    TCC (graduação) - Universidade Federal de Santa Catarina, Centro Sócio Econômico, Curso de Administração.Os planos de benefícios para as organizações, têm se tornado cada vez mais importantes como forma de atrair e reter talentos, e ainda como diferencial competitivo com relação aos concorrentes. Para os colaboradores, garante o nível mínimo de qualidade de vida, como alimentação e assistência médica, poupando-lhes esforços e preocupação, oferecidos como parte integrante da remuneração. Neste estudo procurou-se verificar a satisfação dos colaboradores do Serviço Social da Indústria em Santa Catarina, utilizando dados da pesquisa de clima organizacional, que foi realizada em setembro de 2003, bem como apresentar a Organização, os benefícios oferecidos aos seus colaboradores como forma de complemento da remuneração, descrevendo e analisando conforme a literatura estudada e também comparando com a pesquisa salarial encomendada pela empresa em outubro de 2003. A pesquisa caracteriza-se como um estudo de caso, e quanto aos fins, como uma pesquisa exploratória e descritiva. Os dados coletados são predominantemente quantitativos. Para se chegar aos resultados esperados, foi necessário, em primeiro lugar, realizar-se a fundamentação teórica dos seguintes assuntos: benefícios: definição, tipos e objetivos. Após esta etapa, partiu-se para ao estudo de caso, caracterização da empresa, suas áreas, políticas gerais, a gestão Socialmente Responsável e apresentação dos benefícios oferecidos. Após partiu-se para análise da pesquisa de clima organizacional e finalizando com a combinação dos benefícios do SESI com os oferecidos no mercado e na literatura. Pode-se concluir que o pacote de benefícios estudados da empresa atende a necessidade da maioria dos colaboradores da Organização, e que a empresa em questão oferece uma grande variedade de beneficios, de acordo com o que é encontrado na literatura e também no mercado. Vale ressaltar que o trabalho trata dos beneficios que complementam a remuneração do colaborador, ou seja o salário ganho pela função exercida, mais beneficios, que somados totalizam a remuneração do colaborador. Para a organização, ao conhecer a satisfação dos seus colaboradores, ou possíveis faixas de desagrados, pode trabalhar ações corretivas, planos de ações para verificar o que pode ser feito para melhor atender seu público interno, e não correr o risco de perder seus talentos para outras organizações. Para estes casos recomenda-se a adoção de pianos flexíveis, que são aqueles em que o profissional pode optar pelo beneficio que mais o convém

    Observation of the Dynamical Casimir Effect in a Superconducting Circuit

    One of the most surprising predictions of modern quantum theory is that the vacuum of space is not empty. In fact, quantum theory predicts that it teems with virtual particles flitting in and out of existence. While initially a curiosity, it was quickly realized that these vacuum fluctuations had measurable consequences, for instance producing the Lamb shift of atomic spectra and modifying the magnetic moment for the electron. This type of renormalization due to vacuum fluctuations is now central to our understanding of nature. However, these effects provide indirect evidence for the existence of vacuum fluctuations. From early on, it was discussed if it might instead be possible to more directly observe the virtual particles that compose the quantum vacuum. 40 years ago, Moore suggested that a mirror undergoing relativistic motion could convert virtual photons into directly observable real photons. This effect was later named the dynamical Casimir effect (DCE). Using a superconducting circuit, we have observed the DCE for the first time. The circuit consists of a coplanar transmission line with an electrical length that can be changed at a few percent of the speed of light. The length is changed by modulating the inductance of a superconducting quantum interference device (SQUID) at high frequencies (~11 GHz). In addition to observing the creation of real photons, we observe two-mode squeezing of the emitted radiation, which is a signature of the quantum character of the generation process.Comment: 12 pages, 3 figure

    Justification of the symmetric damping model of the dynamical Casimir effect in a cavity with a semiconductor mirror

    Full text link
    A "microscopic" justification of the "symmetric damping" model of a quantum oscillator with time-dependent frequency and time-dependent damping is given. This model is used to predict results of experiments on simulating the dynamical Casimir effect in a cavity with a photo-excited semiconductor mirror. It is shown that the most general bilinear time-dependent coupling of a selected oscillator (field mode) to a bath of harmonic oscillators results in two equal friction coefficients for the both quadratures, provided all the coupling coefficients are proportional to a single arbitrary function of time whose duration is much shorter than the periods of all oscillators. The choice of coupling in the rotating wave approximation form leads to the "mimimum noise" model of the quantum damped oscillator, introduced earlier in a pure phenomenological way.Comment: 9 pages, typos corrected, corresponds to the published version, except for the reference styl

    A glândula pineal foi estudada macro e microscopicamente em 19 capivaras (Hydrochoerus hydrochoeris) jovens e adultas, fêmeas e machos. A pineal, presente em todos os espécimes, estava localizada entre o cérebro e o cerebelo, e era formada por uma base com dois pedúnculos, uma haste e um ápice. A glândula localizava-se no teto do III ventrículo, próximo ao colículorostral, mostrando-se esbranquiçada ou acastanhada. O ápice continha uma cavidade. O comprimento médio da glândula na base foi de 1,3 mm; 1,2 mm; 2,0 mm na sua haste e ápice respectivamente. Revestida por uma cápsula de tecido conjuntivo contendo, pelo menos em parte do seu contorno, vasos sangüíneos, o parênquima pineal mostrou pinealócitos com grânulosnucleares e células intersticiais.The pineal gland was studied macro-and microscopically in 19 adult and young capybaras (Hydrochoerus hydrochoeris) 13 females and 6 males. Pineal gland was present in all specimens between the cerebrum and the cerebellum and was formed by a base with two peduncles, a stem and an apex. The gland was in the roof of the III ventricle, next to the rostral coliculi, eitherwhish or brownish.The apex contained a cavity. Pineal gland was 2.2 cm long, and dimensions of the base, stem and apex were 1.3 mm, 1.2 mm and 2.0 mm respectively. The connective tissue capsule at least in part, contained blood vessels. Pineal parenchyma exhibited pinealocytes, with nuclear and interstitial cells

