ELT Teacher Trainees Attitudes Towards Environmental Education And Their Tendency To Use It In The Language Classroom
Authors: Gursoy Esim , Saglam Gulderen T.
Published: March 2016

With the change of focus in language teaching from grammar-based approaches to more communicative approaches, contextual language learning gained importance and found body in the English Language classroom. Global issues constitute one of the most popular contexts for purposeful language learning and meaningful language use. Increasing number of ELT (English Language Teaching) course books involve global issues in their content. Within the scope of socially responsible teaching (SRT) it is believed that it is the teachers responsibility to help their learners develop awareness on these issues. From this perspective current research aims to shed some light into ELT teacher education process by investigating teacher trainees attitudes and tendencies towards environmental education and their inclusion in the ELT lessons. Data for the research is collected from 224 third year ELT teacher trainees via a questionnaire prepared by the researchers. The reliability of the questionnaire was tested by using Cronbachs alpha and found to be .821 . As a result, it was found that third year ELT teacher trainees have mildly positive attitudes on environmental education. In addition, there were no statistically significant differences among the participants sex and their membership at environmental organizations on their attitudes towards environmental education and their tendency to use them in language education. The result of this study is significant for numerous stakeholders, including teacher education programs, Ministry of Education, state leaders and surrounding communities and families of English language learners in relation with the efforts to integrate environmental education to the ELT curriculum.
Primary School Teachers Perceptions Regarding ICT Usage And Equipment In Kuwait
Authors: Alharbi Ghazwa
Published: March 2016

Education institutions around the world have seen rapid advances in ICT (Information Communication Technology) within the classroom since the mid 90s. Kuwait has realized the need for a high quality education system, and has seen huge increases in government funding for schools over the last 10 years. However, Kuwaits spending on technology and ICT has attracted little research regarding the impact it has had on students and teachers. For this reason, this study aimed to discover how useful ICT is within classes in Kuwait. The research used qualitative research to focus on 14 teachers from three different primary schools in Kuwait. The study focused on the amount of ICT that is used within Kuwaiti schools and the quality of ICT training provided for teachers. The study found that teachers lacked sufficient training in ICT usage as a teaching aid. Findings also revealed that programs provided by the primary schools in Kuwait were too basic and that further investment is required
Primary Teacher Education In Malaysia
Authors: Ching Chin Phoi , Yee Chin Peng
Published: March 2016

In Malaysia the training of primary school teachers is solely carried out by teacher training institutes which offer the Bachelor of Teaching with Honors (Primary education) program and was first launched in 2007. This program prepares primary school teachers specializing in various subjects or major and is carried out in 27 teacher training institutes. The main aim of this program is to produce quality primary school teachers in terms of knowledge, skills and professional competencies in their respective subjects and in line with the National Philosophy of Education. After a span of five years, has this Bachelor of Teaching program achieve its learning outcomes outlined? Thus this study intends to evaluate this primary teacher education program by focusing on the achievement of learning outcomes (LO) of this four years program. The sample involved in this study is a group of 106 final year student teachers who have completed their 8th semester of study. A questionnaire was administered to check the extent of the learning outcomes being achieved. This questionnaire was developed based on the eight main learning outcomes of this Bachelor of Teaching program. The question items were written individually by referring to the sub outcomes of each main LO. Thus this studys main objectives are to find out to what extent the overall LO was achieved and also to determine the importance of each LO. The results would serve as guidelines for the teaching staff to further improve their teaching practices and guidance given to students in the future.

The organizations researched are business schools and the data collected came from chairpersons of accounting departments of AACSB member business schools. We use a reworded Narver and Slater (1990) market orientation scale and the Jaworski and Kohlis (1993) overall performance scale for use in the current research. 101 chairs of accounting departments whose schools are members of AACSB responded to the survey. The manuscript details the data collection and analysis processes, the statistical findings, along with implications and a call for additional subject matter research.
Prospective ELT Teachers Attitudes Toward The English Language In An EFL Context
Authors: Gursoy Esim
Published: March 2016

