Published: March 2020

Introdução: A prevalência de lesão por pressão (LP) varia com o ambiente clínico e as características do paciente, assim, pacientes com traumatismo raquimedular (TRM) configuram-se entre aqueles com maior predisposição diante do tempo de internação, apresentando movimentos e sensibilidade prejudicados. Objetivo: Conhecer e analisar a prevalência de LP em pacientes vítimas de TRM internados em um hospital de referência. Método: Estudo transversal, retrospectivo. A amostra compõe-se de prontuários de pacientes com TRM que apresentaram LP durante a internação em um hospital de referência no estado do Pará, Brasil, durante o período de 2013 a 2016. Resultados: Analisaram-se 565 prontuários de pacientes com trauma raquimedular, com a prevalência de lesão por pressão em de 8% dos pacientes com TRM. A média de idade foi de 37 anos, com 80% composta por homens, com tempo médio de internação de 66,68 dias. A maioria apresentou como etiologia da lesão medular os acidentes por arma de fogo e queda, com 32 e 30% respectivamente. A lesão medular foi predominante na região torácica (50%), onde 64% tiveram a paraplegia como sequela e 86% apresentaram LP em região sacral. Conclusão: Foi possível identificar a prevalência de lesão por pressão em pacientes com traumatismo raquimedular e conhecer seu comportamento. Desse modo, a disponibilização dos dados ajudou a demostrar a ocorrência de LP como complicação em pacientes com TRM durante a internação, podendo servir como base para a alocação de recursos e medidas preventivas, como também estudos posteriores sobre a temática.

Viral advertising has become a trending topic nowadays. This study aims to examine the effect of advertising appeals on viral advertising, brand awareness, and purchase intentions with the hedonic personality playing as a moderating role. The use of hedonic personality itself to predict viral intentions, brand awareness, and purchase intentions have not been widely discussed by other researchers. This study can be classified as explanatory research with purposive sampling and partial least square as sampling techniques and data analysis. This study was designed to focus on individuals who can be classified as social media active users with a minimum age of 18 years old. The result shows that advertising appeals (humor and informative) have a positive and significant impact on viral intention and attitude toward advertisement. Thus, the higher viral intention and the positive attitude toward advertisement will increase the possibility of purchase and the level of brand awareness. While hedonic personality was significantly proved moderates the relationship between viral intentions and brand awareness in this study. The nature of respondents in this study who mainly are at high level of hedonic personality make the moderation role of hedonic personality has no significant impact on the relationship of viral intentions on purchase intentions.

Plant pigments as pH indicators in cooking
Authors: Motturi Heli , Slawuta Sari , Salkunen Sirpa , Rajala Petra
Published: March 2020

Controlling acidity comes up often during cooking. Food’s acidity can be discussed in connection to using vinegar, marinade or baking soda in cooking. One seldom considers that acidity affects the food’s colour and thus its appeal. Colour is especially significant for ready-made foods. Berry jam or juice that is too pale or too dark does not look fresh or appealing. Many of the foods that lose their colour easily contain nature’s own pH indicators, anthocyanins.

The workshop detailed in this article explores discolouration of anthocyanins with the help of different methods. Anthocyanins offer many points of discussion for chemistry classes, because in addition to their indicator properties, anthocyanins are also flavonoids and food additives. The work instructions are mainly aimed at grades 7 to 9. The chemistry part involving anthocyanins is suitable for upper secondary school as well, since it is challenging. The article details a demonstration that motivates towards inquiry-based work and two alternative work instructions.

Two finnish girls and mathematics: Similar achievement level, same core curriculum, different competences
Authors: Viitala Hanna
Published: March 2020

Mathematical thinking and problem solving are essential parts of learning mathematics described in the Finnish National Core Curriculum for Basic Education. Evaluations on both have been done at national and international level. However, in a request for deeper understanding of pupils’ mathematical thinking we need to move beyond paper tests. This paper is a first look into the mathematical thinking of two Finnish girls, Emma and Nora, in their final year of Finnish comprehensive school. After solving a real-life situated problem in a classroom, the girls talk about mathematics and problem solving in an interview. The focus of the analysis is on the learning objectives, core content and final-assessment criteria related to thinking skills and methods in the Finnish curriculum. Also some results on metacognition and affect will be reported. The results suggest that while both pupils have similar achievement level in mathematics, their competences are different: Emma is more competent in problem solving and Nora is more self-confident and self-guided in learning mathematics and can more easily recognize mathematics outside school.

