Recently, the interest of Unmanned Aerial Vehicle application in photogrammetric environment for roads observation and monitoring has increased in many countries, in Lithuania as well. The experimental object for demonstration of capability and efficiency of aerial vehicle-based remote sensing technology for road data collection was a western bypass of Vilnius. The platform of the model UX5 Trimble with mounted camera Sony NEX-5R was applied for gaining images. The implemented means are mobile and not expensive. Photogrammetric technique with software package Business Center Photogrammetry Module was applied for the modelling of images. The correctness of digital surface model generally depends on camera resolution, flight height and accuracy of ground control points. The coordinates of control points were determined using Global Positioning System Trimble R4. Paper demonstrates results of a new technology application possibilities for linear object (road) mapping and accuracy evaluation of spatial models. The road points positioning accuracy investigation was carried out in consideration with geodetic control measurements. The average root mean square error for the points coordinates is 2.94 cm, and standard deviations – 2.78 cm. Analyzing coincidence or mismatches of Vilnius western bypass project data with photogrammetric product, not significant discrepancies of road section features were determined. The cost consideration of Unmanned Aerial Vehicle in conjunction with photogrammetry employment at experimental object is presented. © 2015 Vilnius Gediminas Technical University (VGTU) Press Technika.

In the construction industry of the Baltic States, the aftermath of the economic crisis poses new questions as to what occasioned the crisis. The paper analyses a causal relationship between foreign direct investment in construction (CFDI) and the contribution of the construction industry to gross domestic product (GDP) using data obtained in the Baltic States (Lithuania, Latvia and Estonia) for the period from 2000 to 2011. The conducted research includes the initial econometric analysis of variables, which involves the verification of seasonality and stationarity with the help of time series plots, a unit root test and Granger causality test. The study has found that, in the case of Lithuania and Estonia, CFDI is not the Granger cause of the construction industry's contribution to GDP growth; conversely, value added by the construction sector is not the Granger cause of FDI into the sector, and there is one-way causality from value added by the construction sector to CFDI, and the construction industry's contribution to GDP does not influence CFDI in Latvia.

The rectification of high resolution digital aerial images or satellite imagery employed for large scale city mapping is modern technology that needs well distributed and accurately defined control points. Digital satellite imagery, obtained using widely known software Google Earth, can be applied for accurate city map construction. The method of five control points is suggested for imagery rectification introducing the algorithm offered by Prof. Ruan Wei (Tong Ji University, Shanghai). Image rectification software created on the basis of the above suggested algorithm can correct image deformation with required accuracy, is reliable and keeps advantages in flexibility. Experimental research on testing the applied technology has been executed using GeoEye imagery with Google Earth builder over the city of Vilnius. Orthophoto maps at the scales of 1:1000 and 1:500 are generated referring to the methodology of five control points. Reference data and rectification results are checked comparing with those received from processing digital aerial images using a digital photogrammetry approach. The image rectification process applying the investigated method takes a short period of time (about 4-5 minutes) and uses only five control points. The accuracy of the created models satisfies requirements for large scale mapping. © 2011 Vilnius Gediminas Technical University (VGTU) Press Technika.

Ecological farming is relevant to protected areas. The aim of the study is to perform an analysis of farms applying organic farming measures as well as the analysis of the change of their areas in Aukštadvaris and Krekenava regional parks (RP). The object of the investigation-the farms of Aukštadvaris and Krekenava regional parks. The study is carried out to determine how many farms, forming the regional parks' territory, are managed according to the principles of organic farming. The change of the above- mentioned farming area for 2009-2011 is analyzed as well. Paluknys and Naujamiestis subdistricts, not incorporated into the territory of regional parks, were chosen for the comparison analysis. The analysis of the 2009-2011 period showed that the declared areas in Krekenava RP have decreased, and the area of farms applying organic measures has increased by 81.69 hectares (nearly 2.5 times). The number of organic farms increased by 1.5 times in Aukštadvaris RP over the period of 2009-2011, and the area has increased by 187.36 ha. The percentage calculations revealed that in 2011 the area of farms applying organic farming measures in Aukštadvaris RP made up 18.89 per cent of the total area declared, the number of farms-6.61 per cent. The area of farms applying organic farming measures in Krekenava RP was only 1.71 per cent, measures were applied only by 1.89 per cent of all the declared.

This study presents the results of electromagnetic feld parameters measurements in an open area under different air temperature and humidity conditions. An attempt to consider the electromagnetic wave as a holistic harmonic oscillation, which takes into account all frequency components of the field at the measurement point, was also presented in this study. During the measurements, the closest electromagnetic radiation sources were taken into account. Therefore, measurements of field parameters were produced in specific frequency bands. For the simplification of large data, the spectrum decimation technique was applied. As a result, measurements and data processing were revealed to characterize the electric field strength and the magnetic flux density when air temperature increases. The field parameters dependences on air relative humidity have a decreasing tender. © 2015 European Union.

Abstract Background: Understanding the reasons and consequences of leadership styles in ethical dilemmas is fundamental to exploring nurse managers abilities to influence outcomes for patients and nursing personnel.To explain the associations between different leadership styles, reasons for their application and its consequences when nurse managers make decisions in ethical dilemmas.The data were collected between 15 October 2011 and 30 April 2012 by statistically validated questionnaire. The respondents (N = 278) were nurse managers. The data were analysed using SPSS 20.0, calculating Spearmans correlations, the Stepwise Regression and ANOVA.The reasons for applying different leadership styles in ethical dilemmas include personal characteristics, years in work position, institutional factors, and the professional authority of nurse managers. The applied leadership styles in ethical dilemmas are associated with the consequences regarding the satisfaction of patients, relatives and nurse managers needs.Nurse managers exhibited leadership styles oriented to maintenance, focussing more on the doing the job than on managing the decision-making in ethical dilemmas.
