Published: October 2023

In order to make up for the shortage of scientific research experiments and teaching in land-based engine room laboratory, a simulation system is designed and developed using B/S mode to simulate scientific research experiments, teaching and operation processes, and designed algorithms to simulate the propulsion characteristics of the main propulsion diesel engine. A large number of experiments were carried out, and the relationship curve between output power and fuel consumption rate of the main engine was obtained in the laboratory. Apache JMeter was used to test the pressure of the simulation system deployed in Dalian Maritime University Cloud. It is found that under the test conditions, the average response time of sample request is 330 ms, which is far superior the design standard of 2 s. There is no abnormal response to all requests, and all indicators fully meet the requirements of the project team. The simulation system fills the gap in the application of panoramic interactive technology in Marine engineering education, and provides a reference for the exploration of "intelligent +" experiment and teaching mode in maritime university laboratories.

Authors: Al-Zahrani Abdulrahman M. , Alasmari Talal
Published: October 2023

This study examines the use of learning analytics to enhance instructional personalization and student engagement in online higher education. The research focuses on the engagement levels of students based on different access methods (mobile and non-mobile), the relationships among engagement indicators, and the strategies for instructional personalization. Quantitative research methodology is employed to analyse and measure students' engagement levels. The findings indicate that students using non-mobile devices exhibit higher engagement in terms of average minutes, item accesses, and content accesses, while mobile access shows higher engagement in terms of course accesses, course interactions, and average interactions. Significant correlations are observed among engagement indicators, highlighting the importance of course interactions, content accesses, and assessment accesses in promoting student engagement. Accordingly, a critical model for effective student engagement in online learning courses is proposed.

Authors: Ren Rupeng , Fang Jun , Hu Jun , Ma Xiaotong , Li Xiaoyao
Published: October 2023

A risk assessment method for urban railway investment and financing based on an improved SVM model under big data is proposed. First, the inner product in the traditional SVM is replaced by a kernel function to obtain a more accurate non-linear SVM, and a classifier with high classification accuracy is achieved by finding the optimal separating hyperplane. Then, a risk index system is constructed based on the grounded theory combining with intuitionistic fuzzy sets, interval intuitionistic fuzzy sets, weighted averaging operators and the distance measure, and the selection method of assessment indexes is analyzed based on the statistical methods. Finally, the SVM model with fuzzy membership is obtained by fuzzifying the input samples of the SVM based on the given rules of fuzzy membership design. The results show that the maximum relative error between the final test results and the actual value is 0.316%, and the minimum relative error is 0.133% with three different test sets being tested in the proposed method, which can accurately assess the investment.

Human-Centric AI to Mitigate AI Biases
Authors: Harfouche Antoine , Quinio Bernard , Bugiotti Francesca
Published: October 2023

The global health crisis represents an unprecedented opportunity for the development of artificial intelligence (AI) solutions. This article aims to tackle part of the biases in artificial intelligence by implementing a human-centric AI to help decision-makers in organizations. It relies on the results of two design science research (DSR) projects: SCHOPPER and VRAILEXIA. These two design projects operationalize the human-centric AI approach with two complementary stages: 1) the first installs a human-in-loop informed design process, and 2) the second implements a usage architecture that aggregates AI and humans. The proposed framework offers many advantages such as permitting to integrate of human knowledge into the design and training of the AI, providing humans with an understandable explanation of their predictions, and driving the advent of augmented intelligence that can turn algorithms into a powerful counterweight to human decision-making errors and humans as a counterweight to AI biases.
Management of Dyslipidemia in Patients with Diabetes Mellitus
Authors: Lee Kyung Ae
Published: October 2023

Most patients with diabetes mellitus (DM) have dyslipidemia, which is characterized by increased triglycerides, decreased high-density lipoprotein cholesterol, and increased small dense low-density lipoprotein cholesterol (LDL-C). Dyslipidemia is an important modifiable risk factor for cardiovascular disease (CVD). Therefore active management is essential. Despite its increasing prevalence, the proportion of patients with adequately-controlled dyslipidemia is small, and efforts to improve this pattern are required. The Korean Diabetes Association guidelines recommend setting goals by evaluating each patient’s future CVD risk, including the presence or absence of CVD, target organ damage, major cardiovascular risk factors, and the duration of DM. The primary target is an LDL-C level below 55 mg/dL (and a reduction in LDL-C level by 50% or more from baseline), 70 mg/dL, and 100 mg/dL from the highest risk group to the lowest risk group, respectively. Statins are the first-line drug of choice, and if the LDL-C target is not reached by a maximum tolerable dose of statin, combination therapy with ezetimibe or proprotein convertase subtilisin/kexin type 9 inhibitors is recommended. In hypertriglyceridemia, lifestyle changes including weight loss and abstinence from alcohol are very important, along with glycemic control.
2023 Clinical Practice Guidelines for Diabetes: Recommendations for Pharmacological Treatment of Type 2 Diabetes
Authors: Noh Junghyun
Published: October 2023

