하천유량측정은 불가피하게 사교형태의 교량에서 측정을 해야하는 경우가 적지 않다. 이러한 교량에서의 유량측정은 수위-단면적이 과대산정되어 유량 역시 크게 산정되므로 이에 대한 보정을 필요로 한다. 본 연구에서는 왕숙천에 위치한 퇴계원 수위관측소 하류 400m 위치에서의 도섭법을 통한 횡단면 측선각도 변화에 따른 유량차의 비교와 오산천에 위치한 약 $45^{\circ}$ 사교(탑동대교)의 탑동 수위관측소 위치의 교량법을 이용한 유량측정 성과, 한탄강에 위치한 약 $15^{\circ}$ 사교(한탄대교)의 전곡 수위관측소 상류 1km에 위치한 한탄대교에서의 교량법 측정 성과에 따른 유량차를 비교 분석하였다. 한강유역 왕숙천, 오산천, 한탄강에 위치한 퇴계원 지점, 탑동 지점, 전곡 지점에서 실시간 수위에 따른 유속을 측정하였으며, 퇴계원 지점에서는 횡단면에 직각인 측선을 기준 값으로 제시하고, 횡단방향각의 정도를 $10^{\circ}$, $30^{\circ}$, $50^{\circ}$으로 늘려 산정을 하였고, 탑동과 전곡 지점에서는 사교에서의 횡단각을 측정하여 사교의 각을 산정한 후 보정 전 후의 유량 값을 비교 분석하였다. 측정에 사용된 기기는 Price AA 유속계이고, 측정방법은 도섭법과 교량법을 적용하였다. 그 결과 직각인 측선에서 측정한 유량보다 사교형태에서 측정한 유량이 크게 산정되었다. 각 지점의 보정전 후 유량비는 탑동 지점 약 41.42%, 전곡 지점 약 3.53%로 산정되어 $15^{\circ}$ 사교의 전곡 지점에 비해 $45^{\circ}$ 사교의 탑동 지점의 보정전 후 유량차이가 크게 나타남에 따라 각이 클수록 유량 역시 과대하게 산정됨을 알 수 있었다. 따라서 유량측정을 실시할 경우 유량의 흐름방향을 기준으로 직각의 유량측정을 실시하여 유량을 산정하되 부득이한 경우로 사교에서의 측정이 이루어졌을시 흐름 방향을 기준으로 각도를 측정하여 크게 나타나는 수위-단면적에 각보정하여 유량을 산정함이 오차를 줄일 수 있으며, 신뢰성 있는 유량자료 생산의 방법이라 할 수 있겠다.

There have been studies about dog’s personality and behavior, which is helpful to breed dogs as guide or companion. In this study, a questionnaire was developed using 54 Jindo dogs, which considered ten items about aggressiveness and sociability. The scores were analyzed by principle component analysis (PCA), after accounting for four variables: age, gender, growing place, and coat-colors. Our results from the PCA indicated three principle components, which classified ‘aggressiveness’, ‘sociability’ and unknown factor. The four variables did not significantly affect aggressiveness(P>0.05). However, there was a relationship between coat-color and sociability, i.e., the Jindo dogs with fawn color were more sociable than the white ones(P<0.1).

The purpose of this study is to analyze the effects of undergraduates' smart phone addiction on their development of sociality. According to the results of positive analysis, if smart phone addiction gets more serious, sociality becomes lower. More concretely, smart phone addiction consists of its subareas: difficulties in daily living, pursuing experience in the virtual world, withdrawal, and tolerance. Sociality has its subareas as confidence, sociability, and interpersonal relationship. If difficulties in daily living and tolerance become increased, confidence gets lower. In addition, as pursuing experience in the virtual world and withdrawal become increased, sociability gets lower. Regarding the dispositions of smart phone addiction in groups subdivided by sex, men are more apt to be addicted than women. Recently, smart phone use has been tremendously increased, and issues regarding addiction to it have been raised as problems in society. Therefore, it will be needed to discuss solutions for more reasonable use in society in order to prevent smart phone addiction.

This study is identifying a social standing on adolescents' social network in offline and how the social standing influence to online social activity. For the purpose, we explore two research questions. First, How the adolescents' social standing present in their offline social network? Second, How the adolescents' social standing influence to online social activity? Using data, we first visualized 5 social network of adolescents, and deducted each ego networks and global network. Also we investigated causality between social standing and social activities. The result showed adolescents' social tie and social gregariousness influence to social activity width and depth in ego network. Based on these findings, we discussed some implications, limitations, and future direction.

Firstly the problems of existing foreign code concerning wheel load distribution factor for skew box girder bridges have been examined, and the main parameters which have effects on wheel load distribution factors are evaluated in this study. Further finite element analyses on various skew steel box girder bridges are carried out. Based on the analysis results, formulas to determine wheel load distribution factors are proposed using multiple regression analysis. It is found when using the proposed formulas in this study weak points of existing specifications could be improved and also time spent at structural analysis should be saved a lot, so that the validity and practicality could be verified.

This study investigated the influence of children's emotional expression and sociability, and their mothers' communication pattern on their prosocial behavior. The participants were 65 preschool children aged between 5 and 6, and their mothers. Each child-mother dyad was observed for 30 minutes in a lab setting, which was designed to evaluate the child's socioemotional competence and the mother's socialization behavior. Videotaped data were analyzed by two coders for aspects of sharing behavior, the expression of happiness, sadness, anger, anxiety, and sociability for children, and mothers' communication strategies. Results showed that children's anger and anxiety expression were the most significant predictors for their prosocial behavior. Mothers' punitive communication pattern negatively affected children's prosocial behavior. However, when compared to the children's emotional expression, its' accountability were not significant. The influence of negative emotions, and its' adverse role in interpersonal interactions are discussed.

The capacity of bearings installed at abutments and piers for continuous bridges is usually determined by the magnitude of the maximum vertical reaction at each support and the capacity of bearings placed at piers is higher than that at abutments. In this study, the possibility of the improved seismic performance of base-isolated continuous skew bridges was investigated by analysing the variation of the seismic behavior of them according to three arrangements of bearings. Based on the conventional arrangement of bearings(Case A), three arrangements of bearings such as Case A, Case B and Case C were selected considering the variation of the horizontal stiffness of the lead rubber bearing(LRB) installed at the pier. The seismic behavior of the total 36 skew bridges was investigated by conducting the response spectrum analysis using the hybrid response spectrum considered the effect of LRB's damping. Results of analyses show that a more desirable seismic behavior of base-isolated continuous skew bridges can be obtained by reducing the magnitude of the horizontal stiffness of LRB placed at the pier to similar to or less than that of LRB installed at abutments. The variation of LRB's stiffness at the pier brings about period elongation and the change of mode shapes of base-isolated skew bridges and results in the reduction of the total base shear, the maximum base shear at the pier and the girder stresses. Although positive effects on the seismic behavior of base-isolated skew bridges caused by the change of arrangement of bearings decreased slighty with an increase in the flexibility of the substructure, the proposed arrangements of bearings bring about the improved seismic performance of base-isolated continuous skew plate girder bridges with less than 10m height of piers.
