Purpose: The quasi-experimental study was conducted to investigate the effects of the integrated NICU hospitalization education on maternal attachment, maternal self-esteem, and EPDS in the 26 mothers of high-risk infants(HRI). Method: The subjects were divided into the experimental group to received the integrated NICU hospitalization education included the enforced direct education of NICU and HRI to the mothers using a booklet and the provision of the neomaternal exposure as soon as possible after delivery. The control group received the routine education of the NICU hospitalization, mostly including the admission process and the NICU rules delivering to the husband. The research variables were maternal attachment, maternal self-esteem, and EPDS. Result: The results showed the increases in these variables after the integrated education in experimental group compared to the control group. Conclusion: It supports the benefits of the early direct NICU education and the neomaternal exposures on maternal adaptation process in the mothers of HRI.

Purpose: This study aimed to explore the subjective sleep quality of depressed and non-depressed mothers in the late postpartum period and to determine the relationship with their health promoting behaviors, family functioning, parenting stress. Method: A non-probability sample of 128 mothers completed a self-administered questionnaires at 4-6weeks postpartum. The Edinburgh postnatal Depression Scale (EPDS) and Pittsburgh Sleep Quality Index were used to measure mother's experiences of depression symptoms and sleep. Related factors of sleep quality were measured by the Korean Family Functioning Scale, Health Promoting Lifestyle Profile, and Parenting Stress Index. The data was analysed using t-test, one-way ANOVA, and the Pearson's correlation coefficients. Result: The results indicated that the depressed mothers (EPDS$\geq$ 10) had poorer sleep quality than the non-depressed mothers(EPDS < 10), reported shortened sleep duration, and experienced more daytime dysfunctions. Depressed mothers who had no job, did not drink coffee, and were primipara tended to report poorer sleep quality. There were significant correlation between poorer sleep quality and lower health promoting behaviors, higher family intimacy and lower family communication, and higher parenting stress among depressed mothers. Conclusion: Our findings support the view that depressed mothers' experiences of poor sleep are much higher than non-depressed mothers and multi-faced. Nurse professionals should screen for sleep problems in the depressed mothers with a different biopsychosocial and behavioral aspect from the non-depressed mothers in the late postpartum period.

Purpose: The purposes of this study were in understanding maternal and neonatal risk factors for postpartum depression using Edinburgh Postnatal Depression Scale(EPDS). Methods: Among 788 women, who had delivery include cesarean section in the department of obstetrics and gynecology at OO medical center from May 28th 2008 to October 6st 2009, 72 women filled out EPDS questionnaire sheets. Additional aspects included for the analysis are maternal factors including age, number of children, parity, delivery method, and hemoglobin; and neonatal factors such as weight, sex, gestational age, apgar score, and neonatal intensive care unit admission. Comparison was performed between the women with EPDS score equal or less than 8 and the women with EPDS score equal to or higher than 9 using statistical methods of student t-test for linear variables and chi-square test for non-linear variables. SPSS version 13.0 for windows was used for analysis. Results: Thirty women(41.7%) were included in the postpartum depression risk group (EPDS score ${\geqq}9$). Statistically significant difference(P<0.05) was found in gestational ages of the risk group($36.57{\pm}29.6$ weeks) and the non-risk group ($38.10{\pm}1.97$ weeks). Identified statistically significant risk factors(P<0.05) include cesarean section (OR=3.304 [1.121-9.744]), low birth weight infant(OR =6.500 [1.606-26.314]), preterm delivery(OR=2.857[1.071-7.621]), low apgar score (1minute) after delivery (OR=14.909 [1.750-127.025]). There was no statistically significant difference in maternal age, number of children, parity, hemoglobin, neonatal sex, apgar score (5minutes), NICU admission. Conclusions: Through the results showed, gestational age, delivery method, neonatal weight, apgar score(1minute) were identified as risk factors for postpartum depression. To prevent or minimize postpartum depression, oriental medical intervention is recommended for pregnant women through early detection.

The dielectric medium used in electrophoretic displays (EPDs) is required to be an environmentally friendly solvent with high density, low viscosity, and a large electric constant. Hydrofluoroether, a highly fluorinated solvent with eco-friendly characteristics, is regarded as a viable alternative medium for EPDs, owing to the similarity of its physical properties to those of the conventional EPD medium. Surface modification of particles is required, however, in order for it to disperse in the charged solvent. Also, positive/negative charges should be present on the particle surface to enable electrophoretic behavior. In this study, carbon black particles wrapped with positively charged nitrogen (N-CBs) were fabricated by a simple hydrothermal process using a poly(diallyldimethylammonium chloride) solution as a black coloring agent for the EPD. The dispersion behavior of N-CBs was investigated in various solvents.

We have developed the world's thinnest flexible electrophoretic displays (EPDs). The thin-film displays are 95 ..m thick, which is nearly the same thickness as a standard sheet of paper. Weighing 0.44g including external connection cables, these displays are also probably the world's lightest. We have also developed 7.1-inch-diagonal(paperback-sized) high-resolution flexible EPDs. The displays are large enough to be used as practical e-paper. More than 7 million transistors work correctly on plastic, enabling us to see 3-megapixel images. These flexible displays include active-matrix TFT devices that are fabricated using Suftla transfer technology. Suftla technology demonstrates the potential to achieve thin, flexible displays that will be used as an e-paper in the near future.

영상 압축은 멀티미디어 전송에 있어 핵심적인 기술이다. 동영상 압축 기술 중 움직임 예측은 H.264, MPEG-4 등의 압축 표준에서 시간적 중복성을 줄이기 위해 이용되고 있다. 따라서 영상의 압축 효율을 높이는 다양한 움직임 예측 알고리듬이 제안되었다. 이에 본 논문은 계산량을 줄이기 위해서 EPDS(Edge-Based Partial Distortion Search)를 기반으로 한 개선된 이단 탐색 움직임 예측 알고리듬을 제안한다. 이를 위하여 이단 탐색에서의 적응적 탐색 구간 적용 기술을 사용하였다. 제안한 알고리듬은 FS보다 98.11배 빠르다. 뿐만 아니라, PSNR을 통해 화질이 비슷하게 유지됨을 알 수 있다. 따라서 제안한 알고리듬은 고화질 디지털 영상 실시간 구현에 적합하다.
