Women’s health are an integral part of the health of the nation and of strategic importance for the sustainable development of society. Ensuring that a woman receives all the necessary nutrients, vitamins and minerals, both before and during pregnancy, is crucial for the health of both mother and child. Even a balanced diet has deficiency on the main vitamins by 20-30%. Deficiency of vitamins and minerals during pregnancy causes harm to the health of not only the mother but also the child, is one of the causes of premature birth, congenital malformations, violations of physical and mental development of children. The need to correct a woman’s diet and the administration of vitamin and mineral complexes is due to a deficit of necessary nutrients that occurs during pregnancy and during lactation. The objective: the purpose of the study: to reduce the frequency of obstetric and perinatal complications in women at risk, through the preventive intake of a complex of vitamins and microelements and in preconception period, during pregnancy and in the period of lactation. Materials and methods. Thus, the I group consisted of 54 women who received the proposed prophylaxis treatment, which included the use of a complex of vitamins and microelements in the preconception period, in the 1st and 2nd trimester (during gestation for 8–12 weeks, 22–26 weeks) and in the postpartum period 1 tablet per day with food potassium iodide 200 mg. The second group consisted of 50 women who used commonly recognized prophylaxis treatment, including folic acid drugs and iodine preparations. Results.

Mulberry (Morus L.) has become an important crop throughout the world due to its fruits have been industrially exploited for various commercially valuable products. Many studies on mulberry related to genetic diversity, fruit quality, and breeding programs have been carried out, but little information on mulberry rootstocks is available, especially the possibility of applying grafting to improve the fruit quality. Here, we evaluated the effects of 8 different rootstocks on the fruit quality of ‘Zijing’ mulberry. Twelve fruit quality traits were extremely different except for the fruit shape index (FSI). ‘Zijing’ on ‘Zheza 2’ had the highest fruit weight (FW) and size, as well as titratable acidity (TA), but lower levels of other compounds content except the total soluble solids content (TSS) were detected. ‘Yuesang 51’ exhibited the highest soluble sugar content (SSC), reducing sugar content (RSC), SSC/TA ratio, anthocyanin content (AC) and the lower TA. In contrast, the lowest TSS, SSC and RSC were shown in ‘Guisang 5’. Moreover, ‘Guisang 12’ exhibited the highest TSS and soluble protein content (SPC). The highest vitamin C content (VC) was observed in ‘Guisang 6’. ‘Tang 10 × Lun109’, Zhenzhubai seedlings, ‘Yuesang 11’ together with ‘Yuesang 51’ had the lowest and similar levels of TA. Most importantly, these fruit quality traits were evaluated by principal component analysis (PCA), and ‘Yuesang 51’ with good comprehensive fruit quality was screened out, followed by ‘Guisangyou 12’. Overall, these results contribute to evaluating the roles of different rootstocks on improving fruit quality of mulberry.

Soil alkalinity is a severe threat to crop production globally as it markedly retards plant growth. Different techniques are used to mitigate alkaline stress, but priming techniques are considered the most appropriate. The current study was carried out in complete randomized design (CRD) to evaluate the effect of different priming techniques on maize crop grown under different levels of alkalinity stress. The experiment was comprised of different treatments of alkalinity stress (AS) including, control, 6 dS m-1 and 12 dS m-1 and different priming techniques including control, hydro-priming (HP), osmo-priming (OP) with potassium nitrate: KNO3) and redox-priming (RP) with hydrogen peroxide (H2O2). Results indicated that alkalinity stress significantly reduced plant growth and biomass production and induced severe alterations in physiological attributes and antioxidant activities. Soil alkalinity significantly reduced the root and shoot growth and subsequent biomass production by increasing electrolyte leakage (70.60%), hydrogen peroxide (H2O2: 31.65%), malondialdehyde (MDA: 46.23%) and sodium (Na+) accumulation (22.76%) and reduction in photosynthetic pigments, relative water contents (RWC), total soluble proteins (TSP) and free amino acids, potassium (K+) accumulation. However, priming treatments significantly alleviated the alkalinity-induced toxic effects and improved plant growth. OP (KNO3) remained the top performing. It appreciably improved plant growth owing to the improved synthesis of photosynthetic pigments, better RWC (16.42%), TSP (138.28%), FAA (178.37%), and K+ accumulation (31.385) and improved antioxidant activities (APX and CAT) by favoring the Na+ exclusion and maintenance of optimum Na+/K+. In conclusion, KNO3 priming is an imperative seed priming practice to improve maize growth and biomass production under alkalinity stress.

