A FLECHA DO ESPAÇO-TEMPO E A TOTALIDADE EM TOTALIZAÇÃO
Authors: Camargo Luis Henrique
Published: October 2021

Este artigo, que nasce de uma revisão teórico-conceitual atravessou diferentes campos do saber, em uma proposta transdisciplinar, tem como objetivo apresentar a flecha do espaço-tempo como elemento fundamental para a compreensão analítica dos fluxos de energia e matéria que sistemicamente integram a sociedade com seu meio natural, alterando diretamente a evolução planetária. Para escolha do método, rejeitamos o pensamento cartesiano-newtoniano, por entender que a sua fragilidade conceitual fragmenta o espaço em relação ao tempo e que se baseia em um universo máquina preciso e linear. Por isso, a pesquisa optou pela leitura da realidade sistêmica-quântica. Essa epistemologia, por sua vez, proporcionou a compreensão de fenômenos como a integração do espaço com o tempo, a imprevisibilidade, a interconectividade e a auto-organização. No desenvolvimento da pesquisa e após um debate conceitual inicial, visando consolidar nossa hipótese, foi proposto um cotejamento entre solos agrícolas ecológicos e não ecológicos. Essa escolha se deu devido à atividade agrícola ser a primeira, após o surgimento do Holoceno, a gerar grandes impactos sobre o ambiente. Dessa forma, percebendo a importância do lugar e de suas relações integradas com a natureza, foi demostrado que solos não ecológicos geram grande instabilidade nos sistemas naturais que o circundam, podendo criar processos irreversíveis aos mesmos. Esse mecanismo se deve a esse tipo de manejo se utilizar de grande quantidade de energia externa com maquinário, agrotóxicos, irrigação artificial, alteração do processo de produção, dentre outras questões. Por essas razões, as áreas de agricultura não ecológicas acabam emitindo grandes instabilidades para as outras esferas naturais que a circundam, podendo gerar processos irreversíveis e que agora, ao lado de outros processos, demonstram a evolução do planeta em um novo patamar de organização ecológico-geológico conhecido como Antropoceno. Por sua vez, solos ecológicos que possuem sistemas em equilíbrio próximo ao natural, por não se vincularem a grandes fluxos energéticos, acabam mantendo antigos padrões de organização, não colaborando para efetivar grandes alterações no desenvolvimento da(s) flecha(s) do espaço-tempo do planeta.

Published: October 2021

Background: Chronic wounds of the lower extremities are challenging to treat. Recently, honey-based dressings have been shown beneficial effects in diabetic foot ulcers and venous ulcers. Here, we compared Medihoney alginate with a standard alginate dressing in lower extremity chronic wounds.Methods: We performed retrospective chart reviews of 37 patients between January 2019 and January 2021 with chronic lower extremity wounds who were treated with an Algisite M dressing (group A) or a Medihoney alginate dressing (group B). Microorganisms isolated from wound cultures, weekly decrease in wound area over 4 weeks, the number of patients who achieved complete wound closure, and the amount of time required for wound closure were compared between the two groups. Results: Sixteen patients were assigned to group A and 21 to group B. The isolated microorganisms were confirmed as methicillin-susceptible Staphylococcus aureus most commonly, followed by methicillin-resistant S. aureus. Wound area decreased from 12.71 to 2.34 cm2 in group A and from 14.07 to 1.71 cm2 in group B (P<0.05). Seven patients achieved complete wound closure in group A (43.75%) and 15 patients in group B (71.43%). Mean duration of wound closure was 36.31 days in group A and 34.62 days in group B.Conclusion: Considering the more rapid decrease in wound area in group B, application of a honey-containing alginate dressing to lower extremity chronic wounds, especially those infected with antibiotic-resistant bacteria, was proved to be a good treatment option.
Three-Dimensional Computed Tomography Follow-Up on Spontaneous Bone Healing after Excision of Periorbital Dermoid Cyst: A Case Report
Authors: Park Hannara , Seong Jaemin , Park Hyochun , Yeo Hyeonjung
Published: October 2021

