The study aimed to evaluate the current status and potential risks of pesticide use of 23 chili growing households in the Thanh Binh district, Dong Thap province, Vietnam. The result shows that farmers used a total of 40 commercial pesticide names with 43 active ingredients, of which two active ingredients, i.e. Benomyl and Fipronil, were banned. The frequency of pesticide spraying for chili protection averaged at 8.93 times/crop, for weed control at 1.83 times/crop, for pests at 12.43 times/crop, for disease control at 14.48 times/crop and for chili growth promoting at 4.82 times/crop. Farmers sprayed pesticides with higher doses than recommended on the labels when pests and diseases occurred on chili farm. The active ingredients in powder and liquid pesticides of Mancozeb, Metalaxyl, Propined, Difenoconazole, Abamectin and Azoxystrobin have been frequently used with estimated concentrations of 5023±3886.36, 337.71±237.50, 4093.92±3628.57, 289.27±264.73, 31.60±29.02 and 652.57±468.35 g/L/ha, respectively. The predicted amounts of ineffective use of such pesticides as Benomyl, Cypermethrin, Fosetylaluminium, Propiconazole, Tebuconazole, Buprofezin, Chlorfenapyr and Difenoconazole, could pose great risks to the environment and humans. Burning is the main method chosen by chili farmers in the treatment of pesticide packaging after use. The study suggests local environmental managers should train farmers in the use and management of pesticide wastes more appropriately.

The paper shows that phenomena requiring an active attitude of managers, including among other things: creating risk management policy, risk identification, risk measurement, taking actions and control, are the subject of risk management. The tasks of a risk manager in the enterprise refer to a professional interpretation of economic correlations, occurring both outside and inside the enterprise. They consist in assessing information about potential risk, possible ways of lowering its effects, unfavourable for the enterprise, and indicating the advantages coming from taking risky actions. The article contains results of own research among 156 Polish building companies in the area of risk factors of building investment projects. According to opinions of Polish building entrepreneurs, Polish enterprise have biggest problems with the scope, schedule, budget and quality requirements of construction projects.

Praca ukazuje, że zjawiska wymagające aktywnej postawy menedżerów, w tym dotyczące m.in. budowy polityki ryzyka, jego identyfikacji, pomiaru, podejmowania działań, kontroli, są przedmiotem zarządzania ryzykiem. Wskazano, że zadania menedżera ryzyka w przedsiębiorstwie sprowadzają się do fachowej interpretacji zależności gospodarczych, pojawiających się zarówno w otoczeniu, jak i wewnątrz przedsiębiorstwa. Polegają one na ocenie informacji o potencjalnym ryzyku, możliwych sposobach zmniejszenia jego skutków niekorzystnych dla przedsiębiorstwa oraz wskazaniu korzyści płynących z podejmowania działań ryzykownych. W artykule przedstawiono wyniki badań własnych przeprowadzonych w 156 polskich przedsiębiorstwach budowlanych w zakresie czynników ryzyka budowlanych projektów inwestycyjnych. Ukazują one, że przedsiębiorstwa budowlane borykają się głównie z problemami zakresu, harmonogramowania, budżetu i wymagań jakości projektów inwestycyjno-budowlanych.

The present paper attempts to evolve a new model by considering various indicators of different types of land degradation or desertification, namely, water erosion, soil salinity, vegetation degradation, and lowering of ground water table for finding areas with higher rate of degradation. The Runiz basin, located in the southern Iran, has been selected as a study area to assess the hazard of desertification. The thresholds for the severity classes of indicators were established and then the hazard map for each indicator of types of desertification has been prepared in a GIS. The risk classes of different risk maps were calculated on the basis of classification of risk scores derived by cumulative effect of all the attributes of indicators after overlying them in the GIS. It was possible to distinguish the areas under ‘actual risk’ from areas under ‘potential risk’ of desertification types. Also areas under potential risk were classified to subclasses with different probability level to show a statistical picture of risk in future. The final map of risk of desertification was produced by overlaying all four maps of degradation types. Results show that potential risk areas and areas under actual risk are almost equal, indicating further threat of desertification in future in the half of the region. Also severe condition in the half of region shows environmentally bad situation in the study area. It is hoped that this attempt using GIS will be found applicable for other regions of the world.

Project implementation and its risk considering, as well as an appropriate response to risk is the part of any complex activity. Project management of implementation of e-learning in terms of education requires a methodical approach. It includes the definition of e-learning basic concepts, evidence of its effectiveness, development of faculty requirements for implementation, as well as possible risks during implementation. Blended e-learning is preferred form in terms of conditions of Faculty of Business Economics. It is a modern form of individual students training which properly combine the attendance form to e-learning form of study.
