Jóvenes en Bachilleratos Populares: entre la individuación y la subjetivación política
Authors: Said Shirly
Published: March 2018

In this article we seek to relate the concept of political subjectivation with the contributions of the sociologies of the individual, looking forward to generating theoretical and methodological tools that enrich a located analysis of young people ?s experiences in Popular High Schools in Argentina. Our main hypothesis is that there is a distance between the students’ initial expectations and these schools’ institutional proposal, that can be expressed as a latent tension between individuation and subjectivation processes. It questions how to study youngsters ? individuation processes, in which the scholar trial is crucial, without disattending the political subjectivation processes presented as possible. In methodological terms, it inquires how to approach young people ?s experiences with an attitude of epistemological surveillance, and reflects on the potentialities of the biographic approach. It concludes that this perspectiwve can provide with suitable theoretic-methodological tools for the objectives of this research, giving priority to the production of life stories.
Los imaginarios matacanes del castillo de Cornatel en El Señor de Bembibre de Gil y Carrasco. Estudio lexicográfico en torno a los términos matacán, matacaspas y sa[b]ratana
Authors: Ares Ares María Álida
Published: March 2018

En este artículo hemos estudiado el término matacaspas que aparece en el cap. 26 de la obra de Enrique Gil y Carrasco El Señor de Bembibre (1844) y que ha suscitado comprensibles dudas en los editores de la obra, siendo enmendado con frecuencia por matacanes. Nuestro objetivo era averiguar la propiedad del uso de la voz y para ello hemos estudiado el contexto y acudido a sus fuentes literarias y hemos recogido documentación lexicográfica acerca del uso del término en la literatura especializada, en base a lo cual podemos afirmar que la aparición en la obra de Gil y Carrasco de la voz estaría legitimada. Asimismo hemos querido arrojar luz sobre el origen, la etimología, las variantes y acepciones que han cobrado diversas voces relacionadas con el término matacán.

Published: March 2018

In data processing time series of meteorological data problems, you are incomplete in some time intervals; it addresses the issue commonly using the autoregressive integrated moving average (ARIMA) or the method by regression analysis (interpolation), both with certain limitations under particular conditions. This paper presents the results of an investigation aimed at solving the problem using neural networks reported. The analysis of a time series of global radiation obtained at the Francisco de Paula Santander University (UFPS) is presented, with basis in the recorded data by the weather station attached to the Department of Fluids and Thermals. Having a series of ten-year study for 125,658 records of temperature, radiation and energy with a percentage of 9.98 missing data, which were duly cleared and completed by a neural network using algorithms backpropagation in the mathematical software MATLAB
A model of multilayer tiered architecture for big data
Authors: Ordóñez Salinas Sonia , Nieto Lemus Alba Consuelo
Published: March 2018

Until recently, the issue of analytical data was related to Data Warehouse, but due to the necessity of analyzing new types of unstructured data, both repetitive and non-repetitive, Big Data arises. Although this subject has been widely studied, there is not available a reference architecture for Big Data systems involved with the processing of large volumes of raw data, aggregated and non-aggregated. There are not complete proposals for managing the lifecycle of data or standardized terminology, even less a methodology supporting the design and development of that architecture. There are architectures in small-scale, industrial and product-oriented, which limit their scope to solutions for a company or group of companies, focused on technology but omitting the functionality. This paper explores the requirements for the formulation of an architectural model that supports the analysis and management of data: structured, repetitive and non-repetitive unstructured; there are some architectural proposals –industrial or technological type– to propose a logical model of multi-layered tiered architecture, which aims to respond to the requirements covering both Data Warehouse and Big Data.
3D reconstruction system for semi-automatic estimation of objects length and area by means of stereo vision
Authors: García Bryan , Ferrin B. Carlos Diego , Erazo Jorge Humberto
Published: March 2018