Attitudes toward a foreign language and the motivation to learn a language have been of interest to many educators and researchers. However, the majority of research has been conducted with language learners. There is a lack of literature concerning the attitudes of teachers and teacher trainees toward the language they are or will be teaching. Thus, the current study aims to investigate English Language Teaching (ELT) teacher trainees attitudes toward the English language and their self-reported difficulties when using their foreign language skills in daily and academic language. Two hundred teacher trainees participated in the study. The questionnaire, which was developed via an extensive literature review and adaptations of Karahans (2007) and Al Zahranis (2008) studies, was found reliable (Conbachs alpha, .876). The study showed that trainees have mildly positive attitudes toward the English language, with females being more positive than males. The findings also suggest that trainees have stronger instrumental motivation than integrative motivation. Moreover, the results indicate that trainees do not differ significantly in terms of their difficulties in using daily language skills. However, there are some statistically significant differences in academic language, such as vocabulary and monologue speech. In addition, there are statistically significant differences between males and females in speaking and reading comprehension for daily language, as well as reading comprehension for academic language.
Students Motivations For Voluntary Remedial Learning In High School
Authors: Pelletier Daniel , Green-Demers Isabelle , Lafleur Karine
Published: March 2016

Most high schools offer remedial learning sessions to their students; however, very little is known about the perception of these activities, especially with regards to the students motivations. In order to gain insights into both topics, an exploratory study was conducted within a sample of 1388 high school students in the Province of Quebec (Canada). Participants were selected on the basis of their voluntary participation or non-participation in remedial learning sessions held at school. School motivation was measured with a questionnaire based on Deci and Ryans SDT (Self Determination Theory); perceptions were gathered and measured with open-ended and multiple choice items. Quantitative results indicated that participants of remedial learning sessions were more strongly motivated towards school. No significant relationships were found between attendance and grades, with similar proportions of high, average and below average participating and non-participating students; however, among participants, girls outnumbered boys by 2:1. Two main categories emerged from qualitative analyses: remedial learning can be seen as: a) an instrumental support linked to the subject matter; or b) a relational support which fosters better learning.

Will Accountants Become Purveyors Of All Information?
Authors: Doney Lloyd D.
Published: March 2016

When computers first appeared in organizations, accountants had an opportunity to enlarge their information-providing responsibilities by embracing the new technology and the people who made it work. They elected not to pursue this opportunity and, perhaps unwittingly, launched not only a new group of information professionals, but also a new and sometimes competitive information function in organizations. Now some accountants are suggesting that the profession expand its boundaries to include all information. A second opportunity for accountants to become the purveyors of all information may exist due to a different set of circumstances that are more favorable to acting on the opportunity. Unlike the earlier situation, accountants would not have to deal with management responsibility for the technology and its related information professionals. Further, the continuing move toward integrated systems lends itself to a more global approach. Ultimately, whether accountants become the purveyors of all information will depend upon whether accountants move to meet the new demands for information in organizations. Accountants who are effective in advising managers in matters that combine both financial and non-financial, as well as internal and external information, should be successful in expanding their role as information providers.
Accounting And Visual Basic: Whats The Connection?
Authors: Simkin Mark G. , Bagranoff Nancy A.
Published: March 2016

It is not enough today for accountants simply to know how to use word processing and spreadsheet software. In the knowledge age, accounting professionals must use infor-mation technology to the fullest. The ability to create, process, understand, and distri-bute information often determines work productivity, ratings on job performance evaluations, and even ultimate career successes. Accounting graduates with superior information technology (IT) skills are highly recruited, valued, and rewardedthese are the employees who are best able to perform the computer tasks required by their professional responsibilities. This paper reviews some reasons why todays accountants must be familiar with programming concepts in general, and Visual Basic (VB) in par-ticular. It also reviews those VB programming tools that are especially useful to accounting applications.
Converting Paradoxs QBE Set Queries Into Access 2000 SQL
Authors: Dadashzadeh Mohammad
Published: March 2016

One of the most important promises of the move to an SQL-based accounting software package has been that it frees the accountant from the necessity of resorting to a programmer when retrieving information from the organization's database in response to unanticipated managerial needs. That promise is founded, in part, on the availability of a very high-level, visual relational query language interface known as Query By Example (QBE). Unfortunately, the implementation of QBE in Microsoft Access 2000 fails to support users in formulating complex queries involving set comparison that tend to arise in on-line analytical processing (OLAP) situations. And, while Paradoxs implementation of QBE makes the formulation of such queries quite intuitive, its built-in SQL translation feature fails to provide a clue on how to convert such queries into SQL. This paper presents a systematic approach based on formulating complex set queries in Paradoxs richer QBE notation and translating them into SQL queries that can be handled by Access 2000.
What Determines Incumbent Auditors Information Systems Design And Implementation Consulting Fees?
Authors: Lee Ho Young
Published: March 2016

