El cuidado como cuestión de tiempo: una perspectiva feminista sobre el tiempo cotidiano de cuidadoras de personas adultas con discapacidad / Caregiving as a matter of time: A feminist perspective of the daily time of women caregivers of adults with disabilities / O cuidado como questão de tempo: uma perspectiva feminista sobre o tempo cotidiano de mulheres cuidadoras de pessoas adultas com deficiência

El artículo aborda el carácter histórico y político del tiempo, por considerarle un articulador de la existencia humana, a partir de una lectura crítica de la vida cotidiana. La reproducción de la temporalidad está mediada por el trabajo, el que, analizado desde una perspectiva feminista-marxista, permite reconocer desigualdades en la experiencia del tiempo de hombres y mujeres, basadas en la división sexual del trabajo. Para profundizar en este fenómeno se presentan resultados derivados de una investigación cualitativa que buscó analizar la experiencia del tiempo cotidiano de mujeres que realizan el trabajo de cuidados de personas adultas con discapacidad en Santiago de Chile. Se realizaron entrevistas semiestructuradas y observaciones participantes en los contextos cotidianos de ocho mujeres, reconociendo que su experiencia del tiempo depende de otras personas, que está densificada por la continua realización simultánea de trabajos no remunerados y que no distingue tiempos libres, de ocio ni por fuera del cuidado. Se concluye reconociendo que las desigualdades de género también producen desigualdades en la experiencia del tiempo, lo que insta a avanzar en políticas sociales que reconozcan el cuidado como un derecho social para que las mujeres puedan construir experiencias de sentido, azar, demora y libertad.

The article addresses time's historical and political character, considering it an articulator of human existence from a critical reading of everyday life. The reproduction of temporality is mediated by work, which, analyzed from a feminist-Marxist perspective, allows the recognition of inequalities in the experience of time for men and women based on the sexual division of labor. To delve into this phenomenon, the article presents the results from qualitative research that sought to analyze the daily experience of women who are caregivers of adults with disabilities in Santiago de Chile. Methodologically, semi-structured interviews and participant observations were made in the everyday contexts of eight women, recognizing that their experience of time depends on other people, that it is densified by the continuous and simultaneous performance of unpaid work, and that it does not distinguish free time, leisure, or time outside care. It concludes by recognizing that gender inequalities also produce inequalities in the experience of time, which urges progress in social policies recognizing care as a social right so that women can build experiences of meaning, chance, delay, and freedom.

Time efficiency and operator convenience of using a micro-screw in image registration for guided implant surgery / 대한치과보철학회지

PURPOSE: The image registration of radiographic image and digital surface data is essential in the computer-guided implant guide system. The purpose of this study was to examine the effects of using micro-screw on the working time and convenience of operators in the process of image matching for guided implant surgery. MATERIALS AND METHODS: A mandibular dental model was prepared in partial edentulism for Kennedy class I classification. Two micro-screws were placed on the each side of retromolar area. Radiographic and scan images were taken using computed-tomography and digital scanning. The images were superimposed by 12 operators in software in two different conditions: using remaining teeth image alone and using teeth and micro-screws images. Working time, operator convenience and satisfaction were obtained, and analyzed using the Mann-Whitney U test (α=.05). RESULTS: The working time was not statistically different between image registration conditions (P>.05); however, operator convenience and satisfaction were higher in the teeth and micro-screw assisted condition than in the teeth-alone assisted condition (P<.001). CONCLUSION: The use of microscrew for the image registration has no effect in working time reduction, but improves operator convenience and satisfaction.

