This thesis aims to explore what are the main factors for designers to consider, when they design persuasive technologies for improving environmentally sustainable behavior. This paper starts out with a definition of sustainability as such, while also describing the most pressing issues within ecological sustainability. The biggest part of related research is dedicated to the persuasive technologies and three main factors of ability, trigger and motivation. We also talk about a fourth, additional factor of an emotional relationship. Besides persuasive technologies, this part describes sustainable Human-Computer Interaction, location-based services, and ethical issues are mentioned as well. The first part of the next section is dedicated to the description of a High Fidelity prototype of persuasive mobile application. The second part talks about quantitative and qualitative methods used while collecting data. After that, the reader is presented with the study results, which are then also analyzed. The following part discuss these results in a more depth. In the end, we summarize obtained results and the whole study.

Pregnancy is a period full of changes. The perception of life values by the woman and her partner are varied, changes in the life style are encountered and their roles in the life are also altered. The pregnant woman feels that nothing will be like before. She is very sensitive and also easily vulnerable. Contrastingly to the routine prenatal care, prenatal psychology searches for answering questions what the feelings in the pregnancy are in terms of the psychosocial situation, and what the impacts of this course on the newborn condition after the delivery are. The scope of the work is aimed at the importance and forms of the prenatal attachment, course and its impact on the newborn. The targets of the Diploma Work entitled "Effects of the psychosomatic situation of pregnant women on the child prenatal development" are as follows: 1) to assess the pregnant woman psychosomatic situation, 2) to evaluate the influence of psychosomatic situation on prenatal development of child 3) to determine the measure of the pregnant woman (dis)comfort throughout three trimesters and 4) to evaluate the newborn condition after the delivery. Thirty pregnant women were addressed. Fifteen women reflected on the proposal and agreed with completing an anonymous standardized scale. The respondents were contacted within a period of February 2017 to February 2018. The research sample group included the women and their newborns. The choice was intentional. The women completed the Freybergh scale, which is focused on monitoring the psychosocial situation of pregnant women. It comprised 70 questions divided into seven categories. They were answered through the mediation of a compiled web reference at http://mail.scac.cz/mrIWeb/mrIWeb.dll?I.Project=V31_TEHOTENSTVI_PORIZOVANI. The statistically processed results indicated the measure of the deprivationof pregnant women in particular trimesters and condition of the newborn after the delivery based on the pregnancy experienced. The Atlas programme was employed for the qualitative research to develop an anchored statement. From the sample group of 15 women and their 405 answers, 2% of answers were recorded corresponding to an intermediate degree of deprivation. Every respondent suffered frommild deprivation. The results of the present study will find their applications particularly to branches of prenatal psychology and gynaecology. They will serve as pilot results for a CEP project planned.
