Authors: Toyama S. , Nishizawa U. , Matsubara O.
Published: September 2018

The world ocean occupies 70 % on the earth and the average sea depth is about 4,000 m. More than 80 percent of it has not been investigated precisely and the bottom shape of the sea has not been mapped. When doing resource-searching in the future, the precise maps must be required. So, the authors have developed a drone movable around 4,000 m deep sea to measure the bottom of the ocean. It is based on spheres, which includes cameras, batteries, some sensors and controllers. It can rotate a spherical rotor sensing widely to obtain the information about the bottom of the sea. At the first step of the research, the authors have made basic experiments of the motor’s performance in water. The authors have obtained the excellent results in maneuverability, temperature durability, and shock resistance of the motor.

Authors: Kateel M. C. Srividyadhare , K. Srikrishnateja , S. I. Raj Arjun , M. K. Rakshith
Published: September 2018

In this paper, a finite element mathematical model to evaluate natural frequencies and Frequency Response Functions (FRFs) of an L-shaped cracked beam structure is established. Dynamics of L-shaped beam structure is a very challenging subject and very little information is reported in literature. L-shaped beam structure is assumed to be fixed at end of the vertical column and free at the other end of the horizontal column. Natural frequencies are evaluated using finite element method in MatLab and simulations using Ansys (Version 18.2) is carried out to validate the mathematical model. Totally 18 cases with different crack positions and three different crack depths are considered for the analysis. Results obtained by both methods are tabulated and find a very good agreement in the results. Reported results can be used as a benchmark for further study of crack propagation and fatigue failure analysis in built-up structures.

Authors: Sturm Martin
Published: September 2018

Linear vibratory conveyors are common equipment to convey goods. They are used in different industries such as for example the building, mining and food industry. The systems are often used for the supply of bulk goods into further processing operations. The goods to be conveyed, typically requesting a heavy-duty design of the conveyor and eccentric excitation drives with relatively high torque. Often the motion of these conveyors is not ideal with reference to the conveying process of the bulk goods. Motion speed and amplitude of the goods are not constant and blocking effects as well as separation effects can occur. The target of this article is to determine a dynamic model for the targeted displacement of the centre of elasticity of a one-mass conveyor, enabling an optimal motion of the conveyor by an optimized set of springs, connecting the conveying element to the frame.

Regioselective Synthesis of Potent 4,5,6,7-Tetrahydroindazole Derivatives via Microwave-assisted Vilsmeier-Haack Reaction and their Antioxidant Activity Evaluation
Authors: Bala Renu , Devi Vandana , Singh Pratibha , Kaur Navjot , Kaur Pawandeep , Kumar Anil , Yadav Ajar Nath , Singh Karan
Published: September 2018

Background: Tetrahydroindazole, a member of the fused-pyrazole system, is a least studied
class of heterocyclic compounds owing to its scarcity in nature. However, a large number of synthetically
prepared tetrahydroindazoles are known to show a variety of biological activities such as interleukin-
2 inducible T-Cell kinase inhibitors, AMPA receptor positive allosteric modulators, antitumor,
antituberculosis, anti-inflammatory and antimicrobial activities. Vilsmeier-Haack reaction is one of the
most important chemical reactions used for formylation of electron rich arenes. Even though Vilsmeier-
Haack reaction was studied on a wide variety of hydrazones derived from active methylene
compounds, literature lacks the examples of the use of 4-substituted cyclohexanones as a substrate for
the synthesis of 4,5,6,7-tetrahydroindazoles. The study of the reaction of Vilsmeier-Haack reagent with
hydrazones derived from cyclic keto compounds having active methylene has been considered the interested
topic of investigation. In the present study, ethyl cyclohexanone-4-carboxylate was treated
with one equivalent of various hydrazines for two hours and the resulted hydrazones were further
treated with an OPC-VH reagent (Vilsmeier-Haack reagent isolated from phthaloyl dichloride and N,Ndimethylformamide)
afforded 4,5,6,7-tetrahydroindazoles in excellent yields. The synthesized compounds
4a-f and 5a-f were screened for their antioxidant activities using the DPPH radical scavenging
assay. The target compounds were synthesized regioselectively using 4+1 approach in excellent yields.
A number of experiments using both conventional heating as well as microwave irradiation methods
were tried and on comparison, microwave irradiation method was found excellent in terms of easy
work up, high chemical yields, shortened reaction times, clean and, no by-products formation. Some of
the synthesized compounds showed significant antioxidant activity. The microwave assisted synthesis
of 4,5,6,7-tetrahydroindazoles from ethyl cyclohexanone-4-carboxylate has been reported under mild
conditions in excellent yield. Easy work up, high chemical yield, shortened reaction times, clean and
no by-products formation are the major advantages of this protocol. These advantages may make this
method useful for chemists who are interested in developing novel 4,5,6,7-tetrahydroindazole based
drugs.

