Published: January 2022

With the growth of the customers and the expansion of the 4G LTE network in the area of Padang City, a PCI (Physical cell identity) modulo interference spot has been detected. PCI modulo interference occurs when an area is covered by two or more cells, which have a strong signal, and these cells have the same PCI modulo value. Based on the measurement results by the driving test method, the network conditions were not optimal because the SINR percentage (Signal to Interference Noise Ratio) in the good category was still low, at 9.47%, and the download throughput in the good category was 18.94%. This indicated that the interference in the area was quite high. Thus, it was necessary to do optimization action. The optimization action was taken by rotating the PCI on the site by considering the modulo value of each site so that the PCI with the same modulo did not merely lead to one location. Besides, action was taken to change the azimuth direction of cells that were too dominant. Based on the optimization process that has been carried out and the driving test activities that have been carried out again, the performance in the existing conditions has increased. The SINR percentage in the good category increased by 10%, so it became 19.47%, and the download throughput in the good category increased by 44.74% and became 63.68%.

Published: January 2022

SPACeMAP is a remote-sensing data portal system owned by LAPAN used to distribute mosaic data of Medium-Resolution to Very-High-Resolution for Provincial Governments. The frequently arising problem is that mosaic images have very large data size, especially for SPOT-6/7 mosaic images. The increasing number of data and users may affect the data loading process on the portal so that mosaic data compression can be considered. SPACeMAP has the Image Compressor feature using the Tile and Line algorithms with a compression ratio (target rate) recommended for optics (15 to 20). This study aims to determine the best algorithm and target rate to get compressed mosaic SPOT-6/7 imagery. The comparison method was done qualitatively through visual comparison and quantitatively by using Compression Ratio (CR), Bit per Pixel (BPP), and Peak Signal to Noise Ratio (PSNR).Â  Results of the experiment show that, quantitatively, both Tile and Line algorithms give a different performance, depends on the zoom level and land cover characteristics. In terms of the qualitative result, the Tile algorithm gives better overall results compare to the Line algorithm. Quantitatively, both algorithms show good performance in the homogenous area. The target rate difference on the testing range does not affect process duration, nevertheless, the Line algorithm has a long process duration compare to the Tile algorithm. However, compression mosaics with lower or higher resolution remote sensing data may provide different results. Hence, this need be addressed on further studies.

Authors: Sonatha Yance , Azmi Meri , Rahmayuni Indri
Published: January 2022

Cooperatives are one of the business units which purpose is to help the economy of small and medium-sized communities. One of the cooperatives in the city of Padang, West Sumatra, Indonesia is KPN Kapur Warna. The routine business unit managed by KPN Kapur Warna is for savings and loans. So far, the savings and loan process is still done manually, including determining the eligibility of members to receive loans. Determination of the eligibility of members is carried out less objectively, by only looking at the profile of participants in general and the decision-making process is only carried out by one person, namely the chairman of the cooperative. The process that has been carried out so far has often resulted in wrong targets, namely providing loans to members who are not appropriate, resulting in bad credit or delays in paying monthly installments of participants. Therefore, we need a group decision support system that can help solve the above problems. In this study, a group decision support system was made using the AHP, TOPSIS and BORDA methods using five main criteria. The AHP method is used to determine the priority value for each criterion and the TOPSIS method is used to rank each alternative. Each decision maker performs the same process with the two methods, and then voting is carried out using the BORDA method of combining assessments for different decision makers. This study succeeded in providing a reference in determining the eligibility of which members are entitled to receive loans from cooperatives, with results that are more subjective and can help cooperatives in their work efficiently.
Feature-reduction Fuzzy c-means Clustering for Basketball Players Positioning
Authors: Nataliani Yessica
Published: January 2022

One of the best-known clustering methods is the fuzzy c-means clustering algorithm, besides k-means and hierarchical clustering. Since FCM treats all data features as equally important, it may obtain a poor clustering result. To solve the problem, feature selection with feature weighting is needed. Besides feature selection by assigning feature weights, there is also feature selection by assigning feature weights and eliminating the unrelated feature(s). THE Feature-reduction FCM (FRFCM) clustering algorithm can improve the FCM clustering result by weighting the features and discarding the unrelated feature(s) during the clustering process. Basketball is one of the famous sports, both international and national. There are five players in basketball, each with a different position. A player can generally be in guard, forward, or center position. Those three general positions need different characteristics of playersâ€™ physical conditions. In this paper, FRFCM is used to select the related physical feature(s) for basketball players, consisting of height, weight, age, and body mass index. to determine the basketball playersâ€™ position. The result shows that FRFCM can be applied to determine the basketball playersâ€™ position, where the most related physical feature is the playerâ€™s height. FRFCM gets one incorrect playerâ€™s position, so the error rate is 0.0435. As a comparison, FCM gets five incorrect playerâ€™s positions, with an error rate of 0.2174. This method can help the coach decide the basketball new playerâ€™s position.

