Authors: Mohd Suan Mohd Azri , Mohammed Noor Syahireen , Chan Huan Keat , Soon Hooi Imm , Khasim Sharihan
Published: December 2020

Dental malocclusion can affect the psychological and social aspects of adolescents. However, the knowledge of this condition has been limited in the Malaysian population. This study aims to explore the psychosocial impacts of dental malocclusion among adolescents in Kedah state, Malaysia. A qualitative study was conducted at two public specialized dental clinics. Focus group discussion (FGD) and in-depth interview (IDI) were conducted among adolescents aged between 11 and 19 years, who received orthodontic treatment for moderate to severe dental malocclusion. All the FGD and IDI sessions were video-recorded, transcribed verbatim, and translated into English. The thematic analysis method was used for the data analysis. A total of 32 adolescents participated in six sessions of FGD and five sessions of IDI. Four themes emerged from the data analysis: (i) pressure to seek treatment, (ii) negative feelings about one’s dentofacial image, (iii) negative influences on interpersonal relationship, and (iv) negative impacts on school performance. The findings indicate that adolescents with dental malocclusion had been receiving pressure from different parties and generally had low self-esteem, which eventually affected their relationship with family and friends and their involvement in school activities. Therefore, public education and interdisciplinary collaboration to address their psychosocial needs are required.

Authors: Mutiarin Dyah , Tomaro Queenie Pearl V. , Almarez David N. , Haictin Ken M. , Sakir
Published: December 2020

Surveys and polls in the Philippines reveal that there is wide support for President Duterte’s Drug War. This study investigates why Filipinos support President Duterte’s Drug War Strategy. This paper advances the Theory of Planned Behavior by testing the extent to which Attitude, Subjective Norm, and Perceived Behavioral Control affect the intention of a young Filipino to support the Drug War strategy. A self-reported questionnaire survey was conducted to 197 Filipinos enrolled in four universities in Cebu City, Philippines. Linear Regression analysis and Structural Equation Modelling were employed in analyzing the gathered data with the aid of SPSS and Smart PLS. The results of the study reveal that Attitude and Perceived Behavioral Control are the main factors behind the youth’s support to President Duterte’s Drug War. This implies that strategic intervention in transforming people’s attitudes and facilitating the ease in showing support to the activities linked to the drug war are key foci to sustain if not increase, people’s support to the drug war policy.
Scandal and Malay Politics: A Question of Dignity Against Anwar Ibrahim and Azmin Ali
Authors: Mohamad Shukri Syaza Farhana
Published: December 2020

Political scandal has become very common in a democratic country as political rivals bid to discredit one another. An open and free media allows politicians from different sides to publicize alleged wrongdoings by their opponents. There are different scandals ranging from financial, political to moral scandals. Using dignity as a framework, this paper argues that moral or sex scandals are most effective to defeat a Malay politician in Malaysia because a section of the Malay population looks upon virtuous conduct to evaluate the capability of a leader. Specifically, this paper uses homosexual accusations against Anwar Ibrahim and Azmin Ali to show that this is the type of scandal that is convenient to bring into question their dignity. The paper concludes that after the same tactic is used over the decades, it appears that voters are reaching a saturation point, especially among middle-class Malays.
Solid Waste Management in Urban and Rural Communities of Santa Cruz Watershed, Laguna, Philippines
Authors: Nguyen Miriam Ramirez , Tan Maria Francesca Ofren
Published: December 2020

