Development of Collaborative Product Structure Management

The purpose of this thesis is to develop an environment or network that enables effective collaborative product structure management among stakeholders in each unit, throughout the entire product lifecycle and product data management. This thesis uses framework models as an approach to the problem. Framework model methods for development of collaborative product structure management are proposed in this study, there are three unique models depicted to support collaborative product structure management: organization model, process model and product model. In the organization model, the formation of product data management system (eDSTAT) key user network is specified. In the process model, development is based on the case company’s product development matrix. In the product model framework, product model management, product knowledge management and design knowledge management are defined as development tools and collaboration is based on web-based product structure management. Collaborative management is executed using all these approaches. A case study from an actual project at the case company is presented as an implementation; this is to verify the models’ applicability. A computer assisted design tool and the web-based product structure manager, have been used as tools of this collaboration with the support of the key user. The current PDM system, eDSTAT, is used as a piloting case for key user role. The result of this development is that the role of key user as a collaboration channel is defined and established. The key user is able to provide one on one support for the elevator projects. Also the management activities are improved through the application of process workflow by following criteria for each project milestone. The development shows effectiveness of product structure management in product lifecycle, improved production process by eliminating barriers (e.g. improvement of two-way communication) during design phase and production phase. The key user role is applicable on a global scale in the company.

Use of semi-seletive media for detection of Sclerotinia sclerotiorum on bean and soybean seeds

This work was aimed at evaluating the possibility of using bromophenol blue as an indicator for detecting the presence of Sclerotinia sclerotiorum in the seeds of dry-beans (Phaseolus vulgaris) and soybean (Glycine max), through incubation of the seeds on an agar medium and "blotter" substrates. The seeds were artificially inoculated with four S. sclerotiorum isolates, plated on the agar medium, named Neon, and on modified Neon agar media all incubated at 14 and 20 ºC for seven days in the dark. Half of the seeds inoculated were surface desinfested prior to plating on the medium. The seeds showing change of colour in the medium, from blue to light yellow, as well as formation of typical mycelium and sclerotia in some cases, were considered to be infected or contaminated by S. sclerotiorum. The two incubation temperatures compared did not show significant (P<0.05) differences in detection level for most of the isolates tested on the different media. According to results obtained in this study, the Neon agar medium with incubation at 14 or 20 ºC has proved to be a reliable and quick method for the detection of S. sclerotiorum mycelium in naturally infected seeds of bean and soybean.

Distribuição espacial da meleira do mamoeiro em zonas de trópico úmido e trópico semi-árido

O vírus da meleira, transmitido por Bemisia tabaci, é um dos maiores problemas da cultura do mamoeiro (Carica papaya), sendo responsável por perdas de até 100% na produção. Com o objetivo de compreender melhor sua epidemiologia e gerar subsídios para estudos da influência de fatores culturais e bioecológicos na dinâmica da doença, avaliou-se a distribuição espacial de plantas afetadas pela meleira em zonas de Trópico Úmido e Trópico Semi-árido, em 15 plantios comerciais em Eunápolis-BA e Petrolina-PE, entre jan. 2000 e mar. 2001. As áreas foram mapeadas anotando-se a posição de cada planta e a presença ou ausência de sintomas. Foram consideradas doentes aquelas que apresentavam frutos com exsudação espontânea do látex, látex muito fluido, frutos borrados e/ou folhas do ápice com o bordo necrosado. Pelas análises de seqüências ordinárias, índice de dispersão, áreas isópatas e ajuste dos logaritmos das variâncias binomial e de acordo com a lei de Taylor, observaram-se maior agregação nas linhas de plantio que entre linhas e uma agregação de mediana a forte em sub-áreas (1,4 < ID < 3,1). Na maioria dos lotes, as áreas de maior incidência concentraram-se nas bordas dos talhões, o que indica que a migração de vetores assume um papel importante na disseminação da doença. Em alguns casos foi possível detectar a presença de focos isolados no interior dos lotes, o que sugere a formação de colônias dos vetores e transmissão planta a planta a partir de inóculo secundário. Não foram observadas diferenças significativas na distribuição espacial de plantas doentes entre as áreas das duas regiões.

