This study was handled to analyze the forestry workload according to seasons and business types and to find out the problems while carrying out forestry activities and to develop solution suggestions in the Kulakkaya and Kemerköprü Forest Management Chieftaincies of the Giresun Regional Directorate of Forestry in Turkey. The data obtained from records of the Kulakkaya and Kemerköprü Forest Management Chieftaincies, and also by systematic observation, interviews and experiences in these chieftaincies, were used. According to the data, the seasonal and yearly works of the forest management chieftaincies were carried out in in 2016 were investigated by dividing work categories such as personnel, business-production-marketing, silviculture-afforestation, public relations, forest protection, cadastre-ownership etc.). The types of work in each season, and their intensity were evaluated according to the periods on the basis of the chieftaincies and the differences were revealed. In addition, the factors affecting the work load and the main problems in the forest chieftaincies were determined. According to the results of the research, forestry activities, their densities and periods, main problems, and the factors affecting workload in the Kulakkaya and Kemerköprü Forest Management Chieftaincies are similar. It was determined that works related to forest management, combating forest fires, construction and forest rest areas were the highest in the summer months, silviculture and afforestation works were the highest in the spring, works of forest roads were the highest in the summer and spring, works related to compulsory wood needs and non-wood forest products were the highest level in the autumn, whereas the works related to fighting against forest pests, cadastral-ownership, production, transportation, storage, personnel, marketing, fighting against forest crime, research, planning, office works, correspondence and public relations continued intensely in all seasons. According to the results, some proposals were developed to reduce the workload of the forest management chiefs and to solve the problems, and thus to work more efficiently and successfully.

The main aim of the study is to determine leisure time and recreational trends of vocational college students, levels of participation in existing recreational activities and recreational needs. Bülent Ecevit University Çaycuma Campus has implemented a total of 400 student questionnaires registered in 11 associate degree programs in spring semester 2017-2018. The students were selected by chance sampling method. In the evaluation of the questionnaires frequency, percentage and Anova tests were done through SPSS 22.0 program. According to the survey results, most of the students find that their existing recreation areas are inadequate. Students prefer physical activities as recreational activities and enjoy indoor or outdoor recreational activities. It provides the basic needs of students with limited opportunities and therefore has limited participation in some recreational activities that require excessive fees. Students prefer to shop as shopping malls and leisure time activities as a recreational activity in Çaycuma. As a result, suggestions have been developed in the context of being able to pass the leisure time of Çaycuma Yeleşkesi students better.

In this study, usage possibility of particles obtained from kermes oak (Quercus coccifera L.) wood in board production was investigated. Boards were produced from mixtures of kermes oak and brutian pine (Pinus brutia Ten.) particles. The ratios of kermes oak:brutian pine were 0:100, 25:75, 50:50, 75:25 and 100:0 in the experimental design of particleboards. Chemical and thermal properties of particles used were determined and their effects on the physical and mechanical properties of the produced boards were revealed. Kermes oak particles exhibited higher α-cellulose and hemicellulose contents, but lower extractive and lignin contents than the brutian pine particles. Main chemical component analysis was supported by FTIR analysis. It was observed that kermes oak particles were more acidic than brutian pine particles. Monosaccharides were rhamnose (0.34%), arabinose (0.84%), xylose (21.24%), mannose (2.04%), galactose (1.01%) and glucose (50.44%) in the kermes oak particles and arabinose (1.72%), xylose (7.89%), mannose (10.65%), galactose (2.11%) and glucose (46.50%) in the brutian pine particles. Kermes oak particles presented higher thermal stability compared to brutian pine particles. Water absorption and thickness swelling values of produced particleboards failed to meet the requirements of the TS-EN 312 standard. Modulus of elasticity, modulus of rupture and internal bond strength values of the boards produced with 25 and 50% kermes oak particles met the requirements for general-purpose particleboards used in dry conditions according to the TS-EN 312 standard.

Turkish furniture industry is one of the rare sectors with an exportation higher than importation. In the sector with an annual export figure reaching 2.2 billion dollars, a reduction has been recently observed in EU market share. Leading the field in global markets can be achieved through the implementation of occupational safety administration policy in desired quality and standards. Occupational health and safety regulations contribute to enhancing the product lifecycle and the quality of working conditions as well as protection of employees against work accidents and occupational disease. In this study, it is aimed to determine the occupational health and safety awareness of workers in furniture production sector and the effects of demographic factors and intra business agents on the opinions concerning this issue. Within this framework, a face to face questionnaire implementation was conducted to a total of 84 employees in 35 workplaces situated in Erzincan province. At the end of the survey, the ratio of exposure to work accidents in furniture manufacturing enterprises was determined to be 61% and 50% of those workers have experienced work accidents at least two times. On the other hand, it was understood that employees’ ages, educational background, work department, the term of employment, the frequency of job change, and the maintenance interval of machine-equipment variables cause statistically significant (p<0.05) difference of opinion between employees. Besides, the inadequacy of safety gear, insecure behaviors, incompetency of occupational health and safety training, personal reasons and work overload were identified to be the most important causes of work accidents by employees

Tourism trends of tourists have changed in recent years. People have get away from crowded and customary tourism centers. Ecotourism, one of the alternative tourism types, is increasingly preferenced. In ecotourism, protection of environment and culture, social welfare and satisfaction of the tourists are important points. Ecovillages in ecotourism are ecological, economic and socio-cultural sustainable settlement models. In the regions where tourism has developed, the local people who have gone through agriculture have been trying to establish agriculture-tourism integration. One of the issues that contribute to this integration is organic agriculture. Because people who prefer ecotourism usually care to eat healthy. In this study, urban people's thoughts about organic products, tourism holiday purposes and production and consumption of organic products were evaluated in city center of Antalya. It has been determined that the people of Antalya want to consume mostly organic vegetables and fruits (87.00%), especially women participants have more trust in organic products. Participants who indicate that they will be partially vacationing in ecovillages and they will not be vacationing stated that they would like to organic product stands at the holiday resort.

In the forests of Turkey, there are more than 50 tree species whose spread depends on the climate and the topographic conditions. By 2015, the total forest area in Turkey was 22,342,935 hectares. Approximately 15 million hectares of this area consists of Quercus spp, Pinus brutia Ten. and Pinus nigra Arnold. Natural and human effects lead to changes in the structure and canopy cover of forests. Today, 29% of the forests in Turkey have (> 70% closure) canopy cover, 14% have (41 to 70% closure) canopy cover and 13% have (11 to 40% closure) canopy cover, all featuring a normal structure. The remaining 44% have a degraded (lower than 11% closure) structure. This study presents the current carbon stock in Turkey. In addition, a projection analysis has been conducted based on the hypothesis of improving 50% of those forest areas with canopy cover lower than 11% by incrementally rehabilitation. Because of these rehabilitation studies, it has been determined that tree wealth, volume increment and carbon stocks would increase in the forest. Based on this hypothetical rehabilitation modeling, the suggested improvements to the structure of the forests would contribute to prospective forest assets and carbon sequestration estimations.
