[pt] Uma das estratégias mais populares para publicar dados estruturados na Web é expor bases de dados relacionais (BDR) em formato RDF. Esse processo é chamado BDR-para-RDF ou triplificação. Além disto, princípios de Linked Data oferecem vários guias para dar suporte a este processo. Existem duas principais abordagens para mapear bases de dados relacionais para RDF: (1) a abordagem de mapeamento direto, onde o esquema das bases de dados é diretamente mapeado para um esquema RDF, e (2) a abordagem de mapeamento customizado, onde o esquema RDF pode ser significativamente diferente do esquema original da base de dados relacional. Em ambas abordagens, existem vários desafios relacionados tanto com a publicação quanto com o uso de dados em RDF originados de bases de dados relacionais. Esta tese propõe a coleta de design rationale como uma valiosa fonte de informação para minimizar os desafios do processo de triplificação. Essencialmente, a coleta de design rationale melhora a consciência sobre as ações feitas no mapeamento da base de dados relacional para um conjunto de dados no formato RDF. As principais contribuições da tese são: (1) um modelo de design rationale (DR) adequado para o processo de BDR-para- RDF, independente da abordagem utilizada (direta ou customizada); (2) a integração de um modelo de DR para um processo que segue a abordagem direta de BDR-para-RDF e para um processo que segue a abordagem customizada usando a linguagem R2RML; (3) o uso do DR coletado para melhorar recomendações de reuso de vocabulários existentes através de algoritmos de Ontology Matching. / [en] One of the most popular strategies to publish structured data on the Web is to expose relational databases (RDB) in the RDF format. This process is called in RDB-to-RDF or triplification. Furthermore, the Linked Data principles offer useful guidelines for this process. Broadly stated, there are two main approaches to map relational databases into RDF: (1) the direct mapping approach, where the database schema is directly mapped to an RDF schema; and (2) the customized mapping approach, where the RDF schema may significantly differ from the original database schema. In both approaches, there are challenges related to the publication and to the consumption of the published data. This thesis proposes the capture of design rationale as a valuable source of information to minimize the challenges in RDB-to-RDF processes. Essentially, the capture of design rationale increases the awareness about the actions taken over the relational database to map it as an RDF dataset. The main contributions of this thesis are: (1) a design rationale (DR) model adequate to RDB-to-RDF processes, independently of the approach (direct or customized) followed; (2) the integration of a DR model in an RDB-to-RDF direct mapping process and in an RDB-to-RDF customized mapping process using the R2RML language; (3) the use of the DR captured to improve the recommendations for vocabularies to reuse.

[pt] Valores de usuário são um fator importante no design de software, mas nem sempre são considerados de forma explícita no processo de design. Ao tomar decisões de design, valores de usuários podem se perder junto aos viéses dos designers relacionados a seus próprios valores. Para evitar esse problema, este trabalho estuda a integração de valores de usuários com técnicas de design rationale, especificamente Questões, Opções e Critérios (QOC), e como essa integração é refletida em um artefato de design resultante (um diagrama de interação usando MoLIC). Conduzimos dois estudos separados com estudantes de Ciência da Computação no Rio de Janeiro. No primeiro estudo, vimos que valores de usuários podem ser integrados com design rationale usando notações informais, como circulando ou sublinhando as opções ou critérios associados a valores de usuários. As decisões tomadas com o método QOC usando valores de usuário resultaram em impactos relevantes nos diagramas MoLIC. Participantes que realizaram as atividades para usuários com valores bem definidos tiveram resultados mais ricos do que aqueles com usuários mais genéricos. No segundo estudo, vimos que designers conseguem reconhecer quando valores de usuários são incorporados em artefatos de design. Esses resultados são estimulantes para continuar a pesquisar valores de usuários, com possibilidades de desenvolver novos métodos ou de atualizar técnicas e notações existentes, como QOC ou MoLIC, para dar suporte a valores de usuários. / [en] User values are a significant part of designing software, but are not always considered explicitly in the design process. When making design decisions, user values can get lost among the designers own biases regarding their values. To avoid this pitfall, this work studies the integration of user values with design rationale techniques, namely Questions, Options, and Criteria (QOC), and how this integration reflects on a resulting design artifact (in particular, an interaction diagram using MoLIC). We performed two separate studies with Computer Science students in Rio de Janeiro. In the first study, we found that user values can be integrated into design rationale using informal notations, such as circling or underlining the options or criteria related to user values. The decisions made with the QOC method using user values did result in relevant impacts on MoLIC diagrams. Participants who performed activities for users with strong values had richer results than those for more generic users. In a second study, we found that designers can recognize when user values are embedded into design artifacts. These results are encouraging to continue research regarding user values, with possibilities of developing new methods or updating existing techniques and notations such as QOC or MoLIC to explicitly support user values.

