Authors: Takkar Brijesh , Sahoo Niroj Kumar , Tyagi Mudit , Dave Vivek Pravin
Published: May 2022

Introduction: Chorioretinitis sclopetaria (CS) is a rare consequence of ocular injury. Its association with open globe injury (OGI) and retinal detachment (RD) is controversial. This study evaluates patterns of chorioretinitis sclopetaria and its association with open globe injury and retinal detachment.
Case:  This is an electronic review of records of a tertiary eye care institute of south India with descriptive analysis of six cases. Cases where fundus findings of chorioretinitis sclopetaria were available were included. Information regarding mode of injury, visual outcomes, follow up and causes of poor visual outcomes were obtained. Presence of open globe injury, retinal detachment, vitreous hemorrhage (VH) and orbital foreign body (FB) was also noted. Ultrasound scans of the eyeball were reviewed for presence of signs of chorioretinitis sclopetaria. 
Observations: All the injured patients were male (age range 23-52 years). Bullet and blast injuries were the modes of injury. The duration since injury to the last follow up ranged from 0.25 to 12 years. The final visual acuity was <20/200 in 3/6 cases. Open globe injury and retinal detachment was noted in one case each, while 3/5 cases had orbital foreign body. Extensive facial and neuro-surgery were required in 2/6 cases. Sonography showed signs of chorioretinitis sclopetaria in 2/3 cases where scans were available for review.      
Conclusions: Though manifestations of chorioretinitis sclopetaria evolve with time with visual improvement, final visual acuity is generally poor. Cases of chorioretinitis sclopetaria may have accompanying retinal detachment or open globe injury. Sonography should be evaluated with a high degree of suspicion for chorioretinitis sclopetaria in typical cases.

Published: May 2022

Introduction: Major cause of irreversible blindness is glaucoma which is increasing as a significant global health problem. Knowledge of glaucoma burden and its clinical characteristics in this region is essential.
Materials and methods: This was a cross-sectional hospital -based study conducted at Glaucoma unit in CHEERS Hospital, Bhaktapur from August 2015 to July 2019. Patients’ demographic profile, along with comprehensive eye examination findings were reviewed from the records. Data analysis was done with IBM SPSS version 24 and was presented in mean (±SD), frequency and proportions and a chi- square test was applied. P value < 0.05 was considered statistically significant. 
Results: Total of 310 glaucoma cases were included in this study. The mean age presentation was 61.89±14.4 years, and the majority of patients (52.9%) were in the age group 60-79 years. Most patients had primary open angle glaucoma (171, 55.2%) followed by primary angle closure glaucoma (92, 29.7%).
Conclusion: Primary open angle glaucoma is the most common form of glaucoma. The proportion of glaucoma increased with increasing age (> 40 years). Provision of screening programs targeting persons with risk factors and opportunistic eye examinations would be beneficial in detection of glaucoma.
Ocular Manifestations Leading to a Diagnosis of Joubert Syndrome Related Disorder
Authors: Jain Divya , Ravishankar Venkateshwar
Published: May 2022

Introduction: Joubert syndrome is an inherited disorder of rare occurrence usually presenting as developmental delay, hypotonia, hyperpnea and ataxia. The diagnosis is confirmed by characteristic findings in neuroimaging. Involvement of ocular, renal and hepatic systems can be present. Joubert syndrome presenting first to an ophthalmologist is very uncommon.
Case: A twenty-one-year female, with history of delayed milestones, infantile hemiplegia with hearing and visual impairment was referred for visual assessment. On systemic examination, ataxic gait was present. CT head showed hypoplasia of postero-inferior portion of vermis with communication between 4th ventricle and cisterna magna with variable degree of cerebellar dysgenesis. The neurological, ophthalmological and radiological findings of this patient were consistent with Joubert syndrome related disorder.
Conclusion: We hereby report a case of Joubert syndrome related disorder with ocular involvement which after correlation with neurological findings and neuroimaging led us to the diagnosis of this rare disorder. The renal and hepatic functions in these patients need to be monitored.

