Authors: Kong Yanjun , Mei Yadong , Li Weinan , Yue Ben , Wang Xianxun
Published: October 2018

In this article, an enhanced water cycle algorithm (EWCA) is proposed and applied to optimize the operation of multireservoir systems. Three improvements have been made to the water cycle algorithm (WCA). They refer to high-quality initial solutions obtained by the chaos-based method, balancing of exploration of streams using a dynamic adaptive parameter, and dynamic variation of sub-water system size using the fitness value of rivers. For the purpose of verifying the improvements, three typical benchmark functions were selected as test functions. It has shown that EWCA performs better than WCA and water cycle algorithm with evaporation rate (ER-WCA). And then these three algorithms were also applied to optimize the operation of a multireservoir system with complex constrains as the case study. By comparing the results, it is found that the EWCA has higher ability to find a feasible solution in a narrow searching space. The effectiveness of the improvements is confirmed.

Published: October 2018

With the emerging vehicular network and the possible diverse applications, intelligent transportation systems (ITS) have been evolving to Cooperative ITS (C-ITS) with connected intelligent vehicles, and the topics in this field have raised more and more research interests recently. However, subjecting to the immaturity of V2X communication technology, the difficulty and high cost to deploy such large scale ITS with intelligent vehicles, emerging studies are stuck with the verification of these big C-ITS. As more and more expected, intelligent vehicles will play important roles in the future smart cities and societies, as diverse mobility carriers. Focusing on new features of these carriers, mainly covering cyber-physical fusion, vehicular networking, service-carrier and so on, one new ITS simulator QoS-CITS for such service-oriented C-ITS is designed and developed. To enhance the adaptability, a scenario reconfigurable architecture is firstly designed, in which scenes can be described via XML file. On this basis, the authors have implemented all reservation-based models of traffic objects, state-driven behaviors, cooperation mechanisms, and policies, which are proposed for service-oriented C-ITS. Through a series of experiments are conducted with different parameters and typical scenes, all simulation functions are efficiently verified. And finally, some important conclusions drawn from large amount of experiments via QoS-CITS are exhibited. It's important to note that, researchers can conduct various experiments, both the traditional Passing-Through-Intersection (PTI) problem and service-oriented cooperation, via setting parameters of QoS-CITS according to their requirements, and can also analyze the performance with statistics data recorded automatically.

Open Educational Resources in Teacher Preparation Programs
Authors: Baker Alesha D.
Published: October 2018

The purpose of this article is to examine whether the use of open educational resources (OER) in teacher preparation programs impacts the perception of the resource. P-12 schools are beginning to adopt OER; however, many teachers are unfamiliar with OER, which may slow diffusion throughout the institution. In this study, two groups of teacher candidates from two universities completed surveys evaluating their perceptions of OER. The first group used an open textbook in their course. The second group had no experience using OER. Results indicate that teacher candidates who used the open textbook perceived OER more positively and were more likely to want to use OER in their future classrooms. The results suggest that incorporating OER into courses during teacher preparation programs not only better prepares teacher candidates for using the resources after graduation, but also increases progression through the adoption process described in the diffusion of innovation theory.
Impact of Interactive Online TESOL Practicum Course on EL Teachers' Professional Growth
Authors: Song Kim H.
Published: October 2018

This mixed-methods study examined how an online practicum course could enhance teaching for English learners (ELs). Based on research on collaborative and nonjudgmental supervision, a guided online coaching model was adopted with technology-based tools such as Discussion Board, Kaltura, and VoiceThread. Three online coaching cycles were; preconference, observation of teaching videos, and post-conference. Posting frequency and exit-interview transcripts were data sources. There were two research questions: 1) What interactions occurred among online TESOL practicum course participants? and 2) What was the impact of the online TESOL practicum course on participants' EL teaching? The results showed that students interacted more among themselves than with the instructor. Three themes emerged from qualitative data analysis; acknowledgment, impact of cyclic coaching, and linguistically responsive EL-teaching. The results ensured students' active interaction at the virtual communal spaces with some challenges and enhancement of their EL-teaching due to cyclic online coaching.

