Authors: Wei Guanyun , Sun Lianjie , Qin Shijie , Li Ruimin , Chen Liming , Jin Ping , Ma Fei
Published: September 2018

Abnormal expressions of microRNA (miRNA) can result in human diseases such as cancer and neurodegenerative diseases. MiRNA mainly exert their biological functions via repressing the expression of their target genes. Drosophila melanogaster (D. melanogaster) is an ideal model for studying the molecular mechanisms behind biological phenotypes, including human diseases. In this study, we collected human and D. melanogaster miRNA as well as known human disease-related genes. In total, we identified 136 human disease-related miRNA that are orthologous to 83 D. melanogaster miRNA by mapping “seed sequence”, and 677 human disease-related genes that are orthologous to 734 D. melanogaster genes using the DRSC Integrative Ortholog Prediction Tool Furthermore, we revealed the target relationship between genes and miRNA using miRTarBase database and target prediction software, including miRanda and TargetScan. In addition, we visualized interaction networks and signalling pathways for these filtered miRNA and target genes. Finally, we compiled all the above data and information to generate a database designated DHDD This is the first comprehensive collection of human disease-related miRNA and their targeting genes conserved in a D. melanogaster database. The DHDD provides a resource for easily searching human disease-related miRNA and their disease-related target genes as well as their orthologs in D. melanogaster, and conveniently identifying the regulatory relationships among them in the form of a visual network.

Published: September 2018

9,9-dimethylfluorenyl-2-phosphonic acid 1 was reacted with manganese nitrate tetrahydrate to produce under hydrothermal conditions the crystalline manganese phosphonate Mn(H2O)2[O2(OH)PC15H13]2·2H2O which crystallize in the P21/c space group. This compound is a rare example of Mn-phosphonate material featuring isolated chains. The interactions between these chains containing the 9,9-dimethylfluorenyl moieties, result from Van der Waals interactions involving the fluorene ligands and C···H–C hydrogen bonds as revealed by Hirshfeld Surfaces. This material features antiferromagnetic exchange interactions as revealed by the magnetic susceptibility as a function of the temperature.

Published: September 2018

Atropine and orthokeratology (OK) are both effective in slowing the progression of myopia. In the current study, we studied the combined effects of atropine and OK lenses on slowing the progression of myopia. This retrospective study included 84 patients who wore OK lenses and received atropine treatment (OA) and 95 patients who wore OK lenses alone (OK) for 2 years. We stratified patients into low (<6 D, LM) and high (≥6 D, HM) myopia groups, as well as two different atropine concentrations (0.125% and 0.025%). Significantly better LM control was observed in OA1 patients, compared with OK1 patients. Axial length was significantly shorter in the OA1 group (24.67 ± 1.53 mm) than in the OK1 group (24.9 ± 1.98 mm) (p = 0.042); similarly, it was shorter in the OA2 group (24.73 ± 1.53 mm) than in the OK2 group (25.01 ± 1.26 mm) (p = 0.031). For the HM patients, OA3 patients compared with OK3 patients, axial length was significantly shorter in the OA3 group (25.78 ± 1.46 mm) than in the OK3 group (25.93 ± 1.94 mm) (p = 0.021); similarly, it was shorter in the OA4 patients (25.86 ± 1.21 mm) than in the OK4 patients (26.05 ± 1.57 mm) (p = 0.011). Combined treatment with atropine and OK lenses would be a choice of treatment to control the development of myopia.

