The surfaces of prototypes become rough due to the stair-stepping which is the inevitable phenomenon in the Rapid Prototypes are not used only for the verification of feature. The grinding, coating, or the composition of them is a main operation in post-processing in which lots of costs and long build time are needed. The solution is proposed to increase the efficiency of rapid prototyping by minimizing or removing the composition of them is a main operation in post-processing in which lots of costs and long build time are needed. the solution is proposed to increase the efficiency of rapid prototyping by minimizing or removing the regions for post-processing. the factors to cause the surface roughness and their effects are analyzed through the experiments. Software modules are developed to predict the surface roughness of each face in the prototyping with the result. An experimental compensation method is developed to apply the modules to various RP equipments, materials and build styles. The build direction is searched with use of genetic algorithm to maximize the total areas of the surface of which roughness is better than the user-defined value.

Brand orientation is a relatively new paradigm in marketing which was first introduced in the 1990s. Since then, an accumulating body of research has addressed the strategic importance of brand orientation. Although there is a growing body of literature on brand orientation, there have been no empirical studies examining the mediation effect of brand orientation on market orientation-performance relationship to date. Moreover, most studies on brand orientation have been carried out in the context of large enterprises. Hence, the aim of this research is to extend the literature and address market orientation, brand orientation, and firm performance against the backdrop of Korean SMEs. The authors empirically investigate the impact of market/brand orientation on organizational performance and the mediating role of brand orientation. They utilize 178 usable responses to test the four research hypotheses. The hypothesized model predicts that there is a positive association among market orientation, brand orientation, and firm performance. It is also expected that brand orientation mediates the relationship between market orientation and organizational performance. The statistical results based on PLS analysis confirm our prediction among the constructs in the research model. The empirical evidence provides significant theoretical and managerial implications for brand orientation among SMEs. The first theoretical implication is that we provide empirical evidence regarding the important role of brand orientation in explaining the multi-trait perspectives of strategic orientation. The second theoretical implication is that the concept of brand orientation can be empirically validated in the context of SMEs. In terms of managerial implications, managers of SMEs should attempt to build a brand-oriented corporate culture or mindset that places brand values and brand norms as the top priority among their company's tasks. In addition, managers should recognize that brand orientation is critical for SMEs as well as large enterprises. In the last section, the authors address limitations of the study and provide directions for further research.

In any rapid prototyping process, the layer by layer building process introduces an area error between the staircase and the surface line specified by the computer-aided design model. This affects the dimensional accuracy as well as the surface finish for different part build orientations. This paper describes a methodology for computing the area error for any orientation of the part built by the fused deposition modelling system. This technique can be applied to determine the best build orientation of the part, based on the minimum area error. This technique is verified by comparing the results with the experimental measurements of the area error of the parts built at different orientations.

In the context of economic integration and fierce competition, organizations are very concerned about customer orientation so as to build close relationships and ensure customer satisfaction and improve customer loyalty. In company strategy, customer relationship orientation is critical. Customer satisfaction and loyalty will improve if employees perform well in the customer-oriented process. The study's purpose is to examine the links between doctors' job happiness, customer orientation, customer satisfaction, and customer loyalty in international hospitals in Vietnam. In international hospitals, data was collected from 204 clinicians and 408 patients. By applying structural equation modeling. The study found that doctors' job satisfaction had a significant impact on customer orientation and satisfaction in international hospitals. Customer satisfaction may be improved with a good customer orientation. The doctors' job satisfaction and effective customer orientation improve customer satisfaction and loyalty towards international hospitals in Vietnam, thanks to the impact of spreading emotions. In particular, if doctors are satisfied with their jobs, it promotes customer satisfaction when using medical services at international hospitals. The study has proved the essential role of customer-oriented strategy and doctors' job satisfaction in customer satisfaction and loyalty towards international hospitals.

In rapid prototyping, the optimal part orientation during fabrication is critical as it can improve part accuracy, minimize the requirement for supports and reduce the production time. Through investigating the geometric issues of STL model and process planning of RPM, This paper establishes optimizing model based on the considerations of staircase effect, support area and production time. The general satisfactory degree function is constructed employing the multi-objective optimization theory based on the general satisfactory degree principle. The best part-building orientation is obtained by solving the function employing generic algorithm. Experiment shows that the methods can effective resolve the part-building orientation in RP.

Purpose: This study sheds light on the need for trust in buyer-seller relationships in supply chains and explores why long-term orientation is important. It also investigates the effect on relationship performance. This study provides implication on how to build robust supply chains. Methodology: A survey was conducted with firms with supply chains in South Korea. A total of 350 valid questionnaires were analyzed through Entrust Survey-a sampling company. Structural equation modeling (SPSS 18.0 and AMOS) was employed to test the hypotheses. Results: Cognitive trust had a positive effect on emotional trust. Emotional trust had a positive effect on long-term orientation but did not have a significant effect on relationship performance. Long-term orientation was proportionate to relationship performance. Conclusions: Trust is a critical factor in supply chains. As business environments are rapidly changing, the uncertainties are also meaningful. Supply chains have collapsed owing to COVID-19, the Russia-Ukraine war, and the U.S.-China trade war, and they are only just recently being rebuilt. Maintaining relationships with supply-chain partners is vital, and promoting cognitive and emotional trust is necessary.

Layered manufacturing(LM) is emerging as a new technology that enables the fabrication of three dimensional heterogeneous objects such as Multi-materials and Functionally Gradient Materials (FGMs). Among various types of heterogeneous objects, more attention has recently paid on the fabrication of FGMs because of their potentials in engineering applications. The necessary steps for LM fabrication of FGMs include representation and process planning of material information inside an FGM. This paper introduces a new process planning algorithm that takes into account the processing of material information. The detailed tasks are discretization (i.e., decomposition-based approximation of volume fraction), orientation (build direction selection), and adaptive slicing of heterogeneous objects. In particular, this paper focuses on the discretization process that converts all of the material information inside an FGM into material features like geometric features. It is thus possible to choose an optimal build direction among various pre-selected ones by approximately estimating build time. This is because total build time depends on the complexity of features. This discretization process also allows adaptive slicing of heterogeneous objects to minimize surface finish and material composition error. In addition, tool path planning can be simplified into fill pattern generation. Specific examples are shown to illustrate the overall procedure.
