Nuotolinio mokymo technologijos įgauna pagreitį visame pasaulyje. Technologijos trūkumai ir silpnosios vietos tampa matomesnės, nei bet kada anksčiau. Siekiant patobulinti mokymo procesą ir sumažinti kurso nebaigiančių studentų dalį, vis svarbesnėmis tampa studentų aktyvumo skatinimo ir mokymosi paramos sistemos. Šio darbo tikslai – apžvelgti esamus studentų aktyvumo analizės ir valdymo metodus naudojamus nuotoliniame mokyme. Taip pat, pagerinti esamus arba pasiūlyti gaires naujų kūrimui. Literatūros analizė parodė duomenų gavybos metodų potencialą mokymo valdymo sistemose. Pasiūlytas studentų aktyvumo skatinimo modelis pagrįstas šiais metodais. Naujasis modelis paremtas automatiškai besireguliuojančia sistema, kuri analizuotų besimokančiųjų mokymosi įpročius. Analizės duomenys būtų naudojami sukurti ir siųsti personalizuotus priminimus ir pranešimus apie mokymosi sistemos įvykius. Ta pati sistema galėtų informuoti kurso vedėją apie neįprastus studentų veiklos pokyčius, padidėjusią nesėkmingo kurso baigimo tikimybę. Atliktas tyrimas patvirtinantis modelio kūrimui pasirinktas prielaidas ir jo reikalingumą. / Distance education technology is gaining momentum all around the world. Weaknesses and limitations in the technology are exposed more than ever. Activities, such as, stimulation of students’ activity and development of support systems are becoming important in attempts to lower student dropout rates and improve quality of education. This thesis has goals to review existing methodology of analyzing and encouraging student activity in higher education courses based on online technology. As well as to enhance current methods and set guidelines for development of the new ones. Literature analysis has highlighted the astonishing potential of data mining methods in Learning Management Systems. Based on these methods a new model of students’ activity stimulation has been suggested. The new model is based on automatic self tuning system which would analyze the behavior patterns of course users. The results of this analysis would be used to compose and send notifications of course events which are relevant for and desired by the individual user while respecting their learning patterns. Same system could inform instructor of any abnormalities in student learning behavior, unfavorable odds to successfully complete the course or even drop out. A study has been made, which confirmed the initial assumptions and potential usefulness of the proposed model.

The study is devoted to problems of exposure caused by radionuclides in construction materials. Results received by gamma measurements and calculations (dose modeling) are used. Construction materials produced and/or used in Lithuania were investigated. The results of measurements (concentrations of natural radionuclides and activity indexes) are given for different types of construction materials. On the basis of these results and peculiarities of use of construction materials they have been classified according to their radiological significance. It helps to determine possible amounts of construction materials to be investigated and priorities of investigations. Relationship between activity indexes of different construction materials and dose rates in premises constructed of these construction materials has been determined. It might be used for increase of precision of personal dosimetric measurements performed in premises constructed of different materials. Possible relationship between absorbed dose rate indoors and concentration of indoor radon is discussed. Results of measurements of concentrations of natural radionuclides in archeological samples of construction materials are also presented and discussed. Dose modeling has been performed with the help of ALARA planning tool Visiplan 3D. Distributions of absorbed dose rate in standard living premises have been determined, relationship between dose rate and different parameters of constructions, such as thickness... [to full text]

“Influence of physical activity on III–IV form students` self-image in personal wholeness context” Key words Physical activity, forms of physical activity, subjective evaluation of appearance, subjective evaluation of health. Topicality of the theme Nowadays development of students` physical activity as well as development of students` self- knowledge tendencies are under major consideration. Development process is orientated towards students, their expansion of physical abilities, their needs and interests, where parents, teachers, social life changes and means of such reflection have visible influence. The urgency of work is related to a problem which has not been analysed enough, it is the influence of physical activity to the self-image (subjective evaluation of self-appearance and health, selection of forms of physical activity) of III–IV form students formers. Cultural significance for students` development and health was analysed by A. Zaborskis (1993), A. Zaborskis and other authors (1996), I. J. Zuozienė (1998). Positive aspect of sport for development child`s personality was explained by J. Kralikauskas (1993), A. V. Matulionis (2002). Problem How physical activity affects III–IV form students` self-image in personal wholeness context? The aim of research To establish students` (III–IV forms) physical activity influence for appearance and health subjective evaluation and forms of physical activity preferences.

Tyrime dalyvavo 18 - 69 metų amžiaus 92 tiriamieji, 63 moterys ir 29 vyrai. Darbe naudoti tiesioginis (akselerometrija) ir netiesioginis (IPAQ-LT trumposios versijos klausimynas) metodai, siekiant įvertinti tiriamųjų bendrą savaitės fizinį aktyvumą ir palyginti gautus duomenis tarpusavyje. Kiekvienas tyrimo dalyvis IPAQ-LT trumposios versijos anketą pildė baigęs fizinio aktyvumo (FA) vertinimą akselerometru (buvo prisimenamas FA praėjusios savaitės – pirmas anketų pildymo atvejis) ir kitą - po savaitės baigus FA vertinimą akselerometru (buvo prašoma ,,prisiminti“ FA vykusį už praėjusią savaitę - antras anketų pildymo atvejis). Pagal IPAQ-LT trumposios versijos pirmo ir antro anketos pildymo atvejų gautus bendrus savaitės fizinio aktyvumo duomenis, tarp pirmo ir antro anketos pildymo atvejų egzistuoja vidutinis koreliacinis ryšys (rho=0,531, p=0,01). Vertinant akselerometro pagalba gautus duomenis ir lyginant juos su anketų duomenimis (bendro savaitės fizinio aktyvumo pirmo ir antro anketos pildymo atvejų) tarp akselerometro nustatyto FA ir IPAQ-LT pirmo anketų pildymo atvejo egzistuoja silpnas koreliacinis ryšys (r=0,270, p=0,009), o tarp antro IPAQ-LT anketų pildymo atvejo – labai silpnas ryšys (r=0,057, p=0,591). Tyrimo metu gauti rezultatai leidžia teigti, kad dauguma tyrime dalyvavusių savanorių savo fizinį aktyvumą buvo linkę pervertinti. Tyrimo objektas - IPAQ-LT trumposios versijos klausimynas ir jo patikimumo bei pagrįstumo nustatymas. Darbo tikslas – nustatyti...