This study examines determinants of demand for incumbent auditors information systems design and implementation consulting services. While there was no evidence on how the services may affect auditor independence, opponents of allowing the service argue that auditors who provide the financial information systems consulting services may lower audit quality, reducing investor confidence in markets. The results indicate that while R&D expenditures, auditors industry specialization, and auditor tenure are positively associated with demand for the information systems consulting, there is no evidence that accounting discretion and audit committee effectiveness are associated with demand for the information systems consulting.
Problem Solving Method Based On E-Learning System For Engineering Education
Authors: Khazaal Hasan F.
Published: March 2016

Encouraging engineering students to handle advanced technology with multimedia, as well as motivate them to have the skills of solving the problem, are the missions of the teacher in preparing students for a modern professional career. This research proposes a scenario of problem solving in basic electrical circuits based on an e-learning system to assess students skills in solving the problem through the use of the e-learning system. Through cooperation between the teacher and the students and among the students themselves, the proposed scenario indicates a high acceptability from the students to acquire cognitive skills; the students present more motivation to use advanced technology during instruction.
The Them And Us Syndrome: Some Opportunities And Threats To Be Faced When Teachers Come From Certain Countries And Students Come From Others
Authors: Velo Veronica
Published: March 2016

Switzerland is a country with particularly strong immigration regulations, which obliges Hospitality Schools to very often restrict their recruitment for instructors to the local labour market. The students, however, mostly come from distant countries. These students naturally bring their own cultural backgrounds and mental programming, which is not necessarily compatible with those of their lecturers.  This paper will study potential areas of misunderstandings and communication problems between students and teachers interacting in Swiss Hospitality Management Schools, due to their different cultural backgrounds.

Published: March 2016

Educators have a responsibility to not only their students as well as their institution but to society as a whole to provide the best education possible for each and every student.  The burden placed on educators is heavy but the implications are boundless.  Therefore, it is vital for educators to be good at what they do.  Surveys of schools across the United States indicate that a substantial group of educators at all levels lack the skills in basic education.  It is necessary for educators at all levels to successfully master the five basic guidelines of teaching in order to be successful.   The five guidelines for all educators are:#1 Know your Subject, Don’t be a Know it All #2 Be “With It”#3 Be A “Tech-Y” #4 Be in Control of the Class, not Controlling #5 Be Friendly, Not their Friend.
Looking For Niches In All The Right Places: Designing An MBA Program For The Next Decade
Authors: Phelps Raymond A. , Aggarwal Ajay K. , Taylor Patrick A.
Published: March 2016

In an over-built, mature industry as is graduate management education it is increasingly important that schools find the right niche at which to target their MBA programs.  However, the literature is largely silent as to how a school might go about the process of finding the right niche for its MBA.  Using gap analysis and data from Occupational Outlook Handbook, we develop a process for identifying future employment trends as a means of identifying promising niches toward which to orient an MBA program.  This is an important exercise for those who design MBA programs, especially in light of the AACSB/International’s current focus upon continuous improvement among its member institutions.  Even if accreditation standards did not require it, the rapidly changing business climate makes continually upgrading MBA programs a necessity.

Published: March 2016

This paper describes an ongoing EU project concerned with developing an instructional design framework for virtual classes (VC) that is based on the theory of Multiple Intelligences (MI) (1983).  The psychological theory of Multiple Intelligences (Gardner 1983) has received much credence within instructional design since its inception and has been implemented successfully in a wide array of traditional educational settings. Nonetheless, very little research has been carried out on developing frameworks for elevating MI into an e-learning environment. Specifically, the project hopes to adapt and utilize MI theoretical learning principles to create a virtual class specifically designed for instructing health and safety to construction managers. This paper explores the emerging principles from both theory and practice in order to identify the appropriate methodology for the successful incorporation of MI based instructional techniques in the virtual class design. Guidelines are provided on how the MI concept of ‘entry points’ can best be adapted for the specific learners (in this case construction managers) and class content (in this case health and safety). Of particular concern to this papers examination of ‘entry points’ is the potential for the deployment of intelligence profiling research to create a class tailor-made for construction managers while simultaneously adaptive to each learners individual needs. Emerging from this analysis, the paper will provide core recommendations including how to create problem based instructional activities that are directly related to both the participant’s intelligence strengths and to the class content.
Mentoring Undergraduate Researchers: Faculty Mentors Perceptions Of The Challenges And Benefits Of The Research Relationship
Authors: Potter Sharyn J. , Abrams Eleanor , Townson Lisa , Williams Julie E.
Published: March 2016

