FG. Local government. - Abstract
In the contemporary landscape of public administration, significant changes have taken place, driven by the need for efficiency, transparency and increased citizen involvement. Three key concepts encapsulate these changes: New Public Management, e-governance, and the ubiquitous role of social media. Each represents a transformative approach to governance, collectively shaping a more responsive and accountable public sector. This book explores the significant contributions of social media to democratic governance models, the realization of the principles of new public management and e-governance. It examines how social media facilitates transparency, improves accountability and citizen engagement, and encourages collaborative governance, thereby redefining traditional models of public administration.

Sfetcu, Nicolae

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.

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.

GD. Organizations. - Abstract
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.

BC. Information in society. - Abstract
About the existing analogy between the epistemological and methodological aspects of the activity of information services and some scientific disciplines, advocating for a more scientific approach to the process of gathering and analyzing information within the information cycle. I affirm that currently the theoretical, ontological and epistemological aspects, in the activity of many information services, are underestimated, causing incomplete understanding of current phenomena and creating confusion in inter-institutional collaboration. After a brief Introduction, which includes a history of the evolution of the intelligence service concept after the Second World War, in Intelligence Activity I define the objectives and organization of intelligence services, the basic model of these organizations (the information cycle), and the relevant aspects of gathering information and information analysis. In the Ontology section I highlight the ontological aspects and entities that threaten and are threatened. The Epistemology section includes aspects specific to the information activity, with the analysis of the main model (Singer) traditionally used, and exposes a possible epistemological approach through the prism of the concept of tacit knowledge developed by the scientist Michael Polanyi. In the Methodologies section I present various methodological theories with an emphasis on structural analytical techniques, and some analogies with science, archaeology, business and medicine. The paper ends with the Conclusions regarding the possibility of a more scientific approach to the methods of gathering and analyzing information within the intelligence services.

Due to the special working conditions in the heavy water plant, an extensive research and program has been developed for the operational safety of the installations, based on specific action methodologies and in situ experimental programs for the evaluation of the long-term behavior of materials and installations. After December 1989, the operation of the modules was stopped for about three years, for the modernization of the technological equipment and the surveillance and environmental protection systems. In September 2015, the production of heavy water was stopped and the plant staff was laid off.

Big data security involves adhering to the concepts of right and wrong ethical behavior with respect to data, especially personal data. Big data ethics focuses on the collectors and disseminators of structured or unstructured data. Information security and privacy is supported, at EU level, by extensive documentation, which seeks to find concrete solutions to maximize the value of information without sacrificing fundamental human rights. The European Data Protection Authority (EDPS) supports the right to privacy and the right to the protection of personal data respecting human dignity.

The life cycle of an AI system includes several interrelated phases, from its design and development (including subphases such as requirements analysis, data collection, training, testing, integration), installation, implementation, operation, maintenance and disposal. Given the complexity of artificial intelligence (and information systems in general), several models and methodologies can be defined to manage this complexity, especially in the design and development phases, such as agile, waterfall or spiral software development , rapid and incremental prototyping. The AI lifecycle defines the phases an organization should follow to take advantage of AI techniques and specifically machine learning models to achieve practical business value.

LA. Telecommunications. - Abstract
The 5G architecture presented here resulted from the analysis of various publicly available reports published by standards, research and scientific bodies. This task aimed to establish a common and coherent understanding of the components of the 5G architecture. 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.

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.

DI. Science libraries. - Abstract
Throughout the Second World War, the Romanian secret services collected information on the location of German units in the country. The officers from the conspiratorial group for the return of arms against Germany increase the number of Romanian units present in the capital, in order to be able to face the Germans. A clandestine inter-allied mission was parachuted into Bucharest and secretly hosted by General Constantin Sănătescu. Following the success of the German offensive on the Iasi-Chisinau alignment, the conspiratorial group decided to speed up preparations. On August 20, Michael I and the group of soldiers in the conspiracy set the date of action for August 26. On the night of August 21, in secret, the opposition members agreed to this date. However, learning that Marshal Antonescu intended to return to the front on August 24, King Mihai was forced to change the date to August 23, 1944.

