Published: December 2014

A point-of-care workflow checklist in the form of an iOS (iPhone Operating System) app for use by stroke providers was introduced with the objective of standardizing acute stroke evaluation and documentation at 2 affiliated academic medical centers. Providers used the app in unselected, consecutive patients undergoing acute stroke evaluation in an emergency department or hospital setting between August 2012 and January 2013 and August 2013 and February 2014. Satisfaction surveys were prospectively collected pre- and postintervention from residents, staff neurologists, and clinical data specialists. Residents (20 preintervention and 16 postintervention), staff neurologists (6 pre and 5 post), and clinical data specialists (4 pre and 4 post) participated in this study. All 16 (100%) residents had increased satisfaction with their ability to perform an acute stroke evaluation postintervention but only 9 (56%) of 16 felt the app was more help than hindrance. Historical controls aligned with preintervention results. Staff neurologists conveyed increased satisfaction with resident presentations and decision making when compared to preintervention surveys. Stroke clinical data specialists estimated a 50% decrease in data abstraction when the app data were used in the clinical note. Concomitant effect on door-to-needle (DTN) time at 1 site, although not a primary study measure, was also evaluated. At that 1 center, the mean DTN time decreased by 16 minutes when compared to the corresponding months from the year prior. The point-of-care acute stroke workflow checklist app may assist trainees in presenting findings in a standardized manner and reduce data abstraction time. The app may help reduce DTN time, but this requires further study.
Cabs, community, and control: Mobile communication among Chicago’s taxi drivers
Authors: Williams Maggie Griffith
Published: December 2014

Today’s mobile technology and mobile professions mean that people are nearly always either in, or connected to someone who is in motion. And yet, communities persist in the face of this constant motion. This is a qualitative study of a mobile labor group—taxi drivers in Chicago. Similar to Wallis’s (2011) conclusions, I found that access to and use of a mobile phone does not automatically imbue taxi drivers with power and autonomy from forces that seem to be working against them. However, access to mobile phones does help to shake up the hierarchy of control in the taxi industry. This study has also identified another type of community where the theory of polymedia (Madianou & Miller, 2012) applies, that is, labor communities, and has shown that while choice of technology may offer some sense of power, access to mobile communication technology does not necessarily result in significant changes in power structures within and surrounding a community.
Communicating behind the scenes: A primer on radio frequency identification (RFID)
Authors: Frith Jordan
Published: December 2014

Mobile media researchers have increasingly focused on smartphones as locative media. However, our field has not devoted as much attention to another mobile technology used to track far more people and things than smartphones: radio frequency identification (RFID) tags. RFID tags are used to track products and people, and they are an increasingly important part of the infrastructure of the Internet of Things. This article argues that mobile media scholars have much to contribute to scholarly analyses of RFID. I make that argument by first giving background on RFID as a mobile technology. I then identify and discuss four areas of research related to RFID tags—Big Data, surveillance, space and place, and nonhuman agency—that are particularly relevant to mobile media scholars.
Towards an understanding of intention to use mobile videos: Impression management, perceived facilitation, and social norms
Authors: Lin Trisha T. C. , Younbo Jung , Sim Clarice
Published: December 2014

Due to prevalent use of phablets and 3G/4G cellular networks, watching mobile videos has become increasingly popular worldwide. This study identifies multilevel psychosocial factors predicting individual intention to use mobile audiovisual services. The national telephone survey obtained a random sample of 503 respondents. The findings show variables of the theory of planned behavior (TPB; i.e., attitude, subjective norm, and perceived behavioral control) and social norms are key predictors for mobile video consumption. In the research model, impression management is significantly associated with attitude, subjective norm, and individual social norms while perceived government and operator facilitation are associated with collective social norms. The hierarchical multiple regression analysis reveals that the extended TPB model accounts for 62% variance of intention to use mobile videos.
Anomalous Origin of Single Coronary Artery From Pulmonary Artery
Authors: Shetty Ravi Shankar , Thareen Jameel Khan , Ramaiah Anil Kumar Hpalya , Narayan Ravi , Das Jayantha Kumar , Chandrashekariah Mahesh M.
Published: December 2014

