A comparative study of the images of Mao Wenlong written by Chinese and Joseon literati: Centered on  and
Authors:   The Society For Chinese Humanities In Korea, . .
Published: September 2022

Mao Wenlong is a controversial figure in history. In the historical records, he is insolent, deceitful and inaction, but there is no denying that he was an important figure in Liaodong situation at the end of Ming Dynasty. Contrary to historical sources, Mao Wenlong in most literary works shows positive images. The phenomenon of divergence between literary processing and historical facts is, of course, inseparable from the intention of literary writers. For example, both the Ming Dynasty scholar Lu Renlong's  and the Korean Hong Ikhan's  have a lot of ink on Mao Wenlong's positive image. However, the two works are different in emphasis, because of their creative purposes, personal feelings, public opinion and different perspectives, the two authors have different portrayal of Mao Wenlong. On the basis of previous studies, this paper distinguishes the literary creation from the historical records, and analyzes the different aspects of the same character in the two works. Combining the internal and external perspectives, Mao Wenlong's literary image is re-examined through the creation of the same figure by Chinese and Korean literati.

Introduction. Prevention and control of African swine fever (ASF) transmission on the territory of the Russian Federation requires monitoring based on testing of samples from pigs and wild boars. Specific anti-ASFV antibodies are rarely detected in samples during routine serological diagnostics. Although, ASF isolates with weakened virulence were confirmed in Russia and neighboring countries.
The aim of this work was to determine the possibility of using alternative samples for ASF diagnosis and evaluate the effectiveness of the diagnostic methods used on the territory of Russia.
Materials and methods. Biological materials obtained from experimentally infected animals and samples collected in the field conditions were used in this study.
Results. Complex testing (RT-PCR and ELISA) is a more effective approach to diagnose chronic and asymptomatic forms of ASF compared to the separate use of these techniques. The possibility and efficiency of using alternative samples in diagnostics are demonstrated. It was confirmed that IPT method overcomes ELISA by high diagnostic sensitivity and detection of antibodies on earlier stages in extended range of samples. Anti-ASFV antibodies were detected in domestic and wild pigs in five regions of Russia. Samples from infected pigs that are negative in RT-PCR can be positive for anti-ASFV antibodies. The detection of antibodies in samples from shot wild boars (negative or uncertain in RT-PCR test) suggests the existence of animals surviving ASF infection.
Conclusion. The data obtained suggest a revision of the ASF surveillance strategy, by introducing complex diagnostic methods aimed at detection of both the virus genome and anti-ASFV antibodies simultaneously.

The human immunodeficiency virus (HIV) is currently one of the most pressing global health problems. Since its discovery in 1978, HIV has claimed the lives of more than 35 million people, and the number of people infected today reaches 37 million. In the absence of highly active antiretroviral therapy (HAART), HIV infection is characterized by a steady decrease in the number of CD4+ T-lymphocytes, but its manifestations can affect the central nervous, cardiovascular, digestive, endocrine and genitourinary systems. At the same time, complications induced by representatives of pathogenic and opportunistic microflora, which can lead to the development of bacterial, fungal and viral concomitant infections, are of particular danger. It should be borne in mind that an important problem is the emergence of viruses resistant to standard therapy, as well as the toxicity of the drugs themselves for the body. In the context of this review, of particular interest is the assessment of the prospects for the creation and clinical use of drugs based on small interfering RNAs aimed at suppressing the reproduction of HIV, taking into account the experience of similar studies conducted earlier. RNA interference is a cascade of regulatory reactions in eukaryotic cells, which results in the degradation of foreign messenger RNA. The development of drugs based on the mechanism of RNA interference will overcome the problem of viral resistance. Along with this, this technology makes it possible to quickly respond to outbreaks of new viral diseases.

Published: September 2022

This study moderates firm characteristics with key monetary variables (inflation rate and exchange rate) and examine their effect on the financial performance of fifteen (15) listed consumer goods manufacturing firms in Nigeria using an annual panel dataset from 2004 to 2020. The dependent variable (financial performance) is measured as return on assets while the independent variables are capital structure, dividend policy, managerial efficiency and firm size. In addition, the study used fixed and random effects regressions as techniques of data analysis. The results of this study are categorized into two parts namely; regression results without moderators and regression results with moderators (inflation and exchange rate). The result from the model without moderators shows that there is a positive and statistically relationship between capital structure, managerial efficiency and firm size and financial performance while dividend policy has no significant effect on financial performance. However, the results moderated with both the inflation and exchange rate indicate that capital structure and firm size have a significant negative effect on financial performance while dividend policy and managerial efficiency have a significant positive effect on financial performance. Thus, this study recommends the need for an increase in both dividend policy and managerial efficiency and limiting the increase in capital structure and firm size since they adversely affect financial performance. Finally, there is a need for consumer goods manufacturing firms to put into consideration the trends in monetary variables before making any investment decision.
Ludi Gladiatorial: as escolas de treinamentos e a formação de profissionais em torno dos espetáculos de combate
Authors: Rocha Ariza Maria
Published: September 2022