Clarifying chemistry concepts through language analysis
Authors: Mammino Liliana
Published: March 2020

Chemistry concepts often pose considerable challenges to students at all levels of instruction, from secondary school to all the university courses. The search for options to facilitate clear and complete understanding is a major commitment of chemistry education research. Teaching and learning depend on communication effectiveness. Language is the most fundamental communication tool. Its communication effectiveness in education depends on the degree of rigour and clarity with which sentences are built and assembled to form a text, and on the learners’ ability to identify all the information conveyed by the text. Language analysis proves a powerful tool to facilitate full identification of the information in a text. It is also optimal to stimulate further reflection on the various features of a concept through the analysis of frequently occurring errors or of errors in learners’ work. After an introduction on the reasons making language analysis a powerful clarification tool, this paper considers illustrative examples from different tertiary-level chemistry courses, to highlight the practical implementation aspects and emphasise the integration between the analysis of chemistry concepts and the language-type analysis of the sentences expressing them. Because of its nature, the approach relies on in-class interactions. It has proved beneficial and rich of potentials for further explorations. The design of options for close collaboration between chemistry teachers and language teachers is expected to become the key for more generalised application.

Kemian aineenopettajakoulutusyksikön tavoitteena on kouluttaa osaavia tutkivia ja yhteisöllisiä opettajia tulevaisuuden kouluihin. Tuleville kemian opettajille pyritään läpi koko koulutuksen kehittämään hyvät TVT-taidot sekä taitoa käyttää digitaalisia opetusvälineitä ja ohjelmia osaavasti ja ennakkoluulottomasti omassa opetuksessaan kemian opetussuunnitelman perusteiden tavoitteiden mukaisesti. Teknologis-pedagogisen sisältötiedon (TPCK) sekä tieto- ja viestintätekniikan mahdollisuuksien ja haasteiden esille tuominen ovat tärkeä osa tulevien kemian opettajien koulutusta. Tämä artikkeli esittelee Kemian opettajankoulutusyksikössä laaditun TVT-strategian ja pohtii sen soveltuvuutta kemian aineenopettajakoulutukseen. Lisäksi esitellään esimerkin avulla, miten strategian käytännön toteutuksen vaikutusta kemian aineenopettajaopiskelijoiden tietoihin ja taitoihin on seurattu. Sen mukaan suunnitelmallinen TVT-strategiaan pohjautuva opetus näyttäisi edistävän monipuolisesti kemian opettajaksi opiskelevien TVT-taitoja. Erityisesti opiskelijat kokivat oppineensa simulaatiosovelluksia kemian käsitteiden ja ilmiöiden opettamiseen sekä relevantteja ohjelmia materiaalien ja ideoiden jakamiseen. Kurssien jälkeen opiskelijat arvioivat TVT-taitonsa erityisen vahvoiksi sähköisten oppimisalustojen, yhteisöllisen tekstinkäsittelyn, ja kemian opetusmateriaalien etsimisen suhteen. Tässä esiteltyä TVT-strategiaa ollaan tutkimuspohjaisesti kehittämässä ja suuntaamassa kemian oppimisen ja opetuksen kannalta tärkeisiin tulevaisuuden taitoihin sekä osaamisalueisiin.

Berdasarkan hasil survey yang didapat oleh penulis, maka penulis dapat menyimpulkan bahwa menjadi Guru Profesional yang diidamkan oleh siswa ada sebanyak 15 point penting yang harus dimiliki oleh Seorang Guru. Peran Guru ketika disekolah sebagai orang tua bagi siswa. Dimana Guru harus berperan sebagai sosok panotan siswanya agar suasan belajar menjadi sesuatu yang menyenangkan dan sesuai dengan apa yang diharapkan. Siapa yang tidak mau menjadi guru yang diidamkan oleh siswa. Sepertinya semua guru akan mengharapkan hal ini. Akan tetapi tahukah kita bahwa semakin minta diidamkan siswa, maka akan semakin jauh kita dari kriteria guru yang layak diidamkani siswa? jika menjadi guru yang diidakan oleh siswa merupakan tujuan utama kita, maka sebagai guru tidak ada yang namanya profesionalisme lagi, yang ada hanyalah menuruti apa yang siswa mau dan yang diinginkan oleh siswa. Menjadi guru yang diidamkan oleh siswa juga bukan berarti menuruti semua yang siswa mau atau inginkan. Karena jika guru menuruti semua keinginan siswa bisa jadi malah membuat keluar dari tujuan dan kegiatan proses belajar mengajar.

By mid-March 2020, the COVID-19 pandemic spread to over 100 countries and all 50 states in the US. Government efforts to minimize the spread of disease emphasized behavioral interventions, including raising awareness of the disease and encouraging protective behaviors such as social distancing and hand washing, and seeking medical attention if experiencing symptoms. However, it is unclear to what extent individuals are aware of the risks associated with the disease, how they are altering their behavior, factors which could influence the spread of the virus to vulnerable populations. We characterized risk perception and engagement in preventative measures in 1591 United States based individuals over the first week of the pandemic (March 11th-16th 2020) and examined the extent to which protective behaviors are predicted by individuals’ perception of risk. Over 5 days, subjects demonstrated growing awareness of the risk posed by the virus, and largely reported engaging in protective behaviors with increasing frequency. However, they underestimated their personal risk of infection relative to the average person in the country. We found that engagement in social distancing and handwashing was most strongly predicted by the perceived likelihood of personally being infected, rather than likelihood of transmission or severity of potential transmitted infections. However, substantial variability emerged among individuals, and using data-driven methods we found a subgroup of subjects who are largely disengaged, unaware, and not practicing protective behaviors. Our results have implications for our understanding of how risk perception and protective behaviors can facilitate early interventions during large-scale pandemics.

