Like the rest of the society modern health care has to deal with the ever increasing information flow. Imaging modalities such as CT, MRI, US, SPECT and PET just keep producing more and more data. Especially CT and MRI and their 3D image stacks cause problems in terms of how to effectively handle these data sets. Usually a PACS is used to manage the information flow. Since a PACS often is implemented with a server-client setup, the management of these large data sets requires an efficient representation of medical image stacks that minimizes the amount of data transmitted between server and client and that efficiently supports the workflow of a practitioner. In this thesis an efficient wavelet representation for large medical image stacks is proposed for the use in a PACS. The representation supports features such as lossless viewing, random access, ROI-viewing, scalable resolution, thick slab viewing and progressive transmission. All of these features are believed to be essential to form an efficient tool for navigation and reconstruction of an image stack. The proposed wavelet representation has also been implemented and found to be better in terms of memory allocation and amount of data transmitted between server and client when compared to prior solutions. Performance tests of the implementation has also shown the proposed wavelet representation to have a good computational performance.

Exploring the cycloid temperament has been attempted throughout the ages by various pioneers in psychiatry, psychology and psychoanalysis. Contemporary psychiatric approaches have estimated that cycloid pathology, most evident as Bipolar Disorder, accounts for more than 1% of the population and is seen as the sixth leading cause of all illnesses. Despite the latter it is remains a desperately understudied area psychologically. Theoretically, BD is known for (1) its complex epidemiology, (2) costly treatment, (3) occupational impairment; (4) its negative interpersonal implications, (5) negative domestic effects, (6) forensic consequences, (7) death due to suicide and accidents, (8) cost in treatment, and finally, and most importantly from a humanistic perspective, (9) BD's diminished quality of life. Given the various realities faced by those suffering from Bipolar disorder the current study aimed at describing, through the use of the Rorschach Comprehensive system (CS), the self and object-representations, as well as the affect experiences of fifty, predominantly Bipolar I inpatients. The patients were selected through opportunity sampling at two provincial psychiatric hospitals in South Africa and included Caucasian, African and Colored respondents. All protocols were administered and scored by trained CS clinicians and re-scored by both the author and supervisor. Fifteen protocols were thereafter randomly assigned to three inter-raters and a high level of inter-rater reliability seemed evident. Given various inherent limitations of the study, that is, (a) a study of limited scope, (b) the heterogeneous nature of the sample and the reliance on opportunity sampling, (c) the small sample size, (d) lack of a control group, and (d) the focus of the study as exploratory-descriptive in nature, basic descriptive statistic were relied upon. Despite the various limitations, the results obtained seemed to hint at the possibility of a Neglected Self, characterised by difficulties in modulating affect in moderation, lack of self-esteem and positive self-regard, difficulties in introspection and self-inspecting behaviour, a general lack of interpersonal comfort and feelings of threat, as well as affectional and representational constriction. The presence of impaired self-regulation and reflection, possible perceptual differences in sensory-affective reactivity and processing, as well as difficulties in representational elaboration and differentiation needs further research and comparison to other psychiatric disorders. Basic therapeutic inferences were also discussed that may support those who treat cycloid patients. / Thesis (PhD)--University of Pretoria, 2012. / Psychology / unrestricted

This qualitative study examined whether a connection exists between children with emotional disorders consumption of traditional entertainment media and their subsequent vegative/anti-social classroom behavior. Research participants included six first-grade children diagnosed with an emotional disorder and their teacher. They were interviewed using a semi-structured approach. The students were observed in the natural setting of their classroom for a total of twenty-four hours, over a four-day period. Transcripts and classroom observations were analyzed, looking for connections between behavior and consumption of traditional entertainment media. Findings from this study concluded that these students used traditional entertainment media as a method of temporally escaping from the environment of their respective households.

The subjekt of this thesis is a design of a viewing tower located in the area of Brdy. The structure has been created as a 3D model, the internal forces have been calculated with the use o finite element method in a structural engineering software Scia Engineer 15.1. Based on the knowledge of theses forces the design of the structural systems has been done. The materials used on this construction are glued laminated timber and steel. The height of the tower is 25,725 m. The floor plan is a shape of a circle and fluctuating smaller with the gaining height. The main structural systém consists of 8 curved posts which are radiály situated on the circular floor plan. The tower has 3 observational platforms.

The purpose of this thesis is to create design and static assessment of the viewing tower in western Jeseníky mountains. The Ground plan is formed by regular hexagon with outer diameter 0.8 meter. Glued laminated profiles, steel tubes and elements of solid wood were predominantly used for the construction of the building. The viewing tower has four viewing platforms and total high of the structure is 28.5 meters.

Recent scholarship around the topic of 3D mainly deals with the visual developments that have occurred in the medium during the 21st century. A common perception in these strands of research is that in comparison to the production workflows employed in the analogue era, the 3D compositions that are being crafted through the aid of the ever-evolving digital technology have made 3D develop for the better. Yet a question that nevertheless remains is how the technology itself employed to craft these compositions has evolved. Rather than focusing on the visual developments, the primary aim of this thesis is to render visible the processes and operations of the stereoscopic technology employed to realise this 3D imagery in the first place. Utilising a media archaeological approach indebted to Wolfgang Ernst’s notion of “reverse engineering” technical media objects, I intend to analyse the primary technical components of digital and analogue 3D recording, projection and viewing devices utilised in the production of stereoscopic motion pictures. Moreover, Jonathan Crary’s writings on “the observer” will be used to highlight the important role of the human subject in relation to these binocular media technologies. I conclude that despite the varying production contexts and traditions the digital and analogue formats have been developed in, the primary methods and techniques that characterise digital 3D recording, projection and viewing systems are not specifications simply invented from scratch during the digital age. Through close scrutiny of the stereoscopic systems’ configurations with the aid of Ernst’s media archaeological approach, we are able to trace these supposed developments of the digital age back to the 19th century, when 3D was first realised.

Affinity 2.5 is a computer-based instrument designed to measure sexual interest using viewing time of images depicting fully-clothed males and females of different ages. Participants are asked to rate the sexual attractiveness of the person in the image according to a 15-point scale while their viewing time of each image is surreptitiously monitored. The validity of viewing time as a measure of sexual interest is based on social cognition theory and is established in the review of literature. The number of images comprising Affinity 2.5 represents a 42.9% increase from the previous version of the assessment, Affinity 2.0. The purpose of this study was to examine the temporal stability of scores on Affinity 2.5 for a sample of exclusively heterosexual, nonpedophilic males and females. Viewing time data from 63 males and 84 females were analyzed using a chi-square procedure. Results of this analysis indicate that 86% of responses from the male participants and 88% of responses from the female participants were consistent from time one to time two. As suspected, these percentages represent an increase in reliability over the temporal stability of the shorter Affinity 2.0.
