Kunnissa eletään muutosten aikaa, ja osaamisen johtamisella pyritään vastaamaan kehityksen mukanaan tuomiin haasteisiin. Osaamisen johtamista pidetäänkin tärkeänä asiana kuntien kehittämisessä. Viime vuosina osaamisen johtaminen on ollut voimakkaasti esillä myös yksityisellä sektorilla, jossa se on nähty tärkeänä elementtinä kilpailukyvyn kehittämisessä. Osaamisen johtaminen on toimintaa, jolla kehitetään yksilöiden ja organisaation osaamista sekä organisaation yhteistyövalmiutta. Osaamisen johtamisessa huomioidaan myös organisaatiolle asetetut strategiset tavoitteet. Tässä tutkimuksessa osaamisen johtaminen ankkuroidaan tietojohtamisen, henkilöstövoimavarojen johtamisen (HRM:n) ja oppivan organisaation viitekehyksiin. Tutkimusotteeksi on valittu kvantitatiivinen tutkimusote. Kvantitatiivinen tutkimusote mahdollistaa osaamisen johtamisen rakenteellisen analyysin ja kuvaamisen. Tutkimuksen kohderyhmänä ovat kaikki Suomen 444 kuntaa vuonna 2004. Tutkimuksen tiedonkeruu suoritettiin lomakekyselyn avulla, ja tutkimus kohdistettiin kuntien henkilöstöasioiden asiantuntijoille. Tutkimuksen keskeisenä tavoitteena oli mallintaa ja kuvata osaamisen johtamista Suomen kunnissa. Tutkimusongelma liittyy kuntien osaamisen johtamisen nykytilaan ja tavoitteisiin sekä siihen, missä vaiheissa kunnat ovat osaamisen johtamisessaan. Kyselyn avulla tutkittiin myös kuntien halukkuutta kehittää osaamisen johtamistaan. Vastausten pohjalta analysoitiin lisäksi, mitkä asiat kunnissa vaikuttavat osaamisen johtamiseen. Tutkimuksen tuloksissa tulevat esille neljä erilaista kunnissa vallitsevaa osaamisen johtamisen orientaatiota: Strategiaohjattu yhteisöllinen orientaatio, Innovatiivinen orientaatio, Teknologinen orientaatio ja Strategialähtöinen järjestelmäorientaatio. Nämä neljä orientaatiota ovat tunnistettavissa myös taustakirjallisuudessa. Kunnat ryhmiteltiin orientaatioiden perusteella neljään ryhmään, jotka nimettiin seuraavasti: Innostuneet aloittelijat, Tekniset aloittelijat, Edistyneet ja Kehittyvät. Innostuneiden aloittelijoiden ryhmässä korostuu innovatiivinen orientaatio, mutta muut osaamisen johtamisen orientaatiot tulevat esille heikosti. Teknisten aloittelijoiden ryhmässä korostuu teknologinen orientaatio, mutta muut osaamisen johtamisen orientaatiot tulevat esille heikosti. Edistyneiden ryhmässä kaikki osaamisen johtamisen orientaatiot tulevat hyvin esille. Kehittyvien ryhmässä korostuvat sekä innovatiivinen että teknologinen orientaatio. Kuntien osaamisen johtamisen nykytilanne on murroksessa. Osaamisen johtaminen on suuressa osassa kunnista hyvässä vauhdissa, mutta kehitettävääkin on. Tietotekniset välineet osaamisen johtamisessa ovat hyvät useimmissa kunnissa. Tulevaisuuden osaamistarpeina pidetään erityisesti vuorovaikutustaitoja ja oman ammattialan osaamista. Kunnissa on myös huomioitu ainakin tavoitteiden tasolla tulevaisuus ja sen tuomat haasteet.

