Authors: Riofrío Juan , Chang Oscar , Revelo-Fuelagán E. J. , Peluffo-Ordóñez Diego H.
Published: June 2020

The Consumer Price Index (CPI) is one of the most important economic indicators for countries’ characterization and is typically considered an official measure of inflation. The CPI considers the monthly price variation of a determined set of goods and services in a specific region, and it is key in the economic and social planning of a given country, hence the great importance of CPI forecasting. In this paper, we outline a comparative study of state-of-the-art predictive models over an Ecuadorian CPI dataset with 174 monthly registers, from 2005 to 2019. This small available dataset makes forecasting a challenging time-series-prediction task. Another difficulty is last year´s trend variation, which since mid-2016, has changed from an upward average of 3.5 points to a stable trend of ±0.8 points. This paper explores the performance of relevant predictive models when tackling the Ecuadorian CPI forecasting problem accurately for the next 12 months. For this, a comparative study considering a variety of predictive models is carried out, including the Neural networks approach using a Sequential Model with Long Short-Term Memory layers machine learning using Support Vector Regression, as well as classical approaches like SARIMA and Exponential Smoothing. We also consider big corporations´ tools like Facebook Prophet. As a result, the paper presents the best predictive models, and parameters found, along with Ecuador´s CPI forecasting for the next 12 months (part of 2020). This information could be used for decision-making in several important topics related to social and economic activities.

Published: June 2020

Knowledge sharing considered an important role in an organization, especially in an organization that focused on research activity such as research organization. Research Organization is an organization that focused on providing scientific information in various forms of collection. The collection often used as a reference for many researchers. The collection saved in the organization library service section and displayed by the types and classified to ease the finding process. In the shelving process, some employees take a different way to do the process besides the shelving procedure and gain new knowledge through experience from it in the form of knowledge. The problem occurred when the turnover of the employee is high because of the job role rotation. It is needed a way to preserve the experience from the previous employee of the shelving process, so when rotation occurred, the learning time of new employees can be reduced. E-learning is one of the solutions that can help the learning process. ADDIE is used as the model for the content of e-learning. The purpose of this research is to design the e-learning content for the shelving process by converting previous tacit knowledge using the SECI method. The output of this paper is the best practice for shelving activity that is used as the content of e-Learning. This research contribution can give a reference on how to convert tacit knowledge into e-learning. Future research can be done to develop the present application by evaluating the weakness and enhancing the feature for improvement.

Published: June 2020

Indonesia is an agricultural country that relies on the agricultural sector and is well known in producing various plantation commodities, one of which is coffee. Coffee is a leading export commodity developed in Indonesia. Community coffee plantations play an important role because most of the coffee production comes from community plantations. However, the condition of community coffee plantations can be said to be still hampered, due to the quality of coffee is still relatively low. It is caused by coffee fruit sorting, which is still done conventionally. The conventional sorting process of coffee fruits is still carried out with the help of operator knowledge, so the level of operator knowledge dramatically influences the results of sorting. The ease of sorting coffee ripeness can be done by implementing a mobile application using digital image processing. Techniques used in digital image processing are the HSV color space to get color features of coffee fruit and the K-Nearest Neighbor (KNN) classification method to classify coffee fruit ripeness. The results of the identification are in the form of ripe, half-ripe, or unripe fruits. The mobile application of this research has two main features, namely training data feature and non real-time identification feature. The results of the testing conducted resulted in an accuracy rate of 95.56% with the best membership value (k) of 3.

