Published: December 2020

BACKGROUND: Aircraft seat manufacturers are making efforts to reduce seat weight while continuously increasing seating comfort. OBJECTIVES: To verify if seats with an optimally pre-shaped foam support could improve seating comfort while reducing seat weight. METHODS: The optimally pre-shaped surface was obtained from a synthesis of 95% of individually optimized compressed seat pan surfaces of a target population. Two new seats were proposed with two different cushions, one slightly softer and the other harder. Nineteen differently sized volunteers tested the two new seats and an existing seat randomly. After an assessment of initial discomfort, participants were instructed to watch a TV series for 50 minutes. A same questionnaire was used to assess both initial and longer-term discomfort. Contact forces and pressure distribution were analysed as well in-chair movements (ICM) during sitting. RESULTS: The two new seats exhibited lower shear, lower peak pressure and larger contact area on the seat pan as well lower number of ICM during the 50 minutes sitting. They also had lower initial overall discomfort, though significant differences between the seats were not found after the long sitting. CONCLUSIONS: Properly pre-shaped surface could be used as foam support to reduce the amount of foam while reducing seating discomfort.

BACKGROUND: Many occupations require workers to stand for prolonged periods, which can cause discomfort, pain and even injures. Some supermarkets in life provide a foot pad for checkout staff to let them stand on it at work, thereby reducing standing fatigue caused by standing for a long time. The inclined platform is the same as the foot pad mentioned above. That is, the staff stepped on it and relieved standing fatigue to a certain extent. OBJECTIVE: The study aims to analyze how the standing angle affects fatigue among prolonged standing workers and tries to find an inclined platform with a specific angle to reduce standing fatigue. METHODS: This experiment studied fatigue of the inclined platforms with different angles on prolonged standing workers, eight participants were selected to participate in the test. The plantar pressures and sEMG (Surface Electromyography) were used to collect the physiological information change of prolonged standing participants in the lower limb and waist. The visual analogue scale was used as a subjective method to measure the psychological fatigue. RESULTS AND CONCLUSION: The study highlights the relationship between standing angle and lower limb fatigue. The inclination of the standing platform has different effects on the participants under different time conditions. When participants stand on inclined platforms at 0°, 5° and 10°, the iEMG (Integrated Electromyography) values of the gastrointestinal muscle were not significantly different until the third sampling point (40 minutes). After that self-regulation of lower limb muscles is better when standing on an inclined platform between 5° and 10°, it has a certain effect on alleviating lower limb fatigue. This knowledge is crucial for the design of the inclined working platforms fitting the needs of prolonged standing workers.

The article tells the story of Henryk Ryszewski, who provided hiding to about a dozen Jews in his flat in the Warsaw district of Mariensztat. Accused after the war of blackmailing Jews (as I think, wrongly), he was convicted and spent several years in prison. His prosecutor fell victim of the ‘paper industry affair’ show trial and also spent a few years in prison.

O presente estudo almeja desvelar as concepções dos docentes sobre o uso das tecnológicos da informação e comunicação no contexto educacional, especificamente na Educação Básica do município de Jaguaruana-Ceará, bem como suas reflexões acerca dos desdobramentos da inserção desses recursos no período da pandemia do COVID-19, a partir do ensino remoto. Fundamentando-se em procedimentos metodológicos que misturam métodos quali-quantitativos, tendo como referência a pesquisa bibliográfica, a partir de Santos (2009), Moran (2000), e da pesquisa de campo, pois utilizamo-nos de questionários eletrônicos aplicados a professores. Nossos achados permitiram refletir que o processo adaptativo dos professores ao ensino remoto ora denota a falta de familiaridade com as TDIC, ora demonstra a tentativa de aprendizado com os recursos. Sobre a prática pedagógica nas escolas do município, os desafios denotam: as limitações da formação docente inicial e continuada; a precarização da profissão; a falta de infraestrutura física e recursos tecnológicos nas instituições; a inacessibilidade aos meios tecnológicos pelos discentes e docentes, seja na escola no domicílio e a ausência de políticas públicas para inclusão digital dos sujeitos escolares. Todos estes desafios marcados pela desresponsabilização do Estado na democratização do acesso e permanência na escola/sucateamento da educação. Diante disso, acreditamos que antes de se pensar em ensino remoto, em ensino híbrido deve-se haver a democratização da educação e das TDIC, pois a educação é um direito constitucional.

