Authors: Eka Putri Niken Aprilia , Tjahjono Arif , Sebayang Perdamean
Published: July 2021

In this research, a modification of polyurethane (PU) sponge material has been made to obtain superhydrophobic-superoleophilic properties. The PU sponge was coated with several nanomaterials such as ZnO, Fe3O4+TEOS, and stearic acid by dip-coating and drop-coating methods. The tests include selective separation of oil and water with a magnetic response. Several types of oil and organic solvents were tested for absorption capacity. The results showed that the PU@ZnO@Fe3O4@SA sponge has a good absorption capacity, from 4.37 mL to 7.37 mL. The fabricated PU sponge could selectively separate oil from water with a separation efficiency above 99%. The fabricated PU sponge also could be magnetically driven by external magnetic fields. From the characterization using 3D OM, the water contact angle was 153.38°, which indicates that the PU@ZnO@Fe3O4@SA sponge is superhydrophobic. And from surface morphology obtained an average pore size diameter of 167.475 μm.

Published: July 2021

Indonesia has the greatest potential for geothermal energy in the world. Geothermal has an important role as an alternative fuel because it is a renewable energy source, but its use has not been maximized. One of the areas that have the greatest potential for geothermal energy in South Solok, West Sumatra. Therefore, this study was conducted to determine the geothermal system in the South Solok area, West Sumatra by using the gravity method. The gravity data processing stage requires some software to get the CBA value(Complete Bouguer Anomaly), map contours of the CBA. Anomaly separation with the butterworth filter method, determination of residual anomaly slice points, and 2D modeling of geothermal systems. Based on modeling, the qualitative interpretation interprets the Complete Bouguer Anomaly map which is suspected as a geothermal prospect area is a low anomaly ranging from 7.9 mgal - 9.4 mgal which is marked in dark blue. Meanwhile, quantitative interpretation produces modeling of the AB and CD slicing with a total of four layers. This layer consists of clay rock as a cap rock, sandstone as a reservoir, granite as a heated rock as a heat source, and the last layer in the form of magma as a heat source. The anomaly modeling of these two sections is dominated by granite rock with a density value of 2500 kg/m3 for the AB section and 2550 kg/m3 for the CD section.

Heavy metal pollutants contained in wastewater can cause health problems for living things around. Minor to fatal health problems can occur due to heavy metal poisoning, mainly caused by Pb(II) metal.. This study aimed to determine the optimum mass combination of rice husk and zeolite to adsorb Pb(II) metal ions in simulated wastewater, and to determine the sensitivity of the analysis method. This study used Solid Phase Spectrophotometry (SPS) to determine the decrease in Pb(II) metal ion levels after being adsorbed by activated carbon from rice husks and zeolites. This study used an experimental method with simulated wastewater samples containing Pb(II) at several concentrations. Pb(II) adsorption processes by rice husk and natural zeolite used various adsorbents' mass ratios. The adsorbents were characterized by using Fourier-Transform Infra-Red (FTIR) Spectrophotometry. Pb(II) analysis during adsorption processes used a single beam UV-visible Spectrophotometer for Solid-Phase Spectrophotometry. This study indicates that the combination of adsorbent from rice husk and natural zeolite can properly adsorb Pb(II) ions with an adsorption capacity of 0.75 μg g-1 and 0.025 μg L-1 for the LoD of the instrument.

Authors: Chu Ha Thi , Le Doanh Huu , Le Thieu Van , Nguyen Binh Bui , Schwartz Janice , Vu Quang Van
Published: July 2021

Background: Pachyonychia congenita (PC) comprises a group of rare autosomal dominant genetic disorders. It is characterized by hypertrophic nail dystrophy, focal palmoplantar keratoderma, follicular keratosis, and oral leukokeratosis. It is associated with mutations in five differentiationspecific keratin genes: KRT6A, KRT6B, KRT6C, KRT16, or KRT17. The case is being reported for its rarity. To the best of our knowledge, this is the first report of PC, from Vietnam, confirmed by genetic analysis.

Case presentation: A four-year-old Vietnamese girl presented with a thickened nail and oral leukokeratosis soon after birth. She was diagnosed with onychomycosis and chronic oral candidiasis and was treated with systemic anti-fungals in children's hospitals and dermatology departments multiple times; however, no treatments were effective. In collaboration with the International Pachyonychia Congenita Research Registry (IPCRR), the clinical features were consistent with a diagnosis of PC type PC-K6a. The genetic testing, performed through the IPCRR, shows a K6a N171K mutation.

