Authors: Choi Young In , Choi Eun-sook , Mun Kwan Ho , Lee Se Guen , Lee Sung Jun , Jeong Sang Won , Lee Seung Woo , Kim Hyun-Chul
Published: April 2019

Polymeric micelles as drug delivery vehicles are popular owing to several advantages. In this study, a gemini amphiphile (gemini mPEG-Cys-PMT) consisting of hydrophilic poly(ethylene glycol) and hydrophobic poly(methionine) with cystine disulfide spacer was synthesized and its micellar properties for thiol- or reactive oxygen species (ROS)-dependent intracellular drug delivery were described. The cleavage of cystine linkage in a redox environment or the oxidation of methionine units in a ROS environment caused the destabilization of micelles. Such redox- or ROS-triggered micellar destabilization led to enhanced release of encapsulated doxorubicin (DOX) to induce cytotoxicity against cancer cells. Further, the therapeutic effects of the DOX-loaded micelles were demonstrated using the KB cell line. This study shows that thiol and ROS dual-responsive gemini micelles are promising platforms for nano-drug delivery in various cancer therapies.
Thermoresponsive Poly(N-Isopropylacrylamide-co-Dimethylaminoethyl Methacrylate) Microgel Aqueous Dispersions with Potential Antimicrobial Properties
Authors: Echeverría Coro , Aragón-Gutiérrez Alejandro , Fernández-García Marta , Muñoz-Bonilla Alexandra , López Daniel
Published: April 2019

The work herein describes the preparation of thermoresponsive microgels with potential antimicrobial properties. Most of the work performed so far regarding microgels with antimicrobial activity, deals with the ability of microgels to carry and release antibiotics or antimicrobial agents (antimicrobial peptides). The originality of this work lies in the possibility of developing intrinsic antimicrobial microgels by copolymerization of the well-known thermoresponsive monomer, N-isopropylacrylamide (NIPAM) with dimethylaminoethyl methacrylate (DMAEMA), a water-soluble monomer, to form microgels via precipitation polymerization (radical polymerization). Due to the presence of a tertiary amine in the DMAEMA comonomer, microgels can be modified by N-alkylation reaction with methyl and butyl iodide. This quaternization confers positive charges to the microgel surfaces and thus the potential antimicrobial activity. The effect of DMAEMA content and its quaternization with both, methyl and butyl iodide is evaluated in terms of thermal and surface charge properties, as well as in the microgel size and viscoelastic behavior. Finally, a preliminary study of the antimicrobial activity against different microorganisms is also performed in terms of minimum inhibitory concentration (MIC). From this study we determined that in contrast with butylated microgels, methylated ones show potential antimicrobial activity and good physical properties besides of maintaining microgel thermo-responsiveness.
What Julian Saw: The Embodied Showings and the Items for Private Devotion
Authors: Dresvina Juliana
Published: April 2019

The article traces potential visual sources of Julian of Norwich’s (1343–after 1416) Revelations or Showings, suggesting that many of them come from familiar everyday devotional objects such as Psalters, Books of Hours, or rosary beads. It attempts to approach Julian’s text from the perspective of neuromedievalism, combining more familiar textual analysis with some recent findings in clinical psychology and neuroscience. By doing so, the essay emphasizes the embodied nature of Julian’s visions and devotions as opposed to the more apophatic approach expected from a mystic.
Volcanic Cloud Top Height Estimation Using the Plume Elevation Model Procedure Applied to Orthorectified Landsat 8 Data. Test Case: 26 October 2013 Mt. Etna Eruption
Authors: de Michele Marcello , Raucoules Daniel , Corradini Stefano , Merucci Luca , Salerno Giuseppe , Sellitto Pasquale , Carboni Elisa
Published: April 2019

