Geriatric dizziness
Authors: Ha Sam Yeol
Published: June 2023

The prevalence of vertigo and dizziness in the elderly is rapidly increasing due to aging of population. The presence of dizziness in the aged may be connected to falls, which is the leading cause of accidental death in older people. The geriatric dizziness may manifest differently, as patients tend to report less rotatory vertigo and more non-specific and complex dizziness than younger patients. The understanding of pathophysiology in the geriatric dizziness and systematic approach for this symptom help a clinician to find proper management. In this review, we present age-related degenerative changes in nervous system and diagnostic and therapeutic approaches focusing on the elderly patients with dizziness.

Authors: Cao Kai , Zhao Yingying
Published: June 2023

Social security-oriented rental housing is not only an important way to solve the housing problem for urban residents, but also an effective means to improve the quality of urban life and promote sustainable development of urban environment. Past public rental housing emphasized efficiency in construction, allocation, and use, but lacked public functionality, resulting in many projects becoming identical "miniature commercial housing". Therefore, this article focuses on the "two-type" security-oriented rental housing and lists new design cases of Modern rental housing. It proposes that social security-oriented rental housing should enjoy multiple rights and have the aesthetic function of open shared space and personalized innovation, low-carbon emission reduction intelligent function, fair transfer and participation function. Measures such as providing preferential housing, rental or new housing subsidies, and land price subsidies are provided for specific populations in need. By realizing the design concept of multiple values, social security-oriented rental housing can not only maintain basic rights, but also enhance the quality of residents' lives, further improving their quality of life and environmental friendliness.

Authors: Bao David
Published: June 2023

The Chinese Porcelain art burgeoned during the Song Dynasty, particularly under emperor Huizong’s rule. Within the era, the official kiln was known for its exquisite quality and the fascinating philosophical thoughts underpinning the art pieces’ unique aesthetic features. This paper analyzes and portrays the aesthetic outlooks of the official kilns, examining the philosophy, form, textures, colors, production details, and the influences of the art. Sources of the analysis will be derived from different literature, including Mandarin and Western. The findings of this paper suggest that the Celadon art, particularly the official kiln, is an art form that stems from the particular political situation of the Song era, with the art form’s development comprised of the combined intellectual thoughts of the Song artists and literati. In addition, not only has the official kilns evolved from its previous art forms, which originated as early as the Han Dynasty but also carried on its influences on future art forms even until the modern period.
Analysis of the Influence of Academic Anxiety and Family Capital on Students’ Academic Performance from the Perspective of Peer Effect in China
Authors: Wang Yihe
Published: June 2023

In the context of the serious phenomenon of "in-rolling" in China's education sector and the inequality of educational resources, this paper examines the prevalence of academic anxiety and the influence of cohort and family capital on academic performance through a questionnaire survey of young people in Beijing, Tianjin and Hunan. Based on the research method of correlation and regression analysis, the degree of influence and the mechanism of action are explored. Based on the results, it was found that peers had a significant positive effect on students' own academic performance, while academic anxiety and other exogenous variables such as family capital had less significant effects. The analysis of the data suggests that the causes of academic anxiety come from a variety of sources and that exogenous factors such as family economic and cultural capital have become less influential on academic achievement as society develops and young people's thinking improves; changing peers is perhaps the most effective way to intervene on student achievement.

Published: June 2023

The pneumonia epidemic caused by the new coronavirus is spreading around the world, and the national epidemic situation is complicated and severe. At the same time, in order to implement the guidance of the Ministry of Education during the period of prevention and control of the new coronavirus epidemic, "suspend classes without teaching, and without stopping learning". Computer technology has played a huge role in the absence of on-site and offline surveys. Our group generated electronic questionnaires through computer technology, successfully digitized paper surveys, and adopted rigorous survey methods. Through Sina Weibo, WeChat, Tencent QQ Share and complete the questionnaire with the students, strictly review the IP address, and eliminate the invalid answer sheet, there are 600 valid questionnaires in total. Finally, the computer data analysis software-spss is used to clean and analyze the data, and finally obtain the analysis results of the sample data, and also ensure the authenticity of the survey results. Prior to this, we adopted an exact proportion of single and double selection questions and subjective question types. Through comparative analysis and cross-analysis, the interference of huge data on the later survey results was greatly reduced, and the accuracy of the survey was ensured. Based on this, it is believed that the online teaching platform should establish a rich knowledge database to provide students with some resources outside the classroom, which can mobilize students' interest in learning, and at the same time, it should have a more complete evaluation system, so as not to increase students' inertia. Furthermore, since it is an efficient and fast teaching method, it should not be used by some people, but more or all teachers should be familiar with and adapt to this teaching mode as soon as possible.

