Objective: The purpose of this study is to investigate the moderating role of Ego-Resilience between Peer Attachment and Mobile Phone Dependency in late adolescence. Methods: The participants were 2056 third year high school adolescents (1,041 boys and 1,015 girls) from the Korea Youth Panel Study (KYPS), a national representative of Korean Children and adolescence. Hierarchical Regression was used for data analysis. Results: First, the correlation between peer attachment, ego-resilience and mobile phone dependency were all significant. Second, ego-resilience takes the role of moderator for mobile phone dependency. In detail, ego-resilience relieves the mobile phone dependency caused by 'peer relationships' or 'conflict in peer relationships. Conclusion/Implications: Ego-resilience was found to control the relationship between peer attachment and mobile phone dependency. Therefore, in order to lower the dependence of mobile phones in adolescents with low peer attachment, a program that can enhance ego-resilience is needed.

Objectives: This study aimed to investigate the association between how often Korean adolescents watch Mukbang and Cookbang videos and their dietary habits. Methods: Data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 was analyzed for this study. The study included 51,850 middle and high school students and assessed various aspects, including demographics, frequency of watching Mukbang and Cookbang videos per week, dietary habits, health behaviors, and mental health factors. Results: Nearly a third (29.3%) of Korean adolescents watched Mukbang and Cookbang videos one to four times a week, while 13.5% watched them more than five times weekly. Females, those with lower academic achievement, and those from lower socioeconomic backgrounds were significantly more likely to be frequent viewers (P < 0.001). Increased viewing frequency was associated with poorer dietary habits. Adolescents who watched more frequently were less likely to eat breakfast and consume fruits and milk, while their consumption of fast food, high-caffeine drinks, sugary drinks, and late-night snacks increased (P < 0.001). Higher viewing frequency correlated with increased feelings of stress, depression, and loneliness (P < 0.001). Logistic regression analysis confirmed these associations. More frequent viewers were significantly less likely to eat breakfast (odds ratio (OR), 0.63; 95% confidence interval (CI), 0.58-0.68), and more likely to consume fast food (OR, 1.85; 95% CI, 1.69-2.02), high-caffeine drinks (OR, 1.43; 95% CI, 1.30-1.56), sugary drinks (OR, 1.54; 95% CI, 1.41-1.67), and late-night snacks (OR, 1.37; 95% CI, 1.25-1.51). Conclusions: Our findings suggest that frequent exposure to Mukbang and Cookbang content is linked to unhealthy dietary habits in adolescents. Educational programs may be necessary to mitigate the potential for these videos to negatively influence dietary choices.

Purpose: With the development of media, the ways adolescents can obtain information related to sexual health have diversified. Prior quantitative research on adolescents' sexual health information seeking behaviors (HISB) has limitations in grasping the details, and sexual issues of adolescents have tended to be underreported in quantitative studies. It is necessary to explore sexual HISB through an integrative review of qualitative research. The aim of the study was to analyze the literature on sexual HISB among adolescents, focusing on qualitative research. Methods: An integrative review was undertaken to explore the studies conducted between 2009 and 2018 that addressed sexual HISB such as source preferences, perceived trustworthiness, and tendency according to age and gender among adolescents. Results: Seven studies met the selection criteria and were analyzed according different sexual HISB. It was identified that adolescents preferred trustworthy sources and had a pattern of reviewing and comparing the content among diverse sources to confirm the quality of the information. Female adolescents valued privacy and confidentiality, while male adolescents would like to earn information along with their peers and perceived it as an opportunity to exchange their experiences and thoughts. Late adolescents preferred to seek sexual health information from peers and on the internet such as websites and social platforms compared to early adolescents. Conclusion: This study is significant in that it provides evidence that can be applied when developing programs for promoting sexual health in adolescents. It is suggested that programs should focus on building trustworthiness and consider differences in age and gender to improve the use of sexual health information among adolescents.