It is mandatory to characterize dimensionally the manufactured industrial pieces for quality control purposes. As it is not possible to touch some pieces when trying to retrieve dimensional information, then non-invasive techniques are required to do so. Stereo vision is a passive technology which is both robust and accurate for non-invasive applications. For this reason, in this work we describe the design and implementation of a 3D reconstruction system for the estimation of the length and area of certain objects. This tool allows to easily incorporate new image correspondence techniques to its main execution pipeline. We carry some experiments and show certain benefits when selecting an accurate image correspondence technique for the estimation of the length and area.
Review of accessibility and usability guidelines for website design for the elderly people
Authors: Aguirre Diego Fernando , Abadía Iván
Published: March 2018

By 2050, the growth of the elderly population in Colombia is estimated at 10% and thus a greater demand for special services (such as health services) for the elderly. This justifies the exploration of digital health content as an important source of information for this population. The accessibility and usability guidelines for website design –e.g., TAW and WACG– do not have specific guidelines to mitigate the motor, cognitive or visual disabilities characteristic of aging, which become a barrier for this group to consult necessary information for administrative processes that involve health. This review of accessibility and usability guidelines is presented, facilitating the consumption of specific contents and generating better interactions with such systems, which will lead to the construction of guidelines based on existing recommendations that allow the development of aspects related to interaction, legibility and usability in digital content for the elderly.

Authors: Villalba Montagut Wilfred , Villamizar Carrillo Laura Patricia , Sánchez Delgado Maritza del Pilar
Published: March 2018

This paper provides a consultation tool for implementation of teleworking in software development organizations. This concept was born for using highly experienced human talent with specific knowledge and skills, in activities that contribute to the development of technological projects within organizations dedicated to development of software, without its physical presence being necessary, as is the case of the Center for Applied Research in Development and Information Technologies [CIADTI] of the Universidad de Pamplona (Colombia). A model that results from the investigation is exposed, which was applied and validated, with an acceptance higher than 79%, so its implementation can be considered in other organizations.

Authors: Serra Flavia , Delgado Tatiana
Published: March 2018

Multidimensional models and their measures regarding different dimensions are powerful instruments for decision makers. An ontology, in its basic expression as RDF, represents the reality from relationships between classes, and it is the base for linked data of the semantic Web. This work provides a basic methodology to obtain an ontology RDF from a multidimensional model of a data warehouse, capable to be aligned to other ontology of the Sustainable Developments Goals. Specifically, an approaching of alignment with the Sustainable Development Goals Interface Ontology [SDGIO] emerging by the United Nations Environmental Program [UNEP] is included. This methodology labeled as DW2RDF4SDG is instrumented for the SDG 6, aimed to ensure availability and sustainable management of water and sanitation for all.

Authors: Castillo Rodríguez Diony Roely , Martínez Laguardia Alain Sebastián , Gómez Abreu Alberto
Published: March 2018

The usage of real-time tracking systems for vehicles has demonstrated to be a viable and economical option, entailing in more control and management of the fleet, plus the reduction of the logistics costs of companies using them. Since 2006 in Cuba, there is a fleet control and management system employed by almost all the companies, which hire a variant of the service in a differed manner; i.e., the data are not processed in real-time. In this research paper, we propose the design of a device based only on open source hardware/software components allowing the real-time vehicle tracking. Our proposal is suitable for the conditions of the country where it was developed (Cuba), presenting high functionality than other proposals. For the design, we employed an Arduino UNO controller board, an Adafruit FONA808 GPS/GSM module, and other accessories. As per the performed experiments, the proposed hardware/software architecture complies with the operation, configuration, and security requirements to achieve a viable product from the economical and environmental approaches.

