The primarily goal of plot-less sampling methods is to reduce costs and rapid survey of plant communities. First full inventory was conducted in two 30-ha sites of Saxaul populations geo-morphologically different. In first site (site I), population had random pattern while in second site (site II) clumped pattern was observed. Crown diameters and spatial situation of all trees were recorded using distance and azimuth. Data were transferred to computer and stem map was generated with ArcGIS Software. Distance sampling methods include point-centred quarter method (PCQ), joint-point method (JP), Random pairs method (RP), T-Square method (T-Sq) and Quartered neighbour methods beside fixed area plot (FAP), n-tree and variable area transect (VAT) methods were conducted on generated stem maps. A time study was done aiding indices determined in field works. In site I, point centred quarter estimator with measurements to the second closest individual in each quadrant had the lowest relative bias (RBIAS) in estimating density followed by 3-tree and closest individual methods. In clumped pattern (site II), variable area transect method with measurements to the 4th and 5th closest individuals in each transect brought the best results. The most time consuming methods after fixed area plot, were point centred quarter estimators while methods considering measurement to the closest individual were rapid. Considering RBIAS and Time together, VAT method was the best sampling method in clumped pattern followed by point centred quarter estimator with measurements to the second closest individual in each quadrant and closest individual estimators. In random pattern, point centred quarter estimator with measurements to the second closest individual in each quadrant was the best method followed by 3-treeandclosest individualestimators. But for estimating cover per unit area N-tree methods performed well. As in this site, VAT method located in 4th grade, and due to simplicity of field works related to this method, in the case that the investigator would not be able to clearly define spatial pattern of the population, this method can be recommended as well.

When reviewing the work demand factor on human it is necessary to consider the analyses of requirements on locomotive organs, mental processes and also requirements on human sensual functions. The document points out possibilities of usage selected methods of work activity studies in particular conditions. It shows that by realizing precautions, which are a result of the workload analysis it is possible to achieve workload decrease and also work productivity increase.

Ocena ryzyka zawodowego w świetle przepisów obowiązującego prawa jest podstawowym narzędziem, które powinien wykorzystywać pracodawca w celu zapewnienia bezpieczeństwa i ochrony zdrowia pracowników. Nauczyciele akademiccy to grupa pracowników, których praca ma specyficzny charakter. W ramach artykułu dokonano identyfikacji zagrożeń oraz oceny ryzyka zawodowego na stanowisku nauczyciela akademickiego, będącego pracownikiem uczelni państwowej. W artykule przedstawiono podstawowe pojęcia z zakresu problematyki ryzyka zawodowego, opisano stanowisko pracy i czynności wykonywane na stanowisku pracy nauczyciela akademickiego. W artykule zawarto chronometraż oraz zidentyfikowano uciążliwości na badanym stanowisku pracy za pomocą wywiadu. Do oszacowania ryzyka zawodowego wybrano metodę risk score. Praca zawiera dokładny opis metody oraz przedstawione w formie tabeli ryzyko zawodowe na stanowisku pracy nauczyciela akademickiego. Zaproponowano rozwiązania, których celem jest zmniejszenie ryzyka oraz sporządzono szacunkowy kosztorys proponowanych zmian. Oceniono możliwość wprowadzenia owych propozycji pod względem finansowym.

The assessment of occupational risk in the light of applicable law is a basic tool that should be used by the employer to ensure the safety and health of workers. Academic teachers are a group of employees whose work is of a specific character. The article identi-fies hazards and includes an occupational risk assessment for an academic teacher who is an employee of a state university. This paper presents the basic concepts in the field of occupational risk, a description of the workplace and the activities performed at the teacher's workplace. The article includes a time study and identified burdensome conditions at the studied workstation by conducting an interview. The Risk Score method was selected for the risk assessment. The work contains a detailed description of the method and a table presenting the occupational risk in the workplace of an academic teacher. Solutions designed to mitigate risks and a cost estimate of the suggested changes are proposed. The possibility of introducing these proposals was assessed financially.
