Rabies is an infectious disease, zoonotic, caused by virus from the genus Lyssa virus and generally transmitted by the bite of rabid animal, especially rabies infected dog. Rabies is preventable but is always fatal to humans if the central nervous system (CNS) is infected. Vaccination has been used as one of rabies prevention programmed. A total of 83 samples were tested using an Indirect ELISA (Enzyme Linked Immunosorbent Assay) to identify post-vaccination rabies antibody titer. Antibody titres correlated with absorbance values and standard solutions concentrations. Absorbance value can be determined using ELISA reader and mobile phone camera. Absorbance were read at 450 nm and 620 nm as reference using ELISA reader and image from mobile phone camera using image processing software (ImageJ). The aim of this study is to compared between ELISA reader as gold standard and mobile phone camera through validity testing such sensitivity, specificity, and accuracy. There is no significant difference between gold standard and alternative test equipment. The mobile phone camera has sensitivity 98,6%, specificity 88.8 % and accuracy 97,5%. The image processing method using ELISA reader is relatively expensive and difficult to hold in laboratory with minimum funds. Image processing method using a mobile phone camera with ImageJ application is expected to be an alternative tool to read the result of ELISA.

From «Revolution» to «Transformations» and «Changes»? Development of Discourses of Analysis Qualitative Social Change
Authors: Latov Yury
Published: March 2021

The popular condemnation of «revolutionaryism» in post-Soviet Russia is seen as contradicting the global trends in scientific analysis of the role of revolutions in the development of society, according to which it is the revolutionary institutional changes that are most important for social progress. These ideas were first comprehensively expressed by the founders of Marxism, and in the twentieth century. in Western sociological thought «completed», on the one hand, with the theories of the scientific and technological revolution, on the other hand, with the concepts of the sociology of revolution. The desire of Russian social scientists to overcome the legacy of Soviet «forced Marxism» led to a conscious alienation from the post-Marxist sociology of revolution. In Russian scientific discourse in the 1990s–2000s. there was a displacement of the discussion of revolutionary changes by using less specific concepts of «social transformation» and «change», and in the 2010s. it joined with the government’s policy of a fundamental rejection of any revolutionary changes. As a result, Russian sociologists lose the ability to distinguish between revolutionary and evolutionary shifts in the development of Russian society, focusing mainly on their traumatic nature.

Published: March 2021

Jember Regency is one of the agro-industrial areas in Indonesia with a variety of activities that can produce noise including milling industry. Exposure to noise that is too strong or too long will damage the auditory nerve. The type of material being grounded determines the amount of noise produced so that the potential for hearing nerve damage also varies. This study aims to determine the level of noise produced by the milling industry and analyze the potential for hearing nerve damage in milling workers in Jember Regency. This type of research is observational analytic with cross-sectional approach. This research was conducted by measuring noise in several grinding locations in Jember that were randomly determined. Types of careful milling is grinding meat, coffee, rice, sticky rice and coconut. In addition to measuring the noise level, a short interview was also conducted with the mill workers regarding how long they worked at the mill every day. The measurement results are then analyzed descriptively and compared with standards set by the government and the Occupational Safety and Health Administration (OSHA). In this study it was found that the grinding of meat raw materials produced an average noise level of 88.5 db, coffee of 88.5 db, rice of 88.9 db, sticky rice of 87.3 db and coconut of 80.7 db. The duration of exposure to noise in milling meat, coffee, rice and sticky rice ranges from 9-12 hours a day. While the duration of noise exposure to coconut milling workers ranged from 6-9 hours. Therefore it can be concluded that milling meat, coffee, rice and sticky rice has the potential to cause hearing loss for workers.

