Application of three-dimensional computed tomography in craniofacial clinical practice and research
No full textFollowing the invention of the first computed tomography (CT) scanner in the early 1970s, many innovations in three-dimensional (3D) diagnostic imaging technology have occurred, leading to a wide range of applications in craniofacial clinical practice and research. Three-dimensional image analysis provides superior and more detailed information compared with conventional plain two-dimensional (2D) radiography, with the added benefit of 3D printing for preoperative treatment planning and regenerative therapy. Current state-of-the-art multidetector CT (MDCT), also known as medical CT, has an important role in the diagnosis and management of craniofacial injuries and pathology. Three-dimensional cone beam CT (CBCT), pioneered in the 1990s, is gaining increasing popularity in dental and craniofacial clinical practice because of its faster image acquisition at a lower radiation dose, but sound guidelines are needed to ensure its optimal clinical use. Recent innovations in micro-computed tomography (micro-CT) have revolutionized craniofacial biology research by enabling higher resolution scanning of teeth beyond the capabilities of MDCT and CBCT, presenting new prospects for translational clinical research. Even after four decades of refinement, CT technology continues to advance and broaden the horizons of craniofacial clinical practice and phenomics research.PJ Anderson, R Yong, TL Surman, ZA Rajion, S Ranjitka
Design of Interior Object
No full textTato práce se zaměřuje na design interiérového světla, které se typově hodí do většiny vnitřních prostor. Mělo by splňovat estetická i funkční kritéria a příjemně doplňovat pro-stor. V teoretické části se autor zabývá historií, jsou probrány zásady vnitřního osvětlování, současné technologie, práce se také zaobírá realizací a podobou moderních světel. V rámci praktické části je zkoumán postoj dnešní společnosti při výběru interiérového svě-telného zdroje. Bude také popsán vývoj nápadu od prvopočátku, který byl z autorova hle-diska nejdůležitější. Od rozboru realizací se postupně přechází ke skicám a 3d návrhům. Poté je řešen finální návrh, společně s ergonomickou a technickou dokumentací.This bachelor thesis is focused on design of interior light, which typologically suits into the most of interior areas. The interior light should fulfil aesthetic along with functional criteria and it should nicely complement an interior area. In the theoretical part author describes history, then clarifies the principles of interior lighting and current technologies. This paper work deals with the realization and form of modern lights as well. The practical part of this thesis analyzes an attitude of society nowadays when choosing the interior light source. It describes development of idea from the beginning, which was according to the author the most important part. From analysis of realizations the author progressively moves to sketches and 3d designs. At the end is given the final draft together with ergonomic and technical documentation.Ateliér Průmyslový desig
The Use of Point of Care Testing for Monitoring of APTT in Patients Receiving Heparin Infusion
No full textBackground: There is a high risk of thromboembolic events among patients undergoing cardiac surgery, and perioperative anticoagulation is sometimes required. The time taken for laboratory based APTT blood sampling results and adjustments may compromise patient safety. There is evidence in the literature to suggest that bedside testing turnaround times is of benefit to inpatient care, and conversely that POCT is inaccurate. The primary aim of this study was to determine if point of care testing of APTT was accurate when compared to laboratory based APTT measurements. The secondary aim was to identify if there was a correlation between operator experience and accuracy of results.
Methods: Following full ethics approval by the Royal Adelaide Hospital, Human Research Ethics Committee (HREC), current Cardiothoracic Surgery Unit inpatients were enrolled in the study over a period from July 2016-March 2017. A total of 50 samples were obtained from the minimum number of patients required and separated into three tiers; point of care testing group from finger prick test, point of care testing group from standard postoperative blood sample, and laboratory based testing of standard postoperative blood sample. Results were correlated with Central Adelaide Local Health Network (CALHN) heparin infusion protocols. Clinically significant samples were those which POCT IV and laboratory IV results varied enough to alter the heparin infusion protocol rate change.
Results: Demographics showed 83% of patients were male, 67% were receiving IV heparin preoperatively for unstable coronary artery disease, and the mean age of participants was 66 years. Of the 50 collected samples, 17/50 (34%) were recorded as being clinically significant. On the adjusted POCT protocol, 14/50 (28%) of samples were clinically significant. There was a statistically significant difference between POCT IV and laboratory IV results; p = 0.02 and mean difference between values was 19.1. Linear regression analysis showed a poor correlation between POCT IV and laboratory IV samples. There was no relationship between preoperative and postoperative samples. Conclusions: Point of care testing in our study of 50 patient samples shows that there is a poor correlation between POCT and laboratory based testing. Additionally, there is a steep learning curve for those performing the test with no marked improvement following progressive samples. Accordingly, POCT testing in cardiac surgery patients is not recommended for clinical use until further research is completed showing improved correlation between tests, and methods to overcome the steep learning curve are identified

No full textNotes on SuperFlat and its expression in videogames
No full textIn this exploratory essay the author describes the shared context of Sculptor turned Games Designer Keita Takahashi, best known for his PS2 title Katamari Damacy, and superstar contemporary artist Takashi Murakami. The author argues that Takahashi’s videogame is an expression of the technical, aesthetic and cultural values Murakami describes as SuperFlat, and as such expresses continuity between the popular culture and contemporary art of two of Japan’s best-known international creative practitioners

Clinical Outcomes of Orbital Trauma in South Australia
No full textIntroduction: Our primary aims are to report on the demographics of orbital trauma in Adelaide, South Australia. Our secondary aims are to demonstrate the long-term (>12 months) clinical outcomes of orbital trauma patients. Materials and Methods: Forty patients agreed to participate in the study, including 20 surgical patients and 20 non-operative patients. Patients were assessed in the areas of demographics, sensory, visual and cosmetic outcomes. Results: In the surgical patient group, 13/20 (65%) patients suffered trauma from physical assault and 16/20 (80%) were males. In the non-surgical patient group, 17/20 (85%) suffered trauma from physical assault and 16/20 (80%) were males. In the surgical patient group, sensory deficit was reported in 8/20 patients (40%), visual deficit was reported in 8/20 patients (40%), and cosmetic deficit was reported in 6/20 (30%) patients. In the non-operative patient group, sensory deficit was reported in 7/20 patients (35%), visual deficit was reported in 8/20 patients (40%) and cosmetic deficit was reported in 6/20 patients (30%). Conclusion: Our clinical study of 40 patients showed no clear clinical or statistical difference between outcomes in the two groups. Impaired visual, sensory and cosmetic deficits were reported in the minority and did not impact on quality of life
