    Engineering Quality Feelings: Applications in products, service environments and work systems2011Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Contemporary quality issues in product design are moving from materialistic to emotional user fulfillment; comprehensive research is needed to examine quality product feelings. This research is directed toward a deeper understanding of user and customer quality feelings for different product types, including services.

    The quality feelings concept includes dimensions of product quality, especially functionality, ergonomics and aesthetics. The first objective of this thesis is to identify, prioritize and synthesize quality feelings into product attributes in product development applications. The second objective is to explore, test and propose methodological approaches for designing quality feelings into products.

    Several methods from psychology, ergonomics, statistics and probabilistic methods and heuristics were applied to achieve the objectives. From a methodological viewpoint, Likert scales, free elicitation technique and Just About Right scales were applied for data collection. Multiple Regression, Factor Analysis, Correspondence Analysis, Genetic algorithms, Partial Least Squares (PLS) and Rough Sets (RS) were applied for data analyses. For ergonomic product evaluations, direct observations, 3D workload simulations, time and frequency analyses were conducted.

    Five product applications are included in this thesis: operator driver cabin design of reach trucks, steering wheel design trigger switch design in right-angled nutrunners, bed-making systemsproducts and waiting room environments.

    Heuristic methods were found effective when there is a high number of product attributes that interact to provide quality feelings. RS results are consistent with PLS attribute predictions. When the number of product attributes is large in comparison to the number of observations, PLS extracts informative results for quality feelings. The RS method is effective in identifying interactions among design attributes.

    Quality feelings are associated with both tangible (tactile characteristics) and intangible (quick and easy to use) product characteristics. Words such as safety, functionality, ergonomics, comfort, reliability, supportiveness, usability, feedback, pleasantness, attractiveness, durability and distinctiveness describe quality feelings from tangible products and services. Based on product type, the quality dimensions represented by these words possess different interactions and dependencies. In work environments, products act as prostheses between workers for social interaction, which need to be considered as important quality feelings dimensions.

    An Affective Engineering Assessment of a Hospital Bedding System Innovation2011In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126Article in journal (Other academic)
    Abstract [en]

    Developing bedding products requires consideration of human-product interactions such as usability and quality aspects besides ergonomics and productivity. Previous studies focus on finding associations between discomfort evaluations and physiological measurements of conventional bedding. The purpose of this study is to assess a new bedding system by observing affective and discomfort perceptions, physical loads, and time usage by nursing personnel. Fourteen nursese valuated a conventional and a new bedding system. Results suggest that nurses’ quality perceptions and overall experiences with the new bedding were positive. Considering physical loads the average time and frequency of bending forward were significantly lower for the new bedding versus conventional bedding. The time analysis yielded significant improvements to make a bed with the new bedmaking system. Quality perceptions were associated with tactile qualities (e.g. soft, nice to touch, etc.) and applicability (e.g. quick setup) for both bedmaking systems.

    Affective engineering evaluation of non-linear trigger switch mechanisms2011In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126Article in journal (Other academic)
    Abstract [en]

    The trigger switch mechanisms of nutrunners are important for operators to perceive feedback while tightening bolt joints. Previous studies focus on associations between discomfort evaluations and powered tool operation. This paper addresses how operator preferences are linked with functionality requirements from trigger switch mechanisms. Subjects evaluated five switch mechanism prototypes regarding perceptions of quality, feedback, firmness, and distinctness. Results suggest that loading and unloading phases of trigger operation are significant predictors of perceptions of quality. The trigger switch mechanism with a combination of high peak-drop-bottom forces was perceived with better quality, feedback, and distinctness in comparison to the other mechanisms. The study also revealed that when the switch mechanism was designed to give more distinctness and feedback, higher quality is perceived.

