Anthropometry has long been used for a range of ergonomic applications & product design. Although products are often designed for specific cohorts, anthropometric data are typically sourced from large scale surveys representative of the general population. Additionally, few data are available for emerging markets like China and India. This study measured 80 Chinese males that were representative of a specific cohort targeted for the design of a new product. Thirteen anthropometric measurements were recorded and compared to two large databases that represented a general population, a Chinese database and a Western database. Substantial differences were identified between the Chinese males measured in this study and both databases. The subjects were substantially taller, heavier and broader than subjects in the older Chinese database. However, they were still substantially smaller, lighter and thinner than Western males. Data from current Western anthropometric surveys are unlikely to accurately represent the target population for product designers and manufacturers in emerging markets like China.  相似文献

This paper focuses on the reality of very small and small enterprises (VSSEs) in Brazil, concerning health and safety management of their workers. These companies tend to operate in a few administrative levels. The owners' health and safety culture is fundamental for the implementation of preventive measures. The VSSEs end up adopting merely reactive and under-the-law actions. In order to understand such reality, a questionnaire was elaborated especially for the research made. Fifty-five very small and small enterprises of the industrial, commercial and service sectors were selected. The research confirmed the reactive attitude shown by the VSSEs, thus demonstrating that none of the companies involved presented policies of safety and health. Even though not holding policies, programs or scopes of their activities, 22% of them revealed to have a clear definition of the responsibilities of their high level administration. Nevertheless, 10% had financial resources allocated to this sector. Such companies do not count on a frequent safety and health support. The ignorance on it leads them to take a reactive action. This study reaches its objective on contributing to the debate, besides indicating that the way to improvement is on the strict cooperation between governments, companies, workers and society.  相似文献

This paper presents a comparative study of working conditions and health hazards of two ports in the state of Ceará: Mucuripe and Pecém, focusing workers in the various categories involved in the operational activities of the two ports. The aim is to investigate changes implemented by the restructuring process of ports arising from the Port Modernization Act. In the case of Ceará, the organization and control of work at the mentioned ports occur differently: Mucuripe, the oldest port, had to adapt to the changes enforced by the Modernization Act and Pecém, called Port Terminal, inaugurated in 2001, "was born modern". To achieve our objective, we carried out field work, using Ergonomic Work Analysis. Systematic observations were made of the various activities carried out by workers, as well as interviews with managers, workers and trade unionists. Container operations and other activities of the two ports were recorded in film and presented to groups of workers (focus groups) in order to better understand work organization and the main differences in tasks carried out in the two ports. Each reality presents different characteristics regarding port operations, type of work and labor control. Results indicate that due to the technological innovations, the restructuring process reduced some risks, but brought new occupational hazards and intensification of work.  相似文献

Seat pressure is known as a major factor of seat comfort in vehicles. In passenger vehicles, there is lacking research into the seat comfort of rear seat occupants. As accurate seat pressure measurement requires significant effort, simulation of seat pressure is evolving as a preferred method. However, analytic methods are based on complex finite element modeling and therefore are time consuming and involve high investment. Based on accurate anthropometric measurements of 64 male subjects and outboard rear seat pressure measurements in three different passenger vehicles, this study investigates if a set of parameters derived from seat pressure mapping are sensitive enough to differentiate between different seats and whether they correlate with anthropometry in linear models. In addition to the pressure map analysis, H-Points were measured with a coordinate measurement system based on palpated body landmarks and the range of H-Point locations in the three seats is provided. It was found that for the cushion, cushion contact area and cushion front area/force could be modeled by subject anthropometry, while only seatback contact area could be modeled based on anthropometry for all three vehicles. Major differences were found between the vehicles for other parameters.  相似文献

The purpose of this study was to compare the neuromuscular adaptations produced by strength-training (ST) and power-training (PT) regimens in older individuals. Participants were balanced by quadriceps cross-sectional area (CSA) and leg-press 1-repetition maximum and randomly assigned to an ST group (n = 14; 63.6 ± 4.0 yr, 79.7 ± 17.2 kg, and 163.9 ± 9.8 cm), a PT group (n = 16; 64.9 ± 3.9 yr, 63.9 ± 11.9 kg, and 157.4 ± 7.7 cm), or a control group (n = 13; 63.0 ± 4.0 yr, 67.2 ± 10.8 kg, and 159.8 ± 6.8 cm). ST and PT were equally effective in increasing (a) maximum dynamic and isometric strength (p < .05), (b) increasing quadriceps muscle CSA (p < .05), and (c) decreasing electrical mechanical delay of the vastus lateralis muscle (p < .05). There were no significant changes in neuromuscular activation after training. The novel finding of the current study is that PT seems to be an attractive alternative to regular ST to maintain and improve muscle mass.  相似文献

