Comparative Analysis of Information Tendency and Application Features for Projection Mapping Technologies at Cultural Heritage Sites
Authors: LI Hengyi , ITO Hiromu
Published: June 2021

With the rapid development of interactive technologies using projection mapping (PJM), these digital technologies have introduced new interpretative possibilities for the presentation of cultural heritage sites. PJM attracts more visitors with greater expectations to cultural heritage sites through its excellent visual effects and guidance capabilities. In the past decade, especially after 2015, design events have frequently introduced digital projections to cultural heritage sightseeing spots worldwide. However, this trend has also led to the emergence of many digital projection events that merely exhibit beautiful projection effects on buildings and neglect to show the history and value of the cultural heritage site. Based on this phenomenon, this study compiled and analyzed 45 related cases of PJM applications at cultural heritage sites around the world from the past 5 years. These 45 examples were studied by disassembling the projection content, analyzing the information characteristics exhibited in each projection video, and arranging the obtained data on a timeline chart for analysis. According to the data, two information characteristics of PJM at cultural heritage sites can be observed: “the relationship between projection content and heritage” and “information tendency.” The advantages and limitations of these characteristics were distinguished and suggestions for the application of PJM on cultural heritage sites were derived. These results can be used as a reference for other research studies on visitors to cultural heritage sites and improving digital interpretation and presentation designs.

Wheat rusts, the dreadful fungal diseases caused by members of the Puccinia genus remain as a major threat to global wheat production and food security. The R-gene mediated resistance has been employed as an efficient approach to develop rust resistant varieties. However, evolution of new fungal races and infection strategies put forward the urgency of unravelling novel genomics assisted molecular players, including non-coding RNAs for rust disease management. MicroRNAs are crucial regulators of genes associated with plant growth, development, abiotic and biotic stress responses. In this study, high throughput small RNA sequencing was performed on susceptible and resistant wheat near-isogenic lines inoculated with stem rust and leaf rust, together with mock inoculated controls. While miRNA mining in stem rust inoculated libraries revealed a total of twenty-six known and seven novel miRNAs, the search in leaf rust libraries culminated with twenty-two known and four novel miRNAs. The identified candidate miRNAs constituted both guide and passenger miRNA strands along with their isomiRs. Temporal expression pattern of differentially expressed miRNAs pinpoints their possible role during the progress of infection. Comparative analysis provides a better understanding of altered miRNA profiles associated with Sr36 and Lr45 disease resistance genes in response to stem rust and leaf rust, respectively. Also, the disclosure of guide strand, passenger strand and a variant of novel-Tae-miR02 with various sub-genomal origins might serve as an important common link between stem rust and leaf rust defense mechanisms downstream to the respective R-genes. Further, cis-regulatory elements that modulate MIR genes, targets of identified miRNAs related to various signal transduction pathways, and miR-SSRs which might be useful for rust disease control, are the emphasized attributes of our results. The outcome from this simultaneous study of miRNA profiles among two rust diseases and further characterization of the identified miRNAs can contribute to the expanding rust disease management programs.

Production and scale efficiency of South African water utilities: the case of water boards
Authors: Ngobeni Victor , Breitenbach Marthinus C.
Published: June 2021