Authors: Jo Y. , Choi J. , Park S. , Lee J. , Ki H. , Han S.
Published: October 2018

The activities related to exploitation for oil and gas in the Arctic areas increase significantly. In order to transport increased resources in the Arctic areas, large Arctic commercial vessels such as gas carriers, oil tankers, bulk carriers, etc. are needed for mass transportation. In Arctic area, the ice load is the main factor of environmental load acting on Arctic vessel. The ice load is increased with the enlargement of vessel.

The largest Arctic commercial vessel was built by DSME in 2016. The vessel was delivered after completion of ice trial in March 2017. The size of Arctic LNG carrier is larger than any other Arctic vessels have been constructed so far. The ice load monitoring system was installed for ice load measurement and structural safety of ice navigation of this large LNG carrier.

This paper is concerned with comparison between estimated ice load for structural design and measured ice load for vessel navigation in Arctic area. Design ice load was calculated according to prescriptive rules of the Classification societies. Actual ice load during ice navigation was measured from ice load monitoring system. The arrangement of sensors in the monitoring system was determined for the precise measurement of ice induced loads acting on the hull. FE analyses were also carried out to compare between estimated ice load and measured ice load considering complex structural details in the Arctic LNG carrier.
Application of Remote Sensing Imagery and Ancillary Products to Improve Safety and Logistical Efficiency of Arctic Operations
Authors: Carey Tiffany , Soofi Khalid A.
Published: October 2018

Remote Sensing Imagery and the derived ancillary products improved the efficiency and safety of upstream oil and gas operations on the North Slope of Alaska. These Arctic regions are remote, very difficult to access in general and sometimes only seasonably accessible. Our prudent and responsible Arctic Operations require regional-reconnaissance exploration, diligent monitoring of environment such as current state of vegetation, temporal changes of terrain, water drainage system and lakes. Finally, we also need very detailed logistical-planning of field operations. Remote sensing imagery and its derived ancillary products demonstrably improved all these aspects of our Arctic Operations.

For Arctic Operations, remote sensing data consisted of optical satellite and aerial imagery at various spectral and spatial resolutions, high resolution LIDAR data for digital elevation and digital surface models and synthetic aperture radar imagery (SAR). A combination of in-house and commercial software was used to ingest and process these data. The optical imagery was processed and enhanced using various spectral combinations and high pass filtering to generate the highest possible spatial-resolution for each sensor. Classic neural networks analysis was used to classify the optical imagery for vegetation. The SAR imagery was calibrated (for all polarizations) and geometrically corrected to remove layover effects. The processed optical and SAR imagery, LIDAR and ancillary products were co-registered and imported into a GIS system for final analysis and applications.

The optical imagery provided information about surface feature such as lake outlines, general drainage, active channels in Colville River, general lake ice conditions, classification of vegetation types etc. The LIDAR data were used to generate slope maps (for arctic vehicles), general topographic conditions and field operations. The SAR imagery was used to monitor surface conditions when optical imagery was not available during the Arctic night conditions. SAR imagery was also used to calculate the ice thickness proxy maps for eventual field operations. All of these products contributed directly to our environmental baseline studies, improved our field operation efficiency and general safety of our Arctic Operations.

For a practicing engineer (individual or team) The remote sensing data and derived products for Arctic Operations were made available via GIS system. This allowed easy integration with other data layers as well as a common background for all different disciplines to monitor progress and to contribute their learnings and ideas to the entire team.
Transient Flow Assurance Analysis to Optimize Freeze Prevention Procedure in Alaska Nikaitchuq Oil Producers
Authors: Cresta D. , Hester K. C. , Lullo A. G. Di , Atencio L.
Published: October 2018

In the Alaskan North Slope field of Nikaitchuq, the standard shut-down strategy of oil producers was to inject warm diesel inside the tubing of the wells for freeze prevention of the tubing. The procedure requires that a Gas Lift Valve (Shear Orifice Valve) located at 2,000 ft be ruptured to displace the tubing fluid inside the annulus. It was desired to evaluate whether this procedure could be avoided to reduce both operational risk and costs associated with this strategy.

An evaluation was performed using a transient fluid-dynamic simulator based on oil producers. Based on geothermal gradient acquired by DTS fiber optic technology and considering the salinity of formation water, the depth of the tubing under freezing risk was defined. Simulations were performed for both the rate of cooling of the produced fluids in the tubing and the time required to reach ice formation conditions.

