Purpose: The aim is to evaluate the operation of the Model Teacher Training School drawing on the example of the “Model Teacher Training School in Niemcz and Osielsko” project completed against the project evaluation findings in terms of the directions of continuing the operation of the teacher training school and its effective impact on supported schools. Design/methodology/approach: The article presents a case study of a Model Teacher Training School in Poland as a modern teacher competence support system. There are identified some selected aspects of the operation of the teacher training school established as part of the project cofounded by the EU. Project evaluation research process is discussed and selected evaluation research findings are presented for the sample of 55 teachers, including headmasters and deputy headmasters of seven supported schools. The research process has involved diagnostic methods and tools: CAWI (Computer Assisted Web Interview), which uses the Microsoft Forms tool. Selected CATI qualitative research findings have been presented for a sample of 8 respondents, including the representatives of the Beneficiary and the Partner, headmasters and deputy headmasters of the Training School, the representatives of the higher education provider and the supporting institution. Findings: The school serving a function of the Training School performs actions focused on a teacher competence development in Supported Schools in selected forms and work methods. The idea of the modern approach to teacher competence enhancement is a cooperation of the Training School with experts of educational institutions: the higher education provider, supporting institutions and the education superintendent authority. It is also valuable every year to include new Supported Schools into the supporting process and improving the forms and methods of working with teachers. It is possible to the evaluation of the actions performed the findings of which facilitate a further determination of directions of continuing the operation of the Model Training School for the years to come. Research limitations/implications: Compliant with the Training School Model, the operation of teacher training schools should be subject to annual evaluation process, which will enhance the quality of the actions by increasing the correctness, effectiveness, usefulness, efficiency and lifespan. Some limitation to undertaking the research process is a problem with financing the evaluation research which must be financed outside the project. Practical implications: The evaluation research findings, including the expectations of supported schools’ teaching and management staff, have facilitated a further determination of support forms which should be offered by the teacher training school throughout the project, which is for the upcoming 5 years. The forms of support which should be continued throughout the project life offer a possibility of using ready-made teaching aids, a participation in discussion forums, sharing blogs and methodology workshops. The teachers have slightly lower expectations in terms of continuing their participation in conferences and seminars, working on-line on the doskonaleniewsieci.pl platform, taking part in demo classes, consultations and stationary cooperation networks. Social implications: The teacher training school operation will affect the social domain as the teacher training school, by offering an adequate support to the teachers and including new schools into cooperation, will enhance a development of the key student competences, especially foreign languages learning, mathematics, natural sciences, ICT and teachers sharing their knowledge and skills. Originality/value: The teacher training school model presented as well as the evaluation research findings provide a recommendation for practical professional development of primary school teachers in Poland.

Idea rozstrzygnięcia każdego projektu pochodzi ze źródła pozbawionego precyzyjnej definicji. Nie istnieje definicja źródła, jednak istnieje nierozerwalny splot wielu współzależnych warstw niezbędnych do kreacji, a wśród najważniejszych są: warstwy wiedzy i precyzyjnego myślenia, determinujące funkcje narzędzi myślenia, nadających kształt idei oraz warstwy wymykające się definicji, determinowane wyczuciem i wrażliwością twórcy, cechujące obszary sztuki. Jeśli świadomie kreowana forma, łącząca różnorodne materie, scala ciągi funkcji dla działań, konstruuje dla trwałości tworząc jednocześnie niepowtarzalne walory dla percepcji - wpisuje się w przestrzeń ARCHITEKTURY. Jeśli materia formowana przez człowieka wywołuje emocje i wrażenia, jeśli tworzy oferując iluzje, przenika i wzbogaca wyobraźnię pozostawiając w niej trwały ślad - wpisuje się w przestrzeń SZTUKI.

EN

The idea of resolving any project comes from a source without a precise definition. There is no definition of the source, but there is an inseparable weave of many interdependent layers necessary for creation, and among the most important are: layers of knowledge and precise thinking, determining the functions of the tools that give shape to the idea, and layers that escape definition, determined by the intuition and sensitivity of the creator, characterizing the areas of art. If a consciously created form combining a variety of matters, merges sequences of functions for activities, constructs for permanence while creating unique qualities for perception - it fits into the space of ARCHITECTURE. If the matter formed by man evokes emotions and impressions, if it creates by offering illusions, penetrates and enriches the imagination, leaving a permanent trace in it - it is inscribed in the space of ART.

Risk, as an effect of uncertainty, is associated with every human activity. Like any other industry, construction companies are eager to reduce the uncertainty of reluctant events. A well-planned risk communication system could contribute to the success of a construction project. A proper announcement protocol could be a mitigating lever for identified or unidentified risks during planning and monitoring processes. This research aims to present a risk communication management system (RCMS) for construction companies involved in large projects. The proposed model includes a step-by-step communication procedure considering the authority level within the organisational hierarchical structure. The model aims to remove the ambiguity of risk communications during the construction process under uncertain conditions. It leaves no or little room for the emergence of unplanned risks. The proposed communication structure has been implemented in GRC cladding construction projects, and the risk communication time and response have been significantly improved.