Authors: Ye Sunyue , Lee Jung Eun , Stodden David F. , Gao Zan
Published: September 2018

This study was designed to examine the effectiveness of a combined exergaming and physical education (PE) program on children’s motor skill competence (MSC) and health-related fitness (HRF) as compared to traditional PE. A total of 261 second- and third-grade children (127 boys; 8.25 ± 0.66 years for male; 8.29 ± 0.74 years for female; 73.6% non-Hispanic white) participated in the nine-month study from 2012 to 2013. Children were assigned to one of the two groups: (a) intervention group (125 min of alternating PE and exergaming weekly); and (b) comparison group (125-min weekly PE). MSC was assessed via product scores in two locomotor and two object control skills. HRF included the cardiorespiratory fitness, musculoskeletal fitness, and body mass index (BMI). A multivariate analysis of variance (MANOVA) was performed to analyze the effect of the combined exergaming–PE program on children’s MSC and HRF. There were significant group by time interaction effects for BMI, p < 0.01, η2 = 0.20; musculoskeletal fitness, p < 0.01, η2 = 0.13; and object control skills (the comparison group demonstrating greater improvement), p = 0.01, η2 = 0.03. The findings suggest that the combined exergaming program can have a positive effect on children’s BMI and musculoskeletal fitness, indicating that exergaming can be an alternative school-based program to supplement traditional PE.
Spectral Analysis and Parameter Identification of Textile-Based Dye-Sensitized Solar Cells
Authors: Juhász László , Juhász Junger Irén
Published: September 2018

Linearized equivalent electrical-circuit representation of dye-sensitized solar cells is helpful both for the better understanding of the physical processes in the cell as well as for various optimizations of the cells. White-box and grey-box modelling approaches are well-known and they are widely used for standard cell types. However, in the case of new cell types or the lack of deep knowledge of the cell’s physic such approaches may not be applicable immediately. In this article a black-box approach for such cases is presented applied together with spectral analysis. The spectral analysis and the black-box approach were as first validated with a standard glass-based dye-sensitized solar cell and thereafter applied for the characterization of a new type of textile-based dye-sensitized solar cells. Although there are still improvement potentials, the results are encouraging and the authors believe that the black-box method with spectral analysis may be used particularly for new types of dye-sensitized solar cells.

Published: September 2018

The rapid advancements in information and communication technology during the third industrial revolution of the late 20th century has marked the beginning of a new era in the retail sector with the introduction of E-commerce. The dawn of the new century witnessed industry 4.0, revolutionizing all areas of online business by bringing in novel opportunities and possibilities. Despite the progress in technology, the determination of correct pricing on online selling platforms still remains a very complex task. The adoption of big data technology has enabled online sellers to make real-time price changes of high magnitude and proximity. However, with increasing awareness among buyers regarding modern pricing strategies, it is necessary to examine probable changes in consumer behavior when exposed to dynamic pricing scenarios. This study investigates the factors that influence consumer behavior, and their prospective online purchase decisions in a dynamic pricing context, through an exploratory factor analysis approach. A primary research survey was conducted, and 178 samples were finalized for data analysis through a series of web surveys completed by respondents in India. This study identifies, measures and classifies 27 research items into variables, namely shopping experience, privacy concerns, awareness about dynamic pricing, buying strategy, fair price perceptions, reprisal intentions and intentions for self-protection. These seven factors could be used to explain consumer behavior in a dynamic pricing situation.

Authors: Sannikova Aija , Brante Inara
Published: September 2018

The development of social entrepreneurship as a special business type is in its beginning in Latvia, therefore its development conditions have been researched very little. The legislation regulating this type of business activity commences on the 1st April 2018. In order to promote the development of social entrepreneurship and at the same time promote employment opportunities for unemployed persons who are less favoured, persons with disabilities and other socially vulnerable persons, the EU Structural Funds support for the realization of these strategic goals is available for social businesses. The research carried out a comparative analysis of the legal framework regulating social entrepreneurship in the Baltic States and an analysis of economic preconditions and the support system for social entrepreneurship. The present research contributes to research on social entrepreneurship in two aspects: 1) the legal framework distinguishing this business form from others is analysed; 2) economic preconditions for social entrepreneurship as well as its socio-economic goals and the relevant institutional framework in Latvia are analysed. The subject of the research: preconditions and prerequisites for social entrepreneurship. Methods of the research: the monographic method, statistical analysis and comparative analysis.
Variable Nature of Magnetically Driven Ultra-fast Outflows
Authors: Fukumura Keigo , Kazanas Demosthenes , Shrader Chris , Behar Ehud , Tombesi Francesco , Contopoulos Ioannis
Published: September 2018