    Using Tentacles in Planning and Scheduling Work: Activities, Roles and Contributions2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Handling production scheduling is increasingly difficult for manyenterprises, and human involvement is necessary. The overall objective ofthis research was to gain further understanding of planners’ and schedulers’work within the manufacturing industry, to elucidate how their worksituation is formed, and to explain their significance to other employees’work and company activities. Scheduling work was studied in fourcompanies in the Swedish woodworking industry; a sawmill, a parquet floormanufacturer, a furniture manufacturer and a house manufacturer. Themethod used was activity analysis which is based on the analysis of workactivities in real work situations. Data collection included 20 days’observations and 65 interviews. Cross-case analysis with British cases onplanning work was also included.The findings revealed that the schedulers’ tasks lead to many activities. Twothirds of these are what can be expected. The remaining third constitutesactivities that depend on the schedulers’ individual attributes and the contextin which they work. The schedulers serve as problem solvers in a number ofdomains and constitute efficient information nodes, making them animportant service function. Furthermore, they have an alignment rolebetween different organizational groups. This role is specifically remarkablein dealing with production enquiries that must be aligned with productioncapability. Here, both planners and schedulers play an essential role inlinking the manufacturing and the commercial sides and their differentfunctional logics.Planners and schedulers in daily work exert strong influence on others. Theydo not hold legitimate power. Instead their influence emanates mainly fromaccess to and control of information and their ability to apply expertise tointerpret this information and examine the impact of decisions made acrossdifferent areas of the business. Personal power related to social skills is alsosignificant.Furthermore, they facilitate others’ work in continuous personalinteractions, serving the technical scheduling software system, and aligningdifferent organizational functions. In combination with expert knowledgeand developed social skills, they significantly contribute to quality operationsperformance. Finally, the schedulers influence the decision latitude of otheremployees and may indirectly promote job satisfaction, thus contributing todeveloping appropriate working conditions for others in the company.

    Implementering av Lean i medelstora företag: En lärande utvärdering om hållbarutveckling2010Report (Other academic)
    Abstract [sv]

    Denna rapport är ett av delresultaten från det interaktiva forskningsprojektet Produktionslyftet, inom HELIX VINN Excellence Centre. Projektet genomförs i samarbete med Produktionslyftet, ett nationellt program för spridande av managementkonceptet Lean produktion. Syftet med forskningsprojektet är att öka kunskapen om hur hållbart utvecklingsarbete kan bedrivas, både utifrån ett program- och företagsperspektiv.

    Rapporten beskriver två delstudier, en kvalitativ och en kvantitativ, som genomförts i samarbete med elva av företagen i Produktionslyftet, tio av dem pilotföretag för programmet. Den första delstudien genomfördes under sommaren 2008, genom en intervjustudie med programmets pilotföretag, medan den andra genomfördes under våren 2009, i formen av en enkätstudie med sju av företagen i programmet. Då en interaktiv forskningsansats har använts, så har i båda fallen den insamlade empirin från de båda delstudierna återkopplats till representanter från Produktionslyftet, samt programmets finansiärer, och en gemensam tolkning och analys av empirin har gjorts. Denna gemensamma tolkning har sedan analyserats utifrån modeller kring hållbart utvecklingsarbete och resultatet från detta arbete har sedan sammanfattats i två arbetsrapporter, som har återkopplats till programmet och dess finansiärer.

    Resultaten i delstudierna, samt den gemensamma tolkningen och analysen av empirin, fokuserar Produktionslyftets coacher, samt deras arbete med företagen. Dels spelar coacherna uppenbarligen en central roll i programmets arbete med företagen, och dels är coacherna mycket uppskattade av företagen. Coachernas arbetssätt, samt hur deras arbete påverkar möjligheten för företagen att skapa en hållbar utveckling, upptar också en central del i rapporten. Detta kan sammanfattas, som att om coacherna driver på arbetet för hårt, få finns det risk att det uppstår problem för företagen, men om coacherna inte är pådrivande så finns risken att åtminstone vissa av företagen inte tar sitt ansvar för Lean-arbetet. Med andra ord, coachernas arbete med företagen utgör en svår balansgång mellan att uppfylla företagens målsättningar med Lean-arbetet, i vägning mot Produktionslyftets mål och syfte. Men resultaten pekar också på vikten av att företagen har ett tydligt ägarskap och driv i utvecklingsarbetet.

    Slutsatsen i denna rapport blir därför att om programmets utvecklingsarbete skall bli hållbart, så hänger det troligen på dels att man har duktiga och kompetenta coacher, men också att man har en väl fungerande företagsrekryteringsprocess, där företag med ett internt driv för Lean-arbetet väljs till programmet.

    Leaninspirerade förändringar och personalens upplevelser2013In: Lean i arbetslivet / [ed] Sederblad, Per, Stockholm: Liber, 2013, 1, 103-121 p.Chapter in book (Other academic)
    Abstract [sv]

    De anställdas upplevelser av hur de kommer att påverkas av ett förändringskoncept är en avgörande faktor för om konceptet kommer att få reellt genomslag eller inte. Det här kapitlet behandlar denna centrala aspekt av leankonceptet – hur personalen upplever leaninspirerade förändringar. Just denna fråga finns det mycket lite empirisk forskning kring, så väl internationellt som i Sverige.

