Många antällda på monteringsband exponeras ofta för ergonomiskt ofördelaktiga arbetsuppgifter och arbetsförhållanden. De handhållna monteringsverktyg som används genrerar ofta reaktionskrafter som i många fall kan orsaka en känsla av obehag eller ge upphov till mer bestående hälsobesvär. De kraftfulla och repetetiva arbetsuppgifterna som montering många gånger innebär kan bana väg för förluster i arbetskraftskapacitet, vilket i sin tur kan leda till stora förluster i produktivitet och produktkvalitet. En paraplyterm för de många åkommor och besvär som kan uppstå som ett resultat av användandet av handhållna monteringsverktyg är ’förslitningsskador’ (Cumulative Trauma Disorders på engelska). Målsättningen för denhär studien har varit att undersöka de ergonomiska effekter som användandet av handhållna monteringsverktyg innebär vid olika vektygs- och arbetsuppgiftsrelaterade parametrar. Studien genomfördes med hjälp av en test rig där ett simulerat verktygshandtag utnyttjades. Den ergonomiska effekten på användaren undersöktes genom mätningar av uppnådda reaktions moment och handtags vinklar associerade med olika åtdragningsstrategier, styvhet av förband samt orientering av arbetsyta. Genom att mäta muskelaktiviteten i underarmen hos testpersonerna erhölls en kvantifiering av den fysiologiska effekten på testpersonerna. Mätningarna av vinkel, moment och muskelaktivitet kombinerades med subjektiva skattningsmetoder för att på så sätt kunna erhålla ett mer holistiskt perspektiv på åtdragningarna och deras effekt på människan. Resultaten från studien underströk de negativa effekterna av åtdragning med Quick Step strategin på medium hårda förband, oavsett orientering av arbetsytan. Turbo Tight och Tensor Pulse strategierna genererade de lägsta reaktions momenten och handtags deflektionerna. Resultaten från muskelsaktivitetsmätningarna och de subjektiva skattningsmetoderna bekräftade den relativa mildheten hos Tensor Pulse och Turbo Tight strategierna. Dessutom påvisades att åtdragningar som sker på en horisontell arbetsyta resulterade i lägre handtagsdeflektion jämfört med åtdragningar på en vertikal arbetsyta, oavsett åtdragningsstrategi och styvhet hos förband.

Ett flertal studier har visat att arbetsmiljön påverkar företags effektivitet. Företagsledningen är sällan medveten om till vilken grad arbetsmiljö-problem påverkar produktivitet, kvalitet och sjukfrånvaro. Litteraturstudien i detta projekt visade att förbättringar inom ergonomi generellt sett är kostnadseffektiva. Det är mest gynnsamt att arbeta proaktivt samt participativt, det vill säga i samarbete med medarbetarna på den lokala avdelningen. Ett effektivt, systematiskt arbete med riskbedömningar och interventioner minskar behovet av att göra en beräkning av lönsamheten. Propositioner för egenskaper hos kostnadseffektiva beräkningsmetoder togs fram i denna studie. Dessa propositioner var; ” Enkelhet och god användbarhet”, ”rätt innehåll för målgruppen”, ”hög förmåga att bedöma risk”, ”personalfokus”, ”korrekta standardiserade värden”, ”rätt fokus” och ”optimal design”. Scania CV, producent av lastbilar och bussar, har tagit fram en beräkningsmodell för kostnadseffektivitet hos ergonomiska interventioner. Utvärderingen av denna modell med semistrukturerade intervjuer visar god samstämmighet i att det behövs enkla kalkylmetoder som grundar sig på systematiska riskbedömningar.

A major goal of ergonomics consists in having an adequate workload in order to improve levels of comfort, satisfaction, efficiency and safety. Otherwise, its inadequacy can influence health and worker’s safety and affect the organization. The aim of this study is to identify the root causes of inadequate workload in spite of understanding the influencing factors and their interconnections to improve the workers health and safety. The specific objectives are: (i) understand and define the dimensions of the workload through a systematic literature review; (ii) identify the substantial influencing factors (root causes) of the inadequacy of the workload by analyzing a systematic review using Thinking Process tools; (iii) evaluate the workload and its inadequacies in a participatory manner, by measuring and identifying their root causes in a manufacturing company. To achieve each objective, this study was structured with three articles associated with each of the specific objectives. Therefore, the work is consisted of a systematic review of the literature (Article 1), analysis of a systematic review (Article 2) and an applied case study (Article 3). The first article understood and defined the dimensions of workload. In the second, we identified the major influencing factors of inadequate workload through a systematic review. In the third article, we conducted a case study, comprising the assessment of workload through the NASA TLX, demonstrating the maximum risk workload (overall workload). The end result allowed us to perceive few studies defining workload between empirical articles, there is no standard definition. It was felt that the focus of the articles are not in addressing the appropriateness of this workload. Allowed to identify the root causes of inadequate workload, providing a thorough analysis of the general relations of the problem, by logical cause and effect, including the influential factors and their interconnections.

