The purpose of this study was to explore the latent profiles of social achievement goals and to investigate the differences in peer status (perceived popularity, social preference) and aggression (overt, relational, cyber) among those profile groups. Social achievement goals and cyber aggression data was acquired through self-reporting, and perceived popularity, social preference, and overt and relational aggression were assessed through peer nomination. Applying the latent profile analysis(LPA) to 1,239 elementary school students, three distinct groups of social achievement goals were identified: a development-oriented achievement goal group, an average social goal group, and a overall-high social achievement goal group. Using logistic regression analysis, the relationships between the latent group, peer status, and aggression were examined. The result indicated that the higher the social preference, the lower the probability of belonging to the 'overall-high social achievement goal group'. And the higher the cyber aggression, the lower the probability of belonging to the 'development-oriented achievement goal group'. In addition, the higher the relational aggression of the second time, the higher the probability of belonging to the 'overall-high social achievement goal group' as compared to the 'average social goal group'.

최근 도시화가 진행되면서 지표의 불투수화가 급격하게 진행되고 강우의 지표면 유출량이 급격하게 증가하여, 강수 시 첨두유출 시간이 감소하고 단기간 집중유출이 증대되어 폭우로 인한 도시 홍수등이 발생하고 있다. 이러한 현상에 효과적으로 적응하기 위해 환경적으로 지속가능한 도시 개발을 위한 그린인프라(GI, Green Infrastructure) 및 저영향개발기법(LID, Low Impact Developpment)이 국내에 도입되고 있다. 하지만 아직까지 투수성 포장의 물순환 성능 평가 및 설계 방법에 대한 기준이 명확하지 않으며, 많은 경우 투수성 포장의 적용은 유출저감효과에 대한 정량적 해석 없이 적용되고 있는 실정이다. 이에 본 연구에서는 경남 양산시 부산대학교 제 2 캠퍼스에 있는 "한국형 GI&LID 실증실험단지"에 투수 도로형 실증실험시설을 구축하였다. 실험 시설은 불투수 아스팔트와 투수 아스팔트, 불투수 콘크리트와 투수 콘크리트 비교실험 할 수 있으며 도로표면 유출수 및 침투수에 대한 유량 및 수질 측정 모니터링을 통해 침투효과 및 특성을 분석할 수 있으며 차후 투수성 포장의 클로깅 현상으로 인한 투수성능의 감소 등 여러 가지 실험을 할 수 있을 것이다.

The purpose of the present study was to examine the relationship between individual values, nature-relatedness, and happiness in a sample of Korean university students(N=224). Specially, we used Schwartz's PVQ, life satisfaction, positive affect, psychological well-being, social well-being, and Korean Happiness scale to measure values and happiness. According to the bivariate correlational analysis, generally, there were positive correlation between benevolence, self-direction, universalism, stimulation and one of 5 happiness measurements and there was negative correlation between achievement and life satisfaction. Nature-relatedness were positively related with five types of happiness measurements. According to the hierarchical regression, demographic variables(sex, religion, economic levels), value types, and nature-relatedness explained 25%~36% of variance in happiness. Value was more related with psychological well-being than life satisfaction, positive affect, social well being, Korean happiness scale. This results emphasize the importance of healthy value(benevolence, self-direction) and provision of opportunities contact with nature to promote human happiness.

현대 정보사회는 교통수단의 발달과 더불어, 휴대용 기기의 급속적인 발전이 이루어지고 있다. 이에 초소형 발전기의 필요성이 부각되고 있다. 지금까지 개발된 초소형 발전기로는 태엽을 이용한 발전기, 기기의 회전력을 이용한 발전기, 태양열을 이용한 발전기 등이 있다. 이와 달러 본 논문에서는 평판형 압전소자를 이용한 초소형 발전기 개발에 관한 연구를 하고 있다. 평판형압전소자는 부피가 매우 작고 가벼우며. Impulse 형태의 작은 외력에도 큰 전압을 발생한다. 그러나 매우 작은 전류로 인해 낮은 전력이 발생한다. 이로인해 정확한 발전용량 측정이 어렵다. 이에 본 연구에서는 압전소자의 발전전기를 콘덴서에 충천, 이때의 정전용량을 측정하고 일정시간 동안 누적된 발전전기용량을 측정하였다. 이를 바탕으로 발전전기량 향상 방법을 개발하고 있다.

