Purpose: The purposes of this study were to investigate hospital nurses' job stress, sleep disturbance, and fatigue and to examine the relationships among them. Methods: The subjects were 119 registered nurses working in two hospitals. The data were collected from September 1 to September 30, 2015 using self-report questionnaires. The data were analyzed using SPSS 20.0 program. Results: Job stress levels of nurses were middle or higher level. Nurses levels of sleep disorders was higher than the median. It was the middle of the fatigue level of the nurses. There was a difference between sleep disorders and fatigue, depending on age and working department. There was a significant quantitative correlation among stress, sleep disorders, and fatigue. Conclusion: Therefore, it is necessary to develop programs to reduce job stress and sleep disorders and fatigue of hospital nurses. And it requires institutional improvements.

유아교사의 놀이신념과 유아 놀이성의 관계에서 유아교사의 수업환경조절전략 활용능력 매개효과
하혜진(Hye Jin Ha),손원경(Won Kyoung Son) 학습자중심교과교육학회 2024 학습자중심교과교육연구 Vol.24 No.17
목적 본 연구의 목적은 유아교사의 놀이신념과 유아 놀이성의 관계에서 유아교사의 수업환경조절전략 활용능력의 매개효과가 어떠한지 알아보는데 있다. 방법 이를 위하여 부산과 경남, 경북 지역의 유아교육기관에 근무하는 유아반 담임교사 163명을 대상으로 설문조사를 실시하였다. 수집된 자료는 SPSS 24.0프로그램을 사용하여 분석하고 매개효과를 검증하기 위하여 Baron과 Kenny(1986)의 3단계 회귀분석을 실시하였다. 결과 연구결과는 첫째, 유아교사의 놀이신념과 수업환경조절전략 활용능력, 유아의 놀이성 간에 유의미한 정적 상관관계가 있는 것으로 나타났다. 둘째, 유아교사의 수업환경조절전략 활용능력은 유아교사의 놀이신념과 유아의 놀이성 간의 관계에서 부분 매개효과가 있는 것으로 나타났다. 결론 본 연구는 유아교사의 놀이신념이 수업환경조절전략 활용능력을 부분 매개로 유아의 놀이성에 영향을 미치므로 유아교사가 긍정적인 놀이신념을 가지고 수업환경조절전략 활용능력을 증진시키는 것이 필요하다고 할 수 있다. 즉, 향후 유아의 놀이성 증진을 위한 교사역량 프로그램 개발에 유아교사의 놀이신념과 수업환경조절전략 활용능력이 포함되어야 함을 시사한다. Objectives The purpose of this study was to investigate the mediating effect of early childhood teachers' ability to utilize classroom environment regulating strategies on the relationship between their play beliefs and young children's playfulness. Methods A survey was conducted with 163 early childhood teachers working in preschools in the Busan, Gyeongnam, and Gyeongbuk regions of South Korea. The collected data were analyzed using SPSS 24.0, and to verify the mediating effect, a three-step regression analysis was conducted following Baron and Kenny's (1986) method. Results The results revealed significant positive correlations among early childhood teachers' play beliefs, their ability to utilize classroom environment regulating strategies, and young children's playfulness. Additionally, the ability to utilize classroom environment regulating strategies was found to partially mediate the relationship between early childhood teachers' play beliefs and young children's playfulness. Conclusions This study suggests that early childhood teachers' play beliefs indirectly influence young children's playfulness through their ability to utilize classroom environment regulating strategies. Therefore, it is necessary for early childhood teachers to develop positive play beliefs and enhance their ability to utilize classroom environment regulating strategies. Furthermore, the findings imply that future teacher training programs aimed at promoting young children's playfulness should incorporate both play beliefs and the ability to utilize classroom environment regulating strategies.

본 연구에서는 고등학교 학생들의 변위전류에 대한 궁금증에서 출발하여 직류전압이 걸린 평행판 축전기에서 자기장과 축전기에 삽입한 토로이드 코일에 유도되는 유도전압에 관한 몇 가지 공식을 얻었다. 이 공식을 바탕으로 통상적인 실험조건에 맞는 컴퓨터 계산 결과, 자기장은 MBL 장치의 자기장센서로는 측정이 불가능한 매우 작은 값으로 나왔으나, 유도전압은 저항 R값에 크게 의존하지만 전압센서로 측정이 가능한 범위의 값으로 나타났다. 따라서 직류전원을 사용하여 평행판 축전기에서 변위전류를 확인하기 위해서는 적당한 토로이드 코일을 축전기에 삽입하여 이것에 유도되는 유도전압을 측정하는 방법이 유용하다. 덧붙여서, 직류전압을 평행판축전기에 인가하여 변위전류를 확인하고자 하는 실험에서는 저항 R값의 선택이 매우 중요한 실험변수가 된다. In this study, we derived several formulas for magnetic fields and induced voltages in a parallel plate capacitor biased by DC voltages. The computer simulation based on the derived formulas reveals that the magnetic fields due to the displacement current fall within the range of 10<sup>- 10</sup>T to 10<sup>- 9</sup>T and thence the experiment for the displacement current is not possible because the magnetic field sensor used in Data Logger could measure the magnetic fields of above 10<sup>- 5</sup>T range. Contrary to this, the computer simulation confirms that the induced voltages in a toroidal coil due to the displacement current range measurable values of 0.002∼0.021V. The results imply that the displacement current can be confirmed by measuring the induced voltages in a toroidal coil inserted into a parallel plate capacitor under DC biasing.

The purpose of this study was to reveal association between oral health promotion behavior on psychological happiness and stress. Oral health promotion behavior was composed of dietary habits, toothbrushing, oral hygiene devices and regular dental visit. We thought these factors affect to the psychological happiness and stress. For this study, 200 adults in Busan, Ulsan and Kyungnam are participated in this study. The data were analyzed with descriptive statistics, t-test, ANOVA, pearson’s correlation coefficients, and stepwise multiple regression analysis with SPSS 21.0 program. In conclusion, we obtained the next results. First, the mean of oral health promotion behavior was 3.12 out of 5. In terms of sub-domain, toothbrushing (3.45) is the highest, followed by oral hygiene devices (3.09), dietary habits (2.75) and regular dental visit (2.66). Second, the influencing factor in stress were toothbrushing (β=-.169), adjusted R2=.024. Third, the influencing factor in psychological happiness were oral hygiene devices (β=.195) and dietary habits (β=.162), adjusted R2=.077. According to the results, toothbrushing is effective in decreasing the stress. Also, oral hygiene devices and dietary habits is effective in increasing the psychological happiness.