Media Cultural Landscape: Experience from Czechia
Authors: Such|ček Jan , Koutský Jaroslav
Published: January 2022

This paper investigates media reflection of the culture that is bound to self-governing regions in Czechia. The primary focus is on regionally related reports dealing with culture as they appear in the framework of the national TV coverage. Thus, the main objective of the article is to analyse, evaluate and interpret culture-related and regionally orientated contributions broadcast within the national TV reporting. Con-trary to the majority of TV reports that are negatively skewed, culture represents mainly positive themes. It is surely interesting for individual self-governing regions if their culture is presented within national TV coverage. Our paper tackles the issue from both quantitative and qualitative perspectives. This is even more exciting in view of the fact that the topic has been severely under-researched so far. The article brings geographically rather differentiated media portrayals of individual self-governing re-gions in Czechia in the sphere of culture, which can be of interest to both theory and practice.

В этой работе приставочные глаголы с за- Слова о полку Игореве классифицируются в рамках словарных статей, чтобы раскрыть их семантику и видовое значение. С целью определить их семантические и видовые свойства употребляются в качестве точки отсчета четыре типа значения (только-пространственное, пространственно-результативное, временно-результативное, только-результативное), которые в (древне-)русском приставка за- показывает в своих комплексных глаголах. Они же определяют не только значение в глагольной лемме с за-, а также образование ее видовых пар функционально (предельная, тривиальная, перфектная, пролептическая) и морфологически (произведенные заменой основы, суффиксом или депрефиксацией). Только-пространственные глаголы с за- (непарные глаголы несовершенного вида, крайне редкие в древнерусском, например, залежати (ʻлежать в осаде’) в Слове не встречаются; пространственно-результативных глаголов, несущих в своей приставке указание на совершенный вид вместе с пространственным представлением (классифицируемом в рамках трех сем BEHIND, FAR, COVER и их вариантов) и образующих предельные пары, в Слове обнаружено 10: заворочаетъ, зайде, загородите, закладаше, заступаше путь, заступи путь, заступивъ знаменiе, залетело, занесе, затче. Временно-результативные глаголы, т. е. точечные глаголы совершенного вида, указывающие на начало акта, как заговорити (ʻначать говорить’), или чрезмерность в завершении, как замучити (ʻчрезмерно мучить”), отсутствуют в Слове, что подтверждает его архаичность. Только-результативных глаголов, чья приставка считается только указателем совершенной результативности, в Слове найдено 6: затвориша, затвори, зареза, закалена образуют пары суффиксом или депрефиксацией, и забывь и запала – только суффиксом.

The Role of the Ukrainian Diaspora in Translating Lesia Ukrainka’s Works into English
Authors: Shymchyshyn Mariia
Published: January 2022

The article deals with the English translations of Lesia Ukrainka’s works. The author considers the new approaches to translation that emerged after the Cultural turn in the last part of the 20th century. In particular, the attention has been paid to the issues of migration and translation, negation of the Eurocentric ideas about translation, and translation as a constituent part for the formation of migrant’s community. Considering the chronology of the translation of Lesia Ukrainka’s works into English, it is argued that as a rule they were done by the Ukrainian diaspora and published in the periodicals, financed by the Ukrainian communities in Great Britain, the USA, and Canada. The most intensive phase of the popularization of poetess’s works in English happened to be during the middle of the last century. This could be explained by the nature of the third wave of migration, which occurred after World War II. This wave brought the highly politicized people, who tried to oppose the Soviet regime. They used literature to oppose the Soviet appropriation of the Ukrainian cultural heritage. Besides the Ukrainian diaspora have utilized the native fictional discourse to maintain the boundaries and consciousness of their collectivity.

