    Kentlerin Depreme Dirençliliğinin Bina Bazlı Bölgesel Risk Dağılımı Yöntemi İle İncelenmesi: İzmit Kenti Örneği
    (Afet ve Acil Durum Yonetimi Baskanligi, 2024) Kurt, Deniz Gerçek; Guven, Ismaıl Talıh; Erdogan, Hakan
    Türkiye, yıkıcı deprem üretme potansiyeli yüksek fay hatlarının yer aldığı bir bölgede konumlanmaktadır. Tarih boyunca, Anadolu yarımadasında meydana gelen depremler büyük can ve mal kayıplarına sebep olmuştur. Bu bağlamda, nüfusun ve sanayileşmenin çok yoğun olduğu Marmara Bölgesinde deprem risk değerlendirme çalışmalarının yoğunlaşması ve gerekli önlemlerin alınması büyük önem arz etmektedir. Bu çalışmada, 6306 sayılı \"Afet Riski Altındaki Alanların Dönüştürülmesi Hakkında Kanun\" kapsamında tanımlanan binaların bölgesel deprem riski dağılımının belirlenmesi için riskli yapıların tespitine ilişkin esaslar başlığı altında öngörülen basitleştirilmiş yöntemler kullanılarak Kocaeli ili İzmit ilçesinde bulunan 19940 bina incelenmiştir. Söz konusu yöntem, hızlı sokak taraması prensiplerini dikkate alarak bölgesel deprem risk önceliklendirmesini hedeflemektedir. Saha incelemelerinden elde edilen sonuçlar, nüfus yoğunluğu ve dağılımı, acil toplanma alanı dağılımı, toplam yapı alanı gibi parametrelerle beraber değerlendirilerek İzmit ilçesinde deprem risk öncelikli bölgelerin belirlenmesine çalışılmıştır.

    Evaluation of the Effects of Covid-19 Lockdowns and Strict Restrictions on İstanbul's Air Quality
    (İstanbul Teknik Üniversitesi, 2023) Köse, Şüheda
    The Covid-19 pandemic, which started in Wuhan, China, led to several strict restrictions and lockdowns in Turkey, like many other countries. Although lockdowns have had a socially and economically negative impact, they have affected the air quality in a positive way. The aim of this study is to examine the spatial impact of lockdowns on air quality in İstanbul and to determine the correlation of polluting indicators. In line with the determined purpose, PM10, SO2, NO2, CO and NOx parameters were spatialized with ordinary kriging method in 5 different time intervals and the relativity levels between meteorology, transportation and particles that cause pollution were examined with the Pearson correlation method. As a result, lockdowns caused an increase on CO and SO2 by up to 28%, while other particles decreased by 2% to 23%. Compared to 2019, a decrease of up to 60% in all particles except CO and SO2 has shown that lockdowns have a positive effect on air quality. It was observed that the pollution, which was concentrated in urban areas before the pandemic, spread to rural areas with the precautions taken. Temperature, number of vehicles and traffic index were found to play an important role in the emission of particles, while wind speed and direction played an important role in the displacement of pollution. It has been observed that finding a positive correlation between pollutants and the factors that trigger pollution has rapidly changed the ecosystem of the city along with the policies affecting air quality. © 2023, Istanbul Teknik Universitesi, Faculty of Architecture.

    User Satisfactions on Visual Comfort and View Quality Based on Colours and Opacity of Glazing To Control Daylighting
    (Znack Publishing House, 2023) Cogul, Ilgin; Duran, Hasan Engin; Kazanasmaz, Zehra Tugce
    Windows are both components that open to the outside and gates that bring the outside elements inside as well. The visible view through windows affects users' perception of the indoor environment. Visual comfort is a key concern to create qualified interior spaces. Glazing type in naturally lit environments becomes very substantial for comfort. As glazing technologies develop, the options available for users have also increased. This study aims to find out how different glazing and view types impact user perception and satisfaction in the interior and to create design ideas for the spaces to be completed in the future. A room with various glazing transmittance (20 %, 50 %, and 90 %), colours (blue and yellow), and view types (street and landscape) are modelled virtually in Relux. A survey composed of these rendered scenes from these variations includes four questions. 40 people participated in the survey. Statistical analyses are made using Stata and EViews. Illuminance and luminance are calculated via Relux to discuss quantifiable values and subjective one together. According to the results, as transmittance increase, the rate of people finding the room pleasant and the quality of the view decrease, but a brighter environment shows up. When using tinted glazing, users mark the rooms as interesting, while pleasantness and view quality decrease. A landscape view instead of a street view in the rooms results is a more interesting, pleasant indoor environment, and higher view satisfaction.

