Approach Towards Design of Functional Sportswear for Improved Human Performance

Abstract
Contemporary design and production of textile and clothing is focused on development of products with innovative characteristics and hi-tech functionalization for improved human performance. Therefore, an important innovation area is the R&D of specifically engineered materials and assemblies. The research is directed towards delivery of a pre-defined performance or functionality to the user, over and above its normal functions. This paper gives review of the state-of-the-art research in the area of functional sportswear design and discusses niches for the innovations beyond. The experimental part covers evaluations within three crucial segments, i.e. thermophysiological comfort of material observed trough the permeability index, thermophysiological comfort of single layered sportswear observed using thermal camera and sensorial comfort of single layered sportswear material. The test results are supported by regression models. Throughout the discussion and conclusion is outlined the need for comprehensive and systematic approach towards design and further evaluation of sportswear in order to enhance and augment body functions.

Functional and Subjective Assessment of Spinal Exoskeletons: From Development of Battery of Tests to Experiments with Low Back Pain Patients

Abstract
Spinal exoskeletons have recently emerged as a potential tool to prevent and treat low back pain (LBP) in workers that are involved in heavy load handing and other demanding jobs. However, the widespread use of these devices is still limited. Notably, discomfort and hindrance of movement is often reported by the end-users. Therefore, there is an increasing interest to explore functional and subjective aspect of exoskeleton use. In this paper, we will present a novel battery of tests that was designed to comprehensively assess the effects of spinal exoskeletons on functional performance, discomfort and task difficulty. Next, we provide evidence that specific populations, such as LBP patients, may respond differently to the use of exoskeletons, which should be considered during design and development. Finally, we briefly summarize the findings from a study that investigated the effects of one of the state-of-the-art exoskeletons, by using the previously developed functional test battery.

Skidder Operator Vibration Exposure

Abstract
The exposure of workers to vibration is expressed as energy equivalent A(8), which is determined by the procedure clearly described in the international standard ISO 5349-1-2001. A(8) is a value that depends not only on the vibration level in certain operating procedures, but also on the duration of exposure. Research was conducted on Ecotrac 120 V and Ecotrac 140 V, the most used skidders in Croatian forestry. Vibration on the steering wheel and seat of the skidders was measured by vibrometer with triaxial accelerometer. Measurements were performed at three characteristic engine operating modes: idling, at maximum torque and full throttle. Daily exposure to vibration of a skidder operator A(8) is calculated based on structural data of daily working times in different working conditions as well as distribution of three characteristic engine operating modes of effective time. The results show differences in vibration levels between different types of tractors and working conditions. The research was carried out within the project “Development of hybrid skidder—HiSkid” co-financed by European Regional Fund in the scope of European Union Operational Program “Competitiveness and Cohesion” 2014–2020 (2014HR16M1OP00-1.2).

A Preliminary Study of the Possible Impact of Non-related Driving Tasks on the Car Driver’s Performance Using Glance-Based Measures

Abstract
In road traffic, the knowledge of the impact of drivers’ distraction on the performance is critical to address the safety incidents and to reduce the number of road accidents. Previous research has mostly investigated the impact of different types of driver distraction on the driver’s performance. This preliminary research will explore the possible impact of simultaneous interaction of two or more types of distraction inside a vehicle on the driver’s performance using the driver’s glance behavior. A possible impact on the driver’s performance will be analysed by comparing the driver’s gaze parameters for different driver activities imposed by the scenario in relation to the baseline driving mode. The drivers will perform real-world driving scenarios doing a non-related driving task such as smoking, consuming soft drinks, and using a mobile phone fixed on a stand under the rearview mirror. Two scenarios have been used to evaluate mobile phone use: casual video call conversation and video call conversation while solving a cognitive task. The drivers’ glance parameters such as glance duration, gaze direction, percent of gaze on road center, and others will be assessed from video data on the sample of three drivers. This preliminary study will be a small part of a larger-scale research planned for the near future.