Dermoid cysts are among the most common periorbital and orbital tumors presenting in childhood. Several studies have shown that dermoid cysts may deform adjacent bones; however, few studies have followed the course of bone regeneration after the excision of a cyst. We report a case of a 29-month-old female infant who presented with a palpable mass over her right lateral eyebrow. Ultrasonography findings suggested a dermoid cyst, and computed tomography revealed a 2.1-cm round bony defect in the right zygoma. After surgical excision of the dermoid cyst, we successfully applied fibrin sealant to eliminate the dead space. Pathological findings showed nodular lesions with flat cystic walls containing lamellated keratin and sebaceous glands, supporting the diagnosis of dermoid cyst. At 6 months postoperatively, a follow-up computed tomography scan confirmed complete recovery of the bone defect in the right zygoma.
Disseminated Mycobacterium avium Complex Infection Causing Multiple Skull Defects in an Immunocompetent Patient: A Case Report
Authors: Choi Jun Ho , Oh Seong Jin , Hwang Jae Ha , Kim Kwang Seog , Lee Sam Yong
Published: October 2021

Mycobacterium avium complex (MAC) infection mainly causes pulmonary disease. However, in 20% to 30% of cases, it also induces various extrapulmonary diseases. Disseminated MAC infection occasionally occurs in immunocompromised patients but very rarely in immunocompetent patients. An 80-year-old immunocompetent woman presented with multiple chronic wounds on the scalp that had not improved despite prolonged treatment. A scalp abscess caused by disseminated MAC infection 4 years ago had gone through repeated cycles of improvement and aggravation despite continued use of anti-mycobacterial agents and active wound care. Enhanced brain computed tomography and magnetic resonance imaging revealed multiple skull defects and abscesses invading the dura mater. Under general anesthesia, the infected scalp skin and bone were sufficiently removed, and the bone and soft tissue defects were repaired with cranioplasty using a titanium mesh plate and local flap. As exemplified in this case, multiple chronic wounds unresponsive to treatment need to be screened for MAC infection. As chronic MAC infection in the scalp can cause skull destruction and brain infection, it needs to be treated aggressively at an early stage to prevent serious morbidity and mortality. Effective MAC infection management involves adequate medication, regular follow-up imaging, and active surgical procedure.

Published: October 2021

Objectives: First, to examine the predictive performance for placental
dysfunction related stillbirths of the competing risks model for small
for gestational age (SGA) fetuses based on a combination of maternal
risk factors, estimated fetal weight (EFW) and uterine artery
pulsatility index (UtA-PI); and second, to compare the performance of
this model to that of stillbirth-specific model utilizing the same
biomarkers and to the Royal College of Obstetricians and Gynecologists
(RCOG) guideline for the investigation and management of the SGA fetus.
Design: Prospective observational study. Setting: Two UK maternity
hospitals. Population: 131,514 women with singleton pregnancies
attending for routine ultrasound examination at 19-24 weeks’ gestation.
Methods: The predictive performance for stillbirth achieved by three
models was compared. Main outcome measures: Placental dysfunction
related stillbirth. Results: At 10% false positive rate, the competing
risks model predicted 59%, 66% and 71% of placental dysfunction
related stillbirths, at any gestation, at <37 weeks and at
<32 weeks, respectively, which were similar to the respective
figures of 62%, 70% and 73% for the stillbirth-specific model. At a
screen positive rate of 21.8 %, as defined by the RCOG guideline, the
new model predicted 71%, 76% and 79% of placental dysfunction related
stillbirths at any gestation, at <37 weeks and at
<32 weeks, respectively, and the respective figures for the
RCOG guideline were 42%, 44% and 40%. Conclusion: The predictive
performance for placental dysfunction related stillbirths by the
competing risks model for SGA was similar to the stillbirth-specific
model and superior to the RCOG guideline.

