Opis:
The climb is the steep fragment of the road. In road cycling, climbs should be categorized by the effort necessary to overcome it. Two values have the greatest influence on a difficulty of the climb: its average slope (rise/run ratio) and length. A simple approach to describing a climb's difficulty is multiplication slope squared and run. In this paper, the beginning of the climb is mathematically established to get the most reliable difficulty index. Moreover, it is presented a special case where the value of difficulty index does not depend on the location of the beginning point.

Opis:
The paper presents the calculations of the Management Difficulty Index (STG) for forest ranges in the State Forests. The calculations were made on the basis of the characteristics of the management conditions and the scope of tasks for all forest ranges in the country in 2009. The usefulness of the STG index was proven in the management practice of the State Forests.

standardization of administrative costs
Opis:
The paper presents the results of the standardization of administrative costs of forest districts using the Management Difficulty Index (STG) for forest districts. It discusses the basis for the structuring of the STG for forest districts as well as standardization of administrative costs of the regional directorates of the State Forests using the source data from 2014. The source data for the administrative costs incurred by forest districts as well as the data on natural−forest conditions and annual economic tasks of forest districts were obtained from the State Forests Information System database for all forest districts in the country, the Bureau for Forest Management and Geodesy and the Forest Data Bank. Information on the social environment of forest districts was obtained from the Local Data Bank of the Central Statistical Office and the data on the number of cases of theft and damage to forests directly from forest districts. The obtained results indicate that the index value calculated for the regional directorates of the State Forests (RDSF) was determined by the number of subordinate forest districts and index values obtained by them. The highest STG value in 2014 was reported for: Katowice RDSF – 153.43, Szczecin RDSF – 145.2 and Wrocław RDSF – 128.7 points. The lowest STG value was recorded in the Warsaw RDSF – 49.39, Kraków RDSF – 53.14 and Gdańsk RDSF – 64.02 points. The calculated differences between the total administrative costs incurred by forest districts and the total standard administrative costs calculated on the basis of the mean value of 1 point of STG for forest districts in the State Forests for 2014 allowed dividing the regional directorates of the State Forests into two groups. The first one consists of 10 regional directorates, whose total actual administrative activity costs were lower than total standard administrative costs (negative values). The other group consists of 7 regional directorates, whose total standard administrative costs were lower than actual costs incurred in 2014 (positive values). STG indices for forest districts can be successfully used to standardize the total costs of forest districts. They should be a helpful tool in developing more objective methods of shaping the employment level in forest districts taking into account natural−forest conditions and economic tasks being implemented in these organizational units.

Opis:
The effect of organismic variable age on human cognitive performance was studied under the impact of vibration in different automobile driving environments, namely city streets, rural roads and highways. Reaction time was measured in milliseconds through a human response measurement system specifically designed for the purpose. Results of the study showed that age had a significant effect in city street and rural road conditions. It was also found that the level of equivalent acceleration of vibration and a difficulty index significantly affected cognitive performance in all driving conditions. The organismic variable age observed to have a significant effect on task performance implied that youngsters and older people are stressed differently in specific environments of driving so proper stress management strategies should be evolved for them in order to minimize the number of accidents.

Opis:
Globally, textile and clothing companies are seeking to increase the export rate by minimising the cost of production. The same goal still applies for Tunisian companies. Nonetheless, production cost is the most but not the only significant factor that increases the competitiveness of a product. Others are important in beating the challenge of global competition. Among these factors are deadlines, economic and social stability, proximity, competence of the workforce and quality. In this study, the SAW method was used to develop a method for the calculation of a salary bonus according to the following criteria: the quality index, performance, difficulty of work, discipline, and attendance. This method improved the skills and wages of the workforce, decreased the absenteeism rate and increased the productivity of the company. The results showed in dependence on the case studied that the quality index varied between-0.053 and 1, performance between 40.5 and 81, the ranking vector between 0.545 and 0.911, and the bonus rate between 0% and 15%. The study reduced the absenteeism rate from 13.25% to 8.3% for direct labour. The quality of production was improved by reducing the defect rate by 8.54% to 4.6%. The efficiency of the chain was also improved by 51% to 67.3%.