This work examines sustainable functions for another workwear. It argues fora culture shift within many fields: private, politically, global, local as well as infashion. The background is earth and human beings current situation whichneeds to be changed in order to create a sustainable living. This is understoodin the ecological, sociocultural and economical sustainable model and contextualixedfor agricultural workwear.The issue of construction methods in workwear is examined and understoodin relationship to the non-rationale and aesthetical function; the need to workand the need to dwell.New ideas of rationale function workwear is proposed which argues for theneed of a greater look upon sustainability and non-rationale ideas within thefield of current workwear.This includes:1.

Ce travail de thèse s'intéresse à l'étude des processus de conception de produits dans le cadre de projets d'innovation. L'approche proposée se focalise sur les connaissances associées aux processus de décision, identifiées comme critiques dans ces projets.<br />Les contributions de ce travail de recherche sont centrées sur la compréhension des mécanismes de décision et le support à leur bon déroulement. En premier lieu, un modèle de processus de décision, appelé INDIGO est proposé. Il a pour objectif de représenter l'ensemble des informations associées aux processus de décision, regroupées en un modèle unique, multi-vues. Il s'agit de la vue structure de la décision (les éléments d'information de l'espace de décision), de la vue processus de décision (les activités de décision), de la vue organisation de la décision (les acteurs impliqués dans la décision). Un Système de Gestion des Connaissances, appelé MEYDIAM est ensuite proposé. Il est fondé sur la proposition d'une nouvelle approche de Gestion des Connaissances. Il permet la création et la réutilisation de connaissances liées à la décision par l'utilisation d'informations structurées par le modèle INDIGO. MEYDIAM est principalement constitué dune mémoire de projet. Cet outil, au moyen d'interfaces appelées objets de connaissances, permet de capturer, au fil de l'eau les informations associées aux processus de décision et de les<br />réutiliser. Les contributions ont été validées via une maquette informatique testée dans le cadre des projets d'innovation du groupe PSA PEUGEOT CITROËN.

This thesis work is based on the previous researches in design automation at Sandvik Coromant. The concept of product family description (PFD) has been introduced to the company to improve documentation of knowledge in engineering design process. Current documentation at the company for engineering design covers mostly the design definition part of the knowledge. PFD is constituted by design definition and completed by design rationale. This kind of documentation improves reusing, revising and expanding the knowledge at the company. On the other side, PFD is an input for design programming and a good engineering design description for a product provides more efficiency in design programming. The project is started by a survey for several principles and applications for knowledge modelling. Product variant master (PVM) and Semantic MediaWiki are selected by the results of the survey. To show the concept of PVM, modelling of a test product is done in product model manager (PMM) software. The main part of the project is setting up product family description (PFD) by capturing design rationale for the test product, implementing in Semantic MediaWiki. Since the design rationale is not documented, it was recorded during several meetings with the designer of the test product. The description is completed by including the argumentations about the rules, figures, dimensions and etc. Also in the project has been tried to improve and revise the description to make it more simple and efficient. Another objective of the project is to show Semantic MediaWiki as a candidate application for modelling knowledge at the company. In this step the applicability and functionality of both PFD and Semantic MediaWiki is seen. In the next stage the project findings and company documentation are evaluated. In this step has been tried to show the pros and cons of the project. The emphasis of the evaluation is on PFD and the alternative application. In the end a conclusion of the whole methods and findings of the project comes with discussion with people who were involved in this work.

