      Abstract: Academic dishonesty is not new and has been shown to occur from school level all the way through to tertiary institutions. Furthermore, it is not just scholars/students who are guilty but more concerning, academic staff. Academic dishonesty or academic misconduct can include plagiarism, deception, fabrication, cheating, sabotage, bribery and/or impersonation. In an attempt to promote principles of best practice for publishing, The International Journal of Cardiology published a set of guidelines which should be applied to all submissions to this journal.

  • User-centric design considerations for women's functional protective wear
           for the construction industry in southern Africa
    • Authors: Bongiwe Kolisi; Mugendi K. M'Rithaa
      Abstract: This discussion paper highlights the preliminary findings of an investigation into ergonomic considerations in the design of women's protective clothing. The study investigates the assumption that there is a dearth in the product offerings of the women's protective wear that are empathic, ergonomically designed with good fit, and offer acceptable levels of comfort for women working in the construction trade. The research employs a qualitative research method - including interviews with key actors such as women working in the construction industry, manufacturers, and suppliers. The unique morphological features associated with steatopygia that are common in the sub-region, and yet not fully accommodated in the design of context-responsive work wear, are discussed in this paper.The paper explores prevailing attitudes amongst manufacturers and suppliers to motivate them to offer superior products for women in the construction industry. A higher adoption rate of the redesigned women's protective wear could correlate to reductions in downtime associated with general occupational health and safety issues, as well as the nugatory impact of low levels of comfort, protection and garment fit. Subsequently, a boosted self-confidence and higher levels of motivation occasioned by a positive body image would validate the efficacy of the intended ergonomic design intervention.

  • A comparison between skinfold callipers and ultrasound imaging for
           assessing body composition in recreationally active students
    • Authors: Kim Nolte; Reon A. Van der Merwe, Cindy A. Helena, Heinrich W. Nolte Julia Van der Meulen
      Abstract: The measurement of skinfold thickness by means of skinfold callipers (SC) is a widely accepted method to assess subcutaneous fat thickness and percentage body fat (%BF). Ultrasound imaging (USI) is a more recent technology that is becoming accessible for the same application. The objective of this study was to compare measurements recorded by SC and USI for the assessment of subcutaneous fat thickness in order to estimate %BF. Thirty adults volunteered for the study. Body mass, stature and subcutaneous fat thickness for seven sites were measured. Strong (p

  • Prevalence and associated risk factors of work-related muscoskeletal
           disorders among road construction workers in a Nigerian community
    • Authors: A.V. Egwuonwu; C.P. Mbaoma A. Abdullahi
      Abstract: Work-related musculoskeletal disorders (WRMDs) represent a significant occupational problem among road construction workers. This study conducted a prevalence and symptom survey of WRMDs among road construction workers in a Nigerian community and its relationship with risk factors over a twelve month period.The study involved 100 consecutively sampled respondents from construction workers in a Nigerian community. The short version of the Dutch Musculoskeletal questionnaire was used to collect data on demographics, 12 months' prevalence, risk factor and health seeking behavior of respondents. Data were analyzed using descriptive statistics, while spearman rank correlation was used to test correlation at 0.05 α level.A high WRMDs prevalence of 66% rate was reported, with low back (55%) being the most frequently reported body part for symptoms, followed by neck at 45%, while the least prevalent was the left hip/thigh (8%). Significant correlations existed between WRMDs and BMI (p = 0.003), work hours per week (p = 0.018), work exertion (p = 0.004), risk factors (p = 0.001). Logistics regression analysis showed that work organizational factors were significant predictors of WRMDs report of symptoms. Meanwhile, self-medication was the major means adopted by the respondents to alleviate musculoskeletal pain. It is recommended that preventive strategies be adopted to minimize occurrence of WRMDs among these workers in Nigeria.