In the paper, we will show that the sweeping effect of gas during production does not allow for water accumulation at the x-mas tree and surface piping. In addition, the vertical geometry in the tubing results that any water present falls below the permafrost line during shut-in conditions. As no bulk water is present in the well inside of the ice stability region, the risk of a blockage from ice is not present during a planned shutdown and the previous preservation strategy is not required.

The change in the standard operating procedure for planned shutdowns was successfully applied, leading to a marked reduction of costs and reduced down-time with a consequential recovery of otherwise lost production.
Ice Mode and Beyond: Electrical Propulsion for Efficient Ice-Breaking
Authors: Barisic Matko , Parrondo Yago Martinez , Lee Bo-Won , Wendt Frank
Published: October 2018

This paper presents a novel electrical propulsion method, and a decentralized control system implementation, inclusive of hardware and software (algorithm), for LNG-fueled ice-breakers. The customer value of the method is the avoidance of switch-over of the prime movers on-board from LNG to Diesel on propeller stall-out due to heavy ice-breaking conditions. The paper describes an implementation running on the ice-breaking LNG carriers Christophe de Margerie and Eduard Toll. In addition to previous published work, this paper presents analyses of the installation of energy storage for the absorption and peak-shaving of generation-side over-production of electrical power in the event of intermittent propeller stall-outs when ice-milling.
Development of Propulsion Technology of Tankers Operating in Ice
Authors: Wilkman Göran , Hänninen Samuli , Heideman Torsten , Lehti Matti
Published: October 2018

Ships transporting different liquids have been around for as long as there has been the need to trade between countries and nations. The first liquid transport happened in drums loaded into the ships like any cargo. During the last 120 years as ships have been built of steel/iron it has been possible to transport liquids in tanks built in to the structure of the ships.

During the 20th century cargo ships sailing in ice were assisted seasonally mostly by icebreakers. Most of the liquid transport did not really need any assistance in ice conditions as there was hardly any winter traffic. The continuous need for utilizing oil lead to new territories and the oil discovered in Alaska in the late 1960ies brought up the crude oil transport in ice conditions and Esso started the Manhattan project. This unfortunately did not start the arctic tanker transport. This paper discusses the development history of the propulsion of tankers working in ice conditions.

In the early 1970ies the winter traffic in Finland exploded as the Finnish government decided to keep all the major ports open year-round. This started serious development of ships capable of more independent ice operation. The first propulsion solutions were modifications of well proven technology. We had fixed pitch and controllable pitch propellers connected directly to low speed diesel engines or through a gearbox. In some applications the propeller was equipped with a nozzle. In the 1970ies and 1980ies we were already drafting different tankers with electric propulsion with huge power. However, it was needed a decade more and the development of the propulsion devices from direct shaft lines to azimuth devices to get the propulsion revolution going at full speed.

Today we have available and most commonly used; traditional fixed pitch propellers with conventional shaft lines, mechanical Z-drives and podded propulsors driven by electric motors. The operational profile and mission of the vessel will dictate how the tanker will be furbished.

Most of the new concepts have been tested and developed in conjunction of icebreaker development, where tankers have been closely following. Recently there have been delivered and designed new icebreakers, icebreaking shuttle tankers and LNG carriers. Many of these vessel concepts are relying on podded propulsion system. AZIPOD propulsion has been selected to many of these vessels as it provides excellent ice performance for the vessel, good torque characteristics for the propeller and there already exists proven track record of ice operations. This paper will introduce some outstanding full-scale experience from the revolutionary icebreaking LNG carrier Christopher de Margerie.
Continuous Improvement in Wellbore Position Accuracy: Ultra-Extended-Reach Drilling in Far Eastern Russia
Authors: Poedjono Benny , Maus Stefan , Rawlins Sheldon , Zachman Nicholas , Row Adam Paul , Li Xiong
Published: October 2018

Drilling ultra-extended-reach (ultra-ERD) wellbores has redefined industry standards. Operators and service companies must fully assess the accompanying risks to maximize the overall productivity of an asset. New drilling technologies, such as improved drilling fluid design and geomechanics analyses, allow wellbores to be drilled to the lateral displacement of greater than 13 km. This requires improved absolute wellbore positioning, in conjunction with reduced uncertainties. When developing these drilling technologies, the economics must be considered so as not to exponentially increase the cost per barrel of oil. The increase in infill drilling of nearby offset wellbores requires developing improved methods that reduce wellbore position uncertainty when placing the wellbore in the reservoir, in addition to avoiding collisions.

