Reading digital- versus print-easy texts: a study with university students who prefer digital sources

The transition from on-paper to on-screen reading seems to make it necessary to raise some considerations, as a greater attentional efort has been claimed for print texts than digital ones. Not surprisingly, most university students prefer this digital medium. This research aims to examine reading times by contextualizing this phenomenon into two processes: namely, word recognition and reading comprehension task on paper and on screen. Thus, two diferent tasks­counterbalanced into digital and print mediums­were carried out per each participant with a preference for a digital medium: a reading comprehension task (RCT) and a lexical decision task (LDT) after reading a specifc story. Participants were slower reading print texts and no statistically signifcant diferences were found in RCT accuracy. This result suggests that the task required more cognitive resources under the print medium for those with a worse comprehension performance in reading, and a more conservative pattern in digital RCT for those with a better performance.

Perception of the use and understanding of nutrition labels among different socioeconomic groups in Mexico: a qualitative study / Percepción del uso y comprensión del etiquetado de alimentos en diferentes grupos socioeconómicos de México: un estudio cualitativo

Abstract: Objectiv: To explore the perception of the use and comprehension of the nutrition labeling (GDA, NFT, NS) and claims in packaged foods among different socio economic-status (SES). Materials and methods: This was a qualitative study, 12 focus groups were performed in four cities of Mexico. Participants were recruited outside the supermarkets, which were selected according to SES using Basic Geostatistical Areas. The focus groups had a total of 78 participants. Results: Participants perceived several barriers to the use and understanding of the GDA; like technicalities of the terms used, and the format (small font size and percentages). Claims are mistrusted in general. Participants from the high SES believed that the claims are just a marketing strategy. Conclusion: This study shows the consumers' difficulties to understand the current nutrition labeling system regardless SES. These data might call attention in order to implement a simpler nutrition labeling system that is understood regardless of SES.

Luxación de la articulación temporomandibular: apropósito de un caso y su diagnóstico diferencial / Luxation of the temporomandibular joint: about a case report and its differential diagnosis

Resumen La luxación temporomandibular es infrecuente, pero genera gran repercusión en el esqueleto facial. En ocasiones el cuadro clínico inicial es inespecífico y puede confundirse con otras patologías si no se tiene un adecuado conocimiento del tema, o se realiza una anamnesis incorrecta. Este artículo presenta el caso de una paciente que consultó al servicio de urgencias por disartria y desviación de la comisura labial hacia la izquierda, asociado a dolor severo y parestesia en hemicara derecha. No obstante, al ingreso la paciente refirió síntomas ambiguos, que para el médico evaluador sugirieron una causa neurológica. Durante la observación se solicitó valoración por servicio de cirugía plástica, se logró orientación de la anamnesis y examen físico, obteniendo una impresión diagnóstica de luxación de articulación temporomandibular derecha, confirmada por imagenología, y por ende un tratamiento oportuno con reducción e inmovilización en el servicio de urgencias. MÉD.UIS.2019;32(3):49-54

Abstract The temporomandibular joint dislocation is uncommon, but it causes a great repercussion on the facial skeleton. Occasionally, the initial symptoms can be unspecific and confuse with other pathologies if there are not an adequate knowledge of the topic and the anamnesis is incorrect. This article presents a clinical case of a patient with dysarthria and left deviation of the labial commissure, associated with severe pain and paresthesia in the right side of the face. Nevertheless, the patient initially referred ambiguous symptoms, suggesting a neurological cause. During observation in the emergency room, plastic surgery service valorated the patient, with subsequent orientation of the anamnesis and physical examination, achieving a satisfactory management of the acute dislocation.

[Comparison of sleep disorders in shift and non-shift workers employed in a printing factory in Tehran 2010]

According to the previous studies, 25 percent of the total workforce is faced with the shift working. Sleep disorders are the most common health complaint of the shift workers. This study was designed to examine the sleep status of workers in a printing factory. We aimed to investigate the association between prevalence of sleep disorders with shift working and other probable factors. This cross-sectional study was conducted among workers of a printing factory in Tehran, 2010. Required information was gathered through a questionnaire consisting of three parts: Demographic data, ESS questionnaire [Epworth Sleepiness Scale] and SMII questionnaire [Sleep Med Insomnia Index]. Collected data from 385 questionnaires were analyzed using SPSS software version 16. P values <0. 05 were considered significant statistically. According to the results of the analysis, shift working, drug consumption and smoking were significantly associated with the prevalence of sleep disorders [especially with prevalence of insomnia]. Logistic regression analysis was also performed for insomnia. The Odds Ratio for shift working and drug consumption were 2.3 and 3.2, respectively. Based on this study, shift working could be considered as an important risk factor of sleep disorders. However, further studies are needed to confirm this theory and to plan for reducing such disorders among shift workers

Lenticular card: A new method for denture identification.

