Authors: Puspitasari Lintang Putri , Nugroho Abdillah
Published: July 2023

Stereotypes are viewed negatively since they indicate negative preconceptions about others. Hence, stereotypes are important to study because people might unknowingly employ stereotypes about others in regular encounters. Stereotypes are also found in many films, one of which is in the film "Freedom writer." The aims of this study are to analyze the categories of stereotypes that existed in the film Freedom Writer and to identify the functions of the stereotypes that are produced in the film. The researcher uses descriptive qualitative research. This research is a sociolinguistic approach of stereotypes occurring in the movie entitled Freedom Writers. The data is all utterances in the movie. The data analysis technique is carried out by employing sociolinguistics theory. The results of this study show that there are three categories of stereotypes occur: gender, race, and physical traits. The characters in Freedom Writers represent a diverse range of races, and their frequent interactions enable them to readily observe the different characteristics associated with their respective races. Consequently, due to the film's setting in a multicultural society, various stereotypes regarding race, with a particular emphasis on conflicts related to skin color, are prevalent. These stereotypes are influenced by cultural factors within this context.

Authors: Griffin Maureen A. , Hughes Kelly , Altwal Johnny , Seguin Bernard , Wustefeld-Janssens Brandan
Published: July 2023

OBJECTIVE

To determine the incidence of histologic grade shift (alteration of grade relative to the original tumor) in recurrent canine soft tissue sarcoma (STS) and mast cell tumor (MCT), and to determine the level of agreement between blinded pathologist review and original histology interpretation of STS and MCT grades.

ANIMALS

15 dogs with recurrent cutaneous/subcutaneous STS and 5 dogs with recurrent cutaneous MCT. All included dogs underwent excision of both the primary and recurrent tumors and had tumor samples available for review.

PROCEDURES

The medical records and histology database from a single institution were reviewed, and data were recorded and analyzed. A single board-certified veterinary pathologist performed blinded evaluation of all excisional tumor samples, including both primary and recurrent disease, and these were evaluated independently and in conjunction with initial pathologic diagnoses.

RESULTS

Based on single pathologist review, 7 of 15 (46.7%) dogs with recurrent STS had grade shift characterized by a higher or lower recurrent tumor grade in 4 of 7 and 3 of 7 cases, respectively, and 1 of 5 dogs with recurrent MCT had grade shift characterized by an increased grade of the recurrent tumor. Variability in reported grade between original histology report and pathologist review occurred for 13 of 30 (43.3%) STS excisional biopsy samples and 0 of 10 MCT excisional biopsy samples.

CLINICAL RELEVANCE

Grade shift has been reported in multiple tumor types in people and has the potential to alter prognosis and treatment recommendations. This is the first study to document this phenomenon in dogs. Additional large-scale studies are needed to determine factors associated with grade shift as well as prognostic significance of grade shift for recurrent canine STS and MCT.
Increased efficiency could lessen the need for more staff in companion animal practice
Authors: Ouedraogo Frederic B. , Weinstein Peter , Lefebvre Sandra L.
Published: July 2023

OBJECTIVE

To evaluate technical efficiency of US companion animal practices.

SAMPLE

60 independently owned companion animal practices selected from the 2022 AVMA Veterinary Practice Owners Survey.

PROCEDURES

A ratio of the weighted sum of outputs to weighted sum of inputs was computed for each practice (ie, decision-making unit [DMU]). Inputs included labor (hours worked) and capital (fixed costs and number of exam rooms). Outputs (or production) included annual gross revenue, number of patients seen per year, and number of appointment slots per full-time–equivalent (FTE) veterinarian per year. Data envelopment analysis was used to optimize the ratio and estimate relative efficiency (RE) scores.

RESULTS

25 (42%) practices were classified as having high efficiency (RE = 1 or 100% efficient), 26 (43%) as having moderate efficiency (RE > 0.7 but < 1.0), and 9 (15%) as having low efficiency (RE ≤ 0.7). Mean RE scores for moderate- and low-efficiency practices were 0.83 and 0.66, meaning they could have reached their current production levels with 17% or 34% less resources. Per the model, if all 60 practices were 100% efficient on the RE scale, 22 fewer FTE veterinarians, 47 fewer FTE veterinary technicians and assistants, and 43 fewer FTE nonmedical staff would be needed overall.