Solid waste management (SWM) has become a continuing hurdle for governments and communities because of its multi-faceted nature. With the worsening SWM problem, the Philippines enacted Republic Act 9003, the Ecological Solid Waste Management (SWM) Act 2000, instituting SWM Program. Water quality in water bodies and watersheds is adversely affected by pollution, exacerbated by increasing population and urbanization. This study examined RA 9003 implementation in urban and rural communities of Santa Cruz Watershed (SCW) which drains into Laguna Lake. Knowledge, awareness, and perceptions (KAPs) of communities were elicited using focused group discussions, interviews, and surveys in barangays within the watershed. Municipalities have completed respective10- year SWM Plans, organized SWM Boards, and SWM committees in villages. Communities showed satisfaction with SWM implementation and monitoring but rural communities had higher overall SWM effectiveness ratings. Both communities were willing to pay for a cleaner environment. Challenges that hamper better implementation of RA 9003 include non-segregation of solid waste by residents attributed to lack of awareness and discipline; irregular garbage collection; inadequate garbage trucks; lack of functional materials recovery facilities; and limited government resources. Addressing these concerns will further boost RA 9003 compliance and enhance the effectiveness of implementation and monitoring in the communities.
Examining Duffy’s Textual Space in “Water” and “Cold” through the Unnatural Ecopoetics Concept
Authors: Mhana Zainab Abdulkadhim , Talif Rosli , Zainal Zainor Izat , Singh Hardev Kaur Jujar
Published: December 2020

Unnatural ecopoetics presents new directions for poetry scholars. It is a theoretical lens that studies how texts use self-reflexive language and formal experimentation to create a textual space where material and nonmaterial environmental elements are uncovered. The term material stands for all physical objects and places, whether man-made or occurring naturally in the world. Nonmaterial, on the other hand, refers to the invisible emotional, historical, political, and personal elements that influence the speaker’s experience of space and the translation of it to the textual space of a poem. Post-modernist poet Carol Ann Duffy has played a pivotal role in contemporary English poetry. While many studies have dealt with her poetry, few have examined Duffy’s poetry in light of the unnatural ecopoetics concept. In this paper, the reader is invited to read within the textual space of Duffy’s “Water” and “Cold” (2011) through the lens of unnatural ecopoetics. This article argues that Duffy’s experience and memories of her mother’s last days configured nonmaterial elements fused with material elements of her environment. The findings of this study provide a new way of analysing contemporary poetry through ecopoetics reading by delving into literary texts and examining all the environmental elements and situations around a persona in a poem or the poet.
Quality Predictors and Clinician Performance in Using Health Information Systems: A Test of Mediating Effect
Authors: Salleh Mohd Idzwan Mohd , Abdullah Rosni , Zakaria Nasriah
Published: December 2020

Medical errors are prevalent barriers that negatively affect clinicians’ productivity when using a health information system (HIS). In Malaysia, medication errors have critically increased in the past few years and this phenomenon requires immediate academic and managerial attention. This study aimed to determine whether the effective use of HIS could predict the effects of the system, records, service, and knowledge qualities on the performance of clinicians. A total of 1200 surveys were administered to clinicians in different health institutions with HISs. The mediation effects based on 817 usable data were analyzed using partial least squares (PLS). In the path model, results demonstrated that effective use had a positive effect on the outcome variable and partially mediated the positive effects of quality predictors towards enhanced user performance. In other words, effective use of HISs increased the performance of clinicians through the ease of system functions and features, well-organized contents, and minimal data entry errors in EHRs, onsite technical support, and efficiency of drug order entry and decision support tools usage. Future evaluation studies of HIS should integrate effective use, and hospitals must strongly consider this predictor for the system upgrade or new implementation to avert medical errors when the use of the system is compulsory.

LOAD BALANCING PROTOCOL FOR ENERGY ACCOMPLISHED ROUTING IN WSN
Authors: VIVEKANAND MANA , REDDY SUMA
Published: December 2020

Wireless sensor networks (WSNs) have been considered as a promising method for reliably monitoring both civil and military environments under hazardous or dangerous conditions. Due to such environments ,the power supplies for sensors in the network are not usually rechargeable or replaceable. Therefore, the energy efficiency is critical for the lifetime and cost of WSN. Numerous mechanisms have been proposed to reduce the impact of communication protocols on the overall energy dissipation of WSN and communicating it with other nodes, moving on to the sink via transceiver. Efficiency of protocol can only be beneficial if the network is alive otherwise what to do for the novel ideas with the dead network. In this paper, Our proposed cluster based routing algorithm has exploited threshold level based load balancing and role transfer techniques along with multi-assistant cluster heads to cope with the aforementioned power hungry issues. Combination of multi hop and direct routing has improved our protocol energy utilization.

