        Sustainable Energy Options

        ( Andrew Blakers ) 경남대학교 극동문제연구소 2015 ASIAN PERSPECTIVE Vol.39 No.4

        Solar energy is special: It is vast, ubiquitous, and indefinitely sustainable. The solar resource is much larger than all other available energy resources combined. Solar energy utilizes very common materials; has minimal security and military risks; is available nearly everywhere in vast quantities; and has minimal environmental impact over unlimited time scales. The recent (and continuing) rapid price reduction in photovoltaics and wind energy was not generally foreseen, and is likely to lead to widespread market disruption. New wind and solar photovoltaic (PV) systems are both being deployed around the world in similar scale to new coal, gas, and hydro systems. Renewable energy now constitutes the majority of new generation capacity installed each year. Electricity from wind and PV systems is now cost-competitive with newly built coal, gas, oil, and nuclear generators in many parts of the world. Roof-mounted PV systems successfully compete with conventional gas and electricity for the supply of heat and electricity in cities. Transport and chemical synthesis powered by PV and wind electricity is likely to be competitive in the future.

        Antenatal Thyroid Function Does Not Increase Risk of Gestational Diabetes Mellitus in a Multi-Ethnic Pregnancy Cohort

        Christopher Alan Muir,Ashish Munsif,Kenrick Blaker,Yvonne Feng,Mario D’Souza,Shailja Tewari 대한갑상선학회 2020 International Journal of Thyroidology Vol.13 No.1

        Background and Objectives: Subclinical hypothyroidism in pregnancy has been inconsistently associated with an increased risk of developing gestational diabetes mellitus (GDM). Materials and Methods: We retrospectively examined whether an antenatal thyroid stimulating hormone (TSH) level ≥2.5 mIU/L was associated with increased risk of GDM in 1147 pregnant women residing in a multi-ethnic suburban area of Sydney, Australia. Results: Despite a high prevalence of GDM and hypothyroidism in our study, women with antenatal TSH concentrations ≥2.5 mIU/L were not at increased risk for development of gestational diabetes. Traditional risk factors for GDM, such as maternal body mass index, ethnicity, previous GDM pregnancy and family history of type 2 diabetes were significant predictors of incident GDM on multivariable analyses. Conclusion: Mild elevations in antenatal TSH concentration did not significantly increase risk of incident GDM compared to healthy euthyroid women.