The primary purpose of this project is to explore the potential of drone or Unmanned Aerial Vehicle (UAV) to reduce the dependence on fossil-fueled vehicles to transport the crops within the farm and from the farm to the seller. The use of drones will create lower emission of carbon dioxide and toxic gases that are usually generated by fossil-fueled vehicles. Besides, this research is also essential to reduce the health issues that currently appear from agriculture activities. The objective of this project is to determine the parameters to design a suitable drone for transportation in the agricultural sector. In addition, the design of the drone must be able to carry a maximum of 10 kg of payload, which can be analyzed by simulation and analysis. The simulation and analysis are performed by SolidWorks software. The conceptual design of the drone is proposed by following the George E. Dieter model of the design process. In addition, a simulation on the strength of the drone components and analysis on the thrust of the motor have been conducted to verify the proposed drone design concept based on the determined parameters. The cost estimation of the drone is about RM17683.65 and the overall weight is 26.823 kg. In conclusion, the drone design concept for transportation in the agricultural sector is proposed as a preliminary study for future works.

Authors: Egne Robsan M.
Published: January 2022

The contribution of education to the overall development of a nation becomes evident especially through higher education. This is because higher education is considered a key to delivering the knowledge required for ensuring sustainable development. Studies reveal a strong positive correlation between higher education participation rates and levels of development, as high levels of education are essential for designing and producing new technologies, and enhancing innovative capacities for the development of a society. While the reforms of higher education in high-income countries have received much attention, relatively little is known about the change dynamics in higher education system in developing countries. Therefore, with this research I want to contribute to a better understanding of higher education system in Africa, from the perspective of the type of pedagogy being practiced frequently and its consequences in producing competent graduates for the world of work by taking Ethiopian public higher education system as a case. To this end, data were collected from selected higher education institutions’ officials and instructors using questionnaire and interviews. The collected data were analyzed using mixed method. Findings of the study revealed that despite the offering of on-job pedagogical science trainings in the sample universities, little progress has been made in terms of applying student-centered pedagogy. Most of the instructors in the institutions still predominantly use traditional teaching methods. It is recommended that instructors in higher learning institutions should use critical pedagogy.

Developing Crisis Management System for Construction Projects in Iraq
Authors: Fadhil Ghasaq abdulsalam , Burhan Abbas M.
Published: January 2022

Construction is a complicated process that takes place in an almost uncontrollable environment. Although projects can be carefully planned in advance in principle, there is a chance that unforeseen events and crises can disrupt these plans, affecting project development. Because the initial investment expenditures in construction projects are so large, they may be quickly influenced by crises, resulting in significant financial losses. The 2014 financial crisis was one of the most prominent crises that Iraq faced, which significantly impacted various activities in general and the construction industry in particular. Despite the importance of crisis management systems, the researchers found a great lack of local studies looking at crisis management, specifically in the basic stages chosen for its development, which are before, during, and after a crisis. Therefore, an effective crisis management system has been developed consisting of 20 critical success factors with devising 59 actions that can be taken for each proposed criterion for each of the three stages of crisis.

Published: January 2022

Dry gas is considered one of the most environmentally friendly sources of energy. As a result, developing an efficient strategy for storing this gas has become essential. In this work, MOF-199 was synthesized and characterized in order to investigate the MOF-199 in dry gas adsorption using a built-in volumetric system (methane, ethane, and propane from Basrah gas company). The MOF-199 (metal organic framework) was synthesized using the solvothermal method at 373K for 24h, and then it was characterized. The dry gas adsorption on MOF-199 was studied under various conditions (adsorbent dosage, contact time, temperature, and pressure). The isothermal adsorption of the dry gas had been studied on MOF-199 using two types of models: Freundlich and Langmuir. The results of the isothermal adsorption shown corresponded to the Freundlich model with a correlation coefficient (R²) of 0.9426. Also, the rate of adsorption kinetic of the first and second-order was studied, and the results showed that the reaction rate was second-order.

Authors: Shaheed Aya kh. , Azzubaidi Riyadh Z.
Published: January 2022

This study aims to numerically simulate the flow of the salt wedge by using computational fluid dynamics, CFD. The accuracy of the numerical simulation model was assessed against published laboratory data. Twelve CFD model runs were conducted under the same laboratory conditions. The results showed that the propagation of the salt wedge is inversely proportional to the applied freshwater discharge and the bed slope of the flume.  The maximum propagation is obtained at the lowest discharge value and the minimum slope of the flume. The comparison between the published laboratory results and numerical simulation shows a good agreement. The range of the relative error varies between 0 and 16% with an average of 2% and a root mean square error of 0.18. Accordingly, the CFD software is quite valid to simulate the propagation of the salt wedge.

