Visual Teaching System Design of University Political Video Course Based on Network Node Algorithm

With the continuous development of wireless sensor networks in the fields of industrial measurement and control, medical monitoring, and intelligent buildings, the demand for network performance is also increasing. Conventional MAC protocols used in wireless sensor networks can no longer meet the low power consumption, interference suppression, high reliability, and high throughput communication requirements of these applications. With the changes in related visual media in education, from wood boards and cards in the age of visual media to slides and projections in the age of audio-visual media, as well as the extensive development of various visual tools, visual teaching systems are all in terms of technology, environment, mode, and meaning. Visual education research in the development of video courses first needs to understand the educational function of the smart classroom, including the related concepts, research progress, and key functions of the smart classroom. At the same time, it is also necessary to clarify the theoretical principles and expression methods of video course development and their effectiveness in professional training. Finally, we can combine the advantages of the two educational institutions to design applied research and apply it to visual education in smart classrooms. This is exactly where the educational philosophy of the university political curriculum of visualized higher education policy plays an important role in running the university political curriculum of higher education policy. In the context of multiculturalism, how to deal with the new problems and new situations of the current ideals and concepts of college students, how to grasp the main problems, and how to solve the problems are a topic worthy of continuous discussion and summary.
The Relationship Between Ferritin and BMI is Mediated by Inflammation Among Women in Higher-Income Countries, But Not in Most Lower-Income Countries Nor Among Young Children: A Multi-Country Analysis

ABSTRACT Background In the presence of inflammation, the serum or plasma ferritin concentration (“ferritin” hereafter) transiently increases, confounding its interpretation as an iron status marker. The extent to which adiposity-related inflammation may influence ferritin interpretation is uncertain. Objectives We describe relationships between weight status, inflammation, and ferritin among nonpregnant women of reproductive age (WRA; 15–49 years) and preschool-age children (PSC; 6–59 months) with normal weight to overweight or obesity (OWOB) in differing geographic settings. Methods Cross-sectional data were separately analyzed from 18 surveys (WRA) and 25 surveys (PSC) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project, excluding observations with underweight, wasting, pregnancy, or malaria. Relationships were assessed between BMI (in WRA) or BMI-for-age z-score (BAZ; in PSC), inflammatory biomarkers of C-reactive protein (CRP) and/or α-1-acid glycoprotein (AGP), ferritin by linear regression, and potential mediation by CRP and/or AGP in relationships between BMI or BAZ and ferritin with structural equation modeling. Regression and mediation models accounted for complex survey designs. Results were grouped by World Bank income classifications. Results In 5 of 6 surveys among WRA from upper-middle and high-income countries, ferritin was significantly positively associated with BMI, and this relationship was partially (or fully, in the United States) mediated by CRP and/or AGP. Mediation was present in 4 of 12 surveys for WRA in low- and lower-middle income countries. Among PSC, ferritin was positively associated with CRP and/or AGP in all surveys, but there were no significant CRP- or AGP-mediated relationships between ferritin and BAZ, except a negative relationship in the Philippines. Conclusions Where having OWOB is common among WRA, measurements of inflammatory biomarkers and their uses in interpreting ferritin may improve iron status assessments. While these relationships were inconsistent among PSC, inflammation was common and should be measured to interpret iron status. Included Kenyan trial data are registered at clinicaltrials.gov as NCT01088958.
The Antibacterial Activities of Lavandula angustifolia L., Mentha piperita L., and Ribes nigrum L. against Oral Bacteria, and Their Antioxidant Activities

There is an expanding interest in medicinal and aromatic plants as a natural alternative to synthetic drugs, especially to antimicrobial agents due to the growing problem of antibiotic resistance. In recent years, a lot of reports have been published on the antimicrobial activity of the plant extracts. This study was used Lavandula angustifolia L. , Mentha piperita L. , and Ribes nigrum L. as plant materials. This study aims to test the plant extracts against oral bacteria. Its purpose is to produce directly comparable, quantitative, antimicrobial data, and in addition to containing very little information of the different extracts against oral pathogens. Disc diffusion method was studied for antimicrobial activity tests. Also, minimum inhibitory concentration (MIC) values were determined in this study. Additionally, the extracts were tested against stable 2,2-diphenyl-1-picryl-hydrazyl-hydrate• (DPPH•) free radicals for non-enzymatic antioxidant activity. This study was used Trolox (6-hydroxy-2,5,7,8-tetra-methyl chroman-2-carboxylic acid) as standard. The extracts showed different inhibition zones against bacteria. The methanol extract of Lavandula showed the highest inhibition zone against the oral pathogen MBKK5. The positive control was penicillin (10 μg). The lowest MIC value was taken at 6500 μg /ml concentration of the plant extracts. The highest DPPH• radical scavenging activity was found in Ribes nigrum extract as 36%. As a result, plant extracts have antibacterial and antioxidant potential.
Effects of Different Salt Applications on Ion and Physiological Analysis in Lettuce

