Informing the development of assistive technologies for persons with dementia by connecting financial measures of wealth to perceptions of task dependence
Authors: Czarnuch Stephen , Ricciardelli Rose , Mihailidis Alex
Published: July 2019

BACKGROUND:

Older adults with dementia have been targeted toward the development of assistive technologies intended to facilitate aging in place. Researchers have documented financial and occupation strain for the caregiver and the financial limitations experienced by persons with dementia. These factors constitute a potential hindrance to the use and applicability of assistive technologies; technologies that may reduce caregiver burden, allow more time for paid work, and, in consequence, reduce occupational strain.

OBJECTIVE:

To unpack how financial burden, operationalized as direct (e.g., income) and indirect (e.g., caregiver education, employment status) measures of wealth and assets, affect the perceived independence of people with dementia.

METHODS:

We draw on data collected through a cross-Canada survey of caregivers to develop a set of predictive models of care-recipient task independence.

RESULTS:

Our findings suggest that said measures of wealth can predict task independence, and more complicated or instrumental daily tasks (e.g., shopping, driving) are perceived as being those with which care recipients need most assistance.

CONCLUSIONS:

Considering the economical and emotional obstacles that affect both the caregiver and the care recipient, the development of assistive technologies that would be both financially realistic and assistive for this population in these instrumental daily tasks is warranted.

Authors: Mersil Sarah
Published: July 2019

Latar Belakang: Frictional keratosis didefinisikan sebagai plak putih dengan permukaan kasar dan berjumbai yang di identifikasi dari sumber iritasi mekanis yang biasanya akan sembuh jika sumber iritasi di hilangkan. Diagnosis banding dari frictional keratosis adalah leukoplakia karena gambaran klinisnya berupa plak putih yang menyerupai leukoplakia displastik. Laporan kasus : Seorang laki-laki 22 tahun datang ke klinik integrasi RSGM FKG UPDM (B) dengan keluhan terdapat putih-putih di kedua pipi bagian dalam. Dari pemeriksaan intraoral terlihat adanya plak papula putih tidak beraturan disertai eritema, berbatas tidak jelas dan tidak sakit pada mukosa bukal kiri dan kanan. Mengaku sering menggigit pipi bagian dalam dan juga memiliki kebiasaan merokok sehingga dapat dicurigai mengarah  frictional keratosis dengan diagnosis banding leukoplakia. Setelah dilakukan observasi lesi ini hilang sepenuhnya sehingga dapat didiagnosis frictional keratosis dan menyingkirkan kecurigaan terhadap leukoplakia. Kesimpulan: Gambaran klinis serta faktor-faktor predisposisi pada frictional keratosis hampir sama dengan leukoplakia, untuk itu dokter gigi harus lebih hati-hati dan mendetail dalam menghadapi kasus seperti ini.

Authors: Kurniati Novi
Published: July 2019

Latar Belakang: radiografi periapikal dua dimensi merupakan pemeriksaan yang sering dipergunakan untuk mengevaluasi hasil perawatan. Kelemahan inherent seperti superimposed, distorsi dan tidak dapat menampilkan lesi dari berbagai aspek membuat para dokter sulit untuk mendapatkan informasi yang sesuai keadaan yang sebenarnya karena keterbatasan radiograf dua dimensi. Pencitraan CBCT dapat menyediakan informasi yang relevan yang tidak ditemukan dalam radiografi periapikal.Laporan Kasus: pasien laki-laki berusia 38 tahun dengan keluhan utama gigi insisivus sentral rahang atas yang berubah warna karena trauma 10 tahun yang lalu. Pasien dirujuk untuk dilakukan radiografi periapikal, di mana tampak gambaran lesi radiolusen berbatas jelas di apikal disertai resorbsi internal gigi 11, dengan diagnosis granuloma periapical et causa nekrosis pulpa gigi 11. Setelah dilakukan perawatan 2 bulan dilakukan evaluasi I dengan radiografi CBCT, tampak tampak lesi radiolusen berbatas jelas dan tegas berukuran ±3,6 mm di apikal serta adanya perforasi sisi mesial akar gigi yang menyebabkan lesi radiolusen di sisi mesial gigi 11 disertai perforasi kortikal di tulang daerah palatal. Enam bulan kemudian dilakukan evaluasi II menggunakan radiografi periapikal dan CBCT. Pada radiografi periapikal tampak, lesi radiolusen berbatas jelas dan tidak tegas di apikal gigi. Pada radiografi CBCT tampak lesi radiolusen berbatas jelas yang telah mengecil di apikal, namun lesi di bagian mesial dan perforasi kortikal tulang palatal belum terjadi penyembuhan secara signifikan. Berdasarkan hasil radiografi CBCT, pasien di rujuk ke bagian Periodonti.Kesimpulan: pemeriksaan CBCT sangat diperlukan pada evaluasi perawatan kasus kompleks untuk mendapatkan informasi diagnostik yang lebih akurat.

