PURPOSE: This study was designed to investigate effect of sensory stimulation on the mother-infant interaction in premature infants. METHOD: The subjects of this study consisted of 36 pairs of premature infants and their mothers from NICU of one university hospital located in Taegu, 18 pairs for intervention group and 18 pairs for control group. The data were collected from May, 1999 to October, 2000. For the intervention group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00-11:00 in the morning and 7:00-8:00 in the afternoon by researcher and mother). To determine mother and infant interaction during feeding, tool developed by Kim Mi-Ye(1999) was used. Collected data were analyzed with SAS program using chi-square test and t-test. RESULT: Significant differences were found in mother-infant interaction between two groups(t=-5.38, p=.00). It indicates that sensory stimulation was effective in improving mother-infant interaction. In the aspects of the quality of mother-infant interaction, sensory stimulation was most effective in improving sensitivity to mother and infant's synchronic behaviors(t=-5.43. p=.00) and followed by growth fostering(t=-5.07, p=.00), sensitivity to infant's cues(t=-4.53, p=.00), clarity of infant's cues(t=-3.03, p=.00) and responsiveness to the mother's behaviors(t=-2.14, p= 0.04). CONCLUSION: Based on the result of this study, it is suggested that maternally administered sensory stimulation should be applied clinical practice to improve interaction of premature infants and their mothers.

Fifty cases of hepatocellularcarcinoma were studied using retrospective flow cytometric(FCM) and image cytometric(ICM) DNA analysis to determine the prevalence of aneuploid cell population and whether they were associated with any particular clinico-pathologic findings. At the same time, we compared the difference between FCM and ICM. The materials were prepared from 50 micrometer cut of paraffin embedded blocks. The DNA modal values, which could be defined in 42 cases by FCM with 74% aneuploidy and in 50 cases by ICM with 76% aneuploidy. So 95% of the cases had concordant DNA ploidy results by both techniques of FCM and ICM. Abnormal DNA pattern was correlated with age(<50), presence of cirrhosis, pathologic grade and some pathologic types(p<0.05), but was not correlated with presence of HBsAg, sex, alphafeto protein, and alcohol history(p>0.05). Also we found that ICM technique was easier to perform and interprete.

PURPOSE: This study was done to investigate the effects of breast-feeding education and support services on rate of breast-feeding three and six months after birth, and the effect on infant's growth (weight, height, body mass index [BMI]). The experimental group which had both education and support services was compared with the control group which had only breast-feeding education. METHODS: This study was a quasi-experimental study with a time-series design. The participants were 39 mothers who were hospitalized for childbirth. Twenty mother were assigned to the experimental group and 19 mothers, to the control group. The breast feeding education was done during hospitalization, and support services were provided once a week after discharge for a month (a total 4 times) by a maternity ward nurse. Data regarding breastfeeding rate at one month after childbirth was collected by phone call; the breast-feeding rates at three and six months after childbirth were collected in a visit to the families. The child's weight and height were also measured during the visit. RESULTS: The experimental group had a statistically significant higher rate for frequency of breast-feeding at one, three and six months after childbirth than the control group. However, there was no meaningful difference between the two groups for infant growth. CONCLUSION: The results of this study suggest that breast-feeding education is helpful for a start, but support services are also necessary to sustain breast-feeding.

The understandings of the characteristics of eccentric exercise are very important because all sports and daily activities under the gravity force should be well coupled between concentric contraction and eccentric contraction as accelerator and decelerator respectively. We tested 40 knee flexors and extensors of 20 normal young persons at different anglular velocities of 60o/sec and 120o/sec using Cybex 6000 (A division of Lumax, New York) isokinetic dynamometer in order to know the characteristics of eccentric isokinetic contraction parameters by comparing with concentric isokinetic parameters. Compared to the concentric isokinetic contraction, eccentric isokinetic the peak torque and average power values of knee extensor and flexor muscles showed negative values which means that eccentric contractions were coupled with concentric contractions as decelerator and energy absorptioner. The peak torque values of eccentric contraction were 38 - 61%, 44 - 79% higher in flexor and extensor, respectively than those of concentric contraction and not so decreased as the peak torque of concentric contraction decreased in high angular velocity. The average power values of knee flexor and extensor muscles were definitely low in eccentric contracton than those of concentric contraction but were increased simultaneously with high angular velocity contraction. Further studies about the velocity dependency, muscle soreness, methodology to measure real eccentric activities and other parameters of eccentric contraction are needed imminently.