Published: June 2020

In the past few years, there has been an increase in natural disasters due to hydrogeological instability caused by heavy rain. Therefore, to reduce the risk of an imminent occurrence of a disastrous event and reduce the risk to humans, an accurate estimate of the precipitation levels based on advanced machine learning techniques is necessary. In this paper, a new dataset is proposed containing audio/video data recorded via a multimodal rain gauge created ad hoc. The dataset, denominated AVDB-4RC (Audio/Video Database for Rainfall Classification), contains digital audio/video sequences recorded for seven different levels of precipitation intensity. In particular, the database presents a set of audio sequences containing the acoustic timbre produced by the rain and video sequences containing rain videos, both in seven different intensities, i.e., “No rain,” “Weak rain,” “Moderate rain,” “Heavy rain” and “Very heavy rain,” "Shower rain" and "Cloudburst rain." For the validation of the dataset, the paper proposes a novel rainfall classification approach based on a video pattern recognition system that uses CNN neural networks. The average classification accuracy is approximately 49% and can reach 75% if the adjacent misclassifications are not considered. Presumably, it is the first open dataset from the new generation acoustic/video rain gauges available for evaluating the estimated rainfall performance. We hope that this new open dataset will encourage a comparison of rainfall estimation/classification algorithms on this common database so that the adopted techniques are objectively assessed and improved.
A New Feature Extraction Method for Classifying Heart Wall from Left Ventricle Cavity
Authors: Sigit Riyanto , Basuki Achmad , Anwar -
Published: June 2020

Echocardiography is a method of examination with high-frequency sound waves to obtain images of heart organs. Examination of heart health conditions with echocardiography as an imaging method, serves to detect the potential for heart disease, thus that the right treatment from the evaluation results can be decided. Examination of the source of heart disease with echocardiography was performed using several views, namely the long axis, short axis, two-chamber, and four-chamber. However, the assessment of cardiac function is still carried out conventionally. Thus it is necessary to build a system that can assess cardiac function. This study proposes a feature extraction method for the classification of heart disease based on the left ventricular motion on the short-axis. In this method, feature extraction uses 24 good features for the process of tracking the movement of the left ventricle with optical flow. Each good feature produces four features, namely direction (negative direction and positive direction) and distance (negative distance and positive distance) from the results of left ventricular tracking and produces 96 attributes for the whole process. The features that have been obtained are then processed using several classification algorithms with validation techniques that are, k-folds, and leave one out. The result is a classification algorithm with a gradient boosting classifier method that has the best accuracy. Gradient boosting classifier produces accuracy values with validation techniques for k-folds 90.98%, and leave one out 93.23%. This shows that the gradient boosting classifier can be relied upon for the classification of heart disease using the proposed feature extraction method. In this study, we developed a new feature extraction method from the results of tracking the heart wall using optical flow. This algorithm can produce feature values from the tracking results that can be used to build a knowledge system for the classification of heart health conditions.

Authors: Marwanto - , Handajaningsih Merakati , Murcitro Bambang Gonggo
Published: June 2020

Coating legume seeds with Rhizobia have met a little success because of the difficulty in supporting bacterial survival on the seed coating agent. Accordingly, these studies aimed (i) to determine the best seed coating formulations to maintain the survival of Rhizobium phaseoli population on the surface of coated bean seed over a storage period of 0, 24, and 48 hours at 400C for laboratory trial, and (ii) to evaluate the best formulations for common bean growth and yield for field trial. Twelve seed coating formulations (SCFs) were used to coat garden bean seeds for the two studies. The results showed that four SCFs were the best for R. phaseoli  survival throughout the storage period. They contained combinations of gum arabic and peat moss (100%), gum arabic and peat moss+biochar (25%:75%), carboxymethyl cellulose and peat moss (100%), and carboxymethyl cellulose and peat moss+biochar (25%:75%). These four Rhizobia seed-coating formulations also promoted the best common bean growth and yield based on nodule number, plant dry weight, and grain yield indicators. Overall, these studies suggest that the four SCFs promoted the highest increase in nodulation, plant biomass production, and grain yield due to their ability to maintain the highest survival of R. phaseoli population on the surface of coated bean seed.

The best treatment for this research is a combination of coconut water at 150 ml/l and 100 g Cavendish banana extract.
Technical Specification for Effective Next Generation Network Interconnection in Indonesia
Authors: Abdurohman Maman , Nugroho Bambang Setia
Published: June 2020

