The interconnected and self-driving vehicles (CAVs) are appearing in a world of human travel, where they promise enhanced safety, better efficiency, and a sustainable approach to transportation. But realizing their potential calls for a complete rethinking of today’s infrastructure and CAVs’ place in it. The research needed for that understanding to happen is very much in its early stages. This article serves as a beginning point for a full-scale study of the issue. It looks at the infrastructure changes that will be required to safely integrate CAVs into our lives, changes that already face several very serious obstacles. It also looks at the future societal and governmental changes the CAVs will force upon us. And it considers all these changes in light of what's become an essential landscape for the CAVs: the cybersecurity threat to the millions of lines of code the vehicles rely upon for their safe functioning. At the end, we'll also flag some gaps in what's known so far and what those gaps could mean for a future informed by the knowledge of the past.

Reducing the time and cost of aircraft creation can be achieved by improving the accuracy, informativity, and efficiency of flight research results on free flying dynamically similar models (FDSM). In particular, this is ensured by the development, improvement, generalization, and application of theoretical and methodological foundations for the creation of FDSM. This paper is structured from these positions. It does not reveal all the peculiarities of the design, manufacture, and testing of FDSM but shows the influence and dependence of altitude-velocity limitations of physical modelling problems on the main parameters of FDSM. At the same time, a literature review was performed to study and analyze the achievements and problems of physical modeling of aircraft flight on FDSM. The conditions and scales of similarity used in the design, manufacture, ground and flight tests of FDSM, and flight research are considered. The influence on the main parameters of FDSM of modelling problems, together with similarity conditions and the system of relations of parameters of FDSM, of the full-scale aircraft and environment; design conditions; technological limitations; flight-technical requirements; and operational limitations is emphasized. It is established that if mass is taken as the objective function in the design of an FDSM, then in order to achieve its minimum, one should strive to create an FDSM with the minimum possible linear sizes. To take into account the auto-model limitations of modelling problems, a special method for predicting flight characteristics and scientific-research capabilities of an FDSM has been developed and presented.

With the fast-paced development of the aviation industry, air traffic is also increasing, leading to the problem of how to control the traffic safely, and effectively, and increase the capacity of airspace. Therefore, numerous approaches have been taken to cope with this, including optimal models - an effective approach to addressing airspace congestion issues worldwide. However, the application of these models in Vietnam remains relatively limited. In this research, we aim to address the issue of airspace congestion and how to enhance safety and efficiency by developing an algorithm capable of automatically detecting and resolving conflicts. This is achieved by adjusting the entry time and flight level (FL) of aircraft operating within the Wind-Optimal Track Network (WOTN) model that we have developed for the Ho Chi Minh Flight Information Region (HCM FIR). The research contributes to the advancement of air traffic management (ATM) systems, particularly in the context of HCM FIR, minimizing air traffic controller (ATC) workload, and offering valuable insights for enhancing operational efficiency and safety in the airspace.

Purpose: The article attempts to answer the following research questions: What are the main challenges associated with implementing a teal organization in the sales departments of marketing agencies? What actions were taken to shape the attitudes and values desired by the studied company, which are characteristic of the teal organization model? What benefits were achieved as a result of the actions taken? Design/methodology/approach: Attempting to answer the research questions required a literature review and conducting research procedures. The case study method was used in the research process. The aim of the study was to describe a typical case of implementing the teal organization model in the studied company. Additionally, the research employed direct observation techniques, surveys, interviews, and organizational documentation. Findings: The effective implementation of the teal organization model requires methodical actions that focus the efforts of organizational participants around the values and attitudes desired by the organization. Identifying the key values and attitudes of a teal organization and recognizing gaps in these values and attitudes within the sales department enabled actions that contributed to transforming the existing organization into a teal organization. Practical implications: The analysis of actions taken by the studied company leads to the conclusion that they contributed to raising employees' awareness of the teal organization principles and embedding its values and assumptions within the organization. Considering the research findings, it can be assumed that the teal organization model has a place in modern management. This assumption is based on the desire to work in an environment that nurtures human values; the employees' contribution, their engagement, feedback culture, and trust. Barriers in implementing the teal organization model often include a lack of trust in the concept, which relies on empowering employees and relinquishing traditional control over the work process. Originality/value: The innovation lies in highlighting the need to incorporate values and attitudes characteristic of the teal organization concept in the implementation process, identifying actions that contribute to shaping these values and attitudes, and determining how an effectively implemented teal organization can impact the development of sales departments in marketing agencies.

