The Development of STEM-nuanced Mathematics Teaching Materials to Enhance Students’ Mathematical Literacy Ability Through Information and Communication Technology-Assisted Preprospec Learning Model
Authors: Dewi Nuriana Rachmani , Maulida Nisa Farah
Published: April 2023

The mathematical literacy ability of Indonesian pupils is still relatively low, as indicated by Indonesia's score of 379 for mathematical literacy in PISA 2018. Paying attention to the learning process such as the teaching materials used in learning, is one of ways to increase mathematical literacy skills. To strengthen students' mathematical literacy skills, it is great for building qualified mathematics teaching materials with the nuances of science, technology, engineering, and mathematics (STEM) which are supported by the information and communication technology (ICT)-assisted Preprospec (Prepare, Problem Solving, Presentation and Conclusion) Learning Model. The research method used in this study is research and development (R&D), with the main reference of 4D-model development by Thiagarajan, whose stages are limited to define, design, and develop. The results showed that the feasibility test on teaching materials obtained the total average percentage of validator I to validator V, respectively, 90.19, 95.45, 93.90, 91.95, and 97.95 with very eligible criteria. It is easy to understand by students with a readability score of ρ = .109 > α = .05 or Cochran's Q = 13.091, and it can improve students' mathematical literacy skills, as evidenced by the Wilcoxon test and a gain normalization result of 485.

Türkiye’s Diaspora Engagement Policy: Change in Perspective Since 2010
Authors: KOLBAŞI-MUYAN Gizem
Published: April 2023

This paper focuses on the diaspora engagement policy of Türkiye, which affects the lives of more than 6.5 million Turkish citizens and their descendants. The main research question raised in this

paper is “What has changed in the Turkish diaspora engagement policy since 2010 with the establishment of the Presidency for Turks Abroad and Related Communities (YTB)?” Following

an analysis of the diaspora engagement policy of Türkiye in the socio-economic, political-legal and socio-cultural spheres, it is concluded that since 2010, in order to maintain a connection

with the transnational diaspora, long-distance nationalism has emerged as a prominent factor. The novelty of the policy lies in its redefinition of the target groups, the features of the diaspora,

and the policy goals, actors, tools and stakeholders. Türkiye has begun to target the reintegration of post-migrant generations with Türkiye in the socio-cultural sphere through new policy

tools, and the long-distance nationalist perspective of its diaspora engagement policy has thus led to the transformation of Türkiye into a “transnational nation-state”.

Black Lives Matter in higher education: conversations about race to transform the lived experience of Black (African-Caribbean) staff in UK universities
Authors: Warrener Julia , Douglas Vida
Published: April 2023

Academia in the UK is diminished by a lack of representation of academics from Black (African-Caribbean), Asian and South-East Asian communities. Based on data for 2019–20, only 18 per cent of academic staff at universities in the UK were from global-majority communities. This article will propose positive actions to promote greater representation and leadership opportunities, with a specific focus on Black (African-Caribbean) academics and professional staff. It will underline the importance of solidarity and collective voice to effect change, informed by the lived experience of Black staff thriving and surviving within the White spaces of UK universities. By emphasising the value of the lived experience, the article will conclude that equal representation of colleagues from Black (African-Caribbean) communities is essential not only to support student experience but also to recognise the knowledge, skills and human rights of Black (African-Caribbean), Asian and South-East Asian students and staff.

Range expansion of some non-indigenous seaweeds along the coasts of Brittany – English Channel
Authors: Burel Thomas , Helias Mathieu , Le Duff Michel
Published: April 2023

Non-indigenous seaweed species have been introduced to the coasts of Brittany, France for decades, with an increasing arrival rate since the 1970s due to both the introduction of the Pacific oyster and increased maritime traffic. In this study, seven species of red macroalgae originating from the Pacific Ocean were found in new locations around the coasts of Brittany between 2018 and 2022. The seaweed species belong to four different orders: Ceramiales (Antithamnion hubbsii, Polysiphonia morrowii, and Symphyocladiella dendroidea), Halymeniales (including Pachymeniopsis lanceolata and Polyopes lancifolius), Rhodymeniales (Botryocladia wrightii), and Gigartinales (Solieria sp.). The dispersal mode and putative invasive potential of each species were examined, and the species were described in terms of their macroscopic and microscopic appearance and habitat. These finds result from a combination of citizen science and long-term monitoring. Used together, these two approaches can aid in the detection of these species on other European coasts and in understanding their dispersion.

