Rediscovery of Primula brachystoma (Primulaceae), a rare species endemic to Gaoligong Mountain of Chinese-Burma frontier
Authors: Jiang Xiao-Qi , Zhang Na , Wu Zhi-Kun
Published: May 2023

The rare Primula brachystoma W.W.Sm. is an endemic species confined to Gaoligong mountain of Chinese-Burma frontier, which has been rediscovered from the same region after nearly 100 years. In total, 11 specimens from Gaoligong Mountain have been found in the herbaria worldwide, since its first collection in 1920 by Farrer, Reginald John. Previously, this species was described as homostylous but our finding shows the species also exhibited heterostyly. A complete description of the species, the distribution, morphological comparison and identification key from closely related species are provided here. An assessment of its conservation status suggests that the species is ‘Endangered’ (EN).

Être jeune à Mayotte, un devenir adulte sous contrainte ?
Authors: Temporal Franck
Published: May 2023

Cet article compare les âges au passage des principaux événements d’entrée dans la vie adulte des jeunes natifs de Mayotte et des jeunes nés aux Comores, à partir d’une exploitation quantitative des données de l’enquête de l’INED et de l’INSEE Migrations, famille et vieillissement (MFV) menée en 2015-2016. La sortie du système scolaire, le départ de chez les parents, la première union ainsi que le fait d’avoir un premier enfant sont toujours plus précoces chez les jeunes originaires des Comores et les écarts sont toujours plus marqués chez les jeunes femmes que chez les jeunes hommes résidant à Mayotte. Ces différences de calendrier semblent s’expliquer avant tout par des déterminants socioéconomiques.
Les projets de mobilité des jeunes réunionnais·es : une affaire de famille
Authors: Haddad Marine
Published: May 2023

Cet article s’inscrit dans les recherches liant mobilités sociale et spatiale, en interrogeant les mécanismes et représentations associés aux trajectoires résidentielles et migratoires des jeunes réunionnais·es. Il prête une attention particulière à la famille comme site de coproduction de ces trajectoires, faisant intervenir des logiques de classe, de genre et d’aînesse. Croisant l’enquête Migrations, famille et vieillissement menée par l’INED en 2010 et un corpus de 18 entretiens, il retrace les parcours de 6 jeunes des classes moyennes supérieures, les situant dans leurs biographies familiales et dans l’espace de la jeunesse réunionnaise. Il montre comment les choix de partir ou rester s’inscrivent, d’une part, dans des processus collectifs de décision fortement ancrés dans l’espace de la famille et, d’autre part, dans une renégociation des rôles familiaux, qui fait partie des canaux de transition vers l’âge adulte.

Objectives: To compare overall survival (OS), recurrence free survival (RFS), and cancer-specific survival (CSS) in the long-term follow-up of T1 and T2 clear-cell-Renal Cell Carcinoma (ccRCC) and papillary Renal Cell Carcinoma (pRCC) patients, as well as to determine the risk factors for recurrence and overall mortality. Material and method: Data of patients with kidney tumors obtained from the Urologic Cancer Database - Kidney (UroCaD-K) of Turkish Urooncology Association (TUOA) were evaluated retrospectively. Out of them, patients who had pathological T1-T2 ccRCC and pRCC were included in the study. According to the two histological subtype, recurrence and mortality status, RFS, OS and CSS data were analyzed. Results: RFS, OS and CSS of pRCC and ccRCC were found to be similar. Radiological local invasion was shown to be a risk factor for recurrence in pRCC, and age was the only independent factor affecting overall mortality. Conclusions: There were no differences in survivals (RFS, OS and CSS) of patients with localized papillary and clear cell RCC. While age was the only factor affecting overall mortality, radiological local invasion was a risk factor for recurrence in papillary RCC.

Published: May 2023

The presence of anaemia in patients with chronic kidney disease (CKD) is associated with decreased quality of life, along with increased morbidity, mortality, and hospitalization rates. This, in turn, affects healthcare costs and the utilization of medical resources. The mechanisms involved in anaemia of CKD are diverse and complex. They include reduced production of endogenous erythropoietin (EPO), absolute and/or functional iron deficiency (due to inflammation leading to elevated levels of hepcidin), the diminished response of the bone marrow to EPO due to uraemic toxins, the shortened lifespan of red blood cells (RBC), and deficiencies in vitamin B12 or folic acid.

