SHRUBS AS AN ELEMENT OF THE PARK ENVIRONMENT
Authors: Yudina A. , Kochergina Marina
Published: November 2021

Ornamental shrubs are one of the elements of the formation of the park environment and an integral part of urban landscaping. The paper presents the results of studying the species diversity of shrubs in park plantations in the city of Voronezh. The range includes more than 30 species, decorative forms and varieties of plants. Deciduous species are predominant, while coniferous species account for not much more than 10 %. Deciduous shrubs growing in the parks of the city of Voronezh belong to 14 families. Among them, there are beautiful flowering and decorative deciduous species, as well as plants with attractive fruits. Coniferous species belong to two families-pine and cypress. The cypress family is characterized by the greatest species (form, variety) diversity. The most popular types and varieties of coniferous trees are Western thuja "Smaragd", Western thuja "Danika", Cossack juniper, Cossack juniper"Tamariscifolia". The main types of shrub plantings in park stands are hedges and row plantings. The most common hedges are made of brilliant dogwood and Wanguttaspirea. Less often, groups and tapeworms are used in park plantings. The analysis of the geographical origin of shrubs showed that the largest number of species are introduced − their participation is more than 90%, the share of local species is less than 10%.

Some areas of South Sumatra Province are peatlands scattered in the eastern part, starting from the districts of Musi Rawas, Musi Banyuasin, Ogan Komering Ilir, Muaraenim, and Banyuasin. Around 769,000 hectares of peatland are located in the Ogan Komering Ilir Regency area. Ogan Komering Ilir Regency is an area prone to forest fires. Therefore, it is necessary to conduct research on the characteristics of peat soils in the Ogan Komering Ilir area so that they can be used as consideration in efforts to prevent peatland fires. Sampling was carried out in Kotarayo Village, (Kayuagung District), SP 1 (Pedamaran Timur District), and Tulung Selapan Ilir Village (Tulung Selapan District). Peat soil samples were taken with ASTM D 7015-04 guidelines, and the physical properties of peat soil were tested for samples from the three locations. Based on its physical properties, peat soil samples are classified according to ASTM D4427-84. From the results of the research on peat soils in Kayuagung, Tulung Selapan, and Pedamaran Timur sub-districts, Ogan Komering Ilir Regency, peat soil samples can be classified as sapric-peat soil.

Comparative numerical analysis of Bayesian decision rule and probabilistic neural network for pattern recognition
Authors: Mukha V. S.
Published: November 2021

At present, neural networks are increasingly used to solve many problems instead of traditional methods for solving them. This involves comparing the neural network and the traditional method for specific tasks. In this paper, computer modeling of the Bayesian decision rule and the probabilistic neural network is carried out in order to compare their operational characteristics for recognizing Gaussian patterns. Recognition of four and six images (classes) with the number of features from 1 to 6 was simulated in cases where the images are well and poorly separated. The sizes of the training and test samples are chosen quiet big: 500 implementations for each image. Such characteristics as training time of the decision rule, recognition time on the test sample, recognition reliability on the test sample, recognition reliability on the training sample were analyzed. In framework of these conditions it was found that the recognition reliability on the test sample in the case of well separated patterns and with any number of the instances is close to 100 percent for both decision rules. The neural network loses 0,1–16 percent to Bayesian decision rule in the recognition reliability on the test sample for poorly separated patterns. The training time of the neural network exceeds the training time of the Bayesian decision rule in 4–5 times and the recognition time – in 4–6 times. As a result, there are no obvious advantages of the probabilistic neural network over the Bayesian decision rule in the problem of Gaussian pattern recognition. The existing generalization of the Bayesian decision rule described in the article is an alternative to the neural network for the case of non-Gaussian patterns.

