Infanthood is a crucial period when mental and emotional developments take place along with physical growth. Adequate supply of nutrition is essential during this period and there is an urgent need for proper education and guidance on balanced nutrition. Therefore, this study tried to set the direction for developing baby food by investigating the conditions of weaning status and mothers perspectives on weaning. According to the result of this study, the average period when interviewees began weaning of their infants is 4.1 months and finishing period of weaning is 14.2 months on average. The frequency of consuming commercial weaning food is once a week. As high as 88.4% and the fruit juice was mainly used as the starting weaning food. The consumtion rate, more than once a day, is as high as 60%, they use commercial weaning food for convenience, especially when they are out. The 65% of surveyed group show rather dissatisfactory view about the commercial weaning food, and wanted improvements and changes. Interviewees wanted to obtain the information on baby food sold in the market and how to prepare baby food through technical literatures, and they frequently relied on commercial baby food due to its convenience. The most desired type of baby food was semi-solid paste in a disposable package that can be stored at room temperature.

Background: Though antenatal magnesium sulfate (MgSO4) is widely used for fetal neuroprotection, suspicions about the long-term neuroprotection of antenatal MgSO4 have been raised. Methods: We investigated short- and long-term outcomes of antenatal MgSO4 use for 468 infants weighing < 1,500 g with a gestational age of 24–31 weeks. Results: Short-term morbidities and the risk of developmental delay, hearing loss, and cerebral palsy at a corrected age of 18–24 months and 3 years of age did not decrease in the MgSO4 group (infants who were exposed to MgSO4 for any purpose) or neuroprotection group (infants who were exposed to MgSO4 for fetal neuroprotection) compared with the control group (infants who were not exposed to MgSO4). The z-scores of weight, height, and head circumference did not increase in the MgSO4 group or neuroprotection group compared with the control group. Conclusion: Antenatal MgSO4 including MgSO4 for neuroprotection did not have beneficial effects on long-term neurodevelopmental and growth outcomes.

<P>Pesticidal activities of 4-[5-(2-cyclopropylaminopyrimidin-4-yl)-4-(4-chloro-2-fluoro-phenyl)thiazol-2-yl]-1-methylpiperidine, designated as Comp I, have been determined against a mosquito larva,<I>Culex pipiens pallens</I>, and a phytopathogenic fungus,<I>Phytophthora capsici</I>. Comp I was used as the leading compound in this study. The compounds were synthesized by reacting them with two functional groups, 3-thiophenyl and 2-thiophenyl groups, instead of 4-chloro-2-fluorophenyl group in Comp I. Other functional groups such as 2-aminothiazole, 2-(1-methylpiperazin-4-yl)thiazole, and 2-(piperazin-4-yl)thiazole were also introduced instead of 2-methylpiperidin-4-yl-thiazole of Comp I. Compounds designated as XIII-6~XV-7 were newly synthesized and their structures were confirmed by<SUP>1</SUP>H- and<SUP>13</SUP>C-NMR spectroscopy. Mosquito larvicidal activities of all the synthesized compounds against<I>C. pipiens pallens</I>were examined and Comp I among them showed the strongest larvicidal activity as 0.513 mM of LC50value. The fungicidal activities of all the synthesized compounds against<I>P. capsici</I>were examined using the whole plant method. Among the XIII-6~XV-7 chemicals, 5-(2-cyclopropylaminopyrimidin-4-yl)-4-(thiophen-2-yl)thiazol-2-amine (VIII-6) showed the most potent antifungal activity<I>in vivo</I>. While the EC50value of the commercial fungicide dimethomorph was 4.26 <I>μ</I>M, EC50of VIII-6 was 0.94 <I>μ</I>M. Therefore, thiazole derivatives can be considered as viable candidates for the control of mosquito larvae and plant diseases.</P>

