  • In general, a fault locator is installed in Sub-Station of AT(Auto-transformer) feeding system to estimate the fault location and to protect the Korean AT feeding system. Since the line impedance characteristic is different to normal 3-phase transmission line, we need particular modification factors, which can be calculated using fault location recording data, to estimate the accurate fault location. Up to recently, forcible ground test has been used to calculate the modification factors of the fault locator. However, large amount of current is occurred when the forcible ground test is performed, and this current affects to adjacent equipments. Therefore, we proposed a novel calculation method of modification factors, arbitrary trip test, using boosting current of the operating electric train. Through several field test, we confirmed that modification factors for fault locator can be easily calculated by using proposed method. Moreover, we verified the accuracy and stability of the proposed calculation method.

  • The forming limit diagram of tube is required for the part design and the formability analysis of tube hydroforming. The finite element analyses of simple bulge test were done to obtain the various strain combinations on FLC. The finite element analysis results were shown that the bursting at various strain combinations could be induced by simple bulge test. The experiment oi tube bulge test was carried out according to the test condition that obtained from finite element analysis and the left hand side of forming limit diagram was built.

  • The purpose of this study was to investigate the relationship between knowledge of breast feeding and practice of feeding pattern. A sample of 117 mothers who have the babies between age from 1 month to 12 months were selected from one university hospital and one public heath care center in J city. The data were collected with the questionnaire during the period from the January. 5, 2002 through January. 30, 2002. Analysis was done by using frequency, percentage, t-test, analysis of variance, and scheffe test. The results of this study can be summarized as follows. Comparision of the method of feeding by general characters. Income state, rearing (p=.019), rearing supporters(p=.026), infant age(p=.03) have shown significant difference as the variables affecting Breast practice rate. Breastfeeding rate were 24.8%, mixedfeeding type, 14.5%, milkfeeding type, 60.7%. The mean of knowledge on breastfeeding by feeding patterns were the highest in the group of breastfeeding. There was statistical significance between the group of breast feeding and milkfeeding(p=.000). In the conclusion, this study revealed that knowledge of breastfeeding promoted practice of breastfeeding. Therefore, to promote practice of breastfeeding, it is necessary that nurses provide adequate information about knowledge of breastfeeding.

  • The purpose of this study was to investigate feeding difficulty and its influencing factors of elders with dementia in long-term care facilities. Participants were 158 elders with dementia residing in three nursing facilities. Data were collected from Aug. 18 to Sep. 12 in 2014. The feeding difficulty in dementia scale, Korean version-Activities of Daily Living and Mini-Mental State Exam-Korean version were used as instruments. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation and stepwise multiple regression by SPSS 17.0. Mean feeding difficulty score was $0.62{\pm}0.43$(range of 0-2). The highest feeding difficulty item was "patient require close supervision while feeding". The variables influencing the feeding difficulty was ADL(${\beta}=.312$), cognitive function(${\beta}=-.172$) which explained about 20.0% of total variance. The results suggest the need of developing feeding difficulty coping strategy according to dietary behavior phase, In addition, the development and testing the educational program for caregivers to help feeding difficulty of the elders with dementia in long-term facility are recommended.

  • The purpose of this study was to investigate the differences of knowledge and attitude level of breast feeding between breast feeding mothers and bottle feeding mothers. The subjects were mothers of 65 infants 1-6 months of age. Data were collected by a questionnaire on knowledge of breast feeding developed by Jung et al.(l994) and on attitude of breast feeding developed by Shin and Jeon(l996). The data was statistically analyzed according to Frequency, t-test, ANOVA and Pearson correlation coefficients. The results are as follows. 1) Degree of knowledge of breast feeding was significantly different according to child number(F=3.72, P<0.05) and delivery pattern(T=2.28, P<0.05) in breast feeding mothers. 2) There was a Significant difference on knowledge of breast feeding between breast feeding mothers and bottle feeding mothers(t=2.34, p<.05). 3) There was a statistical Significant difference on attitude of breast feeding between breast feeding mothers and bottle feeding mothers(t=3.05, p<.01). 4) The correlation between the mother's knowledge and attitude level of breast feeding was not found. Based on the results of this study, we suggest that systematic and supportive breast feeding program including knowledge and attitude of breast feeding have to be provided by nurse to mothers of infants to take an important role in breast feeding.

  • Purpose: The objective of this study was to identify the effectiveness of continued breast feeding and maternal identity between rooming-in and not rooming-in groups of mothers in post partum care. Method: The subjects were selected by convenient sampling, with 95 women in childbirth completing a questionnaire. The data were collected on the 2nd day after delivery by questionnaire, and after the 4th and 8th weeks by telephone interview. Measures used in this study included general characteristics, breast feeding related characteristics, and the maternal identity scale revised by Koh(1996). The data were analyzed with the SPSS program, and the Chi-test and t-test were used to identify the effect on breast feeding and maternal identity. Results: Continued breast feeding up to 4 weeks after deliverly was not statistically significant between rooming-in and not rooming-in group, but beyond 8 weeks of deliverly, it was significantly different in rooming-in group(p<.01). Maternal identity was significantly higher in rooming-in group than in not rooming-in group(<.01). Conclusion: Mothers preferred rooming-in system because it helped breast feeding and baby care. Rooming-in system provides self confidence in taking care of baby, knowledge about breast feeding and stimulates early phase lactation. We recommend rooming-in system in hospitals to promote breast feeding and maternal identity. Nurses are encouraged to discuss prenatal breast feeding before delivery and rooming-in care should be planned individually for continuation of breast feeding and formation of maternal identity.

  • Purpose : The present study examined the etiology and risk factors of the early breast-feeding jaundice and the usefulness of auditory brainstem response test as early predictor of kernicterus. Methods : Medical records of neonatal jaundice in newborn admitted to Daegu Fatima Hospital between September 2005 and May 2006 were analyzed prospectively. Infants were grouped according to feeding method : breast feeding group (breast feeding only, n=23), mixed feeding group (breast feeding mainly plus addition of fomula feeding, n=13). Results : There were no significant differences in gestational age, birth weight, sex, duration of phototherapy, serum bilirubin and hemolytic evidence between the two study groups. First visiting day of life at out patient department was significantly delayed in breast feeding group ($8.7{\pm}3.6day$) compared to mixed feeding group ($6.0{\pm}1.9$) (P=0.009). Weight loss was significantly severe in breast feeding group compared to mixed feeding group (P<0.05). In auditory brainstem response test, loss of Wave V in 3 cases was observed and recoverd after blood exchange transfusion in follow up test.Wave III latency had significant correlation to serum bilirubin in auditory brainstem response test (70 dB) (P=0.002). Conclusion : Our study suggest that further education about breast feeding and follow up within the first postnatal week would be necessary for early detection and prevention of early breast-feeding jaundice. Test of serum bilirubin and auditory brainstem response would be helpful in determination of blood exchange transfusion.