Diffusion induced thermal effect and stress in layered Li(Ni0.6Mn0.2Co0.2)O2 cathode materials for button lithium-ion battery electrode plates
Authors: Xu Lipeng , Tian Chongwang , Bao Chunjiang , Zhou Fei , Zhao Jinsheng
Published: April 2023

This paper develops a coupling model of the relationship between chemical reaction, temperature and stress/strain for Li (Ni0.6Mn0.2Co0.2) O2 cathode materials. With the process of reaction, the concentration of electrolyte salt changes rapidly at the beginning of diffusion and tends to dynamic equilibrium. The concentration of electrolyte LiPF6 in electrode materials diffuses from bottom to top with the process of lithium intercalation. In the process of Li-ion intercalation, the temperature rise of porous electrode materials increases sharply at first, then decreases and then increases slowly. The rate of temperature rise in the cathode material increases with the temperature decreases. The volume of electrode material deformed with the expansion along the X-axis and the radial bending along the Y-axis. And the law of stress variation with time is consistent with the temperature-time curve. By the stress-strain distribution nephogram, it is found that the position where the maximum stress is located at the edge of the upper surface, and which is most vulnerable to failure.
On stochastic dynamic modeling of incidence data
Authors: Kalligeris Emmanouil-Nektarios , Karagrigoriou Alex , Parpoula Christina
Published: April 2023

In this paper, a Markov Regime Switching Model of Conditional Mean with covariates, is proposed and investigated for the analysis of incidence rate data. The components of the model are selected by both penalized likelihood techniques in conjunction with the Expectation Maximization algorithm, with the goal of achieving a high level of robustness regarding the modeling of dynamic behaviors of epidemiological data. In addition to statistical inference, Changepoint Detection Analysis is performed for the selection of the number of regimes, which reduces the complexity associated with Likelihood Ratio Tests. Within this framework, a three-phase procedure for modeling incidence data is proposed and tested via real and simulated data.
Implementing SRIF filter with MANS-PPP software package for GNSS precise point position solution accuracy enhancement
Authors: Shehata Ashraf G. , Zarzoura Fawzi H. , El-Mewafi Mahmoud
Published: April 2023

One of the primary geodetic mapping tasks in the post-processing of GNSS data is precise point positioning (PPP). Research institutions and universities have established software packages and online PPP services in prior years. Still, it is problematic to satisfy the high-rate update criterion of PPP due to the quick growth of GNSS constellations. In PPP GNSS data processing, Square Root Information Filter SRIF is not frequently handled. In this research, we used the MANS-PPP software package to execute the processing method and generate the PPP GNSS solution. The new program has been demonstrated how can effectively enhance initial time and positioning error for multi-GNSS satellites. Processing observation data with the Kalman filter and SRIF was performed using PPP in static mode for the 16 stations, and the influence of errors has been analyzed from the filtering method. The Kalman filter was unable to maintain a stable convergence curve during the PPP filtering procedure, but SRIF was successful in doing so. Based on these findings, SRIF had better numerical stability and was well-suited for settings with PPP demanding precision computing environments.
Unmanned Aircraft Systems (UAS): Applications and Integration into Hazard Mitigation Planning
Authors: Lawson Catherine T. , Rajan Karthik Soundara
Published: April 2023

Unmanned Aircraft Systems (UAS) (also referred to as Unmanned Aerial Systems (UAS), Unmanned Autonomous Vehicles (UAVs), or drones) operations, focused on natural hazards, have experienced rapid expansion in the last decade. UAS uses before, during, and after natural hazard events, provide value for emergency management operations (e.g. Search-and-Rescue (SAR)), and post-event analytics. The Department of Homeland Security and Emergency Services (DHSES) manages UAS programs for public safety and emergency response activities in New York State. They also have the first FEMA-approved, locally adopted, web-based, interactive Hazard Mitigation Plans (HMPs). With recent advances in communication technologies (e.g. 5G), opportunities are emerging to establish a stewardship role to maximize regionwide UAS operations, including preparing for catastrophic natural hazards (e.g. earthquakes, hurricanes), leveraging existing HMPs, and incorporating new machine-learning techniques to use swarming networks before, during, and after a natural hazard event. A variety of stewardship approaches are discussed.