Att på förhand bestämma vilken mängd resurser som krävs nästa vecka eller nästa månad kan vara både en komplicerat och riskfylld uppgift beroende av situation, trots att man känner till när resurserna behövs. Intermittent efterfrågan, eller lågrörlig efterfrågan, är när många perioder saknar efterfrågan och plötsligt sker en efterfrågan en period. Detta gör det svårare att prognostisera. Om efterfrågan underskattas kommer det att leda till förlorad försäljning och därmed förlorade intäkter. Om efterfrågan är överskattad kommer det i bästa fall att bara leda till ökat lager eller, i värsta fall, leda till osålda produkter och till slut inkurans. Artiklar med intermittent efterfrågan kan utgöra upp till 60 % av det totala lagervärdet för samtliga artiklar.Denna uppsats avhandlar prognoser av intermittent efterfrågan samt hur prognosfelen ska mätas för den valda eller de valda prognosmetoderna. Fyra prognosmetoder utvärderas med nästan 18 månaders empirisk efterfrågedata från ett tillverkande företag. De utvärderade metoderna är exponentiell utjämning, Croston och två modifierade varianter av Croston; Syntetos och Boylans metod samt modifierad Croston av Segerstedt. Fyra olika startvärden och åtta utjämningskonstanter används. Prognosmetoderna utvärderas med olika typer av prognosfel; varians (MSE och MAD), bias (CFE samt max- och minvärde av CFE) och sMAPE. Vidare sker utvärdering med ett komplimenterande mått för bias, Lagerperioder (Periods in Stock, PIS). PIS tar tidsaspekten i beaktande och inte bara storleken på prognosfelen. Dessutom undersöks två varianter av MAD och MSE. För att förbättra utvärderingen av biasmåtten undersöks procentantalet av de efterfrågetillfällen som en prognosmetod inte kan uppfylla.Förhållandet mellan de olika prognosfelen undersöks med hjälp av principal component analysis (PCA). Prognosfelen undersöks även med binär logistisk regression för att utröna huruvida vissa prognosmetoder gynnas av vissa prognosfel. Den logistiska regressionen baseras på deskriptiv statistik för tidsserierna samt medelabsolutförändringen som tar ordningen för tidserien i beaktande såväl som variationen. Rankning och kvoter mellan olika prognosfel från olika metoder är andra tillämpade metoder. Resultatet av forskningen både bekräftar och motsäger tidigare forskning. Bland de bekräftande resultaten är den bias olika prognosmetoder har. Croston och modifierad Croston överskattar efterfrågan, Syntetos och Boylans metod underskattar efterfrågan. Exponentiell utjämning är förhållandevis fri från bias när utjämningskonstanterna har låga värden. De avvikande resultaten är att CFE inte är lämpligt att använda när antal prognosperioder är begränsat. Värdet för CFE kan indikera att prognosen är fri från bias när både PIS och procentandelen icke mött efterfrågan. PIS är dessutom mindre känslig för transienta efterfrågehändelser som kan förvränga CFE. PIS rekommenderas som ett biasmått när tidsserien är ändlig, särskilt när det gäller intermittent efterfrågan, tillsammans med måttet procentandelen icke mött efterfrågan. Andra resultat är att MAD inte är pålitlig eftersom måttet, under vissa förhållanden, gynnar prognosmetoder som underskattar efterfrågan

Aided-diagnosis software in imaging are now integrated to radiological workflow but they are also key elements in medical research. Defined as medical devices, recent regulatory changes now impose clinical evaluations on manufacturers. The pharmaceutical industry benefits from a proven method in drug evaluation. Yet, transposition to medical devices is not fully effective and even more complex in the case of software. The aim of this thesis is to propose a clinical evaluation and validation methodology for these devices. The first part introduces the normative and regulatory framework as well as methodologies from various areas. The synthesis of these data allows the presentation of the first methodology item enabling the clinical evaluation of software performance. In order to further the analysis, the second part of the methodology is dedicated to evaluation/validation of software ergonomics, a sensitive issue in medical software. Finally, to restore these devices to their true place in health care, the last item proposes to highlight their impact in clinical practice and in patient management, through their implication in the search for new biomarkers in imaging. These various methods comply with and go beyond the regulatory framework in order to meet the expectations of all the stakeholders involved in the life cycle of aided-diagnosis software in imaging. To conclude, an example of its application is presented showing the impact of a dedicated software in the evaluation of oncology response in imaging