Anomalous origin of a single coronary artery from the pulmonary artery is a rare and potentially fatal congenital heart malformation. Although the actual incidence is not known, it is rarer than anomalous left coronary artery from pulmonary artery. In the absence of other important congenital cardiac anomalies, patients with anomalous origin of a single coronary artery from the pulmonary artery typically experience myocardial ischemia in association with the physiological decrease in the pulmonary vascular resistance that typically occurs over the first few months of life. To our knowledge, there have been only three reported cases of successful surgical correction. We describe a very unusual case in which the diagnosis was made intraoperatively during surgery to close a ventricular septal defect.
Intrapleural Fibrinolysis During Pediatric Extracorporeal Life Support
Authors: Witt Cordelie E. , Mesher Andrew L. , Hermsen Joshua L. , Brogan Thomas V. , McMullan David Michael
Published: December 2014

Pediatric patients who require extracorporeal life support (ECLS) for refractory cardiorespiratory failure are at increased risk for intrapleural hemorrhage due to the effects of systemic anticoagulation and frequent occurrence of pneumothorax. Surgical evacuation is standard therapy for retained hemothorax to prevent secondary empyema, pulmonary compression, and development of fibrothorax. However, surgical interventions during ECLS are hazardous and place patients at increased risk for surgical site bleeding. Intrapleural fibrinolysis with tissue plasminogen activator may be used to facilitate nonsurgical evacuation of retained hemothorax. We present two pediatric patients who were safely and successfully managed with intrapleural fibrinolysis of retained hemothorax during ECLS.

Published: December 2014

Background:

In developing countries, more children with complex cardiac defects now receive treatment for their condition. For successful long-term outcomes, children also need skilled care at home after discharge. The Parent Education Discharge Instruction (PEDI) program was developed to educate nurses on the importance of discharge teaching and to provide them with a structured process for conducting parent teaching for home care of children after cardiac surgery. The aim of this pilot study was to generate preliminary data on the feasibility and acceptability of the nurse-led structured discharge program on an Indian pediatric cardiac surgery unit.

Methods:

A pre-/post-design was used. Questionnaires were used to evaluate role acceptability, nurse and parent knowledge of discharge content, and utility of training materials with 40 nurses and 20 parents. Retrospective audits of 50 patient medical records (25 pre and 25 post) were performed to evaluate discharge teaching documentation.

Results:

Nurses’ discharge knowledge increased from a mean of 81% to 96% ( P = .001) after participation in the training. Nurses and parents reported high levels of satisfaction with the education materials (3.75-4 on a 4.00-point scale). Evidence of discharge teaching documentation in patient medical records improved from 48% (12 of 25 medical records) to 96% (24 of 25 medical records) six months after the implementation of the PEDI program.

Conclusion:

The structured nurse-led parent discharge teaching program demonstrated feasibility, acceptability, utility, and sustainability in the cardiac unit. Future studies are needed to examine nurse, parent, child, and organizational outcomes related to this expanded nursing role in resource-constrained environments.
An Unusual Cause of Persisting Hyperlactatemia in a Neonate Undergoing Open Heart Surgery
Authors: Simalti Ashish Kumar , Joshi Raja , Aggarwal Neeraj , Agarwal Mridul , Joshi Reena K.
Published: December 2014

Being a reflection of the degree of global tissue anoxia, serum lactate levels therefore can be used as a marker of organ damage and eventual outcome. A statistically significant association was observed between serum lactate levels and subsequent mortality and morbidity in critically ill adults, children, and neonates. In cardiac critical care, hyperlactatemia is usually multifactorial in origin, resulting from a combination of etiologies. Many centers are using serial lactate levels in conjugation with other parameters of cellular oxygen delivery, consumption, or extraction to monitor prognosis after pediatric cardiac surgery. A single initial lactate level has a lesser predictive value for morbidity and mortality after pediatric cardiac surgery than its failure to fall within 48 hours of surgery. In case of persistently high lactate levels with no other evidence of cellular hypoperfusion, other possibilities must be considered. There has been an established association of lactic acidosis with thiamine deficiency, but this has not yet been reported in newborns undergoing congenital cardiac surgery. We present one such rare case.
Disease-Specific Outcome Analysis of Palliation With the Modified Blalock-Taussig Shunt

Published: December 2014

Background:

Albeit being a simple surgical procedure, adverse outcomes with the modified Blalock-Taussig shunt (MBTS) are commonly reported in generalizing terms, independent of the underlying heart disorder.

