Introduction: Retention is necessary following orthodontic treatment to prevent relapse of the final occlusal outcome. So the aim of the study is to evaluate retention procedures and protocols which are used by the Orthodontists from Central India. Methodology: In this study a total of 128 Orthodontists practicing from Central India were sent questionnaire which consisted of questions regarding different types of conditions or orthodontic treatment and the choice of retainer they would prefer.the questions were so designed to know which retainer would they prefer among both the arch. Also to know which type of retainer (removable or fixed) they prefer for certain conditions. Result:A combination of fixed and removable retainers were commonly used by Orthodontists in both the dental arches, except after expansion of the upper arch when removable retainer was preferably used, and after the correction of rotation of mandibular anterior teeth where in Orthodontists chose fixed retainer over removable. Hawleys retainer was most preferred for upper arch (71.9%), Vaccum formed retainer for the lower arch (49.2%). In the fixed retainer bonded to all the anteriors was most preferred (76.6%) in the lower arch while bonded to Central Incisors in the upper arch (80.5%). Conclusion: The Hawley appliance was a predominant removable retainer. The bonded wire from canine to canine was the most frequent fixed retainer. Evidence-based guidelines are required for drawing a common retention protocol.

Background:Dentin bonding is an ever-evolving field in adhesive dentistry. With the introduction of newer systems into the market, there is a crucial need to test their efficiency in terms of bond strength. Dual-cured adhesives in theory may provide for a better degree of conversion as compared to conventional light-cured adhesives .Thus, the aim of this study was to compare the shear bond strength of three different self-etch adhesives namely ClearfilSE bond (Kuraray), Tetric N Bond Universal (IvoclarVivadent) and Futura Bond DC (Voco) to dentin. Materials & Methods: Ninety extracted non-carious, intact human mandibular molar teeth were selected for this study. Each tooth was decoronated using a double-sided diamond disc with water coolant to a depth of 2mm from the cusp tip .The cut dentin surface was then abraded against 600-grit wet silicon carbide papers for 60 seconds to produce a uniform smear layer. The root portion of each tooth was mounted on a plastic ring using cold cure acrylic resin. Specimens were then divided into three adhesive groups of 30 teeth each, Group A: ClearfilSE Bond (Kuraray), Group B: Tetric N Bond Universal (IvoclarVivadent), Group C :Futura Bond DC (Voco). All bonding agents were used according to the manufacturers’ instructions, in combination with the resin composite Tetric N Ceram (IvoclarVivadent). The samples were thermocycled, followed by shear bond strength testing using a Universal testing machine (Hounsfield). Data were subjected to statistical analysis using one-way analysis of variance (ANOVA) (P<0.05) and Post hoc Tukey’s test for inter- and intra- group analysis respectively. Results: Clearfil SE Bond yielded the highest shear bond strength values (30.9 ±4.66 MPa) which were statistically significant, followed byTetric N Bond Universal group (29.8 ±4.34) and the lowest shear bond strength values were recorded for Futura Bond DC (18.2 ±3.13). Conclusion: Clearfil SE bond and Tetric N bond Universal can be considered as better options than Futura Bond DC.

An attempt has been made in this paper to evaluate the psychological well-being of the dwellers of rehabilitation camps in Cooch Behar district, West Bengal, India, who have been sheltered after exchange of enclaves between India and Bangladesh and subsequent migration. Since people commonly migrate for their need, primarily for economic reason, their movement is basically oriented to economic well-being. But, in many cases, well-being may not be achieved through economic satisfaction rather migrants sometimes feel their lost world i.e. the place of living and its surroundings, which brings a psychological well being to them both positively and negatively. Results shows that rehabilitated people, although migrated as per their wish, have achieved economic satisfaction but psychologically a number of them are not happy and often remind their old memories.