The 2023 clinical practice guidelines for diabetes in Korea are reviewed and updated biennially by the Committee of Clinical Practice Guidelines of the Korean Diabetes Association based on the latest scientific research and clinical trials. The 2023 guidelines include several updates to recommendations for pharmacological treatment of type 2 diabetes. The new guidelines make it clear that the treatment plan should include antidiabetic agents proven to reduce cardiorenal risk in adults with type 2 diabetes and established atherosclerotic cardiovascular disease, heart failure, or chronic kidney disease. When considering injection-based combination therapy, GLP-1 receptor agonists (GLP-1 RAs) are recommended prior to basal insulin. If the target blood glucose level cannot be reached with GLP-1 RAs or basal insulin treatment alone, combination treatment with GLP-1 RAs and basal insulin is recommended. This review summarizes the recommendations for pharmacological treatment for type 2 diabetes in the 2023 Korean Diabetes Association treatment guidelines, focusing on major revisions.
Weighted nonlinear flag manifolds as coadjoint orbits
Authors: Haller Stefan , Vizman Cornelia
Published: October 2023

A weighted nonlinear flag is a nested set of closed submanifolds, each submanifold endowed with a volume density. We study the geometry of Fréchet manifolds of weighted nonlinear flags, in this way generalizing the weighted nonlinear Grassmannians. When the ambient manifold is symplectic, we use these nonlinear flags to describe a class of coadjoint orbits of the group of Hamiltonian diffeomorphisms, orbits that consist of weighted isotropic nonlinear flags.
A new lower bound in the conjecture
Authors: Bright Curtis
Published: October 2023

We prove that there exist infinitely many coprime numbers a, b, c with
$a+b=c$
and
$c>\operatorname {\mathrm {rad}}(abc)\exp (6.563\sqrt {\log c}/\log \log c)$
. These are the most extremal examples currently known in the
$abc$
conjecture, thereby providing a new lower bound on the tightest possible form of the conjecture. Our work builds on that of van Frankenhuysen (J. Number Theory 82(2000), 91–95) who proved the existence of examples satisfying the above bound with the constant
$6.068$
in place of
$6.563$
. We show that the constant
$6.563$
may be replaced by
$4\sqrt {2\delta /e}$
where
$\delta $
is a constant such that all unimodular lattices of sufficiently large dimension n contain a nonzero vector with
$\ell _1$
-norm at most
$n/\delta $
.

Published: October 2023

Minimally invasive surgery is increasingly indicated in the management of malignant disease. Although oesophagectomy is a difficult operation, with a long learning curve, there is actually a shift towards the laparoscopic/thoracoscopic/ robotic approach, due to the advantages of visualization, surgeon comfort (robotic surgery) and the possibility of the whole team to see the operation as well as and the operating surgeon. Although currently there are still many controversial topics, about the surgical treatment of patients with gastro-oesophageal junction (GOJ) adenocarcinoma, such as the type of open or minimally invasive surgical approach, the type of oesophago-gastric resection, the type of lymph node dissection and others, the minimally invasive approach has proven to be a way to reduce postoperative complications of resection, especially by decreasing pulmonary complications. The implementation of new technologies allowed the widening of the range of indications for this type of surgical approach. The short-term and long-term results, as well as the benefits for the patient - reduced surgical trauma, quick and easy recovery - offer this type of surgical treatment the premises for future development. This article reviews the updates and perspectives on the minimally invasive approach for GOJ adenocarcinoma.

