Texto completo da fonteAlmost 80 % of all electric power is produced by steam turbine generators. That is why steam turbines have a massive role in our society today. Steam turbines are monitored with different measurement systems especially during startups and shutdowns. There are not many methods with which to monitor a thermal expansion of bearing pedestals of a steam turbine. For this type of monitoring the power company Fortum Power and Heat Oy uses the T-DAS measurement system which was originally developed for alignment measurement; to measure displacements of the pedestals caused by thermal expansion. Some problems have occurred in the measurements taken via T-DAS system previously. That is why Fortum wants to examine the performance of the measurement system. The primary goal of this master’s thesis was to find a correlation between results and the temperature around the measurement devices and seek a safe setting time for the system. Secondary object was to look for a replacement for T-DAS-system. The current measurement system was tested several times in different temperatures. Accuracy, precision, stability and linearity of the measurement system were examined with help of the statistical methods. According to research, the T-DAS system cannot measure accurately in certain power plant conditions. However it gives useful approximate results. The changing temperature and light pollution have effect on the results of measurements. The growing temperature of the measurement system affects heavily on its setting time. In the future, optical methods test-used in telemetering bridges may be applied to measure thermal growth of the pedestals

Texto completo da fonteThis thesis was completed in Kauhava, Finn-Power Oy, which is a part of the Prima Industrie Group’s machinery division called Prima Power. The aim of this thesis was to design compact, user-friendly and economical protection around a fiber laser to guarantee the machine’s safety and nonstop use. The protection of the fiber laser system is implemented in the current solution with protective wall elements, which takes up space, causes extra costs and prevents the user from getting to the brush table during machining. At the beginning of the process the features and risks of the laser beam were studied; the function and components of the lasers were also examined carefully so that every aspect would be considered in the design. In this thesis the aim was to calculate the necessary safety distances and permitted power densities and to consider different sorts of protection options to the fiber laser radiation. The various kinds of dangers were sorted, also taking into consideration the demands of the laser protection standards. Computer-aided design software Solid Edge ST6 was used as a design aid. The usefulness of the different implementation alternatives were estimated from the perspectives of safety, functionality and costs. All in all, the compact protection method was the best solution. Based on this were all of the other possible options delimited. The protection was divided into passive and active protection, and an optimal solution was found for both. Passive protection was implemented with aramid brushes, which will be strategically set around the laser nozzle depending on the capacity of laser head. These brushes protect against beam radiation by providing flexible, sustainable and intensive protection. The control of the aramid brushes, also called active protection, was implemented with piezoresistive coating, which reacts very sensitively to air temperature changes. The coating is positioned between the aramid brushes and the nozzle of the laser, so that a fault condition can be detected as soon as possible. Protective components must meet the required criteria for the tests, so that protection can be used in the laser system. The tested sections include a wide range of brush tests, temperature sensor tests and whole laser system assembly tests. Finn-Power, its component suppliers and partners are together responsible for these tests. As a result of the thesis a protection system for the fiber laser was produced. The final design is determined by different test results. Aramid is an excellent material as a radiation protector due to its mechanical and thermal properties. Because brushes are a critical part of protection, there must be wide range of tests so that the design would be optimal

Texto completo da fonteIn Finland water supply networks are deteriorating and the need to renovate them is growing. However renovations are not executed as much as is required. Current practices are not sufficient to fill the gap between the need for renovation and the renovation work that is carried out. In previous studies area based renovation model is one of the renovation models that has come up. In area based renovation the contractor is given an area which is renovated in accordance with standards specified in the contract. The aim of this work was to create a model of the procurement of area based renovation for water network. For the procurement model procurement procedures were selected and procurement documents were developed. Literature studies were carried out to research other countries procurement methods and a visit was made to the Danish waterworks to explore their renovation models. Competitive dialogue was recommended to be the procurement procedure in which the pre-selection is used to select the suppliers for the negotiations. The starting point was that the contractor performs all the work and part of the risks are transferred to the contractor. The contractor was to be given more freedom to fit the work into his schedule so the model assumes the contract period to be longer than in the conventional renovation contracts. Quality assurance was one of the themes of this work which was to be paid special attention. In all stages of procurement the quality assurance and verification were taken into account. The work is part of the development of area based renovation model for water network project carried out by WSP. The project involves six water companies: HS-Vesi Oy, Jyväskylän Energia Oy, Kouvolan Vesi, Kymen Vesi Oy, Porvoon vesi and Riihimäen Vesi. The model developed in the project will be specified when it is used in pilot areas of the water companies. The experiences of the renovation of pilot projects are not included in this work. Further studies are needed to analyze and report the experiences of the model in the pilot areas

Texto completo da fonteRoad dust causes problems in areas where the sand and salt are used to prevent slipperiness in winter. The dust causes health hazard and surroundings get dirty in the spring. The sand wears the road surface and it is also be crushed to smaller particles. The salt increases the wearing of the road because it keeps the surface longer wet. Also using studded tires increases the wearing of the asphalt. Some particles of the road dust are from burning processes, some are from distant sources and some particles are made by corrosion and mechanical wearing. These particles are reabsorbed up in the air by the tires or by airflow. It is possible to reduce road dust problems by using sweepers or other road maintenance equipments. It has been estimated that 50…70 % of used sand is collected every spring. The rest of sand is transported with snow or brushed to the side of the road. The collecting of the sand also lifts particles up in the air. The best way to prevent this is using water. But when using it must the temperature be above zero. To prevent dusting is also possible to use chemicals or vacuum. Before using those methods it is vital to design good housing, because it also improves their efficiency