  • Regression models for predicting anthropometric measurements of students
           needed for ergonomics school furniture design
    • Authors: S.O. Oladapo; O.G. Akanbi
      Abstract: This paper deals with the development of models that make use of some easy-to-measure anthropometric dimensions to predict difficult-to-measure dimensions required for ergonomic design of school furniture. A total of 143 students aged between 16 and 18 years from eight public secondary schools in Ogbomoso, Nigeria participated in the study.In a bid to avoid model complexity, a brute-force search implemented in Adaptive Neuro-Fuzzy Inference System (ANFIS) was employed to select the two most influential of the five input measurements. This search was separately conducted for each of the output measurements. Regression models were developed from the collected anthropometric data. Also, the predictive performance of these models was examined using ANOVA. The best models are the ones with no/non-significant lack of fit and highest coefficient of determinations. Nine out of the 12 developed models exhibit nonlinear relationship. The ANOVA results show that the models satisfactorily predict the difficult-to-measure dimensions from the easily measured ones.

  • Ergonomics and technologies : regulatory compliance in the virtual office
           in South Africa
    • Authors: E.J. Ferreira; E.A. Strydom
      Abstract: This article reports on a study conducted among virtual office employees (n=163) in South Africa. Interest in this topic was triggered by the influence of technological developments that have changed the traditional office scenario. The purpose of the study was to investigate the extent to which policies, regulations and legislation in terms of ergonomics and technologies are put into practice in order to ensure compliance. The absence of policies, regulations and legislation means that no information or training is available for teleworkers that could prevent health and wellness problems. An empirical study was conducted using two structured questionnaires, one for managers and one for employees. The main findings indicate that although a telework policy was in place, not all organisations had formal telework agreements with teleworkers. Arrangements with employees were of an informal nature and the application of policies and regulations was very low. Work-related musculoskeletal disorders may develop if the correct ergonomic principles are not applied. Organisations that allow flexible work arrangements must endeavour to adhere to the relevant Acts and government regulations to ensure that teleworkers work in a safe environment, protecting them from risk factors leading to health and wellness problems.

  • The influence of resistance training on the magnitude of change in the
           resting metabolic rate, program compliance and related obesogenic
           anthropometric parameters in obese and normal-weight female employees
    • Authors: M. Swanepoel; G.L. Strydom
      Abstract: Obesity is a global health concern affecting all walks of life, with alarming prevalence in South African employees. Various companies have already implemented health promotion programs in order to improve employee health; however research focusing on the effect of a resistance training intervention in order to address obesity among employees is scare. Therefore the aim of this study was to determine the influence of resistance training (RT) on the resting metabolic rate (RMR), body mass index (BMI), waist circumference (WC), fat mass (FM), fat-free mass (FFM) and compliance in a group of obese and normal-weight female employees. Seventy-seven pre-menopausal women (25 - 35 years) were recruited and divided into an obese, (BMI ≥ 30) and normal-weight group (BMI ≤ 25.0). Both groups completed a supervised progressive RT program (3 sessions of 40 -50 minutes/week), spread across 12 weeks. Assessments were performed every 4 weeks and results were analysed using the Linear Mixed Model procedure. The normal-weight group (NWG) showed practically significant increases from baseline to 12-weeks in FFM (d = 0.83), RMR (d = 0.58) and exercise compliance (d = 0.58) while the obese group (OG) showed practically significant decreases in WC (d = 0.32) and BMI (d = 0.31). Considering the intra-group % change (baseline to 12-weeks) it is clear that the NWG showed significant increases in RMR (7.0%), FFM (7.8%) and exercise compliance (15.8%) while the OG showed a significant decrease in WC (3.0%) and exercise compliance (9.3%). It seems therefore that the magnitude of change resulting from resistance training (moderate intensity) in NWG differs from that of the OG.

