EVALUATION OF THE SCIENTIFIC ACTIVITY OF THE UNIVERSITY DEPARTMENTS BASED ON THE RATING OF THE TEACHING STAFF
Authors: Koshevoy O. S.
Published: June 2022

The scientific activity of universities is one of the most important elements of the educational environment of an educational organization, aimed primarily at providing high-quality graduate training that meets modern requirements for ensuring the fulfillment of strategic tasks of state development.

The purpose of this study was to develop a methodology for evaluating the research work of the university department that meets the general theoretical methods of its organization.

Given the structure of most universities, which is based on institutes (faculties) and departments, it is quite difficult to carry out an objective assessment of the research work of the department, since the teaching staff of the department implements tasks for teaching students in disciplines that are not directly related to the name and scientific direction of the department. The Institute of Cathedral scientific schools also does not reflect an objective assessment of the activities of the entire teaching staff, and is, as a rule, formal in nature. Based on this, the research work of the teaching staff of the departments is evaluated within the framework of a general rating assessment, which has a number of significant drawbacks, both from the point of view of objectivity and the methodology of its construction.

Authors: Oliveira Taynara Nascimento de , Carvalho Alessandro Salles
Published: June 2022

O posicionamento em levantamentos topográficos e geodésicos com uso de receptores GNSS (Global Navigation Satellite System) pode ser realizado com uso de serviços on-line gratuitos e comerciais. Estes, determinam as coordenadas dos pontos de interesse na época e referencial geodésico das efemérides precisas, às quais são usadas no pós-processamento das observáveis GNSS coletadas em campo e difere do sistema geodésico de referência adotado para o SGB (Sistema Geodésico Brasileiro). No Brasil, é empregado na determinação das coordenadas apenas a realização SIRGAS2000 (época 2000,4). É imprescindível a mudança de referencial e atualização das coordenadas para o referencial geodésico oficial no país. Assim, uma ferramenta computacional para automação dos procedimentos e fornecimento de relatório dos cálculos executados internamente, contribui para estudantes e usuários desses serviços de processamento de dados GNSS para posicionamento. O propósito deste trabalho foi desenvolver um software, nomeado de MRefGeo, para realizar a mudança de referencial geodésico e atualização das coordenadas e validar os resultados de sua utilização. No MRefGeo, é possível escolher parâmetros disponibilizados pelo IBGE-PPP (Instituto Brasileiro de Geografia e Estatística - Posicionamento por Ponto Preciso) ou pelo IERS/IGN (International Earth rotation and Reference systems Service/ Institut National de l'Information Géographique et Forestière) para mudança de referencial e modelos de velocidade para o SIRGAS - VEMOS2009 e VEMOS2017. Os resultados obtidos com MRefGeo são concordantes, a nível do milímetro, com os fornecidos pela ferramenta on-line ETRF/ITRF coordinate transformation utilizados na validação das transformações e atualizações.
Contribuição para a Determinação da Separação Geoide e Quase Geoide (SGQG) no Território Brasileiro
Authors: Silva Franck Rosa da , Souza Sérgio Florêncio de , Santos Junior Roosevelt de Lara , Ferraz Rodrigo da Silva
Published: June 2022

A separação entre o geoide e o quase geoide, entendida como a diferença entre as altitudes normal e ortométrica, pode ser da ordem de centímetros, chegando a metros em áreas de grande variação altimétrica, relacionando-se com a densidade das massas topográficas litológicas e a resolução do modelo topográfico utilizado. Neste contexto, o objetivo principal desta pesquisa consistiu em avaliar a SGQG no Brasil, a partir de quatro metodologias distintas. A primeira calculou a SGQG pela diferença entre as altitudes normais e ortométricas. A segunda empregou a anomalia simplificada de Bouguer. A terceira introduziu a correção do terreno e na quarta foi adicionada a correção gravimétrica. O estudo foi desenvolvido utilizando-se dados altimétricos e gravimétricos disponibilizados pelo IBGE, dados altimétricos do SRTM com resolução 3” e do mapa de densidade variável derivado do mapa geológico do Brasil. A SGQG obtida pela primeira e segunda metodologias não apresentaram diferenças significativas entre si. A anomalia simplificada de Bouguer correspondeu, em média, a cerca de 92,5% do total da SGQG no Brasil. Introduzindo-se as correções do terreno e gravimétrica, verifica-se que a combinação destas correspondeu a 7,5% da SGQG, sendo a maior contribuição na região sul, confirmando que essas correções não devem ser negligenciadas, principalmente em regiões de maiores altitudes. O modelo de densidade variável diferiu cerca de 4,7% do modelo de densidade constante, sendo esta diferença maior na região centro-oeste. A principal contribuição desta pesquisa foi a viabilidade da incorporação do modelo de densidade variável e das correções topográfica e gravimétrica no cálculo da SGQG em âmbito nacional.
Um Estudo de Caso sobre o Emprego da Técnica de Voxelização como Método para Generalização 3D de Arborização Urbana em Dados LiDAR Aerotransportado
Authors: Andrade e Silva Daniel , Santos Daniel Rodrigues dos
Published: June 2022