Texto completo da fonteThe main campus of Oulu University of Applied Sciences will move to Linnanmaa in 2020. Due to the move of the main campus there will be about 20 000 people studying and working in Linnanmaa campus in the near future. Moving the main campus of Oulu University of Applied Sciences to other side of the city will change the demand of the public transport and requires developing of the public transport access. In this Master’s thesis new routes for public transport are searched. Goal for those new routes is to answer the growing demand of Linnanmaa’s public transport. This Master’s thesis consists of theoretical part and actual study. Study was made using Geographic Information Systems and Emme software for traffic and transit assignments. In this Master’s thesis Emme software is used to examine new public transport routes to Linnanmaa campus from three different areas. Areas which potential is studied in this Master’s thesis are Kempele, Toppila and Hiukkavaara. The main reason why public transport isn’t used when commuting to Linnamaa campus is because it is slow. One of the main competitiveness factors of public transport is its speed. The main reason why public transport isn’t suited for student’s trips to Linnanmaa campus is because of the crowded buses. The goal of the new routes studied in this thesis is to speed the travel time and offer routes that bypass the city center of Oulu. Bypassing the city center will shorten the travel time and also makes the busses between city center and Linnanmaa less crowded. Development of land use is taken into consideration while planning the new routes and searching potential areas that could have enough demand for new route to Linnanmaa. The highway through Oulu is improved and new bus stops will be built on the ramps of the highway. Surveyed routes from Kempele and Hiukkavaara will partly exploit the highway and the new bus stops. How the new routes effect on the travel time and on the number of the passengers is tested with Emme software. The most potential route is chosen from all three areas and as a result of this Master’s thesis, proposal of the new, improved public transport route network will be presented. As a result of the new improved public transport route network it was founded that travel time can be shorten from a wide area with one route that travels on highway and uses the new bus stops. Because of the shortened travel time also number of passengers will increase in a wide area. With the improved public transport route network, it is possible to improve the accessibility of Linnanmaa campus and offer more routes that can compete with car especially from Kempele. Results of this Master’s thesis cannot be directly generalized because the study was made with Emme software that is based on traffic in Oulu. Basic principles of this study can be exploited in other cities with their own traffic models. City of Oulu can exploit the results of this thesis in order to improve the public transport

Texto completo da fonteThe aim of this thesis was to examine what measures could be used to develop the environmental management of real estate maintenance. Part of the ISO 14001-2015 environmental management system standard was one aspect of this thesis. The property management industry has developed strongly in recent years and this brings challenges to management and environmental management. Most of the work is strongly related to a living environment such as people’s homes and property owned by them. The daily work associated with the field is visible and the operations of real estate maintenance must be a very clear and positive image creating activity through the public image. In the near future, the demands from customers and demands of employees’ knowledge will increase. Consequently, there is a need for clear guidance on the development of environmental management, since the related issues are significant in our lives. Property maintenance companies have and will continue to face major challenges in creating new operating models and familiarizing them to their employees. This work also seeks to focus on these areas. The property management sector has recently grown rapidly, for example outsourcing is increasing by the state and municipalities. Creating an environmental management system also raises the confidence of the authorities and all stakeholders in the company’s business and believes that the company is capable of delivering contracted services. Much research was also involved in the work in terms of legislation. In addition, efforts have been made to look into the future changes in the law and their expected impacts on environmental requirements. The demands of stakeholders have also been considered and evaluated what they might be in the future. To these requirements, the development of the environmental management system for real estate maintenance has already added things that are not necessarily available in the industry in general. They will possibly help the company to have a better environmental concern than competitors and other operators in the same field. This gives the company clearly better able to compete in national biddings. As a result of this work, the real estate industry and companies in the real estate sector in general have the tools ready to set up an environmental management system, which can in practice be directly certified by an accredited actor. The construction of the environmental system is a very challenging task for all companies, requiring a wealth of resources and a critical evaluation of the company’s operating methods. This work is a clear and direct guide to the real estate industry to develop an existing environmental management system or to create a completely new system. The work also clearly outlines risk mapping measures and prepared tables in job appendices that can be used to create own environmental management system

Texto completo da fonteThe aim of the thesis was to develop the use of BIM-based tools in tendering process in railway projects. The thesis was made for Destia Oy, and a literature study and interviews were conducted and also the BIM-based tendering was tested on the tendering phase of two railway projects. As a result an operation model was created for BIM-based railway tendering. In the interviews, Destia Oy’s tender chiefs were interviewed about the current situation, problems and needs of tendering process. BIM-based tendering was tested with Tilos program on the task scheduling and cost and resource calculation on two railway projects. Some of Destia Oy’s tendering staff were given training on the use of Tilos and they were interviewed on the operating model and program itself. The operations model describes the software tools used, the hierarchy between the programs and the information flows between different programs and tasks. By comparing the current tendering operation model with the new BIM-based operation model for tendering, the changes and benefits of moving to BIM-based tendering became visible. Based on the results, the tendering process in Destia Oy’s railway projects works well, even though the operation model is not the same for all the fields of Destia Oy’s construction. In tendering, there is a need for visual and feature-rich program tools for scheduling the tasks and also calculating costs and resources for tasks. BIM-based tendering allows for a more accurate scheduling and calculation of costs, and hence a more accurate bid. Based on the results, time-location charts utilizing BIM-based data for tendering can be recommended to the linear construction projects such as railway projects as well as for other construction projects

Texto completo da fonteThe goal of this master’s thesis was to develop the model-based process and information transfer of fairway and dredging projects. The first specific objective was to test the earlier made definition of as-planned model in dredging machine monitoring systems. Based on this test the goal was to update the first definition of as planned model. The second specific objective was to examine the development possibilities of model-based quality management in dredging industry. The first definition of as-planned model was tested at the dredging of West Harbour in Helsinki. For the machine monitoring test was created a 3D triangle mesh surface model that defined the target level of polluted clay removal. When defining the model-based quality management in dredging the model-based quality management instruction for road and street construction was used for basis and comparison. Information was also collected from the subscribers and contractors to back up the as-built model definition. Addition to as-built model definition the information contents maintenance material was generally defined. In the machine monitoring test the as-planned definition was detected to work functional. Machine monitoring worked flawlessly as planned. The need for improvement was though detected in the naming of the conveyable files. In the original as-planned definition the as-planned data meant all the data needed for execution. To clarify naming in the future it’s suggested that as-planned model only consists of the structural surfaces of the fairway or harbour. The rest of the model-based and other materials should be named as as-planned material. It was detected that when naming the as-built model the same rules should be followed as when naming the as-planned model. At road and railway construction as-built model is at this moment defined as a design model which is corrected with the design mistake. At the dredging industry this is not accurate and overall as-built model is defined as the actualized seafloor model detected by Multibeam acoustic surveying. The as built materials should consists of as-built model, detected soil type information, boulder information, the locations of blasted areas, experiential information and other files. The maintenance material is needed when up keeping the fairways and as start-up information for later dredging works in the same area. Maintenance material consists of the seafloor model detected by Multibeam acoustic surveying, soil type information, boulder information, the locations of blasted areas and experiential information. Advanced dredging contractors are able to use their existing systems and know-how to for utilizing information models proficiently and effectively. The subscribers’ needs and opportunities in the model-based execution should be developed further for example using a suitable cloud service. Echo sounded as-built models can be stored in to existing registries of the subscriber but there were founded different development possibilities

