Published: April 2021

Background: The covid pandemic started from Hubei, Wuhan in December 2020 then covered many other countries including India. Understanding the demographic and clinical characteristics of deceased COVID-19 patients could inform public health interventions focusing on preventing mortality due to COVID-19. The present study was done with the objective of studying the socio-demographic and clinical profile of deceased patients with coronavirus disease.Methods: This is a hospital based cross-sectional study on 1190 deceased patients of coronavirus disease in a tertiary care hospital of central India which is a dedicated covid hospital from 11 March 2020 to 28 February 2021. Socio-demographic and clinical characteristics of deceased patients were recorded.Results: Overall case fatality rate was 13.24%. Maximum number of deaths occurred in the month of August 2020 and September 2020 were 372 (31.26%) and 477 (40.08%). It was higher in the males 791 (66.47%) as compared to females 399 (33.53%), but the difference was not significant. The most common symptom was fever on hospitalization 924 (77.65%), followed by generalized weakness 771 (64.79%). 352 (29.58%) patients died within 24 hours of the admission to hospital. Hypertension and type 2 diabetes mellitus were the most prevalent morbidity in 557 (46.80%) and 357 (30.00%). It was found that 232 (19.50%) deceased patients had oxygen saturation less than 50% on admission.Conclusions: Higher age and presence of co-morbidities at the time of admission were significantly associated with mortality.

Background: To determine the knowledge, awareness, and willingness towards eye donation among paramedical health care providers, public and students from schools and colleges around Tirunelveli district, Tamil Nadu, Southern India.Methods: It was a cross-sectional, observational study conducted from November 2019 to January 2020. A structured questionnaire regarding knowledge (K), awareness (A), willingness (W) for eye donation was used to elicit responses in the age group of more than 16 years. Participants were paramedical health care providers working in tertiary eye care hospital, school and college students, and attenders accompanying patients (addressed as public). Responses were collected from 1803 participants and analyzed statistically.Results: Most of the participants had knowledge about the facts of eye donation, such as 96.8% knew that it could be donated after death, and 55% knew that eyes were enucleated within 6 hours after death. 56.2% admitted that lack of awareness is the reason for not donating eyes; 23.8% said that the family members are objecting to eye donation. Social media was proposed as the best source of information about eye donation. Subjects with an age of fewer than 30 years were willing to donate (the odds ratio was 1.90). However, they had less knowledge (p value=0.105) and awareness (p value=0.02) about eye donation than more than 30 years.Conclusions: Even though awareness and knowledge about eye donation and willingness to pledge eyes are there, self-conscience regarding the need for donor corneas to meet the requirement of corneal blindness plays a pivotal role.

Authors: Surendra Rao Shreekantha Koteshwara , Malik Deepak , Pradhaban Gowthama , Usman Mohammed
Published: April 2021

Between 2017 to 2020, A prospective case series for assessment of short-term outcomes was carried out on 10 shoulders with 3 being bilateral cases and diagnosed as neglected posterior dislocation of shoulder at a tertiary care centre and treated with the Modified Mclaughlin procedure. All patients had articular defect ranging from 27-46% as confirmed with computerised tomography. All the surgeries were carried out by a single team of surgeons. After 24 weeks follow up of 10 shoulders with mean age 32 years, all patients were found to have excellent results in terms of ROWE and constant score. Patients had significant reduction in VAS score. Timely diagnosis of articular involvement plays a vital role in management for which computed tomography has a pivotal role. Depending upon the articular involvement, line of management is to be decided. So, it can be concluded that, in cases of articular defect >25% following posterior dislocation of shoulder, better outcomes can be achieved with modified Mclaughlin procedure in terms of radiographic union and clinical scoring.

Authors: Muthulatha A. , Tamilselvam Bhanupriya , Shanmugam Srikanth , Pramodhini S.
Published: April 2021

Background: Onychomycosis and onychodystrophy are both characterised clinically as disruption of nail plate characterised by thickening, disfiguration and discolouration. Onychomycosis in onychodystrophy is a diagnostic challenge. Similarly, onychodystrophy could also be treated unwarrantedly for fungus. Hence this study was carried out to determine the prevalence of onychomycosis in patients with onychodystrophy and to study the risk factors associated with the same.

Methods: This descriptive study was done in 50 patients with onychodystrophy attending DVL OPD in a tertiary care hospital. After getting informed consent the nails were cleansed with absolute alcohol and nail clipping was taken for KOH and culture. The results were entered in a master sheet and analyzed.