Authors: D. BAWANKAR SHYAM , B. BHOPLE SONAL , D. JAISWAL VISHAL
Published: December 2020

Large-scale networks of wireless sensors are becoming an active topic of research.. We review the key elements of the emergent technology of “Smart Dust” and outline the research challenges they present to the mobile networking and systems community, which must provide coherent connectivity to large numbers of mobile network nodes co-located within a small volume. Smart Dust sensor networks – consisting of cubic millimeter scale sensor nodes capable of limited computation, sensing, and passive optical communication with a base station – are envisioned to fulfil complex large scale monitoring tasks in a wide variety of application areas. RFID technology can realize “smart-dust” applications for the sensor network community. RFID sensor networks (RSNs), which consist of RFID readers and RFID sensor nodes (WISPs), extend RFID to include sensing and bring the advantages of small, inexpensive and long-lived RFID tags to wireless sensor networks. In many potential Smart Dust applications such as object detection and tracking, fine-grained node localization plays a key role.

Authors: K. WAGHDHARE LIKHITA , NAGRARE T. H.
Published: December 2020

Vehicular Ad hoc network(VANET) are special type of Mobile Adhoc Networks(MANET) where wireless equipped vehicles from a network are continuously travelling along the road. Node movement feature of Vehicular ad hoc network (VANET) closely resembles with that of mobile ad hoc network (MANET) but its high speed mobility and unpredictable movement characteristics are the key contrasting feature from that of MANET. The similarity nature suggests that the prevailing routing protocol of MANET is very much applicable to VANET. However, on the same line, the dissimilarity characteristics result in frequent loss of connectivity. In VANET, topology changes rapidly and there is frequent disconnection which makes it difficult to design an efficient routing protocol for routing data among vehicles called vehicle to vehicle communication. Many routing protocols where implemented like AODV, AOMDV, SD-AOMDV, DSDV, CBDRP. SD-AOMDV adds the speed and direction as two mobility parameter. By enhancing the performance of SDAOMDV routing protocol, packet delivery ratio, and throughput can be increased and end-to-end delay can be reduce.

Twitter Hesaplarının Post-Truth İçeriklerle İslamofobi Aracına Dönüştürülmesi: Geert Wilders Örneği
Authors: KUTLU Mahmut
Published: December 2020

İslamofobi söylemi, kısaca İslam dinî ve onun temsilcileri olan Müslümanlara karşı duyulan korku ve nefret olarak adlandırılmaktadır. Bu korku ve nefretin kökeni yüzyıllar öncesine kadar dayandırılsa da 11 Eylül 2001 New York olaylarından sonra hızlandığı görülmektedir. Amerika ve Avrupa ülkelerinde İslam dinine karşı yapılan küçümseyici propagandalar, hakaret içerikli yazılar ve karikatürlerle bu korku ve nefret tüm dünyada uyandırılmaya çalışılmaktadır. İslamofobiyi yayma aracı olarak da hem ucuz hem kolay hem de mesajı yaymada en hızlı araç olan sosyal medya hesapları kullanılmaktadır. Hemen hemen herkesin kullanabildiği ve milyonlarca kişinin çevrim içi olduğu bu sanal mecralarda İslam dinini ve onun Peygamberi olan Hz. Muhammed’i (sav) çirkin ve kötü göstermeye çalışan paylaşımların sayısı hayli fazladır. Bu araştırmada Geert Wilders isimli politikacının Twitter hesabı göstergebilimsel yöntemle incelenmiştir. Siyaset adı altında, korku ve nefret söyleminin bütünleştirildiği bu Twitter hesabında, sürekli İslam dinini küçümseyen paylaşımlar yapılmaktadır. Sosyal medya üzerinden İslamofobinin nasıl yayıldığını araştırıp ortaya koyması bakımından çalışma önem arz etmektedir.
Makinizm Çağında Dinsellik
Authors: ÇUHADAR Mustafa
Published: December 2020

