This study examines the effects of trust and commitment on firm performance in the apparel manufacturer-contractor relationships. A total of 92 apparel manufactures participated in the study. Factor analysis, Cronbach's alpha coefficient, and multiple regression analysis were conducted for the statistical analysis. Two factors of trust were identified: credibility and benevolence. Two factors of commitment were identified: affective commitment and calculative commitment. Three factors of firm performance were identified: customer service performance, finance performance, and product performance. The credibility of the apparel manufacture in a contractor had a significant positive effect on the affective commitment of an apparel manufacturer and on the calculative commitment in a contractor. Meanwhile, the benevolence of the apparel manufacture on a contractor had a significant positive effect on the affective commitment of an apparel manufacturer on a contractor. The credibility of the apparel manufacture on a contractor was positively related to customer service performance, finance performance, and product performance. The benevolence of the apparel manufacture on a contractor was positively related to customer service performance and finance performance of an apparel manufacture. The affective commitment of the apparel manufacture in a contractor was positively related to service performance. The calculative commitment of the apparel manufacture on a contractor was positively related to finance performance and to the product performance of an apparel manufacture. The results of this study provides practical guidelines toward exchange partners of apparel manufacturers as to how to facilitate from performance in apparel manufacturer-contractor relationships.

Jettability analysis using one-dimensional(1D) lumped parameter model has been investigated to design the industrial inkjet head with proper drop velocity and drop volume. By simplifying the inkjet head system into an equivalent electrical circuit, lumped model has been developed. Performance of the lumped model is verified by the comparison between measured results of droplet velocity and ejection volume and predicted value. Also, the jetting performance of an inkjet head is characterized by varying the design parameter and driving condition. As a result, simulation results shows good agreement with the experimentally measured value. The developed lumped model enables to easily understand the effect of dimension change and predict the jetting performance.

This paper presents some real performance of two typical bilateral teleoperation benchmark tasks: peg-in-hole and surface tracking tasks. The tasks are performed by an energy-bounding algorithm in the master control and position-based impedance algorithm in the slave control. Performance is analyzed for the position-force tracking capabilities from free space motion to surface contacting motion. In addition, preliminary user performance is evaluated by measuring the completion time and maximum/average contact forces. The quality of the measured performance is also compared with that of other existing approaches.

This study investigates the effects of business environment on the e-business strategy and performance of venture firms. The development of the research model is based on the empirical studies on the strategy literature. The data from the survey was analyzed using Partial Least Squares(PLS). For Daedeok Valley Venture Firms, product innovation differentiation strategy is affected by environmental uncertainty. And, cost leadership strategy tend to be influence by environmental uncertainty. Finally, venture firm's performance is effected by cost leadership strategy and marketing differentiation strategy. However, for in Hsinchu Science Park Venture Firms, product innovation differentiation strategy is affected by environmental uncertainty and heterogeneity. And, marketing differentiation strategy is enhanced by environment uncertainty and industry growth. In addition, cost leadership strategy tend to be influence by environmental uncertainty and heterogeneity. Finally, venture firm's performance is effected by cost leadership strategy and product innovation differentiation strategy.

In this study, the axial-compressor design and performance/flow analysis program is developed. A mean-line analysis was used to determine optimum arrangement of overall geometry and its off-design performance is predicted by stage-stacking method. Three dimensional blade shape is generated using radial equilibrium equation and vortex methods. Various blade shape is generated and their performance is compared. Finally the quasi-three dimensional flow analysis is applied to investigate the detailed flow phenomena.

The rolling stock have to be tested and evaluated on test line before entry into service. The test items consist of traction performance, braking performance and current collection performance, etc. This paper is a study of defining the test items considering the domestic safety law, IEC 61133 and describes how to establish a test measurement system. Also this paper presents how to conduct the traction performance test and test results.

This paper presents an experimental and numerical study on the overall performance and local flow characteristics of sirocco fan in a range hood. Measurement of overall performance for sirocco fans were conducted based on AMCA standard 210. The effects of flow blockages due to the motor inside the fan on the fan performance were investigated by experimentally and numerically and the results were compared with each other. The numerical and experimental results show the inlet flow blockage reduces the performance (ie. fan static pressure, design flow rate, maximum efficiency and free delivery flow rate) of fan. It is found that the blockage makes the flow field highly non-uniform through the blade and cause the efficiency decrement.

This paper presents the influence of the airgap tolerance on performance of a linear induction motor. Construction tolerance of the plate affects directly to the cost and performance of the Linear metro. LIM has around 10[mm] large airgap with many restrictions such as construction tolerance, thermal expansion and bend of the reaction plate, abrasion of the wheel, and so on. In order to have steady performance, the airgap should be uniform. But it is impossible to maintain the secondary reaction plate be flat along with the long track. Therefore the influence of the flatness on performance of a LIM should be investigated.
