Fatigue is a state of difficulty maintaining voluntary activity. Cortisol, which is essential for stress regulation, can cause tissue damage when elevated for long periods of time, which is a common problem for office workers in stressful environments. Sleep quality is important for health and cognitive function, while sleep deprivation increases the risk of physical and mental health disorders. Gyrokinesis combines circular, spiral, and wave movements influenced by yoga, tai chi, and ballet to provide a calming effect on the sympathetic nervous system. This study investigated the effects of Gyrokinesis exercise on lower extremity edema, muscle strength, fatigue, and sleep quality in sedentary office workers. Twenty-seven adult women aged 20–40 years were randomly assigned to a Gyrokinesis exercise group (n=14) or a control group (n=13). The exercise group participated in 60-min Gyrokinesis sessions twice a week for 8 weeks, while the control group used elastic compres-sion stockings during their working hours. Results showed a significant decrease in fatigue and an improvement in sleep quality in the exercise group. Cortisol and serotonin levels showed a significant between-group interaction effect, with within-group changes observed only in the exer-cise group. Sleep quality indices improved significantly over time. In con-clusion, Gyrokinesis exercise has the potential to improve physical and psychological well-being in sedentary office workers by positively influ-encing fatigue, sleep quality, and related hormone levels.

Purpose: This study examined the effects of general, occupational, and sleep-related characteristics on sleep quality in firefighters using the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K). Methods: A cross-sectional survey was conducted from August 15 to 31, 2025 among 217 firefighters working in regions C and D. Data were collected using a self-administered online questionnaire. Sleep quality was assessed using the PSQI-K. Differences in sleep quality according to general, occupational, and sleep-related characteristics were analyzed using the chi-square test. Multiple regression analysis was performed to identify factors associated with the PSQI-K total scores. Results: The mean PSQI-K score was 7.37±3.52, and 37.3% of participants were classified as poor sleepers (PSQI-K≥8.5). Significant differences in sleep quality were observed according to educational level, job type, work schedule, experience with sleep-related symptoms, treatment history, and the timing of sleep problem recognition. In the multiple regression analysis, experience of sleep-related symptoms(β=-.482, p<.001) and treatment history (β=-.168, p=.004) were significantly associated with PSQI-K total scores. The overall regression model was statistically significant (F=13.117, p<.001), explaining 38.9% of the variance in sleep quality. Conclusion: Sleep-related symptoms and treatment history were significantly associated with sleep quality in firefighters. These findings suggest that sleep health problems are closely related to sleep quality in firefighters, and highlight the importance of systematic sleep health management in fire service organizations.

This study aimed to determine the extent of sleep quality and its affecting factors among university students. A total of 149 university students were convenience sampled and surveyed using a questionnaire that included the Sleep Quality Scale, Center for Epidemiologic Studies, stress, and smartphone overdependence. Data analyses showed that sleep quality was 24.2 (±13.35). The affecting factors of sleep quality were depression (β=.514, p=.000), stress (β=.203, p=.005), and smartphone overdependence (β=.131, p=.037), which explained 45.4% of sleep quality. Thus, it is essential to provide education on the importance of sleep and proper sleep hygiene, as well as to develop and implement health promotion programs that identify and address the underlying causes of depression, stress, and smartphone overuse, thereby preventing these health-related problems.

This study aims to examine the effects of job demand factors (hazardous exposure, job autonomy, and labor intensity) on the psychological well-being of construction workers, focusing on the mediating role of sleep quality. The construction industry, characterized by irregular work conditions and exposure to multiple risks, poses significant challenges to workers’ physical and mental health. Structural equation modeling (SEM) was applied to empirically analyze the relationships among job demands, sleep quality, and well-being. Data were drawn from the 7th Korean Working Conditions Survey (KWCS, 2023), including 2,694 construction workers. Exploratory and confirmatory factor analyses were conducted to verify reliability and validity. A structural equation model was estimated using AMOS 26.0, and bootstrapping with 2,000 resamples was performed to test the mediating effects. The findings revealed that both hazardous factors and labor intensity had significant effects on sleep quality and well-being, with sleep quality partially mediating these relationships. Job autonomy had a strong positive direct effect on well-being but did not significantly affect sleep quality. High exposure to hazards and intensive labor tended to lower sleep quality, thereby reducing overall well-being. The model showed good fit indices (CFI=0.991, RMSEA=0.028). The study concludes that improving workers’ well-being in the construction industry requires not only reducing hazardous exposure and adjusting labor intensity but also implementing measures to enhance sleep quality. Moreover, job autonomy plays a key role in promoting psychological well-being. Future research should explore longitudinal analyses and the interaction effects between sleep quality and job autonomy.

