Is integrating video into tech-based patient education effective for improving medication adherence? – A review
Authors: Ghozali Muhammad Thesa
Published: April 2023

Patient education is a crucial part of the efforts to improve the level of medication adherence. Successful diabetes self-management will be achieved if health practitioners (doctors, pharmacists, nurses, and other health-related professionals) provide education to their patients. One of the multimedia platforms that are now popular in patient education and health promotion is video. This study primarily aimed to review published research examining integration of video-based digital interventions into tech-based patient education methods to promote medication adherence in diabetic patients. All of the articles presented in this review were collected from the PubMed, Science Direct, and Sage Publication databases. This review compared study samples, intervention characteristics (length of intervention and learning media), and adherence outcomes, as well as additional outcomes across the studies. Of the 304 articles reviewed, seven studies that met the criteria were found and included in the review. Overall, 57.14% of the integrated video-based interventions demonstrated improved medication adherence and 42.86% demonstrated improvement in other related health outcomes. The interventions were 7 weeks to 6 months in length and were in the form of storytelling with videos, smartphone apps, educational programs, or web-based education. It can be concluded that video-based digital interventions aimed to improve medication adherence in diabetic patients are promising. For optimum outcomes, this study highly suggests that a combination of video (synchronous and asynchronous) and a good patient education program is an ideal form of intervention for patients with type 2 diabetes. Regarding the education platform, the intervention could be humanoid robots, storytelling, mobile health (mHealth) apps, websites, robot-enhanced diabetes care, and other related tech-based programs or even conventional models.

Unlike common jet engine that had numerous moving components, pulse jet has no moving component. The aim of this study is to examine thrust and noise of valve less pulse jet engine with a volume of combustion chamber 668.66 cm3 , inlet standard size 2.54 cm with a length of 35.56 cm and variations in standard size outlets 2.54 cm, 5.08 cm and 1.52 cm. with air and gas comparison 1: 1 to 1: 6. Basic theories include Cadency effects, acoustics and resonance elements, waves and currents and Lenoir cycles. The material used is stainless steel plate and pipe with a thickness of 0.08 cm. First gas and air fuel are injected in the combustion chamber, spark plugs ignited spark fire and the engine process produces thrust. The thrust on the jet engine occurs because there is a change in the momentum of the gas flowing through the engine. The standard engine produces the highest thrust and noise 0.491 N and 60 dB, variations I 0.588 N and 63 dB, as well as variations II 0.442 N and 60 dB. The variation I is the most perfect engine combustion and the lowest engine temperature.

МЕТАФОРА ЯК ФОРМА ВИСЛОВЛЕННЯ ІДЕЙ
Authors: СКОМОРОВСЬКА НАТАЛІЯ
Published: April 2023

У статті розкрито роль метафори у процесі людського пізнання та створення нових понять. Проаналізовано праці відомих філософів, психологів, основні теорії трактування метафори в розвитку мислення та мовлення людини. Зроблено висновки, що інтерес до метафори виник ще з античних часів, коли її розглядали як один із способів світорозуміння, що допомагало пояснити незрозумілі явища, асоціювати їх з уже відомими. Метафора стала важливим інструментом у вивченні світоглядної системи людини, а це, у свою чергу, викликало багатобічне осмислення як окремої проблемної ситуації, так і різних періодів життя, що знаходиться у постійному русі та трансформації. Авторка звернула увагу на той факт, що з кожним десятиліттям науковий інтерес до метафори тільки зростає, цінні ідеї трансформуються у сучасні підходи. Пізнаючи та створюючи нову реальність, люди збагачують власні знання, спостерігають широкі можливості метафоричних перенесень. Метафора розглядається як потужний інструмент мислення, прийом пізнання та генерації нових ідей.

Psychological and cultural effects of different kinds of danger. An exploration based on survey data from 79 countries
Authors: Fog Agner
Published: April 2023

Individual danger and collective danger have very different effects according to the predictions of a theory called regality theory, based on evolutionary psychology. This study explores the effects of different kinds of danger on 37 different indicators of psychological and cultural responses to danger based on data from two waves of the World Values Survey, including 173,000 respondents in 79 countries.

