Purpose: The purpose of this study was to examine the effect of a maternal self-efficacy promotion program for Korean primiparas on maternal confidence and mother-infant interaction. Method: This study was non-equivalent quasi-experimental research with a control group selected by purposive sampling. Based on Bandura’s (1986) self-efficacy theory, the research team developed the maternal self-efficacy promotion program. The program included achievement experiences, verbal persuasion, and vicarious experiences. The program was provided through face-to-face teaching at the time of discharge, counseling sessions over the telephone, and a home visit. Subjects also learned about parenting skills using a videotape developed by the research team. Sixteen primiparas were recruited to the experimental group at one hospital in Kyongi province, and fifteen primiparas who were matched according to socioeconomic status were recruited to the control group at a postpartum care center in the same province. Results: Subjects in the experimental group demonstrated significantly higher maternal confidence and mother-infant interaction than those in the control group. Conclusion: The maternal self-efficacy promotion program appears to be an effective nursing intervention for parenting of first-time mothers in Korea.

The purpose of this study was to investigate the changes in infant-mother interactions and to measure infant-mother interaction, mutuality, and reciprocity at the 2nd and 6th postnatal monthperiods. Infant-mother interaction was assessed in the mornings, afternoons, and evenings in the 2nd and 6th postnatal months, by filming unstructured free play in the home and analyzing 28 of these infant-mother film recordingsusing two trained observers. This study can be summarized in five points. First, the separate frequency distribution of each category in MIIBR's maternal behavior was as follows: the frequencies of vocalization category, the kinesthetic exercise & physical contact category, the physical caregiving category, and theuse of play tool category. These all showed changes in the 6th postnatal month compared to the 2nd postnatal month. Second, the separate frequency distribution of each category in MIIBR's infant behavior was as follows: the frequencies of physical behavior category, the vocalization category, and the play behavior category. These also all showed changes in the 6th postnatal month compared to the 2nd postnatal month. Third, the mutuality and reciprocity of mother interaction decreased in the 2nd postnatal month compared to the 6th postnatal month. Fourth, mutuality and reciprocity in the infant interaction increased in 2nd postnatal month compared to the 6th postnatal month. Fifth, mutuality and reciprocity in the infant-mother interaction increased in 2nd postnatal month compared to the 6th postnatal month. In conclusion, it is evident that infant-mother interactions change over time. This study bears particular significance in setting a foundation for the theoretical basis of the interaction between infant and mother by observation.

This study evaluated the effect of a mother wavelet in the wavelet analysis of various times series made by combining white noise and/or sine function. The result derived is also applied to short-memory arctic oscillation index (AOI) and long-memory southern oscillation index (SOI). This study, different from previous studies evaluating one or two mother wavelets, considers a total of four generally-used mother wavelets, Bump, Morlet, Paul, and Mexican Hat. Summarizing the results is as follows. First, the Bump mother wavelet is found to have some limitations to represent the unstationary behavior of the periodic components. Its application results are more or less the same as the spectrum analysis. On the other hand, the Morlet and Paul mother wavelets are found to represent the non-stationary behavior of the periodic components. Finally, the Mexican Hat mother wavelet is found to be too complicated to interpret. Additionally, it is also found that the application result of Paul mother wavelet can be inconsistent for some specific time series. As a result, the Morlet mother wavelet seems to be the most stable one for general applications, which is also assured by the recent trend that the Morlet mother wavelet is most frequently used in the wavelet analysis research.

Objective: The goal of this study were (1) to examine the type of parental time, (2) to investigate the family's characteristics that affect the parental time types. (3), to identify the differences in time satisfaction and time deficit according to the types of parental time of mothers with preschool children. Methods: The data source for this research was the 2014 Time Use Survey conducted by the Korea National Statistical Office(391 time diaries). Data were analyzed using K-means cluster analysis, multinominal regression, and ANOVA. Results: The results can be summarized as follows. First, parental time was classified into four groups; non-participation, play-centered, physical care-centered, unspecified group. Second, the characteristics of each type depended on children's age, mother's education level, mother's income, and dual earner families. Third, time deficit showed significant differences between play-centered and non-participation type. Conclusion/Implications: Based on the results, implications for policy regarding child care and labor were suggested.

