Context server on a mobile device

Da bi mobilne aplikacije lahko učinkovito nudile vse svoje storitev in jih prilagodile uporabniku, bi morale pri tem uporabiti ves kontekst uporabnika in njegove okolice. V obstoječih raziskavah to nalogo prevzema poseben kontekstni strežnik, ki skrbi za zbiranje podatkov ter posredovanje informacij aplikaciji. V primeru, da bi tak kontekstni strežnik deloval na mobilni napravi, bi bila postopoma odpravljena potreba po omenjenem sistemu. V sklopu naloge smo predlagani model kontekstnega strežnika uspešno implementirali in njegovo delovanje preizkusili s pomočjo kontekstno odvisne aplikacije, ki deluje na principu tekstovne klasifikacije uporabnikovih vnosov v spletnih iskalnikih in njegovi trenutni lokaciji. Aplikaciji omenjenih podatkov ni potrebno zajeti ročno, saj so ti ob pojavitvi novega podatka avtomatično posredovani preko kontekstnega strežnika.In order for mobile applications to efficiently offer all of their services and adjust them according to the end user, they would need to monitor all of his context and surroundings. In the existing researches this is done by a special context server which is responsible for data retrieval and transmission of information application. In the event, when the context server would work on a mobile device, the before mentioned system would gradually not be needed anymore. In the context of the thesis we have successfully implemented the proposed model of context server and tested it with a context application, which operates in the principle of text classification of user entries in the search engines and its current location. The application of this data does not need to be captured manually, since they are automatically transmitted to the server when the new data appears

Chagas' disease in patients with kidney transplants: 7 years of experience 1989-1996

Chagas' disease was present in 17.22% of persons undergoing kidney transplantation in an Argentine Hospital. The criterion for attributing reactivation of chronic Chagas' disease and transmission of Trypanosoma cruzi to grafts was detection of parasites in blood (patent parasitemia) or tissues. Reactivation was diagnosed in 5 (21.7%) of 23 recipients. Ten (43.4%) of 23 chagasic recipients without reactivation of chronic Chagas' disease had abrogation of serological reactivity. T. cruzi infection was transmitted to 3 (18.7%) of 16 non-chagasic recipients. Reactivation and infection were diagnosed by patent parasitemia or cutaneous panniculitis. For diagnosis, detection of parasites in blood and tissues had more relevance than serology. Sequential monitoring detected early reactivation and infection, permitting application of preemptive or therapeutic therapy with benznidazole, thus inhibiting, in all patients, severe clinical disease produced by a progressive and systemic replication of the parasite
