Teorie mravních citů a odkaz Adama Smithe v současné filosofii / Theory of Moral Sentiments and Adam Smith's Legacy in Contemporary Philosophy

BUKÁČKOVÁ, Tereza January 2017 (has links)
This thesis deals with the theory of moral sentiments as put in Adam Smith's work. The thesis reflects the legacy of Adam Smith and enlightened sentimentalism as whole in field of contemporary philosophy and sociological science. Hence the thesis gives attention to misinterpretations of Smith's work, to his economical heritage with emphasis on Hayek's elaboration of the theory of spontaneous order (which has foundation in the notion of the "invisible hand") and also to his legacy in political philosophy. Here the thesis introduces particularly the debate on reflective autonomy, which is crucial for the lining of fundamental features of the disagreement between rationalistic and sentimentalistic account of the origin of morality, and tries to advocate the significance of sentimentalistic claims in todays society. The aim of this thesis is to convince the reader that the aspects of our mind, which the theory of moral sentiments and sentimentalism emphases and which are rather overlooked or devalued in todays world, are absolutely necessary in public debate.

System for Recognition of 3D Hand Geometry / System for Recognition of 3D Hand Geometry

Svoboda, Jan January 2014 (has links)
V posledním desetiletí došlo ke zvýšení zájmu o užití 3D dat k biometrické identifikaci osob. Možná vůbec největší výzkum proběhl v oblasti 3D rozpoznávání podle obličeje, přičemž je v současné době dostupných vícero komerčních zařízení. V oblastni rozpoznávání podle 3D geometrie ruky byl v minulých letech proveden určitý výzkum jehož výsledkem však nebylo žádné komerční zařízení. Nezávisle na tomto výzkumu se v posledních letech velmi rozšířil trh s cenově dostupnými 3D sensory, což potenciálně umožňuje jejich nasazení v mnoha typech biometrických systémů. Hlavním cílem této práce je vytvořit funkční vzorek bezdotykového systému pro rozpoznávání osob podle 3D geometrie ruky, který bude používat novou levnou kameru RealSense 3D vyvíjenou v současné době firmou Intel. Jedním z problémů při použití RealSense kamery je její velmi malý form factor, který je příčinou nižší kvality výsledných snímků v porovnání s velmi drahými alternativami, které byly použity v již dříve zmíněném výzkumu 3D biometrických systémů. Práce se snaží analyzovat robustnost různých 2D a 3D příznaků a vyzkoušet několik různých přístupů k jejich fúzi. Rovněž je vyhodnocena výkonnost výsledného systému, kde je ukázáno, že navržené řešení dosahuje výsledků porovnatelných se state-of-the-art.

Vestavěné zařízení pro řízení robotické ruky / Embedded Device for Robotic Arm Control

Kyzlink, Jiří January 2020 (has links)
This diploma thesis deals with a design and implementation of an embedded device (module), used to control a robotic manipulator. The module instructs servomotors of the manipulator to move according to the commands received via USB interface. The module consists of two double-sided printed circuit boards. The first one allows connection to the CAN bus, redundant and thus reliable power supply for servomotors as well as the whole module. The second board, compute oriented one, embeds powerful microcontroller used to communicate with the servomotors and to solve the kinematics tasks. As a part of the thesis a graphical user interface as well as a web-oriented interface were developed. Both interfaces allow full control of the manipulator. All the communicating buses, tools and methods used during the design and implementation phases of the work are described in the thesis. Finally, measurements proved improvement of the motion smoothness and response times in several orders of magnitude in comparison to the previous system.

Uticaj sindroma gornjeg otvora grudnog koša na spavanje / Impact of Thoracic Outlet Syndrome on Sleep

