This study was carried out for the purpose of investigating the β-lactamase producing rates using acidimetric assay and disc method. Also, the author evaluated the drug resistance of ,β-lactamase producing staphylocci isolated from 34 patients in Chungnam National University Hospital and 25 medical students in Chungnam National University by antibiotic susceptibility test. The author sconducted the survey from January to June 1985. The results obtained were as follows: 1. Out of the 34 specimens from patients, Staphylococcus aureus isolated from pus and throat were 58.8% and 17.6%, respectively. 2. The β-lactamase producing rates of staphylococci isolated from patients and control groups using acidimetric assay after 1 year were 88. 2% and 84. 0%, respectively. 3. In the disc method and acidimetric assay, the (β-lactamase producing rates of staphylococci isolated from patients and control groups were 91.2%, 88.2% and 88.0%, 84. 0%, respectively. 4. The rates of resistance for penicillin among p-lactamase producing strains of staphylococci isolated from patients and control groups were 91.2% and 60.0%, respectively. 5. Out of the β-lactamase producing staphylococci isolated from patients and control groups, 88. 2% and 56. 0% were resistant to penicillin but sensitive to cephalothin.

The purposes of this study are to examine how Science Performance Assesment is being well conducted in elementary schools and to check the teachers' awareness through surveying the actual condition. To achieve this purpose, the author, in this study, distributed questionnaire developed by researcher under supervision of academic advisor to the elementary school teachers in Gyeongnam province. Based on the data. the research results were mainly analyzed by the statistical method using Chi-square test. The survey was consisted of questions which was designed to perceive teachers' awareness about elementary school science performance assessment. The main findings of this study are summarized as follows', 1. Elementary teacher's are doing affirmative estimation about induction of performance assessment. 2. Most teacher are recognizing performance assessment right and teachers' understanding appeared high. 3. Material development of performance assessment is recognizing that people who have opinion which is special must develop. 4. The biggest problem of performance assessment fixing is recognizing that number of persons per class are many and amount of training courses is much also with the tribe during time. 5. It was recognizing positively whether it is in class improvement of performance assessment effect. 6. Teachers had awareness that confirm studies accomplishment degree through performance assessment, or will utilize to improvement material of teaching-learning method.