W artykule przybliżono innowacyjne narzędzie mające na celu przeciwdziałanie i zmniejszenie zagrożeń związanych z ruchem drogowym, w tym z obsługą miejsca zdarzenia przez funkcjonariuszy Policji. Narzędziem tym jest symulator wspomagający szkolenie policjantów w realizacji czynności na miejscu zdarzenia drogowego, który powstał w ramach realizacji projektu Wyższej Szkoły Policji w Szczytnie, finansowanego ze środków Narodowego Centrum Badań i Rozwoju w konkursie nr 9/2018 na wykonanie projektów w zakresie badań naukowych lub prac rozwojowych na rzecz obronności i bezpieczeństwa państwa. Dynamiczny rozwój nowoczesnych technologii informatycznych oraz powszechny dostęp do różnorodnych programów komputerowych stwarza możliwość wspomagania różnego rodzaju szkoleń z wykorzystaniem urządzeń symulacji komputerowych, np. jazdy pojazdami w sposób zbliżony do rzeczywistości. W miarę rozwoju technologii informatycznych pojawiły się nowe możliwości. Symulator będący najnowszej generacji rozwiązaniem pozwoli na radykalne zwiększenie efektywności i operatywności szkolonych policjantów. Zastosowana wielowariantowość profili szkoleniowych znacząco rozszerzy kwalifikacje i umiejętności policjantów. Wykorzystanie zaawansowanych algorytmów sztucznej inteligencji pozwoli na wyeliminowanie najdrobniejszych błędów, które w dotychczasowym systemie szkolenia były niemal niemożliwe do wykrycia przez instruktorów prowadzących zajęcia praktyczne. W niniejszym artykule podjęte rozważania oparto na studiach literatury, doświadczeniu i pracy własnej w pełnieniu funkcji kierownika operacyjnego projektu oraz na podstawie własnych obserwacji i rozmów z kierownikami projektów realizowanych na rzecz bezpieczeństwa i obronności państwa w administracji publicznej.

The article presents an innovative tool aimed at counteracting and reducing risks associated with road traffic, including during actions performed by police officers at the scene. This tool is a simulator supporting the training of police officers in the implementation of activities at the site of a road incident, which was established as part of the project of the Police Academy in Szczytno, financed by the National Centre for Research and Development in call for proposals No. 9/2018 for the implementation of projects in the field of scientific research or works development for defence and state security. The dynamic development of modern information technologies and universal access to various computer programs make it possible to support various types of training with the use of computer simulation devices, e.g. driving vehicles in a manner closely resembling reality. As information technology developed, new opportunities have emerged. The simulator, which is a state-of-the-art solution, will dramatically increase the efficiency and operability of police officers undergoing training. The applied multi-variant training profiles will significantly contribute to expanding the qualifications and skills of police officers. The use of advanced artificial intelligence algorithms will make it possible to eliminate the smallest errors, which were almost impossible to detect by the instructors conducting practical classes in the previous training system. The considerations undertaken in this article are based on literature studies, experience and own work in executing the function of an operational project manager and on the basis of own observations and interviews with managers of projects implemented for security and national defence in public administration.

Purpose: The main purpose of this paper is to identify new opportunities for the development of rural areas. A contribution to this should be the combination of modern tools and technologies that affect the improvement of the quality of life and the possibility of creating new jobs in rural areas. Design/methodology/approach: The paper employs the desk research method in the form of an analysis. The analysis of the available literature on the subject on smart villages and the examples of smart villages described in the paper rendered it possible to establish the facts, verify the data and present the results. Findings: The considerations presented in the article indicate that a key element in smart villages is smart human resources that respond to challenges and changes occurring in rural areas. In order to make a real change in a given area, collective action is required rather than individual, and, depending on incentives and local circumstances, these initiatives may prioritise economic, social or environmental issues - or a combination thereof. Practical implications: A common space for development and shared commitment of the rural population enables building social ties as an integral functioning of Smart Villages. Social implications: The needs of the rural community should always come first and the implemented solutions should be adjusted according to these needs, bearing in mind what resources that a given community has. Originality/value: The article is an original approach to the search for intelligent solutions that are meant to improve the development of rural areas and make life easier for rural residents.

A purposeful growth in efficiency of large industrial companies largely depends on a balanced decision-making concerning the content, the cost, and the quality of corporate projects to increase business productivity. A traditional project management methodology does not allow improving all project’s parameters simultaneously. This leads to difficulties in implementing the developed measures and in providing the planned productivity growth. To search balanced decisions in labor productivity projects it is suggested to use an integrated approach, focused on a range of efficient instruments from allied management fields. It is recommended to integrate project man-agement methodology with some instruments of strategic and innovative management, production systems development concepts LEAN, QRM and Agile, human resource and project portfolio management. A model of an integrated approach to labor productivity projects, which was developed and tested, is reasonable to use in large companies to develop hi-tech products and conduct organizational changes.

This study presents a method of computer support for the design of a hydraulic servo dedicated to the aircraft control system. A 3D geometric model of the servo was developed, which enabled the simulation of its kinematics. The paper presents a simulation model of a hydraulic servo that enables simulation of the dynamics of its mechanisms. The servomechanism model takes into account the dynamics of the movement of the distributor slider and the dynamics of the actuator piston rod movement under the influence of forces occurring in the servo. As a result of the simulation, step characteristics and static characteristics of the servo response were obtained. The presented model makes it possible to visualize the dynamics of operation of the prototype servo in various modes of its operation with different parameters of its control. It allows you to quickly and conveniently test the concept of an hydraulic servo and evaluate its functioning.
