Purpose: The rising prevalence of smartphone overdependence among adolescents and its detrimental impact on mental health have become a growing concern. This study aimed to investigate the association between smartphone overdependence and the mental health of Korean adolescents. Methods: Participants were drawn from the 16th Korea Youth Risk Behavior Web-based Survey conducted in 2020. The dependent variable as smartphone overdependence, while the main exposure of interest was mental health, encompassing generalized anxiety disorder (GAD), perceived stress, sources of perceived stress, perceived loneliness, and perceived depressive symptoms. The study employed the Rao-Scott chi-square test and multiple logistic regression using IBM SPSS version 26.0. Results: The participants comprised 54,948 adolescents aged 13 to 18 years. Among them, 25.1% (n=13,775) were categorized as smartphone overdependence group. Specifically, 20.3% of adolescents who reported GAD ≥10 and 22.5% of those who reported experiencing high levels of perceived loneliness were identified as smartphone overdependent. The GAD increased a risk of smartphone overdependence by 2.61 times (95% confidence interval [95% CI]: 2.46-2.77). Perceived loneliness was associated with 1.98-fold (95% CI: 1.87-2.09) increased risk of smartphone overdependence. Additionally, conflict with peers was found to increase the risk of smartphone overdependence by 4.63-fold (95% CI: 3.89-5.52), followed by conflict with parents (odds ratio [OR]: 4.52, 95% CI: 3.84-5.31), and family environment (OR: 4.52, 95% CI: 3.75-5.46). Conclusion: The findings underscore a significant association between smartphone overdependence and mental health in Korean adolescents. Healthcare services to improve their emotional coping and interpersonal skills are necessary.

Objective: The objective of this study was to investigate the effect of 20-day litter weight on behavior and heart rate variability (HRV) of piglets under stress. Methods: Forty four original litters were categorized as high litter weight (HW) litters (n = 22) and low litter weight (LW) litters (n = 22) by 20-day litter weight. From each original HW litter, three males and three females were randomly selected after weaning and the 12 piglets from two original litters with similar age of days were regrouped into one new high litter weight (NHW) litter (11 NHW litters in total). The original LW litters were treated with a same program, so that there were 11 new low litter weight (NLW) litters as well. The latencies to first fighting, fighting frequencies and duration within three hours were recorded after regrouping and the lesions on body surface within 48 hours were scored. Besides, HR (heart rate, bpm, beats per minute) and activity count (ACT), time domain indexes and frequency domain indexes of the piglets were measured in an isolation trial to analyze the discrepancy in coping with stress between the original HW and LW litters. Results: The results exhibited that piglets from the HW litters launched fighting sooner and got statistically higher skin lesion score than those from the LW litters (p = 0.03 and 0.02, respectively). Regarding the HRV detection, compared with the HW litters, the LW litters exhibited a lower mean HR (p<0.05). In the isolation test, a highly significant higher ACT value was observed between the HW litters, compared to the LW litters (p<0.01). Significant differences were observed in standard deviation of R-R intervals, standard deviation of all normal to normal intervals, and most frequency-domain indicators: very low-frequency, low-frequency, and high frequency between the HW and LW litters as well. The difference in LF:HF was not significant (p = 0.779). Conclusion: This study suggests that compared with litters of low 20-day litter weights, litters with higher 20-day litter weight take more positive strategies to cope with stress and have stronger HRV regulation capacity; HW litters demonstrate better anti-stress and adaptation capacity in the case of regrouping and isolation.