This study examined the levels of job stress, sleep quality, and depression among firefighters and explored the relationships among these variables. A cross-sectional survey was conducted with 132 firefighters working in Region B. Data were analyzed using descriptive statistics, independent t-tests, one-way ANOVA, and Pearson correlation analysis with SPSS version 29.0. Significant differences were found according to sex for depression (p=0.034), age for job stress (p=0.013), and subjective health status for job stress (p=0.040), sleep quality (p<0.001), and depression (p<0.001). Job stress showed significant positive correlations with sleep quality (r=0.480, p<0.001) and depression (r=0.472, p<0.001), and sleep quality was also significantly correlated with depression (r=0.694, p<0.001). These findings suggest that job stress, sleep quality, and depression are closely interrelated mental health factors among firefighters. Integrated interventions focusing on stress management, sleep improvement, and mental health screening are needed to promote occupational health and organizational stability. This study provides empirical evidence for developing comprehensive mental health management strategies for firefighters.

본 연구는 Neuro Sound Technology(NST)를 이용한 뇌파훈련이 노인의 수면의 질과 정서성향에 미치 는 영향을 분석하기 위한 연구이다. 2022년 9월부터 2022년 11월까지 U시 S노인복지회관에서 데이케어를 받고 있는 70세 이상 노인을 대상으로 중재를 실시하였다. 참여자는 40명(실험군 20, 대조군 20)이었으며. 실험군은 NST훈련을 주 2회, 1회 30분, 총 30회 실시하였다. 중재 전과 후의 요인 분석은 한국뇌과학연구소에서 개발한 뇌 기능분석보고서(BFA)와 설문지(수면양상)를 통하여 비교하였으며, NST훈련을 적용한 집단에서 수면의 질과 정서 성향에서 유의미한 차이를 보였다. 이 결과는 NST를 통한 뇌파훈련이 노인의 수면의 질과 정서성향에 긍정적인 영향을 미치는 것을 나타낸다. 다만 대상자가 U시에 국한되어 있어서 연구결과를 일반화하기 어려우며, 더 많은 실험참여자의 확대가 요구된다.

This study was designed to analyze the effects of brain wave training using Neuro Sound Technology (NST) on the sleep quality and emotional propensity of the elderly. From September 2022 to November 2022, an intervention was conducted on seniors aged 70 or older receiving day care at S Senior Welfare Center in U City. There were 40 participants (20 in the experimental group and 20 in the control group). The experimental group performed NST training twice a week for 30 minutes each, for a total of 30 times. Factor analysis pre and post intervention was compared through the Brain Function Analysis Report (BFA) and questionnaire (sleep pattern) developed by the Korea Neuroscience Research Institute, and significant differences were found in sleep quality and emotional propensity in the group that applied NST training. These results indicate that brain wave training through NST has a positive effect on the sleep quality and emotional propensity of the elderly. However, because the participants are limited to U City, it is difficult to generalize the research results, and expansion of the number of experimental participants is required.

본 연구는 간호대학생의 ADHD 성향, 수면의 질, 대학적응 간의 관계를 파악하고 대학적응의 영향요인을 확인하고 자 수행되었다. 간호대학생 152명을 대상으로 자가보고식 설문을 실시하였으며, SPSS WIN 25.0 프로그램을 사용하여 기술 통계, 상관분석, 다중회귀분석을 실시하였다. 대학적응은 평균 3.31±0.64이었으며 ADHD 성향(r=-.518, p<.001), 수면의 질(r=-.260, p<.001)과 음(-)의 상관관계를 나타내었다. 다중회귀분석 결과, 대학적응의 주요 영향요인은 ADHD 성향(β= -.443, p<.001), 학업수준(β=.312, p<.001), 경제상태(β=.142, p=.032) 순이었으며 설명력은 40.0%이었다. 수면의 질은 대 학적응의 직접적 영향요인은 아니었으나, ADHD 성향과 유의하게 관련되어 있어 대학생활에서 경험하는 집중력·정서조절·피 로 누적과 같은 간접적 어려움을 심화시킬 가능성이 있다. 따라서 간호대학생의 대학적응 향상을 위해서는 ADHD 성향을 고 려한 심리·학업 지원과 더불어 수면의 질을 개선할 수 있는 생활습관 교육과 환경적 지원이 병행될 필요가 있다.

