LP. Intelligent agents. - Abstract
The parallel story of the evolution of human intelligence and artificial intelligence makes for a fascinating journey, highlighting the distinct but interconnected pathways of biological evolution and technological innovation. This story can be seen as a series of interconnected developments, with each advance in human intelligence paving the way for the next leap forward in artificial intelligence. Human intelligence and artificial intelligence have long been linked, evolving on parallel trajectories throughout history. As humans seek to understand and replicate intelligence, AI has become a field dedicated to creating systems capable of accomplishing tasks that traditionally require human intellect. This book examines the evolutionary roots of intelligence, explores the emergence of artificial intelligence, examines the parallel history of human intelligence and artificial intelligence, tracing their development, interactions, and the profound impact that 'they have had on each other, and envisions future landscapes where human and artificial intelligence converge. Let's explore this history, comparing key milestones and developments in both areas.

BC. Information in society. - Abstract
An analogy between the epistemological and methodological aspects of the activity of intelligence services and certain scientific disciplines, advocating a more scientific approach to the process of collecting and analyzing information within the intelligence cycle. I argue that the theoretical, ontological and epistemological aspects of the activity of many intelligence services are underestimated, which leads to an incomplete understanding of current phenomena and confusion in interinstitutional collaboration. After a brief Introduction, which includes a history of the evolution of the concept of intelligence service after World War II, Intelligence defines the objectives and organization of intelligence services, the basic model of these organizations (the intelligence cycle ) and relevant aspects of information collection and intelligence analysis. In the Ontology section, I highlight the ontological aspects and entities that threaten and are threatened. The Epistemology section includes specific aspects of intelligence activity, with the analysis of the traditional model (Singer) traditionally used, and I expose a possible epistemological approach through the concept of tacit knowledge developed by the scientist Michael Polanyi. The Methodology section contains various methodological theories emphasizing structural analytical techniques as well as some analogies with science, archaeology, business and medicine. The article ends with Conclusions on the possibility of a more scientific approach to the methods of information collection and analysis of intelligence services.

An analysis of the concepts of heuristics and methodological tolerance developed by Lakatos, based on the article "Falsification and methodology of scientific research programs", first published in 1970, then in the work The methodology of research programs scientific, volume I. I analyzed in this text the author's exemplary for the research program of light emission (in quantum physics at the beginning). A detailed example of the concepts is presented by Lakatos in the section "Newton's Effect on Scientific Standards" of the same book. I have also often referred to the book Proofs and Refutations, published by Lakatos in 1976, in which he sets out his heuristic vision through a direct application to the evolution of mathematics. I also referred to articles by other authors for the analysis of the two concepts in Lakatos' vision.

DI. Science libraries. - Abstract
The singularities of general relativity resulting from the resolution of Einstein's equations have been and still are the subject of numerous scientific debates: do there exist singularities in space-time or not? Was Big Bang an initial singularity? If singularities exist, what is their ontology? Is the general theory of relativity a theory that has shown its limits in this case? In this essay I argue that singularities exist and that the theory of general relativity, like any other scientific theory at present, is not valid for singularities. However, as some scientists believe, this does not mean that it should be considered obsolete. After a brief presentation of the specific aspects of the classical Newtonian theory and the theory of special relativity and a brief presentation of the theory of general relativity, the chapter Ontology of general relativity presents the ontological aspects of general relativity. The next chapter, Singularities, is devoted to presenting the singularities leading to general relativity, specific aspects of black holes and the event horizon, including the Big Bang debate as the original singularity and the arguments in favor of the existence of these singularities. In the Ontology of Singularities, I talk about the possibilities of ontological framing of singularities in general and black holes in particular, of the hole argument highlighted by Einstein, and of the arguments presented by scientists according to which it does not there are no singularities and therefore the general theory of relativity is at an impasse. In Conclusions, I briefly describe and summarize the arguments that support my views above.

LP. Intelligent agents. - Abstract
Social media analytics is the art and science of extracting valuable hidden information from large amounts of semi-structured and structured social media data. Algorithms based on social network analytics, natural language processing, complex event processing, and data mining techniques are commonly used by social media analytics software using various specific tools. In positioning a social media analytics program as part of an organization's business intelligence practice or intelligence for an information service, BI can be conceptualized as both a process and a product.

GH. Education. - Abstract
The common thread of Pinocchio’s story is his desire to become a human being. Unlike some creators who approached the adventures of Pinocchio in the context of posthumanism the transhumanism embraces technological progress while strongly defending human rights and individual choice. Pinocchio is aware of his incompleteness: he seeks during the story to become „a real boy.” Human consciousness can refer to things that we do not perceive directly. Pinocchio is a „child” without a mother, created by his father to fill his loneliness. He highlights the current problem of the relationship between man and his creation, out of control.

