Pregnancy is a condition of broad interest across many medical and health services research domains, but one not easily identified in healthcare claims data. Our objective was to establish an algorithm to identify pregnant women and their pregnancies in claims data. We identified pregnancy-related diagnosis, procedure, and diagnosis-related group codes, accounting for the transition to International Statistical Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) diagnosis and procedure codes, in health encounter reporting on 10/1/2015. We selected women in Merative MarketScan commercial databases aged 15–49 years with pregnancy-related claims, and their infants, during 2008–2019. Pregnancies, pregnancy outcomes, and gestational ages were assigned using the constellation of service dates, code types, pregnancy outcomes, and linkage to infant records. We describe pregnancy outcomes and gestational ages, as well as maternal age, census region, and health plan type. In a sensitivity analysis, we compared our algorithm-assigned date of last menstrual period (LMP) to fertility procedure-based LMP (date of procedure + 14 days) among women with embryo transfer or insemination procedures. Among 5,812,699 identified pregnancies, most (77.9%) were livebirths, followed by spontaneous abortions (16.2%); 3,274,353 (72.2%) livebirths could be linked to infants. Most pregnancies were among women 25–34 years (59.1%), living in the South (39.1%) and Midwest (22.4%), with large employer-sponsored insurance (52.0%). Outcome distributions were similar across ICD-9 and ICD-10 eras, with some variation in gestational age distribution observed. Sensitivity analyses supported our algorithm’s framework; algorithm- and fertility procedure-derived LMP estimates were within a week of each other (mean difference: -4 days [IQR: -13 to 6 days]; n = 107,870). We have developed an algorithm to identify pregnancies, their gestational age, and outcomes, across ICD-9 and ICD-10 eras using administrative data. This algorithm may be useful to reproductive health researchers investigating a broad range of pregnancy and infant outcomes.

Published: April 2023

Background

Our study aimed to construct and validate prognostic nomograms for predicting survival for patients with Nonfunctional Pancreatic neuroendocrine tumor (NF-pNET).

Methods

This retrospective study included 1824 patients diagnosed with NF-pNET in the Surveillance, Epidemiology and End Results database between 2004 and 2016. Randomization divided the patients into training (n = 1278) and validation (n = 546) cohorts. Prognostic factors were determined using Cox regression analyses, nomograms based on AJCC 7th and 8th staging system were constructed separately. The prediction models were validated using internal validation and external validation.

Results

Age, year of diagnosis, primary tumor site, grade, 7th or 8th TNM stage, surgery, tumor size were determined as prognostic indicator to construct two nomograms. Harrell’s concordance index (C-index) of two nomograms exhibited a clinical predictive ability of 0.828 (95%CI, 0.808~0.849) vs 0.828 (95% CI, 0.808~0.849) in the internal verification. The c-index in the external validation was 0.812 (95%CI, 0.778~0.864) vs 0.814 (95% CI, 0.779~0.848). The predictive power of the two nomograms is comparable.

Conclusions

Our nomogram may be a effective tool for predicting overall survival in patients with NF-pNET. The AJCC 8th-edition system provides discrimination similar to that of the 7th-edition system.

Published: April 2023

Background

The use of motor tricycles in transporting municipal solid waste (MSW) within urban and peri-urban towns in Ghana is on the increase. This activity often leads to the introduction of pathogen-containing bioaerosols into the environment, as well as to the tricycle operators. We sought to investigate the prevalence and associated risk factors of respiratory pathogens among solid waste tricycle operators.

Methods

A cross-sectional study was conducted among 155 solid waste transporters who use motor tricycles using semi-structured interviews. Nasopharyngeal swabs were obtained from participants and screened for respiratory pathogens using Polymerase Chain Reaction (PCR).