CLINICAL RELEVANCE

These preliminary findings suggested that efforts to optimize efficiency could allow companion animal practices to meet demands for their services without necessarily needing to hire more staff. Such efforts might include engaging support staff to their full potential and implementing automated processes. Additional research is needed to identify routines or workflows that distinguish high-efficiency practices from others.
The positive effect of the propaganda of family ethics and family education based on big data technology on the ideological work of youth
Authors: Li Na
Published: July 2023

Big data technology is gaining a lot of attention and research in the present day. In this article, based on big data technology, we use Spark’s big data hybrid computing model to promote family style and family education under the premise of large-scale information processing. The minimum average distance of all clusters is calculated by computing the mean and eigenvectors of the Hopkins statistic. The cohesiveness and separation of the contour coefficients on the clusters were evaluated based on the mean values. We also examine the error-squared and criterion functions and use this method to verify the positive effect of promoting family traditions and education on the minds of young people. In this paper, we get from the comparison experiment of mining algorithms: Spark algorithm mining efficiency is 200-300 higher than MR algorithm mining efficiency, and the mining efficiency is superior. Especially when the log volume is large, the efficiency enhancement effect is as high as 96.88%, which is conducive to creating a good ideological and political education environment for young people by further improving the positive role of propagating family style and family education in the ideological and political education of young people.

Authors: Wang Jun
Published: July 2023

Aiming at the influence of visual contextual information communication on industrial printmaking, this paper elaborates visual communication theory and establishes a visual information communication model after analyzing the concept, characteristics and components of visual communication, which has a role in visual contextual information communication. The four elements, three important links and the characteristics of visual communication in the process of visual communication are analyzed from the perspective of communication. Based on the above theories, a model of information communication in web interface is constructed. The computational process of the linear binocular cost aggregation algorithm is simplified by using the asymmetric cost aggregation method, and the more robust TAD matching cost function is used to compensate for the lack of accuracy caused by the simplification, and the computational process of the asymmetric linear cost aggregation algorithm is parallelized and mapped to the platform. Experimental data show that the asymmetric cost aggregation approach to linear binocular cost aggregation algorithm can obtain parallax maps in constant running time, and the quality of parallax maps is close to or better than some global matching algorithms which are at the forefront of research, and has a good prospect in the field of real-time binocular vision. The visual web pages designed by this method can better stimulate the user’s desire for acceptance, and the web pages have better visual communication effect and higher practical value, and can create better knowledge benefits in industrial printmaking, with an overall knowledge conversion rate of 85%.

Published: July 2023

Due to the diversified development trend of modern architectural design, the functional design and application of houses are being presented in the interior space color layout of houses with its many advantages of interactivity, comprehensiveness, multi-functionality, and personalization. With this as the starting point, this paper analyzes the psychological perception of survey respondents on the same spatial color through big data, converts the perception into EEG signal for decoding, and after the decoding process of EEG data pre-processing, feature extraction, feature identification, and classification, calculates the significance of each element in the time-frequency matrix, which can get a homo-dimensional mask matrix. Then the conditional random field model is established on the random field theory to get the parameters of the model. Finally, the parameters of the model are obtained by maximizing the following entropy function, which is brought into the Lagrangian operator to obtain the pairwise Lagrangian operator. Finally, the EEG signal is decoded to realize the self-control training of color perception under different mentalities. The experimental results showed that by performing the intervention test on self-control and color insight, the mean value of the total self-control score in training was 61.99±11.45, and the intervention effect had stability. Therefore, improving self-control ability and forming correct tendency psychological perception plays a vital role in the color design of architectural space.