본 논문은 대규모 텍스트 데이터에서 이슈를 발굴할 때 사용되는 기존의 정보 네트워크 또는 지식 그래프 구축 방법의 한계점을 지적하고, 문장 단위로 정보 네트워크를 구축하는 새로운 방법에 대해서 제안한다. 먼저 문장을 구성하는 단어와 캐릭터수의 분포를 측정하며 의성어와 같은 노이즈를 제거하기 위한 역치값을 설정하였다. 다음으로 BERT 기반 언어모델을 이용하여 모든 문장을 벡터화하고, 코사인 유사도를 이용하여 두 문장벡터에 대한 유사성을 측정하였다. 오분류된 유사도 결과를 최소화하기 위하여 명사형 단어의 의미적 연관성을 비교하는 알고리즘을 개발하였다. 제안된 유사문장 비교 알고리즘의 결과를 검토해 보면, 두 문장은 서술되는 형태가 다르지만 동일한 주제와 내용을 다루고 있는 것을 확인할 수 있었다. 본 논문에서 제안하는 방법은 단어 단위 지식 그래프 해석의 어려움을 극복할 수 있는 새로운 방법이다. 향후 이슈 및 트랜드 분석과 같은 미래연구 분야에 적용하면, 데이터 기반으로 특정 주제에 대한 사회적 관심을 수렴하고, 수요를 반영한 정책적 제언을 도출하는데 기여할 수 있을 것이다

The purpose of this study is to discover unique personality traits which the children of 5 social status types using 10 clinical scales of Korea Children's personality test (KCPI-S) in order to define the characteristics of 5 social status types developed as the Korean type. For this purpose, two hypotheses were set and tested. The subjects of this study were 502 children who were 4, 5th and 6th grade elementary school boys and girls in A city. 5 social status types and gender of children were set as the independent variables each, and 10 clinical scales of Korea Children's personality test as the dependent variables. The research hypotheses were analyzed in turn by the multivariate analysis (MANOVA) and t-test. The results are as follows: First, the results of analyzing differences in 10 clinical scales in accordance with 5 social status types how the significant differences in all 9 clinical scales except for language development scale, and ${\eta}^2$ representing the explanatory power of the independent variables to dependent variables was found to be in the range of the lowest at 2% up to 10% for each scale. Second, the results of analysis of the gender difference show that in the case of the children with controversial and neglected children, the significant difference was appeared between boys and girls in 8-9 scales among the 10 clinical scales, but in the case of rest 3 social status types (average, popular, rejected children) the difference was appeared between boys and girls only in 2-3 scales. Depending on these results it seems that each of 5 social status types of the children has its own unique personality structure. It is necessary to attend to the fact that in the case of the children with controversial and neglected children, the average value of boys are significantly higher than that of the girls. There is a big possibility that the boys have more psychological problems that the girls. It is judged that in case of these two types the personal traits applying gender should be interpreted. Therefore, the follow-up study should conduct the exploratory research on the structure of the relationship between children's language development and sociality measure. Further, it is necessary to conduct the psychological comparison between genders in the children with controversial and neglected children, and to study the structure of their relationship with rest social status types by genders.

This study examined the differences of academic achievement by social status types through sociometry. This study analyzed 201 students in grade 6 in S elementary school. The social status is classified by 7 (popular, average, rejected, aggressive-rejected, submissive-rejected, neglected, controversial) with academic achievement of each type as dependent variables to figure out the relation between social status types and academic achievement. To classify 5 social status types, a sociometry program developed by Ahn, Ie-Hwan (2007) was used, 2 social status types was classified with experimental condition, and its dependent variable was the score by subjects in the mid-term exam of the 1st semester in 2011. The average values of humanities courses (Korean and social studies) and natural science courses (math and science) were compared by both sexes and 7 social status types. The reference group was average group. As a result, as to male students, N type had the highest score both in humanities courses and natural science courses while C type had the lowest score in both groups. As to female students, P, N, C types had the highest score in both groups with similar range while R type had the lowest score in both groups. This result demonstrates that the academic achievement of students had relatively high relevance with social status. and also, suggestion that how teachers can do to enhance the academic achievement of elementary school students.

The unexpected increase of violent crimes in Korea urges people to look for more dynamic explanations of criminal behavior other than sociological eugenics such as a struggle between social classes or assimilation to deviant social environment. In this study, criminal behavior is treated as personal matter according to the tradition of psychological theories of crime rather than sociological phenomenon. Furthermore, aggression is supposed to be one of the most basic dispositional characteristics of violent acts. Therefore, this study explored the relationship between aggression measured by BPAQ and criminality evaluated based on seriousness of criminal offenses. On the other hand, the cross-validity of BPAQ was also investigated since prevalence and expressive forms of violence is known to vary across cultures and even within a society. The variance analyses and causal modeling presented that BPAQ had satisfactory level of cross-validity and dispositional aggression measured by BPAQ might have causal effect on criminality of Korean offenders. Additionally, a theoretical internal structure of BPAQ had been confirmed to be reasonable by confirmatory factor analyses.