Results: Onycholysis, onychomadesis, chromonychia, thickened nail plate and loss of cuticle were the common features observed. Culture from 13/50 (26%) patients were found to be positive for fungal growth. In 13 patients with onychomycosis, 5 patients belonged to more than 50 years, seven patients (53.8%) were housewives. Three patients with onychodystrophy had psoriasis of which 2 (15.4%) patients proved positive for onychomycosis. Aspergillus niger 10 (76.9%) was the most common organism followed by Rhizopus 2 (15.4%) patients and 1 (7.7%) patient with Geotrichium candidum.

Conclusions: We concluded that prevalence of onychomycosis in patients with onychodystrophy was 26%. Male gender, age >50, household activities and wetworks were associated risk factors of onychomycosis. Since clinical diagnosis of onychomycosis in onychodystrophy is difficult, appropriate lab investigations like KOH mount and fungal culture should be made mandatory to enable better patient care and clinical outcome.

Actitudes de adolescentes hacia la salud: evaluación de un programa escolar de promoción de la salud en Sevilla, España
Authors: Lima Serrano Marta , Neves de Jesus Saul , Lima Rodríguez Joaquín Salvador
Published: April 2021

Se examinaron diferencias en las actitudes hacia la salud en el alumnado de cuarto año de educación secundaria obligatoria de Sevilla, el cual fue dividido en dos grupos en función de su participación en el programa "Forma Joven" de promoción de la salud. Se realizó un análisis descriptivo y bivariante. No se observaron diferencias significativas en las características sociodemográficas de los dos grupos, considerándose homogéneos. Las actitudes también fueron similares en ambos; únicamente se encontraron diferencias estadísticas en el grado de peligrosidad asignado a dos de las trece situaciones viales expuestas: "no usar el cinturón de seguridad" e "ir en un vehículo cuando el conductor ha bebido", siendo menor el asignado por los participantes en el programa. Esto coincide con lo verificado en trabajos previos e invita a reflexionar sobre la falta de efectividad de este tipo de programas. En el caso del programa "Forma Joven" podría atribuirse a una deficiente sistematización en su implementación. Sería recomendable proponer intervenciones para aumentar su efectividad.
Alfredo Lanari, un estilo de investigación clínica
Authors: Romero Lucía
Published: April 2021

La institucionalización de la investigación clínica en la Argentina adquirió su máxima madurez a partir de la creación, en 1957, del Instituto de Investigaciones Médicas de la Facultad de Medicina de la Universidad de Buenos Aires, y del impulso de quien fuera su director durante casi 20 años, Alfredo Lanari. En este trabajo analizo las modalidades mediante las cuales esta figura construyó un estilo de investigación clínica y una posición de referente en la medicina local que le permitieron llevar adelante dicha realización institucional. Esta construcción fue fruto de una empresa personal pero al mismo tiempo abrevó en un contexto más amplio de transformaciones en la medicina mundial y en la Universidad de Buenos Aires. Esta investigación se llevó a cabo combinando el uso de fuentes orales (entrevistas a miembros del Instituto de Investigaciones Médicas, integrantes de la revista Medicina y de la Sociedad Argentina de Investigación Clínica) y documentales (legajos académicos y artículos científicos).
¿Quién es el Dr. Alvarado?
Authors: Jauretche Arturo
Published: April 2021

Este texto, escrito por Arturo Jauretche, recupera la figura del Dr. Carlos Alberto Alvarado (1904-1986) quien, en tiempos en que Ramón Carrillo era secretario de Salud Pública de la Nación, dirige una campaña que logra controlar el paludismo en el noroeste argentino con una reducción muy importante del número de casos, alcanzando una amplia repercusión mundial. En 1955, el Dr. Alvarado es separado de su cargo por la Revolución Libertadora, momento en que la Organización Panamericana de la Salud lo designa asesor regional y entre 1959 y 1964 lo nombran jefe del programa de erradicación de la malaria de la Organización Mundial de la Salud, en Ginebra, Suiza. A su regreso al país en 1966, organiza el Plan de Salud Rural, creando para ello la figura del "agente sanitario" y la "ronda sanitaria" anticipándose a conceptos que varios años después se plasmarían en la Atención Primaria de la Salud. El texto de Jauretche fue publicado originalmente en 1967 en el libro Los profetas del odio, por la editorial de Arturo Peña Lillo, editor de los grandes títulos del "pensamiento nacional" argentino. Su reedición en la sección "Memoria e historia" es un modo de rendir homenaje a una de las figuras indiscutibles de la Salud Pública argentina.
Autocuidado, adherencia e incertidumbre: tratamientos biomédicos y experiencias de pacientes en el dolor crónico de la migraña
Authors: Del Monaco Romina
Published: April 2021