Action forces have been identified as risk factors. Therefore, the collection and analysis of action forces is an essential part of the ergonomic evaluation. Up to now, there was a lack of a standardized and systematic approach to evaluate action forces, especially in the automotive production. Thus, in the present thesis a methodical approach is described to evaluate action forces systematically. The thesis is divided into four studies. The first study contains the identification of the variety of action forces in the different manufacturing areas of automotive production. The second study describes the detailed analysis of action forces in the assembly shop, which is the manufacturing area with the highest count of action forces in the automotive production. The third study describes the direct measurement of action forces in laboratory conditions. The action forces are applied by a testing machine. The fourth study consists of the direct measurement of action forces, which are applied by subjects. Thereby, the methodical approach to perform direct measurements has been evaluated. The findings of the thesis can be used as a guideline, to evaluate action forces in the automotive production. Also the findings highlight the potential for further research projects

This thesis aims to provide tools for improving ergonomics at work environments. Some work activities in industry are commonly executed by workers in a non-ergonomic fashion, which may lead to musculoskeletal disorders in the short or in the long term.Work-related Musculoskeletal Disorders (WMSDs) are a major health issue worldwide, that also represents important costs both for society and companies. WMSDs are known to be caused by multiple factors, such as repetitive motion, excessive force, and awkward, non-ergonomic body postures. Not surprisingly, work environments with such factors may present an incidence of WMSDs of up to 3 or 4 times higher than in the overall population.Here, our approach is to evaluate the human motion with respect to ergonomics indexes, optimize the motion, and intervene on the task based on the optimized motion.To evaluate the body posture ergonomics, we developed a Digital Human Model (DHM) simulation capable of replaying whole-body motions.In simulation, the initial movement can be iteratively improved, until an optimal ergonomic whole-body motion is obtained.We make the case that a robot in physical interaction with a human could drive the human towards more ergonomic whole-body motions, possibly to an ergonomically optimal motion. To design a robot controller that influences the body posture, we first investigate the human motor behavior in a human-human co-manipulation study. In this human dyad study, we observed motor behavior patterns that were used to design a collaboration controller for physical human-robot interaction (pHRI). In a new study, the same co-manipulation task was then executed by humans collaborating with a Franka Emika Panda robot

The aim of this work is to systematize the development of an educational software, maximizing its capacity to support learning, through the description of each one of its phases, from the first requirement analysis to the evaluation of learning, putting a methodology together. To achieve this goal, it is important to supply a framework for the integration of the development team with teachers and students, during the educational project, the implementation and evaluation. As a product of this methodology, an educational software (whose context is chemical equilibrium, for high school) was built, and its efficiency (in terms of learning) was experimentally evaluated through an educational activity, on a presence teaching environment. In the end of this investigative process, it is verified that the interface’s design phase is as important as the educational planning phase. In the end of this work is discussed the need of an expert in education on the team, because there is an indication that his presence is more significant for the success of the product than the presence of other professionals (for instance: programmers, designers, writers, etc). Therefore, it follows that the methodological proposition made in this work optimizes the participation of the members of the team, routing their abilities to the required activities, and that this strategy reflects in good software products.

As atuais pesquisas em Ergonomia do Ambiente Construído investigam os usuários e sua relação com o ambiente através de métodos específicos com foco na Ergonomia física e na percepção do usuário. Pretende-se nessa pesquisa analisar o Método Constelação de Atributos orientada para a percepção do usuário e a partir desta, propor um novo método. O estudo do método, bem como sua aplicação será exemplificado através de pesquisa realizada utilizando as cozinhas residenciais como aplicação prática da pesquisa. A cozinha é um dos ambientes que mais tem sofrido sensíveis mudanças nos aspectos sociais, econômicos, tecnológicos, ergonômicos, entre outros. Faz-se um resgate histórico desde espaço desde a Idade Média até as atuais cozinhas utilizadas pela sociedade brasileira. Realiza-se uma busca pelas legislações e normas técnicas que definem os espaços de cozinhas em apartamentos multifamiliares, através dos Códigos de Obra e Edificações de seis capitais brasileiras e avalia-se a Norma NBR 14033 que trata de mobiliário de cozinhas residenciais. Durante a realização desta pesquisa avaliou-se o Método Constelação de Atributos sua aplicação e resultados em uma pesquisa aplicada e ainda, em outras duas dissertações de mestrado onde o método também foi utilizado. A partir de análises realizadas propõe-se uma nova metodologia como forma de aprimorar e qualificar os atributos atribuídos a um ambiente construído por parte de especialistas e usuários, fundamentado na metodologia já existente. A nova metodologia é aplicada a um grupo de especialistas e usuários na cidade do Rio de Janeiro. Conclui-se o trabalho com a definição detalhada de uma nova metodologia de investigação da percepção do usuário frente ao ambiente construído.
The current research in the Built Environment Ergonomics investigate users and their relation ship to the environment through specific methods with focus on ergonomics physical and perception of the user. It is intended that research examine the existing methodologies for user perception and propose a new method. The target system used in this study are the home kitchens, this environment has been more sensitive to changes in social, economic, technological, ergonomic, and others. It is a historical review from space since the Middle Ages to today s kitchens used by Brazilian society. Held a search for the laws and technical standards that define the spaces of kitchens in apartments multifamily, through the Building Codes Work and in six Brazilian cities and assesses the technical standard NBR 14033 of furniture that comes from home kitchens. During this research evaluated the Constellation Method Attributes its application and results in experimental research and two dissertations where the method was also applied. From the analysis carried out and some pre-tests performed developed a new methodology as a way to enhance and qualify the attributes assigned to an environment built by experts and users. So, we propose a new method based on existing methodology. The new methodology is applied to a group of experts and users in Rio de Janeiro. It is working with the detailed definition of a new methodology for the investigation of perception of the user facing the built environment.

