Adaptive Pedestrian Stride Estimation for Localization: From Multi-Gait Perspective
Authors: Huang Chao , Zhang Fuping , Xu Zhengyi , Wei Jianming
Published: April 2022

Accurate and reliable stride length estimation modules play a significant role in Pedestrian Dead Reckoning (PDR) systems, but the accuracy of stride length calculation suffers from individual differences. This paper presents a stride length prediction strategy for PDR systems that can be adapted across individuals and broad walking velocity fields. It consists of a multi-gait division algorithm, which can divide a full stride into push-off, swing, heel-strike, and stance based on multi-axis IMU data. Additionally, based on the acquired gait phases, the correlation between multiple features of distinct gait phases and the stride length is analyzed, and multi regression models are merged to output the stride length value. In experimental tests, the gait segmentation algorithm provided gait phases division with the F-score of 0.811, 0.748, 0.805, and 0.819 for stance, push-off, swing, heel-strike, respectively, and IoU of 0.482, 0.69, 0.509 for push-off, swing, heel-strike, respectively. The root means square error (RMSE) of our proposed stride length estimation was 151.933, and the relative error for total distance in varying walking speed tests was less than 2%. The experimental results validated that our proposed gait phase segmentation algorithm can accurately recognize gait phases for individuals with wide walking speed ranges. With no need for parameter modification, the stride length method based on the fusion of multiple predictions from different gait phases can provide better accuracy than the estimations based on the full stride.
Correlation Study of 3D Surface Roughness of Milled Surfaces with Laser Speckle Pattern
Authors: Jayabarathi Suganandha , Ratnam Mani
Published: April 2022

Current studies are focused on the correlation between characteristic features extracted from the laser speckle pattern of machined surfaces and 2D surface roughness parameters. Since milled surfaces are 3D in nature, 3D surface roughness parameters will provide a more accurate representation of the surface. Novelties of this work are: (1) an inexpensive laser pointer, which was used for presentation and was used without any spatial filtering setup for producing the laser speckle pattern; (2) a correlation study, which was conducted between characteristic features extracted from the speckle pattern and 3D surface roughness; and (3) the influence of angle of illumination, lens aperture size (f-number) and shutter speed on the correlation. A highest coefficient of determination of 0.8955 was obtained for the correlation between the gray level co-occurrence matrix descriptor, namely energy, and 3D surface roughness parameter, namely ten-point height S10z, at an illumination angle of 45°, f-number of 16 and shutter speed of 1/100 s.
Quality and Historical Marks of National Interest: The Italian Case Study
Authors: Vinci Giuliana , Maddaloni Lucia , Prencipe Sabrina Antonia , Ruggeri Marco
Published: April 2022

Trademarks are distinctive signs designed to promote and enhance the products/services of companies. In recent years, the concept of quality has asserted growing interest, especially among enterprises, aiming to promote consumers by creating distinctive marks. In Italy, in 2021, the number of filled quality trademarks for products and services will amount to about 81. Through the “Decreto Crescita”, Italy supported Italian companies to limit their delocalization overseas. In this regard, the historical mark of national interest was established, from which Italian companies with a trademark filed for at least 50 years can benefit. Therefore, the study aimed at evaluating two different types of trademarks, quality marks and historical marks, highlighting the main aspects that characterize these two marks as a function of the standards that distinguish them from the most common trademarks. For this purpose, the study focused on evaluating historical brands in Italy to promote their strategic importance and enhance the temporal continuity of the marks. These were considered a new marketing tool to promote know-how and “Made in Italy”, which is particularly useful for the brand image of companies to be competitive in a global market.
Impact of Industrial Agglomeration on China’s Residents’ Consumption
Authors: Zhang Suhua , Bani Yasmin , Selamat Aslam Izah , Ghani Judhiana Abdul
Published: April 2022