Authors: Muddapur Dr.K. G. , Patil Dr.Uma A.
Published: September 2018

Grahani is the seat of Agni and it is so called because of holding up the food. The term Grahani Dosha implies the malfunctioning of Agni. Improper digestion of ingested food causes Grahani Dosha. If left untreated it finally leads to Grahani Roga. Muhurbadha and Muhurdrava Mala Pravrutti is the main Lakshana and associated with symptoms like Udarashoola, Arochaka, Sharirika Balakshaya, Asthi Parvashoola, Avipaka etc. As Agnimandya is the main cause, the first line of treatment is to correct the Dusti of Agni. Shuntyadi Churna and Mustakadi Churna have the qualities of Deepana, Pachana, Grahi, etc. and can be used in Sarvagrahani Chikitsa. This study is undertaken to clinically analyze the independent effect of Shuntyadi Churna and Mustakadi Churna in Grahani Roga. The study shows that both Shuntyadi Churna and Mustakadi Churna are effective in relieving the symptoms of Grahani Roga.

Published: September 2018

Modern science has made tremendous progress and acquired deep knowledge about Micro-organisms. But still infections caused by these, still ranks very high as a cause of death in the world. Even though there are number of Antibiotics present and new are being developed, the Micro-organisms are developing resistance towards these Antibiotics, hence there is need to find out a better medicine which can contradict all the Micro-organisms. In Ayurveda various formulations are mentioned and well documented, those are having the antimicrobial effect. This is the time to re-establish the effect of antimicrobial agents by proving it clinically or experimentally. Their effect will be evaluated by comparing with the standard drugs (Ciprofloxacin, Ampicillin,) which are in use now. The formulation taken for the study is Bhagottar Gutika. Its antimicrobial study will be done experimentally by adopting cup-plate diffusion method. The study does not require any investigation or intervention to be conducted on patients or animals.

The correlation between these two disease mainly focuses on the similarity between the symptoms, site of attack and re-occurrence pattern. Here an attempt is made in this article to discuss the various concepts in the relation between Avarana, Serum Uric Acid and the micro pathogenesis in Vatarakta / Gouty Arthritis.
Aahara as Aushadha - Reviving the concept of Aushadha Siddha Yavagu
Authors: R. Dr. Swathi , K. Dr. Malathi , Sharma Dr. Sanketh V.
Published: September 2018

The current trend in Ayurveda practice is more medicinal approach than wholesome one. The importance of Aahara (dietary aspect) has been compromised to a great extent owing to the convenience of patient as well as the ignorance of the physician. To bring back the wholesome practice into vogue, there is a need for developing techniques to keep-up with the fast paced modern life yet conserve the classical foundations. Through this study we try to introduce the concept of ‘Instant Aushadha Siddha Yavagu‘, and how it can be made. The sample was prepared by adopting classical methods of Yavagu preparation, along with simultaneous use of certain modern techniques of drying in hot air oven. The prepared product served the main intention of reducing the efforts at the receiving end; without compromising on the quality of product. Thus it can be concluded that further researches can be carried out in this direction to bring out such products for benefits of the society. As this field is relatively unexplored there is a wide scope for exploration.
A Review on Sneha Kalpana in Ayurveda
Authors: Thakur Dr. Tejas D. , Mane Dr. R. G.
Published: September 2018

