“…The DMU's ability to produce the maximum possible output by optimal use of the input combination it possesses is defined as pure technical efficiency and the ability to carry out production on the appropriate scale is defined as scale efficiency (SE). Finally, the overall efficiency score is gained by multiplying the scores for these two efficiencies as in Equation 1 below (Kasap, 2011):…”

This study analysed the efficiencies of Turkish apparel retailers in 2010 by using actual retail data based on the research conducted by PricewaterhouseCoopers and published in TurkishTime periodical by using data envelopment analysis method in Excel Solver. The efficiencies of the retailers were evaluated in terms of overall technical efficiency, pure technical efficiency and scale efficiency. In addition, input targets for each company were calculated in order to identify the improvement ratios that each of the inefficient companies can become efficient by achieving these ratios.

Developments of countries are interpreted through many parameters. One of the most important parameters according to the order of importance is perhaps the occupational accidents. Especially in recent years, work related (or occupational) accidents occurred at different sectors did not decrease; they even increased despite the developments in the technology and emphasis made on the regulations. This situation can be interpreted as an open debate in which the employees still do not internalize the work they do. Often, enterprises do not choose the right personnel for the job or the personnel chosen are not oriented to the work with the through proper methods. When the mining sector is taken into account, this problem becomes even clearer. Among the many reasons for this problem, it can firstly be mentioned about the difficulty of employing qualified and well-educated personnel. Since the enterprises do not have many options in the solution of this problem, their approach to work accidents should be institutionally a highest priority. During this process they must also use proactive approaches. For example, all accidents and occupational diseases should be recorded, possible causes of them should be put forth, and statistical analysis should be conducted to guide the future of the institution. In this study, the work accidents took place in both underground and surface facilities at Western Lignite Corporation (WLC) which is one of the most important lignite producers in Turkey between the years 2014 and 2018 were analyzed by Data Envelopment Analysis (DEA). The types of accidents were also examined and interpreted using the information obtained from the calculation of accident frequency, accident weight and accident probability rates. With the sensitivity analysis realized, it was tried to draw attention to the occupational safety measures to be made in the future.

“…Health symptoms of heat damage include but are not limited to fervescence, heatstroke, and nervous system disease [11][12][13]. The labor productivity of the workers decreases, while the accident rate increases [14,15]. To improve the thermal environment and ensure personnel life and health safety, mine cooling is necessary.…”

Heat damage in deep mines is severe and can lead to adverse health effects. The existing refrigeration schemes for the heading face in excavation roadways aim to cool the whole cooling region. However, the ratio of the area occupied by workers to that of the cooling region is quite small. A great quantity of energy for refrigeration is doomed to waste. In this study, a new cooling strategy for building a non-uniform environment in the heading face was developed. A certain quantity of well-designed tracking air coolers were distributed in the excavation roadway near the heading face. The air cooler tracked the constantly moving workers and blew cold air to them. Economic analysis based on estimation of the cooling load for this cooling strategy was conducted. The airflow in the excavation roadway was numerically simulated to estimate the cooling effect. An average energy saving of approximately 30% could be realized. The thermal environment for the workers whether near the heading face or in the roadway improved. This cooling strategy should be considered in all of mine cooling.
