Moving platforms were introduced in the field of the study of posturography since the 1970s. Commercial platforms have some limits: a limited number of degrees of freedom, pre-configured protocols, and, usually, they are expensive. In order to overcome these limits, we developed a robotic platform: Dynamic Oriented Rehabilitative Integrated System (DORIS). We aimed at realizing a versatile solution that can be applied both for research purposes but also for personalizing the training of equilibrium and gait. We reached these goals by means of a Stewart platform that was realized with linear actuators and a supporting plate. Each actuator is provided by an ad hoc built monoaxial load cell. Position control allows a large range of movements and load cells measure the reactive force applied by the subject. Transmission Control Protocol/Internet Protocol (TCP/IP) guarantees the communication between the platform and other systems. We integrated DORIS with a motion analysis system, an electromyography (EMG) system, and a virtual reality environment (VR). This integration and the custom design of the platform offer the opportunity to manipulate the available information of the subject under analysis, which uses visual, vestibular, and plantar feet pressure inputs. The full access to the human movements and to the dynamic interaction is a further benefit for the identification of innovative solutions for research and physical rehabilitation purposes in a field that is widely investigated but still open.

Proper assessment of reach posture is one of the essential functions for ergonomic workspace evaluation in CAD systems with a built-in man-model. In this study, Each upper limb is modelled as a four-link system, consisting of trunk, upper arm, lower arm, and hand, being regarded as a redundant manipulator with a total of eight degrees of freedom. Inverse kinematics is introduced in this study to predict the trajectory of multi-link segmental movement. Among several kinematic methods for solving the multi-link system, the resolved motion method was found to be effective to solve this redundant manipulator model, and the joint range availability was used as a performance function in order to guarantee local optimality. Real reach postures taken from the subject were analyzed by Motion Analysis System and showed reasonable results when compared to those obtained from the model.

Migration is one of the oldest and most used strategies for overcoming negative social issues. Despite the fact that it is historically deeply rooted, environmental migration as a social phenomenon has only recently become the subject research of numerous scientific fields. However, the study of current environmental migration is characterized by a number of issues, such as absence of an adequate definition and multi-causality of environmental migration. In this paper, through conceptual framework, author analyzed two main questions: who are environmental migrants and what reasons cause environmental migration. Due to the destruction of the global environmental balance, as well as accumulated environmental disturbances, it is likely that environmental migration will increase in future and there is nowhere you cannot make more use of scientific and professional projection of the future than in demographic and environmental spheres of human life. There is no doubt that our future is unpredictable. However, the environmental factors influencing the pattern of human interaction with the environment must be taken into account when projecting future development of the modern society. Such is the context in which the complex relation among migration, change and the environment has to be studied. In order to establish the basis for controlling environmental migration caused by negative changes in the environment, it is necessary to adopt a consistent strategy instead of ad hoc activities that are being used. In this paper, author analyzed societal response for the challenges caused by environmental migration, specifically regarding actions related to governing environmental migrations.

AbstractThe computational view of mind rests on certain intuitions regarding the fundamental similarity between computation and cognition. We examine some of these intuitions and suggest that they derive from the fact that computers and human organisms are both physical systems whose behavior is correctly described as being governed by rules acting on symbolic representations. Some of the implications of this view are discussed. It is suggested that a fundamental hypothesis of this approach (the “proprietary vocabulary hypothesis”) is that there is a natural domain of human functioning (roughly what we intuitively associate with perceiving, reasoning, and acting) that can be addressed exclusively in terms of a formal symbolic or algorithmic vocabulary or level of analysis.Much of the paper elaborates various conditions that need to be met if a literal view of mental activity as computation is to serve as the basis for explanatory theories. The coherence of such a view depends on there being a principled distinction between functions whose explanation requires that we posit internal representations and those that we can appropriately describe as merely instantiating causal physical or biological laws. In this paper the distinction is empirically grounded in a methodological criterion called the “cognitive impenetrability condition.” Functions are said to be cognitively impenetrable if they cannot be influenced by such purely cognitive factors as goals, beliefs, inferences, tacit knowledge, and so on. Such a criterion makes it possible to empirically separate the fixed capacities of mind (called its “functional architecture”) from the particular representations and algorithms used on specific occasions. In order for computational theories to avoid being ad hoc, they must deal effectively with the “degrees of freedom” problem by constraining the extent to which they can be arbitrarily adjusted post hoc to fit some particular set of observations. This in turn requires that the fixed architectural function and the algorithms be independently validated. It is argued that the architectural assumptions implicit in many contemporary models run afoul of the cognitive impenetrability condition, since the required fixed functions are demonstrably sensitive to tacit knowledge and goals. The paper concludes with some tactical suggestions for the development of computational cognitive theories.

International arrangements for the uses of the ocean have been the subject of long debate within the United Nations since a speech made by Ambassador Arvid Pardo of Malta before the General Assembly in 1967. Issues in question include the method of delimiting the outer edge of the legal continental shelf; the spectrum of ocean arms control possibilities; proposals to create a declaration of principles governing the exploration for, and the exploitation of, seabed mineral resources with the promise that exploitation take place only if it “benefits mankind as a whole,” especially the developing states; and consideration of schemes to create international machinery to regulate, license, or own the resources of the seabed and subsoil. The discussions and debates began in the First (Political and Security) Committee of the 22nd General Assembly and proceeded through an ad hoc committee to the 23rd and 24th assembly plenary sessions. The creation of a permanent committee on the seabed as a part of the General Assembly's machinery attests to the importance members of the United Nations attribute to ocean problems. Having established the committee, they will be faced soon with the necessity of reaching decisions. The 24th General Assembly, for example, passed a resolution requesting the Secretary-General to ascertain members' attitudes on the convening of a new international conference to deal with a wide range of law of the sea problems.

