Description
The article examines the degree of economic efficiency of cultural institutions based on the example of the Magadan Municipal Autonomous Institution of Culture "Culture Center" - one of the largest in the city and the region. Current issues are discussed and proposed solutions are highlighted. A five-factor model is used to quantify the effectiveness of the cultural institution's activities, according to the methodology of the Ministry of Culture of the Russian Federation. Several methods for selecting factors in the model are proposed. Applying the model, the coefficient of economic efficiency of the researched cultural object for 2014 - 2016 is calculated and the factors influencing the change of this coefficient are noted. The forecasted estimates of the coefficients of economic efficiency of the Magadan Municipal Autonomous Institution of Culture "Culture Center" for 2017-2019 are calculated taking into account the current trend of a reduction in budgetary financing and a simultaneous increase of income from entrepreneurial and other income-generating activities, as well as a decrease of an economically active population. The article proposes measures to increase the activity, responsibility and effectiveness of budgetary cultural institutions, to expand their independence in the use of various funding channels. This, ultimately, should lead to an expansion of the range of services provided to the population, an improvement in quality and the level of compliance with client requests

Description
Alternation of crops, will remain a fundamental element of zonal technologies of their cultivation for a long time. Application of methods of mathematical model operation will allow to come to new level in the solution of the questions of effective use of an arable land, through application of models optimizing it. Results of researches which basis data of long-term observations are will be especially valuable. They used data of the long-lived stationary experiments on studying of alternation of crops in crop rotations of last more than five rotation. Stationary experiences are located in a forest-steppe zone of Western Siberia on the fields FGBNU "SIBNIISKH". The purpose of researches consisted in optimization of use of an arable land at application of methods of mathematical model operation for preservation of soil fertility. The model allowing when performing particular conditions is given in work (balance of a humus, work expense, a metabolic cost, etc.) to optimize use of an arable land against the background of preservation of soil fertility of the soil, receiving production, economic and power efficiency. It is shown that at alternation of grain crops with clear steam, formation of a harvest happens due to natural fertility of the soil what the negative balance of a humus which reaches 0,18 – 0,78 tons from hectare testifies to. At alternation of field cultures without clear steam the harvest was formed against the background of reproduction of organic matter of the soil, due to increase in vegetable oddments from use of fertilizers, the balance of a humus was positive – 0,15 – 0,28 tons from hectare. Use along with clear steam, busy steam, colza on green fertilizer, and also straw as organic fertilizer for grain crops, 2,01 tons from hectare of commodity grain were received, at a share of clear steam – 16,8%, busy steam – 11%, summer grain – 72,2% of arable land. Increasing in crop rotations of West Siberian Square with use as organic fertilizer of straw, busy vapors and green fertilizers, it is possible to achieve reproduction of fertility of the soil with some decrease in an exit of commodity grain to 2 tons from hectare

Description
The influence of auto-displacement in a resonancetunnel diode (RTD) on the dynamic range of amplifiers on these diodes is considered in the article. The amplification at resonance frequency is considered and the influence of higher harmonics is not taken into account, since they do not create a significant voltage drop at the nonlinear resistance of the diode. It is assumed that the gain will be sufficiently large, and then the nature of the dependence of the gain factors on the degree of regeneration will be the same for amplifiers "per pass" and "reflection". This allows us to consider the problem for both types of amplifiers on the RTD. The types of amplitude characteristics , which are possible for the RTD amplifier, are considered. The dependences of the parameter determining the dynamic range of the amplifier on the position of the operating point for several values of the product of the resistance on the direct current of the supply circuit are calculated for the value of the modulus of the maximum negative conductivity of the tunnel gap RG max. For each value of RG max for given parameters, you can determine the position of the operating point, which provides the specified amplifier mode. Dependences of the value of the dynamic range are constructed with allowance for auto-displacement and in the absence of auto-displacement for two values of the degree of regeneration. Taking into account autosplacement, two possible types of amplitude characteristics and boundaries of their existence were revealed. For these two types of amplitude characteristics, expressions were obtained that determine the dynamic range of the amplifier