The Grade 1-9 curriculum policy has changed the traditional curriculum rationale and curriculum design. The large scale and profound influence of this change can be considered a revolutionary transformation during the educational process in Taiwan. The policy implementation has particularly focused on the elementary school and junior high school teachers, which involves not only the change in teachers¡¦ instructional patterns, but also teachers¡¦ professional roles as well as the transformation of their values. ¡@¡@Ideas of the Grade 1-9 curriculum policy have conveyed certain concepts. However, when the policy is implemented, a lot of details are involved, such as instructional plan, instructional method, action research, which require teachers¡¦ abilities for preparation, accompanying measures related to administration, or even the general public¡¦s and parent¡¦s questions about and support of the policy. All these have caused a lot of difficulties during the process of policy administration. Among them, the key point is whether the elementary school and junior high school teachers can identify themselves with the ideas of the curriculum reform, and dedicate themselves to implement this policy goal, which is closely tied to the substantial outcomes of this policy. Based on the context of this problem, it is worthy of a study on understanding this problem, and even resolving the problem. ¡@¡@An educational philosophy works as a basis to form a policy, and does not happen independently in the system of an educational structure. In turn, it is a response to the social context at that time, and is related to the social value system then. When the policies and ideas are implemented, a critical examination of social habits should not be ignored. In order to emphasize the policy analysis of curriculum reform implementation, if the society is considered the conceptual background of policy analysis, the policy formation can be more correctly and comprehensively understood, and can work as a basis to explain the problems due to the policy administration. ¡@¡@On these grounds, this study is based on the social concepts of the Grade 1-9 curriculum policy, and attempts to investigate the correlation between grassroots teachers¡¦ social values and the reform of the Grade 1-9 curriculum policy. The purpose is to explain the relationship between different teachers¡¦ social values and the policy of the curriculum reform, to understand cognitive differences as well as to test and verify the applicability of the methods to reduce the cognitive differences and resolve the cognitive conflicts. ¡@¡@In terms of the research method, the researcher first has referred to Inglehart¡¦s hierarchy of needs (1990:25) to measure the priority of the value index in the social values, and categories the teachers in the study into two different social value groups: materialism and post-materialism. The quasi-experimental method of the Social Judgment Theory (SJT) is applied to judge and analyze the study. The concept of ¡§V.C.S. Strategic Triangle, ¡¨ is applied to define the three indices, value-capacity-support (V.C.S.), in the Grade 1-9 curriculum policy implementation. The function and application of the lens model in the SJT, thus, are verified. It is hoped to test, verify and explain the different cognitive judgments on the beneficial results of the curriculum reform and V.C.S. policy implementation made by the teachers with different social values (criteria, cues, function form, weights, judgment policy and cognitive feedback). ¡@¡@Among the above-mentioned methods, the cognitive feedback model is especially applied to present the subjects¡¦ internal cognitive judgment on policy reference variables, for the purpose of helping the subjects to judge their level of cognitive change after they directly understand and compare their interpersonal learning with others. The findings are as follows: 1. Teachers with different social backgrounds and conditions have different value orientations. 2. Based on the SJT method, two groups with different social values have different cognitive levels of the curriculum policy reform¡¦s beneficial results. (1) The criteria of the curriculum policy reform¡¦s beneficial results among the subjects with different value orientations are very inconsistent, which indicates the cognitive differences between these two groups. (2) Groups with different social values cause different function form models and weights of the three policy reference variables: ¡§V¡¨ ¡§C¡¨ and ¡§S¡¨. Materialists tend to identify themselves with the variable, ¡§S¡¨ while the post-materialists with the other two variables, ¡§V¡¨ and ¡§C¡¨. (3) The three policy reference variables; namely, ¡§V¡¨ ¡§C¡¨ and ¡§S¡¨ among groups with different social values show lower similarity in the judgment policy. 3. After experiencing the interpersonal learning of cognitive feedback, groups with difference social values will make cognitive changes, which result in the narrowed cognitive differences between these two groups. (1) After the cognitive feedback, the cognitive consistency with the subjects will increase. (2) After the cognitive feedback, the actual value and estimated value of the test results among groups with different social values will have higher agreement. (3) After the cognitive feedback, the three function form, and weights, namely, ¡§V¡¨ ¡§C¡¨ and ¡§S¡¨ among groups with different social values have been adjusted toward the cognitive orientation different from theirs (4) After the cognitive feedback, the three cues, namely, ¡§V¡¨ ¡§C¡¨ and ¡§S¡¨ among groups with different social values show higher similarity in the judgment policy. 4. The results of the questionnaire found that groups with different social values and social attributes (such as social conditions during the growing process, family¡¦s social-economic status, age and educational background) have different levels of identification with the three indices, namely, ¡§V¡¨ ¡§C¡¨ and ¡§S¡¨ Materialists tend to identify themselves with the variable, ¡§support,¡¨ while post-materialists with the other two variables, ¡§V¡¨ and ¡§C¡¨. The research results are identical with the research results of the SJT.