Milenović Nataša 09 September 2016 (has links)
<p>Uvod - Etiologija sindroma gornjeg otvora grudnog ko&scaron;a (thoracic outlet syndrome- TOS) je udruženost vi&scaron;e faktora koji su posledica naru&scaron;avanja anatomsko-topografskih odnosa u nivou gornjeg otvora grudnog ko&scaron;a: kostoklavikularnog prostora, prednjeg skalenskog otvora, kao i same mehanike rebarnih zglobova i hrskavica, koji dovode do suženja prostora kroz koje prolaze neurovaskularne strukture, njihove kompresije, a samim tim i iritacije neurovaskularnih struktura. Sindrom gornjeg otvora grudnog ko&scaron;a je kompleks simptoma uzrokovanih kompresijom brahijalnog spleta, vene subklavije, arterije subklavije i simpatičkih vlakana, koji karakteri&scaron;u bol, parestezije, mi&scaron;ićna slabost i osećaj nelagodnosti u ruci/rukama koji se pojačava podizanjem ruke/ruku ili prekomernim pokretima glave i vrata, te dovode do smanjenja funkcionalne sposobnosti ruke/ruku i pote&scaron;koća u obavljanju svakodnevnih aktivnosti. Pored toga imaju često izraženu tahikardiju, osećaj stezanja u grudima, glavobolju, vrtoglavicu, zujanje u u&scaron;ima. Navedene tegobe su izraženije ponekad noću i dovode do poremećaja spavanja (problemi usnivanja, hrkanje, ka&scaron;ljanje, osećaj toplo/hladno, apnea, poremećaj dnevno/noćnog ritma- hronotipizacija, itd). Kao posledica lo&scaron;eg spavanja moguća je pojava depresivnih simptoma. U raspoloživoj literaturi, spavanje i kvalitet spavanja se uglavnom posmatraju kroz prizmu drugih bolesti i stanja. Materijal i metode - Istraživanjem je obuhvaćeno ukupno 181 (sto osam deset jedna) osoba. Od tog broja 53 mu&scaron;karca i 128 žena. Test grupu sačinjavalo je 82 ispitanika sa dijagnostikovanim TOS, a 99 zdravih osoba/osoba oba pola koji nemaju simptomatologiju TOS, je predstavljalo kontrolnu grupu. Grupe su bile ujednačene po polu i starosti (od 18 do 65). Tokom studije ispitanici su podvrgnuti kliničkom pregledu &ndash; fizikalnom i neurolo&scaron;kom pregledu. Pregled je podrazumevao pregled posture obolelog (posmatranje mi&scaron;ića regije vrata, ramena i ruku- trofika, tonus, konzistencija, mobilnost i kontraktilnost), posmatranje promena na koži (sa posebnim osvrtom na promene boje kože, trofičkih promena kože i noktiju i temperature kože ruku - &scaron;aka), testiranje refleksa, ispitivanje senzibiliteta u regijama inervacije odgovarajućih spinalnih korenova brahijalnog spleta. Takođe vr&scaron;ena je analiza stanja uhranjenosti (telesna visina, telesna masa, indeks telesne mase) i izvođenje provokativnih testova (Adson manevar, Rus test, Halsted test, Elvi test i Kostoklavikularni test). Kao deo ispitivanja obavljeno je i radiolo&scaron;ko snimanje vratne kičme kao i pregled oscilografom. Ispitanici su imali za zadatak da ispune sledeće upitnike: Upitnik o nesposobnosti ruke, ramena i &scaron;ake (DASH), Pitsbur&scaron;ki indeks kvaliteta spavanja (PSQI), Upitnik o hronotipizaciji (MEQ), Bekov upitnik o depresiji (BDI II). Na kraju ispitanici su davali odgovore na pitanja iz vodiča za istraživača sastavljenog sa ciljem evaluacije različitih aspekata spavanja. Rezultati - Rezultati su pokazali da su upotrebljene skale dale zadovoljavajuću pouzdanost. Pokazalo se da osobe sa dijagnozom TOS pored bogate simptomatologije imaju jo&scaron; i probleme sa spavanjem. Analizom rezultata do&scaron;lo se do zaključka da osobe sa dijagnozom TOS su starije, imaju vi&scaron;e problema sa spavanjem i veću nesposobnost ruke, ramena i &scaron;ake. Nije se pokazala razlika u hronotipizaciji kod osoba sa TOS u odnosu na kontrolnu grupu. Takođe može se zaključiti da osobe koje imaju izraženu nesposobnost ruku, ramena i &scaron;ake imaju značajno veću &scaron;ansu da imaju sindrom gornjeg otvora grudnog ko&scaron;a. Ove osobe pri tom imaju i veću &scaron;ansu da razviju depresiju i poremećaj spavanja, te se zaključuje da ova dva parametra svoj uticaj na TOS ostvaruju preko problema sa funkcionisanjem ruke, ramena i &scaron;ake. Dobar prediktor za postavljanje dijagnoze TOS može biti testiranje osoba DASH skalom. Zaključak - Rezultati studije mogu biti putokaz daljim istraživanjima, koja bi otvorila vrata formiranju protokola i opservaciji kvaliteta života osoba sa sindroma gornjeg otvora grudnog ko&scaron;a, sa posebnim osvrtom na poremećaje spavanja.