In most self-incompatible plant species, recognition of self-pollen is controlled by a single locus, termed the S-locus. The self-incompatibility (SI) system in Brassica is controlled sporophytically by multiple alleles at a single locus, designated as S, and involves cell-cell communication between male and female. Two highly polymorphic S locus genes, SLG (S locus glycoprotein) and SRK (S receptor kinase), have been identified, both of which are expressed predominantly in the stigmatic papillar cell. Gain-of-function experiments have demonstrated that SRK solely determines S haplotype-specificity of the stigma, while SLG enhances the recognition reaction of SI. The sequence analysis of the S locus genomic region of B. campestris (syn. rapa) has led to the identification of an anther-specific gene, designated as SP11/SCR, which is the male S determinant. Molecular analysis has demonstrated that the dominance relationships between S alleles in the stigma were determined by SRK itself, but not by the relative expression level. In contrast, the expression of SP11/SCR from the recessive S allele was specifically suppressed in the S heterozygote, suggesting that the dominance relationships in pollen were determined by the expression level of SP11/SCR. Furthermore, recent studies on recessive allele-specific DNA methylation of Brassica self-incompatibility alleles demonstrate that DNA methylation patterns in plants can vary temporally and spatially in each generation. In this review, we firstly present overview of self incompatibility system in Brassica and then describe dominance relationships in Brassica self- incompatibility regulated by allele-specific DNA methylation.

The purpose of this study was to examine the effect of emotion regulation strategy on posttraumatic growth and to confirm serial multiple mediating effects of self disclosure on a traumatic experience and social support in relationship between suppression strategy of emotional expression and posttraumatic growth. A survey was conducted for adults over the age of 18. Data of 663 adults (222 men, 441 women) were analyzed. According to analysis by using SPSS Process Macro, the less suppression strategy of emotional expression was used, the higher posttraumatic growth was. Simple mediating effect of self disclosure was confirmed between suppression strategy of emotional expression and posttraumatic growth. Serial multiple mediating effects of self disclosure and social support were shown in relationship between suppression strategy of emotional expression and posttraumatic growth. It means that the more people who use less suppression of emotional expression as their emotion regulation strategy, the more they disclose on their traumatic experience, then, they will receive emotional comfort and support from the people around, finally reaching posttraumatic growth. The importance of self disclosure and social support on posttraumatic growth was verified. Counseling intervention method was suggested for involuntary clients who usually suppress emotional expression, to enhance their posttraumatic growth. Lastly, significance and limitations of this study were suggested for follow-up studies.

The purpose of this analysis is to investigate the effect of leading characters in picture books on self concept in children. For this study, we selected a total of 55 picture books, all of which were best sellers in four internet book stores. The method used for the study was based on content analysis. The results of this analysis were as follows: First, the gender of leading characters was male more often than female, and the majority of picture books were creative story books and translation books. Second, subordinate parts related to the self-concept were most frequently found in the social self-concept. Social self-concept was positively expressed through the relationship between friend and family characters in story books. Cognitive self-concept was the least. Third, when the frequency of positive and negative expressions in picture books was analyzed, the social self-concept was found to be positively expressed in the subordinate parts of relationships between friends and family. The social self-concept was negatively expressed, however, in the subordinate parts of relationship between non-significant others, and the emotional self-concept was also negatively expressed in the subordinate parts of the emotional recognition and expression. In summary. instances of cognitive self-concept and positive expression were found to be more significant than negative ones.

The purpose of this study was to examine the mediating effects of self-perceived competence on the relation between covert narcissism and dysfunctional anger expression of middle school students. The data collected from the questionnaire was analyzed by using the SPSS 20.0 program. The main results were as follows: Firstly, covert narcissism has statistically a significantly negative correlation to self-perceived competency. It also has a significantly positive correlation to dysfunctional anger expression. Secondly, the results revealed that the relation between covert narcissism and dysfunctional anger expression was partially mediated by 'physical appearance', 'behavioral conduct', 'social acceptance' and 'athletic ability' competencies. The result of this study is significant for providing the basic data for understanding the characteristics of the middle school students who have narcissistic tendencies due to a weak inner-self as well as helping their adaptational relationship through functional anger expressions.

Purpose: Art program has been found to enhance mood such as increasing motivation, self-expression and decreasing depression in older adults. This study was conducted to investigate the effects of clay art and drawing on depression and self-expression among elderly people at a long-term care center. Methods: The research was a pre-test and post-test non-equivalent design. Sixty older patients (clay art program=28. Drawing art program=32) over the age of 65 were recruited from 2 long-term care hospitals to participate in the 5 weeks program. Each group was scheduled with 10,120-minute evaluation sessions, twice per week. Test measures were completed before and after the 5 week intervention period for all participants. The data was collected from April 27 to May 29, 2015. It was analyzed with SPSS 22.0 using chi-square, t-test and paired t-test. Results: There were no significant difference in the levels of depression (t=0.21, p=.830) and total score of self-expression (t=-0.10, p=.919) between the two groups. However, the pre-post scores of self-expression in the clay art program (t=0.22, p=.826) were improved compared to the drawing art program (t=0.80, p=.430). Conclusion: Further studies are needed to evaluate the effectiveness of clay art program for extended senior care applications.

Compared with the research on consumer engagement in brand community, the research on consumer engagement in brand public has been relatively less. This research aimed at exploring how brand public characteristics such as information variety, various communications and no limitation in expressing self affect the brand public engagement. 274 questionnaires answered by Chinese consumers are used to conduct analysis. Principal component analysis is used to test the reliability and validity of each construct, and structural equation model is used to test hypotheses. The study finds the positive effects of information variety on information benefits, those of various communications on social benefits, and also positive roles of no limitation in expressing self to brand-related self-expression motivation. And each of the information benefits, social benefits and brand-related self-expression motivation is proved to positively affect brand public engagement. The study implies that marketers should give attention to characteristics of brand public, and provide the ways by which members of brand public engage the brand. Additionally, marketers should pay more attention to both direct and indirect engagement activities of consumers toward brand public in social media to better understand their target consumers.
