Risk assessment of pressure injuries in newborns. Appropriateness of Glamorgan and NSRAS scales: a scoping review
Authors: Nicolosi Biagio , Curcio Felice , Gheorghe Maria Aurelia , Ranieri Prisco , Parente Eustachio
Published: April 2024

The newborn's skin must undergo a transition process as a result of the passage from an aqueous to an aerobic environment. This process occurs over a period of approximately 2 to 8 weeks. The skin of newborns has important anatomical and physiological differences compared to those of older children and adults. It is thin, with fewer appendages; the stratum corneum is not present; the dermal-epidermal junction is reduced; intercellular junctions are weaker; the secretions of the sebaceous glands are limited and the pH is generally neutral. All these factors make the newborn's skin more fragile to any stimulus. To have effective prevention and intervention procedures, an accurate and practical risk assessment tool should be identified as a preliminary step for adequate prevention. Unfortunately, only few validated tools are available to assess the risk of PUs in children, especially newborns. The objective of the study is to examine the adherence of the most used tools for the assessment of PU risk in newborns, in particular to make a comparison of the limits and advantages of the most frequently used tools in neonatal settings, the Glamorgan scale and NSRAS. To respond to the main objective, a scoping review of the literature was conducted. 54 studies were identified. Further analysis was conducted, which led to the exclusion of articles that did not examine the characteristics of newborn skin, the risk factors related to PUs and the appropriateness of the NSRAS and Glamorgan tools, for a final selection of 35 studies. Patients admitted to NICU represent the paediatric category most exposed to the risk of developing pressure ulcers. Factors such as reduced mobility, together with the pressure exerted by aids or devices, increase the risk of pressure injuries. The risk factors that most expose the newborn to risk are the structure of the skin and medical devices. Nurses should implement preventative measures to control the risk of PU. The use of specific tools is necessary to detect the risk of PUs in newborns and implement preventive measures. PUs risk assessment is one of the nursing care strategies for prevention. Therefore, operators need a valid, reliable, and predictive scale. Lastly, we recommend the use of NSRAS for future research and for the education of healthcare professionals in the neonatal area.
Wound care in a child suffering from Stevens-Johnson syndrome in PICU: case report
Authors: Zanetti Carlotta
Published: April 2024

Stevens-Johnson Syndrome is considered a life-threatening adverse drug reaction.  The pathogenesis of these syndromesis still unclear, but several drugs, such as anticonvulsivants and antibiotics, and especially sulfonamides, non-steroidal anti-infiammatorydrugs, and allopurinol were predominantly suspected of triggering this reaction. A 5-year-old boy patient who came to hospital attention for an urticarial reaction developed after taking amoxicillin, then a recent scarlet fever acquired by brother. Due to the worsening of the lesions, he was admitted to our PICU after being intubated for deterioration of the respiratory dynamics and safe treatment of secretions. Nursing care is crucial: care of patient hospitalized with Stevens-Johnson syndrome and Toxic Epidermal Necrolysis consists of wound care, infection prevention, comfort management, hydration and nutrition, psychosocial support, and prevention of long-term complications. For all patients with SJS and TEN, it is essential to perform a total body daily evaluation of the skin. If the dressings remain intact, it is advisable to note the appearance of visible skin and any visible exudate or staining on the outside of the intact dressings. If dressings are being removed or need to be reapplied daily, a full skin evaluation is useful.

Pancasila is the legal basis for all legal and constitutional resources in the country of Indonesia. All behavior in nationality will be governed in pancasila, especially in legal and political spheres. At present, a Indonesia tela has become an easy target for law-enforcement politicians. The law is blunt up and blunt down, can we see in the case of Jessica Wongso’s cyanide coffee. The case has been going on since 2016 - now, the final decision of the panel of judges remains a raging debate throughout Indonesia. The pancasila implementation in the case of Jessica Wongso’s is very correct with the item of 5, which is social justice for all people of Indonesia. Mirna's death was thought to have been caused by a cyanide contaminated coffee intake. Before the police put a suspect in the murder case, mass media, especially online media, together accused Jessica Wongso, as many of mirna's friends in gulping down the coffee, as the person responsible for mirna's death. In their news, without much verification and with great haste from the phase of inquiry, inquiry, to trial, some online media have judged Jessica’s, also called the trial by the press. Especially in Jessica's case, with the hope that in the future there will be no further negative effects from the giver.
PERFORMANCE IMPROVEMENT ERROR CORRECTION IN BLOCK LOW-DENSITY CODES USING CODEC COMPONENTS
Authors: Хорошайлова М.В. , Свиридова И.В. , Лялин Д.В.
Published: April 2024

