The sleep is the most important problem for new parents. However, there were very rare the study about sleep of normal neonates and early infants in Korea. So we attempted pilot survey study of neonates' sleep pattern. The purpose of this study was to investigate the sleep pattern of normal neonates in Seoul and Kyungki area and to provide for basis for nursing intervention for parents of them. The subjects of this study were 37 normal full-term neonates of 2~3weeks of age who were visited by researcher or assistant at postpartum care unit, health care clinic, outpatient clinic located in Seoul and Kyungki area from April 20, 1999 to March 15, 2000. This study was descriptive survey study under the convenient sampling method. The instrument of this study was the NCASA translated by Korean Parent Child Health Academic Association. The collected data were coded as 1/4hour unit, and analyzed by MS Office Excel program. The result of this study were as followed: 1. The mean amount of total sleep was 15.1hours. The mean amount of daytime sleep was 9.5hours. The mean amount of nighttime sleep was 5.7 hours. The mean amount of longest sleep was 2.9hours. The mean amount of shortest sleep was 0.6hour. 2. The mean amount of total activity was 8.9hours. The mean amount of daytime activity was 6.5 hours. The mean amount of nighttime activity was 2.3hours. The frequency of feeding was 10.4 times a day. The frequency of daytime feeding was 7.3 times. The frequency of nighttime feeding was 3.1 times. It is suggested that various subjects and more data according to age, and comparative study among different cultures are needed for further study in the future.

Natural sleep pattern and its physiology in childhood are much different from those in adulthood. Several aspects of clinical evaluation for sleepiness in childhood are more difficult than in adulthood. These difficulties are due to several factors. First, excessive sleepiness in childhood do not always develop functional impairments. Second, objective test such as MSLT may not be reliable since it is hard to be certain that the child understand instructions. Third, sleepiness in children is often obscured by irritability. paradoxical hyperactivity, or behavioral disturbances. Anseguently, careful clinical evaluation is needed for the sleepy children. Usual causes of sleepiness in children are the disorders that induce insufficient sleep such as sleep apnea syndrome, schedule disorder, underlying medical and psychiatric disorder, and so forth. After excluding such factors, we can diagnose the hypersomnic disorders such as narcolepsy, Kleine-Levin syndrome, and idiopathic central nervous system hypersomnia. Among the variety of those causes of sleepiness, I reviewed the clinical difference of narcolepsy and obstructive sleep apnea syndrome in childhood compared with in adulthood. Recognition of the childhood narcolepsy is difficult because even severely sleepy children often do not develop pathognomic cataplexy and associated REM phenomena until much later. Since childhood narcolepsy give srise to many psychological, academical problem. Practicers should be concerned about these aspects. Childhood obstructive sleep apnea syndrome is different from adult obstructive sleep apnea syndrome too. Several aspects such as pathophysiology. clinical feature, diagnostic criteria, complication, management, and prognosis differ from those in the adult syndrome. An important feature of childhood obstructive sleep apnea syndrome is the variety of severe complications such as behavioral disorders, cognitive impairment, cardiovascular symptoms, developmental delay, and ever death. Fortunately, surgical interventions like adenotosillectomy or UPPP are more effective for Childhood OSA than adult form. CPAP is a "safe, effective, and well-tolerated" treatment modality too. So if early detection and proper management of childhood OSA were done, the severe complication would be prevented or ever cured.

The purpose of this study was to investigate the relations between sensory processing and sleep disturbances and to investigate the effect of sensory processing on sleep disorder in preschool children with developmental disorder. This study was conducted for 110 children with developmental disorder in developmental clinic and rehabilitation hospital in Gwang Ju from June to August, 2017. The final 109 data were analyzed. Sensory processing and Sleep disturbances were measured using the Shortened sensory profile(SSP) and Korean-the Children's Sleep Habits Questionnaire(K-CSHQ). Statistical analysis was performed using descriptive analysis, Pearson correlation analysis, and multiple regression analysis were performed. Children with developmental disorder had problems with sensory processing and sleep habits. Sensory processing was related to sleep habit and most important factors of sensory processing influencing sleep was taste/olfactory sensitivity, auditory filtering. Conclusion: In order to help children with developmental disorder with sleep problem, it is necessary to consider the sensory processing especially taste/olfactory sensitivity, auditory filtering.

Objectives: The purpose of this study was to develop a screening tool that is simple and easy to use for assessing sleep problems, including hypersomnolence, restless legs syndrome, and insomnia. We also examined the reliability and validity of this tool. Methods: We developed the Sleep Problem Screening Questionnaire (SPSQ), which consists of three sub-sections: insomnia (SPSQi), hypersomnolence (SPSQh), and restless legs syndrome (SPSQr). Subsequently, the participants, consisting of 222 patients with insomnia disorder and 78 healthy individuals, completed both the SPSQ and the comparative scale (Korean version of the Insomnia Severity Index). The analysis was then conducted using this data. Results: The SPSQ demonstrated good convergent and discriminant validity, as well as satisfactory internal consistency. A cutoff score of 6 on the SPSQi was found to be optimal for distinguishing individuals with insomnia. Conclusion: The results of this study suggest that the SPSQ is a reliable and valid tool for screening sleep problems among general adult population. However, there is a limitation as a comparison and validation with scales related to restless legs syndrome and hypersomnolence were not conducted.