The results show that individual danger and collective danger have very different – and often opposite – psychological and cultural effects. Collective dangers are positively correlated with many indicators related to authoritarianism, nationalism, discipline, intolerance, morality, religiosity, etc. Individual dangers have neutral or opposite correlations with many of these indicators. Infectious diseases have little or no effects on these indicators. Many previous studies that confound different kinds of danger may be misleading.

Several psychological and cultural theories are discussed in relation to these results. The observed effects of collective danger are in agreement with many of these theories while individual danger has unexpected effects. The findings are not in agreement with terror management theory and pathogen stress theory.

50 éves CML-es beteg esetét mutatjuk be, akinek a betegség diagnózisakor a Ph+ klón klonális evolúcióját (+8) észleltük. A második generációs TKI (nilotinib) kezelésre mély molekuláris remisszióba jutott betegben ez megszűnt, de a kezelés 30. hónapjában a Ph– klón evolúciója 5q- és 7-es kromoszómavesztéssel járó MDS kialakulását eredményezte. 8 hónapos masszív hemoszupportáció és lenalidomid kezelés mellett átmenetileg a Ph–, nem MDS klónból történő vérképzése visszatért és transzfúziót sem igényelt. Az allogén őssejt-transzplantációt visszautasította. 4 hónap tünetmentességet követően az MDS klón újra visszatért, és a beteg neutropeniás szepszisben meghalt.

ABSTRACT This study aimed to determine the access and utilization of dental services in a reference center for orofacial defects in the state of Bahia, Brazil. In an interview, a questionnaire was done about socio-demographic information, cleft type, specialized treatments, scheduling time and return of the consultation of 101 patients with nonsyndromic cleft lip with or without cleft palate and 101 healthy controls. In both groups the age was between 5 to 12 years old. It was observed that individuals with cleft had faster access to the dental service in relation to the control group and shorter scheduling time between the first consultation and their return. Different needs in the use of dental services were observed in the study groups with differences in relation to the specialties (p=0.000). The nonsyndromic cleft lip with or without cleft palate individuals showed socialization difficulties in the age group between 9 and 12 years and did not present difficulties in accessing primary dental care in specialized service. In conclusion, in this study NSCL±P individuals did not present difficulties in accessing the specialized dental center. To complement the comprehensive care, it is suggested the performance of educational activities of oral health, not yet fully implemented in this multidisciplinary treatment center.

RESUMO Introdução: Para a redução dos níveis do paratormônio (PTH) estão disponíveis no mercado brasileiro duas classes de medicamentos: ativadores do receptor da vitamina D (não seletivos e seletivos) e calcimiméticos. Dentre os medicamentos supracitados, o SUS disponibiliza calcitriol oral, paricalcitol e cinacalcete. Objetivos: Desenvolver análise de custo-efetividade (CE) e de impacto orçamentário (IO) do cinacalcete versus paricalcitol para pacientes em diálise com HPTS, na perspectiva do SUS. Metodologia: Foi construído um modelo de árvore de decisão para a análise de CE, que considerou o desfecho paratireoidectomia evitada e um horizonte temporal de 1 ano. Quanto à análise de IO, foram considerados dois cenários, um de demanda aferida e outro de abordagem epidemiológica, baseado nos dados da Sociedade Brasileira de Nefrologia (SBN). Resultados: A análise de CE mostrou que o uso de cinacalcete resulta em economia de R$ 1.394,64 ao ano e efetividade incremental de 0,08, em relação a paratireoidectomia evitada. A razão de CE incremental (RCEI) foi de - R$ 17.653,67 por paratireoidectomia evitada para o cinacalcete, já que se mostrou mais efetivo e mais barato comparado ao paricalcitol. Estimou-se que o IO incremental com a ampliação do uso do cinacalcete no SUS estará entre - R$ 1.640.864,62 e R$ 166.368,50 no primeiro ano, considerando os cenários principal e epidemiológico baseado nos dados da SBN. Já ao final de 5 anos após a ampliação do uso, estimou-se um impacto incremental entre - R$ 10.740.743,86 e - R$ 1.191.339,37; considerando os mesmos cenários. Conclusão: Cinacalcete foi dominante para evitar paratireoidectomias, sendo custo-efetivo.