Ayurveda the science of life, uses natural resources to fulfill the fundamental objectives i.e. Swasthya Rakshanam and Vyadhi Prashamanam. Ayurveda has been given the greatest emphasis to comprehensive knowledge of drugs. This science of manufacturing drugs is divided under two branches as Rasashastra and Bhaishajya Kalpana. Bhaishajya means medicine and Kalpana means forms. Hence Bhaishajya Kalpana means branch of Ayurvedic medicine which deals with preparation of medicines by the use of herbal drugs. Bhaishajya Kalpana includes Panchavidha Kashaya Kalpana as Swarasa, Kalka, Kwatha, Hima and Phanta. Bhaishajya Kalpana also includes preparation of various forms of medicine such as Churna, Guti, Vati, Ghruta Paka, Tail Paka, Lepa, Asava, Arishta etc. Sneha Kalpana is a group of products of medicated Taila and Ghruta. Quality and quantity of lipid soluble extract of medicinal ingredients varies, as per methods, types of material and ratio of material with reference to Sneha Dravya. That is why various methods of Sneha Paka are described in classical texts of Ayurveda. Classically these formulations are having a longer shelf life in comparison to other Ayurvedic herbal medication form. It is only Kalpana which is used through all four modes of administration of such formulations i.e. Pana, Abhyanga, Nasaya and Basti. So to review all these methods at a glance is main aim of this article.

Bordando una etnografía: sobre cómo el bordar colectivo afecta la intimidad etnográfica
Authors: Pérez-Bustos Tania , Piraquive Alexandra Chocontá
Published: September 2018

El artículo reflexiona sobre dos experiencias etnográficas que se acercan a iniciativas de bordado colectivo, buscando comprender lo que este hacer textil en común conlleva, y preguntando cómo ellas mismas devienen etnografías en el estar y acompañar a estos espacios de bordado colectivo. Nos centramos en dos movimientos. Por un lado, nos referimos a lo que el bordar colectivo gesta: tanto las identidades de género que contribuye a (re)configurar, las intimidades que propicia, los espacios sanadores a los que da lugar, así como lo que el bordado colectivo expresa y cómo lo que dice está construido por una dimensión afectiva y de género que deviene en el bordar con otras. En segundo lugar, damos cuenta de cómo eso que el bordado colectivo gesta, afecta el proceso de escritura etnográfica. Nos referimos aquí a las formas en que el bordar con otras entreteje a la etnografía misma.

Authors: Gargoubi Sondes , Chaouch Walid , Stambouli Mouna , Bhouri Naoufel , Boudokhane Chedly , Zouari Riadh
Published: September 2018

Usually, new artificial leather items are very smelly because they have been created using numerous chemicals. Their full smell remains until they become old enough. Removal of unpleasant chemical odor is important to preserve the safety and health at workplaces, to meet the demands of consumers and to develop marketing strategies. In this work, we focus on studying odor abatement using natural and synthetic fragrances. We have found that, in well-defined conditions, both types of fragrances efficiently hide the chemical odor. However, the use of the synthetic one combined with paraffin oil was more effective and cheaper.
MUSIC AND MATHEMATICS: SOME REMARKS ON THE IDEAS OF SPACE AND FORM
Authors: CRISTE Cristina
Published: September 2018

Mathematics has been used to describe, analyse and create music for millennia. The use of specific mathematical apparatus is manifest in the organization of basic musical notions into forms or objects that inhabit a sonorous landscape. The collecting of musical units into a set constitutes a starting point for analysing a musical object under different mathematical structures, and although there is no unified approach, musical analysis and composition use geometry and discrete mathematics to describe different musical relations (particularly group theory) in the process of modelling the basic elements of music, such as scales, intervals, chords or rhythms.
DOTTRINA DELLA CREAZIONE E L’EVOLUZIONISMO
Authors: IACOB Iosif
Published: September 2018

