Published: March 2023

One of the most significant recent shifts in the emerging economy's housing sector has been an initiative to give the private sector more responsibility for public housing provision through Public-Private Partnerships (PPPs). This intends to improve the living standard and satisfaction among the users of the provided PPPs housing provided. Based on this perception, this study examined the degree of satisfaction among PPPs housing residents in developing economies using Lagos State, Nigeria, as a case study. Through a systematic random sampling, questionnaires were distributed to 180 respondents within the selected PPPs housing in the study area. The study findings indicated a high degree of satisfaction with the location of residents, proximity to the workplace, external appearance, and space allocation among residents of PPPs housing provided. The findings further showed that residents were dissatisfied with the PPPs housing's maintenance practices and community facilities. The study recommended that parties involved in the PPPs housing, especially the government, subsidize materials required to build the houses to reduce costs. The study also suggested that maintenance units should be provided within PPPs housing to avoid damage and deterioration of provided facilities. The study concluded that in meeting residents' degree of satisfaction, community facilities such as waste disposal, security post, and electric power generator and distribution should be adequately provided to improve residents' satisfaction levels within the PPPs housing.

Authors: El-Metwally Salah El-Din E. , Ebrahim Abdelrazek E.
Published: March 2023

For better strength prediction using strut-and-tie models (STM), it is essential to use reliable strength parameters of the model components; e.g., struts, ties, and nodes. Among all the elements of the STM, the strength of the bottle-shaped struts is not well quantified. The purpose of this study is to develop more accurate formulas for the calculation of the effectiveness factors for 2D and 3D bottle-shaped struts that are unreinforced, reinforced with minimum reinforcement, or reinforced with sufficient transverse reinforcement. The nonlinear finite element analysis, with the aid of the software ABAQUS, has been utilized in this study, which has been verified against experimental tests. The study has been carried out for grades of concrete varying from 20 to 100 MPa, and for bearing plate to width ratio varying from 0.1 to 0.9. The obtained formulas for the effectiveness factor are functions of the concrete strength, which is not the case with the ACI 318-19 provisions. These formulas have been verified against experimental tests and have been compared with the ACI 318-19 provisions. The predictions based on these formulas are always on the safe side and are more accurate than those based on the ACI 318-19 provisions.
STUDY ON TENSILE FORCE TRANSMISSION PERFORMANCE OF DECK PLATE
Authors: Kato Daichi , Suzuki Keita , Watanabe Seishi , Takahashi Osamu
Published: March 2023

Floors and roofs in buildings need to be capable of transmitting horizontal forces, such as seismic forces, from the horizontal structure to the vertical structure, in addition to the role of transmitting the weight acting in the vertical direction to the support beams. For this purpose, reinforced concrete slabs are generally used or horizontal braces are installed. However, this requires high material and transportation costs, and several weeks for curing period after concrete is poured. In this study, the possibility that deck plates used as roofing materials can transfer horizontal forces sufficiently without concrete or bracing was investigated. The initial stiffness, maximum load, and yield load are considered, and the yield load is compared with the converted TB (turnbuckle) brace diameter to evaluate the bearing force. Therefore, tensile experiments of deck plates were conducted with the parameters of plate thickness, wave height, and tensile angle. The tensile angle is the angle at which the tensile force is applied to the deck plate perpendicular to the groove direction. As a result, it was found that the lower the wave height and the thicker the plate thickness of the specimen, the higher the stiffness. The yield strength equivalent to TB brace diameter M14 was confirmed for the specimen with a wave height of 50 mm and a plate thickness of 1.6 mm at all tensile angles.
NEW DIRECTIONS IN PREDICTING AND MODELING TRUCK LOAD POPULATIONS INCLUDING OVERLOADS
Authors: Jang Bora , Mohammadi Jamshid
Published: March 2023

Overload trucks often appear as a sizeable portion of truck populations on highways. Within most transportation jurisdictions in the United States, overloads refer to truck weights in excess of 356 kN (80 kips). The load populations exhibit an inconsistent pattern-often with two or more distinct peaks. This paper represents new directions in modeling truck load patterns with capabilities to offer the continuity as well as the bimodal feature of the load data. The method presented is data-driven and uses a bimodal distribution function. The extension of the model to predict the truck load population when data are incomplete or not available is also presented. The parameters required in the model are estimated via the fuzzy regression analysis in the proposed method. The fuzzy regression analysis allows the utilization of subjective and limited information. The Weigh-in-Motion (WIM) data obtained from several stations were used to quantify the parameters of this bimodal distribution function by employing the fuzzy regression analysis. The procedure on obtaining an appropriate distribution function for truck load population is explained along with illustrative examples.

