Luiz Carlos Borges,Marilia Braz Botelho 국립민속박물관 2008 International Journal of Intangible Heritage Vol.3 No.-
The intangible heritage is not easy to present in amuseum exhibition, and this is perhaps especially so inthe case of what the 2003 UNESCO Intangible HeritageConvention terms ‘knowledge and practices concerningnature and the universe’. The Brazilian Federal Museumof Astronomy and Related Sciences (MAST), Rio deJaneiro, initiated an exhibition and educationalprogramme on this theme for International MuseumsWeek in 2004, focusing particularly on four very differentcosmologies (i.e. narratives that attempt to explain theorigin of the Universe): the Biblical story in Genesis, thecontemporary scientific ‘Big Bang’ theory, and thecreation stories of two Brazilian indigenous populations:the Tukano people of the Amazon Region, and the Guaraniof southern Brazil and some neighbouring countries. Theevent, called Myths of Origin - man and hiscomprehension of the Universe and of the planet on whichhe lives, consisted of a conceptual, sensory andeducational experience whose principal objective was tochallenge preconceptions while questioning also thevisitors’ perceptions which arise from an educationalsystem where many of these ideas are taught as absolutetruths. Following Paulo Freire’s theory of learning and anon-restrictive understanding of the sciences, we choseto present the four different narratives on an equal basisand invited the visitor to explore these withoutpreconceptions. The underlying objective was to establisha dialogue among these diverse discourses about thecosmos, which we hoped would encourage visitors to takea critical view of the sciences and the way they areinterpreted in museums.

The control of anthracnose (Colletotrichum simmondsii) during the post-harvest stage in guava fruits (Psidium guajava L.) was performed by the application of phosphites [phosphite-K (40% P2O5 and 30% K2O) and phosphite-Ca (10.7% P2O5, 3.89% Ca, and 0.5% B)] including the Carbendazim as reference, calcium chloride (CaCl2), acetyl salicylic acid (ASA), hot water (HW), and 1-methylcyclopropene (1-MCP). These treatments were applied individually or in combination each other with two or three compounds. The evaluated parameters were diameter of anthracnose lesion (DL), number of lesions (NL), and fruit quality (fresh weight loss, pH, total soluble solids, and titrable acidity]. The fruits were disinfested, inoculated, and maintained in an incubator containing fluorescent lights at 75 μmol·m-2·s-1 (25°C, 12h photoperiod) for 5 days and were then analyzed. The results showed that the DL and the NL were reduced following treatments, and that the HW (47°C for 20 min) was the strongest and the 1-MCP treatment was the least effective. The physico-chemical characteristics of fruits were affected by some treatments without compromising fruit quality. The combination of treatments was also able to alleviate the anthracnose effect on fruits compared to individual treatments and the control without affect the fruit quality. The combinations which included the HW treatment showed the best performance to control this disease, particularly when combined with the 1-MCP and phosphite.
