The Quantitative Structure Activity Relationship (QSAR) method, based on the three-dimensional (3D) shapes of formal molecular bodies and computed molecular descriptors, was used to calculate the octanol-water partition coefficient (logKow) of benzene derivatives to indicate their toxicity. The aim of this study is to use electron density threshold values as descriptors in predicting toxicology of benzene derivatives. Through Density Domain Analysis (DDA), a shape fragment database of benzene derivatives was constructed. Electron density threshold values were generated from molecular isodensity counter surfaces (MIDCO) of benzene molecules that were calculated at the ab initio HF/6-31G* level. Multiple linear regression analyses were performed, and two successful QSAR models were obtained. The analysis of variance (ANOVA) ratio for regression (F) and the significance of F (Fs) values was also used to evaluate the predictive power of the established QSAR models. The results indicate that the electron density threshold value, “a”, gives a specific description of the 3D shape of electron density clouds. These models were further analyzed by three 3D shape features as one local and two global descriptors based on the electron density threshold “a” value. The global and local properties of benzene derivatives were found to exhibit similar toxicity behaviors.

Bu vaka çalışmasında butik bir otelin mutfak bölümünde çalışanların el ile kaldırma ve taşıma pozisyonları NIOSH (Ulusal Mesleki Sağlık ve Güvenlik Enstitüsü) ve Snook yöntemleri kullanılarak ergonomik analiz edilmiştir. Çay ocağında çalışan personelin tutacakları kötü durumda olan damacanları kaldırarak semaveri uygunsuz bir biçimde doldurduğu saptanmıştır. NIOSH yöntemi ile analizi yapılmış ve kaldırma indeksi hem başlangıç hem de varış pozisyonu için sırasıyla 3.7 ve 5.4 olarak hesaplanmıştır. Her iki pozisyon içinde kaldırma indeks değeri 3’den büyük olduğu için iş çok riskli olarak tespit edilmiştir. Çalışanın gün içinde işlemi tekrarlaması uzun vadede iş ile ilgili kas iskelet sistemi rahatsızlıklarına yol açabileceğinden kesinlikle iyileştirme gerektiren bir iş olarak tespit edilmiş ve iyileştirme önerileri sunulmuştur. Mutfakta bulaşık sepeti taşıma işi de Snook tabloları yöntemi ile analiz edilmiş, çalışanın bu yükü taşımasında herhangi bir risk bulunmamış olmasına rağmen iyileştirme olarak sepeti taşıması için el ile itilebilen tekerlekli bir taşıma aracı kullanması önerilmiştir.; In this case study, manual lifting and carrying positions of workers in the kitchen area of a boutique hotel were ergonomically analyzed by using NIOSH (National Occupational Safety and Health Institute) and Snook methods. It was determined that the staff working in the tea oven lifted the water filled containers in an improper manner. By using the NIOSH method, the lift index was calculated as 3.7 and 5.4 for both the initial and final positions, respectively. The work was identified as very risky because the lift index value in both positions was greater than 3. It has been identified as a job that needs improvement and a recommendation for improvement is offered because the employee's repetition during the day may lead to work-related musculoskeletal disorders in the long run. The work of transporting dishwashers in the kitchen was also analyzed by the Snook charts method and it was proposed to use a hand-carried wheeled vehicle to carry the basket as a remedy even though the employee had no risk of carrying this load.

Purpose - The aim of this study was to analyse the officially recorded data of Turkey on occupational accidents by covering various kinds of data between the years 2003 - 2015. By this study a view is aimed to be taken over Turkey’s behaviour on occupational health and safety. Methodology – In this study, the statistical yearbook of the Social Security Institution (SSI) of the Republic of Turkey has been used as a data source. These data are arranged yearly and the trend is evaluated. Findings- The number of occupational accidents had fluctuations as increases and decreases between the years 2003-2012. After the year 2012, the number of occupational and fatal accidents had increased more than twice. The occupational accidents have occurred at the highest rates in the most populated and industrialized two cities in Turkey. Economic activities having the highest percentage of occupational accidents has been determined and interpretated. Conclusion- Occupational accidents can be reduced by taking effective and preventive measures. There are some tasks that should be fulfilled in order to create a secure work place by employers and employees. Employers should apply occupational health and safety legislation and take preventative measures and train the employers regularly against work related accidents. Furthermore, employees should be conscious and careful about the accidents and fulfill their obligations regarding to work safety while working. Public institutions should work more on creating a secure work place and creating a culture of work safety.

Gül, Ayşenur
Son zamanlarda, nanoteknolojinin gündelik hayatımızda yer alması ile tekstil, kaplama, katalizör, tıp, elektronik, gıda, enerji gibi çeşitli sanayi ve teknoloji sektörlerinde önemli değişiklikler ve gelişmeler kaydedilmiştir. Nanoteknoloji, pek çok malzemenin yapısında son derece küçük ölçekte değişiklikler yapabilmeyi sağlayan bir bilim dalıdır. Ayrıca, mevcut malzemelerin belirli bir amaca yönelik olarak geliştirilebilmesi ve daha hafif, reaktif olmayan ve daha güçlü ve dayanıklı alternatifler üretmek de mümkündür. Araştırma laboratuvarlarının yanı sıra endüstriyel ve ticari alanlarda da nanoteknoloji uygulamaları artmaktadır. Nanomalzemeler ile çalışan işçiler ve işverenler bu maddelere solunum, cilt ile temas veya yutulma yoluyla maruz kalabilirler. Fakat, nanomalzemelerin çevre ve insan sağlığı üzerindeki riskleri ile ilgili henüz yeterli veri oluşmamıştır. Bunun yanında, bu malzemelerin bazıları, yüksek yüzey alanlarına, çok düşük ateşleme enerjilerine ve sıcaklıklara bağlı olarak iş yerinde patlama ve yangın çıkartabilir. Bu raporun amacı, nanomalzemelerin potansiyel sağlık etkisini ve iş yeri tehlikelerini tanımlamak ve bu materyallerin güvenlik kültürü ve kontrol yöntemlerini geliştirmektir.; Various industry and technology sectors such as cosmetic, textile, coating, catalyst, medicine, electronic, food, energy, and so on, have been improving and changing our lives radically by the help of nanotechnology. Nanotechnology is a discipline which makes it possible to tailor the structure of different materials at extremely small scales. Furthermore, existing materials can be improved based on a specific purpose and it is possible to produce lighter, non-reactive, and much stronger and durable alternatives. There is an increasing attention on nanotechnology applications from research laboratories to industrial and commercial settings. Workers and employers who work with these settings may be exposed to these materials through inhalation, skin contact, or ingestion. However, there is not enough available data regarding the risks of nanomaterials on environment and human health. Besides that, some of these materials may create explosions and fire due to their high surface area, and very low ignition energies and temperatures in the workplace. The goal of thisreport isto describe the potential health effect and workplace hazards of nanomaterials and develop safety culture of these materials and control methods.