Authors: Tumbaga Joshua , Vimonsatit Sorn , Lopez Jema Rica
Published: March 2023

Green building rating systems are proving to be an effective way to encourage sustainability practices in the construction industry. Green Building Council of Australia (GBCA) has developed four Green Star rating tools that provide a means of certification for building design and construction, operation, fit outs, and communities. The GBCA Green Star rating gives credit to different sustainability aspects of buildings such as energy use in terms of greenhouse gas emissions, embodied energy of materials, water efficiency, and others. This study aimed at determining trends in sustainability practices in the Australian construction industry based on the Green Star credits of certified buildings under the Design and As-built tool. A frequency analysis on the points earned on credits versus the number of projects was done to show perspectives in the industry practice. Analysis of the Green Star credits was also carried out using data available in the literature to further understand the industry motives behind the results. Findings showed that “greenhouse gas emissions”, “indoor pollutants-engineered wood products”, “peak electricity demand reduction”, “potable water” and “sustainable transport” were the credits in which most of the rated buildings had achieved, while life cycle impacts were the credits that certified buildings rarely achieved.
COMPARATIVE CARBON-FOOTPRINT ANALYSIS OF RESIDENTIAL BUILDINGS WITH DIFFERENT STRUCTURAL MATERIALS
Authors: Younis Adel , Dodoo Ambrose
Published: March 2023

An important step towards achieving sustainability goals in the construction sector is taken by developing solutions that adopt ‘greener’ structural materials for buildings. This paper establishes a comparison among four existing residential buildings in Sweden, that utilize different structural solutions, in terms of their global warming potential (GWP). The structural solutions compared are prefabricated reinforced concrete (RC), light timber frame, cross-laminated timber (CLT) panels, and CLT modular construction. For each building, a life cycle assessment (LCA) was performed to estimate the greenhouse gas (GHG) emissions attributable to material production. In general, the results of this study revealed climate benefits associated with timber-based construction, with approximately 50% savings on average in the GHG emissions per unit floor area of the buildings as compared to prefabricated RC construction. Finally, this effort demonstrates the significance of the structural material choice on the overall carbon footprint of a building, especially at the production stage.
Face-Selective Patches in Marmosets Are Involved in Dynamic and Static Facial Expression Processing
Authors: Dureux Audrey , Zanini Alessandro , Everling Stefan
Published: March 2023

The correct identification of facial expressions is critical for understanding the intention of others during social communication in the daily life of all primates. Here we used ultra-high-field fMRI at 9.4 T to investigate the neural network activated by facial expressions in awake New World common marmosets from both male and female sex, and to determine the effect of facial motions on this network. We further explored how the face-patch network is involved in the processing of facial expressions. Our results show that dynamic and static facial expressions activate face patches in temporal and frontal areas (O, PV, PD, MD, AD, and PL) as well as in the amygdala, with stronger responses for negative faces, also associated with an increase of the respiration rates of the monkey. Processing of dynamic facial expressions involves an extended network recruiting additional regions not known to be part of the face-processing network, suggesting that face motions may facilitate the recognition of facial expressions. We report for the first time in New World marmosets that the perception and identification of changeable facial expressions, vital for social communication, recruit face-selective brain patches also involved in face detection processing and are associated with an increase of arousal.

