The research intends to answer the following question: How is constitued a protagonist teacher in the Programa Ensino Integral, in order to initiate the implementation of a new educational model? The research participants are teachers working at E.E. Cora Coralina (fictitious name), a state school that joined the Programa Ensino Integral in 2014. The research’ corpus of analysis and interpretation was constituted from mixed questionnaires and semi-structured interview done with the educators working on the program. The research is qualitative and interpretive. It’s build by data triangulation, crossing the information collected from the program's teachers, the Guidelines for the Programa de Ensino Integral do Estado de São Paulo, the literature concerning to the implementation of new educational programs and the oficial documents about the improving processes offered to educators. The results show that the protagonista teacher improving processes offered to the teachers of the program until now wasn’t enought for the program’s requirements. According to the research’ participants, there were no teachers’ improvment offered specifically focused on the protagonism of teachers or related to concepts like leadership and educational autonomy. / O objetivo desta pesquisa é compreender o conceito de professor protagonista no Programa Ensino Integral (PEI) do Estado de São Paulo e verificar quais processos formativos foram oferecidos aos educadores do programa para se constituírem como protagonistas. A pesquisa procura responder a seguinte questão: como se constitui o professor protagonista no Programa Ensino Integral para iniciar a implementação de um novo modelo educacional? Os sujeitos da pesquisa são educadores que trabalham na EE Cora Coralina (nome fictício), escola estadual que aderiu ao Programa de Ensino Integral em 2014. O corpus de análise e interpretação da pesquisa foi constituído a partir de questionários mistos e entrevista semiestruturada feitos com os educadores atuantes no programa. A pesquisa é de natureza qualitativa interpretativa, feita por meio de triangulação de dados, cruzando os dados coletados junto aos educadores do programa, às Diretrizes do Programa Ensino Integral do Estado de São Paulo, os documentos oficiais de formação oferecidos aos educadores e a literatura referente à implementação de novos programas educacionais. Os resultados evidenciam que o conceito de professor protagonista e os processos formativos oferecidos aos educadores do programa voltados para o protagonismo do professor, estão aquém das exigências do programa. Até o presente momento, segundo os sujeitos da pesquisa, não foram ofertadas formações voltadas especificamente ao protagonismo dos professores ou que o relacionasse a conceitos como liderança e autonomia educacional.

Synthesis and Gas Transport Properties of Graphene Oxide Membranes

January 2018 (has links)
abstract: Graphene oxide membranes have shown promising gas separation characteristics specially for hydrogen that make them of interest for industrial applications. However, the gas transport mechanism for these membranes is unclear due to inconsistent permeation and separation results reported in literature. Graphene oxide membranes made by filtration, the most common synthesis method, contain wrinkles affecting their gas separation characteristics and the method itself is difficult to scale up. Moreover, the production of graphene oxide membranes with fine-tuned interlayer spacing for improved molecular separation is still a challenge. These unsolved issues will affect their potential impact on industrial gas separation applications. In this study, high quality graphene oxide membranes are synthesized on polyester track etch substrates by different deposition methods and characterized by XRD, SEM, AFM as well as single gas permeation and binary (H2/CO2) separation experiments. Membranes are made from large graphene oxide sheets of different sizes (33 and 17 micron) using vacuum filtration to shed more light on their transport mechanism. Membranes are made from dilute graphene oxide suspension by easily scalable spray coating technique to minimize extrinsic wrinkle formation. Finally, Brodie’s derived graphene oxide sheets were used to prepare membranes with narrow interlayer spacing to improve their (H2/CO2) separation performance. An inter-sheet and inner-sheet two-pathway model is proposed to explain the permeation and separation results of graphene oxide membranes obtained in this study. At room temperature, large gas molecules (CH4, N2, and CO2) permeate through inter-sheet pathway of the membranes, exhibiting Knudsen like diffusion characteristics, with the permeance for the small sheet membrane about twice that for the large sheet membrane. The small gases (H2 and He) exhibit much higher permeance, showing significant flow through an inner-sheet pathway, in addition to the flow through the inter-sheet pathway. Membranes prepared by spray coating offer gas characteristics similar to those made by filtration, however using dilute graphene oxide suspension in spray coating will help reduce the formation of extrinsic wrinkles which result in reduction in the porosity of the inter-sheet pathway where the transport of large gas molecules dominates. Brodie’s derived graphene oxide membranes showed overall low permeability and significant improvement in in H2/CO2 selectivity compared to membranes made using Hummers’ derived sheets due to smaller interlayer space height of Brodie’s sheets (~3 Å). / Dissertation/Thesis / Doctoral Dissertation Chemical Engineering 2018

