In this paper, in order to overcome shortcomings of manual inspection for the automotive PWM Shaft, we developed an automated inline inspection system. The automated inline inspection system consists of the work feeder unit, conveying unit, outer diameter check unit, run-out and roundness check unit, machine vision, defective separation unit and status alarm unit. We used the machine vision system for automatic inspection process and designed the inline systems for automatic feeding and selecting process. Also the repeated operation test was performed in order to verify the precision and reliability of the proposed automated inline inspection system.

Dimensions of learning, based on the vast studies on teaming psychology and teaming processes, have been played an important role as one of the frameworks of curriculum and teaming strategies. Dimensions of Learning consist of 5 Dimensions, each of 'Attitudes and Perceptions', 'Acquire and Integrate Knowledge', 'Extend and Refine Knowledge', 'Use Knowledge Meaningfully', 'Habits of Mind'. And each dimension has $3\~8$ lower categories in itself, The elementary 5th grade science lesson emphasizing upon Dimensions of Learning was developed in this study. The lessons dealt with almost every lower categories of Dimensions of learning. We analysed students' scientific attitude and scientific achievement quantitatively after the lesson emphasized upon Dimensions of Learning in comparison with typical lesson laying stress on teachers' guides. The results are as follows; Students' scientific attitude was significantly changed after the lesson emphasized upon Dimensions of Learning. The willingness, positiveness, straightforwardness, and openness of lower categories of students' scientific attitude were more significantly changed especially. But students' scientific achievement was not significantly changed after the lesson emphasized upon Dimensions of Learning.

N/A Effects of Si and Ni addition on the microstructure and mechanical properties of the Cu-12wt.%Al-5wt.%Fe-1wt.%Mn alloy have been investigated experimentally. Microstructure of the as-cast specimen is found to be refined markedly by additions of Ni and Si. By the addition of Ni, volume fraction of the k phase is increased, but volume fraction of the y phase is decreased. Hardness is increased with the addition of Ni, due to increasing of k phase which is harder than y phase. However, Charpy impact value is not significally decreased possibly due to the formation of isolate k phase. (Received February 19, 1998)

본 논문에서는 이동 창 함수 추적기라는 새로운 추적 알고리즘을 제안한다. 본 논문에서는 이동표적의 궤적을 효율적으로 추정하기 위해 과거 궤적의 정보를 포함하는 이동 구간이 선형이라는 가정을 한 선형 창 함수를 적용하여 구현한다. 제안된 알고리즘의 창 함수의 파라메터는 측정 잡음의 영향을 줄이기 위해 그리고 알파-베터 추적기와 비교하여 더 적은 계산량 증가로 빠른 이동 표적 추적을 구현하기 위해 적절하게 선택할 수 있다. 본 논문에서 제안한 창 함수 추적기를 검증하기 위해 잡음상황에서 선형과 비선형 궤적에 대한 컴퓨터 모의실험을 수행했다. 또한 제안된 창 함수 추적기는 초기값에 대한 둔감한 특성과 예측할 수 없는 시변 측정 환경에서 창 함수 추적기를 사용할 경우 더 높은 자유도를 가짐을 보였다. In this paper, we propose a novel tracking algorithm called slide window tracker (SWT) suitable for maneuvering target. To efficiently estimate trajectory of moving target, we adopt a sliding piecewise linear window which includes past trace information. By adjusting the window parameters, the proposed algorithm is to reduce measurement noise and to track fast maneuvering target with little computational increment as compared to ${\alpha}-{\beta}$ tracker. Throughout the computer simulations, we verify outstanding tracking performance of the SWT algorithm in noisy linear and nonlinear trajectories. Also, we show that the SWT algorithm is not sensitive to initial model parameter selection, which gives large degree of freedom in applying the SWT algorithm to unknown time-varying measurement environments.

The purpose of this study was to analyze quantitatively the effects of the biology field-trip inquiry program on elementary pre-service teachers’ evolution related concept, perception and endangered species conservation related knowledge, awareness and attitude. The study subjects were 25 students, one class of science education department of B National University of Education. The biology field-trip inquiry program was consist of 3 steps. The first step was the preactivity at university, second was the main field work at Upo wetland, and the last third step was the post-activity including additional experiments, writing final report. The results of this study were as follows. First, the biology field-trip inquiry program influenced highly significantly the improvement of elementary pre-service teachers’ evolution related concept and influenced significantly those of evolution related perception partly. And the numbers of elementary preservice teachers to acquire precise definition of evolution increased after the biology field-trip inquiry program. Second, the biology field-trip inquiry program significantly improved the elementary pre-service teachers’ endangered species conservation related knowledge, awareness, but did not influenced significantly pre-service teachers’ endangered species conservation related attitude.

A 36-year-old woman with an unremarkable medical history presented for laparoscopic cholecystectomy. Routine preoperative assessment of the patient`s airway revealed normal jaw opening. Upon induction of anesthesia, her jaw locked in a nearly closed position. X-ray and MRI of the temporomandibular joints that were taken postoperatively showed normal findings except for the steeper posterior angles of the articular eminences. During the next induction of anesthesia, intubation was readily accomplished by opening the mandible with a forward pulling of the chin. (Korean J Anesthesiol 2006; 51: 738~41)
