Authors: Kurt Fatih , Eröz Recep , Doğan Mustafa
Published: February 2022

Drug-Resistant Epilepsy is the continuation of seizures despite administering two tolerable antiepileptic drugs at the appropriate dose and time, which are selected according to the type of seizure. Growth retardation, focal neurological findings, organic brain lesions, specific EEG disorders, and epilepsy in the family are risk factors for resistant epilepsy.

Tuberous sclerosis is a multisystemic and autosomal dominant genetic disease with hamartomas in many organs such as the skin, central nervous system, kidney, and lungs. Brain hamartomas and other central nervous system lesions cause resistant epilepsy in tuberous sclerosis.

In this article, we present a 16-year-old patient with tuberous sclerosis who was followed up with the diagnosis of resistant epilepsy, despite typical physical examination findings. This research emphasised that tuberous sclerosis should be kept in mind in the aetiology of resistant epilepsy and how important physical examination is.

Published: February 2022

This paper aims to apply an Adaptive Network-based Fuzzy Inference System (ANFIS) controller in a DC-link voltage regulator to decrease the power fluctuation for enhancing the performance of the grid-tie inverter for a small-scale rooftop solar Photovoltaic (PV) system. For tracking Maximum Power Point (MPP), a Perturb and Observe (P&O) algorithm was presented. To demonstrate the effectiveness of the proposed controllers for a small-scale 5 kWp rooftop solar PV system, several time-domain simulation results under a three-phase short-circuit fault that happened at a grid-tie inverter system was systematically performed by employing Matlab/ Simulink toolbox. On the basis of the simulation results, it is obvious that the proposed P&O algorithm for MPP tracking and the designed ANFIS controller for DC-link voltage regulator of the grid-tie inverter shows better performance to reduce overshoot and settling time in transient responses of the studied small-scale 5 kW grid-tie rooftop solar PV inverter under the most severe operating condition.
Design and Optimization of a Large-Stroke Compliant Constant-Torque Mechanism
Authors: Phan Thanh Vu , Pham Huy-Tuan
Published: February 2022

Compliant constant-torque mechanism (CTM) can produce an output torque that does not change within a prescribed input rotation range. This stability is maintained regardless of complicated sensorized control systems. Owing to the monolithic nature of the compliant mechanism, the device is more compact, lightweight, and portable, which is favorable to human joint rehabilitative devices or mobility-assisting devices. However, before approaching the stable range, the mechanism has to undergo a pre-loading range which usually accounts for one-third of the entire operational journey. In addition, the deformation of flexible segments is restricted due to the yield strength of the materials. This limited working range hampers other potential applications of compliant CTMs. This paper presents a novel design of a compliant 2-stage CTM with long-stroke by using serially connected curved beams that deform sequentially. The design process is implemented via a shape optimization scheme using genetic algorithm. Finite element analysis is used to characterize the constant-torque behavior of the CTM under static loading. A general design formulation is also proposed to synthesize this special kind of compliant mechanism. The results show that this CTM gets the stable torque range from 300 to 1100 over two stages with the deviation less than 4.3%.

L’ART POST-CATASTROPHE : UN TÉMOIN ACTIVISTE
Authors: Abou Khalil Michel
Published: February 2022

Le Liban, un pays riche artistiquement et intellectuellement, est la scène par excellence d’un enchainement de catastrophes depuis sa naissance jusqu’à nos jours. L’explosion du port de Beyrouth le 4 Août 2020 en constitue l’ultime épisode et peut-être le plus dramatique de tous. Un phénomène inédit s’est révélé suite à cette tragédie sans précédent : la scène culturelle s’est immédiatement mobilisée sans passer par une étape mnésique post catastrophe comme c’est en général le cas après un désastre. Que s’est-il passé ? Pourquoi une telle urgence ? Comment les artistes ont-ils utilisé leur créativité pour exprimer l’indicible, le penser, en témoigner, sensibiliser et commencer un processus de guérison des blessures traumatiques ? Afin de répondre à cette problématique, nous allons explorer une création post-catastrophe relevant des arts visuels. L’exposition L'Art Blessé présentée du 16 décembre 2020 au 16 janvier 2021 à La Villa Audi, propose une série d’oeuvres sinistrées provenant de collections privées beyrouthines. Les dommages subis vont engendrer une mise en abyme où les traces se métamorphosent en oeuvre dans l’oeuvre. La scénographie de l’architecte Jean Louis Mainguy, accompagnée de poèmes et de musique, est ancrée dans l’interdisciplinarité.