Evaluation of 700 patients referred with a preliminary diagnosis of biotinidase deficiency by the national newborn metabolic screening program: a single-center experience
Authors: Erdol Sahin , Kocak Tugba Akbey , Bilgin Huseyin
Published: April 2023

Objectives

This study aimed to investigate the clinical, demographic and laboratory characteristics of the patients referred with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program. We also attempted to determine the cut-off level of the fluorometric method used for screening biotinidase deficiency by the Ministry of Health.

Methods

A total of 700 subjects who were referred to the Pediatric Metabolism Outpatient Clinic with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program were retrospectively evaluated. Patients detected by family screening were excluded. Biotinidase enzyme activity was assessed and BTD gene analysis was performed in all patients.

Results

Of 700 subjects who were referred by the screening program, 284 (40.5 %) had biotinidase deficiency (BD). The enzyme activity was 0–10, 10–30 and >30 % in 39 (5.5 %), 245 (35 %) and 416 (59.5 %) patients, respectively. The BD was partial in majority of patients (86.2 %). The cut-off level was 59.5 MRU for partial BD and 50.5 MRU for profound BD. The most common mutation detected was p.Arg157His (c.470G>A) among patients with profound BD, and p.D444H (c.1330G>C) among patients with partial BD.

Conclusions

Treatment should be initiated promptly in patients who are referred by the newborn screening program. Any mean activity under 59.5 MRU should be considered partial BD, while less than 50.5 MRU should be considered profound BD. It should be kept in mind that clinical manifestations may develop both in profound and partial BD.
Quasi-bound states in the continuum with a stable resonance wavelength in dimer dielectric metasurfaces

Symmetry-protected bound states in the continuum (SP-BICs) are one of the most intensively studied BICs. Typically, SP-BICs must be converted into quasi-BICs (QBICs) by breaking the unit cell’s symmetry so that they can be accessed by the external excitation. The symmetry-broken usually results in a varied resonance wavelength of QBICs which are also highly sensitive to the asymmetry parameters. In this work, we demonstrate that QBICs with a stable resonance wavelength can be realized by breaking translational symmetry in an all-dielectric metasurface. The unit cell of metasurface is made of a silicon nanodisk dimer. The Q-factor of QBICs is precisely tuned by changing the interspacing of two nanodisks while their resonance wavelength is quite stable against the interspacing. We also find that such BICs show weak dependence on the shape of the nanodisk. Multiple decompositions indicate that the toroidal dipole dominates this type of QBIC. The resonance wavelengths of QBICs can be tuned only by changing either the lattice constants or the radius of nanodisk. Finally, we present experimental demonstrations on such a QBIC with a stable resonance wavelength. The highest measured Q-factor of QBICs is >3000. Our results may find promising applications in enhancing light–matter interaction.
Have European natural gas prices decoupled from crude oil prices? Evidence from TVP-VAR analysis
Authors: Szafranek Karol , Rubaszek Michał
Published: April 2023

Unprecedented increases in European natural gas prices observed between late 2021 and mid 2022 raise a question about the sources of these events. In this article we investigate this topic using a time-varying parameters structural vector autoregressive model for crude oil, US and European natural gas prices. This flexible framework allows us to measure how disturbances specific to the analyzed markets propagate within the system and how this propagation mechanism evolves in time. Our findings are fourfold. First, we show that oil prices are hardly affected by shocks specific to natural gas markets, whether in the US or Europe. Second, we demonstrate that oil shocks have limited impact on US natural gas prices, which points to the decoupling of both markets. Third, we evidence that over longer horizons natural gas prices in Europe are still mostly determined by oil shocks, with idiosyncratic disturbances leading to short-lived decoupling of both commodity prices. Fourth, we illustrate that along the gradual shift from oil price indexation to gas-on-gas competition, the contribution of idiosyncratic shocks to European natural gas prices has increased. Nonetheless, we discuss why the notion that EU natural gas and crude oil prices have decoupled might be premature.