LJ. Software. - Abstract
Python is a multi-paradigm programming language that pursues a simpler, less cluttered syntax and grammar while giving developers a choice in their coding methodology. In most situations, it is recommended to allocate memory from the Python heap, since the latter is under the control of the Python memory manager. Even when the requested memory is used purely for internal, very specific purposes, delegating all memory requests to the Python memory manager gives the interpreter a more accurate picture of its overall memory footprint. For learning the Python programming language, it is easy to work with memory images in a very specific format.

LP. Intelligent agents. - Abstract
Pinocchio is, above all, what he is not. His identity is often played to the limit, imagined by himself and everyone he meets along the way. Pinocchio is the name of life that is simultaneously inorganic, human and animal. For this reason, it is the possible name of a radical desertion: to identify at the same time with oneself and with someone other than oneself. One question that can be deduced from The Adventures of Pinocchio is whether such an intelligent machine would like to become “human”? In fact, before Pinocchio becomes a real boy, he does everything that real boys do, including the disobedience to their parents.

J. Technical services in libraries, archives, museum. ,L. Information technology and library technology ,LH. Computer and network security. - Abstract
In principle, any node within a blockchain network can propose adding new information to the blockchain. To validate that this addition of information (eg a transaction record) is legitimate, the nodes must reach some form of agreement. This is where a "consensus mechanism" comes into play. In short, a consensus mechanism is a predefined specific (cryptographic) validation method that ensures correct sequencing of transactions on the blockchain. In the case of cryptocurrencies, such sequencing is necessary to address the problem of "double spending" (ie the problem that the same payment instrument or asset can be transferred multiple times if the transfers are not centrally recorded and controlled.

BG. Information dissemination and diffusion. - Abstract
Descriptivist theories attempted to eliminate certain logical contradictions if names were considered definite descriptions. Kripke rejected the validity of these descriptivist theories by arguing that there is no need for a unique description of identity, identifying descriptions can be used even if the referent has not been correctly identified, and a description (as opposed to a name) cannot function as a rigid signifier. Later, descriptivist theories extended this idea of defined description to a set of descriptions or a weighted average of these descriptions.

The use of Big Data presents significant legal issues, especially from the point of view of data protection. The existing legal framework of the European Union, based in particular on Directive no. 46/95/EC and the General Regulation on the protection of personal data, provide adequate protection. But Big Data requires a comprehensive and global strategy. The evolution over time has been from the right to exclude others to the right to control one's own data and, currently, to rethinking the right to (digital) identity.

BF. Information policy - Abstract
Socrates practiced dialectic to obtain knowledge, through the method of oral dialogue, what he called the art of "birth of souls". In Plato, dialectic was a type of knowledge with an ontological and metaphysical role, which is reached by confronting several positions in order to overcome opinion (doxa), a movement from the world of appearances (or the "sensible") to intellectual knowledge (or " the intelligible") to the first principles. For a description, statement, or assertion to be knowledge, it must be a belief, be true, and be justified. A statement of faith is an expression of belief in someone or something. Belief must be true to be knowledge. The definition of knowledge as justified true belief was widely accepted until 1960, when the American philosopher Edmund Gettier provoked major widespread discussion. Scientific knowledge is based on the collection of observable and measurable evidence subject to specific principles of reasoning and experimentation. Despite criticisms of Karl Popper's theory of falsifiability for the demarcation between science and non-science, mainly pseudoscience, this criterion is still very useful, and perfectly valid after its refinement by Popper and his followers. Imre Lakatos' Methodology of Scientific Research Programs is a radical revision of Popper's criterion of demarcation between science and non-science, leading to a new theory of scientific knowledge. In the paper I present my proposal to extend Lakatos' methodology with two new terms, bifurcated programs and unifying programs, with their specific characteristics.

BC. Information in society. - Abstract
In intelligence, epistemology is the study of threat knowledge and how threat is understood in the field of intelligence analysis. Most definitions of intelligence activity do not take into account the fact that the epistemic normative status of the analyzed information is knowledge and not an inferior alternative. The counter-arguments to the epistemological status of intelligence activity are their action-oriented purpose, and their future-oriented content.

