Crane Cabins Development - Are there Innovations Needed?

The use of load lifting/handling equipment makes workplaces dangerous given the high potential for injury, loss of life and material damage. Cranes are extremely important component in many different industrial operations today. Previous researches have highlighted the need of such equipment to be safely operated and easily maintained, while associated human errors should be considerably reduced. Hence, human centered issues have to be analyzed first and according to those conclusions certain innovations are necessary. This survey offers new crane cabin design based on univariate and multivariate approaches applied on operators' anthropometric data in aim to enable their ergonomic convenience. Later, design issues are solved, through static and dynamic calculations using finite method elements in that context. Finally, crane cabin design in the light of Industry 4.0 concept is further analyzed together with inventions that are helpful there. Accordingly, we can conclude that in crane cabins development process proposed innovations are needed and very beneficial

Crane cabins' safety and ergonomics characteristics evaluation based on data collected in Sweden port

This paper presents an evaluation of crane cabins safety and ergonomics characteristics. It is based on previous research data collected for benchmarking analysis for crane cabins operating in one port in Sweden. Six crane cabin types are examined regarding eight characteristic divided in three groups: operator-control devices interaction, safety and anthropometric adjustment according to needs weighting data. Primary analysis of those data was conducted using Pareto analysis. Further analysis are done using developed indexes of characteristics performances while final conclusions were drawn for characteristic of crane cabins using crane index of performance. Taking into account all examined crane cabins only 52.5% of operator-control devices interaction, 75% of safety and 60% of anthropometric adjustment issues are satisfied in current designs

Semantic unification and search of bioinformatics databases

Analyzing biological data from various sources offers a comprehensive perspective of a domain, facilitating the identification of patterns that would otherwise be challenging or impossible to observe when focusing solely on individual biological entities. The process of linking data from different databases can present challenges due to inconsistencies in properties and identifiers assigned to the same entity across databases. Although certain databases include a range of identifiers from multiple sources, the search capabilities are restricted to exact property matching, preventing the execution of complex queries involving multiple metadata attributes. We designed a novel data framework that aims to address these challenges by facilitating the linkage and retrieval of information from diverse interconnected biological data sources. To evaluate the effectiveness of the model, we conducted tests and created a knowledge graph using metadata extracted from five separate public datasets: DisProt, HGNC, Tantigen 2.0, IEDB, and DisGeNET. The resulting graph establishes connections between more than 17 million nodes, comprising 2.5 million distinct biological entity objects, and encompasses over 4 million relationships. Additionally, we designed and implemented a general-purpose procedure for extracting new relationships based on semantic similarity from data transformed into the BioGraph data model.Book of abstract: 4th Belgrade Bioinformatics Conference, June 19-23, 202

Differences in anthropometric measurements between Libyan and Serbian passenger car drivers and crane operators

This paper is a part of ongoing research on passenger car drivers' and crane operators' anthropometric measurements data collected in aim to make comparison, explore ergonomic adaptation and fi nally improve safety. It represents one of the rare explorations containing the Libyan male drivers and crane operators' data, and accordingly it is one of the fi rst researches in anthropometric fi eld on Libyan population. Herein, statistical analysis on Libyan 300 male drivers and 50 crane operators collected data shows that male drivers are taller, and have higher sitting height as well as upper leg length values, while crane operators have slightly wider shoulders and hips. Both Libyan groups have the same arm and foot lengths. Apart of Libyan male car drivers and crane operators, research includes also and Serbian car drivers (921 Serbian male drivers) compared with crane operators (83 crane operators). Obtained data show that Serbian male car drivers have signifi cantly larger standing height and upper leg length values, while foot length is signifi cantly lower for drivers than for crane operators. Passenger vehicle and crane cabins designers can benefi t from this survey

Differences on anthropometric measurements of the hand based on laterality in Serbian context