En este escrito se exploran y analizan, desde las ciencias sociales, algunas particularidades de los tratamientos para la migraña desde un enfoque relacional que articula los dichos de los profesionales con las experiencias y prácticas de los pacientes en los servicios de salud y en sus trayectorias de cuidado cotidianas con este dolor. Se realizó una investigación cualitativa a través de entrevistas semiestructuradas a médicos neurólogos y pacientes en un hospital público de la Ciudad Autónoma de Buenos Aires. Se observan un conjunto de procesos por medio de los cuales la biomedicina delega en los pacientes parte de la responsabilidad del curso de su dolencia a través de una lógica de autocuidado. Los sujetos deben realizar numerosos cambios en sus modos de vida a fin de evitar la aparición de los dolores de cabeza. Sin embargo, al no existir certezas en torno a la eficacia de estas modificaciones, la cotidianidad se recubre de incertidumbre y de la exigencia de seguir pautas de cuidado cuyo cumplimiento es valorado no solo por los profesionales sino también socialmente.
Health statistics aren't born in a cabbage patch: Jesuits, political arithmetic, stigmergy and oligopticons
Authors: Carvajal Yuri , Yuing Tuillang
Published: April 2021

By analyzing the content and network of production of a map from 1751, created by the circular mission of the Jesuits in Chiloé (an archipelago located off the southern coast of Chile), that contains birth, death and population data, this article discusses the role that health statistics play historically, philosophically, technically and sociologically. In doing so, the article seeks to comprehend the genesis of a process of production of data and references in order to debate what health statistics are composed of, what ends they are used for, what their connection is to the formation of collectives and the differential conditions of possibility that exist for producing statistics. We attempt to develop hypotheses that demonstrate statistics as a hybrid articulation between diverse elements, epistemological, biopolitical, historical and philosophical in nature, with facets at once religious and demographic, ontological and ethnic, scientific and governmental.
Trójai faló és fügefalevél: a populizmus szerepe a globális demokráciakrízisben és posztmodern autokráciákban
Authors: Benedek István
Published: April 2021

It is my contention that populism could be an appropriate framework to understand and link the phenomena of global crisis of democracy and spread of postmodern autocracies. In order to substantiate this claim with the method of literature review, I have examined first the characteristics of these phenomena and then I have focused the nature of relationship between them, in particular with regard to the complex system of stability of new types of autocracies, in which, I think, populism playing a key role. Populism, understood it as an autocratic interpretation of democracy and representation, could be a particularly dangerous Trojan horse for democracy. Above all, because of its idea of a single, homogeneous and authentic people that can be genuinely represented only by populists, and because of this representative claim is a moralized form of antipluralism. In addition, populism is also an important feature of postmodern autocracies, especially of electoral autocracy. By means of populism, it is possible for these regimes to camouflage and even legitimise the autocratic trends and exercise of power, as well as the creation an uneven playing field for political contestation behind their formally multi-party elections and democratic façade. As a radical turn towards traditional forms of autocracies would be too expensive, postmodern autocrats need manipulated multi-party elections and other plebiscite techniques that could serve as quasi-democratic legitimation, as well as populism that could transform political contestation to a life-and-death struggle and, provides other important cognitive functions. Therefore, populist autocracy, as a paradigmatic type of postmodern autocracies, will remain with us for a long time, giving more and more tasks to researchers involved in them.

Published: April 2021

Coconut is a potential commodity to be developed. The development of coconut agro-industry can increase product added value. Value-added analysis needs to be carried out to find out how much the added value of processed coconut product is. The calculation of basic costs also needs to be done to find out how much it costs to produce 1 unit or 1 kg of product. This research is beneficial as decision support through useful information for coconut farmers in increasing their income. Value-added analysis in this study used the Hayami method, while the calculation of the cost of processing involves fixed costs, variable costs, working hours, and production capacity. The study was conducted in Indragiri Hilir Regency, Riau. Product selection is based on previous research, which shows that prospective products developed are coconut oil, coconut sugar, and shell charcoal. Data collection was carried out in three districts, namely Mandah, Reteh, and Enok. The results showed that each product's added value was IDR 1,037.79 per kg in coconut sugar processing, IDR 760 per kg in coconut oil processing, and IDR. 249.98 per kg in shell charcoal processing. The results of the calculation of the cost of processing, the results obtained the production cost of charcoal processing is IDR 472.92 per kg, for coconut oil processing is IDR 14,939.13 per kg, and for processing of coconut sugar, it is IDR 8,535.07 per kg. The three products' production cost is far less than the selling price, so the business is quite profitable.

