Published: December 2022

Breast cancer (BC) is a genetic disease in the mammary glands' ducts and lobules, with ductal cancers comprising most of the malignancies. Biomarkers can provide an assessment of cancer diagnosis and prediction. The study aims to compare the expression of serum (miR-21-5p) and CA 15-3 expression in the Iraqi population as more efficient biomarkers, then checked MiRNA-21 main characters as a biomarker comparison with (CA15-3) levels. Circulating serum miRNA-21 expression was measured using (the quantitative Real Time-PCR technique) in 50 patients at various stages of breast cancer compared to 27 healthy controls. Meanwhile, CA 15-3 levels were quantified using electro-chemo luminescence immunoassay (ECLIA) methods. The results show the expression of miRNA-21 and the concentration of CA15-3 increased significantly (p>0.01) in patients as compared to control, but the higher median level of MiRNA-21 than of CA15-3. The ROC curve analysis shows that the accuracy, Overall Model Quality, AUC, sensitivity and specificity of miRNA-21 as a biomarker is much higher than the CA 15-3. In conclusion, miRNA-21 may fill the gap that CA 15-3 still lacks in detecting breast cancer at an early stage. Keywords: Breast cancer, microRNA-21, CA15-3, gene expression, RT-q PCR

Authors: Ahmed Mohammed Rusul , Joudah Fadheel Qayssar
Published: December 2022

Thyme vulgaris is effective in treating acetaminophen toxicity in clinical trials. The present study investigates Thyme aqueous extract's effect on rats poisoned with Acetaminophen. In this study, the data were obtained from male Wister rats. Animals were divided into three groups: distilled water, acetaminophen (1mg/ kg), and aqueous thyme extract (400 mg/kg). All animals were orally treated for seven days respectively. The animal was sacrificed on the eighth day. ALT, AST, GSH, TAC, and Caspase3 were all measured in plasma obtained from heart-derived blood samples centrifuged to determine plasma levels of these enzymes and other antioxidants, malondialdehyde precursors (MDA). Liver enzyme levels were reduced, total antioxidant levels were increased, and an aqueous extract of thyme compensated for glutathione levels. Caspase3 levels were also reduced. Acetaminophen-induced liver tissue damage and inflammatory cell damage were considerably lessened by Aqueous Thyme extract treatment. To protect the liver from Acetaminophen-induced hepatotoxicity, aqueous Thyme extract was found to be beneficial.

With 549,393 new cases recorded in 2018, bladder cancer is one of the most common malignancies worldwide. Urinary bladder cancer is the cause of about 3 percent of all new cancer diagnoses and 2.1 percent of all cancer deaths. This study aims to evaluate the efficiency of the N-myc downstream-regulated gene 1(NDRG1) as a biomarker for bladder cancer patients in the Iraqi population. One hundred individuals in the case-control study were enrolled and divided into two groups. The first group included 50 patients diagnosed with a bladder mass and investigated by undergoing cystoscopy examination for transurethral resection of bladder tumor (TURB). The second group included 50 healthy individuals who had normal bladder tissue. The results of the present study showed the highest level of (NDRG1) among cases with statically significant association (p=0.001). The ROC curve demonstrated that the protein level of (NDRG1) could distinguish disease patients from healthy individuals with a sensitivity of 96% and a specificity of 92%. Serum (NDRG1) protein is an efficient and noninvasive tumor marker for diagnosing bladder cancer.

Published: December 2022

BACKGROUND

Under the trend of normalization of the follow-up epidemic prevention and control, whether the function of intelligent technology will be continuously explored and expanded to reduce the social isolation of the elderly, or whether it will restrict the participation of the elderly in social life and aggravate the social isolation in the post-epidemic era, has become an important issue to be investigated. Based on this background, this paper conducts an in-depth study on the impact of the using intelligent technology on the social isolation of the elderly.

OBJECTIVE

To understand the impact of intelligent technology use on social isolation of the elderly.

