The purpose of this study was to compare the effect of the traditional instruction with that of the systematic instruction upon the concepts and principles learning in engineering students. Mainly the traditional instruction was sequenced according to the "logic" of the content. The traditional instruction groups were divided into two groups-lecture group and sound slides group which have proceeded the same insttuctional events. The systematic instruction was sequenced according to the learner characteristics, learning tasks, and media characteristics. The results of the present study showed that the research hypotheses were generally accepted. The systematic instruction group scored significantly greater than the traditional instruction groups (lecture group and sound slilds group) in the achievement test. Through the attitude and response test, it showed that the systematic instruction was more effective than the traditional instruction on the short-term memory and understanding and applying the concepts and principles. Almost every student attended this experiment wanted to use of instructional media on other units of foundary engineering and other subjects.

Vitek system, a fully automated in vitro testing system designed for identification and antimicrobial susceptibility test of microorganisms was introduced to The Seoul National University Hospital in 1985. Principal advantages of using this system are rapid identification of microorganisms and rapid reporting of the minimal inhibitory concentration values. Using Vitek system, 248 isolates from culture requested blood specimen in our hospital from April 11. 1991 to August 31. 1991 were identified and minimal inhibitory concentration test were performed. We summarized the data and obtained results as below. 1. 52.3% of catalase +, Gram ( +) cocci, 75% of catalase(-), Gram(+) cocci, 74.8% of Gram (-) glucose fermenters and 57.1% of glucose nonf ermenters were identified within 9 hour. 2. Mic values of 87.6% of Gram ( +) cocci ( catalase +,- ) and 86.6% of Gram ( - ) rods (glucose fermenters and nonfermenters) were obtained within 9 hour. 3. 32.5% of isolated organisms were reported within the test performed day by using Vitek system.
