(AMER CHEMICAL SOC, 1155 16TH ST, NW, WASHINGTON, DC 20036, 2025) Şensu, Eda; Koku, Harun; Demircan, Evren; Şişman, Sebahat; Gülseren, İbrahim; Karaduman, Tuğçe; Çakır, Bilal; Okudan, Emine Şükran; Duruksu, Gökhan; Özçelik, Beraat; Yücetepe, Aysun
Angiotensin-converting enzyme inhibitory peptides derived from natural sources may be effective in the treatment of hypertension without causing side effects compared with existing angiotensin-converting enzyme (ACE) inhibitors. Naturally derived antihypertensive peptides are therefore considered a promising alternative for the prevention or treatment of hypertension. Therefore, the study aimed to purify and identify ACEinhibitory peptides from the green macroalgae Ulva rigida. In addition, the encapsulation of the purified peptides showed the highest ACE-inhibitory activity by chitosan-coated nanoliposomes, and the characterization of nanoliposomes was evaluated. Protein hydrolysates were obtained from U. rigida through enzymatic hydrolysis. The hydrolysates were separated into molecular weights of <3, <5, and <10 kDa through ultrafiltration membrane separation (UFMS). The <3 kDa fraction (UFMS-3) that exhibited the highest ACE-inhibitory activity (77.02%, 1 mg/mL) was purified using ion-exchange chromatography. Fraction-1 (IEC-F1) obtained from the ion-exchange purification showed an impressive 82.03% ACE-inhibitory activity. Moreover, peptide sequences of IEC-F1 were identified by LC-MS/MS, and their bioactive properties were determined in silico. After that, IEC-F1, with a strong ACEinhibitory activity, was loaded into chitosan-coated nanoliposomes to improve their stability for encapsulation. Physical stability (ζpotential, polydispersity index, particle size), thermal (DSC) and morphological properties (SEM), and FT-IR analyses were carried out for the characterization of nanoliposomes. Encapsulation efficiency was found to be 92.0 ± 4.5%. After encapsulation, the ACEinhibitory activity of IEC-F1 was protected by 37.5%. Overall, the obtained findings indicate that the hydrolysate produced by the successive hydrolysis of U. rigida macroalgae with pepsin and trypsin contains peptides with strong ACE-inhibitory action. Furthermore, the chitosan-coated nanoliposome method was determined to be an effective carrier for the delivery of peptide fractions, showing ACE-inhibitory activity. The formulation of chitosan-coated nanoliposomes for peptide fractions from U. rigida represents an innovative approach that allows the development of functional and stable products.

The Properties of Pectin Extracted from the Residues of Vinegar-Fermented Apple and Apple Pomace
(MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2024) Muslu Can, Aslı; Metin Yıldırım, Ruşen; Karadağ, Ayşe
In this study, both apple slices and apple pomace, the by-product of apple juice processing, were subjected to vinegar fermentation. The pectins extracted from the solid residue of vinegarfermented apple slices (FAP) and apple pomaces (FAPP) were compared to the pectin extracted from non-fermented apple pomace (AP). All samples were classified as high-methoxyl pectins, and vinegar fermentation increased pectin extraction yield. FAP, which has a lower degree of methylation, also exhibited lower thermal stability. The changes in the pectin structure were dependent on both fermentation and the state of the raw material used to produce the vinegar. Compared to AP, the proportion of homogalacturonans (HGs) increased, and the proportion of rhamnogalacturonan I (RG-I) decreased in FAP, providing higher linearity, whereas in FAPP, the RG-I region became more dominant with reduced linearity. The molecular weight distribution of samples showed that pectin from vinegar-fermented sources changed the average molecular weights and mass fraction ratios of two peaks (1255 and 340 kDa) eluted from AP. In FAP, the mass fraction of the first peak (1294 kDa) increased from 35 to 89%, whereas in FAPP, the mass fraction of the second peak (478 kDa) increased to 91%. FAPP showed greater viscosity and a more noticeable shear-thinning behavior. G′ and G′′ in FAPP were also higher than those of AP and FAP at the same concentrations (5%, 7%, and 10% w/v). This study found that applying vinegar fermentation to apple slices and apple pomaces altered the structural and rheological properties of the extracted pectins. FAP and FAPP could be suitable food additives when certain properties are required.