The heavy water plant was established under the name of Combinatul Chimic Drobeta, by Decree 400/16.11.1979, under the Inorganic Products Industrial Center (CIPA) Râmnicu Vâlcea. The thermo-electric plant for supplying the heavy water factory with steam was decided to be located in Halânga village, three kilometers from the factory. The process water required for the factory was brought from the Danube, and the hydrogen sulphide used in the process was produced in the plant, through a specific technology, and then compressed, liquefied and stored in special tanks. The works on the heavy water factory at Drobeta Turnu Severin started in 1979, based on a derogatory HCM. The equipment for the heavy water plant was purchased through the Industrial Center for Chemical and Refinery Equipment (CIUTCR). All equipment and facilities that transported hydrogen sulphide had to meet strict quality assurance conditions.

LP. Intelligent agents. - Abstract
Artificial intelligence has progressed to the point where it is an essential component in almost every sector of today's modern economy, with a significant impact on our private, social and political lives. It was founded on the assumption that human intelligence can be described so accurately that a machine can be made to simulate it. This raises philosophical arguments about the mind and the ethics of creating artificial beings endowed with human-like intelligence. Artificial intelligences are a source of a whole new set of problems of explainability, accountability and trust.

LP. Intelligent agents. - Abstract
Artificial intelligence has created unprecedented opportunities, but also new risks. The exponential increase in the capabilities of artificial intelligence models enables previously unattainable levels of value and generalization. However, the opacity of these models has also increased, and their black-box nature makes it difficult, even for experts, to explain the rationale behind their conclusions. This may represent a technological and social critical point, as the risk is real, as evidenced by recent episodes, of training systems being compromised by discrimination biases that have learned from training data. It is therefore possible that learning from digital traces of past decisions can lead to existing invisible biases being incorporated into the resulting patterns, perpetuating them.

David Singer states that the threat is currently the primary focus of intelligence agencies. Intelligence activity can be thought of as the process by which certain types of information are requested, collected, analyzed, and disseminated, and how certain types of covert actions are designed and carried out. The intelligence cycle is a set of processes used to provide useful information in decision making. The cycle consists of several processes. The related field of counterintelligence is charged with thwarting the informational efforts of others.

Association rule learning is a rule-based machine learning method for discovering interesting relationships between variables in large databases. It is intended to identify strong rules discovered in databases using some measures of interest. Based on the concept of strong rules, association rules were introduced to discover regularities between products in large-scale transaction data recorded by supermarket point-of-sale systems. Such information may be used as a basis for decisions regarding marketing activities, such as, for example, promotional pricing or product placements. In addition to the above example from market basket analysis, association rules are used in many fields today, including web mining, intrusion detection, continuous manufacturing, and bioinformatics.

Paul Ricoeur examined a number of different forms of extended discourse, beginning with metaphorical discourse. Narrative discourse is one of the investigated forms, configuring heterogeneous concepts that identify actions at a time when one thing happens not only after something else, but also because of something else in a story or history that can be followed. It recasts physical events as narrative events, which make sense because they tell what happens in a story or history. Narratives are always a synthesis of the heterogeneous concepts that configure the episodes of the story.

From a methodological point of view, both Newton and Einstein, and later Dirac, unreservedly supported the principle of mathematical simplicity in the discovery of new physical laws of nature. They were joined by Poincaré and Weyl. Eduard Prugovecki states that quantum gravity has forced the consideration of some fundamental epistemological questions, which can be identified in philosophy with the mind-body problem and the problem of free will. These questions influenced the epistemology of quantum mechanics in the form of von Neumann's "psycho-physical parallelism" and Wigner's subsequent analysis of the thesis that the "collapse of the wave packet" takes place in the mind of the "observer".

Despite a large number of documents relating to different aspects of the 5G architecture (e.g. individual network functions, interfaces, security functions, different 5G domains, etc.), only a few provide a comprehensive overview. For this, it was necessary to visualize the various components in a modular and general way. Once the comprehensive technical architecture of 5G was defined, and after examining the known weaknesses of the components, it was possible to list the sensitive assets and describe the most relevant threats.

BC. Information in society. - Abstract
Biopower refers to the practice of modern nation-states through an explosion of numerous and diverse techniques for achieving the subjugation of bodies and the control of populations. Foucault used the term to refer specifically to public health practices, among other regulatory mechanisms. Biopolitics is a concept that considers the administration of life and populations of a governed region. Biopolitics produces a generalized disciplinary society and regulatory controls through population biopolitics. Biopolitical inclusion produces geopolitical effects, through the policies of caring for one's own ethnicity, creating the motivations for the incorporation of separatist territories. Biopolitical and geopolitical discourses reinforce and support each other, and can condition each other. Studying these correlations can help us better understand the reason for actions.

