Learning programming online: Influences of various types of feedback on programming performances
Authors: ÇAKIROGLU Ünal , ATABAS Samet , SARIYALÇINKAYA Dogukan , Öner Ibrahim Enes
Published: March 2020

This article draws on a one-semester online programming course to determine the relationships between the types of feedback that students received and their programming performances. An explorative study was designed including both quantitative and qualitative data. Participants were 15 second-year students enrolled at an Information Technology department of a public university who received weekly programming problems as projects. The instructor provided various types of feedback (corrective, confirmatory, explanatory, diagnostic and expanded feedback) to the students via Github. The results showed that; when the students who received corrective and explanatory feedback more, the programming performance scores were high. A strong positive relationship existed between a total amount of feedback with programming performance scores, also a number of times that students received explanatory feedback and programming performance scores. In addition, while the positive correlations existed between programming performance scores and the amount of all types of feedback, there was a weak correlation between the number of times that students received expanded feedback and programming performance scores. The difficulty of the programming projects, the needs of the participants and the affordances of the online learning environment played key role in the students’ preference for receiving feedback type. Recommendations for future research and practice are included.

Authors: Gong Tao , Tang Yongbai
Published: March 2020

Novel magnetic Fe3O4@SiO2-ethylenediamine tetraacetic acid (adsorbent) CMS–COOH-modified magnetic materials, CMS was prepared by surface modification of amino-functionalized Fe3O4@SiO2 (-NH2-modified magnetic materials, NMS) with EDTA using water-soluble carbodiimide as the cross-linker in deionized water solution. The phase structure, infrared spectra, thermal analysis and magnetic properties of were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetric analysis, and vibrating sample magnetometry and its properties for removal of heavy metal ions under varied experimental conditions were also investigated. The results revealed that CMS had good tolerance to low pH and exhibited good removal efficiency for the metal ions. The maximum adsorption capacities of CMS were found to be 0.11 mmol g−1 for Cu(II) at pH5.0 (30 °C) and 0.14 mmol g−1 for Pb(II) ions at pH2.0 (30 °C).
Spatial clustering of single-industry towns and a dynamic model of economic growth
Authors: Antonova Irina S. , Pchelintsev Evgeny A. , Popova Svetlana N.
Published: March 2020

This article studies the problems of economic growth and spatial development of regions with a high concentration of single-industry towns. The authors aim to identify the factors of development of single-industry towns at the microeconomic level on the basis of clustering and dynamic modeling of single-industry towns in three regions with the highest concentration — Kemerovo, Sverdlovsk, and Chelyabinsk Regions. This paper performs the clustering of single-industry towns by entropy indicators and the number of newly created enterprises, which allows distinguishing three “central” single-industry towns in each of the respective regions: Novokuznetsk, Nizhniy Tagil, and Magnitogorsk.
The clustering of single-industry towns with the use of the population-normalized index of the number of newly created enterprises allows us to refer these cities to two different clusters: Novokuznetsk against Nizhniy Tagil and Magnitogorsk with different parameters dominating. The correlation analysis of aggregate revenue, fixed assets, the share of the single industry, the entropy of revenue, the number of newly created enterprises of three single-industry towns allows suggesting a dynamic regression model. The peculiarity of this model is the inclusion as a variable of the number of the newly created enterprises in Nizhniy Tagil for all the cities under consideration, as well as the inclusion of a dummy variable reflecting the year of introduction of the program for the development of single-industry towns. Using the bootstrap method for Novokuznetsk, the authors have confirmed the significance of the introduction of this variable.
The results of the study have revealed both common patterns of regional development — the positive effect of reducing the share of monaurally and monocentric provision of single-industry towns in the regions for economic growth — and their differences — a contradictory effect of diversity in the central towns, as well as the assignment of Novokuznetsk and Nizhniy Tagil with Magnitogorsk from different clusters. In conclusion, the authors justify the early completion of the program of diversification of single-industry towns, designed to be ineffective in 2019.
Tool of forecasting the natural and migration movement of the population in the region based on simulation methods
Authors: Nizamutdinov Marsel M. , Atnabaeva Аlsu R.
Published: March 2020

