Temir, Münevver
Tarım aracısı, tarımda iş ve işçi bulma aracılığı faaliyetini yürütmek üzere Türkiye İş Kurumu tarafından izin verilen gerçek veya tüzel kişidir. Tarımda İş Aracılığı Yönetmeliği ile tarım aracılarına; işverenle sözleşme yapmak, işçilere iş, ücret ve ilgili konularda bilgi vermek, ücretlerin zamanında ödenmesini ve asgari ücretin altında olmamasını sağlamak, ulaşımın güvenli seyri için önlem alınmasını takip etmek, işçilerin konaklama yerlerinin sağlığa uygun olmasını temin etmek gibi birtakım görevler yüklenmiştir. Anılan yükümlülüklerden bazılarının gerçekçi ve makul nitelikte olmadığı söylenebilir. Ayrıca aracıların önemli bir bölümünün yasal koşulları sağlamaksızın kayıt dışı faaliyet yürüttüğü bilinmektedir. Bu yönüyle, tarımda iş ve işçi bulma aracılığı faaliyeti hukuken istenilen düzeyde değildir. Tarım aracılığında işçi, işveren ve aracı ilişkilerinin henüz hiçbir yönden esaslı bir şekilde düzenlenmemiş olması, yapılan bazı düzenlemelerin ise denetiminin olmaması, mevsimlik tarım işçileri için emniyetsiz bir çalışma hayatına sebebiyet vermektedir. Bu çalışma, tarımda iş ve işçi bulma aracılığının mevcut durumunu, yasal çerçevesini ve aracı yükümlülüklerinin mevsimlik tarım işçilerinin çalışma koşullarına etkisini iş hukuku boyutuyla açıklığa kavuşturmayı amaçlamaktadır.

Şen Özdemir, Nurgül; Aydın, Erdinç; Sokmen, Teoman Ozgur
Length-weight relationships (LWRs) and Fulton condition factor (CF) of 8 fish species belonging to different families (Bilicca bjoerkna, Scardinus erythrophthalmus and Carassius gibelio from Cyprinidae, Esox lucius from Esocidae, Silurus glanis from Siluridae, Perca fuliviatilis from Percidae, Abramis brama from Leuciscidae) obtained from commercial fishermen in Çaltıcak (Taşkısığı) Lake (Sakarya/Türkiye) were examined. LWRs and CF of the fish species were analyzed between March 2021 and March 2022. C. gibelio and E. lucius show positive allometric growth, B. bjoerkna,S. glanis and P. fuliviatilis and A. brama showed negative allometric growth, while S. erythrophthalmus and T. tinca show isometric growth. The lowest CF values of the fish species were also determined in S. glanis (0.62) and E. lucius (0.69). It is thought that the information obtained in the study about the LWRs and CF values of the fish species in Çaltıcak Lake will be beneficial for commercial fishing and fisheries management in the region.

This study aimed to determine the socio-demographic and economic characteristics, monthly expenditures, and meat and fish consumption patterns of teachers working in the city center of Bingöl Province. The data for the study were collected through face-to-face interviews conducted with teachers working in the city center of Bingöl between May 2023 and July 2023. According to the findings of the study, the average monthly net household income was calculated as 23984.596₺, the average monthly expenditure was 14906.215₺, the average monthly food expenditure was 5783.475₺, and the average monthly fish expenditure was 436.57₺. It was determined that the monthly fish consumption quantity of the surveyed teachers ranged from 1 kg to 2.66 kg, with an average of 2.54 kg, and they purchased trout from a fixed vendor during the winter months and consumed them baked in the oven, but this consumption amount was not sufficient for them. It was concluded that the tendency of the surveyed teachers to increase fish consumption was more strongly related to the decrease in fish prices rather than an increase in income. In other words, teachers expect a decrease in fish prices rather than an increase in their income to increase fish consumption. In conclusion, increasing the consumption of aquatic products, both in Bingöl and throughout Türkiye, is an important step that could have positive effects on health, and collaboration among various stakeholders is necessary to achieve this goal.

