Diabetes mellitus (DB) is the most challenging and fastest-growing global public health challenge. An estimated 10.5% of the global adult population suffers from diabetes, and almost half of them are undiagnosed. The growing at-risk population exacerbated the shortage of health resources, with an estimated 10.6% and 6.2% of adults worldwide having impaired glucose tolerance (IGT) and impaired fasting glycemia (IFG), respectively. All the current diabetes screening methods are invasive and opportunistic and must be conducted in a hospital or a laboratory by trained professionals. At-risk subjects might remain undetected for years and miss the precious time window for early intervention in preventing or delaying the onset of diabetes and its complications. This study was conducted at KK Women’s and Children’s Hospital of Singapore, and five hundred participants were recruited (mean age 38.73 ± 10.61 years; mean BMI 24.4 ± 5.1 kg/m2). The blood glucose levels, for most participants, were measured before and after 75g of sugary drink using both the conventional glucometer (Accu-Chek Performa) and the wrist-worn wearable. The results obtained from the glucometer were used as the ground truth measurements. We propose leveraging photoplethysmography (PPG) sensors and machine learning techniques to incorporate this into an affordable wrist-worn wearable device to detect elevated blood glucose levels (⩾ 7.8mmol/L) non-invasively. Multiple machine learning models were trained and assessed with 10-fold cross-validation using subject demographic data and critical features extracted from the PPG measurements as predictors. Support vector machine (SVM) with a radial basis function kernel has the best detection performance with an average accuracy of 84.7%, a sensitivity of 81.05%, a specificity of 88.3%, a precision of 87.51%, a geometric mean of 84.54% and F-score of 84.03%. Hence, PPG measurements can be utilized to identify subjects with elevated blood glucose measurements and assist in the screening of subjects for diabetes risk.

Published: October 2023

The sub-6 GHz spectrum and the millimeter wave frequency band, with its huge spectrum, have been exploited in the past years to meet the traffic demands of wireless communication networks. However, the limited and licensed spectrum of these bands cannot support the massive connectivity requirements, the exponential growth of data traffic, and the strict quality-of-service requirements for 6G and beyond wireless systems. Extremely high frequencies, such as optical and terahertz, which offer much wider transmission bandwidths with extreme data rate capabilities, are expected to play key roles in the 6G and beyond era. As a result, future-generation wireless networks will transition from single-band and heterogeneous networks to multi-band networks (MBNs), where various frequency bands coexist. Despite the great potential of MBNs, they face novel challenges from channel modeling, transceiver and antenna design, programmable simulation platforms, standardization activities, and resource allocation. This paper provides a tutorial overview from the communication design perspective of the various frequency bands, elaborating on the above issues. Then, we introduce and examine typical MBN architectures for future networks and provide a detailed overview of state-of-the-art resource allocation problems for existing MBNs that typically operate on two frequency bands. The considered resource allocation optimization problems and solution techniques are discussed comprehensively. We then identify key performance metrics and constraint sets that should be considered for resource allocation optimization in future MBNs and provide numerical results to depict how various system parameters and user behaviors can influence their performance. Finally, we present several potential research issues as future work for the design and performance optimization of MBNs.
Enhancement of localization accuracy based on research of conversion coefficient in coherent Φ-OTDR
Authors: Zhong Zhen , Zou Ningmu , Zhang Xuping , You Chen , Li Meng
Published: October 2023

Recently, a distributed fiber optic sensor named phase optical time domain reflectometer or phase-sensitive optical time domain reflectometer (Φ-OTDR) has been used in the localization and monitoring of earthquake waves, underwater facilities, etc. Precision in the localization of external perturbations on the fiber is crucial for effective problem resolution. The conversion coefficient between the extracted phase signal detected by Φ-OTDR and the corresponding perturbation signal acting on the fiber significantly impacts localization accuracy. Therefore, the characteristic of parameters relative to the conversion coefficient in Φ-OTDR should be deeply researched. Then, based on the established mathematical model of coherent Φ-OTDR, modulus, statistical phase, phase change, and peak difference of coherent Φ-OTDR with and without the static region is analyzed, respectively. The analysis reveals that when coherent φ-OTDR has perturbations homogeneously distributed along the fiber, there is no static region on the phase change-fiber length plane. At this point, although the waveform like the information of external perturbation still can be found in the retrieved phase change in the direction of pulse sequence, the phase change does not have a strictly linear relationship along the fiber. It is different from what was expected in coherent Φ-OTDR having the static region, which means that coherent Φ-OTDR must have the static region if a higher localization accuracy is needed. A localization case demonstrates that the proposed method with the designed static region enhances localization resolution by 210% compared to the traditional coherent φ-OTDR without the static region. These findings underscore the importance of the conversion coefficient and the relevance of the static region in Φ-OTDR for achieving accurate and effective localization.

