The central theme for this study is graduate employment and employability in European-wide discussion. In this study, the complex relationships between higher education and the world of work are explored from the vantage point of how individuals make use of the higher education system in their transition from education to employment. The variation among individual transition processes in nine European countries is analysed with the help of a comparable graduate survey. Countries in this study are Italy, Spain, France, Austria, Germany, the Netherlands, the United Kingdom, Finland, and Norway. The data used for the study is commonly known as the “CHEERS” or “Careers after Higher Education, A European Research Survey.” The data was collected in 1999. The study discusses the possibilities and limitations the higher education system has in supporting the initial education-to-work transitions of youth. The study also addresses problems with comparing national higher education systems in terms of enrolment and graduate employability. A central purpose for this study is to reflect on concerns about the prolongation of individual transitions with a framework that simultaneously considers both the graduate employability and the duration of the education-to-work transition process. The key concept for this study is the standard student/graduate; synonym concepts are the traditional and the conventional student/graduate. Standard graduates are relatively young individuals who are performing their initial transition from education to working-life and who complete the degree-earning process within the stipulated time frame. In all nine countries, standard graduates make up a considerable share of the student flow, passing from higher education to the labour markets. The share of standard graduates is by far the largest in France, where they comprise the overwhelming mass. The proportion of the standard graduates is the lowest in Italy, Finland, and Austria where approximately one in four graduates completed the process of higher education within the stipulated time frame. Of the nine countries compared, employability of the whole graduate population is the greatest in Norway, the UK, Finland, and the Netherlands. Compared with employability of the whole graduate population, variation among the countries is considerably reduced when reviewing the employability of only the standard graduates. Thereby, even though the ranking among countries remains largely unchanged, the variations among them are smaller when the duration of degree earning process is standardized. The study also discusses other ideal types of student careers (or transition processes) besides the standard student/graduate. Results of regression analyses indicate that that at the pan-European level analysis, the graduate labour markets are not heavily segmented in terms of the type of the individual transition process. When considering within-country differences between the graduates, the field of studies is clearly a more powerful explanatory variable than the type of the transition process. There are, nevertheless, clear indications that, irrespective of the country, chances of finding a high status job are, on the average, highest amongst those who graduate within the stipulated duration of the degree program and who thereby have experienced the standard student career, whereas, participating in working life while studying protects against unemployment after finishing one’s degree.

Expatriation has become increasingly common due to the global trade expansion. Many large companies base their production facilities in far-flung countries, where experts are sent from their own countries to launch the operations. Working in a foreign environment demands from so-called expatriates considerable adaptability. This study aimed to investigate if following expatriation mental health difficulties were experienced by the employees themselves or their family members. This study investigated by a questionnaire and interviews how expatriate employees in Finnish companies operating in different regions of Brazil and their families adjusted. Investigated employees were required to be at least 6 months in expatriation. Data were collected in Brazil during their stay at least 3 months after the arrival. The survey covered 121 expatriate employees, that operated in 17 different companies, from which 71 employees from 10 different companies responded to the questionnaire. All the employees from the two largest enterprises and their spouses were invited to focus groups; in total 43 persons (22 employees and 21 employees’ spouses) participated in a group or individual interviews. No significant mental health difficulties were found among the expatriate employees. Only a tenth of the expatriate employees reported strain. The experience of strain symptoms was found to be related to long working days, intense working rhythm and lack of friends. Work satisfaction seemed to be an important mediator in the coping process. While abroad, the expatriate employees were highly recognized for their work. Due to the immature organization of work they could often use their creative capacities to improve the work flow. The opportunity to see the effects of their own contribution with their own eyes to the development of the enterprise made them feel good. The association between the expatriate employees’ adjustment and that of their spouses’ was evident. The spouses’ situation was markedly different than that of the expatriate employees’ themselves. Expatriation changed the family members’ previous division of tasks considerably. The expatriate spouses had to change their roles more than the expatriate employees themselves; since most of them were highly educated women, who were leaded through an identity crisis due to at least temporary renunciation of own work and career.

