Full textThe “Death with Dignity Act,” if passed in November 2012 in Massachusetts by means of a ballot initiative, would have allowed doctors to prescribe lethal drugs to patients with fewer than six months to live. Introduced by two pro-assisted suicide organizations from the Pacific Northwest, the initiative was expected to take advantage of a political “perfect storm” brewing in the Bay State. A blue state in a presidential election year, with President Obama at the top of the Democratic ticket, Massachusetts was expected to produce an electoral outcome favorable to assisted suicide. Oregon and Washington State had legalized physician-assisted suicide in 1998 and 2008, respectively. Polling in 2011 showed a 2-1 majority among Massachusetts voters in favor of assisted suicide. Nonetheless, the Archbishop of Boston and the Bishops of Worcester, Fall River and Springfield, organized as the Massachusetts Catholic Conference, took up the challenge to oppose the initiative. Relying on the expertise of paid political consultants, they mounted a two-tiered campaign. An internal component, directed at Catholics, included the dissemination of over 2 million pieces of in-print and electronic materials urging a “no” vote on the measure. An external component, directed at the wider public, relied on a coalition of organizations representing the three major religions, health and hospice organizations, disabilities rights activists, and pharmacists. Using “flaws” in the bill identified through strategic polling, they appealed to voters even sympathetic to assisted suicide to reject the bill. When the votes were counted 2.7 million Massachusetts citizens voted on the physician-assisted suicide initiative and it was defeated by 67,891 votes, 51.1% to 48.9%. One key to the defeat was the split in the vote in the city of Boston, where Question 2 was defeated 50.9% to 49.1% . Twelve of Boston’s 22 wards voted against the measure. Leading the way among the twelve were Dorchester, Roxbury, and Hyde Park, traditionally black, liberal Democratic strongholds. This study shows that even the most effective, well-funded, Church-initiated campaign in Massachusetts in 2012 might well have foundered on the 2-1 majority in favor of assisted suicide at the polls, not for the strategic identification of “flaws in the bill,” the broad-based coalition campaign based on them, and the “split in the vote in the black community in Boston.”

Full textBackground: Different countries have different euthanasia laws, in Sweden it is still an illegal practice. Patients who decide to end their lives with euthanasia/assisted death are usually terminally ill. The complexity with euthanasia includes ethical issues, personal values, health care principles, patient’s autonomy and how it should be applied in practice. The nurse is responsible for nursing and thereby has a close bond to the patient and his/her’s family. A lot of people suffer at the end of life and nurses are faced with difficult questions about death and wishes how they want their lives to end. Aim: To illustrate nurses’ experiences and attitudes to euthanasia/assisted suicide. Method: A literature review based on eleven scientific articles with qualitative design. Two databases were used, PubMed and CINAHL. The studies have been reviewed and analyzed; the used method was content analysis.Findings: Two main themes and eight sub themes were found. Under the first theme Communication the sub themes were; Understanding and helping the patient, Collaboration and support in the team, Nurses’ participation in the euthanasia process, Supporting the patient when euthanasia is granted and Nurses’ support to relatives. Under the second theme Attitudes the three sub themes were; Attitudes for euthanasia/assisted death, Attitudes against euthanasia/assisted death and Uncertainty in the issue of euthanasia/assisted death.Conclusion: Euthanasia/assisted death is complex and stirs a lot of emotions. The facing difficulties are dealt with through communication and interdisciplinary teamwork. Though nurses’ opinions about euthanasia/assisted death are divided they will always be faced with end of life nursing.