</p> / <p>Etiology of thoracic outlet syndrome (TOS) is an association of several factors which are the result of disruption in the anatomical-topographical relations, in the level of superior thoracic aperture: costoclavicular space, anterior scalene aperture, as well as the mechanics of rib joints and cartilage, causing narrowing of space through which the neurovascular structures pass, their compression, and thus the irritation of neurovascular structures. Thoracic outlet syndrome is a complex of symptoms caused by the compression of the brachial plexus, subclavian vein, subclavian artery and sympathetic fibres, which is characterized by pain, parasthesias, muscle weakness and a feeling of discomfort in the arm / arms, which increases with raising the arm/arms or by excessive head and neck movements leading to a reduction of functional capabilities of the hands / arms and difficulties in everyday activities. In addition, patients often have expressed tachycardia, feeling of tightness in the chest, headache, dizziness, tinnitus. These problems are more pronounced at night and sometimes lead to sleep disorders (difficulty in falling asleep, snoring, coughing, feeling hot/cold, apnea, day/night rhythm disorder - Morningness/Eveningness disorder, etc.). As a result of poor sleeping depressive symptoms may occur. In the available bibliography, sleep and quality of sleep are mainly viewed through other diseases and conditions. The study included a total number of 181 (one hundred eighty one) people. Out of that 53 men and 128 women. The test group consisted of 82 patients diagnosed with TOS, and 99 healthy persons of both genders who had no symptoms of TOS, and constitute the control group. Groups were equalled by gender and age (18 to 65). Throughout the study subjects underwent clinical examination - both physical and neurological. This included an assessment of posture of the patient (observation of muscles in region of the neck, shoulders and arms - trophic, muscle tone, consistency, mobility and contractility), observation of changes on the skin (with a special emphasis on skin colour changes, trophic changes of the skin, nails and skin temperature of arms - hands), reflex testing, sensitivity testing in regions of innervations which correspond to spinal roots of the brachial plexus. Moreover, an analysis was conducted on the body composition analysis (body height, body weight, body mass index) as well as provocative tests (Adson manoeuvre, the Roos test, Halstead test, Elvy test and Costoclavicular test). Radiology scan of the cervical spine as well as oscillograph testing was conducted as a part of the test. The subjects were asked to fulfil the following questionnaires: Questionnaire on Disabilities of the Arm, Shoulder and Hand (DASH), Pittsburgh Sleep Quality Index (PSQI), The Morningness / Eveningness Questionnaire (MEQ), Beck Questionnaire on Depression (BDI II). Finally the subjects answered questions that researcher had drawn up in order to evaluate different aspects of sleep. The results showed that the scales used were reliable. It proved that persons diagnosed with TOS in addition to numerous symptoms also had problems with sleep. By analyzing the results it was concluded that people diagnosed with TOS are older, have more problems with sleep and greater disability of arms, shoulders and hands. There was no difference in Morningness/Eveningness type in patients with TOS in comparison to the control group. It can also be concluded that people who have pronounced disability of arms, shoulders and hands have a significantly greater chance of having thoracic outlet syndrome. These persons are more likely to develop depression and sleep disorders therefore those two entities impact TOS through the problems with the functioning of the arms, shoulders and hands. A good predictor in diagnosis of TOS may be testing people with DASH scale. The study findings can serve as a guideline for further research, opening the door into forming protocols and observation of the quality of life of people with the thoracic outlet syndrome, with special emphasis on sleep disorders.</p>