Methods:

From August 1995 to December 2013, a total of 150 children underwent an MBTS for tetralogy of Fallot (TOF; n = 44, 29%), pulmonary atresia with ventricular septal defect (PA/VSD; n = 28, 19%), pulmonary atresia with intact ventricular septum (PA/IVS; n = 17, 11%), transposition of the great arteries with ventricular septal defect (TGA/VSD) with pulmonary stenosis (PS; n = 12, 8%), Ebstein malformation (n = 2, 1%), and complex univentricular anomalies (n = 47, 31%). Outcome analysis focused on operative mortality and survival until shunt takedown, adjusted to the underlying disease.

Results:

In-hospital mortality was 8.7% (n = 13), and interstage mortality was 5.1% (n = 7), resulting in 86.1% survival to the next surgery. Hospital mortality was 14% in PA/VSD, 13% in univentricular heart, and 18% in PA/IVS, while no mortality was observed in TOF, TGA/VSD/PS, and Ebstein disease. A shunt-related complication was observed in 18% (n = 27) of the children, including acute thrombosis (n = 7, 5%), shunt stenosis (n = 3, 2%), overshunting (n = 7, 5%), and pulmonary artery stenosis (n = 10, 7%). Multivariate analysis of shunt-dependent time survival identified a shunt complication occurring in a univentricular circulation (hazard ratio [HR] 4.10, 95% confidence interval [CI] = 1.05-17.43, P = .01) and increased shunt size-to-weight ratio (HR 2.72, 95% CI = 0.80-9.18, P = .04) as risk factors. Shunt thrombosis was also a negative outcome predictor in PA/VSD, when requiring associated unifocalization ( P = .05).

Conclusion:

This study shows that the outcome of palliation with the MBTS is importantly affected by the occurrence of a shunt-related complication, whose circulatory effect is even more dismal in single ventricle hearts. Since an increased shunt size-to-weight ratio additionally compromises the shunt-dependent survival, it emphasizes that the choice of the shunt with regard to size as well as surgical approach remains critical.
Ultrasonographic Surveillance of Abdominal Aortic Endovascular Aneurysm Stent Graft Repair in a Dedicated Vascular Laboratory
Authors: Sorrentino Kimberly , Shah Parth S. , Bendick Phillip
Published: December 2014

Surveillance following abdominal aortic endovascular aneurysm repair (EVAR) is imperative to confirm graft patency, analyze residual sac size (RSS), and evaluate for complications. This retrospective study evaluated ultrasonographic (US) surveillance after EVAR compared to computed tomography (CT). US was done by 1 of 11 experienced registered technologists. US was ordered for surveillance more frequently than CT, with a ratio of 4:1. Compared to CT, US endoleak evaluations were 74% sensitive and 76% specific with a 63% positive predictive value and 84% negative predictive value. However, 11 CT scans were likely false negatives, and 1 CT was a false positive. For true positives that stated endoleak type, there was a 93% agreement between the type on US and CT. US had a 75% accuracy for RSS (95% CI, −1.02 to 1.16). These data support the use of US along with clinical symptoms as a first-line surveillance program after EVAR and are widely applicable to the majority of vascular laboratories that employ multiple registered vascular technologists. The adaptation of increased US surveillance would decrease the number of CT scans, thereby significantly reducing cost and radiation/contrast exposure to patients.
A Novel Echocardiographic Marker (PDAM) Incorporating the Diameter of the Patent Foramen Ovale to Assess Hemodynamically Significant Patent Ductus Arteriosus
Authors: Guthrie Joy D.
Published: December 2014

