Occlusal and dentofacial characteristics of the deciduous dentition and treatment effects of the eruption guidance appliance in the early mixed dentition

The aim of this investigation was to analyze the dental occlusion in the deciduous dentition, and the effects of orthodontic treatment carried out in the early mixed dentition with the eruption guidance appliance. The deciduous occlusion and craniofacial morphology of 486 children (244 girls and 242 boys) were investigated at the onset of the mixed dentition period (mean age 5.1 years, range 4.0-7.8 years). Treatment in the treatment group and follow-up in the control group were started when the first deciduous incisor was exfoliated (T1) and ended when all permanent incisors and first molars were fully erupted (T2). The mean age of the children was 5.1 years (SD 0.5) at T1 and 8.4 years (SD 0.5) at T2. Treatment was carried out with the eruption guidance appliance. Occlusal changes that took place in 167 children were compared with those of 104 untreated control children. Pre- and post-treatment cephalometric radiographs were taken, and the craniofacial morphology of 115 consecutively treated children was compared with that of 104 control children. The prevalence of malocclusion in the deciduous dentition was 68% or 93% depending on how the cut-off value between the acceptable and non-acceptable occlusal characteristic was defined. The early dentofacial features of children with distal occlusion, large overjet and deepbite differed from those with normal occlusion. However, the skeletal pattern of these three malocclusions showed considerable similarity each being characterized by a retrusive mandible, small maxillo-mandibular difference, convex profile, retrusive lower incisors, and large interincisal angle. In the treatment group, overjet and overbite decreased significantly from T1 to T2. Following treatment, a tooth-to-tooth contact was found in 99% of the treated children but only in 24% of the controls. A Class I molar relationship was observed in 90% of the children in the treatment group, and in 48% in the control group. Good alignment of the incisors was observed in 98% of the treated children, whereas upper crowding was found in 32% and lower crowding in 47% of the controls. A significant difference between the groups was found in the mandibular length, midfacial length and maxillo-mandibular differential. The occlusal correction, brought about by the eruption guidance appliance, was achieved mainly through changes in the dentoalveolar region of the mandible. In addition, the appliance seemed to enhance the growth of the mandible. Treatment in the early mixed dentition using the eruption guidance appliance is an effective method to normalize occlusion and reduce further need of orthodontic treatment. Only few spontaneous corrective changes can be expected without active intervention.

A Comparative Study on the Homeroom Teachers’ Perception of the School guidance in Korea and Finland

This study has four major purposes. First, it compares school guidance of homeroom teachers in Korea and Finland, in order to understand the reality of education, based on the teachers’ perceptions. Secondly, it also considers the topic within its historical, social, and cultural backgrounds, from a critical standpoint. Thirdly, it investigates the direction of the improvement of school guidance, based on the analysis of similarities and differences between Korea and Finland, with regards to the meaning, practice, and environmental factors of the school guidance. Lastly, the influential factors surrounding the school guidance are noted by analysing empirical data from a microscopic approach, and extending the understanding of it into a social context. As for the methods, it employs thematic analysis approach through 10 homeroom teacher interviews in the lower secondary schools. As a result, firstly, the teachers in both countries assumed similarly, that the role of the teacher was not only to teach the subject, but also to care about every aspects of the students’ development in their school life. In addition, they accepted the fact that school guidance became more significant. However, the school guidance became the top priority for the Korean teachers, while teaching subject is the main task for the Finnish teachers. Secondly, the homeroom teachers in both countries hoped to have a better working environment, to perform school guidance concerning education budget for the resources of school guidance, tight curriculum, and increasing the teachers’ tasks. Thirdly, the school guidance in Korea seemed to be influenced by social expectation and government demand, whereas, the Finnish teachers considered school guidance in more aspects of adjustment and academic motivation, rather than resolving the social problems. Fourthly, the Korean teachers perceived that the trust and respect from the society and home became weakened, also expressing doubts about the educational policies and the attitude of the government with regards to school guidance. On the other hand, the Finnish teachers believed that they were trusted and respected by the society. However, blurred lines in the roles and accountability between the homeroom teachers, home, and the society were also controversial among the teachers in both countries. To sum up, Finland needs to ameliorate the system and conditions for school guidance of the homeroom teachers. The consensus on the role and tasks of Finnish homeroom teachers for school guidance seem to be also necessary. Meanwhile, Korea should improve the social system and social consciousness of the teacher, school guidance, and schooling, preceding the reform of the education system or conditions.

