Authors: Leitmeyer Katrin Claire , Espinosa Laura , Broberg Eeva Kaarina , Struelens Marc Jean ,   the ECDC National Focal Points laboratory e-reporting survey group members
Published: October 2020

Background

Timely reporting of microbiology test results is essential for infection management. Automated, machine-to-machine (M2M) reporting of diagnostic and antimicrobial resistance (AMR) data from laboratory information management systems (LIMS) to public health agencies improves timeliness and completeness of communicable disease surveillance.

Aim

We surveyed microbiology data reporting practices for national surveillance of EU-notifiable diseases in European Union/European Economic Area (EU/EEA) countries in 2018.

Methods

European Centre for Disease Prevention and Control (ECDC) National Microbiology and Surveillance Focal Points completed a questionnaire on the modalities and scope of clinical microbiology laboratory data reporting.

Results

Complete data were provided for all 30 EU/EEA countries. Clinical laboratories used a LIMS in 28 countries. LIMS data on EU-notifiable diseases and AMR were M2M-reported to the national level in 14 and nine countries, respectively. In the 14 countries, associated demographic data reported allowed the de-duplication of patient reports. In 13 countries, M2M-reported data were used for cluster detection at the national level. M2M laboratory data reporting had been validated against conventional surveillance methods in six countries, and replaced those in five. Barriers to M2M reporting included lack of information technology support and financial incentives.

Conclusion

M2M-reported laboratory data were used for national public health surveillance and alert purposes in nearly half of the EU/EEA countries in 2018. Reported data on infectious diseases and AMR varied in extent and disease coverage across countries and laboratories. Improving automated laboratory-based surveillance will depend on financial and regulatory incentives, and harmonisation of health information and communication systems.

Published: October 2020

The article deals with the introduction of digital competences in the educational process of junior bachelors in agronomy. The model of development of digital skills of the population of the EU countries (EU Digital Competence Framework for Educators), the plan of the European model of digital competences for education is analyzed.

The traditional model of education is concerned with knowledge achieving and today it does not satisfy either the job market or students. Today, Ukrainian education is being transformed in line with world requirements, as evidenced by the introduced reforms in the system of education and the adoption of a new law on education. The paradigm of education is being transformed; models and learning approaches are changing. And, in general, research shows that the overall vector of change is aimed at developing digital competence, social and communication skills for successful activities in the digital world.

The examples of formation of digital competences in the process of training of modern specialists around the world and in Ukraine are given; taking into account the Framework of digital competence, the decision of the Ministry of Education and Science of Ukraine on reforming the education system is analyzed. According to the analysis of the labour market of the agricultural sector which there is a problem of non-compliance of the national structure of vocational education with the prospective needs of the agricultural labour market in terms of qualification level and structure of professional competencies of graduated agronomists, the main reason for which is non-taking into account the consideration in the process of preparation of the current state of use of information technologies in the areas of agricultural industry. Comparison of special (professional, subject) competences in accordance with the existing standard of training of junior bachelors in agronomy and the proposed list of competencies formed in accordance with current trends in global digitalization, including agricultural production is carried out. A thematic structure of the content of training for the formation of digital professional competencies for future agronomists is proposed. The issue of teaching a new discipline in terms of professional affiliation of the teacher is raised.

Authors: Golovchenko Glib
Published: October 2020

Today, in a digital society, media and information literacy, which is the result of media education, is considered vital. The importance of media education is acknowledged by Ukrainian authorities, researchers, practicing teachers, public organizations. Hence, Ukraine has acquired some experience in providing media education. The goal of the article is to analyze media education in Ukraine from the standpoint of regulatory and legal support and the experience of its practical implementation. A complex of scientific research methods was used to achieve the established goal: overview of literature and legislative documents; analysis, synthesis of the obtained results, prognostic method.

It was found out that a number of legal documents regulate the activities of the media sphere in Ukraine. However, the vast majority of them refer to the activities of the media or the regulation of the information sphere. Instead, the development of media information literacy is regulated not by a separate law, but in the context of a number of more global laws of Ukraine on education. Priority areas for further development of media education are defined in the Concept of media education for the period up to 2025. The analysis of the Concept regarding the forms of media education and the tasks facing them were analyzed. 7 forms of media education were characterized in the article: pre-school, school, out-of-school, higher school, for parents, for adults, non-formal media education. Inadequacy of using the term “media education through media” as non-formal media education was proved. The expediency of differentiating terms “non-formal” and “informal” media education was substantiated. Hence, one more form of media education was distinguished – "self-education through media". It is defined as a self-organized acquisition of digital, informational and media competencies during daily activities related to professional, social or other activities, family or leisure. The perspectives of further research were outlined, particularly as an empirical investigation.

