Published: January 2022

Dermatophytosis includes all fungal infections caused by dermatophytes in humans. Some risk factors for the development of subtypes of dermatophytosis have been studied; however, large-scale epidemiologic studies on risk factors for total dermatophytosis are scarce. We investigated the risk factors of dermatophytosis using a nationwide study. Total 4,532,655 subjects with dermatophytosis aged between 20 to 40 years were examined using data from the Korean National Health Insurance Service from 2009 to 2018. Women showed a lower risk of development of dermatophytosis compared to men (hazard ratio [HR], 0.848; 95% confidence interval [CI], 0.843–0.853). Subjects with elevated waist circumference (HR, 1.057; 95% CI, 1.048–1.065), heavy drinking (HR, 1.053; 95% CI, 1044–1.061), engaging in mild-to-heavy exercise (HR, 1.071; 95% CI, 1.064–1.077) had a higher risk of dermatophytosis. In addition, subjects with body mass index (BMI) of more than 30 kg/m2 exhibited a higher risk of dermatophytosis (HR, 1.36; 95% CI, 1.342–1.378) compared to those with BMIs in the range of 18.5 to 23 kg/m2. In this study, the risk of developing dermatophytosis significantly increased in individuals with elevated waist circumference or high BMI. Lifestyle modifications, including weight management, are suggested to be important in preventing dermatophytosis.

Although the characteristics of the traveling 10-day waves (10DWs) above the middle stratosphere have been well explored, little research has been performed on the counterpart in the troposphere and lower stratosphere (TLS). In the present study, we use radiosonde observations and MERRA-2 data in 2020 to characterize traveling 10DWs in mid-latitudes in the TLS. Single-site observations in both hemispheres show that strong 10DW activities are always accompanied by strong eastward jets (10-13 km). MERRA-2 data indicates that in the troposphere the eastward-propagating modes with larger wavenumbers, i.e., E3, E4, E5 and E6 are dominant. While in the lower stratosphere the eastward- and westward-propagating modes with small zonal wavenumbers e.g., 1 and 2, are dominant. Further research on E3, E4, E5 and E6 modes in the troposphere of both hemispheres shows that all the wave activities are positively correlated to the background zonal wind. The refractive index squared reveal that a strong eastward jet is suitable for these four modes to propagate. However, just above the jet, the eastward wind decreases with altitude, and a thick evanescence region emerges above 15 km. E3, E4, E5 and E6 10DWs cannot propagate upward across the tropopause; as such this can explain why these four modes are weak or even indiscernible in the stratosphere and above. In the troposphere, E5 10DW at 32°S is the most dominant mode in 2020. A case study of the anomalously strong E5 10DW activity on May 12, 2020 indicates that the wave amplification resulted from the upward and equatorward transmission of wave energy flows. Moreover, the tropopause and equatorial region can prevent the propagations of wave energy flows of E5 10DW.

Published: January 2022

There is an increasing recognition of neurological manifestations from SARS-CoV-2 infection. Quantifications of such manifestations and their long-term dynamics in the general infected population are of essence in understanding the health and socioeconomic burden of neurological complications of COVID-19. Through rigorous empirical testing of over 800 volunteers, we present here repeated cross-sectional and longitudinal data that depict the trajectories of chemosensory functions, cognitive performances and depressive symptoms up to 1.5 years after acute COVID-19 in discharged patients with respect to non-infected controls. Overall, deficits in smell, taste and chemesthesis slowly resolved within about a year of discharge. Concerningly, cognitive impairments –– independent of elevated depressive symptoms and evident even in those with nonsevere disease –– showed no sign of improvement over time. In people over 50 years, COVID-19 was associated with a substantially increased risk for mild cognitive impairment. Our findings urge for cognitive and emotional interventions targeting COVID-19 convalescents.

