Aritmiile cardiace primare sunt mult mai puţin frecvente la sugari şi copii decât la adulţi, simptomele prezentate putând fi vagi şi nespecifi ce. Deşi urgenţele reale din cauza aritmiilor instabile la copii sunt rare, este important să se identifice şi să se gestioneze în mod corespunzător cazurile. Prezentăm cazul unui copil, care se internează pentru simptomatologie respiratorie, la examenul clinic decelându-se o frecvenţă cardiacă de 214 bpm. Copilul a devenit progresiv anxios, prezentând efort respirator. Studiul electrocardiogramei a stabilit diagnosticul de tahicardie ventriculară fasculară anterioară cu tendinţa la permanentizare. Evoluţia a fost favorabilă după efectuarea cardioversiei electrice şi tratament preventiv cu Verapamil.

The off-label prescription means that medicines are administered by an unlicensed route, in an unlicensed formulation or dosage or to a child below the stated age range. The use of drugs in an off-label or unlicensed manner to treat children is widespread. Because many prescribed treatments for children have not been adequately tested in children, this population of patients remains a vulnerable one. On the one hand, prescribing off-label use drugs in children determines a lot of controversies but, one the other hand, without this possibility, could be deprived of a chance to be treated. The paper presents the widespread phenomenon of off-label us drugs in children, reflecting in scientific studies in USA and Europe. An important focus is on Romanian statistic of Sildenafil prescription and on dilemmatic use of it in pediatric cardiology unit.

Introduction. Recent meta-analyses of population-based studies show considerable heterogeneity in the prevalence of perceived and confirmed allergic reactions, as well as sensitization to cow milk ingestion. Adverse reactions to cow milk ingestion have different prevalence patterns in different age groups. There is increasing public concern about the true prevalence and a possible increase of food allergies over time, particularly among parents, child care and school staff, health care providers, regulators and food producers. Materials and methods. We performed a retrospective study of children admitted in IOMC hospital in Bucharest between January 2011 to May 2013. The primary aim of this study was to establish and compare the prevalence of confirmed allergic reactions to food in young children from IOMC hospital to known symptoms established by different researches. Results. 312 patients were evaluated with IgE panel blood test, 64 were IgE positive to cow milk protein fraction. Discussion. We found that symptoms of adverse reactions to milk are common in infants and occur regardless of GA at birth or sex. As expected, we found that more children with CMA where living in urban than rural areas. The symptoms often appear during the first year of life, even in exclusively breastfed children. Important signs and symptoms to alarm CMA were found to be failure to thrive, anemia, gastrointestinal and respiratory complains.

Ablehnungs- und Umsetzungsraten von Organtransplantationen – mögliche Ursachen und denkbare Auswege
Authors: Pfyffer von Altishofen Monika
Published: July 2021

The work deals intensively with the very complex topic of post-mortem organ donation and the question of why it is that not all organs of potential organ donors are considered in transplantation. It covers central questions of the legally and ethically required handling of dying and death. In addition to a presentation of the relevant legal situation, the statistical findings on organ transplants performed in Switzerland during the observation period, the relatively high rates of rejection and low rates of conversion of organ donations by means of retrospective analysis of the data of all in 2013 at their then place of work, the Cantonal Hospital of St. Gallen are made and their results compared with those of the national SwissPOD study. The "primary desirable goal" of the measures taken to promote organ donation appears to the author to be less the "increase in available organs, but rather reflection on dying and one's own death", which is why she would welcome an increase in the number of living wills and organ donation cards available, in order to thereby reduce the emotionally stressful proxy decisions - regardless of the will specified therein.

Vegetation survey of the Khomas Hochland in central-western Namibia: syntaxonomical descriptions
Authors: Strohbach Ben
Published: July 2021