The Nexuses between Community Attachment, Tourism Support, and Cultural Heritage Protection in the Bektashi Faith Destination: The Roles of Perceived Tourism Impacts and Residency Length
(ISTANBUL UNIV, METHODOLOGY & SOCIOLOGY RESEARCH CENTER, CENTRAL CAMPUS, ISTANBUL 34452, Turkiye, 2024) Çifçi, Hanife; Boz, Şenay; Demirkol, Şehnaz
This study examines the nexus between community attachment (CA), residents’ perceived positive tourism impacts (POSI), residents’ perceived negative tourism impacts (NEGA), and their attitudes toward support for tourism development (SUPT) and protection of cultural heritage (SUPCH) in the Bektashi faith destination with the moderating role of length of residency. Using a quantitative research approach through the questionnaire technique, 245 eligible questionnaires were analyzed by partial least squares structural equation modeling (PLS-SEM). Findings confirmed the positive relationships among CA, SUPT, and SUPCH. However, only SUPCH positively mediated the relationship between CA and SUPT. Finally, length of residency (LOR) significantly moderated some relationships (i.e., CA and SUPCH; CA and POSI, NEGA and SUPT; and SUPCH and SUPT. Theoretically, this research concluded that CA and LOR are essential determinants of residents’ SUPT and SUPCH. Practically, policymakers and practitioners of faith destinations can develop strategies and take practical future actions.

(Istanbul Univ, Sch Business, 2023) Bicici, Demet Ozcan; Ozcelik, Ayse Oya
Most employees in Turkey have become familiar with teleworking during the pandemic. This study aims to find the Turkish employees' motivation and commitment levels regarding their intention to telework after the pandemic. The mixed method of research with an exploratory sequential strategy with QUAL -> QUAN design was used to explore and explain the motivation and commitment factors regarding the intention to telework after the pandemic in Turkey and to develop a scale. Grounded theory, exploratory factor analysis, one-way ANOVA, and independent samples t-tests were used. The results indicated that age groups affected the motivation and commitment and extrinsic motivation regarding the intention to telework after the pandemic, and education levels affected the general motivation and commitment and intrinsic motivation. As education and teleworking experience levels increased, motivation and commitment and intrinsic motivation regarding the intention to telework after the pandemic increased. Motivation and commitment and intrinsic motivation levels of the employees of companies applying teleworking systematically were higher than the employees who teleworked compulsorily during the pandemic without an adaptation process. Women's extrinsic motivation regarding the intention to telework after the pandemic was higher than men's. The motivation and commitment levels of teleworkers were significantly higher than those of non-teleworkers. The data strongly suggested that childless participants had significantly higher motivation and commitment and intrinsic motivation regarding the intention to telework after the pandemic compared to the parent participants.

(AMER CHEMICAL SOC, 1155 16TH ST, NW, WASHINGTON, DC 20036, 2023) Şensu, Eda; Ayar, Eda Nur; Okudan, Emine Şükran; Özçelik, Beraat; Yücetepe, Aysun
Macroalgal proteins were extracted from Ulva rigida (URPE) (green), Padina pavonica (PPPE) (brown), and Laurencia obtusa (LOPE) (red) using ultrasound-assisted enzymatic extraction, which is one of the green extraction technologies. Techno-functional, characteristic, and digestibility properties, and biological activities including antioxidant (AOA) and angiotensin-I converting enzyme (ACE-I) inhibitory activities were also investigated. According to the results, the extraction yield (EY) (94.74%) was detected in the extraction of L. obtusa, followed by U. rigida and P. pavonica. PPPE showed the highest ACE-I inhibitory activity before in vitro digestion. In contrast to PPPE, LOPE (20.90 ± 0.00%) and URPE (20.20 ± 0.00%) showed higher ACE-I inhibitory activity after in vitro digestion. The highest total phenolic content (TPC) (77.86 ± 1.00 mg GAE/g) was determined in LOPE. On the other hand, the highest AOACUPRAC (74.69 ± 1.78 mg TE/g) and AOAABTS (251.29 ± 5.0 mg TE/g) were detected in PPPE. After in vitro digestion, LOPE had the highest TPC (22.11 ± 2.18 mg GAE/g), AOACUPRAC (8.41 ± 0.06 mg TE/g), and AOAABTS (88.32 ± 0.65 mg TE/g) (p < 0.05). In vitro protein digestibility of three macroalgal protein extracts ranged from 84.35 ± 2.01% to 94.09 ± 0.00% (p < 0.05). Three macroalgae showed high oil holding capacity (OHC), especially PPPE (410.13 ± 16.37%) (p < 0.05), but they showed minimum foaming and emulsifying properties. The quality of the extracted macroalgal proteins was assessed using FTIR, SDSPAGE, and DSC analyses. According to our findings, the method applied for macroalgal protein extraction could have a potential the promise of ultrasonication application as an environmentally friendly technology for food industry. Moreover, URPE, PPPE, and LOPE from sustainable sources may be attractive in terms of nourishment for people because of their digestibility, antioxidant properties, and ACE-I inhibitory activities.

