Opettajien työelämäjaksojen kehitysprojektien mallintaminen osaksi Etelä-Karjalan ammattiopiston toimintaa

Tämän diplomityön tavoitteena oli selvittää, kuinka pilottiprojektien pohjalta voidaan kehittää toimiva prosessimalli. Prosessi, johon uudenlaista kehitystapaa lähdettiin hakemaan, oli Etelä-Karjalan ammattiopiston opettajien työelämäjaksojen toteutusprosessi. Opettajien työelämäjakson erilaisia toteutusmalleja oli testattu jo useammassa eri erilaisten rahoitusten avustuksella perustetuissa pilottiprojektissa. Ulkopuolisen rahoituksen päättyessä tuli ajankohtaiseksi kehittää Etelä-Karjalan ammattiopistolle oma työelämäjaksojen toteutusmalli. Mallin kehitystyössä voitiin hyödyntää aikaisemmista projekteista saatuja palautteita, jolloin mallin kehitystyö lähti liikkeelle tiedossa jo olevista asiakkaan toiveista ja tarpeista. Toimintaa kehitettiin prosessina, koska Etelä-Karjalan ammattiopistossa on alettu satsaamaan voimakkaasti laatuun ja laadun jatkuvaan parantamiseen. Laatua taas ei synny ilman, että toiminnat määriteltäisiin ja kuvattaisiin prosesseina. Koska koulutusorganisaatioille prosessiajattelu on vielä aika vierasta, tässä työssä selvitettiin ensin teoriakatsauksen pohjalta, mitä prosessiajattelu tarkoittaa ja mitä hyötyjä sillä voidaan saavuttaa julkisella sektorilla. Lisäksi kartoitettiin niitä tapoja ja keinoja, joiden avulla prosesseja voitaisiin parantaa ja uudistaa. Prosessin uudistamisprosessiin löytyi teorian pohjalta työkalu, jota muokattiin niin, että sitä voitiin hyödyntää juuri tämäntyyppisessä uudistustyössä. Työn lopputuloksena syntyi työelämäjakson toteutusta kuvaava prosessimalli, jota on jatkossa tarkoitus testata ja kehittää työelämäjaksoilta saadun palautteen perusteella.

Alueellisen innovaatiojärjestelmän kehityspolku - case Kouvolan seutu

Tutkimus on esiselvitystyö, jonka tavoitteena oli selvittää miten luoda innovaatiojärjestelmä Kouvolan seudulle. Lisäksi tavoitteena oli selvittää alueen innovaatiojärjestelmän nykytila, tutkia miten toimijat saadaan sitoutumaan ja toimimaan kohti yhteistä päämäärää sekä kuvata prosessi kehitystyölle. Kouvolan seudulla on tapahtunut lähiaikoina runsaasti muutoksia, jotka vaikuttavat myös innovaatiotoimintaan. Kehitystä on tapahtunut, mutta kehitystä on kiihdytettävä, jotta alue on tulevaisuudessa elinvoimainen seutu asua ja yrittää. Suoritettujen kahdeksan asiantuntijahaastattelun pohjalta voidaan todeta, että Kouvolan seudulla ei nykyisellään ole innovaatiojärjestelmää. Kouvolan seudulla on innovaatiojärjestelmän osia, mutta toiminta on hajanaista ja toimijoilla ei ole selkeää kuvaa omasta roolistaan osana kokonaisuutta. Innovaatioiden syntyä ei voi jättää sattuman käsiin, vaan uusien innovaatioiden syntyminen vaatii yhteistyötä ja vuorovaikutusta eri yritysten ja organisaatioiden välillä. Innovaatiojärjestelmän luomiseen Kouvolan seudulle ei ole yhtä oikeaa ja helppoa tietä. Harmaakorven alueellinen kehitysalustamenetelmä tarjoaa selkeän prosessin kehitystyöhön, mutta onko Kouvolassa tarvittavia resursseja ja osaamista prosessin läpivientiin? Tulisiko lähteä liikkeelle pienistä asioista, yhteisesti määritellyistä käsitteistä, päämääristä ja rooleista. Yhtenä ratkaisuna on Kouvolan seudun innovaatio-ohjelman rakentaminen, jossa nämä määritellään. Ohjelman kehittämisessä on syytä olla mukana mahdollisimman laajalti innovaatiojärjestelmän toimijoita, mutta kehittämisprosessin on syytä olla kevyt. Jo ohjelmaa kehittäessä tarvitaan erilaisia pilot-projekteja ja foorumeita, joiden kautta Kouvolan seudun innovaatiojärjestelmää saadaan kehitettyä ja pikku hiljaa rakennettua luottamusta ja yhteistyötä. Tekemisen kautta tietoisuus toiminnasta ja sen eduista leviää, ja Kouvolan seudun saadaan luotua toimiva alueellinen innovaatiojärjestelmä.