Full textAim. The aim of the study is to highlight Dutch nurses’ opinions about assisted death. Background. Since 2002 it has been legally justified for physicians to assist a patients’ death in the Netherlands. Public and ethical debate, scientific research, guidelines for prudent practice and legislatures focus predominantly on the role of physicians, seemingly assuming that the tasks of other health care professionals are less important. Though, the nurse cares for the patient on a daily basis, and has a close relationship with the terminally ill and their next of kin. Method. A qualitative method was used. Twelve nurses were used in the study, and they received a questionnaire with open questions where they were supposed to motivate their personal opinions related to assisted death. Results. Three main categories (and seven sub categories) highlights the nurses’ opinions; the meeting (discussion, next of kin), inner conflicts (religion, participation) and influences (pain relief, living will, laws and criteria). Conclusions. The Swedish taboo concerning assisted death need to be removed. The quality of the palliative care is decisive of when the patients’ request of assisted death is putted. Continuous discussion elicits underlying factors of why a request of assisted death is putted.
Syfte. Syftet med studien är att belysa nederländska sjuksköterskors personliga åsikter om dödshjälp. Bakgrund. I Nederländerna har det varit lagligt för läkare att assistera en patients död sedan 2002. I den allmänna och etiska diskussionen kring beslut som rör läkarassisterad död, i forskningen, i riktlinjer och i lagstiftning fokuseras på läkarens roll, övriga vårdgivares arbetsuppgifter antas vara mindre viktiga. Detta antagande kan ifrågasättas då sjuksköterskan vårdar patienten dagligen, ofta i en nära relation till den sjuke och hans eller hennes närstående i livets slutskede. Metod. För att uppnå studiens syfte användes en kvalitativ metod. I studien ingick tolv nederländska sjuksköterskor som fick ett frågeformulär med öppna frågor där de skulle motivera sina personliga åsikter till dödshjälp. Resultat. Resultatet visar tre huvudkategorier (och sju underkategorier) som belyser sjuksköterskans åsikt; mötet (diskussion, anhöriga), inre konflikter (religion, deltagande) samt influenser (smärtlindring, testamente, lagar och kriterier). Konklusion. Den svenska tabun kring läkarassisterad död bör tas bort för att utveckla debatten. Kvaliteten på den palliativa vården avgör ofta om och när patientens förfrågan om dödshjälp kommer. Kontinuerlig diskussion tydliggör underliggande faktorer till varför en förfrågan om dödshjälp ställs.

Full textBakgrund: År 1997 blev det lagligt för en patient med obotlig sjukdom att få hjälp att avsluta sitt liv i delstaten Oregon i USA. I Nederländerna blev detta ett lagligt alternativ 2002. I Sverige är detta inte lagligt men det pågår en debatt om legaliseringen av aktiv och läkarassisterad dödshjälp ur ett etiskt och moraliskt perspektiv. Syfte: Syftet är att identifiera faktorer till varför patienter med cancer eller ALS ber om dödshjälp. Metod: En litteraturöversikt gjordes med en analys och en sammanställning av 11 etiskt granskade vetenskapliga artiklar. Resultat: Resultatet delades in i fyra huvudteman där tre teman hade underteman. Det första huvudtemat depression och börda hade inget undertema. Det andra huvudtemat smärta har följande underteman: lidande och fatigue. Det tredje huvudtemat existentiella värderingar har undertemat: hopp och hopplöshet och slutligen det fjärde huvudtemat livskvalitet har styrka som undertema. Diskussion: Ett intresse angående en legalisering av dödshjälp finns i Sverige hos både patienter och vårdpersonal. Patientens önskan kan bli åsidosatt då ämnet är tabubelagt och genom detta kan patientens autonomi och rätten till hens självbestämmande sänkas. Patienternas inställning till dödshjälp har diskuterats utifrån teorier av Helga Kuhse, Katie Eriksson och ICN´s etiska kod.

Full textINTRODUCTION: Fetal gastroschisis is an abdominal wall defect associated with high rates of intrauterine death of unknown mechanisms. In normal fetuses, basically all computerized cardiotocography (cCTG) parameters present a significant change across gestation. OBJECTIVE: To describe the antepartum cCTG parameters between 28 to 36 weeks gestation. METHODS: Retrospective study, accomplished in the Obstetrics Department of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo - Brazil between January 2012 and June 2015, involving singleton pregnancies, with alive fetus and isolated gastroschisis that underwent to cCTG (System 8002-Sonicaid) during the antenatal care. The cCTG parameters evaluated were: number of fetal movements per hour, baseline fetal heart rate (FHR) decelerations, accelerations, episodes of high and low variation and short-term variation. A non-parametric analysis for repeated measures (nonparametric ANOVA) was used for comparative analysis of the mean distribution of each cCTG parameters throughout the study period. RESULTS: The study involved 84 pregnant women with a mean of 3.5 (1 - 9) cCTG records per patient. The number of records in each gestational age was >= 20 except for the weeks 29 (n = 16). The cCTG parameters that presented significant change during the study period were: increase in the number of records with episodes of low variation (p = 0.019); and increase in the number of accelerations higher than 15 beats per minute (p = 0.001). None of the others analyzed parameters showed significant changes during the study period, the number of movements/hr (p = 0,244), basal FHR (p = 0,606) and the STV (p = 0,145). CONCLUSION: Only two of the cCTG parameters changed significantly during the study period. Therefore, it seems that the behavior patterns of cCTG parameters, in gastroschisis fetuses, are not similar to the normal fetuses