  • Demographic, ergonomic and psychosocial factors affecting work related
           musculoskeletal discomforts in tobacco processing
    • Authors: A. Nag; P. Nag H. Vyas
      Abstract: Work related musculoskeletal disorders have been associated with demographic factors, work stresses and psycho-social stress symptoms. The study aimed to evaluate factors associated with MSDs in different body regions among Indian tobacco processing workers. A group of 450 tobacco processing workers participated in the study. A questionnaire comprising of demographic factors, work related exposures, psycho-social stress and musculoskeletal discomforts was administered. Self-reported prevalence of MSDs, correlation statistics and risk estimates were calculated. Females reported a higher prevalence of discomfort in the upper back, lower back and knees. The ANOVA showed that female workers perceived the work environment and physical activity to be more strenuous compared to their male counterparts. Correlation analyses suggest the influence of different work related aspects on pain in different regions. Physically demanding task situations, high physical activity and poor task clarity were associated with MSDs in both female and male tobacco processing workers. In males, poor job feedback and badly illuminated workspaces, and in females highly specialized job and high skill levels required were associated with MSDs. Psychosocial stress symptoms of workers were found to be associated with pain in different body parts Strategies need to be formulated to improve adverse working conditions to reduce pain related problems and to improve performance in the tobacco processing work.

  • Pesticide-related safety risks among vegetable farmers : a cross sectional
           study
    • Authors: J.L. Lu
      Abstract: This study was conducted to assess the pesticide-related safety risks that Benguet farmers face on a regular basis. Pesticide residue in soil and crops, as well as farmers' knowledge and practices on pesticide were assessed. Methods consisted of survey questionnaire among 38 farmers, and the use of gas chromatography for the analysis of soil and crop samples. All farmers used more than one type of pesticide, most of whom used three types (73.7%). The most common was organophosphate (45.2%). Twelve of the identified pesticide brands were insecticides while the remaining two were fungicides. Twenty-three practiced cocktailing of pesticides (60.5%), mostly to save time. The most common PPE used while spraying pesticides were gas masks, gloves and boots. For the soil and crop samples, 3 soil samples were positive for Chlorpyrifos, two of which exceeded the maximum residue level (MRL). Of the 3 that were positive for Cypermethrin, all exceeded the MRL. Caution must be exercised when handling these potentially harmful pesticides. Proper equipment maintenance, cleaning and storage must be observed to prevent unnecessary pesticide exposure. Pesticide companies and the agricultural branches of the government must work towards adequate user education, focusing on safe handling of pesticides.

      Abstract: This issue of ErgonomicsSA represents an important shift as we proudly introduce "digital object identifiers" (
      DOI s) to our manuscripts. As a member of the African Journals Online (AJOL) network (www.ajol.info), we are able to take advantage of the partnership between AJOL and Cross Ref (www.crossref.org), the independent membership association that "connects users to primary research content". A citation-linking network,
      DOI s reduce the frustration of broken hyperlinks, and ensure a persistent connection to the resource : in this case, your article published in ErgonomicsSA.

  • Perceived exertion and metabolic cost during progressive and randomized
           walking protocols
    • Authors: S.E.H. Davies
      Abstract: The objective of the study was to ascertain whether selected physiological responses and the perception of effort varied during four different walk protocols where speed increased progressively 3, 4, 5, 6, and 7 km.hr-1 (progressive treadmill walk (PTW); and progressive land walk (PLW); or where the participant adjusted to random changes of speed e.g. 6, 4, 7, 3, and 5 km.hr-1 during a randomized treadmill walk (RTW); and a randomized land walk (RLW). Mean stature and mass of the seven participants was 1.75m and 70kg respectively, with a mean body fat of 15%. Metabolic measures included heart rate, relative oxygen uptake, ventilation, respiration frequency, which increased in a linear fashion up to 6 km.hr-1, however at 7 km.hr-1 there was a significant increase in metabolic response notably during the PLW, and to a similar, although lesser extent in RLW, probably as a consequence of the loss of kinetic energy when turning at each cone in order to maintain the speed during each shuttle. Respiration frequency appeared to be a more sensitive indicator of physical exertion, exhibiting a rapid elevation at 6 km.hr-1. The perception of effort during each mode and at each speed was largely congruent during each walk protocol.

