  • Design of an in-process feedback control system has been studied for precision grinding. A grinding system consists of a grinding tool, a turn table and a disk-shaped workpiece on the table is taken as an object. A grinding process model has been deduced which gives some reasoning about the process errors. In the control system the tool position is actively controlled by an electro-magnetic actuator in-process. The ground error is feedback to compose a closed-loop control system and an optimal PID controller is applied. Some control performances such as transient response and disturbance such as transient response and disturbance attenuation have been examined, which convinces the effectiveness of the control. Some methods for implementation of the control. Some methods for implementation of the control have been suggested from a standpoint of practical application.

  • 본 연구는 의생활 교육내용을 임파워먼트 향상을 목표로 하는 비판과학 관점의 가정과수업으로 구성하여 청소년들이 직면하는 의생활 문제를 해결하고 나아가 새로운 의생활 문화를 창조시킬 수 있는 교수·학습 과정안을 개발하고자 하였다. 이를 위해 Yoo와 Lee(2010)가 구체적으로 해석한 Laster(1986)의 교육과정 개발 과정을 적용하여 개념화한 후, Brown(1979)의 실질적 내용구성과 미국 위스콘신 주에서 개발한 교사용 지도서 "A Teacher's guide : Family, Food and Society"(Staaland & Storm, 1996)에서 제시된 실천적 추론의 개념적 틀을 적용하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 의생활 관련된 문헌들을 고찰한 결과를 토대로 의생활과 관련된 지속적인 관심사로는 '사회 내의 가족을 위하여 의생활과 관련하여 무엇을 해야 하는가?'로 선정하였다. 추구하는 가치목표는 자유가 많고 책임이 큰 상태인 복합적인 위치로 정의하여, 상호의존성, 감정적 성숙, 지적발달, 의사소통 능력 등을 학습의 목표로 삼았다. 교육내용과 활동 구조를 위해 교육내용의 개념적 틀로 실천적 추론 과정을 사용하였으며, 하위 관심사, 광의의 개념, 하위 개념과 지적·사회적 기술을 포함시켰다. 둘째, 실천적 추론 단계를 토대로 의생활 영역의 교수·학습 과정안을 개발하였다. 그 결과 총 5개 모듈의 12차시 과정안을 개발하였으며, 읽기 자료, 그림 자료, 모둠활동 자료, 동영상 자료 등을 포함하여 총 31개의 학습지를 개발하였다. 본 연구결과, 실천적 추론과정을 수업에 새로이 시도해 보고자 하는 교사들이나, 실천적 추론 과정을 현장에서 실행하는 데에 어려움을 겪은 교사들에게 바로 적용할 수 있는 자료로 활용될 수 있다.

  • 학생들이 실제 문제 상황에서 수학을 이용하고 문제를 해결하는 것은 수학교육의 중요한 목표이다. 이 연구는 수학적 모델링이 그러한 수학 학습의 목표에 적합하다고 보고 수학적 모델링을 통해서 학생들이 어떤 수학내용을 학습하고 어떤 추론을 경험하고 사용하는지 살펴보았다. 학생들은 수학적 모델링 과정에서 학교수학에서 강조되어 왔던 연역과, 규칙성을 찾는데 기여했던 귀납 뿐 아니라 여러 유형의 가추를 사용하였다. 하나의 사례 연구를 통해 일반화할 수는 없지만, 수학적 모델링에서 연역은 수학적 모델이 옳은지 현실에 비추어 확인하는 과정에서 그리고 수학적 결과를 유도하여 해를 구할 때, 귀납은 수학적 모델이 옳은지를 실험적으로 검증해 보고자 할 때 사용되었다. 가추는 현실 모델로부터 수학적 모델을 추상화하고, 수학적 결과에 대한 현실적 근거를 제시하는 해석을 하고, 현재의 수학적 모델을 수정하여 새로운 수학적 모델을 도출하는데 사용되었다.

