Published: May 2024

Due to their special structure and many excellent properties, porous Si3N4 ceramics have a wide range of potential applications as a new structural and functional integrated material. In the present study, porous Si3N4 ceramics with excellent bending properties and satisfactory porosity were prepared by the gel-casting method. The variations in porosity, bending strength, fracture morphology and phase composition of the porous Si3N4 ceramics with different weight fractions of La2O3–MgO sintering additive were investigated. The results showed that the density of porous Si3N4 ceramics increased linearly with the increase of sintering additive content. When the content of sintering additive increased from 2.5 wt.% to 10 wt.%, the porosity of porous ceramics decreased from 30 % to 10 %. With the increase of sintering additive content, the bending strength of the samples first increased and then decreased. When the sintering additive content was 5.0 wt.%, the average bending strength of the samples reached a maximum of 240.88 MPa, and scanning electron microscopy and X-ray diffractometry results showed that β-Si3N4 particles with well-developed pores and a maximum aspect ratio of 5.8 were formed in the porous silicon nitride ceramics. This study provides a reference for the preparation of porous Si3N4 ceramics with good bending properties and porosity.

With the rapid improvement of equipment integration technology, multi-spectrum detectors are integrated into compact volumes and widely used for object detection. Confront with this challenge, it is essential to propose a strategy to design a single-layer metasurface with multi-spectrum responses in microwave and infrared ranges. In this work, we proposed a method of designing meta-atoms, which is capable of achieving functional electromagnetic response at microwave and infrared individually. As a demonstration, a metasurface with four different occupation ratios and coding permutation features is designed, fabricated, and tested. In the microwave band, the pixel meta-atom is designed to realize highly efficient cross-polarization conversion between 5.0 and 10.0 GHz, which shows the metasurface can behave as ultra-low Radar Cross Section (RCS) reflectors in the working band; In the infrared band, different occupation ratio of meta-atoms are designed to realize the infrared emissivity from 0.60 to 0.80 in 3–14 μm, which can be used to exhibit digital infrared camouflage pattern. This work promotes the ability to use single-layer design to achieve digital infrared camouflage and microwave RCS reduction simultaneously. The one-layer design is simple in geometry, simplified in process, low cost in economy, and large scale in fabrication, which can promote practical use in compatible microwave stealth and infrared camouflage.

Published: May 2024

With the rapid development and wide application of visible (VIS) and infrared (IR) detections, it is necessary to explore visible-infrared (VIS-IR) compatible camouflage. Here, we report a VIS-IR compatible and independent camouflage device which is composed of the upper IR-transparent VIS-color-patterned layer and the lower electrochromic IR layer. The upper layer has amorphous photonic structure of polystyrene nanospheres (PSNSs). By customizing the PSNS size, various colors can be realized for VIS camouflage. The lower electrochromic IR layer takes advantage of multiwall carbon nanotubes (MWCNTs) as the electrode as well as the IR active material. Experimental results reveal that different colors (including blue, green, and purple) have been obtained, and the IR emissivity can be electrically regulated from 0.43 to 0.9. Moreover, the prototype also exhibits good electrical stability as well as hydrophobic characteristic (the water contact angle of the outmost surface exceeds 120°). These output performances demonstrate the success of our design strategy for promoting the finding applied in camouflage fields as well as energy conservation fields.
Competitive Effects of Fixed Wireless Access on Wireline Broadband Technologies
Authors: Singer Hal J. , Urschel Augustus H.
Published: May 2024

In this paper, we investigate the potential consumer savings to U.S. home broadband consumers in cable modem monopoly markets, should fixed wireless access technologies become available as a competitive alternative. We use a Choice-Based Conjoint survey and Hierarchical Bayes estimation to calculate the proportion of home broadband consumers that would switch to a fixed wireless access option if it was made available in a cable modem monopoly market. We then utilize a monopoly pricing model to estimate the downward pricing pressure this competition would place on incumbent cable modem monopoly prices. We find that fixed wireless entry at current prices would convert 18 percent of cable-only households and lead to a 37 percent reduction in the price of cable modem service. We also find entry into non-monopoly markets where a fiber-optic broadband alternative already exists, and find muted conversion rates and price reductions. Our results indicate that the deployment of fixed-wireless access would generate substantial consumer savings in cable modem monopoly markets, which constitute 30 precent all cable modem subscribers in the United States.
Brain Responses to Real and Imagined Interpretation of Tonal Versus Atonal Music
Authors: González Almudena , Gamundi Antoni , González Julián J.
Published: May 2024