Conclusions: The IPCRR helps screen PC's clinical features and confirm a diagnosis at the molecular level, which is beneficial and crucial for validating the condition's clinical impression.

Institutional Framework for Language Policy in Russia: Views for the Future
Authors:   Kazan State Power Engineering University, Yanush Ol’ga , Mukharyamov Nail’
Published: July 2021

Introduction. The study of language planning and policy (LPP) involves the cross-disciplinary interaction of applied linguistics and political science. The need for this is increasing especially in relation to the regulatory and organizational aspects of language regulation in the conditions of modern Russia. Methods and materials. The authors use the techniques of systems analysis and approaches of political institutionalism: normative, rational choice, theory of organizations, historical, constructivist, network. To study the materials of official documents and legislative acts, the method of textual analysis is used. Academic works of foreign and Russian authors are used through the prism of discourse analysis. Materials related to the activities of agencies and actors in the field of LPP, characterized from a structural and functional point of view. Analysis. The normative and agentive properties of LPP in the modern conditions of Russia and its regions are considered by the authors of the article through analytical procedures proposed by foreign scientists. Many developments from Englishlanguage works in this area can be adapted to the tasks of studying political-linguistic relations, taking Russian specifics into account. The ratio of institutional and conversational types of linguistic interactions is considered as a subject of linguistic pragmatics. The main subject of analysis is formal regulatory complexes and agencies specializing in this area. The analysis undertaken by the authors of the article leads to the conclusion that there is no sustainable institutional LPP model in the Russian situation. This applies, in particular, to the de facto and de jure characteristics of bilingualism as a strategic priority proclaimed at the beginning of the 20 th century. In the latest official texts, the emphasis is on strengthening the position of the Russian language. Further, the body of Russian and regional legal acts is marked by features of rhetoric and excessive symbolism. The prospects for institutionalization here are associated with overcoming such normative dysfunctions. Results. The article draws conclusions about the desirability of conceptualizing LPP within the framework of a separate state doctrinal document, as well as a system of information support and implementation of the principles of language cultivation and management.
Political Organization of the World in the Context of Contemporary Megatrends: Scenarios of Development
Authors:   MGIMO University MFA Russia, Lebedeva Marina
Published: July 2021

Introduction. The article examines the scenarios of the political development of the world depending on the megatrends such as globalization, integration, democratization and the opposite trends – de-globalization, disintegration and de-democratization, as well as the current state of the political organization of the world, including the Westphalian system, the system of interstate relations (system of international relations) and political systems of the modern world states. Methods and materials. The political organization of the world is considered as a system consisting of three subsystems. In this regard, the main approach in the study is the systems approach. Scenario analysis is used as a research method. Analysis. Recently interest in scenarios of the political development of the world has sharply increased, which is reflected in the publications of many Russian and foreign authors. The scenarios of the political development of the world in the 21st century, after the crises associated with the terrorist attacks in 2001, the economic crisis that began in 2008 and the crisis in 2020 caused by the COVID-19 pandemic, began to be discussed especially intensively. Most researchers consider such scenarios based on ideas about the possible configuration of interstate relations, i.e. parts of the system of international (interstate) relations. It is shown that this parameter of analysis is important, but insufficient. It is proposed to consider the scenarios of the political development of the world on the basis of how megatrends and trends alternative to them will act, as well as how the political organization of the world will develop. Results. Four parameters of scenario analysis are identified: 1) time parameter in actions of (mega) trends; 2) differentiated actions (mega) trends in many indicators of economic and social interaction; 3) configuration of the leading states in the international arena (part of the system of international relations). This parameter is widely used by various researchers; 4) an evolutionary (smooth) or revolutionary (through conflicts, crises, etc.) way of transforming the political organization of the world. The combination of development in these parameters (it is possible to single out additional parameters) gives a picture of world politics in the future.

