After a hard day at work, there is nothing else like relaxing at home in one's favourite easy chair with favourite beverage and Miles Davis blowing his tunes. Many people are able to enjoy this with the traditional home stereo system. Now, however, the technology has grown to allow you to listen multi-channel music, which completely envelopes one with sound. The audio technology keeps growing at a phenomenal pace. Video is equally intriguing. With options ranging from direct view television to advanced projection systems and combined with an anvanced audio system you can have a home theater which will make you not want to go out to the movies ever again! In this presentation, I will show you how. This is truly technology to own which will reward you for all your hard work. (AU)

Schoolfeeding programmes may benefit children through the relief of hunger. There are no studies on the effects of hunger on the congitive function of malnourished children, who may be particularly vulnerable. We therefore, examined the effects of omitting breakfast on the cognitive functions of chronically undernourished children (n = 30). Malnourished and control subjects were admitted overnight to the ward on two occasions, on week apart. They received a standard dinner (940 Kcals) in the evening. By random assingment, half the children received a standard breakfast (590 Kcals) on the morning of their first visit and a placebo on their second visit. The treatment order was reversed for the other half. Tests of cognitive functioning were given at 11:00 a.m. Since the previously malnourished and the chronically undernourished children behaved similarly, they were combined and compared to the adequately nourished. In the fasted state, the malnourished group had lower scores in fluency but the adequately nourished were not affected (group x treatment, p < 0.05); whereas in arithmetic, the adequately nourished had better scores and the malnourished group was not affected (group x treatment, p< 0.05). When weight-for-height was considered, the wasted children (<90 percent expected weight-for-height) tended to do worse when fasted, and the non-wasted slightly better in short-term memory and problem-solving ability (group x treatment, p<0.05). Omitting breakfast appears to have a detrimental effect in poorly nourished children but not in adequately nourished ones. The former are therefore most likely to benefit from schoolfeeding programmes (AU)
