<p> This study is a search for an analytical framework within which the structural factors constraining the Nigerian development process can be highlighted.</p> <p>We examine the input-output method and its relationship to planning a less developed country. The input-output table available for Nigeria is analysed using conventional techniques. Certain indices are derived in an attempt to throw some light on the evaluation of the development process. 'Ihe importance of designing an input-output table within the context of the particular problem to be solved is emphasized. </p> <p> A comparative analysis is made of the Nigerian table and an input-output table for Zambia, to highlight the relationship between the design and the use of an input-output table in the planning process. Furthermore, the elements involved in designing a table that would come to grips with the question of structural transformation, are discerned. In particular, the need to relate the classification of economic activities in an input-output matrix to the planning problem emerges.</p> <p> The data provided in the Nigerian table are used to illustrate the sort of basis on which an input-output table could be built if there is to be a link between a formal description of the economy and the simulation of change.</p> <p> The study illustrates the extent to which the development process depends on the planners' recognition of the relationship between the problem of transformation and the nature of structural constraints in the economy. In this way, it is possible to isolate systemic malfunctions in the economy and identify in connection with these, the areas of weakness in the planning process.</p> <p> It is also seen that if the input-output model is to be useful in planning structural transfoTmation, it must be able to accommodate radical changes in the structure of production and a normatively determined pattern of demand. The scope of the conventional model must be broadened to allow the planner to emphasize target groups of people in relating the structure of production to the pattern of demand.</p> / Thesis / Doctor of Philosophy (PhD)

Šiame darbe analizuojamos pasaulinio semantinio tinklo technologijos dalykinės srities žinioms užrašyti ir valdyti. Darbo metu buvo papildyta dalykinės srities ontologija bei sukurta nauja sistėminė vartotojo sąsajos formavimo ontologija, kuri palaiko daugiakalbystę. Realizuotos ir aprobuotos užklausos ir automatizavimo procesai dirbantys su minėtomis ontologijomis. Darbo vykdymo metu sukauptos žinios buvo surinktos, susistemintos ir pateikiamos kaip darbo metodika. Remiantis šia metodika sukurta eksperimentinė sistema, skirta padėti identifikuoti su BIOS klaidomis susijusias problemas ir/arba operacinių sistemų (OS) sutrikimo priežastis ir jas spręsti. Apie sukurtą sistemą buvo perskaitytas pranešimas konferencijoje „Mokslas ir studijos 2010: teorija ir praktika“, kuri įvyko Šiaurės Lietuvos kolegijoje. Metodiką galima pritaikyti bet kokiai dalykinei sričiai, tiek realizuojant e-mokymo(si) sistemose probleminio mokymosi principus, tiek paramos paslaugų teikimo prekės ar produkto vartotojui sferoje. / This work examines the global semantic web technologies in the subject area knowledge and record management. Work was completed in the subject area and Ontology, a new user interface making systemic ontology, which supports multilingualism. Realized and dealer inquiries, and automate processes in working with these ontologies. Work during the accumulated knowledge has been collected, systematised and presented as a working methodology. Based on the methodology developed an experimental system designed to help identify errors in the BIOS-related problems and / or operating systems (OS) and cause disruption to solve them. This system of notification was read in the conference of "Education and training 2010: Theory and Practice", which took place in Northern Lithuania College. The approach can be applied to any subject area, and implement e-learning (learning) problem of learning the principles of systems and support services or goods to the consumer product area.