A Semi-Selective agar medium to detect the presence of Xanthomonas axonopodis pv. malvacearum in naturally infected cotton seed

A semi-selective agar medium was developed for detection of Xanthomonas axonopodis pv. malvacearum (Xam) in cotton (Gossypium hirsutum) seed. The basic medium was peptone-sucrose-agar (PSA). Criteria for the semi-selective medium were the typical colony characters of Xam and its pathogenicity on cotton. Several systemic fungicides and antibiotics in different concentrations were tested alone or in combination with others. The final composition of the semi-selective agar medium was established after several attempts in order to inhibit most of the fungal and bacterial saprophytes and favour the development of Xam. It contained PSA + cyclohexamide, cephalexin, pencycuron, triadimenol and tolylfluanid. The bacteria were recovered from naturally infected seeds by the direct plating of 2,000 surface disinfected seeds on the semi-selective medium. The recovery of the pathogen from naturally infected leaf tissues and in dilution plating, on semi-selective medium and on nutrient agar, were comparable. Among the three detection methods tested, the semi-selective medium was found to be the most reliable and quantifiable. Degree of severity of angular leaf spot in the field was not always correlated with the level of infection in the seed. This is the first report of a semi-selective agar medium to detect the presence of Xam in naturally infected cotton seed.

O meio de cultura semi-seletivo XCP1 foi o mais eficiente na quantificação e detecção de Xap em extratos de sementes inteiras de feijão. Os extratos de sementes contaminadas, inoculados nas folhas primárias de feijoeiro produziram sintomas do crestamento bacteriano comum.

Tutkimus- ja kehitysvaiheen toteuttaminen teknologisessa innovaatioprosessissa

Through the ages technological changes have created new challenges and possibilities to develop products, services, processes or organizations. Management of the technology concerns all of those activities from technical invention to commercial application. Management of the technologic innovation process is the more challenging the more technology is involved in a process. Researches of the technological innovations are seldom concern the implementation of early phases and especially in product manufacturing company. Still there are research and development activities. Therefore the purpose of this research is to develop the pattern for implementation of research and development phases in technological innovation process. This study focuses the main elements of the technological innovation management and main obstacles and drivers. This study also focuses decision making and the other influencing elements of the decision making. The research design of this explorative research applies a qualitative research strategy where a case study method is utilized to collect and analyze the data. The study consisted of a single case to utilize of technological ideas and possibilities. The selected case company was the product manufacturing company which didn’t have own technological research and development organization. The case was a process which was analyzed from two different perspectives. The main unit of analysis was the whole process. The data collecting method of this study included semi-structured and open interviews, participant-observations and experimental tests. Analyzing the case data relies on the theoretical propositions of the framework based on the previous research. Based on this research the key elements of the research and development phases in technological innovation process were technical expertise and preliminary investigation.

The findings of this study gave further insight implementation of the technological innovation in the product manufacturing company. The research was based a single case which means the results cannot be generalized to different companies or industry fields. Therefore the results generalizing require further research with multiple researchers.

Tutkimus- ja kehitysvaiheen toteuttaminen teknologisessa innovaatioprosessissa

Teknologiset muutokset ovat kautta aikojen luoneet uusia haasteita ja mahdollisuuksia tuotteiden, palveluiden, prosessien tai organisaatioiden kehittämiseen. Teknologian johtaminen tarkoittaa kaikki niitä toimia, joiden avulla teknologisesta keksinnöstä saadaan kaupallinen sovellus. Teknologisen innovaatioprosessin johtaminen on, sitä haasteellisempaa, mitä enemmän siinä on mukana teknologiaa. Harvoin teknologisten innovaatioiden tutkimukset ovat kohdistuneet prosessin varhaisen vaiheen toteutukseen ja erityisesti tuotannolliseen toimintaan keskittyvissä yrityksissä, vaikka kaikissa tuotteita valmistavissa teollisuuksissa tapahtuu tutkimus- ja kehitystyötä. Siksi tämän tutkimuksen tavoitteena on kehittää toimintamalli teknologisen innovaatioprosessin tutkimus- ja kehitysvaiheen toteuttamiselle. Tutkimus keskittyy teknologisen innovaatioprosessin tärkeimpiin elementteihin johtamisen ja prosessin kannalta sekä sen estäviin ja edistäviin tekijöihin. Tutkimuksessa tarkastellaan myös päätöksentekoa ja siihen vaikuttavia tekijöitä. Tutkimus oli kartoittava ja sillä oli laadullinen tutkimusstrategia. Tarkempi tutkimusmenetelmä kerätä ja analysoida tutkimustietoa oli tapaustutkimus. Tämä tutkimus perustui yhteen tapaukseen teknologisten ideoiden ja mahdollisuuksien hyödyntämisestä. Valittu tapausyritys oli tuotteita valmistava yritys, jolla ei ollut varsinaista tutkimus- ja kehitysorganisaatiota teknologian kehittämistä varten. Itse tapaus oli prosessi, jota analysoitiin kahdesta eri näkökulmasta, mutta primääri analysointiyksikkö oli koko prosessi. Aineiston hankintamenetelmät olivat puolistrukturoidut ja avoimet haastattelut, osallistuva havainnointi ja kokeelliset tutkimukset. Aineiston analysointi perustui aikaisemmin tutkimuksen yhteydessä rakennettuun teoreettiseen viitekehykseen. Teknologisen innovaatioprosessin tutkimus- ja kehitysvaiheen tärkeimmät elementit tutkimuksen mukaan olivat oman teknologian asiantuntemus ja esitutkimusvaihe. Tekijät, jotka tutkimuksen mukaan estivät ja edistivät T&K -vaiheen onnistumista, olivat koko prosessin ja resurssien johtaminen sekä tietoisuus prosessin tavoitteista ja prosessin aikainen oppiminen. Tutkimuksessa löydettiin myös päätöksentekoon liittyvä ominaisuus optimoida siihen käytettävää aikaa. Tutkimuksen tulokset lisäsivät näkemystä teknologisten innovaatioiden toteuttamisesta tuotteita valmistavassa yrityksessä. Tutkimus perustui yhteen tapaukseen, minkä vuoksi tulokset eivät ole yleistettävissä muihin yrityksiin tai toimialoihin. Tulosten yleistämistä varten tutkimuksia tulisi suorittaa lisää ja käyttää useita tutkijoita.

