Objective: To evaluate the COVID-19 vaccination status and related characteristics of Turkish healthcare workers practicing chest ***: A cross-sectional online survey was conducted among the Turkish Thoracic Society members. The survey was started on May 17, 2021, and kept open for seven weeks. The 39-item survey included the COVID-19 vaccination status and demographic, clinical, and occupational characteristics. results: Of 378 healthcare workers participated in the survey, 354(93.7%) reported receiving at least one dose of the COVID-19 vaccine. A total of 323(91.2%) healthcare workers received CoronaVac vs. BioNTech/Pfizer in 31(8.8%). In the CoronaVac group, 77(23.8%) contracted COVID-19 when not fully vaccinated, and 13(4.0%) when fully vaccinated;however, 16(51.6%) healthcare workers in the BioNTech/Pfizer group got COVID-19 when not fully vaccinated, but any fully vaccinated participants did not contract COVID-19(P=0.003). regarding vaccine dosing, 328(86.8%) were fully vaccinated, while 50(13.2%) were not. Multiple regression analysis for being a non-fully vaccinated healthcare worker demonstrated a significant relationship with having any SArS-CoV-2 infection history(adjusted Or 9.57, 95% CI 3.93-23.26, Png a non-physician healthcare worker(adjusted Or 5.86, 95% CI 2.11-16.26, P=0.001), but a significant negative relationship with full-time working at the time of survey(adjusted Or 0.13, 95% CI 0.03-0.56, P=0.006). Conclusions: Although a majority of healthcare workers were fully vaccinated, occupational and non-occupational characteristics were related to being non-fully vaccinated. Active surveillance regarding the COVID-19 vaccination in healthcare workers is necessary to address specific parameters as barriers to vaccination.

SYNTHESIS AND CHArACTErIZATION OF A METHACrYLATE POLYMEr WITH SIDE CHAIN KETONE AND ITS DErIVATIVES

Chinese Journal of Polymer Science 2011年第1期29卷 101-110页

A new type of methacrylate monomer, 2-（4-benzoylphenoxy）-2-oxoethyl methylacrylate （BOEMA） was synthesized. The radical homopolymerization of BOEMA was performed at 65℃ in a 1,4-dioxane solution with benzoyl peroxide as an initiator. The oxime and thiosemicarbazone derivatives of poly[2-（4-benzoylphenoxy）-2-oxoethyl methylacrylate] poly（BOEMA） were prepared with hydroxylamine hydrochloride, and thiosemicarbazone hydrochloride, respectively. The monomer and its homopolymer were characterized with Fourier transform infrared and NMr techniques. The thermal stabilities of poly（BOEMA） and its derivatives were investigated with thermogravimetric analysis and differential scanning calorimetry. The ultraviolet stability of the polymers was compared. The antibacterial and antifungal effects of the monomer and the polymer and its derivatives were also investigated on various bacteria and fungi. The activation energies of the thermal degradation of the polymers were calculated with the Ozawa and Kissinger methods.