An investigation into the practice of blended teaching in English courses based on the BOPPPS model
Authors: Guo Yulian
Published: July 2023

With the continuous development of information technology, the blended teaching mode is gradually and widely used in English teaching. Various online education platforms have emerged, most of which are student-oriented, through which teachers push various teaching resources to students in the form of text, audio, video, and other multimodal forms, mobilizing students’ visual, auditory and tactile senses to enhance students’ learning effect. It is an inevitable choice of the times for universities to use online resources, practice new education and teaching reform concepts, and constantly reflect on and reshape teaching modes. Because of the learning situation of English majors, teachers actively explore the blended teaching mode of English majors’ audio-visual courses, which helps students form good independent learning abilities and can effectively improve students’ comprehensive English application ability. However, during the initial practice, the disadvantages of blended teaching in English audio-visual courses are highlighted, which are reflected in the lack of Internet teaching resources, poor teacher and student autonomy, and an imperfect teaching evaluation system. With the help of information technology, the BOPPPS teaching model is rapidly and highly integrated with traditional English audio-visual course teaching. Based on the BOPPPS model, this paper combines the background and meaning of blended teaching in English major audiovisual speaking courses with four aspects of practical investigation: constructing a resource base, teachers’ knowledge management ability, students’ self-learning ability, and teaching evaluation system.

The results of the teaching experiment show that under the improved teaching mode of the BOPPPS model, students’ English IV exam scores improved by 13.85%, and self-learning ability improved by 21.25% compared with the control group after a period of study, which verifies the feasibility of the hybrid teaching of the BOPPPS model and promotes the convergence of English education with the international level.
Synergistic effect of acetic acid and NOXfor objects made of lead and its alloys; indoor corrosive environments in museums and depositories
Authors: Majtás D. , Mácová P. , Adámková I. , Viani A.
Published: July 2023

Complex corrosion simulation to evaluate synergistic effect have to cover large number of factors. To do so, environmental and corrosion datasets collected by monitoring sites of interest have been used to tailor complex artificial ageing of lead and lead alloys, using lead, tin and tin-lead coupons. Material composition was based on objects of interest which are tin-lead alloy based although naming lead objects is used widespread for vast of them. To evaluate results corrosion rate based on weight loss, phase composition of corrosion product and colour change of the coupon surface were utilized. For thin corrosion layers formed micro Raman and FTIR did not provide suitable results, and GIXRD have been used.

Although limited number of conditions were used for the simulations, synergistic effect was observed for lead under specific conditions. Synergistic effect do occur on lead when exposed to NOX and acetic acid fumes of relatively low concentrations (18 µg·m-3 and 500 ppb respectively).

In addition, there is grouping of colourimetric data collected according to test regimes – phase composition of corrosion product respectively. This information albeit preliminary suggests that colourimetric spectroscopy may be suitable as fast and easy corrosion monitoring.

Published: July 2023

The OBJECTIVE was to evaluate the role of mean perfusion pressure in the development of acute kidney injury (AKI) in patients operated with CPB.

METHODS AND MATERIALS. A retrospective monocenter observational study was conducted among patients CPB (n=97) who underwent planned heart surgery using CPB. Inclusion criteria: age over 18 years, duration of surgery from 90 to 180 minutes, no signs of end-stage renal disease. The group was divided into subgroups according to the level of mean perfusion pressure (MPP): 1st – MPP<60 mmHg, 2nd – MPP equal to and >60 mmHg. Diagnosis of AKI was carried out on the basis of changes in serum creatinine and biomarkers (NGAL, IgG, albumin in urine). The studied parameters were recorded 15 minutes after the start and end of general anesthesia as well as 24 and 48 hours after surgery.

RESULTS. In the 1st subgroup, the frequency of AKI was higher: after 24 hours – 48 (78.7 %), in the 2nd subgroup – 10 (27.8 %), and after 48 hours – 21 (34.4 %) and 5 (13.9 %), respectively. In the 1st subgroup, the need for renal replacement therapy was 5 (8.2 %), while in the 2nd subgroup only 1 patient needed renal replacement therapy (2.8 %). Also, in the 1st subgroup, a higher level of lactate was detected at the end of general anesthesia – the median in the 1st subgroup was 4.6 mmol/l (2.5–11.6), in the 2nd – 2.5 mmol/l (1.4–7.2) (p= 0.022). The levels of AKI biomarkers in urine after 24 hours also differed: NGAL in the 1st – 473.1 ng/ml (235.7–749.5) and in the 2nd –111.3 ng/ ml (53.4–152.9) (p=0.003), albumin 174.6 mg/l (151.2–236.9) and 35.8 mg/l (21.3–52.5) respectively (p=0.006), IgG – 61.7 mg/l (24.9–88.5) and 9.7 mg/l (7.1–14.4) (p=0.002).