Alcoholism affects not only the individuals who depend on it, but also their families. Children who have an alcohol dependent parent have various problems and need help, but little attention has been given to them. Many references report only negative characteristics of these children. In order to help the children of alcohol dependent parents, health professionals need more information. A wholistic understanding and analysis of these children is needed as a basis for the development of suitable programs of help them. A phenomenological methodology was used to identify the experience of children whose fathers were addicted to alcohol. The findings portray the essence of the lived experience of children of alcohol dependent fathers. Nine adolescents participated in in-depth inverviews and observation with the researcher, done between October and December 2001. The data were recorded on audio tape and transcribed. Sampling was continued until the data were theorectically saturated. The Colaizzi's method was used for data analysis. The results of this study are as follows. Three themes and twenty six meanings were identified. The first theme is Living Alone: living abusively as partner to an alcohol dependent father, living dangerously like an explosive fury, living as an object that ha no self, living with rejection of fatherly being, living with felt responsibility but having no power to help mother who suffers patiently with pain and abuse, living along with no shoulder to lean on, and living with the prejudice of sex discrimination. The second theme is Paradoxical Coping in Life. The meanings are obsessive behavior as a way to control father's behavior, always on the defensive due to anxiety and tension, being afraid of life alone due to paranoid thoughts, contradictory expectation about father's drinking behavior due to life with chronic tension, stress becoming familiar and life being boring and tendious without stimulation, life that is fake and filled with misinterpretations about reality, affection sought from others due to loneliness, compensatory life within peer group, negative expectation about the future due to negative experiences, controling others to protect ego, denial of real emotion to protect self from hurt, life of regretting self, and strong need for approval from others. The third theme is sustaining life. The meanings are ambivalence between revenge on father and pity, struggle for desirable self against fear of gather-like image, understanding father through self reflection, hope to find fatherly being through father's recovery, being able to stand through emotional control and cognitive restructuring, nurturing the seed of hope for the future while in a situation of desperation. The contribution of this study is to give a wholistic understanding of the empirical reality of children of alcohol dependent parents and to develop substantive theory in nursing knowledge. In nursing practice, the results of this study can provide a foundation for the development of programs for children of alcohol dependent parents.

Purpose: The role of sex role identity types and health promoting behaviors in relation to premenstrual symptoms and interrelatedness among the three variables were examined. Methods: A cross sectional descriptive study was employed with 327 female university students. KSRI, HPLP, and MDQ were used as measurement tools. Results: Four types of sex role identities were classified; undifferentiated(33.7%), androgyny (32.7%), masculinity(16.8%), and femininity(16.8%) in order. Premenstrual symptoms(F=3.11, p= .027) and health promoting behaviors(F=12.74, p= .000) were significantly different by sex role identity types. As determinants of premenstrual symptoms, health promoting behaviors for all subjects, stress coping for the feminine type, and interpersonal relationships for the undifferentiated type were identified. In discriminating between the feminine type and undifferentiated type, premenstrual symptoms and self responsibility were shown as significant factors. Conclusion: Interrelatedness among sex role identity, health promoting behaviors and premenstrual symptoms imply the importance of a psychosocial aspect in premenstrual symptoms. Therefore, these three variables should be applied more specifically for nursing assessment and management of women having premenstrual symptoms.

The present experiment was designed to investigate the effects of behavioral, response to immune function in response to electric footshock in mice. Mice were subjected to electric footshock for 3 days(two sessions a day, 11 times of shock for about 31 minutes a session). The humoral immune response was measured using mice immunized with rat RBC. The cell-mediated immune responses were evaluated by contact hypersensitivity to 2, 4-dinitrofluorobenzene(DNFB) and by phytohemagglutin(PHA)-stimulated splenocytes proliferation assay. In stressed group, electric footshock suppressed significantly anti-rat RBC antibody production(p<0.05), but enhanced significantly $T_{48}$ relative to $T_{24}$ in contact hypersenstivry (P<.01) and T-cell proliferation response(P<.05) by PHA stimulation elative to control group. T-cell proliferation response by PHA stimulation was significantly correlated to the movement than the sensitivity and coping behavior in the mouse, in response to the electric footshock. These data supper the importance of behavioral response in stress-induced changes of immune functions.

