Modern youth will live in the world of quick changes when industrial society will change into information society. That’s why the reform of Lithuanian Education faces changes according to present information requirements. The shortage of appropriate program equipment is a serious obstacle to successful integration of computer science into educational process. Teaching chemistry we can do much accommodating various innovations, creating new teaching facilities, using experiments and modeling programs. Feed-back is very important as well. The knowledge must be tested. Combining ordinary testing with modeling we can achieve good results and educational process would become more attractive, motivation would increase. In this work needs and opportunities of applying computer science in chemistry lessons will be analyzed. Computer appliance in teaching how to solve chemistry problems at school has been created. It consists of three parts: teaching material (triangle „The solving of chemistry problems“), Visual Basic models and TestTool tests. The device will be useful for students who want to learn solving chemistry problems or want to revise the course. The web-page „Solving Chemistry Problems“ is of high quality and meets the needs of learners. Visual Basic models satisfy the teachers requirements and show the best learning way. The tests correspond to the curriculum, are reliable and useful.

Organizacijų veiklos aplinka yra greitai kintanti, taigi organizacijoms reikia visada numatyti veiklos pokyčius bei būti pasiruošus valdymo metodų keitimui. Žmogui suspėti numatyti visus galimus veiklos pokyčius yra pakankamai sunku, nes tai užima daug laiko. Jo veikla tampa nelabai efektyvi, tuo tarpu kompiuteris atlieka šį procesą greičiau, tačiau jo padaryti sprendimai gali būti neefektyvūs. Šią problemą galima būtų spręsti sukuriant organizacijos žinių valdymo informacinę sistemą, kuri sujungtų žmogaus turimas žinias ir kompiuterio spartų darbą. Jos pagalba organizacijos valdymo pokyčiai vyktų paprasčiau ir būtų efektyvesni. Kad sukurti organizacijos žinių valdymo sistemą pirmiausia turi būti išanalizuoti artimą metodologiją turintys modeliai, įvertinti jų privalumai ir trūkumai. Taigi, šiame darbe pirmiausia juos ir išanalizuosiu. Atliksiu KAOS, DoDAF, CommonKADS, MEMO, VGM bei EVC metodologijų lyginamąją analizę bei patikrinsiu jų tinkamumą veiklos valdymui modeliuoti. Remiantis tinkamomis metodologijomis, šalinant jų trūkumus, panaudojant privalumus bei pridedant naujus elementus bus sukurtas veiklos valdymo modelis. Darbo objektas: Organizacijos žinių valdymas. Darbo tikslas: Sukurti organizacijos žinių valdymo sistemą paremtą vertės grandinės modeliu. Šiam darbo tikslui pasiekti buvo iškelti tokie darbo uždaviniai: 1. Išanalizuoti vertės grandinės modelio ir jo modifikacijų taikymą veiklos modeliavime. 2. Išnagrinėti analogiškų metodologijų principus. 3. Patikrinti...

One of main task in information system development is to project good graphical user interface. It is used many different methods, tools and princess for automatic user interface generation. ODRES (output driven requirements engineering) method witch is developed in the department of information system has an ability to generate graphical user interface from its user developed specifications. These specifications are stored in specification storage – database and they are strictly defined. The tool used to generate graphical user interface from selected ODRES storage reads those specifications and transforms them into graphical elements. An engineer can change those elements. At the end of generation user interface prototype is saved in the same specifications storage.

The domain of this research are CASE tools, designated for requirements engineering, which are able to generate computerized information system prototypes. The main goal of this project is to design software, which would enable to generate an IS prototype from requirements specification, created re specification method, suggested by the Information Systems department. The software is a part of a CASE tool, designed by the IS department. The CASE tool is designated for creating requirements specification and the software will provide additional functionality to it. The opportunities of computerized IS prototyping using Oracle Designer, Visual FoxPro and MS Access were analyzed. In case of Oracle Designer, in order to create a computerized IS prototype we have to go through the whole design stage. In case of DBMS Visual FoxPro and MS Access we must have a database designed. And the software for generating computerized IS prototype enables you to generate a system prototype at an early design stage and without having the system project.

This solution allows creating prototype for all customers, and adding special customer’s defined functions very simply. The project goal was to improve Tapestry functionality and ability for web applications, and create a web portal framework with content management, document management and users rights management subsystems in it. The design, problems, results and project realization are fully described in this document.

The target of this project was to generate a prototype, which would model the elements of the user interface based on the information flow specification. The system is programmed using MS Visual Basic for Applications, its’ graphical environment is MS Visio 2000 and the elements of GUI for modeling are taken from MS Visio 2000 stencil WUI (wui.vss). The created module allows for easy modeling of graphical user interface elements for the data source, which is selected from the database. The processing stages of the data sources are illustrated using MS Visio 2000 documents’ windows, – one window for each stage. In the database, the elements of GUI are associated with the data source processing stages they are related to, i.e. the ones that they are present in. It means, that when working with the system, after selecting the desired data source and its processing stages one wants to model, the system generates the forms with associated GUI elements. This work was being done in the order of the scientific group of Information systems design, which analyses the design of the Information systems in the wide context of requirements engineering, process and data structures specification. This designed and realized model is going to be a part of a CASE tool meant for designing computerized information systems. Once the CASE tool is finished, it is planned to use it for educational purposes in Kaunas University of Technology in the department of Information systems. It is going to... [to full text]

Automatization system prototype of Finance Macler Company.