Virtuaaliset yhteisöt ja erilaiset virtuaaliset välineet yhteisöllisyyden mahdollistamiselle ovat kasvavan tieteellisen mielenkiinnon kohteena. Tässä tutkimuksessa tutkittiin uuden tiedon luomisen prosessia blogiviestinnässä. Tämä tehtiin käyttäen tietojohtamisen tieteenalalla perusteoriana pidettyä Ikujiro Nonakan uuden tiedon luomisen SECImalliia. Blogiympäristöä tarkasteltiin niin ikään Ikujiro Nonakan bakäsitteen avulla. Aihetta tarkennettiin pohtimalla ryhmäytymistä ja sen ilmenemistä virtuaalisessa viestinnässä. Tutkimus toteutettiin tapaustutkimuksena, ja tutkimuskohteena oli Lappeenrannan teknillisen yliopiston opintojaksolla ”Virtuaalinen yhteistyö ja tietotekniset työkalut” käytetty verkko-oppimissovelluksen tarjoama blogialusta. Tutkimuksen empiirisen osan muodostaa aineisto, joka rakentuu opiskelijoiden omista opintojaksoon kuuluvista blogikeskusteluista. Tutkimuksen tärkeimpänä johtopäätöksenä havaittiin, että blogiviestintä edistää uuden tiedon luomista. Edelleen todettiin että blogialusta tukee välineenä uuden tiedon luomisen prosessia, ja tarjoaa tiedon luomiselle hyvän virtuaalisen ympäristön, ba:n. Uuden tiedon luomiseen vaikutti luottamus niin teknistä alustaa, opettajia kuin yhteisöä kohtaan. Avaintekijöiksi nousi avoimuus, tahto jakaa omaa tietämystään, mielenkiinto aiheeseen sekä ryhmäkoheesio. Uuden tiedon rakentumisen huomaaminen, ja virtuaalisen yhteisön uuden tiedon luomisen potentiaalin ymmärtäminen nostivat kollektiivisesti tahtoa rikastaa yleistä keskustelua, heijastaa omia kokemuksia muiden kokemuksiin, sekä jakaa yhteiset johtopäätökset, eli sosiaalistaa, ulkoistaa, yhdistää ja sisäistää kollektiivisesti luotu tieto yksilön kokemukseksi.

Tämä diplomityö käsittelee kartonginmuovaukseen käytettävien puristintyökalujen kehittämistä. Työntavoitteina oli kehittää työkalutekniikan suunnittelua ja valmistusta edullisemmaksi, nopeammaksi ja työkaluja toiminnoiltaan tehokkaammiksi. Työn tuli sisältää myös ohjeet työkalujen suunnittelemiseksi ja valmistamiseksi jatkoa ajatellen. Työn aikana selvitettiin mahdollisia työkalurakennevaihtoehtoja, valmistusmateriaaleja sekä niiden käsittelymenetelmiä ja lastuamista sekä sen tarjoamia mahdollisuuksia valmistusmenetelmänä. Työkalupari suunniteltiin modulaariseksi siten, että uusia työkaluja varten vain osa komponenteista täytyy valmistaa uudelleen, samalla työkalun osien lukumäärää pienennettiin merkittävästi. Valmistusmateriaaliksi valittiin hyvin lastuttava työkaluteräs ja sen koneistaminen tapahtui vaakakaraisessa koneistuskeskuksessa. Työn loppuvaiheessa työkalukokonaisuudelle tehtiin kustannuslaskelma jaoteltuna eri työvaiheille sekä komponenteittain. Työkalu asennettiin puristimeen ja sille suoritettiin käyttötestaus. Työn aikana karttuneen kokemuksen sekä koekäytön perusteella tehtiin jatkokehitysehdotuksia.

Tutkimuksen tavoitteena oli selvittää sisäisen kommunikoinnin tilannetta case-yrityksissä. Yritykset kuuluvat kahteen case-arvoverkostoon, jotka toimivat informaatio- ja kommunikaatioteknologian alalla. Sisäinen kommunikointi valittiin tutkimusalueeksi, koska se muodostaa perustan ulkoiselle, yritysten väliselle kommunikoinnille. Tutkimuksen painopiste oli web-pohjaisessa kommunikoinnissa ja webin ominaisuuksissa arvoverkoston näkökulmasta. Tutkimusprosessissa käytettiin sekä kvalitatiivisia että kvantitatiivisia menetelmiä. Tutkimuksen kvantitatiivinen osa toteutettiin web-kyselynä, jonka tulokset osoittivat, että case-yritysten sisäinen kommunikointi perustuu pääasiassa perinteisten kommunikointivälineiden käyttöön. Toisin sanoen, webin hyödyntäminen on vähäistä, mihin vaikuttavat monet eri tekijät. Webissä on kuitenkin useita ominaisuuksia, jotka parantavat kommunikointia arvoverkostossa ja siksi nämä web-pohjaiset välineet tulisi huomioida, kun suunnitellaan yleistä kommunikointijärjestelmää. Tutkimuksen teoreettisessa osassa määriteltiin vuorovaikutteisuus-ominaisuuteen perustuva kommunikointivälineiden luokittelu. Tämän lisäksi määriteltiin myös arvoverkoston käsite. Empiirinen osa koostui web-kyselyn toteutuksen ja tulosten raportoinnista, jonka jälkeen yhteenvetokappale koosti merkittävimmät havainnot sekä mahdolliset jatkotutkimusaiheet.