Published: October 2023

GAN-based tabular synthesis methods have made important progress in generating sophisticated synthetic data for privacypreserving data publishing. However, existing methods do not consider explicit attribute correlations and property constraints on tabular data synthesis, which may lead to inaccurate data analysis results. In this paper, we propose a Controllable tabular data synthesis framework with explicit Correlations and property Constraints, namely C3-TGAN. It leverages Bayesian networks to learn explicit correlations among attributes and model them as control vectors. Such control vectors can guide C3-TGAN to generate synthetic data with complicated property constraints. By conducting comprehensive experiments on 14 publicly available benchmark datasets, we showcase C3-TGAN’s remarkable performance advantage over state-of-the-art methods for synthesizing tabular data.
Unmanned Aircraft Selection for Electronic Warfare: A Combined Multicriteria Decision Analysis Approach
Authors: Santos Caio
Published: October 2023

This study demonstrates the utility of combining different methods of Multicriteria Decision Analysis (MCDA) for selecting Unmanned Aircraft (UA) in Electronic Warfare (EW) applications. We begin by emphasizing the significance of EW in military operations and the critical importance of choosing the most suitable UAs for this dynamic arena.

Our primary goal is to identify the optimal UA among various options, meticulously considering distinct EW criteria. We implement three MCDA techniques: the Analytic Hierarchy Process (AHP), AHP-Gaussian, and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Notably, these methods consistently converge in favor of Alternative 4, substantiating the robustness and minimizing subjective bias.

These findings hold profound implications for strategic decision-making within EW operations and offer a sturdy framework for UA selection. This study not only advances the understanding of UA selection within EW but also underscores MCDA's enduring value as a potent tool for guiding strategic choices.

We anticipate that this work will inspire future research in UA selection, including the exploration of more intricate aircraft and the optimization of EW capabilities through sensor allocation and radiation-absorbing materials. Effective UA integration into EW is pivotal for modern military success, and our research provides a comprehensive roadmap to achieve this objective.

Authors: Storti Francesco
Published: October 2023

Mercenarism and Lordship are deeply linked in the Italy of the 14th and 15th centuries. It is difficult to distinguish between these two realities. Equally, it is difficult to understand the social impact of the mercenary phenomenon in reference to the lordship (this is an original theme). This work aims to clarify these aspects, with the use of new interpretative categories for the analysis of the complicated dynamics through which the two phenomena influenced each other.

PENGEMBANGAN BUMDeS SYARIAH DALAM MEMBANGUN EKONOMI BERKEADILAN DI DESA
Authors: Syaharany Venny , Rahmaini Putri
Published: October 2023

ABSTRACT The village is the smallest unit in a country with the lowest government authority to regulate the interests of the local community. Village Owned Enterprises (BUMDes) are business entities owned by villages to improve community welfare through economic ventures. The development of Sharia-based BUMDes based on sharia principles is one way to achieve this goal. This study used the library research method using library data in the form of books. BUMDes is a business entity whose capital is owned by the village and has developed in many villages in Indonesia, but the majority of BUMDes still use the conventional system and have not implemented a profit-sharing system (sharia). The concept of developing Sharia BUMDes is based on laws and regulations governing the establishment of BUMDes. The development of Sharia BUMDes is expected to increase the religious values of the village community and have a positive impact on their economic life and can provide halal and blessed business results. Keyword: BUMDes Sharia, Economic Development,

