Authors: Hou Wenwen , Zhang Lihong , Agarwal Ravi P. , Wang Guotao
Published: March 2021

This paper first introduces a generalized fractional p-Laplacian operator (–Δ)sF;p. By using the direct method of moving planes, with the help of two lemmas, namely decay at infinity and narrow region principle involving the generalized fractional p-Laplacian, we study the monotonicity and radial symmetry of positive solutions of a generalized fractional p-Laplacian equation with negative power. In addition, a similar conclusion is also given for a generalized Hénon-type nonlinear fractional p-Laplacian equation.

In this paper, we used high-resolution IR absorption spectra to investigate 1D and 2D polaritons in periodical 2D macroporous silicon structures with nano-coatings of SiO2 and CdS, ZnO nanoparticles. The application of high-resolution IR absorption spectroscopy resulted in detection of dipole-active TO vibrations, photon splitting and giant two-polar absorption oscillations with amplitudes of ±107arb.un. As a result, the dispersion law in yz surfaces of macropores change to z direction along macropores. It means additional degree of freedom as vertically polarized light in z direction and horizontally polarized light in x direction resulted in beams splitting and two-photon interference - Hong-Ou-Mandel effect. In our case, 2D resonances of Wannier-Stark electro-optical effect in yz plane correspond to constructive interference of the two-photon states (bosonic behavior), and two-polar resonances in ±z direction are determined by destructive interference of the two-photon states (fermionic behavior). Two-polar oscillations of 1D -polaritons have the ultra-small half-width 0.4–0.6 сm–1 and minimal Rabi frequency of samples 1.0 сm–1 equaled to the resolution of spectral measurements. Furthermore, two-photon interference and 1D polaritons are perspective for high-coherent optical quantum computers on macroporous silicon with nano-coatings and, in addition, for lasers and new metamaterials.

Authors:   Chuiko Institute of Surface Chemistry of National Academy of Sciences of Ukraine, Belyakova L. A.
Published: March 2021

The encapsulation of medicinal substances in various polymers is a common way to increase their thermal, hydrolytic, and chemical stability. However, the bioavailability of the encapsulated drugs decreases. The solution to this important problem can be the preparation of nanocapsules of medicinal substances using complexing agents, for example, cyclodextrins. The purpose of this work is to study the possibility of encapsulation of benzoic, salicylic, and β-resorcylic acids using α- and β-cyclodextrins. The interaction of benzene carboxylic acids with cyclodextrins in aqueous solutions at 20–30 оС has been studied by spectrophotometry. The formation of complexes with a composition of 1:1 in the cyclodextrin – benzene carboxylic acid systems has been proven. The stability constants of the complexes and the main thermodynamic parameters of complex formation have been calculated. It has been shown that the nature of changes in the spectral characteristics of benzene carboxylic acids in the presence of cyclodextrins can be used to predict the possibility of aromatic organic compounds encapsulation. The determining role of the complementarity of geometric parameters of cyclodextrins and benzene carboxylic acids in the preparation of inclusion complexes with features of nanocapsules has been found. The prospects of using β-cyclodextrin for encapsulation of benzene carboxylic acids have been demonstrated. The complexes of β-cyclodextrin with benzene carboxylic acids were synthesized and studied by IR spectroscopy, X-ray analysis and derivatography. The formation of two types of complexes in the β-cyclodextrin – benzene carboxylic acid system was established. The first type of complexes is formed due to nonspecific interactions between the hydrophobic cavity of β-cyclodextrin and the benzene carboxylic acid molecule, the second type is due to specific interactions between the functional groups of molecules. Benzoic and salicylic acids form nanocapsules with β-cyclodextrin, and their hydrolytic and thermal stability increases. Complexes of the second type acquire the properties of a new compound: β-resorcylic acid loses its individuality, forming strong supramolecular structures with β-cyclodextrin.