Teknoloji ve dinsellik arasındaki ilişki, günümüzde medya ve din etkileşiminin incelenmesi gereken bir alanını oluşturmaktadır. Bu çalışmanın konusu, teknoloji-dinsellik arasındaki etkileşimin bilhassa iletişim teknolojileriyle evrilme biçimleridir. Çalışma böylelikle teknolojik ve dinsel pratiklerin bir kavramsallaştırmayla tanımlamasını amaçlamaktadır. Çalışmanın problemi geleneksel dini pratiklerin, teknoloji tabanlı dinsel-manevi pratiklere dönüşümüdür. Bu problem temel alınarak İranlı sosyolog Dr. Ali Şeriati’nin (1933-1975) “makinizm” kavramından hareketle, dinsel pratiklerin makinelerle birlikte nasıl evrildiği, çeşitli örnekler üzerinden betimleyici bir tarzda sunulacaktır. Teknoloji ile dinsellik arasındaki ilişkiyi, farklı formlarıyla ortaya koymak bu çalışmayı farklı kılan unsur olarak değerlendirilmektedir.

Çalışma esnasında sanal mezarlık, dijital mezar taşları, dinsel matik olarak adlandırdığımız hatim matik, esans matik gibi iletişim teknolojilerini de içerecek şekilde tasarlanan teknolojik-dinsel pratikler incelenmektedir. Mezkûr uygulamalar, bu çalışmanın sınırlarını da oluşturmaktadır. Bu yönüyle çalışma bir kavrama yüklenen anlamın insan makine ilişkisinde nasıl tezahür ettiğine ilişkin örneklerin ele alındığı betimleyici bir araştırma olma hüviyetine sahiptir. Çalışmanın nihayetinde, dinsel bazı pratiklerin, iletişim teknolojilerine ve makinelere de uyarlandığı, bu uyarlamanın farklı din ve geleneklerde de görüldüğü, bunun neticesinde, geleneksel doğalarından farklı biçimlere de evrildiği ve böylelikle de “dinsel makinizm” kavramının teknolojik-dinsel pratikleri inceleme açısından elverişli bir nosyon olduğu sonucuna ulaşılmıştır.

Published: December 2020

Günümüz temel bilgi kaynaklarından olan kitle iletişim araçları aynı zamanda ötekinin kurgulandığı, ideolojik amaçlarla nefret söyleminin inşa edildiği ve algı yönetiminin yapıldığı bir zemin olma özelliği taşımaktadır. Bu durumun somut izlerini medyanın İslam ve Müslümanlar ile ilgili içeriklerinde gözlemlemek mümkündür. Tarihsel bir oryantalist ön yargı taşıyan, ayrımcılığı ve yabancı düşmanlığını sürdüren Batı medyası, üretmiş olduğu içeriklerle İslamofobik tutum ve eylemlerin artış göstermesine sebep olabilmektedir. Bu çalışmada da Avrupa medyası örneğinde, medyanın İslam ve Müslümanlar ile ilgili oluşturmuş olduğu içerikler incelenmiştir. İslamofobinin medyatik üretimine ilişkin bir sorgulamayı içeren ve 16 Avrupa ülkesindeki farklı medya türlerinde yer alan güncel meselelerde İslam’ın ve Müslümanların temsil/sunum şeklini sorgulayan çalışmada nitel yönelimli içerik analizi yöntemi kullanılmıştır. Araştırma sonucunda, Avrupa’daki birçok yazılı ve görsel medyada, İslam ve Müslümanlara yönelik tarihsel süreçten beslenen negatif bir ton taşıyan ve İslam karşıtlığı içeren ifadelerin/anlatımların/kurguların sıkça yer aldığı belirlenmiştir.

