다수의 서보모터를 효과적으로 제어하기 위하여 I2C(Inter-Integrated Circuit)통신을 이용하는 네트워크기반의 서보모터에 적합한 프로토콜의 시퀀스를 설계하고 이에 대한 성능을 분석 및 실험 하였다. 그 결과 다수의 서보 모터로 구성된 네트워크 통신은 데이터 손실 없이 안정적인 통신이 이루어지고 원활하게 서보모터가 제어되는 것을 확인하였다.

The purpose of this study was to evaluate the efficiency of the four obturation techniques. In this study, eighty teeth were instrumented and randomly divided into 4 groups of 20 teeth each, according to the obturation techniques Group A was used with Microseal. in Group B, Thermafil. in Group C, continuous wave techniques, in Group D cold lateral condensation methods were used. After obturation, the teeth were taken a digital radiograph in mesiodistal and buccolingual directions to study the quality of the obturation.(omitted)

Maxillary first molar, the "6-year molar", is the tooth largest in volume and most complex in root and root canal anatomy. Therefore, maxillary first molar is possibly the most treated, least understood. It is the posterior tooth with the highest endodontic failure rate and unquestionably one of the most important teeth. The earliest permanent posterior tooth to erupt, the mandibular first molar seems to be the most frequently in need of endodontic treatment.(omitted)

Experimental study in coflow jet flames has been conducted to investigate the effects of adding $N_2$, $CO_2$ and He to coflowing air-side in self-excitations. Differences in the behaviors between buoyancy-driven and diffusive-thermal self-excitations with similar frequency range are explored and discussed in laminar coflow jet flames.

The Turbinellidae shell Columbarium pagoda pagoda (Lesson, 1834), from the southern coast of Korea was recorded as new to the Korean molluscan fauna. The shell is typically solid and fusiform, with a well elongated spire and long anterior canal, and keel with a row developed spine. The protoconch is small, planorboid to depressed dome-shaped. The family Turbinellidae is reported from Korea for the first time.

I. Objectives This study investigated the quantity of debris which was extruded apically after canal instrumentation using different types of enlarging instrument in endodontic resin models. II. Materials and Methods Five groups of 9 endodontic resin model were instrumented using each different technique：hand instrumentation without early coronal flaring, hand instrumentation after early coronal flaring, and three nickel-titanium engine-driven instrumentations(Hero 642, Protaper, K3) after early coronal flaring.(omitted)