Results

Pathogens detected in participants were SARS-CoV-2 (n = 10, 6.5%) and Streptococcus pneumoniae (n = 10, 6.5%), constituting an overall prevalence of 12.9% and co-infection rate of 1.3%. The most common self-reported symptoms were cough (n = 67, 43.2%), sore throat (n = 44, 28.4%) and difficulty in breathing (n = 22, 14.2%). Adherence to the use of gloves (n = 117, 75.5%) and nose mask (n = 110, 71.0%) was high. There was a significant association between the detection of respiratory pathogens and the use of gloves, use of more than one PPE and exposure to other pollutants (p < 0.05). Individuals who were exposed to “other pollutants” significantly had lower odds of becoming infected with respiratory pathogens (Adj. OR (95% CI): 0.119(0.015,0.938).

Conclusion

Although prevalence of respiratory pathogens is generally low, strict adherence to PPE use could further reduce its rates to even lower levels. Governmental health institutions and informal solid waste transporters should address challenges related to exposure to pollutants, use of gloves, and multiple PPE.
‘Never enough, never enough’: Institutional autobiography and gendered labour in contemporary North American women’s writing1
Authors: Sykes Rachel
Published: April 2023

This article examines the gendered experience of labour in the North American university to theorize its implications for the production of autobiographical writing. Drawing on the work of Dodie Bellamy, Roxane Gay and Heidi Julavits, I make a specifically feminist argument about time, precarity and value in academia, arguing that the job of writing creatively in the academy is complicated by the invisibilization of education and administration as well as the preponderance of women and minorities in non-permanent and therefore precarious academic roles. The authors discussed in this article all play with supposedly marginal literary forms like the diary, personal essay or blog to trouble the institutional overvaluing of canonical work and destabilize what Sarah Sharma calls a ‘patriarchal temporality’ that designates their work and lives as marginal. With a particular focus on Bellamy, who documents her repeated denial of tenure in personal and often sexually explicit writing, I want to interrogate the peculiar circularity of narrating experiences of overwork, insecurity and discrimination in the body of a text that might be read by current or future employers, as women translate their personal and leisure time into new forms of workplace productivity and commit further areas of their life to the university without the promise of liberation from or reform of its oppressive structures.

Video killed the Instagram star: The future of political communication is audio-visual
Authors: Marquart Franziska
Published: April 2023

What does the growing popularity of audio-visual platforms and vertical video mean for visual political communication? I address the opportunities and challenges of TikTok and related platforms for news media, political actors, citizens and researchers, and briefly discuss possible avenues for future academic work. These include questions related to source credibility and media literacy, the assessment of attention versus exposure, political learning and personalization. I argue that how our field engages with these questions will be decisive in the near future.

En este trabajo se procede a una revisión completa de las estampillas ibéricas sobre dolia halladas en el oppidum de Ensérune (Hérault, Francia), el yacimiento más rico en este tipo de inscripciones dentro de la epigrafía ibérica. No solo hemos realizado autopsias de las inscripciones, revisando y modificando algunas lecturas de los editores anteriores, sino que también editamos nuevos ejemplares. Acompañamos comentarios sobre aspectos paleográficos, onomásticos y lingüísticos, con el objetivo de contextualizar las inscripciones. La mayoría documentan exclusivamente el nombre aislado del artesano y solo en tres casos se usa alguna fórmula adicional. Por lo que respecta al origen de los nombres, hay un cierto equilibrio entre nombres ibéricos y galos, aunque la lengua usada siempre es la ibérica.

CHANGE IN RESILIENT MODULUS OF BASE LAYERS IN ASPHALT PAVEMENT STRUCTURES OVER TEXAS
Authors: Bastola Nitish Raj , Souliman Mena
Published: April 2023

The properties of materials change over time and the same case happens for the HMA pavement. The various components of HMA pavement such as surface, base, sub-base, and sub-grade have time related functions. In particular, the base layer which is the immediate layer below the surface, comprising of various materials such as crush aggregates and HMA also have a time related function. Among the numerous properties of the base layers which are dependent with time is its resilient modulus. Therefore, this paper correlates the effect of the change in resilient modulus with time including the various varying conditions such as rutting, thickness of base layer, precipitation, traffic, temperature, IRI index, wheel path length cracked, cracking percentage, crack length, liquid limit, plastic limit, optimum moisture content, and % fine passing below 200 sieve. Each individual factor has different effects over the resilient modulus of the base layer, but their effects are more severe when they act at once in a pavement structure.
EFFECT OF VEHICLE QUALITY AND SPEED ON THE IMPACT CHARACTERISTICS OF AN OVERPASS BRIDGE PIER
Authors: Wang Shijie , Sun Quansheng , Yang Jianxi
Published: April 2023