Researches carrying evidence for various uses and bioactive principles of Agastache spp. are justifying the upscaling into cultivation of these medicinal species. But, hindrances in their cultivation exist due to the insufficient documentation of their biology under field conditions. Because productivity of these medicinal species (herba) is ensured by the combined contribution of plant agronomic traits, these are related to the feasibility of the crop and therefore, can be used as predictors for successful cultivation. The aim of this study was to evaluate comparatively four valuable Agastache species (A. mexicana, A. scrophulariifolia, A. foeniculum) and one cultivar (A. rugosa ‘After Eight’), in order to identify the favourability for cultivation in local conditions (Romania). Based on the structural indicators of plant morphology (plant height, shoot number, leaf number, leaf length and width, inflorescence length, verticillaster number and flower number), registered over the span of two years, were explored relationships and similarities as well as their implications in previsioning the phenotypic potential. The results showed that studied species acclimatized successfully and all agronomic parameters studied increased in values in the second year. The average plant height in second year (2020) was 109.8 cm and average inflorescences length 9.6 cm. Stable positive correlations between inflorescence length with plant height and shoot number were observed, while differences among species became pronounced as plants become established, evidenced by clearer distinction in the second year. Phenotypic potential in the absence of inputs enables the feasibility assessment for medicinal plants introduced for cultivation in new regions.

Powdery mildew and downy mildew are primary fungal diseases that cause significant damage in viticulture. Therefore, breeding powdery and/or downy mildew resistance is one of the priority subjects in grapevine breeding programs. This study aims to conduct early-selection by marker assisted selection (MAS) method among 869 genotypes obtained through crossbreeding ‘Alphonse Lavallee’ × ‘Regent’ cultivars using the markers (GF18-06 and GF18-08) associated with downy mildew resistance gene region Rpv3.1 to develop new grapevine cultivars resistant to downy mildew caused by Plasmopara viticola.  A total of 869 hybrid plants which were obtained after crossing ‘Alphonse Lavallee’ × ‘Regent’ in a 3-year breeding program were used in the study. The hybrid plants were scored for the resistance level based on their sporulation intensity after artificial inoculation of P. viticola. DNA samples of the hybrid plants were amplified with GF18-06 and GF18-08 markers in Polymerase Chain Reaction (PCR) for MAS. The alleles which were associated to Rpv3.1 resistance locus and the results of resistance scoring were compared, and the applicability of the markers in MAS was verified. It was determined that the GF18-08/410 bp marker can be used successfully for MAS. Gf 18-06 marker 385 bp, 390 bp and 407 bp gave false positive results in our population, respectively 8.86%, 9.02% and 37.94%. Therefore, this may limit its use for MAS.

