Abstract:
Early settlers in southern Ontario aspired to become prosperous land-owning farmers; they began by cutting trees. Within a few decades, wind and water, unimpeded by forest cover, devastated soil and crops. Farmers were encouraged by groups such as the Ontario Fruit Growers’ Association to reforest some of their land. Farm forestry, as part of scientific agriculture, had a strong beginning in the early 1900s with the Ontario Agricultural and Experimental Union, but that movement was poorly supported until the 1930s, when the relationship between deforestation and water supplies reached a crisis. The Ontario Conservation and Reforestation Association (OCRA) and the Ontario Crop Improvement Association (OCIA) were created in agricultural southern Ontario in 1937-8 after a disastrously hot dry summer. Each organization interpreted the conservation of natural resources in profoundly different ways: the OCRA as a movement to create forest resources on public property, and the OCIA as management of privately-owned farmlands to improve crop production.

Abstract:
Abstract. Accurate knowledge of cloud properties is essential to the measurement of atmospheric composition from space. In this work we assess the quality of the cloud data from three Copernicus Sentinel-5 Precursor (S5P) TROPOMI cloud products: (i) S5P OCRA/ROCINN_CAL (Optical Cloud Recognition Algorithm/Retrieval of Cloud Information using Neural Networks;Clouds-As-Layers), (ii) S5P OCRA/ROCINN_CRB (Clouds-as-Reflecting Boundaries), and (iii) S5P FRESCO-S (Fast Retrieval Scheme for Clouds from Oxygen absorption bands – Sentinel). Target properties of this work are cloud-top height and cloud optical thickness (OCRA/ROCINN_CAL), cloud height (OCRA/ROCINN_CRB and FRESCO-S), and radiometric cloud fraction (all three algorithms). The analysis combines (i) the examination of cloud maps for artificial geographical patterns, (ii) the comparison to other satellite cloud data (MODIS, NPP-VIIRS, and OMI O2–O2), and (iii) ground-based validation with respect to correlative observations (30 April 2018 to 27 February 2020) from the Cloudnet network of ceilometers, lidars, and radars. Zonal mean latitudinal variation of S5P cloud properties is similar to that of other satellite data. S5P OCRA/ROCINN_CAL agrees well with NPP VIIRS cloud-top height and cloud optical thickness and with Cloudnet cloud-top height, especially for the low (mostly liquid) clouds. For the high clouds, S5P OCRA/ROCINN_CAL cloud-top height is below the cloud-top height of VIIRS and of Cloudnet, while its cloud optical thickness is higher than that of VIIRS. S5P OCRA/ROCINN_CRB and S5P FRESCO cloud height are well below the Cloudnet cloud mean height for the low clouds but match on average better with the Cloudnet cloud mean height for the higher clouds. As opposed to S5P OCRA/ROCINN_CRB and S5P FRESCO, S5P OCRA/ROCINN_CAL is well able to match the lowest CTH mode of the Cloudnet observations. Peculiar geographical patterns are identified in the cloud products and will be mitigated in future releases of the cloud data products.

Abstract:
Abstract The Outreach Cosmic Ray Activities (OCRA) project was created in 2018 within the Italian Istituto Nazionale di Fisica Nucleare (INFN) to offer a platform for all outreach activities focusing on cosmic rays within the institute. OCRA now counts 22 of the institute’s divisions all over Italy as members. The project offers activities both for students and teachers. The one activity common to all local groups is the participation in the yearly International Cosmic Day, organized by DESY, inviting high school students to carry out hands-on measurements of the cosmic ray flux and learn about the related physics background. Two students from each division are then selected to participate in the annual OCRA science camp, a three-day full immersion into the life of a physicist. For both teachers and students, the OCRA website https://web.infn.it/OCRA/, offers a series of online laboratories designed both to be used by students individually but also to be offered in the classroom by teachers. A section dedicated to teachers provides ample material to help bring these laboratories to the classroom. The online materials were presented in a course for teachers in spring 2021. In addition to the national efforts, there are also local initiatives of the OCRA member groups: workshops and secondments, science competitions and the development of new detectors for outreach activities offer a multitude of possibilities for students to engage with our researchers and to explore the world of cosmic rays. This article provides an overview on all activities offered by OCRA with a particular focus on the 2022 science camp.