Full textThe aim of this study was to examine the personal interest in receiving a physician hastened death among terminally ill cancer patients and the factors that are associated with such a consideration. A review of literature has been conducted on relevant articles. The evidence from a total of five qualitative studies formed the basis upon which new conclusions have been reached. The results suggest that an interest is prevalent among terminally ill cancer patients for receiving a physician hastened death. However, this is in most cases future orientated. Factors that influence patients in this consideration are the perception of being a burden to others, fear of the future, suffering, the demoralising effect that cancer has on the individual as well as religion and ethics.

Full textIntroduction: Primary hyperhidrosis consists of excessive sweating in small areas of the body. The video-assisted thoracic sympathectomy is one of the suggested treatments for primary palmar hyperhidrosis, which combines high therapeutic success with low risk. The pathophysiology of primary hyperhidrosis is not fully understood yet. Objectives: Analyzing the morphometric characteristics of the thoracic sympathetic ganglion (G3) surgically removed from patients with palmar hyperhidrosis. The sympathetic ganglion removed at the same level (G3) from patients who are organ donors after brain death and who did not have hyperhidrosis were used as control. Stereology and cellular apoptosis, as well as the fibers of the collagen/elastin system of the extracellular matrix were subjected to scrutiny. Methods: Cross-sectional study, which included 40 thoracic sympathetic ganglion (G3) removed from the left hemithorax of patients who have palmar hyperhidrosis (Group I) and underwent video-assisted thoracoscopic sympathectomy, and also 14 sympathetic ganglion from control patients who did not have hyperhidrosis (Group II), which were removed with median sternotomy. Results: In regards to gender , the proportion of women to men was 30:10 in Group I and 7:7 in Group II, with p = 0.103. The age Group I ranged from 10 to 42 years, with an average of 23.73 (+ 7.51) years and in Group II, from to 17 to 68 years, with an average of 37.57 (+ 16.65) years, with p = 0.009. The average of ganglion cells in Group I was 14.25 (+ 3.81) and in Group II, 10.65 (+ 4.93) with p = 0.007. The average ganglion cells stained by Caspase (apoptosis) in Group I was 2.37 (+0.79) and in Group II, 0.77 (+ 0.28) with p = 0.001. The median collagen area by Picrosirius in Group I was 0.80 IQ (0.08-1.87) and in Group II, 2.36 IQ (0.49-5.98) with p = 0.061. Conclusions: Patients with primary palmar hyperhidrosis have an increased number of ganglion cells in the sympathetic ganglion in comparison to the control group. There are a higher number of sympathetic ganglion cells in apoptosis in hyperhidrosis. Patients with hyperhidrosis have less collagen in sympathetic ganglion