Doctrine of creation and evolution. The dialogue between science and faith has seen many fluctuations in different historical periods. Currently, as recalled by Pope Benedict XVI in a speech in 2008, in an audience granted to the Pontifical Academy of Sciences, there isn’t any kind of conflict between how the mystery of creation is perceived through faith and the proofs of empirical science. Autonomy is an essential feature that must be the root of a fruitful dialogue. Any analysis and study that considers the belief in God – the Creator and the scientific research must take into account the different characteristics and meanings of both faith and science. Theology does not seek so much a theory of the origin of the world in a technical sense, but rather a relation between God - the Creator and the world as his creation. Science can only analyze empirical aspects and can investigate categorical causes, without reaching the notion of creation in the theological sense, but relying only on experimental aspects.
THE CHRISTIAN CONCEPT OF THE HUMAN NATURE IN THE FACE OF FRIEDRICH NIETZSCHE’S ATHEISM – BERNHARD WELTE ON “THE DEATH OF GOD” AND “ÜBERMENSCH”
Authors: VINCZE Krisztián
Published: September 2018

The most widely known sentence in The Gay Science is ”God is dead.” Nietzsche himself is fully aware that with the disappearance of God, all human ideas and acts lose their foundations, and what was formerly built upon God as a basis, suddenly loses its footing, and floats in the endless nothing. The rejection of the Christianity, is the moment for Nietzsche when man re-gains his free will and abandons all limiting powers over his all-surpassing self, and starts his journey to the new quality of becoming Übermensch. The willpower, the will to existence and the will to power play central roles in the birth of the Übermensch. Bernhard Welte reminds us that man’s desire to exist is an a priori that Christian anthropology also finds important. Man is created in the image and likeness of God, and carries on himself the shine of the face of God. Our want of existence is indeed an a priori of our selves, it is indeed the dynamism which is the source of all our specific willful actions, then this will is, in the interpretation of Christian anthropology, a will to bring us closer to God. Man wants to be God somehow, moves towards a divine existence. Consequently, atheism is a human capability and opportunity possibly derived from the innermost essence of the human race. There is a divine element in every human being, that is why man wants to become god, and that is why man makes himself godless when, in his rebellion, he rejects God.
Is it really possible that the most extreme atheism is fed by man’s divine origin and roots? Bernhard Welte provides an explanation through the dialectics of the original, essential structure of human existence - this explanation is presented in the following paper.
COMMUNIO IM KONTEXT DER EKKLESIOLOGIE... DES II. VATIKANISCHEN KONZILS
Authors: VIK János
Published: September 2018

Communio in the Context of Vatican II’s Ecclesiology. Since the Second Vatican Council, the Church can be considered as communion. This essay attempts to provide a brief, primarily linguistically and phenomenologically oriented study of the word communio in order to point out the meaning and usefulness of the concept of communio for the Christian faith by emphasizing communio as the key concept of faith. In this sense, this essay seeks to contribute towards demonstrating that the idea of communio / koinonia is both plausible and relevant for the theology or ecclesiology of the third millennium, as well as for a successful communio practice.
O bilinguismo greco-romano na tradução latina do ΛΟΓΟΣ ΤΕΛΕΙΟΣ: enfoques sociolinguísticos na análise do Asclepius Latinus
Authors: Pessoa de Lira David
Published: September 2018

