Integration of Electronic Commerce and Enterprise Systems

The necessity of EC (Electronic Commerce) and enterprise systems integration is perceived from the integrated nature of enterprise systems. The proven benefits of EC to provide competitive advantages to the organizations force enterprises to adopt and integrate EC with their enterprise systems. Integration is a complex task to facilitate seamless flow of information and data between different systems within and across enterprises. Different systems have different platforms, thus to integrate systems with different platforms and infrastructures, integration technologies, such as middleware, SOA (Service-Oriented Architecture), ESB (Enterprise Service Bus), JCA (J2EE Connector Architecture), and B2B (Business-to-Business) integration standards are required. Huge software vendors, such as Oracle, IBM, Microsoft, and SAP suggest various solutions to address EC and enterprise systems integration problems. There are limited numbers of literature about the integration of EC and enterprise systems in detail. Most of the studies in this area have focused on the factors which influence the adoption of EC by enterprise or other studies provide limited information about a specific platform or integration methodology in general. Therefore, this thesis is conducted to cover the technical details of EC and enterprise systems integration and covers both the adoption factors and integration solutions. In this study, many literature was reviewed and different solutions were investigated. Different enterprise integration approaches as well as most popular integration technologies were investigated. Moreover, various methodologies of integrating EC and enterprise systems were studied in detail and different solutions were examined. In this study, the influential factors to adopt EC in enterprises were studied based on previous literature and categorized to technical, social, managerial, financial, and human resource factors. Moreover, integration technologies were categorized based on three levels of integration, which are data, application, and process. In addition, different integration approaches were identified and categorized based on their communication and platform. Also, different EC integration solutions were investigated and categorized based on the identified integration approaches. By considering different aspects of integration, this study is a great asset to the architectures, developers, and system integrators in order to integrate and adopt EC with enterprise systems.

Key factors in transforming university internationalization into commercial activity in Finland. Case of University of Turku

Globalization, developments in ICT, emergence of knowledge society and other changes have reformed the environment for international higher education during the past few decades. Consequently, higher education sector has moved towards more marketing-oriented system, and universities have started to undertake commercial activities as part of their internationalization. This development has emerged to Finland as well, which forms the basis for this study. The purpose is to examine commercialization in Finnish university landscape and to investigate the ways Finnish university could capitalize its international activities and educational knowledge for export. The research question of the study is: What are the key factors in transforming university internationalization into commercial activity in the Finnish university landscape? The main problem is further divided into three sub-questions: 1) How can a university internationalize; 2) what are the motivational factors behind university internationalization and commercialization; and 3) how can higher education be developed into export services and products? The research was conducted as a qualitative case study of University of Turku. Methods used for gathering and examining data were interviewing and document analysis. Primary data was collected through four individual semi-structured interviews, which were conducted face-to-face. Secondary data that included reports, articles and electronic materials such as university web pages, was used to complement the primary data. The results were analyzed by theming the data into three broader categories of internationalization activities; drivers and motivations and; education export activities. After the data was organized in themes, analysis continued by comparing different parts of data and finding patterns that would explain the phenomenon in Finnish universities. According to the empirical data, University of Turku is currently on the growth state of internationalization with strategies such as internationalization of curriculum, establishment of international research groups, mobility of students and academics, international networking and support services. Commercialization phenomenon is still rather new to the case university, but it has already developed educational products and services for export. The study concludes that university internationalization cannot be directly transformed into commercial activities in the Finnish context, but the universities need to be active in actually creating educational products. The key factors found in this study include: 1) the Finnish government policies behind the current hype of export education; 2) the potential and knowledge capacity of universities for exports; 3) need for additional profits; 4) further internationalization through commercial activities; 5) recognizing and exploiting the specific areas of strength and 6) establishing of cooperative partnerships for better products.

