  A virtual environment was developed for PC and Android to be used with a desktop display and the Gear VR, respectively. The goal with it is to measure and enhance the spatial skills of people, because the latter can be achieved by solving simple geometric problems. Originally, this virtual environment consisted only of three such tests, namely the Mental Rotation Test, Mental Cutting Test and Purdue Spatial Visualization Test. Measurements were done in the past with these tests, but now the Heinrich Spatial Visualization Test is also included in the virtual environment. In this paper, its implementation and future measurement plan are presented.

  The purpose of this study is to propose the selection of installation sites based on publicly available data and sour cherry refrigeration container specifications, as well as to estimate the number of containers to be installed at possible sites. Today's escalating fuel supply and fuel price extremes make it particularly important to develop a sensible logistics sub-solution in the complex process of production, harvesting, storage, processing and sales. We undertook to develop a geospatial system that can be built and operated economically, its data sources can be updated occasionally or even at regular intervals, it is suitable for producing other outputs with additional descriptive or spatial data.

  The quality of urban is more and more affected by the accelerating urbanization. The efficiency of improving air quality can be increased by providing local information on each pollutant source. The aim of our activity is providing real-time high-spatial reasultion data about air quality of the Hungarian capital city, Budapest. In this paper, results of testing and calibration of different low-cost electrochemical sensors and localization of them are represented. The first selected sensor is suitable for detecting carbon dioxide (CO2), alcohols, benzene (C6H6), nitrogen oxides (NOx) and ammonia (NH3). The RingAir initiative also aims to involve the urban population in active environmental monitoring activities, therefore in the future we are planning to implement a more detailed and continuously updated monitoring system with the participation of a Budapest bicycle courier service and some of the city's population.