Published: March 2022

RESUMO As alianças tornaram-se fator crítico para o desenvolvimento da inovação, contudo a falta de proximidade entre os parceiros, que vai além do aspecto geográfico, pode influenciar os resultados. Apesar desse entendimento, os estudos não avaliam a inter-relação das proximidades em alianças de inovação. Esta pesquisa busca compreender quais combinações de proximidades levam a alianças exploration e exploitation. Para perscrutar esse caminho, realizou-se um survey com 174 empresas de alta tecnologia; como método, adotou-se a Análise Qualitativa Comparativa (QCA). Os resultados encontrados destacam que, no contexto de parceiros próximos fisicamente, as alianças de exploration são dependentes de proximidade social, combinadas com proximidade cognitiva ou institucional. Já as alianças exploitation são dependentes de proximidades cognitiva e social, somada à ausência de proximidade organizacional. Tem-se como conclusão que a orientação inovadora das alianças não depende do desenvolvimento de todas as dimensões de proximidade e destaca-se, assim, a relevância dos laços sociais.
COVID-19 KÜRESEL SALGIN DÖNEMİNDE ÜCRETİN KORUNMASI
Authors: ESER Dilek
Published: March 2022

Ücret, işçinin ve ailesinin yegâne geçim kaynağıdır. Aynı zamanda, devletler için önemli bir refah göstergesi ve vergi kalemidir. Bu nedenle işçiyi, ailesini ve ekonomik anlamını korumak için ücretin mevzuat bakımından güvenceye alınması bir zorunluluktur. Bu zamana kadar gerek uluslararası anlaşmalarda gerekse ulusal mevzuatlarda ücretin korunması ile ilgili sınırlar, ayrıcalıklar ve kapsam belirlenmiştir. Ancak; 2019 yılının sonunda Çin’de başlayan, hızla dünyaya yayılan COVID-19 kısa süre sonra Dünya Sağlık Örgütü’nce küresel salgın ilan edilmesine neden olmuş ve yaşanan sosyal ve ekonomik krizler ücretin korunması ile ilgili düzenlemeleri yetersiz kılmış, konuyu yeniden gündeme getirmiştir. Bu dönemde, işletmeler kapatılmış, tedarik zincirleri aksamış, ulaşım kısıtlanmış, işsizlik ve eksik istihdam artmıştır. Özellikle ücretli toplumlarda, yaşanan bu ekonomik kriz sosyal krizlere dönüşmüştür. Bu süreçte, iş hukuku uygulamaları sorgulanır hale gelmiştir. Böylece tüm dünyada iş hukuku düzenlemeleri yeniden gözden geçirilmiş, kapsam ve hak etme koşullarında basitleştirmelere gidilmiştir. Ayrıca yeni uygulamalarla mevzuat bağlamında koruma kapsamına girmeyen işçiler de görece güvenceye alınmıştır.

Türkiye’de sürecin nasıl yönetildiği ve özellikle ücretin korunması bağlamındaki değişiklik ve düzenlemeleri incelemek, bu çalışmanın temel amacıdır. Avrupa birliği ve Uluslararası Çalışma Örgütü raporlarından diğer ülke uygulamalarını değerlendirmek ve Türkiye uygulamalarını kıyaslamak ise ikincil amaçtır. Buna göre, Türkiye’de salgın zorlayıcı sebep olarak kabul edilmiş ve kısa çalışma ödeneğinden yararlanma şartları hafifletilerek yaygınlaşması sağlanmış, işverenlere sağlanan desteklerle çalışanlara iş ve ücret güvencesi sağlanmaya çalışılmıştır. Ayrıca fesih hakkı sınırlandırılarak ahlak ve iyi niyet kurallarına aykırılık halleri hariç işten çıkarmalar yasaklanmıştır. İşverenlere işçiyi ücretsiz izne çıkarma hak ve yetkisi tanınmıştır. Ücretsiz izin süresince gelirden yoksun kalacak olan işçiye İşsizlik Sigorta Fonundan karşılanmak üzere nakdi ücret desteği imkânı getirilmiştir. Bu bağlamda Türkiye, diğer dünya ülkeleri ile benzer düzenlemelerle ücreti görece korumaya almıştır.