This study aimed to examine the relationships among ADHD symptoms, sleep quality, and college adjustment in nursing students, and to identify factors influencing college adjustment. Self-administered questionnaires were completed by 152 nursing students, and data were analyzed using SPSS WIN 25.0 with descriptive statistics, correlation analysis, and multiple regression analysis. The mean score of college adjustment was 3.31±0.64, and it showed negative correlations with ADHD symptoms (r=-.518, p<.001) and sleep quality (r=-.260, p<.001). Multiple regression analysis revealed that the major predictors of college adjustment were ADHD symptoms (β=-.443, p<.001), academic level (β=.312, p<.001), and economic status (β= .142, p=.032), explaining 40.0% of the variance. Although sleep quality was not a direct predictor of college adjustment, it was significantly associated with ADHD symptoms, suggesting that difficulties related to attention, emotional regulation, and accumulated fatigue may indirectly affect college life. These findings highlight the need for psychological and academic support tailored to ADHD-related characteristics, along with educational and environmental strategies to improve sleep quality, to enhance college adjustment among nursing students.

Purpose : This study aimed to build and test a path model to explain the factors and paths influencing pilots’ fatigue. The goal was to develop a Korean-style fatigue management model for pilots and propose management plans suited for South Korea’s circumstances. Methods : The survey was conducted with pilots who were members of the Airline Pilots Association of Korea and working for a domestic airline. The questionnaire included items on their general characteristics, job-related factors, psychosocial factors (Type A Behavior and self-esteem), occupational stress, sleep quality, and fatigue. The data were collected through an online survey conducted from September 9 to October 9, 2015. Results : The path analysis results showed that a higher tendency toward Type A Behavior and lower self-esteem were associated with higher occupational stress (β=.961, p<.05). Higher occupational stress resulted in lower sleep quality (β=.699, p<.001) and higher fatigue (β=.489, p<.001). Lower sleep quality also led to higher fatigue (β=.185, p<.05). Conclusion : Pilots often experience fatigue due to the nature of their work, which is difficult to avoid. Therefore, programs to reduce or manage pilots’ fatigue need to be developed. It is essential to establish systems at the policy level to address this issue. Intervention programs should also be applied at both the individual level, focusing on managing psychosocial factors, and the organizational level, addressing occupational stress. These interventions should align with the organizational culture of South Korea.

이 연구는 현대 사회에서 자가 건강관리(Self-care) 및 스마트 헬스케어에 대한 관심이 증대됨에 따라, 스트레스 노출이 빈번한 여자 대학생을 대상으로 이들의 수면의 질과 운동중독 정도를파악하고 두 변인 간의 차이를 분석함으로써 올바른 운동 습관 형성 및 수면 건강 증진을 위한기초 자료를 제공하고자 하였다. 전라남도 D대학교에 재학생 중인 여학생 12명을 대상으로 편의표집을 실시하였다. 수면의 질은 PSQI(Pittsburgh Sleep Quality Index)를 사용하였고, 운동중독및 의존도는 EAI(Exercise Addiction Inventory), EAQ(Exercise Addiction Questionnaire), EDS-R(Exercise Dependence Scale-Revised)을 사용하여 측정하였다. 수집된 자료는 SPSS 29.0을 활용하여 기술통계 및 독립표본 t-검정(Independent t-test)을 실시하였다. 분석 결과, 수면의 질에 따른 운동중독(EAI, EAQ) 및 운동 의존(EDS-R)에서 통계적으로 유의한 차이가 나타나지 않았다. 연구 대상자들은 수면의 질이 좋은 집단(Good group)과 낮은 집단(Poor group) 모두에서 유사한 수준의 운동중독 및 의존 경향을 보였다. 이 연구에서 두 변인 간의 유의한 차이가나타나지 않은 것은 소수의 대상자 수로 인한 통계적 검증력의 한계일 수 있으나, 생리학적·심리학적 기전 관점에서 운동이 수면을 개선하는 긍정적 효과(상승 기제)와 운동중독의 병리적 부작용(교감신경 과활성화 및 코티솔 수치 상승)이 서로 상충(Trade-off) 혹은 상쇄(Cancel out)되었을가능성을 시사한다. 따라서 향후 연구에서는 표본 크기를 확대하고 다양한 심리적·행동적 변인을 포함한 다변량 분석을 통해 운동중독과 수면 건강 간의 보다 명확한 인과관계를 규명할 필요가있다.

