AbstractThe aim of this paper is to present the main advances in the adoption of precision agriculture technologies. While we are witnessing the emergence of a literature dedicated to the adoption of new technologies, this theme still suffers from a lack of consensus on its conceptualization. Based on the prisma statement method (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes), the objective is to carry out a review of the systemic literature in order to identify the main factors of adoption of the technologies of precision agriculture over the past ten years. The results show that individual factors are the most empirically identified as determining factors in the adoption of precision agriculture technologies. That said, the farmer is at the center of the adoption decision. Perceived utility is the factor most identified in the literature as the determinant of adoption.

В работе исследуется процесс разработки компьютеров за последние десятилетия с целью определения наиболее влияющих на него факторов. Описываются сами факторы, которые используются для предсказания направления будущих разработок. Для решения этой задачи применяется концепция Вычислительной Способности, которая позволяет оценить производительность компьютеров теоретически, опираясь исключительно на описание их архитектуры. In this article we are investigating the computers development process in the past decades in order to identify the factors that influence it the most. We describe such factors and use them to predict the direction of further development. To solve these problems, we use the concept of the Computer Capacity, which allows us to estimate the performance of computers theoretically, relying only on the description of its architecture.

Over the past 30 years, a series of inter-related changes in land-use pattern, business arrangements, farm structure, and production practices combined to expand output without increasing the use of total inputs. Moreover, by allowing farmers to increase U.S. agricultural production through increased productivity instead of expanded land and chemical use, many of these innovations helped to limit the impact of agricultural production on the environment. Meanwhile, new technologies (such as precision agriculture) have required additional labor use, a differentiated approach to the specialization of production, and stimulated the concentration of resources, capital and efforts on the production of certain products, which allowed some farmers to increase the size of their operations. As a result, the number of large farms increased 8 times, and their share in the country's agricultural production increased to 62%. Although production has shifted dramatically to larger farms, 97 percent of all farms remain family farms, generating 82 percent of the total value of U.S. agricultural production.

The low adoption of new technologies, particularly improved seeds, remains a critical issue hampering the development of agriculture in many developing countries. The objective of this research is to identify the determinants of (i) the farmer’s knowledge,( ii) the adoption decision and (iii) the adoption intensity of NERICA rice varieties in the Togolese Savannah region. Probit and Tobit models were used to analyse data collected from 150 rice growers randomly selected. The results of the estimations showed that the knowledge, the adoption decision and the adoption intensity of NERICA are determined by socio-economic and institutional factors. The common factors affecting the knowledge, the adoption decision and the adoption intensity are credit access, extension service and gender. However, the adoption intensity is specifically affected by the rice income, the land ownership and the membership to a farmer’s base organization. These findings suggest the necessity to improve the agricultural credit access, the extension services access and to take gender into account in policies making in order to give men and women the same chances of access to innovations.

The construction industry in China has undergone continuous development over the past decades. In relation to this, the quality of the outdoor environment in China has received increased research attention. This paper takes the Tahiti Villas located in Kunming District as a case study, using post-occupancy evaluation to identify and evaluate the main factors affecting the activities of the residents. The results indicate that humanistic design is mainly reflected in the concern for the user exhibited by the design. Thus, giving users primary importance can satisfy the design goals of rational expression.

Представлен анализ динамики численности лося, медведя и волка на территории Кемеровской области (Кузбасса) за последние 70 лет. Максимальных значений численность лося достигала в 1976-1979 гг. (7000 особей), минимальных - в 1994 г. (1850 особей). В настоящее время количество лосей на территории Кемеровской области превысило 5,0 тыс. особей с тенденцией к повышению. Количество медведей в Кемеровской области на протяжении всего исследуемого периода непрерывно возрастает с 300-400 особей в начале 1960-х гг. до 3,0-3,1 тыс. в 2017-2019 гг. Волк на территории Кузбасса находится под жёстким антропогенным прессом. Максимальное количество волков в 400-450 голов отмечалось в 1994-1996 гг., в настоящее время этот хищник практически истреблён, периодически отмечаются заходы 2-7 зверей из сопредельных регионов в зимнее время. Проанализированы основные факторы, влияющие на численность лося: охота, хищничество волка и медведя, качество работы органов госохотнадзора. Показано, что в Кемеровской области количество лося, волка и медведя зависит, в первую очередь, от охотхозяйственной деятельности. Достоверная отрицательная корреляция лося с численностью медведя и волка выявляется только на отдельных временных отрезках, когда она налагается на отрицательное антропогенное воздействие. The analysis of the dynamics of the number of moose, bear, and wolf in the territory of the Kemerovo region (Kuzbass) over the past 70 years is presented. The maximum number of moose reached in 1976-1979 (7000 individuals), the minimum - in 1994 (1850 individuals). Currently, the number of moose in the Kemerovo Region has exceeded 5.0 thousand individuals with an upward trend. The number of bears in the Kemerovo region throughout the study period is continuously increasing from 300-400 individuals in the early 1960s up to 3.0-3.1 thousand in 2017-2019. The wolf on the territory of Kuzbass is under severe anthropogenic pressure. The maximum number of wolves of 400-450 animals was observed in 1994-1996. At present, this predator is almost exterminated. Only 2-7 animals from neighboring regions are periodically noticed in winter. The main factors affecting the moose abundance are analyzed: hunting, predation of a wolf and a bear, and the quality of work of State Hunting Surveillance bodies. The number of moose, wolf and bear in Kemerovo Region depends mainly on hunting activities. A reliable negative correlation of the moose with the number of bears and wolves is detected only in some intervals when it is imposed on a negative anthropogenic impact.