JOURNAL/nrgr/04.03/01300535-202403000-00042/inline-graphic1/v/2023-09-27T141015Z/r/image-tiff

Epilepsy frequently leads to cognitive dysfunction and approaches to treatment remain limited. Although regular exercise effectively improves learning and memory functions across multiple neurological diseases, its application in patients with epilepsy remains controversial. Here, we adopted a 14-day treadmill-exercise paradigm in a pilocarpine injection-induced mouse model of epilepsy. Cognitive assays confirmed the improvement of object and spatial memory after endurance training, and electrophysiological studies revealed the maintenance of hippocampal plasticity as a result of physical exercise. Investigations of the mechanisms underlying this effect revealed that exercise protected parvalbumin interneurons, probably via the suppression of neuroinflammation and improved integrity of blood-brain barrier. In summary, this work identified a previously unknown mechanism through which exercise improves cognitive rehabilitation in epilepsy.
Expression of acyl-CoA synthetase medium-chain 3 is associated with obesity in melanoma patients and correlates with androgen receptor
Authors: Zheng* Yuan , Jiang Pingdong , Zhang Liyin
Published: May 2023

Background:

Malignant melanoma is a typical type of cancer that feature the obesity paradox.

Objectives:

We aim to evaluate the role of acyl-CoA synthetase medium-chain 3 (ACSM3) in obesity paradox in malignant melanoma (MM).

Methods:

With reproduction of the Cancer Genome Atlas (TCGA) MM dataset and validation using immunohistochemistry, we evaluated correlations of ACSM3 expression with body mass index (BMI), gender, and androgen receptor (AR) expression.

Results:

ACSM family genes were downregulated in MM and in normal skin exposed to ultraviolet. Higher expression of ACSM3 was associated with improved overall survival in men but not in women. Subgroup analysis showed the best survival outcome in obese patients with high ACSM3 expression. ACSM3 expression was significantly lower in cases with ulceration. NET-GE-based gene enrichment analysis of ACSM-overexpressed cases showed significant enrichment in lipid metabolism and butanoate metabolism. AR stood as the top possible transcription factor of ACSM3 using multiple algorithms. Expressions of ACSM3 and AR were positively correlated in obese men and overweight women. ACSM3 expression was positively correlated with BMI in men and overweight women.

Conclusion:

ACSM3 expression is associated with obesity in MM patients and correlates with AR. Functional analysis linking the findings to the obesity paradox warrants further study.

Published: May 2023

Paracentral acute middle maculopathy (PAMM) can be caused by a variety of retinal, ocular, iatrogenic, and systemic factors. Patients with PAMM typically have a sudden onset of paracentral scotomata, difficulty focusing, and/or blurred central vision. Isotretinoin is associated with multiple ocular side effects, including eye dryness and loss of night vision. In this study, we present a case of PAMM after 13 months of isotretinoin treatment with no evidence of other causes or relevant medical history.
Emerging threat of candida resistance among neonates at a teaching institute of Jharkhand
Authors: Biswas Binita , Sharma Ashok Kumar , Seema Kumari , Kumar Abhay , Boipai Manju , Kumar* Manoj
Published: May 2023

ABSTRACT

Purpose:

In the past few decades, candidemia has escalated to worrisome levels, leading to substantial morbidity and mortality in neonates. The rise in anti-fungal drug resistance demands prompt diagnosis and treatment. This study aimed to determine the speciation and susceptibility pattern of Candida species recovered from special care new-born units and identify risk factors for developing candidemia in neonates.

Method:

A total of 580 blood samples from clinically suspected septicemic neonates were collected and subjected to culture. Cultures positive for yeasts were sub-cultured on Sabouraud dextrose agar. Identification of a suspected purified colony of Candida was confirmed to the species level by both conventional and automated techniques matrix-assisted laser desorption and ionization time-of-flight mass spectrometry. Anti-fungal susceptibility of isolates was performed by an automated method (VITEK 2 system) using VITEK 2 cards. Multi-variate logistic regression analysis was used to identify risk factors associated with candidemia.