Yerba mate is a Brazilian native species; its importance is due to cultural, environment, and economic factors. Species seedlings production needs to be improved, evaluating alternative substrates and containers. Therefore, we evaluated growth and quality of yerba mate seedlings produced on organic waste-based substrates in biodegradable and non-biodegradable containers. Commercial substrates based on pine bark (CS) and components based on sewage sludge (SS) and coal residue (granulometry from 1 to 3 mm - CR) were used. For each container, were prepared treatments with different substrate components: 75CS/25CR, 50CS/50CR, 25CS/75CR, 75CS/25SS, 50CS/50SS, 25CS/75SS, and CS. Substrates were submitted to physical and chemical analysis. The containers used were 110 cm³ polypropylene tubes, 500 cm³ polyethylene plastic bags, 460 cm³ paperpot®, and 460 cm³ TNT (non-woven fabric). Total height, stem diameter, shoot, and root dry biomass at the end of the seedlings production period were measured and total dry mass, Dickson quality index and height/diameter ratio were calculated. All containers used with commercial substrate provided satisfactory seedlings growth. The substrates showed distinct physical and chemical characteristics due to the addition of sewage sludge and coal residue, which resulted in higher pH and lower seedlings growth. Physical and chemical characteristics of substrates influenced growth and quality of yerba mate seedlings and the alternative substrates used in this study are not suitable to produce seedlings of the species on these conditions. The containers did not influence the variables used in this study.

The plant interaction knowledge can be applied in several sectors in agriculture such as crop rotation, weed management, green manure and the use of cover crops. Studies on the allelopathic potential of certain plants have been carried out with the application of vegetable extracts on the seeds of a sensitive plant, however, a consensus has not been reached regarding the best way to prepare such extracts. This study aimed to evaluate the efficacy of methods of extraction of allelopathic compounds and the bioactivity of different concentrations of the Mentha spicata L. aqueous extract on Raphanus sativus L. seeds. A completely randomized design was used in a 5x4 factorial scheme with four replications and four extraction methods (infusion, grinding in a blender, drying at 40 °C and 70 °C) and five concentrations (0; 25; 50; 75 and 100%). The variables investigated were: phenolic compounds quantification, germination, germination speed index (GSI), mean germination time (MGT), radish shoot and root length. The extract presenting the highest amount of phenolic compounds was prepared via infusion (724.36 µg/mL), followed by drying at 40 °C (605.07 µg/mL), blending (594.12 µg/mL) and drying at 70 °C (529.36 µg/mL). The Mentha spicata L. aqueous extracts interfered in the radish seed physiological quality, by inhibiting germination, GSI and MGT increase, mainly when in higher concentrations. There was a directly proportional relation between the quantity of phenolic compounds extracted through different extraction methods and the interference in the physiological quality of the radish seeds.

A horticultura demanda alta produtividade, necessitando de qualidade e uniformidade inicial de suas mudas com implicação direta desde o seu desenvolvimento até o plantio definitivo. Entre as espécies hortícolas, destaca-se a couve-flor que apresenta forma e sabor característico, sendo muito consumida no país o ano inteiro. Assim, o objetivo deste trabalho foi avaliar a emergência de plântulas e a produção de mudas de couve-flor em diferentes substratos e regime de irrigação. O experimento foi conduzido na estufa, em delineamento inteiramente casualizado, organizado em esquema fatorial 7x3 (sete composições de substratos:  nas proporções volumétricas de 1:0:0; 0:1:0; 0:0:1; 1:1:1; 1:1:0; 1:0:1 e 0:1:1, com os substrato comercial Carolina Soil®, casca de arroz carbonizada e areia, respectivamente) e (três regimes de irrigações: 1; 2 e 3 vezes por dia, por trinta minutos cada, em sistema Deep Film Technique), com quatro repetições, sendo cada unidade experimental composta por oito sementes/plântulas. A semeadura ocorreu em bandejas plásticas alveoladas de 204 alvéolos, com irrigação diária nos regimes hídricos supracitados. As contagens das plântulas emergidas ocorreram diariamente até aos 21 dias após a semeadura (DAS). Avaliaram-se, nesta ocasião, o índice de velocidade, o tempo médio, a velocidade média e a frequência de emergência, aos 37 DAS, foram avaliados a altura da parte aérea, o comprimento radicular, o número de folhas e a estabilidade do torrão. Verificou-se que a interação entre as composições de substratos e os regimes de irrigação promoveram boas condições para a emergência de plântulas, bem como para a formação de mudas de couve-flor. Recomendando-se as composições de substratos 1:0:0 e 1:1:0, entre duas a três irrigações de trinta minutos cada, em sistema Deep Film Technique.

