Sur, Haydar; Baş, Kazım
The countries' unpreparedness in managing the COVID-19 epidemic and the inadequacies of the global health system have turned the outbreak into a worldwide health crisis. In this study, the impact of the COVID-19 health crisis on the health systems of countries was evaluated based on the literature in terms of global health systems. Unlike other epidemics, the coronavirus has spread rapidly in all countries, regardless of income. The United Nations and the World Health Organization (WHO) stated that a joint approach is necessary for supporting global solidarity policies so that the COVID-19 process due to social, economic, and health inequalities between countries does not get worse. However, it has been seen that the disagreements between some powerful countries that are influential in global politics negatively affect the global health system and epidemic management. With the onset of the COVID-19 epidemic, some countries brought the "my nation first" approach to the fore, undermining the fair implementation of global health policies. The member countries of the World Trade Organization have also violated the trade agreements made and imposed export restrictions on the products necessary for the fight against the epidemic. It has also been reported that high-income countries disregarded public health and human rights approaches during the epidemic and reached COVID-19 vaccines proportional to their purchasing power. It has been observed that the epidemic cannot be managed effectively at the global level, although the global health system is more needed throughout the world during the pandemic process. It was emphasized that redesign is necessary for effective governance of the global health system.

Ayvaz, Kartal Murat; Teker, Menekse Suzan
Sürdürülebilirlik; tekstil sektörünün hammadde temini, iplik eğirme, dokuma, örme, terbiye, boya/baskı ve konfeksiyon bileşenlerinin tüm süreçleriyle ilgili bir kavramdır. Sürdürülebilir bir yaklaşım insan sağlığı ve ekosistem açısından sentetik madde kullanımının en aza indirilmesi, hızlı tüketim anlayışından vazgeçilmesi, sınırlı ve kıt kaynakların iktisatlı kullanılmasını gerektirmektedir. Sentetik boyaların üretimi ve kullanımı sonrasında oluşan atıkların çevre ve insan sağlığı açısından yarattığı sorunlar birçok akademik çalışma ile ortaya konmuştur. Doğal boyaların bu noktada ön plana çıktığı bilinmektedir. Türkiye’de tekstil işletmelerinde doğal boya kullanımına daha gerçekçi ve çözüm odaklı yaklaşabilmek adına Türkiye’de doğal boyalı giysi ve aksesuar üretimi yapan tekstil işletmeleri incelenmiştir. İşletmelerin tekstil ve çevre konusundaki bakış açıları, ürünleri ve kullandıkları doğal boya kaynaklarına yer verilmiştir. Hammadde kaynaklarının sürdürülebilir bir yaklaşım ile değerlendirilmesi noktasında işletmelerden yalnızca bir tanesinin atık olarak değerlendirilebilecek boyarmadde kaynakları kullandığı görülmüştür. Hem mevcut uygulamalara dair hem de “doğal boyaların tekstil endüstrisinde kullanımı” problemine alandaki akademik çalışmalardan, tartışmalardan, gözlem ve deneylerden hareketle tıbbi ve aromatik bitkilerin uçucu yağı alınmış posaları ile tıp, gıda ve kozmetik sektörlerinde kullanılan bitkilerin atıklarının (posalarının) kullanımına yönelik çalışmalar derlenerek öneriler sunulmuştur.

Danabaş, Durali; Naz, Saima; Chatha, Ahmad Manan Mustafa
In fish embryos, a variety of abnormalities have been found, including stunted growth, a reduced survival rate, and aberrant development. One plausible explanation is that early embryonic stages are more sensitive. Embryonic studies provide additional information regarding the various impacts of heavy metals on fish, but information on larval abnormalities caused by waterborne metals is lacking. It is found that cadmium (Cd) causes a decrease in thyroid hormone levels as well as a disruption in fish growth hormone expression. Similarly, negative health effects have been documented as a result of nickel (Ni) exposure. Some toxic effects on organs, skin irritation, skin itches or blisters and allergic reactions may occur as a result of Ni exposure. This review study focuses on the impacts of Cd and Ni, on the embryonic development of different fish species. The evidence on abnormalities in fish larvae caused by Cd and Ni was also provided in text.

