The increasing use of cardioplegic solution for the reduction of ischemic tissue injury requires that all cardioplegic solution be carefully assessed for any protective or damaging properties. This study describes functional assessment of the efficiency of steroid in cardioplegic solution by using a Langendorffs perfusion model. Isolated rat heart were subject to a 2 minute period of coronary infusion with the steroid mixed cold cardioplegic solution immediately before and also at the midpoint of a 60 minutes period of hypothermic [10\ulcorner\ulcorner] ischemic arrest. The result of this study were as follows: 1.Spontaneous heart beat after ischemic arrest occurred 14 second later Langendorffs reperfusion in the steroid mixed Young & GIK group and 16 second later in the control group. [Young & GIK without steroid] A good recovery state of spontaneous heart beat was shown in both groups. 2.The percentage of recoveries of heart rate during the 30 minute after postischemic Langendorffs reperfusion was; at first 5 minute 106.3\ulcorner.7% [P<0.05] in the steroid mixed Young & GIK group. This percentage of recovery of steroid mixed Young & GIK group was significantly greater than the control group during the first 5 minute course. 3.The percentage of recovery of coronary flow during the 30 minute after postischemic Langendorffs reperfusion was; at first 5 minute 101\ulcorner.2% in the steroid mixed Young & GI K group. This percentage of recovery of the steroid mixed Young & GIK group was not significantly than the control group during the first 5 minute.

An experiment was conducted to study the comparative performance of cattle fed young or mature guinea grass (Panicum maximum Jacq. ecotype A) and urea supplemented rice straw. Evaluation was based on intake and digestibility parameters. Twelve crossbred bulls calves weighing $90{\pm}15$ kg were offered young (4 weeks regrowth) or mature (9 weeks regrowth) grass in the long or chopped (10-15 cm) form, and rice straw supplemented with urea. The diets were offered 30-60% in excess of voluntary intake, and the experiment consisted of two periods. The crude protein content of the young grass, mature grass and the straw offered were 12.2, 5.4 and 7.7%, respectively, and the refusal was 10.1, 3.9 and 7.0%, respectively. The organic matter digestibility of the young grass (69%) was significantly higher than the mature grass (62.5%) and straw (55.8%) diets. The organic matter intake (kg/100 kg LW/day) of the unchopped and chopped grass diets were 2.6 and 3.3 respectively, and these values were significantly higher (p < 0.01) than the young grass (2.3) and straw (2.1) diets. The digestible organic matter intake (DOMI) of the mature grass diet offered in the chopped form (2.1 kg/100 kg LW/day) was significantly higher (p < 0.01) than the other three diets. The DOMI of the young and mature grass offered in the long form was similar (1.6 kg/100 kg LW/day), but were significantly better (p < 0.01) than the urea supplemented straw diet.

The purpose of this research was to explore the influence of a mother's motivational beliefs in the context of the child education and parent-teacher relationship and the impact that it has on the learning related skills of young children. The participants in this study consisted of 243 mothers of 4~5 years old children and 20 teachers in 5 child education centers located in Seoul, Korea. The data was analyzed by means of using statistical method such as mean, standard deviation, t-test, Pearson correlation, and stepwise regression. The major findings of this study were as follows: First, there were significant differences between parent-teacher relationship and learning related skills of young children according to the children's sex and maternal educational level. Second, children's sex, maternal educational level, and the parent-teacher relationship were significantly related with the learning related skills of young children. Last, mother's motivational beliefs in the context of child education and the parent-teacher relationship directly influenced the learning related skills of young children. The results of this study suggest that positive parent-teacher relationships are important for developing the learning related skills of young children and this in turn can predict the level of children's adjustment and success in school.

The immune system may play an important role in aging and the changes in the immune status are associated with treatment of various immunomodulators. This study examined the effects of $\beta$-glucans isolated from mushroom fungi, Coriolus versicolor on macrophages functions in young (8-weeks-old) and aged (82-weeks-old) male C57BL/6 mice. When peritoneal macrophages were treated with various concentrations of $\beta$-glucan ($1-100\;{\mu}g/ml$) for 24 hrs, tumoricidal activity, NO production and phagocytic activity were significantly increased in the young mice, whereas there are no effects in the aged mice. These results suggest that $\beta$-glucans has differential effects on the macrophage functions in young and aged mice and age nutrition might need to be considered to select proper immunomodulator. In addition, $\beta$-glucan could be used clinically for the treatment of diseases such as cancer therapy in the young.