Authors: Hasan Maha Yousif , Kadhim Dheyaa Jasim
Published: January 2022

In this work, an efficient energy management (EEM) approach is proposed to merge IoT technology to enhance electric smart meters by working together to satisfy the best result of the electricity customer's consumption. This proposed system is called an integrated Internet of things for electrical smart meter (2IOT-ESM) architecture. The electric smart meter (ESM) is the first and most important technique used to measure the active power, current, and energy consumption for the house’s loads. At the same time, the effectiveness of this work includes equipping ESM with an additional storage capacity that ensures that the measurements are not lost in the event of a failure or sudden outage in WiFi network. Then then these measurements are sent using the internet of thing (IoT) technology to Google Firebase cloud, where the electric consumer's service center is located to store, analyze the measured data, and detect cases of energy penetration when it exceeds 53  and the cases of the electrical energy theft if any below 20  and then take the appropriate decision about it. Finally, an electric smart metering application (ESM-app) is designed and implemented to read and pull data information from the Google firebase cloud and then send the electric bill to the end consumer, and sending alert messages to the thieves and electrical power hackers to prohibit them if something wrong has detected.

Groundwater is an important water source, especially in arid and semi-arid areas. Recharge is critical to managing and analyzing groundwater resources despite estimation difficulty due to temporal and spatial change. the study aim is to estimate annual groundwater recharge for the eastern Wasit Province, Iraq. Where suffers from a surface water shortage due to the region's high elevation above Tigris River water elevation by about 60 m. It is necessary to search for alternative water sources, such as groundwater use, especially with the increased demand for water in light of the growth of oil extraction in the region, where oil extraction requires a quantity of water three times the amount of oil extracted. The result shows the annual recharge calculated using the WetSpass model for the period (2014-2019) ranged from 0 to 65.176  mm/year at a rate of 27.117 mm/year and a standard deviation of 21.498. The simulation results reveal that the WetSpass model simulates the components of the hydrological water budget correctly. For managing and planning available water resources, a better grasp of the simulation of long-term average geographical distribution around the components of the water balance is beneficial.

Aralık 2019 yılının başlarında Çin’in Vuhan kentinden bildirilen ve sonrasında dünyaya hızla yayılan COVID-19 pandemisi, günlük hayatın akışında çarpıcı etkilere neden olmuştur. Sağlık endişelerinin etkisiyle fiziksel mesafe kavramının hayata girmesi ve tam kapanma gibi süreçlerle günlük yaşam ve alışkanlıklar yeniden şekillenmeye başlamıştır. Yeniden şekillenen durumlardan biri de değişen seyahat davranışları ve kentsel hareketliliktir. Kentsel hareketliliğin azalarak hayatın mahalle ölçeğinde yaşanması ve genellikle yürüme mesafesinde ihtiyaçların karşılanması veya toplu taşımanın daha az tercih edilir olması değişiklikler arasında görülebilir. Bu süreçle birlikte dünyanın farklı kentlerinde hareketliliğin sağlıklı, güvenli ve herkes için erişilebilir olacak şekilde devam edebilmesi için kentsel mekânda ve ulaşım sistemlerinde birtakım düzenlemeler gerçekleştirilmiştir. Bu çalışmada Dünya’dan farklı örnekler incelenmiş; pandemi sürecinde kentsel hareketliliğe yönelik yapılan düzenlemeler ile ilgili literatür araştırılmış, hazırlanan raporlar ve medyada yer alan haberler derlenmiş, ayrıca alternatif ve yenilikçi ulaşım türlerinin yavaş da olsa değişmeye başlayan seyahat davranışlarındaki yerinin ortaya konulması amaçlanmıştır. Türkiye’den Ankara örneğinde irdelemenin yapıldığı çalışmada, pandemi boyunca yaşanan kriz durumunun Türkiye’deki kentler için de fırsata çevrilebilmesi hedefiyle sonuç bölümünde sürdürülebilir kentsel hareketliliğin sağlanması için yerel yönetimleri de yakından ilgilendiren öneriler sunulmuştur.