Yangılar, Filiz; Okcu, Zühal
In the current study, four different types of yogurt were produced as control samples (no MPP added) and 1, 2, and 3% melon peel powder (MPP1, MPP2, and MPP3). These yogurts were determined by physicochemical, microbiological, sensory, total phenolic, and antioxidant activity weekly for 21 days. While ash, moisture, titratable acidity (TA), viscosity, water holding capacity (WHC), a* and b* values, total phenolic content (TPC), and antioxidant capacity of melon peel powder samples increased, L*, pH, and syneresis values decreased. In concentrations of 1, 2, and 3%, the mean antioxidant activity of powdered yogurt was found to have average values during storage of 30.09%, 32.32%, and 36.26%, respectively. All yogurts continued to contain more than 107 cfu/g of live lactic acid bacteria during fermentation. As the storage time increased, the sample’s pH and syneresis decreased, while titration acidity and texture increased. No yeast or mold (2 log cfu/g) was determined in the samples. The panelists preferred MPP1 and MPP2 samples. According to the findings of the study, melon rind powder, which is a by-product, can be recommended as a functional food additive in yogurts.

In this study, some agro-food processing by-products were evaluated as novel food ingredients, that meet the consumer's demand for natural ingredients, and their contributions to chicken-type sausage production were examined. Sausages were formulated with 3% quince waste (QS3), 3% grapefruit waste (GS3), 2% tomato waste (TS2), and 3% tomato waste (TS3). Other ingredients were fresh breast chicken meat, beef tallow, spice mix, ice, NaCl, and NaNO2. Proximate composition and sensory analyses were conducted before the storage. Water activity, pH, TBARS, purge accumulation, and microbiological analyses were performed during the storage. QS3, TS2, and TS3 treatments got appreciated (7.0-7.4 out of 10) sensory scores, while GS3 scored low acceptability (4.0 out of 10) points. Adding food waste significantly reduced purge accumulation; the average purge accumulation of the control sample was 3.70% which is approximately two times higher than food waste added samples. The average TBARS value of the control sample was determined as 0.31 mg MA/kg, and the food waste-added samples were found between 0.57-0.65 mg MA/kg during storage. Total mesophilic aerobic bacteria and yeast-mold load were higher in TS2 and TS3 products; microbial load and TBARS values of food waste affected the product quality. Also, water activity, microbial growth, and purge accumulation amount affected each other during storage.

Using 59 years of pistachio production data between 1961 and 2019, the production data of the leading countries in the 2020-2025 periods were tried to be predicted with the help of the ARIMA time series model. ARIMA (p, d, q) analysis model has been used by obtaining 59 years of production data from the United Nations Food and Agriculture Organization (FAO). In addition, the data obtained from the Turkish Statistical Institute (TSI), FAO, and the International Trade Centre (ITC) were also used in the comparison of production, export, and import per capita. In the study, the world production data for the period of 2020-2025 were to be estimated with the data between 1961-2019. As a result of the findings obtained, according to the data obtained in the world, Iran, USA, Turkey, China, and Syria, an increase in production is foreseen in all countries and the world where studies are carried out in pistachio production. While the share of the five countries, which are the leaders in Pistachio production between 1961 and 2019, in the total world production is 97.99%, the share of Pistachio production between 2020-2025 in the total production is expected to be 97.51%. While the share of Iran and Syria from these five countries in world production will decrease, the share of the USA, Turkey, and China will increase. The two leading countries in pistachio exports are Iran and the USA. The fact that Germany, which does not influence production, has a significant share in both exports and imports brings to mind the derivative demand situation. Turkey, Iran, and Syria can create a better marketing strategy by reducing imports to Germany and increasing exports to European Union countries.

Objectives The incidence and mortality of gastrointestinal (GI) malignancies increase exponentially with age. Malnutrition is a documented poor prognostic factor in older patients with cancer. There is insufficient data about the prevalence of malnutrition and associated factors in older patients with GI cancer. Thus, we aimed to investigate the prevalence of malnutrition and related factors among older patients with GI cancer. Methods A total of 121 patients aged over 70 years diagnosed with various types of GI cancers applied to the medical oncology clinic included in this cross-sectional study. We evaluated the nutrition status with a mininutritional assessment (MNA) score. Results The prevalence of malnutrition was 76 (62.8%) in our study population. The mean age was 76.5 (range 70 to 90 years), and 71 (58.6%) were male. In the multivariate logistic regression model, lower BMI (OR: 3.379, 95% CI: 1.465-7.812, p = 0.005), having gastroesophageal cancer (OR: 5.797, 95% CI: 2.387-14.091, p <0.001), treating with palliative chemotherapy (OR: 4.597, 95% CI: 1.799-11.772, p = 0.002), and frailty according to G8 score (OR: 10.798, 95% CI: 4.495-25.924, p <0.001) were associated with malnutrition. Conclusions Our study revealed that palliative chemotherapy, low BMI, frailty, and gastroesophageal cancer are risk factors for malnutrition in older patients with GI cancer. Physicians need to be aware of patients who may be at risk for malnutrition. Patients at risk of malnutrition may benefit from interventions to enhance their nutrition. Further studies consisting of larger cohorts are needed to determine malnutrition and related factors in older patients with cancer.