Anthropometric data are essential for designers of products, while hand anthropometric measurements are of special importance due to the fact that grasp enables different manipulation tasks. Literature review shows that differences on anthropometric characteristics of the hand based on laterality in Serbian context have not been examined till now, so this study tested it on the sample containing 110 subjects - 23 left-handed and 87 right-handed. Hand anthropometric measurements include 30 anthropometric dimensions measured on each examined participant. Dimensions are taken by capturing the imprints of the subjects' outstretched hands. Collected data were subjected to descriptive statistics, t-test, Kolmogorov test and Mann-Withney U* tests. Also, 5th and 95th percentiles are calculated on all dimensions. Results show that there are no statistically significant differences based on laterality in Serbian context. Accordingly, hand tools and many other equipment, which are controlled by means of Serbian operator could be designed in the same manner both for workers whose dominant had is left and right. Also, percentiles values are calculated and should be taken into account in design processes. It is recommended, in future research to enlarge sample, repeat statistical testing and analyze hand grasp possible issues

Analysis of the Frequency of Verbal and Vocal Signs in True and False Statements

The paper presents research aimed at analysing the frequency of verbal and vocal signs in a situation of false and true statements, by introducing a secondary task. The research involved 100 students (47 men and 53 women) of the master's studies of criminal investigation at the University of Criminal Investigation and Police Studies, aged 23-44. Students had the task, based on the observation of twenty selected videos (10 true statements and 10 false statements), to mark the frequency of each individual verbal and vocal sign, on a previously generated and prepared list. The results show that there is a statistically significant difference in terms of the frequency of all verbal and vocal signs in a false or true statement: response latency, speech hesitation, speech errors, speech rate, number of spoken words in the utterance, and length of utterance. Response latency, speech hesitation, and speech errors have higher median values in false utterances than in true ones, while speech rate, number of words spoken, and length of utterance show higher median values in true than false utterances

Organizational culture and quality improvement: Differences across continents

Prethodna istraživanja pokazuju da organizacioni faktori utiču na programe unapređenja kvaliteta, na način da su performanse preduzeća bolje kada postoji usaglašenost između navedenih faktora. Stoga je cilj ovog rada analiza međuzavisnosti organizacione kulture i programa unapređenja kvaliteta kroz testiranje razlika između dimenzija organizacione kulture i tehnika i procedura unapređenja kvaliteta u kompanijama koje posluju u 32 zemlje sveta. Nakon detaljne analize prethodnih istraživanja, prikupljeni su potrebni podaci u 200 preduzeća koja su deo lanca snabdevanja multinacionalne kompanije. Zatim je sprovedena statistička analiza poređenja preduzeća zavisno od lokacije, odnosno pripadnosti određenom kontinentu. Rezultati pokazuju da postoje statistički značajne razlike dimenzija organizacione kulture i primenjenih postupaka upravljanja kvalitetom zavisno od geografske lokacije preduzeća. Tako, rezultati ovog rada potvrđuju opravdanost primene kontekstualnog pristupa promovisanog u standardu ISO 9001:2015 i ukazuju na činjenicu da multinacionalne kompanije treba da odrede stepen lokalizacije organizacione kulture i prakse menadžmenta kvalitetom radi usagalašavanja sa kontekstom zemlje u kojoj posluju.Previous research shows that organizational factors influence quality improvement programs, and when there is a fit, it is leading to better business performances. Accordingly, the purpose of this paper is an analysis of interdependence between organizational culture and quality improvement via testing the differences between dimensions and types of organizational cultures and applied procedures for quality improvement techniques on companies from 32 countries worldwide. Following detailed exploration of the available literature, data collection is conducted on 200 production enterprises in multinational supply chain. Upon this, further statistical examination is conducted by comparison of the companies in dependence of its locations - continents. Results show that there are significant differences on dimensions of organizational culture and applied quality improvement procedures depending of geographical location of companies. Accordingly, results of this paper prove that contextual approach promoted in ISO 9001:2015 has to be applied and organizations that operate in different countries and continents must decide how much to localize their organizational culture and related management practices to fit within the host country context