This paper proposes technical specifications for effectively implementing the interconnection of Next Generation Network (NGN) in Indonesia. NGN is one of the current telecommunication infrastructure network technology trends. It provides a simpler concept with only two layers of service and transport. The NGN IP-based transport system can connect with various types of networks, which leads to low management costs by offering different kinds of services. Meanwhile, there are currently various types of telecommunication networks depending on the services provided, such as Public Switched Telephone Network (PSTN), IPv4 Internet as well as Public Switched Data Network (PSDN). PSTN is a circuit-switched voice communications network, and PSDN is a network for data-based communications with International Telecommunication Union (ITU)-T X.121 standards. Another type is a packet-switched based network that uses IPv4 addressing systems. Each network has its customers. One of the problems that arise, however, is how to transform the current network system to the NGN network effectively. The effectiveness of network transformation in the service provision for users is determined by the technical aspects used. Some of the technical aspects issues on implementation of NGN networks in Indonesia are the use of a protocol for signaling, coding standards, Quality of Service (QoS), numbering and addressing, and security. This paper proposes technical specifications for the effectiveness of NGN network implementation in Indonesia. Through the technical specification model, we propose, the risks that will arise in the implementation of NGN networks in Indonesia can be managed. Appropriate technical specifications have an essential role in the effectiveness of NGN network implementation in Indonesia.

Authors: Machado Erica Babini Lapa do Amaral
Published: June 2020

O trabalho discute o paradoxo entre a vanguarda do Estado brasileiro na proteção de direitos humanos e as diversas práticas do sistema de justiça criminal que, oficialmente ou não, violam diametralmente as regras de que é signatário em diversos documentos internacionais. Para tanto, a autora problematiza o conceito de direitos humanos, decorrente de padrões de normatividade americanizada e reducionismos dos destinatários de proteção, apontando para a necessidade de novas revisões que levem em conta a pluralidade de signatários. Também é objeto do debate práticas nacionais do Sistema de Justiça Criminal, as quais são percebidas como herança histórica do autoritarismo (não superado) da sociedade brasileira que resulta no processo de encarceramento em massa. Outrossim, aponta que o cenário de violência urbana associado às sensibilidades culturais fomentam processos sociais de medo e revolta levando a exclusões morais de indivíduos envolvidos no sistema carcerário nacional, repercutindo na indiferença da sociedade civil para a proteção de direitos humanos, o que implica consentimentos para com as práticas de violência, tortura e morte das prisões brasileiras.
Effect of Pre-harvest and Post-harvest Hexanal Treatments on Fruits and Vegetables: A Review
Authors: Ashitha G. N. , Sunny Anjaly C. , Nisha R.
Published: June 2020

The membrane degradation process associated with ripening and senescence of fruit is accelerated by the enzyme phospholipase D (PLD). Hexanal is a compound with high potential to inhibit phospholipase-D enzyme, which is naturally secretes from plants and also promotes the shelf-life extension of fruits during its storage. Pre-harvest hexanal application as enhanced freshness formulation helps to reduce fruit decay and other post-harvest disease by preventing the microbial growth especially mold growth. Post-harvest application of hexanal in the forms of vapour or liquid and nano emulsion for dip treatment, etc. results in improved fruit quality with better colour firmness along with other improved biochemical qualities. The cell wall degrading enzymes such as PLD, PME (Pectin methyl esterase) suppressed after hexanal treatment, whereas accelerated the antioxidant enzymes activities. The hexanal can be used as a potential compound for the preservation and post-harvest storage of perishables with better quality and safety.

Published: June 2020

The present study determined the possible protective effect of pumpkin seed oil (PSO) on cellular apoptosis detection by immunehistochemical method (with (active) caspase-3, -4, 8 and -9 antibodies) in liver tissue and some biochemical parameters; serum ALT activity, vitamin E, plasma 8-OHdG and liver MDA levels, SDH and GPx activities on chronic liver injury induced by carbon tetrachloride (CCl4) in rats. A total of 80 Wistar rats were divided into eight groups of ten rats each: Group I served as control, receiving vehicle 0.9% NaCl (1.0 mL/kg); Group II was given intraperitoneally CCl4 at a dose of 0.2 mL/kg, 1:1 mixture with corn oil, twice a week for 8 weeks. Groups III, IV and V were daily treated with PSO through gavage for 8 weeks (1, 2 and 3 mL/kg, respectively). Groups VI, VII and VIII were administered with intraperitoneally CCl4 (0.2 mL/kg) twice a week and simultaneously PSO by gavage for 8 weeks (1, 2 and 3 mL/kg, respectively). Groups VII and VIII were showed a partial decrease of steatosis in the hepatocytes while the findings in the Group VI were similar to Group II. Compared to Group II, the severity of caspase-3, -8 and -9 activities were not changed in the Group VI but Group VII and VIII were partially reduced. As a result, although no positive effect of 1 mL/kg PSO on liver damage was observed, it has been concluded that PSO has some ameliorative effects by decreasing the levels of biochemical parameters and histopathology in 2 and 3 mL/kg PSO groups. Dose and duration dependent further investigations need to be performed to understand the dose that produces the best result without any side effect.