Result:

A total of 56 (9.66%) isolates of Candida species were recovered from 580 blood cultures. Non-albicans Candida species predominated with 82.14% of cases, whereas 17.86% of cases were caused by Candida albicans. Candida tropicalis (46.42%) was the most common isolate recovered, followed by Candida albicans (17.8%). Risk factor analyses identified a very low birth weight [odds ratio (OR) =4.05, 95% confidence interval (CI) =2.03–8.08] and prolonged antibiotic therapy (OR = 3.79, 95% CI = 1.7–8.7) among others as significant predictors of candidemia. All the Candida isolates showed 100% sensitivity to voriconazole and micafungin, whereas the overall sensitivities for fluconazole, amphotericin B, caspofungin, and flucytosine were 85.71%, 96.43%, 96.43%, and 91.07%, respectively.

Conclusion:

Candidemia is a life-threatening condition in neonates. Identification of Candida species and routine anti-fungal susceptibility is a must to select a suitable and effective anti-fungal therapy to revoke emerging resistance to anti-fungals.

Published: May 2023

ABSTRACT

Evidence-based health care is gaining prominence since the past many decades. The ultimate goal of evidence-based medicine is providing the best available treatment to patients. The boom in pharmacy sector has seen a rapid rise in randomised controlled clinical trials. Novel medicines or diagnostic tests must be tested before introducing to the target population. Randomised controlled trials are at the top hierarchy of evidence-based health care, especially for testing newly invented drugs. The results obtained from randomised controlled trials cannot be generalised to the entire population. This has led to the evolvement of multi-centre trials in evidence-based research. Multi-centre trials can overcome the barriers associated with single-centre clinical trials. The conduct of multi-centre trials is still in a budding stage in India. Although there are many ongoing multi-centre trials in India, very few trials are conducted among the dental fraternity. The conduct of such trials has its own set of challenges involving funding, ethical committee approval, and logistic requirements. This paper will discuss the growth of multi-centre research, steps involved in conduct of multi-centre trials, and the challenges faced in conducting these trials by the dental specialists in India.

Authors: Rajesh Ravichandran , Joseph Zeanath Cariena
Published: May 2023

ABSTRACT

Introduction:

Inclusive education is a new approach towards a system of educating children with disabilities and learning difficulties with that of normal ones within the same crown. Competency-based teacher education (CBTE) is a framework in which teachers demonstrate their learned knowledge, attitude, and skills in order to achieve specific predetermined “competencies” for a specific course or at a specific educational institution. Children with learning disabilities have significant impairment in reading, writing, and mathematics in spite of normal intelligence and sensory abilities.

Aim:

The aim of the study was to evaluate the effectiveness of competency-based teacher education (CBTE) training module on knowledge, attitude, and practices (KAP) of school teachers regarding learning disabilities in children.

Materials and Methods:

This was a Quasi experimental study carried out in the month of December 2020 using one group pretest and posttest design. Thirty-five school teachers from a private school were randomly selected as study subjects who were handling classes for primary school students at Kolar. School teachers who had prior exposure in special schools and who had already worked as a counsellor were excluded from this study. Data were collected via a self-administrated method with structured questionnaires consist of 150 items including sociodemographic profile, knowledge, attitude, and practice of teachers regarding learning disabilities in children; the data were analysed using descriptive and inferential statistics.

Results:

The findings indicated that mean post-test knowledge score was 35.89, attitude score was 170.66, and practice score was 69.60. The effectiveness of CBTE training module was found to be statistically significant at P < 0.05 in terms of mean scores enhancement in knowledge, attitude, and practices. In terms of correlation between knowledge, attitude, and practices of school teachers on learning disabilities in children, it was found that there was a highly positive correlation between attitude and practice with r = 0.884, and knowledge and practice with r = 0.905.

Conclusion:

The CBTE training module is an effective method in enhancing the knowledge, changing the desirable attitude, and developing good skills of school teachers regarding the identification and management of learning disabilities.

Published: May 2023

Introduction:

Significant surge of mucormycosis was reported in the Indian Subcontinent during the second wave of the COVID-19 pandemic. COVID-associated mucormycosis (CAM) was defined as the development of features of mucormycosis with prior or current history of COVID-19 infection. Rapid angioinvasion is an important characteristic of mucormycosis. Authors intended to find out the prevalence of retinal arterial occlusion and its association with vascular embolic occlusion elsewhere in the body among CAM patients in this study.