The demographic policy of the Russian Federation is aimed at increasing the population in the country. In this connection, management decisions made at the regional level focus at attracting skilled migrants, increasing the birth rate, and reducing mortality. On the one hand, such politics affects the size of the population; on the other hand, the reaction of the population can adjust the policy. In turn, state programs are intended for a long period of time, thus, there is a need to assess the effectiveness of the taken decisions. Therefore, the authors have proposed a concept of an agent-based model of demographic processes at the regional level. In addition, they have developed the model itself, which aims to increase the accuracy of forecasting the population in the face of changing socio-economic indicators. Each of the agents (represented by “Person” and “Region”) have their own set of characteristics. To describe the logic of the agent behavior, the authors have used statistical (regression and cluster analysis) and probability (Bernoulli, Gamma, Betta, exponential distribution) methods. The life cycle of the agent “Person” is presented in the developed state diagram. The testing of the agent-based model was performed in solving the problems of forecasting the population in the Republic of Bashkortostan on the basis of the prognosis data from the RF Ministry of Economic Development.
The article also presents experimental research on two scenarios of economic development (basic and conservative). An assessment of changes in fertility, mortality, and migration based on the use of cluster and regression analysis is presented.
Interdisciplinary context of human capital study. Research program
Authors: Davydenko Vladimir A. , Andrianova Elena V. , Romashkina Gulnara F. , Khuziakhmetov Roman R.
Published: March 2020

The contemporary academic literature starts to recognize the importance of an individual in an organization, region, and national economy performance. Scholars try to explore the essence of interconnection between various forms of capital, institutional environment, and values. Hence, this article’s relevance is determined by the need to study the mechanisms of human capital and socio-economic achievements interrelation.
Human capital originates from knowledge, skills, abilities, and others characteristics of a person. It is not limited by a single individual, since, on the unit level, it becomes a resource through association and complementarity. The obtained combinations of human capital are complex, and almost all of them are specific to a particular organization. Therefore, the authors argue that competitive advantage is achieved mainly through a unique combination of human capital resources.
This article presents the key conceptual provisions of the polyparadigm research program of human capital phenomenon. The novelty of the article is determined, firstly, by a detailed description of human capital components, and secondly, by a proposal to implement the idea of interdisciplinary research. The authors have developed and tested a methodology that will allow for a comprehensive modular measurement of human capital, as well as for modeling and evaluating its impact on economic performance of micro-, meso-, and macro-entities in the context of economy digitalization.
The analysis base includes philosophical approaches, system analysis, social theories, sociology (including mathematical sociology), psychology, and economics. Systematization and typologization of scientific sources makes it possible to form a wide range of models of multilevel human capital and its resources. Moreover, the authors propose to initiate an interdisciplinary discussion, aimed at increasing the openness and productivity of research in this field.
The formation of civil identity among students based on formation of professional competencies and public activity: the experience of a multidimensional analysis
Authors: Tarasov Vladimir T. , Boyko Ivan I.
Published: March 2020

This article proposes methodological tools for analyzing the relationships between elements of complex social categories. It implements an approach based on the methods of multivariate statistical analysis, including factorial, canonical, and regression types. The proposed methods were experimentally tested on the data of a sociological survey of 688 students of metropolitan universities of Chuvashia in order to identify hidden relationships between the elements of synthetic categories that characterize civic identity, professional competencies, and the social activity of students. Regression dependencies and canonical correlations between the elements of these categories have confirmed the scientific hypothesis of the study that the formation of professional competencies in students during their studies increases their social activity and contributes to their civic identity. At the same time, hidden relationships between the elements of these categories have been identified, many of which turned out to be statistically significant. This hypothesis has not been previously investigated using this toolkit. The proposed methodological tools significantly expand the possibilities of sociological research.
The “smart city” concept and human capital
Authors: Kostko Natalya A. , Dolgikh Anastasia I.
Published: March 2020