The proposed geomagnetic referencing technique is suitable for the application to the Sakhalin-1 project in eastern Russia. Here there is a predominance of ultra-ERD wellbores coupled with considerable knowledge of the varying depth of the basement rock structure. This paper presents a process used for creating a geomagnetic crustal field model that can be updated to the actual survey location with the date and time for real-time application. This process can also be used in the reprocessing of legacy measurement-while-drilling (MWD) data. The application of this process significantly improves wellbore position accuracy. The ability to have a greater understanding of the overall geomagnetic field, along with enhanced techniques in multistation algorithm processing, removes the effects of drillstring and the cross-axial interference due to mud shielding effects. Additional benefits of this application include reduced wellbore tortuosity for planned wells, improved anticollision separation factors, and improved torque and drag profiles.

This new geomagnetic model, updated to the actual survey location, date, and time and incorporating realistic uncertainty determinations based on basement rock depth analysis, has resulted in a 50% improvement in the overall ellipse of uncertainty (EOU) when compared with previous definitive surveys, in addition to an accurate bottomhole location. Incorporating these advanced techniques reduces position uncertainty that improves overall 3D wellbore positioning. Other studies, such as a disturbance field study, evaluate the effects of the magnetospheric ring current, auroral electrojets, and secondary induced fields, and was conducted by analyzing the magnetic observatory data from the same magnetic latitude to quantify the maximum and minimum declination variations during a magnetic storm.
Analysis of toxicity from the effluent generated in a furniture industry spray booth using the species Lactuca sativa and Allium cepa
Authors: Bolonhesi Isabela Bruna de Tavares Machado , Lopes Deize Dias
Published: October 2018

This study evaluated the toxicity of effluent generated in a furniture industry spray booth, before and after treatment in a system composed of an anaerobic sequencing batch (ASBR) followed by an aerobic sequencing batch reactor (SBR). The toxicity tests were carried out with raw (with and without dilutions) and treated effluent to evaluate the toxic potential using Allium cepa and Lactuca sativa as bioindicators.  The toxicity tests, using Allium cepa and Lactuca sativa, indicated that the anaerobic-aerobic treatment performed was efficient to reduce the toxicity of the paint booth effluent. The raw effluent, undiluted and diluted (at 1:10; 1:8 and 1:6 dilutions), showed toxic effect on the root growth of Allium cepa, as it inhibited root growth by 100%. In the tests with Lactuca sativa seeds, there was partial inhibition, between 44% and 63%, for 1:10 and 1:8 dilutions, but for the 1: 6 dilution and without dilution of effluent the inhibition was 100%. The treated effluent, in an ASBR followed by an SBR, presented a small percentage of inhibition for tests with Allium cepa (13%) and Lactuca sativa seeds (4%). The effluent treated by the anaerobic system followed by aerobic presented low toxicity without generating lethal or sub-lethal effects to the test organisms, which indicates the efficiency of the treatment process.
Roman Tribune Cola di Rienzo (1347), Res Gestae Divi Augusti and Lex de Imperio Vespasiani
Authors: Lovenjak Milan
Published: October 2018

The anonymous and fragmentarily preserved Romance-dialect Chronicle describing the history of Rome in 1325–1360, the extensive correspondence between Cola di Rienzo (1313–1354) and rulers, nobles, Church dignitaries, and intellectuals (especially Petrarch) in Italy and abroad, as well as various documentary sources allow us to trace Rienzo’s career in considerable detail. A papal notary, a scholar in Classical literature, an exceptional orator and a copyist and translator of Ancient Roman inscriptions, Rienzo, aided by a group of followers, overthrew the baron rule in Rome in May 1347, assumed the title of ‘Roman Tribune’ and seized power with the aim of reuniting Italy under a common emperor, a concept modelled on the first Roman emperor, Augustus. After undertaking a number of more or less successful measures, public manifestations and diplomatic activities, he was forced to retreat by a clash with the barons’ army even before the end of the year. After years of exile, he returned triumphant in the middle of 1354 to seize power, but the first few weeks of tyranny and arbitrary measures led to his tragic demise at the hands of an infuriated mob. Later he grew into the subject of myth, portrayed in numerous literary, musical, and dramatic adaptations. The present paper examines two ancient documents crucial to the formation of the principate (the renewal of which was Cola’s objective), i.e. Augustus’ account of his own deeds (Res gestae divi Augusti), which is mentioned by Suetonius and known from three epigraphically attested copies from Asia Minor, and a bronze plaque bearing a law on the conferment of powers on Emperor Vespasian, the so-called Lex de imperio Vespasiani. The plaque was used as propaganda by Cola during his preparations for the coup. The inconsistencies between the parts of the law preserved on the plaque (it must have been preceded by at least one other plaque) and the account of Cola’s interpretation as given in the anonymous Chronicle raise a number of questions, which resist definitive answers.