Methods:

This was an observational study. All consecutive-confirmed cases of mucormycosis (n = 89) and age-/gender-/risk factor-matched controls (n = 324) admitted in the designated COVID center were included in the study. All cases and controls underwent comprehensive ophthalmological, otorhinological, and neurological examinations. All necessary investigations to support the clinical diagnosis were done. Qualitative data were analyzed using the Chi-square test. Quantitative data for comparison of means between the cases and controls were done using unpaired t-test.

Results:

Twenty-one (23.59%) patients manifested the defined outcome of central retinal artery occlusion (CRAO). Among age-matched control, with similar diabetic status, none had developed the final outcome as defined (P < 0.05). About 90.47% of subjects with CRAO presented with no perception of light vision. Thirteen subjects (61.9%) with the final outcome developed clinical manifestations of stroke during the course of their illness with radiological evidence of watershed infarction (P = 0.001). Orbital debridement was performed in 9 (42.85%) subjects while orbital exenteration was done in 8 (38.09%) subjects.

Conclusions:

CRAO in CAM patients was found to have aggressive nature turning the eye blind in a very short period of time. CRAO can serve as a harbinger for subsequent development of more debilitating and life-threatening conditions such as stroke among CAM patients.

Published: May 2023

Background:

The purpose of this study was to evaluate the effect of threshold inspiratory muscle training (IMT) on the duration of weaning in intensive care unit (ICU)-admitted patients.

Materials and Methods:

This randomized clinical trial enrolled 79 ICU-admitted, mechanically ventilated patients in 2020–2021 in Imam Reza Hospital, Mashhad. Patients were randomly divided into intervention (n = 40) and control (n = 39) groups. The intervention group received threshold IMT and conventional chest physiotherapy, while the control group only received conventional chest physiotherapy once a day. Before and after the end of the intervention, the strength of inspiratory muscles and the duration of weaning were measured in both the groups.

Results:

The duration of weaning was shorter in the intervention group (8.4 ± 1.1 days) versus the control group (11.2 ± 0.6 days) (P < 0.001). The rapid shallow breathing index decreased by 46.5% in the intervention group and by 27.3% in the control group after the intervention (both P < 0.001), and the between-group comparison showed a significantly higher reduction in the intervention group than control group (P < 0.001). The patients' compliance after the intervention compared to the 1st day increased to 16.2 ± 6.6 in the intervention group and 9.6 ± 6.8 in the control group (both P < 0.001), and the between-group comparison showed a significantly higher increase in the intervention group than control group. The maximum inspiratory pressure increased by 13.7 ± 6.1 in the intervention group and by 9.1 ± 6.0 in the control group (P < 0.001). Furthermore, the weaning success was 54% more probable in the intervention group than control group (P < 0.05).

Conclusion:

The results of this study showed the positive effect of IMT with threshold IMT trainer on increased strength of respiratory muscles and reduced weaning duration.

Introduction:

Data on heart failure (HF) with mildly reduced ejection fraction (HFmrEF) is still emerging, especially in Asian populations. This study aims to compare the clinical characteristics and outcomes of Asian HFmrEF patients with those of HF patients with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF).

Methods:

Patients admitted nationally for HF between 2008 and 2014 were included in the study. They were categorised according to ejection fraction (EF). Patients with EF <40%, EF 40%–49% and EF ≥50% were categorised into the following groups: HFrEF, HFmrEF and HFpEF, respectively. All patients were followed up till December 2016. Primary outcome was all-cause mortality. Secondary outcomes included cardiovascular death and/or HF rehospitalisations.

Results:

A total of 16,493 patients were included in the study — HFrEF, n = 7,341 (44.5%); HFmrEF, n = 2,272 (13.8%); and HFpEF n = 6,880 (41.7%). HFmrEF patients were more likely to be gender neutral, of mid-range age and have concomitant diabetes mellitus, hyperlipidaemia, peripheral vascular disease and coronary artery disease (P < 0.001). The two-year overall mortality rates for HFrEF, HFmrEF and HFpEF were 32.9%, 31.8% and 29.1%, respectively. HFmrEF patients had a significantly lower overall mortality rate compared to HFrEF patients (adjusted hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.83–0.95; P < 0.001) and a significantly higher overall mortality rate (adjusted HR 1.25, 95% CI 1.17–1.33; P < 0.001) compared to HFpEF patients. This was similarly seen with cardiovascular mortality and HF hospitalisations, with the exception of similar HF hospitalisations between HFmrEF and HFpEF patients.