Bisikletler 21. yüzyılın ulaşım sistemini yeşil kılmak, enerji tüketimini ve karbon salınımını azaltmak, sağlıklı yaşam sürmek ve COVID 19 pandemi sürecinde sağlıklı ulaşımı destekler nitelikte olması gibi pek çok olumlu özelliğe sahip bir seyahat şekli olarak görülmektedir. Çalışmanın amacı, kent içi ulaşımına eklemlenen bisiklet yollarının entegrasyon sürecinde, planlama ve tasarım ölçeğinde alınması gereken kararların uygulanmış örnek bir proje üzerinden incelenmesi olarak belirlenmiştir. Çalışma alanı olarak Kanada-Nova Scotia Eyaleti, Halifax kenti, South Park Street bölgesi seçilmiştir. Çalışma kapsamı üç aşamalı olarak kurgulanmıştır. İlk olarak, bisiklet yolları ve bağlantı noktaları için geliştirilen tasarım biçimlerinin uygulandığı yerler ve olumlu özellikleri ele alınmıştır. İkinci aşamada Halifax belediyesinin geliştirmiş olduğu üç farklı bisiklet yolu projesinin seçimi için değerlendirme kriterlerine yer verilmiş ve Halifax belediyesi ile halkın katılımcı yönüne vurgu yapılmıştır. Üçüncü aşamada, uygulanan tasarımın kullanıcı için sağlamış olduğu olumlu ve olumsuz yönler alan çalışması yapılarak analiz edilmiştir. Çalışmanın sonunda güncel ve yurtdışında yapılan bir uygulamanın planlama ve tasarım süreci değerlendirilmiştir. Türkiye’de mevcut kent içi ulaşımına entegre edilecek bisiklet yolları oluşturmak için süreç yönetiminde kullanılabilecek temel karar önerileri sunulmuştur. Trafik sıkışıklığının büyük sorun haline geldiği günümüz büyük şehirlerinde, bisiklet kullanımının alternatif ve güvenli bir ulaşım türü olması nedeniyle konunun önemine dikkat çekilmek istenmiştir.
Covid-19 and the Transport System
Authors: KNOFLACHER Hermann
Published: January 2022

The fascinating thing about the 'finding that the measures taken to contain this pandemic in the transport system have, on the one hand, achieved in a very short time precisely those effects that qualified transport scientists have been demanding from politicians for decades and, on the other hand, the fact that it has not been possible to realize the same successes in the transport system without C19, although human lives, hygiene and health are at stake in both areas. Unfortunately, little is known about the origin of C19. In the Corona crisis, one also recognizes the importance of certain self-sufficiency, not only for medical care and equipment. The relationship between C19 and the transport system is closer than one would think. C19 is the result of the thoughtless intrusion of humans into nature, which was no longer respected in its intrinsic value, but devalued to the object of marketing. The most effective measure against car addiction is to prevent the "docking" of the car to the home and all other places of human activity. This measure has been shown to be most effective in combating viral infections. The measures to be taken are; 1. car-free settlements and sanctions, 2. speed limits and effective control, 3. technical measures to minimise the risks of the remaining car traffic.

Bu araştırmanın amacı, kapitalizmin içinde bulunduğu kriz ve çelişkilerin sonucu olarak geliştirilen yaklaşımlardan birisi olan sakin şehir hareketinin nasıl bir işleyişe sahip olduğunun ve sürdürülebilirliğinin Seferihisar örneğinde araştırılmasıdır. Araştırma problemi doğrultusunda “Sakin şehir hareketi Türkiye Seferihisar örneğinde sürdürülebilir ve alternatif bir kalkınma anlayışı sunar mı?” sorusuna yanıt aranmıştır. Araştırma, nitel ve nicel araştırma tekniklerinin bir arada kullanıldığı karma metodoloji esasına uygun olarak yürütülmüştür. Araştırma kapsamında yargısal örneklem yoluyla seçilen paydaş kuruluşlar ve yerel aktörlerden derinlemesine görüşme tekniği; oranlı tabakalı örnekleme yoluyla seçilen 332 kişiden ise yüz-yüze anket tekniği kullanılarak veri toplanmıştır. Nicel ve nitel veriler birbiriyle bütünleştirilerek, birbirini destekleyici nitelikte kullanılırken Neo-Marksist yaklaşım ışığında analiz edilmiştir. Araştırmanın sonucunda, ilçenin sakin şehir unvanını kazanmasıyla birlikte gerçekleştirilen uygulamalarla sürdürülebilir kalkınma bağlamında önemli adımların atıldığı, belediyenin hizmetlerinde artış olduğu; ancak nüfus artışıyla birlikte ilçede büyük kentlerde görülen çarpık yapılaşma, soylulaşma, pahalılığın artışı, yabancılaşma, gelir farklılıklarının artması gibi sorunların ortaya çıktığı belirlenmiştir. Sonuç olarak, incelenen örnek bağlamında ilçe iyi uygulama örnekleri sunsa da hareketin sürdürülebilirliği konusunda engeller vardır.

