New technologies gives an ability transfer business processes to more automated layer in such a way ensuring efficiency and labour productivity. This process is complex and imperative to improve and growth. Usability of software depends on software quality as on growth of information technologies culture. Human ability to analyze and process informational flows is quite limited and time consuming. For this reason software and hardware are essential ensuring accurateness, well-timed and automated processing of information. Processed, accurate and well-timed information is useful for any organization. There is no software which can carry out all business activities, but people having potency to use software as a tool and analyze given information ant results are also required. Only in that case an increase of efficiency and labour productivity is possible while using software.

Mobile E-voting application system - software and hardware solution for e-voting elections. We have reviewed and analyzed present electronic voting systems, that were realized on public elections. There are many e-voting systems, but no one of them reach today’s needs, because all of them has just one, two or three voting ways, but no one has almost all and most needed of them. Another problem is security. We have created two levels security solution, to secure votes in the e-voting terminals, until they will be send to then central voting system. All mobile e-voting application system has three levels, then first is central voting station, the second is district voting station and the last is terminal. The data from the central station to the district station goes through the VPN (Virtual Private Network) and from the district station to the terminal goes through the WLAN modem. We have formed technical, information, user interface requirements and models for the mobile E-voting application system. There are described possible solutions for computer network, database and user interface. Experimental example shows a few Mobile E-voting application system functions.

Tyrimo objektas – informacinių technologijų įtaka darbuotojų santykiams individo lygmenyje. Darbe įvertinami teoriniai darbuotojų santykių aspektai. Darbuotojų santykiai apibūdinami kaip procesas, kuriame darbuotojai bendrauja su vadovais, darbo grupėmis bei darbo aplinka, siekiant asmeninių bei organizacijos tikslų. Taip pat analizuojami darbuotojų santykiai vadybos istorijos eigoje. Be to, analizuojami ir socialiniai motyvai kurių dėka darbuotojai gali patenkinti savo poreikius: poreikius bendrauti, poreikius save išreikšti bei poreikius augti ir tobulėti savo organizacijoje. Remiantis tuo išskiriamos darbuotojų santykių struktūrinės dalys (motyvacija, kompetencija, bendravimas, pasitenkinimas darbu). Taip pat darbe analizuojami ir įvertinami teoriniai informacinių technologijų aspektai. Šiuolaikinės informacinės technologijos suteikia ne tik diddžiulias bendravimo galimybes ar informacijos srautus, bet turi įtakos darbuotojų santykiams. Jų dėka darbuotojai patiria stresines situacijas, tampa socialiai izoliuotais, mažiau dėmesio skiria tiesioginiam „akis į akį“ bendravimui. Remiantis teorine analize sukurtas tyrimo modelis, kuris įvertina informacinių technologijų įtaką darbuotojų santykiams Lietuvos organizacijose. Atlikto tyrimo rezultatai rodo, kad šiuolaikinės technologijos turi tiek tiegiamos, tiek neigiamos įtakos darbuotojų santykiams. Jų dėka darbuotojai jaučia pasitenkinimą darbu, didėja jų motyvacija ir kompetencija. Tačiau informacinės technologijos nesukuria...
