Authors: Sopandi Wahyu
Published: May 2019

This study investigated the impact of socialization and workshops about the Read- Answer-Discuss-Explain-and Create (RADEC) learning model on teacher readiness to implement it. The investigation involved 92 teachers (elementary school, middle school, and high school teachers). The research instrument was a questionnaire consisting of two parts. The first part questionnaire was given before the activity and was intended to reveal the experience of the teachers to implement currently familiar innovative learning models. The second part questionnaire was given after the activity and was intended to reveal the teachers' readiness to implement the RADEC learning model. Data were processed quantitatively and qualitatively. The research results of the first questionnaire show that teachers had not been able to implement currently familiar innovative learning models for various reasons. The research results of the second indicate that the social- ization and workshop can prepare teachers to implement the RADEC learning model. This can be seen from the majority of those who argue that (1) the syntax of the RADEC learning model is easy to remember and understand; (2) the RADEC learning model can practice 21st century skills; and (3) they are interested in researching the implementation of the RADEC learning model.

Authors: Zou Ming , Zhang Yi , Huang Xi , Gao Sheng , Zhang Junjun
Published: May 2019

Background

To evaluate the etiology, demographic profile, clinical features, and outcomes in patients with peripapillary subretinal hemorrhage (PSH).

Methods

Thirty-eight eyes of 37 consecutive patients with PSH were enrolled in this prospective observational study over 4 years; all were followed for 2 years. The main outcome measures were demographic profile, possible etiology, clinical features, outcome, and prognosis.

Results

Sixty-eight percent (26/38) of eyes were in female patients; the mean patient age was 20 years. Only 1 patient (1/37) showed bilateral involvement. All patients experienced acute onset of PSH. All eyes were myopic and their best-corrected visual acuities ranged from 20/1000 to 20/12.5. The fundus features of affected eyes were classified into 3 groups: (1) PSH alone (4/38 eyes, 10.5%); (2) PSH with intrapapillary hemorrhage (17/38 eyes, 44.7%); (3) PSH with intrapapillary and vitreous hemorrhage (17/38 eyes, 44.7%). PSH occurred in nasal edges of optic discs with a crescent shape and dull-red color. All affected optic discs were small and crowded, exhibiting variable degrees of tilting. The cup of affected optic discs was narrower and deeper than that of normal control discs. Other ancillary tests provided no additional value. After a mean follow-up of 2.85 months, the hemorrhages resolved spontaneously without sequelae. Recurrence of disease was not observed in any patients.

Conclusions

PSH is common in myopic eyes with tilted optic discs. We suspect that these hemorrhages occurred as a result of abrupt movement acting on a morphologically vulnerable optic disc.

Published: May 2019

Background: To evaluate the retinal function before and soon after an intravitreal injection of an anti-vascular endothelial growth factor (anti-VEGF) agents.
Methods: Seventy-nine eyes of 79 patients that were treated by an intravitreal injection of an anti-VEGF agent for age-related macular degeneration (AMD), diabetic macular edema (DME), or retinal vein occlusion (RVO) with macular edema (ME) were studied. The RETeval® system was used to record 28 Hz flicker electroretinograms (ERGs) from the injected and non-injected eyes before (Phase 1, P1), within 2 hours after the injection (P2), and 2 to 24 hours after the injection (P3). Patients were grouped by disease or by the injected agent and compared. The significance of the changes in the implicit times and amplitudes was determined by t tests.
Results:
The amplitudes were not significantly different at the three phases. The implicit time of the injected eye was 31.2±3.2 msec at P1, and it was not significantly different at P2 (31.7±3.1 msec) but it was significantly longer at P3 (32.2±3.3 msec, P<0.01, ANOVA for both). The implicit time in the non-injected fellow eye was 30.5±3.3 msec at P1, and it was significantly longer at P2 (31.1±3.2 msec) and phase 3 (31.3±3.4 msec, P<0.01, ANOVA for both).
Conclusions: The results indicate that an intravitreal anti-VEGF injection will increase the implicit times not only in the injected eye but also in the non-injected eye soon after the intravitreal injection.

