  • Nuclear Power Plant consists of about 1.4 million facilities. and the design standards and design requirements for the continuos utilization and safety of facilities are complexly connected with the facilities. When a design change for facilities or design requirements is occurred at the time of construction or operation, there are a lot of facilities, design requirements, and design bases that are affected by the facilities or design bases being changed. The above design changes are so complex that the existing document-bases design change process is time-consuming and may also cause human error. In this study, we developed a design requirement taxonomy that can be applied to the data-centric design bases document that can improve it. To do this, we analyze the design elements from the highest level to the lowest level applied to the nuclear power plant, and classify the design elements according to the characteristics of the design elements.

  • Purpose - This study identifies relationships amongst repurchase intentions, brand equity, and preference by applying VMD of fashion retail stores. The results would help coffee shop owners and coffee makers in devising an appropriate strategy for successfully managing coffee shops. Research design, data, methodology - The VMD model of a coffee shop includes harmony, trend, and attractiveness, while brand equity encompasses brand awareness, perceived quality, and brand image. In this study, the VMD factors of coffee shops, brand equity, and brand preference, are shown as independent variables, while repurchase intention is shown as the dependent variable. The study aims to ascertain the extent of the influence configuration factors of a coffee shop have on brand equity, brand preference, and repurchase intention. Regression analysis was used to verify the mediating effects of brand preference on brand equity and repurchase intention. The measurement items were already deemed as reliable and valid in the previous study, but some modifications were made for the purposes of this study. Questionnaires were distributed to 550 consumers on a national scale, and 517 consumers amongst these were finally used as a sample for analysis using the SPSS 17.0 statistical program. Results - First, amongst the VMD configuration factors of a coffee shop, trend, and attractiveness have a positive impact on brand equity (brand awareness, perceived quality, and brand image). Second, brand equity has a positive effect on brand preference. Third, brand preference has a positive effect on repurchase intention. Fourth, brand preference plays the role of a mediator in measuring the impact of brand awareness and brand image on customers' repurchase intentions. Conclusions - The theoretical implications can be summarized as follows. First, this study proposes a theoretical basis that can be adapted to the VMD configuration factors of a coffee shop by identifying the relationship between brand equity and coffee shops. This study applies the VMD factors to the coffee shops and presents a new research model by examining the relationships amongst VMD components of coffee shops: brand equity, brand preference, and repurchase intention. Second, it clearly establishes the relationship between brand equity and brand preference by identifying the mediating effects of brand preference, given that brand equity has a positive impact on repurchase intention. The practical implications are as follows. First, development of brand equity and management can be important components for coffee shops in determining that the VMD configuration factors of coffee shops have an impact on brand equity. Second, amongst the VMD configuration factors, attractiveness and trend have a positive influence on choosing coffee shops, therefore store atmosphere should be attractively designed, while the menu and interiors should complement each other and be reviewed periodically to conform to the latest trend. Third, VMD configuration factors that are confirmed are not easily changed. Fourth, large franchises and foreign companies have strengths in scale, locations, and brand. Fifth, the different ways of campaigning should be compared to those of large franchises and foreign companies in order to increase brand equity using VMD configuration factors.

  • The main objective of this study is systemization of the technique of ROC quantification and optimization of baseline design by applying CE principle to the acquisition process of a weapon system. QFD and TOA techniques can be employed to a good working example of the conceptual design of a future main battle tank. In this paper, Product Planning Phase, the first phase of four QFD phases, is deployed in terms of eight steps including customer requirements and final product control characteristics. TOA is carried out considering only combat weight. In order to perform combat weight analysis and performance TOA, Preliminary Configuration Synthesis Methodology is used. Preliminary Configuration Synthesis Methodology employs the method of least squares and described linear equations of weight interrelation equation for each component of tank. As a result of QFD based upon the ROC, it was cleared that armor piercing power, main armament, type of ammunition, cruising range, combat weight, armor protection, power loading, threat detection and cost are primary factors influencing design and that combat weight is the most dominant one. The results of TOA based on the combat weight constraint show that 5100 lb reduction was required to satisfy the ROC. The baseline design of a future main battle tank is illustrated with assumption that all phases of QFD are employed to development and production process of subsystems, components, and parts of main battle tank. TOA is applied in iterative process between initial baseline design and ROC. The detailed design of each component is illustrated for a future main battle tank.

  • Modern embedded system employs a hybrid architecture which contains a general micro processor and reconfigurable devices such as FPGAS to retain flexibility and to meet timing constraints. It is a hard and important problem for embedded system designers to explore and find a right system configuration, which is known as design space exploration (DSE). With DES, it is possible to predict a final system configuration during the design phase before physical implementation. In this paper, we implement a timing analysis simulator for a DSE on a hybrid embedded system. The simulator, integrating exiting timing analysis tools for hardware and software, is designed by extending Y-chart approach, which allows quantitative performance analysis by varying design parameters. This timing analysis simulator is expected to reduce design time and costs and be used as a core module of a DSE for a hybrid embedded system.

  • Design variables for suspension systems cannot always be realized in the actual suspension systems due to tolerances in manufacturing and assembly processes. In order to deal with these tolerances, design variables associated with kinematic configuration and compliance characteristics of suspensions are treated as random variables. The reliability of a design target with respect to a design variable is defined as the probability that the design target is in the acceptable design range for all possible values of the design variable. To compute reliability, the limit state, which is the boundary between the acceptable and unacceptable design, is expressed mathematically by a limit state function with value greater than 0 for acceptable design, and less than 0 for unacceptable design. Through reliability analysis, the acceptable range of design variables that satisfy a reliability target is specified. Furthermore, through sensitivity analysis, a general procedure for optimization of the design target with respect to the design variables has been established.

  • In this paper, we consider the effects on the bandpass filter characteristics due to the phase variation of the inverters with frequency, which introduces the deviations of the bandpass filter characteristics from the design goals. In order to resolve these kinds of problems, we proposed novel inverter configurations. And we derived the inverter formulas for the proposed inverter configuration. By employing the proposed inverter configuration and the derived formulas, bandpass filters are designed and simulated. In order to show the validity of the proposed design method, the simulation characteristics are compared with design results by conventional design procedures. Compared results show the compensation of the deviations of bandpass filter characteristics without any optimization or iterative design procedures and additional calculation efforts.
