The Relationship

The article discusses a non-standard view of the formation of human capital for work in organizations of the agricultural sector of the economy, in the context of modern socio-economic transformations. In the classical sense, human capital for agriculture should be formed and developed in rural areas. But in real life, this is not always the case, because there are many factors that prevent the classical solution of this problem. First, the demographic factor affects, second, social and household factors, and third, in many rural areas there are no working agricultural organizations where qualified agricultural specialists can work. All these and other circumstances actualize the problem of the quality of human capital in rural areas in relation to the development of agricultural production.

This work aims to evaluate the quality of drinking water in the communities of Baiacu, Sao Francisco do Conde, Santo Amaro and Cachoeira. It was verified that in some places of Santo Amaro and Sao Francisco do Conde, from the microbiological point of view, it is not appropriate for consumption, because it was found that the presence of total coliforms in 50% of the samples and that the chlorine content is below the values indicated by the standards in 75% of the analyzed samples. Thus, the consumption of contaminated water can cause diseases, so it is recommended cleaning of residential reservoirs, maintenance in pipes periodically, as well as the need for continuous monitoring of water quality and the intense participation of public agencies in these actions. Through these actions and the active participation of the population, one can preserve the environment and the lives of all those who transit in the communities of the Bay of All Saints

The Sunamganj district is covered by major Haor systems in the north-eastern region of Bangladesh. Flash flood is the most commonly occurring water related disaster in the Haor areas. During the flash flood it is very common that people lost their primary agricultural productions which are the only source of their livelihood. The present study focuses on the effects of 2017 early flash flooding on rice and fish production of Sunamganj Haor areas. The flood caused enormous damage to agriculture such as rice especially Boro rice and fish production on which the Haor dwellers rely upon for their livelihood. The total affected land of Boro rice cultivation in Haors of Sunamganj was 149,224 hectare and the total amount of damaged rice was 393,855 metric ton (MT). The total number of affected farmers was 315,084. The early flash flood also affects the quality of Haor water which caused the death of fishes. The total amount of damaged fish was 49.75 MT and the loss was 158.70 lakh taka. The total number of affected fishermen was 44,445. This findings could be very useful for the environmental scientists to predict the probable future effects on agricultural production due to early flash flood events in Sunamganj Haors areas.

Recent Outbreak

Zimbabwe’s urban areas are choking under the weight of over-crowdedness amidstdilapidated infrastructure that is characterised by constant service failure. The water andsewer systems of the country’s major urban centres are on the verge of collapse, thusputting millions of people in danger of consuming contaminated water, including thatfrom underground sources. Waste management and water supply problems manifestthemselves as challenges bedevilling many an urban area in the country. The quality andquantity of water supplied in Zimbabwe’s urban centres has plummeted in recent yearsand has assumed crisis proportions owing to the difficult economic situation and otherchallenges faced by the country. The situation is desperate and dire, as is evidenced by thepoor quality of delivered water, severe water rationing and the outbreak of water-bornediseases in the urban areas dotted across the country. The situation demands and dictatesthat solutions be proffered as a matter of urgency.The recent outbreak of epidemics hasbeen blamed on lack of access to safe water and poor sanitation, two crucial factors incontrolling the spread of diseases. An overly bureaucratic environment, where decisionsand processes take longer, makes life complicated for poor urban residents. Such ascenario motivated the researchers to examine the problem with a view to suggest waysand means of intervening to mitigate and resolve the problem. It emerged from thefindings that the problem is multifaceted in nature, hence a whole range of measures needto be adopted if a long-term solution is to be provided.

Aim: To evaluate the effect of irrigation techniques, i.e. different types of irrigation needles, on the quality of cleaning of root canal walls using scanning electron microscopy (SEM). Material and Method: The study was conducted on 16 extracted, single-rooted, human teeth. The samples were allocated to two experimental groups depending on the type of the irrigation needle. Conventional needles were used for the irrigation of Group I and laterally perforated ones for Group II. All root canals were instrumented using K files and the Step-back technique. During instrumentation, all samples were irrigated with 2.5 % sodium hypochlorite solution followed by final irrigation with 17 % EDTA for 1 min. After that, all samples were irrigated with 10 ml of distilled water. The roots were, then, sectioned longitudinally and middle one third of each root canal was analyzed using SEM. Quantitative analysis was based on criteria by H?lsmann et al. Results: The obtained results showed that the more efficient removal of debris and the smear layer was accomplished in the group of samples irrigated using laterally perforated needles than conventional needles. The difference between the investigated irrigation techniques were statistically significant (p<0.01). Conclusion: The use of laterally perforated needles for irrigation allows more efficient cleaning of root canal walls, i.e. the removal of debris and the smear layer.