Outsourcing process in pharmaceutical product development

The aim of this study was to create an outsourcing process for pharmaceutical product development. This study focuses on two main questions. The first question is “What is the outsourcing process model?” In the second phase key success factors of the outsourcing process are identified. As a result of the literature reviews, a general outsourcing process was created. Transaction cost economics and resource based view were used to derived a theoretical framework to the process by combining the existing processes presented in the literature. The model of process is considered used to the outsourcing broadly. The general outsourcing process was then developed further with the key factors that affect the success of pharmaceutical product development and the interviews of pharmaceutical outsourcing experts. The result of the research was the process consists of seven phases with key activities and expected outputs for each of the phases. In addition, the strategic decision-making framework for outsourcing decision in pharmaceutical product development is giving as well as the tools for selecting supplier and preparing structured contract. This study also gives some recommendations for managing the outsourcing process.

Network Structures and Modularity among Biofuel Heating System Manufacturers

The aim of this thesis was to study network structures and modularity among biofuel heating system manufacturers in the Finnish bioenergy sector by utilizing the perspectives of numerous Finnish bioenergy specialists. The study is qualitative due to the fact that the research material was gathered with semi-structured theme interviews during May and June 2010. The research methodology used in the thesis combines conceptual and action-oriented approach. Networks, value nets, and modularity were studied from different perspectives. Three network and platform strategies were discovered and a general network structure was formed. Moreover, benefits and disadvantages of networks and modularity among biofuel heating system manufacturers were illustrated. The analysis provides a comprehensive perception of the industry. The results of the research were constructed by implementing existing theories into practice. Also future recommendations for the biofuel heating system manufacturers were given. The results can be considered to be beneficial because the number of previous studies about the subject is relatively small. The reliability of the study is eminent because the number of the interviews was inclusive.

Product costing model for laser welded hollow core steel panels

The aim of the study was to create an easily upgradable product costing model for laser welded hollow core steel panels to help in pricing decisions. The theory section includes a literature review to identify traditional and modern cost accounting methodologies, which are used by manufacturing companies. The theory section also presents the basics of steel panel structures and their manufacturing methods and manufacturing costs based on previous research. Activity-Based costing turned out to be the most appropriate methodology for the costing model because of wide product variations. Activity analysis and the determination of cost drivers based on observations and interviews were the key steps in the creation of the model. The created model was used to test how panel parameters affect the costs caused by the main manufacturing stages and materials. By comparing cost structures, it was possible to find the panel types that are the most economic and uneconomic to manufacture. A sensitivity analysis proved that the model gives sufficiently reliable cost information to support pricing decisions. More reliable cost information could be achieved by determining the cost drivers more accurately. Alternative methods for manufacturing the cores were compared with the model. The comparison proved that roll forming can be more advantageous and flexible than press brake bending. However, more extensive research showed that roll forming is possible only when the cores are designed to be manufactured by roll forming. Due to that fact, when new panels are designed consideration should be given to the possibility of using roll forming.

Examining the Role of Rebranding in Perceived Image of a Product Line

The main objective for this study was to explore certain organization’s product line rebranding process and its impact on product line’s perceived image. The case company is a global paper, packaging and forest products company, business segment paper board. The audience explored is one of the company’s major customers, merchant in Germany. The research was performed as a descriptive case study with a purpose to provide longitudinal insight into the product line image and its eventual alteration as a result of the case company’s rebranding process. Mainly qualitative methods were used for conducting the research. The data for the empirical part was collected with a web-based survey at two different points of time; before the rebranded products entered the market and after they had been available approximately six months. The results of this study reveal that the case company has performed well in its attempt to improve product line’s brand image through rebranding. It was found that between the two brand image measurements the product brand image seems to have improved in all of the areas which according to theoretical framework of this study contribute to formation of brand image; brand associations, marketing communications and interpersonal relationships, not forgetting the original platform that initiated the change; technical quality modifications. In other words it may be concluded that as technical quality was brought to a new level, also assessments about the brand image improved respectively.

