Prior to the emergence of Covid-19, Saudi Arabia (SA) had never faced the challenge of dealing with a global pandemic. Significantly, the current crisis has impacted all industries and sectors in the country, including the healthcare system, and has led to an emphasis on human life being more precious and valuable than economic profit. This study focuses on the impact of Covid-19 on the health of nurses, including their quality of life, during 2020. Understanding the position of the nursing profession during the pandemic, including the most effective methods of preventing work-related stress is important. Information was acquired through an online survey method (i.e. self-completion), known as the Expanded Nursing Stress Scale (ENSS), which was distributed to nurses in all regions of SA. It was found that the main aspects impacting nurses' work-related stress include gender, employment type, training, and dealing with infected patients. In addition, they highlight that such stress plays a substantial role in patient safety and nurses' satisfaction at work, as well as the future survival of organizations. The emergence of Covid-19 as a novel infectious disease has increased nurses' uncertainty and work-related stress. The results of this research will provide insights into the views of both nurses and their managers, in order to identify the main indicators of stress.

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.

본 연구는 산림환경 이용 빈도에 따라 근로자의 스트레스 수준에 어떤 차이가 있는지를 알아보고자 했다. 이를 위해 정서적 스트레스와 소진 경험이 많은 것으로 알려진 감정노동 직업군 중에서 연구대상자를 선정했다. 수도권 소재 의료기관과 상담기관의 직원 370명을 대상으로 사전 설문조사를 실시하여 산림이용 빈도에 따라 이들을 분류했다. 이후 캠프와 대조군 검사에 서면으로 참여의사를 밝힌 인원을 모집한 결과, 최종적으로 산림환경 이용 빈도가 높은 집단이 27명, 산림환경 이용 빈도가 낮은 집단 42명의 총 69명이 연구에 참여하였다. 이들을 대상으로 Worker's Stress Response Inventory (WSRI), Recovery Experience Questionnaire (REQ), Maslach Burnout Inventory-General Survey (MBI-GS)와 같은 심리사회적 변인과 심박변이도(heart rate variability), 코티솔(cortisol), 자연살해세포(Natural Killer cell) 등의 생물학적 변인 검사를 실시한 결과, 산림환경 이용 빈도에 따라 스트레스 수준에 차이가 나타나는 것을 확인할 수 있었다. 산림이용 빈도 "높음" 집단은 우울, 직무증상과 스트레스 반응 총점(WSRI)이 "낮음" 집단에 비해 유의미하게 적었으며, 스트레스에서의 회복경험 총점(REQ) 역시 통계적으로 유의하게 "낮음" 집단보다 높았다. MBI-GS의 정서적 고갈과 직업성취감 감소, 총점에서도 "높음" 집단이 유의하게 낮은 것을 확인할 수 있었다. 대부분의 다른 지표에서도 동일한 경향성이 관찰되었다. 생물학적 변인에서는 통계적으로 유의한 결과는 없었으나 "높음" 집단은 심박변이도의 SDNN 및 RMSSD, TP 지표와 자연살해세포 활성도에서 높은 수치를 나타내었고, 코티솔은 낮았다. 이 결과는 평소 산림환경을 자주 이용하는 사람들이 심리사회적인 스트레스가 낮고, 생물학적으로도 더 스트레스를 적게 받는 상태에 있음을 의미한다.

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.