    Insights for the Enhancement of Urban Biodiversity Using Nature-Based Solutions: the Role of Urban Spaces in Green Infrastructures Design
    (Springer, 2022) Ronchi, Silvia; Salata, Stefano
    Nature-Based Solutions (NBS) increase their efficacy if included in an overall framework such as Green Infrastructures (GI), maximising ecosystem benefits and avoiding possible negative externalities and trade-offs. Urban green spaces and NBS are components of GI that increase the quality of urban settings, enhancing territorial resilience, and improving the health and well-being of citizens. The research proposes a methodology, tested in the municipality of Settimo Torinese (North-west of Italy), for selecting urban green spaces with high performance in terms of biodiversity conservation, which can involve a GI strategy as a multifunctional structure that combines different Ecosystem Services (ES). The enhancement of natural capital and ES provision is reached identifying suitable NBS to protect and improve biodiversity based on the Habitat Quality (HQ) assessment, considered a key supporting service. HQ was derived testing two different sensitivity data: the first based on Land Use/Land Cover, while the second uses the Normalised Difference Vegetation Index. The latter was functional to overcome limits in representing the ecologic integrity of urban areas highlighting an important variety of green spaces and related ES, especially in compact cities. The results are useful for defining effective environmental policies and strategies in urban areas and addressing the decision-making process towards sustainable development goals. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Contradicting Parochial Realms in Neighborhood Parks: How the Park Attributes Shape Women’s Park Use
    (İstanbul Teknik Üniversitesi, 2023) Kaştaş-uzun, İpek; Şenol, Fatma
    Neighborhood parks are significant green public spaces located in close social and geographical proximity to homes to maintain individual and public health. However, some people do not use the nearest parks, but those with other socio- spatial attributes that make them feel more “familiar”. This study argues that with their facilities, amenities and design, and the surrounding land uses, neighborhood parks do not only accommodate, but also define, regulate, and originate social relations among users. Thus, the design and planning of urban public spaces play a role in the emergence and maintenance of supportive and conflictual relations that lead to familiarity. The study answers two research questions: How do the park attributes shape and mediate the interpersonal relations among the park users? How do gender differences influence the parochial realms in parks? Data was collected through field observations and in-depth interviews with 33 female users of two neighborhood parks in a populous district of Izmir (Turkey). Results state that women’s park visits were related to their gendered roles and responsibilities. Yet their responses point to challenges emerging from physical and social attributes of parks and park surroundings which lead to negotiations to protect their individual or group’s privacy (parochial realm) in neighborhood parks. Mainly, perceived threats to women’s parochial realm are men unaccompanied by child(ren), and exposure to the male gaze. The study highlights the importance of investigating these attributes of neighborhood parks for developing research and public policies to improve women’s presence and perceived safety in public settings.

    Creating Spaces for Art: Long Term Impacts of Street Art in the Urban Context
    (İstanbul Teknik Üniversitesi, 2022) Kolçak, Emre; Kaya Erol, Nursen
    Street art can be defined as any informal artistic performances or artworks practiced in the public spaces. Street art has the potential to transform the public spaces by contributing to or reducing the quality of these spaces. Through street art, in many cases, public spaces are transformed into places for entertainment, cultural activities, or areas of protests and expression of the feelings and ideas. The impacts of street art practices might be limited to one part of an open space or spread to a district or even to the entire city depending on its temporal dimen-sion. This article aims to examine the relationship of street art and public space. In this context, the article overviews the concept of street art and demonstrates its positive, negative and temporal impacts on public space. This study uses a case study approach and evaluates the long term impacts of street art practices based on the analysis of three cases in the city of İzmir, Turkey. In İzmir cases it is found out that the street art practices transformed the public space in terms of uses, activities and built environment quality and had impacts on economic and social structure of the community. The findings of this study reveal that street art holds the potential of contributing to the city life through creating spaces for artistic activities and moreover of changing the meaning and identity of the public spaces and the settlements.