For improve the quality of harvests, modern farms in many countries widely use fertilizers of mineral and natural origin. To mitigate the negative impact on the environment, they try to minimize the amount of mineral fertilizers applied to the soil by creating composite systems. In particular, powdered composite materials are known based on highly dispersed silica and microquantities of mineral fertilizers, which are applied to the surface of the seeds by dusting. The aim of this work was to develop a new generation of film stimulating coatings based on mixtures of hydrophobic AM-1-300 and hydrophilic A-300 silicas, mineral fertilizers and bioactive components. Mixtures of hydrophilic and hydrophobic silicas in the ratio 1:1 and 1:2 were used to obtain a pasty composite with the given stimulating properties; colloidal starch solution; medium salts of mineral acids, bioactive components “Humifriend” and fungicide “Fital”. Such composite systems were applied directly to the surface of sowing material, grains of wheat variety “Natalka” before sowing in sand and on filter paper, according to DSTU 4138-2002. During the study, the following parameters were measured: seed germination energy, germination and morphological characteristics of wheat germs, which consisted in measuring the length of the root and stem. It is shown that when editing certain amounts of bioactive components to the composition of stimulating pasty composites, it is possible to program the properties of future films and powders: to increase morphological characteristics, uniformity of germination and fungicidal characteristics of composites. It has been found that the presence of mineral fertilizers in pasty composites of silicas mixtures 1:1 and 1:2 has a positive effect on the uniform germination of wheat seeds in the sand and on the filter paper. Instead, the presence in the pastes of the active ingredients “Fital” and “Humifriend”, regardless of the environment where the seeds germinated, there is a significant slowdown in the growth of wheat germ in both environments. It has been found that an excess of hydrophilic silica in the pasty composite leads to the development on the surface of the grains of mycosis lesions, regardless of the germination environment. Therefore, stimulant pastes based on 1:2 silica mixtures must contain fungicides of mineral or biological origin.

Authors: Pfaff Nora , Pantell Matthew S. , Kaiser Sunitha V.
Published: March 2021

BACKGROUND AND OBJECTIVES:

Risky behaviors are the main threats to adolescents’ health. Consequently, guidelines recommend adolescents be screened annually for high-risk behaviors. Our objectives were to (1) determine rates of physician-documented risk behavior screening of hospitalized adolescents, (2) determine rates of positive screening results, and (3) evaluate associations between risk behavior screening and provision of risk behavior–related health care interventions.

METHODS:

We conducted a cross-sectional study of patients aged 12 to 24 years admitted to the pediatric hospital medicine service at an urban tertiary children’s hospital from January to December 2018. Exclusion criteria were transfer to a different service, nonverbal status, or altered mental status. We reviewed 20 charts per month. Outcomes included (1) documentation of risk behavior screening (mood, sexual activity, substance use, abuse and/or violence, and suicidal ideation), and (2) risk behavior–related health care interventions (eg, testing for sexually transmitted infections). We determined associations between screening and risk behavior–related interventions using χ2 tests.

RESULTS:

We found that 38% (90 of 240) of adolescents had any documented risk behavior screening, 15% (37 of 240) had screening in 4 of 5 risk behavior domains, and 2% (5 of 240) had screening in all 5 domains. The majority of screened adolescents had a positive screening result (66%), and most with positive results received a risk behavior–related health care intervention (64%–100% across domains). Adolescents with documented screening were significantly more likely to receive a risk behavior–related health care intervention.

CONCLUSIONS:

We found low rates of risk behavior screening documentation among hospitalized adolescents. There was a high rate of positive screen results, and those who were documented as screened were more likely to receive risk behavior–related interventions.

Detection of animal mixtures in meatballs by using Fourier Transform Infrared Spectroscopy (FTIR spectroscopy) has been studied. This research aims to study the different markers of fat characters in meatballs containing the mixture of chicken fat, lard and rat fat. Sample preparation used Soxhlet extraction with n-hexane solvent and distillation of fat from the solvent. The extraction temperature is 70°C with solvent volume 200 mL. Fat samples were prepared by varying the ratio of 100% chicken fat concentration which corresponds to 1%, 10%, and 20% lard, and 1%, 10%, and 20% rat fat. The meatballs were made with a composition of 0%, 5% and 90% rat meat. The result of FTIR interpretation shows that the increasing concentration of the mixture of lard and rat fat have increased the absorption at wave numbers of 3371 cm-1, 3332 cm-1, 2337 cm-1, and 1743 cm-1. The FTIR spectrum is interpreted based on the uptake of typical functional groups of animal fats. The characteristics of animal fat properties can be distinguished by consistent results using infrared spectroscopy.
THE PROBLEMS AND COUNTERMEASURES OF BRINGING COLLEGE SPORTS RESOURCES INTO THE PUBLIC SERVICE SYSTEM OF NATIONAL FITNESS IN THE NEW ERA
Authors: Ma Zhonglin
Published: March 2021

