Subject. The article discusses medical and demographic processes in Russia and Finland. Objectives. I evaluate cases of social innovations implemented for the preservation and strengthening of public health in Finland under the auspices of The Global Burden of Disease Study. Methods. Methodologically, the study relies upon the ideology of the GDB Project, which rests on the DALY (the Disability Adjusted Life Year). Results. I analyzed the morbidity and mortality rates, DALY in Russia and Finland, determined what mainly triggers the risk (environmental, behavioral, metabolic) fueling some public health degradation. The article provides the insight into the efficiency of some social innovations implemented in Finland and suggests what should be done to outline medical and demographic programs in Russia. Conclusions and Relevance. The medical and demographic situation in Russia requires new tools to find innovative solutions for the social policy and, inter alia, the use of the GBD technique, which proved to be effective. Referring to evidence from Finland, demographic challenges in Russian can be handled through a systems approach, i.e. socio-economic actions, improvement of the healthcare and social security, wellness propaganda.

Subject. This study focuses on the Finno-Ugric peoples carrying unique cultural customs and traditions. Objectives. I evaluate how various factors influence the demographic development of the Finno-Ugric peoples. Methods. Analyzing the current situation, I refer to official statistics and the Health for All database of the World Health Organization, statistical yearbooks of the Russian State Statistics Service. All data were organized as a special information system including several related blocks, such as economic development of locations, demographic situation, health and healthcare. Research was based on the comparative analysis of key medical-demographic and socio-economic indicators, and economic-mathematical apparatus. Results. I comprehensively evaluated the current situation macro- and mesoeconomically by gradually shifting from the comparison of countries to regional trends. I traced patterns of medical and demographic processes in the Finno-Ugric countries, such as Hungary, Finland and Estonia, and national autonomies across Russia. Conclusions and Relevance. I discovered that there is a certain relationship between a man and environment that translate into physical and physical health of people. They should be taken into consideration when outlining demographic development programs. The findings can be used to prepare regional medical and demographic documents, including the prevention of suicidal behavior and alcoholism and general medical services.

Flupropanate (sodium 2,2,3,3 tetrafluoropropanate), a slow-acting lipid bio- synthesis-inhibiting herbicide, was recently registered in New Zealand as Taskforce (745 g/L flupropanate as the sodium salt) for the selective and long-term control of Nassella trichotoma (nassella tussock) in pastures. In five dose-response experiments in permanent hill pastures in Canterbury, conducted between 2012 and 2016, we measured the efficacy of the herbicide against established plants of N. trichotoma and its residual activity against recruiting seedlings. Mortality, as an average across the five sites, was 93% 1.5 years after applying 1.49 kg flupropanate/ha (the label-recommended rate), and 100% at 2.98 kg/ha. This indicates that an application rate higher than the label rate will be necessary for complete control of a N. trichotoma infestation. The presence of 1,000 and 6,250 visible seedlings of N. trichotoma/ha in the autumn 3.2 and 2.1 years after applying 1.49 kg flupropanate/ha (at a Greta Valley and Scargill site respectively) indicates that the herbicide’s soil residues had decayed within 12 months to a concentration lower than necessary to kill the germinating seedlings of N. trichotoma.