Published: June 2020

Drought is a major constraint to get an optimum yield of any crop under changing environment. A total of 12 Indian accessions of maize seedlings was screened initially by performing relative water content (RWC) under water deficit condition. Three (RJ-2020, BPCH-6, and EC-3161) landraces that showed a higher RWC than DTSYN11 were finally selected for further studies. Four landraces maintained RWC above 80% under 4th and 8th day stress periods. Higher contents of chlorophyll were recorded significantly in EC-3161 and in RJ-2020 as compared to DTSYN11 under the 8th day of stress. RWC showed a decline in BPCH-6 (72.54%) and in RJ-2020 (72.65%) and proline was significantly increased up to 10 and 13-fold, respectively. Therefore, this research has identified three unfamiliar maize landraces that possess the capacity to be drought tolerance when under water deficit and watering condition. In addition to their useful applications in breeding program, they are valuable resources to elucidate genetic profiling that enhance the capacity to exhibit drought tolerance in Indian maize cultivars.

Published: June 2020

FAO AquaCrop is a simulation model that predicts the effects of soil, climate, water and crop growth on water productivity, yield and its attributes of various crops. In the present study, performance evaluation of AquaCrop model for maize was assessed for rabi maize during 2015 at Water Technology Centre, College of Agriculture, Rajendranagar, Hyderabad. The experiment was laid in a randomized block design with eight treatments in three replications. The treatments comprised of surface and drip irrigation schedules based on Epan viz., surface irrigation at 0.6 IW/CPE ratio (T1), 0.8 IW/CPE ratio (T2), 1.0 IW/CPE ratio (T3), 1.2 IW/CPE ratio (T4), drip irrigation at 0.6 Epan (T5), 0.8 Epan (T6), 1.0 Epan (T7) and 1.2 Epan (T8). The model was evaluated using crop data resulted from the experiment under varying water application methods and levels. Simulation performance was assessed with statistical parameters viz., statistical co-efficient of determination (R2), prediction error (Pe), model efficiency (E), root mean square error (RMSE) and mean absolute error (MAE). The model results are in quite agreement with practical values for grain yield, biomass and water productivity with model efficiency of 0.99, 0.92 and 0.71, coefficient of determination (R2) of 0.90, 0.91 and 0.93 with an RMSE of 0.24, 0.10 and 0.05, respectively. The model prediction errors in simulation of grain yield, biomass and water productivity under all treatments ranged from 1.4% to 11.9%, 1.4% to 16.1% and 4.85% to 25.9%, respectively. The highest and lowest prediction accuracy for grain yield, biomass and water productivity were in drip irrigation at 1.2 Epan and surface irrigation at 0.6 IW/CPE ratios. It is inferred that FAO AquaCrop model is suitable for predicting grain yield, biomass, water productivity and green canopy cover with acceptable range of under and over predictions for maize in semi-arid tropical climate.

Published: June 2020

This experiment was designed to determine the relationship between the antioxidant capacity and the vigour of alfalfa seeds during boron priming. Alfalfa seeds were primed with 1.8 % (W/V) concentration of borax solution for 0, 3, 6, 12 and 24 h at 20°C. The results showed that the vigour of alfalfa seeds declined with the extension of priming time, which was closely related to the accumulation of hydrogen peroxide and malonaldehyde contents and the decrease of superoxide dismutase, catalase and peroxidase. The radicle might be the most sensitive site to boron priming in alfalfa seeds, but the boron-induced damage might be alleviated during alfalfa seeds’ germination.