Background: The Great Escarpment of southern Africa takes the form of an extended mountainous highland in central-western Namibia, commonly referred to as the ‘Khomas Hochland’. It is regarded as an area of high botanical diversity. Yet only few localised studies on the vegetation composition are available. The Khomas Hochland is formed on the southern part of the Damara Orogen and dominated by metamorphosed sediments. Climatically it forms a transition between the hot desert of the Namib and the slightly cooler hot steppe in the inland.Objectives: To classify and provide syntaxonomical descriptions of the vegetation of the Khomas Hochland.Methods: A dataset comprising 1151 relevés and 914 species was compiled from various surveys, mostly collected under, and to the standards of, the umbrella project ‘Vegetation Survey of Namibia’. For first classifications, the data set was reduced to a synusial set consisting of trees, shrubs, dwarf shrubs and grasses only.Results: The classification resulted in four major landscape units, being the Pre-Namib and Escarpment zone, the Khomas Hochland proper, riverine habitats as well as surrounding lowlands. The classification was further refined using Cocktail procedures to produce 30 associations, one with four sub-associations. These are described in this paper.Conclusion: A classification of synoptic data grouped the associations into five orders and one undefined cluster of associations on specialised desert habitats. Four of these orders correspond to the habitat types identified in the first classification. The fifth order, the Senegalio hereroensis–Tarchonanthoetalia camphorathi, represents high mountains of the central Khomas Hochland, which link biogeographically to the grassland biome in South Africa.
The potential impacts of the EVFTA on Vietnam’s exports of agricultural products: an application of SMART model
Authors: Doan Duc Manh , Nguyen Dac Hieu
Published: July 2021

The study aims to identify and analyze the impact of the European Union - Vietnam Free Trade Agreement (EVFTA) on Vietnam’s exports of agricultural products. The secondary data from the World Bank and the SMART model under two scenarios are applied. The simulations suggest that the tariff elimination would result in a significant increase in Vietnam’s agricultural exports. The exported value of fish products from Vietnam shows the highest increase. In one scenario, as the European Union (EU) lowers the tariff to other competing countries, Vietnam’s exports of agricultural products exhibit minor reductions compared to the other scenario. Through examining the slight reduction and the revealed comparative advantage of Vietnam, it is found that crustaceans, mollusks, and other aquatic invertebrates are among the agricultural export products of Vietnam that potentially take the most advantage from the EVFTA.

Published: July 2021

As a result of the increase in global climate change and the development of social networks, the study of ecotourism and the impact of social networks has been getting greater attention. Nonetheless, research examining the impact of social networks on ecotourism has been limited. This study investigates the relationship between ease of use, perceived usefulness, wordof-mouth (WOM), perceived trust, and tourist attitude towards ecotourism, and examines the moderating role of perceived risk on these relationships in the context of Vietnam. The regression analysis was conducted with data from answers of 231 respondents. The results show that perceived trust has the largest impact on tourist attitude towards ecotourism, which is followed by perceived usefulness. WOM communication has the least impact. The study also highlights the role of perceived risk in moderating the relationship between social networks and tourist attitudes.

Understanding decoupling: Untruthful company crisis communication in Latin America
Authors: Contreras-Pacheco Orlando E. , Claasen Cyrlene , Garrigós-Simón Fernando J.
Published: July 2021

Purpose: This work analyzes how decoupling is used by offending companies in response to environmental crisis incidents in the Latin American context. Ethical implications and its links to legitimacy are considered.Design/methodology/approach: The research relies on a multi-case study approach, where four major environmental incidents involving four natural resource companies in Venezuela, Colombia, Mexico, and Argentina are analyzed. By examining public sources, the crisis communication processes performed by these companies are studied in order to allow for the linking of theory and practice.Findings: Results obtained suggest that, in an attempt to defend their legitimacy, companies deliberately conveyed untruthful messages and decoupled their communication in crisis from reality, resulting in ethical concerns for the practice of both crisis management and crisis communication.Research limitations/implications: By emphasizing the link between legitimacy and communication in crisis scenarios, the study illustrates how decoupling (i.e., untruthful communication practices) can be performed as a crisis management strategy. However, due the constraints of case studies, it is acknowledged that the paper has limitations for generalization.Originality/value: This work identifies four different decoupling-based crisis communication strategies performed by companies, and the way these are accompanied with secondary strategies. Furthermore, by focusing on Latin America, the study reflects the potential impact that the geographical context may have on the company’s crisis communication strategy and ultimately its legitimacy.
Recent marriage and childbearing trends in Croatia and Slovenia: A comparative review
Authors: Graovac Matassi Vera , Talan Ana
Published: July 2021

The paper discusses the marriage and childbearing trends in Croatia and Slovenia from 1985 to 2017. We made a comparative review of several indicators related to marriage and childbearing trends: mean ages of women at first marriage and first childbirth, birth rates, births within and outside marriage, total fertility rate, tempo-adjusted fertility rate, age-specific fertility rates, and marriage rate. The analysis is based on the official statistical data provided by the statistical offices of both countries and Human Fertility Database. Many of the indicators, including the birth rate, total fertility rate and age-specific fertility rate, are somewhat more favourable in Slovenia than in Croatia. One of the major differences between the two countries is that in Slovenia the connection between marriage and childbearing is not as nearly significant as in Croatia.