Professional musicians have been teaching/learning/interpreting Western classical tonal music for longer than atonal music. This may be reflected in their brain plasticity and playing efficiency. To test this idea, EEG connectivity networks (EEG-CNs) of expert cellists at rest and during real and imagined musical interpretation of tonal and atonal excerpts were analyzed. Graphs and connectomes were constructed as models of EEG-CNs, using functional connectivity measurements of EEG phase synchronization in different frequency bands. Tonal and atonal interpretation resulted in a global desynchronization/dysconnectivity versus resting—irrespective of frequency bands—particularly during imagined-interpretation. During the latter, the normalized local information-transfer efficiency (NLE) of graph-EEG-CN’s small-world structure at rest increased significantly during both tonal and atonal interpretation, and more significantly during atonal-interpretation. Regional results from the graphs/connectomes supported previous findings, but only certain EEG frequency bands. During imagined-interpretation, the number of disconnected regions and subnetworks, as well as regions with higher NLE, were greater in atonal-interpretation than in tonal-interpretation for delta/theta/gamma-EEG-CNs. The opposite was true during real-interpretation, specifically limited to alpha-EEG-CN. Our EEG-CN experimental paradigm revealed perceptual differences in musicians’ brains during tonal and atonal interpretations, particularly during imagined-interpretation, potentially due to differences in cognitive roots and brain plasticity for tonal and atonal music, which may affect the musicians’ interpretation.

Published: May 2024

The age-specific development of the three constituent components of multiple endocrine neoplasia type 2 (MEN 2) is incompletely characterized for many of the >30 causative rearranged during transfection (RET) mutations, which this genetic association study aimed to specify. Included in the study were 683 carriers of heterogeneous RET germline mutations: 53 carriers with 1 highest-risk mutation (codon 918); 240 carriers with 8 different high-risk mutations (codon 634); 176 carriers with 16 different intermediate-risk mutations (codon 609, 611, 618, 620, or 630); and 214 carriers with 6 different low-risk mutations (codon 768, 790, 804, or 891).There was a strong genotype-specific development of MEN 2 constituent components, with distinct age gradients from C cell disease to node negative medullary thyroid cancer (MTC), from node negative to node positive MTC, from node positive MTC to pheochromocytoma, and from pheochromocytoma to primary hyperparathyroidism. Primary hyperparathyroidism was not observed among the 53 MEN 2B patients who carried highest-risk mutations (age range: 0.5–50 years), of whom no more than 12 (23%) and 3 (6%) carriers were older than age 30 years and 35 years, respectively. The age-specific development of MTC differed significantly between the four RET risk categories, whereas the age-specific development of pheochromocytoma differed significantly only between the two strongest RET risk categories. No significant differences were noted in the development of primary hyperparathyroidism. These findings delineate age-specific disease manifestation corridors for the three constituent components of MEN 2 by RET genotype. These corridors are useful for initial risk assessment and organ-specific surveillance of newly identified RET carriers going forward.

