  • Ten phosphate corrosion inhibitors meet the required standards and drinking waters containing corrosion inhibitors also within 27 items of water quality standards. In addition, the T-P concentration was observed at a level of 2.342-2.909mg/L. Those results indicate that the corrosion inhibitors are not harmful and, as for drinking waters with inhibitors, they can be considered not to have any toxic influence on human body when used below the regulated level of 10mg/L.

  • This study deals with technology planning-based management for Basic R&D Programs of government supported research institutes (GRIs). The Korean Research Council for Industrial Science and Technology which consists of major GRIs needs to implement new government policies which focus on the dissemination of R&D outcome, collaborative research, and performance-oriented R&D investment. The major characteristics of technology planning-based management include the hierarchy of market-oriented technology plans and the valuation of core technologies. We also suggest technology classifications and project network diagrams.

  • Botulism in wild waterfowl has been reported in many areas of the world. In 18 October 2008 to 22, 101 dead wild ducks were found in Anyangcheon. 24 of dead birds were spotbill (Anas poeilorhyncha), 56 were Mallard (Anas platyrhynchos), 18 were green- winged teal (Anas carolinensis) and 3 were others. Clinical sign of the sick birds were flaccid paralysis of the neck. At autopsy, most birds had no specific lesions. Stomach is empty. In the mouse bioassay, Samples of serum and intestinal contents taken from 9 dead birds killed all the injected mice, and their toxicity was neutralized by the antitoxin against C. botulinum type C toxin.

  • The antimicrobial susceptibility of 73 strains of Staphylococcus aureus isolated from dogs and cats was determined against 16 antimicrobial agents. All isolates were susceptible to cephalothin (CF), vancomycin (VA), rifampin (RA), quinupristin-dalfopristin (SYN) and linezolid (LZD), whereas more than 86.3% of the isolates were resistant to penicillin (P). In the case of enterotoxin production, 8.2% of 73 strains produced enterotoxin A and 1 strain produced enterotoxin C. Appropriate protocols for antimicrobial agents and strategies to reduce antimicrobial resistance will need to be investigated in the future.

  • This study was carried out to investigate the content of sulfur dioxide residues in the medicine prepared from crue drugs. Total 29 pills that contains salvia miltiorrhiza root, anemarrhena rhizome, fritillaria bulb, glehnia root, asparagus tuber, lycium fruit, moutan root bark, cimicifuga rhizome, pinellia tuber, dipsaci radix, codonopsis pilosula root, liriope tuber, achyranthes root, prepared aconite, aurantii fructus immaturus, corydalis tuber, dioscorea rhizome were examined by the modified Monier_Willams method. Sulfur dioxide were detectd in all the tested samples, and were found over MRLs (30 mg/ kg to medicinal herbs) in 8 samples (27.6%). Especilly, "i2" pills contains 132.46 mg/kg sulfur dioxide that is 4 times over than MRLs.

  • 2008년 국민건강영양조사에서 서울시민의 연령별 채소섭취량을 산정하여 2007년부터 2009년까지 서울지역에서 유통 중인 채소류에 대한 잔류 농약을 모니터링 하여 채소류섭취에 따른 연령별 농약성분의 노출량을 평가하였다. 서울시민에 대해 연령별 평균 채소류 섭취량을 분석한 결과 통계적으로 유의한 차이가 있었다(p<0.001). 연령그룹 중 40~59세 그룹의 채소류 섭취량이 가장 높게 나타났고 5세 이하 그룹의 채소류 섭취량이 가장 낮게 나타났다. 2007년부터 2009년까지 채소류 섭취에 따른 연령별 잔류농약의 %ADI(Acceptable Daily Intake)는 모두 1 이하로 나타나 잔류농약으로 인한 위해 가능성은 낮을 것으로 판단된다.

  • We investigated springs in Seoul in 2009 to know the change of water quality according to storage method of spring water, the concentration of chemical compounds and their correlation. Even spring water that originally satisfied national standard for drinking water could be exceeded national standard for drinking water by storage method such as storage bottle, temperature and period; especially used PET bottles could affect the increase of total colony counts. Therefore, spring water is desirable to be consumed on the spot, or to be stored in sterilized bottles in refrigerator rather than room temperature at home, and also to be consumed shortly not exceeding 24 hours. Total colony counts, coliform, yersinia, $F^-$, $Cl^-$, $NO_3^--N$, hardness, total Solids, pH, color and Al were exceeded national standard for drinking water at some springs. The result of correlation analysis shows that hardness and total solids, which are caused by several ionic compounds, had relatively high correlations with other chemical compounds.

  • 본 연구에서는 식품에서의 L. monocytogenes에 대한 기초자료를 제공하고자 2010년부터 2011년까지 서울지역에서 수거된 식품 총 1042건에서 L. monocytogenes를 분리하여 항생제 감수성 검사를 하였다. 김밥 4건(0.8%), 육회 4건(2.6%), 연어제품 2건(11.1%), 돈육식품과 조리된 생선에서 각 1건씩(각5.9%, 6.3%) 총 12균주가 분리 동정되었다. 분리 균주를 20종의 항생제에 검사한 결과 대다수 항생제(16종)에 감수성을 나타내었지만 cefotetan (11균주), cefotaxime (7균주), cefepime (6균주)에서 내성을 나타냈으며 3균주에서 임상치료에 자주 사용되는 tetracycline에 대해서 내성을 나타내었다.

  • Purpose: This study was conducted to identify indoor air quality in various living spaces using sensors that can measure noise, vibration, fine dust, and odor in real time and to propose optimal indoor air quality maintenance management using Internet of Things(IoT). Research design, data and methodology: Using real-time sensors to monitor physical factors and environmental air pollutants that affect the comfort of the residential environment, Noise, Vibration, Atmospheric Pressure, Blue Light, Formaldehyde, Hydrogen Sulfide, Illumination, Temperature, Ozone, PM10, Aldehyde, Amine, LVOCs and TVOCs were measured. It were measured every 1 seconds from 4 offices and 4 stores on a small scale from November 2018 to January 2019. Results: The difference between illuminance and blue light for each measuring point was found to depend on lighting time, and the ratio of blue light in total illumination was 0.358 ~ 0.393. Formaldehyde and hydrogen sulphide were found to be higher than those that temporarily attract people in an indoor office space that is constantly active, requiring office air ventilation. The noise was found to be 50dB higher than the office WHO recommendation noise level of 35 ~ 40dB. The most important factors for indoor environmental quality were temperature> humidity> illumination> blue light in turn. Conclusions: Various factors that determine the comfort of indoor living space can be measured with real-time sensors. Further, it is judged that the use of IoT can help maintain indoor air quality comfortably.
