Published: September 2020

Fecundity is essential in the field of population ecology, where the number of eggs is measured to get the actual reproductive rate of an organism. The estimation of fecundity is essential for an accurate study of biology and population dynamics of fish species. This estimation can be developed using the gravimetric method (weight method) to calculate the number of eggs. However, this method still requires experienced technicians and much time and effort to compute the number of eggs manually. The increasing growth in both hardware and software have led to many improvements in imaging technology. Hence, this research addresses the problem of employing constructing a computer vision algorithm. This paper introduced the automatic fecundity estimation method, which applied simple mathematic theories and image processing algorithm to estimate the fecundity of African catfish (Clarias gariepinus). From the image of the fish, the fish’s eye was be detected using a modified Haar Cascade Classifier Algorithm and appointed axis line where the eye becomes the origin point. Next, we identify the region of interest, which reflects the fish's fecundity to obtain the pixels corresponding to the silhouette of the region as coordinates in Euclidean space, which are then represented with a function using cubic interpolation function. Using this function, we compute the region of interest using an integral numerical approach, e.g., Gaussian Quadrature. From the result, we compared with the ground truth to get the estimation of the number of eggs.

Published: September 2020

Fresh-cut tropical fruit is increasingly popular currently, stimulated by public awareness of health and practical lifestyle-fresh-cut fruit presenting consumers' convenience, safety, and quality. Tropical fruit contains functional components that are quite varied and good for health. Mangosteen, Mango, and Rambutan are three exotic tropical fruits that have high economic value and are liked by foreign people. They have a nonedible relatively high and potentially processed into fresh-cut fruit—the process of stripping cutting and slicer, causing wounds that spur damage. During storage, fresh-cut fruits undergo physical-chemical changes—increased respiration rate, ethylene production, oxidation, and browning processes that can shorten shelf life. The damage will be faster if stored at an improper temperature. Fresh-cut fruit is preferably stored at cold temperatures, to extend the shelf life. The research aims to determine the physicochemical characteristics of fresh-cut tropical fruits during cold storage. The research uses a pattern of random group three replicate. The first factor is fruit type (Mango, Mangosteen, Rambutan); the second factor is storage time in cold temperatures (0, 5, 10 days). The variables observed in the study included physical characteristics color (L*a*b*), weight, and texture. Observations of chemical characteristics include moisture content, pH, total acids, vitamin C levels, and total dissolved solids. Fresh-cut tropical fruit has different physicochemical characteristics and experiences deterioration during cold temperatures. The characteristics of tropical fruit have changed significantly on day 5. Mango shows more significant changes than others, seen from variable moisture content, vitamin C, color, and texture. Meanwhile, based on the physicochemical analysis, rigidity of fresh-cut Mango higher than Mangosteen and Rambutan.

Published: September 2020

Seaweed is a strategic commodity in Indonesia. The most cultivated species of seaweed in Indonesia is Eucheuma cottonii. To increase added value, Eucheuma cottonii is processed into various products, including Alkali Treated Cottonii (ATC). ATC is a semi-finished product with high value-added and can be used in both the food and non-food industries. The quality of ATC is strongly influenced by the quality of the seaweed used, which itself is strongly determined by the seed and harvest time of the seaweed. This research aimed to analyze the effect of the seed type and harvest time of seaweed on the quality of the ATC produced. The study was carried out in two stages. The first stage involved cultivating seaweed from different seaweed seeds (Lampung culture and Sumenep culture) and different harvesting times (40, 45, 50 days). The seaweed cultivation was carried out in the waters of Sumenep Regency, East Java, Indonesia. The second stage was to produce ATC from seaweed that had been harvested according to the relevant treatments. This research used a completely randomized design comprising two factors (seaweed seed and harvest time). The quality of seaweed was measured based on the parameters of water content, ash content, sulfate content, and gel strength. The data obtained were processed statistically using ANOVA. The results of the research show that the type of seaweed seed significantly affected the water content, sulfate content, and gel strength but did not significantly affect the ash content. The results also showed that the harvest time significantly affected the water content and gel strength but did not significantly affect the ash content and sulfate content. The best quality seaweed was obtained from the Sumenep type of culture seeds with a harvest time of 40 days after planting. The ATC produced was characterized by an ash content of 13.27%, water level of 13.79%, sulfate content of 1.17%, and gel strength of 1,372.74 gf/cm2.

