잔류물질 간이 시험법으로 EEC-4 plate test와 Charm II test가 항생물질과 합성항균제 잔류검사에 널리 이용되고 있는 바, 이들 상호간의 결과 수치를 비교, 분석한 결과 다음과 같은 결론을 얻었다. EEC-4 plate혹은 Charm II 에서 양성으로 나타난 돈육 71건에 대하여 HPLC로 정량 분석한 결과, only tetracyclines 46건, only sulfonamides와 solfonamides+tetracyclines가 각각 4건씩, amphenicols+tetracyclines와 amphenicols+sulfonamides+tetracyclines가 각각 1건씩 검출되었고, 15건에서는 검출되지 않았다. Sulfonamides 계열에서 검출된 9건의 경우, Charm-II test 결과 수치가 낮은 경우에 정량 검출량이 높게 나타났고, EEC-4 plate test 결과 pH 6.0, pH 7.2, pH 8.0 모두에서 양성으로 나타나는 등 두 시험방법 간에 연관성이 있었고, chloramphenicols 계열에서 검출된 2건과 검출되지 않은 7건의 경우, Charm-II test결과 수치가 낮은 경우에는 오히려 정량 검출되지 않았으나, control point 근방의 양성 수치에서는 검출량이 높게 나타날 뿐 아니라 EEC-4 plate test에서도 pH6.0, pH7.2, pH8.0 모두에서 양성으로 나타나는 등 두 시험방법 간에 연관성이 있었다. 한편, tetracycline계열의 경우, EEC-4 plate와 Cham-II간에 연관성은 없었다. 또한, EEC-4 plate와 Charm II에서 각각 양성을 나타내었으나 HPLC에서는 검출되지 않는 경우는 tetracyclines계열에서는 $10.5\%(6/57)$, sulfonamides계열의 경우는 없었고, chloramphenicols계열의 경우는 $81.8\%(9/11)$로 각각 나타나 EEC-4 plate와 Charm II가 세 가지 잔류물질 시험에 대한 screening method로서 적합함을 알 수 있었다.

TFT-LCD panel makers have been enlarging size of TV screens, and 50-inch TFT-LCD is one of the main stream products already. To have more improved resolution, productivity and lower manufacturing cost, new TFT-LCD factories adopt large mother glass, new TFT structure and new process/materials. Along with these technology evolution, laser repair system should equip with upgraded performance and additional functions on user's demand. Laser repair technology is reviewed and newly developed repair technology is being introduced.

This study analyzed the factors affecting the effectiveness of the Chemical Hazard Risk Management (CHARM). A survey was conducted on 104 learners who participated in the Risk Assessment training course at Occupational Safety and Health Training Institute. Through a self-administered questionnaire, the effect of personal characteristics, corporate characteristics, and safety and health level of the company on the effectiveness of chemical risk assessment was investigated. As a result of statistical analysis, the safety and health level of the company had a positive (+) effect on the effectiveness of Chemical Hazard Risk Management(CHARM), but personal characteristics and corporate characteristics had no relation to it. This study can be used as basic data for further research related to chemical risk assessment in workplaces.

The European Economic Community four plate test(EEC 4-plate test, FPT, EU) has been used for monitoring antimicrobial drug residues in meat by Local Veterinary Service Center in Korea. This study was performed to evaluate sensitivity and group specificity of some antimicrobial drugs in FPT and to compare FPT with Charm II test. The minimal detectable levels of targeted antimicrobial drugs tested with standard solutions were 0.025∼1.0 ppm for 7 beta-lactams, 0.5∼1.0 ppm for 4 aminoglycosides, 0.05∼0.5 ppm for 5 macrolides, 0.05∼0.25 ppm for 3 tetracyclines and 0.25&1.0 ppm for 6 sulfonamides. In comparison of FPT and Charm II test, the results of FPT were not accord with those of Charm II test having the group specificity of seven families of antimicrobial drugs in meat samples except some families like tetracyclines.

