Okcu, Melih; Topaloglu, Fatma Nil
Sainfoin (Onobrychis viciifolia) subjected to a range of studies relating to agronomy, environmental preferences, crop protection and plant-microbial interactions, is an important forage species in agriculture, that be prefered by farmers than other forage legumes. This fact has give importance to breeding of this plant for the development of diverse varieties and so for this purpose many wild forms are cultivated. The most important problem in sainfoin cultivation is poor germination problem in wild species. With the aim of solving this problem, we carried out to evaluate the response of wild sainfoin seeds to the application of different gibberellic acid (GA3) (a germination hormone) concentration in vitro conditions. Five levels of gibberellic acid (100, 250, 500, 1000 and 1500 ppm) was used in the test. Seed coat was removed and the seeds were placed on Murashige&Skoog (MS) medium supplemented with gibberellic acid (GA3) and kept under these conditions for 46 days. Seed germination percentage and germination associate parameters; speed of germination, mean germination time, mean daily germination, peak value and germination value, were calculated. The experiment was carried out using complete block design with three replications. According to the results obtained from different GA3 application medium, the highest germination percentage 48,89 recorded at in medium containing 250 ppm GA3 whereas in control has recorded 42,22 at the end of the 46th day. Other concentrations, 100, 500,1000 and 1500 ppm, achieved a reduction in seed germination compared to control, respectively 28,15, 15,56, 24,44, 34,81. Not only in germination percentage result, but also in other germination associate parameters, the addition of 250 ppm gibberellic acid to Murashige and Skoog medium increased the values compared to the control and ensured a rapid increase and peak between the 8th and 12th days in all parameters.

Sahin Macit, Nazife
This study analytically assesses the climate change and environmental sustainability performance of G20 countries using data from the 2024 Climate Change Performance Index (CCPI) and Environmental Performance Index (EPI) reports. The analysis employs Sum-Weighted Information (SWI) and Ranking Alternatives with Weights of Criterion (RAWEC), which are Logarithmic Decomposition of Criteria Importance (LODECI)-based multi-criteria decision-making (MCDM) methods. The study created three separate decision matrices, taking into account the CCPI and EPI criteria individually, as well as their combination. The criterion weights were determined using the LODECI method; greenhouse gas emissions, climate policy, and air quality were the most significant criteria. The results show that China and Saudi Arabia demonstrate strong environmental performance in CCPI-based rankings, while Germany, the United Kingdom and France demonstrate strong performance in EPIbased evaluations. In the integrated analysis, Germany ranked first using both methods. The consistency of the rankings obtained using the SWI and RAWEC methods was high, which supports the reliability of the analyses. However, some differences in ranking were observed depending on the method used, the distribution of criteria and the country sample. Overall, the study emphasizes the pivotal role of methodological diversity and data-driven approaches in multidimensional environmental assessments for policy-making, while demonstrating the robustness of the findings through sensitivity and comparative analyses.

Berktas, Serap
This study aimed to investigate the effects of dietary fibers obtained from cold-pressing by-products on the bioactivity of Spirulina (SP) during in vitro digestion. For this purpose, insoluble dietary fibers (CCDL and KCDL) were extracted from cold-pressing by-products of flaxseed and black cumin. SP was combined with CCDL and KCDL, and subjected to an in vitro digestion protocol (INFOGEST). The results showed that the total phenolic content of SP decreased after oral and gastric digestion with the addition of dietary fiber. After small intestinal digestion, the total phenolic content increased. Antioxidant activity values (DPPH and ABTS) decreased in the presence of dietary fiber, while chlorophyll values increased after small intestinal digestion. In particular, in the presence of CCDL, the chlorophyll content increased from 1.61 mg g(-1) to 4.48 mg 2 g(-1) after small intestinal digestion. Furthermore, the bioactivity values of SP after in vitro digestion varied depending on the type of dietary fiber. While KCDL was effective in increasing phenolic compound content, CCDL was more effective in increasing chlorophyll content. Considering the bioactivity values of SP after oral, gastric, and small intestinal digestion, it was determined that the values increased especially in the small intestine. This highlights the possibility that the bioaccessibility and therefore the bioavailability, of SP can be increased through the incorporation of dietary fiber. The addition of bioactive compounds to the development of functional foods rich in dietary fiber has advantages for the food industry in terms of designing and improving healthy foods. This study emphasizes that the in vitro digestion of Spirulina is regulated in the presence of CCDL and KCDL, and that the addition of dietary fibers may contribute to the potential health benefits of Spirulina.

Dogru, Bulent
In this paper we investigate the relationship between economic growth andunemployment in Eurozone through the implementation of Okun's Law using annual panel dataset covering the time period 2000-2012. Panel error correction and panel co-integration methods are used to test the linkage between unemployment and growth rate. We also investigate unemployment hysteresis using several non-stationary panel unit root techniques for unemployment hysteresis in all Euroregions. Findings suggest that Okun's Law is valid but coefficients are less thanOkun's coefficient for USA and other empirical studies on developed countries. Also we find that the relationship between economic growth rate and unemployment rate vary between countries.

Çavdar, Ozlem; Çavdar, Ahmet; Bayraktar, Ender
In earthquake engineering, the performance-based design method is used to determine the expected performance level of structures under an earthquake effect. The level of performance is related to the damage situation that could occur in the structure after the earthquake. In performance-based structural design, it is predicted that more than one damage level can emerge under one earthquake effect. In this study, the seismic behavior of a reinforced-concrete shear-wall building that collapsed during the 2003 Bingol earthquake was investigated by nonlinear static analysis and nonlinear dynamic analysis. The selected reinforced-concrete shear-wall structure is located in Bingol, Turkey. Local code was considered for assessing a seismic performance evaluation of the selected reinforced-concrete shear-wall building. The performance goals of the reinforced-concrete shear-wall structure were evaluated by applying the pushover (incremental equivalent earthquake load) method and procedures of the code and nonlinear dynamic analysis. According to the code, the reinforced-concrete shear-wall building was not expected to satisfy life safety performance levels under a design earthquake. In this study, one collapsed building was selected in order to test the reliability and usability of performance analysis methods under different earthquakes.