    I kapitlet redovisas en studie av personalens erfarenheter från leanarbetet i medelstora svenska tillverkningsföretag som ingått i det nationella programmet Produktionslyftet. Programmet kan ses som ett exempel på en ”svensk tolkning” av lean. Produktionslyftet har fått stort genomslag i den svenska diskussionen om lean, men samtidigt har konsekvenserna av lean ur ett arbetsmiljöperspektiv inte utvärderats på ett genomgripande sätt.

    Improvements, innovation and Lean2012Conference paper (Other academic)
    Abstract [en]

    Lean has become a dominating change concept in Sweden and in other countries. It has been discussed whether Lean is a support or an obstacle for improvement and innovation. The aim of this paper is to identify examples, opportunities and obstacles for improvement and innovation within the framework of Lean. Cases from 30 organizations have been analyzed. The empirical examples and also literature show that it is possible to work with Lean or Lean principles in a way that arenas of innovation and improvement are created, but that in other organizations this does not happen.

    The use of specific observation-based risk-assessment tools among professional ergonomistsManuscript (preprint) (Other academic)
    Abstract [en]

    Several observation-based risk-assessment tools have been developed in recent decades. However, studies reporting their use, the context in which they are used, and reasons for using them are scarce. The aims of the present study were to investigate the knowledge and use of observation-based risk-assessment tools and their usability and to explore the processes of assignments that include assessment of physical exposures. A web-based questionnaire (n=70) was combined with semi-structured interviews (n=12). The survey showed a limited use of several widely spread tools e.g. the NIOSH lifting equation, RULA and OWAS. The interviews revealed that the ergonomists mainly performed risk assessments based on their own expertise. Assignments were often initiated reactively, after identification of work-related musculoskeletal disorders, and seldom evaluated. The type of OHS organization and its relation to the client company seems to affect the opportunities for ergonomists to work proactively with risk assessment.

    Ergonomics at Home: Design for Safe Living and Home Care2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The home should represent safety and security for the person who lives there, and this is an important factor for independence and autonomy in very old age. With aging populations, the needs for long-term care increase, care provided by spouses and/or from the growing home care sector. Injuries among these groups are common.

    In this study, an ergonomics perspective was applied in the analysis of some basic daily activities performed by old persons and by home care workers, assisting.

    • The postures and movements of home care staff assisting at toilet visits, and transferring persons from wheelchair to toilet, were measured and analysed.

    • Some daily activities related to making food and washing clothes, performed by a group of persons between the age of 75 and 100, were measured and analysed.

    • The task of getting up from the floor – on your own and with the help of a walker equipped with a lifting device – was analysed with the help of older persons and nursing staff. The design was built on the knowledge gained from analysing how older people get up from floor.

    • Requirements for access with a four-wheeled walker in the local built environment were investigated.

    Observations were made with the help of video recording. Postures were recorded with the CUELA measurement system. The VIDAR ergonomics evaluation instrument was used to register the participants’ experiences of discomfort and pain during getting up from the floor with or without the walker with a lifting device. Structured interviews were used to find out about older peoples’ experience of using the four-wheel walker.

    It is concluded that ageing at home requires improved architectural and technical bathroom design and improved access in the local built environment.

    Getting up from the floor: Older peroples´ abilities and experiencesIn: Physiotherapy, ISSN 0031-9406, E-ISSN 1873-1465Article in journal (Other academic)
    Abstract [en]

    Objectives: To analyse the movement patterns of people over 75 years of age when getting up from the floor, and to find out what they describe as critical moments in getting up.

    Design: Observation of old people performing get up from floor and evaluation of experiences in VIDAR evaluation program.

    Setting: Tests were made in a laboratory environment

    Participants: 20 participants, eleven women and nine men. The mean age was 79 years.

    Result: Most elderly persons in this case did experience difficulties in getting up. The difficulties were mainly described in legs and were related to discomfort, weakness and balance issues. Most of the participants 18 of 20 made the getting up by themselves. The most of the participants 18 of 20 preferred a getting up including a position kneeling. The most critical part in getting were lifting one leg forward and then stretch the legs after kneeling, 17 of 18 described difficulties in this part.

    Conclusions: When developing aids to help persons to get up the main goal should be to reduce load on legs and support balance for the user. Training should include balance and muscle exercise of the leg.

    Helping in transfer from wheelchair to toilet: A case study analysing ergonomic postures in the bathroom for home care workers2013In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270Article in journal (Other academic)
    Abstract [en]

    BACKGROUND: Musculoskeletal disorders are common among home care workers, and the task of helping care recipients between wheelchair and toilet is described as particularly burdensome.

