Objectives: Professional firefighters face various health hazards and are required to maintain both physical and mental fitness to effectively mitigate crises and respond to emergencies. Moreover, the long working hours and shift work of this profession impact sleep quality. This study investigated the quality of sleep and its associated factors among firefighters in Bangkok, Thailand. Methods: This was a cross-sectional study of firefighters affiliated with the Bangkok Fire and Rescue Department, Bangkok Metropolitan Administration, Thailand between January 2023 and March 2023. A cluster random sampling technique was utilized to distribute 600 questionnaires to firefighters in 15 fire stations. The questionnaire addressed demographic, work-related, and environmental factors. Sleep quality was assessed using the Thai version of the Pittsburgh Sleep Quality Index (PSQI). Data analysis involved both descriptive and inferential statistics. Bivariate and multiple logistic regressions were performed. Results: The response rate was 78.7% (n=472), and 44.1% of the firefighters reported poor sleep quality (PSQI score >5). Sleep quality was statistically associated with conflicting family relationships (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.1 to 2.9), additional part-time jobs (daytime, OR, 2.4; 95% CI, 1.3 to 4.4; or nighttime, OR, 4.3; 95% CI, 1.1 to 16.7), noisy sleeping areas (OR, 1.7; 95% CI, 1.1 to 2.8), and the availability of adequate bedding (OR, 3.0; 95% CI, 1.8 to 4.9). Conclusions: Poor sleep quality among firefighters was associated with various personal, work-related, and environmental factors. Organizations should promote policies that improve sleep quality through good sleep hygiene practices and facilities.

Purpose: This study aimed to investigate problem behavior and its related factors in school-aged children. Methods: A descriptive correlational study was conducted with 221 mothers of children at 1st to 6th grades. Data were collected from March to April, 2015 using self-report structured questionnaires. Questionnaires included characteristics of subjects, Korean Child Behavior Checklist for measuring problem behavior and Children's Sleep Habits Questionnaire for assessing sleeping habits. Collected data were analyzed by independent t-test, $x^2$ test, and multiple logistic regression. Results: In logistic regression analysis, having any maternal job (aOR=2.8, 95% CI=1.1~6.9) and higher daytime sleepiness (aOR=2.9, 95% CI=1.2~7.4) were statistically significant contributors of internal problems. Higher bedtime resistance (aOR=2.2, 95% CI=1.0~4.9) and higher daytime sleepiness (aOR=2.8, 95% CI=1.2~6.3) were statistically significant contributors of external problems. Higher bedtime resistance (aOR=4.3, 95% CI=1.5~12.4) was statistically significant contributors of total problem behavior. Conclusion: School-aged children with sleeping problem are at risk for problem behavior. More attention is need to consider sleeping habits for supporting behavioral improvement in school-aged children.

Electrophysiological recordings are considered a reliable method of assessing a person's alertness. Sleep medicine is asked to offer objective methods to measure daytime alertness, tiredness and sleepiness. As EEG signals are non-stationary, the conventional method of frequency analysis is not highly successful in recognition of alertness level. In this paper, EEG signals have been analyzed using wavelet transform as well as discrete wavelet transform and classification using statistical classifiers such as euclidean and mahalanobis distance classifiers and a promising method SVM (Support Vector Machine). As a result of simulation, the average values of accuracies for the Linear Discriminant Analysis (LDA)-Quadratic, k-Nearest Neighbors (k-NN)-Euclidean, and Linear SVM were 48%, 34.2%, and 86%, respectively. The experimental results show that SVM classification method offer the better performance for reliable classification of the EEG signal in comparison with the other classification methods.

A growing number of people are concerned about their sleep. There are many people with chronic sleep disorders. As there are various causes in a disease, proper treatment according to each cause is necessary for a more effective treatment. In general, insomnia is classified into five categories of physical, physiological, psychological, psychiatric and pharmacological aspects. Sedative-hypnotics including benzodiazepine and non-benzodiazepine have widely been used in chronic insomniacs. However, most hypnotics including non-benzodiazepine cause some of dependence, tolerance, impaired daytime function and rebound insomnia. Therefore, we are looking forward to proposing an effective oriental treatment for insomnia. A 71-year-old male who had suffered from cerebral infarction was admitted to our department for oriental treatment of stroke and insomnia. Initial treatment modalities with administration of paroxetine were not effective. However administration of oriental medicine' Gochimmuwoo-san(Gaozhenwuyou-san)' achieved a desirable effect.

Insomnia is a disorder of initiaton and maintenance of sleep that results in daytime sleepiness and dysfunction, and arises from multiple psychological, physiologic and environmental factors. A number of stroke patients suffer from insomnia classified as one of the sleep disorders associated with physical illness and on the contrary insomnia may have profound deleterious effects on the natural course of stroke. We experiened three cases of stroke patients with insomnia. In the point of Differentiation of Syndromes, these subjects were diagnosed as Excessive heat-fire syndrome of stroke and were administrated with Hwangyeonhaedog-tang Gamibang. After treatment, both sleep patterns and other accompanied symptoms improved.

