Bem-estar, desenvolvimento e atividades organizadas: um estudo com alunos adolescentes
Authors: Carvalho Nuno Archer de , Veiga Feliciano Henriques
Published: July 2021

Enquadramento: No estudo do Bem-estar psicológico e dos Recursos de desenvolvimento, destaca-se a participação dos adolescentes em atividades organizadas. Objetivo: Aprofundar a relação do Bem-estar psicológico e dos Recursos de desenvolvimento com a participação em atividades extracurriculares e de solidariedade. Metodologia: O estudo incluiu 201 alunos do 6º, 9º e 11º ano de uma escola particular portuguesa e usou a Escala de Bem-Estar Psicológico para Adolescentes, o Developmental Assets Profile e três questões sobre a participação nas atividades. Resultados: Encontrou-se um número elevado de alunos que participam em atividades dos dois tipos. A participação diminui ao longo da adolescência. As correlações com o Bem-estar psicológico e os Recursos de desenvolvimento reforçam o potencial da participação nos dois tipos de atividade para o bem-estar e o desenvolvimento dos adolescentes. As diferentes correlações sugerem uma maior ligação da participação em atividades extracurriculares com a auto-estima, e entre a participação em atividades de solidariedade com a autorrealização, o crescimento pessoal e a resiliência. Conclusões: Valorização das oportunidades de participação em atividades dos dois tipos nos contextos educativos, com destaque para a escola. São apresentadas sugestões para estudos futuros.
Diretrizes curriculares nacionais para a formação inicial de professores: padronizar para controlar?
Authors: Simionato Margareth Fadanelli , Hobold Márcia de Souza
Published: July 2021

Este artigo visa discutir a padronização da formação inicial dos professores, imposta pelo Parecer CNE/CP no 22/2019 e Resolução CNE/CP no 02/2019, como uma “grade” formativa que retira o sujeito e a subjetividade docente do centro do processo formativo, concentrando atenções na dimensão técnica da formação com competências e habilidades predefinidas e estabelecendo estandartes que poderão ser utilizados numa avaliação docente de larga escala em forma de auditoria. Essa normativa fabrica identidades docentes quando prescreve os modos de ser professor/a e do fazer pedagógico e alinha a formação ao conteúdo da BNCC, dentro do modelo gerencial que subjaz ao pacote reformista em curso. Há reordenamento e profunda mudança nos fundamentos, objetivos, conteúdos e estrutura da formação inicial, fortemente associada à cultura de performatividade, voltada à gestão de resultados em consonância com o projeto do capital. São mudanças que expropriam o professor de seu modo de produção, propondo o controle do trabalho docente que busca submeter os saberes tácitos construídos em situações de trabalho e subsidiam sua prática, sua artesania docente. Esse engessamento traz em seu bojo a intencionalidade de expropriação do saber criativo, constituído pelos conteúdos vinculados ao campo da arte, estética, análise crítica de contexto, fortalecimento dos aspectos éticos, etc., inerentes à formação cultural e ao desenvolvimento humano. Considerando essa intencionalidade formativa, delineia-se uma cultura de heterogestão, constituída pela padronização, controle e avaliação (pautas da Nova Gestão Pública –NGE); campo fértil para a implantação da ideologia baseada no livre mercado competitivo que perpetua e intensifica a exploração do trabalhador.
Inserção da terminologia “direito à aprendizagem” no arcabouço legal da formação de professores