The correct utilization of non-wood raw material allows reducing tree cutting and reduces emissions of carbon dioxide from burning of non-wood plants on farmers fields. Also it allows increasing economical situation in regions that non-wood plants are grown and where they are converted into pulp and paper. Also it gives positive effect on population pressure of work by addition of working place. In the literature survey included an overview of the historical meaning of non-wood pulp on developing paper production and structure of non-wood pulps. Moreover, anatomical and chemical composition of straw, reed and bamboo were studied more detailed. Also, an overview of the utilization of non-wood pulp in papermaking was made. Especially tissue, tree-free and release papers were reviewed. In the experimental part the goal was to investigate suitability of non-wood pulp like wheat straw pulp and bamboo pulp for different fiber products. Finally release and tree-free paper products were selected for experimental studies. It was discovered that wheat straw, especially screened wheat straw, showed good results for release paper. Also utilization of wheat straw and bamboo pulp in tree-free paper showed good results and suitability of these non-wood pulps for tree-free paper production. Also it was noticed that addition of wheat straw pulp gave positive effect on initial wet strength for release and tree-free paper.

Case-based reasoning (CBR) is a recent approach to problem solving and learning that has got a lot of attention over the last years. In this work, the CBR methodology is used to reduce the time and amount of resources spent on carry out experiments to determine the viscosity of the new slurry. The aim of this work is: to develop a CBR system to support the decision making process about the type of slurries behavior, to collect a sufficient volume of qualitative data for case base, and to calculate the viscosity of the Newtonian slurries. Firstly in this paper, the literature review about the types of fluid flow, Newtonian and non-Newtonian slurries is presented. Some physical properties of the suspensions are also considered. The second part of the literature review provides an overview of the case-based reasoning field. Different models and stages of CBR cycles, benefits and disadvantages of this methodology are considered subsequently. Brief review of the CBS tools is also given in this work. Finally, some results of work and opportunities for system modernization are presented. To develop a decision support system for slurry viscosity determination, software application MS Office Excel was used. Designed system consists of three parts: workspace, the case base, and section for calculating the viscosity of Newtonian slurries. First and second sections are supposed to work with Newtonian and Bingham fluids. In the last section, apparent viscosity can be calculated for Newtonian slurries.

In Finland, vocationally oriented medical rehabilitation (ASLAK®) is a common preventive rehabilitation measure with the primary goal of preserving and improving work ability. The ASLAK® programme has been used for almost 30 years, although limited data exist on its effectiveness. The aims of this study were to determine whether the increased risk of work disability predicts the participants’ likelihood to be granted ASLAK® rehabilitation and to assess the effectiveness of the programme in decreasing the risk of work disability and modifying health-risk behaviours. This study is a part of the on-going Finnish Public Sector Study conducted by the Finnish Institute of Occupational Health. Data on 53 416 employees (81% women) were gathered from employers’ records, national health registers and repeated survey responses. During the 5-year follow-up, increased levels of the risk factors for work disability did not predict participation in the rehabilitation programme. During the 2.8-year followup (range 0.04–5.0 years), the risk of long-term work disability (sick leave >90 days or retirement) overall or, more specifically, due to musculoskeletal or mental diseases did not differ between the rehabilitants who participated in ASLAK® in 1997–2005 and their propensity score matched controls. There was no evidence of ASLAK® being effective in changing participants’ health-risk behaviours or in improving perceived general or mental health. The results suggest that potential participant recognition, mainly taking place in occupational health care, may fail to identify those with a higher risk of work disability. No evidence on the effectiveness of the programme was found in the study cohort when measured by the selected indicators.

Human trafficking is not a new phenomenon. It has existed in various forms for ages around the world. Some researchers have even compared it to slavery, calling it the modern form of slavery in the 21st century. This study is particularly interested in the role of work-related human trafficking in Finnish business. In order for something to be called work-related human trafficking, the concepts of forced labour and human trafficking have to overlap. From the economic point of view, human trafficking is governed by the laws of supply and demand. In many countries the global pressure on cutting costs has created two trends: the increased supply of migrant workers and the deregulation of labour markets. These competitive pressures can have an adverse impact on the conditions of employment and, in the worst cases, can lead to forced labour and trafficking. In fact, trafficking has become one of the most profitable illicit industries worldwide, generating tremendous profits due to its low costs and huge profits. Therefore, it is important to investigate the phenomenon from the business point of view. This study is a qualitative research conducted by using theme interviews as a research approach. Altogether 13 interviews have been conducted and some secondary data has been used in order to find out what the role of human trafficking is in Finnish business. The special sectors investigated are the Finnish construction and service sectors. The theory framework used in this study follows the stakeholder approach. The relevant stakeholder groups for this study are: ‘institutions and authorities’, ‘law enforcement’, ‘management’ and ‘employees – potential victims’ of trafficking. With the help of these stakeholder groups, a holistic picture of the phenomenon is formed. It can be concluded that the role of human trafficking is complicated but it does exist in Finnish business. It appears in low-cost business sectors where the demand for cheap labour is high. Thus, often the victims are foreigners who do not know the culture or the Finnish conditions of employment. Especially smaller Finnish companies are at risk of getting involved in human trafficking or related exploitation cases since monitoring is much more scarce in these firms than in larger companies. The risk of human trafficking and exploitation is also higher at the bottom of the complicated subcontracting chains or when using foreign recruitment agencies. Thus, the study believes that active and intensive collaboration between the company’s different stakeholder groups is needed in order to prevent work-related human trafficking from flourishing in Finland.