<P>Atherosclerosis is a chronic progressive inflammatory disorder and the leading cause of cardiovascular mortality. Here we assessed the dynamic changes of T-cell-derived cytokines, such as inteferon (IFN)-γ, interleukin (IL)-17 and IL-4, during the progression of atherosclerosis in apolipoprotein E-null (ApoE<SUP>−/−</SUP>) mice, to understand the role of immune responses in different stages of atherosclerosis. Male ApoE<SUP>−/−</SUP> mice were fed a high-fat, western-type diet (WD: 21% lipid, 1.5% cholesterol) after 5 weeks of age and were compared with C57BL/6 wild-type control mice fed a standard chow diet. Atherosclerotic lesions appeared in the aortic sinus of ApoE<SUP>−/−</SUP> mice 4 weeks after WD and the lesions progressed and occupied >50% of the total sinus area 16 weeks after WD. Aortic IL-17 mRNA and protein expression started to increase in ApoE<SUP>−/−</SUP> mice after 4 weeks on the WD and peaked at around 8–12 weeks on the WD. In terms of systemic expression of T-cell-derived cytokines, IL-17 production from splenocytes after anti-CD3/CD28 stimuli increased from 4 weeks on the WD, peaked at 12 weeks and returned to control levels at 16 weeks. The production of IFN-γ and IL-4 (Th1 and Th2 cytokines, respectively) from splenocytes was delayed compared with IL-17. Taken together, the present data indicate that Th17 cell response may be involved at an early stage in the development of atherosclerosis.</P>

Infanthood is a crucial period when mental and emotional developments take place along with physical growth. Adequate supply of nutrition is essential during this period and there is an urgent need for proper education and guidance on balanced nutrition. Therefore, this study was designed to assess to current status of lactation and to investigate mothers' perspectives on human milk and formular milk. As random samples for this study, a total of 352 mothers having infant under the age of 4 were surveyed. 27.3% of mother surveyed were breast-feeding, 38.0% were formula-feeding and 34.7% were mixed-feeding. According to the result of this study, the percentage of breast feeding was on the decrease, while the dependence on formular milk was on the rise. The main reason of formula-feeding was insufficient secretion of human milk on mothers part. The major factors that affect to select feeding method were employment status, degree of education, family income and age. Also, the interviewees desired the product fortified with special ingredients that are not contained in formular milk currently available in the market. The most concerned problem of formula milk was indigestion and the interviewees wanted the formular milk to be improved digestibility.

The purpose of this study is to investigate the moderating effect of mother’s discipline style on the relationship between young children’s difficult temperament and young children’s peer interaction. To verify this, 307 mothers with 36-72 months of young children were asked to measure their difficult temperament, peer interaction, and mother’s discipline. The results of this study are summarized as follows. First, young children’s difficult temperament showed a significant negative correlation with young children’s peer interaction, the mother’s positive discipline showed a significant positive correlation with young children’s peer interaction, and the mother’s negative discipline showed a significant negative correlation with young children’s peer interaction. Second, young children’s difficult temperament was found to affect young children’s peer interaction. Third, mother’s positive and negative discipline had an effect on young children’s peer interaction. Fourth, the moderating effect of mother’s positive discipline style was proved in the relationship between young children’s difficult temperament and young children’s peer interaction. Fifth, the moderating effect of mother’s negative discipline style was proved in the relationship between young children’s difficult temperament and young children’s peer interaction. Based on these, the implications and limitations of this study and the direction of follow-up research were discussed.

The purpose of this paper is to investigate Cheonan citizens’ demands, inconveniences and behavioral characteristics by analyzing the civil complaints. To do so, we apply social network analysis to keywords extracted from 12,345 civil complaints from `Allso 365’, the Cheonan city e-bulletin board. We seek improvements for rapid processing of the complaints, and furthermore policy implications to satisfy civil petitioners. This study is done by identifying Cheonan citizens’ need and administrative/policy requirements. As a result, this paper suggests diversification of categories in the e-bulletin board and extra care on traffic problem.