    Imatinib mesilate (Glivec®, Novartis Pharmaceuticals) is a novel therapy for the treatment of chronic myeloid leukaemia (CML). We evaluated the cost-effectiveness of imatinib (600 mg daily) when used for the treatment of patients in advanced stages of CML (accelerated phase and blast crisis) against conventional therapies of combination chemotherapy (DAT) and palliative care in hospital or at home. A Markov model simulated the transitions of hypothetical patient cohorts and outcomes were modelled for 5 years from the start of treatment. Costs were estimated from the perspective of the UK National Health Service. Over 5 years, a patient in accelerated phase will, on average, accrue an additional 2.09 QALYs with imatinib compared to conventional therapies, while patients in blast crisis will accrue an additional 0.58 quality-adjusted life-years (QALYs) with imatinib compared to conventional therapies. The costs per additional QALY gained from treatment with imatinib compared with conventional therapies were £29 344 (accelerated phase) and £42 239 (blast crisis). The results were particularly sensitive to the price of imatinib, improvements in quality of life, and the duration of haematological responses. We conclude that treatment of CML with imatinib confers considerably greater survival and quality of life than conventional treatments but at a cost

    <p>Abstract</p> <p>Background</p> <p>Trastuzumab has revolutionized the way we treat early Her2Neu-positive breast cancer, as it significantly improves disease-free and overall survival. Little is known about the societal costs and benefits of treatment with trastuzumab in the adjuvant setting in Southeast Asia.</p> <p>Methods</p> <p>Societal costs (benefits) were estimated as the sum of direct and indirect costs minus benefits in the base case. Direct costs were derived from 4 treatment centers in Singapore (2 private and 2 public, comprising 60-70% of all patients with cancer seen in the island-nation); indirect costs were assessed as the loss of productivity caused by the disease or treatment. Benefits to society were based on extra years of productivity, as measured by GNI per capita, resulting from the quality adjusted life-years (QALYs) saved with the use of trastuzumab as determined in the models by Kurian, Liberato and Garrison.</p> <p>Results</p> <p>Incremental costs in Singapore, in 2005 US dollars, were 26,971.05.AverageCostperQALYwas26,971.05. Average Cost per QALY was 19,174.59 (Median: 18,993.70).Costs(benefits)tosocietyrangedfromacostof18,993.70). Costs (benefits) to society ranged from a cost of 79.42 to a benefit of 9,263.06,dependingonthemodelused(Averagebenefit:9,263.06, depending on the model used (Average benefit: 4,375.89, Median 3,944.03).Sensitivityanalysisrangedfromacostof3,944.03). Sensitivity analysis ranged from a cost of 10,685.00 to a Benefit of US$17,298.79</p> <p>Conclusions</p> <p>Treatment with adjuvant trastuzumab is likely to generate net societal economic benefits in Singapore. Nevertheless, the lower range of possible outcomes does not refute the possibility that treatment may actually generate costs. These costs however clearly fall within the usual range of acceptable cost-effectiveness.</p

    BACKGROUND: self-expanding metal stents are currently being used as a definitive palliative treatment for malignant colorectal obstruction in patients with incurable disease. Few studies have followed large numbers of patients from stent placement until death, and those few have reported conflicting results in the long-term clinical outcome data. AIMS: this study evaluated the clinical effectiveness of stent placement for malignant colorectal obstruction throughout the patients lives and related factors affecting stent patency, clinical success and complications. METHODS: this was a multicentre, retrospective study of 89 consecutive patients who had undergone attempted expandable stent placement for symptomatic malignant colorectal obstruction during a 10-year period. Data were collected to analyse the sustained relief of obstructive symptoms throughout the patients lives, as well as the technical success, immediate clinical success, stent patency, complications, reinterventions, survival, prognostic factors associated with stent patency and long-term clinical efficacy and risk factors for complications. RESULTS: technical and immediate clinical success were achieved in 95.5% and 91.0% of patients, respectively. A total of 68 out of 89 patients (76.4%) maintained relief of obstruction from stent implantation until death without reintervention. Twenty patients (22.5%) had complications including perforation (n = 4; 4.5%), stent obstruction (n = 8; 9.0%), migration (n = 5; 5.6%) and haemorrhage (n = 3; 3.4%). Stent-related mortality was seen in 1 patient (1.1%). The estimated median survival and estimated mean stent patency were 87.0 and 322.7 days, respectively. In total, 12 of the initial 89 patients (13.5%) needed a colostomy for long-term relief of the obstructive symptoms. Univariate and multivariate analysis detected no significant prognostic factors associated with stent patency, long term clinical efficacy and risk factors for complications; however, the multivariate logistic model revealed a non-significant trend by which the use of chemotherapy was a risk factor for migration (OR = 11.89; p = 0.06). CONCLUSIONS: for palliation of incurable malignant colorectal obstruction, expandable stents can provide sustained relief of obstruction in approximately 75% of patients. The procedure is associated with acceptable morbidity, need for reintervention and minimal mortality
