Abstract Background The debriefing process after health care simulations should provide a psychologically safe learning environment for nursing students. Case video-based debriefing on a simulation of high-risk neonatal care can help nursing students feel psychologically safe and make learning more effective. In this study, we developed case video-based debriefing materials for a simulation of high-risk neonatal care for nursing students in South Korea and evaluated their effects. Methods This mixed-methods study, consisting of a survey and an in-depth interview, was conducted between August and December 2022. The participants were 27 nursing students for the development of the case video-based debriefing and 51 nursing students for the evaluation of its effects (25 in the experimental group and 26 in the control group) at a university in South Korea. A case video-based debriefing on a simulation of high-risk neonatal care was developed, and the experimental group took part in case video-based debriefing. The participants’ self-efficacy, critical thinking, state anxiety, and satisfaction with practice were examined. The experimental group’s learning experiences were explored. Quantitative data were analyzed using the chi-square test, the unpaired t-test, and repeated-measures analysis of variance. Qualitative content analysis was conducted. Results In the experimental group, critical thinking and satisfaction with practice increased to a greater extent than in the control group. However, the changes in self-efficacy and state anxiety were not significantly different between the experimental and control groups. Four categories were extracted from nursing students who participated in the case video-based debriefing: “learning facilitated by the simulation,” “expanded learning,” “safe learning environment,” and “efficient utilization of case videos.” Conclusions Case video-based debriefing on a simulation of high-risk neonatal care effectively enhanced nursing students’ critical thinking and satisfaction with practice, and it will be utilized to improve nursing students’ competency in high-risk neonatal care.

Purpose: We developed a virtual reality (VR) program for use in pediatric nursing practicums to help nursing students learn to measure vital signs in children.Methods: The analysis, design, development, implementation, and evaluation model was employed between July 2021 and December 2021 at a university in South Korea. In the analysis phase, in-depth interviews were conducted with four nursing students, two nursing school graduates, and four experts. The topic and contents of the VR program were settled in the design phase. The VR program was developed and subsequently used and evaluated by 20 nursing students and four experts.Results: The contents of the VR program for pediatric nursing practicums included the measurement of vital signs in a newborn baby and a young child, as well as an evaluation system. The mean score for the nursing students' satisfaction with practice was 4.02 out of 5 points. The mean scores for overall satisfaction with the VR program were 4.15 and 4.79 out of 5 points for nursing students and experts, respectively.Conclusion: The VR program developed in this study allows nursing students to practice measuring vital signs in children, thus improving the students' clinical performance in pediatric nursing.

Purpose: This study aimed to explore nursing students' experiences of neonatal nursing simulations using peer tutoring. Methods: In this qualitative content analysis study, data were collected using a narrative survey and focus group interviews with 27 third-year nursing students and six fourth-year nursing students from April to May 2022. Content analysis of the collected data was conducted. Results: Four categories—"stabilizing emotionally through each other", "advancing together", "difficulties in relationships", and "hoping to continue"—and nine sub-categories were extracted. The sub-categories "reduced burden" and "gaining confidence" were grouped into the first category, "stabilizing emotionally through each other". The sub-categories "being motivated to learn," "increased learning ability", and "preparation as a process" were grouped under "advancing together", and "attitudes affecting study environment" and "depending on help" were grouped into the third category of "difficulties in relationships". The fourth category of "hoping to continue" had "wanting to supplement for development" and "wanting to participate in different roles" as sub-categories. Conclusion: Based on the results of this study, we expect pediatric nursing practicum education to improve through the active use of neonatal nursing simulation education incorporating peer tutoring.

Project-based learning (PjBL) allows nursing students to participate in real problem-solving, construct knowledge, and improve their nursing skills in the process of accomplishing meaningful projects. This study was conducted to develop a PjBL program on high-risk newborn care for nursing students and evaluate its effects. A quasi-experimental study using a nonequivalent control group pretest–posttest design was employed between June and December 2021. The participants were 45 nursing students (24 in the experimental group and 21 in the control group). A PjBL program involving the creation of an educational video clip about high-risk newborn care for nursing students was developed, and the experimental group took part in PjBL. The participants’ nursing competency for high-risk newborns, self-leadership, and practicum-related stress were assessed. In the experimental group, nursing competency for high-risk newborns increased and practicum-related stress decreased to a greater extent than in the control group. However, the change in self-leadership was not significantly different between the experimental and control groups. PjBL effectively improved students’ nursing competency for high-risk newborns and decreased their practicum-related stress. PjBL will be utilized to enhance nursing students’ expertise in high-risk newborn care.

