As recent as 2015, MERS had outbreaks in South Korea, resulting in 36 deaths among 186 infected patients. The purpose of this thesis is to gain an in-depth understanding of how this viral infection behaves in outbreaks and how it is spread around the globe. To gain insight, real time analysis was performed under a case study methodology based on pooled data from the Ministry of Health & Welfare of South Korea. We calculated a striated mortality rate based on gender, age, and the presence of pre-existing health conditions ranging from heart, lung, and kidney diseases. We found that MERS outbreak follows the pattern of a point source outbreak, largely spurred by the patient-referral system under the universal healthcare system in South Korea. The purpose of this case is to discuss the benefits and challenges of such patient referral system, and to offer a possible solution in improving transparency between healthcare providers and the government under a universal healthcare system to prevent future outbreaks.展开更多

Data was collected from the registers. A total number of 1734 clients reported at family planning clinic of Monkey-Bay Community Hospital between January 2018 and June 2019. All the clients were females. Most of these clients were in the age range of 15 - 34 years (83.33%). There were 1,486 (87%) HIV negative clients, 208 (12%) HIV positive clients and 24 (1%) had unknown HIV status. Most clients had a parity of 1 - 2 (905, 52.71%) followed by 3 - 4 (540, 31.45%) and 5 or plus (272, 15.84%). There were more married people (1641, 97.23%) than unmarried ones (46, 2.73%). There was only one person who was divorced (1, 0.05%). Education status was not recorded. The five commonly used contraceptive methods were: Intramuscular (IM) injectable Depo-IM (1366, 79.51%), Jadelle (122, 7.10%), Subcutaneous (SC) injectable Depo-SC (65, 3.78%), Combined Oral Contraceptives (COC) (60, 3.49%) and Implanon (40, 2.33%). None of the clients was used female condoms as a method of contraception. The contraceptive use was common between the age group of 15 - 24 (707, 44.92%) and 25 - 34 (709, 45%). Depo-IM was most used in age group 25 - 34 (44.5%) while Jadelle was mostly used by 15 - 24 years old (48%). 1181 clients (79.5%) of HIV negative clients used Depo-IM as the contraceptive method while 164 clients (78.8%) of HIV positive clients used Depo IM as a method of contraception. More HIV negative clients used Jadelle and COC as compared to HIV positive clients. The choice of a particular method of contraception was influenced by many factors. Parity, marital status, age as well as HIV status did have some association with the preferred method of contraception. Our study shows that there could be varied reason for women chose types of contraception in this part of Malawi. Interventions that aim to increase access to family planning methods, should consider exploring the reasons why clients use some methods more than the other for better planning of these services. Absence of male clients accessing vasectomy at the hospital raises concern and more studies will be needed to determine the reason why men do not come forward for family planning services at Monkey Community Hospital.展开更多

Mediator-less two chamber H-type MFCs were prepared using rumen fluid as anode inocula to convert finely ground pine tree (Avicel) at 2% (w/v) to electricity. Dried Doraji roots were ground to pass 1 mm sieve and added to the anode of MFC at 0.1% w/v dosage for treatment. MFC power and current across an external resistor were measured daily for 10 d. At the end of incubation on d10, collected gases were measured for total gas volume and analyzed for gas composition on gas chromatography. Supplementation of Doraji roots powder to MFC anode chamber increased power generation and CO2 production. Over the 10d experimental period, power density normalized to anode surface 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 increased and methane to CO2 ratio decreased in Doraji root treatment comparing to control group. These observations imply that Doraji root components would inhibit methanogenesis and alter microbial fermentation of cellulose compounds favorable to produce bioenergy efficiently in MFC.展开更多
