REDUCTION OF FORMALDEHYDE LEVELS IN TOFU USING WHITE TURMERIC (Curcuma mango) WITH SPECTROPHOTOMETRY
Authors: Yazid Edy Agustian , Putri Evariza Vyanto
Published: November 2017

Tofu is a type of traditional food that is widely consumed by the community. Tofu is susceptible to damage so manufacturers know often add preservatives such as formaldehyde. Formaldehyde or known as formalin is not included in the list of food additives as they are toxic and harmful to human health. This study aims to determine the decrease in formalin content in tofu using the addition of white turmeric. The method used by spectrophotometry with chromatropic acid as reagent and absorbance is measured at a wavelength of 570 nm. Based on the research results obtained formalin level on tofu before added white turmeric equal to 10.279 ppm. After addition of white turmeric solution with concentration 2.5%; 5% and 7.5%, respectively with soaking for 5 minutes, 10 minutes and 15 minutes obtained the largest decrease of formalin at 7.5% concentration for 15 minutes at 62.8%. From these results it can be concluded that with the addition of white turmeric can reduce formalin in tofu.

OPTIMIZATION AND QUERCETIN RELEASE TEST OF MORINGA LEAF EXTRACT (MORINGA OLEIFERA) IN GEL-MICROEMULSION PREPARATION
Authors: Bhagawan Weka Sidha , Atmaja Ria Ramadhani Dwi , Atiqah Sri Nur
Published: November 2017

Quercetin is a flavonoid compound of the flavonol group that has various biological activities for health. Moringa leaf is one of the plants rich in quercetin which is about 384.61 mg / 100 g. Quercetin is practically insoluble (4.5 μg / mL). To increase the solubility and release of quercetin microemulsion may be used as Drug Delivery Systems formulated with gels for transdermal use.

The aim of this research is to obtain optimum combination formulation of surfactant (tween 80): cosurfactant (propylene glycol) to form optimal microemulsion system, to find out the characteristics of the preparation and to find out the rate of quercetin release of Moringa leaf extract (M. oliefera) in a gel-microemulsion preparation compared with a control gel (without microemulsion) using an HPMC (Hydroxypropyl methylcellulose) gel basis.

The result shows that optimal concentration tween 80 comparison : propylene glycol to form optimal microemulsion system up to 30%: 20 % with VCO (virgin coconut oil) oil phase 5%. The characteristics observed including organoleptic, pH, viscosity, and stability are showing optimal condition. The average of quercetin content in gel-microemulsion preparation was 2,22 ± 0,077 ppm and on control gel was 2.37 ± 0.042 ppm. Quercetin release test using Franz diffusion cell using cellophane membrane, saline phosphate buffer pH 7,4 ± 0,05 and temperature 37 ± 0,5 °C for 6 hours. The average quercetin release flux in the gel-microemulsion preparation was 9.436 ± 1.178 (μg/cm 2/min1/2) and the control gel was 5,816 ± 0.485 (μg/cm2/min1/2).Based on these results it can concluded that the microemulsion gel preparation gives significant difference of quercetin flux rate compared with gel preparation.

This paper considers conjectural variations equilibrium (CVE) in the one item market with a mixed duopoly of competitors. The duopoly is calledsemi-mixedbecause one (semi-public) company’s objective is to maximize a convex combination of her net profit and domestic social surplus (DSS). The two agents make conjectures about fluctuations of the equilibrium price occurring after their supplies having been varied. Based on the concepts of theexteriorandinterior equilibrium, as well as the existence theorem for the interior equilibrium (a.k.a. the consistent CVE, or the exterior equilibrium withconsistent conjectures) demonstrated in the authors’ previous papers, we analyze the behavior of the interior equilibrium as a function of the semi-public firm’s level of socialization. When this parameter reflected by the convex combination coefficient tends to 1, thus transforming the semi-public company into a completely public one, and the considered model into the classical mixed duopoly, two trends are apparent. First, for the private company, the equilibrium with consistent conjectures (CCVE) becomes more attractive (lucrative) than the Cournot-Nash equilibrium. Second, there exists a (unique in the case of an affine demand function) value of the convex combination coefficient such that the private agent’s profit is the same in both of the above-mentioned equilibrium types, thus making no subsidy to the producer or to the consumers necessary. Numerical experiments with various mixed duopoly models confirm the robustness of the proposed algorithm for finding the optimal value of the above-mentioned combination coefficient (a.k.a. the semi-public company’s socialization level).
Improving Interval Weight Estimations in Interval AHP by Relaxations
Authors: Inuiguchi Masahiro ,   Osaka University 1-3 Machikaneyama, Toyonaka, Osaka 560-8531, Japan, Innan Shigeaki
Published: November 2017

