We review Fermi's paradox (or the 'Great Silence' problem), not only arguably the oldest and crucial problem for the Search for ExtraTerrestrial Intelligence (SETI), but also a conundrum of profound scientific, philosophical and cultural importance. By a simple analysis of observation selection effects, the correct resolution of Fermi's paradox is certain to tell us something about the future of humanity. Already more than three quarters of century old puzzle and a quarter of century since the last major review paper in the field by G. David Brin has generated many ingenious discussions and hypotheses. We analyze the often tacit methodological assumptions built in various answers to this puzzle and attempt a new classification of the numerous solutions proposed in an already huge literature on the subject. Finally, we consider the ramifications of various classes of hypotheses for the practical SETI projects. Somewhat paradoxically, it seems that the class of (neo)catastrophic hypotheses gives, on the balance, the strongest justification to optimism regarding our current and near-future SETI efforts.

In the article according to the theory of the subject, patterns of the existence and genesis of the subject of “Vogue” and “Harper’s Bazaar” (USA) magazines was analysed, perspective of the emergence of new subjects was established, classification of the current subjects into universal and synthetic was suggested and some regularities of authorial creation of new subjects was examined. The main objective of the study is to identify patterns of existence of actual and formation of new topics in the Means of Mass Communication on the example of “Vogue” and “Harper’s Bazaar” magazines. In studying of the empiric basis of the research the method of observation is applied; in finding common themes for both publications – a comparative method was used. The method of analysis was used in the decomposition of topics into separate topics; in isolation from the features of the topic, uncharacteristic of a journalistic work – abstraction was applied. The elucidation that the subject appears as a formal verbal expression of a set of homogeneous topics was done by applying the method of formalization. The main results of the research are: obtaining the new classification of topics of “Vogue” and “Harper’s Bazaar” magazines; identification of a significant manifestation of universal themes on the pages of publications; establishment of the basic subjective (deontological) bases of formation of new subjects. A theoretical level of their knowledge will enrich science, equip practice, promote individual and world harmony.

В представленной статье кратко раскрывается смысл понятия такого явления, как принцип гражданского процессуального права, а также дана классификация принципов, уже существующих и утвердившихся в теории гражданского процесса. Авторы работы предприняли попытку разработать новую классификацию принципов гражданского судопроизводства, отличную от общепринятой, в которой ключевым фактором выступает субъект, которому эти принципы адресованы по своему содержанию. По результатам проведенного исследования выделены субъекты, которым адресованы действия этих принципов: адресованные только суду; адресованные только лицам, участвующим в деле; - адресованные всем субъектам гражданского судопроизводства в целом (общие). Можно вполне обосновано сказать, что новая классификация принципов гражданского процесса, в зависимости от субъекта имеет право на существование. The presented article briefly reveals the meaning of the concept of such a phenomenon as the principle of civil procedural law, and also gives a classification of the principles that already exist and are established in the theory of civil procedure. The authors of the work attempted to develop a new classification of the principles of civil proceedings, different from the generally accepted one, in which the key factor is the subject to whom these principles are addressed in their content. According to the results of the study, the subjects to whom the actions of these principles are addressed: addressed only to the court; addressed only to persons participating in the case; - addressed to all subjects of civil proceedings in general (general). It can be reasonably said that the new classification of the principles of civil procedure, depending on the subject, has the right to exist.

It was 1980s when the first therapeutic protein was launched in the market. It was recombinant DNAderived insulin. Since its inception, within the worldwide pharmaceutical sector, protein therapeutics has been enjoying the fastest growth, notably for the last few years. As a result it is assumed that the treatment methodology with the conventional drug therapy will be shifted towards therapeutic proteins in near future. It made revolution in the treatment of chronic diseases like cancer, diabetes, cardiovascular diseases. The major segments in protein therapeutics are monoclonal antibody, insulin, granulocyte-colony stimulating factor (G-CSF), coagulation factors etc. In this review paper we will discuss the general aspects of protein therapeutics with their advantages over small-molecule drugs, functional classification of therapeutic proteins and their uses. The pharmacokinetics of protein therapeutics, especially from the distribution and elimination characteristics of therapeutic proteins will be discussed in brief with relevant examples. The major challenges and future perspectives will also be presented in short. DOI: http://dx.doi.org/10.3329/sjps.v4i2.10433 S. J. Pharm. Sci. 4(2) 2011: 01-12

