This research aimed to compare the detection methods of Anisakis simplex in Sea fish by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and macroscopic inspection. We examined 18 Trichiurus lepturus, 11 Scomber japonicus, and 65 Todarodes pacificus collected from the retail markets in the areas of Uljin, Kyuonggi province and Seoul. As the result of examinations, we found that detection rate of Anisakis simplex by macroscopic observation was 89% in Trichiurus lepturus, 90.9% in Scomber japonicus, 32.3% in Todarodes pacificus. The detection rate of Anisakis simplex by PCR-RFLP was 77.7% in Trichiurus lepturus, 81.8% in Scomber japonicus, 26.1% in Todarodes pacificus. We could conclude that PCR-RFLP method of Anisakis simplex was more specific rather than macroscopic observation.

High-speed machining is one of the most effective technologies to improve productivity. Because of the high speed and high feed rate, high-speed machining can give great advantages for the machining of dies and molds. High speed machine tool makers try to

현실적으로 최근 공작기계의 고속화가 급속히 진전되고 있는 것이 세계적인 기술 추세이다. 이와 맞물려 고속공작기계 내지는 고속가공시스템 표준 평가방법의 정립이 필요하다. 이에 본 논문은 고속가공기의 특성이나 성능평가 방법을 위해, 가공방향 조도상차이, 표면조도, X,Y축 이송에 의한 직각도 및 Z축 떨림, 상한돌기, 직경감소와 미소지정, 열변형랑, 가공시간등의 테스트항목을 선정하여 육안검사시편을 개발 및 가공함으로써, 고속가공기의 특징을 분석하여 최적의 기계성능을 활용할 수 있게 하고자 한다.