на основе метода передачи суперпозиции цепей Маркова (BMST) представлен новый класс объединенных кодов с низкой плотностью проверок на четность (LDPC) для передачи на основе транспортных блоков (TБ) с целью улучшения эффективности коррекции ошибок. При кодировании предыдущие кодовые LDPC-слова, соответствующие TБ (в предыдущем временном интервале), чередуются и накладываются на текущие кодовые LDPC-слова, в результате чего получаются передаваемые кодовые слова. Для декодирования может быть использован алгоритм декодирования скользящего поля суммы-произведения или минимальной суммы, отличающийся относительно низкой задержкой декодирования. Для анализа эффективности BMST LDPC-кодов на уровне ошибки используем нижнюю границу системы передачи пакетов, использующих механизм случайного множественного доступа, которая позволяет оперативно предсказать эффективность исправления ошибок. Численные результаты показывают, что предложенные коды могут иметь производительность, приближающуюся к пропускной способности, с отрывом в 0,007 дБ от соответствующего предела Шеннона. Они также показывают, что с помощью предложенной конструкции BMST можно значительно улучшить эффективность исправления ошибок исходных блочных LDPC-кодов 5G, достигая выигрыша в кодировании до 1 дБ для каналов с аддитивным белым гауссовским шумом (АБГШ) и до 2 дБ для каналов с быстрыми замираниями

this article presents a new class of combined codes with low density parity checks (LDPC) for transmission based on transport blocks (TB) based on the Markov chain superposition transmission method (BMST) in order to improve the efficiency of error correction. During encoding, the previous LDPC code words corresponding to TB (in the previous time interval) are alternated and superimposed on the current LDPC code words, resulting in transmitted code words. For decoding, an algorithm for decoding a sliding sum-product field or a minimum sum can be used, characterized by a relatively low decoding delay. To analyze the effectiveness of BMST LDPC codes at the error level, we use the lower bound of the packet transmission system using the random multiple access mechanism, which allows us to effectively predict the effectiveness of error correction. Numerical results show that the proposed codes can have a performance approaching throughput, with a margin of 0.007 dB from the corresponding Shannon limit. They also show that using the proposed BMST design, the error correction efficiency of the original 5G block LDPC codes can be significantly improved, achieving coding gains of up to 1 dB for channels with additive white Gaussian noise (AWGN) and up to 2 dB for channels with fast fading

Authors: Smolnikov Evgeniy V. , Litovkina Alla O. , Elisyutina Olga G. , Fedenko Elena S.
Published: April 2024

Atopic dermatitis is the most common chronic inflammatory skin disease, characterized by itching, chronic recurrent course, and in most cases is associated with respiratory allergies ― allergic rhinitis and asthma. The incidence of atopic dermatitis varies from 15 to 30% or more among children and from 2 to 14% among adults in different countries. The pathophysiological mechanisms of atopic dermatitis are based on a genetic predisposition to allergies, immune dysregulation, and the influence of environmental factors. Recent studies have shown that a key feature of atopic dermatitis is a barrier defects in compromised skin which leads to increased permeability and penetration of environmental factors (e.g., microbes, allergens) and finally to allergen sensitization and to the development of specific allergic inflammation in the target organ ― the skin.
The article presents a series of clinical cases of moderate and severe atopic dermatitis, demonstrated an integrated approach to the treatment and selection of emollients, considering the phenotypic features of atopic dermatitis.