We develop and evaluate the new mini region station in Northern Sumatera for discrimination and feature extract seismic events form shallow and intermediate based on waveforms recorded. Machine learning approaches are employed to classification the waveforms and seismic features of the recoded signal in the time-frequency domain. The most issue of this study are the recurrence of the seismic tremors in January to April 2020 regularly happened, and exceptionally local in Northern Sumatra. This can be also in related to the establishment of modern sensors, for that it will be fundamental to create a high-performance technique for automated clustering of seismic tremors recorded of the modern smaller than expected locale sensors on a limited assortment of floor collectors based on their supply depths. We applied the technique to 25 earthquakes that started January to April 2020, with the depth are smaller than 100 km in the land. A selected set of features were then used to train the system to discriminate from events with a hypo-central depth between 10 to 100 km with 96.01 percent accuracy using the SVM model. The result shows that the spectral feature using wavelet-based with machine learning python (mlpy) package has the highest energy correlation. Wavelet spectral in the time-frequency domain is all-new mini region stations that are promising for seismic event classification. The used machine learning approaches have a good classification of low energy signals recorded at the new mini region station in Northern Sumatera.
Leveraging the 3000 Rice Genome Data for Computational Design of Polymorphic Markers in a Local Rice Variety Lacking Sequence Data
Authors: Satyawan Dani , Warsun Ahmad , Dadang Ahmad , Yunus Muhamad
Published: April 2021

DNA markers can detect DNA sequence variations in the genome, and they are useful for genetic studies, DNA fingerprinting, and genotype-based selection in breeding programs. Rice, as one of the model plants for genetic and genomic studies, has abundant DNA markers stored in various online databases. Selecting markers in rice is not limited by marker availability but rather by their polymorphism in the target population. We developed a computational method to screen millions of single nucleotide polymorphism (SNP) markers listed in IRRI 3000 rice genome database in order to find a subset of markers that are polymorphic in an F2 mapping population created from a cross between a parental line with a known genome sequence and a local Indonesian variety with no genome sequence data. The parental lines were genotyped using an affordable medium-density SNP array. The genotype data was cross-referenced with the rice genome database to perform phylogenetic analysis and identify accessions clusters with the highest genetic similarities to each parental line. The cluster data was then used to identify monomorphic SNP candidates within the cluster but exhibit consistent polymorphism between the two clusters. Using this method, we obtained a SNP marker set for a segment in rice chromosome 8 with 76.19% polymorphism rate, which is much higher than the expected 1.06% polymorphism rate if the SNP markers were chosen randomly. The improved polymorphism rate was also observed when the method was applied to other random chromosome segments and randomly chosen parental candidates.
Numerical-Based Computerized Modelling for Tsunami: Initiating Planning for Natural Disaster of South Kota Denpasar-Bali
Authors: Suartika Gusti Ayu Made , Said Servasius M, , Saputra Kadek Edi
Published: April 2021

This article addresses planning for natural disaster management. It focuses on composing preventive measures before a natural disaster. Assuming a potential tsunami hitting the coast of Sanur (the southern and eastern coastal-fronts of Kota Denpasar - Bali’s capital), analysis is grounded by conducting numerical-based computer modeling. It relies on three sets of data: slope, coefficient of surface roughness, and wave height impact. This computer modeling generates scenarios of potential inundation whose catastrophic consequences would have serious impacts on urban life, individuals, and the island's economy. Based on the height of the wave hitting the coast, three scenarios of 5, 10, and 15 Meters are projected. A numerical-based modeling system provides hypothetical data that is then deterministic in analyzing critically impacted urban areas before any spatial-based evacuation scenario can be developed. The study concludes that Denpasar is potentially in a perilous situation. There is a great and present danger that demands impact-based mitigation planning for natural disasters, which is currently absent. Working with a priority, study findings lead to the most urgent need to constitute a plan for tsunami-based mitigation for Serangan Island - one among ten administrative territories of the selected case study - inundation caused by all three scenarios fully submerge that. However, given Denpasar’s extensive and encompassing littoral zones, the need for such a plan - for all ten spatial units that come under its administration - is now urgent and of maximum priority.
Investigating Suitable Multiple Access Techniques for Harbor Wireless Communication Systems