    OBJECTIVES: This study’s objectives were to find out where exposure to risks is highest for overexertion injuries in the task of helping a care recipient move between wheelchair and toilet, and to suggest how the bathroom environment or assistive devices could be improved to decrease risk of injury.

    METHODS: In a full-scale laboratory, home care workers helped persons move between wheelchair and toilet. The CUELA measurement system was used, combined with video observation, to record postures assumed during the task.

    RESULTS: Maximum back inclination on average exceeded 40 degrees. This angle is, combined with rotation of the back and the weight of the care recipient, well over recommended limits for helping in the task. The knees were exposed to a particularly heavy load when the wheelchair was adjusted, taking off leg-rests.

    CONCLUSIONS: Solutions should be developed which increase possibilities for the care recipient to participate and bear much of the load. Development of wheelchairs and other assistive devices should include usability aspects for the assisting care workers.

    Work Postures When Assisting People at the Toilet2015In: Ergonomics in design, ISSN 1064-8046, E-ISSN 2169-5083, Vol. 23, no 2, 16-22 p.Article in journal (Other academic)
    Abstract [en]

    The aim was to analyze the home care workers’ movement patterns and postures of their backs, relating them to risks while helping an ambulatory care recipient to/from the toilet in a homelike environment. We found severe risks of unpredictable movements with exposed postures could explain many injuries. Because of high risk injuries, we suggest decreasing the time when the care recipient stands and the home care worker helps with clothing and personal hygiene. Another suggestion to decrease high risk is development of support in front of the recipient to prevent her/him falling forward.

    Assessment and design of industrial manual handling to reduce physical ergonomics hazards: – use and development of assessment tools2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Despite efforts of reducing harmful physical ergonomics exposures related to manual handling, the occurrence of heavy or repetitive manual handling, and non-neutral postures is high in many occupational sectors. To reduce these exposures, interventions and job design strategies can utilize risk assessment. A need was identified of an observation-based tool which supported occupational health and safety practitioners for assessments of risk factors related to manual handling.

    The aim of this thesis was to explore the use and important usability-related aspects of observation-based assessment tools among professional ergonomists, and to develop new research based assessment and screening tools, to present their scientific basis and to evaluate their reliability and usability. A web-based questionnaire was employed to gain knowledge on the use and usability aspects of risk assessment tools among ergonomists in Sweden. The assessment tools RAMP I and RAMP II were developed in an iterative process, including literature searches, expert group judgments, and with input from more than 80 practitioners. The reliability and usability evaluations included assessments and ratings by practitioners.

    The thesis points to a low use of several internationally spread assessment tools among Swedish ergonomists, and a relatively higher use of tools promoted by the Swedish Work Environment Authority. Several usability-related aspects were identified as important, such as being easy and quick to use, its ability to communicate and visualize the results, and its ability to facilitate improvement measures. The developed tools support assessment of a broad range of risk factors related to manual handling. The thesis supports that assessments with acceptable reliability can be achieved for the majority of items of the two developed tools. The thesis supports that the tools are usable in supporting risk assessments targeting risk factors related to industrial manual handling.

    Development and evaluation of RAMP I: a practitioner tool for screening for musculoskeletal disorder risk factors in manual handlingManuscript (preprint) (Other academic)
    Abstract [en]

    RAMP I is a screening tool developed to support practitioners in screening for work-related musculoskeletal disorder risk factors related to manual handling. RAMP I, which is part of the RAMP tool, is based on research based studies combined with expert group judgments. More than 80 practitioners participated in the development of RAMP I. The tool constitutes of dichotomous assessment items grouped in seven categories. Acceptable reliability was found for a majority of the assessment items for 15 practitioners who were given 1h training. The usability evaluation points to RAMP I being usable for screening for musculoskeletal disorder risk factors, i.e., usable for assessing risks, usable as a decision base, has clear results, and the time needed for an assessment is acceptable. It is concluded that RAMP I is a valuable tool for practitioners.