Zagrożenia są stałym elementem rzeczywistości, ich wielorakość oraz ewolucyjny charakter wymagają ciągłego efektywnego monitorowania, ujawniania i stosownego podejścia do nich. System wykrywania zagrożeń, ostrzegania, powiadamiania i alarmowania o nich stanowi fundament realnych przygotowań ludności cywilnej do zachowania się w trakcie niebezpieczeństwa. Bez ustawicznego monitoringu oraz klarownych, przejrzystych (znanych) komunikatów ostrzegawczych i sygnałów alarmowania społeczeństwo nie jest w stanie zachować się tak, by podjąć dalej adekwatne zachowania, by ustrzec się przed konsekwencjami rzeczywistych zagrożeń dla jego egzystencji. Jasno określone zasady funkcjonowania systemu oraz oczekiwanej reakcji pozwolą na stosunkowo szybkie i właściwe podjęcie zachowań w odpowiedzi na zaistniałe zagrożenia, a tym samym na możliwie najbardziej efektywne reagowanie na nie. Kwestia ta stanowi istotne ogniwo ustawy o ochronie ludności i obronie cywilnej, na który to dokument polskie społeczeństwo oczekuje od maja 2009 roku. Ustawa ma niebawem wejść do polskiego porządku prawnego, dlatego warto mówić o szczegółowych jej zapisach. Dotyczy bowiem zarówno zabezpieczenia ludzi, zwierząt, mienia, środowiska w różnych stanach funkcjonowania państwa. Świadomość obywateli ma kluczowe znaczenie. Ustawa o ochronie ludności i obronie cywilnej nakłada obowiązek na organy ochrony ludności dotyczący organizacji systemów monitorowania zagrożeń oraz powiadamiania, ostrzegania i alarmowania ludności w przypadku wystąpienia zagrożeń. W kontekście poruszanego problemu (system wykrywania zagrożeń, ostrzegania, powiadamiania i alarmowania o zagrożeniach) nie sposób nie podjąć rozważań wokół znowelizowanego rozporządzenia Rady Ministrów w sprawie systemów wykrywania skażeń i powiadamiania o ich wystąpieniu oraz właściwości organów w tych sprawach. Dokument ten określa organizację i warunki przygotowania oraz sposób funkcjonowania systemów obserwacji, pomiarów, analiz, prognozowania i powiadamiania o skażeniach na terytorium Rzeczypospolitej Polskiej oraz właściwość organów w tych sprawach.

Threats are a permanent feature of reality, their multiplicity and their evolving nature require continuous effective monitoring, disclosure and an appropriate approach to them. A system of threat detection, warning, notification and alerting of threats is the foundation of viable preparations of the civilian population to behave during an emergency. Without continuous monitoring and clear, transparent (known) warning messages and alert signals, the public is unable to behave in such a way as to take further adequate behaviour to guard against the consequences of real threats to its existence. Clearly defined rules for the operation of the system and the expected response will allow behaviour to be taken relatively quickly and appropriately in response to the threats that arise, and thus to respond to them as effectively as possible. This issue is an important link in the Law on Civil Protection and Civil Defence, which Polish society has been waiting for since May 2009. The Act is about to enter the Polish legal order, so it is worth talking about its detailed provisions. This is because it concerns both the security of people, animals, property and the environment in the various states of the state. Citizen awareness is of key importance. The Law on Civil Protection and Civil Defence imposes an obligation on civil protection authorities to organise systems for monitoring threats and notifying, warning and alerting the population in case of threats. In the context of the issue at hand (threat detection, warning, notification and alarming system for threats), it is impossible not to take up considerations around the amended regulation of the Council of Ministers on systems for the detection of threats and notification of their occurrence and the competence of authorities in these matters. This document defines the organisation and conditions for the preparation and functioning of systems of observation, measurement, analysis, forecasting and notification of contamination on the territory of the Republic of Poland and the competence of the authorities in these matters.