Şakar, Murat; Sarıkan, Ümran
Modern kapitalist toplumlarda spor taraftarlığı bireylerin ‘serbest zaman’ etkinliklerinin neredeyse büyük bir bölümünü oluşturmaktadır. Kendilerini bir gruba ait hissetmeleri bağlamında hem bireysel hem de toplumsal bir rolü bulunan spor taraftarlığı kavramı toplumsal bütünlüğün sağlanması adına da önemlidir. Diğer yandan spor taraftarlarının gerek sosyolojik gerek psikolojik gerekse zihinsel açıdan, kendilerine ait hissettikleri alanlar şiddet mekânlarına dönüşebilmektedir. Tam da bu nedenlerden dolayı bireyler serbest zamanlarında ötekileştirilen, ayrımcılığa maruz bırakılan sosyal bir ortamda kalabilmektedirler. Bu bilgiler doğrultusunda araştırmanın amacı ‘‘Kırık Cam Teorisi ve Sembolik Etkileşim Kuramı’’ bağlamında spor taraftarlarında şiddet olaylarını sosyolojik boyutlarıyla analiz etmek ve tribünde var olan şiddet olaylarının bireysel ve toplumsal boyutlarının incelenmesidir. Araştırma, literatürün imkân dâhilinde taranıp elde edilen verilerin birbiri ile ilişkilendirilmesi sonucunda sistematik bir derleme çalışması olarak yürütülmüştür. Tribünde yaşanan saldırganlık ve şiddet eylemlerinin anlaşılması adına Kırık Cam Teorisi, toplumsal alanda belirli bir düzensizliğin bireyler tarafından hemen fark edileceğini ve o düzensizliğe ilişkin yaptırımların olmaması hâlinde bireylerin eylemlerine devam edeceğini vurgulamaktadır. Sembolik Etkileşim Kuramı ise, bireylerin eylemleri ile birbiriyle ilişki ağı kurduğunu ve somboller aracılığıyla birbirlerini etkilediklerini ifade etmektedir. Tam da bu noktada trübünde olan herhangi bir şiddet söylemi ya da eylemini fark eden birey(ler) zihinsel olarak sistemin bir açığını bulduğunu düşünerek düzensizliğe hizmet eden davranışlar sergileyebilmekte ve bu düzensizlik boyutu diğer grupları da etkileyebilmektedir. Tüm bu nedenler zincirininin devam etmemesi için, şiddet sorunsalının boyunun belirlenebilmesi ve nedenlerinin tespit edilip çözüme kavuşturulması gerekmektedir. Araştırma, bu doğrultuda, analitik metot ve yorumsamacı yaklaşım kullanılarak yürütülmüştür. Detaylı literatür incelemesi neticesinde, elde ettiğimiz sonuçlara baktığımız zaman Kırık Cam Teorisinin sporda şiddetin kaynağına ve ne olduğuna dair yanıtlar verebildiği gözlemlenmektedir ve aynı zamanda Sembolik Etkileşim Kuramı ile birlikte ele alındığında toplumsal alanda düzen ve istikrarın sağlanmasında yardımcı olabileceği düşünülmektedir.

Yaman, Hümeyra; Sanyürek, Nesrin Karaca
Haploid plant production is of great importance to shorten the breeding period in plant breeding programs. Obtaining pure lines in plant growing programs require an intensive work with huge labor and time. Obtaining one hundred percent homozy-gous pure lines is a key point for the improvement and development of new cultivars. Haploid plants with a single set of homozygous chromosomes have become a valuable tool in plant breeding. Dihaploid plants that are homozygous at all loci with dou-bling of their chromosomes can be propagated by seed and reach full homozygosity in a single generation. Traditional methods take seven years to reach homozygosity. Dihaploidization methods provide significant advantages in terms of gaining homozy-gosity in a short period of one year and bringing pure lines into agriculture. Anther culture and irradiated pollen technique are among the most widely used techniques in this respect; where physical or chemical agents are used to induce mutated pollen grains and anthers that are subsequently employed to develop dihaploids through in vitro cultures. These techniques are a good source to facilitate gene mapping, cyto-genetic research, and evolutionary studies. Irradiated pollen culture techniques have been applied to many oilseed crops to obtain pure lines. This study highlights some salient features of producing dihaploids using irradiated pollen grains and their maintenance.