This study addressed the usability experiences of users by exploring the human errors and the learnability situation of the authentication systems. Authors conducted a case study to explore the situation of human errors and learnability of authentication systems. Observation and interviews were adapted to gather data. Then analysis through SHERPA (to evaluate human errors) and Grossman et al. learnability metric (to evaluate learnability) had been conducted. First, the authors identified the human errors and learnability issues on the authentication systems from user’s perspective, from the gathered raw data. Then further analysis had been conducted on the summary of the data to identify the features of the authentication systems which are affecting the human errors and learnability issues. The authors then compared the two different categories of authentication systems, such as the 1-factor and the multi-factor authentication systems, from the gathered information through analysis. Finally, the authors argued the possible updates of the SHERPA’s human error metric and additional measurable learnability issues comparing to Grossman et al. learnability metrics. The studied authentication systems are not human errors free. The authors identified eight human errors associated with the studied authentication systems and three features of the authentication systems which are influencing the human errors. These errors occurred while the participants in this study took too long time locating the login menu or button or selecting the correct login method, and eventually took too long time to login. Errors also occurred when the participants failed to operate the code generating devices, or failed to retrieve information from errors messages or supporting documents, and/or eventually failed to login. As these human errors are identifiable and predictable through the SHERPA, they can be solved as well. The authors also found the studied authentication systems have learnability issues and identified nine learnability issues associated with them. These issues were identified when very few users could complete the task optimally, or completed without any help from the documentation. Issues were also identified while analyzing the participants’ task completion time after reviewing documentations, operations on code generating devices, and average errors while performing the task. These learnability issues were identified through Grossman et al. learnability metric, and the authors believe more study on the identified learnability issues can improve the learnability of the authentication systems. Overall, the authors believe more studies should be conducted on the identified human errors and learnability issues to improve the overall human errors and learnability situation of the studied authentication systems at presence. Moreover, these issues also should be taken into consideration while developing future authentication systems. The authors believe, in future, the outcome of this study will also help researchers to propose more usable, but yet secured authentication systems for future growth. Finally, authors proposed some potential research ares, which they believe will have important contribution to the current knowledge. In this study, the authors used the SHERPA to identify the human errors. Though the SHERPA (and its metrics) is arguably one of the best methods to evaluate human errors, the authors believe there are scopes of improvements in the SHERPA’s metrics. Human’s perception and knowledge is getting changed, and to meet the challenge, the SHERPA’s human error metrics can be updated as well. Grossman et al. learnability metrics had been used in this study to identify learnability issues. The authors believe improving the current and adding new metrics may identify more learnability issues. Evaluation of learnability issues may have improved if researchers could have agreed upon a single learnability definition. The authors believe more studies should be conducted on the definition of learnability in order to achieve more acceptable definition of the learnability for further research. Finally, more studies should be conducted on the remedial strategies of the identified human errors, and improvement on the identified learnability issues, which the authors believe will help researchers to propose more usable, but yet secured authentication systems for the future growth.