Persistent hemodynamically significant patent ductus arteriosus (PDA) in preterm infants may lead to significant morbidity and increased mortality. This report proposes a new composite marker to predict a hemodynamically significant PDA, termed the PDA marker (PDAM) score, which incorporates the diameter of the patent foramen ovale (PFO) in addition to the ratio of the diameter of the left atrium to the diameter of the root of the aorta (LA/Ao) and ratio of the size of the patent ductus arteriosus to the left pulmonary artery (PDA/LPA) diameter. PDA was suspected in 191 infants between 2009 and 2013. Analysis of the data indicated that there was no significant difference between the accuracy of the PDA diameter and the PDAM score as markers of either a hemodynamically significant PDA or a very hemodynamically significant PDA that needed ligation. These data did show that the PDAM score provided slightly higher sensitivity (93.3%) and specificity (75.6%) than the PDA diameter to identify a PDA that needed ligation at the specified cutoff level of PDAM = 5.1. Consequently, clinicians may be more confident using the PDAM score, rather than the PDA diameter alone, when selecting PDA cases for surgical intervention.

Cytokine crowdsourcing: multicellular production of TH17-associated cytokines
Authors: Busman-Sahay Kathleen O , Walrath Travis , Huber Samuel , O’Connor William
Published: December 2014

In the 2 decades since its discovery, IL-17A has become appreciated for mounting robust, protective responses against bacterial and fungal pathogens. When improperly regulated, however, IL-17A can play a profoundly pathogenic role in perpetuating inflammation and has been linked to a wide variety of debilitating diseases. IL-17A is often present in a composite milieu that includes cytokines produced by TH17 cells (i.e., IL-17F, IL-21, IL-22, and IL-26) or associated with other T cell lineages (e.g., IFN-γ). These combinatorial effects add mechanistic complexity and more importantly, contribute differentially to disease outcome. Whereas TH17 cells are among the best-understood cell types that secrete IL-17A, they are frequently neither the earliest nor dominant producers. Indeed, non-TH17 cell sources of IL-17A can dramatically alter the course and severity of inflammatory episodes. The dissection of the temporal regulation of TH17-associated cytokines and the resulting net signaling outcomes will be critical toward understanding the increasingly intricate role of IL-17A and TH17-associated cytokines in disease, informing our therapeutic decisions. Herein, we discuss important non-TH17 cell sources of IL-17A and other TH17-associated cytokines relevant to inflammatory events in mucosal tissues.

Purpose

To compare age-dependent changes in health status among childhood cancer survivors and a sibling cohort.

Methods

Adult survivors of childhood cancer and siblings, all participants of the Childhood Cancer Survivor Study, completed three surveys assessing health status. At each of three time points, participants were classified as having poor outcomes in general health, mental health, function, or daily activities if they indicated moderate to extreme impairment. Generalized linear mixed models were used to compare survivors with siblings for each outcome as a function of age and to identify host- and treatment-related factors associated with age-dependent worsening health status.

Results

Adverse health status outcomes were more frequent among survivors than siblings, with evidence of a steeper trajectory of age-dependent change among female survivors with impairment in at least one health status domain (P = .01). In adjusted models, survivors were more likely than siblings to report poor general health (prevalence ratio [PR], 2.37; 95% CI, 2.09 to 2.68), adverse mental health (PR, 1.66; 95% CI, 1.52 to 1.80), functional impairment (PR, 4.53; 95% CI, 3.91 to 5.24), activity limitations (PR, 2.38; 95% CI, 2.12 to 2.67), and an adverse health status outcome in any domain (PR, 2.10; 95% CI, 1.97 to 2.23). Cancer treatment and health behaviors influence the magnitude of differences by age groups. Chronic conditions were associated with adverse health status outcomes across organ systems.