In the past decade, college and university officials have tried to formalize avenues that provide undergraduate students with opportunities to conduct research, either in direct collaboration with a faculty member or as independent research under the supervision of a faculty member.  Administrators and faculty have worked to institutionalize these programs because they recognize the intrinsic benefits of these faculty student collaborations.  Since most faculty balance a wide range of demands, we wanted to understand how faculty members view these partnerships in the larger context of their work.  In 2008, as the Undergraduate Research Conference at our midsize public New England University entered its ninth year, the evaluation committee administered a survey to examine faculty members’ attitudes toward undergraduate research endeavors. Our results show that faculty felt overwhelmingly positive about their role as mentors. Full professors indicate more satisfaction in this role than associate and assistant professors.
Animations Are Dynamic, Effective Tools For Science Teaching: If You Just Follow The Rules!
Authors: O'Day Danton H.
Published: March 2016

Textbook companies are increasingly including larger numbers of animations as complementary resources for students and teachers. Are all animations useful as teaching tools? The answer is no. Animations can be useful for communicating dynamic events and processes but only when specific rules are followed. The authors review the important components of effective animations and their extensive, original research on the value of animations in learning and long-term memory retention. When the rules are applied, students can learn complex material more easily and retain more of what they have learned in short and long term memory than they can by viewing static textbook figures. Our results also indicate that learning from animations and graphics differs between males and females. Insight gained from student feedback is highlighted with some final comments on future research.
Impacts Of Vocabulary Acquisition Techniques Instruction On Students Learning
Authors: Orawiwatnakul Wiwat
Published: March 2016

The objectives of this study were to determine how the selected vocabulary acquisition techniques affected the vocabulary ability of 35 students who took EN 111 and investigate their attitudes towards the techniques instruction. The research study was one-group pretest and post-test design. The instruments employed were in-class exercises regarding an analysis of word structures and context clues, a vocabulary proficiency test, as well as a questionnaire surveying the students’ attitudes toward the instruction. The pretest and post-test scores were calculated for descriptive statistics and compared using a t-test dependent measure. The study revealed that the students’ post-test score was higher than their pretest score at the .001 level of significance. The results of the questionnaire also illustrated their very favorable attitude toward the instruction of vocabulary acquisition techniques as a whole.

Published: March 2016

Objetivos: a) Determinar el grado de contaminación por monóxido de carbono en corredores aficionados de áreas urbanas y su variación al correr en horarios de alto y bajo tránsito vehicular, b) Definir periodos del día en los que  se puede realizar ejercicio en áreas con tránsito vehicular. Materiales y Métodos: Once corredores aficionados de 23 a 41 años de edad no fumadores, sin historia de cardiopatía ni enfermedades respiratorias; corrieron alrededor del Club “El Golf” en el distrito de San Isidro. Se determinó la concentración sanguínea de carboxihemoglobina de cada corredor antes y después de correr durante 45 minutos en horarios de alto y bajo tránsito vehicular. Simultáneamente se midió la concentración de monóxido de carbono en el aire mediante un analizador portátil en el recorrido. Resultados: En el horario de alto tránsito vehicular se encontró una variación de Carboxihemoglobina estadísticamente significativa (de 0,44% a 0,54%, p=0,039). En el horario de bajo tránsito vehicular no se encontró variación de Carboxihemoglobina estadísticamente significativa (de 0,45% a 0,43%, p=0,722). Al comparar la variación de Carboxihemoglobina de ambos horarios, la diferencia no fue estadísticamente significativa (p=0,219). La medición de monóxido de carbono en el aire no mostró concentraciones constantes. Conclusiones: Este estudio demuestra un aumento en los niveles de Carboxihemoglobina durante el horario de alto tránsito vehicular, sin embargo los valores de Carboxihemoglobina permanecieron dentro de valores normales. En esta zona urbana se puede realizar ejercicio físico al aire libre en cualquiera de los dos horarios, sin riesgo de contaminación por monóxido de carbono.