SIGNIFICANCE STATEMENTRecent research in humans and nonhuman primates has highlighted the importance to correctly recognize and process facial expressions to understand others' emotions in social interactions. The current study focuses on the fMRI responses of emotional facial expressions in the common marmoset (Callithrix jacchus), a New World primate species sharing several similarities of social behavior with humans. Our results reveal that temporal and frontal face patches are involved in both basic face detection and facial expression processing. The specific recruitment of these patches for negative faces associated with an increase of the arousal level show that marmosets process facial expressions of their congener, vital for social communication.

Published: March 2023

In brief

Adverse trends in reproductive function are a concern in humans, companion, livestock, and wildlife species. This study indicates that equine populations are at risk of a comparable decline in sperm progressive motility.

There is increasing evidence reporting geographically sensitive adverse trends in human semen quality, with parallel trends observed in the dog sentinel. Despite significant economic and welfare complications associated with poor testicular function, trends in current equine populations are undetermined. Given the predictive value of sperm progressive motility (PMOT) in male factor infertility and fertilisation potential, research determining trends in this parameter is warranted. This research analysed trends in stallion sperm PMOT through systematic review and meta-regression. Using a comprehensive search strategy, Scopus, Embase (Ovid), Medline (Ovid), and VetMed (CAB direct) were scoped for eligible data. Using best practices, 230 meta-data points from 229 articles published from 1991 to 2021 were collated for meta-regression analysis. Sperm PMOT declined significantly between 1984 and 2019 (simple linear regression: b −0.340, P = 0.017; meta-regression: b −0.610, P ≤ 0.001). Overall and yearly PMOT declines were predicted at 33.51 and 0.96%, respectively (1984: 63.69 ± 5.07%; 2019: 42.35 ± 3.69%). Trends remained consistent irrespective of sensitivity analyses. Yearly and overall declines were stronger in western (yearly: 0.75%, overall: 26.29%) compared to non-western (yearly: 0.46%, overall: 10.65%) populations. Adverse trends contribute vital data to the debate surrounding declining semen quality, supporting the use of equines as novel comparative models for human reproduction. Results could have significant economic, health, and welfare consequences for equine breeding sectors. A comparable decline in human, dog, and horse sperm quality is indicative of a common environmental aetiology, indicating the need for a holistic One Health approach in determining causes and developing preventative strategies.
Reinforced strength evaluation of binding material for the restoration of Chinese ancient lacquer furniture
Authors: Zhang Tianxing , Ting Gao , Wu Zhihui , Sun Tian
Published: March 2023

Lacquer, bone glue, and poly(vinyl acetate) (PVAc) were selected in this work as the reinforced binding components for the restoration of lacquer furniture. Three response variables related to the strength of the binding material were studied: cohesive strength of lacquer film, binding situation, and the permeation of adhesive. In addition to mechanical tests, specimens were observed directly and by scanning election microscopy (SEM). The cohesive strength of lacquer film attached by lacquer, bone glue, and PVAc was evaluated on specimens with three kinds of ground layer, including stucco with pig-blood, stucco with lacquer, and the ground layer with titanium dioxide. The permeation of lacquer, bone glue, and PVAc could be determined by SEM. The results shows that strong reinforcement can be achieved by strong cohesive strength of lacquer film, a suitable binding situation, and suitable permeation of the adhesive. Intermediate strength is obtained in the case of intermediate cohesive strength, an intermediate binding situation, and less then optimal permeation. Weak reinforcement results from weak cohesive strength, a poor binding situation, and insufficient permeation.

Published: March 2023

Background and Aims: Transjugular intrahepatic portosystemic shunt (TIPS) is often used in patients with cirrhosis to manage portal hypertension-related complications. Unfortunately, 35-50% of patients develop overt hepatic encephalopathy (HE) after TIPS. However, data on lactulose and rifaximin to prevent post-TIPS HE is limited. Therefore, we aimed to perform a network meta-analysis to investigate the efficacy of multiple pharmacological regimens in the prevention of post-TIPS HE.

Methods: A comprehensive search strategy to identify reports of studies of rifaximin use on post-TIPS hepatic encephalopathy was constructed using truncated keywords, phrases, and subject headings developed in Embase. This strategy was translated to MEDLINE, Cochrane Central Register of Controlled Trials, and the Web of Science Core Collection, with all searches performed on 10 February 2022. No publication date or language limits were used.