ABSTRACT Introduction: It has been suggested that human errors during manual tracing of linear/angular cephalometric parameters can be eliminated by using computer-aided analysis. The landmarks, however, are located manually and the computer system completes the analysis. With the advent of Artificial Intelligence in the field of Dentistry, automatic location of the landmarks has become a promising tool in digital Orthodontics. Methods: Fifty pretreatment lateral cephalograms obtained from the Orthodontic department of SRM dental college (India) were used. Analysis were done by the same investigator using the following methods: WebCeph™, AutoCEPH© for Windows or manual tracing. Landmark identification was carried out automatically by Artificial Intelligence in WebCeph™ and with a mouse driven cursor in AutoCEPH©, and manually using acetate sheet and 0.3-mm pencil, ruler and a protractor. The mean differences of the cephalometric parameters obtained between the three methods were calculated using ANOVA with statistical significance set at p<0.05. Intraclass correlation coefficient (ICC) was used to determine both reproducibility and agreement between linear and angular measurements obtained from the three methods and intrarater reliability of repeated measurements. ICC value of >0.75 indicated good agreement. Results: Intraclass correlation coefficient between the three groups was >0.830, showing good level of agreement, and the value within each group was >0.950, indicating high intrarater reliability. Conclusion: Artificial Intelligence assisted software showed good agreement with AutoCEPH© and manual tracing for all the cephalometric measurements.
A “criminosa” está aqui? A pergunta pela mulher em artigos sobre tráfico de drogas de uma revista de Ciências Criminais brasileira
Authors: Braga Ana Gabriela Mendes , Ferreira Letícia Cardoso
Published: April 2023

Resumo Este artigo tem como objetivo mapear e discutir as representações construídas em torno da “criminosa” em um periódico das Ciências Criminais brasileiras, bem como demarcar ausências dessa categoria, a partir de um método jurídico feminista. Para tanto, utilizamos a análise documental, recortando uma amostra composta de artigos da Revista Brasileira de Ciências Criminais (RBCCrim) publicados nos últimos vinte anos com a temática do comércio ilícito de entorpecentes. O material foi lido sob a ótica da técnica de análise de conteúdo, direcionada pela proposta de Katharine Bartlett em Feminist Legal Methods. Ao final, no contexto de crescente aumento da criminalização da mulher e do interesse pelo tema, concluímos que, apesar de a categoria “criminosa” estar presente em grande parte da amostra, ela foi mobilizada mais de forma descritiva - para a composição de um cenário - do que como categoria analítica, a partir da reflexividade sobre gênero e crime.

Published: April 2023

Abstract Introduction Obesity is one of the main public health problem worldwide and it has a negative short- and long-term relationship with women's health. Assessment of this disorder is essential, as is a body composition assessed by dual-energy X-ray absorptiometry (DXA) with the new region of interest as the neck. Objective To verify the association between abdominal and neck fat with sleep quality in obese women. Methods The sample, obtained from a Biomedical Engineering and Health Program database, was characterized by being obese female aged between 20 and 65 years. The tests performed were anthropometric assessment, sleep quality questionnaire, physical activity level, nutritional assessment, and body composition by dual-energy X-ray absorptiometry (DXA). For statistical analysis, the Shapiro-Wilk test, t test for independent samples, Kendall's Tau, linear and multiple regression and ROC curve were used. Results The sample consisted of 15 individuals with a mean age of 45 ± 11.10 years, neck circumference of 41.50 ± 2.61 and abdominal circumference of 128.20 ± 11.62. We found no correlation between the regions of interest and the sleep quality questionnaire. Regression analysis shows non-significant statistical values for abdominal fat. The statistical test proved that the new region of interest in abdominal fat is closer to better sensitivity and has a greater relationship with sleep quality. Conclusion there was no statistically significant correlation between the regions of interest and the sleep quality questionnaire. However, the abdominal fat region of interest was the point that presented the best association with sleep quality assessed by the Pittsburgh questionnaire.