Published: June 2020

The commercial sexual exploitation of children (CSEC) is considered normative and expected among some Indian castes. Focusing on the Bedia specifically, we sought to identify factors responsible for the intergenerational continuation of CSEC as well as opportunities for prevention. To this end, three questions were posed, including: (a) What structural factors perpetuate CSEC among the Bedia? (b) What are the mechanisms by which Bedia children enter the commercial sex industry (CSI)? and (c) To what extent do Bedia women have personal agency in exiting the CSI and in keeping their children from entering? Guided by structural vulnerability theory and a phenomenological approach, in-depth interviews were conducted with 31 Bedia women engaged in (or exited from) the CSI. Results indicate that girls as young as 12 are “selected” to enter the CSI; once involved, they carry the burden of familial financial sustainability and exit only comes when they are no longer able to attract paying clients and younger female kin able to assume the primary breadwinner role. Ability to keep female children from entry is minimal. Implications for future research, practice, and policy are discussed.

En este trabajo se propone que el dios supremo de los antiguos mayas se concibe dual y a la vez único expresando de esta forma una paradójica unidad de la dualidad. El análisis etimológico e iconográfico, así como la revisión de los mitos y rituales, permite demostrar que d dios supremo expresa la unidad de la realidad que es múltiple pero se reduce a la polaridad de lo húmedo y lo seco, lo femenino y lo masculino, el ciclo y la tierra, etc. En d Ritual de los Bacabs las alusiones sexuales sobre la creación testimonian una hierogamia primordial entre un par de seres divinos que, en última instancia, son uno y el mismo Dios creador. La concidrntiia oppositorum en la concepción maya de la divinidad es clara en la iconografía del dragón bicéfala y en el árbol cocodrilo y juega un papel fundamental en d simbolismo del árbol de las ceremonias de año nuevo. El dios supremo, en su condición de unificador realiza la función de otorgar orden y delimitar ramo el tiempo como el espacio.

En el libro titulado Entre anhelos y recuerdos, de MarieOdile Marion, antropó1oga de sálida presencia y prestigio bien ganado, quien falleció el 17 de junio de 1999, se rescatan los testimonios directos de seis mujeres lacandonas y revela, por la frescura y esponraneidad de sus claros, un mundo poco conocido. La autora, gracias a la gran experiencia y al conocimiento profundo sobre las comunidades indígenas, ubica en su conrexto los pasajes de vida que ella recopiló a través de varias temporadas de campo y luego tradujo, permitiendonos penetrar en esferas y en medios sociales inaccesibles por otra vía, ya que deja que el actor social pueda hablar de su propia experiencia. Las mujeres transmiten los hechos relevantes que se mantienen vivos en su memoria, y sólo por este proceso es posible aprehender una sociedad desde adentro.
Hilos de un mismo tejido cultural: el área maya y la costa del Golfo
Authors: Pérez Suárez Tomás
Published: June 2020

A lo largo de los tiempos prehispánicos el área maya y la Costa del Golfo mantuvieron múltiples y variadas relaciones, evidentes tanto en los materiales arqueológicos como en la distribución de los grupos étnicos que ocupaban ambas áreas culturales. En este trabajo se analizan algunas de estas manifestaciones, con la intención de mostrar que la interacción entre dichas áreas de Mesoamérica fue un fenómeno constante desde el inicio de la vida aldeana hasta el momento del contacto con los conquistadores hispanos y se mantiene induso en la actualidad.

Authors: Ericastilla Samayoa Anna Carla , Jiménez Chacón Lizeth
Published: June 2020

A finales del siglo XIX en la occidental ciudad de Quetzaltenango, Guatemala, las mujeres de las clases subalternas encontraron en la fabricación de aguardiente clandestino una forma de subsistencia que encajaba dentro de los papeles socialmente aceptados. El estudio de esta dinámica contribuye a dar luz a la vida cotidiana de la época y a las relaciones que se registraron entre la población y el Estado liberal, a través de sus autoridades.