Buscando reduzir o esforço computacional na extração de informações a partir de dados geoespaciais tridimensionais (3D), uma opção é realizar a generalização 3D. Configurando um processo subjetivo de derivação de dados em que são estabelecidos critérios e regras, a generalização 3D permite criar modelos de representação espacial 3D compactos e realísticos, impactando menores requisitos de armazenamento, visualização e análise dos dados. Nesse contexto, o presente artigo tem como objetivo geral avaliar o emprego da técnica de voxelização como um método para generalizar árvores urbanas delimitadas em nuvem de pontos LiDAR (Light Detection and Ranging). Adquiridos em plataforma aerotransportada, os dados utilizados são referentes ao bairro da Pituba no município de Salvador-BA e apresentam densidade média de 8 pontos/m2. Para a delimitação das árvores, os dados foram filtrados e classificados com auxílio de rotinas de processamento implementadas em softwares próprios para nuvens de pontos. Para a voxelização, foram definidas quatro diferentes dimensões mínimas de célula: 0,5 m, 1 m, 1,5 m e 2 m. Os resultados obtidos mostraram a diminuição do número de unidades elementares e a redução do espaço de armazenamento computacional, mantida a eficácia para a extração de informações sobre a localização e a distribuição espacial das árvores delimitadas. Valida-se assim a voxelização como um eficaz método para generalização 3D de arborização urbana em dados ALS.
Locus of Control and Gender as Moderators of Perceived Stress in Indian Adolescents
Authors: Anmol Anmol , Rath Sangeeta
Published: June 2022

Objective: In this study, we examined the effect of locus of control and gender on perceived stress in adolescents. Methods: Using random sampling, 400 adolescents (200 boys and 200 girls) were selected from 5 different educational institutions in the city of Cuttack, India. We administered Rotter’s Locus of Control Scale, and the obtained scores were subjected to an extreme group analysis for shortlisting 200 adolescents (100 boys and 100 girls) with extreme (low and high) scores. Subsequently, the shortlisted students were administered Cohen’s Perceived Stress Scale, and the scores obtained were analyzed using a between-subjects ANOVA. Results: The effect of locus of control on perceived stress was found to be statistically significant, and internal-control adolescents reported lower perceived stress than external-control adolescents. However, both the main effect of gender and the interaction effect (locus of control x gender) were not statistically significant. Conclusion: Our results suggest that adolescents with internal locus of control report lower perceived stress than their external counterparts. We discuss the implications and directions for future research.
Lysurus fossatii (Lysuraceae, Basidiomycota). A new species with simple stem-like receptacle structure, from Argentina
Authors: Hernández Caffot María L. , Nouhra Eduardo R. , Kuhar Francisco , Caeiro Luciana , Domínguez Laura S.
Published: June 2022

Lysurus fossatii, a new Lysuraceae species with unique macroscopic features is described and illustrated. Specimens were collected during field expeditions to remnants of the Espinal forest preserved at Estancia Yucat, South-East Córdoba, in central Argentina. The species is diagnosed by a light yellow peridium when immature, with the surface marked by a reticulum corresponding to the peridial sutures. When young and while still enclosed in the peridium, this species can be distinguished by the presence of a small white stipe completely covered by a green gleba. No actual receptacular structure is evidenced and only the stipe supports the gleba. Phylogenetic analyses highly supported the affinity of this species with L. sphaerocephalus in a close clade of L. cruciatus.