METHODS

In 2021, we conducted a cross-sectional online questionnaire with 229 valid samples in China using the purposeful snowball sampling method. Using logistic regression model, this paper analyzed the impacts and differences of using intelligent technology on the social isolation of the elderly, and the robustness test was conducted.

RESULTS

The use of intelligent technology can significantly reduce the social isolation of the elderly. The result is still valid after overcoming the robustness test. Women, middle-aged and elderly people can benefit more from the using intelligent technology to reduce social isolation, and there is no urban-rural difference in the effectiveness of use.

CONCLUSIONS

These results suggest that intelligent technology can become an effective tool to eliminate the digital divide of the elderly and decrease the social isolation of the elderly.

Published: December 2022

BACKGROUND

Mental disorders are prevalent during adolescence. Among the digital phenotypes currently being developed to monitor mental health symptoms, typing behavior is one promising candidate. However, few studies have directly assessed associations between typing behavior and mental health symptom severity, and whether these relationships differs between genders.

OBJECTIVE

In a cross-sectional analysis of a large cohort, we tested whether various features of typing behavior derived from keystroke metadata were associated with mental health symptoms and whether these relationships differed between genders.

METHODS

A total of 934 adolescents from the Future Proofing study undertook 2 typing tasks on their smartphones through the Future Proofing app. Common keystroke timing and frequency features were extracted across tasks. Mental health symptoms were assessed using the Patient Health Questionnaire-Adolescent version, the Children’s Anxiety Scale-Short Form, the Distress Questionnaire 5, and the Insomnia Severity Index. Bivariate correlations were used to test whether keystroke features were associated with mental health symptoms. The false discovery rates of P values were adjusted to q values. Machine learning models were trained and tested using independent samples (ie, 80% train 20% test) to identify whether keystroke features could be combined to predict mental health symptoms.

RESULTS

Keystroke timing features showed a weak negative association with mental health symptoms across participants. When split by gender, females showed weak negative relationships between keystroke timing features and mental health symptoms, and weak positive relationships between keystroke frequency features and mental health symptoms. The opposite relationships were found for males (except for dwell). Machine learning models using keystroke features alone did not predict mental health symptoms.

CONCLUSIONS

Increased mental health symptoms are weakly associated with faster typing, with important gender differences. Keystroke metadata should be collected longitudinally and combined with other digital phenotypes to enhance their clinical relevance.

Authors: Olivia Monita Olivia , Kamaldi Alfian , Ismeddiyanto  , Wibisono Gunawan , Saputra Edy
Published: December 2022

FABA is a by-product of coal combustion in power plants comprising fly ash (FA) and bottom ash (BA) in ratios of 80/20. Fly ash has great potential as a mineral ingredient in concrete, while bottom ash compromises its strength and durability. However, both materials are used to improve the strength and durability of structures in sulfate, chloride, and acidic environments. This research evaluated the properties of blended and high-volume FABA concrete, such as the strength, porosity, weight loss, and sorptivity in organic acidic peat water. OPC (Ordinary Portland Cement) was compared to the blended concrete containing 25% FABA and its high-volume containing 50% and 75% FABA with target strengths of 15, 21, and 29 MPa. The compressive strength of blended and high volume FABA increased during the immersion period, while the porosity and sorptivity rates decreased. Furthermore, the strength of the OPC concrete declined at 28 days, with a gradual marginal weight loss of 5% observed in all mixes. This research suggested that blended and high-volume FABA has potential as a construction material in an acidic peatland environment.
Comparison of Material Point Method and Finite Element Method for Post-Failure Large Deformation Geotechnical Analysis
Authors: Sunanhadikusuma Arif Yunando , Tjung Ezra Yoanes Setiasabda , Lim Aswin
Published: December 2022