Abstract:
Los desórdenes musculo esqueléticos (DME) son la nueva epidemia de enfermedades crónicas, son multifactoriales y afectan los diferentes sectores productivos. Aunque se encuentran múltiples instrumentos para la evaluación de la carga estática y dinámica, el OCRA (Occupational Repetitive Action) parece ser una opción atractiva. Objetivo. Realizar una búsqueda de literatura sobre el uso del método OCRA y DME en trabajadores de diversos sectores productivos (2007- 2018). Materiales y métodos. Una revisión de literatura (siguiendo la declaración PRISMA) de estudios que evaluaran el nivel de riesgo biomecánico (OCRA) y DME en las bases de datos Scielo, Science Direct, Scopus, ProQuest, Gale, PubMed, Lilacs y Ebsco fue realizada, 7 estudios cumplieron con los criterios de selección; la mayoría son cuantitativos (corte transversal). Resultados. El 79% de las condiciones relacionadas con la tarea requieren exigencia física e implican movimientos repetitivos (jardinería y floricultores); la aparición de DME en espalda alta-baja, extremidades superiores e inferiores, los cuales se generan por la frecuencia de las actividades realizadas (producción de calzado); además, “riesgos muy alto” de desarrollar DME (industria del salmón) y un índice medio (OCRA) por movimientos repetitivos que requiere cuidado especial (línea de Ensamblaje en U) fueron encontrados. Conclusiones. La revisión arrojo el uso limitado del método OCRA para la detección de DME en trabajadores de diferentes sectores; y este método puede ser usado para la detección del riesgo biomecánico.

Abstract:
In this paper we consider scheduling problem under ergonomic risk factors. We recruit OCRA index to control musculoskeletal disorder along schedule. Modern manufacturing systems competition power depends on cost, time and flexibility level. Despite of high level automation in manufacturing system, flexibility depends on human workforce. From this perspective, for gaining high rate production, workforces have to endure high frequency manual job. This case causes musculoskeletal disorder. Musculoskeletal disorder which had to be control is one of the most important ergonomic risks in work environment. We used OCRA index mean value for ergonomic risk assessment. We also named this new type of scheduling as Ergo-Scheduling. Keywords: Ergonomic risk assessment, scheduling, single machine scheduling, deterioration, OCRA Index;

Abstract:
Lietuvoje nėra didelės ergonominių rizikos veiksnių vertinimo metodų taikymo praktikos, ji tik kuriama. Šios srities specialistų ir tiriamųjų darbų nėra daug, todėl tai ypač aktualu. Tyrimas atliktas naudojant aprašomąjį ir anketinės apklausos metodą, o rezultatai apdoroti statistiniais metodais. Nustatyta, kad dažniausiai taikyti metodai yra: REBA ir RULA, anketiniai tyrimai, LST EN 1005-2, LST EN 1005-4, LST EN 1005-5, fizinio darbo intensyvumo tyrimas taikant Brouha ir Rohmerto kriterijus, MAC, NIOSH-KRS, OCRA (OCRA rodiklis, OCRA patikros lapas). Galima daryti išvadą, kad REBA ir RULA metodai yra dažniausiai naudojami, nes lengvai pritaikomi, gaunamas konkretus balas ir pateikiamos gautų balų vertės. Taikant kitus metodus, sugaištama daugiau laiko, reikia atlikti daugiau matavimų, tyrėjui paliekama didesnė laisvė interpretuoti.