Elveren, Müjgan
Due to increased consumption, artificial sweeteners are often present in the environment but their effects on plants are largly unknown. In this research, the effects of four artificial sweeteners on plant stress markers in Triticum aestivum L. were investigated. Wheat seedlings were grown from seeds in soil containing artificial sweeteners (saccharin, sodium cyclamate, sucralose, aspartame) in different concentrations (0, 25, 50, 100 mg kg–1). Plants were irrigated at regular intervals to maintain field capacity moisture and harvested after 15 days of growth. Electrolyte leakage, chlorophyll and carotenoid content, and antioxidant enzyme (superoxide dismutase, peroxidase, catalase) activities were determined in harvested leaves. Comparisons between control samples and test samples were statistically evaluated at a 95% confidence interval to determine significant differences. Overall, significant increases in chlorophyll and carotenoid content, and some antioxidant enzyme activities were observed in wheat plants exposed to artificial sweeteners in the soil. A significant increase in electrolyte leakage was observed with saccharin and aspartame treatment, indicating that these sweeteners can cause membrane damage in wheat. Chlorophyll a and POX activity were the most sensitive stress parameters in wheat. This study showed the importance of evaluating the potential impact of anthropogenic pollutants that may be present in treated wastewater and consequently affect plants.

Fructose content varied significantly, with the “F + T + C + E” treatment showing the highest (11.4 g.L-1) and the “CT” group the lowest (2.5 g.L-1). Rhamnose content in the curative treatment reached 14.9 g.L-1 (“F + T”) and in the protective treatment, the “C + E + F” group had the highest (3.3 g.L-1). Galactose content ranged from 0.1 to 13.0 g.L-1. Xylose content in curative treatment ranged from 12.1 to 13.6 g.L-1, with the combination “F + T” displaying the highest. In preventive treatment, arabinose content ranged from 0.7 to 3.0 g.L-1, with the “T + C + F” group having the highest. In terms of vitamins, the combination “T + F” showed the highest B1 (25.4 mg.100 g-1) and B2 (24.6 mg.100 g-1) content. Vitamin A, B1, and B2 increased in the “F + T” group, and vitamin C increased in the “F + T + C” group (33.4 mg.100 g-1). The quantification of oxidative stress markers and antioxidant enzymes revealed significant reductions in H2O2, MDA, and proline levels in EOC applications. In preventive treatment, the combination “T + C + E + F” exhibited the most effective improvement in SOD activity (556.5 EU mg-1), CAT activity increased significantly in the “T + C + F” group (189.3 EU mg-1), and APX activity saw the highest increase in the “T + C + E + F” group (185.6 EU mg-1). Contrastingly, curative treatments showed higher H2O2, MDA, and proline levels. The most significant decrease in H2O2 level occurred in the “T + C + E + F” group (36.7 nmol.g-1), and a significant decrease in MDA level was noted in the same group. Notable changes were observed in the activities of antioxidant enzymes, with the “F + T + C + E” group displaying the highest SOD activity (440.7 EU mg-1), and the “F + T” group showing the highest GST activity (542.0 EU mg-1). This research provided comprehensive insights into the biochemical responses of apple fruits to EOC treatments, offering potential strategies for effective fungal management in agriculture.

