The current s.udy reports.the evidence of enhancement in power generation from cellulos.c biomas. in microbial fuel cell (MFC) s.s.ems.by s.pplementing dried Doraji (Platycodon grandiflorum) roots.powder. Mediator-les. two chamber H-type MFCs.were prepared us.ng rumen fluid as.anode inocula to convert finely ground pine tree (Avicel) at 2% (w/v) to electricity. Dried Doraji roots.were ground to pas. 1 mm s.eve and added to the anode of MFC at 0.1% w/v dos.ge for treatment. MFC power and current acros. an external res.s.or were meas.red daily for 10 d. At the end of incubation on d10, collected gas.s.were meas.red for total gas.volume and analyzed for gas.compos.tion on gas.chromatography. s.pplementation of Doraji roots.powder to MFC anode chamber increas.d power generation and CO2 production. Over the 10d experimental period, power dens.ty normalized to anode s.rface area were between 17.0 and 37.7 with average of 32.5 mW/m2 in Doraji MFCs. and between 16.8 and 19.8 with average of 18.2 mW/m2 in control group. CO2 production increas.d and methane to CO2 ratio decreas.d in Doraji root treatment comparing to control group. Thes. obs.rvations.imply that Doraji root components.would inhibit methanogenes.s.and alter microbial fermentation of cellulos. compounds.favorable to produce bioenergy efficiently in MFC.

The Middle Eas. Res.iratory s.ndrome (MERs.CoV) is.a potentially fatal res.iratory viral infection that has.had outbreaks.in the Middle Eas. and As.a region s.arting in 2012. As.recent as.2015, MERs.had outbreaks.in s.uth Korea, res.lting in 36 deaths.among 186 infected patients. The purpos. of this.thes.s.is.to gain an in-depth unders.anding of how this.viral infection behaves.in outbreaks.and how it is.s.read around the globe. To gain ins.ght, real time analys.s.was.performed under a cas. s.udy methodology bas.d on pooled data from the Minis.ry of Health & Welfare of s.uth Korea. We calculated a s.riated mortality rate bas.d on gender, age, and the pres.nce of pre-exis.ing health conditions.ranging from heart, lung, and kidney dis.as.s. We found that MERs.outbreak follows.the pattern of a point s.urce outbreak, largely s.urred by the patient-referral s.s.em under the univers.l healthcare s.s.em in s.uth Korea. The purpos. of this.cas. is.to dis.us. the benefits.and challenges.of s.ch patient referral s.s.em, and to offer a pos.ible s.lution in improving trans.arency between healthcare providers.and the government under a univers.l healthcare s.s.em to prevent future outbreaks.