ABSTRACT With the deepening of the national health program, the number of people participating in sports activities is increasing, and the problem of insufficient community sports resources is becoming more and more obvious. It is an effective way of solving the problem of injecting sports resources into the public service system of national fitness, but the process of integration of sports resources and public national fitness service is not smooth. Through expert consultation and a fuzzy comprehensive evaluation method, this study analyzed the current situation of university sports resources into the public service system of national fitness, and collected the evaluation of social fitness personnel on the opening of university resources by means of a questionnaire combined with experts' opinions, using a fuzzy comprehensive evaluation method to transform subjective and fuzzy evaluation into objective and specific evaluation points. The research shows that the current level of university sports resources into the public service system of national fitness is low, which shows that the sports resources sharing policy under the national fitness has not been well implemented. The study proposes that the level of sharing of sports resources can be strengthened by the awareness of sharing of sports resources by university leaders and improving the management system. This study is expected to represent a reference for the university sports resources into the public service system of national fitness in the new era.
THE CONSTRUCTION OF A PROFESSIONAL MODEL OF PHYSICAL EDUCATION TEACHERS IN COLLEGES AND UNIVERSITIES FROM THE PERSPECTIVE OF PUBLIC HEALTH SERVICE
Authors: Shan Dan
Published: March 2021

ABSTRACT With the continuous improvement of people's material living standards, public health and national fitness has become a social topic, and has been widely concerned by the public, in terms of the traditional physical education and impact of the concept of health. This not only needs the school to carry on the multi-directional adjustment to the physical education teaching, but also needs the physical education teacher to respond positively to this in order to adapt to the development needs of the times and society. This study uses the analytic hierarchy process (AHP) to construct the professionalization model of physical education teachers in Colleges and Universities, and makes decision on the index weight of the model through fuzzy comprehensive evaluation. The results show that the weight of the first-class indicators of P.E. Teachers' professionalization model from large to small is ability > quality > knowledge, and the consistency ratio (CR) of the model indicators is less than 0.1, and the fuzzy score of the model is 85 points. Therefore, the model of P.E. Teachers' professionalization constructed in this study has consistent indicators and shows good applicability. This does not only provide the basis for the professional development evaluation of College PE teachers, but also provides research ideas for the development of the sports industry from the perspective of public health.

Published: March 2021

ABSTRACT Enhancing the physical health of college students is the fundamental guarantee of cultivating high-quality talents. In order to understand the influencing factors of college students' physical health and carry out targeted intervention, this study aims to analyze the factors affecting college students' physical health. Through the construction of physical health evaluation index and its influencing factors evaluation index, the importance of different indicators is evaluated by using the analytic hierarchy process, and a questionnaire about college students' physical health and its influencing factors is designed. The results show that the factors affecting college students' physical health include students' own factors, school factors, and others. At the same time, the insufficient construction of public sports facilities and the lack of first-class sports venues and equipment are also the reasons for the decline of college students' physique. Therefore, we can intervene in the students' physical health from the aspects of raising the students' awareness about physical exercise and Ensuring the construction of school sports facilities. It is hoped that this study can provide some reference for the empirical analysis and intervention research on the influencing factors of college students' physical health.