Results: The initial search identified 72 studies, and 56 studies were screened after removing duplicates. Five studies, two randomized controlled trials (RCTs) and three retrospective studies, met our inclusion criteria and were included in the final analysis. A total of 840 patients were included, with 65% male. Our meta- analysis did not find a statistically significant difference between lactulose vs placebo/no prophylaxis, nor rifaximin vs placebo/no prophylaxis, nor rifaximin plus lactulose vs placebo/no prophylaxis in the reduction of post-TIPS HE.

Conclusions: Rifaximin alone, lactulose alone, and rifaximin plus lactulose did not significantly reduce the development of post-TIPS HE. Based on the P-scores of the three treatment groups, the combination of rifaximin plus lactulose showed the most promising trend towards preventing post-TIPS HE. More studies, especially large RCTs, are warranted.

Published: March 2023

Background and Aims: Cirrhosis is associated with an increased risk of acute kidney injury (AKI) and hepatorenal syndrome (HRS). Healthcare utilization and cost burden of AKI and HRS in cirrhosis is unknown. We aimed to analyze the health care use and cost burden associated with AKI and HRS in patients with cirrhosis in the United States by using real-world claims data.

Methods: We conducted a case-control study using the Truven Health MarketScan Commercial Claims databases from 2007-2017. A total of 34,398 patients with cirrhosis with or without AKI and 4,364 patients with cirrhosis with or without HRS were identified using International Classification of Diseases, Ninth or Tenth Revision, codes and matched 1:1 by sociodemographic characteristics and comorbidities using propensity scores. Total and service-specific were quantified for the 12-months following versus the 12-months before the first date of AKI or HRS diagnosis and over 12-months following a randomly selected date for cirrhosis controls to capture entire disease burdens.

Results: The AKI and HRS group had a higher number of comorbidities and were associated with higher rates of readmission and mortality. The AKI and HRS groups had a significantly higher prevalence of ascites, spontaneous bacterial peritonitis (SBP), encephalopathy, gastrointestinal bleeding, septic shock, pulmonary edema, and respiratory failure. Compared to patients with cirrhosis only, AKI was associated with higher number of claims per person (AKI vs. cirrhosis only, 60.30 vs. 47.09; p<0.0001) and total annual median health care costs (AKI vs. cirrhosis only, $46,150 vs. $26,340; p<0.0001). Compared to patients with cirrhosis only, the HRS cohort was associated with a higher number of claims per person (HRS vs. cirrhosis only, 44.96 vs. 43.50; p<0.0009) and total annual median health care costs (HRS vs. cirrhosis only, $34,912 vs. $23,354; p<0.0001). Inpatient costs were higher than the control cohort for AKI (AKI vs. cirrhosis only, $72,720 vs. $29,111; p<0.0001) and HRS (HRS vs. cirrhosis only, $ 98,246 vs. $27,503; p<0.0001). Compared to the control cohort, AKI and HRS had a higher rate of inpatient admission, mean number of inpatient admissions, and mean total length of stay.

Conclusions: AKI and HRS are associated with higher health care utilization and cost burden compared to cirrhosis alone, highlighting the importance for improved screening and treatment modalities.

Published: March 2023

Background and Aims: Acid suppression improves dyspepsia symptoms but the efficacy of vonoprazan for functional dyspepsia remains unclear. The aim of this study is to evaluate the effectiveness of vonoprazan therapy for functional dyspepsia without heartburn.

Methods: Patients receiving vonoprazan 10 mg once daily or acotiamide 100 mg three times daily for more than one month were included and retrospectively reviewed. Functional dyspepsia was diagnosed based on the ROME IV criteria. Patients with heartburn were excluded. Eighty-five patients were divided into vonoprazan (n=48) and acotiamide (n=37) groups.

