  • This was a pre-experimental study to confirm the breast-feeding ability and effect of follow up care on the breast-feeding rate and the breast-feeding method by the mother-infant breast-feeding assessment tool for the mothers who got the breast-feeding education. The subjects were 46 mothers who experienced normal delivery of infants at a college hospital in K-city, Kyungsangbuk-do, from July 1 to October 21, 2000. The instrument for data obtainment were The Mother-Infant Breast-Feeding Assessment Tool of Johnson et al. (1999), and The Breast- Feeding Method Measurement Tool of Jeong, Geum-hee(1997). This instrument was reliable, showing Cronbach $\alpha$.751. This study classified them into 3 groups: at high risk for breast-feeding failure, at risk for breast-feeding problems, and at low risk for breast-feeding failure by the mother-infant breast-feeding assessment tool on the day of discharge from the hospital after delivering individual breast-feeding education to the subjects. This study investigated the breast-feeding rate and the breast-feeding method through mail questionnaire at the four week after childbirth, and through the phone counselling and the home visit for follow up care at the first week and the second week after childbirth. The sixth week after childbirth, this study investigated the breast-feeding rate by phone. The data analyzed the hypothesizes by $x^2$-test, paired t-test, ANOVA, Wilcoxon signed rank test, Wilcoxon rank sum test and trend analysis using SPSS/PC+ WIN 10.0 program. The results were as follows : 1) Hypothesis 1-1, "there won't be any difference the breast-feeding rate of a group at risk for breast-feeding failure by the time elapsed" was supported through constant the breast-feeding rate, because changes in the breast-feeding rate by the time elapsed after childbirth wasn't statistically significant(t= -1.501, p=.270). Hypothesis 1-2, "there won't be any difference the breast-feeding rate of group at low risk for breast-feeding failure by the time elapsed" was supported through constant the breast-feeding rate, because changes in the breast-feeding rate by the time elapsed after childbirth wasn't statistically significant(t=-1.732, p=.225). 2) Hypothesis 2-1, "there won't be any difference between the breast-feeding method of group at risk for breast-feeding failure for four weeks after childbirth and just after childbirth” was rejected, because the mean point of post test appeared to be higher than that of pre test(t=-7.267, p=.000). Hypothesis 2-2, "there won't be any difference between the breast-feeding method of the group at low risk for breast-feeding failure for four weeks after childbirth and just after childbirth" was rejected, because the mean point of post test appeared to be higher than that of pre test(t=-2.501, p=.012). 3)The 3rd hypothesis, "there won't be any difference between breast-feeding method of groups at risk for breast-feeding problems and at low risk for breast-feeding failure at the 4th week after childbirth and just after childbirth" didn't show any difference between the breast-feeding method of groups at risk for breast-feeding problems and at low risk for breast-feeding failure in the advance test(t=-1.521, p=.130) but there was difference between them in post test (t=-2.012, p=.044). As a result, the 3rd hypothesis was supported by pre test, but it was rejected by post test. In conclusion, this study confirmed breast- feeding education and follow up care just after childbirth were effective for the breast-feeding rate and method. Accordingly, it is proposed that successful nursing intervention of breast-feeding to be necessary by continuously providing follow up care through the mother-infant breast-feeding assessment tool as well as to execute individual breast-feeding education to mothers just after childbirth.

  • Purpose: This study was done to identify the effects of individual postpartum breast-feeding education on adaptation, attitude and practice of breast-feeding in primiparas. Methods: A quasi-experimental nonequivalent design was used to examine the effects of individual postpartum breast-feeding education among primiparas. The data were analyzed using $x^2$-test, Fisher's exact test and paired t-test. Results: There was a significant difference in breast-feeding adaptation (t=-12.94, p<.001), breast-feeding attitude (t=-2.71, p=.011) and breast-feeding practice ($x^2$=16.47, p<.001) between the group education (experimental group I) and individual education after group education (experimental group II). Conclusion: The results indicate that individual education on breast-feeding compared to group education has more positive effects on increasing breast-feeding adaptation, attitude and practice in primiparas. This result also indicates that many primiparas should be given opportunities of various types of education to improve breast-feeding practice such as individual approaches and postpartum breast-feeding education programs.

  • Purpose: This study aimed to elucidate the prevalence of breast feeding and maternal psychosocial predictors affecting the breast feeding practice at six months postpartum. Method: One hundred and sixty one mothers at six months postpartum were conveniently recruited in two public health center in Jeju-city. Subjects completed a well-structured questionnaire regarding the feeding types of the child, maternal self-esteem, the Edinburgh Postnatal Depression Scale (EPDS), husband support, and marital adjustment scale. The data was analyzed using the $X^2-test$, t-test, Pearson correlation coefficients, and logistic regression. Result: The prevalence of breast feeding at six months postpartum was 29.9%. Predictors of breast feeding practice identified by the logistic regression analysis include first feeding type after delivery, marital adjustment, readiness for maternal role and work state. Conclusion: The prevalence of breast feeding practice was lower than WHO desired at six months postpartum. Therefore, the findings support the need for breast feeding education including interventions focused on improving readiness for maternal role and marital adjustment.