Sequeira, Movin. "Developing decision-support tools for evaluation of manufacturing reshoring decisions." Licentiate thesis, Tekniska Högskolan, Jönköping University, JTH, Industriell produktutveckling, produktion och design, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-48263.
Under de tre senaste decennierna har många företag flyttat sin produktion till lågkostnadsländer för att kunna utnyttja lägre lönekostnader. Många gånger har företagen genom denna åtgärd lyckats sänka sin tillverkningskostnad men samtidigt drabbats av oförutsedda problem kopplat till exempelvis produkt-kvalitet och möjligheten att kundanpassa produkter. Hanteringen av problemen har lett till ytterligare kostnader som många gånger överstigit besparingen i tillverkningskostnad. Detta har lett till att allt fler företag börjat flytta tillbaka sin produktion till hemlandet, så kallad reshoring. Reshoring är ett ungt område där det saknas forskning gällande bland annat hur den här typen av beslut på bästa sätt kan utvärderas och vilken typ av beslutstöd som kan underlätta den här typen av beslut. Därför är syftet med den här avhandlingen är att utveckla beslutsstödverktyg för utvärdering av reshoring beslut. För att uppfylla syftet har två forskningsfrågor formulerats. Den första frågan handlar om hur industriexperter resonerar kring reshoring beslut (RQ1) medan den andra frågan handlar om hur deras resonemang kan modelleras i beslutsstödverktyg (RQ2). Tre studier har genomförts för att besvara forskningsfrågorna, en fallstudie och två modelleringsstudier. Fallstudien fokuserar på att identifiera vilka kriterier som industriexperter beaktar medan modelleringsstudierna fokuserar på att utveckla beslutstödsverktyg där en del av dessa kriterier beaktas, med hjälp av fuzzy logic och analytical hierarchy process (AHP). Resultaten från forskningen visar att industriexperter bedömer reshoring beslut utifrån ett holistiskt perspektiv. En stor del av dessa beslutskriterier finns inom konkurrenskraft kategorin och inom dessa, har industriexperterna lagt högst vikt på kvalitet och lägst vikt på hållbarhet. Genom fuzzy logic modellering modellerades kriterierna på en övergripande nivå. Tre nya fuzzy logic koncept utvecklades för att fånga experternas resonemang. Dessutom utvecklades två konfigurationer med sexton olika inställningar, och de bästa identifierades. AHP-baserade verktyg utvecklades för att fånga experternas resonemang om kriterierna för konkurrenskraft prioriteringar. Fuzzy logic-baserade verktyg kan bättre fånga experternas resonemang kring reshoring beslut. Denna forskning bidrar till teori med en holistisk lista över beslutskriterier för reshoring beslut, och till praktik med beslutsstöd verktyg för utvärdering av reshoring beslut.

Trots ansträngningar för att minska belastningsergonomiska exponeringar relaterade till manuell hantering är förekomsten av exponering av riskkällor såsom tung eller repetitiv manuell hantering, obekväma arbetsställningar, hand–armvibrationer och helkroppsvibration omfattande inom flera sektorer. Dessa belastningsergonomiska exponeringar tros i betydande utsträckning bidra till en stor andel av arbetsrelaterade muskuloskeletala besvär och arbetssjukdomar inom flera sektorer som exempelvis tillverkningsindustrin. Riskbedömningar kan användas inom det förebyggande arbetet kopplat till interventioner eller arbetsutformning för att minska dessa skadliga exponeringar (risk faktorer), vilket även är ett krav om arbetet innefattar manuell hantering eller andra riskkällor. Trots det stora antalet observationsbaserade bedömningsverktyg utvecklade för att stödja riskbedömningar av arbete som innefattar manuell hantering identifierades ett behov av ett nytt observationsbaserat bedömningsverktyg som stödjer praktiker i utförliga bedömningar av flertalet riskfaktorer relaterade till manuell hantering och som ger stöd i det systematiska arbetsmiljöarbetet. Syftet med avhandlingen är att utforska användningen av, och viktiga användbarhetsrelaterade aspekter av observationsbaserade bedömningsverktyg bland professionella ergonomer som arbetar i Sverige. Dessutom är syftet även att utveckla nya forskningsbaserade screeningverktyg och bedömningsverktyg, presentera deras forskningsbas samt att utvärdera deras reliabilitet och användbarhet. En webbaserad enkät användes för att inhämta kunskap om i vilken omfattning dessa verktyg används av professionella ergonomer och vilka användbarhetsrelaterade aspekter som ansågs särskilt betydelsefulla för dessa verktyg. För att utveckla de nya verktygen (dvs. RAMP I och RAMP II) genomfördes litteratursökningar för att identifiera kvantitativt beskrivna riskfaktorer relaterade till manuell hantering och betydelsefulla faktorer som påverkar arbetstagares kapacitet vid manuell hantering. Verktygen utvecklades i en iterativ process med input från mer 80 praktiker, varav mer än 30 professionella ergonomer, samt expertgruppsbedömning. De två verktygen utvärderades med avseende deras interbedömarreliabilitet utifrån bedömningar genomförda av ergonomer och ingenjörer/tekniker utifrån videofilmade arbeten inom industriell manuell hantering. Verktygens användbarhet utvärderas av 20 praktiker med en pappersenkät och verktygens ’användarvänlighet’ av 22 ergonomer. Avhandlingen pekar på en relativt låg proportionell användning av flera internationellt spridda bedömningsverktyg bland professionella ergonomer som arbetar i Sverige, och en relativt hög proportionell användning av bedömningsverktyg som stöds av Arbetsmiljöverket. Flera användbarhetsrelaterade aspekter identifierades som betydelsefulla bland ergonomerna, i synnerhet betydelsen av att bedömningsverktygen är enkla och snabba att använda, deras förmåga att kommunicera och visualisera resultatet av bedömningar, och deras förmåga att stödja åtgärdsarbetet. Det utvecklade screeningverktyget och bedömningsverktyget stödjer bedömning av flertalet riskfaktorer relaterade till industriell manual hantering. Avhandling ger stöd att majoriteten av verktygens bedömningspunkter har acceptabel interbedömarreliabilitet och förbättringsområden för verktygen har identifierats. Avhandling ger stöd att de två utvecklade verktygen är användbara vid riskbedömningar av belastningsergonomiska riskfaktorer relaterade till industriell manual hantering.