To study the impact of the mechanical characteristics of heavy trucks on piers under different masses and speeds, a new equivalent simplified model of heavy trucks is proposed in this paper. The reliability of the calculation model is verified by studying the pier of the G1011 Ha-Tong high-speed K302+095 separated overpass, which was subjected to impact by a heavy truck. A finite element model of a heavy truck and a pier is established using the finite element software ABAQUS, and the influence of heavy truck load and impact speed on the impact force and pier stress is analysed. Results show that the peak of impact force increases with the increase in the mass and impact speed of heavy trucks. The high-stress area of the pier is concentrated in the root and the impact position, and an inclined through-crack is formed at 45° with the pier axis. The results also reveal the influence law of the quality of heavy trucks and impact speed on the impact force and stress of the pier and provide a new theoretical basis for the anti-collision design of piers and the limitation of current specifications on the high-speed impact of heavy trucks on piers.

Authors: Akkur Erkan , Türk Fuat , Erogul Osman
Published: April 2023

Many women around the world die due to breast cancer. If breast cancer is treated in the early phase, mortality rates may significantly be reduced. Quite a number of approaches have been proposed to help in the early detection of breast cancer. A novel hybrid feature selection model is suggested in this study. This novel hybrid model aims to build an efficient feature selection method and successfully classify breast lesions. A combination of relief and binary Harris hawk optimization (BHHO) hybrid model is used for feature selection. Then, k-nearest neighbor (k-NN), support vector machine (SVM), logistic regression (LR) and naive Bayes (NB) methods are preferred for the classification task. The suggested hybrid model is tested by three different breast cancer datasets which are Wisconsin diagnostic breast cancer dataset (WDBC), Wisconsin breast cancer dataset (WBCD) and mammographic breast cancer dataset (MBCD). According to the experimental results, the relief and BHHO hybrid model improves the performance of all classification algorithms in all three datasets. For WDBC, relief-BHO-SVM model shows the highest classification rates with an of accuracy of 98.77%, precision of 97.17%, recall of 99.52%, F1-score of 98.33%, specificity of 99.72% and balanced accuracy of 99.62%. For WBCD, relief-BHO-SVM model achieves of accuracy of 99.28%, precision of 98.76%, recall of 99.17%, F1-score of 98.96%, specificity of 99.56% and balanced accuracy of 99.36%. Relief-BHO-SVM model performs the best with an accuracy of 97.44%, precision of 97.41%, recall of 98.26%, F1-score of 97.84%, specificity of 97.47% and balanced accuracy of 97.86% for MBCD. Furthermore, the relief-BHO-SVM model has achieved better results than other known approaches. Compared with recent studies on breast cancer classification, the suggested hybrid method has achieved quite good results.
Garbage classification based on a cascade neural network
Authors: Zhang Xiliang , Zhao Na , Lv Qinyuan , Ma Zhenyu , Qin Qin , Gan Weifei , Bai Jianfeng , Gan Ling
Published: April 2023

Most existing methods of garbage classification utilize transfer learning to acquire acceptable performance. They focus on some smaller categories. For example, the number of the dataset is small or the number of categories is few. However, they are hardly implemented on small devices, such as a smart phone or a Raspberry Pi, because of the huge number of parameters. Moreover, those approaches have insufficient generalization capability. Based on the aforementioned reasons, a promising cascade approach is proposed. It has better performance than transfer learning in classifying garbage in a large scale. In addition, it requires less parameters and training time. So it is more suitable to a potential application, such as deployment on a small device. Several commonly used backbones of convolutional neural networks are investigated in this study. Two different tasks, that is, the target domain being the same as the source domain and the former being different from the latter, are conducted besides. Results indicate with ResNet101 as the backbone, our algorithm outperforms other existing approaches. The innovation is that, as far as we know, this study is the first work combining a pre-trained convolutional neural network as a feature extractor with extreme learning machine to classify garbage. Furthermore, the training time and the number of trainable parameters is significantly shorter and less, respectively.
O inglês nativo como ferramenta de exclusão social
Authors: Oliveira Manuela Correa de
Published: April 2023