This study was analyzed to explore the relationship between sleep quality and exercise addiction among female college students. While the results showed no statistically significant differences, several important academic implications were identified. The lack of significance may be attributed to limited statistical power due to the small sample size (N=12). However, from a physiological and psychological perspective, these findings suggest a potential trade-off or cancel-out effect. This effect occurs between the positive impact of exercise on sleep(sleep promotion mechanism) and the pathological side effects of exercise addiction, such as sympathetic overactivation and elevated cortisol levels. In conclusion, this research indicates that exercise addiction is influenced by complex socio-psychological factors rather than simple physiological sleep conditions. Therefore, future studies should increase sample sizes and employ multivariate analysis, including various psychological and behavioral variables, to clarify the definitive causal relationship between exercise addiction and sleep health.

본 연구는 청소년의 스트레스 정도에 따른 수면충족감 영향 요인을 분석하고자 하였다. 연구 대상자는 2024년 청소년 온라인 건강행태조사 대상자인 54,653명으로 스트레스를 적게 받은 대상자는 31,611명이었고 스 트레스를 많이 받은 대상자는 23,042명이었다. 자료 분석은 IBM SPSS ver. 27.0 프로그램을 이용하여 가중치를 부여하여 분석하였다. 분석 결과, 스트레스가 낮은 군에서는 흡연이 수면충족감을 낮추었으며, 주관적 신체상이 비만인 경우, 슬픔과 절망감을 경험하는 경우 더 낮은 수면충족감을 보고하였다. 스트레스가 높은 군에서는 성적이 높은 학생들의 수면충족감이 더 낮았으며, 외로움이 낮은 경우 수면충족감이 더 높은 결과를 보였다. 이러한 스트 레스 수준별 차이를 바탕으로 스트레스가 낮은 청소년은 개인의 건강행동 수정과 심리적 안정 증진을 위한 개별적 접근이 필요하고 스트레스가 높은 청소년은 학업 부담완화와 사회적 지지체계 강화를 통한 환경적 접근이 필요함 을 알 수 있다. 따라서 청소년의 수면의 질 증진을 위해 개별화된 중재 프로그램 개발이 중요하다.

This study analyzed factors influencing sleep satisfaction by stress levels. Of the 54,653 participants, 31,611 reported low stress and 23,042 reported high stress. Weighted analyses were performed using IBM SPSS 27.0. Results revealed distinct patterns: low-stress adolescents showed decreased sleep satisfaction with smoking, obesity perception, and feelings of sadness/despair, while high-stress adolescents with higher academic performance reported poorer sleep satisfaction, though lower loneliness improved it. These differential patterns indicate that low-stress adolescents require individualized health behavior interventions, whereas high-stress adolescents benefit from environmental approaches addressing academic pressure and social support. Tailored intervention programs are essential for optimizing adolescent sleep quality.

This study evaluates the potential effects of the Ceragem spinal thermal massage device on sleep quality and analyzes how its thermal and mechanical massage stimuli influence physiological responses. Clinical studies and case reports suggest that the device’s thermal stimulation may help regulate the autonomic nervous system, reduce stress and pain, and potentially improve sleep quality. Additionally, mechanical massage may induce muscle relaxation and stabilize the nervous system, contributing to overall body relaxation. Electromyography (EMG) results indicate that mechanical stimulation may reduce muscle tension and help recalibrate autonomic balance. In conclusion, the Ceragem device shows promise as a non-pharmacological tool for improving sleep quality, though further systematic and rigorous research is needed.

