This paper explores the relationship between firm-specific volatility and some firm characteristics such as size, the market-to-book ratio of equity, PER, PBR, PCR, PSR and turnover in KOSDAQ market. In addition, I investigate whether portfolios with difference to realized range-based volatility and firm-specific volatility have different investment performance using CAPM and FF-3 factor model. The main findings of this study can be summarized as follows. First, firm-specific volatility have mostly positive relationship between firm-specific volatility and some firm characteristics. Second, this study found that realized range-based volatility and firm-specific volatility are positively related to expected return. It means that portfolios with high idiosyncratic volatility have significantly higher expected return than portfolios with low firm-specific volatility.

The purpose of this study is to identify the relationship among the self-directed learning ability, academic self-efficacy and academic achievement of elementary school students. The subjects of this study were 197 sixth graders. The results of this study were as follows. First, the correlations among self-directed learning ability, academic self-efficacy and academic achievement were significant. Second, among the variables of self-directed learning ability and academic self-efficacy, self-confidence, preference for task difficulty, self-understanding of learner and independent mind of learning were positively related to academic achievement. These results imply the need for measures to increase these variables of academic efficacy and self-directed learning ability in the field of education in order to improve students' academic achievement.

This study aims to examine the suggestions by studies that family predictors are related to developmental outcomes more strongly for children reared principally by their parents compared to those with extensive child care experience. Zero-order correlations between family predictors and developmental outcomes were conducted and the significance of differences in correlation coefficients between the two child care groups were examined. There was no evidence that there exist systematic differences between the two groups in predictive power of family factors except a few exceptions. At 2 years, social parenting style was more strongly associated with communication ability in the extensive child care group. At 3 years, some HOME subscales were related to a child's expressive and receptive vocabulary skills in significantly greater magnitudes in the mother care group. The findings also implied the potential contribution of child care environment on developmental outcomes for those who spend extensive hours in nonmaternal care.

This research aimed to investigate the relations of perfectionism and multicultural attitude upon a premise that sub-factors of the perfectionism : self-oriented perfectionism, other-oriented perfectionism and socially-prescribed perfectionism are related to multicultural attitude and to examine the moderation effect of self-acceptance on the relation between perfectionism and multicultural attitude. The questionnaires designed to measure multidimensional perfectionism, unconditional self-acceptance and multicultural attitude were administered to 258 office workers in Seoul and Gyeoggi-Do. The results from correlation analysis and regression analysis were as followed. First, sub-factors of the perfectionism was partially associated with sub-factors of multicultural attitude. In particular two sub-factors of the perfectionism : 'self-oriented perfectionism', 'other-oriented perfectionism' yielded effect on multicultural attitude, controlling the effects of other subscales. Second, unconditional self-acceptance moderated the relation between 'self oriented perfectionism' and sub-factor of the multicultural attitude : 'recognizing difference'. And unconditional self-acceptance moderated the relation between 'socially prescribed perfectionism' and sub-factors of the multicultural attitude : 'recognizing difference', 'openness and acceptance'. This present findings not only extend understandings about relationship between perfectionism and multicultural attitude by examining self-concept : unconditional self-acceptance but also provide that it isn't helpful that further support and rationale for unconditional self-acceptance as intervention for targets to focus in counseling process for those who suffer from perfectionism.

This study conducted a meta-analysis to examine syntagmatically on the variables related with recovery among persons with mental illness in Korea. In order to do a meta-analysis, theses and dissertations published between 1999 and 2018 in Korea were reviewed systematically and a total of 24 including studies were selected. Using Comprehensive Meta Analysis (CMA) 3.0 software, this study calculated average effect size and moderator variables related with recovery among persons with mental illness. Results were as follows. First, this study identified a total of 16 variables related with recovery among persons with mental illness. Second, the results indicated that variables which showed large effect sizes included social support(r=.575), empowerment(r=.555), self-efficacy(r=.544), social skill(r=.500), relationship with social worker(r=.482), stigma(r=-.446), family support(r=.418). Third, variables with medium effect sizes included interpersonal relationship capacity (r=.391), agency service satisfaction(r=.366), insight(r=.373) and symptom(r=-.239). Fourth, variables with small effect sizes included work experience(r=.188). Fifth, moderator analyses were conducted utilizing characteristics of residence state (community or mental hospital). Moderator effects were identified in the social support and family support. Based on the findings, theoretical and clinical implications for the recovery among persons with mental illness in Korea were discussed.