  • Ergonomic chair explorative intervention study : effect on chronic upper
           quadrant musculoskeletal dysfunction, disability and productivity in
           female computer workers
    • Authors: M.C. Wills; Q.A. Louw
      Abstract: Persistent upper quadrant musculoskeletal pain and disability are common in female computer workers; they are associated with a complex relationship between individual, work-related and psychosocial factors. Upper quadrant musculoskeletal dysfunction has been associated with reduced work performance. Although there is lack of evidence for an adjustable office chair on computer workers' upper quadrant dysfunction and productivity, an adjustable office chair may provide a platform to change the computer workstation set-up and thereby have an effect on upper quadrant musculoskeletal structures. The aim of this two single-subject (n=1) explorative study was to determine whether an adjustable ergonomic office chair was associated with self-reported improvement in chronic upper quadrant musculoskeletal dysfunction and work productivity among female computer workers, compared to a less adjustable ergonomic office chair. Results found a clinically meaningful short-term reduction in both participants' self-reported upper quadrant pain and perceived muscle tension. One participant's results showed a clinically meaningful reduction in self-reported neck disability and work impairment, resulting from the upper quadrant musculoskeletal dysfunction. The other participants' baseline values for both neck disability and work impairment were too low for a meaningful comparison. Study findings indicated that a height-adjustable ergonomic office chair reduced upper quadrant musculoskeletal dysfunction in two female computer workers. This explorative study forms the foundation for further studies that aim to make office chair recommendations for female computer workers to reduce UQ musculoskeletal dysfunction.

  • The role of ergonomics in sustainable agricultural development in Nigeria
    • Authors: O.F. Obi
      Abstract: Nigeria is mainly an agrarian society, with the majority of her rural populace involved in agriculture. Agricultural working conditions in Nigeria are extremely difficult due to severe environmental conditions, long working hours, strenuous work and the use of simple farm tools. The extreme working conditions can lead to the development of Musculoskeletal Disorders (MSDs), which have been recognized as the most prevalent of all safety issues in agriculture. This paper reviews the role of ergonomics on sustainable agricultural development in Nigeria. Agriculture plays a key role in the Nigerian economy and hence the need for sustained development within the sector. Ergonomic intervention in Nigeria was identified as a key driver for sustainable development while fostering safety and comfort of agricultural workers. Mechanization alone is not sufficient to achieve the desired development in agriculture due to the high cost associated with it, but with improvement on existing simple tools and modification of existing machines based on ergonomic considerations, sustainable development can be attained. The awareness of ergonomics among stakeholders in the sector and the impact of musculoskeletal disorders on Nigerian agricultural workers were reviewed. The benefits accruable from ergonomic intervention in Nigerian agriculture were also identified.

  • Evaluation of work related musculoskeletal disorder and postural stress
           among female potato cultivators in West Bengal, India
    • Authors: A. Pal; S. De, P. Sengupta, P. Maity P.C. Dhara
      Abstract: Apart from cereal production (rice, wheat, etc.) agricultural labourers are engaged in different vegetable cultivations in West Bengal, India, of which potato cultivation is one of the more important vegetable cultivations. Potato cultivation requires manual work and workers are exposed to extreme postural stresses. The present study was aimed at evaluating the musculoskeletal disorder and postural stress experienced by female workers engaged in potato cultivation. The study was conducted on 155 female cultivators in different districts of West Bengal state (India). A modified Nordic Questionnaire and Body Part Discomfort Scale were applied to identify musculoskeletal disorders (MSDs) in different body parts. The postural stress was analyzed by four methods, viz. OVAKO Working Postures Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), and Quick Exposure Check (QEC). From the results it was revealed that the prevalence of MSDs among the female workers was very high and the most affected areas were the back and upper extremities. Stooping and squatting postures were the dominating postures in potato cultivation jobs. Postural analysis indicated that during potato harvesting the workers were subjected to greater postural stress than that of other tasks. Postural stress might be the reason for the occurrence of MSDs. Thus, immediate ergonomic interventions are needed to reduce work stress of the women potato cultivators by correcting awkward postures.
