COMBATING INFODEMIC COVID-19: GOVERNMENT RESPONSE AGAINST FAKE NEWS ON SOCIAL MEDIA

The global commitment to fighting the pandemic is not only about medical and epidemiological work, but also about how information about the disease is disseminated. The threat of the Covid-19 infodemic is no less dangerous than the pandemic itself. The phenomenon of infodemic has distorted the work of science and reduced public trust in state authorities. This research has identified, mapped, and analyzed official government responses to fake news attacks on social media. This study uses an interpretive-phenomenological approach, related to the spread and belief of fake news about Covid-19 in Indonesia. Data analysis uses the Nvivo-12 Pro application, as an artificial intelligence tool to support data exploration from various sources. The results show that the quality of media literacy, public communication performance, and the effectiveness of government regulations have become part of the challenges in mitigating infodemic. The level of public trust in information from social media contributes to the decline in trust in fake news about Covid-19. Stimulation from the social media news that does not control the belief in myths and false information about Covid-19. Content creators who have produced, posted, and shared on social media channels that are less critical, have an impact on the infodemic situation. The solution is to increase media literacy education and the effectiveness of law enforcement in mitigating the infodemic in Indonesia

学びに活用するルーブリックの評価に関する方法論の検討

本稿では学びに活用するルーブリックの評価に関する方法論を検討する。ルーブリックを用いた評価が注目されるようになった背景を確認し、ルーブリックのタイプとその特徴を整理する。ルーブリックを用いた評価主体・方法に着目しながら、クラスルーブリック、コモンルーブリック、VALUE ルーブリックのそれぞれの活用実態を示す。また、先行研究の知見を踏まえ、ルーブリックによる評価にまつわる課題を指摘した上で、学びに活用するルーブリックの評価の質を保証するための方法論について検討する。特に、質的研究における妥当性に関する議論を手がかりに、ルーブリックを学びに活用するための知見を提示する。具体的には、ルーブリックの評価基準の妥当性の担保において、トライアンギュレーション概念が有効であるのに対し、ルーブリックの学びへの活用という点においては、妥当化、決定に至る足跡といった概念が有効であることを示す。最後に、評価活動への参加という観点から、学びとしての評価における学習メカニズムの仔細な検討が学びに活用するルーブリックの可能性を議論する上で重要な課題となることを指摘する

Performance of concretes produced with superplasticizer

Nowadays, additive chemical substances are used in the production of high-performance concrete composites. These additives increase the fresh workability of concrete by decreasing the water/cement (W/C) ratio. The aim of this study was to examine the effects of water-soluble polymers on concrete performance. For this purpose concretes with and without additives were produced with W/C values of 0.52, 0.56, and 0.60. Chemical admixtures such as naphthalene formaldehyde sulfonate (N), melamine formaldehyde sulfonate (S), and a hyperplasticizers admixture (a special type of melamine sulfonated polymer) (H) were used in concrete. The amounts of these admixtures were at a ratio of 0.3, 0.5, and 1.0 wt % of the cement's weight. Experiments assessing slump, VeBe, percentage of air, and unit weight were done for comparison with the test results of the characteristics of fresh concrete with and without admixtures. The compressive strength of concretes was determined at 7, 28, and 56 days. The effects of chemical admixtures were studied by comparing the properties of fresh and hardened concrete samples with and without admixtures. When the W/C ratios were 0.56, 0.60, and H was 1 wt %, the biggest slump was obtained and found to be 22 cm. Concrete with a W/C ratio of 0.52 and H of 1% has the highest compressive strength.

Purification of Fungal High Molecular Weight Genomic DNA from Environmental Samples

Sequencing of a high number of fungal genomes has become possible due to the development of next generation sequencing techniques (NGS).The most recent developments aim to sequence single-molecule long-reads in order to improve genome assemblies, but consequently needs higher quality (minimum >20 kbp) DNA as starting material.However, environmental-derived samples from soil, wood, or litter often contain phenolic compounds, pigments, and other molecules that can be inhibitors for reactions during sequencing library construction.In this chapter, we propose an optimized protocol allowing the preparation of high quality and long fragment DNA from different samples (mycelium, fruiting body, soil) compatible with the current sequencing requirements
