Published: June 2019

Purpose of Study: In this paper, institutions of agreements (mediation) in criminal proceedings in various states were investigated regarding the history of their occurrence and development. The aspects under the study included features related to the use of institutions of agreement in individual countries (USA, Canada, Germany, Russia, Moldova, etc.); the regulatory framework of these countries, statistics on the use of institutions of agreements (mediation), as well as programs used as mediation. Methodology: In the present study, general scientific, as well as special methods and provisions of dialectics were used. In the course of the study, private scientific methods were also used including historical-legal, formal-legal, formal-logical, systemic, and comparative. Results: Currently, the new legal institution of agreement (mediation) is actively developing in the global legal system, contributing to resolving the conflict without holding a trial and just by holding peace negotiations and concluding an agreement with the accused. This institution was initially established in countries with the Anglo-Saxon legal system (USA, UK), and then was developed in countries with a continental legal system (RF, Moldavia, Kazakhstan). Implications/Applications: The mediation is considered to be a convenient approach for resolving conflicts, since it is built on the mutual agreement of two confrontational parties, and it will continue to further develop worldwide and will be included in the legislation of those countries where it has not been fixed yet.

Published: June 2019

Este artigo contribui com a análise estática, dinâmica e a verificação experimental de um retificador Cuk bridgeless monofásico operando no modo decondução descontínuo (DCM). A ausência de uma ponte retificadora de entrada e a presença de apenas dois semicondutores de potência no caminho da correntereduz as perdas em comparação com o retificador Cuk convencional. Os dois interruptores são controlados simultaneamente através de um único pulso de comando, o que reduz a complexidade do circuito de acionamento. O alto fator de potência é naturalmente obtido por meio do DCM, sem a necessidade do controle da corrente de entrada. De modo a validar a análise teórica desenvolvida, foi construído um protótipo de laboratório de 300 W, com tensão eficaz de entrada de 220 V e tensão de saída de 96 V. São demonstrados resultados experimentais com malha de controle da tensão de saída do conversor, o qual, em potência nominal, apresentou um rendimento de 93,3 % e uma corrente de entrada com THD menor que 3 %.
Do consumers talk about the software in my product? An Exploratory Study of IoT Products on Amazon
Authors: Srisopha Kamonphop , Boehm Barry , Behnamghader Pooyan
Published: June 2019

Consumer product reviews are an invaluable source of data because they contain a wide range of information that could help requirement engineers to meet user needs. Recent studies have shown that tweets about software applications and reviews on App Stores contain useful information, which enable a more responsive software requirements elicitation. However, all of these studies' subjects are merely software applications. Information on system software, such as embedded software, operating systems, and firmware, are overlooked, unless reviews of a product using them are investigated. Challenges in investigating these reviews could come from the fact that there is a huge volume of data available, as well as the fact that reviews of such products are diverse in nature, meaning that they may contain information mostly on hardware components or broadly on the product as a whole. Motivated by these observations, we conduct an exploratory study using a dataset of 7198 review sentences from 6 Internet of Things (IoT) products. Our qualitative analysis demonstrates that a sufficient quantity of software related information exists in these reviews. In addition, we investigate the performance of two supervised machine learning techniques (Support Vector Machines and Convolutional Neural Networks) for classification of information contained in the reviews. Our results suggest that, with a certain setup, these two techniques can be used to classify the information automatically with high precision and recall.

The Life History of Performance Anxiety in Japanese Professional Orchestral Players: A Case Series
Authors: Sutani Shizuka , Akutsu Taichi
Published: June 2019

This study investigated the life history of performance anxiety in Japanese orchestral players. Twenty-nine players in a Japanese orchestra completed the State Trait Anxiety Inventory (STAI) backstage immediately following a concert. Five players with the longest experience in the orchestra
were selected for further data collection. Based on the results of the STAI, the researchers conducted semi-structured interviews to construct the life history of these 5 players in relation to their performance anxiety. In the process of narrative construction, a commentary from a psychiatrist
was integrated to examine the underlying personality and ability to cope with the anxiety, as well as the contextual influences in the participants’ life-long learning experiences. Results indicated that the anxiety was present throughout the players’ musical development, from
childhood and into professional status. However, their performance anxiety was reduced and transformed over time. The study also revealed that these 5 players tended to experience anxiety when playing with others and in large groups. The subjects tended to consider anxiety as a necessary psychological
state-of-mind to maintain a professional level of performance and to deal with the uncertainty of group playing. Finally, the individual players found their own specific methods to reduce anxiety by focusing on musical expression and/or simply by gaining experience. Instead of generalizing
the result, this study explored the life history of performance anxiety in this series of individual players in Japan.