A tese apresenta a terminalidade humana assistida em ambientes de alta tecnologia médica como um novo fenômeno social, médico e tecnológico. Discute a experiência do assistir ao morrer, o papel do médico, impacto da tecnologia usada, os atuais modelos para o diagnóstico clínico da morte. Sugere práticas assistenciais para a Boa Morte e examina suas bases morais e cognitivas. Aborda as perspectivas filosóficas, científicas e sociais do tema com ênfase na análise reflexiva dos fenômenos vividos na prática médica. A metodologia foi a revisão e análise histórico-crítica dessas práticas, e as raízes norteadoras filosóficas e científicas. O conteúdo tem três capítulos, antecedidos pela introdução e se completam nas conclusões. Na introdução uma entrevista médica inicia o tema com as dificuldades do morrer assistido. O primeiro capítulo mostra a evolução sociocultural da terminalidade humana, o papel do médico e da tecnologia. No segundo capítulo descreve-se, seguida de análise e interpretação, as vivências do processo da morte pelos que assistem o moribundo e o impacto das mesmas no processo. A análise crítica dos modelos de diagnóstico da morte está no terceiro capítulo, contrapondo fundamentos com a prática clínica. A conclusão discute as práticas médicas para a Boa Morte em seus prós e contras. No primeiro capítulo se conclui que a heteronomia acaba por fragmentar a percepção da morte. No segundo que a morte é um processo tríptico de difícil percepção na terminalidade em UTI. O terceiro capítulo nega os modelos biológico e neocortical para diagnóstico da morte humana.
This dissertation presents assisted human terminal condition in high-tech medical environments as a new social, medical and technological phenomenon. It discusses the experience of assisting death, the doctor's role, the impact of technology used and the current models for clinical diagnosis of death. The text also suggests care practices for Good Death and examines their moral and cognitive bases, addressing philosophical, scientific and social perspectives on the topic, emphasizing reflective analysis of the phenomena in medical practice. The methodology was a review and a historical-critical analysis of these practices and their philosophical and scientific roots. The dissertation is divided in three chapters, preceded by the introduction and followed by the conclusion. There is also an article attached. In the introduction, a medical interview starts tackling the theme concerning the difficulties of assisted dying. The first chapter shows the sociocultural evolution of the human terminal condition and the role of medical staff and technology in the process. The second chapter describes the experiences of the dying process by those who assist the dying and their impact on the process. The third chapter presents critical analysis of death diagnosis models, contrasting fundamentals with clinical practice. The conclusion discusses medical practices for Good Death, with its pros and cons. The conclusion brings some ideas of each chapter: based on the first chapter, it is concluded that heteronomy ultimately fragment the perception of death. In the second chapter, the conclusion is that death is a triptych process, difficult to understand in an ICU. Finally, the third chapter denies the biological and neocortical models for diagnosis of human death.

Full textIn the context of studying biological alterations occurring post impact to the central nervous system, my thesis was focused on studying the proteomic and lipid changes occurring post injury to the brain and spinal cord. A fundamental spatio-temporal study was conducted on an open-head rat TBI model to identify potential injury-specific markers. Using MALDI MSI, we performed 3D reconstruction of the injured brain at 3 days after injury and depicted lesion-specific m/z lipid molecules. After, MALDI MSI was applied on the acute/sub-acute time frame post impact: 1 day, 3 days, 7 days, and 10 days. In parallel, a microproteomic analysis was carried out on tissue segments directly consecutive to the imaged ones in an approach to correlate both lipid and protein changes. Our results yielded the identification of a family of lipids, acylcarnitines, which are expressed within the injured cortex with maximum intensity 3 days post impact. These lipid molecules also were found to be expressed in the substantia nigra and microproteomics data showed an upregulation in expression of Parkinson’s related proteins. Taken altogether, our results depict a role of link between mild-TBI and Parkinson’s disease as early as 3 days post impact, with a possible role of acylcarnitine. This same family of molecules was also present in SCI. In a therapeutic approach previous results showed RhoA protein as a major candidate post impact in SCI. After using RhoA inhibitor treatment, a proteomic study was carried out to investigate its impact on SCI. The results showed that both in-vivo and in-vitro treatment with RhoA inhibitor stimulated neurite outgrowth and helped in axonal regeneration