There are vast changes in the work environment, and the traditional rules and management methods might not be suitable for today’s employees anymore. The meaning of work is also changing due to the younger and higher educated generations entering the markets. Old customs need to be re-validated and new approaches should be taken into use. This paper strongly emphasizes the importance of happiness research and happiness at work. The values towards the meaning of work are changing; people demand happiness and quality from all aspects of their lives. The aim of this study is to define happiness - especially at work - and to explain how it can be measured and what kind of results achieved. I also want to find out how the contents of work and the working environment might enhance happiness. The correlation between education and happiness is discussed and examined. I am aware that the findings and theories are concentrating mainly on Western Countries and highlighting the values and work-environments of those societies. The main aim of the empirical study is to find out if there are connections between happiness and work in data collected by World Value Survey in 2005, and if the profession has effects on happiness. Other factors such as the correlation of age, sex, education and income are examined too. I also want to find out what kind of values people have towards work and how these affect the happiness levels. The focus is on two nations: Finland (N=1014) and Italy (N=1012). I have also taken the global comparison within, that is all 54 countries (N=66,566) included in the 5th wave (during the years 2005 -2008) of the World Value Survey. The results suggest that people are generally happy around the world; happiness decreasing with the age, the educated being happier than the uneducated and the employed happier than the unemployed. People working in neat “white collar” jobs are more likely happier than those working in factories or outdoors. Money makes us happier, until certain level is reached. Work is important to people and the importance of work adds happiness. Work is also highly appreciated, but there are more happy people among those who do not appreciate work that highly. Safety matters the most when looking for a job, and there are more happy people among those who have selected the importance of work as the first choice when looking for a job, than among those to whom an income is the most important aspect. People are more likely happy when the quality of work is high, that is when their job consists of creative and cognitive tasks and when they have a feeling of independence.