The Internet has completely changed our way of life, being considered one of the most beneficial technological advances of the 21st century. Everything is now sold and bought on the Internet, including entertainment. The internet makes the world smaller because we could order or trade anything worldwide. And in this virtual society we are all commentators, editors and creators. Can you imagine what life would be like now without the Internet? Close your eyes for a minute and think about what life was like before the Internet. For some, the Internet is the ideal opportunity to escape from reality, while for others it is the best opportunity to socialize and make friends with people from all over the world. Personal stories become public; local problems become global.

The term Big Data refers to the extraction, manipulation, and analysis of data sets that are too large to be processed routinely. Because of this, special software and, in many cases, also specially dedicated computers and hardware equipment are used. In general, these data are analyzed statistically. Based on the analysis of the respective data, predictions are usually made of groups of people or other entities, based on their behavior in various situations and using advanced analytical techniques. In this way, trends, needs and behavioral developments of these entities can be identified.

BC. Information in society. - Abstract
The war in Ukraine fundamentally reshaped great power politics and the global economy. Here's what this means for the green transition. The Russian invasion of Ukraine is already a humanitarian disaster, bringing suffering and chaos to millions of people. It also fundamentally reshaped great power politics and the global economy almost overnight. Set against a backdrop of a rising China, reborn variants of COVID, jittery energy markets and an increasingly ineffective US superpower, the Ukraine crisis has made one thing clear: we are in a new geopolitical reality, in that the old platitudes and policies no longer apply. In this context, the need for a redoubled commitment to the values of an inclusive, sustainable and secure green economic transition is stronger than ever. But how can we navigate these chaotic and uncertain times and best focus our efforts towards a greener and fairer future? Here we identify five emerging macro trends that are likely to have a huge impact on the prospects for green economic reform in the coming years.

In June 1941, Romania entered the Second World War on the side of the Axis and against the USSR, hoping to regain the lost territories. On June 22, 1941, the German and Romanian armies began the campaign against the Soviet Union through "Operation Munich", the Romanian army being motivated by the desire to take back Bessarabia and Bucovina from the USSR. On August 1, 1943, the Allies bombed the oil fields and refineries at Ploiesti (Operation Tidal Wave). After the Battle of Stalingrad from August 23, 1942 to February 2, 1943, the Soviet army began to advance and, in March 1944, reached the territory of Romania. Romanian troops participated in the war alongside the Axis in the German Army Group under the name "Southern Ukraine". Marshal Antonescu, convinced of the impossibility of stopping the Soviet assault, on the night of August 21 asked Ambassador Manfred von Killinger to commit all German reserves to support the front, and the next day, on August 22, he informed the Romanian government of his intention to continue fighting alongside Nazi Germany.

AZ. None of these, but in this section. - Abstract
The main biographical source about Plato, according to the testimony of the Neoplatonist Simplicius, would have been written by the disciple Xenocrates, but unfortunately it has not reached us. The earliest surviving biography of Plato, De Platone et dogmate eius, is by a second-century Latin author, Apuleius. All other biographies of Plato were written more than five hundred years after his death. The Greek historian Diogenes (2nd and 3rd centuries) is the author of a series of biographies of Greek philosophers (Lives of the Philosophers) in which he refers to the life of Plato. He would also have written a funeral eulogy for Plato. Other early biographers of Plato are Olympiodorus the Younger in the 6th century and an anonymous source. An important source on Plato's life is his very philosophical dialogues, thirteen letters (possibly spurious though, except perhaps Letters VII and VIII), Aristotle's writings, a fragment of the History of the Philosophers (Syntaxis ton philosophon) by the Epicurean Philodemus of Gadara in 1st century BCE, the anonymous Prolegomena writings on Platonic philosophy traditionally attributed to Olympiodorus, the Suda, 10th century, and Plutarch's Life of Dio, 1st-2nd century.