Finite Element Method (FEM) has been the state-of-the-art method in geotechnical analysis since it first formulated in the 40s. It capable to handle Multiphysics simulation, soil-structure and soil-water interaction, and time history analysis. Though powerful, the standard Lagrangian FEM suffers mesh distortion when handling large strain deformation problem. This mesh entanglement problem makes post-failure analysis is considerably challenging to model if not impossible to do using FEM. The Material Point Method (MPM) then later introduced to solve these large strain deformation problems. Adapted from the Particle in Cell (PIC) method, MPM is a hybrid method that combines Eularian and Lagrangian approach by utilizing moving material points which are moving over spatially fixed computational mesh. This approach enables MPM to calculate not only fluid mechanics such in PIC but also solid mechanics and its intermediatory states. To demonstrate the capability of MPM and its consistency with FEM in geotechnical analysis, this article presents a comparison of FEM and MPM analysis on a hypothetical slope using Mohr-Coulomb constitutive model. The simulation shows that both FEM and MPM analyses are consistent to each other especially in small strain scheme. However, in large strain deformation, MPM is still able to get convergent result while FEM is not. The MPM simulation is also able to animate post failure behavior clearly, calculate post-failure strains and stresses distribution, and present final geometry of the model.

Published: December 2022

The use of groundwater for drinking purposes is increasing along with population growth and the wider range of human activities that require water. Groundwater is used more often because it is more accessible than surface water. The quality of groundwater suitable for consumption as drinking water must pass physical, chemical and biological parameter tests. This study aims to analyze the comparison of groundwater quality at depths of 30 and 100 meters in the area of the Universitas Muhammadiyah Makassar and determine its suitability as drinking water based on physical, chemical, and biological parameters. This research is an experimental study with water sampling collected at two different locations: 30-meter and 100-meter depth wells. In each well, sampling was carried out three times so that there were six total water samples analyzed in total. Data collection was carried out by observation and laboratory tests. Observations were made by looking directly at groundwater conditions to measure parameters such as odor, color, temperature, and pH, while other parameters were tested in the laboratory. The data analysis results showed differences in the values of the physical, chemical, and biological parameters of groundwater taken at a depth of 30 meters and 100 meters. However, the two samples are still within the standard’s allowable range of values. This study concluded that groundwater at a depth of 100 meters in the Universitas Muhammadiyah Makassar area has better water quality than groundwater at a depth of 30 meters. Therefore, if groundwater at a depth of 30 meters is to be used as drinking water with good quality, it must undergo specific treatment.
Effect Of Creep On The Long-Term Deflection Of Box Girder Balanced Cantilever Bridge Structure Using B3 Model and CEB 2010
Authors: Purba Luki Hariando , Supriyadi Bambang , Suhendro Bambang
Published: December 2022

Creep significantly affects the long-term deflection of the prestressed concrete bridge structure. Some models often used in predicting creep do not consider the water-cement ratio. The water-cement ratio is a factor in the magnitude of creep. If the water-cement ratio is excessive, the creep will also be significant. B3 Model uses the water-cement ratio in predicting creep in prestressed concrete bridge structures and has provided good accuracy with measured deflection data. This study compares B3 Model with Model CEB 2010 to predict the effect of creep on the long-term deflection. The author modeled the bridge structure using Midas Civil 2022 v1.2 software by utilizing the construction stages analysis facility to idealize the balanced cantilever and the effect of creep on the long-term deflection. Envelope displacement of bridge B3 Model is more significant than CEB 2010. The prediction deflection of the B3 Model in 100 years of service life of the bridge is -16.34 cm, while CEB 2010 is -11.90 cm. Creep affects total deflection by 84% to 88%. Creep affects the deflection significant because, in the construction process, each box girder segment is stressed and loaded at the age of 3 days. At the age of 3 days, the elastic modulus of the concrete is still not entirely, and the cement paste on the concrete is still in the hydration process. The results showed a significant difference between B3 Model and CEB 2010. B3 Model predicts that the long-term deflection of the bridge until the end of the bridge's service life is 44% to 49% greater than the CEB 2010 model. Prediction of total deflection until the end of 100 years of bridge service life does not exceed the limit determined by SNI and CEB codes.