Resumo: Afecções osteomusculares representam um sério problema de saúde pública, causando absenteísmo, afastamentos e incapacidade funcional nas diversas categorias de trabalhadores. Questionários são considerados úteis para investigar os sintomas osteomusculares, sendo possível identificar fatores do ambiente trabalho associados com o desenvolvimento desses distúrbios. Os objetivos deste estudo foram traduzir e adaptar culturalmente o instrumento Work Role Functioning Questionnaire para o português falado no Brasil, assim como avaliar sua confiabilidade para aplicação em indivíduos com distúrbios osteomusculares. A adaptação cultural foi realizada conforme as recomendações da literatura internacional, obedecendo as etapas de tradução, retro-tradução, e revisão por um comitê de especialistas. Foi realizado pré-teste com a participação de 30 indivíduos com sintomas osteomusculares. As propriedades psicométricas foram avaliadas após a participação de 105 sujeitos portadores de sintomas osteomusculares e 105 indivíduos sem sintomas. A confiabilidade foi avaliada por meio da consistência interna e estabilidade, com resultados satisfatórios para o instrumento como um todo (alfa de Cronbach = 0,95). Na avaliação de cada sub-escala, o alfa de Cronbach foi maior que 0,85, exceto para aquela que avalia a demanda social. O Coeficiente de Correlação Intraclasse, que avaliou a estabilidade teste-reteste, foi satisfatório para a demanda mental (0,68) e excelente para as demais (0,82 ¿ 0,91). Na avaliação da validade de constructo, por meio da comparação entre os grupos, a pontuação média obtida foi menor para as demandas física, de plano de trabalho, e de produção para o grupo de indivíduos com sintomas osteomusculares. Houve diferença significativa entre os dois grupos na comparação dessas demandas (p<0,001). Os dados demonstram que o processo de adaptação cultural foi realizado com sucesso e que a versão do instrumento obtida apresenta propriedades psicométircas confiáveis para utilização na população brasileira.

Abstracts: Musculoskeletal disorders represent a serious problem in public health, resulting in absenteeism, loss of work and disabilities. Questionnaires have been considered useful to identify musculoskeletal symptoms and to investigate correlated factors in workplace. The study objectives were to translate and adapt the Work Role Functioning Questionnaire into the Brazilian Portuguese language and evaluate its reliability in patients suffering from musculoskeletal disorders. The cross-cultural adaptation was performed according to the internationally recommended methodology, using the following guidelines: translation, back-translation, revision by a committee and pretest. The pretest was carried out with 30 patients suffering from musculoskeletal disorders. Psychometric properties were evaluated by administering the questionnaire to 105 subjects with musculoskeletal disorders and receiving physical therapy treatment. The reliability was estimated through stability and homogeneity assessment. The construct validity was tested comparing the 105 subjects suffering from musculoskeletal disorders to 105 healthy workers. The results indicated good content validity and internal consistency (Cronbach alpha= 0,95). Cronbach alpha for each scale was > 0,85, except for the social demand scale. The Intraclass Correlation Coefficient for the test-retest reliability was satisfactory for mental demands (ICC= 0,68) and excellent for the others (0,82 ¿ 0,91). In relation to the construct validity, the mean score obtained for each scale was lower for physical, work scheduling, and output demands in the subjects with musculoskeletal disorders. There was a significant difference (p<0,001) between the groups in comparison to work scheduling, physical and output demands. The data showed that the cross-cultural adaptation process was successful and the adapted instrument demonstrated psychometric properties making it reliable to use in the Brazilian culture.