Etude fonctionnelle de gènes régulés par le facteur de transcription CROWN ROOT LESS1 impliqués dans l’initiation et le développement des racines coronaires chez le riz / Functional characterization of genes regulated by the CROWN ROOT LESS 1 transcription factor involved in crown root initiation and development in rice

Gonin, Mathieu 23 November 2018 (has links)
Le but de cette thèse est de préciser les mécanismes moléculaires agissant en aval du facteur de transcription CROWN ROOT LESS 1 (CRL1) qui régule la formation des racines coronaires (RC). Nous avons pu identifier dans un premier temps une nouvelle séquence d’ADN reconnue par CRL1 nommé CRL1-box différente de la LBD-box qui était le seul motif cis-régulateur précédemment décrit pour la famille des facteurs de transcription (FT) de type LATERAL ORGAN BOUNDARIES DOMAIN (LBD). Nous avons ensuite identifié un groupe de gènes régulés par CRL1, et avons montré l’implication de deux d’entre eux, OsROP et OsbHLH044, dans le développement des RC. OsbHLH044 est un facteur de transcription répresseur et semble être aussi impliqué dans la sénescence cellulaire ainsi que la réponse aux stress. Enfin, nous avons mis en évidence une cascade de régulation liant positivement CRL1 avec QUIESCENT-CENTER-SPECIFIC HOMEOBOX (QHB) un gène impliqué dans la différenciation et le maintien du centre quiescent via le facteur de transcription OsHOX14. En addition nous avons mis en évidence une boucle de rétroaction négative de QHB sur ses activateurs CRL1 et OsHOX14, qui pourrait être impliquée dans la structuration du primordia de racine coronaire. / The aim of this thesis is to specify the molecular mechanisms acting downstream of the CROWN ROOT LESS 1 transcription factor (CRL1) that regulates coronary root (CR) formation. We were able to identify at first a new CRL1 recognized DNA sequence named CRL1-box different from the LBD-box which was the only cis-regulatory motif previously described for the LATERAL ORGAN BOUNDARIES DOMAIN (LBD) transcription factor (TF) family. We then identified a group of genes regulated by CRL1, and showed the involvement of two of them, OsROP and OsbHLH044, in the development of CR. OsbHLH044 is a repressive transcription factor and appears to be also involved in cell senescence as well as stress response. Finally, we demonstrated a regulatory cascade linking CRL1 with QUIESCENT-CENTER-SPECIFICHOMEOBOX (QHB), a gene involved in the differentiation and maintenance of the quiescent center, via the OsHOX14 transcription factor. In addition we have demonstrated a negative feedback loop of QHB on its activators CRL1 and OsHOX14, which could be involved in structuring the coronary root primordia

Vem ska göra vad? Uppdatering av arbetsfördelning : Förbättringsarbete på AB GotlandsHem / What task should be assigned to whom? Updating workload distribution