Published: March 2018

The aim of this study was to assess regional perfusion at baseline and regional cerebrovascular resistance (CVR) to delayed acetazolamide challenge in subjects with chronic carotid artery stenosis.Sixteen patients (ten males) aged 70.94±7.71 with carotid artery stenosis ≥90% on the ipsilateral side and ≤50% on the contralateral side were enrolled into the study. In all patients, two computed tomography perfusion examinations were carried out; the first was performed before acetazolamide administration and the second 60 minutes after injection.The differences between mean values were examined by paired two-sample t-test and alternative nonparametric Wilcoxon’s test. Normality assumption was examined using W Shapiro-Wilk test.The lowest resting-state cerebral blood flow (CBF) was observed in white matter (ipsilateral side: 18.4±6.2; contralateral side: 19.3±6.6) and brainstem (ipsilateral side: 27.8±8.5;  contralateral side: 29.1±10.8). Grey matter (cerebral cortex) resting state CBF was below the normal value for subjects of this age: frontal lobe – ipsilateral side: 30.4±7.0, contralateral side: 33.7±7.1; parietal lobe – ipsilateral side: 36.4±11.3, contralateral side: 42.7±9.9; temporal lobe – ipsilateral side: 32.5±8.6, contralateral side: 39.4±10.8; occipital lobe – ipsilateral side: 24.0±6.0, contralateral side: 26.4±6.6). The highest resting state CBF was observed in the insula (ipsilateral side: 49.2±17.4; contralateral side: 55.3±18.4). A relatively high resting state CBF was also recorded in the thalamus (ipsilateral side: 39.7±16.9; contralateral side: 41.7±14.1) and cerebellum (ipsilateral side: 41.4±12.2; contralateral side: 38.1±11.3). The highest CVR was observed in temporal lobe cortex (ipsilateral side: +27.1%; contralateral side: +26.1%) and cerebellum (ipsilateral side: +27.0%; contralateral side: +34.6%). The lowest CVR was recorded in brain stem (ipsilateral side: +20.2%; contralateral side: +22.2%) and white matter (ipsilateral side: +18.1%; contralateral side: +18.3%). All CBF values were provided in milliliters of blood per minute per 100 g of brain tissue [ml/100g/min]. Resting state circulation in subjects with carotid artery stenosis is low in all analysed structures with the exception of insula and cerebellum. Acetazolamide challenge yields relatively uniform response in both hemispheres in the investigated population.Grey matter is more reactive to acetazolamide challenge than white matter or brainstem.

Las interacciones didácticas en el marco de las prácticas educativas en la videoconferencia
Authors: Armellini Alejandro , Gregori Mirian , Núñez Coronel Lely , Sosa Amadeo
Published: March 2018

En el último siglo los avances científicos y tecnológicos fueron objeto de una mayor rapidez de cambio que en los siglos anteriores. Esto tiene su repercusión en lo económico, social, educativo, así como en tantas otras áreas, planteando la necesidad de una formación ciudadana básica que le permita a los individuos reconocer e interpretar los cambios que se están produciendo a su alrededor. Esto exige de los docentes una formación permanente y de sus alumnos, la necesidad de aprender a seleccionar, jerarquizar y utilizar la información que reciben a través de los nuevos medios tecnológicos. Por otra parte, es necesario superar la distancia para lograr una actualización continua de los conocimientos de los profesionales, particularmente en regiones distantes de los centros principales de actividad educativa, como en el interior de Uruguay, donde es difícil acceder a la capacitación buscada.

Trabajo en equipo: de la teoría a la cultura institucional
Authors: Pintos Artigas María Ema , Martínez Sagasta Fernando
Published: March 2018

