A number of Brain-Computer Interface (BCI) studies have been performed to assess the cognitive status through EEG signal. However, there are a few studies trying to prevent user from unexpected safety-accident in BCI study. The EEGs were collected from 19 subjects who participated in two experiments (rest & event-related potential measurement). There was significant difference in EEG changes of both spontaneous and event-related potential. Beta power and P300 latency may be useful as a biomarker for prevention of response to safety-accident.

The purpose of this research was to examine the concurrent validity of the Nalongyee children's achievement motivation test by studying its relationship to a children's school readiness test. The subjects were 335 preschool children (171 urban and 164 rural) selected from 8 public and 7 private kindergartens located in two metropolitan areas (Seoul and Pusan) and 5 rural counties in Kyungsang Nam Do. Instruments included the Nalongyee Children's Achievement Motivation Test by the author and the School Readiness "Lest by Unhai Rhee. Data were analyzed by Pearson r and Z-test. Readiness was positively related to the total score and sub-areas of achievement motivation (.10-.43). Sub-areas of the achievement motivation test were related to each of the 4 factors of the readiness test. The correlations ranged from .00-.35 with the personal-social response factor, .00-.26 with the associative vocabulary factor, .05-.31 with the number concept factor, and .03-.37 with the perception factor. Significant differences in correlations were found between urban and rural areas for self-confidence, interest in learning, interest in kindergarten and physical competence.

This research focused on the cause and effect relationship between various factors related to teen-age pregnancy. A total of 130 unwed mothers were interviewed regarding details of their pregnancies. Path analysis showed that knowledge of contraception and premarital sexual attitudes were the important factors affecting the premarital sexual behaviors directly. It was also shown that the sexual attitudes of friendship groups indirectly affects premarital sexual behaviors through the path of the premarital sexual attitudes. When sexual attitudes of the friendship group is open, premarital sexual attitudes become open, causing the increase in premarital sexual behaviors. Premarital sexual behaviors and the knowledge of contraception did not have a statistical effect on the number of pregnancies.

This study investigated the relations among maternal cognition, maternal supervisory/monitoring behaviors, and their children's peer competence. The participants were 40 kindergarten children and their mothers. The mothers completed a questionnaire concerning maternal beliefs about children's social skills. Also their supervisory/monitoring behaviors were observed in the context of child-peer interactions. Children's peer competence was measured using a sociometric status measure and a peer acceptance rating scale. Maternal beliefs were related both to the quantity/quality of maternal supervisory/monitoring behaviors and to children's peer competence. Maternal supervisory/monitoring behaviors were also related to children's actual peer competence.

The relations between family functioning (cohesion, conflicts, family sociability, and democratic family style) and self-esteem and loneliness in adolescents were examined in a sample of 485 2nd-grade high school students (256 boys and 229 girls). Data were collected using three questionnaires on the loneliness, family functioning, and self-esteem of adolescents. Family functioning and self-esteem were significantly related to loneliness both in adolescent boys and girls. Adolescents experienced less loneliness when family cohesion and sociability were higher, conflicts were lower, the family style was more democratic, and self-esteem was higher. Family functioning was also related to self-esteem. The more functional the family, the higher the self-esteem of adolescents. Self-esteem played a partly mediating role in the relation between family functioning and loneliness only for boys. This emphasizes the influential role of self-esteem on loneliness.

This study examined whether children's peer representations are associated with peer acceptance and whether attributions and goals are related to representations about behavioral responses in ambiguous provocation and conflict situations. The subjects were 119 5th-grade children responded to 4 hypothetical situations. Results indicated that children's positive representations about peer conduct in ambiguous provocations were related to their higher level of peer acceptance, and positive representations about a friend in conflict situations were associated with their perceived positive qualities of friendship. Children's positive attribution and relational goal orientation were associated with relational behavioral responses. Gender differences were found for some goals and behavioral responses, with girls displaying a more relational goal and behavioral response orientation than boys.

The subjects were 143 juvenile deliquents in jail, aged 16 to 19, and 347 9th, 10th, 11th, 12th grade students who resided in low income areas in Seoul and Taegu. The research data were collected by structured questionnaire. 143 juvenile delinquents and 87 students whose degree of deliquency was more than M+(0.5*S.D) were selected as the final data source. The statistical methods were frequency percentile, pearson's correlation, one-way ANOVA. Scheffe'test and multiple regression analysis. The major findings showed that (1) juvenile deliquency was significantly related to father-closed communication type. (2) juvenile deliquency was significantly related to low family cohesion and adaptability, (3) the family cohesion and adaptability was positively correlated with parent-adolescent communication. Father-adolescent communication had more important effect upon the family cohesion and adaptability than mother-adolescent communication.

This study investigated how perceived social support, self-esteem and parenting attitudes of mothers relates to children's social competence and explored the mediating role of parenting attitudes in multicultural families. Participants were 67 immigrant women and their children aged 4-6. Instruments were the Social Support Scale (Park, 1985), Maternal Behavior Instrument (Lee, 1986), Self-Esteem Scale (Rosenberg, 1965) and Social Competence Scale (Doh & Falbo, 1994). Data were analyzed by Pearson's Correlation and Structural Equation Modeling (SEM). Results indicated that social support perceived by mothers related positively to their self-esteem and positive parenting, and to children's social competence. Mothers' self-esteem related positively to their positive parenting and to children's social competence. Maternal parenting behavior mediated the effects of social support and self-esteem on children's social competence.

The purpose of this study is to investigate the relationships which may exist between interpersonal relationships, depression, anxiety, and self-acceptance. This study also examines whether self-acceptance has any moderating effects on the relationships between interpersonal relationships, depression, and anxiety. The subjects of this study consisted of 400 high school students and the study focused on reporting their levels of interpersonal relationships, depression, anxiety, and self acceptance. The results indicate that depression and anxiety are negatively related to interpersonal relationships and self-acceptance. Interpersonal relationships are positively related to self acceptance. In other words, the more negative the interpersonal relationships, the greater the levels of depression and anxiety. The results also indicate that self-acceptance functions as a protective factor for high school students who have problems with depression and anxiety in their interpersonal relationships.