Published: October 2023

Objective: As known, COVID-19, stemming from the SARS-CoV-2 virus, exhibits distinct clinical patterns across various variants. This research endeavors to comprehensively analyze the variations in clinical presentations between these variants and the original strain, particularly in pediatric COVID-19 pneumonia cases.
Materials and Methods: Patients diagnosed with COVID-19 pneumonia who were admitted to Mersin City Research and Training Hospital between June 2020-2022, were included in the study. Clinical and laboratory data of the patients were evaluated according to their variant status.
Results: 56% (n=62) of 110 pediatric patients were female, and their average age was 11±5.9 (median 13). 31%(n=34) of the patients were infected with the original strain, 20% (n=22) were alpha, 40% (n=44) were delta, and 9% (n=10) were omicron variant. 6% (n=7) of the patients were asymptomatic, 11% (n=12) were mildly symptomatic, 76% (n=83) were moderate (respiratory distress), and 7% (n=8) were severe clinical patients requiring mechanical ventilation. Fever and shortness of breath were most frequently seen in delta, and cough in alpha variant (p=0.0001;p=0.014;p=0.039,respectively). The most severe disease detected in omicron was alpha, delta and original virüs (p=0.001). No relationship detected between the laboratory values of the patients and the variant status (p>0.05). When patients were compared based on radiological severity, no significant differences were found between the variants (p=0.214). However, when cases were classified according to pneumonia severity, regardless of the variant status, higher levels of ferritin (p=0.0001) and CRP (p=0.037) were observed, while lymphocyte count (p=0.009) decreased with increasing pneumonia severity. It's noteworthy that no patient fatalities occurred.
Conclusion: In our study, the most severe clinical picture was shown in the omicron variant, followed by the alpha variant. But, omicron cases were limited, and it is important to examine variants in a larger population.
Technical Efficiency Analysis of Cassava Farmers on Suboptimal Dry Land
Authors: Triyasari Sri Ratna , Priyanto Moh. Wahyudi
Published: October 2023

The government launched a food diversification program, one of which was cassava so that the population does not depend on rice, and anticipates when rice production decreases due to crop failure. However, cassava production was much lower than rice. There were efforts to utilize suboptimal land to increase cassava suplly for population consumption. Therefore, this study aimed to assess the level of technical efficiency of cassava farming on suboptimal dry land. The research sample of 60 cassava farmers in Jaddih Village, Bangkalan Regency was taken by census to answer the research objectives. Stochastic frontier analysis was used to determine the effect of agricultural inputs consisting of land, seeds, labor, costs, and manure on the production of cassava. Then to determine the effect of age, experience, formal education, non-formal education, and family dependents on cassava insufficiency. The results show that cassava production will increase with the increase in land area, but will decrease with the increase in seedlings. The average technical efficiency of cassava was 87%, where this value will increase if farmers attend non-formal education. This research contributes to policy makers to optimize suboptimal land use, and to farmers to take advantage of production inputs and socio-economic variables that affect production increases and technical efficiency.

Published: October 2023

Revegetation of tropical peat swamp forests (PSF) from former fires with local tree species has strategic value for the recovery of PSF, which has been largely lost and severely degraded by logging, conversion, drainage, and repetitive fires. The PSF recovery will be followed by increased forest cover, CO2 sequestration, O2 production, and peat ecosystem biodiversity. The method of revegetation that guarantees successful planting is still very lacking and has not been widely publicized. The study aimed to analyze the growth of revegetated plants on PSF of former fires. It used a field experiment design with four types of local peat plants, namely ramin (Gonystylus bancanus), punak (Tetramerista glabra), tembesu (Fragraea fragrans), and pulai (Alstonia pneumatophora). The results of the study showed that until the age of 2 years, the survival rate of revegetated plants ranged from 92.56%–94.69%, with growth of 32.53–44.94 cm/year and diameter growth of 0.87–1.21 cm/year. The growth of revegetated plants still accelerated in observations until the age of 3 years. This study provides optimism that PSF revegetation degraded by the fires could be carried out with satisfactory results.

Soybeans are high in protein and vegetable oil. However, soil fertility, among other factors, has resulted in low production. This study aimed to compare the effects of shrimp shells compost extract (EKKU) and Mushroom Substrate Media Compost Extract (EKMTJ) fertilizers in combination with bio-insecticides with active ingredients from Beauveria bassiana on the growth and production of soybean. This was a factorial randomised design study with two factors.  The first factor was compost extract, with P1: EKKU and P2: EKMTJ. Furthermore, the second factor is a dosage of bioinsecticides with B. bassiana active ingredients of 1 litre/ha (B1) and 2 litres/ha (B2). The results showed that the application of shrimp shell compost extract (EKKU) combined with 2 litres/ha bioinsecticide gave the best results in plant height and shoot weight. On the other hand, the application of mushroom substrate medium compost extract (EKMTJ) gave the best results for wet and dry weight of plant pods and canopy dry weight.
Narodziny kina z ducha triku
Authors: Gwóźdź Andrzej
Published: October 2023