Results: There were no significant differences at baseline between the vonoprazan and acotiamide groups. The functional dyspepsia score significantly improved in both groups (p<0.001). The degree of score reduction (55% vs 59%, p=0.559) and the resolution rates (21% vs 30%, p=0.345) were similar. Epigastric pain and postprandial distress scores were significantly improved in both groups, and the degree of improvement of each score was similar. Constipation and diarrhea scores were significantly improved in both groups, and the degree of improvement similar.

Conclusion: These preliminary results suggest that vonoprazan is effective for the treatment of functional dyspepsia without heartburn in the short-term, with results similar to acotiamide therapy.

Published: March 2023

Background and aims

The lockdown of sports and gambling venues during the coronavirus disease 2019 (COVID-19) pandemic caused a fear of increased gambling on other online gambling types, with a risk for transfer to more addictive gambling than otherwise. This study aimed to estimate changes in gambling activity during COVID-19-affected periods among all gamblers at a Swedish state-owned gambling operator and to analyse observable sex differences.

Methods

This study included gambling tracking data from the Swedish state-owned gambling operator Svenska Spel Sports & Casino (sports betting, online bingo, casino and poker). All individuals (n = 616,245) who gambled at least once from February 10 to July 19, 2020, were included. The study period was divided into four periods according to their expected level of COVID-19 impact on gambling opportunities: one pre-COVID period and three COVID-affected periods (sports cancellation, emerging return of sports, substantial return of sports).

Results

Sports betting experienced an apparent decrease, followed by a gradual normalization and an end level substantially below prepandemic levels. For online bingo, gambling levels increased upon sports interruption and then decreased with the return to normality in sports events but remained higher than baseline levels. We observed a similar trend for online poker during the interruption of sports, but with a lower level than baseline levels when sports events normalized. We noticed a trend favouring online casinos during the sports interruption period regarding gambling intensity but not wagering levels.

Discussion and conclusions

Dramatic changes in the content of the gambling market may divert some gamblers to other gambling types, but maintained effects could not be demonstrated.
The Effectiveness of Story Method in Mutalaah Lessons for Character Education
Authors: Fuad Ahmad , Yunus Badruzzaman M. , Musthafa Izzuddin , Nursobah Asep
Published: March 2023

Character education is essential, especially for the younger generation. Successful character education can be seen in students’ daily behavior, in how they apply vertical relation to God and horizontal regard to His creatures. To perform an effective character education, various methods and learning media can make students more excited at character values in the learning materials. The story method, mutalaah within the al-Qira’ah al-Rashidah Book 1 by Abdul Fatah Shabri Bik and Ali Amir Bik, includes some stories that contain noble morality. This study showed that character education through the story method has several stages, (1) the preparation of the syllabus and lesson plan, (2) the learning activity that covers opening, teaching-learning process, and closing. The process of planting moral values is carried out when a teacher explains the content and text of the lesson. Meanwhile, a formal evaluation is done in the semester test, besides daily assessment of student’s behavior in pesantren; (3) the story method through the learning mutalaah is considered effective in the development of morals because instinctively students like stories and are encouraged and motivated to practice the moral values in the mutalaah stories; (4) some factors supporting character education through the story method include the support of pesantren and principal, teacher’s linear educational background, and availability of decent infrastructure. On the contrary, the inhibiting factors include students’ diverse educational backgrounds, less motivation to study Arabic vocabulary, and lack of learning media that supports the delivery of learning materials.

The use of nanofertilizers has the potential to be used to enrich edible organs with nutrients (biofortification) and improve the biosynthesis of bioactive compounds and their antioxidant capacity. Therefore, the objective of this study was to evaluate the effect of biofortification with magnesium (Mg) nanofertilizer on the accumulation of bioactive compounds and antioxidant capacity in green bean cv. Strike compared to a conventional fertilizer (Mg sulfate). Two sources of Mg were applied via foliar: Nanofertilizer and Mg Sulfate at doses of 0, 50, 100, 200, and 300 mg/L of Mg. The accumulation of total polyphenols, flavonoids, anthocyanins, bioactive compounds, and antioxidant capacity was evaluated in pods. The results obtained in this research confirm the effect of green bean pods biofortified with Mg nanofertilizers on the production and accumulation of bioactive compounds and antioxidant capacity, improving the nutrition and nutraceutical quality of green beans. The 50 mg/L dose of Mg nanofertilizer was the most effective treatment to increase bioactive compounds and antioxidant capacity compared to high doses of Mg sulfate (300 mg/L). This is one of the first studies focused on biofortification with Mg nanofertilizers and their effect on the nutraceutical quality of green beans.