Quienes realizamos este estudio, Coordinadores Adscriptos en el área de 5º y 6º año de bachillerato de una institución educativa privada, trabajamos desde hace veinte años en la formación, seguimiento y acompañamiento personal y grupal de sus estudiantes. Nuestras experiencias en el ámbito de la misma, nos permite percibir que los distintos educadores que integramos los diferentes campos disciplinares, cuando nos reunimos para trabajar en equipo, en reiteradas oportunidades lo hacemos en grupos separados, especialmente con relación a nuestras disciplinas, o, adoptando formas limitadas, en el sentido de que los educadores no ejercemos la enseñanza conjunta dentro del aula. Se trata de un trabajo en equipo que se concentra en lo inmediato, en el corto plazo y excluye los problemas de planificación del plazo más largo, o de una forma impuesta o más dirigible, que es buena para cuando se inicia en la modalidad de trabajo en equipo, pero que no es deseable se extienda en el tiempo, -lo que constatamos ocurre en ocasiones-. Frente a estas percepciones deseamos indagar cómo estamos interactuando los educadores en los diferentes equipos de trabajo.Consideramos al trabajo en equipo como enriquecedor de los procesos educativos y le otorgamos gran importancia a su proyección en el tiempo, por esto pensamos que nuestro aporte puede colaborar en que se llegue a esta toma de conciencia, e ir poco a poco, transformando la teorización del tema en una verdadera cultura de trabajo en equipo. Nuestro propósito, pues, es indagar si el trabajo en equipo es favorecido o no, por la interacción entre los educadores. Para orientar nuestro estudio nos planteamos la siguiente interrogante: ¿la interacción entre los educadores favorece o no, el trabajo en equipo en 5º y 6º año de bachillerato de la institución en que trabajamos? Abordando aspectos que surgen de esta pregunta y que sirven como aproximación, la desagregamos en: ¿quién determina los equipos?, ¿para qué funcionan?, ¿cómo están funcionando?, ¿qué tipo de equipos trabajan?, ¿qué logros alcanzan estos equipos?

Este octavo número de los Cuadernos de Investigación Educativa recoge las cinco ponencias presentadas con motivo del III Ateneo "La gestión educativa ante los procesos de cambio: del discurso a las prácticas cotidianas", organizado por el Instituto de Educación de nuestra Universidad, el pasado 4 de junio de 2001.Estos cinco artículos trabajan sobre diferentes aspectos de la gestión educativa, pero todos ellos tienen algo en común: las miradas y reflexiones se han realizado desde marcos teóricos compartidos o complementarios. Los artículos recorren tópicos áulicos, institucionales y comunitarios. Eso permite, y facilita a la vez, comprender que la gestión educativa solicita un análisis multidimensional y multirreferencial. Los trabajos publicados cooperan con esa comprensión.

This chapter reviews how recent research can be applied in the development of new technologies and procedures to ensure a high level of welfare for pigs, while also increasing production efficiency, product quality and operator working conditions. Areas addressed include electrical and CO2 stunning methods, correct sticking procedure, group-based handling and the surveillance and documentation of animal welfare levels on the day of slaughter.
Comparative analysis of ceramic flexural strength in co-cr and ni-cr alloys joined by TIG welding and conventional brazing
Authors: Matos Adaias Oliveira , Branco Cristiane de Castro Castelo , Klautau Eliza Burlamaqui , Alves Bruno Pereira
Published: March 2018

The purpose of the present study was to evaluate the flexural strength of specimens made of nickel-chromium (Ni-Cr) and cobalt-chromium (Co-Cr) alloys and joined by tungsten inert gas (TIG) welding and conventional brazing. Ni–Cr and Co–Cr base metal specimens (n = 40, each) were cast and welded by TIG or brazing. The specimens were divided into six groups (2 base metals, four welded specimens). Ceramic systems were applied to the central part of all the specimens. A three-point bending test with a velocity of 0.5 mm/m was performed on the specimens up to the point of the first ceramic bond failure by measuring the flexural strength. Data were analyzed using two-way ANOVA and Bonferroni’s tests. Conventional welding showed the lowest flexural strength results for both alloys, while the TIG weld and the control group presented with varying bond strengths for the alloys studied. We concluded that TIG welding was superior to the conventional welding method for both Ni–Cr and Co–Cr alloys with regard to the flexural strength of the ceramic.