Authors: Ledinek Lozej Špela
Published: July 2021

The paper presents various collective instruments used in the labelling, certification and branding of cheeses in the southeastern Alps of Slovenia and Italy. Based on long term ethnography it discusses four case studies of Montasio, Bovec, Tolminc, and Mohant cheeses, that were awarded protected designation of origin at European Union level. The impact of geographical indications on the local dairy chains is compared to other instruments, ranging from top-down European and national quality schemes and inventories of traditional agricultural products and heritage, to grass-root initiatives such as Slow Food instruments and local brands. The study finds substantial difference in the use and impact of geographical indications in Italy and Slovenia, as well as several ambiguous and dissonant effects in all the identified instruments.

Authors: You Ji Won , Chung Yoonsook
Published: July 2021

Traditional academic transcripts are usually restricted to demonstrating stu-dents’ achievements and experiences during college life. As an example of extended transcripts, this study aims to introduce the development process behind an end-user product for a project performance evaluation system (PPES), which supports conducting project performance evaluations and generates project performance transcripts at a university. The first part of the study described the design process of the PPES. A user group of instructors, which continuously provided feedback on the prototype design, was formed. Consequently, the PPES was successfully developed and several main inter-faces of the PPES were presented. The second part of the study analyzed user satisfaction with the PPES and the project performance transcripts it pro-duced. In general, students perceived the project performance transcripts positively, and instructors were satisfied with both the PPES and its tran-scripts. The implications of developing a project performance evaluation sys-tem were discussed.

The key goal of the paper is to study the influence of blended learning on the academic perfor-mance of students of a statistics Bluman course at the University of Ajman. The study was implemented by means of a quasi-experimental design. The sample of the study was 268 students, grouped into two groups: one experimental group (n = 135) that used blended learning; and the other a control group (n = 133) which was educated using the traditional method. The researchers prepared the achievement test as a tool of study after verifying its validity and reliability. The findings indicated significant statistical differences among the mean scores on the students’ post-test achievement in the two study groups, in favor of experimental group students, who were educated through blended learning. Furthermore, the outcomes showed that the scores of the experimental group students were diverse based on the variable of gender (in favor of females), and based on the variable of students’ academic year (supporting those students in the fourth academic year). However, no statistically significant difference was found among the students according to the variable of the college in which they studied. The study recommends that mixed learning is to be employed more broadly to include various educational fields.

The global smartphone brands were progressing aggressively over time. A sudden unexpected turbulent situation known as a global pandemic declared by the World Health Organization (WHO) about a century later in the history of human civilization stops this progress. It makes the industry bound to fall behind. This study aims to review and analyze the impact of the present pandemic situation due to Coronavirus Disease 2019 (COVID-19) on the global smartphone industry. It shows its competitive scenarios focusing on smartphone demand and supply. Thus, the study suggest a strategic approach to combat this situation. It is done by reviewing the latest literature published explicitly in 2020. The findings of this study reveal a significant negative impact of COVID-19 on global smartphone brands, primarily especially in the big markets of this industry, namely China, India, USA, Europe. Conversely, it can also positively impact the industry, especially in some developing countries. The positivity is seen due to the expanded demand for smartphones in some sectors like education, business, and entertainment media shifted online, triggering the user’s need to purchase a new smart device. Lastly, based on the understanding of the current scenario, some strategic approaches are discussed, and appropriate solutions are given for the industry to cope up with the pandemic crisis and, at the same time, how to attain success. The strategic directions given at the end can be applied to the industry’s sustainability and growth.
Visual Emotion-Aware Cloud Localization User Experience Framework Based on Mobile Location Services
Authors: Ayyal Awwad Aiman Mamdouh
Published: July 2021

Recently, the study of emotional recognition models has increased in the human-computer interaction field. With high recognition accuracy of emotions’ data, we could get immediate feedback from mobile users, get a better perception of human behavior while interacting with mobile apps, and thus make the user experience design more adaptable and intelligent. The harnessing of emotional recognition in mobile apps can dramatically enhance users’ experience. Therefore, in this paper, we propose a visual emotion-aware cloud localization user experience framework based on mobile location services. An important feature of our proposed framework is to provide a personalized mobile app based on the user’s visual emotional changes. The framework captures the emotion-aware data, process them in the cloud server, and analyze them for an immediate localization process. The first stage in the framework builds a correlation between the application’s default language and the user’s visual emotional feedback. In the second stage, the localization model loads the appropriate application’s resources and adjusts the screen features based on the real-time user’s emotion obtained in the first stage and according to the location data that the app collected from the mobile device. Our experiments demonstrate the effectiveness of the proposed framework. The results show that our proposed framework can provide a high-quality application experience in terms of a user’s emotional levels and deliver an excellent level of usability that was before not possible.