Working capital management in the small and medium-sized enterprises Case: Project-based business environment in Flowrox Oy

This Master´s thesis illustrates how growing a business ties up the company´s working capital and what the cost of committed capital. In order to manage a company´s working capital in rapid business growth phase, the thesis suggests that by monitoring and managing the operating and cash conversion cycles of customers´ projects, a company can find ways to secure the required amount of capital. The research method of this thesis was based on literature reviews and case study research. The theoretical review presents the concepts of working capital and provides the background for understanding how to improve working capital management. The company in subject is a global small and medium-sized enterprise that manufactures pumps and valves for demanding process conditions. The company is expanding, which creates lots of challenges. This thesis concentrates to the company´s working capital management and its efficiency through the supply chain and value chain perspective. The main elements of working capital management are inventory management, accounts receivable management and accounts payable management. Prepayments also play a significant role, particularly in project-based businesses. Developing companies´ working capital management requires knowledge from different kind of key operations´ in the company, like purchasing, production, sales, logistics and financing. The perspective to develop and describe working capital management is an operational. After literature reviews the thesis present pilot projects that formed the basis of a model to monitor working capital in the case company. Based on analysis and pilot projects, the thesis introduces a rough model for monitoring capital commitments in short time period. With the model the company can more efficiently monitor and manage their customer projects.

Promoting Cleantech in Emerging Markets: Business Model for Waste Pre-treatment Equipment in China

Waste incineration is becoming increasingly widespread method of waste disposal in China. Incineration plants mostly use grate and circular fluidized bed (CFB) technology. Waste combustion in cement production is also beginning to gradually increase. However, Chinese waste composition is causing problems for the energy utilization. Mechanical waste pre-treatment optimizes the combustion process and facilitates the energy recovery. The objective of this study is to identify how Western waste pre-treatment manufacturer could operate in Chinese markets. Chinese waste management industry is reviewed via PESTEL analysis. The current state and future predictions of grate and CFB incineration as well as cement manufacturing are monitored. Grate combustion, which requires lesser waste pre-treatment, is becoming more common at the expense of CFB incineration in China. The most promising future for waste treatment is in cement production industry. Waste treatment equipment manufacturer should try to create pilot projects with biggest cement producers with a view of growing co-operation in the future.

Pienjännitteisen tasasähkönjakelun hyödyntäminen ja siihen liittyvä tutkimus maailmalla