Conclusion

The prevalence of poor health status is higher among survivors than siblings, increases rapidly with age, particularly among female participants, and is related to an increasing burden of chronic health conditions.
Central Sirt1 Regulates Body Weight and Energy Expenditure Along With the POMC-Derived Peptide α-MSH and the Processing Enzyme CPE Production in Diet-Induced Obese Male Rats
Authors: Cyr Nicole E. , Steger Jennifer S. , Toorie Anika M. , Yang Jonathan Z. , Stuart Ronald , Nillni Eduardo A.
Published: December 2014

In the periphery, the nutrient-sensing enzyme Sirtuin 1 (silent mating type information regulation 2 homolog 1 [Sirt1]) reduces body weight in diet-induced obese (DIO) rodents. However, the role of hypothalamic Sirt1 in body weight and energy balance regulation is debated. The first studies to reveal that central Sirt1 regulates body weight came from experiments in our laboratory using Sprague-Dawley rats. Central inhibition of Sirt1 decreased body weight and food intake as a result of a forkhead box protein O1 (FoxO1)-mediated increase in the anorexigenic proopiomelanocortin (POMC) and decrease in the orexigenic Agouti-related peptide in the hypothalamic arcuate nucleus. Here, we demonstrate that central inhibition of Sirt1 in DIO decreased body weight and increased energy expenditure at higher levels as compared with the lean counterpart. Brain Sirt1 inhibition in DIO increased acetylated FoxO1, which in turn increased phosphorylated FoxO1 via improved insulin/phosphorylated AKT signaling. Elevated acetylated FoxO1 and phosphorylated FoxO1 increased POMC along with the α-melanocyte-stimulating hormone (α-MSH) maturation enzyme carboxypeptidase E, which resulted in more of the bioactive POMC product α-MSH released into the paraventricular nucleus. Increased in α-MSH led to augmented TRH levels and circulating T3 levels (triiodothyronine, thyroid hormone). These results indicate that inhibiting hypothalamic Sirt1 in DIO enhances the activity of the hypothalamic-pituitary-thyroid axis, which stimulates energy expenditure. Because we show that blocking central Sirt1 causes physiological changes that promote a negative energy balance in an obese individual, our results support brain Sirt1 as a significant target for weight loss therapeutics.
International Economic Relations’ Risk Criterion
Authors: Басовская  , Basovskaya Elena , Басовский  , Basovskiy Leonid
Published: December 2014

A criterion for an assessment of international economic relations’ risks has been offered. This criterion is based on proposed approach to assessment of risks for world economic dynamics and economic dynamics of different countries and territories. The economic dynamics risk is estimated by comparison of economic growth rates’ average size and a risk measure — a mean square deviation of growth rates. Definition for a line of market of international economic relations’ prospects is offered, similar to the capital market line in the financial assets’ profitability model (CAPM). On the basis of IMF data for 2004-2013 the economic dynamics risks for Europe and CIS countries have been estimated. It has been established that in Europe only economies of Switzerland, Poland, Albania and Malta have the risks below the world economy ones. From among the largest economies the smallest risks have economies of Great Britain, Germany and France. The greatest risks have economies of Italy and Spain. In the CIS only Belarus, Kazakhstan, Tajikistan, Turkmenistan and Uzbekistan have the risks below the world economy ones. From among the CIS countries the Ukraine has the worst risk criteria.

Os impactes dos incêndios florestais nos bosques esclerófilos costeiros mediterrâneos do Chile. O caso da região de Valparaíso
Authors: Pérez Víctor Quintanilla
Published: December 2014

Os bosques mediterrâneos do Chile estão muito alterados, sobretudo devido aos incêndios florestais. Uma das situações mais grave corresponde à das bacias costeiras que rodeiam as cidades de Valparaíso e Viña del Mar, cuja expansão avançou até às colinas circundantes, nas quais se destaca a presença de pequenos bosques esclerófilos que conservam una importante biodiversidade e, sobretudo, a palmeira endémica Jubaea chilensis (Moll) Baillon, a qual está permanentemente ameaçada pela alta combustibilidade da paisagem vegetal em que vive. Outros impactes antrópicos, como seja o avanço do habitat urbano, as obras de infraestruturação, o uso do fogo e a construção de estradas contribuem para a vulnerabilidade destes ecossistemas.