  • This study focuses on establishing theoretically-reasonable framework of evaluation areas and items for the informatization program and analyzing the weights for each area and item by means of the AHP. To obtain the goal of this research, firstly, based on broadly reviewing previous literature and logical reasoning, the evaluation criteria were Identified and conceptualized, which were 3 evaluation phases, 5 evaluation areas, and 22 evaluation items. Secondly, The data used for calculating the weight values for the evaluation criteria were collected from 48 academic and practical experts in the field of the informatization program promotion using internet survey. Thirdly, the relative weights among evaluation phases, evaluation areas, and its items were derived by AHP analysis. The findings of this study are thought not only to be useful as a practical guideline in performing evaluating the informatization program but also to provide significant basis for constructing the theoretical framework of evaluating method and management of the informatization program.

  • This paper presents a practical fuzzy expert system to diagnose various faults occurred in local power systems. This integrated system can diagnose all faults occurred in a transmission network and substations. In this paper. the fuzzy reasoning of the diagnostic process is discussed in detail. The discrimination of false operations and non-operations of protective devices as well as the fault identification scheme are also analyzed together with the fuzzy inference process.

  • Planning/planning stage Construction cost prediction is very important. In particular, flexible thinking is required to predict the construction cost by reflecting rapid market changes and current conditions. Therefore, in this study, we tried to consider the process for calculating the construction cost of an apartment house in a more accurate planning/planning stage. First, cases were collected based on the classification system by construction type. Second, the construction cost was predicted using the case-based reasoning technique. Third, the composition ratio by construction type of the most similar case was applied to the derived construction cost. Finally, the construction cost was predicted based on practical corrections reflecting the market and field conditions.

  • This study aims to construct the integrative performance evaluation model of informatization programs. In order to achieve the purpose of research, first of all, the three major theoretical paradigms (technical/functional, economic/financial, and interpretive/alternative paradigms) are comparatively analyzed concerning their philosophical and methodological perspectives. Also, a number of important studies and research model in the area of IS (Information Systems) evaluation are critically reviewed. And then actual problems and limitations on the process of implementing IS performance evaluation are sought through investigating domestic and foreign practices. Based upon theoretical and practical review of informatization evaluation and logical reasoning, the components of ideal performance evaluation scheme for informatization program are derived, and the integrative performance evaluation model which can comprehensively represent the relationship among the components is conceptually proposed. For researchers, this study provides the theoretical basis for reasonably deriving the performance variables of informatization programs and empirically validating the performance of managing informatization programs. And in real world, the results of this study are very likely to contribute to presenting the practical guideline for desirably implementing performance evaluation of informatization programs.

  • In order to search for the causes of having difficulty with the scientification task of the Korean medicine, the definition and conception of science were reviewed first and then formalization of reasoning scheme and a practical method of scientification were proposed. Science in its definition is meant by foundation of method and system for production of scientific knowledge not by knowledge of science itself. The formation of science is composed of complex processes including not only scientific knowledge but also politicosocial output containing activity of scientist society, spreading of social value and intercommunication. The production of scientific knowledge of Korean medicine is begun from logicality of the differential diagnosis and treatment theory through abductive verification of analogical inference by yinyang and 5 phase theory. For the commensurability between the various heterogenic theories within Korean medicine, the scientific activity of collecting, compiling, analyzing, distributing, and discussing the significant knowledge gained through abductive verification in the experiment and clinical process should be formed broadly. Based on these knowledge database, organization of scientist society with Korean medicine, life science, medical engineering, social expansion and generalization of pattern conception, and then social propagation and contribution for national health should be driven forward.

  • The clinical clerkship focuses students on developing their ability to perform comprehensive diagnosis and management of patients with common undifferentiated problems by the integration of knowledge and clinical reasoning. Therefore, the clerkship evaluation system should assess their actual problem solving and professional behavior. However, concern remains that clerkship evaluations are imprecise and highly variable. This review is designed to provide faculty members with concepts, options, and a methodology to actively teach and evaluate the clinical clerkship, as well as offer encouragement and inspiration to medical students. We reviewed past and current clinical clerkship evaluations and discuss several tips to improve clinical excellence such as continuity, transparency of the evaluation process, a faculty development program, practical examination of clinical skills, implementation of a checklist for recording exposure and skills, providing prompt and constructive feedback to students, self-evaluation of professional performance, varying multi-faceted assessment combinations, being outpatient clinic-centered, and having dedicated faculty members who give students one-on-one contact with a preceptor.
