Purpose: This study was done to investigate effects of Meridian massage on the growth of the infant and on mother-infant interaction, mother-infant attachment, and the mother's satisfaction with her mothering role. Method: The participants were 39 mothers of infants who were seen at one of two urban public health centers located in Yangju or Seoul. Data were collected from February 2008 to December 2008. Infants in the experimental group were given Meridian massage for 50 minutes (lecture 20 minutes, practice 15 minutes, preparation and arrangement 15 minutes) once a week for 6 weeks. Percentages, means with standard deviation, $X^2$-test, repeated measured ANOVA, and ANCOVA were used with the SPSS program to analyze the data. Results: Infants in the experimental group showed an increase in weight & height compared to those in the control group. Mother-infant interaction, mother-infant attachment, and satisfaction with mothering role were significantly higher in the experimental group than the control group. Conclusion: The above finding suggest that Meridian massage should be applied in clinical practice to improve growth of infants, interaction and attachment between infants and their mothers, and the mother's satisfaction with her mothering role.

The intent of this longitudinal descriptive correlational study is to investigate the change of the mother - infant interactions over the periods of one month, three months and six months of the infant's age. This study is also intended to explore the interrelationships among three major factors- the perception of pregnancy, the mother -infant inter-action and the maternal attitude. The samples participated are 36 pairs of mother and infant from two university hospitals in Seoul. A data collection was made, from October in 1988 to September in 1989, for each subject at five periods of time ; prenatal period (after 36 weeks in pregnancy), postpartum two or three days, one month, three months and six months of infant's age. The research tools used in this investigation are Mother - Infant Play Interaction Scale (MIPIS), Prenatal Self- Evaluation Questionnaire and Cohler's Maternal Attitude Scale. Some of the findings are as follows ; 1. There is a significant increase in the mother - infant interaction from one month to three months and six months of infant's age. The highest score of the mother - infant interaction during three periods is at the time of three months. 2. The primipara's mother -infant interaction is not affected by the demographic characteristics, such as age, education and vocation of mother, types of delivery, or sex of infant. 3. Among seven categories of the perception of pregnancy, the most positively perceived categories by primiparas are acceptance of pregnancy and identification of. a motherhood role : whereas the negative ones are preparation for labor, concern for well -being of self and baby, md fear of pain, helplessness and loss of control in order of negativity. 4. There is no significant relationship between the perception of pregnancy and the mother - infant interactions. 5. There is no significant change in the maternal attitude over the period of one month, three months, and six months of infant's age. 6. There is no significant relationship between the maternal attitude and the mother - infant interactions. 7, The significant relationships are (end between the perception of pregnancy and maternal attitude, especially in the categories of concern for well -being of self and baby, accetance of pregnancy, identification of a motherhood role, fear of pain, helplessness and loss of control, and relationship with husband. In conclusion, it is confirmed that primipara's mother-infant interactions change over time period, and that perception of pregnancy and the maternal attitude do not affect the mother-infant interactions despite a significat relationship between those two variables. The implications of this investigation include a suggestion that nurses need to teach and demonstrate to mothers how to care for and interact with their infants, with a view to improving the mother-infant interactions which can be obtained through the improvement of maternal sensitivity to their infants.

This paper presents animation techniques and issues involved in virtual environments where the participants interact with each other through a network. The state of the participant should be collected at each local site, and broadcasted to the other sites. Because information exchange is minimal, animation techniques are applied to convert the incoming low DOF parameters into high DOF joint angles that completely determine the configuration of the agents at each frame. As a case study, a software system VRLOCO is introduced, which has been developed by the author over the last five years.