Published: February 2022

Workers musculoskeletal occupational injury is closely related to worker's job status and posture. Short-term or long-term excessive exercise and poor posture may cause temporary or permanent musculoskeletal hazards, affect workers physical health. OWAS is a comomly used evaluation tool for working postures disorders assessment. It requires an ergonomics expert to evaluate through the musculoskeletal disorders risk table. Using OWAS evaluation system not only can provide injury prevention but also can calculate various influence of injury. However, this evaluation requires an expert to monitor an operator for a long period of time, which is tedious and high cost. This objective of this paper is to build an automated musculoskeletal disorders assessment system using the Microsoft Kinect with the OWAS system scuh that the related working postures disorders can be easily explored. The proposed system uses Kinect skeleton tracking system to collect worker’s skeleton information including head, hands, wrists, elbows, shoulders, trunk, hips, knees and foot (20 knots). By means of a self-developed algorithm, the system can automatically record, analyze, and assesse the joint positions and angles between joints such that the posture of a worker can be identified based on OWAS coding system. The proposed system was implemented using C# under Window 7 platform with Microsoft Kinect SDK. A set of experiments was conducted to verify and validate the Kinect skeleton tracking system and self-developed algorithms. The experimental results show that the proposed system effectively recorded and estimated the posture of workers such that manpower and resources are saved and the potential of job hazard can be explored.

Authors: Bretschneider-Hagemes Michael
Published: February 2022

The standard ISO 16673 addresses the use of in-vehicle information systems (IVIS) and the measurement of the associated visual demand. The proposed measuring method investigates secondary tasks at the driver’s workplace in terms of their visual demand. The contributory factors and hence levers for prevention work are the complexity of the task, the usability of the man-machine interface (MMI) with its retroactive effects on task complexity, and device visibility (clear identification of symbols) and position. These factors are rendered measurable in their cumulative visual effect by the occlusion method so that valid and practical recommendations can be made.

Published: February 2022

Recently, incidents and disasters occurring in home as well as abroad influence whole industrial society not just limited in business places or districts. If safety management system of business is broken, then an incident occurs. This brings out a huge loss at the scene of an incident and other businesses. And then, delayed and passive reaction to this incident may be expanded to a national disaster. A state of emergency caused by these disasters threatens countries and public's safety in addition to company's loss, and it can encourage social and financial anxiety worldwide. If BCMS(Business Continuity Management System)’s, which has recently been adopted as a social safety system, is established in a general place of business, overlap and collision are inevitable in many sides. And it will make an overlapped organization that makes confusion in company by a cost of management. To avoid these overlap and collision, for making better OH&SMS (Occupational Health and Safety Management System), companies need to construct a unified business system after adding applicable requirements in business place. And then we can minimize confusions and burdens in company, and operate integrated system including BCMS. This study suggests using HSSMS (Health, Safety and Security Management System) which is KOSHA 18001 - nowadays many companies are used in KOREA - utilized by BCMS. If company adopts this HSSMS(Health, Safety and Security Management System), following positive effects can be expected.1) HSSMS makes it possible for company's OH&SMS to unify with BCM systems and to be continual improvement and operation.2) Because HSSMS makes OH&SMS communicate with national BCMS, it helps constructing and operating BCMS being cooperated by the public and civil sector.3) OH&SMS and BCMS make it easier to decrease accident rate, enhance working environment, increase productivity, hold a dominant position in internal and external market, preoccupy the appearance of global standard, and respond the voluntary restraints of market.

Published: February 2022

Sewing machine workers have high prevalence of WMSDs in neck-shoulder, wrists and lower back region. It is known that occupational physical exercises programs have positive benefits regarding complaints and absenteeism due to musculoskeletal symptoms. Therefore, the aims of this study were to evaluate ergonomic, musculoskeletal and psychosocial conditions of workers from an upholstery and sewing sector, and investigate the effectiveness of a physical exercise program applied at the occupational environment. Fifteen workers (44.5 ± 8.8 years old) took part of the study. Musculoskeletal symptoms were evaluated through the Nordic Musculoskeletal Questionnaire (NMQ), Roland–Morris Disability Questionnaire (RDQ) and a standardized physical examination. Psychosocial indicators were evaluated from the Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES), while the Ergonomic Workplace Analysis (EWA) protocol was applied to assess workplace conditions. The physical exercise program was applied twice a week for 30 minutes, during 12 weeks. It was composed by warm-up, strengthening and stretching exercises. A significant reduction on musculoskeletal symptoms were observed for wrists/hands and lumbar spine considering results from the NMQ, and for all body regions assessed through the physical examination, except for elbows. Moreover, psychosocial indicators have shown significant improvement. These benefits increase workability and promote better quality of life to the workers, and can be reproduced in other workplaces.