South Africa is a water scarce country with deteriorating water resources. Faced with tight fiscal and water resource constraints, water utilities would have to adopt technically efficient water management technologies to meet developmental socio-economic objectives of universal coverage, aligned to the United Nation's Sustainable Development Goal 6. It is important to measure the technical efficiency of utilities as accurately as possible in order to inform policy. We do this by using a non-parametric method known as Data Envelopment Analysis to determine, measure, analyse and benchmark the technical efficiency of all water boards in South Africa. Our contribution to the literature is twofold: This is the first paper to model technical efficiency of water boards as utility suppliers and guardians of water services in South Africa, and second, we address the over- and underestimation issues of technical efficiency measurement in the water sector. We do this by modelling one of the most pronounced negative externalities from water provision (water losses) as an undesirable output using the approach developed by You and Yan. We find, on average, technical efficiency of water boards is 49%, with only three of the nine water boards technically efficient. Six of the smaller water boards showed high levels of inefficiency with an inefficiency rate of 51%, which is equivalent to wastage in expenditure of R3.7 billion. Six water boards operate at increasing returns to scale and two are scale efficient. Only Rand and Sedibeng water boards exhibited decreasing returns to scale. Therefore, redirecting potential efficiency savings to optimal uses could result in technical and scale efficiency for the sector. Scale efficiency results seem to support larger regional water boards as small- to medium-sized water boards are scale inefficient with low technical efficiency. For example, Amatola Water (small water board) with an efficiency score of only 16% has a total expenditure of 18% of that of Umgeni (large water board), but sells only 6.7% of the quantity sold by Umgeni. Amatola also has seven times the proportion of water losses compared with Umgeni and charges 1.6 times the tariff of Umgeni. The ratio model with an undesirable output outperforms previous methods to deal with undesirable (bad) outputs, which either provide an over- or underestimation of technical efficiency.
Young people in the age of the COVID-19 pandemic: the age-related benefits and limitations
Authors: Yadova Maiya A.
Published: June 2021

This article explores the prospects of the impact of the COVID-19 pandemic on young people in Russia and abroad. Particular attention is paid to the phenomenon that modern researchers refer to as “coronavirus ageism”. This study shows that in the age of the pandemic, the young age becomes a natural resource that significantly increases the chances of adapting to the social transformations caused by the pandemic. The author’s sociological research of adaptation strategies and social practices of the post-Soviet youth in the age of the pandemic shows that digital acumen helps to overcome the negative consequences of the coronavirus crisis. The mediation role of the first digital generations in the modern world — Millennials and Generation Z — is important in transferring IT knowledge and skills to older generations. Thus, the intensity of intergenerational contacts can be considered as one of the key factors positively influencing the digital literacy of older generations. This fact provides an opportunity to look differently at the familiar problem of the generational gap. However, there are deprived young people for whom the prospects of succeeding in life in the age of the new coronavirus pandemic are slim. Many young people living in the world’s poorest countries (or regions) have limited access to digital technologies and education. Some young people are cut off from quality health services, which poses a threat not only to their health but also to their lives. Some young people are faced with the hardships of unemployment, suffer from violence, cannot cope with negative emotions and loneliness, have experienced the death of loved ones or friends, etc.
The municipal elections in the Krasnoyarsk Territory in 2005-2020 as reflected in a socio-political analysis
Authors: Zlotkovskij Vladimir I.
Published: June 2021

The relevance of the research topic is due to the important role that local self-government bodies play in people’s lives: according to experts, 70-80% of everyday life issues that concern most people on a daily basis are solved at the local level. Therefore, the search for an optimal model of organizing the local self-government and relationships between local and regional authorities are still urgent tasks for our country. The purpose of this article is to trace how the implemented models of the organization of local self-government, which provide for indirect elections of heads of local self-government, affect the formation of local authorities and whether it was possible to bring the municipal authorities closer to the population. This goal is realized by analyzing the results of four municipal elections in the Krasnoyarsk Territory held in 2005, 2010, 2015, and 2020. The 3rd model of the organization of local self-government is already applied for the specified time. The methods used include a sociological survey of the population and the analysis of electoral statistics and mass media. The results allowed making the following conclusions. First off all, a system of government has been created at the municipal level, characterized by stability, continuity, and manageability, in which the United Russia party plays a dominant role. At the same time, the results of the last election highlighted the shortcomings of this system. Secondly, the transition to indirect elections of heads of municipalities did not lead to the creation of an effective mechanism for selecting the most worthy local leaders. Third, the steadily declining electoral activity of citizens in municipal elections: 62.4% (2005); 39.6% (2010); 29.6% (2015); 24.6% (2020), and the number of supporters of the “party of power” reduce the legitimacy of local governments. Fourthly, citizens are beginning to place responsibility for the situation on the ground on regional authorities.
Recent Advances in Therapeutic Application of DNA Damage Response Inhibitors
against Cancer
Authors: Fernandes Stina George , Shah Prachi , Khattar Ekta
Published: June 2021