Potential utilization ways of recovered chemical products from digestate

The study evaluates the potential application of chemical substances, obtained from biogas plants` by-products. Through the anaerobic digestion process with biogas the large amount of digestate is produced. This digestate mainly consists on the organic matter with the high concentration of nutrients such as nitrogen and phosphorus. During ammonia stripping and phosphorus precipitation the products- ammonia water, ammonium sulfate, ammonium nitrate, ferrous phosphate, aluminum phosphate, calcium phosphate and struvite can be recovered. These chemicals have potential application in different industrial sectors. According to Finnish market and chemicals properties, the most perspective industrial applications were determined. Based on the data, obtained through the literature review and market study, the ammonia water was recognized as a most perspective recovered substances. According to interview provided among Finnish companies, ammonia water is used for flue gas treatment in SNCR technology. This application has a large scale in the framework of Finnish industrial sectors. As well nitrogen with phosphorous can be used as a source of nutrients in the biological wastewater treatment plants of paper mills.

Backpacker 2.0 - Contemporary backpackers and their use of social media as an information and communication platform

Long-term independent budget travel to countries far away has become increasingly common over the last few decades, and backpacking has now entered the tourism mainstream. Nowadays, backpackers are a very important segment of the global travel market. Backpacking is a type of tourism that involves a lot of information search activities. The Internet has become a major source of information as well as a platform for tourism business transactions. It allows travelers to gain information very effortlessly and to learn about tourist destinations and products directly from other travelers in the form of electronic word-of-mouth (eWOM). Social media has penetrated and changed the backpacker market, as now modern travelers can stay connected to people at home, read online recommendations, and organize and book their trips very independently. In order to create a wider understanding on modern-day backpackers and their information search and share behavior in the Web 2.0 era, this thesis examined contemporary backpackers and their use of social media as an information and communication platform. In order to achieve this goal, three sub-objectives were identified: 1. to describe contemporary backpacker tourism 2. to examine contemporary backpackers’ travel information search and share behavior 3. to explore the impacts of new information and communications technologies and Web 2.0 on backpacker tourism The empirical data was gathered with an online survey, thus the method of analysis was mainly quantitative, and a qualitative method was used for a brief analysis of open questions. The research included both descriptive and analytical approaches, as the goal was to describe modern-day backpackers, and to examine possible interdependencies between information search and share behavior and background variables. The interdependencies were tested for statistical significance with the help of five research hypotheses. The results suggested that backpackers no longer fall under the original backpacker definitions described some decades ago. Now, they are mainly short-term travelers, whose trips resemble more those of mainstream tourists. They use communication technologies very actively, and particularly social media. Traditional information sources, mainly guide books and recommendations from friends, are of great importance to them but also eWOM sources are widely used in travel decision making. The use of each source varies according to the stage of the trip. All in all, Web 2.0 and new ICTs have transformed the backpacker tourism industry in many ways. Although the experience has become less authentic in some travelers’ eyes, the backpacker culture is still recognizable.

Distribution channel plan for wound care products: Case 3M Finland Ltd.

The aim of this master’s thesis was to make a qualitative marketing research and on the basis of this to develop a distribution plan for the case company Finnish 3M Ltd.’s wound care products. The literature review includes three important parts: distribution channel planning, the buying behavior of seniors, and special characteristics of health care products’ marketing. The empirical part of this thesis comprises two different parts. The first part is a marketing research, in which the buying behavior of wound care products is studied in Espoo. The research aim was to examine, in which distribution channels the wound care patients under home care would most preferably buy wound care products during the time period, when municipalities will not yet provide the products for free. The data was collected through semi-structured phone interviews and regular interviews, and was treated qualitatively and anonymously. The study revealed that the recommendations of nurses and doctors influenced most the buying behavior of wound care customers. In the second part of the thesis a distribution channel plan for wound care products was made for the case company 3M Finland Ltd. based on the results. 3M Finland Ltd. should focus on pharmacies, online-stores and municipal health centers as their main distributors.

The requirements of a feasible plastic packaging material for cultured dairy products