Aim: The need for denture marking is important for forensic and social reasons in case patients need to be identified individually. Majority of the surface marking and inclusion techniques are expensive, time consuming, and do not permit the incorporation of large amounts of information. In this article, the method to include a lenticular identification card stood out from the currently available denture marking methods in various ways. The lenticular card stores the patient's information has two or more images that can be viewed by changing the angle of view. Materials and Methods: The maxillary denture was processed according to the manufacturer's instructions. The lenticular identification card was incorporated in the external posterior buccal surface of the maxillary denture using salt and pepper technique. For testing of durability, denture with the identifier was placed in water for up to 4 months. Conclusion: The proposed method is simple, cheap, and can store a large amount of information, thus allowing quick identification of the denture wearer. The labels showed no sign of fading or deterioration.

Efectos de los desinfectantes en hidrocoloides irreversibles / Effects of disinfectants on irreversible hydrocolloid

Los hidrocoloides irreversibles son los materiales más utilizados para obtener impresiones dentales. Después de realizada la impresión con el material y técnica adecuadas, el paso que sigue antes del vaciado es la desinfección. Las impresiones no deben representar vehículos de transmisión de microorganismo que puedan generar contaminación cruzada entre pacientes, personal dental y de laboratorio. La naturaleza del desinfectante, el tiempo que actúa sobre la impresión, La técnica de desinfección utilizada y la concentración de los desinfectantes influyen sobre la estabilidad dimensional de las impresiones. Una adecuada interacción entre los agentes químicos desinfectantes y los materiales de impresión trae como resultados modelos de trabajo libres de contaminación, sin sacrificar la exactitud y las dimensiones lineales de las impresiones dentales. Los objetivos del presente trabajo son describir los cambios dimensionales según el desinfectante y el procedimiento utilizado para la desinfección de impresiones con hidrocoloides irreversibles y diferenciar cual es la técnica que posee los mejores resultados en la desinfección de impresiones con hidrocoloides irreversibles. El propósito es proporcionar al odontólogo general información sobre la concentración y tiempo óptimos que deben actuar los desinfectantes sobre los hidrocoloides irreversibles de manera a evitar las infecciones cruzadas y mantener la estabilidad dimensional. Las conclusiones fueron que el procedimiento de inmersión y de aspiración realizadas en forma correcta no producen efectos significativos sobre la estabilidad dimensional, que las inmersiones hasta 30 minutos no alteran la precisión clínica de las impresiones con hidrocoloides irreversibles y que el procedimiento de inmersión es la mejor técnica para desinfección por su mayor contacto con el material .

A bibliographical study on the Gapjinjache Naeuiwonjabon of Sikmulboncho / 의사학

"Sikmulboncho" that is quoted several times to "Donguibogam(Medical Thesaurus of Korea)" published several times in 3 countries(Korea, China & Japan) as important data of botany study. Gapjinjache "Sikmulboncho", one of the bronze metal type, that exist our country was publicated in early Seonjo(1552-1608) era. Actually there are 3 items(Korea university collection, Asami library collection, Oksan seowon collection) of Gapjinjache Naeuiwonjabon one of the wooden type seen become publication after 1607 year. Bronze metal type composes the major part for Gapjinjabon, but wood type was also mixed much. Wooden type composes the major part for Naeuiwonjabon, while bronze type was little mixed. Bronze metal type disappears by wear class gradually to during 40 years and instead of this, used wood type was used. Foundation and base of this publication have formed in itself Eulhaejache Naeeuiwonjabon that start "Donguibogam" in process that do this way. Therefore, Naeeuiwon do not publish various medical books like a Naeeuiwonjabon suddenly in early 17th century. I can speak that is caused in experience and potential power that already publish this Gapjinjabon medical book ago by medical history.