In this study, we present a method for extracting the volcanic cloud top height (VCTH) as a plume elevation model (PEM) from orthorectified Landsat 8 data (Level 1). A similar methodology was previously applied to raw Landsat-8 data (Level 0). But level 0 data are not the standard product provided by the National Aeronautics and Space Administration (NASA)/United States Geological Survey (USGS). Level 0 data are available only on demand and consist on 14 data stripes multiplied by the number of multispectral bands. The standard product for Landsat 8 is the ortho image, available free of charge for end-users. Therefore, there is the need to adapt our previous methodology to Level 1 Landsat data. The advantages of using the standard Landsat products instead of raw data mainly include the fast -ready to use- availability of the data and free access to registered users, which is of major importance during volcanic crises. In this study, we adapt the PEM methodology to the standard Landsat-8 products, with the aim of simplifying the procedure for routine monitoring, offering an opportunity to produce PEM maps. In this study, we present the method. Our approach is applied to the 26 October 2013 Mt. Etna episodes comparing results independent VCTH measures from the spinning enhanced visible and infrared imager (SEVIRI) and the moderate resolution imaging spectroradiometer (MODIS).
Influence of the System MTF on the On-Board Lossless Compression of Hyperspectral Raw Data
Authors: Aiazzi Bruno , Selva Massimo , Arienzo Alberto , Baronti Stefano
Published: April 2019

A noticeable topic to be pursued in the field of on-board real-time data processing is the influence of the modulation transfer function (MTF) of the image acquisition system on the lossless compressibility of raw (that is, uncalibrated) hyperspectral data. Actually, notwithstanding the system device is constrained by several design and manufacturing requirements, the impact of the on-board MTF on the performance of data compressors is becoming remarkable. In particular, the aim of reducing both transmission bandwidth/power and mass storage can be efficiently pursued. Such an analysis is expected to be useful especially for systems employed in mini-satellites, whose payload must be compact and light. From this perspective, this paper investigates the performance of a typical imaging system that acquires low/medium-spatial-resolution images, by considering high-resolution reference data, which simulate the real scene to be imaged. To this end, standard Consultative Committee for Space Data Systems (CCSDS) Aviris 2006 data have been chosen, due to their spatial resolution of 17 m, which is adequate to be a reference for simulated data whose spatial resolution is foreseen between 50 and 150 m. MTF requirements are usually provided based on the cut-off value of the amplitude at the Nyquist frequency, which is defined as a half of the sampling frequency. Typically, a cut-off value between 0.2 and 0.3 ensures that a sufficient amount of information is delivered from the scene to the acquired image, by avoiding at the same time the degradation due to an excessive aliasing distortion. All the scores are achieved by running the standard lossless compression scheme CCSDS 1.2.3.0-B-1 for multispectral/hyperspectral data, as a function of the cut-off value and different noise acquisition levels. The final results, and related plots, show that this analysis can suggest a suitable choice for the cut-off value, to ensure both a sufficient quality and low bit rates for the transmitted data to the ground station.
Gear Tooth Profile Reconstruction via Geometrically Compensated Laser Triangulation Measurements
Authors: Tian Hao , Wu Fan , Gong Yongjun
Published: April 2019

Precision modeling of the hydraulic gear pump pressure dynamics depends on the accurate prediction of volumetric displacement in the inter-tooth spaces of the gear. By accurate reconstruction of the gear profile, detailed transient volumetric information can be determined. Therefore, this paper reports a non-contact gear measurement device using two opposing laser triangulation sensors, and the key geometrical models to reconstruct the profile with geometrical error compensation. An optimization-based key parameter calculation method is also proposed to find the unknown orientation of the sensor. Finally, an experimental setup is established, the performance of the device is tested and the geometric model is validated. Initial results showed that the method is able to reconstruct the target tooth profile and compensated results can reduce the geometrical error by up to 98% compared to the uncalibrated ones.
Formation Generation for Multiple Unmanned Vehicles Using Multi-Agent Hybrid Social Cognitive Optimization Based on the Internet of Things
Authors: Yao Zheng , Wu Sentang , Wen Yongming
Published: April 2019