Texto completo da fonteHospitals are facing pressure to improve their operations and the efficiency of their processes. Operating theatres and hospital’s logistics activities are among the largest cost areas in hospital’s budget. This paper aims to suggest improvement areas in Oulu University Hospital’s (OYS) operating theatre material logistics. One of the desired outcomes was to link material logistics to be part of the operating process. In the beginning of the research, a literature review was performed around the topics of process modelling and the suitability of Lean methodology in the health care environment. Furthermore, literature was used to get a better understanding of operating room scheduling and the sterilization department processes. There are various tools, which can be used for process modelling. Flowcharts are especially suitable for understanding the overall process, according to the performed literature review. One application of flowcharts is Lean’s Value Stream Mapping (VSM) tool, which can be categorized to the holistic supply-chain optimization methods. Lean has received recognition in the health care industry, since the early 2000s. When applied to the hospital environment, the VSM tool has often been partly modified. In the analysis phase several different tools and premises can also be applied. As a unifying factor you can recognize the aim to remove sources of waste from the process. Lean’s (VSM) tool was chosen to be used as the process modelling tool in the empirical phase of this paper. The performed VSM focused on one product family: TEP-surgery process also known as total endoprosthesis. There are various nuances of VSM tool, and so as the more specific mapping tool Henrique et al.’s (2015) application was chosen to be used. It covers the patient flow, information flow and material flow each on its own separate line. The initial current state map was constructed with the help of interviews and perception. Next the current state map was filled with data that was gathered from patient information system anonymously and it was sent out alongside with a questionnaire to the participants of the workshop. Fifteen professionals participated in the value steam mapping workshop. They participated on validating of the current state map and they recognized further challenges from the current process. Later in the workshop the group was divided into smaller teams in which the participants would try to come up with a solution to a problem. Hereafter, a step back was taken to the principles of Lean and the improvement areas and sources of waste were prioritized by the need of the end customer. Fast and high-quality treatment was assumed to be the most important value of the customer. Based on this assumption the value stream of procedure package was also modelled with Process Activity Mapping tool. As the result of this research four improvement areas were regocnized in the material flow, which are the maintenance process in sterilization department, the location of the sterilization department underneath the operating theatre, tackling the material needs during an operation with a dedicated employee next to the operating room or with larger inventory inside the operating room and lastly more active follow of the demand and planning of the available capacity. Although the research focused on one product family the results can be utilized in most operating processes of OYS. The main risk of the suggested actions is the waste of excess inventory

Texto completo da fonteThere are nowadays constructed more often reinforced concrete bridges than composite bridges in Finland. The aim of this master’s thesis is to develop structural solutions and construction method of composite bridges in order to be able to improve competitiveness of the composite bridges. The study scrutinizes different types of composite bridges and cost information related to bridge fabrication. The research includes comparisons between the fabrication costs of a plate girder and an airtight box girder and also between different types of bridge deck structures. The goal is to find a technically and economically optimized bridge solution. Kapsajoki Bridge, located in Kittilä, has been used as a case study. The bridge is two-span composite bridge and consists of two main girders. The span lengths are 20,8 + 20,8 m and the effective width is 7,5 m. Fabrication costs of the composite bridges have been calculated using the average Finnish workshop capacities and prices. The overall cost estimates of the bridges are based on cost information provided by the Finnish Road Administration (nowadays Finnish Transport Agency). The cost of deck elements and stay-in-place casting moulds have been calculated using general Finnish unit prices of deck elements and based on the cost information defined in Riitaoja’s (2009) master’s thesis. Deck elements are fabricated on the concrete plant and stay-in-placce casting moulds consist of corrugated sheets and thin-shell slabs. Based on calculated results, the overall cost estimates, fabrication costs and steel grade costs of the airtight box girder seem to be competitiveness. However, plate girders, which have fabricated of weathering steel, have respectively smaller costs than airtight box girders. The biggest difference between those two girders is the separation of the painting area of the girders. The painted surface area of airtight box girders is proved to be significantly smaller than the area in plate girders. Deck elements are much more expensive in comparison to stay-in-place casting moulds. However, rapid and easy erection of those elements allow savings in construction time and falsework. That’s why deck elements should be taken into consideration. The calculated results indicate that the cheapest way to build the bridge deck is to use corrugated sheets, which are installed on the top of the flanges of the main girders. At least every edge beams of those stay-in-place casting mould alternatives need to be constructed using falsework and supporting structures. Assembling and disassembling of falsework and supporting structures will slow down the construction work. Based on the results of this study the most technically and economically optimized girder and deck solution proved to be weathering steel plate girders and corrugated sheets on top of the flanges of the main girders. However, it’s good to keep in mind that results and structural solutions of the research vary from case to case

Texto completo da fonteThe target set to the work was to develop open data transfer for bridge information modeling. Open data transfer was studied with aim to develop software-independent solution to produce contents of design data for separate design stages and data transfer between stages from initial data to engineering design made for construction. Open data transfer was tested for several model based bridge design, where most of the projects were for engineering design but there was also basic design bridge projects. In some cases the design process covered basic design, engineering design and also product model transfer to the contract. Information of the technical bridge structures and other infrastructure refer to the bridge is able to produce using open data formats, which are IFC and Inframodel. By IFC format it is possible to produce adequate information to the bridge engineering design, although IFC is not including bridge-specific entities. The IFC-Bridge extension of IFC standard under development would eliminate major part of the lack and would offer new changes especially to the parametric modeling of the bridge geometry. In information modeling based design the model and the design documents produced based on information in the model includes almost all of the information set in requirements by bridge design manuals and guidelines. Open standard based data transfer eliminates many problematic cases of intellectual property rights (IPR) but at the same weaken usability of the data during next design stages. However it is reasonable to switch to use the open data exchange because if provides means to transfer data in standard mode and independent from software. For software used in bridge and infra engineering design stages there are still limited possibilities to execute data transfer using open data formats between different technical design areas. Therefore it is reasonable yet to use also open geometry formats alongside with open data formats, as well as native formats if intellectual property rights are taken into consideration

Texto completo da fonteThe aim of this thesis is to further improve electrical control of a hyperspectral drill core scanner. The improvements are targeted to sharpen the quality of scanning as well as automating previously manually done work stages. The research was considered necessary as the current scanning system is prone to time consuming problems. The highest priority is to design simple and speed-wise stable system for drill core scanner. The basics of hyperspectral imaging and drill core logging as well as main features of automated systems are discussed in the theory part of this thesis. Also most commonly used linear gears in automated systems are presented in this paper. Linear gears convert rotational motion into linear motion. A brief summary of how the current generation hyperspectral scanner works and what problems it has and suggestions on how to solve them are studied. Significant amounts of information about servo system’s suitability for constant speed application such as the hyperspectral drill core scanner has been achieved as a result of this study. The information will be helpful for the scanner discussed in this paper and all future scanner applications designed by Specim Ltd. The use range of the scanner was expanded substantially by using the servo system and the typical stepper motor resonance effect was eliminated. Expanded use range allows slower scanning speeds which creates opportunities for future scanner applications. The movement of hyperspectral cameras in horizontal and vertical directions can be done accurately with stepper motors. The movement to the correct position can be easily calculated by using the camera’s field of view and sample’s width. All cameras can also be moved simultaneously. These measures will reduce the setting time of the scanner and result in a higher utilization rate