Lisper, Josefin, Aman Kylegård, Oscar January 2023 (has links)
Abstract Introduction: The case study has been conducted at AB GotlandsHem, the largest housing agency on the island of Gotland, Sweden. The study has two purposes. The first purpose is to map and examine the workload distribution in the inspection department by developing a generalizable template. The second purpose is to investigate how AB GotlandsHem can proceed with updating the workload distribution across all departments.   Problem description: Interviews have shown that several departments at AB GotlandsHem are experiencing unclarity about workload distribution. The workload distribution is uneven, unclear and unstructured, which leads to high workload. This can be seen in the long lead times at the inspection department.    Theory: Several theories have been used to analyze the study’s results. The theories being used are the cornerstone model, Kotter’s eight-step-model, workload distribution and Lean.    Method: The project was performed as a case study where an interview, observations, a diary and reviewing of existing documents was used. The collected data was analyzed by transcription, histogram and bar chart.   Results: The study’s results demonstrate that the developed template is effective. It further shows that the inspection department has significantly more actual hours then available hours, and several work activities within the department are irrelevant for them to perform. AB GotlandsHem consists of multiple sub-processes, each with a process leader responsible for the processes in the company.    Conclusion: The study reveals that most irrelevant activities can be moved to another process. If this relocation is implemented, the inspection department would reduce its actual hours and therefore decrease lead time since their available hours would be sufficient. Therefore, process leaders are responsible for reviewing work activities within their processes, allowing the company to map the departments irrelevant activities and the place more relevant for them.    Key words: cornerstone model, customer focus, inspection, lead times, process improvement, workload distribution    Fel!

Det första syftet är att kartlägga och undersöka arbetsfördelningen på besiktningsavdelningen genom att ta fram en generaliserbar mall. Det andra syftet är att undersöka hur AB GotlandsHem kan gå tillväga för att uppdatera arbetsfördelningen inom samtliga av organisationens avdelningar.   Problembeskrivning: Flera avdelningar inom AB GotlandsHem har vid intervjuer beskrivit oklarhet inom arbetsfördelningen. Arbetsfördelningen är ojämn, otydlig och ostrukturerad vilket kräver mer arbetstid än nödvändigt. Inom besiktningsavdelningen syns den otydliga arbetsfördelningen på de långa ledtiderna.   Teori: Flera teorier har använts för att analysera studiens resultat. De teorier som använts är hörnstensmodellen, Kotters åttastegsmodell, arbetsfördelning och Lean.   Metod: En kvalitativ fallstudie har genomförts och datainsamlingsmetoderna som använts är en intervju, observationer, en dagbok och dokumentgranskning. Data har analyserats med hjälp av transkribering, histogram och stolpdiagram.   Resultat: Studiens resultat visar på att mallen som tagits fram fungerar. Mallen har i sin tur visat att besiktningsavdelningen har många fler timmar faktiskt tid än disponibel tid, samt att flera arbetsaktiviteter inom avdelningen anses irrelevanta för dem att genomföra. Vidare har det kartlagts att AB GotlandsHem består av flera delprocesser som har varsin processledare som ansvarar för de processer som finns inom företaget.   Slutsatser: Studien visar att majoriteten av de irrelevanta aktiviteterna kan förflyttas till en annan process där aktiviteterna anses mer passande att utföra. Skulle förflyttningen genomföras skulle besiktningsavdelningen minska sina faktiska timmar och på det viset minska ledtiderna då deras disponibla timmar räcker till. Processledarna bör ansvara för att se över arbetsaktiviteterna inom sin process för att kartlägga avdelningarnas aktiviteter och avgöra om samtliga är relevanta för avdelningen.

Aide à la décision pour les entreprises industrielles inscrites dans une démarche de développement durable / Decision aiding for industrial companies in the context of sustainable development