Authors: Dastgeer Ghulam , ur Rehman Atiq , Ali Asghar Muhammad
Published: October 2021

This research article presents a comparative analysis of three major methods of mediation analysis i.e., Baron and Kenny, Sobel, Hayes indirect effect with bootstrap using PROCESS macro and Structural Equation Modeling (SEM). It discusses common issues associated with mediation analysis and common mistakes committed in the selection and application of method and in the interpretation of results. In this article we have developed and tested a variety of models including simple mediation, parallel mediation, and serial/sequential mediation models. We have used a research model drawn from management field which includes two independent variables (i.e., organization justice and corporate social responsibility), two dependent variables (i.e., employee wellbeing and organization performance) and two mediating variables (i.e., organization trust and organization culture). The article illustrates that bootstrapping has an advantage over Baron and Kenny method or with Sobel test. Besides, it has high statistical power and better control on type-I error. It produces better results even when data lacks the property of normal distribution. The article has many practical implications. More particularly for management researchers, it provides an in-depth understanding of how to correctly conduct mediation analysis.

Dengan hadirnya VAR jelas akan mengurangi angka keputusan kontroversial dari seorang wasit.
Numerical Study of Lymph Mechanics
Authors:   , Watson Daniel J.
Published: October 2021

Methods taken from engineering and computer science were applied to the lymphatic system. Starting with a 3D analysis of a single subject-speciﬁc lymphatic valve. A mechanism was presented to explain previous experimental results showing the eﬀect of trans-mural pressure on the pressure required to close lymphatic valves. The impor-tance of wall motion in future FSI studies of lymphatic valve dynamics were identiﬁed. Previous approaches to lumped modelling of the lymphatic system were considered and modiﬁcations were proposed. A less-idealised valve model, incorporating trans-mural dependent bias, was proposed as well as a method of allowing self-organised contrac-tion through a stretch-dependent frequency of contraction. A network of the superﬁcial lymphatics of the upper-limb was reconstructed from an anatomical sketch. The net-work was used in conjunction with the lumped model to produce a 421 vessel lymphatic model consisting of 17,706 lymphangions. Several issues which impede large network scale modelling of the lymphatic system are identiﬁed. A simpliﬁed patient-speciﬁc biphasic model of lymphoedema was proposed and used to develop a novel shape-based metric for lymphoedema. A statistically signiﬁcant relationship between the metric and the presence of lymphoedema was found.

This paper deals with a machine-learning model arising from the healthcare sector, namely diabetes progression. The model is reformulated into a regularized optimization problem. The term of the fidelity is the L1 norm and the optimization space of the minimum is constructed by a reproducing kernel Hilbert space (RKSH). The numerical approximation of the model is realized by the Adam method, which shows its success in the numerical experiments (if compared to the stochastic gradient descent (SGD) algorithm).

In this work, we propose a deep prediction diabetes system based on a new version of the support vector machine optimization model. First, we determine three types of patients (noisy, cord, and interior) basing on specific parameters. Second, we equilibrate the clinical data sets by suppressing noisy and cord patients. Third, we determine the support vectors by solving an optimization program with a reasonable size. Our system is performed on the well-known diabetes dataset PIMA. The experimental results show that the proposed method improves the prediction accuracy and the proposed system significantly outperforms all other versions of SVM as well as literature methods of classification.

An important and urgent task is the calculation and choice of selective relay protection, which allows to ensure safe conduct of work in the conditions of mountain quarries. In the work, on the example of mountain quarry, the calculations were carried out for ensuring electrical safety of the consumers in case of emergency modes occurrence due to the appearance of short-circuit currents. At the same time, short-circuit currents in a 6 kV network, maximum current protection and current cut-off were determined, a selectivity map of protection operation was drawn up. Calculations show that with the correct protection settings, the required sensitivity coefficient is ensured in case of the short circuits at any point in the network. The selectivity map of relay protection is drawn up for a normal scheme, in which sectional switches are off at all the voltage levels. The inclusion of these switches does not affect the choice of the protection operation current, and only increases the sensitivity coefficient of the current protection and earth-fault protection. When arranging power supply schemes for the consumers, it is recommended: not to connect more than two consumers of EKG-4.6 or PKTP-400/6 type to the feeder supplying EKG-8; do not connect more than four consumers of EKG-4.6 or PKTP-400/6 type to a separate feeder; 6 kV quarry network and the boiler should be powered from different busbar sections of KRU-2 complete switchgear; it is advisable to have a cable network length of at least 5–6 km from one section of 6 kV KRU-2 busbars, which will increase the reliability of protection against single-phase earth-faults.