This study considered the problem of whether the method of Lamaze education changes maternal attitudes toward childrearing, material-infant interaction and is feasible for Korean culture in nineteen mother. infant dyads. Among those mothers, nine were assigned experimental group who received Lamaze education at the period of 7th and 8th month of gestation, and ten were assigned control group who received obstetric routine care. Maternal attitudes were assessed with selected items from Cohler's Maternal Atttiude Scale. Maternal Play Interaction Scale was used during play session to evaluate maternal sensitivity, infant response and mother-infant dyadic synchrony. There were no significant differences not only between the two groups, but also between the period of pre-lamaze education and post-delivery on the Cohler's maternal attitude scale. Experimental mothers and babies scored significantly higher on maternal sensitivity and infant response. But no differences in mother-infant, dyadic synchrony were found. This findings mean that the effect of the lamaza education on the maternal attitudinal change related to be needed the change of cognitive structure is delayed while the effect of that on the maternal infant behavioral response showed immediatly. Modification of Lamaze method is necessary for practical use in our sociocultural system.

Purpose: This study aimed to identify the factors influencing the interaction between mothers and preschool-age children and construct a structural equation model based on the factors identified. Methods: The data were collected from the mothers of children aged three to six years enrolled in kindergartens in Seoul, Gyeonggi, Chungbuk, and Jeonbuk. A total of 328 questionnaires were used for the analysis. Analysis was performed using SPSS 26.0 and AMOS 26.0 programs. Results: The child's self-regulation (β = .42, p < .001) had the most significant influence on the interaction between mothers and preschool children, followed by the mother's parenting stress (β = - .23, p = .008), social support (β = .17, p < .001), and the child's active temperament (β = .15, p < .001). The child's gender, emotional temperament, social temperament, and mother's education level had indirect influences. Conclusion: These results suggest that interventions considering the child's temperament, mother's parenting stress, and social support are required to promote the interaction between preschool-age children and mothers.

Last 20 years have witnessed many studies dealing with effects of elevated $CO_2$ on terrestrial ecosystems. However, fewer efforts have been made to elucidate effects on wetland ecosystems, although they play a key role in global biogeochemical cycles. This review synthesizes published data to reveal effects of elevated $CO_2$ on wetland plants. In particular, we focused on the changes in primary production, community structures, evapotranspiration, and nutrients in plants. Many studies have reported increases in primary production in individual plants, but we could not conclude that this will lead to increases in carbon sequestration in wetland ecosystems. The reasons include transport of photosynthates into belowground parts, speciesspecific responses, interaction among different species, and limitation of other nutrients. However, elevated $CO_2$ increased transpiration rates in many wetland plants, suggesting substantial influences on water budgets of wetlands. In addition, similar to terrestrial ecosystems, elevated $CO_2$ increased C/N ratio of many plants, which may impede organic matter decomposition in the long term. However, further information on dynamics of belowground carbon supplied from wetland plants is warranted to assess effects of elevated $CO_2$ on wetland carbon cycle accurately.

The purpose of this study was to describe mother -infant interacting behavior patterns related to newborn infant feeding and to explore the mother's cultural belief about their infant. The data collection was conducted by observation and interview. Twenty-five mothers and their newborn infants who were normally delivered and were also planned to breast feed were comprised as the subjects of this study. All subjects were interviewed and observed individuaily at 1 to 5 days after the delivery at the hospital, mid -wife's clinic, Maternal Child Health Center and their home throughout the country from remote area to big city, The observation data were recorded with symbolic letter on a recording sheet newly developed as a result of preliminary study. The interview data were taperecorded and then recorded in narrative form. Mother - infant interaction behaviors in early feeding period were analyzed based on 19 analytic sub-categories and their composing elements. Unit of analysis were mother, infant and mother -infant dyad. 8 analytic categories draw from the data. Each were preparation, instrument, interaction inducing, evaluation referred to mother's behavior, preparation, instrument, interaction inducing referred to infant's behavior and synchronic behaviors referred to mother - infant dyad. Frequencies of behavior items based on the categories were converted to percent. The result showed that in mother's preparation behavior, the breast condition of Korean mother can be an affecting factor for mother - infant interaction during feeding, and vocalization behavior was observed most frequently in interaction inducing behavior while the least frequent behavior observed was contacting. Subcultural characteristics of mother - infant interaction behaviors were analyzed for their relationships between groups of mothers who have lived in remote area vs urban area, and who were multipara vs primipara. Using a chi -square test, there were statistically significant relationships in the activity of psychological readiness in preparation behavior and the movement of extremities for the position of instrumental behavior in both groups. However, interaction inducing behaviors were not related with statistical significance in any set of groups. Accomplishment of marriage, bonding and emotional mediation of family members were the categories related to mother's cultural belief about the infant in aspect of functional values. Infant at birth is considered little more than a biological organism without social capabilities. Although the newborn infant is still be attached to his mother, he makes his mother extend her territoriality. The mother's interacting behavior toward her infant based on those beliefs appeared task oriented, separative behavioral series. On the other hand, it was seen that infant reacted independently to his mother's behavior by the in-nate perceptual abilities. Those independent behavioral series of mother and infant on the feeding situation were synchronized at any moment. Nurses are In a unique position to teach mothers about their infant's capabilities and help reducing some of uncertainty about infant's behaviors. Study results indicated that the informations infant's social capabilities and breast feeding should be given to the mothers. The results of this study have several implications for nursing. First, the study results will be used as fundamental resources for the development of the assessment tool about the early mother - infant interaction. Second, the results could be a relevant information in the fied. I of maternal child nursing education as real and useful data. Third, the behavioral patterns of early mother - infant interaction which were classified based on the qualitative analysis could be used for nursing theory development as very fundamental data.