Autor wskazuje na ideologię atrakcji jako nieodrodny kinu element konstytuujący jego naturę, począwszy od narodzin w XIX w. po dzień dzisiejszy. Podkreśla ciągłość wynikającą z ontologicznego pokrewieństwa wczesnych atrakcji i współczesnych, cyfrowych efektów specjalnych (np. trik substytucji z przenikaniem i wielokrotną ekspozycją a współczesna estetyka kompozytowania powierzchni obrazowych za pomocą blue screenów; Mélièsowski aktor-figurant a współczesna technika motion capture). Gwóźdź dowodzi ponadto, że Méliès twórczo i perfekcyjnie rozgrywał interfejs: teatr – kino. Wzbogacając teatr ruchomymi obrazami i nie rugując sceny z kina (zachowując np. status performera aranżującego środowisko akcji), prowadził zaawansowane gry intermedialne. W tym sensie Gwóźdź uznaje Mélièsa za prekursora współczesnych metod designowania obrazu filmowego, które z pracy „na obrazie” (a nie z  mise-en-scène) czynią właściwe środowisko triku i prowadzą do eskalacji tego, co niemożliwe: wrażenie rzeczywistości oparte na mimesis zostaje zastąpione wrażeniem rzeczywistości jako triku.
Orkiestra sierżanta Pieprza w żółtej łodzi podwodnej. O płycie i filmie, które zmieniły popkulturę
Authors: Giżycki Marcin
Published: October 2023

W 1966 r. Beatlesi podjęli odważną decyzję: będąc u szczytu popularności, postanowili skończyć z koncertami na żywo. Po pożegnalnym koncercie wzięli kilkumiesięczny urlop nie tylko od występów, ale też nagrań i w ogóle wspólnych działań. Publika spekulowała, czy to koniec zespołu, czy zawiniły kłótnie czy też wypalenie muzyków. Jednakże w 1967 r. Beatlesi wrócili do studia i nagrali „najważniejszy album w historii rocka” – Sgt. Pepper’s Lonely Hearts Club Band. Giżycki pisze o historii powstania albumu, jego charakterze, okładce, wpływie na popkulturę, a przede wszystkim o tym, w jaki sposób przyczynił się do powstania filmu Yellow Submarine, animowanego arcydzieła reżysera George’a Dunninga i rysownika Heinza Edelmanna.
Protocol and Order during the Mourning Period for the Late President Moi: Understanding Official Discourse of the Disciplined Forces and Cultural Ideologies
Authors: Kitetu Catherine Wawasi , Gacheiya Raphael Mwaura
Published: October 2023

This paper is a reflection on both the language and acts of protocol and honour witnessed during the days of mourning and funeral service of the second President of the Republic of Kenya, Daniel Toroitich Arap Moi, between the fourth and the twelfth of February 2020. Interviews with some military officers were used to shed light on the meanings of the texts and acts of honour and protocol. These include; the Presidential Proclamation, the flags traditions, the military marches, and the gun ceremony by army. The army was in charge of most of the ceremonies and activities that took place during that time of mourning. This discourse and honorary acts are contrary to another underplayed disgruntled discourse that those who suffered under the KANU regime had. Is it a cultural thing not to say ill of the departed? Was the media down playing these contrary views because of what they called ‘negative Kenyan groupthink’? Discourse analysis theory was used to help shed light on the intricacies of language and meanings in the discourse of the disciplined forces and other discourses backgrounded in these events yet are part of human experiences and activities. The gist of the paper is how discursive elements in the chosen texts and acts (for this article, the military) have practical, ritual, symbolic, semiotic, and cultural functions. In discussing this one event, the paper endeavours to show the importance of language in revealing social and cultural ideologies and how this knowledge helps in understanding peoples’ lives. As a social practice, language informs the social structure; who the people are, their behaviours and way of life
Mitochondrial dysfunction at the cornerstone of inflammatory exacerbation in aged macrophages
Authors: Maurmann Rafael Moura , Schmitt Brenda Landvoigt , Mosalmanzadeh Negin , Pence Brandt D.
Published: October 2023

