Electric power generation from renewable energy sources such as solar energy, wind energy and geothermal energy is an alternative option to energy generation from fosil flues. Renewable energy sources are more advantageous when we consider the environmental damage caused by fossil flues during energy generation. Our country is rich in terms of renewable energy resources with its location. When we consider the daily sunshine duration and the wind force in the flat plains, the number of power plants that generate electrical energy without harming the environment with solar panels and wind turbines is increasing day by day. In this study , as a result of field observations of a power plant that converts solar energy into electrical energy with solar panels in Çorum by instructors who have class B OHS certificate and field experince, the risk score was calculated by determining the hazards and risks by 5x5 L-type Matrix Risk analysis which is a qualitative risk assessment. According to the calculated risk score, twenty-four risks which include four high level risks, fifteen medium-level risks, and five low-level risks were identified and recommendations were made. We think that this study will make a positive contribution to the power plants to be established and to the actively onoing plants in terms of occupational health and safety.

Kalkon ve isoindol türevleri önemli biyolojik aktivitelere sahip bileşiklerdir. Bu iki birimi aynı yapıda taşıyan hibrit moleküllerinde biyolojik aktivite gösterdikleri bilinmektedir. Ayrıca β-merkaptanlar bazı biyoaktif bileşiklerin sentezi için başlangıç materyali olarak kullanılmaktadırlar. Bu çalışmada, isoindolsübstitüe-kalkon türevlerine (3a-j) moleküler iyot katalizörlüğünde tiyofenol katılarak yeni β-merkapto karbonil bileşikleri, ((3aR,4S,7R,7aS)-2-(4-(3-(feniltiyo)-3-(aril)propanol)fenil)-3a,4,7,7a-tetrahidro-1H-4,7-metanisoindol-1,3(2H)dion) (5a-j) yüksek verimler ile elde edildi. Elde edilen yeni bileşiklerin yapıları 1 H-NMR, 13 C-NMR, FT-IR ve Elementel Analiz spektroskopik yöntemleri kullanılarak aydınlatıldı.

T he human labor force gained importance with the industrial revolution. At first, there was barely any study on occupational accidents and diseases. As the time went on, the term "occupational health and safety" gained importance primarily in England and later on in other European countries with "providing the workers a healthy and safe environment" in mind as occupational health issues rose and accidents began happening due to the nature of the work. In time, the Occupational Health and Safety legislation (numbered 6331) has been implemented so as to prevent occupational accidents and diseases [1].