Első izraeli terepmunkám tapasztalatai
Authors: Mars Leonard
Published: June 2022

A tanulményban egy személyes beszámoló keretében foglalom össze első nagyobb, 1966 júliusa és 1968 májusa között Izraelben folytatott terepmunkám tapasztalatait. Hangsúlyozom a „személyes” jelzőt, ugyanis úgy gondolom, hogy a kutató – társadalmi helyzetében és személyiségében megnyilvánuló – személye a kutatás mikéntjének igen fontos tényezője. Az antropológiai kutatás kulcsa az antropológus, ezért egyetértek E. H. Carr kijelentésével: „mielőtt a tényeket vizsgálod, vizsgáld meg a történészt” (Carr 1964: 23), amit saját szaktudományunkra is vonatkoztathatunk: „mielőtt az antropológiát vizsgálod, vizsgáld meg az antropológust”. Carr javaslata különösképpen érvényes a szociálantropológia esetében, mivel kutatásunk szociális személyiségünk egészét mozgósítja, hiszen a részvételt kombináljuk a megfigyeléssel, vagy másképpen fogalmazva a bevonódás és a kívülállás kiegyensúlyozására törekszünk.
The Psychodynamic Psychiatrist and Psychiatric Care in the Era of COVID-19
Authors: Ingram Douglas H. , Best Kimberly
Published: June 2022

Near the beginning of the COVID-19 pandemic, on April 13, 2020, about 50 members of the American Academy of Psychodynamic Psychiatry and Psychoanalysis convened through Zoom to talk about the impact of the pandemic on their practices, their patients, and themselves.∗ They offer their reflections through oral and written comments. Participants were encouraged to organize their contributions around the dimensions of administrative psychiatry, the structure of clinical care, the content of clinical care, the patients’ reported personal experiences, and the psychiatrists’ reported personal experiences. Themes identified and discussed are paradoxical separateness, seeking an optimal interpersonal distance, finding new idioms, reality and symbolism, and loss, mourning, and isolation. The views are noted to touch on only one point early in the arc of the pandemic. A significant body of personal commentary provides an understanding of the roots of themes likely to evolve as the pandemic progresses.
Anticipating Brazil’s Redemocratization in the Early 1980s
Authors: Gaviria Paulina Pardo
Published: June 2022

This article examines Preparação II (Preparation II, 1976) and Tarefa I (Task I, 1982), two works of video art produced by Brazilian artist Letícia Parente during the last phases of Brazil’s military dictatorship (1964–85). The actions recorded in these two videos directly respond to political and social transitions experienced in Brazil in the early 1980s: those implemented by the military government as a way to retain soft control of individual bodies, and those enacted by civilians as empowering manifestations of political participation for social change. This article argues that the explicit manipulation of female bodies in Parente’s work—the injection, labeling, and pressing down upon them—evokes the collective anticipation of Brazil’s redemocratization in 1985. Drawing from feminist and social art history approaches, I compare the strategies used by Parente in these two works of video art with the manipulation of female bodies for artistic purposes included in the artworks of Parente’s Rio de Janeiro-based contemporaries Lygia Pape and Anna Maria Maiolino. Examining how Parente’s videos bear witness to Brazil’s slow transition to democracy provides visual evidence of the ways in which national and international political powers inform individual (female) bodies by both enacting physical control over selected populations and catalyzing intersectional feminist movements.
From Nostalgia to Anachrony
Authors: Hansen James
Published: June 2022

This essay offers a close reading of two rarely discussed videos by moving-image artists Omer Fast and Michael Robinson. Fast’s T3–AEON (2000) and Robinson’s Light Is Waiting (2007) stand as representative of home video appropriation. Utilizing home video’s time-shifting properties, Fast and Robinson returned to home video purchases of cinema and television programs—respectively, The Terminator and Full House—as well as to analog technologies at a moment when they were being eclipsed by the digital. While the return to would-be outmoded or obsolescent technologies is typically tinged with the romanticism of nostalgia, their work pushes through the traps of nostalgia and opens into the times of anachronies. Drawing upon the writing of philosopher Jacques Rancière, anachronies simultaneously configure multiple temporal lines, instilling an ever-changing transformation of personal history, cultural memory, and historical thinking in the present. Revealing the connection between their practice and the multiple temporal lines present via home video appropriation, this essay offers a critical rethinking of nostalgia and anachronism—aesthetically, culturally, and theoretically—through the site of two artists’ moving-image practice.
Editing Legitimacy
Authors: Shi Yifan
Published: June 2022