Tem-se como pressuposto que as Diretrizes Curriculares Nacionais para a Formação Inicial de Professores para a Educação Básica e o anexo denominado Base Nacional Comum para a Formação Inicial de Professores da Educação Básica (BNC-Formação) aportam-se em abordagem de viés economicista em consonância com o projeto ultraliberal em curso. Argumenta-se que o Parecer CNE/CP no 22/2019 e respectiva Resolução CNE/CP n. 02/2019 e Parecer CNE/CP no 14/2020 e Resolução CNE/CP no 1/2020 recuperam um projeto de formação de professores ancorado na racionalidade técnica vencido política e institucionalmente no início dos anos 2000. Almeja-se desvelar em quais princípios se apoia e quais elementos caracterizam o projeto de formação docente inscrito nas ‘novas’ diretrizes. Recorre a pesquisa documental, detendo-se particularmente na análise da inserção da terminologia “direito à aprendizagem” nas novas diretrizes com vistas a desnudar as implicações para a formação inicial de professores. Almeja-se, portanto, traçar o percurso que propiciou a incorporação do termo “direito de aprendizagem” nos normativos atinentes a formação de professores. Adota o conceito de aprenderismo e tem Biesta (2012, 2013, 2017) como autor de referência para analisar o discurso legal. A substituição no texto normativo da linguagem da educação pela linguagem da aprendizagem é materializada na BNC-FI e na BNC-FC com a listagem das competências e habilidades, obliterando o lugar do conhecimento no projeto de formação de professores e, por conseguinte, na formação de estudantes na educação básica, indicando a influência de uma matriz calcada na racionalidade técnica nos processos formativos em detrimento de uma fundamentação assentada na racionalidade crítica.

Pembrolizumab induced hyperpigmentation in a patient with lung adenocarcinoma: a case report
Authors: Zhou Yulu , Huang Guolin , Wei Yanzheng , Yu Zaoqin , Wu Jiayao
Published: July 2021

Pembrolizumab is more widespread use clinically with Pembrolizumab being
recommended as a first-line therapy for advanced NSCLC. At the same
time, some new adverse reactions have also been discovered, including
hyperpigmentation. We hereby present a 77-year-old Chinese female with
primary bronchial lung cancer. Genetic testing showed negative for EGFR
and ALK. Immunohistochemical analysis showed tumor proportion score
(TPS) of PD-L1 was 80% on tumor cells. Then the patient received
pembrolizumab 200mg every three weeks, as the first-line therapy. Two
courses after initiation pembrolizumab, hyperpigmentation appeared on
her face and back of the hand. The right middle lobe mass and
mediastinal lymph node metastasis progressed after nine courses after
initiation of pembrolizumab, and the patient’s entire face turned black.
It potentially indicates that cutaneous adverse events of
hyperpigmentation, might be a negative predictor of response to
pembrolizumab in metastatic lung adenocarcinoma patients.
Analysis of patient-specific NF1 variants leads to functional insights for Ras signaling that can impact personalized medicine
Authors: Long Ashlee , Liu Hui , Liu Jian , Daniel Michael , Bedwell David , Korf Bruce , Kesterson Robert , Wallis Deeann
Published: July 2021

We have created a panel of twenty-nine NF1 variant cDNAs representing
benign missense (MS) variants, pathogenic MS variants, many with
clinically relevant phenotypes, in-frame deletions, splice variants, and
nonsense (NS) variants. We have determined the functional consequences
of the variants, assessing their ability to produce mature neurofibromin
and restore Ras signaling activity in NF1 null (-/-) cells. cDNAs
demonstrate variant-specific differences in neurofibromin protein
levels, suggesting that some variants lead to protein instability or
enhanced degradation. When expressed at high levels, some variant
proteins are still able to repress Ras activity, indicating that the NF1
phenotype may be due to protein instability. In contrast, other variant
proteins are incapable of repressing Ras activity, indicating that some
do not functionally engage Ras and stimulate GTP-ase activity. We
observed that stability and Ras activity can be mutually exclusive.
These assays allow us to categorize variants by functional effects, may
help to classify variants of unknown significance, and may have future
implications for more directed therapeutics.
Eros and Agape – a Critique of Anders Nygren
Authors: Tollefsen Torstein Theodor
Published: July 2021

