Сoronavirus created all over the world a fear of death. How this virus was originated? The standard explanation from the Chinese was that in the wet market of Wuhan as there are Bat meat and Pangolean meat, virus was originated there and gradually spread all over Wuhan and other areas of China and then all over the world. However, serious doubts are now raised in the non-Chinese world. The reason is Bat was not sold in the wet market of Wuhan. There are active research going on in the Institute of Virology in Wuhan on various deadly virus, under the control of the Chinese military. Questions are raised whether accidentally virus was released from that Institute or it was deliberate.

Background and Aims: The effect of operation volume on the outcomes of pancreatic surgery has been a subject of research since the 1990s. In several countries around the world, this has led to the centralization of pancreatic surgery. However, controversy persists as to the benefits of centralization and what the optimal operation volume for pancreatic surgery actually is. This review summarizes the data on the effect of centralization on mortality, complications, hospital facilities used, and costs regarding pancreatic surgery. Materials and Methods: A systematic librarian-assisted search was performed in PubMed covering the years from August 1999 to August 2019. All studies comparing results of open pancreatic resections from high- and low-volume centers were included. In total 44, published articles were analyzed. Results: Studies used a variety of different criteria for high-volume and low-volume centers, which hampers the evaluating of the effect of operation volume. However, mortality in high-volume centers is consistently reported to be lower than in low-volume centers. In addition, failure to rescue critically ill patients is more common in low-volume centers. Cost-effectiveness has also been evaluated in the literature. Length of hospital stay in particular has been reported to be shorter in high-volume centers than in low-volume centers. Conclusion: The effect of centralization on the outcomes of pancreatic surgery has been under active research and the beneficial effect of it is associated especially with better short-term prognosis after surgery.

Since the summer of 1995, Chinese military training opposite Taiwan has received unusual prominence in both the Chinese and foreign media. The senior leadership in Beijing was able to flex its military muscle because of a training programme begun years ago. This limited use of force has sent unmistakable political signals to Taiwan and the world. But, should the Chinese leadership decide to employ the People′s Liberation Army (PLA) in pursuit of its political objectives, is it well trained enough to conduct successful modern military operations?

This book studies situations in which individuals threaten each other or feel threatened by society, and often respond in ways that threaten social stability in turn. Animals also engage in all sorts of threats, an understanding of which opens one's eyes to the world of animal behavior otherwise hidden, while also revealing the strange and important question of honest versus dishonest communication. The dynamic of threat-and-response gives insight into such human dilemmas as the fear of death and how this has been manipulated by many organized religions; how fear of strangers and supposed enemies has given rise to an American gun culture that in turn threatens those seeking to avoid such threats; how nativist fears of “the other” has promoted right-wing nationalist populism, which has been making things worse not only for democracy itself, but also for those who feel threatened in the first place; and how capital punishment—intended to contain the threat of murderous criminals—has made this problem worse. Most important and worrisome is how countries convey the ultimate threat against each other: deterrence. Brandishing the threat of mutual annihilation in the expectation that this will keep a country safe is, paradoxically, the ultimate example of a posture that endangers threatener and threatened alike.

The article is devoted to the study of the activities of one of the institutions of children’s socialization – a self-regulated children's group. The self-regulated children's group is a voluntary gathering of children living in the same neighborhood. Until recently, such a group played a significant role in nurturing in a person such qualities that are required in society: the ability to negotiate with others, the ability to defend one's opinion in permitted manner, the ability to act in accordance with the rules accepted in society, the ability to work for the benefit of others, etc.The aim of the study was to determine the presence of the group as a socialization institution, the features of the group's emergence in a historical context, the characteristics of Latvian children's groups, their structure, territory, dwellings, activities.Child’s participation in a self-regulated children's group is a necessary stage of socialization in a traditional society.The study, based on which one can explain the existence of a self-regulated children's group, was made by M.V. Osorina. She examined the concept of the world in the consciousness of an individual and the formation of this concept at various stages of the child's development. The formation of the image of the world occurs due to the mastery of space: his own body, family home, the place where the child lives. The child's territorial space increases as he grows up. He inhabits each of these places, and goes from social-daily to deeply-significant knowledge. When the child's territory expands and goes beyond the boundaries of his yard, he lives in it with other children. In author’s opinion, when they gather in groups, children begin visiting places that until then were forbidden. According to M.V. Osorina, this territory includes the "boundaries", "ways" along which every child loves to walk, and a "place" – the locus of space where a person satisfies any needs and experiences certain feelings. Such places are places for games, "scary" places, places of existential-philosophical and religious experiences, "interesting" places, places of meetings, places of solitude. A unique material was collected by the author about the "headquarters" that the children built in their territory.The group facilitates the formation of a group identity through the development of the idea of "Us" in joint walks, games, pranks, etc. Belonging to the group is strengthened by the use of secret "languages", incomprehensible to the uninitiated.An old study of R. Hurt (1978) reveals the features of territorial behavior of children in a small American town. He found that from 7 to 14 years of age, the boundaries of space that children live in expand rapidly. According to the author, this is due to the entry of children into school. Boys always take up a space 1,5-2 times larger than girls. At the age of 14, children no longer tend to explore new spaces, but live within known limits.Looking ahead, we would like to note that according to our data, at this age most children are already leaving the self-organized children's group. Consequently, the territory expands as long as the group needs it, and the active research behavior is more in the interest of the group than of each individual child.