Organic Products

Organizational production of agricultural products is used to preserve the natural environment and to preserve the quality of the products. The development of organic wines in the light of 100 years and over the course of the period has become insane, as for the correct organization of it, you can preserve ecological, social, and commercial transfers. The organizational structure has become a warehouse part of the bio-economy and circular economy, which is a priority for the economic development of the European Union, the USA, Great Britain, the Great Britain, the Republic of Korea, Japan, and the United States of America. For determining the prospects and problems of organic production of agricultural products, general scientific methods were used such as publicity, systematization, analysis, and synthesis, of the scientific literature and normative documents. For an additional analysis of regulatory documents, a procedure for certifying the authorities of the United States, the European Union and Ukraine has been established. Ukraine, in turn, began to take the first steps towards organic production in the late 1990s. It was at this time that she began to grow organic grain and opened export lines for its transportation to other countries, mainly Europe. Ukraine remains a leader in the production and export of organic cereals. Export competitive advantages of national agar products are lower production costs and logistics support. Ukraine continues to increase its organic production capacity - an increasing number of operators are appearing in this sector of agricultural production. As of 2019, the share of organic production of crop products in Ukraine is 1.4% (5th place in the world in terms of growth rate of organic agriculture), which is 467.9 thousand hectares of the total area of agricultural land in 32, 7 million hectares, as well as 470 operators of organic production. The dynamics of changes in organic agricultural production in Ukraine indicates a general trend of increasing their number, but in some periods, there is a decrease due to the economic and political situation in the country and changes in legislation in this area. Ukraine has significant advantages of organic production, which include a high level of soil fertility, favorable climatic conditions, traditional orientation as an agrarian state. Also, the price of Ukrainian products is lower than the minimum price of organic products of European countries. In the organic production of crops use methods that optimize the biological activity of soils, provide a balanced supply of nutrients to plants. At the same time, there are problems in Ukraine that hinder the development of organic production. In particular, the diversity of the territory in terms of the level of pollution of environmental components, lack of practical application of innovations and modern technologies of agricultural production. The lack of state support for organic producers and state certification system (including qualified specialists for its implementation). Resolution of the Cabinet of Ministers of Ukraine of October 21, 2020, № 1032 "On approval of the Procedure for certification of organic production and / or circulation of organic products and amendments to the resolution of the Cabinet of Ministers of Ukraine of October 23, 2019, № 970" approved the stages of certification. Was made the comparison of approaches to the certification of agricultural enterprises in Ukraine shows that they meet European and American standards. However, the absence of a state certification body that certifies organic producers and accredits private certification bodies makes it impossible for state control over organic market operators and the functioning of state certification. The current certification system in Ukraine does not cover the issue of soil contamination or other components of environment, which may affect the quality and safety of organic products. In Ukraine, enterprises in various sectors of the economy use outdated technologies, which can cause soil contamination of agricultural lands, and, accordingly, affect the quality of organic products. Currently, the Laws of Ukraine and the Cabinet of Ministers do not require: the location of the organic agricultural enterprise; content of harmful substances in the soil (including the content of radionuclides and pesticide residues); content in the soil of nutrients that can ensure the production of quality agricultural products and confirm the activities of the farm aimed at maintaining soil fertility. To guarantee the quality of organic products, it is advisable in the certification procedure to consider the level of fertility and soil contamination of agricultural lands, as well as the availability of sources of environmental pollution in the location of the organic producer. Given the above, it is advisable to introduce criteria for assessing the compliance of soils with the requirements of organic production. This approach can guarantee the safety and quality of organic products. During the organization of organic production of agricultural products in Ukraine, the issues of criteria for assessing compliance with regulatory requirements, documentation to be kept by the operator of organic production, etc.