Published: September 2020

A popular method for time series analysis to extract the components of noise and trend from the time series data is called the singular spectrum analysis (SSA). However, the drawback of SSA is its problem in determining the appropriate window length, L for certain data set in confirming patent separation of the components of trend and noise. Another issue that crops up when using SSA is that, over time, the sum of day-to-day rainfall becomes nearly comparable. In this case, disjoints sets of singular values and distinctive series components could essentially be intermixed, resulting in poor separability between trend and noise components. The introduction of modified SSA is to mitigate the problems efficiently. The performance of modified SSA is measured by using w-correlation and RMSE based on simulated data. These results show that the parameter L = T/5 was suitable to use in short time series rainfall data. It can be proved by the plot of the extracted trend for modified SSA that appears to conform to the original data configuration for time series rainfall however there is the omission of components of noise predominantly for L = T/5 in detecting the uncharacteristically heavy downpour which could potentially initiate the occurrence of torrential rainfall. In addition, the result shows that average RMSE for reconstructed time series components of modified SSA is much smaller than SSA for each L

Published: September 2020

Disaster mitigation in the world of civil engineering can do by improving the performance of construction materials using High-Performance Fiber-Reinforced Concrete (HPFRC). The increasing performance of concrete materials positively affects the physical and mechanical properties of the concrete produced, including the modulus of elasticity. Many equations develop to calculate the distribution of stress-strain of concrete material, such as the Madrid Parabola Formula, Desay & Khrisnan Formula, Majewski Formula, Wang & Hsu Formula, and Saenz Formula. The purpose of this study is to investigate a stress-strain distribution equation and the elastic modulus of elasticity of HPFRC using Portland Pozzolana Cement (PPC) with variations in the composition of silica fume and steel fiber and also investigate the formula of the HPFRC stress-strain distribution. The study conduct using f 15 cm x 30 cm cylindrical specimens. The materials are PPC, sand, gravel, water, silica fume additives, superplasticizers, and Dramix @ 3D steel fiber. Silica fume used varies from 0.0% to 15.0% of the weight of cement. While the steel fiber varies from 0.2% to 1.4% of the volume of the concrete mixture. The compressive strength test carries out refers to ASTM C39/C39M-03, 2003. The stress-strain relationship of HPFRC is obtained from the axial deformation measurement using an extensometer. The results of the study compare with some well-known stress-strain relationship equation. From this study, the stress-strain relationship formula of Desay-Khrisnan is rather suitable for the concrete with W/B ratio variation, but not suitable for silica fume and steel fiber content variation.
Improvement of Trip Attraction Model in Surabaya by Considering Geographical Weighting of City Centre Activity Function
Authors: Herijanto W , Mochtar I B , Wicaksono A
Published: September 2020

It is challenging to have a trip attraction model that fits Surabaya's surveyed data due to unclear city centre structure. These include the centrum of concentric, corridors of sectoral, or several centres of multiple-nuclei structures. Also, the layout of residential areas has unconventional patterns. This is because the planned housing development area is wrongly inserted on kampong and sometimes lies in city centre. This paper examines the influence of single-centre districts, corridors, or multiple suburb centre structures on trip attraction. The analysis was conducted using origin-destination data from the household interview survey by The Transportation Board of Surabaya and several houses digitized from a relevant year's satellite image. The distance and position information was taken from the Google Earth application. The zonal analysis trip attraction model based on the sub-district zoning system was analysed using fixed trip production data and simulated independent variables. The independent variables included the zonal activity areas such as shops, offices, and industries in sub-district, while the dependent variables consisted of the straight distances from the sub-district to city centres. Several models were tested based on the dependent and independent variables. The results show that the combined zonal activity area and spatial variables have a stronger influence on zonal trip attraction than the conventional model using zonal labor and student variable, mainly based on the urban geographical pattern.