Residents’ consumption is a good indicator of people’s livelihoods and one of the motivations driving economic growth. There are many studies on the influencing factors of residents’ consumption; however, few have studied the effects of industrial agglomeration on residents’ consumption, and even fewer have studied the spatial correlation of residents’ consumption. The goal of this paper is to research the impact of China’s manufacturing industrial agglomeration on residents’ consumption from a spatial perspective. Using data on China’s 31 provinces from 2003 to 2019 and the spatial Durbin model, our results show that the manufacturing industrial agglomeration and residents’ consumption present an inverted “U-shape” relationship and that different regions show different effects. Industrial agglomeration in the eastern region is relatively high and has a restraining effect on residents’ consumption, while industrial agglomeration in the central and western regions is at an early stage and promotes residents’ consumption. Therefore, different regions should adopt different industrial agglomeration policies.
Research on Mechanism and Measurement Model for the Effects of Path Dependence on Human Error in Space Station Manipulator Tasks
Authors: Xiao Yi , Jiang Jianjun , Yang Dan , Li Jiaxuan , Wu Jintao , Chen Yang
Published: April 2022

Astronauts’ cognitive and operational processes are partly or absolutely influenced by the thinking and operation habits derived from a previous task or some tasks, which results in disturbance to human error—the disturbance may promote human error or inhibit human error. To explore the mechanism and measurement model of path dependence in human error, this study develops a method for judging the mode of the path dependence symmetric effect, and a mathematical symmetric model for quantifying the degree of the path dependence effect on human error is created. Taking the robotic manipulator teleoperation task as a study object, this study establishes a set of factors that influence the symmetric effect of path dependence, including facilitating or inhibiting human error, and identifies the relationships between these influencing factors. Based on questionnaire analysis, a fuzzy evaluation method for measuring the symmetric degree of the facilitating/inhibiting effect is obtained, by analyzing the simulation data, and the fuzzy method has good convergence, sensitivity and differentiation capabilities.

Authors: Himes Lauren , Shetty Veena , Prabhu Sumathi , Shetty Avinash K.
Published: April 2022

Nipah virus (NiV) disease (NVD) remains a re-emerging public health threat in India. We assessed the knowledge, attitudes, and risk perception of NVD and future vaccine intent among a convenience sample of health care providers (HCP). The primary outcome measures were the knowledge, attitudes, and risk perception scores. Of 261 participants surveyed, 203 (77.8%) had heard of NiV and associated symptoms. The majority (248, 95%) identified the fruit bat as a primary NiV reservoir and 205 (79.8%) were aware of human-to-human transmission via droplets. Only 101 (38.7%) participants were aware that drinking date palm sap is a risk factor for transmission. Most HCP either agreed (117 (44.8%)) or strongly agreed (131 (50.2%)) that NiV is a serious illness. Less than half (121 (46.4%)) were aware of any institutional protocol for NiV; 235 (90.7%) of HCP stated that they need more information about prevention and treatment options. Knowledge scores were significantly higher among physicians compared to nurses whereas nurses and academic providers were more likely to have higher attitudes scores. A majority of respondents (20,779.9%) were willing to be vaccinated and willing to recommend the NiV vaccine to their patients (21,682.8%). Future strategies include education of HCP to bridge the knowledge gaps and enhance preparedness through disease-specific training for NiV infection.
Development of New Strategies for Malaria Chemoprophylaxis: From Monoclonal Antibodies to Long-Acting Injectable Drugs
Authors: Moehrle Joerg J.
Published: April 2022

Drug discovery for malaria has traditionally focused on orally available drugs that kill the abundant, parasitic blood stage. Recently, there has also been an interest in injectable medicines, in the form of monoclonal antibodies (mAbs) with long-lasting plasma half-lives or long-lasting depot formulations of small molecules. These could act as prophylactic drugs, targeting the sporozoites and other earlier parasitic stages in the liver, when the parasites are less numerous, or as another intervention strategy targeting the formation of infectious gametocytes. Generally speaking, the development of mAbs is less risky (costly) than small-molecule drugs, and they have an excellent safety profile with few or no off-target effects. Therefore, populations who are the most vulnerable to malaria, i.e., pregnant women and young children would have access to such new treatments much faster than is presently the case for new antimalarials. An analysis of mAbs that were successfully developed for oncology illustrates some of the feasibility aspects, and their potential as affordable drugs in low- and middle-income countries.

