Noise pollution of the urban environment in recent years has become a serious environmental and social problem, a threat to the health and well-being of the population. Although noise for the population is not such a priority, as, for example, chemical pollution of air and water, but it has always been the subject of public interest. There are varieties of noise generation sources of which the traffic noise could be a major source. Among the many factors affecting the health of the population, urban noise is the most common and aggressive. The article deals with the problem of the negative impact of noise on human health and on the structure of the general morbidity of the population. The authors addressed the problem of noise pollution in the city of Kaluga. Presents the dynamics of changes in the number of cars and noise pollution over the past ten years. It is shown that today cars are the dominant sources of urban noise environment. The interpretation of the results of full-scale acoustic measurements carried out on the main urban highways is given. The regularities of changes in noise levels in different seasons of the year are revealed. It is concluded that the permissible values of acoustic effects in the city of Kaluga are exceeded. The results of the integrated assessment of child morbidity associated with an increase in the number of vehicles in the city and an increase in acoustic load are presented.

The modern urban environment, with the development of industry, the growth of the vehicle's number on the roads, and the increase in the density of buildings, is increasingly capable of negatively affect the health and well-being of the city's population. Among the factors influencing the environment is noise pollution, namely man-made noise - unwanted and harmful sounds created as a result of human activities. Today, noise is one of the most common factors of pollution among all others. The most common source of noise pollution is transport, including cars and trucks, buses, railways, airplanes, etc. The negative phenomenon of traffic noise is that almost everyone is greatly affected. This can often be accompanied by other harmful factors, such as vibration. According to scientific researches, noise can cause irritation under constant acoustic exposure. As a result, there are sleep disorders, decreased mental capacity, and the development of stress, and stress development in humans. Traffic noise is created from the operation of engines, the friction of wheels with the road surface, brakes, and aerodynamic features of vehicles, etc. In general, the level of traffic noise depends on such basic indicators as the intensity, speed, and composition of the traffic flow. Therefore, an important task is the study of traffic noise, its measurement, the establishment of appropriate dependencies, and further evaluation of the results. Knowing the level of noise generated by vehicles, further measures to reduce it are possible, such as redistribution of traffic flows on the road network, speed limits, improving the quality of the road surface, the use of basic means of reducing noise pollution, the use of noise protection devices, etc. Based on this, the negative impact of this phenomenon on the human body and the environment, in general, can be reduced.

Urban noise can interfere with avian communication through masking, but birds can reduce this interference by altering their vocalizations. Although several experimental studies indicate that birds can rapidly change their vocalizations in response to sudden increases in ambient noise, none have investigated whether this is a learned response that depends on previous exposure. Black-capped chickadees ( Poecile atricapillus ) change the frequency of their songs in response to both fluctuating traffic noise and experimental noise. We investigated whether these responses to fluctuating noise depend on familiarity with noise. We confirmed that males in noisy areas sang higher-frequency songs than those in quiet areas, but found that only males in already-noisy territories shifted songs upwards in immediate response to experimental noise. Unexpectedly, males in more quiet territories shifted songs downwards in response to experimental noise. These results suggest that chickadees may require prior experience with fluctuating noise to adjust vocalizations in such a way as to minimize masking. Thus, learning to cope may be an important part of adjusting to acoustic life in the city.

Liberalization of the Indian organizational environment through modification in the industrial, trade and financial policies by the government has brought in change and competition of a magnitude that was previously unknown to Indian business. In the present scenario, where multinationals and other global players are competing in the domestic market with the monopoly players, the management of organizations is expected to be more productive and efficient for survival in India. More than a decade ago, the western countries faced similar conditions. A flow of changing organizational structures and changing expectations has forced various departments of the organization to alter their perspectives on their role and function overnight. In this context, it would be important to identify the factors in the organizational environment that have the most positive as well as negative impact on their performance in the organization in order to facilitate the positive and impede negative factors at job setting. Hence, the present research was undertaken to find out, how occupational stress and human resource practices can contribute to psychological well-being among employees of I.T companies.The main factors affecting the job satisfaction of the I.T. employees are based on Age, Gender, Educational qualification, Marital status, Experience, Salary, Nature of employment. The data collected will be analyzed with the usage of the statistical tools like one way ANOVA, factor analysis and independent t- test. The major findings are reported at the completion of the project work and on the basis of the study, suitable suggestions will be given to the company.

The One Health concept recognizes that the health of humans is connected to the health of animals and the environment. The major aim of the One Health is to improve health and well-being through the prevention of risks and the mitigation of effects of crises that originate at the interface between humans, animals and their various environments.Regardless of which of the many definitions of One Health is used, the common theme is collaboration across sectors. Collaborating across sectors that have a direct or indirect impact on health involves thinking and working across silos and optimizing resources and efforts while respecting the autonomy of the various sectors. To improve the effectiveness of the One Health approach, there is a need to establish a better sectoral balance among existing groups and networks, especially between veterinarians and physicians, and to increase the participation of environmental and wildlife health practitioners, as well as social scientists and development actors.As this kind of collaboration newly introduced in Mongolia, there are numerous complications and difficulties may arise, that eventually could lead to the results, with higher negative impact to the public and personal health. From the technical perspective, it is undoubtfully important to evaluate the system and reveal the gap and weakness of each stakeholder in this important network and try to introduce common standard operational procedures for the handling and maintaining infective agents to avoid the unpleasant spill over the pathogen into the environment.Mongolian Journal of Agricultural Sciences Vol.13(2) 2014: 146-152

Tram system is a backbone of public transportation in the City of Zagreb. In the last decade, its fleet has been renewed by 142 new low-floor trams. Shortly after their introduction, it was observed that they have a negative impact on the exploitation behavior of tram infrastructure, primarily on the durability of rail fastening systems. Because of that, it was decided to modify existing rail fastening systems to the new track exploitation conditions. When the (re)construction of tram infrastructure is carried out by applying new systems and technologies, it is necessary to take into account their impact on the future propagation of noise and vibration in the environment. This paper gives a short overview of the characteristics of the two newly developed rail fastening systems for Zagreb tram tracks, their application in construction of experimental track section, and performance and comparison of noise and vibration measurements results. Measured data on track vibrations and noise occurring during passage of the tram vehicles is analyzed in terms of track decay rates and equivalent noise levels of passing referent vehicle. Vibroacoustic performance of new fastening systems is evaluated and compared to referent fastening system, in order to investigate their ability to absorb vibration energy induced by tram operation and to reduce noise emission.