Conclusion:

HFmrEF patients account for a significant burden of patients with HF. HFmrEF represents a distinct HF phenotype with high atherosclerotic burden and clinical outcomes saddled in between those of HFrEF and HFpEF. Further therapeutic studies to guide management of this challenging group of patients are warranted.

Published: May 2023

Background:

Effective interventions during the coronavirus disease 2019 (COVID-19) pandemic require an understanding of patients’ knowledge and perceptions that influence their behaviour. Our study assessed knowledge of COVID-19 among kidney transplant recipients and donors, hitherto unevaluated.

Methods:

We conducted a cross-sectional survey among 325 kidney transplant recipients and 172 donors between 1 May 2020 and 30 June 2020. The survey questionnaire assessed knowledge levels of COVID-19, sociodemographic data, health status, psychosocial impact of COVID-19 and precautionary behaviours during the pandemic.

Results:

The mean COVID-19 knowledge score of the study population was 7.5 (standard deviation: 2.2) out of 10. The mean score was significantly higher among kidney recipients compared to kidney donors (7.9 [1.9] vs. 6.7 [2.6]; P <0.001). Younger age (21–49 vs. ≥50 years) and higher education (diploma and higher vs. secondary and lower) were associated with significantly higher knowledge scores in donors, but not among recipients (P-interactions ≤0.01). In both kidney recipients and donors, financial concerns and/or social isolation were associated with lower knowledge levels.

Conclusions:

Concerted efforts are needed to improve COVID-19 knowledge in kidney transplant recipients and donors, particularly older donors, donors with lower education and patients with financial concerns or feelings of social isolation. Intensive patient education may mitigate the impact of education levels on COVID-19 knowledge levels.
Volunteered Geographic Information (VGI) in Spatial Data Infrastructure (SDI) Continuum
Authors: Shahi Kamal
Published: May 2023

Spatial data infrastructure (SDI) is a system that supports the management and use of geospatial data and related resources. It involves the creation and maintenance of a network of organizations, people, and technology that enables the sharing of geospatial data across sectors and stakeholders. In recent years, the growth of geospatial data and the increasing reliance on it by various sectors has led to the emergence of new trends in SDI, such as the use of cloud computing and big data analytics, the integration of geospatial data with other types of data, and the emphasis on open data and data interoperability. Volunteered geographic information (VGI) refers to geospatial data that is collected and contributed by individuals or groups, rather than traditional sources using the application of web 2.0 and location based applications, social media, mobile devices or say citizens as the censors. Crowdsourcing in geospatial data generation concept of VGI has changed the traditional concept of SDI having one way relationship as producers and users to the user driven SDI, where user create diverse, high quality data (spatial, temporal, attribute) and also use the data interoperable, transparently, world widely and free of cost. Various authors have discussed about the application of VGI in the world of the digital data and also point outs the possibility of integration of VGI in SDI as the starting of the new generation of SDI in the form of Global GIS platform, Data Spaces, System of Systems (SoS), Geoverse, Digital Earth, Digital Twin, Virtual Geographic Environment (VGEs). However, there exists multiple VGI challenges such as data quality, data structure, data differentiation, data copyright, and data confidentiality and privacy, but with the proper cooperation and partnerships, policy and legal arrangements, standard developments, financial arrangements, inter/intra communication and added advantages of web 3.0, concept of Global Digital Ecosystem containing Geoverse, SDI and SoS is possible. Hence, VGI is the present and also the future in this SDI continuum.

Published: May 2023

INTRODUCTION: The most flexible and reliable technological system is Wi-Fi, which is made possible by a wireless connection that transmits data using radio frequencies. Wi-Fi networks, however, encounter numerous issues related to power supply, availability, efficiency, and security as a result of the various access points. While relational waves describe the medical device, Wi-Fi radios produce radio waves that are very dangerous for patients. This document offers line-of-sight communication between the transmitter and receiver using LED technology. Li-Fi technology is a method that transmits audio data using LED light, which is faster and more efficient than Wi-Fi. Since it is practically ubiquitous, light can be used for communication as well. A cutting-edge technology called optical communication includes a subset called light fidelity. By sending out visible light, the Li-Fi device enables wireless intranet communication. This paper is an in-depth study and analysis of Light Fidelity (Li-Fi), a novel technology that transmits data at high speeds over a wide spectrum by using light as a medium of transmission. The research fields that are pertinent to Li-Fi networks are thoroughly analyzed and categorized in this paper.OBJECTIVES: High speed data transmission, receive, share, broadcast through light in free space optical communication system by Li-Fi technology.METHODS: We followed some methods and developed a unique method to develop this project. which is VLC, OOK, a Lambertian discharge mechanism, LOS, NLOS, or a CMOS optical receiver.RESULTS: Successfully, we transmitted and received audio, video, and other data, which is very high-rated and near the 2 GB/s range.CONCLUSION: Visible light communication may be a fast-evolving technique in the field of wireless technology. Li-Fi is a wireless data transfer system that is both fast and inexpensive. It can also be used in potentially hazardous situations, such as in nuclear power plants, without causing electromagnetic interference. We are considering adding more features to our project in the future to get better outcomes.
ns-3 Simulation Based Exploration of LTE Handover Optimization
Authors: Nayak Sachin
Published: May 2023

