There have been various approaches for efficiency improvement of a Darrieus tidal stream turbine after it was introduced as an alternative of horizontal axis turbines. Among the approaches, the researches on the interaction effect of dual configuration were conducted. In this study, a dual Darrieus turbine with a coupling mechanism was proposed for investigating the interaction effect. Also, the effect of bi-directional tidal stream was analyzed with prototype fabrication, apparatus set-up and experiment conduction in indoor and offshore facilities. As the results of the experiments, the dual turbine in case of counter-rotation and inflow between the turbines improved efficiencies by 9.5% and 11.31%, respectively, as compared to the single turbine. Also, the dual turbine in case of the inflow improved efficiencies by 9.4% and 16.62%, respectively, as compared to that in case of outflow between the turbines which represented the case of 180 degrees change of flow direction after slack water. Therefore, the proposed dual turbine showed the advantage in terms of the efficiency as compared to the single turbine and the effect level of the slack water on the performance of the dual turbine was investigated.

Objective: This study focused on the relationships between emotionality, social competence and play behavior in a sample of 218 4- to 5-year olds attending daycare centers. Methods: All variables were measured by the daycare teachers of the surveyed children. The data were analyzed using Simple Regression and Multiple Regression through SPSS Win 25.0. Results: First, preschoolers' positive emotionality had a negative effect on their play disruption and play disconnection and a positive effect on play interaction. On the other hand, their negative emotionality had a positive effect on play disruption and play disconnection and a negative effect on play interaction. Second, their positive emotionality had a positive influence on social competence and their negative emotionality had a negative influence. Finally, the effect of their positive emotionality on play disruption was partially mediated, and their play disconnection and play interaction was totally mediated by social competence. On the other hand, the effect of preschoolers' negative emotionality on play disruption and play disconnection was totally mediated, and their play interaction was partially mediated by social competence. Conclusion/Implications: The results of this study imply that we need to help preschoolers promote emotionality and social competence together to change their play behavior positively.

Purpose: This study identified the effects of the three types of consumer interactions on the utilitarian and hedonic values experienced by community members, their degree of participation, and brand loyalty. In addition, the mediating effect of virtual interactivity between the interactions that occur within the online brand community and the value experienced by community members was also identified. Research design, data and methodology: An online survey was distributed, and the data gathered was analyzed using structural equations modeling. Results: Test results showed that product-information interaction has a positive effect on utilitarian value and interpersonal interaction has a positive effect on hedonic value. Human-computer interaction was found to have a negative effect on hedonic value and no significant effect on utilitarian value. Furthermore, it was revealed that among the three types of interactions, virtual interactivity had a mediating effect only in the relationship between human-computer interaction and hedonic value. Moreover, utilitarian values experienced by community members affected their level of participation which ultimately enhances brand loyalty. Hedonic value did not affect their level of participation within the online brand community. Conclusions: When marketers establish online brand community strategies, they must place elements that can directly help the use of brands and products.

Purpose: The present study is a descriptive cross-sectional study of cause-and-effect relationship, which used the $7^{th}$ year data of the Panel Study on Korean Children, to investigate the effects of parenting stress, depression, and family interactions of the parents of early school-age children on children's subjective happiness. Methods: The present study included data of 1419 pairs of parents who participated in the mother and father survey of the Panel Study on Korean Children. The effects of parenting stress, depression, and parental family interactions on children's subjective happiness were analyzed as actor and partner effects using path analysis. Results: Parenting stress had an actor effect on depression; maternal parenting stress (${\beta}=-.21$, p<.001) and depression (${\beta}=-.30$, p<.001) had an actor effect on maternal family interaction; and paternal parenting stress (${\beta}=-.18$, p<.001) and depression (${\beta}=-.17$, p<.001) had a partner effect on maternal family interaction. Paternal parenting stress was found to have an actor effect on paternal family interaction (${\beta}=-.30$, p<.001), and parental depression was found to have actor effect (${\beta}=-.23$, p<.001) and maternal depression had a partner effect on paternal family interactions (${\beta}=-.22$, p<.001). Children's subjective happiness was found to have a statistically significant relationship with maternal family interaction (${\beta}=.40$, p<.001). Conclusion: The significance of the study is in its provision of basic data for adjusting parents' family interactions that are closely related to the growth and development of children by confirming the effect of parents' parenting stress, depression, and family interaction on children's subjective happiness.

