  • This study was conducted to evaluate the modified drug sensitivity test for the shortening of detection time and clinical application. The results obtained were summarized as follows. 1. Inhibitory zone in 6 strains of Staphylococcus and Escherichia coli tested to sensitivity teat were reached at 100% between 2 and 6 hours. 2. The sensitivity test of Staphylococcus A, B and E. coli No. 2, No. 3 to antibacterial ointment drugs were strong positive(+++), but Staphylococcus A. A. and E. coli No. 1 were mild resistant(+). 3. The sensitivity test of Staphylococcus A. B and E. coli No. 2, No. 3 to antibacterial injection drugs in 6 hours after treatment were strong positive(+++), and Staphylococcus A. A. and E. coli No. 1 were moderate positive(++). 4. This modified method was detected 86% degree of sensitive between 7 to 12 hours after treatment. 5. We think this modified method was more practical compare to other methods.

  • Flame detectors has been used more than heat & smoke detector, because this is more effective to catch fire and ceiling height in spite of high price. For upgrade to flame detector, Compare to national or abroad standard about performance test, sensitivity test, sectioning indoor or outdoor, after service and management. As a result, Europe and America have only sensitivity test, no have not operation test and sectioning indoor & outdoor. In performance test, action is put to focus to credit and durability, Not operation test is to be able to tune the sensitivity to match the environment of the site. Also, we need code about aftercare, quality assurance responsibility and implement special detector institution by Certificate Authority implement.

  • Garlic (Allium sativum, L.) has a long history of reputed value and actual use for its medicinal, antimicrobial, and pesticidal properties. This study was conducted to find possible developments to natural food preservatives from garlic extracts. Garlic extracts were prepared from fresh crushed garlic and diluted with sterilize distilled water. The sensitivity test was conducted to investigate the antimicrobial effect of garlic extract against six strains of food poisoning bacteria such as Staphylococcus aureus, Escherichea coli, Salmonella typhimurium, Vibrio parahemolyticus, Bacillus subtilis, and Listeria monocytogenes. The results of sensitivity test were then compared with those of Vancomycin and Imipenem which were used as treatment for G. (+) bacteria and G. (-) bacteria, respectively. All of the 6 tested strains exhibited strong or moderate activity. V. parahemolyticus exhibited susceptible only in undiluted solution, but not in diluted garlic extracts.

  • PCR of the mecA gene for the rapid detection of methicillin-resistant staphylococci was perfomed and compared with the antibiotic sensitivity test. A total of 43 strains of staphylococi from clinical specimens were used in this study. An antibiotic sensitivity test by the agar dilution method of NCCLS (The National Commitee for Clinical Laboratory Standard) was performed for the strains. Among them, 39 isolates were methicillin-resistant (MRS), and 4 isolates were methicillin-susceptible (MSS). With the exception for one strain (Staphylococcus cohnii, HRC2-4), all MRS strains amplified the expected 533 bp fragments of the mecA gene by PCR, However, one strain (Staphylococcus aureus, HSA1-10) that was classified as a sensitive strain by the antibiotic sensitivity test was mecA positive by PCR. All 35 methicillin-resistant Staphylococcus aureus (MRSA) strains were mecA positive, but overall, concordance between the results of the mecA PCR and antibiotic sensitivity test was 95.6%.

  • Objectives : Although the thermo-sensitivity test in Well points in 12 Meridians(井穴知熱感度測定法) has been used for several decades, it is still performed by a manual way, and lack in objectivity consequently. To make it more objective, accurate and convenient test, we have developed a novel system to test thermo-sensitivity in Well points. Methods : To enhance the blindness of the test, we made a shielded system which give heat to some fingers of subjects in random way. To perform the test in quantitative manner, we developed a fully automated, computer-controlled system composed of heating bulbs and response button array. Results : The developed system showed linearity in heating the finger phantom. It also gave acceptable but interesting features in pilot tests with several young adult subjects. Conclusions : By the developed system, we could improve objectivity and convenience of the thermo-sensitivity test in Well points.

  • This paper studied the measurement about the gunpowder residue quantity by using a handgun and we carried out an experiment ignition characteristics of the gunpowder residue for the investigation fire cause into the indoor shooting range in Busan. The measurement of the gunpowder residue quantity is spouted by using a 0.38 inch gun and 9 mm gun. We were carried out evaluation experiments such as impact sensitivity test, static electricity sensitivity test, friction sensitivity test and measuring a flash point for the ignition characteristics about the gunpowder residue. From experiment results, the impact sensitivity and friction sensitivity of the gunpowder residue in comparison with ball powder are highly sensitive and the gunpowder residue ignites at a relatively low temperature.

  • The Oriental White Stork (Ciconia boyciana) is a representative wetland species distributed across East Asia. The species has been declined to face the threat of species extinctions with estimation of at about 3000 individuals. In order to re-introduce the endangered storks in the field, we developed a baseline model using the program VORTEX, performed sensitivity test, and finally suggested an ideal model based on results of the sensitivity test. The baseline model predicted 12.5% extinction probability with mean time to first extinction of 82.0 year. Sensitivity test revealed that two demographic variables (first-year mortality and percent of adult female breeding) had the greatest impacts on population persistence. Thus, corrected model improved the population persistence, where the extinction probability decreased to 1.0% in 100 years by changing values of two variables within a range of applicable to the population. Our models for stork re-introduction suggest this population will be stable by improving first-year mortality and adult female fecundity.

  • A Total of 173 streptococci isolated from 536 dairy cattle in Gyeonggi Province identified by Lancefield serological reaction and other biological properties. Antibiotics sensitivity test was also examined and the results obtained were as follows: 1. A total of 173 isolates of 167 strains (96.5%) were reacted with group A,B,C,D,E and G antisera. 2. Of the 167 positive strains, 75 strains were identified to Streptooccus uberis, 56 to Streptococcus agalactiage and 26 to Streptococcus dysgactiae, respectively. Also, Sreptococcus pyogenes, group D and group G streptococci were rarely isolated. 3. In results of antibiotic sensitivity tests, the most isolates were sensitive to leucomycin and erythromycin but less sensitive to streptomycin. and kanamycin.