Published: April 2021

The multiple access communications for harbor environment are suffering from both low quality transmission due many metallic obstacles and overloaded networks due to the huge number of users/devices of logistic monitoring. This paper proposes a coded random access (CRA) scheme with a degree distribution suitable for harbor environment to serve many devices and provide communications with high reliability. The degree distribution is optimized using extrinsic information transfer (EXIT) charts by keeping that two EXIT curves  do not intersect at low mutual information points. Since we are working on the network level, of which the benefit of broadband communications is kept for the fairness with the narrowband transmission, we convert the gain of broadband transmissions into an equivalent gain to the narrowband transmissions based on the Shannon channel capacity and coding theory. We then compare CRA to carrier sense multiple access with collision avoidance (CSMA/CA), because CSMA/CA has better performance compared to other techniques, such as ALOHA and Slotted ALOHA.  We evaluate the performance of the proposed CRA and CSMA/CA using a series of computer simulation in additive white Gaussian noise (AWGN) and multipath Rayleigh fading channels in terms of throughput and packet-loss rate (PLR). The results confirmed that CRA with the proposed degree distribution is more suitable than CSMA/CA as a multiple access technique for harbor wireless communications, indicated that the proposed CRA has higher throughput and lower PLR. The results of this study are expected to contribute to the development of future harbor communication systems.

Published: April 2021

Monitoring Coastline changes is a very important task to assess and evaluate the condition of the coastal area. Accurate results of changes in coastline are very useful as a consideration in making decisions for coastal area management and planning for future coastal development. Therefore, coastline changes, both erosion and accretion were examined in this study. Batu Mejan Beach is selected as a study area. It is a tourism destination often visited by foreign and local tourists in North Kuta Beach. Its current condition is very poor because of the erosion that has occurred. The government has tried to build a sea wall for protection, but the structure has failed. Remote sensing is a method that can monitor shoreline changes more efficiently than taking measurements directly into the field. With the remote sensing method, changes in the shoreline at a certain period can be investigated. The remote sensing analysis method is used to extract coastlines from Landsat 7 satellite images in 2002 and Landsat 8 in 2018. Landsat was analyzed using a combination approach of threshold and band ratio methods of infrared bands and green bands. Image processing uses ENVI 5.3 software and ArcGIS 10.4.1 with the Quoted Shoreline Analysis System (DSAS) extension to make transect shoreline calculations. The results of the analysis of the rate of change in the coastline along Batu Mejan Beach showed abrasion of 0.11-5.14 m/year and accretion of 0.29-0.84 m/year.

Published: April 2021

The current investigation emphasises the expression of candidate genes for the future improvement of fruit quality; the objectives were to describe morphological variation on Solanum caripense Dunal (tzimbalo) ecotypes; identify gene expression of F3H and ANS; and analyse gene expression of C3H. Ecuadorian (BIO) and Peruvian (IBT) samples were utilized. Morphological descriptors for Solanum muricatum Aiton were used; RNA was isolated for identification of F3H and ANS transcripts in BIO-Ltg1 and BIO-Cyb1 through reverse transcription followed by semiquantitative PCR (RT-PCR); C3H relative expression was analysed in IBT-Lib1 for zero, five and fourteen days under influence of controlled conditions (10 ± 2 °C; 16 h day/8 h night) through reverse transcription followed by quantitative PCR (RT-qPCR). The cophenetic correlation (0.88) of conglomerate analysis (CA) pointed out good similarity for Ecuadorian ecotypes and two subgroups for Peruvian ecotypes. The first three principal components (PC) explained qualitatively 71.39% and quantitatively 81.34% of total variation; Fr-Flavour, Se-Diameter, Fl-CorollaColour, Fr-stripes, Fr-Length, Fr-PlacentLength and Fr-PlacentBreadth were characters that contributed more to the variability. The expression of F3H was identified in BIO-Ltg1. The expression of ANS was similar (BIO-Ltg1â†’48.20 ng/µL; BIO-Cyb1â†’36.19 ng/µL). The value of the mean fold change in C3H expression was 3.32, 4.52 and 6.24 for zero, five and fourteen days; C3H transcripts level was significantly different and increased 2.92 units after fourteen days. These results demonstrate the expression of F3H and ANS in BIO-Ltg1 and BIO-Cyb1, differential expression of C3H in IBT-Lib1, and focus the nutritional value of tzimbalo fruit.

