The use of brainwave signal is a step in the introduction of the individual identity using biometric technology based on characteristics of the body. Brainwave signal has unique characteristics and different on each individual because the brainwave cannot be read or copied by people so it is not possible to have a similarity of one person with another person. To be able to process the identification of individual characteristics, which obtained from the signal brainwave, required a pattern of brain activity that is prominent and constant. Cognitive activity testing using a single-sensor EEG (Electroencephalogram) divided into two categories, called the activity of cognitive involving the ability of the right brain (creativity, imagination, holistic thinking, intuition, arts, rhythms, nonverbal, feelings, visualization, tune of songs, daydreaming) and the left brain (logic, analysis, sequences, linear, mathematics, language, facts, think in words, word of songs, computation) give a different cluster based on two times the test on mathematical activities (no cluster slices of experiment 1 and experiment 2). The result showed that cognitive activity based on math activity can provide a signal characteristic that can be used as the basis for a brain-computer interface applications development by utilizing EEG single-sensor.

The current world situation is both frightening and alarming due to the massive disruption caused by the Covid-19 pandemic. The next few days are censorious as we need to be very precautious in our daily regimen as well as dietary habits. Ayurveda offers knowledge about food based on certain reasoning. Indecent food custom is the chief cause for the rising development of health disorders in the current era. In classical texts of Ayurveda, the concept of diet explained well, ranging from their natural sources, properties and specific utility in pathological as well as physiological manner. In this work, the review of the relevant literature of Ahara (Diet) was carried out from Charak Samhita and other texts, newspapers, articles, web page related to the same.  Every human being is unique with respect to his Prakriti (Physical and mental temperament), Agni (Digestive capacity), Koshtha  (Nature of bowel) etc. For that reason, the specificity of the individual should be kept in mind. Ahara, when consumed in the appropriate amount at the right moment following all Niyamas (Guidelines) given in Ayurveda texts, gives immunity and keeps the body in a healthy state during pandemics such as Covid-19. Ultimately, this will help the human body to maintain its strength for life. This article reviews the concept of diet viz. combination of foods, their quantity and quality, methods of preparation and processing, which are to be followed during pandemics and are essential in maintenance and endorsement of health and preclusion of diseases.

AbstractEndometriosis is a common condition that affects reproductive-aged women and is characterized by the presence of endo-metrial tissue outside the uterine cavity with nodules and lesions. The study aimed to analyze lifestyles of women affected by endometriosis in relation with their symptoms. In this observational study, 735 Italian women have been interviewed online through a questionnaire structured in two parts. The first part was mainly anamnestic, focused on gathering information about the age, the stage of disease, comorbidities, involved organs, symptomatology, chirurgical treatment, induced menopause. The second part focused on the individual characteristics and lifestyle of the patients such as the body mass index, physical activity, quality of sleep, and the diet. The results showed how a healthy diet and a regular physical activity reduce drastically the symptoms of the patients.

The article is devoted to the problem of formation of creative abilities and cognitive interests of students. The main directions of development of the creative person according to the social needs of the present are considered. It is noted that creative activity becomes a form of knowledge of the material-objective world; identifies personality possibilities, new ways of one’s personal development. Therefore, the problem of developing the creative abilities of students in the course of educational and cognitive activity is of an exceptional relevance. The author believes that influencing the organization of creative activity is possible only under certain conditions, in particular: to conduct classes in an atmosphere of mutual understanding and co-creation, perceiving each student as a person; to give preference to the dialogical form of conducting classes, when students have an opportunity: to think independently, to make suggestions, to defend their own point of view, presenting their own arguments; it is advisable to create situations of choice at classes and to enable students to carry it out. The author notes that the observance of certain organizational and methodological conditions can significantly contribute to the development of creative potential of students, namely: the creative vision of the world through the systematic organization of work with students; development of creative values through the proper level of teacher's teaching skills; deepening the perception of the world picture through the integration of various types of students’ creativity, works of art and their figurative reproduction in their own creative activity; individual peculiarities of perception and emotional attitude through the use of the educational potential of the family, organization of creative activity. When performing creative tasks the individual characteristics of students to select the material of the appropriate level of complexity must be taken into account. The article examines the examples of students' creativity during the European Cultures Festival, debates and clubs on the basis of the Kryvyi Rih National University.

