  • The voltage induced in the superconducting background magnet system is analyzed according to the calculation of self inductance and mutual inductance. The voltage induced by blip and compensation coils of the background magnet system is about 6.4V. In order to charge the main background magnet, the power supply must provide the minimum voltage of 1.1 kV. the compensation coils have an influence on the field distribution. The compensation coils result in the decreasing center field about 2.67%. It can remarkably decrease the ac losses and the voltage on the current leads of the background magnet.

  • Significant advances in computational performance have occurred over the past two decades, achieved not only by the introduction of more powerful processors but the incorporation of parallelism in computer hardware at all levels. Simultaneous with these hardware and associated system software advances have been advances in modeling physical phenomena and the numerical algorithms to allow their usage in simulation. This paper presents a review of the advances in computer performance, discusses the modeling and simulation capabilities required to address the multi-physics and multi-scale phenomena applicable to a nuclear reactor core simulator, and present examples of relevant physics simulation codes' performances on high performance computers.

  • Over the past 40 years, flow cytometry has emerged as a leading, application-rich technology that supports high-resolution characterization of individual cells which function in complex cellular networks such as the immune system. This brief overview highlights advances in multiparameter flow cytometric technologies and reagent applications for characterization and functional analysis of cells modulating the immune network. These advances significantly support highthroughput and high-content analyses and enable an integrated understanding of the cellular and molecular interactions that underlie complex biological systems.

  • Recent advances in bronchoscopy have led to changes in clinical diagnostics and therapeutics in pulmonary medicine. In diagnostic bronchoscopy, there have also been new developments in endobronchial ultrasound technology which may be incorporated into clinical practice in the near future. Functional bronchoscopy, which evaluates information such as airway pressure, airflow, or gas exchange, suggests promising clinical advances in the near future. In therapeutic bronchoscopy, bronchoscopic volume reduction is a novel approach for the treatment of severe emphysema. In this review, seven recently published articles representing current advances in bronchoscopy are summarized and discussed.

  • The stability of PF 6-7 has been studied according to the transient analysis code TOKSCPF and quench analysis code QSAIT. We compare the stability and temperature rise with various Cu/SC ratios of 2.8 and 3.5 under the KSTAR normal operating conditions. It shows that the Cu/SC ratio has an influence on the quench propagation and stability margin. In transient operating condition, the Cu/SC ratio weakly influences on the temperature rise in PF magnet.

  • 석탄가스화 기술은 청정석탄에너지 기술 중에서 아주 중요한 대안으로 인식되고 있으며, 이에 전 세계적으로 차세대 석탄가스화기라고 할 수 있는 고효율 저비용 석탄가스화기를 개발하고 있다. 본 연구에서도 이러한 목적의 달성을 위하여 저비용으로 구현이 가능한 컴팩트 석탄가스화기를 개발하고 있으며, 다수개의 공급부로 이루어진 일체형 이중선회형 버너를 개발하였다. 개발된 버너의 가스화 운전조건을 확보하기 위하여 미분탄 분배기와 함께 기존의 석탄가스화기 몸체에 설치하여 가스화 실험을 수행하였다. 인도네시아산 아역청탄인 ABK 탄을 사용하여 1.5톤/일의 파일럿 규모로 $6.4{\sim}7.2kg/cm^2$, $1170{\sim}1300^{\circ}C$ 조건에서 운전을 수행하였다. 우선 성능평가보다는 안정적인 가스화기 운전조건을 확보하는데 중점을 두었다. 그 결과, 안정적인 운전조건에서 탄소전환율은 84.0%, 냉가스 효율 52.1%를 확보할 수 있었다.

  • Interest in process control has rebounded from an all-time low in the mid-1970s, with a new focus on bridging the gap between academic theory and industrial practice. Since then, much progress has been made in the new generation of process control theory to bridge this gap. This review summarizes the recent advances and cur-rent problems in process control on a qualitative level.
