In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
First Year Observations of Air Quality from Geostationary Environment Monitoring Spectrometer (GEMS)
Jhoon Kim,Dongwon Lee 한국대기환경학회 2021 한국대기환경학회 학술대회논문집 Vol.2021 No.10
Hourly observations of air quality (AQ) over Asia have been available by the Geostationary Environment Monitoring Spectrometer (GEMS) for the first time from a geostationary Earth orbit (GEO) since its launch in February 2020. After 8-month in orbit tests, the first light images were released in November, 2020. GEMS has observed diurnal variations of column amounts of atmospheric pollutants (O₃, NO₂, SO₂, HCHO, CHOCHO, and aerosols) with the UV-Vis spectrometer at 0.6 nm spectral resolution and sophisticated retrieval algorithms. Details of the first year of GEMS mission are presented, including calibrations, results, validations, and case studies including volcanic eruption, dusts, and urban pollution. The Advanced Meteorological Imager (AMI), Geostationary Ocean Color Imager 2 (GOCI-2), and GEMS can now provide synergistic science products to better understand air quality, the long-range transport of air pollutants, emission source distributions, and chemical processes. Faster sampling rates at higher spatial resolution increase the probability of finding cloud-free pixels, leading to more observations of aerosols and trace gases than LEO. GEMS will be joined by NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) and ESA’s Sentinel-4 to form a GEO AQ satellite constellation in 2022 and 2023, respectively, as recognized by the Committee on Earth Observation Satellites (CEOS).
