Leimuhitsauksen laadunhallinnassa tärkeää on prosessimainen toiminta ja toimintojen kokonaisvaltaisuuden hahmottaminen. Leimuhitsauksen ollessa osana päättymätöntä valssausta hitsauksen laadunhallinta voidaan jakaa kolmeen päävaiheeseen: ennen hitsausta, hitsauksen aikana ja hitsauksen jälkeen vaikuttaviin laaduntuottotekijöihin. Leimuhitsauksen laaduntuottotekijöiden määritys ja jaottelu kaavioiksi on toteutettu tässä työssä. Leimuhitsin tekniseen laatuun vaikuttavat monet ilmiöt ja parametrit hitsauksen aikana. Tärkeimpiä hitsausparametreista ovat hitsausjännite, alustan liikenopeus, tyssäysmatka sekä leimutusaika. Väärät hitsausolosuhteet tai hitsausparametrit aiheuttavat erilaisia mekaanisia ja metallurgisia vikoja leimuhitsiin. Eräs metallurginen vikatyyppi ovat oksidisulkeumat hitsialueella. Nämä hapettuneet alueet voivat johtaa juurensa erilaisista syistä ja esimerkiksi leimutusajan ja epätasaisen liitospinnan yhteyttä sulkeumien syntyyn on epäilty. Pidennetyillä leimutusajoilla tehtyjen hitsauskokeiden ja hitsien rikkovien aineenkoetuskokeiden tuloksena todettiin tässä tutkittujen koehitsien oksidisulkeumien syntyvän hapettumalla leimutuksen aikana tai juuri hetkellä ennen tyssäystä, minkä lisäksi kosteat olosuhteet hitsausatmosfäärin ympärillä heikentävät lopputuloksen laatua. Leimutusajalla on tärkein osa leimutettavia pintoja tasaavana tekijänä ja mitä epätasaisempi liitettävä pinta on, sitä pidemmän leimutusajan se tarvitsee.

From the world of fiction literature into multi-cultural Finland. Anticipatory story as an educational tool in teaching of literature and multiculturalism The research clarifies the relationship between reading fiction literature and multicultural value education in basic education. The research focuses on the subject didactics of mother tongue and literature and on the literature teaching in particular. The objective is to develop a method that is easily transferable into a teaching context so as to intensify the educational discussion based on fiction literature. In essence, understanding fiction literature and the ethical and moral thinking resemble one another, because both of them aim at empathizing with the thinking of a person or with a situation foreign to oneself. For this reason fiction literature is ideally suited for the discussion on ethical and moral values within a subject entity in the basic education. The empirical unit of the research consists of two parts. The first part explains how youth novels published in the years 1993 – 2007 describe multiculturalism in Finnish society. Books on multiculturalism are still few in number within youth literature, and people with a foreign background are mainly minor or background characters in such literary works. Nevertheless, youth novels serve well as a starting point for an educational discussion about multicultural issues. More often than not characters in youth novels are stereotypes and even opposite to each other. The juxtaposing makes a young reader question the stereotypes associated with immigrants. Besides the stereotype, reference to a prototype or a model is possible. The second part tests the usefulness of an anticipatory story based on a fictive text for an educational discussion about multicultural issues. The empirical material was collected from the eighth-grade teaching groups in basic education as follows: one teaching group was an immigrant group, the second one a group of Finns with experience of immigrants while the third group of students had hardly any experience of immigrants. The anticipatory stories were written on the basis of extracts from youth novels with multicultural themes. The material collected for a total of 120 anticipatory stories was analysed by using meaning cue analysis. Using the meaning cue analysis, the anticipatory stories were divided into three groups: stories with predominantly positive meaning cues of interculturalism, ambivalent stories with both positive and negative meaning cues of interculturalism and the stories with predominantly negative meaning cues of interculturalism. The meaning cues produced by girls and boys differ from one another, in particular, by the negative meaning cues of interculturalism. For girls, the predominant meaning cue is fear whereas for boys, it is that of violence. It would also seem that the students, in particular, boys with little experience of immigrants produce more negative meaning cues of interculturalism than do immigrants or Finnish students with experience of immigrants. Further still, it seems that active reading of fiction literature affects the meaning cues of interculturalism in an ambivalent direction. In the way of youth novels this is understandable, because youth novels in general are made up of opposite characters and meaning cues. The less the student takes an interest in reading, the more he used meaning cues from outside the parent text for his anticipatory story. No doubt it would be possible to use fiction literature in the literature education to a much higher extent than it is being used today whereby the literature could be used in basic education for reviewing subject entities or study contents of other study subjects. By way of an anticipatory story and the meaning cue analysis, it is possible to intensify the educational discussions based on fiction literature. However, using fiction literature in the literature education requires consideration of the specific genre of fiction literature.