Authors: Giri Puspa , Bajracharya Leena , Ranabhat Sudha
Published: May 2022

Introduction: Macular corneal dystrophy (MCD) is a rare autosomal recessive stromal dystrophy. The prevalence of inherited diseases varies in different communities. It is not commonly observed in Nepal.
Case: A 14-year male presented with bilateral gradual and painless blurred vision with photophobia of three years duration. Cornea of both eyes showed focal grayish opacities in anterior and mid stroma with intervening stromal haze. There was no history of consanguinity in the family. Anterior segment ocular coherence tomography showed thinning of cornea and deposits in corneal stroma. Macular corneal dystrophy was the clinical diagnosis and the patient underwent deep anterior lamellar keratoplasty in the right eye. Histopathological examination and histochemical staining with Alcian Blue supported the diagnosis. 
Conclusion: Significant improvement in vision was observed in the operated eye. MCD may be present in communities without evidence of consanguinity. It can cause visual impairment at an early age. Timely intervention improves vision and quality of life.
Burden and Risk Factors of Diabetic Retinopathy Among Diabetic Patients Attending a Multispecialty Tertiary Eye Hospital in Nepal
Authors: Shrestha Arjun , Suwal Rinkal , Shrestha Rajan , Khadka Deepak
Published: May 2022

Introduction: As the number of people with diabetes mellitus is increasing because of urbanization and change in dietary habits and sedentary lifestyle, the number of diabetic retinopathy is also expected to increase in future. [1] [sa2] We aimed to find out the prevalence of diabetic retinopathy and associated risk factors among diabetic patients in the tertiary eye hospital.
Materials and methods:  This is the observational cross-sectional study enrolling 420 diabetic patients visiting the multispecialty tertiary eye hospital between March 2020 and February 2021. Anthropometry measurement, laboratory risk profiles and blood pressure were recorded
Results: The prevalence of any diabetic retinopathy, proliferative diabetic retinopathy, and diabetic macular edema were 30.96 %, 6.19 %, and 5.95 % respectively. The duration of DM (p=0.001), hypertension (p=0.04), high SBP (p=0.023), abdominal obesity (p=0.015), high LDL(p=0.011) cholesterol, low HDL cholesterol(p=0.012), and creatinine (p=0.001) were associated with DR in our study. 
Conclusion: A holistic approach should target to control the modifiable risk factors like blood sugar, blood pressure, lipid profile, kidney function, and obesity to prevent DR. Anthropometric assessment of waist to height and waist circumference should be included in the holistic health promotion strategy in Nepal as BMI may not be risk factors for DR in Nepalese people.
An Unusual Presentation of Corneal Intraepithelial Neoplasia: A Case Report
Authors: Bajracharya Leena , Sapkota Jyoti
Published: May 2022

Introduction: Corneal squamous neoplasia is less common than that of conjunctiva and can cause diagnostic confusion.
Case: A 40-year-old male presented with gradual onset blurring of vision in left eye for 8 weeks. He had received treatment for dry eyes, then for herpetic dendritic keratitis, but without improvement. On slit-lamp examination with diffuse light, apparently the cornea looked clear with some dilated conjunctival vessels nasally. But in the retro-illumination, on the corneal surface, there was a translucent inverted “V” shaped lesion with irregular fimbricated margin. He underwent excisional biopsy of the corneal lesion and the adjacent conjunctiva.  Cryotherapy of the conjunctival margin and the adjoining limbus was done. Corneal and conjunctival specimens reported intraepithelial neoplasia grade II and I respectively.There had not been any recurrence till 4 year post-operatively.
Conclusion: Corneal examination by retro-illumination aids to diagnose and demarcate corneal intraepithelial neoplasia clinically. Timely management results in good prognosis.
Glosa do Wyroku Trybunału Konstytucyjnego Republiki Kolumbii z dnia 26 kwietnia 2017 r., sygn. akt C-246/17
Authors: Pogłódek Andrzej , Stachowicz Anna
Published: May 2022