Tässä kandidaatintyössä selvitetään kirjallisuustutkimuksena, minkälaista tutkimusta maailmalla on tehty liittyen pienjännitteiseen tasasähkönjakeluun, sekä missä sovelluskohteissa sitä hyödynnetään. Työssä esitetään yleisimmät järjestelmärakenteet ja sovelluskohteet sekä organisaatiot, joiden on havaittu tutkivan tasasähkönjakelua kiinteistöissä, microgrideissä tai julkisessa sähkönjakelussa. Katsauksen perusteella havaittiin, että maailmalla on tehty erityisesti laskennallisia tutkimuksia ja simulointeja liittyen pienjännitteiseen tasasähkönjakeluun. Näkökulma on pääasiassa ollut kiinteistöissä ja microgrideissä, vähäisemmässä määrin myös julkisissa sähkönjakeluverkoissa. Pienjännitteistä tasasähkönjakelua hyödynnetään, tai ainakin voitaisiin hyödyntää näissä kohteissa. Pääasiassa konseptilla on pyritty hakemaan kustannussäästöjä ja toisaalta parantamaan hyötysuhdetta. Ympäri maailmaa on käynnissä pilottihankkeita sekä kiinteistöihin, että julkiseen sähkönjakeluun liittyen. Bipolaarinen ratkaisu näytti olevan yleisempi. Käytetyt ja tutkitut jännitetasot vaihtelivat riippuen sovelluskohteesta – kiinteistön sisällä oli käytössä tasot pienoisjännitteestä aina 350–400 VDC jännitetasoon asti, ja sama 350–400 VDC oli selvästi suosittu jännitealue myös jakeluverkossa, mutta myös korkeampia jännitteitä, kuten 700–750 VDC, oli käytössä.

Development of modular roll service concepts

The goal of this study was to find and develop new or improved service concepts for rolls in a paper machine and secondary targets were to find out what the KPIs and values of the concepts are. Two methodologies were utilized in researching this problem; firstly sales personnel were interviewed about customer values and KPIs and a questionnaire about service modules were sent out to four BSI (basic sales item) responsible persons. Throughout the research process differences in geographic regions were identified and several customer KPIs and values were discovered. The interviews showed that the main concern for customers is the cost of operations. The goal is to produce the same or in some cases more tons with smaller operating costs. The questionnaire standardized the data about service modules and made it possible to link these values, KPIs and concerns of customers to Valmet’s service offering. Eventually these service modules were used to create a service concepts that offer flexibility, cost savings, safety and peace of mind for the customers. With this new conceptual approach Valmet can more flexibly answer to customer quotations and modify the offering to better generate customer value and customer satisfaction. In addition a new BSI was defined and proposed for pilot projects.

Social Media Use in Medical and Health Professional Education: Role of the Librarian on a Faculty Steering Committee

Objective: An interprofessional steering committee was created at Université de Montréal’s Faculty of Medicine to examine how social media are integrated in medical and health professional education in universities across the globe, and to propose a strategic plan for integrating social media in the Faculty’s various curricula. This presentation will summarize the steering committee’s work and describe the librarian’s contribution. Methods: The Committee’s project leader first conducted a literature search on best practices of social media in medical and health professional curricula. A reference website was then created (mse.med.umontreal.ca) to provide easy access to a large number of the articles and resources reviewed. A steering committee was constituted and 11 meetings were held over a 9-month period. The Committee comprised 18 members and included assistant deans, academic program directors, professors, communication advisors, undergraduate and graduate students and a librarian. An online survey on social media use by students and professors of the Faculty was conducted, ten pilot projects were put forward and a three-year strategic plan was proposed. Results: A total of 1508 students and 565 professors participated in the survey. Results showed that both groups had a strong interest in learning how social media could be integrated in academic and professional activities. Participants reported concern with risks associated with social media use and expressed the need for a Faculty policy and guidelines. The librarian’s contribution to the steering committee included: writing posts on the website’s internal blog, assisting in the design of the survey questionnaires and writing the final report’s survey results chapter. She also proposed two pilot projects: creating a social media learning portal and an altmetrics workshop. Conclusions: Based on the literature review and the survey results, the Committee affirmed the importance of integrating social media in the various study programs of the Faculty of Medicine. Despite the restricted timeline, this interprofessional steering committee was able to carry out its mandate because of the leadership and expertise of each of its members. As the librarian had the most experience with the use of social media in a professional context, her knowledge was instrumental in assisting the project leader in a group mainly composed of social media non-users.

Kompetenzraster aus dem schweizerischen Institut Beatenberg - eine Option für berufliche Schulen in Deutschland?