Among a number of active galactic nuclei that drive ionized outflows in X-rays, a low-redshift (z = 0.184) quasar, PDS 456, is long known to exhibit one of the exemplary ultra-fast outflows (UFOs). However, the physical process of acceleration mechanisms is yet to be definitively constrained. In this work, we model the variations of the Fe K UFO properties in PDS 456 over many epochs in X-ray observations in the context of magnetohydrodynamic (MHD) accretion disk winds employed in our earlier studies of similar X-ray absorbers. We applied the model to the 2013/2014 XMM-Newton/NuSTAR spectra to determine the UFO’s condition; namely, velocity, ionization parameter, column density, and equivalent width (EW). Under some provisions on the dependence of X-ray luminosity on the accretion rate applicable to near-Eddington state, our photoionization calculations, coupled to a 2.5-dimensional MHD-driven wind model, can further reproduce the observed correlations of the UFO velocity and the anticorrelation of its EW with the X-ray strength of PDS 456. This work demonstrates that UFOs, even without radiative pressure, can be driven as an extreme case purely by magnetic interaction while also producing the observed spectrum and correlations.
Diverse Protoplanetary Disk Morphology Produced by a Jupiter-mass Planet
Authors: Bae Jaehan , Pinilla Paola , Birnstiel Tilman
Published: September 2018

Combining hydrodynamic planet–disk interaction simulations with dust evolution models, we show that protoplanetary disks with a giant planet can reveal diverse morphology in (sub)millimeter continuum, including a full disk without significant radial structure, a transition disk with an inner cavity, a disk with a single gap and a central continuum peak, and a disk with multiple rings and gaps. Such diversity originates from (1) the level of viscous transport in the disk, which determines the number of gaps a planet can open; (2) the size and spatial distributions of grains determined by the coagulation, fragmentation, and radial drift, which in turn affects the emissivity of the disk at (sub)millimeter wavelengths; and (3) the angular resolution used to observe the disk. In particular, our results show that disks with the same underlying gas distribution can have very different grain size/spatial distributions and thus appearance in continuum, depending on the interplay among coagulation, fragmentation, and radial drift. This suggests that proper treatments for the grain growth have to be included in models of protoplanetary disks concerning continuum properties and that complementary molecular line observations are highly desired in addition to continuum observations to reveal the true nature of disks. The fact that a single planet can produce diverse disk morphology emphasizes the need to search for more direct, localized signatures of planets in order to confirm (or dispute) the planetary origin of observed ringed substructures.

Écrire ensemble : un défi au service de la construction d’une posture auctoriale
Authors: Raulet-Marcel Caroline
Published: September 2018

Dans la perspective des programmes de 2015, l’article analyse un projet d’écriture collective mené durant l’année 2013-2014 en cycle 3 d’école primaire, en montrant en quoi certaines des récentes préconisations ministérielles entérinent le travail déjà engagé sur le terrain sous l’impulsion des recherches en didactique de l’écriture. Il s’agit d’insister tout particulièrement sur les enjeux et les modalités d’un dispositif peu détaillé dans les programmes : l’écriture collective. L’instauration d’une communauté de scripteurs est un puissant levier dans l’émergence d’une posture d’auteur collective et singulière. Le travail proposé aux élèves ouvre un espace de dialogue créatif et réflexif au sein de la classe, dialogue entre pairs mais aussi dialogue avec les œuvres littéraires. Les interactions suscitées par les phases de création collective rendent possible mais aussi visible un processus d’écriture-réécriture très riche, à travers lequel se révèle et se forge la conscience esthétique et stylistique des élèves.