Authors: King Benjamin , Berg Lloyd , Koenig Jessica , Adair J Jade , Tirado Carlos
Published: June 2019

OBJECTIVE: Popular (i.e., nonclassical) musicians have higher rates of depression, anxiety, and suicide than the general population. Occupational and financial stress have been suggested to be social determinants of musician mental health burden. A pilot study was conducted to assess
the internal consistency and test-retest reliability of a revised measure of popular musician occupational stress and compare the results to those of other, previously validated instruments used in the same survey. METHODS: An online survey was emailed to a convenience sample of 150 musicians
who had formerly accessed mental health services through a non-profit organization in Austin, Texas. The survey included a revised Musician Occupational Stress Scale (MOSS), a measure of financial stress, and instruments to screen for clinically significant depression, anxiety, and alcohol
misuse. RESULTS: Forty musicians (26.7%) completed the initial survey and 19 completed a repeat survey 2 weeks later for the test-retest comparison. Internal consistency coefficients for individual instruments ranged from 0.86–0.92. The piloted MOSS demonstrated good internal consistency
(Cronbach’s α=0.91; one-sided 95% CI ≥0.88) and test-retest reliability (r=0.86; p<0.0001). The MOSS also showed reasonable construct validity, correlating well with a single question of perceived occupational stress (ρ=0.46; p<0.001) over career satisfaction (ρ=–0.09;
p>0.05). CONCLUSION: The individual, construct-specific measures included in this survey all demonstrated good internal consistency and test-retest reliability on examination. While the results are preliminary due to the small sample size, the MOSS psychometrically performed at a level
equal to or better than other widely used and well-validated measures included in this survey.

Using internship placements to road test threshold learning outcomes for environment and sustainability
Authors: Whelan Michael Barry , Reichelt-Brushett Amanda
Published: June 2019

In 2015 the threshold learning outcomes (TLOs) for Australian bachelor degree graduates in the discipline of Environment and Sustainability were released.  This study road tested the Environment and Sustainability TLOs in the workplace via environmental science students’ internship placement. The study, which incorporated surveys of host-supervisors, students and teaching staff, was conducted over four years. The surveys enabled comparisons between the performance expected of a new graduate by employers with the level of performance students achieved while on placement. Overall, hosts expect new graduates to be ‘Capable’ performers (2.8 on a 5 point scale). Host-supervisors also rated the overall performance of interns as ‘Capable’ (3.4/5). Expected performance of a new graduate for individual TLOs was compared with the performance of interns. Students exceeded the expectations of host-supervisors for all TLOs. In contrast, teaching staff rated the performance of students lower than students themselves and host-supervisors. Fundamental differences in the way students are assessed in the workplace and the classroom may account for the difference in perceived student performance. The results of the surveys can be used as evidence that the degree is meeting the needs of industry and for graduates to undertake professional work in the Environment and Sustainability discipline. The methodology has the potential to be used in any discipline that has published TLOs. The authors recommend that the Australian Qualifications Framework is reviewed and a rubric that describes student behaviour is used rather than vague terms such as ‘well developed’.