Published: April 2022

Compared to the scour around a single pier, the local scour process around tandem double piers is much more complicated. Based on laboratory experiments in a flume, we conducted the scour process around tandem double piers under an ice-covered flow condition. The results showed that when the pier spacing ratio L/D = 2 (where L = the pier spacing distance, and D = the pier diameter), the rear pier (the downstream one) will intensify the horseshoe vortex process behind the front pier, and the scour depth around the front pier will increase by about 10%. As the pier spacing ratio L/D increases, the scour depth around the front pier will gradually decrease. When the pier spacing ratio L/D = 5, sediment scoured around the front pier begins to deposit between these two piers. To initiate a deposition dune between piers, the pier spacing distance under an ice-covered condition is about 20% more than that under an open flow condition. The results also showed that the existence of the rear pier will lead to an increase in the length of the scour hole but a decrease in the depth of the scour hole around the front pier. The local scour around the front pier interacts with the local scour of the rear pier. The maximum scour depth of the scour hole around the rear pier increases first, then decreases and increases again afterward. When the pier spacing ratio L/D = 9, the scour depth around the rear pier is the least. With an increase in the pier spacing ratio, the influence of the local scour around the front pier on the local scour around the rear pier gradually decreases. When the pier spacing ratio L/D is more than 17, the scour around the front pier has hardly any influence on that around the rear pier. The scour depth around the rear pier is about 90% of that around the front pier.

The Chinese High-resolution Earth Observation System (CHEOS) program has successfully launched 7 civilian satellites since 2010. These satellites are named by Gaofen (meaning high resolution in Chinese, hereafter noted as GF). To combine the advantages of high temporal and comparably high spatial resolution, diverse sensors are deployed to each satellite. GF-1 and GF-6 carry both high-resolution cameras (2 m resolution panchromatic and 8 m resolution multispectral camera), providing high spatial imaging for land use monitoring; GF-3 is equipped with a C-band multipolarization synthetic aperture radar with a spatial resolution of up to 1 meter, mostly monitoring marine targets; GF-5 carried 6 sensors including hyperspectral camera and directional polarization camera, dedicated to environmental remote sensing and climate research, such as aerosol, clouds, and greenhouse gas monitoring; and GF-7 laser altimeter system payload enables a three-dimensional surveying and mapping of natural resource and land surveying, facilitating the accumulation of basic geographic information. This study provides an overview of GF civilian series satellites, especially their missions, sensors, and applications.

Published: April 2022

Para establecer un programa de mejoramiento genético de tomate (Solanum lycopersicum L.) se requiere tener acceso a germoplasma que contenga genes de interés comercial y valor nutricional; previamente, se deben conocer las características y atributos de cada población, lo cual se logra con la caracterización. Con base en lo anterior, el objetivo de este estudio fue evaluar la diversidad morfológica y agronómica de 20 accesiones de tomate nativo del sur de México e identificar aquellas promisorias para conservarlas y usarlas en mejoramiento genético. Las poblaciones se establecieron bajo un diseño experimental  completamente al azar con tres repeticiones. Se registraron 18 caracteres de planta, flor, fruto y fenología. La información obtenida se sometió a análisis de varianza, de componentes principales y de conglomerados. El 82.3 % de la variación morfo-agronómica total se explicó con los tres primeros componentes principales. Los caracteres con mayor valor descriptivo de la variabilidad fueron estructuras florales, tamaño y peso de fruto, rendimiento por planta, longitud de nudos, altura de la planta hasta el primer racimo y precocidad. El análisis de conglomerados y de componentes principales permitió la identificación de cinco grupos. Se identificaron seis poblaciones sobresalientes con los mayores promedios en estructura de la flor, largo de fruto, peso de fruto y rendimiento de fruto por planta.