Dual microwave-excited atmospheric-pressure plasma jets with a single power source
Authors: Lim Daecheon , Uddin Md Nazim , Choi Sangjo , Choi Dongyeon , Choi Jun 
Published: December 2020

Abstract
In this paper, we propose dual microwave-excited atmospheric-pressure plasma jets (DME-APPJs) that can be generated with a single power source. A T-junction power divider that evenly distributes the input power to two ports is used, and two coaxial transmission line resonators are used as plasma generators for the DME-APPJs. The power divider distributes the incoming power in port 1 and supplies 46% of this power to port 2 and port 3, respectively. Surface treatments are conducted by exposing the multiple plasma jets to polypropylene (PP) specimens and then confirming the degree of hydrophilic change. Using the proposed DME-APPJs, it is possible to perform surface treatments on areas that are up to 50% larger compared to using two single ME-APPJs with the same power consumption. The DME-APPJs thus show more advanced performance for surface treatments by comparison with the single ME-APPJ.

Avoidable Paths in Graphs
Authors: Bonamy Marthe , Defrain Oscar , Hatzel Meike , Thiebaut Jocelyn 
Published: December 2020

We prove a recent conjecture of Beisegel et al. that for every positive integer $k$, every graph containing an induced $P_k$ also contains an avoidable $P_k$. Avoidability generalises the notion of simpliciality best known in the context of chordal graphs. The conjecture was only established for $k \in \{1,2\}$ (Ohtsuki et al. 1976, and Beisegel et al. 2019, respectively). Our result also implies a result of Chvátal et al. 2002, which assumed cycle restrictions. We provide a constructive and elementary proof, relying on a single trick regarding the induction hypothesis. In the line of previous works, we discuss conditions for multiple avoidable paths to exist.
SOME QUESTIONS OF PROCEDURAL POWERS IMPLEMENTATION BY EMPLOYEES OF THE FEDERAL PENITENTIARY SERVICE OF RUSSIA WHEN MAKING PROCEDURAL DECISIONS AT THE STAGE OF INITIATION OF CRIMINAL PROCEEDINGS

Published: December 2020

В статье рассматриваются актуальные проблемы реализации уголовно-процессуальных полномочий органов и учреждений УИС в стадии возбуждения уголовного дела. В частности, рассмотрена проблема и дано определение компетенции органов дознания и предварительного следствия, предусмотренной УПК РФ. Исследован объем уголовно-процессуальных прав и обязанностей органов дознания и следствия, а также оперативных подразделений УИС в системе иных органов дознания и следствия. Проведен анализ порядка принятия решений уполномоченными должностными лицами ФСИН России при проверке сообщений о преступлениях, выражено мнение о том, что они вправе принимать только одно решение: о передаче сообщения о преступлении по подследственности и в исключительных случаях возбуждать уголовные дела в порядке, предусмотренном ст. 157 УПК РФ. Рассмотрены причины, на основании которых законодатель уменьшил полномочия оперативных подразделений ФСИН России как органа дознания. Рассмотрены актуальность применения ст. 157 УПК РФ в части возбуждения уголовных дел и проведения по ним неотложных следственных действий, а также роль начальников органов и учреждений УИС в их проведении. На основании рассмотренных проблем подведен итог о нечеткой регламентации процессуальных полномочий органов и учреждений ФСИН России в уголовно-процессуальном законе и подзаконных актах на стадии возбуждения уголовного дела.
The article deals with the actual problems of implementation of the criminal procedure powers of the criminal procedure authorities and institutions at the stage of criminal proceedings. In particular, we consider the problem and the definition of the competence of bodies of inquiry and preliminary investigation under code of criminal procedure. The volume of criminal procedure rights and obligations of operational divisions of the criminal investigation department in the system of other bodies of inquiry and investigation is studied. The analysis of the procedure for decision-making by authorized officials of the Federal Penitentiary Service of Russia when checking reports of crimes is carried out. The reasons why the legislator reduced the powers of operational divisions of the Federal penitentiary service of Russia as a body of inquiry are considered. The relevance of the application of article 157 of the criminal procedure code of the Russian Federation in terms of criminal cases and conducting urgent investigative actions on them, as well as the role of the heads of criminal investigation bodies and institutions in their conduct, were reviewed. Based on the problems discussed, the author summarizes the lack of regulation of the procedural powers of the Federal Penitentiary Service bodies and institutions in the criminal procedure law and by-laws at the stage of initiation of a criminal case.