Authors: Taïar Redha
Published: February 2022

The aim of our study is to increase the comfort of users at work by studying the balance and by minimizing the joint stresses. Studying the upright position, the adjusting of his segments to maintain the good balance and decreasing muscular problems are the main elements to highlight in order to improve the everyday (working) life of users. Based on the optimization of new materials, the project consists in validating prototypes destined to improve ergonomics at work and to optimize the comfort of users (new anti-fatigue mats Notrax®). Without mats our results showed a dysfunction balance of the worker which can cause pathologies or repetitiveness and other work constraining factors which can accelerate the process. The distribution of foot pressure obtained (30% and 70%) of the weight of the body is mainly on the right side. This imbalance is very harmful for the human body. With Mats we observed in working situations where people make small movements constantly, the anti-fatigue mats that we tested good properties that give a muscular-skeletal comfort in upright working positions. This can be verified by the constancy of the force evolution curve during the movement.
Suitable Interhandle Distance on a Roll Box Pallet during Turning Task
Authors: Ohnishia Akihiro , Takanokurab Masato , Sugamaa Atsushi
Published: February 2022

Roll box pallets (RBPs) are manual material-handling equipment with four swivel wheels, used in Japan. Although they are widely used in almost all industries, many RBP-related operator accidents have occurred in the transportation industry, usually involving injuries to the hands or feet. To decrease the likelihood of hand injuries, it is important to install special handles situated toward the inside of the frames. This study aimed to determine a suitable RBP interhandle distance for turning movements. Six healthy young males were asked to move the RBP (height, 170 cm; depth, 80 cm; width, 60 cm) by 90° at a normal speed using handles with four different interhandle distances (40, 50, 60, and 80 cm) and two loading conditions (0 and 50 kg) for approximately 1.4 m. A three-axis accelerometer attached to the lower part of the RBP was used to measure motion. Then maximum combined values of the longitudinal and lateral directions (horizontal plane) and maximum upward values were analyzed during the initial response phase. Operability was evaluated by the acceleration data, handling process duration, and subjective evaluation. Operating duration was approximately 5 s. It was longer for the 50-kg loading condition for all interhandle distances, and significant differences between interhandle distances were not observed with both loads; however, the duration tended to be shorter with wider interhandle distances in the 50-kg loading condition. Subjective evaluation ratings were similar in RBP movement durations. The maximal acceleration on the horizontal plane showed varied with different interhandle distances, probably because horizontal acceleration tends to affect RBP movement in tasks combining lateral movement and rotation. In contrast, maximum upward acceleration increased with increased loads, but was not affected by an increase in the interhandle distance. This indicates that the upward acceleration probably corresponded to the lifting of the handles while applying lateral force. The results suggest that a wider interhandle distance, e.g., 80 cm, would be suitable for RBP movements, including lateral movement and rotation.

Published: February 2022

Forceful tendon exertions while gripping hand tools may be one of the factors leading to the development of work-related musculoskeletal disorders (WRSMDs). Estimated tendon forces from biomechanical hand models are unreliable and need to be validated. A novel neuromuscular grip simulator using a cadaver forearm was developed consisting of 1) an aluminum frame supporting the specimen, 2) a motion-delivery unit with stepper motors applying force to the FDP and FDS tendons, 3) a data acquisition unit for force transducers, 4) a camera system measuring finger joint angles, and 5) an operating system to control the complete simulator. Of special necessity were an adjustable fixation system, the Wristjack and the use of freeze clamps with liquid nitrogen to insure a tight bond between the slippery tendons and the force delivery system. Key experimental factors varied were five different diameter handles and the ratio of FDP/FDS tendon forces. The results on two specimens showed an inverse relationship of handle size and grip force, with the smallest handle size of 30 mm being best. A 3:2 ratio (40% FDS) provided the best efficiency and the largest gripping. Internal tendon averaged 6.2 times the external forces,matching the biomechanical model predictions of Kong, 2004. 72% of the power grip was concentrated on the distal phalanges. Overall, this novel simulator served well for understanding internal tendon forces.