Purpose: The purpose of this study is to identified patterns and trend of studies and to analyzed the nursing research related to the mother-child interaction in Korea and to improve direction of nursing research in mother-child interaction in Korea. Method: The research studies related to the mother-child interaction were selected from the Korean Nurses Academic Society Journal, and from dissertation, which were conducted between 1961 and 2002 with the consideration of the condition and the cultural specialty of Korea. The total numbers of the studies were 34. These studies were classified according to 1)time of publication or presentation, 2)research design, 3)type of interaction objects, 4)measurement tool, and 5)chief content of studies. Ressult: 1) Until 1984, there was no research studies related to mother-child interaction. The number of studies on the mother-child interaction on the mother-child interaction has been increased rapidly after 1985. The mother-child interaction studies were 13(38.2％) from the doctoral dissertation, 4(11.8％) from the Master's theses and 17(50％) other papers were published in academic journals. 2) Experimental studies of research design was used in these research studies was 13(38.2％). Descriptive studies was 8(23.6％), correlational studies was 4(11.8％) and comparative studies was 4(11.8％). Qualitative study was just one(2.9％) and literature review was 4(11.8％). Especially experimental studies has been increased. 3) Participants of these studies were mother and infant 29(85.5％), father and infant 2(5.9％), mother and fetus 2(5.9％) and nurse and infant 1(2.9％) 4) Utilization of instruments as follows: 13 studies used Walker et al(1986)'s MIPIS (Mother-Infant Play Interaction Scale), 6 studies used Barnard(1978)'s NCAFS (Nursing Child Assessment Feeding Scale), 4 studies used NCATS(Nursing child Assessment Teaching Scale) for assessing mother-infant interaction. 3 studies used Stainton(1981)'s Parent-Infant Interaction Scale. Choi(1987), Kim(1999) and Kim and Son(1997) used measurement tool researcher made which was modified from NCATS (Nursing child Assessment Teaching Scale) and AMIS(Assessment of Mother-Infant Sensitivity Scale). Other tools used to survey influencing factors of interaction. 5) Content of the research studies were classified 3 different types, such as ① studies about the mother-child interactions' pattern, ② studies about influencing factors of the mother-child interaction, ③ studies about effect of nursing intervention program to improve the mother-child interaction. Conclusion: Therefore we make following suggestions which are made based on the above research analysis : 1) In the future research studies need to compare with other area of discipline in mother-child interaction. 2) More attention and in depth research is needed to validate in terms of research design and statistical data analysis. 3) It is important to develop the instruments which is culturally acceptable in Korea society. 4) The results of correlational studies and experimental studies needs to the integrated by meta analysis.