Texto completo da fonteThe objective of this thesis was to develop vibration design procedures of pedestrian bridges. Nowadays, it is possible to build slimmer, lighter and, by structural design, more versatile structures. The current design standards have become outdated on this matter and needlessly restrain some desired structural solutions. In this thesis, the design procedures were improved in conjunction with the development process of Eurocode standards EN 1990 and 1991-2. The analysis was carried out from the practical viewpoint by comparing the results obtained in different design situations using various pedestrian load models. In particular, a sensitivity analysis was performed to study the influence of uncertainties of the design parameters to vibration calculations. One goal was also to clarify the design process and ease the communication between the client and the structural designers. Improvements to the structural models and load models used in vibration design and composition of the standard text were proposed. Guidelines for assessing the design situation and comfort levels were given in order to improve the client-designer communication. Also, guidelines concerning different phases of the design procedure were given to structural designers

Texto completo da fonteElectronics is a constantly developing technological area. New solutions are needed to make production, processing and distribution of information more efficient. Besides developing and improving the old products, completely new products and solutions are pursued to discover. A printed electronic on flexible plastic substrate is an example of that type of products. The aim of this master’s thesis was to design and build a test system for reliability testing of printed electronics. Manufacturing methods of printed electronics have effects on reliability properties thus getting familiarized with different manufacturing methods is required. More specific familiarization of printed electronics’ manufacturing methods focuses on typically used screen printing. The test system was designed according to a test plan, which is created according to standards related to reliability testing. Test plan included three different tests: bending- torsion- and stretching strain tests. Test plan was created to ensure that the test system will be functioning accurately enough and that the results given from system are reliable. Datasheets for connectors of glass laminated test samples from “Flex-in-glass” -project were also utilized in design process to ensure sufficiently strong structure and mechanical stability for test system. Finally, test system was tested with test measurement. Samples used in measurement were PET (Polyethylene terephthalate) film which had a conducting ITO (Indium tin oxide) coating on the other surface. The operation of test system was evaluated according to resistance results from test measurement. According to test measurement results, test system works according to its demands and it can be used for reliability testing it is designed for

Texto completo da fonteTiivistelmä Tutkimuksessa kehitetään ja arvioidaan tietojärjestelmään soveltuva potilaan ja hänen läheistensä hoitotyötä kuvaava tehohoitotyön malli toimintatutkimuksen lähestymistapaa noudattaen vuosina 1997-2001. Tutkimusyhteisöinä toimivat Oulun yliopistollisen sairaalan päivystysalueen, postoperatiivinen ja sisätautien teho-osastot. Tutkimuksen I-vaiheessa kehitettiin ja esitestattiin tehohoitotyön malli keräämällä tutkimusaineisto kyselylomakkeen avulla toimintatutkimusryhmään osallistuneilta hoitajilta (N = 14), toimintatutkimusryhmästä muodostettujen pienryhmien ja toimintatutkimusryhmän tuottamista kirjallisista aineistoista (N = 33), äänittämällä raporttitilanteita (N = 57) ja tutkijan kirjallisista muistiinpanoista. Esitestausaineisto kerättiin lomakkeella hoitotyön dokumenteista (N = 17) ja kyselylomakkeella hoitajilta (N = 11). Tutkimusaineistot analysoitiin induktiivisella ja deduktiivisella sisällönanalyysillä. II-vaiheessa yhteensovitettiin malli tehotietojärjestelmään. III-vaiheessa arvioitiin mallin luotettavuutta päivystysalueen ja postoperatiivisen osaston tietojärjestelmästä kerätyn potilasaineiston (N = 1464) ja tutkijan arkistoitujen potilasasiakirjojen (N = 30) analyysien avulla. Potilaiden hoitoisuutta ja hoitohenkilökunnan määrällistä tarvetta verrattiin tehohoitotyön mallin ja Therapeutic Intervention Scoring System-luokituksen (TISS) kesken tietojärjestelmästä kerätyn päivystysalueen (N = 253) ja postoperatiivisen (N = 579) teho-osaston potilasaineiston perusteella. Tutkimusaineisto analysoitiin tilastollisin menetelmin ja sisällönanalyysin avulla. Tehohoitotyön malli kuvaa potilaan elintoimintojen muutoksiin, sairauden ja sen hoidon tuomiin rajoituksiin ja kokemuksiin sekä läheisten hätään liittyviä hoitotyön diagnooseja, terveysongelmien vaikeusasteita vastaavaa hoitotyötä, hoitotyön toimintoja ja hoitotyön tuloksia sekä hoitoisuutta. Luotettavuustutkimuksen mukaan malli erotteli tulotyypiltään ja sairauden vaikeusasteiltaan erilaisten potilaiden hoitotyötä (p < 0.001). Mallin avulla voitiin kuvata hyvin potilaiden kuoleman riskiä (ROC 0.86-0.91). Malli antoi suuremmat hoitoisuuspisteet ja henkilökunnan määrällisen tarpeen päinvastoin kuin TISS potilaille, jotka olivat tulovaiheessa sairaampia ja joiden hoitoaika oli pitkä ja kuolleisuus suuri. Mallia voidaan käyttää lähtökohtana näyttöön perustuvan keskitason teorian kehittämiseen, jolla voidaan antaa perusteet osoittaa tehohoitotyön vaikuttavuutta potilaan kokonaishoidossa

