Geri dönüşümün vazgeçilmezi olan, biyoyararlı olarak sınıflandırılan yenilebilir film ve kaplamalar (YFK) biyopolimer materyallerdir. Bugüne kadar çevre dostu olan YFK ile ilgili sayısız çalışma yapılmıştır. Bu çalışmaların birçoğu bitki ekstrelerinin YFK’da kullanılması ile ilgilidir. Söz konusu YFK’a bitki ekstresi ilave edilmesi antioksidan, antimikrobiyal, karekterizasyon (kalınlık, su buharı geçirgenliği, kopma anındaki uzama katsayısı (%E), çekme dayanımı (TS), renk, biyobozunurluk, suda çözünürlük, absorbans-transmittans analizleri, termal gravimetrik analiz (TGA) (kalınlık, su buharı geçirgenliği, kopma anındaki uzama katsayısı (%E), çekme dayanımı (TS), renk, biyobozunurluk, suda çözünürlük, absorbans-transmittans analizleri, termal gravimetrik analiz (TGA) ve diferansiyel taramalı kalorimetre (DSC), yenilebilir filmlerde fourier dönüşümlü kızılötesi spektroskopisi (FT-IR), taramalı elektron mikroskobu (SEM)) (SEM) (yenilebilir filmlerde fourier dönüşümlü kızılötesi spektroskopisi (FT-IR), taramalı elektron mikroskobu (SEM)) özelliklerinin iyileştirilmesi için yapılmaktadır. Ne yazık ki ilave edilen bitki ekstreleri her zaman beklenen etkiyi göstermemektedir. Bu çalışmada Yüksek Öğretim Tez Merkezi, Google Akademik, Web of Science veri tabanları incelenerek bitki ekstresi, yenilebilir film, karakterizasyon, kaplama anahtar kelimeleri kullanılarak, toplamda 78 çalışma analiz edilmiştir. Yapılan çalışmalar incelendiğinde bitki ekstresinin kimyasal yapısı ve filme eklenen dozajının antioksidan aktiviteyi artırıcı yönde etki gösterdiği gözlemlenmiştir. Antimikrobiyal aktivitenin belirlenmesinde ise analiz yönteminin sonucu etkilediği belirtilmiştir. Diğer özelliklerin ise bitki ekstresinin lipofilik ve hidrofilik olmasına bağlı olarak değişkenlik gösterdiği ifade edilmektedir. Sonuç olarak yaptığımız bu çalışma araştırmacılara farklı araştırma konuları geliştirmeleri için katkı sunmaktadır. Dahası genç araştırmacılara YFK’ın karekterizasyon parametreleri kapsamında temel bir kaynak oluşturmaktadır.

Laccases are copper-containing enzymes that can oxidize a wide variety of substrates. Thanks to this feature of laccase, some dyes that cause environmental pollution can be decolorized. Some bacteria, such as Bacillus licheniformis, naturally produce the enzyme laccase. A new affinity column was tested in this study. For this purpose, the extracellular laccase sepharose 4B-L-tyrosine-ρ-aminobenzoic acid produced by bacteria grown in suitable media was isolated by affinity chromatography method. Its purity was checked by SDS-PAGE method. The decolorization effect of some dyestable in textile wastewater of laccase isolated from B. lichenisformis O12 by affinity column was investigated. No mediator was used in this procedure. .As a result, laccase was purified 4.82-fold purification with a yield of 38.3% respectively, The molecular weight of the purified enzyme was determined as ~70 kDa by the SDS-PAGE method. The enzyme showed optimum activity at pH 4.0 and temperature 92°C. The enzyme was found to retain 100% activity even after 12 hours of incubation at 60°C and 92°C. The kinetic parameters were determined with laccase substrates such as ABTS, 2,6-DMP, and guaiacol. The purified laccase was decolorized with varied efficiencies such as 35% of Reactive black, 31% of Acid black 1, 28% of Methylene blue, and 15% of Acid red 27 without the use of any redox mediators. These properties of B. licheniformis O12 laccase enzyme make it a potential candidate enzyme for use in various biotechnological and industrial applications.