Network simulator (ns-3) is a reputed simulation platform for performance evaluation of cellular networks. In this work, we explore the use of ns-3 for tracking of successful handovers (HO) and handover failures and consequent impact on 4G LTE network throughput with the aim of discovering new analytical relations about HOs and new methods to optimize the resulting throughput. Decreased cell sizes in newer generation networks lead to increasing number of handovers and handover failures that have significant impact. We begin by reviewing analytical models in the literature that aim to predict number of HO and HO failures in terms of HO control and network parameters. We initially conduct a suite of exhaustive validation studies of such analytical models, based on the simulation execution manager (SEM) for ns-3 for parallelization. Via this, we discover new causal relations relating HO failures and choice of HO control parameters on network throughput. Based on these initial results, we next evaluate the application of Gaussian process regression for prediction of instantaneous network throughput and bandit algorithms as an effective mechanism to optimize throughput over time. The new relations discovered help better understand the impact of input handover control parameters on the number of handovers and handover failures allowing us to fine tune them. The new optimization and prediction methods discovered give good gains over baseline algorithms and help accurately predict throughput respectively.

Published: May 2023

INTRODUCTION: After the covid-19 outbreak, Monkeypox has become a global pandemic putting people’s lives in jeopardy. Monkeypox has become a major concern in 40+ countries apart from Africa as scientists are struggling to clinically diagnose the virus as it looks similar with chickenpox and measles. As a part of our research, we found that to get the clinically tested result of monkey pox through polymerase chain reaction (PCR) test would take 3-4 days which is a lengthy process.OBJECTIVES: The objective of this paper is to provide a rapid identification solution which can instantly detect monkeypox virus with the help of computer vision architectures. This can be considered for preliminary examination of skin lesions and help the victim isolate themselves so that they would be cautious and can stop the spreading of virus. METHODS: Many studies have been conducted to identify the monkeypox with the help of Deep Learning models but in this study, we compare the test results obtained by deep learning CNN models AlexNet, GoogLeNet using transfer learning approach and determine the efficient model[2].RESULTS: Testing the algorithms by changing the batch sizes and number of epochs we have obtained a highest accuracy of 83.61% for AlexNet and 82.64% for GoogLeNet.CONCLUSION: AlexNet was outperforming GoogLeNet architecture in terms of validation accuracy thus providing better results.

Además, cabe destacar la alta valoración de las destrezas comunicativas proporcionadas por ambos colectivos. Por el contrario, la creatividad no es tan altamente valorada, percibiéndola especialmente como más baja el alumnado. No se observan diferencias en ninguna de las competencias valoradas por parte de ambos colectivos en función del sexo del estudiantado. Sin embargo, el alumnado si percibe que la duración de las prácticas influye en la adquisición de las competencias. Discusión y Conclusiones: Las prácticas externas son un complemento idóneo a la formación universitaria para el desarrollo de competencias. El entorno laboral es clave para que se desarrolle la creatividad y la innovación, por lo que trasladar la implementación de las destrezas comunicativas a un contexto deliberadamente creativo como el empresarial puede contribuir a mejorar las habilidades del alumnado.
„Na kupie nie”. Analne Pamiętnika z powstania warszawskiego

Not While We’re Shitting. Anality in Memoir from the Warsaw Uprising

The text presents a new approach to the Memoir from the Warsaw Uprising by Miron Białoszewski – an analysis from the perspective of anality. The article suggests that wartime suspends the usual taboo of the “privatisation of shit,” and public toilets in shelters become new “agoras,” a function which they used to perform in antiquity. Białoszewski’s quasi-anthropological account of the Uprising actually mentions toilets and the organisation of physiological life in every new place to which he and his company move during the period of two months. War is anal because it is a mass production of “waste” (corpses). However, the most important scene also connects anality to writing poetry by two young gay poets. This scene, here called Urszene, is analysed as a desublimation of homosexuality.

