Biological Filtration of Stormwater: Field Operations and Maintenance Experiences
Authors: Mothersill C.L. , Anderson B.C. , Watt W.E. , Marsalek J.
Published: March 2019

Field-scale studies were conducted at the Kingston Stormwater Management Pond to evaluate the impacts of accumulated sediment on the performance of a submerged aerobic biological filter (biofilter) for the remediation of urban Stormwater runoff pollution. Substantial removal of suspended solids (97%) from the influent Stormwater resulted in a significant accumulation of sediment in the biofilter, which interfered with the system's main treatment objective, removing soluble nutrients through bacterial assimilation. The sediment was marginally to significantly polluted by Cd, Cr, Cu, Fe, Pb, Ni and Zn, according to provincial sediment quality guidelines. Removal efficiencies of total organic carbon and orthophosphate phosphorus decreased with time. Good removal efficiency for ammonium nitrogen (64%) was achieved independent of time or sediment accumulation. Backwashing was used to mitigate the effects of sediment accumulation in the filtration unit; however, the backwashing frequency used was not sufficient to maintain optimal biological filtration conditions.

Authors: Lau Y.L. , Marsalek J. , Rochfort Q.
Published: March 2019

Effective treatment of Stormwater by laboratory-scale biofilters has demonstrated that these simple filters may be used to remove dissolved metals and sediment-adsorbed metals found in Stormwater runoff. Laboratory testing indicated that even biofilm just 3 days old provided suspended solids and heavy metals removals in excess of 90%. A filter operated for 9 weeks retained its treatment efficiency and removed more than 90% of total Cu and Zn. Field-scale testing is recommended.
Occurrence and Seasonal Variation of Tributyltin in Marinas on Lake Ontario, Canada
Authors: Yang Fan , Maguire R. James
Published: March 2019

A survey of five marinas and one reference site on Lake Ontario, Canada, was conducted to investigate the occurrence and variation of tributyltin (TBT) levels in water between April and December of 1998. The survey results revealed the presence as well as seasonal trends of TBT in these marinas. The TBT concentrations in water were found to coincide with boating activity. The level of TBT generally rose in summer when the boating activity was high, and the highest level of TBT found was 14 ng Sn/L. On average, 92% of the TBT was in the operationally defined “dissolved phase” in the waters analyzed. The butyltin compounds were also found in surface sediment and paint chips from some non-aluminum hulled pleasure boats, with total concentrations of butyltin species (including dibutyltin and monobutyltin) ranging from 59 to 570 ng Sn/g dry weight, and from 0 to 146 μg Sn/g, respectively. The results clearly indicated that TBT in the marina waters primarily originated from antifouling paint on pleasure boats, even though the use of TBT as an antifouling agent was regulated in 1989.
Comparative Study of the Sediment-Toxicity Index, Benthic Community Metrics and Contaminant Concentrations
Authors: Bombardier Manon , Blaise Christian
Published: March 2019

This paper demonstrates how a new tool for integrating the results of a battery of sediment toxicity tests can be effective in assessing the relative toxic potential of freshwater sediments to aquatic organisms. This tool, called the Sediment-Toxicity (SED-TOX) Index, was applied to laboratory toxicity data derived from two larger projects conducted on freshwater sediments. The SED-TOX Index generates a single value that represents all the results of the different STTs on a common, easily interpreted scale. The SED-TOX results were tentatively correlated with four benthic community metrics (species richness, number of taxa in the orders Ephemeroptera, Plecoptera and Trichoptera, the Shannon-Wiener diversity index, and the ICI-SL, which is a version of the invertebrate community index modified for the St. Lawrence River) and levels of sediment contamination. Although not significant (p = 0.07), SED-TOX scores were most closely related with ICI-SL values; high SED-TOX scores (≥2.0) were always associated with lower ICI-SL scores (<8), which suggests benthos degradation. Agreement was observed between chemistry and SED-TOX results in extreme situations. Indeed, 70% of the sites showing a high hazard potential (≥2.0) in the SED-TOX Index had mean sediment quality guideline (SQG) quotients >5, while 86% of those with a marginal SED-TOX score (0.1 to 0.9) had mean SQG quotients <1. The SED-TOX Index was useful for discriminating sediments based on their hazard potential to a variety of test species and for predicting most (but not all) of the extreme chemistry and benthic community results.
Review of Water Quality Impacts of Winter Operation of Urban Drainage
Authors: Oberts G.L. , Marsalek J. , Viklander M.
Published: March 2019

