MACROECONOMIC CONSEQUENCES OF THE DEMOGRAPHIC AND EDUCATIONAL CHANGES IN POLAND AFTER 1990

Soon after the start of transition to a market economy in the early 1990s, Poland has experienced both a dramatic decline in the fertility rate and an increase in the share of students among young high-school graduates. These two processes significantly changed the age structure of population and average income characteristics of households. Using a general equilibrium model with heterogeneous households and uninsured income shocks, I try to assess the impact of these changes on the Polish economy as a whole and inequalities within it. I find that, in the long term, the positive effects of the educational change on output per capita will more than offset the negative impact of lower fertility. I also show that the educational change increases income and consumption inequalities, while the fertility change decreases inequality in assets.

The requirements in medical rehabilitation of adult population of different age groups in hospital conditions

The study was carried out to determine requirements of adult population of Russia in medical rehabilitation in hospital conditions depending on age groups. To determine requirements of country population in medical rehabilitation in hospital conditions the age-specific indicators derived from data massive from three territories were standardized on population and morbidity in Russia in 2010. The number of hospitalized patients being in need of medical rehabilitation in hospital conditions was determined as indicator characterizing requirements of population in medical rehabilitation in hospital conditions. The age-specific requirements of adult population in medical rehabilitation in hospital conditions was determined and analyzed on the basis of number of cases of annual hospitalization for medical rehabilitation in hospital conditions according main classes and particular diseases. The largest number ofpatients being in need of medical rehabilitation in hospital conditions goes to elder age groups 60-69 years (874.7 cases per 10 000 of population) and 70 years and older (1346.3 cases per 10 000 of population). The least number of this kind of patients goes to age group of 18-29 years (106.2 cases per 10 000 of population). The proposed calculated number of cases of hospitalization of adult population for medical rehabilitation in hospital conditions can be implemented by executive authorities of subjects of the Russian Federation in health care sector of any territory for determining requirements ofparticular region in medical rehabilitation with consideration for age structure of population.

Age structural impact of adolescent and youth on fertility transition in Nepal

Nepal is in unique period of demographic situation. The age structure of population is gradually shifting upwards producing a historical large proportion of young population. Given the early age at marriage and childbearing, this population may continue to dominate fertility transition process. Interaction between improvement in the characteristics of this population and recently started declining fertility is expected to push fertility transition at a faster rate until mid of this century before entering to the lowest level marginal decline or stagnation. The young 1population itself are in social, economic, cultural and demographic transition which is sandwiched with generation gap. Demographic analysis should factor their needs and interests to project the future fertility discourse.

Dmitriy Mendeleev’s Forecasts of the Population of Russia. and the Realities of its Present Development

In his last work “The Sacred Thoughts” an outstanding Russian scientist and encyclopedist Dmitri Ivanovich Mendeleev has explored demographic processes, acting as an economist and sociologist. The author of this article examines methodical approaches and tools, repeats and continues calculations of Mendeleev using modern data and information technologies. Comparing Mendeleev’s forecasts of the size and age structure of population of Russia with the modern statistical data, the author discusses the reasons for the “failure” of forecasts. The arsenal of modern demographic tools can be supplemented with Mendeleev’s idea on using the formula (law) of the vertical parabola in studying the age structure (the dependence between the size of the group and age).

Primates (Symphalangus syndactylus syndactylus, Macaca nemestrina, Macaca fascicularis) Population in the Ape Park Tourist Area Forest for Special Purpose of Aek Nauli

Forest for special purpose of Aek Nauli is an highland rainforest as habitat for primates and tourism area in Marsose, Sibaganding Village, Simalungun, Lake Toba Geopark in North Sumatra. As an endangered and protected species, siamang (Sympalangus syndactylus syndactylus) in the same habitat as pig-tailed macaque (Macaca nemestrina) and long-tailed macaque (Macaca fascicularis). Nowadays, the siamang population is declining due to the conversion of forest to non-forests, forest fragmentation and illegal trade. Long-tailed macaque and pig-tailed macaque are agricultural pests that are economically harmful to communities around the forest. The primate population data is needed as input for the sustainable management strategy by stakeholders to further preserve forest areas and primate populations. This study was carried out for 3 months from May to July 2018. To determine the number of primate populations performed by the concentrated area method. Estimates of primate populations are: A. Siamangs; 1 group with 3 individuals, population size 0.06. Age structure of population 1 juvenile 1, 2 adults. B. Pig-tailed macaque; 3 groups with 65 individuals, population size 1.1. The age structure is 17 tillers, 17 adolescents and 31 adults. C. Long-tailed macaque; 3 groups with 23 individuals, population size 0.5. Age structure of 5 tillers, 7 adolescents and 11 adults.

