Author(s):  
Eleni Voultsiadou

A detailed account of sponge knowledge in Greek antiquity is given on the basis of their records in the written documents of the historical periods it comprises. The analysis of the examined material revealed interesting information on various aspects of sponge biology, more or less consistent with their present scientific knowledge. The value of sponges for man at that time was evident in many of his activities, such as household, personal hygiene, pain relief, disease treatment, art and war enterprises. The significant role of sponges in medical practice is illustrated by the high number of their records in the medical works of the studied historical period. Furthermore, sponges appeared in legends, as well as in similes and metaphors that attributed their special qualities to human behaviour, various body parts or objects.

Psychiatry is the branch of medicine concerned with the diagnosis, treatment and study of psychological disorders. The role of the psychiatrist evolves to reflect developments in medicine, science and society. The scientific knowledge base required for the practice of psychiatry changes from generation to generation, but many of the fundamental principles of practice remain essentially unchanged. We attempt here to identify some of these (relatively unchanging) principles and explore their relevance to contemporary psychiatry. In particular, we focus on the work of some of the more reflective physicians of history (e.g. Sir Robert Hutchison, Sir William Osler) in order to identify and interpret principles of medical practice outlined in the 19th and 20th centuries and we explore the relevance of these conceptual frameworks to the practice of psychiatry in the 21st century.

In the history of Iran, the institution of temporary marriage is old-established. However, in different historical periods this institution had different forms and functions. Although temporary marriage did not receive public recognition among the Iranian people, this institution continues to exist in the Iranian society. The author attempts to determine the reasons for its perpetuation in the Iranian culture. Analysis is conducted on the dynamics of transformations of the institution of temporary marriage in the Iranian culture in different historical periods. The conclusions are acquired using the method of comparative-historical analysis of historical manuscripts and written testimonies. The author classifies and describes the three historical periods “Ancient Iran”, “The Initial Period of Islam prior to the Islamic Republic”, and “The Islamic Republic”. The results demonstrate that the institution of temporary marriage, which emerged on the basis of patriarchal culture of Iranian society, legitimately met individual needs, such as sexual desire, childbearing, livelihood; and social needs, such as inheritance, strengthening of social ties. In each historical period, this institution also performed special cultural functions revealed in the course of this research. There is yet no comprehensive and documented historical research, which would compare all historical periods in a single work.

The article examines the original meaning, the transformation of the concept of education in Islam and its role in the development of science and education in the Muslim civilization. Any concept or term undergoes semantic changes depending on ideological, cultural, social and other conditions in different historical periods. This applies both to the concept of education in Islam and its place in civilization. The concept of knowledge in the tribal Arab culture with limited literacy acquires a new meaning with the advent of Islam, makes a huge contribution to the theoretical definition of the systemic concept of religious and secular education and the development of scientific knowledge. Based on fundamental works on the history of education and science, the role of the concept of education in the development of the Islamic religion and Muslim civilization is evaluated. The main historical factors of accumulation, systematization and development of knowledge in the Muslim civilization are also analyzed. In particular, the ancient Greek, Indian and Persian cultures were included in the Muslim civilization, which contributed to its intellectual enrichment. The prerequisites for the increasing development of education and science in the era of the "golden age" in Islam are analyzed, the place of ancient Greek science in the Muslim civilization, which is the core of modern scientific knowledge, is assessed.

The purpose of this exploration is revealing of some characteristic, maximally peculiar features for artistically expressive, constructional nature of trombone, as the more unique, universally perfective instrumental phenomenon in the sphere of European musically performing art. The target of this denoted disquisition is also popularization of professional orchestra, ensemble and solo playing trombone in synthetic nature of modern postmodern culture. Methodology represented the scientifically investigative work is formed by author into applying of historical, comparative, axiological and structurally analytical research’s methods. The empirical methods such as association and generalization acquire the important significance. The appeal to structurally functional method in the process for studying of denoted theme has particular importance, because the role of instrument, its functional meaning in definite culturally historical period is lighting the instrument’s artistically singular traits. The scientific novelty of this investigation is conditioned by the view to biggest historically retrospective observation of the trombone’s evolution with the simultaneous detection its uniquely natural, perfectively universal constructional and artistically expressive qualities, possibilities for reflection of ideally imaginative content in reference to professional musical compositions. Conclusions. The naturally formed into constructional perfective specificity the technique of playing trombone established fundamental bases concerning universality of the instrument in duration all the period of its existence.

In Hungary healthcare finance has decreased in proportion with the GDP, while the health status of the population is still ranks among the worst in the European Union. Since healthcare finance is not expected to increase, the number of practicing doctors per capita is continuously decreasing. In the coming years it is an important question that in this situation what methods can be used to prevent further deterioration of the health status of the Hungarian population, and within this is the role of the quality approach, and different methods of quality management. In the present and the forthcoming two articles those standpoints will be summarized which support the need for the integration of quality assurance in the everyday medical practice. In the first part the importance of quality thinking, quality management, quality assurance, necessity of quality measurement and improvement, furthermore, advantages of the quality systems will be discussed.

Background:: Regeneration is the process by which body parts lost as a result of injury are replaced, as observed in certain animal species. The root of regenerative differences between organisms is still not very well understood; if regeneration merely recycles developmental pathways in the adult form, why can some animals regrow organs whereas others cannot? In the regulation of the regeneration process as well as other biological phenomena, epigenetics plays an essential role. Objective:: This review aims to demonstrate the role of epigenetic regulators in determining regenerative capacity. Results:: In this review, we discuss the basis of regenerative differences between organisms. In addition, we present the current knowledge on the role of epigenetic regulation in regeneration, including DNA methylation, histone modification, lysine methylation, lysine methyltransferases, and the SET1 family. Conclusion:: An improved understanding of the regeneration process and the epigenetic regulation thereof through the study of regeneration in highly regenerative species will help in the field of regenerative medicine in future.