Achilles Tendon Load at Squatting Working Position

Abstract
Workers often take squatting positions during work, some stay in this position for a short time, and some for longer, and often have an additional load in their hands (tools, instruments, loads). The aim of the study was to determine the load that occurs in the Achilles tendon while squatting. The Achilles tendon is one of the largest and strongest tendons, but too much stress can cause pain, swelling, tendinopathy, tendon damage or even rupture. A mathematical model based on the statics of rigid bodies was set up to determine the force in the Achilles tendon. Experimental part of the study was conducted using the Elite system and the Zebris platform. The loads of the Achilles tendon when squatting on the full foot and on the toes were determined. The determined stress values in the tendon are smaller than the values at which tendon rupture occurs, but still large values that can cause pain and pathological processes.

Ergonomic Assessment with a Convolutional Neural Network. A Case Study with OWAS

Abstract
The ergonomic assessment of workplaces is key to optimize work stations and tasks, and in some legal frameworks it is mandatory for companies to perform such evaluations. Currently, most of the evaluations are carried out by means of observational methods like REBA, OWAS, RULA, etc. The usual procedure to apply those methods consists of recording the worker in a normal work day, and then analyze postures, joint angles and movements by visual inspection. That is a tedious and slow process, which is very dependent on the evaluator’s experience. Artificial vision can help to analyze and objectify the video in a few minutes. The objective of this work is the development of an ergonomic assessment method based on artificial vision and a convolutional neural networks, in order to reduce the time of analysis of the videos used in ergonomic evaluations. For this purpose, the neural network used (Simple Pose network) and its application to the analysis of postures is presented, and then a use case is presented, evaluating a workplace with the OWAS methodology.

Space, Time and Ergonomic Assessment of Order Picking Using Horizontal Carousel

Abstract
The efficiency of order picking operations can be enhanced by different automated storage/retrieval systems (AS/RS) based on the “part-to-picker” principle. One such system is a horizontal carousel, a rotating rack that delivers parts to the operator. Apart from space and time reduction related benefits, horizontal carousels are often marketed as well as better ergonomic systems compared to traditional shelving rack systems. However, not many papers deal with a quantitative comparison of horizontal carousels with shelving systems that are much more used for small parts order picking. Especially there is a lack of papers analyzing ergonomics of horizontal carousels. In this paper, horizontal carousels are briefly presented, followed by methods to compare horizontal carousels with shelving systems in terms of space, time and ergonomics. For ergonomic assessment, a method of energy expenditure calculation is used. Presented methods can serve as tools for managers for additional justification of horizontal carousel’s implementation.

Modified NIOSH Lifting Equation with MATLAB

Abstract
Work-related musculoskeletal diseases despite decades of efforts, represent a leading workplace risk. The NIOSH modified lifting equation, available in various forms and platform, can be used to assess the risk from manual material handling. While assessing just a few lifts per shift or homogeneous lifting situations is relatively simple; however, in a mixed, high-frequency lifting situation, the risk assessment involves significant data collection and requires complex data processing. In this paper, we present the MATLAB processing of manual handling data retrieved from a production program through an assembly line job as an example. We show the transfer functions for each risk factor and the importance of accurate input data and evaluate their impact on the ultimate risk.

New Proposals for Improvement of Train Driving Support Systems Performances

Abstract
The modern railway traffic management practice increasingly implies application and development of train driving support systems. The focus of research in this area is on the impact of these systems on the efficiency of railway transport, mostly through the quality and optimization of railway timetables realization and energy efficient train driving. In this paper, an overview of the application of train driver support systems is given and their impact on the efficiency of railway traffic is analyzed. The results of the analysis showed some advantages of train driving support system application related to quality of timetable realization and energy efficient train driving but also marked possible problems related to increase of train driver workload and hence decrease of railway traffic safety. Based on this analysis, new train driving support systems functions for improvement of railway traffic efficiency are proposed. Additionally, a new proposal of systems interface design performance by using human voice for advice information transmission as an addition to displaying information on the monitor for the purpose of railway traffic safety improvement which can be reduced by increase of train driver workload and focus distraction due to application of train driving support system is suggested.