Authors: KARAGÖZ Yalçın , KARAGÖZ Kenan
Published: February 2024

Emergence of multi-drug-resistant bacteria poses an imminent and clear threat to human health. Acinetobacter baumanii is such an organism, which may cause up to 40% mortality due to bacteremia. Ranunculus kotschyi, a widespread herb, is utilized in Türkiye for treatment of rheumatism, leg pain and bruises in folk medicine, and also consumed as food. Molecular identification of Ranunculus kotschyi was performed using ITS1 partial sequence, 5.8S and ITS2 partial sequence. Phylogenetic analyses of the plant were conducted. The plant sample was extracted and fractioned using activity guided fractionation to yield an active fraction (RK4A). RK4A was analysed using LC-QTOF-MS and the presence of syringic acid in RK4A was revealed. The antimicrobial effects of RK4A and syringic acid against multi-drug-resistant Acinetobacter baumanii, as well as other pathogens, namely Klebsiella pneumonia, Escherichia coli, Staphylococcus aureus and Enterococcus faecalis, were screened in broth media. Minimum inhibitory concentration (MIC) values were determined using microdilution method. Our results revealed that RK4A and syringic inhibited growth of all tested bacteria in broth. The MIC values of RK4A against Acinetobacter baumanii, Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus, and Enterococcus faecalis were 500, 62.5, 31.25, 125 and 15.525 µg/ml, respectively. The MIC values of syringic acid against Acinetobacter baumanii, Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus, and Enterococcus faecalis were 1000, 62.5, 62.5, 125 and 31.25 µg/ml, respectively. Our results suggest that Ranunculus kotschyi and syringic acid may provide alternatives in the treatment of infections caused by A. baumanii and other multidrug-resistant bacteria. Further research is needed in order to discover action mechanisms of the reported antimicrobial effects and enhance the observed effects of RK4A and syringic acid.

Authors: SAHİN Hasan Alp , ONDER Hasan
Published: February 2024

The freshness of the egg is important for both hatching and human consumption. It is quite difficult to determine the freshness of the egg without damaging it with classical methods. Deep learning is a powerful method used to classify data without processing or with much less processing. In this study, 30 eggs were photographed as experimental material for 29 days and the images obtained were used as data. It is aimed to determine how many days old the eggs are, which are foldered according to the days of the photos obtained. As a result of the study, 91.78% valuation accuracy value was obtained. Obtaining inputs without preprocessing shows that the Deep learning method can be used when a fast decision is required and the machine needs to make its own decision.

Published: February 2024

Family physicians, who are the leaders of primary health care institutions that patients can access easily, should recommend aspirin to patients with suitable indications for primary or secondary protection by evaluating the benefit-harm relationship via the principle of "Primum non nocere". Studies which were conducted in Turkish primary care settings mentioned that there is an irrational and inappropriate use of aspirin in the primary prevention of atherosclerotic cardiovascular diseases. Aspirin has a role in the primary prevention of cardiovascular diseases, in reducing the incidence of colorectal cancer, in protection related to increased thrombosis risk by some oncology drugs, and in protection from pregnancy complications. Recommendations from current guidelines will lead the way to family physicians regarding the use of aspirin.

Erectile Function in Men during the COVID-19 Pandemic
Authors: Fiala Ludek
Published: February 2024

This research focused on two age groups of men (under 40 and over 40 years) and their sexual function during the COVID-19 pandemic. Somatic examinations, including the measurement of hormone levels, were conducted on all patients. The subjects also completed two questionnaires and provided personal history data. The first questionnaire covered the evaluation of erectile function, while the second assessed psychosocial trauma and stress. The results in the first group (men under 40 years of age) showed a correlation between prolactin values and erectile function score results (R = 0.54), between erectile function score results and trauma and psychosocial stress symptoms (R = 0.49) and also between prolactin values and trauma and psychosocial stress symptoms (R = 0.53). The results in the second group (men over the age of 40) showed a correlation between prolactin values and erectile function score results (R = 0.42), between erectile function score results and trauma and psychosocial stress symptoms (R = 0.54) and between free testosterone level and erectile function score results (R = 0.32). These findings support the hypothesis of a different impact of stress on the development of erectile dysfunction in men under 40 and over 40 years of age during COVID-19.