Abstract:
OCRA Tabletop MRI è un setup di risonanza magnetica da tavolo usato a scopo didattico e di ricerca. Il sistema è composto da un magnete permanente da 0.28 T, 4 bobine di gradiente e una bobina a RF usata sia per trasmettere che per ricevere i segnali. I segnali sono elaborati da una scheda di acquisizione che comunica in rete i risultati delle scansioni. Il setup è abbastanza economico e versatile in quanto permette di personalizzare le sequenze di acquisizione e di modificarle in tempo reale. In questo contesto si è inserito il lavoro descritto in questo elaborato: una interfaccia grafica (GUI) che permettesse di visualizzare il volume acquisito nelle tre viste sagittale, coronale e assiale e di valutarne la qualità. Dalla vista assiale la GUI consente quindi di selezionare delle ROIs (Regions of Interest), regioni di un determinato tipo, forma e dimensione, importanti per valutare la qualità dell’immagine tramite la stima del rapporto segnale rumore (SNR). Gli elementi acquisiti sono phantom alti 30mm con un foro a forma di stella. Da 3 volumi scansionati con una sequenza "spin echo" sono stati eseguiti 2 protocolli di acquisizione per individuare gruppi di ROIs su 2 slice differenti. Queste slice sono state scelte per delle caratteristiche differenti: una rappresenta la zona del volume con maggior segnale, l'altra invece individua una zona con maggiore omogeneità nelle aree che rappresenta. Dai dati risulta che il protocollo non standard è troppo volume-dipendente, quindi poco affidabile per misure su differenti volumi. E' stato fatto anche un breve studio sulla omogeneità delle regioni.

This thesis describes the development of a low-cost, open source, FPGA-based con- sole (hardware controller) for an educational MRI scanner. The console is known as OCRA: Open-source Console for Real-time Acquisition. Conventional MRI con- soles may be high cost, closed-source, and inflexible, in that it is not possible to change acquisition parameters once the scan is started. In contrast, OCRA is under $500, open-source, and capable of real-time updates to the acquisition. In particular, the console can update the sequence of excitations played out by the MRI console, known as the pulse sequence, in real time, a feature unique to this console. For hard- ware, OCRA uses the Red Pitaya, a commercially available Zync SoC board with a dual-core ARM CPU and Xilinx FPGA. The functionality of the console has been demonstrated on the MGH/MIT Tabletop scanners [2] developed in 2014 and used in MIT courses to teach students about signal processing. The major contributions of this thesis are the software programs for controlling and programming the console. They are: a Python-based Graphical User Interface (GUI) or client for controlling the acquisition and manipulating acquired data, a C-based server program for setting the memory of the sequence, and a low-level programming language for developing custom pulse sequences. The software is demonstrated in a basic example of real-time motion correction. In future work, OCRA can be extended to other MRI systems, particularly low-cost and custom built systems. Additionally, the console could be made more user-friendly through a higher-level programming language for developing pulse sequences, which would be built on top of the low-level language developed in this work. Finally, the real-time updating capabilities can be developed further, to correct artifacts (e.g. temperature-based drift) and even to develop a completely automated, data-driven acquisition that builds itself based on the acquired data.

