This study aims to examine the effects of on premium convergence products buying behavior. This paper analyzed the positive attitude formation using the basic and extended TAM and also revealed how the positive premium convergence product attitude relate to relationship purchasing intention and word of mouth intention. The samples of 562 consumer indicate that the antecedents are consist of four dimension(perceived usefulness, perceived ease of use, social value) and attitude is developed into buying intention and word of mouth intention. We have reached the following conclusion about the antecedents and outcomes factors of customer attitude for the launch of premium convergence product. First, perceived usefulness, perceived delight, and social value had a positive effect on customer attitude but perceived ease of use did not. Second, we found that customer attitude had a positive effect on purchase intention and word-of mouth intention. Finally, interaction effect of perceived usefulness/perceived delight and social value had a positive effect on customer attitude. Our findings suggested that adoptian and diffusion of premium convergence product is influenced by several behavior factors. Managerially, our result emphasize that premium convergence products must satisfy not only the perceived usefulness/delight but also social value that consumers are seeking in order to be successful in the market. The theoretical and practical implications of these findings are discussed as well.

This paper presents how redevelopment of the boundary layer in a backward-facing step flow is affected by boundary conditions imposed on velocity at the inlet, top and exit of the flow. A two-dimensional, laminar, incompressible flow over a backward-facing step with an open top boundary has been computed by using numerical methods of second-order time and spatial accuracy and a fractional-step method that guarantees a divergence-free velocity field at all time. The inlet velocity profile above the step is of Blasius type. Along the top boundary, shear-tree and Dirichlet conditions on the streamwise velocity were considered and at the exit fully-developed and convective boundary conditions were examined. (The vertical velocity at all boundaries were assumed to be zero explicitly or implicitly.) From the computed flow fields, the reattachment on the bottom side of shear layer separated from the tip of the step and succeeding redevelopment of the boundary layer were investigated.

In order to investigate the operating characteristics of a supersonic steam ejector, the axisymmetric, compressible, Reynolds-averaged, Navier-Stokes computations are performed using a finite volume method. The secondary and back pressures of the ejector system with a second throat are changed to investigate their effects on the suction mass flow. Three operation modes of the steam ejector system, the critical mode, subcritical mode and back flow mode, are discussed to predict the critical suction mass flow. The present computations are validated with some experimental results. The secondary and back pressures of the supersonic steam ejector significantly affect the critical suction mass flow. The present computations predict the experimented critical mass flow with fairly good accuracy. A good correlation is obtained for the critical suction mass flow. The present results show that provided the primary nozzle configuration and secondary pressure are known, we can predict the critical mass flow with good accuracy.

In this paper, characteristics of the motions of a human arm are investigated experimentally. When the conditions of the target point are restricted, human adjusts its trajectory and velocity pattern of the arm to fit the conditions skillfully. The purpose of this work is to examine the characteristics of the trajectory, velocity pattern, and the size of the duration in the following cases. First, we examine the case of point-to-point motion. The results are consistent with the minimum jerk theory. However, individual differences in the length of the duration can be observed in the experiment. Second, we examine the case which requires accuracy of positioning at the target point. It is found that the velocity pattern differs from the bell shaped pattern explained by the minimum jerk theory, and has its peak in the first half of the duration. When higher accuracy of the positioning is required, learning effects can be observed. Finally, to examine the case which requires constraint of the arm posture at the target point, we conduct experiments of a human trying to grasp a cup. It is considered that this motion consists of two steps : one is the positioning motion of the person in order to start the grasping motion, the other is the grasping motion of the human's hand approaching toward the cup and grasping it. In addition, two representative velocity patterns are observed : one is the similar velocity pattern explained in the above experiment, the other is the velocity pattern which has its relative maximum in the latter half of the duration.

The purpose of this study was to examine the mediating effect of the adult attachment in the relationship between the family of origin functioning and fear of intimacy. Data were collected through a questionnaire from 557 university students in the Jeollabuk-do of South Korea. The collected data were analyzed by basic descriptive statistics, Pearson's correlations and multiple regression analysis. Baron and Kenny's method was used and examined, and the Sobel test was performed to determine the mediating model's significance. It was adapted to SPSS ver. 18.0 for Windows. The major findings were as follows: first, the functioning of family-of-origin was negatively related to the fear of intimacy. In addition, younger students and students with less past dating experience were more likely to fear of intimacy. Second, fear of intimacy was influenced by the family-of-origin through the intermediate effect of attachment avoidance and attachment anxiety. Attachment avoidance and attachment anxiety had partial mediating effects on the relationship between family-of-origin functioning and the fear of intimacy. That is, family-of-origin functioning was shown to have not only a direct effect, but also an indirect effect through attachment avoidance and attachment anxiety, on the fear of intimacy. The results of this study suggest that the importance of family-of-origin functioning in order to improve Korean college students' intimacy abilities.

The purpose of this study is to examine the mediating effects of teachers' psychological well-being between teachers' attachment history and child-teacher relationships. The participants of this survey were 342 teachers from 41 day care centers and 11 kindergartens in four metropolitan cities and five provinces in Korea. The collected data were analysed through frequency and percentage calculation, Pearson's correlations, and the mediation methods suggested by Baron & Kenny(1986) were calculated by using SPSS 21.0. The findings are as follows. First, the percentage points of the attachment history of early childhood, the teachers' psychological well-being and the child-teacher relationship were higher than the average. Also, all the variables had correlations. Second, the teachers' psychological well-being partly mediated the relations between attachment history and child-teacher relationships. These results imply that teachers' psychological well-being is needed for positive child-teacher relationships, and can provide policy implications for teachers' psychological well-being in order to improve the quality of child-teacher relationships.

The purpose of this study is ; 1) to identify the overall levels of family problem and stress perceived by urban homemakers, 2) to investigate the relations between them. For the purpose of this study, the samples were chosen among 369 homemakers living in Seoul. These data were analyzed by Frequency, mean, t-test, F-test, Duncan's Multiple Rang test and pearson's correlation. The significant results are as follows : 1) urban homemakers perceive 'economic problem' as the highest level, 'children problem' as the second one and 'health problem' as the lowest one in family life problem. There is significant difference in family problem perception according to education level, husband's job, children's numbers, and living level. 2) There is not sigificant difference in stress level according to independence variables. 3) There are positive correlations between the family problem perception and stress level of urban homemakers. In conclusion, we come to know every field of family life effects homemakers as stressors. According, it is necessary for us to understand and prevent family life problem in order to release stress perceived by homemakers.