Published: April 2023

The current study focused on the formulation, physicochemical characterization, and antibacterial susceptibility testing of inhalable spray dried powders containing ciprofloxacin (CIP) and polymyxin B sulfate (PMB). CIP nanosuspensions with an average particle diameter of 435.9 ± 9.3 nm were initially obtained using the wet-milling protocol and subsequently co-spray dried with PMB solutions to yield inhalable dry powders. The Powder X-Ray Diffraction (P-XRD) results showed that the wet-milled CIP nanoparticles were in a 4.8 hydrate state, which were transformed to 3.7 hydrates and amorphous materials after co-spray drying. The PMB remained in an amorphous state in the dry powders. Differential Scanning Calorimetry (DSC) analyses revealed that the glass transition temperatures (Tgs) of the co–spray dried formulations were higher than the Tg of CIP, but lower than the Tg of PMB. Fourier Transform Infrared Spectrometer (FTIR) studies suggested the existence of π - π interactions between CIP and PMB in the co-spray dried powders. These powders also retained antimicrobial effects against Pseudomonas aeruginosa strain PAO1. In addition, the spray-dried powder formulations exhibited satisfactory solid-state stability and aerodynamic characteristics when stored under 3% relative humidity and 20 ± 5 °C for 4 months. Overall, the newly developed inhalable CIP/PMB dry powders are a promising therapeutic strategy for respiratory tract infections.

Published: April 2023

Seed quality is the basis for differential crop productivity. Seed companies depend on the quality of the seeds for the seed trade, while farmers depend on the quality of the seeds to improve their productivity and secure their livelihood. Germination and varietal identification/purity are fundamental aspects of seed quality that are of prime importance to the global seed trade. Seed germination is influenced by several factors among which are the genetic factors and environmental cues of the prevailing growing conditions where the plant grows. Among these cues, climate change fundamentally affects crop development at all stages, starting from germination and seedling growth, to flowering and fruiting. Several methods have been formulated and validated for the evaluation of the varietal identification/purity for some crops, facilitate synchronised seed germination and enhance uniform field establishment for optimum crop yield in the face of climate change. This issue ofSeed Science and Technologyincludes papers discussing the application of some of the methods, for example, prechilling and the use of exogenous gibberellin to stimulate germination, the use of tetrazolium as a quick viability test for rice seeds, the applied phenol test for varietal identification of rice seeds, and seed priming to enhance germination ofCorethrodendron multijugumseeds. In addition, the physiological response of seed to soil salinity and storage environment conditions are also discussed.

Published: April 2023

This article focuses on comparing the evaluation of students’ performance using the Mean and dispersion chart grade and fixed grading method. This quantitative study was conducted in Mbulu district council. The assessment of students’ performance is one of the challenges that face assessors in secondary schools. This quantitative study investigated students’ performance by comparing their performance using statistical quality control charts grade and fixed grading method. The study used secondary data collected from 240 sampled documents obtained from academic students’ progressive reports from six ordinary secondary schools in the Mbulu District. The students’ performance is analyzed by using statistical quality control charts grade and fixed grading method. The findings revealed that in the Mean and S chart grade method, a large number of students performed well than in the fixed grading method. The mean and S chart grade method was better than fixed grading in evaluating students’ performance since it lowers the cut-off point of the individual students’ performance. The finding has implications for evaluating students’ performance because secondary school teachers can use mean and S chart grades to raise individual students’ performance in each subject.