Published: April 2022

La productividad del frijol de riego sembrado en febrero en la región de El Bajío de Guanajuato, México es afectada por temperaturas altas durante la etapa reproductiva. El objetivo de este estudio fue determinar el efecto de la temperatura alta sobre el rendimiento e índice de cosecha en germoplasma mejorado de frijol de los tipos Pinto y Flor de Mayo e identificar materiales con rendimiento alto en riego. En 2018 se evaluaron 16 materiales de frijol Pinto y 15 de Flor de Mayo. Durante el ciclo se aplicó un riego de presiembra y tres de auxilio. Cada material se sembró en dos surcos de 30 m, y a la cosecha se tomaron al azar seis tramos de 1 m para determinar el número de vainas, numero de granos, producción de biomasa, rendimiento de grano, peso de cien semillas e índice de cosecha (IC). Los grupos se analizaron por separado bajo un diseño completamente al azar y prueba de medias dentro de grupos (Tukey, P ≤ 0.05). Durante la etapa reproductiva las temperaturas diurna y nocturna máximas superaron los 30 y 20 oC, respectivamente. En ambos grupos hubo diferencias significativas (P ≤ 0.05) en las características evaluadas. El rendimiento mayor en los materiales de tipo Pinto lo tuvo la variedad Salinas (3.79 t ha-1) y en los de tipo Flor de Mayo la línea (PS/FM Dolores)-M-9-2-9 (3.27 t ha-1), ambos mostraron número alto de vainas por m2 y granos por vaina. En general, en ambos grupos el IC  resultó bajo. En los materiales de tipo Pinto la correlación entre IC y rendimiento fue positiva (r = 0.75**), mientras  que en el grupo Flor de Mayo la correlación del IC con la biomasa fue negativa (r = -0.74**), lo que mostró la importancia de la capacidad de movilización de fotoasimilados hacia la semilla en condiciones de estrés por calor y la superioridad de los genotipos Pintos.

En el afán de justificar el dominio español sobre los indígenas o de emitir medidas administrativas y tributarias que facilitasen el proce- so de colonización de América, las autoridades de la corona se encon- traron a menudo entre la cruz y el sentimiento del oro; con frecuen- cia no les quedó más que sacrificar el celo religioso a la estabilidad mercantil. Un ejemplo de esto lo da la descripción que hace Luis Capoche, en su Relación general de la Villa Imperial de Potosí, de las circunstancias que acompañaron a la emisión, por parte del Virrey Toledo, de las ordenanzas que intentaron regular la producción y el comercio de la hoja de coca.
Más allá de los likes y los selfies: encontrando contención emocional en un espacio de conexiones ilimitadas
Authors: Vargas Calle Andrea Alejandra
Published: April 2022

El presente ensayo es fruto de una reflexión teórica acerca de los cambios y avances relacionados a dos temas: el impacto del apoyo social durante el sufrimiento físico/emocional; y la fuente de dicho “apoyo social”: vida offline y vida online. La contención emocional es un tipo de apoyo social que, en términos estrictos, alude a un procedimiento profesional; sin embargo, también se relaciona con el consuelo y compañía que se encuentra en un lazo o vínculo social significativo para la persona que lo necesita. Actualmente, el internet y la vida online, nos permite mayor frecuencia en nuestras interacciones, las mismas que pueden llegar a ser la clave para brindar consuelo al interior de los Grupos o Comunidades Virtuales que se especializan en sufrimientos físicos o emocionales.

La noción de justicia y la emergencia de derechos de segunda y tercera generación en la construcción de lo público
Authors: Valenzuela Corales María de Los Andes
Published: April 2022

A lo largo de la historia, la noción de “lo público” camina de la mano con la integración de diversas nociones en torno al concepto de justicia y el reconocimiento de derechos que se garantizan al alero de dicho espacio. El ensayo tiene por objetivo articular una reflexión crítica en torno a la construcción de lo público y su relación con la idea de justicia y la consiguiente incidencia que esta tiene en la estructuración y reconocimiento de derechos fundamentales de tercera generación. Para ello, en un primer momento, nos centraremos en la elaboración de una reconstrucción general de la idea de lo público, a partir de la tesis desarrollada por John Dewey. A continuación, analizaremos la conceptualización de la idea de justicia, a partir de la que ha sido su formulación más destacada a lo largo de estas últimas décadas: aquella propuesta por John Rawls. Finalmente, evidenciaremos las complejidades en torno a la posibilidad de construir la noción de “lo público” desde una base de reconciliación de los principios de libertad e igualdad, ampliando el catálogo de derechos fundamentales protegidos.
Cultura jurídica en Bolivia: motor intrínseco del Statu Quo
Authors: Aliss Sabath José M.
Published: April 2022