Immunosenescence encompasses multiple age-related adaptations that result in increased susceptibility to infections, chronic inflammatory disorders, and higher mortality risk. Macrophages are key innate cells implicated in inflammatory responses and tissue homeostasis, functions progressively compromised by aging. This process coincides with declining mitochondrial physiology, whose integrity is required to sustain and orchestrate immune responses. Indeed, multiple insults observed in aged macrophages have been implied as drivers of mitochondrial dysfunction, but how this translates into impaired immune function remains sparsely explored. This review provides a perspective on recent studies elucidating the underlying mechanisms linking dysregulated mitochondria homeostasis to immune function in aged macrophages. Genomic stress alongside defective mitochondrial turnover accounted for the progressive accumulation of damaged mitochondria in aged macrophages, thus resulting in a higher susceptibility to excessive mitochondrial DNA (mtDNA) leakage and reactive oxygen species (ROS) production. Increased levels of these mitochondrial products following infection were demonstrated to contribute to exacerbated inflammatory responses mediated by overstimulation of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome and cyclic GMP-ATP synthase (cGAS)-stimulator of interferon genes (STING) pathways. While these mechanisms are not fully elucidated, the present evidence provides a promising area to be explored and a renewed perspective of potential therapeutic targets for immunological dysfunction.

Published: October 2023

This case study explores the efficacy of an e-learning portal as perceived by instructors at Mutah University. The research delves into the interplay between the user-friendliness, utility, and technical assistance provided by the e-learning portal and its overall effectiveness. Additionally, it investigates how the effectiveness of the e-learning system impacts instructors' satisfaction and their willingness to continue using the system. Data were gathered from 250 respondents through a self-administered questionnaire and subjected to thorough correlation and regression analyses. The findings reveal that the ease of use, usefulness, and level of technical support offered by the e-learning portal exhibited strong and positive associations with the overall effectiveness of the e-learning system. Furthermore, the effectiveness of the e-learning system was discovered to be significantly linked to instructors' satisfaction and their intent to continue using the system. These discoveries hold significant implications for the design and implementation of e-learning systems and can serve as valuable insights for decision-makers considering the integration of e-learning technologies within higher education institutions.

Intraductal papillary neoplasms of the bile duct (IPNBs) represent a rare variant of biliary tumors characterized by a papillary growth within the bile duct lumen. Since their first description in 2001, several classifications have been proposed, mainly based on histopathological, radiological and clinical features, although no specific guidelines addressing their management have been developed. Bile duct neoplasms generally develop through a multistep process, involving different precursor pathways, ranging from the initial lesion, detectable only microscopically, i.e. biliary intraepithelial neoplasia, to the distinctive grades of IPNB until the final stage represented by invasive cholangiocarcinoma. Complex and advanced investigations, mainly relying on magnetic resonance imaging (MRI) and cholangioscopy, are required to reach a correct diagnosis and to define an adequate bile duct mapping, which supports proper treatment. The recently introduced subclassifications of types 1 and 2 highlight the histopathological and clinical aspects of IPNB, as well as their natural evolution with a particular focus on prognosis and survival. Aggressive surgical resection, including hepatectomy, pancreaticoduodenectomy or both, represents the treatment of choice, yielding optimal results in terms of survival, although several endoscopic approaches have been described. IPNBs are newly recognized preinvasive neoplasms of the bile duct with high malignant potential. The novel subclassification of types 1 and 2 defines the histological and clinical aspects, prognosis and survival. Diagnosis is mainly based on MRI and cholangioscopy. Surgical resection represents the mainstay of treatment, although endoscopic resection is currently applied to nonsurgically fit patients. New frontiers in genetic research have identified the processes underlying the carcinogenesis of IPNB, to identify targeted therapies.
Comparing explicit and implicit ensemble perception: 3 stimulus variables and 3 presentation modes
Authors: Khayat Noam , Pavlovskaya Marina , Hochstein Shaul
Published: October 2023