Texto completo da fonteTiivistelmä Tutkimus oli kaksivaiheinen. Ensimmäisen vaiheen tarkoituksena oli kuvailla ja selittää ohjauksen laatua potilaiden ja hoitohenkilöstön arvioimana. Tutkimuksen toisen vaiheen tarkoituksena oli määritellä ohjaus-käsite ja testata käsitteen rakenne. Tutkimuksen ensimmäisen vaiheen aineisto kerättiin tätä tutkimusta varten kehitetyillä mittareilla postikyselynä Oulun yliopistollisen sairaalan potilailta (n = 844) ja hoitohenkilöstöltä (n = 916). Aineiston analyysissä käytettiin perus- ja monimuuttujamenetelmiä sekä sisällönanalyysiä. Tulokset tuottivat jatkotutkimusaiheen tutkimuksen toiseen vaiheeseen. Tutkimuksen toisessa vaiheessa ohjaus-käsite määriteltiin käsiteanalyysillä, jonka aineisto kerättiin harkinnanvaraisesti Medline-, Cinahl- ja Medic-tietokannoista (n = 32) ja käsihakuina yleisteoksista (n = 6). Aineisto analysoitiin induktiivisella sisällönanalyysillä. Analyysin tuloksena määriteltiin ohjaus-käsite. Teoreettisen käsitteenmuodostuksen jälkeen ohjaus-käsitteen rakenne testattiin konfirmatorisella faktorianalyysillä. Aineistona käytettiin tutkimuksen ensimmäisen vaiheen aineistoa (n=844). Tutkimuksen ensimmäisen ja toisen vaiheen tulokset yhdistettiin ohjauksen laadun hypoteettiseksi malliksi. Ohjauksen resurssit olivat kohtalaiset, mutta ohjausaika oli riittämätöntä. Hoitohenkilöstön tiedot ja taidot ohjata olivat kohtalaisen hyvät. Potilaiden mielestä hoitohenkilöstön asenteet olivat osittain kielteisiä, vaikka hoitohenkilöstö piti niitä myönteisinä. Ohjausmenetelmistä hoitohenkilöstö hallitsi hyvin vain suullisen yksilöohjauksen. Kolmannes potilaista ei saanut kirjallista ohjausmateriaalia lainkaan. Lisäksi viidennes potilaista arvioi, ettei ohjaustoiminta ollut potilaslähtöistä. Ohjauksen suunnittelussa ja arvioinnissa ei aina otettu potilaan taustatekijöitä huomioon. Vuorovaikutus toteutui hyvin. Ohjaus oli kuitenkin osittain riittämätöntä varsinkin ennen sairaalaan tuloa sairauteen ja sen hoitoon liittyvien asioiden osalta sekä sairaala-aikana sosiaalisen tuen osalta. Potilaslähtöinen ohjaustoiminta, ohjauksen riittävyys ja kokonaislaatu selittivät ohjauksen vaikutuksia. Ohjauksella oli vähän tai ei lainkaan vaikutusta kolmannekseen potilaista. Vähiten ohjaus vaikutti omaisten tiedonsaantiin. Kokonaisuudessaan potilaat pitivät ohjauksen laatua hyvänä. Ohjaus määriteltiin potilaan ja hoitohenkilöstön kontekstiin eli taustatekijöihin sidoksissa olevaksi, vuorovaikutussuhteessa rakentuvaksi, aktiiviseksi ja tavoitteelliseksi toiminnaksi. Ohjauksen lähtökohtana on potilaan ja hoitohenkilöstön konteksti, jonka kohtaaminen edellyttää vuorovaikutukselta kaksisuuntaisuutta. Vuorovaikutus on keino, jolla ohjaussuhdetta rakennetaan. Onnistunut vuorovaikutteinen ohjaussuhde mahdollistaa potilaan ja hoitohenkilöstön välisen aktiivisen ja tavoitteellisen toiminnan. Kehitetyn hypoteettisen mallin mukaan ohjauksen laadulla tarkoitettiin sitä, että ohjaus on hoitohenkilöstön ammatilliseen vastuuseen perustuvaa, potilaan ja hoitohenkilöstön kontekstiin eli taustatekijöihin sidoksissa olevaa, vuorovaikutussuhteessa rakentuvaa, aktiivista ja tavoitteellista toimintaa, joka on asianmukaisin resurssein toteutettua, riittävää ja vaikuttavaa. Tutkimustuloksia voidaan hyödyntää ohjauksen teorianmuodostuksessa, ohjauksen laadun kehittämisessä sekä hoitotyön perus- ja täydennyskoulutuksessa

Texto completo da fonteCompanies need to improve their business processes so as improve to and maintain their competitiveness. The importance of supply has become a significance issue in modern business world. Nowadays efficiency and innovations are meaningful factors to maintain the competitiveness. The aim of this Master’s Thesis is to clarify how to improve the efficiency of the case company’s supply chain. Construction business is often criticized about poor quality and excessiveness of standardization, which do not respond a versatility of customer demand. The construction industry is usually behind many other sectors in its development of production and supply chain. Construction industry utilizes the business process re-engineering method in its development, which aims at better efficiency, quality and capacity to offer bigger product supply for markets. Also industrialized production is tried to implement in field to achieve better delivery cycle, quality and cost efficiency. According to this research the biggest problem in the delivery cycle of supply chain is long waiting times between different functions. The aim is to find critical time points and factors, which are generating waste of time in the process. Attention is paid also to elimination of these problem factors. This research is done in case company, which products domestic houses in Finland. The aim was to create new operation model, which shortens the delivery cycle of orders. The re-engineering of supply chain bases on process management. This Master’s Thesis is a qualitative study about re-engineering and modelling of the business processes. In qualitative research was exploited interviews, workshop, process modelling and case company’s information systems in studying the order book. Fieldwork and observing participation are important work methods in qualitative research. These were also applied in this research. Waste time was generated between almost every function in the process. The main problem was poor documentation in handling of orders, which causes difficulties in the whole supply chain. Therefore, development of the receipt process of orders was taken as focus in re-engineering the supply chain. The second development need was the development of the design department for standardization of the products. Also in this case the decisive issue was to increase the systematic documentation and information systems in handling the orders. The case company made organizational and operational changes in its processes. The delivery cycle time in construction business is longer than in many other industries. An experimental research was made on the basis of the order book in spring 2014. This study indicated that delivery cycle can be improved with orders handled by new operational model. The delivery cycle has not yet achieved the desired level, but utilizing the production methods of the industrialized production, for example standardization of the products, it is possible to achieve significant improvements in the delivery cycle time. The results give strong evidence that by re-engineering of the supply chain in the case company efficiency and shorter delivery cycle can be achieved. This also leads to better cost efficiency