DNA’s integrity is continuously challenged by intrinsic cellular processes and environmental agents. To
overcome this genomic damage, cells have developed multiple signalling pathways collectively named as DNA Damage
Response (DDR) and composed of three components: (i) sensor proteins, which detect DNA damage, (ii) mediators
that relay the signal downstream and recruit the repair machinery and (iii) the repair proteins, which restore the
damaged DNA. A flawed DDR and failure to repair the damage lead to the accumulation of genetic lesions and increased
genomic instability, which is recognized as a hallmark of cancer. Cancer cells tend to harbor increased mutations
in DDR genes and often have fewer DDR pathways than normal cells. This makes cancer cells more dependent
on particular DDR pathways and thus become more susceptible to compounds inhibiting those pathways compared to
normal cells, which have all the DDR pathways intact. Understanding the roles of different DDR proteins in the DNA
damage response and repair pathways and the identification of their structures have paved the way for development of
their inhibitors as targeted cancer therapy. In this review, we describe the major participants of various DDR pathways,
their significance in carcinogenesis and focus on the inhibitors developed against several key DDR proteins.

In this work, we study the growth features, as well as the structural and optical properties of CaSi2 layers formed in the process of successive deposition of Si and CaF2 on a Si (111) substrate with simultaneous irradiation with high energy electron beam. The Raman spectra recorded in the regions of the electron beam action showed peaks characteristic of crystalline CaSi2 layers. The study of the surface morphology of the grown structures demonstrated that, under the chosen synthesis conditions, the formation of CaSi2 layers during electron irradiation occurs according to a two-dimensional layer mechanism. The photoluminescence spectra measured in the region modified by the electron beam have significant differences from the spectra measured outside this region.

Based on the numerical solution to the nonlinear Maxwell-Bloch equations, the joint implementation of active (parametric) and passive (coherent) mode locking for a class C heterolaser with a low-Q combined Fabry-Perot cavity in the presence of an effective distributed feedback of counter-propagating waves is demonstrated. It is shown that the multiplicity of the spectral width of the photonic band gap of the cavity to the intermode spacing far from this zone contributes to the effective phasing of quasi-monochromatic quasi-equidistant modes, thus making it possible a phenomenon of parametric coherent self-mode-locking. A number of examples are used to demonstrate typical properties of a quasi-periodic sequence of soliton-like pulses generated in the found regime, which does not require external modulation of the pump or laser parameters, or the placement of a fast-saturating absorber in it.

O socialismo utópico no pensamento político de Abreu e Lima
Authors: Rodrigues Theófilo Machado
Published: June 2021

A recepção do pensamento socialista de orientação marxista é bem conhecida na história política brasileira. Contudo, muito tempo antes dessa influência de Marx no Brasil uma certa literatura política nacional já desenvolvia temas relacionados ao socialismo no país. O presente artigo destaca o pensamento político do general Abreu e Lima, em particular aquele desenvolvido em seu livro O Socialismo. No livro, publicado em 1855, o general demonstra conhecer bem Babeuf e autores clássicos do socialismo utópico como Saint-Simon, Charles Fourier e Robert Owen. Deste modo, o presente artigo pretende demonstrar como o pensamento político de Abreu e Lima, em meados do século 19, influenciado pelo contexto histórico e social brasileiro, bem como pelo debate europeu, inseriu de forma pioneira o pensamento socialista no Brasil.

Published: June 2021

Contextualización: Una gran cantidad de productos químicos deben ser utilizados en la industria y sectores tecnológicos, generado el incremento de enfermedades laborales asociada a factores como el tiempo de exposición, la concentración.

Vacío de investigación: El desconocimiento de la peligrosidad sumado a las condiciones de operación de sustancias químicas cancerígenas que se presentan en el ejercicio de las actividades diarias en la industria pueden afectar la salud Humana.