Kelok Sembilan flyover is located in West Sumatra-Riau province connection, Indonesia. Landslide occurs along with the connection every year. However, detecting and obtaining scientific information about the potential landslide zone in the area is difficult because it is mountainous, and there is no disaster equipment monitoring installed on it. Here, we identify the area that potential landslide using Satellite Radar SAR Synthetic Aperture Radar) technology with high accuracy until millimeter unit. Also, we showed how to observe the potential landslide with a low penetrate radar signal (C-band) and shifted polarization due to the topography in the vegetation area. The observation data is extracting from satellite Sentinel- 1A/B provided by the European Space Agency (ESA). The satellite is C-band frequency with 5.5 cm wavelength and 5 x 20-meter range-azimuth resolution. The acquisition time of SAR data is starting from October 2014 to August 2018, which is supported by 119 images. Processing the SAR data is using the Quasi-Persistent Scatterer technique to improve the number of scatterers in a non-urban area. Both ascending and descending orbit of the satellite with both VV and VH polarization were selected to confirm potential landslide detection consistency. The result of processing was validated with GPS geodetic by DGPS network configuration. Based on the QPS processing, five areas with significant land movement have been detected; one of them is collapse after ten days since the last data observation. The land movement range in the area is approximately more than 500 millimeters in four years.
M.L. Estimator for Fuzzy Survival Function to the Kidney Failure Patients
Authors: Alnaqash Iftikhar Abd Ulhameed , Abdel Sahib Suha Jafar
Published: April 2021

The dependence of traditional statistical methods in finding estimators and testing hypotheses depends on data that take specific values. However, uncertainty (Fuzzy) appears in most data, including survival time data, which requires researchers to apply Fuzzy methods in general when finding estimators, particularly the estimators of a survival function. In this research, the experimental method (simulation) was used to compare Fuzzy methods (definition of fuzzy logic, cut level -Î´, Buckley) at three fuzzy degrees (0, 0.5, 1), for selected survival times (t = 2, 4, 6, 8, 10, 12) in days. To determine the best fuzzy method used to find the Maximum Likelihood Estimators of the fuzzy survival function depends on the Avery Mean Squares Error (AMES) for the lower and upper bound estimators of the fuzzy survival function for each method. From the experimental method, we came to an advantage of defining fuzzy logic for the maximum likelihood estimator for the survival function of Weibull distribution (distribution of survival times data in the research). The maximum likelihood estimator calculated according to the method of defining fuzzy logic for patients' survival times with kidney failure collected from sections of the dialysis department in educational hospitals (Baghdad, Al-Kindi, Al-Karama, Al-Kadhimiya). This research found that the probability of fuzzy survival for two days to the patients with kidney failure reaches 0.7504 and this probability decreases with an increase in the time of stay until it reaches 0.07704 the probability of staying for a month.
Prioritized Energy-Efficient MAC Protocol in Wireless Sensor Networks
Authors: Park Hyun Joo
Published: April 2021

In this paper, we propose a MAC protocol that provides energy efficiency and QoS for wireless sensor networks. Because it does not classify the data according to the characteristics, traditional MAC protocols for Wireless Sensor Networks cannot provide service differentiations for different traffic classes. For the purpose of QoS support, the input data to the node is divided into priority classes according to the transmission emergency. Depending on the urgency of the data, the protocol can provide time slots for nodes and take different contention window sizes for different traffic classes. Nodes use the reinforcement learning-based control mechanism to actively infer the status of other nodes to classify effectively under various kinds of traffic conditions. The proposed protocol can meet the QoS requirements of delay-sensitive applications and can effectively deal with the problem of a multi-channel hidden terminal with the use of multi-queue. For the next purpose, the proposed protocol is energy efficient because it is based on sleep mode. To improve the energy efficiency, each node has a short non-overlapping listening interval, saving energy in idle listening intervals. This is one of the ways to efficiently use the energy of a node to extend the life of the entire network. This achieves low power consumption by increasing the throughput of data processed across the network and enabling efficient transmission. The classified data can be further improved by rearranging the data according to the nature of the transmitted data in the queue.