Este artigo apresenta parâmetros da linguística que elucidam o conceito de linguagem em seu aspecto variável no que se refere ao aprendizado de língua inglesa (NICOLAIDES et al., 2013; CORREA, 2014). O presente trabalho tem como objetivo proporcionar reflexões a respeito dos contextos em que inglês é ensinado no Brasil, atentando ao desprestígio dado a variedades que destoam de uma norma de referência, ressaltando a perversidade por detrás da busca pela fluência nativa. Para tal, são destacados processos que contribuíram para o atual status do inglês como língua global, desmistificando o conceito de falante nativo sob a luz de trabalhos que tratam da problemática, como Crystal (2003), Odlin (2003), Moita Lopes (2008) e Nicolaides et al. (2013). O ponto de chegada dessa reflexão é reforçar o debate quanto à dicotomia americano versus britânico no ensino de inglês a fim de sustentar a visão de um continuum sobre o qual se debruçam, igualmente, as variedades do inglês em sua concepção de língua global.

Authors: Olszewski Raphael , De Muylder Antoine , Siciliano Sergio
Published: April 2023

Objective: to present and to illustrate a new methodology for daily practice in cone beam computed tomography (CBCT) interpretation and reporting in cleft lip palate (CLP) non syndromic paediatric patients. The proposed protocol is based on clinical experience and on systematic search of the literature.
Material and methods: We performed two types of systematic search of articles: 1) articles related to the use of CBCT in CLP patients, and 2) articles related to the reporting and interpretation of the CBCT images by radiologists. We used two databases PubMed and Google scholar.
Results: For indications of CBCT in CLP patients we found in PubMed 378 articles and 48 articles were selected for the review; in Google scholar we found 463 articles, and 9 articles were selected for the review. 2) For reporting in CBCT we found 956 articles in PubMed, and 9 articles were selected for the review.
Conclusions: We presented the 6-steps system for interpretation and reporting information from CBCT of CLP paediatric patients: 1) Step 1 (axial view): presence or absence of bone bridge remnants of alveolar bone graft; Step 2 (3D dental tissue reconstruction): description of dental arch tooth by tooth, search for agenesis and supernumerary teeth, description of variation in the position of the tooth explaining the type of existing translation and rotation; Step 3 (coronal view): cleft palate pathway and its extension; anomaly in maxillary, ethmoid and sphenoid sinuses if existing; Step 4 (sagittal and coronal view): checking of the opening (calcification sites) of the sphenooccipital synchondrosis, and checking of anomalies of the occipital bone; Step 5 (3D bone tissue reconstruction): C1-C2 vertebra anomalies; Step 6 (3D soft tissue reconstruction): external ear anomalies. We illustrated our methodology with 46 figures from 5 CBCT of CLP patients.