Authors: Ma Ziqing
Published: June 2023

In the modern society with the rapid development of Internet technology, the Internet penetration rate is growing rapidly, and the number of young Internet users is also increasing. However, while the Internet brings convenience to young people, there are also many hidden dangers. In recent years, the act of indecency against children on the Internet has often been exposed in social news, causing widespread public concern, and even many parents of children have panic. At present, there are no clear laws, regulations and judicial interpretations to define it in China, and it is only mentioned in the gist of a few guiding cases. Many related cases involving the act of indecent assault on children in cyberspace have also exposed the shortcomings of its identification in judicial practice. Therefore, it is necessary to further improve the identification of the act of indecent assault on children in cyberspace on the basis of guiding cases. This paper screens and analyzes the existing relevant judicial cases, and summarizes the aspects to be solved in practice. The viewpoint of this paper is based on the theory of "four elements of crime constitution" commonly used in Chinese legal academia, which enriches the understanding and application of the legal interests, objective and subjective aspects of the crime of child molestation in cyberspace.

Authors: Li Tianyu
Published: June 2023

The reform of corporate compliance is rapidly unfolding in pilot regions, as it holds significant importance not only for the governance and prevention of corporate crimes but also for incentivizing companies to initiate compliance measures. To effectively harness the incentives of corporate compliance, the key lies in the identification of appropriate incentive targets. However, in the current judicial practice in China, there are challenges related to the identification of incentive targets, such as a lack of clarity in the scope of identification, ambiguity in the criteria for identification, and deficiencies in the identification process. Therefore, it is necessary to clarify the scope of identifying incentive targets for corporate compliance, define the criteria for their identification, and improve the process of identifying such targets. By maximizing the incentive effects of corporate compliance, we can promote the steady development of compliance reform in our country.

Published: June 2023

Objective: To monitor the incidence of BK virus infection in hematuria of renal transplant recipients induced by different immunizations.Methods: A total of 109 patients who underwent renal transplantation in Baogang Hospital of Inner Mongolia from January 2019 to December 2022 were analyzed retrospectively. The results of BK virus DNA detection in urine and blood were observed after operation. They were divided into three groups according to different immunosuppressive induction regimens; 35 patients in group A, 42 patients in group B, and 32 patients in group C (basiliximab). To explore the effect of different immune induction regimens on BK virus infection in renal transplant recipients.Results: The positive rate of urine BK virus in all patients in 1 month after operation was 10.09% (11/109), which was significantly higher than that of blood BK virus 0% (0/109), and the difference had a statistical significance (p < .05). The positive rate of urine BK virus in all patients in 6 months after operation was 31.19% (34/109), which was significantly higher than that of blood BK virus 3.67% (4/109), and the difference had a statistical significance (p < .05). The positive rate of urine BK virus in all patients in 12 months after operation was 35.79% (39/109), which was significantly higher than that of blood BK virus 5.50% (6/109), and the difference had a statistical significance (p < .05). The urinary BK virus infection rate was increased significantly from 1 month to 6 months after operation, but was not increased significantly from 6 months to 12 months after operation. There was a statistically significant difference between the two groups (p < .05). The BK virus infection rate in renal transplant recipients induced by basiliximab within the first month was significantly lower than that in patients using polyclonal antibodies, but the urinary BK virus infection rate after one year was not significantly different from that in patients using polyclonal antibodies.Conclusions: There are slight differences in BK virus infection after early renal transplantation with different immune induction therapies, but there is no significant difference in the long-term. It is recommended to strengthen the early monitoring of BK virus after renal transplantation, timely adjust  immunosuppressive regimens to achieve the early detection and early treatment.

Students Approaches to Learning: Towards a Context-specific Learning Approaches Instrument
Authors: Madeleine Kapinga-Mutatayi , Pierre Mukendi waMpoyi , Elen Jan
Published: June 2023

Students' Approaches to Learning (SAL) are a critical determinant of learning outcomes and have been assessed around the world, from Asia to Africa, using the traditional questionnaires developed in the Western context. However, studies in Asia have challenged the traditional dichotomous view of SAL by supporting the presence of intermediate approaches, suggesting that the current view of SAL may not be universal. In response to the need for a broader understanding of SAL, a new instrument, the Approaches to Learning Questionnaire (ALQ), was developed during a pilot study. This instrument captures both memorization and understanding in an African context, which makes it distinct from traditional instruments. Additionally, the ALQ challenges the current individualistic view of SAL by including a group dimension. Given the high psychometric quality of this new instrument, it is crucial to validate it with a large sample. Therefore, this paper discusses the validation processes and recommends the use of the ALQ for comparative purposes in the Congolese context. Further research will explore the extension of this context-specific instrument to other cultural settings and the assessment of cross-cultural validity.