Visose pasaulio kalbose yra terminai spalvoms reikšti, tačiau priklausomai nuo ekstralingvistinių veiksnių, skirtingos tautos turi nevienodą jų skaičių. Išanalizavę dešimtis kalbų lingvistai B. Berlinas ir P. Kėjus nustatė, jog ankstyvame kalbų raidos etape tebuvo du žodžiai spalvoms apibrėžti: vienas - tamsioms, kitas – šviesioms. Šviesai atstovauja balta spalva, tamsai – juoda. Į prototipines baltumo ir juodumo konceptų reikšmes (baltas, -a – sniego spalvos, visai šviesus, juodas, -a – visiškai tamsus, kaip anglis) remiasi nemažai metaforinių reikšmių. Šio magistro darbo tikslas – išskirti skirtingas ir bendras baltumo ir juodumo metaforines reikšmes, būdingas lietuvių ir anglų kalboms. Tyrimo medžiagą sudaro lietuvių kalbos tekstyno grožinės literatūros blokas ir anglų kalbos tekstyno medžiaga. Išanalizavus tekstyno medžiagą nustatyta, jog prototipinės juodo reikšmės: tamsus, neperregimas, tankus, gilus; nešvarus, suteptas; rasė, gymis; rūšies pavadinimas; kava, arbata; metaforinės reikšmės: nešvarus, nedoras; prastas apie maistą (tik lietuvių kalboje); blogis: a) viduje išgyvenamas (emocijos); b) bauginantys, tragiški, nelaimingi įvykiai, su jais sietinos vietos; sunkus, kasdienis; neteisėta veikla, tokios veiklos rezultatai; simbolinės reikšmės: artėjančios nelaimės simbolis; nelaimės pranašai (blogio simboliai); gedulo simbolis. Tekstyno medžiagos analizė parodė, jog prototipinės balto reikšmės: šviesa; perregimas, bespalvis; švara; tuštuma; rasė, gymis; rūšies...

Kay analysed dozens of languages and determined that there were only two colour terms (dark and bright) in the first stage of language evolution. Bright is represented by white and dark is represented by black. Many metaphoric meanings are based on prototypical meanings of concepts of whiteness (white – of colour of snow, very bright) and blackness (black – very dark, like coal). The goal of this master thesis is to determine common and different metaphorical meanings of whiteness and blackness characteristic for Lithuanian and English languages. The research material is collected from corpuses of Lithuanian and English languages. The data of the analysis of both concepts showed, blackness and whiteness in most cases are used to identify a feature of colour, i.e. prototypical colour meaning. But it also revealed a number of cases when the colour term does not denote a colour feature, but it is used metaphorically, with objects lacking the colour feature. The analysis has also revealed the importance of the symbolic meaning in the research of the colour concepts. The concept of Blackness in both languages is perceived similarly. Prototypical meanings are the following: dark, lacking light, impenetrable, soiled; used to characterize dark skin pigmentation; certain object in black colour (blackcurrant, black bread and etc.); (coffee or tea) without...

Reikalavimų inžinerija yra bene svarbiausias etapas informacinės sistemos kūrime. Tik tikslus reikalavimų specifikavimo proceso valdymas leis sėkmingai projektuoti, realizuoti ir įdiegti informacines sistemas kompiuterizuojamose srityse. Dažnai neefektyvus reikalavimų rinkimo procesas tampa projekto nesėkmės ar programinės įrangos defekto pagrindu. Be to, aptiktų netikslumų pašalinimo kaina kyla eksponentiškai, kai jie atrandami vėlyvosiose projekto stadijose. Todėl įmonės ar asmenys, siekiantys pagerinti projekto kokybę ir produktyvumą, turėtų ypatingai atkreipti dėmesį į reikalavimų valdymo procesą. Pastebėta, jog reikalavimų specifikavimo procesas vis labiau kompiuterizuojamas, o reikalavimų valdymo įrankių bei šablonų naudojimas gerina reikalavimų specifikacijos ir būsimo produkto kokybę. Šis magistrinis darbas yra skirtas reikalavimų specifikavimo šablonų pagrindu eksperimentiniam tyrimui ir jo vertinimui. / The usage of computers takes more important place in our modern life. It was noticed that more and more enterprises use requirement management tools and specification templates to increase quality of requirement specification and projects. Very often ineffective requirements-gathering processes are the source of project failures and software defects. In addition, the cost of fixing defects rises exponentially as their discovery occurs later in the development process. However, a solid requirements process is fundamental to an effective overall process, and companies seeking increased quality and productivity should start with the requirements process. The intention of this work is to make the experimental research of requirements specification using templates and evaluate it.
