It was proven that continuous exposure to noise affects the blood flow velocity through the aorta and increases the diameter of ascending aorta and this, consequently, leads to an increase in cardiovascular risk. Prevention of changes in the cardiovascular system is considered to be imperative, and the limitation of noise levels and the length of exposure to noise must be established as factors that must be planned during the construction of the work environment.

An analysis of such a workplace was carried out in this paper. The workloads at specific body zones were determined, whether they were within the prescribed limits or exceeded it, and on that basis a redesign of the workspace was made in accordance to the anthropological values of the model.

This problem is generally complex and it is usually associated with artificial intelligence and advanced numerical computations. Standard algorithms such are A*, Dijkstra's algorithm, genetic algorithms or breadth-first search are among the most popular for such problems. In this paper we present a graphical simulation system in 2D that effectively solves a path finding problem based on a well known A* algorithm. A* algorithm is used because of its popularity, flexibility and the fact that can be applied in a wide range of contexts. The programming is done in the C# language under the latest .NET 2.0 framework. The resulting software is tested on number of different configurations and optimal solutions are found quickly and effectively. It is shown however, that if the...

The analysis is based on observation of the end positions of this mechanism. Mathematical expressions have been obtained that describe these conditions and these expressions are generalizable to any geometry of a four-joint mechanism. These results are also described graphically in the form of diagrams. Several numerical examples of combinations of the lengths of the individual members of the mechanism during its motion are also presented.

The high level of excessive biomechanical stress is associated with the established practice of using standard medical wheelchairs to move patients inside the hospital. The process itself depends on the characteristics of the patient, his or her weight, as well as his/her cooperativeness, but primarily depends on the nurse's mobility. Although nurses strive to be in a position that reduces the load on the lumbosacral part of the spine during practice, this is often impracticable due to the patient's inconsistency. Objective: To present the ergonomic analysis of the medical nurse's workplace while lifting the patient into the w...

Spiroergometry provides additional criteria for the assessment of cardiopulmonary efficiency compared to simple ergometry. Maximal oxygen consumption (VO2max) is the most critical variable during spiroergometry. Most submaximal exercise measures provide the heart rate (HR) response to predetermined workloads in equations or nomograms used to predict VO2max. According to previous studies, the heart rate is divided into five fields. In this paper, we are doing a new redistribution of heart rates-to-workloads into seven fields, corresponding to the ergo bar. In other words, an answer is given based on the initial anthropological values of the subjects, when and in which field there will be a mismatch between the lung capacity of the subjects and the power required for that field.

The faculty forum on a real community server, where students and stuff share their knowledge and experiences, is used for this purpose. In order to better understand the structure of the network, we represent it as a graph, where vertices are represented by the members of the forum and the edges act as the links between the forum posts. As in many similar systems, this forum is organized in threads that are divided into sections (subjects), and sections are divided into groups (academic years). It is shown that the resulting network exhibits a scale-free distribution with large clustering coefficients following the small-world properties. As the clusters hold some important information about the nature of the network, we developed a special software agent that explores the background SQL database and automatically acquires the relevant information. Based on this data, detailed informa...

In addition to poor posture habits, "sedentary lifestyles" and insufficient physical activity, school bags is one of the main causes of low back pain and deformity in pupils. The recommendation of the World Health Organization (WHO) is that the weight of the school bag should not exceed 10% of the student's weight. However, in practice these limitations are far from reality with the obvious problems caused by too heavy bags. The aim of the paper is to identify and analyze the backbone load caused by the overweight school backpacks in real school work conditions and eliminate them by creating new solutions that are in line with ergonomic and biomechanical principles, as well as the recommendation given by WHO. Methods: The research included first grade primary school students at the age of seven, including their pare...

Abstract Background: The subject of this research is the creation of an optimal school bench design with the aim of determining the most favorable posture of students while sitting, taking into account the relevant ergonometric and biomechanical characteristics of the human body. For the proposed model of the school bench which allows adjusting the different slopes of its surface, the corresponding computer model of the student and the table was first created, and then biomechanical and RULA analysis was performed in order to determine the maximum load in the lumbar part. Next, for each test subject of given weight, it was necessary to determine the amount of maximum load in lumbar zone L3/L4 for different slope angles and to determine the critical angles at which the maximum permissible load of 3400 N is reached.