Authors: Kishikawa Akihiro , Hamada Satoshi , Kamei Ichiro , Fujimoto Yosuke , Miyazaki Kazuhiro , Yoshida Motonobu
Published: January 2022

The cDNA library prepared from Lentinula edodes, Hokken 600 (H600), primordia was screened by using cDNA expressed specifically in Dictyostelium discoideum prestalk as a probe. Twenty-one clones, Le-Dd 1~21, were isolated from the L. edodes primordia cDNA library. Functional analysis of each gene was carried out by transformation into protoplast cells from L. edodes Mori 252 (M252) mycelia with the overexpression vector pLG-RasF1 of each gene because M252 protoplast cells were transformed with 11-fold higher efficiency than H600 cells. Transformants with the overexpression vector of Le-Dd10 formed a fruiting body at almost the same time as H600, a positive control, although M252, a negative control, did not form a fruiting body under culture conditions. This suggested that Le-Dd10 is involved in the formation of fruiting bodies. Single-strand conformation polymorphism analysis revealed that Le-Dd10 is located on No. 4 linkage group of L. edodes. The properties of Le-Dd10 products were investigated by Western blotting analysis using polyclonal antibodies against GST:Le-Dd10 fusion proteins. As a result, 56-kDa, 27-kDa, and 14-kDa protein bands appeared in primordial and fruiting body stages, although the expected molecular weight of the Le-Dd10 product was 50 kDa.

Published: January 2022

Background

Colorectal cancer (CRC) is among the leading cause of cancer-related morbidity and mortality worldwide. Aerobic glycolysis, as a metabolic hallmark of cancer, plays an important role in CRC progression. Enolase 3 (ENO3) is a glycolytic enzyme that catalyzes 2-phosphoglycerate into phosphoenolpyruvate, while its role in CRC is still unknown.
Methods

Bioinformatics analysis was performed to examine the expression changes and roles of ENO3 in CRC patients from public databases. Then, ENO3 expression was validated in CRC tissues using Quantitative real-time PCR (qRT-PCR), immunohistochemical (IHC) analysis, and western blot. Overexpression and silencing models were constructed using plasmid and lentivirus transfection. Cell viability, proliferation, and migration in vitro were applied to evaluate the protumoral effects of ENO3 on CRC. RNA sequencing and GO enrichment analysis of differentially expressed genes (DEGs) were performed to explore the underlying molecular mechanisms of ENO3 in CRC progression. The ATP and lactate production level were detected to assess cell glycolysis.

We report the synthesis of multiferroic BiFeO3 perovskite nanoparticles using the microwave combustion technique. Phase evolution is investigated by X-ray diffraction (XRD), which confirms that the formation of a secondary α-Bi2O3 phase with a monoclinic structure along with the existing rhombohedral (BiFeO3) structure. The average crystalline size has been found at 50 nm. The optical band gap was calculated from the Tauc’s plot it has been found 2.18 eV, as measured by diffuse reflectance spectroscopy (DRS). The appearances of Fourier transform infrared spectroscopy (FT-IR) absorption bands at 550 and 444 cm-1 were correlated to the rhombohedral stretching modes of bismuth ferrite nanostructure. The morphology observations using scanning electron microscopy (SEM) showed the formation of nanosized grains with pores. Energy-dispersive X-ray analysis (EDX) was done to confirm the extent of Bi3+, Fe3+, and O2- in the samples. The magnetization-Field (M-H) hysteresis curves recorded from the vibrating sample magnetometer (VSM) revealed the appearance of ferrimagnetic behavior at room temperature. The specific surface area characterized by N2 adsorption-desorption isotherm is found 44.86 m2 g-1 using Brunauer-Emmett-Teller (BET) technique. The as-fabricated BiFeO3 perovskite nanoparticles were investigated for their superior catalytic activity in two applications, which include (i) the conversion of glycerol to formic acid in a selective liquid phase batch reactor at atmospheric pressure. This bismuth-based nanoparticles exhibit as an efficient multifunctional catalyst with high conversion and selectivity efficiency around 99.2% and 98.5%, respectively, (ii) the photocatalytic degradation of rhodamine B under visible light irradiation is found maximum efficiency (99.9%), when a small amount of H2O2 was added during photocatalysis, indicating the samples possessed photo-Fenton like catalytic activity. Finally, we concluded that the BiFeO3 perovskite nanoparticles' high performance in future multifunctional devices is demonstrated by the simultaneous enhancement of catalytic and photocatalytic activities.
Comparison of deep vein thrombosis risks in acute respiratory distress syndrome Caused by COVID-19 and Bacterial Pneumonia: A Retrospective Cohort Study
Authors: Cui Na , Jiang Chunguo , Yang Chenlu , Zhang Liming , Feng Xiaokai
Published: January 2022

