  • A Study to Evaluate the Recreation Potential of Bentler Nature Park

    • Authors: Eren Dağra SÖKMEN; Ş. Doğanay YENER
      Abstract: Within the dense population and urbanization, natural areas in the cities are becoming more valuable as places where the recreation needs are met. Natural parks with visual value along with vegetation and wildlife also have an important place among natural areas. The aim of this study is to determine the recreation potential of the Bentler Natural Park in the Belgrad Forest, which has a variety of recreational opportunities such as picnics, hiking, cycling and nature photography. For this purpose, the Gülez Method which is often preferred in determining the recreation potential of forests was used. This method determines the recreation potential of the area by evaluating five elements: landscape value, climate value, accessibility, recreational convenience and negative factors in the recreation area. According to this; the recreation potential of Bentler Natural Park was evaluated and the recreation potential was determined to be 77% (very high). Various proposals have been made to increase the recreation potential by reducing negative factors in Bentler Natural Park by survey and user reviews.

  • Accessibility of the Elderly to Family Health Centers and Nearby Urban
           Activity Areas: The Case of Karşıyaka Neighborhoods (İzmir)

    • Authors: Fatma ŞENOL; Şevval MARAL, Rana Başak SERİM
      Abstract: Accessibility of urban activity areas by elderly individuals are important concerning their quality of life, socialization opportunities, and mental health as well as communal solidarity. Therefore, elderly people’s accessibility to these areas in daily routines must be provided. However, accessibility to these areas can show differences up to inequality between social groups due to spatial opportunities and individuals’ socio-economic and demographic characteristics. With these arguments, our study analyzes and evaluates elderly people’s accessibility to primarily family health centers (FHC) and other urban activity areas significant for the elderly in Karşıyaka neighborhoods (İzmir) with Geographical Information Systems tools. In the study, the urban activity areas include primarily the pharmacy, bakery, market, park, mosque, market area, and secondarily, the headman's office, post office, bank, and public transportation stations. The results show the differences in the accessibility across and within the neighborhoods and that the number of primary activity areas in close distance (210m) of FHCs is higher than that of the secondary areas.

  • Plant Asset in the Historical Spaces: Case of Diyarbakır, Turkey

    • Authors: Zeynep TOPRAK; Cengiz YÜCEDAĞ
      Abstract: In this study, it was aimed to determine and evaluate the plant asset in 12 mosques and 1 church in Sur -Diyarbakır. For this purpose, the plants in the study areas were identified, their dendrological characteristics were determined, their diameters were measured and their suitability for use in the historical space was evaluated. In the study, a total of 199 trees and shrubs were identified. The most common species in the study areas were eastern sycamore (Platanus orientalis L.) and white mulberry (Morus alba L.). In addition, it was found out that the protection works for study areas together with their surroundings were insufficient in terms of the improvement and protection of historical spaces. In this sense, misused species can be replaced with native plants in steppe vegetation.

  • Use of Lemon, Orange, Grapefruit and Pomegranate Fruit Peels Against
           Meloidogyne incognita (Kofoid and White, 1919) Chitwood, 1949

    • Authors: Fatma Gül GÖZE ÖZDEMİR
      Abstract: The mortality effect of single and combined applications of lemon, orange, grapefruit and pomegranate fruit peels aqueous extracts against Meloidogyne incognita second juvenile larvae (J2) and the nematostatic effect on suppression of hatching were investigated in this study. After 24h, the effect of aqueous extracts of only pomegranate and only grapefruit peels on J2 was found to be over 50%, while only orange fruit peel application (41.5%) was determined higher than only lemon application (18.7%). While the mortality effect of lemon peel aqueous extract on J2 was low after 24 h, 77.5% mortality was detected after 48 h. It was determined that all J2s were killed after 48 h in the combined applications of lemon+pomegranate, lemon+grapefruit, orange+pomegranate, orange+grapefruit and pomegranate+grapefruit peel aqueus extract, and their mortality effects were found to be similar to the nematicide Velum (Fluopyram). In single applications, the highest suppression on hatching was determined only in grapefruit (54.2%) peel aqueous extract. Egg hatch suppression was found to be over 57% in all combined applications. There was no statistically significant difference between the hatching suppression percentage of pomegranate+grapefruit (90.7%) peel aqueous extract application and Velum (98.5%) application (P≥0.05). These results support that lemon, orange, grapefruit and pomegranate peel aqueous extract applications are good alternatives to nematicides.