From the viewpoint that the vagueness of a decision maker’s evaluation causes inconsistencies in a pairwise comparison matrix, interval weights have been estimated using the interval AHP. However, the estimated interval weights are often insufficient to express the vagueness of the decision maker’s evaluation. We propose three modified estimation methods for interval weights. The first is based on a relaxation of the optimality of estimated interval weights in the conventional method. The second employs a modified objective function and the third is based on a relaxation of the optimality with respect to the modified objective function. Two of the proposed methods include parameters with degrees of relaxation. Through numerical experiments with 100,000 pairwise comparison matrices generated from 100 true interval weight vectors, we demonstrate the advantages of the proposed methods over the conventional method, and determine the best method and the suitable degree of relaxation.
Approximate Determination ofq-Parameter for FCM with Tsallis Entropy Maximization
Authors: Yasuda Makoto ,   National Institute of Technology, Gifu College Kamimakuwa 2236-2, Motosu, Gifu 501-0495, Japan
Published: November 2017

This paper considers a fuzzyc-means (FCM) clustering algorithm in combination with deterministic annealing and the Tsallis entropy maximization. The Tsallis entropy is aq-parameter extension of the Shannon entropy. By maximizing the Tsallis entropy within the framework of FCM, statistical mechanical membership functions can be derived. One of the major considerations when using this method is how to determine appropriate values forqand the highest annealing temperature,Thigh, for a given data set. Accordingly, in this paper, a method for determining these values simultaneously without introducing any additional parameters is presented, where the membership function is approximated using a series expansion method. The results of experiments indicate that the proposed method is effective, and bothqandThighcan be determined automatically and algebraically from a given data set.

Routing mechanism is a key issue in Wireless Sensor Networks, and rumor routing protocol can reduce energy consumption and extend the lifecycle of network with unicast mechanism. However, in Rumor Routing protocol, the transmission path of event message is not optimal and random forwarding mechanism will lead to routing loop. In this paper, we investigate Rumor Routing protocol, and propose an improved rumor routing protocol based on optimized intersection angle theory. Localization technology and vector intersection angle mechanism are brought into the new protocol as two metrics of route selection. The new mechanism can reduce the energy consumption of data transmission. We compare Rumor Routing protocol, GPSR protocol, a Rumor Routing-based protocol, and the improved protocol. Results of simulation experiments indicate that the improved routing protocol can reduce the energy consumption of routing path and extend the lifecycle of network.

Existing cross-media retrieval methods usually learn one same latent subspace for different retrieval tasks, which can only achieve a suboptimal retrieval. In this paper, we propose a novel cross-media retrieval method based on Query Modality and Semi-supervised Regularization (QMSR). Taking the cross-media retrieval between images and texts for example, QMSR learns two couples of mappings for different retrieval tasks (i.e. using images to search texts (Im2Te) or using texts to search images (Te2Im)) instead of learning one couple of mappings. QMSR learns two couples of projections by optimizing the correlation between images and texts and the semantic information of query modality (image or text), and integrates together the semi-supervised regularization, the structural information among both labeled and unlabeled data of query modality to transform different media objects from original feature spaces into two different isomorphic subspaces (Im2Te common subspace and Te2Im common subspace). Experimental results show the effectiveness of the proposed method.

The paper introduces a rough set model to analyze an information system in which some conditions and decision data are missing. Many studies have focused on missing condition data, but very few have accounted for missing decision data. Common approaches tend to remove objects with missing decision data because such objects are apparently considered worthless from the perspective of decision-making. However, we indicate that this removal may lead to information loss. Our method retains such objects with missing decision data. We observe that a scenario involving missing decision data is somewhat similar to the situation of semi-supervised learning, because some objects are characterized by complete decision data whereas others are not. This leads us to the idea of estimating potential candidates for the missing data using the available data. These potential candidates are determined by two quantitative indicators: local decision probability and universal decision probability. These potential candidates allow us to define set approximations and the definition of reduct. We also compare the reducts and rules induced from two information systems: one removes objects with missing decision data and the other retains such objects. We highlight that the knowledge induced from the former can be induced from the latter using our approach. Thus, our method offers a more generalized approach to handle missing decision data and prevents information loss.