Nygren’s book Eros och Agape was first published in Sweden in 1930/36. It was then published in English translation in 1953 under the title Agape and Eros. The author’s idea was to describe the development of the Christian concept of love through the centuries. Nygren argued that eros is the term for Platonic, self-centred love that strives for union with the divine realities, while agape, denoting the Christian concept of love, is the free, divine movement towards human beings. Agape is unselfish and is not motivated by any value in the recipient. This distinction drawn by Nygren has been so influential that it has been taken for granted in a lot of Christian contexts worldwide, even if one does not associate it with the name Nygren. In this paper his methodology and the distinction he draws are criticised. He finds in eros and agape two so-called “fundamental motifs” that, as he sees it, unfortunately merge in Christian tradition and thereby obscure the original Christian understanding of love that emerges in its purest form in St Paul and later in Luther. There are a lot of problems in Nygren’s book. He argues, for instance, that Christianity emerges from Judaism as a completely new religion, and separates the Old and the New Testament as if they had nothing in common. Agape as the divine gift to human beings excludes all human activity since God has freely and graciously chosen human persons as his slaves. In the present paper it is argued that Nygren’s methodology is unsound and that his conclusions are not even in agreement with the New Testament.
A Neo-Platonic Dialogue on the Ethics of Love*
Authors: Vasilakis Dimitrios A.
Published: July 2021

In his classic paper on “The Individual as an Object of Love in Plato” Gregory Vlastos denied that according to Plato’s Diotima in the Symposium a human individual can ever be the proper object of one’s erotic desire, because what one (should) be enamoured with is the Form of Beauty. For the true Platonic lover, the beauty of an individual is only the starting-point for one to understand that beauty can reside also in more abstract levels. Hence, Vlastos argues that the beloved individual is for his lover only a means to an end, so that the lover recollects and attains to true Beauty, and that this is morally objectionable. The systematic Neoplatonic philosopher Proclus (412–485 AD) had already given an answer to this accusation. I will first present the altruistic side of Eros as an ontological entity in Proclus’s metaphysical system. My guide in this will be Socrates, as well as the Platonic Demiurge from the Timaeus and Republic’s philosopher-king. It will be shown that, according to Proclus’s interpretation of various Platonic texts, Vlastos was wrong to accuse Plato of the abovementioned “instrumentality” on the erotic field. However, my paper will close with a critical engagement with Proclus too, since I discern that in his view of Platonic love another sort of instrumentality, one which is akin to Stoic ethics, arises. Vlastos was wrong, but we do not need to be wholeheartedly sympathetic to Proclus.

Coronavirus Disease 2019 (Covid-19) Pandemic had been hitting throughout the world since early 2020. Indonesia faces severe impacts, including the deaths of millions of people and vast virus transmission through a bad waste management system. Since the government applied lockdown in many regions, household waste increases and led to various problems. This research aims to explain household waste management intention during Covid-19, especially in a metropolitan city like Jakarta. This research adopts the Theory of Planned Behavior and examines the impacts of pandemic awareness, knowledge, and religion. Participants were involved in this study are 314 respondents. Questionnaires were gathered through emails, messenger applications, and social media. We use Structural Equation Modelling, particularly Confirmatory Factor Analysis, to analyze data and utilize LISREL 8.80. Results show that household waste management behavior can be encouraged through intention and pandemic risk awareness. Meanwhile, perceived behavioral control and household expenditures have to impact to intention to manage household waste. Moreover, government support also plays an important role in enhancing the intention of managing household waste. Therefore, social media and religious activities can be used to raise the level of risk awareness.

Authors: Noor Alfian , Nawangsari Lenny C.
Published: July 2021

Organizational sustainability is an important strategy in improving the organization. It is not only providing economic benefits but also intellectual capital of knowledge for PD Dharma Jaya employees. Some facts in the company environment show that the company mostly thinks of a turnover in making a profit, and there is only a small effort in a company organization to obtain sustainability by increasing the intellectual capital of its employees with knowledge. This is because the sustainability of the organization is considered voluntary. Because we need research on the factors that affect the sustainability of an organization, the research objective is the effect of intellectual capital on organizational sustainability with employee knowledge management as an intervening variable in PD Dharma Jaya. The research method used is explanatory quantitative with SEM-PLS. The sample in this study was 139 employees of PD Dharma Jaya. The sampling technique used in this study was saturated sampling (census). The results show that human capital and structural capital, as well as relational capital, have a positive and significant effect on Knowledge Management. Human capital has a positive and significant effect on organizational sustainability. Structural capital and relational capital have a negative and significant effect on organizational sustainability. Knowledge Management mediates the influence of human capital on organizational sustainability. It has a positive and significant effect. Knowledge Management mediates the effect of structural capital on organizational sustainability. It has a negative and significant effect. Knowledge Management mediates the effect of relational capital on organizational sustainability. It has a positive and significant effect. Based on interdimensional correlation matrix analysis, to increase employee engagement, it is recommended to maintain and improve indicators: (1) maintaining good relationships with customers and prospective customers; (2) strengthening knowledge management among employees; (3) developing new ideas in collaboration; and (4) continuously improving hard skills and soft skills.