O homem e a construção da cidade no Renascimento. O prazer e o dever
Authors: Soares Nair Castro
Published: December 2014

O prazer e o dever, noções essenciais à condição do homem e sua realização como ser individual e social, foram objecto de reflexão desde os primórdios da Civilização do Ocidental. Mas foi sobretudo na época helenística que se afirmaram sistemas filosóficos que, na sua complementaridade, procuraram dar resposta à problemática do humano.O Humanismo renascentista assistiu, no seu eclectismo filosófico, ao reacender do questionamento sobre a felicidade, em termos que equacionavam o livre arbítrio, a superioridade relativa do intelecto e da vontade, a acção humana e a graça divina. A grande originalidade desta época, por inspiração aristotélica, é a união que se firma entre a acção, o trabalho, o dever e o prazer; entre a utilitas e a uoluptas, não em termos de antinomia, mas de complementaridade, com reflexos na literatura, na tratadística doutrinária e parenética, na poesia e na arte.A um estado de alma, por essência subjectivo e vivencial, se agrega uma motivação ontológica de serviço à colectividade, inerente à dignidade da pessoa humana, à sua eudaimonia, e indispensável ao prestígio, à gloria e magnificentia humanistas, que traduzem – sem se perder o sentido da cidade de Deus – o splendor e a magnificentia na construção da cidade dos homens.http://dx.doi.org/10.14195/2183-1718_66_14

Este estudo apresenta o biógrafo jesuíta António Franco (1662-1732), autor da obra Imagem da Virtude. Embora confesse os seus propósitos pedagógicos e apologéticos, o Padre António Franco revela exigências históricas  e críticas  no momento em que a hagiografia (género literário em que poderíamos incluir as suas vidas edificantes) começa a afirmar-se como ciência crítica, mas não prescinde da sua dimensão apologética. O estudo propõe ainda uma leitura desta obra no contexto da pedagogia espiritual da Companhia que valoriza não só uma concepção edificante da história e da historiografia, como o princípio espiritual da imitatio sanctorum.http://dx.doi.org/10.14195/2183-1718_66_15

A crise social na Atenas de Sólon e o estabelecimento da justiça baseada no governo da lei
Authors: Carvalho Sofia Gil , Jácome Neto Félix
Published: December 2014

A primeira parte deste artigo remete para a caraterização da crise social que Sólon buscou remediar quando arconte em 594/3, onde são feitas considerações teóricas sobre o modo como Aristóteles e Plutarco, as principais fontes literárias, explicam os acontecimentos deste período. A partir do diálogo com as fontes e com a bibliografia especializada são explanadas algumas hipóteses de trabalho sobre o que poderia estar implicado na crise a que o legislador ateniense teve que fazer frente. Na segunda parte, a atenção voltar-se-á para o sentido geral da atuação política de Sólon através dos seus próprios poemas, especialmente o fr. 36W, onde Sólon mostra indícios de uma politização das relações económicas entre as classes sociais, na medida em que traz, de certa maneira, a resolução dos conflitos entre os indivíduos e os grupos sociais para o âmbito da cidade-estado ateniense, promovendo a noção de lei escrita que deve ser cumprida e assegurada pelo coletivo como o remédio para escapar aos interesses particulares ou de classe que têm levado a stasis, ou seja, ao conflito social. O artigo, em sua conclusão, destaca que o estudo destes acontecimentos é relevante para a reflexão moderna sobre a relação entre força, violência e direito.http://dx.doi.org/10.14195/2183-1718_66_4
La retórica del poder y las relaciones entre los estados en las tragedias griegas de suplicantes
Authors: Quijada Sagredo Milagros
Published: December 2014

Desde su origen en Grecia y hasta nuestros días, la retórica ha articulado el discurso sobre el poder y las relaciones entre los estados como un instrumento a la hora de crear consensos o de justificar políticas imperialistas. En este artículo nos proponemos analizar algunos de los términos en los que este discurso se ofreció, así como los dilemas a los que dio lugar en las tragedias griegas de suplicantes.http://dx.doi.org/10.14195/2183-1718_66_6
Alimentação e guerra nas Histórias de Heródoto
Authors: Soares Carmen
Published: December 2014