Propósito: El objetivo del estudio es identificar y clasificar el riesgo relacionado con esas sustancias químicas en una planta procesadora de alimentos cárnicos en el departamento del Cauca (Colombia).

Metodología: En una primera fase de diagnóstico se realizó una búsqueda de información en bases de datos especializadas, en la segunda fase se desarrolla a partir de la información recolectada mediante el inventario de sustancias químicas en la planta, que se encuentran distribuidas en diferentes sitios de almacenamiento con probabilidad de exposición potencial. Para identificar la estimación del riesgo químico se aplicó un análisis cualitativo mediante la utilización del criterio de caracterización de riesgos “caja de herramientas de control químico internacional”. Posteriormente se hizo una revisión de normatividad que rige en Colombia relacionada a la manipulación, aplicativos y requisitos correspondientes de estas sustancias, estableciendo medidas de control y prevención necesarias a la naturaleza química de estos agentes.

Resultados obtenidos: Mediante el inventario se identificaron 407 sustancias presentes en la planta, de las cuales el 91% se clasifican dentro de sustancias químicas peligrosas y un 3 % corresponde a sustancias químicas con potencial efecto cancerígeno. Mediante la evaluación de riesgo se tuvo en cuenta la combinación de factores de peligro para la salud y exposición potencial que determinan el nivel de control deseado, dividida en cuatro niveles de abordaje (1, 2, 3, 4) siendo el abordaje 4 de consideración especial por ser el punto más crítico y de mayor peligrosidad.

Conclusiones: Finalmente se determinó que las sustancias de mayor atención en la planta son: el cemento portland, DQO solución B, Gasolina, Sikadur 32 Primer Comp B, Sikadur Panel Comp B, por estar dentro de abordaje 4.

intra-layer synchronization of the duplex networks. A duplex network
contains two layers ([1,2]). Different from the previous works,
environmental noise is introduced into the dynamical system of the
duplex network. We incorporate both the inter-layer delay and the
intra-layer delay into the dynamical system. Both of the delays are
time-varying. However, the paper [1] only considered the intra-layer
delays and they are assumed as the constants. While the paper [2]
did not consider the inter-layer delay or intra-layer delay. When the
system does not achieve automatic intra-layer synchronization, we
introduce two controllers: one is the state-feedback controller, the
other is the adaptive state-feedback controller. Interestingly, we find
that the intra-layer synchronization will achieve automatically if the
inter-layer coupling strength $c_1$ is large enough when the
time-varying inter-layer delays are absent. Finally, some interesting
simulation results are obtained for the Chua-Chua chaotic system with
application of our theoretic results, which show the feasibility
effectiveness of our control schemes.

Highlights

Healthcare organizations have prioritized patient safety and quality improvement efforts to reduce central line-associated bloodstream infections (CLABSIs). Implementation of central venous catheter (CVC) insertion and maintenance bundles have significantly reduced infection rates. Nevertheless, CLABSIs continue to be a significant cause of mortality and morbidity in hospitals, and further efforts are necessary to improve CVC care practices. A hospital-wide committee at a tertiary care pediatric hospital identified gaps in our CVC maintenance practices resulting from CVC contamination events from a patient’s body fluids. A lack of published literature on the topic resulted in the need to create an institutional clinical practice guideline (CPG) to develop guidance to mitigate potential CLASBIs from CVC contamination. Utilization of the CVC CPG in all inpatient units and other reduction strategies resulted in a steady decline in our CLABSI rates, particularly in those related to CVC contamination events. Case reports illustrate the effectiveness of the CPG.

