The workspace design is usually treated as a part of the user interface design without paying a lot of attention to a workspace design. Such approach works rather well when small IS, which consists of tens of functions and only few actors, is being designed. However, in such case finding optimal and fast solutions can become problematic when IS workspace is being designed for large scale IS. The purpose of this work is to present a model of computerised workspace functionality specification, using information flows specification. The creation of workspace structure is based on function hierarchy model. After making analysis of computerized workspace design and functions modeling, the function hierarchy modeling technique and process of building computerized workspace should be presented, implemented and verified. Also the CASE tool for function modeling and structure of workspace design is described.

Darbo tikslas. Įvertinti profilaktinių ergonomikos principų taikymo darbo vietoje mokymo poreikį ir galimybes „X“ įmonėje. Uždaviniai. Įvertinti darbuotojų informatyvumą apie ergonomines darbo padėtis, darbo ir poilsio režimą, specialius akių ir fizinius pratimus ir jų atlikimą per pertraukas „X“ įmonėje. Nustatyti profilaktinių ergonomikos principų taikymo darbo vietoje mokymo darbuotojams poreikį ir galimybes „X“ įmonėje. Tyrimo metodika. Tyrimas buvo atliktas 2012 m. gruodžio – 2013 m. sausio mėn. „X“ įmonėje, kurioje darbuotojai dirba kompiuteriu visą darbo dieną. Anoniminės anketos būdu buvo apklausti 123 darbuotojai. Duomenų analizei buvo apskaičiuotas Chi kvadrato kriterijus, taip pat, z kriterijus. Reikšmingumo lygmuo, kai p<0,05. Rezultatai. 12,2 proc. darbuotojų, kurie sieja savo sveikatos nusiskundimus su ergonomine darbo padėtimi, ir 38,8 proc. respondentų, kurie nesieja, sėdi tiesiai naudojantis kompiuteriu (p<0,05). Apie 5 – 10 min. pertraukas yra neinformuota 96,3 proc. nedalyvavusių panašiuose ergonomikos mokymuose, 94,6 proc. respondentų, kurie sieja sveikatos nusiskundimus su ergonomine darbo padėtimi bei 100 proc., kurių darbo stažas 10 – 20 m. Informuoti apie fizinius ir specialius akių pratimus buvo 1,9 proc. darbuotojų, kurie nedalyvavo panašiuose ergonomikos mokymuose, 5,4 proc. siejantys sveikatos nusiskundimus su ergonomine darbo padėtimi, labiausiai informuoti buvo dirbantys iki 10 m. tokio pobūdžio darbą (4,8 proc.). 73,1 proc. nedalyvavusių...

To evaluate employees‘ knowledge about an ergonomic work posture, work and rest regimens, the special physical and eye exercises and their performance during breaks at the „X“ company. To determinate training need and possibilities in application of the preventive ergonomic principles at the workplace of the „X“ company. Methods. The research was carried out during December 2012 - January 2013 period in the „X“ company, where employees work with computers all working day. An anonymous questionnaire was filled out by 123 employees. The Chi-square and z criteria were calculated for data analysis, and the level of significance was when p<0.05. Results. The rate of the employees, sitting straight in front of a computer, was 12.2% of those, who relate their health complaints with the ergonomic work posture, and 38.8% of the respondents, who do not relate (p<0.05). 96.3% of the employees, who have not participated in similar ergonomic trainings before, 94.6% of the respondents, who relate their health complaints with the ergonomic work posture, and 100%, whose length of employment is from 10 to 20 years, do not know about 5 – 10 min. breaks. About the special physical and eye exercises were informed 1.9% of the employees, who have not participated in similar ergonomic trainings before, 5.4% of the respondents, who... [to full text]

Darbe išanalizuota IS kūrimo principai ir problemos, pieno perdirbimo įmonės veikla. Pasirinktos užsakymų priėmimo sistemos projektavimo ir projekto realizavimo priemonės. Atliktas užsakymų priėmimo IS projektavimas. Sukurta duomenų bazė, kurios pagalba suprojektuota užsakymų priėmimo kompiuterizuota darbo vieta pieno perdirbimo įmonėje. / Company’s business computerization stands for creating and installing an information system which would satisfy all company’s needs. Such system’s creation and installation involves analysis of company’s demands, specification of them, physical and logical design, realization, testing and also subsequent maintenance and development.The main aim of this work is to design such information system which would be suitable for dairying plant. The system’s “Order Processing” interaction with other information systems that are used in the company would allow optimizing production coverage, cost and most important the quality of services.The deep analysis has been done in the dairying plant. Operating database systems have been reviewed.Testing of this system was performed by using virtual data.

There are widely used computers in agricultural mobile technique, which show important parameters of work process and its quality in. It is important a good illumination of workplace for quick and correct information identification from the VDT’s. There are forming different levels of illumination in agricultural technique cabins when they are working at the field. Those levels are fluctuating and operator’s eye should adapt to them compulsory. Operator’s vision feels fatigue because of those processes and work becomes not so effective. There are assessed in the work, that luminance increase on the VDT screen, as do illumination level in the cabins of agricultural mobile technique and as a result of this process, contrast reduces and visibility become worse. In experiment, there was researched, that tasks were performed quicker, when illumination was 300 -500 lx, and slower, when - 900-1200 lx. There are assessed the response time dependence on illumination level model , which helps to calculate the duration of operator’s watching, which influences the results of work quality and safety.