The concept of a “smart city” uses the notion of a “smart citizen”, which is impossible to understand without the concept of human capital. The implementation of the “smart city” concept directly relates to the actualization of human capital. It is important to define the elements of human capital that characterize and ensure the success of embedding a person in the processes of digitalization in the modern social context.
This article provides an overview of modern approaches to the definition of the main elements of human capital. The authors aim to analyze foreign concepts for determining the elements of human capital that directly or indirectly affect the digitalization of society, the possibility of embedding each person in new conditions.
The presence of general global changes, however, varies by countries. An additional value of this research lies in enriching the definition of human capital from the perspective of an integrated approach to the definition of this concept. This approach involves considering human capital as a value, quality, resource, skills, competencies, and personality traits.
The authors conclude that human capital can be accepted as a system of aggregated indicators of social, psychological, organizational, and other capitals. In addition, the expanded interpretation of human capital with an emphasis on its embeddedness in the social context of society allows identifying the conditions that contribute to the formation of a smart citizen as the main actor in the implementation of the ‘smart city” concept. The social component of the “smart city” model in the person of a smart citizen can be implemented through their social activity, participation in the management of the implementation of the goals of digitalization of society.
Cellulose Nanofibrils-based Hydrogels for Biomedical Applications: Progresses and Challenges
Authors: Liu Huayu , Liu Kun , Han Xiao , Xie Hongxiang , Si Chuanling , Liu Wei , Bae Youngsoo
Published: March 2020

Background:

Cellulose Nanofibrils (CNFs) are natural nanomaterials with nanometer dimensions. Compared with ordinary cellulose, CNFs own good mechanical properties, large specific surface areas, high Young's modulus, strong hydrophilicity and other distinguishing characteristics, which make them widely used in many fields. This review aims to introduce the preparation of CNFs-based hydrogels and their recent biomedical application advances.

Methods:

By searching the recent literatures, we have summarized the preparation methods of CNFs, including mechanical methods and chemical mechanical methods, and also introduced the fabrication methods of CNFs-based hydrogels, including CNFs cross-linked with metal ion and with polymers. In addition, we have summarized the biomedical applications of CNFs-based hydrogels, including scaffold materials and wound dressings.

Results:

CNFs-based hydrogels are new types of materials that are non-toxic and display a certain mechanical strength. In the tissue scaffold application, they can provide a micro-environment for the damaged tissue to repair and regenerate it. In wound dressing applications, it can fit the wound surface and protect the wound from the external environment, thereby effectively promoting the healing of skin tissue.

Conclusion:

By summarizing the preparation and application of CNFs-based hydrogels, we have analyzed and forecasted their development trends. At present, the research of CNFs-based hydrogels is still in the laboratory stage. It needs further exploration to be applied in practice. The development of medical hydrogels with high mechanical properties and biocompatibility still poses significant challenges.
The Effect of CB1 Antagonism on Hepatic Oxidative/Nitrosative Stress and Inflammation in Nonalcoholic Fatty Liver Disease
Authors: Jorgačević Bojan , Vučević Danijela , Samardžić Janko , Mladenović Dušan , Vesković Milena , Vukićević Dušan , Ješić Rada , Radosavljević Tatjana
Published: March 2020

Dysfunction of the endocannabinoid system (ES) has been identified in nonalcoholic fatty
liver disease (NAFLD) and associated metabolic disorders. Cannabinoid receptor type 1 (CB1) expression
is largely dependent on nutritional status. Thus, individuals suffering from NAFLD and
metabolic syndrome (MS) have a significant increase in ES activity. Furthermore, oxidative/
nitrosative stress and inflammatory process modulation in the liver are highly influenced by the
ES. Numerous experimental studies indicate that oxidative and nitrosative stress in the liver is associated
with steatosis and portal inflammation during NAFLD. On the other hand, inflammation itself
may also contribute to reactive oxygen species (ROS) production due to Kupffer cell activation and
increased nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity. The pathways by
which endocannabinoids and their lipid-related mediators modulate oxidative stress and lipid peroxidation
represent a significant area of research that could yield novel pharmaceutical strategies for the
treatment of NAFLD. Cumulative evidence suggested that the ES, particularly CB1 receptors, may
also play a role in inflammation and disease progression toward steatohepatitis. Pharmacological
inactivation of CB1 receptors in NAFLD exerts multiple beneficial effects, particularly due to the
attenuation of hepatic oxidative/nitrosative stress parameters and significant reduction of proinflammatory
cytokine production. However, further investigations regarding precise mechanisms by
which CB1 blockade influences the reduction of hepatic oxidative/nitrosative stress and inflammation
are required before moving toward the clinical phase of the investigation.