En dichos embalses existen diferencias en la acumulación de sedimentos, los limos, se concentran en las zonas estancadas y más profundas mientras que las arenas en las entradas de los drenajes a los embalses. Existe una marcada tendencia estacional de la sedimentación con valores máximos durante los meses de lluvias y se observan diferencias composicionales y granulométricas espaciotemporales. Una simulación de la evolución sedimentaria de estos tres embalses indica su posible desaparición como depósito de agua de continuar los aportes de sedimentos desde los tributarios, siendo más drástica en Porce II.
Domestic architecture in 16th century Seville: San Salvador
Authors: Núñez-González María
Published: October 2018

This study is based on historical documents belonging to the most important ecclesiastical institution in Seville during the 16th century. The Cathedral’s archives have been consulted, with special focus on the section devoted to books of written descriptive records of houses (called ‘apeos’) that belonged to the Cabildo (Chapter) in 1542. These records not only documented the physical distribution of the houses with measurements in Castilian yards of the different parts of the house, but also described the more qualitative features of the interior architectural design. The main purpose of this study is to characterize the typical Sevillian houses from historical documents of the period focused on the collation of San Salvador. By way of a novel methodology, the following steps have been developed: first, an architectural analysis; second, a typology of houses based on functions, dimensions, construction, lay-out, etc.; third, a detailed glossary of architectural terms listed to permit a rigorous understanding of the domestic architecture in 16th century Seville; and finally, an example of every documented record has been drawn. Among the most significant conclusions is that the Sevillian dwellings of that period reflected the Islamic terminology, architecture, construction and lay-out typical of Andalusia, but with distinctive features of Sevillian housing.
Las salas Cinéac de Adrienne Gorska y Pierre de Montaut: adaptar un “tipo”
Authors: Moreno Maria Pura
Published: October 2018

From the 1930’s on, a variant in the western architecture of movie theatres built in previous decades came to light. This variant, smaller and more unassuming in its decoration and size, was the result of another economic context and, above all, of a novel programming of newscasts and documentaries in short sessions and continuous slideshows called, depending on the country of your projection, ‘newsreels’, ‘cinegiornali’, ‘actualités filmées’, or ‘wochenschauen’. The establishment of the chain of movie theatres ‘Cinéac -cinéma et actualités’ in French-speaking countries, mainly by the entrepreneur Reginald Ford, gave rise to the proposal of spatial and technical answers to the demands of aspects such as acoustics, optics, a continuous flow of people, safety or ventilation, from the sector of architecture which was most functionalist. In this article the Cinéac built by the architects Adrienne Gorska and Pierre de Montaut, pioneers in projects for this program of leisure, will be analysed. The aim is to demonstrate the technical rigor on which constructiveness, as the leitmotiv of longed for perception, was based. The critical re-reading of layouts and sections will reveal that, behind the prominence of bright facades, there were hidden spatial criteria different from those of the previous cinemas, leading to, as a whole, what was to be a typological adaptation to a function that had already been established

Constraints on Enhanced Weathering and related carbon sequestration – a cropland mesocosm approach

