Tässä diplomityössä käydään läpi lähestymistapoja sovellusintegraatioon ja niiden käyttöä yritysmaailmassa. Sovellusintegraatiolla tarkoitetaan prosessia jolla yhdistetään toimintoja tai tietoa kahdesta tai useammasta sovelluksesta ja luodaan yhtenäinen kokonaisuus toiminnallisuuksia tai tietoa. Sovellusintegraation toteuttamiseksi on olemassa erilaisia lähestymistapoja ja menetelmiä. Näillä prosesseilla pyritään linkittämään kaksi tai useampia sovelluksia toisiinsa. Sovellusintegraation avulla saadaan jo olemassa olevista järjestelmistä tietoa, pystytään hyödyntämään elektronista kaupankäyntiä, saadaan integroituja toimitusketjuja, ja saadaan jaettua tarpeelliset prosessit. Sovellusintegraatio on strateginen lähestymistapa monen tietojärjestelmän yhteensitomiseksi. Tietojen vaihto ja reaaliaikainen toiminta on tärkeää. Sovellusintegraation tuloksena käytettävissä oleva informaatio ja prosessit sisäisten- ja ulkoisten systeemien välillä tuottavat selkeää strategista etua. Työssä toteutettiin kohdeyritykselle järjestelmä jonka avulla voidaan siirtää työtunnit projektinhallintajärjestelmästä taloushallinnon järjestelmään.

Työn tavoitteena oli selvittää, millaisia muutoksia Viron, Latvian ja Liettuan rautateiden henkilöliikenteessä on tapahtunut neuvostoajan lopun ja tämän päivän välillä. Tarkastelupisteiksi valittiin vuodet 1991, 1997, 2002 ja 2009. Tutkimuksen tavoitteena oli myös selvittää muutoksiin vaikuttaneita taustatekijöitä, kuvata nykytilannetta ja tarkastella tulevaisuuden vaihtoehtoisia kehityspolkuja. Tutkimuksen tulosten perusteella rautateiden henkilöliikenteen määrä on supistunut noin puoleen kaikissa kolmessa maassa tarkasteltuna junakilometrien viikoittaisella määrällä. Matkustajamäärät ovat laskeneet kaikissa kolmessa maassa selvästi tarkastelujakson aikana. Syitä rautateiden henkilöliikenteen supistumiseen ovat olleet mm. kireä kilpailu linja-autoliikenteen kanssa ja lisääntynyt henkilöautojen käyttö. 1990-luvun taloudellisesti vaikeina vuosina rautateillä ei ollut mahdollisuuksia uusia kalustoaan. Kansainvälinen talouskriisi ja sen myötä heikentynyt taloudellinen tilanne kaikissa kolmessa maassa muodostaa uuden uhan rautateiden henkilöliikenteelle. Korkeat rataverkon käyttömaksut toimivat tehokkaana esteenä henkilöliikenteen kehittämiselle.

Tässä diplomityössä esitellään älykkäiden sähköverkkojen ominaisuuksia. Tavoitteena on selvittää, millaisia hyötyjä sähköverkkojen uudistamisella voidaan saavuttaa. Lisäksi työssä selvitetään syitä, jotka ovat ajaneet sähköverkkojen uudistamiseen. Älykäs sähkönmittaus on tärkeä osa älykkäitä sähköverkkoja, ja työssä on esitelty älykkäiden sähkömittareiden tilannetta eri maissa. Diplomityö selvittää myös hajautetun pientuotannon roolia sähköntuotannossa. Työn loppupuolella on esitelty muutama smart grid -projekti Euroopasta. Projektit valittiin Euroopasta, koska smart grids on oleellinen tekijä Euroopan komission 20/20/20 -tavoitteessa. Molemmat projektit kulminoituvat täysin älykkään sähkönmittauksen liittämiseen osaksi kuluttajien sähkönmittausta. Esimerkkien avulla nähdään, millaisella aikataululla älykkäitä sähköverkkoja saadaan aikaan ja kuinka suuria verkostokokonaisuuksia tulevaisuuden sähköverkot ovat.