The increase in salinization in agricultural lands adversely affects crop production. In particular, yield and quality losses occur in many vegetables such as lettuce, which are grown and consumed in every season. Realizing these losses in crop production, more careful fertilization and agricultural practices should be done. Yedikule lettuce seeds were used in the study to draw attention to these negative aspects. The study, which was carried out for two years, was designed with 0, 50, 100 and 150 mmol doses of salt according to a randomized parcel design with three replications and four pots in each replicate. Each 2-liter pot was filled with a 2:1 ratio of peat: perlite mixture and the study was carried out with 2 lettuces in each pot. As a result of the study, when the plant weight data of the first year and the second year are examined, it is seen that the weight loss of lettuce plants and damage to the plants increase when the salt doses increase. It was observed that the highest plant weight loss occurred at 150 mmol salt dose. Membrane damage index in lettuce leaves was observed to increase as the salt dose increased. It was observed that the leaf water rate decreased with increasing salt doses. Membrane damage index and leaf water content of lettuce plants were more negatively affected at 150 mmol of salt in both years. Potassium, calcium and magnesium contents in lettuce leaves were statistically decreased due to increasing salt doses in both years, while sodium content increased with increasing salt doses and the highest sodium content was observed at 150 mmol dose in both years. As seen in these results, increasing salt doses reduce the nutrient content and plant weight in lettuce plants and cause physiological damage to the plant, resulting in yield and quality loss.
Symmetric key chaotic image encryption using circle map

The security of information and digital images has become a major issue during the last three decades. A large number of algorithms for data and image encryptions are reported in the literature. However, many of the proposed algorithms are not suitable in the fields of application, because they are cryptographically weak. In the present work, a novel algorithm for encoding digital images by using a circle map with 3 parameters has been proposed. In this article different images are used for testing the validity of the proposed algorithm. The algorithm has increased the strength of security of the image encryption against cipher-text-only, chosen-plaintext and chosen-cipher-text attacks. The analysis of cryptographic strength has also been performed to confirm the fact. The results of several experimental tests, such as, key space analysis, key sensitivity analysis and statistical analysis show that the proposed algorithm for image cryptosystems provides an efficient and secure way for image encryption. A comparison in terms of correlation between the initial and transformed images, number of pixels change rate (NPCR) and unified average changing intensity (UACI) is also done.
Sentinel Lymph Node Mapping with Indirect Lymphangiography for Canine Mast Cell Tumour

Simple Summary Mast cell tumour (MCT) is a common cutaneous and subcutaneous neoplasia in dogs. Recent studies describe that sentinel lymph node (SLN) assessment is more specific to stage MCT, while regional lymph node (RLN) evaluation is not as specific. SNL is the first site of drainage of a tumour and the first metastatic site in several tumours. The study aims to evaluate the SLN drainage mapping of MCT with indirect lymphography in dogs. The second objective of the study is to compare the SLN to the RLN. Survey radiographs followed by an indirect lymphography were obtained for SLN mapping. Twenty-six dogs with 29 MCTs were included. SLNs were detectable in 26 MCTs and radiographic indirect lymphangiography with Lipiodol was able to detect at least one SLN in 90% of MCTs in dogs. In conclusion, radiographic indirect lymphangiography with Lipiodol is a feasible technique to map SLNs and its draining system in MCTs. The lymph drainage pattern of the MCTs may be different for each MCT and more than one SLN can be involved. Abstract Mast cell tumour (MCT) is a common cutaneous and subcutaneous neoplasia in dogs. It can metastasise to lymph nodes (LNs), and this adversely affects the prognosis and treatment. The study aims to evaluate the SLN mapping of MCTs with radiographic indirect lymphography. Dogs that underwent clinical staging were prospectively enrolled. Lipiodol was injected around the MCT or the surgical scar. After 24 h, LNs that picked up contrast were radiographically assessed. Twenty-six dogs with 29 MCTs were included. MCTs were confirmed histologically, while SLNs were evaluated either by cytology and/or histology. SLNs were detectable in 23 dogs with 26 MCTs. Lymphatic vessels were visible in 19 MCTs. In nine MCTs, at least two SLNs picked up contrast. In particular, seven MCTs involved two SLNs, and two MCTs involved three different SLNs. In nine MCTs, at least a SLN was metastatic. This study indicates that the lymph drainage pattern of the MCTs may be different for each MCT, and more than one SLN can be involved. Indirect lymphangiography with Lipiodol allowed the detection of the SLN in 90% of MCTs. This provided clinically relevant information to remove the LN and stage the patient.
Peritoneal dialysis for acute kidney injury: back on the front-line