Urban snowpacks accumulate large quantities of solids and contaminants, which originate from such sources as airborne fallout, vehicular deposition, and applied grit and salt. Both contaminants and solids may be quickly released during the periods of snowmelt and, consequently, melting contaminated snow in urban areas in cold climates has the potential to substantially impact the water quality of receiving water bodies. Although data on the water quality impacts of meltwater are relatively scarce, instances of toxicity of the highly concentrated first flush and deterioration of the receiving water quality by winter discharges of solids and chemicals have been documented. Common rainfall-runoff management techniques do not usually address snowmelt impacts because of the cold weather effects on biological systems and physical processes. Further research on adaptation of conventional Stormwater management techniques to cold climate conditions is needed.
The effect of profitability in income smoothing practice with good corporate governance and dividend of payout ratio as a moderation variable
Authors: Yanti Ni Made Yeni Witaris Asmita , Dwirandra A.A.N.B.
Published: March 2019

One of the factors that influence income smoothing is profitability. Profitability is the ability of a company to earn profits or profits in a certain period and as a measure of the management effectiveness of a company. The variables of good corporate governance and dividend payout ratio are thought to play a role in moderating the effect of profitability on the probability of the occurrence of income smoothing practices. The sample selection method in this study used a purposive sampling method with the criteria of all companies listed on the Stock Exchange which were included in the CGPI ranking from 2012-2016 and companies that distributed dividends from 2012-2016. The sample in this study were 7 companies with 5 years of observation. The variable income smoothing practice is measured using the eckel index. The variable profitability is measured using the ROA (Return On Asset) ratio. Variables of good corporate governance are measured using the CGPI score. Dividend payout ratio variables are measured using the dividend per share formula divided by earnings per share. The analysis technique used is logistical binary regression and Moderated Regression Analysis (MRA).

Published: March 2019

BACKGROUND

Visual analytics (VA) promotes the understanding of data using visual, interactive techniques and using analytic and visual engines. The analytic engine includes machine learning and other automated techniques, whereas common visual outputs include flow maps and spatiotemporal hotspots for studying service gaps and disease distribution. The principal objective of this scoping review is to examine the state of science on VA and the various tools, strategies, and frameworks used in population health and health services research (HSR).

OBJECTIVE

The purpose of this scoping review is to develop an overarching global view of established techniques, frameworks, and methods of VA in population health and HSR. The main objectives are to explore, map, and synthesize the literature related to VA in its application to the two main focus areas of health care.

METHODS

We will use established scoping review methods to meet the study objective. As the use of the term visual analytics is inconsistent, one of the major challenges was operationalizing the concepts for developing the search strategy, based on the three main concepts of population health, HSR, and VA. We included peer reviewed and grey literature sources from 2005 till March 2019 in the search. Independent teams of researchers will screen the titles, abstracts and full text articles, whereas an independent researcher will arbiter conflicts. Data will be abstracted and presented using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist and explanation by two independent researchers.

RESULTS

As of late August 2019, the scoping review is in the full-text screening stage. Data synthesis will follow and the first results are expected to be submitted for publication in December 2019. In this protocol, the methods for undertaking this scoping review are detailed. We present how we operationalized the varied concepts of population health, health services, and VA. The main results of the scoping review will synthesize peer reviewed and grey literature sources on the main methods of VA in the interrelated fields of population health and health services research from January 2005 till March 2019.