Exploring the Factors Influencing Customers Purchase Intention in Online Shopping
Authors: Khanam Fahima
Published: September 2018

Online shopping has increasingly become popular in Bangladesh with the introduction of globalization. Many people, specifically the younger generation, are purchasing various types of products every day online as it is convenient and saves time. Consumers are influenced to purchase online as a result of many factors including time-savings, fast delivery, ease of the transaction, and a website's user friendliness, and many more. The consumer evaluation is important to explore why a consumer intends to purchase online. The present study is an attempt to determine the factors that influence consumers' online shopping in Dhaka. Through this process, this study attempts to identify the critical factors that influence consumers' online shopping in Dhaka and to evaluate the association between these factors and consumers' online shopping habits. It also tries to determine the importance of these factors on consumers' online purchasing habits and to identify problems and suggest possible recommendations. The factors that are being considered include convenience factors, psychological factors, promotional factors, technical factors, and motivational factors. Each factor has some distinct variables. Convenience factors include less time, home delivery, and ease of transaction. Psychological factors include domain specific innovativeness, and opinion of friends and peers. Promotional factors include online ads, and social media exposure. Technical factors include user-friendliness of websites, and display of product details. Motivational factors encompass utilitarian and hedonic values. For this study the Multiple Regression Analysis Model was used. A structured questionnaire survey was conducted on 120 consumers to obtain consumers' opinion regarding how their purchase habits are sparked by different factors. The results reveal that only the home delivery system and utilitarian value of online shopping makes customers consider purchasing online. The other important influences were opinion of friend and peers, social media exposure, and display of product details. This study can hopefully shed some new insights into consumers' online purchasing habits.

This article presents a method for the rough set which attributes priority arrangement of cancellations in the life insurance. The number of canceled documents on the rise plus they're oscillatory and also the rates of cancellations in constant fluctuation, which requires searching in the problem of cancellations of this document, needs to be investigated in the future. It is obvious that these cancellations negatively affect the result operations of insurance companies. The article identifies the most important variables that affect the rates of cancellations and so as to reach solutions that lead to reducing the number of canceled documents by using the Rough model. The rough model was used to identify the determinants of cancellations in the life insurance of the Egyptian insurance market, so as to reach solutions that lead to reduce the number of canceled policies and find solutions to them. These findings prove that the most important factors that affect the cancellations for insurance policies are policy premiums, insurance period and age of policyholders, respectively.
Establishing the Criteria for the Quality of Elderly Medical Care From the Multiple Perspectives
Authors: Lee Wan-I , Chen Chun-Chi , Huang Yu-Bin
Published: September 2018

In 1993, Taiwan has transformed into an aged society. Compared with general patients, older patients differ considerably in body functionality, mentally, and mobility-wise. The primary customers of medical institutions are adult patients in Taiwan, and the needs of older patients are often ignored; however, older patients visiting the case hospital in this study accounted for nearly 30% of the total number of outpatients. This indicates that the needs of older patients are a matter requiring the serious attention of medical personnel. This is a common issue for all countries that were entered an aging structure of the population. This study investigated the attention paid by supervisors and medical personnel involved with medical decisions to the quality of medical services received by older outpatients. An analytic hierarchy process (AHP) was employed to interview 10 experts in older medical care providing age-friendly medical care at the case hospital, medical staff including senior physicians, nursing department supervisors, administration department supervisors, and certified managers. The results indicate that the supervisors and medical personnel considered the “communication and services” provided to older patients during their medical treatments to be the most crucial factor in their treatment process, rating it twice as important as the next most important criteria, the care process and physical environment. Medical personnel paid great attention to communicate with and servicing older patients; listening to their needs and concerns was deemed the most critical, followed by being able to empathize with them to solve problems. Asking patients about their problems when they visited the hospital was considered the most crucial aspect of the care process; in the physical environment, it was spatial planning and traffic flow design. The results of this study enable other countries' medical institution managers and relevant competent authorities to gain insight into the attention paid by front-line employees in promoting age-friendly medical care. If supervisors and medical personnel involved with medical decisions share a similar attitude toward promoting medical service quality, government authorities and medical institutions can implement and enhance an age-friendly medical treatment environment for older patients, as well as increase quality of patient-centered medical services.