Low-income countries carry approximately 90% of the global burden of visual impairment, and up to 80% of this could be prevented or cured. However, there are only a few studies on the prevalence of retinal disease in these countries. Easier access to retinal information would allow differential diagnosis and promote strategies to improve eye health, which are currently scarce. This pilot study aims to evaluate the functionality and usability of a tele-retinography system for the detection of retinal pathology, based on a low-cost portable retinal scanner, manufactured with 3D printing and controlled by a mobile phone with an application designed ad hoc. The study was conducted at the Manhiça Rural Hospital in Mozambique. General practitioners, with no specific knowledge of ophthalmology or previous use of retinography, performed digital retinographies on 104 hospitalized patients. The retinographies were acquired in video format, uploaded to a web platform, and reviewed centrally by two ophthalmologists, analyzing the image quality and the presence of retinal lesions. In our sample there was a high proportion of exudates and hemorrhages—8% and 4%, respectively. In addition, the presence of lesions was studied in patients with known underlying risk factors for retinal disease, such as HIV, diabetes, and/or hypertension. Our tele-retinography system based on a smartphone coupled with a simple and low-cost 3D printed device is easy to use by healthcare personnel without specialized ophthalmological knowledge and could be applied for the screening and initial diagnosis of retinal pathology.

The Poetic Discourse in the Work of J.R. Jiménez
Authors: Burak M. S.
Published: October 2023

This paper analyses the poetic discourse in the work of J.R. Jiménez. Certain extracts from the poem «Espacio» and several verses from the «Eternidades» collection are concerned. Despite the differences in form and style, both prove the Time-concept to be relevant in the author’s work and show affinity in key points. All of them pass over the every-day life concepts. Thus, the author remains Poet every second. The poetry is a sort of a shield for Jiménez in his fight against death and oblivion. His capacity to perceive the nameless things makes his poetic discourse true. In the «Eternidades» one can find rhythm, but no rhyme. In the «Espacio» which is blank verse, Jiménez feels free from formal rules and restrictions. It helps him to translate his pure stream of consciousness into text. Thus, his poetic discourse becomes entirely introspective, and the concept of Consciousness appears to be its key point. Both groups of verses and fragments use common «tricks» that influence reader’s mind in a particular way as they break the linear flow of time. These «tricks» include peculiar use of deictic elements as well as figures of style such as anaphora, paronomasia, polyptoton, etc. The metaphor of dream is of particular importance as it reflects the poetic reality. The trembling drop metaphor is no less significant as is symbolizes the elusive Inspiration. A natural combination of Neoplatonism and Pantheism, of carnivalesque and mystic elements — all that through Time and Consciousness — marks Jiménez as one of the most outstanding writers in human history.

The concept of a Sustainable Work Environment (SWE) has garnered significant attention in recent times, as organizations strive to achieve higher levels of employee well-being and productivity. This paper aims to investigate the influence of SWE on work management and productivity, focusing on three primary objectives: a) understanding the factors contributing to a challenging SWE, b) identifying gaps in existing work environments that hinder performance, and c) comprehending employee perceptions of SWE and its impact on work management practices. To accomplish the research objectives, a mixed-methods approach was employed, combining qualitative and quantitative data collection techniques. Firstly, an extensive review of the relevant literature was conducted, exploring the diverse factors influencing the creation of a challenging SWE (Objective a). This investigation revealed critical aspects such as work-life balance, organizational culture, leadership support, employee involvement, and physical workspace conditions as key determinants of SWE. Subsequently, surveys will be employed to identify specific gaps in the current work environments that impede employee performance (Objective b). The research will highlight the crucial hindrances like inadequate resources, communication barriers, unclear job roles, and lack of employee recognition. The study will also delve into understanding the employee perception of SWE and its effect on work management practices (Objective c). Through employee surveys and feedback, the research will explore more on how employees’ view their work environment impacting their motivation, job satisfaction, and overall work performance. The outcomes of this research may have significant implications for organizations aiming to create a more sustainable and productive work environment. By addressing the identified factors contributing to a challenging SWE and recognizing existing gaps in work management, organizations can proactively design targeted interventions to foster a more supportive and conducive workplace. Cultivating a positive SWE and understanding employee perceptions will lead to greater job satisfaction, reduced turnover rates, and heightened productivity, ultimately driving organizational success.

In today's world, Jatropha curcas plants are a renewable energy feedstock for producing biodiesel to overcome the limitations of natural fuel. The alternative fuel biodiesel can be produced from the Jatropha plant as its seeds contain oil which is one of the important resources for biodiesel. Despite being toxic to many insects and animals, the Jatropha curcas plant is not pest and disease-free. In view of this, our research article presents the formulation and analysis of a mathematical model that describes the Jatropha plantation along with a prediction to control its natural pests by biological pesticides. We assume linear functional response of predators for susceptible pests, and infected pests as infected pests are weaker than susceptible pests and easy to catch. The dynamics of the system around each of the ecologically feasible equilibria are studied. The reduction of disease eradication and coexistence of predator and pest are observed around the predator-free and disease-free equilibrium respectively.

