  • Purpose: The purposes of the study were to examine whether nurses' followership style influence organizational effectiveness and to test the model of organizational effectiveness including the factors of nursing organizational culture, leadership style, and followership style. Methods: Data were collected from July 10th to september 20th in 2006 from 451 nurses working in four acute care hospitals. Data analysis were performed by Chi-square test, ANOVA, Duncan test, Pearson Correlation, and maximum likelihood estimation, using the SAS and LISREL 8.30 program. Results: The findings showed that the types of nurses' followership were classified as passive (21.1%), alienated (8.2%), conformist (16.4%), pragmatist (35.9%), and effective style (18.4%). There was significant difference in the organizational effectiveness among the nurses with different followership styles. In testing the path model, transformational, transactional leadership directly influenced followership style. Followership directly influenced organizational effectiveness. Conclusion: The overall fitness of the model was good, evidenced by general fitness index (GFI)=.94, adjusted goodness of fitness index (AGFI)=.82, and root mean square residual (RMSEA)=.06. Based on the findings, it is recommended to develop a program for enhancing effective followership in nursing organization.

  • This paper defines an effectiveness index for optical continuous observation of unknown space objects and presents a range of design variables combinations that can satisfy the effectiveness index from a telescope/mount control system perspective using integrated simulation. The overall system-level simulation was implemented and the tracking performance was analyzed by considering design variables such as target position prediction and frame rate, image processing time and measurement error, target trajectory characteristics, and maneuver performance of mount gimbal. As a result of the analysis, it was confirmed that the continuous tracking performance of the optical observation system is dependent on the combination of frame rate and mount maneuver performance. In a situation where an optical observation system is designed or a similar system is implemented using COTS, an appropriate combination of parameters between design variables can be found through effectiveness analysis simulation as in this study.

  • Purpose: The purpose of this study is to apply the constrained Bayesian estimation methodology for product quality control process and prove the effectiveness of the product management by comparing with the well-known Bayes estimator through data performance result. Methods: The Bayes and constrained Bayes estimators were produced based on the theoretical background and for confirming the effectiveness of suggested application, the deviation index was defined and calculated for the comparison. Results: The statistical analysis result shows that applying the suggested estimation methodology, that is, constrained Bayes estimator improves the effectiveness of the index with regard to reduce the error by matching the first two empirical moments. Conclusion: Considering the advanced Bayesian approaches such as constrained Bayes estimation for the product quality control process, the newly defined deviation index reduces the error for estimating the parameter histogram which is reflected both location and deviation parameters and furthermore various Bayesian perspective approaches seems to be meaningful for managing the product quality control process.

  • A great number of firms have used overall equipments effectiveness index to evaluate the effect of TPM activities. Overall equipments effectiveness is very useful index to emphasize the need of decreasing equipments loss time when TPM system is first implemented. And it is powerful to evaluate prductivity growth rate according to TPM activities when GNP growth rate is high level. However, during the depression period, the increase of overall equipments effectiveness does not contribute fully to the cost down, the reason is that demand is falling. In this paper, we present the rectified TPM activities which can be applied to the depression period, and analysis the improvement activities of production part how to contribute to the cost down,

  • Social Welfare is useful concept for evaluating the effectiveness of an economic policy in micro economics. This paper focuses on Social Welfare(SW) of electricity market incorporating demand response(DR). Competition between DR and generation company is modeled as a simple bid function. DR function can be considered as an negative generation(called Negawatt) and as an element of modified demand function. These two approaches result in the same demand reduction, generation power, and the market price. However, SW in the modified demand function approach is not identical to SW in the Negawatt approach. It makes the numerical index of DR effectiveness less persuasive. This paper proposes modified definition of SW in the demand function approach. The proposed definition of SW leads the DR effectiveness index to be identical to that in the Negawatt approach.