Published: February 2022

The human foot is a complex biomechanical structure, which is consist of 26 bones, numerous muscles, ligaments, joints, nerves, arteries, veins and other soft tissues, is contributing the overall shape of the foot, and is mainly helping to bear the entire body weight, and static and dynamic motions of the foot. The foot has various dynamic motions such as dorsiflexion, plantar flexion, inversion, and eversion, abduction and adduction. The foot shape, structure, functions and motions will vary from one person to another person due to its own morphological structure. A footwear designer is necessary to know about these structures and functions of the foot to design and construct the footwear with comfort and fit. Conventional methods such as anthropometers, calipers, and tapes are used to get the anthropometric data to design the custom-made footwear. Recently, 3D scanning of the foot has been used to get the accurate anthropometric measurement foot data to design the good-fitting footwear. However, there are very few studies reported about Kinect for foot measurement. It is difficult to predict the changes of the foot inner structures during the various functional position of the foot. Therefore, this study tries to develop the 3D functional foot model with using different high heel position. It also considers the effect of land marking error. A result of this study is essential for the design of better fitting and comfortable footwear.

Published: February 2022

Work-related musculoskeletal disorders are common and costly, particularly among home healthcare workers. These workers are a particularly interesting occupational group because of growth of the home healthcare industry and specific patient transfer exposures. This cross-sectional study of 883 home healthcare workers from 17 agencies evaluated self-reported personal and occupational factors related to 1-year period prevalence of neck pain. One-year prevalence odds ratios (PORs) were calculated by separately comparing WMSDs in aides and nurses to office workers/therapists. Multiple logistic regression models were constructed for WMSDs. For neck pain the potential confounders included in the logistic regression models were: age, gender, smoking history (calculated in pack years), body mass index (BMI), time spent performing aerobic exercises, personal psychosocial factors, work related psychosocial factors, miles traveled in an automobile during an average day, and the degree to which the HHCW felt rushed or hurried traveling from patient to patient. Many occupational and non-occupational factors were statistically significantly related to 1-year period prevalence of neck pain with prevalence odds ratios for home healthcare aides at 1.99 after adjustment for above factors. Nurses had higher statistically significant risk estimates at 2.17. Both home healthcare aides and nurses are at increased risk for neck pain.
Worker Fatigue. An Overview of Subjective and Objective Methods of Measurement
Authors: Kuliński Marcin , Koszela-Kulińska Joanna , Jach Katarzyna
Published: February 2022

Fatigue, as a psychophysiological state, is a normal human condition experienced as a result of mental or physical activity that consumes one's biological resources. In order to relieve its symptoms and to restore human's ability to continue work, a return to a fresh, relaxed state is required. It is usually obtained by an adequate amount of rest and/or sleep, but under the presence of some disadvantageous factors, such as too hot or too cold microclimate, high levels of noise at a workplace, work overload, psychological stress, lack of motivation, and others, e.g., family or health-related problems, this needed amount of rest simply may not fit into a normal 24-hour cycle of activity, resulting in the fatigue built-up. A fatigued worker becomes prone to performance deterioration, loss of concentration, misjudgment of his/her environmental safety, hazardous behaviors, anxiety and sleepiness. Therefore, worker's fatigue management is essential for improving productivity and quality of work, as well as for building worker's satisfaction, motivation and overall wellbeing. To supervise fatigue, appropriate tools for its measurement are required. This paper presents an overview of existing methods of fatigue measurement, including psychological (self-reports and questionnaires), physiological (i.e., changes in various body functions), and performance related (e.g., reaction time, sensory abilities) ones.