Mathematiklernen zwischen Skylla und Charybdis
Authors: Wittmann Erich Christian
Published: April 2024

Die "Hilfen", die der Lehrer dem Schüler beim Erwerb von Wissen und beim Aufbau von Verständnis im Mathematikunterricht geben kann, sind prinzipiell zweischneidig, weil sie das Verstehen auch behindern, wenn nicht gar verhindern können. Der mathematische Formalismus einerseits, mit dem Anspruch, durch begriffliche und formale Präzision Verständnis zu gewährleisten, sowie der methodische Formalismus andererseits, mit dem Anspruch, durch unterrichtliche Massnahmen die Schüler verstehen zu lehren, stellen Bedrohungen des Verstehens dar; denn weder kann man mathematisches Wissen "vermitteln", noch "Verstehen" lehren. Im Mathematikunterricht geht es deshalb darum, Hilfe zur Selbsthilfe zu geben: Wissen kann vom Schüler innerhalb eines vorgegebenen Zielrahmens nur selbst erworben werden, indem der Schüler lernt, Verantwortung für sein eigenes Lernen und Verstehen zu übernehmen .
Wer tut auch, was er lehrt?
Authors: Meier Urs P.
Published: April 2024

Die Kluft zwischen didaktischer Theorie und unterrichtlicher Praxis, zwischen Wissenschaft und Täterschaft in der Pädagogik - wie entsteht sie, und wie liesse sie sich verkleinern? Der folgende Beitrag beschäftigt sich mit der leider oft geringen Verhaltenswirksamkeit der Lehrerbildung. Er geht davon aus, dass deren stark verbaler Unterricht dafür entscheidend mitverantwortlich ist. Weil nämlich die in der Lehrerbildung praktizierten Lernformen oft im Widerspruch stehen zu den vermittelten Inhalten, gehen letztere den Subjekten nicht unter die Haut; sie bleiben ohne wirkliche Bedeutung für die beteiligten Personen. Die Hauptthese des Vortrags besagt, dass wir auch tun müssten, was wir lehren! Denn die Verhaltenswirksamkeit ist wesentlich eine Frage der kongruenten Unterrichtsgestaltung, bei der die Lernformen in Uebereinstimmung mit den vermittelten Inhalten gebracht werden. Wer eine verhaltenswirksamere Lehrerbildung will, muss darum bei der methodischen Gestaltung ihres Unterrichts ansetzen - bei der Didaktik der Lehrerbildung.

A Study on Lyrical Realism in Shen Congwen’s The Border Town: Focused on the Dialectical Image
Authors:   Sookmyung Research Institute of Humanities, Jang Sung-jun
Published: April 2024

This essay examines the elements within Shen Congwn’s novel The Border Town(1934) that evoke a sense of lyricism and sheds light on its realism. While the novel is known as a representative Chinese lyrical novel in a tranquil rural setting, depicting a romantic love story among wholesome adolescent characters, it is also replete with elements of death and cruelty that starkly contrast the pastoral atmosphere, creating a juxtaposition. The dual nature of the main elements, such as the river and love, are in constant confrontation, maintaining a dialectical relationship, ultimately giving rise to ‘opened’ image-event which forms the foundation of lyricism. Walter Benjamin’s dialectical image serve as a valuable concept that combines lyricism and realism of the novel which reproduces representation of life and present’s totality. The novel reflects Shen’s historical consciousness as an alternative to historical materialism ideology and narrative style of 5.4 and post 5.4 realism. The dialectical image of lyricism is a key concept for designating this novel as lyrical realism, as it departs from the trajectory of 5.4 realism while simultaneously renewing realism.
Community of Comparison: How can Korean and Japanese Films Make their Contemporaneity?
Authors:   Sookmyung Research Institute of Humanities, Ahn Min-hwa
Published: April 2024