Published: April 2023

Currently, Indonesia is experiencing a dramatic demographic shift caused by the explosion of the elderly population, or people aged 60 years and older. In 2017, Special Region of Yogyakarta was the province with the highest elderly population in Indonesia. The increase of the elderly population requires action from all parties in anticipating various problems related to the elderly, especially elderly women, including their reproductive health, mental health, and change of nutrition needed. The peri and postmenopausal period constitutes a challenging transition time for women's health, and menopausal health is a crucial aspect in healthy and successful aging. Sleman Regency Government has implemented community-based health service or elderly integrated service post. Health care volunteers (cadres) play an essential role in carrying out the objectives of an elderly integrated service post. Therefore, it requires knowledge and skills enhancement of the cadres about elderly women’s health. Training that included lectures and discussion could improve the knowledge and skills of women elderly health cadres, provide the optimal quality of health service in elderly integrated service post, and increase public awareness about the importance of health services in providing health information for the women elderly.
A case of progressive vasculopathy: angiographic characteristics and moyamoya syndrome
Authors: Gouveia Fabiana , Loja João Tiago , André Diogo , Nascimento Rafael , Freitas João Miguel , Vieira Rita , Freitas Patrício , Freitas Rafael , Costa Miguel Homem , Faria Teresa
Published: April 2023

Moyamoya Disease and Syndrome are neurological conditions that affect the blood vessels in the brain, characterized by progressive stenosis of the terminal portion of the internal carotid artery and its main branches, and the consequent network of collateral vessels at the base of the skull whose angiographic pattern simulates a "smoke cloud". Both conditions have a universal distribution, although Moyamoya Disease is more frequently seen in the Asian population. The term "Moyamoya" originates from Japanese, meaning puff of cigarette smoke, reflecting the characteristic cerebral angiogram pattern seen in these conditions. The etiology of both conditions is not yet fully understood. Moyamoya Disease corresponds to isolated vasculopathy, without risk factors for cerebrovascular disease, whereas in Moyamoya Syndrome, there is an underlying pathology. In this case report, the angiographic study and the presence of autoimmune pathology (Graves' Disease) suggest the hypothesis of Moyamoya Syndrome. The natural history of Moyamoya Disease and Syndrome varies, and they may have a slow progression with rare intercurrent events or a fulminant course with rapid neurological decline. In the absence of treatment, the progression of the disease is associated with a high risk of recurrence of neurological events. Therefore, it is crucial to consider these conditions in cases of cerebrovascular diseases.

Published: April 2023

Background: Patellar dislocation accounts for 2–3% of all knee lesions and is the second most common cause of traumatic hemarthrosis of the knee. Proper treatment is essential to minimize long term sequelae, such as recurrent dislocation, painful subluxation, and osteoarthritis. Aim: The purposes of this perspective randomized study were: 1) to evaluate the mid-term clinical and radiological results of the Elmslie–Trillat procedure for the treatment of traumatic patellar re-dislocation; and 2) to compare the results, especially radiological osteoarthritis development, with those of non-operative management for traumatic patellar re-dislocation. Methods: From June 2013 to February 2015, 65 patients were admitted to our Emergency Department for a first patellar dislocation episode. All patients were treated non-operatively. When a second episode occurred within two years, patients were randomly assigned in two groups: Group A, patients treated surgically with Elmslie-Trillat procedure, and Group B, patients were further treated non-operatively. The Knee Society Score (KSS), Lysholm scale and Kujala questionnaire were administered immediately after the re-dislocation and at the final follow-up. Tangential patella radiographs were evaluated for patellofemoral osteoarthritis and graded according to Sperner’s classification. Results: The mean follow-up was 6.4±1.7 years (range 5-8) in Group A and 6.3±2.1 years (range 5-9) in Group B. In Group A, the KSS and Lysholm scale showed significant differences between pre- and post-operatively values (p<0.05). The mean Kujala score was significantly lower in Group B when compared with the mean value of Group A (p<0.05). At the final follow-up of more than 5 five years, the mean grade of patellofemoral osteoarthritis according to Sperner’s classification changed in Group A and Group B, with respectively 25% and 29% of patients having a grade greater than or equal to 3. Conclusion: This study confirms that Elmslie-Trillat is a safe and effective procedure in the treatment of patellar instability, relieving pain and inability, and reducing recurrence risk. However, it cannot avoid the degenerative changes occurring in the natural evolution of patellar dislocation.