Texto completo da fonteThe aim of this master’s thesis was to develop a dynamic management method for an information model-based railway earth mowing work. The primary target was to develop a process model about an information model-based dynamic management method and research the possibilities to use the existing commercial applications as a management tools. Inframodel3- data transfer format’s features and improvement needs was studied from dynamic management method’s perspective. Characteristics of railway construction and improvement needs caused by information model-based actions were studied by literature research and observing an information model-based railway construction site. The current challenges and issues that need to be improved in current management method were discovered and gathered, by researching the current management method and performing an interview to the personnel of the construction site, software producers and other project partners at the railway construction site. Principles of the dynamic management method were studied through literature research and based on findings a process model for information model-based railway earth moving work was developed. Features of the commercial applications and Inframodel3 data transfer format were studied by literature research and the usability of them in the dynamic management method was evaluated by handling and processing information model based data with the applications. The dynamic management method of an information model-based railway construction site means real-time and efficient reacting on impulses from construction site and construction site management that is comprehensive, communal and adaptable and utilizes information models. The efficiency of dynamic management method is based on real-time information used in management actions. This is enabled by gathering continuously real-time observations about the progress on the construction site. By construction site management’s efficient reacting on the incoming impulses from the construction site such as measurement results, production disruption and innovations, prevents the accumulation of potential problems to following operation steps and also enables continuous development of the construction process. According to the answers from interview survey and observations at the construction site the possibilities to develop the management method and construction processes with the help of information model-based actions has been recognized. In addition to better time schedule and resource management, realization and cost observation also efficiency, productivity and environmental friendliness were issues that wanted to developed with better information management and new information model-based tools. The commercial applications and Inframodel3 data transfer format tested on construction site did not fulfill all the dynamic management method’s demands considering the real-time realization reports, continuous quality assurance and management of resources, time schedule and costs. The information model-based railway construction site practices can be developed and the impacts of the implemented management measures can be observed in real-time through the dynamic management method. The collaborative and dynamic management method enables all employees to innovate and encourages them to develop all the site activities, by starting from their own tasks, leading to higher efficiency and quality of the entire construction project. Effective use of the dynamic management method at the information model-based construction site requires introduction and development of the new tools, which enables information model-based site activities as well as a real-time monitoring, quality assurance and control

Texto completo da fonteThe main aim of the thesis work was to develop a mechanically ventilated warm base floor structure for the single house. The work was also intended to find out that the developed new foundation construction works correctly according to the building physics and ensure the housing safety in the building with the warm base floor. The new mechanically ventilated warm base floor structure suitable for the prefabricated modular buildings was developed due to the problems with the common free ventilated base floor structure with a crawl space. In this construction insulation is moved from the floor structure towards the ground and the foundation wall. From this warm crawl space, ventilation is done mechanically through the heat recovery. In order to ensure the physical structure of the building field measurements were carried out in the nine different single house buildings. During the field measurements temperatures, humidity, radon, air microbe concentration and under pressure in the warm base floor space in the relation to the living space were measured. In addition, the air tightness measurements were made for the houseroom as well as the base floor crawl space. The long-term temperature and relative humidity measurements in these single house buildings under the experiment were free from the mold growth favorable environment in any season of the year. The pressure difference measurement between the warm base floor spaces and the living space shows that the warm base floor space was under pressure compared to the living space which prevents the diversion of harmful substances to the living space air. In this regards operation of the warm base floor structure is substantially improved compared to the traditional crawl space structure which is typically having the overpressure in the relation to the living space. The buildings radon concentrations in the living space were low and acceptable in all locations where measurements was done (≤ 30 Bq/m³). In the warm crawl space radon concentration was 110–460 Bq/m³ depends on the building under experiment. This indicates that the warm space floor structure together with the mechanical ventilation prevented excessive radon entry to the living room air. Air samples from the building under experiment shows that even the absence of microbial and bacterial concentrations in the air decreased when moving from the crawl space to the living space. Based on the field measurements warm base floor structure developed in this thesis work is functioning according to the building physics and it is clearly better than the traditional free ventilated crawl space base floor. Thus the structure can be safely used in the new buildings and there is potentiality to develop further

Texto completo da fonteThe subject of this thesis is NordDRG, a patient classification and productization system in use in Finland. Theory also covers actions related to productization of health care. Aim of this thesis is to describe the nature of coding patient information regarding productization and reimbursement in Vaasa Central Hospital. Information systems assistance to coding is also covered. This thesis aims to improve coding in Vaasa and thus suggests development activities to Vaasa Central Hospital. Thesis introduces a model by which patient data coding can be improved and controlled systematically. Firstly the basis of coding, productization and reimbursement is introduced. Theory explains the problem areas in coding and takes a stand on how it affects in productization on national and hospital’s internal scale. Theory part introduces the health care productization system NordDRG. Chapters related to patient data coding practices and NordDRG system reveal how productization can ideally work. For the empirical part semi-structured interviews were conducted in Vaasa Central Hospital health care units, finance and information technology departments and administration. Interview template consists of questionnaire about health care professionals coding practices and utilization of information technology. Empirical chapters also include statistical analysis of coding in all Finnish central hospitals. General understanding of Vaasa Central Hospital coding practices versus other Finnish central hospitals was created from interview and statistical analysis results. The most important findings of this thesis were the poor performance of coding in Vaasa by national standards, low utilization of coding results to improve coding and low overall utilization of NordDRG system capability. Nationally significant finding is the variation of coding practices between hospitals. The variability of coding levels has an impact on national productivity figures. In Vaasa coding practices vary greatly between different units and between coders of a single unit. Coding practices are manifold. There is also potential for improvement in information system design and development. Although those information systems that have a direct impact on NordDRG include the functions needed for total NordDRG classification. Nevertheless utilization of IT systems in coding is defective. The results can be generalized to greater proportion of departments in Vaasa. The development activities introduced in this thesis have a strong scientific basis and have proven to improve the level of coding. Introduced development activities are based on Six Sigma, also known as DMAIC, model. Process performance measurement and analysis plays a central part in development activity implementation through DMAIC model. Process measurement and statistical analysis according to DMAIC have been used successfully in other health care organizations. The essential activity is to measure diagnosis and procedure code occurrence within a single unit. Measurement results are analyzed with statistical process control methods. Success of implementations is monitored through continuous process measurement and analysis. Single important development activity is to shift the responsibility of high-quality coding to the health care units

Texto completo da fonteThe aim of this thesis was to standardize and refine the Eurocode guidelines for the design of pile caps. The specific focus is on the examination and refinement of the strut-and-tie method used for design of pile caps. The primary purpose of the thesis was to provide an Excel based sheet that can be used to design pile caps including from two to nine piles. Another goal was to compare the results of the calculation to values typically used for pile caps. The work was carried out in two phases. The first phase included the theoretical part of the work, in which the design of the pile caps and the strut-and-tie method was studied by means of a literature review. In the second phase of the work, the solutions defined in the first step were moved to the calculator. The calculator was designed on the basis that sought to create the most affordable solutions, yet comply with the Eurocode guidelines. The most important results of the thesis were in the effects of the permissible location deviations of the piles on the results obtained. The iterative calculation method used in the work enables more precise consideration of location deviations in the calculation results than the more commonly used calculation methods. This makes the strut-and-tie structure more realistic and no additional certainty for the durability of the structures is required. Additionally, the queries of the node defined in the work are more accurate than in the general calculation styles. The results of the work are utilized using the calculation sheet mentioned above. The calculation sheet accelerates and facilitates the design of pile caps and the consideration of constructional constraints. The calculator also allows a quick comparison of the results when given values change