Securities an safety room are important, creating a sense of security all around. managers of buildings, companies or the environment, employ workers as security officers to be safe from various acts of theft. hiring security personnel is not efficient, because it takes a long time, and it is also tiring. To create room security there are many ways that we can do, one of which is by utilizing technology as a way to maintain security. Internet of Things (IoT) is a very promising technological development to optimize the way with smart sensors and smart devices that work together through the internet network. Data from sensor devices that have been processed can be represented to users through various platforms, one of which is Smartphones with the Android operating system. To build a prototyping of this system, the Message Queue Telemetry Transport (MQTT) communication protocol is used, it takes several tools that are components of the IoT, including a micro controller for example a NodeMCU, which is a relay whose function is as a breaker and current connector, a switch as a door sensors, Selenoid Door Lock as an electronic door lock, and power supply as a power supplier for the entire series built with Web App, rogressive Web App (PWA) technology is a web application development method adopted by Google, making web applications appear as if they can run like native applications on each platform, such as native Android, Windows, Mac, and Linux applications. By building a prototyping of this IoT system, it can help monitor and control the security of doors and windows in the room.

Authors: Nanishi Yasushi , Yamaguchi Tomohiro
Published: November 2021

This paper reviews the 35 years of history of plasma-excited MBE, focusing on the special value added to conventional MBE through the usage of plasma-excited molecular beams. These advantages include low-temperature surface cleaning, low-temperature growth, selective-area regrowth and impurity doping. These technologies are extremely important to realizing nanoscale low-dimensional device structures. True band gap of InN was identified only after high-quality InN became available by using plasma-excited MBE. Future prospects of this technology are also included from the device application viewpoint.
Relationship between surface free energy and development process (swelling and dissolution kinetics) of poly(4-hydroxystyrene) film in water and 2.38 wt% tetramethylammonium hydroxide aqueous solution
Authors: Ito Yuko Tsutsui , Kozawa Takahiro
Published: November 2021

With the sharpening of optical images, the capability of resist materials has become a serious concern in lithography. The dissolution of a resist polymer is key to the realization of ultrafine patterning. However, the details of the dissolution of resist polymers remain unclarified. In this study, the relationships of surface free energy with swelling and dissolution kinetics were investigated using poly(4-hydroxystyrene) (PHS) film with triphenylsulfonium-nonaflate (TPS-nf). Developers were water and 2.38 wt% tetramethylammonium hydroxide (TMAH) aqueous solution. PHS and TPS-nf are a typical backbone polymer (a dissolution agent) and a typical acid generator of chemically amplified resists, respectively. The water intake and dissolution of PHS film with TPS-nf became fast with increasing UV exposure dose. It was found that the increase in the polar components (particularly, the hydrogen bonding component) and the decrease in the dispersion component of surface free energy underlie the fast water intake and dissolution.

Published: November 2021

We report on the realization of highly conductive and highly reflective n-type AlInN/GaN distributed Bragg reflectors (DBR) for use in vertical cavity surface emitters in a metalorganic vapor phase epitaxy process. While Ge-doping enables low-resistive n-type GaN/AlInN/GaN heterostructures, very high Ge doping levels compromise maximum optical reflectivities of DBRs. Simulations of the Bragg mirror’s reflectivities together with structural analysis by X-ray diffraction reveal an increased absorption within the doped AlInN layers and interface roughening as major causes for the observed reduction of the optical reflectivity. By adjusting the Ge doping level in the AlInN layers, this structural degradation was minimized and highly conductive, 45-fold AlInN/GaN DBR structures with a maximum reflectivity of 99% and vertical specific resistance of 5 × 10–4 Ω cm2 were realized.

Published: November 2021

The recently demonstrated approach of grafting n-type GaN with p-type Si or GaAs, by employing ultrathin Al2O3 at the interface, has shown the feasibility to overcome the poor p-type doping challenge of GaN. However, the surface band-bending of GaN that could be influenced by the Al2O3 has been unknown. In this work, the band-bending of c-plane, Ga-face GaN with ultrathin Al2O3 deposition at the surface of GaN was studied using X-ray photoelectron spectroscopy. The study shows that the Al2O3 can help suppress the upward band-bending of the c-plane, Ga-face GaN with a monotonic reduction trend from 0.48 eV down to 0.12 eV as the number of Al2O3 deposition cycles increases from 0 to 20. The study further shows that the band-bending can be mostly recovered after removing the Al2O3 layer, concurring that the introduction of ultrathin Al2O3 is the main reason for the surface band-bending modulation.
A Comparison of Vibration based Bearing Fault Diagnostic Methods
Authors: Ooijevaar Ted , Pichler Kurt , Di Yuan , Hesch Clemens
Published: November 2021