Työn tavoitteena on selvittää palvelutasosopimuksella ja sen hallinnalla saatavaa hyötyä toimittajan hallinnassa. Tutkimusongelmaa on lähdetty selvittämään tutustumalla ensin lyhyesti toimittajan hallintaan ja laajemmin palvelutasosopimuksista ja niiden hallinnasta olemassa olevaan teoria-aineistoon. Tämän teoriapohjan perusteella palvelutasosopimuksia ja niiden hallintaa on tutkittu käytännössä case-yrityksen valossa, mahdollisimman realistiseen lopputulokseen pääsemiseksi. Palvelujen ulkoistaminen tulee tulevaisuudessa lisääntymään ja tätä kautta yritysten onnistuminen markkinoilla on yhä riippuvaisempaa niiden kyvystä hallita toimittajiaan. Palvelutasosopimukset ja prosessit niiden ympärillä ovat hyödyllisiä työkaluja toimittajan suorituksen valvonnassa ja kehittämisessä sekä toimittajasuhteen luotsaamisessa kohti kumppanuussuhdetta. Tämä edellyttää kuitenkin, että kauppakumppanit sisäistävät palvelutasosopimusten kautta saavutettavat hyödyt ja sitoutuvat koko palvelutason hallintaprosessiin.

This thesis analyses the calculation of FanSave and PumpSave energy saving tools calculation. With these programs energy consumption of variable speed drive control for fans and pumps can be compared to other control methods. With FanSave centrifugal and axial fans can be examined and PumpSave deals with centrifugal pumps. By means of these programs also suitable frequency converter can be chosen from the ABB collection. Programs need as initial values information about the appliances like amount of flow and efficiencies. Operation time is important factor when calculating the annual energy consumption and information about it are the length and profile. Basic theory related to fans and pumps is introduced without more precise instructions for dimensioning. FanSave and PumpSave contain various methods for flow control. These control methods are introduced in the thesis based on their operational principles and suitability. Also squirrel cage motor and frequency converter are introduced because of their close involvement to fans and pumps. Second part of the thesis contains comparison between results of FanSave’s and PumpSave’s calculation and performance curve based calculation. Also laboratory tests were made with centrifugal and axial fan and also with centrifugal pump. With the results from this thesis the calculation of these programs can be adjusted to be more accurate and also some new features can be added.

This thesis concentrates on studying the operational disturbance behavior of machine tools integrated into FMS. Operational disturbances are short term failures of machine tools which are especially disruptive to unattended or unmanned operation of FMS. The main objective was to examine the effect of operational disturbances on reliability and operation time distribution for machine tools. The theoretical part of the thesis covers the fimdamentals of FMS relating to the subject of this study. The concept of FMS, its benefits and operator's role in FMS operation are reviewed. The importance of reliability is presented. The terms describing the operation time of machine tools are formed by adopting standards and references. The concept of failure and indicators describing reliability and operational performance for machine tools in FMSs are presented. The empirical part of the thesis describes the research methodology which is a combination of automated (ADC) and manual data collection. By using this methodology it is possible to have a complete view of the operation time distribution for studied machine tools. Data collection was carried out in four FMSs consisting of a total of 17 machine tools. Each FMS's basic features and the signals of ADC are described. The indicators describing the reliability and operation time distribution of machine tools were calculated according to collected data. The results showed that operational disturbances have a significant influence on machine tool reliability and operational performance. On average, an operational disturbance occurs every 8,6 hours of operation time and has a down time of 0,53 hours. Operational disturbances cause a 9,4% loss in operation time which is twice the amount of losses caused by technical failures (4,3%). Operational disturbances have a decreasing influence on the utilization rate. A poor operational disturbance behavior decreases the utilization rate. It was found that the features of a part family to be machined and the method technology related to it are defining the operational disturbance behavior of the machine tool. Main causes for operational disturbances were related to material quality variations, tool maintenance, NC program errors, ATC and machine tool control. Operator's role was emphasized. It was found that failure recording activity of the operators correlates with the utilization rate. The more precisely the operators record the failure, the higher is the utilization rate. Also the FMS organizations which record failures more precisely have fewer operational disturbances.