Authors: Lv Bing , Jiang Xiao-Ming , Wang Da-Wei , Chen Jing , Han Dong-Feng , Liu Xiao-Liang
Published: March 2020

Background:

Cerebral ischemia-reperfusion injury is an extremely complicated pathological process
that is clinically characterized by high rates of disability and mortality. It is imperative to explore some effective
neuroprotective agents for its treatment. Ulinastatin is a protease inhibitor with anti-inflammatory and antioxidant
activity. For the past few years, new studies of ulinastatin for the treatment of ischemic brain injury have
emerged.

Objective:

We conducted a review to summarize the mechanisms of ulinastatin and analyze its neuroprotective
action against cerebral ischemia–reperfusion injury.

Methods:

We reviewed and summarized pertinent reports published between 1993 and 2019 from PubMed, Web
of Science, and Embaseby searching for the scientific terms ulinastatin, cerebral ischemia–reperfusion injury,
neuroprotective, stroke, cardiac arrest, and brain edema.

Results:

The protective mechanisms of ulinastatin in the key steps of cerebral ischemia–reperfusion injury include
inhibition of inflammatory response, oxidative stress, neuronal apoptosis, neuronal autophagy, and aquaporin-
4 expression as well as improvement in blood–brain barrier permeability. In addition, we provide a perspective
on potential research directions and clinical safety.

Conclusion:

Ulinastatin seems to have the potential to alleviate cerebral ischemia–reperfusion injury. These
findings may be valuable to further promote the research and development of drug candidates and provide novel
and reliable references for rational drug use.
Administration of Antioxidants in the Infertile Male: When it may have a Beneficial Effect?
Authors: Kopa Zsolt , Keszthelyi Marton , Sofikitis Nikolaos
Published: March 2020

Background:

Reactive Oxygen Species (ROS) are required for intact spermatogenesis and sperm
function, but excessive levels will cause oxidative stress, impairing sperms and sperm function due to membrane
damage and DNA fragmentation.

Objective:

Theoretically, antioxidant supplementation may act as a protection system against free radicals. Since
infertile males have higher levels of ROS, nutritional supplements are widely used for protecting sperms. In the
recent review, the authors summarize the most recent data regarding the effect of antioxidant treatment and draw
the attention of the limitations of antioxidant use in male infertility.

Methods:

The recent review gives an update of antioxidant treatment in male infertility.

Results:

Improvement of sperm parameters was reported in the majority of studies. Comparing different antioxidants
versus placebo showed low certainty of evidence with a serious risk of bias, and there is a lack regarding
certain doses, pregnancy rate, and live birth rate outcomes. Various clinical studies and randomized control trials
reported negative outcomes.

Conclusion:

An intact balance of oxidant and antioxidant systems is required for normal sperm function. No
guideline exists for the antioxidant dose regimen and treatment duration. Overdosing can result in reductive
stress, which is also harmful to fertility and can cause several diseases. Assessment of the pre-treatment redox
status can be recommended before the administration of exogenous antioxidants.
Clinical Application of Thiopurine Pharmacogenomics in Pediatrics
Authors: Pavlovic Sonja , Kotur Nikola , Stankovic Biljana , Gasic Vladimir , Lucafo Marianna , Decorti Giuliana , Zukic Branka
Published: March 2020

Background:

Thiopurine drugs are used for the treatment of pediatric diseases. Inter-individual differences
in the metabolism of these drugs greatly influence the risk of thiopurine induced toxicity and therapy failure.
These differences are the consequence of genomic, epigenomic and transcriptomic variability among patients. Pharmacogenomics
aims to individualize therapy according to the specific genetic signature of a patient. Treatment protocols
based on thiopurine drugs have already been improved by applying pharmacogenomics in pediatric clinical
practice.