Der Name einer kleinen Internatsschule im Berner Oberland taucht zunehmend in den Diskussionen über die Gestaltung von selbst organisiertem Lernen auf: Institut Beatenberg. Der Direktor des Instituts, Andreas Müller, und seine Mitarbeiter sind gefragte Referenten auf Veranstaltungen über die Einführung einer Lehr-Lernkultur, die den Lernenden und seine Lernprozesse in den Mittelpunkt der pädagogischen Arbeit stellt. Zudem finden ihre Publikationen zunehmendes Interesse im gesamten deutschsprachigen Raum. Ein Schlüsselinstrument wurde dabei zum Schlagwort: Kompetenzraster. Doch die stellen nur eines der Instrumente dar, die den ‚Wirkungskreislauf des Lernerfolgs’ in Beatenberg stützen. Berufliche Schulen in Hessen und Hamburg haben im Rahmen von Modellprojekten mit der Erarbeitung von Kompetenzrastern nach den Vorbildern in Beatenberg begonnen und versprechen sich damit eine neue, auf selbst organisiertem Lernen aufbauende kompetenzorientierte berufliche Bildung. In dem Beitrag werden die Arbeit mit Kompetenzrastern und den dahinter liegenden ‚Lernlandschaften’ sowie der ‚Wirkungskreislauf den Lernerfolgs’ in Beatenberg kompetenzorientiert dargestellt. Die Dimensionen Definition, Beschreibung, Ordnung, Erwerb, Messung und Anerkennung von Kompetenzen werden herausgearbeitet und die Möglichkeiten von Kompetenzrastern in der beruflichen Bildung kritisch gewürdigt. Der Beitrag ist entlang der genannten Dimensionen gegliedert.

Condiciones generales para la revitalización de áreas urbanas en desuso con sospecha de contaminación en Latinoamérica

La revitalización de áreas urbanas en desuso, muchas veces bajo sospecha de contaminación, tiene un gran potencial no solo para la renovación urbana, sino también para aumentar la cohesión social en las ciudades latinoamericanas y fomentar activamente el desarrollo urbano sostenible. A  pesar de ello, es una estrategia que ha recibido poca atención en la mayoría de países de Centro y Sur América, pero ya muestra en Europa resultados alentadores. El proyecto Integration lleva  tres años trabajando con seis ciudades latinoamericanas –incluida Bogotá–, en cooperación con  Stuttgart, Alemania, y está financiado por la Comisión Europea bajo su programa URB-AL III,  para poner a prueba la viabilidad de introducir estas prácticas. Este artículo resume las lecciones hasta ahora aprendidas en los proyectos piloto, y hace seis recomendaciones puntuales basadas en  estas experiencias, a través la revisión de los modelos guía de desarrollo urbano, los campos de acción y los proyectos de revitalización ya concluidos.

Ocean data dissemination: new challenges for data integration

In the decade since OceanObs `99, great advances have been made in the field of ocean data dissemination. The use of Internet technologies has transformed the landscape: users can now find, evaluate and access data rapidly and securely using only a web browser. This paper describes the current state of the art in dissemination methods for ocean data, focussing particularly on ocean observations from in situ and remote sensing platforms. We discuss current efforts being made to improve the consistency of delivered data and to increase the potential for automated integration of diverse datasets. An important recent development is the adoption of open standards from the Geographic Information Systems community; we discuss the current impact of these new technologies and their future potential. We conclude that new approaches will indeed be necessary to exchange data more effectively and forge links between communities, but these approaches must be evaluated critically through practical tests, and existing ocean data exchange technologies must be used to their best advantage. Investment in key technology components, cross-community pilot projects and the enhancement of end-user software tools will be required in order to assess and demonstrate the value of any new technology.

