    Styckares arbetsmiljö: En studie om knivskärpa, olika knivstålskvaliteter, arbetssätt, samt fysisk ansträngning2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

     

    Styckare inom köttbranschen i Sverige ligger sedan länge i toppen av statistiken i Sverige, när det gäller yrken med de högsta relativa frekvenserna av anmälda arbetssjukdomar orsakade av belastningsfaktorer. Kniven är styckarens viktigaste verktyg och om den är slö ökar den fysiska belastningen med ökad risk för både belastningsskador och olycksfall. I denna studie på magisternivå var syftet att undersöka sambanden mellan knivens skärpa, knivens stålkvalitet, effekten av individens arbetssätt samt den fysiska ansträngningen vid styckning av nötkött. 12 personer vid två olika företag deltog i studien, under normalt arbete med styckning vid enkelbord under tre arbetsdagar. Tre olika knivstålskvaliteter utvärderades. Mätning av knivskärpa skedde med mätapparat Anago, samt med subjektiva skattningar enligt visuell analog skala (VAS). Tiden som kniven användes innan byte användes också som ett mått på hur länge skärpan kunde bibehållas. Ansträngningen hos styckarna undersöktes med mätning av hjärtfrekvensen under arbete, samt med skattning av ansträngning i händer och armar enligt VAS. Slutligen mättes eventuellt obehag/besvär före och under arbete med skattning enligt VAS.

     

    Det tycks som om det knivstål som var hårdare och inte finns på marknaden fungerade sämst, medan de övriga två var likvärdiga. Det finns indikationer på att det hårdare knivstålet påverkar andra egenskaper negativt, framförallt känslan av knivens följsamhet.

    Det föreligger en signifikant skillnad mellan olika individer i förmågan att bibehålla knivskärpa över tid, och de med obehag/besvär byter kniv oftare. Ytterligare studier krävs för att klargöra vad skillnaderna beror på, men sannolikt har både styckarens arbetsteknik, och företagets och individens rutiner för knivvård betydelse. Förbättrad utbildning inom dessa områden rekommenderas. Utvärderingen av knivtid indikerar att en styckare behöver 5-6 knivar per dag för att säkerställa att arbetet sker med vass kniv hela tiden.

    Det finns ett samband mellan dålig knivskärpa och lokal ansträngningskänsla i händer och armar. Något samband mellan knivskärpan och central ansträngning kunde dock inte påvisas i denna studie. Pulsvärdena visade att arbete som styckare innebär en hög belastning på andnings- och cirkulationsapparaten, och att de löper en stor risk att överskrida det rekommenderade gränsvärdet för energetisk belastning. Större undersökningsmaterial krävs dock för att dra säkrare slutsatser angående detta.

    Impact of experience when using the Rapid Upper Limb Assessment to assess postural risk in children using information and communication technologies2014In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 45, no 3, 398-405 p.Article in journal (Refereed)
    Abstract [en]

    The Rapid Upper Limb Assessment (RULA) is an observation-based screening tool that has been used to assess postural risks of children in school settings. Studies using eye-tracking technology suggest that visual search strategies are influenced by experience in the task performed. This study investigated if experience in postural risk assessments contributed to differences in outcome scores on the RULA and the visual search strategies utilized. While wearing an eye-tracker, 16 student occupational therapists and 16 experienced occupational therapists used the RULA to assess 11 video scenarios of a child using different mobile information and communication technologies (ICT) in the home environment. No significant differences in RULA outcome scores, and no conclusive differences in visual search strategies between groups were found. RULA can be used as a screening tool for postural risks following a short training session regardless of the assessor's experience in postural risk assessments.

