The aim: To determine whether the pig could be used as biomodel for study and reconstruction of rectal pathology for development the new approaches for prevention and treatment of rectal diseases. Materials and methods: For the research the rectum of 8 vietnamese pot-bellied pigs were used. Via macro- and microscopy the structure of mucosa coat of the pig`s and human`s rectum was compared. Results: Mucosa coat`s peculiarities of pig`s and human`s rectum in comparative aspect are described in this article. With the help of traditional methods, known as macroscopy the structure of the pig`s rectal mucosa was study and compared wih macrostructure of human`s rectum. The microstucture of pig`s rectal mucosa was study due to histological method too. The macro- and microscopy demonstrated that structure of pig`s and human`s rectal mucosa are similar and includes same structural components. Conclusions: Thus, the research proved that pigs can be used as biomodels in biomedical research for creating various new methods and applications in approaching the prevention and treatment of rectal pathology in humans.

Biomedical endeavours can be divided into three major categories: research, education, and testing. Within the context of each of these categories, activities involving whole animals have made major contributions and will continue to do so in the future. However, with technological developments in the areas of biotechnology and computers, new methods are already reducing the use of whole animals in certain areas. This article discusses the general issues of alternatives and then focuses on the development of new approaches to toxicity testing.

It is essential for businesses to keep up with the technological advances. Today nearly all the businesses depend on computer technologies and the Internet to operate as technological developments have introduced many practical methods for businesses. Yet, transformation of businesses technologically also presents new means for the criminals, which has led to new types of fraud. It is crucial for businesses to take measures to prevent fraud. Traditional methods to prevent or to detect fraud seems to be ineffective for new types of fraud in the digital era. Therefore, new methods have been used to prevent and detect fraud. This chapter reviews fraud as a form of cybercrime in the digital era and aims to introduce the methods that have been used to detect and prevent it.

AbstractThe twenty-first Century has been billed the era of “big data”, and linguists are participating in this trend. We are seeing an increased reliance on statistical and quantitative arguments in most fields of linguistics, including the oldest parts of the field, such as the study of language change. The increased use of statistical methods changes the types of questions we can ask of our data, as well as how we evaluate the answers. But this all has the prerequisite of certain types of data, coded in certain ways. We cannot make powerful statistical arguments from the qualitative data that historical linguists are used to working with. In this paper I survey a few types of work based on a lexical database of Pama-Nyungan languages, the largest family in Aboriginal Australia. I highlight the flexibility with which large-scale databases can be deployed, especially when combined with traditional methods. “Big” data may require new methods, but the combination of statistical approaches and traditional methods is necessary for us to gain new insight into old problems.

Although carcinogens can be divided into various categories, i. e. viruses, physical agents and synthetic and naturally occurring chemicals, it is the latter that give rise to the greatest concern because of their number, quantity and distribution. Present methods of testing chemicals for potential carcinogenicity rely in the main on administration of these at maximally tolerated dose levels to animals, usually rodents, for the animals’ lifetime. Such tests would be economically impractical for all chemicals to which man is exposed. New methods have recently been introduced to screen large numbers of chemicals quickly and cheaply which rely on the unifying hypothesis that all carcinogenic chemicals are electrophiles or must be converted to such by metabolism. These methods will be reviewed and compared with traditional methods of carcinogenicity testing, particularly as to their role in attempting to predict hazard to man.

The subject of this research is the works of the prominent Russian historian of education, corresponding member of the Russian Academy of Education E. G. Osovsky (1930-2004), dedicated to the analysis of schools, education and pedagogical thought of the white émigré. The article specifies the reasons for scholar’s selection of a new pedagogical topic at the turn of the 1980s – 1990s, outlines the implemented research approaches and problem fields, as well as offers the analysis of his central works. The presented in his works comprehensive analysis of the phenomenon of pedagogical emigration gave the opportunity for upcoming generations of researchers to create a holistic picture of establishment and development of schools, education and pedagogical thought of white émigré. The authors describe the key research trends of the scholar, characterize their impact upon the development of modern historical-pedagogical science and its prospects, which defines the relevance of this article. The extensive coverage of sources, introduction into the scientific discourse of the materials from personal archive of the scholar, rare publications comprise the scientific novelty of this study. The implementation of the approach based on the combination of traditional methods of historical and pedagogical science, as well as new methods of analysis (hermeneutical, contextual, microhistorical), provides the essential cross-disciplinarity and underlines the effectiveness of its application in studying the heritage of the prominent Russian pedagogues.
