This study introduces 2007 criteria of Malcom Baldridge National Quality Award (MBNQA) for performance excellence. Baldridge criteria is composed of the seven categories such as leadership, strategic planning, customer and market focus, measurement, analysis, and knowledge management, workforce focus, process management, and results. Moreover this paper proposes various integrated systems with MBNQA.

Best practices are the best ways to perform a business process. Benchmarking, the search for those best practices that will lead to superior performance of a company, is indispensible to gain and maintain a competitive edge. Best practices of quality management in the world-class companies are examined. Customer-centered strategy, employee selection and training, employee satisfaction, customer satisfaction, performance measurement are considered in this paper.

An extended robust H$\infty$ filter is proposed for a nonlinear uncertain system. We also analyze the characteristics of the proposed filter such as an H$\infty$ performance criterion using the Lyapunov function method. The analysis results show that proposed filter has a robustness against disturbances such as process and measurement noises and against parameter uncertainties. Then the in-flight alignment for a strapdown inertial navigation system is designed using the presented filter. Simulation results show that the proposed filter effectively improve the performance.

The purpose of this study is to propose a throughput costing as a performance measurement tool to measure cost indicators, which are one of the indicators for evaluating organizational performance in a smart factory manufacturing environment. An empirical study by questionnaire was conducted, and 60 experts were surveyed to verify the hypothesis. As a result of the study, it was concluded that the information provided based on throughput costing is helpful in cost measurement and in evaluating organizational performance efficiency and effectiveness, and it was confirmed that this method has usefulness to support the planning and control process. It is proposed that the use of throughput costing by constraint theory, which can maximize throughput and optimize inventory levels in the manufacturing process, can find solutions to bottlenecks affecting the efficiency and effectiveness of organizational performance.

An on-line refractometer made of easily obtainable materials is built to determine the concentration of an alcohol solution, and its performance is examined by applying to the system of ethanol and water. Since the refractive index and the temperature are measured simultaneously, it is possible to compensate the effect of temperature which is not available with an existing on-line refeactometer. Therefore, it can be implemented in the application of process control. The experimental outcome indicates that the home-made refractometer has satisfactory reproducibility and reasonable accuracy for the industrial application.

The digital HPTV velocity field measurement consists of four steps: recording, numerical reconstruction, particle extraction and velocity extraction. In the velocity extraction process, we improved PTV algorithm to extract the displacement of particle each placed in 3D space. Because a digital recording device was used, some factors such as a spatial resolution, numerical aperture, and particle concentration can affect the performance of the digital HPTV. Especially, a particle concentration ($C_{o}$) affected tile reconstruction efficiency in numerical reconstruction and particle extraction process. In this paper, the reconstruction efficiency was analyzed experimentally with different particle concentration. Optimal reconstruction efficiency was shown in the range of $C_{o}$=$13\∼15$ particles/$mm^{3}$.

This paper deal with the design of noncontact In-process measurement system which measures the surface roughness during cylindrical grinding. The measuring system is extremely simple and the apparatus proposed is composed of a laser unit, photodetector and optical system. The experimental performance of the apparatus is satisfactory and good results are expected in the actual use. During operation, the surface of a workpiece Is continuously scanned by a laser beam. The experimental results show that the presence of chattering, loading and glazing can be detected sensitively along both circumferential and feed directions and the surface roughness value is obtained from the reading along the feed direction.

Recently, electronic equipments become smaller, more functional, and more complex than before. As these trends, MLC(multi-layer ceramic) circuit has been emerged to a promising technology in semiconductor inspection industry. Especially, multi-layer ceramic which is consisted of many fine-pitch multi-hole is used to produce a semiconductor inspection unit. The hole is processed by UV laser. But, working conditions are changed all the time. Therefore real time measurement of fine-pitch multi-hole is very important method for ensuring performance. In this paper we found the best method for illuminating and auto focusing. And, we verified our equipment.

This paper describes a measurement & verification scheme for the high efferent lighting program in Demand Side Management (DSM), which was Introduced in the beginning of the 1980's in Korea With the dramatic changes in the circumstance of power industry in Korea. It is required the reviewing for the existing process of DSM programs and the development of the new process methods/standards on the evaluation of DSM programs. To design an accurate evaluation scheme for the high efficient lighting program. In this paper, we develop an evaluation prototype for the high efficient lighting program using measurements and stipulated factors. The proposed scheme is tested by practical measurements and modified stipulated factors Results from the case studios show the proposed scheme could provide the practical performance evaluation results with promising accuracy.

Immobilization of conducting nanoparticles on a nanogap comprising two electrodes spaced at a distance comparable to the particle size can be used as a simple and sensitive method of detecting the particles. In this work, we have examined the performance of the nanogap devices in the measurement of metallic nanoparticles, particularly gold nanoparticles (Au NPs). Detection of pM-level Au NPs in an aqueous suspension was quite straightforward irrespective of the existence of non-conducting materials. Speed of detection or the time necessary for the completion of the measurement, however, was strongly dependent upon the immobilization process. Active trapping process was found to be much more efficient and also effective in the detection of nanoparticles than its passive counterpart.