Authors:   IPCON RAN, Zaburdayev V.S. , Podobrazhin S.N. ,   STC «Industrial Safety» CJSC
Published: October 2021

Conditions are given concerning the development of methane-bearing coal seams in Russia, the chronology of injuries from explosions and outbreaks of methane-air mixtures at the Russian mines for a quarter of a century of developing coal seams at the nine deposits. The emergency was studied in 174 mine incidents, which occurred mainly at the mines of Kuzbass, Vorkuta coal deposit, Eastern Donbass, Chelyabinsk basin, Primorye and Sakhalin. Emergency objects - excavation areas, preparation faces and mined-out areas of the mines. The sources of ignition of methane-air mixture are drilling and blasting works in the faces, malfunctioning of electrical equipment, frictional sparking, endogenous fires, and smoking in the mines. The most injury-risk for methane are steep and steeply inclined mines. The need in the scientific substantiation of the decisions taken for prevention or reduction of the methane injury-risk at the mines is noted in the article. An important role is assigned to the choice of ways to achieve this goal considering the geological and mining conditions of the development of gas-bearing coal seams. As an example, the conditions, methods, and parameters of mining operations at the excavation areas of four mines are given, where occurred the catastrophic explosions of methane-air and methane-dust-air mixtures. The reasons are gross violations of safety rules during mining operations, incompetence of the mine engineering personnel, design, and control organizations in matters of safety during the underground work at the gas-hazardous mines with an extensive network of workings. This resulted in the death of miners and mine rescuers, the destruction of mine workings, equipment and devices, underground fires. Recommendations are given for reducing the level of methane injury-risk at the methane-rich mines.
On relations in science: the case of the scientific journal editorial board
Authors: Bolshakov D. Yu.
Published: October 2021

This article analyses the connections between members of the editorial board of a scientific journal which are formed based on their reviews of scientific articles. It is shown that the connections can be represented as a graph. The research uses the data for six years of article reviewing in the scientific and technical Journal of "Almaz — Antey" Air and Space Defence Corporation.

The methods of analysis are combinatorics and graph theory, as well as the relevant graph characteristics: adjacency matrix, incidence matrix, reachability matrix, graph fullness and connectivity, nearest neighbours graph and graph spanning tree.

It is shown that cooperation of the reviewers of the Journal helps plot a connected graph with links between any two vertices, i.e. between any reviewers.

The graph is analysed and the methods of its application to calculate the Journal’s scientometric indicators are demonstrated. As the research reveals, a journal that publishes articles in numerous disciplines forms connections between all reviewers and this parameter can be indicative of interchangeability within the scientific fields or, conversely, of a joint work in this scientific field when reviewing manuscripts. Based on the research results, it is possible to search for new reviewers in the areas where competencies are underdeveloped. And by the areas where competencies are strong, we can determine the core competence of the reviewers of a scientific journal, reflecting the main focus of the evaluated scientific research.

The work resulted in the formulated scientometric indicators of the journal, which can be used to search for and involve new reviewers or to represent data on a strong team of reviewers on a specific topic, as well as on a new scientific field just emerging for research.

Tunku Abdul Rahman Park (TARP) is a Marine Protected Area (MPA) and a famous tourist destination in Sabah. The possible long-term negative impacts on the ecology and sustainability of the Park due to the very high number of tourists is of much concern to the Park management authority. This study was conducted to determine the ecological and tourism carrying capacity in three islands in TARP, Manukan, Mamutik and Sapi islands. The Effective Carrying Capacity (ECC) concept is applied in this study, in which the results are expected to provide the Park Authority with data and effective management actions. Calculation of carrying capacity in this study was based on three distinct visiting patterns or seasons: i) Regular season; ii) High season, and iii) Festive season in order to ensure optimal tourists' satisfaction and revenue, while still maintaining ecological sustainability. ECC was calculated after considering the various limitations imposed by physical, climate, ecological, and management capabilities. Land and ocean areas were considered and calculated separately as they occupied different variables. Our findings showed that Manukan island recorded the highest ECC, while Mamutik and Sapi island shared almost similar ECC value. Optimization of Carrying Capacity (CC) in different seasons was also achieved with a few Correction Factor (CF) adjustments. It shows that Festive season recorded the highest ECC, followed by High Season and Regular Season. The ECC obtained was suggested to be implemented to TARP management as to preserve and sustain the ecological value of the Park.
Representações de Brasília em poemas de Nicolas Behr (1977-1980): uma perspectiva metodológica a partir de Hans Robert Jauss | Representations of the city of Brasília in the poetry of Nicolas Behr (1977-1980): a methodological perspective by Hans Robert Jauss