Objective:

The aim of this review was to summarize the application of thiopurine pharmacogenomics in pediatric
patients suffering from acute leukemias, different types of autoimmune and inflammatory diseases, as well as in posttransplant
care.

Methods:

We searched PubMed/Medline database to identify thiopurine pharmacogenomic markers clinically relevant
in pediatric diseases.

Results:

TPMT and NUDT15 pharmacogenomic testing is done in pediatric care, contributing to the reduction of
thiopurine induced toxicity. Data on numerous novel potential pharmacogenomic markers relevant for optimization
of thiopurine treatment are still controversial (ITPA, ABCC4, NT5C2, PRPS1, GSTM1, FTO gene variants). Majority
of evidences regarding thiopurine pharmacogenomics in pediatrics have been acquired by studying acute lymphoblastic
leukemia and inflammatory bowel disease. For other pediatric diseases, namely acute myeloid leukemia,
non-Hodgkin lymphoma, juvenile idiopathic arthritis, atopic dermatitis, juvenile autoimmune hepatitis and renal
allograft transplantation, data are still scarce.

Conclusion:

Thiopurine pharmacogenomics has shown to be one of the best examples of successful application of
pharmacogenomics in pediatrics.
Chemical Metabolism of Xenobiotics by Gut Microbiota
Authors: Nakov Radislav , Velikova Tsvetelina
Published: March 2020

:

Among the gut microbiota’s newly explored roles in human biology is the ability to modify the chemical structures of foreign compounds (xenobiotics). A growing body of evidence has now provided sufficient acumen on the role of the gut microbiota on xenobiotic metabolism, which could have an intense impact on the therapy for various diseases in the future. Gut microbial xenobiotic metabolites have altered bioavailability, bioactivity and toxicity and can intervene with the actions of human xenobiotic-metabolizing enzymes to affect the destiny of other ingested molecules. These modifications are diverse and could lead to physiologically important consequences.

In the current manuscript we aim to review the data currently available on how the gut microbiota directly modifies drugs, dietary compounds, chemicals, pollutants, pesticides and herbal supplements.
Inhibitor Binding Sites in the Protein Tyrosine Phosphatase SHP-2
Authors: Zhang Haonan , Gao Zhengquan , Meng Chunxiao , Li Xiangqian , Shi Dayong
Published: March 2020

Protein tyrosine phosphatase 2 (SHP-2) has long been proposed as a cancer drug target.
Several small-molecule compounds with different mechanisms of SHP-2 inhibition have been reported,
but none are commercially available. Pool selectivity over protein tyrosine phosphatase 1 (SHP-1)
and a lack of cellular activity have hindered the development of selective SHP-2 inhibitors. In this review,
we describe the binding modes of existing inhibitors and SHP-2 binding sites, summarize the
characteristics of the sites involved in selectivity, and identify the suitable groups for interaction with
the binding sites.
Intracranial Atherosclerotic Stenosis is Related to Post-stroke Cognitive Impairment: A Cross-sectional Study of Minor Stroke
Authors: Gong Li , Wang Haichao , Dong Qiong , Zhu Xiaoping , Zheng Xiaoran , Gu Yongzhe , Cai Wangli , Zhao Yanxin , Liu Xueyuan
Published: March 2020

Background:

Intracranial Atherosclerotic Stenosis (ICAS) is an important risk factor for cognitive
impairment. However, it is unclear whether patients with ICAS are more likely to develop cognitive
impairment after an acute, non-disabling ischemic stroke (minor stroke).

Objective:

We aimed to investigate the association between ICAS and post-stroke cognitive impairment.

Methods:

In this cross-sectional study, patients with acute, non-disabling ischemic stroke underwent two
cognitive tests and imaging evaluation for ICAS, within two weeks after the stroke. To determine the
association between ICAS and post-stroke cognitive impairment, we performed a multivariate logistic
regression analysis adjusted for several demographic and vascular risk factors.