The aim of this study was to examine suitability of BimTwin cleaning concept in card board machine to control microbiological activity and describe microbiological balance of the machine. In a review of literature is examined microbe and spore caused problems in paper industry. Biggest problems are deposits, which decrease runnability and cause quality errors. In this chapter is also introduced most common oxidizing biocides used in paper industry and described ATP assay as a microbiological monitoring method. In an experimental part are included BimTwin mill trial results, chemical condition monitoring methods and microbiological balance in a card board machine. In a second part are examined possibilities to effect hygiene of card board by chemical treatment of the surface size and coating. Result showed that BimTwin concept is suitable for card board machine as a cleaning concept, when chemical dosing is fitted right. For proper dosing and secure tolerable hygiene level, chemical and microbiological monitoring is significant. Determining of the microbiological balance would have need more sampling. According to acquired results, broke turned out to be the biggest microbe source. Sizing and coating experiments showed that it is possible to improve hygiene of card board by chemically treated surface size and coating color.

Selling is much maligned, often under-valued subject whose inadequate showing in business schools is in inverse proportion to the many job opportunities it offers and the importance of salespeople bringing incomes to companies. The purpose of this research is to increase the understanding of customer-oriented selling and examine the influence of customer-oriented philosophy on selling process, the applicability of selling techniques to this philosophy and the importance of them to salespeople. The empirical section of the study is two-fold. Firstly, the data of qualitative part was collected by conducting five thematic interviews among sales consultants and case company representatives. The findings of the study indicate that customer-oriented selling requires the activity of salespeople. In the customer-oriented personal selling process, salespeople invest time in the preplanning, the need analysis and the benefit demonstration stages. However, the findings propose that salespeople today must also have the basic capabilities for executing the traditional sales process, and the balance between traditional and consultative selling process will change as the duration of the relationship between the salesperson and customer increases. The study also proposes that selling techniques still belong to the customer-oriented selling process, although their roles might be modest. This thesis mapped 75 selling techniques and the quantitative part of the study explored what selling techniques are considered to be important by salespeople in direct selling industry when they make sales with new and existing customers. Response rate of the survey was 69.5%.

Marine traffic is expected to increase rapidly in the future, both in the Baltic Sea and in the Gulf of Finland. As the number of vessels in the area increases, so does the risk of serious marine accidents. To help prevent such accidents in the future, the International Maritime Organization (IMO) has put forth the International Safety Management Code (the ISM Code), which aims to improve the safety of the vessels. The second work package of the Development of maritime safety culture (METKU) project investigates the effects of the ISM Code and potential areas of improvement in maritime safety. The first phase in the work package used a literature review to determine how maritime safety culture could be improved. Continuous improvement, management commitment and personnel empowerment and motivation were found to be essential. In the second phase, shipping companies and administrators were interviewed. It was discovered that especially incident reporting based on continuous improvement was felt to be lacking. This third phase aims to take a closer look at incident reporting and suggest improvements based on the findings. Both the IMO and national legislation encourage shipping companies in incident reporting, and on the national level a shared incident reporting system (ForeSea) is being pushed forward. The objective of this research project was to find out the IMO’s attitude towards incident reporting, to establish a theoretical framework of reference in incident reporting, and to observe how reporting is actually being employed on the seas. Existing incident reporting systems were also researched. The study was carried out using a literature review and the results previously gathered in interviews. The results of phase two were elaborated further for themes relating to incident reporting. According to the findings of this research, the theoretical background of incident reporting dates back to the early 20th century. Although some theories are widely accepted, some have also received criticism. The lack of a concise, shared terminology poses major difficulties in maritime incident reporting and in determining its efficiency. A central finding is the fact that existing incident reporting focuses mostly on information flow away from the ship, whereas the backward information flow is much less planned and monitored. In incident reporting, both nationally and internationally, stakeholders are plenty. The information produced by these parties is scattered, however, and thus not very usable. Based on this research, the centralizing of this information should be made a priority. Traditionally, the success of incident reporting has been determined statistically, from the number of reported incidents. Yet existing reporting systems have not been designed with such statistical analysis in mind, so different methodologies might yield a more comprehensive view. The previous findings of seafarers and management (including shipping companies and administration) having differing views on safety work and safety management were backed up by the results of this study. Seafarers find seamanship and storytelling important, while management wants a more systematic and broad approach on safety matters. The research project was carried out by the Centre for Maritime Studies of the University of Turku, in the Kotka unit (Maritime Logistics Research), with coordination by the Kotka Maritime Research Centre. The major financiers of the project were the European Union and the city of Kotka. The financing authority was the Regional Council of Päijät-Häme. Partners in the project were the shipping companies Finnlines Oyj, Kristina Cruises Oy, Meriaura Oy and VG-Shipping Oy, and the ports of Helsinki, Kotka and Hamina. The partners provided both funding for the project and information for the research.