Authors: Liang Rizhong
Published: March 2021

ABSTRACT With the improvement of the quality of life, the residents’ requirements for the construction of urban public sports services have gradually improved. In order to improve the current urban public sports service system, this study analyzes the existing public sports service through the construction of public sports service model. The results show that the current construction of public sports service has some defects, such as single construction subject, unbalanced regional development of sports service, lack of perfect performance evaluation mechanism of sports public service, and so on. Therefore, in the process of public sports service construction, we need to pay attention to the diversification of construction subjects, the cultivation of residents’ awareness of physical exercise, the improvement of performance evaluation mechanisms of sports public services, and the broadening of investment channels. These measures can improve the urban public sports service system from the perspective of public health, and create better quality public sports services. This study analyzes the problems existing in the construction of public sports service by building a model, and puts forward some suggestions for improvement, hoping to provide ideas for scholars who study related experiments.

Resumo Objetivo Comparar a percepção de estudantes de enfermagem e as contribuições do ensino com simulação clínica ou aula prática convencional em laboratório de habilidades, na primeira experiência clínica hospitalar. Método Pesquisa descritiva, qualitativa, envolvendo estudantes de graduação em enfermagem de uma universidade pública do Brasil, submetidos à simulação clínica de alta fidelidade ou aula prática convencional, ocorrida entre 2015 e 2016. Para avaliação dos dados, utilizaram-se a nuvem de palavras e a análise de similitude do software IRAMUTEQ®. Resultados Participaram 54 estudantes, sendo 27 em cada grupo. As palavras mais evocadas pelo grupo simulação foram: “paciente real, não, mais e simulador”, relacionadas à capacidade de reflexão quanto ao seu conhecimento e preparo. As mais evocadas no grupo prática convencional foram: “mais, não, muito e sentir”, relacionadas com a percepção de que a aula convencional ajuda na aquisição de habilidades, contudo, é necessária maior frequência. Conclusão As duas estratégias contribuíram positivamente para a primeira experiência clínica hospitalar. Porém, a simulação proporcionou uma visão crítico-reflexiva sobre as competências, deficiências e maior autoconfiança em relação à prática convencional. Este estudo fortalece as evidências dos benefícios proporcionados pelo ensino baseado em simulação, e a importância de instituições de ensino fazerem uso adequado dessa estratégia.

Introduction: Dentomaxillary Anomalies (DMA) affect the growth and morphology of the stomatognathic system of individuals, representing a public health problem. Few studies have described its prevalence among vulnerable populations in Chile. The aim of the study was to explore the prevalence of DMA and its association to non-physiological habits (NFH) and sociodemographic characteristics among primary school children living in Ercilla, Chile. Material and Methods: A convenience sample of 327 primary school students from six schools in Ercilla, were assessed through an intraoral and extraoral evaluation. Overjet, overbite, molar relationship, presence of DMAs, and NFHs were measured. Descriptive statistics, analysis of association between DMAs and studied factors, and logistic regression models were done and odds ratio with 95% confidence intervals presented. Results: A total of 61.5% of students presented at least one DMA. Chi-square test showed no significant association between DMA prevalence and NHFs, however, after adjusting for sociodemographic factors, children with NFH were 1.69 (95%CI 1.02-2.78) times more likely to have DMAs. Gender and area of residence were not significantly associated with DMAs. Conclusion: In children from Ercilla, DMAs were associated with NFHs, however, sociodemographic characteristics did not have a significant role in the presence of DMA, suggesting that sociodemographic factors might not strongly influence orthodontic needs among children from this geographical area.

Approaches to Registration of a Color as a Trademark under Civil Law with Respect to Light Industry Products
Authors: Dorofeeva A. M.
Published: March 2021

Difficulties in registering a color as a trademark arise for many reasons. The author questions the existence of a distinguishing ability of a color sufficient for a trademark to perform its function serving as a means of individualization, as well as its functionality and capability to be presented in graphic form. Due to the strongest visual component, it is in the light industry where there is the greatest demand for registration of colors as trademarks. Thus, the light industry is rich in examples of registration, as well as attempts to register, such designations. Most representative examples are the red color of the sole of Christian Louboutin shoes and turquoise color associated with Tiffany & Co. At the same time, in Russia there is no normative basis, judicial practice, or doctrinal studies that would allow us to develop the principles of determining the existence of discernible ability of color or approaches to their establishment. Thus, the paper relies broadly on the legislative and enforcement experience of foreign legal systems that allow us to trace the different logic of compliance of color symbols with trademark criteria, as well as limits for establishing rights to color symbols, which can be useful for adapting best practices in our country.

