This study was conducted to quantify the trend in dengue notifications in the country in 2017 and to explore the possible determinants. Annual nation-wide dengue notification data were obtained from the National Disease Surveillance of Ministry of Health of Indonesia. Annual incidence rate (IR) and case fatality rate (CFR) in 2017 and the previous years were quantified and compared. Correlations between annual larva free index (LFI), implementation coverage of integrated vector management (IVM), El Niño Southern Oscillation (Niño3.4), Dipole Mode Index (DMI), Zika virus seropositivity and the percent change in IR and CFR of dengue were examined. The change of dengue IR and CFRs were mapped. In 2017, dengue IR was declined by 71% (22.55 per 100,000 population) compared to 2016 (77.96 per 100,000 population) while the CFR was slightly reduced from 0.79% to 0.75%. Reduction in IR and CFR occurred in 94.1% and 70.1% out of 34 provinces, respectively. The trend of dengue IR seems to be influenced by Niño3.4 but there is no clear evidence that Niño3.4 is the main reason for dengue reduction in 2017. It is difficult to elucidate that the reduction of dengue in 2017 was associated with previous Zika outbreaks. In conclusion, there was a significant reduction on dengue notifications in Indonesia in 2017. Further investigation is needed to look at the role of climate on the decline of dengue IR at finer temporal scale. In addition, study on the role of cross-protective immunity generated by Zika infection on dengue incidence is also warranted.

In dengue-endemic countries such as Indonesia, Zika may be misdiagnosed as dengue, leading to underestimates of Zika disease and less foreknowledge of pregnancy-related complications such as microcephaly. Objective: To assess the attitudes of frontline physicians in a dengue-endemic country toward testing for Zika infection among patients with dengue-like illnesses. Methods: A cross-sectional online survey was conducted among general practitioners (GPs) in Indonesia. The survey assessed their attitude and also collected sociodemographic data, characteristics of their medical education, professional background, and workplace, and exposure to Zika cases. A two-step logistic regression analysis was used to assess possible variables associated with these attitudes. Results: A total of 370 GPs were included in the final analysis of which 70.8% had good attitude. Unadjusted analyses suggested that GPs who were 30 years old or older and those who had medical experience five years or longer had lower odds of having a positive attitude compared to those who aged younger than 30 years and those who had medical experience less than five years, OR: 0.58; 95%CI: 0.37, 0.91 and OR: 0.55; 95%CI: 0.35, 0.86, respectively. No explanatory variable was associated with attitude in the fully adjusted model. Conclusion: Our findings point to younger GPs with a shorter medical experience being more likely to consider testing for Zika infection among their patients presenting with dengue-like illnesses. Strategic initiatives may be needed to enhance older or longer-experienced physicians' capacity in diagnosing Zika infection.

Published: August 2021

The utilization of natural compounds as therapeutic agents to treat pancreatic cancer has recently focused on natural drug research. Calotropis gigantea has long been believed to be a medicinal plant that helps in treating various diseases. The bioactive compounds 9-metoxipinoresinol and isoliquiritigenin isolated from C. gigantea leaves are proven to act as therapeutic agents by inhibiting the cancer cell growth of Panc-1 cells. This study aimed to screen the potential molecular inhibition mechanisms of 9-metoxipinoresinol and isoliquiritigenin against pancreatic cancer development in-silico. We analyzed the activity of the aforementioned two compounds as inhibitors of several proteins that play a role in the growth of pancreatic cancer cells, such as GCNT3, GOT1, c-Met, PPARγ, BUB1, and NF-κβ, through molecular docking investigation. Our data suggested that 9-metoxipinoresinol and isoliquiritigenin were able to have well interaction with the target proteins, in which the predicted affinity energy ranged between -6.8 and 8.7 kcal/mol. The docking scores of 9-metoxipinoresinol and isoliquiritigenin were higher than the standard drug used (gemcitabine). Based on the binding affinity energy, GCNT3 and BUB1 are potentially to be used as target molecules for cancer therapy using 9-metoxipinoresinol and isoliquiritigenin, respectively.

