In the industrial halls it is often necessary to handle large objects, with a large and large table, which have to be transported not over long distances but moved from one place to another, raised, then lowered to various levels, left or right. Such repeated manipulations of heavy and dangerous objects can be done only with the help of a manipulator, which can be a crane, a specially designed trolley, a complicated robot or a simple manipulator as is the case for the one presented in the paper. The paper briefly presents the kinematic study of a manipulator with three mobilities, which can be used both in industrial halls and in garages, depending on its suitably chosen constructive size, which at smaller dimensions can be handled very easily. This manipulator can carry large loads, thus easing the work of the human being and preventing it from major dangers that can occur during the transport of large pieces and a large mass.

Starting from the cry of the seraphim in Isaiahʹ s prophecy, this article aims to follow the rhythm of the sacred harmony, transcending the symbols of the angelic world and of the divine names, to get to the face to face meeting between man and God, just as the seraphim, reflecting their existence, stand face to face. The finality of the sacred harmony is that, during the search for God inside the human being, He reveals Himself, which is the reason for the affirmation of “I Am that I Am.” Through its hypnotic cyclicality, the profane temporality has its own musicality. Its purpose is to incubate the unsuspected potencies of the beings “caught” in the material world. Due to the fact that it belongs to the aeonic time, the divine music will exceed in harmony the mechanical musicality of profane time, dilating and temporarily cancelling it. Isaiah is witness to such revelation offering access to the heavenly concert. He is witness to divine harmonies produced by two divine singers, whose musical history is presented in our article. The seraphim accompanied the chosen people after their exodus from Egypt. The cultic use of the trumpet is related to the characteristics and behaviour of the seraphim. The seraphic music does not belong to the Creator, but its lyrics speak about the presence of the Creator in two realities, a spiritual and a material one. Only the transcendence of the divine names that are sung/cried affirms a unique reality: God. The chant-cry is a divine invocation with a double aim. On the one hand, the angels and the people affirm God’s presence and call His name and, on the other, the Creator affirms His presence through the angels or in man, the one who is His image and His likeness. The divine music does not only create, it is also a means of communion, implementing the relation of man to God and, thus, God’s connection with man. It is a relation in which both filiation and paternity disappear inside the harmony of the mutual recognition produced by music, a reality much older than Adam’s language.

AbstractThe following work features elements to ponder and an in-depth explanation taken on the Anca Vasiliu’s study about the possibilities and ways of thinking of God by a rational entity, such as the human being. This is an ever relevant topic that, however, takes place in relation to Platonic authors and texts, especially in Late Antiquity. The common thread is that the human being is a God’s creature who resembles him and who is image of. Nevertheless, this also applies within the Christian Trinity according to which, not without problems, the Son is the image of the Father. Lastly, also the relationship of the Spirit with the Father and the Son, always within the Trinity, can be considered as a relationship of similarity, but again not without critical issues between the similarity of attributes, on the one hand, and the identity of nature, on the other.

Abstract Rosenzweig’s pathos with respect to an ultimate redemption raises the question of the desirability of a state in which so much has to be undone in order to retain nothing but the One, the All, the Eternal, and the True. Similar doubts arise concerning Rosenzweig’s portrayal of the ways that this state of redemption is anticipated in life: through prayer, love of neighbor, the communal hymn of the We. How accessible are these to “the human being” as such? Rather than arguing against what appears as a grand remnant of the urge for totality, I invoke here two figures whose concepts of redemption partly resemble Rosenzweig’s, but depart from him in ways that make all the difference: Benjamin and Kafka.

Abstract This paper addresses instantaneous motion characteristics of wheeled vehicles systems on even and uneven terrain. A thorough kinematic geometric approach which utilizes screw system theory is used to investigate vehicle-terrain combinations as spatial mechanisms that possess multiple closed kinematic chains. It is shown that if the vehicle-terrain combination satisfies certain geometric conditions, for instance when the vehicle operates on even terrain, the system becomes singular or non-Kutzbachian — it possesses finite range mobility that is different from the one obtained using Kutzbach criterion. An application of this geometric approach to the study of rate kinematics of various classes of wheeled vehicles is also included. This approach provides an integrated framework to study the kinematic effects of varying the vehicle and/or terrain geometric parameters from their nominal values. In addition, design enhancements of existing vehicles are suggested using this approach. This kinematic study is closely related to the force distribution characteristics of wheeled vehicles which is the subject of the companion paper [SN96].

There is no convincing evidence to support the view that antisocial behaviour can be accounted for by reference to concepts such as learning defect, immaturity or lack of moral fibre. The criminal displays behaviour towards authorities identical to that displayed by a patriot in an occupied country towards the enemy. This identical behaviour, it is asserted by some, shows in the one case instability, cowardice, lack of resolve and in the other case, stability, courage, resolve and strength of will. These statements reveal the attitudes and bias of the observer without illuminating the situation of the observed. It is more relevant to examine what the psychopath has learned and the conditions in which his learning took place than to pursue enquiries aimed at demonstrating a learning defect. The human being is born without the attitudes, beliefs and sentiments towards e.g. property, sexual object etc., which are necessary for his successful incorporation into his ongoing social group. It is the intention of society's socializing agents, the family and the school, to inculcate in the developing human being these necessary attitudes, sentiments and beliefs. Psychopathic personalities are the consequence of the socializing process gone wrong. This paper describes the types of psychopath together with the learning situations which brought them about. The implications for treatment programs are examined.