The Role of Social Media in the Experiences of COVID-19 Among Long-Hauler Women: Qualitative Study
Authors: Garrett Camryn , Aghaei Atefeh , Aggarwal Abhishek , Qiao Shan
Published: February 2024

Background

The extant literature suggests that women are more vulnerable to COVID-19 infection and at higher risk for developing long COVID. Due to pandemic mitigation recommendations, social media was relied upon for various aspects of daily life, likely with differences of usage between genders.

Objective

This study aimed to explore the role and functions of social media in the lives of long-hauler women.

Methods

Participants were purposively snowball-sampled from an online health promotion intervention for long-hauler women with COVID-19 from March to June 2021. During this time, one-on-one, semistructured interviews were conducted online until data saturation was agreed to have been achieved (ie, 15 interviews). Interview transcripts and field notes were analyzed using an emergent, inductive approach.

Results

In total, 15 women were enrolled. The main roles of social media included facilitating support group participation, experience sharing, interpersonal connections, and media consumption. Emergent themes demonstrated that participants rely on social media to fulfill needs of emotional support, social engagement, spirituality, health planning, information gathering, professional support, and recreationally for relaxation. As long-hauler women turn to social media to discuss symptom and health management as well as the intention to vaccinate, this study demonstrates both the associated benefits (ie, decreased isolation) and challenges (ie, misinformation, rumination, resentment, jealousy).

Conclusions

The public health implications of these findings support the development of gender-tailored health promotion interventions that leverage the benefits of social media, while mitigating the negative impacts, for women with long COVID.

Authors: Bresolin Paula , Steindal Simen A , Bingen Hanne Maria , Zlamal Jaroslav , Gue Martini Jussara , Petersen Eline Kaupang , Nes Andréa Aparecida Gonçalves
Published: February 2024

Background

In nursing education, bridging the gap between theoretical knowledge and practical skills is crucial for developing competence in clinical practice. Nursing students encounter challenges in acquiring these essential skills, making self-efficacy a critical component in their professional development. Self-efficacy pertains to individual’s belief in their ability to perform tasks and overcome challenges, with significant implications for clinical skills acquisition and academic success. Previous research has underscored the strong link between nursing students’ self-efficacy and their clinical competence. Technology has emerged as a promising tool to enhance self-efficacy by enabling personalized learning experiences and in-depth discussions. However, there is a need for a comprehensive literature review to assess the existing body of knowledge and identify research gaps.

Objective

The aim of this study is to systematically map and identify gaps in published studies on the use of technology-supported guidance models to stimulate nursing students’ self-efficacy in clinical practice.

Methods

This scoping review followed the framework of Arksey and O’Malley and was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR). A systematic, comprehensive literature search was conducted in ERIC, CINAHL, MEDLINE, Embase, PsycINFO, and Web of Science for studies published between January 2011 and April 2023. The reference lists of the included papers were manually searched to identify additional studies. Pairs of authors screened the papers, assessed eligibility, and extracted the data. The data were thematically organized.

Results

A total of 8 studies were included and four thematic groups were identified: (1) technological solutions for learning support, (2) learning focus in clinical practice, (3) teaching strategies and theoretical approaches for self-efficacy, and (4) assessment of self-efficacy and complementary outcomes.

Conclusions

Various technological solutions were adopted in the guidance models to stimulate the self-efficacy of nursing students in clinical practice, leading to positive findings. A total of 7 out of 8 studies presented results that were not statistically significant, highlighting the need for further refinement of the applied interventions. Nurse educators play a pivotal role in applying learning strategies and theoretical approaches to enhance nursing students’ self-efficacy, but the contributions of nurse preceptors and peers should not be overlooked. Future studies should consider involving users in the intervention process and using validated instruments tailored to the studies’ intervention objectives, ensuring relevance and enabling comparisons across studies.
Usability Comparison Among Healthy Participants of an Anthropomorphic Digital Human and a Text-Based Chatbot as a Responder to Questions on Mental Health: Randomized Controlled Trial
Authors: Thunström Almira Osmanovic , Carlsen Hanne Krage , Ali Lilas , Larson Tomas , Hellström Andreas , Steingrimsson Steinn
Published: February 2024

Background

The use of chatbots in mental health support has increased exponentially in recent years, with studies showing that they may be effective in treating mental health problems. More recently, the use of visual avatars called digital humans has been introduced. Digital humans have the capability to use facial expressions as another dimension in human-computer interactions. It is important to study the difference in emotional response and usability preferences between text-based chatbots and digital humans for interacting with mental health services.