Published: May 2019

Background

With the diabetes mellitus (DM) prevalence increasing annually, the human grading of retinal images to evaluate DR has posed a substantial burden worldwide. SmartEye is a recently developed fundus image processing and analysis system with lesion quantification function for DR screening. It is sensitive to the lesion area and can automatically identify the lesion position and size. We reported the diabetic retinopathy (DR) grading results of SmartEye versus ophthalmologists in analyzing images captured with non-mydriatic fundus cameras in community healthcare centers, as well as DR lesion quantitative analysis results on different disease stages.

Methods

This is a cross-sectional study. All the fundus images were collected from the Shanghai Diabetic Eye Study in Diabetics (SDES) program from Apr 2016 to Aug 2017. 19904 fundus images were acquired from 6013 diabetic patients. The grading results of ophthalmologists and SmartEye are compared. Lesion quantification of several images at different DR stages is also presented.

Results

The sensitivity for diagnosing no DR, mild NPDR (non-proliferative diabetic retinopathy), moderate NPDR, severe NPDR, PDR (proliferative diabetic retinopathy) are 86.19%, 83.18%, 88.64%, 89.59%, and 85.02%. The specificity are 63.07%, 70.96%, 64.16%, 70.38%, and 74.79%, respectively. The AUC are PDR, 0.80 (0.79, 0.81); severe NPDR, 0.80 (0.79, 0.80); moderate NPDR, 0.77 (0.76, 0.77); and mild NPDR, 0.78 (0.77, 0.79). Lesion quantification results showed that the total hemorrhage area, maximum hemorrhage area, total exudation area, and maximum exudation area increase with DR severity.

Conclusions

SmartEye has a high diagnostic accuracy in DR screening program using non-mydriatic fundus cameras. SmartEye quantitative analysis may be an innovative and promising method of DR diagnosis and grading.
Effectiveness and implementation of evriMED with short messages service (SMS) reminders and tailored feedback compared to standard care on adherence to treatment among tuberculosis patients in Kilimanjaro, Tanzania: proposal for a cluster Randomized Controlled Trial SMS reminders and tailored feedback through evriMED and adherence to TB treatment

Published: May 2019

Background:
Adherence to Tuberculosis (TB) treatment is challenging because of many factors. The World Health Organization (WHO) has recommended the use of digital adherence monitoring technologies in its End-TB-strategy. However, there is paucity on its evidence in improving adherence. EvriMED is a real time medication monitoring (RTMM) device which was found feasible and acceptable in few studies in Asia. However, in Tanzania, there may be challenges in implementing evriMED due to stigmatization, network and power access, accuracy and cost effectiveness which may have an implication for treatment outcomes. We propose a pragmatic cluster randomized trial, to investigate the effectiveness of evriMED with reminder cues and tailored feedback on adherence to TB treatment in Kilimanjaro, Tanzania.

Methods:
We will create clusters in Kilimanjaro based on level of health care facility. Clusters will be randomized in an intervention arm, where evriMED will be implemented or a control arm, where standard practice Directly Observed Treatment (DOT) will be followed. TB patients in intervention clusters will take their medication from the evriMED pillbox and receive tailored feedback. We will use the ‘Stages­of-change’­model, which assumes that a person has to go through the stages of pre-contemplation, contemplation, preparation, action and evaluation to change behaviour for tailored feedback on adherence reports from the device.

Discussion:
If the intervention shows a significant effect on adherence and the devices are accepted, accurate and sustainable, the intervention can be scaled up within the National Tuberculosis Programmes.

Covariation among Root Biomass, Shoot Biomass, and Tiller Number in Three Rice Populations
Authors: Barnaby Jinyoung Y. , Pinson Shannon R. M. , Chun Jaebuhm , Bui Liem T.
Published: May 2019

