Social responsibility projects have also taken an important place among current public relations activities in terms of contributing positively to the image of the institutions. Today, organizations carry out social responsibility projects on various issues, from economic development to public health, from education to sports. Undoubtedly, the nature and environment-oriented projects have become increasingly widespread in recent years. Afforestation activities are also included in this scope. The study aims to provide information about social responsibility projects on afforestation studies and evaluate the content of these studies. In this context, the “81 Forests in 81 Cities” project realized by Türkiye İş Bankası was chosen as the sample case. This project was selected because it is the most comprehensive one in Turkey, covering a large area and long duration. In the study, the structured interview technique was used as the essential data collection method, and questions on the aims and process of the project and the results achieved were taken place. The data were evaluated qualitatively. In the light of the findings, the necessity of carrying out activities on raising awareness of the target audience, using appropriate planting techniques, and maintaining replacement planting and stand tending activities have emerged in such studies. It is clear that social responsibility projects that can be carried out in both afforestation and other areas of forestry will have a positive reflection on the enterprises that carry out and support the project, as well as make significant contributions to the society in terms of environmental, social, economic and cultural aspects. At this point, it is vital to support the creation of ideas for social responsibility projects related to nature and forestry and to develop incentives.","PeriodicalId":32505,"journal":{"name":"Ormancilik Arastirma Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67632508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is one of the plants preferred in Landscape Architecture planting designs with its form, aromatic leaves, abundantly blooming pinkish-white flowers and fruit beauty. It is very effective in groups or solitary use. It is resistant to urban climate and cold. In this study, our aim is to encourage the use of this plant, which is valuable with its aesthetic properties, by propagation with cutting production in the urban landscape. Within the scope of the study, the production technique with mild cutting, which is one of the vegetative production techniques, was used. In this current study, the effect of different hormone applications on the rooting success of softwood cuttings of Magnolia kobus was investigated. 0 (control), 3000, 5000 and 8000 ppm doses of hormones IBA (Indol-3-butyric acid), IAA (Indole-3-acetic acid) and NAA (Naphthalene acetic acid) were applied to the cuttings. Cuttings were planted in perlite medium under greenhouse conditions (20±2 ºC air temperature, 25±2 ºC rooting table lower temperature, 70±2% humidity). After about 4 months, the cuttings were removed and the rooting rate (%) and root lengths (cm) were determined. As a result of the study, the highest rooting percentage (60%) was seen in cuttings treated with 8000 ppm dose of IBA hormone. The highest root length values in cuttings were determined in cuttings treated with IAA 3000 ppm and 5000 ppm doses. According to the results of analysis of variance, it was determined that hormone applications had a significant effect on rooting (P: 0.000 ˂ 0.05). This study was supported by Karadeniz Technical University Scientific Research Projects Unit (Project no: 9733).","PeriodicalId":32505,"journal":{"name":"Ormancilik Arastirma Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67632215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For wood material surface treatments, many methods have been developed in the field of application, as well as using a large number of surface treatment materials. It is very important to determine the interaction between wood and surface treatment agents, to improve wood properties and to determine their suitability for different usage areas. For this purpose, 3 different tree species; Leafy tree species Eastern Beech (Fagus Orientalis Lipsky.) and Bearded Alder (Alnus glutinosa subsp. Barbata (C.A. Mey.) Yalt.) and coniferous Eastern Spruce (Picea Orientalis L. (Link.)) and cellulosic varnish from varnish species , polyurethane varnish was used. Trial samples were prepared in the specified dimensions and examinations were made about the gloss on the samples. When the gloss values parallel to the fibers and perpendicular to the fibers are examined for cellulosic varnish, Beech wood has the lowest gloss value, while the highest gloss is determined in Alder wood. For polyurethane varnish, no difference was found when wood species were considered on gloss in both perpendicular and parallel directions to the fibers. As a process type, 90 seconds microwave showed a negative effect for polyurethane varnish. It was determined that 90 seconds of microwave application decreased the brightness values in tree species. As a result; It was determined that microwave application affects the gloss properties of varnishes.","PeriodicalId":32505,"journal":{"name":"Ormancilik Arastirma Dergisi","volume":"5 12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67632558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, meeting the increasing need for forest products without endangering the ecosystem will be the most important issue to be considered. In this respect, increasing the use of wood materials obtained from forests is among the subjects of interest of researchers. With this study, it is aimed to increase the useful life of the alder tree, which has a wide distribution area in our country, and to bring it to industrial areas. Alder (Alnus glutinosa) is abundant in the Black Sea region, but has no industrial value. Impregnated camellias obtained from Scots pine (Pinus sylvestris L.) wood, which is frequently used in industry, were used as reference product. Camellias prepared from alder and yellow pine impregnated with Tanalith E and Celcure AC 500 were exposed to the external environment. The biological strength of the samples (Coniophora puteana and Poria placenta) and washing mechanism were investigated. The rot test was carried out according to the EN 113 standard, the washing test was carried out according to the AWPA E11 standard. Washed water samples were subjected to copper analysis with ICP-MS device. According to the results obtained, the weight loss of the impregnated wood material in the rot test was much lower than the control groups. The lowest washing and copper rates were obtained from Scotch pine wood.","PeriodicalId":32505,"journal":{"name":"Ormancilik Arastirma Dergisi","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67632273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For each sampling area, woody plant taxa and habitat characteristics were recorded in the inventory book. Multiple permutation test (MRPP) was applied in order to determine the most suitable of the groups obtained from the cut-off levels by cluster analysis. Indicator plant analysis was applied in order to determine the indicator plant species of the most effective vegetation group separation by the multiple permutation test. Pearson correlation analysis was applied to reveal the relationships between alpha diversity index values and environmental factors. Pinus nigra, Rosa canina, Populus nigra subsp. caudina and Malus sylvestris subsp. sylvestris were determined to be the most common species in the study area. In the study, the most appropriate vegetation classification was obtained in 3 groups. As a result of the mentioned statistical analyzes, it was determined that aspect differences are important in the formation of the most suitable vegetation group separations. The result obtained was supported by the determination that the species diversity in the region is higher in southern aspects compared to northern aspects.","PeriodicalId":32505,"journal":{"name":"Ormancilik Arastirma Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67632440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal, mechanical and optical properties of the test papers produced within the scope of the study were measured and optimized. In the study, as a result of the thermogravimetric (TGA) analyzes of the test samples, it was determined that the carbonization and residue amount increased significantly with the increased Firetex ratio. It was determined that the limit oxygen index (LOI) values of the samples also increased with the increasing Firetex ratio, the LOI value of 26 accepted as the standard with 50% concentration was exceeded, and the device limits were exceeded in the samples treated with 100% fire retardant. In the study, the strength properties of the test papers were also measured. It has been determined that the increased Firetex ratio improves the resistance against burning, while reducing the tensile and tearing resistance. The best strength values were obtained with the solution containing 25% Firetex, but the strength values of the samples treated with the solution containing 50% Firetex were also close to the control levels. The resistance values of the samples treated with 75% and 100% Firetex were measured far below the standards. In addition, although it is not very effective in terms of newsprint, it was determined that the increased Firetex ratio also increased the yellowness of the papers.