Efikasnost dekongestivne i presoterapije kod pacijentkinja sa limfedemom ruke nakon operacije karcinoma dojke / Efficacy of decongestive and pressotherapy in patients with lymphedema of the arm after breast cancer treatment

Bojinović Rodić Dragana 23 September 2016 (has links)
<p>UVOD. Sekundarni limfedem ruke je relativno česta komplikacija nakon lečenja raka dojke. Iako se kompleksna dekongestivna terapija smatra &ldquo;zlatnim standardom&ldquo; &quot;, jo&scaron; uvek postoji kontroverza o tome da li dodavanje presoterapije daje bolji terapijski efekat. Stoga je cilj ovog istraživanja bio uporediti efikasnost kompleksne dekongestivne fizikalne terapije (KDFT) u odnosu na kompleksnu dekongestivnu fizikalnu terapiju sa presoterapijom na funkcionalni status, nivo bola i kvalitet života kod pacijentkinja sa sekundarnim limfedemom ruke nakon lečenja raka dojke. MATERIJAL I METODE. Prospektivna, randomizovana, paralelna, nemaskirana studija je obuhvatila 108 pacijentkinja sa sekundarnim limfedemom ruke, prosečne starosti 56,8 &plusmn; 8,5 godina, koje su zavr&scaron;ile operativno lečenje raka dojke pre 57,4 &plusmn; 46,2 meseca. One su randomizovane u 2 grupe: KDFT grupa (kontrolna) ili KDFT+presoterapija grupa (eksperimentalna). Protokol KDFT se sastojao od nege kože, manuelne limfne drenaže, kratkoelastične vi&scaron;eslojne bandaže i vežbi. Osim toga, eksperimentalna grupa je primala presoterapiju (intermitentnu pneumatsku kompresiju), 30 minuta dnevno pri pritisku od 40 mm Hg. Oba protokola su se provodila jednom dnevno, pet dana sedmično tokom 3 sedmice. Ispitanice su podučavane za nastavak samostalnog sprovođenja nege kože, manuelne limfne drenaže i vežbi, kao i za no&scaron;enje kompresivnog rukava, 3 meseca nakon zavr&scaron;etka lečenja. Mere ishoda. Obim ruke, obim pokreta u zglobu ramena, snaga stiska &scaron;ake, vizuelna analogna skala za bol, upitnik Nesposobnost ruke, ramena i &scaron;ake (DASH) za funkciju ruke i upitnik Funkcionalna analiza lečenja raka dojke dojke sa subskalom 4+ za ruku (FACT-B4+) za kvalitet života su ocenjeni pre, neposredno nakon i 3 meseca nakon zavr&scaron;etka lečenja. Za statističku obradu dobijenih podataka kori&scaron;ćene su deskriptivne metode, analiza varijanse (ANOVA) za ponovljena merenja, analiza kovarijanse, Man-Vitni test, hi-kvadrat test i Fi&scaron;erov egzaktni test, prema potrebi. REZULTATI. Od ukupno 108 randomizovanih ispitanica, analizirane su 102 (51 u svakoj grupi). Nije bilo značajnih razlika u demografskim i kliničkim karakteristikama između dve grupe. ANOVA je pokazala značajan uticaj vremena za sve ispitivane varijable (p &lt;0,01), ali ne i značajnu interakciju vreme-grupa (0,07 &le; p &le; 0,99). Tačnije, nije bilo značajne razlike između dve ispitivane grupe u stepenu smanjenja limfedema, obimu pokreta u ramenu, snazi stiska &scaron;ake, nivou bola, DASH skoru i skorovima kvaliteta života merenim FACT -B4+, na kraju tretmana, i nakon 3 meseca praćenja. ZAKLJUČAK. Dodavanje presoterapije kompleksnoj dekongestivnoj terapiji, ne doprinosi boljem ishodu lečenja kod pacijentkinja sa limfedemom ruke nakon operacije karcinoma dojke u poređenju sa samo dekongestivnom terapijom.</p> / <p>BACKGROUND. Secondary lymphedema of the arm is a relatively common complication after breast cancer surgery. Although complex decongestive therapy is considered the &ldquo;golden standard&rdquo;, there is still a controversy as to whether adding pressotherapy is of any value. Thus, the aim of this study was to compare the efficacy of complex decongestive therapy (CDT) against complex decongestive therapy combined with a pressotherapy on functional status, pain, and quality of life in patients with secondary lymphedema of the arm after breast cancer treatment. METHODS. In this prospective, randomized, parallel, non-blind study, we recruited 108 women, mean age 56.8&plusmn;8.5 years, with secondary arm lymphedema who completed breast cancer surgery 57.4&plusmn;46.2 months earlier. They were randomly assigned to a CDT group (control) or CDT+pressotherapy group (experimental). The CDT protocol consisted of skin care, manual lymphatic drainage, short stretch multi-layer compression bandages, and exercises provided by therapists. In addition to that, the experimental group received pressotherapy (intermittent pneumatic compression) for 30 minutes per day at a pressure of 40 mmHg. The treatments were administered once a day, five days a week, for 3 weeks. The subjects were instructed to continue administering the skin care, manual lymphatic drainage, compression sleeve and exercises on their own for 3 months after the end of treatment. Outcome measures. Arm circumference, shoulder range of motion, grip strength, visual analog scale for pain, Disability of the Arm, Shoulder and Hand questionnaire (DASH) for the overall arm function, and Functional Analysis of Cancer Treatment- Breast 4+ (FACT-B4+) for quality of life were assessed before, immediately after, and at 3 months after the end of treatment. The statistical analyses included descriptive methods, analysis of variance (ANOVA) for repeated measures, analysis of covariance, Mann-Whitney U- test, chi-square test, and Fisher&rsquo;s exact test, as appropriate. RESULTS. From a total of 108 subjects randomly assigned, 102 completed the entire protocol (51 in each group), and their data were analyzed. There were no significant differences in demographic and clinical characteristics between the two groups. The ANOVA revealed significant main effect of Time for all studied variables (p &lt; 0.01), but no significant group-by-time interaction (0.07 &le; p &le; 0.99). More specifically, there was no significant difference between the two groups in the degree of lymphedema reduction, shoulder range of motion, grip strength, pain, DASH score, and FACT-B4+ scores either at the end of treatment or at 3-month follow up. CONCLUSIONS. Combining CDT with pressotherapy is no more efficacious than providing CDT alone in patients who present with chronic arm lymphedema after completing breast cancer treatment.</p>