ABSTRACT Peritoneal dialysis (PD) for acute kidney injury (AKI) has been available for nearly 80 years and has been through periods of use and disuse largely determined by availability of other modalities of kidney replacement therapy and the relative enthusiasm of clinicians. In the past 10 years there has been a resurgence in the use of acute PD globally, facilitated by promotion of PD for AKI in lower resource countries by nephrology organizations effected through the Saving Young Lives program and collaborations with the World Health Organisation, the development of guidelines standardizing prescribing practices and finally the COVID-19 pandemic. This review highlights the history of PD for AKI and looks at misconceptions about efficacy as well as the available evidence demonstrating that acute PD is a safe and lifesaving therapy with comparable outcomes to other modalities of treatment.
Understanding doctoral progress assessment in the arts and humanities

This study examines the early-stage progress assessment for doctoral candidates at a British university through the perceptions of academic staff who acted as assessors. It was conducted in response to staff concerns about changes to the process that shortened the timescale for candidates to prepare and present their research for peer review. As well as having an impact on doctoral supervisors, there were implications for researcher developers and ‘third space’ professionals who supported candidates with research skills training. The findings of four in-depth interviews with assessors in the arts and humanities are discussed in the form of a reflective, ‘structured debriefing’. The results of these reflections form recommendations for practice that highlight the importance of conceptual frameworks for doctoral assessment, and the interpretations of criteria at institutional, disciplinary and individual levels. These could be emphasised by academic supervisors and third space professionals supporting doctoral candidates through this milestone.
Grading Teacher Performance Appraisal Systems: Understanding the Implications of Student Test Scores and Performance Information Use

Abstract Accountability and performance management scholars have called for more attention to the micro-level consequences of performance regimes, including the effects of performance information use. Reflecting these themes, this study considers the degree to which accountability regimes in schools, imposed by U.S. states, and encouraged by the federal government, relate to teachers’ job satisfaction and turnover intentions. Using data from the 2015 to 2016 National Teacher and Principal Survey, we consider the degree to which the following relate to teacher attitudes: (1) the inclusion of student achievement growth on standardized tests in teacher performance appraisals, (2) using additional sources of performance information in the appraisal beyond the student achievement scores, and (3) the differential effects of developmental and administrative uses of appraisal ratings. Our results show that when schools include student growth on standardized tests in appraisals, teachers report lower satisfaction and a higher turnover intention. Using additional sources of performance information, however, relates to improved satisfaction and decreased turnover intentions. Using student standardized test information to inform both positive and negative administrative consequences is associated with lower satisfaction but is not associated with turnover intentions.
Comparison between Physical Parameters and Sensory Parameters Regarding Travel Behavior Based on Sensitivity Analysis

An effective way to optimize decision-making regarding the transport mode choice in the transportation system is improving or changing the travel cost, the travel time, or some other travel characteristics by using sensitivity analysis. This method encourages travelers to switch from private transportation to public transport, thus reducing pollution and emission. Furthermore, by searching for the most sensitive factors in travel behavior, the sensitivity analysis might highlight the directions of the improvement. However, according to previous studies, travelers will transfer from one transport mode to another only if the utility of the new choice is higher than the original transport mode. In the current paper, sensitivity analysis is applied to provide a comparison between the impacts of the physical and sensory parameters on the travel behavior and transport mode choice based on a utility function. The multinomial logit (MNL) model is used to estimate and perform the sensitivity analysis of the main variables. The sensitivity analysis demonstrates the degree of the travelers’ sensitivity to changes in the travel characteristics including both physical and sensory parameters. The models are calibrated with the NLOGIT software and validated through statistical indicators; thus, the essential factors influencing the choices are obtained. The input variables selected for the models are based on the data collected in Budapest, Hungary. The sensitivity analysis is determined by the outputs of the variables based on the changes of the input variables. As the results show, the travelers have more sensitivity to the changes in the physical parameters. Furthermore, the outcomes indicate that the travel cost is an essential variable, which greatly affects the decisions related to the transport mode choice. From the sensory parameters, the comfort factor has more influence than other factors. The results of the analysis present that the travelers’ sensitivity to changes in the travel utilities of the travel characteristics impacts the decisions regarding the mode choice behavior significantly.
Breaking the Limits of Display and Fabrication using Perception-aware Optimizations