This paper studies the case law of the Constitutional Court of the Republic of Colombia of 26 April 2017 (Case C-246/17) which interpret the capacity of the minor to give informed consent to aesthetic medicine and plastic surgery treatments, as well as participation of such person in campaigns promoting this type of treatments. In this case, the Court first decided that the ban on aesthetic medicine and plastic surgery procedures for minors should not be applied to adolescents over 14 years of age who, due to their level of development, are able to participate together with persons having parental authority in the decision-making about the risks involved in such procedures and are able to consent to the procedure in an informed and qualified manner. The Constitutional Court also finds that the prohibition on participating in campaigns promoting cosmetic medicine clinics and the treatments carried out there, which applies to persons aged between 15 and 18, is a proportionate and effective restriction. In this way, the legislator achieves constitutionally legitimate objectives, i.e. discouraging treatments that may expose the health of a minor to unnecessary risks and reducing gender stereotypes regarding a certain canon of beauty. In assessing this ruling, the article examines the concepts of: “free development of personality”, “right to privacy”, “informed consent to medical treatment” of minors, as well as “legal moralism” and “paternalist measures”. To this end, a dogmatic method was used by reviewing the case law of the Constitutional Court of the Republic of Colombia, and the results obtained were presented through a descriptive method. In the conclusions, attention is drawn to the consistent doctrine existing in the Court’s jurisprudence relating to the concepts.
Psychology and the Paranormal by David F. Marks
Authors: Kennedy James E
Published: May 2022

David Marks’ previous book about the paranormal (Marks, 2000) and other earlier writings established his reputation as a firm skeptic. He wrote the current book in order to learn about new developments in paranormal research during the past 20 years. 

The overall conclusion in this book is that Marks now believes that spontaneous paranormal phenomena may occur, but psi is a spontaneous process that cannot be controlled and demonstrated in laboratory experiments. His belief that instances of spontaneous psi may occur is based largely on a personal experience of synchronicity that had layers of meaning for him. The experience is described and evaluated in chapter four. He rates the probability as 75% that the experience had a paranormal component.
Scrutinizing the Relationship between Subjective Anomalous Experiences and Psychotic Symptoms
Authors: Escolà-Gascón Álex , Rusiñol Estragues Jordi
Published: May 2022

Abstract

This research was exploratory and its main objective was to analyze whether anomalous experiences related to parapsychology had similar statistical behavior to psychotic-like experiences (e.g., hallucinations). If psi phenomena have a different ontology from psychotic-like experiences, then they should have a different statistical representation and measurement. In this hypothetical scenario, there would be empirical-statistical grounds for discriminating between psychotic perceptual distortions and anomalous experiences without clinical origin. Different clinical variables common in psychotic disorders were measured in 562 participants. Psychotic-like experiences (as hallucinations) and anomalous experiences (as experiences outside the framework of psychosis) were also quantified. Several forward stepwise multiple regression models and techniques based on Exploratory Factor Analysis were used. The EFA extracted 2 factors; the first grouped the variables that measured anomalous phenomena from the continuum of psychosis model and the second gathered the variables that measured them as anomalous perceptions without scientific explanation. Both EFAs explained more than 70% of the variance. Only 3 clinical variables were necessary to predict 58.8% of psychotic –like experiences assessed from the psychopathological model. Up to 6 indicators were necessary to predict 54.5% of the unexplained anomalous experiences. There are empirical-statistical indicators in the used sample that enable the differentiation of the anomalous phenomena in the two prominent models. The variables that characterize the psychotic phenotype predict more successfully psychotic-like experiences than anomalous experiences. It is discussed whether the factors extracted in the EFA represent psychological constructs with different etiologies or if both dimensions come from the same underlying construct.

Keywords: Anomalous Experiences; Schizotypy; Psychotic-like experiences; Paranormal Beliefs; Psi Phenomena.
The Real Anthony Fauci. Bill Gates, Big Pharma, and the Global War on Democracy and Public Health by Robert F. Kennedy
Authors: Walach Harald
Published: May 2022