The safety of underground energy transmission pipeline network is threatened by traffic, earthquakes, explosions, and other stresses. To solve the problem of damage to the underground energy transmission pipeline networks by external loads, this study analyzed the mechanical properties of the Pipe-Soil Coupling System (PSCS) under external loads from a mechanical perspective. The pipeline constitutive model, the soil constitutive model, the internal effect of the PSCS, the influence of external stresses on the PSCS, and the dynamic response of the PSCS under various research methodologies were all studied. First, different mechanical features of the pipes and soil were employed to investigate the pipe and soil constitutive models. Second, based on the different force directions within the PSCS, the earth pressure and axial friction of the PSCS were investigated to clarify the interaction between the pipe and soil. For the purpose of to better understand the degradation of the underground pipeline state, the impacts of man-made and natural stresses on the PSCS failure were explored. Finally, the results of the investigation of the dynamic response of the PSCS were examined for their applicability using three research methods: theoretical analysis, numerical simulation, and experimental analysis. It is found that the existing constitutive models of pipeline and soil are lack of basis, which increases the difficulty of the selection of constitutive models in the process of research. In the analysis of load effect, earth pressure plays a dominant role in affecting the local stability of pipeline, but the calculation accuracy of soil pressure needs to be improved. Due to the lack of experimental guidance for complex damage phenomena under external loads, it is impossible to accurately determine the limit state parameters of pipelines under complex damage modes. It is critical to create and refine the theory underpinned by numerous experimental data in order to address the issue of pipeline dynamic response under multi-field coupling, including explosion and earthquake. This work is critical for analyzing existing research findings, identifying future research problems, and enhancing buried pipeline safety management.

