Kinematic body responses and perceived discomfort in a bumpy ride: Effects of sitting posture

The present study investigates perceived comfort and whole-body vibration transmissibility in intensive repetitive pitch exposure representing a bumpy ride. Three sitting strategies (preferred, erect, and slouched) were evaluated for perceived body discomfort and body kinematic responses. Nine male and twelve female participants were seated in a moving-based driving simulator. The slouched posture significantly increased lateral and yaw body motion and induced more discomfort in the seat back area. After three repetitive exposures, participants anticipated the upcoming motion using more-effective postural control strategies to stabilize pelvis, trunk, and head in space.Comment: 4 pages, 2 tables, 1 figur

The Influence of applied pressure on the seated person and the prediction of early discomfort - protocol for a systematic review

Sitting comfortably in a vehicle, office or at home, besides design characteristics, requires excellent physical support of the material to the exposed body segments. An uncomfortable seat can cause well-known pain such as lower back pain, which is nowadays become as "chronical" pain among all the seated workers. This systematic review protocol is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) Statement and presents a methodology to find possible evidence of critical values of the applied pressure which can cause a negative impact on the soft tissues of the seated person. Furthermore, if it is possible to correlate obtained critical values with the time spent in the sitting position. Based on this, the main databases (Scopus, PubMed and Science Direct) will be searched using the same keywords combination for all of them. Afterwards, articles selection process, data extraction, and validation will be approved independently by the reviewers and collected data will be summarized in a spreadsheet table. Outcomes of the selected articles will be examined in the details and will be analyzed in order to extract the main results.</jats:p

COVID-19 AND THE ENVIRONMENT – THE ROLE OF THE PUBLIC HEALTH INSTITUTE

The Croatian National Health Care Act defines the areas of activities of the public health institute, including the activities of the epidemiology of infectious diseases and chronic non-communicable diseases, public health, health promotion, environmental health, microbiology, school and adolescent medicine, mental health and addiction prevention at Zagreb City level. This paper reviews the highly variable activities in the Andrija Štampar Teaching Institute of Public Health with the aim of promoting a comprehensive approach to the COVID-19 pandemic. Human and analytical resources in the Institute, activities and rapid implementation of innovations testify to the high capacities for adaptation to emerging risks. In the Institute, it is possible to carry out a whole range of tests and to monitor the environmental factors with predominant impact on human health and safety of the Zagreb environment. The supply of safe water for human consumption in the Republic of Croatia during the current COVID-19 crisis has been uninterrupted and in accordance with applicable legislation. Also, our laboratories have been developing and introducing a method for wastewater testing for SARS-CoV-2 presence. The sludge from wastewater treatment plants is used in agriculture, and potential risks associated with the COVID-19 outbreak should be assessed prior to each application on the soil. Increased use of disinfectants during the epidemic may present a higher risk to the aquatic environment. Air quality monitoring indicates a positive impact on air quality as result of isolation measures

Influence of External Factors on Business of Companies in Serbia

Business environments can be internal and external. In this paper you will see how external business environments affect business enterprises. They can affect business results positively or negatively. Empirical research was conducted on 60 companies in Serbia. The results show that the external environment is not influencing their businesses favorably. The most negative factors are political. In order to eliminate the negative impact of these factors, it is necessary for the government to take certain measures

PRIMENA HEART METODE ZA PROCENU LJUDSKE POUZDANOSTI – SRPSKO ISKUSTVO

In complex industrial systems, human error has been cited as a cause or a contributing factor in accidents and disasters. The need for improved Human Reliability Assessment (HRA) methodologies that should be applied in Probabilistic Safety Assessments, ever since the early 1990s, has motivated a number of major activities in research and development worldwide. Therefore, the main purpose of this paper is to show the practical application of Human Error Assessment and Reduction Technique (HEART) for HRA in Electric Power Company of Serbia (EPCS). The usefulness of this technique for HRA has been approved in a case study of an accident which occurred during a repair on a 10/0.4 kV steel lattice tower “Maričiće“, Kuršumlija (jurisdiction of EPCS, ED “Jugoistok”, Nis, Serbia). For the purpose of this study, a database on work-related injuries, accidents, and critical interventions that occurred over a 10-year period was created. The research comprised an analysis of 1074 workplaces, with a total of 3997 employees. The case study performed at the EPCS confirmed that the HEART is based on knowledge of human activities and relies on expert opinion to determine the Error Producing Condition (EPCs) that affected the situation. The HEART can be used in different industrial systems, as a risk assessment, accident investigation and design tool. In addition, it is a relatively fast tool for assessment of human error probability that is easily applied and understood. U kompleksnim industrijskim sistemima ljudska greška je često navedena kao uzrok ili glavni faktor koji dovodi do akcidenata i katastrofa. Potreba za poboljšanim metodologijama za procenu ljudske pouzdanosti, koje se primenjuju u probabilističkoj proceni bezbednosti, još od ranih 1990-tih motivisala je brojna istraživanja. Glavni cilj ovag rada je da prikaže praktičnu primenu “Tehnike za procenu i redukciju ljudske greške” u proceni ljudske pouzdanosti u preduzeću “Elektroprivreda Srbije”. Korisnost ovog alata, za ovu namenu, dokazana je u studiji slučaja u kojoj je izvršena analiza akcidenta do koga je došlo prilikom intervencije na čelično-rešetkastoj TS 10/0,4kV „Maričiće“, Kuršumlija, ED „Jugoistok“, Niš. Za potrebe ove studije kreirana je baza podataka o povredama na radu, akcidentima i kritičnim intervencijama u poslednjih 10 godina. Istraživanje je obuhvatilo analizu 1074 radna mesta sa ukupno 3997 zaposlenih. Studija slučaja koja je sprovedena u Elektroprivredi Srbije potvrdila je da se “Tehnika za procenu i redukciju ljudske greške” zasniva na poznavanju aktivnosti operatora i da za procenu “uslova za nastanak greške”, koristi stručno mišljenje eksperata. Tehnika za procenu i redukciju ljudske greške može da se koristi u različitim industrijskim sistemima kao alat za procenu rizika, analizu akcidenata i projektovanje. To je relativno brz, lako razumljiv i jednostavan alat za procenu verovatnoće ljudske greške
