The purpose of this study looks for the directions to improve the performance evaluation of cook by examining the perceptions for performance of cook by supervisors in hotel restaurant. In order for this purpose, this study focuss on two areas: (1) the significant differences of each hotel type on the perceptions of each performance evaluation item, (2) the significant differences of each kitchen type on the perceptions of each performance evaluation item in terms of two different types of hotel. To examine (1) and (2), this study uses Student t test and anova analysis. The findings from this study have both theoretical and practical implications. Implications of these findings are discussed.

A client/server system has become the computing architecture for the business organization which seeks competitive edges. Technically, a client/server system places application processing close to the user and thus increases performance. This paper's two primary goals are (i) to present a performance model for client/server database systems and (ii) to demonstrate analytically the effectiveness of client/server computing in comparison with other computing architectures via an illustrative example. The model is most likely to be used as a practical performance guide for client/server computing.

The focus of this research is to realize the function which is equivalent to the active suspension system, with controlling semi-active suspension through the attenuation of power variable damper in lower cost and smaller energy. Actually some semi-active suspension systems have been adopted, but they are not sufficient in performance. The authors intended to develop more effective and practical system and applied the optimal control technique. The results of experiments with practical suspension system showed a degree of improvement of comfortableness.

This article presents the design, control, and implementation of a small quad-rotor system under the practical limitation of being cost effective for private use, such as in the cases of control education or hobbies involving radio-controlled systems. Several practical problems associated with implementing a small quad-rotor system had to be taken into account to satisfy this cost constraint. First, the size was reduced to attain better maneuverability. Second, the main control hardware was limited to an 8-bit processor such as an AVR to reduce cost. Third, the algorithms related to the control and sensing tasks were optimized to be within the computational capabilities of the available processor within one sampling time. A small quad-rotor system was ultimately implemented after satisfying all of the above practical limitations. Experimental studies were conducted to confirm the control performance and the operational abilities of the system.

Research and development (R&D) methodology for the practical use of accident tolerant fuel (ATF) in commercial light water reactors is discussed in the present review. The identification and quantification of the R&D-metrics and the attribute of candidate ATF-concepts, recognition of the gap between the present R&D status and the targeted practical use, prioritization of the R&D, and technology screening schemes are important for achieving a common understanding on technology screening process among stakeholders in the near term and in developing an efficient R&D track toward practical use. Technology readiness levels and attribute guides are considered to be proper indices for these evaluations. In the midterm, the selected ATF-concepts will be developed toward the technology readiness level-5, at which stage the performance of the prototype fuel rods and the practicality of industrial scale fuel manufacturing will be verified and validated. Regarding the screened-out concepts, which are recognized to have attractive potentials, the fundamental R&D should be continued in the midterm to find ways of addressing showstoppers.

본 연구는 공업계 고등학교 금속과 금속처리 전문교과에서 열처리 및 인장시험 관련 직무 또는 작업을 수행할 때 요구되는 지식, 기능, 태도 및 수행절차별 하위요소들의 총합인 실무능력은 무엇인가에 대한 질문에서 시작되었다. 본 연구에서는 실무능력 하위요소를 메이거가 직업 교육의 주요 대상인 일에 근거를 두고 분류한 다섯 가지 성취 행위 유형분류 기준에 따라 분류하였다. 이들 실무능력의 하위요소 분류 기준에 따라 금속 열처리 장치 조작원과 인장시험검사원의 직무분석과 기능위계 분석을 바탕으로 공업계 고등학교 열처리 실무능력과 인장 시험 실무능력의 하위 요소를 추출하고 전문가 집단에게 그 타당도를 검증받았다. 열처리와 인장시험의 실무능력 하위 요소들은 공업계 고등학교 교육목표인 인지적 영역, 기능적 영역, 정의적 영역, 즉 지식, 기능, 태도의 성취행위에 모두 포함되는 요소이며 열처리와 인장시험의 직무 및 작업을 완성하기 위해 상호작용하는 유기적 관계임을 확인할 수 있었다. 본 연구에서 시도한 메이거의 성취 행위 유형 분류기준에 따른 실무능력 하위 요소 도출은 해당 직무와 작업에서 학습자에게 최종적으로 목표로 하는 바가 무엇인가를 명확하게 해주고, 그 기준을 제시해 준다는 측면과, 교육성과를 평가하는데 분명한 기준을 제시해 준다는 측면에서 의의가 있다고 여겨진다.

In this paper, we deal with the model to reward researchers' performance. The rewards which disregarded the preference of researchers don't satisfy researchers, but cause, only conflicts. In order to increase the researchitivity by resolving these researchers' conflicts, we design a new model on the performance rewarding system. For this purpose, we investigate preference structure on the reward of researchers by the$\ulcorner$conjoint analysis$\lrcorner$. And we propose some reasonable and practical programs to reward performance on the basis of the investigation..

본 연구의 목적은 사이버대학의 성과에 영향을 미치는 서비스 특성화 요인을 찾는 것이다. 본 연구에서는 사이버대학의 성과를 교수, 졸업 및 취업, 브랜드 이미지 측면에서 접근하였고, 선행연구를 토대로 하여 사이버대학의 성과에 영향을 미치는 서비스 특성화 요인으로 콘텐츠 다양성, 콘텐츠 품질, 콘텐츠 실무지향성, 강의 실재감, 학습관리를 도출하였다. 연구모형을 검증하기 위해 중국의 사이버대학에 재학 중인 대학생들을 인터넷 설문을 배포하여 총 170부의 유효설문을 수집하여 실증 분석하였다. 실증 분석한 결과, 다음과 같은 다섯 가지의 연구결과를 확인하였다. 첫째, 콘텐츠 다양성 수준이 높을수록 사이버대학의 성과는 높아지는 것을 확인하였다. 둘째, 강의 콘텐츠 품질이 우수할수록 사이버대학의 성과는 높아지는 것을 확인하였다. 셋째, 콘텐츠 실무 지향성이 높을수록 사이버대학의 성과가 높아지는 것을 확인하였다. 넷째, 강의 실재감이 높을수록 사이버대학의 성과는 높아지는 것을 확인하였다. 다섯째, 학습관리 수준이 높을수록 사이버대학의 성과가 높아지는 것을 확인하였다. 지금까지는 사이버대학에 관한 선행연구들은 주로 학습자의 학습성과 향상 방안을 찾는데 초점이 맞춰져 있었다. 그러나 본 연구에서는 이러한 선행연구와 달리 사이버대학의 비즈니스 모델 측면에 초점을 두고 접근하였다. 왜냐하면 교육 분야의 경쟁이 점차 글로벌 경쟁으로 심화되고 있어 기존의 비즈니스 모델로는 한계가 있어 새롭게 재검토할 필요가 있기 때문이다.

This paper presents some practical design issues that should be carefully considered when a notch filter is included in a linear feedback controller. A notch filter is generally used to compensate the effects of resonant modes that may result in poor performance. It is very common that the practical engineers prefer to add such a notch filter after having previously designed a feedback controller without the filter. It is known that the resulting performance by this approach is not seriously different from when a feedback controller is designed for a plant previously compensated by a notch filter. However, we will point out that there are some cases where both approaches have different performances. In order to show this, a low-order controller design using the partial model matching method has been applied to a linear time invariant (L Tn model. The results suggest that there is a tendency to achieve much better time responses in terms of reducing the overshoot and shortening the settling time, and in the frequency domain characteristics such as the sensitivity function and the stability margins when the design of a feedback controller after including a notch filter is carried out.