Authors: Kurul Fatih , As Nusret
Published: May 2024

Scots (Pinus sylvestris L.) and red pine (Pinus brutia Ten.) structural timbers (540 pieces) from Türkiye were first visually graded according to TS 1265 (2012). Then, non-destructive tests were conducted using vibration and time of flight (ToF) methods, followed by destructive tests on a four-point bending test setup according to EN 408 (2012). The vibration method showed a higher correlation than ToF with strength and stiffness. The dynamic modulus of elasticity (MOEd) obtained by the vibration method was 12.3% and 15.4% lower in Scots and red pine, respectively, compared to the ToF method. Mechanical testing determined local MOE was 14% and 15% higher than global MOE for Scots and red pine, respectively. An alternative formula to the existing conversion formula in EN 384 (2018) was derived. The average bending strength of red pine was 7% higher than Scots pine. For visual strength grading, local and global MOE in Scots pine, class 1, 2, and 3 structural timbers were assigned to C35, C27, and C22, respectively. Red pine was assigned to C40, C27, and C24 for local MOE and C35, C24, and C22 for global MOE. In machine strength grading, the grade combination was C40-C30-C22-C16-R for both species. The best results were achieved in settings where vibration method and local MOE were used together. Machine strength grading achieved higher efficiency than visual strength grading.

Se estudió la producción de la planta medicinal Echinacea purpurea en 3 localidades de Costa Rica: Los Santos, a 1650 msnm, temperatura máxima de 26,5°C y mínima de 15,5°C, precipitación promedio de 2635 mm año-1, y suelos franco-arcillo-arenosos de alta fertilidad; Santa Bárbara, a 1250 msnm, temperatura máxima de 27,4°C y mínima de 16,9°C, precipitación promedio de 2924 mm año-1, y suelos francos de fertilidad media; y, Ojo de Agua a 850 msnm, temperatura máxima de 29,1°C y mínima de 19,1°C, precipitación promedio de 2302 mm año-1, y suelos franco-arenosos de fertilidad baja. La mayor cantidad de follaje y raíz se produjo en la zona de Los Santos, seguida por Santa Bárbara y Ojo de Agua, respectivamente. Aun cuando en la zona de Los Santos la densidad de siembra fue solo de 112500 plantas ha-1 comparada con 243000 plantas ha-1 en las otras 2 localidades; parece que las condiciones climáticas prevalecientes a la altura de Los Santos, así como las prácticas culturales utilizadas, favorecieron no sólo la producción de materia seca sino también la acumulación de los metabolitos secundarios de interés. El ingreso económico neto obtenido en la zona de Los Santos fue 47% y 59% mayor que en Santa Bárbara y Ojo de Agua, respectivamente.

Published: May 2024

A computational model is developed to investigate the convective heat transfer properties and the fluid flow characteristics of cupric oxide - water nano-fluid in a horizontal circular pipe aiming to provide insights into optimizing heat transfer in such systems. A twisted tape with varied twist ratios is inserted. This quantitative investigation used five Reynolds number from 4,000 to 12,000 under a uniform heat flux scenario of 25,000 W m−2. All experiments were performed as a single-phase fluid with cupric oxide values of 0, 0.4, 1, and 2% by volume. By reducing the twist ratio and increasing volume concentration, the average heat transfer coefficient of cupric oxide-water nano-fluid was improved. For a twist ratio of 4D, the maximum heat transfer improvement was 228% greater than the plain pipe. The presence of twisted tape with modest step ratios causes the friction factor to grow.

Published: May 2024

The transition from grazing to captive rearing resulted in a significant decline in meat quality. To enhance the quality of meat from captive sheep, we examined the impact of exercise on Sunit lambs. The lambs, with similar body weight and aged 3 months underwent a 90-day period of thought-driven exercise. At the end of the exercise period, we collected colonic contents, epithelial tissues, and the longissimus dorsi muscle, and recorded slaughter performance. Exercise was found to have a significant impact on the content of short-chain fatty acids in the colon. Additionally, it generally reduced the mRNA expression of fatty acid absorption transporter genes in the colonic epithelium and lipid metabolism-related genes in the longissimus dorsi muscle. Furthermore, exercise significantly affected the content of fatty acids in the longissimus dorsi muscle of Sunit lambs, and increased its dressing percentage. Exercise influences the composition of fatty acids of the longissimus dorsi muscle and improves dressing percentage by affecting the digestion, absorption, and metabolism of lipids in Sunit lambs. This could be profitable for the livestock industry, and could alter the nutrition and flavor of lamb meat.
A GEOPOÉTICA DA LAMA: DOS ALAGADOS DO MANGUE A UMA ESTÉTICA DE RESISTÊNCIA
Authors: Soares Camilo
Published: May 2024