This paper presents a benchmark study in which three vibration based bearing diagnostic algorithms are compared. The three methods are a data driven approach developed by the Linz Center of Mechatronics (LCM), a physics based method of Flanders Make (FM) and an approach developed by the Center for Intelligent Maintenance Systems (IMS). Two experimental tests have been performed, an accelerated lifetime test to degrade a bearing and introduce an operational bearing fault and a gearbox test containing various faulty test bearings. The methods are compared based on their diagnostic performance, practical applicability, training and configuration requirements. Based on the accelerated lifetime test, it is concluded that the method of IMS and FM, employing bearing specific features, showed to be more sensitive for early bearing fault detection than purely statistical features used in the method of LCM. On the contrary, the method of LCM does not require specific system knowledge and is not limited to bearing monitoring only. The method is more widely applicable to fault monitoring problems. The methods of IMS and LCM seem to outperform the method of FM in the gearbox test. However, the training and testing data used by those methods were acquired for the same bearing sample and for the same bearing assembly. This could lead to a high correlation between the training and testing data and hence a misleading classification accuracy. Therefore, attention should be paid to the quality of the training data. It is concluded that the training data should comprise all relevant system variations, including e.g. remounting of the bearing, to ensure that the classification is uniquely based on bearing fault related effects. The methods of IMS and LCM require validated training data of both healthy and faulty bearing scenarios, whereas the method of FM relies on training data of healthy bearings only. In practice, the availability of training data of faulty bearings is often scarce and could make the adoption more complicated. The findings presented in this paper serve as a guideline to support the selection of an appropriate method for practical applications.
A New Hybrid Prognostic Methodology
Authors: Eker Omer F. , Camci Fatih , Jennions Ian K.
Published: November 2021

Methodologies for prognostics usually centre on physics-based or data-driven approaches. Both have advantages and disadvantages, but accurate prediction relies on extensive data being available. For industrial applications, this is very rarely the case, and hence the chosen method’s performance can deteriorate quite markedly from optimal. For this reason, a hybrid methodology, merging physics-based and data-driven approaches, has been developed and is reported here. Most, if not all, hybrid methods apply physics-based and data-driven approaches in different steps of the prognostics process (i.e. state estimation and state forecasting). The presented technique combines both methods in forecasting, and integrates the short-term prediction of a physics-based model with the longer-term projection of a similarity-based data-driven model, to obtain remaining useful life estimation. The proposed hybrid prognostic methodology has been tested on two engineering datasets, one for crack growth and the other for filter clogging. The performance of the presented methodology has been evaluated by comparing remaining useful life estimations obtained from both hybrid and individual prognostic models. The results show that the presented methodology improves accuracy, robustness and applicability, especially in the case of minimal data being available.
Forecasting the Transmission Trends of Respiratory Infectious Diseases with an Exposure-Risk-Based Model at the Microscopic Level
Authors: Cui Ziwei , Cai Ming , Xiao Yao , Zhu Zheng , Yang Mofeng
Published: November 2021

Respiratory
infectious diseases (e.g., COVID- 19) have brought huge damages to human
society, and the accurate prediction of their transmission trends is essential for
both the health system and policymakers. Most related studies concentrate on
epidemic trend forecasting at the macroscopic level, which ignores the
microscopic social interactions among individuals. Meanwhile, current microscopic
models are still not able to sufficiently decipher the individual-based
spreading process and lack valid quantitative tests. To tackle these problems,
we propose an exposure-risk-based model at the microscopic level, including 4
modules: individual movement, virion-laden droplet movement, individual
exposure risk estimation, and prediction of new cases. First, the front two
modules reproduce the movements of individuals and the droplets of infectors’ expiratory
activities. Then, the outputs are fed to the third module for estimating the
personal exposure risk. Accordingly, the number of new cases is predicted in
the final module. Our model outperforms 4 existing macroscopic or microscopic
models through the forecast of new cases of COVID-19 in the United States.
Specifically, mean absolute error, root mean square error and mean absolute
percentage error by our model are 2454.70, 3170.51, and 3.38% smaller than the
minimum results of comparison models, respectively. In sum, the proposed model
successfully describes the scenarios from a microscopic perspective and shows
great potential for predicting the transmission trends with different scenarios
and management policies.