Authors: Kuswinarti Kuswinarti , Azka Ilham Asrori , Prasetyo Dwi
Published: July 2021

Background: Liver can be damaged by various factors, including the oxidative stress mechanism. This damage can be inhibited by the application of anti-oxidant. The Annona muricata L. leaf is known to have antioxidant properties. This study aimed to explore the effect of Annona muricata L. leaf extract against hepatitis in rats.Methods: An experimental study was performed on 25 male Wistar rats that were given Annona muricata L. leaf ethanol extract at 200 mg/kgBW, 400 mg/kgBW, and 600 mg/kgBW for eight days. The CCl4 was administrated on the eighth day and the rats were laparotomized on the next day. The average number of normal hepatocytes was counted in one field of view. This study was conducted at the laboratory of Pharmacology and Therapy of the Faculty of Medicine, Universitas Padjadjaran in September–October 2012.Results: The negative control group showed an intact cell membrane, homogenous cytoplasm, and round nucleus, whereas the positive control group showed necrosis marked by a ruptured cell membrane, vacuolated cytoplasm, and degenerated nucleus. The average number of normal hepatocytes counted in the negative control and the positive group was 404.91±34.09 cells and 23.16±7.84 cells, respectively. In the treatment group, the normal hepatocytes were 95.91±20.96 cells (200 mg/kgBW), 74.53±13.59 cells (400 mg/kgBW) and 46.84±8.46 cells (600 mg/kgBW). Statistically significant inhibition was observed (p<0.05).Conclusions: The Annona muricata L. leaf ethanol extract can inhibit liver tissue damages in hepatitis model rats, possibly due to the presence of acetogenins as an anti-oxidant agent.

RESUMO Estudou-se a sobrevivência, a reprodução e a capacidade predatória de Orius insidiosus (Say) sobre o pulgão do algodoeiroAphis gossypii Glover. Plantas de algodoeiro das cultivares Antares, CNPA7H e Acala 90 (respectivamente, glabra, de média pilosidade e pilosa) foram individualizadas e infestadas com quinze ninfas de terceiro/quarto estádio de A. gossypii e, em seguida, liberadas ninfas do predadorO. insidiosus a partir do primeiro estádio ninfal.As avaliações foram realizadas diariamente, quantificando-se sobrevivência e desenvolvimento ninfal; o número de pulgões predados por dia e total; o número de ovos e a população do predador (total de indivíduos gerados pelas fêmeas) e determinada a eficiência de conversão alimentar através da taxa de predação de O. insidiosus. O desenvolvimento ninfal não foi afetado pelo cultivar de algodoeiro. O cultivar Antares favoreceu maior taxa diária de predação para os dois primeiros e quarto estádio ninfal e fase adulta de O. insidiosus. O número de ovos e de ninfas foi menor quando as fêmeas de O. insidiosus foram confinadas no cultivar Acala 90. A eficiência de conversão alimentar nos cultivares Antares, CNPA7H e Acala 90 foram, respectivamente, 4,28; 3,00 e 2,75 pulgões predados para cada ovo gerado pelo predador.

RESUMO O trabalho foi realizado com o objetivo de analisar leite cru comercializado clandestinamente no Município de Mossoró, RN, quanto à presença de resíduo de beta-lactâmicos. Foi utilizado o teste de triagem Delvotest SP. Durante dois meses, foram coletadas amostras de leite cru comercializado em diferentes pontos de Mossoró; as coletas foram semanais, levando a um total de 32 amostras analisadas. Antes de aplicar o teste, as amostras foram preparadas para inativar possíveis inibidores inespecíficos (lisoenzima, lactoferrina etc), em seguida os testes foram realizados de acordo com as recomendações do fabricante. Todas as amostras analisadas foram negativas. Portanto, as amostras estavam livres de antibióticos ou não continham quantidade maior que o limite máximo resíduo (LMR) permitido no leite. A ausência de amostras positivas do leite cru analisado não permite afirmarmos que a população está livre do problema, pois sabese que este alimento não passa por fiscalização e, dessa forma, pode ser responsável por expor ao risco a saúde das pessoas que o consomem.
INTOXICAÇÃO POR PIRRIXIU (BLUTAPARON PORTULACOIDES) EM OVINOS
Authors: Bertier R.M. , Dias R.V.C. , Batista J.S. , Soto-Blanco B.
Published: July 2021