Authors: Shah Chintan G , Buch Pankaj M
Published: July 2019

Introduction: Learning disability in children is an assorted group of disorders where the individual unpredictably fails to proficiently attain, regain, and use information. Objective: The objective of this study was to measure the prevalence of specific learning disabilities (SpLDs) such as dyslexia and dysgraphia among the Gujarati medium primary schoolchildren. Methods: A cross-sectional study was conducted in public schools of Gujarati medium among children aged 7–12 years from the second, third, and fourth standard. After obtaining a sociodemographic profile, a multilevel screening approach that begins with the identification of educational backwardness followed by exclusion of vision, hearing impairment, chronic health conditions, and subnormal intelligence was carried out among these children. In the last stage, remaining children were subjected to the National Institute of Mental Health and Neurosciences test for SpLDs. Results: The prevalence of SpLDs was 9.6% in sampled children, whereas 7.4%, 8.6%, and 7.1% had dyslexia, dysgraphia, and dyscalculia, respectively. Among children diagnosed with SpLD, 65.7% (n=25/38) of children had a combination of all three types of SpLDs. Conclusions: This study suggests that the prevalence of SpLDs in public schools is the same as private schools and metro center. We have used a multilevel screening approach that can be utilized for early identification of children with SpLD by Rashtriya Bal Swasthya Karyakram team without imposing load on specialist services. There is a need for sensitization of school teacher for timely referral, remediation strategies, and policy interventions to improve school performance and to reduce dropouts of schoolchildren.

Published: July 2019

Introduction: Pediatric surgery provides the opportunity to intervene positively in a wide array of diseases with potential lifelong impact. Objective: The objective of this study was to evaluate the significance of pediatric surgery under vast circumstances. Materials and Methods: All children in the age group of 0–10 years operated in a tertiary care hospital were analyzed. Grouping of cases was done using the International Statistical Classification of Diseases and Related Health Problems 10th Revision (International Classification of Diseases [ICD]-10)-WHO Version (2016) and incorporating terminology from the ICD-11 Beta Draft. Results: “Developmental anomalies” accounted for 79.1% of cases, while 20.9% were “acquired conditions requiring surgical intervention.” The common congenital malformations were those of the genital organs (17%), followed by those of the digestive (13%) and nervous system (13%), urinary system (12%), circulatory system (8%), and cleft lip and palate (7%). The essential surgery package for congenital anomalies should include expertise in repair of cleft lip and palate, anomalies of genital, digestive, nervous, urinary, and musculoskeletal system. Referral to superspecialty center is required only for “congenital malformations of the circulatory system.” Conclusion: Majority of the workload (79.1%) due to “developmental anomalies” points toward need for skills in correcting these, restoring anatomy for the proper growth, and physiological functioning. Inclusion of indirect inguinal hernia in the Chapter 20 ‘Developmental anomalies’ (ICD-11) will contribute to correct international comparisons and guide planning.