CONCLUSIONS

VA is being increasingly used and integrated with emerging technologies to support decision making using large data sets. This scoping review of the VA tools, strategies, and frameworks applied to population health and health services aims to increase awareness of this approach for uptake by decision makers working within and toward developing learning health systems globally.

Wahkohtowin in Action
Authors: Wildcat Matthew
Published: March 2019

From a Canadian legal standpoint, a common concern expressed about Indigenous law is that it is difficult to track down. As Hadley Friedland summarizes, “even people who want to engage more deeply with Indigenous legal traditions struggle to understand how to do so.” In response, Friedland has proposed a case law method that allows Indigenous communities and legal practitioners to access Indigenous law. I believe the case law method can be valuable, but I hope to provide an illustration of the operation of Indigenous law by looking at how the Cree/Metis principle of wahkohtowin was infused through the work of the Maskwacîs Education Schools Commission (MESC).
What happens when the assumptions underlying our commitment to free speech no longer hold?
Authors: Moon Richard
Published: March 2019

A commitment to freedom of expression means that an individual must be free to speak to others and to hear what others may say, without interference from the state. It is said that the answer to bad or erroneous speech is not censorship, but rather more and better speech. Importantly the listener, and not the speaker, is seen as responsible (as an independent agent) for his or her actions, including harmful actions, whether these actions occur because he or she agrees or disagrees with the speaker’s message.

Published: March 2019

Objective: This work aimed to screen the antioxidant activity of marine macroalgae from the Moroccan Atlantic coast (region of El Jadida).

Methods: Evaluation of the antioxidant activity of different collected species, lyophilized and extracted with a solvent mixture chloroform/methanol (2/1; v/v) was conducted according to two techniques, first by thin layer chromatography (tlc) then by spectrophotometry, using a free radical 2,2-diphenyl-1-picrylhydrazyl (dpph). The sampling on a distance of 110 km allowed to harvest 86 algal species (16 brown algae, 47 red algae, 14 green algae and 9 algae being identified).

Results: The analysis by thin layer chromatography reveals an antioxidant activity in nearly half of harvested algal species (52.32 %). This activity varies depending on the concentration of the extract and in function of incubation time in the presence of dpph. The monitoring of the kinetics of degradation of dpph by spectrophotometer in the presence of extracts which were active by tlc allowed to confirm the results and select the most active algal species based on the percentage of remaining dpph in the medium after 120 min of reaction: Fucus spiralis (17.02 %), Cyctoseira ericoides (12.16 %) (Phaeophyceae), and Gracilaria multipartita (36%), Halopitys incurvus (5%) (Rhodophyceae).

Conclusion: The results show that the methodology adopted in this work is reliable and can be used for rapid screening of antioxidant property in plants and the species: Fucus spiralis, Cyctoseira ericoides, Gracilaria multipartita, and Halopitys incurvus can be a promising source of natural compounds endowed with high antioxidant potential.

Jaccard’s similarity coefficient of combined markers segregated the genotypes into two main clusters, 1 with six samples and the others at 0.98 similarity coefficient.

Conclusion: Hence, the molecular analysis could be further used for the identification of important novel gene present in Kaempferia galanga which can be utilized for future crop improvement as well as pharmacological activities.
La administración de la cadena de suministro sustentable y las pequeñas y medianas empresas de economías emergentes: caso México / The Sustainable Supply Chain Management and the Small and medium-sized enterprises of emerging economies: The case of Mexico
Authors: López Santos Yonatan
Published: March 2019

