Purpose: This study was conducted to define the concept of stress in siblings of childhood cancer patients. Methods: The hybrid model was used to perform the concept analysis of stress in childhood cancer patients' siblings. Through reviews of 16 studies in the theoretical phase and interviews with 20 siblings in the field phase, the derived results were brought together in the integration phase. Results: The concept of stress in siblings of patients with childhood cancer was found to have 6 attributes and 28 indicators in 3 domains. Personal factors included 2 attributes (fear about childhood cancer and immature coping skills), and family factors had 2 attributes (changes in relationships with family and changes in family environment), social factors had 2 attributes (changes in relationships with friends and in the school experience, and insufficient social support). Conclusion: The stress of siblings of childhood cancer patients was defined as a state of tension associated with personal, family, social factors that can be related to their siblings' childhood cancer. The findings in this study provide the base for the development of a tool for measuring siblings' stress and/or the development of nursing programs for these siblings.

Purpose: To compare the effects of the Interaction Model of Client Health Behavior (IMCHB)-based oral health program (OHP) and walking exercise program (WEP) on oral health behaviors, periodontal disease, physical activity, and psychological indicators (depression, stress, and quality of life) in pregnant women. Methods: A nonequivalent control group pretest-posttest design was adopted to compare the effects of a 12-week OHP and WEP on pregnant women (n=65). Pregnant women were randomly assigned to the oral health group (OHG; n=23), walking exercise group (WEG; n=21), or control group (CG; n=21). Data were analyzed by the ${\chi}^2-test$, Fisher's exact test, Scheffe test, and repeated measures ANOVA, using the Statistical Package for the Social Sciences for Windows (version 21.0). Results: The OHG and WEG showed significant improvements in oral health behaviors, periodontal disease, and psychological indicators as compared to the CG. The WEG showed significant improvement in physical activity as compared to the OHG and CG. Conclusion: These findings indicate that the IMCHB-based OHP and WEP were effective in improving periodontal disease, physical activity, and psychological indicators. However, further studies are needed to identify the positive effects of the OHP and WEP on birth outcomes.

The correlation between the Military Service Adaptation Test and the Biometric Index is studied herein with the aim of preventing military safety accidents. The subjects were 36 soldiers under the age of 25 years. Based on the results of the service adaptation test, the soldiers who did not adapt to the service were distinguished. First, there was a significant difference in brain stress among the brain wave indicators of the general group and the group of interest. Second, the higher the left and right brain imbalance index among the brain wave indicators, the higher was the level of empathy shown by the subjects. Third, among the pulse indicators, the subjects with high cumulative fatigue levels were found to have high levels of emotion (anxiety, depression, physicalization) and relationship isolation (indifference, sensitivity). Based on these results, the implications of this study and suggestions for future research are discussed.

This study aims to investigate the effect of frequency of using forest environment on workers' stress. Workers in medical and counseling industry, which is recently known to require heavy emotional burden and thus cause a lot of stress and burnout syndrome, participated in the study. We classified 370 subjects, who were working at medical and counseling service institutions in Seoul metropolitan area, into two groups according to frequency of using forest environment by conducting a screening survey. 69 subjects submitted written consent and were recruited for either forest therapy program or control-group test; the "high" group (n=27) at the high frequency of using forest environment and the "low" group (n=42) at the low level. We measured the level of stress by using psychosocial indicators such as Worker's Stress Response Inventory (WSRI), Recovery Experience Questionnaire (REQ), and Maslach Burnout Inventory-General Survey (MBI-GS) and biological ones such as heart rate variability (HRV), cortisol, and Natural Killer cell (NK cell). The results suggested that the level of stress differed by frequency. The "high" group showed significantly low scores in the depression and work sub-scale and the total score of WSRI, emotional exhaustion, professional efficacy and total score of MBI-GS, and high scores in the total score of REQ. Similar tendencies were observed in the most of other indicators of psychosocial measures. Regarding the biological indicators, the "high" group showed the highest SDNN, RMSSD and TP measures of HRV and NK Cell activity and the low cortisol, although the statistical power did not reach the significant level. Our results suggest that the subjects who use forest environment frequently show favorable stress level both psychologically and biologically.