The objective of this Master´s Thesis was to conduct a wide scale preliminary survey regarding the package requirements of a cultured dairy package, and to compare the currently used material polystyrene to other suitable packaging materials. Polystyrene has a long history of use in dairy cups, but in recent years its price has increased significantly compared to other common packaging materials. The overall environmental effects of a package and a package material are today a part of designing a sustainable product life cycle. In addition, in certain contexts there has been discussion of the risks posed by styrene polymer for the environment and for humans. These risks are also discussed in this thesis. Polystyrene (PS) is still the most widely used material in dairy cups. In recent years, polypropylene (PP) cups have appeared in increasing numbers on market shelves. This study focuses on the differences of the suitable polymers and examines the suitability of alternative “suitable” polymers with regards to dairy packaging. Aside from focusing on the cup manufacturer, this thesis also examines its subject matter from the viewpoint of the dairy customer, as well as observing the concrete implications of material changes in the overall value chain. It was known in advance that material permeability would be one of the determining factors and that gas transmission testing would be a significant part of the thesis. Mechanical tests were the second part of the testing process, providing information regarding package strength and protectiveness during the package’s life cycle. Production efficiency, along with uninterrupted stable production, was another important factor that was taken into consideration. These two issues are sometimes neglected in similar contexts due to their self-evident nature. In addition, materials used in production may have a surprising significance to the production and efficiency. Consistent high quality is also partly based on material selection. All of the aforementioned factors have been documented and the results have been analyzed by the development team at Coveris Rigid Finland. Coveris is now calculating the total finance effects and capacities should the material changes be implemented in practice. There are many factors in favor of switching to polypropylene at the moment. The overall production costs, as well as the environmental effects of resin production are the primary influences for said switch from the converters’ perspective.

Imbuing airborne electronic warfare self-protection : possibilities to disguise

Tutkielman nimi käännettynä suomeksi on Lentokoneiden omasuojajärjestelmien kyllästäminen – mahdollisuuksia kätkeytymiseen. Siinä keskitytään etsimään aktiivisia, ilmauhkaa kohti säteileviä keinoja ilmahyökkääjän, lentokoneen tai helikopterin, omasuojajärjestelmän harhauttamiseksi. Järjestelmät pyrkivät varoittamaan lentäjää laser- ja tutkasäteilyhavainnoista sekä ohjuksen laukaisusta ja lähestymisestä. Omasuojajärjestelmiin kuuluviin vastakeinoihin tutkimus ei keskity. Tavoitteena harhauttamisella on ilmapuolustuksen todellisen määrän ja sijainnin suojaaminen. Epätietoisuus voi saada lentäjän tekemään vääriä johtopäätöksiä. Työ ei fokusoi harhauttamisen taktiseen kehykseen työn kannalta tarpeellista määrää enempää. Tietosuojasyistä tutkimus ei käsittele käytössä olevien omasuojajärjestelmien operatiivisia ominaisuuksia vaan käsittelee teoriaa niiden taustalla. Tutkimus tehtiin käyttäen taustatutkimukselle enemmän tyypillistä kirjallisuustutkimusta. Jo tutki-muksen alkuvaiheessa oli oletettavaa, että elektronisiin sensoreihin perustuvaa omasuojajärjestelmää pystytään harhauttamaan. Systeemianalysoinnilla pyrittiin löytämään vastauksia tähän olettamukseen. Omasuojajärjestelmästä muodostettiin jo tutkimuksen varhaisessa vaiheessa malli. Tieteellistä kirjallisuutta omasuojajärjestelmistä on olemassa jonkin verran, ja niistä löydettyä tietoa omasuojajärjestelmien ominaisuuksista ja sensoreista yhdistettiin malliin niin, että siitä saatiin mahdollisimman tarkka systeemin kuvaus todellisesta omasuojajärjestelmästä. Analyysin tavoitteena oli löytää niitä kriteereitä, joilla omasuojajärjestelmä saataisiin kohtuullisen tehokkaasti uskomaan harhautusta oikeaksi hälytykseksi. Ohjuksen laukaisusta varoittava sensori perustuu ohjuksen moottorin muodostaman pilven lämpö-säteilyyn. Säteily kuitenkin muuttuu lennon eri vaiheissa, mikä tuottaa haasteita järjestelmälle. Millimetrialueen tutkan käyttö varoittimen sensorina on myös yksi vaihtoehto. Laser-varoittimet toimivat koko sillä taajuusalueella, mitä sotilaskäytössä tulenjohtamiseen ja ohjusten ohjaamiseen käytetään. Tutkavaroittimen tutkimus on vielä kesken. Löydettyjä tuloksia analysoimalla tulen tässä vaiheessa hieman ristiriitaisiin tuloksiin. Lämpösäteilyn käytön suurin haaste on sen eteneminen ilmakehässä. Varoittimen tavoitekaan ei ole toimia kymmentä kilometriä pidemmälle. Yksi mahdollinen ratkaisu on suunnitella ja toteuttaa raketti, jonka tuottaa lämpösäteilyä kuten tietty puolustavan joukon käytössä oleva ohjus. Jos koneessa on kuitenkin myös millimetrialueen tutka tukemassa varoitusjärjestelmää, hankaloituu rakettiharhautus merkittävästi, koska sen pitäisi oletettavasti olla lentokoneen kanssa melko tarkasti kohtaavalla reitillä. Laser-varoitin on ilmeisesti herkin järjestelmistä, koska se voi tietyissä olosuhteissa ja varsinkin matalalla lentokorkeudella aiheuttaa paljon vääriä hälytyksiä ilman tarkoituksellista harhauttamista. Laserin käyttö yhdistettynä raketin laukaisuun saattaisi tuottaa halutun tuloksen. Tutkavaroittimen harhautus onnistuu, jos valelaitteen signaali on uskottavan tarkka.