Contrary to the perception that the social contexts of post-war Korea and Japan were completely different, there are also aspects of the country that were reorganized in a similar way, because post-war Japan and Korea each concealed colonialism and its legacy through aspects of complicity between the nation-state and American imperialism. In addition, the nation-states of the United States, Korea, and Japan deny this similar collusion and abandon their responsibility to respond to colonial victims. In film culture, these phenomenon are explicitly visible in the genres of liberation melodrama, idea picture, and educational documentaries produced under the US military government control in both Japan and Korea. However, at the same time, there were film cultures in Korea and Japan that expressed alternative, or “colonial differences,” and by comparing them, this article focuses on comparative film studies that emphasizes differences based on the binary opposition of Japan = empire and Korea=colony. Inotherwords,thisshowsthat“colonialdifference”andmemoryare not based on the totality of the nation, but lie on various layers such as gender, diaspora, class, and transnational local. This would be a restoration of contemporaneity between Korea and Japan, where they have responsibility to respond to each other.
Body and Literature in Atsushi Nakajima's South Seas Genre
Authors:   Sookmyung Research Institute of Humanities, Lee Sanghyuk
Published: April 2024

Atsushi Nakajima's South Seas genre of literature has been interpreted as a critique of imperialist male intellectuals or, more often than not, as an attempt to understand the colonized. However, in order to clarify this, it is necessary to look at it through the experience of the space of the South Sea and the concept of the “body” that is constructed through the collision of multiple forces. If we look at Atsushi Nakajima's South Seas genre from this perspective, we can see that the imperialist male intellectual's perspective is still present in Nakajima, but the bodies he depicts do not only reflect the primitiveness or purity of existing discourses. First of all, Nakajima Atsushi's modernity is that he sees the body as a ‘social thing’. Under the notion that the body is constructed through the collision of various social forces, purity and primordiality at the individual level become relative. From this perspective, Atsushi Nakajima connects the physical to “habit” and suggests the possibility of a new body. The body constituted by habits becomes socially constructed through the medium or concept of ‘habit-writing on the body’. Nakajima also presupposes that literature and culture are constructed by the same logic. This notion of being constructed is the negation of absolutes, and as such, it leads to the limits and possibilities of literature (culture) and fiction as a social “habit” that connects to the otherness of the unknowable (as opposed to a singularity of purity or primordiality) and reconstructs the unknowable. This is perhaps the point at which Nakajima Atsushi's literature takes on a kind of modernity that distinguishes it from other South Seas genre of literature at that time.
Synthesis of kaliophilite by alkaline fusion and ultrasonic treatment method from kaolin raw material

Published: April 2024

Mexico has important kaolin deposits, which must be assessed to obtain products with a high commercial value, such as kaliophilite as raw material for biodiesel production. Two kaolins, A and B, with approximate SiO2:Al2O3 ratios of 1 and 1.2, respectively, were used as raw materials to produce kaliophilite. Both kaolins were obtained from the municipality of Agua Blanca in the State of Hidalgo, Mexico. Kaolins are a source of Al and Si for the synthesis of kaliophilite through an alkali fusion process at 700 °C followed by ultrasonic treatment at 28 kHz to different times and for Kaolin-KOH ratios of 1:1 and 1:1.2 (mass: mass). The kaolins as received and the alkaline mixtures heat and ultrasonically treated were analyzed using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS). The most suitable kaolin for synthesizing kaliophilite was kaolin A with the Si/Al mass ratio of approximately 1, which exhibited a higher crystallinity index range from 54 to 79.6%. Higher KOH concentrations promote the amorphous material formation decreasing the kaliophilite amount. The crystallinity index was increased when the time of ultrasonic treatment was increased.

This research aims to determine assessment problems in the independent curriculum. This research is qualitative research. The research subjects were teachers at SDN 1 Melinggih Kelod, Gianyar Regency, Bali, which was implementing the independent curriculum. Data collection techniques in this research are (1) observation, (2) interviews, and (3) expert discussions. The data analysis technique in this research uses an interactive model, namely (1) data reduction, (2) data presentation, (3) drawing conclusions. The research results show that there are two problems in assessment in the independent curriculum, namely 1) assessment problems in intracurricular learning and 2) problems in the Project for Strengthening the Pancasila Student Profile (P5). The problems with assessment in intracurricular learning consist of (1) teachers have not been able to differentiate between formative and summative assessments, (2) in formative assessments, teachers assume that the form of tests used are written tests only, (3) in summative assessments, teachers understand that assessments The summative is prepared by the teacher, but in fact it is still prepared by the education office, and (4) the teacher still considers report cards to determine learning outcomes. The problem with the P5 assessment concerns teachers' misconceptions that the P5 assessment is the final assessment carried out during harvest activities. This misconception gives rise to new problems in the field of financing where schools experience problems in harvesting work events which require money to organize.