Published: November 2020

In the entire gamut of publication and performance history, William Shakespeare is one of the most popular names and most of his plays have been acted and reacted, adapted and published in various forms. In many countries, to be particular, in India, perhaps due to the colonial heritage, Shakespeare has never ceased to fascinate – both in the pre- and post-independence era. Indian cinema has seen many versions of his plays in popular cinema. Amongst all the performances of Shakespeares plays, Vishal Bharadwaj movie Omkara (2006) may be considered as one of the best ever Indianized performances of his play Othello. This study is an attempt to critically study the recreation of Othello in the Indian setting in the light of the original play. It is aimed at capturing the universality in the works of Shakespeare to establish the acceptability of his creations in each age, the significance of his citation, and the purchase of his status in various cultural niches and registers. In the adaptation of Shakespeares plays in Indian films, the Bard is not only absorbed into the cultural fabric of India but still maintains a catalyzing presence in post-colonial India.

Authors: Zhang Bao , Li Zhi , Wang Yuanshao
Published: November 2020

In order to predict the fatigue life of frame, a new bench test method of the frame torsion fatigue is proposed, which can approximately reflect the results of enhanced road test. The frame finite element model was established and the simulation was carried out to determine the dangerous position of fatigue life failure. The load spectrum of the fatigue dangerous position was collected, and the fatigue damage value was analyzed by the rain-flow counting method and Miner criterion. The equivalent conversion relationship of the fatigue life between bench test and road test was established. The mean error between theoretical calculation result and bench test result is 5.2 %; The mean error between theoretical calculation result and road test result is 3.85 %. The results showed that the bench test method of frame torsion fatigue can improve the precision and reliability of the frame fatigue life prediction.
Experimental study on the shear stiffness and damping ratio of the coarse-grained soil against geogrid interface
Authors: Chen Aijun , Su Chunhui , Chen Junhua , Tang Xianyuan , Yuan Zhaoyao
Published: November 2020

Geosynthetic-reinforced soil structures are mostly used to retain subgrade slope of highway and railway. For the design and performance analyses of geosynthetic-reinforced soil structures under repeated loading, such as those induced by compaction, traffic and earthquakes, the understanding of cyclic soil–geosynthetic interface behaviour is of great interest. Nevertheless, experimental data concerning this type of behaviour are very scarce. A laboratory study was carried out and is described in this paper. This paper presents the behaviour of an interface between a coarse-grained soil and a geogrid under cyclic loading conditions. A large-scale direct shear test device able to perform displacement-controlled cyclic tests was used. The results obtained are presented and discussed, especially the effects of the displacement amplitude and normal stress on the shear stiffness and damping ratio are investigated. The dynamic response parameters of the soil-geosynthetic interface are greatly affected by the number of cycles, and the variations in the two parameters with the number of cycles are related to the normal stress and the shear displacement amplitude. when at large displacements, the damping ratio decreases first and then stabilizes with the number of cycles. However, at small displacement, the shear stiffness and damping ratio are all decrease somewhat at the initial stage of cyclic shearing. As the experimental materials used in this study are relatively single, and further experimental research should be carried out in the future. The shear parameters of interface in this study can provide reference for the design of reinforced soil structure.
Vehicle-bridge coupling dynamic response of a box bridge after reinforcement with prestressed CFRP
Authors: Cheng Xuansheng , Cai Xiangdong , Liu Bo , Zhang Wenting
Published: November 2020

The dynamic response of vehicle bridge coupling before and after strengthening with post-tensioned carbon fiber reinforced polymer (CFRP) is analyzed. To obtain a better dynamic response of vehicle bridge coupling, the theory of vehicle moving load is deduced and transformed. To obtain the dynamic response of the vehicle bridge coupling before and after the post-tensioned CFRP reinforcement, a numerical model of the vehicle bridge coupling before and after the post-tensioned CFRP reinforcement is established, and the vertical acceleration time history curve and vertical displacement time history curve of the 1/4, 1/2, and 3/4 sections of the side span and the middle span of the bridge before and after post-tensioned CFRP reinforcement are obtained under different speeds of heavy vehicles. The results show that with the increase in vehicle speed, the vertical displacement of the bridge has almost no change, but the increase in the vertical acceleration peak value is obvious, which results in a faster arrival of the vertical displacement and the vertical acceleration peak value and also causes the amplitude of the vertical acceleration of the bridge to increase greatly, and the vertical acceleration increase in the side span is significantly larger than that in the middle span. Post-tensioned CFRP can effectively reduce the vertical displacement and acceleration of the bridge, but there are some deficiencies in reducing the vertical displacement of the bridge. With the increase in speed, the effect of the post-tensioned method is better.
The seismically induced failure sequence of multiple components of high-speed railway bridges under different earthquake intensities