    Reaching at Sustainable Development: Lean in the Public Sector2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The concept of sustainable development is commonly used worldwide. In the public sector, characterized by a rationalization focus, conclusions about the sustainability of lean production (lean), as a management concept for organizational change, are contradictory. This thesis aims to identify conditions promoting sustainable development in the public sector, in particular the healthcare sector, when implementing lean. Two qualitative and one quantitative case study were conducted using longitudinal data collection: focus group interviews, semi-structured interviews, analysis seminars, steering board meetings, and a questionnaire. The empirical data was collected from national lean programs in Sweden. The results describe that socio-technical principles may be used as indicators of sustainability as well as a guide in the implementation of lean in healthcare. Active ownership among stakeholders, a developmental view in the organization, stakeholder participation, organized joint innovative learning activities, role and goal clarity may be conditions influencing the sustainability of lean in the public sector. Furthermore, when supported by a favorable lean context, the results show that the lean tools value stream mapping, standardized work and 5S (housekeeping) may promote a sustainable implementation of lean in healthcare by the promotion of employees and managers’ working conditions and/or employee individual innovation. Visual follow-up boards may inhibit employees and managers’ job satisfaction, when not supported by job resources. Personnel stability, time for development, and information to be able to participate were in this context shown to be central job resources. In conclusion, conditions which may promote sustainable development in the public sector, when implementing lean are: stakeholder values of inclusive social well-being, an implementation process including stakeholder ownership and joint innovative learning, and a favorable lean context: balancing job resources and job demands. Lean tools may empower public healthcare employees to engage in development and counteract a poor implementation process and a poor lean context but only to a limited degree. The lean contexts studied were unfavorable, i.e., a weak implementation process and job resources not balancing the job demands. Hence, the lean implementations studied could not be considered sustainable.

    On Effect Assessment in Work Environment Interventions: A Literature Overview and Methodological Reflection2010In: Industrial Engineering Publications and ResearchArticle in journal (Other academic)
    Abstract [en]

    Despite many positive case studies our overview of the work environment intervention (WEI) research literature finds mixed results. There is support for the profitability of WEI investments such as training and personnel policies at the organisational level but less clear results for disorder reductions. The financial benefits of WEIs were greater for performance gains than for reduced sickness costs. Multifactor interventions are widely seen as key to successful intervention but are difficult to evaluate and unused in experimental studies. Review inclusion criteria excluding studies with good interventions but non-experimental evaluations, pose a quality criteria selection bias. Difficulties in proving WEI effectiveness may depend on views of what constitutes good scientific quality. WEI effects are clear in some cases but are difficult to show in others. Evaluation poses methodological challenges that contribute to the lack of clear evidence for WEI effectiveness. There is a need for more practical multifactor WEIs and non-experimental evaluation strategies suited to today’s complex systems.

    RELEVANCE: Ergonomists and managers should understand that the problems in 'proving' the effectiveness of ergonomics are related to perceptions of what constitutes proof. Progress in the practise of ergonomics should recognise the difficulty of organisational change, the weaknesses of experimental traditions, and the need for multifactor interventions that reach deep into the work process to maximise impact. Isolating effects is difficult but this does not mean no effects exist.

    Distriktsveterinärer i Bil: Arbetsmiljöenkät, Fältstudie, Underlag till fordonsspecifikation2006Report (Other academic)
    Abstract [sv]

    Studien

    En studie av distriktsveterinärernas arbetsmiljö vid arbete i och runt bilen har genomförts vid KTH:s skola för teknik och hälsa i samarbete med Jordbruksverket och Svenska Distriktsveterinärföreningen och med finansiellt stöd från Utvecklingsrådet.

    Enkät

    En enkät om bilen som arbetsmiljö besvarades av 95% av distriktsveterinärerna. Av denna framgår att

    • endast fyra uppger att de ej kör bil i tjänsten,
    • 67% kör bil i jobbet dagligen, 60% av kvinnorna och 76% av männen,
    • 86% kör VW Passat,
    • 40% hoppar in och ut ur bilen mer än 10 ggr/dag,
    • uppgivna körsträckor varierar mellan 1000-8000 mil/år, medianen är 3000 mil,
    • 59% använder dator i bilen.

    Bilen får goda omdömen vad gäller väghållning, vinterkörning, säkerhet, klimat/ventilation, motorstyrka, instrumentering, sikt, sittkomfort vid körning, mindre bra omdömen om stiga i/ur, lastutrymmets rymlighet och tillgänglighet, hur utrustning transporteras och huruvida bilen är funktionell som arbetsfordon. Bilen får negativa omdömen för arbetsställningar vid lasthantering och mest negativt är arbetsställning vid datorarbete.

    Ungefär hälften av (47%) uppger att de har fysiska besvär som de sätter i samband med arbetet i bilen. Andelen kvinnliga distriktsveterinärer med kortare tid i yrket än 10 år (46%) är dubbelt så stor som motsvarande andel bland de manliga distriktsveterinärerna (21%). Bland de kvinnor som arbetat kortare än 10 år som veterinär är andelen som rapporterar besvär 47%. Motsvarande andel bland männen var 27%. 91% uppgav att de är mycket eller ganska nöjda med sitt arbete.