Occupational hearing impairment among noise-exposed workers in printing facilities

The present field study aimed at determining the prevalence and factors affecting hearing impairment among printing workers. A cross sectional survey of 144 eligible printing facilities workers was done. Exposure categories to noise either [low vs. high risk] were assigned to studied workers according to the work nature. An interview questionnaire, workers audiometric assessment and workplace noise levels have been measured. The overall prevalence of hearing impairment was 31.3%, and among those [high risk exposure] 44.1% of workers had hearing impairment, while only 8.5% of those exposed to low level of noise had hearing impairment. Multivariate analysis revealed that occupational exposure to noise, age and smoking were the strongest predictors [ORs: 7.3, 5.4, 2.8 respectively] of hearing impairment among studied workers. The observed hearing loss was located mainly at 4000 Hz and findings indicate that high risk workers are occupationally exposed to high levels of noise, and present high rates of noise-induced hearing loss [NIHL]. There is a need for interventions to reduce the risk for the development of NIHL among exposed workers

Carbamoylethylated cassia gum as thickener in printing linen fabrics

Galactomannan gum isolated from the Cassia seeds was subjected to carbamoylethylation which involved the reaction of the gum with acrylamide along with sodium hydroxide as a catalyst. Four carbamoylethylated Cassia gum samples having different nitrogen content [2.78 to 4.28%] were prepared via changing the amount of the etherifying agent used [25 to 100g acrylamide/ 100g dry gum]. Modification of Cassia galactomannan gum via carbamoylethylation converts the gum into a water soluble derivative and increased its stability to storing. The results related with the rheological characterization of the carbamoylethylated Cassia gum derivatives showed that it exhibited non-Newtonian pseudoplastic behaviour irrespective of the degree of carbamoylethylation. Increasing the extent of carbamoylethylation was accompanied by an enhancement in the apparent viscosity. Storing of the pastes for three days caused a decrease in their apparent viscosties, which may be due to partial hydrolysis of the modified gum molecules. It can be concluded that carbamoylethylated Cassia gum derivatives could be used successfully as suitable thickening agents in reactive printing of linen fabrics

Improving polyester fabrics working properties using alkali printing

Two different weights of 100% polyester fabrics were printed with meypro gum thickening agent containing sodium hydroxide with different concentrations. Different steaming time and temperature were also applied to determine the optimum conditions for this alkali printing of polyester fabrics. Polyester fabrics including first prints were overprinted with a second print paste containing disperse dye. Some working properties of the printed fabrics like air permeability and water repellency were improved. Colour strength of the printed areas: was also increased. Using of ammonium compound surfactants increases weight loss and accelerates the treatment

Evaluation of hematological and genotoxic effects of chronic occupational exposure to lead in printing house workers

Adult lead poisoning commonly occurs from exposure to lead used in workplace. Lead exposure can cause a wide spectrum of adverse health effects. Its genotoxic effects are still debatable. To measure the adverse effects of lead exposure in printing house on some hematological parameters [red blood cells count, hemoglobin, and hematocrit levels] of workers, and to investigate its genotoxic effects on their leukocytes. The study was carried out on 40 workers exposed to lead in their work at Menoufiya University printing house, and ten control subjects selected from an area free from lead exposure and matched for age and smoking habit. An ex-post-facto study design was used. An interview questionnaire was used to assess biosocial characteristics, occupational history, and work related symptoms. Blood lead, red blood cells [RBCs], hemoglobin [Hb], and hematocrit levels [Hct] were evaluated. DNA fragmentation assay was used for detection of DNA fragmentation in leukocytes. Lead exposed workers has significantly higher mean blood lead than that controls [p < 0.001], 26.4 +/- 7.1 micro g/dL and 8.7 +/- 4.1 micro g/dL, respectively. Exposed workers has significantly lower mean RBCs [4.7 +/- 0.4], Hct [38.2 +/- 4.2] and Hb [13.9 +/- 0.7], compared to controls 5.2 +/- 0.5, 41.3 +/- 4.1, and 14.6 +/- 1.5, respectively. Statistically significantly higher frequency of symptoms of metallic taste, weight loss, fatigue, lack of memory, visual disturbance, and joint pain were reported by exposed workers, compared to controls. Statistically significant increased mean of optical density of DNA fragments at 200, 400 and 600 base pair of leukocytes of lead exposed workers were also shown, compared to controls. Statistically significant negative correlations were revealed between blood lead, duration of work and RBCs, Hct, and Hb. Statistically significant positive correlations were also revealed between blood lead, duration of work and total mean of optical density of DNA fragments. Occupational lead exposure, with increased blood lead level, is associated with decreased RBCs, Hct, and Hb and increased DNA fragmentation in leukocytes of printing workers. It is also associated with increased frequency of many related reported symptoms. Occupational health sendees are essential to eliminate the hazardous effect of lead exposure