Skenaarioita käytetään usein ylimmän johdon strategiasuunnitteluvälineinä. Tämän tutkimuksen tavoitteena oli selvittää vaikuttavatko skenaariot ja skenaariotyöskentely organisaation oppimiseen laajemminkin kuin yksilötasolla ja minkälaista oppimista tapahtuu sekä minkälaisia ominaisuuksia skenaariotyötä johtavalla olisi hyvä olla. Tutkimusaineisto on kerätty haastattelemalla skenaariotöitä johtanutta henkilöä sekä niihin osallistuneita henkilöitä. Tutkittavana oli kaksi skenaariotyötä, joista toisen tavoittena oli kuvata tulevaisuuden mobiileja liiketoimintamalleja ja toisen mallintaa verkko-operaattoriliiketoiminnan tulevaisuutta. Tutkimuksen aikana selvisi, että skenaarioilla ja skenaariotyöskentelyllä voi tukea organisaation oppimista niin yksilön, ryhmän/organisaation kuin organisaatioiden väliselläkin tasolla. Skenaariotyötä tekevällä ryhmällä ja sitä johtavalla henkilöllä on vaikutusta organisaation oppimiseen. Erityisen tärkeää organisaation oppimisen kannalta on, kuinka skenaariotyöskentely aloitetaan ja lopetetaan.

The present dissertation examined reading development during elementary school years by means of eye movement tracking. Three different but related issues in this field were assessed. First of all, the development of parafoveal processing skills in reading was investigated. Second, it was assessed whether and to what extent sublexical units such as syllables and morphemes are used in processing Finnish words and whether the use of these sublexical units changes as a function of reading proficiency. Finally, the developmental trend in the speed of visual information extraction during reading was examined. With regard to parafoveal processing skills, it was shown that 2nd graders extract letter identity information approx. 5 characters to the right of fixation, 4th graders approx. 7 characters to the right of fixation, and 6th graders and adults approx. 9 characters to the right of fixation. Furthermore, it was shown that all age groups extract more parafoveal information within compound words than across adjectivenoun pairs of similar length. In compounds, parafoveal word information can be extracted in parallel with foveal word information, if the compound in question is of high frequency. With regard to the use of sublexical units in Finnish word processing, it was shown that less proficient 2nd graders use both syllables and morphemes in the course of lexical access. More proficient 2nd graders as well as older readers seem to process words more holistically. Finally, it was shown that 60 ms is enough for 4th graders and adults to extract visual information from both 4-letter and 8-letter words, whereas 2nd graders clearly needed more than 60 ms to extract all information from 8- letter words for processing to proceed smoothly. The present dissertation demonstrates that Finnish 2nd graders develop their reading skills rapidly and are already at an adult level in some aspects of reading. This is not to say that there are no differences between less proficient (e.g., 2nd graders) and more proficient readers (e.g., adults) but in some respects it seems that the visual system used in extracting information from the text is matured by the 2nd grade. Furthermore, the present dissertation demonstrates that the allocation of attention in reading depends much on textual properties such as word frequency and whether words are spatially unified (as in compounds) or not. This flexibility of the attentional system naturally needs to be captured in word processing models. Finally, individual differences within age groups are quite substantial but it seems that by the end of the 2nd grade practically all Finnish children have reached a reasonable level of reading proficiency.