There are two main features of our approach. The first is the combination of B&P and metaheuristics, and the second is the implementation of an efficient B&P algorithm. Through applying our approach to widely used benchmark instances, the effectiveness of our approach is determined.
Online Control of a Virtual Object with Collaborative SSVEP
Authors: Touyama Hideaki ,   Toyama Prefectural University 5180 Kurokawa, Imizu-city, Toyama 939-0398, Japan, Sakuda Mitsuru
Published: November 2017

In this paper, we propose a brain-computer interface (BCI) based on collaborative steady-state visually evoked potential (SSVEP). A technique for estimating the common direction of the gaze of multiple subjects is studied with a view to controlling a virtual object in a virtual environment. The electro-encephalograms (EEG) of eight volunteers are simultaneously recorded with two virtual cubes as visual stimuli. These two virtual cubes flicker at different rates, 6 Hz and 8 Hz, and the corresponding SSVEP is observed around the occipital area. The amplitude spectra of the EEG activity of individual subjects are analyzed, averaged, and synthesized to obtain the collaborative SSVEP. Machine learning is applied to estimate the common gaze direction of the eight subjects with the supervised data from fewer than eight subjects. The estimation accuracy is perfect only in the case of the collaborative SSVEP. One-dimensional control of a virtual ball is performed by controlling the common eye gaze direction, which induces the collaborative SSVEP.

Indonesia is a country with a high earthquake intensity which brings significant impact on a lot of infrastructure damage, including building houses in every incident of a natural earthquake. The assessment model on earthquake damage with a fuzzy system has previously developed. It was aimed to assess the building damage rate after earthquake events, and it has a particular weakness on both the criteria used and the rate of model accuracy. The study was conducted to develop fuzzy inference model to determine the building damage hazard, especially for non-engineered building houses on a particular earthquake event (mitigation). The model was is a three-stage fuzzy rule-based model using a thousand data of building houses damaged as result of the impact of earthquake in Bener Meriah district, Aceh Province, Indonesia in the 2013 event, the peak ground acceleration (PGA) data, slope data extracted from 30 meters digital elevation model (DEM) and distance from major fault that was extracted from geological structure map. The main contribution of the research that has been done is to develop the function and fuzzy membership for each determinant variable of building house damage hazard and three stage fuzzy inference process to determine the building house damage hazard as an impact of an earthquake event. Using four hundred data of building houses damage as an impact of the earthquake at the same location, a three-stage fuzzy rule-based model that has been implemented in the study was proven to be able to determine the level of damaged building houses especially for non-engineered building houses better than the previous models with model performance by 93%.

On the Generalizations of Megrelishvili Protocol for Group Key Distribution
Authors: Arzaki Muhammad
Published: November 2017

This article presents an extension of our previous research in AW17 where we propose two variants of Megrelishvili key distribution schemes and investigate some of their elementary theoretical security analysis. We briefly discuss the two protocols in AW17 and propose another two schemes which are more efficient than the preceding ones. Additionally, we also devise efficient procedures for constructing a new mutual key if the group membership is altered. Furthermore, we discuss the security of the protocols rigorously and we provide a sufficient condition for breaking the protocols by way of solving several instances of Megrelishvili vector-matrix problems (MVMP). We prove that the secret group key can be recovered easily if an attacker can express the sum of the secret exponents of the participants as a linear combination of the secret exponents excerpted from the transmission. Based on this result, we reason that our Megrelishvili key distribution schemes are theoretically at least as secure as the standard two-party Megrelishvili key exchange procedure.