La administración de la cadena de suministro sustentable (sustainable supply chain management o SSCM por sus siglas en inglés) es un tema de investigación que ha cobrado mayor interés en los últimos años; sin embargo, todavía faltan estudios que se enfoquen en la SSCM y en las pequeñas y medianas empresas (pymes) con inversión nacional, principalmente en economías emergentes como la mexicana. Por esta razón, el objetivo de este trabajo fue realizar una revisión literaria para conocer y comprender la situación en la que se encuentran la SSCM y las pymes mexicanas con inversión nacional. El método de investigación para lograr la revisión y alcanzar el objetivo fue por medio de un análisis de contenido. En síntesis, los resultados demuestran que aún existen varios vacíos teóricos a nivel estratégico, táctico y operacional, por lo cual no es posible generalizar modelos conceptuales y matemáticos, ni tampoco es posible generalizar dicha teoría entre economías emergentes y desarrolladas. En consecuencia, se deben concretar más investigaciones centradas en determinados sectores mexicanos en los que también se puedan considerar diversas metodologías para tener una perspectiva más profunda. Aun así, se puede asegurar que la incentivación de la SSCM en las pymes mexicanas puede generar beneficios económicos, sociales y ambientales para los miembros de la cadena de suministro, dependiendo del sector y del caso de estudio.

Authors: Ali Izzadin , Omar Dasimah , Kamaruddin Siti Mazwin
Published: March 2019

The interrelationship between freshwater availability with the growing population and climate change estimates is complex. This article investigates climate change role in freshwater resources availability. This is critical issue as freshwater is vital resource for life, and it is in stake as it is depleted worldwide. Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) was discussed. This paper elucidates the climate model downscaling methods used by scholars for future projections. The applications of modelling could provide a holistic approach based on historical data to predict the effect of climate change on the availability of freshwater. However, the people variability uncertainties dominate assessments of freshwater stress, whilst climate change projections uncertainties are more hypothesized to play a smaller role than people.

Vitex trifolia or locally known as lemuni, is well documented for its medicinal properties including anticancer, antibacterial and wound healing. For years, the leaves and flowers were consumed for anti-aging and general well-being. It is also commonly served as nutraceuticals to post-partum women during their confinement period. Previous study showed that V. trifolia possesses high antioxidant properties that could prevent oxidative stress related diseases such as cancer, atherosclerosis, diabetes and many more. From the literature, V. trifolia leaves are used as poultice for rheumatic pains, sprains, antithelmintics and inflammations. Meanwhile, the fruits are utilised in amenorrhea. The roots, on the other hand, are used for the treatment of cough and fever. The plant is known to possess pharmacologically-active constituents such as the essential oil, halimane-type diterpenes, flavonoids, triterpenes, lignans, iridoids and ecdysteroids. Review papers were consistently published to justify the non-exhaustive biological exploration of this genus. Nevertheless, only 11 per cent of the total Vitex species were phytochemically examined. Apart from being eaten raw or blanched, Vitex is also taken as a food colourant in preparing lemuni rice. The process of making lemuni rice is quite tedious. First, the leaves and flowers are picked and washed. Both parts are then ground with water and sieved to give a bluish extract which is then mixed with rice and boiled to cook. Hence, the Vitex pouch is introduced to provide an easy way to prepare lemuni rice. This packaging is designed to enclose Vitex samples in a pouch that simply can be placed together with rice and boiled to cook. Such instant preparation will hopefully promote the consumption of lemuni rice among busy locals. Future plans include international marketing and production of other Vitex nutritional products.

Published: March 2019

The construction industry should move from conventional construction method and adopt the industrialisation concept, to increase productivity and deliver quality construction end products. Industrialisation is the combination of a large market to divide into fractions the investment in strategies and innovation, in return, of simplifying the production and, therefore, reducing the costs. The introduction of Degree of Industrialisation by Roger-Bruno Richard is critical to the construction industry. The five degrees of industrialisation are prefabrication, mechanisation, automation, robotics and reproduction. Richard’s Degree of Industrialisation is in line with the Malaysian government’s vision to be a developed nation by 2020, to push forward the use of innovative technologies in most industries including the construction industry. The adoption of industrialisation and innovations in the Malaysian construction industry has the potential to solve the current problems in the construction industry. The problems are the inferior quality of products and processes, a poor site working conditions, low construction productivity, high construction cost, relying on foreign workers and lack of skill labours. The adoption of industrialisation and innovations promote sustainability in the construction environment. The objectives of the study are to investigate whether the adoption of industrialisation in the construction environment promotes sustainability and to identify the current level of industrialisation of the Malaysian construction industry. The methodologies of the study are semi-structure interview and observation. The Malaysian construction industry is ready to embrace industrialisation in construction environment in limited areas and industrialisation promotes sustainability in the construction environment.

