SUMMARYIn the past years a large number of new surgical devices have been developed to improve the operation outcomes and reduce the patient's trauma. Nevertheless, the dexterity and accuracy required in positioning the surgical tools are often unreachable if the surgeons are not assisted by a suitable system. Since a medical robot works in an operating room, close to the patient and the medical staff, it has to satisfy much stricter requirements with respect to an industrial one. From a kinematic point of view, the robot must reach any target position in the patient's body, being as less invasive as possible for the surgeon's workspace. In order to meet such requirements, the right robot structure has to be chosen by means of the definition of suitable kinematic performance indices.In this paper some task-based indices based on the robot workspace and stiffness are presented and discussed. The indices will be used in a multiobjective optimization problem to evaluate best robot kinematic structure for a given neurosurgical task.

In this paper presents and analyzes the concept of the Agrarian Exchange from the point of view of scientists of the economic and legal community, as well as the legislative definition of the corresponding concept. Particular attention is paid to the study of legal documents designed to regulate the activities of the Agrarian Exchange, to establish its legal status. The issues of organizational and legal form and legal status of the property of the Agrarian Exchange are also revealed. Due to some similarities between the Agrarian and Commodity Exchanges, an analysis of the comparison of these two entities is given. The analysis allowed finding fundamental differences concerning the subjects authorized to create the Agrarian Exchange. At the same time, the paper proposes the need to create a subject of the agricultural market in such an organizational and legal form as a non-profit company. First of all, it will be correlated with the legal status of the property owned by the Agrarian Exchange. The possibility of participation in the founding activities of the Agrarian Exchange of large agricultural producers is also considered. But only if the Agrarian Exchange operates in a certain organizational and legal form, which may allow such participation alongside government agencies. That is why, the right of operative management of property, which has the Agrarian Exchange, is decisive for the legislator in the possible choice of organizational and legal form of creation of this entity. That is why the paper is aimed at encouraging the need to adopt a new legislative act that will clearly provide the nuances of the creation, operation and termination of the Agrarian Exchange.

Temporal concerns are baked into the matter of facts. From an etymological point of view, facts are moments of making and doing that are no longer alive and kicking. Coming into English and other modern Western languages by means of both the past participle of the Latin word facere (“to make or to do”) and the Latin noun factum, whose senses include the “result of doing” and “something done,” fact denotes an action that has happened and is now preserved like a fossil in the accumulated sediments of history (“Fact”). Etymologically speaking, facts are safely removed from the vicissitudes of the present and the whims of our leaders. So it makes sense that there should be some hand-wringing over facts that have become so thoroughly destabilized that they no longer seem to be based on anything. The defining moment in this distressing development occurred when the Trump administration, not content merely to put a spin on facts, dismissed quantifiable facts by summoning “alternative facts” to deny that the low attendance at the 2017 presidential inauguration was real. A dictionary, not the renowned one from Oxford but Urban Dictionary, offers the following definition of alternative facts: “an attempt to gaslight the population in an effort to control the media and create propaganda” (Mozzy-o). If only we could take refuge in etymology and remind ourselves and anyone else who will listen that facts are veritable faits accomplis, over and done with, past participles that stand as linguistic monuments to a bygone event beyond alteration.

Philosophy, in general, moves in a sphere of abstraction, and its statements claim to be necessary and of universal validity. The reader therefore expects them to appeal directly to his reason, and he does not normally reflect much on the time and historical conditions that determined what the philosopher took for granted. It is only in this age of historical consciousness that we have come to appreciate these factors more readily, and the great thinkers of the past appear to us more or less closely related to the culture of their age. The writings of Plato and Aristotle in particular are for us an inexhaustible source of information about Greek society and civilisation. This is true also in regard to the relation of Greek philosophy to the science of its time, and this is of special importance for our understanding. That relation can be traced throughout Aristotle's logical, physical, and metaphysical works; but the influence of other sciences and arts is no less evident in his ethics. In this paper I propose to examine the numerous references to medicine that occur in the Nicomachean Ethics. They are mostly concerned with the question of the best method of treating this subject. The problem of the right method is always of the utmost importance for Aristotle. The discussion of it begins on the first page of the Ethics, where he tries to give a definition of the subject of this course of lectures and attributes it to a philosophical discipline that he calls ‘politics’. He does so in agreement with the Platonic tradition. We can trace it back to one of the dialogues of Plato's first period, the Gorgias, in which the Platonic Socrates for the first time pronounces his postulate of a new kind of philosophy, the object of which ought to be the care of the human soul (φυχῆς θεραπεία). He assigns this supreme task to ‘political art’, even though it does not fulfil this function at present.