O presente artigo trata de um objeto da área de Língua e Literatura Latinas. Sendo assim, objetiva-se apontar os helenismos que permanecem na tradução latina do Asclepius, levando em consideração os fragmentos herméticos gregos do Λόγος Τέλειος que se preservaram. Especificamente, analisam-se os aspectos do bilinguismo na tradução latina: a interferência, a comutação de código, a comutação de alfabeto e os empréstimos no Asclepius Latinus. Em particular, este artigo demonstra que as adaptações da tradução do grego para o latim não são apenas resultados de adição ou subtração de palavras e sentenças. A incidência de palavras gregas como uma espécie de code-switching, seguidas de explicações, exemplificações, reiterações, reformulações e marcas de paráfrase, demonstra justamente que as adaptações (adições) não só ocorrem com palavras e sentenças, mas também com fragmentos de texto.
The iconography of death: continuity and change in prothesis ritual through iconographical techniques, motifs, and gestures depicted in Greek pottery
Authors: Souza Camila Diogo de , Dias Carolina Kesser Barcellos
Published: September 2018

Prothesis scenes have been a controversial and debated theme of iconographical approaches to Greek pottery analyses. Focused on meaning and historical references these studies usually have considered pictorial elements isolated in a particular pottery production and style, Attic Geometric for instance. This paper intends to analyze and discuss some iconographical elements such as technique of production, style, motifs and gestures taking into account a broader perspective and chronology, including vases and terracotta pinakes from the Geometric to the Classical Period. This approach to prothesis ritual scenes allow us to point out continuities and changes in the funerary ritual iconographic representation itself and its social and cultural meanings.

O presente artigo faz uma homenagem ao professor Marcelo Pimenta Marques, ressaltando seu caráter como parte de seu legado a seus alunos e amigos. Destaca, na filosofia platônica, as concepções de virtude e vício, vida e morte “na” psykhé, como “estados de alma” conquistados segundo o grau de educação e amizade dos três gêneros da alma (tò logistikón, tò thymoeidés, tò epithymetikón), de autoconhecimento e conhecimento dos diferentes graus de Ser. Tal leitura reafirma a defesa de nossa tese de doutoramento que aponta a teoria da alma triádica como base da teoria ético-política de Platão, presentes sobretudo nos diálogos República e Leis.
Parameter Preservation at the Syntax-PF Interface: The Ba Construction Revisited
Authors: Shu Chih-hsiang
Published: September 2018

In this paper, I argue for an analysis that treats the ba construction in Chinese as a case of shape preservation-induced movement structure. Specifically, the robust preverbal adverbial and PP expressions and the mandatory ba-DP movement in ditransitive structures are both derived from a violable head directionality macroparameter under the Symmetrical Syntax Hypothesis, which allows directionality parameters to examine word order throughout the derivation. In addition to being able to capture the parallel syntactic properties of Scandinavian object shift, this account receives further empirical support from word order facts of Archaic Chinese and Bambara.
Um adendo moderno
Authors: Puh Milan , Pitol André
Published: September 2018

O presente artigo examina as relações entre arte e política presentes nas exposições da representação da Iugoslávia nas Bienais Internacionais de Arte de São Paulo nas décadas de 1950 e 1960, e parte de um enfoque específico: o grupo de pinturas e gravuras apresentadas entre a segunda e a sexta edição da mostra e que foram adquiridas por meio dos prêmios de aquisição para as coleções do MAM São Paulo e de Ciccilo Matarazzo-Yolanda Penteado, doadas em 1963 à USP como parte do acervo que originou o Museu de Arte Contemporânea. O conjunto de 16 trabalhos realizados por oito artistas de seis países da então República Socialista Federativa Iugoslávia são indicativos de um importante episódio do modernismo nas artes plásticas, e abrange os debates relacionados ao embate figuração e abstração, arte fantástica, arte naïf e referências folclóricas. Esta também é uma oportunidade de compreender melhor as configurações institucionais entre Brasil e Iugoslávia e as maneiras pelas quais a política cultural iugoslava se fez presente no Brasil no pós-Segunda Guerra Mundial, período do qual perdura hoje a narrativa de polarização entre as potências da Guerra Fria.
Ecopolíticas, no linealidad y poshumanismo
Authors: Bernal Raúl Niño
Published: September 2018