Published: March 2016

La adquisición de infecciones por patógenos que circulan por la sangre a través de accidentes punzocortantes o exposición de mucosas o piel no intacta a fluidos infectantes, constituye uno de los principales riesgos profesionales para los trabajadores de salud.Se han reportado más de 20 agentes diferentes con la capacidad de transmitirse por esta vía, dentro de los que podemos mencionar al virus de la inmunodeficiencia humana (VIH), virus de la hepatitis B (VHB), virus de la hepatitis C (VHC), virus ébola, virus del dengue, virus herpes 1 y 2, virus de la varicela, Treponema pallidum, Brucella sp, Corynebacterium, Rickettsia sp, Leptospira sp, micobacterias incluyendo tuberculosis, Mycoplasma, Babesia, Plasmodium, Toxoplasma, Cryptococcus y Blastomyces. Muchos de ellos son reportes aislados en trabajadores de salud, personal de bancos de sangre o laboratorios clínicos. Sin embargo, los agentes más importantes por su frecuencia y perjuicio son: el VHB, el VIH y el VHC (1).Lo que presentamos a continuación son conceptos recientes sobre prevención primaria y profilaxis post exposición al VIH, VHB y VHC en accidentes ocupacionales de trabajadores de salud. Hemos hecho nuestro mayor esfuerzo por adaptar guías internacionales a la realidad de nuestro país. Desafortunadamente, muchas de las medidas en el manejo post exposición, actualmente aplicadas en países desarrollados no están disponibles en nuestro país por lo que debemos dar más importancia a conocer y practicar las medidas de prevención pre exposición.

Objetivos: Identificar los factores demográficos y clínicos más frecuentes en recién nacidos con peso menor a 1 000g al nacimiento (extremo bajo peso) fallecidos en la unidad de neonatología del Hospital Nacional Cayetano Heredia. Material y métodos: El estudio diseñado es una serie de casos. Se evaluaron las epicrisis y la base de datos NEOCOSUR de los pacientes con estas características, fallecidos durante la hospitalización, de enero 2000 a diciembre 2004. Resultados: Se encontraron 99 pacientes, con registros completos en 87 de ellos (88% de la muestra). La mortalidad en esta población fluctuó entre 70 y 85%, siendo las siguientes condiciones clínicas más frecuentes: control prenatal inadecuado, edad gestacional menor a 27 semanas, uso de corticoides prenatales, empleo de surfactante, enfermedad de membrana hialina-síndrome de distrés respiratorio y hemorragia intraventricular. Conclusiones: Los cuidados prenatales, el uso de corticoides prenatales y surfactante son factores modificables que tendrían impacto en la mortalidad. Síndrome de Distrés Respiratoriomembrana hialina, sepsis y hemorragia intraventricular, constituyen las entidades de morbilidad más frecuentes. El alcance de este estudio permite formular estas hipótesis. La evaluación de las mismas requiere estudios tipo observacionales y analíticos posteriores.

Objetivos: Comparar el efecto de una solución de dextrosa hipotónica y de una solución isotónica (Hartmann) en los niveles séricos de electrolitos y el equilibrio ácido base en pacientes ancianos hospitalizados. Materiales y métodos: Se evaluaron prospectivamente a 18 pacientes mayores de 60 años hospitalizados en el departamento de Medicina del Hospital Nacional Cayetano Heredia que recibieron fluidos endovenosos al menos por 48 horas. El primer grupo (G1) recibió una solución de dextrosa al 5%, 71 mmol/L de ClNa y 27 mmol/L de cloruro de potasio. El segundo grupo (G2) recibió solución Hartmann, más una solución glucosada de 100 cc al 50% simultáneamente. Se controlaron los valores de los electrolitos y los gases sanguíneos a las 0, 24 y 48 horas de iniciada la observación. Resultados: Ambos grupos presentaron condiciones comparables al ingreso. A las 48 horas los valores del sodio para el G1 fueron 134,5±4,4 mEq/L y para el G2 140±2,4 mEq/L (p<0,01), el pH del G1 fue 7,32±0,07 y el del G2 fue 7,4±0,03 (p<0,01), y el bicarbonato fue 16,6±2,2 mEq/L para el G1 y 22,3±1,6 mEq/L para el G2 (p<0,001). La diferencia entre los valores a las 0 (delta) y 48 horas fueron: sodio –6,1±3,78(G1), 0,9±2,25(G2) en mEq/L, (p<0,001); potasio 0,01±0,43(G1), -0,61±0,56(G2) en mEq/L, (p<0,05); pH –0,09±0,07(G1), -0,01±0,04(G2), (p<0,01); bicarbonato –6,34±1,21(G1), -0,27±1,43(G2) en mEq/L, (p<0,001); pCO2 -6,25±5,33 (G1), 1,4±4,52(G2) en mmHg, (p<0,01). Conclusiones: Los pacientes ancianos hospitalizados que recibieron solución de dextrosa hipotónica, tuvieron niveles significativamente menores de sodio, pH, bicarbonato y PCO2 después de 48 horas comparados con quienes recibieron solución de Hartmann. No se observaron diferencias en los niveles de cloruro, pO2 y anion gap.