Published: November 2018

Abstract. The weathering of silicates is a major control on atmospheric CO2 at geologic time scales. It was proposed to enhance this process to actively remove CO2 from the atmosphere. While there are some studies that propose and theoretically analyze the application of rock powder on agricultural land, results from field experiments are still scarce. In order to evaluate the efficiency and side effects of Enhanced Weathering, a mesocosm experiment was set up and agricultural soil from Belgium was amended with olivine-bearing dunite ground to two different grain sizes, while distinguishing setups with and without crops. Based on measurements of Mg, Si, pH, and DIC, the additional weathering effect of olivine could be confirmed. Calculated weathering rates are up to three orders of magnitude lower than found in other studies. The calculated CO2 consumption by weathering was comparably low with 2.3 to 4.9 CO2 t km−2 a−1. One identified cause was preferential flow leading to a low water-rock interaction time for a significant water volume in the setup, not addressed in previous Enhanced Weathering experiments for CO2 consumption. Correction for preferential flow leads to fluxes about a magnitude higher, confirming that this process and surface runoff in the field must be included in assessments for the CO2 consumption potential of Enhanced Weathering in general. Pore water Mg / Si molar ratios suggest that dissolved Si from the added minerals stays in the system over the observation period, because a cation depleted Si layer forms on the reactive mineral surface of freshly ground rocks. This layer has not reached equilibrium thickness within the first two years. The release of potentially harmful trace elements is an acknowledged side effect of Enhanced Weathering. Primarily Ni and Cr are elevated in soil solution, while Ni concentrations exceed the limits of drinking water quality. The use of olivine, rich in Ni and Cr, is not recommend and alternative rock sources are suggested for the application.
Wave run-up prediction and observation in a micro-tidal beach

Published: November 2018

Abstract. Extreme weather events bear a significant impact on coastal
human activities and on the related economy. Forecasting and hindcasting the
action of sea storms on piers, coastal structures and beaches is an important
tool to mitigate their effects. To this end, with particular regard to low
coasts and beaches, we have developed a computational model chain
based partly on open-access models and partly on an ad-hoc-developed
numerical calculator to evaluate beach wave run-up levels and flooding. The
offshore wave simulations are carried out with a version of the WaveWatch III
model, implemented by CCMMMA (Campania Centre for Marine and Atmospheric
Monitoring and Modelling – University of Naples Parthenope), validated
with remote-sensing data. The waves thus computed are in turn used as initial
conditions for the run-up calculations, carried out with various empirical
formulations; the results were finally validated by a set of specially
conceived video-camera-based experiments on a micro-tidal beach located on
the Ligurian Sea. Statistical parameters are provided on the agreement
between the computed and observed values. It appears that, while the system
is a useful tool to properly simulate beach flooding during a storm,
empirical run-up formulas, when used in a coastal vulnerability context, have
to be carefully chosen, applied and managed, particularly on gravel beaches.
Do wind turbines pose roll hazards to light aircraft?

Published: November 2018

Abstract. Wind energy accounted for 5.6 % of all electricity generation
in the United States in 2016. Much of this development has occurred in rural
locations, where open spaces favorable for harnessing wind also serve general
aviation airports. As such, nearly 40 % of all United States wind turbines exist
within 10 km of a small airport. Wind turbines generate electricity by
extracting momentum from the atmosphere, creating downwind wakes
characterized by wind-speed deficits and increased turbulence. Recently, the
concern that turbine wakes pose hazards for small aircraft has been used to
limit wind-farm development. Herein, we assess roll hazards to small aircraft
using large-eddy simulations (LES) of a utility-scale turbine wake. Wind-generated
lift forces and subsequent rolling moments are calculated for hypothetical
aircraft transecting the wake in various orientations. Stably and neutrally
stratified cases are explored, with the stable case presenting a possible
worst-case scenario due to longer-persisting wakes permitted by lower ambient
turbulence. In both cases, only 0.001 % of rolling moments experienced by
hypothetical aircraft during down-wake and cross-wake transects lead to an
increased risk of rolling.

Las técnicas de generación de ideas son herramientas orientadas a la resolución de problemas de diversa índole, siendo instrumentos que impulsan el potencial creativo de las personas con el objetivo de generar muchas ideas en poco tiempo. En este trabajo se realiza una revisión de las principales técnicas de generación de ideas con aplicación en el ámbito de la publicidad y se analiza su grado de conocimiento y uso por parte de los profesionales de las agencias publicitarias españolas. Para ello, se revisaron 15 técnicas y se realizaron 22 entrevistas. La inmensa mayoría de los entrevistados conocen varias técnicas y se muestran de acuerdo con su utilidad en mayor o menor grado, siendo el brainstorming la técnica por excelencia. Aunque el grado de uso es alto y diverso, los creativos publicitarios prefieren, en muchos casos, utilizar métodos propios que, no obstante, guardan relación con las técnicas más conocidas.