Published: November 2020

Though seismic vulnerability analysis of highway bridges is mature, there is little corresponding research on high-speed railway (HSR) bridges. The seismic vulnerability analysis of HSR bridges is very different to and more difficult than for highway bridges because the multiple components of the track structure are very complex. To fill this research gap, the authors establish a finite element (FE) model of an HSR bridge with the China railway track system II (CRTS II), which includes sliding layers, cement asphalt (CA) layers and fasteners, base plates, track plates and rails. Analytical results show that seismic responses of multiple bridge components have a linear correlation. Thus, the overall track-bridge system can be assumed to operate like a serial system. Here, the seismic response and vulnerability of various bridge components are first analyzed using the incremental dynamic analysis (IDA) method. Afterwards, the failure sequence is found by comparing the seismic vulnerability of critical bridge components. Finally, the seismic vulnerability of the overall track-bridge system is evaluated according to the upper and lower first-bounds. Results illustrate that the system vulnerability of HSR bridges, which is very different to that of highway bridges, is mainly determined by the sliding layers and fixed bearings. In particular, the serious damage of a sliding layer is caused by the uncoordinated deformation of beam ends, and fixed bearings may break down when they are exposed to strong earthquakes. The overall track-bridge system is prone to severe seismic damage when peak ground acceleration (PGA) is larger than 0.2 g.
Seismic responses of concrete rectangular liquid storage structure with large height-width ratio
Authors: Jing Wei , Xing Shangshang , Song Yu
Published: November 2020

Concrete rectangular liquid storage structure (CRLSS) with a large height-width ratio has good application prospects due to saving land resources. 3-D Solid element and 3-D Fluid element are used to simulate structure and liquid; and free surface is set to simulate the liquid sloshing behavior. Based on potential flow theory, a three-dimensional numerical model for CRLSS with large height-width ratio is established by ADINA. Results show that wall tensile stress exceeds the concrete tensile strength 2.39 MPa when liquid level height reaches to 11.70 m. There are the optimal baffle positions which can ensure that the wall tensile stress is less than the concrete tensile strength when PGA is 0.22 g, and the wall tensile stress reaches the minimum value when the baffle height is 3.6 m. Opening size has little effect on the wall tensile stress, but it has a significant effect on the baffle tensile stress. Seismic capacity of CRLSS with large height-width ratio designed by using the optimal baffle position can meet the requirements when PGA is 0.22 g, and it is necessary to carry out further comprehensive damping measures when PGA reaches 0.62 g. The arrangement of horizontal baffle can provide an effective way for the engineering application of large height-width ratio CRLSS.
Combined APSO-ANN and APSO-ANFIS models for prediction of pressure loss in air-water two-phase slug flow in a horizontal pipeline
Authors: Moghaddas Faezeh , Kabiri-Samani Abdorreza , Zekri Maryam , Azamathulla Hazi M.
Published: November 2020