The aim of this study is to contribute to the knowledge about learning in and through art related to pupils’ study processes developing clown characters in secondary school. The pre understanding of this qualitative piece of micro ethnographic research is that the elaboration of clown has openness to play, creative activity and imagination. The art form clown inspires and motivates. The clown character creates a kind and friendly atmosphere, calls upon smile, which promotes learning. It is an art form promoting deep and personal reflection and evoking questions regarding identity formation. The pre understanding finally is that existential themes are brought to articulation in the art form clown. The problem formulation for the hermeneutic phenomenological study is an exploration of the meaning potential of an arts educational work with clown from the pupils’ as well as the teacher’s perspective. The study elaborates the following research questions: 1.) How are the pupils staging themselves in the work with clown? a) How are they constructing the clown character? b) How do they reflect upon their construction? c) What are the characteristics of the working process in the elaboration of clown? 2.) What is characteristic of the teacher’s contribution to the arts educational work? 3.) What is characteristic of the meaning making in the elaboration of clown? One group of 21 pupils and their drama teacher in a Swedish secondary school in six workshops (each one 90 minutes) elaborating the clown theme is the group under study through video observation, interviews, students’ logs and drawings, teacher log and researcher’s field notes. The theoretical framework comprises three perspectives on clown: a perspective on the culture of carnival, a drama education perspective and a performance perspective. Through a content analysis of texts about clown a set of characteristics for the clown is used as analytical concepts in the subsequent analysis of the pupils’ working process when they create three clown characters: August, the white clown and the bag lady. The results are presented as fictive narratives built on the video observations and the interviews. The presentation is brought to even more condensation through poetic ethnographic writing of haiku poems by the researcher. This ethnographic writing is idiomatic to the art form under study, and can be seen as a metaphorical meta commentary to the narratives. As a main result the researcher has developed a model describing the different aspects of the clown characters and the meaning potential of the clown as learning regarding exploration of identity and elaboration of existential questions regarding life, loneliness, love, religion and death.

Diplomityön tarkoituksena oli kehittää tutkimuslaite, jolla pystyttäisiin tutkimaan sellumassan syöttötapahtumaa reikäsihdillä ja tarkastelemaan syöttöhetkellä tapahtuvaa kuituhäviötä. Laitteen suunnittelun ja valmistuksen tavoitteena oli myös saada tutkimuslaite mahdollisim-man modifioitavaksi (syöttöaukon koko, muoto ja erityyppiset reikäsihdit ja näiden vaikutukset sellukuitujen hävikkiin). Haluttiin myös mahdollisuus syöttötapahtuman kuvaamiseen esim. suurnopeuskameroin, joka otettiinkin huomioon laiteosia valittaessa (läpinäkyvä akryyli). Tutkimuslaitteen kestävyyttä erilaisissa prosessiolosuhteissa haluttiin korostaa (voidaan operoida laajalla pH ja lämpötila-alueilla, sekä syöttöpainetta voidaan muunnella). Diplomityön kirjallisuusosassa käsitellään kuituvuodon aiheuttamia haittoja, joista tärkein on taloudellinen menetys. Näiden lisäksi kirjallisuusosassa tarkastellaan pääpirteittäin pesume-netelmiä ja käydään läpi kuitusulpun suotautumiseen vaikuttavia tekijöitä. Diplomityöhön sisältyi tutkimuslaitteen suunnittelun ja valmistuksen lisäksi myös laitteen toi-mivuuden testaus. Testit suoritettiin pohjoismaisella koivusellulla. Koivusellu otettiin happi-vaiheen jälkeisen pesurin poistosta. Massalle suoritettiin KAPPA-luvun, SR-luvun, viskositee-tin ja syrjäytys -määritykset, sekä kuituanalyysi. Laitteella suoritettiin 7 %, 10 % ja 12 % sakeuksisten massojen koeajotestit. Suodokset otettiin talteen jatkotutkimuksiin, jossa niistä mitattiin kuituvuoto. 10 % suodokselle suoritettiin myös kuituanalyysi. Tuloksista nähtiin, että 7 % sakeuksinen massa antoi lähes nelinkertaisen kuituvuotomäärän 10 % sakeuksiseen massan syöttöön nähden.