A Universidade Regional Integrada do Alto Uruguai e das Missões (URI) completa, no ano de 2017, seus 25 anos no município de Cerro Largo, tendo como missão institucional, a formação de profissionais baseados na ética e no comprometimento com a comunidade. Sob essa orientação da missão da universidade, a disciplina de Fundamentos de Marketing do curso de Administração, na qual são desenvolvidos conceitos de Marketing Social dá sustentação para algumas ações que tentam responder aos movimentos da sociedade, que passam a exigir um novo papel das organizações, que extrapolam a geração de lucros e empregos, e que fazem surgir as discussões sobre Marketing e Responsabilidade Social das Organizações. Assim surgem novas expectativas sobre as atuações organizacionais e universitárias, sob o mote da noção de Responsabilidade Social Universitária. Em discussão análoga, uma das funções das universidades passa a ser considerada terreno fértil para as ações que perfazem um elo entre essas instituições e a sociedade, e portanto, a relação da extensão universitária, como reflexo da relação universidade e sociedade. Com esse posicionamento epistemológico se constrói o estudo com o objetivo de apresentar um relato de experiência dessa atuação de extensão universitária e responsabilidade social executadas por discentes, docentes e técnicos-administrativos desta instituição. Tais ações são conduzidas pelos pressupostos teóricos da Extensão Universitária, da Responsabilidade Social e Responsabilidade Social Universitária, com vistas à construção de um processo educativo para a intervenção no desenvolvimento de Cerro Largo e região adjacente.

Tendo em vista o potencial alimentar das plantas alimentícias não convencionais-PANC’s, este trabalho buscou registrar uma experiência de produção e comercialização por parte dos agricultores da horta urbana comunitária da COHAB (Companhia de habitação do estado de Minas Gerais), localizada no município de Lavras, Minas Gerais, Brasil. A coleta de informações se deu através de entrevistas realizadas individualmente aos agricultores em suas áreas de cultivo, oficinas e visitas a campo. Observou-se que a utilização plantas alimentícias não convencionais possibilita as famílias agricultoras qualidade de vida e geração de renda extra. Neste caso, a geração de renda não se dá somente com a venda direta dos produtos, mas também na economia que as famílias fazem ao diminuírem a compra de alimentos e medicamentos. A partir dos resultados foram planejados cursos e palestras para os agricultores e construído coletivamente (pesquisadores e agricultores) uma cartilha contendo informações sobre as espécies de PANC’s produzidas e comercializadas na horta, com o intuito de divulgar e incentivar o consumo e produção destas hortaliças.
Habitat Saudável e Sustentável no Territótio Paulo Freire
Authors: Morais Liliana Esteves
Published: October 2018

Este artigo tem como objetivo apresentar relatos do Projeto de Extensão Habitat Saudável e Sustentável da Universidade do Extremo Sul Catarinense (UNESC), que atua desde 2016 no Bairro Progresso, em Criciúma, Santa Catarina. O bairro é pertencente ao Território Paulo Freire, recorte localizado a oeste do centro do município, abrangendo diversas comunidades socioeconomicamente desfavorecidas, que estão, em sua maioria, associadas com ocupações clandestinas e/ou irregulares. Faz parte do ideal do projeto perceber como se estabelecem as relações com o meio nesses locais, e através desse movimento identificar as noções de apropriação dos espaços, identificação, personificação, cultivação e sentimento de pertença, (GONÇALVES, 2014) tanto para os espaços individuais, como também nos espaços coletivos. O desenvolvimento metodológico do trabalho foi planejado, essencialmente, em quatro etapas: (1) Levantamento de Campo com Leitura Técnica, (2) Oficina de Mobilização e Sensibilização por meio da Leitura Comunitária, (3) Cruzamento da Leitura Técnica e Comunitária e (4) Contato com a Comunidade. Dessa forma, o Projeto de Extensão Habitat Saudável e Sustentável se concretiza através da discussão com a comunidade, buscando a horizontalização entre saberes, favorecendo espaços de trocas e de construção coletiva, e almejando a autonomia e o empoderamento dessa população frente às problemáticas a serem enfrentadas.