Breeding for improved rice (Oryza sativa L.) root systems could improve crop yield by increasing water and nutrient uptake while also protecting the environment by reducing excess nutrients in runoff and methane emissions. Collection and measurement of roots is laborious, preventing direct selection for root biomass (RB) in large breeding populations. Tiller and root development are physiologically connected in rice where the root system is composed predominantly of nodal roots. Each tiller and its associated roots emerge from the same node on an originating stem. Here, we hypothesized that genes affecting tiller number (TN) also have sufficiently large effect on shoot biomass (SB) and RB that selections made on TN can be used to impart improvements in RB and SB. Associations among TN, RB, and SB were evaluated in three recombinant inbred line (RIL) rice mapping populations by first selecting subsets that were divergent for TN to determine if those contrasting RILs exhibited corresponding shifts in SB, RB, SB/RB, RB/TN, or SB/TN. Traits were measured in 6‐wk‐old potted plants. Selection for high vs. low TN resulted in corresponding shifts in RB and SB in all three populations, suggesting that it might be common for TN genes to also affect RB and SB through pleiotropy or linkage. However, further quantitative trait locus (QTL) study using 62 RILs of one population found instead that just one of the six detected TN‐QTL was co‐located with a RB‐QTL. Gene × gene interactions were detected, with TN selections causing larger shifts in RB and SB among a sd1 (semidwarf) subgroup than among the Sd1 sibling RILs in one of the populations.
Teaching Game and Simulation Based Probability
Authors: KOPARAN Timur
Published: May 2019

Technology and games are the areas where
learners are most interested in today's world. If these two can be brought
together within the framework of learning objectives, they can be an advantage
for teachers and students. This study aims to investigate the learning
environment supported by game and simulation. The games were used to evaluate
the basic probability knowledge of the prospective teachers, to demonstrate the
role of problem solving in the formation of the mathematical knowledge, and to
enable discussing mathematical ideas in a worksheet. Simulations were used for
visualization and a large number of experiments. The sampling of the study, by
which case study research is adopted, is comprised of 40 prospective teachers
at a state university in Turkey. The data were collected by introducing nine
open-ended questions by means of games, worksheets and simulation activities.
The questions asked relevant to the games include making predictions about the
fairness of the games, playing the games in small numbers and in big numbers
and the observation of the scores, calculation of the winning probabilities of
the gamers both experimentally and theoretically, and their comparisons. The
process of finding out the probability information underlying the games by the
prospective teachers was analyzed qualitatively by means of worksheets,
simulations and in-class observation, and the ways of thinking, intuitions,
estimations, strategies, and opinions about the learning situation of the
participants were tried to be determined. The results obtained put forward that
the learning situation that was set up simultaneously contributed to the
knowledge of probability and probability teaching of the prospective teachers;
and that the candidates’ opinions about the learning situation are positive.

Authors: Gabulov G. G. , Jabrailova G. I.
Published: May 2019

The authors studied the effect of selenium on the dynamics of immune system indicators in children with autoimmune thyroiditis. They examined 31 children (average age of 11.16 ± 0.59 years). Group I included 17 children who took selenium (100 μg per day for 6 months) along with the basic treatment. Group II (n=14) took L-thyroxin. The control group included 15 healthy children of the same age. The average level of selenium in children of Group I and II was 69.23 ± 1.52 μg / l at the beginning of the study, in the control group it was 114.8 ± 3.18 μg / l. Before treatment, children in Group I and II had T-cell suppression, the average level of all cytokines (especially TNF-α and IL-6) was significantly higher than in practically healthy children. The study demonstrated that the level of the thyroid tissue antibodies decreased significantly (p=0.001) with an increase in the level of selenium in the blood serum. By the end of the study the content of IgA (p=0.012) and IgG (p=0.044) in Group I, as well as the number of lymphocytes CD3 + (p=0.008), CD4 + (p=0.015), CD16 + / 56 + (p=0.010) significantly increased. The authors observed statistically significant decrease in the levels of TNF-α (p=0.028), IL-6 (p=0.002) and IL-1β (p=0.009) in children who took selenium in addition to the main treatment. Thus, the results of the study suggest that selenium in the complex therapy of autoimmune thyroiditis significantly reduces the titer of antithyroid antibodies and positively affects a number of important indicators of immune homeostasis in children.

Assessing the knowledge index of the region
Authors: Kukushkin S. N.
Published: May 2019

Economy of knowledge is an economic formation, where today’s generation of young people will work. It is quite good that many scientists try to forecast what it will be like. The article studies different approaches to assessment of regional knowledge index. The authors put forward a new methodology of its estimation on the basis of key matrix determinant and its logarithming. To assess the knowledge index 16 indicators divided into 4 groups are used and they gave an opportunity to build a four-dimensional matrix. According to the author, this approach is more objective and can eliminate some inaccuracy of methods designed by other authors. On the basis of this methodology the knowledge index was estimated, which shows conditions for shaping economy of knowledge in Russian regions. The rating of federal districts and regions-leaders was built and regions-outsiders in respect of economy of knowledge shaping were identified. Indicators that exert the most serious effect (positive and negative) on the knowledge index of regions were found. More detailed results for the whole period of analysis – 2000–2015 – for all regions of the Russian Federation can be found in the Situational Center of the Russian Plekhanov University of Economics.