IG. Information presentation: hypertext, hypermedia. - Abstract
The essay traces the various approaches that researchers have tried in studying the role of intelligence in national and international politics. It considers the many methodological and epistemological strategies that have characterized the study of "intelligence" over the past 50 years and argues that, from its inception, "intelligence" studies have been characterized by interdisciplinarity and openness against different conceptual approaches. Historians, political scientists, sociologists and professionals have all contributed to the burgeoning field of research on intelligence issues. In conclusion, it can be said about intelligence that interdisciplinary research can be one of the biggest advantages of this new subfield and it can be argued the need for an expansion and deepening of the agenda of intelligence studies.

The enterprise ontology makes a clear distinction between the datalogic, infologic, and core layer of blockchain transactions and smart contracts. The OntoClean methodology analyzes ontologies based on formal, domain-independent properties of classes (metaproperties), being the first attempt to formalize the notions of ontology analysis for computer systems. Notions are drawn from philosophical ontology. In the Semantic Web, a property is a binary relationship. The distinction between property and class is subtle. Thus, a metaproperty is a property of a property or class.

BC. Information in society. - Abstract
The Republic was written approximately between 380 and 370 BCE. The title Republica is derived from Latin, attributed to Cicero, who called the book De re publica (On Public Affairs), or even as De republica, thus creating confusion as to its true meaning. The Republic is considered an integral part of the utopian literary genre. The second title, Peri dikaiou (περὶ δικαίου, On justice), may have been included later. The central theme of the book is justice, argued with the help of several Platonic theories, including the allegorical myth of the cave, the doctrine of ideas, dialectics, the theory of the soul, and the project of an ideal city. The Republic is considered by many academics to be the greatest philosophical text ever written, being the most studied book in top universities.

DF. Government libraries. - Abstract
A small guide to political concepts for politicians and activists. Politics is the process of making decisions by groups of people. The term applies to civil governments, but this process has been observed in all interactions between human groups, including corporate, academic, and religious institutions. It consists of "social relations involving authority or power" and refers to the regulation of political units, and to the methods and tactics used to formulate and implement policy. Samuel Gompers' maxim, often paraphrased as "Reward friends and punish enemies," refers to two of the five types of power recognized by social psychologists: incentive power (the power to reward) and coercive power (the power to punish). The other three powers derive from these. The power of legitimacy, the power of a policeman or decision maker, is the power given to a person by a recognized authority to impose standards of behavior. Legitimacy power is similar to coercive power in that unacceptable behavior is punished more or less directly. The power of decision is held by people by virtue of certain skills or attitudes. Fulfilling the desire to feel like a celebrity or a hero is the reward for obedience. This is an example of incentive power where a person rewards himself. The power of the expert derives from education and experience. It should be noted that the power of the expert is conditional on the circumstances.

The modern town of Drobeta Turnu Severin has a relatively new history. It made its appearance on the map of Romania and on that of the world following General Pavel Kiseleff’s decree on the 22nd of April, 1833. The town got its name from the majestic remains of the Severin Fortress which used to look down the Danube and surrounding region at some ancient times. It was erected following a pre-established plan, with wide streets falling perpendicularly onto the Danube or running parallel to it. Drobeta Turnu Severin has warm summers and mild winters, meaning the city is home to magnolia trees, Caucasian nut trees, and gingko biloba as well as the almond trees, figs, lilacs, lindens, and chestnut trees more common throughout Europe. The museum of the Iron Gates Hydropower Station together with the Turbine Hall, the Vodita Monastery, as well as the St. Ann Monastery of Orsova can be easily reached from Turnu Severin. It is from this region that the wonderful area of Cazane becomes accessible both by water and by land. ,,Turnu Severin shows itself in the sunset as in the middle of a decor. Widened, the Danube cuts a curve in the Romanian bank and pushes the town up on a top coverd with trees, the thicket of which discloses overlapped houses enveloped in red hallow dies… A western town with beautiful buildings, great schools, wide and straight streets…”

