This study researches the effectiveness of interactive TV advertising focusing on the factors of audience involvement and interaction. The study began with the effective measurement of interactive television advertisements. Interactive television advertisements have different concepts than existing television advertisements. This study mainly focuses on the characteristics of audience interaction and experiments based on the data of 78 persons for measurement. In the experiments, the characteristics were categorized according to search time, specifically the number of searched pages about interactive television advertisement. Hypothesis 1 reveals that the interaction of the audience increases when the advertising attitude, brand attitude, and purchase intentions also increase. Hypothesis 2 finds that the involvement of the audience increases when the advertising attitude, brand attitude, and purchase intentions also increase. By studying these consumer characteristics and behavior, a new method of effective measurement for interactive television advertisement is uncovered. The new method includes not only existing measurement elements of television advertisement which include attitude about advertising and brand, and customer purpose, but also the features of interactive television advertisement like customer search time. According to this research on interactive television advertisement, the interaction with and involvement of the audience are highly influential variables.

This study examines the effects of teacher's emotional intelligence on teacher-child interaction through the sequential mediation effects of efficacy belief about play and professional recognition. Participants were 268 teachers working at kindergartens in Gyeonggi area. Data were analyzed by descriptive statistic, Pearson's product-moment correlation, and the structural equation model using the SPSS 21.0 and Mplus 6.12 program. The main findings of this study are as follows: First, in regards to the relationship between emotional intelligence and teacher-child interaction, a single mediation effect of efficacy belief about play is significant. But there is no significant mediation effect of the professional recognition. Second, in regards to the pathway from emotional intelligence to teacher-child interaction, the professional recognition precedent mediation model is statistically significant, but efficacy belief about the play precedent mediation model is not significant. Based on the results, a concluding discussion was made regarding methods toward enhancing interaction between teacher and child.

In this paper, a new iterative method for solving vehicle-bridge interaction problems is proposed. Iterative methods have advantages over the non-iterative methods in that it is not necessary to update the system matrix for a given wheel location, and the method can be applied for a new type of car or bridge with few or no modifications. In the proposed method, the necessity of system matrices update is eliminated using the equivalent interaction force acting on the bridge, which is obtained iteratively. Ballast stiffness is included in the interaction forces and the geometric compatibility at the contact points are used as convergence criteria. The bridge is considered as an elastic Bernoulli-Euler beam with surface irregularity and ballast stiffness. The moving vehicle is modeled as a multi-axle mass-spring-damper system having many degrees of freedom depending on the number of axles. The pitching effect, which is the interaction effect between the rear and front wheels when a vehicle begins to enter or leave the bridge, is also considered in the formulation including extended ground boundaries having surface irregularity and ballast stiffness. The applicability of the proposed method is illustrated in the numerical studies.

Purpose This study investigates that the routes of psychological ownership in Fanpage and the effect of psycholoigical ownership on customer loyalty based on psychological ownership theory. Fans are customers who clicked 'Like' on the fan page. These fans have a lot of friends on Facebook, so the word-of-mouth is more effective than other online communities. Therefore, it is necessary for fans to have psychological ownership, actively responding to the fan pages, and recommending them to friends. However, previous social network service studies have overlooked the importance of psychological ownership. In this study, we examine what factors can increase psychological ownership and show that customer loyalty can be enhanced through psychological ownership. Design/methodology/approach This study was designed to investigate the structural relationship between Fanpage Familiarity, Interaction(Customer-Brand interaction and Customer-customer interaction), Psychological Ownerhisp, and Customer Loyalty. Structural equation modeling with SmartPLS2.0 was used to analyze the relationships in the research model. Findings The results showed that Fanpage Familiarity and Customer-customer interaction is positively related with Psychological Ownership. However, Customer-Brand interaction did not influence Psychological Ownership. Psychological Ownership has a positive impact on Intention to Continue Using Fanpage and Recommend.

The aim of this paper is to investigate how the soil-structure interaction affects sloshing response of the elevated tanks. For this purpose, the elevated tanks with two different types of supporting systems which are built on six different soil profiles are analyzed for both embedded and surface foundation cases. Thus, considering these six different profiles described in well-known earthquake codes as supporting medium, a series of transient analysis have been performed to assess the effect of both fluid sloshing and soil-structure interaction (SSI). Fluid-Elevated Tank-Soil/Foundation systems are modeled with the finite element (FE) technique. In these models fluid-structure interaction is taken into account by implementing Lagrangian fluid FE approximation into the general purpose structural analysis computer code ANSYS. A 3-D FE model with viscous boundary is used in the analyses of elevated tanks-soil/foundation interaction. Formed models are analyzed for embedment and no embedment cases. Finally results from analyses showed that the soil-structure interaction and the structural properties of supporting system for the elevated tanks affected the sloshing response of the fluid inside the vessel.

This paper focuses on how cognitive and emotional structures affect humans during long-term interaction. We design an interaction with a turn-based game, the Chopstick Game, in which two agents play with numbers using their fingers. While a human and a robot agent alternate turn, the human user applies herself to play the game and to learn new winning skills from the robot agent. Conventional valence and arousal space is applied to design emotional interaction. For the robotic system, we implement finger gesture recognition and emotional behaviors that are designed for three-dimensional virtual robot. In the experimental tests, the properness of the proposed schemes is verified and the effect of the emotional interaction is discussed.

SLD 조건은 직경이 50㎛ 이상인 과냉각대형액적의 분포가 지배적인 결빙 환경을 뜻한다. SLD 조건에서는 액적의 큰 크기로 인해 wall-droplet interaction, deformation 등의 물리적 현상이 착빙 과정에 중요한 영향을 미친다. 그에 따라 SLD 효과를 수치적으로 모사하기 위한 다양한 연구가 수행되었고, 부착률을 수정하는 후처리 기법을 통해 wall-droplet interaction 현상을 고려하는 방법이 제안되었다. 그러나 이 방법은 액적이 충돌하는 벽면 특성을 제대로 고려하지 않는 반경험식(Wright Model)을 사용하기 때문에 착빙 영역에서 여전히 부착률과 부착 한계를 과대 예측한다. 이 문제를 해결하기 위해 본 연구에서는 착빙 영역을 세 개의 영역으로 구분하였다. 그리고 벽면 특성을 고려하는 Bai and Gosman rebound 모델을 바탕으로 개발한, 새로운 wall-droplet interaction 모델을 후처리 기법에 도입했다. 그리고 액적의 항력계수를 증가시키는 deformation 현상을 반영하기 위해 3가지 deformation 모델을 비교·분석하여 가장 적합한 모델을 선정했다. 앞의 내용을 바탕으로 개발한 SLD 결빙 예측 코드를 검증하기 위해 실험 데이터를 활용하여 해석을 수행했다. 그 결과 수정된 후처리 기법은 착빙 영역에서 rebound 현상에 의한 부착률 감소를 더욱 크게 예측하였고 부착 한계와 부착률 크기를 예측하는 데 있어 향상된 정확성을 보여줬다. 그리고 deformation에 의한 항력계수의 증가를 가장 크게 결정하는 Wiegand model이 실험과 가장 유사한 것을 확인할 수 있었다.

A semi-stochastic process model of reliability was established for hyperbolic cooling towers subjected to combined loadings of wind force, self-weight, temperature loading. Effect of the soil-structure interaction on reliability was evaluated. By involving the gust factor, an equivalent static scheme was employed to convert the dynamic model to static model. The TR combination rule was used to consider relations between load responses. An analysis example was made on the 90M cooling tower of Maoming, Guangdong of China. Numerical results show that the design not including interaction turns to be conservative.