Noise pollution occurs when the ear is exposed to the volume of sound that is disturbing, stressful or directly damaging hearing, but also acting on the organism as a whole. Aim: The aim of the article is to examine the vulnerability of workers working on the "press" machine, and to carry out an analysis and examine the press operator workplace, then perform the noise spread measurement in the press operator work area and compare the current measurements with the permissible levels and analyze the time period of worker exposure, as well as presentation of the effects of noise on productivity and workers health. The aim of the article also includes the proposal for decrease of noise pollution. Methods: A noise analysis at the workplace of workers working on a "press" machine was performed, which is exposed to a high impulse noise due to which the quality and quantity of production are reduced. For the purpose of calculating the noise level for one working day at the press operator site 1, 2 and 3, it is necessary to analyze the noise level in time. Operators spend most of their working hours at stations 1 and 3 where the measured noise level is L m1 = 94.7 dB is taken, or at position 3, L m3 = 97.2 dB. The measured noise level at these locations without the operation of the press is L m1 = 80.1 dB, or at station 3 is L m3 = 80.1 dB. Results: It was found that these operators working on the machine in question were exposed to a noise over the limit for more than three years. Their health problems that arise as a result of noise exposure are documented in their health charts. In order to achieve uninterrupted work at the press machine, during the eight hours shift, a noise correction is required to allow the equivalent sound level to fall within one day to the permissible 85 dB. In this regard, we consider the fact that we have known that the press produces a sound level of 110 dB, and that there is a reverberation (reflecting) sound. Given the technical characteristics of the plant, the reduction of the sound intensity of the source itself is not possible, so the suggestions of the technical solution will be based on reduced reflected sounds and to prevent the spread of direct sound to the operator. Conclusion: Workers are exposed to permanent noise during a working day, which produces a number of consequences for the health of the worker, but also the employer and the community. The imperative of the employer is to reduce the number of rejects, increase profitability and to have a positive impact on the health of the individual.

Aim: The aim of this research was a biomechanical-mathematical analysis of 3S in basketball, in order to determine the key parameters for performing a 3S. Results: The research shows a model of shooting a basketball player from the central position of the shot with 6.75 m. The modeling led to the conclusion that the height of the throw, the speed and the angle of the throw of the ball have a positive and direct relationship with the angle at which the ball falls into the basket when it comes to a shot for three points. Conclusion: The height of the throw, the speed and the angle of the ball have a positive and direct relationship with the angle at which the ball hits the basket when it comes to a shot for three points. Anthropometric characteristics of the player, such as the length of the arm, and the height of the player, directly lead to a positive relationship with the throwing angle.

Aim: To present effect of noise on arterial tension and heart rate of workers who work on machine press during period of three-years. Methods: The study had a prospective character and included 30 subjects (n = 30) who were monitored over a three-year period (36 months). The respondents worked at the factory “Cimos” on machine press (Zenica, Bosnia and Herzegovina).Ten machine presses were monitored, and three workers worked on each press. Approximately every worker was affected by a wide range of noise between 65 and 110 dB in the workplace (via isohypse). MATLAB (version 9.4, MathWorks, Natick, Massachusetts, United States of America (USA)) software was used to estimate the possible damage caused by noise in factories that produce noise in their work. Results: During the three-year period, arterial tension in the subjects increased, and at the end of the observed period, they were considered as patients with a diagnosis of arterial hypertension grade I. The tension depends on the strength of the produced noise, and the values also depend on position of the respondent on the machine press. Conclusion: Noise prevention has become a problem of modern medicine. The result of our work allows estimation of arterial hypertension in specified time in case of exposure to a certain strength of noise. Prevention of noise, daytime noise prevention as well as better equipment for work and preventive equipment are imposed as imperative in such or similar conditions, with the need of development of national strategies for this issue in countries where they are not present. Key words: noise, cardiovascular risk, arterial hypertension, heart rate.