The use of domain-specific languages (DSLs) has been proposed as an approach to cost-e ectively develop families of software systems in a restricted application domain. Domain-specific languages in combination with the accumulated knowledge and experience of previous implementations, can in turn be used to generate new applications with unique sets of requirements. For this reason, DSLs are considered to be an important approach for software reuse. However, the toolset supporting a particular domain-specific language is also domain-specific and is per definition not reusable. Therefore, creating and maintaining a DSL requires additional resources that could be even larger than the savings associated with using them. As a solution, di erent tool frameworks have been proposed to simplify and reduce the cost of developments of DSLs. Developers of tool support for DSLs need to instantiate, customize or configure the framework for a particular DSL. There are di erent approaches for this. An approach is to use an application programming interface (API) and to extend the basic framework using an imperative programming language. An example of a tools which is based on this approach is Eclipse GEF. Another approach is to configure the framework using declarative languages that are independent of the underlying framework implementation. We believe this second approach can bring important benefits as this brings focus to specifying what should the tool be like instead of writing a program specifying how the tool achieves this functionality. In this thesis we explore this second approach. We use graph transformation as the basic approach to customize a domain-specific modeling (DSM) tool framework. The contributions of this thesis includes a comparison of di erent approaches for defining, representing and interchanging software modeling languages and models and a tool architecture for an open domain-specific modeling framework that e ciently integrates several model transformation components and visual editors. We also present several specific algorithms and tool components for DSM framework. These include an approach for graph query based on region operators and the star operator and an approach for reconciling models and diagrams after executing model transformation programs. We exemplify our approach with two case studies MICAS and EFCO. In these studies we show how our experimental modeling tool framework has been used to define tool environments for domain-specific languages.

Prostate-specific antigen (PSA) is a marker that is commonly used in estimating prostate cancer risk. Prostate cancer is usually a slowly progressing disease, which might not cause any symptoms whatsoever. Nevertheless, some cases of cancer are aggressive and need to be treated before they become life-threatening. However, the blood PSA concentration may rise also in benign prostate diseases and using a single total PSA (tPSA) measurement to guide the decision on further examinations leads to many unnecessary biopsies, over-detection, and overtreatment of indolent cancers which would not require treatment. Therefore, there is a need for markers that would better separate cancer from benign disorders, and would also predict cancer aggressiveness. The aim of this study was to evaluate whether intact and nicked forms of free PSA (fPSA-I and fPSA-N) or human kallikrein-related peptidase 2 (hK2) could serve as new tools in estimating prostate cancer risk. First, the immunoassays for fPSA-I and free and total hK2 were optimized so that they would be less prone to assay interference caused by interfering factors present in some blood samples. The optimized assays were shown to work well and were used to study the marker concentrations in the clinical sample panels. The marker levels were measured from preoperative blood samples of prostate cancer patients scheduled for radical prostatectomy. The association of the markers with the cancer stage and grade was studied. It was found that among all tested markers and their combinations especially the ratio of fPSA-N to tPSA and ratio of free PSA (fPSA) to tPSA were associated with both cancer stage and grade. They might be useful in predicting the cancer aggressiveness, but further follow-up studies are necessary to fully evaluate the significance of the markers in this clinical setting. The markers tPSA, fPSA, fPSA-I and hK2 were combined in a statistical model which was previously shown to be able to reduce unnecessary biopsies when applied to large screening cohorts of men with elevated tPSA. The discriminative accuracy of this model was compared to models based on established clinical predictors in reference to biopsy outcome. The kallikrein model and the calculated fPSA-N concentrations (fPSA minus fPSA-I) correlated with the prostate volume and the model, when compared to the clinical models, predicted prostate cancer in biopsy equally well. Hence, the measurement of kallikreins in a blood sample could be used to replace the volume measurement which is time-consuming, needs instrumentation and skilled personnel and is an uncomfortable procedure. Overall, the model could simplify the estimation of prostate cancer risk. Finally, as the fPSA-N seems to be an interesting new marker, a direct immunoassay for measuring fPSA-N concentrations was developed. The analytical performance was acceptable, but the rather complicated assay protocol needs to be improved until it can be used for measuring large sample panels.

In the Innovation Union Scoreboard of 2011, Latvia ranked last amongst the EU countries in innovation performance. Even though there is sufficient scientific and technological basis, the results remain modest or low in most of the indicators concerning innovations. Several aspects influence the performance a national innovation system. In Latvia, the low effectiveness is often attributed to lack of financial support tools. As a comparison, Finland was chosen because of its well-established and documented innovation system. The aim of this study is to research the efficiency and effectiveness of the current financial innovation support tool system in Latvia from the point of view of an innovating company. It also attempts to analyze the support tool system of Latvia and compare to the relevant parts of the Finnish system. The study found that it is problematic for innovative companies in Latvia to receive the necessary funding especially for start-ups and SMEs due to the low number of grant programs, funds and lacking offer from banks, venture capital and business angels. To improve the situation, the Latvian government should restructure the funding mechanisms putting a bigger emphasis on innovative start-ups and SMEs. That would lay a foundation for future growth and boost research and scientific activities in Latvia.