    Myofeedback training and intensive muscular strength training to improve work ability and decrease pain among female workers on long term sick leave with neck pain: A Randomized Controlled Trial2011In: International Archives of Occupational and Environmental Health, ISSN 0340-0131, E-ISSN 1432-1246, Vol. 84, no 3, 335-346 p.Article in journal (Refereed)
    Abstract [en]

    The theoretical framework is that muscle tension in the neck is related to insufficient muscular rest and is a risk factor for chronic pain and reduced work ability. Promoting muscle strength and muscle rest may increase work ability and reduce neck pain. To test whether myofeedback training or intensive strength training leads to decreased pain and increased work ability in women on long-term sick leave. This is a randomized controlled trial of two 1-month interventions with myofeedback or muscular strength training in the home environment. Female human service organization workers (n = 60) on long-term (> 60 days) sick leave and with chronic neck pain were followed with self-reported and laboratory-observed data of health, pain, muscular activation, and work ability, at baseline, immediately after the intervention and 3 months after baseline. For both intervention groups, pain was lowered over time compared with the control group. Decreased pain and muscular activity was associated with increased self-rated work ability and with laboratory-observed work ability at 3-month follow-up. Decreased pain was also associated with increased self-rated work ability at 1-month follow-up. Muscular strength training was associated with increased self-rated work ability and mental health. Myofeedback was associated with increased observed work ability and self- rated vitality. The two interventions showed positive results, suggesting that they could be developed for use in health care practice to address pain and work ability. The intensive muscular strength training program, which is both easy to conduct at home and easy to coach, was associated with increased work ability.

    eHealth indicators: results of an expert workshop2012In: Studies in Health Technology and Informatics, Volume 180: Quality of Life through Quality of Information, I O S Press , 2012, 328-332 p.Conference paper (Refereed)
    Abstract [en]

    eHealth indicators are needed to measure defined aspects of national eHealth implementations. However, until now, eHealth indicators are ambiguous or unclear. Therefore, an expert workshop "Towards an International Minimum Dataset for Monitoring National Health Information System Implementations" was organized. The objective was to develop ideas for a minimum eHealth indicator set. The proposed ideas for indicators were classified based on EUnetHTA and De-Lone & McClean, and classification was compared with health IT evaluation criteria classification by Ammenwerth & Keizer. Analysis of the workshop results emphasized the need for a common methodological framework for defining and classifying eHealth indicators. It also showed the importance of setting the indicators into context. The results will benefit policy makers, developers and researchers in pursuit of provision and use of evidence in management of eHealth systems.

    Knife force differences when cutting meat at different temperatures2012In: NES2012: Ergonomics for Sustainability and Growth / [ed] Ann-Beth Antonsson, Kjerstin Vogel, Göran M Hägg, KTH Royal Institute of Technology, 2012Conference paper (Refereed)
    Abstract [en]

    Introduction

    Meat cutters in abattoirs is a group with high risks for musculoskeletal disorders. A major reason for this is that they exert high hand forces over a great part of the day when cutting meat. Though meat is refrigerated due to hygienic demands, meat temperature can vary. Meat cutters have claimed that knife forces increase with lower temperatures. This study was performed to find out what effects the meat temperature has on cutting forces. In addition, the same issue was addressed for pure fat.

    Method

    To be able to do cuts in meat under controlled conditions while measuring cutting forces, a machine, Anago KST Sharpness Analyzer, was used. The machine normally runs a knife at constant speed through a standardized textile ribbon while the force exerted on the ribbon is recorded over time. For this investigation, the ribbon was replaced by a wooden fixture with a 10 mm wide slot where the knife could pass and where meat samples could be fixed.Meat obtained from hind loin and fat tissue of pork was cut into 5 cm long, 4 cm wide and 2 cm thick samples. The meat fibre orientation was aligned with the long axis of the sample. When fixated in the fixture and the machine was started, the knife made a 4 cm long cut through 2 cm thick meat or fat.One hundred and forty four samples of meat and as many of fat were collected and put overnight in one of three refrigerators with temperatures 2, 7 and 12 °C, 48 in each. Well sharpened standard knifes were used for the tests. The knife was changed after 24 cuts. During the procedure samples were taken directly from the refrigerator and put into the fixture and tested immediately. The sample order was generally 2, 7, 12 °C to avoid systematic effects of a gradually blunter knife.