Published: April 2023

O conceito de beleza segue padrões em que a aparência jovem da pele é extremamente valorizada. No entanto, o envelhecimento cutâneo trata-se de um processo natural que ocorre devido a fatores intrínsecos (genéticos, hormonais) e extrínsecos (radiação solar, poluição, má alimentação), que resultam em manifestações como flacidez, rugas, marcas de expressão, manchas e ressecamento da pele. Os produtos magistrais são fortes aliados nesses tipos de tratamentos, pois permite aos prescritores associações de ativos que atuam em todas as manifestações de uma pele envelhecida, promovendo o seu rejuvenescimento, por meio de ativos firmadores, clareadores, hidratantes, antioxidantes, dentre outros. Esse trabalho objetivou traçar o perfil das formulações magistrais que foram dispensadas para o tratamento/prevenção do envelhecimento cutâneo. Como metodologia foi realizado um estudo descritivo, transversal, qualitativo, a partir da coleta de informações do Livro Geral de Formulações aviadas de março de 2021 a maio de 2021 de uma farmácia de manipulação de Vitória -ES. A pesquisa constatou que 16,4% das formulações de uso tópico são para envelhecimento cutâneo, sendo 64,6% dessas formulações prescritas por dermatologista, na qual apresenta como público predominantemente as mulheres. Os ativos de maior frequência foram ácido hialurônico, Cerasomosides e Hyaxel® e as formas farmacêuticas mais empregadas foram creme (27,3%) e gel (21,8%). No requisito, associações entre os ativos, 23,85% apresentaram incompatibilidades. Diante dos resultados obtidos faz-se necessário a constante atuação e capacitação do farmacêutico com o propósito de evitar possíveis erros nas formulações, que possam vir a prejudicar a efetividade e a segurança do tratamento, impactando na saúde do paciente.
Inclusive Early Childhood Education: To What Extent is Inclusion of Academic Benefit to ECD Learners with Intellectual and Learning Disabilities?
Authors: Pangeti Fungayi Fortune , Mapolisa Tichaona , Chisaka Bornface Chenjerai
Published: April 2023

The extent to which inclusion is of academic benefit to ECD learners with intellectual and learning disabilities is a topical subject for discussion among educators. The participatory action research study was conducted to find out the extent to which the inclusive education practices at an ECD Centre in Harare were of academic benefit for learners with intellectual and learning disabilities. Data were generated from seven learners with intellectual and learning disabilities, teachers and parents of the learners, university lecturers and from the school administrator. Our action research cycles included teaching in the respective learner’s classes, as well as observations made on the playground.  For triangulation we combined data generated from our interviews with key participants, participant and non-participant observations, and from document analyses. The NVivo data management system was used to code data into emergent themes. We concluded that although the school was open to inclusion, the teachers were not well trained for it, and that the learners could have benefited from a more diverse curriculum to compensate for their academic challenges. Our recommendations following the research were that both the parent government ministry, and the school administration could do more for the teachers in terms of training in inclusive education practices. We also recommended that for future research opportunities, the study could be extended to include an investigation into inclusive education practices as they relate to learners with intellectual disabilities as they transition from primary school to secondary school.

Published: April 2023

Horses and chariots played a crucial social, cultural and military role in the emergence and development of early states in China. Little research, however, has explored the life histories of individual chariot horses or assessed their role as working animals. Here, the authors present a detailed zooarchaeological and palaeopathological study of eight adult male horses, used for pulling chariots, recovered from a single chariot-horse pit at the burial site of Shijia in north-western China. The characterisation of key osteological differences between chariot horses and ridden horses is offered as a contribution to the toolkit available for the archaeological investigation of human-horse interactions around the globe.

This article addresses technological and aesthetic intersections between DJing and modern video game audio modding, with the aim of elucidating a technological context that allows game scorers without programming backgrounds to practice audio design and programming for video games. Game audio modding is a form of music remix that depends on access to game audio programming and design technologies that are embedded in game code. Though modern audio modders still require access to this code to create advanced audio mods, game audio programming and design technologies have grown in accessibility, such as the audio middleware program FMOD Studio, the design and functionality of which resembles technologies used by DJs. In fact, DJs are uniquely suited to modern game audio modding, and hence game audio design and programming, as these activities necessitate looping and transitioning between musical themes, as well as designing and programming such techniques in relation to gameplay, resulting in a kind of gameplay-automated DJ for modded scores. To elucidate this point, this article will use video game music composed by Lena Raine, and its accompanying audio programming project file designed and programmed by Kevin Regamey and Power-Up Audio, for the 2018 multiplatform two-dimensional platformer game Celeste, as an instructive example.

