The cadastre and the land book form a unitary and mandatory system that ensures technical, economic and legal records of all the properties on the territory of the country. This paper includes the presentation of the operations necessary to prepare the cadastral documentation for detachment in two lots, using UAV photogrammetric technology. The studied area is located in the suburbs of Valea Ierii locality, with an area of 212353 sqm. The main part of the project was based on the use of the UAV photogrammetric method to survey the area. At the same time, two GNSS receivers were used to complete the photogrammetric measurements. Control and verification points were premarked on the ground, the coordinates of which were determined by the real-time kinematic GNSS method. This operation was followed by performing the photogrammetric flight using an UAS platform. The flight lasted about 17 minutes, covered an area of 29 ha and 288 frames were captured. The front overlap between  photos was set to 75% and the side overlap to 65%. New technologies for taking frames and processing them have been adopted, through methods that involve a low cost and a shorter time to perform specific operations.

Patients with cancer are a high-priority population for COVID-19 vaccination, as per guideline recommendations. The present cross-sectional study was performed to assess the perception of patients with cancer from Romania regarding COVID-19 vaccines. The study included 932 patients with solid and hematologic malignancies. This was a multicenter study including 12 oncology centers located in Western and Northwestern Romania. Between December 2021 and January 2022, patients with cancer completed an individual paper questionnaire regarding acceptance of the SARS-CoV-2 vaccination, type of vaccine, side effects and source of information. During the first year of the vaccination campaign in Romania, 58.05% (541/932) of the investigated patients received COVID-19 vaccines. The vaccination rate was highest in the 61-70 year age group (61.22%). The most frequently used vaccine was Pfizer-BioNTech (72%). There was a statistically significant association between the rate of vaccination and the area of residence and level of education (P<0.001), with rural residence and a lower level of education being predictive factors for COVID-19 vaccination hesitancy. Patients living in rural areas used non-medical sources (e.g. mass media, social platforms) as their main source of information (53.40%, 204/382), whereas patients living in urban areas (64.90%, 357/550) used predominantly medical sources (e.g. recommendations from oncologists and general practitioners). The main source of information among non-vaccinated patients was mass media (e.g. television, radio); 72.38% vs. 29.67% among vaccinated patients. For the latter, the primary source of information was the recommendations made by oncologists (59.70%) and general practitioners (56.76%). The most commonly reported side effect was injection site pain (20-33% for the first dose and 5-27% for the second dose). In conclusion, the present study confirmed that patients with cancer may be reluctant to receive a COVID-19 vaccine, mainly due to the fear of its potential side effects. Although there is scientific evidence to support the efficacy and safety of vaccines, the primary source of information for patients may affect vaccine uptake, thus affecting the efforts to stop the pandemic. Furthermore, the

Population management is difficult and complex due to its dynamic and complexity. When we talk about demography, we talk about human population in a defined geographic area, meaning, demography is a spatial science. Geographic Information System (GIS) is a modern tool used in many fields, to manage attribute data and spatial data, including population management. The aim of this study is to present the size of population for each county and urban/rural area on two different years: 2012 and 2020, and the estimation of population growth until the year of 2050. Used for processing spatial data, ArcGIS package from ESRI, allows spatial and geostatistical analysis, mathematical calculations and the visualizations of data. Modern cartography is using GIS technologies to create maps in an easier and flexible way. GIS can use the existing analog maps after digitizing them. Using GIS, specialists can create maps at any scale, centered on any location and showing any selected information. ArcGIS tools permit to visualize, query and overlay the data bases related to the maps. Using ArcGIS applications, we determined the counties which present an increasing of population, and those presenting a decreasing of population, as well as the evolution of population in urban and rural area. In order to determine which counties are affected more by the population decline, we calculated the growth rate using the three major demographic variables: Birth, Death and Migration. In conclusion, we can say that the population in Romania has decreased in the past 8 years and is going to decrease even more in the next 30 years. This happened due to the low birth rate and high emigration rate.

The minor riverbed of the Someș River is identified in the built-up area and the outside of the built-up area of Fărcașa ATU and the Ardusat ATU outside the built-up area, from the Ardusat DJ 193 road bridge, between hm 2725-2855 and between hm 2815-2867, according to GD (Government Decision) 1705/2006. For the first registration work of the Someș minor riverbed, the measurements, their processing and the afferent documentation were made in accordance with the Order of the general director of the National Agency for Cadastre and Real Estate Advertising no. 700/2014, updated in 2020. The purpose of the project refers to the topo-cadastral methods performed for the elaboration of the documentation of first registration in the Land Book of the minor riverbed belonging to the Someș river located within the radius of ATU Ardusat and ATU Fărcașa from Maramureș county. For the acquisition of the necessary data, both field works and office operations for data processing were taken into account, the studied area being 222.7 hectares. Measurements were performed using GNSS technology using the real-time kinematic RTK method. The UAV aerial photogrammetric method was used to obtain a high degree of detail. The drone used was equipped with an RTK module that receives real-time corrections, thus maintaining a high accuracy.

Urban green spaces (UGS) contribute to the development of the ecosystem, especially in crowded urban areas such as cooling effect, air and noise pollution mitigation, recreation, aesthetic pleasure, quality of life and public health, as well as economic benefits, such as raising the price of the real state in the vicinity of UGS. The aim of the paper is to realize a study on green spaces and an urban distribution of the size of a systematic planning of functional and aesthetic qualities. This study examines the distribution and amount of green space, as well as the size and rates per capita are assessed. Even the distribution of distance and the accessibility of green areas throughout the city are closely linked to ensuring recreational needs. Spatial statistics using GIS have made possible the development of correct, coherent explanatory UGS variables such as distance, size, density, connectivity, sight and accessibility. The parks and all green spaces composed of polygons were digitized from the ArcGIS Attribute Table for the evaluation of per capita rates and the execution of a plan to combat the deficit of green spaces. In order to make an assessment of the green spaces, a comparative study of the area of interest from 2010 and 2020 was considered. According to the spatial analyses from ArcGis, during the 10 years, an intense real estate market was developed, affecting the distribution of green spaces per capita.