  • Ethics of Artificial Intelligence: Impact on Society

    • Authors: Tülay TURAN; Gökhan TURAN, Ecir KÜÇÜKSİLLE
      Abstract: We can define artificial intelligence systems as systems that serve the basic roles of society today, benefit us in many application areas, and can make autonomous decisions in the coming years, perhaps without the need for humans. In order for artificial intelligence systems to work with more and more autonomy, that is, with less human control, ethical structures must first be established. Ethical AI is AI that adheres to well-defined ethical guidelines regarding core values such as individual rights, privacy, equality and non-prejudice. Artificial intelligence ethical practices will help organizations operate more efficiently, produce cleaner products, reduce harmful environmental impacts, increase public safety and improve human health. Unethical artificial intelligence applications may cause serious harmful effects for society. The most important solution to responsibly manage these negative effects and direct artificial intelligence systems for the benefit of society is the development of ethical artificial intelligence systems. In recent years, studies on the ethics of artificial intelligence by academia, industry, government and civil society have begun to provide a basis. In this study, the ethics of artificial intelligence and its impact on society, labor market, inequality, privacy and prejudice are discussed, possible risks and threats are pointed out, and suggestions are made for solutions.

  • Evaluation of Silvicultural Practices in Kütahya Region Forest Fire
           Areas

    • Authors: Gülnur Saba ERTUĞRUL; Nebi BİLİR
      Abstract: Silvicultural practices of fire areas that were prioritized in afforestation with the relevant suggestions were studied in three sampled areas, which of each 1000 m² burned in 2007, forested by Anatolian black pine [Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe]. The areas sampled from Kütahya forest district were examined based on height, diameter at base, and age. Averages of height, diameter at base and age were 221.3 cm, 6.7 cm and 8.8 years, while numbers of trees were 189, 204 and 323 in sampled areas. Result of analysis of variance showed significant differences at 99% among the sampled areas for the characteristics. However, the areas were more heterogenous for height than diameter and age by Duncan’s multiple range test. Positive and significant correlations (p<0.01) were found among the characteristics by results of correlation analysis in the areas (r>0.52) and their total (r>0.37). Results of the study showed that silvicultural practices were well accordance for sustainable forestry purposes to contribute forestry practices such as fire culture.

           Lettuce Cultivation (Lactuca sativa var. capitata) in Soilless Culture

    • Authors: Özlem AKAT SARAÇOĞLU; Cenk Ceyhun KILIÇ
      Abstract: The research was determined that on yield and plant nutrients of three different salinity levels [(Control (EC0), Control +1 dS m-1 (EC1), Control +2 dS m-1 (EC2)] of head lettuce cultivation (Lactuca sativa var. capitata) with soilless culture. In order to reach the determined target, Bombola F1 variety was grown by using perlite medium in channels made of PE material. With this aim to achieve the specified goal, plant nutrient content were analyzed. In the I. production period, an average of 0,25 L plant-1 and 3.76 L plant-1 plant per day, II. In the production period, an average of 0.33-3.50 L plant-1 nutrient solution was applied. In the I. production period, the average amount of nutrient solution drained from the subjects was between 0.15-2.29 L per plant-1 and II. In the production period, it varied between 0.26-2.43 L plant-1. The main effect of salinity levels on the N, P, K, Mg, Zn and Mn contents of the head lettuce leaves made a statistically significant difference. The effect of salinity levels on the Ca, Fe and Cu contents of the head lettuce leaves was insignificant (p<0.05). It is possible to approach that soilless agriculture head lettuce cultivation can be carried out by using poor quality and salt irrigation waters with a certain concentration.