Purpose: This study was conducted to investigate the educational needs of parents of infants and toddlers with congenital heart disease (CHD) after hospital discharge.Methods: Qualitative content analysis was conducted of in-depth interviews of eight parents, and the results of an online survey of 171 parents were analyzed quantitatively.Results: Only 16.4% of parents reported that they had received education after hospital discharge on how to provide care for a child with CHD at home. The main reason why parents did not receive education on this topic was that they did not have sufficient opportunities or information (75.5%). In addition, 97.1% of parents stated that they needed educational programs that would be available at home after discharge. In terms of specific educational content, parents expressed the highest needs for education on the symptoms of CHD and ways to cope with them, the prognosis of CHD, and the growth and development of infants and toddlers with CHD.Conclusion: The study showed that parents’ educational needs were high in many ways. However, the information and educational opportunities offered after discharge were insufficient compared to those needs. Further research is needed to develop post-hospital educational programs that meet their needs.

Purpose: This study was conducted to identify correlations between how much fever management information mothers obtained from the internet and their actual knowledge and practices of fever management. Methods: This was a descriptive survey of 172 mothers with children aged between 0 and 3 attending five daycare centers located in the city of Daegu. Descriptive statistics, the independent t-test or one-way analysis of variance, and Pearson correlation coefficients were used for data analysis.Results: In total, 75% of the mothers had searched the internet for information on fever management. The overwhelming majority (92.2%) used information from the internet to help manage fever in their children. Positive correlations were found between acquiring fever management information from the internet and fever management practices (r=.18, <i>p</i>=.038), and between mother’s knowledge and practices of fever management (r=.27, <i>p</i><.001). Conclusion: Based on the results of this study, to improve fever management practices, it is necessary to increase mothers’ knowledge. Therefore, resources should be developed to augment mothers’ knowledge of fever management through the internet.

Purpose: This study was conducted to examine factors associated with obesity among Korean adolescents. Methods: The participants were 436 Korean adolescents aged 12~18 years who took part in the seventh Korea National Health and Nutrition Examination Survey (2016). The data were analyzed by descriptive statistics, the x test, one-way analysis of variance, and multinomial logistic regression using complex sample analysis. Results: Among the participants, 9.7% were classified as being obese, and 11.9% as being overweight. Several health parameters, including systolic blood pressure, diastolic blood pressure, waist circumference, and triglyceride, fasting blood sugar, and alanine aminotransferase levels, varied according to obesity. Distorted perceptions of body shape showed a significant negative association with overweight, and carbohydrate intake was negatively associated with obesity. Conclusion: These findings indicate that obesity in Korean adolescents was associated with lifestyle and health parameters. Therefore, intervention programs for obese or overweight adolescents should focus on preventing them from developing health problems.

Purpose: This study was conducted to characterize the influence of achievement motivation and the parent-child relationship on ego identity in Korean nursing students. Methods: The participants were 217 Korean nursing students in the first and fourth year of university. Data were collected through self-report questionnaires composed of items assessing ego identity, achievement motivation, the parent-child relationship, and demographic characteristics. The data were analyzed using descriptive statistics, one-way analysis of variance, the x 2 test, and multinomial logistic regression analysis. Results: Ego identity was related to achievement motivation; moreover, the achievement motivation of students with moratorium and achieved identity status was significantly higher than that of students with low-profile moratorium and diffused identity statuses. Ego identity was not related to the mother-child relationship, but the father-child relationship of students in foreclosure was significantly higher than that of students with diffused identity status. The factors influencing achieved identity compared to diffused identity were achievement motivation, year in school, satisfaction with school, and having religious beliefs. Conclusion: These findings indicate that nursing students ’ ego identity attainment was more influenced by achievement motivation than by the parent-child relationship. It emphasizes that highly motivated students can develop their own identities regardless of the parent-child relationship.

PURPOSE
This study was done to develop a cell phone addiction scale for Korean adolescents.
METHODS
The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 577 adolescents in two middle schools and three high schools. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data.
RESULTS
Twenty items were selected for the final scale, and categorized into 3 factors explaining 55.45% of total variance. The factors were labeled as withdrawal/tolerance (7 items), life dysfunction (6 items), and compulsion/persistence (7 items). The scores for the scale were significantly correlated with self-control, impulsiveness, and cell phone use. Cronbach's alpha coefficient for the 20 items was .92. Scale scores identified students as cell phone addicted, heavy users, or average users.
CONCLUSION
The above findings indicate that the cell phone addiction scale has good validity and reliability when used with Korean adolescents.