With the exception of Figs. 1, 2, 3, the Gold Ornaments engraved in Plate VIII. have no reference whatever to each other. The first three were obtained by Viscount Strangford, Director of the Society, from a Greek priest at Milo, in the year 1820. Figs. 1 and 3 appear to have formed the ends of a light chain, and the other (fig. 2) to have been pendent by a small loop on the top of the head. The figure has unfortunately lost the feet and the left hand, but the other parts are perfect. The right hand is raised in an admonitory attitude. The forehead appears as if encircled with a wreath, while the body is crossed by what would seem to be intended for the tendril of a vine. The necklace was formerly in the collection of the late Mr. H. P. Borrell, of Smyrna, but I am informed by his brother, Mr. Maximilian Borrell, who now possesses it, that no record exists of its discovery, and that he cannot learn the name of the individual from whom it was purchased. It was well known that Mr. H. P. Borrell was in the habit of purchasing ancient coins, which were sent to him from all parts of Greece and Asia-Minor, and that many rare and unique specimens fell into his hands, of which he contributed descriptions in various volumes of the Numismatic Chronicle. The necklace may, therefore, have been included in one of these numerous consignments, and we can scarcely indulge the hope that the place of its discovery will ever be made known. As an example of ancient art, it may vie with the most elaborate and beautiful specimens of goldsmiths' work of any age or period. The details are wonderfully minute and delicate, even the backs of the button-like objects at the ends of the pendent cords being elaborately finished.

Under appropriate conditions, an observer's memory for the final position of an abruptly halted moving object is distorted in the direction of the represented motion. This phenomenon is called “representational momentum” (RM). We examined the effect of mental imagery instructions on the modulation of spatial orientation processing by testing for RM under conditions of picture versus body rotation perception and imagination. Behavioral data were gathered via classical reaction time and error measurements, whereas brain activity was recorded with the help of magnetoence-phalography (MEG). Due to the so-called inverse problem and to signal complexity, results were described at the signal level rather than with the source location modeling. Brain magnetic field strength and spatial distribution, as well as latency of P200m evoked fields were used as neurocognitive markers. A task was devised where a subject examined a rotating sea horizon as seen from a virtual boat in order to extrapolate either the picture motion or the body motion relative to the picture while the latter disappeared temporarily until a test-view was displayed as a final orientation candidate. Results suggest that perceptual interpretation and extrapolation of visual motion in the roll plane capitalize on the fronto-parietal cortical networks involving working memory processes. Extrapolation of the rotational dynamics of sea horizon revealed a RM effect simulating the role of gravity in rotational equilibrium. Modulation of the P200m component reflected spatial orientation processing and a non-voluntary detection of an incongruity between displayed and expected final orientations given the implied motion. Neuromagnetic properties of anticipatory (Contingent Magnetic Variation) and evoked (P200m) brain magnetic fields suggest, respectively, differential allocation of attentional resources by mental imagery instructions (picture vs. body tilt), and a communality of neural structures (in the right centro-parietal region) for the control of both RM and mental rotation processes. Finally, the RM of the body motion is less prone to forward shifts than that of picture motion evidencing an internalization of the implied mass of the virtual body of the observer.

AbstractAiming to deepen our understandings of corporeal and embodied dimensions of transnational feminist and LGBTI + activism, this chapter is driven by the question: Why does the body still remain an important instrument of queer and feminist struggles in the era of digital solidarities? Following the International Women’s Day in diverse locales in Sweden, Turkey, and Russia, the ethnographic analyzes in this chapter bring forth the significance of embodied forms of resistance for the (re)making of space and explore how resistance flows across various scales. Engaging with the ambiguities of embodied resistance, this chapter visualizes the potential of corporeal modes of resistance to shift from the individual to the collective, showing that attention to multiple scales of resistance can provide more fine-grained understandings of the possibilities and constraints within which feminist and LGBTI+ struggles are located.

Health news has a special position due to both their corporate significance and being for the special/private areas of the readers. They also directly influence the health right, which is one of the fundamental, irreplaceable, nontransferable rights of the individual and based on the “value of being human”. The health news which is made inattentively or false can lead to ending an individual’s life or reducing the life quality of an individual.In this regard, in this study, which aims to reveal the ethical principles of health journalism in Turkey within the framework of social responsibility theory in relation to health journalism which requires a privileged responsibility and attention, a qualitative approach was adopted where the data was collected through document analysis and interviews.As a result, the health journalist needs to observe personal rights and act responsibly in order to avoid disrupting the body unity of a person, adversely affect the life quality of a person and avoid preventing the right to access to equal and quality health services in his professional journalist behaviors while producing news. Within this framework, the Ethical Principles of Health Journalism which should be taken into consideration by the journalist in the production process of the health news are as follows: Principle of not harming, principles of honesty and objectivity, principles of privacy and private life, principle of equity.Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetSağlık haberleri hem taşıdıkları kamusal önem hem de okuyucuların özel/mahrem alanlarına yönelik olmaları nedeniyle özel bir konuma sahiptir. Aynı zamanda kaynağını insanın “insan olma değeri”nden alan ve bireyin temel, vazgeçilemez, devredilemez haklarından biri olan sağlık hakkını doğrudan etkilemektedir. Özensiz, eksik veya yanlış yapılan bir sağlık haberi, bireyin yaşamının sonlanmasına veya yaşam kalitesinin düşmesine neden olabilmektedir.Bu bağlamda ayrıcalıklı bir sorumluluk ve özen gerektiren sağlık haberciliği ile ilgili olarak, Türkiye’de sağlık haberciliği etik ilkelerinin ortaya konulması amaçlandığı çalışmada, verilerin doküman incelemesi ve görüşme yoluyla toplandığı nitel yaklaşım benimsenmiştir.Sonuç olarak sağlık habercisinin haber üretiminde profesyonel gazetecilik davranışlarının gereğiyle, kişinin vücut bütünlüğünü bozmamak, yaşam kalitesini olumsuz etkilememek, eşit ve kaliteli sağlık hizmetine ulaşma hakkını engellememek adına, kişilik haklarını da gözeterek, sorumlu davranmasının gerekliliği ortaya çıkmaktadır. Bu çerçevede gazetecinin sağlık haberi üretim sürecinde göz önünde bulundurması gereken Sağlık Haberciliği Etik İlkeleri; zarar vermeme ilkesi, doğruluk ve objektiflik ilkesi, mahremiyet ve özel hayat ilkesi, hakkaniyet ilkesi olarak belirlenmiştir.