Kentlerde daha iyi yaşam çevrelerinin üretilmesi, şehir planlama meslek alanında fiziksel çevredeki kalite standartlarına ve bunların uygulanmasına bağlıdır. Sürdürülebilir kentsel biçim (SKB) ilkeleri ise, daha yaşanabilir kentsel çevrelerin, komşuluk ve yapı-adası ölçeğinde tasarlanmasını ve planlanmasını gündeme getirmiştir. Bu bağlamda makale, Türkiye’deki kentsel alanları SKB ilkelerine göre değerlendirmeyi ve şehir planlamanın mekân üretme pratiğine katkı yapmayı amaçlamaktadır. Akıllı büyüme ve yeni şehircilik gibi akımların doğrultusundaki LEED-ND programında kullanılan SKB ölçütlerinin uygulanabilirliği kentsel tasarım yazını ve Türkiye imar mevzuatıyla irdelenmiştir. Derişiklik/yoğunluk, erişilebilirlik, karma-arazi kullanımı, yeşil alanlar, geçirgenlik ve çeşitlilik gibi SKB ölçütlerine dair ölçüm yöntemleri geliştirildikten sonra, bunlar Bursa’nın Yıldırım ilçesinde morfolojik farklılığa sahip konut alanlarını temsilen altı mahallede seçilen birer yapı adası ve çevresinde incelenmiştir. İncelenen yapı adaları en fazla yoğunluk/derişiklik ve karma kullanım ilkelerini karşılarken, sürdürülebilir bir yoğunluğun gerektirdiği açık-yeşil alanlar, erişilebilirlik ve geçirgenliğin dengelenmesinde sorunlar bulunmuştur. Bu dengeyi en fazla sağlayan 1980’lerde kooperatif yoluyla üretilen konut alanlarıyken, kent merkeziyle iç ve dış çeperlerde yer alan eski ve yeni konut dokularında imar mevzuatından ve toplumsal süreçlerden kaynaklanan farklı sorunlara rastlanmıştır. Sonuç olarak, bu çalışma konut alanlarının sorunları ve kent içindeki konumlarını göz önünde bulundurarak, geliştirdiği SKB ilkeleriyle ilgili bazı standartlar ve tasarım ölçütleri ile imar mevzuatının iyileştirilmesine katkı sağlamaktadır.

Published: January 2022

Bu çalışma, Covid-19 pandemisi sürecinde, Diyarbakır kent planlamasına odaklanarak; neoliberal politikalarla dönüşen kent mekânını, pandemi ve gündelik yaşam arasındaki ilişkiyi ele alarak incelemeyi hedeflemektedir. Analiz çerçevesine kent mekânını ve kamusal alanları alan çalışma, Diyarbakır’ın neoliberal süreçte ekonomik ve mekânsal olarak eşitsiz geliştiği ön kabulüyle, pandemi sürecinde bireylerin sahip olduğu maddi koşulların önemine odaklanmaktadır. Bu durumun mekânsal yansıması olarak güvenlikli siteler gibi kamusal alandan belli sınırlar ve mekanizmalarla ayrılan konutlar ile gündelik yaşam pratikleri arasındaki ilişki, pandeminin sınıfsal koşullar üzerinden nasıl deneyimlendiğine dair bilgi vermektedir. Metodolojik olarak bu çalışma, tarihsel bir perspektifte kentin mekânsal örgütlenmesini ve bunun salgın süreci ile ilişkisini, kent üzerine yapılmış araştırma verilerine dayanarak argümanını oluşturmaktadır. Çalışmamız, 1999’lardan sonra imara açılan Kayapınar ilçesi ile genellikle işçi sınıfının yaşadığı, gecekondulaşma eğiliminin yoğun olduğu ve kentin en eski ilçelerinden biri olan Bağlar ilçesi arasındaki sosyo-kültürel ve mekânsal farklılaşmayı pandemi bağlamında ele alacaktır.