Prediction of air-water two-phase flow frictional pressure loss in pressurized tunnels and pipelines is essentially in the design of proper hydraulic structures and pump systems. In the present study artificial neural networks (ANN) and adaptive neuro-fuzzy inference system (ANFIS) are employed to predict pressure loss in air-water two-phase slug flow. Adaptive particle swarm optimization (APSO) is also applied to optimize the results of the ANN and ANFIS models. To predict the pressure loss in two-phase flow, the frictional pressure loss coefficient needs to be determined with respect to the effective dimensionless parameters including two-phase flow Froude and Weber numbers and the air concentration. Laboratory test results are used to determine and validate the findings of this study. The performances of the ANN-APSO and ANFIS-APSO models are compared with those of the ANN and ANFIS models. Different comparison criteria are used to evaluate the performances of developed models, suggesting that all the models successfully determine the air-water two-phase slug flow pressure loss coefficient. However, the ANFIS-APSO performs better than other models. Good agreement is obtained between estimated and measured values, indicating that the APSO with a conjugated ANFIS model successfully estimates the air-water two-phase slug flow pressure loss coefficient as a complex hydraulic problem. Results suggest that the proposed models are more accurate compared to former empirical correlations in the literature.

Authors: Yuan Chengfu
Published: November 2020

In order to explore the regional water–salt balance mechanism in Hetao Irrigation District, field experiments were conducted in 2018 and 2019 in the Heji canal study area. The SWAP model was calibrated and validated based on field experiments' observed data. The SWAP model was used to simulate soil water–salt dynamics in saline wasteland after calibration and validation. The results showed that model simulation results of soil water content and soil salt concentration agreed well with the measured values. Soil water content and soil salt concentration changed obviously under the effect of farmland irrigation in the crop growing period. Soil salt was accumulated in saline wasteland. The soil salt accumulation of each soil layer in saline wasteland was 0.164, 0.092, −0.890 and −1.261 mg/cm3, respectively. Soil water content gradually increased and soil salt concentration gradually decreased in the autumn irrigation period. Soil salt was leached in the saline wasteland. The soil salt accumulation of each soil layer in the saline wasteland was −1.011, −1.242, −1.218 and −1.335 mg/cm3, respectively. The saline wasteland became a drainage and salt drainage region for cultivated land. The saline wastelands had an obvious role in adjusting salt balance and maintaining salt dynamic balance in Hetao Irrigation District.
Research on the schemes formulation and optimization method of sponge reconstruction in a highway service area
Authors: Peng Yu-hua , Li Zhuang , Ding Yong-shuai
Published: November 2020

This study proposed a method for constructing a low impact development (LID) plan to improve the utilization rate of rainwater in a highway service area and solve the problem of waterlogging. Firstly, based on the theory of LID, taking the total runoff as the control goal, and combining it with the functional zoning of the highway service area and the characteristics of LID facilities, several LID schemes were proposed. Then, the evaluation system of the LID scheme in service area was established by the analytic hierarchy process (AHP). These preliminary construction schemes were compared from three aspects (runoff control efficiency, economic efficiency and social efficiency) to determine the best LID plan. Finally, taking the Pu'er tunnel service area as an example, the construction scheme of the sponge city service area was optimized.

Use Characteristics and Triage Acuity of a Digital Symptom Checker in a Large Integrated Health System: Population-Based Descriptive Study
Authors: Morse Keith E , Ostberg Nicolai P , Jones Veena G , Chan Albert S
Published: November 2020

Background

Pressure on the US health care system has been increasing due to a combination of aging populations, rising health care expenditures, and most recently, the COVID-19 pandemic. Responses to this pressure are hindered in part by reliance on a limited supply of highly trained health care professionals, creating a need for scalable technological solutions. Digital symptom checkers are artificial intelligence–supported software tools that use a conversational “chatbot” format to support rapid diagnosis and consistent triage. The COVID-19 pandemic has brought new attention to these tools due to the need to avoid face-to-face contact and preserve urgent care capacity. However, evidence-based deployment of these chatbots requires an understanding of user demographics and associated triage recommendations generated by a large general population.

Objective

In this study, we evaluate the user demographics and levels of triage acuity provided by a symptom checker chatbot deployed in partnership with a large integrated health system in the United States.