Abstract:
O setor industrial é responsável por uma oferta considerável de postos de trabalho que exigem a realização de movimentos repetitivos, principalmente nos membros superiores, resultando em um número cada vez maior de Lesões por Esforços Repetitivos (LER) ou Distúrbios Osteomusculares Relacionados ao Trabalho (DORT). A prevenção de LER/DORT, pode ser promovida pela aplicação de medidas de gestão e diagnóstico de situações de risco em condições reais de trabalho, com a utilização de ferramentas ergonômicas que avaliem integralmente os principais fatores de risco para a ocorrência de doenças musculoesqueléticas relacionadas ao trabalho. A presente pesquisa utilizou como ferramenta ergonômica, o Método OCRA, em uma indústria no setor metal-mecânico e teve como objetivo, o design de um posto de trabalho e dos seus respectivos procedimentos. A utilização do Check List OCRA possibilitou o mapeamento dos postos de trabalho no Setor Pintura e a caracterização do posto de trabalho com maior constrangimento musculoesquelético por movimentos repetitivos. O Índice OCRA permitiu a identificação e quantificação dos fatores de risco, a previsão de ocorrências de LER/DORT antes e após o reprojeto dos procedimentos e dos postos de trabalho Pintor I. A produtividade dos trabalhadores Pintor I foi mensurada, e observou-se que as melhorias ergonômicas proporcionadas pelo Método OCRA interferiram na produtividade dos trabalhadores. A utilização do Método OCRA e suas orientações para intervenções ergonômicas para o reprojeto de procedimentos e postos de trabalho, possibilitou uma diminuição do Índice OCRA de 15,36 para 2,03, o que correspondeu a um decréscimo de quatro vezes na probabilidade dos trabalhadores apresentarem doenças ocupacionais originadas por movimentos repetitivos. O reprojeto do posto de trabalho interferiu positivamente na produtividade dos trabalhadores, pois a diminuição das ações técnicas e as melhorias das condições posturais resultaram no decréscimo do consumo de tinta utilizado para a pintura das peças metálicas Perfil C; mensalmente, o reprojeto ergonômico, além de possibilitar melhores condições de trabalho, permitiu através dos ganhos de produtividade, economia mensal em mais de 145 kg de tinta para o posto de trabalho Pintor I, sem afetar a qualidade do procedimento. A aplicação do Método OCRA, método reconhecido e recomendado pelas normas internacionais ISO e EN, possibilitou a interface de um método ergonômico, no reprojeto de procedimentos e postos de trabalho, visando melhorias ergonômicas e ganhos de produtividade no posto de trabalho estudado.
The industrial sector is responsible for a high number of working stations which require a lot of repetitive actions, mainly of the upper limbs, resulting in an increasing number of Work Related Musculo Skeletal Disorders (WMSD). The prevention of WMSD, can be promoted by the application of management measures and diagnostic of risk situations in real working conditions, through the use of ergonomic tools to fully evaluate the main risk factors for the occurrence of WMSD. This study employed the OCRA Method as an ergonomic tool in a Metal-Mechanics sector industry and aimed to promote ergonomic improvements and verify the influence of productivity levels in a redesigned working station. The OCRA Check List enabled to map the Paint Sector Jobs and characterize the working station with the highest repetitive action musculoskeletal embarassment. The OCRA Index allowed to identify and quantify risk factors, and predict WMSD occurrences before and after the redesign of Painter I procedures and working stations. Painter I worker productivity was measured and it was observed that the ergonomic improvements provided by OCRA Method influenced the worker productivity. The use of OCRA Method and its guidelines for ergonomic interventions to the redesign of procedures and working stations, resulted in a reduction from to 15.36 to 2.03 in the OCRA Index, which corresponded to four times decrease in the probability of workers presenting occupational disease caused by repetitive actions. The working station redesign positively interfered in the work productivity since the reduction of technical actions and improvement of posture conditions resulted in decrease in consumption of paint used on the Profile C metallic parts; monthly, ergonomic redesign, besides creating better working conditions, enable through productivity gains, savings in more than 145 paint per month for the Painter I working station, without affecting the quality of the procedure. The OCRA Method application, a method recognized and recommended by the international standards ISO and EN, provided the interface of the ergonomic method to the redesign of procedures and working stations, aiming at ergonomic improvements and productivity gains in the workplace under study.

Abstract:
Il presente elaborato si propone di effettuare la valutazione ergonomica delle postazioni di lavoro presenti all'interno del reparto di montaggio dell'azienda Comer Industries Spa. L'obiettivo è quello di realizzare una mappatura del rischio aziendale da movimentazione manuale dei carichi attraverso analisi condotte con metodo NIOSH ed OCRA. Dopo una breve introduzione sulla normativa vigente in termini di salute e sicurezza sul lavoro, verranno approfonditi nel dettaglio i due suddetti metodi di analisi. Verrà in seguito presentata l'evoluzione cronologica della mappatura del rischio aziendale, evidenziando i criteri adottati per la determinazione del rischio. Si vedrà come l'introduzione di azioni migliorative di diversa natura, sia organizzative/gestionali che tecniche, abbia comportato una generale diminuzione del rischio aziendale. Verranno in seguito eseguite nuove analisi ergonomiche per diverse linee del reparto, sempre con metodo NIOSH ed OCRA Index. Si procederà quindi all'estensione della mappatura del rischio alle linee analizzate, ed all'aggiornamento della stessa all'anno 2017. Infine verrà presentato un confronto finale con la mappatura del rischio aggiornata, al fine di evidenziare come i diversi miglioramenti tecnici, abbinati al più preciso metodo di valutazione utilizzato, OCRA Index, abbiano comportato una netta diminuzione del rischio aziendale.