Financial soundness in the household sector matters for financial stability and for the real economy. The level of household debt in Korea raises concern about the financial soundness of the household sector due to its size, growth rate and quality. Against this backdrop, we assess the financial vulnerability of borrowers based on an analysis of credit bureau (CB) data, in which the actual credit activities of most individuals are recorded at a high frequency in Korea. We construct over-indebtedness indicators from the CB data and then assess the predictability of forthcoming defaults. Based on the over-indebtedness indicators, we show how borrowers are distributed in terms of over-indebtedness and how the over-indebted differ from average borrowers in terms of their characteristics. Furthermore, we show how the aggregate credit risk in the household sector would change under macroeconomic distress by analyzing how each borrower's credit quality would be affected by adverse shocks. The findings of this paper may contribute to assessing household debt vulnerability and to enhancing regulatory and supervisory practices for financial stability.

A fatigue damage accumulation model based on the continuum damage mechanics theory was develope(1 where modules decay ratios in tension and shear on used as indicators for damage variables D . In the model, the damage variables are considered to be second-order tensors. Then the maximum principal damage variable, $D^*$ is introduced According to the similarity to the Principal stress, $D^*$ is obtained as the maximum eigen value of damage tensor [D']. Under proportional tension and torsion loadings, fatigue lives were satisfactorily predicted at any combined stress ratios using the present model in which the fatigue characteristics only under uniaxial tension and pure torsion loadings on needed. Fatigue life prediction under uniaxial tension and pure torsion loadings, was performed based on the damage mechanics using boundary element method.

The Unfolded Protein Response (UPR) serves as a critical cellular mechanism dedicated to maintaining protein homeostasis, primarily within the endoplasmic reticulum (ER). This pathway diligently responds to a variety of intracellular indicators of ER stress with the objective of reinstating balance by diminishing the accumulation of unfolded proteins, amplifying the ER's folding capacity, and eliminating slow-folding proteins. Prolonged ER stress and UPR irregularities have been linked to a range of neuropsychiatric disorders, including major depressive disorder, bipolar disorder, and schizophrenia. This review offers a comprehensive overview of the UPR pathway, delineating its activation mechanisms and its role in the pathophysiology of neuropsychiatric disorders. It highlights the intricate interplay within the UPR and its profound influence on brain function, synaptic perturbations, and neural developmental processes. Additionally, it explores evolving therapeutic strategies targeting the UPR within the context of these disorders, underscoring the necessity for precision and further research to effective treatments. The research findings presented in this work underscore the promising potential of UPR-focused therapeutic approaches to address the complex landscape of neuropsychiatric disorders, giving rise to optimism for improving outcomes for individuals facing these complex conditions.

Purpose: This study was performed to systematically review the recently published nursing intervention studies. Methods: The literature was identified through the Korean Education and Research Information Service (KERIS), the Korean Information Service System (KISS), and National Assembly Library websites. Key words such as breast cancer, nursing, and intervention were used. The factors analyzed are as follows: 1) the characteristics of studies and study populations, 2) the classification of interventions, 3) outcome indicators and their effects, and 4) effective interventions. Results: Thirty two studies were included. Seventeen studies used a single intervention such as aerobic dance, TaiChi, foot massage, aromatherapy, or a stress-reduction method. Fifteen studies used combined interventions, including education, exercise, counseling, support, yoga or meditation. The data on 47 outcome indicators and their effects were segregated into psycho/spiritual outcomes, stress coping, physical outcomes, cardiorespiratory function, symptom management, arm and shoulder functions, fatigue, and quality of life. Some interventions had positive effects on stress, fatigue, and functions of shoulder. Conclusion: Various interventions are available for breast cancer patients, and some have had positive effects. However, more studies are required to develop evidence-based practice guidelines for nursing interventions.

Objective: The purpose of this study was to explore the mediating effects of parenting efficacy on the relationship between parenting alliance and parenting stress, and to investigate whether the relationships between these indicators were the same for mothers and fathers. Methods: A sample of 228 parents (114 mothers and 114 fathers) of 6 month old infants in Gyeonggi Province completed measures of Perceived Parenting Competence, Parenting Alliance Inventory, and Parenting Stress Inventory-Short Form. Results: The results indicated that parenting alliance produced its effect directly and indirectly through parenting efficacy on parenting stress. Using multiple group SEM analyses, it revealed that fathers parenting efficacy was mediated by parenting alliance and that the strength of the pathways was stronger for fathers than for mothers. Conclusion/Implications: These findings suggest that parenting alliance can improve father's parenting efficacy. The differential predictors of mother and father efficacy as well as their implications for future research are discussed.