Rizzon, Bastien 26 April 2016 (has links)
Le Développement Durable (DD) est « un développement qui répond aux besoins du présent sans compromettre la capacité des générations futures à répondre aux leurs. » Ses trois piliers fondateurs sont l’Economie, l’Environnement et la Société qu’il faut appréhender conjointement. Nous prenons le point de vue de la performance industrielle pour caractériser les besoins de l’entreprise dans une démarche DD. La performance industrielle, à travers son histoire, doit prendre en compte de plus en plus de critères jusqu'aux actuels piliers du DD. Nous proposons de voir le DD comme la démarche d'amélioration mise en place par l'entreprise. Dans ce sens nous proposons une aide au décideur humain qui permet de répondre aux exigences du DD et en particulier sa nature holistique et cyclique.Les entreprises déploient des approches d’amélioration continue à l’aide de standards et de méthodes comme le cycle PDCA. L’idée est alors d’enrichir cette pratique par un processus MCDA en aidant le décideur à formuler ses préférences et leur appliquer un traitement d’information adapté afin de fournir une aide à la décision qui serve la démarche d’amélioration. Pour intégrer l’imprécision dans la décision à prendre, nous proposons une méthodologie qui permet de caractériser la robustesse du résultat d’une méthode MCDA en fonction de l’imprécision des valeurs d’un critère. Pour prendre en compte l'aspect « réalisation opérationnelle » d'une action, en plus de son intérêt pour la performance de l'entreprise, nous avons développé un modèle de « faisabilité » associé aux actions en nous fondant sur la méthode ACUTA. L'idée est de proposer au décideur une information complémentaire à l'information d'utilité afin d'offrir une perspective autorisant un compromis Utilité/Faisabilité sur la décision à prendre. Nous déclinons notre proposition sur un cas pratique industriel mené dans le cadre d’une collaboration avec l’entreprise adixen Vacuum Products (aVP) d’Annecy. Ce partenariat a permis le déploiement de notre proposition pour un problème de décision portant sur les besoins d'instrumentation pour construire un système de management de l'énergie, conformément à la norme ISO 50001. / Sustainable Development (SD) is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." Its three founding pillars are Economy, Environment and Society which are to be handled together. We take the perspective of industrial performance in order to characterize the needs of a company involved in SD.Industrial performance, throughout its history, has to consider more and more numerous criteria up to the present SD pillars. We propose to look on SD as the improvement approach established by the company. According to this, we propose an aid for the human decision maker in order to fulfill the requirements of SD and notably its holistic and cyclic nature.Companies develop continuous approaches to improvement based on standards and methods like the PDCA cycle. Thus, the idea is to enrich this practice with a MCDA process for aiding the decision maker to establish his/her preference and to apply a suitable information processing to it that benefits the improvement approach. In order to integrate imprecision in the decision to be taken, we propose a methodology for characterizing the robustness of the product of a MCDA method in relation to the imprecision of a criterion value. In order to consider the aspect "operational implemantation" of an action, besides its benefit for the performance of the company, we developped a "Feasability" model related to the actions based on the ACUTA method. The idea is to offer the decision maker information complementary with utility information in order to permit a compromise Utility/Feasibility concerning the decision to be taken. Our proposition is applied to an industrial real case conducted in the framework of a partnership with the company adixen Vacuum Products (aVP) in Annecy. This partnership has led to the deployment of our proposition for a decision problem concerning the need in instrumentation required for the building of an energy management system, according to the ISO 50001 standard.

Kvalitetssäkring av kravställd dokumentation : En fallstudie utförd på Saab Dynamics / Quality assurance at document delivery

Nilsagård, Filippa, Lindholm, Sigrid January 2021 (has links)
Saab is a global company that primarily operates in the defense industry. The study is conducted at the Project office within the Development Department at Saab Dynamics. In a GAP analysis carried out by Saab Dynamics, one of the company's processes has proved to be unclear. The process that has been noted as problematic concerns how Saab Dynamics receives, reviews and approves and stores technical documentation that accompanies incoming deliveries. The study aims to clarify how the Development Department and the Purchasing Department collaborate on the work step and clarify how quality assurance of required documentation takes place in the current situation and how it can be improved. In the study, theory of total quality management, organizational theory as well as processes and Lean have been used. The case study has a qualitative approach as the focus aims to get a holistic view of the working methods on a specific process at Saab Dynamics that has been studied. The method used to collect data is documentation review and interviews of employees at the company. The result describes an unclear division of responsibilities regarding the work step between the Purchasing and Development Department and there is no clear process for quality assurance of required documentation. In order to have an efficient process, Saab Dynamics needs to eliminate the variation and waste that currently exists. Finally, an implementation proposal is presented for a standardized process for the work step.

