he end of the twentieth century and the beginning of the twentyfirst century has begun the rapid development of scientific researches in the biological and medical fields. This process is associated with using of fundamentally new methods, which are primarily aimed at the disease prevention, as well as the introduction into the treatment of human diseases with the latest scientific and innovative technologies, methods and techniques of their application. These opportunities in the development of scientific technologies in the field of biology and medicine have led to the emergence of such a direction of scientific activity as "biotechnology". The proposed article notes that using of biomedical technologies has caused a number of new problems in the field of law and ethics. Legal arrangement in the field of the health protection have become much more complicated. Thanks to new opportunities, today these relations regulate rights and responsibilities of a fairly large number of people. Modern relations in the field of medical services and medical care lead to the emergence of new approaches to their regulation by both legal and ethical norms. In the past, relations in the field of the health protection were usually between two subjects, a doctor and a healthcare consumer. Nowadays, in a medical practice, relations in the field of the health protection involve: a health-care consumer, his family members (e.g., in the case of hereditary diseases diagnosis, blood and organ donation etc.) and third parties (e.g., organ donation, reproductive cell donation, surrogacy etc.). In the general doctrinal concept, biotechnology is the industrial use of living organisms or their parts (microorganisms, fungi, algae, plant and animal cells, cellular organs, enzymes etc.) for product producing or modifying, improving plants and animals, and in medical practice - in relation of the individual human organs (or body as a whole) functioning. These circumstances require improving the legal regulation of modern medicine public relations, bringing them into line with emerging realities. Moreover, the specifics of relations in this field determines the specifics of their legal regulation. The application of new medical technologiesin relation to human treatment has given rise to a significant number of moral and ethical problems that could not be solved within the framework of medical ethics and deontology alone. In connection with this, the way out of the current situation could be the consolidation of bioethics as an interdisciplinary field of knowledge, as a science, which makes it possible to explain moral, ethical and legal aspects of the medicine. This, for example, determines the allocation of medical law in an independent branch of law in some Western countries and Ukraine. The article focuses on biomedical ethics, which is a component of the medical activities system regulation. In the context of considering the levels of social regulation of medical activities, bioethics (biomedical ethics) is an interdisciplinary science that studies moral and ethical, social and legal problems of medical activities in the context of human rights protection. Bioethics should create a set of moral principles, norms and rules that are binding on all mankind and delineate the limits of scientific interference in the nature of the human body, the transition through which is unacceptable.

AbstractWith the rapid development of gymnastics technology, novel movements are also emerging. Due to the emergence of various complicated new movements, higher requirements are put forward for college gymnastics teaching. Therefore, it is necessary to combine the multimedia simulation technology to construct the human body rigid model and combine the image texture features to display the simulation image in texture form. In the study, GeBOD morphological database modeling was used to provide the data needed for the modeling of the whole-body human body of the joint and used for dynamics simulation. Simultaneously, in order to analyze and summarize the technical essentials of the innovative action, this experiment compared and analyzed the hem stage of the cross-headstand movement of the subject and the hem stage of the 180° movement. Research shows that the method proposed in this paper has certain practical effects.

<p>Organ transplantation and biotechnological research depend on the availability of body parts, which necessitates the willing involvement of the public. The rapid development of biotechnology has led to a search for an adequate decision-making framework for the acquisition, retention and utilisation of body parts. It has also lead to disquiet about the commercialisation of research with the source being the only participant who is unable to benefit financially. In developing such a framework it is necessary to conceptualise the nature of the interest that individuals have in their bodies. The principle of autonomy may form a basis for structuring decision-making and weighing conflicting principles. As a society we value autonomy in the sense that a competent adult may make decisions about his or her own health care. The concept is that of an individual separated from others by a wall of rights. This may be of assistance as a basis for formulating competing rights, but this must then be mediated with reference to other principles. In this context this thesis applies the concepts of property interests to the human body. The purpose of this research is to consider selected bioethical issues in an attempt to formulate a principled approach to issues of consent and control over the body and its component parts. It argues that a living person should have a property interest in excised body parts during life. There should also be a property interest in the cadaver that arises at the point of death, which can be passed to the deceased's personal representative, who would be required to deal with the cadaver in accord with the previous instructions of the deceased. However, it does not argue that there are property interests in entire living persons. It does not suggest that property alone is adequate to resolve the issues, but that it should operate alongside existing concepts such as autonomy, informed consent and privacy. It proposes draft legislation to illustrate the operation of the suggested medico-legal framework. It recognises that any framework should be respectful of Maori cultural values, in light of the special position of Maori as tangata whenua, as expressed in the Treaty of Waitangi. It argues that the framework allows Maori the freedom to choose collective or individualistic decision-making, in recognition of the diversity of values within the Maori population. In addition, it considers areas where public policy might determine that the free disposition of this property interest should be restricted to protect vulnerable persons, such as incompetent persons and living organ donors.</p>

This article is the fourth and last part of a series aimed at extending and correcting the anatomical nomenclature. Because of the rapid development of internet and the use of electronic formats in communication in anatomy, embryology, histology, medical education and clinical medicine, an appropriate, precise and concise anatomical nomenclature is required. Such tool enables to avoid any potential confusion and possible scientific/medical mistakes. The up-to-date official anatomical terminology, Terminologia Anatomica, is available longer than 20 years and needs to be refined and extended. The authors have collected and listed 210 terms and completed them with definitions and/or explanations. We aimed to start a discussion about their potential incorporation into the new revised version of the Terminologia Anatomica. This article is primarily focused on the vessels of the human body (arteries, veins and lymphatic system).

Lower limb exoskeletons are experiencing a rapid development that may suggest a prompt introduction to the market. These devices have an inherent close interaction with the human body; therefore, it is necessary to ensure user’s safety and comfort. The first exoskeletal designs used to represent the human joints as simple revolute joints. This approximation introduces an axial misalignment issue, which generates uncontrollable internal forces. A mathematical description of the said misalignments is provided to better understand the concept and its consequences. This review will only focus on mechanisms aiming to comply with its user.