Neste estudo procede‑se a uma análise dos principais passos das Históriasem que se abordam as relações entre alimentação e guerra. Numa primeira parte considera‑se a importância das causas económicas da guerra, relativas ao abastecimento de bens alimentares das populações. Na segunda, o papel que a alimentação desempenha em pleno cenário de guerra. Conclui‑se que Heródoto, não obstante o relevo que dá na sua narrativa à influência que o carácter dos protagonistas da guerra (reis e generais) tem no desenho dos quadros bélicos, revela uma clara consciência do enquadramento económico básico que ao longo da história da humanidade sempre subjaz (de forma mais ou menos preponderante) aos conflitos armados.http://dx.doi.org/10.14195/2183-1718_66_7
Relatos da Peste em Virgílio, Geórgicas III, e Lucrécio, De rerum natura VI
Authors: Trevizam Matheus
Published: December 2014

Dois relatos sobre catastróficas epidemias destacam-se na literatura romana. São eles o relato da Peste de Atenas ao fim do sexto livro do De rerum natura (DRN) de Lucrécio e o da Peste Nórica ao fim do terceiro livro das Geórgicas de Virgílio. Nosso intento, neste artigo, será apresentar de forma comparativa o aspecto da sintomatologia nesses relatos dos dois autores, considerando o frequente diálogo de Virgílio com Lucrécio na passagem citada.http://dx.doi.org/10.14195/2183-1718_66_9
Enhancing the surface properties of linen by
non-thermal atmospheric air-plasma treatment
Authors: Erzsébet Szabó Orsolya , Csiszár Emília , Tóth András
Published: December 2014

In this research, a diffuse coplanar surface barrier discharge (DCSBD) type plasma reactor was used for the surface modification of raw linen fabric. Changes in physical properties and chemical composition of the fiber surface as well as color of the fabric were measured as
a function of time of the atmospheric air plasma treatment. Furthermore, ageing of the effects created on the fiber surface by plasma treatment was also characterized in
a period of 0-14 days elapsed after the plasma treatment. Significant differences were found between the properties of the raw and plasma treated linen fabrics, including increase of wettability, wickability, surface energy and O/C ratio, and decrease of water contact angle and deterioration of the waxy outer layer of the fibers.
Most of the parameters depended on the time of plasma treatment (0–180 s). O/C ratio increased steadily with the increase of duration of the plasma treatment, which was explained by destruction of the waxy surface layer, creation of polar groups and exposure of cellulosic components. Most of the properties tested were found
to be stable during two weeks of storage after the plasma treatment, indicating that the surface ‘topography’ created by plasma remained almost unaltered and the recovery
of the etched waxy coverage of the fiber did not occur.
Mathematics Textbook as an Object of Research/Matematički udžbenik kao predmet istraživanja
Authors: Glasnović Gracin Dubravka
Published: December 2014

AbstractA mathematics textbook can be described as an officially authorized and pedagogically designed mathematics book written to provide mathematical knowledge to students. This description suggests the authority of the textbook - because it has been authorized by an administrative source and because it deals with authorized knowledge. This paper provides an overview of research on mathematics textbooks. The emphasis is on questions concerning the extent to which and how textbooks are used in mathematics education in Croatia and in the world. Research results show that mathematics textbooks are widely used in mathematics education worldwide. This finding points to the need for research on the content and structure of textbooks. Such studies are combined with the associated results on how textbooks are used in the classroom and which methods teachers apply in using textbooks in mathematics education. The results of the empirical studies show that teachers use textbooks for lesson preparation and pupils use mathematics textbooks for exercises to a great extent. These results imply that such an important role of textbooks in mathematics education deserves additional attention, with the goal of understanding and improving mathematics education. Key words: mathematics education; overview; research on textbook  --- SažetakMatematički udžbenik može se opisati kao službeno autorizirana i pedagoški osmišljena matematička knjiga napisana s ciljem da učenicima ponudi matematičke sadržaje.