Published: December 2022

Abstract: Nowadays, fire disasters are one of the most dangerous events that can occur unexpectedly and inflict significant damage. Humans face serious risks on the job such as heat exhaustion, burns, physical and mental stress. Additionally, they frequently come into contact with high levels of carbon monoxide and other toxic hazards. With these dangerous exposures, this line of work presents a likelihood for many diseases. Humans may not be able to react quickly enough when a fire breaks out. So, in order to solve this problem, a smart firefighter could be created. Similarly, oil tank cleaning is an important task which involves potential hazards such as, fires or explosions, toxic gas and vapor releases, oxygen shortages and other physical dangers. It can even cause exposure to radiation, and environmental contamination, among others. Cleaning the inner surfaces of tight facilities used primarily for storing bulk goods or oils, such as silos, receives special care. The build-up substance, the surface material, and the ambient conditions all influence confined space cleaning technologies. This document discusses four cleaning strategies. The proposed study examines firefighting robots and oil tank cleaning robots in order to achieve better results.

Benchmarking single-photon sources from an auto-correlation measurement
Authors: Sekatski Pavel , Oudot Enky , Caspar Patrik , Thew Rob , Sangouard Nicolas
Published: December 2022

Here we argue that the probability that a given source produces exactly a single photon is a natural quantity to benchmark single-photon sources as it certifies the absence of multi-photon components and quantifies the efficiency simultaneously. Moreover, this probability can be bounded simply from an auto-correlation measurement — a balanced beam splitter and two photon detectors. Such a bound gives access to various non-classicality witnesses that can be used to certify and quantify Wigner-negativity, in addition to non-Gaussianity and P-negativity of the state produced by the source. We provide tools that can be used in practice to account for an imperfect beam splitter, non-identical and non-unit detection efficiencies, dark counts and other imperfections, take finite statistical effects into account without assuming that identical states are produced in all rounds, and optionally allow one to remove the detector inefficiencies from the analysis. We demonstrate the use of the proposed benchmark, non-classicality witness and measure using a heralded single-photon source based on spontaneous parametric down-conversion. We report on an average probability that a single photon is produced ≥55% and an average measure of the Wigner negativity ≥0.004 with a confidence level of 1−10−10.

Al emprender, la identificación de oportunidades es clave para el desarrollo de un negocio. Sin embargo, el temor al fracaso puede tener un rol decisivo, incluso más en situaciones de crisis como la del covid-19. Este estudio determina a partir de una sólida base de datos de emprendimiento en Colombia (la encuesta de población adulta del GEM, 2020), que existen diferencias en el temor al fracaso entre hombres y mujeres, mas no en la identificación de oportunidades. Se encuentran hallazgos congruentes con la literatura y aportes académicos relacionados mostrando que la relación no ha sufrido variaciones en Colombia por el covid-19.
Ecuación de mercado y segmentación por derivación matemática: un modelo gerencial de toma de decisiones empresariales
Authors: Sánchez-Sánchez Juan Diego
Published: December 2022

El artículo presenta una propuesta de modelo matemático y gerencial de toma de decisiones comerciales para la gestión empresarial. Este se basa en el análisis de la teoría de la segmentación de mercados, pero ligada al cálculo específico de los valores de los diferentes niveles de mercado existentes, por medio del uso de una ecuación de mercado basada en el costo, coeficiente de retorno o mercado, y su correspondiente nivel de segmentación. Los datos son gestionados en una única ecuación que, al ser derivada matemáticamente, permite establecer el valor económico de un producto o servicio en una determinada condición de mercado. Este modelo permite la correcta toma de decisiones respecto a la escogencia de una estrategia de segmentación particular.