Alignment of virtual elements to the real world scenes (known as detection and tracking) relying on features that are naturally present on the scene is one of the most important challenges in Augmented Reality. When it goes to complex scenes like industrial scenarios, the problem gets bigger with the lack of features and models, high specularity and others. Based on these problems, this PhD thesis addresses the question “How to improve object detection and pose estimation from natural features for AR when dealing with complex scenes problems?”. In order to answer this question, we need to ask ourselves “What are the challenges that we face when developing a new tracker for real world scenarios?”. We begin to answer these questions by developing a complete tracking system that tackles some characteristics typically found in industrial scenarios. This system was validated in a tracking competition organized by the most important AR conference in the world, called ISMAR. During the contest, two complementary problems to tracking were also discussed: calibration, procedure which puts the virtual information in the same coordinate system of the real world, and 3D reconstruction, which is responsible for creating 3D models of the scene to be used for tracking. Because many trackers need a pre-acquired model of the target objects, the quality of the generated geometric model of the objects influences the tracker, as observed on the tracking contest. Sometimes these models are available but in other cases their acquisition represents a great effort (manually) or cost (laser scanning). Because of this we decided to analyze how difficult it is today to automatically recover 3D geometry from complex 3D scenes by using only video. In our case, we considered an electrical substation as a complex 3D scene. Based on the acquired knowledge from previous experiments, we decided to first tackle the problem of improving the tracking for scenes where we can use recent RGB-D sensors during model generation and tracking. We developed a technique called DARP, Depth Assisted Rectification of Patches, which can improve matching by using rectified features based on patches normals. We analyzed this new technique under different synthetic and real scenes and improved the results over traditional texture based trackers like ORB, DAFT or SIFT. Since model generation is a difficult problem in complex scenes, our second proposed tracking approach does not depend on these geometric models and aims to track texture or textureless objects. We applied a supervised learning technique, called Gradient Boosting Trees (GBTs) to solve the tracking as a linear regression problem. We developed this technique by using image gradients and analyzing their relationship with tracking parameters. We also proposed an improvement over GBTs by using traditional tracking approaches together with them, like intensity or edge based features which turned their piecewise constant function to a more robust piecewise linear function. With the new approach, it was possible to track textureless objects like a black and white map for example.
O alinhamento de elementos virtuais com a cena real (definido como detecção e rastreamento) através de características naturalmente presentes em cena é um dos grandes desafios da Realidade Aumentada. Quando se trata de cenas complexas, como cenários industriais, o problema se torna maior com objetos pouco texturizados, alta especularidade e outros. Com base nesses problemas, esta tese de doutorado aborda a questão "Como melhorar a detecção de objetos e a estimativa da sua pose através de características naturais da cena para RA ao lidar com problemas de cenários complexos?". Para responder a essa pergunta, precisamos também nos perguntar: Quais são os desafios que enfrentamos ao desenvolver um novo rastreador para cenários reais?". Nesta tese, começamos a responder estas questões através da criação de um sistema de rastreamento completo que lida com algumas características tipicamente encontradas em cenários industriais. Este sistema foi validado em uma competição de rastreamento realizada na principal conferência de RA no mundo, chamada ISMAR. Durante a competição também foram discutidos dois problemas complementares ao rastreamento: a calibração, procedimento que coloca a informação virtual no mesmo sistema de coordenadas do mundo real, e a reconstrução 3D, responsável por criar modelos 3D da cena. Muitos rastreadores necessitam de modelos pré-adquiridos dos objetos presentes na cena e sua qualidade influencia o rastreador, como observado na competição de rastreamento. Às vezes, esses modelos estão disponíveis, mas em outros casos a sua aquisição representa um grande esforço (manual) ou custo (por varredura a laser). Devido a isto, decidimos analisar a dificuldade de reconstruir automaticamente a geometria de cenas 3D complexas usando apenas vídeo. No nosso caso, considerou-se uma subestação elétrica como exemplo de uma cena 3D complexa. Com base no conhecimento adquirido a partir das experiências anteriores, decidimos primeiro resolver o problema de melhorar o rastreamento para as cenas em que podemos utilizar sensores RGB-D durante a reconstrução e o rastreamento. Foi desenvolvida a técnica chamada DARP, sigla do inglês para Retificação de Patches Assistida por Informação de Profundidade, para melhorar o casamento de características usando patches retificados a partir das normais. A técnica foi analisada em cenários sintéticos e reais e melhorou resultados de rastreadores baseados em textura como ORB, DAFT ou SIFT. Já que a reconstrução do modelo 3D é um problema difícil em cenas complexas, a segunda abordagem de rastreamento não depende desses modelos geométricos e pretende rastrear objetos texturizados ou não. Nós aplicamos uma técnica de aprendizagem supervisionada, chamada Gradient Boosting Trees (GBTs) para tratar o rastreamento como um problema de regressão linear. A técnica foi desenvolvida utilizando gradientes da imagem e a análise de sua relação com os parâmetros de rastreamento. Foi também proposta uma melhoria em relação às GBTs através do uso de abordagens tradicionais de rastreamento em conjunto com a regressão linear, como rastreamento baseado em intensidade ou em arestas, propondo uma nova função de predição por partes lineares mais robusta que a função de predição por partes constantes. A nova abordagem permitiu o rastreamento de objetos não-texturizados como por exemplo um mapa em preto e branco.