1990-luvun alussa lainsäädäntö ja työmarkkinajärjestöt määrittelivät Suomessa, että vuokratyötä tuli käyttää vain tilapäiseen työvoimatarpeeseen, esimerkiksi sijaisuuksiin ja ruuhkahuippuihin. Joillakin aloilla vuokratyö oli työnantajien ja työntekijöiden yhteissopimuksella kielletty. Vaikka vuokratyösuhteet saivat jo 1980-luvulla niin Suomessa kuin kansainvälisestikin maineen työsuhdekeinotteluna, alkoi vuokratyön määrä Suomessa kasvaa 1990-luvun puolivälissä ja erityisesti tultaessa 2000-luvulle. Suomalaiset akateemiset tutkijat eivät ole juuri vuokratyöstä kiinnostuneet. Aiemmat, harvalukuiset tutkimukset ovat keskittyneet lähinnä työyhteisöjen ja työntekijöiden kokemuksiin sekä vuokratyön työehtoihin. Vuokratyö ymmärretäänkin edelleen lähinnä työntekijän subjektiivisena kokemuksena. Vuokratyössä on kuitenkin kysymys paitsi kokemuksista, myös yhteiskunnallisesta valtakamppailusta, jossa diskursiivisin keinoin pyritään vaikuttamaan ilmiöön nimeltä vuokratyö, laajemmin ilmiöön nimeltä työmarkkinat, sekä toisaalta kansalaisten käsityksiin työelämän ”normaalista”. Käsillä oleva tutkimus laajentaa ymmärrystä vuokratyöstä tarkastelemalla ilmiötä lainsäädännön, uutisoinnin ja markkinoinnin rakentamien julkisten käsitysten ja merkityksenantojen kautta. Teoreettisena viitekehyksenä käytän hallinnan ja työprosessin säätelyn teoriaperinteitä. Se, miten työmarkkinoiden muutosta ja uusia työsuhdemuotoja politiikassa, mediassa, lainsäädännössä, tai työpaikan kahvipöytäkeskusteluissa perustellaan ja tehdään ymmärrettäväksi, on samalla työelämään kiinnitettävien arvojen, merkitysten ja toimijuuksien luomista, rajaamista ja kuvailua. Työelämäpuheessa ei siis ole kyse vain talouden lainalaisuuksista, kansantalouden toimivuudesta, tai yritysten kilpailukyvystä, vaan myös ja erityisesti niiden toimijoiden luomisesta, määrittelemisestä ja legitimoimisesta, jotka työelämän kentällä saavat toimia ja tulevat palkituiksi. Säätelyn ja hallinnan näkökulmasta on relevanttia tarkastella millaisilla käsitteillä ja merkityksillä vuokratyötä ilmiönä rakennetaan . Tutkimuskysymyksinä esitän: 1) Miten ja millä perusteilla vuokratyöstä rakennettiin Suomessa legitiimi tapa työllistää ja työllistyä? 2) Millaisia työntekijäideaaleja vuokratyöhön liittyvissä keskusteluissa rakennetaan? Tutkimusaineistona tarkastelen lainsäädäntöön liittyviä dokumentteja, Helsingin Sanomien uutisointia, vuokratyöyritysten markkinointimateriaaleja, sekä vuokratyöyritysten edustajien haastatteluita. Analyysimenetelmänä käytän kriittistä diskurssianalyysia. Tämä menetelmä mahdollistaa puheen ja dokumenttien tarkastelun sosiaalisena toimintana, jolla eri toimijat pyrkivät osallistumaan yhteiskunnassa hyväksyttyjen ja tunnustettujen käsitysten ja toimintavaihtoehtojen rakentamis-, tulkinta- ja määrittelyprosesseihin. Tutkimukseni päätuloksena esitän, että vuokratyöstä muodostui legitiimi tapa työllistää Suomessa 1990-luvulla, koska vuokratyö käsitteellistettiin sekä lainsäädännön että median diskursseissa ennen kaikkea ratkaisuksi työttömyyteen. Toisaalta vuokratyö käsitteellistettiin vain marginaalisten työntekijäryhmien (naiset ja opiskelijat) rooliksi, jolloin se ei liittynyt miesvaltaisten työpaikkojen arkeen. Ratkaisuna työttömyyteen vuokratyö myös samalla luonnollistettiin osaksi yleisempää työmarkkinakehitystä, jolle ”kukaan ei voi mitään”. 2000-luvulla vuokratyö jatkoi voittokulkuaan ja rakentui pysyväksi ilmiöksi, koska työlainsäädännön uudistus institutionalisoi vuokratyön työehtosopimusmenettelyyn, jolloin sen ”salonkikelpoisuus” ja normaalius vahvistettiin. Vaikka työehtosopimusasia oli ratkaisuna merkittävä, nousi vuokratyön osalta itse työehtosopimus tärkeämmäksi kuin sen sisältö. Työehtosopimuksilla ei kuitenkaan pystytty vaikuttamaan esimerkiksi vuokratyöntekijän olemattomaan työsuhdeturvaan. Lisäksi työnantajapuhe käsitteellistää vuokratyön 2000-luvulla ennen kaikkea työmarkkinavaihtoehdoksi, vapautta ja monipuolisia työkokemuksia tarjoavaksi työmarkkinoiden katalysaattoriksi. Vuokratyö on tässä merkitysavaruudessa työntekijöille ”vain” yksi tapa työllistyä ja löytää oma tiensä työmarkkinoille, ei suinkaan työnantajien sanelema pakko. Työntekijöihin kohdistuva hallintapuhe niin mediassa kuin työnantajien haastatteluissakin pyrkii puolestaan rakentamaan ideaalityöntekijäkuvaksi yrittäjämäisen oman elämänsä toimitusjohtajan. Työnantajien diskursseissa kaikuvatkin työntekijään kohdistuva vaatimus itse itsensä ohjaamisesta sekä työntekijäidentiteetin muotoilemisesta joustavuutta, sopeutuvuutta, vaihtelua ja jatkuvaa muutosta vähintäänkin sietäväksi, mutta mieluiten näitä ominaisuuksia jopa aktiivisesti hakevaksi ja arvostavaksi. Työmarkkinoiden toimijana on nimenomaisesti yksilö, jonka mahdollisuudet menestyä ovat vain ja ainoastaan hänen omissa käsissään. Työntekijän roolin korostaminen aktiivisena toimijana ja vuokratyöstä ”oikeita”, norminmukaisia sisältöjä löytävänä pärjääjänä on diskursiivisesti hallittua yritystä ohjata työntekijöitä näkemään sekä itsensä tietynlaisina toimijoina että työmarkkinat tietyllä tavalla toimivina. Vuokratyössä ei ole kyse vain työntekijöiden yksilöllisistä tai yksittäisistä kokemuksista. Vuokratyö on yhteiskunnallisen merkityskamppailun tulos, jossa käyttövoimana ovat toimineet hallinnalliset ja säätelyyn pyrkivät käsitteellistykset työllisyydestä, yksilön valinnasta ja koko yhteiskunnan edusta. Hallinnan ja säätelyn näkökulmasta katsottuna vuokratyö on myös merkinnyt säätelyn liukumista tasa-arvoa, yhdenmukaista kohtelua ja työntekijän suojelua korostavasta viranomaisten ja poliittisten toimijoiden suorittamasta työmarkkinoiden kollektiivisesta säätelystä työnantajien ylläpitämään työntekijän persoonan ja käyttäytymisen hegemoniseen, yksilölliseen säätelyyn.