RESUMO Na região oeste do Rio Grande do Norte, diversos surtos de intoxicação em ovinos têm sido atribuídos ao consumo de Blutaparon portulacoides, conhecida como pirrixiu, bredo-de-praia e capotiraguá. No entanto, não há nenhum trabalho na literatura avaliando se realmente ocorre intoxicação por esta planta. Assim, o presente trabalho tem por objetivo determinar se o pirrixiu pode promover intoxicação nos ovinos. Foram utilizadas 3 ovelhas SRD, com aproximadamente 6 meses de idade, saudáveis pesando aproximadamente 15 kg. Elas receberam, como alimento exclusivo, fardos de pirrixiu por um período de 3 meses. A planta e a água foram ofertados ad libitum durante todo o período experimental. Os animais foram diariamente monitorados para determi nação de possíveis alterações clínicas. Após três meses da administração, as ovelhas foram abatidas, sendo coletados fragmentos de intestino grosso, intestino delgado, fígado, rins, rúmen, retículo, omaso e abomaso para análise histopatológica. Também foram coletadas partes aéreas de B. portulacoides para determinação das concentrações dos íons sódio, fósforo, potássio, cálcio, magnésio, cobre, zinco, ferro e manganês. Foi verificada que a alimentação exclusiva de ovinos com B. portulacoides é responsável por distúrbios no trato digestório, caracterizados por amole cimento das fezes e lesões no epitélio intestinal (desprendimento do epitélio das vilosidades intestinais, hiperplasia das células caliciformes, infiltrado inflamatório na submucosa e infiltrado de células mononucleares na lâmina própria). O possível mecanismo da intoxicação é o desequilíbrio osmótico no trato digestório promovido pela deficiência de sódio e excesso de magnésio, potássio e cálcio na planta.

Visibilidad de la agencia de los jóvenes rurales mediante el uso de las redes sociales: el caso del Colectivo JOB - Boyacá, Colombia
Authors: Ballén Robles Dora Carolina
Published: July 2021

En la provincia del Occidente de Boyacá, en Colombia, nació el colectivo JOB Jóvenes Occidente de Boyacá. Este colectivo, conformado por líderes juveniles de los diferentes municipios de la región, hace uso de las redes sociales para visibilizar su agencia. El artículo analiza las formas en que las y los jóvenes visibilizan su agencia. Para ello, se acudió a la técnica de la netgrafía, apoyada de entrevistas y observación presencial de algunas acciones de los líderes juveniles. Las redes sociales son un espacio juvenil, que es buscado y construido por jóvenes, en el que visibilizan sus acciones, resignifican su territorio, promueven la participación y la agremiación juvenil rural. La discusión gira en la necesidad de las y los jóvenes por visibilizar su agencia a través de una mirada crítica y renovada sobre el territorio y su rol.
Ecogubernamentalidad climática en Ecuador. El caso del proyecto Foreccsa
Authors: Cobacango Reyes María Lorena , Sacher William
Published: July 2021

El cambio climático, visto como fenómeno que requiere atención urgente, fundamenta la elaboración de discursos, prácticas y lógicas colonizadoras y modernizadoras que caracterizan una “ecogubernamentalidad climática”. A este régimen de alcance global están atados proyectos de “mitigación” o “adaptación”, que se pueden volver instrumentos de “conducta de las conductas” de poblaciones específicas, en particular poblaciones indígenas. En este artículo se estudia un ejemplo de ello: el proyecto Foreccsa, desarrollado en la provincia de Pichincha, en Ecuador. La metodología de observador-participante “periférico” se combina con el análisis del discurso. Se concluye que el diseño y la implementación de este proyecto están enmarcados en lógicas que apuntan a la homogeneización del comportamiento de las comunidades afectadas, frente al cambio climático, mediante la estandarización de sus conocimientos según lo validado por actores del norte geopolítico. Esa homogeneización, luego, facilita el control sobre las poblaciones, sus recursos y territorios.
Aysén Reserva de Vida: energía, mercantilización y resistencias en la Patagonia chilena
Authors: Fornillo Bruno Martín , Nuñez Jonatan Andrés
Published: July 2021

Este artículo analiza la realidad energética reciente de la región chilena de Aysén. Se examinan las singularidades que le otorgó su tardía incorporación plena al territorio nacional, su composición y las tensiones de la zona, que reflejan problemáticas más amplias de Chile y de la Patagonia. El eje del artículo está puesto en el conflicto abierto en torno al proyecto de instalación de megarepresas denominado HidroAysén, el cual provocó resistencias y potenció experiencias como la cooperativa eléctrica EnercoopAysen. Los objetivos son reconstruir y analizar las consecuencias inmediatas de las reacciones al rol asignado a la región en la matriz energética nacional, por parte del poder ejecutivo. La metodología empleada es cualitativa, sustentada en entrevistas semiestructuradas a informantes clave, representativos de distintos grupos involucrados de forma directa o indirecta en el conflicto. Fueron realizadas en Aysén y Santiago de Chile en enero de 2019. Los resultados dan cuenta de la potencia del movimiento social de Aysén para imponer sus preocupaciones en la agenda política nacional, lo cual posibilitó detener la construcción de las represas, pero no instituir una gestión energética alternativa. La principal conclusión es que, pese a las dificultades impuestas por la normativa neoliberal imperante en Chile, la experiencia del movimiento social de Aysén podría abrir camino para nuevos lenguajes de valoración.