THE AGE GENDER AND CLINICAL ANAMNESTIC CHARACTERISTICS OF ATYPICAL CLINICAL FORMS OF ACUTE MYOCARDIUM INFARCTION

Purpose of study. To investigate age gender and clinical anamnestic characteristics of patients with atypical clinical forms of acute myocardium infarction.Materials and methods. The study was based on data of the WHO programs “The register of acute myocardium infarction”. The analysis comprised 836 cases of acute myocardium infarction. The atypical clinical forms of acute myocardium infarction were detected in 184 patients (18.7%). In the structure of atypical clinical forms of acute myocardium infarction the following alternatives were appropriated: asthmatic (32,6%), collaptoid (31,5%), abdominal (13.6%), arrhythmic (7.6%), peripheral (5.4%)б painless (4.9%) and cerebral (4.3%).Results of study. The most of the males (62.5%) found themselves in the group of patients with abdominal form of acute myocardium infarction and most of the females in the group with cerebral form of acute myocardium infarction. In all analyzed groups the individuals older than 60 years prevailed. In the group of patients with cerebral form were most of the individuals underwent earlier acute myocardium infarction (50.0%). The diabetes mellitus most frequently was registered in individuals with painless acute myocardium infarction (55.5%). In all cases, course of acute myocardium infarction was complicated. Under atypical clinical forms of acute myocardium infarction higher lethality was registered and in groups with arrhythmic and cerebral forms it reached 100%.The conclusion. The whole group of patients with atypical clinical forms of acute myocardium infarction was presented by over-age contingent, severe in clinical, anamnestic and prognostic layouts. The unsatisfactory diagnostic of atypical clinical forms of acute myocardium infarction resulted in higher lethality of the given group of patients. With regard to that a general tendency of alteration of age structure of population of Russia is a steady increasing of percentage of individuals of older age groups t5he rate of occurrence of atypical clinical forms of acute myocardium infarction will regularly increase.

Analysis Of Invasive Flora In Cemetery Territories Of The City Of Daugavpils

Alien species are reaching different areas, including also cemeteries. Inventory of invasive flora of cemeteries of the city of Daugavpils actually is the first such type of work to such level of detail on the Latvian scale. Field studies were conducted in 10 cemeteries of the city of Daugavpils. The obtained results are indicative of a comparatively high proportion of invasive plant species in the cemeteries. 49 invasive alien species were found. In the cemetery areas these are spreading mainly from greeneries, but there are also such taxa, which have accidentally reached the cemeteries. The most frequent plant in the Daugavpils cemeteries is Spiraea chamaedryfolia. Taking into account the trends of migration, sex-age structure of population, climate change, availability of exotic and new ornamental plants, it is most likely that the number of invasive species will grow in the future.

Specificity of population trends in Vojvodina - the 2011 census

According to the 2011 Census, Vojvodina has the population of 1,931,809 which is by 100,183 less than in 2002. Vojvodina has fewer inhabitants today than in 1971. This decrease in number of inhabitants, according to the latest census, occurred in all municipalities except in the City of Novi Sad, where the population annually increased by 4,703. The main objective of this paper was to analyze the movement of population between two censuses, focusing on the specifics of population movements in certain areas of Vojvodina. First of all, the area of the North Banat should be pointed out because there the population has been steadily declining since 1961. On the other hand, the South Backa area records a steady increase in population in the period from the World War Two to the present, mainly due to the mechanical movement or immigration to the center of this area - the City of Novi Sad. In addition to the population decline, the population of Vojvodina is characterized by higher average age. The last census showed that the population of all municipalities was, on average, older than 40, except in the municipality of Zabalj (39.7) and the City of Novi Sad (40.0). Analysis of the data has shown that the trend of the population decline in Vojvodina, caused by very high mortality rates and low birth rates, continues and that the age structure of population is becoming less favorable.