RESUMO A partir da geopoética, esse artigo busca introduzir o conceito mais específico da geopoética da lama como forma relevante de abordagem analítica estética para a percepção do estresse ambiental e social do mundo contemporâneo. Para tanto, buscamos, em diversas manifestações artísticas brasileiras, como a poesia, a música, o cinema e as artes visuais, exemplos em que a materialidade e a simbologia da lama são usadas para revelar uma miséria que reflete, de certa forma, o descompasso entre o ser humano e o meio ambiente. Tal descompasso está na reflexão de pensadores de distintas áreas, como o médico e geógrafo Josué de Castro, o poeta e professor Michel Collot, o filósofo Gaston Bachelard, o sinólogo Augustin Berque e os pensadores indígenas Davi Kopenawa e Ailton Krenak. Essa reflexão sobre os espaços atuais acaba revelando as cargas racista e colonial que ainda imperam em suas organizações e ocupações, como apontam Silvio Almeida e Enrique Dussel. No entanto, embora seja indício dessa violência, observamos que a lama possui, devido ao poder de expressão artística de sua elasticidade formal e simbólica, potência política não apenas para denunciar mazelas socioambientais como também para propor resistências e possibilidades, que passam também pela consciência por meio da sensibilização e pela reconciliação do ser humano com seu meio.
Compression behaviour of self-compacting concrete under dynamic loading at different ages

Published: May 2024

Self-compacting concrete (SCC) is widely used in reinforced concrete buildings, owing to its ability to consolidate by weight and its lack of requirement for external vibration. Reinforced concrete buildings can be subjected to high strain rate loading during the early days of construction or in their service life. Thus, it is critical to understand the behaviour of concrete under high strain rate loadings at different ages. Minimal studies have previously focused on the early-age behaviour of concrete under high strain rates. This study tries to fill this gap. It focuses on the behaviour of M40 grade SCC under three levels of strain rate loading at ages of 1, 3, 7, 14 and 28 d. The split-Hopkinson pressure bar (SHPB) was used to test 45 SCC specimens of diameter 100 m and thickness 50 mm at high strain rates, ranging from 30 s−1 to 110 s−1, and the determined compressive strength, peak strain and elastic modulus results are compared with quasistatic test results of SCC specimens. The dynamic increase factor (DIF) determined in the SHPB experiment is compared with the CEB-fib code model. The results indicate that the DIF reduces as the concrete's strength and age increase.

Published: May 2024

Key Points

A total of 8.42 million US adults have high CKD progression risk, and 4.77 million of them have eGFR >60 ml/min per 1.73 m2.

An individual's absolute risk of CKD progression is important in the diagnosis and prognostication of CKD.

Background

CKD is currently defined using GFR or albuminuria. This is on the basis of the relative risk of mortality and kidney outcomes compared with a healthy population and does not consider an individual's absolute risk of CKD progression.

Methods

Using National Health and Nutrition Examination Survey data from 1999 to 2020, we characterized the individual-level absolute 3-year risk of ≥40% decline in eGFR (ml/min per 1.73 m2) or kidney failure (3-year risk) among US adults. We categorized the 3-year risk and considered ≥5% as high risk.

Results

Among 199.81 million US adults, 8.42 million (4%) had a 3-year risk ≥5%, including 1.04 million adults without CKD (eGFR ≥60 and albuminuria <30 mg/g). These high-risk adults without CKD as currently defined had risk factors including hypertension (98%), heart failure (72%), and diabetes (44%). A total of 15.51 million adults had CKD with preserved eGFR (eGFR ≥60 and albuminuria ≥30 mg/g)—3.73 million had a 3-year risk ≥5%, 41% of whom did not have diabetes and thus would not be screened for albuminuria using current screening recommendations. The 3-year risk of CKD progression was low (risk <5%) in 94% of the 5.66 million US adults with CKD stage G3a-A1 (eGFR 45 to <60 and albuminuria <30 mg/g).