Results:

Of the 164 patients with minor stroke in this study, 98 (59.76%) were diagnosed with poststroke
cognitive impairment (Montreal Cognitive Assessment score<26). After adjusting for potential
confounders, we found that patients with ICAS were more likely to develop cognitive impairment after
an acute, non-disabling ischemic stroke, compared to patients without ICAS (Odds Ratio: 2.13; 95%
Confidence Interval: 1.07-4.26), and underperformed in the tests of visuospatial and executive function.

Conclusion:

In this cross-sectional study of a population that has experienced a minor stroke, our findings
demonstrated a positive association between ICAS and post-stroke cognitive impairment.
Synergism between Host Defence Peptides and Antibiotics Against Bacterial Infections
Authors: Li Jiarui , Fernández-Millán Pablo , Boix Ester
Published: March 2020

Background:

Antimicrobial resistance (AMR) to conventional antibiotics is becoming one of the main global health threats and novel alternative strategies are urging. Antimicrobial peptides (AMPs), once forgotten, are coming back into the scene as promising tools to overcome bacterial resistance. Recent findings have attracted attention to the potentiality of AMPs to work as antibiotic adjuvants.

Methods:

In this review, we have tried to collect the currently available information on the mechanism of action of AMPs in synergy with other antimicrobial agents. In particular, we have focused on the mechanisms of action that mediate the inhibition of the emergence of bacterial resistance by AMPs.

Results and Conclusion:

We find in the literature many examples where AMPs can significantly reduce the antibiotic effective concentration. Mainly, the peptides work at the bacterial cell wall and thereby facilitate the drug access to its intracellular target. Complementarily, AMPs can also contribute to permeate the exopolysaccharide layer of biofilm communities, or even prevent bacterial adhesion and biofilm growth. Secondly, we find other peptides that can directly block the emergence of bacterial resistance mechanisms or interfere with the community quorum-sensing systems. Interestingly, the effective peptide concentrations for adjuvant activity and inhibition of bacterial resistance are much lower than the required for direct antimicrobial action. Finally, many AMPs expressed by innate immune cells are endowed with immunomodulatory properties and can participate in the host response against infection. Recent studies in animal models confirm that AMPs work as adjuvants at non-toxic concentrations and can be safely administrated for novel combined chemotherapies.
Comparing Computed Tomography–Derived Augmented Reality Holograms to a Standard Picture Archiving and Communication Systems Viewer for Presurgical Planning: Feasibility Study (Preprint)
Authors: Dallas-Orr David , Penev Yordan , Schultz Robert , Courtier Jesse
Published: March 2020

BACKGROUND

Picture archiving and communication systems (PACS) are ubiquitously used to store, share, and view radiological information for preoperative planning across surgical specialties. Although traditional PACS software has proven reliable in terms of display accuracy and ease of use, it remains limited by its inherent representation of medical imaging in 2 dimensions. Augmented reality (AR) systems present an exciting opportunity to complement traditional PACS capabilities.

OBJECTIVE

This study aims to evaluate the technical feasibility of using a novel AR platform, with holograms derived from computed tomography (CT) imaging, as a supplement to traditional PACS for presurgical planning in complex surgical procedures.

METHODS

Independent readers measured objects of predetermined, anthropomorphically correlated sizes using the circumference and angle tools of standard-of-care PACS software and a newly developed augmented reality presurgical planning system (ARPPS).

RESULTS

Measurements taken with the standard PACS and the ARPPS showed no statistically significant differences. Bland-Altman analysis showed a mean difference of 0.08% (95% CI –4.20% to 4.36%) for measurements taken with PACS versus ARPPS’ circumference tools and –1.84% (95% CI –6.17% to 2.14%) for measurements with the systems’ angle tools. Lin’s concordance correlation coefficients were 1.00 and 0.98 for the circumference and angle measurements, respectively, indicating almost perfect strength of agreement between ARPPS and PACS. Intraclass correlation showed no statistically significant difference between the readers for either measurement tool on each system.