Let me start this review with my declaration of conflict of interest, intellectually of course: I have done some background research and reading on mercury toxicity (Mutter et al., 2010; Mutter et al., 2005), from thimerosal (ethylmercury, a preservative that used to be in vaccines until about 10 years ago) and amalgams. This is an area, where Robert F. Kennedy has been politically quite active with his Children’s Health Defence foundation. I am therefore favorably inclined to Kennedy’s activities, although I am certainly not an anti-vaxxer. My personal stance here is: some vaccines are useful and safe, some are not, and likely it is best to take them in separate steps, as we did with our children. I have also done primary research on Covid-19 right from the beginning (Walach & Hockertz, 2020a, 2020b) – modeling (Klement & Walach, 2021), conducting surveys (Walach et al., 2022; Walach, Ruof, et al., 2021), looking at data, blogging in Germany – conducting two highly visible and highly controversial studies (Walach, Klement, et al., 2021a; Walach, Weikl, et al., 2021), which have both been retracted within a week, one of them republished (Walach, Klement, et al., 2021b), the other still under a new review. I was critical of the official Covid-19 narrative as soon as I discovered huge discrepancies between original data and reports in the media, as well as analyses of media-prone scientists that were ostensibly wrong; we have succeeded in publishing a critique of one such dangerously wrong analysis (Dehning et al., 2020) about 2 years after the original one was out, following two rejections and long rounds of reviewing (Kuhbandner et al., 2022). So, I have learned a lot of lessons there. I initially thought, we are dealing with a mistake, due to a novel threat and confusion in how to react. The more I saw and experienced myself, the more I lost that stance of innocence and thought that, perhaps there was an initial accident or problem, but surely very soon some people used it to ride their own hobby horses. Collateral utility, as I call it. That is the reason, why I embarked on my own social-science study: interviews with activists in Germany and elsewhere, who wrote articles, blogged, were visible in the public. I have conducted 13 interviews so far, and the tacit and express knowledge from those interviews is of course also feeding my viewpoint.
Response to Jim Tucker
Authors: Sudduth Michael
Published: May 2022

Let me begin by thanking Jim Tucker for offering his thoughts on my JSE paper on the James Leininger case (Sudduth 2021). I appreciate his clarifying his interpretation of several of the facts in the case, as well as his providing further context to some of them. I also appreciate his acknowledgement of Bruce Leininger’s authorship of the 2003 chronology which I uncovered in my investigation and made use of in my paper. That’s all helpful. For the rest, I wish I could say what St. Augustine said to Evodius when responding to the latter’s criticisms – “you have knocked vigorously.” Alas, I cannot say this about Tucker’s response.

My paper developed a number of different concerns about the evidential value of the James Leininger case (hereafter, JL case). The paper was lengthy and the scope of the material I presented was broad, often involving considerable detail regarding different aspects of the case. I realize this can make writing a concise and salient response a daunting task. To effectively navigate the landscape, therefore, it’s crucial to properly understand the structure and content of my arguments, as well as how I intend to leverage various facts in the service of specific lines of argument. One must not miss the forest (the argument) for the trees (particular facts). Or, in the words of St. Augustine, one must knock vigorously. Tucker has not.

Authors: O’Hoski Sachi , Ellerton Lauren , Selzler Anne-Marie , Goldstein Roger , Brooks Dina
Published: May 2022

Purpose: We aimed to elicit patients’ views of research priorities related to pulmonary rehabilitation (PR). Method:We used a modified nominal group technique in which participants with chronic lung conditions who had completed PR attended one of five meetings during which they generated ideas, discussed them with the group, and prioritized their top three topics. Afterward, they completed member checking and satisfaction questionnaires. Results:Fourteen participants (mean age 71 years) prioritized 25 topics, which included music as a motivator, education about the reason for various assessments and exercises, and ongoing patient assessment and follow-up. Most participants “totally agreed” that the summarized topics matched what they thought was important in PR research (75%) and that the meeting was a positive experience (100%). Participants indicated that the findings of this study accurately reflected their priorities. Conclusions:Individuals who have completed PR may have questions about programme components including assessment, treatment, and strategies for promoting motivation. To inform future research projects and identify knowledge translation needs, we will distribute a questionnaire to a larger sample of former PR patients to further prioritize the 25 topics identified in the meetings.