Authors: Hou Guey-Lin
Published: July 2021

The aim of the present study was to assess the cumulative radiographic alveolar bone loss (CRABL) and yearly radiographic periodontal attachment loss (YRABL) of periodontal disease groups over 5 years or more. A total of 53 subjects, who had taken two sets of full-mouth standardized paralleling radiographs with separated periods of 5 years or more in Kaohsiung Medical University Hospital during 1981-2001, were collected for the past 20 years.

The radiographic alveolar bone levels at mesial and distal aspects of teeth were assessed by measuring the distance between cemento-enamel junction and alveolar bone crest using an electronic digimatic caliper (EDC) under a 3.5X magnified radiographs.

The results revealed that 1) patients with a periodic recall (3-4 times/yr.) showed a significantly lower loss rate than patients without periodic recalls; 2) mean CRPAL was highest in the generalized aggressive periodontitis (GAgP) group (5.52±3.27mm), then the chronic periodontitis (CP) group (4.82±3.47mm), and the localized aggressive periodontitis (LAgP) group (4.47±3.47mm) followed, and lowest in the periodontal healthy (PH) group (1.05±0.59mm); 3) mean YRPAL was the highest in the LAgP group (0.26±0.25mm/yr.), then the GAgP group (0.20±0.13 mm/yr.), and the CP group (0.12±0.09 mm/yr.) followed, and lowest in the periodontal healthy group (0.07±0.06 mm/yr.).

It was concluded that: 1) sites with more advanced alveolar bone loss are more likely to undergo further breakdown; 2) patients with a periodic recall showed a significantly lower alveolar bone loss rate and bone gain, irrespective disease groups; 3) mean CPBLs was highest in the GAgP group; mean YRABLs was highest in the LAgP.

Effective Power Allocation Using for Transmit Source In MIMO Relay Communication
Authors: Tran Hoai Trung
Published: July 2021

The Multiple Input Multiple Output (MIMO) systems using relays are of interest for high-speed radio communication systems. Currently, most of the articles are interested in the model of three nodes with purposes such as increasing the channel capacities (mutual information) or reducing the minimum mean square of error. This paper extends to more than one relay and is concerned with the maximum channel capacity. It is assumed that the channel matrices between source and relay as well as relay and receiver are random matrices; the relay precoders are also assumed to be random and known at the receiver. The article proposes that the Lagrange multiplier finding algorithm using the Newton – Raphson optimization method is more straightforward than the traditional finding algorithm using the first and second derivatives but still gives a higher channel capacity.

The Use of Froth Flotation for Selective Separation of Plastic Wastes from Soil

 

Kofi Moro and Dorothy A. Dechie

 

Abstract — In recycling of plastics, unless the goal is to form composites or materials having special properties, it is not advisable to mix plastics of different kinds because of the differences in their molecular weights and chain lengths. Hence, there is the need to separate these plastics when they are mixed before recycle can be done. This project investigated the selective separation of Polypropylene (PP), Polystyrene (PS) and Polyethylene terephthalate (PET) plastics out of soils using froth flotation. Pulverized samples were prepared from post-consumer plastic sources (PP, PS and PET) and soil and mixed uniformly to form a composite sample. The composite sample was subjected to froth flotation. Two tests were performed. A first test, where there was no addition of a depressant (tannic acid), and a second test, where there was addition of tannic acid to depress some of the plastics in order to selectively separate them. Recoveries from each test work indicated that, plastics are naturally hydrophobic and can be floated out of soils without modifying their surface properties. However, selective separations of the plastics were achieved when tannic acid was used to modify the surface properties of the plastic types.
Numerical simulation of measurements in radiation technologies

Published: July 2021

Radiation plays a very important role in the life of humans. Measurements in radiation technologies and radiation processes are very important. Usually measurements in radiation technologies are made with dosimeters of various types: solid state dosimeters, liquid dosimeters and gaseous dosimeters. Dose measurements are based on different principles: temperature increase, collection of electric charge, development of gases, accumulation of free radicals, trapping of electron in the matrix, color change, change of solution conductivity, radiation chemical oxidation, radiation chemical reduction. To measure absorbed doses the dosimetry system should be used which consists of dosimeters, measurement instrumentation, the calibration curve, reference standards and procedure for the system’s use.

