Extending the findings of Rajagopal and Burnkrant (2009), this research examines the moderating role of consumers' goals (i.e., head category-relevant goal vs. modifier category-relevant goal) in the effects of two different interpretation strategies (i.e., relational interpretation vs. property interpretation) on product beliefs and attitudes toward hybrid products. In the current research, we make two predictions. First, we predict that both head category and modifier category beliefs will be higher under property interpretations than under relational interpretations in the modifier category-relevant goal priming conditions, whereas there will be no significant differences between each product category beliefs across the two interpretation conditions in the head category-relevant goal priming conditions. Second, we predict that attitudes toward hybrid products will be higher under property interpretations than under relational interpretations in the modifier category-relevant goal priming conditions, whereas there will be no significant differences between the attitudes toward hybrid products across the two interpretation conditions in the head category-relevant goal priming conditions. These predictions are tested and confirmed in two experiments. Finally, we discuss theoretical and practical implications of our findings and develop directions for future research.

In this study, we aim to converge a technology for analyzing the hydraulic circuit of a loading arm with an- other one for analyzing multi-body dynamics by utilizing analysis software SimulationX. Further, this study intends to overcome the limitations of the existing technology for analyzing a hydraulic circuit with a variation at the rotation center of the moving mass and the difficulty of incorporating the behavior in a gravity field. First, the specifications of the hydraulic circuit components were reflected in an analysis model to secure reliability. Hydraulic circuit modeling was then performed using a single analysis model with a verified reliability. Subsequently, the multi-body system (MBS) model of the loading arm was formed. Finally, the analysis model of the hydraulic circuit and the MBS model were converged to check if the circuit analysis result was exactly reflected in the MBS model. The convergence analysis model has development cost-saving effect because it is capable of predicting the dynamic behavior of an object without the prototype.

As the axle at the vehicle of railway has the important role for safe running, the strength, and impact-proof, safety factor, stress and deformation must be considered. There are the simulation models of 1 and 2 in this study. These models are investigated by performing the convergence technique through the design, the structural and fatigue analyses with CATIA and ANSYS. As the maximum deformation and equivalent stress of model A are lower than those of model B, model A has more durability than model B. The durability to prevent the damage can be investigated by applying the result of this study into the part design of the vehicle of rail road. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

상수관망 수리해석 기법은 절점의 사용량 및 누수량을 기지의 값으로 고려하여 총 수요량이 모두 공급될 수 있다고 가정하여 해석하는 수요기반해석(Demand Driven Analysis, DDA)과 사용량과 누수량은 절점 압력수두에 의해 달라질 수 있어, 공급가능량 및 누수량과 절점의 압력수두 모두를 미지수로 고려하여 해석하는 수압기반해석(Pressure Driven Analysis, PDA)으로 구분될 수 있다. 본 연구에서는 수압기반사용량 모의(Pressure Dependent Demand, PDD)와 수압기반누수량 모의(Pressure Dependent Leakage, PDL)기능이 모두 구현되고, 다양한 시나리오 분석이 가능한 소프트웨어(SW)인 K-NRisk를 개발하였다. K-NRisk는 2016년 7월에 공개된 상수관망 해석범용모형인 EPANET3 소스코드 기반으로 개량 개발되었으며, 기존 EPANET2와 비교하였을 경우 사용자 편의성 증대를 위한 입출력 기능 및 SW 활용도 제고를 위한 대표업무분석 기능이 신규 개발, 강화되었다. 개발된 SW를 관망정비 및 공급안정성 확보 목적을 위한 수리해석 시 적용하여 그 결과를 분석하였다. 적용결과 기존 수요기반해석이 가지고 있는 한계점을 보완하고, 실제업무 시 활용가능함을 확인하였다.

High pressure valve tester used in industrial fields precise measurement gives inconvenience in precise measurement due to manually regulated pressures. In order to improve this inconvenience, the high pressure valve tester was designed by using CATIA and structural analysis of the designed high pressure valve tester was conducted and water leaking, total deformation, strain and stress were obtained by applying ANSYS. These results will be provided to develop new concepts of high pressure valve tester as initial data.

In this study, the pleasant driving environment of the driver and passenger in the summer was investigated through the internal flow analysis of air due to the opening and closing of the car windows. The conditions on the entrance of the air conditioner with the opening and closing status of vehicle window were applied to the flow analysis by taking into consideration the actual driving environment. The automotive air conditioning outlet, the seat and the inside of car were modeled. As the air flow inside the car was analyzed, the air flow configuration and the temperature distribution were examined. In this analysis, the results were taken in consideration of only the effects of internal air and the opening and closing of window, assuming the interior of the vehicle as insulation. The analysis of each condition shows that these models maintain a pleasant environment. It is seen that this analysis result on the internal flow analysis according to the opening and closing of vehicle window can be applied by converging with the field of design.

In this study, the flow analyses by type of shock absorber orifice were carried out. A shock absorber is indispensable for the ride comfort that is important at the standard of a good car. As the analysis procedure, the actual speed of the shock absorber was set as the flow rate when the cylinder was advanced. And the flow analysis results on models A, B and C of shock absorber models were compared with each other. As the examination on the flow orifice in the vicinity of each model through the analysis of flow, the performance of shock absorber were recognized. On the whole, model A had the fastest flow rate and also had the largest flow rate. Model B had the slowest flow rate and the flow rate features of models B and C with the same number of orifices were similar. Through this study, it is possible to see which shock absorber orifice model facilitates the flow inside the cylinder and increases the ride comfort. It is seen that this analysis result on the flow analyses by type of shock absorber orifice can be applied by converging with the field of design.

This study compares and analyzes the results of structural analyses due to three constraint conditions on the emblem for car. The analysis results are studied by investigating the influence due to the column angle combined between the lower plate of amblem and the upper amblem. The combined with the amblem is parallel to the longitudinal axle of the amblem at the first case. The angle combined with the amblem is perpendicular to the lower plate at the second case. The angle combined with the amblem is perpendicular to the amblem at the third case as the last case. The amblem model for car can be thought to be optimized by investigating the fatigue life and the durability of amblem through the simulation of structural and fatigue analyses. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.
