This study examined the effects of value-in-behavior toward pro-social consumption behavior on consumers' pro-social practices and the moderating effects of consumer's social capital based on trust and reciprocity that enhances collective actions to seek socially common values. The result showed that the value-in-behavior toward pro-social consumption was positive in general, and altruistic value was the highest, followed by emotional value, social value, and functional value. The pro-social behaviors of age groups were significantly different. In all pro-social behaviors, the older group was more active, except for the rejection of the unfair business. The result also showed that the functional value and emotional value have significant effects on consumer's pro-social practices. The interaction effects between trust and emotional value and between reciprocity and functional value were significant. Based on these results, the theoretical and practical implications for facilitating the transition to the direction of consumer's role in making positive social impacts.

In maize, knowledge of genetic diversity and genetic relationships among elite inbred lines is an significant impact on the selection of parental lines for hybrid varieties. Genetic diversity and genetic relationships among 11 parental inbred lines of Korean waxy and normal corn varieties were analyzed using 50 SSR markers distributed over the whole genome. A total of 171 allele bands were detected with an average of 3.4 alleles per locus. Number of allele bands per locus ranged from two to six and gene diversity varied from 0.165 to 0.900 with an average of 0.596 depending on the SSR loci. The cluster tree recognized three major groups with 61.6% genetic similarity. Group I includes 7 inbred lines (KL103, HW1, HW4, HW6, HW7, HW8, HW9), with similarity coefficients of between 0.616 and 0.730. Group II includes 2 inbred lines (HF1, HF2), with similarity coefficients of 0.959. Group III includes 2 inbred lines (HW3, HW5), with similarity coefficients of 0.713. The present study indicates that the SSR markers chosen for this analysis are effective for the assessment of genetic diversity and genetic relationships among 11 parental inbred lines.

The purpose of this study was to examine the effect of young children's verbal expression on their prosocial behaviors. The subjects were 44 four-year-olds and 42 five-year- olds in nine kindergartens and daycare centers located in Gyeonggi-do. The instruments used were Verbal Expressiveness Inventory(Jang, 1981) and PBSYC for teachers(Kim, 2003). The major findings of the study were as follows: Concerning the correlations between their verbal expression and prosocial behavior, those who had better verbal expression showed more prosocial behavior. The relationships between the subfactors of verbal expression and those of prosocial behavior were inconsistent to some extent, but there was a positive correlation between the two overall. So it could be said that a better verbal expresson leads to better prosocial behavior. From the findings of the study on the effect of the verbal expression on prosocial behavior, it can be concluded that young children who have better verbal expression are more excellent at building a good peer relationship, helping their peers, being considerate, making themselves accessible, sharing their own belongings with peers and regulating their own emotions. This study is expected to assist early childhood education institutions to provide young children with a variety of educational activities geared toward improving verbal expression to improve their prosocial behaviors. Also, this study is expected to help teachers to improve the prosocial behavior of young children in diverse ways.

This study structurally analyzes the relations between children's pet attachment, empathy ability, and prosociality. The results are used to investigate the relations between pet attachment and empathy ability, which have recently emerged as important variables that affect children's prosociality. Data were collected about pet attachment, empathy ability, and prosociality from 209 elementary students in Daejeon who had experience with raising pets. SPSS 22.0 software was used for descriptive statistical analysis, correlation analysis, and reliability analysis, and AMOS 22.0 was used for confirmatory factor analysis and to examine the structural equation model. According to the analyses, children's pet attachment did not affect their prosociality but did influence their empathy ability. Children's empathy ability affected their prosociality and had a mediating effect on the relation between their pet attachment and prosociality. The results indicate that children's pet attachment and empathy ability are essential factors that influence prosociality. To improve prosociality, efforts should be made increase pet attachment and empathy ability. The study results can be used as a theoretical and practical fundamental basis for plans to improve children's pet attachment, empathy ability, and prosociality.