Authors:   , Silva Patricia Soares da
Published: October 2023

Com aumento da população e expansão da produção agrícola, a utilização dos agroquímicos para controle de doenças, pragas e plantas daninhas bem como para elevação da produtividade, se tornou uma ferramenta indispensável. Porém, o uso indiscriminado dos agroquímicos acarreta sérios impactos ao meio ambiente, afetando a qualidade do solo e das águas superficiais e subterrâneas. Neste sentido, considerando a importância do monitoramento de resíduos de agroquímicos no ambiente, este trabalho teve como objetivo o desenvolvimento de um procedimento voltamétrico para determinação de acifluorfen usando um eletrodo de diamante dopado com boro (BDD) como eletrodo de trabalho. A partir de estudos de voltametria cíclica e voltametria de onda quadrada em diferentes janelas de potencial e condições de pH do eletrólito suporte foi possível sugerir um possível mecanismo redox para o analito. Utilizando- se a voltametria adsortiva de redissolução anódica por onda quadrada (SWAdASV) sob condições otimizadas via aplicação de métodos de planejamento experimental, uma curva analítica linear na faixa de concentrações de 0,34 a 4,67 mg L−1 foi obtida, com limite de detecção (LOD) de 0,0069 mg L−1 e limite de quantificação (LOQ) de 0,022 mg L−1. O procedimento apresentou repetibilidade entre 2,22% e 3,18% e porcentagens de recuperação variando entre 92,6% e 112,8% para a análise de amostras de água. O conjunto de resultados apresentados nesta dissertação indica que o procedimento voltamétrico desenvolvido apresenta parâmetros analíticos suficientes para análise de amostras ambientais contaminadas por acifluorfen, além de ser caracterizada pela simplicidade operacional e mais baixo custo.

A Comparative Study on the use of Waste Brick and Glass in Cement Mortars and their Effects on Strength Properties
Authors: DİLEK Hasan , AKPINAR Pınar
Published: October 2023

Sustainable development of the construction industry should use recycled materials to the great- est extent to reduce natural hazards due to the increased accumulation of waste and the deple- tion of natural resources. However, engineering applications using waste materials are always expected to perform satisfactorily. In this aspect, detailed and systematically carried out experi- mental studies are critical in selecting the type and the quantities of waste materials that will be recycled through their use within engineering applications. This study provides systematically produced experimental data on compressive and flexural strength performance to quantitatively compare the effects of using different percentages of waste glass and brick aggregates in cement mortars with a specified workability characteristic. Results show that mortar samples with waste glass aggregates perform better under compressive loading since only around 14% strength de- crease compared to the control mix was yielded with the inclusion of waste glass. In contrast, in both cases, a 30% strength decrease was recorded with the inclusion of waste bricks for 100% replacement of natural sand in the mortars. In the case of flexural strength performance, 50% replacements of natural aggregates with waste bricks and glass yielded around 27% and 38% strength decrease, indicating that using waste brick in cement mortars could result in a better flexural strength performance in comparison, provided that its content is controlled. Replace- ment of natural sand in cement mortars with waste brick and glass yielded less significant flex- ural strength, decreasing the difference between the two types of wastes when the replacement ratio was as high as 100%. Hence, based on the presented experimental evidence, it is concluded that the decision on the type and the quantity of the waste materials to be used should be made considering the area of the use of the mortar and its expected service type.

Published: October 2023

Biomass became the perfect choice for heating in Romanian cities while the geopolitical situation remains still complicated. A selection of cases is presented with several cities using this fuel for heating. A cogeneration with steam boilers, new boilers for warm water or obsoleted ones are all investigated from technical and economical perspectives. The article includes correlations with number of inhabitants, buildings connected to the grid, economical aspects. Conclusions are obtained about the efficiency of biomass district heating for different sizes cities, for different technologies and opportunity to implement modernization projects. The results can enhance the local efforts for a better use of biomass in municipal heating without greenhouse gas emissions. Statistical data about Romanian district heating performance indicators have been used and approved tariffs against average revenues of the population were considered.