Published: March 2019

An investigation on the properties of Tenun Pahang fabric performances using alternative yarns was conducted. The studies were made in order to evaluate whether the Tenun Pahang fabric could be produced economically and at the same time maintain the fabric quality. Traditional Tenun Pahang fabric uses silk for both warp and weft. For this project, two alternative yarns were used which were bamboo and modal, which were a little lower in cost compared to silk. These yarns were woven with two variations, one with the yarns as weft only while maintaining the silk warp and the other with both warp and weft using the alternative yarns. Four (4) physical testings and three (3) mechanical testings conducted on the fabric samples. The fabric samples were evaluated including weight, thickness, thread density, crease recovery angle, stiffness and drapability. The results show that modal/silk and bamboo silk fabrics are comparable in terms of stiffness and drapability, hence they have the potential to replace 100% silk Tenun Pahang.

Authors: Barbosa Andreza , Cunha Renata Cristina Oliveira Barrichelo , Martins Verônica
Published: March 2019

Esse artigo sistematiza o estado do conhecimento sobre jornada de trabalho docente evidenciando como a temática vem sendo discutida nas pesquisas. As análises foram organizadas em quatro eixos que abordam as relações da jornada de trabalho com: os salários, a especificidade desse trabalho, o gênero e a legislação. Considerando que a jornada de trabalho é uma das condições que mais influencia a qualidade do trabalho dos professores, é fundamental que os estudos que abordem temas relacionados ao trabalho docente considerem as condições que os professores têm para desenvolver seu trabalho. O caráter inventariante deste artigo pode contribuir com essas discussões.

Authors: Carmo Adriana Fernandes do , Fernandes Karine Gabrielle , Meirelles Marcela Arantes , Carneiro Reginaldo Fernando
Published: March 2019

Neste relato de experiência, discutiremos algumas possibilidades da utilização do jogo Minecraft na formação de professores dos anos iniciais, referente à matemática. Essa temática surgiu da demanda dos participantes de um projeto de pesquisa e extensão ao refletir sobre o ensino e a aprendizagem de ciências e matemática. Desenvolveram-se oficinas que possibilitaram discutir jogos eletrônicos e conteúdos matemáticos que poderiam ser abordados com o Minecraft. Devido a falta de familiaridade com o jogo, ele foi utilizado somente em alguns momentos quando aprendemos sobre sua dinâmica e depois seus conceitos foram explorados de forma lúdica e concreta. Constatamos a importância da visualização em geometria e a possibilidade de desenvolver, por exemplo, estratégias para resolução de problemas.

Authors: Xavier Sousa Junior Paulo de Tarso , Mineiro Martins Hélvia Moreira
Published: March 2019

Este projeto foi realizado com adolescentes do 9o ano do Ensino Fundamental de instituições de ensino da cidade de Teresina-PI com o objetivo de analisar como os adolescentes percebem a escola e quais perspectivas apresentam sobre seu futuro acadêmico. O método utilizado foram técnicas de dinâmicas de grupo, com a finalidade de obter qual a visão desses adolescentes sobre a escola. Conclui-se que os alunos possuem uma visão muito distorcida da escola, uma vez que os profissionais que atuam nela apresentam dificuldades em repassar seu papel. Os adolescentes também ressaltaram a interferência de outros fatores no seu comportamento e desempenho.
A gestão democrática na legislação educacional nacional: avanços, problemas e perspectivas
Authors: Militao Silvio Cesar Nunes
Published: March 2019