Purpose: This study aimed to compare breast milk minerals between mothers with gestational diabetes mellitus (GDM) and healthy mothers. Methods: This study was a short-term prospective study to determine the difference in milk minerals of 30 GDM mothers and 30 healthy mothers. Mineral concentrations in breast milk were measured for Na, K, Ca, Mg, and P. The first breast milk was collected on the 5th day after childbirth, while the second one was collected on the 14th day. For the variation of mineral content of breast milk over time between groups, generalized estimation equations were used. Results: The mean age of the GDM group and healthy mother group was 32.56 and 31.17 years old, respectively. Na was significantly higher in GDM mother group (Wild 𝛘²=4.35, p=.037) over time (Wild 𝛘²=21.59, p<.001), and Ca was significantly higher in healthy mother group (Wild 𝛘²=1.77, p=.018) over time (Wild 𝛘²=19.09, p<.001). Mg, P, and K showed a significant difference in time (Wild 𝛘²=18.12, p<.001; Wild 𝛘²=7.73, p=.005; Wild 𝛘²=7.10, p=.008). P was significantly higher in GDM mother group on 5th day of delivery (t=2.08, p=.042). Conclusion: There was a difference in the mineral composition of breast milk between GDM mothers and healthy mothers. Therefore, it is necessary to develop and apply intervention programs such as effective prenatal blood sugar management and postpartum breast massage considering the characteristics of GDM mothers.

Objective: Transmission of S. mutans, a major dental caries pathogen, occurs mainly during the first 2.5 years of age. Children appear to acquire S. mutans mostly from their mothers, but few studies have investigated preventive effect of xylitol to S. mutans transmission from mother to child. The aim of this study was to perform a follow-up evaluation the preventive effect of xylitol chewing gum of the S. mutans of children's oral cavities, which included the characteristics of vertical transmission from mother to child. Methods: The mothers voluntarily participating in a women's oral health prevention program were divided into two groups (a control and a xylitol group). The subjects were 20 mother-child pairs, who were monitored for 30 months. Xylitol chewing gum group had consumed 2 gum pellets, 3 times a day for 24 months, and then they were followed until 30 months. At baseline, 24 and 30 months whole stimulated saliva samples were collected from the mothers. Children were also recruited from 6 months to 30 months after birth and were collected their dental plaque samples. After isolation and identification, the analysis of the colony count, transmission electron microscopy and real-time RT-PCR were performed to analyze the characteristics of S. mutans. Results: The S. mutans counts decreased steadily in the xylitol group at 24 months, but increased at 30 months. The similar results were showed at their children. While the glucan synthesis was decreased at xylitol group both mother and child. The expression of gtfB, gtfD and ftf were significantly reduced in the xylitol group both mother and child (p<0.05). Conclusions: These findings indicate that chewing xylitol gum over a long period may decrease the expression of the genes associated virulence and reduced the glucan synthesis of S. mutans, which can result the preventing the mother-to-child transmission of S. mutans.

The survey on feeding practice in 202 infants in Kwangju area was undertaken from April to May, 1993. The incidence of breast feeding was 35.6% of the interviewed mothers while 35.1% of infants were formula fed. Baby's sex, birth order, birth weight and mother's educational level did not affect the infant's feeding method of the respondents , but family's monthly income affect it significantly(p<0.05). Initiating time f weaning in infants was 4.83 month. Fruits and fruit juice, infant's most favorite food were the first food introduced to infants. Cereal's were offered frequently as infant foods while animal protein source and vegetables were lesser used 52.8% of mothers purchased commercially prepared infant food , while 33.2% of them did not use it at all. Depending on mother's educational level, mother got information on weaning with the aid of different education materials. The respondents were most interested in the way how to prepare weaning food. It might be suggested that development of effective nutrition education technique specific to the different groups of mothers should be focused.

Purpose: To investigate the effect of a maternal role adjustment program on first-time mothers. Methods: The research was quasi-experimental with a non-equivalent control group non-synchronized design. Participants were first-time mothers admitted to two postpartum clinics at women's hospitals. The experimental group had 38 mothers and the control group had 35 mothers. A maternal role adjustment program was applied individually to the experimental group between the 1st and 2nd weeks after childbirth. Assessing Adaptation to Motherhood, Semantic Differential Scale-Myself as Mother, and Edinburgh Postnatal Depression Scale were used to measure effects of the program. A pre-test was conducted in the 1st week after childbirth while post-tests were conducted in the 4th and 6th weeks. Data were analyzed with $x^2$ test, Fisher's exact test, t-test, and repeated measures ANOVA using SPSS 24.0. Results: Maternal role adjustment (F=6.17, p=.015) and maternal identity (F=6.63, p=.012) were significantly increased in the experimental group compared to those in the control group. However, the difference in postpartum depression (F=1.11, p=.335) was not statistically significant between the two groups. Conclusions: The maternal role adjustment program can be utilized as an effective nursing intervention program to enhance maternal role adjustment and maternal identity for first-time mothers.