Authors: NEZİR Merve , ÖZCAN Suat
Published: April 2023

Diş ağartma tedavileri estetik diş hekimliğinde sıklıkla tercih edilen tedavi yöntemlerinden biridir. Bu tedavilerde hidrojen peroksit ve karbamid peroksit gibi oksitleyici ajanlar kullanılmaktadır. Bu ajanlar farklı konsantrasyonda, farklı viskozitelerde ve farklı yöntemlerle uygulanabilmektedir. Bu yöntemler arasında diş hekimi tarafından muayenehanede uygulanan ofis tipi ağartma tekniği ve hastaların evlerinde uygulayabildiği ev tipi ağartma tekniği bulunmaktadır. Ofis tipi ağartma tekniğinde ağartıcı ajan olarak genellikle farklı konsantrasyonlarda hidrojen peroksit kullanılmakta, ev tipi ağartma tekniğinde ise farklı konsantrasyonlarda karbamid peroksit kullanılabilmektedir. Ev tipi ağartma tekniğinde birçok farklı ağartma ajanı kullanılabilmektedir. Bunların arasında ağartıcı diş macunları, ağartıcı jeller ve stripler (bantlar) bulunmaktadır. Ağartma tedavisi vital ve devital dişlere uygulanabilmektedir. Ağartma tedavisinin etkinliğinin artırılması amacıyla ışık ve lazer uygulaması gibi çeşitli teknikler de kullanılabilmektedir. Ağartma tedavisinin tamamlanmasının ardından etkinliğinin devam edebilmesi amacıyla hastaya renklendirici içecekleri tüketirken pipet kullanması, renklendirici yiyecek ve içeceklerin tüketiminin ardından ağızlarını çalkalamaları ve fırçalamaları tavsiye edilmektedir. Bu tavsiyelere ek olarak ağartma tedavisinin belirli periyotlarla tekrar edilmesi de gerekebilmektedir. Ağartma ajanları diş dokularında bazı değişikliklere yol açabilmekte ve bazı riskler yaratabilmektedir. Diş dokularında hassasiyete neden olması en önemli risklerdendir. Bunun yanı sıra diş eti irritasyonlarına, pulpa hasarına ve kök rezorpsiyonlarına neden olabilmektedir. Bu derlemenin amacı diş ağartma tedavilerinin ve bu tedavilerde kullanılan güncel uygulamaların gözden geçirilmesidir.

Amaç: Bu çalışmanın amacı, okul öncesi çocuğu olan annelerin emzik kullanımı konusundaki bilgi ve tutumlarını değerlendirmektir.
Gereç ve Yöntemler: Çocuklarının diş problemleri için çocuk diş hekimliği kliniğine başvuran 143 anneye yarı yapılandırılmış anket uygulandı. Sosyodemografik verilerin yanı sıra emzik kullanımına başlama yaşı ve süresi, nedenleri, temizleme yöntemi, emzik seçimini etkileyen faktörler ve emziğin zararlarına yönelik konuları içeren 31 soruluk anket formunun anneler tarafından doldurulması istendi. Verilerin dağılımında frekans analizi, istatistiksel değerlendirmede ise Ki-Kare testi kullanıldı.
Bulgular: Annelerin çoğu (% 51,7) bebeğin doğumunu takip eden ilk ayda emzik kullanımına başladığını, % 39,2’si emzik kullanım sebebinin çocuğun uykuya dalmasını kolaylaştırmak olduğunu belirtti. Emziğin en sık gece uykuya dalarken kullanıldığı (% 60,7) tespit edildi. Annelerin büyük kısmı (% 85,7) emziğin zararlı etkileri olduğunu onaylamakta ve bu annelerin % 50’si emziğin konuşma gecikmesine, % 41,3’ü ise dişlerin ileride konumlanmasına sebep olabileceğini düşünmektedir.
Sonuç: Annelerin emzik kullanımının zararları etkileri hakkında bilgi sahibi olduğu, fakat emziklerin türleri ve temizlenmesi konularında yeterli bilgiye sahip olmadıkları tespit edildi. Çocukların diş ve genel sağlığına büyük etkisi olabilen emziğin doğru kullanımı hakkında ebeveynlerin bilgilendirilmesi gerektiği düşünüldü.

