The objectives of this study were to investigate the effect of perceiver's fashion involvement, clothing color, and background of object person on image perceptions of clothing, and to examine how clothing color preference vary according to perceiver's fashion involvement. Subjects were 273 college women in the metropolitan area of Seoul. The T-shirt was changed into 11 colors by using the CAD system. Five factors were derived to account for the dimensions of image perception. These were individuality, elegance, femininity, activity, and neatness. Perceiver's fashion involvement gave a significant influence on perception of individuality. Clothing color gave significant influences on 5 image dimensions. White and beige were evaluated neat image. Neatness factor had an interaction effect by fashion involvement and clothing color. The high involvement group evaluated white and beige shirt more neatly, and orange and yellow less neatly than the low involvement group. Individuality and elegance had an interaction effect by fashion involvement and background of object person. The high involvement group liked red, violet, and black shirt more than the low involvement. Refined and becomingness image gave significant influences on clothing color preference in both high and low involvement groups.

This study investigated the effects of cod liver oil and chromium picolinate on the serum traits and egg yolk fatty acids and cholesterol content in laying hens. One hundred 45-week old single comb white Leghorn laying hens were assigned randomly to four groups. These groups were: (1) control (soybean oil), (2) 1,000 ppb (${\mu}g/kg$) chromium (organic form chromium picolinate) (Crpic), (3) 3% cod liver oil (CLO), and (4) 1,000 ppb chromium with 3% cod liver oil (CLO+Crpic). The experiment was conducted for 40 days. Results indicated that serum triacylglycerol (TG) and cholesterol contents in the CLO group and the serum glucose content in the Crpic group were significantly lower than those in the control group (p<0.05-0.01). The yolk cholesterol content in the CLO and Crpic groups were also lower than the control group (p<0.01). The lipoprotein profile displayed that in the Crpic group, high-density lipoprotein (HDL) and HDL-cholesterol (HDL-C) were significantly higher (P<0.05) than the control group. Meanwhile, low-density lipoprotein+very low-density lipoprotein (LDL+VLDL) and LDL-C+VLDL-C were significantly lower (p<0.05) than the control group. Notably, of all four groups, the CLO group displayed a more profound effect on serum traits and lipoprotein (p<0.05-0.001). Furthermore, the fatty acid composition of the egg yolks presented that C18:2 in the CLO and Crpic groups was significantly lower (p<0.05-0.001) compare to the control. However, only in the CLO group, C18:3, C20:5 and C22:6 were significantly higher (p<0.001) than the control. Only serum glucose and LDL+VLDL showed the CLO${\times}$Crpic interaction (p<0.05), most parameters did not. Therefore, supplemented chromium picolinate or cod liver oil in the diet of laying hens had beneficial effects. However, when these two factors were combined, there was no interaction with most parameters.

Background: Valproic acid is widely used in the treatment of generalized tonic-clonic and partial seizures. The carbapenem class is the most potent and widest spectrum of antimicrobial activity. Concomitant administration of carbapenems and valproic acid has been reported to decrease the serum concentration of valproic acid, which is sometimes associated with seizures. The purpose of this study is to evaluate the changes in valproic acid concentration and half life and the frequency of seizure during concomitant administration of valproic acid and carbapenems. Method: This study was performed retrospectively on total 40 cases with identified valproic acid concentration during concomitant administration of valproic acid and carbapenems at Kangbuk Samsung Hospital from February 1st, 2006 to October 31st, 2011. Patients were classified into 3 groups: ertapenem group (n=14), imipenem group (n=12), meropenem group (n=14). Results: The mean serum concentrations in each group during combined treatment were $9.50{\pm}8.84$, $21.88{\pm}8.17$ and $10.62{\pm}8.67$ mg/L, respectively (p < 0.001). The mean half-lives in each group during concurrent use of valproic acid and carbapenems were $3.18{\pm}0.81$, $4.63{\pm}1.97$ and $2.67{\pm}1.69$ hr, respectively (p < 0.001). The valproic acid serum concentration decreased by 75.5%, 54.1% and 84.1% and the half-life of valporoic acid decreased by 65.6%, 35.7% and 73.5%, respectively. Total cases with seizure were 12(30%) with 5(35.7%) in the ertapenem group, 3 (25.0%) in the imipenem group and 4(28.6%) in the meropenem group (p=0.911). There were no specific factors to influence on seizure development during combined treatment. Conclusion: Concurrent use of carbapenems and valproic acid should be avoided. If concomitant administration is essential, very close serum concentration monitoring and clinical observation are necessary.

The purposes of this study were to a develop a preventive tailored early intervention program and to investigate the effects of the program on the quality of parenting for low income families. The subjects were eighty five infants, aged 13 to 32 months, and their mothers. Of the 85 mother-infant dyads, 42 dyads were randomly assigned to the experimental group and 43 dyads to the control group. To prevent the risks of the adverse development of infants from low income families a tailored intervention program was created based upon the transactional model. This emphasized the quality of the home environment and of the daily mother-infant interaction. The risk factors were assessed and progress monitoring was undertaken for the preventive tailored intervention treatment. In order to assess the effects of the program, HOME, the NCAST Teaching Scale and the Parenting Stress Index/Short From were used. The collected data were analyzed with descriptive statistics, ANCOVA, and the McNemar test. The experimental group showed a significant increase in performance and higher scores than the control group on the scores from HOME, and the NCAST Teaching Scale and significant decrease and lower scores in the Parenting Stress Index(SF).

Purpose: The study was done to investigate behavioral problems in toddlers who were born prematurely and to analyze related factors. Methods: A cross-sectional explorative study was conducted with 72 preterm birth (PTB) children at 24 to 41 months of corrected age who were born at 28 to 37 weeks' gestation. During home visits, behavior problems were assessed using the Behavior Rating Index for Children (BRIC). Using a BRIC score of ${\geq}30$, children with suspected behavior problems were grouped in the non-regular behavior group. Results: Of the children, 38.9% belong to the non-regular behavior group. The mental development index score for the Korean-Bayley Scale of Infant Development- II was higher for the non-regular behavior group compared to the regular behavior group (t=2.26, p=.027). Logistic regression analysis showed that lower maternal attachment (<96, OR=3.4, 95% CI[1.1, 10.4]) and higher parenting stress (${\geq}97$, OR=4.8, 95% CI[1.3, 17.3]) were independently related to non-regular behavior. Conclusion: PTB Toddlers are at risk for behavior problems which are associated with low cognitive performance. Maternal-child attachment and maternal parenting stress were strongly related to behavior problems in these children. More attention is needed to understand possible behavior problems in young children with PTB, particularly focusing on maternal-child interaction and maternal mental well-being.