A pesar de las denuncias por parte de las ONG, de la defensoría y de trabajos académicos, existe una predominante deficiencia práctica en la aplicación del sistema penitenciario en Bolivia, la cual expresa problemáticas familiares en las últimas décadas. La frustración generada por este fenómeno, aparentemente inamovible, da génesis a una meta-problemática. No es suficiente entender la naturaleza de los problemas jurídicos si no se toma en cuenta el funcionamiento del motor que permite esta predominancia. El entender la funcionalidad de complejos problemas sociales e institucionales a nivel nacional resulta insuficiente si no se puede concebir el contexto político y cultural en el que se encuentran. Desde una perspectiva psicológica y sociológica, se debe explorar “más allá” de tales problemas y considerar sus antecedentes, sus agentes políticos y los “malos hábitos” en la cultura boliviana para determinar qué posibilidad existe respecto a que las ciencias sociales puedan influirlos o combatirlos de forma plausible dentro de la realidad nacional.
¿En qué medida los sistemas alimentarios pueden ser sostenibles y equitativos sin la inclusión plena del trabajo que realizan las mujeres?
Authors: Argandoña Bishelly Elías
Published: April 2022

Los sistemas alimentarios comprenden una red de elementos y actividades necesarias, tales como la producción, comercialización y consumo, entre muchas otras, en la cual la participación y el trabajo de las mujeres es fundamental. Sin embargo, mientras en los datos y políticas no se consideren actoras principales, difícilmente se puede garantizar la sostenibilidad de los sistemas alimentarios. En el presente documento se busca visibilizar el aporte de las mujeres en la producción, intermediación, provisión y consumo de alimentos, así como el trabajo reproductivo y de cuidado, que son vitales para los sistemas alimentarios, y que al obviar su participación difícilmente se puede garantizar que los sistemas alimentarios puedan ser sostenibles y equitativos.

En tiempos de Pawipacha: poner la teoría y las prácticas de políticas públicas en comunicación al día
Authors: Contreras Baspineiro Adalid
Published: April 2022

La teoría de la comunicación se ha enriquecido con el planteamiento de las políticas públicas en comunicación, que condensan un acumulado de conquistas por la democratización de la comunicación y de la sociedad. También la legislación ha abierto caminos de formas de democracia participativa con el ejercicio del derecho a la información y la comunicación. Sin embargo, las prácticas de comunicación en los niveles de decisión sobre estas políticas, no están marchando a la par de la teoría altruista ni de la legislación humanista. Por elcontrario,sehahechoinstrumentalista, funcional a los poderes, desarraigándose de las ciudadanías. En este ambiente, inmersos en un tiempo de incertidumbre (Pawipacha), proponemos poner al día la teoría y las prácticas de las políticas públicas en comunicación, considerando críticamente los siguientes factores: i) interpelar la (in)comunicación en su contexto y relaciones de poder; ii) interpelar las políticas públicas en comunicación centradas en la dinámica mediática, abriéndola a la naturaleza de las redes sociales digitales; iii) interpelar la naturaleza occidental de las políticas públicas, para complementarla con la emergencia vivificante de los paradigmas interculturales; y iv) interpelar la noción de lo público desde las formas de constitución híbridas de lo público y lo privado en la descentralización de las sociedades. Poner al día la teoría, legislación y prácticas de las políticas públicas en comunicación, constituye una oportunidad para retomar las banderas de la democratización de la comunicación y de la sociedad.