INTRODUÇÃO: Do ritual funerário aos espetáculos nos anfiteatros, os gladiadores desempenharam papéis sociais que se modificaram ao longo dos séculos século VIII a.C. ao século V d.C. da Antiga Roma. OBJETIVO: Com foco histórico-educacional, este texto tem o objetivo de analisar as escolas de treinamentos (Ludi gladiatorial) como modelo formativo nas formas de lutar, armamento, preparamento físico, estruturas de espetáculos, regras de lutas e convivência dos profissionais dos espetáculos de combate. MÉTODOS: Para tanto, recorri à pesquisa bibliográfica nas obras de Veyne (2009, 2015), Poehler (2013), Garraffoni (2004, 2005, 2006, 2007, 2008, 2010), Site do Parque Arqueológico de Pompeia, entre outras obras e fontes que favorecessem a compreensão da trajetória do gladiador e da sua formação para responder às necessidades daquela sociedade, mesmo que, considerados pertencentes à atividade infame, os gladiadores eram requisitados em rituais comemorativos religiosos, militares e entretenimento nos anfiteatros e em outros espaços sociais, institucionalizando os locais de treinamentos e da trupe (familiae gladitoriae) no contexto sociocultural e administrativa de romanos e não-romanos.RESULTADOS: As escolas de treinamento foram as instituições de preparação física, técnica e convivência entre diferentes sujeitos (lanistas, preparadores, lutadores e fãs) que institucionalizaram a profissão de lutadores nos espetáculos nas cidades locais e em trupe pelas cidades circunvizinhas e difundiam imagens de lutadores, atletas e gladiadores evidenciando a fama desses representantes da classe infâmia, contudo também revelam o modelo formativo aos jovens pela referência à coragem de “morrer lutando”, beirando o heroísmo, seja para fins militares e políticos, seja para fins disciplinares e punitivos. Tal mensagem incorpora-se aos espetáculos de massa, bem como à violência nas arenas.CONCLUSÃO: Naquela instituição, o modelo de formação do gladiador foi sedimentado pelos rituais funerários (munus), comemorações religiosas, conquistas de guerras e punição aqueles considerados “fora da lei romana”, sem esquecer de mencionar que tal modelo era exemplo de virilidade, força e fama atraindo jovens e voluntários da Roma Antiga e institucionalizando o combate de gladiadores em todo o domínio romano.

In certain circumstances, the hemostatic and inflammatory functions of platelets may overlap. Platelet–lymphocyte/leukocyte interactions can effectively regulate chronic inflammatory conditions. Platelet extracellular vesicles play a prominent role in thrombosis. In this review, we provide an overview of the molecules associated with platelet–cell interaction and the role of platelet extracellular vesicles in cardiovascular disorders and coronavirus disease 2019, which has posed a significant threat to global health due to infection with severe acute respiratory syndrome coronavirus 2. In addition to recruiting leukocytes to resolve inflammation associated with inflammatory diseases, such as coronavirus disease 2019, nutrients may also play a significant role in human metabolism.
Reinforcement-Learning Based Handover Optimization for Cellular UAVs Connectivity

The demand for services provided by Unmanned Aerial Vehicles (UAVs) is increasing pervasively across several sectors including potential public safety, economic, and delivery services. As the number of applications using UAVs grows rapidly, more and more powerful, quality of service, and power efficient computing units are necessary. Recently, cellular technology draws more attention to connectivity that can ensure reliable and flexible communications services for UAVs. In cellular technology, flying with a high speed and altitude is subject to several key challenges, such as frequent handovers (HOs), high interference levels, connectivity coverage holes, etc. Additional HOs may lead to “ping-pong” between the UAVs and the serving cells resulting in a decrease of the quality of service and energy consumption. In order to optimize the number of HOs, we develop in this paper a Q-learning-based algorithm. While existing works focus on adjusting the number of HOs in a static network topology, we take into account the impact of cells deployment for three different simulation scenarios (Rural, Semi-rural and Urban areas). We also consider the impact of the decision distance, where the drone has the choice to make a switching decision on the number of HOs. Our results show that a Q-learningbased algorithm allows to significantly reduce the average number of HOs compared to a baseline case where the drone always selects the cell with the highest received signal. Moreover, we also propose which hyper-parameters have the largest impact on the number of HOs in the three tested environments, i.e. Rural, Semi-rural, or Urban.
Hypothesis on a Parsi Community in Tamatave in the Second Half of the Nineteenth Century
Authors: Miele Matteo
Published: September 2022