Kaksifaasijäähdytysjärjestelmään liittyvien pumppujen vertailu ja kehittäminen sarjatuotannon tarpeisiin

Tehoelektroniikalta vaaditaan nykyään parempaa suorituskykyä entistä pienemmässä tilassa. Tämä luo haasteen riittävälle jäähdytykselle. Eräs ratkaisu on käyttää kaksifaasijäähdytystä, jolla aikaansaadaan tehokas lämmönsiirto komponenttien pinnalta. Lämmönsiirtonesteinä voidaan käyttää kylmäaineita tai muita alhaisessa lämpötilassa kiehuvia nesteitä. Tällaisille nesteille on tyypillistä alhainen höyrynpaine sekä matala viskositeetti. Nämä ominaisuudet tuovat haasteita nesteen pumppaukseen. Tässä työssä tarkastellaan R-134A:ta sekä Novec 7000:ta, perehdytään niiden fysikaalisiin ominaisuuksiin sekä materiaaliyhteensopivuuksiin ja näiden tietojen pohjalta etsitään sopivaa pumpputyyppiä kaksifaasijäähdytysjärjestelmään. Tehoelektroniikan jäähdytysjärjestelmän pumpun on oltava edullinen muuhun järjestelmään nähden. Tyypillinen kiertopumppu nestejäähdytysjärjestelmässä on pieni keskipakopumppu. Alhaisen kiehumispisteen vuoksi kavitointiriski kasvaa ja tämä voi vahingoittaa pumppua. Myös matala viskositeetti tuo haasteita vuotoherkkyyden kasvamisen myötä, joten mekaanisilla aksiaalitiivisteillä varustetut pumput eivät ole pitkäikäisiä. Kylmäainejärjestelmiin tarkoitetut pumput ovat arvokkaita, eikä näin ollen sovellu edullisiin jäähdytysjärjestelmiin. Tässä työssä käydään läpi erilaisia pumpputyyppejä, jotka voisivat soveltua pitkäikäiseen pumppaukseen ilman huoltotöitä. Näiden tietojen perusteella kehitetään edullista ja pitkäikäistä pumppua pieniin kaksifaasijäähdytysjärjestelmiin nesteiden fysikaaliset ominaisuudet huomioon ottaen. Kehitetyn pumpun ominaisuuksia ja kustannuksia vertaillaan kaupallisiin ratkaisuihin ottaen huomioon sarjavalmistus. Itse valmistettuna pienelle sisäryntöiselle hammaspyöräpumpulle jää hintaa alle kymmenesosa markkinoilta löytyviin kylmäaineille soveltuviin pumppuun.