Published: July 2021

Manual time and attendance systems are still being practiced within a considerable number of universities, colleges, government departments and companies. This traditional system requires the user to fill in their timesheets or sign on the attendance sheet manually. The practice inefficient and ineffective for university’s student attendance recording due to,  i) lecturer may lose the attendance sheet, ii) student may sign for their friends, iii) student may forget to sign on the attendance sheet, and iv) challenging to monitor attendance rate and analysis. Thus, there is a necessity to change these traditional attendance recording methods to a more efficient one. The attendance rate is significant because students are more likely to succeed in academics when they attend classes consistently. As such, a mobile app, namely Smart-Hadir, is designed to overcome problems as mentioned above. Smart-Hadir is a smartphone application developed by UMS aimed to record student attendance digitally during a class session. The technology used is slightly different from the existing applications, where Smart-Hadir is not using RFID technology but rather covers NFC, QR code, and beacon technologies. Attendance could be taken either using NFC or QR code displayed on the wall using a projector or scan the available beacon. Lecturers can create class session using the Smart-Hadir anywhere and anytime. Students are then required to take their attendance either scan the QR code, search the beacon, or swiped their student card on the lecturer’s phone. The students’ attendance will be immediately captured and saved into the database. Lecturers will be able to view the statistic report, identify and e-mail absentees, as well as monitor students’ attendance behaviour. A statistical report can be generated. It shows the percentages of students’ attendance rate, absent rate, and status. The Smart-Hadir is advantageous as it can be used to capture meeting or event attendance record as well.

Published: July 2021

The strength of materials is determined by their atomic molecular structure and the process of decay of atomic molecular bonds, which must be taken into account when optimizing materials strength control technologies. The fracture photomicrograph of metal microdamage of welded joint at various moments of time, a multilevel model of flow of acoustic emission signals of materials are presented. The physical meaning, the scale level of parameters included in the model are revealed. The structure of the mathematical model of the flow of AE signals with components of its informative elements of different scale level by strength characteristics of structural materials and resource of technical objects is shown. The multilevel model of the AE signal flow is hierarchically structured, obtained by generalizing deterministic-statistical variability. It describes the process of randomly recording deterministic accumulated damages in the material both before and after the formation of a crack at the stage of waiting for its next leap. It is shown that the proposed nanotechnology of strength control of materials is reduced to non-destructive determination of parameters of prognostic homogeneous destruction, identification of which is based on multilevel modeling of time dependence of micro-crack formation, formulation of criterion of strength homogeneity, registration of AE parameters related to the model of a specific product, which can be automated processing of registration results and determination of universal strength nanoconstants from already published reference data of fatigue tests of standard material samples.
Influence of a Hydrophobic Emulsion on the Surface Properties of Coatings of Water-Dispersion Acrylic Paint
Authors: Strokova Valeria V. , Nikulina Maria V. , Baskakov Pavel S. , Abzalilova Alina V. , Esina Anastasia Y.
Published: July 2021

The existing methods of confering hydrophobic properties to various building materials are considered. Obtaining special, including hydrophobic, properties of water-emulsion paints is a very relevant task. Previously, a method was developed for producing an emulsion of a polysiloxane stabilized with polyvinyl alcohol. The paper describes the possibility of using a hydrophobisating emulsion of polyhydrosiloxane as a functional additive for an acrylic water-dispersion paint. This emulsion is capable of forming coatings on dense and porous surfaces with an adjustable contact angle up to 105 °. The use of this emulsion, with its sufficient coalescence for volumetric hydrophobization of coatings, makes it possible to obtain a high contact angle on the surface. In the paper, it was assumed that the partial introduction of small amounts (up to 10 %) of a hydrophobizing emulsion into water-dispersion paints would allow achieving the contact angle of wetting for similar coatings consisting exclusively of emulsion. It is shown that the introduction of small amounts of a hydrophobizing emulsion with an auxiliary coalescing action of ethylene glycol makes it possible to impart hydrophobic properties to the surface of the resulting coating. When the optimum concentration of ethylene glycol in the coating is reached, dissolution and transport (yield) of polysiloxane to the surface is ensured. The research carried out made it possible to develop a paint composition with a hydrophobizing emulsion with a contact wetting angle of about 100 °, which ensured the hydrophobicity of the previously hydrophilic coating of a water-dispersion acrylic paint.
Development of 3D Printing Technology with Ceramic Paste and Study of Properties of Printed Corundum Products
Authors: Dolgin Andrey S. , Makogon Aleksei I. , Bogdanov Sergey P.
Published: July 2021