Although there are already several significant works on the Parsi Zoroastrian diaspora in the panorama of historical research, many communities, stories, and aspects still remain unknown or little studied. In 1898, Delphine Menant mentioned two Parsis, partners of the London-based Parsi company Dadabhoy & C., in Madagascar. The information given by the French scholar, however, has not been followed up in more recent academic publications. This paper focuses on some British archival documents that would demonstrate a Parsi presence in Tamatave, since the 1870s. Through the study of some letters relating to the inheritance of a Parsi priest, the comparison with the later text of Menant and taking into consideration the larger Parsi community in Mauritius, it is possible to hypothesize a small community in the Malagasy coastal city. The article is also intended to be an invitation to other studies of the issue.
Material City

Urban development hinges on the availability of free space. The planned growth of Helsinki as reflected in the General plan of 2016 relies on identifying areas for infill in the urban fabric. In built-up areas there is a tendency to let the processes of urban change take place instead of top-down planning. This change is therefore not managed, but piecemeal, resulting in a patchwork of ‘stamp’ plans directed by narrow private economic considerations.       The life-span of buildings varies according to their material composition – also the type of a building and its spatial configuration affect its vitality. These attributes and conditions play a part in how long a building can endure before confronting the need for radical changes, and can be aggregated from open-source data and modeled using historical referents as benchmarks. This information forms a layer of probabilities in the city, revealing dormant locations facing imminent change.                 By mapping the information of the material conditions on the topography of the city, we can identify potentials for development. Identifying these latent sites in the city and engaging proprietors and landowners would give new tools for the City to affect the change and renewal associated with turnover of the building stock.
Which Is the Most Cost-efficient Alternative, a New Build or the Rehabilitation of a Cultural Heritage Site?
Authors: Stendebakken Mari Oline Giske , Olsson Nils O. E.
Published: September 2022

Given the choice between the rehabilitation of a cultural heritage site and a new build, recent history in Norway shows that the new build is often chosen, with the justification of cost efficiency.

This paper compares approaches to cultural heritage sites from a property development and a protection of cultural heritage point of view to test this judgment. These two professional fields overlap and need to cooperate. Thus, a closer look at their similarities and differences should provide valuable insights.

This paper applies a case-study method to a large country estate building at a NATO air base in need of office space. The building has legal protection at the national level. Costs are calculated for three scenarios for new offices: rehabilitation of the protected building, a new build, and renting. All alternatives include legally mandated maintenance of the protected building, as the same public body carries out both tasks.

Of the three alternatives, the new build and renting were the most expensive over a thirty-year time span. Rehabilitation was the most economical. These findings indicate that owners of protected buildings should investigate possibilities to activate such buildings, due to not only their cultural heritage values, but also their economic potential.

One of the challenges of Secondary Education is the use of new approaches and models for learning. The formal mathematical tools for the extraction of knowledge in Educational Databases and in particular the Implicative Statistical Analysis through the techniques of Similarity and Implication; they offer the teacher the possibility of diagnosing and promoting learning, transforming the educational reality through the discovery of quasi-involvement rules. Therefore, it is necessary for secondary school teachers to use the concepts and tools of Implicative Statistical Analysis, for this purpose learning environments based on simulation have been built for their learning. The research methodology used was quantitative, descriptive, cross-sectional, non-experimental; Surveys and data generated by simulations were used as research instruments. The following question was answered: How to use simulation environments for learning Implicative Statistical Analysis? It concludes by indicating how to apply the simulations for learning in general and the learning of the Implicative Statistical Analysis in particular.

El conocimiento y la información tienen el poder de transformar las economías y las sociedades. Las universidades, como instituciones de bien público se han convertido en el primer actor social para la generación de conocimientos organizados y en una plataforma para el desarrollo social. Está claro que en los países donde más inversión en educación hay, existe una mayor calidad de vida y hay un mayor ingreso per capital. En los países de América Latina la proporción de personas con educación terciaria es muy baja y, por ello, se ubican en la periferia de la sociedad del conocimiento, lo cual contrasta con el hecho de que, según el Banco Mundial, apenas el 20% de la población controla el 80% de la producción mundial. La mayor parte de los informes de importantes agencias, fundaciones y organizaciones internacionales coinciden en que en América Latina no se cuenta con el capital humano que se necesita para responder y competir contra las regiones que controlan la economía del conocimiento. Esto no se revertirá, en tanto, cada país no tenga la capacidad de incorporar el conocimiento a todos los sectores productivos y de servicio, sus instituciones de educación superior se mantengan al margen de las tendencias internacionales y no se integren a redes de universidades de clase mundial y no se logre el incremento de la tasa de graduados con estudios tecnológicos, de licenciatura, de especialización y doctorado. Ecuador, se ha caracterizado siempre por su riqueza cultural y ambiental. A partir del segundo lustro de este siglo, el país experimentó un crecimiento y una reducción de la pobreza importantes debido al boom del precio del petróleo. Ello permitió avanzar en materia de infraestructura para el desarrollo, en leyes y normativas destinadas a consolidar y desarrollar sectores prioritarios como la educación y la salud.