Full textFöljande examensarbete behandlar ämnet djupassisterad Struktur genom Rörelse (eng. SfM). Vid klassisk SfM är målet att återskapa en 3D scen, endast med hjälp av en sekvens av oordnade RGB bilder. I djupassiterad SfM adderas djupinformationen till problemformulering och följaktligen har ett system som kan motta RGBD bilder skapats. Problemet har lösts genom att modifiera en befintlig SfM- mjukvara och mer specifikt dess Buntjustering (eng. BA). Resultatet från den modifierade mjukvaran jämförs med resultatet av originalutgåvan för att dra slutsatser rådande modifikationens påverkan på prestandan. Resultaten visar huvudsakligen två saker. Först och främst, den modifierade mjukvaran producerar resultat med högre noggrannhet i de allra flesta fall. Skillnaden är som allra störst när bilderna är tagna från endast en liten sektor som omringar scenen. Data med brus kan dock försämra systemets prestanda aningen jämfört med orginalsystemet. För det andra, så minskar exekutionstiden betydligt. Slutligen diskuteras hur mjukvaran kan vidareutvecklas för att ytterligare förbättra resultaten.

Full textIn this work, the influence of both the microstructure and the load-bearing capacity of nitrided layers, formed on top of AISI D2 and AISI H13 tool steels, on adhesion and wear resistance of PVD-TiN coatings was studied. The threshold nitriding potential curves for the above mentioned steels and the optimum conditions of the pre-treatments which increased the adhesion as well as the wear resistance of the PVD-TiN were determined experimentally. By using longer nitriding times (about 11 h) and lower nitrogen contents in the gas mixture (about N2-5%vol.), it was possible to minimize the pile-up degree of the TiN/H13 nitrided substrates and, consequently, the occurrence of coatings chipping. This flaw persists when the nitrided layer is thin, due to an abrupt transition of mechanical properties at the TiN coating / steel core interface. Shorter nitriding times (about 42 min.) and lower nitrogen contents (about N2-5%vol.), on the other hand, are sufficient to guarantee a better adhesion of TiN coatings on AISI D2 tool steel, as the core of such steel possesses relatively better load-bearing capacity than the AISI H13 tool steel. The presence of a black layer at the TiN/nitrided layer interface was observed in all coatings deposited over nitrided layers produced above the threshold nitriding potential curves. This layer affects adversely the wear resistance and the adhesion of the TiN coatings. When higher loads are applied on the coated surface, egg shell type flaws easily occur.