Published: March 2021

Bercak darah dapat ditemukan di tempat kejadian perkara (TKP) pada banyak kasus tindak kekerasan. Asam deoksiribonukleat (DNA) pada darah dapat digunakan sebagai data primer untuk proses identifikasi akan tetapi bercak darah di TKP berisiko rusak akibat pajanan tanah dan ultraviolet. Tujuan utama dari penelitian ini adalah untuk mempelajari efek kombinasi dari pajanan sinar ultraviolet-C dan tanah terhadap kualitas dan kuantitas DNA pada bercak darah. Sebanyak 20 gelas berisi 200 gram tanah ditetesi 900µl darah dan diberikan pajanan sinar ultraviolet-C dalam tiga kelompok berdasarkan durasi pajanan yakni satu hari, tiga hari, dan lima hari. Satu kelompok digunakan sebagai kontrol. Ekstraksi DNA dilakukan menggunakan DNAZol dilanjutkan dengan pengukuran spektrofotometri untuk mengetahui kualitas dan kuantitas DNA. Peningkatan konsentrasi DNA dapat diamati yaitu 681,1 pada hari pertama menjadi 1274,7 pada hari ketiga dan mulai menurun menjadi 1090,6 pada hari kelima, sedangkan kemurnian DNA terus menurun secara konstan seiring dengan meningkatnya durasi pajanan. Penelitian ini menunjukkan bahwa pajanan sinar ultraviolet-C dan tanah menyebabkan degradasi molekul DNA menjadi fragmen-fragmen molekul yang lebih kecil sehingga terjadi peningkatan kuantitas DNA yang disertai penurunan kualitas DNA. Penurunan kualitas DNA dapat mempersulit proses identifikasi sehingga isolasi DNA sampel pada tanah terbuka yang terpajan matahari harus dilakukan sesegera mungkin.

Uplink IoT Networks: Time-Division Priority-Based Non-Orthogonal Multiple Access Approach
Authors: M. Elhalawany Basem , A.Aziz El-Banna Ahmad , Wu Kaishun , Khan Wali Ullah
Published: March 2021

Non-orthogonal multiple access (NOMA) has been investigated to support massive connectivity for Internet-of-things (IoT) networks. However, since most IoT devices suffer from limited power and decoding capabilities, it is not desirable to pair a large number of devices simultaneously, which encourages two-user NOMA grouping. Additionally, most existing techniques have not considered the diversity in the target QoS of IoT devices, which may lead to spectrum inefficiency. Few investigations have partially considered that issue by using an order-based power allocation (OPA) approach, where the power is allocated according to the order to the user's target throughput within a priority-based NOMA (PNOMA) group. However, this does not fully capture the effects of diversity in the values of the users' target throughputs. In this work, we handle both problems by considering a throughput-based power allocation (TPA) approach, that captures the QoS diversity, within a three-users PNOMA group as a compromise between spectral efficiency and complexity. Specifically, we investigate the performance of a time-division PNOMA (TD-PNOMA) scheme, where the transmission time is divided into two-time slots with two-users per PNOMA group. The performance of such TD-PNOMA is compared with a fully PNOMA (F-PNOMA) scheme, where the three users share the whole transmission time, in terms of the ergodic capacity under imperfect successive interference cancellation (SIC). The results reveal the superiority of TPA compared with OPA approach in both schemes, besides that the throughput of both schemes can outperform each other under imperfect SIC based on the transmit signal-to-noise ratio and the deployment scenarios.
Non-Invasive Evaluation of Acute Effects of Tubulin Binding Agents: A Review of Imaging Vascular Disruption in Tumors

Published: March 2021

Tumor vasculature proliferates rapidly, generally lacks pericyte coverage, and is uniquely frag-ile making it an attractive therapeutic target. A subset of small-molecule tubulin binding agents cause disaggregation of the endothelial cytoskeleton leading to enhanced vascular permeability generating increased interstitial pressure. The resulting vascular collapse and ischemia cause downstream hypoxia, ultimately leading to cell death and necrosis. Thus, local damage gener-ates massive amplification and tumor destruction. The tumor vasculature is readily accessed and potentially a common target irrespective of disease site in the body. Development of a therapeutic approach and particularly next generation agents benefits from effective non-invasive assays. Imaging technologies offer varying degrees of sophistication and ease of implementation. This review considers technological strengths and weaknesses with examples from our own laboratory. Methods reveal vascular extent and patency, as well as insights into tissue viability, proliferation and necrosis. Spatiotemporal resolution ranges from cellular mi-croscopy to single slice tomography and full three-dimensional views of whole tumors and measurements can be sufficiently rapid to reveal acute changes or long-term outcomes. Since imaging is non-invasive, each tumor may serve as its own control making investigations par-ticularly efficient and rigorous. The concept of tumor vascular disruption was proposed over 30 years ago and it remains an active area of research.