Published: July 2019

Los hechos acontecidos durante la Segunda Guerra Mundial, en donde se perdieron, destrozaron y robaron miles de obras artísticas, permitieron que la humanidad asuma la responsabilidad de cuidar el legado que había sido producido por nuestros antepasados. Es así que en los siguientes tratados y convenios, se les llamó «bien cultural» y buscaron su protección. La importancia de la creación de este bien radica en que en muchos países se presente una protección penal, con el fin de sancionar a los responsables de su deterioro. En el Perú sucede esto desde la promulgación del Código Penal de 1991, pero los estudios sobre estos delitos son escasos, tanto a nivel doctrinario como empíricos. Al tener Cajamarca el Monumento de Huacaloma, del cual es notorio su deterioro, en este artículo se presentará una breve revisión de la intervención penal. Se llega a establecer que resulta siendo insuficiente para frenar su destrucción. El artículo también deja notar que es necesario contar con autoridades competentes para evitar su completa destrucción.

TBILISI 1979 YEAR SYMPOSIUM ON THE UNCONSCIOUS – LOOKING BACK
Authors: Imedadze Irakli
Published: July 2019

In 1979 a large international symposium dedicated to the problem of unconscious was held in Tbilisi. More than 150 visitors from 17 foreign countries and about the same member from different scientific centers of the former Soviet Union took part in its work. These ciphers may not sound very impressive now but taking into account the years when the Soviet Union was still separated from outer world by the so called “iron curtain”, the symposium can indeed be considered a grand event. Foreign participants came not only from the countries of “socialist camp”, but also from Western states (Austria, Canada, England, Ireland, Italy, France, USA, Western Germany). One more notable thing is that a lot of researchers working in the sphere of psychoanalysis visited Tbilisi. Remembering the fact that psychoanalysis, even at that period, stayed as the main ideological “scarecrow” for “Soviet psychology”, the symposium seemed really unique and unprecedented.

Complex chalcogenides display semiconductor properties. In particular, heavy metal compounds that are formed in the Tl2Se-Sb2Se3 system are good thermoelectric materials. At the same time TlSbP2Se6 compound belongs to the family of hexaseleno-hypodiphosphates, which representatives have a number of interesting properties (optoelectric, non-linear, etc.) in the near infrared range. The combination of these properties in one material causes some scientific and practical interest, therefore our research was aimed to study the nature of the interaction between TlSbP2Se6 and the thermally stable phases of the Tl2Se-Sb2Se3 system in order to find new promising candidate for applications in electronic devices.

The alloys were prepared from corresponding binary, ternary compounds and quaternary TlSbP2Se6 by a direct one-temperature method in evacuated quartz ampoules at temperatures above the melting point of the initial and final products. The initial compounds were synthesized by the reaction of their high purity component elements in stoichiometric proportion.

According to the results of the research, it was found that cross-sections based on TlSbP2Se6 and the thermally stable compounds of the Tl2Se-Sb2Se3 section are quasibinary: Sb2Se3–TlSbP2Se6 and TlSbSe2–TlSbP2Se6. Tl9SbSe6 – TlSbP2Se6 and Tl2Se - TlSbP2Se6 systems are not quasibinary, instead quasibinary sections Tl2Se-Tl4P2Se6 and Tl9SbSe6-Tl4P2Se6 which crossing their.