Este artigo objetivou analisar as proposições mais significativas relativas à gestão democrática inscritas no conjunto normativo legal educacional nacional editado após o advento da Carta Magna de 1988, a fim de desvelar avanços, problemas e perspectivas para a materialização do referido princípio constitucional nas escolas brasileiras. A pesquisa, de natureza qualitativa, valeu-se de levantamento e análise bibliográfica e documental acerca da temática em questão. Os resultados da pesquisa apontam para uma constante postergação da efetivação da gestão democrática mediante a estratégia de deixar a cargo dos sistemas estaduais e municipais de ensino as formulações concernentes à sua regulação/implantação.

Authors: Lima Hilda Ciriaco , Gama Renata Prentteter
Published: March 2019

O artigo apresenta uma pesquisa qualitativa, do tipo estado da arte, que tem por objetivo descrever e analisar práticas formativas identificadas em 44 pesquisas acadêmicas brasileiras (2001-2016), sobre formação continuada do professor de matemática. A análise indica práticas formativas em quatro contextos (Programas/projetos; Oficinas e cursos de curta duração; Cursos de aperfeiçoamento, especialização ou extensão e Grupos), em que se aproximam da concepção de conhecimento-para-a-prática, no entanto, com tendências de inovações relativas ao planejamento conjunto, diagnóstico de necessidades formativas e análise/reflexão de práticas docentes, apoiadas no trabalho colaborativo.

Authors: Fortunato Ivan
Published: March 2019

O objetivo deste ensaio é analisar as atividades desenvolvidas na disciplina de didática, realizada em 2017, na licenciatura em física. Nessa disciplina, os licenciandos planejaram, executaram e avaliaram seu próprio percurso formativo, com o propósito de refletir sobre a atividade docente. Para ajudar na análise, buscou-se recuperar elementos autobiográficos, úteis no amadurecimento de uma prática pedagógica voltada ao exercício da profissão. Na sequência, a experiência didática foi descrita e analisada à luz da formação de professores.  Ao final desse semestre, os licenciandos puderem evidenciar nuances do cotidiano docente, compreendendo sua complexidade e imprevisibilidade, principalmente ao experimentar a tríplice relação professor-conteúdo-aluno.
Relação família – escola e políticas públicas no Brasil e em Portugal: um estudo da regulamentação da participação parental na gestão escolar
Authors: De Oliveira Rosilane katia , E Nogueira Marlice de Oliveira , De Araújo Regina Magna Bonifácio
Published: March 2019

A partir de uma revisão da literatura, este trabalho discute as legislações portuguesa e brasileira objetivando compreender como os dois países tratam oficialmente o tema da relação entre família e escola, com foco central de análise, a legislação sobre a participação parental na gestão escolar. Os resultados evidenciam que, enquanto em Portugal houve um movimento associativo dos pais, no Brasil, mesmo que se observe uma regulamentação da participação parental na escolarização dos filhos, não se verifica a evidência de algum tipo de movimento associativo de pais e não há clareza sobre os modos como as famílias devem participar da vida escolar da prole.

Authors: Pederiva Vanessa , Silva Jacqueline Silva da
Published: March 2019

Através de uma pesquisa bibliográfica, de caráter qualitativo, este estudo buscou averiguar de que forma a investigação, quando utilizada como estratégia de ensino em sala de aula, pode auxiliar no desenvolvimento do potencial criativo dos alunos. Entende-se que a criatividade é necessária em certo nível para toda pessoa, a fim de identificar e solucionar problemas que surgem no cotidiano. Para tanto, ao fazer uso da prática investigativa, o professor instigará seus alunos a se posicionarem perante situações, construírem seu conhecimento com a interação de todos, proporcionando autonomia e senso crítico em seus alunos e consequentemente, o desenvolvimento da capacidade criativa.