ÖZ
Giriş: Bu çalışmanın amacı genel anestezi altında diş tedavisi gören engelli hastaların demografik ve operasyonel verilerinin incelenmesidir.
Gereç ve Yöntem: Çalışmamızda 2019 Ocak ile 2020 Nisan ayları arasında Üniversite hastanesinde genel anestezi altında dental tedavi görmüş, ASA 2 ve 3 sınıflamasında olan 149 engelli hastanın demografik ve operasyonel bilgileri incelendi. ASA 1 sınıflamasında olan sağlıklı çocuklar çalışmaya dahil edilmemiştir. Hastaların cinsiyet, yaş, operasyon süresi ve yapılan işlemler incelenmiştir. Hastalarda mevcut bulunan sistemik rahatsızlıklar ve çeşitleri ayrı ayrı hesaplanıp toplam sayı olarak ve yüzde olarak verilmiştir.
Bulgular: 149 engelli hastanın 96’sı erkek 53 tanesi kız hastaydı. Hastaların yaş ortalaması 15.69 ± 9.7 idi. Hastaların 136 tanesi ASA 2, 13 tanesi ASA 3 sınıfındaydı. Hasta başına ortalama yapılan işlem sayıları dolgu 8.38 ± 3.933; diş çekimi 4.80 ± 4.165; amputasyon 1.64 ± 0.841; fissür örtücü 4.12 ± 2.307 olarak hesaplandı. Hastaların 65’inde mental retardasyon (% 43.62), 33’ünde otizm (% 22.14), 36’sında epilepsi (% 24.16), 17’sinde down sendromu (% 11.4), 16’sında cerebral palsy (% 10.73), 11’ inde kardiak problem (% 7.38), 4’ünde guatr (% 2.68), 3’ünde hidrosefali (% 2.01) görüldü.
Sonuç: Günümüzde giderek yaygınlaşan genel anestezi altında diş tedavisinde, konservatif veya radikal tedavi kararı vermek için hekimlerin önünü aydınlatacak daha fazla çalışmaya ihtiyaç duyulmaktadır. Daha önce uygulanan tedavilerde hangi işlemlerin ne sıklıkta yapıldığını bilmek gelecekte yapılacak tedaviler için hekimlere yol gösterici nitelikte olacaktır.

A Rare Case Report: Oral Focal Mucinosis
Authors: CERAN DEVECİ Kübra , ÖZERCAN Mehmet Reşat
Published: April 2023

Oral focal mucinosis (OFM); It is a rare soft tissue lesion of unknown etiology. It was first described by Tomich in 1974. It usually occurs as a localized, asymptomatic pedunculated or sessile growth on the gingiva or hard palate. In the intraoral examination of a 14-year-old systemically healthy female patient who applied to our clinic with the complaint of gingival enlargement in the maxillary palate region, a well-circumscribed mass of approximately 2 cm in diameter, covered with normal mucosa, extending from the gingival to the hard palate, in the palatal region of the right first premolar and first molar teeth. The patient stated that he noticed the mass 3-4 years ago and did not experience any pain.The lesion was taken with excisional biopsy under local anesthesia and sent to the pathology department. The patient was diagnosed with OFM as a result of pathological evaluation. No recurrence after 1 year.
Challenges in combating crimes against humanity
Authors: Timofieieva Liliia
Published: April 2023

On February 24, 2022 Russian Federation started a full-scale invasion of Ukraine. It was shooting at dwellings, kindergartens, orphanages and ambulances by Russian invaders. As a result, a huge number of Ukrainians have already been killed. Damages have been caused to the Ukrainian economy, property and culture as well.The best way to deal with crimes against humanity and war crimes as well is the integration and unity of the international community in combating these crimes. Information technologies can be used both to commit criminal offenses, including those related to terrorism and war propaganda, and to combat crime. In particular, the relevant instruments to combat crimes were developed by European legislation. Moreover, it is proposed to provide additional guarantees for the implementation of decisions of international institutions against the aggressor state, to improve the mechanism for imposing sanctions on a state that has violated international agreements.Finally the human rights standards should comply with people who have committed and been involved in crimes against humanity. The civilized world should respond and ensure security with civilized methods.
Egy ikigai elemekkel bővített „legvágyottabb én” típusú online intervenció hatásvizsgálata
Authors: Pál László , Sebestyén Nóra
Published: April 2023

Háttér és célkitűzések

Az utóbbi években a pozitív pszichológiai intervenciók száma nemzetközi viszonylatban növekszik. Magyarországon, a szemlélet népszerűsége ellenére, empirikusan igazolt publikált hatásvizsgálatok nem jellemzőek. Jelen vizsgálat célja egy ikigai elemekkel bővített „legvágyottabb én” típusú intervenció hatásvizsgálata egyetemista mintán.