Background: High incidence of deep vein thrombosis (DVT) has been observed in patients with acute respiratory distress syndrome (ARDS) caused by COVID-19 and those by bacterial pneumonia. However, it is also important to differentiate between these two groups of patients. Study Design and Methods: We performed a retrospective cohort study to investigate the difference of DVT between the two independent cohorts of ARDS and eventually enrolled 240 patients, 105 of whom with ARDS caused by COVID-19 and 135 by bacterial pneumonia. We analyzed demographics and clinical characteristics for patients with and without DVT in these two cohorts and explored the main differences and similarities between them.Results: The 28-days incidence of DVT in COVID-19 cohort was higher than that in bacterial pneumonia cohort (57.1% vs 41.5%, P=0.016). Taking death as competitive risk, Fine-Gray test showed no significant difference in 28-day cumulative incidence of DVT between these two groups (P=0.220). Fine-Gray competing risk analysis showed an association between CK (creatine kinase isoenzyme)-MB levels, PaO2 (partial pressure of arterial oxygen)/FiO2 (fraction of inspired oxygen) ratios, D-dimer levels and DVT in COVID-19 cohort and an association between serum creatinine levels, IMV, and DVT in bacterial pneumonia cohort. The sensitivity and specificity of corresponding receiver operating characteristic curve originating from the combination of CK-MB levels, PaO2/FiO2 ratios and D-dimer levels ≥ 0.5 µg/mL was not inferior to those of the Padua prediction score and the Wells score for screening for DVT in COVID-19 cohort.Conclusions: Compared with patients with ARDS caused by bacterial pneumonia, the incidence of DVT is higher by logistic model in patients with ARDS caused by COVID-19, and the risk factors for DVT are completely different. Our novel prediction model can aid early identifying patients with high risk for DVT.

Published: January 2022

Background: PDZ-binding kinase/T lymphokine-activated killer cell-derived protein kinase (PBK/TOPK) is a potential prognostic indicator for patients with breast cancer. The objective of the present study was to explore the relationship between PBK/TOPK expression and clinicopathological indicators as well as the survival of patients with breast cancer.Methods: Immunohistochemical staining was used to detect the expression of PBK/TOPK in 202 cases of breast cancer tissues. The relationship between PBK/TOPK and clinicopathological parameters was evaluated using Spearman's rank-order correlation. The difference in PBK/TOPK expression among different molecular types was analyzed with the chi square test. Kaplan-Meier analysis was used to create a survival curve and the log rank test was used to analyze the overall survival (OS) and disease-free survival (DFS). Prognostic correlation was assessed using univariate and multivariate Cox regression analyses.Results: Among 202 breast cancer samples, PBK/TOPK was expressed ('+' and '++') in 182 samples (90.1%). In addition, the histological grade, TNM stages, lymph node metastasis, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2), and Ki-67 were positively associated with PBK/TOPK expression. With regard to the molecular type, the expression of PBK/TOPK is different. The expression level of PBK/TOPK was negatively correlated with both the OS and DFS of breast cancer patients. The difference in the above results is meaningful (P<0.05).Conclusions: PBK/TOPK is over-expressed in breast cancer and the expression is closely related to the clinicopathological characteristics of the disease. Breast cancer patients with high expression of PBK/TOPK have a poor prognosis. Therefore, health care providers can optimize breast cancer management using this indicator.

The study was aimed to analysis determinants of inorganic fertilizer use intensity on cereal crops among small holders in Toke Kutaye District, West Shewa Zone, Ethiopia. Correctional data were collected from 156 respondents using two stage random sampling methods. Data analyses were carried out using descriptive statistics and Double hurdle model. Result of the first hurdle reveals that out of twelve explanatory variables Sex ,Education, Off/non-farm income, Land size and Improved seed were determine positively whereas Age and Distance from nearest market determine small holders use of inorganic fertilizer negatively. The result of second stage of double hurdle model indicate that, out of twelve explanatory variables Sex, family size and Land size were positively affect extent (intensity) of inorganic fertilizer use whereas Age and Distance of household from nearest market determine use intensity negatively. Therefore, these results implied that there is a room to increase inorganic fertilizer use intensity on cereal crop productions. Hence, Farmers capacity to purchase this input beginning from lower income farmers to model farmers should be acknowledged; and should be designed the means to address those who have no ability to use inorganic fertilizer in their own farm through diverse development interventions.
Temperature, carbon dioxide and methane
Authors: Hambler Clive , Henderson Peter A.
Published: January 2022