The work of professional instrumentalists requires a great effort and many hours of daily practice. The musculoskeletal system is under a considerable strain, which is often excessive and taking the form of overload. In the specialist literature conditions of this type are referred to as "playing-related musculoskeletal disorders (PRMDs)" of instrumental musicians. In the violinists these dysfunctions or diseases affect mostly the areas of the right shoulder and elbow, left hand and fingers, and cervical spine. This article presents some biomechanical methods of measuring the movement of violinists during the play. The study was performed using exoskeleton Motion Capture system. The authors present also the electromyography as a method for evaluating muscle tension. It enables the reference to ergonomic standards, applied to repetitive or monotype physical activity, and makes it possible to compare the involvement of individual muscles during play. Additionally, interesting observations concerning an instrumentalist’s body at work can be made using thermal imaging equipment. This method of measurement reflects physiological processes that accompany the effort. Research methods used in the article may help to determine the etiology of the most common ailments in string instrumentalists, provide accurate and objective biomechanical evaluation of the motion loads of musicians and may also pave the way for an effective prevention of diseases in this professional group.

Published: February 2022

The progress in data processing and transmission technology over the last 25 years has revolutionized the concept of office work which prevailed in the whole 20th century. Thanks to a possibility of cooperating in virtual teams it is possible nowadays to work in any place at any time provided there is an access to the global digital network. ​Such a high level of flexibility may, however, cause significant difficulties. They may include first of all a worse flow of information within the company. It is connected with fewer direct, informal, interpersonal contacts which are replaced by remote contact. ​ Another serious difficulty is the presence of so called logistic stress whose generation is connected with the difficulty in juggling professional and private life, which may be especially difficult for people working irregular hours and in various locations. Those issues may negatively affect both the efficiency and the satisfaction level of white-collar workers. ​The objective of this article is to demonstrate a possibility of preventing such problems by conscious designing of office space, taking into account both the need of informal contacts and the necessity of equipping the office building with a number of facilities which might cause the reduction of the logistic stress. ​With the example of an office building erected 30 years ago it will be demonstrated how it is possible to transform the old building with a corridor layout into a building with a flexible layout better suited for today’s needs.
Democratic Culture Paradigm for Organizational Management and Leadership Strategies - The Company Democracy Model
Authors: Markopoulosa Evangelos , Vanharantab Hannu
Published: February 2022

Democracy is one of the most powerful words in the world. A word that indicates justice, equality, development, prosperity, respect, freedom, rights, fairness and many other significant meanings that no other word in any language can express better. However, managing, leading, achieving, and sustaining democracy in its true meaning is very difficult, not to say almost impossible. In this research we developed and defined a democratic company culture method and revealed its main components through a new organizational co-evolutionary spiral method and a process for creating a culture that suits different organizations. Companies can create new knowledge, initiate, innovate, understand, perceive and apply the results from the method and manage and lead the company to improve the degree of democratic company culture. Theoretically, the overall procedure adopted in our research is the same as that which has been presented for human and company performance improvement. First, the actuality is viewed through the current democratic behavior. Then the capability and the potentiality in the organization are examined. In this process, the indicative critical issues addressed and answered are: Actuality > what are we managing to do now for our organization’s democratic behavior? Capability > what could we achieve now to develop democratic behavior in our organization? Potentiality > what could we be doing to develop our organization’s democratic behavior? This paper presents our first approach towards identifying and defining the degree of company democracy.

Published: February 2022

The idea of creating sensory gardens, also known as gardens of senses, is developing around the world since the beginning of the 20th century. Such places are organized mainly for the disabled people for the purpose of socializing, therapeutics and education. Spatial zones of sensory gardens refer to different senses like taste, smell, touch, hearing, kinesthetic sense and others. Following towards social expectations, the authors of the paper have taken the task which resulted in developing detailed guidelines for constructing innovative educational and recreational path called the Greenhouse of Senses dedicated to visually impaired as well as to healthy people. Three aims were given at the beginning of the research. The first was bringing new values into education programme for children and young people with visual disorders. The second was to develop a sensory garden independent from the climate conditions. The third task was to extend the available offer aimed at advancing integration processes between disabled and non-disabled people. Chosen research methods, which are based on close cooperation with users, as well as with experts on ergonomics, pedagogy, psychology, sociology, physiology, dendrology and others, are to bring effects in the form of the development of the functional and spatial plan including the arrangement and detailed equipment for this unprecedented educational training ground of a limited volume.The assumed final effect of the authors’ research is constructing a model facility near the school for blind and partially sighted children in Dąbrowa Górnicza (Poland) and supporting the implementation of new teaching methods and reinforcing integration processes within the facility, as well as in wider range of the city and the region.
Comprehensive Inclusive Design for Public Transport System in Shanghai