Forestry makes decisions based on one of the tactical planning applications for decades' years. Especially forested areas and rangeland provide very wide support to the world in terms of fresh air and food. In particular, World areas provide a wide range of support for living things in terms of naturalness and nutrition. Honey is not only a source of healing for humans but also the richness of the natural. Honey producing activities (beekeeping) was generally done in the open areas in and around the forest or rangeland. This study was carried out in Tercan Forest Planning Unit (FPU) in 2013 to determine the areas of beekeeping with the help of high-resolution aerial photographs. Placed hive areas for honey production had been identified in Tercan FPU. The distances of honey production areas and other areas to land use types were determined in GIS environment. Of these 95 beehive areas had found in Tercan Forest Planning Units. These hive areas were produced to buffer zone map that is respectively 0-500 m, 501-1000 m, 1001-1500 m and 1501-2000 m. Analysis to the distance of the hive areas with land use maps has been determined in GIS environment. The estimated amount of honey production has been tried to be rubbed over honey hive numbers. The location of honey casings is generally found in the land use classes, which are close to freshwater.

Tuncay, Birgul; Göger, Berrin
Objective: This study aimed to assess the digital game addiction and sleep quality in adolescents and examine the relationship between them. Materials and Methods: This descriptive study was conducted with 312 students from three high schools located in a district center in the Eastern Black Sea Region, who agreed to participate in the study. Data were collected using the descriptive information form, the digital game addiction scale, and the Pittsburgh sleep quality index. Results: The mean age of the participants was 15.99 +/- 0.85 years. Of the participants, 78.5% played digital games on computers, mobile phones, tablets, or game rooms. The mean score of the participants on the digital game addiction scale was 12.46 +/- 5.57; 16.3% were game addicts. The Pittsburgh sleep quality index mean score was 4.72 +/- 2.53, with a score range of 0-13; 34.9% had poor sleep quality. Conclusion: In conclusion, a positive, low-level, statistically significant relationship was found between the digital game addiction scale and Pittsburgh sleep quality index scores (r=0.157, p <= 0.001). As the digital game addiction scores increase in adolescents, their sleep quality scores also increase. Game addiction and sleep-related problems in adolescents can negatively affect their physical and psychological health and academic success. Adequate supervision and protective measures are required to reduce the problems faced by adolescents when using digital technology.

Denizli, Umut
This study examines the ethical implications ofcontemporary digital technologies for human existence, focusing on the semiotic construction of human-machine interaction in the anthology series Black Mirror. The research gap addressed in this article concerns the limited attention paid to the sign systems through which the series produces ethical meanings: while existing studies have discussed BlackMirror mainly as a thematic critique of technological dystopia, fewer have systematically examined how visual and verbal signs organise questions of consciousness, autonomy, surveillance, identity, and responsibility. To address this gap, the study uses a Saussurean and Peircean semiotic framework to analyse how selected episodes encode ethical problems at the intersection of organic and artificial life. The empirical corpus consists of fourteen purposively selected episodes from seasons 2-6, excluding the later seventh season released in 2025, and was examined through qualitative coding of visual and verbal signs related to consciousness transfer, artificial intelligence (AI), social media, virtual reality, surveillance, and digital vigilantism. The analysis identifies recurring oppositions between embodiment and disembodiment, autonomy and control, presence and mediation, and responsibility and outsourcing, which together articulate specific moral narratives about technological progress. The articles' original contribution lies in linking semiotic form to technological ethics: it shows how popular techno-dystopian fiction not only represents ethical problems thematically but also constructs them through recurring signs, oppositions, motifs, and narrative patterns. The findings suggest that Black Mirror foregrounds the fragility of human agency in technologically mediated environments and problematises unregulated innovation as a threat to dignity, privacy, and social cohesion within the selected corpus. The study concludes that these findings are interpretive insights from a purposively selected corpus, while also indicating the need for further research on how AI and related technologies are represented, governed, and ethically implemented in ways that protect human agency, dignity, and the broader public interest.

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.

Demir, Sertac Timur
In this article, everyday technology, which tends to expand without limits, is discussed in the context of contemporary practices that start from antenatal to death and that correspond to the desire for immortality of modern man. For this purpose, it is examined how technology intervenes in life and death through the episodes of Arkangel, Right Be Back, and San Junipero in Black Mirror, the popular science fiction series. In this study, the current social and human dilemmas that appear in the narratives are discussed, without ignoring the technical analysis of the series. In this respect, gene based medical studies that reformat the body, smart and synthetic technologies that add a new dimension to digital control and surveillance, contemporary medical and technoscientific assumptions about death and immortality are debated. The theoretical framework of this article consists of theoreticians such as Jean Baudrillard, David Le Breton and Byung Chul Han who consider that the change in social structure and relations is mainly driven by technology and critically approach this unavoidable trend. According to the main argument and inference of this research, technologies that can descend to every part of the body are no longer just the comfort and convenience extensions of daily lite, and they affect almost all ontological processes between existence and extinction by being articulated with human destiny. However, this global trend is also the loss of the natural and the real for the modern characters who are deprived of the human conditions such as pain and death that make life precious.