Från ett vi och dem mot tillsammans : En studie om lärares upplevelse av skolkulturen och möjlighet till förändring genom aktionsforskning

Langfoss Dahl, Zara January 2020 (has links)
This study has an action research approach and is conducted as a part of an improvement process at the local school unit. The focus of the study is how the principal and the teachers at a public elementary school take an interest in the school culture and investigate how they can improve the practice while learn-ing from the process. The aim of the study is to create an understanding of the teachers’ experience of the school’s culture, and by using that as a basis, plan and conduct improvement schemes in the operations of the school. The results indicate that the theory of practice architectures enables the re-searcher to identify the sayings, doings and relating of the teachers. Moreover, the study has contributed to an understanding of what is enabled or prevented by internal and external conditions in the current process of action research and school development. The study shows that time and a common interest are central for uniting the college, which in turn is key if school development should lead to long-lasting improvement.

Ökad delaktighet för individen : Ett förbättringsarbete och en fallstudie om att införa ett systematiskt arbetssätt inom äldreomsorg / Increased participation of the individual : An improvement work and a case study introducing a systematic way of working in elderly care

Grönskog, Linda January 2022 (has links)
Förbättringsarbetet genomfördes i ett serviceområde med särskilt boende och hemtjänst inom kommunal äldreomsorg där upplevelsen var att arbetsmiljön hade brister och att arbetet för den äldre personens delaktighet hade behov av att utvecklas. Syftet med förbättringsarbetet och studien var att genom införandet av ett systematiskt arbetssätt för ökad delaktighet för den äldre personen, Individens behov i centrum (IBIC), att omsorgspersonalens arbetsmiljö skulle bli bättre samtidigt som den äldre personens delaktighet skulle förbättras.Förbättringsarbetet utgick från Nolans förbättringsmodell och genom SWOT-analys, Ishikawa diagram och en påverkansanalys utvecklades förståelsen för de utmaningar som fanns. Förbättringsarbetet innebar utbildning och ökad kunskap inom IBIC för omsorgspersonalen. Arbete med att upprätta genomförandeplaner med delaktighet för den äldre personens och dennes mål för sin insats pågår. I förbättringsarbetets del där den äldre personens delaktighet skulle granskas via genomförandeplanen kan än så länge inga förbättrade resultat synliggöras.Studien genomfördes som en fallstudie med en abduktiv ansats. Genom att följa omsorgspersonalens uppfattning om deras arbetsmiljö via fokusgruppsintervjuer och enkät kan slutsats dras att det finns tendenser till en förbättrad arbetsmiljö genom att arbeta med den äldre personens delaktighet och att utföra ett arbete som delvis kan följas systematiskt. / The improvement work was carried out in a nursing home and home care in municipal elderly care where the experience was that the work environment had shortcomings and that the work for the individual's participation needed to be developed. The purpose of the improvement work and the study was that through the introduction of a systematic way of working for increased participation for the individual, the individual's needs in the center (IBIC), that the care staff's work environment would be better while the individual's participation would be improved.The improvement work was based on Nolan's improvement model and through SWOT analysis, Ishikawa diagrams and an impact analysis, the understanding of the challenges that existed was developed. The improvement work meant training and increased knowledge within IBIC for the care staff. Work is underway to establish personal care plans with the participation of the individual and the individual's goals for their need of support. No positive results, this far, have been visible regarding this improvement work.The study was conducted as a case study with an abductive approach. By following the care staff´s perception of their work environment via focus group interviews and questionnaires, it can be concluded that there are tendencies towards an improved work environment by working with the older person´s participation and to perform a work that can be partially followed systematically.

