A mediação pedagógica em escolas da Paraíba: o papel docente na construção do conhecimento escolar
Authors: Dos Santos Pereira Aline , De Almeida Baptista Maria das Graças 
Published: February 2022

Resumo: Esse artigo é fruto da dissertação de mestrado e trata do processo de mediação na construção do conhecimento escolar fundamentado na psicologia histórico-cultural. O objetivo é compreender a concepção do (a) professor (a) dos anos iniciais acerca do processo de mediação em escolas municipais de João Pessoa-PB. Em um primeiro momento, é apresentado o pensar vigotskiano acerca da construção do conhecimento na escola como a elevação das funções psíquicas superiores dos indivíduos a partir da mediação do adulto em sua relação com a criança. Assim, é necessária para que o sujeito, a criança, se aproprie de sua própria historicidade. Apresentam-se, com brevidade, algumas perspectivas pedagógicas atribuídas ao vocábulo mediação na modernidade, destacando os fundamentos teórico-metodológicos em Vigotski, ou seja, o desenvolvimento das funções psicológicas superiores e a formação dos conceitos na idade escolar. Para o desenvolvimento dessa pesquisa, optou-se por uma abordagem qualitativa, uma vez que ela parte dos significados sociais e subjetivos a ele relacionados. À guisa de considerações finais, constatou-se diferentes concepções acerca do processo de mediação que apontam uma dicotomia entre teoria e prática, o que corrobora a reprodução da divisão do trabalho manual e intelectual no meio da força de produção.
Palavras-chave: Mediação pedagógica. Concepção do mundo. Construção do conhecimento.
Computation-in-memory simulation platform to investigate inference accuracy degradation by device non-ideality interactions in deep neural network applications
Authors: Higuchi Kazuhide , Matsui Chihiro , Misawa Naoko , Takeuchi Ken 
Published: February 2022

Abstract
This paper proposes a comprehensive computation-in-memory (CiM) simulation platform. The platform has the capability to emulate the degradation of inference accuracy caused by device non-ideality. In this paper, the effect of non-ideality by assuming non-volatile memory devices such as PRAM, ReRAM, MRAM, and FeFET in CiM were investigated. As the device is non-ideality, multi-level cell operation, conductance variation during verify-program, data retention error, sense amplifier offset, read current fluctuation, and device failure are considered. First, the acceptable amount of a single non-ideality was investigated. The results address that the conductance shift has much more of an adverse impact than conductance variation on inference accuracy in CiM. In the second place, interaction among multiple device non-idealities were also comprehensively investigated. The platform reveals paradoxical results that the inference accuracy of the combination of uniform shift and low conductance asymmetric error is higher than that of a single low conductance asymmetric error under specific conditions.

Kashiwagi, CMP Science, 26, (1977), the “most amazing technology that has contributed most to Moore’s law” according to Dr. Moore. Beginning with the CMP life cycle, this paper looks back on the history of CMP development, recognizes the current situation, and overlooks the future of polishing, cleaning, and monitoring. The paper also introduces the evolution of CMP, a revolutionary technology that emerged in the 1980s, together with some trivia from that period, and further introduces some episodes that are already or will be handed down as legends. In preparation for the paradigm revolution of semiconductors that is expected to occur in 2030, CMP software, as well as hardware, needs to advance more dramatically than before.
AlGaOx nanowires obtained by wet oxidation as a visible white phosphor under UV-LED illumination
Authors: Tanigawa Takeru , Tsutsumi Rikuo , Ishikawa Fumitaro 
Published: February 2022

Abstract
We obtain white luminescence by the oxidation of GaAs/Al-rich Al0.87Ga0.13As nanowire which is visible to the eye. The oxidized amorphous AlGaOx shell emits light over a wide spectral range covering entire visible wavelengths between 400–700 nm. The emission intensity depends on the oxidation temperature and time. Through the optimization of those conditions, we observe clear white light from the sample by the eye under the illumination of ultraviolet light-emitting diodes, which would be applicable as a white light phosphor.
Micro-print and nano-imprint methods combining laser-drilled screen printing and ultraviolet nanoimprint lithography: a review
Authors: Nakagawa Masaru 
Published: February 2022