Book Review: Taleb, Nassim Nicholas (2007), The Black Swan: The Impact of the Highly Improbable, Random House, ISBN 978-1400063512 The book tackles subjects related to knowledge and ways of life, with elements of fiction and anecdotes from the author's personal life, starting from literary aspects to scientific and mathematical ones. The focus is on "our blindness to randomness, especially large deviations." The black swan theory was developed by Nassim Nicholas Taleb to explain the disproportionate role of hard-to-predict rare events, the inconsistency of scientific methods in calculating the probability of rare events due to the nature of small probabilities, and people's biases towards uncertainty and the massive role of a rare event. Taleb suggests that businessmen use the "barbell strategy" for investing that he himself used, which consists of avoiding medium-risk investments and placing 85-90% of the money in the safest instruments available and the remaining 10- 15% in highly speculative business.

LC. Internet, including WWW. - Abstract
On the necessity and usefulness of developing a specific philosophy for blockchain technology, emphasizing ontological aspects. After an Introduction which highlights the main philosophical orientations of this emerging technology, in Blockchain technology I explain how the blockchain works, analyzing the directions of ontological development of this technology in Design and modeling. The next section is dedicated to the main application of blockchain technology, Bitcoin, with the social implications of this cryptocurrency. There follows a section of Philosophy in which I identify blockchain technology with the concept of heterotopia developed by Michel Foucault and interpret it in light of the scoring technology developed by Nelson Goodman as a scoring system. In the Ontology section, I present two paths of development that I consider important: a Narrative Ontology, based on the idea of order and structure of history transmitted through the narrative history of Paul Ricoeur, and the system of Business Ontology based on concepts and business models, specific to the Semantic Web, which I consider to be the most developed and which will probably become the formal ontological system, at least with regard to the economic and legal aspects of blockchain technology. In Conclusions, I talk about future directions in the development of blockchain technology philosophy in general as an explanatory and robust theory from a phenomenologically consistent perspective, which allows for testability and ontologies in particular, arguing for the need of the global adoption of an ontological system in order to develop transversal solutions and make this technology profitable.

DI. Science libraries. - Abstract
The interpretation of Isaac Newton's texts has caused controversy to this day. One of the most heated debates concerns the action between two bodies distant from each other (gravitational attraction), and the extent to which Newton involved God in this case. Practically, most articles deal with four types of gravitational attractions in the case of distant bodies: direct action at distance as an intrinsic property of bodies in the Epicurean sense of the term; direct action at a distance divinely mediated by God; action at a distance mediated by a material ether; or action at a distance mediated by an immaterial ether. The purpose of this article is to argue that Newton categorically rejected the types of direct action as an intrinsic property of bodies and action at a distance mediated by a material ether. Regarding the other two types of actions, direct by divine intervention and mediated by an immaterial environment, Newton repeatedly said that he did not know the exact cause of gravity, but in both cases he had directly involved God, directly in the first case. and as the primary cause (the environment/ether being the secondary cause) in immaterial mediated action. But since the recognition of direct action at a distance might have given some credence to those who thought that gravity could be essential to matter, and therefore to atheism, Newton never openly recognized the possibility of such idea. Toward the end of his life, Newton leaned more toward action at a distance mediated by an immaterial ether.

DI. Science libraries. - Abstract
One of the disputed controversies on the priority of scientific discoveries is that of the law of universal gravitation, between Isaac Newton and Robert Hooke. Hooke accused Newton of plagiarism, of taking up his ideas expressed in earlier works. I'm trying to show, based on previous analysis, that both scientists were wrong: Robert Hooke because his theory was basically just ideas that would never have materialized without Isaac's mathematical support Newton; and the latter was wrong not to recognize the ideas of Hooke in the elaboration of the theory of gravity. Furthermore, after Hooke's death and his accession to the presidency of the Royal Society, Newton removed all traces of former president Robert Hooke from the institution. For this, I detail the accusations and arguments of each of the parties, and how this dispute was perceived by the contemporaries of the two scientists. I end the paper with the conclusions drawn from the content.

