Item Transience and the Modern Turkish Interior(2023) Hasirci, Deniz; Ultav, Zeynep Tuna; Sumnu, Umut; AAC-5579-2020Despite the expansion of research in modern interiors around the world and a more inclusive dialogue with regards to geography, ultimately, the field is still lacking theory and methods derived from its own specific needs rather than being adapted from architectural research, and a focus on its transient nature that is likely to lead to more impactful research and preservation results. Modern Turkish interiors research have also expanded greatly with individual, as well as projects or research groups like docomomo_tr interiors and DATUMM (Documenting and Archiving Modern Turkish Furniture) that create awareness through various forms of scholarly (documentaries, archival work) and popular (public exhibitions, popular books and magazines, newspaper pieces, and films) interiors research and several struggles are common worldwide, socio-cultural and economic reasons result in a faster pace in Turkey, creating an urgency to implement innovative methods and approaches fitting contemporary prerequisites of the field.Item Effect of the COVID-19 Pandemic on Anxiety in Patients with Masticatory Muscle Pain(2023) Arifagaoglu, Ozge; Secgin, Cansu Koseoglu; Yuzugullu, Bulem; 0000-0001-9816-2486; 34702584; GRR-7726-2022Statement of problem. Although psychological disorders have been established as one of the etiological factors for temporomandibular disorders, anxiety levels in individuals with masticatory muscle pain before and during the coronavirus 2019 (COVID-19) pandemic have not previously been compared.Purpose. The purpose of this clinical study was to evaluate anxiety levels in patients with masticatory muscle pain at times before and during the COVID-19 pandemic.Material and methods. Eighty patients (18 to 68 years) with masticatory muscle pain were included in the study. All participants had completed the Generalized Anxiety Disorder 7 questionnaire (GAD-7) before the first COVID-19 infection had been reported in Turkey. After the onset of the COVID-19 pandemic, all participants were contacted by telephone to repeat the GAD-7 to evaluate changes in their psychology during the first lockdown. However, 18 of the 80 patients were unreachable. A statistical analysis was performed by using the Mann-Whitney U test. Proportion comparisons between sociodemographic characteristics and GAD-7 levels were performed by using the Fisher exact test (a=.05).Results. Forty-eight (60%) of the study population were women, and 32 (40%) were men, with a mean age & PLUSMN;standard deviation of 36.63 & PLUSMN;13.85 years. Both before and during the pandemic, GAD-7 scores were statistically similar as was each demographic parameter, including sex, educational status, and occupational status (P>.05). Also, no significant correlation was recorded between age and GAD-7 global scores obtained before and during the pandemic (r=-0.098 and r=-0.052, respectively, P>.05). However, during-pandemic GAD-7 scores were statistically higher than before-pandemic GAD-7 scores (P<.001).Conclusions. Demographic parameters had no connection with anxiety levels in patients with masticatory muscle pain before and during the COVID-19 pandemic. However, the COVID-19 pandemic anxiety levels in the participants were higher than the levels before the pandemic.

Power is a difficult concept to define but it is usually explained with the ability to influence. Social psychologists John French and Bertram Raven's studies have defined five bases for social influence: coercive (based on punishment), referent (based on affection), reward (based on reward), expert (based on expertise) and legitimate (based on agreed regulations) powers. Many other studies have tested their theory in various fields, and it proved to be a lasting one. Researchers conducted studies in areas such as education, business, sports with this theory and obtained meaningful results. However, the power bases of video game players has never been studied, despite the fact that video game studies has already been established as an academic field -with many scholars discussing empowerment through games. This study focuses on measuring the power of a player over another one. There can be two types of such relations: it can either take place among players in an everybody-for-themselves kind of environment - which is called inter-power relations, or it can take place between the members of a team, working together for a common goal. This is called intra power relations. This study demonstrates that expert and reward powers are preferred in inter and intra-power relations, referent being another valid option for teamwork.Item Innovations in Cervical Cancer Treatment-There is Still Room for Improvement(2023) Onal, Cem; Yavas, Guler; HOC-5611-2023; AAE-2822-2020Item Factors Determining Consumer Concerns About Clothing Industry Problems(2023) Erol boyaci, Gulay; Senturk ozer, Leyla; HOC-6390-2023Although the public concern towards unsustainable current production and consumption is growing, the inadequacy of global regulations on sustainability issues puts the responsibility on consumers. However, despite their concerns, some consumers need help shopping from sustainable brands. The current research examines some antecedents of consumer concern towards