Published: March 2018

Objective: this study aimed to assess the effect of treatment of phosphoric acid etched dentin surface with 5% bromelain enzyme and Nd:YAG laser prior to the use of etch and rinse adhesive systems on microleakage margins of class V composite restorations. Materials and Methods: sixty sound premolar teeth were selected. Standard class V cavities were prepared in the buccal and lingual surfaces of each teeth. Preparation in that way 1 mm of the cavity was above and 1 mm of it was below the cementoenamel junction. The teeth were then randomly divided into three groups including 20 teeth(40cavities  in each gorup). Two ethanol base etch and rinse system (Adper Single Bond and OptiBond Solo) was applied in each group. In the control group, cavities were etched with 37% phosphoric acid. Adper Single Bond was applied to 20 and OptiBond Solo was applied to the remaining 20 cavities and they were restored with Z250 composite (n=40). The same procedures were performed in bromelain and Nd:YAG laser groups with the difference that prior to the application of adhesive, aqueous 5% bromelain was applied in bromelain group while Nd:YAG laser was irradiated in laser group. All teeth were thermocycled and their apices were sealed with sticky wax. The tooth surfaces were coated with nail varnish except for 1 mm around the restoration margins, and the teeth were then immersed in fuchsine and sectioned by a diamond disc into mesial and distal halves. Marginal microleakage at both sides was determined and scored under a stereomicroscope at x40 magnification. Then data were analyzed using the Kruskal Wallis and Mann Whitney tests (α=0.05). Results: according the result of Mann Whitney test, Cervical margins showed significantly higher microleakage than the occlusal margins (P=0.000) but no significant difference was noted in microleakage of occlusal (P=0.362) or gingival (P=0.147) margins among the three groups by Kruskal Wallis test. Conclusion: in conclusion, application of proteolytic agents(5% bromelain solution and Nd:YAG laser)  on acid-etched dentin surface prior to the application of adhesive has no significant effect on marginal microleakage of class V composite restorations.
Alterações nas estratégias de subsistência: o caso dos índios brasileiros Xavantes
Authors: Silva Rafael José Navas da , Garavello Maria Elisa de Paula Eduardo
Published: March 2018

O objetivo deste trabalho foi analisar as transformações ocorridas na alimentação da comunidade indígena xavante, da aldeia Wede´rã, no Estado de Mato Grosso, Brasil, com a introdução da agricultura mecanizada. Foi utilizado o enfoque qualitativo, com técnicas de entrevista e observação participante. Verificou-se que, com a introdução da mecanização na produção agrícola e o processo de sedentarização, o arroz tornou-se base da alimentação, substituindo outros alimentos tradicionalmente consumidos, obtidos principalmente através da coleta. A utilização da caça ainda permanece, entretanto, com maior impacto ambiental. Outras alterações na dieta são a compra de alimentos industrializados e a composição das refeições do Programa Nacional de Alimentação Escolar – PNAE, popularmente conhecido como merenda escolar. Tais transformações podem estar associadas à causa de 56,3% de prevalência de anemia entre a população da aldeia, constatada em 2006. Há esforços para alterar esse quadro, mas, mudanças no modo de vida e organização social dos indivíduos e nas relações destes com a natureza, podem estar comprometendo a sua segurança alimentar e nutricional de modo irreversível.

Facile Syntheses and Molecular-Docking of Novel Substituted 3,4-Dimethyl-1H-pyrrole-2-carboxamide/carbohydrazide Analogues with Antimicrobial and Antifungal Properties
Authors: Bhosale Jitendra D. , Dabur Rajesh , Jadhav Gopal P. , Bendre R. S.
Published: March 2018

The article describes facile one-pot, hi-yielding reactions to synthesize substituted 3,4-dimethyl-1H-pyrrole-2-carboxamide (3a–m) and carbohydrazide analogues (5a–l) as potential antifungal and antimicrobial agents. The structural integrity and purity of the synthesized compounds were assigned based on appropriate spectroscopic techniques. Synthesized compounds were assessed in vitro for antifungal and antibacterial activity. The compound 5h, 5i and 5j were found to be the most potent against A. fumigatus, with MIC value of 0.031 mg/mL. The compound 5f bearing a 2,6-dichloro group on the phenyl ring was found to be the most active broad spectrum antibacterial agent with MIC value of 0.039 mg/mL. The mode of action of the most promising antifungal compounds (one representative from each series; 3j and 5h) was established by their molecular docking to the active site of sterol 14α-demethylase. Molecular docking studies revealed a highly spontaneous binding ability of the tested compounds in the access channel away from catalytic heme iron of the enzyme, which suggested that the tested compounds inhibit this enzyme and would avoid heme iron related deleterious side effects observed with existing antifungal compounds.
Travel Time Prediction Based on Data Feature Selection and Data Clustering Methods
Authors: Chen Chi-Hua
Published: March 2018