Can REDD+ reconcile local priorities and needs with global mitigation benefits? lessons from Angai Forest, Tanzania

The scope of the reducing emissions from deforestation and forest degradation (REDD) mechanism has broadened REDD+ to accommodate different country interests such as natural forests, protected areas, as well as forests under community-based management. In Tanzania the REDD+ mechanism is still under development and pilot projects are at an early stage. In this paper, we seek to understand how local priorities and needs could be met in REDD+ implementation and how these expectations match with global mitigation benefits. We examine the local priorities and needs in the use of land and forest resources in the Angai Villages Land Forest Reserve (AVLFR) in the Liwale District of Lindi Region in Tanzania. Primary data was collected in two villages, Mihumo and Lilombe, using semistructured key informant interviews and participatory rural appraisal methods. In addition, the key informant interviews were conducted with other village, district, and national level actors, as well as international donors. Findings show that in the two communities REDD+ is seen as something new and is generating new expectations among communities. However, the Angai villagers highlight three key priorities that have yet to be integrated into the design of REDD+: water scarcity, rural development, and food security. At the local level improved forest governance and sustainable management of forest resources have been identified as one way to achieve livelihood diversification. Although the national goals of REDD+ include poverty reduction, these goals are not necessarily conducive to the goals of these communities. There exist both structural and cultural limits to the ability of the Angai villages to implement these goals and to improve forestry governance. Given the vulnerability to current and future climate variability and change it will be important to consider how the AVLFR will be managed and for whose benefit?

Mining in a changing climate: what scope for forestry-based legacies?

This paper provides an interdisciplinary perspective on mine reclamation in forested areas of Ghana, a country characterised by conflicts between mining and forest conservation. A comparison was made between above ground biomass (AGB) and soil organic carbon (SOC) content from two reclaimed mine sites and adjacent undisturbed forest. Findings suggest that on decadal timescales, reclaimed mine sites contain approximately 40% of the total carbon and 10% the AGB carbon of undisturbed forest. This raises questions regarding the potential for decommissioning mine sites to provide forestry-based legacies. Such a move could deliver a host of benefits, including improving the longevity and success of reclamation, mitigating climate change and delivering corollary enumeration for local communities under carbon trading schemes. A discussion of the antecedents and challenges associated with establishing forest-legacies highlights the risk of neglecting the participation and heterogeneity of legitimate local representatives, which threatens the equity of potential benefits and sustainability of projects. Despite these risks, implementing pilot projects could help to address the lack of transparency and data which currently characterises mine reclamation.

Interactive learning in UK construction practice: examining the role of BIM process standards

From a construction innovation systems perspective, firms acquire knowledge from suppliers, clients, universities and institutional environment. Building information modelling (BIM) involves these firms using new process standards. To understand the implications on interactive learning using BIM process standards, a case study is conducted with the UK operations of a multinational construction firm. Data is drawn from: a) two workshops involving the firm and a wider industry group, b) observations of practice in the BIM core team and in three ongoing projects, c) 12 semi-structured interviews; and d) secondary publications. The firm uses a set of BIM process standards (IFC, PAS 1192, Uniclass, COBie) in its construction activities. It is also involved in a pilot to implement the COBie standard, supported by technical and management standards for BIM, such as Uniclass and PAS1192. Analyses suggest that such BIM process standards unconsciously shapes the firm's internal and external interactive learning processes. Internally standards allow engineers to learn from each through visualising 3D information and talking around designs with operatives to address problems during construction. Externally, the firm participates in trial and pilot projects involving other construction firms, government agencies, universities and suppliers to learn about the standard and access knowledge to solve its specific design problems. Through its BIM manager, the firm provides feedback to standards developers and information technology suppliers. The research contributes by articulating how BIM process standards unconsciously change interactive learning processes in construction practice. Further research could investigate these findings in the wider UK construction innovation system.