This article describes supply and demand through the spatial and non-spatial dimensions of the users and providers of ride-hailing services in the higher education area. The structural equation modeling method determines the relationship between variables based on a perception survey of 200 users and 200 ride-hailing service providers in the Tembalang higher education area, Semarang, conducted from 2020-2021. The modeling results show that there is an insignificant spatial and non-spatial relationship. The non- spatial dimension in both users and ride-hailing providers influences the moderating of both spatial dimensions. The development of higher education institutions in peri-urban areas creates new growth poles in line with the evolution of digital platforms that dictate physical geographies due to the fusion of non-spatial conditions. Reconciling the public transportation system with campus-based operational adjustments, appropriate fares, and fees will provide more equal opportunities for campus residents to engage and succeed in higher education.

Road accidents are an inevitable part of road traffic. Those involving trucks and vulnerable road users are especially tragic. Multiple solutions are proposed to deal with this problem. Among them is the idea of using camera-monitor systems instead of traditional exterior mirrors. The paper presents the results of a pilot study conducted in the practice yard using two trucks. One was equipped with the camera-monitor system replacing exterior side mirrors, and the other was equipped with traditional mirrors. The systems’ usability was compared in the practice yard based on two scenarios. Eye tracking was used as a method of perception assessment to assess whether the driver noticed a potentially dangerous situation and objectively measure the time needed for the driver to scan the surroundings. The number and duration of detected eye movements were measured and analyzed. The results for both types of devices for indirect vision were compared. This made it possible to determine the number of obstacles that the driver overlooked. The results for both types of devices were similar and suggest the need to supplement existing devices for indirect vision with additional systems that could help drivers detect hazards. However, the comparison of indirect fields of view suggested a slight superiority of the camera-monitor system.

PL
Artykuł przedstawia zagadnienia związane z polityką zbrojeniową jako częścią polityki państwa, tj. całościowo określającą kierunki rozwoju i interwencji państwa w tym obszarze. Autor formułuje wnioski dla polskiej polityki zbrojeniowej, skupiając się na systemowym podejściu do jej ustanawiania i realizacji oraz strategicznym zarządzaniu państwem. Prezentowane ustalenia badawcze podzielone są na następujące zasadnicze części: istota polityki zbrojeniowej; aspekty instytucjonalne; krajowy potencjał przemysłowy i zdolności produkcyjne; badania, rozwój i innowacje. Podnoszone są kwestie planowania i programowania działań państwa zgodnie z określonymi priorytetami oraz interesami narodowymi, w tym w obszarze inwestycji w rozwój sprzętu wojskowego i technologii oraz określania kierunków rozwoju krajowego przemysłu obronnego, zwiększenia zdolności produkcyjnych, krajowej suwerenności (technologicznej oraz decyzyjnej), jak również wzmocnienia systemu badań i rozwoju w dziedzinie obronności. Autor przytacza także postanowienia dokumentów strategicznych krajowych i sojuszniczych. Celem artykułu jest analiza polityki zbrojeniowej państwa w perspektywie strategicznej na przykładzie Polski. Główny problem badawczym zawarty został w pytaniu: Jakie reperkusje dla bezpieczeństwa narodowego niosą za sobą działania państwa lub ich brak w zakresie polityki zbrojeniowej? Hipoteza badawcza stawiana przez autora brzmi, iż: Wdrożenie w kraju sformalizowanej polityki zbrojeniowej w postaci dokumentu strategicznego przyczyniłoby się do podniesienia efektywność zarządzania dziedzinami obronności państwa i rozwoju gospodarczego, w tym w szczególności modernizacji technicznej sił zbrojnych i przemysłu zbrojeniowego. Ustanowienie polityki zbrojeniowej pozwoliło by więc, aby konieczny (w obliczu zagrożenia) proces zbrojenia, nie doprowadził do załamania finansowego państwa (w wyniku kierowania zamówień za granicę), a stał się motorem rozwoju rodzimej gospodarki opartej o wysokie technologie. Do opracowania artykułu wykorzystano metody przeglądu literatury oraz wnioskowania. Artykuł opiera się o dotychczas upublicznione dane i publiczne dokumenty, jak również publikacje stanowiące głos w dyskusji w obszarze podejmowanej problematyki.