This thesis studies the various forms and layers of representations of the past that can be found in the Disney comics of Don Rosa. To stay true to the legacy of renowned comic book artist Carl Barks, Rosa has stopped time in the duck universe to the 1950’s: the decade when Barks created his most noted stories. There is a special feel of historicalness in Rosa’s duck stories, as his characters recall events that occurred in both Rosa’s own stories as well as Barks’. Rosa has shed new light to the past of the characters by writing and illustrating the history of Scrooge McDuck, one of the most beloved Disney characters. Rosa is also adamant that the historical facts used in his stories are always correct and based on thorough research. The methodological tools used in the analysis of the comics come from the fields of comic book studies, film theory, and history culture. Film and comics are recognized by many scholars as very similar media, which share elements that make them comparable in many ways. This thesis utilizes studies on historical film, narrative and genre, which provide valuable insight and comparisons for analysis. The thesis consists of three main chapters, the first of which deconstructs the duck universe in the stories in order to understand how the historicalness in them is created,and which outside elements might affect them, including the genre of Disney comics, publishers, and the legacy of Barks. The next chapter focuses on The Life and Times of Scrooge McDuck series, i.e. the stories which are located in the past. Such stories feature similar representations of history as for example Westerns. They also compress and alter history to meet the restrictions of the medium of comics. The last part focuses on the adventure stories which draw inspiration from for example mythology, and take the characters to strange and mystical, but yet historical worlds. Such treasure-hunting stories show similarity to the action-adventure genre in film and for example their stereotypical representations of foreign cultures. Finally, the chapter addresses the problematic of historical fiction and its capability to write history.

Tämän työn kohdeyrityksessä ryhdyttiin syksyllä 2010 muutostoimenpiteisiin kohti lean-toimintatapaa. Nyt tavoitteena on luoda kuvaus kohdeyrityksen lean-ajattelun mukaisesta mittarointi- ja raportointitoimintatapojen käyttöönotosta pyrkien saamaan kehitystyön avulla toimintatavat tukevat jatkossa paremmin yrityksen toimintaa kohti sen visiota ja strategiaa. Työssä haluttiin erityisesti tuoda esille prosessi, jolla mittareiden ja raporttien uudistus vietiin läpi. Työ voidaan asemoida normatiiviseksi tutkimukseksi, jossa on sekä konstruktiivisen että toiminta-analyyttisen tutkimusotteiden piirteitä. Työ jakautuu teoreettiseen kirjallisuusselvitykseen sekä empiiriseen osaan, joka on tehtiin kvalitatiivisena tapaustutkimuksena. Kohdeyrityksessä vallitsevista mittarointi- ja raportointitoimintatavoista tehtiin nykytilakartoitus, jonka jälkeen yrityksestä valitulle pilottikohteelle määritettiin mittaroinnin ja raportoinnin tavoitetila. Työn merkittävin tulos on kehittämisprosessin kuvaus, joka tehdään pilottilinjalla toteutettujen muutostöiden avulla. Uuden mittariston käyttöönoton työvaiheet dokumentoitiin tarkasti, jotta samaa kehitysprosessia voidaan hyödyntää myöhemmin yrityksen muilla toiminta-alueilla. Päivitetyssä mittaristossa korostetaan sitä, kuinka esimiehen seuraamat mittarit on oltava lähtöisin yrityksen tavoitteista ja kuinka tiimitasolla on vastaavasti pyrittävä täyttämään esimiehen asettamat tavoitteet. Mittareiden tuominen linjan työntekijöiden vastuulle siirtää mittaroinnin painopistettä enemmän työntekijöille sekä lisää valittujen mittareiden seurannan merkitystä.