1) Globally-representative monthly rates of change of atmospheric carbon dioxide and methane are compared with global rates of change of sea ice and with Arctic and Antarctic air temperatures. 2) Carbon dioxide is very strongly correlated with sea ice dynamics, with the carbon dioxide rate at Mauna Loa lagging sea ice extent rate by 7 months. 3) Methane is very strongly correlated with sea ice dynamics, with the global (and Mauna Loa) methane rate lagging sea ice extent rate by 5 months. 4) Sea ice melt rate peaks in very tight synchrony with temperature in each Hemisphere. 5) The very high synchrony of the two gases is most parsimoniously explained by a common causality acting in both Hemispheres. 6) Time lags between variables indicate primary drivers of the gas dynamics are due to solar action on the polar regions, not mid-latitudes as is conventionally believed. 7) Results are consistent with a proposed role of a high-latitude temperature-dependent abiotic variable such as sea ice in the annual cycles of carbon dioxide and methane. 8) If sea ice does not drive the net flux of these gases, it is a highly precise proxy for whatever does. 9) Potential mechanisms should be investigated urgently.

REVISITING JAVANESE ISLAM
Authors: Kabir Gedong Maulana
Published: January 2022

This article tends to revisiting Javanese Islamic studies. This study began from the European travelers’ period who noted some aspects of society such as the religious life. Those notes show the negative label that is addressed to the Javanese religious practices. These negative labels are often reproduced in Javanese Islam studies to this day. This article argues that the negative labels in Javanese Islamic studies tend to be misrepresentative. These kinds of results cannot be separated from certain paradigms in religious studies. There are two paradigms in the study of religion which are discussed in this article. First, the world religion paradigm. This paradigm, consciously or not, is often used in Javanese Islamic studies. The implication is Javanese religious practices are often portrayed as animist, syncretic, and so on. Second, the indigenous religion paradigm. This article elaborates this paradigm because of its potential in understanding Javanese Islamic religious practice more properly. The basis of this paradigm is intersubjective relation with ethical commitment, responsibility, and reciprocity.

Studies into mitochondrial сomplexomes in various organisms provide an insight into the native organization of proteins and metabolic pathways in the organelles of the subject under study. “Complexome” is a relatively recent concept describing the proteome of protein complexes, supercomplexes, and oligomeric proteins. Complexome analysis is performed using current electrophoretic and mass spectrometric techniques, in particular, by two-dimensional electrophoresis (2D BN/SDS-PAGE) in combination with mass spectrometry (MS). Unlike 2D IEF/SDS-PAGE, this method enables analysis of not only hydrophilic proteins of the mitochondrial matrix, but also membrane proteins and their associations, thus expanding the possibilities of studying the organelle proteome. In the present work, the complexome of etiolated pea shoots was studied for the first time using 2D BN/SDS-PAGE followed by MALDI-TOF MS. To this end, 145 protein spots excised from the gel were analyzed; 110 polypeptides were identified and assigned to different functional groups. A densitometric analysis revealed that the major protein group comprised the enzymes of the mitochondrial energy system (1), accounting for an average of 43% of the total polypeptide content. The remaining 57% was primarily distributed among the following functional categories: pyruvate dehydrogenase complex and citric acid cycle (2); amino acid metabolism (3); nucleic acid processing (4); protein folding (5); antioxidant protection (6); carrier proteins (7); other proteins (8); proteins having unknown functions (9). The obtained data indicate the complex organization of the pea proteome. In addition to the enzymes of the OXPHOS system, the proteins of other functional categories are found to form supramolecular structures. It is suggested that the presence of proteins from other cellular compartments may indicate the interaction of mitochondria with the enzymes or structures of corresponding organelles. In general, the obtained data on the pea complexome represent a kind of a mitochondrial “passport” that reflects the native state of the proteome of organelles corresponding to their physiological status.
IR spectroscopy for analysing solvent extraction efficiency of oil extracts
Authors: Zholnerkevich V. I. , Grushova E. I.
Published: January 2022

