This paper describes a quantitative similarity metric and its contribution to achieve original plan solutions. This similarity metric is used by an iterative process of piece retrieval from structured plan cases. Within our approach plan cases are tree-like networks of pieces (goals and actions). These case pieces are ill-related each other by links (explanations). These links may be classified as hierarchical or temporal, antecedent or consequent, and explicit or implicit. Besides links, each case piece has also information about its properties (the attributes-value pairs), its hierarchical and temporal position in the case (the address), and about its constraints in the relationship with others (the constraints). The similarity metric computes a similarity value between two case pieces taking into account similarities between these case piece’s information types. Each time a problem is proposed, different weights are given to some of those similarities, with the aim of solving it with an original solution. This similarity metric is used by the system INSPIRER (ImagiNation taking as Source Past and Imperfectly REalated Reasonings). We illustrate the role of the similarity metric in the creativity of solutions, focusing specially their originality...

O objetivo geral deste trabalho foi de examinar os critérios e condições do plano de participação nos lucros e nos resultados (PPLR) adotado nas indústrias visando ao seu conhecimento para posterior investigação da sua inserção no controle gerencial. A realização deste trabalho deu-se por meio do estudo de casos em quatro indústrias. Para alcançar o objetivo geral foi necessário identificar nas empresas: aspectos que caracterizam os planos de recompensa objetivando o conhecimento dos critérios e condições definidos para o funcionamento do plano, com o intuito subliminar de estudar-se a percepção que as partes (superiores e subordinados) têm do plano. Dentre os casos estudados, dois apresentaram o PPLR inserido no controle de gestão, os demais apresentaram uma inserção parcial. Foram identificados também os fatores relevantes à continuidade da empresa, verificando se há relação entre indicadores do plano de recompensa e esses fatores. De forma geral, o estudo dos casos sugeriu que as empresas estudadas confiam na capacidade motivacional de uma gratificação financeira adicional, além do salário e 13º salário, pois a praticam. Entretanto, a formulação de um plano de recompensa financeira baseada no desempenho parece não ter sido uma prática totalmente espontânea nas empresas. Sua implantação decorre parcialmente de pressões sociais e da regulamentação do PPLR...

O desempenho do setor de saúde suplementar no Brasil tem se caracterizado pela cobertura de eventos curativos e crescimento das despesas assistenciais. Apresenta-se o perfil de 353 consumidores (2,3% do total) responsáveis por R$ 6,87 milhões (35%) dos gastos com despesas assistenciais da unidade administrativa de Porto Alegre – RS de uma operadora de medicina de grupo, durante cinco anos (01/1999 a 12/2003). Estes gastos foram analisados por sexo, faixa etária e nosologia, e foram classificados por ordem decrescente de valor. Os dados usados nesta pesquisa foram obtidos dos sistemas de cadastro e faturamento da organização. Comprovou-se uma elevada participação nas despesas com clientes com 60 ou mais anos (30,95%) e com as doenças neoplásicas (29%) e cardiovasculares (20%). Ocorreram 67 casos de neoplasia (R$ 1,98 milhões) cujas maiores despesas foram por dois casos de Doença de Hodgkin (R$ 307,5 mil) e dois outros por Leucemia (R$ 209,2 mil). Logo após, nesta ordem, nove beneficiárias (idade média 50 anos), com câncer de mama, geraram um gasto de R$ 167 mil. Apesar de, até o presente, se desconhecer estratégias preventivas eficazes para as duas primeiras colocações entre as neoplasias, os casos de câncer de mama permitiriam uma atuação intensa neste sentido. A doença isquêmica do coração acometeu o maior número dentre os beneficiários (27 casos) gerando um gasto de R$ 544...

OBJECTIVE--To investigate the numbers of visits required to obtain interviews with users and non-users of cervical screening, and to determine the workload involved to enable an optimum visit plan to be developed. DESIGN--Case-control study of users and non-users of cervical screening using a flexible visit plan that involved up to eight attempts at contact. Visits were made in mornings, afternoons, and evenings, the visit pattern being determined by information gained from local sources. PATIENTS--Altogether 660 non-users of cervical screening (cases), aged 20-64 and registered with 23 randomly selected general practitioners (GPs), were identified from the Tayside computerised register of cervical smears. These women were selected from the computerised lists of 18 GPs in Dundee and five in Perth. A total of 417 women recorded as having a smear within the previous three years (controls), matched by age and GP, were also identified from the computerised register. RESULTS--Altogether 1834 attempts were made to contact the cases, of whom 339 were interviewed, giving a workload of 18 interviews per 100 attempts. For the controls 1359 attempts were made at contact to yield 339 interviews, a workload of 25 interviews per 100 attempts. Refusals (19%) and incorrect addresses (23%) were the two major reasons for failing to achieve interview. Only for four (0.6%) of the cases and one (0.2%) of the controls was no information gained. The proportion of attempts which led to interview remained constant with increasing numbers of call-backs (up to six for the cases and eight for the controls). CONCLUSIONS--A flexible approach to visit scheduling that takes account of local knowledge can lead to interviews with 66% of non-users of health screening...