Objective

This study aims to explore to what extent a digital human interface and a text-only chatbot interface differed in usability when tested by healthy participants, using BETSY (Behavior, Emotion, Therapy System, and You) which uses 2 distinct interfaces: a digital human with anthropomorphic features and a text-only user interface. We also set out to explore how chatbot-generated conversations on mental health (specific to each interface) affected self-reported feelings and biometrics.

Methods

We explored to what extent a digital human with anthropomorphic features differed from a traditional text-only chatbot regarding perception of usability through the System Usability Scale, emotional reactions through electroencephalography, and feelings of closeness. Healthy participants (n=45) were randomized to 2 groups that used a digital human with anthropomorphic features (n=25) or a text-only chatbot with no such features (n=20). The groups were compared by linear regression analysis and t tests.

Results

No differences were observed between the text-only and digital human groups regarding demographic features. The mean System Usability Scale score was 75.34 (SD 10.01; range 57-90) for the text-only chatbot versus 64.80 (SD 14.14; range 40-90) for the digital human interface. Both groups scored their respective chatbot interfaces as average or above average in usability. Women were more likely to report feeling annoyed by BETSY.

Conclusions

The text-only chatbot was perceived as significantly more user-friendly than the digital human, although there were no significant differences in electroencephalography measurements. Male participants exhibited lower levels of annoyance with both interfaces, contrary to previously reported findings.

Authors: Gautam Kamal , Aguilar Camille , Paudel Kiran , Dhakal Manisha , Wickersham Jeffrey A , Acharya Bibhav , Sapkota Sabitri , Deuba Keshab , Shrestha Roman
Published: February 2024

Background

Men who have sex with men (MSM) are disproportionately burdened by poor mental health. Despite the increasing burden, evidence-based interventions for MSM are largely nonexistent in Nepal.

Objective

This study explored mental health concerns, contributing factors, barriers to mental health care and support, and preferred interventions to improve access to and use of mental health support services among MSM in Nepal.

Methods

We conducted focus groups with MSM in Kathmandu, Nepal, in January 2023. In total, 28 participants took part in 5 focus group sessions. Participants discussed several topics related to the mental health issues they experienced, factors contributing to these issues, and their suggestions for potential interventions to address existing barriers. The discussions were recorded, transcribed, and analyzed using Dedoose (version 9.0.54; SocioCultural Research Consultants, LLC) software for thematic analysis.

Results

Participants reported substantial mental health problems, including anxiety, depression, suicidal ideation, and behaviors. Contributing factors included family rejection, isolation, bullying, stigma, discrimination, and fear of HIV and other sexually transmitted infections. Barriers to accessing services included cost, lack of lesbian, gay, bisexual, transgender, intersex, queer, and asexual (LGBTIQA+)–friendly providers, and the stigma associated with mental health and sexuality. Participants suggested a smartphone app with features such as a mental health screening tool, digital consultation, helpline number, directory of LGBTIQA+-friendly providers, mental health resources, and a discussion forum for peer support as potential solutions. Participants emphasized the importance of privacy and confidentiality to ensure mobile apps are safe and accessible.

Conclusions

The findings of this study have potential transferability to other low-resource settings facing similar challenges. Intervention developers can use these findings to design tailored mobile apps to facilitate mental health care delivery and support for MSM and other marginalized groups.