Published: February 2022

Recently, inclusive design is one of the most significant principles involved with design for urban public facilities, and urban public transport system( PTS), as a public facility, normally need to cover different types of users, which forced them to promote the inclusiveness in its service. This led the mainstream design tendency to concentrate on ergonomics of marginalized users. Despite the traditional inclusive design strategy, this paper outlines the evaluation on the other two aspects, which included systematical design and product experience, to complement the current inclusive design in current PTS of Shanghai. In this case, the purpose of this paper is probe the affecting factors related to the systematical issues and the product experience in the public traffic service. Literature study and online questionary concerned with PTS in Shanghai, are the main approaches in this study, which ultimately indicated the issues from the systematical angle and a more comprehensive model of inclusive design system for PTS in Shanghai.
Recommendations for Tracelink Decisions – An Empirical Investigation of Visualizations
Authors: Brandenburg Elisabeth , Zander Stefanie , Figge Asmus , Beier Grischa
Published: February 2022

Today, engineering processes integrate many subsystems from different domains like Mechanics, Electrics or Software. Therefore the systems that are engineered become more and more complex. As system complexity increases, the number of dependencies between subsystems increases as well. Hence, engineers are obliged to keep track on these dependencies via tracelinks. The present paper investigates four types of decision support (percentages, brief information, a traffic light metaphor and a half-star rating) that help engineers to decide if a tracelink should be set or not. Moreover multiple objective and subjective dependent measures were assessed. Despite the pre-study character of the present work results indicate that the half-star rating system was best in terms of objective performance, at least for experts. Implications of these findings are discussed.
Agile Systems Engineering
Authors: Powell Douglas Bruce , Cakmak Kerim
Published: February 2022

Traditionally systems engineering is a heavily document-based approach. The arrival of the SysML modeling language changed the face of systems engineering from a process of creating and reviewing documents to the construction, analysis, and execution of high fidelity systems models. This evolution of systems engineering has resulted in improved requirements specification, better architectural definition, and better hand off to downstream engineering, including mechanical, electrical and software development. What is needed now is a process that takes advantage of the advances in model-based engineering (MBE) while at the same time reduces the time and effort required for systems engineering. Agile methods have proven successful in the software domain, but how can these incremental, iterative, and agile methods be applied to systems engineering? This is a talk about how agile methods have had a tremendous impact on the development of embedded and real-time software and how to best gain the advantages of agile methods within the systems engineering domain.
Usability of Document Management Systems Considering Users' Level of Experience: A Survey
Authors: Heinicke Antje , Bröhl Christina , Bützler Jennifer , M. Schlick Christopher
Published: February 2022

Through the use of Document Management Systems (DMS) companies can enhance the automation of processes within documents’ registration, classification, processing, archiving and distribution. However, the usability aspect in current selection processes of DMS is inadequately represented. The reason for this neglect is the fact that although functional criteria can be easily formulated for the evaluation and selection of DMS, it is very difficult to specify criteria concerning usability. Objective criteria need to be developed, which can be used a priori for the evaluation and selection of DMS. The criteria have to be developed in a way that they (referring to usability) are applicable to non-specialist users in SMEs. In order to develop these criteria, the existing usability weaknesses of DMS have to be identified as well as the users’ skills, tasks and requirements. In this paper results of a survey are presented.
Layout Structures of Network Diagrams in Project Management Software: An Age-Differentiated Empirical Investigation Concerning Symmetry and Space
Authors: Bützler Jennifer , Brömme Romy , Bröhl Christina , Jochems Nicole , M. Schlick Christopher
Published: February 2022

The use of network diagrams in project management software is a useful tool when planning projects. However, working with these diagrams can quickly become confusing when dealing with complex project plans. This effect is even more pronounced for older persons as they have to deal with age-related changes in perception, cognition and motor control. Nevertheless, project planning is often accomplished by older employees due to their knowledge and experience. There are certain aspects of layout structures that can support perception and decision making when working with complex diagrams. This paper describes an age-differentiated study in which the factors symmetry and spatial distance between activities were investigated. In order to gain practical relevance, the study combined different tasks and different complexities of visualization. In addition to reaction times and errors, eye tracking data was analyzed to acquire additional information. The results of this study reveal that the work with network diagrams can benefit from a proper designed layout structure regarding symmetry and distance. A symmetrical structure and narrow distances led to improvements in performance for all age groups.