    Fältstudier

    Sex stationer besöktes och 12 veterinärer (8 kvinnor, 4 män) intervjuades, deras arbetsoperationer i och runt bilen filmades/analyserades och EMG registrering av belastningar i övre extremiteter/rygg/nacke genomfördes.

    Samtliga intervjuade angav att de hade besvär i form av smärta från muskler eller leder, 10 av 12 från rygg/nacke/axlar, de övriga från knä respektive höft.

    Arbetet i bilen upptar mellan 2-4 timmar av arbetsdagen, man kör ca 3000 mil/år. De arbetsoperationer som registrerades och analyserades inkluderade i och urstigning, telefonering, datoranvändning, lasthantering, samt användning av olika packsystem.

    Resultaten från analyserna indikerar sammanfattningsvis bl.a. att

    • insteget i bilen och förarstolens läge är lågt,
    • de som använder dator i bilen anser att arbetsställningen är olämplig,
    • arbetsbelysning i bilen är bristfällig, speciellt för telefon- och datorarbete,
    • bilen upplevs som trång och med otillräcklig lastkapacitet,
    • låg lastlucka hindrar upprätt arbetsställning för långa,
    • bilarna ofta har lös utrustning eller ej fixerat datorbord under färd,
    • kontorsutrustningen gör att batteriet ofta laddar ur,
    • det finns inte plats för passagerare/praktikant i bilen.

    Underlag till specifikation för nytt arbetsfordon

    Ett antal förslag till designkrav för ett nytt arbetsfordon för distriktsveterinärer inkluderar aspekter på trafiksäkerhet, komfort, datorarbetsplatsens förutsättningar, utformning och placering, belysningsergonomi, lasthantering, hygien och strömförsörjning.

    I rapportens bilagor redovisas enkätens frågor, intervjuschema för fältstudien, data och exempel från fältstudien samt slutligen sex möjliga designlösningar för ett arbetsfordon med datorarbetsplats.

    Ergo-Index Slutrapport Etapp 1: Resultat från litteraturstudie och försöksstudie2008Report (Other academic)
    Abstract [sv]

    Målet med detta projekt är att vidareutveckla Ergo-Index modellen, som kan användas för att analysera olika sätt att utföra ett arbete på och välja det lämpligaste ur både belastningsergonomiska och produktionsekonomiska aspekter. I Etapp 1 sammanfattas i denna rapport. Här har målet varit att i) samla kunskap om sambanden mellan belastning, belastningstid och återhämtningsbehov samt risken för belastningsskador och ii) samla data som ger underlag för modellering av återhämtningsbehovet. Etapp 1 har till största delen finansierats av SBUF, Svenska Byggbranschens Utvecklingsfond, och till del av de medverkande organisationerna.

     

    En litteraturstudie baserad på främst databassökningar i Medline, Ergonomics Abstracts och Scopus genomfördes med huvudfokus på samband mellan belastningsnivå, belastningstid, återhämtningsbehov samt modeller inom detta område. En försöksstudie med 10 medverkande från rörbranschen som gjorde sammanlagt 160 försök genomfördes i syfte att få fram data om samband mellan belastningstid, belastningsnivå och återhämtningsbehov. I försöken tryckte de medverkande på ett handtag på en armlängds avstånd framför kroppen i ögonhöjd. Belastningsnivån och belastningstiden varierades mellan olika försök. Såväl subjektiva metoder, t ex skattningar enligt Borg’s CR-10 och RPE skala, som objektiva metoder som kraftmätning och tidtagning användes. Resultaten har bearbetats med statistiska metoder och regressionsanalys har använts för inledande modellering.

     

    Exponentiella samband bestämda genom kurvanpassning av försöksdata presenteras, såväl för uthållighetstid (funktion av belastningsnivå) som för återhämtningstid (funktion av belastningsnivå och relativ belastningstid). Högre belastningsnivåer leder till kortare uthållighetstider. Tiden för återhämtning efter belastning som pågått under en relativ belastningstid (fraktion av uthållighetstiden) minskar generellt med minskande belastning för att sedan öka igen vid låga belastningar. Återhämtningstiden är längre för belastningar motsvarande 10 % av maxkraften än vid 30 % vid relativ belastningstid. Sådana data har, enligt författarens kännedom, inte rapporterats tidigare. Däremot, om man normerar återhämtningstiden med reella belastningstiden tenderar denna kvot att vara konstant, vilket innebär att återhämtningstiden är proportionell mot belastningstiden, med olika proportionalitetskonstant för olika belastningsnivåer. Denna proportionalitet är tydligare för belastningscykel 1 än för cykel 2. Vidare visar resultaten att uthållighetstiden är kortare och återhämtningstiden längre vid en upprepad belastning, vilket indikerar att trötthet ackumuleras.