Authors: Liveric Lovro , Iljkić Dario , Jurković Zoran , Čatipović Nikša , Nuckowski Paweł , Bialas Oktawian
Published: April 2023

In this paper, the corrosion behaviour of 42CrMo4 low-alloy steel after normalizing, soft annealing, spheroidizing annealing and full annealing is investigated. 42CrMo4 is steel for quenching and tempering, and one of the widely used and studied steels due to its good combination of mechanical properties. Sometimes, it is used in the annealed condition. Nevertheless, the corrosion properties of 42CrMo4 steel are poorly studied, especially in the annealed condition. The main objective of this work is to increase the knowledge about the corrosion behaviour of the investigated alloy. The mechanical and microstructure properties of the samples after different annealing processes were characterised with hardness testing, optical and scanning electron microscopy (SEM) and X-ray diffraction (XRD). Measurements of the open-circuit potential and potentiodynamic polarisation of the samples after different annealing processes were carried out in a naturally aerated solution. It was found that the corrosion rate of the soft annealed samples was higher than that of the spherical and full annealed samples. Moreover, full annealing resulted in a significant improvement in the corrosion resistance.
ENHANCING THE MECHANICAL, THERMAL AND ELECTRICAL PROPERTIES OF ALUMINA-MWCNT HYBRID NANOFILLER REINFORCED EPOXY COMPOSITES
Authors: R Ramkumar , Chellamuthu Sabarinathan
Published: April 2023

In this work, alumina and multi-wall carbon nanotube (MWCNT) hybrid nanofiller reinforcing pure epoxy at varying weight fractions of (0.1, 0.2, 0.3, 0.4 and 0.5) w/% is investigated to enhance the mechanical, electrical and thermal properties. The porosity, tensile strength, electrical and thermal conductivity of epoxy hybrid nanocomposites are studied after the effects of the alumina-MWCNT hybrid nanofillers. The interfacial adhesion and mechanical interlocking between the hybrid nanofillers and epoxy are greatly increased with the addition of alumina and MWCNTs, thus leading to an improvement in the mechanical properties. Additionally, a uniform distribution of hybrid nanofillers results in a larger increase in the thermal and electrical conductivity. The presence of voids in specimens is gradually decreased when the nanofiller content is increased up to 0.3 w/%. The alumina-MWCNT reinforcement significantly improves the tensile strength, by 88 %, compared with pure epoxy. Similarly, the electrical and thermal conductivity increase by 85 % and 64 %, respectively, when compared with low weight fractions of the hybrid nanofiller. Agglomeration during the fabrication of nanocomposites is manageable but it is inevitable. During the formation of chains and networks, the alumina-MWCNT reinforcement of pure epoxy greatly influences the thermal conductivity. This strategy provides a prospective new concept for the use of epoxy and its composites in structural and thermal engineering applications.
EFFECTS OF THREE-DIMENSIONAL-PRINTED ZIRCONIA ALL-CERAMIC CROWNS ON PERIODONTAL HEALTH AND AESTHETICS OF PATIENTS RECEIVING ANTERIOR TOOTH AESTHETIC RESTORATION
Authors: Li Fengxian , Li Wei
Published: April 2023

The aim of this study was to evaluate the effects of three-dimensional (3D)-printed zirconia all-ceramic crowns on the periodontal tissues and aesthetics of patients receiving anterior tooth aesthetic restoration. A total of 85 patients with anterior tooth defects treated from January 2018 to October 2019 were selected. We studied zirconia all-ceramic crowns made by computer-aided design and computer-aided manufacturing (CAD/CAM) (control group) and 3D printing (observation group). The short-term restoration effects, periodontal health indices, functional recovery, long-term clinical efficacy and aesthetic effects were compared. The gingival marginal fitness of the observation group was better than that of the control group, but the control group had better tooth color matching (P < 0.05). One year after the restoration, the bleeding index, probing depth, attachment loss, gingival index and plaque index all declined in the two groups, particularly in the observation group. Both the masticatory and language functions were improved in the two groups, especially in the observation group (P < 0.05). Both 3D-printed and CAD/CAM zirconia all-ceramic crowns have better cosmetic restoration effects on the anterior teeth. However, 3D-printed zirconia all-ceramic crowns have better gingival marginal fitness, which can benefit the periodontal tissue recovery, relieve gingival inflammation, and improve masticatory and language functions.