Texto completo da fonteTiivistelmä Suomalaisessa yhteiskunnassa on viime vuosien aikana puhuttu ja kirjoitettu paljon siitä, että Suomen taloudellisen hyvinvoinnin ja talouskasvun perustana on tulevaisuudessa organisaatioiden uudistumis- ja innovaatiokyky. Kaupan esteiden vähentyminen "Kiina-ilmiöineen", kansainvälinen verokilpailu, EU:n kasvu- ja vakauttamissopimukset, korkea ikärakenne ja monet muut tekijät aiheuttavat kansallisen paineen olla kansainvälisen innovaatiokehityksen kärjessä. Kansainvälisessä kilpailussa korkean palkkatason kansantalous ja sen organisaatiot voivat menestyä markkinoilla vain innovoimalla - kehittämällä jatkuvasti entistä parempia tuotteita, menettelytapoja ja palvelua. Näistä tarpeista lähtien tutkimuksessa kehitettiin olemassa olevan teorian ja liikkeenjohdon oppien sekä empirian avulla "organisaation innovaatiokyvyn johtamismalli". Malli sisältää osaamisalueita, joihin panostamalla organisaatio voi parantaa innovaatiokykyään. Osaamisalueet ovat kumppanuus- ja sopimusyhteistyöosaaminen, verkostotaitojen osaaminen, innovatiivisen hankintaprosessin osaaminen ja innovaatiokannusteiden käytön osaaminen. Näitä kehittämällä organisaatiolla on entistä paremmat mahdollisuudet saavuttaa positiivista tuottavuuskehitystä ja hyötyä näin ollen aineettoman varallisuutensa kehittymisestä. Mallin avulla organisaatio pystyy kehittämään ja hallitsemaan innovaatiokykyään jatkuvan parantamisen filosofian mukaisesti. Johtamismalli sisältää mittausmenettelyt ja tutkimuksessa kehitetyt mittarit sekä näiden kytkennät organisaatioiden olemassa oleviin johtamisjärjestelmiin. Organisaatio voi myös verrata omaa innovaatiokykyään suhteessa muihin organisaatioihin ja hyödyntää tietoa oman organisaation johtamisessa ja motivaatioasetelmien rakentamisessa. Kehitettyä mallia testattiin ja arvioitiin suomalaisessa infra-alan toimintaympäristössä kuudella eri tavalla. Malli läpäisi suoritetut testit, ja arvioiden mukaan sitä voidaan hyödyntää kaikissa organisaatioissa niin julkisella alalla kuin yrityksissäkin. Yhtä lailla malli sopii käytettäväksi arvoketjun eri vaiheissa. Mallia ollaan ottamassa laajasti käyttöön ja kehitetty malli on organisaatioiden saatavilla Internetin kautta osoitteessa: http://www.innovaatiomittaus.fi. Teoreettista kontribuutiota saavutettiin ehkä eniten johtamismallin toimivuuden ansiosta. Teoreettista kontribuutiota syntyi myös siitä, että aineettoman varallisuuden kehittämistä organisaatioissa on pidetty ongelmallisena nimenomaan mittareiden ja mittausmenetelmien puuttumisen vuoksi. Malli sisältää monia tätä tarkoitusta palvelevia mittareita ja mittausmenetelmän. Merkittävää teoreettisen kontribuution osalta oli myös se, että organisaatiot hankkiessaan palveluita voivat samalla kehittää omaa innovaatiokykyään yhdistämällä hankintoihinsa haasteellisia innovaatioasetelmia. Laaja hankintatoimeen liittyvä aineisto auttaa muutenkin ymmärtämään keinon ja lopputuloksen suhteita. Tutkimuksen tuloksia pystyttiin reflektoimaan myös olemassa olevaan teoriaan usean kiinnekohdan kautta. Yhtenä reflektointikohtana oli se, että mallin avulla organisaatiot pystyvät vähentämään organisaatio- ja talousteorioissa havaittuja epävarmuuksia, jotka liittyvät kumppaneiden valintaan ja organisaation hankintatoimeen

MRI radiographers had received magnetic resonance imaging training in radiographers‘ educations (65.8%). Most of the MRI training happening at the workplace was given by the colleagues. Also self-knowledge acquisition was used. The result reveals that there is need for continuing educations on all areas of MRI. The training is required for magnetic resonance image quality and optimization. The most important forms of continuing education are MRI equipment suppliers and employers educations. Also the training given by colleagues is valued. MRIs continuing training should be given once a year. In Finland we are not able to utilize the online-learning of MRIs continuing training yet. In the future training needed in health care will increase. This is also the case in magnetic resonance imaging. According to the results the continuing educations can be organized for in MRI radiographers when needed. Evidence-based radiography could be one way to meet the need for educations in the area of magnetic resonance imaging

Texto completo da fonteThe goal of this master’s thesis is to develop type design of a pedestrian bridge with steel superstructure and timber deck. The purpose is to find a cost-effective structural solution for the bridge so that the required comfort level can be reached. In particular, the goal is to analyze how the length and width of the bridge influences the requirements for material strength in the superstructure and to find out when it is necessary to assess the pedestrian comfort more carefully. Analysis and dimensioning of the timber deck is carried out by classical beam theory and the orthotropic plate theory. Classical beam theory is used in dimensioning of the primary beams and vibration analysis of the bridge is performed by manual calculations. If spacing between the main beams remains the same, the width of the bridge does not have a significant effect on the design of the deck and steel structures in the ultimate limit state. The alternative analyzes gives different results. Classical beam theory gives bigger values for forces and moments in design of the timber deck. The controlling traffic load is the service vehicle. The critical design verification for the primary steel beams is lateral torsional buckling. According to calculations, the natural frequency of the longest bridge is so low that it is necessary to use more accurate analyzes for vibration sensitivity