Purpose: The purpose of this study was to examine the effects of electroencephalogram (EEG) biofeedback training for emotion regulation and brain homeostasis on anxiety about COVID-19 infection, impulsivity, anger rumination, meta-mood, and self-regulation ability of late adolescents in the prolonged COVID-19 pandemic situation. Methods: A non-equivalent control group pretest-posttest design was used. The participants included 55 late adolescents in the experimental and control groups. The variables were evaluated using quantitative EEG at pre-post time points in the experimental group. The experimental groups received 10 sessions using the three-band protocol for five weeks. The collected data were analyzed using the Shapiro-Wilk test, Wilcoxon rank sum test, Wilcoxon signed-rank test, t-test and paired t-test using the SAS 9.3 program. The collected EEG data used a frequency series power spectrum analysis method through fast Fourier transform. Results: Significant differences in emotion regulation between the two groups were observed in the anxiety about COVID-19 infection (W = 585.50, p = .002), mood repair of meta-mood (W = 889.50, p = .024), self-regulation ability (t = - 5.02, p < .001), self-regulation mode (t = - 4.74, p < .001), and volitional inhibition mode (t = - 2.61, p = .012). Neurofeedback training for brain homeostasis was effected on enhanced sensory-motor rhythm (S = 177.00, p < .001) and inhibited theta (S = - 166.00, p < .001). Conclusion: The results demonstrate the potential of EEG biofeedback training as an independent nursing intervention that can markedly improve anxiety, mood-repair, and self-regulation ability for emotional distress during the COVID-19 pandemic.

Purpose: This study was conducted to compare the level of depression, self-esteem and mother-adolescent (M-A) communication perceived by both mothers and adolescents between the early adolescent (E-A) group and the late adolescent (L-A) group; and to examine the actor effect and the partner effect of self-esteem and M-A communication on depression in mothers and adolescents. Methods: Participants were 107 Kirogi families who resided in the Midwest region of the U. S. Data were collected from September, 2008 to March, 2009 using the scales of Center for Epidemiologic Studies Depression (CES-D), Self-esteem and Parent-Adolescent Communication Inventory. Results: Mothers in E-A group reported higher scores on depression than mothers in L-A group. Adolescents in L-A group reported higher scores on depression and lower scores on self-esteem than adolescents in E-A group. In the E-A group, mothers' selfesteem had big actor effect on mothers' depression and partner effect on adolescents' depression. In the L-A group, selfesteem of mothers and adolescents had actor effect on their depression respectively without partner effect. M-A communication of mothers influences mothers' depression negatively and adolescents' depression positively. In both group, M-A communication influences their depression with mediating effect of self-esteem. Conclusion: To promote Kirogi families' mental health, programs for mothers and adolescents should be developed differently according to adolescents' development stage.

Purpose: The aim of this study was to analyze the effects of neurofeedback training for reducing stress and enhancing self-regulation in late adolescence to identify the possibility of use for nursing intervention. Methods: A nonequivalent control group pre-post quasi-experimental design was used. Participants were 78 late adolescents assigned to the experimental group (n=39) that received the neurofeedback training and the control group (n=39). Data were collected on heart rate variability (HRV) and skin conductance level (SCL) to assess stress-biomarker response. The questionnaire contained 164 items from: Positive and Negative Affect Schedule (PANAS), Symptom Checklist-90-Revised (SCL-90-R) and Self-regulatory Ability scale. The neurofeedback training was based on the general adaptation syndrome and body-mind medicine. The intervention was conducted in a total of 10 sessions for 30 minutes per session with high-beta, theta and sensory motor rhythm training on scalp at central zero. Results: There were significant difference in standard deviation of normal to normal interval (p=.036) in HRV and SCL (p=.029) of stress-biomarker response between the two groups. Negative affect (p=.036) in PANAS and obsessive compulsive (p=.023) and depression (p<.001) in SCL-90-R were statistically significant. Self-regulation mode (p=.004) in self-regulation ability scale showed a significant difference between the two groups. Conclusion: The results indicated that the neurofeedback training is effective in stress-biomarkers, psychoemotional stress response and self-regulation. Therefore, neurofeedback training using neuroscientific approach based on brain-mind-body model can be used as an effective nursing intervention for late adolescents in clinics and communities for effective stress responses.