Published: September 2018

The use of pricing a model's insurance derivatives in corporate risk management, particularity in insurance has grown rapidly recently. Financial prices for insurance reflects equilibrium relationships between risk and return or, minimally, avoid the creation of arbitrage opportunities. The major objective of this article is to provide evidence that in the Egyptian insurance market during the period 2002-2013, using Black-Scholes model, there was a transfer of wealth from policyholders to insurance companies via overvaluation of insurance premiums. This contribution may have some crucial implications in terms of the “fairness” of pricing insurance contracts.
On Solving the Multi-Objective Software Package Upgradability Problem
Authors: Aribi Noureddine , Lebbah Yahia
Published: September 2018

Free and open source software (FOSS) distributions are increasingly based on the abstraction of packages to manage and accommodate new features before and after the deployment stage. However, due to inter-package dependencies, package upgrade entails challenging shortcomings of deployment and management of complex software systems, inhibiting their ability to cope with frequent upgrade failures. Moreover, the upgrade process may be achieved according to some criteria (maximize the stability, minimize outdated packages, etc.). This problem is actually a multi-objective optimization problem. Throughout the article, the authors propose a Leximax approach based on mixed integer linear programming (MILP) to tackle the upgradability problem, while ensuring efficiency and fairness requirements between the objective functions. Experiments performed on real-world instances, from the MANCOOSI project, show that the authors' approach efficiently finds solutions of consistently high quality.

Authors: Nasution Feldiansyah Bakri , Bazin Nor Erne , Rosalyn Rika , Hasanuddin Hasanuddin
Published: September 2018

In the process of public policymaking, it is recommended to use system dynamics (SD) and Big Data in e-government. SD could assist in viewing problems in complex system holistically, while Big Data in e-government is for collecting data and information which are used for developing model of system dynamics and its equations. On this occasion, partial least square – structural equation modeling (PLS-SEM) is used to validate the relationship between public policymaking (PP), system dynamics (SD) and Big Data in the e-government. Brief explanation about survey and PLS-SEM are discussed. Some of the statistic parameters, such as path coefficients or beta coefficients, P values, R Square coefficients and effect size are shared and analyzed. These terms are parameters for us to see how strong the relationship between PP, SD and Big Data.

The current context reflects education as a profound social act, through which the individual discovers his own personality, he manifests his social aspirations and ideals, tangling and determining the evolution of social events. More and more young people face major challenges in terms of skills in a permanently changing world. The skills gap is growing between developing countries and developed countries and there will be major social, economic and political repercussions. This article focuses on identifying the role that school resources has on the educational performance of pupils in the digital era. For collecting the data, a direct survey was used as a method of collecting information, based on a questionnaire of 374 pupils from high schools in Dambovita County, Romania. While the future is always uncertain, education systems should be based on the design of innovative, effective learning environments, encouraging well-organized cooperative learning where learners actively engage and develop a good understanding of their own learning practices, focusing on student motivation and differentiation according to previous knowledge.
An Analysis of the Internal Consistency of the New Accounting Standard for Virtual Currencies in Generally Accepted Japanese Accounting Principles
Authors: Tsuji Mineo , Hiraiwa Mitsuki
Published: September 2018

While there is no specific guidance in IFRS or US GAAP on accounting for virtual currencies, the ASBJ issued the PITF on the Accounting for Virtual Currencies under the PSA on March 14, 2018 as part of J-GAAP. The standard subscribes that, if an active market exists for the virtual currency, such a virtual currency should be measured using the market price at the balance sheet date, and any difference between the carrying amount should be recognized as a gain or loss. This article examines logically the internal consistency of the accounting information of virtual currencies subscribed by the standard in J-GAAP and between the standard and IFRS. The results indicated that it is appropriate to present virtual currencies at the recoverable amount as in the case of other monetary assets in J-GAAP and that there are no significant differences internationally between the standard and the IFRS.
A Design-Time Semi-Automatic Approach for Obfuscating a Business Process Model in a Trusted Multi-Cloud Deployment
Authors: Nacer Amina Ahmed , Goettelmann Elio , Youcef Samir , Tari Abdelkamel , Godart Claude
Published: September 2018