Authors: Tekin Yadel Hazır , Hayran Yeliz
Published: June 2019

Background: The aim of this study was to evaluate the fracture resistance and wear amounts of different zirconia and metal-supported ceramics.
Methods: Katana, Prettau, Zenostar, InCoris TZI, BruxZir and porcelain fused to metal (PFM) were used (n=10). All samples were aged via thermal-cycling. Wear test was performed in chewing simulator. Occlusal wear was measured via a 3D laser-scanner. Fracture resistance of samples was determined via a universal testing machine. For statistics, One-Way ANOVA and Tukey were used.
Results: PFM had the highest wear area, and differences among groups were significant. BruxZir, Zenostar, and InCoris TZI had lower wear than Prettau and Katana, but the differences were not significant. All groups had similar wear volume. Fracture resistance was significantly lower in Katana and PFM than Zenostar, InCoris TZI, and Prettau. The difference between Katana and PFM was significant. BruxZir samples were not broken even with the highest force applied.
Conclusions: Monolithic zirconia ceramics showed superior wear behavior compared to PFM in terms of wear area; however 3D wear measurements were similar. Fracture resistance was also higher in zirconia except for Katana, which had the lowest value. BruxZir was the hardest material with the lowest wear and highest fracture resistance.

Published: June 2019

Background: Clinical education is a vital part of the curriculum in medical education. Some studies showed that dominant values changed during education, and some negative values might replace positive ones. In this regard, this study aimed to explore various aspects of the barrier to professionalism in clinical medical education. By describing the experiences that interns had as educational outcomes during their years of education, and in the clinical setting of their patients, efforts were made to obtain an image of what was happening and to take some steps towards reducing these shortcomings and move towards training more efficient physicians with higher qualifications by providing necessary strategies to educational planners.
Method:
This was a qualitative study conducted with the content analysis method. The research population consisted of the students of Iran's two most important medical schools in 2018. A total of 34 interviews with 23 participants were done, each lasting 30 to 90 minutes and data analysis performed with Atlas ti7 software.
Results:
Two hundred forty-eight original codes were extracted from the research data, which were classified under the theme of "Academic Exhaustion" and the four following categories: "stressful environment, "human conflict," "Poor Inter professional collaboration," and "emotional exhaustion."
Conclusion:
What was understood from all categories was called "Academic Exhaustion." According to the results of this study, it can be admitted that having full knowledge of the factors influencing professionalism from the viewpoint of stakeholders can improve the environmental and organizational conditions to prevent professional misconduct.

Acmella oleracea (L.) R.K. is a native Amazon vegetable, known as jambu, which is widely used in regional cuisine and has aroused the interest of the pharmaceutical and cosmetic market. Thereby, this work aimed to study the effect of different soil water tensions and nitrogen rates on Jambu cultivation in the State of Pará. The experiment was conducted in a greenhouse for 30 days in 2016 testing Jamburana cultivar in a 10 × 10 cm spacing in the experiment. The experimental design was based on randomized blocks in a 4 × 4 factorial scheme with three replications. The treatments consisted of four soil water tensions (12, 18, 24 and 30 kPa) adjusted using drip irrigation, and four doses (0, 50, 100 and 150 kg ha-¹) of nitrogen. The analyzed variables were fresh mass, plant height, productivity and water use efficiency. There was no interaction between soil water tensions factors and nitrogen rates for all variables. The results showed that the best water tension in the soil and nitrogen dose that provided better development and productivity of jambu were 18 kPa and 79 kg ha-¹, respectively.

Published: June 2019

Fertilizer application can enhance the nutritional value of plants, such effects being influenced by the presence of arbuscular mycorrhizal fungi (AMF). Nutrients × AMF interactions are well-known for variety of elements but very little has been addressed on biofortification of selenium (Se) in plants grown in tropical soils. The purpose of this study was to evaluate the effect of Se application and AMF inoculation on growth and micronutrient contents on soybean plants as forage grass. The experiments were conducted in a completely randomized factorial design with five Se doses (0.0, 0.5, 1.0, 2.0 and 3.0 mg kg-1 for soybean plants, and 0.0, 0.5, 1.0, 3.0 and 6.0 mg kg-1 for forage plants), with and without AMF inoculation in three replicates. The results showed that soil Se had only slight effect on soybean growth but it caused a two-fold increase on grain yield. However, the growth of forage grass was enhanced by Se application when AMF was present. The AMF inoculation reduced benefit for soybean growth and yield but marked positive effect on forage grass at high doses of Se. Selenium contents in both plants were increased by its application in soil, being such effect proportional to soil applied doses. Selenium application and AMF inoculation had marked effects on micronutrients contents in both soybean plants and forage grass and they may contribute to Se and micronutrient biofortification.