Published: September 2020

The Sermo Reservoir plays a vital role in the livelihood of the surrounding community. However, based on the geological map, a fault crosses the reservoir and possibly through the dam body. Therefore, disaster needs to be mitigated by monitoring the deformation of both the fault and the dam body. Deformation monitoring network design needs to consider the accuracy, reliability, and sensitivity in detecting and measuring any displacement. Geological conditions affect the sensitivity of the network. This research aims to analyze the geological structure based on the lineament interpretation of the deformation monitoring network design of the fault. The study was conducted by interpreting lineaments using the Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) image with 30 m resolution and then representing the lineament patterns with a rose diagram. The lineament analysis was related to the rock formation of areas surrounding the Sermo Reservoir. Furthermore, the deformation monitoring network will be designed considering the geological phenomenon resulting from lineament analysis and other factors used in previous research, such as the distance and direction of the control point from the fault. From the lineament analysis, initial information showed that the fault was estimated in the direction of northwest-southeast and may be active. Deformation monitoring stations should be established along the fault plane, in both the right and left sides, and within various distances. The stations should be evenly distributed to cover the areas around the reservoir, the area outside the reservoir but still within the fault area, and the area outside the reservoir and the fault. The distribution of the stations should also form a transverse baseline to the fault.

Published: September 2020

The additive manufacturing (AM) process or three-dimensional printing (3DP) process is making stereoscopic shapes using a layered system. There are several materials used for printing such as plastic, wood, metal as powder, filament, liquid, or others, and there are also different ways for printing. Recently, the focus has been on metal printing, but the problem is that the high energy used such as laser, electron beam, or high heat to melt the metal to print it as required. For this reason, the price of 3D printers for metal is very expensive. In this paper, the design and implementation of a 3D printer for metal parts production are worked. The work also includes making an experimental test for the new 3D printer and printing 3D metal parts without using heat. In this work, Tevo-Tarantula 3D printer has been modified in terms of software and hardware. Two new extruders are designed to inject the metal powder and adhesive, where the heat was removed from the extruder head and the printer bed. The metal powder extruder contains a powder reservoir, glass funnel, and access valve where controlled through the solenoid valve. The adhesive extruder is controlled using a simple hydraulics. The printing process was done by printing two layers of metal powder and a layer of adhesive depending on the desired shape to create 3D objects using the SolidWorks software. Different metal models were printed and these models were compared with the original design which was drawing by SolidWorks software. The difference between the actual model drawing and the printed parts is differences between (0.004 mm) for some parts to (2.3 mm) for other parts or the percentage of error is between (0.1% - 4%) for the printed parts. However, the material can be used in high temperatures, where rubber materials cannot be used, and in applications requiring porosity.

Published: September 2020

One measure of the progress of a nation is the expectancy of inhabitants, especially for the elderly. One of the primary efforts made for the elderly to achieve the quality of life and to remain reasonable is by eating nutritious and diverse foods as well as maintaining nutritional status in a balance condition. The fulfillment of nutritional needs can help in the process of adapting or adjusting to the changes they experienced and can maintain the continuity of body cell changes so that they can prolong life. Generally, support and attention from family members are needed by the elderly, especially in their food consumption. This research applied a qualitative method with a cross-sectional design. This research was conducted in Titi Kuning Village (representing urban areas) and in Ranto Baek Village (representing rural areas). Sampling was carried out using inclusion criteria with the criteria, not dementia, not lying sick, and being able to stretch both hands. Total sampling used in this study, 108 people from the village of Ranto Baek, and 438 people from Titi Kuning village became the sample of this research. As a result of the frequency distribution of urban and rural elder's knowledge about nutritional needs, most urban participants have good knowledge; totally, 251 participants (57.3%) and rural participants have sufficient knowledge, a total of 44 participants (40.7%). The results of the frequency distribution of the urban and rural elderly on eating patterns indicated that both urban and rural participants have a good eating pattern total 282 (64.4%) for urban participants and 85 (77%) for rural participants. In addition, frequency distribution results of the nutritional status of urban and rural elders show that many urban participants have good nutritional status, i.e., 213 (48.6%) and rural participants have heavy weight-loss nutritional status as many as 61 participants (58%). This study found that the knowledge, eating pattern, and nutritional status of participants in the city all were good, whereas the knowledge of the participants in the village was sufficient; the nutritional status was a heavyweight loss, yet the eating pattern was good. The difference between rural and urban communities is due to the influence of participants' insight, the neighborhood, the mass media, and the information available. The results of this study can be a reference for the initial material to conduct further research related to the regulation of balanced nutrition for the elderly.