Novel display devices and fabrication techniques enable highly tangible ways of creating, experiencing, and interacting with digital content. The capabilities offered by these new output devices, such as virtual and augmented reality head-mounted displays and new multi-material 3D printers, make them real game-changers in many ﬁelds. At the same time, the new possibilities offered by these devices impose many challenges for content creation techniques regarding quality and computational efﬁciency. This paper discusses the concept of perception-aware optimizations, which incorporate insights from human perception into computational methods to optimize content according to the capabilities of different output devices, e.g., displays, 3D printers, and requirements of the human sensory system. As demonstrated in this paper, the key advantage of such strategies is that tailoring computation to perceptually-relevant aspects of the content often reduces the computational cost related to the content creation or overcomes certain limitations of output devices. Besides discussing the general concept, the paper presents several speciﬁc applications where perception-aware optimization has been proven beneﬁcial. The examples include meth-ods for optimizing visual content for novel display devices that focus on perceived quality and new computational fabrication techniques for manufacturing objects that look and feel like real ones.
Association between Student’s Food Habit, Physical Activity and BMI: A Study in Khulna University

The research work was conducted on 150 undergraduate and postgraduate students who belonged to the Social Science School of Khulna University. Purposive sampling was followed to select the participants and a semi-structured questionnaire was used in the study to collect data in accordance with the survey research method. The present study shows the association between students’ body mass index and its covariates via bivariate analysis (Fisher's exact tests). Study results indicate that respondents' physical exercise status (p>.02) and sleeping habits (p>.04) were significantly associated with their body mass index. On the other hand, personal attributes and food habits had no association with their body mass index. Moreover, the author suggested that nutritional education programs should be provided by the university for the students which inspire them to pursue a healthy lifestyle.
Tipología de consumidores de miel con educación universitaria en México

México es un país productor de miel, paradójicamente, su consumo per cápita es bajo comparado con los países europeos. El objetivo fue realizar una tipología a consumidores de miel en México con nivel educativo mínimo de licenciatura en edades de 20 a 60 años y determinar sus características socioeconómicas y aspectos que motivan el consumo. Se aplicó un cuestionario a una muestra de 1,003 consumidores de miel que cumplieran con las condiciones de edad y nivel escolar. La información se analizó mediante análisis de conglomerados y discriminante. Se identificaron tres tipos de consumidores: 1) consumidores educados con ingresos promedio (34.4 %), fueron los que consumen miel frecuentemente, tienen un amplio conocimiento sobre los subproductos de la apicultura y propiedades de la miel, prefieren comprar el producto con los apicultores; 2) consumidores altamente educados con ingresos altos (25.8 %), en su mayoría tienen posgrado y reciben ingresos mayores a $5,000 semanales, fueron personas en edad madura y con consumo moderado de miel, una tercera parte de este grupo solo conocen la miel, tienen conocimiento de sus propiedades y cualidades, les es indiferente el lugar de compra; y 3) consumidores educados con ingreso bajo (39.8 %), agrupó a consumidores jóvenes que solo tienen nivel de licenciatura, su consumo es moderado, prefieren comprar el producto en mercados. Los grupos de consumidores conformados brindan información sobre un segmento del mercado de la miel en México, es necesario continuar realizando investigaciones sobre temas referentes a consumo y preferencia de los consumidores de miel en México.
Boundary Value Problems for a Family of Domains in the Sierpinski Gasket

For a family of domains in the Sierpinski gasket, we study harmonic functions of finite energy, characterizing them in terms of their boundary values, and study their normal derivatives on the boundary. We characterize those domains for which there is an extension operator for functions of finite energy. We give an explicit construction of the Green's function for these domains.
De seriebus divergentibus

Euler gives a long introduction, giving all the arguments for and against the use of divergent series in calculus and then gives his own definition of the sum of a diverging series. Then in the second half of this paper he evaluates the the 1-1+2-6+24-120+720-. on several ways and gets the sum 0.5963473621372. The paper is translated from Euler's Latin original into German.
Healthcare Professionals' Experiences with Rehabilitation Practices for Patients with Cognitive Impairment after Stroke in North Norway: A Qualitative Study

Methods A focus group interview with clinicians, coordinators, and leaders involved in stroke survivors' rehabilitation trajectories was conducted. The group consisted of a strategic selection of participants with diverse professional backgrounds from specialist and primary healthcare services. The transcribed material was analyzed thematically using systematic text condensation based on an inductive, interpretive approach. Results We found that patients with mild and moderate cognitive impairment after stroke were characterized as a neglected group in rehabilitation services and that neglect was related to both structural and professional issues. First, neglect seemed partly related to the availability of existing healthcare services, which mainly followed up on physical challenges after stroke. Second, cognitive rehabilitation seemed to be less prioritized than other health services, and the established interdisciplinary municipality teams did not seem prepared to follow-up on cognitive issues. Finally, at a professional level, the study reveals the need for building competence in cognitive rehabilitation and having services available in the long run. Conclusion The study demonstrates the need to increase knowledge concerning cognitive rehabilitation and how rehabilitation trajectories and services should be organized to fulfil stroke survivors' and carers' long-term needs.