Published: March 2021

Abstract Background: Premature babies have a greater risk for having health issues after being discharged from the hospital whilst the mother ability to provide premature baby care still has many issues as well. Interventions are needed to be given to mothers at home to improve the ability of mothers to care their premature babies. Methods: Search for articles used the bolean operator of “or” and “and” with the keywords used were “preterm or premature”, “intervention or program”, and “mother and home”. Data based used were Sciencedirect, Ebscohost, PubMed, SAGE, Proquest and Scopus with inclusion criteria using full text in English from 2018 to 2021. There were 428 articles obtained, the articles were then screened by reading the main focus of articles with paying attention to the topic and the suitability of article content and we obtained 13 suitable articles. Results: The interventions at home carried out for mothers and premature babies were divided into two namely the follow-up interventions from the hospital and the interventions carried out at the patient's home. Seven articles about research of interventions that were as a combination from hospital intervention with follow-up hospital intervention plus five full interventions at the patient's home. Interventions were provided through home visits (12 articles) and by telephone (1 article). The results of the article analysis resulted in 4 main themes of intervention for mothers and premature babies, they were health education, counceling, support, and care for premature babies. Conclusion: Quality care is essential for the best health, growth and development of premature babies. Interventions need to be carried out by health workers to ensure the readiness and ability of mothers to care for their babies. Maternal readiness and abilities can be improved by providing health education, counseling, support and care for premature babies.
Stability of the Glutathione Supplementation into Parenteral Nutrition to Protect Very Preterm Babies from Oxidative Stress
Authors: Guiraut Clémence , El Raichani Nadine , Morin Guillaume , Mohamed Ibrahim , Lavoie Jean-Claude
Published: March 2021

Most very premature newborns (< 32 weeks of gestation) receive parenteral nutrition (PN) that is inherently contaminated with peroxides. Oxidative stress induced by PN is associated with bronchopulmonary dysplasia, a main pathological complication in these babies who have weak antioxidant capacity to detoxify peroxides because of their glutathione deficiency. In animals, glutathione supplementation of PN prevented oxidative stress and alveolar loss (the main characteristic of bronchopulmonary dysplasia). Of its two forms - disulfide (GSSG) and free thiol (GSH) - GSSG was used because of its better stability in PN. However, a 30% loss of GSSG in PN is observed. The potentially high therapeutic benefits of GSSG supplementation on the health of very premature babies makes the study of its stability highly important. Thus, GSSG was incubated in combination with the following components of PN: dextrose, multivitamins, Primene, Travasol, as well as with cysteine, cystine and peroxides for 24h. Total glutathione in these solutions was measured 0-24h after the addition of GSSG. The combination of cysteine and multivitamins caused the maximum loss of glutathione. Removing the cysteine prevented the degradation of glutathione. GSSG reacts with cysteine to form cysteine-glutathione disulfide, another suitable glutathione substrate for preterm neonates.

Forty-eight conditions are created in Monte Carlo (MC) simulation for the data, generated in R software, including 500 items and 5000 examinees, and the results are calculated over 30 replications. As a result of the study, it was observed that CI performs better in terms of ATL, and SPRT performs better in ACA and correlation, bias, Root Mean Squared Error (RMSE), and Mean Absolute Error (MAE) values, sequentially; MFI-EB is more useful than MFI-CB. It was also seen that MMM is more successful in content balancing, whereas CCAT is better in terms of test efficiency (ATL and ACA), and IE is superior in terms of item exposure control though SH is more beneficial in test efficiency. Besides, increasing the number of classification categories increases ATL but decreases ACA, and it gives better results in terms of the correlation, bias, RMSE, and MAE values.
How Reliable Is It to Automatically Score Open-Ended Items? An Application in the Turkish Language
Authors: UYSAL İbrahim , DOĞAN Nuri
Published: March 2021

The use of open-ended items, especially in large-scale tests, created difficulties in scoring open-ended items. However, this problem can be overcome with an approach based on automated scoring of open-ended items. The aim of this study was to examine the reliability of the data obtained by scoring open-ended items automatically. One of the objectives was to compare different algorithms based on machine learning in automated scoring (support vector machines, logistic regression, multinominal Naive Bayes, long-short term memory, and bidirectional long-short term memory). The other objective was to investigate the change in the reliability of automated scoring by differentiating the data rate used in testing the automated scoring system (33%, 20%, and 10%). While examining the reliability of automated scoring, a comparison was made with the reliability of the data obtained from human raters. In this study, which demonstrated the first automated scoring attempt of open-ended items in the Turkish language, Turkish test data of the Academic Skills Monitoring and Evaluation (ABIDE) program administered by the Ministry of National Education were used. Cross-validation was used to test the system. Regarding the coefficients of agreement to show reliability, the percentage of agreement, the quadratic-weighted Kappa, which is frequently used in automated scoring studies, and the Gwet's AC1 coefficient, which is not affected by the prevalence problem in the distribution of data into categories, were used. The results of the study showed that automated scoring algorithms could be utilized. It was found that the best algorithm to be used in automated scoring is bidirectional long-short term memory. Long-short term memory and multinominal Naive Bayes algorithms showed lower performance than support vector machines, logistic regression, and bidirectional long-short term memory algorithms. In automated scoring, it was determined that the coefficients of agreement at 33% test data rate were slightly lower comparing 10% and 20% test data rates, but were within the desired range.