Abstract

In the last decades, sustainable concerns have increasingly gained importance to organizational survival, and Lean/Six Sigma approaches are becoming more and more outstanding in order to improve sustainability performance. This article aims to evaluate the degree of importance of sustainable performance measures of Brazilian organizations and to propose guidelines to achieve sustainability by aligning these measures with operational improvement programmes. Multiple data collection methods were applied as theoretical literature review, questionnaire survey and semi-structured interviews with industry professionals and academic researchers. The findings show that it is the corporate responsibility to focus their efforts on both operational improvement programmes and sustainable initiatives in order to achieve better environmental protection, corporate reputation, quality management, cost performance and suppliers relations, as they are considered to be more important on organizational sustainability.  相似文献

During the last decades, urban consolidation has been developed to minimize spatial expansion of cities, yet very few studies investigated whether it would actually reduce some negative effects of urbanization on biodiversity. In this study, we compared the invertebrate assemblages associated with two distinct urban forms (compact vs. conventional), focusing on two arthropod taxa often used as bioindicators, and dominant in urban habitats: spiders and carabid beetles. The following parameters were estimated: assemblage composition, species richness, activity-density total, per species (excluding seldom-recorded species) and per size class. The field collection was performed in 2009 using pitfall traps randomly set in hedgerows within 6 sites (representing 251 traps). A total of 4,413 spiders belonging to 117 species and 2,077 adult carabid beetles belonging to 39 species were collected. We found few significant differences in carabid beetle and spider assemblages between the two urban forms. The species richness of both groups was independent from the neighborhood design. Only four species of carabid beetles and ten of spiders significantly reacted to the neighborhood design, and no difference was found among the two designs for all other species. Large carabid beetles were more abundant and small spiders less abundant in the new neighborhood design compared to the conventional one. For both carabid beetles and spiders, no difference in assemblage composition was found between neighborhood designs. We therefore conclude that urban consolidation, by permitting a higher human density with similar arthropod assemblages, could contribute to reduce biodiversity loss in cities.  相似文献

This article examines and reflects on the methodology used in a research project that involved group work activities with parents of gender-variant children. Gender variance in children remains a topic people talk little about. Discussions about people who express themselves differently from the social norms attached to their birth sex, to a large extent, remain rarely discussed. They challenge a society organized largely on the basis of a binary understanding of identity, one that belongs to either male or female. This article discusses the concept of oppression as being central to the experiences of gender-variant children and young people and their parents, and it proposes social action research as a compatible and appropriate research framework for exploring their experiences. We describe the research process, identify its achievements, and explore issues that had to be confronted. We suggest that traditional research structures may benefit from being revisited in order to allow emancipatory research to more fully achieve its potential for both research and social action.  相似文献

This study examined 587 Turkish adolescents’ (Mage = 13.14, SD = 1.61) judgments and bystander responses towards hypothetical intragroup interpersonal (Turkish victim) and intergroup bias-based (Syrian refugee victim) bullying. Intergroup factors and social-cognitive skills were assessed as predictors. Findings revealed that adolescents were less likely to see bullying as acceptable and less likely to explicitly support the bully in intragroup interpersonal bullying compared to intergroup bias-based bullying. Further, adolescents with higher theory of mind and empathy were more likely to evaluate intergroup bias-based bullying as less acceptable and more likely to challenge the bully. Adolescents’ prejudice and discrimination towards refugees were predictors of bystander judgments and responses to intergroup bias-based bullying. This study provides implications for anti-bullying intervention programs.  相似文献

Seven tests of univariate normality are studied in view of their asymptotic power under local alternatives. The procedures under consideration are either based on the empirical skewness and/or kurtosis, including the popular Jarque-Bera statistic, as well as Cramér-von Mises, Anderson-Darling and Kolmogorov-Smirnov functionals of an empirical process with estimated parameters. The large-sample behavior of these test statistics under contiguous sequences is obtained; this allows for the computation of their associated local power curves and of their asymptotic relative efficiency in the light of a measure proposed by Berg and Quessy (2009). Comparisons are made under four classes of local alternatives, including those used by Thadewald and Büning (2007) in a recent Monte-Carlo power study. These theoretical results are related to empirical ones and many recommendations are formulated.  相似文献