Azgelişmiş ve gelişmekte olan ülkelerdeki kırdan kente göç olgusu, kentsel alanlarda birçok mekansal, sosyal, ekonomik ve kültürel değişimi meydana getirmiştir. Türkiye’de 1950'li yıllarda öne çıkan gecekonduların sayıları, sonraki on yıllarda artmış ve birçok gecekondu mahallesi oluşmuştur. İzmir, söz konusu dönemde gecekondu mahallerinin yaygınlaştığı metropol kentlerden birisidir. Gecekondular başlangıçta kent merkezine yakın mahallelerde oluşturulurken, zamanla kentin dışına doğru yayılma göstermiştir. İzmir’in Buca ilçesindeki Kuruçeşme Mahallesi, iç göçlerle oluşmuş eski bir gecekondu mahallesidir. Mahallede son yıllarda, kentsel dönüşüm uygulaması adı altında yıkılan gecekondu ve eski binaların yerini yeni inşaatlar ve binalar almıştır. Bu çalışmanın amacı, metropol kentin çeperindeki eski bir gecekondu mahallesindeki dönüşüm dinamiklerini ve ortaya çıkan çelişkileri analiz etmektir. Buca, kentleşme ve gecekondulaşma sorunlarının öne çıktığı yoğun nüfuslu bir yerleşim yeri olmasına rağmen, bu konuda bilimsel çalışmalar çok sınırlıdır. Dolayısıyla bu çalışmanın literatüre önemli bir katkısının olması hedeflenmektedir. Sahadan elde edilen bulgulara dayanan betimleyici bu çalışmada; nicel ve nitel araştırma yöntemleri ve bu yöntemlerin teknikleri bir arada kullanılmıştır. Çalışma kapsamında, Kuruçeşme Mahallesi’ndeki 350 haneye yapılandırılmış soru kâğıdı uygulanmış ve 20 kişiyle de yarı yapılandırmış derinlemesine görüşmeler gerçekleştirilmiştir. Eski bir gecekondu mahallesi olan Kuruçeşme Mahallesindeki dönüşüm, konut piyasası üzerinden şekillenen ranta dayalı birikim rejiminin, kentin çeper bir yerleşiminde de yaşama geçirildiğini göstermektedir. Bu dönüşümün mekâna, nüfusa, sosyal ve ekonomik ilişkilere etkisi ve de çelişkileri, araştırmanın bulguları ışığında analiz edilmiştir.

Published: March 2022

Energy consumption in buildings has been a major concern in the present construction field and the parameters that affect its performance should be carefully studied. Building airtightness is an important contributing factor to the energy consumption of a building. The measurement of air infiltration is widely practiced in some countries of Europe and North America. However, this practice is still rare and uncommon in Bhutan. At present, traditional dwellings of Bhutan have been found to be very leaky as compared to the modern Reinforced concrete structure (RCC) buildings mainly due to construction materials and techniques. The paper consists of air infiltration test carried out by the blower door method at a residential building in Bebena, Thimphu. The test has been followed by a series of data collection and interpretation of the readings obtained on site. The result obtained was air movement of 11.9-h through the building envelope which was satisfactory as in the case of Bhutan but was found to be exceeding the international standard of 3.0-h in accordance to ISO 9972:2015. The average air movement of residential buildings in Bhutan is 11.7-h according to the energy baseline report.

Published: March 2022

The rate of diabetes is rapidly increasing worldwide. Early detection of diabetes can help prevent or delay the onset of diabetes by initiating lifestyle changes and taking appropriate preventive measures. Until now, prediabetes and type 2 diabetes have proved to be early detection problems. There is a need for easy, rapid, and accurate diagnostic tools for the early diagnosis of diabetes in this context. Machine learning algorithms can help diagnose diseases early. Numerous studies are being conducted to improve the speed, performance, reliability, and accuracy of diagnosing with these methods for a particular disease. This study aims to predict whether a patient has diabetes based on diagnostic measurements in a dataset from the National Institute of Diabetes and Digestive and Kidney Diseases. Eight different variables belonging to the patients were selected as the input variable, and it was estimated whether the patient had diabetes or not. Of the 768 records examined, 500 (65.1%) were healthy, and 268 (34.9%) had diabetes. Ten different machine learning algorithms have been applied to predict diabetic status. The most successful method was the Random Forest algorithm with 90.1% accuracy. Accuracy percentages of other algorithms are also between 89% and 81%. This study describes a highly accurate machine learning prediction tool for finding patients with diabetes. The model identified in the study may be helpful for early diabetes diagnosis.