Published: September 2020

Soon, sociable companion robots will become indispensable for providing related support in our daily living and tasks. This paper provides process, design perspectives, and deployment of a reading companion robot (IQRA’) that monitors the cognitive load level of a reader during demanding reading tasks and to provide support for readers to complete tasks. Current technological solutions only cover external design aspects of the application and have no adaptive mechanisms to deal with dynamics with the reader’s perspectives and environment. Inspired by several theories from cognitive psychology domains, a computational model of the cognitive load was developed as a basis for reasoning and analytical purposes. This analytical ability provides the robot with a computational mechanism to reason in human-like manners and analyses of the functioning of observed conditions. This is essential in providing better-informed actions and intelligent analysis. Besides, the physical and software design of the robot and essential concepts in human-robot interaction are covered. Also, five evaluation constructs were chosen to evaluate the capability of our robot-based platform. These constructs are; 1) likeability, 2) perceived intelligence, 3) sociability, 4) social presence, and 5) cognitive load. The overall results from the pilot study support the practical usage of our proposed robotic solution.

Published: September 2020

Aloe vera L. plants contain various kinds of chemical compounds that are very beneficial for health, so this plant needs to be developed. The limited availability of fertile lands has resulted in the aim of making sandy soil potential for Aloe vera cultivation. The experiment was arranged in a Randomized Complete Block Design with three replications. The first factor was the rate of cow manure, i.e., 30 and 45 t ha-1. The second factor was nitrogen sources of 300 kg ha-1 with 15% addition of humic fertilizer, i.e., urea, AS, NPK, KNO3, humic urea, humic AS, humic NPK, and humic KNO3. The variables measured include water content, protein, fat, carbohydrate, crude fiber, ash, and fresh weight of the leaves. The data were analyzed using analysis of variance at 5% of significance then followed by Duncan’s Multiple Range Test at 5% of significance. The results showed that there was a significant interaction between rates of cow manure and a source of humic nitrogen on all variables. The highest leaf nutrition content was obtained at a rate combination of 30 t ha-1 of cow manure with humic AS, while the carbohydrate content was obtained using a combination of 45 t ha-1 of manure with KNO3 or urea humic acid. The highest growth and yield of the plants was obtained at a combination among 30 t ha-1, manure, and humic urea.

Sobre los predicados de posesión en algunos testamentos nahuas coloniales. Un análisis desde las Tradiciones Discursivas
Authors: Mendoza Posadas Mauro Alberto
Published: September 2020

Sabemos que las lenguas presentan diferentes tipos de relaciones sintácticas para hablar de la posesión de bienes. El náhuatl y el castellano diferían en el siglo XVI en que la estrategia preferida de la primera era un verbo intransitivo, mientras que en la segunda era un verbo transitivo. En esta investigación nos acercamos a la manera en que se representó léxica y sintácticamente la posesión en los documentos testamentarios nahuas del siglo XVI para mostrar la importancia de las Tradiciones Discursivas como locus de cambio lingüístico.

Published: September 2020

The researchers designed and conducted this study using the predictive analytics to determine the different science performance predictors of the first batch of K to 12 curriculum in Valencia District, Valencia, Negros Oriental. The researchers had chosen three kinds of predictors namely; student-related predictors, teacher-related predictors, and school-related predictors. For the student-related predictors, parentsâ€™ educational attainment, parentsâ€™ occupation, family income, IQ level, learning styles and previous grade level science performance. The teacher-related predictors include teachersâ€™ educational qualifications, length of science teaching experience, relevant science trainings and seminars attended, and exposure to access internet connection. On the other hand, the school-related predictors include the type of school, class size, ratio of science books to number of students and conformity of science laboratory equipment and apparatus to K to 12 standards. The researchers had randomly chosen 311 student-respondents and 8 teacher-respondents coming from four public and two private secondary schools of Valencia District. Questionnaires that were tested on its reliability and validity were used in this study. The collected data were then interpreted and analysed using appropriate statistical tools. Studentsâ€™ previous science performance, parentsâ€™ educational attainment, parentsâ€™ occupation, intelligence quotient (IQ), teachersâ€™ educational qualification, number of years in science teaching experience, levels and numbers of seminars and trainings attended and teachersâ€™ internet access significantly predict the level of studentsâ€™ performance in science; thus, they are considered as predictors. However, learning styles, class size, parentsâ€™ occupation, type of school, student-book ratio, and conformity of science equipment and apparatus cannot predict studentsâ€™ level of performance.

