To investigate the characteristics of $Gammakgeolli$ to which processed forms of persimmon were added, $Gokkam$, $Gammalaengi$, whole powder, peel powder, and paste were used as various processed forms. The moisture, total polyphenol, and soluble-solid contents of the persimmon used for making $Gammakgeolli$ showed a big difference according to the processed form of persimmon, and influenced the total polyphenol and alcohol contents of the $Gammakgeolli$. The pH and total acid of the $Gammakgeolli$, which were 3.7~4.1 and 0.20~0.29% (w/v), respectively, were similar to those of commercial $Makgeolli$. The amino acidity increased on the fifth day after fermentation from that on the third day, and showed relatively high levels in the whole power, peel power, and paste. The volatile-acid contents of the $Gammakgeolli$s were within the range of 80~100 ppm and showed the highest level in the persimmon-paste-treated sample. Among the major organic acids of $Gammakgeolli$ (oxalic, citric, tartaric, malic, succinic, lactic, and acetic acid), lactic acid had the highest concentration. The $Gammakgeolli$ to which hole power or paste was added showed a high level of yellowness and a good color in the sensatory evaluation. In the sensory evaluation (selection rate) of the taste and overall acceptability, the $Gammakgeolli$ treated with $Gammalaengi$ was the best.

This study examines the mediating effects of self-efficacy between self-differentiation and depression by analyzing 105 parents who have at least one child with a disability. Regression analysis confirmed all hypothesis between self-differentiation, self-efficacy, and depression. There exists partially or complete mediation. That is the indirect effect on depression, self-efficacy explains the relationships between self-differentiation and depression to be as minimum as 24 percent to as maximum as 100 percent. This demonstrates that the self-efficacy significantly affects the relationship between self-differentiation and depression. Findings of this study recommend that self-efficacy should be enhanced through improving the level of self-differentiation. The results also imply that rehabilitation counselors need to understand the way of improving self-efficacy as well as the fact that the influencing factors of self-differentiation on self-efficacy is important. The findings of this study are informative for researchers, educators, and clinicians for mental health and psychological rehabilitation who assist the parents of children with disabilities.

Since there are growing concerns regarding personal information, users have perceived the importance of it. It makes users try to manage and control personal information by their own intentions. Therefore, we assume users now have begun to perceive psychological ownership on personal information. A main objective of this study is to identitythe relationship between accountability, self-identity, self-efficacy and sense of belongingness and psychological ownership on personal information. We conduct an online-basedsurvey and establish a structural equation model for testing hypothesis. The results show that users' accountability, self-identity and sense of belongingness positively influence to psychological ownership on personal information. Additionally, users' perceived psychological ownership on personal information increase their concern for information privacy. This study suggests a new concept as 'perceived psychological ownership on personal information' to explain for intentions of their psychological possessions toward personal information. The findings of this study can provide a way for how firms have to require clients' personal information with increasing their satisfactions.