Este artigo discute as representações de Brasília presentes nos poemas de Nicolas Behr, escritos entre 1977 e 1980. O objetivo é apreender, nos poemas dedicados à Capital Federal, parte do ima­ginário social da cidade quase em seu grau zero de saturação histórica. Apresenta-se, para isso, a leitura e a análise orientadas por Hans Robert Jauss que, sob bases da hermenêutica, propõe que se opere sobre os textos literários em três etapas: percepção estética (intelligere), interpretação retros­pectiva (interpretare) e histórica (applicare). Assim, ele também é um experimento metodológico posto a favor da literatura como fonte singular para pensar e representar a cidade.

Eğitim fakültesi 4. sınıf öğrencilerin eğitim fakültelerini ne kadar tanıdıklarını örgüt kültürünün bileşenleri çerçevesinde ortaya koymak amacıyla gerçekleştirilen bu araştırmanın çalışma grubunu Türkiye’de yer alan bir devlet üniversitesinin, Eğitim Fakültesi 141 son sınıf öğrencisi oluşturmuştur. Nitel yöntemin kullanıldığı bu araştırmada desen olarak durum çalışması tercih edilmiştir. Veriler, açık uçlu soruların yer aldığı “Eğitim Fakültemizi ne kadar tanıyoruz?” anketi ile Google formlar aracılığı ile web üzerinden toplanmıştır. Verilerin analizinde, içerik analizi kullanılmıştır. “MAXQDA 2020” paket programı ile kodlanan verilerin analizi yapılmış, veriler yüzde frekans değerleriyle tablolar halinde sunulmuştur. Araştırmadan elde edilen sonuçlara göre, öğretmen adaylarına göre eğitim fakültesi süreç içinde insanı geliştiren, eğitim ve öğretmenliğin temeli olan, aydınlatan insanları amaçlarına ulaştıran bir yer olarak tanımlanmıştır. Eğitim fakültesinin, öğretmen adaylarının beklentilerini genel anlamda karşıladığını ve bunu da hocalar ve eğitim açısından karşılamasıyla ilişkilendirdikleri sonucuna ulaşılmıştır. Bununla birlikte öğretmen adaylarının bulundukları eğitim fakültesinde en çok sızlandıkları durumun fiziki yapı olduğu, eğitim fakültesi dekan ve dekan yardımcılarının kim olduklarını, görev tanımlarını ve odalarının nerede olduğunu bilmediklerini ifade etmişlerdir.
Monitoring extinction: defaunation, technology and the biopolitics of conservation in the Atlantic Forest, Brazil
Authors: Kiggell Thomas
Published: October 2021

Due to habitat fragmentation, Brazil's Atlantic Forest is considered one of the world's most threatened biodiversity hotspots. Much of the biome has become extinct of its largest-bodied mammals,leading some to refer it as a 'half-empty forest.' One of the ways conservation actors are responding to this crisis is by utilizing Global Positioning System(GPS), camera trapping, and remote sensing satellite imagery. Together, these tools enable the collection of data at unprecedent levels. By intensifying wildlife monitoring, it is thought that better-directed actions can be taken to avoid species extinction. Although there is a nascent body of research in political ecology examining the role of these new technologies in conservation,so far there has been little exploration of what this implies for the transformation of the governance of conservation spaces. Bringing together literatures on biopolitics of conservation and conservation technologies, this article reflects on the ways new technologies are changing the biopolitical governance of conservation in the Atlantic Forest. I argue that the increase of information flows, together with the ability to process data through models and algorithms, intensifies the capability of biopolitical governance to justify claims for new protected areas, while changing ecological subjectivities. With the increased use of remote sensing technologies, some ecologists are being distanced from the field, and are consequently having less interactions with rural communities. As pressures on biodiversity increase, this may facilitate advocacy for coercive conservation measures that have adverse impacts on local communities.
Inocuidad, normatividad y calidad como estrategia competitiva: experiencias en el sector porcícola de México y Sonora
Authors: Méndez-Barrón Rosana
Published: October 2021