Objetivo: avaliar o impacto da colaboração internacional na visibilidade da produção científica indexada na Web of Science do Programa de Pós-Graduação em Ciências Biológicas: Bioquímica, da Universidade Federal do Rio Grande do Sul, de 2007 a 2016.Método: A partir de técnicas bibliométricas (produção, coautoria e visibilidade), avaliaram-se duas questões centrais na política de internacionalização do Sistema de Avaliação da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES): 1) o conjunto de docentes atende aos atributos qualitativos de internacionalização quanto à publicação com pesquisadores estrangeiros? 2) as publicações com coautoria internacional estão relacionadas com os estratos mais elevados do Qualis Periódicos?Resultado: O aumento da rede de cooperação com diversos países demostra que foi atingida a dimensão internacional da produção científica dos docentes do Programa, seguindo a atual tendência da ciência brasileira. Em 20,8% da produção com coautoria internacional, foram identificadas assimetrias internas: a maioria dos docentes apresentou de uma a cinco ou nenhuma publicação com cooperação de pesquisadores estrangeiros, enquanto que poucos docentes produziram mais de seis publicações individuais. A política de internacionalização é uma estratégia eficaz de difusão científica: as publicações em periódicos classificados nos estratos mais elevados do Qualis têm coautoria internacional.Conclusões: Os resultados apontam para a necessidade de estratégias institucionais e governamentais para minimizar as assimetrias existentes de produção científica entre os docentes com o fomento e estímulo à internacionalização
“Um jeito negro de ser e viver”: (re) inventando a vida no contexto da pandemia da covid-19 – o que dizem as crianças negras e suas mães

Published: December 2020

O  artigo tem como objetivo analisar como  a vida das crianças negras de um Centro Municipal de Educação (CMEI) em Salvador - e de suas mães - tem sido (re) inventadas  no contexto da pandemia da Covid-19.  Para tanto, discute-se o racismo, elemento estruturante da sociedade, documentas legais que amparam as crianças e as infâncias destacando o direito à vida e a educação, fazendo um contraponto com as narrativas dos sujeitos da pesquisa. Do ponto de vista teórico-metodológico é uma abordagem qualitativa de cunho exploratório, respaldada por Rosemberg (1996), Cavalleiro (2003), Dias (2007), Abramovicz (2016), Nunes (2016),   Franco; Ferreira (2017),  entre outros. Os resultados encontrados apontam que o pertencimento étnico-racial e as condições materiais de existência organizam a vida dos sujeitos da pesquisa. Conclui-se que as crianças negras e suas mães têm um “jeito negro de ser e viver” (MAKOTA VALDINA, 2005), ancorado nos valores civilizatórios afro-brasileiros (TRINDADE, 2010), e que isso impacta na forma como elas (re) inventam a vida, construindo estratégias individuais e/ou coletivas para ser/estar no mundo.
3D Data Analysis for Teeth Morphology Study
Authors: Gaboutchian Armen , Knyaz Vladimir , Vasilyev Sergey , Maksimov Anatoly
Published: December 2020

Morphological studies are carried out predominantly in dental or anthropological research not just because these disciplines are directly related to teeth: dental structures are able to provide a wide-range of important information. Traditional odontological (related to teeth) study techniques can be associated, in general, to descriptive and measuring approaches. Descriptive techniques have been always more developed and compensating scarceness of odontometrics, as traditional manual measurements provide definitely insufficient information for morphological assessments – only approximate size evaluations are possi- ble. However, the presented in the article new non-contact odontometric technique has proved its capability to overcome barriers and to improve dental measuring research through obtaining dense and accurate data of significant diversity and amount to turn quantitative assessments of dental structures into qualitative and related to morphology. The method itself is based on improved interpretation of dental morphology providing two basic stages: orientation of 3D models of teeth and measurements on series of its sections. At the final stage odontometric data is captured, re-calculated and subjected to analyses.