The objective of this study is to analyze the influence of risk factors on exposure to WMSD workers in repetitive activities in the footwear sector. Therefore, we analyzed the data for 71 workplaces in the productive area of a shoe company which are characterized by having a defined task cycle, and had the index of exposure to WMSD upper limbs calculated through the OCRA method. Data analysis was accomplished using the exploratory data analysis of WMSD and construction of a Generalized Linear Model (GLM). This model identified the factors that influence the rate of exposure the most and made it possible to quantify the possible chance of raising this index when risk factors are present in the workplaces. The factor indicated as the most influential one was the "sudden movements" factor, the presence of this factor increases the chance of raising the level of exposure in 2.12 times more than when this factor is not present.

Abstract:
In questa tesi vengono presentati i risultati di un approccio innovativo allo studio dei fattori di rischio per i lavoratori che compiono movimenti ripetitivi e prolungati nel tempo. Per raccogliere i dati necessari e per misurare i fattori di rischio definiti dal metodo OCRA (Occupational Repetitive Action) si sono tradizionalmente usate misurazioni visive dirette o filmati che venivano successivamente usati per estrarre i dati. L’approccio adottato in questo lavoro è basato sull’utilizzo di sensori di movimento applicati sul corpo del soggetto. I sensori trasmettono dati grezzi provenienti da un giroscopio e un accelerometro, che vengono raccolti ed elaborati dal software sviluppato per questa tesi. I vantaggi sono l’immediatezza delle misure e la loro completa oggettività. Come vedremo, alcuni problemi rimangono per la taratura dei sensori e la deriva temporale di alcuni dati, ma superati questi, il metodo analizzato potrebbe essere generalizzato e usato su ampia scala.

Abstract:
Le patologie muscoloscheletriche dovute al lavoro manuale costituiscono un serio problema nel settore metalmeccanico e lavorativo in generale. Per questo motivo, è di grande interesse lo studio delle condizioni a cui sono sottoposti i lavoratori, così come la conoscenza di indici caratteristici per poter ben quantificare il rischio. Il seguente elaborato ha lo scopo di indagare tali condizioni tramite l’ausilio delle più moderne tecnologie di modellazione e acquisizione dati, al fine di incrementare la salvaguardia della salute del lavoratore. Lo scopo dell’analisi è triplice: da un lato si vuole trovare un metodo obbiettivo per quantificare i valori degli indici di rischio da normativa, attualmente valutati con considerazioni soggettive basate sull’esperienza del valutatore; l’uso di questi modelli può inoltre consentire l’ottenimento di informazioni aggiuntive per la quantificazione del rischio; infine, si vogliono ricercare utili correlazioni tra indici da normativa e valori biomeccanici. Tramite tecnologie di analisi del movimento si sono acquisti dati relativi a compiti normalmente svolti da operatori metalmeccanici. Con l’utilizzo del software di modellazione AnyBody sono stati definiti dei modelli biomeccanici che, riproducendo fedelmente l’apparato muscoloscheletrico dell’operatore, hanno permesso un’indagine approfondita e non invasiva utile ai fini della conoscenza dei valori biomeccanici di spalle e schiena. Gli stessi movimenti sono stati analizzati come previsto dall’indice di rischio OCRA proposto in normativa, sia mediante tecniche tradizionali sia mediante le simulazioni. L’analisi dei risultati ha mostrato l’effettiva correlazione tra indici da normativa e valori biomeccanici per un’operazione semplice e comune come quella di foratura. È stato anche mostrato come un metodo di analisi come quello proposto sia non solo poco invasivo, ma anche estremamente funzionale per lo studio dei fattori di rischio per la salute del lavoratore.