La discusión que se plantea en torno a la Ecopolítica interrelaciona las perspectivas no humanas con las artes y el conjunto de los procesos de la vida artificial, lo cual se hace visible en los procesos creativos.  Asimismo en los cambios de paradigma, cuyos procesos no lineales ponen en tela de juicio la naturaleza humana y las transformaciones de la economía. Así las cosas, se plantean nuevas relaciones desde los principios ecofilosóficos para comprender las condiciones del posthumanismo en una era de transformaciones tecnológicas, en los universos digitales, computacionales y genéticos que conducen a un proceso paulatino de ecologías artificiales.  Todo lo anterior propone ámbitos novedosos y retos que llaman la atención de las dimensiones de la política desde los sistemas no lineales.
El cambio organizacional y la universidad pública
Authors: De Vries Meijer Dr. Wietse
Published: September 2018

En este texto se analiza lo que ha pasado –y lo que no ha pasado– en los últimos diez años en la educación superior mexicana, particularmente en las universidades públicas (recurriendo al caso ilustrativo de la Benemérita Universidad Autónoma de Puebla). Para ello, se propone una forma distinta para analizar el cambio organizacional, enfocando los cambios en la perspectiva del entorno cambiante y la respuesta de la organización frente a este ambiente. Ese enfoque analítico brinda pautas no sólo para describir los cambios, sino para poder hacer comparaciones con otras instituciones y países, o para poder juzgar la calidad o la dirección del cambio, así como para poder saber si un cambio fue una innovación o un paso hacia atrás. Así, se vislumbra que frente a los cambios en el mundo, y dentro de México, las universidades públicas nacionales han sido muy reacias al cambio; y cuando éste se ha dado, ha sido de una forma extemporánea, incongruente con los cambios en otras regiones.AbstractThis text analyzes what has and what has not happened in Mexican higher education during the last 10 years, particularly what has happened in the public universities (the illustrative case of the Benemérita Universidad Autónoma de Puebla). For that purpose, we propose a different way of analyzing organizational change, by focusing on the changes in the perspective of a changing environment and the response of the organization to said environment. That analytical focus offers guidelines not only to describe the changes but also to be able to make comparisons with other institutions and countries, or to be able to judge the quality or the direction of the change, as well as to be able to know whether a change was an innovation or a step backward. Thus, we see vaguely that in the face of the changes in the world, and in Mexico , the public national universities have been reluctant to change; and when change has occurred, it has done so inopportunely and incongruently with the changes in other regions.

Alternativa para la formación del estudiante mediante el proceso didáctico de la Física en el Nivel Medio Superior
Authors: Ruiz Mendoza Dr. Juan Carlos , Torres Bugdud Dr. Arturo , Álvarez Aguilar Nivia
Published: September 2018

En el presente artículo se fundamenta una concepción para favorecer la formación integral del estudiante del Nivel Medio Superior, mediante el proceso didáctico de la Física. Con este propósito se expone una concepción orientada a favorecer una formación más completa en el estudiante a través del citado proceso. Su elaboración se realizó con el uso del método sistémico estructural y está integrada por tres subsistemas que guardan una estrecha relación entre sí. Se usaron diferentes métodos y técnicas tales como: método histórico-lógico, análisis-síntesis, sistémico estructural, la observación participante, cuestionarios a estudiantes y docentes y composiciones como técnica para el análisis de los productos de la actividad.
Cómo vivo la escuela: oficio de estudiante y micro-culturas juveniles
Authors: Martínez Álvarez Domingo Balam
Published: September 2018