Conclusions

Assessment of the individual's absolute risk of CKD progression allowed further risk stratification of patients with CKD and identified individuals without CKD, as currently defined, who were at high risk of CKD progression.

Physiotherapy students’ oral health related knowledge, attitudes and practices at an identified institution of higher learning in KwaZulu-Natal, South Africa
Authors: Nadasan Thayananthee , Maharaj Sonill , Singh Shenuka
Published: May 2024

Background Oral self-care health is integral to general health. However limited studies reflect physiotherapy students’ dental practices such as frequency of toothbrushing, toothbrush replacement, use of oral rinses, dental flossing, use of interdental aids or knowledge of dental plaque. Study objectives This study assessed knowledge, perceptions and oral self-care practices among physiotherapy students. This descriptive cross-sectional survey recruited second- third-, and fourth-year physiotherapy students at an identified training institution in South Africa by means of a self-administered questionnaire ResultsA total of 137 students participated in the study with a response rate of 83%. Participants indicated that 58%(n=79) had good knowledge and 85% (n=117) reported oral self-care practices. Almost all participants (99%; n=136) used a brush with toothpaste; 76% (n=104) brushed twice daily; 53% (n=72) replaced their toothbrush every 3 months and 48% (n=66) rinsed their mouth after eating. More than two-thirds of the study sample (62%; n= 84) used an interdental aid and (37%; n=50) reported dental visits once a year with (74%; n=100) only when necessary. From these 96% (n=132) experienced barriers such as costs (54%; n=71) and inadequate time (42%; n = 55). The majority of participants (72%; n=98) supported oral self-care be included in the physiotherapy curriculum. ConclusionAlthough there were inconsistencies in physiotherapy students’ reported oral health-related knowledge, perceptions and self-care practices, the majority of participants supported the inclusion of dental health into the undergraduate physiotherapy curriculum. This will enhance interprofessional education and improve oral health outcomes for both students and patients.

Published: May 2024

En América Latina y el Caribe alrededor del 80 % de la población vive en las ciudades (ONU Hábitat, 2012). Aunque cuenta con grandes espacios poco poblados, se considera a la región como una de las más urbanizadas del mundo. Según un informe elaborado por ONU Hábitat (2012), la mitad de la población urbana reside en ciudades de menos de 500 000 habitantes. Este proceso de descentralización de la población no fue repentino, sino que adquiere múltiples dimensiones. En primer lugar, el crecimiento de áreas metropolitanas que han absorbido a ciudades más pequeñas. En segundo lugar, los avances logrados en acceso a agua, saneamiento y otros servicios han aumentado el atractivo de las ciudades intermedias y pequeñas. Finalmente, los procesos migratorios (internos e internacionales) son más complejos y se producen fundamentalmente entre ciudades. Asimismo, se producen “movimientos de población dentro de las ciudades, entre el centro de la ciudad y su periferia, así como entre centros urbanos secundarios” (p. 17).
Modernizing public health communication competencies in Canada: A survey of the Canadian public health workforce
Authors: McAlpine Devon , MacKay Melissa , Grant Lauren E. , Papadopoulos Andrew , McWhirter Jennifer E.
Published: May 2024

Objectives

Since the publication of the Core Competencies for Public Health in Canada in 2008, the public health and communication landscape has changed dramatically. Digital media and infodemics have shifted how practitioners must communicate and respond to health information. The age of the current competency framework, which is relied on for workforce development, alongside emerging public health challenges, have prompted calls for modernized competency statements. This study aims to (i) measure self-reported communication competence in the public health workforce, (ii) measure agreement with new communication competency statements, (iii) identify variation in agreement between sub-groups of professionals, and (iv) explore current and needed communication training.

Methods

Using a mixed-methods online survey, a sample of 378 participants in various Canadian public health roles and regions were asked to rate their current communication competence and agreement with a modernized, evidence-based draft communication competency framework. The survey was distributed in both official languages through partner organizations and social media. Descriptive statistics were performed to assess agreement and variation was analyzed in relation to public health roles and experience.