Solvent extraction is a method for purifying oil extracts, which are used as oil-plasticisers for industrial rubber goods, from cancerogenic hydrocarbons. The efficiency of this method is mainly determined by the selectivity and solvent properties of a separating agent. However, when carrying out a comparative analysis of promising extraction methods, it is necessary to use real-time methods for studying the composition of the resulting products. The purification efficiency of oil extracts from polycyclic aromatic components, including carcinogenic hydrocarbons (benzo[a]pyrene, benzo[e]pyrene, benzo[a]anthracene, chrysene, benzo[b]fluoranthene, etc.), was evaluated depending upon the nature of selective solvents. The structure-group composition of the purified oil extracts and those at the second-stage of purification was determined by FTIR spectroscopy. It was found that the extraction efficiency of the studied solvents towards polycyclic aromatic hydrocarbons from oil extracts increases in the following order: dimethyl sulfoxide < N-methylpyrrolidone + 10 wt% ethylene glycol <N-methylpyrrolidone +50 wt% triethylene glycol. When using a solvent comprising N-methylpyrrolidone + 50 wt% triethylene glycol, the proportion of polyalkyl-substituted and condensed aromatic structures in the purified oil extract decreases by 16.8%; the oil extract yield increases by over 25 wt% in contrast to extraction with N-methylpyrrolidone + ethylene glycol mixture, which meets the requirements of the European Union for oil extract purification (Directive No. 2005/69/EC). Therefore, we recommend the solvent comprising N-methylpyrrolidone + 50 wt% triethylene glycol for purifying oil extracts from components having a technogenic impact on the environment and human health and IR spectroscopy for efficiency assessment of solvent extraction of oil extracts.
Divisão do reservatório superior, uma estratégia de redução de custos para sistemas de reuso em edifícios residenciais?
Authors: Matias Netto Diogo Bastos , Teixeira Marcos Alexandre
Published: January 2022

Dado que muitas edificações dividem sua caixa d'água superior em duas células, avaliou-se a possibilidade de manter uma com água de reuso, concentrando toda a reserva técnica de incêndio (RTI), e a outra concentrando a água potável. Essa opção de redução de custo teve sua viabilidade técnica analisada (frente à legislação aplicável), e seu desempenho econômico comparado com projeto padrão (reservatório adicional). Foram considerados dois cenários de reuso: água cinza proveniente do chuveiro e torneira do banheiro alimentando descargas e, captação de toda a água cinza do apartamento alimentando descargas, máquina de lavar roupa e limpeza das áreas comuns. Considerou-se edificação residencial de 16 andares com quatro unidades por andar (perfil R16-N CUB). O trabalho analisou a legislação e normas aplicáveis, os custos, assim como impactos na instalação no topo do edifício (ex. reservatório adicional e mudança nos barriletes). Os resultados indicam que foi possível a adaptação no uso das células atendendo-se às normas e legislações aplicáveis. Para o primeiro cenário de reuso (água cinza apenas do banheiro) com 3,48 R$/m3 de custo da água, tem-se uma TIR de 5,12% para projeto padrão (armazenamento em outra caixa d'água), sendo aumentada para 19,28% com o projeto de redução de custo (armazenamento em uma das células da RTI com água de reuso), elevando o VPL a valores positivos. No segundo cenário (utilização de toda água cinza da edificação) chegou-se a TIR de 20,74%, para o projeto padrão, e para 49,86% para o projeto com redução de custo (ambos VPL positivos).
Analysis of XLPE cable parameters subject to thermo aging
Authors: Buev S. A.
Published: January 2022

Modern marine vessels use electrically driven rudders; cruise liners, gas carriers, tankers are equipped with Azipod systems manufactured by the Swedish-Swiss company ABB. Gondola-type propellers make it possible to break ice when the vessel is moving astern, therefore such vessels are used for work on the Northern Sea Route, in particular, when working on the Yamal LNG project. The 22MW Azipod propulsion system rotates 360° and enables difficult maneuvering without the assistance of tugs. When operating such propellers, powerful diesel generators are installed on the ship. For the transmission of electricity, ship cables are used, which are subject to increased requirements that meet the standard of the International Electrotechnical Commission. Modern marine vessels are equipped with XLPE or EPDM insulated cable lines; industrial production of these cables is carried out in the Russian Federation. In the course of the study, a method for auditing the state of insulation has been considered based on an assessment of the change in the tangent of the angle of dielectric losses in the process of thermal aging of the cable of the PvBPng(A)-HF brand. Measurements of the tangent of the dielectric losses' angle have been carried out with a Tangens-2000 insulation parameter meter.
Production technology and quality assessment of milk shakes for baby food with vitamin complex enrichment
Authors: Boyarshinova E. V.
Published: January 2022