The article draws a parallel between P. Kulish’s and I. Franko’s disposition to the age-related ideological autorevision. It is argued that, experiencing evolution of the worldview and creative work, revising his own early radical social impulses caused by the ‘national radical stage’ (Franko’s definition) of liberation movement in Halychyna, mature Franko in 1896 – 1907 got closer to the views of P. Kulish, especially those of the late period of his life (1874 – 1897). Like the latter, Franko defended the right to worldview evolution and changing views. These typological coincidences consisted also in the movement from the center-left forces to the right-centered ones; the transition to the primacy of the national idea over the social one; the drastic national self-criticism and simultaneous emphasis on the nation-building and state-building; gradual reorientation from the idea of social revolutionary development of society to evolutionary progress and moderate “means and ways of acting and speaking” (as Franko called it); the warnings against admiring communist illusion, against ochlocracy; and, finally, in the focus on the leading role of the nationally conscious Ukrainian intellectuals in the liberation struggle. Ideological and formal parallels between Franko and Kulish were revealed not only in the letters and journalism, but also in Franko’s practice of grounding his works on the materials of the national, biblical and Christian history and mythology (i. e. literary historicism and mythologism, focused on the present, the future and the author’s personality; symbolic autobiography). From this point of view it is worth to compare:  “Pisnia Budushchyny” (“Song of Future”) – “Try Braty” (“Three Brothers”); “Pokhoron” (“Funeral”), “Ivan Vyshenskyi” – “Velyki Provody” (“Great Farewell Procession”), “Marusia Bohuslavka”, “Dramovana Trylohiia” (“Drama-like Trilogy”); “Moisei” (“Moses”) – “Mahomet i Khadyza” (“Muhammad and Hadiza”), “Duma-Perestoroha, Velmy na Potomni Chasy Potribna” (“Warning Refl ections that will be Needed in Future”); “Strashnyi Sud” (“The Last Judgement”) – “Kulish u Pekli” (“Kulish in Hell”); “Slavianska Oda” (“Slavic Ode”) – “Tsarski Slova” (“Royal Words”).

The Use of Drones in Combating International Terrorism from the Perspective of ‘ius ad bellum’Summary The increasing practice of using armed unmanned aerial vehicles (military UAVs, commonly known as drones) by some countries to eliminate suspected terrorists raises a number of controversies from the perspective of international law. These controversies are also related to the specific features of military UAVs, which make it possible to kill targeted individuals without risk to the military personnel of the country concerned, and thereby may encourage the abusive interpretation of the applicable legal regulations. This article discusses these issues from the perspective of ius ad bellum, in particular the right to self-defence. It shows the main controversial points on the scope of invoking the right to self-defence in such cases, in particular the possibility of invoking the right to self-defence in response to an attack by a non-state entity, the question of pre-emptive self-defence, the importance of the severity of the force used as a condition allowing for the use of force in self-defence, and the relevance of the principles of proportionality and necessity. The article also presents an outline of the vast and highly controversial issues associated with the definition of terrorism from the point of view of international law.