Published: March 2021

The world has been exposed to the Coronavirus Disease 2019 (COVID-19) since late 2019. A global pandemic has shifted health concerns from air pollution effects to novel coronavirus disease, similarly to those in Bangkok. Although Bangkokians have experienced severe PM2.5 conditions since the last quarter of 2017, the related agencies have failed to elucidate the crisis. This has been because the fundamental air quality management is focused on controlling emissions. The Thai government has sluggishly determined the situations that lead to the inability to clean up its air. How are air pollution and disease linked? This article points to the importance of source management. The lockdown measures revealed reduced traffic rate and PM2.5 concentrations. Such a close relationship has shed insights of the consequences of working from home (WFH). The link between disease and air pollution includes (i) WFH regulation is one specific way to prevent the transmission of disease, (ii) this guideline decreases traffic congestion in an urban city which is one path of diminished pollution discharge and (iii) then noticeably followed by PM2.5 reductions. Again, the magnitude of source control is crucial. Reducing pollutions from traffic by means of WFH has illustrated this accomplishment. In the midst of this crisis, moving to a new normal role supports remaining protected from both air pollution and the pandemic. Nevertheless, the sustainability of transportation control in an overcrowded city like Bangkok should be considered as a vital pathway to tackle air pollution.

San Francisco de Paula. Origen y relaciones de un rancho fundado por afrodescendientes en el Yucatán independiente
Authors: Victoria Ojeda Jorge
Published: March 2021

El objetivo del texto es esclarecer en lo posible el origen de los primeros pobladores del rancho San Francisco de Paula y demostrar el contacto que tuvo con San Fernando Aké, ambos sitios fundados por afrodescendientes. Se propone que sus primeros moradores llegaron de Cuba en 1823. La investigación está basada principalmente en fuentes primarias. Los resultados sacan a la luz las desconocidas interrelaciones entre los afrodescendientes que vivían en las periferias circuncaribeñas y la región yucateca. La información sobre el asentamiento constituye una aportación a la historia regional por la temporalidad del suceso, por la coyuntura política de su arribo y por los contactos posteriores. La historia del poblado siguió, aparentemente sin mayor notoriedad, el mismo sendero que las restantes comunidades yucatecas, mientras las autoridades y la prensa locales se encargaban de silenciar el pasado y el presente de los africanos y afrodescendientes

Like in every part of the world, COVID-19 was the main issue in Indonesia during 2020. The main problem in the community is that they consider the COVID-19 pandemic to be an ordinary situation, resulting in a lack of awareness. This study aimed to produce a short film about COVID-19 and find out its effectiveness in delivering messages regarding the implementation of the COVID-19 health protocol. The research protocol consists of two stages. The first is the pre-research stage, which discusses the use of title themes, and the second is the research stage, which discusses content for design objects. The study produced two short films that discuss two things that are part of the preventive measures, such as the usage of masks and hand sanitizers. Both films represent a group of people who often experience disinformation due to low literacy rate.

Authors: Novitasar Nine Febrie , Nurfiqih David
Published: March 2021

Some Indonesian elementary schools include English as a local content subject. However, one aspect that is often missing in the process of teaching and learning is supporting teaching media. This is often found in schools based in remote areas, including the one at SD Negeri 6 Tambak Ukir, which is included in this study. The teaching and learning at this school is not fully accommodated because of the unavailability of teaching media. The students are not fortunate enough to afford commercial learning media. The problems worsen with the fact that the teachers have never been professionally prepared and trained to teach English. Such problems lead to meaningless learning. Concerning the issues, we developed five big books to be used by English teachers and students of SD Negeri 6 Tambak Ukir with the aim to provide supplementary learning media for the students, particularly in learning English vocabulary. The research adopted the development model proposed by Gall, Gall, and Borg (2003). There are four simplified stages in this development process: problem analysis, product development, product trials, and product revisions. In the first stage, the researchers planned to develop 10 books, but because of the COVID-19 pandemic situation, only five books (including a manual user) could be developed. The topic covers numbers, colours, alphabets, animals, and the human body. The provision of the books helped the teachers in delivering the topics. The books could also create a new learning experience for the students. Besides, the students also felt that they could get closer to their friends because they could learn together and felt extra motivated. In other words, having been validated and tried out, the books were proven to be valid, effective, and practical. They were valid as they were developed based on strong theories, effective as they can fulfil students’ needs, and practical as they can facilitate both teachers and students during the teaching and learning process. Briefly, the big book can describe itself well. It is big, bold, and beautiful with impacts.