Diversification of dairy products for baby food is a topical trend in the development of the dairy industry. In the process of producing an ultra-heat-treated (UHT) milkshake, milk with a mass fraction of fat 3.5 %, skim milk with a mass fraction of fat 0.5 %, fruit filling "Cherry" and a vitamin premix are used. The technological process of production includes the acceptance of raw materials, assessment of their quality in accordance with regulatory documents; heat treatment of raw milk; preparation of a normalized mixture; adding ingredients. The prepared mixture is sent for deaeration to a flow-through apparatus, then to a homogenizer, where it is subjected to ultra-pasteurization at a temperature of 136 ± 2 °C with a holding time of 4 ± 1 s. The final stage of cocktail production is packaging and intermediate storage. The resulting product was tested in the laboratory for organoleptic and physicochemical indicators. During the experiments, it has been found that the taste, smell, colour, appearance and consistency meet the requirements of state standards. The content of protein, fat, carbohydrates, calcium and titratable acidity are within acceptable values; the content of vitamins A, D, E, B is higher than the minimum values. The research results on safety indicators meet the requirements of technical regulations. Antibiotics, GMO-derived materials and preservatives are not found in the product. The energy value of the baby milk shake is 63.7 kcal (266.6 kJ/100 g of product).

Published: January 2022

The search for equivalent flavoring sugar substitutes of a non-sugar nature is an urgent direction in the development of the technology of flour confectionery products. In the course of research, a gingerbread recipe has been developed with a partial replacement of the prescription sugar with a 15 % solution of sucralose in glycerin, which most closely correspond to the organoleptic characteristics (taste, smell, texture) of traditional flour confectionery products. The results of the organoleptic evaluation of coded prototypes of gingerbread with the involvement of experts have shown that a decrease in sugar concentration by 25 % does not lead to a statistically significant change in organoleptic parameters in comparison with control samples. Substitution of more than 30 % sugar leads to an increase in the plasticity of the dough complicating the operation of the dosing mechanisms; at the same time, the taste of the products changes (these changes are noted during the tasting assessment); their consistency becomes denser. In the process of research, the stability of the quantitative and qualitative properties of gingerbread during storage has been proved. Experimental samples of gingerbread with 25 % reduced sugar content retain all the indicators established by GOST for their storage for 90 days without statistically significant changes. The decomposition of sucralose in the manufacture of the dough is 0.1 %, in the baking process - 2.6 %, during storage for 120 days - 6.7 % (of the loaded product). The developed recipe allows enterprises to expand the range of confectionery products with reduced sugar content.

This paper examines the special characteristics of tourism development on the Adriatic islands, focusing on Hvar Town, the largest town and port on the island of Hvar and its busiest destination. The research was carried out using the method of semi-structured interviews. A total of 30 interviews were conducted with the local residents (mostly employed in the tourism sector) and temporary/seasonal visitors. The intention was to learn about the current state of tourism in the town and look at the possible scenarios for the future development of sustainable tourism, based on its three inter-connected aspects: environmental, economic and socio-cultural. The research also considered the influence of various tourism actors on the development, the possibilities of agritourism, the role and importance of cultural tourism and, finally yet importantly, the impact of the Covid-19 pandemic on the last year's drastically shortened summer season. The results show that mass tourism (and its subset party tourism) have dominated the tourist offer since 2000 onwards, changing the reputation of Hvar as the elite travel destination or the family holiday destination it used to have before.
Memoirs of the Battle of Okinawa: From the Perspective of ‘Mabuigumi’
Authors: Kim Junghee
Published: January 2022

This article focuses on the story ‘Mabuigumi’ (‘Spirit Stuffing,’ 1998) by Medoruma Shun, a contemporary writer of Okinawan descent. The story explicitly depicts the history of the Battle of Okinawa and the people who were traumatized by the war. First, this article demonstrates that landscapes and living things evoke memories of the war and people, and they play a significant role in showing that people’s present lives remain threatened. Second, the article conjectures that an āman (a hermit crab) represents Okinawa, which was traumatized by the mainland, and shows that Uta (the protagonist) is burdened by the guilt of her own survival. In addition, it considers the love of a mother (Omito) and son (Kōtarō) for each other. Third, this article illustrates that the history of the mainland was decentralized through visual expressions of personal memories of war. The history of mainland Japan does not regard the fact that Japanese soldiers killed Okinawans during the Battle of Okinawa. History, as officially narrated by the Okinawans, changes its narrative content depending on the shifting relationship between Okinawa and the mainland. This work relativizes and decentralizes the official historical narratives of the mainland and Okinawa through repressed personal memories of the war.