Published: April 2023

Avustralya, 1890’larda endüstriyel bir dönüşümün eşiğindedir ve modernizmin ortaya çıkardığı bunalımlar toplumsal bir çözülmenin habercisidir. Şehir-kırsal ikiliği, işsizlik ve sınıfsal farklılaşmaya karşı Avustralyalı entelijansı, kırsal hayatın değerli kılınmasına dayalı pastoral bir romantizmi savunmuşlardır. Avustralya’nın kültürel kimliği olarak bilinen yapı, Avustralya efsanesi ismiyle kavramsallaşmıştır. Avustralya efsanesinin temeli kabul edilen kırsal, bush kavramıyla ifade edilmiş ve 1890’da Avustralya entelektüelinin şehirli hayatın sıkıcılığını, sınıf çatışmasını ve ekonomik krizle birlikte yol alan işsizliğe karşı köke dönüşü temsilen kırsal hayatın değerli kılınması, Avustralya askerinin Birinci Dünya Savaş’ında Çanakkale Cephesi’nde yer alması ve cephede gösterdiği kahramanlıkların sonucunda Anzak efsanesine dönüşmüştür. Anzak ruhu, Avustralya ulus milliyetçiliğinin başlangıcı sayılmıştır.
Çalışma, teorik çerçevede kaynak taraması, sınıflandırma, çözümleme, tenkit ve sentez sırası izlenerek oluşturulmuştur. Tarihsel süreçte Avustralya’nın kültürel kimliği ve Çanakkale Savaşı üzerine yerli ve Avustralya literatüründe konuyla alakalı yer alan çalışmalara yer verilmiştir. Çalışmada Avustralya efsanesinin temel argümanı olan bush kavramı çerçevesinde biçimlenen efsane ve geleneğin kavramsal haritası araştırılmıştır. Çalışmanın ana teması olarak Avustralya’nın kırsal yaşamında ortaya çıkmış Avustralya kültürel kimliğinin, Çanakkale Savaşı ve sonrasında ulus inşâ sürecine nasıl evrildiği analiz edilmiş ve Avustralya ulus kimliğinin inşâ sürecinde Anzak efsanesinin temel etken olup/olmadığı araştırma kapsamında değerlendirilmiştir.
Nonlinear Radiation Damping: A New Method for Dissipating Energy in Dynamic Earthquake Rupture Simulations
Authors: Barall Michael , Harris Ruth A.
Published: April 2023

Dynamic earthquake rupture simulations are used to understand earthquake mechanics and the ground shaking that earthquakes produce. These simulations can help diagnose past earthquake behavior and are also used to generate scenarios of possible future earthquakes. Traditional dynamic rupture models generally assume elastic rock response, but this can lead to peak on-fault slip rates and ground shaking that are higher than those inferred from seismological observations. Some have approached this challenge using inelastic off-fault rock behavior to dissipate energy, but the addition of inelasticity can make it difficult to select parameters and establish suitable initial conditions, and increases the model’s complexity and computational cost. We propose a new method that works by adding a nonlinear radiation damping term to the friction law, with the surrounding rocks remaining linear elastic. Our new method results in lower peak slip rates, reduced seismic radiation, and an increasing slip-weakening critical distance with increasing rupture propagation distance, all within a linear elastic model. In addition, it is easy to implement.
Minimize Frequency Overlapping of Auditory Signals using Complementary Comb Filters
Authors: Divekar Sudhir . , Nigam Manoj K.
Published: April 2023

