The paper deals with the identification of occupational injury among workers in selected cement industries of Bangladesh. In this regard, the case study was conducted to extract the overall scenario of the occupational injury. Injury data were collected by using questionnaires from the workers as well as supervisors of four cement industries. The data collected were analyzed in terms of different variables, such as body parts, agent of accident, experience, age, skill, and type of injury. Pareto analysis was then applied to find a pattern of occupational injury among the workers. The study disclosed that arm, leg, hand finger, Eye and head covered 82.81% of total i njury frequency, 76.56% of total injuries by welding, bucket elevator, belt conveyor and weight lifting, low experienced and high experienced workers have 84.38% of total injury frequency, age group of 21-25 and 51-55 have the maximum injury frequency, 78.13% injury occurred by highly skilled and unskilled workers and 79.1% of total injury is temporary disable type injury. The paper also provides specific suggestions followed by some action plans. Keywords injury; accident; workers; safety; cement industry; training.

Abstract In the paper, there has been discussed the problem of measurement and assessment of effectiveness of auxiliary processes [Kaplan: 2001, Porter: 1985] of production in the enterprise of the cement industry operating in international markets. The applied research method is literature studies and the case study, which will allow for the accomplishment of the objective of the paper which is the parameterization and assessment of costs of ancillary activities of production in the area of maintenance. The paper is important and up-to-date since auxiliary processes of production generate high costs, therefore, they should be within the area of interest of managerial staff of these companies.

Stack Emissions

Co-incineration of wastes started more than 20 years ago. In the last 10 years, the use of alternative fuels in the cement industry is continuously increasing. The use of solid wastes in cement kilns is one of the best technologies for a complete and safe destruction of these wastes, due to the fact that there is a simultaneous benefit of destroying wastes and getting the energy. However, particulate matters (PM) and gaseous chemicals emitted from a source into the environment could be directly transmitted to humans through air inhalation. Therefore, for accurate health risk estimation, the emission of pollutants must be determined. In this work, the analysis of the emission of different pollutants when replacing partially the fuel type used in a cement kiln is done. PM, PM10, heavy metals and inorganic pollutants are analyzed. The methods used for sampling and analysis are the standard methods suggested by the EU regulations for stack analysis. Experimental results have shown the encouraging results: in particular clinker characteristics were unmodified, and stack emissions (NOx, SO2 and CO mainly) were in the case of tires, slightly incremented but remaining almost always below the law imposed limits, and in some cases were even decreased.

Decision Making Units

This paper introduces a new robust data envelopment analysis (RDEA) approach for analyzing and ranking the organizations' operations strategies. In the proposed RDEA method, pessimistic and optimistic efficiencies of decision making units (DMUs) obtained from the robust counterpart of the envelopment form and the optimistic counterpart of the multiplier form of DEA are introduced. The inputs and outputs data are assumed to be bounded data (interval numbers) in the proposed models. A case study in the cement industry is presented to demonstrate the applicability of the proposed RDEA approach. The results obtained from the authors' proposed RDEA approach is more robust and their method provides a more complete ranking of the DMUs compared to conventional Likert-based DEA model.