Methods

This population-based descriptive study included all web-based symptom assessments completed on the website and patient portal of the Sutter Health system (24 hospitals in Northern California) from April 24, 2019, to February 1, 2020. User demographics were compared to relevant US Census population data.

A total of 26,646 symptom assessments were completed during the study period. Most assessments (17,816/26,646, 66.9%) were completed by female users. The mean user age was 34.3 years (SD 14.4 years), compared to a median age of 37.3 years of the general population. The most common initial symptom was abdominal pain (2060/26,646, 7.7%). A substantial number of assessments (12,357/26,646, 46.4%) were completed outside of typical physician office hours. Most users were advised to seek medical care on the same day (7299/26,646, 27.4%) or within 2-3 days (6301/26,646, 23.6%). Over a quarter of the assessments indicated a high degree of urgency (7723/26,646, 29.0%).

Conclusions

Users of the symptom checker chatbot were broadly representative of our patient population, although they skewed toward younger and female users. The triage recommendations were comparable to those of nurse-staffed telephone triage lines. Although the emergence of COVID-19 has increased the interest in remote medical assessment tools, it is important to take an evidence-based approach to their deployment.
ISO/IEEE 11073 Treadmill Interoperability Framework and its Test Method: Design and Implementation
Authors: Huang Zhi Yong , Wang Yujie , Wang Linling
Published: November 2020

Background

Regular physical activity is proven to help prevent and treat noncommunicable diseases such as heart disease, stroke, diabetes, and breast and colon cancer. The exercise data generated by health and fitness devices (eg, treadmill, exercise bike) are very important for health management service providers to develop personalized training programs. However, at present, there is little research on a unified interoperability framework in the health and fitness domain, and there are not many solutions; besides, the privatized treadmill data transmission scheme is not conducive to data integration and analysis.

Objective

This article will expand the IEEE 11073-PHD standard protocol family, develop standards for health and fitness device (using treadmill as an example) based on the latest version of the 11073-20601 optimized exchange protocol, and design protocol standards compliance testing process and inspection software, which can automatically detect whether the instantiated object of the treadmill meets the standard.

Methods

The study includes the following steps: (1) Map the data transmitted by the treadmill to the 11073-PHD objects; (2) Construct a programming language structure corresponding to the 11073-PHD application protocol data unit (APDU) to complete the coding and decoding part of the test software; and (3) Transmit the instantiated simulated treadmill data to the gateway test software through transmission control protocol for standard compliance testing.

Results

According to the characteristics of the treadmill, a data exchange framework conforming to 11073-PHD is constructed, and a corresponding testing framework is developed; a treadmill agent simulation is implemented, and the interoperability test is performed. Through the designed testing process, the corresponding testing software was developed to complete the standard compliance testing of the treadmill.

Conclusions

The extended research of IEEE 11073-PHD in the field of health and fitness provides a potential new idea for the data transmission framework of sports equipment such as treadmills, which may also provide some help for the development of sports health equipment interoperability standards.

Entre patriotas y polizones: polémicas letradas sobre los americanos en la prensa periódica (1810-1812)
Authors: Rosetti Mariana Inés
Published: November 2020

Las propuestas de la prensa hicieron uso en los años 1810-1812 del concepto de americanidad como una materia maleable desde la cual señalar injusticias y arbitrariedades. Para ello, los escritos públicos recurrieron a perspectivas en las que se construyeron aliados y enemigos y se utilizó el humor satírico como vía para suscitar la afinidad del lector. La flexibilidad del nombre americanos se utilizó como metáfora de la debilidad de autonomía política de las distintas provincias del continente americano. Nos interesa analizar al respecto algunas producciones de Juan López Cancelada que generaron respuestas vehementes del diputado de Tlaxcala en las Cortes de Cádiz, José María Guridi Alcocer, y de Servando Teresa de Mier. Estos tres pensadores hicieron uso de la prensa periódica para concretar o plantear soluciones políticas que los debates constitucionales erraban en contemplar o profundizar y lo hicieron recurriendo a los términos de patriotas y polizones.