CONCLUSIONS

ARPPS can be an effective, accurate, and precise means of 3D visualization and measurement of CT-derived holograms in the presurgical care timeline.
System Architecture for "Support Through Mobile Messaging and Digital Health Technology for Diabetes" (SuMMiT-D): Design and Performance in Pilot and Randomized Controlled Feasibility Studies (Preprint)
Authors: Chi Yuan , Velardo Carmelo , Allen Julie , Robinson Stephanie , Riga Evgenia , Judge David , Tarassenko Lionel , Farmer Andrew J
Published: March 2020

BACKGROUND

Diabetes is a highly prevalent long-term condition with high morbidity and mortality rates. People with diabetes commonly worry about their diabetes medicines and do not always take them regularly as prescribed. This can lead to poor diabetes control. The Support Through Mobile Messaging and Digital Health Technology for Diabetes (SuMMiT-D) study aims to deliver brief messages as tailored interventions to support people with type 2 diabetes in better use of their diabetes medicines and to improve treatment adherence and health outcomes.

OBJECTIVE

This paper describes the overall architecture of a tailored intervention delivery system used in the pilot and randomized controlled feasibility studies of SuMMiT-D and reports its performance.

METHODS

The SuMMiT-D system includes several platforms and resources to recruit participants and deliver messages as tailored interventions. Its core component is called the clinical system and is responsible for interacting with the participants by receiving and sending SMS text messages from and to them. The personalization and tailoring of brief messages for each participant is based on a list of built-in commands that they can use.

RESULTS

For the pilot study, a total of 48 participants were recruited; they had a median age of 64 years (first quartile, third quartile [Q1, Q3: 54.5, 69]). For the feasibility study, a total of 209 participants were recruited and randomly assigned to either the control or intervention group; they had a median age of 65 years (Q1, Q3: 56, 71), with 41.1% (86/209) being female. The participants used the SuMMiT-D system for up to 6 months (26 weeks) and had a wide range of different interactions with the SuMMiT-D system while tailored interventions were being delivered. For both studies, we had low withdrawal rates: only 4.2% and 5.3% for the pilot and feasibility studies, respectively.

CONCLUSIONS

A system was developed to successfully deliver brief messages as tailored health interventions to more than 250 people with type 2 diabetes via SMS text messages. On the basis of the low withdrawal rates and positive feedback received, it can be inferred that the SuMMiT-D system is robust, user-friendly, useful, and positive for most participants. From the two studies, we found that online recruitment was more efficient than recruitment via postal mail; a regular SMS text reminder (eg, every 4 weeks) can potentially increase the participants’ interactions with the system.

Published: March 2020

Ecological studies on the vector species diversity usually focused on particular habitats and not a comparative study. Therefore, a research has been carried out to see the variation from one of many aspects which affects the condition of a habitat such as altitude. This study aimed to determine the Anopheles spp. species diversity between highland and lowland captured in the research of Vektora 2015-2016 in East Nusa Tenggara Province, Indonesia. This study is a further analysis of Vektora Research Data from 2015 to 2016 in East Nusa Tenggara Province. The population in this study is the whole Anopheles spp. in East Nusa Tenggara Province from 2015-2016. The sample is Anopheles species caught on Vektora. The variables used in this study are categorical variables of highland or lowland, Anopheles species and dominance index. This study results indicate that there is a significant difference in the number of Anopheles obtained per species between the lowlands and the highlands.

Set theory has a wide role in mathematical concepts. Students have to understand the set theory before learning other concepts such as algebra and probability. This study aims to determine the effect of the problem-based learning (PBL) model on the students’ mathematical representation in set theory topics. The method used in this study is a quasi-experiment design. The populations in this study were 289 students of 7th grade at Secondary School in Palembang. The sample of this study were students of class 7.8 (control group) and 7.10 (experimental group). Data were collected through tests, interviews, and documentation. Based on data analysis, known that PBL affects the students’ mathematical representation. Students who had the PBL model get the better score of mathematical representation. They could use the symbol of set correctly, represent the set into Venn diagram correctly and they also could explain their answer. Furthermore, the implementation of the PBL model is offered.

