The purpose of this study is to understand the relation of peer group caring interaction, Professional self-concept, and Nurses' Retention. The subjects of this study are 133 nurses who have worked for more than three months at five general hospitals with more than 300 beds in S city. As a result of the study, nurses' retenstion was higher than those of under 25 years of age between 30 and 35(F=3.313, p=.039).The professional self-concept of hospital nurses has been identified as an influence factor of intent to serve. Professional self-concepts have been shown to be better with higher peer-care and consideration(r=.397, P=.004). The peer group caring interaction behavior can occur not only between colleagues but also between managers. Therefore, it is necessary to proceed with the manager's group caring interaction as a follow-up study.

Purpose: This study was done to develop a new nursing intervention, Meridian Massage, and to investigate its effect on weight in infants and mother-infant interaction. Method: This study was conducted using a quasi experimental non equivalent control group pretest-posttest design. Thirty-one newborn infants from a postpartum Management Center were selected and assigned to two groups, experimental and control. Data were collected from February 1 to September 30, 2004. Infants in the experimental group (16) were given Meridian massage for 15 minutes daily for 6 days and weighed every day at 10 am. Using the Nursing Child Assessment Feeding Scale(1978), mother-infant interaction was determined before the treatment, after 1 week and 1 month after the massage. Results: Infants in the experimental group had a higher average weight than those in the control group and the difference was significant (Z=-2.29, p=.022). For mother-infant interaction, the experimental group had higher scores tHan the control group, and the difference was significant between both the two groups, and the 3 measurement times. Conclusion: The Meridian Massage in this study showed positive weight gain and positive mother-infant interaction. This study shows that meridian massage is an effective nursing intervention in improving infant development.

Purpose: The purpose of this study was to identify the effectiveness of sensory stimulation program administered by primipara on the physical growth and mother-infant feeding interaction for the first 6 months of infancy. Method: Data were collected from December 1, 2001 to June 30, 2003. A total of 35 mothers and their infants were assigned to a control(n=17) and an experimental(n=18) group. Mothers in the experimental group received education related to sensory stimulation program and administered to their infants twice a day for 6 months. Both groups were measured the weight, length, head circumference and chest circumference of infants at 6 weeks, 10 weeks, 14 weeks, 18 weeks, and 22 weeks and the mother-infant feeding interaction at 6 weeks, 10 weeks through the home visiting. Result: Compared to the control group, the experimental group had significantly larger increases in head circumference for intervention period. In addition to, the experimental group showed significantly higher score in mother-infant interaction than control group. Conclusion: These data suggested that sensory stimulation program administered by primipara may improve the physical growth of full term infant and mother-infant feeding interaction.

본 연구에서는 깊은 기초의 내진설계에 적용하기 위해, 지진하중에 의한 말뚝기초의 응답을 산출하여 비교, 검토하였다. 본 연구에서 사용된 해석 방법은 Subgrade Reaction Theory 및 탄성해석법과 같은 유사정적 해석방법, Prakash및 Gazetas가 각각 제안한 동적 해석방법이며, 예제해석을 통해 말뚝의 최대 상대변위 및 최대 휨모멘트를 위의 각 방법을 이용해서 산출하였고, 그 결과를 각각 비교하였다. 또한 말뚝의 군효과를 근사적으로 고려하여 Novak에 의해 수행된 실험 결과와 비교하였다. 해석결과를 분석해 볼 때 Kaynia와 Kausel이 제안한 동적 Group Interaction Factor Approach 에 의한 땅법 및 Gazetas가 제안한 방법의 최대 상대변위는 실측치와 부합하게 산정되었으며, Prakash 가 제안한 방법과 정적 Group Interaction Factor Approach에 의한 변위 및 휨모멘트는 과대평가되었다. 그러므로, 말뚝의 내진설계시에 동적 Group Interaction Factor Approach와 결합한 유사정적해석 을 사용하고 Gazetas가 제안한 동적방법에 의해 이를 검토하는 것이 바람직하다.

Purpose. The purpose of this study was to test the effects of infant massage (auditory (mother's voice), tactile/ kinesthetic (massage) and visual (eye to eye contact) stimulation) on weight and height of infant and mother-infant interaction with normal infants over a period of 4 weeks. Method. This study was designed as a nonequivalent control group pretest-posttest design. The experimental group infants (aged 2-6 months) participated in one of the infant massage programs at the health district center for 4 weeks. The control group (N=26) was paired with the experimental group (N=26) by matching the infant's age and sex. Infant weight, height, and mother-infant interaction were measured two times and recordings of the mother-infant interaction were done using the video equipment in a room at the health center for 10 minutes. Results. After 4 weeks of massage, there were no significant differences weight gain and height increase between the two groups. Comparison of the total scores for the mother-infant interaction between the two groups showed a significant difference (t=5.21, p=.000). There were also significant differences on maternal response (t=3.78, p=000), infant response (t=5.71, p=000) and dyadic response (t=4.05, p=000) in the mother-infant interaction between the two groups. Conclusion. Overall, the results of this study reassure that infant massage facilitates the mother-infant interaction for infants and mothers who give massage to their baby.

We established a thermodynamic framework of group contribution method based on modified double lattice (MDL) model. The proposed model included the long-range interaction contribution caused by the Coulomb electrostatic forces, the middle-range interaction contribution from the indirect effects of the charge interactions and the short-range interaction from modified double lattice model. The group contribution method explained the combinatorial energy contribution responsible for the revised Flory-Huggins entropy of mixing, the van der Waals energy contribution from dispersion, the polar force, and the specific energy contribution from hydrogen bonding. We showed the solvent activities of various polymer solution systems in comparison with theoretical predictions based on experimental data. The proposed model gave a very good agreement with the experimental data.

This study used Family Group Theraplay (Munns, 2005) to investigate the effects of enhancing interaction between child and mother on mitigating developmental risks for children growing up in low-income households. The subjects for the study were selected from among Community Child Care Centers and Community Welfare Centers in Seoul. The children were in the first, second, and third grades of elementary school. Eleven child-mother dyads participated in Family Group Theraplay once a week for a total of 12 45-minute sessions. The control group consisted of 9 child-mother dyads. The Family Group Theraplay program improved interaction between the children and their mothers and also reduced children's behavior problems and mothers' parenting stress.

Crowd behavior analysis research has revealed a central role in helping people to find safety hazards or crime optimistic forecast. Thus, it is significant in the future video surveillance systems. Recently, the growing demand for safety monitoring has changed the awareness of video surveillance studies from analysis of individuals behavior to group behavior. Group detection is the process before crowd behavior analysis, which separates scene of individuals in a crowd into respective groups by understanding their complex relations. Most existing studies on group detection are scene-specific. Crowds with various densities, structures, and occlusion of each other are the challenges for group detection in diverse crowded scenes. Therefore, we propose a group detection approach called Collective Interaction Filtering to discover people motion interaction from trajectories. This approach is able to deduce people interaction with the Expectation-Maximization algorithm. The Collective Interaction Filtering approach accurately identifies groups by clustering trajectories in crowds with various densities, structures and occlusion of each other. It also tackles grouping consistency between frames. Experiments on the CUHK Crowd Dataset demonstrate that approach used in this study achieves better than previous methods which leads to latest results.