3D Printing Technologies for Clothing Industry: A Review

Abstract
3D printing represents a process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material. It brings a digital object into its physical form by adding layer by layer of materials. This technology is represented in a large number of different production sectors, especially in the modern aviation industry, construction industry, clothing industry, automotive industry, shipbuilding, medicine, dentistry, film industry and various design and artistic fields. The quality implementation of 3D printing technologies in each of the mentioned branches of production is important. The earliest 3D printing technologies first became visible in the late 1980s, and then they were called Rapid Prototyping (RP) technologies. This is because the processes were originally conceived as a fast and more cost-effective method for creating various prototypes for product development within industry. The paper presents the development of 3D printing technology as well as the opportunities it provides for the clothing and fashion industry.

Research of Working Postures in the Technological Sewing Process Using the REBA Method

Abstract
The characteristics of the work in the technological sewing process depend on the type and character of the workpiece, the type of the sewing machine used to perform the technological operation, as well as on the training and skills of the worker. In the technological sewing process, the work is performed in a sitting position at the sewing machine, whereby the worker performs hand and/or machine-hand technological suboperations. During the performing of technological operations, the worker uses her hands and torso to handle the workpiece, and the feet to operate the sewing machine pedal at short intervals with continuous repetition throughout the work shift, subjecting the worker to stress. The paper analyses the working position at nine workplaces in the technological sewing process using the REBA method (Rapid Entire Body Assessment). The analysis of the results showed that there is workload (medium or high risk) at all workplaces that requires workplace adaptation in the form of workplace redesign. The redesign of workplaces involves adapting the dimensions of the workplace to the worker’s height and determining a more favourable working method that achieves a lower workload.

Analysis of Working Conditions and Modeling of Activity Algorithms for Contact-Center Operators

Abstract
The article examines the issues of ensuring the reliability of the activities of information processing operators who work in contact centers. A study of factors that reduce the effectiveness of call center operators was carried out. A method of formalized description of operators’ activities based on functional networks of professor A. Gubinsky is proposed. The use of this method makes it possible to assess reliability taking into account the structure of the operators’ activities and working conditions. A model is proposed to justify the number of operators, design the structure of activities and working conditions. The study can be useful to justify the feasibility of improving ergonomics in contact centers of commercial and government organizations.

Portuguese Firefighters’ Anthropometrics: Pilot Study Results

Abstract
Personal protective equipment is of paramount importance in aiding and protecting firefighters against hazardous conditions. Personal protective equipment should be compatible to firefighters’ body dimensions. However, the lack of updated anthropometric data for this specific occupational group can lead to ill-fitting equipment, compromising work performance and the level of protection. To understand if Portuguese firefighters’ protective equipment is adjusted to their anthropometrics a study designated as Size FF Portugal is currently underway. A pilot study was conducted in a fire brigade located in the North of Portugal aiming to collect preliminary anthropometric data. Thirty-two male firefighters participated in the pilot study. This paper contrasts some preliminary anthropometric data of Portuguese firefighters with an anthropometric database of U.S. firefighters. The results show statistically significant differences between the stature and weight of Portuguese and U.S. firefighters. Conversely, crotch height and calf circumference measurements were not statistically different when comparing firefighters of both countries. Final considerations regarding the study limitations are presented.

