En jämförelse av två olika multifokala kontaktlinsdesigner och dess påverkan på den funktionella synen : En pilotstudie

Arnehov, Lowe, Johansson, Alexandra January 2023 (has links)
Syfte: Syftet med denna pilotstudie var att jämföra en center distance-design mot en center near-design på asfäriska multifokala kontaktlinser och se dess påverkan på den funktionella synen hos presbyoper.  Metod: Totalt deltog 11 deltagare i åldrarna 45-55 år och genomgick mätningar av  synskärpa avstånd och nära, stereoseende avstånd och nära, kontrastkänslighet samt läshastighet. Testerna utfördes tre gånger, en gång med deltagarens refraktiva korrektion, en gång med center distance kontaktlinser och en gång med center near kontaktlinser i en randomiserad ordning. För testerna med normalfördelad data utfördes repeated measures ANOVA, och gällande testerna med icke normalfördelad data användes Friedmans non parametric ANOVA. Resultat: Ingen statistisk skillnad kunde hittas mellan linsdesignerna i något av testerna. Varken vid testerna för den funktionella synen, eller vid tester för synskärpa. En statistisk signifikant skillnad (p<0,05)  hittades mellan linser och glasögonkorrektion vid tester för synskärpa, både vid avstånd och på nära håll, där en glasögonkorrektion gav bättre resultat.  Slutsats: Denna studie kunde ej påvisa någon skillnad mellan en center distance-design och en center near-design på asfäriska multifokala kontaktlinser vid tester gällande den funktionella synen för presbyoper. / Aim: This pilot study aimed to compare a center distance design against a center near design for aspheric multifocal contact lenses and their performance regarding visual function in presbyopes Method: 11 participants, between the age of 45-55, completed measurements in visual acuity for distance and near, stereoacuity for distance and near, contrast sensitivity and reading speed. These tests were performed three times, one time with spectacle correction, one time with a center distance contact lens design and a one time with a center near contact lens design in a randomized order. Regarding the tests with normally distributed data, a repeated measures ANOVA was conducted, and for the non-normally distributed data, a Friedman non parametric ANOVA was used. Results: No statistical difference was found between the two lens designs in any of the tests regarding visual function or regarding visual acuity. A statistically significant difference was found (p<0,05) between spectacle correction and the two contact lenses regarding visual acuity for both distance and near, where a spectacle correction performed better.   Conclusion: This study did not find any difference in the visual function in presbyopes between a center distance design and a center near design for aspheric multifocal contact lenses.

Kulturně společenské centrum u brněnské přehrady - architektonická studie objektů pro kulturně společenské i sportovní akce / The cultural and community centre near the Brno dam - the architectural design of buildings for cultural and social and sports events

Adámek, Jiří January 2010 (has links)
CULTURALLY COMMUNITY CENTER NEAR TO BRNO´S DAM (BRNO´S RESERVOIRE) – ARCHITECTURAL STUDY OF OBJECTS FOR CULTURAL SOCIALLY AND SPORTS ACTIVITIES One of most considerable recreation area in the immediate vicinity Moravian metropolis is lake called Brno's dam. Impounding reservoir with extent 252 ha was constructed on river Svratka in years 1936- 1940. Today is dam favourite recreation area with regular shipping transport. Architectural study offers new possibilities in evolution territory, whose meaning is for town of principle. Architectural solution of designed objects governs at least by two rules. Accepts current data technical possibilities of our time. Second is spirit of place, to what do earlier Latin said „ genius loci" so, to people have had reason return on put space. Endeavour is, to culturally community centre with place communicate plus people here stop on the way. Division plus placing lake and dam to the landscapes accepts view of landscape, her impact hock, her work upon architecture construction plus urbanism. Designed centre of cultural life try respect it primary objective – place and his spirit. Area be placed on left bank Kníničky's lake, near to the area called „ Sokolák". Culturally community centre is composed from two independent objects, that are together functionally connected. Axes both objects respect how current terrain, whereon are construction, so its altitude surrounding vegetation.