CONCLUSION. Mean perfusion pressure is an important indicator of the adequacy of cardiopulmonary bypass. Lowering it below 60 mmHg leads to hypoperfusion of the kidneys with the risk of acute kidney injury.

Published: July 2023

Background: The emergency department (ED) is a healthcare environment where patients are treated for various conditions. The Triage system is a tool used to prioritize patients based on the urgency associated with their cases. A recognition of the triage system increases satisfaction, whereas long time waiting is associated with poor patient outcomes. There needs to be more literature regarding public awareness outside of the COVID era; thus, we aim to provide data on general population awareness of the triage system used in ED in Saudi Arabia.
Methods: A cross-sectional study was conducted in Saudi Arabia from July 2022 to January 2023. The selection of sampling was made by convenience sampling, and data were obtained from an online questionnaire.
Results: The study included 650 participants. 60% of them were females, and 40% were males. 54.6% of participants know that there is a medical triage system in emergency departments, which is considered a low percentage, as 45.4% did not know about the triage system in emergency departments, which would negatively affect patient satisfaction. In addition, 63.4% of study participants did not know that there are urgent care centers that provide treatment outside of emergency departments, and 47.4% did not know that health centers or urgent care centers can treat most emergency cases.
Conclusion: The general Saudi population is unaware of emergency department triage systems. There should be an effort to spread awareness of the triage system. In addition, developing further training and education in emergency department triage to address knowledge deficits and incorrect triage beliefs is critical.

Quantitative Structure-Property Relationships (QSPR) to Predict Surface Tension and Electrical Conductivity of Ionic Liquid Propellants
Authors: Yos Daniel , Chambreau Steven D. , Sengupta Debasis , Newsome David A. , Vaghjiani Ghanshyam L.
Published: July 2023

Quantitative structure property relationships (QSPR) mine data sets of experimentally measured properties to predict different material properties through mathematical regression and machine learning. QSPR have the capability to predict any property, as long as there is a large enough data set of measured values. It is often costly and time-consuming to experimentally test certain properties of ionic liquids, and modern fundamental theoretical (quantum chemical or molecular dynamics) approaches require significant computer resources and may have limited accuracy. On the other hand, QSPR allow for simulations to converge to a result in just a few hours. These simulations are reliable, fast, and accurate, and only require a small number of input parameters. In this work, we predict surface tension and electrical conductivity values of potential ionic liquid propellants via QSPR, and present a detailed discussion on the error analysis performed on the results obtained.
Emerging Materials and Design Principles for Wurtzite-type Ferroelectrics

Published: July 2023

The energy demand for computing and data storage will continue to rise exponentially unless non-traditional computing architectures and innovative storage solutions are explored. Low-energy computing, including compute-in-memory architectures, has the potential to address these energy and environmental challenges and, in particular, tetrahedral (wurtzite-type) ferroelectrics are promising options for both performance and integration with existing semiconductor processes. The AlScN alloy is among the few tetrahedral materials that exhibit ferroelectric switching, but the electric field required to switch the polarization i.e., the coercive field, E_c, is on the order of MV/cm, which is about 1–2 orders of magnitude higher than more traditional oxide perovskite ferroelectrics (E_c < 100 kV/cm). Instead of further engineering AlScN and related alloys, we explore the alternative route of computationally identifying new materials with switching barriers lower than AlN while still possessing high enough intrinsic breakdown fields. Going beyond binary compounds, we explore the search space of multinary compounds with wurtzite-type structures. Through this large-scale search, we identify four promising ternary nitrides and oxides, including Mg2PN3, MgSiN2, Li2SiO3, and Li2GeO3, for future experimental realization and engineering. In > 90% of the considered multinary materials, we identify unique switching pathways and non-polar structures that are distinct from the commonly assumed switching mechanism in AlN-based materials. Our results disprove the existing design principle based on reduction of wurtzite c/a lattice parameter ratio while supporting two emerging design principles – ionicity and bond strength.
Aerosol emissions from Heated Tobacco Products: a review focusing on carbonyls, analytical methods and experimental quality
Authors: Sussman Roberto A. , Sipala Federica , Emma Rosalia , Ronsisvalle Simone
Published: July 2023