Turgut, Yiğit Emrah; Aslan, Alper; Kopuz, Tuba
The use of the Internet and social media has increasingly become widespread. Social media has become an important part of daily life. Thanks to social media, people can receive and offer services in many fields such as education, entertainment, and trade. Social media which is effective in the daily life of many people from different walk of life has also reflected in parents’ routines. The purpose of the current study is to define the concept of sharenting within the framework of the literature and explain the development process of the concept, express the reasons for the parents’ sharenting behaviour, address the problems created by the sharenting behaviour, and examine the sharenting behaviour within the framework of national and international legal regulations. Sharenting refers to sharing content about children by parents in digital media. The concept of sharenting in English emerges from the combination of the terms “sharing” and “parenting”. Along with studies on the concept of sharenting start- ed in 2012, the first academic study was conducted in 2015. The first study on the concept of sharenting in Turkey was carried out in 2016. “Sharenting” is a new, current, and popular concept in both international and national literature. Although the concept can be translated into Turkish as “paylaşan ebeveynlik”, there is no corresponding translation of the concept in Turk- ish as widely accepted. However, having a Turkish equivalent for the concept can be effective in raising and creating awareness of this behaviour in people. Therefore, one of the ways that many parts of the society, especially parents, can internalize the related concept expressively is to create a Turkish expression for the concept. It can be recommended for language experts and academicians working in the field of language education and teaching to find or create a response to the related concept that society can adopt. Besides, the Turkish Language Association (TDK) can also carry out studies on this subject. Today’s parents who have adopted the use of social media use social media for different purposes such as discussing their parenthood, finding solutions to parenting issues and giving advice to other parents, providing social interaction. Shar- enting is effective in fulfilling some of the needs of parents. In fact, parents can fulfil some of their learning needs with sharing. It also provides parents with social interaction and communication opportunities with other parents. Besides, sharenting is also effective in fulfilling some affective needs such as the acceptance of parental identity and appreciation of parenting practices. Thus, sharenting is an activity which offers opportunities to parents. However, when parents share by using their parental identities, they also include their children. Parents think that there is not any situation in which their children are exposed to harmful effects while sharing. However, every share on social media about children exposes them to some digital risks. Even the disclosure of parents’ identity through children may trigger ethical problems. The ignorance of the possible consequences of the sharenting behaviour on children is the reason for the uncon- scious violation of the privacy of children by the parents. The problem with sharenting is that parents configure their children’s digital identities without their children’s consent. Indeed, children’s digital identities should be created by themselves, not by their parents. The reason is that children are individuals who have the capacity to have rights. Therefore, this situation causes a violation of personal rights. The children’s satisfaction with their parent’s share is also unknown. As a result, it is foreseen that parents will have to encounter some legal processes in the future. Hence, the fact that the defendant-complainant re- lationship will be a parent-child relationship should be known. However, when considering the cultural structure of Turkey, it is predicted that the children’s complaints against their parents will be lower than in Western culture. However, regardless of the situation, national and international legislation and legislative regulations are in favor of the children’s interests. Social media platforms can be sensitive to prevent the parent-child conflicts arising from the sharenting behaviour and as a precau- tion they can provide a kind of warning before sharing. In the content shared, the user can be notified before sharing by using the face and word recognition systems. It is possible that shares in a way that does not risk the children’s safety, personality and existence as an individual are reasonable. However, there is no well-accepted criterion describing the ‘reasonable’ level. Although there is no regulation on what information parents can share about their children in many countries, it is considered that it is not possible to find a global solution. However, non-governmental organizations such as the Family Online Safety Institute can develop a common approach to the relevant situation and can ensure that the reasonable sharenting level is determined. The developed ap- proach can also be used as a government policy regarding the sharenting behaviour. Initiatives to determine the reasonable level can be supported by extensive research such as the European Children Online Project (EU Kids Online) including Turkey and other 24 European countries and Global Kids Online supported by UNICEF.

For life to exist on earth, there must be water. Freshwater resources are in short supply due to industrialization and the world's rapid population expansion. Growing water shortage argues that using passive solar stills is the best and most practical solution in the world's arid and semi-arid regions. For applications in distant or rural coastal areas, floating solar stills are an appropriate technique. To provide accessibility to a wider population, the gadget should be constructed using inexpensive materials that are easily accessible nearby. However, the low-cost materials typically do not have the optimum physical characteristics, which reduces the overall performance of solar stills. This study intends to deliver a comprehensive review that summarizes recent research developments and gives a rundown of experimental, numerical, and experimental and numerical studies on floating solar stills and floating solar-driven membranes. This article also looks at a few more setups, researched parameters, and result-finding issues. Research on floating solar is currently ongoing, and recommendations for further research projects have been made in light of the study's findings.

Fresh water is scarce, making it a worldwide issue. In order to address global freshwater demand, a filtration technique is needed. Solar distillation (SD) that purifies brackish and sub-terranean water has been proven to be a promising green technology. It produces distilled water which can be used as potable water for drinking and other purposes. The designs, operations, and configurations of several inverted solar stills are thoroughly examined in this article. All techniques for solar water distillation to separate saltwater from freshwater have the same fundamental idea. It has been demonstrated that for a specified mass of water in the top basin, the daily output of an inverted absorber double-basin solar still (IASS) grows with increasing water depth in the bottom basin. Nevertheless, as the water depth in the bottom basin rises from 1 cm to 5 cm, the output of an inverted absorber double-basin solar system falls by about 27%. At water depths of 4, 6, and 8 cm, the daily yields from inverted absorber solar stills paired with a refrigeration cycle (RIASS) were 6.4, 10.08, and 9.5 L/day, respectively. The results also showed a substantial rise in water temperature in the inverted absorber solar still as a result of lower bottom heat loss and larger absorptivity. In this study, the emphasis on energy, efficiency, and environmental concerns remains with the modified multi-wick basin-type inverted absorber solar panel. The performance of the inverted trickling solar still was assessed with a 60 ppm average salinity under various sun radiation, feed water flow rate, and existence conditions for natural convection. It was found that the still could produce 2.55 L/day m2 of fresh water, a 15% increase. Brackish water with a salinity of 6000 ppm was used to test the still in November at tilt angles of 47◦ and 32◦ . Condensate production at the specified angles was 2.8 and 2 L/d, respectively. A total output of 6.907, 5.681, and 4.650 kg/m2 /day was also generated using the modified multi-wick basin-type inverted absorber solar still (MMWBIASS) at water depths of 1, 2, and 3 cm, respectively. With black cotton wicks, the MMWBIASS had a total thermal efficiency of 34.04%, 28.17%, and 23.61%.