Palliative care is the first choice of terminal care at the moment. However, there are patients who still want to die other than no natural death because of the poor life quality at terminal stage. Nor would they prefer terminal sedation, which put them to a drowsy sleep for a long time. These cases require ‘physician-assisted suicide (PAS)’, which is a legally and ethically debated issue. The aim of my dissertation is to investigate the ethical issue and the possibility of legalization of PAS especially in Taiwan and try to demonstrate that PAS is another type of medical practice, which provides a further choice of palliative care for terminal patients in order to achieve their expected quality of life and dignity. In contrast to euthanasia, PAS is morally more acceptable to be legalized. This dissertation is basically an ethical analysis of the issue with certain references to clinical studies. The meaning of PAS is quite different from ordinary suicide. The evidences showed that people who required PAS were mainly terminal cancer patients. They request PAS due mostly to unbearable physical pains, followed by loss of autonomy and dignity. Most medical practitioners, however, oppose to PAS. In this dissertation, I start from the ethical analysis of reasonable criteria of PAS proposed by Dr.T.E.Quill, and supplement them with some suggestions and modification, which would hopefully provide a standard model for the consideration of legalization of PAS. In terms of the medical care for terminal patients, I compare the differences between PAS and natural death, voluntarily stopping of nutrition and fluid, terminal sedation as well as euthanasia, and propose PAS as one possible choice for terminal care. The dissertation deliberates further on the right to death of the patient and the reasons for and against PAS in the literature. I support patients’ right and autonomy in particular their right to die at terminal stage. However, individual medical practitioner has no obligation to assist their patients to commit suicide. Laws should be established for protecting patient’s right to die. By legislation, not only the patients’ moral rights are protected, but medical practitioners could also have the choice to participate or not in PAS according to their personal values. Government has the duty to let patient’s wish for a death with dignity be honored. Furthermore, the dissertation elaborates the Confucian’s view on PAS ,my analysis is based on the basic of Confucian’s conception of the mind of ren or the unbearable mind of other’s suffering and the principle of ching-chuan to show why certain cases of PAS is permissible. Confucianism emphazise family relationship, therefore it is not only the patient’s voluntary decision should be respected, but also their family members’ participation are fully acknowledged. In terms of the pluralistic religious believes in Taiwan, death is not necessarily a bad thing. However, in case of PAS, doctor’s benevolent heart and medical skills may not be enough to carry out PAS for the patients, a long term well maintained doctor-patients relationship is essential. Therefore, in Taiwan, it would be most important to establish a good system of family doctors. The contributions of this dissertation include: (1) The proposal of possible clinical criteria of PAS. By comparing the criteria of Quill’s seven requirements with the Dignity Death Act, I propose a possible PAS for Taiwan. (2) The argumentation of PAS in Confucian terms shows that Confucianism tends to support PAS for terminal painful patients. For Confucianism, it is most important to let the medical practitioners, the patient and patient’s family feel peaceful. Death could be the regarded as the practice of ren if the terminal patient understands his/her own illness, and chooses PAS with family support. This should also be based on a long term well-established doctor-patient relationship, so that all parties feel peaceful for the decision. (3) According to my clinical study and observation on medical professionals in Taiwan, less than half of the physicians and nurses support the idea of legalizing PAS. (30% of physicians and 39.3% of nurses support PAS legalization). 10-14.3% of physicians and 9.2-12.8% of nurses had the experiences of being requested for PAS by patients or their family members. Obviously, although PAS is still not widely accepted by the medical practitioners, some terminal patients demand for this treatment. To carried out patient’ PAS, we need the support of the wider society as well as medical practitioners’ recognition of PAS as part of palliative care.

Full textA morte assistida é um assunto controverso de enorme delicadeza que tem sido alvo de debate nos últimos tempos, necessitando portanto de um amplo estudo.Com o objetivo de tornar esta discussão mais construtiva, começarei por esclarecer os conceitos que nos permitem perceber melhor a base em que assenta toda esta discussão.É de extrema importância cada um de nós refletir sobre o bem vida e, o valor máximo que tem para cada um, sendo de questionar se será ético deixar um doente terminal que se encontra em efetivo sofrimento à espera do momento que tem como certo, a morte.Assim falar da livre escolha ao níveis dos cuidados de saúde, será afirmar que nada poderá ser feito contra a vontade do doente terminal, devendo no entanto, ser respeitado o direito de objeção de consciência a que os especialistas de saúde têm direito.Não podemos deixar que neste processo, não se respeite a autodeterminação do paciente, optando ele por entregar-se aos cuidados paliativos ou, por outro lado optando por antecipar a sua morte.Apesar das várias posições e opiniões, é necessário que todos os padrões de atuação médica estejam bem definidos, de forma clara e precisa, tendo sempre em vista a defesa dos melhores interesses do doente.De fazer referência as propostas legislativas que neste momento se encontram “em cima da mesa”. Aprovando a morte assistida dar-se-á a possibilidade de cada um decidir como entender sobre a reta final da vida, ninguém fica obrigado a ela recorrer mas também ninguém estará impedido de o fazer.
Medically assisted death is a delicate subject that has been fuelling discussions and making headlines in recent times, showing the need for a deeper study.Aiming a more constructive exposition, I will star by clarifying the definitions that lay the foundation for all the discussion.It is of a great importance that each and every one of us reflect about the legal interest “life” and it´s maximum value for each person, questioning the ethical nature of letting a terminal patient waiting in suffer for a sure death.Therefore, talking about a freedom of choice in health care is stating that nothing can be done against the terminal patient´s will without ever disregard the health care providers’ right of being conscious objectors.We cannot allow the violation of the right of self-determination of the patient when in this situation, being his choice to submit to palliative care or to anticipate his death.Despite the several opinions and standings, a precise and clear definition of the medical intervention parameters is imperative. Only that way we can assure the best interest of patient.Acknowledging the legislative proposals on the table right now, the approval of medically assisted death will give the opportunity for each person to decide about the final stage of their lives. It will not be an obligation but it will also not be out of reach.