Use of artificial neural networks in architecture: determining the architectural style of a building with a convolutional neural networks
(SPRINGER LONDON LTD236 GRAYS INN RD, 6TH FLOOR, LONDON WC1X 8HL, ENGLAND, 2024) Cantemir, Ece; Kandemir, Özlem
The discussion of ‘‘can machines think?’’ which started with the invention of the modern computer, brought along the question of ‘‘can machines design?’’ by researchers in the design field. These developments in information technologies have also affected the architecture. Artificial intelligence applications are encountered in many areas such as pricing estimation, energy conservation security systems of buildings, ventilation systems, user-oriented interactive design solutions, computer-aided programs used in the plan production phase and design process. When the literature on artificial intelligence applications in the architecture is reviewed, it can be seen that it generally includes shape grammars, graph theory, decision trees, constraint-based models, machine learning methods, RNN (Recursive Neural Networks), CNN (Convolutional Neural Network) and GAN (Generative Adversarial Network) algorithms. In this study, the use of artificial intelligence algorithms in architecture was examined, and an example was designed to determine the architectural structures of different periods by using CNN (Convolutional Neural Network). In the study, the open source TensorFlow library developed by Google and the Python programming language were used. Employing a statistical approach and utilizing convolutional neural networks (CNNs), a study has successfully classified the current flow patterns of buildings based on datasets comprising facades of Gothic, Modern, and Deconstructivist architectural styles. The findings demonstrate the efficacy of CNNs in accurately distinguishing the intricate details of diverse architectural styles. Recognizing elements from different periods using the CNN algorithm can examine not only individual buildings but also the relationship of buildings with their environments. It can also gain an important place in the field of conservation of the architectural discipline. The historical processes, aesthetic features and changes of protected buildings can be learned with the CNN algorithm and can guide restoration decisions. As a result of the study, the employed CNN-based model can correctly classify structures with 84.66% accuracy rate.
Characterization of chemical, molecular, thermal and rheological properties of medlar pectin extracted at optimum conditions as determined by BoxBehnken and ANFIS models
(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2019) Al-Amoudi, Rami H.; Taylan, Osman; Kutlu, Gözde; Muslu Can, Aslı; Sağdıç, Osman; Dertli, Enes; Yılmaz, Mustafa Tahsin
In this work, response surface methodology and adaptive neuro-fuzzy inference system approaches were used to predict and model effect of extraction conditions of pectin from medlar fruit (Mespilus germanica L.). The pectin extracted at optimized conditions (89 °C, 4.83 h and 4.2 pH) could be classified as high methoxyl pectin. Sugar composition analysis showed that pectin was mainly composed of D-galacturonic acid, L-arabinose, L-rhamnose, D-galactose and D-glucose. Fourier Transform Infrared Spectroscopy, RAMAN and nuclear magnetic resonance spectra confirmed molecular structure, revealing presence of D-galacturonic acid backbone. X-ray diffraction patterns revealed an amorphous structure. Differential scanning calorimetry showed endothermic (123 °C) and exothermic peaks (192 °C). Thermogravimetric analysis revealed three decomposition regions, 50–225 °C, 225–400 °C and 400–600 °C. Steady and dynamic shear analyses revealed that pectin had a pseudo-plastic behavior with storage (G?) and loss (G?) modulus increasing with increment in frequency, indicating viscoelastic structure more predominantly elastic than viscous.