The article presents issues related to armaments policy as part of state policy, i.e. comprehensively defining the directions of development and state intervention in this area. The authorformulates conclusions for Polish armaments policy, focusing on the systemic approach to its establishment and implementation and strategic management of the state. The presented research findings are divided into the following main parts: the essence of armaments policy; institutional aspects; national industrial potential and production capacity; research, development and innovation. Issues of planning and programming state activities in accordance with specific priorities and national interests are raised, including in the area of investment in the development of military equipment and technology and determining the directions of development of the national defence industry, increasing production capacities, national sovereignty (technological and decision-making autonomy), as well as strengthening the defence research and development system. The author also refers to the provisions of national and allied strategic documents. The aim of the article is to analyze the state’s armament policy from a strategic perspective on the example of Poland. The main research problem is contained in the question: what are the repercussions for national security of the state’s actions or lack thereof in the field of armaments policy? The research hypothesis put forward by the author is that the adoption national an armament policy in the form of a strategy would contribute to increasing the effectiveness of management of the state’s defence and economic development, including the technical modernization of the Armed Forces and the defence industry. The establishment of an armament policy would therefore allow the necessary (in the face of a threat) armament process not to lead to the financial collapse of the state (as a result of directing orders abroad), but to become a driving force for the development of the domestic economy based on high technologies. The article was developed using literature review and reasoning methods. It is based on previously published data, public documents, and expert studies.

Ensuring effective protection of the population in an emergency requires the efforts of public administration bodies and other social and economic entities performing tasks in the field of security and defence. A special role in civil protection activities is played by: civil defence, the Police, the Border Guard, the State Fire Service, units of the Volunteer Fire Brigade, other rescue units and various specialised agencies, inspections, and services. The subject of crisis management is more and more often discussed and publicized in the public debate and in various publications. It is necessary to continuously adapt and improve national security management, adequately to contemporary challenges and threats, among others, by integrating many dispersed, side-by-side solutions. The article discusses the current organizational and legal solutions in this area, which allowed to answer the question whether the activities aimed at improving the internal conditions of security are aimed at creating an integrated national security management system. The aim of the article is to analyse the functioning of the crisis management system in Poland, and in particular the principles of operation of crisis management teams in emergency situations, taking into account the legal and institutional conditions of crisis management bodies in local government structures. For the purposes of this study, the following research problem has been formulated: How should crisis management teams work in the planning, decision-making and functional process at individual levels of administration in the event of threats? The basis for the development of the article were relevant legal acts and literature on the subject.

The Multi-Domain Operations (MDO) concept aims to prepare, plan, coordinate, and carry out synchronised activities across all domains and environments on a large scale and swiftly. This is done in collaboration with other instruments of power, stakeholders, and actors, following the principles of Unity, Interconnectivity, Creativity, and Agility. This study emphasises the potential of applying the principles of MDO in urban environments (UE) to further enhance MDO’s effectiveness. More precisely, it presents two further principles, namely Understanding and Interaction, which enhance the overall MDO, and highlight the absence of a crucial aspect of the “digital backbone”, specifically in relation to interaction.

Odnawialne źródła energii oraz tzw. zielony wodór, odegrają istotną rolę w dekarbonizacji gospodarki. Mając na uwadze dynamiczny wzrost udziału OZE w bilansie energetycznym, obserwowany zarówno w kraju, jak i UE i zakładając, zgodnie z aktualnymi prognozami krajowymi i unijnymi, dalszą ekspansję OZE, należy się spodziewać, że wykorzystanie istniejących sieci gazowych dla transportu gazowych paliw odnawialnych, będzie pomocne w spełnieniu zakładanych celów polityki energetycznej. Wprowadzenie gazowych paliw odnawialnych, w tym wodoru, do istniejących sieci gazowych, musi być poprzedzone szczegółową analizą. W artykule podjęto próbę oceny wpływu domieszek wodoru w gazie ziemnym na problem rozliczania paliw gazowych w jednostkach energii w systemie dystrybucyjnym. Przybliżono otoczenie regulacyjne dotyczące tego obszaru. Następnie na wytypowanym fragmencie gazowego systemu dystrybucyjnego przeprowadzono analizę wpływu wprowadzenia wodoru do sieci gazowej na rozliczenie paliw gazowych w jednostkach energii w trzech wariantach. W wyniku tej analizy m.in. oszacowano zmiany strumienia dostarczanego paliwa gazowego do odbiorcy w zależności od stężenia wodoru.