  • Current Spatial Planning Decisions on Areas Prone to Disaster in Hydro -
           Meteorological Characteristic: The Case of Serik (Antalya)

    • Authors: Zübeyde Betül PANCAR; Duygu GÖKCE
      Abstract: Cities are vulnerable due to spatial planning decisions that lead to climate change, as well as inadequacies in the capacity to cope with the negative effects of climate change. Therefore, each city is faced with different types and levels of disasters, depending on its geographical and climatic characteristics. Dense and less spaced settlements based on current planning and urbanization practices, impermeable surfaces, inadequacies in drainage systems increase the risk of flood and overflow disasters with hydro-meteorological character in cities. According to the Meteorological Disasters Evaluation Report (2020), the disasters that most affect the world at a rate of 44% and our country with a rate of 30% are floods and overflows. In addition, Antalya is one of the provinces where these disasters are seen the most. Serik district of Antalya, on the other hand, is vulnerable to flood and overflow risks due to its geographical and climatic features, river beds, disadvantaged population, tourism-based development, scarcity of permeable surfaces, and infrastructure capacity. In this context, the risky areas and risk levels of the Serik settlement, which is under the threat of flood and overflow, that will be damaged during a disaster have been analyzed. Then, the spatial plan decisions taken in the risky areas were evaluated by overlapping the analysis maps with the 1/25.000 scale master development plan of Serik district. Accordingly, in the plan, it has been determined that “very high risk” and “high risk” areas where the use of existing housing area, housing development area, trade-tourism-housing area, collective workplace, archaeological site and agricultural land are concentrated are the most vulnerable areas of the settlement.

  • Temporal and Spatial Distribution of Outdoor Thermal Comfort Conditions:
           The Case of Konyaaltı-Antalya, Turkey

    • Authors: Nihat KARAKUŞ; Serdar SELİM
      Abstract: Outdoor thermal comfort in cities has started to gain more importance with increasing temperatures in urban environments. In this study, it is aimed to determine the temporal and spatial distribution of outdoor thermal comfort conditions in Konyaaltı district of Antalya province. For this purpose, firstly, climate data (temperature, humidity, wind speed and cloudiness) were obtained from meteorology observation stations in Konyaaltı district and its immediate surroundings. In the study, outdoor thermal comfort conditions were calculated using PET (Physiological Equivalent Temperature) and RayMan model, which is one of the most widely used thermal comfort indices, which includes human energy balance as well as climate parameters. Spatial distribution of monthly PET values produced using RayMan Model was obtained using IDW analysis in GIS. As a result, thermal comfort conditions are partially formed in the spring and autumn seasons in Konyaaltı city center and its vicinity, and thermal comfort conditions are not suitable in other seasons due to hot and cold stress.

  • Use of PowerWorld Simulator in Learning Power Flow Analysis: A
           Computer-Aided Visualization Tool

    • Authors: Ahmet ÇİFCİ
      Abstract: The rapid development of renewable energy sources, the integration of distributed generation facilities, and advances in digitalization are causing a complex transformation in power systems around the world. The complexity of power systems makes power systems studies tedious, difficult and time-consuming for both undergraduate and graduate students. However, the use of simulation tools has greatly simplified the computational operations associated with power systems studies. Power flow studies are becoming increasingly necessary to evaluate not only the operation of the power system under current operating conditions but also the plan and design of future expansions. This paper provides a review of power flow analysis with PowerWorld Simulator, which uses advanced visualization techniques to assist students in better understanding complex phenomena in power systems. For this purpose, power flow analysis of Stevenson’s 5 bus power system was investigated by Newton-Raphson, Gauss-Seidel and Fast Decoupled methods. The simulation results are given both visually and as a table. As a result, it has been seen that with PowerWorld Simulator, students will better understand power system analysis problems in addition to traditional solutions.

  • Examination of Transformation in Historical Buildings within the Context
           of Worship Buildings

    • Authors: Sevim ATEŞ CAN; Şükran KARABACAK
      Abstract: Historical buildings are social richness that brings the cultural, social and economic characteristics of the period. Historical places of worship are important places that are symbols of cities. Changing conditions over time cause the original functions of historical buildings to disappear, and some interventions may be required for the buildings to be reused. In the study, the intervention approaches applied to historical places of worship are examined by dividing them into groups as additional design, the transformation of the interior by preserving the facade, and the application of completion, around the phenomenon of transformation. These approaches are discussed through selected examples from the world and our country. In the changing process, a study has been created that gives information in the light of applied examples about the intervention of transforming the historical structure by adding new meanings to the historical structure without harming the identity of the historical buildings. The aim of the study is to establish the awareness of conservation and to try to create a contemporary perspective in interventions as a result of examining the conversion practices in historical places of worship.
