Update on Procalcitonin Measurements
Michael Meisner 대한진단검사의학회 2014 Annals of Laboratory Medicine Vol.34 No.4
Procalcitonin (PCT) is used as a biomarker for the diagnosis of sepsis, severe sepsis and septic shock. At the same time, PCT has also been used to guide antibiotic therapy. This review outlines the main indications for PCT measurement and points out possible pitfalls. The classic indications for PCT measurement are: (i) confirmation or exclusion of diagno- sis of sepsis, severe sepsis, or septic shock, (ii) severity assessment and follow up of sys- temic inflammation mainly induced by microbial infection, and (iii) individual, patient adapted guide of antibiotic therapy and focus treatment. Using serially monitored PCT lev- els, the duration and need of antibiotic therapy can be better adapted to the individual re- quirements of the patient. This individualized approach has been evaluated in various studies, and it is recommended to be a part of an antibiotic stewardship program.
Public Disclosure of Environmental Violations in the Republic of Korea
Hong, Jong-Ho,Laplante, Benoit,Meisner, Craig 한양대학교 경제연구소 2003 경제연구 Vol.24 No.2
Since 1989, environmental authorities of South Korea have published on a monthly basis a list of enterprises violating the country's environmental rules and regulations. This may be the longest environmental public disclosure program currently in existence. Over the period 1993-2001, in excess of 7,000 violation events have been recorded on these monthly violation lists, involving more than 3,400 different companies. In this paper, we provide a comprehensive descriptive analysis of this dataset. Results suggest that the news media has given an important, though perhaps declining coverage to the violation lists, with a focus on publicly traded companies, failures to operate pollution abatement equipment, and prosecutions.

최근 실효성 있는 환경규제 정책으로서 정보유인수단(information-based incentives)에 대한 관심이 높다. 1989년 이래 우리나라 환경부는 각종 환경규제 법령을 위반한 업체들에 관한 정보를 매달 보도자료의 형태로 공개하고 있다. 그 정보의 내용과 특성에 비추어 볼 때 매우 광범위하고 자세한 자료를 축적하고 있다고 할 수 있다. 본 연구는 1992년부터 2002년에 걸쳐 3,400개 이상의 업체에서 발생한 7,000건 이상의 위반사항, 지역, 정부조치, 언론보도 등에 대한 분석을 목적으로 한다. 분석 결과, 상장기업 위반 건수가 차지하는 비중은 전체의 16.8%이나 언론보도 비중은 40%에 달함으로써 상장기업의 환경성과에 대한 언론매체의 관심을 반영하고 있는 것으로 나타났다. 또한 위반내역에 있어서는 배출허용 기준초과와 방지시설의 비정상가동이, 그리고 조치내용에 있어서는 개선명령과 고발에 대해 많은 언론보도가 있었음을 확인하였다.

CARMA LARGE AREA STAR FORMATION SURVEY: DENSE GAS IN THE YOUNG L1451 REGION OF PERSEUS
Storm, Shaye,Mundy, Lee G.,Lee, Katherine I.,Ferná,ndez-Ló,pez, Manuel,Looney, Leslie W.,Teuben, Peter,Arce, Hé,ctor G.,Rosolowsky, Erik W.,Meisner, Aaron M.,Isella, Andrea,Kauffmann American Astronomical Society 2016 The Astrophysical journal Vol.830 No.2
<P>We present a 3 mm spectral line and continuum survey of L1451 in the Perseus Molecular Cloud. These observations are from the CARMA Large Area Star Formation Survey (CLASSy), which also imaged Barnard. 1, NGC 1333, Serpens Main, and Serpens South. L1451 is the survey region with the lowest level of star formation activity-it contains no confirmed protostars. HCO+, HCN, and N2H+ (J = 1 -> 0). are all detected throughout the region, with HCO+ being the most spatially widespread, and molecular emission seen toward 90% of the area above N(H-2) column densities of 1.9 x 10(21) cm(-2). HCO+ has the broadest velocity dispersion, near 0.3 km s(-1) on average, compared with similar to 0.15 km s(-1) for the other molecules, thus representing a range of subsonic to supersonic gas motions. Our non-binary dendrogram analysis reveals that the dense gas traced by each molecule has a similar hierarchical structure, and that gas surrounding the candidate first hydrostatic core (FHSC), L1451-mm, and other previously detected single-dish continuum clumps has similar hierarchical structure; this suggests that different subregions of L1451 are fragmenting on the pathway to forming young stars. We determined that the three-dimensional morphology of the largest detectable dense-gas structures was relatively ellipsoidal compared with other CLASSy regions, which appeared more flattened at the largest scales. A virial analysis shows that the most centrally condensed dust structures are likely unstable against collapse. Additionally, we identify a new spherical, centrally condensed N2H+ feature that could be a new FHSC candidate. The overall results suggest that L1451 is a young region starting to form its generation of stars within turbulent, hierarchical structures.</P>
