In this research, we designed representative motion patterns that possibly occurred in sleep situation and evaluated the feasibility of the smartphone based movement recording technique. For this, we designed 7 motions such as posture change, head movement, arm movement (vertical, horizontal), leg movement and hand movement (flipping, folding). Movement was recorded by using the smartphone and the actimetry device simultaneously for comparing the feasibility of smartphone based recording. As a result of experiment, we found that the smartphone based movement recording well reflects the body movement, however, it shows the limitation in recording the small local movement such as hand motion compared with the reference actimetry device, Actiwatch.

본 연구는 재가 노인들의 수면 양상을 확인하고 이와 관련된 우울과 인지기능의 관계에 대하여 확인하고 알아보기 위한 목적으로 실시하였다. 연구 방법은 2008년도 실시된 전국 노인 생활 실태 및 복지 요구 조사(보건복지부, 2008)의 원자료를 활용하였고, 대상자는 만 65세 이상의 남녀 12,087명이었으며 연구에 사용된 도구들은 연령, 성별, 나이, 기상 시 숙면 정도, 하루의 총 수면시간, 우울, 인지 기능의 자료를 활용하여 이차 자료분석(secondary data analysis)으로 설계하였다. 연구 결과 인구학적으로는 나이가 많은 여성들이 수면 양상이 좋지 않았으며 양적 수면의 형태인 하루의 총 수면 시간과 우울과 인지기능의 관계에서는 하루의 총 수면 시간이 6시간 이하이거나 9시간을 넘을 경우 우울 증상이 더 많았으며 질적 수면의 형태인 기상 시 숙면 정도와 우울과 인지기능의 관계에서는 숙면의 횟수가 적을수록 우울, 인지기능이 저하되었다. 이상의 결과에 근거하여 수면 양상의 변화가 노인들에게서 병적이라고 할 수는 없지만 위의 결과들을 볼 때 일차 보건 현장에서 노인들의 일상생활에서 수면의 역할을 이해하기 위해서 수면의 시간과 같은 수면의 양, 숙면 정도와 같은 수면의 질에도 초점을 두어 다각적인 접근을 통하여 노인들의 수면 양상을 확인하고 수면 장애를 관리하기 위하여 대상자 개개인에게 맞는 여러 방법의 중재 프로그램을 연구하고 개발하는 것이 필요하다고 하겠다.

Background: Law enforcement communications (i.e., 911 dispatch and call takers) is a challenging and stressful occupation. The purpose of this study is to identify the main stressors associated with employment in law enforcement communications, and to identify and provide context to how these stressors affect workers' health and wellbeing. Methods: This research study included focus groups with 23 call takers and 911 dispatchers employed by a large, urban law enforcement agency in 2018. Thematic analyses were conducted to identify trends. Results: Four themes of stressors emerged (i.e., the high stakes nature of some 911 calls for service, understaffing, supervisor-related stress, and recruiting practice). Two health-related themes emerged as being occupation-related: weight gain and poor sleep patterns/insufficient sleep). Specifically, participants reported negative eating habits resulting in weight gain and obesity, lack of sleep and irregular sleep schedules, and development of hypertension and/or diabetes since beginning their jobs. Conclusion: Law enforcement communications professionals experience a number of the same stressors facing law enforcement officers in patrol. These stressors, combined with the sedentary nature of the job, could result in long-term, chronic health problems.

Objective: Diminished ovarian reserve (DOR) is a disorder characterized by impaired ovarian function. Sleep disorders are disruptions of the circadian rhythm, which appears to be closely linked to reproductive systems. This study aimed to investigate the impact of poor sleep quality on the ovarian reserve of childbearing-age women. Methods: A cross-sectional study was conducted in China from June 2021 to March 2023. In total, 102 participants diagnosed with chronic insomnia disorder were included in the study. Questionnaires were administered to assess participants' menstrual patterns, insomnia severity, anxiety, and depression. The anti-Müllerian hormone level and the basal antral follicle count were measured for ovarian reserve evaluation. Correlation analysis and ordinal logistic regression analysis were conducted. Results: The women with insomnia presented high percentages of hypomenorrhea, premenstrual syndrome, and dysmenorrhea (78.4%, 74.5%, and 46.1%, respectively). Severe sleep disorder in the past month was identified as an independent risk factor for hypomenorrhea and premenstrual syndrome (odds ratio [OR], 2.64 and OR, 2.688; p<0.05). The prevalence of DOR among women with insomnia (33.3%) was significantly higher than the average reported in previous studies for young women. Insomnia duration exceeding 1 year was determined to be an independent risk factor for DOR in women aged 36 to 40 years (OR, 4.5; p=0.033). Conclusion: This study highlights the association between sleep disorders and menstrual problems. Prolonged poor sleep quality in women aged 36 to 40 years was identified as a significant risk factor for DOR. We should pay more attention to improving sleep quality in order to maintain normal ovarian function.

The purpose of this study was to recognized the sleep activity patterns of the normal infants in Korea. The subject were 41 normal infants who were below 8 weeks old and were born in Taegu city and Kyungbuk province. The measuring instrument the sleep activity was NCASA translated by the Korean-parent-child Health Academic Association. The data that were collected from April, 18 1999 to January 1, 2000 were analysed by the SPSS 7.5 program. The results of the study was summarized as follow; 1) The mean amount of total sleeping hours per day was decreased from $16.27{\pm}1.96$ hr at the 1st week, to $15.19{\pm}2.39$ hr at the 2nd week, to $13.66{\pm}2.40$ hr at the 3 week but increased to $16.55{\pm}5.77$ hr at the 4-8 week after birth. 2) The mean frequency of feeding was increased to $9.43{\pm}2.79$ times at the 3rd week but decreased to $7.55{\pm}1.23$ times at the 4-8th week after birth. 3) The regularity of day time sleep was decreased from 50.00% to 19.79% and that of night time sleep was increased from 51.79% to 72.92%. 4) The regularity of feeding was increased from 30.42% at the 1st week to 50.07% at the 2nd week but decreased 26.34% at the 4-8th week after birth. 5) The longest period of day time sleep was decreased to $2.39{\pm}0.42$ hr at the 3rd week but increased $2.47{\pm}0.69$ hr at the 4-8th week after birth. The longest period of night time sleep was decreased to $2.58{\pm}0.67$ hr at the 2nd week but increased to $3.00{\pm}1.32$ at the 3rd week and $4.30{\pm}1.16$ hr at the 4-8th week after birth. 6) At the 1st week, the 2nd week, the 3rd week after birth, the frequency of day time feeding was positively correlated with the frequency of night time feeding($R_{1week}=0.948^{**}$, $R_{2week}=0.927^{**}$, $R_{3week}=0.779^{**})$. At the 4-8th week after birth, the frequency of night time feeding was negatively correlated with the amount of night time sleep ($R_{4week-8week}=0.875^{*}$). On the basis of above findings, the following is suggested; It is need a longitudinal and transcultural study which are designed for children's sleep and feeding.
