Top, Yener; Adanur, Hakan; Öz, Mehmet
Risk factors in the workplace vary according to the sector and scale of the business. Small and medium-sized enterprises, especially those within the scope of the wood-products manufacturing industry, are considered to be risky, and have a relatively high accident rate. Here, we focus on the timber and furniture industries, two subsectors of the wood-products industry. A total of 47 enterprises was visited and asked to participate in a formal structured questionnaire. The findings show that the usage of personal protective equipment (PPE) was low, that lighting was often inadequate, and that these enterprises typically lacked routine organising and cleaning practices. The subsectors and the occupational health and safety practices were found to be independent, and a statistically significant relationship could only be established between the subsectors in terms of the use of dust masks and goggles. Despite the unfavourable working conditions, only one business out of 47 reported having an employee with symptoms of occupational diseases.

Dioryctria sylvestrella Ratz. poses a remarkable hazard for the Pinus brutia Ten. in Turkey. In the current study, the larvae gallery resin of five trees and essential oils of resin, which was obtained with the AcidPaste Method, were analyzed using the Gas Chromatography and Mass Spectrometry (GC-MS) Method. Thirty nine compounds were found in larvae gallery resin, which were produced by Dioryctria sylvestrella Ratz, while thirty six compounds were extracted from oleoresin obtained by the Acid-Paste Method. The most common compounds of larvae gallery resin were α-pinene at a rate of 20.2%, β-caryophyllen at a rate of 10.8%, γ-terpinene at a rate of 10.1% and β-pinene at a rate of 9.4 percent. The most common compounds of oleoresin were α-pinene at a rate of 19.7%, β-pinene at a rate of 13.3%, γ-terpinene at a rate of 10.2% and β-caryophyllen at a rate of 7.8 percent. Also, the quantities of some compounds within larvae gallery resin such as β-pinene, limonene, and sylvestrene decreased compared to those of oleoresin, while the quantities of some compounds in oleoresin including α-longipinene, α-terpineol, and longifolene increased compared to that of larvae gallery resin. However, no qualitative difference was found.

Top, Yener; Adanur, Hakan; Öz, Mehmet; Yasar, Mehmet
In total, 95% of all business enterprises established in Turkey are micro-scale, and this figure increases to 98.6% in the forest products industry. Micro-scale enterprises are important in terms of production, employment, and overcoming economic imbalances among regions. The forest products industry, which includes three subdivisions within the manufacturing sector, occupies an important place in the overall Turkish manufacturing sector. Thus, this study examined the structural characteristics of forest product enterprises in Gumushane Province. The research involved in-person interviews with personnel at 47 enterprises. The data revealed that the sawmill division was especially important with respect to the use of local poplar logs. The sawmill and furniture divisions accounted for 28% of all enterprises and 26% of all employees in the manufacturing sector in Gumushane. We found that 57% of enterprises had difficulty in finding working capital and 55% of enterprises experienced shortages of labour. The average contribution of each forest products business to employment (2.55) was more than that of other manufacturers in Gumushane (2.27). The forest product businesses in Gumushane resemble other micro-scale enterprises located in other regions of Turkey in terms of their structural properties.

Okan, Onur Tolga; Varlibas, Hulya; Öz, Mehmet; Deniz, Ilhan
Eastern Black Sea region has wide genetically plant diversity due to physical and different climatic characteristic. These plants, which are potential source of antioxidants, prevent the oxidative stres caused by oxygen and photons at the same time. Interest of antioxidant compound has been increased for last years. The reason of this, it is believed that an increased intake of food, which is rich in natural antioxidant, is associated with a lower risk of degenerative diseases. In this study, 10 plants, which are sources of antioxidant and marketable in Eastern Black Sea region, were chosen. Antioxidant activity and potentials use area of these plants were examined. Moreover, antioxidant compounds and determination of antioxidant activity methods were discussed.
