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.

Objectives : Much is still unknown about the neurophysiological mechanisms or dynamics of the sleep onset process. Detrended fluctuation analysis (DFA) is a new tool for the analysis of electroencephalography (EEG) that may give us additional information about electrophysiological changes. The purpose of this study is to analyze long-range correlations of electroencephalographic signals by DFA and their changes in the sleep onset process. Methods : Thirty channel EEG was recorded in 61 healthy subjects (male:female=34:27, age=$27.2{\pm}3.0$ years). The scaling exponents, alpha, were calculated by DFA and compared between four kinds of 30s sleep-wakefulness states such as wakefulness, transition period, early sleep, and late sleep (stage 1). These four states were selected by the distribution of alpha and theta waves in O1 and O2 electrodes. Results : The scaling exponents, alpha, were significantly different in the four states during sleep onset periods, and also varied with the thirty leads. The interaction between the sleep states and the leads was significant. The means (${\pm}$ standard deviation) of alphas for the states were 0.94 (${\pm}0.12$), 0.98 (${\pm}0.12$), 1.10 (${\pm}0.10$), 1.07 (${\pm}0.07$) in the wakefulness, transitional period, early sleep and late sleep state respectively. The mean alpha of anterior fifteen leads was greater than that of posterior fifteen leads, and the two regions showed the different pattern of changes of the alpha during the sleep onset periods. Conclusions : The characteristic findings in the sleep onset period were the increasing pattern of scaling exponent of DFA, and the pattern was slightly but significantly different between fronto-temporal and parieto-occipital regions. It suggests that the long-range correlations of EEG have a tendency of increasing from wakefulness to early sleep, but anterior and posterior brain regions have different dynamical process. DFA, one of the nonlinear analytical methods for time series, may be a useful tool for the investigation of the sleep onset period.

The purpose of this study was to identify the sleep/activity patterns of neonates and to provide a baseline data for the development effective mother-infant relationship. Subjects of this study were 36 newborns aged 1-21 days and stayed in Postpartum Care Center in Taejon during the period of October 28th, 1999 to February 10th, 2000. The data were collected using NCASA developed by Barnard et al. and were analyzed with SPSS 7.5 for window program. The results of this study were as follows: 1. An average day sleep of neonates was 8.0 hours, night sleep was 3.6 hours, and total sleep was 11.6 hours. A longest period of day sleep was 3.8 hours and a longest period of night sleep was 3.4 hours. The regularity of day sleep was 22.1%, night sleep was 23.3%, and total was 22.1%. 2. The frequency of daytime feeding was 6.9, nighttime fee ding was 3.4, resulting in total of 10.3. The regularity of feeding was 37.4%, and the frequency of night awakening was 2.4. 3. Associations among variables related to neonate's sleep/activity records were as follows : - The regularity of total sleep was positively correlated with the frequencies of day sleep(r=.57, P=.00), night sleep (r=.40, P=.01), and total sleep(r=.65, P=.00). - The frequency of total feeding was negatively correlated with the frequencies of day sleep(r=-.29, P=.04), night sleep(r=-.39, P=.02), and total sleep(r=-.42, P=.00), as well as longest day sleep(r=-.50, P=.00). - The regularity of feeding was negatively correlated with the frequency of night sleep(r=-.35, P=.02), longest period of day sleep(r=-.32, P=.04), and longest period of night sleep(r=-.30. P=.04), whereas positively correlated with frequencies of daytime feeding (r=.29, P=.02) and nighttime feeding (r=.32, P=.05). - The frequency of night awakening was negatively correlated with amount of night sleep(r=-.39, P=.02) and frequency of daytime feeding(r=-.42, P=.01) while positively correlated with frequencies of nighttime feeding(r=.68, P=.00) and total feeding(r=.50, P=.00). 4. Although there was no statistical significant difference between sleep pattern and infant's age, following tendency was noted: - As baby gets older, total amount of sleep and longest period of day sleep decreased while longest period of night sleep increased. - As baby gets older, the regularity of day sleep decreased while the regularity of night sleep and total sleep slightly increased. - The frequencies of daytime and total feedings increased while the frequency of nighttime feeding decreased. In conclusion, the author found that the neonates of this study showed less amount of sleep, more night awakening, and more night time feedings than NCAST sample. There was a certain sleep/activity pattern existed: If babies were fed more frequently, daytime or nighttime sleeping hours became shorter, and if babies had longer daytime sleep, frequent nighttime awakenings were noted. This pattern illustrated the significant influence of feeding and sleep periods on each other. Awakening in the night is natural and normal patterns in the newborn period. The result of this study will provide information to parents about what to expect their infants.

Objectives The aim of this study was to examine the association between the sleep pattern, chronotype (midpoint of sleep on free days) and the depressive symptoms in adults aged 19 years and over in Korea. This study also investigated the mediating effect of perceived usual stress (PUS) and self-rated health (SRH) on the association between chronotype and depressive symptoms. Methods Among the subjects of the 7th Korea National Health and Nutrition Examination Survey (KNHANES) 2016 and 2018, 16142 adults aged 19 or over responded to the survey and finally 8604 were analyzed according to the exclusion conditions. Logistic regression analysis was conducted to see the risk of depressive symptoms, suicidal ideation over sleep pattern, chronotype. Finally, mediation analysis was performed in order to clarify how PUS and SRH are associated to chronoytpe and depression. Results After controlling for potential covariates, weekly sleep duration < 5 hours, ≥ 10 hours was associated with depressive symptoms. And late bed time sleeping after am 1:00 and later midpoints of sleep was associated with a higher level of depressive symptoms. Additionally, the PUS and SRH between chronotype and depressive symptoms showed a serial multiple mediation effect. Conclusions Short or long sleep duration, late bed time and later midpoints of sleep on free days are associated with depressive symptoms. Furthermore, the mechanism between chronotype and depressive symptoms needs to be further clarified by identifying the serial multiple mediation effects of PUS and SRH.

The cyclic alternating pattern (CAP) is a periodic EEG activity in NREM sleep, characterized by sequences of transient electrocortical events that are distinct from background EEG activities. A CAP cycle consists of two periodic EEG features, phase A and subsequent phase B whose durations are 2-60 s. At least two consecutive CAP cycles are required to define a CAP sequence. The CAP phase A is a phasic EEG event, such as delta bursts, vertex sharp transients, K-complex sequences, polyphasic bursts, K-alpha, intermittent alpha, and arousals. Phase B is repetitive periods of background EEG activity. The absence of CAP more than 60 seconds or an isolated phase A is classified as non-CAP. Phase A activities can be classified into three subtypes (A1, A2, and A3), based on the amounts of high-voltage slow waves (EEG synchrony) and low-amplitude fast rhythms (EEG desynchrony). CAP rate, the percentage of CAP durations in NREM sleep is considered to be a physiologic marker of the NREM sleep instability. In insomnia, the frequent discrepancy between self-reports and polysomnographic findings could be attributed to subtle abnormalities in the sleep tracing, which are overlooked by the conventional scoring methods. The conventional scoring scheme has superiority in analysis of macrostructure of sleep but shows limited power in finding arousals and transient EEG events that are major component of microstructure of sleep. But, it has recently been found that a significant correlation exists between CAP rate and the subjective estimates of the sleep quality in insomniacs and sleep-improving treatments often reduce the amount of CAP. Thus, the extension of conventional sleep measures with the new CAP variables, which appear to be the more sensitive to sleep disturbance, may improve our knowledge on the diagnosis and management of insomnia.