As a practical discipline, crisis management began to actively develop in the 1990s. It was at this time that the objects and subjects of crisis management were determined, different approaches to definition were outlined, tasks, methods, and methods for solving them were formed. The article considers the existing approaches to the definition of crisis management, proposed by Russian and foreign scientists. The most interesting definitions of crisis management, which are used in the hotel business, are indicated. In the framework of the above definitions, examples are given on the implementation of crisis management in practice (in Russia and in foreign countries). Particular attention is paid to the classification of crises that affect the activities of hotel enterprises. Internal and external factors influencing the development of the hotel business are highlighted, and their ranking has been carried out. According to the results of the study, the shortcomings of the approaches to crisis management are presented, and a personal interpretation of the definition is proposed. World experience shows that crisis management was interested in scientists and practitioners from various fields: management, economics, finance, law, mathematical modeling, econometrics, programming, etc. Moreover, interest in crisis management arose most often at times when the world economy underwent a number of negative impacts. Currently, these phenomena have become quite frequent. Due to the fact that the markets and industries of the world have become interconnected, the financial market crisis leads to a decline in the development of the tourism industry, which in turn affects the hotel business.

Published: May 2019

Local, state and federal bodies of power use e-technologies (from automation to artificial intellect) in order to improve the life of the population. The new generation of computer complexes excel people in the intellect quality as a strategic tool of the economic development of the country and upgrading of its state governance. The article shows how to use technologies to raise efficiency at working places and to improve the life of the population. Principle opportunities of using e-technologies, big data and artificial intellect in state governance were studied. Prospects of processing the natural language by computers and building smart cities were described. In spite of enormous positive effect of introducing e-technologies, each new technology implies an additional risk. Such potential risks were estimated. Key trends of the future development of artificial intellect systems were analyzed, as they become a serious tool of process management. Today states face a new choice: should the managerial operations be completely automated, can the job be distributed between people and devices or should it be carried out by people with the help of devices. State sectors creating advantages of automation use such technologies as big data analysis, artificial intellect and Internet of things. Opportunities of artificial intellect are real and endless and things that were earlier only theoretical concepts, today form practical solutions.

The article proves inevitability of market management of national economy. The authors introduced in academic circulation such notions as ‘business market’ and ‘developed market.’ Serious attention is paid to the role of private property in life of society and organization of national economy. Drawbacks of national economy management in soviet times were shown, incompetence of party leaders was highlighted and this resulted in the fact that ways of coordinating industrial relations with economic laws were not found. The soviet power was not able to use market laws in the interests of the country. Party leaders were not eager to understand the market theory, as market was denied. Reforms were ineffective due to this reason. Today Russia is facing the necessity to choose strategy for the future: it could be an inertial way of neo-liberal reforms and degradation of scientific potential or mobilization of intellectual resources aiming at economy restructuring on the basis of developed market with the leading role of state. The quality of state governance can help renew social sphere, achieve sustainable growth in the standard of living, where the leading role will belong to science of life, man and society.
Property as a category of economic comparativistic
Authors: Skripnikova M. I. , Aleksandrova E. V. , Lisovskaya E. G.
Published: May 2019

The idea of the category ‘property’ is diverse and it is studied by economists, philosophers, lawyers, politologists and other experts. It is one of the basic categories in researching economic systems, especially economies being transformed as well as transitional ones. The subject is undoubtedly acute. Property is a category, which is filled by specific terms of different sciences, it is changeable in view of public expediency, economic and political situation and it becomes a key one in economic comparativistic. The goal of the article is to study and compare opinions of Russian and overseas scientists, academic schools and at the same time to investigate archive materials and academic works by present day academics dealing with the topic. The novelty of the article is connected with the multi-sided research of the category ‘property’. Theoretical and methodological foundation of the article was formed by principles of historism, system and comparative analysis, which support investigation of phenomena in their development and can be used with due regard to historical-retrospective and comparative-historical approach to such a phenomenon as property. On the basis of historical-genetic method it is possible to define the substantial content of the phenomenon. The authors also provide definitions of the notion ‘comparativistic’.