Authors: Morisaki Naoko
Published: November 2021

Purpose: The purpose of this study was to measure the tongue pressure of older adults who require nursing care and to clarify the relationship between dysphagia symptoms and tongue strength.
Methods: The participants were Japanese older adults (age: ≥ 65 years) in need of care who were able to communicate with others and agreed to participate in the study. Tongue pressure was measured using TPM-01, a tongue pressure measuring instrument. The Dysphagia Risk Assessment for Community-Dwelling Elderly was used to assess dysphagia. The association between tongue pressure and 12 dysphagia symptoms was analyzed using a one-way analysis of variance.
Results: The average tongue pressure was 23.22 ± 9.9 kPa. Tongue pressure was significantly associated with occasional food spillage from the mouth and sputum formation in the throat during meals or after eating or drinking (p < 0.05).
Conclusions: Decreased tongue strength should be suspected in older adults with food spillage from the mouth or sputum formation in the throat during meals.

Used cooking oil are oils that have been used for cooking in restaurants, hotels, food industries, and households. They are dangerous waste when inappropriately disposed since it can interrupt the sewer system or be illegally reprocessed. To combat the issue, the government of Jakarta designed the UCO to Biodiesel supply chain in the Governor’s Regulation number 167 of 2016. However, it has yet to manage households despite potentially producing 210.465,31 litres of UCO per day. The goal of this community service is to create a collection system and to increase awareness of the dangers and potential of UCO in Bassura City Apartment, located in East Jakarta, which did not have UCO collection system. The collection system considers sustainability in terms of not only the environment but also social and economic. The community service is split into five steps: creating local partnerships, supply chain planning, awareness raising by socialization, monitoring and evaluation. Local partnership was created between the local mosque Al-Falah as local UCO collector, BeliJelantah the medium sized UCO collector, and Universitas Bakrie. UCO collected by Al-Falah is bought by BeliJelantah at a rate of Rp4,000.00 /litre. BeliJelantah provides basic equipment such as jerrycans and sieve. Socialization was partially done regularly before sermon and online due to Covid-19 restrictions. Since the implementation of the collection system, Al-Falah mosque has collected 33 Litres which was converted into Rp134,000.00. Sustainability of the collection of used cooking oil will be carried out by residents and the DKM Masjid in direct coordination with BeliJelantah by taking a minimum of 2 jerrycans with a volume of 18 litre or the equivalent of 36 litre. This system can be scaled up by increasing partnerships with more local groups and local management.
Optimal Combination of Multivariate Filter Feature Selection and Classifier for Speech-Based Depression Detection
Authors: Sharma Surbhi , Bustamante Anthony J.
Published: November 2021

In this paper, we have focused to improve the performance of a speech-based uni-modal depression detection system, which is non-invasive, involves low cost and computation time in comparison to multi-modal systems. The performance of a decision system mainly depends on the choice of feature selection method and the classifier. We have investigated the combination of four well-known multivariate filter methods (minimum Redundancy Maximum Relevance, Scatter Ratio, Mahalanobis Distance, Fast Correlation Based feature selection) and four well-known classifiers (k-Nearest Neighbour, Linear Discriminant classifier, Decision Tree, Support Vector Machine) to obtain a minimal set of relevant and non-redundant features to improve the performance. This will speed up the acquisition of features from speech and build the decision system with low cost and complexity. Experimental results on the high and low-level features of recent work on the DAICWOZ dataset demonstrate the superior performance of the combination of Scatter Ratio and LDC as well as that of Mahalanobis Distance and LDC, in comparison to other combinations and existing speech-based depression results, for both gender independent and gender-based studies. Further, these combinations have also outperformed a few multimodal systems. It was noted that low-level features are more discriminatory and provide a better f1 score.
Qur’an Recitation Therapy as Anxiety Treatment
Authors: Marchira Carla Raymondalexas
Published: November 2021