Embedding Function Icons into QR Codes

Abstract
This paper proposes an approach to produce high-quality visual QR codes introducing the concept of function icons (FI)—images embedded into QR code. FI design resembled abstract symbols, like identifiable and memorable smartphone app icons or logos. The embedding visually points to the function of a QR code and therefore is more attractive to the end-user than the traditional QR code. Also, the FI perceptual simplicity increases users’ navigation and accessibility over different media. For optimization, the proposed FI design was altered by pixel size, color, and luminance modification, without affecting the decoding reliably. The contrast between dark and light modules of the FI color tone was determined to a minimum of 70% to enable the code reader’s conversion of the image to grayscale and then segmentation it into black and white pixels. The eye-tracking research on QR codes with implemented icons confirmed the subjective attractiveness evaluation. The technical quality of the proposed design was verified with a QR code readability test. Since more than 95% of examinees successfully recognized the content behind a QR code before scanning and evaluated the design as more attractive than a traditional solution, we demonstrated that our approach produces high-quality results for a variety of FI designs.

Suitability of School Furniture and Correlation with Pain Prevalence Among Slovenian 6th to 9th Graders

Abstract
School furniture has been recognised as a potential risk factor for musculoskeletal pain among primary school pupils. The aim of this study was to assess student-furniture mismatch and to determine the association between unsuitable school furniture and musculoskeletal pain among Slovenian pupils. Firstly, pupils’ body dimensions were measured, and student-furniture mismatch was calculated. Secondly, pain prevalence was assessed using adjusted Nordic questionnaire. A total of 68 pupils from 6th to 9th grade (age 12 ± 1, 44% males) participated in the study. Seat height was unsuitable for 90% of pupils and desk height for 82% of pupils. One third of pupils reported knee pain and more than one fifth of pupils reported neck, shoulder, upper, and lower back pain. Logistic regression revealed no significant impact of school furniture on pain occurrence among pupils. However, the data indicated upper back pain might be associated with unsuitable backrest. The results showed that school furniture in Slovenian primary school is unsuitable for most pupils. The association between furniture and pupils’ musculoskeletal pain needs further investigation. Redesign of school furniture is desired, and the anthropometric data obtained could be considered when designing new school furniture.

Burnout and Workload Among Health Care Workers in Bulgaria

Abstract
This study aimed to estimate the relationship between workload and burnout syndrome among healthcare professionals working in training or non-training healthcare organizations in Bulgaria. The study was conducted using the web-based Bulgarian Version of the Boyko’s Burnout Inventory, which contains 84 statements grouped in 12 symptoms and 3 phases, and questions related to the weekly workload. The data were exported directly to SPSS 17.0 statistical software and analyzed with descriptive statistics and Spearman’s correlation coefficient rs. The level of significance of 5% probability (p < 0.05) was adopted. Based on the responses to the Boyko’s Inventory 29.0% of the respondents had a high level of emotional exhaustion, 51.6% had a high level of resistance, and 31.50% had a high level of strain. The high level of burnout was found among 27.4%. The average weekly working hours for all respondents were 43.78 ± 16.51 h. For specialists who have been diagnosed with burnout, the average weekly working time was 48.47 ± 13.72 h. For those who did not receive a positive diagnosis, the average weekly duty time was 37.72 ± 15.22 h. There were average correlations between the level of burnout and the weekly working hours (rs = 0.286; p = 0.001).

Proposal of an Ergonomic Interface for Supervision and Control of an Automated Shunting Device

Abstract
In rail freight transport, certain processes require shunting activities to form or dissolve freight trains. In the present form, this requires shunting staff to carry out these physically demanding tasks. In spite of all precautions, accidents at work occur during such activities, which can be accompanied by serious injuries or even death. One approach to prevent such accidents will be the use of automated shunting units and an automatic uncoupler. In this paper the process of an automated system is sketched. It describes the responsibilities relating to the controlling and supervision staff of the process. It is shown how the flow of information between the parties involved can take place. Results of this research show how the proposal of an ergonomic interface for supervision and control of an automated shunting device can be sensibly integrated into the existing operation of marshalling yards. The proposal offers improvement of railway staff safety through reducing dangerous operating procedures and help to reduce the future lack of available staff.
