An accurate use of the ability to steer computer efficiency is essential from the database point of view. Effective resource allocation is dependent on the performance indicators gathered from running systems. There must be an appropriate balance between accurate measurements, performance indicators and speed of the reallocation algorithms of the computing resources. The extended measurement of efficiency which the authors propose for applications is: the average number of queries within a time unit for particular groups of users. This paper presents an analysis of using the Workload Manager utility in the AIX 5L operating system to improve the efficiency of applications in the MySQL database environment, and an analysis of methods which allows the use of Workload Manager for steering efficiency dynamically.

Labor absenteeism is a factor that affects the good performance of organizations in any

part of the world, from the instability that is generated in the functioning of the system.

This is evident in the effects on quality, productivity, reaction time, among other aspects.

The direct causes by which it occurs are generally known and with greater reinforcement

the diseases are located, without distinguishing possible classifications. However, behind

these or other causes can be found other possible factors of incidence, such as age or sex.

This research seeks to explore, through the application of neural networks, the possible

relationship between different variables and their incidence in the levels of absenteeism. To

this end, a neural networks model is constructed from the use of a population of more than

12,000 employees, representative of various classification categories. The study allowed the

characterization of the influence of the different variables studied, supported in addition to

the performance of an ANOVA analysis that allowed to corroborate and clarify the results

of the neural network analysis.

In recent years, the outsourcing of a variety of different activities has been more commonly observed in the coal mining industry. This is connected with employing workers by external companies. These practices are not necessarily perceived as good ones by mines’ employees because they may influence their remuneration directly or indirectly. Firstly, as external employees treat work in mining company as a source of a quick income. Therefore, external companies often calculate their employees compensation not based on working time (i.e. hours) but on the basis of a specific, accomplished task. Such employment is called piecework, whereas the workers employed in this kind of system are called output workers/piece workers. Therefore, to receive higher wages in these companies, employees carry out their tasks faster and more efficiently. This, in turn, can affect the standards of workers employed by the mining company. In addition, outsourced workers are often retired miners, so the costs incurred by employers are significantly lower. In addition, in order to not to lose the retirement benefit, they work for a much lower rate. On the other hand, outsourced work can be done in a hurry (on a piece rate), which is not conducive to compliance with safety regulations, therefore mine employees may feel unsafe. This article aims to present how mine employees assess outsourcing underground works. In order to achieve this aim, a survey was carried out among employees of one of the coal mine companies in Silesia. Participants of the survey were randomly chosen among underground miners employed at one mine company. The survey was anonymous which obviously might have influenced respondents’ honesty in answering. The survey was carried out in several mines of the chosen company. In some of them the survey was carried out online and in the remaining ones it was filled out on paper. Analyzing the survey results allowed for a better understanding of the reasons of the disapproval of outsourcing underground works. This, in turn, may be used for better human resources management including, in particular, planning an incentive based pay system.

The article presents the principles of sozology formulated by Walery Goetel and examples of their development in the scientific and research works as well as implementation and teaching work performed at the Faculty of Civil Engineering and Resource Management at AGH University of Science and Technology. These works are aimed at the rational management of mineral deposits and its extraction, as well as at the creation of utility values of the post-mining areas. It has also been shown that the work carried out at the faculty has gone far beyond mining activities using the experience gained from them. This has included, for example, the preservation and accessibility of the subsoil of medieval towns and the revitalization of towns with a predominantly industrial character. Work has also been conducted to rehabilitate sites and facilities for additional public use.
The most important directions of solutions in the field of the reclamation and revitalization of post-mining areas developed with the participation of the faculty staff as well as in cooperation with national and international researchers are in this article. The continuous development of the Faculty is also reflected in its name changes: from the Faculty of Mining, through the Faculty of Mining and Geoengineering, to the Faculty of Civil Engineering and Resource Management. The current name reflects the actual scope of the subject matter undertaken in research and teaching, specifically the management of natural mineral deposits and also of secondary resources that should be reused in a closed cycle.