To enjoy the benefits of cloud computing, organizations managing complex business processes want to outsource their processes. However, as such processes express their know-how and because of the nature of the cloud, they are still reluctant to do so. To prevent such a know-how exposure, this article proposes a design-time approach for obfuscating a BP model by splitting its model into a collaboration of BP fragments semantically equivalent to the initial BP. This breaking down renders the discovery by cloud providers of-the-deep content of a critical fragment, and more of the whole process, much harder when these fragments are deployed in a multi-cloud context. While existing contributions on the topic of BP obfuscation remain at the level of principles, the authors propose an algorithm supporting automatically such a BP model transformation. The approach is validated against an obfuscation metric introduced in the article. The obtained results show that the authors' algorithm generates BP fragment with a high obfuscation level, contributing to protect BP know-how when deployed in a multi-cloud context.

Statistical Primer for Athletic Trainers: Understanding the Role of Statistical Power in Comparative Athletic Training Research
Authors: Lininger Monica R. , Riemann Bryan L.
Published: September 2018

Objective: 

To describe the concept of statistical power as related to comparative interventions and how various factors, including sample size, affect statistical power.

Background: 

Having a sufficiently sized sample for a study is necessary for an investigation to demonstrate that an effective treatment is statistically superior. Many researchers fail to conduct and report a priori sample-size estimates, which then makes it difficult to interpret nonsignificant results and causes the clinician to question the planning of the research design.

Description: 

Statistical power is the probability of statistically detecting a treatment effect when one truly exists. The α level, a measure of differences between groups, the variability of the data, and the sample size all affect statistical power.

Recommendations: 

Authors should conduct and provide the results of a priori sample-size estimations in the literature. This will assist clinicians in determining whether the lack of a statistically significant treatment effect is due to an underpowered study or to a treatment's actually having no effect.
Vasectomies of male African elephants as a population management tool: A case study
Authors: Zitzer Heike R. , Boult Victoria L.
Published: September 2018

Elephant populations in South Africa are largely confined to fenced reserves and therefore require continued management to prevent high elephant densities that may cause habitat degradation. Growing human populations surrounding these reserves limit the possibility for wildlife range expansion, adding socio-economic considerations to the growing list of challenges reserve managers must contend with. Often, reserves have therefore opted to manage elephant population growth using various contraceptive methods to reduce birth rates, with lethal control acting as a last resort.Reserve owners at the Pongola Game Reserve South in northern KwaZulu-Natal opted to vasectomise the oldest male elephants to limit elephant population growth. Besides the reduction in birth rates, vasectomies were anticipated to have minimal impacts on behaviour. This study aimed to examine behavioural implications of treatment by monitoring musth, dominance and social behaviours of vasectomised males.Physical and behavioural observations of vasectomised males were recorded using instantaneous scan sampling and continuous focal samples of study individuals between 2011 and 2016. These data were also collected for non-treated adolescent males, with which to substantiate potential impacts of vasectomies.This case study has revealed that the behaviour of the vasectomised males was not influenced by vasectomies: musth was displayed as anticipated in the oldest males; a linear dominance hierarchy was maintained, headed by the oldest individual, and association patterns with female groups remained intact. Further, the younger non-treated males fell in line with the overall dominance hierarchy.This unique post-treatment study supports the use of vasectomies as a relatively cost-effective (one-off treatment), low-risk and successful tool for the management of elephant population growth, and an option which is preferable to both lethal control and hormonal contraceptives. Further research to establish the impacts of vasectomies on female behaviour and population dynamics is recommended.

Published: September 2018

Coexistence of left ventricular true and pseudoaneurysm together is although rare but can be a possible sequelae of ventricular remodeling postmyocardial infarction. True aneurysm can be suspected on the basis of persistent ST-segment elevation on electrocardiogram several weeks after myocardial infarction while pseudoaneurysm can only be diagnosed after a comprehensive echocardiography examination. We describe a rare case of true aneurysm of the left ventricle apex and pseudoaneurysm of midanterior septum wall confirmed by myocardial contrast echocardiography.