El libro reseñado nos explica cómo es que los escolares desarrollan su trabajo en las aulas y fuera de ellas, qué pasa en ese tránsito por el nivel de educación medio superior aquí en México, cuál es su experiencia escolar en torno a ello; qué les gusta y qué no, cuáles son las cosas que les provocan sentimientos de miedo y, desde el lugar que ocupan en la sociedad, cuáles son las prioridades que tienen; de cómo viven su participación en los innumerables concursos que las zonas escolares promueven: de matemáticas, oratoria, ortografía, escoltas, tablas gimnásticas, etcétera. Toda esta interpretación está atravesada por otra perspectiva: la del enfoque de los estudios sobre juventud.AbstractThe reviewed book explains how students develop their work in and out of the classroom, what happens in the passage through the high school education level in Mexico, how is the academic experience about it, what they like and do not, which are the things that can cause fear and, from their place in society, which are their priorities, how do they live their participation in contests promoted by school areas: maths, oratory, spelling, escort, gymnastic tables, etcetera. All this interpretation is crossed by another perspective: the focus of studies about youth.Recibido: 10 de marzo de 2010Aceptado: 12 de marzo de 2010
Propiedades psicométricas de un instrumento para medir la disposición hacia el estudio

Published: September 2018

El presente trabajo reportó el análisis de validez de un instrumento para medir la disposición hacia el estudio en estudiantes de secundaria. Se seleccionó una muestra probabilística de 306 estudiantes de una escuela secundaria pública del sur de México. Los análisis de validez de constructo arrojaron la presencia de cuatro factores que explican el 58.3% de la varianza total del constructo (motivación intrínseca hacia el estudio, compromiso con la tarea, autorregulación y adaptación). Se concluye que el instrumento cuenta con los criterios de validez para justificar la necesidad de otros estudios que fortalezcan sus propiedades psicométricas y para ser usado con precauciones en la medición de la disposición hacia el estudio.AbstractThis paper describes a validity and reliability analysis of an instrument designed to measure disposition of study in secondary school students. A probabilistic sample of 306 students was selected from a secondary public school in southern Mexico. The construct validity analysis showed the presence of four factors explaining 58.3% of total variance. It was concluded that the instrument complies with validity criteria to justify further studies to strengthen its psychometric properties and to be used with care in research regarding study disposition as well.Recibido: 6 de enero de 2010Aceptado: 6 de septiembre de 2010
Conocimientos del profesorado universitario en herramientas telemáticas
Authors: Muñoz Carril Dr. Pablo César , González Sanmamed Dra. Mercedes
Published: September 2018

En el presente artículo mostramos los resultados obtenidos en una investigación de carácter cuantitativo llevada a cabo con profesores de primer, segundo y tercer ciclo de la Universidad de A Coruña que utilizaban sistemas de e-learning como complemento a sus clases presenciales. Uno de los principales propósitos del estudio ha sido recoger las voces del profesorado en cuanto a su nivel de conocimiento en herramientas teleformativas. También se ha analizado si existían diferencias en cuanto a los niveles de conocimiento del profesorado universitario en función de sus características personales (“sexo” y “edad”) y profesionales (“experiencia docente”, “experiencia docente universitaria utilizando entornos virtuales” y “categoría administrativa”). Los resultados obtenidos reflejan que el nivel de conocimiento del profesorado en herramientas teleformativas es bajo, siendo el correo electrónico y el chat, las utilidades que han alcanzado mayor puntuación. Por último, los análisis inferenciales realizados pusieron de manifiesto que es el profesorado más joven, en régimen de contrato, con menos años de experiencia y con mayor tiempo utilizando entornos virtuales, el que posee mayores niveles de conocimiento de las herramientas teleformativas.AbstractThis paper presents the findings from a research aiming to study the perception of the knowledge level of the use of e-learning tools among faculty from the University of A Coruna, belonging to both undergraduate and graduate programs. Based on a quantitative methodological approach, differences in knowledge levels are analysed, in order to identify relationships according to personal (sex and age) and professional (teaching experience, university teaching experience using virtual environments and position) features. The results show that the level of knowledge of faculty in e-learning tools is low, being e-mail and chat the utilities that have achieved the highest score.An inferential analysis also shows that untenured younger teachers, with fewer years of experience and using virtual environments for a longer period of time, score higher levels of knowledge of the e-learning tools.Recibido: 16 de agosto de 2010 Aceptado: 24 de enero de 2011