Authors: Ugwuanyi Christian Sunday , Okeke Chinedu I.O , Ageda Terpase A
Published: September 2020

Psychological factors like motivation and self-efficacy have been found to have significant predictive powers on learners’ achievement in physics but literature is silent on how gender influences their predictive powers. Based on this premise, the researchers sought the predictive powers of motivation and self-efficacy on physics learners’ achievement based on gender. A correlational survey research design was adopted for the study with a sample of 375 senior secondary 3 physics learners. Learners' Psychological Factors scale was used for data collection. The internal consistency reliability indices of the items of the two clusters of the instrument were obtained as 0.78 and 0.81 using the Cronbach alpha method. Data were analyzed using regression analysis and t-test of independent samples. Results showed that gender had a significant moderating influence on the predictive powers of motivation and self-efficacy on learners' academic achievement in physics in favor of male physics learners. This implies that male physics learners had higher motivation and self-efficacy than their female counterparts, thereby having higher achievement in physics than later. It was recommended that a favorable academic environment should be provided for female learners to promote their motivation and self-efficacy.

Published: September 2020

This study was motivated by the desire to explore the study skills employed by science students in senior high schools (SHS) in the Cape Coast metropolis across the Central Region of Ghana. A total of 600 SHS second-year science students, 354 males, and 244 females, took part in the investigation. The study adopted a cross-sectional survey design. The â€œStudy Skills Scaleâ€ questionnaire was utilised for data collection to determine the kind of study skills employed by the science students, across gender, age range, and school-type. The arithmetic mean was used to establish the degree to which students employ study skills strategies in their learning. Similarly, the consequence of gender, age range, and school-type on the eight subscales of study skills strategies was determined using a one-way multivariate examination of variance. Findings from the investigation indicated that SHS science learners employ study skills strategies in their learning to a large extent for all the subscales of study skills strategies. However, female students employ the memory and concentration study skills strategies more effectively than their male counterparts; demographic variables, such as age range and school-type, do not influence studentsâ€™ study skills significantly. The implications for this study for policy and practice were discussed.

Creation and development process of terms used in music education in Turkey
Authors: Cagirgan Gokhan , Elvan Gun
Published: September 2020

Societies have different ways of transferring the products they created within their own cultural structures by using the basic elements of music. We see that some societies use verbal transfer, some societies use written transfer, while the other societies use both means of transfer. The signs, which are the basis of music theory and the tools of written language, are called "notes", and the text created with these signs is called "musical notation". This study was conducted to examine how music education terms emerged in the historical process, the beginning of using musical notation due to the need for notes among Turkish people, and the creation and development process of terms used in music education in Turkey. For this purpose, the development and dissemination of music theory from past to present were examined by a literature review, and the different opinions and historical information found in the literature were presented together. Also, the introduction of Classical Western Music to Turkish people, their interaction processes, and the changes that occurred regarding the musical sense as a result of the Westernization movements were examined in the study. In this process, particularly the developments in European music had a worldwide influence

Published: September 2020

The aim of this study is to examine the prospective science teachers’ understanding towards entrepreneurial skills. This study, which 146 prospective science teachers of 3rd grade at two state universities in Turkey have participated in, is carried out through the case study method. The data of the research are gathered with “"Entrepreneurial Approach Interview Form (EAIF)”. The acquired data are analyzed by using the content analysis method. It is observed that the relation between entrepreneurship and economy is particularly explained with several characteristics by about one third of prospective teachers, whereas the vast majority of them are unable to establish this relation or give meaningless replies as a result of the research. However, it is found out that the great majority of the prospective teachers are able to explain upon the opportunities of entrepreneurship on the basis of the cultural structure of society. It is seen that very few prospective teachers emphasize on creativity and innovation important in regarding to using entrepreneurial skill. Nevertheless, it is observed that integration of the prospective teachers’ sense of entrepreneurship with technology is inadequate. In addition, it is understood that the vast number of the prospective teachers are incompetent about how they will be able to use the nature and environment when they put their opinions into practice (in the process of business establishment). Moreover, it is revealed that very few candidates are aware of performing the operations such as determining the business idea, making a preliminary assessment of the business idea and questioning the feasibility of the business idea. Furthermore, it is determined that almost all candidates do not have information about the process and content of preparing a business plan. These results show that the prospective science teachers’ understanding towards entrepreneurial skill is quite weak.