The modern dimensions of corporate and managerial culture development in public administration in Ukraine has been justified. Corporate and managerial culture development is highlighted in particular different approaches. It is emphasized that the effectiveness of mechanisms in cultural modernization of public administration in Ukraine is a combination of objective (organizational-legal) and subjective (socio-psychological) components in development of corporate culture in public management. Objective components are analyzed, which provide for regulatory, structural, functional and methodological ordering the activities of state structures, taking into account the factors of corporate culture development. Subjective components have been shown to ensure the multidimensionality of communication tools. The basic characteristics of an innovative corporate culture such as knowledge, information, creativity and institutionalization are highlighted. It is proved that innovative corporate culture contributes to changing the status of professional activity of public servants, from managerial-controlling (power-influence), to consciously subordinate to the needs of citizens (power-interaction), and secondly to protect the culture of public administration from destructive influence global values and also the mobilization of public servants; and the public; consciousness towards engagement and mutual responsibility.

Authors: L. Hren , M. Chebotarev
Published: August 2021

Social work is aimed at meeting the vital and social needs of man. An important mission is assigned by the state to the head of a social institution who has a high level of professional competence. Competence is a key concept that characterizes the quality of professional training of the head of a social institution, his readiness for social activities and is one of the important factors in improving the quality of social services in the state. The essential features of the state personnel policy confirm the need for high professional competence in public administration. Competence is a concept that logically comes from attitudes to values and from skills to knowledge. The head of a social institution must have formed civic competencies, which is a prerequisite for national security. Participation in international projects (for example, in the Swiss-Ukrainian project "Development of Civic Competences in Ukraine – DOCCU") aims to use the best international experience in the formation of civic competences, promotes awareness of educators, civil servants, local governments on democratic citizenship and human rights. The structure of civic competence of the head of a social institution, which contains cognitive, value and activity components. Such projects contribute to the creation of conditions for the head of a social institution to acquire skills of civil law activity, self-organization and self-government. Conclusions and prospects for further research. So, based on the above, we came to the following conclusions: - the level of formation of civic competencies of the head of the social institution is an indicator of his readiness to perform his professional duties; - civic competencies of the head of a social institution, based on the national interests of the state, are an important prerequisite for national security; - We see the introduction of the obligatory discipline "Formation of civic competencies of the future head of a social institution" in the educational program "Social work" as a promising direction of further research.

Les principes fondamentaux de la motivation au travail : Vers une amélioration de la productivité des établissements de l’enseignement supérieur marocains
Authors: TARHI Mohammed Amine
Published: August 2021

Il est communément admis aujourd’hui, que les établissements de l’enseignement supérieur sont devenus aussi soucieux de leur productivité et de leur efficacité pareillement aux autres organisations. C’est ainsi, qu’on constate généralement un grand écart entre ces établissements dans leur efficacité et efficience ainsi que dans leur productivité et rendement. Cette distinction réside même à l’intérieur de ces établissements, où on se retrouve devant une divergence de productivité que ce soit de la part du corps professoral et ou du corps administratif.

Cette variation de productivité est intimement liée à l’autoritarisme, et pratiques de gestion adoptées par les managers, ainsi qu’à la motivation et à la valorisation accordée aux collaborateurs en place.

Studies on the monitoring of the most damaging defoliant species of oaks (Lymantria dispar and Totrix viridana) through pheromone traps in forest ecosystems are some of the rare achievements in this field, for our country. It has been shown that during the vegetation season there is an alternation of defoliant species, with the presence and development of the II generations, harmful to the foliar limb (the quantity of pests being higher during the first generations and reduced in the second generation). The activity of phytophagus insects was directly influenced by the climatic conditions in the studied areas, the presence of the nutrition source - oaks and the presence of the infestation source. Based on the evidence of males captured in the pheromone traps, digital maps of the spatial distribution of the imago of studied species were developed, which allowed the determination of the position, the direction of spreading and the size of the pests (the necessary studies in sustainable forest management).

The usefulness of the oak tree research is necessary both for scientific and practical reasons, knowing that the issue of ensuring the production of high quality forest seeds and the necessary quantity is an actual one. The researches show that the formation and development of the oak inflorescences, the amount of acorns reached maturity and the degree of its viability (in the region under study) were in direct correlation with the climatic parameters, during the vegetation period, the presence of defoliating and seminophage species , factors that can induce tree metabolic imbalances, low fructification, and premature fall of fruit. The most intense fructification was certified for the Ivancea research area, followed by the Codrii and Mereşeni areas.