the clothing industry's environmental and sweatshop issues. Data is obtained from 372 Turkish fast fashion consumers through online platforms. Level of exposure to informative posts on social media platforms, the perceived knowledge and belief towards the issues positively affect concern. Also, decreasing concern towards these problems with advancing age is observed in Turkiye.Item Intelligent Optimization Under the Makespan Constraint: Rapid Evaluation Mechanisms Based on the Critical Machine for the Distributed Flowshop Group Scheduling Problem(2023) Wang, Yuhang; Han, Yuyan; Wang, Yuting; Tasgetiren, M. Fatih; Li, Junqing; Gao, KaizhouIn the flowshop scheduling literature, the insertion-based neighborhood search method is often considered to obtain high-quality solutions. It will lead to expending extensive computational effort when evaluating the objective function. Rapid evaluation methods based on Taillard's acceleration can reduce the time complexity of function evaluation. However, existing rapid evaluation methods cannot be applied directly to the distributed flowshop group scheduling problem (DFGSP), especially to minimize the total tardiness time objective. Thus, we first proposed two theorems and their proofs based on the critical machine. Then, two rapid evaluation methods based on these theorems are proposed to accelerate the evaluation of the objective. Considering the multiple coupled sub-problems in the DFGSP, we proposed a cooperative iterated greedy algorithm (CIG) combining two rapid evaluation methods, in which intergroup and intra-group neighborhood search strategies are proposed to enhance the search depth and breadth. Comprehensive statistical experiments show that computational effort is extensively decreased in the calculation of total tardiness time, and the CIG algorithm significantly outperforms the eight compared algorithms.& COPY; 2023 Elsevier B.V.

Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.Material and MethodIn this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined.ResultsOf the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024).ConclusionTimely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score.Item The Influence of Different Sugammadex Doses on Neural Tube Development in Early-Stage Chick Embryos(2023) Ayhan, Asude; Efe, Ekin; Fidan, Pinar A.; Efe, Oguzhan E.; Ates, Eylem Gul; Sahinturk, Fikret; Ayhan, Selim; 0000-0002-6166-2601; 0000-0001-6955-9839; 0000-0002-3243-7843; 0000-0003-3047-0305; 0000-0002-0471-3177; 37565787; HGE-9282-2022; AAJ-2057-2021; AAJ-4728-2021; W-7908-2019; ABG-5365-2020; AAI-7972-2021Background: Sugammadex is a modified gamma-cyclodextrin that has been developed with the goal of reversing the steroidal neuromuscular blocking agents. The aim of the present study is to investigate the effects of different sugammadex doses on embryologic and neural tube development in an early-stage chick embryo model. Methods: A total of 100 specific pathogen-free, fertilized domestic chicken eggs were randomly divided into five groups (n = 20, each), and placed in an automatic cycle incubator. The eggs in the "control (C)" group were incubated without administration of any drug till the end of the experiment. Subblastodermic administration of 0.9% NaCl as vehicle control (VC) and different doses of sugammadex solutions prepared with the latter [2 mg/mL (LD), 4 mg/mL (MD), 16 mg/mL (HD)] were performed at 30 hr of incubation. All embryos were removed from the eggs at 72 hr when they were expected to reach Hamburger-Hamilton (HH) stages 19-20, then they were fixed, and evaluated histo-morphologically. Results: Embryonic development was not observed in 11 eggs (1 in C, 1 in VC; 3 in LD, 3 in MD, and 3 in HD). All the developed embryos were compatible with the HH stages 19-20. A neural tube closure defect was detected in one embryo in the HD group. No statistically significant difference was found between the groups in terms of embryonic and neural tube developments. Conclusions: No significant association was found between the drug and adverse outcomes; however, a trend with dosing was seen. Further studies are required before conclude on safety and extrapolate these results to human beings.Item Comment on: Intensity Modulated Radiotherapy in Head and Neck Cancer: Initial Experience of the First Treated Cases from North-East India(2023) Topkan, Erkan; Somay, Efsun; Selek, Ugur; 0000-0001-8251-6913; 38187854; AAG-2213-2021; O-5474-2014Item Pulmonary Embolism as the First Sign of Hepatocellular Carcinoma in A Patient Who Was Cured After Five Years(2023) Esendagli, Dorina; Rahatli, Samed; Hekimoglu, Koray; Bozbas, Serife Savas; AAJ-3047-2021Pulmonary embolism (PE) is a preventable cause of death associated with high morbidity and mortality rates. Cancer is a significant risk factor for PE. In this case report, we present a patient with PE who was diagnosed with hepatocellular carcinoma (HCC) one month later. The patient had an unresectable tumor in the liver that had invaded both the inferior vena cava and the right atrium. He underwent transarterial chemoembolization (TACE) and sorafenib treatment. After two years, he underwent stereotactic radiosurgery, and he was switched to regorafenib. After five years, he was cured. This case is unique in terms of long survival compared to the literature.