Cartografiado de QTL y genes candidatos asociados a metabolitos determinantes de la calidad de fruto en melocotón

Sánchez, Gerardo 16 December 2013 (has links)
Tradicionalmente los programas de mejora del melocotón (Prunus persica (L.) Batsch) se centraron fundamentalmente en la obtención de genotipos elite de alta productividad, resistentes a plagas y patógenos, adaptados a diferentes zonas agroecológicas y que produzcan frutos de gran tamaño y buen aspecto. Como resultado, muchos de estos programas han obtenido cultivares de excelentes características agronómicas. No obstante, el mejoramiento selectivo hacia caracteres agronómicos puede ir en detrimento de la calidad organoléptica del fruto como fue demostrado en el caso de fresa y tomate donde algunos aromas se perdieron en el proceso de mejora (Klee and Giovannoni, 2011; Olbricht et al., 2008). En melocotón, la disminución de la calidad del fruto ha sido percibida por los consumidores y además es la mayor causa de insatisfacción de los mismos (Bruhn et al., 1991). Un probable consecuencia de esto puede ser el bajo consumo de melocotón en comparación con otras frutas como el plátano y la manzana (Crisosto, 2006). Estudios pioneros han establecido que el aroma es uno de los atributos principales por los cuales los consumidores juzgan la calidad del melocotón (Bruhn, 1995). El aroma está definido íntegramente por los compuestos volátiles orgánicos (VOCs) los cuales también contribuyen al sabor del fruto en combinación con azucares y ácidos orgánicos. Los volátiles del melocotón han sido estudiados con anterioridad, describiéndose un poco más de 100 compuestos incluyendo: lactonas, esteres, terpenos, aldehídos, ácidos carboxílicos y alcoholes entre otros [(Aubert and Milhet, 2007) y referencias incluidas]. La identificación de regiones génicas y genes candidatos para el control de los aromas del fruto resulta un punto fundamental para su posterior implementación en programas de mejora con el fin de obtener melocotones de mayor calidad. En este sentido nos propusimos la identificación de QTLs (del inglés ``Quantitative trait loci'') y genes candidatos involucrados en la producción de los compuestos volátiles del melocotón. El desarrollo reciente de un conjunto técnicas analíticas de mayor potencia permitió el advenimiento de una nueva plataforma tecnológica, la metabolómica, que contempla el análisis global de los metabolitos de un organismo permitiendo abordar la evaluación de calidad de una forma más exhaustiva. Dentro de ellas, la tecnología HS-SPME-GC-MS (del inglés ``Head Space-Solid Phase Microextraction-Gas Chromatography-Mass Spectroscopy'') es actualmente el método de elección para el análisis de volátiles debido a su alta sensibilidad, reproducibilidad y robustez (Tikunov et al., 2005). Además el análisis en conjunto de los datos derivados de la metabolómica con otras tecnologías de alto rendimiento para el análisis de expresión de genes, como lo son los microarrays, ha permitido el descubrimiento de genes implicados la producción de diversos metabolitos en Arabidopsis y tomate (Mounet et al., 2009; Saito and Matsuda, 2010; Carrera et al. 2012). En una primera instancia nos propusimos el desarrollo de una plataforma de alto rendimiento basada en HS-SPME-GC-MS para la identificación y cuantificación de compuestos volátiles en fruto de melocotón. Se ensayarán diferentes protocolos para la extracción de los compuestos volátiles con el fin de identificar el más adecuado (es decir el más sensible manteniendo la reproducibilidad y con una robustez satisfactoria). Una vez desarrollado un protocolo adecuado se analizará en paralelo la evolución de los compuestos volátiles y la expresión de genes mediante microarrays durante la maduración de diferentes genotipos de melocotón con el objetivo de identificar patrones comunes de co-regulación entre metabolitos y genes durante el desarrollo del fruto. Por último, se propuso la identificación de regiones génicas implicadas en la producción de volátiles mediante análisis de QTLs. / Sánchez, G. (2013).