The article emphasises the development of motives and needs of a medical student as one of the most relevant issues in motivation psychology for a future doctor. The importance of this problem is beyond a shadow of doubt, since the issue of the development of motives and needs is closely linked with the development of the individual on the whole. The motive can also be defined as the concept, which in a generalizing form says that there are many predilections. It activates the body, stimulates its behaviour and is aimed at determining what is needed. In the process of human activity, the personality develops and the environment in which the person lives is transformed. Needs are the driving force of personality development. Motives (predilections), needs and goals are components of the human’s motivational sphere. Considering the motivation of educational activity, it must be emphasized that the concept of motive is closely related to the concept of purpose and need. Motivational sphere includes: the need for learning, the importance of learning, the motive to learn, purpose, emotions, attitude and interest. The ability to create situations which promote the interest in the teacher as well as in learning. The more active are the teaching methods, the easier it is for the students to get interested. One of such methods at the Department of Therapeutic Dentistry is the realization of a programme of practical classes for highly motivated students, whose goal is to develop practical skills related to the future profession of the dentist during the course of preliminary training. Nowadays requires not only to improve methods in which the principle of mere repetition is basic and leads to intellectual and physical overload of students, but by means of finding new, more effective methods of educational and cognitive activity of students, to form their professional motivation. The article is devoted to the questions of motivation of the future doctor and the formation of his needs for constant self-improvement during practical classes and the individual work beyond the requirements of the programme.

The individual characteristics of the human visual apparatus are associated with the anatomical and psychophysiological parameters of his body. Based on the EyeTracking technology, the physiological aspects of the perception of visual information by the oculomotor apparatus, which are not associated with active cognitive activity, have been investigated. The individual features in the size of fixation when reading text and examining halftone graphic objects in various people have been investigated. The time durations of fixations in different people, associated with the process of accommodation, as well as the internal structure of fixations, were investigated. It is shown that the trajectory of the gaze shift in fixation has an internal heterogeneous structure. The total trajectory of eye movement in the fixation area is determined by a set of successive clusters. This fixation structure is apparently associated with the processes of restoration of the photosensitivity of rhodopsin in the photoreceptors of the retina. All the above studies of the fixations of various subjects on the basis of various images showed that the oculomotor system, taking into account the physiological characteristics of the visual apparatus, is equally controlled by the "video processor" of the brain when the eye is accommodated to the image elements. And the only objective individual feature of human vision, which uniquely characterizes the perception of graphic information, is the value of the average displacement in fixation. It is she who is the "visiting card" of the subject and remains practically unchanged both when reading and when examining halftone images and in test validation with forced fixation of the gaze.

The article examines the individual’s right to information privacy as an opportunity to have a non-public area of life. It is argued that a person, being a vulnerable creature, feels the need for secrecy, closeness and opacity of his or her personality. The right to information privacy does not mean complete concealment of private life, but the possibility of regulating access, when individuals can choose whom, when and to what extent to reveal the details of their lives. This presupposes both a person who feels him or herself to be an autonomous person and a society that respects his or her rights and freedoms. There is a duty of restraint and tact, which prohibits violating someone else’s privacy. As one of the aspects of privacy, in addition to the inviolability of the body and home, the human right to information protection is recognized. The theoretical foundation of the right to privacy is the philosophy of liberalism, which protects the individual from unwanted interference from the state and society. The need for private space has evolved in human history along with the growth of individualism. Currently, the right to information privacy is gaining special relevance in connection with the development of digital technologies that allow collecting, storing and processing large amounts of data. As a result, a person, on the one hand, does not know who, when and for what purpose collects his or her data, and, on the other hand, he or she often voluntarily, in connection with the need for social recognition, leaves information about him or herself on social networks. As a result of such actions, the loss of control over personal information can lead to undesirable consequences.