Ergonomics changes in the work place interfere in the relation between over operators work and health. This case study had as its objective to analyze the repercussions of a process of changes technical and organizational due to ergonomic projects in a school material plant. Two company sectors were selected which are responsible for the main product external completion. One of the sectors received the full ergonomic intervention and the other had only little adjustments. In order to develop this study, the following procedures were executed: questionnaire applications, observations in order to understand the work activity in both sectors and interviews with the objective of comprehending different actors perception of changes in the in the company. The results indicated that, after the ergonomic intervention, there was a reduction in absenteeism due to RSI/WRMD, changes in physical and cognitive task requests, a differentiated interpretation of results for each social group in the company and na appropriation, by the company, of the results and transformation process started by the ergonomic project for other purposes. This case study revealed the importance of the evaluation process of an ergonomic intervention, because it confirms that a positive result in relation to the demand that originated the intervention, will not always grant future improvements. The analyzed situation points to new problems, whose repercussions are not yet known, but need to be discussed.
As modificações ergonômicas no ambiente de trabalho interferem na relação entre saúde e trabalho. Este estudo de caso teve como objetivo analisar as repercussões do processo de mudanças técnicas e organizacionais decorrentes dos projetos de ergonomia de uma empresa do setor de material escolar sobre o trabalho e a saúde dos operadores. Foram selecionados dois setores responsáveis pela etapa de acabamento externo do principal produto da empresa. Um setor recebeu a intervenção ergonômica e o outro sofreu pequenas modificações. Para o desenvolvimento deste estudo foram realizados os seguintes procedimentos: aplicação de questionários, observações para compreender a atividade de trabalho nos dois setores e entrevistas para percepção das mudanças nos diferentes atores da empresa. Os resultados apontaram que após a intervenção ergonômica houve diminuição dos afastamentos por LER/DORT, modificações nas exigências físicas e cognitivas das tarefas, uma interpretação dos resultados da intervenção diferenciada para cada grupo social da empresa e apropriação pela empresa dos resultados e do processo de transformação do projeto de ergonomia para outros fins. O estudo deste caso revelou a importância do processo de avaliação de uma intervenção ergonômica, porque confirma que um resultado positivo em relação à demanda da intervenção nem sempre irá garantir condições de trabalho satisfatórias. A situação estudada aponta novos problemas cujas repercussões ainda são desconhecidas, mas que necessitam ser discutidas.