Lean´s påverkan på arbetsmiljön : En kvalitativ studie över effekterna på arbetsmiljö och hälsa vid införande av Lean

Carlsson, August, Åqvist, Marcus January 2019 (has links)
There are many organizations that choose to introduce Lean production in their operations, as these are the concepts that have made the greatest progress in terms of efficiency programs. Since Lean focuses on maximizing customer benefit and minimizing waste of resources in an organisation's business processes, it is often forgotten that the introduction also affects the staff. The purpose of the study is to investigate what effects on the working environment and health that employees in the private sector experience after an introduction of Lean production as a strategy within their organization. The aim of the study has been to answer how a Lean introduction affects the working environment and health. The study is based on Almondy's latest improvement work on the shrinkage process. With the help of an interview study and a general literature study, we have examined what effects a Lean introduction has on the work environment and health. The interview study was conducted at Almondy AB, which is a food producer based in Gothenburg. Searching the literature is done in article databases with keywords linked to the area. By means of a comparative analysis method, the result has been analyzed. There are studies that show that the effects vary depending on the point of view they have had and in which industry the survey was conducted. This means that the effects get a large spread and therefore it is difficult to give a general picture of the effects. The results of the interview study show a positive effect on the work environment as they describe that the physical moments in the process have decreased. The results of the literature study show that more studies are needed to be able to demonstrate the general effects that Lean has on the working environment. But the literature study suggests that there are both negative and positive effects on the work environment and health when introducing Lean. The conclusion suggests that Almondy has had a positive impact on their physical work environment since there has been a decrease in deviation reports. If someone wants to study further in the field, Lean production should be investigated in several industries and examine all aspects of a Lean introduction linked work environment and health. / Det är många organisationer som väljer att införa Lean produktion i sin verksamhet, då det är de koncept som gjort störst framsteg när det gäller effektiviseringsprogram. Eftersom Lean fokuserar på att maximera kundnytta och minimera resursslöseri i en organisations verksamhetsprocesser, så glöms det ofta bort att införandet påverkar även personalen. Syftet med studien är att undersöka vilka effekter på arbetsmiljön och hälsa som anställda i den privat sektorn upplever efter införande av Lean produktion som strategi inom sin organisation. Målet med studien har varit att besvara hur ett Lean införande påverkar arbetsmiljö och hälsa. Undersökningen baseras på Almondys senaste förbättringsarbete av svinnprocessen. Med hjälp av en intervjustudie och en allmän litteraturstudie så har vi undersökt vilka effekter som ett Lean införande har på arbetsmiljön och hälsa. Intervjustudien är genomförd på Almondy AB som är en livsmedelsproducent stationerad i Göteborg. Sökning av litteraturen är gjord i artikeldatabaser med nyckelord kopplade till området. Genom en komparativ analys metod har sedan resultatet analyserats. Det finns studier som påvisar att effekterna varierar beroende på vilken synvinkel de haft samt i vilken bransch undersökningen gjorts. Detta gör att effekterna får en stor spridning och därför är det svårt ge en generell bild av effekterna. Resultatet från intervjustudien visar på en positiv effekt på arbetsmiljön då de beskriver att de fysiska momenten i processen samt avvikelserapporter har minskat. Resultatet från litteraturstudien visar på att det behövs fler studier för att kunna påvisa de generella effekterna Lean har på arbetsmiljön. Men litteraturstudien antyder att det finns både negativa och positiva effekter på arbetsmiljön och hälsa vid införande av Lean. Slutsatsen antyder på att Almondy har fått en positiv inverkan på deras fysiska arbetsmiljö då det har skett en minskning i avvikelserapporter. Om någon vill studera vidare inom området bör Lean produktion undersökas inom flera branscher samt granska alla aspekter av ett Lean införande kopplade arbetsmiljö och hälsa.