Abstract:
The aim of the research is to highlight the factors of risk of the upper limbs biomechanical overload in some agricultural operations and to show how strength and frequency factors are particularly involved. Nowadays, the UL-WMSDs (Upper Limbs - Work Related MusculoSkeletal Disorders) constitute a major health problem for agricultural workers. The latest European and Italian statistics on work-related health problems confirm this and these pathologies are the most common sort of problem experienced. To achieve the objectives of the research, tests have been carried out to aimed at deepening the exposure to biomechanical overload due to repetitive movements of upper limbs as can been seen in certain sectors of Mediterranean agriculture. The risk assessment was performed by means of a method OCRA (Occupational Repetitive Actions), which is a method recognized by the international literature and recommended by ISO 11228-3 and EN 1005-5. The first results confirmed the effect of the "frequency" parameter in the calculation of the biomechanical risk index and generated important question about the use of the Borg Scale, which is to evaluate amount of exertion workers experience in the course of their work, in this matters. These results led to further investigation of the two key markers of risk (force and frequency) during the manual pruning of vineyards with the intention of better understanding how the OCRA method, which was originally designed for highly structured work environments that are very different from the agricultural sector, can be better used in that sector. With regard to the force factor, we conducted laboratory experiments making the effort to replace the Borg scale, using values obtained from the specially made sensorized shear, which was used to cut branches. The five sensors on the shear were capable of detecting the strength and duration of the force applied during the cuts. The results confirm that during the operation the hand forces are function of diameters and cultivated varieties, and certain areas of the hand can be particularly stressed and that methodology and instrumentation used in the experiments was able to show this phenomenon and also the difficulties the workers have in making objective judgments about the strength necessary. Regarding the frequency of cuts, the research has proved that wave pattern of the work productivity curves under consideration is similar to that of the OCRA index and they were calculated on an hourly basis. This trend cannot be ignored when performing investigations in the agricultural sector. In conclusion, the results of the tests carried out have shows that there is a necessity to undertake a proper study of work organization in agriculture. This future investigation should be able to identify and show the trend of frequency curve or there is the possibility of serious miscalculation in the estimation of risks from biomechanical overload., The studies undertaken suggest the basis for an evaluation agricultural workplaces that is not limited to economic concerns but also take into consideration wellbeing, health and worker-safety.

Abstract:
la tesi descrive in che modo si sia potuto collegare il sistema aziendale con le linee guida ISO OHSAS e in che modo queste abbiano aiutato il sistema aziendale dal punto di vista della sicurezza sul lavoro. In secondo luogo si sono analizzate le tipologie di movimentazioni manuali dei carichi prevalentemente compiute dagli operatori sul campo, valutando le posture congrue e non. A questo proposito si sono calcolati tramiti indici caratteristici (NIOSH e OCRA index) i rischi tramite i quali gli operatori sono perennemente sottoposti durante il loro lavoro quotidiano. Dopo questa analisi e valutazione si è passati a una valutazione, tramite le linee guida fornite dall'ente INAIL, del rischio stress sul posti di lavoro; a questo proposito si sono fatti compilare a tutti gli operatori dei questionari inerenti a questa condizione di rischio e infine tramite una valutazione si è potuto constatare che questa condizione all'interno della Bergonzoni Bruno srl non è presente in maniera rilevante. In ultima analisi si è aggiornato il Documento di Valutazione Rischi, il quale rappresenta una guida facilmente consultabile da tutti, nella quale sono riassunti tutti i rischi e le metodologie per evitarli o per ridurli nel caso peggiore.