Anxiety is an uncomfortable, pleasant, indistinct and pleasant feeling with autonomic symptoms. Many internal and external factors cause anxiety in a person. The human body tries to maintain homeostasis at all times. Anything that disrupts homeostasis is defined as a stressor by the body. To compensate for stressors and to restore homeostatic equilibrium, physiological adaptations occur in response to stress. This adaptation involves a hormonal cascade along the HPA axis, namely the release of corticotropin-releasing factor (CRF) which stimulates the release of adrenocorticotropic hormone (ACTH) and causes the release of stress hormones (glucocorticoids and epinephrine) from the adrenal cortex. Glucocorticoids will provide negative feedback (negative feedback) to the hypothalamus, thereby reducing the release of CRF. Non-pharmacological intervention anxiety that has lower side effects is safer and can be used for a more extended period compared to anti-anxiety drugs. The recitation of the Al-Qur'an generates alpha waves, which are waves that appear when someone is relaxing. Increased alpha waves can reduce symptoms of anxiety.

Modern technology today, especially in the world of technology Robots are developing very rapidly. Many developed countries are competing and vying to make increasingly sophisticated robots. In Indonesia, robots have also begun to develop. Developments in the field of robotics are also able to have a positive impact in the industrial sector. One example is the process of moving an item/object from one place to another. This study aims to test the motion system, namely a DC motor that functions as a motor for carrying goods. The method used is input from commands given by the user via a smartphone with voice access. As an intermediary, a bluetooth connection is used so that commands can be sent from a smartphone to the control circuit. The controller used is the AVR type, namely atmega 328 on the Arduino Uno board. At the output, there are relays and current amplifiers that function as motor drivers. The user will give orders via a smartphone where on the smartphone runs an application, namely a voice to text converter. The application will convert the human voice into text and send via bluetooth to the controller. The Arduino controller will identify the command code and execute it, namely controlling the robot's motion in the direction desired by the user, for example forward, backward left and right or towards a predetermined point.

Published: November 2021

Sukuk or Sharia bonds are one of the investment instruments in Indonesia. Since the 19th century, Sukuk has become popular with investors. Several previous studies found contradictory results that macroeconomic variables have a relationship and influence on Sukuk by observing the year before the pandemic. This study uses a quantitative descriptive method with a Vector Autoregression (VAR) approach. Through the optimum lag value, namely, lag 3, statistically it was found that there was a significant relationship between the variables of GDP, interest rates, and the exchange rate on Sukuk. In addition, several analysis results found a causal relationship between these variables.

Over a year has passed since the beginning of Covid-19 pandemic and the introduction of measures to limit the spread of the pandemic in Latvia. These have resulted in changes in all spheres of young people's lives, including the way they study and exercise. This study examines the role of Generation Z physical activity as a means of maintaining the well-being of the emerging workforce and the choice of teaching methods by different age groups and genders as well as the finances spent on it. The research methods include critical content analysis of scientific literature on Generation Z, modern teaching methods and the role of physical activity in young people's lives as well as descriptive statistical data analysis of primary data obtained from a questionnaire. The authors found positive correlation between age, gender, the occurrence of depressing mood or anxiety and engagement in physical activity and also identified that Generation Z spends less financial resources for their physical activities and well-being insurance (e.g., the empirical study shows that 84% of respondents spend under 20 hours per month on physical activity, with Chi-Square test p = 0.001); additionally, the study shows that the use of such teaching methods as group work, seminars and webinars for promoting physical activities are efficient under the Covid-19 pandemic situation, except for responders aged 16 – 19, who do not enjoy seminars and conferences (p=0.002) and webinars (p=0.001), albeit other age groups do not mind these teaching methods as well as group work, as shown by Chi-Squared Test (p>0.05).