Conditional text generation is supposed to generate a fluent and coherent target text that is faithful to the source text. Although pre-trained models have achieved promising results, they still suffer from the crucial factuality problem. To deal with this issue, we propose a factuality-aware pretraining-finetuning framework named FactGen, which fully considers factuality during two training stages. Specifically, at the pre-training stage, we utilize a natural language inference model to construct target texts that are entailed by the source texts, resulting in a more factually consistent pre-training objective. Then, during the fine-tuning stage, we further introduce a contrastive ranking loss to encourage the model to generate factually consistent text with higher probability. Extensive experiments on three conditional text generation tasks demonstrate the effectiveness and generality of our training framework.
İlkokul Türkçe Dersi Okuma Metinlerindeki Kelime, Harf ve Hece Sıklıklarına Karşılaştırmalı Bir Bakış
Authors: KARACA Mehmet Fatih
Published: April 2023

Sıklık, metinlerin ölçülebilir özelliklerindendir. Sıklık analiziyle elde edilen veriler ilk okuma-yazma ve Türkçe dil bilgisi öğretimi, Türkçe ders kitaplarının yazımı ve değerlendirilmesi, müfredatının oluşturulması ve yenilenmesi gibi birçok konuda önemli bilgiler içerebilir. Bu çalışmada ilkokul 1, 2, 3 ve 4. sınıf Türkçe ders kitaplarında bulunan bütün okuma metinlerinin kelime, harf ve hece sıklıkları saptanmış, sonuçlar sınıf ve yayınevlerine göre kategorik olarak sunulmuştur. 1. sınıf metinleri daha az sayıda kelimeden oluşmuştur. Sınıf seviyesi arttıkça ve ilk okuma metninden son okuma metnine doğru ilerledikçe kelime sayısı da artmıştır. Kelimelerin ağırlıklı olarak 5 harfli ve 2-3 heceli olduğu, ünlü ve ünsüz uyumuna uydukları belirlenmiştir. Farklılıklar olsa da sınıf seviyeleri ve yayınevlerine göre en çok ve en az kullanılan harflerin yakın oranda seyrettiği saptanmıştır. Hecelerin en çok CV tipinde bulunduğu, ortalama hece sayısının sınıf seviyesi ve yayınevine göre benzerlik gösterdiği, bu değerin ilk okuma metinlerinde düşükken son metinlere doğru yükseldiği tespit edilmiştir. Seslerin öğretim sırasıyla harflerin kullanım sıklıklarının örtüşmediği fakat 2019 Türkçe Dersi Öğretim Programı’nın 1. grubunda yer alan harflerin sıklık oranının %47’ye ulaştığı görülmüştür. Çalışma kapsamında analiz edilenler itibariyle aynı sınıf seviyesindeki farklı yayınevlerinde birbirine yakın sonuçların alınması olağan bir durumken farklı sınıf seviyelerinde de birçok benzerlik görülmesi, sonuçların aynı veya çok yakın olması dikkat çekici ve vurgulanması gereken bir nokta olarak ortaya çıkmıştır.
Interval Prediction of Remaining Useful Life based on Convolutional Auto-Encode and Lower Upper Bound Estimation
Authors: Lyu Yi , Zhang Qichen , Chen Aiguo , Wen Zhenfei
Published: April 2023

Deep learning is widely used in remaining useful life (RUL) prediction
because it does not require prior knowledge and has strong nonlinear
fitting ability. However, most of the existing prediction methods are
point prediction. In practical engineering applications, confidence
interval of RUL prediction is more important for maintenance strategies.
This paper proposes an interval prediction model based on Long ShortTerm Memory (LSTM) and lower upper bound estimation (LUBE) for
RUL prediction. First, convolutional auto-encode network is used to
encode the multi-dimensional sensor data into one-dimensional features,
which can well represent the main degradation trend. Then, the features
are input into the prediction framework composed of LSTM and LUBE
for RUL interval prediction, which effectively solves the defect that the
traditional LUBE network cannot analyze the internal time dependence
of time series. In the experiment section, a case study is conducted using
the turbofan engine data set CMAPSS, and the advantage is validated by
carrying out a comparison with other methods.