Meio de cultura semi-seletivo para detecção de Curtobacterium flaccumfaciens pv. flaccumfaciens em solo e sementes de feijoeiro

A murcha-de-curtobacterium, causada pela bactéria Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), é um importante problema para o cultivo de feijão (Phaseolus vulgaris L.) na região Centro-Sul do Brasil. A principal forma de disseminação da bactéria é por sementes contaminadas. Embora a ocorrência desta doença seja relativamente recente no Brasil, Cff tem sido disseminado rapidamente nas regiões produtoras de feijão do país. Este trabalho teve como objetivo ajustar o meio de cultura CNS (Corynebacterium Nebraskense Selective Medium) para recuperação e detecção de Cff em solo e sementes de feijoeiro. Suspensões provenientes da lavagem de amostras de solo e sementes contaminadas pela bactéria foram plaqueadas no meio de cultura CNS - modificado. Os ajustes realizados no meio de cultura possibilitaram a recuperação eficiente de Cff presente em solo e sementes contaminadas. As modificações estabelecidas para o meio CNS foram a redução da concentração de sulfato de polimixina para 16 mg/l, exclusão do componente ciclohexamida e substituição do fungicida Daconil 2787-F (530 mg/ml de chlorothalonil) pelo Dacostar 500 (500 mg/ml de chlorothalonil).

Meio semi-seletivo para detectar Xanthomonas axonopodis pv. phaseoli em sementes de feijoeiro e sua erradicação através do tratamento de sementes com o fungicida tolylfluanid

Estudou-se a eficiência do meio semi-seletivo desenvolvido para Xanthomonas axonopodis pv. malvacearum (Xam) do algodoeiro, com algumas modificações, na detecção de Xanthomonas axonopodis pv. phaseoli (Xap) em sementes de feijoeiro, bem como a eficiência do fungicida tolylfluanid na erradicação de Xap através do tratamento de sementes. Foram utilizadas sementes naturalmente infectadas por Xap, procedentes de diferentes municípios do Estado do Paraná. Houve o desenvolvimento de colônias bacterianas ao redor das sementes infectadas sob meio semi-seletivo entre seis e 12 dias de incubação. A freqüência de recuperação de colônias da bactéria em relação ao meio Agar nutriente (AN) variou entre 30 a 112%. O crescimento de Xap foi inibido a concentrações entre 54 a 1500 ppm do fungicida tolylfluanid. A bactéria foi recuperada das sementes não tratadas em meio semi-seletivo, mas não das sementes tratadas em solução do fungicida tolylfluanid (1,20g/L água). Em casa de vegetação, das 400 sementes tratadas com tolylfluanid não foi produzida nenhuma planta com sintomas da doença até 30 dias após a semeadura, enquanto que 9,75% das sementes não tratadas apresentaram sintomas de Xap. Em um outro experimento, das 1200 sementes não tratadas um total de 7,08% e 11,67% das plantas mostraram-se com sintomas da doença, enquanto que das sementes tratadas 0,5% e 2,4% apresentaram sintomas, 26 e 46 dias após a semeadura, respectivamente.

Semi-selective medium for Fusarium graminearum detection in seed samples

Fungi of the genus Fusarium cause a variety of difficult to control diseases in different crops, including winter cereals and maize. Among the species of this genus Fusarium graminearum deserves attention. The aim of this work was to develop a semi-selective medium to study this fungus. In several experiments, substrates for fungal growth were tested, including fungicides and antibiotics such as iprodiona, nystatin and triadimenol, and the antibacterial agents streptomycin and neomycin sulfate. Five seed samples of wheat, barley, oat, black beans and soybeans for F. graminearum detection by using the media Nash and Snyder agar (NSA), Segalin & Reis agar (SRA) and one-quarter dextrose agar (1/4PDA; potato 50g; dextrose 5g and agar 20g), either unsupplemented or supplemented with various concentrations of the antimicrobial agents cited above. The selected components and concentrations (g.L-1) of the proposed medium, Segalin & Reis agar (SRA-FG), were: iprodiona 0.05; nystatin 0,025; triadimenol 0.015; neomycin sulfate 0.05; and streptomycin sulfate, 0.3 added of ¼ potato sucrose agar. In the isolation from seeds of cited plant species, the sensitivity of this medium was similar to that of NSA but with de advantage of maintaining the colony morphological aspects similar to those observed in potato-dextrose-agar medium.
