Interfaces for Faceted Search in Indexed Wikipedia

Cieľom tejto práce je študovať vyhľadávacie systémy s využitím aspektového filtra, následne implementovať vlastný systém, ktorý bude predstavovať aspektové vyhľadávanie nad indexom Wikipédie. Práca sa teda venuje existujúcim riešeniam aspektového vyhľadávania. Z existujúcich systémov a ich chýb bol navrhnutý systém, ktorý je výstupom tejto práce. Navrhnutý systém je popísaný z pohľadu návrhu aj samotnej implementácie. Výstupom je teda aplikačné a grafické rozhranie. Aplikačné rozhranie sa dá integrovať do ľubovoľného informačného systému, kde môže slúžiť aj ako pomocný viacdimenzionálny filter. Grafické rozhranie poskytuje možnosť ako sa dá aplikačné rozhranie využiť v reálnom systéme. Dôraz bol kladený hlavne na využitelnosť a jednoduchosť takéhoto systému tak, aby sa dal využiť v existujúcich informačných systémoch.Main aim of this thesis is to study existing systems of faceted search and to design own system based on faceted search in the index of Wikipedia. In this thesis we can meet with existing solutions of faceted search. From mistakes and failures of existing solutions was designed our own system, that is output of this thesis. Designed system is described in way of design and implementation. Product of thesis is application and graphical interface. Application interface can be integrated into existing informational system, where it can be used as multidimensional filter. Graphical interface provides option how can application interface be used in real system. System was created focusing on usefullness and simplicity, for using in existing information systems.

Noninvasive laser vasectomy

Development of a noninvasive vasectomy technique may eliminate male fear of complications (incision, bleeding, infection, and scrotal pain) and result in a more popular procedure. These studies build off previous studies that report the ability to thermally target tissue substructures with near infrared laser radiation while maintaining a healthy superficial layer of tissue through active surface cooling. Initial studies showed the ability to increase the working depth compared to that of common dermatological procedures and the translation into an ex vivo canine model targeting the vas deferens in a noninvasive laser vasectomy. Laser and cooling parameter optimization was required to determine the best possible wavelength for a safe transition to an in vivo canine model. Optical clearing agents were investigated as a mechanism to decrease tissue scattering during in vivo procedures to increase optical penetration depth and reduce the overall power required. Optical and thermal computer models were developed to determine the efficacy for a successful transition into a human model. Common clinical imaging modalities (ultrasound, high frequency ultrasound, and optical coherence tomography) were tested as possible candidates for real-time imaging feedback to determine surgical success. Finally, a noninvasive laser vasectomy prototype clamp incorporating laser, cooling, and control in a single package was designed and tested in vivo. Occlusion of the canine vas deferens able to withstand physiological burst pressures measured postoperative was shown during acute and chronic studies. This procedure is ready for azoospermia and recanalization studies in a clinical setting

Transportations of space, time and self: the role of reading groups in managing mental distress in the community

Background: The practice of reading and discussing literature in groups is long established, stretching back into classical antiquity. Although benefits of therapeutic reading groups have been highlighted, research into participants’ perceptions of these groups has been limited. Aims: To explore the experiences of those attending therapeutic reading groups, considering the role of both the group, and the literature itself, in participants’ ongoing experiences of distress. Method: Eleven participants were recruited from two reading groups in the South-East of England. One focus group was run, and eight individuals self-selected for individual interviews. The data were analysed together using a thematic analysis drawing on dialogical theories. Results: Participants described the group as an anchor, which enabled them to use fiction to facilitate the discussion of difficult emotional topics, without referring directly to personal experience. Two aspects of this process are explored in detail: the use of narratives as transportation, helping to mitigate the intensity of distress; and using fiction to explore possibilities, alternative selves and lives. Conclusions: For those who are interested and able, reading groups offer a relatively de-stigmatised route to exploring and mediating experiences of distress. Implications in the present UK funding environment are discussed

A systematic review of objective burn scar measurements

BackgroundProblematic scarring remains a challenging aspect to address in the treatment of burns and can significantly affect the quality of life of the burn survivor. At present, there are few treatments available in the clinic to control adverse scarring, but experimental pharmacological anti-scarring strategies are now beginning to emerge. Their comparative success must be based on objective measurements of scarring, yet currently the clinical assessment of scars is not carried out systematically and is mostly based on subjective review of patients. However, several techniques and devices are being introduced that allow objective analysis of the burn scar. The aim of this article is to evaluate various objective measurement tools currently available and recommend a useful panel that is suitable for use in clinical trials of anti-scarring therapies.MethodsA systematic literature search was done using the Web of Science, PubMed and Cochrane databases. The identified devices were then classified and grouped according to the parameters they measured.The tools were then compared and assessed in terms of inter- and intra-rater reproducibility, ease of use and cost.ResultsAfter duplicates were removed, 5062 articles were obtained in the search. After further screening, 157 articles which utilised objective burn scar measurement systems or tools were obtained. The scar measurement devices can be broadly classified into those measuring colour, metric variables, texture, biomechanical properties and pathophysiological disturbances.ConclusionsObjective scar measurement tools allow the accurate and reproducible evaluation of scars, which is important for both clinical and scientific use. However, studies to evaluate their relative performance and merits of these tools are scarce, and there remain factors, such as itch and pain, which cannot be measured objectively. On reviewing the available evidence, a panel of devices for objective scar measurement is recommended consisting of the 3D cameras (Eykona/Lifeviz/Vectra H1) for surface area and volume, DSM II colorimeter for colour, Dermascan high-frequency ultrasound for scar thickness and Cutometer for skin elasticity and pliability

Public libraries and non-users: A comparison between Manchester and Rome

This paper presents the findings of a study conducted with library managers from two major metropolitan areas, Greater Manchester in England and Rome in Italy. The study aims to compare practices, activities and policies adopted in the two cities to attract non-users, with particular attention to the approach that librarians take to resolving the non-user issue. This research also revealed differences in the way public libraries are used in the two areas. In Manchester, libraries are predominantly task orientated, offering access points for community services, whereas in Rome the focus is more on entertainment, leisure, and social events. The non-user profiles differ between cities, with non-users being mostly older teenagers and young adults in Manchester and mostly younger teenagers and pensioners in Rome. Reading groups, a key service for encouraging reading and familiarising with library facilities, are well established in England, with 90% of the libraries in Manchester accommodating one or more groups, compared to only 50% of the libraries in Rome offering usually a single group. In addition, Manchester libraries often have a range of specialised reading groups to suit a large variety of reading tastes. Libraries in both cities are aware of the need for proactive marketing and management of their web presence but should look at other countries’ strategies to expand their range of activities and programmes to attract more public