In the utilization of citron melon (Citrullus lanatus var. citroides), it is necessary to deal with a large amount of residues constituted by the peels. These materials commonly discarded can be fully utilized, since they are a source of nutrients. The peels contain not only fibers, but also proteins, sugars and minerals, which, after drying, are concentrated to values that make them interesting for various uses, including for the enrichment of flours or combinations to prepare bakery products. Therefore, the drying of the peels, besides enabling the conservation and storage at room temperature, expands the forms of use and the possibilities of entering the production chain. This study aimed to characterize physico-chemically and determine drying kinetics, effective diffusivity, activation energy and thermodynamic properties of citron melon peels at different drying temperatures. The peels were dried in an oven with forced air circulation, in a thin layer, at temperatures of 60, 70, 80 and 90 °C. With the data collected in the drying, the drying kinetic curves were constructed and eleven mathematical models were fitted to the experimental data. The dried material was crushed in a knife mill and characterized for physicochemical parameters. Midilli model resulted in the best fits, followed by Page and Approximation of Diffusion models. Effective diffusivity increased with drying temperature; activation energy was obtained from the Arrhenius equation and was equal to 8.18 kJ/mol. Enthalpy and entropy were reduced with increased temperature, while Gibbs free energy increased.

Published: March 2023

Identification of plant species and variety has important application value in the process of agricultural production. In this work, we try to use electrochemical fingerprinting technology to collect the electrochemical behavior of electrochemically active substances in plant leaf tissues. Twenty Lycium species and varieties were specifically selected to investigate the recognition ability of electrochemical fingerprinting. Two different extraction solvents and electrolytes were used to create different collection environments. The results show that different Lycium spp. can exhibit different electrochemical fingerprints. Different species of the same species exhibit relatively similar electrochemical fingerprints. After the second derivative processing, the electrochemical fingerprint of plants can be used for classification and recognition by different machine learning models. Partial least squares discriminant analysis (PLS-DA), k-nearest neighbor, (KNN), support vector machine (SVM), random forest (RF) and stochastic gradient boosting (SGB) were used to establish recognition model of Lycium spp. The results show that SGB has the best identification accuracy for electrochemical fingerprint after second derivative treatment.
MODIFICATION OF AMULTIHOLE INJECTOR TO A SINGLE-HOLE INJECTOR AND SPRAY CHARACTERISTICS OF THE MODIFIED INJECTOR BY TWO DIFFERENT IMAGING TECHNIQUES
Authors: Pal Manas Kumar , Bhagwat Aneesh
Published: March 2023

In the present days, almost all the diesel engines are fitted with multihole injectors. Spray characterization of the injectors by different optical measurement techniques is very important to under-stand the air-fuel mixing and combustion procedure inside the cylinder. Instead of characterization of the dense sprays from a real multihole diesel injector, often a single plume is used to study the
spray parameters. In the present work, spray characteristics are studied for a multihole injector with all nozzle holes open and with a single hole open conditions. Experiments have been conducted in a constant-volume, high-pressure, and high-temperature chamber with various injection pressures
and at various ambient conditions. A high-pressure common rail injector with six holes is considered for the study. The penetration and cone angle of the spray from each hole are measured, and the hole-to-hole variation is studied. It has been observed that hole-to-hole variations with respect to spray penetration are prominent in low chamber pressures and injection pressures at the initial stage of injection, though they are minimal at later stages of injection. After that, five holes of the injector are blocked by microwelding, and the remaining single plume was studied and the results compared with the original multiplume spray. The study shows that the penetration length and cone angle
of the single plume match well with that of the multiplumes at all chamber pressures and injection pressures. Later, the spray from the modified single-hole injector was characterized by two different imaging techniques, Mie scattering and diffused backlit imaging (DBI), to compare the penetration length and cone angle measured by the two imaging techniques. It is seen that the differences in
penetration lengths by two imaging techniques are negligible, whereas the cone angles are greater in
the case of backlit shadow imaging, particularly at higher temperatures.