Published: April 2022

The purpose of this study is to determine the reservoir condition system of Well C-1. Kamojang geothermal field located in the Quaternary volcanic complex caldera system (0.452 to 1.2 Ma). The volcanic complex contributes to the formation of vapor-dominated high-temperature geothermal systems (250oC). The potential of the electricity produced from this field was 260 MWe. This study describes a new method, namely the 18O isotope of alteration rock, to determine reservoir conditions. Another approach is to use a petrographic analytical form, X-ray diffraction, and isotope 18O and D on some core and cutting samples. Isotope abundances are measured using an isotope ratio mass spectrometer (IRMS). Zoning mineral alteration in Well C-1 comprises the cristobalite-montmorillonite zone, illite-montmorillonite zone, and chlorite-epidote zone. Hydrothermal fluids that generate steam in geothermal systems were derived from meteoric water. These fluids interact with rocks based on the ratio of reservoir water-rock interaction, Well C-1. The research shows that the value of the fraction of oxygen atoms of rocks in the system (1-x) was 0.16. That indicated that the reservoir containing fluid 16% or reservoir is rock-dominated. This research on 18O isotope is a novelty because it differs from what has been done by previous researchers who studied reservoir characteristics using water 18O isotope. Meanwhile, this study uses the 18O isotope of alteration rock to identify reservoir conditions. It is hoped that this method can be used in other geothermal fields.

Published: April 2022

This study examines the mediating effect of fairness perceptions in the relationship between two-way communication in pay system and job satisfaction. Although the relationship between such variables has been generally investigated, the mediating effect of two specific types of fairness perceptions, namely procedural fairness and distributive fairness, has not been thoroughly discussed in organizational pay system research literature. Thus, this study was conducted to fulfil this gap. Self-report questionnaires were utilized to gather data from employees in Malaysian public research universities. The study is also novel in that it utilized SmartPLS to assess the psychometric of measurement scale and then test the research hypotheses. Findings from this study prove that the implementation of two-way pay communication between administrators and employees about pay system has strongly invoked employees’ perceptions of procedural fairness and distributive fairness. Consequently, this fairness perception may lead to a higher job satisfaction. Thus, this finding may be used as important guidelines by senior administrators to understand different paradigms of fairness perception concept and formulate fair pay systems for different job levels and structures to maintain and support their strategies and goals in times of global competition and unpredictable economic situation.
THE MOSQUE DOME ASSEMBLING IN AN ETHNOMATHEMATICAL PERSPECTIVE FOR A LEARNING APPROACH
Authors: Zahroh Umy
Published: April 2022

Ethnomathematics is a mathematics learning approach with cultural media around students. Therefore we need the right approach in the learning process to present mathematics that is close to student life so that students have high motivation in learning mathematics. This study aims to determine the process of making mosque domes and ethnomathematics-based learning by modeling mosque domes. This study uses a qualitative research approach with ethnographic methods. Respondents of the study were dome makers, vault designers, and company managers of Seribu Kubah Co.Ltd. The main instrument is the researcher using observation, interview, and documentation guidelines. The results showed that first, the process of making the mosque dome includes three steps, namely ordering the dome, designing and manufacturing the dome components, and assembling the dome. Second, many mathematical concepts are contained in the dome of the mosque including ellipses, circles, rectangles, and triangles. Due to the application of mathematical concepts in making mosque domes, the results of mosque dome modeling can be used in classroom learning, especially for learning resources for geometry material. In-depth studies of ethnomathematics are applied by certain communities to bridge mathematics practiced in society with mathematics learned in schools.

Published: April 2022

Information and communication technologies (ICTs) are considered an essential tool in business strategy to promote the competitiveness of companies, with their implementation becoming more relevant in times of global crisis, such as the one currently experienced during the Covid-19 pandemic. The research objective of this paper was to design an ICT training strategy for business competitiveness in the agro-industrial sector, starting with the descriptive phase provided in this paper. This research is based on a quantitative approach and includes a detailed description of agro-industrial companies’ current difficulties in using ICTs. A survey-type instrument with closed questions was carried out. In its application, a sampling plan was made, studying 12 agro-industrial companies from the city of Cúcuta; 242 employees were analyzed. It was identified that agro-industrial companies are at a medium level, scoring 92.9% in ICT use in technology, competitiveness factor, and business education. In conclusion, these companies located at a medium level in terms of ICT use of basic software and hardware for the daily tasks that employees must perform based on the completion objectives proposed by the company. However, in the face of a crisis such as the Covid-19 pandemic, the companies must follow an emergency protocol of migrating to new virtual spaces because these become the main resource for their existence. As a scientific novelty, the research shows that despite the tensions caused by the Covid-19 pandemic, and although ICTs provided support for the survival of agro-industrial organizations, the city companies have not found ways or strategies to take advantage of the ICT benefits in communication processes, competitiveness, and strengthening of human capital.