Sentiment Analysis (SA) is an active research area for the last ten years. SA is the computational treatment of opinions, sentiments, and subjectivity of text. Twitter is one of the most widely used micro-blog and considered as an important source for computation of sentiment and of data analysis. Therefore, companies all over the world analyze Twitter data using SA and extract knowledge which has potential applications in diverse areas. Although SA is the successful way of finding the people’s opinion, the bias in the tweets affects the results of the SA and reflects inaccurate analysis that may mislead users to take erroneous decisions. The biased tweets are shared by valid, but biased human users as well as the social bots to propagate the biased opinions on certain topics. To counter this, this research study proposes a statistical model to identify such users and social bots who share the biased content in the form of tweets in the Twitter social media. For experiment purpose, we use annotated twitter dataset and argue the results of SA with and without the biased tweets and explored the effects of biased users at micro-level and macro level. The empirical results show that the proposed approach is effective and properly identifies the biased users and bots from other authentic users using sentiment analysis.

Schopenhauer is portrayed as the philosopher of pessimism, and for good reason. For him, life is suffering where ‘ultimately death must triumph’ (The World as Will and Representation vol. I, 311). However, his pessimism fades away when he contemplates death. He argues enthusiastically that, far from being an evil, death is in fact a friend we should welcome. Moreover, he believes it is possible for human beings to use their knowledge to fight the fear of death. Interestingly, however, at the point where the reader expects a philosophical defense of suicide, Schopenhauer vehemently argues against it. Suicide to avoid pain and suffering, according to him, is a mistake, a futile, foolish and egoistic act. Not only does suicide not offer a genuine solution to suffering, but also it hinders true salvation, the denial of the will.In this paper, I argue that Schopenhauer’s condemnation of suicide is in fact at odds with his views on death and can weaken his argumentation about why we must not fear death. It is my belief that Schopenhauer’s views on suicide stem - quite ironically - from his being, at times, overly optimistic about the possibility of genuine salvation. When it comes to freeing ourselves from the will, however, we are better off pessimists. This, I explain, will allow us to at least keep our optimism regarding death and find solace in the knowledge that - be it by old age, illness, accident, suicide or any other cause - death is not to be feared.

Currently, the most deadly diseases in the world medical practice are cardiovascular diseases (CVD). The causes of CVD are incorrect lifestyle, which is currently often observed in our society. People do not exercise enough, eat fatty foods, fast food, experience stress, smoke (including drugs), and abuse alcohol. Active research is underway to find new drugs, but most of them are chemical drugs that usually have adverse events. The solution to the problem can be the use of medicines based on official medicinal plant material (MPM). It is worth noting the feasibility of using MPM and phytotherapy in the treatment of human diseases. The popularity of herbal medicine is due to the naturalness of phytopreparations, their low degree of allergenicity and toxicity, and easy assimilation by the human body of substances of plant origin.

Death motifs in egodocuments by Ivan BuninDeath is one of the most crucial subjects not only in Bunin’s literary works but also in his egodocuments. The writer’s perspective on the world was mainly concentrated around death, illness, passing, loneliness and old age.Through such a prism he perceived himself, his loved ones and the surrounding world, what was reflected in the writer’s diaries and letters. In spite of Bunin’s fear of death, in his considerations on fate he put fatalistic and affirmative motifs together.Мотив смерти в эго-документах Ивана БунинаСмерть является одной из важнейших тем не только в творчестве Ивана Бунина, но также в его эго-документах. Мировоззрение писателя в большой степени было сосредоточено на проблемах смерти, болезни, бренности, одиночества и старости. Сквозь их призму он воспринимал как себя и своих близких, так и весь окружающий мир, что нашло свое проявление в дневниках и письмах. Несмотря на сопутствующий писателю всю жизнь страх смерти, в своих размышлениях о человеческой судьбе он соединял мотивы фатализма и жизнеутверждения.