Multi-agent hybrid social cognitive optimization (MAHSCO) based on the Internet of Things (IoT) is suggested to solve the problem of the generation of formations of unmanned vehicles. Through the analysis of the unmanned vehicle formation problem, formation principles, formation scale, unmanned vehicle formation safety distance, and formation evaluation indicators are taken into consideration. The application of the IoT enables the optimization of distributed computing. To ensure the reliability of the formation algorithm, the convergence of MAHSCO has been proved. Finally, computer simulation and actual unmanned aerial vehicle (UAV) formation generation flight generating four typical formations are carried out. The result of the actual UAV formation generation flight is consistent with the simulation experiment, and the algorithm performs well. The MAHSCO algorithm based on the IoT is proved to be able to generate formations that meet the mission requirements quickly and accurately.
Measurement of Social Networks for Innovation within Community Disaster Resilience
Authors: Wilkin Joanna , Biggs Eloise , Tatem Andrew
Published: April 2019

Disaster risk reduction (DRR) research has long recognised that social networks are a vital source of support during and after a shock. However, the quantification of this social support, primarily through its recognition as social capital, has proven problematic as there is no singular method for its measurement, invalidating the credibility of studies that try to correlate its effects with community disaster resilience. Within the wider resilience field, research that specifically utilises social networks as the focus of analysis is evolving. This paper provides a critical synthesis of how this developing discourse is filtering into community disaster resilience, reviewing empirical case studies from the Global South within DRR that use social network analysis and connectivity measurement. Our analysis of these studies indicates that a robust methodology utilising social network analysis is emerging, which offers opportunity for research cross-comparability. Our review also finds that without this bottom-up mapping, the implementation of top-down preparedness policy and procedures are likely to fail, resulting in the advocation of social network analysis as a critical methodology in future resilience research and policy planning.
What Are the Features of Successful Medical Device Start-Ups? Evidence from KOREA
Authors: Lee Munjae , Park Sewon , Lee Kyu-Sung
Published: April 2019

This study analyzes the factors determining the success of medical device start-ups, focusing on the healthcare sector as the starting point of the Fourth Industrial Revolution. The government is also working to establish a business model to revitalize medical device start-ups as a new driving force for the economy. Accordingly, such start-ups based on innovative technologies have been actively developed, but it seems that there is a limit to growth. We employed an analytical hierarchy process to derive an activation strategy for medical device start-ups. A survey was administered to experts in such start-ups, including medical device companies and venture capital firms, prospective start-up entrepreneurs, medical device developers, and professors. A total of 18 responses were obtained for analysis. The results revealed the following priorities for the success of medical device start-ups: technical skills, marketability, entrepreneurial capacity, and funding. In addition, medical device and venture capital firms were divided into separate groups and compared and analyzed. Technical skills are considered a priority for those in the medical industry. However, entrepreneurial skills are a priority for venture capitalists. Based on these results, we suggest measures for the success of medical device start-ups.
Research on Tibetan Folk’s Contemporary Tibetan Cultural Adaptive Differences and Its Influencing Factors—Taking ShigatseCity, Tibet, China as an Example
Authors: Yongchun Yang , Yan Sun , Weiwei Wang
Published: April 2019

Using qualitative research methods and mathematical statistical analysis, taking Shigatse city in Tibet as a case study area, and based on the affective, behavioral, and cognitive (ABC) model and cultural distance theory, we explore the Tibetan people’s cultural adaptive types, differences, and its influencing factors. The results show that there are seven Tibetans’ cultural adaptive kinds: Integration, assimilation, isolation, marginalization, tending to Tibetan modern culture, adaptation to Tibetan traditional culture, and unclassified cultural adaptive style. The Tibetans’ cultural adaptive tendency mainly integrates between modern and traditional parts in the contemporary Tibetan local cultures. Meanwhile, the Tibetan folk still has a large proportion of modifying to traditional culture. Moreover, the Tibetans’ cultural adjusted differences in the affective and cognitive dimensions are smaller than the acculturate features in the behavioral side. However, the cultural adjusted distinctions in the affective and cognitive aspects compared to that in the behavioral field are more complex. Moreover, there are direct and mediating effects that impact the Tibetan folks’ cultural adaptability. Studying Tibetan people’s cultural adaptation may be conducive to understanding the evolution of Tibetan locality’s meaning and the mutual game between the two different parts in local culture as well as comprehending the Tibetan folks’ real cultural appeal. The conclusions have important practical significance of the harmony, stability, unity, progress, and information in China ethnic areas’ economy, society, and culture.
Economic Development and Female Labour Force Participation: The Case of European Union Countries
Authors: Altuzarra Amaia , Gálvez-Gálvez Catalina , González-Flores Ana
Published: April 2019

