Purpose: The purpose of this study was to evaluate the effectiveness of a sleep improvement program combined with an aroma-necklace on sleep, depression, anxiety, and blood pressure in elderly women living at home. Methods: A program consisting of a four-week (one hour per week) sleep improvement intervention plus use of an aroma-necklace, was developed based on Cox's Interaction Model of Client Health Behavior. 70 elderly women were assigned to the experimental (n=35) or control group with no intervention (n=35). Data from 62 participants (32 in the experimental and 30 in the control) were analyzed using the SPSS 21.0 program. Women in the experimental group were instructed to constantly wear the aroma necklace filled with marjoram and orange oil until the program was completed. Sleep quality, sleep duration, sleep satisfaction, depression, anxiety, and blood pressure were measured to identify the effectiveness of the program. Results: Significant group differences were found in sleep quality (t=-5.10, p<.001), sleep duration (z=-3.10, p=.002), sleep satisfaction (z=-4.13, p=<.001), depression (t=2.53, p=.015), and anxiety (z=-2.47, p=.014). No differences were found in the systolic or diastolic blood pressure. Conclusion: The results indicate that a sleep improvement program combined with an aroma-necklace was effective in improving sleep disturbances in elderly women living at home. Nurses may contribute to improving sleep among elderly women by applying this program to aged women living in various environments.

purpose: In addition to evaluating the quality of sleep of college students, the effect on non-face-to-face online learning satisfaction is identified and used as basic data for improving the quality of remote lectures. Methods: From June 1 to June 24, 2022, a self-entry survey was conducted on students enrolled in the dental hygiene department of D University in Daegu. To evaluate the non-face-to-face online learning satisfaction and sleep quality of the study subjects using the lBM SPSS Statistics 21 program, ANOVA analysis was conducted on the difference between individual stress levels and non-face-to-face online learning satisfaction. The correlation between sleep quality, stress, and non-face-to-face online learning satisfaction was analyzed using Pearson's correlation coefficient. Results: The lower the quality of sleep, the higher the stress, resulting in statistically significant results (p<0.001). The higher the quality of sleep, the higher the learning satisfaction, resulting in statistically significant results (p<0.001). There was a statistically significant positive correlation between learning satisfaction and stress (r=0.591, p<0.01). Conciussions: Through the above results, in order to improve the satisfaction of non-face-to-face online learning, it is necessary to manage the individual's learning environment and health to relieve stress. Instructors also need to communicate with learners and apply teaching methods considering learners' academic abilities.

Purpose: The purpose of this exploratory study was to find a specific time of day with a stable cortisol level and to investigate the relationship between salivary cortisol and sleep. Methods: A total of 36 Korean female college students participated in the study. Salivary specimens were collected 6 times a day for 2 days in different stressful situations. Sleep characteristics were measured using an actigraph while salivary specimens were collected. Perceived stress was evaluated using the Global Assessment of Recent Stress. Results: Depending on whether there were morning peak and/or afternoon elevations in the cortisol levels, the type of diurnal cortisol pattern was classified into 4 types. None of the cortisol levels in different times of the day showed significant relationships to perceived stress levels. Cortisol levels in the morning, levels of peak cortisol and diurnal differences of cortisol were significantly correlated with sleep duration. The time with most stable cortisol level was 9-10 pm. Conclusion: It is recommended that measurements of salivary cortisol are taken from 9-10 pm since it showed a stable value regardless of diurnal cortisol rhythm and sleep. Sleep duration should be considered as an important confounding factor in measuring cortisol levels in the morning and the diurnal differences of cortisol.

This study uses the 9th 1st year (2022) National Health and Nutrition Examination Survey to analyze the relationship between sleep time and the number of existing teeth for the adult population aged 19 or older to provide basic data on related dental development. There is a purpose. This program is designed to improve sleep quality and maintain the number of viable teeth in the future. The subjects were 53,220 people who answered the questions. The collected data were analyzed using SPSS (ver 21.0) program using complex samples, and chi-square analysis and logistic return analysis were performed. As a result, it was found that 2.537 times more existing teeth remained when sleep time was 9 hours or more than when sleep time was 6 hours or less, and there was a statistically significant difference. In conclusion, it is necessary to recognize the importance of the number of remaining teeth and to make efforts to manage personal immunity, such as sleep management for adults, and to promote and prevent oral care and oral health education in order to maintain the number of remaining teeth.

Biobehavioral nursing research is focused on generating knowledge that examines relations among biological, behavioral, and social dimensions of health to improve outcomes. In this paper we review the findings of a biobehavioral nursing study of individuals with fibromyalgia (FM) that was framed from the perspective of an individual human response model, the FM literature, and our previous studies in midlife women. We were particularly interested in the studying the role of 'arousal' secondary to pain or to dysregulated hypothalamic-pituitary-adrenal (HPA) axis hormones during sleep and the impact on symptom expression. Unexpectedly, we did not find evidence of, arousal' or abnormal amounts of HPA axis hormones but we did find reduced amounts of growth hormone (GH) and prolactin (PRL) and of sleep spindle activity, a biomarker of sleep maintenance. We discuss these new findings and how our thinking was re-shaped to better understand the role that disturbed sleep plays in symptom expression in FM. It is argued that disturbed sleep maintenance mechanisms coupled with dysregulated somatotrophic-growth hormone axis and sleep-related PRL render individuals vulnerable to the development of or exacerbations of FM symptoms.