In this study, the preliminary design of an in-flight refueling door mechanism is performed. A systematic design methodology is introduced and used in the design of the refueling door mechanism. The design is divided into two sub-functions: door opening and actuation. Nine different mechanism concepts are created for the door opening function and eight different concepts are created for the actuation function. Pugh decision matrix method is used to evaluate and select the most feasible options. Six experienced engineers scored the option set, resultantly two concepts for the door opening and three concepts for the actuation sub-function are selected. Kinematic synthesis of these concepts is performed and used to determine the upper and lower bounds during optimization. Kinematic and force analysis of the concepts are performed and utilized for the constraints and cost function calculations of the optimization algorithm. Multi-objective Genetic Algorithm optimization technique is used to optimize the parameters of the selected mechanisms. The best mechanism for each sub-function is selected and combined to reach the final design. It was shown that through optimization, the required input torque decreased approximately 20% for the door opening mechanism and the required input force decreased approximately 42% for the actuation mechanism when compared to the graphical synthesis results.

Liquid storage tanks storing liquids such as gasoline and LNG are very important structures. These structures can be damaged because of the loss of strength that may occur due to external influences. It is known that a considerable amount of damage occurred in tank structures, which are one of the industrial structures, happened during the earthquakes occurred in the past. Determining the behavior of the buildings which are under the effect of an earthquake is very important in order to prevent damage to the building during a possible earthquake. The behavior of structures built on soft soils is considerably different from that of structures constructed on a rigid soil. For this purpose, in this study, a steel tank structure was modeled by considering the different soil profiles. During modelling, an elastic spring method was used for the soil while the finite element method was used for the tank and the basic interaction of the soil and foundation structure which are exposed to earthquake loads were examined. Dynamic analyzes were carried out using the time history method by taking into consideration 11 earthquake records having the different properties. According to the results of the displacement and stress values obtained; It was observed that the values obtained in the earthquakes, whose peak ground acceleration and ground velocity are large, are higher than other earthquakes. It was seen that as the soil resistance increases, the strength of the structure increases during earthquakes.

Published: March 2022

ZnO nanosheets were fabricated on a silver-metalized polyimide (PI/Ag) substrate using electrochemical deposition. For a comparison, PI/Ag film was also obtained by electroless deposition. FE-SEM, XRD, UV–Vis absorption, and I-V measurements were employed to examine the structural, optical and electrical properties of silver-metalized PI film and ZnO deposited PI/Ag film. FE-SEM analysis indicated that a continuous silver film layer, consisted of spherical Ag nanoparticles, and the ZnO nanosheets were synthesized on PI substrate by electroless and electrochemical deposition, respectively. Moreover, the growth mechanism of the Ag film and ZnO nanosheets was also discussed. The characterization of X-ray diffraction verified that the ZnO nanosheets had a hexagonal phase and grew along the [002] direction. The optical absorbance spectra of bare PI, PI/Ag, and PI/Ag/ZnO showed a broad absorption peak around 300 nm. The electrical properties of the PI/Ag and PI/Ag/ZnO samples were studied by current-voltage (I-V) measurements in the dark environment at room temperature (300 K). The I-V measurements suggested that the samples presented ohmic characteristics. The results revealed that the deposition of ZnO on PI/Ag substrate improved the electrical conductivity compare with bare PI/Ag.

