  • Field instrumentation has been important part of construction management in embankment on soft ground. Most of all, well organized plan, instrumentation, maintenance, analysis and feed-back to the construction procedure are the key to the successful construction. In this paper, We review problems of field instrumentation has been performed at road construction on soft ground. And then, several proposals to improve field instrumentation and management are suggested

  • The purpose of this study was to observe the resulting canal shape after using hand, sonic and ultrasonic instrumentation. Thirty canals from extracted human upper or lower 1st and 2nd molars were divided into 3 groups: hand, sonic and ultrasonic instrumentation group. 10 canals of each group were individually prepared with one of three instrumentation methods. After instrumentation and histological processing, apical, middle and coronal third cross sections were examined on the roundness of the canal by microscope. The result were as follows. 1. All experimented groups showed no significant difference in canal roundness regardless of size and level of the canal. 2. Sonic air instrumentation groups revealed Significantly better canal roundness than ultrasonic groups at the middle third of the fine canal. 3. In ultrasonic instrumentation groups, the roundness of the large canal was significantly better than that of fine canal.

  • 본 논문에서는 공군에서 운용중인 전투기를 활용한 비행시험 수행 시 비행자료를 얻기 위한 외장형 계측시스템 개발에 대하여 서술하였다. 전투기의 외장형 계측시스템은 계측 포드와 영상 포드로 구성된다. 계측 포드는 GPS/AHRS 센서를 이용하여 전투기 비행자세, 속도 및 고도 등의 비행자료를 측정하며, 영상 포드는 2대의 고속카메라와 1대의 일반카메라를 사용하여 비행영상을 획득한다. 개발한 외장형 계측시스템은 환경시험과 지상시험, 그리고 전투기에 장착하여 비행시험을 수행함으로서 성능을 입증하였다.

  • This paper proposes a new medical information management system to be used or small to medium sized clinics and hospitals. The system is designed to process, analyze and manage each patient's clinical record using database technique. The structure of the database was determined and implemented through careful and rigorous study of medical practices in Korea and, therefore, reflects the needs of information management in Korean medical community. Furthermore, a sophisticated inference engine that can deduce possible disease from the result of medical examination is added to the system to provide doctors with a guideline in medical diagnoses.

  • The purpose of this study was to evaluate the root canal transportation and remaining dentin / cementum thickness after using hand and ultrasonic instrumentation in the curved mesial root canals of extracted human mandibular molars. Fourty - six clear polyether blocks were made and randomly divided into two groups: hand instrumentation group with K - Flex files and ultrasonic instrumentation group with Suprasson SP unit. All root canals were instrumented to a size corresponding to a # 30 K - Flex file 1mm short from the radiographic apex. The roots were then sectioned perpendicular to the long axis so the apical and middle third could be evaluated with the Zoom stereomicroscope. The results were as follows : 1. In the total amount of removed dentin at middle third level, there was not significant difference between the hand instrumentation and ultrasonic instrumentation (P>0.05). 2. In the total amount of removed dentin at apical third level, there was more removed by the ultrasonic instrumentation than hand instrumentation(P<0.005). 3. In the transportation width, there was not significant difference between the two groups at both sectioned levels(P>0.05). 4. It was suggested that the canal was transported distally at middle third level and mesially at apical third level by booth techniques.

  • Fuzzy controller design consists of intuition, and any other information about how to control system, into a set of rules. These rules can then be applied to the system. It is very important to decide parameters of IF-THEN rules. Because fuzzy controller can make more adequate force to the plant by means of parameter optimization, which is accomplished by learning procedure. In this paper, we apply fuzzy controller designed to the Swing-UP Inverted pendulum.