Orbitopatía distifroidea después de yodoterapia en enfermedad de graves
Authors: Medina Orjuela Adriana , Rojas William , Hernández María Clemencia
Published: March 2020

Antecedentes: la liberación de antígenos de la glándula tiroides después del tratamiento con yodo radioactivo, con un aumento de autoanticuerpos tiroideos, tienen una reacción cruzada entre células de la tiroides y fibroblastos de la órbita, lo cual lleva a una infiltración por células T activadas, agravando la orbitopatía preexistente por enfermedad de Graves. Tanto el hiper como el hipotiroidismo pueden exacerbar las manifestaciones oculares. Después de la yodoterapia hay un 3 a 5% de riesgo de enfermedad ocular detectable en pacientes que no tenían orbitopatía. En el 16 % con oftalmopatía detectable y 56 % con severa antes de la yodoterapia, pueden empeorar los hallazgos oculares. Se ha encontrado que los cambios oculares posyodoterapia son transitorios y dependen de factores de riesgo como tabaquismo, niveles de T3 antes del tratamiento y orbitopatía preexistente. Métodos: se estudiaron 58 pacientes durante dos años con diagnóstico de enfermedad de Graves que fueron sometidos a yodoterapia y se les realizó exoftalmometría y cuantificación de los síntomas de orbitopatía antes, un mes y seis meses después de la terapia.Resultados: Al mes del tratamiento, el 13,79% mejoró la exoftalmometría, el 62,07 % permaneció igual y el 24,14% empeoró, y a los 6 meses el 29,31% mejoró, el 50% permaneció igual y el 20,69% empeoró. Esto evidencia mejoría de la exoftalmometría a los 6 meses de tratamiento, con unap= 0,000. Los síntomas oculares como ojo rojo, ardor ocular, prurito, epífora, sensación de cuerpo extraño y diplopia, se evaluaron por separado antes del tratamiento y al mes y seis meses después de efectuado. Los hallazgos fueron estadísticamente significativos. Los pacientes que recibieron prednisolona, tuvieron una tendencia a mejorar los síntomas oculares, p= 0,053.Conclusión: Los pacientes que reciben tratamiento con yodo radioactivo para la enfermedad de Graves presentan mejoría o estabilidad significativa de la orbitopatía o una disminución de la exoftalmometría en los que no tienen orbitopatía previa a la yodoterapia. La prednisolona tiende a tener una influencia favorable en la evolución de la orbitopatía.

La investigación tuvo como objetivo general describir los factores medioambientales y de autocuidado presentes en enfermos con peritonitis en tratamiento con diálisis peritoneal continua ambulatoria, en el periodo comprendido entre el 23 de abril de 2004 y el 1 de octubre de 2004, en la unidad renal de Fresenius Medical Care del hospital de San José de Bogotá. Los objetivos específicos fueron describir las características medioambientales, identificar los factores de autocuidado presentes y determinar los microorganismos causales. Hubo 17 pacientes con peritonitis, de los cuales uno falleció, tres no aceptaron participar en el estudio, dos fueron trasladados a hemodiálisis y uno cambió a Laboratorios Baxter. La muestra final fue de diez (10) enfermos. En cuanto al germen causal, tres presentaron Staphylococcus epidermidis, Streptococcus viridians y Staphylococcus aureus. Dos resultaron con cultivos negativos. La muestra corresponde a 70% sexo masculino y 30% femenino, con promedio de 51 años (desviación estándar 9,57 años), 30% trabajadores independientes, 20% pensionados, 20% en ocupaciones de hogar, 10% en zapatería y 20% sin trabajo, 10% profesional, analfabeta 10%, cursaron primaria 50% y bachillerato 30%. El 50% pertenecen al estrato 2,30% al 3, 10% al estrato 1 y estrato 4, respectivamente. El tiempo promedio en el programa fue de 34 meses (con desviación estándar 34,47 meses), con un mínimo de 12 y un máximo de 120 meses. En su totalidad realizan ellos mismos el recambio peritoneal. Los que presentaron peritonitis se relacionaron con baja escolaridad, factor que limitaría el aprendizaje del autocuidado. La educación verbal dada a los familiares y al paciente en el programa DPCA, no asegura el cuidado adecuado. La situación socioeconómica es una de las limitaciones del autocuidado, pues imposibilita la adquisición de elementos imprescindibles como las toallas desechables. Varios continúan desarrollando acciones inapropiadas que los ponen en riesgo de llegar a presentar infección, que se debe por lo regular a que siente mejoría y desea continuar con el estilo de vida que llevaba antes de enfermar.
