An Assessment of Selected Work Organisation Variants in an Underground Hard Coal Mine with Consideration to Unit Mining Costs

The aim of the paper is to compare two forms of work organisation, the first of which assumes extending the mine’s operation fromfive to six days a week, and the other – implementing a continuous work organisation system. To illustrate this in terms of unitmining costs, a model hard coal mine was used. In addition to the current organisational solution, which serves as the startingpoint for comparative analysis, solutions were proposed to increase the degree of utilisation of the existing production potential,mainly with regard to technical means of production and human resources. The proposed solutions assume increasing the intensityof use of technical means of production on an annual basis by extending the annual working time of selected mining crews. For thecomparative analysis, three variants of the mine’s operation in terms of the production organisation system were adopted. UnderVariant I, treated as the baseline option, the current organisation of production is to be continued (5 days a week, Monday to Friday,excluding public holidays). Variant II provides for extending the working time of some mining crews to 6 days a week (fromMonday to Saturday, excluding public holidays). Variant III assumes continuous operation for 7 days a week (excluding publicholidays and several days for shaft inspections). Having adopted appropriate baseline assumptions for simulation calculations anda set of input data reflecting the characteristics of a specific mine, simulation calculations were performed and their results wereused to carry out a comparative analysis of selected organisational solutions.

Calculation Model of Railway Capacity Price in the Czech Republic

This paper presents a pricing model of railway infrastructure capacity allocation functioning as a regulatory measure while fulfilling the regulatory requirements on railway infrastructure capacity allocation. The prices of railway infrastructure capacity allocation will be modelled with regard to all economically justifiable costs of railway infrastructure capacity allocation. The structure of model has been developed as a set of calculation sheets in Microsoft Excel. The recommended prices for railway capacity have been found by simulation of a set of variants and the recommendation is done for different operational conditions in an individual way. It analyses different products offered by the railway infrastructure capacity allocator both in the annual working timetable mode, and in the individual ad hoc mode. The aim of the proposed model is to motivate not only railway undertakings, but also the railway infrastructure capacity allocator to submit requests for railway infrastructure capacity in the annual working timetable mode rather than in the individual ad hoc mode. The total price is then verified to the cost of railway infrastructure capacity allocation. This process then ensures the regulation of the demand of railway undertakings on the given route and can influence the decision about the use of the product offered.

Impact of different factors on the farmers' decision to insure crop production

The aim of the paper is to consider and analyze the impact of subsidies levels and other economic and general factors on the farmers' decision to insure their crops. The paper applies the model of logistic regression in order to determine the statistically significant influence of certain factors on the decision of farms. The subject of the research is general and economic data from agricultural holdings in the FADN sample in Serbia for 2018. The sample includes farms that deal with specialist field crops, specialist grazing livestock and mixed crops-livestock production. The survey was conducted on a sample of 819 households, of which 99 households reported insurance costs (12.1%). The results of the research show that with higher subsidy level the probability that farms will insure their production reduces. On the other hand, with an increase of economic size and farm net value added per annual working unit the probability that farms will be insured also increases.

La reducción de jornada anual en un sector de nueva creación. Ni aplicación del convenio, ni condición más beneficiosa: falta de acción. Comentario a la sentencia de la Audiencia Nacional, Sala de lo Social, 128/2019, de 31 de octubre

<p>Un conflicto colectivo de enjundia, como el derivado de la operatividad de una condición más beneficiosa en materia de jornada anual en supuestos de sucesión de convenios, obediente a la aparición de un nuevo sector nacional por mor de la especialización técnico-productiva, encuentra respuesta judicial de remisión a su sede apropiada al apreciar la excepción de falta de jurisdicción, de límites tan polémicos como su propia aplicación en el caso concreto.</p><p>A relevant collective conflict derived from the operation of a more beneficial condition in terms of the annual working hours is analysed. This, in addition, in cases of succession of collective bargaining agreements and due to the emergence of a new national sector for the sake of technical-productive specialisation. Judgment refers to its appropriate headquarters upon observing a exception of lack of jurisdiction, with limits as controversial as its own application in the specific case.</p>