Published: November 2021

El Libro Didáctico (LD) es un material pedagógico muy utilizado en las escuelas públicas brasileñas, sirve para dar soporte teórico a docentes y estudiantes de Educación Básica y que acaba influyendo en el desarrollo de las clases. El objetivo de esta investigación fue identificar los criterios de elección, la forma de uso en el aula y la evaluación de los docentes de secundaria que laboran en Confresa / MT en la LD de Química. Esta encuesta descriptiva y exploratoria se realizó en 2019 e involucró a 15 profesores de Química de las 09 escuelas que ofrecen la escuela secundaria en la ciudad. Se utilizó un cuestionario que contenía 15 preguntas abiertas. Los docentes investigados adoptan la contextualización y los contenidos abordados como criterios para la elección de la DA. En cuanto a la evaluación y uso de LD, además del considerable uso de este material didáctico, afirman que LD es un medio de investigación en la elaboración y uso en clases. El LD fue elegido mediante votación en la asamblea, en base al análisis cuidadoso de cada Guía de Libros Didácticos (GLD) que presentó al Programa Nacional de Libros y Material Didáctico (PNLD). El estudio también reveló que la DA es bien evaluada por la mayoría de los profesores, principalmente en lo que respecta a la contextualización y los lenguajes utilizados que consideran apropiados. Por tanto, la DA acaba influyendo en el desempeño de los profesores de Química y en consecuencia en la construcción del conocimiento escolar de los estudiantes.
História da Matemática e Tecnologias Digitais: do que tratam três decadas de teses e dissertações?
Authors: Sánchez Ivonne C. , Castillo B. Luis Andrés , Mendes Iran Abreu
Published: November 2021

Neste artigo se descrevem resultados parciais de uma pesquisa vinculada num projeto guarda-chuva aprovado e financiado pelo Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) sob a coordenação do Prof. Dr. Iran Abreu Mendes e intitulado História para o Ensino de Matemática na Formação de Professores e na Educação Básica: uma Análise da Produção Brasileira (1990 – 2017). Neste desdobramento, temos o propósito de indagar em que termos as Tecnologias Digitais são usadas nas pesquisas de História da Matemática, para o ensino da matemática? A abordagem metodológica nesta pesquisa é de tipo bibliográfica, pois o objeto de estudo são as teses e dissertações disponíveis no acervo do Centro Brasileiro de Referência em Pesquisa sobre História da Matemática (CREPHIMat). Das 728 produções acadêmicas-científicas foram filtradas apenas 23, que tiveram presença de tecnologias digitais no corpus do trabalho de maneira direta ou indireta. O mapeamento permitiu constatar que as tecnologias digitais mais usadas neste recorte são os softwares de Geometria Dinâmica, dentre eles, o GeoGebra. Além disso, foi identificado que o uso dado a este tipo de software é quase sempre o mesmo, como substituto do quadro branco, como planilha ou como kit de desenho geométrico o qual deixa sem explorar as vantagens desta tecnologia digital.

Entre los hallazgos se menciona que el aprendizaje cooperativo contribuye a mejorar las relaciones en el aula, su práctica facilita el desarrollo de habilidades cognitivas y sociales, siendo una conclusión de interés el que su aplicación orienta la enseñanza bajo un enfoque constructivista.
Humanidades en interdisciplina
Authors: Gonzalez Daniela Soledad
Published: November 2021

El presente artículo busca poner en valor los aportes de las Ciencias Humanas a la construcción interdisciplinar de conocimientos relacionados con problemáticas que exigen la aplicación urgente de nuevas estrategias de comprensión y acción como las siguientes: comportamientos sociales disfuncionales en las redes sociales, adicciones, trastornos de la alimentación, manipulación de la información en las redes y crisis de angustia existencial. Se argumenta que la inclusión o potenciación de la injerencia de las Humanidades en los estudios interdisciplinares orientados a prevenir la aparición o el agravamiento de dichas problemáticas y otras afines tiene como consecuencia mejores resultados. En primer lugar, se discute el significado de la interdisciplina y el papel de las Humanidades en ella. Luego, se presenta como ejemplo de inclusión de las Humanidades en los proyectos de intervención socio-cultural interdisciplinares un proyecto que se llevó a cabo en General Alvear (Mendoza, Argentina), cuya implementación se basó principalmente en una serie de talleres de reflexión en torno a diversos objetos culturales (publicidades, propagandas, humor gráfico, videos, etc.) dictados por investigadores de las diversas áreas del conocimiento. El trabajo se cierra con una conclusión.