Glands segmentation is a very important and yet challenging problem of histological images analysis. Accurate segmentation of mucous glands is a crucial step to obtain reliable morphological statistics and is necessary for the development of high-quality diagnostic algorithms, which are an integral part of timely medical care. In this paper we propose a two-stage segmentation method, which predicts the probability maps of glands boundaries in histological images based on a priori knowledge about the geometric shape of the mucous glands and uses a convolutional neural network (CNN) model to get the final segmentation result based on the predicted probability maps. The proposed method demonstrates good results in separating adjacent glands, which is one of the most challenging aspects in automatic segmentation of histological glands and one of the most complicated for algorithms based on applying convolutional neural networks. The evaluation of the proposed algorithm was performed with Warwick-QU dataset, which contains real histological images of colon tissue.

The integration of information technologies in healthcare practice significantly changes the methods of diagnosis and treatment, the forms of interaction of doctors with patients and colleagues, the organization of treatment and recovery of health. The field of reconstruction of the auricle is still a huge challenge for facial plastic surgeons and requires at various techniques to find the best treatment for each patient. The paper describes the application of computer modeling and laser stereolithography technology in surgical practice for auricular surfaces ectoprosthetics. To improve the accuracy and quality of the surgical intervention the positioning of external prosthesis is applied with the aid of personal templates and computer navigation. The accuracy of ectoprosthesis positioning when using a plastic mask template was 0.3-0.4 mm, while computer navigation was 0.1 - 0.2 mm. Using personalized templates is a simpler and more intuitive way of positioning that does not require expensive computer navigation systems. This example of ectoprosthetics shows the possibilities of various reconstructions of facial organs, not only the ear, but also, for example, the nose, using computer modeling and 3d printing technologies
Caustics, Orthotomics, and Reflecting Curve with Source at an Infinity
Authors: Dvoretskii Aleksandr
Published: December 2020

The properties of the first reflection of curves can be investigated by their connections. It is giving us the possibility to construct new reflecting curves and reflecting systems with the demand properties. The studied reflective properties of plane curves as sections of reflecting surfaces are preserved if these sections are generators of surfaces of revolution and rotative surfaces (the normal to the section at a given point coincides with the normal to the surface at the same point) and the source of the incident rays is in the same plane section. Caustics, orthotomics, and reflective curves with a source at an infinity are considered. For a given orthotomics, there is a one-parameter set of reflective curves with a source at an infinity. To select one reflecting curve from this set it is necessary to put straight line, perpendicular to the direction of the incident rays. The shaping of a reflecting curve and its caustics according to its given orthotomics, as well as the shaping of orthotomics according to a given reflective curve with a source at an infinity, is studied, and algorithms for these shaping are proposed. Equations are written for all studied curves. Caustics, orthotomics, and reflective curves with a source at infinity are a promising means of using the methods of geometric optics for modeling natural objects in ergo design.

Published: December 2020

Features of using the regression test selection method for automated testing of the graphical user interface in the development of information systems that consist of a set of modules are considered. The source of the need to create additional test environments required in the development of multi-module information systems that are using databases is specified. The three most popular approaches to organizing test environments – Copying, Scaling, and Scaling with synthetic data generation – are considered. The positive and negative sides are considered in terms of implementation, using, and resources spent on creating and maintaining resources, as well as in terms of the reliability of the results obtained in the process of testing models created using these approaches. The positive aspects of checking the quality of complex multi-module information systems from the point of view of the graphical user interface by various testing methods and, in particular, in the process of performing regression testing are presented. The positive aspects of using regression testing automation in conditions of lack of resources using various software platforms are indicated. The advantages of using the dynamic selection method for regression tests for automated testing are also given, as well as recommendations for implementing the selection method in existing and beginning projects.

