Opis:
Rising food prices mean that solutions are sought that will reduce the costs of agricultural production. One area of research is precision agriculture. This solution requires a computerized plant growth monitoring system. The paper presents a computer system for monitoring plant growth, developed for the needs of precision agriculture for small agricultural areas. The work contains a description of the monitoring system divided into the key elements of the process. An exemplary method of preparing orthophotomaps of the area was presented. The method of making maps that can be implemented on a personal computer has been described. The paper describes the most frequently used Geologic Indicators and Vegetation Index. A test of determining the coefficients was carried out on exemplary acreage with an area of 5.28 ha. Typical positioning systems for agricultural machines are discussed. The DGPS (Differential Global Positioning System) navigation method was used in the tests, which confirmed that it can be used in precision agriculture for small agricultural areas while maintaining sufficient positioning accuracy. The presented system was tested during one cycle of vegetation of winter barley sown with the no-plowing method. On this basis, an analysis of savings resulting from the reduction of the amount of fertilizers and plant care products used was carried out. The proposed system does not require complicated computer systems. It was designed in such a way that it can be implemented on standard PC equipment cooperating with a short-range drone equipped with a standard RGB (Red Green Blue) camera.

Opis:
The article's primary goal is to demonstrate the problems inherited in 'operationism - antioperationism' polemics. The opinions on operationism are divided. The term 'operationistic views' is a conceptual cluster, in which the components' meanings are imprecise. The term 'operational definition' shares the same quality. In general science methodology many distinguished social science methodologists continue developing and modifying operationism. Both the supporters and critics of operationism have succeeded in formulating a significant number of prominent methodological issues; operationism studies inspire thinking on the methods of concepts, indicators and techniques selection in science as well as on the reasoning for the choices made. I suggest to call the extension of operativeness postulate the operativity postulate. It reads: concepts are to be defined through descriptions of observable states of matter. Definition's operativity postulate shall be applied to definitions of indicated properties (in cases of definitional indicator) as well as to definitions of indicators (in case of correlation indicator).

Opis:
The research aimed to make an inventory of the vascular flora of 11 parks and gardens of the Pomeranian Cistercian Trail, with particular emphasis on taxa attached to old deciduous forests. A total of 62 species were registered, recognised as indicators of old deciduous forests in Poland. The presence of species of this group was confirmed in all of the analysed objects, but their number varied from 7 to 50. The group of ancient woodland species includes forest species for which the light indicator values are lower than or equal to 4 (plants of shadowy places, with a relative light intensity). The group of indicator species also includes forest geophytes and forest myrmecochores, autochores and barochores, as well as woodland species that can tolerate stress, under the classification of ecological strategy types S, S/CSR, S/SC and S/SR.

Opis:
The paper presents a method of obtaining short-term positioning accuracy based on micro electro-mechanical system (MEMS) sensors and analysis of the results. A high-accuracy and fast-positioning algorithm must be included due to the high risk of accidents in cities in the future, especially when autonomous objects are taken into account. High-level positioning systems should consider a number of sub-systems such as global positioning system (GPS), CCTV – video analysis, a system based on analysis of signal strength of access points (AP), etc. Short-term positioning means that there are other locating systems with a sufficiently high degree of accuracy based on, e.g. a video camera, but the located object can disappear when it is hidden by other objects, e.g. people, things, shelves etc. In such a case, MEMS sensors can be employed as a positioning system. The paper examines typical movement profiles of a radio-controlled (RC) model and fundamental filtering methods in respect of position accuracy. The authors evaluate the complexity and delay of the filter and the accuracy of the positioning in respect of the current speed and phase of movement (positive acceleration, constant) of the object. It is necessary to know whether and how the length of the filter changes the position accuracy. It has been shown that the use of fundamental filters, which provide solutions in a short time, enables to locate objects with a small error in a limited time.

Opis:
In the article problems related to human labor and factors affecting the increasing use of industrial robots are discussed. Since human factors affect the production processes stability, robots are preferred to apply. The application of robots is characterized by higher performance and reliability comparing to human labor. The problem is how to determine the real difference in work efficiency between human operator and robot. The aim of the study is to develop a method that allows clearly definition of productivity growth associated with the replacement of human labor by industrial robots. Another aim of the paper is how to model robotized and manual operated workstation in a computer simulation software. Analysis of the productivity and reliability of the hydraulic press workstation operated by the human operator or an industrial robot, are presented. Simulation models have been developed taking into account the availability and reliability of the machine, operator and robot. We apply OEE (Overall Equipment Effectiveness) indicator to present how availability and reliability parameters influence over performance of the workstation, in the longer time. Simplified financial analysis is presented considering different labor costs in EU countries.

Opis:
An important question stated in the presented paper is: Could rotifers be the indicators of climate change in the Antarctic environments? Rotifers are one of the most important components of the invertebrate fauna of the Antarctic freshwater and terrestrial ecosystems. However, investigations of their distribution, diversity and an ecological role in the environment have been widely neglected, mainly due to the methodological and taxonomical difficulties. During the investigations 176 species of rotifers were found, including the endemic and cosmopolitan species. Their existence is directly proportional to microvariations of humidity factor. Scientists still have poor knowledge about the occurrence of rotifer species in recently studied habitats e.g. cryoconite holes, nunataks or soil. Probably rotifers could be the indicators of climate change in the Antarctic freshwater and terrestrial ecosystems but more investigations and monitoring studies are needed.