In this paper, we studied the relationship between female labour force participation and economic development in the 28 countries of the European Union during the period 1990–2016. The analysis was carried out from two different viewpoints: first, we studied all the countries of the EU-28, and second, the evidence was disaggregated into two groups of countries: old (EU-15) and new (EU-13) member estates. The data used came from the World Bank open data repository and Eurostat. The methodology used consisted of the estimation of static (Ordinary Least Squares (OLS) and Fixed Effects (FE)) and dynamic (generalized moments model—GMM) models. Results for all European countries (EU-28) were consistent with the hypothesis which suggests the existence of a U-shaped relationship between female labour force participation and economic development. When the sample was broken down into groups, we found evidence that confirms the feminization hypothesis for the new countries of the EU, but not for the old ones.
Sustainable Financing for Sustainable Development: Agent-Based Modeling of Alternative Financing Models for Clean Energy Investments
Authors: Ari Ibrahim , Koc Muammer
Published: April 2019

Renewable energy investments require a substantial amount of capital to provide affordable and accessible energy for everyone in the world, and finding the required capital is one of the greatest challenges faced by governments and private entities. In a macroeconomic perspective, national budget deficits and inadequate policy designs hinder public and private investments in renewable projects. These problems lead governments to borrow a considerable amount of money for sustainable development, although such excessive debt-based financing pushes them to unsustainable economic development. This substantial amount of borrowing makes a negative contribution to the high global debt concentration, putting countries’ economic and social development at risk. In line with this, excessive debt-based financing causes an increase in wealth inequality, and when wealth inequality reaches a dramatic level, wars and many other social problems are triggered to correct the course of wealth inequality. In this regard, the motivation behind the study is to develop a set of policy guidelines for sustainable financing models as a solution for these intertwined problems, which are: (1) a financial gap in energy investments; (2) an excessive global debt concentration; and (3) a dramatic increase in wealth inequality. To this end, this study presents a quantitative and comparative proof of concept analysis of alternative financing models in a solar farm investment simulation to investigate the change in wealth inequality and social welfare by reducing debt-based financing and increasing public participation. There are many studies in the literature investigating the evolution of wealth inequality throughout history. However, there is a gap in the literature, and investigating the effects of various policy rules on the evolution of wealth inequality in a future time frame needs to be explored in order to discuss possible policy implications beforehand. In this respect, this paper contributes to the literature by developing simulation models for conventional and alternative financing systems. This enables investigating the changes in wealth inequality and social welfare as a result of various policy implications throughout the simulation time.
Sectoral Regional Growth and Convergence in Ecuador: An Analysis of the Intra-Distributive Dynamics of Productivity
Authors: Quintana-Romero Luis , Correa-Quezada Ronny , Ramón-Mendieta Marlon G. , Álvarez-García José
Published: April 2019

The objective of this research is to examine growth and convergence processes in the provinces of Ecuador, considering sectoral productivity as an analysis variable. To do so, evidence of the productivity of the agricultural, secondary and service sectors is presented, and by applying the non-parametric method of density functions of the kernel, the complete distribution of the data is analyzed. The results obtained indicate that territorial inequality in Ecuador has very different behavior depending on the sectors of the economy. It is noted that inequality in terms of productivity is very high in the agricultural sector, it is at an average level in the secondary sector, and is less intense in the service sector. In the long-term, the overall balance is that sectoral inequality decreased among Ecuadorian provinces. However, there are two processes differentiated in time; in the first phase, inequality decreases more rapidly and in the second phase, it even increases in some sectors, as in the case of secondary sector returns.
Consistency Checking and Improving for Interval-Valued Hesitant Preference Relations
Authors: Zhai Yuling , Xu Zeshui
Published: April 2019