본 연구는 간호대학생의 스마트폰 중독과 주간 졸음 정도를 파악하고, 스마트폰 중독이 주간 졸음에 미 치는 영향을 파악하기 위한 서술적 상관관계 연구이다. 간호대학생을 편의 표집하여 스마트폰 중독, 우울, 수면의 질, 주간 졸음 등이 포함된 설문지를 이용하여 조사하였다. 187명의 자료를 분석한 결과 스마트폰 중독은 24.6%이 었으며, 수면의 질은 22.4(±11.97)점, 주간 졸음 점수는 6.2(±3.20)점으로 주간 졸음증은 13.9%였다. 주간 졸음에 영향을 미치는 변수는 수면의 질(β=.44 p=.000)과 스마트폰 중독(β=.17, p=.010)으로 나타나 주간 졸음의 22.5%를 설명하였다 그러므로 간호대학생의 수면 건강을 증진하기 위해 건강한 스마트폰 사용 가이드를 포함한 수면 위생 교육 프로그램의 개발 및 운영, 그리고 상담 프로그램의 활성화가 필요하다.

The purpose of the study was to determine the extent of smartphone addiction and daytime sleepiness and the effect of smartphone addiction on daytime sleepiness among nursing students. A total of 187 nursing students were convenience sampled and surveyed using a questionnaire that included smartphone addiction, depression, sleep quality, and daytime sleepiness. Data analyses showed that the prevalence of smartphone addiction was 24.6%, sleep quality was 22.4 (±11.97), daytime sleepiness was 6.2 (±3.20), and the prevalence of excessive daytime sleepiness was 13.9%. The variables affecting daytime sleepiness were sleep quality (β =.44, p=.000) and smartphone addiction (β=.17, p=.010), which explained 22.5% of daytime sleepiness. Therefore, the development and implementation of sleep hygiene education programs, including guidelines for healthy smartphone use, and the activation of counseling programs are needed to promote sleep health among nursing students.

Purpose: This study was conducted to examine the association between energy drink consumption and sleep duration and quality among Korean high school students. Methods: Data on 24,760 high school students were obtained from the 15th Korea Youth Risk Behavior Survey. The association between energy drinks consumption and sleep duration and quality was analyzed by multivariate logistic regression analysis in consideration of the complex sampling design. Results: 33.8% of respondents reported that they had at least one energy drinks in the past week. The majority (95.2%) of all subjects reported that the average sleep duration was less than 8 hours per day, and 84.7% of them were dissatisfied with sleep quality. After adjusting for confounding factors, higher energy drinks consumption was significantly associated with short sleep duration (< 8 hours/day) and unsatisfactory sleep quality. Conclusion: Insufficient sleep and poor sleep quality caused by energy drinks consumption can adversely affect the healthy development and functioning of high school students. Therefore, health education on the dangers of energy drinks and healthy sleep is needed, and it is urgent to prepare policies that can be realized at the national level.

Purpose: The purpose of this study was to review articles that used the Pittsburgh Sleep Quality Index (PSQI) scale to measure sleep quality among adults with trauma experiences. Methods: Databases such as PubMed, CINAHL, Embase, Cochrane, Medline, Google Scholar, Riss, NDSL, and reference data were searched systematically for relevant studies from July 5 to 6, 2018. A quality assessment was conducted using the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) risk of bias checklist, including content validity, structural validity, internal consistency, reliability, measurement error, hypotheses testing, cross-cultural validity, criterion validity, and responsiveness. Results: Fourteen studies met the inclusion criteria. All selected studies confirmed the overall quality of sleep by total score, but only 28.6% of the papers presented subscales. The quality of the methodology used varied within and between studies. Internal consistency of 21.5%, cross-cultural validity of 7.1%, and criterion validity of 14.2% were all evaluated as sufficient (+). Reliability and measurement errors were not presented in selected studies. Conclusion: Our findings revealed that overall quality of sleep was measured by analyzing the characteristics and measurement attributes of the PSQI. However, as a result of the varying purposes of each study, the full potential of the tool could not be optimized. Future research should assess the attributes of the PSQI based on the content specified in the COSMIN evaluation standard, using it carefully to consider the target population’s socio-cultural characteristics.