The Erzincan (Cimin) grape, which is an endemic product, plays a significant role in the economy of both the region it is cultivated in and the overall country. Therefore, it is crucial to closely monitor and promote this product. The objective of this study was to analyze the spatial distribution of vineyards by utilizing advanced machine learning and deep learning algorithms to classify high-resolution satellite images. A deep learning model based on a 3D Convolutional Neural Network (CNN) was developed for vineyard classification. The proposed model was compared with traditional machine learning algorithms, specifically Support Vector Machine (SVM), Random Forest (RF), and Rotation Forest (ROTF). The accuracy of the classifications was assessed through error matrices, kappa analysis, and McNemar tests. The best overall classification accuracies and kappa values were achieved by the 3D CNN and RF methods, with scores of 86.47% (0.8308) and 70.53% (0.6279) respectively. Notably, when Gabor texture features were incorporated, the accuracy of the RF method increased to 75.94% (0.6364). Nevertheless, the 3D CNN classifier outperformed all others, yielding the highest classification accuracy with an 11% advantage (86.47%). The statistical analysis using McNemar's test confirmed that the χ2 values for all classification outcomes exceeded 3.84 at the 95% confidence interval, indicating a significant enhancement in classification accuracy provided by the 3D CNN classifier. Additionally, the 3D CNN method demonstrated successful classification performance, as evidenced by the minimum-maximum F1-score (0.79-0.97), specificity (0.95-0.99), and accuracy (0.91-0.99) values.

Abstract: Predicting groundwater level (GWL) fluctuations, which act as a reserve water reservoir, particularly in arid and semi-arid climates, is vital in water resources management and planning. Within the scope of current research, a novel hybrid algorithm is proposed for estimating GWL values in the Tabriz plain of Iran by combining the artificial neural network (ANN) algorithm with newly developed nature-inspired Coot and Honey Badger metaheuristic optimization algorithms. Various combinations of meteorological data such as temperature, evaporation, and precipitation, previous GWL values, and the month and year values of the data were used to evaluate the algorithm’s success. Furthermore, the Shannon entropy of model performance was assessed according to 44 different statistical indicators, classified into two classes: accuracy and error. Hence, based on the high value of Shannon entropy, the best statistical indicator was selected. The results of the best model and the best scenario were analyzed. Results indicated that value of Shannon entropy is higher for the accuracy class than error class. Also, for accuracy and error class, respectively, Akaike information criterion (AIC) and residual sum of squares (RSS) indexes with the highest entropy value which is equal to 12.72 and 7.3 are the best indicators of both classes, and Legate-McCabe efficiency (LME) and normalized root mean square error-mean (NRMSE-Mean) indexes with the lowest entropy value which is equal to 3.7 and − 8.3 are the worst indicators of both classes. According to the evaluation best indicator results in the testing phase, the AIC indicator value for HBA-ANN, COOT-ANN, and the standalone ANN models is equal to − 344, − 332.8, and − 175.8, respectively. Furthermore, it was revealed that the proposed metaheuristic algorithms significantly improve the performance of the standalone ANN model and offer satisfactory GWL prediction results. Finally, it was concluded that the Honey Badger optimization algorithm showed superior results than the Coot optimization algorithm in GWL prediction. Graphical Abstract: (Figure presented.).

Predicting the groundwater level (GWL) is essential in water resource management and irrigation planning in arid and semi-arid areas. In this study, an artificial neural network (ANN) was combined with newly developed wild horse optimizer (WHO) and egret swarm optimization algorithm (ESOA) techniques to predict a one month lead-time GWL in the Tabriz plain of Iran. For the prediction of the GWL, the number of months and years, the one month lag of average temperature, evaporation, precipitation, and GWL were used as inputs. Model performances were compared using root mean square error (RMSE), Nash–Sutcliffe efficiency (NSE), coefficient of determination (R2), and relative strength ratio (RSR) statistical indicators and scatter diagrams, time series graph, violin graph, and Taylor diagram. As a result of the analysis, the most successful estimation results were obtained with the input combinations of year, month, average temperature, evaporation, precipitation, and GWL (t − 1) for the prediction of the one month lead-time GWL. According to the results of evaluation indicators in the testing phase, ANN with (R2 = 0.871, RMSE = 0.306 (m), NSE = 0.832, and RSR = 0.410), WHO–ANN (R2 = 0.932, RMSE = 0.200 (m), NSE = 0.929, and RSR = 0.267), and ESOA–ANN (R2 = 0.952, RMSE = 0.164 (m), NSE = 0.951, and RSR = 0.220). In addition, it was revealed that the ESOA–ANN hybrid model showed higher prediction success than the WHO–ANN and standalone ANN models. The study outputs contribute to decision-makers and planners for controlling land subsidence, assessing GWL and aquifer compaction, irrigation planning, and effective management of water resources.