BA. Use and impact of information. - Abstract
Despite criticisms of Karl Popper's theory of falsifiability for the demarcation between science and non-science, mainly pseudoscience, this criterion is still very useful, and perfectly valid after its refinement by Popper and his followers. Moreover, even in its initial version, considered by Lakatos as "dogmatic", Popper did not state that this methodology is an absolute criterion of demarcation: a single counter-example is not enough to falsify a theory; moreover, a theory can legitimately be saved from falsification by introducing an auxiliary hypothesis. Compared to Kuhn's theory of revolutions, which he himself later renounced by turning it into a theory of "micro-revolutions", I believe that Popper's demarcation methodology, together with the further development he proposed, including the corroboration and verisimilitude, while imperfect, is not only valid today, but is still the best demarcation methodology. For my argument, I have used Popper's main works dealing with this issue, and his main critics and supporters. After a brief introduction to Karl Popper, and an introduction to the problem of demarcation and the methodology of falsifiability, I review the main criticisms and arguments of his supporters, emphasizing that Popper never equated falsifiability with refutation. Finally, I present my own conclusions on this issue.

GZ. None of these, but in this section. - Abstract
The singularities from the general relativity resulting by solving Einstein's equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their ontology? Is the general theory of relativity a theory that has shown its limits in this case? In this essay I argue that there are singularities, and the general theory of relativity, as any other scientific theory at present, is not valid for singularities. But that does not mean, as some scientists think, that it must be regarded as being obsolete. After a brief presentation of the specific aspects of Newtonian classical theory and the special theory of relativity, and a brief presentation of the general theory of relativity, the chapter Ontology of General Relativity presents the ontological aspects of general relativity. The next chapter, Singularities, is dedicated to the presentation of the singularities resulting in general relativity, the specific aspects of the black holes and the event horizon, including the Big Bang debate as original singularity, and arguments for the existence of the singularities. In Singularity Ontology, I am talking about the possibilities of ontological framing of singularities in general and black holes in particular, about the hole argument highlighted by Einstein, and the arguments presented by scientists that there are no singularities and therefore that the general theory of relativity is in deadlock. In Conclusions I outline and summarize briefly the arguments that support my above views.

GZ. None of these, but in this section. - Abstract
The interpretation of Isaac Newton's texts has raised many controversies to this day. One of the most heated debates is related to the action between two bodies at a distance from each other (gravitational attraction), and to what extent Newton involved God in this case. Basically, most works discuss four types of gravitational attractions in the case of bodies at a distance: direct action at a distance as an intrinsic property of bodies in the Epicurean sense; direct action at a distance divinely mediated by God; action at a distance mediated through a material ether; or action at a distance mediated through an immaterial ether. The purpose of this paper is to argue his own opinion according to which Newton categorically refused the types of direct action as an intrinsic property of bodies, and remote action mediated by a material ether. As for the other two types of action, direct by divine intervention and mediated by an immaterial environment, Newton stated several times that he did not know the exact cause of gravity, but in both cases he implicated God directly in the first case and as being the primary cause (medium/ether being the secondary cause) in the immaterially mediated action. But as an acknowledgment of direct action at a distance might have given some credit to those who thought that gravity might be essential to matter, and consequently to atheism, Newton never openly admitted to accepting the possibility of such an idea. Towards the end of his life, Newton leaned more towards action at a distance mediated by an immaterial ether.

As social media channels move from personal to professional life and permeate daily corporate routines and business workflows, organizations are faced with the need to formulate and implement measurement techniques to help them gain insights from social media interactions and evaluate the success of their own social media initiatives. Social media analytics (social media analytics) is a new and emerging field poised to enable companies to improve their performance management initiatives across various business functions. Whether it's to measure the effectiveness of promotional campaigns, gather information about customer needs and preferences, discern brand perceptions, get feedback on product performance, or to capture data on market trends, social media analytics has the potential to provide useful insights. different lines of business such as marketing and sales, customer relations, public relations and product development.

BH. Information needs and information requirements analysis. - Abstract
Methodology, in intelligence analysis, consists of the methods used to make decisions about threats, especially within the discipline of intelligence analysis. Robert Flood's prismatic theory, referred to by others as methodological pluralism, uses the metaphor to describe creative and transformative thinking, namely a prism that breaks light into its component colors through double refraction. Structural analytic techniques are used to challenge judgment, identify mindsets, overcome biases, stimulate creativity and manage uncertainty.

Over time, general relativity has accumulated several anomalies and discrepancies, indicating the need for better theories of gravity or other ways of approaching it. The ad hoc assumptions introduced into general relativity to explain gravitational singularities based on energetic conditions are not very effective. More detailed assumptions about the content of matter are needed. Many scientists and philosophers have come to the conclusion that singularities must be associated with reaching the limits of the physical validity of general relativity, necessitating the development of a new theory, quantum gravity.