Authors: Atkinson Connor
Published: January 2022

Phthalocyanine molecules have the potential to be used in select Dye Sensitized Solar Cells (DSSCs) and Luminescent Solar Concentrators (LSCs), due to UV-Vis absorbance in the 300-450 (nm) Soret Band, corresponding to π HOMO-1 to π* LUMO transition and 550-690 (nm) Q-band, corresponding to π HOMO to π* LUMO transitions. In this study Tetranitro Zinc (II) Phthalocyanine is synthesized via base catalysis before the product is characterized via IR, 1H NMR & UV-Vis analysis. Assessing the desirability of the Tetranitro Zinc (II) Phthalocyanine as a solar organic semiconducting dye in DSSCs and LSCs. The desirability is assessed by novel computational DFT calculations, of the aggregation binding mode to deduce if Aggregation-Caused Quenching (ACQ) is occurring in the aggregated sample. ACQ is known to reduce DSSCs and LSCs generation of useful photo-active current. Aggregation-Caused Quenching (ACQ) is mathematically indicated in Phthalocyanine aggregation and Tetranitro Zinc (II) Phthalocyanine’s desirability is assessed for further use in DSSCs and LSCs.

O presente artigo tem o intento de apresentar a construção da Política de Arte e Cultura (PAC) do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul (IFRS), mostrando o cenário para sua implementação, as diretrizes que orientam suas metodologias de elaboração e os indicadores para essa implementação. A PAC teve sua fundamentação baseada no campo das Políticas Culturais nas Instituições de Ensino Superior (IES) e na Lei de Criação dos Institutos Federais, considerando, em sua composição, as dimensões do ensino, da pesquisa e da extensão. A finalidade de sistematizar e publicizar esse processo é compartilhar o caminho percorrido e sinalizar os movimentos que evidenciaram e problematizaram as questões relacionadas ao campo da Arte e da Cultura em seu contexto cotidiano e político-institucional. Aprovada em 2020, a Política resultou em um marco no direcionamento da instituição, pautando as decisões de cada campus e estabelecendo um espaço reconhecido para as artes e a cultura, através da regulamentação constante do documento. O texto está estruturado de modo a contextualizar e analisar a política e suas metodologias de elaboração, bem como a estrutura prevista para sua implantação junto aos campi e à reitoria, considerando-se os desafios inerentes ao processo. A aprovação do documento impulsionou a mobilização dos agentes institucionais para a realização de ações promotoras da valorização e da afirmação artístico-cultural no imaginário e nas práticas cotidianas do IFRS.
A PROFISSIONALIZAÇÃO EM TEATRO NA EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA NO BRASIL
Authors: Costa Santos Raina , Ramos Artuso Alysson , Lemos Junior Wilson
Published: January 2022

O Teatro contempla, pela natureza de suas práxis, uma formação integral dos sujeitos, e possibilita por meio da fruição estética, o pensamento crítico e a compreensão de como afetamos e somos afetados pelas relações que temos com o mundo. É inerente ao trabalho teatral a constante pesquisa e renovação do processo educativo que cada trabalho possibilita, tanto para quem produz, quanto para quem assiste. E assim, ao pensar uma formação profissional para o Teatro, não se pode considerá-lo apenas como uma preparação para um trabalho, mas respeitar a sua natureza sensível que tem como matéria-prima a própria vida. Com isso, o presente artigo buscou fazer uma contextualização do tema da profissionalização em Teatro dentro da Educação Profissional e Tecnológica (EPT) e relacionar-se com os conceitos de ensino formal e não-formal no contexto da EPT. Buscou-se fazer uma revisão da literatura sobre o histórico da profissionalização do Teatro no Brasil e, para fins de recorte da pesquisa, foram priorizados os marcos históricos referentes à institucionalização do ensino de Teatro visando à formação profissional de novos artistas. No decorrer da pesquisa observou-se que, no âmbito da associação da EPT e da profissionalização em Teatro, nos trabalhos pesquisados e nas legislações, há carência de estudos e levantamentos específicos mais aprofundados, como sugestão de trabalhos futuros. O Teatro, e a área da cultura em geral, sofreram ao longo dos anos com políticas públicas insuficientes para atender as suas demandas. Assim, para esse trabalho foram elencadas as principais legislações que incidem no Teatro em três áreas: na educacional, na formação profissional e na atuação profissional dos artistas e técnicos de Teatro. Este é um recorte da pesquisa de mestrado intitulada “Como se fazem artistas? Em busca de uma webcartografia para a profissionalização em Teatro na educação profissional e tecnológica”.