본 연구는 청소년기 부모-자녀관계 및 노부모-성인자녀간 결속도가 노인의 생활 만 족도에 미치는 영향을 분석하고 각 변인들간의 인관관계를 알아보고자 하는데 그 목적이 있 다 본 연구의 결과는 다음과 같다 1)노부모-성인자녀간 결속도는 비교적 높은 편이었으며 청소년기 부모-자녀관계가 애정적.권위적.자율적이고 갈등의 정도가 낮았을수록 높았다. 2) 노인의생활만족도는 청소년기 부모-자녀관계가 애정적.자율적이었으며 갈등의정도가 낮 았을수록 높게 나타났고 권위적 관계였을수록 과거 생활만족도는 높았고 미래 생활만족도는 낮았다 또한 노인의 생활만족도는 현재 성인자녀가 접촉적.정서적 .일치적.기능적.규범 적 결속이 높을수록 높았으며 구조적 결속에 따라서는 차이가 없었다 3) 노인의 생활만족도 에 가장 큰 영향을 미치는 변인은 청소년기 부모-자녀관계중 갈등적 관계였다.

한국산 송사리 (Oryzias)속의 송사리 (O. latipes)와 대륙송사리(O. sinensis)의 집단 내 유전적 변이 및 종간 유연관계를 밝히고자 남한의 16개집단과 일본산 송사리(O. latipes) 1개 집단 등 총 17개 집단에 대한 isozyme 분석을 실시하였다. Isozyme 분석 결과 17개의 효소 및 비효소단백질에서 총 32개의 유전자를 검출한 결과, 전체 유전자중 Est-1과 Est-3 는 종 특유의 유전적 표식인자(genetic marker)였다. 송사리집단 중 진도집단의 유전적 변이 가 가장 낮았으며(Ho=0.011, He=0.043), 대륙송사리 서천집단의 유전적 변이가 가장 높았 다.(Ho=0.114, He=0.124). 한국산 송사리 11개 집단의 평균 유전적 변이 정도는 P=12.7%, Ho=0.029, He=0.042, 대륙송사리 5개 집단의 평균 유전적 변이정도는 P=26.3%, Ho=0.082, He=0.097로 각각 나타나 대륙송사리집단의 유전적 변이 정도가 송사리집단에 비해 약 2.5배 정도 높았고 일본산 송사리의 유전적 변이 정도는 P=15.6%, Ho=0.073, He=0.068로 나타났 다. 한국산 송사리와 일본산 송사리와의 유연관계는 S=0.761(D=0.243)로 나타나 유전적으로 뚜렷한 별개의 분류군으로 생각되며, 대륙송사리와 송사리간의 종간 유전적 근연치는 S=0.648(D=0.389)로 일반적인 척추동물의 종간 유전적 분화 수준을 나타냈다.

본 연구에서는 액착이론 및 가족발달적 접근을 바탕으로 하여 성인딸과 어머니의 상대방에대한 애착, 그들의 상호작용, 주거상 거리, 딸의 결혼 및 부모기로의 변화(tran-sition)등 성인 모녀 관계에서 중요한 제 변인들 간의 관계를 알아보았다. 본 연구에서는 유목적적 편의표집 방법을 이용하여 100쌍의 성인 딸과 그들의 친 어머니를 대상으로 선정하였으며 횡단적 비교를 위하여 성인 딸의 결혼 여부 및 자녀 유무에 따라 다음과 같은 3집단으로 구분하였다 : 미혼의 딸과 그들의 어머니(미혼기) 자녀가 없는 기혼의 딸과 그들 의 어머니(신혼기), 자녀가 있는 기혼의딸과 그들의 어머니(부모기), 성인 모녀 애착 질문지를 이용하여 얻은 응답을 토대로 성인 딸과 어머니의 애착에 영향을 미치는 변인들을 중다회귀분석한 결과는 다음과 같다. 성인모녀 애착은 상호 호혜적이었다. 성인 모녀간의 상호작용, 모녀간 애착의 차이, 딸의 결혼여부는 성인 딸과 어머니의 애착에 유의한 영향을 미쳤는데, 특히 이들 변인과 관련하여 성인 모녀가 서로에 대한 애착을 지각하는 양상에는 차이가 있었다. 모녀간 주거상 거리는 성인 모녀 액착에 아무런 영향을 미치지 않았으며 이것은 서 인기의 상장적 애착을 의미한다고 할 수 있다.

This study investigated the relationships of preschool children's interactive peer play, stimulated home environment, and mother-child interaction. A total of 255 children were selected in this study. Data were analyzed with Pearson correlations and covariance structural analysis by using SPSS and AMOS, a statistical program for structural equation modeling. The major findings of this study were as follows: First, interactive peer play was associated with stimulated home environment and mother-child interaction. Second, the results confirmed the pathway from stimulated home environment via mother-child interaction to interactive peer play showing a significantly good model fit. The paths from stimulated home environment to children's interactive peer play were mediated by mother-child interaction.