     

    Litteraturstudien har gett viktiga resultat exempelvis vad avser olika trötthetsmekanismer, olika typer av belastningssituationer, könsskillnader och psykosociala faktorer. Resultaten från både försöksstudien och litteraturstudien bidrar med viktig kunskap till den vidareutvecklingen av Ergo-Index modellen som kommer att utföras i projektets Etapp 2. I rapporten diskuteras vilka faktorer som bör inkluderas i den fortsatta modellutvecklingen.

    Ergonomics and its Consequences for Businesses2011Conference paper (Other academic)
    Abstract [en]

    As ergonomists, for many of us, a driving force is to improve work environments to “do good”:  to reduce risks for injury and human suffering, improve working conditions and support human well-being. This motivation is in accordance with the first of the two objectives of ergonomics as in the IEA definition – ‘…to optimize human well-being and overall system performance”. However, ‘doing good’ in this sense can be difficult. A challenging task we face as ergonomists is to motivate work site improvements within a business environment that is focused on the second objective of ergonomics, overall system performance. Thus, the art of ergonomics lies in balancing the two – in addressing individual wellbeing as well as the broader goals of system performance. As part of this balancing act, displaying financial impacts of ergonomics plays an important role and is therefore the focus of this key-note.

    In all business activity decision makers have to choose between different investment options. For investments that can improve ergonomics, the full economic benefits are often difficult to quantify. Such benefits are associated with reduced costs related to non-optimal work environment. Visible costs, such as direct costs for absenteeism, are quite easily measured while hidden costs, related to business key parameters, such as productivity and quality issues, are often complex, contextually dependent and difficult to estimate. However, these issues are vital for organizations and such costs, which directly affect the company’s competitiveness, are often many times greater than the visible costs.  If decision makers only are aware of the direct financial impact of investments they may prioritize solutions that are not optimal neither for organizational performance and business results nor for the work environment and health of the employees. In extreme cases this can jeopardize the company’s future.

    So, what is needed for informed decision-making?  First, awareness that ergonomics also influences core business parameters and organizational performance is needed. Second, there is a need for user-friendly assessment tools to estimate the financial effects associated with workplace ergonomics. In the presentation a survey of existing assessment tools and methods is presented. Reasons why these tools aren’t more widely used are discussed.

    There is an increased call from companies for assessment tools that companies can use in their operational management to motivate and carry out ergonomic improvements. This is partly due to the need to form business cases to motivate investments. There is also an increased awareness from company management, who recognize that improved working environments also lead to other positive effects for the company. Increasingly managers seek knowledge for informed decision making, for example when prioritizing between work environment improvements and strategic corporate decisions.  The assessment tools can be used i) proactively in the design of production systems, which leads to advantages for the staff as well as for the company’s performance, ii) reactively to evaluate different scenarios to reduce work environment, productivity and quality problems and iii) strategically for promoting the company.

    So, what actions are needed to improve these assessment tools, increase their use of and make them a natural part in the company operational processes? In this presentation some research and development suggestions are given. These involve tool as well as organizational and process development.

    In summary, working towards improved tools and their usage in striving towards the twofold ergonomics objective involves many challenges, but strengthens the possibilities to be successful in “doing good”, for individuals and organizations, as well as for societies.

    Social capital in healthcare: A resource for sustainable engagement in organizational improvement work2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Social capital, work engagement, working conditions, and leadership are concepts that have been studied previously, but there is lack of knowledge about what processes promote sustainable organizational improvement work in hospitals, and specifically, what leads healthcare professionals to engage in clinical developments.

    The overall aim of this thesis is to increase knowledge of how social capital and engagement contribute to sustainable organizational improvement work in hospitals and how social capital and engagement are created during organizational improvement work. Data were collected by a questionnaire at three times over a period of two years at five hospitals and all studies are quantitative.

    The results show that improved working conditions and employees’ attitudes to engagement in improvement work are associated with and have importance for healthcare professionals’ work engagement and clinical engagement in improving care processes (Study I). Job demands, social capital, and other job resources are associated with healthcare professionals’ intention to leave their jobs, whereas high levels of social capital are associated with low levels of intention to leave (Study II). Increased social capital predicted healthcare professionals’ job satisfaction, work engagement, and engagement in patient safety (Study III). Leadership is shown to be important for healthcare professionals’ social capital, and levels of leadership quality correlate with levels of social capital over time (Study IV).