Benincasa hispida (BH) contains a range of compounds which play important roles in treating human illnesses. This study was undertaken to evaluate the hypoglycaemic and protective effects of BH fruit on diabetes mellitus (DM) rats. The dose of 250 mg/kg of B. hispida aqueous extract (BHE) is the most effective dose in decreasing blood glucose level (BGL). After eight weeks of treatment, the BGL of BHE-treated DM rats (21.4±1.0 mmol/l) was found to be significantly lower than control DM rats (30.1±3.8 mmol/l). The weight of BHE-treated rats was also higher compared to the other DM groups. Overall, the biochemical evaluation of BHE-treated rats such as lipid profile, liver function test, kidney function test and HbA1c showed an improvement in biomarker values compared to the other groups. There were enhancements in liver and kidney structures of the BHE-treated group compared to those with metformin treatment, which indicated the protective effects of BH on the impaired organ structure. These findings suggest that BHE treatment exerts hypoglycaemic and protective effects in DM by decreasing the BGL, improving weight and biochemical parameters, as well as protecting liver and kidney from serious damage.

The hexane insoluble fraction of the Garcinia dulcis (GD) flower extract comprises mainly camboginol and morelloflavone which possess potent in vivo and in vitro antioxidant properties. This study aimed to evaluate the effects of 4-week oral administration of GD flower extract on the arterial blood pressure (ABP) and the excretory function of the kidney in the 2-kidneys-1-clip (2K1C) renovascular hypertensive rats (total=12) compared to sham operated (SO) normotensive Wistar rats (total=12). Four weeks after hypertensive-induced surgery, either 50 mg/kg BW GD flower extract or vehicle was orally administered to the 2K1C or SO groups (n=6/group) daily for four weeks. ABP and the renal excretory function were studied in anesthetized rats, and expression of endothelial nitric oxide synthase (eNOS) mRNA in the isolated thoracic aorta were measured. In the 2K1C rats, GD flower extract significantly decreased ABP while increased significantly eNOS mRNA levels. GD flower extract did not exert a diuretic effect in either SO and 2K1C rats since there was no change in observed urine excretion, but it did tend to attenuated the renal tubular damage caused by renovascular hypertension. GD flower extract was anti-hypertensive in this model of renovascular hypertension and problably acts via the endothelial nitric oxide signaling pathway.
A New Set of Automated Methodologies for Estimating Site Fundamental Frequency and Its Uncertainty Using Horizontal-to-Vertical Spectral Ratio Curves
Authors: Yazdi Mohammad , Motamed Ramin , Anderson John G.
Published: March 2022

This study proposes a new set of methodologies to estimate the site fundamental frequency using the horizontal-to-vertical spectral ratio (HVSR) of recorded surface ground motions. Because of the lack of consensus in HVSR calculation among researchers, a wide range of methods are practiced in this area, yielding different site fundamental frequencies at a given site due to analyst subjectivity. In this study, current practices for combining horizontal components—geometric mean and RotD50—are examined first, and results show that both methods provide comparable HVSR curves. However, RotD50 has the advantage of being orientation independent. Second, the application of Fourier amplitude spectrum (FAS) and 5% damped pseudospectral acceleration (PSA) in computing HVSR is studied, and results are presented for one case study in which PSA-based HVSR seems to suffer from scenario dependency, whereas the FAS-based results appear stable. Different values for Konno–Ohmachi smoothing parameter b were evaluated, and its effect on estimating the site fundamental frequency was considered; using b = 40 is our preference. In previous studies, average HVSR curves were used to estimate a single number representing the site fundamental frequency without incorporating uncertainty. This study proposes four methodologies that use events’ individual HVSR curves to estimate the site fundamental frequency and its associated uncertainty in a completely automated manner. Methods 1–3 use individual HVSR curves to find the maximum-likelihood estimate of the site fundamental frequency (fml), whereas method 4 uses both individual and average HVSR curves to estimate the first resonance frequency (f0). To evaluate the automated methods, a subset of the Next Generation Attenuation-West2 dataset is used to study 50 stations, and the results are compared with an independent study demonstrating good consistency. The proposed methods are further illustrated using data from the Garner Valley Downhole Array (GVDA), which highlights the pros and cons of the presented methods.