The current research emphasizes on various questions raised and deliberated upon by different entrepreneurs. It provides a valuable contribution to comprehend the importance of social media and ICT-applications. Furthermore, it demonstrates how to support and implement the management consulting and business coaching start-ups with the help of social media and ICT-tools. The thesis presents a literary review from different information systems science, SME and e-business journals, web articles, as well as, survey analysis reports on social media applications. The methodology incorporated into a qualitative research method in which social anthropological approaches were used to oversee the case study activities in order to collect data. The collaborative social research approach was used to shelter the action research method. The research discovered that new business start-ups, as well as small businesses do not use social media and ICT-tools, unlike most of the large corporations use. At present, the current open-source ICT-technologies and social media applications are equally available for new and small businesses as they are available for larger companies. Successful implementation of social media and ICT-applications can easily enhance start-up performance and overcome business hassles. The thesis sheds some light on effective and innovative implementation of social media and ICT-applications for new business risk takers and small business birds. Key words

The last decade has shown that the global paper industry needs new processes and products in order to reassert its position in the industry. As the paper markets in Western Europe and North America have stabilized, the competition has tightened. Along with the development of more cost-effective processes and products, new process design methods are also required to break the old molds and create new ideas. This thesis discusses the development of a process design methodology based on simulation and optimization methods. A bi-level optimization problem and a solution procedure for it are formulated and illustrated. Computational models and simulation are used to illustrate the phenomena inside a real process and mathematical optimization is exploited to find out the best process structures and control principles for the process. Dynamic process models are used inside the bi-level optimization problem, which is assumed to be dynamic and multiobjective due to the nature of papermaking processes. The numerical experiments show that the bi-level optimization approach is useful for different kinds of problems related to process design and optimization. Here, the design methodology is applied to a constrained process area of a papermaking line. However, the same methodology is applicable to all types of industrial processes, e.g., the design of biorefiners, because the methodology is totally generalized and can be easily modified.

The starting point of this study is that the prevailing way to consider the Finnish IT industries and industry information often results in a limited and even skewed picture of the sector. The purpose of the study is to contribute and increase knowledge and understanding of the status, structure and evolution of the Finnish IT industries as well as the Finnish IT vendor field and competition. The focus is on software product and IT services industries which form a crucial part of all ICT industries. This study examines the Finnish IT sector from production (supply) as well as market (demand) perspective. The study is based on empirical information from multiple sources. Three research questions were formulated for the study. The first concerns the status of the Finnish IT industries considered by applying theoretical frameworks. The second research question targets at the basis for the future evolution of the Finnish IT industries and, finally, the third at the ability of the available definitions and indicators to describe the Finnish IT industries and IT markets. Major structural changes like technological changes and related innovations, globalization and new business models are drivers of the evolution of the IT industries. The findings of this study emphasize the significant role of IT services in the Finnish IT sector and in connection to that the ability to combine IT service skills, competences and practices with high level software skills also in the future. According to the study the Finnish IT enterprises and their customers have become increasingly dependent on global ecosystems and platforms, applications and IT services provided by global vendors. As a result, more IT decisions are made outside Finland. In addition, IT companies are facing new competition from other than IT industries bringing into market new substitutes. To respond to the new competition, IT firms seek growth by expanding beyond their traditional markets.. The changing global division of labor accentuates the need for accurate information of the IT sector but, at the same time, also makes it increasingly challenging to acquire the information needed. One of the main contributions of this study is to provide frameworks for describing the Finnish IT sector and its evolution. These frameworks help combine empirical information from various sources and make it easier to concretize the structures, volumes, relationships and interaction of both, the production and market side of the Finnish IT industry. Some frameworks provide tools to analyze the vendor field, competition and the basis for the future evolution of the IT industries. The observations of the study support the argument that static industry definitions and related classifications do not serve the information needs in dynamic industries, such as the IT industries. One of the main messages of this study is to emphasize the importance of understanding the definitions and starting points of different information sources. Simultaneously, in the structure and evolution of Finnish IT industries the number of employees has become a more valid and reliable measure than the revenue based indicators.