Authors: Oro Hershtein Lucas
Published: March 2021

En el Libro de las Fuentes (Kitāb al-Yanābīʿ), Abū Yaʿqūb al-Sijistānī propone una fundamentación teórica para la Ismāʿīliyyah, un colectivo religioso que se expresa simultáneamente como un movimiento político. Este artículo, destinado a un lector que se inicia en el tema, intenta mostrar que la filosofía política que la obra despliega nace en el ángulo donde se superponen la visión sincrónica de una metafísica de raíz neoplatónica y la visión diacrónica de una profetología de raíz ismāʿīlī.
Towards a New Methodology for Natural Philosophy: Latin Averroism Revisited
Authors: Herráiz Oliva Pilar
Published: March 2021

The reception of Aristotelian philosophy with Averroes’s commentaries in the thirteenth-century Latin world promoted a new way of understanding natural philosophy and its method. A very special case among the readers of such commentaries, mostly found at the Faculty of Arts of the University of Paris, are the so-called averroistae. What these averroistae actually were is still a matter of discussion in current scholarship, whereas there is kind of consensus regarding the main exponents of this philosophical movement, namely Siger of Brabant and Boethius of Dacia. The aim of this paper is to shed light on this topic by providing a re-definition of Averroism in the 13th century. To do this, I will analyse some of the most important works of the aforementioned authors in an attempt to clarify the specificity of their philosophical program.

This study aims to analyze the impact of Information and Communication Technology (ICT) on bilateral trade in service between Indonesia and its ASEAN trading partners. The sample is bilateral export in service between Indonesia and 9 ASEAN countries such as Malaysia, Philippines, Singapore, Thailand, Brunei Darussalam, Vietnam, Myanmar, Laos and Cambodia. The total trade in service data is based on UN-Comtrade. It consists of service products that are coded in Standard International Trade Classification (SITC). This study uses the gravity model framework of data panel from 2005 to 2017 with random effect model is analyzed using Generalized Least Square. Based on the regression analysis, results show that sub-index of ICT Development Index (IDI) such as mobile-cellular telephone subscriptions per 100 inhabitants which represents technology development, has a positive and significant impact on Indonesia’s service export to ASEAN countries. Other variables such as GDP and distance also have significant effect on Indonesia’s export in service. GDP reporter, GDP partners and common language have positive and significant effect on Indonesia’s export in service. Furthermore, distance has a negative and significant effect on Indonesia’s export in service. These results are in line with Gravity model theory. In addition, these results are expected to be strong enough for the specifications of alternative models and estimation methods. Based on these results, some expected trade policy recommendation related to trade in service and telecommunication particularly trade between Indonesia and ASEAN countries can be formulated. For instance, to strengthen Indonesia’s networking and infrastructure of telecommunication in ASEAN countries. To build more Base Transceiver Station (BTS) located in trading partners in ASEAN. Telin Singapore established by Telkom Indonesia is officially established in 2007 and is the first Telkom footprint in international business. Since Singapore is Indonesia’s trading partner which has the highest of ICT Development Index among other ASEAN countries, the Indonesian government need to continue the implementation of Information and Communication Joint Committee Indonesia-Singapore.