    Results

    There were no significant differences in knife forces at the three meat temperatures. The forces for fat were in average about three times higher than the meat forces. There was no significant difference between forces in fat at 7 and 12 °C. However there was a strongly significant difference between these two groups and the 2 °C fat group. The force was about 30% higher compared to the forces at 7 and 12 °C in fat.

    Conclusion

    In the range 2-12 °C there are no differences in meat. For fat there are no differences in the range 7-12 °C while the force increases about 30% when going from 7 to 2 °C.

    Chefsutbildning i Psykosocial Arbetsmiljörond: Utvärdering av en utbildningsinsats inom primär stressprevention2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Stress Prevention Project was a pilot project that took place in a global high-tech company during 2012-2014. The aim of the project was to identify the root causes of employees' perceived stress and to develop an approach for preventing these root causes. When the pilot project was completed a decision was taken that the intervention would be implemented throughout the organization. As a prelude to the intervention process all managers and HR personnel participated in a training session in “Psychosocial Work Environment Round”. The training included an introduction to psychosocial factors in the work environment and how these may affect employees, and a review of the questionnaire that was used to identify the psychosocial working environment and how its results should be interpreted.

     

    Aim: The aim of this study is to evaluate the initial training session, whether it is structured in a relevant way and what its content brings the intervention process.

     

    Limitations: The authors have only evaluated the initial training session that is a part of the larger intervention process.

     

    Method: The study was a qualitative interview study of interpretative and reflective approach. A selection of managers from three different training sessions and departments were asked to participate in the study. Participation was voluntary and all information treated confidentially. The interviews were carried out in focus groups of 2-4 participants. In exceptional cases individual interviews were conducted, this was because it was not possible to gather all the managers in the same session due to their different schedules.

     

    Results: The result shows that trainers and participants largely had the same perception regarding the aim and goals of the training session.  All goals were met with one exception.

     

    Despite completed training session several of the participants still felt unsure how to manage and affect the psychosocial work environment in their working group. However, they are satisfied with the training session as well as the intervention process. They consider the training to be important to secure the quality of the intervention. The participant inquire for a follow-up of the training session.

    Seat adjustment: capacity and repeatability among occupants in a modern car2008In: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 51, no 2, 232-241 p.Article in journal (Refereed)
    Abstract [en]

    Families in the Western world have a car and several family members share the same car. In this study, 154 participants have adjusted a driver's seat three times. The primary objective was to study intrapersonal repeatability and intraclass correlation (ICC) on seat; length adjustment, backrest angle, seat front edge and seat rear edge adjustment, related to participant age, sex, stature and weight. Length adjustment has the best intrapersonal repeatability within two repetitions, 49 mm and ICC-value 0.87. Females and younger participants (age < 40 years) adjust seats generally more accurately. Females adjust the seat 41 mm more forward, 120 mm compared to men 79 mm counted from 0-starting position. Females sit with more upright seat backrests, 46 degree compared to 43 degrees for males counted from 0-starting position. Females sit higher than males in both the frontal and rear part of the seat cushion.

    eQu riding therapy saddle: focused on children with cerebral palsy2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    There doesn´t exist yet a saddle which is mainly designed for therapeutic riding. What the therapist do nowadays is, that they use either normal saddles and add different devices with screws on, or they use a vaulting girth. Both of them are not the ideal solution and a saddle designed for therapeutic riding is needed. The goals were, to design a saddle where the child sits safer on the horse and the exercises can be done smooth, the therapist should have a stressfree job and the horse should feel comfortable through the entire therapy session.

    Comparison of two methods of voice activity detection in field studies2009In: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 52, no 6, 1658-1663 p.Article in journal (Refereed)
    Abstract [en]

    Purpose: To evaluate and compare the performance of 2 methods of voice activity detection (neck-attached accelerometer vs. binaural recordings) in field studies in environments where voice activity normally occurs.

    Method: A group of 11 healthy adults wore recording equipment during their lunch break. We used binary classification to analyze the results from the 2 methods. The output was compared to a gold standard, obtained through listening tests, and the probability for sensitivity (Ps) and false positive (Pf) was rated. The binary classifiers were set for consistent sensitivity of 99%; thus, the lower false positive rate would indicate the method with the better performance.