 Computer processing power has increased rapidly and significantly over the past decades. Modern computers with proper software and mathematical methods allow to simulate very complicated processes, for example passage of ionizing radiation through the matter.

Article shows that GEANT4 can be used for numerical simulations to determine the absorbed doses, dose rates, and other values inside irradiated objects under radiation. The relative uncertainty is up to 11.8%. Simulation of radiation processing of complex objects can be performed with good accuracy. In order to use numerical simulations to measure radiation, metrological support should be developed.

The research aims to confirm the working hypothesis, identify the features of high-tech products of civilian use and analyze real “acting” projects implemented within the OI strategy. The analysis was carried out based on the information and systematic understanding of ideas presented in scientific articles, book chapters, etc., using induction and deduction (as a case study of Xerox, Fuji Xerox, Cisco, and Siemens companies), methods of formal and dialectical logic to understand the benefits from network cooperation and OI strategy. Thus, for example, it is shown that the OI concept in company strategies takes on the character of either institutional cooperation in the form of technological convergence or networking with the involvement of a wide range of participants in the latter: from students and university professors to companies and their employees, including foreign centers established by the interested parties, etc.
Inter-regional development in China: An assessment
Authors: Chan Sarah
Published: July 2021

China’s regional planning and development has been a key national priority since the start of economic reform and opening up. China’s regional development strategy has constantly evolved and has shifted to prioritizing integrated areas and mega-clusters to promote internal connectivity, increase urbanization and employment, and consequently, domestic consumption. This is distinct from past regional rebalancing initiatives, which were mainly aimed at reducing regional income gaps and relieving pressure from population flows to developed coastal regions. To support regional integration and sustain economic growth, institutional or structural policies to remove factor market distortions are just as necessary as increased investment in physical infrastructure, given that China’s domestic market is huge but highly fragmented. As China faces rising external geopolitical and global economic uncertainties, its regional development strategy will be to emphasize more on “dual circulation” to boost domestic demand and strengthen China’s supply chain resiliency, while still enhancing trade linkages with global markets to spur competition and support its industrial upgrading efforts.
Diferencias y sesgos de género en la financiación de la investigación: un enfoque dinámico
Authors: Cruz-Castro Laura
Published: July 2021

En general, las científicas consiguen menos fondos para investigar y tienen, con respecto a los solicitantes, menores tasas de éxito que los hombres. Este artículo revisa críticamente la literatura sobre las disparidades y sesgos de género en la financiación de la investigación, reconociendo la diversidad de hallazgos, y poniendo el énfasis en la necesidad de clarificación conceptual y rigor metodológico. Se adopta un enfoque dinámico con la premisa de que las diferencias en las tasas de solicitud y éxito en las convocatorias de proyectos de investigación se ven afectadas por diferencias previas y acumulativas, y a su vez influyen en la carrera posteriormente. Se revisa también el papel de las preferencias y de las expectativas individuales a la hora de competir, así como el proceso de evaluación y cómo las características de los evaluadores y de los procedimientos de las agencias pueden activar o desactivar mecanismos de sesgo.

Substrate Temperature Influence on Optical Properties of C60 Thin Films Within the Visible Range
Authors: Jalaukhan Ali H A , Hussein Mustafa M A
Published: July 2021

Fullerene thin films of about 200 nm thicknesses have been deposited by thermal evaporation method on soda lime glass at substrate temperature 303 and 403K under pressure about 10-5 mbar. This study concentrated on the influence of substrate temperature on the optical properties of C60 thin films within the visible range. Optical characterization has been carried out at room temperature using the absorption spectra, at normal incidence, in range (200-900) nm.