Published: July 2021

Este artículo presenta un análisis crítico sobre el surgimiento y el auge delos conceptos de desarrollo y sostenibilidad, y su aseguramiento en las empresas del sector turístico mediante la creación de certificaciones ambientales. Estas se orientan a aumentar los niveles de competitividad de dichas empresas, al delinear una ruta hacia el paradigma de sostenibilidad, de manera performativa, que posterga la comprensión de la potencia y el alcance del concepto de desarrollo sostenible. Se hace un recorrido por diferentes posturas y perspectivas de análisis del desarrollo sostenible, a partir de los aportes dela escuela alternativa del desarrollo. Estas se han cuestionado y enriquecido a partir de paradigmas emergentes, que desafían las formas hegemónicas de comprenderla problemática. La metodología utilizada es la búsqueda, la clasificación y el análisis de información secundaria contenida en bases de datos especializadas, tales como Scopus y Web of Science, así como la consulta de documentos generados por organismos internacionales involucrados en la temática. Se identificó la existencia de una discusión renovada sobre el papel de las organizaciones empresariales en la búsqueda del desarrollo sostenible. También, el peligro de ceñirse a perspectivas funcionalistas que favorecen usos inapropiados y simplistas de conceptos complejos.

Authors: Schofrin Abril Lucia , Ramírez-España Laura-Sofía
Published: July 2021

Este artículo, enmarcado en la antropología del riesgo y los desastres, recupera el registro etnográfico realizado en la región norpatagónica de Sauzal Bonito, que conforma la cuenca Neuquina, donde se encuentra el conjunto de formaciones hidrocarburíferas no convencionales de Vaca Muerta. La población local está expuesta a la amenaza sísmica provocada por la actividad de fractura hidráulica no convencional o fracking. Entra en la categoría de vulnerable, ya que no cuenta con la información necesaria ni con los recursos suficientes para enfrentar la amenaza, cuya gestión de riesgo debe ser ejecutada por los organismos oficiales estatales (provinciales, municipales y locales). Los resultados sugieren que esa gestión es deficiente. Por tanto, se analiza el cumplimiento de la normativa en materia de prevención, reducción y/o mitigación del riesgo en la localidad de Sauzal Bonito, provincia de Neuquén.

Authors: SONBUL Zeynep Funda
Published: July 2021

Death education should be part of the process, if education means to provide the ultimate aim of human happiness and general well-being. Death education may help parents in tough conversations and support children's understanding of death by forestalling questions in children’s minds at this challenging period such as Covid-19 pandemic. This study aims to analyze the studies on “Death Education” which are indexed in the Web of Science Core Collection, KCI and SciELO databases within the Web of Science All Databases by bibliometric method. Since the first study on “Death Education" was conducted in 1970 in the reviewed literature, studies from 1970 to 2021 were included in the analysis. Web of Science All Data Bases were scanned using the keywords “death education”, “teaching death and dying”, “death and dying course” and “death pedagogy”. 442 publications were analyzed according to databases, research areas, years, authors, document types, journals, countries, languages and visual network maps of 314 publications were anlalyzed according to co-authorship, co-word and co-citation. Findings displayed that the most research was conducted in the field of Education and Educational Research, the most prolific author was Ines Testoni, the most published journal was Death Studies and the most published year was 2020. It was also observed that only two studies from Turkey took place. Given that studies on Death Education in the national literature is scarce and this study is the first bibliometric study on Death Education, it is believed that this study will shed light on future publications on Death Education.

Published: July 2021

Purpose of the study: This study analysed the relationship between Online Social Networking websites and Applications (OSNSA) and university students' academic achievement.

Methodology: In the present research, a quantitative research design was followed, and a survey research type of descriptive research was used in this study. Data were collected from 150 university students using a modified version of The Online Social Networking Sites scale (Paul, Baker, & Cochran, 2012). The correlation was calculated by using the SPSS 22nd version.

Main Findings: The findings revealed a connection between students' time spent on OSNSA and their academic outcomes. The time spent on OSNSA was observed to be strongly influenced by the attention span of the students. In particular, we find that a lower academic output is provided by the greater time spent on OSNSA. Also, attention span was strongly associated with features that influence students' academic success, such as their perceptions of society's social networking outlook, their advantages, and disadvantages of OSNSA, use of OSNSA, etc.