DZ. None of these, but in this section. - Abstract
About the main psychological and philosophical aspects detached from the film Solaris directed by Andrei Tarkovski, as well as the cinema techniques used by the director to convey his messages to the spectator. In the "Introduction" I briefly present the relevant elements of Tarkovski's biography and an overview of Stanislav Lem's Solaris novel and the film Solaris directed by Andrei Tarkovsky. In "Cinema Technique" I talk about the specific rhythm of the scenes, the radical movement triggered by Tarkovsky in modern cinema, the role of symbolic and iconic elements, and affinities with the fantastic area of Russian literature. In Psychological Aspects I analyze the issue of communication in a human society of the future considered by Tarkovsky as rigid, the obsession of the house, and the personal evolution of Kris, Hari, and the relationships between them. In Philosophical Aspects, the film is analyzed through the philosophy of the mind (Cartesian dualism, reductionism and functionalism), the problem of personal identity, the theory of heterotopic spaces developed by Michel Foucault, and the semantic interpretations that can be deduced from the film. It also analyzes the issue of personal identity through Locke's philosophy. "Conclusions" show the general ideas of this essay, namely that Man's attempts to classify and maintain forms of interaction with unknown entities will always be condemned to failure and will reflect a major mistake in the panoptic world in which we live. In this framework of analysis of the philosophy of mind, functionalism seems to be the most intuitive. Solaris is, however, a movie that begins as a search for answers and comes to provide these answers with a whole range of different questions.

About the necessity and usefulness of developing a philosophy specific to the blockchain technology, emphasizing on the ontological aspects. After an Introduction that highlights the main philosophical directions for this emerging technology, in Blockchain Technology I explain the way the blockchain works, discussing ontological development directions of this technology in Designing and Modeling. The next section is dedicated to the main application of blockchain technology, Bitcoin, with the social implications of this cryptocurrency. There follows a section of Philosophy in which I identify the blockchain technology with the concept of heterotopia developed by Michel Foucault and I interpret it in the light of the notational technology developed by Nelson Goodman as a notational system. In the Ontology section, I present two developmental paths that I consider important: Narrative Ontology, based on the idea of order and structure of history transmitted through Paul Ricoeur's narrative history, and the Enterprise Ontology system based on concepts and models of an enterprise, specific to the semantic web, and which I consider to be the most well developed and which will probably become the formal ontological system, at least in terms of the economic and legal aspects of blockchain technology. In Conclusions I am talking about the future directions of developing the blockchain technology philosophy in general as an explanatory and robust theory from a phenomenologically consistent point of view, which allows testability and ontologies in particular, arguing for the need of a global adoption of an ontological system for develop cross-cutting solutions and to make this technology profitable.

BC. Information in society. - Abstract
About the analogy between the epistemological and methodological aspects of the activity of intelligence agencies and some scientific disciplines, advocating for a more scientific approach to the process of collecting and analyzing information within the intelligence cycle. I assert that the theoretical, ontological and epistemological aspects of the activity of many intelligence agencies are underestimated, leading to incomplete understanding of current phenomena and confusion in inter-institutional collaboration. After a brief Introduction, which includes a history of the evolution of the intelligence concept after World War II, Intelligence Activity defines the objectives and organization of intelligence agencies, the core model of these organizations (the intelligence cycle), and the relevant aspects of the intelligence gathering and intelligence analysis. In the Ontology section, I highlight the ontological aspects and the entities that threaten and are threatened. The Epistemology section includes aspects specific to intelligence activity, with the analysis of the traditional (Singer) model, and a possible epistemological approach through the concept of tacit knowledge developed by scientist Michael Polanyi. In the Methodology section there are various methodological theories with an emphasis on structural analytical techniques, and some analogies with science, archeology, business and medicine. In Conclusions I argue on the possibility of a more scientific approach to methods of intelligence gathering and analysis of intelligence agencies.