SPECIFICS OF AGRICULTURAL PRODUCTION MANAGEMENT SYSTEM
Description
The article deals with the organization of the management of development of agro-economic systems at various levels, assesses the existing approaches to the localization of the management object in relation to agroeconomic systems, points out that agriculture is most often designated as managed subsystems as a part of the national economy, agro-voluntary complexes as territorial-sectoral formations of different levels, cluster type structures, integrated agro-industrial structures and allied other types of agricultural producers, farms of different categories, agricultural production and agrarian potential of rural areas conclude that radical economic reforms have led to the destruction of the agro-industrial complex as a single entity of public administration and transformation of a multilevel system of management of agricultural production and caused the loss of controllability of the agrarian sector, it is pointed out that the restoration of manageability by agricultural production can be it is ensured by consolidating the efforts of all economic agents of agrarian relations: the state (federal, regional and municipal authorities), branch unions and associations, corporate integrated units, consumer cooperatives and economic entities of all categories (agricultural organizations, peasant (farm) households, farms population), describes a set of principles governing the process of forming the management system of agricultural production, the results are given systematization of management tasks, the essence of the management mechanism is revealed, it is proved that, due to the generality of management functions and a certain uniformity of managerial activity, the similarity of information flows ensuring the rational interrelation of subjects and management objects in the process of realizing these functions is observed, and a certain level of typicality of information flows creates objective prerequisites for the formation of a typical system of information support for the management of economic entities of specific types

Description
In the article there were analyzed the different approaches of Soviet and Russian authors to the assessment of soils regarding to agro-ecological factors. There was given the characteristic of natural-economic zones territorially entering the Azov-Kuban lowland by main soil-climatic indexes. There was considered the valuation of soils which determines their relative value and suitability on main factors of natural fertility or their groups, it serves as a criteria of unification of soils into agro-ecological groups. There were shown the main indexes and order of grouping of soils under unification of different soils into agro-ecological groups. There was calculated the “normative” productivity of main agricultural crops on natural-economic zones of Azov-Kuban lowland which defines the agro-productive value of soil. There were revealed the disadvantages of soil assessment method used in the course of state cadastre valuation of agricultural lands asserted by the order of the Ministry of Economic Development from 20.09.2010 № 445. There were cited the specific rates of cadastre cost (SRCC) of agricultural lands on municipal entities of Krasnodar region. There was given the assessment of obtained data regarding to natural-climatic factors of the region, there were made proposals on optimization of trends of further researches on claimed problem

Description
Production and processing of grains have formed a number of cereals-governmental sectors in the national economic system of the country, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and the role of the grain as a commodity in the state economy can not be overestimated. This product is totally liquid; it has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortage was covered by imports. According to the characteristics of management in agriculture, it should be especially emphasized that the lack of objective and timely information at all stages of crop production, and, as a consequence, the adoption of suboptimal management decisions, leads to the fact that labor and material resources increase substantially, the enterprise receives less profit , and sometimes incurs losses.When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the task of developing and implementing a specialized software package for the task of managing technological processes in crop production with the goal of improving the quality, efficiency and validity of management decisions

Description
The transportation process plays an important role in the delivery of agricultural products to the consumer. On how well the fruits are preserved, their grade will depend, and, consequently, the price of them. It is known, that the annual damage from losses of agricultural products in the agro-industrial complex amounts to 8 billion rubles, according to various estimates. A large number of different factors affect the safety of fruits during transportation: temperature, humidity, smoothness of the vehicle, type of container, etc. The more factors will have a negative impact on fruit and vegetable products, the more losses will ultimately be. The appearance of dents and abrasions on the fruits gives rise to the formation of foci of rot, leading to damage to the transported products, and, as a consequence, reducing the grade. In order to reduce the losses of fruit and vegetable products in the process of transportation, the USSR and the Russian Federation have been and are working on the creation of containers and ways of transporting pomegranates. All of them, according to the authors, are able to reduce the dynamic loads that arise during the transportation process and have a negative impact on the transported products. However, due to various circumstances in commercial gardening all these developments have not been extended