This study was designed to analyze the effects of methanol extracts and solvent fractions of the young branch of Prunus persica on scavenging activity of ROS, RNS and inhibiting activity of oxidative modification in human LDL induced by copper ion or free radical generator. The scavenging capacities of the fractions on DPPH radical, superoxide radical, nitric oxide and peroxynitrite were exhibited the highest in ethylacetate fraction, followed by butanol fraction. In the copper-induced LDL oxidative modification system, the highest antioxidant activity was revealed in ethylacetate fraction, and butanol fraction exhibited a similar activity. However, solvent fractions of the young branch of Prunus persica showed a relatively low antioxidant activity in the AAPH-mediated LDL oxidation. In addition, ethylacetate and butanol fractions also inhibited the copper-mediated LDL oxidation in the REM assay, which was comparable to that of the positive controls, including EDTA, ascorbic acid and BHT. Futhermore, a content of total phenolics in these two fractions was higher than that of the other fractions. These results indicated that ethylacetate and butanol fractions of the young branch of Prunus persica were useful for the prevention of the free radical- or metal ion-induced oxidative damages.

The purpose of this study is to examine the differences of use behavior and environmental perception of a park and to analyze the influence of environmental perception factors on park satisfaction among 7 parks in Suseong-gu, Daegu. The data from the 255 questionnaires of young adults (30-59) and old adults (more than 60) who use the park more than once a week were used for the analysis. In terms of park use behavior, young adults used the park for walking and jogging mainly on weekday evenings, while old adults used the park for walking and rest mainly during weekday daytimes. In addition, old adults used the park more times a week than young adults, and spent more time in the park. In the analysis of the environmental perception of the park, similar results were found in both age groups but overall, old adults were more satisfied with the park environment than the young adults. As a result of analyzing the influence of environmental perception factors, it was determined that park satisfaction in young adults has a significant influence on 'use amenity', 'use convenience', 'facility suitability', and 'landscape diversity' in this order. On the other hand, park satisfaction for old adults has an influence on 'use amenity', 'facility suitability', and 'use convenience' in this order. The findings of this study can be used as an effective basic data for future park planning considering age groups.

The purpose of this study is to examine the factors that affect the social competence of young children and to promote the social competence development of the age group. The study gathered data from 21 childcare teachers and 255 mothers of young children attending childcare centers in Incheon. Structured questionnaires were used for collecting data from the participants. The findings are as follows: First, playfulness and social competence varied by the age and gender of the young children. Boys outperformed their female counterparts in the sub-factors of playfulness such as physical spontaneity and sense of humor. Age caused a significant difference in all sub-factors including physical spontaneity, social spontaneity, cognitive spontaneity, manifest joy and sense of humor and the social competence of young children. Second, the study examined the correlations among social competence, temperament and playfulness. A positive correlation was shown between overall social competence and activity; social competence was negatively correlated with shyness but positively correlated with the sub-variables of children's playfulness. Lastly, emotionality, shyness, physical spontaneity, cognitive spontaneity, and sense of humor were variables that had serious effects on the overall social competence of young children.

This paper aims to evaluate the effects of Critical work factors on Work Motivation and Job Satisfaction of young Vietnamese employees. The four most essential work aspects were consisting of the Work environment, Employee empowerment, Salary, and Promotion opportunities. To empirically evaluate the proposed research model, the authors assemble data through conducting questionnaire interviews with young employees working in Vietnamese firms. A sample of 216 respondents was constructed using the PLS-SEM program to highlight the testing of thirteen hypotheses. The testing results indicate that four Critical work factors positively impact the job motivation of young employees, especially two factors as Salary and Promotion opportunities. Surprisingly, the hypothesis regarding the positive direct relationship between Promotion opportunities and Job satisfaction is not supported. Meanwhile, the rest influence factors have a significant connection with the Vietnamese worker's job satisfaction. The mediation role of Work motivation was also tested by examining the indirect positive relationship between four Critical work factors and Job satisfaction. This paper is the first study that focuses on young employees; hence, these research findings provide Vietnamese human resource managers some suggestions for reference, which can be considered the dynamic factors on the young Vietnamese employees.

Nowadays, with the constant enhancement in the health of the economy, the average income and living standard have accordingly increased, making the need for financial independence a favorable choice. This research aims to identify the factors affecting the financial independence of young people. The authors implement quantitative analysis, with a set of primary data collected from a survey of 2664 Vietnamese people aged from 18 to 28. The research results demonstrate the considerable impact of monetary, psychological, group-related, and family-related factors on the financial independence of young people. The results of the sample analysis provide adequate evidence to reject the correlative relationship between family and group factors and the financial independence of young people. In addition, there are 3 factors, including demographic factors, monetary factors, and psychological factors, all have varying degrees and directions of influence on young people's financial independence. Most of the mentioned variables reflect a positive effect on financial independence. The only exception is the education variable, illustrated by its negative standardized beta value. A significant difference in financial independence between genders also is reported, suggesting that males seem to have a higher level of financial independence than females.