Nowadays, the government is trying to improve the quality of the tourism sector in Indonesia. The government has built a lot of supporting facilities for tourists both local and foreign. However, the case of lost mountain climbers is still common. In this research, there will be a discussion about the sign system that provides people with information in Gunung Gede Pangrango Nationa Park. This study is also discussing a little about the natural conditions on some of these mountains.The study was conducted by direct observation of the climbing site to see and analyze directly the existing sign system. In addition, a number of statistical data will be collected from the management by means of a short interview which will be used as supporting data or secondary data in the study. This research is a qualitative study by conducting a literature study. This literature study was carried out during the sign system analysis process.Placement of signs, legibility and the durability of materials in extreme mountain weather conditions are the aspects to be analyzed based on the science of Visual Communication Design. This research was conducted so that the manager, both local and government, are able to give more attention to the application of the sign system along the climbing track so that it can help reduce the possibility of a climber getting lost.
KAJIAN REPRESENTASI MASKOT DKI JAKARTA "ELANG BONDOL" DALAM MEDIA (STUDI KASUS "MOMO" - ASIAN PARA GAMES 2018)
Authors: D Diean Arjuna , Muthi'ah Waridah
Published: November 2020

The Bondol eagle which has been clutching Salak Condet has been established as the Jakarta mascot since 1989. Unfortunately, this fact is not widely known by the public. In fact, most people assume that capital mascot is other icons that are far more popular, such as Monas and Ondel-Ondel. Apart from being caused by the decline in the flora and fauna resistance because the area is affected by development, one reason for the low popularity of the two mascots is the lack of representation of both of them in objects that are closely related to people's daily lives. This mascot was once the TransJakarta logo and is often present in batik motifs and posters, but is now rarely found. The latest application of this mascot actually comes in the form of Momo, the 2018 Asian Para Games mascot. Although it is not a special event held by the local government, in that representation, the Bondol eagle comes with the identity of Jakarta as one of the organizing cities. This research attempts to examine this phenomenon from the perspective of semiotics. The research is devoted to the representation of the Bondol eagle in various graphic media and visual communication related to the 2018 Asian Para Games, using descriptive-analytical methods. It is hoped that this research can become one of the references in the discussion and development of the Jakarta mascot in the media. The study was conducted with a descriptive qualitative method with a semiotics and shape morphology approach.

Published: November 2020

Os Centros de Especialidades Odontológicas foram implantados com o intuito de atender a população com procedimentos odontológicos de média complexidade que não eram realizados na atenção básica. Oferecem serviços especializados de diagnostico bucal, endodontia, cirurgia oral menor, periodontia avançada e tratamentos básicos para pacientes especiais. Na área de endodontia realizam obturação de canal radicular, retratamento de canal e selamento de perfuração radicular. O Ministério da Saúde instituiu metas mínimas de produção mensal por especialidade e por tipo de CEO para monitorar a produtividade e realizar a gestão do repasse. Este estudo tem como objetivo analisar a produção ambulatorial dos CEO localizados na Bahia no ano de 2016, quanto aos procedimentos endodônticos e avaliar o cumprimento de metas relacionadas a especialidade de endodontia. Para isto foi realizado um estudo do tipo quantitativo-descritivo utilizando dados secundários obtidos através do Sistema de Informação Ambulatorial do Sistema Único de Saúde, do Cadastro Nacional de Estabelecimentos de Saúde e da Secretaria Estadual de Saúde da Bahia. No ano de 2016 foram realizados um total de 26.599 procedimentos endodônticos nos CEO da Bahia, os procedimentos mais realizados foram: obturações de dentes permanentes uni-radiculares (36,4%) e obturações de dentes permanentes bi-radiculares (29,8%). Dos 71 CEOs existentes neste período, 84,5% não cumpriram as metas estipuladas para a especialidade de endodontia. O não cumprimento pode estar relacionado a outros fatores que não foram avaliados neste estudo.