Purpose. The purpose of this study was to determine and compare visual quality indicators in eyes wearing multifocal center-distance, and dual-focus soft contact lenses that are speciﬁcally designed for the purpose of myopia progression management, as well as single-vision soft contact lenses. Material and Methods. Visual quality indicators of 34 eyes of healthy, young myopic adults ages 20 to 35 were determined. Non-cycloplegic measurements were conducted without contact lenses (baseline) and while subjects wore soft multi- focal center-distance soft contact lenses (ArtMost SoftOK SMR and SEED 1-day Pure UP Multistage daily disposable), dual-focus soft contact lenses (CooperVision MiSight 1 Day), and single-vision soft contact lenses (iLens Aqua Bi-weekly). In this study, the lenses were referred to as SoftOK, Pure UP, MiSight, and iLens. The measured and analyzed visual quality indicators included high-contrast distance and near visual acuity, stereopsis, accommodative amplitude, accommo- dative response, spherical aberration, and horizontal coma. Results. High-contrast distance and near visual acuities, accommodative responses, and stereopsis values achieved with the SoftOK, Pure UP, and MiSight contact lenses werecomparable to those achieved with the iLens single-vision soft contact lenses and to baseline values. Accommodative amplitude was slightly reduced with the MiSight contact lens and spherical aberration was signiﬁcantly higher with the SoftOK lens compared to the other lenses. Both ﬁndings had statistical signiﬁcance (P = 0.047 and P < 0.001, respec- tively). Horizontal coma, most likely resulting from slight lens decentration, was higher and more variable with the SoftOK lens compared to the other lenses, although no statistical signiﬁcance was determined. Conclusion. Dual-focus and multifocal center-distance soft contact lenses allow for good visual quality, especially clear vision at distance and near. Small diﬀerences in accommoda- tive amplitude and spherical aberration were found between lens designs, however the clinical impact requires further investigation.

Authors: Liedtke Fernanda Soubhia , Garcia Alessandro Perussi , Zotarelli Filho Idiberto José
Published: June 2023

Introduction: In the liposculpture scenario, and at the cellular and molecular level, tissue engineering has numerous advantages that meet the needs of the injured tissue or organ for the regeneration process or fillings and contours. Biological microenvironments enable cell recognition and signaling cascades for neovascularization and stabilization of fat grafting. Objective: A concise systematic review was carried out on the use of potential biostimulators (cells and molecules) and the biochemical and physiological mechanisms that can contribute to the successful process of cervicofacial liposculpture, to promote neovascularization and stabilization of fat grafting or fat reduction. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from February to April 2022 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 96 articles were found. A total of 36 articles were fully evaluated and 34 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 11 studies at high risk of bias and 37 studies that did not meet the GRADE. The present study showed that the use of potential bio stimulators such as stromal vascular fraction cells and mesenchymal stem cells from adipose tissue, exosomes, microRNA, and PRP, as well as the molecules secreted by these cells, can contribute to the successful process of cervicofacial liposculpture, to promote neovascularization and stabilization of fat grafting or fat reduction. Furthermore, studies have shown that the use of adipose tissue plus PRP led to the presence of more pronounced inflammatory infiltrates and greater vascular reactivity, increased vascular permeability, and certain reactivity of the nervous component, noting that the addition of 20% PRP activated with calcium to adipose tissue grafts can enhance the results of regenerative and aesthetic facial surgeries.