Renewable energy sources, and the so-called green hydrogen, Will play an important role in the decarbonization of the economy. Given the dynamic growth of the RES participation in the energy balance, observed both domestically and in the EU, and assuming, in accordance with current national and EU forecasts, further expansion of RES, it is expected that the use of existing gas networks for the transportation of gaseous renewable fuels, will help achieve the assumed energy policy goals. The introduction of gaseous renewable fuels, including hydrogen, into existing gas networks must be preceded by a detailed analysis. The article attempts to assess the impact of hydrogen admixtures in natural gas on the problem of accounting for gaseous fuels in units of energy in the distribution system. The regulatory environment pertaining to this area is approximated. Subsequently, an analysis of the impact of introducing hydrogen into the gas network on the billing of gaseous fuels in units of energy in three variants was carried out on a selected part of the gas distribution system. As a result of this analysis, among other things, changes in the stream of gaseous fuel delivered to the customer depending on the concentration of hydrogen were estimated.

This paper presents a comparative thermodynamic and economic analysis of combined heat and power (CHP) plants utilizing Small Modular Reactors (SMRs) and High Temperature Gas-cooled Reactors (HTGRs) designed for use in largescale and distributed power generation. The study focuses on the differences between these two reactor types in CHP applications, highlighting their respective efficiencies and economic viabilities. The analysis reveals that CHP plants with HTGR reactors demonstrate significantly higher thermodynamic and economic efficiency compared to those with SMR reactors. This superiority is attributed to three main factors: the higher electrical efficiency of HTGR-based plants, lower investment costs for HTGR reactors, and consequently, more cost-effective electricity production in HTGR-based CHPs. The paper provides detailed thermodynamic calculations and economic assessments, including unit costs of heat production under various scenarios. It also discusses the advantages of locating these small-scale nuclear CHP plants closer to consumers, eliminating the need for extensive transmission networks. The findings suggest that HTGR-based CHP plants offer a more promising solution for future energy systems, including those operating in local power structures, particularly when considering gas-gas technology implementations that do not require water for operation, addressing a key limitation of both SMR and HTGR systems in conventional configurations.

W artykule przedstawiono porównawczą analizę termodynamiczną i ekonomiczną elektrowni skojarzonych (CHP) wykorzystuj ących małe reaktory modułowe (SMR) i wysokotemperaturowe reaktory chłodzone gazem (HTGR) przeznaczone do stosowania W dużych i rozproszonych elektrowniach. Badanie koncentruje się na różnicach między tymi dwoma typami reaktorów W zastosowaniach CHP, podkreślając ich dpowiednie sprawności i opłacalność ekonomiczną. Analiza ujawnia, że elektrownie CHP z reaktorami HTGR wykazują znacznie wyższą sprawność termodynamiczną i ekonomiczną W porównaniu z reaktorami SMR. Ta wyższość przypisuje się trzem głównym czynnikom: wyższej sprawności elektrycznej elektrowni opartych na HTGR, niższym kosztom inwestycyjnym reaktorów HTGR, a w konsekwencji bardziej opłacalnej produkcji energii elektrycznej w elektrowniach CHP opartych na HTGR. W artykule przedstawiono szczegółowe obliczenia termodynamiczne i oceny ekonomiczne, W tym jednostkowe koszty produkcji ciepła w różnych scenariuszach. Omówiono w nim również zalety lokalizacji tych małych elektrowni jądrowych CHP bliżej odbiorców, co eliminuje potrzebę rozległych sieci przesyłowych. Wyniki sugeruj ą, że elektrownie CHP oparte na HTGR oferują bardziej obiecujące rozwiązanie dla przyszłych systemów energetycznych, W tym tych działających W lokalnych strukturach energetycznych, szczególnie przy rozważaniu wdrożeń technologii gaz-gaz, które nie wymagają wody do działania, rozwiązując kluczowe ograniczenie zarówno systemów SMR, jak i HTGR w konwencjonalnych konfigurac ach.

Wyobraź sobie, że masz strategię firmy, którą nie tylko da się oprawić w ramkę i powiesić w gabinecie, ale która naprawdę działa. Tzn. nie tylko „istnieje”, ale faktycznie prowadzi ludzi w organizacji w tym samym kierunku. I teraz pytanie: jak to osiągnąć? Wbrew pozorom, odpowiedź nie leży w kolejnych warsztatach strategicznych, ale... w procesie S&OP.