This study was carried out to compare the residual antibiotic materials in muscles of slaughter cattle and swine from slaughterhouses in Seoul from 2000 to 2001 by EEC-4-plate method, Charm II and HPLC method. 1. Residual antibiotic materials were detected from 95 samples(0.8%) by EEC-4-plate and 57 samples(10.2%) by Charm II. The final HPLC method determined the positives are 43(45.3%) and 27(47.3%) respectively. 2. The detection ratios were 45% by EEC-4-plate and 47% by Charm II. 3. Seventy samples were classified as tetracyclines 56(75.7.4%), sulfonamides 10(14.9%), $\beta$-lactam 6(8.1%) chloramphenicol 1(1.4%). Three of them were confirmed to be positive simmultaneously for tetracyclines, sulfonamides and chloramphenicol. 4. The highest residual concentration of chlortetracycline, oxytetracycline, sulfamethazine, sulfadimethoxine, sulfaquinoxaline, penicillin, ampicillin and chloramphenicol were 0.34, 11.29, 68.16, 0.13, 4.0, 0.12, 0.4 and 0.04ppm, respectively.

The root extracts of Paeonia lactiflora cv. 'Red Charm' has been studied by many groups, however, little attention has been paid to its flower petal. Paeonia is the genus in the Paeoniaceae family. 'Red Charm' Paeonia is a soft-stemmed herbaceous peony hybrid of P. officinalis and P. lactiflora. We previously showed the flower petal extract of Red Charm might have anti-oxidant and anti-inflammatory activities, however, it was not clear which components might be involved in this activity. Bioinformatics analysis previously indicated these extracts have potential anti-oxidant materials. One of them is identified as paeoniflorin, which is major component in root extract of Red Charm. In this study, we compared paeoniflorin and oxypaeoniflorin using DPPH assays to measure its anti-oxidant activities. Oxypaeoniflorin showed higher levels of radical scavenging activity, similar to ascorbic acid control, whereas paeoniflorin did not. Furthermore, nitric oxide assay showed they have similar anti-inflammatory effects. Taken together, these results suggest oxypaeoniflorin may play a more important role in the anti-oxidant activity of the flower petal and root extracts of Red Charm, compared to paeoniflorin. Further studies may be able to provide a platform to develop potential dual effects therapeutics for oxidant-mediated and inflammation-mediated disease in the near future.

Recently, as concern about the residual antibiotics in milk increase, the detection methods of residual antibiotics used extensevely at the present time were investigated and compared to their properties and the detection limits of variable antibiotics. At first, comparactive tests of the detectable sensitivity of 4 test organisms, B. cereus, B. subtilis, M.luteus, B.stearothermophilus C-953, were performed by disc assay. As a result, B.stearothermophilus was the most sensitive strain of all other strains and showe the detect limit of 5-50 ppb for penlicillins (PCs). And also, B.subitilis was showed the more effective detection limit, 200-400 ppb, for aminoglycosides (AGs) and M.luteus was showed predominant sensitivity , 50-500 ppb for macrolides(MLs) and B.cereus was the most sensitive strain for tetracyclines (TCs) and showed the detection limit of 100-400 ppb. Therefore, each test strains were showed a different sensitivity in the detection of the different antibiotic families. When the detection limit of disc assay and other methods were compared, TTCmethod was less sensitive than other methods showing 5-50 ppb detectable lebel for PCs. Also, for the detection of other antibiotic families TTC method was showed the worst sensitivity and Delvo and Charm Farm tests were similar to the detectable properties of AGs and MLs. Although disc assay was showed the similar detection limit for PCs with Delvo and Charm Farm, it was more widely effective for the detection of kanamycin, erythromycin, chlortetracycline, doxycycline, verginiamycin and so on than Delvo or Charm Farm. CharmII test was showed the best sensitivity for the most of antibiotics except neomycin and gentamycin. But it was necessary that different tests must be performed to each antibiotic family and so it was regarded that the effectiveness of that method was low.