There are over 300 high schools in the Republic of Moldova, most of which do not have 10-12th parallel classes, many of which also lead to the lack of qualified teachers in some subjects, which has a negative impact on the quality of students education. The optimization of the high school network can be achieved by keeping only about 100 of their existing number, planning them in new type institutions: district high-schools, boarding schools and mixed high schools of both these categories.
Highly Branched Cyclic Dextrin and its Ergogenic Effects in Athletes: A Brief Review
Authors: Wilburn Dylan , Machek Steven , Ismaeel Ahmed
Published: August 2021

Highly branched cyclic dextrin (HBCD) is a relatively new carbohydrate source that has gained much popularity in sports nutrition supplements, quickly becoming one of the most popular sports and fitness supplements globally. Due to its high molecular weight and low osmolality, HBCD is thought to provide an ergogenic advantage over other carbohydrate sources via faster gastric emptying and faster absorption. The purpose of this brief review is to explore performance claims and implications of HBCD use. We provide rationale for recommended use based on results of scientific studies conducted in both animals and humans.
Ciência e colonialismo em um periódico da Marinha francesa
Authors: Braga Daniel Dutra Coelho
Published: August 2021

Este artigo analisa formas por meio das quais a história natural foi abordada no periódico Annales maritimes et coloniales, editado pelo Ministério da Marinha e das Colônias, na França, a partir da Restauração Bourbon, até 1847. O artigo evidencia a comunicação entre o trabalho editorial da Marinha francesa e o campo da história natural francesa, assim como a própria inserção da Marinha nesse campo, mediante diretrizes de agricultura colonial, avaliações de viagens científicas e publicação de materiais oriundos de regiões portuárias francesas e territórios coloniais. Essas evidências permitem a crítica de estudos cujas interpretações enfatizam a oposição entre civis e oficiais no tocante à história natural e a oposição entre espaços metropolitanos e espaços coloniais.
primeiros artigos de William Crookes a respeito de fenômenos espiritualistas
Authors: Hidalgo Julianna M.
Published: August 2021

Em fins do século XIX, o cientista britânico William Crookes realizou pesquisas sobre fenômenos então chamados “espiritualistas”. Crookes propôs que alguns desses fenômenos estariam relacionados a uma nova força que chamou de “força psíquica”. Suas ideias não foram bem recebidas pela comunidade científica. O principal objetivo do presente trabalho é apresentar traduções de dois artigos de William Crookes relacionados a investigações sobre fenômenos espiritualistas. Ao longo das traduções apresentamos comentários a respeito da análise de questões envolvidas nas investigações, por exemplo, o controle de circunstâncias experimentais.

A pedido do rei português D. João V, o Vice-Rei do Brasil, Vasco Fernandes César de Meneses, erige uma academia de historiadores responsável por coletar informações sobre os domínios americanos da coroa portuguesa. A Academia Brasílica dos Esquecidos, organizada no ano de 1724 em Salvador, Bahia, contou com a presença de letrados que fizeram, naquele momento, a vez de intelectuais. Dentre eles, o chanceler do Tribunal da Relação da Bahia, Caetano de Brito e Figueiredo, foi o responsável pela elaboração de uma dissertação e respeito da natureza – geografia, céu, clima e zoologia – brasileira em que dispôs de novos elementos culturais fundamentados pela cultura das escolas jesuíticas espalhadas pelo território brasileiro. Com base no estudo da Dissertação de história natural do jurista lisboeta do tribunal brasileiro observaremos a singularidade e a novidade da cultura científica presente naquele lugar de saber da Bahia setecentista.

The COERSEA Model for Interactive Presentations
Authors: Koppi T. , Pearson E.
Published: August 2021

A commonly accepted theoretical paradigm in the
research and practice of effective learning and teaching is
constructivist. Researchers and practitioners in the higher
education community attend educational technology
focused conferences to share their findings, seek
feedback and collaboration, or challenge. Although
researchers may espouse constructivist methods in their
learning designs, this model is not adopted in their
presentations. Often a more traditional transmission
approach is used with the presenter inflicting many
content heavy slides on an increasingly passive audience.
The COERSEA model (context, outcomes, engagement,
resources, support, evaluation, alignment) comprises
seven principles that can be applied to the design of any
presentation be it a lecture, seminar or conference paper.
The model compliments current trends in online learning
design and represents a constructivist approach to
presentations that engages participants in a shared
learning experience. The model has been successfully
applied to a number of topics and contexts at
conferences, seminars and workshops.
Discoveries of Low-Sulfidation Epithermal Au-Ag Veins at Cerro Negro, Deseado Massif, Argentina
Authors: SHATWELL D. , CLIFFORD J. A. , ECHAVARRÍA D. , IRUSTA G. , LOPEZ D.
Published: August 2021