AbstractUltraviolet (UV) nanoimprint lithography consists of molding–demolding and lithographic etching processes, which enable the shape transfer of molded resist patterns to underlying substrate surfaces. UV nanoimprint lithography has been applied in various fields, including optics, electronics, biology, and energy engineering. An important key to shape transfer through resist masks is to level the thicknesses of thin residual layers. To solve this issue, the region-selective placement of UV-curable droplets on a substrate is effective for leveling the thickness of the residual layer regardless of the differences in mold pattern density. Herein, we developed laser-drilled screen printing that allows the quantitative placement of high-viscosity UV-curable liquids on substrate surfaces via screen printing using a polyimide through-hole stencil mask prepared via ultrashort-pulse laser drilling. This review explains the practical demonstrations of UV nanoimprint lithography involving laser-drilled screen printing: nano/micro fabrication of Au split ring resonators, Au four-terminal electrodes, and silicon line patterns.
Measurement of liquid viscosity using series resonant resistance response of quartz crystal microbalance
Authors: Wang Yan , Li Chong , Zhao Baorui 
Published: February 2022

Abstract
Liquid viscosity measurement is widely used in petrochemical, medical and other fields, while the traditional viscosity measurement equipment is usually cumbersome and costly. This paper introduces a method for measuring the viscosity of liquid using the series resonant resistance response model of quartz crystal microbalance (QCM). In the confirmatory experiments of water and glycerol solution with 50% water content, the maximum absolute error is less than 4.50%, which shows the accuracy and validity of the theoretical model. At the same time, we found that the series resonant resistance response has higher accuracy and stability than the frequency response in the field test results of the viscosity of 0# diesel. This study is of great significance to the application of QCM in the liquid phase and has broad application prospects in the field of viscosity detection.

Abstract
We proposed a nitride semiconductor transverse quasi-phase-matched wavelength conversion device with a polarity inverted structure along the vertical direction formed by surface-activated bonding and etching processes. Inductively coupled plasma etching of a GaN layer with maintaining a root mean square roughness of less than 2 nm in a 100 μm square area was achieved even after deep etching of 1 μm using Cl2/Ar mixture gas and optimizing the antenna and bias powers. This smooth etching enabled surface-activated bonding of the ultrathin GaN layer with designed thickness. The fabrication process of the GaN polarity inverted channel waveguide was established.

Black rice contains high bioactive compounds that have antioxidant activity so that it has the potential as a source of functional food that can help to overcome various health problems. Black rice extract has high potential to be developed into an antioxidant beverage. Research on the content of bioactive compounds, antioxidant activity, and nutrients in black rice extract beverages has not been widely studied in Indonesia. The objective of this study was to determine the content of bioactive compounds, activity, and nutrients of black rice extract. Four types of commercial black rice grains were extracted using methanol as comparison (without treatment) and using water with a temperature of 90°C for 15 and 25 minutes, with the ratio of water: rice powder (20, 25 and 30 ml/ g). The black rice extracts were tested for total phenolic compound, antioxidant activity, protein, and iron content. The highest total phenolic content, flavonoids, and antioxidant activity of black rice extract beverages were 4.54 mg GAE/g (water ratio: rice powder 20 ml/g, 15 minutes), 14.51 mg QE/g (water ratio: rice powder 20 ml/g, 15 minutes), and 73.44% (water ratio: rice powder 30 ml/g, 15 minutes). The total protein and iron content of extract black rice beverage was 0.3115- 0.3620% and 0.0100- 0.0123%, respectively. The presence of high content of bioactive compounds, protein, iron, and antioxidant activity in black rice extract with a processing time of 15 and 25 minutes at 90°C, and the ratio of water: rice powder (20, 25, 30 ml/g) indicates that the processing conditions can provide a reference in producing black rice extract beverages which are rich in bioactive compounds, antioxidants, and nutrients. The presence of iron in brown rice extract may help overcome iron deficiency.