To develop an easy independent patient-specific quality assurance (QA) method using a benchmark plan for high-dose-rate intracavitary brachytherapy for cervix cancer, we conducted benchmark treatment planning with various sizes and combinations of tandem-ovoid and tandem-cylinder applications with ‘ideal’ geometry outside the patient. Two-dimensional-based treatment planning was conducted based on the Manchester method. We predicted the total dwell time of individual treatment plans from the air kerma strength, total dwell time and prescription dose of the benchmark plan. In addition, we recorded the height (dh), width (dw) and thickness (dt) covered with 100% isodose line. These parameters were compared with 169 and 29 clinical cases for tandem-ovoid or tandem-cylinder cases, respectively. With regard to tandem-ovoid cases, differences in total dwell time, dh, dt and dw between benchmark and individual plans were on average –0.2% ± 3.8%, –1.0 mm ± 2.6 mm, 0.8 mm ± 1.3 mm and –0.1 mm ± 1.5 mm, respectively. With regard to tandem-cylinder cases, differences in total dwell time, dhfront (the distance from tandem tip to tandem ring), dt and dw between benchmark and individual plans were on average –1.5% ± 3.1%...

The purpose of this study was to develop a computer-aided method for determination of beam arrangements based on similar cases in a radiotherapy treatment-planning database for stereotactic lung radiation therapy. Similar-case-based beam arrangements were automatically determined based on the following two steps. First, the five most similar cases were searched, based on geometrical features related to the location, size and shape of the planning target volume, lung and spinal cord. Second, five beam arrangements of an objective case were automatically determined by registering five similar cases with the objective case, with respect to lung regions, by means of a linear registration technique. For evaluation of the beam arrangements five treatment plans were manually created by applying the beam arrangements determined in the second step to the objective case. The most usable beam arrangement was selected by sorting the five treatment plans based on eight plan evaluation indices, including the D95, mean lung dose and spinal cord maximum dose. We applied the proposed method to 10 test cases, by using an RTP database of 81 cases with lung cancer, and compared the eight plan evaluation indices between the original treatment plan and the corresponding most usable similar-case-based treatment plan. As a result...

En 2007, le Collège des médecins du Québec a résolu d’adopter le plan d’autogestion du développement professionnel continu (DPC) comme outil de maintien de la compétence professionnelle. Bien que la plupart des médecins reconnaissent la nécessité de demeurer à la fine pointe des connaissances et des découvertes médicales, certains considèrent le plan d’autogestion comme une corvée administrative. Afin de mieux comprendre leurs perceptions à l’égard du plan de DPC, une recherche qualitative a été menée à l’été 2010, par le biais d’entretiens individuels semi-structurés, auprès d’un échantillon de vingt-sept médecins québécois. Un échantillonnage mixte, utilisant la technique « boule de neige » et faisant appel à des informateurs clés et à des cas dits « négatifs », a permis d’atteindre un bon niveau de diversification de l’échantillon et la saturation empirique des données. Bien que les médecins interrogés soient généralement favorables au principe d’un plan d’autogestion de DPC, les commentaires et suggestions formulés par certains d’entre eux devraient inciter le Collège à apporter certaines améliorations à ce plan. Certains irritants tels que la nécessité de tenir à jour un registre des activités de DPC et d’en rendre compte au Collège ont été soulevés. Par contre...

Introducción y Justificación: La Enfermedad Pulmonar Obstructiva Crónica (EPOC) presenta un incremento de prevalencia y morbi-mortalidad, además se estima que será la tercera causa de muerte en el mundo y la quinta en años de vida perdidos con discapacidad. La EPOC presenta una importante carga asistencial, impacto sociosanitario y económico, deterioro de la calidad de vida y discapacidad. El actual modelo asistencial necesita una profunda revisión para incorporar elementos como educación sanitaria, rehabilitación, promoción del automanejo e implicación del paciente en la toma de decisiones. Los planes de automanejo están dirigidos a la enseñanza de habilidades para optimizar el control de la enfermedad, la carga asistencial y la calidad de vida. En la EPOC, el automanejo se ha estudiado menos que en otras enfermedades crónicas y los beneficios en la práctica general son todavía inconcluyentes. Objetivo: Valorar si un programa de automanejo en pacientes con EPOC frágiles, multicomponente y multidisciplinar reducía la tasa de exacerbaciones graves frente a los cuidados habituales. Material y métodos: Estudio prospectivo, multicéntrico, controlado, aleatorizado y ciego simple. Seguimiento de 12 meses. Se reclutaron pacientes mayores de 50 años diagnosticados de EPOC con al menos un ingreso hospitalario o atención en urgencias por agudización en el año previo. Se excluyeron pacientes con deterioro cognitivo y físico avanzado...