We provide an extensive review of 17 independent industry-funded studies targeting carbonyls in aerosol emissions of Heated Tobacco Products (HTPs), focusing on quality criteria based on the reproducibility of experiments, appropriate analytic methods, and puffing regimes. Most revised studies complied with these requirements, but some were unreproducible, and others failed to consider analytical variables that may have affected the results and/or produced unrealistic comparisons. We also provide a review of the literature on physicochemical properties of heated tobacco and HTP aerosols, as well as the evaluation of HTPs by regulatory agencies and address various critiques of their relative safety profile. The outcomes from the revised studies and regu-latory evaluations tend to agree with and converge to a general consensus that HTP aerosols ex-pose users to significantly lower levels of toxicity than tobacco smoke.

DNA change (HG38)(protein change) 20:g.2859771TC ENST00000380445.8:c.106TC ENSP00000369810.3:p.Cys36Arg. The patient's disease began quite late, in the 4th decade of life, with spastic torticollis. Subsequently, the spread of the pathological process involving the muscles of the neck, the right upper limb, then the right lower limb, myoclonia of the right hand and tremor of the right lower limb was noted. Secondary mitochondrial disorders were revealed in the form of an increase in the level of lactate in the blood before and after loading with carbohydrates. A decrease in the activity of mitochondrial enzymes in peripheral blood lymphocytes was also revealed: succinate dehydrogenase, an enzyme of the mitochondrial respiratory chain complex II; -glycerophosphate dehydrogenase involved in mitochondrial fat metabolism; glutamate dehydrogenase (amino acid metabolism in mitochondria). The level of lactate dehydrogenase in peripheral blood lymphocytes in the patient was elevated. The identified secondary mitochondrial disorders may be an indication for the appointment of energotropic medicines along with levodopa drugs and dopaminergic receptor agonists. In the presented observation, it can be argued about autosomal dominant inheritance, since the patient has a characteristic clinical picture of the disease and a mutation in the heterozygous state in the VPS16 gene was detected.

Background. Ischemic stroke (IS) and cerebral microbleeds (CMB) are the most common types of neurological complications of infective endocarditis (IE), while their combination is poorly understood.
Aim. To evaluate the pattern of combination of cortical-subcortical infarction with lobar CMB or subarachnoid hemorrhage (SAH) in patients with left-sided IE.
Materials and methods. A retrospective case-control study was conducted, including patients with IE who received cardiac surgery at the Federal Center for Cardiovascular Surgery. Inclusion criteria: age of patients 18 years; definite or possible (Duke criteria) IE of the left heart (aortic and/or mitral valves). The control group included patients without IE, with non-lacunar (likely embolic) IS. In both groups, the pattern of combination of cortical-subcortical infarction with lobar CMB or SAH was assessed. Differences between groups of patients were assessed using the 2 test, Fisher's exact test and the MannWhitney test. Additionally, odds ratios for binary features were calculated. To assess the information content of the studied pattern, classical classification quality metrics were calculated: accuracy, sensitivity, and specificity.
Results. In patients with IS, infarcts corresponded to the main characteristics of cardioembolism: involvement of multiple cerebral arterial territories (84%), multiple infarcts (88%), cortical-subcortical localization (100%), and a high incidence of hemorrhagic transformation (44%). CMB was detected in 64% of cases (in 93.8%, CMB localization was lobar), SAH in 28% of patients (with CMB in 6 out of 7 cases). The pattern of combination of cortical-subcortical infarction with lobar CMB or SAH was observed in 64% in the IE group (in the control group in 12%). Odds ratio for the presence of IE was 13.0 (95% confidence interval 3.0455.9; p0.001). The accuracy of the sign was 76%, specificity 71%, sensitivity 84%.
Conclusion. The combination of cortical-subcortical infarcts with lobar CMB or SAH may be a sign characteristic of IE-associated stroke.

