The purpose of this study was to compare growth following hospitalization in preterm, low birth weight infants fed their own mother's milk versus preterm, low birth weight infants of similar weight and gestational age given standard infant formula upon demand. Growth measurements were taken 40, 42, 48 and 56 weeks postconceptual age. A total of 28 healthy, preterm, low birth weight infants completed the study. Seventeen infants received standard infant formula (Similac) and 11 were breast-fed upon demand. Introduction of solid foods was delayed until the infant was greater than 56 weeks postconceptual age. Weight, length, occiptial frontal circumference, mid-upper arm circumference, triceps and subscapular skinfold measurements were obtained at 40, 42, 48 and 56 weeks postconceptual age in our nutrition follow-up clinic. Analysis of variance with feeding as well as age, sex, gestational age at birth, birth weight, birth length and birth head circumference as factors was performed utilizing Duncan's Multiple Range Test. Weight, mid-upper arm circumference, and triceps and subscapular skinfold measurements were shown to be significantly greater in infants fed formula versus human milk from birth to 40 weeks postconceptual age. Gestational age at birth and increasing chronological age was also shown to influence these measures. Statistical significance was less than the one percent level. However, no statistical or clinical differences were found in rates of growth preterm, low birth weight infants fed either human milk or standard infant formula from 40 to 56 weeks postconceptual age. Both feeding groups experienced growth within the 10 to 90th percentiles of accepted infant norms for all parameters. It was concluded that preterm, low birth weight infants allowed to be breast-fed upon demand post-hospitalization experienced acceptable rates of gains from 40 to 56 weeks postconceptual age. Use of commercial formula was not found to be more advantageous than breast feeding.

The dissertation thesis studies the extension of the context of the term model as a means of interpretation for Czech and Slovak post-conceptual works of art. Based on result of a historical excursion into the history of painting, sculpture and architecture, the thesis offers a new typology of a model which is exemplified on particular work of art of Czech and Slovak post-conceptual era in the first two decades of the 21st century. The historical part of the thesis concludes the following: model in the art is an emancipated form originating from different academic as well as layman discourse; emancipated model has a methaphorical layer and thus it reflects wide historical, cultural and social relations. The categories proposed include: a linear model, a physical model, a cognitive model and an immersive model. The linear model encompases the sketch themes and so-called visualization metaphors (graphs, charts, schemes, etc) and originates as a reaction to information saturation and complicated networks. The physical model is a form to architecture and hobby modelling, it is characterised by a simple, „sketchy“ structure reacting to social themes and individual and collective memory. The cognitive model points to the cognitive turn of the society, it evaluates the materialisation of mental space and explains the emancipated model as an open category. Finally, the immersive model interprets the medium of exhibition as a model form which is articulated by and artisitic manifesto or an architectural interference. Another form of immersion that is being discussed in the chapter about immersive models, is a photographic or 3 D computer illusion as a reaction to society‘s virtualisation. Simultaneously to theoretical-historical research, an artistic research was taking place which became the basis for the creation of different categories and typologies of model. Each proposed category thus includes a so-called author‘s note reflecting the practical part of the dissertation thesis.