LH. Computer and network security. - Abstract
State features are affected by the connection with digital coins. Social systems create their own limits and remain alive according to their internal logic, which does not derive from the system environment. So, social systems are operationally and autonomously closed - interacting with their environment and there is a general increase in entropy, but individual systems work to maintain and preserve their internal order. Autopoietic systems (like the state, with the tendency to maintain the inner order with a remarkable degree of independence from the outside world) may contrast with allopoietic ones. It results in a state with a finite influence area, but recently troubled by the new forms of digital money and the corresponding infrastructure.

IZ. None of these, but in this section. - Abstract
In intelligence, the ontological problem is related to the nature and characteristics of entities that threaten and are threatened. Developing a threat ontology requires a taxonomy. An ontology for threat analysis and action must be able to shape ontological distinctions between potential and viable threats. This provides a better understanding of how threats (ie intentions, capabilities, and opportunities) can exist and can be changed over time. Escalating threats from a state of potency to a state of viability could be avoided by using appropriate threat mitigation techniques.

BC. Information in society. - Abstract
Epistemic communities are informal networks of knowledge-based experts who influence decision-makers in defining issues they face, identifying different solutions, and evaluating results. Epistemic communities have the greatest influence in conditions of political uncertainty and visibility, usually following a crisis or triggering event. Counterintelligence is primarily considered an analytical discipline, focusing on the study of intelligence services. The basis of all counterintelligence activities is the study of individual intelligence services, an analytical process to understand the behavior of foreign entities (formal mission, internal and external policy, history and myths within the entity, the people who compose it).

DI. Science libraries. - Abstract
Tarkovski’s film is a drama of pain and partial recovery centered on the psychology of the Solaris station crew. Tarkovski wanted to address this way the deeply emotional and intellectual science-fantastic genre, considered by him to be superficial. The film approaches a central phenomenon of Klaus Holzkamp’s critical-psychological analysis of human perception: the perceptions of the human world are significant to human beings. In perception, human beings are oriented towards an objective sense, which objects possess it in connection with the vital activity of the people. By virtue of this quality, the localization of meanings in objects is exclusively a characteristic of the human world.

BC. Information in society. - Abstract
The analysts are in the field of "knowledge". Intelligence refers to knowledge and the types of problems addressed are knowledge problems. So, we need a concept of work based on knowledge. We need a basic understanding of what we know and how we know, what we do not know, and even what can be known and what is not known. The analysis should provide a useful basis for conceptualizing intelligence functions, of which the most important are "estimation" and "prediction". The intelligence itself, in its basic form, has a decision-making function. Intelligence analysis applies individual and collective cognitive methods to assess data and test assumptions in a secret socio-cultural context.

A "free-market" approach to the genetic development of children may result in a homogenising. Parents may be inclined to choose according to models accepted by society. In this case, improving technologies "will grant racism and homophobia an unprecedented efficacy." One concern about the obligation to produce the best child in a particular society is that social norms may be discriminatory, so that in the end, for example, most children will be boys, extremists and heterosexuals. The sequencing of the human genome can help us in human evolution, to understand diseases for direct appropriate treatment, identify mutations that cause disease, and correct them.

HZ. None of these, but in this section. - Abstract
A process of intelligence gathering begins when a user enters a query into the system. Several objects can match the result of a query with different degrees of relevance. Most systems estimate a numeric value about how well each object matches the query and classifies objects according to this value. Many researches have focused on practices of intelligence gathering. In knowledge engineering, knowledge gathering consists in fiding it from structured and unstructured sources in a way that must represent knowledge in a way that facilitates inference.

CZ. None of these, but in this section. - Abstract
Tarkovsky opposed to the movie editing and considered that the basis of the art of cinematography (movie art) is the internal rhythm of images. He considers cinema as a representation of distinctive currents or time waves, transmitted in the film through its internal rhythm. Rhythm is at the heart of the "poetic film". A rhythm like a movement inside the frame ("sculpting in time"), not as a sequence of images in time. Time within the frame expresses something significant and true that goes beyond the events itself, received differently by each spectator. The rhythm is not determined by the length of the sequences, but by the pressure of time passing through them.
