The purpose of this study is to identify the objective picture of developmental pattern of marital satisfaction of couples based on family life cycle length of marriage marriage cohort birth cohort and age of couples using data from 317 couples in urban cities. The result indicate that the U-curve of marital satisfaction is the special pattern of family life cycle while W-curve is more dominant pattern when data are analysed with length of marriage birth cohort and marriage cohort. The couples differ in their assessment of marital satisfaction through entire their life span which seems for wives to become more dissatisfied over time. The similarity of developmental pattern the spouses appears only in their birth cohort. Discussion and recommendations for future research of the marital satisfaction are suggested.

Objective: The purpose of this study was to examine children's disclosure to parents in different domains of their daily activities. Methods: The participants were 340 children(100 kindergarteners, 120 3rd graders and 120 6th graders in elementary school) and their mothers in Seoul and Gangwon-do, Korea. The data was analyzed with one-way ANOVA, paired t-test, and MANOVA. Results: First, 3rd graders and 6th graders experienced more daily activities than kindergarteners in most domains. Second, 3rd graders disclosed more than kindergarteners and 6th graders in most domains. The response of mothers with 3rd graders was most similar to their children's response about children's disclosure to parents. Third, the reasons for nondisclosure of children were different according to domains. The reasons for nondisclosure of children that mothers perceived were different from those of their children, especially in the school(institute)-related domain. Conclusion/Implications: The results of this study indicated that the aspects of children's disclosure to parents were different according to domains of their daily activities based on developmental stages. Mothers perceived their children's disclosure differently compared to their children. The results suggest that it is necessary to approach children's disclosure to parents based on domains of daily activities and developmental stages.

This study sought to investigate and assess the development patterns of children, aged from 3 to 5, by means of a longitudinal approach. The children's developmental patterns are classified according to five curriculum areas; physical health, social skills, expression, language, and exploration-. The developmental patterns are analyzed in detail according to the observation period, children's ages, and their genders. The subjects consisted of 108 children in A city. A research assistant was asked to observe and keep records of the children's behaviors at three distinct times -early, middle, and late in the school year. The 'observational scale for children' was used as the measurement tool. The data which was thus collected was then subject to statistical analysis. The major findings of the study are as follows. First, there were significant differences in all five curriculum areas according to the children's age and observation period. That is, five-year-old children showed higher scores than three- and four-year-old children. Second, there were significant differences in the social development within five curriculum areas according to the children's gender and the observation period. That is, girls exhibited higher scores than boys.

This study focuses on the relationship between time management behavior and parenting stress of mothers with developmentally disabled children. The participants of this study were 162 mothers whose children have developmental disabilities and attend pre-school and social welfare centers for early education. This study investigates the time management behaviors of the participants, and whether these behaviors have an effect on their time management satisfaction and parenting stress. The findings were as follows: 1) The time management behaviors of the participants were lower than average, scoring 2.87 out of 5. The order of dimensional scores from highest to lowest were sequencing, planning, recording habits, evaluating, and setting goals. 2) Time management satisfaction and parenting stress for the participants exhibited a negative correlation. 3) Adaptation behaviors of the children and time management behaviors of the mothers were factors that had significant effects on the mothers' parenting stress. These results showed the importance of time management for mothers with developmentally disabled children.

Purpose: This study aimed to develop and evaluate the effectiveness of an educational program on developmental positioning (EPDP) for nurses in neonatal intensive care units (NICUs). Methods: The study utilized a non-equivalent control group pretest-posttest design. Sixty NICU nurses were recruited from two university hospitals in Daejeon, South Korea. The EPDP consisted of a 7-week program: 3 weeks of education and practice, followed by 4 weeks of encouragement messages using social networking services. Developmental positioning (DP) posters and DP aids were also provided during the intervention period. The intervention group (n=30) received the EPDP, but not the control group. The data were analyzed using the 𝜒² test, the Fisher exact test, the independent t-test, and repeated-measures analysis of variance. Results: Participants' knowledge (t=7.49, p<.001), attitudes (t=1.99, p=.001), self-efficacy (t=2.99, p=.004), performance of DP (t=2.98, p=.004) and Infant Positioning Assessment Tool (IPAT) scores (F=29.50, p<.001) were significantly higher in the intervention group than in the control group. Conclusion: The EPDP can be an effective and useful program for improving the performance of DP among NICU nurses by increasing their knowledge, attitudes, and self-efficacy of DP. However, further research involving various NICU settings is needed to gather more empirical evidence.

Purpose: This study aimed to develop and evaluate a mobile application focusing on developmental support care for infants born prematurely. Methods: An application was developed using the analysis, design, development, implementation, and evaluation model. In the analysis phase, previous research was evaluated through big data text-mining and a literature review. In the design phase, the preliminary content of the application was designed, and the content validity and comprehension were verified. A hybrid application was developed and used by eight experts and ten users, who evaluated the layout of the mobile application and their satisfaction with it. Results: The content of the designed application comprised a diary, customized information, developmental play, and community. The mean scores for layout were 3.73±0.47 and 3.43±0.68 out of 4 points among the experts and users, respectively. Users' mean satisfaction score was 3.70±0.70 out of 5 points. Conclusion: The information provided by the mobile application was evaluated as consistent and systematic. The application was also found to be satisfactory by infants' parents. The mobile application developed through this study is expected to be effective in supporting the development of children born prematurely.

This study aims to compare the word decoding skills, phonological awareness (PA), rapid automatized naming (RAN) skills, and letter knowledge of first graders with developmental dyslexia (DD) and those who were typically developing (TD). Eighteen children with DD and eighteen TD children, matched by nonverbal intelligence and discourse ability, participated in the study. Word decoding of Korean language-based reading assessment(Pae et al., 2015) was conducted. Phoneme-grapheme correspondent words were analyzed according to whether the word has meaning, whether the syllable has a final consonant, and the position of the grapheme in the syllable. Letter knowledge asked about the names and sounds of 12 consonants and 6 vowels. The children's PA of word, syllable, body-coda, and phoneme blending was tested. Object and letter RAN was measured in seconds. The decoding difficulty of non-words was more noticeable in the DD group than in the TD one. The TD children read the syllable initial and syllable final position with 99% correctness. Children with DD read with 80% and 82% correctness, respectively. In addition, the DD group had more difficulty in decoding words with two patchims when compared with the TD one. The DD group read only 57% of words with two patchims correctly, while the TD one read 91% correctly. There were significant differences in body-coda PA, phoneme level PA, letter RAN, object RAN, and letter-sound knowledge between the two groups. This study confirms the existence of Korean developmental dyslexics, and the urgent need for the inclusion of a Korean-specific phonics approach in the education system.