Linearity is a critical parameter to describe positioning errors of touch screens. This paper focuses on a four-wire resistive-type touch screen sensor and tries to find the main factors affecting its linearity. By using the electric field simulation module of ANSYS software, node voltages of conductive layer were analyzed. The mathematical relations between the linearity and individual factors of touch sensor were established and the main factors affecting linearity were identified. Based on optimized sensor parameters, a set of 2.5 inch four-wire resistive touch screen sensors were manufactured and tested with a linearity testing machine. Experimental results show that simulation results and testing results on linearity satisfy the consistency criterion and the analysis results are reliable.

This paper presents optimum sampling levels in discard sampling programs considering cost and precision objectives simultaneously and explores their dependence on both variables. The analysis is based on the Irish discard program: an onboard-observer voluntary sampling scheme aimed at estimating discard rates in trawl fisheries. Multistage analysis was performed to establish the precision levels achieved in the past, and a cost function was determined to estimate the financial cost of the program. Gear, fishing ground, targeted species, and International Council for the Exploration of the Sea (ICES) divisions were the main factors affecting discarding, together with random effects of the three nested groups considered: haul, trip, and vessel. Reductions in the present budget will imply only marginal decreases in precision, although changes in cost variables can have an impact on sampling levels. On the other hand, increasing the target precision by one-half will imply a considerable increase in sampling and associated cost, which will be difficult if not impossible to achieve. Finally, the analysis by fleet components suggests a marked increase in sampling levels, which emphasizes the importance of clearly stated discard sampling objectives.

The purpose of this study is to analyse the environmental benefits of precision agriculture technology adoption obtained from the mitigation of negative environmental impacts of agricultural inputs in modern farming. Our literature review of the environmental benefits related to the adoption of precision agriculture solutions is aimed at raising farmers' and other stakeholders' awareness of the actual environmental impacts from this set of new technologies. Existing studies were categorised according to the environmental impacts of different agricultural activities: nitrogen application, lime application, pesticide application, manure application and herbicide application. Our findings highlighted the effects of the reduction of input application rates and the consequent impacts on climate, soil, water and biodiversity. Policy makers can benefit from the outcomes of this study developing an understanding of the environmental impact of precision agriculture in order to promote and support initiatives aimed at fostering sustainable agriculture.

Background. The organization of clinical trials (CTs) requires the participation and coordination of healthcare providers, patients, public and private parties. Obstacles to the participation of any of these groups pose a risk of lowering the potential for the implementation of CTs. Researchers are a key human resource in conducting of CT. Their motivation for participation can have a significant impact on the recruitment and retention of patients, on the quality of the data collected, which determines the overall outcome of the study. Aims to assess the factors affecting the inclusion of Russian physicians-researchers in CT, and to determine their role in relations with patients-participants. Materials and methods. The study was organized as a part of the Russian multicenter face-to-face study. A survey was conducted of researchers from 10 cities of Russia (20172018). The participation in the survey for doctors was anonymous and voluntary. Results. The study involved 78 respondents. Most research doctors highly value the importance of research for science (4,84 0,39), society (4,67 0,46) and slightly lower for participating patients (4,44 0,61). The expectations of medical researchers are related to improving their financial situation and attaining new experience (n = 14; 18,18%). However, the opportunity to work with new technologies of treatment and diagnosis (n = 41; 52,56%) acted as a motivating factor. According to the questionnaire, the vast majority of research doctors (n = 29; 37,18%) believe that the main reason for patients to participate in CT is to receive quality and free medical care. The most significant obstacle to the inclusion of participants in CT was the side effects of the study drug (n = 38; 48,71%). Conclusions. The potential of clinical researchers in Russia is very high. The patient-participant acts for the research doctor as the subject of the study, and not the object, so the well-being of the patient is not indifferent to the doctor. However, the features of the functioning of our health care system form the motivation of doctors-researchers (additional earnings, professional self-development) and the way they perceive the motivation of patients (CT as an opportunity to receive quality medical care).