The article presents studies of the use of plasticizing additives in combination with fine aggregate (microsilica) and CaOH quicklime for the production of foam concrete. The research will determine the effect of plasticizing additives and active fillers on the properties of foam concrete during their production. The main issue in the production of foam concrete is the time of setting, as their increase leads to shrinkage of foam concrete mixture and as a consequence of the uneven structure of the material. Therefore, the use of plasticizer additives in the production of foam concrete is not recommended. Plasticizer, as a surface-active substance, increases the setting time of the cement binder. However, examining the features of micro silica in combination with caustic lime and plasticizer was found to reduce the time setting. Laboratory studies have shown that the use of these components will produce foam concrete with the projected density, with a uniformly distributed pore structure, high strength, and frost resistance. According to the results of the study, the influence of the number of additives components on the qualitative characteristics of foam concrete was determined, and the optimal composition of the components, plasticizer additives, micro silica, and caustic lime was selected.

In the electrometallurgy of manganese alloys, viscosity has an important effect on the production indicators from the physicochemical properties of slag. During the smelting of manganese alloys, the main amount of heat spent on reduction reactions is released due to the current passing through the liquid slag phase, since the resistance of the latter, depending on the composition, affects the completeness of the reduction of manganese from melts. In the case of refined ferromanganese by the silicothermic method, the vast majority of silicon of silicomanganese is refined with higher manganese oxides or it is burned out due to oxygen in the air. The paper presents the results of thermophysical properties of slags representing the FeO - MnO - CaO - Al2O3 - SiO2 system. Laboratory experiments were carried out on synthetic slags by varying the slag basicity CaO / SiО2 = 1.5 - 1.9 and the concentration of Al2O3 = 5 - 15%. As a result, graphs of the dependence of these properties on temperature values are constructed, the activation energies of the viscous flow are calculated and the phase compositions of the experimental slags are determined using a mathematical model of the diagram of the FeO - MnO - CaO - Al2O3 - SiO2 system. Thus, an increase in the concentration of aluminum oxide against its usual level, changing the basicity of the slag, significantly affected the physicochemical properties of the slag and thereby contributes to the adjustment of the parameters of the electric melting process. At the same time, it is advisable to study the interaction of some Physical chemical properties of slags on the melting conditions of manganese ferroalloys in relation to the composition of slags.

Metals are important in many modern industries. Due to the depletion of their natural resource base, it is necessary to adapt, which means developing new and optimizing existing methods of extraction of valuable components from ore materials. Only comprehensive processing of copper metallurgical slags will solve the problem of resource recovery and the creation of low-waste technology, which has great economic, environmental, and social importance. Hydrometallurgical technologies take into account the specific conditions of the system and the physical and chemical properties of metals when developing and selecting the method of extraction. This article provides a review of the current state and prospects of development technologies used for base metal extraction by leaching with the use of inorganic acids and environmentally safe reagents, the methods are conditionally divided into two groups. The listed studies have made a significant contribution to solving the problem of processing metallurgical slags, however, none of the technologies has gone beyond the scope of laboratory and semi-industrial tests. Noted a tendency to reduce the concentrations of leaching agents by certain pre-treatment of raw material, as well as the transition to ubiquitously use "green technologies": such as bioleaching and organic acid leaching. Directions are suggested to solve the problem of rational use of raw materials and increase the sustainability of the future material cycle.

It is shown that the complexity of Kazakhstan's oils requires specific ways to protect oil pipelines from damage caused by metal corrosion. Even the presence of only paraffin in oil can cause sedimentation effects in the volume of liquid (Dorn effect). And the complexity in the molecular composition of oil causes electrophoretic impacts that lead to increased corrosion rate. All this should be considered when developing corrosion protection. The physical and mathematical analysis of possible mechanisms of electrophoretic mobility of components with the participation of liquid systems was carried out. In such a system with ions content, the macroscopic object will move as a charged particle having the same charge sign as the skeleton. The triboelectric effects on the metal/organic liquids (oil, fuel oil, etc.) boundary have been analyzed to determine their influence on the corrosion of pipeline metals. There are many methods used for temperature-strength control of reinforced concrete structures globally. Their majority is associated with the significant challenges of being time-consuming, costly, and prone to errors. Therefore, this study investigated the potential applicability of the surface-strength approach of specimens using non-destructive testing methods to derive temperature-strength relationships as an alternative approach to the currently widely used methods.