Published: December 2020

This article describes the use of a monocular camera attached to a multirotor perpendicular to the horizon, to recognize visual cues or artefacts (AprilTag) and use it as an anchor for aerial alignment to finally land on it, thus attempting to make autonomous flights safer and usable in slightly hard-to-reach locations. A Hexacopter frame with the DJI N3 flight controller was used for prototyping and realizing the desired algorithm. Factors like wind speed and gusts were taken into account as well as the center of gravity of the multirotor and the position of the molecular camera attached to the copter facing downwards or at a 90-degree angle. The results of the experiments conducted were verified against existing methods like the GPS (Global Positioning System) waypoint mission provided by major commercial Unmanned Aerial Vehicle(UAV) or Flight Controller manufacturers and were also compared to experimental methods presented in related research articles, fairing excellent results

Published: December 2020

The paradigm of communication between people is changing along with global changes in the modern world. This process is related to the integration of technology into everyday life and represents an expansion of the signs and symbolic environment in the field of communication: more and more new images are appearing designed to mark the attributes of the modern world. Pictorial form of communication is a simplified, cost-effective means of communication. That is why it is widely used in education, rehabilitation, navigation systems of public spaces, web and human interaction with cyberphysical systems. However, modern pictographic systems are fragmented and poorly systematized in a constant race for compliance with the requirements of the modern world. They are almost not investigated in their practical application and are limited in their expressive possibilities. This article is devoted to the description of the initial stage of empirical research of pictographic language LoCoS and the stages of development of an alternative keyboard for communication based on it. The conclusion is made about the possibility of the existence of a universal pictographic language on the basis of its semantic and technological improvement.
Constructive Geometric Models with Imaginary Objects
Authors: Voloshinov Denis , Solovjeva Alexandra
Published: December 2020

The article is devoted to the consideration of a number of theoretical questions of projective geometry related to specifying and displaying imaginary objects, especially, conics. The lack of development of appropriate constructive schemes is a significant obstacle to the study of quadratic images in three-dimensional space and spaces of higher order. The relationship between the two circles, established by the inversion operation with respect to the other two circles, in particular, one of which is imaginary, allows obtain a simple and effective method for indirect setting of imaginary circles in a planar drawing. The application of the collinear transformation to circles with an imaginary radius also makes it possible to obtain unified algorithms for specifying and controlling imaginary conics along with usual real second-order curves. As a result, it allows eliminate exceptional situations that arise while solving problems with quadratic images in spaces of second and higher order.

Authors: Bogatyrev Vladimir , Bogatyrev Stanislav , Bogatyrev Anatoly
Published: December 2020

The possibilities of increasing the likelihood of timely service and reducing the average waiting time for requests for inter-machine exchange in distributed real-time computer systems are investigated. The analyzed effect is achieved as a result of redundant multi-way transmissions of packets that are critical to delays, which provide for the replication of transmitted packets with the task for each replica of the path (route) of the sequential passage of network nodes. The condition for the timeliness of the reserved transmissions is that the accumulated waiting in the queues of the nodes making up the path, at least for one of the replicas, does not exceed the maximum permissible time. An analytical model is proposed for estimating the average delays of multi-path redundant transmissions, when determined by the average delivery time of the first of the replicas transmitted in different ways. For requests critical to service delays, the influence of the frequency of reservation (replication) of requests on the probability of their timely service and the average waiting time accumulated at the nodes of the path for the replica delivered first was analyzed.
Constructing K-d Tree on GPU through Treelet Restructuring
Authors: Bulavintsev Vadim , Zhdanov Dmitry
Published: December 2020

With every new generation of graphics processing units (GPUs), offloading ray-tracing algorithms to GPUs becomes more feasible. Software-hardware solutions for ray-tracing focus on implementing its basic components, such as building and traversing bounding volume hierarchies (BVH). However, global illumination algorithms, such as photon mapping method, depend on another kind of acceleration structure, namely k-d trees. In this work, we adapt state-ofthe-art GPU-based BVH-building algorithm of treelet restructuring to k-d trees. By evaluating the performance of the resulting k-d tree, we show that treelet optimisation heuristic suitable for BVHs of triangles is inadequate for k-d trees of points.