Aktağ, Işıl Gürsul; Hamzalıoğlu, Aytül; Kocadağlı, Tolgahan; Gökmen, Vural
The amount of acrylamide in asparagine rich thermally processed foods has been broadly monitored over the past two decades. Acrylamide exposure can be estimated by using the concentration of acrylamide found in foods and alternatively, biomarkers of exposure are correlated. A better estimation of dietary acrylamide exposure is crucial for a proper food safety assessment, regulations, and public health research. This review addresses the importance of the presence of neglected Maillard reaction intermediates found in foods, that may convert into acrylamide during digestion and the fate of acrylamide in the gastrointestinal tract as a reactive compound. Therefore, it is questioned in this review whether acrylamide concentration in ingested foods is directly correlated with the dietary exposure to acrylamide.

Karacahan, Mehmet Kayra
The demand for rare earth elements in the world is increasing rapidly, but the supply amounts of these elements are decreasing due to export quotas imposed by the Chinese government and illegal mining operations. Many countries have accelerated their efforts to obtain rare earth elements from primary and secondary sources in order to meet their future needs by taking measures. Rare earth elements are the most important components necessary both for the design and development of high-tech products that we use in our daily lives and for the advancement of modern industry. These elements, which have become indispensable materials of our lives, are generally not found in pure form in nature, but in complex structures in ores. Rare earth elements have close to 250 known minerals, but ores such as bastnasite, monazite and xenotime are commercially exploited. It is usually physically enriched by flotation, gravity, electrostatic or magnetic separation processes to obtain bastnasite, monazite and xenotime concentrates. In order to develop viable and environmentally friendly processes, studies are carried out for the extraction of rare earth elements from leaching solutions (chloride, nitrate, sulfate, thiocyanate, etc.) and the use of different cationic, anionic and neutral extractants depending on the solution medium. Commercial extraction of rare earth elements D2EHPA, Cyanex 272, PC-88A, Versatic 10, TBP, Aliquat 336 etc. carried out using different extractants. In this work, hydrometallurgical methods used for the recovery of rare earth elements from primary sources are examined. These methods are hydrometallurgical methods consisting of leaching with acids and alkalis followed by processes such as solvent extraction, ion exchange or precipitation and reduction. With the application of hydrometallurgical processes, processes that may be beneficial for the recovery of rare earth elements under various conditions have been evaluated.

Ayhan, Nagihan Karaaslan; İpek, Yeliz
In this review, general information has been given about the recent studies on thin film coating techniques, zinc oxide (ZnO) thin films and zinc oxide films doped with rare earth elements (REE). As a thin film coating method, the sol‒gel method is widely used due to its economical nature. However, it has been seen that the magnteron sputter technique is also very popular due to its ease of application. Zinc oxide is a semiconductor with a wide band gap and is easy to produce and to supply. In addition, it does not have negative effects on the environment and human health. All these properties have led to intensive studies on zinc oxide. Due to its optical and electrical properties, it has found many different uses such as solar cells, light emitting diodes, gas sensors and flat panel displays. Recently, various studies have been carried out to improve the properties of zinc oxide and to create new areas of use by doping with rare earth elements.