The phase equilibrium in Sb2Se3 – TlSbP2Se6 and TlSbSe2 – TlSbP2Se6 systems were studied by common differential thermal analysis (DTA), X-ray powder diffraction (XRD) and microstructure analysis. The eutectic interactions are observed in both systems. The invariant points coordinates are: 77 mol.% TlSbP2Se6, 709 K (system Sb2Se3 – TlSbP2Se6) and 45 mol.% TISbSe2, 680 K (system TlSbSe2 – TlSbP2Se6). Significant boundary solid solutions are formed on the basis of the quaternary compound. Their region extends up to 10 mol% in the system Sb2Se3 – TlSbP2Se6 and to about 18 mol.% in the system TlSbSe2 –TlSbP2Se6 at annealing temperature (573 К). Near the Sb2Se3 and TlSbSe2, the solubility limits do not exceed several mol.%.
COMPOSITE MATERIALS BASED ON HYDROGEN DIOXIDE WITH CIRCONIA FOR THE DISPOSAL OF ANIONES Cr(VI) AND F(I) FROM WATER SOLUTIONS

Published: July 2019

The review is devoted to the problem of technogenic pollutionof awater environment bytoxic compounds, in particular, anionic compounds Cr(VI) and F(I), as well as technical and scientific ways to solve the problem. The sources of chromium and fluoride compounds entering the environment, their significance for the vital activity of living organisms, including the effect on human health, are considered.The content of chromium and fluorine compounds in various environmental objects was analyzed; special attention was paid to the concentration of these compounds in various water objects (rivers, seas, lakes, groundwater, drinking water, etc.). Fromexistingmethodsfor removing compounds of fluorine and chromium from aqueous solutions а reagent treatment, mutual neutralization, biological, ion exchange and membrane methodsare reviewed. The prospects of methods of electro-membrane technology are considered: electrodialysis, membrane electrolysis, as well as electrodeionization, which combines ion exchange and electrodialysis.The widespread use of these processes is restrained, first of all, by the low chemical and thermal stability of organic polymer membranes and their propensity to accumulate organic impurities. In addition, strongly acidic ion exchangers and membranes that are charge-selective do not exhibit selectivity with respect to certain ions. At the same time, for even better known inorganic membranes, even the charge selectivity is not inherent, which makes it difficult to use them in electromembrane separation processes. Inorganic membranes and granulated ion exchangers on the basis of selective oxide compounds characterized by sufficiently high chemical stability compared with polymeric materials, as well as the selectivity of the absorption of certain ions, are considered as promising for selective electromembrane extraction of anionic compounds Cr(VI) and F(I). It is shown that the perspective direction in the development of modern methods of separation and selective extraction of anions Cr(VI), F(I) is the development of composite selective membranes and ion exchange sorbents that combine the advantages of both a chemically stable inorganic matrix and selective ion exchangers based on the corresponding compounds.
PHYSICO-CHEMICAL PROPERTIES OF COMPOSITES ON THE BASE OF CERIA OBTAINED BY A CITRIC ACID METHOD

Published: July 2019

Composites with the formula nMOx–СеО2, where n is the mole part of copper or manganese oxide have been synthesized via citric acid aided route. Physico-chemical properties of materials obtained are investigated by XRD, low temperature desorption of nitrogen and by temperature-programmed reduction (TPR). It is defined that the composites with the n < 0.25 (for Cu) and < 0.75 (Mn) are the solid solutions obtained by the replacement of cerium ions in the structure of fluorite (СеО2) by copper or manganese ions. The existence of the separate phases of oxides such as CuO and Mn3O4 has been identified in the XRD patterns of composites with formula 0.25CuО–СеО2 and 0.75MnOx–СеО2. The parameters of cell and the particles size for all samples are calculated; decreasing these values occurs due to the solid solutions formation. Specific area of composites obtained is much bigger than specific area of individual oxides; the biggest values are determined for the samples containing the biggest part of copper or manganese oxide. According to TPR profiles of composites themaximal intensity of low temperature peak has the composite 0.25CuО–СеО2 that means the biggest part of the solid solution; so this material is the most active in CO and ethanol combustion. This fact can be explained by appearance of additional oxygen vacancies when ions Ce4+ are replacement by ions with the less oxidation state. The quantities of hydrogen used for reduction of samples with the copper oxide and samples with the manganese oxide with n < 0.5 are much bigger than the theoretical values; in this case the reduction of the part of ceria in the solid solution is happened. The composite 0.25MnOx–CeO2 is the most active in the ethanol combustion; full conversion to CO2 is finished at 205°С. The high activity of individual oxide MnOx and the composite 0.75MnOx–СеО2 in the reaction of toluene oxidation explains by the biggest part of Mn3+ ions in their structure among the all oxides investigated.

