The Impact

In the residential area under the impact of emissions from non-ferrous metallurgy and woodworking industry, the quality of atmospheric air was shown to fail to meet the requirements of hygienic standards for the content of suspended solids in air [≤ 4 MPC for maximal single dose (MPCmsd), ≤ 12.5 MPC for average daily dose (MPCadd), phenol (≤ 5.6 MPCmsd, ≤ 4.83 MPCadd), formaldehyde (≤ 1.56 MPCmsd, ≤ 6.58 MPCadd), fluoride gaseous compounds (≤ 3.75 MPCmsd, ≤ 12.4 MPCadd), etc. The quality of potable water in the centralized water supply system from surface water source corresponds to hygienic standards but, and in drinking water from the underground water source hygienic standards of iron content are exceeded (up to 1.1 MPC, 3.6% of samples). Also, in the study area, exceedances of permissible concentrations in lead soils are observed up to 2.09 MAC (7.84% of samples) and fluorine up to 4.68 MPC (87.04% of samples). The individual carcinogenic risk for the children of the study area is, on average, 1.18 ∙ 10-3, for the adult population, an average of 5.25 ∙ 10-3, and exceeds the acceptable level of carcinogenic risk by about 52.5 times. The individual non-carcinogenic risk for the short-term exposure to chemicals is by up to 9 times higher than the acceptable level. The individual non-carcinogenic risk for the chronic multimodal intake of the studied chemicals exceeds the permissible value of the total hazard index by to 33.4 times with respect to respiratory disorders. Priority factors that determine the level of risk to public health are chemicals present in emissions from enterprises producing primary aluminum (Benz(a)pyrene, fluorides, sulfur dioxide, suspended substances) and cellulose (phenol, methyl mercaptan).

Significant Factors

Sustainable mobility is becoming a key factor in improving the quality of life of the residents and increasing physical activity (PA) levels. The current situation of sustainable mobility and its analysis is a first step in understanding the factors that would encourage residents to discover and choose alternative modes of travel. The present study examined the factors that encourage the choice of active modes of travel among urban adult population. Walking and cycling were analyzed as the most sustainable forms of urban mobility from the perspective of car and public transport (PT) users. Total of 902 subjects aged 18 years or older were analyzed in the study to assess commuting habits in Kaunas city, Lithuania. The majority (61.1%) of the respondents used a passenger vehicle, 28.2% used PT, and only 13.5% used active modes of travel. The results showed that safer pedestrian crossings, and comfortable paths were the most significant factors that encourage walking. A wider cycling network, and bicycle safety were the most important incentives for the promotion of cycling. Our findings show that the main factors encouraging walking and cycling among car and PT users are similar, however, the individual characteristics that determine the choice of these factors vary significantly.

Purpose – This paper aims to add to the understanding of knowledge sharing in online communities through an investigation of the relationship between individual participant’s motivations and management in open source software (OSS) communities. Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach – To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents’ opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings – The analysis of the data reveals that the individual participant’s satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value – Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members’ satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.

Culture And Climate

The impact of Globalization creates a competitive horizon with new markets, new products, new mindsets, new competencies, and new ways of thinking about business. As an outcome of this, the market places become more complex, uncertain, competitive, and transformational. In this era, the major challenge faced by any organization is to maintain a peaceful as well positive culture and climate inside the organization. The human resource development climate of an organization plays a significant role in ensuring the competency, motivation, and development of its employees. Here the term climate denotes the quality of the internal environment. It influences morale and the attitudes of the individual toward his work and his environment. Culture refers to the deep structure of organizations, which is rooted in the values, beliefs, and assumptions held by organizational members. The study was aimed to analyze the Human Resource Development culture and climate of chemical-based public sector enterprises in Kerala. The results indicated that the Human Resource Development climate in an organization is average and the perception of employees regarding Human Resource Development culture and climate does not differs significantly based on age, job approval status, and qualification. But it differs significantly based on gender and experiences.

