescent attitudes towards school bullying. The teachers' attitudes towards school bullying (a school factor) contributed to predicting the adolescents' attitudes towards school bullying. However, no moderating effect of school factors was found. Conclusion: Resilience and parenting styles are important socio-ecological factors influencing the relationship between adolescent exposure to media violence and attitudes towards school bullying. Impact: Three types of intervention programmes can be suggested based on the results of this study. Reinforcing individual resilience and positive parenting styles should be considered important in developing intervention programmes targeted at eliminating the adverse effects of media violence exposure. Intervention programmes to develop parenting styles to increase the resilience of adolescents can also be considered. Lastly, programmes to screen for adverse outcomes of media violence exposure, low resilience, and poor parenting styles need to be developed.

Purpose: Rectal prolapse is still a relatively understudied medical condition, especially in women, whereas physical symptoms, depressive symptoms, and quality of life (QOL) in women with pelvic organ prolapse have been steadily studied. This study aimed to examine the interaction and main effects of physical and depressive symptoms on physical and mental QOL of women seeking care for rectal prolapse in Korea. Methods: Ninety-two women with rectal prolapse were recruited from a colorectal surgery clinic of a tertiary teaching hospital in Gwangju, Korea. Physical symptoms related to rectal prolapse (pelvic organ prolapse distress, POPD; colorectal-anal distress, CRAD; and urinary distress, UD), depression, and QOL were measured. The data were analyzed using descriptive statistics, Pearson correlation coefficient, and two-way analysis of variance. Results: The interaction between POPD symptoms and depressive symptoms (F=4.51, p=.037) affected physical QOL. The interaction between POPD (F=9.66, p=0.003) and CRAD symptoms (F=7.48, p=.008), respectively, and depressive symptoms affected mental QOL. Depressive symptoms had a significant main effect on the physical QOL in the CRAD (F=6.22, p=.014) and UD (F=6.01, p=.016) groups and on mental QOL in the UD group (F=24.54, p<.000).Conclusion: Physical and depressive symptoms should be considered together to improve the QOL in women with rectal prolapse. Nursing interventions to decrease rectal prolapse-related physical and depressive symptoms are required to improve QOL in women with symptomatic rectal prolapse.

This study aimed to identify the knowledge structures of Korean and international nursing studies on premature infants using text network analysis, which represents a text as a network graph that describes how keywords are linked. This network graph refers to a knowledge structure. International and Korean journal databases were searched to extract nursing studies regarding premature infants published in academic journals from 1998 to 2020. Abstracts from the selected studies were analyzed using the following four steps: word extraction and refinement, keyword extraction, co-occurrence matrix generation, and text network visualization. The results demonstrated that 182 Korean and 2502 international studies were published. The common keywords of Korean and international studies were "kangaroo mother care," "stress," and "child." The keywords of the international studies had more branches linking to other keywords than those of the Korean studies. Thus, the knowledge structure of international studies included diverse concepts. These findings will serve as important guidance for future research worldwide. Furthermore, studies to develop a more comprehensive knowledge structure of international research on premature infants are needed. The knowledge structure of Korean studies mainly included concepts related to mothers. Korean studies regarding hospitalized premature infants and communication with parents need to be conducted.

This study aimed to investigate the public’s experience of online reservation of residual COVID-19 vaccines in an additional vaccination program. Online reservation was used to predict the vaccination rate. A sample of 620 participants completed the online survey between July and August 2021. About 38% of the participants made the online reservation. About 91% had a vaccination intention. Online reservations showed significant differences in their distribution according to age group, educational level, past flu shot experience, and COVID-19 vaccination intention. A negative experience was the most common response, which was mostly attributed to the difficulty in making an online reservation due to reservations being full. Positive experiences included updated information and notifications on the residual vaccines available, being able to choose a vaccination clinic, and the ease of making, changing, and canceling a reservation. About 72% reported the positive effect of residual vaccine usage on herd immunity. The results of this study suggest that when developing another online reservation program for vaccination, it is necessary to consider and address the negative experiences of the public with online reservations. The additional vaccinations may have resulted in an increased vaccination rate. Vaccination reservations can be used as an indicator to predict the actual vaccination rate and as a measure of a positive attitude toward COVID-19 vaccination.