The economic damage accompanying the fire blight is expressed both in the loss of crops and in the costs associated with uprooting of infected trees and restoration of fruit plantations.  Pear is characterized the highest rates of susceptibility to fire blight. Development of genetically resistant cultivars is one of the crucial aspects of managing fire blight, which would allow foregoing the current economically or ecologically unsound methods such as removal of infected plants or application of antibiotics on the early stages of development. In this research, a five-year monitoring of the distribution of fire blight was performed among a collection of pear cultivars growing in a pomological garden. The cultivars ‘Ajdana’ and ‘Kirgizskaya zimnyaya’ showed the highest resistance to E. amylovora according to the results of field inspections. The infection occasions for every cultivar were confirmed by direct or indirect PCR. ‘Ajdana’ and ‘Kirgizskaya zimnyaya’ bear alleles of fire blight resistance for the CH02F06 marker, and ‘Kirgizskaya zimnyaya’ additionaly carries the resistance allele for the TsuENH017 marker. ‘Talgarskaya krasavica’ and ‘Lesnaya Krasavitsa’ are susceptible cultivars to fire blight, but at the same time their genomes include the resistance alleles for the CH02F06 marker.

In recent years, the study of microstrip patch antennas has witnessed significant advancements, offering numerous advantages and promising prospects compared with conventional antennas. These antennas are characterized by their lightweight compact size, low cost, low profile, small dimensions, and excellent conformability. Additionally, microstrip patch antennas exhibit various desirable features, such as dual and circular polarization, dual-frequency operation, broad bandwidth, flexible feedline configurations, and beam-scanning omnidirectional patterns. In this paper, a microstrip patch antenna design tailored for the 2.4 GHz frequency band is proposed, showcasing its potential for applications in wireless communication devices. The antenna is engineered to operate across multiple bands, including the wireless device band, Ultra Wide Band (UWB), and X band. It has a truncated rectangle shape with additional stubs, whereas the substrate material employed is FR4. The resulting design achieves resonance at four different frequencies, effectively covering the Microwave Access (WiMAX) band at 2.5 GHz and 4 GHz. Notably, the implementation of Digital Global Systems (DGS) plays a crucial role in reducing the antenna size while simultaneously enhancing its performance. The proposed microstrip patch antenna demonstrates great potential for meeting the increasing demand of modern wireless communication devices. Its multiband operation, compact size, and improved performance, achieved through the integration of DGS, make it a promising candidate for various wireless communication applications.

The article cites the need for a reliable and economical power supply to rural consumers. At the same time, it is important to develop distributed generation, including on the basis of renewable sources, using solar and wind energy to reduce costs. The necessity of choosing solar panels with optimal parameters, taking into account the influence of external factors, is shown. To determine the actual generated power of solar batteries, the concept of "power loss during the conversion of the solar radiation flux into electrical power" is introduced. It has been established that insufficient studies of the regime parameters of photocells, in particular, the temperature of its heating and the corresponding change in efficiency, taking into account external factors, do not allow choosing a module with effective power. To study the parameters of solar batteries, an equivalent circuit and methods for determining its parameters are presented. The established dependence of the excess of the SM temperature over the ambient temperature on the power of solar radiation is presented, which formed the basis of an improved method for determining the parameters of solar batteries. The presented results of the study allow at the design stages to determine the expected power of a solar photovoltaic installation and choose its optimal parameters.

Published: July 2023

El presente estudio evaluó los efectos de la cocción (hervido y al vapor) sobre el contenido de compuestos fenólicos totales (CFT), la capacidad antioxidante determinada por DPPH y ORAC y la inhibición de la formación de óxido nítrico (NO) y peroxinitrito (ONOO-) de quintonil. Los CFT aumentaron durante la cocción al vapor en 10.2 veces. Los valores de DPPH oscilaron entre 284.7 y 3014.0 µmol ET/g, para ORAC se mostraron valores de 123.1, 318.6 y 3228.5 µmol TE/100 g para quintonil crudo, hervido y al vapor, respectivamente. La capacidad para neutralizar al NO varió ente un 10.55 al 83% y los valores de ONOO no fueron afectados por los tratamientos de cocción. Se observó que la cocción al vapor produce una mayor liberación de compuestos fenólicos y una mayor actividad antioxidante del quintonil. Los tratamientos de cocción demostraron liberar más compuestos fenólicos debido a la destrucción de las estructuras celulares; aunque también puede ocurrir la liberación de enzimas oxidativas que pueden inactivar los compuestos fenólicos. La cocción al vapor parece desactivar mayoritariamente a estas enzimas evitando que ocurra la pérdida de los compuestos fenólicos.