Cochlear hearing impairment causes overlapping of auditory speech signals having close frequency contents. Such impairment arises due to the hardening of hearing cells that effects the frequency-splitting ability of inner ear. Person with such disabilities are unable to distinguish between speech signals with high-frequency correlation. This work proposes an implementation of complementary feedforward comb filters to reduce the overlapping of auditory signals. In auditory frequency overlapping, a lower frequency loses their identities due to presence of higher frequencies. Here, two complementary comb filters have been designed to match alternate critical bandwidths of audio signals. Results shown that presenting these alternate frequency bands to human ear in the even-odd index significantly minimizes the frequency overlapping and thereby improves audibility in the hearing impaired.

Published: April 2023

Structural analysis of building is taken into account for finding out the behaviors of a structure when subjected to some external force acting on building. Building structural design for seismic loads is critical for structural safety during large ground movementsBuildings with symmetrical and unsymmetrical plan geometry, strength, and stiffness are also varied. During earthquakes, structures with a symmetric distribution of stiffness and strength in plan experience combined lateral and torsional motions.Previous earthquakes, in which many reinforced concrete structures were badly damaged or collapsed, highlighted the need to assess building seismic performance. Earthquakes can cause irregular distribution of mass, stiffness and strengths i.e., unsymmetrical buildings may cause heavy damage in structural members. Buy referring this paper it is concluded that symmetric buildings perform better than un-symmetric buildings when subjected to earthquake forces.

Authors: Vajanam Kanchan  D , Waghmare M V
Published: April 2023

Concrete is a material of high importance in infrastructure and development projects. Concrete is characterized as a brittle material. In order to minimise the brittle failure, it is beneficial to add the fibers to the concrete mix without compromising the quality of concrete. The length of polypropylene fibers (PPF) and steel fiber (SF) used in concrete mixtures are 50mmand 35mmrespectively. The aimof this paper is to learn the quality of concrete and dynamic modulus of elasticity by using Ultrasonic Pulse Velocity (UPV). The percentages of polypropylene fiber are 0%, 0.3%, 0.6%, 0.7%, 1% and steel fiber are 0%, 0.1%, 0.4%, 0.7%, 1%. Comparison of conventional and Hybrid fiber-reinforced concrete (HFRC) is studied further. Experimental investigation is carried out on 18 cubes of M40 grade concrete of size 150X150X150mm for Ultrasonic Pulse Velocity (UPV) and compression test. The results show that conventional as well as fiberreinforced concrete are of excellent and of good quality with 28-day strength of 60.74 MPa. Conventional concrete has the highest pulse velocity and dynamic modulus of elasticity of 5.1903 5Øß5Ø‘Ü and 62.43 GPa. Next to it C-3-5 has a pulse velocity of 4.886 5Øß5Ø‘Ü, dynamic modulus of elasticity as 48.61 GPa and compressive strength of 61.77 MPa. Among FRCs Polypropylene fiber-reinforced concrete with 1% fiber volume fraction showed appreciable value of pulse velocity and elasticmodulus. In hybrid fiber-reinforced concrete C-3-3with 0.7%SF and 0.3% PPF has proven to have better quality as compared with other HFRCs.

Authors: Vu Dinh Hoa
Published: April 2023

This study is conducted to find solutions to support communities in coastal craft villages to transform and expand sustainable livelihoods associated with tourism development towards a blue economy. Research results show that coastal areas associated with craft villages have rich tourism resources. However, the current status of tourism exploitation here is not commensurate with the potential. In addition, the coastal communities' primary livelihood sources are mainly related to fisheries production, sedge weaving, embroidery, handicrafts, and fine arts, with economic efficiency yet to be determined. At the same time, they are facing many unsustainable challenges due to the impacts of climate change, population growth, environmental pollution, and resource depletion. Therefore, the problem for communities in coastal craft villages today is to transform their livelihoods to develop tourism to take full advantage of their advantages and bring about high and sustainable economic efficiency. The research results can be considered a valuable reference for state management agencies in proposing mechanisms and policies for sustainable socio-economic development in the current context.