Published: April 2023

Dyslexia is a diagnosis that is increasingly becoming a reality for students and teachers of junior high school. In the biggest part, this diagnosis becomes a surprise to both the teacher, parents, and the student because of is established in the first-second grade due to the discovery of difficulties that arise during the mastering of writing and reading. Primary school is a new step of growing up. This exciting period is often characterized by natural stress due to the lack of direct support from parents, increasing independent responsibility, competition for the teacher's attention, and the coexistence of a large number of individuals in the team. And the difficulties arising from mastering perceiving written symbols can significantly complicate the process of socialization of the child. It creates additional barriers for the student during the formation of basic educational skills. This substantially increases anxiety and lowers the child's self-esteem, building internal barriers and fears. The article presents the analysis of dyslexic disorder, presents its classification, and describes the probable causes of its occurrence. The authors present and characterize dyslexia's impact on learning and socialization processes at the example of young school students. Overcoming the difficulties of mastering graphic symbols is a long and unstable process. But the authors emphasize that dyslexia is a feature, not a sentence. Children with dyslexic disorders need understanding, help from adults, and developed modern approaches to the presentation of information, increasing the level of concentration and further mastering cognitive skills. This ensures harmonious development and learning of the student and removes barriers in communication with peers, ensuring successful socialization of the child.

The article reveals the specifics of the influence of film genres, such as horror, comedy, drama, science fiction and detective on the personality of a teenager. It is noted that each genre of the film has a unique effect on the psyche, moreover, the preference for one or another genre is determined by the internal needs of the individual, his mental state and unconscious experiences. The positive and negative features of the influence of cinema on adolescents' behavior are considered. It has been determined that a violent, aggressive, and often even meaningless or immoral film can be used to demonstrate abnormal, destructive behavior. It is noted that the main psychological mechanism of the positive influence of cinema on the personality of an adolescent is the discussion of the film, which leads adolescents to a constructive analysis of their experiences, providing "immunity" to the possible negative consequences of destructive films. It is emphasized that feedback after watching a film can not only reduce the negative impact of on-screen images but also provoke reflection and form internal patterns of behavior. The article presents the results of a study of the influence of cinema on the emotional area of an adolescent. In particular, the results were compared before and after watching the film. It was found that after watching the film, the subjects' level of anxiety slightly increased, but their level of energy, their level of elation and confidence also increased. That is, despite a slightly increased level of anxiety, it can be argued that the film had a positive effect on the emotional state of the subjects. After watching the film, teenagers showed emotional upliftment and self-confidence. The decisive role of cinema in the purposeful development of a teenager is emphasized, namely, modeling his strengths of character, forming his own life position, as well as establishing interpersonal and intergroup relationships, the ability to change infantile views to new, mature worldview positions, to form moral and aesthetic values.