Diary literature was of interest to Ukrainian literary critics and literary critics from other countries in different years, but still most scientific studies occur in the mid-20th century. In Ukraine, the diary has been on the side-lines of the literary process for the past two decades. And only the turning points of historical events – the Revolution of Dignity and the Russian-Ukrainian war in eastern Ukraine – returned the genre to active public circulation: without exception, all the diaries of 2014-2020 were created during the crisis period, social upheavals. The relevance of the subject is explained by the need to use the latest practices to comprehend modern Ukrainian literature and, in particular, the diary genre as one of the components of modern military prose. The purpose of the study was to perform a thorough analysis of army diaries published during 2014-2020, study their genre nature, determine their distinctive features and create their general classification. Among the main methods for processing diary texts were historical-biographical, comparative historical, comparative, structural-narratological, interdisciplinary, as well as elements of hermeneutical, intertextual methods, text and discourse analysis, etc. The study presented a thorough analysis and suggested a new classification of the modern diary genre.

Abundant supplies of oil form the foundation of modern industrial economies, but the capacity to maintain and grow global supply is attracting increasing concern. Some commentators forecast a peak in the near future and a subsequent terminal decline in global oil production, while others highlight the recent growth in ‘tight oil’ production and the scope for developing unconventional resources. There are disagreements over the size, cost and recoverability of different resources, the technical and economic potential of different technologies, the contribution of different factors to market trends and the economic implications of reduced supply. Few debates are more important, more contentious, more wide-ranging or more confused. This paper summarizes the main concepts, terms, issues and evidence that are necessary to understand the ‘peak oil’ debate. These include: the origin, nature and classification of oil resources; the trends in oil production and discoveries; the typical production profiles of oil fields, basins and producing regions; the mechanisms underlying those profiles; the extent of depletion of conventional oil; the risk of an approaching peak in global production; and the potential of various mitigation options. The aim is to introduce the subject to non-specialist readers and provide a basis for the subsequent papers in this Theme Issue.

The definition and classification of the dystonias was recently revisited. In the new 2013 classification, the dystonias are subdivided in terms of their etiology according to whether they are the result of pathological changes or structural damage, have acquired causes or are inherited. As hereditary dystonias are clinically and genetically heterogeneous, we sought to classify them according to the new recently defined criteria. We observed that although the new classification is still the subject of much debate and controversy, it is easy to use in a logical and objective manner with the inherited dystonias. With the discovery of new genes, however, it remains to be seen whether the new classification will continue to be effective.

The subject of the article is the typology of national security, and controversial issues of the selection. The purpose of the article is to identify causes of a large number of security’s forms both in theory and in practice, also to analyze acts in this sphere. The methodology of the article includes analysis, synthesis, formal-legal and comparativelegal methods. The main results of the research. The author focuses on the problem of types of national security. The author investigates the national security and methodological, theoretical and legal aspects of the classification of national security’s forms. The reason for the diversity of types of national security should also be recognized as the lack of a clear classification of them. Author investigates the mechanism for detaching forms of national security in acts of the Russian Federation in the field of security and suggests that new forms of nation security (moral security and culture security) should appear in base document of strategic planning of the national security. Moral security includes cultural, ideological, informational, psychological, scientific, educational, and religious security. Cultural security in its most general form is the stable existence of culture, the protection of this sphere from internal and external threats, for example, such as the emasculation of spiritual and moral values and globalization. Conclusions. The identification of new types of national security is an objective process due to the very versatility of such a phenomenon as national security. At the same time, it should be recognized that the sphere of spirit and morality in the context of spiritual security does not belong to the legal science, but rather to the field of philosophy and religion. In this regard, their inclusion, even as an adjective, in the text of the strategic planning document raises doubts, so the use of the phrase "moral security" in legal acts in the near future, in our opinion, can hardly be expected.

The collection of Japanese prints, albums and illustrated books (ehon) in the Museum of Oriental Art in Venice is the result of the last stop in Japan of a journey to the Far East of Prince Henry Bourbon-Parma, Count of Bardi and his wife Adelgunde of Bragança, during the years 1887-1889. The gathering of more than thirty thousand objects became the core of the present collection. Among these there are about 500 illustrated books of famous ukiyoe masters, surimono, and colour prints nishikie. The creation of catalogue entries in Japanese and Italian and the analysis of each print reveals an amazing quantity of unpublished ukiyoe masterpieces and allows a division into different groups according to the subject matter. At the same time, this distinction into different genres shows an interesting tendency in the formation of the collection together with a possible new classification of the prints themselves. This study aims to shed a new light on this particular collection while focusing on a series of illustrated books by Katsushika Hokusai (1760-1848). Among these the famous volumes of the Manga, the illustrated books on warriors, an unusual album with some prints from the One Hundred Views of Mount Fuji and a selection from the five volumes dedicated to teach the artisans how to draw all kind of decorations.
