The purpose of this study was to examine the relationships among students’ perceived parenting behavior, social emotional competencies, and parental expectations. In this study, social and emotional competencies were categorized into two different dimensions: self and social. A survey was administered to 389 fifth and sixth grade students from 4 elementary schools in Seoul, Korea. Hierarchical multiple regression analyses were conducted to examine the moderating effects of perceived parental expectations. Results suggest that supportive parenting behaviors and behavioral control behaviors promote students’ social emotional competencies. On the other hand, psychological control behaviors undermine the development of social emotional competencies on self-dimension. According to analysis of moderating effects, for students with high parental expectations, it was found that the more supportive parenting behavior, the more likely the children were to cultivate self and social dimensions of social-emotional competencies. Findings from our study suggest that parents need to recognize that appropriate parenting behavior is of utmost importance in the development of children’s social-emotional competencies.

Plasma is 4th state of matters, which consists of electrons, neutral, and ionized particles. In biomedical research, cold plasma, which is generated in atmospheric condition, has been applied to disinfect microorganisms such as bacteria and yeast cells. Because of its low temperature condition, the heat-sensitive medical device can be easily sterilized by the cold plasma treatment. In recent years, the effects of plasma on mammalian cells have arisen as a new issue. Generally, plasma induces intensity dependent necrotic cell death. In this research, we investigate the feasibility of cold plasma treatment for cancer therapy by conducting comparative study of plasma effects on normal and cancer cells. We use THLE-2 (human liver normal cell) and SK-Hep1 (human liver metathetic cancer cell) as our target cells. The needle type of cold plasma is generated by the Helium plasma device. Two types of cells have different onset plasma conditions for the necrosis, which may be explained by difference in electrical properties of these two cell types.