The absorption and extinction coefficients of the samples have been evaluated according to the variation in the UV- Visible spectrum. Increasing substrate temperature causes decreasing in optical band gap energy, for direct allowed transitions, and slightly changing in refractive index. This incident was due to the reducing of interatomic intervals, which may be correlating a decrease in the amplitude of atomic vibrations around their equilibrium sites.

The quality of groundwater is just as important as its quantity. The kinds and concentration of salts in groundwater depend on the environment, movement, and the source of the groundwater. During the field work, 20 samples have been collected from water wells from Al-Salman basin for two seasons represent wet and dry seasons in November 2017 and April 2018. After water well samples have been analyzed the Electrical conductivity values range from (2260 to 5500) Î¼S/cm for dry season and range from (2540 to 5630) Î¼S/cm for wet season, the Total dissolved solids values range from (1289 to 3582) ppm for dry season and range from (1710 to 3960) ppm for wet season, and pH values range from (7.11 to 7.3) for dry and wet seasons. The Hydrochemical classification which applied using Piper's Diagram revealed there are three type of water (sulphate type Ca+2 â€“ Mg+2 â€“ Cl- â€“ SO4, sulphate type Ca+2 â€“ Mg+2 â€“ Cl- - SO4, NaCl), and two water type by applying Chadha's diagram (sulphate type Ca+2 â€“ Mg+2 â€“ Cl- - SO4, Na+- Cl-), the variation of water type in the study area due to influence of Rus Formation which consists of anhydrite, and structure roles where made precipitation concentrate in Al-Salman depressions and streams flow faults that ended with playa.

Klebsiella pneumoniae is a pathogen of the Enterobacteriaceae family that causes healthcare-associated infections and has recently emerged as one of the most antibiotic-resistant organisms responsible for outbreaks in both community and healthcare settings. The aim of this study is to determine the resistance pattern of Klebsiella pneumoniae isolated from selected tertiary hospitals in Osun state, Nigeria. A total of 62 Klebsiella pneumoniae isolates were obtained from 1056 samples of urine, wound swab, ear swab, eye swab and other collection sites that were routinely submitted to the diagnostic laboratories of the selected tertiaryhospitals. Susceptibility to twelve (12) antibiotics (Oxoid) was determined using the Kirby Bauer disk diffusion method for the 62 isolates. Rate of resistance to carbapenems, fluoroquinolones, polymyxins, monobactams, cephalosporins, penicillin and phosphonic acid derivative are 29.03%, 47.84%, 29.03%, 46.77%, 50.80%, 93.55%, and 37.10% respectively. The isolates were mostly susceptible to carbapenems, especially, Imipenem with 74.19%. Highest resistance was to Penicillin (93.55%). The multiple antibiotic resistance (MAR) index revealed that 52 (83.87%) out of 62 isolates were multi-drug resistant. Increase in antibiotic resistance continues to be a problem amidst patients infected with Klebsiella pneumoniae which can be most likely attributed to increase in antibiotic misapplication, misuse and abuse which is most prevalent among youths. It is therefore of utmost importance that consistent monitoring of antibiotic resistance be done as it will assist in the appropriate selection of empiric antibiotic treatment in the proper setting.

Published: July 2021

In this research, the frequency-frequency interactions in chaotic systems has been experimentally and numerically studied. We have injected two frequencies on chaotic system where one of these frequencies is modulated with chaotic waveform and the other is untiled as a scanning frequency to find modulating frequency. It is observed that the Fast Fourier Transformation (FFT) peaks amplitude increased when the value of the two frequencies are matched. Thus, the modulating frequency could be observed, this leads to discover a new method to detect the modulating frequency without synchronization.

Published: July 2021

Always MRI and CT Medical images are noisy so that preprocessing is necessary for enhance these images to assist clinicians and make accurate diagnosis. Firstly, in the proposed method uses two denoising filters (Median and Slantlet) are applied to images in parallel and the best enhanced image gained from both filters is voted by use PSNR and MSE as image quality measurements. Next, extraction of brain tumor from cleaned images is done by segmentation method based on k-mean.  The result shows that the proposed method is giving an optimal solution due to denoising method which is based on multiple filter types to obtain best clear images and that is leads to make the extraction of tumor more precision best.