This article contains students' answers to the row and series questions which are then analyzed based on the Watson category. The problem that often arises is a large number of students who still cannot give the right answer to the sequence and sequence problems. Analysis very important to do, especially on the wrong answers so that the teacher knows where the student lies in solving a problem so the teacher can take appropriate corrective action. The Watson category is used to facilitate the tracking of errors that are often made by students. This paper describes the types of errors in solving row and series problems based on the Watson category and describes the percentage of each type of error. This type of research is a descriptive study with a qualitative approach. This research was conducted by giving a test about sequences and series question in the form of a description of four questions. The results showed that there were two categories based on Watson which were dominantly carried out by students, namely 1) incorrect procedures (34.06%) and 2) conclusions were lost (20.33%).

These Students' mathematical problem solving behavior had been presented in the previous paper. Four categories of students' mathematical problem solving behavior in junior high schools in Indonesia had been obtained. These categories were: naive, routine, semi-sophisticated, and sophisticated. This paper was a continuation of that research. In this session would discuss about external aspects affect student behavior in problem solving. This research used survey method. Eighteen students from three junior high schools in Indonesia had been interviewed about it. These three aspects were: distance of home from school, family background, Contests-contests like math Olympiads that had been followed. The interview results were coded to get conclusions. Research findings were that the external aspects of students did not influence students in behaving to solve problems in mathematics. the implication of this finding is that the main factor influencing student behavior in problem solving is teacher professionalism in learning not from the students themselves, so the teacher must be really prepared in designing all components of learning well.

A indústria da construção civil é a que mais gera resíduos sólidos, contribuindo com o agravamento da agressão ambientalatravésdosseusdescartesinapropriados. Estetrabalhoapresentaumestudosobreareciclagemde agregados graúdos de resíduos da construção civil e demolição (RCD) do tipo classe A, para serem utilizados na fabricação de concretos convencionais para fins específicos ou mesmo na sua utilização em sub-base de rodovias. Devido à inexistência de uma usina de reciclagem de RCD na Bahia e Sergipe, os Agregados Graúdos Reciclados (AGR) utilizados nesta pesquisa foram oriundos de Guarulhos - São Paulo, obtidos conforme a NBR 15116/14. Os agregados foram submetidos inicialmente a um tratamento mecânico de catação, para eliminar contaminantes e peneiramento, para diminuir os finos. Em seguida foram feitas caracterizações físicas através dos ensaios de granulometria, massa unitária no estado solto, massa específica e material pulverulento.Os ensaios físicos indicaram que os agregados reciclados podem ser usados para a fabricação de concretos convencionais simples para serem aplicados em pavimentação, construção de passeios e ruas, casas populares e contensão de encostas, escolas municipais e meio fios, drenagem de águas pluviais, etc. Dessa forma, com o aprofundamento das pesquisas e adequação da NBR 6118, poderá ser viabilizada a utilização do AGR na produção de concretos reciclados convencionais para fins específicos e gerais, e consequentemente, ampliar o volume reciclado de resíduos da construção civil e demolição, minimizando os impactos negativos ambientais, gerando emprego e renda e melhorando as condições sócias e econômicas das comunidades do Recôncavo da Bahia.

Study of droplet dynamics and condensation heat transfer on superhydrophobic copper surface
Authors: Yuvaraj R. , Senthkil Kumar
Published: March 2020

Superhydrophobic surface for dropwise condensation is prepared using hotplate solution immersion method on copper substrate. The preprocessed bare copper plate is immersed in a solution consist of 0.004-0.008 M ethanol (CH3-CH2-OH) and tetradecanoic acid (CH3(CH2)12COOH) then heating the plates in the solution at 30-50?C for 1-6 hours. The contact angle of water droplet on the prepared surface is measured using low bond axisymmetric drop shape analysis, which gives the maximum contact angle of 168? and average value of 166? ?2?. The maximum contact angle is obtained by adjusting the composition of the solution, temperature of the solution and immersion time to 0.006 M, 45?C and 4 hours, respectively. The various superhydrophobic surfaces are prepared by changing constituents of solution, hotplate temperature and processing time, respectively. Further dynamic behavior of water droplet on the prepared surfaces like jumping effect and rolling effect is presented in this work. In addition, experimental work is carried out on the prepared surface for dropwise condensation and the obtained results are com-pared with condensation on bare copper plate produces higher heat transfer coefficient.