Neutral nanoparticles (NPs) of iron, zinc, copper or their compositions were introduced into nutrient Murashige-Skoog (MS) medium instead of traditional metal salts with/without chitosan supplements to obtain healthy and crop productive plants. Metal NPs concentrations were: Fe NPs (0.06, 0.3, 3.0); Zn NPs (0.016, 0.08, 0.4); Cu NPs (0.004, 0.0008, 0.00016) (mg L-1). Pepper (Capsicum annuum) cultivar LJ-King was grown on modified media in aseptic conditions. After 45 days, root and stem length, root activity, green mass gain and chlorophyll content in leaves were measured. Pepper plants grown on media with metal NPs showed increased root length and activity (for Fe, Zn, Cu NPs and their composition) and chlorophyll content in leaves (for NPs Fe and Cu). However, addition of Chitosan modified the effects. Monitoring of pepper grown on MS with NPs composition (Fe: Zn: Cu as 3.0:1.0:0.004 mg L-1) with electron microscope demonstrated no NPs accumulation in roots, sprouts and leaves.

Published: June 2019

Esta pesquisa avaliou o perfil dos gastos com assistência médica de um conglomerado de empresas com aproximadamente 50 mil trabalhadores, por meio de um levantamento retrospectivo, descritivo, quantitativo e documental. Em 12 meses, o gasto foi de R$ 41.881.573,00 (média mensal per capita de R$ 68,56), sendo as principais despesas: 40,2% internações, 31,2% exames eletivos, 16,7% consultas eletivas. Os índices de utilização de serviços foram: 3,1 consultas / assegurado / ano, 7,42 exames / assegurado / ano, 2,4 exames / consulta, 9,92% internações no ano. Os usuários eram mais jovens que a média nacional, e o padrão de utilização dos serviços estava abaixo dos indicadores divulgados pela ANS, porém acima dos parâmetros do Sistema Único de Saúde. O percentual de gastos com diagnósticos se justifica, em parte, pela baixa remuneração e pouco tempo destinado às consultas, além da prática da medicina defensiva. Esses resultados podem auxiliar no planejamento de ações para aperfeiçoar a indicação de exames, aumentando a eficiência da gestão da operadora de saúde.

Authors: Mahdi Mahmoud Maustafa , Gaddoa A. A.
Published: June 2019

The work of this paper is an investigation to improve the condenser performance of the automobile air conditioning system by enhancing the air-side heat transfer from the condenser through the use of an air guide net installed in front of the condenser face which is basically an aluminum plate having a circular entrance shape for the air passage.  The A/C system was examined under two types of test. The first test was conducted the air guide net, while the second was done with the air guide net. The performances of the A/C system under these tests were compared. For the second type of test, the experiment was carried out with three different size of air guide net, three different circular diameters (2, 3 and 3.5 cm) and a common air passage area. The effect of varying the size of the air guide net and its inclination angle was investigated. The experimental work included five inclination angles (0o, 5o, 10o, 15o and 20o). It was found that the presence of the air guide net caused an improvement in the performance of the A/C system for all sizes and inclination angles.  In addition, the electrical energy consumed by the A/C system without the air guide net was calculated and compared to those obtained for the A/C system with the air guide net. The results manifested that the reduction of the power consumption was enhanced by operating the A/C system with the air guide net.

Authors: Abbas Tahseen Fadhil , Younis Karem Mohsen , Mansor Khalida kadhim
Published: June 2019

Multipoint forming process is an engineering concept which means that the working surface of the punch and die is produced as hemispherical ends of individual active elements (called pins), where each pin can be independently, vertically displaced using a geometrically reconfigurable die. Several different products can be made without changing tools saved precious production time. Also, the manufacturing of very expensive rigid dies is reduced, and a lot of expenses are saved. But the most important aspects of using such types of equipment are the flexibility of the tooling. This paper presents an experimental investigation of the effect of three main parameters which are blank holder, rubber thickness and forming speed that affect the surface integrity for brass (Cu Zn 65-35) with 0.71 mm thickness.