Effect of working time on the film thickness of dental resin cements / 대한치과보철학회지

PURPOSE: The aim of this study was to compare the film thicknesses of several resin cements as a function of time after mixing and to examine the effect of working time on the film thicknesses. MATERIALS AND METHODS: The film thickness (microm) of 4 resin cements (n=10), 1 composite resin (Panavia F 2.0), 3 self-adhesive resin (Clearfil SA luting, Zirconite, RelyX U200) cements was measured at 20-second intervals after mixing of the cements up to 200 seconds under a load of 50 N. Linear regression was fitted to verify the effect of working time on the film thickness of each cement. Data were compared to the working time recommended by manufacturers using Wilcoxon test (alpha=.05). RESULTS: All of the materials showed a positive linear correlation between the film thickness and working time. There was no statistically significant difference between the working time based on our results and the values recommended by the manufacturers even though there was a discrepancy between those two values. CONCLUSION: The film thickness of resin cements could increase with the increase of working time. Working time to meet the ISO standard of 50-microm maximum film thickness could be different from the manufacturer's recommended value.

Jornadas de trabalho na enfermagem: entre necessidades individuais e condições de trabalho / Nursing work hours: individual needs versus working conditions / Jornadas de trabajo en la enfermería: entre necesidades individuales y condiciones de trabajo

OBJETIVO: Analisar fatores associados à jornada de trabalho profissional e à jornada de trabalho total (profissional + doméstica) em profissionais de enfermagem. MÉTODOS: Estudo transversal realizado em hospital universitário no município de São Paulo, SP, entre 2004 e 2005. Participaram 696 trabalhadores (enfermeiros, técnicos e auxiliares de enfermagem), predominantemente mulheres (87,8 por cento), que trabalhavam em turnos diurnos e/ou noturnos. Foi aplicado questionário autopreenchível sobre dados sociodemográficos, condições de trabalho e de vida; e versões traduzidas e adaptadas para o português das escalas de demanda-controle-apoio social no trabalho, de desequilíbrio esforço-recompensa, do Questionário Genérico de Avaliação de Qualidade de Vida e do Índice de Capacidade para o Trabalho. Foram utilizados modelos de regressão logística para a análise dos dados. RESULTADOS: Ser o único responsável pela renda familiar, o trabalho noturno e o desequilíbrio esforço-recompensa foram as únicas variáveis associadas tanto à jornada profissional (OR = 3,38; OR = 10,43; OR = 2,07, respectivamente) quanto à jornada total (OR = 1,57; OR = 3,37; OR = 2,75, respectivamente). Nenhuma das variáveis ligadas às jornadas de trabalho se associou significativamente ao baixo Índice de Capacidade para o Trabalho. O tempo insuficiente para o repouso se mostrou estatisticamente associado às jornadas profissional (OR = 2,47) e total (OR = 1,48). O tempo insuficiente para o lazer se mostrou significativamente associado à jornada profissional (OR = 1,58) e valor limítrofe para a jornada total (OR = 1,43). CONCLUSÕES: A responsabilidade financeira, o trabalho noturno e o desequilíbrio esforço-recompensa são variáveis que merecem ser contempladas em estudos sobre as jornadas de trabalho em equipes de enfermagem. Sugere-se que estudos sobre o tema abordem a renda individual do trabalhador, detalhando melhor a relação entre os esforços e recompensas, e principalmente discussões que considerem as relações de gênero.

OBJECTIVE: To assess factors associated with professional and total hours of work (work + home) among nursing staff. METHODS: Cross-sectional study conducted in a university hospital in the city of São Paulo, southeastern Brazil, between 2004 and 2005. A total of 696 workers (nurses, nurse technicians and aids), mostly women (87.8 percent) working day and/or night shifts, participated in the study. A self-administered questionnaire was used to collected information on demographic characteristics, and working and life conditions. Translated and adapted into Portuguese versions of the Job Stress Scale, Effort-reward imbalance, Short-Form-Health-related quality of life and the Work Ability Index were also administered. Logistic regression models were used for data analysis. RESULTS: Sole breadwinner, working night shifts and effort-reward imbalance were the variables associated with both professional (OR = 3.38, OR = 10.43, OR = 2.07, respectively) and total hours of work (OR = 1.57, OR = 3.37, OR = 2.75, respectively). There was no significant association between the variables related to hours of work and low Work Ability Index. Inadequate rest at home was statistically associated with professional (OR = 2.47) and total hours of work (OR = 1.48). Inadequate leisure time was significantly associated with professional hours of work (OR = 1.58) and barely associated with total hours of work (OR = 1.43). CONCLUSIONS: The sole breadwinner, working night shifts and effort-reward imbalance are variables that need to be further investigated in studies on work hours among nursing staff. These studies should explore workers' income and the relationship between effort and reward, taking into consideration gender issues.