In many enterprises, the extent and the frequency of damages incurred due to the unethical behavior of the members of the organization have not reduced, but rather the magnitude and frequency of damages have been increasing. Research at an organizational level is necessary at this point in time, to investigate the contributing variables that cause this unethical behavior, the measures to manage them, and the control variables that can reduce unethical pro-organizational behavior. Therefore, this study seeks to explore perceived organizational support and psychological entitlement as leading factors of unethical pro-organizational behavior, based on the theory of social exchange, and to examine the reaction mechanism between these variables. This is particularly because a large number of the current labor force belongs to the millennial generation (born after 1978) or Generation Y, and their sense of psychological entitlement has been problematic in their organization. The effect of perceived organizational support on unethical pro-organizational behavior and the effect of psychological entitlement on unethical pro-organizational behavior were examined through a review of existing literature, and an empirical analysis was conducted to investigate the moderating effects of psychological entitlement on perceived organizational support and unethical pro-organizational behavior. A regression analysis was conducted based on the valid data of 185 members of an organization who belong to the millennial generation, and the analysis results showed that a sense of psychological entitlement had a moderating effect between perceived organizational support and unethical pro-organizational behavior. Based on these findings, this paper proposes theoretical and practical implications for unethical pro-organizational behavior and psychological entitlement, and hopes to contribute to expanding research in this area.

The fruit yield and morpholgical characters of F$_{1}$ hybrids between Capscium annuum L. 'California Wonder', four native Japanese cultivars, and three Korean F$_{1}$ cultuvars were evaluated and the results compared with parental cultivars. The F$_{1}$ hybrids obtained by crossing 'California Wonder' and native Japanese cultivars flowered 3 days earlier on average compared to parental cultivars. The yields of F$_{1}$ hydrids were higher than those of the parental cultivars, especially when one of the parents was 'California Wonder'. Also F$_{1}$ hybrid whose one parent was 'California Wonder' and 'Fushimi Amanaga' gave the highest fruit yield. The number of locules and seeds per fruit from of the 'California Wonder' hybrids whose one parent was 'California Wonder' was more than of the native Japanese cultivars. The plant height in F$_{1}$ hybrids obtained by crossing between 'California Wonder' and four native Japanese cultivars tended to be higher than that of the parental cultivars.

The objective of this experiment was determined to investigate the effect of the planting ratio of Male Sterility (MS) to Restorer Line (RL) and harvesting time on fatty acid compositions under $F_1$ seed production of Brassica napus L. For rapeseed seed production, two experiments were conducted in the open fields. One experiment studied planting ratios of MS to RL (4:2, 10:2, or 10:1) were planted and investigated fatty acid composition at 40, 45, 50, 55, and 60 days after flowering, the other $F_2$ seeds were analyzed on fatty acid compositions of harvested seeds at five sequential stages. The results showed that fatty acid compositions of developing seeds were influenced by MS:RL planting ratios and $F_2$ hybrid treatments and contaminated level of fatty acid compositions, erucic acid, were unaffected by planting ratio of MS to RL. Fatty acid compositions such as palmitic acid (C16:0), stearic acid (C18:0) and linoleic acid (C18:2) contents decreased during seed maturation period in $1^{st}$ and $2^{nd}$ experiments. In contrast, oleic acid (C18:1) content relatively increased up to 55days after flowering. At day 60 after flowering, oleic acid content was unaffected by MS:RL planting ratios and $F_2$ seeds treatments. Aspects of related gene expression of fatty acid synthesis such as SAD, FAD1 and FAD2 were followed exactly to changes of fatty acid composition during seed maturation. These results suggest that MS ratio may be enlarged and RL may be reduced, indicating this ratio will be useful for rape seed production.

The 120 participants of this study were 5- and 9-year-old children and their mothers. Children responded to 24 prosocial moral reasoning dilemmas and 8 prosocial decision-making tasks. Mothers' prosocial moral reasoning was assessed with questionnaires. Level of moral reasoning was higher in distant than in close relationships. 5-year-olds in preoperational stage used the complex situational cues in their reasoning, and prosocial moral reasoning of 9-year-olds was positively related to mothers' prosocial moral reasoning in the situation with conditions of distant relationship, low costs, and internal responsibility. Children made more helping decisions in close than in distant relationship situations, low rather than high cost situations, and external rather than internal responsibility situations. 5-year-olds whose mothers were high in level of prosocial moral reasoning were more helpful.

This study was designed to recognize the importance of prosocial behavior, aimed at developing and utilizing a tea ceremony education program to foster prosocial behavior in children to be used in pre-school during early childhood when basic behavioral patterns are established. The sample was composed of 90 children from K pre-school located in GangDong-Gu and 90 children from K pre-school located in Jung-Gu. Their ages varied from 3 to 5 years old and the family's financial position was approximately middle class. The results were as follows, the change in children's prosocial behavior according to the group showed that childhood tea ceremony education through the tea ceremony education program affected the improvement in children's prosocial behavior. This suggests that childhood tea ceremony education are useful for improving children's basic habits and prosocial behavior, as well as character education.