Social Optimization in Combination with the Theory of Entropy also
Authors: Kageyama Kotaro
Published: February 2024

I have proposed to arrange the technology two-dimensionally, and to consider it three-dimensionally and in time series, as “the criteria for considering the technology”, since before.By the way, entropy express the concept which shows the randomness of molecular structure of material in thermodynamics. I thought whether the concept of entropy could be used in social phenomena in analogy to natural phenomena also, since social phenomena belong to natural phenomena.I think capitalism and democracy have more degree of freedom and diversity, compared to socialism and authoritarianism, therefore the formers is preferable to the latter. Entropy is larger in the former than in the latter.Current capitalism has the weakness of large disparity between rich and poor. The state participation should be required to diminish it. So it is rational that the public policy is based on the upper criteria.The value of the social system is for society to ensure the conditions of life and freedom. From this viewpoint, the coordination between the proper freedom and restriction to it is required. It should be decided by “democratic control by citizens”.Furthermore, whether populism is proper or not proper, is considered based on the upper model of social system, also.
Comparativa de servicios OCR para documentos administrativos en PDF con Java/Tess4J y Python/EasyOCR
Authors: Ortega Cuevas Israel
Published: February 2024

Las entidades y dependencias universitarias manejan documentos administrativos, que a menudo están almacenados en formatos digitales que consisten exclusivamente en imágenes. Esto genera demoras en el acceso al contenido, y dificulta su utilidad en búsquedas y toma de decisiones. Con el propósito de acceder al contenido de texto de estos documentos, se desarrollaron y compararon dos servicios web de procesamiento óptico de caracteres (OCR). El primer servicio está implementado en lenguaje Java, utilizando el marco de desarrollo Spring y la biblioteca Tess4J, mientras que el segundo servicio se ha desarrollado en Python, haciendo uso de la biblioteca EasyOCR. En esta comparación, se evaluaron los tiempos de respuesta al procesar 50 documentos con contenido administrativo y en formato PDF, los cuales contienen información exclusivamente en forma de imágenes. El código fuente de ambos servicios está disponible en el repositorio GitHub, lo que facilita su implementación y uso. Los resultados indican que el servicio Java presenta un tiempo de procesamiento de documentos con una ventaja de dos segundos respecto a Python; sin embargo, se destaca que los resultados pueden variar en condiciones distintas, ya sea porque los algoritmos de OCR utilizados implementan procesos diferentes, o en el caso de documentos de otro ámbito distinto al administrativo, o bien, por encontrarse en equipos con tarjeta gráfica dedicada. Es importante señalar como limitación de este estudio que no se considera la precisión del texto recuperado.

Published: February 2024

Abstract: Binary Phase Shift Keying (BPSK) represents a fundamental modulation technique extensively utilized within digital communication systems. The present study presents an analytical examination of BPSK modulation, with a specific focus on its theoretical aspects, MATLAB implementation, and performance analysis. The article commences by providing an introduction to modulation techniques and a concise overview of BPSK, emphasizing its significance and applications. Theoretical foundations encompassing the mathematical representation, key parameters, and characteristics of BPSK are thoroughly deliberated upon. Performance metrics, namely the bit error rate (BER) and signal-to-noise ratio (SNR), are scrutinized, incorporating theoretical derivations and analysis. Following this, the implementation of BPSK modulation and demodulation in MATLAB is expounded, supplemented by coding algorithms and code snippets. Empirical results acquired from the MATLAB implementation are presented and scrutinized, alongside a comparison to the theoretical analysis. The article concludes by summarizing the principal findings and contributions, accentuating the advantages and limitations associated with BPSK modulation, and suggesting potential avenues for future research within this domain. By concentrating on the theoretical aspects and providing comprehensive derivations and mathematical analysis, this research enhances our understanding and exploration of BPSK modulation, thereby circumventing the reliance on simulation-based methodologies

Abstract: The congestion of vehicles on the road is increasing day by day and also the management of such large traffic by traditional approach isn't adequate enough. In today's scenario the traditional approach works efficiently only if the count is sparse, as the density of vehicles on a particular side of road increases or if the traffic is comparatively larger on one side than other side in such case the approach fails. Hence, we aim to redesign the traffic signal system that is static switching to signal switching, which can performs real-time signal monitoring and handling. So, in this project the switching time of signal will be decided based on real time image detection with good accuracy in dense traffic. This practice can prove its most effectiveness in releasing the congested traffic at an efficient and faster rate.