Group decision making (GDM), which aims to obtain a sensible decision result with several decision makers, is a common occurrence in daily life. Since the uncertainty of the objects is a thorny issue in the process of GDM, it is important to eliminate uncertainty in order to achieve an optimal decision result. Considerations of some types of preference relations based on various fuzzy sets have been presented and investigated in previous studies; in this paper, we define the interval-valued hesitant multiplicative preference relation (IVHMPR) and the multiplicative consistency of IVHMPR. Based on these, we provide a detailed discussion on the connections between the interval-valued hesitant fuzzy preference relation (IVHFPR) and the IVHMPR. Then, we give a method to check the for unacceptable consistency of IVHFPR and IVHMPR, and improve them to make the consistency acceptable. Finally, an illustrative example of selecting the optimal treatment for a lung cancer patient is given to demonstrate our work in detail.
Protein Structure-Guided Hidden Markov Models (HMMs) as A Powerful Method in the Detection of Ancestral Endogenous Viral Elements
Authors: Kirsip Heleri , Abroi Aare
Published: April 2019

It has been believed for a long time that the transfer and fixation of genetic material from RNA viruses to eukaryote genomes is very unlikely. However, during the last decade, there have been several cases in which “virus-to-host” gene transfer from various viral families into various eukaryotic phyla have been described. These transfers have been identified by sequence similarity, which may disappear very quickly, especially in the case of RNA viruses. However, compared to sequences, protein structure is known to be more conserved. Applying protein structure-guided protein domain-specific Hidden Markov Models, we detected homologues of the Virgaviridae capsid protein in Schizophora flies. Further data analysis supported “virus-to-host” transfer into Schizophora ancestors as a single transfer event. This transfer was not identifiable by BLAST or by other methods we applied. Our data show that structure-guided Hidden Markov Models should be used to detect ancestral virus-to-host transfers.

ABSTRACT

The present work is directed to analyze the experiences of Virtual Education in the learning of the students of the Faculty of Philosophy at the Technical University of Manabí. Virtual Education is born as a strategy that allows to dynamize and flexibilize the teaching processes, to incorporate strategies of cooperative learning, creating new conditions to learn, where the student is the architect of the knowledge. Implementing a balanced methodological model, I agree with Taylor (1999) and Martín (1998) that virtual education is affordable, whereas in earlier times it was difficult to study either for work and time, today it is not limited to studying and allows to build its own schedule According to their  needs,  since  this  is  a  model  of  flexible  education,  and  requires  the student's responsibility in each of the tasks entrusted. However one of the great difficulties, which have been shown, is that not all students have Internet, another is the economic factor that makes it impossible to access the Internet.

El Observatorio Sismológico de la Universidad del Quindío (OSQ) cuenta con 6 estaciones sismológicas (Bolívar y Peñas Blancas de banda ancha, Caicedonia y Peñas Blancas analógicas, Modín y Riberalta de tipo digital) y 3 estaciones acelerográficas (Uniquindio, Calarcá y Génova) distribuidas estratégicamente en el departamento del Quindío y el Valle del Cauca con los que se lleva a cabo el monitoreo de la actividad sísmica de la zona. Dichas estaciones se encuentran georreferenciadas, pero son datos tomados hace 20 años que no han sido referenciados usando equipos de alta precisión, por esta razón, el Sistema de Posicionamiento (GNSS) se implementa con ayuda de un software especializado en la compilación de los datos y por consiguiente se mejora la localización de los eventos sísmicos registrados en el (OSQ). Para la recolección de la información se programaron campañas de medición usando la herramienta de Software GNSS Planning Online que permite conocer el día y el horario en que existe mayor disponibilidad de satélites para obtener mayor precisión. Para el procesamiento de los datos, se utilizó el método de postproceso que permite corregir los errores sistemáticos que se presentan durante la captura de información en campo y posteriormente se realizó un ajuste con el software TopCon Tools para entregar resultados con el menor error posible. Como producto final de la investigación, se entrega al (OSQ), un catálogo con las coordenadas geográficas de las estaciones debidamente georreferenciadas y ubicadas en un mapa de la región dejando un insumo que favorece las actividades realizadas por esta dependencia.