Identification and Frequency Dependence of Viscoelastic Parameters during Dynamic Creep Tests on Selected Pome Fruits
Authors: Farkas Csaba , Fenyvesi László , Petróczki Károly
Published: July 2019

In this paper, a novel control-loop concept is presented to investigate the viscoelastic properties of different pome fruits. Repeated mechanical effects are one of the most important risk factors during the postharvest procedures, so our work aimed to expand knowledge in the field. The actual investigations involved Golden Delicious apples and Packham pears. The developed model is based on the Poynting–Thomson body and, during the validating dynamic creep tests, different repeated compressive loads were applied. The examined frequencies were chosen from the most common components of the frequency distribution during the transportation process; the given range is responsible for the highest volume of fruit damage and the most extensive losses. The identified mathematical system determines the viscoelastic model parameters with the best fit to the measured creep data. The model properties of the tested fruit textures are compared in six different frequency setups, with the inspected pome species showing different elastic and viscous responses for the adjusted load conditions. The custom testing device with variable load functions and the proposed solution allow system identification with a wide range of setup possibilities. The resulted viscoelastic parameters can be used for further failure analysis and for the comparison of different pome fruit materials.
Bergamot (Citrus bergamia, Risso): The Effects of Cultivar and Harvest Date on Functional Properties of Juice and Cloudy Juice
Authors: Giuffrè Angelo
Published: July 2019

Reggio Calabria province (South Italy) is known for being almost the only area of cultivation of the bergamot fruit, grown principally for its essential oil, but today much studied for the health benefits of its juice. The biometrics and physico-chemical properties of the three (Citrus bergamia Risso) existing genotypes namely Castagnaro, Fantastico and Femminello were studied during fruit ripening from October to March. Castagnaro cultivar had the biggest and heaviest fruit during this harvest period. °Brix (7.9–10.0), pH (2.2–2.8) and formol number (1.47–2.37 mL NaOH 0.1 N/100 mL) were shown to be influenced by both the genotype and harvest date. Titratable acidity (34.98–59.50 g/L) and vitamin C (ascorbic acid) (341–867 g/L) decreased during fruit ripening. The evolution of flavonoids such as neoeriocitrin, naringin, neohesperidin, brutieridin and melitidin was studied both in bergamot juice and in the bergamot cloudy juice which is the aqueous extract of bergamot during fruit processing. Bergamot cloudy juice contained a higher quantity of flavonoids compared to the juice. This study gives important information regarding the cultivar and the harvest date for producers who want to obtain the highest juice quantity or the highest juice quality from the bergamot fruit.
De-electroadhesion of Flexible and Lightweight Materials: An Experimental Study

Published: July 2019

Electroadhesion (EA) is an emerging prehension method with wide application in robotics, including object handling, component assembly, and robotic locomotion. A major challenge with EA is the development of novel solutions for speeding up the release process, where residual charges inhibit release. In this work, a comprehensive study on the effects of EA base substrate and object material types on de-electroadhesion time is presented. Experimental results show that the de-electroadhesion speed is highly dependent on the base substrate and object material type. There is a strong inverse correlation between dielectric constant and de-electroadhesion rate, while a higher molecular weight demonstrates slower dielectric relaxation and hence release time. These findings will enable the design of cost-effective EA-based robotic end effectors with rapid release capabilities. EA grippers with quicker de-adhesion abilities could significantly improve the overall throughput of assembly lines where material pick-and-place tasks are involved. In addition, more efficient and faster locomotion speeds could be achieved for crawling or climbing robots where EA is employed as their active adhesion and de-adhesion feet.