Participação nos lucros ou resultados e banco de horas: intensidade do trabalho e desgaste operário / Profit sharing and flexible working hours: intense workload and workers wearing down

Introdução: As transformações operadas no processo de trabalho na indústria automobilística no Brasil desde os anos 1990 apontam para o fortalecimento da gestão da força de trabalho como um dos determinantes do processo saúde-doença dos trabalhadores. Objetivos: Discutem-se dois elementos da gestão: a participação nos lucros ou resultados (PLR) e o banco de horas (BH) e assinala-se a relação de ambos com a intensidade do trabalho e o desgaste operário. Métodos: Apóia-se em revisão bibliográfica e em análise dos acordos coletivos dos metalúrgicos do ABC--SP, entre 2001 e 2008. Resultados: A análise realizada mostrou que a reorganização do tempo de trabalho, o prolongamento da jornada e a manutenção do elevado grau de intensidade do trabalho ocasionados pelo BH e as metas vinculadas à PLR exercem pressão sobre o trabalhador para o aumento quantitativo e qualitativo do trabalho, evidenciando que esses instrumentos gerenciais propiciam a intensificação do trabalho e o desgaste operário. Também afetam drasticamente o tempo de não trabalho fora da jornada, inclusive prejudicando a reposição e o desenvolvimento da capacidade biopsíquica do trabalhador. Conclusão: A PLR e o BH podem ser caracterizados como uma forma de administração por estresse que eleva e potencializa as cargas de trabalho e o desgaste operário.

Introduction: Changes introduced in Brazilian automotive industry working process since the 1990s have increased the weight of workforce management as determinant of workers health. Background: This article discusses two elements of management: profit or result sharing (PRS) and flexible working hours (FWH), drawing attention to the relationship between these two aspects and work intensity as well as workers wearing down. Method: Literature review and analysis of collective agreements negotiated by the metal workers union in ABC-SP (SantoAndre, São Bernardo and São Caetano three industrial centers in São Paulo metropolitan area), between 2001 and 2008. Results: The analysis showed that reorganization and lengthening of working time as well as high work intensity, both resulting from PRS goal achievement process and FWH, push workers towards qualitative and quantitative increase of their work, evidencing that these managerial tools cause work intensification and workers wearing down. Time off work is also affected, hindering workers recovery and biopsychic abilitydevelopment as well. Conclusion: PRS and FWH can be characterized as models of management by stress, which increase workload and workers wearing down.

Efeito do protocolo de ativação da polimerização e envelhecimento acelerado em algumas propriedades de cimentos resinosos / Effects of polymerization activation protocol and accelerated aging in some resin cements properties

