The present work is aimed at investigating an unusual variation in flow and performance characteristics of a small propeller fan at low flow rates. A performance test of the fan showed dual performance characteristics, i.e., radial type characteristics at low flow rates and axial type at high flow rates. Dual performance characteristics of the fan are numerically investigated using viscous flow calculations. The Finite Volume Method is used to solve the continuity and Navier-Stokes equations in the flow domain around a fan. The performance parameters and the circumferentially averaged velocity components obtained from the calculations are compared with the experimental results. Numerical values of the performance parameters show good agreement with the measured values. The calculation simulates the steep variations of performance parameters at low flow rates and shows the difference in the flow structure between high and low flow rates. At a low flow coefficient of $\Phi$=0.2, the flow enters the fan in an axial direction and is discharged radially outward at its tip, which is much like the flow characteristics of a centrifugal fan. The centrifugal effect at low flow rates makes a significant difference in performance characteristics of the fan. As the inlet flow rate increases, flow around the fan changes into the mixed type at $\Phi$=0.24 and the axial discharge at $\Phi$=0.4.

The robust control problem of the linear systems with uncertainty is classified as the robust stability problem guaranteeing the stability and the robust performance problem guaranteeing the disired performance. In this paper, we considered the robust performance analysis problem, which find the upper buund of the quadratic performance of the uncertain linear system, and the robust guaranteed performance controller design problem which design a controller guaranteeing the desired quadratic performance. At first, we treated the analysis problem and presented the two results; one is dependent on the performance of the nominal system and another is independent on this. And we treated the design method guaranteeing the desired performance for the uncertain linear systems, Finally, we show the usefulness of our results by numerical examples.

Purpose: The purpose of this study is to examine the influence of resilience and work engagement on performance of managers in the automotive sector in Morocco. It analyses the mediating effect of work engagement between resilience and manager performance. Though earlier studies have focused on the effect of resilience on employee performance and work engagement. none has looked at the mediating role of work engagement in this context. Thus, the present paper attempts to fill this literature gap. Research design, data and methodology: A confirmatory survey was conducted among a sample of 196 employees of automobile companies in Tangier-Morocco. A structural equation analysis using SmartPLS was performed while Preacher and Hayes (2008) method was used to analyze the mediation effect. Results: a) Manager resilience has a positive influence on work engagement, which further influences their performance; b) there is a statistically insignificant relationship between resilience and manager performance; c) Structural equation modelling analysis shows that work engagement partially mediates the relationship between resilience and manager performance. Conclusion: Theoretical contributions, practical implications, and future research directions are discussed.

Purpose - The buyer's right to withhold performance is a useful and important self-help remedy to protect himself from the seller's breach of contract, and it is also the coercive means to induce the seller to perform his part of contract. However, the buyer's exercise of such a right often exposes himself to the risk of breaching the contract. This is generally due to his ignorance when he is entitled to the right and also uncertainties inherent in the law. Therefore, the purpose of this paper is to examine what the requirements should be fulfilled before the buyer exercises the right for the seller's actual breach of contract. Design/methodology - In order to achieve the purposes of the study, it executes a comparative study of the rules as to the requirements for the buyer's right to withhold performance for the seller's actual non-performance under the CISG and the CESL. It mainly focuses on performance due, the seller's non-performance, the buyer's readiness to perform and the requirement of notice. Findings - The main findings of this comparative study can be summarized as follows: Although the CISG has no expressive provision for the buyer's general right to withhold performance for the seller's actual non-performance, it may be inferred from the general principles the CISG underlies, synallagmatic nature of the contract. In addition, it can be drawn by analogy from relevant provisions of the CISG. On the other hand, the CESL expressively provides that the buyer has a general right to withhold performance where the seller fails to tender performance or perform the contract. Therefore, it seems that the position of CESL is rather easier and more apparent to allow the buyer to withhold performance for the seller's non-performance. Originality/value - Most of the existing studies on the right to withhold performance under the CISG have centered on the right to withhold performance for an anticipatory breach of contract. On the other hand, there have been few prior studies on the right to withhold performance for the actual nonperformance during a contractual period of performance. Therefore, this paper examined the requirements for the buyer's right to withhold performance under the CISG and the CESL in a comparative way for the seller's actual breach of obligation. In this conclusion, it may provide practical and legal considerations and implications for business people who are not certain about the right to withhold performance.

본 연구는 기업의 종업원의 성과요인을 개인적, 조직적, 제도적 요인으로 나누고 이에 따른 성과평가결과와의 관계를 실증적으로 분석하였다. 최종 417개의 표본을 바탕으로 SPSS와 AMOS를 이용한 결과를 요약하면, 다음과 같다. 성과 요인 중 직무 만족과 공정한 성과제도는 개인성과 평가결과에 유의미한 양(+)의 관계를 보였고, 안정적 대인관계는 뚜렷한 상관관계를 찾아보기 어려웠다. 직무 만족(β= 0.432, t= 7.375^***)의 영향력이 가장 컸으며, 공정한 성과제도(β= 0.127, t= 2.406^*)가 그 다음이었다. 이는 성과 원인이 직무에 만족 한 경우와 조직의 성과제도가 공정하다고 인식하는 것이라 할 수 있겠다. 그러나 안정적 대인관계 즉, 다른 사람들로부터 원만한 관계를 하고 심리적 안정이 동반되는 대인관계는 성과요인이 아님이 밝혀졌다. 이러한 실증분석 결과를 바탕으로 성과요인에 대한 논의, 그리고 시사점과 향후 연구방향에 대해 제시하였다.

The purpose of this study is to develop a Framework for Performance Assessment in Science Education(FPASE). Science educators in the past have paid more attention to science curriculum and teaching strategies than assessment. In recent years, attention has turned toward performance assessment which addresses the concerns of science curriculum and instruction, and which is consistent with goals of science education at various levels of interests. Science educators are trying to do performance assessment, yet they don't have a framework that is highly qualified in terms of science educational objectives for the future, and advantages of performance assessment. We, therefore, have developed a framework for performance assessment in science education, which may be useful for science teachers to understand and assess their students' abilities. We have extracted seven domains covering students' various abilities as the important objectives of science performance assessment and grouped them into three categories: General, Science specific, and Intermediate abilities. And we developed a F-PASE with a three dimensional solid figured structure, and illustrated it as the configuration of a com. F-PASE is useful for science teachers to develop and select a science performance assessment as well as have a more advanced understanding of their students' abilities. It is a creative and novel assessment framework in terms of structure, configuration, functions and meanings. It also suggests a new vision of an assessment framework in science education.

This study aims to explore the relationships between strategic planning, strategic maneuverability, and firm performance in the current dynamic business environment. It employs a quantitative research method and reports on a survey, using a questionnaire, of service companies in Indonesia's oil and gas industry. Of the 337 companies selected by simple random sampling from a vendor database, responses were received from 70 companies. The analysis was performed using Partial Least Square Structural Equation Modeling and SmartPLS software. The analysis consisted of descriptive statistics, evaluation of the measurement model, evaluation of the structural model, and hypotheses testing. The results show that both strategic planning and strategic maneuverability have a positive relationship with firm performance. In addition, there is a positive relationship between strategic planning and firm performance through the mediating role of strategic maneuverability. The findings suggest that the organizational agility, organizational flexibility, and organizational responsiveness that constitute strategic maneuverability have a positive direct and indirect effect on firm performance, namely financial performance, customer performance, internal process performance, and learning and growth. This study contributes to the strategic management literature and the theory of maneuvers by providing empirical evidence on the relationship between strategic planning, strategic maneuverability, and firm performance.