The purpose of this study was to identify intrapsychic processes of self socialization in sex role development during late childhood and adolescence. For this purpose I investigated the sex-role stereotypes, sex-role ideology, sex-role identity, and self-esteem of 6th, 8th, and 10th graders and examined the causal relationships among these sex-role variables. Data were gathered through questionnaires administered twice with an interval of three months. The methods of analysis were one-way ANOVA, $x^2$, and multiple regression. The results showed, (1) Adolescents' sex-role stereotypes had significant relationships with sex typing. Subjects with low scores on sex-role stereotypes were more likely to show opposite sex typing. (2) Sex-role ideologies had significant relationships with sex typing. As Subjects agreed more with egalitarianism, they were more likely to exhibit opposite sex typing. (3) Adolescents' sex typing had significant relationships with their self-esteem. The androgynous group exhibited the highest scores on self-esteem. (4) Path analysis from the multiple regression analysis indicated different processes between sexes in sex-role development. In the boys' sex-role development, it was found that only masculinity contributed to self -esteem. Girls' masculinity also contributed most to self -esteem, but other sex -role variables such as femininity and sex-role stereotypes made some contributions to girls' self-esteem.

As interest in adolescent and children's health risks increases, there is an increase in subscriptions to indemnity private health insurance. The purpose of this study was to investigate determinants of purchasing indemnity private health insurance. We conducted panel logit regression analysis on the sample of 4,567 adolescent and children using Korean Health Panel data from 2009 to 2015. As a result, it was analyzed that the participation of private health insurance for children and adolescents was affected not only by the characteristics of children and adolescents (age, birth order, residence, disability) but also by the characteristics of father (indemnity, disability, chronic disease) and mother (age difference between her and her children, indemnity, unmet needs) and the economic level of households (income). In views of this study, it is necessary to continuously implement policies to strengthen the healthcare of children and adolescents in order to alleviate the anxiety about the health risks of children and the burden of medical expenses caused by late marriages and maternal births. In particular, it is necessary to consider policies for multi-child families and vulnerable classes.

This study was designed to investigate the problems facecl by adolescents who have nephrotic syndrome and who have struggled with their disease over a long time. Information obtained from this study can be utilized as basic data in planning nursing care for these adolescents. The subjects in this study were 13 adolescents who were being treated in the pediatric OPD of one general hospital in Seoul. The treatment period ranged from 2 to 15 years. The tool for this study was constructed after asking patients with nephrotic syndrome about their problems using anunstructured questionalire. Problem items which were observed during nursing cared in the pediatric unit. were also inclucled. Ten problem items were constructed on the basis of Moonlcy's problem check list and two additional items related to diet and physical activity were added to the list. The results of this study can be summerized as follows : adolescents with Nephrotic Syndrome. 1) have a vague knowledge about their illness and have distorted concepts. 2) feel social isolation within their peer group because of their changed appearance, limited physical activity and special diet regimen. 3) have problesm in heterosexual relationship because of short height in boys and changes in body propotions in girls. 4) think that their personality has changed due to illness. In most cases(8) changes were in a negative direct ion but in two cases they were positive. 5) have problems with scholastic achievement due to physical weakness and school absence. 6) who are in late adolescentce are more realistic and plan for their future taking into consideration their prognosis much more so than do patients who are in early adolescence. 7) have problems in their peer relationships. 8) have limitation their enjoy ment of leisure time. 9) have some conflict with their siblings. 10) think religion is significant and it has and influence on their life.

The purpose of this study was to analyze the internet usage patterns among adolescents and to provide basic data for the development of internet addiction prevention program. The subjects of this study were 1169 students in middle and high school students in Seoul, Korea. Self-administered questionnaires were employed and data were analysed by SPSS 12.0. Major conclusions were as follows: 1. Most of the students were found to be the normal internet users. On the other hand, potential risk group was 8.2% and high risk group was 4.7%. Every students have had an experience of inter use. The 90.6% of the students' households had internet links. The percentage of students who were using internet more than 3 hours a day was 25.7%, and The most popular type of website was entertainment. 2. Male students showed greater percentages of potential risk and high risk group than female students. The students having parents in divorce, remarriage and separation were more likely to be in potential risk group than those having normal parents. The staying alone in home after school and small sleeping time were positively related to high level of internet addiction. 3. The characteristics of the students in potential risk and high risk group were longer duration of the internet use, internet use through the whole week, frequent internet use late at night, frequent use of pornographic site, main purpose of internet use for entertainment and shortage of rest during internet use. This study results had an limitation of generalizing to entire Korean adolescents because the sample of this study was middle and high school students living in Seoul. Future study was needed for the analysis of internet use behavior of the entire Korean adolescents, and for the identification of the accurate predictors for adolescents' internet addiction.