Published: October 2023

An energy analysis was performed on a house built in a Southern village of Romania. The house has a typical traditional architecture and size for a single-family dwelling and is made of concrete structural frame and adobe bricks, roofed with unheated attic. The zero-emission building (ZEB) performance could be achieved with proper thermal resistances for envelope elements, an air-to-water heat pump for underfloor heating and DHW and solar- panels mounted on the roof. The analysed house is the third of its kind built in the village neighbourhood in the last 10 years, proving its good living quality and cost affordability, as well as the local market demand. The extension of solutions to existing houses is proven feasible.
Endogenous gold of the russian Altai
Authors: Gaskov Ivan
Published: October 2023

The Altai of Russia in the geological and metallogenic sense includes the Altai Mountains and the northwestern part of Rudny Altai, and in administrative terms - the Altai Territory and the Altai Republic. Gorny Altai has experienced a complex history of geological development, including subduction, accretion-collision and rifting processes with the formation of various types of magmatism and endogenous gold mineralization. The history of gold mining in the region is associated mainly with placers and currently the reserve of placer gold deposits is almost exhausted, and the prospects for primary mineralization have been little studied. In this regard, the problem of assessing the potential of ore gold in known ore occurrences and promising areas of ore clusters has become urgent in the region.In the Russian part of Rudny Altai, gold reserves are mainly associated with gold-bearing pyrite-polymetallic deposits and less with small gold ore occurrences.Gold-sulfide-skarn, epithermal gold-silver, copper-gold-porphyry and gold-mercury types of mineralization may have important practical significance for the region. The increase in ore gold reserves in the Russian part of Rudny Altai is mainly due to additional exploration of pyrite-polymetallic deposits.
ANALISANDO AS CONQUISTAS ALCANÇADAS PELOS PROFESSORES ORIENTADORES NO DESENVOLVIMENTO DO ESTÁGIO EM GESTÃO EDUCACIONAL NO PERÍODO DA PANDEMIA NO CONTEXTO AMAZÔNICO
Authors: Dos Santos Lisboa Sabrina , De Oliveira Alencar Simône
Published: October 2023

O estágio supervisionado na gestão educacional demanda o acompanhamento e orientação do professor orientador, objetivando orientar o estagiário em seu futuro campo de atuação. A demanda de trabalho que os professores orientadores assumem é ampla e complexa. Partindo desse pressuposto, surgiu a questão que norteou a presente pesquisa: quais as percepções dos professores orientadores de estágio em gestão educacional do Instituto de Educação, Agricultura e Ambiente/Humaitá-AM, sobre o desenvolvimento deste componente curricular na formação do novo gestor? Para responder tal questão, traçamos como objetivo central, apresentar as impressões e as reflexões dos professores orientadores de Estágio Supervisionado na Gestão Educacional sobre desenvolvimento do estágio em gestão educacional na modalidade remota. Para isso, realizamos uma pesquisa de campo utilizando a entrevista como instrumento de coleta de dados junto aos professores orientadores de estágio em gestão educacional do IEAA. Os resultados revelaram que o estágio não alcançou os mesmos índices de satisfação do estágio presencial, porém, não houve outra possibilidade de realização. No entanto, abriu espaço para confiança nos estagiários, pois não se sabia realmente se estavam acompanhando o trabalho da gestão escolar sob as plataformas eletrônicas. Outro ponto positivo destacado foi o desenvolvimento de novas metodologias, buscando melhor desempenho nas vias digitais e tornando-se mais flexíveis frente aos seus desafios do ensino remoto.

The Possible Protective Effect of Rutin to Reduce the Effect of Formaldehyde on Lung Tissue and Oxidative Stress in Rats
Authors: A Alsudani Arjwan
Published: October 2023

This study aims to know the therapeutic role of one of the types of plant flavonoids (rutin) in reducing the negative effects resulting from inhalation of formaldehyde 40% and its effect on lung function and tissues of rats. As well as clarifying the effective role of rutin in enhancing the effectiveness of antioxidants and reducing the oxidation process, as rutin acts as a natural antioxidant and can be found in many plant species. In this investigation, a total of twenty-four white male rats were used, and these rats were randomly assigned to four groups, with six rats in each group. The experiment was conducted over a period of three weeks and the first group served as a control, while the other groups (G1, G2, and G3) served as experimental groups. The results of evaluating some antioxidants (SOD, CAT, GSTs, and TAOC) and some oxidants (MDA, NO). revealed a clear imbalance between oxidants and antioxidants, increased oxidative stress, pathological changes in lung tissue such as enlargement and widening of the alveoli, and an increase in endothelial thickness. On the other hand, the rutin dosage increased antioxidants, decreased oxidative stress, and improved lung tissue to levels equivalent to the control group
