ABSTRACT
Com o objetivo avaliar a qualidade sanitária de alimentos artesanais produzidos na região do Alto Jequitinhonha, Minas Gerais, foram realizadas análises microbiológicas em 49 amostras de alimentos artesanais e analisadas conforme recomendações da legislação vigente. A contagem de bolores e leveduras variou de 1 x 10 a 4,5 x 10³ UFC/g nas amostras de doces e de 1 x 10³ a 5 x 10³ UFC/g nas amostras de rapaduras. Coliformes a 45ºC estavam presentes nas amostras de rapadura com contagem que variou de 1 x 10 a 3 x 10 UFC/g e nas de farinha de mandioca com contagem de 1 x 10 UFC/g. A contagem média de Staphylococcus coagulase positiva em bombons foi de 3,5 x 10² UFC/g e negativa nas demais amostras, assim como a pesquisa de Salmonella sp.. Bacillus cereus apresentou contagem de 10 UFC/g somente na massa da mandioca moída. A contagem média de aeróbios mesófilos foi de 6,0 x 10³ UFC/g nas amostras de caldos de feijão e de mandioca e de 1,0 x 10² UFC/g nas amostras de macarrão massa fresca. Os resultados mostram a necessidade de adoção de praticas adequadas para produção dos alimentos artesanais, visando agregação de valores aos produtos e segurança alimentar para os consumidores.
In order to evaluate the sanitaryquality of the handicraftfood in the areaof Alto Jequitinhonha, Minas Gerais,microbiological analysis were performedin 49 samples of handicraft foodand analyzed to check if they are in accordancewith the recommendations ofthe effective regulation.

In. order to evaluate the effects of number and method of visual stimuli on simple reaction time and determine the proper number of trials, simple reaction time of the computerized test of NTOS (Neurobehavioral Test for Occupational Screening) was carried out on 240 medical students. The prominent difference was found between male and female on simple reaction time. Regarding the effect of number based on the parameters of measures and the purpose of test itself, 64 trials was considered as proper number. The mean reaction time was different according to the methods of visual stimuli, such as color and size(p<0.05). The larger and more intence visual stimuli were, the faster sim-ple reaction time was. In respect to sex, that difference was similar. But, there was no difference depending upon whether the each result of each trial was showed on the monitor. The subjects, however, showed much interest when the result showed. Further studies, including the various variables on visual stimuli, are required to compare among various studies.