PURPOSE
This study was done to investigate cybersex addiction, gender egalitarianism, sexual attitude and the allowance of sexual violence in adolescents, and to identify the relationships among these variables.
METHOD
The participants were 690 students from two middle schools and three high schools in Seoul. Data was collected through self-report questionnaires which included a cybersex addiction index, a Korean gender egalitarianism scale for adolescents, a sexual attitude scale and a scale for the allowance of sexual violence. The data was analyzed using the SPSS program.
RESULTS
Of the adolescents, 93.3% reported not being addicted to cybersex, 5.7% reported being mildly addicted, 0.4% moderately addicted, and 0.6% severely addicted. Cybersex addiction, gender egalitarianism, sexual attitude and the allowance of sexual violence in adolescents were different according to general characteristics. Cybersex addiction of adolescents correlated with gender egalitarianism, sexual attitude and the allowance of sexual violence.
CONCLUSION
Gender egalitarianism, sexual attitude and the allowance of sexual violence in adolescents were influenced by cybersex addiction. Therefore, nursing interventions for prevention and management of cybersex addiction need to be developed and provided to adolescents. In addition, varied programs for teaching sexuality to adolescents should be developed and provided.

PURPOSE
The purposes of this study were 1) to compare the contribution of demographic-behavioral variables and psychological variables in explaining the variance of depression, 2) identify the most important predictors of depression for Korean female adolescents.
METHOD
The participants were 840 female adolescents. Data was collected through self-report questionnaires, which were constructed to include demographicbehavioral factors, self-esteem, hostility, hopelessness, and depression. Data was analyzed using the SPSS program.
RESULT
Female adolescents' demographicbehavioral variables explained 17% of the variance in depression, and perceived physical health status, history of physical abuse, smoking, satisfaction of body weight, parental alcohol abuse, parental divorce, and history of suicidal attempt were the significant predictors of depression for female adolescents. Psychological variables explained 50% of the variance in depression, and self-esteem, hostility, and hopelessness were the significant predictors of depression for female adolescents. The significant predictors of depression among female adolescents' demographicbehavioral variables and psychological variables were self-esteem, hostility, hopelessness, perceived physical health status, parental alcohol problem, and history of physical abuse, explaining 52% of the variance in depression.
CONCLUSION
In order to reduce depression in female adolescents, it is necessary to design an intervention program that emphasizes improving self-esteem while reducing hostility and hopelessness.

The purpose of this study was to examine the evidence to determine if there are gender differences in suicidal ideation of adolescents. This study examined the main effect of risk factors from 5 domains and protective factors from 1 domain in relation to suicidal ideation by gender and identified the most important predictors of suicidal ideation for males (N = 654) and females (N = 658). This study was a cross-sectional survey, and data were collected through self-report questionnaires. In the univariate analysis, especially, risk factors from behavioral variables and psychosocial-environmental variables appeared to be gender skewed. For males, all behavioral variables were predictive of suicidal ideation. For the females, unlike the males, Wang-tta or victim of bullying behavior and sexual orientation as behavioral variables were predictive of suicidal ideation. For males, parental divorce and parental alcohol abuse as psychosocial-environmental variables were predictive of suicidal ideation. For the females, again unlike for the males, all the psychosocial-environmental variables were not predictive of suicidal ideation. The most important predictors of suicidal ideation for males as a result of the multivariate analysis were history of suicidal attempt, depression, hostility, smoking, parental alcohol abuse, communication with friends, and self-esteem. The most important predictors of suicidal ideation for females as a result of the multivariate analysis were depression, hostility, sexual orientation, and self-esteem. These results would indicate that an effective suicide screening and prevention program for adolescents should consider gender differences.

PURPOSE
This study was done to investigate the satisfaction with life in adolescents, and to identify factors affecting satisfaction with life for them.
METHOD
The participants were 1,057 adolescents. Data was collected through self-report questionnaires which were constructed to include satisfaction with life, self-esteem, hostility and hopelessness. The data was analyzed using the SPSS program.
RESULT
Satisfaction with life for adolescents was significantly different according to school type, grade, scholastic achievement, religion, monthly income of family, conversation with parents and conversation with friends. Satisfaction with life in adolescents correlated with self-esteem, hostility and hopelessness. Significant predictors influencing satisfaction with life in adolescents were self-esteem, hopelessness, school type, conversation with parents, monthly income of family and religion, and these predictors accounted for 37.8% of the variance in satisfaction with life.
CONCLUSION
The above findings indicate that satisfaction with life in adolescents is influenced by self-esteem, hostility and hopelessness. Therefore when nursing interventions are developed to improve satisfaction with life in adolescents, these factors need to be considered.