Results

While most participants self-reported communication competence, specific areas were rated lower. All 21 proposed competency statements received high agreement with some variation observed between expertise and experience levels. Demand for communication training is high.

Conclusion

Strong agreement with statements indicates support for a modernized communication competency framework among sampled professionals. Research to gather more evidence surrounding the communication demands of the public health workforce and observed variation in strong agreement for the proposed statements is underway.
‘New’ Luxury or Off-Canon Luxury: A Compendium for the Changing Definition of Classical Luxury
Authors: Gürşen Aylin Ecem
Published: May 2024

This study aims to present a review for understanding the changing definition of luxury consumption. The ‘new’ luxury concept is shaped by democratization, globalization, sustainability, and meeting luxury with non-western societies. Although the first footsteps of new luxury began to be heard in the early 2000s, studies on this subject started to increase after 2010. This review focuses on 129 studies carried out in 2010-2021 to explain new luxury concept. It was concluded that ‘attainable luxury’, ‘creatable luxury’, ‘sustainable luxury’ and ‘rental (shareable) luxury’ can be components of new luxury. Accordingly, a framework was created, and adjacent keywords were presented with references. Finally, a research agenda for this ‘new’ luxury trend was presented. In contrast to the current many literature reviews on luxury treating the issue as a conservative and classical concept, this study focuses on the ‘new luxury’ and its potential horizons.

Authors: Gök Nuri , Ekici Süleyman
Published: May 2024

Since the 2000s, the rivalry between the United States and China has been generally perceived as a threat to American hegemony in the international system. Alongside Asia, Latin America has turned into one of the battlefields of geostrategic rivalry. China has been steadily increasing its influence and presence in the region where the US has regarded as its backyard since the declaration of the "Monroe Doctrine". The US has taken some actions to deter China from having a more influential position in the region. China is being considered as a political and economic alternative to the US by Latin American countries. The main argument of this study is that China has gained an undeniable footprint in Latin America thanks to its long-term, well-planned policies; Beijing can use its growing influence in the region as leverage in case of a conflict with the US in the South-Asia area within the context of a hegemonic war.
Solaris Film Afişinde Yer Alan Kültürel Kodların Göstergebilimsel Analizi
Authors: Demir Can Murat
Published: May 2024

Kültür kavramı geniş bir perspektifte ele alındığında görülecektir ki o sadece yazılı ya da sözlü ürünlerden mütevellit değildir. Kültürün tevarüs edip saklanmasında -sözlü ya da yazılı gelenek dışında- başka üretimler de dikkat çekmektedir. Bu ürünlerden en önemlisi görsel nesnedir. İnsanlığın gelişim aşamalarını sadece yazılı ya da birtakım sözsel aktarımlara dayandırmak hem kültürün içeriksel derinliğine haksızlık etmek hem de uygarlık tarihini eksik okumak anlamına gelecektir. Görsel ürünlerin toplumsal hafızada önemli bir yer tuttuğu bilinmektedir: özellikle eski çağlardan günümüze kadar ulaşmış “mağara resimleri” bu duruma iyi bir örnektir. Bu bağlamda görsel nesneler, kültürün sürdürülebilir olmasında oldukça önemli bir yere sahiptir. Görsel nesnelerin faaliyet alanları ya da yetenekleri üç başlıkla izah edilebilir: İfade Etme, Anlamlandırma ve Haber Verme. İfade Etme, insan varlığının kaçınılmaz bir veçhesidir, iletişimin de ana temasını oluşturan ifade etme insan için elzem bir ihtiyaçtır. Anlamlandırma ise insanın merak duygusundan feyz alır, kültürün ve uygarlığın en önemli aşamasını temsil etmektedir. Haber verme, vicdani bir yükümlülüğün parçası olarak karşımıza çıksa da Tarih biliminin Kültür fenomeniyle buluştuğu önemli bir alanı işgal etmektedir. Bu faaliyet alanlarının toplandığı ve kodlandığı bir mecra olan Afiş, bu çalışmanın ana mecrasına işaret etmektedir. Dolayısıyla afiş, tüm yeteneklerinin ötesinde kültürel bir nesne olarak karşımıza çıkmaktadır. Bu çalışmada, Rus yönetmen Andrey Arsenyeviç Tarkovski’nin Solaris (1972) filmine ait afişte yer alan görsel ve dilsel kodların hangi göstergeler üzerinden nasıl temsil edildiği Roland Barthes tarafından geliştirilen göstergebilimsel çözümleme yöntemiyle analiz edilmeye çalışılacaktır. İncelemede afişin anlam katmanlarının iki farklı düzeyine değinilip düzanlam ve yananlam boyutları ele alınacaktır. Düzanlam, afişte yer alan evrensel ve nesnel değerleri içermekte, yananlam ise öznel ve kültürel değerlerin ön planda tutulduğu çözümleme düzeyidir. İkinci aşamada afişin çözümlemesinden elde edilen bulgularla genel bir değerlendirme yapılarak afişte yer alan kültürel kodlara değinilecektir.
Maske Çocuklarda Duygu Tanımayı Etkiler mi?: Duygunun Çeşidinin, Yaşın ve Ebeveyn Kaygısının Rolü