Most of the smoke detection system these days still using sensors that have to receive specific particles before it could give a warning. But, this system takes some time to react and quite difficult to place in spacious room or the outdoor. To overcome this, there is some research that build smoke detection system using many kind video processing technique that could provide early warning. In this research, wavelet energy was used to detect smoke in the video.  To determine candidate blocks in a frame that contain smoke, this research performed background subtraction and color analysis based on HSV color space. Then implementing spatial analysis and spatio-temporal analysis by using wavelet energy method and accumulative motion orientation to detect the smoke. This system using combination of dataset from previous research [1], downloaded from various sources and self-made dataset. Based on testing process using those dataset, this system reaches 91.05% accuracy for block-level and 72.22% accuracy for frame-level.

Ecocriticism and Anthropocentrism in Yann Martel’s Life of Pi
Authors: Vlašković Ilić Biljana
Published: November 2017

Yann Martel’s novel Life of Pi, the winner of numerous prestigious awards, was described as “very bold and extreme with a wonderful central idea” (Irish Examiner 2002). The “central idea” of the novel has been described differently by readers and literary critics around the world. For many, it is Pi’s relationship with the tiger, Richard Parker; for some, it is the decentering of humans in favour of animals; and yet for others, the central idea of Life of Pi lies in Martel’s unusual treatment of religions and their role in human life. In this paper we argue that that the main idea of the novel is Martel’s ecocriticism of humanity in general, and especially the tendency of humans to put themselves at the center of any story, whether about animals or gods. Martel creates a tangled web of many different stories which define Pi’s life in order to prioritize the role of fiction in the development of human personality and dissect the relations between the human, the natural world, and the text. Although he favors the animal story, the final chapter reveals that the only story humans find “real” is the one in which animals are seen as anthropomorphic.

The paper treats the challenges and transformations of the Buddhist community in China on its way to the present state, both in national and international terms. The research focuses upon the dynamics of the relationship between the state and religion in China – from the demise of the empire to the present, with special emphasis upon the period of the People’s Republic of China. This review of the relevant literature concentrates upon the anthropological paradigms treating the relationship between state and religion, as well as upon state, political and religious institutions – national, provincial, municipal. Two concrete examples are presented of the renowned Buddhist monasteries – Nanputuo and Shaolin. Special attention is paid to the Buddhist Association of China and its role in the negotiation between the state and party organizations and Buddhist monasteries.
Technology Studies and Material Culture Studies: Possibilities of Cooperation in the Case of Bone Artefacts
Authors: Vitezović Selena , Vranić Ivan
Published: November 2017

Bone artefacts are among the less thoroughly studied classes of archaeological material, especially in the case of particular periods and regions. The reasons behind this are not uniform. The most obvious and general are linked to the research practices of culture-historical archaeology, often neglecting bone artefacts, considering them not sufficiently attractive or informative. The most significant shift towards recognition of a set of potential information gained from bone objects was achieved in the framework of studies of prehistoric technology during the second half of 20th century, especially in the French archaeological school.  This research strategy raised a number of questions concerning the acquisition of raw material, modes of production and usage of objects, whose interpretative potential gained in power, leading to the increased attention paid to faunal remains in archaeological investigations. Yet this source of information on the actual details of relations between people and material culture, opened by technology studies, has not been sufficiently explored.  It may be suggested that the reasons are the narrow specialization of researchers and insufficient inclusion of the gathered information into the wider interpretive framework, various traditions and lack of cooperation among the national archaeological “schools”, language barriers etc. However, the main reason behind this state of affairs may be sought for in non-integrated theoretical perspectives and the lack of clearly articulated interpretive position of researchers seeking to apply the knowledge gained from technology studies, considering this strategy as an “objective, scientific method”, providing concrete answers clearly complying to the expectations of the dominant archaeological paradigm.

The paper offers a critical review of a number of examples of application of technology studies in archaeology and possible directions of a more integrated and theoretically informed approach. One of the obvious solutions may be sought in the direction of another research strategy – material culture studies. The aim of the paper is thus to link these two approaches, whose theoretical foundations are not uniform today, but the history of the ideas and the mode of articulation of the basic theoretical assumptions indicate similar theoretical roots.
Discontinuity of Funerary Rites in Late Praehistory of the Central Balkans
Authors: Kuzmanović Zorica
Published: November 2017