Współczesny rynek pracy nie tylko w Polsce, ale i na całym świecie ulega stałym przeobrażeniom. Zachodzące w tym zakresie transformacje zależą od wielu czynników. Jednym z nich, prócz zmian demograficznych, są zmiany w stosunku do aktywności zawodowej osób z różnymi niepełnosprawnościami, w tym ze spektrum autyzmu. Wyłaniające się tendencje nakreślają proces pozytywnie zachodzących zmian. I tak, w ostatnich dziesięciu latach daje się zauważyć wzrost wskaźnika zatrudnienia osób z niepełnosprawnościami, który 2019 roku w porównaniu z rokiem 2018 uległ zwiększeniu o 0,6 pkt. proc. do poziomu 26,8%. Ponadto wyniki Badania Aktywności Ekonomicznej Ludności wskazują, że w 2019 roku w porównaniu z rokiem poprzednim współczynnik aktywności zawodowej osób z niepełnosprawnościami w wieku produkcyjnym wzrósł o 0,5 pkt. proc., co stanowi wzrost o 2,9 pkt. proc. w stosunku do roku 2015 (https://niepelnosprawni. gov.pl/p,80,rynek-pracy).

A person on the autism spectrum in the labor market

Nowadays, labor markets, not only in Poland but also around the world, are undergoing constant transformation. The transitions taking place in this regard depend on many factors. In addition to demographic changes, one of them is changes in the attitudes toward labor force participation of people with various disabilities, including those on the autism spectrum. The emerging trends outline a process of positive changes. In the last ten years, an increase in the employment rates of people with disabilities can be observed as in 2019 compared to 2018, they increased by 0.6 percentage points to 26.8%. Furthermore, the results of the Badanie Aktywności Ekonomicznej Ludności (BAEL, meaning Labor Force Survey) showed that the labor force participation rate of working-age people with disabilities increased by 0.5 percentage points in 2019 compared to the previous year, being an increase of 2.9 percentage points compared to 2015 (https://niepelnosprawni.gov. pl/p,80,rynek-pracy).

Data was collected through analysing students’ assignments scripts followed by semi-structured interviews. The study sought to answer the questions:  How did the first year university students` use of words, symbols and images to convey mathematical ideas. The data were analysed using  Lave and Wenger`s (situated learning  and Seo ` mathematical communication theories. Data analysis focused on the structure and usage of symbols, images and words to commucaite  mathematical idea.  The results of the study shows that the students  experienced difficulties in using words, images and symbols to communicate the same mathematical idea. There was contradictions meanings between images, words and symbols usage in attempt to define same concept. It is recommended that encouraging studets to wave between words, symbols and images to communicate mathematica concepts will improve understanding of mathematical concepts. First year university mathematics teachers are encouraged to not only used one method of mathematical communication when definining concepts. Moreover, it is recommended that formal mathematics definition be used after students graps the meaning of concepts using everyday day words and images. The abstractness should only follow after the difinitions are understood intuitively and can be represented diagrammatically or with images.

Sometimes, it is very difficult for someone to determine whether a person wants to hear a particular music from the vast array of available choices. So, this paper has proposed a new concept of playing music that is based on the emotion of the user. The primary goal of the music recommendation system which is proposed in this paper is to offer customers recommendations that match their tastes. The most current view of the paper involves manually playing the jukebox, using wearable computers, or classifying based on auditory characteristics. Understanding the user's present emotional or mental state may result from analysing the user's facialexpression and emotions. One area is having a great possibility to provide the audience, with a vast variety of options that are based on their preferences and music and video. In this paper, the primary goal is to show a playlist of songs on any particular music application (YouTube/Spotify) based on each person’s mood. Several images of the user are collected at that precise moment using a camera with the user's consent. To determine a person's mood, these photos go through a thorough testing andtraining process. For this, the deep learning technique called CNN is used to categorize various emotions. After this, based on the trained model, the various emotions are categorized and based on this the music playlist is generated.