Müşteri beklentilerinin karşılanmaması sebebiyle doğan şikayetler kurumların ürün ve hizmet geliştirme çalışmaları açısından ve rekabet ortamında var olma çabaları açısından etkinlikle yönetilmelidir. Stratejik açıdan kurumların bünyesinde bulunan şikayet yönetimi ekiplerinin müşteri beklentilerini anlayıp uygun çözümler geliştirerek etkili müşteri deneyimi yaratmaları kurumları ileriye taşıyacak önemli stratejik birimlerdir. Gelişim gösteren teknolojik yapı, sosyo ekonomik yapı ve pandemi sürecinin de etkisiyle hizmet sektörünün önemli bir bölümünü kapsayan sağlık alanında hizmet veren kurumlar ve hastalar açısından iletilen şikayetler de oldukça kritiktir. Hasta ve hasta yakınlarının sağlık kurumlarından beklentileri oldukça yüksek olup bu alanda şikayetlerini farklı kanallardan iletebilmektedir. Nitel olarak kurgulanan bu çalışmada on iki özel hastane için iletilen veriler sikayet.var isimli şikayetlerin iletildiği siteden elde edilmiş ve içerik analizi yapılmış. Çalışmada hastaneler için iletilen şikayetlerin %30’u ücretlendirme için yapılan yapılmıştır. Ücret konusundan sonra belirtilen konu ise %28 oranında hizmetlere yönelik şikayetler olmuştur. Ücretlerle ilgili şikayetlerin alt temalarına bakıldığında %47 oranında tedavi ve tetkikler için yüksek ücret talep edilmesi, sunulan hizmetler için %67 oranında tedavilerde aksaklık yaşanması ve personellerle ilgili konularda ise %56 oranında ilgisizlik en çok iletilen alt temalar olmuştur.

Sovyetler Birliği’nde 1989 yılından başlayarak 1990’lı yıllara uzanan, ekonomik ve siyasal anlamda büyük bir değişim olmuştur. Değişim sonucunda bağımsızlığını kazanan birçok ülke siyasal ve yapısal anlamda serbest piyasa ekonomisine geçiş süreciyle karşı karşıya kalmışlardır. Çalışmaya konu olan 14 ülkede geçiş süreci sancılı başlamıştır. Yapısal reformların ekonomik özgürlüklerle desteklenmesi gerekliliği söz konusu ülkelerin süreci faklı yaşamalarına sebep olmuştur. Geçişi erken tamamlayan Baltık ülkeleri ve Doğu Avrupa ülkeleri serbest piyasa ekonomisinde diğerlerine göre süreci daha başarılı yönetmişlerdir. 2020’li yıllara gelindiğinde ekonomik özgürlükler konusunda Güney Kafkas ve Orta Asya ülkelerinin de büyük ilerleme kat etmeleri söz konusu ülkelerin incelenmesinin gerekliliğini ortaya koymuştur. Genel amaç ülkelerin ekonomik anlamda ilerleme kat ederken ekonomik özgürlük kriterlerinde ne düzeyde olduklarını analiz etmektir. On iki ekonomik özgürlük kriteri göz önüne alınarak, en başarılı ülkenin hangisi olduğu analizlerle değerlendirilmiştir. Bu çalışmada Heritage Vakfı’nın yayınlamış olduğu raporda ekonomik özgürlük endeksleri 2020 yılı verileri için SD (Standart Sapma) ve CoCoSo (Birleşik Uzlaşma Çözümü) yöntemlerinden oluşan bir ÇKKV (Çok Kriterli Karar Verme) modeli, SSCB (Sovyet Sosyalist Cumhuriyetler Birliği) ’den ayrılan 14 ülkenin endeksinin analizinde kullanılmıştır. SD yöntemi ile kriter ağırlıkları elde edilmiştir. Yöntemin sonucuna göre en önemli kriter Finansal Özgürlük kriteri olarak belirlenmiştir. CoCoSo yöntemi ile ülkeler değerlendirilmiştir. Yöntemin sonucuna göre ekonomik özgürlük endeksi açısından performansı en iyi olan ülke Gürcistan olarak belirlenmiştir.