O poder judiciário e o movimento da qualidade total : aspectos determinantes na implantação do pgqj em um estudo exploratório

Este trabalho analisa fatores que viabilizaram a implantação do Plano de Gestão pela Qualidade do Judiciário em algumas Unidades do Poder Judiciário do RS. Com base na teoria geral da administração, especialmente na teoria clássica, na burocracia e na teoria comportamental, em autores de obras sobre organizações que aprendem e em obras de W. Edwards Deming sobre a nova economia no governo, desenvolve-se essa pesquisa. O estudo analisa a implantação do Plano de Gestão, os resultados dos projetos-piloto e programa de adesão, como os atores do processo perceberam as mudanças ocorridas e como é definida a situação por aqueles que estão à margem dos acontecimentos por diferentes motivos, por meio da análise de documentos do acervo da organização, de dados coletados nas entrevistas com integrantes de Unidades com e sem implantação do gerenciamento da rotina, preconizado pelo modelo da Qualidade Total. Estabelece-se, assim, o quadro de aspectos determinantes na implantação do PGQJ, quais sejam: a estrutura da tarefa, as relações interpessoais e a liderança, o processo decisório e o comprometimento com a organização. Os resultados obtidos delineiam a percepção dos atores quanto ao processo de mudança e suas expectativas quanto à capacidade da organização de absorver novos modelos de gestão, acarretando, em determinados momentos, uma completa quebra de paradigmas. Demonstram, ainda, a distância existente entre a proposição do Plano de Gestão, quanto ao comportamento administrativo, ao desenvolvimento dos recursos humanos, ao envolvimento com o trabalho, e o que efetivamente se verifica nas Unidades da organização. Por fim, discute-se alternativa para a implantação de modelo de gestão baseado na Qualidade Total e na aprendizagem organizacional, sugerindo-se estudos mais aprofundados desses aspectos determinantes, com o objetivo de melhorar o desempenho do projeto em andamento.

Implante endoscópico no esôfago distal de polimetilmetacrilato para controle do refluxo gastrofágico : estudo experimental em modelo animal