Opis:
The article proposes the use of a synthetic indicator in spatial research. In the construction of synthetic indicator, it assumes that the indicator should not only specify the synthetic value based of on empirical data, but also show its structure. The structure of the indicator should answer the question to what extent individual empirical measures influence to the value of a synthetic indicator. Using the rules of statistical grouping, four groups of voivodships with different economic potential were distinguished. Research shows that on the synthetic indicator of voivodships (in particular groups) were affected to a varying extent by the values of empirical variables: number of employees, value of fixed assets, value of gross domestic product, number of economic operators.

Opis:
The economy of Slovakia experienced a turning point in the 1st half of 2008 and entered a phase of decline. The negative impacts of the global economic crisis became evident in the 2nd half of 2008 and led into a recession in the 1st quarter of 2009. The composite leading indicator was originally intended for forecasting of business cycle turning points between the decline and growth phases. The aim of this paper is to transform the qualitative information from composite leading indicator into quantitative forecast and verify whether the beginning of recession in Slovakia could have been identified in advance. The ARIMAX and error correction models are used for the composite reference series and GDP forecasts respectively. The final result shows that the composite leading indicator is useful not only for identifying turning points, but also for the prediction of recession phase.

The value of the integrated indicator of the united territorial communities land use is determined. An assessment of the integral indicator was carried out and directions for the development of methodological recommendations to improve the efficiency of land use of the united territorial communities were identified. A feature of the use of GIS for analysis and visualization of integrated indicators of land use of the united territorial communities is the development of a geoinformation analysis scheme. The developed scheme of geoinformation systems using for modelling, evaluation, and analysis of integrated indicators of the united territorial communities land use gives the opportunity to form information and analytical support of monitoring based on geospatial information and to create the basis for increasing the united territorial communities land use. The sequence obtained in the article ensures the monitoring of changes in the spatial characteristics of the lands of the united territorial communities in the region. The results of determining the integral indicators of land use of the united territorial communities obtained in the article make it possible to carry out geoinformation analysis and build a GIS map of the land use. The developed GIS map allows the formation of information and analytical monitoring support based on the values of integrated indicators of land use. Also, the data of the presented map allow to predict the directions of land use of the united territorial communities, to compare them by territorial features and features depending on changes of system spatial, urban, investment and ecological factors.

Opis:
The civilisation progress has caused noise to become one of essential pathogenic and life comfort decreasing factors. There are several legal regulations aimed at controlling the noise influence on humans. Assessment of the twenty-four-hour influence of noises in various environments constitutes an essential problem. The answer can be supplied by 24-hour monitoring of the sound pressure. This paper is an attempt to learn the real loading of humans by noises. A personal noise indicator was used in measurements. The human 24-hour activity was divided into cycles allowing to model noise hazards. The collected data, even though they did not signal exceeding of individual standards, in the 24-hour period indicated the essential noise influence. These results indicate the need of investigations to recognise the 24-hour noise load of a human, with taking into account various forms of their activity and the need of rest.

In order to ensure the territorial development of land use in the region, there is a need to change the trajectory of spatial and urban planning factors. The ways for implementation of the proposed system measures are defined in the article. For investment and environmental indicators, the integrated indicator of territorial development of land use in the region, depending on their change, is predicted. The article presents the results of forecasting the integrated indicator of land use territorial development in the region based on the growth of systemic investment factors and the results of forecasting the integrated indicator of land use territorial development based on the growth of systemic environmental factors. Practical scientific-based recommendations for ensuring the territorial development of land use in the region by applying the results of its integrated assessment and modeling are proposed. Developed recommendations made it possible to form directions and build the basis for ensuring the territorial development of land use in the region. The development of methodological recommendations for ensuring the territorial development of land use in the region is based on the results of the study of the influence of systematic spatial, urban, investment, and environmental factors on the integrated indicator of land use territorial development.

Opis:
The problem of estimation of the long-term environmental noise hazard indicators and their uncer- tainty is presented in the present paper. The type A standard uncertainty is defined by the standard deviation of the mean. The rules given in the ISO/IEC Guide 98 are used in the calculations. It is usually determined by means of the classic variance estimators, under the following assumptions: the normality of measurements results, adequate sample size, lack of correlation between elements of the sample and observation equivalence. However, such assumptions in relation to the acoustic measurements are rather questionable. This is the reason why the authors indicated the necessity of implementation of non-classical statistical solutions. An estimation idea of seeking density function of long-term noise indicators distri- bution by the kernel density estimation, bootstrap method and Bayesian inference have been formulated. These methods do not generate limitations for form and properties of analyzed statistics. The theoretical basis of the proposed methods is presented in this paper as well as an example of calculation process of expected value and variance of long-term noise indicators LDEN and LN. The illustration of indicated solutions and their usefulness analysis were constant due to monitoring results of traffic noise recorded in Cracow, Poland.

Opis:
The transformation processes that occur in the technical, informational, and economic spheres of the regions require the development of new conceptual approaches to the development of a full-fledged land use system based on an analysis of the problems of using underground real estate. Determination of the features of land use of underground real estate is based on a quantitative basis, which is built on a systematic, integrated approach. Indicators that determine the condition and use of underground real estate are of particular importance for the development of the approach. A method of estimating a generalized indicator of the use of underground real estate in the system of land use of regions based on an integrated approach, which includes the method of expert assessments by applying qualitative indicators characterizing the status and level of use of underground real estate, considering urban, spatial, investment and innovation legal and safety features is developed. The assessment results of the integrated indicator of underground real estate land use, as well as the results of the assessment by region, showed a low level of use of underground real estate in the land use system of the regions. It is determined that most of the lands in the regions have low levels of underground real estate use. Besides, there is a need to increase the use of underground real estate by developing appropriate methodological recommendations.