    Designing Healthier Cities. an Empirical Study of the Ecosystem Functioning and Mortality in the Districts of Turin (italy)
    (Springer, 2022) Salata, Stefano
    The twenty-first century is called “the age of the metropolises and cities” as they become the predominant living environments of human beings. Nonetheless, metropolitan areas are more vulnerable, for their intrinsic nature is dense and interconnected. The experience from the COVID-19 crisis teaches us how an epidemic outburst has been generated by reducing habitat at the planetary scale, and how the quality of the environment even affects the diffusion of the virus. But what is the relation between Health and Nature in urban areas? Is this relation so evident? Within this study, a preliminary assessment of the relations between urban environment and health will be evaluated by modelling the spatial distribution of the Habitat Quality in Turin and the mortality rates in the same areas. Data will be gathered at their maximum spatial precision, thus obtaining a reliable map of the distribution between the two indicators at the district level. Habitat Quality will be composed by the value of the supporting biophysical function and anthropic threats. Health will be evaluated using the death number in the statistical units and the accessibility of citizens to green areas. An overall assessment will be finally presented considering the simultaneous evaluation of spatial clusters and delineating how conservation and valorization measures can benefit from a site-specific evaluation of Ecosystem Services, while revealing their effects on human health.

    Evaluation of the Location Choice of Software Industry in Istanbul Based on the Types of Economy
    (İstanbul Teknik Üniversitesi, 2022) Köse, Şüheda; Berkoz, Ayşe Lale
    One of the main fields of economic growth in developing countries is the software industry, which is one of the innovative industries. Istanbul has a great potential for software creation with its artistic potential, its unique cultural heritage, social networks, and engagement. The purpose of this article is to explore the clustering pattern of Istanbul’s software industry and the choice of location from a spatial perspective, based on the types of economy. Three important conclusions have been reached by studying the spatial activity trends of the industry. Results include: (i) the software industry has a polycentric cluster pattern in the historical city center axis, (ii) a seat for the technological parks of particularly prestigious Universities in the center, and (iii) a chosen location in the center of town to benefit from the artistic industry. The results of this study will be a guide to the potential that will lead to the creative economy’s growth in Istanbul’s future plans.

    Urban Protection And Renewal Dilemma: İzmir Mezarlıkbaşı
    (İstanbul Teknik Üniversitesi, 2021) Akpınar, Figen; Turan, Mine; Toköz, Özge Deniz
    At the beginning of the 21st century, efforts to preserve cultural heritage in historical settlements is a highly problematic and multi-faceted issue in Turkey. Al-though conservation legislation dates back to 60 years ago, heritage conservation has not been internalized and accepted in the wider part of society, and, has not established a sound political foundation. On the other, however, there is also a lack of integrated land-use planning and management. The purpose of this study is to present the difficulties of dealing with the conservation, renewal, and regeneration for heritage areas in the historic core of İzmir, Mezarlıkbaşı-Kemeraltı, as well as to discuss the intrinsic physical qualities, dynamic characters and diversity of community groups with a view of new spatial agenda. The objective of the study is therefore twofold: 1) documentation of the physical characteristics and values for understanding the place; 2) to evaluate incorporating integrated strategic planning and management approach pointing the need for incorporating, leadership, partnership, integration and inclusion as a policy guideline for the safeguarding the heritage area. Our findings show that the Municipality of İzmir has made a significant attempt as TARKEM’s leadership position, which has succeeded in attracting national and international interest in Kemeraltı and creating opportunities for the future, but partnership (operation), management (structure) and inclusion (its processes) still lack. Community groups are not seen as part of the planning activities and planning has been remote, fragmented and exclusively missing an integrated planning management approach. © 2021, Istanbul Teknik Universitesi, Faculty of Architecture.

    Spatial Effects of Air Transport on Regional Development : Evidence From Turkey
    (Fabrizio Serra editore, 2020) Nijkamp, Peter; Pels, Eric; Elburz, Zeynep
    The rapid rise of aviation (including airport infrastructure) has prompted various research and policy questions on its socio-economic impact on spatial development of regions. Since the aviation industry facilitates a worldwide transportation network for business and tourism, it is considered to be a critical factor for economic growth. This study aims to analyze the relationship between air transport and regional development in Turkey, by using air passenger volume and regional employment data by means of both non-spatial and spatial regression methods. We run a Two-Stage Least Squares (2SLS) regression model with instruments to capture endogeneity, and Generalized Spatial Two-Stage Least Squares (GS2SLS) models to control for the spatial context by using data from 81 Turkish NUTS 3 regions (provinces) between 2008 and 2017. We extend the existing literature by measuring spatial spillover effects of air transport on regional growth. To the best of the authors' knowledge, this study is the first attempt to examine this link by considering both spatial effects and endogeneity problems. The results confirm our hypothesis that air transportation is an important determinant of regional employment in Turkish regions while the impact of air transport on regional employment decreases when spatial effects are taken into consideration.