This paper focuses on the development of prediction models for estimation of the product quality. Using Analysis of Variance (ANOVA), surface roughness has been modeled. In the development of this predictive model, blank holder, rubber thickness and forming speed have been considered as model parameters. The mean surface roughness (Ra) is used as response parameter to predict the surface roughness of multipoint forming parts. The data required has been generated, compared and evaluated to the proposed models obtained from experiments.

Taguchi algorithm was used to predict the forming parameters (blank holder, rubber thickness and forming speed) on product roughness in forming process of Brass (Cu Zn 65-35) based on orthogonal array of L9 and finally ANOVA was used to find the optimum parameters that have effect on the product quality.

Authors: Stilp Curt C. , Reynolds Candyce
Published: June 2019

Background: Team-based care has been proposed as a way to utilize rural healthcare resources wisely. Thus, the need to educate healthcare profession students in the fundamentals of rural team-based practice has increased in recent years. Thisstudy  sought to examine student reflections of a rural interprofessional practice and education (IPE) program in an effort to learn how students described their experience and what they valued.Methods and findings: Student reflection journals from a formal rural IPE program were examined for themes related to post-experience values, attitudes, and beliefs. In general, the time spent in rural IPE led to understanding what it means to live and provide care as a team to a rural community. One important new discovery is that social interactions outside formal IPE curriculum are central to achieving programmatic goals.Conclusion: Understanding the significance of rural IPE and how to guide students both inside and outside the clinical setting will help lead the development of future IPE. The findings of this study shed light on what students valued in a rural IPE experience and, thus, have implications for where institutional resources should be concentrated.

Published: June 2019

A mathematics framework was developed to integrate problem-solving that incorporated simulation of real-life problems in the classrooms. The framework coined as the RECCE-MODEL emphasised understanding and thinking with a view on mathematics embedded in real-life. The RECCE which stands for Realistic, Educational, Contextual, Cognitive, and Evaluation encompass the underlying principles of teaching problem solving and guide teachers in planning, designing, developing, and facilitating real-life activity tasks in developing students’ problem-solving competencies in mathematics lessons. It also explores students’ cognitive competency in their application of abstract mathematical knowledge into real-life problems based on students’ developmental status of their thinking and reasoning skills correlating to Meanings, Organise, Develop, Execute and Link (MODEL). This study investigated the affective development of the students through activity tasks developed by the sampled teachers using the principles within the framework. In total, 94 students from two high schools in Brunei Darussalam responded to a students’ questionnaire constructed to address the MODEL aspect of the framework. In particular, the analyses involved the students’ affective competencies that corresponded to a 19-item instrument within the questionnaire.  The findings showed that Brunei high school students have stimulated beliefs and positive attitudes towards non-routine problem-solving in the learning of mathematics. Meanwhile, meaningful activities developed by the teachers encouraged the development of cognitive-metacognitive and affective competencies of the students. The RECCE-MODEL framework paved the way towards understanding the relationships between effective pedagogical approaches and students’ learning, and between attitudes and cognitive abilities, and also for teachers to make better-informed decisions in the delivery of the curriculum.

Beliefs and pedagogical content knowledge (PCK) are two factors influencing teaching practice in the classroom. This research aims to describe the beliefs and PCK of the prospective mathematics teachers and the relationship between the two factors on the teaching practices in the mathematics classroom. Participant in this research includes a prospective teacher who has taken a micro teaching subject and has good communication skill. Data were collected through interview and video analysis on the teaching practice in the classroom. The data obtained were coded, simplified, presented, and triangulated for the credibility and concluded. The result of the research shows that the prospective teachers who hold a constructivist belief view mathematics as a dynamic knowledge which evolves and is regarded as the space of creation for humans. Their beliefs on the nature of mathematics support the belief in the teaching-learning process in mathematics classrooms. Furthermore, a good understanding of the prospective teachers have on the components of the PCK has been sufficient, which can be identified in every step of practical activities in the classroom. More elaboration on the relationship between the belief and PCK is presented in this research.