Uvulopalatopharyngoplasty(UPPP) is an operation that is frequently performed for the patient of obstructive sleep apnea(OSA). A major problem has been to select those patients who will have a good response to UPPP. We compared preoperative and postoperative polysomnography(PSG) in 20 patients to evaluate the success rate of the operation. Each subject underwent a cephalometric roentgenogram, and fiberoptic nasopharyngoscopy with Mueller maneuver was applied in roentgenogram and fiberoptic nasopharyngoscopy with Mueller maneuver was applied in preop evaluation of patients with OSA. No PSG parameter could accurately predict the changes in sleep after UPPP. There were no significant differences between the responders and the nonresponders concerning the cephalometric analysis, the type of obstruction by Mueller maneuver, and body mass index(BMI). The conclusions of this study are thus that UPPP is an effective treatment for the OSAS with a high success rate, but that there is no single useful parameter predicting the success of the operation.

This study was performed in order to investigate the stress levels, sleep, anthropometric measurement and nutrient intakes their correlations of college students. General characteristics, stress scores using a stress test, sleep scores using a sleep test, anthropometric measurement, body composition using Inbody 3.0 and nutrient intakes using 3-day recalls were measured in 353 subjects (183 males and 170 females). Mean total stress score of the male students was 68.2${\pm}$45.0 and that of the female students was 86.5${\pm}$48.7. Stress for study, future, economic and value-related factors were higher than other factors in both male and female students. Female students were more stressed than male in friend, family, study, future and value-related factors. Mean sleeping time and sleep scores of the male students were 7.0 hrs and 40.6${\pm}$5.7, respectively and that of the female students were 7.1 hrs and 41.5${\pm}$5.3, respectively. Mean height, weight, percent body fat (PBF) and waist-hip ratio (WHR) of the male students were 174.8 cm, 73.3 kg, 19.0% and 0.84, respectively. Mean height, weight, PBF, and WHR of the female students were 161.7 cm, 55.3 kg, 28.7% and 0.81, respectively. Mean energy and protein intakes of the male students were 2026.3 kcal (77.9% EER) and 83.0 g (150.9% RI) and those of the female students were 1538.2 kcal (73.2% EER) and 60.7 g (134.9% RI), respectively. In male students, sleep duration, professor and future problem showed significantly negative correlation (p<0.05). For both male and female students, in correlations between sleep scores, life stress experience frequency and importance, the total scores showed significantly negative correlation (p<0.01). Sleep scores (sleep quality) have more significant correlation than sleep duration in life stress. In male students, correlations between economic problem and weight, waist circumference and hip circumference showed significantly negative correlation. In female students, correlations between different gender problem and body mass index (p<0.05), PBF (p<0.01), WHR (p<0.01) and obesity degree (p<0.05) showed significantly negative correlation while correlation between study problem and PBF (p<0.05), WHR (p<0.05) showed significantly positive correlation. In male students, there were significantly positive correlations between life stress experience frequency and carbohydrate calcium, iron, vitamin A; correlation between importance and calcium, iron as well as correlation between total life stress scores and iron (p<0.05). In female students, correlation between life stress experience frequency and thiamin along with correlation between importance and thiamin showed significant negative correlation (p<0.05). College students need to practice good life habits for the purpose of correctly managing life stress.

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.

Purpose: To find out the relationship between the shift work, and disrupted sleep and consequent fatigue symptoms. Methods: The questionnaires were given to 345 nurses of 4 hospitals with over 400 beds in Daejeon. Results: The shift workers showed worse subjective quality of sleep than the daytime workers, and had significantly higher frequency of "cannot get to sleep within 30 minutes", "wake up in the middle of the night" and "wake up in the early morning". The shift workers had significantly higher scores of subjective symptoms of fatigue than the daytime workers, and the fatigue was found to be the mental type. The subjective symptoms of fatigue scores were significantly higher in the group who had "cannot get to sleep within 30 minutes", "wake up in the middle of the night" and "wake up in the early morning". Conclusion: The study results indicated that the shift workers had the higher level of subjective symptoms of physical fatigue as well as the worse quality of sleep than the daytime workers. It is speculated that the factors attributable to the poor quality of sleep or sleep induction disorders of nurses of hospitals could be due in major part to adaptational difficulties resulting from frequent night shifts.

Over the past five years, the number of patients with sleep disorders has increased by about 250,000 from 840,000 in 2017 to 1.09 million in 2021. In addition, sleep disorder is a factor that causes dementia risk factors, and furthermore, the population with sleep disorder is a very important policy issue in terms of stable health insurance financial management in the future in terms of national health management in the super-aging trend. Therefore, this study aims to establish an efficient treatment environment in medical institutions responsible for the current status of polysomnography and effective reimbursement policies for the recently increasing population with sleep disorders, and appropriate sleep management policies for future sleep disorders through correct implementation. We are trying to find out the actual condition and improvement plan through interviews with related organizations and experts.

Korea worker is well known for its long work and amongst employees and to change un-healthy lifestyle. This study aims to investigate the association between health behaviors and sleep problems in employees. It employed data from the Third Korean Working Conditions Survey (KWCS). The total number of individuals included in the analysis was 34,788 employees, from the 2011 survey. The outcome was sleep problems, which had a prevalence rate of 2.5% in men and 2.3% in women. An adjusted odds ratios were as follows: 2.26(1.75-2.91) for hypertension, 2.21(1.60-3.06) for obesity, 26.82(21.51-33.45) for depression and 2.02(1.64-2.49) for high level of job stress. We need to invest to identify relevant and various health service promotion for sleep problem that un-healthy workers want will use.