Today 3D printing with ceramics is a promising direction in the development of additive technologies. In this work, we have developed a technology for printing with ceramic pastes based on aluminum oxide and wax, namely: an extruder for printing with ceramic pastes was modeled and manufactured, the composition of the slip was selected and the paste for printing was made. After choosing the print parameters, test samples were printed: a disk and a box. Since 3D printing with ceramics is just one of the stages of manufacturing ceramic products, then we selected the parameters for drying and sintering the raw material. Drying of products is necessary to burn off an excess amount of a binder (paraffin), and due to sintering; the raw material acquires final strength and mechanical characteristics. After sintering, the sintering parameters and physical and mechanical properties of the products were measured. The microstructure of the printed products was studied using scanning electron microscopy. The phase change during sintering was studied by X-ray analysis. All obtained properties were compared with a reference sample (corundum tile made of aluminum oxide of the same grade, but using traditional ceramic technology, including pressing, drying and sintering of the product). In terms of all properties, the printed ceramics are not significantly inferior to the reference sample; however, in general, the additive technology has more advantages, such as a wide variety of shapes, shorter manufacturing time for parts, and lower energy costs.

The article deals with the problems of withstanding harsh temperatures by steel and iron. The authors of the work discuss iron denser high-temperature of γ modification and maximums and minimums of impact. In addition, the article analyses the transformations of iron and anomalies of properties: peak of heat capacity, acceleration of diffusion, etc. The authors take into account the consensus on the causes of polymorphism and the theoretical model of ferromagnetism. Besides, there is a consideration of "transformation" in interaction between Fe atoms that produce anomalies of steel properties. It is necessary to note the transformation detected by anomalies of any properties including mechanical. In the presented work the authors have made an attempt to prove transformations in iron at ~650 °C on the basis of extreme values of hardness and microhardness, metallographic structure, parameters of fine structure, precipitation resistance force depending on temperature. Therefore, the analysis of literature sources on physical and mechanical properties of iron and its derivatives has been made.

The article deals with the determination of the efficiency of a multi-bladed tool equipped with inserts made of oxide-carbide cutting ceramics, depending on the microstructural parameters of the tool material. The microstructural parameters of the oxide-carbide cutting ceramic, which affect the performance of the tool, are proposed to be determined according to the electrical resistance of the tool material. In order to implement the method for determining the working capacity of the instrument, a basic design of the device for measuring the electrical resistance of the material of the instrument is proposed. The device for measuring the electrical resistance of ceramic plates consists of a body made of a dielectric material, with channels for supplying a conductive material and a groove for installing a case with a test sample. During the test, the channels are filled with a liquid conductive material, which fills the cavity formed by the channel of the case, the groove of the case and the plate itself under test. To ensure uniform filling of the cavity, after the introduction of the liquid conductive material, metal balls are installed into the channels, which are made in such a size as to ensure free sliding along the channel, but not to let the liquid pass into the upper part of the channel. The tested ceramic plate is installed in the walls of the removable case. The walls of the removable case include electrodes, which, when the device is in operation, are inserted into a cavity with a liquid conductive material at one end, and are connected to an ohmmeter at the other. Using a device for measuring the electrical resistance of ceramic plates, it is possible to determine the operability of the tool and guarantee its operation without rejection for a certain period of time, which was confirmed by experimental research in the milling of workpieces of machine parts made of gray cast iron. Experimental studies in multi-edge machining with cutters with different values ​​of electrical resistance of ceramic plates made it possible to plot graphs of the dependence of the quality of machining during milling on the operability of the tool and on the time of the machining process.