XIXA doença do refluxo gastroesofágico (DRGE) comumente afeta o esôfago e provavelmente é a condição mais prevalente no segmento alto do trato gastrointestinal, acometendo entre 5 e 45% da população ocidental. A terapêutica atual para essa doença além de medidas gerais e dietéticas, inclui tratamento farmacológico e/ou cirurgia. Ambos podem ser eficazes, mas apresentam elevado custo financeiro. O tratamento com fármacos pode apresentar baixa aderência medicamentosa e a cirurgia tem baixa, mas não desprezível, morbidade e mortalidade. Idealmente o tratamento da DRGE deveria ser eficaz, com baixo risco e com baixo custo. Objetivos: 1. Desenvolver um modelo experimental em suínos para o estudo do Refluxo Gastroesofágico através da Pressão e do Volume de Vazão Gástricos; 2. Avaliar a eficácia do implante endoscópico de PMMA ao nível do Esfíncter Esofágico Inferior (EEI) para aumentar a Pressão de Vazão Gástrica, o Volume de Vazão Gástrico e a Pressão Basal do EEI; 3. Descrever as reações histológicas associadas ao implante de PMMA. Material e Métodos: Suínos da raça Large White, do sexo feminino com 8 semanas de vida foram estudados no experimento. Foi realizada manometria do esfíncter esofágico inferior com registro da pressão basal com cateter de perfusão com água e técnica de retirada lenta. Calculou-se, também, a extensão do EEI. Após, gastrostomia era realizada com colocação intragástrica da extremidade distal de uma sonda de Foley com três vias e um cateter de pHmetria esofágica introduzido via oral com o sensor distal posicionado 5 cm acima do bordo superior de esfíncter esofágico inferior. Iniciava-se, XXentão, a infusão contínua no estômago de uma solução de HCl a 0,02N com medida e registro simultâneos da Pressão e do Volume de Vazão Gástricos e do pH esofágico. Definiu-se a Pressão de Vazão Gástrica (PVG) e o Volume de Vazão Gástrico quando houve brusca e sustentada acidificação do esôfago distal (pH<3). Após, introduzia-se um tubo metálico (Tubo Introdutor ou TI) via oral e, em seguida, o endoscópio, seguindo ambos até o esôfago distal. Cateter de nylon com agulha calibre 16 era introduzido pelo tubo introdutor e o PMMA implantado na área correspondente ao EEI com uma pistola dosadora volumétrica que permitia a injeção de volumes prédeterminados em 3 ou 4 pontos da submucosa (total por ponto = 0,73 ml de PMMA). As medidas de PVG, VVG e pressão basal do EEI foram repetidas após 28 dias, sacrificando-se os animais e removendo-se esôfago médio e distal, junção esofagogástrica, fundo e corpo gástricos para estudo histológico. Previamente ao experimento, três projetos pilotos foram desenvolvidos. O primeiro designado como “Projeto Piloto: Refluxo Gastroesofágico por pHmetria de 24H” (RGE 24H) buscou a via de acesso transnasal para registro de pHmetria por 24 horas. No segundo, designado “Projeto Piloto: Esofagostomia”, para confirmação de refluxo gastroesofágico espontâneo em suínos da raça Large White, utilizou-se anestesia com associação de tiletamina 125 mg e zolazepam 125 mg em combinação com um sedativo, a xilazina a 2% . A pHmetria foi mantida por 24 horas. Os dados descritos por Kadirkamanathan et al. não foram reproduzidos no nosso laboratório. Optou-se então pela realização de um terceiro projeto, “Projeto Piloto: Gastrostomia” para induzir refluxo gastroesofágico através de um modelo experimental e testar a reprodutibilidade da Pressão de Vazão Gástrica. Obteve-se sucesso. Resultados: Trinta e sete animais foram estudados em 60 intervenções no Laboratório de motilidade experimental. O projeto piloto “RGE:24h” foi abandonado após perda de 5 animais pela anestesia com halotano e, solucionada esta questão, a sistemática infecção do tecido celular subcutâneo nasal, dificultando a manutenção do cateter de phmetria em outros 5 animais. No “Projeto Piloto: Esofagostomia”, em cinco animais estudados (cada animal em duas ocasiões diferentes) não se reproduziram os achados de refluxo espontâneo. No terceiro projeto “Projeto Piloto: Gastrostomia” quatro animais foram estudados em dois momentos diferentes obtendo-se sucesso e reprodutibilidade XXIdos dados. Criado o modelo experimental, quatorze suínos foram submetidos ao experimento com implante endoscópico de PMMA com os seguintes resultados: A média dos pesos com 8 semanas de idade foi 14,98 ± 2,43 e 28 dias após o implante, 20,26 ± 3,68. O ganho ponderal foi considerado normal para a espécie. A Pressão de Vazão Gástrica média no dia 1 foi 8,08 mmHg e no dia 28, 10,69mmHg (Teste t de Student: t = 2,72 gl = 13 p = 0,017). Os Volumes de Vazão Gástricos médios foram: 392,86 ml para o dia 1 e 996,71 ml no dia 28 (teste t de Student: t = 11,66 gl = 13 p< 0,001). A Pressão Basal do EEI e o comprimento do esfíncter, não apresentaram diferenças estatisticamente significativas. PMMA foi identificado como depósitos de grandes vacúolos no tecido intersticial ao exame histológico da junção esofagogástrica associado a histiócitos, plasmócitos e presença de células gigantes tipo Langhans indicando reação tecidual de corpo estranho em todos os animais. Fibrose e macrófagos com vacúolos intracelulares estiveram presentes em menor freqüência. Conclusões: 1. O modelo experimental, em suínos, desenvolvido viabilizou o estudo do Refluxo Gastroesofágico através da Pressão de Vazão Gástrica e Volume de Vazão Gástrico; 2. O implante de PMMA, no presente estudo, aumentou a Pressão de Vazão e o Volume de Vazão Gástricos, mas não a Pressão Basal do EEI, nem tampouco aumentou o seu comprimento; 3. Depósito de PMMA implantado e evidência de processo inflamatório crônico e reação tecidual de corpo estranho foi encontrada no local do implante de PMMA. Macrófagos com vacúolos intracelulares e fibrose foram encontrados com menos freqüência.