(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2022) Alkay, Zühal; Yılmaz, Mustafa Tahsin; Muslu Can, Aslı; İspirli, Hümeyra; Dertli, Enes
In this study, the utilization of LAB (Lactiplantibacillus plantarum, Levilactobacillus brevis, Furfurilactobacillus rossiae, Weissella cibaria) cultures with selected flours of different immature cereal grains (wheat, barley, oat and rye) on sourdough and sourdough bread was investigated. In total, 16 different sourdough breads were produced and microbiological, pH, TTA and rheological properties of sourdoughs at 0, 8 and 24?h were determined. At the beginning of the fermentation, while sourdoughs showed elasticity, they showed viscoelastic properties after 24?h of fermentation. The sugar profile of cereal grains at the stage of milk formation and the sugar groups presented in EPSs isolated from sourdoughs were revealed by HPLC analysis. The sugar groups in sourdoughs were glucose, xylose and arabinose, while the sugars in the immature cereal grains were glucose, fructose and mannose. The highest EPS production level (1882.69?±?8.16) was observed in immature barley flour and Lpb. plantarum containing sourdough and all sourdoughs were found to contain glucan type EPSs. It was observed that the amount of EPS produced by the related species differed significantly under different grain conditions. Besides, it was observed that the sourdough breads produced were harder than the control bread. Novelty Impact Statement: Wheat, barley, oat and rye immature grains and four distinct LAB strains were used during sourdough fermentation. Immature grain type and LAB strain used were determinants for in situ exopolysaccharide (EPS) production. Viscoelastic properties of sourdough and textural properties of sourdough bread were affected by grains and LAB strain utilized.

(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2022) Bozdemir, Ayşegül; Şensu, Eda; Okudan, Emine Şükran; Özçelik, Beraat; Yücetepe, Aysun
In this study, ultrasound-assisted enzymatic extraction was performed to extract proteins from Gracilaria dura for the first time. The ultrasonic applying time (30–300?s), enzyme/substrate (E/S, 0.5–2.5), and extraction time (20–28?h) on protein content (PC), total phenolic content (TPC), and antioxidant activity (AOA) was optimized using response surface methodology. Techno-functional properties of protein extracts obtained under optimum conditions were determined. At optimum conditions (ultrasonic applying time: 257.57?s, E/S: 2.5, extraction time: 22.61?h), PC, TPC, AOACUPRAC and AOAABTS were found as 189.59?mg/g, 60.52?mg GAE/g and 55.66?mg TE/g and 478.50?mg TE/g dw, respectively. The water/oil absorption capacity, foaming capacity/stability, emulsifying activity/stability of the protein extracts were 195?±?0.08%, 568?±?0.10%, 12.5?±?0.00%, 0%, 44?±?0.00%, and 75?±?2.50%, respectively. In conclusion, G. dura protein extracts may have an important potential to improve antioxidant activity and functional properties of various food products due to high antioxidant activity and a good level of water/oil absorption capacity. Novelty impact statement: Macroalgae Gracilaria dura proteins were successfully extracted with high extraction efficiency by extraction process performed with ultrasonication application and enzyme usage. The protein extracts from G. dura can be used to improve the techno-functional and antioxidative properties of various food products due to their acceptable water/oil absorption capacity and emulsifying properties and high antioxidant activity.

