Uso da internet em ambiente acadêmico :estudo com docentes em institruição de educação tecnológica no Brasi

The last decade, characterized by the vertiginous growth of the computers worldwide net, brought radical changes in the use of the information and communication. Internet s use at business world has been largely studied; however, few are the researches about the academic use of this technology, mainly if we take into consideration institutions of technologic education. In this context, this research made an analysis of internet s use in a technologic education institution in Brazil, analyzing, in particular, the Centro Federal de Educação Tecnológica do Rio Grande do Norte CEFET/RN for that standard use of this Information Technology (IT) tools and, at the same time, studying the determinant factors of this use. To reach the considered objectives, a survey research was effected, be given data collected daily through the research s questionnaire application to 150 teachers who answered a set of closed and scaled questions. The quantitative data were qualitatively analyzed, arriving a some significant results related to the standard use and the factors that influenced in the use of these Internet technologies, like: the age scale, the exposition s to the computer level, the area of academic graduation, the area of knowledge where acts and the title, exert significant influence in the academic use of Internet between the professors

Fatores condicionantes da utilização da Internet na compra de serviços de viagens e turismo: estudo com turistas brasileiros em visita à Natal-RN

In today s global society, companies have become even more competitive with the abundance of information that prospective clients have available to them. This way the tourist services has appropriate the distribution using electronics ways as information for doing acquirement services. This work, shows the adopted provision of on-line tourist services does have suited apportionment for factors and buy decisions. The method used is a survey applied to the tourists, at international airport Augusto Severo, no matter why the visit reason to Natal city, at all, they were 210 people, being the chief variables evaluated the tourist perception of facility, utility, benefits, amenity and pleasure from the Internet s use, under the terms at the tourists experiences from the WEB about to acquisitions and researches. The results acquaint that the younger tourists or less experts tourists, in visit to Natal, demonstrated greater bias to the Internet s use than the other people. By the way women have a larger representation as a consumer from the WEB and finally, people along greater study tends to adopt. The work s contribution provides greater knowledge for the tourism executives about how might use the Internet, as well as bring forward a scene propitious for the on-line diffuseness service

Jornalismo e narrativas transmidias: a reportagem no contexto da convergência

The transmedia storytelling is a phenomenom recently conceptualized theoretically (JENKINS, 2009), arising from ficcional mediatic products and disseminated as well by the use on other fields. This search aims to analyze how the transmedia storytellings can be applied to journalism on the basis of an specific genre, the reporting. To that, take as reference theoretical developments performed by brazilian authors (FECHINE et al., 2011, 2012, 2013), on the basis of televisive fiction, which culminated on concepts as transmediation and transmedia contents and deepened the comprehension and the research in this area. Thenceforth, this study propone a problematization and apropriation of this theoretic support for the journalism field, using, for that, a comprehension of journalistic production on a speech level, as well as its social practices (newsmaking). The empiric research also take two different paths. First, analyze a group of reportings, in which there is transmediation, in order to verifying the configuration of the transmedia phenomenom - more specifically of the transmedia storytelling - and its particularities to journalism. Then, develops an investigation, based on the etnographic method, of the productive routine on the special reporting section of the Jornal do Commercio (Recife/PE), aiming to investigate the conditions of transmediation in this range and the practices that favor and difficult the employment of transmedia storytelling. The result are, therefore, compared and related, with the goal of providing multidimensional view of the phenomenom

Tamoxifen inhibits transforming growth factor-alpha gene expression in human breast carcinoma samples treated with triiodothyronine

Influência do tamoxifeno associado ao diabete melito na densidade mineral óssea

Considering that osteopenia and osteoporosis are diabetes mellitus complications, and that tamoxifen (TAM) is an anti-estrogenic drug used in breast cancer treatment, this drug may have a beneficial action preventing accentuaded bone loss associated to diabetes. Female Wistar rats (n=60) weighting 180-250g were divided in four groups: Group C, control animals (n=5); Group T, animals treated with TAM (n=5); Group D, diabetic animals (n=5); and Group DT, diabetic animals treated with TAM (n=5). Oestrus cycle was evaluated before the beggining of experimental period to select the animals with regular cycle. This evaluation continued throughout the study period and for all studied groups. Diabetes was induced by a intra perithoneal injection of streptozotocin (STZ) in a concentration of 45 mg/Kg of body weight. Those animals with serum glicose levels 250 mg/dL were considered diabetics. Animals were sacrificed in the periods of 30, 60 and 90 days after diabetes onset. Left femur histomorphometric measurements and serum biochemical analysis (glycemia, alkaline phosphatase, tartaric-resistant acid phosphatase, calcium, phosphorous, magnesium, total proteins, albumin, globulins, urea and creatinine) were done. Histomorphometric results showed a progressive bone loss in Group D animals when compared to those from Group C all over the experimental period, becoming accentuaded in the 90 days period. In relation to Groups T and DT, values approcimated to those obtained for control group were found during the whole period of study. Those data may indicate a bone mass recovery or a diminished bone loss due to diabetes when animals were treated with TAM. During the whole experimental period animals of groups D and DT maintained glycemic levels above 250 mg/dL whereas animals of groups C and T maintained those levels below 150mg/dL. Alkaline phosphatase activity was increased in all study periods for groups D and DT when compared to group C animals over the 90 days period. Tartarate-resistant acid phosphatase activity was showed unaltered in all periods of study and for all groups. Calcium and magnesium results were also unaltered, maintaining reference levels for all groups in all experimental periods. Phosphorous levels were increased in groups D and DT when compared to groups C and T in the 30 days period. However no difference was found in the periods of 60 and 90 days for this test. No difference was found for total proteins levels for groups C, T, D and DT over the study period. Albumin levels were reduced in DT group in the 60 days period and in D and DT groups in the 90 days period. Urea levels were significantly increased in the 30, 60 and 90 days study periods in groups D and DT when compared to groups C and T. Creatinine results showed a significantly increase in the 90 days period for groups D and DT when compared to groups C and T, and maintaining unaltered in the 30 and 60 days periods. These results suggest that the treatment with TAM may reduce bone loss caused by diabetes mellitus