Avhandlingen har sitt utspring i mitt engasjement for elevers møte med kunst i grunnskolen i faget kunst og håndverk og mitt syn på ungdom som kompetente bidragsytere til forskningen om fenomener som angår deres liv. Elevene er informanter til, eller aktører i, forskning på fenomenet dialog med kunst. Dialog med kunst er her definert som en helhetlig prosess som innlemmer alt fra elevenes møte med visuelle kunstverk til deres eget skapende arbeid. At avhandlingens fagdidaktiske problemområde er elevers praktisk skapende virksomhet, knytter undersøkelsen til slöjdpedagogisk forskning. Avhandlingens overgripende hensikt er å bidra til utvikling av fagdidaktikken i kunst og håndverk med utgangspunkt i elevenes erfaringer med kunstundervisningens innhold og metode på ungdomsskoletrinnet. Studien består av kasusstudier på to ungdomsskoler. Data ble innsamlet igjennom intervjuer, deltakende observasjon, dokumenter, prosessbøker og foto av formingsprodukter. Ungdoms dialog med kunst i skolen blir analysert og fremstilt ut fra et erfart og et operasjonalisert perspektiv. Funnene speiles i ulike fagdidaktiske tendenser, det vil si ulike hovedoppfatninger i debatten om det moderne samfunn, og i et virksomhetsteoretisk perspektiv. Resultatene fra undersøkelsen utfordrer oss til en fagdidaktisk nyorientering når det gjelder ungdoms møte med kunstverk i skolen, i retning av et mer ungdomskulturelt innhold og relasjonelle kunstmøter som er narrative, tolkningsorientert, opplevelsesorientert, dialogiske og flerstemmige. Undersøkelsen viser at elevene liker det praktisk skapende arbeidet, men at undervisningen i sterkere grad bør ta i bruk digital kunnskap og handle om hvordan kunst kan brukes som utgangspunkt for skapende arbeid, og den bør legge til rette for det læringspotensialet som ligger i dialogen elevene imellom. Elevene liker en undervisning som ikke bare handler om estetiske virkemidler, materialer og teknikker, men også om kommunikasjon og ytringsfrihet. Resultatene viser at det frie skapende arbeid består av tre likeverdige aspekter: det individuelle, det kulturelle og det sosiale. Både funnene og avhandlingens virksomhetsteoretiske perspektiv kan bidra til diskursen om kreativitetsbegrepet og identitetskonstruksjon i vårt moderne samfunn. Virksomhetssystemet blir i denne avhandlingen utviklet til en teori for skapende arbeid i faget kunst og håndverk, et overgripende fagdidaktisk rammeverk for bild/bildkonst og slöjdfaget satt inn i et nordisk utdanningsperspektiv.