Texto completo da fonteTiivistelmä Väitöskirjani tehtävänä on selvittää pienten koulujen esiopetuksen järjestämistä. Esiopetusta on järjestetty Suomessakin jo yli kolmekymmentä vuotta, mutta laaja esiopetuksen järjestämisen aika kuusivuotiaille on vasta aluillaan vuoden 2001 alusta. Teoreettisessa osassa 1 tarkastelen pienten koulujen historiallista kehittymistä, koulutuspolitiikkaa, pedagogiaa ja esiopetuksen järjestämistä osana koko koululaitosta. Vertailen Suomen naisten työssäkäyntiä, päivähoidon järjestämistä ja naisten tasa-arvoa muuhun Eurooppaan, samoin lasten koulumenestystuloksia. Esiopetuksen järjestämisen laatua tarkastelen Helakorven (1993) esittämästä opetuksen laatuelementtimallista kootun mallin avulla. Empiirisessä osassa 2 analysoin hallinnon edustajien, vanhempien, opettajien ja lasten käsityksiä esiopetuksesta. Toteutin tutkimuksen kyselylomakkeilla neljässä vaiheessa vuosina 1999-2000 ja sain yhteensä 2271 palautuskirjettä. Faktorianalyysien tehtävänä oli jäsentää ilmiötä ja antaa tukea teoreettisen tiedon ja oman praktisen työkokemuksen pohjalta laaditulle tulkinnalle. Esiopetuksen järjestämisessä on samankaltaisuutta 1800-luvulla maaseudun lapsille järjestetyn alkuopetuksen kanssa: maaseudun lapset ovat olleet opetuksen saamisessa huonommassa asemassa kuin taajamien lapset. Syrjäseudun esioppilaille tulisi antaa kuljetusetu erityispalveluna erityisesti vanhempien mielestä. Suomen pitäisi tiedostaa selkeästi oman identiteettinsä perustekijät eli suuri maa ja pieni väestö. Siksi yhdysluokkaopetusta ja eri-ikäisten lasten oppimista yhdessä pitäisi yleensäkin tutkia ja kehittää enemmän. Esiopetukseen suhtautumisessa eri ryhmien vastaukset eroavat vain vähän toisistaan. Hallinnon edustajat, vanhemmat ja opettajat korostavat käytöstapojen ja tapakasvatuksen tärkeyttä. Lapset korostavat ulkoleikkiä ja yleensä leikkiä sekä ilmapiirin merkitystä samoin kuin vanhemmat. Kansainvälisyyden ja tieto- ja viestintätekniikan opetusta ei nähdä tärkeiksi alueiksi esiopetuksessa. Koulutuksen tehtävä on ihmisyyteen kasvattaminen. Esiopetusikää pitäisi vaalia omana ikäkautenaan. Suomessa onkin satsattu opettajien koulutukseen ja päivähoidon kehittämiseen, ei lapsen varhaiseen koulunaloitukseen. Oppilaiden myöhemmät koulumenestystulokset tukevat Suomen linjan säilyttämistä, eivät muiden Euroopan maiden matkimista. Hallinnollisesti esiopetuksen johtamisen keskeinen haaste on päiväkodin johtajien sekä koulutoimen ja perusturvan esiopettajien asiantuntemuksen laajempi hyödyntäminen sekä paikallisuuden huomioon ottaminen. Opettajat tarvitsevat täydennyskoulutusta erityisesti erityispedagogiikassa, vuorovaikutustaitojen harjoittamisessa ja vanhempien kanssa tehtävässä yhteistyössä. Yhteistyöhön tulisikin saada resursseja ja aikaa hallinnolta. Jatkotutkimusvaiheessa voisi puolestaan toimintatutkimuksen avulla kehittää kodin ja koulun yhteistyötä. Arviointimallin käyttö tapauskohtaisissa kuntatutkimuksissa, eri ryhmien edustajien haastattelut ja seurantatutkimus esiopetuksen järjestämisen vakiintumisen jälkeen tarjoavat mielenkiintoisia jatkotutkimusmahdollisuuksia

Texto completo da fonteTiivistelmä Tutkimuksen konteksti on perusopetukseen valmistavan opetuksen projekti, jota opettajat toteuttivat kolmivaiheisen TriPod-mallin mukaisesti. Opetuksen kolme vaihetta olivat luokassa toteutettava orientaatio, opintovierailu koulun ulkopuolelle ja siinä saatujen kokemusten reflektointi koulussa. TriPod-mallin mukainen opetus perustui ensisijaisesti kokemuksellisen ja yhteisöllisen oppimisen periaatteille ja siinä hyödynnettiin systemaattisesti koulun ulkopuolisia autenttisia oppimisympäristöjä 8–9 kertaa lukuvuodessa kolmen ja puolen vuoden aikana. Tutkimukseni tavoitteena oli tutkia valmistavan opetuksen opettajien (valo-opettajien) osaamisen kehittymistä projektin aikana. Toisessa tutkimusongelmassa tutkittiin TriPod-mallin mukaisen opetuksen soveltuvuutta maahanmuuttajataustaisten valo-oppilaiden opetuksessa ja kotoutumisen edistämisessä. Tutkimukseni tietoteoreettisena lähtökohtana on sosiaalinen konstruktivismi. Tutkimus toteutettiin laadullisena tutkimuksena, jonka metodologinen viitekehys sisälsi piirteitä toimintatutkimuksesta sekä etnografisesta ja fenomenografisesta tutkimustraditiosta. Tutkimuksen aineisto hankittiin pääosin yhdeksältä valo-opettajalta teemahaastattelun avulla ja analysoitiin abduktiivisen laadullisen sisällönanalyysin avulla. Tutkimuksen perusteella voidaan todeta, että valo-opettajille muodostui oma ”oppimisympäristö”, jossa osaaminen kehittyi sekä subjektiivisen että yhteisöllisen reflektoinnin kautta. Projektin aikana kehitettiin valmistavan opetuksen didaktiikkaa, johon liittyi kiinteästi koulun ulkopuolisten oppimisympäristöjen hyödyntäminen. Valo-opettajat kokivat opetussuunnitelman tukevan projektissa toteutettuja periaatteita ja käytäntöjä, mikä puolestaan vahvisti käytännön ja teorian integroitumista. Tutkimuksessa nousi esille tarve sopeuttaa valo-opettajien ja erityisesti vierailukohteiden asiantuntijoiden opetuspuhetta vastaamaan valo-oppilaiden suomen kielen taitotasoa. Valo-opettajat tiedostivat työnsä yhteiskunnallisen merkityksen kotoutumista edistävien opetuskäytänteiden toteuttajina. Tutkimuksen tuloksena kehitettiin uusi sovellus opettajan käytännön teoriasta; se tarjoaa yhden perustellun näkökulman yhteiskunnallisten muutosten edellyttämiin opetuksellisiin haasteisiin, jotka tulisi ottaa huomioon opettajankoulutuksessa ja opettajien täydennyskoulutuksessa