The article examines the fundamental influence of human motivation on human inner and outer worlds. The views of Aristotle were used as the methodological basis to study the causality of the existence of things and phenomena, and as the theoretical basis Kurt Lewin's psychological field theory was used. The main ways of forming motivation, specifically, the upbringing process and assimilation to the social mechanism of livelihood (the relations of distribution, exchange and ownership) were researched. The connection between motivations, attitudes and dominance has been established. It is proved that motivations form a certain hierarchy of attitudes that are fixed in the human brain as dominants. The influence of motivation on the formation of human typology has been studied: dependent personality, mediocre personality, mature personality and a genius. It has been substantiated that a person of a dependent spiritual development is motivated by immediate needs, the intentions of their consciousness are directed to his body and relations of distribution, and the attitude is a stimulus. The life of a dependent person is focused on pleasure, the dominant is in the area of the striatum; behavior is dominated by the simplest forms of adaptation (stimulus - reaction), and language during communication reflects the bodily needs and desires for satisfaction. It has been further examined that a person of mediocre (reproductive) level of spiritual development is motivated by success, the intentions of his consciousness are directed to his ego, cognition of exchange relations, and attitude is the motive. The life of a mediocre person is built on the principle of reality, and the dominant migrates from the striatum to the prefrontal cortex. Behavior reproduces typical forms of behavior, and language reflects the desire for profit (economic, political, legal, psychological, ideological). It has been concluded that a person of a personal level of spiritual development is motivated by the needs of society, the intentions of their consciousness are aimed at mastering the laws of society, morality, holistic knowledge of relations of distribution, exchange and property, and interest is the attitude. The person's life is governed by duty, and the dominant is mainly in the prefrontal cortex. Behavior patterns of a mature person are focused on asserting the interests of society, and language reflects the interests of society, its values, goals and national security. Finally, it has been proved that a person of genius level of spiritual development is motivated by the need of finding the truth, the intentions of their consciousness are aimed at mastering the metaphysical laws of existence, and the ideal is the main attitude. The life of a genius is focused on creativity, the dominant is stably in the prefrontal cortex. In behavior, genius is focused on the establishment of ideals, and language reflects the ideals as a combination of Truth, Goodness and Beauty.

Authors: Patel Priyanka , Ganvir Palas , Jain Sheela
Published: April 2023

Background: Pregnancy and childbirth especially in high-risk women necessitate proper antenatal, intranasal and immediate post partum care. Lack of knowledge, ignorance and poor transport facilities are major contributors of poor pregnancy outcome. Early detection of complications and prompt referral to higher centre is crucial in improving maternal outcome.
Methods: This retrospective observational study was conducted in 700 consecutive patients who attended the department of obstetrics and gynecology Bundelkhand medical college, Sagar Madhya Pradesh. India from 1st January 2021 to 30th July 2022.
Results: Out of total patients included maximum referrals were from CHC (community health centre) i.e., 49%, followed by 25.5 and 14.6% referrals from DH (district hospital) and PHC (primary health centre) respectively. Majority of referrals from outside located CHC from Sagar district. Maximum referral reported during third trimester i.e., 58.4 and 79.2% from inside and outside Sagar respectively. Overall majority of patients referred belonged to the age group of 21 to 30 years (76.6%) and there was not significant (p=0.41) correlation between inside and outside referral.
Conclusions: Maximum referrals reported during third trimester i.e., 58.4% and 79.2% from inside and outside Sagar Districts respectively and there was statistically significant correlation (p=0.01). Antenatal care (ANC) outcome at tertiary health centre can be improved by up grading health care facilities at various peripheral health care centres.

Published: April 2023

Background: The study of maternal near miss (severe maternal morbidity) is an alternative to study of maternal death. To reduce maternal mortality ratio (MMR), analysis of maternal near miss cases provide valuable information, which helps in implementing strategies to prevent maternal death. Aims and objectives were to determine maternal near miss indices and to analyse the causes of maternal near miss and other associated factors.
Methods: A retrospective analysis of health records of maternal near miss cases admitted to tertiary care hospital from October 2021 - September 2022 was done. Patient characteristics like age, parity, gestational age, risk factors, mode of delivery, lifesaving intervention were studied.
Results: A total of 9,744 patient admitted for seeking obstetric care and out of which there were 8,791 deliveries. A total of 164 maternal near miss cases and 24 maternal deaths were found during study period. The maternal near miss incidence ratio 18.76/1000 live birth, maternal near miss to mortality ratio 6.8:1 and mortality index was 12.7%. Hypertension and its complications are the most common cause for maternal near miss cases. Women in late trimester, multiparity, low education status, lack of awareness are at increased risk of near miss cases.
Conclusions: Hypertensive disorders in pregnancy and obstetric hemorrhage are leading cause for pregnancy specific obstetric disorder and anemia was found to be a leading cause for pre-existing condition aggravated during pregnancy. This study highlights the need for overall improvement in awareness among pregnant mothers and its timely accessibility with quality critical care management.