Published: October 2020

This study examined the effect of macroeconomic determinants of stock price movements in Nigeria. To achieve this objective, data were gathered on macroeconomic variables such as gross domestic product, exchange rate, inflation, interest rate and absolute stock price were captured for the purpose of analysis. The autoregressive distributive lag (ARDL) model was used in analyzing the macroeconomic determinants of stock price movement in Nigeria. The augmented Dickey-Fuller (ADF) unit root test was also engaged in order to ascertain the stationarity or otherwise of the variables. The ADF unit root test revealed that only interest rate was stationary at levels while the remaining variables became stationary when differenced once. The ARDL findings revealed that the determinants variables (GDP, EXCHR, INTR, and INFL) were not jointly co-integrated with the dependent variable, ASTP, hence, no existence of a long run relationship. Conclusively, there was no long run relationship between macroeconomic determinants and stock price movements in Nigeria. It was recommended that, government should create conducive business environment, strengthen the real sector to stimulate the economy, boost savings and stock investment. Finally, government should fine tune its policies on exchange rate determination and setup a consistent policy plan to stimulate investment in the capital market.

Produksi limbah cair pengolahan kelapa sawit (POME) yang berlimpah di Indonesia menjadi faktorpendukung yang perlu menjadi perhatian, karena akan menimbulkan masalah lingkungan. Untuk itulimbah POME perlu dikonversi misalnya menjadi biogas, kemudian diupgrade menjadi biometana,agar beban pencemaran terhadap lingkungan akan berkurang. Konsep dasar upgrading biogasmenjadi biometana adalah untuk menaikkan kandungan metana (CH4) dalam raw biogas denganmenurunkan kandungan karbondioksida (CO2), untuk meningkatkan nilai kalori raw biogas. Selain itu,dilakukan pula penghapusan produk korosif, terutama hidrogen sulfida (H2S), air (H2O), dan beberapaunsur pengotor lainnya (H2, N2, O2). Proses ini dapat dilakukan dengan menerapkan berbagai jenisteknologi pembersihan dan peningkatan kualitas bogas. Teknologi tersebut diantaranya adalah aminescrubbing, water scrubbing, pressure swing adsorption, dan pemisahan membrane.Adapun distribusibiometana bisa dalam bentuk BioCNG, biasa disebut CBM (Compressed Biomethane), untukdigunakan sebagai bahan bakar pada sektor transportasi dan industri. Pola distribusi produk BioCNGyang paling layak adalah pemanfaatan BioCNG untuk kendaraan secara onsite. Model yangdigunakan berupa SPBG small fast fill, yaitu tipe SPBG dengan ukuran kecil, dimana pengisianBioCNG dilaksanakan secara cepat, seperti pengisian BBM di SPBU. Biaya pengadaan BioCNGtersebut adalah sebesar Rp. 4.242/LSP s.d. Rp. 4.563/LSP. Namun jenis distribusi denganmenggunakan tube trailers atau GTM (Gas Transport Module) ke SPBG Daughter sangat tidakekonomis, karena biaya pengadaan BioCNG-nya rata-rata lebih dari Rp. 8.000/LSP. Dengandemikian, untuk tipe distribusi jenis GTM - SPBG Daughter tidak dianjurkan untuk diterapkan diIndonesia.Kata kunci: BioCNG, Compressed Biomethane (CBM), SPBG, Gas Transport Module (GTM)

Pelagic fish, including sardines and anchovies (Order Clupeiformes), are the most common species taken by artisanal marine fisheries along the Togolese coast. We investigated fisher involvement as well as fish captures over a period of 10 years, particularly of the European anchovy (Engraulis encrasicolus). Our results indicate that 60% of fishers operated from the Lomé fishing harbour, most fishers being Ghanaians working seasonally in Togo. 63.7% of all the fishers used canoes with outboards, a higher percentage compared to the previous decades. Seven fishing gear type were identified, with bottom gillnet and surface gillnet being the most commonly used. However, in the most important fishing camp in the country in terms of fish production (Lomé fishing harbour), all fishers used shark nets. Overall, fisheries catches did not change significantly across years, but anchovy fishing effort and catch per unit of effort (CPUE) declined over the study period, suggesting some depletion of the species stocks on the Togolese coast and a demotivation of fishers.