Durante o século XIX, para financiar a atividade econômica, era comum as jovens nações captarem empréstimos no exterior com pagamento em moeda estrangeira. A prática, chamada de Pecado Original era comum no regime do padrão ouro e objetivava garantir aos credores segurança num mercado financeiro ainda em desenvolvimento, que não oferecia instrumentos de proteção contra a flutuação de moedas não lastreadas e para casos de mercado secundário pouco desenvolvido no país devedor. A prática de fornecer empréstimos com serviço em moeda estrangeira perdura pelo século XX com notável estabilidade, haja vista a retomada do sistema de câmbio fixo (Padrão Dólar-Ouro) durante o Fordismo. Neste período, protegidos pela estabilidade cambial, os países em desenvolvimento fizeram uso da prática de rolagem da dívida para cumprir suas obrigações e obter recursos para custear o crescimento de suas economias. O Brasil foi um bom exemplo desta prática. A crise da década de 1970, porém, põe fim ao regime de câmbio fixo. Com a flutuação das moedas estrangeiras, as taxas de juros internacionais tornam-se mais voláteis, colocando em risco todos os países em desenvolvimento que fizeram uso da estratégia de rolagem da dívida nas décadas anteriores. Em 1979...

Traballo fin de grao (UDC.ENFC). Enfermaría. Curso 2014/2015.; [Resumen] Introducción: Las UPP son complicaciones que se presentan en cualquier nivel de asistencia sanitaria. Su abordaje radica en la aplicación de unos cuidados adecuados para su prevención y tratamiento precoz en el caso de que aparezcan, evitando de esta manera la gravedad de sus complicaciones. La presencia de UPP afecta a la calidad de vida de los pacientes que las padecen, aumentando su mortalidad y el consumo de recursos sanitarios. Sabiendo que el 95% de las mismas son prevenibles con la aplicación de cuidados apropiados, su aparición se relaciona directamente con la calidad de los cuidados, por lo que será responsabilidad directa de los profesionales de enfermería su prevención, cuando estos sean los proveedores de cuidados. Las UCI son las unidades hospitalarias con la prevalencia de UPP más elevada, debido a la situación en la que se encuentran los pacientes ingresados en ellas. Por esto, la prevención de UPP, que incluya unos cuidados básicos esenciales, es el mejor método de abordaje de las mismas. Objetivo: Propuesta, aplicación y posterior evaluación, de un plan de cuidados estándar para la prevención de UPP en pacientes ingresados en una UCI de adultos. Desarrollo: Se realiza un plan de cuidados estandarizado que incluye los cuidados básicos para la prevención de UPP...

MBA Professional Report; Using a stakeholder management approach, this thesis helps the U.S. Navy understand who the external stakeholders are with respect to the Thirty-Year Shipbuilding Plan, the priority of differing stakeholder claims, and the nature of the U.S shipbuilding industry, one key stakeholder group. By citing the over-arching goals of the Navy's shipbuilding plan, reviewing Congressional testimony and reports on this plan, and financial analysis of individual shipbuilding firms, this thesis discerns key facets that explain shipbuilder behavior. To better manage shipbuilders, the Navy should develop strategies that refine shipbuilding business cases by stabilizing production rates, achieving greater design stability, and reducing order intervals.

This paper forms the action plan for financial consumer protection, and focuses on the main findings and recommendations. These include proposing specific actions to be undertaken by Latvian authorities, financial institutions and consumer organizations, so that consumer protection is strengthened and made more effective and efficient. Existing industry ombudsmen should publish cases they have dealt with, as well as their yearly activity report, which should be provided to the Financial and Capital Market Commission (FCMC), and to the Consumer Rights Protection Center (CRPC). The action plan draws on best international practices and experiences of regulators and supervisors, who have tried to introduce improved consumer protection regimes in their countries. A well balanced consumer protection regime serves the interest of financial institutions as it provides them with better-informed clients and makes sure that clients understand their obligations under the contracts they signed. The paper takes into account the current macroeconomic situation in Latvia...