Ntroduction. The assessment of water quality and safety of centralized water supply systems in the Primorsky Krai was carried out in order to assess hygiene levels of public health risks associated with drinking water from the distribution network. Material and methods. The data of laboratory studies on sanitary and chemical parameters in drinking water of the distribution network of the Primorsky region were used. Hygienic assessment of drinking water was carried out according to regulatory requirements, the effect of summation of biological effect was calculated. The work used methodological recommendations for calculating the index of chemical water pollution and the utility coefficient, as well as a guide for assessing the health risks of the population when exposed to chemicals of a non-carcinogenic and carcinogenic nature. Non-carcinogenic and carcinogenic risks were calculated for all potable water of centralized water supply based on the average daily intake dose and the reference dose of chemicals supplied with drinking water. The risk profile for carcinogenic and non-carcinogenic effects was achieved by comparing exposure levels with reference concentrations (safe) for human health. The risk profile for the combined effects of chemical compounds is based on the calculation of the hazard index (HI). A study on carcinogenic risk was carried out for substances that are identified as carcinogens according to the classification of an international agency for the study of cancer. For the analysis and statistical processing of information, the program "MS Excel" was used. Results. An assessment of the sanitary and epidemiological safety of centralized systems of domestic and drinking water supply in the region showed that the highest contribution to poor health is made by the content of arsenic, nitrates, iron, silicon, and petroleum products in drinking water. According to the values of hazard indices, the skin and mucous membranes, the central nervous system, the immune system, the endocrine system, the circulatory and digestive organs are exposed to adverse effects from chemicals in drinking water. The individual carcinogenic risk ranges from negligibly small to the upper limit of acceptable carcinogenic risk. Assessment of the potable water value indicator revealed a deficit situation in calcium, sodium, fluorine and general mineralization of water. The risk assessment for arsenic, tetrachlorethylene, and chloroform, which have carcinogenic properties and are the most important pollutants of drinking water, has shown that the individual risk levels for these substances are within the first and second ranges, which corresponds to the allowable and maximum allowable risk. Discussion. Arsenic concentration in adults was found to be not detected with risks greater than one, while for children, the non-carcinogenic risk from arsenic exceeded the level of safe exposure (HQ> 1), because children are more susceptible to toxic substances due to their relatively large volume of respiration and the rate of gastrointestinal absorption (due to greater permeability of the intestinal epithelium), and also due to the immature system of detoxification enzymes and a relatively lower rate of excretion of toxic chemicals. According to the level of non-carcinogenic risk for children, nitrates follow arsenic. Nitrates have a hypoxic effect, increasing the concentration of the irreversible form of hemoglobin - methemoglobin. The toxicity of nitrates is related to their transformation into the human body into nitrosamines. As a result, the child's organism responds more sharply than in adults to the presence of chemicals in the water. The general mineralization of drinking water is one of the integral index of the quality of drinking water. Calcium and magnesium deficiency can be an independent risk factor for the development of various diseases and manifest pathologies of the cardiovascular system: coronary heart disease, hypertensive disease, myocardial infarction, etc. The tap water is known to be is not overloaded with carbonates, since they can lead to spoilage of water pipes. Therefore, to enrich the water with calcium and magnesium, the technology of creating bottled water uses mineral additives, which means that such water can become an additional source of minerals. Conclusion. Sanitary and hygienic assessment of centralized systems of domestic and drinking water supply in the Primorsky Territory has shown that the quality of drinking water depends on the concentration of arsenic, nitrates, iron, silicon and petroleum products. It should be noted that with the daily use of water from the distribution network throughout life, the likelihood of developing harmful effects on the health of adults and children is insignificant.

Water is the substance that made life on Earth possible. It plays a key role in both the individual and population development of all species. Water is also a critical resource for humans as populations continue to grow and climate change affects global and local water cycles. Water is a factor limiting economic development in many regions of the world. Under these conditions, good water quality becomes an extremely important factor that determines its economic utility, including water supply, recreation, and agriculture. Proper water quality maintenance of freshwater ecosystems is also very important for preserving biodiversity. The quality of water depends on many factors, the most important of which are related to human impact on water ecosystems, especially the impact of various pollutants from municipal economy, industry and agriculture. Hydrotechnical changes, such as river damming, drainage processes and water transport between catchments also have a significant impact. Water quality is also dependent on the impact of natural conditions connected, e.g., with climate, catchment, water organisms and their interactions within the food-webs, etc. This Special Issue consists of fourteen original scientific papers concerning different problems associated with the water quality of freshwater ecosystems in a temperate climate. Most of the articles deal with the relations between water quality and the structure of ecosystem biocenoses. The conclusion of these articles confirms the fact that the deterioration of water quality has a direct impact on the quantitative and qualitative structure of biocenoses. This is accompanied by a decline in biodiversity and the disappearance of rare plant and animal species. They also draw attention to the particular importance of internal physical and chemical differentiation within the aquatic ecosystem, both in horizontal and vertical dimensions. The problem of ensuring proper ecological conditions and good quality of water in freshwater aquatic ecosystems is also raised, and methods for the restoration of water bodies are presented. The majority of the research presented in this Special Issue was carried out in Central Europe, and one of the papers concerns the area of West Africa—the edge of temperate climate zone.

Marine traffic can be defined as the combination of individual ship movements in a specified area and the ‘quality’ of marine traffic depends in the first place on the human and technical quality of the vessels participating. The second important situation is in the rules and regulations by which the individual vessels are bound. In some areas these two conditions seem inadequate to guarantee an acceptable level of marine traffic safety. An adequate yardstick by which to measure this level of safety is however still lacking.