Authors: Wahyuningtyas Tri
Published: March 2021

This study describes the power and knowledge and the relationship between the two of the puppeteers of the mask puppet show in Malang district. This qualitative research used interviews and observation to collect data, which were then analysed using the Foucault’s genealogical method. The results showed that the puppeteers of the mask puppet show in Malang have a more substantial knowledge orientation than other puppeteers. The puppeteers have obtained their power–knowledge by disciplining their bodies for several years, built from its social and environmental existence. The role of a puppeteer requires a person to not only have spiritual strength but also a vision of directing and organising the show. The puppeteer’s power-knowledge produces discourse that has autonomy and power.

Utilizing the Quranic Arabic Corpus as a Supplementary Teaching and Learning Material for Arabic Syntax: An Overview of a Web-based Arabic Linguistics Corpus
Authors: Arifianto Muhammad Lukman
Published: March 2021

This article discusses the plan to implement the Quranic Arabic Corpus for the development of Arabic syntax teaching and learning materials (TLM), especially at the university level. The study explores an alternative Arabic syntax TLM development by utilizing a corpus, one of the most important linguistic research resources. In recent years, corpora have been widely utilized in developing teaching materials. The Quranic Arabic Corpus is beneficial not just in terms of additional references or examples, but also in facilitating grammatical understanding and discussion. The highly adequate syntactic annotations recorded in this corpus can also be used to discover and explore the syntactic analysis of every word in the Quran, so that it can be easily implemented in the analysis, examples of each chapter, or section of the discussions in Arabic syntax. Based on the analysis of this corpus’s content and its relevance with the existing Arabic syntax teaching materials, it is shown that this corpus can be incorporated as a supplement of Arabic syntax TLM. The following six steps should be followed to utilize this corpus in Arabic Syntax learning: (1) prepare the necessary tools, (2) select learning materials, (3) determine keywords, (4) access QAC, (5) search for keywords in QAC, and (6) select search results and proceed with the syntactic analysis.

Metacognition Strategy for the Development of Basic Thinking Competency in Preliminary School Textbooks
Authors: Nurchasanah . , Suyono . , Omar Noritah , Habsari Zakia
Published: March 2021

For humans, thinking and producing language are two inseparable activities. They often take place together, such as in language production or in speaking. Furthermore, thinking has different levels, from basic level thinking (literal) to higher-order thinking (critical-creative). A basic level of thinking competencies can be improved to higher order thinking competencies. Besides, metacognition is essential as it becomes the controller to improve the achievement of basic level competencies. Nevertheless, the metacognition element of literal competence has not yet been known until today, especially in elementary school (sd) thematic textbooks. Therefore, this study aims to describe the metacognition strategies of developing literal thinking competencies in elementary school textbooks at the beginning level (grades 1 and 2). This qualitative study employs the content analysis method. The research data is in the form of a discourse that represents a strategy for developing literal thinking competencies in an elementary thematic textbook based on the 2013 curriculum published by the ministry of education and culture, the 2017 revision. The data were collected using a documentation technique with a key instrument designed by the researcher complemented with other instruments: the blueprints of research implementation, data collection guidelines, and data analysis guidelines. The data were analyzed in the following sequence: presenting raw data, data reduction, data analysis, concluding the results, interpreting the results, and presenting the results. The validity of the data and the results of the study were checked through triangulation and re-analysis. The results revealed that literal competencies of observing, identifying, remembering, imitating, and composing were developed through metacognition strategies in the form of (1) invitations, (2) invitations followed by orders, and (3) invitations followed by orders—questions/questions—orders.