Childhood narcolepsy is one of the underdiagnosed diseases even the first symptoms often appear in childhood. Making diagnosis through history taking is not always easy because the symptoms of childhood narcolepsy are different from those of adulthood. Diagnostic laboratory tests such as sleep studies, tests for human leukocyte antigens, cerebrospinal fluid hypocretin measurement should be considered when the child has excessive daytime sleepiness without cataplexy. Treatment approach should be start as early as possible to avoid secondary academic, emotional difficulties. Both pharmacological and non-pharmacological management, and close cooperation between parents and school teachers should be maintained. In the near future, childhood narcolepsy can be a key to understand the pathogenesis of narcolepsy.

The prevalence of pediatric obstructive sleep apnea syndrome (OSAS) is approximately 3% in children. Adenotonsillar hypertrophy is the most common cause of OSAS in children, and obesity, hypotonic neuromuscular diseases, and craniofacial anomalies are other major risk factors. Snoring is the most common presenting complaint in children with OSAS, but the clinical presentation varies according to age. Agitated sleep with frequent postural changes, excessive sweating, or abnormal sleep positions such as hyperextension of neck or abnormal prone position may suggest a sleep-disordered breathing. Night terror, sleepwalking, and enuresis are frequently associated, during slow-wave sleep, with sleep-disordered breathing. Excessive daytime sleepiness becomes apparent in older children, whereas hyperactivity or inattention is usually predominant in younger children. Morning headache and poor appetite may also be present. As the cortical arousal threshold is higher in children, arousals are not easily developed and their sleep architectures are usually more conserved than those of adults. Untreated OSAS in children may result in various problems such as cognitive deficits, attention deficit/hyperactivity disorder, poor academic achievement, and emotional instability. Mild pulmonary hypertension is not uncommon. Rarely, cardiovascular complications such as cor pulmonale, heart failure, and systemic hypertension may develop in untreated cases. Failure to thrive and delayed development are serious problems in younger children with OSAS. Diagnosis of pediatric OSAS should be based on snoring, relevant history of sleep disruption, findings of any narrow or collapsible portions of upper airway, and confirmed by polysomnography. Early diagnosis of pediatric OSAS is critical to prevent complications with appropriate interventions.

The purpose of this study was to examine the anatomic changes in the upper airway with a dental orthosis. the effectiveness and side effects of orthosis in the treatment of snoring and obstructive sleep apnea. To meet this puppose a dental orthosis, designed to increase the size of the upper airway by advancing the mandible, was used in 42 patients (30 M, 12 F), aged 29 - 69 years, to treat snoring and varying decrees of obstructive sleep apnea. Cephalometric study of anatomic featured was made with and without a dental orthosis, and the evaluation of the effectiveness and side effects of orthosis was done by questionnaires. The obtained results were as follows : 1. All subjects were habitual snorers and 32 patients comp1ained the loudness of snoring as severe as be heard outside of the patient's room. 2. According to the degree of respiratory distirbance index(RDI) and aprea index(Al) from the polysomnograph in 34 patient, mild obstructive sleep apnea patients were 5, moderate 6 and severe 16. 3. Various anatomic changes in the upper airway with denta1 orthosis were as follows : (1) More superioly positioned hyoid bone ( p<0.001) (2) Enlarged oropharyngeal (superior p<0.01, middle p<0.01. inferior p<0.01) and hypopharyngeal (P<0.05) airway space. 4. According to the results of the changes of clinical syptoms after the usage of the dental orthosis acquired from questionnaires, there was significant improvement in the frequently, the loudness and the severity of snoring, cessation of breathing and awakening from the difficulty of breathing during sleep. 5. The effectiveness and side effects of dental orthosis by questionnaires were as follows ; (1) Dental orthosis satisfied almost all the patients (68±20%). (2) Snoring was improved in all the patients (73±19%). (3) Obstructive sleep aphea was improved in all the patients (61 ± 37%) (4) Sleepiness in the daytime was significantly improved (61 ±37%). (5) The sleep quality was significantly improved (61±37%). (6) The discomfort of the dental orthosis was minor (33±18%) and no serious complications were observed. 6. The dental orthosis is an effective treatment for the symptom of snoring, and it can also effectively treat varying degrees of obstructive sleep apnea.

Purpose: The purpose of this study was to investigate the relationships between LLFDI and quality of sleep in older men with prostatic hypertrophic symptoms. Methods: The secondary analysis of data collected for the 2nd stage BK(Brain Korea)21 project was performed. The original data were collected using a cross-sectional, face-to-face, and private interview method. The questionnaires consisted of prostatic hypertrophic symptoms, late-life function and disability, quality of sleep, and demographic profiles. Results: A total of 112 older men included in this study. The major findings of this study were as follow; 1) 29.5% of participants had more than moderate symptoms of prostatic hypertrophy. 2) There were a significant positive correlation of prostatic hypertrophic symptoms with subjective sleep quality, sleep latency, sleep disturbances, use of sleeping medication, and daytime dysfunction found, whereas there was a negative relationship with frequency dimension. 3) The LLFDI is significantly associated with urgency, weak stream, and intermittency. The quality of sleep is significantly associated with weak stream which explained 11.2% of variance. Conclusion: These results may contribute to a better understanding late-life function and disability, quality of sleep in older men with prostatic hypertrophic symptoms. Therefore, health programs for prompting older men's health should be planned based on results of the study.