This park has bins, lighting, seating, jogging tracks, and other facilities. This study applied the concept formulation approach under a qualitative descriptive method. This study applied a related theoretical foundation technique, either architecture or non-architecture. The data collection was validated for accurate data processing to prepare the concept of planning and design of Taman Samarendah. The planning and design of the Taman Samarendah in Samarinda City with the concept of combining traditional and modern architecture is expected to become a tourist site that has educational value to cultural heritage in terms of architecture and non-architecture and accommodate the Islam worship activities in Samarinda City. The existence and sustainability of traditional houses must be maintained. The traditional houses may disappear faster than we thought. Therefore, further research should review the combination of modern and traditional houses set out in local regulations and laws.

The behavior of reinforced concrete structures depends on sufficient bond strength between concrete and reinforcing steel. The perfect bond between the reinforcement surface and the concrete makes the transfer force work well. In this experiment, several forms of bars overlapped in the concrete and then tested pullout directly. This experiment is to get the tendency of the bond stress patterns that occur in overlapping bars. Another result of the study is the failure pattern of each specimen. The specimen size is 150í—150í—150 mm. In the center of the concrete cube is rib two overlapped bars. The reinforcement used plain and two ribs types of bars surface. The compression of concrete used is a minimum of 25 MPa. Furthermore, the specimen was subjected to a pullout test loaded in stages with 22 kN/minute speed. Loading stopped after the sample has collapsed. The pullout test uses the ASTM C234-91a standard. The failure pattern of plain reinforcement specimens with diameters of 12 mm, 16 mm, and 19 mm is a pullout or a slipped. The specimen with deform bar diameter 13 mm, 16 mm, and 19 mm occurs in splitting failure. The pullout test result, all samples in connection not yielded yet. The results show that the higher the bar diameter's development length, the higher the bond strength. The bond stress of the plain bar is smaller than the deform bar.

Increase in aquaculture activities leads to a negative impact on the environment. Thus, phytoremediation through recirculation aquaculture system becomes one effort that can be applied. The study aimed to evaluate the administration of Echinodorus palaefolius (water jasmine plant) through increasing the capacity of plants as phytoremediators in reducing the waste of intensive culture eel.  This study used a completely randomized design with three treatments of E. palaefolius density and repeated 3 times, as treatments were 1.04 g L-1 (Ep1), 2.08 g L-1 (Ep2), and 3.13 g L-1 (Ep3). The initial average eel weight was 8.3 ± 0.13 g, with a stocking density of 4 g L-1. The results showed a significant difference in the effect of E. palaefolius density on nutrient removal efficiency, as well as performance on eel and plant growth. The highest efficiency of nutrient removal in E. palaefolius with a density of 2.08 g L-1, nitrite (49.65 ± 4.52) %, nitrate (59.62 ± 1.89) %, phosphate (60.88 ± 1. 03) %, and TAN (46.03 ± 0.63) %. At E. palaefolius density 2.08 g L-1 produced eel specific growth rates (0.99 ± 0.02) % lowest feed conversion (1.97 ± 0.03), and highest increase of E. palaefolius biomass (262, 33 ± 2.60 g with daily growth 4.37 ± 0.43 g day-1). Thus, it can be concluded that the density of E. palaefolius 2.08 g L-1 produces the best efficiency in removing nutrients, the growth performance of eels and plants.

Diversity studies in marine ecosystems have experienced many developments with molecular applications through the environmental DNA (eDNA) metabarcoding approach. This method has widely used in identifying rare species, invasive species, and biodiversity information in both freshwater and marine water environments. In this study, the eDNA metabarcoding approach was the first applied to estimate fish diversity surrounding the Pelabuhan Ratu Bay waters. Five liters of seawater samples have been collected from five spots of the surrounding port area. The metabarcoding technique was applied out by using combination DNA barcoding and the next-generation sequencing (NGS) method by MiSeq platform. The MiFish Pipeline for data analyzing to get species estimation and reads numbers for quantifying the fish abundance in this location. DNA successfully identified 20 species, which commercially in the traditional fish market in Pelabuhan Ratu. Then, the eDNA metabarcoding revealed that 44 marine fish species representing 36 genera, 24 families, and ten orders exist in Pelabuhan Ratu Bay's surrounding water. Several marine fish not included in economically but have ecological value in marine fish diversity. Furthermore, fish fall into the category of vulnerable fish (Thunnus obesus), poisonous fish (Acanthurus lineatus, Acanthurus xanthopterus, Siganus vermiculatus, and Siganus fuscescens), and migratory fish. Regular surveys to determine the fluctuations and effects of human activities are necessary to monitor marine diversity, both the effect of over-exploitation and potential pollution from the coastal areas around the Pelabuhan Ratu Bay.
Insurreições estéticas e performances na Amazônia brasileira: notas para uma reflexão decolonial (Edição 485)
Authors: Latif Larissa
Published: April 2021