This research note is a textual comparison between different versions of Deng Xiaoping’s two speeches in May and June 1989 using recently accessible scanned copies of original documents distributed to local officials. It reveals numerous alterations—including both deletions and additions—in the later published texts. The research note suggests that in the context of the early 1990s, these editorial efforts were made to restore the legitimacy of the Chinese Communist Party by highlighting Deng’s image as a pragmatic reformer, maintaining Jiang Zemin’s position as the core of the new leadership, downplaying the party’s internal struggles and corruption, and assuring people that China would continue its market-oriented reform. More broadly, findings in the research note showcase the essential role of propaganda in legitimation under the Chinese communist regime.

Desarrollo de un modelo heurístico para la optimización en el manejo de material en estibas en una bodega
Authors: Manotas Romero Laura , Ramírez Ríos Diana
Published: June 2022

Los problemas enfocados en las bodegas siempre se han caracterizado porque dependen del tipo de negocio que fue analizado. Algunas empresas tienen zonas de cuarentena en sus bodegas y otras no. Algunas tienen out-and-back picking, y otras hacen picking en un solo recorrido para diferentes ítems. Algunas industrias tienen zonas de adelante, otras poseen zonas de almacenamiento a granel, zonas de producto retenido y de producto rechazado. En general, la optimización de las bodegas es realizada según todas las características mencionadas. En la presente investigación se desarrolló una heurística que fue adaptada con los supuestos y criterios de la regla del cube-per-order para la optimización de asignación de espacios unida con algunas de las bases para la optimización de picking, en el que la distancia de la ruta es importante pero no la ruta en sí. La aplicación fue realizada sobre un ejemplo de bodega, con base a la información suministrada por una empresa del sector industrial, en donde el aspecto crítico detectado consistía en conocer la posición óptima de las diferentes áreas y de los productos en las estanterías disponibles en la bodega. Todo esto, de acuerdo con las capacidades de las estanterías y las características de los diferentes tipos de productos que se van a almacenar. El objetivo que se persigue es el de minimizar la distancia total recorrida en un periodo de tiempo evaluado, sujeto a restricciones de espacio y asignación. Se mostrará entonces la mejoría significativa en la eficiencia de una bodega de material en estibas dada la aplicación de la heurística desarrollada.

Authors: Tibaduiza Burgos Diego Alexander , Barrero Pérez Jaime Guillermo , Martínez Ángel Roberto
Published: June 2022

El planeamiento de caminos y la generación de trayectorias son dos aspectos relevantes al momento de dotar a un robot móvil de independencia para su movimiento en un espacio de trabajo. La utilidad de estas técnicas radica en la inclusión de variables como el tipo de sensores usados, la configuración física del robot y su entorno, este último, puede ser fijo o cambiante entre otros aspectos, con las cuales es posible obtener soluciones que brindan robustez al trabajo de dotar de autonomía a los robots. En este artículo se presentan dos algoritmos para el planeamiento de caminos en un robot móvil de configuración diferencial, aunque como se verá es posible generalizarse a otras configuraciones. La primera de estas técnicas está basada en una emulación de la metodología conocida como campos de potencial y la segunda hace uso de los algoritmos genéticos para la obtención de los caminos. En la evaluación de las estrategias planteadas se muestran los resultados de la implementación en software basadas en un entorno físico en el que interactúan un sistema de visión artificial, transmisión inalámbrica y uso de robots móviles tipo diferencial.
Representación efectiva de dinámicas fisiológicas mediante fuzzy rough set: una revisión
Authors: Orrego Metaute Diana Alexandra , Delgado Trejos Edilson
Published: June 2022