본 연구에서는 사회적 불안이 개인의 심리적 적응에 미치는 영향을 살펴보았다. 사회적 불안을 더 많이 느끼는 사람들이 적게 느끼는 사람들에 비하여 걱정증상과 신경증 수준이 높았고 삶의 만족도와 심리적 안녕감 수준은 낮았다. 사회적 불안의 하위 영역과 하위 차원 중 심리적 적응도를 예언하는 영역이나 차원이 무엇인지를 알아보았다. 부정적 적응은 주로 개인불안에 의해 유발되는 반면, 긍정적인 적응은 개인불안과 함께, 공정성불안과 미래불안에 의해 예측되었다. 또한 사회적 불안 하위 차원 중에서는 상황을 염려하여 사람들이 느끼는 불안인 예견불안이 긍정적, 부정적 적응도를 유의하게 예언하였다. 사회적 불안과 최근 발생한 응답자들의 행동이나 생각 변화와의 관계를 분석한 결과, 사회적 불안이 높은 응답자일수록 최근 공격반응이나 포기반응을 더 자주 하였다. 특히 공격반응의 경우 개인불안이 유의한 예측변수로 나타났으며, 포기반응의 경우에는 정치불안과 사회문제불안이 유의한 예언변수로 나타났다. 사회적 불안차원 중에서 공격과 포기반응을 예측하는 변인은 예견불안이었다. 마지막으로 사회적 불안에 대한 스트레스 대처방식을 살펴본 결과, 응답자들은 전반적으로 문제해결적 대처방식을 많이 사용하고 있었다. 그러나 사회적 불안 수준이 높은 사람들이 사회적 불안이 낮은 사람들에 비하여 소망적 사고를 많이 하고 있었고, 특히, 안전불안과 정치불안을 많이 느끼는 사람일수록 소망적 사고를 많이 하였다. 반면에 반응불안이 높은 사람은 문제 회피적인 스트레스 대처방식을 많이 사용하고 있었다.

The basal ganglia network has been implicated in the control of adaptive behavior, possibly by integrating motor learning and motivational processes. Both positive and negative reinforcement appear to shape our behavioral adaptation by modulating the function of the basal ganglia. Here, we examined a transgenic mouse line (G2CT) in which synaptic transmissions onto the medium spiny neurons (MSNs) of the basal ganglia are depressed. We found that the level of collaterals from direct pathway MSNs in the external segment of the globus pallidus (GPe) ('bridging collaterals') was decreased in these mice, and this was accompanied by behavioral inhibition under stress. Furthermore, additional manipulations that could further decrease or restore the level of the bridging collaterals resulted in an increase in behavioral inhibition or active behavior in the G2CT mice, respectively. Collectively, our data indicate that the striatum of the basal ganglia network integrates negative emotions and controls appropriate coping responses in which the bridging collateral connections in the GPe play a critical regulatory role.

Objectives: Anxiety disorders are the most common psychiatric disorders in adolescents and seem to occur the earliest among all forms of psychopathology. The aim of this study was to investigate the association of anxiety severity with health risk behaviors and mental health in adolescents. Methods: Data from the 2020 Korean Youth Risk Behavior Web-Based Survey were analyzed. A total of 54948 adolescents responded to the 7-item Generalized Anxiety Disorder Scale (GAD-7) for the assessment of their anxiety severity as well as to the mental health and health risk behavior survey. Logistic regression analysis, t tests, and variance analysis of a complex sample general linear model were used to examine the association of anxiety severity with health behaviors and mental health. Results: After statistical adjustment for sociodemographic characteristics, the subjects in the severe anxiety group were significantly more likely to be current smokers (odds ratio [OR]: 2.08, 95% confidence interval [CI]: 1.72-2.50), current drinkers (OR: 1.91, 95% CI: 1.67-2.19), experience habitual substance use (OR: 10.89, 95% CI: 8.22-14.42), have sexual intercourse (OR: 2.10, 95% CI: 1.76-2.51), and have unprotected intercourse (OR: 2.21, 95% CI: 1.67-2.92) than those in the normal group. Anxiety severity negatively correlated with sleep satisfaction and happiness, but positively correlated with stress perception, loneliness, depressive symptoms, and suicidality. Conclusion: Adolescent anxiety is associated with health risk behaviors and poor mental health. Thus, early screening and intervention for anxiety in adolescents could contribute to the management and coping of youth health risk behaviors in the community.