Nos últimos anos, Umuarama teve uma expansão significativa da mancha urbana. A falta de planejamento urbano pode causar vários problemas quanto à sustentabilidade, entre eles estão as alterações climáticas que causam ilhas de calor. O objetivo dessa pesquisa foi identificar se é possível relacionar as variáveis climáticas com a expansão da mancha urbana de Umuarama entre os anos de 2005 a 2020 por meio da obtenção de dados de uma única estação meteorológica. Foi utilizado o método de estudo de campo, no qual foram coletados dados meteorológicos desse período, organizados em tabelas e gráficos, elaborados mapas do histórico da mancha urbana por meio da análise de imagens de satélite, além da análise de dados do IBGE. Entre 2010 e 2020 a cidade teve aumento de 11,74% dos habitantes. O perímetro urbano teve maior expansão entre 2011 e 2020, e tende a crescer no sentido nordeste e sudeste. Seu acréscimo de área territorial foi de, aproximadamente, 64% entre 2005 e 2020. Quanto às variáveis climáticas, durante o período analisado a radiação solar média anual teve ligeiro acréscimo; a temperatura média anual do ar apresentou uma tendência de queda desde 2005; a umidade relativa média anual do ar passou por várias oscilações, com maior porcentagem em 2015 e menor em 2008; e a velocidade média anual dos ventos diminuiu ao longo do período. A queda da velocidade dos ventos pode estar relacionada com o aumento de barreiras físicas formadas por edificações. Embora a temperatura média mensal do ar tenha diminuído, é comprovado que a urbanização causa aumento das temperaturas locais. Sugere-se analisar os dados máximos e mínimos diários. Para correlacionar as mudanças mesoclimáticas com a expansão urbana, o ideal é analisar dados de outras estações meteorológicas, portanto, conclui-se que Umuarama necessita de outra estação meteorológica para estudo adequado de mudanças mesoclimáticas.
FERRAMENTAS ESTATÍSTICAS E DE GEORREFERENCIAMENTO PARA O ESTUDO DO ALCANCE INSTITUCIONAL E DA EVASÃO ESCOLAR – UMA PROPOSTA DE METODOLOGIA
Authors: Artuso Alysson Ramos , Pires Daniel da Rosa Salles , Rodrigues Larissa de Oliveira
Published: January 2022

Apresentamos uma forma de estudar o alcance institucional e a evasão escolar com o auxílio de ferramentas estatísticas e de georreferenciamento. A proposta é uma metodologia em cinco passos, desde a definição das variáveis até o debate dos resultados com a comunidade escolar. De modo a ilustrar a metodologia, foi feita uma aplicação no Instituto Federal do Paraná, campus Colombo. A proposta foi capaz de identificar modificações no alcance institucional e na evasão escolar ao longo dos anos em relação a alguns estratos e descartar a influência de outros. Algumas perguntas passíveis de serem respondidas são: O alcance da instituição tem mudado ano a ano? Há diferenças no alcance em relação aos cursos? A evasão é menor quando os estudantes entram na instituição por processo seletivo em vez de sorteio? As cotas de ingresso influenciam na evasão? A distância que o estudante precisa percorrer para chegar ao campus está relacionada com a evasão? Entre os resultados encontrados, temos que: (a) não há uma clara relação entre a localização geográfica e a evasão; (b) há algumas regiões do município, em especial de áreas mais vulneráveis, que o IFPR Colombo não consegue atingir; (c) bolsas e auxílios ajudam a evitar e evasão; (d) a forma de ingresso não é fator preponderante na evasão. Por fim, reiteramos a necessidade da discussão dos dados com a comunidade escolar para a tomada de decisão, pois defendemos que, embora a ciência e a tecnologia sejam comumente vistas como legitimadoras de decisão, é preciso trazer a dimensão humana e social para o processo decisório, inclusive discutindo valores e visões de mundo que o permeiam.