El estrés laboral docente, y su impacto en la efectividad escolar es un tema relevante y de importancia, tanto científico como social. Estudiar el estrés laboral del magisterio es una necesidad en el contexto educativo pues permite trazar medidas preventivas y de afrontamiento. El contexto de la posmodernidad y de un mundo tecno-globalizado, repercute en este nivel educativo tanto en su misión como en su función social, los trabajadores de educación básica no solo tienen por encargo la formación del niño o adolescente, sino también cubrir los espacios de aprendizaje que la familia no puede suplir unido a las demandas de eficacia y a la influencia de las condiciones de trabajo en la cultura organizacional escolar.

El propósito del presente estudio fue determinar un modelo explicativo que corrobore el efecto moderador del liderazgo transformacional sobre el efecto negativo del estrés laboral sobre la efectividad escolar en los docentes de escuelas de educación básica de Ciudad Guzmán, Jalisco. Se asumió un diseño de investigación de tipo no experimental transversal y con alcance explicativo. Se declara de esta forma, pues se observa el estilo de liderazgo, el estrés laboral y la efectividad escolar, tal como se presentan en el contexto de la educación básica por lo que no se construye ninguna situación, sino que se observan situaciones ya existentes. La metodología es cuantitativa, se utiliza un modelo de moderación a través de la interface process en el programa SPSS.25.

Se evidencia en el presente estudio, que existe, relación –negativa- entre el estilo de liderazgo transformacional y el estrés laboral docente percibido. En el mismo tenor, se muestra como hallazgo la relación negativa entre el estrés laboral y la efectividad escolar percibida. Se demuestra que, a mayor estrés, menor será la percepción de efectividad escolar, por tanto, el resultado avala la necesidad de intervención para reducir el estrés laboral y potenciar la efectividad de las escuelas estudiadas. El liderazgo transformacional constituye un modulador del estrés laboral y la eficacia escolar por lo que se demuestra que directores capaces de influir como modelos en sus trabajadores, con adecuado uso del carisma y tolerancia psicológica, así como con una actitud personalizada y más humana hacia sus trabajadores garantizarán escuelas que resulten menos afectadas por estrés laboral, más efectivas en su misión social, organizacional y, por tanto, más saludables.
Staðnemar og fjarnemar í grunnskólakennaranámi við Menntavísindasvið: Bakgrunnur, viðhorf og áhugi á að starfa við kennslu

Minnkandi aðsókn að kennaranámi og skortur á kennurum veldur talsverðum áhyggjum. Fyrir um aldarfjórðungi var farið í átak til að fjölga réttindakennurum en hlutfall leiðbeinenda hafði verið hátt, einkum á landsbyggðinni. Farið var að bjóða upp á fjarnám og samið var við kennaramenntunarstofnanir um að taka við f leiri nemum. Hlutfall leiðbeinenda lækkaði í kjölfarið og einnig varð efnahagshrunið 2008 til þess að kennarar sneru aftur til starfa í grunnskólum. Nú hefur hlutfall leiðbeinenda hækkað að nýju og óttast er að fjöldi útskrifaðra grunnskólakennara með réttindi haldi engan veginn í við þann fjölda sem hættir störfum, meðal annars vegna aldurs. Brottfall úr grunnskólakennaranámi og hæg námsframvinda veldur einnig áhyggjum. Í þessari rannsókn er dregin upp mynd af bakgrunni grunnskólakennaranema við Menntavísindasvið Háskóla Íslands og kannað hvort munur sé á fjar- og staðnemum. Niðurstöður benda til þess að fjarnemar eigi síður háskólamenntaða foreldra en staðnemar og að börn kennara fari frekar í staðnám en fjarnám. Svipað hlutfall fjarnema og staðnema vinnur með námi en fjarnemar vinna mun f leiri tíma á viku. Til að mynda vinna 42% þeirra meira en 30 tíma á viku meðan hið sama á við um 4,5% staðnema. Það hvort nemar eru í stað- eða fjarnámi tengist ekki aðdráttaraf li kennarastarfsins en hversu ánægðir þeir eru með bæði námskeið í uppeldis- og kennslufræði og kennslufræði greina tengist aðdráttaraf linu, og þættir sem tengjast vettvangsnámi skipta miklu máli. Þetta er í takt við fyrri rannsóknir um mikilvægi þeirrar reynslu sem kennaranemar fá í starfi með námi og í æfingakennslu.