    In conclusion, social capital, increased job resources, and decreased job demands are important conditions for healthcare professionals’ engagement in organizational improvement work. To develop social capital, leadership quality is an important precondition. Social capital can be regarded as a resource for sustainable organizational improvement work in healthcare, because of its importance for healthcare professionals’ engagement, job satisfaction, and intention to leave.

    Abstract [en]

    Employees in an eye hospital spend many hours in semidarkness or darkness performing visually demanding activities that can cause fatigue and eye strain. As preparation for the planning of a new eye hospital, this project was initiated in order to produce knowledge of how to improve lighting in examination rooms. Current light conditions at S:t Erik Eye Hospital were assessed including questionnaires to employees/patients, and measurements of luminance, space analyses and energy consumption. Visits to other prominent eye hospitals and a literature review were performed. The questionnaires revealed that eyestrain problems were common in eye care professionals, especially in women. Working in dark rooms increased the subjective feeling of fatigue. Many, but not all, lacked daylight. The general lighting system was often insufficient with poor light distribution, shadows, and a colour temperature that in general was too low. Improvements included possibilities to regulate inflow of daylight, installation of remote controls, and timing and level of adaptation to different light levels. These improvements have been tested in a real scale installation that used the latest technology in terms of artificial lighting, a lighting control systems and a novel solution to control daylight. Five different light scenarios were preinstalled and evaluated by professionals and patients. A majority reported an improvement compared with traditional solutions. Current and actual energy consumption was monitored. Simulations of future consumption points to a possible energy reduction by 50 %, using new lighting technology, daylight and optimal room design. With improved logistics, new buildings and new work organization, energy savings can be even higher, around 70 %.

    Styckares arbete: knivskarpt om hållbarhet2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [sv]

    Styckares arbete är fysiskt ansträngande och kännetecknas av att vara utpräglat manuellt där den handhållna kniven är det viktigaste verktyget. Arbetet innebär enligt arbetsskadestatistiken hög risk för arbetsrelaterade skador och sjukdomar.

    Syftet med avhandlingen är att identifiera och utvärdera arbetsmiljöförbättringar som styckningsföretag och anställda styckare i samverkan och under beaktande av systemeffektivitet kan vidta. Ett andra syfte är att ge ett kunskapsbidrag som branschen kan tillämpa i sin framtida arbetsmiljöutveckling.

    Avhandlingen baseras på det arbete som genomfördes i två forskningsprojekt (STAR respektive SKARP). Dessa bedrevs som en branschintervention, i en interaktiv ansats och med styrgrupper med deltagare från branschorganisationen Kött- och Charkföretagen samt representanter från styckningsföretag och livsmedelsarbetarnas fackförening.

    De studier som ingår i avhandlingen har huvudsakligen genomförts i reell miljö som kvasi-experimentella fallstudier. Styrgrupperna i projekten samt de aktuella företagen deltog i planering och utvärdering av dem.

    Resultaten visade att styckningsarbete är så fysiologiskt krävande att många styckare ingående i mätningarna låg över den nivå som rekommenderas för att arbetet skall vara hållbart. Avhandlingen rekommenderar därför att den fysiska arbetsbelastningen på individnivå i styckningsarbete inte ska överstiga 30 Relative Aerobic Strain (RAS), dvs. den andel av sin fysiska förmåga uttryckt i syreupptagning som individen använder i sitt arbete. Vidare visar resultaten att ökad arbetstakt försämrar kvalitet och utbyte samt företagens lönsamhet. En ökad arbetstakt upplevs dessutom negativt av styckarna. Polering av knivarna istället för att slipa dem innebär att kniven kan bli vassare, dess livslängd förlängs och därmed minskar kostnaderna för knivslitage samtidigt som risken för belastningsskador minskar.

    För den enskilde individens hållbara anställning i styckningsarbete föreslås flera åtgärder: bl.a. att införa ett system för förbättrad knivskärpa där utbildning och teknik för att hålla knivarna vassa ingår samt att organisera arbetet med en anpassning av teknik, arbetstakt och arbetstyngd som främjar styckarnas hälsa.

    Interaktiviteten i projekten resulterade i ökat samarbete om arbetsmiljön mellan styckningsföretagen och med Arbetsmiljöverket. För att arbetsmiljöförbättrande åtgärder ska bli hållbara samt även ge ett bidrag till företagets lönsamhet bör de ske i samverkan med samt engagera de anställda.