Módszer

A kutatás egy online megvalósuló randomizált kontrollált vizsgálat volt aktív kontrollcsoporttal, összesen 151 egyetemi hallgató részvételével. A kísérleti csoport (n = 78) egy 20 perces online írásos aktivitásban vett részt, mely egy „ikigai” (személyes erőforrások mobilizálása) és egy „legvágyottabb én” gyakorlatból (vágyott jövőbeli én elképzelése a személyes, szociális és tanulmányi/szakmai célokkal kapcsolatban) állt. A kontrollfeltétel (n = 73) hasonló elrendezést tartalmazott, csupán tartalmában tért el a kísérleti helyzettől (napi tevékenységeket részletező gyakorlatok).

Eredmények

Eredményeink alapján a 20 perces intervenció szignifikáns mértékben növelte az optimizmus, az önértékelés és az énhatékonyság szintjét, valamint eredményes volt a szorongás csökkentésében.

Következtetések

A kutatás hazánkban először igazolta empirikusan a legvágyottabb én típusú intervenció kedvező hatását. Egyrészt támogatja a nemzetközi vizsgálatok eredményeit, másrészt hozzájárul a szakirodalomhoz azáltal, hogy kibővíti a legvágyottabb én beavatkozások hatáskörét, mivel az optimizmuson kívül a pszichológiai tőke egyéb elemeit is vizsgálta (önértékelés, énhatékonyság). A kutatás továbbá jelentős gyakorlati relevanciával bír; az ikigai elemekkel bővített legvágyottabb én típusú intervenciók hatékonyan támogathatják a felsőoktatási diáktanácsadók munkáját, illetve segíthetik a középiskolai pályaválasztással kapcsolatos foglalkozásokat.
The impact of teacher collaboration on teachers’ practices and classroom interaction in EMI in higher education
Authors: Rui Xiaochen , Lo Yuen Yi
Published: April 2023

In English medium instruction (EMI) contexts, students often encounter difficulties when learning content knowledge through their second/foreign/additional language (L2). Teacher collaboration (TC) between content and language specialists has been regarded as a potential approach to facilitating student learning in these contexts, since during collaboration, teachers can become more language aware and subsequently better integrate content and language teaching. While previous research has revealed the impact of TC on student learning, little attention has been paid to how it may affect teachers’ instructional practices and classroom interaction. To fill this research gap, this quasi-experimental study invited a drama course instructor and a language instructor at a Chinese university to collaborate to revise the course objectives and instructional activities. The drama instructor then used the revised materials with the experimental class (25 students) while practising her normal content-oriented teaching in the control class (25 students). Data were collected with lesson observations and recordings in the two classes, as well as semi-structured interviews with the two teachers and selected students. Drawing on the notion of language-related episodes (LREs), this study reported the differences in classroom interaction patterns between the two classes. The findings show that through collaboration with the language teacher, the drama instructor incorporated more LREs in different aspects, especially in vocabulary and text structure, in the experimental class than in her control class. These findings yield pedagogical implications for TC and for promoting classroom interaction in the EMI classroom.

Published: April 2023

This work developed and examined a mathematical model of the transmission dynamics of tuberculosis case detection. The model's practicable invariant region/positivity solution was discovered. The model's existence and uniqueness were established. The next generation approach is used
to determine each model's fundamental reproduction rate. Nonetheless, the differential transform method (DTM) was used to solve the model, which was a set of first order nonlinear differential equations. In presenting an approximate solution to the model, the graphical comparison of the findings
with the fourth-order RungeKutta (RK4) method is very successful and trustworthy.
