A tanulmány a kinetikus iskolarajz (Kinetic School Drawings, KSD) értelmezését mutatja be a rendszerszemléletű konfigurációelemzés (SSCA) módszerével. A bevezetőben kifejezéspszichológiai szemléleti keretet vázol fel, amelyben a rajzot a kifejező viselkedés részének tekinti, elhelyezi a tesztet a rajzvizsgálatok rendszerében és röviden kitér a teszt előzményeire. A tesztfelvétel módszere után részletesen ismerteti a kinetikus iskolarajzok rendszerszemléletű konfigurációelemzési módszerét. Célja, hogy olyan értelmezési módszert adjon a gyakorló pszichológusok kezébe, amely szótárszerű jelentésadás nélkül vezet el a kinetikus iskolarajz megértéséhez és olyan összefüggések hálózatát eredményezi, amelyek mindig egyedi módon szólnak a gyermekről. A tanulmány befejező része a kinetikus iskolarajzokkal végzett, hazai kutatási eredményekről ad összefoglalót.

Bayes Procedure

Bayesian estimation is presented for the stationary rate of disappointments, D∞, for two models (with different specifications) of intermittently used systems. The random variables in the system are considered to be independently exponentially distributed. Jeffreys’ prior is assumed for the unknown parameters in the system. Inference about D∞ is being restrained in both models by the complex and non-linear definition of D∞. Monte Carlo simulation is used to derive the posterior distribution of D∞ and subsequently the highest posterior density (HPD) intervals. A numerical example where Bayes estimates and the HPD intervals are determined illustrates these results. This illustration is extended to determine the frequentistical properties of this Bayes procedure, by calculating covering proportions for each of these HPD intervals, assuming fixed values for the parameters.

Purpose. The purpose of the work is to analyze the theoretical and regulatory provisions relating to the definition of forms of preventive action to combat illegal migration and used in the protection of the state border. Methodology. The method covers the application of general theoretical and special methods of scientific knowledge aimed at processing the conclusions of the study. The dialectical method, system analysis, classification and grouping methods, as well as the sociological method are used in the work. Results. The use of the most appropriate and lawful preventive measures is associated with the definition of a scientifically sound system of crime prevention, detailed structural characteristics of which in the activities of the State Border Guard Service of Ukraine to combat illegal migration are covered by two main blocks: procedural and operational. The procedural block concentrates such forms as operative-search activity, proceedings in cases of administrative offenses, proceedings on the application of forced return, forced expulsion and readmission of foreigners or stateless persons. The operational-service block covers the following forms: border service, border control, operational-search and information-analytical activity, engineering-technical control, complex preventive measures (operations). Scientific novelty. According to the results of the research, the system of forms of crime prevention in the activity of the State Border Guard Service of Ukraine on counteraction to illegal migration is substantiated, which envisages procedural and operational-service blocks. Forms of the procedural block of prevention of illegal migration are characterized by the impact on the offense, which has a preventive value, as well as the focus on the restoration of the disturbed state. Operational and official forms of prevention of illegal migration are designed to prevent offenses, as well as their detection to ensure an appropriate procedural response. Practical significance. The results of the research can be used in research work for further study of general and special issues of improving the fight against illegal migration, in the field of lawmaking - to improve the current administrative and migration legislation of Ukraine, in the educational process during the organization of educational activities and teaching administrative law. cycle, in law enforcement - to increase the efficiency of bodies and units of state border protection.

The architectural and ecological model of civil engineering of socially oriented spaces of coastal landscape aimed at providing comfortable vital environment, development of the greatest possible variety of city activities, solution of environmental and social problems of the city, and development of the embankment as a self-valuable fragment of well-arranged natural landscape is substantiated. The research objective is the development of methodical bases for the process of architectural revitalization of postindustrial coastal landscape. The researchers utilize the methods of system analysis, reviewing of design practice, analysis of available scientific databases as well as referential and normative resources. The methods of modeling and experimental projecting were also used in the study. Architectural proposals on integration of the revitalized postindustrial coastal areas into socially oriented area of the Volgograd embankment are presented. The analysis of the experience in building and recovery of postindustrial landscapes of river basins is preformed to substantiate the proposed architectural and ecological principles of revitalization, "tree of properties" with the definition of environment quality indicator, the sequence of stages in planning of socially oriented area of the city embankment, and experimental project on integration of the studied coastal area into the vital space of the city of Volgograd.

Purpose This study aims to test the role of the state of occupation, represented in Israel, as one of the most significant challenges, which faces the Jordanian water security. Where Israel expands in its policy and ideology everyday its hydro-hegemony over the Jordanian waters. Hence, its acts result in negative consequences on the Jordanian water and food security, which in turn affects the Jordanian national security as a whole. Design/methodology/approach This study relied on the following two approached to tackle its problem: first: descriptive approach: the descriptive approach depends on defining the apparent features and describing their nature and the type of the relationship between its variables. It aims to achieving a better and deeper understanding on the situation of its future policies and measures. And research uses the system analysis approach to handle the subject matter. Given the influence of water on the development, Jordan, as an organic or a political and social state, takes into account the reasons and causes of development. Jordan turns into an active political state, with water as an influencing factor on it. This premise represents the core of the system analysis approach. Findings The research concluded that the Israeli theft of the Jordanian waters is the main factor in the Jordanian water crisis. If Jordan had received its usurped water rights by Israel, it could have been able to solve its water issue represented in the increasing deficit in its water balance. Therefore, the Israeli hydro-hegemony on the Jordanian water resources caused the imbalance in its water security and, in turn, caused the development process to falter in general. Originality/value The value of the research lies in the fact that it addresses the most important reasons behind the water crisis in Jordan, represented in the Israeli control over the Jordanian water resources and the research shows that the amount of water stolen by Israel is enough to solve the water crisis in Jordan.

System analysis is used to state links between input and output parameters of any technical system taking into consideration flows of material, energy, and information. This approach makes it possible to find effective ways for improvement of technical system parameters. The paper presents results of system analysis application for multioperational technological process steel sheet of hot rolling. Structural scheme of metal sheet hot rolling process is presented based on principles of system analysis. Hot rolling technological operations such as workpiece heating, hot rolling, cooling, and coiling are presented as subsystems. Due to the obtained schemes metal sheet parameters are stated which have to be controlled during each technological operation of hot rolling technological process. The obtained results can be used as the basics for mathematical modeling of steel sheet hot rolling operation in order to get the final product with the required set of properties.