Background

Little is known about clinicians’ experiences of using a point-of-care test (POCT) to inform management of urinary tract infection (UTI) in general practice.

Aim

To explore experiences of using the Flexicult test to inform management of UTI and views on requirements for an optimal POCT to inform successful implementation.

Design & setting

Telephone interviews with 35 primary care clinicians and healthcare professionals in Wales, England, Spain, and the Netherlands, who had participated in a trial of the Flexicult POCT for UTI based on urine culture.

Method

Thematic analysis of semi-structured interviews.

Results

Most primary care clinicians interviewed agreed on the need for a POCT in UTI management, and that the Flexicult POCT delivered quicker results than laboratory results used in usual care, reassured patients, boosted their confidence in decision-making, and reminded them about antibiotic stewardship. However, clinicians also reported difficulties in interpreting results, limitations on when the Flexicult could be used, and concerns that testing all patients would strain care delivery and prolong patient discomfort when delaying decisions until a non-rapid POCT result was available. An optimal POCT would produce more rapid results, and be reliable and easy to use. Uptake into routine care would be enhanced by: clear guidance on which patients should be tested; training for interpreting ‘grey area’ results; reiterating that even ‘straightforward’ cases might be better managed with a test; clear messages about stopping unnecessary antibiotics versus completing a course; and better self-management strategies to accompany implementation of delayed, or non-prescription of, antibiotics.

Conclusion

Primary care clinicians believe that POCT tests could play a useful role in the management of UTI and gave clear recommendations for successful implementation.

The article describes the technology of designing asphalt pavements, according to the Superpave method. The Superpave System (SUperior PERforming Asphalt PAVEments) is developed by the US Strategic Highway Research Program (SHRP). The goal of the program is to search for new ways of designing asphalt concrete pavements that will work better under extreme temperatures and intensive traffic loads. The Superpave system is primarily concerned with two problems associated with road surface: constant deformation, which is a consequence of insufficient strength of asphalt concrete in shear at high temperatures; and low-temperature damage, which is formed during the compression of the asphalt concrete pavement, the tensile stress exceeds the tensile strength. The solution of these problems is carried out by the most rational selection of components of the asphalt concrete mix. This technology has interested Russia relatively recently. In 2016, preliminary national standards have been translated and issued. They describe requirements of materials for design and selection of the mixture. The article reviews technical documentation in order to develop a methodology for the selec-tion of asphalt mix. In the course of the research, the technological features of selection and design of the asphalt mix using the given method are considered and a block diagram is made for the selection of asphalt composition. This system makes it possible to design the fine-grained and gravel-mastic as-phalt mixes. The introduction of foreign experience in the construction of roads can contribute to the quality improvement of Russian highways

Interior paint is important for interior decorating; this is followed by a long time working with the col-oring material and a constant stay in rooms with the paint. Unfortunately, not all paints provide com-fortable and safe use. This article presents the development of eco-friendly water-dispersion paint based on polyvinyl acetate dispersion. This paint provides protection from carcinogenic, mutagenic and toxic effects. The main environmental requirements set by the standards are considered; the con-tent of substances in the paint that harms people is monitored. The influence of some paint compo-nents on person’s functionality and the possibility of their replacing without quality reduction is dis-closed in the paper. The main physical and mechanical properties such as conditional viscosity, densi-ty, mass fraction of nonvolatile substances, coating adhesion, milling degree, resistance to static ac-tion of water and weather resistance are determined. Attention is paid to the applied research meth-ods. As a result of testing, a water-dispersion paint with high technical characteristics is obtained. It can be used in all types of buildings and structures and be recommended for children's, medical and preventive institutions.