Family caregivers (FC) are the key persons responsible for the health of the elderly, and they need sufficient health information to provide elderly health care. However, a few studies on online social media were used among FC in Thailand. Therefore, this study aims to assess health information seeking for elderly care by FC through online media. The descriptive study was conducted in 11 rural communities. FC refers to a family member responsible for unpaid care of the elderly and has lived with the elderly for more than six months. Based on simple random sampling, the sample size calculated requires 310 samples. The study tool was a questionnaire, in which Cronbach's alpha was 0.89. The data were collected by well-trained interviewers. The statistics used were frequency, percentage, t-test, and ANOVA. The response rate was 91.18%. This study found that most of the FC were female, completed secondary school and higher, married, and still working. This study discovered mean score of health information seeking through online media of 2.08 (SD 1.02) (95%CI 2.69, 2.92). This study also found that age group, elderly care training in the last three months, education level, elderly care knowledge obtained from nurses through communication applications on electronic devices, online video sharing applications, and social media platforms were statistically significant with health information sought through online media. To strengthen health information seeking by FC through online media, all related factors we found were suggested for intervention or further study.

This study aimed to determine the effect of spacing with super fertilization on the lowland rice growth and yield. The study was conducted in the Klagen Srampat Village, Maduran District, Lamongan Regency in DS I 2019, using rice of Inpari 42 variety in an area of 1000 m2. The study was arranged in a randomized block design for 8 treatments of spacing models and super fertilization with 4 replications, namely: (1) spacing models of super double row tight (spacing between rows is 40 cm x 5 cm x 20 cm x 5 cm and in rows 10 cm) + Agrimeth biofertilizer + organic fertilizer with M-Dec bio-decomposer, (2) spacing models of double row tight (spacing between rows is 40 cm x 5 cm x 20 cm x 5 cm and in rows 10 cm), (3) spacing models of super double row (spacing between rows is 40 cm x 20 cm and in rows 10 cm) + Agrimeth biofertilizer + organic fertilizer with M-Dec bio-decomposer, (4) spacing models of double row (spacing between rows is 40 cm x 20 cm and in rows 10 cm), (5) spacing models of super tight (20 cm x 10 cm) + Agrimeth biofertilizer + organic fertilizer with M-Dec bio-decomposer, (6) spacing models of tight (20 cm x 10 cm), (7) spacing models of super symmetric (20 cm x 20 cm) + Agrimeth biofertilizer + organic fertilizer with M-Dec bio-decomposer, and (8) spacing models of symmetric (20 cm x 20 cm). The results showed that the use of a high population of rice plants requires sufficient nutrients, therefore, complete fertilization is needed in the form of organic, inorganic fertilizers and a biofertilizer to increase grain yields. The application of the spacing model of super double row tight accompanied by the application of Agrimeth biofertilizer and organic fertilizer using M-Dec bio-decomposer obtained the best rice grain yield of 8,400 kg/ha with a profit of IDR 26,635,000 and B/C ratio of 2.39, being economically feasible.

The purpose of the article is to investigate the state of carbon dioxide emissions generated as a result of wall materials production and the construction industry as a whole. The paper provides a comparative analysis of housing construction in Ukraine and in some CIS countries. Against the background of the indicators of low housing availability and low relative volumes of housing construction, the issue of high energy consumption remains valid. The absolute and relative volumes of greenhouse gas emissions from economic activity of the population of Ukraine are given. The projected consequences for Ukraine from continued CO2 emissions on the same level and temperature rise are estimated. It is deemed that the most suitable wall material for countries with emerging economies is autoclaved aerated concrete (AAC); since it is a structural and thermal insulating material, it can solve the problem of housing construction.

The paper shows the key priority of low energy consumption and makes emphasis on lowering the density of the produced aerated concrete, reducing mineral additives and cement production expenses.