Published: May 2024

Mevcut çalışma, 47-74 aylık 60 okul öncesi çocuğun maskeli yüzlerden duygu tanıma performanslarını maskesiz yüzlerden duygu tanıma performanslarıyla karşılaştırmış, ayrıca çocukların duygu tanıma performanslarını etkileyebilecek olan duygunun çeşidi, duyguyu sergileyen kişinin yaşı ve ebeveynlerin sağlık kaygıları gibi sosyal faktörlerin rolünü incelemiştir. Çocuklar duygu tanıma görevini tamamlamış, ebeveynler ise Sağlık Anksiyetesi Ölçeği’ni doldurmuşlardır. Çocuklar maskesiz yüzlerdeki duyguları maskeli yüzlerdeki duygulardan daha doğru tanımış; ancak mutluluk, öfke, tiksinme, üzüntü ve korku arasından yalnızca üzüntüyü maskeli yüzlerden maskesiz yüzlere kıyasla daha zor anlamışlardır. Çocuklar maskeli yetişkin yüzlerindeki duyguları maskeli çocuk yüzlerindeki duygulardan daha doğru anlamış, ebeveynlerin sağlık kaygısıyla çocukların maskeli yetişkinlerin duygularını doğru tanıma performansları arasında olumlu ilişki ortaya çıkmıştır. Sonuçlar çocukların duygu tanıma süreçlerinde maskenin yüzdeki ipuçlarını gizlediğini ve özellikle üzüntünün anlaşılmasını güçleştirdiğini göstermiştir. Çocukların maskeli yetişkinlerin duygularını maskeli çocuklarınkinden daha doğru tanımaları ve ebeveynlerinin sağlık kaygılarının maskeli yüzlerden duygu tanımayla ilişkisi sosyal deneyimler ve duygu tanıma becerilerinin bağlantılı olduğunu göstermiştir.
Elektronik Ticarette Müşteri İlişkilerinin Rolü ve Koronavirüs Pandemisinde E-MİY Üzerine Alan Çalışması
Authors: Yıldırım Ülfet , Konyalılar Nil
Published: May 2024

