As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced.

Human milk is frequently the only food source for a newborn during the initial stage of life after birth. Milk provides not only the nutrients necessary for the infant's growth, but also ingredients that may enable the infant to thrive. Human milk oligosaccharides (HMO) are considered to be these beneficial ingredients for the health of infant. It has been reported that around 5 to 10 g unbound oligosaccharides and around 20 to over 130 different HMO are present in 1L of human milk. The suggested health mechanisms of HMO's roles in host defense are 1) blocking bacterial adhesions, 2) binding to a toxin receptor on the extracellular domain, and 3) postbiotic effect resulting from the increase of probiotics such as Bifidobacteria and Lactobacilli. Among the prebiotic oligosaccharides, mixtures of long chain fuetooligosaccharides (10%) and galactooligosaccharides (90%) in infant formula are demonstrated to increase the number of Bifidobacteria and Lactobacilli to the levels seen in human milk fed infants.