Introduction: In the context of bucco-maxillo facial surgery, the development of biomaterials for use in clinical dentistry in recent years has represented a powerful therapeutic instrument in the correction of bone defects. Adult tissue stem cells (mesenchymal stem cells) mediate homeostasis and regeneration of tissues and organs. Growing evidence suggests that metabolism during quiescence, activation, and differentiation may vary between tissues, integrating signaling cues and metabolic inputs with the release of exosomes and microRNAs as important metabolic messengers. Objective: It was to carry out a systematic review to present the main considerations and scientific evidence of the cellular and molecular mechanisms of bone formation or regeneration through mesenchymal stem cells, exosomes, and microRNAs in the scenario of bucco-maxillo-facial surgery with bone graft or biomaterials. Methods: The systematic review rules of the PRISMA Platform were followed. The search was carried out from March to May 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, with articles dated 2001 (gold standard) through 2022. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed accordingly, according to the Cochrane instrument. Results and Conclusion: A total of 145 articles were found, 45 articles were evaluated and 34 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 30 studies with a high risk of bias and 15 studies that did not meet GRADE. The greater potential of guided bone regeneration was associated with the graft material due to the higher grade of vital bone and the lower percentage of residual graft particles. Inorganic bovine bone and porcine bone minerals combined with autogenous maxillary cortical bone showed similar biological and radiological characteristics in terms of biomaterial resorption, osteoconduction, and osteogenesis when used for maxillary sinus floor augmentation. In this regard, three fundamental parameters in bone tissue engineering that determine the capacity for osteoinduction were evidenced, such as the presence of soluble osteoinductive signals, the viability of undifferentiated mesenchymal stem cells, having the ability to differentiate into bone-forming cells and production of adequate extracellular matrix. The exosomes that contain proteins, mRNAs, microRNAs, and DNAs stand out. Exosomes change the biochemical characteristics of recipient cells through the delivery of biomolecules and play a role in cell communication. Evidence suggests that exosomes derived from mesenchymal stem cells exhibit functions similar to mesenchymal stem cells with low immunogenicity and without tumorization.

A pastagem constitui um dos alicerces na produção de carne e o seu adequado manejo se torna substancial na garantia de excelência da atividade. O adequado crescimento da gramínea forrageira está diretamente relacionado às propriedades físicas e químicas do solo em que é cultivada. Mediante isto, o presente estudo aborda sobre características produtivas e estruturais de Brachiaria ssp. em Latossolo Vermelho-Amarelo. Os resultados foram obtidos por meio de análise de experimento realizado no município de Guaraí-TO, com plantio de 10 parcelas de capins do gênero Brachiaria. Foram analisados resultados de massa seca total, massa seca de lâmina foliar, massa seca de colmo, massa seca de material morto, proporção de lâmina foliar, proporção de folha/colmo e densidade populacional de perfilho para as forrageiras em estudo. Mediante as condições abordadas neste estudo, os capins Mavuno, Sabiá, Cayana e Llanero apresentaram maiores produções de massa seca total. Sendo apontada maior proporção de lâmina foliar para as forrageiras Sabiá, Cayana, Mulato II, Marandu e Xaraés. A proporção de colmo teve maior representatividade para o capim Quicuio, enquanto a altura nas forrageiras Xaraés e Mavuno. De modo geral, a densidade populacional de perfilho entre as cultivares Quicuio e Llanero foi similar, sendo as de resultado mais expressivo.
Application of Modern Methods for the Determination of Antibiotic Resistance

The increasing occurrence of antibiotic resistance is one of the major problems of the 21st century. The occurrence of bacterial strains resistant to antibiotics subsequently narrows the spectrum of suitable antibiotics usable for the treatment of common bacterial infections or for the prevention of their occurrence, e.g., in surgery. Wastewater treatment plants, hospitals, and also the food chain belong to the hotspots, where the emergence and spread of new or existing strains of antibiotic resistant bacteria and antibiotic resistance genes occur most frequently.

Phenotypic culture methods are routinely used in laboratories to determine antibiotic resistance, but they are laborious and time-consuming and the interpretation of exact results is also difficult. For this reason, faster alternatives for the detection of antibiotic resistant bacteria or even antibiotic resistance genes are sought. Such an example of an alternative method for the detection of antibiotic resistant bacteria is the use of the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry phenotypic method to identify the beta-lactamase producers. Genotype methods provide faster analysis and, at the same time, more accurate detection. Antibiotic resistance genes can be directly detected and quantified by polymerase chain reaction. Microarrays can be used to further speed up and increase the specificity of PCR amplicons detection.

Massive parallel methods provide comprehensive information on the resistoma of the specific environment. They facilitate sequencing of individual DNA molecules or amplicons to detect determinants of antibiotic resistance. Massive parallel methods have the potential to replace conventional pathogen characterization and allow the detection of all microorganisms in a sample (including difficult-to-cultivate or noncultivable microorganisms).

This review presents an overview of various advanced solid–liquid extraction techniques used for extraction of compounds with organoleptic properties from natural sources. These compounds are important additives to food, cosmetic, and pharmaceutical products. The most frequently used techniques are ultrasound assisted extraction and microwave assisted one, but there are other efficient techniques, such as pressurized liquid extraction, supercritical fluid extraction, pulsed electric field and enzyme assisted extraction. These techniques reduce or eliminate the volume of toxic solvents required for extraction, decrease the extraction time and mostly are more energy efficient. Low energy extraction conditions (pulsed electric field and enzyme assisted) can better preserve the compounds sensitive to heat, pH, and light.
