Indicadores de gestão em cuidados intensivos

As unidades de cuidados intensivos (UCI), são das áreas hospitalares que mais dinheiro consomem nas instituições públicas. As funções dos profissionais de saúde são imprescindíveis, mas também a logística e gestão são de vital importância e como tal, têm de ser avaliadas. Por isso, todos os indicadores – clínicos, económico-financeiros, recursos humanos, produtividade, qualidade - são importantes para que a gestão possa, dinâmica e oportunamente, ter informação útil para a tomada de decisões. Assim, a garantia de uma gestão eficiente dos recursos é cada vez mais importante de forma a satisfazer não só os pacientes como toda a estrutura hospitalar. Nos tempos que correm, e com a situação socioeconómica de crise que se vive, é de extrema importância saber com o maior nível de detalhe possível, com que recursos se pode contar. É importante quantificar de forma eficaz e eficiente como são utilizados os recursos, para satisfazer com o maior nível de qualidade possível um paciente que entre numa UCI. Para tal, a utilização de sistemas de informação (SI) e das ferramentas indicadas na gestão de uma unidade hospitalar, são de grande importância. Nesta tese, é proposta uma ferramenta, que seja simples e de fácil utilização, desenvolvida com recurso a tecnologia ROLAP para a extracção e análise de indicadores numa UCI, e que possa ser facilmente integrada num software de gestão do dia-a-dia.

Aplicação da filosofia Lean para melhoria do processo numa linha de produção da empresa IKEA

Devido à atual crise socioeconómica e consequente recessão dos mercados, as empresas precisam cada vez mais de melhorar os seus modelos de gestão e apostar na melhoria dos seus processos de forma a conseguirem produzir produtos de qualidade utilizando o menor custo de produção possível. O uso das ferramentas Lean Production e das ferramentas de Gestão da Qualidade permite às empresas reduzir, ou até mesmo eliminar alguns desperdícios. Desta forma é possível reduzir custos de produção e aumentar a produtividade. Neste contexto surge a presente dissertação, realizada na empresa IKEA Industry Portugal no âmbito do Mestrado em Engenharia Mecânica – Gestão Industrial, que tem como principal objetivo melhorar o processo produtivo de uma linha de produção da área EdgeBand & Drill, linha Biesse. No início deste projeto esta linha apresentava uma eficiência de 45,83%. Depois da descrição da empresa e do seu funcionamento, realizou-se um estudo sobre o estado atual do sistema produtivo da área de produção em estudo, Edgeband & Drill, mais concretamente da linha Biesse. Desse estudo resultou a identificação de alguns problemas da linha, nomeadamente a baixa eficiência, elevados tempos de paragem da linha, elevada quantidade de peças com defeitos, elevados custos associados a peças sucata, falta de polivalência dos operadores, desperdícios de matérias primas e falta de organização e limpeza da área. Depois de identificados os problemas foram apresentadas algumas propostas de melhoria para o processo produtivo da linha Biesse. Nesta fase foram utilizadas algumas ferramentas Lean e de Gestão da Qualidade. No fim do projeto obteve-se uma redução de 1,26% dos tempos de paragem, uma redução de 1317 peças com defeito e uma poupança de 1147,44€ em peças sucata. Estes valores contribuíram para uma melhoria da eficiência global em cerca de 1,06% para a área EdgeBand & Drill e uma melhoria de 3,11% para a linha em estudo, linha Biesse.

Food consumption, physical activity and socio-economic status related to BMI, waist circumference and waist-to-height ratio in adolescents

Objective: To examine the association between obesity and food group intakes, physical activity and socio-economic status in adolescents. Design: A cross-sectional study was carried out in 2008. Cole’s cut-off points were used to categorize BMI. Abdominal obesity was defined by a waist circumference at or above the 90th percentile, as well as a waist-to-height ratio at or above 0?500. Diet was evaluated using an FFQ, and the food group consumption was categorized using sex-specific tertiles of each food group amount. Physical activity was assessed via a self-report questionnaire. Socio-economic status was assessed referring to parental education and employment status. Data were analysed separately for girls and boys and the associations among food consumption, physical activity, socio-economic status and BMI, waist circumference and waist-to-height ratio were evaluated using logistic regression analysis, adjusting the results for potential confounders. Setting: Public schools in the Azorean Archipelago, Portugal. Subjects: Adolescents (n 1209) aged 15–18 years. Results: After adjustment, in boys, higher intake of ready-to-eat cereals was a negative predictor while vegetables were a positive predictor of overweight/ obesity and abdominal obesity. Active boys had lower odds of abdominal obesity compared with inactive boys. Boys whose mother showed a low education level had higher odds of abdominal obesity compared with boys whose mother presented a high education level. Concerning girls, higher intake of sweets and pastries was a negative predictor of overweight/obesity and abdominal obesity. Girls in tertile 2 of milk intake had lower odds of abdominal obesity than those in tertile 1. Girls whose father had no relationship with employment displayed higher odds of abdominal obesity compared with girls whose father had high employment status. Conclusions: We have found that different measures of obesity have distinct associations with food group intakes, physical activity and socio-economic status.