The purpose of this descriptive study was to investigate the determinants of mother's choice of infant feeding method on immediate postpartum period & the breast feeding practice after 1, 2, 3, 4, 5months. The subjects were 170 mothers who were delivered at 2 hospital, 2 OBGY clinics, 1 midwifery in Jinju, the data were collected from Jan. 1 to Feb. 20 of 1991, form each subject at two periods of time ; postpartum 2 or 3 days via interview, 5months via telephone interview. The results were as fellows : 1. The propotion of mother planned exclusive breast-feeding was 66.5%, milk feeding 17.6%, mixed feeding 15.9%, End 38.9% of mothers planned to breast-feed their infants for 4-6moths, 25.7% for more than 12 months. The major reasons for selection of milk feeding method were the presence of mother's job(26.7%), the conditions of breast & milk production(23.7%). 2. There were significant relations between the choice of feeding method & the presence of s job(p<.01), & parity(p<.01). 3. The percentages of subjects that were received education about the advantages & method of breast feeding were 63.5%, 38.2%, respectively, & the informants were mass media, 89.8%, 81.5%. 4. The most of mothers had the knowledge about the advantages of breast feeding. 5. The percentage of mothers that practiced breast feeding on postpartum were 75.9%. 6. The rates of breast feeding practice by duration were more than 5months, 60.5%, 1 month, 27.1%, 2-4 months. 12.3%. 7. The reasons for the stop of breast feeding were the decrease of milk volume(22.9%), the presence of mother's job(17.4%). 8. The duration of breast feeding practice were differed significantly by the presence of mother's job, type of delivery, rooming-in, planned duration of breast feeding, the first feeding time.

In order to investigate correlation between mother's dental ca re for her children and their dental caries, this study was conducted wi th the dental examination record of 365 children who showed the same number of questionnaires with those examined for dental conditions and questionnaires written by mothers among children between three and six years of age and their mothers in Yeoncheon, Gyeonggi province in June 2004 to estimate frequency and percentage of general properties of subjects and mother's oral health care behaviors for her children by research items, to carry out cross-tabulation analysis and correlation analysis following Chi-square distribution for the presence of dental caries in deciduous teeth and oral health care behaviors, and to use decision tree analysis among data mining techniques for those factors associated with the presence of dental caries in deciduous teeth, and drew the following conclusions. 1. For mother's oral health care behaviors and attitudes for her children, 225 mothers(61.6%) confirmed their children's teeth-brushing; 278(76.2%) used no fluorine; and 286(78.6%) observed their children's teeth, 322 mothers(88.2%) instructed their children in teeth-brushing while 268 (73.4%) provided dental care, 232 mothers(63.7%) treated their children's cavity; 290(79.4%) believed that their children had good dental conditions; and 294(80.5%) answered that they began to provide their children with dental care in deciduous teeth. 2. As for the presence of dental caries in deciduous teeth and dental health care behaviors, there were statistically significant differences in employment, confirmation after teeth-brushing, teeth observation, instruction in time for teeth-brushing, use of fluorine, cavity treatment, time for dental care, and perception of dental conditions(p<0.05). 3. As for correlation between dental caries in deciduous teeth and oral health care behaviors, mothers who worked, who believed that their children didn't have good dental condition, and who thought that it was necessary to begin to provide dental care in permanent teeth were found to get their children to suffer from dental caries in deciduous teeth. Besides, those who failed to confirm teeth-brushing, who used no fluorine, and who failed to observe teeth and gave no instruction in time for teeth-brushing were shown to get their children to suffer from dental caries in deciduous teeth. 4. Variables to determine the presence of dental caries in deciduous teeth were classified by cavity treatment, mother's employment, time for dental care, and observation of children's teeth. The first node to determine the presence of dental caries in deciduous teeth was found to be cavity treatment; the next criteria for classification after cavity treatment were shown to be mother's employment and time for dental care. In case of children with no cavity, they were found to be mother's employment and teeth observation.