Exploration by Andean Resources Ltd. in the Cerro Negro district of southern Argentina between March 2005 and July 2010 delineated resources of 2.54 Moz gold and 23.5 Moz silver in three low-sulfidation epithermal vein deposits. Two of these, Eureka West and Bajo Negro, are new discoveries; the third deposit, Vein Zone, had been explored previously. Additional measured and indicated resources of 2.7 Moz Au have been estimated by current owners Goldcorp Inc. for three other discoveries at Cerro Negro: San Marcos, Mariana Norte, and Mariana Central. The total gold resource for the project is 5.3 Moz Au measured and indicated, plus 1.24 Moz inferred.

Andean completed a positive feasibility study into an underground and open pit mining operation in July 2010, based on reserves of 2.07 Moz Au and 20.6 Moz Ag at Eureka, Bajo Negro, and Vein Zone. The study concluded that these deposits can produce an average of 200,000 oz of gold and 1.8 Moz of silver per year for 10 years, which would make Cerro Negro the largest gold producer in the Deseado Massif without considering resources or production from the other three deposits.

The deposits are hosted by Late Jurassic volcanic and probable intrusive rocks of the Deseado Massif in which Triassic-Cretaceous extension created the structures which control the precious metal vein deposits. Four of the five new discoveries were found through geologic mapping, but pioneering work by previous explorers also contributed; the two most recent discoveries do not crop out. Geophysical studies helped to define drill targets and are likely to be increasingly important in future exploration.

A key ingredient in Andean’s success was a willingness to drill test targets identified by a skilled and dedicated, largely Argentine, exploration team, supported by Australian and North American-based management.
Discovery, Innovation, and Learning in the Mining Business – New Ways Forward for an Old Industry
Authors: Enders M. Stephen , Saunders Cliff
Published: August 2021

There is a huge opportunity to develop new business models for the mining industry. Exploration and discovery must be based on a model of cooperation and collaboration rather than competition. Innovation and the development of new technology must be based on what we need to do to transform the business for tomorrow, in addition to what we can do today. Accelerated learning based on business simulations offers an excellent new approach to discovering what needs to be changed, to developing new and creative approaches to actually change our cultures of practice, and to implementing those changes as rapidly as possible. Simply put: we have to change our mindset to change our mine set.
The Kalahari Copperbelt in Central Namibia: Controls on Copper Mineralization
Authors: Maiden Kenneth J. , Borg Gregor
Published: August 2021

The Kalahari Copperbelt stretches discontinuously for 800 km from central Namibia to northern Botswana (Figure 1; Borg, 1988; Borg and Maiden, 1989). In central Namibia, copper mineralization, hosted by slate and phyllite, is intermittently developed over more than 60 km of strike of the Kagas Member of the Klein Aub Formation. The strata-bound nature of copper occurrences led early explorers to the conclusion that copper was either syngenetic, i.e., emplaced during deposition of the host strata, or diagenetic, i.e., emplaced into the host strata during burial and compaction. As a result, initial exploration largely focused on “favorable” stratigraphic units as target horizons and for the most part ignored structurally controlled target areas of significant economic potential.

Subsequent research at the (presently inactive) Klein Aub Mine and elsewhere in the Namibian part of the belt showed that, although copper concentrations are broadly strata-bound, the structural associations (e.g., the relation to a late reverse fault at Klein Aub) and detailed textural features (e.g., copper in veins, brittle fractures, cleavage-parallel lenticles, and tectonic breccia zones) indicate that copper mineralization was emplaced into structurally controlled sites late in the deformation history of the region.

The conclusion of the present review is that economically viable copper accumulations resulted predominantly from one or more regionally extensive but locally structurally controlled hydrothermal events, mostly subsequent to formation of the dominant cleavage. As a result, modern exploration should focus primarily on favorable structures, particularly potential dilatant sites in tectonically complex zones.
