Fizinis aktyvumas vienas iš sveikos gyvensenos ir geros savijautos komponentų, todėl fizinio aktyvumo skatinimas bei tinkama motyvacija turėtų būti neatsiejama moksleivių ugdymo dalimi ne tik mokykloje, tačiau ir namuose. Fizinis aktyvumas ypač naudingas moksleiviško amžiaus vaikams, kuomet dar vystosi organizmas, bei turi teigiamos įtakos vaikų mokymosi efektyvumui. Susiformavę fizinio akyvumo įgūdžiai jauname amžiuje, dažnai išlieka ir vyresniame amžiuje, todėl svarbu fizinio aktyvumo įgūdžius pradėti formuoti kuo anksčiau. Mokinių fiziniam aktyvumui turi įtakos įvairios priežastys – asmenys bendraujantys su vaikais, asmenininiai veiksniai, aplinkos sąlygos. Tyrimo objektas – mokinių fizinis aktyvumas ir jį motyvuojantys veiksniai Baigiamojo darbo tikslas – nustatyti mokinių fizinį aktyvumą motyvuojančius veiksnius. Darbo uždaviniai: 1. Nustatyti 9-10 klasių mokinių fizinį aktyvumą bei jį motyvuojančius veiksnius. 2. Nustatyti 11-12 klasių mokinių fizinį aktyvumą bei jį motyvuojančius veiksnius. 3. Palyginti mokinių fizinį aktyvumą motyvuojančius veiksnius skirtingose amžiaus grupėse. Tyrimo išvados: 1. Tyrimo rezultatai leidžia teigti, kad 9-10 klasių moksleiviai yra fiziškai aktyvūs, 70% mokinių sportuoja nuo 2-3 iki 7 ir daugiau valandų per savaitę ir 80% 9-10 klasių mokinių ne pamokų metu sportuoja, mankštinasi 2-3 ir daugiau kartų per savaitę. 72% laisvalaikį renkasi praleisti užsiimdami fiziškai aktyvia veikla. 60% 9-10 klasių mokinių labiausiai skatina...

After some time following the global depositions and pollution after the Chernobyl NPP accident, Lithuanian soils are most contaminated with 137Cs and 90Sr. In the work the 137Cs accumulation as well as vertical and horizontal migration in soil have been evaluated. The specific activity of the artificial origin 137Cs in tree segments has been determined, coefficients of its transfer from soil to various parts of the woody plant have been evaluated and compared with the transfer of the natural origin radionuclide 40K. The radionuclide accumulation both in soil and plants, wash–out from the environment and radioactive decay last for years, therefore it is expedient to choose proper methods and evaluate tendencies of the long–term contamination variation. Radionuclides having penetrated into the environment are accumulated in the vegetative ground cover and upper soil layer. Their accumulation in plants occurs directly from the atmosphere through their above–ground parts, while from leaves, branches and sprays as well as root surface radionuclides get into plant tissues and join the biological metabolism. These processes have not been evaluated sufficiently yet, though it is important from both biological and environmental point of view. After evaluating the radionuclide penetration into trees through their above–ground part and roots, radionuclide accumulation and distribution in a tree can be modeled and forecasted as well as a reverse task can be solved – their volume...

General Characteristic of the Disertation The problem The development of mankind is inevitably related to the ever increasing impact on nature. During recent decades due to scientific and technical advances, human possibilities of influencing the nature began to substantially exceed our ability to understand, evaluate and forecast consequences of this activity, quite often unexpected and unacceptable. With the nuclear technology development, along with other problems there occurred the problem of the environment contamination with radioactive substances. Their consequences are felt over many years, and radionuclides having penetrated into the environment take part in the exchange processes between various natural media, migrate over long distances, get into biological objects and accumulate in them. Previously, especially after the Chernobyl nuclear power plant (NPP) accident, and currently most attention both in the world and in Lithuania is paid to the investigations of specific activity of radioactive substances in the environment. However, there are a lot of problems of evaluating their biological danger, accumulation, migration and withdrawal in the environment from different environmental objects as well as of forecasting these processes. From the atmosphere radioactive substances are withdrawn with dust, they can be washed out with precipitation and decrease during radioactive decay. Radionuclides deposited to the ground surface are absorbed by soil and vegetation... [to full text]

Two long-term fertilization trials were established in 1966 on a Calc(ar)i-Epihypogleyic Luvisol at LUA Experimental station (Kaunas district). Experimental data of the period 2004 – 2005 presented in the paper shows the impact of long-term fertilization of mineral and organic fertilizers, its combinations on soil biological activity. Experimental data shows that the influence of various rates of fertilizers and their combinations on enzyme activity and respiration intensity was different. Hydrolases - urease and sacharase - activity more influenced by using mineral fertilizers, whereas oxidoreductases – dehydrogenases – activity more influenced by using mineral and organic fertilizers. Mineral fertilizers increased urease activity by on average 12 percent, whereas sacharase activity was not influenced, compared with unfertilized. The application of organic and mineral fertilizers increased activity of thus enzymes, accordingly 33 and 7 percent. In the second trial, treated with organic and mineral fertilizers, dehydrogenase activity was significantly influenced by application only rate of and 100 t ha-1 of manure per crop rotation. Under application of only mineral fertilization dehydrogenase activity in soil increased, compared with unfertilized. Average data of two years investigations under application of mineral – organic fertilizers and its combinations show that soil respiration intensity was significantly influenced by application only rate of N100P60K60.

It is assumed that such sampling allows to outline dominating opinions. The research revealed that not all students of Vilnius Pedagogical University are socially active. Main difficulties encountered by students are problems related to combination of work and studies (because most of the students work), as well as the lack of funds for various activities. A shared aim of youth organisations is to foster creative, free individuals by creating conditions for self-growth and its encouragement. A socially active student shapes values of humanity and is preparing to become a future teacher and a citizen of our democratic society. The research showed that students are more concerned about their health, subsistence, work, tough financial situation; it shows lack of interest in the world, in public issues and in problems of the higher education establishment. The youth, especially students, plays an important role in the current... [to full text]
