Twelve new benzothiazolyl-and N-6-carbomethoxy, ethoxybenzothiazolyl-N'-phenylureas have been synthesized by reacting 2-aminobenzothiazole and 2-amino-6-carbomethoxy, ethoxybenzothiazole with three or four phenyl and chlorophenyl isocyanate, respectively. The structures of these compounds were determined by the elementary analysis, UV spectrophotometry, NMR and IR spectrophotometry. Antimicrobial activities of the synthesized compounds were, in vitro, examined against Escherichia coli APCC 25922, Shigella flexneri NIH, Salmonella typhi H 901, Staphylococcus aureus APCC 65389 and Sarciana lutea APCC 9341. The compounds generally exhibited antibacterial activity against Gram negative bacteria in concentration of 500mcg/㎖. The compounds containing carbomethoxy group exhibited stronger antibacterial activity than those containing carboethoxy group against Salmonella typhi. The compounds containing m-chlorophenyl groups, on the whole, exhibited more potent growth-inhibitory activity against Shigllea flexneri and Salmonella typhi.

본 논문에서는 기존 GPS 수신기용으로 설계된 상용 칩셋을 이용하여 GLONASS 수신기를 설계하고 구현 결과를 살펴본다. 설계한 수신기는 GPS에 비해 넓어진 주파수 대역 처리를 위하여 RF 처리부 구조를 변경하였고, FDMA를 사용하는GLONASS 신호 처리를 위해서 FPGA를 이용하여 신호분리기를 설계하였다. 마지막으로 항법해를 구하기 위해 최소 자승법을 이용하였다.

2-Substituted benzimdazoles were prepared by reacting o-phenylenediamine with acid chlorides, which has advantages over the known synthetic procedures. The compounds prepared showed no significant antiinflammatory activity, thus are of no interest as antiinflammatory agents.

This paper describes a Forward Collision Warning (FCW) system based on the radar driven fusion with camera. The objective of FCW system is to provide an appropriate alert with satisfying the evaluation scenarios of US-NCAP and a driver acceptance. For this purpose, this paper proposed a data fusion algorithm and a collision warning algorithm. The data fusion algorithm generates information of fusion target depending on the confidence of camera sensor. The collision warning algorithm calculates indexes and determines an appropriate alert-timing by using analysis results of manual driving data. The FCW system with the proposed data fusion and collision warning algorithm was investigated via scenarios of US-NCAP and a real-road driving. It is shown that the proposed FCW system can improve the accuracy of an alarm-timing and reduce the false alarm in real roads.

This paper presents methods of robot localization using recent Radio Frequency Identification technology. If the absolute location and orientation of a passive tag are given in indoor environment which is installed RFID tags, a robot can estimate its location using the relationship of identified tag and robot in relative coordinate. To derive this relationship, we proposes estimation techniques using the probabilistic model of RFID reader, the direction and the maximum range of identification. And condition-processor is combined in a suitable technique depending on the situation and the trajectory of robot in the field of range. Experimental results show that the proposed methods can provide good performance and thus be used for localization.

This paper presents a longitudinal control strategy for an Adaptive Cruise Control (ACC) with Collision Avoidance (CA) in multiple transitions by a driver and traffic conditions. The objective is for smooth and safe transition between various driving situations to achieve driver’s comfort and prevention of collision. The proposed control strategy consists of a multi-target tracking filter, a primary target selection algorithm and a longitudinal ACC/CA controller. The multi-target tracking filter is used to smooth the sensor signal, and makes it possible to apply to a control system. The primary target selection algorithm decides an important target which has an effect on the subject vehicle. In addition, it provides the information to a longitudinal ACC/CA controller in order to drive a subject vehicle smoothly and improve safety in various traffic transitions. Finally, the longitudinal ACC/CA controller computes the desired acceleration. The performance and safety benefits of the multi-vehicle ACC/CA system is investigated via simulations using real data on driving. Simulation results show that the response of multi-vehicle ACC/CA system is more smooth and safer in multiple transitions.