Published: December 2014

Background: The discovery of leptin has led to the elucidation of a robust physiologic system that not only maintains fat stores but is also an integral part of the host defense mechanism. However, leptin concentrations in the saliva of patients with chronic periodontitis (CP) has not been explored despite the potential role of salivary biomarkers in determining the presence, risk, and progression of periodontal disease.

Methods: Eighty‐four participants (44 with generalized severe CP and 40 without periodontitis) were enrolled. For each patient, the values of periodontal parameters were recorded, such as plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment loss (AL), and percentage of sites with bleeding on probing (BOP) and clinical AL ≥5 mm. Saliva and serum samples were collected to estimate the leptin concentrations using enzyme‐linked immunosorbent assay kits. Statistical analysis was performed using software.

Results: Participants with CP demonstrated significantly higher BOP, PI, GI, and percentage of sites with clinical AL >5 mm (P <0.05). Leptin was detectable in all the clinical samples. Salivary leptin concentrations in patients with CP were significantly lower than in healthy volunteers (6,200.61 ± 2,322.11 versus 8,799.60 ± 901.70 pg/mL), whereas serum leptin concentrations were significantly higher in patients with CP than in healthy volunteers (11,600.00 ± 1,705.01 versus 7,616.62 ± 1,169.83 pg/mL). In addition, the results reflected a significant negative correlation of salivary leptin and a positive correlation of serum leptin with PD (P <0.05).

Conclusion: The results suggest that leptin concentrations in saliva and serum are significantly altered in CP and relate closely to current disease activity; however, further studies are needed to confirm the findings.
Calibration of a 2D laser scanner system and rotating platform using a point-plane constraint
Authors: Kurnianggoro Laksono , Hoang Van-Dung , Jo Kang-Hyun
Published: December 2014

The purpose of this study was to produce a low cost 3D scanner system using a
rotating 2D laser scanner. There are two key parameters of this system, the
rotation axis and the rotation radius. These two parameters were extracted
through a calibration procedure. The calibration requires a planar
checkerboard calibration pattern. Several poses were scanned to obtain the
observation data. The rotation axis and the rotation radius were extracted by
solving a linear equation constructed from a point-plane constraint, where
all points lie on a plane and have a zero dot product to the surface normal
to the plane. This method was tested on a simulation environment by
generating synthetic data of the scanned calibration pattern. A comprehensive
analysis was carried out to evaluate the performance of the proposed method.
From the simulation results, it was demonstrated that this method achieved
highly accurate results with an orientation error of 0.018 degree and a
radius error of 0.2 cm.
Product Market Competition and Audit Fees
Authors: Wang Yuequan , Chui Andy C. W.
Published: December 2014

Existing theories posit two contradictory predictions on the relation between product market competition and audit fees. On the one hand, product market competition can mitigate agency problems between shareholders and managers and increase the accuracy of financial reporting, thus decreasing auditors' assessments of audit risk. Hence, auditors tend to charge lower fees to firms in a more competitive industry. On the other hand, product market competition can increase auditors' assessments of business risk. Therefore, audit fees are expected to increase with industry competitiveness. This study empirically tests the relation between product market competition and audit fees and finds that auditors charge more to firms in a more competitive industry.

Are Juries More Likely to Second-Guess Auditors under Imprecise Accounting Standards?
Authors: Kadous Kathryn , Mercer Molly
Published: December 2014

U.S. auditors are concerned that less precise accounting standards will cause more second-guessing of their judgments and thus greater legal liability. We report the results of an experiment that tests the validity of this concern. We manipulate the aggressiveness of the client's reporting decision and the precision of the accounting guidance related to the reporting decision. When the client's reporting is conservative, we observe more second-guessing of auditor judgments under the imprecise standard than the precise standard. However, when the auditor allows aggressive client reporting, we observe less tendency toward second-guessing under the imprecise standard. Indeed, rather than being overly harsh, juries appear to be overly lenient when auditors allow aggressive accounting under an imprecise standard. Our results suggest a need for tools to help jurors evaluate auditor judgments under imprecise standards.