The work is devoted to the problem of an increase in the proportion of scrap metal in castings smelted and produced from wear-resistant chromium cast irons. Castings obtained with more than 60% of armor scrap and cracked during solidification and subsequent heat treatment were selected as research objects. Castings of similar mill armor after operation characterized with different wear resistance were selected to compare the characteristics of the structure and properties. The composition, structure, amount of non-metallic inclusion and porosity of samples cut from identical places of castings were studied with the help of the methods of optical and scanning microscopy, metallographic analysis, X-ray fluorescence analysis, and measurement of Vickers hardness. The characteristic localization of non-metallic inclusions of various types in the structure of cast iron samples was considered. An increase in the proportion of non-metallic inclusions in cast irons obtained using a high proportion of scrap was found, and it was shown that non-metallic oxide inclusions with a loose structure had the most negative effect. Along with porosity and primary crystals of carbide (CrFe)3Ctheydo not prevent the propagation of cracks caused by internal stresses arising during crystallization and subsequent polymorphic transformations in castings.

The main problem of cement production is to reduce energy consumption and reduce the amount of greenhouse gases CO2 emitted into the atmosphere. The prerequisite for solving the problem is: the use of man-made waste and unconventional raw materials in the composition of the charge and the reduction of limestone content from 85% to 70-75% as a source of CO2 gas. The article presents the results of the studied technogenic waste and the suitability of non-traditional raw materials such as tefritobazalt, coal mining waste, and lead slag. The chemical and mineralogical composition of the materials and their suitability for obtaining environmentally friendly clinker have been established. The possibility of obtaining cement clinker using low-energy resource-saving technologies is shown. Clinker formation processes in the developed mixtures are completed at a temperature of 1350 °C, which, with the coal contained in the waste, will reduce the consumption of fuel injectors and reduce CO2 emissions into the atmosphere. In the developed low-energy mixtures, the specific consumption of raw materials for obtaining 1 ton of clinker is reduced to 1516-1525 kg, which is significantly lower than in traditional raw mixtures. Alite crystals are large, reaching 100-140 microns. The content of clinker minerals is C3S-57.88%, C2S-18.82%, C3A-6.46% and C4AF-11.61%. Disposal of large-tonnage waste will reduce environmental pollution and improve the environmental situation in the region.

“Revolutionary” technologies or large technological systems are often deemed controversial, risky, or ambivalent. Diverging interpretations clash when technological objects, such as rockets, airplanes, or nuclear reactors, are exhibited in museums or at heritage sites, with profound implications for underlying concepts of historical education. This special issue explores the argument that histories of technology have often upheld a traditional view of modern linear progress but became the focus of controversies when the social, political, and cultural conditions of perceiving and remembering these objects changed. At former “places of progress,” visitors and exhibition makers are confronted with the remains of the Industrial Revolution, colonialism, two World Wars, the Cold War, the Age of Coal, the Space Age, the Atomic Age and the Digital Age. Exhibitions and displays have been used to explain, teach, or make sense of the advents, successes, and failures of high-tech projects. Understanding technological artifacts and corresponding sites such as Chernobyl, Peenemünde, and Hiroshima as well as structures such as factories or bunkers as sites of memory (lieux de mémoire, a term coined by Pierre Nora) shifts our attention to processes of remembering modern technologies and the cases in which established narratives of progress have been supported or challenged. Questions about the ethics of technology use often seem to subvert stories of the “heroes of invention,” leaving visitors with the impression of technological ambivalence. Attempts to teach and learn about history and technology via objects and sites have been complicated, politicized, and contested.
Ambiguous Narratives of World War Technologies in Contemporary Military History Museums
Authors: Jaeger Stephan
Published: May 2022

This article provides an analysis of how military history museums in Germany, Britain, Belgium, Poland, and the United States exhibit and contextualize weapon technologies that were developed in the two world wars. The article focuses on technologies (gas warfare, the atomic bomb, tanks, and the V2 long-range rocket) that are directly connected to military success and innovation but also relate to dehumanization and destruction. By employing the analytical concepts of experientiality and of antagonistic, cosmopolitan, and entangled memory, this article demonstrates how museums can create open or closed narratives, steer the visitor toward particular interpretations, enhance or deconstruct the authentic aura of technological artifacts, and stage the symbolic potential of technologies. In addition, it shows how museums can educate visitors and allow them to experience the ambiguities, controversies, and complexities of these technologies.
All-Male Warrior Dances and Men's Groups Coping with the Decline of Manhood and Immigration in the Sakha Republic (Yakutia)
Authors: Tarasova Zoia
Published: May 2022