Bu çalışma T.C. Cumhurbaşkanlığı Devlet Arşivleri Başkanlığında bulunan H.1262/M.1846 tarihli ML. VRD. CMH. d/628 Numaralı Cizye Muhasebe Defteri’nden hareketle Ayntâb’da yaşayan gayrimüslimlerin ödemiş oldukları cizye vergileri, ikamet ettikleri mahalleler, nüfusları ve yaptıkları meslekler hakkında bilgi vermektedir. Buna göre şehrin bir çok mahallesinde ve köylerinde Müslümanlarla gayrimüslimler bir arada yaşamışlardır. Bu durum şehirde gayrimüslimler ile Müslümanlar arasında dini ve sosyal bir ayrışma olmadığını göstermesi bakımından dikkat çekicidir. Ayrıca kentte dini temelli oluşmuş olan Hâyk-ı Zimmîyan ve Hâyk-ı Müslüman mahallelerinde Müslümanlar ve gayrimüslimler bir arada yaşamıştır. Nitekim bu hususlar şehirde yaşayan Yahudiler için de aynı olmuştur. Şehirde bir çok gayrimüslimin Müslüman veya Türk adı taşıması kültürel birliktelik olduğunu göstermektedir. Ayntâb’a civar kentlerden garip ve perakende gayrimüslim yahut Yahudilerden gelenlerin olması da kentte kalıcı veya geçici bir gayrimüslim nüfus artışı olduğunu göstermektedir. Ayrıca aynı mahallelerde akrabaları ile yaşayan gayrimüslimler, Yahudiler ve şehir dışından gelenler de cizye vergilerini ekonomik durumlarına göre ödemişlerdir. Ticari ve zanaatla uğraşan gayrimüslimler lonca teşkilatı içinde yer almakla birlikte bazı gayrimüslimler veya Yahudiler hekimlik ve kuyumculuk gibi elit meslekler yapmışlar ve yaptıkları meslekleri de nesilden nesile aktarmışlardır. Bu durum şehirde mesleki bir tekelleşmenin olmadığını göstermektedir.

Authors: ATAŞ Berkan
Published: March 2022

Teknolojideki gelişim finansal piyasaları da doğrudan etkilemekte ve yeni ürün ve hizmetlerin piyasalara kazandırılmasına katkı sağlamaktadır. Kripto para piyasası da gelişen teknoloji ve dijitalleşme sonucu hayatımıza giren finansal araçlardandır. Yaklaşık 2 Trilyon Dolar değeri bulunan bu piyasalar, yatırımcılar tarafından oldukça büyük ilgi görmesine rağmen hakkındaki bilgi sınırlı seviyededir. Çalışmada kripto para piyasasındaki asimetrik volatilite bulguları Covid-19 pandemisi ve öncesi baz alınarak karşılaştırmalı olarak incelenmiştir. Çalışmadaki veriler piyasa değeri olarak en büyük 4 kripto para birimini kapsamaktadır. Volatilite asimetrisinin tespiti için GJR-GARCH (1,1) modeli uygulanmıştır. Bulunan sonuçlara göre kripto para birimlerinin tamamında kriz öncesi dönemde asimetrik volatilite görülmezken kriz sonrası dönem için asimetrik volatilite özelliği göstermektedir. Tersine (zıt yönlü) asimetrik volatilite bulgusuna hem kriz öncesi hem de kriz sonrası dönemde rastlanmamıştır. Bununla birlikte kripto para piyasasında hem pandemi öncesi hem de pandemi sonrası dönemlerde büyük dalgalanmalar yaşansa da ertesinde uzun dönemli varyansa yakınsama (mean reversion) etkisinin görüldüğü tespit edilmiştir.