Los sistemas biomédicos de última generación registran en intervalos cortos de tiempo la dinámica fisiológica mediante grandes bases de datos. La interpretación adecuada de la información difícilmente puede hacerse por la experticia de un sólo médico, por lo tanto la toma de decisiones se basa sólo en algunas variables seleccionadas. La representación efectiva de variables fisiológicas mediante fuzzy rough set tipo 1 puede ser aplicada para caracterizar y extraer la información relevante de la dinámica fisiológica; sin embargo, estas técnicas poseen el problema de la complejidad de sus algoritmos y alto costo computacional; por lo tanto, se requiere aplicar técnicas de fuzzy rough set tipo 2, asociadas a métodos axiomáticos a través de operadores de aproximación difusa baja y alta como conceptos primitivos para generar un sistema de reducción de dimensiones con tendencia a la disminución de costo computacional en aplicaciones de ingeniería biomédica. En este artículo se presenta la revisión del estado del arte sobre representación efectiva de dinámicas fisiológicas mediante fuzzy rough set, con el fin de determinar la capacidad que poseen este tipo de técnicas para ser incluidas en procedimientos automáticos de toma de decisiones que apoyen el concepto clínico de un especialista.

The practice of hijab fashion gains new meanings. Along with fashion, hijab is beyond religious and political meaning and appears as an object of consumption in Turkey. The effect on the purchasing decision process in Turkey may vary according to the family structure the role and status in the society and the environment of consumers. The convenience sampling method was used in the selection of 448 people to participate in the study. In the research, the survey technique, one of the quantitative research methods, was chosen as the data collection method. This paper has examined to determine the effect of religious attitudes of women wearing hijab on the choice of hijab fashion, type of purchase behavior and the moderating role of reference groups. Within the result of the study, when the relationship between the religious attitude, hijab fashion style and purchasing behavior is examined, it is found that internalized belief dimension affects religion-based purchase, planned purchase, and hijab fashion style. Significant relationships were found between the dimension of traditional religiousness, types of purchase, and hijab fashion style. Traditional religiousness affects, religion-based purchase socialized purchasing behavior, brand-based purchase, and hijab fashion style. When the relationship between dependent and independent variables are examined by participating in the moderating role of the reference groups, it is seen that family, friends and role models play moderating role in this relationship.

The Indonesian Ministry of Research, Technology, and Higher Education always encourages lecturers to publish their scientific works in open access publications. This study explores the meaning of open access publications from the experiences of UIN lecturers. This study uses a qualitative method with a phenomenological approach to identify the interpretation and meaning of lecturers on open access journal publications. This study found that lecturers know about publishing in open access journals and their advantages. They choose reputable journals in their scientific field as their first reference because the journals that fall into this category have a high level of readability and citation. However, the informants stated that they were also pragmatic; they will reconsider the decision to publish in a reputable and open access journal if the publication fee is deemed too expensive. This study uses Hall's meanings concept, whose application is not only to explore the views of lecturers on open access publications but also to explore the actions they take so that their writings can be included in open access publications. Here, the researcher finds the emerging theme that is the importance of collaboration. It is as a way to overcome barriers to open access publishing and also as the key to the productivity of writing articles in academic journals. This study highlights several important themes related to collaboration. The integration of Islamic knowledge with scientific disciplines is an interesting issue when discussing the benefits of cooperation. The results of this study can provide insight into the meaning of open access journals published by lecturers and how they overcome the barriers in this matter. The researcher suggests using a quantitative approach based on our data for future research.

Published: June 2022

The study of museums in almost all leading universities in Indonesia continues to develop from time to time. This research aims to explore the arguments of the campus community about the founding factors and their opinions about the presence and roles of university museums. The Airlangga University History and Culture Museum and the UGM Mandala Majapahit Museum are the main references for this research. A phenomenological approach with in-depth interviews, observations and relevant literature studies is used in this study. Research findings reveal that several factors of the university museums presence are due to the initiatives from university leaders. University museums serve as historical reminders, fulfill educational and research needs, and instill the identity of campus communities. In relation to the role of university museums, the campus community believes that its role is similar to libraries in supporting learning and research activities and even as community service. Considering the importance of university museums, both university leaders and the education ministry authorities are required to provide optimal support, especially by providing official regulations to support the function of museums as part of information institutions at universities.