    Results: The neck-attached accelerometer (Pf = 0.5%) performed significantly (p < .001) better than the binaural method (Pf = 7%).

    Conclusion: The neck-attached accelerometer is more suitable than the binaural method for voice assessments in environments where people are speaking in close proximity to each other and where the signal-to-noise ratio is moderate to low.

    All-terrain vehicle use in agriculture: Exposure to whole body vibration and mechanical shock2010In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 41, no 4, 530-535 p.Article in journal (Refereed)
    Abstract [en]

    Whole body vibration (WBV) and mechanical shock were measured in 12 New Zealand farmers during their daily use of all-terrain vehicles (ATVs). As per the International Organization for Standardization (ISO) guidelines for WBV exposure, frequencies between 0 and 100Hz were recorded via a seat-pad tri-axial accelerometer during 20min of ATV use. The farmers were also surveyed to estimate seasonal variation in daily ATV usage as well as 7-day and 12-month prevalence of spinal pain. Frequency-weighted vibration exposure and total riding time were calculated to determine the daily vibration dose value (VDV). The daily VDV of 16.6m/s(1.75) was in excess of the 9.1m/s(1.75) action limit set by ISO guidelines suggesting an increased risk of low back injury from such exposure. However, the mean shock factor R, representing cumulative adverse health effects, was 0.31 indicating that these farmers were not exposed to excessive doses of mechanical shock. Extrapolation of daily VDV data to estimated seasonal variations of farmers in ATV riding time demonstrated that all participants would exceed the ISO recommended maximum permissible limits during the spring lambing season, as compared to lower exposures calculated for summer, autumn and winter. Low back pain was the most commonly reported complaint for both 7 day (50%) and 12 month prevalence (67%), followed by the neck (17% and 42%) and the upper back (17% and 25%) respectively. The results demonstrate high levels of vibration exposure within New Zealand farmers and practical recommendations are needed to reduce their exposure to WBV.

    Fatigue and recovery during and after static loading2014In: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 57, no 11, 1696-1710 p.Article in journal (Refereed)
    Abstract [en]

    Subjectively assessed endurance time (ET), resumption time (RT) and perceived discomfort, pain or fatigue (PD), and objectively measured maximum force-exerting capacity were investigated for varying loads and durations of a pushing task with two repeated trials. Beyond the main results quantifying how the load scenario affected ET, RT and PD, three additional results are of note: (1) although the maximum pushing force did not change between trials, shorter ET, longer RT and higher PD indicated accumulation of fatigue in Trial 2; (2) the PD ratings showed a trend with a linear increase during loading and a curvilinear decrease during recovery; and (3) the RT and the load level for different relative loading times were found to have an unexpected U-shaped relationship, indicating lowest fatigue at the intermediate load level. These results can be used to model a more sustainable and productive work-recovery ratio.

    Utveckling av medicintekniskt instrument för mätning av muskelstyrka2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta examensarbete inom biomekanik var ett produktutvecklingsprojekt av ett medicintekniskt instrument för mätning av statisk muskelstyrka i lårmuskulaturen (quadriceps). Instrumentet utvecklades med utgångspunkt från instrumentet Stig Starke som blivit föråldrat och förfallet. Stig Starke nyttjas främst av sjukgymnaster på Sahlgrenska universitetssjukhuset med syfte att exempelvis utvärdera effekter av sjukgymnastisk behandling. Behovet av en ny version av instrumentet är stort både inom kliniskt arbete och inom forskning. En ny version av instrumentet skulle hjälpa sjukgymnaster och forskare till att kunna fortsätta mäta muskelstyrkan i quadriceps på ett snabbt och enkelt sätt.

    Syftet och målsättningen med detta examensarbete var att utveckla Stig Starke-instrumentet så att mätningar av maximal statisk styrka i lårmuskulaturen (quadriceps), i enheten Newton, kan göras på patienter inom sjukvård och rehabilitering. En problemanalys i form av Workshop gjordes hos användarna på Sahlgrenska universitetssjukhuset. Problemanalysen tillsammans med en förstudie lade grunden för koncept i form av krav och önskemål till nya versionen av instrumentet. Önskemål på användarvänlighet av instrumentet och standardisering av patientens kroppsposition stod högt i prioritering.