Starting from the fact that the present knowledge of the late praehistory of the Central Balkans is based almost exclusively upon interpretations of funerary remains, the aim of this paper is to investigate the theoretical premises of the archaeological research into burials in this region. Problems and limitations of the traditional culture-historical approach to funerary practices are discussed, and the second part of the paper aims to demonstrate that the shift in theoretical perspective may result in fundamentally different insights into the explanatory potential of funerary rites in archaeology.
Landscape Archaeology of the Late La Tène in South Pannonia: Perspectives and Possibilities of Stable Isotope Analyses
Authors: Radišić Teodora
Published: November 2017

In the long tradition of research into the La Tene period in the region of South Pannonia many questions have been raised, but economic activity, especially agriculture and cattle-breeding, have not received due attention. The existing archaeological data permit the hypothesis that both settlement and agriculture intensified during this period, and these activities may have induced changes in the landscape. However, apart from sporadic comments, this topic has not been the object of research. The development of landscape archaeology and stable isotope analyses have made possible a better understanding of the ways people moved through landscape, used and changed it. It should be borne in mind that landscapes are not only spaces out of which humans derive resources in the most rational way, but also a product, medium, and a reflexion of various individual and collective experiences on social, symbolic and historical levels. The paper discusses the possibilities and perspectives of application of stable isotope analyses of carbon and strontium in animal bones retrieved from the late La Tene settlements in South Pannonia, with the aim of verifying the existing hypotheses and formulating new ones concerning economic practices and socio-political circumstances.
Antiquarians between Nature and Culture
Authors: V. Мihајlоvić Vlаdimir
Published: November 2017

From the second half of the 16th century to the beginning of the 18th century, the foundations of modern science were laid through the wide-ranging changes in comprehension of both nature and European societies, today labeled as “scientific revolution”. By the end of this period in the history of European science, the interpretation of universe did not necessarily include the divine intervention and, along with the objectification of nature, the past was objectified as well.

The approaches articulated during the scientific revolution were applied to the investigation into the human past in the works of the antiquarians. The new ways of observation, description, and collection of antiquities were generated as a part of the wider interests in natural history. On the other hand, it may be argued that the antiquarians’ practice joined together the approaches we would today judge as opposed: the ones derived from social theory , as well as the ones based upon natural sciences. In their studies of the past, the antiquarians equally used written sources as well as “naturalistic” methods, such as careful observation, establishment of classifications, or experimental design.

Taking into account the significant contribution of antiquarians to the establishment of disciplinary foundations of archaeology, the paper aims to point to some new possibilities of approaching the study of the past, primarily beyond the established dichotomy of artifacts/ecofacts, and to offer the ways of bridging the present divisions inside the discipline.
Mummy – Body, Antiquity, or Medicine?
Authors: Vasiljević Vera , Babić Staša
Published: November 2017

In the Renaissance Europe, along with the keen admiration for Egyptian antiquities, a custom has been recorded of production and consumption of a powder healing a number of ailments, produced by grating mummies. The practice extended into the 20th century. The belief in the remedial effects of this substance is derived from the Classical and Arabic written sources, and may have been augmented by the ideas about the mystical wisdom of the ancient Egyptians, running throughout the European history and originating among the Classical Greeks. This exceptional example raises the problem of various ways in which the material remains of the past are perceived and classified. In the case of an Egyptian mummy, the object is a human body prepared for Afterlife in a culturally specific manner. Reception of ancient Egypt in subsequent epochs shrouded the practice of mummification, along with other aspects of this culture, in the veil covering the original character of the materialized trace. A human body – ecofact, subjected to a ritualized treatment, thus became an antiquity – artefact, whose possession insured social prestige. At the same time, precisely because its cultural affiliation, it was perceived as a source of healing powers, in the same way as some natural substances derived from plants or animals. The case of the Egyptian mummy illustrates the porosity of demarcation lines between the material traces of the past categorised as natural/cultural, artefact/ecofact, further leading to specialized and insufficiently integrated archaeological interpretations.
The Introduction of Mapping Cultures in European Archaeology - Time Meets Space
Authors: Bandović Aleksandar
Published: November 2017