Published: July 2021

The paper considers the applications of foamed glassy phosphate materials as carriers of biologically active substances. One of the advantages of phosphate materials is their ability to effectively support the life of microorganisms. This feature of phosphate glassy materials opens up the prospects for the application of microorganism strains - destructors of oil products to their foamed samples, that is, the creation of biosorbents for purification of water and soil from hydrocarbon contamination. The advantages of a biosorbent are explained by the high biological activity of microorganisms on the surface of foamed glassy phosphates and the possibility of active development of microorganisms with the simultaneous destruction of petrochemical contaminants. The use of biosorbent eliminates the problem of its utilization and regeneration, thus it is suitable for repeated use. The formation of porous glassy phosphate materials on the surface by the method of molecular layering of monolayer coatings allows obtaining chemically modified composite materials, which improves their performance characteristics such as strengthening the material structure with a simultaneous increase in the catalytic activity of biochemical processes.

This paper presents the results of the application of new unique techniques based on plasma nanotechnology in metallurgy and materials science. In recent years, a team of authors have developed the solutions for extraordinary problems arising in the conditions of metallurgical enterprises related to the production of synthetic materials and control of manufactured products, namely, the methods for the production of various structural materials and optimization of methods for their non-destructive testing by atomic emission spectral analysis (AESA). The paper points out some aspects of ongoing research, in particular, an innovative technique that allows obtaining ultrapure samples of white corundum by plasma melting of alumina in a reactor. This method also allows obtaining ultrapure aluminum at the output, which can be used for the purposes of hydrogen energy. In the course of the research, the criteria for thermal protection, temperature conditions and optimal parameters of the plasmatron were determined. In order to carry out the studies of metals and alloys by AESA method, a new global analytical method was developed, which made it possible to take into account the influence of various important parameters, including third elements, background plasma radiation, etc. This method has been preliminary tested on emission spectrometers made in Russia and can significantly reduce the error in the determination of low concentrations of elements. In addition to the consideration of these parameters, the method makes it possible to perform high-precision calibration of atomic emission spectrometers of the same type (produced in series), using not a set of several tens of approved standard samples, but only two standard samples. For each area, patent applications were formed and filed.
Anelaphus villosus (Fabricius) and A. parallelus (Newman) (Coleoptera: Cerambycidae) can be accurately distinguished using body measurements and DNA barcoding

Anelaphus villosus (Fabricius) and A. parallelus (Newman) are longhorned beetles (Coleoptera: Cerambycidae: Cerambycinae: Elaphidiini) that closely resemble each other in appearance. In practice, if antennomere 3 is distinctly longer than antennomere 4, the specimen is considered to be A. villosus, but the accuracy of this methodology is unknown. Authorities disagree about the ease of separating these two species based on morphological traits, and recent work hypothesises that they should be synonymised due to the difficulty of distinguishing them by either morphology or natural history. Assuming correct initial species determinations of curated specimens, as well as of those determined with DNA barcoding and by the primary author, data from 23 body measurements were collected from 50 A. villosus and 60 A. parallelus specimens. Stepwise discriminant analyses and discriminant functions were used to evaluate the ability to distinguish these species based on morphology. Species assignments from discriminant functions were very accurate and were supported by assignments determined with DNA barcoding. The ability to distinguish A. villosus and A. parallelus based on morphological and molecular differences provides evidence against the taxonomic hypothesis of synonymy under one species. A need for greater ecological understanding of these species remains.

Brown-McLean syndrome not reported in association with homocystinuria and generally occurs in patients with long-term aphakia. Presented as peripheral corneal edema with central clear cornea tends to spare vision without the need of any surgical intervention. The purpose of reporting such a rare condition as a first case of Brown-McLean syndrome associated with systemic disease of homocystinuria. Brown-McLean Syndrome in a patient with homocystinuria generally occurs in patients with long-term aphakia after different modalities of surgical intervention. A high clinical suspicion and regular follow-up is warranted for patients with systemic diseases who are aphakic or present with a subluxated lens for early intervention and better prognosis if needed.

This paper examines the delivery of oral health care and compares the delivery in 2020 with that before 1900. While equipment and materials have changed, the design of the office, and the use of personnel within the office has remained remarkably similar. The doctor is responsible for diagnosis and treatment with some support services provided by hygienists and assistants. This piece work delivery model contrasts with an assembly line model. The assembly line model is explored here in a hypothetical visit to a dental office in 2025. The paper describes the layout of practice as well as the role of the doctor and auxiliary personnel in the office.