Legal and political regulation of higher education in Portugal: an evolutionary perspective on the current policy issues and the problem of order

The higher education system in Europe is currently under stress and the debates over its reform and future are gaining momentum. Now that, for most countries, we are in a time for change, in the overall society and the whole education system, the legal and political dimensions have gained prominence, which has not been followed by a more integrative approach of the problem of order, its reform and the issue of regulation, beyond the typical static and classical cost-benefit analyses. The two classical approaches for studying (and for designing the policy measures of) the problem of the reform of the higher education system - the cost-benefit analysis and the legal scholarship description - have to be integrated. This is the argument of our paper that the very integration of economic and legal approaches, what Warren Samuels called the legal-economic nexus, is meaningful and necessary, especially if we want to address the problem of order (as formulated by Joseph Spengler) and the overall regulation of the system. On the one hand, and without neglecting the interest and insights gained from the cost-benefit analysis, or other approaches of value for money assessment, we will focus our study on the legal, social and political aspects of the regulation of the higher education system and its reform in Portugal. On the other hand, the economic and financial problems have to be taken into account, but in a more inclusive way with regard to the indirect and other socio-economic costs not contemplated in traditional or standard assessments of policies for the tertiary education sector. In the first section of the paper, we will discuss the theoretical and conceptual underpinning of our analysis, focusing on the evolutionary approach, the role of critical institutions, the legal-economic nexus and the problem of order. All these elements are related to the institutional tradition, from Veblen and Commons to Spengler and Samuels. The second section states the problem of regulation in the higher education system and the issue of policy formulation for tackling the problem. The current situation is clearly one of crisis with the expansion of the cohorts of young students coming to an end and the recurrent scandals in private institutions. In the last decade, after a protracted period of extension or expansion of the system, i. e., the continuous growth of students, universities and other institutions are competing harder to gain students and have seen their financial situation at risk. It seems that we are entering a period of radical uncertainty, higher competition and a new configuration that is slowly building up is the growth in intensity, which means upgrading the quality of the higher learning and getting more involvement in vocational training and life-long learning. With this change, and along with other deep ones in the Portuguese society and economy, the current regulation has shown signs of maladjustment. The third section consists of our conclusions on the current issue of regulation and policy challenge. First, we underline the importance of an evolutionary approach to a process of change that is essentially dynamic. A special attention will be given to the issues related to an evolutionary construe of policy analysis and formulation. Second, the integration of law and economics, through the notion of legal economic nexus, allows us to better define the issues of regulation and the concrete problems that the universities are facing. One aspect is the instability of the political measures regarding the public administration and on which the higher education system depends financially, legally and institutionally, to say the least. A corollary is the lack of clear strategy in the policy reforms. Third, our research criticizes several studies, such as the one made by the OECD in late 2006 for the Ministry of Science, Technology and Higher Education, for being too static and neglecting fundamental aspects of regulation such as the logic of actors, groups and organizations who are major players in the system. Finally, simply changing the legal rules will not necessary per se change the behaviors that the authorities want to change. By this, we mean that it is not only remiss of the policy maker to ignore some of the critical issues of regulation, namely the continuous non-respect by academic management and administrative bodies of universities of the legal rules that were once promulgated. Changing the rules does not change the problem, especially without the necessary debates form the different relevant quarters that make up the higher education system. The issues of social interaction remain as intact. Our treatment of the matter will be organized in the following way. In the first section, the theoretical principles are developed in order to be able to study more adequately the higher education transformation with a modest evolutionary theory and a legal and economic nexus of the interactions of the system and the policy challenges. After describing, in the second section, the recent evolution and current working of the higher education in Portugal, we will analyze the legal framework and the current regulatory practices and problems in light of the theoretical framework adopted. We will end with some conclusions on the current problems of regulation and the policy measures that are discusses in recent years.

Identifying economic periods and crisis with the multidimensional scaling

This paper applied MDS and Fourier transform to analyze different periods of the business cycle. With such purpose, four important stock market indexes (Dow Jones, Nasdaq, NYSE, S&P500) were studied over time. The analysis under the lens of the Fourier transform showed that the indexes have characteristics similar to those of fractional noise. By the other side, the analysis under the MDS lens identified patterns in the stock markets specific to each economic expansion period. Although the identification of patterns characteristic to each expansion period is interesting to practitioners (even if only in a posteriori fashion), further research should explore the meaning of such regularities and target to find a method to estimate future crisis.