Published: September 2020

Abstract

This study aims to develop a scale in order to determine the organisational learning levels of educational organisations. The scale took its final form after the items were written, expertsâ€™ opinions were received and pilot applications were implemented. A survey was administered to 267 teachers using a simple random sampling method. An 18-item organisational learning scale (OLS) was obtained as a result of the exploratory factor analysis. OLS was prepared on the basis of frequency (never-always) to render a possible 5-point Likert type measurement. This 18-item scale was validated by confirmatory factor analyses (CFAs). The factor analyses carried out revealed an 18-item scale with a total of four subscales. These subscales are continuous learning, cognitive processes, transparency and issue orientation. The goodness of fit index values revealed by the results of the CFA carried out indicated that OLS is valid and acceptable. Cronbachâ€™s alpha reliability coefficients of the factors ranged between 0.65 and 0.81. The overall Cronbachâ€™s alpha reliability coefficient of the OLS was determined as 0.85 and its Kaiserâ€“Meyerâ€“Olkin (KMO) value was determined as 0.87. In conclusion, OLS is proposed as a scale based on which the organisational learning levels of schools can be measured in four different subscales.

Principles in selecting children books in primary schools: North Cyprus case
Authors: Oznur Sevket , Sadrazam Ejdan
Published: September 2020

Turkish language went into effect along with the arrival of the Ottomans to the Island in 1571. Since then the Turkish Cypriots have been using Turkish in expressing their customs and traditions and activities. Currently 400.000 people Turkish people on the Island speak, write and broadcast in Turkish. Soon after adapting the use of Latin alphabet by AtatÃ¼rk in Turkey, the Turkish Cypriots began to use the new alphabet as their official language. At present, besides the AtatÃ¼rk Teacher Academy, training primary education teachers, there are eight universities in North Cyprus. In all these institutions there are Turkish Language and Literature, Turkish Teaching departments and Turkish Preparatory Schools for overseas students. In this respect, our aim is to determine the primary school teachersâ€™ (ATA graduates) criterion principles in selecting childrenâ€™s books. The subject question will be dealt with in four sections. The first section includes introduction, under which the problem, aims, significance, numerical data, limitations, and definitions are dealt with. The second section discusses methodology, research model and stages through examples, data collection, analysis, and interpretation. Findings and interpretation will be presented in the third section. The summary, discussion and suggestions will be the scope of the fourth section.

PNEUMATOLOGIA COMO CARACTERÍSTICA DO SER CRISTÃO: A CONTRIBUIÇÃO DO PENTECOSTALISMO AO CONJUNTO DO CRISTIANISMO
Authors: Oliveira David Mesquiati de
Published: September 2020

O propósito desse artigo é mostrar que a pneumatologia pentecostal pode ser uma importante contribuição para as Igrejas, não tanto por seus enun­ciados e práticas específicas, senão pelo lugar central que atribui à experiência do Espírito Santo como experiência de Deus. A pergunta que norteou o estudo foi: que possíveis contribuições a pneumatologia pentecostal oferece ao conjunto de igrejas na atualidade? Para responder a este problema, optou-se por destacar os consensos que se construíram no Ocidente sobre o Espírito, desde os traumas com os grupos espiritualistas, passando pelo “esquecimento” e pela apologética racionalista. Na segunda parte focou-se no específico do pentecostalismo como sujeito teológico para, na terceira parte, efetivamente apontar as possíveis contribuições. Sempre que possível, buscou-se dar voz aos teólogos pentecostais para um diálogo teológico.
O DITO ENIGMÁTICO “EN TOÎS TOÛ PATRÓS MOU” (LC 2,49C): UMA PROPOSTA DE TRADUÇÃO
Authors: Eloi Rodrigues Marcia
Published: September 2020