Konepajan hitsaustuotannon kehittäminen kattavien laatuvaatimusten mukaiseksi

TIIVISTELMÄ Lappeenrannan teknillinen yliopisto Konetekniikan koulutusohjelma Voitto Kettunen Konepajan hitsaustuotannon kehittäminen kattavien laatuvaatimusten mukaiseksi Diplomityö 2015 167 sivua, 39 kuvaa, 26 taulukkoa ja 3 liitettä Tarkastajat: Professori Jukka Martikainen DI Pertti Kaarre Hakusanat: hitsaus, hitsauksen laatu, konepajan laadunhallinta, kattavat laatuvaatimukset, ISO 9001, ISO 3834, EN 1090 Keywords: welding, quality of welding, engineering workshop quality management, comprehensive quality requirements, ISO 9001, ISO 3834, EN 1090 Hitsaamalla liitetyt teräksiset rakenteet muodostavat ylivoimaisesti suurimman osan konepajatuotannosta. Niihin kuuluu esimerkiksi ajoneuvoja, koneita, laitteita, säiliöitä, siiloja, siltoja, mastoja, piippuja, tukirakenteita ja rakennusten runkoja. Tämän diplomityön tavoitteena on kehittää konepajan laadunhallinta sellaiseksi, että se mahdollistaa kattavien laatuvaatimusten täyttämisen hitsaustuotannossa. Laatuvaatimusten täyttämiseen pyritään käyttämällä hitsaustoimintojen standardia EN ISO 3834-2 sekä kantavien teräsrakenteiden standardeja EN 1090-1 ja EN 1090-2. Teräsrakenteiden suunnittelua ohjaa EN 1993 ja niiden toiminnallisia ominaisuuksia tuotestandardit, kuten terässavupiippu- ja säiliöstandardit. Kantavien teräsrakenteiden suunnittelua ja tuotantoa ohjaa myös seuraamusluokan CC, käyttöluokan SC ja tuotantoluokan PC kautta määräytyvä toteutusluokka EXC. Aikaisempaa enemmän tullaan panostamaan esimerkiksi asiakirjojen sähköiseen hallintaan, raaka-aineiden jäljitettävyyteen tuotteeseen, särmien ja kulmien muotoiluun, pintojen käsittelyyn, hitsien tarkastukseen, hitsaushenkilöstön pätevyyteen ja hitsaustuotannon tehokkuuteen. Saarijärven Säiliövalmiste Oy:n hitsauksen laadunhallinta sertifioitiin standardin ISO 3834-2 mukaan ja kantavien teräsrakenteiden FPC-järjestelmä standardisarjaa EN 1090 noudattaen. Samalla tehtiin päivitys laadunhallintajärjestelmään ISO 9001. Toteutus, joka tehtiin sovitussa aikataulussa, haastaa jokaisen toimijan konepajassa toiminnan, tuotannon ja tuotteiden laadun kehittämiseen uusia käytänteitä ja menetelmiä soveltaen. Kehitystoimien tuloksena toiminta on selkeämpää, ennakoitavampaa ja hallitumpaa, mikä lisää yrityksen toiminnan tuottavuutta ja kannattavuutta. Sertifioidut laatujärjestelmät ovat myötävaikuttaneet tilausten lisääntymiseen yrityksen kaikkien tuotteiden osalta.

Biological evaluation of recombinant human erythropoietin in pharmaceutical products

The potencies of mammalian cell-derived recombinant human erythropoietin pharmaceutical preparations, from a total of five manufacturers, were assessed by in vivo bioassay using standardized protocols. Eight-week-old normocythemic mice received a single subcutaneous injection followed by blood sampling 96 h later or multiple daily injections with blood sampling 24 h after the last injection. Reticulocyte counting by microscopic examination was employed as the end-point using the brilliant cresyl blue or selective hemolysis methods, together with automated flow cytometry. Different injection schedules were investigated and dose-response curves for the European Pharmacopoeia Biological Reference Preparation of erythropoietin were compared. Manual and automated methods of reticulocyte counting were correlated with respect to assay validity and precision. Using 8 mice per treatment group, intra-assay precision determined for all of the assays in the study showed coefficients of variation of 12.1-28.4% for the brilliant cresyl blue method, 14.1-30.8% for the selective hemolysis method and 8.5-19.7% for the flow cytometry method. Applying the single injection protocol, a combination of at least two independent assays was required to achieve the precision potency and confidence limits indicated by the manufacturers, while the multiple daily injection protocol yielded the same acceptable results within a single assay. Although the latter protocol using flow cytometry for reticulocyte counting gave more precise and reproducible results (intra-assay coefficients of variation: 5.9-14.2%), the well-characterized manual methods provide equally valid alternatives for the quality control of recombinant human erythropoietin therapeutic products.