The paper presents the problem of the growing water deficit and the possibility of sustainable development of water resources in rural areas of Central and Eastern Europe (using the example of Poland). It is estimated that the amount of resources in this region is reduced by about 70% compared to the average for Europe. In drought periods it comes to limitation of economic activity, including agriculture. Particular attention was paid to the necessity to extend landscape, underground, and snow retention, as an alternative to dams, which are currently the most popular in lower-order catchments. It has been shown that the construction of small agricultural reservoirs is not always preceded by adequate consultations and pre-design studies, which may result in financial losses and legal problems. Simultaneous use of many alternative forms of retention should be more effective than the implementation of reservoirs. In addition, increasing the hydraulic roughness of the catchments slows down the outflow of products of erosion and contributes to the protection of surface retention structures (maintaining natural and economic usefulness of reservoirs).

A large amount of research has shown that there are two types of trait content in social cognition – agency (including competence) and communion (including morality). Because communal traits are more instrumental in locating a person on the approach-avoidance dimension than agentic ones, the former are considered to be relatively more important in person (and group) perception processes. We developed a proposal that this difference in importance extends to spontaneous trait inferences based on the behavior of the perceived person. The hypothesis that trait inferences are stronger in the communal than agentic domain was tested in four experiments (N = 265) using three different methods of studying spontaneous trait inferences (i.e., the cued recall of distractors procedure, the false recognition paradigm, and the lexical decision task). Despite the variation in methods, the studies yielded the same result – spontaneous trait inferences appeared stronger in the communal than agentic domain, but the effect was restricted to the traits of positive rather than negative valence. For the agentic domain the strength of trait inferences remained relatively low, independent of trait valence. Possible reasons for the difference between positive and negative communal traits are discussed.

The proper management of water resources is currently an important issue, not only in Poland, but also worldwide. Water resource management involves various activities including monitoring, modelling, assessment and designing the condition and extent of waters sources. The efficient management of water resources is essential, especially in rural areas where it ensures greater stability and efficiency of production in all sectors of the economy and leads to the well-being of the ecosystem.
The performed analyses have demonstrated that the time of origin of the cadastral data defining the course of water boundaries has a significant effect on their quality. Having analysed the factors (timeliness, completeness, redundancy) used to assess the quality of cadastral data, their clear trend of changes in time was noticed. Thus, it is possible to specify the estimated degree of quality of cadastral data defining the course of watercourse boundaries only based on the information about the method, time and area of data origin in the context of the former partition sector.
This research paper presents an original method of assessing the quality of spatial data that is used to determine the course of the shoreline of natural watercourses with unregulated channels flowing through agricultural land.
The research has also demonstrated that in order to increase the efficiency of work, the smallest number of principal factors should be selected for the final analysis. Limiting the analyses to a smaller number of factors does not affect the final result, yet it definitely reduces the amount of work.

The article presents aspects of the legal characterization and regulation of the natural resource’s treatment that are under the joint tenancy of two or more states. The scientific novelty of the study is determined by that fact that shows the aspects of international interaction and the formation of the practice of legislative regulation of the use of natural resources, not only in the field of state and legal regulation but also within the context of private-public partnership. The relevance is determined by the fact that the main problem of the development of energy resources is an opportunity to determine and accordingly implement certain provisions for international business enterprises. The purpose of this article is to study the question of how representatives of international business can implement projects for the extraction of natural resources across boundary areas and under various conditions within the framework of cross-border cooperation. In the work, the methods of mathematical statistics, historical and legal methods were used. A three-level model was presented. This model determines the possibility of ensuring cooperation, then it forms its legal and regulatory framework and then determines instruments of an economic and legal nature that can be implemented in this field. The final point of the model is the finding of opportunities for investing in the development of natural energy resources on a parity basis, as well as the formation of an integrated environment that determines the possibility of integrating the subjects of international business into the economic environment of the state.