Gelir Gruplarına Göre Tüketici Fiyat Endeksi (TÜFE) Hesapları ve Gelir Dağılımı Ölçümü İçin Yeni Bir Öneri
(ISTANBUL UNIV, METHODOLOGY & SOCIOLOGY RESEARCH CENTER, CENTRAL CAMPUS, ISTANBUL 34452, TURKEY, 2022) Daşdemir, Esat
Bu çalışma gelir gruplarına göre tüketici fiyat endeksi (TÜFE) hesaplanması konusunu incelemektedir. Tüketim alışkanlıklarının en büyük belirleyicilerinden biri gelir düzeyidir. Dolayısıyla gelir düzeyine göre bireylerin tüketici mal sepetleri de değişmektedir. Bu bağlamda gelir düzeylerine göre bireylerin karşılaştığı enflasyon oranları farklılık gösterir. Çalışma kapsamında Türkiye Cumhuriyeti ölçeğinde 2006-2021 yılları arasında gelir düzeyi düşük bireylerin daha yüksek enflasyon oranlarıyla karşılaştığı gözlemlenmiştir. Düşük gelir grubunda bulunan bireyler, yüksek gelir grubunda bulunan bireylere göre daha yüksek enflasyon oranları ile karşılaşmaktadır. Bu nedenle gelir düzeyi aynı kalsa dahi, gruplar arası enflasyon farklılığı nedeniyle düşük gelirli gruplar ile yüksek gelirli gruplar arasındaki yaşam standardı farklılığı açılmıştır. Sosyal politikaların planlanması aşamasında gelir dağılımının tespiti ve gelir eşitsizliği önemli bir yer tutmaktadır. Bu nedenle çalışma kapsamında gelir dağılımı analizlerine alım gücündeki değişmelerin dâhil edilmesi önerilmiştir. Bu çalışma Gini katsayısına atıf yapılarak gelir dağılımı hesabında alternatif bir yöntem geliştirilmiştir. Bu yöntemin kullanılması için gelir gruplarını temsil eden tüketici mal sepetleri kullanılarak her gelir grubu için farklı TÜFE hesabı yapılmıştır. Çalışma TÜFE ve gelir dağılımı hesabına getirdiği yenilikçi eleştiriler ile literatüre katkı sunmayı amaçlamaktadır. Bu yönüyle çalışma sosyal politikaların belirlenmesi ve uygulanması aşamalarında politika yapıcılara referans olacaktır.
Homines Sacri of Eskibahçe: An Agambenian Reading of Louis de Bernières’ Birds without Wings
(ISTANBUL UNIV, FAC LETTERS, ISTANBUL UNIV EDEBIYAT FAK BATI DILLERI EDEBIYATLARI BOLUMU ORDU CAD NO 6, ISTANBUL 34134, TURKEY, 2022) Özdinç, Tuğçe
This study aims to provide a political criticism of the 2004 novel Birds without Wings by the English author Louis de Bernières, as the political background and overtly political subplot of the novel render it open to one. In order to develop its own argument the study reads Bernières’ novel through the political concepts of the contemporary Italian thinker Giorgio Agamben, focusing mainly on two of them that can be found in Homo Sacer: Sovereign Power and Bare Life of Agamben, and created by the sovereign in relation with the sovereign exception or ban: The first concept is an indistinct concept of life, namely a naked or as Agamben puts it, a bare life. And the second is the homo sacer (sacred man), the one who dwells in this naked life. Living in a small village named Eskibahçe, the characters in Louis de Bernières’ novel are described as birds without wings that “are always confined to earth, no matter how much [they] climb to the high places and flap [their] arms” by the author himself (2005, p.621) and they are turned into homines sacri (sacred men) during a state of political emergency as the footfall of the upcoming change. Therefore, the study aims to examine all the homines sacri in Birds without Wings of Louis de Bernières by an Agambenian reading.

(EMERALD GROUP PUBLISHING LTD, HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND, 2021) Görür, Hakan; Güzeller, Cem Oktay
Purpose – The main purpose of this study is to create a reliable and valid scale to assess the destination food image perceived by the tourists regarding the food in Turkey within the cognitive and affective image component framework. In line with this purpose, both scale development and scale adaptation studies are conducted, and measurement invariance of the scale for gender is analyzed. Design/methodology/approach – This study uses the survey model among quantitative research methods. Scale development processes are used to assess the cognitive image; the construct validity is analyzed with exploratory factor analysis (n 5 328), confirmatory factor analysis (n 5 425) and convergent and discriminant validity. Scale adaptation processes are followed to assess the affective image, and construct validity is tested with confirmatory factor analysis (n 5 425). The reliability of both scales is investigated with Cronbach’s alpha. Cochran–Mantel–Haenszel (CMH) analysis is conducted for measurement invariance for gender. Findings – Construct validity and reliability provided the desired values in all processes. Measurement invariance results proved that the scale does not change according to genders. Research limitations/implications – The data obtained in this study have geographical limitations, and the data represent tourists visiting Antalya, an important tourism destination in Turkey. Practical implications – The scale will provide concrete information about the destination food image and help practitioners to test the model and develop future strategies for the destination. Originality/value – This study presents an integrated approach to understanding the destination food image and expands theoretical and empirical evidence by creating a scale that measures both cognitive and affective image component. Scale-invariant shows that there is no item bias for analyzed gender and contributes to generalizability.