Work organization aspects has become increasingly important in the field of ergonomics, since they can affect both the health of workers as productivity, profitability and product quality. Therefore, this thesis has as main objectives to investigate the organization of work in a more conceptual perspective and in a more applied and for that two studies were conducted; one of them being a systematic review and the other a study a application of two different approaches to assessment of the organization. Study 1. Work organization, although currently very studied, does not present a consensus on the concept and also on the tool to be used to evaluate this aspect. This makes it difficult to compare results and to provide scientific evidence. Thus, the aim of the first study was identify the tools available in the literature to assess the organizational aspects of the work environment. Methods: We performed searches in major databases. Two reviewers independently selected relevant studies. We included studies that evaluated the organization of work and reporting tool used for this purpose. The psychometric properties of the tools used in the studies were checked and content of the tools was analyzed in the light of NIOSH concept of work organization. Data were analyzed descriptively. Results and Conclusions: The electronic search yielded 4431 references. At the end of the selection process, 43 studies were included and 15 tools were identified to evaluate the organization of work. The tool used for the most os the studies was the Job Content Questionnaire (JCQ) (49%). Considering the definition of organization of the NIOSH study, only two tools included 50% of items of that definition. The external context of work was neglected in studies, have been evaluated in a single item by the tool proposed by Howard et al. Few psychometric properties were reported in the studies reviewed. Thus, studies are needed to evaluate more organizational aspects systematically and methodological quality to contribute to the conceptual and operational understanding of this construct. Study 2. After identifying these tools, analysis of its contents and considering that for a more accurate assessment of work organization, it might be necessary to consider both the worker's perspective, as the observer, a second study was proposed with the objective of assess the organizational aspects of nursing staff in both perspectives. Methods: A total of 163 nurses of three sectors of the were analysed. Work organization was evaluated using two tools, the JCQ and the checklist proposed by Howard et al. Data were analyzed descriptively and by statistical tests (Chi-square). Results and Conclusions: There was a significant difference between the three sectors for control (p = 0.050) and social support (p = 0.030). The sectors had common aspects related to the general functioning of the hospital. The different aspects related to the task performed, the content of the work, female predominance in the sectors and the possibility of informal break. Few items of the two instruments correlated with each other, suggesting that they contemplate different aspects of the organization. Therefore, it is suggested that these instruments are used in addition. These results confirm the great variety of instruments identified in Study 1 and therefore the lack of consensus on the definition.
Os aspectos da organização do trabalho tem se tornado cada vez mais importantes no campo da ergonomia, uma vez que podem afetar tanto a saúde do trabalhador quanto a produtividade, rentabilidade e qualidade do produto. Diante disso, a presente tese tem como objetivos principais investigar a organização do trabalho tanto sob uma perspectiva mais conceitual, quanto mais aplicada e, para tal foram realizados dois estudos; um deles sendo uma revisão sistemática e o outro um estudo de aplicação de duas abordagens diferentes de avaliação da organização. Estudo 1. A organização do trabalho, apesar de atualmente, muito estudada, não apresenta um consenso sobre o seu conceito e também sobre a ferramenta a ser utilizada para avaliação desse aspecto. Isso dificulta a comparação dos resultados e o fornecimento de evidências científicas. Assim, foi proposto o estudo 1 com o objetivo de identificar as ferramentas disponíveis na literatura para avaliar os aspectos organizacionais do ambiente de trabalho. Métodos: Foram realizadas buscas nas principais bases de dados. Dois revisores independentes selecionaram os estudos pertinentes. Foram incluídos estudos que avaliaram a organização do trabalho e que relataram a ferramenta utilizada para esse propósito. As propriedades psicométricas das ferramentas utilizadas pelos estudos foram checadas e o conteúdo das ferramentas foi analisado à luz do conceito da NIOSH sobre organização do trabalho. Os dados foram analisados descritivamente. Resultados e Conclusões: A busca eletrônica resultou em 4431 referências. Ao final do processo de seleção, 43 estudos foram incluídos Foram identificadas 15 ferramentas utilizadas para avaliar a organização do trabalho. A ferramenta mais utilizada pelos estudos foi o Job Content Questionnaire (JCQ) (49%). Considerando a definição de organização do trabalho do NIOSH, apenas duas ferramentas incluíram 50% dos itens constituintes dessa definição. O contexto externo do trabalho foi negligenciado nos estudos, tendo sido avaliado em um único item pela ferramenta proposta por Howard et al. Poucas propriedades psicométricas tiveram avaliação relatada nos estudos. Assim, são necessários estudos avaliando maior número de aspectos organizacionais, de forma sistemática e com qualidade metodológica para contribuir com a compreensão conceitual e operacional deste construto. Estudo 2. A partir da identificação dessas ferramentas, análise de seus conteúdos e considerando que para uma avaliação mais precisa da organização do trabalho, poderia ser necessário considerar tanto a perspectiva do trabalhador, como do observador, foi proposto um segundo estudo com o objetivo de avaliar os aspectos organizacionais de trabalhadores de enfermagem sob ambas perspectivas. Métodos: Foram avaliados 163 profissionais de enfermagem de três setores de um hospital. A organização do trabalho foi avaliada por meio de duas ferramentas, o JCQ e o checklist proposto por Howard et al. Os dados foram analisados descritivamente e por meio de testes estatísticos (Chi-square). Resultados e Conclusões: Houve diferença significativa entre os três setores para os domínios controle (p=0.050) e apoio social (p=0.030). Os setores apresentaram aspectos comuns relacionados ao funcionamento geral do hospital. Os aspectos divergentes relacionaram-se à tarefa realizada, ao conteúdo do trabalho, predomínio de gênero feminino nos setores e possibilidade de pausa informal. Poucos itens dos dois instrumentos apresentaram correlação entre si, sugerindo que estes contemplem aspectos diferentes da organização. Portanto, sugere-se que esses instrumentos sejam utilizados complementarmente. Esses resultados corroboram a grande diversidade de instrumentos identificados no Estudo 1 e, consequentemente, a ausência de consenso na definição.

The broad field of digitalisation finds its first applications in the German working environment under the term "Industry 4.0". This bachelor thesis examines industrial assistance systems that can be made available to employees in many different ways, with the goal to support the performance of work tasks. The systems can be used as portable microcomputers on the body or implemented as a comprehensive processing system for company production data. The thesis examines two concise examples from this area of employee assistance in manufacturing companies. To date, a constantly growing number of assistance systems on the market can only be characterised by advertising and product concepts. The aim of this thesis is to analyize the two example systems from an ergonomics point of view as well as suitability for day-to-day business and employee-friendly operations. In the theoretical basics, a general understanding of terms from the field of digitalisation is developed. Furthermore, an overview of the example systems utilized is provided based on their product presentations. These systems are evaluated by an industry expert using qualitative research method to determine core statements from various areas, such as ergonomics and usability