Este estudo visa contribuir com a discussão acerca da interpretação do dito enigmático “en toîs toû patrós mou”1 (Lc 2,49c) no episódio de Jesus aos doze anos (Lc 2,41-52), mostrando a importância de se ater ao sentido original do texto grego para se obter uma melhor compreensão da intenção comunicativa desse relato. A exposição contempla os principais estudiosos modernos do Evangelho lucano, com indicações de importantes traduções das Bíblias em diversas línguas, e uma breve análise das palavras oîkos e oikía, que correspondem aos vocábulos “casa”, “habitação”, “família” etc. em português, e seu emprego como metáfora da “casa do Pai” (Templo), a fim de descartar essa tradução em favor de outra, mais aberta, a saber: “nas coisas do meu Pai”. Com isso, se pretende fundamentar a hipótese de que Lucas pretendeu escrever um texto ambivalente como estratégia narrativa e comunicativa, em virtude da cooperação do leitor na atualização do texto evangélico. Dessa forma, a narrativa permaneceria com um final “aberto” a ser preenchido pelo leitor ao longo de sua leitura do Evangelho lucano.
CHARACTERISTICS OF INCIDENCE RATE OF COVID-19, ACUTE RESPIRATORY DISEASES, INFLUENZA AND COMMUNITY ACQUIRED PNEUMONIA IN RUSSIA ACCORDING TO CLIMATE, GEOGRAFICAL ASPECTS AND POPULATION DENSITY
Authors: Pshenichnaya Natalia , Lizinfeld Irina , Zhuravlev Grigory

Background: Understanding the impact of geographical aspects and population density on the incidence rate (IR) of respiratory infections in Russia is necessary for successful control under the epidemic.

Aim: to estimate the increase in IR of respiratory infections in 2020 compared to the same period of 2016-2019

Materials and methods: a retrospective study of IR of COVID-19, ARI, influenza and community acquired pneumonia (CAP) in summarily (respiratory infections and COVID-19 morbidity) in the first half of 2020 in comparison with morbidity of ARI, influenza and CAP (respiratory infections morbidity) the same period of 2016-2019 in 85 regions was performed. Additionally the influence of climate on COVID-19 morbidity were estimated.

Results:

The highest excess of respiratory infections and COVID-19 morbidity in 2020 versus the average respiratory infections morbidity in 2016-2019 was observed in Buryatia-107.61%; Zabaykalsky Krai -134.09%; Tuva – 166.34%; the Kaliningrad region – 1023.41%; the Republic of Altai – 1212.78%; Dagestan – 2030.27%.

Buryatia, Tuva, Altai and Zabaykalsky Krai are located next to the China, and also border each other. The Kaliningrad region borders on the EU countries. Dagestan has a maritime border with 3 states, including Iran, where the epidemic COVID-19 began earlier. In 43 of the 85 regions of Russia, this excess was 10-50%; in 35 subjects varied from 50% to 100%.

The correlation between the incidence of COVID-19 and the population density in the regions was weak (r=0.26).

The air pollution, has also a weak relationship (r=0.26) to the incidence rate. Moderate relationship was observed between the severity of negative temperatures in winter and the level of morbidity(r=-0.51). Milder climate probably contributed to the longer persistence of the virus in the environment and social activity.

Conclusion:

Russian regions bordering the PRC, the EU, Central Asia and the Middle East demonstrated the highest IR of influenza, ARI, CAP and COVID-19in summarility in the first part of this year versus the morbidity of influenza, ARI, CAP in average in first half of 2016-2019. IR of COVID-19 has weak correlation with population density and air pollution and moderate negative correlation with winter temperature.

Published: September 2020

Produksi padi dan jagung dapat ditingkatkan melalui optimalisasi lahan dengan pola tumpangsari. Tidak optimalnya produktivitas padi dan jagung dalam pola tanam tumpangsari mungkin disebabkan oleh kombinasi varietas yang kurang tepat. Tujuan penelitian ini adalah mengidentifikasi kombinasi varietas padi dan varietas jagung yang tepat dalam pola tanam tumpangsari, untuk memperoleh produktivitas yang tinggi. Penelitian dilakukan di Desa Durian, Kecamatan Gentuma Raya, Gorontalo, pada MT 2018/2019, menggunakan rancangan acak kelompok factorial, empat ulangan. Faktor pertama adalah varietas padi, yaitu P1 (Inpago-11), P2 (Inpari-42), P3 (Ponelo), dan P4 (Situbagendit). Faktor kedua adalah varietas jagung, yaitu J1 (Bima-20), J2 (NK-22), J3 (HJ-21) dan J4 ((JH-27), ditambah perlakuan padi monokultur dan perlakuan jagung monokultur. Ukuran petak 12,5 m x 12,5 m. Hasil penelitian menunjukkan kombinasi padi varietas Ponelo dan jagung varietas HJ-21 memberikan hasil tertinggi, masing-masing 4,17 t/ha padi dan 8,32 t/ha jagung. Nisbah kesetaraan lahan tertinggi (2,24) dihasilkan dari kombinasi perlakuan tumpangsari padi varietas Ponelo dengan jagung varietas HJ-21. Padi varietas Ponelo adalah varietas local setempat, sehingga diharapkan mudah untuk diadopsi oleh petani.