Published: June 2021

Introdução: os potenciais evocados miogênicos vestibulares (VEMP) são respostas eletrofisiológicas que conseguem fornecer informações dos órgãos otolíticos sáculo, utrículo e do nervo vestibular. O VEMP é um exame complementar à avaliação vestibular, consistindo num exame rápido, de fácil aplicação e objetivo. Objetivo: analisar os parâmetros de latência, amplitude, limiar e índice de assimetria das respostas do VEMP cervical (cVEMP) e ocular (oVEMP) de indivíduos sem queixas vestibulares. Métodos: estudo transversal realizado com 53 indivíduos de ambos os sexos, sem queixas auditivas e vestibulares. Resultados: encontrou-se simetria de respostas nas latências, amplitudes e limiares de respostas do exame cVEMP. Entretanto, verificou-se diferença entre orelhas da latência P15 do exame oVEMP, sendo maior à direita no sexo feminino. Conclusão: Encontrou-se simetria nas respostas de todos os parâmetros avaliados do cVEMP. Houve assimetria apenas na latência de P15 do oVEMP no sexo feminino. Os limiares de resposta encontrados nos exames cVEMP e oVEMP foram iguais ou maiores que 75 dBNA.

Diante da perspectiva do desenvolvimento de narrativas em materiais didáticos digitais a partir de livros-jogo voltados para o contexto educacional, o objetivo é descrever como as narrativas desenvolvidas por estudantes do Ensino Superior ao construir livros-jogo utilizando o software Twine evidenciam a forma como pensam o ensino e a aprendizagem de conteúdos escolares. A pesquisa é qualitativa pautada em Estudo de Caso. São analisados 3 livros-jogo desenvolvidos por estudantes de Instituição Pública de Ensino Superior (IPES). A coleta de dados ocorre a partir de dois instrumentos: roteiro de elaboração e livro-jogo finalizado. A análise de dados ocorre por meio de triangulação metodológica pela comparação das informações obtidas nos dois instrumentos, acrescidos do referencial teórico, amparada pela Análise Textual Discursiva. Constata-se que em todas as estruturas narrativas, os conteúdos escolares não foram apresentados de forma expositiva; as narrativas não-lineares geraram atividades próximas de uma proposta construcionista de ensino.
COMPLEMENTARITY AS A FACTOR OF INTEGRATION IN AN EDUCATIONAL CLUSTER (ON THE EXAMPLE OF ECONOMIC EDUCATION)

Published: June 2021

В стратегии национального развития поставлена важная задача профессиональному образованию – подготовить кадры для обновления экономики и обеспечения ее конкурентоспособности на мировом рынке. Опыт профессионального образования свидетельствует о том, что образовательный процесс, последовательно осуществляемый в академической среде, а затем в сфере профессиональной деятельности, в условиях высокой динамики информационных процессов ведет к быстрому устареванию знаний. Определенная новым образовательным стандартом компетентностная направленность имеет усеченный характер, когда речь идет об инновационных продуктах, создание которых требует включенности субъекта в инновационный процесс. Актуализируется модель образовательного кластера, основанного на интеграции гетерогенных социальных сфер – образования и профессиональной деятельности, в целостности которых осуществляется подготовка специалистов. Исследуется основа интеграционной формы образовательного кластера – комплементарность субъектов гетерогенных социальных сфер, которые в статусе участников кластера могут привлекать дополнительные ресурсы в свою профессиональную деятельность. Выводы могут быть использованы при принятии решения региональных субъектов о вхождении в образовательный кластер для создания преимуществ собственного бизнеса.

The national development strategy sets an important task for vocational education – to prepare personnel for the renewal of the economy and ensuring its competitiveness in the world market. The experience of professional education shows that the educational process, consistently carried out in the academic environment, and then in the field of professional activity in the conditions of high dynamics of information processes, leads to a rapid obsolescence of knowledge. The competence orientation defined by the new educational standard has a truncated character when it comes to innovative products, the creation of which requires the involvement of the subject in the innovation process. The model of an educational cluster based on the integration of heterogeneous social spheres – education and professional activity, in the integrity of which the training of specialists is carried out, is updated. The article examines the basis of the integration form of an educational cluster – the complementarity of the subjects of heterogeneous social spheres, who, as members of the cluster, can attract additional resources to their professional activities. The conclusions can be used in making decisions of regional entities about joining the educational cluster to create the advantages of their own business.