Este estudo teve como objetivo avaliar os efeitos de variações no protocolo de ativação e envelhecimento acelerado em algumas propriedades de cimentos resinosos de polimerização dual. Adicionalmente, investigaram-se os efeitos da variação da temperatura ambiente e envelhecimento acelerado no tempo de trabalho e tempo de presa dos cimentos quando ativados exclusivamente pela reação química. As propriedades avaliadas foram o grau de conversão, determinado por espectrometria no infravermelho com transformada de Fourier (FTIR-ATR), microdureza Knoop, expressa em KHN, e resistência mecânica à tração expressa em MPa. Os tempos de trabalho e tempos de presa foram determinados por um reômetro oscilatório com controle de temperatura da plataforma de teste estabelecida em 24oC ou 37oC. O envelhecimento acelerado foi determinado pela armazenagem dos cimentos, em suas embalagens originais, e após os testes iniciais, em estufa a 37oC por 12 semanas.A variável de modo de ativação foi determinada em 3 níveis. Os cimentos foram manipulados de acordo com as instruções dos fabricantes e ativados por luz imediatamente (controle), ativados por luz após 10 minutos de reação química no escuro (Exp 1) ou mantidos no escuro por 15 minutos, permitindo a reação química, mas sem fotoativação (Exp 2). Os cimentos tiveram suas propriedades avaliadas em função desses diferentes modos de ativação, antes e após o envelhecimento acelerado. Cimento exclusivamente ativado pela reação química foi empregado como controle quando necessário. Os diversos resultados podem ser resumidos em alguns aspectos de interesse. O tempo de trabalho e o tempo de presa de todos cimentos foram afetados significantemente pela temperatura e envelhecimento (p<0.05). O aumento da temperatura acelerou os tempos de trabalho e presa. Os efeitos do envelhecimento foram materiaisdependentes. Alguns materiais apresentaram redução, enquanto outros apresentaram aumento dos tempos de trabalho e presa, independentemente da...

The study aimed to evaluate the effects of curing protocol and accelerated aging on some properties of dual-cure resin cements. Additionally, the effects of different ambient temperature and aging on the working and setting times were investigated when cements were self-cured only. Properties evaluated were degree of conversion as determined by FTIR-ATR spectroscopy, Knoop microhadness as expressed by KHN, and tensile strength as expressed in MPa. Working time and setting time were determined by an oscilating rheometer with controlled temperature stage at either 24oC or 37oC. Accelerated aging was performed by storing the original product kits in an oven at 37oC for 12 weeks after initial testing had been executed. Different curing protocols were established in 3 levels. Cements were manipulated according to the manufacturers instructions and light-activated immediately (control), light-activated after 10 minutes delay of self-curing in the dark (Exp 1), or simply allowed to self-cure for 15 minutes in the dark (Exp 2). Properties were evaluated according to the different curing protocol and both before and after aging. Exclusively self-curing cement was used as control product when appropriate. The results can be summarized in some aspects of interest. The working time and setting time of all products were significantly affected by temperature and aging (p<0.05). Increased temperature resulted in shorter working time and setting time. The effects of aging were material dependent. Some products presented reduced working and setting times, while others behave otherwise, regardless of the temperature. Curing mode and aging significantly affected the properties of the cements (p<0.05). In general, the degree of conversion increased with time after light-activation. The curing delay for 10 minutes caused alterations in the degree of conversion, regardless of aging, for some products, but not all. Aging affected the curing kinectics and general properties of all...

A study on the material properties of various composite resins for core build-up / 대한치과보존학회지

The purposes of this study were to estimate the material properties of the recently developed domestic composite resins for core filling material (Chemical, Dual A, Dual B; Vericom, Korea) and to compare them with other marketed foreign products (CorePaste, Den-Mat, USA; Ti-Core, Essential Dental Systems, USA; Support, SCI-Pharm, USA). Six assessments were made; working time, setting time, depth of polymerization, flexural strength, bonding strength, and marginal leakage. All items were compared to ISO standards. All domestic products satisfied the minimum requirements from ISO standards (working time: above 90 seconds, setting time: within 5 minutes), and showed significantly higher flexural strength than Core Paste. Dual A and B could, especially, reduce the setting time to 60 seconds when cured with 600 mW/cm2 light intensity. All experimental materials showed 6 mm depth of polymerization. Bond strengths of Ti-Core and Dual B materials were significantly higher than the other materials. Furthermore, three domestic products and Ti-Core could reduce the microleakage effectively.