Authors: Faustino Arias Margot Delia , Tapia Escarcena Nielsen , Benito Aragón Germán
Published: March 2016

Los lípidos en deportistas representan la principal despensa energética y una fuente casi inagotable de energía durante el entrenamiento de resistencia, solo en deportes aeróbicos la demanda energética no produce subproductos que originen fatiga. Objetivos: Describir el perfil lipídico en niños y adolescentes deportistas de las selecciones de natación y tae kwon do del “Club de Regatas Lima”. Material y Métodos: Se realizó un estudio descriptivo, prospectivo de corte transversal. Se evalúo a 77 deportistas, determinándose su perfil lipídico sérico: Colesterol total, HDL-C, LDL-C y triglicéridos en muestra de sangre venosa tomadas en ayuno nocturno de 12 horas y después de 72 horas de terminado el entrenamiento pre-competitivo; el dosaje se realizó enzimáticamente usando el método colorimétrico de punto final.

Authors: Noda Milla Julio Roberto , Perez Lu José Enrique , Malaga Rodriguez Germán , Aphang Lam Meylin Rosa
Published: March 2016

Objetivo: Se realizó un estudio cualitativo para medir el nivel de conocimiento, sobre diabetes mellitus 2 en pacientes hospitalizados del Hospital Nacional Arzobispo Loayza y el Hospital Nacional Cayetano Heredia. Material y métodos: Se realizaron entrevistas individuales que fueron grabadas y transcritas; y posteriormente interpretadas y calificadas. Se recogieron de las historias clínicas datos demográficos, complicaciones y tratamiento para contrastarlas con las respuestas dadas. Se incluyeron 31 pacientes. Resultados: La edad promedio fue 59,16 años. En 4 pacientes (12,9 %) el nivel de conocimiento sobre la enfermedad fue adecuado, en 15 (48,39 %) intermedio y en 12 (38,71 %) inadecuado. No se hallo asociación estadística entre el nivel de conocimiento con ninguna de las variables estudiadas. Conclusiones: El nivel de conocimientos sobre la diabetes en estos pacientes fue insuficiente. La información obtenida sugiere una educación deficiente de parte de los médicos hacia estos pacientes, lo que hace necesario implementar los programas educativos para ellos.

Objetivo: Describir la sensibilidad antibiótica de gérmenes prevalentes causantes de infecciones del tracto urinario en un hospital general. Material y métodos: Se realizó un estudio descriptivo, retrospectivo de serie de casos en el Hospital Nacional Cayetano Heredia . Se analizaron los urocultivos positivos realizados en los meses de enero a junio del año 2008. Resultados: De 1249 urocultivos positivos, se aisló en pacientes no hospitalizados; Escherichia coli 76% seguido de Klebsiella spp. 5% y Citrobacter sp. 3%. Escherichia coli fue sensible a amikacina, nitrofurantoína, ceftriaxona y ciprofloxacino en 93,4%, 88,6%, 78% y 44,5% respectivamente. En pacientes hospitalizados la frecuencia fue; Escherichia coli 49% seguido de Enterococcus spp. 11,39% y Klebsiella spp. 8,42% siendo Escherichia coli sensible a amikacina, nitrofurantoína, ceftriaxona y ciprofloxacino en 88,89%, 75,26%, 43,88% y 26,04%, respectivamente. Nitrofurantoína obtuvo resistencias bajas en hospitalizados 16,49% y en no hospitalizados 6.48% para Escherichia coli. Conclusiones: Se observó que amikacina vuelve a ser una buena opción como tratamiento empírico; así mismo hubo aumento en la resistencia a antibióticos comúnmente usados, sin embargo antibióticos poco usados como nitrofurantoína tienen mejores niveles de sensibilidad para Escherichia coli.