Abstract. The aim of the study was to analyse the sex ratio of American mink litters in relation to dam's age, gestation length, and time interval between the first and second mating. The observations were carried out on a mink farm located in northern Poland. The analysis involved litters of 207 females, aged 1 (n=107) and 2 years (n=100), which successfully raised all the born kits. The sex of the offspring was identified on weaning. The kits were assigned to groups according to their dam's gestation length, mating date, and first-to-second mating interval. It was found that female kits quantitatively predominated over male offspring. Longer pregnancies, delayed mating time, and greater interval between the first and second mating was accompanied by a higher number of female births in relation to male births.
Novel Surgical Approach to Segmental Bone Transport Using a Magnetic Intramedullary Limb Lengthening System

Published: September 2018

Posttraumatic bone defects (BDs) remain a difficult complication for orthopaedic surgeons. Surgical goals in these reconstructive cases are to create stable limb fixation, maintain limb length, and provide adequate soft-tissue coverage. Historically, surgical approaches in these cases have required the use of an external fixator, which is associated with several postoperative complications. A plate-assisted bone segment transport (PABST) technique using a magnetic limb lengthening system eliminates the need for an external fixator and is effective for these reconstructive cases. A 51-year-old male patient presented as a category I trauma after a motorcycle collision. Osseous injury was defined as Gustilo-Anderson type IIIB distal tibia and fibula fracture (AO 42-C2). After fixation failure, the PABST technique was performed using a magnetic intramedullary limb lengthening system. Radiographic union was achieved 18 months postoperatively. This innovative surgical technique is effective in treating posttraumatic BDs without the need for limb shortening or the use of an external fixator. PABST has the potential to decrease postoperative complications in BD reconstructive cases using all-internal technology designed for limb lengthening. PABST, in this instance, uses a magnetic intramedullary nail that is controlled with a hand-held external remote to allow for precise, adjustable, and bidirectional bone segment transport.
“If He/She Had Been Like the Rest of Us”. How Do Young People Describe Their Schoolmates Who Are Different from Others in the Group?

Published: September 2018

The article examines issues related to peer interactions and group joining in upper secondary schools in Finland. The study elaborates on how young people describe students who are left out/excluded or who remain outside the social networks. The study also elucidates on how a student can join the group. The research is motivated by the current educational ethos, which emphasizes inclusion and tolerance. The data were collected from an upper secondary school and vocational and technical institute. The students were asked to recall the prior high school year and write an essay on the topic. A total of 49 students wrote about their memories. The data were analyzed using inductive content analysis, and the study found that students are either excluded or included due to the social skills they possess. Those who do not exhibit the same approach to being in a group will stay on the sidelines. The essays also described factors that connect students, such as hobbies and leisure activities. Similarity in many external factors (e.g., the family’s economic situation) unites students. Contrary to expectations, young people described themselves, and not just others, as outsiders.
Numerical Blow-up for A Heat Equation with Nonlinear Boundary Conditions

Published: September 2018

We study numerical approximations of solutions of a heat equation with nonlinear boundary conditions which produce blow-up of the solutions. By a semidiscretization using a finite difference scheme in the space variable we get a system of ordinary differential equations which is an approximation of the original problem. We obtain sufficient conditions which guarantee the blow-up solution of this system in a finite time. We also show that this blow-up time converges to the theoretical one when the mesh size goes to zero. We present some numerical results to illustrate certain point of our work.