Visual scenes are too complex for one to immediately perceive all their details. As suggested by Gestalt psychologists, grouping similar scene elements and perceiving their summary statistics provides one shortcut for evaluating scene gist. Perceiving ensemble statistics overcomes processing, attention, and memory limits, facilitating higher-order scene understanding. Ensemble perception spans simple/complex dimensions (circle size, face emotion), including various statistics (mean, range), and inherently spans space and/or time, when sets are presented scattered across the visual scene, and/or sequentially in rapid series. Furthermore, ensemble perception occurs explicitly, when observers are asked to judge set mean, and also automatically/implicitly, when observers are engaged in an orthogonal task. We now study relationships among these ensemble-perception phenomena, testing explicit and implicit ensemble perception; for sets varying in circle size, line orientation, or disc brightness; and with spatial, temporal or spatio-temporal presentation. Following ensemble set presentation, observers were asked if a test image, or which of two test images, had been present in the set. Confirming previous results, responses reflected implicit mean perception, depending on test image distance from the mean, and on its being within or outside ensemble range. Subsequent experiments asked the same observers to explicitly judge whether test images were larger, more clockwise, or brighter than the set mean, or which of two test images was closer to the mean. Comparing implicit and explicit mean perception, we find that explicit ensemble averaging is more precise than implicit mean perception—for each ensemble variable and presentation mode. Implications are discussed regarding possible separate mechanisms for explicit versus implicit ensemble perception.
Webcam eye tracking close to laboratory standards: Comparing a new webcam-based system and the EyeLink 1000
Authors: Kaduk Tobiasz , Goeke Caspar , Finger Holger , König Peter
Published: October 2023

This paper aims to compare a new webcam-based eye-tracking system, integrated into the Labvanced platform for online experiments, to a “gold standard” lab-based eye tracker (EyeLink 1000 - SR Research). Specifically, we simultaneously recorded data with both eye trackers in five different tasks, analyzing their real-time performance. These tasks were a subset of a standardized test battery for eye trackers, including a Large Grid task, Smooth Pursuit eye movements, viewing natural images, and two Head Movements tasks (roll, yaw). The results show that the webcam-based system achieved an overall accuracy of 1.4°, and a precision of 1.1° (standard deviation (SD) across subjects), an error of about 0.5° larger than the EyeLink system. Interestingly, both accuracy (1.3°) and precision (0.9°) were slightly better for centrally presented targets, the region of interest in many psychophysical experiments. Remarkably, the correlation of raw gaze samples between the EyeLink and webcam-based was at about 90% for the Large Grid task and about 80% for Free View and Smooth Pursuit. Overall, these results put the performance of the webcam-based system roughly on par with mobile eye-tracking devices (Ehinger et al. PeerJ, 7, e7086, 2019; Tonsen et al., 2020) and demonstrate substantial improvement compared to existing webcam eye-tracking solutions (Papoutsaki et al., 2017).

A CONTRASTIVE STUDY OF SEMANTIC CHANGE IN ENGLISH AND ARABIC
Authors: Joshi Dr. Jagdish , Awadi Iman Hameed Faraj Al
Published: October 2023

Semantic change refers to the way in which the meaning of a word changes over long or short stretches of time. It can be internally or externally motivated .The equivalent to the paradigm in morphology is ,in semantics , the word field in which words and their meanings stand in a network of relationships .The alteration of meaning occurs because words are constantly used and what is intended by speakers is not exactly the same each time .If a different intention for a word is shared by the speech community and becomes established in usage then a semantic change has occurred. This study is divided into three sections , the first is devoted to semantic change in English ,while the second is going to discuss it in Arabic ; however ,the third section will shed light on some samples chosen from the two languages to show how semantic change practically takes place across their history .The aim of this research is to state the stages of those two languages` development ,types of semantic change ,reasons and processes of word formation in each language . The following conclusions are shown: 1. Semantic change is , just like other types of linguistic change , continuous, not sudden but gradual and universal . 2. Gaps in the historical record between the identifiable stages called for the loss of the middle stage of Arabic , on the one hand , and produced the illusion of discontinuity between Anglo-Saxon and Middle English and between Middle English and Modern English , on the other hand . 3. Causes of semantic change are either linguistic or extra –linguistic . 4. As far as these two languages are concerned , they have passed different stages and were subject to different political and social factors , yet they have almost the same types .
Does Nursing Students' Consciousness of Privacy Affect their Attitudes to Registration and Preservation of Personal Health Data? A Descriptive Study
Authors: ÜLKER Türkan , KORKUT Sevda
Published: October 2023

Objective: This study was aimed to determine the effect of privacy consciousness of nursing students on their attitudes towards registration and preservation of personal health data.
Method: The study was conducted as a descriptive and correlational research with 255 nursing students. The data were collected by using the Student Information Form, the Registration and Preservation of the Personal Health Data Attitude Scale and the Privacy Consciousness Scale. The data were evaluated in the IBM SPSS Statistics 21.0 program. Mann Whitney U and Kruskall Wallis test were used to analyze the mean scores of the scale in terms of descriptive characteristics. Multiple linear regression analysis was performed to determine the predictor of the Registration and Preservation of the Personal Health Data Attitude scores.
Results: The total mean score of the students' the Registration and Preservation of the Personal Health Data Attitude Scale was 4.15±0.43 and the mean total score of the Privacy Consciousness Scale was 4.48±0.48. It was determined that the Registration and Preservation of the Personal Health Data Attitude Scale total score averages of those who received training on the preservation of personal health data were statistically significantly higher than those who did not receive any training (p