The Central Bank, the emission center, the reserve system, the federal treasury all these and other names are used to show the element of economy of a concrete state functioning, which controls money, i.e. estimates and administrates the money mass, buying capacity of residents in respect of goods, jobs and services, exerts influence on inflation processes and so on. The article provides results of researching the standing of normative and legal regulation, practice of using authority and responsibility, specific features of the Bank of Russia functioning as a relatively independent body of state governance and on this basis the articles studies the trends of improving management, norms of work development, procedures of working out and submitting to the State Duma of the Federal Assembly of the Russian Federation reports on federal laws bills, whose regulation is included in the competence of the Central Bank. Proposals dealing with amendments to the Federal law ‘About the Central Bank (the Bank of Russia)’ were formulated.
Biosynthesis and Characterization of Silver Nanoparticles Using Phoenix dactylifera Fruits Extract and their In Vitro Antimicrobial and Cytotoxic Effects
Authors: Zafar Sarvat , Zafar Aiman
Published: May 2019

Background:

In this article, silver nanoparticles (AgNPs) were synthesized by the biological green technique, using the aqueous extracts obtained from fruits of Phoenix dactylifera (date palm). This method is simple, rapid, non-toxic, and sustainable, and substitutes for the conventional physical/chemical methods. The cytotoxic activities of AgNPs derived from date fruit extract have not been mentioned in the earlier studies.

Methods:

The biosynthesized AgNPs are analyzed by Fourier transform infrared spectroscopy (FT-IR), UV-visible spectroscopy (UV-vis), and Transmission Electron Microscopy (TEM) methods. The assessment of antimicrobial effect towards human pathogenic microbial strains and their potential cytotoxicity against human breast cancer cell lines (MCF-7) were also evaluated.

Results:

FT-IR spectral studies showed that phytomolecules such as carbohydrates, phenolic acids and flavonoids present in date fruits extract are involved in the reduction and capping of the AgNPs. UV-vis spectrum revealed Surface Plasmon Resonance (SPR) at 425 nm which attributes the presence of AgNPs in aqueous extract. TEM micrographs showed that AgNPs particle diameter is ranged from 20 nm to 100 nm with spherical morphology. The biosynthesized AgNPs exhibited significant antimicrobial activity towards human microbial strains. Phytosynthesized NPs also induce cytotoxicity via necrosis, apoptosis and mitodepressive mechanisms that can disturb the cellular components at various stages of cell cycle.

Conclusion:

The present study concludes that biologically synthesized AgNPs using Phoenix dactylifera is cost-effective, rapid, non-toxic, and sustainable and can be effectively used as an adjunct for the treatment of breast carcinoma.

Published: May 2019

Background and Objectives:

Occupational exposure to silica dust can lead to biochemical damage. Malondialdehyde (MDA) can be considered as a primary marker for measuring the level of oxidative stress in a living organism. This study was conducted in order to evaluate the level of MDA in blood and urine of mice exposed to silica dust.

Material and Methods:

In this experimental study, 72 mice (BALB/c) were randomly allocated to five exposed groups and 1 control group. Exposure of mice to pure 99% silica dust was done in closed containers. Blood sampling was performed from the heart of mice and urine sampling fulfilled by insertion into a metabolic cage. The RAOet al. method was used to measure MDA.

Results:

The highest level of plasma MDA in group 1 in the 4thmonth was 8.4±0.41 nmol/l and the lowest level of MDA was 1.3±0.2 nmol/l in the third sampling in the control group, also the highest amount of urine MDA in the first and second groups and 4 months after exposure was 1.16±0.51 nmol/l, and the lowest in the control group and in the third sampling was 0.48±0.06 nmol/l. A significant difference was found between the levels of MDA in all exposed groups at different times except for the 5thgroup with the lowest concentration (P< 0.05).

Conclusion:

MDA in blood and urine could be proposed as a good biomarker for the evaluation of biochemical damages caused by silica dust. Measuring MDA is also a simple and inexpensive method that does not require complex equipment and can be used as an early detection test for biochemical damages caused by silica.
