Information Technology in Education : Hopes and Fears

Łaszczyk J.

International Journal of Electronics and Telecommunications

2015

Vol. 61, No. 3

261-266

Modern technologies whose development defines the beginning of the twenty-first century information civilization create entirely new possibilities for organizing and delivering educational processes. Thanks to them an opportunity for education opens up, which is a move away from the narrowly conceived encyclopaedism in education to independent work, revealing activities, and sometimes creativity. The paper will consider the benefits that can be associated with the use of IT in teaching on the one hand understood as a set of devices, on the other as education software packages. At the same time features which entails risks for the organization of teaching and learning processes as well as for themselves educated will be indicated.

The energy balance and heat exchange for newborn baby in infant care bed environment (radiant warmer) are considered. Convective and radiant heat losses from an infant in radiant warmer were studied using copper cast anthropomorphic thermal manikin and controlled climate chamber setup. The total body heat loss was measured for several mean skin and ambient temperatures, leading to total heat transfer coefficient estimation.

Rozważany jest bilans energii oraz mechanizmy wymiany ciepła dla noworodka w otwartym inkubatorze dla niemowląt. Wykorzystano miedziany antropomorficzny manekin termiczny noworodka do zbadania konwekcyjnej i radiacyjnej wymiany ciepła z otoczeniem w komorze klimatycznej. Zmierzono całkowity strumień traconego ciepła dla wybranych średnich temperatur skóry oraz otaczającego powietrza, a następnie wyznaczono konwekcyjny współczynnik wnikania ciepła.