In recent years, governments applied intelligent transportation system (ITS) technique to provide several convenience services (e.g., garbage truck app) for residents. This study proposes a garbage truck fleet management system (GTFMS) and data feature selection and data clustering methods for travel time prediction. A GTFMS includes mobile devices (MD), on-board units, fleet management server, and data analysis server (DAS). When user uses MD to request the arrival time of garbage truck, DAS can perform the procedure of data feature selection and data clustering methods to analyses travel time of garbage truck. The proposed methods can cluster the records of travel time and reduce variation for the improvement of travel time prediction. After predicting travel time and arrival time, the predicted information can be sent to user’s MD. In experimental environment, the results showed that the accuracies of previous method and proposed method are 16.73% and 85.97%, respectively. Therefore, the proposed data feature selection and data clustering methods can be used to predict stop-to-stop travel time of garbage truck.

Published: March 2018

Fruits of chayote [Sechium edule (Jacq.) Swartz] are widely consumed in Mesoamerica, but little is known about the nutraceutical potential. This study aimed to determine the chemical compositions, antioxidant activities from the juice fruits from two commercial varieties of chayote cultivated in Mexico, as well as a proposal for the elaboration of chayote juices with stevia leaves and pineapple juice. The physicochemical properties of juice from virens levis (VL) and nigrum spinosum (NS) varieties were determined using standard methods. The juice of the two varieties differ significantly regarding the concentrations of total soluble solids, total sugars, but not vitamin C. The total concentration of phenolics in NS extracts was slightly higher than in VL (1005 and 856 mg 100 g−1 dry-weight, respectively) but the total flavonoid contents were similar (27 and 26 mg 100 g−1 dry-weight, respectively). Cucurbitacin D was predominant in both varieties. The radical scavenging capacities of VL and NS extracts varied slightly (IC50 = 0.45 to 0.65 mg mL−1), while the antioxidant activities were similar (~80%). The NS variety is particularly promising regarding nutraceutical application. The chayote juice combined with stevia and pineapple maintain the original nutraceutical characteristics from the fruit, but enhanced the organoleptic characteristics like density and sugar/acidity balance.
The Western Diet–Microbiome-Host Interaction and Its Role in Metabolic Disease
Authors: Zinöcker Marit K. , Lindseth Inge A.
Published: March 2018

The dietary pattern that characterizes the Western diet is strongly associated with obesity and related metabolic diseases, but biological mechanisms supporting these associations remain largely unknown. We argue that the Western diet is promoting inflammation that arises from both structural and behavioral changes in the resident microbiome. The environment created in the gut by ultra-processed foods, a hallmark of the Western diet, is an evolutionarily unique selection ground for microbes that can promote diverse forms of inflammatory disease. Recognizing the importance of the microbiome in the development of diet-related disease has implications for future research, public dietary advice as well as food production practices. Research into food patterns suggest that whole foods is a common denominator of diets associated with a low level of diet-related disease. Hence, by studying how ultra-processing changes properties of whole foods and how these foods affect the gut microbiome, more useful dietary guidelines can be made. Innovations in food production should be focusing on enabling health in the super-organism of man and microbe, and stronger regulation of potentially hazardous components of food products is warranted.
Projecting Drivers of Human Vulnerability under the Shared Socioeconomic Pathways
Authors: Rohat Guillaume
Published: March 2018

