Purpose: Thickened infant formulas reduce regurgitation frequency and volume. Because the digestive tolerance of locust bean gum-containing formulas is controversial, the effectiveness and tolerance of a locust bean gum-thickened formula in infants presenting with regurgitation was evaluated. No other interventions were allowed during the 1 month follow-up period. Methods: We conducted an open, prospective, observational study of a locust bean gum-thickened formula administered to infants presenting with moderate to severe regurgitation according to parents during 1 month. Effectiveness and tolerance were assessed by evaluating gastrointestinal symptoms and quality of life indicators. Results: A total of 2,604 infants with an average age of 9.3±4.3 weeks were included in this 1 month trial. Regurgitation frequency and estimated volume decreased significantly (p<0.001) and the episodes were resolved completely in 48% of the infants. A significant decrease in duration of crying and episodes of gas (p<0.001), with improvement in quality of life parameters, was observed. Stool frequency increased and stool consistency softened (p<0.001) to levels within the physiologic range, consistent with the increased fiber load (0.42 g/100 mL). Conclusion: Locust bean gum-thickened formula decreased infant regurgitation, was well tolerated, and improved parental quality of life. Stool composition and frequency of the infants remained within the physiologic range.

Winter cereals are acclimated during wintering, and thereafter their freezing resistance is increased. In order to analyze inheritance and heritabilities for photoinhibition of photosynthesis by high light intensity under low temperature, and to evaluate the relationship between low temperature-induced photoinhibition and winter survival, 4 parental half diallel crosses were used. The detached leaves of 7-8cm long from plants grown for 35 and 55 days were placed on wet filter paper and placed in trays at 5$^{\circ}C$ cold room with 1,200 $\mu$mol $m^{-2}$ $s^{-1}$ PPFD. Chlorophyll fluorescence was measured with a chlorophyll fluorescence system after dark adaptation for 30 min. The Fv/Fm of 35day old plants was reduced from 0.714 in the control leaves to 0.409 and 0.368 following photoinhibitory treatment of 6h and 8h and the CVs were increased from 0.8% to 22.2-22.3%. The Fv/Fm of 55-day old plants was reduced from 0.775 in the control leaves to 0.485 and 0.439 following photoinhibitory treatment of 10h and 12h, respectively. According to half diallel cross analysis, Reno and Dongbori 1 (highly resistant to photoinhibition) was dominant, but Oweolbori (susceptible to photoinhibition) was recessive, and photoinhibition showed partial dominance with highly additive gene action. Dongbori 1 showed the greatest GCA effects for photoinhibition, and GCA/SCA ratios (8.7-22.3 times) indicated that the additive variance for the character was more important. Winter survival in barley crosses was positively correlated with resistance to photoinhibition and significantly fitted by linear regression ($R^2$=0.751$^{**}$-0.779$^{**}$). The chlorophyll fluorescence measured by Fv/Fm has been found to be highly inheritable and very useful in evaluating relative levels of freezing resistance in barley.ley.

We surveyed 837 students attending elementary schoolchildren in Korea for health functional foods (HFF) consumption and significant variables for their HFF consumption including demographic characteristics, parental health concern on offsprings, food eating frequency of subjects and beliefs on potential efficacy of HFF by subjects. The consumption prevalence of HFF was 45.9%, and among all types of HFF, nutritional supplements were taken most frequently, followed by apricot extract-fermented products > lactic acid bacteria containing products > EPA/DHA containing products > red ginseng products. HFF consumption was higher in subjects had parents of high education level (p < .05) and those from families with a high socioeconomic status (p < .01) in comparison to each corresponding group. Health concern on offsprings by parents (p < .001) and consumption ratio of HFF by family (p < .001) was higher in consumers than in nonconsumers of HFF. Total score of dietary assessment was higher in consumers than in nonconsumers of HFF (p < .01), and consumers had a more positive view concerning the potential efficacy of HFF than did nonconsumers (p < .001). Most consumers of HFF took HFF when they were healthy (42.5%), and they did not feel special effects through HFF consumption (47.7%). Most consumers of HFF got the information on HFF from family and relatives (24.8%), and most of them purchased HFF at pharmacy or oriental medicine clinics (53.9%). HFF consumers preferred multi-vitamins and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread consumption of HFF by elementary schoolchildren, the reasonable consumption of these products for the contribution to their overall health and well-being should be emphasized through nutrition education for them and their family.

The purpose of the present study was to examine the causal effects of the family health of baby boomer parents as a determinant of marital preparation skills of eco-boomer children. Subjects in this study consisted of 475 students born before 1992, and whose parents were born from 1955 to 1963. The programs of SPSSWIN 18.0 and LISREL 8.51 were used for data analysis. The result of this study showed that the financial management skills of saving and consumption were the lowest of marital preparation skills of echo-boomer generation. Besides, baby boomer parents' family health perceived by their children was found to be the determinant of the marital preparation skills of eco-boomers. Particularly, the effect of family health was shown to be high on parental role skill, conflict resolution skill, and parenting preparation skill of marital preparation skills, whereas it was revealed to be relatively low on financial management skill. Findings of this study can be used in developing educational programs of marital preparation skills for eco-boomers.