Full textThis study intends to be a reflection on themes such as human dignity and the end-of-life patient, associating concepts such as euthanasia and palliative care. It presents the problems of euthanasia, medically assisted death, and its development throughout history. In a brief observation of the world legal panorama, particularly of our Portuguese reality, legislative proposals and opinions about this practice are indicated, which are not always consensual, because it deals with sensitive issues such as the suffering caused by incurable diseases, the patient's autonomy, the power of decision in the terminal phase of life, especially the preference for the practice of medically assisted death. The Catholic Church, through its doctrine, fights for the defense of human life, its dignity in all situations, especially at its end. Based on Sacred Scripture and the Magisterium, it presents a Christian view of human life, recognizing in it a sacred reality. Therefore, it condemns practices such as euthanasia, and supports the loving and close care provided by palliative care. They are true instruments that provide a process of dying with all dignity. This is a descriptive-reflective study, which seeks to highlight, based on the existing literature review, especially in the documents of the Catholic Church, the importance of caring for the suffering person, until the end, contrasting practices such as euthanasia and palliative care.

This thesis proposes an effective error concealment algorithm of whole frame loss on color information for three-dimensional video encoding and transmission. Based on the motion vector extrapolation of previous reference frame, the depth-assisted algorithm can provide better error concealment result. The first part of this thesis is to pre-process Intra block of previous reference frame. The motion vector is set to zero for the previous literature. We give the appropriate motion vector for the Intra block of previous reference frame by utilizing the surrounding motion vectors and the corresponding depth information. The second part of this thesis is to propose a new motion vector selection algorithm on error frame according to the depth and extrapolated motion vector information. Experimental results show that the proposed algorithm provides better subjective and objective video qualities than the previous literature.

This paper develops an approach for image triangulation from point cloud. This approach can be divided into three parts: reconstructing environment, virtual images database establishment and triangulation. During constructing virtual images database, we can acquire extra localization information which traditional image localization lacks. When camera is far from scene or camera is sheltered by objects, traditional SIFT localization may decrease the accuracy. Our approach provides higher localization accuracy and coverage ratio by choosing better camera angles and positions automatically. In experiments, we take practical localization by traditional SIFT localization and virtual images triangulation to compare result.

Background subtraction is an important process to extract foreground objects for real-time analysis, such as tracking and recognition. The major task in background subtraction is to generate a background model which is then subtracted from the frame to extract the foreground objects. In this thesis, we propose a novel background modeling algorithm that utilizes color and depth information to generate two background models for subtraction, with one background model based on the depth information only. The generated background models are, respectively, subtracted to obtain the color and depth foregrounds which are then combined to yield the final foreground objects. The proposed method can substantially remove the noise while preserving the details, especially in high-traffic area. Empirical results showed that the proposed method outperforms the existing background subtraction algorithms in both quantitative and qualitative measures.

Stereo matching algorithms attempt to generate the depth information from stereo image pairs captured by dual or multiple cameras. Although many advances have been made for the optimization of the stereo matching quality, there are only few researches addressing the development of low complexity flow for very large scale integration (VLSI) realization. In this thesis, we proposed a low complexity stereo matching algorithm and its efficient hardware implementation. To obtain better quality, the window size should be large enough in many window-based stereo matching algorithms while large window inducing the hardware cost dramatically. Instead of adopting large window, small matching window combined with depth reliability is utilized in our algorithm which achieves good depth quality and low hardware complexity. Several hardware cost reduction methodologies are also proposed in this thesis, an area efficient memory-merging technique is applied for 32.7% storage area saving. Moreover, processing elements (PEs) consist common computations are shared in the parallel architecture which acquiring 73% PE cost reduction. Synthesis results report the gate-count and memory size is 183k and 6.72kB, respectively. The operation frequency is 166 MHz. and can support 71fps for image size of 480×540 (2×2 downsampling of Full HD side-by-side 3D format) with 56 disparity range levels.