Mixed Convection of an Ag/Water Nanofluid in a Ventilated Square Cavity Containing Cold Blocks of Different Shapes
Authors: Brahimi Meryem , Benderradji Razik , Gouidmi Hamza
Published: April 2024

This research presents the results of a numerical study on mixed convection in a ventilated cavity with a central cold block of varying shapes. The direction of the forced flow of Ag/water nanofluid is perpendicular to the transverse axis (y) of the central cold block. Mixed convection is induced by cooling at the entrance of the ventilated cavity and uniformly heating its bottom wall. The governing equations for the flow of an incompressible Newtonian nanofluid are assumed to be two-dimensional, steady, and laminar. The finite volume method is employed for numerical simulations. A series of calculations are conducted to investigate the effects of key influencing factors: Reynolds number (Re = 100), Richardson number (Ri = 1), and nanoparticle volume fractions (0 ≤ ∅ ≤ 8%) on the enhancement of heat transfer. The impact of four different geometric shapes of the cold obstacle (circular, square, triangular, and elliptical) on fluid flow and heat transfer rate is also explored. The results indicate that an increase in nanoparticle volume fraction enhances the heat exchange rate in the cavity only when the geometric shape of the cold obstacle is circular. This is followed by square and triangular shapes, which approximately yield concordant results, and then the elliptical shape.
Creating a Bot-tleneck for malicious AI: Psychological methods for bot detection
Authors: Rodriguez Christopher , Oppenheimer Daniel M.
Published: April 2024

The standard approach for detecting and preventing bots from doing harm online involves CAPTCHAs. However, recent AI research, including our own in this manuscript, suggests that bots can complete many common CAPTCHAs with ease. The most effective methodology for identifying potential bots involves completing image-processing, causal-reasoning based, free-response questions that are hand coded by human analysts. However, this approach is labor intensive, slow, and inefficient. Moreover, with the advent of Generative AI such as GPT and Bard, it may soon be obsolete. Here, we develop and test various automated, bot-screening questions, grounded in psychological research, to serve as a proactive screen against bots. Utilizing hand coded free-response questions in the naturalistic domain of MTurkers recruited for a Qualtrics survey, we identify 18.9% of our sample to be potential bots, whereas Google’s reCAPTCHA V3 identified only 1.7% to be potential bots. We then look at the performance of these potential bots on our novel bot-screeners, each of which has different strengths and weaknesses but all of which outperform CAPTCHAs.
ANÁLISIS DE LA GESTIÓN DE LOS RESIDUOS SÓLIDOS DE TIPO ORGÁNICO EN LAS EMPRESAS DE COLOMBIA BASADO EN LA INFORMACIÓN DE LA ENCUESTA AMBIENTAL INDUSTRIAL EAI -2019
Authors: Torres J , Pérez M
Published: April 2024