Authors: Freitas Marcos Cezar de , Araujo Nina Rosa Silva de
Published: March 2019

Este artigo analisa fatores que contribuíram para uma bem sucedida transição da educação infantil para o ciclo I do ensino fundamental de uma escola pública, vivenciada por duas crianças surdas. Ambas foram alfabetizadas e aprovadas com resultados satisfatórios. Resultado de estudo etnográfico a análise feita se baseia nas contribuições de Thomas Csordas, Erving Goffman e Annemarie Mol para elucidar como a interação entre professoras e intérpretes da Língua Brasileira de Sinais possibilitou registrar cenas nas quais uma dinâmica inclusiva se estabeleceu. O registro de cenas permitiu coletar interações face a face e uma pedagogia inclusiva foi levada a efeito com estratégias que mostraram a relevância da LIBRAS e a presença singular de um professor surdo no processo.

UZUN SPİNAL KORD LEZYONU OLAN HASTADA BİYOPSİ İLE NÖROMİYELİTİS OPTİKA TANISI: OLGU SUNUMU
Authors: TANOĞLU Ceyda , ÖCAL Ruhsen , KILINÇ TOPRAK Münire
Published: March 2019

Nöromyelitis
Optika Spektrum Hastalıkları (NMOSH) tekrarlayan optik nörit ve longitudinal uzun
segment transvers miyelit atakları ile seyreden, Aquaporin-4 antikor pozitifliği
ile karakterize inflamatuar demiyelinizan bir hastalıktır. Uzun segment longitudinal
transvers miyelit, NMOSH dışında; sistemik otoimmun hastalıklarda, spinal kord tümörlerinde,
spinal vasküler patolojilerde de saptanabilmektedir. NMOSH, genç populasyonda ağır
disabiliteye neden olduğu için erken teşhis ve tedavi çok önemlidir. Bu sunumda,
akut parapleji ve idrar inkontinansı şikayeti ile polikliniğimize başvuran yirmi
üç yaşındaki kadın hasta tartışılmıştır. Spinal Manyetik Rezonans Görüntüleme’de
C7-T7 arasında kord içinde kontrast tutan longitudinal uzun
ödemli lezyon saptandı. Astrositom olarak raporlanması nedeniyle lezyondan biyopsi
yapıldı ve tümör düşünülmedi. NMOSH tanısı sonradan doğrulanan Aquaporin-4 pozitifliği
ile kesinleşti. Uzun segment spinal lezyonlar, NMOSH’da nadir olmasa da lezyonun
ödematöz ve beklenenden uzun olması nedeniyle bu olguyu sunmak istedik.
ANALYSIS OF TRAFFIC ACCIDENT VICTIMS ADMITTED TO INTENSIVE CARE UNIT IN THE PROVINCE OF KIRSEHIR FROM MAY, 01, 2016 TO MAY, 01, 2018: A RETROSPECTIVE STUDY
Authors: CANTÜRK Mehmet
Published: March 2019

Objective: To present the epidemiologic data of traffic accident victims hospitalized at an intensive care unit.Material and Methods: Medical files of patients admitted to hospital as a traffic accident victim and hospitalized at intensive care unit from May 01, 2016 to May 01, 2018 were retrospectively analyzed. Age, gender, admission time, type of trauma, mechanical ventilation, and surgery were recorded.Results: Of the 99300 patients hospitalized due to traffic accidents, 86 patients needed intensive care unit care. Mean age of the patients was 41.80 ± 23.04 years. Fifty-five patients were male, and 31 patients were female. Sixty-two patients were under 60 years of age. Intensive care unit hospitalization was most frequent (39 patients, 45.3%) between 08:00-15:59 hours. Multiple trauma patients constituted 38.4% of the cases. Mean length of stay at the intensive care unit was   2.94 ± 4.01. Of the 86 patients; 51 were transferred to the wards, 14 transferred to a reference hospital, one discharged and 20 patients died. Conclusion: Although patients admitted to intensive care unit due to traffic accidents constitute a small percentage, they still have a high mortality rate. Increasing measures of control at times when traffic accidents are common can prevent deaths in productive age groups.