Abstract:
The OCRA method is the reference method chosen in ISO (ISO 11228-3) and CEN (EN 1005-5) standards regarding risk assessment and management of upper limbs repetitive movements and exertions. The method consists of two specific tools (OCRA index and OCRA checklist). In this paper special attention will be devoted to the procedures for the analysis of multiple repetitive tasks.When computing the OCRA index (checklist score) considering the presence of more than one repetitive task, a “traditional” procedure has been previously proposed. This approach, whose results could be defined as “time weighted average”, seems to be appropriate when considering rotations among tasks that are performed almost once every hour. On the contrary, when rotation among repetitive tasks is less frequent the “time weighted average” approach could result into an underestimation of the exposure level. For those scenarios an alternative approach is based on a concept that the most stressful task is the minimum starting point. A peculiar procedure allows to exactly estimate the resulting index within this range of minimum to maximum values. It is possible to apply this approach also for job rotation with weekly or monthly or annual cycle typical of agriculture, supermarket, cleaning sectors. This paper shows criteria and results in different working situation: plant nursery, viticulture (annual cycle).

Abstract:
A large number of studies show that awkward postures and repetitive hand and wrist movements contribute to the development of work-related musculoskeletal disorders (WMSDs). To effectively prevent these problems, there is a need for precise and quantitative knowledge about the relation between exposure and effect. In most epidemiological studies of disorders of the upper limbs, information about exposure is too limited or imprecise. Moreover, the exposure often involves several dimensions, and therefore it is necessary to use reliable methods to obtain trustworthy risk estimates. Therefore, the aim of this study was to evaluate the risks in relation to repetitive movements of the upper limbs of workers, as well as analyze the effects of a reduced work pace on the risk levels in a fish processing industry. The study was conducted in a Brazilian fish processing industry with 1,900 workers, who were divided into two work shifts. The OCRA checklist was used to assess 10% of the total workforce during work tasks. The 13 main work tasks (homogeneous groups) of the productive sector were analyzed. The occupational repetitive actions performed by workers were 81.5 ± 19.2 per minute, representing 10 points on the OCRA scale (0 to 10 point scale). The average score of the OCRA checklist was 18.4 ± 2.9 (moderate risk). Considering the five risk categories proposed by the OCRA method, 12 tasks were deemed moderate risk (92%) and 1 low risk level (8%). Due to the predominance of the highly repetitive movements of the upper limbs in fish processing work, and previous studies suggesting a reduced work pace to prevent UL-WMSDs, simulations of a pace with very low risk levels were carried out utilizing the OCRA checklist. By conducting these simulated interventions, it was possible to reduce the risk of UL-WMSDs to very low levels in all tasks by only decreasing the work pace (-42.8 ± 17.7%). These results suggest that most of the tasks carried out by workers were classified as moderate risk, predisposing workers to a greater probability of developing UL-WMSDs (10.8 to 21.5%) than the population that was not exposed. Simulations of a reduced work pace showed the effectiveness of this organizational measure in lowering the risk of UL-WMSDs.

Abstract This paper introduces a motion analysis system based on a network of common RGB cameras, which provides the measurement of various angles considered for postural assessment, in order to facilitate the evaluation of the ergonomic indices commonly used for the determination of risk of musculoskeletal disorders of operators in manufacturing workplaces. To enable the tracking of operator postures during the performed tasks, the system exploits the multi person keypoints detection library “OpenPose”. The proposed system has been validated with a real industrial case study regarding a washing machine assembly line. Results suggest how the proposed system supports ergonomists in risk assessment of musculoskeletal disorders through the OCRA index.

Abstract:
The US Army Corps of Engineers operates, maintains, and manages more than $232 billion worth of the Nation’s water resource infrastructure and relies on the Operational Condition Assessment (OCA) process to determine the condition of the assets and their components. The sheer number of components, all of equal OCA scheduling priority, creates challenges in ensuring that assessments are conducted in a timely manner and that data generated are of sufficient quality to inform resource allocation decisions. This research applied methods from systems design to determine the OCA system “as-is” state and create a stakeholder-informed vision of a “to-be” state that addresses current system challenges. To meet its objective of providing current assessments of asset condition, the OCA system must provide four high-level functions: provide access to asset data, conduct assessments, determine asset risk, and prioritize and schedule assessments. The development of capabilities to provide these functions will facilitate the achievement of the OCA system to-be vision: a consistent view of asset condition and risk across the enterprise.
