SANTRAUKA Temos aktualumas. Lyderystė ir organizacinis pasitikėjimas – svarbūs organizaciniai reiškiniai, kurių nebuvimas ar trūkumas tam tikra dalimi sąlygoja neefektyvią organizacijos veiklą, tuo pačių veikiama ir šalies ekonomika. Akademinių darbų apie lyderystės sąsajas su organizaciniu pasitikėjimu nėra gausu. Praktiškai nėra įvertintas galimas šių reiškinių panaudojimas organizacijos veiklos optimizavimui. Lietuvoje informacinių technologijų įmonių paklausa didėja kaip ir visame pasaulyje – pereinama prie automatizuotų verslo valdymo sistemų, kurios optimizuoja įmonių veiklą, taupo kaštus, gerina organizavimo galimybės. Kadangi lyderystė ir atitinkamai organizacinis pasitikėjimas daro įtaką organizacijų produktyvumui bei finansiniams rezultatams, įvertinti IT įmonių situaciją organizacijų viduje ir bendrai Lietuvoje yra aktualus klausimas, kuris nėra išsamiai ištirtas. Darbo objektas – Lyderystės ir organizacinio pasitikėjimo santykis organizacijoje. The goals of the work: 1. Ištirti lyderystės koncepciją ir jos tipus; 2. Išanalizuoti organizacinio pasitikėjimo sampratą; 3. Atskleisti teorinę lyderystės ir organizacinio pasitikėjimo sąveiką; 4. Išanalizuoti lyderystės ir organizacinio pasitikėjimo matavimo priemones; 5. Remiantis teorijomis ir empirinių tyrimų analize, sudaryti lyderystės ir organizacinio pasitikėjimo sąveikos įvertinimo modelį; 6. Apibūdinti ryšį tarp lyderystės ir organizacinio pasitikėjimo ir remiantis modeliu, empiriškai ištirti lyderystės savybes...

Daugiakarčio tikslumo aritmetikos biblioteka LiDIA kriptografijos kurse / LiDIA is a Libary For Computational Number Theory in Cryptography CourseŽitkevičienė, Edita 08 June 2006 (has links)
LiDIA is a library for computational number theory. Since we find that object oriented programming is appropriate for implementing mathematical algorithms and since C++ belongs to the most accepted programming languages in scientific computing, we decided to use C++ as the implementation language for LiDIA. To guarantee easy portability of LiDIA we decided to have a very small machine dependent kernel in LiDIA. That kernel currently contains the multiprecision integer arithmetic and a memory manager. All LiDIA objects are implemented in C++ and compiled with many different compilers on various architectures. Information about LiDIA can be found in website http://mokymai.dist.su.lt/. RSA scheme, algorithms of factorization, tests of prime numbers, some elements of modular arithmetic are analysed there. Although not in the public domain, LiDIA can be used freely for non commercial purposes.

SUMMARY During the political and economic changes of Lithuanian system the institutions of public social welfare services, which were administered by Government Administration, gained more freedom in their discretion. However, some things have not changed, such as an old attitude towards employees, worn out management position. It is very difficult for the society to transform, since it has used to old, soviet methods of working. Various researches, which were conducted by different authors, show that employees themselves determine a successful realisation of tasks and goals; therefore only using adequate Human Resources Management is possible to create such system, where both management’s (administration) and employees’ needs are met and ascertains accomplishment of the risen tasks and aims of the organisation. Currently, Social Welfare Services of Lithuania are at the point of the development and a rapid growth. There are essential performs ongoing at the Institutions of Social Welfare Service – reductions in quantity of the residents, the present living conditions are being improved, the structure of the staff is being reconstructed as well. In reality, there are often detected an ineffective solutions of Human Resources Management problems in practice of Institutions of Social Welfare Services as well as incompetence, inability to achieve the risen tasks, goals and expectations of their clients. This shows, that the problems of the public organisations of Social... [to full text]
Tiesioginio matomumo zonų nustatymo programos sudarymas ir tyrimas / Development and analysis of direct visibility zone detection programBučelis, Mindaugas 10 January 2005 (has links)
Summary Spatial visibility detection Geographic Information System (GIS) developers come across number of various tasks ant the computers using the specialized software might ease the solution. One them is detection of direct spatial visibility. The essence of this task is to check if one spatial point can be seen from a given position. Research point’s altitude, coordinates and the information about the objects in surrounding are given. Spatial visibility may not exist if there are objects intersecting the ray from the viewpoint to researched point. Intersecting objects may be buildings, roughness of surface as well as trees and other higher object in area. Detection of direct spatial visibility is essential for transmission of high and medium frequency radio waves or optical signals. To fulfill this task the program will be developed with which assistance the zones of direct spatial visibility can be obtained. The possibility to work with several viewpoints also should be provided. The program would help to find out the heights, positions and quantity of the transmitter aerials to optimize the visible area. Initial data is the altitudes of buildings and surface in researched area. The data is given in text files created by Arc/Info system.

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.