Nowadays more often people are asking about the meaning of life. It is a fundamental question that every human being faces. Man is asking whether life is worth living, what to do to make our life meaningful?A human being, among many needs, has the need for discovering the sense of life, the need comes from the very core of human existence as placed in time and connected with the phenomenon of passing away. Discovering the sense of life leads to the experience of happiness, joy, and to inner life lived much more to the full. Showing the meaning of life and helping to find that meaning are very important functions of religion. Due to it, a man is able to live one’s life, ambitions, goals, joyful moments as well as his or her suffering in the light of deeper understanding. Religion is the one that can often bring the richest and deepest answers to the question of the two meanings: the meaning of life and the world.

Existence and nonexistence of death in the semantic picture of reality and artistic text on the material of romans Leonid Leonov Road to the Ocean and Maxim Gorkogo The Life of Klim SamginIn this article the problem of death is unfolding in the semantic space of its ontological and existential conception in reality and a literary text. On the one hand, death as the concept of being is presented as its continuation, spiritual content, confirmation. On the other hand, death as a concept of non-being is considered as nothingness, rejection of being and its spiritual content.In reality the concept of death becomes an issue of the questionary and transcendental philosophy, that takes place in the physical time and metaphysical space of thought and expression. When the matter concerns the death of human being, his death acquires an ontological status of being, a status of spiritual significance. In the contrary case, it is possible to consider death and even life in terms of the concepts of being and nothingness. In literary texts the concept of death is also considered to be being or non-being, but taking into account constitutive characteristics of the text, its figurative and notional polysemant, the concept of death acquires not only aesthetic but also conceptual focus. In the article the main points of the topic of death, its being and non-being, are illustrated on the examples of specific literary texts. Буття і небуття смерті в смисловій картині реальності і художньому текстіПроблема смерті у статті розгортається в смисловому просторі онтологічного і екзистенціалістського її розуміння в реальності і в художньому тексті. З одного боку, смерть — поняття буття — постає як його продовження, його духовна наповненість, його стверждення. З другого — смерть — поняття небуття — розглядається як ніщо, як заперечення буття і його духовної наповненості.У реальності поняття смерті стає проблемою запитальної, трансцендентальної філософії, що розгортається у фізичному часі і метафізичному просторі думки і слова. І якщо йдеться про смерть буттюючої особистості, то і її смерть набуває онтологічного статусу, статусу духовної значущості, інакше можна говорити про смерть і навіть життя у поняттях небуття і ніщо. У художніх текстах поняття смерті також розглядається як буття і небуття, проте з урахуванням конститутивних особливостей тексту, його образної і смислової багатозначності, образ смерті набуває, крім онтологічної, ще й естетичну спрямованість.

Artificial intelligence has countless advantages in our lives. On the one hand, computer’s capacity to store and connect data is far superior to human capacity. On the other hand, its “intelligence” also involves deep ethical problems that the law must respond to. I say “intelligence” because nowadays machines are not intelligent. Machines only use the data that a human being has previously offered as true. The truth is relative and the data will have the same biases and prejudices as the human who programs the machine. In other words, machines will be racist, sexist and classist if their programmers are. Furthermore, we are facing a new problem: the difficulty to understand the algorithm of those who apply the law.This situation forces us to rethink the criminal process, including artificial intelligence and spinning very thinly indicating how, when, why and under what assumptions we can make use of artificial intelligence and, above all, who is going to program it. At the end of the day, as Silvia Barona indicates, perhaps the question should be: who is going to control global legal thinking?

Summary: Reflecting on the role humans take into nowadays society, should be of interest in all our social reflections, even for those that refer to the field of law. Any human indifferent and unconscious of the social role that he ought to play within society, as a member of it, is an irresponsible human detached from everything that surrounds him, regarding matters and other humans. Trying to isolate in an irresponsible, passive and comfortable attitude, means, after all, denying oneself, denying our nature, as the social being every human is. This is the reflection that this academic work entitles, the one made from the point of view of the Italian philosopher Rodolfo Mondolfo. From a descriptive development, starting from this renowned author, I will develop ideas that will warn the importance that human protagonism have, in this human product so call society. From a descriptive development, from this well-known author, I will be prescribing ideas that will warn the importance of the protagonism that all human beings have, in that human product that we call society. I have used the descriptive method to approach the positions of the Italian humanist philosopher and, for my assessments, I have used the prescriptive method from an eminently critical and deductive procedural position. My goal is to demonstrate, from the humanist postulates of Rodolfo Mondolfo, the hypothesis about the leading, decision-making and determining role that the human being has within society. I understand, to have reached the demonstration of the aforementioned hypothesis, because, after the analyzed, there is no doubt, that the human being is not one more existence in the development of societies; its role is decisive in determining the human present and the future that will house the next societies and generations of our historical future.
