This article presents historical data and scientific conclusions regarding the history of medicine in our country. Analysis of current problems in the medical field as a result of the reforms implemented over the last three years.


This is a comprehensive, illustrated catalogue of the 200+ marine chronometers in the collections of Royal Museums Greenwich. Every chronometer has been completely dismantled, studied and recorded, and illustrations include especially commissioned line drawings as well as photographs. The collection is also used to illustrate a newly researched and up-to-date chapter describing the history of the marine chronometer, so the book is much more than simply a catalogue. The history chapter naturally includes the story of John Harrison’s pioneering work in creating the first practical marine timekeepers, all four of which are included in the catalogue, newly photographed and described in minute detail for the first time. In fact full technical and historical data are provided for all of the marine chronometers in the collection, to an extent never before attempted, including biographical details of every maker represented. A chapter describes how the 19th century English chronometer was manufactured, and another provides comprehensive and logically arranged information on how to assess and date a given marine chronometer, something collectors and dealers find particularly difficult. For further help in identification of chronometers, appendices include a pictorial record of the number punches used by specific makers to number their movements, and the maker’s punches used by the rough movement makers. There is also a close-up pictorial guide to the various compensation balances used in chronometers in the collection, a technical Glossary of terms used in the catalogue text and a concordance of the various inventory numbers used in the collection over the years.

Franz Rosenthal (1914-2003), one of the outstanding scholars of Semitic languages, Arabic and Islamic history of the past century, has described himself as an Orientalist, whose task is “to look beyond the culture in which one is rooted to other cultures whatever their geographical location with respect to Europe, in order to learn about and understand them and to try to spread the knowledge thus acquired”. This simple-sounding approach is qualified by a vast knowledge of the appropriate literary sources and a keen sense for the truly significant topic that characterize all of Rosenthal’s works. His memoir discusses these aspects, as well as the profile and outlook of Near Eastern Studies, particularly in relation to neighboring disciplines, and the roles of philology and language teaching. What is at least as interesting as this discussion is an autobiographical account of Rosenthal’s family, his school and university years in Berlin, of his emigration to the United States, and his career up to his arrival at Yale University – a memoir which illuminates his work and his convictions and which tells a story of “cruelly turbulent times” that changed the lives of many scholars and opened up new ways of scholarship.

The relationship between Maya and our calendar is expressed by a coefficient known as ?correlation? which is a number of days that we have to add to the Mayan Long Count date to get Julian Date used in astronomy. There is surprisingly large uncertainty in the value of the correlation, yielding a shift between both calendars (and thus between the history of Maya and of our world) to typically several hundred years. There are more than 50 diverse values of the correlation, some of them derived from historical, other by astronomical data. We test here (among others) the well established Goodman-Mart?nez-Thompson correlation (GMT), based on historical data, and the B?hms? one (B&B), based on astronomical data decoded from the Dresden Codex (DC); this correlation differs by about +104 years from the GMT. In our previous works we used several astronomical phenomena as recorded in the DC for a check. We clearly demonstrated that (i) the GMT was not capable to predict these phenomena that really happened in nature and (ii) that the GMT predicts them on the days when they did not occur. The phenomena used till now in the test are, however, short-periodic and the test then may suffer from ambiguity. Therefore, we add long-periodic astronomical phenomena, decoded successfully from the DC, to the testing. These are (i) a synchrony of Venusian heliacal risings with the solar eclipses, (ii) a synchrony of Venus and Mars conjunctions with the eclipses, (iii) conjunctions of Jupiter and Saturn repeated in a rare way, and (iv) a synchrony of synodic and sideric periods of Mercury with the tropical year. Based on our analysis, we find that the B&B correlation yields the best agreement with the astronomical phenomena observed by the Maya. Therefore we recommend to reject the GMT and support the B&B correlation.

The characteristic woman of Archaic Greek sculpture, the kore (pl. korai) stands proud, rigid, frontal, and omnisciently smirking at her viewer with the famous Archaic smile. She has been interpreted as an attendant, goddess, or deceased maiden, wearing representations of draped diaphanous robes, jewelry, and bearing offerings. Yet where her now clean marble surface exists once was intricately illuminated with vibrant pigments, inlaid stones, metals, and often accompanied by accessories of various materials. Recent advancements in analytical techniques have enabled scholars to delve deeper into the study of these sculptures, uncovering traces of pigments which would otherwise be left undetected. However, the image that these colours paint has yet to be thoroughly analysed and a history of intentional removal and surface cleaning has postponed a complete evaluation of the sculptures. In Attica, from the sixth to the early 5th century BCE, korai reflect stylistic progression and variation within and between archaeological contexts. A palette of colours was used to display features now lost to the modern eye. This paper examines the korai, proposing meaning through colour, patterns, and representations. Using polychrome reconstructions, spectral data, pottery, archaeological evidence, and ancient literary sources, the author interpreted the polychromy and decorative elements of Attic korai from votive and funerary contexts. Asking questions on symbolism, utility, cultural connection, and identity of the sculptures; this paper explains the use of pigments in relation to the symbolism of the sculptures and to their role in the greater framework of the Archaic Greek world.

This chapter investigates the suspicion among New Testament scholars that the author (or the authors) of the Gospel (and Epistles) of John used already written sources which he himself (or they themselves) did not write. Various models of Johannine source criticism are sketched on the basis of selected examples. The chapter delineates the weaknesses and strengths of the source-critical approach on its own terms and to draw conclusions from them for future work. The critical evaluation shows above all that the issue of the literary and non-literary (oral) pre-history of the Johannine writings (‘diachronic’ investigation of the texts) remains an important consideration in Johannes research. Nevertheless, this approach has in the future to take into account more prominently than before the final text and its design (‘synchronic’ investigation of the texts).