Araştırmada tıp literatürüne koronavirüs pandemisi olarak geçen salgın süreci ve elektronik müşteri hizmetlerinin elektronik ticaret (e-ticaret) hacmine etkilerinin incelenmesi amaçlanmıştır. Çalışma kapsamında; cinsiyet fark etmeksizin on sekiz yaşını doldurmuş örneklem olarak hesaplanmış 288 bireye e-posta ile anket çalışması yapılması için ters huni tekniği kullanılarak, basitten karmaşığa sıralanmış, derecelendirme tercih belirleme tipindeki sorular sunulmuştur. Elde edilen veriler SPSS 24 paket programı vasıtası ile ölçek geçerliliği hususunda Keşfedici Faktör Analizine, hipotezlerin incelenmesi hususunda ise Regresyon Analizine tabi tutulmuştur. Müşteri İlişkileri Yönetimi (MİY) olgusu COVID19 öncesi ve dönemi olmak üzere zaman bazlı olarak ele alınmış olup söz konusu olguyu oluşturan tüm etkenlerin e-ticaretin gelişmesi çok boyutlu değişkenine etkileri incelenmiştir. Çalışma sonucunda; pandemi öncesi müşteri sadakati ve yeniden satın alma isteğinden yola çıkılarak Elektronik Müşteri İlişkileri Yönetimi (e-MİY) ve e-ticaret gelişimi arasında kurulmuş olan hipotezlerin büyük çoğunluğu kabul edildiğinden pandemi öncesi e-MİY’nin e–ticaretin gelişmesine mutlak katkısı olduğundan söz edilebilmektedir. Ancak pandemi döneminde e-MİY’in e-ticaret gelişmesinde katkısı olduğu net bir şekilde ifade edilememektedir.

Ultra-Long Sequencing of Yeast Cells (S. cerevisiae) on ONT Sequencers – A Modified FindingNemo Protocol v1
Authors: Cahyani Inswasti
Published: May 2024

This protocol is a bespoke modification of the FindingNemo protocol (LongRead Club) to enable ultra-long (UL) sequencing of yeast on Nanopore sequencers. We have tested and optimised this in Saccharomyces cerevisae using the obsolete SQK-ULK001 kit. It's not tested yet but we think the new ULK114 can be used to replace ULK001, using exact volumes of the corresponding reagents. Let us know if you have tried it with the new kit! Our best read N50 so far was ~67 kb (look at profile pic). This is not (yet) ultra-long, but may also be due to the distribution of chromosome sizes which is generally smaller than more complex eukaryotes, e.g. mammals.

This study shows the results of a water quality assessment for the Basin of the Cane River, which belongs to Iguaque Flora and Fauna Sanctuary National Natural Park, a naturally protected area formed by the Andean Forest and paramo ecosystems in Colombia. The water quality of this river is impacted by agricultural runoff and domestic wastewater from human activities in the buffer area. This was assessed by using chemical, physical, and biological indexes. The IDEAM, NSF and water quality indexes were based on the European standards of measurement. Further to this, BMPW/Col and ETP biological indexes were analyzed and, amongst these, IDEAM WQI (Water quality index) and ETP showed a good correlation. A similar trend was found between the IDEAM water quality index and BMWP/Col index, showing their potential as a good tool for water catchment, diagnosis, assessment, and management in Andean paramo basins. In total, 537 specimens of macroinvertebrates were collected, identifying 8 taxonomic orders, 16 families and 18 genera. Predominant orders were Trichoptera, Ephemeroptera, and Diptera. Baetidae and Planariidae taxas were found in the three water quality levels, showing a decrease in number with a decrease in water quality. Thus, both species have shown sensibility to water quality parameters and also to riverine habitat quality, being then interesting species to determine water quality, deserving more detailed studies for similar cases in high Andean forests and paramo basins.
Perspectives of Open Education High Students on the Open Learning Mode
Authors: Demirbilek Mesut , Keser Sıtar
Published: May 2024

Open education is an education and instruction network that is widely used to overcome physical and temporal limitations. In the current study, an evaluation was made by taking the opinions of students on the application areas of the open education system in Turkey. In this context, the reasons for students attending open education high schools to switch to open education high schools were examined and a general perspective on open education applications was presented in line with their goals and expectations. To this end, phenomenology, one of the qualitative research methods, was used and students’ opinions and experiences about open education were elicited. The sample of the current study is comprised of 500 open education high school students registered through public education centres. An online questionnaire form consisting of semi-structured open-ended questions was used to collect data in the study. When the findings were examined, it was seen that the reasons for the participants’ enrolment in open education differed. In the analysis performed, it was seen that the reasons for enrolling in open education were grouped under six sub-headings: individual-emotional reasons, familial reasons, economic reasons, health-related reasons, reasons arising from school education processes and environmental-stimulating reasons.