Katepillarista kauppakassiin : product placement suomalaisessa tv-ohjelmatuotannossa

Product placement has become more and more common in Finnish television programmes lately. Product placement, as with the whole of the television industry, is strictly regulated and monitored by law. Surreptitious advertising, sponsorship, cooperative partnerships and product placement are often confused with each other. Partially these activities are interpenetrative. Present legislation doesn't recognise product placement, therefore it doesn't have any specific position in law, thus causing problems. Product placement in domestic tv-programmes is still relatively modest. More extensive activity is perceivable at the movies where the restrictions are considerably more liberal. In the United States, product placement is a part of a production's budget. Pressure to increase financing has grouwn in both Finland and Europe. There has been considerable preparation in advance of a new television directive in the European Union which would allow more liberal advertising and product placement as a part of financing tv-programmes. The proposal for a new directive is currently only on its first round so product placement probably won't become better defined in law in the near future. Finnish television producers were interviewed as part of the research for this thesis, in order to clarify product placement position and usage in domestic televion programmes. Surreptitious advertising, sponsorship, different kinds of cooperative partnerships and the need for guidance were also discussed in the course of the themed interviews. Even though product placement does not currently play a significant part in the financing of a production, there are certainly pressures in that direktion. In the field of television, the legal boundaries of product placement are presently being explored in order to assess its position as a part of budgeting and covering expenses.

ATS3-testausjärjestelmän evaluointi

Työ tehtiin Nokia Technology Platforms S60 Mobile Runtime-yksikölle. Työn tavoitteena oli evaluoida ATS3-testausjärjestelmä. ATS3-järjestelmällä voidaan automatisoida ohjelmistotestausta. Evaluoinnilla pyrittiin selvittämään voidaanko tuotekehitysvaiheessa oleva järjestelmä ottaa jo käyttöön vai vaatiiko se vielä lisäkehitystä. Työssä kerrotaan aluksi yleisesti ohjelmistotestauksesta. Siinä käydään läpi myös testausprosessin vaiheet sekä kerrotaan lyhyesti avuksi kehitetyistä työkaluista. Työssä kerrotaan myös ATS3-järjestelmän edeltäjien ominaisuuksista, sekä miten ne eroavat tarkastelun kohteena olevasta järjestelmästä. Varsinainen evaluointi alkoi tutustumalla ja asentamalla järjestelmä. Tämän jälkeen suoritettiin samat testit sekä ATS2.x-järjestelmässä että ATS3-järjestelmäss. Testauksen jälkeen analysoitiin testitulosten yhdenmukaisuuden perusteella, voidaanko siirtyä käyttömään ATS3-järjestelmää. Testitulokset olivat käytännässä yhdenmukaiset suoritettaessa testejä matkapuhelimessa, mutta emulaattoritestaus täytyi jättää väliin. Lukuisista yrityksistä sekä järjestelmän kehittäjän avusta huolimatta testejä ei onnistuttu suorittamaan ATS3-järjestelmän emulaattoriympäristössä. Näin ollen päädyttiin tulokseen, ettei järjestelmää voida ottaa vielä käytöön emulaattoritestauksessa, vaan se vaatii lisätutkimusta sekä perehtymistä järjestelmään.

ACS800-kaappimoduulien pakkaamon ulkoistaminen

Tässä insinöörityössä selvitetään ABB Oy System AC -liiketoimintayksikön pakkaamon ulkoistamiseen liittyviä ongelmia sekä mahdollisia ratkaisuja näihin ongelmiin. Koko ongelman käsittely on liian laaja projektin yhdelle insinöörityölle. Tässä työssä keskitytään ratkaisemaan ko. ulkoistamiseen liittyvät keskeisimmät ACS800-kaappimoduulien kuljetuslogistiset ongelmat. Näitä ongelmia ovat kaappimoduulien kiinnitystarve kuljetusalustaansa sekä kuljetuspaketoinnin puuttuessa kaappimoduulien suojaaminen maantiekuljetuksen ajaksi. Työssä on otettu huomioon viranomaisten maantiekuljetuksia koskevat vaatimukset. Työssä on suunniteltu uusia kiinnitysvälineitä sekä muutoksia olemassa oleviin kuljetusalustoihin, joita käytetään tehtaan sisäisissä kaappimoduulien siirroissa. Kiinnitysvälineistä on tehty lujuuslaskelmia ja määritelty kiristysmomentteja. Tuotettavuuden ja kustannustehokkuuden kannalta on selvitetty kiinnitysvälineisiin soveltuvia materiaalivaihtoehtoja. Kuljetusalustojen muutoksista on myös tehty ohjeistusta. Tämän työn tulos on uusien kiinnitysvälineiden ja kuljetusalustojen mekaanisten muutosten suunnittelu. Samalla on todistettu, että kaappimoduulien siirto tehtaan ulkopuoliseen pakkaamoon ilman kuljetuspaketointia on teoriassa mahdollista.