Applications of this study: Many students spend most of their hours on online networking pages, like Facebook, Tok-Tok, and WhatsApp, which are the most common, considering the harmful impact of social media. In certain eyes, social media has embedded a detrimental effect, but it is also used to acquire vital knowledge and social skills for pupils.

Novelty/Originality of this study: This research is different from other studies because it explores the relationship between social networking sites & the application and academic performance of university students belonging from South Punjab by exploring various facets of OSNSA which ultimately promote university students’ academic performance.

Para cumplir con sus obligaciones, el gobierno establece un presupuesto público, en donde tiene en cuenta una serie de ingresos, como los impuestos, gravámenes y tasas, por lo tanto, necesita un sistema tributario que determine las cargas impositivas y los mecanismos para su recaudo. Dentro de los problemas que afectan la economía de los países se encuentra la evasión de impuestos, debido a que esto impide que el Estado reúna los recursos económicos necesarios para asegurar el bienestar de los ciudadanos. El objetivo principal de este artículo es establecer la razón por el cual las personas evaden sus deberes fiscales, para esto se realiza un estudio descriptivo teniendo en cuenta una metodología cualitativa. Inicialmente se definen y caracterizan los sistemas tributarios a nivel mundial, al igual que se analiza su evolución y se identifican cuáles son los más utilizados en países europeos y latinoamericanos; particularmente para Colombia, se analiza la evolución de las normas tributarias relacionadas con los impuestos de renta y de IVA. Posteriormente, se establecen definiciones sobre la evasión de impuestos y se revisan antecedentes sobre la tasa de evasión del impuesto de renta en Colombia. Finalmente, se estudian las causas que motivan a las personas a cometer este delito. Como parte de los principales hallazgos, se encuentra que los países desarrollados mantienen un sistema progresivo, mientras que los latinoamericanos operan con un sistema regresivo, perjudicando en mayor medida a las personas de menores ingresos por medio de impuestos indirectos. Como consecuencia de la desigualdad social y económica y la falta de efectividad del sistema tributario, las personas se sienten influenciadas para evadir impuestos; así mismo, este problema se atribuye a aspectos sociales o culturales, políticos, económicos, jurídicos, técnicos y administrativos.

Authors: Karpenko Sergey , Karpenko Nadezhda
Published: July 2021

Electric power consumption along with a large variety of factors affecting it can be forecasted and modelled by using econometric forecasting methods, including time series and correlation and regression analysis. For the purpose of this research, electric power consumption in the Moscow Region, Russia, was modelled with consideration of economic and climate factors based on 2019–2020 power usage data. A multiplicative model for regional electric power consumption and correlations between electric power consumption and an air temperature as well as a total number of cloudy days a month were built. The results will be helpful for analyzing and forecasting of processes involved in power consumption.

In continuation of the previously published research results (Energy Safety and Energy Economy, iss. 2, 2021), we have developed wire temperature-based mathematical models for overhead power line monitoring. Mathematical models simulate allowable amperage load considering the temperature and an allowable wire sag considering the temperature and amperage. The proposed mathematical models became a base for overhead power line remote control tools being currently tested at power utility companies.

Ice buildup monitoring is essential to prevent wire breakage on overhead power lines. Conventional telemetry systems which are based on load cell sensors have some drawbacks as reflected in this paper. We suggest an innovative device for contactless ice buildup monitoring of overhead power line wires video recording the power line clearance. A specific algorithm for detecting the lowest point of wire sag has been provided. Also, we analyze a possibility of indirect contact sensor-free measurements of a wire temperature when the wire is being covered by icy deposits. A specific buildup type can be determined comparing a dew point and desublimation point as shown in this paper.

The conflict in West Kalimantan is one of the negative impacts of ethnic diversity in Indonesia. To prevent the recurrence of similar conflicts, the participation of various parties, including the education sector, is required by developing conflict resolution education. This article aims to examine three things, namely (1) the theoretical design supporting the model from the educational aspect, (2) examining the initial design of the model, and (3) examining the design implementation of the model. The research was studied using the Sukmadinata approach which simplifies the development research stages of Borg Gall. The results show that (1) there are three educational theories used to develop conflict resolution models in social studies learning, namely progressivism theory, reconstructionism theory, and humanist theory. (2) The development of the initial design of the conflict resolution model in social studies learning includes five aspects, namely syntax, social systems, management systems, support systems, and instructional and accompaniment impacts. (3) The design of the implementation of the conflict resolution model in social studies learning includes planning, targets, and actions.Keywords: Design, Conflict Resolution Model, Social Studies