In the late 1990s and early 2000s, much of social research on contemporary Russia focused on transformations of gender relations brought about by the closure of many state enterprises. In particular, scholars posited that men were experiencing severe insecurity about their gender identity, which they termed a “post-Soviet masculinity crisis.” However, little research has since been carried out to catch up with these findings. How have men's experiences of gender insecurity developed? How have they responded? This article addresses these questions drawing on newly active Sakha (Yakut) men's groups and shows how they are also arising and forming their consciousness in reaction to the immigration of male Muslim workers from Central Asia.
Ivory Carving in Yakutia

Within Russia, the major centers of bone carving art are the village of Kholmogory in the Arkhangelsk region, the town of Tobolsk in the Tyumen region (which was considered the center of Siberia in the seventeenth century), Chukotka, and the Republic of Sakha (Yakutia). Geographically, they are connected by their proximity to the northern seas, which explains the main materials used by carvers: walrus tusk and sperm whale tooth. The exception is Sakha (Yakutia), the ancient motherland of mammoths. This article discusses the origin and history of the development of Sakha mammoth tusk carving, the role of ethnocultural contacts at different stages of its development, and the preservation of its authenticity.

A hanseníase é uma doença infectocontagiosa, crônica, de evolução lenta e que se manifesta principalmente através de sinais e sintomas dermatológicos e neurológicos, tais como lesões na pele e nos nervos periféricos (WHO, 2018). Sabe-se que é extenso o número de pessoas que convivem com a doença e não procuram atendimento especializado por não possuir sinais e sintomas aparentes, dificultando o diagnóstico. Logo, o indivíduo pode diminuir ou perder a força muscular e a sensibilidade, agravando o índice de incapacidades e deformidades, com consequente exclusão social (MAYMONE et al., 2020; PALIT et al., 2020; BRASIL, 2017). Apesar de a hanseníase ter sido declarada pela Organização Mundial de Saúde (OMS), como um problema global de saúde “eliminado”, em torno de 200.000 mil novos casos por ano foram notificados no mundo na última década (MAYMONE et al., 2020). O Brasil não conseguiu cumprir o objetivo de desenvolvimento do milênio estabelecido pela Organização das Nações Unidas (ONU) de eliminar a hanseníase até o fim de 2015 (ou seja, registrar um caso a cada 10 mil habitantes no máximo) (ALBANO et al., 2016). O Brasil foi responsável por 92,3% dos casos de hanseníase nas américas, com coeficientes de detecção de hanseníase heterogêneos, e hiperendêmicos em muitos estados das regiões Norte, tendo o estado do Tocantins alta incidência da doença e seus municípios, em sua maioria, hiperendêmicos (MONTEIRO et al, 2020; 2015). O interesse por essa temática surgiu a partir de leituras que evidenciam que, mesmo atualmente, ainda existe um enorme preconceito por parte da sociedade com relação à hanseníase, sobretudo, devido à falta de conhecimento de inúmeros fatores sobre a doença, em especial sobre a questão do contágio. Entende-se que um dos desafios encontrados pelos pacientes em tratamento da hanseníase ainda é a dificuldade de aceitação e inclusão social. Sendo assim, há um interesse em conhecer como os pacientes acometidos pela hanseníase enfrentam a realidade da doença, bem como se apresentam outras dificuldades relacionadas a doença e os tipos de preconceito vivenciados pelos portadores. O estudo torna-se relevante uma vez que podem ser apresentados resultados que poderão trazer esclarecimentos sobre a doença, questões relacionadas ao tratamento e a forma de contágio. A falta de informação por parte da população a respeito da doença, contribui para a predominância do estigma e preconceito em torno da hanseníase, os quais prejudicam e dificultam a vivência e inserção social destes pacientes. Portanto, o presente estudo busca analisar as percepções atuais sobre a hanseníase. Tendo como foco principal conhecer os estigmas e preconceitos vivenciados pelos portadores da doença no município de Palmas, estado de Tocantins, Brasil, a fim de contribuir para que haja um maior esclarecimento e conscientização da população.
UM ESTUDO DE REDES NEURAIS CONVOLUCIONAIS E SUA APLICAÇÃO NA CLASSIFICAÇÃO DE FITAS DE PH UTILIZANDO O APLICATIVO PHREADER