Objetivo: análisis sobre el rol y peso que los procesos de calidad han tenido en el avance de la industria porcícola. Metodología: una investigación de corte exploratoria dirigida a las empresas integradoras de carne de cerdo en el estado de Sonora. Resultados: documentar la importancia de la calidad y las certificaciones, la cual es más que una práctica empresarial común es un requisito para ser competitivos en los mercados internacionales. Limitaciones: dado que el abordaje es exploratorio, solamente fue posible confirmar la importancia de la normatividad y regulaciones como elemento común en el desempeño de la industria porcícola, pero no fue posible medir/cuantificar su impacto/peso en la competitividad de las empresas. Conclusiones: en el caso de la industria alimentaria, la seguridad es una prioridad, en ese sentido, las empresas que quieren estar a la vanguardia requieren ser capaces, no solo de producir, sino de hacerlo bajo los mejores criterios. En ese sentido, la calidad emerge como un nuevo emblema de competitividad, mismo que ha sido posible verificar a partir de los resultados de la exploración realizada en las empresas porcícolas de Sonora.
Роль геополитических факторов в освоении Восточной Арктики России и адаптации населения
Authors:   Бакланов П. Я., Шведов В. Г.
Published: October 2021

Обострение современной международной обстановки обусловливает актуальность проведения геополитических исследований различного плана и направленности. В этой связи для крупных стран особое значение имеет тематическое изучение состояния своих регионов, а из них в первую очередь – отдалённых приграничных, геополитическая проблематика которых, как правило, имеет ряд специфических характеристик. В России одним из таких регионов является Восточная Арктика – обширное акватерриториальное пространство, которое максимально удалено от центра страны и имеет высокую степень транспортной изоляции от остальной части страны. Восточная Арктика обладает богатым и разнообразным потенциалом стратегического минерального сырья. В её пределах расположено ключевое звено Северного морского пути – Берингов пролив, соединяющий Северный Ледовитый и Тихий океаны. Всё это создаёт благоприятные предпосылки для международного сотрудничества в регионе. Но его развитию препятствует современное обострение российско-американских отношений и ряд нерешённых вопросов по разграничению океанических акваторий. В настоящее время сложилась группа стран АТР, которые проявляют повышенный интерес к данной проблематике. Ряд государств, следуя своим интересам, поддерживают идею США об интернационализации Арктики. Канада, будучи членом НАТО, разделяет позицию России по межгосударственному разделу этого региона. Китай занимает позицию российского стратегического партнёра. В статье проведено исследование по идентификации тех геополитических факторов, которые имеют определяющее значение для Восточной Арктики. Целью данного исследования стало определение воздействия данных факторов на состояние и развитие хозяйственной сферы Восточной Арктики, а также – на адаптацию населения к проживанию и работе в её экстремальных условиях. В результате составлены рекомендации по комплексному военно-гражданскому освоению этого стратегически важного для России региона и по ряду мер, направленных на разрешение его демографических проблем с позиции обеспечения национальной безопасности страны. В работе использованы методы: пространственный анализ, анализ материалов по теме публикации, выборочно-статистический, оценочно-прогнозный.
Ключевые слова: Восточная Арктика, геополитические факторы, минерально-сырьевой потенциал, судоходные трассы, наземные транспортные пути, хозяйственное освоение, межгосударственные отношения, оборонный потенциал, акваториальное разграничение, стратегическое партнёрство, адаптация населения.