Sectoral economic growth affects the level of poverty in the area. High economic growth does not merely reduce poverty. Equitable distribution of income is also a matter that needs to be considered in line with increased economic growth. High economic growth is the process of accumulation of sectoral economic growth that has undergone a structural shift in its journey. Changes in economic structure are marked by a decrease in the contribution of the agricultural sector and an increase in the contribution of the industrial sector, both in gross domestic product (GDP) and in employment. Economic growth needs to be directed towards economic sectors that are effective in reducing poverty and creating equitable distribution of income. The purpose of this study is to answer the question of how the influence of sectoral economic growth on poverty in East Java. For this purpose the panel data regression model is used. The selection of variables is based on research objectives. Agriculture sector GRDP (VP), industrial sector GRDP (VI) and service sector GRDP (VJ) represent sectoral economic growth. The results of the test show an increase in the contribution of the industrial sector effectively reduces poverty. In other words, between the agriculture, industry and services sectors, only the industrial sector has positive and significant parameters for poverty in East Java.
Implikasi Kebijakan Perdagangan ACFTA Pada Bawang Putih Impor di Indonesia: Model Permintaan Impor
Authors: Yovirizka Inggarani Ulfa , Haryanto Tri
Published: March 2021

Indonesia is the biggest importer of garlic in the world. Each country has a trade policy to control imports, and Indonesia is implementing a free trade agreement, namely ACFTA. The purpose of this study was to analyze the effect of the ACFTA trade policy on Indonesian garlic using the import demand model. The method in this study uses the Eagle-Granger cointegration test and error correction model (ECM). Stationary test results using augmented Dickey-Fuller indicate that each stationary variable at the first difference level. Cointegration test shows that import variables, per capita income, relative prices, production and consumption ratios, and dummy have a long-term balance. The relative price, the ratio of production and consumption, and the dummy have a significant effect on the demand for imported garlic in the long run. In the short term, import demand is affected by the ratio of production and consumption, and dummy tariffs.

Purpose: To assess whether positive flow cytometry quantification of fetal red blood cells is associated with adverse outcomes in cases of trauma during pregnancy.Methods: A retrospective cohort study, at a single tertiary center between 2013 and 2019. All pregnant women with viable gestation involved in trauma who underwent flow cytometry were included. Flow cytometry was considered positive (≥0.03/≥30 ml). Composite adverse maternal and neonatal outcomes were compared between cases with positive and negative flow cytometry test. Univariate and multivariate logistic regression analysis were performed to assess the role of flow cytometry in predicting adverse outcomes. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated.Results: During the study 1023 women met inclusion and exclusion criteria. The mechanisms of injury were motor vehicle accident in 387 women (38%), falls in 367 (36%), direct abdominal trauma in 353 (35%) and in 14 women (1%) other mechanism of injury. Among the cohort, 119 women (11.6%) had positive flow cytometry (≥0.03/≥30 ml) with median result of 0.03 [0.03-0.04], while 904 women (88.4%) had negative flow cytometry test result (≤0.03/≤30 ml) with median result of 0.01 [0.01-0.02]. Composite adverse outcome occurred in 8% of the women, with no difference in the groups with vs. without positive flow cytometry (4.2% vs. 8.5%; p=0.1). Positive flow cytometry was not associated with any adverse maternal or neonatal outcome. This was confirmed on a multivariate analysis. Conclusions: Flow cytometry result is not related to adverse maternal and fetal/neonatal outcome of women involved in minor trauma during pregnancy. We suggest that flow cytometry should not be routinely assessed in pregnant women involved in minor trauma.

Purpose: To identify the pitfalls in retinopathy of prematurity (ROP) screening leading to advanced disease at Ministry of Health (MOH) hospitals in Saudi Arabia. Methods: A qualitative deductive content analysis was used to study the phenomena of defects in ROP screening. A retrospective review of medical records of newborns presenting to two tertiary eye care centers with advanced ROP (Stage 4 and 5) from January 2012 to June 2019 was completed. An extensive review of the original files at the referring hospitals was conducted, including the general condition and findings of ophthalmic examination and the sequence of follow-up until the infant was discharged/referred. Data analysis was completed using pre-structured categorization matrix. Results: Records of 29 infants with advanced stage ROP were identified. Only 13 medical records were available and obtained. The pitfalls in screening found in the study were failure to refer by the neonatologist, delayed follow-up by the ophthalmologist, failure to follow-up by the ophthalmologist, failure to diagnose by the ophthalmologist, poor documentation in patient files, unavailability of ophthalmologist, family negligence, lack of treatment and delayed referral to a higher center, and progression despite timely screening and management.Conclusion: Although clear ROP screening guidelines are available, implementations of these guidelines are suboptimal. This study showed the most common defect in screening is physician’s inadequacy and unavailability. A proper network of competent ROP screening physicians in all neonatal intensive care units should be established. Centers for advanced ROP surgery should be allocated to deliver a timely surgical care if needed.
