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.

The purpose of this study was to analyze laboratory instructions used in elementary school science lessons by utilizing an analysis instrument for science laboratory instruction(AISLI). This analysis instrument was comprised of 3 elements; the aim of the laboratory activity, the interaction generated, and the inquiry process. There were also a total of 20 sub-categories and its validity was identified at 0.89 by four science educators. For the purposes of this study, 90 laboratory instructions were video-recorded, then transcribed. Laboratory instructions were analyzed by three analyst teams, and the inter-rater reliability within teams was checked through Pearson correlation, with a score of 0.91. The results of this study were as follows: the two principle aims of laboratory activity, namely, to acquire declarative knowledge and to increase attitudes toward science, were observed to be in evidence in 98.9% and 92.2% in laboratory instructions, and the levels of categories of the interaction and inquiry processes were situated at level-1. The implications of these results are that laboratory instructions currently in use do not place sufficient demands upon students' scientific thinking and are not at all conducive to student-centered activities. Therefore in order to remedy this situation, the usefulness of current science laboratory instructions need to be re-evaluated.

In this study, we tried to understand preschooler clothing trends and identify the purchase behaviors of various consumers, such as grandparents, aunts, uncles, and parents, who are the main consumers of the preschooler clothing market. We conducted in-depth interviews with consumers who were interested in preschooler clothing, purchased it frequently, and bought preschooler clothing within the last three months. Their purchase motivations and purchase behaviors were analyzed through exploratory and inductive analysis. The analysis was conducted by integrating categories into one process centered on core categories through open coding, axial coding, and selective coding. The results of this study included that 1) a variety of clothing purchase behaviors appeared as a central phenomenon, 2) the causal conditions that contributed to this phenomenon were the buyers' childcare experiences, purchase experiences, the personal consumption values of individuals, and income levels, 3) in response to the central phenomenon, the parents' action/interaction strategies were acceptance and rejection of purchased clothing, 4) contextual and Intervening conditions affecting action/interaction strategy were family environment changes, the VIB (Very Important Baby) phenomenon, parents' clothing involvement, and the relationship with the buyers, and acceptance by the users, and 5) as a result of the strategy expressed as acceptance and rejection, various clothing behaviors emerged. In this study, we identified that there are various influencers, apart from parents, involved in children's clothing consumption. Therefore, we need to keep in mind that various purchase behaviors and clothing trends that appear during one's childhood may affect the individual's clothing behavior in the future.

The leading cause of cancer mortality globally amongst the women is due to human papillomavirus (HPV) infection. There is need to explore anti-cancerous drugs against this life-threatening infection. Traditionally, different natural compounds such as withaferin A, artemisinin, ursolic acid, ferulic acid, (-)-epigallocatechin-3-gallate, berberin, resveratrol, jaceosidin, curcumin, gingerol, indol-3-carbinol, and silymarin have been used as hopeful source of cancer treatment. These natural inhibitors have been shown to block HPV infection by different researchers. In the present study, we explored these natural compounds against E6 oncoprotein of high risk HPV18, which is known to inactivate tumor suppressor p53 protein. E6, a high throughput protein model of HPV18, was predicted to anticipate the interaction mechanism of E6 oncoprotein with these natural inhibitors using structure-based drug designing approach. Docking analysis showed the interaction of these natural inhibitors with p53 binding site of E6 protein residues 108-117 (CQKPLNPAEK) and help reinstatement of normal p53 functioning. Further, docking analysis besides helping in silico validations of natural compounds also helped elucidating the molecular mechanism of inhibition of HPV oncoproteins.