Resumo: O Ensino de Química no Brasil nos dias atuais segue, predominantemente, um modelo tradicional, sendo verificada a utilização de metodologias pedagógicas repetitivas de baixo potencial de aprendizagem. Nesse contexto o presente trabalho teve por intuito elaborar um plano de aula diferenciado que envolvesse conteúdos químicos, dados históricos e discussões filosóficas a partir do tema “Ares”, utilizando a demonstração investigativa como recurso didático para propiciar uma maior motivação e envolvimento dos discentes. Para se alcançar o objetivo proposto, foi realizado um conjunto de quatro experimentos, utilizando materiais de baixo custo e fácil aquisição, a saber: Peso do flogisto; Síntese do Ar Fixo (CO2); Síntese do Ar Inflamável (H2); Síntese do Ar Desflogisticado (O2). A análise qualitativa dos dados obtidos demonstrou que o formato de aula utilizado é aplicável ao Ensino Médio, tornando a aula mais dinâmica, sendo, portanto, apreciada pela maior parte dos discentes, o que possibilitou uma maior motivação desses.Palavras-chave: Experimentação Demonstrativa; História da Química; Recursos no Ensino de Química. The history of chemistry through the “airs”: an experimental contribution to chemistry teachingAbstract: The Chemistry teaching in Brazil nowadays follows, predominantly, a traditional model, being verified the use of repetitive pedagogical methodologies with low learning potential. In this context, the present work aimed to elaborate a different lesson plan involving chemical contents, historical data and philosophical discussions based on the theme “Airs”, using investigative demonstration as a didactic resource to provide more motivation and involvement of students. To achieve the proposed goal, a set of four experiments was carried out, using low-cost and easy-to-acquire materials, namely: Weight of phlogiston; Synthesis of Fixed Air (CO2); Flammable Air Synthesis (H2); Synthesis of Dephlogisticated Air (O2). The qualitative analysis of the data obtained showed that the class format used is applicable to high school, making the class more dynamic, being, therefore, appreciated by most of the students, which enabling a greater motivation.Keywords: Demonstrative Experimentation; History of Chemistry; Chemistry Teaching Resources.

<p>Northeast Thailand is known for salt production, both today and in the past.  Prehistoric salt sites are found throughout the region and ethnographic and historical data demonstrates the importance of salt as a commodity as well as for preserving and fermenting fish. This paper explores the archaeology and cultural history of salt and salt fermented fish products in Northeast Thailand and the Greater Mekong Delta region.  Using archaeological, historical and ethnographic data, it addresses how the foods we eat and our preparation methods can be deeply rooted in our cultural history and identity, and discusses the ways in which they can be studied in the archaeological record to learn about the past.</p> <p><span style="text-decoration: underline;"> </span></p>

The present contribution describes the method of work, the types of source materia] used, and the historio- graphical and historico-eismic tradition of Armenia. The catalogue' s territorial frame of reference is that of socalled historical Armenia (which included part of present Eastern Turkey, and part of present Azerbaijan). The sources belong to different languages and cultures: Armenian, Syriac, Greek, Arab, Persian and Georgian. A comparison of the local sources with those belonging to other cultures enab]es the historical and seismological I"adition of the Mediterl'anean to be "linked" with that of the Iranian p]ateau, traditionally considered as two separate areas. We analyzed historical events listed in the most recent catalogues of earthquakes in the Armenian area compiled by Kondorskaya and Shebalin (1982) and Karapetian (1991). Important and valuable though these catalogues are, they are in need of revision. We found evidence for six hitherto unrecorded seismic events. Numerous errors of dating and location have been corrected, and several new localities and seismic effects have been evidenced. Each modification of the previous catalogues has been documented on the hasis of the historiographical and literary sources and the data from the written sources have been linked with those concerning the history of Armenian cities and architecture (monasteries, churches, episcopal complexes). On the whole. the revised earthquakes seem underestimated in the previous catalogues. The aim of this catalogue is to make a contribution to the knowledge of historical seismicity in Armenia, and at the same time to underline the specific nature of the Armenian case, thus avoiding a procedure which has generally tended to place this area in a marginal position, within the wider field of other research on historical earthquakes.

The article focuses the story of the martyrdom of 60 Christian soldiers in Gaza who were executed for their refusal to convert to Islam during the Muslim inva­sion of Palestine. It is a final episode of varied Christian history of that region. Christian history of Gaza appears as complex and fascinating. In this region in the 4th century paganism was still strong but the monastic life developed in the vicinity of Gaza. Literary sources annotated the anti-Chalcedonian resistance of monastic circles in the wake of the council of Chalcedon. Christian history of the Gaza region ended dramatically with the Arab conquest in the 7th century. Just at that time a group of Christian soldiers refused the offer of the commander of the winners Muslims. The narrative of their martyrdom was preserved in a Latin translation of a Greek original. According to the text of the Passio, the Christian soldiers were executed in two groups: at Jerusalem and at Eleutheropolis. Bi­shop Sophronius of Jerusalem intervened in favor of these Martyrs and comforted them. He also gained the palm of martyrdom. The Passio in two different Latin recensions reveals a relatively neglected aspect in the history of the Holy Land during the period of heightened religious tension.