Entrepreneurship has become one of the vital activities for economic development. It is synonymous with job creation, innovation, improvement in the societal well-being and economic growth in developed and developing countries alike. There is great interest in entrepreneurship globally as well as in Malaysia. Over the past few years, many individuals, as well as families, are actively engaged with the small business. Also, in light of the 2013 GEM study, 12.7% of Americans are effectively occupied with beginning a business or are the proprietor/director of a business that is under three years of age. Simultaneously, the Halal industry, that represents the global Islamic economy, is the fastest-growing market in the world with $2.3 trillion market value. Halal entrepreneurs (Halalpreneurs) are the major contributors to this achievement as they constitute a significant portion of the total establishment in most of the Muslim countries. That is the reason Entrepreneurship has turned into a conventional term that depicts a wide range of practices that include being innovative, devilish and tricky. Entrepreneurship has been defined by many scholars, researchers, industry players, and academicians globally which have also been perceived in the same way by most of the economies around the world. However, the Islamic economy looks at the concept of ‘entrepreneurship’ in a different way and perceives it as ‘Halalpreneurship’. To define entrepreneurship in the halal industry, although, the term ‘Halalpreneurship’ is being used, surprisingly the term has not been defined properly yet. It is essential for the Muslim entrepreneurs to have a proper understanding of Halalpreneurship from Maqasid-al-Shariah perspective. Such point of view is crucial to justify the term in the Halal industry and differentiate from conventional entrepreneurs. On this context, this paper provides concept and definition of Halalpreneurship justifying from the perspective of Maqasid-al-Sharia’h. It also identifies the differences between Halalpreneurs and entrepreneurs using secondary resources available in the forms of literature, research papers, journal papers, articles, conference papers, online publications, etc. The findings of the study will clarify the concept of Halalpreneurship from Maqasid-al-Sharia’h perspective and recognize Halalpreneurs distinguished from conventional entrepreneurs.

The concept of “Armenian style” is chosen as the key word to perceive Komitas, a concept the deciphering and developing of which is supposed to be the main purpose of the scientist. The culturally invariant features of the nation are considered by “style” that define the proper kind of its identity. The movement of Armenian intellectuals, particularly that of Komitas for definition of “Armenian style” can be observed in the context of global developments of the borderline of the 19th and 20th centuries. In the history of mankind this period is characterized by the emergence of rapid means of communication and the activation of urban life, as a result of which the rural and traditional values began to crumble. The dangers of the abolition of those values were especially visible among such peoples as the Armenians, who being deprived of statehood fought for their existence within the borders of empires. From this point of view, the introduction of the idea of “Armenian style” by Komitas and his contemporaries was of historical necessity. Demonstrating that there is an independent “Armenian style” that has unique cultural expressions and unites the Armenian times and spaces, its spiritual and secular cultural spheres in a system, Armenian scholars and artists sought not only to justify the past of their nation, but also to legitimize its present, and most importantly, to create a vision for the future. In this article a view point is developed, according to which the very concept of “Armenian style” has been used first by the Armenian intellectuals in context of the newly restored landscapes of memory such as Ani, the excavations of which uncovered not only the ruins of the past Armenian statehood but also the hope of its recreation.

The ancient world is a paradigm for the memory scholar. Without an awareness that collective memories are not only different from individual memories (or even the sum thereof) but also highly constructed, ancient research will be fundamentally flawed. Many networks of memories are beautifully represented in the written and material remains of antiquity, and it is precisely the ways in which they are fashioned, distorted, preserved or erased through which we can learn about the historical process as such. Our evidence is deeply characterized by the fact that ancient ‘identity’ and ‘memory’ appear exceptionally strong. Responsible for this is a continuing desire to link the present to the remote past, which creates many contexts in which memories were constructed. The ancient historian therefore has the right tools with which to work: places and objects from the past, monuments and iconography, and textual narratives with a primary purpose to memorize and commemorate. This is paired with our desire to understand the ancient world through its own self-perception. With the opportunity of tapping into this world by way of oral history, personal testimonies are a desideratum in all respects. Memory of the past, however, is profoundly about ‘self-understanding’. This volume surveys and builds on the many insights we have gained from vibrant research in the field since Maurice Halbwachs’ and Jan Assmann’s seminal studies on the idea and definition of ‘cultural memory’. While focusing on specific themes all chapters address the concepts and expressions of memory, and their historical impact and utilization by groups and individuals at specific times and for specific reasons.

"Over the past years, a large number of statistical expressions used as a measure of accuracy, collectively referred to as error functions. These functions use to determine the best fitting data. Since accurate adsorption equilibrium information are necessary for the analysis and design of adsorption, error functions are used to valuation the validity of the adsorption mathematical models with experimental results by finding the most appropriate isotherm. Therefore, this overall review provides a definition of a number of common error function and explains the use of these functions in determine optimal adsorption data and chose the right isotherm.