ESTIMATION OF WORKLOAD OF ANMS AND CALCULATING THE REQUIRED NUMBER OF ANMS IN IMPLEMENTING MOTHER CHILD TRACKING SYSTEM IN NORTHERN INDIA: WISN METHODOLOGY

Mother child tracking system(MCTS) is an information system for tracking maternal and child health beneficiaries in Indias public health system, and improving service delivery planning and outcomes. Auxiliary nurse midwife(ANM) has broad spectrum of responsibilities to play in under National health mission. In the present study the workload of ANM was estimated using standard methodology WISN(Workload indicators of staffing needs) given by WHO. Quantitative research approach with time-motion research design was chosen for the study. Workload was estimated in 21 civil dispensaries of Chandigarh, India. The workload was found to be high in 9 dispensaries. It was very high in 4 dispensaries where ANMs spent their total annual working time in doing activities under MCTS and they are left with no time for doing activities under other national health programs.

Methods developed during the first National Center for Biotechnology Information Structural Variation Codeathon at Baylor College of Medicine

In October 2019, 46 scientists from around the world participated in the first National Center for Biotechnology Information (NCBI) Structural Variation (SV) Codeathon at Baylor College of Medicine. The charge of this first annual working session was to identify ongoing challenges around the topics of SV and graph genomes, and in response to design reliable methods to facilitate their study. Over three days, seven working groups each designed and developed new open-sourced methods to improve the bioinformatic analysis of genomic SVs represented in next-generation sequencing (NGS) data. The groups’ approaches addressed a wide range of problems in SV detection and analysis, including quality control (QC) assessments of metagenome assemblies and population-scale VCF files, de novo copy number variation (CNV) detection based on continuous long sequence reads, the representation of sequence variation using graph genomes, and the development of an SV annotation pipeline. A summary of the questions and developments that arose during the daily discussions between groups is outlined. The new methods are publicly available at https://github.com/NCBI-Codeathons/, and demonstrate that a codeathon devoted to SV analysis can produce valuable new insights both for participants and for the broader research community.

Enterprise growth simulation model

Simulation mathematical model of small enterprise functioning is under analysis in this article. It is assumed that annual working capital profitability and loan rate are random variables with normal distribution, the amount of borrowed capital does not exceed the amount of own working capital. Given the value of its working capital at the beginning of time, its dependence on time is constructed as a random process. The parameters of random variables are estimated based on the processing of statistical data on the previous activities of this enterprise. The implementation of the random process is statistically modeled. With the help of the statistical tests, implementations of random function of growth of own working capital are built and the probability of bankruptcy is estimated as relative frequency of cases of adoption of negative value by random function. It is proposed to use the built simulation model of the enterprise to estimate the probability of bankruptcy of the studied enterprise in the coming period (a given number ofyears).

Productivity in Mechanizing Early Tending in Spruce Seedling Stands

According to National Forest Inventory data, there is an urgent need for tending seedling stands of at least 700,000 ha and a need for 1 million ha in the next few years in Finland. The motivation for forest owners to conduct pre-commercial silvicultural operations is low due to the associated high costs. Especially the costs of tending and clearing operations after the regeneration of the stand have been increasing. In addition, the availability of labor is a restricting factor due to the high seasonality of silvicultural works. In the 2000s, several solutions for the mechanization of tending have been proposed. These are based on the use of harvester or a forwarder as a base machine. Typically, light weight base machines are favored to reduce the hourly cost of operations and the impacts on the remaining seedlings. There have been challenges with the high speed of the cutting device, which increases the risk of damages to the head and the ignition of forest fires when the circular saw or chain hits stones, for example. In addition, the chain can become dislocated due to bending forces caused by stumps. Cutlink has presented a low RPM solution based on rotating cone-shaped shears that cut 50–100 cm wide corridors between and around seedlings. In this study, the productivity of mechanized tending with Cutlink´s device compared to manual tending was evaluated in spruce seedling stands in central Finland. The productivity, fuel consumption and quality of the seedling stand after the operation were measured. In early tending, the productivity of motor manual tending was notably better than when using the Cutlink device. Crucial factors for the competitiveness of a mechanized alternative include the annual working hours and finding suitable working areas for the machine. Additional work for the device and base machine can also be found in the clearing of forest road sides.