Los insectos plaga, son especies de organismos vivos que en forma constante se encuentran en poblaciones altas, ocasionando daños económicos en los cultivos. Generalmente, suele tratarse de especies puntuales, por lo general, sólo una o dos, que pueden causar gran afectación económica en el sector de la agricultura. En las últimas 3 décadas se ha venido desarrollando el concepto de un proceso biológico, detectado en eucariotas ampliamente, mediante el que se pueden silenciar genes, a partir de ARN de doble cadena (ARNdc). Esta maquinaria se ha investigado para conocer su funcionamiento y buscar potenciales aplicaciones que podrían tener en el campo de la biotecnología. En varios estudios se encontró que el silenciamiento de genes se debe a las interacciones enzimáticas intracelulares citoplasmáticas con moléculas de ARN pequeñas (ARNsi), que actúan sobre el ARN mensajero (ARNm) intracelular, impidiendo que este se traduzca a proteína. Mediante este mecanismo se busca silenciar genes específicos en insectos plaga, que sean esenciales para que el insecto pueda vivir y de esa manera evitar la proliferación de la plaga. Este artículo recopila los estudios realizados acerca del ARN de interferencia, referidos al mecanismo genético de los insectos, como alternativa para su control.
Analyzing Errors in Students’ Subtitle Products

Subtitling has constraints that are different from other types of translation. In the pedagogical field, lecturers in subtitling courses must ensure that the students are aware of the constraints to creating a qualified subtitle. The constraints in subtitling frequently cause errors in the subtitles composed by the students. This article discusses the errors found in students’ subtitle products. The researchers took the subtitles of Miacademy Youtube channel videos composed by EFL students studying in one of the state universities in Central Java, Indonesia. Nine videos of Miacademy and their subtitles were analyzed to find the errors in the subtitles. The results revealed that the most frequent error is errors in spatial parameters, specifically on the excessive number of characters per line. The second most dominant error is the errors in the temporal parameter in which most of the students still found problems in obeying the rules of the maximum duration for either a full two-line or a single-line subtitle. Punctuation and letter case errors result from students’ lack of comprehension in mastering the target text language convention. Error in target text editing mainly occurs due to the too-long subtitles, segmentation that is not syntactically acceptable, the decision to omit or retain the source text, and the occurrence of dialect. Further analysis showed that the students need to practice adjusting their translation with the constraints. Likewise, a subtitling brief must be conducted before the lecturer delivers the task to the students by helping the students analyze the possible problems and solutions when composing the subtitles.
Washback Effects of English Reading Test in UTBK: Students’ Insights

Published: December 2022

Ujian Tulis Berbasis Komputer (UTBK) is a high-stakes test for students. They strive to pass the test and be accepted in their targeted institution. As one of the subjects involved in UTBK, the English test surely has influenced English teaching & learning in 12th-grade classrooms. This impact is known as the washback effect. While most studies investigate the washback effect on a test as a whole subject, little is known about the effect on the particular part of the test. Thus, this case study explores the washback effect of the English reading test in UTBK on the students’ perceptions, learning motivation, learning strategies, and learning content. The data were collected through online questionnaires distributed to six participants from different senior high schools. The deductive analysis found that the test has positive and negative effects seen from the students’ insights. UTBK can avoid cheating and integrate students’ English competence, but they are uncertain that it can improve their communicative competence. This study might enrich educational studies in English language teaching in general and language assessment in particular.

Translation is considered an essential element in the process of English learning. This descriptive qualitative study explores the translation ability and its influential factors performed by nine English club students of SMK Negeri 2 Surakarta in their debate class. Data were obtained by conducting a translation test. The students answered a questionnaire tested by the KR-20 formula to acknowledge the factors deeply. The results reveal that their ability to translate texts was good and excellent. Also, by using Microsoft Excel and interpreting using various theories in ELT, it was found that their ability was influenced by not only the external, internal, and individual factors but also their general learning strategies, way of learning vocabulary, teachers’ strategies in teaching grammar, and online tools as the part of learning media utilized by them. As translation becomes an inevitable process in ELT, these findings provide theoretical evidence that conducting TEFL by being attentive to the potential factors above and emphasizing the instructional designs is crucial. In addition, they directly influence the EFL learners’ translation ability, reflecting their English mastery and determining their success in the language learning process. Further, EFL teachers should pay more attention to their teaching strategy, consider allowing students access to online tools and motivate them to have a proper learning environment and reach optimal learning outcomes.