A crítica decolonial tem, nestas primeiras décadas do século XXI, encontrado expressão entre pesquisadores do campo das artes. Práticas performativas não hegemônicas que acionam múltiplas motrizes culturais revelam a localidade de formas naturalizadas como modelos universais, bem como as potências poéticas e políticas das formas periféricas e híbridas.  Propomos uma reflexão sobre duas formas de teatralidades performativas amazônicas, a corda dos promesseiros do Círio de Nazaré e o movimento das drags themônias, analisados como táticas de desestabilização do sujeito universal moderno e das ordens classificatórias tradicionais da modernidade no que tange à produção das artes da cena na Amazônia brasileira por meio de um desligamento da estética dominante. Articulamos um conjunto de contribuições conceituais do campo dos estudos decoloniais, dos estudos da performance e da crítica transfeminista para refletir sobre as motrizes culturais diversas acionadas na práticas performativas analisadas, constituindo-se corpos que performam na fronteira, na encruzilhada, recriados, redimensionados e ressignificados, capazes de instaurar estéticas e epistemes decoloniais que desafiam as normatividades hegemônicas e o regime de neoescravização do capitalismo avançado.  Palavras-chave: Estéticas decoloniais.

Published: April 2021

Este artigo procura analisar o Sistema Integrado de Gestão de Atividades Acadêmicas (SIGAA), enquanto uma Tecnologia da Informação e Comunicação (TIC), e sua relação com a gestão pública no âmbito organizacional de programas de pós-graduação da Universidade do Pará (UFPA). Para tanto, realizou-se um estudo de caso, com utilização de métodos mistos (qualitativo e quantitativo) no Programa de Pós-Graduação em Gestão de Recursos Naturais e Desenvolvimento Local na Amazônia (PPGEDAM) Núcleo de Meio Ambiente (NUMA), da Universidade Federal do Pará, objetivando investigar a utilidade do SIGAA para o gerenciamento acadêmico e administrativo nesse curso na opinião de docentes, discentes e servidores técnico-administrativos. Os resultados do estudo apontaram que o SIGAA é um sistema que tem se mostrado útil para o gerenciamento acadêmico-administrativo dos cursos, sendo capaz de fornecer dados e informações que contribuem para o processo de tomada de decisão. No entanto, na visão de alguns discentes, o SIGAA tem sido subutilizado, haja vista a resistência de alguns docentes em explorar todas as potencialidades presentes no sistema. Desta forma, sugere-se que haja treinamento constante para todas as categorias de professionais avaliadas e a promulgação de uma política institucional para fortalecer o uso dessa ferramenta tecnológica conforme o mandato PPGEDAM/NUMA, UFPA.Palavras-chave: Tecnologia da Informação e Comunicação (TIC).

Modelagem espacial de vetores sociais em imagens de satélite (Edição 478)
Authors: Sobrinho Sebastião Aluizio Solyno
Published: April 2021

Nesse artigo, desenvolve-se uma metodologia de espacialização de dados sociais e econômicos em imagens de sensoriamento remoto, orientada pelo conceito de trajetórias tecnológicas aplicado em dinâmicas agrárias na Amazônia, tendo por objetivo contribuir com os estudos sobre desmatamento e mudanças no uso da terra. O trabalho se realiza a partir do mapeamento fundiário de uma grande região agrícola no estado do Pará e da integração de estatísticas do Censo Agropecuário do IBGE com imagens do satélite LANDSAT nos anos agrícolas 1995-1996 e 2005-2006. Como resultado, verifica-se que a integração de dados sociais em imagens de sensoriamento remoto possibilita uma leitura mais detalhada da vegetação com a integração dos dados espectrais aos vetores econômicos que determinam a exploração agropecuária. Com isso, concluiu-se que a aplicação do conceito de trajetórias tecnológicas com referência espacial explícita facilita uma maior compreensão das forças motrizes do desmatamento e das mudanças no uso da terra na Amazônia.Palavras-chave: Trajetórias Tecnológicas.