Recent intervention studies document that mother-child dyads with higher levels of Emotional Availability (EA) report fewer child behavior problems than dyads with lower EA. This study examines possible mechanisms that lead to this result by looking at the parent-child micro-system as a whole, with multi-dimensional relationships that include individual differences in the child's cognitive level, parental stress and parent-child interaction. A total 67 children ($1{\frac{1}{2}}$ to $5\;{\frac{1}{2}}$ years of age) and their mothers were videotaped during 30-min play interactions. Interactions were coded using the Emotional Availability (EA) Scales (Biringen, Robinson, & Emde, 1998). Mothers completed Parenting Stress Index-Short Form, Child Behavior Checklist/$1\;{\frac{1}{2}}$ - 5, and the Ages Stages Questionnaire. The findings showed that mothers with higher levels of parenting stress were more likely to be intrusive, hostile, insensitive, and had a tendency to do less structuring in play. The children of stressed and depressed mothers demonstrated less involvement and responsiveness towards their mothers. Children who have higher dyadic EA scores experienced fewer externalizing and internalizing problems. SEM analyses results showed a mediation effect of EA on the association between maternal psychological well-being and child behavior problems. Fewer deficits in child communication skills and problem solving skills that were related with lower parenting stress and depression were associated with higher maternal non-intrusiveness. Higher non-intrusiveness was related to less internalizing and externalizing problems that indicated the indirect effect of child cognitive competence. Possible interpretations and implications of the study findings are discussed.

The purpose of this paper is to analyze how social supports, such as family, teachers, and friends, affect the school adjustment of children who were abused by their parents, and suggest the interventional solutions in order to improve the social support system and school adjustment. 692 children, aged 4 to 6 in primary schools in Busan, were chosen for the survey and all of them are currently under children's service. Among the respondents, 485 children (70.1%) have experienced abuse, and neglect was the most frequent abuse experienced among them. Neglected children were influenced by teachers, families and friends' support in terms of social support for school adjustments. However, the emotionally abused children were influenced by families, teachers and friends in terms of social support for school adjustments. In addition, children who experienced physical abuse have been influenced by families and teachers'support. Support from friends has no meaning for them. As a result, this paper suggests that an effective interventional solution will be necessary for the school adjustment of abused children. The effective interventional solutions are firstly that neglected children require a high level of attention from their teachers and teachers should encourage parents with parental education and counseling to be helpful for their children. Secondly, emotionally abused children require strong family support through parents'education for child development and caring support programs. Finally, physically abused children need caring programs which develop supportive relationship skills both with parents and teachers for their adjustment in school.

The purpose of this study was to analyze the effects of elementary school students' interpersonal stress and attitudes toward help on happiness. The subjects were 171 elementary school students. Data were analyzed using ANOVA, Pearson's correlation analysis, and hierarchical regression analysis. The results of the study are as follows. First, there was a significant negative correlation between interpersonal stress and happiness. Attitudes toward help had a significant positive correlation with happiness. Second, parents and peer relationship stress had significant negative influence on happiness. Third, help seeking attitude toward parents and teacher among the sub-factors of help seeking attitude had a significant positive influence on happiness. Fourth, the relationship between parental stress and happiness showed a significant mediating effect on parents and teacher attitude toward help. The relationship between teacher stress and happiness showed a significant mediating effect on teacher attitude toward help. The relationship between peer relationship stress and happiness had no mediating effect of attitude toward help. Based on these results, we discussed the importance of attitude toward help in the relationship between stress and elementary school students' happiness.

Recently, we isolated the mutant Kluyveromyces marxianus 36907-FMEL1, which demonstrated improved xylose reductase activity as compared to the parental strain, K. marxianus ATCC 36907. Effects of agitation conditions on xylitol production were verified using a bioreactor system. Under an agitation speed of 400 rpm, K. marxianus 36907-FMEL1 exhibited the highest xylitol yield (0.57 g/g) and productivity ($0.64g{\cdot}l^{-1}{\cdot}h^{-1}$) at $30^{\circ}C$. When the fermentation temperature was increased to $40^{\circ}C$, interestingly, xylitol yield and productivity were found to be increased to 21% (0.64 g/g) and 58% ($0.90g{\cdot}l^{-1}{\cdot}h^{-1}$), respectively, under the optimized agitation conditions.

Cordyceps militaris, a member of Ascomycota, a mushroom referred to as caterpillar Dong-chung-ha-cho, is commercially valuable because of its high content of bioactive substances, including cordycepin, and its potential for artificial cultivation. Cordycepin (3'-deoxyadenosine) is highly associated with the pharmacological effects of C. militaris. C. militaris is heterothallic in that two mating-type loci, idiomorph MAT1-1 and MAT1-2, exist discretely in two different spores. In this study, nine C. militaris strains were mated with each other to prepare newly bred strains that produced a larger amount of cordycepin than the parent strains. Nine strains of C. militaris were identified by comparing the internal transcribed spacer sequence, and a total of 12 single spores were isolated from the nine strains of C. militaris. After the MAT idiomorph was confirmed by PCR, 36 mating combinations were performed with six single spores with MAT1-1 and the others with MAT1-2. Eight mating combinations were successfully mated, producing stroma with perithecia. Cordycepin content analysis of all strains by high-performance liquid chromatography revealed that the KASP4-bred strain produced the maximum cordycepin among all strains, regardless of the medium and stroma parts. Finally, universal rice primer-PCR was performed to demonstrate that the bred strains were genetically different from the parental strains and new C. militaris strains. These results may be related to the recombination of genes during mating. The newly produced strains can be used to meet the industrial demand for cordycepin. In addition, breeding through mating suggests the possibility of producing numerous cordycepin-producing C. militaris strains.