  • The development process of KSR-III propulsion feeding system is subscripted. The purpose of propulsion feeding system is to feed a certain amount of propellant from propellant tank to engine by the end of combustion. Pressure-fed liquid rocket, KSR-III has the unique characteristics of both pressure regulator and cavitation venturi as a passive flow control device. Main parameters of feeding system are confirmed by both water test and CFD(전산유체) technique. Flow control effect with venturi is confirmed by water test. Initial stabilization characteristic of pressure regulator is confirmed by real propellant test. And, to avoid the effect of resonance between rocket and feeding system, this article deal with POGO(포고) analysis to the feeding system.

  • This study was conducted to evaluate the industry foodservice management practices and to suggest guidelines for the effective foodservice management. The survey for the analysis was conducted through the questionnaires to dietitians. They were divided into two groups : the site color worker and the blue color worker. The questionnaires were received for a response rate of 73.2%. Statistical data analysis was completed using the SAS programs for descriptive analysis, $x^2$ test, T-test, F-test, and Fisher's LSD. The results of the study can be summarized as follows : 1) The level of education of dietitians and food cost in the employee feeding operations for the blue color worker was lower than the employee feeding operations for the white color worker. 2) The labor productivity indices were not significantly different according to types of workers. But in the employee feeding operations for the blue color worker, full-time foodservice employees worked more than 10.7 hour per week than their counterpart. This indicates the full-time foodservice employees in the employee feeding operations for the blue color worker performed more loaded work compared to the employee feeding operations for the white color worker. 3) Equipped rate of facilities in the employee feeding operations for the blue color worker was low especially in the food preparation and cooking processes.

  • Purpose: To investigate the impacts of individualized versus group prenatal breast-feeding education on postnatal breast-feeding knowledge, this study addressed techniques and rates of first-time mothers as part of data collection for developing breast-feeding education programs. Methods: A quasi-experimental nonequivalent control group design was applied to compare the effects of prenatal breast-feeding individual vs. group education among first-time mothers. Collected data was analyzed using $x^2$-test, t-test, paired t-test, and ANOVA. Results: There was no difference on the knowledge of prenatal breast-feeding between individual and group education. However, individual education was a more effective method than group education on post-natal knowledge. In the 4th and 8th weeks of breast-feeding, individual education was more effective than group education. However, there was no difference between the two education methods at Week 12. Conclusion: This study indicates that many outpatient mothers should be given various individual approaches and prenatal breast-feeding education programs to provide them with opportunities for education to improve breast-feeding rates. However, there was no statistically significant difference in the breast-feeding rates at Week 12, which may be attributed not to education methods but to changes in external environmental factors. Further research is needed to address the changes.

  • This study was attempted to identify the knowledge to breast-feeding and the performance of nursing activities for breast-feeding and to test 'how does the degree of knowledge to breast-feeding influence the nursing activities for breast-feeding?' The subjects were 180 nurses working in delivery rooms, nursery, obstetrics & pediatrics wards or OPD of obstetrics & gynecology of 8 general hospitals in Pusan as of August 3 through 13, 1996. The results are abstracted as follows. 1) Subject nurses' age, 25-29 was 45.6%(the major), education levels graduates from junior college were 95.0%, unmarried status was 62.2%, 76.5% of married nurses had children, 39.7% in-service education for Breast-Feeding, 33.7% did nursing activities for breast-feeding actively, the reason for inadequate activities for breast-feeding was 'too much other tasks.' 2) The degree of knowledge to breast-feeding ; mean score was 13.54, the degree of performance of nursing activities for breast-feeding : 92.38±20.93 points out of possible 145 points (3.19±.74 out of possible 5 points) moaned that it was a low level. 3) The hypothesis 'the nurses who have higher degrees of knowledge to breast-feeding will show higher degrees of performance of nursing activities for breast-feeding than the nurses who have lower degrees of knowledge to breast-feeding' was tested by t-test(t=-.01, P=.9888), but rejected because it turned out statistically not significant at the level of P<.05. Above results suggested the degrees of knowledge to breast-feeding and the degrees of performance of nursing activities for breast-feeding were generally low and the degree of knowledge didn't influence the nursing activities. Researchers believe that the education for breast-feeding by the nurses need to be performed systemically & practically and new method of breast-feeding education program need to include hospital managers as well as nurses related mothers and their family. In audition, researchers propose the introduction of &lactation specialist system&, for the specialist can change the attitude of feeding-mothers positively with their specialty and authority.