Débat public, participation, délibération, autant de termes utilisés pour parler de normes et de dispositifs qui participeraient au nouvel « impératif délibératif » (Blondiaux et Sintomer 2002). Ce mémoire présente une analyse du débat public sur le plan d'urbanisme de Montréal avec un schéma d'analyse inspiré de celui de Simard et Fourniau (2007). Notre discussion du processus de débat porte non seulement sur la phase formelle des audiences publiques, mais aussi sur les étapes de concertation en amont et sur divers processus plus ou moins publicisés en aval. Ceci permet une réflexion d'ordre procédural plus riche qui considère la diversité des dispositifs dans une perspective de complémentarité. Pour chercher des effets du débat public sur le plan d'urbanisme, nous adoptons le parti de la congruence (Offner 1993), ce qui nous amène à une analyse de l'interaction entre des dynamiques contextuelles et des mobilisations des participants au débat. Certaines de ces congruences concordent avec des modifications au plan d'urbanisme. Notre étude propose aussi des implications du contexte particulier de la nouvelle ville de Montréal (avec la création des arrondissements) sur le contenu du débat public, sur certaines de ses manifestations procédurales ainsi que sur sa portée. Notre dernier chapitre montre que la dynamique du débat public en aval...

Designing cities is a complex proposition. Planners, architects and landscape architects all center their practice on aspects of this proposition. As such, their respective disciplines share the realm of urban design. This thesis attempts to understand how professionals from these three groups work as urban designers by testing the hypothesis that professional training and affiliation dictates distinct differences in how urban plans are developed by planners, architects or landscape architects. Relying on the American educational and professional associations for each discipline, the thesis proposes three spectra to contrast the disciplines: The Role of Process, Understanding of Physical Space, and Ultimate Goals. These spectra are applied to cases studies of Unified New Orleans Plan recovery plan development in three of New Orleans' 13 planning districts. The cases focus on the professional staff for each district, which include one planning firm, one architecture firm and one landscape architecture firm. The cases demonstrate predictive connections between planning training and concepts and the planning firm's performance and architecture training and concepts and the architecture firm's performance.; (cont.) There is less predictive evidence in the case of landscape architecture. The challenges of using a quasi-experimental design...

This paper describes a representation of plan cases as a structured set of goals and actions. These goals and actions are the unit pieces that form a case. These case pieces are related each other by hierarchical and temporal links (explanations) forming a tree-like network. We give importance not just to explicit links, i.e., links between case pieces which are concretely known, but also to implicit ones, i.e., possibly unknown links between case pieces. Each case piece is explained by antecedent links and explains other case pieces by consequent links. The retrieval of a case piece is mainly guided by its links and by its surrounding case pieces. Our concept of case piece usefulness is briefly explained. We discuss the benefit of reusing and directly accessing small case pieces from multiple cases for improving the Case-Based Reasoning (CBR) systems’ capability and efficiency to solve problems. We explain the importance of stepwise refinement in plan cases and also the role that temporal representation can take in the meaningful and coherent construction of planning problem solutions. An application in musical composition domain is presented. We also show how a musical composition task can be treated as a planning task.

VMAT optimization is a computationally challenging problem due to its large data size, high degrees of freedom, and many hardware constraints. High-performance graphics processing units have been used to speed up the computations. However, its small memory size cannot handle cases with a large dose-deposition coefficient (DDC) matrix. This paper is to report an implementation of our column-generation based VMAT algorithm on a multi-GPU platform to solve the memory limitation problem. The column-generation approach generates apertures sequentially by solving a pricing problem (PP) and a master problem (MP) iteratively. The DDC matrix is split into four sub-matrices according to beam angles, stored on four GPUs in compressed sparse row format. Computation of beamlet price is accomplished using multi-GPU. While the remaining steps of PP and MP problems are implemented on a single GPU due to their modest computational loads. A H&N patient case was used to validate our method. We compare our multi-GPU implementation with three single GPU implementation strategies: truncating DDC matrix (S1), repeatedly transferring DDC matrix between CPU and GPU (S2), and porting computations involving DDC matrix to CPU (S3). Two more H&N patient cases and three prostate cases were also used to demonstrate the advantages of our method. Our multi-GPU implementation can finish the optimization within ~1 minute for the H&N patient case. S1 leads to an inferior plan quality although its total time was 10 seconds shorter than the multi-GPU implementation. S2 and S3 yield same plan quality as the multi-GPU implementation but take ~4 minutes and ~6 minutes...

Habitat Conservation Plans (HCPs) are a means for private landowners to comply with the Endangered Species Act. Historically, the HCP process has been done on a case-by-case basis, but it has become increasingly common for county and regional governments to create region-wide HCPs that cover development from multiple projects in the entire region. Local governments recognize that these plans can increase economic certainty for residents, increase development, and potentially increase conservation. However, region-wide plans are time and money intensive, so sometimes they fail to be completed.

HCP legal, academic and policy experts, who acted as a focus group for this research, stated that few have studied the "human" side of HCP creation, i.e., HCP process design and management. Such information may be useful to diverse interests, such as conservationists and developers, in counties and regions where a large-scale HCP is possible. Thus, the overarching research question for this project was: What factors and processes lead to the successful completion of a Habitat Conservation Plan at the regional and county level?

This report includes five case studies on county or regional HCPs, located in 1) Benton County, OR; 2) Coachella Valley...