Objetivo: El presente estudio da a conocer la problemática de la gestión de residuos por actividades de las empresas colombianas y la disposición dada empleando la información obtenida de la encuesta ambiental industrial EAI -2019 disponible por medio del Departamento Administrativo Nacional de Estadística (DANE). Materiales y Métodos: Se enfoca en la cantidad de residuos de tipo orgánico y el destino dado. Para ello se correlacionan las variables: cantidad de residuos orgánicos y cantidad de empresas que los aprovechan para su reutilización según el tipo de actividad principal. Resultados y Discusión: Se evidenció que sólo el 65% de las empresas miden los residuos generados. Cuanto mayor sea la cantidad de residuos orgánicos generados mayor es la cantidad de empresas que los aprovechan para reutilización, reciclaje u otra modalidad. La acción que predomina es entregar los residuos a un tercero que se encargue de la destinación final con 56,9% de las empresas, cifra que supera el 40,3% obtenido de la suma de vender, donar o aprovechar los residuos orgánicos. Conclusiones: Se evidencia un riesgo para la medición del cumplimiento de las metas de economía circular y para los planes de desarrollo municipales teniendo en cuenta que alrededor del 35% de las empresas no realizan la medición de los residuos. Se requiere de compromiso de las empresas para mejorar el volumen de aprovechamiento de los residuos sólidos, incluso estos pueden generar recursos adicionales de tipo económico o energético de acuerdo con el destino dado. Un buen uso de los residuos orgánicos contribuirá en la gestión de la economía circular para dar apoyo al cuidado del medio ambiente

Introduction. Total hip replacement (THR) has revolutionized the management of various hip pathologies, including acetabular fractures, which pose significant challenges due to their complex nature and debilitating effects. Acetabular fractures, resulting from high-energy trauma, present with severe pain and functional limitations, constituting a small percentage of all fractures worldwide. While THR offers promising outcomes, variability exists in functional improvement rates and postoperative complications. Aim. This prospective observational study aims to estimate the functional outcomes and complications associated with THR in patients following acetabular fractures, with a focus on guiding clinical practice and optimizing patient care. Methodology. The study included 30 patients undergoing THR after acetabular fractures or post-primary acetabular fixation. Surgical techniques involved the Kocher-Langenbeck approach and meticulous fracture management strategies. Clinical evaluation utilized the Harris Hip Score, while radiographic assessments monitored component positioning, stability, and osteolysis. Postoperative care included pain management and rehabilitation protocols. Results. The majority of patients presented with segmental defects, with intraoperative bone grafting required in 87% of cases. Significant improvements in Harris Hip scores were observed postoperatively, indicating favorable functional outcomes. A majority of patients experienced good to excellent recovery, although postoperative complications such as pain, limping, and heterotrophic ossification were noted in some cases. Radiographic evaluations revealed satisfactory component positioning and long-term survival rates. Conclusion. These findings support the role of THR in restoring functionality and improving the quality of life for affected individuals. Continued advancements and research efforts are crucial to further optimize outcomes in this challenging patient population.

The abundance of agricultural wastes from various industrialized processes has become one of the significant contributors to water pollution, particularly in the color of effluents from industrial-based palm oil mills. Inventively, this research focused on three different agro-wastes: pineapple leaves (PL), rice straw (RS), and empty fruit bunch (EFB) reinforced onto PET fabric composite and its decolorization performances by using palm oil mill final effluent discharged (POME-FED). The calcinated agro wastes/polyvinylidene fluoride (PVDF) reinforced onto the polyethylene terephthalate (PET) fabrics were prepared by using the dip-coating technique and characterized via Scanning Electron Microscopy (SEM-EDS), spectroscopy (FTIR-ATR), turbidity and color of POME-FED. It was found that the calcinated PL/PVDF/Fabric displayed the best performance in the turbidity and decolorization by 12.02 NTU, 760 ADMI, and ~60% color removal efficiency as compared with raw POME-FED (~1800 ADMI). Nevertheless, the decolorization efficiencies of RS/PVDF/Fabric and EFB/PVDF/Fabric had increased by ~37 % and ~49 %, respectively. It shows that the formation of a reinforcing layer on the PET fabric surface has improved the transparency of POME-FED. The SEM micrographs and the change of peaks at regions 1650 cm-1, 1450 cm-1, 1210 cm-1, and 990 cm-1 in composites' spectroscopies demonstrate the different patterns of these calcinated samples are various patterns that impart the strength of the composite fabric surface functionality and hydrophobicity. The reduction of the color value of effluent showed the hydrophobicity of the integrated palm oil waste coated with PET, which enables to trap of the particles in the effluent, thus this composite has potential use in the filtration of water treatment.
