In testing the moving balance of a rotor instead of strobotron system here to for in use, making the pick up touch the rotor without putting the subject on the testing table, we can observe both the corrected original point and its unbalance point which appeared on the Braun tube screen with naked eyes. Then we can do our correcting job with rapidity.

The basic signals for electronic engine control are velocity and degree of the engine cam shaft. The CPS sensor used for this signal and magnetic pick-up type CPS sensor is more popular. It is very important thing analyze this signal correctly. If there are some mistakes at the analysis, like a noise, The engine do not working at the best status, it will generate some noise, emit exhaust fumes and waste more gases. In general way to analysis this signal, you use zero-level detector circuit and in order to reduce the error you must use another sensor like a TDC sensor. In this paper, We proposed the analysis method using electronics circuits for magnetic pick-up type CPS sensor. We designed Comparison level detector circuit, Differential circuit and Full-rectifier circuit for detected the Long tooth and Short tooth level correctly without another sensor. We expected it is useful for more reliable engine control.

The purpose of this article is the consolidation of several methods in fabrication of Konus denture. It is different Konus denture from traditional Clasped removable partial denture in the procedures of construction. There are multiple procedures of fabrications of inner and outer crowns in the construction of Konus denture. It is important to fabricate the inner crown, the outer crown and the denture framework in construction of Konus denture. Each procedure should be performed exactly. However, there are many procedures in fabrications of them, and thus, the operator and technician bear trial and error. This article consolidate the multiple methods of fabrications of components of Konus denture. The first method is completion of inner crown, outer crown and denture after one impression taking. The second method is the procedures of cementation of inner crown, impression taking of edentulous area, and completion of outer crown and denture. The third method is the procedures or pick up impression taking of inner crown and completion of outer crown and denture on the inner crown of working cast. Each method is acceptable, but operater and technician should be accustomed with their own systemic procedures and minimize the errors in the construction of denture.

본 논문은 조선소에서 계획기간동안 각 플랜트의 생산일정에 따른 블록의 모든 수송요구량이 미리 알려져 있는 정적인(static) 수송환경을 고려한 트랜스포터 일정계획문제를 다룬다. 조선소 내에서 블록들의 수송은 몇 가지 특성을 가진다. 500톤을 초과하는 거대 블록들은 2대 이상이 결합된 새로운 형태의 트랜스포터를 이용하여 운반된다. 운반이 요구되는 블록들 중 일부는 계획기간동안 규정된 출발요구시각에 pick-up되기를 요구하는 반면 나머지 블록들은 계획기간동안 규정된 도착요구시각 전에 delivery되기를 요구한다. 이러한 트랜스포터의 결합 및 시간 제약은 문제를 더욱 복잡하게 하는 요인이 된다. 본 논문에서는 계획기간 내에 모든 블록운반 요구사항들(출발지와 도착지, pick-up과 delivery 시각, 톤수, 결선 등)을 만족시키는 트랜스포터 일정계획문제를 다룬다. 트랜스포터 일정계획문제에서 중요한 주제는 총 로지스틱스 시간 (공차운행시간, delay 시간 및 tardy 시간)을 최소화하기 위해 계획기간 내에 최소의 트랜스포터 운영대수로 각 트랜스포터에 어떤 블록을 할당하고 어떤 순서로 운반할 것인 지를 결정하는 것이다. 이에 본 논문에서는 주어진 트랜스포터 일정계획문제를 해결하기 위해, 1단계에서 최소비용 네트워크 흐름문제를 근간으로 트랜스포터의 최소사용대수를 구하고 이를 기초로 2단계에서 각 트랜스포터에의 블록 할당과 운반순서를 결정하는 2단계 휴리스틱 알고리즘을 제안한다.