The Shared Socioeconomic Pathways (SSPs) are the new global development trends that inform global and regional climate change research. They have the potential to foster the integration of socioeconomic scenarios within assessments of future climate-related health impacts. To date, such assessments have primarily superimposed climate scenarios on current socioeconomic conditions only. Until now, the few assessments of future health risks that employed the SSPs have focused on future human exposure—i.e., mainly future population patterns—neglecting future human vulnerability. This paper first explores the research gaps—mainly linked to the paucity of available projections—that explain such a lack of consideration of human vulnerability under the SSPs. It then highlights the need for projections of socioeconomic variables covering the wide range of determinants of human vulnerability, available at relevant spatial and temporal scales, and accounting for local specificities through sectoral and regional extended versions of the global SSPs. Finally, this paper presents two innovative methods of obtaining and computing such socioeconomic projections under the SSPs—namely the scenario matching approach and an approach based on experts’ elicitation and correlation analyses—and applies them to the case of Europe. They offer a variety of possibilities for practical application, producing projections at sub-national level of various drivers of human vulnerability such as demographic and social characteristics, urbanization, state of the environment, infrastructure, health status, and living arrangements. Both the innovative approaches presented in this paper and existing methods—such as the spatial disaggregation of existing projections and the use of sectoral models—show great potential to enhance the availability of relevant projections of determinants of human vulnerability. Assessments of future climate-related health impacts should thus rely on these methods to account for future human vulnerability—under varying levels of socioeconomic development—and to explore its influence on future health risks under different degrees of climate change.

Authors: Suto Shota , Watanabe Toshiya , Shibusawa Susumu , Kamada Masaru
Published: March 2018

A tabletop system can facilitate multi-user collaboration in a variety of settings including small meetings, group work, and education and training exercises. The ability of identifying the users touching the table and their positions can promote collaborative work among participants, so methods have been studied that involve the attaching of sensors to the table or chairs or to the users themselves. An effective method of recognizing user actions without placing a burden on the user would be some type of visual process, so the development of a method that processes multi-touch gestures by visual means is desired. This paper describes the development of a multi-touch tabletop system using infrared image recognition for user position identification and presents the results of touch-gesture recognition experiments and a system usability evaluation. Using an FTIR touch panel and infrared light, this system picks up the shadow area of the user’s hand by infrared camera in relation to user touch operations and estimates user position by image recognition. The multi-touch gestures prepared for this system include an operation to change the direction of an object to face the user and a copy operation in which two users generate duplicates of an object. The average recognition rate of the change-direction gesture and copy gesture were found to be 96% and 85%, respectively. In addition, the system usability evaluation revealed that prior learning was easy and that system operations could be easily performed.

Malnutrition is still one of the big problems the majority of developing countries including Indonesia. Malnutrition is the result of insufficient intake of available nutrients in the human diet. The availability of nutrients is mainly determined by the output of food produced from agricultural systems. Plants provide almost all the necessary vitamins and minerals, but due to low mineral content in staple crops, resulting in the intake becomes less and lead to malnutrition or lack of nutrients. Unfortunately, as a result of population pressure, a lot of the current global food system does not provide enough micronutrients to ensure adequate micronutrient intake for everyone. This has resulted in an increase in the prevalence of micro-nutrient deficiencies (for example, iron deficiency, vitamin A deficiency, and iodine), which now afflicts many poor women resources, infants and children in developing countries. To get a balanced nutrition and adequate then improve the quality of agriculture as a food ingredient indispensable. Various attempts to overcome nutritional deficiencies especially regarding micro nutrient deficiencies, such as supplementation, food fortification and diversification of the food has a lot to do, but did not provide maximum results. Another alternative approach to address the problem of shortage of micronutrients is biofortification, genetic biofortification or agronomic biofortification. This approach emerged due to health and human well-being depends entirely on the plants, either directly or indirectly.

Rice is a staple food for society.Rice consumption in Indonesia is relatively high compared to ASEAN countries, which is 114 kg/year. The importance of rice for the society leads the government to provide rice in order to avoid food insecurity due to lack of food supply. To anticipate the increasing needs of food, the projection of rice consumption demand in the future is required. This research was a descriptive research using quantitative approach. The aim of this research was to obtain the prediction or projection of rice consumption demand in Yogyakarta Special Region. Data of rice consumption demand were collected from Department of Food Security and Counseling Agency of Yogyakarta. Data were analyzed using trend analysis by projecting past trends using regression analysis model. The trend analysis shows that rice consumption demand in Yogyakarta is increasing, therefore the strategy is required to fulfill rice supply in the future by prioritizing the production in food production centers.