Dijital uygulamalar; özellikle ergenlikte kişinin zamanı yönetme becerisiyle eleştirel ve çift düşünme (double-think) yetisi geliştirebilmeleri, toplumsal olaylara duyarlılığı arttırarak ergenlerin sosyalleşme süreçlerine pozitif katkı sağlayabilmeleriyle çoğu bilimsel çalışmaya istenen ve istenmeyen etkileri açısından konu olmuştur. İnternet/ sosyal medya bağımlılığının beden- kişilik algısı üzerindeki etkilerine dair tematik çalışmalar artarken dijital ilişki dinamik ve örüntülerini, özellikle de uzun süreli ilişkideki ya da evli çiftlerdeki dijital flörte bakış açısını inceleyen çalışmalar ise azınlıktadır. Sosyal bilim dalları; sosyal medya (SM) kaynaklı sorunları kültürler kodlarla çözümlemede bir anlamda hazırlıksız ve tecrübesiz yakalanmıştır. Sosyal medyanın özellikle de romantik ilişkilerdeki dijitalleşme sürecindeki etkilerine, siber psikoloji ve nöropsikofizyolojinin yanı sıra sosyoekonomik-iktisadi-siyasi-hukuki unsurları kapsayan iletişim sosyolojisinin, bilişim ve hatta siber kriminoloji bilimlerinin bütüncül odağını koruyarak temkin ve sağduyuyla yaklaşılması gerekliliği doğmuştur. Bu derleme literatür taramasına dayalı olarak konuyu ele almaktadır.

In the civilized era, artificial intelligence (AI) is the imitation of human intellectual functions by machines or computer systems. It is challenging for e-retailers to offer customised discounts despite the unlimited product selection in an online store at the same time, satisfy customers’ expectations while providing a distinctive customer experience. To provide clients with real experiences, recommendations and products must be tailored to their preferences and needs. Therefore, the purpose of this study was to ascertain whether generation Z consumers embrace the use of artificial intelligence (AI) in online buying. This study also aimed to provide recommendations and insights for SMEs to learn more about adopting AI that will enhance their online businesses. For this study, an online survey with quantitative approach is used and gathered 135 respondents. The data were examined by using SPSS version 25. The results of the correlation study showed that each component significantly increases the adoption of AI in online purchasing. The regression research showed that technology literacy has a negative impact on artificial intelligence (AI), while all independent factors (perceived utility, perceived ease of use, and trust) have significant positive impacts on AI (AI). The R² value of the study which is 0.364 indicated good model fit. Due to the AI assistant's constant availability, customers may ask simple questions and report minor difficulties at any time without having to wait for a response. The analysis of client data also helps the online retailer better understand its customers and emerging trends. Thus, advantages like enhanced usability and customisation that satisfy consumer needs and expectations strengthen customer loyalty and boost corporate revenues over the long run.

The airport industry is currently changing rapidly. In the competitive market, airport service providers have to create themselves differently by meeting the needs of travelers better than the competitors. This is because travelers are an airport?s main customers and their first impression of airport facilities and services may influence their feelings towards the airport. Therefore, this study aims to investigate travelers? perceived service quality of the Low-Cost Carrier Terminal (LCCT) as the overall quality would affect the decision of future travelers using the LCCT. A survey was carried out at the main exits of the LCCT after determining a list of factors affecting the airport service quality. Based on the analysis of literature, the authors proposed a system of criteria designed for measuring the quality of airport services according to five service quality dimensions. To test the relationships between the variables, the Statistical Package for Social Sciences (SPSS) is used to analyze survey data collected from 136 travelers at LCCT. The results show that travelers have various views on the service quality provided by the LCCT.