The purpose of this research was to provide a deeper insight into the consequences of electronic human resource management (e-HRM) for line managers. The consequences are viewed as used information system (IS) potentials pertaining to the moderate voluntaristic category of consequences. Due to the need to contextualize the research and draw on line managers’ personal experiences, a qualitative approach in a case study setting was selected. The empirical part of the research is loosely based on literature on HRM and e-HRM and it was conducted in an industrial private sector company. In this thesis, method triangulation was utilized, as nine semi-structured interviews, conducted in a European setting, created the main method for data collection and analysis. Other complementary data such as HRM documentation and statistics of e-HRM system usage were utilized as background information to help to put the results into context. E-HRM has partly been taken into use in the case study company. Line managers tend to use e-HRM when a particular task requires it, but they are not familiar with all the features and possibilities which e-HRM has to offer. The advantages of e-HRM are in line with the company’s goals. The advantages are e.g. an transparency of data, process consistency, and having an efficient and easy-to-use tool at one’s disposal. However, several unintended, even contradictory, and mainly negative outcomes can also be identified, such as over-complicated processes, in-security in use of the tool, and the lack of co-operation with HR professionals. The use of e-HRM and managers’ perceptions regarding e-HRM affect the way in which managers perceive the consequences of e-HRM on their work. Overall, the consequences of e-HRM are divergent, even contradictory. The managers who considered e-HRM mostly beneficial to their work found that e-HRM affects their work by providing information and increasing efficiency. Those managers who mostly perceived challenges in e-HRM did not think that e-HRM had affected their role or their work. Even though the perceptions regarding e-HRM and its consequences might reflect the strategies, the distribution of work, and the ways of working in all HRM in general and can’t be generalized as such, this research contributed to the field of e-HRM and it provides new perspectives to e-HRM in the case study organization and in the academic field in general.

This study is based on the notion that all students are likely to have a computer of some kind as their primary tool at school within a few years. The overall aim is to contribute to the knowledge of what this development of computer-assisted multimodal text production and communication on and over the net may entail in a school context. The study has an abductive approach drawing on theory from Media and Communication studies and from Pedagogy - particularly on media peda-gogy, multimodality, storytelling, conversation research and deliberative democracy – and is based on a DBR project in three schools. The empirical data are retrieved from four school classes, school years 4 and 5, with good access to computers and digital cameras. The classes have used the class blogs to tell the blog visitors about their school work and Skype to communicate with other classes in Sweden and Tanzania. A variety of research methods was employed: content analysis of texts, observations with field notes and camera documentation, interviews with individual students, group interviews with teachers and students, and a small survey. The study is essentially qualitative, focusing on students’ different perceptions. A small quantitative study was conducted to determine if any factors and variables could be linked to each other and to enable comparisons of the surveyed group with other research results. The results suggest that more computers at school offer more opportunities for real-life assignments and the chance to secure an authentic audience to the students’ production; primarily the students’ parents and relatives, students in the same class and at other schools. A theoretical analysis model to determine the degree of reality and authenticity in various school assignments was developed. The results also indicate that having access to cameras for documenting various events in the classes and to an authentic audience can create new opportunities for storytelling that have not been practiced previously at school. The documentary photo invites a viewer into the present tense of the image and the location where the picture was taken, whoever took the picture. It is used by the students and here too, a model has been developed to describe this relationship. The study also focuses on the freedom of expression and democracy. One of the more unexpected findings is that the students in the study did not see that they can influence other people’s perceptions or change various power structures through communication on the web, neither in nor outside of school.

The aim of this work is to study the results of tensile tests for austenitic stainless steel type 304 and make accurate FE-models according to the results of the tests. Tensile tests were made at Central Research Institute of Structural Material, Prometey at Saint Petersburg and Mariyenburg in Russia. The test specimens for the tensile tests were produced at Lappeenranta University of Technology in a Laboratory of Steel Structures. In total 4 different tests were made, two with base material specimens and two with transverse butt weld specimens. Each kind of a specimen was tested at room temperature and at low temperature. By comparing the results of room and low temperature tests of similar test specimen we get to study the results of work hardening that affect the austenitic steels at below room temperature. The produced specimens are to be modeled accurately and then imported for nonlinear FEM- analyzing. Using the data gained from the tensile tests the aim is to get the models work like the specimens did during the tests. By using the analyzed results of the FE-models the aim is to calculate and get the stress-strain curves that correspond to the results acquired from the tensile tests.

Today lean-philosophy has gathered a lot of popularity and interest in many industries. This customer-oriented philosophy helps to understand customer’s value creation which can be used to improve efficiency. A comprehensive study of lean and lean-methods in service industry were created in this research. In theoretical part lean-philosophy is studied in different levels which will help to understand its diversity. To support lean, this research also presents basic concepts of process management. Lastly theoretical part presents a development model to support process development in systematical way. The empirical part of the study was performed by performing experimental measurements during the service center’s product return process and by analyzing this data. Measurements were used to map out factors that have a negative influence on the process flow. Several development propositions were discussed to remove these factors. Problems mainly occur due to challenges in controlling customers and due to the lack of responsibility and continuous improvement on operational level. Development propositions concern such factors as change in service center’s physical environment, standardization of work tasks and training. These factors will remove waste in the product return process and support the idea of continuous improvement.