Received 30 January 2021. Accepted for publication 20 March 2021 The Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction (BTWC) does not have a legally binding verification regime. An attempt by the Ad Hoc Group of Experts, created by the UN Committee on Disarmament, to strengthen the BTWC by developing a legally binding document – the Protocol, was blocked by the United States in July 2001. The purpose of this work is to study the history, main provisions, significance and reasons for not signing the Protocol to the BTWC. The attention is paid to the events in biological weapons control, which have led a number of countries to the understanding of the necessity to develop the Protocol. The background of the US actions to block this document is the subject of special consideration. During the Second Review Conference on the Implementation of the Convention (8–25 September 1986, Geneva) the USSR, the German Democratic Republic and the Hungarian People's Republic proposed to develop and adopt the Protocol as an addition to the BTWC. This document was supposed to establish general provisions, definitions of terms, lists of agents and toxins, lists of equipment that was present or used at production facilities, threshold quantities of biological agents designed to assess means and methods of protection. The proposed verification mechanism was based on three «pillars»: initial declarations with the basic information about the capabilities of each State Party; inspections to assess the reliability of the declarations; investigations to verify and confirm or not confirm the alleged non-compliance with the Convention. The verification regime was to be under the control of an international organization – the Organization for the Prohibition of Bacteriological (Biological) and Toxin Weapons. However, the US military and pharmaceutical companies opposed the idea of international inspections. The then US Undersecretary of State for Arms Control and International Security, John Robert Bolton II, played a special role in blocking the Protocol. During the Fifth Review Conference in December 2001, he demanded the termination of the Ad Hoc Group of Experts mandate for negotiations under the pretext that any international agreement would constrain US actions. The current situation with biological weapons control should not be left to chance. Measures to strengthen the BTWC should be developed, taking into account the new fundamental changes in dual-use biotechnology. It should be borne in mind, that the Protocol, developed in the 1990s, is outdated nowadays.

Abstract In an effort to limit the effects of the COVID-19 epidemic determined by restrictions in economic activity and various areas of social activity, the catalogue of preventive actions was expanded by tax and legal instruments in the form of income tax reliefs inclining taxpayers to certain behaviours. The reliefs entitle taxpayers to deduct the value of donations made for the purposes of counteracting COVID-19 from the tax base. Two types of such donations have been distinguished, i.e., donations for entities participating in the treatment of infected persons and donations for educational institutions providing remote education. The aim of this article is to establish the premises justifying the claim that the tax reliefs for donations made by income tax payers are autonomous in relation to other tax preferences available to taxpayers making donations for other socially useful purposes. The hypothesis about the ad hoc and temporary nature of these tax reliefs has been verified as true, and the dominance of the motivating and stimulating function over their fiscal function has been demonstrated. Symmetrical solutions have been identified in the legal structure of the subject tax reliefs, as the donor uses a deduction from the tax base, while the recipient does not include the accepted donation in their income. The study uses the legal-dogmatic method and, in addition, the empirical analytical method to present the jurisprudence of courts in the field of applying tax reliefs due to donations made by income tax payers.

The problem that we need to be solved in the world of our education is the weak learning process. The learning process in the classroom is still directed at the child's ability to memorize information. While biology requires logical and reasonable learning to be accepted and absorbed by the brain so that it can last long. The aim of the research is to know the influence of course review horay learning toward student’s of cognitive learning class ten in the subject matter cell in MA Sabilul Hasanah Kecamatan Sembawa Kabupaten Banyuasin. This research method used quasi-experimental design with a quantitative approach research pretest-posttest control group design. The sample is taken by using purposive sampling techniques. The sample was grade XI MIA 2 as an experimental class and class XI MIA 1 as the control class. The instrument used in this research is a test to measure student’s cognitive learning about the cognitive categories C1-C4. Data analysis use the t-test, data on the calculation difference average posttest both groups earned value t-test much as 4,806 while value t-table with significant level5% with degrees of freedom (dk) 42 is equal to1,684, it can be said that t-test > t-table means the alternative hypothesis (Ha) be accepted and the null hypothesis (H0) rejected. It can be concluded that there is a significant influence of course review horay learning toward student’s of cognitive learning class eleven in the subject matter cell inMA Sabilul Hasanah.

The purpose of the article is to explore the types of personnel procedures in the National Police of Ukraine on the basis of scientific developments of scholars and to carry out their classification. To achieve this goal, such methods as formal-logical, comparative analysis, system-structural and comparative-legal was used. The successful functioning the National Police of Ukraine is not possible without the proper selection of highly qualified employees, which can be ensured through the introduction of truly effective and efficient personnel procedures. The theoretical and legal approaches to the division of personnel procedures into appropriate types by different classification criteria are analyzed and summarized, in particular, depending on: a) the subject of the initiative; b) the nature of the consequences; c) the type (direction) of the activity of the authority. The personnel procedures, which are divided into ordinary and simplified, are also illustrated. The tasks of the National Police Personnel Department are given. It is stated that the achievement of effective work of the National Police bodies is not possible without further improvement of the mechanism of personnel procedures, since insufficient work with staff has a negative impact on the reform of this law enforcement agency. As a result of the study the author's classification of personnel procedures in the National Police of Ukraine was proposed, namely, according to the following criteria: 1) by the subject of the initiative of the personnel procedure; 2) by the nature of the consequences for the subject of the personnel relations; 3) by the stage of staffing; 4) by the direction of activity of the subject of personnel relations in the police force; 5) by the degree of regulation; 6) by functional purpose; 7) by tasks of staffing.