Pine rosin of Pinus merkusii Jung at de Vriese is produced industrially from a distillation process of pine sap. The high total Indonesian production leads the primary derivatization strategy into several derivates to fulfill the market demand. Abietic acid (AA) is a major compound in pine rosin, used as the object of observation in this study. The general methodology for transformation reported involves using palladium (Pd) and platinum (Pt)-based catalysts. Both are precious metal catalysts to proceed with oxidative dehydrogenative-aromatization of the rosin. The synthesized product provides dehydroabietic acid (DHA) derivatives in high yield. This paper reports that non-precious metal-based catalysts such as iron (Fe), zinc (Zn), or copper (Cu) with iodine (I2) were applied to deliver the reaction by steam cracking without nitrogen (N2) and oxygen (O2) for economical, efficient, and greenway’s catalyst. It was found that a similar product was isolated, including several by-products. Under high temperatures with a various metal transitions and halogen by FeCl3-I2 and Cu(NO3)2.3H2O and ZnCl2 catalyst, four compounds were identified employing spectroscopic methods in the reaction product: 7-hydroxy-dehydroabietic acid (5), 1,7-dihydroxy-dehydroabietic acid (6), 7-isopropyl-1-methylphenanthren-9-ol (7) and polymer (8). This modified pine rosin was mainly used as an emulsifier for the synthetic rubber industry, varnish, ink, paper sizing, etc. The products are determined based on LC-MS/MS, UV-Vis, and ATR-FTIR spectroscopy.

Indigosol blue is one of the dyes that has not been widely studied for photodegradation. This study aims to determine the photodegradation activity of indigosol blue using TiO2/Natural zeolite. TiO2 embedded in natural zeolite was synthesized using the sol-gel method. The synthesis results were characterized using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), and UV-Vis Diffuse Reflectance Spectroscopy (DRS). The characterization of TiO2-zeolite obtained a bandgap energy of 2.62 eV that could be seen in the UV-Vis DRS spectra. UV light is used during the photodegradation process to irradiate TiO2-zeolite photocatalyst. The results show that the optimum mass of natural TiO2-zeolite photocatalyst was 0.02 g with a degradation percentage of 58.3%. The optimum radiation time was 30 min with a degradation percentage of 58.7%, and the optimum concentration of blue indigosol was 600 ppm with a degradation percentage of 58.7%. TiO2/Natural zeolite photocatalyst could degrade indigosol blue dye effectively at the optimum condition.

Akar Nasionalisme di Minangkabau dapat ditelusuri sejak adanya gerakan pembaharuan Islam yang diinisiasi oleh ulama Kaum Muda pada awal abad ke duapuluh. Setelah sukses melahirkan banyak lembaga pendidikan Gerakan ini kemudian mengalami pergeseran menjadi gerakan Sosio-Agama dan Sosio-Politik. Dalam bidang politik gerakan ini mendapat dukungan masyarakat di seluruh pelosok Minangkabau. Bangkitnya kesadaran kebangsaan di Minangkabau diwarnai oleh keberhasilan masyarakatnya menggagalkan upaya pemerintah kolonial menerapkan Goeroe Ordonantie yakni politik pendidikan yang membatasi gerak kaum elit agama (Islam) dalam menjalankan tugasnya sebagai guru agama.

Pesisir Timur Pulau Weh (PTPW) is a water natural reserve conservation area located in the eastern part of Weh Island. The condition of coral substrates in PTPW has suffered a lot of damage based on bleaching cases that have hit Sabang waters in 2016. Coral conditions can be measured by looking at the abundance of fish indicators of the Chaetodontidae group. Therefore, this study aimed to measure coral conditions and the abundance of Chaetodontidae coral fish, as well as analyze the relationship between the percentage of coral cover and the abundance of Chaetodontidae coral fish. Data of coral were collected using the Point Intercept Transect method with a length of 50 meters, while the abundance of fish used the Underwater Visual Census technique and the Belt Transect method with a length of 50 meters and a total belt width of 5 meters. The results showed that the coral conditions in PTPW were in poor to fair condition with the highest cover at The Sumur Tiga site (36.83%) and the lowest at The Ujung Kareung site (11.5%). The highest abundance of Chaetodontidae fish was found at Ujung Seuke site (1253.3 ind/ha) and the lowest was found at Anoi Itam site (186.7 ind/ha). The results of the correlation analysis between the percentage of coral cover and the abundance of Chaetodontidae coral fish showed a positive relationship (r = 0.482), but it was not significant (p>0.05), and the regression equation obtained Y = 17.16x + 166.52 with a determination coefficient of 18.3%, which indicated that the correlation between the two variables was very weak.