Prehistoric archaeology derives its roots from various practices and sciences: antiquarianism, natural history, geology, philology etc. The key conceptual tools of archaeology, including its “basic bloc” – archaeological culture, were formed by the end of the 19th century. Identifying the spatial dimension of archaeological cultures is largely linked to the innovations in adjacent disciplines, such as anthropogeography and its founder Friedrich Ratzel, but also with the general developments in cartography, perceived as a useful and “objective” tool for mapping the European nation states and various ethnic and linguistic communities. Ratzel based his ideas upon the ones of Moritz Wagner, geographer, traveller and researcher, and his work Law of the Migration of Organisms, conceived as an extension   to Darwin’s theory of evolution. The innovative method of mapping cultures, as well as migrationism, have both remained permanent traits of Ratzel’s anthropogeography and the school of “cultural circles”. The examples from German-speaking archaeology demonstrate beyond doubt the ways in which the visualisation of archaeological cultures influenced the interpretations of European prehistory.
Abuse of Natural Sciences in (Pseudo)Archaeology
Authors: Milosavljević Monika , Palavestra Aleksandar
Published: November 2017

In pseudo-archaeological writings, both the ones originating from marginal sources, but as well from the grey zone inside the discipline itself, a tendency can be identified to invoke various analyses and methods from the realm of natural sciences, aimed at justifying authors’ ideas. The aim of this strategy is dislocation of argumentation from the field of archaeology and verifiable archaeological data into the more slippery field of false complexity and presumed interdisciplinarity. Archaeological epistemology presupposes that every interpretation of the past requires a clear and explicit theoretical framework and verifiable data, as well as their dynamic relationship of reciprocity through research design. On the other hand, as a rule pseudo-scientific claims do not comply to any theoretical or methodological framework, and the very data base used spans from simple forgeries to random interpretations of authentic artefacts. In order to compensate for weak or even non-existent archaeological grounds of these interpretations, argumentation is transferred into the area supposed to be less accessible to archaeological public, so that false and unsubstantiated claims can be made.

Los estudiantes de Psicología a distancia tienen actualmente la necesidad de contar con una formación profesional que les garantice mayor eficiencia y competencia para incidir en la solución de problemas de salud emocional. En ese sentido, el objetivo principal de esta investigación fue conocer la eficacia de un programa de práctica supervisada y mediada por tecnología, para garantizar el desarrollo de competencias clínicas en los estudiantes de psicología a distancia. El programa de formación tuvo una duración de cinco meses y se basó en un modelo de competencias profesionales. Se implementó un estudio piloto con diez estudiantes de los últimos semestres de la licenciatura en Psicología. Los datos obtenidos mediante la administración de la Escala de terapia cognitiva (ETC), de Beck y Young (1980), evidenciaron que los practicantes mejoraron sus habilidades clínicas después de terminar el programa de entrenamiento. Asimismo, los resultados de la prueba estadística no paramétrica rangos de Wilcoxon, se obtuvieron diferencias significativas entre las evaluaciones anterior y posterior al entrenamiento (z = 2,20; p = ,027). En cuanto a la satisfacción de los participantes con el programa de formación, los estudiantes consideraron que es un escenario de formación innovador para el desarrollo de sus habilidades clínicas. Es así que resulta pertinente proponer una alternativa prometedora ante la carencia de escenarios de práctica profesional y, de ese modo, lograr que los estudiantes se involucren en escenarios reales vinculados a sus intereses o a la propia estructura curricular.

Se desarrolló un Ambiente Virtual de Aprendizaje (AVA) para la capacitación tipo Inducción a los colaboradores ICBF, mediante contenidos estratégicos y misionales a través de la implementación de diferentes herramientas multimedia para la apropiación de conocimientos que anteriormente sólo setransmitían de forma presencial en las diferentes regionales del ICBF. El diseño de un AVA mediante espacios Web 2.0 involucró la participación de colaboradores del Instituto. Estos espacios permitieron escenarios colaborativos para gestionar conocimiento e información relevante hacia la capacitación de procesos donde se involucran poblaciones vulnerables de niños, niñas y adolescentes, reduciendo de manera significativa la inversión de recursos económicos logísticos en desplazamiento, capital humano y tiempos invertidos en capacitaciones en sitios presenciales. Asimismo, el AVA, como instrumento para la capacitación tipo inducción, aportó ampliamente al fortalecimiento del desempeño y competencias de los colaboradores ICBF como entidad pública, desde un modelo cooperativo.