    Via dynamisk produktutveckling och biomekaniska metoder där användarna (sjukgymnasterna) var i fokus kunde ett koncept väljas ut och tillverkas till en funktionell prototyp. Sex nyckelord för arbetet är quadriceps, muskelkraft, instrument, antropometri, användarvänlighet och standardisering. Funktionella prototypen visade via produktutvärdering att goda utvecklingsmöjligheter finns för den nya versionen, då den visade på hög användarvänlighet och standardisering. Behovet av en ny version av instrumentet kommer att finnas kvar tills ett likvärdigt instrument som Stig Starke kan tillämpas i verkligheten.

    IMPROVING SELF-RESCUE EQUIPMENT: Can a self-contained self-rescue unit be more comfortable to wear over long periods of time, not damage other equipment and be donned easily?2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A self-contained self-rescue unit is a device that is used in the mining industry in case of fires or release of toxic gases that depletes or contaminates breathable oxygen in the surrounding atmosphere. These units are the first line of defense by providing oxygen in a closed breathing cycle, allowing personnel to get themselves to safety.

    The goal of this project was to design a unit that is more comfortable to carry during the daily operations in and outside the mines. A unit that is easier to done and less likely to damage the users and/or surrounding mining equipment. It is developed in close collaboration with Atlas Copco, as the main sponsor, as well as Dräger and personnel working at Zink Gruvan Mining. 

    The result is a unit with an operational time of twenty minutes and a reduced size and weight. It’s position can be adjusted to be worn around the waist or the chest, depending on the tasks the user performs, as well as simplifying the donning procedure.

    Improving meat cutters' work: Changes and effects following an intervention2013In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 44, no 6, 996-1003 p.Article in journal (Refereed)
    Abstract [en]

    Meat cutters face higher risks of injury and musculoskeletal problems than most other occupational groups. The aims of this paper were to describe ergonomics changes implemented in three meat cutting plants and to evaluate effects related to ergonomics on the individual meat cutters and their work. Data was collected by interviews, observations, document studies and a questionnaire (n = 247), as a post intervention study. The changes implemented consisted of reducing knife work to a maximum of 6 h per day and introducing a job rotation scheme with work periods of equal length. Tasks other than traditional meat cutting were added. A competence development plan for each meat cutter and easy adjustment of workplace height were introduced. The questionnaire showed a reduction in perceived physical work load. In general, the changes were perceived positively. Figures from the company showed a positive trend for injuries and sick leave.

    Managers in healthcare organizations and their interactions with the media2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: The combination of three forces, the organizations’ desire for visibility, the citizens’ interest in the HSOs and the increasing pressure upon journalists to attract the interest of the audiences have all contributed to the fact that HSO managers nowadays have more interactions with the media than ever before.

    Aim: The aim of this thesis is to gain a deeper knowledge about HSO managers’ interaction with the media; their experience of the interaction, strategies and support.

    Method: The material of the study A was subject to a qualitative research approach along the lines of grounded theory, whereas content analysis was applied to study B.

    Results: The results show how the personal consequences as well as the consequences for their managerial practice vary in accordance with the extent to which the manager, the organization and the media attribute individual focus. The amount of support and from where within the organization the support was offered varied. When the managers did receive support from within their organization, it primarily came from co-workers or subordinates. Any strategies for interactions with the media were rarely organization-wide or even put into writing. Instead, they were defined by the managers themselves along the way.

    Discussion: The managers’ interactions with the media may be influenced both on a managerial and organizational level. Neither manager nor organization seem to profit from an individual focus, at least not in the long term.

    Conclusions: The result indicate the grade of reactions, stand in relation to the level of personification. Also the results suggests that this was influenced by the manager him- or herself, the organization as a whole and by the media. Managers tended to strive for an open and proactive strategy in relation to the media. They did not perceive much support and felt they were expected to handle the interactions with the media all on their own.