Purpose: This study was to examine the effects of foot reflexion massage on sleep disturbance, depression disorder, and the physiological index of the elderly in nursing homes. Method: The research design was a non-equivalent control group pretest-posttest quasi-experimental study. The subjects in this study were 50 elderly people who resided in two different nursing homes in the same region. An experimental group and a control group were organized with 25 subjects respectively, and foot reflexion massage was provided for 12 sessions, 30 minutes per session. The selected dependent variables were sleep disturbance, depression disorder, and physiological indices(blood plasma serotonin, serum cortisol), which were all measured before and after foot reflexion massage was offered. Data analysis included $x^{2}$-test, t-test, paired t-test, and ANCOVA, using the SPSS program package. Result: 1. The experimental group improved sleep quality more than the control group. 2. The experimental group had less depression disorder than the control group. 3. The experimental group had higher serotonin levels than the control group. Conclusion: It's necessary to give foot reflexion massage as a successful nursing intervention to elderly who undergo a change in sleep, and suffer from a depression disorder due to a deterioration in sleep.

Objectives: Aim of present study was designed to investigate the soporific effect of fennel among menopausal women. Methods: The present double-blinded and placebo-controlled trial examined the fennel effect on Pittsburgh Sleep Quality Index (PSQI). Total score and relevant 7 components, including sleep duration, sleep latency, use of sleeping medication, subjective sleep quality, sleep disturbances, daytime dysfunction and habitual sleep efficiency among 50 menopausal women compared to control group within a 12-week follow-up. Results: The patients in both groups reported no certain side effects and all subjects completed the study. The mean actual sleep duration was 5 hours and 66 minutes. Intergroup comparison revealed no statistically significant differences in the mean total PSQI score (P = 0.439), subjective sleep quality (P = 0.826), habitual sleep efficiency (P = 0.127), sleep disturbances (P = 0.130), use of sleeping medication (P = 0.52) and daytime dysfunction (P = 0.439). A tendency toward significant between 2 groups was seen concerning the sleep duration (P = 0.059). Intergroup comparison showed significantly borderline levels (P = 0.059). Conclusions: The treatment of 12 weeks with fennel caused a slight effect that did not reach to significant. These findings should be considered cautiously because of small sample size, short-term follow-up and subjective measure of sleep quality.

Insomnia has become a major public health issue in recent times. Although quality of sleep is affected by environmental, psychophysiological, and pharmacological factors, diet and nutrient intake also contribute to sleep problems. This study investigated the association between nutrient intake and co-morbid symptoms associated with sleep status among selected adults. Subjects in this study included 87 men and women aged 21-45 years. Presence of insomnia was assessed using the Insomnia Screening Questionnaire, and dietary intake was measured over three consecutive days by dietary survey. Descriptive analysis, ANOVA, and Chi-Square tests were performed to compute and interpret the data. Approximately 60% of the participants were insomniacs. People with insomnia consumed significantly lesser quantities of nutrients as compared to normal sleepers. Differences in intakes of energy, carbohydrates, folic acid, and $B_{12}$ were highly significant (P < 0.002). Further, intakes of protein, fat, and thiamine were significantly different (P < 0.021) between insomniacs and normal sleepers. The nutrient intake pattern of the insomniacs with co-morbid symptoms was quite different from that of the normal sleepers. Based on these results, it is probable that there is an association between nutrition deficiency, co-morbid symptoms, and sleep status. More studies are required to confirm these results.

Objectives: The purpose of this overview was to summarize the evidence regarding the effectiveness of Cognitive Behavioral Therapy (CBT) for sleep disorders through systematic reviews (SRs) and meta-analyses (MAs). Methods: An overview of systematic review was conducted according to the study protocol (reviewregistry1320). A comprehensive literature search was performed using three databases (Pubmed, Cochrane Central Register of Controlled Trials, and Web of Science) and three Korean databases (KoreaMed, KMbase, and ScienceON). Final studies were selected by three authors according to inclusion and exclusion criteria, and data needed for analysis were extracted by a pre-planned extraction framework. Methodological quality of systematic review was assessed using the 'Assessment of multiple systematic reviews 2 (AMSTAR2)'. Results: Fourteen SRs and MAs were included, of which eleven SRs were performed MAs. Twelve studies studied insomnia among sleep disorders, and the rest are nightmares and sleep disturbances with PTSD. Ten studies reported the effect of CBT on sleep disorders measured by insomnia severity index (ISI) and sleep onset latency (SOL), and all reported a significant improvement effect. Eight studies reported the effect of CBT on sleep disorders measured by wake time after sleep onset (WASO), and seven studies reported a significant improvement effect. The methodological quality of the studies evaluated with AMSTAR 2 was mainly low or very low because of omission of protocol registration and excluded study list. Conclusions: Practical guidelines and studies show that CBT is effective for sleep disorders, but access to CBT needs to be improved.

This experiment was performed to investigate whether the combined-preparation of water extracts of germinated brown rice (WGR), water extracts of cultured mountain ginseng (WCG) and 70% ethanol extracts of Longanae Arillus (ELA) has hypnotic effects and/or enhances pentobarbital-induced sleep behaviors through the GABAergic system. The combined-preparation of WGR and WCG reduced sleep latency and prolonged sleep time induced by pentobarbital. ELA also reduced sleep latency and prolonged sleep time induced by pentobarbital. However, WGR or WCG itself did not induce sleep. The combined-preparation of WGR, WCG and ELA strongly reduced sleep latency and prolonged sleep time via chloride influx into primary cultured cerebellar granule cells. In conclusion, the combined-preparation of WGR, WCG and ELA augments pentobarbital-induced sleep behaviors through the modification of GABAergic system.