Essential oils from aromatic plants of Ledum palustre L. and Mentha piperita L. were extracted using steam distillation and the antimicrobial effects were evaluated alone and in combinations against food-borne pathogens of Gram-positive and Gram-negative bacteria and food related-yeasts (Bacillus subtilis, Escherichia coli, Saccharomyces cerevisiae, Schizosaccharomyce spombe, and Geotrichum candidum). Essential oils from two aromatic plants used in this study showed the antimicrobial activity against bacteria and yeast, which was found to be concentration dependent. The effects of Ledum palustre L. and Mentha piperita L. plants essential oils against yeast and Gram-negative bacteria at concentrations of 0.5 ul/ml and 0.25 ul/ml extended lag phase or adaptation phase by 48 hours, respectively. Gram-positive bacteria were found to be susceptible to the studied two plants essential oils. When the effects of antimicrobial activity of two essential oils were tested in combination against bacteria and yeast in vitro, the MIC value was in the range of 0.125-0.5 ul/ml and showed synergistic activity against E.coli and additive values against B.subtilis and S.cerevisiae.
Aspectos relevantes no uso da pesquisa-ação na engenharia de produção
Authors: Miguel Paulo Cauchick
Published: September 2018

A natureza de uma pesquisa-ação estabelece que uma investigação em engenharia de produção seja conduzida em conjunto com aqueles que cooperam com o estudo, geralmente profissionais da indústria. A pesquisa-ação é uma abordagem metodológica que objetiva realizar uma ação e gerar conhecimento ou teoria em relação às questões de pesquisa. Essa categoria de abordagem é aplicada em várias áreas do conhecimento, particularmente na engenharia de produção e gestão de operações. No entanto, apesar dos seus benefícios, ela não é extensivamente aceita como uma sólida abordagem metodológica, mas pode ser considerada uma fonte relevante para extensão ou refinamento da teoria, quando é conduzido um trabalho baseado em ações na indústria. Nesse contexto, apresenta-se neste trabalho uma síntese bibliográfica sobre a pesquisa-ação e se enfatizam alguns levantamentos na adoção desse tipo de abordagem na engenharia de produção e gestão das operações. Finalmente, no estudo apontam-se fatores relevantes quando se conduz uma pesquisa-ação.
Constructing a concept of number
Authors: Overmann Karenleigh A.
Published: September 2018

Numbers are concepts whose content, structure, and organization are influenced by the material forms used to represent and manipulate them. Indeed, as argued here, it is the inclusion of multiple forms (distributed objects, fingers, single- and two-dimensional forms like pebbles and abaci, and written notations) that is the mechanism of numerical elaboration. Further, variety in employed forms explains at least part of the synchronic and diachronic variability that exists between and within cultural number systems. Material forms also impart characteristics like linearity that may persist in the form of knowledge and behaviors, ultimately yielding numerical concepts that are irreducible to and functionally independent of any particular form. Material devices used to represent and manipulate numbers also interact with language in ways that reinforce or contrast different aspects of numerical cognition. Not only does this interaction potentially explain some of the unique aspects of numerical language, it suggests that the two are complementary but ultimately distinct means of accessing numerical intuitions and insights. The potential inclusion of materiality in contemporary research in numerical cognition is advocated, both for its explanatory power, as well as its influence on psychological, behavioral, and linguistic aspects of numerical cognition.

The ethics in bank’s business is a combination of policies and practices that can be used to satisfy the interests of different stakeholders. The paper analyzes the banks’ business ethics in Bosnia and Herzegovina by identifying the level of trust between clients and banks. For the purpose, we used a dual approach measuring the application of general bank’s ethics principles, principles of respect for human rights, sales and principles of using and sharing information. The aim of the paper is to examine and evaluate the application of the principle of bank’s business ethics and to compare the attitudes of different groups of respondents. We begins with the hypothesis that there are no significant differences in the attitudes of clients and bank employees on the application of the banking ethics principles in establishing and maintaining business relationships with clients. For the purpose and using structured questionnaire, we conducted primary research on two samples of respondents, clients and employees. The collected data were tested using a two-tailed ‘z-score’ test. The results indicate the significant statistical differences in the attitudes of testing two normally distributed samples. Promotion of business ethics in order to align client and employee r equirements in B&H banks is recommended for two levels of capacity development: the development a system for generating initial ideas by sales staff capable to recognize client needs and improving the cRM system in B&H banks.