La civilización maya ha ejercido una especie de fascinación, continua y creciente, no só1o entre antropólogos, arqueólogos e historiadores, sino en el público en general, interesado por aproximarse a las proezas de los antiguos mayas. Acorde con tal perspectiva, mucha de la investigación inicialmente realizada se preocupaba apenas de determinados aspectos de sus procesos y logros culturales; en particular aquellos que permitían alimentar su fama como artistas, astrónomos, arquitectos, matemáticos y creadores de una escritura que combinaba versatilidad con precisión y gracia. Logros en buena medida posibles merced al clima de paz e igualitaria democracia que, se nos decía, caracterizó su devenir histórico. Hoy, al mismo tiempo que parte de esaperspectiva idílica se ha modificado, gracias en buena medida al avance en el desciframiento epigráfico y a nuevas investigaciones arqueológicas, somos testigos de la recuperación de una nueva escritura de Ia historiamaya que al mismo tiempo que nos ayuda a explicar los distintos derroteros que siguió la treintena de naciones mayances que aun existen, posibilita la forja de una imagen mucho más veraz de estos pueblos. Sin duda los mayas han perdido parte de esa aureola de santos sabios demócratas con que les dotó una abundante literatura de divulgación pseudocientífica y ramplona, pero a cambio de ello se va consolidando una imagen mucho más real y próxima a nosotros, que cancela esa falsa figura de semidioses del panteón indoamericano (cuando no extraterrestres) y hace aparecer a los mayas en toda su compleja, rica y contradictoria humanidad.
José Manuel A. Chávez Gómez, lntención franciscana de evangelizar entre los mayas rebeldes, México, Consejo Nacional para la Cultura y las Artes, 2001
Authors: León Cázares María del Carmen
Published: June 2020

Este libro es el resultado de una investigación documental sobre las actividades de la Orden Serafica entre los grupos mayas insumisos del sur de Campeche, durante el siglo XVII.Se trata de un trabajo original, pues con  la información obtenida del análisis de Fuentes primarias, es decir, en documentos del Archivo General de lndias, del Fondo Franciscano de la Biblioteca Nacional y del Centro de Estudios Históricos de Condumex, el autor estudia y logra relacionar acontecimientos que si en algunmomento habían sido motivo de atención para el historiador franciscano Lino Gómez Canedo, unos, y para los mayistas France Scholes y Ralph Roys otros, no se había planteado tratarlos desde  la perspectiva que aspira a construir una visión de conjunto. Un cuadro donde se integra la descripción de la vida de los indígenas montaraces, replegados tras las fronteras del dominio español, y la explicación de los esfuerzos de cristianizarlos por parte de los franciscanos. Afanes que se manifiestan en la participación de los religiosos en las expediciones que organizan con el propósito de reducirlos, más de una vez contra el parecer de los frailes, colonos y Gobierno de Yucatán, y que culminaran en la fundación de una custodia misionera en territorio rebelde. Objetivo que se propuso Chávez Gómez y cuyos resultadosahora nos ofrece.
The Mayan Franciscan Vocabularies. A preliminary Survey
Authors: Bolles David
Published: June 2020

Este artículo analiza diferentes vocabularios, maya-español y español-maya que los franciscanos de Yucatán escribieron hacia finales del siglo XVI y a lo largo del XVII. Junto con la descripción general de cada uno de esos escritos léxicos, se puso particular atención en fecharlos y, apoyándose en la información existente en las crónicas de Lizana y de López de Cogolludo, se les asignó el autor potencial respectivo. Cuando se descubrieron lazos de parentesco entre esos vocabularios, se examinó también el grado y naturaleza de dicha relación.

Fashion in the information space pseudo creative techniques of attracting the audience are also considered in the article. These are “unbalanced news” that influences the moral and intellectual climate in society, as well as the exploitation of the intention “everything is bad”, which creates anxiety in the perceptions of some young people, disbelief in their own successes, negative perceptions about the country and its future. Mass development of understanding skills in the field of social communication, especially young people, is, according to the author, the important condition main condition for successful processes of socialization and adaptation of modern youth, its ability to resist “meaningful projectiles” of modern information wars.
De um tom apocalíptico adotado há pouco na democracia
Authors: Ruggieri Mariana , Natali Marcos , Pinheiro Tiago Guilherme
Published: June 2020

A longa e múltipla história das relações entre literatura e democracia vem esboçando um novo e tenso capítulo nos últimos anos. Se for verdade que ambas partilham uma confiança pela potência da linguagem para a constituição de formas de interação não excludentes entre diferentes sujeitos e discursos, tal fundamento defronta-se atualmente com um cenário nacional e global descrito frequentemente como colapso ou desastre (seja em rompimento com o estado anterior ou como consequência e exponencialização dele).