Potencial hidrogeniônico (pH), de acordo com GAMA e ALONSO (2007), é definido como uma escala logarítmica de 0 a 14, utilizada para medir a concentração de íons de hidrogênio em quaisquer substâncias. Os valores dessa escala são utilizados para constatar a acidez das substâncias analisadas. Conforme TERCI e ROSSI (2002), indicadores de pH são substâncias que alteram sua cor em função do valor de pH. Um indicador muito utilizado em instituições de ensino e em laboratórios químicos é a fita universal indicadora de pH. Seu uso em escala se deve ao baixo custo, em comparação com outros indicadores, e fácil manuseio. No entanto, existem certas desvantagens na utilização da fita universal. Um exemplo é a subjetividade na interpretação das cores obtidas a olho nu, limitando a precisão dos resultados obtidos. Diante do exposto, MOTA e OLIVEIRA (2020) desenvolveram um aplicativo, intitulado pHreader, em parceria com o Instituto Federal de Mato Grosso do Sul. A aplicação possui o intuito de auxiliar no processo de determinação do valor de pH, a partir de fotografias de fitas indicadoras. O aplicativo faz uso de uma rede neural artificial (RNA) treinada para o processo de classificação de imagens. Isso posto, o objetivo do presente trabalho é comparar a precisão obtida pela RNA presente no aplicativo em relação a obtida em uma RNA específica no processo de classificação de imagens. Essa comparação tem o intuito de constatar se o uso de uma RNA alternativa pode alcançar uma precisão superior à atual, a partir de um conjunto de treinamento escasso. Isso se deve ao fato da RNA da aplicação possuir um percentual de acerto de 87,5% quando treinada com um conjunto de 30 fotografias por valor de pH.

A escravidão no Brasil durou três séculos, esse período foi marcado por diversas lutas e movimentos, no qual se pôde registrar a criação de várias manifestações de resistência. Os grupos denominados “quilombos” (em angolando “kilombo” significa fortaleza ou povoação) eram comunidades escondidas que abrigavam escravos africanos e nativos fugitivos. Dentro destes centros, os moradores se mantinham em sociedades organizadas, com seus próprios sistemas de governo (geralmente semelhantes aos tipos de governos desenvolvidos em tribos africanas) em que haviam a divisão de tarefas, treinamentos de guerreiros para defender o território e multirões para libertar escravizados nos engenhos. A presença dessas comunidades foi muito importante para a história negra e brasileira, perdurando até os dias atuais. Por muito tempo, elas foram invalidadas, invadidas e agredidas, e ainda hoje tem seus aspectos culturais apagados e a sua luta depredada. Porém, esses fatos não foram e não são impedimentos na resistência dos quilombolas, contanto que muitas comunidades ainda persistem fortes em várias regiões do Brasil. Os descendentes quilombos eram chamados de “remanescentes de quilombo”, porém no século XX, a partir da Constituição de 1988, a palavra “quilombo” passa a ser ressignificada e apresenta três características: a resistência cultural, resistência política e a resistência negra (SEPPIR, 2004). Visando apresentar a história e a resistência dos Quilombos, a proposta deste trabalho é realizar o mapeamento das vinte e duas comunidades quilombolas certificadas pela Fundação Cultural Palmares (FCP), no estado de Mato Grosso do Sul. Após a realização do mapeamento, os dados obtidos foram inseridos no mapa interativo do site. Também foram disponibilizadas páginas para cada comunidade quilombola que, além da localização do território, conta e contará com informações, vídeos e imagens sobre a criação, organização, manifestações culturais, religiosas e o processo de resistência dessas comunidades. As vinte e duas comunidades quilombolas estão localizadas em quinze municípios do estado de Mato Grosso do Sul, sendo que quatro desses municípios possuem campus do IFMS: Aquidauana, Campo Grande, Corumbá e Dourados.
