In this paper, availabilities of student-evaluations of team activities in the computer science basic classes were analysed. For the purpose, correlation analysis was conducted to investigate the relationships among peer-evaluation, self-evaluation, and academic achievement, and it was found that there was a statistically significant positive correlation among them. Moreover, the gap between peer-evaluation scores and self-evaluation scores was analyzed. When a one-sample t-test was performed, it was found that the gap was very significant. However, the size of the gap was not different between the two classes. That is, regardless of grade level, the students' self-evaluation scores tended to be on average higher than the evaluation scores received from peers. Finally, when analyzing the relationship between the gap in peer-evaluation and self-evaluation scores and academic achievement, there was no significant correlation between the gap in scores and academic achievement. In other words, there was no difference in the tendency of evaluation for students with high or low academic achievement. The results of the analysis shows the availability of student-evaluations of team activities in the evaluation of team-based instruction. The high correlation between self-evaluation and peer-evaluation indicates the objectivity of student-evaluation. Although it is clear that the self-evaluation score is higher on average than the score received from peers, it is more useful in terms of objectivity because it does not vary according to grade, subject, or academic achievement.

This study focused on the sex culture and the sexual rights of women, examining the gender-role stereotype that is related to the protection of the sexual rights of female college students and identifying the influence of self- esteem. The research was conducted on gender-role stereotypes, sexual assertiveness, and self-esteem among female university students attending four-year universities in Seoul and Gyeonggi. Four hundred eighty-two copies were used for analysis. The Pearson's correlation coefficient was used to identify the correlation between the variables. Multiple regression analysis was conducted to identify the mediated effects of self-esteem in the effects of gender-role stereotypes on sexual assertiveness. The Sobel test was conducted to confirm that the effects were statistically significant. The results of this study were as follows. First, the gender-role stereotype had negative correlations with self-esteem and sexual assertiveness. Self-esteem had positive correlations with sexual assertiveness. Second, self-esteem was found to be a partial mediating factor when the gender-role stereotype had a statistically significant effect on sexual assertiveness. Therefore, a coping strategy under the influence of the gender-role stereotype is necessary for improving the sexual assertiveness skill of female students. This study also suggests the need for sex role-related education programs or counseling on self-esteem.

This study was conducted to investigate the reliability and validity of the Korean self-compassion scale using data from 312 correctional workers. To validate the self-compassion scale using the collected data, correlational analysis, exploratory and confirmatory factor analysis were applied. To explore relationships between the self-compassion scale and related instruments, five instruments were used (the Korean occupational stress scale, the center for epidemiological studies depression scale, the Maslach burnout inventory scale, perceived stress scale, and the satisfaction with life scale). The results showed that the collected data better fit the 6-factor model than the 3-factor and 2-factor models. There were statistically significant relationships between the self-compassion scale and five other scales. These results suggest that the self-compassion scale is a good instrument to examine risk factors that can remain during continuous stress situations and to explore protective factors that can maintain the therapeutic relationship. The implications of this study and future research directions were also discussed.

본 논문은 벡터자기상관(VAR) 모형과 벡터자기상관이동평균(VARMA) 모형을 사용하여 명목금리와 물가(도매물가)사이의 동태적 관계를 분석한다. 명목금리와 물가사이의 정(+)의 상관관계는 소위 $\ulcorner$깁슨의 역설$\lrcorner$로 불리워지고 있는데, 실증분석 결과에 의하면 한국의 경우 깁슨의 역설은 존재하지 않는 것으로 보여진다. 과거의 많은 연구들이 $\ulcorner$깁슨의 역설$\lrcorner$을 지지하는 실증결과들을 발견한 것은 관련변수들의 안정성(stationarity)을 고려치 않은 것으로 판단된다. 본 논문에서처럼 관련변수들의 안정성을 얻기위해 수준변수(예를들면, 도매물가지수) 대신에 차분되거나 증가율을 사용하고, 금리 및 물가이외에 두변수에 영향을 줄 수 있는 변수(예를들면, 통화변수)들을 포함하는 다변수 모형을 이용한다면 우리나라에서는 $\ulcorner$깁슨의 역설$\lrcorner$은 발견되지 않은 것으로 보여진다. 즉, 회사채 수익율과 도매물가상승율을 명목금리와 물가변수로 각각 사용하고, $1972.III{\sim}1991.III$사이의 분기별 자료를 대상으로 분석한 결과, 두변수 사이의 관계는 일방적 인과관계보다는 독립적인 관계로 나타나고 있다.

The purpose of this study is to verify how 7 sentiment domains extracted through sentiment analysis from social media have an influence on business performance. It consists of three phases. In phase I, we constructed the sentiment lexicon after crawling 45,447 pieces of VOC (Voice of the Customer) on 26 auto companies from the car community and extracting the POS information and built a seven-sensitive domains. In phase II, in order to retain the reliability of experimental data, we examined auto-correlation analysis and PCA. In phase III, we investigated how 7 domains impact on the market share of three major (GM, FCA, and VOLKSWAGEN) auto companies by using linear regression analysis. The findings from the auto-correlation analysis proved auto-correlation and the sequence of the sentiments, and the results from PCA reported the 7 sentiments connected with positivity, negativity and neutrality. As a result of linear regression analysis on model 1, we indentified that the sentimental factors have a significant influence on the actual market share. In particular, not only posotive and negative sentiment domains, but neutral sentiment had significantly impacted on auto market share. As we apply the availability of data to the market, and take advantage of auto-correlation of the market-related information and the sentiment, the findings will be a huge contribution to other researches on sentiment analysis as well as actual business performances in various ways.