Authors: Rojas Salgado Milagros Esperanza
Published: November 2017

En este artículo se presenta un estudio etnográfico de la situación actual de la enseñanza de las ciencias naturales en nuestro país, desde la perspectiva de los lineamientos educativos a nivel nacional. Asimismo, se sustenta la necesidad de la integración de los recursos tecnológicos en esta área. El objetivo fue documentar las formas en las que se podría innovar teniendo en cuenta que las Tecnologías de la Información y la Comunicación (TIC) son un medio para alcanzar los resultados de aprendizajes planteados y no un fin en sí mismo, pues permiten aprovechar las competencias que nuestros estudiantes están desarrollando en su día a día para lograr y/o empoderar sus aprendizajes. A partir del estudio se puede concluir que la integración de las TIC en la enseñanza de las Ciencias Naturales es necesaria y pertinente, dado que contribuyen al logro de los resultados de aprendizaje esperados en los estudiantes, generando competencias no solo a nivel cognitivo sino también a nivel actitudinal.
CONCEPCIONES DE LA ÉTICA Y LA FILOSOFÍA CLÁSICA GRECOROMANA
Authors: Vasquez Cerna Oswaldo
Published: November 2017

La filosofía, como creación humana a través de su evolución histórica, se plasma como instrucción, con la filosofía clásica greco romana,  del  siglo VII a.de C. al siglo V d. de C, a la que se trata de hermanar nuevamente con la ciencia, la cual resulta positivo. Después de la Segunda Guerra Mundial, la filosofía fue dejada de lado en el proceso de vinculación entre la ciencia y la tecnología. Durante casi toda la segunda mitad del siglo XX, la ciencia y la tecnología, ejercieron una influencia notable, permitiendo incluso que se efectuaran críticas severas a la filosofía en el sentido de que era anacrónico hablar de reflexiones filosóficas en plena era científico-técnica. El presente trabajo es un relato histórico de la vinculación entre filosofía y ética, enfocado desde la época grecorromana, por tanto el artículo es un enfoque de la aplicación de la ética y la deontología a las ciencias contables y, al mismo tiempo, a los negocios.

RESUMEN Considerando la importancia creciente que está teniendo la apreciación de la empresa basada en los recursos, los procesos, la perspectiva del conocimiento, el aprendizaje organizativo y la búsqueda de la eficacia/eficiencia, nos ha motivado a ver la relación existente entre la integración de recursos con los logros eficaces/eficientes, a los que siempre los hemos visto vinculados o interdependientes, aunque cuenten con poco análisis e investigación. Ahora sabemos,  que los recursos: •  Permiten la producción empresarial y cuando se les relaciona con el producto, comprueban la productividad. •     Nutren las organizaciones e impiden. •          Comprometen la mayoría del capital social, impactando la liquidez empresarial. También reconocemos que las performances eficaces/eficientes son las más intensamente buscadas por los empresarios modernos, por lo que debemos acopiar y facilitar respuestas para esas inquietudes, echando mano de la perspectiva empresarial y de los aprendizajes logrados en nuestra formación profesional. La eficacia/eficiencia solo será lograda si los recursos que se deben integrar a la empresa son los que se requieren para la producción, según las especificaciones que se tengan de ellos. De la misma manera que los productos obtenidos serán los que los clientes prefieran. Y este es el alineamiento que tiene que lograrse en el quehacer empresarial.  ABSTRACT Considering the growing importance that is having the appreciation of the company based on the resources, processes, the perspective of knowledge, organizational learning and the pursuit of effectiveness/efficiency we have been motivated studying the existent relationship between the integration of resources and the effective/efficient achievements. Now we know that the resources: •          allow the business production and when they are related to the product, they check out the productivity. •          Maintain the organizations and prevent the anomie. •          compromise the majority of the share capital, impacting the business liquidity We also recognize that the effective/efficiency performances are the most intensely sought after by modern companies, that’s why we must collect and provide answers to these concerns, making use of the business perspective and the learning achieved in our training. The effectiveness / efficiency will only be achieved whether resources which must be integrated to the company are required to produce, In the same way that the products obtained will be the ones those customers prefer. Such an alignment is essential on the everyday business work.
