Decreasing NCDs and supporting healthy, high-quality urban environments is one of the United Nations’ Sustainable Development Goals (SDGs). In particular, diabetes is related to quality of life and physical activity, making the disease more responsive to built environment factors. This study examines the geographical distribution of diabetes disease rate and its risk factors across Turkish cities. Principal component analysis and spatial regression models are used for this purpose. It is observed that open green spaces with high accessibility can increase physical activity and thus have a reducing effect on diabetes prevalence. In addition, in cities with sufficient healthcare services per capita, diabetes prevalence is lower. On the other hand, private vehicle ownership can have an increasing effect on diabetes prevalence, and a high share of the elderly population can be another reason for high diagnosis. According to the study findings, planning settlements with high open green spaces prioritizing open green space development, public transportation and non-motorized vehicles, and accessible healthcare facilities can reduce diabetes risk factors by promoting physical activity and increased mobility along with a positive planning and design approach for public health. Elderlyfriendly planning specifications need prioritization for some cities. This study presents evidence for the necessity of urban policies and public health strategies prioritizing health and physical activity in urban built environments.

For hatchlings with a female:male ratio of 1:1, the pivotal temperature is usually around 29°C, with female hatchlings being observed at higher values and male ones at lower values. It is expected that wildlife threatened by global warming will be more severely affected, especially species that sex is determined by temperature. This study was carried out by measuring air, sand and nest temperatures during 2008 and 2009 nesting seasons at Kazanlı Beach, one of the largest nesting sites of Chelonia mydas (Green turtle) in the Mediterranean. Sand grain size was also measured, and gonads of dead hatchlings were examined histologically. Both sand (n=4) and nest (n=6) temperatures were above the pivotal temperature (between 29.131.6°C) in the study area. According to the estimation based on temperatures, hatchlings were female (♀>50%) biased. Of the hatchling samples, 75 were examined histologically. According to histological examination, the female:male ratio was 2:1. According to the direct examination and indirect estimation; the sex ratio of green turtle hatchlings in Kazanlı Beach, one of the highest hatchling producing nesting sites of the Mediterranean, was reported for the first time in this study. There is a need to fill the data gaps regarding sex ratios, especially for major beaches with high hatchling production. Knowing the temperature profiles in and around the nest and sex ratios of hatchlings is critical for the development of conservation measures for endangered sea turtles.

Transportation directly shapes the socio-economic framework of metropolitan areas. To address the complexities of transportation in Ankara, the study introduces a hybrid approach by integrating the Fuzzy CRITIC (Criteria Importance Through Inter-Criteria Correlation) method with the novel Pythagorean Fuzzy Weighted Sum Method. This novel approach assesses the various transportation modes available in Ankara, taking into account pivotal criteria such as cost, duration, reliability, comfort, and flexibility. The hybridized methodology offers a systematic way to determine the weights of each criterion. Then, leveraging these weights, the performance of each transportation mode is calculated and ranked. This integrated approach proves to be a powerful analytical tool for addressing multicriteria decision-making challenges, especially when confronted with uncertainty and intricate details. The outcomes of this research aim to serve as a cornerstone for the Ankara Ministry of Transportation and other key stakeholders. The insights derived can be pivotal for enhancing the existing transportation infrastructure or for the initiation of new, more efficient projects. This study highlights the effectiveness of hybrid decision-making methods for urban transportation, setting a benchmark for similar challenges. It presents a strategic, analytical approach to streamline Ankara's transportation, addressing its complex urban transport needs.

The most important parameter used to express the strength of rocks is the uniaxial compressive strength (UCS). However, in some cases it can be quite difficult to determine the UCS. For example, when it is difficult to obtain rock specimens of the required size for UCS testing, indirect methods such as point load strength and ultrasonic wave velocity are used to estimate UCS. If the UCS is determined incorrectly, this can lead to irreversible design errors, project delays and financial losses. PLI testing is performed on specimens of different shapes as well as on specimens of different sizes. This study investigates the ability of the values obtained as a result of PLI tests on specimens prepared with different diameter/length (D/L) ratios to predict UCS. For this purpose, PLI experiments were performed on seven different carbonate rocks prepared at different D/L ratios. The relationships between the obtained values and the UCS values of the rocks were analyzed. High correlations were obtained between PLI and UCS values and it was observed that D/L ratio has no significant effect on UCS estimation.