A atuação profissional do cirurgião-dentista está sujeita ao cumprimento do conceito de responsabilidade civil, já que existe a possibilidade de um paciente acionar judicialmente seu cirurgião-dentista por atos cometidos em sua prática clínica. O presente trabalho teve como objetivo realizar um levantamento dos processos de responsabilidade civil envolvendo cirurgiões-dentistas em três diferentes municípios do interior do estado de São Paulo (Araçatuba, Bauru e Piracicaba), em um período de cinco anos (de 2014 a 2018), a fim de verificar se há crescimento constante da quantidade de demandas judiciais, bem como peculiaridades acerca de indenizações pleiteadas e sentenciadas e sobre a atuação de peritos e assistentes técnicos. Realizou-se uma busca nominal no site do Tribunal de Justiça de São Paulo, onde foi possível ter acesso a essas demandas judiciais. Foram encontrados 33 processos iniciados no período determinado, com uma tendência ao crescimento contínuo em dois dos três municípios analisados, sendo que em apenas cinco das demandas havia sentença promulgada no momento da pesquisa. Por meio da análise descritiva dos documentos, observou-se que, nos municípios analisados, é habitual que valores sentenciados sejam menores do que valores pedidos de indenização em todas as categorias de dano. Quanto à atuação de peritos, nota-se a presença em peso e a importância de sua atuação nesses processos, discordante da quantidade de assistentes técnicos presentes nessas lides

Published: September 2020

The variation in wing morphological features was investigated using geometric morphometric technique of the Sand Fly from two Iraqi provinces Babylon and Diyala . We distributed eleven landmarks on the wings of Sand Fly species. By using the centroid size and shape together, all species were clearly distinguished.  It is clear from these results that the wing analysis is an essential method for future geometric morphometry studies to distinguish the species of Sand Flies in Iraq.

In recent years, there has been expanding development in the vehicular part and the number of vehicles moving on the roads in all the sections of the country. Arabic vehicle number plate identification based on image processing is a dynamic area of this work; this technique is used for security purposes such as tracking of stolen cars and access control to restricted areas. The License Plate Recognition System (LPRS) exploits a digital camera to capture vehicle plate numbers is used as input to the proposed recognition system. Basically, the proposed system consists of three phases, vehicle license plate localization, character segmentation, and character recognition, the License Plate (LP) detection is presented using canny edge detection algorithm, Connect Component Analysis (CCA) have been exploited for segmenting characters. Finally, a Multi-Layer Perceptron Artificial Neural Network (MLPANN) model is utilized to identify and detect the vehicle license plate characters, and hence the results are displayed as a text on GUI. The proposed system successfully detects LP and recognizes multi-style Arabic characters with rates of 96% and 97.872% respectively under different conditions.
El camino al posconflicto: referencias y enseñanzas hacia la paz
Authors: Abella Rodríguez Jorge David , Lesmes Moreno Kevin Andrés
Published: September 2020

La historia colombiana se ha desenvuelto tradicionalmente en compañía de conflictos internos, que han hecho de su desarrollo uno de los más violentos a nivel regional. La constante presencia de grupos subversivos ha impedido el libre despliegue del estado de derecho y la entera presencia del aparato estatal, lo que ha llevado a que la necesidad de terminar con el conflicto armado haya estado presente en las agendas nacionales de los últimos seis periodos presidenciales

Teniendo esto en cuenta, el presente artículo no pretende profundizar en las causas o desarrollo de las cinco décadas de confrontación armada que parecen estar por terminar, sino con una tónica constructivista, esbozar los principales retos macroeconómicos que Colombia debe afrontar en esta nueva etapa de su historia.