Markmið rannsóknarinnar var að kanna notkun snjalltækja í listgreinum. Í ljósi aukinnar notkunar snjalltækja í skólastarfi og mikilvægis skapandi hugsunar er leitast við að kanna hvernig slík tæki eru notuð í myndmenntakennslu. Jafnframt er markmiðið að kanna notkunarmöguleika tækninnar í myndmennt og tækifæri til sköpunar. Í rannsókninni var notuð eigindleg rannsóknaraðferð og tekin hálfopin viðtöl við fjóra myndmenntakennara og einn margmiðlunarkennara sem starfa í grunnskólum á höfuðborgarsvæðinu. Tilgangurinn var að svara eftirfarandi rannsóknarspurningum: Hver er tilgangurinn með notkun snjalltækja í myndmennt, hvernig nota kennarar tækin í kennslu og hver eru tækifærin til sköpunar? Í þessari grein eru skoðuð viðhorf kennara til tækninnar og snjalltæki sem verkfæri skoðuð. Niðurstöður leiddu í ljós að snjalltæki eru notuð sem tiltekin verkfæri í myndmenntakennslu en þau nýtast nemendum við upplýsingaleit, hugmyndavinnu og efnisleit. Notkun snjalltækja kemur ekki í staðinn fyrir hefðbundnar aðferðir í myndmennt heldur er meginhlutverk þeirra að styðja vinnuferli og verkefni nemenda. Þrátt fyrir takmarkaða notkun snjalltækja í myndmennt og ólík viðhorf kennara til notkunar tækninnar í greininni gefa niðurstöður til kynna að upplýsingatækni og gagnvirkir miðlar geti ef lt skapandi hugsun nemenda. Færni nemenda til sköpunar og þekking þeirra á tækninni gegnir þar stóru hlutverki. Í myndmennt geta skapast tækifæri fyrir kennara til að breyta kennsluháttum sínum með því að nýta snjalltæki á virkan hátt við ný verkefni sem annars væru óframkvæmanleg. Þannig getur tæknin bæði nýst til að breyta nálgun og stutt hefðbundnar aðferðir.

Aim: To study the differences in cardiovascular risk between type 2 diabetic and non-diabetic patients with asymptomatic hyperuricemia and gout using the Framingham Risk Score (FRS) and complex multimodal ultrasonography.

Patients and methods: A total of 201 patients participated, divided into two groups: 1/ patients with asymptomatic hyperuricemia (n = 52), and 2/ patients with gout (n = 149). FRS was determined as well as ultrasound parameters, independent predictors of cardiovascular risk: left atrial size (LA), intima-media thickness (IMT) and common carotid artery resistive index (CCARI).

Results: The patients in the two groups were age-matched and conventional cardiovascular risk factors were equally distributed. In the asymptomatic hyperuricemia group, 12 patients (23.1%) had diabetes. In this group, there was no difference in FRS between diabetic and non-diabetic individuals. However, diabetic patients had larger LA, thicker intima-media and higher CCARI. In the gout group 18 subjects (12%) had diabetes, but the FRS, LA, IMT and CCARI values were similar among diabetic and non-diabetic patients. Furthermore, when gout subjects were subdivided according to the presence of tophi, we found that the subgroup having gouty tophi and diabetes had larger LA (p = 0.014) compared to those with gouty tophi without diabetes.

Conclusion: In diabetic patients with asymptomatic hyperuricemia and gouty tophi, a more complex approach for estimation of cardiovascular risk is needed. Our work suggests that diabetes and tophi might potentiate their action on the cardiovascular system.