Published: October 2023

Objective: This study was carried out to determine the relationship between the attitudes of midwifery students about euthanasia and their religious attitudes.
Methods: The universe of this cross-sectional study consisted of students studying in the midwifery department of a university in eastern Türkiye. The study was carried out with 284 volunteer midwifery students between November and December 2021. Descriptive statistics such as frequency, percentage, mean and standard deviation values were used in the evaluation of the data. Independent samples t-test and one-way analysis of variance (ANOVA) were used for normally distributed variables, and Spearman correlation analysis was used for non-normally distributed variables. The study data were collected through Google Form. Participants were asked a consent question via the Google form to confirm whether they wanted to participate in the study.
Results: The mean total Health Professional Euthanasia Attitude Scale (HPEAS) score of the participants was found as 83.04±16.07, while their mean total Ok-Religious Attitude Scale (ORASI) score was determined as 34.01±6.00. Accordingly, the participants had moderate attitudes about supporting euthanasia, while their religious attitudes were positive.
Conclusions: As a result of this study, it was observed that most of the students had negative attitudes towards euthanasia, and one of the factors that affected these attitudes was religious belief.

The  review  outlines  modern  concepts   of the  relevance  of fixed-dose combination therapy comprising  angiotensin-converting enzyme inhibitor and dihydropyridine calcium  channel  antagonist  as  an antihypertensive component  with the HMG-CoA reductase  inhibitor when treating hypertensive patients. We have identified the realms of its possible  clinical use taking into consideration  the comorbidity  peculiarities. In addition, we provide main features of the current drugs’ clinical pharmacodynamics  and outline their role in real clinical practice.  Nevertheless  the emphasis  was placed on the modern single-pill combination  of amlodipin, atorvastatin and perindopril. We concisely  report the results data collected  from the large, randomized, double-blind major clinical trials regarding the effectiveness of single pill combination  of amlodipine,  atorvastatin and perindopril , primary focusing  on their cardioprotective  features and overall safety profile.
ARE THERE DIGITAL TECH BUBBLES IN CHINA?

Published: October 2023

This exploration employs the generalized supremum augmented Dickey-Fuller (GSADF) approach to explore whether there are digital tech bubbles in China. The empirical results suggest the existence of multiple digital tech bubbles, which are mostly accompanied by an excessive rise. However, the appearance of digital tech bubbles is curbed since 2016, mainly due to the increasing mature regulations in relevant fields. Besides, bubbles in different digital technologies are similar during the same period, which could be attributed to the close relationships among them. Additionally, we further investigate the factors influencing the explosive behaviours, and find that the Chinese stock market positively affects digital tech bubbles, while economic policy uncertainties and situations negatively influence such explosive behaviors. In the context of the new round of scientific and technological revolution and industrial transformation, these conclusions provide valuable implications to achieve the target of constructing a “Digital China” by becoming moderately cautious about potential bubbles in the digital tech industry.

We present a four-step group-finding algorithm for the Gas in Galaxy Groups (G3) initiative, a spin-off of the z ∼ 0 REsolved Spectroscopy Of a Local VolumE (RESOLVE) and Environmental COntext (ECO) surveys. In preparation for future comparisons to intermediate redshift (e.g., the LADUMA survey), we design the group finder to adapt to incomplete, shallow, or nonuniform data. We use mock catalogs to optimize the group finder’s performance. Compared to friends-of-friends (with false-pair splitting), the G3 algorithm offers improved completeness and halo-mass recovery with minimal loss of purity. Combining it with the volume-limited H i census data for RESOLVE and ECO, we examine the H i content of galaxy groups as a function of group halo mass. Group-integrated H i mass M
H I,grp rises monotonically over halo masses M

halo relation. In an appendix, we release RESOLVE DR4 and ECO DR3, including updates to survey redshifts, photometry, and group catalogs, as well as a major expansion of the ECO H i inventory with value-added data products.