수직 자기기록 매체로 알려진 CoPt 자성막을 전기도금법으로 제작하여 자기상호작용이 활성화 부피와 면적에 미치는 영향을 조사하였다. 모든 시료의 상호작용 기구는 쌍극자 상호작용이었으며, 낮은 전류밀도에서 제작한 시료일수록 두께가 두꺼울수록 상호작용 세기가 증가하였다. 한편 활성화 부피는 낮은 전류밀도에서 제작한 시료가 더 컸으나 두께에 따른 증감현상은 뚜렷하지 않았다. 그러나 활성화 면적은 상호작용의 세기가 강할수록 전류밀도가 낮을수록 감소하는 경향을 보였다.

The hydrodynamic interaction forces and moments induced by the vicinity of bank on a passing vessel are known as wall effects. In this paper, the characteristics of interaction acting on a passing vessel in the proximity of a semi-circle bank wall are described and illustrated, and the effects of ship velocity, water depth and the lateral distance between vessel and semi-circle bank wall are discussed. For spacing between ship and semi-circle bank wall (SP) less than about 0.2 L and depth to ship's draft ratio (h/d) less than around 2.0, the ship-bank interaction effects increase steeply as h/d decreases. However, for spacing between ship and semi-circle bank wall (SP) more than about 0.3 L, the ship-bank interaction effects increase slowly as h/d decreases, regardless of the water depth. Also, for spacing between ship and semi-circle bank wall (SP) less than about 0.2 L, the hydrodynamic interaction effects acting on large vessel increase largely as ship velocity increases. In the meantime, for spacing between ship and semi-circle bank wall ($S_P$) more than 0.3 L, the interaction effects increase slowly as ship velocity increases.

일반적으로 강콘크리트 합성형교는 불완전합성에 대한 해석의 복잡함 때문에 강재와 콘크리트 계면에서의 상대변위가 발생하지 않는 완전합성형으로 설계된다. 그러나, 이러한 설계는 기존 강합성형 의 거동을 평가하는 경우 실제 구조물의 내하력과 내구성을 정확하게 도출하지 못하게 된다. 이러한 경우에는 불완전합성이론을 이용하여 구조물의 거동을 정확히 반영해야 한다. 본 연구에서는 집중하중을 받는 단순합성형교에 대하여 처짐 거동을 고려한 불완전합성곡률의 변화양상을 확인하기 위하여 유한요소해석 모델을 이용하여 전단연결재의 배치간격과 배치열수 그리고 콘크리트 탄성계수를 매개변수로 선택하여 해석을 수행하였다. 본 연구의 결과로서 합성형의 처짐이 증가할수록 불완전합성 정도가 증가함을 알 수 있었으며, 콘크리트 슬래브에서 균열이 발생으로 인한 강성 및 강도의 감소가 합성정도에 큰 영향을 미치는 것을 알 수 있었다.

Dynamic response of Pile Supported Structures is highly depended on Soil Pile Structure Interaction. In this paper, by comparison of experimental and numerical dynamic responses of a prototype jacket offshore platform for both hinge based and pile supported boundary conditions, effect of soil-pile-structure interaction on dynamic characteristics of this platform is studied. Jacket and deck of a prototype platform is installed on a hinge-based case first and then platform is installed on eight skirt piles embedded on continuum monolayer sand. Dynamic characteristics of platform in term of natural frequencies, mode shapes and modal damping are compared for both cases. Effects of adding and removing vertical bracing members in top bay of jacket on dynamic characteristics of platform for both boundary conditions are also studied. Numerical simulation of responses for the studied platform is also performed for both mentioned cases using capability of ABAQUS and SACS software. The 3D model using ABAQUS software is created using solid elements for soil and beam elements for jacket, deck and pile members. Mohr-Coulomb failure criterion and pile-soil interface element are used for considering nonlinear pile soil structure interaction. Simplified modeling of soil-pile-structure interaction effect is also studied using SACS software. It is observed that dynamic characteristics of the system changes significantly due to soil-pile-structure interaction. Meanwhile, both of complex and simplified (ABAQUS and SACS, respectively) models can predict this effect accurately for such platforms subjected to dynamic loading in small range of deformation.
