Towards a lightweight adaptative multicomponential affective recognition system

As part of the Affective Computing research field, the development of automatic affective recognition systems can enhance human-computer interactions by allowing the creation of interfaces that react to the user's emotional state. To that end, this Master Thesis brings affect recognition to nowadays most used human computer interface, mobile devices, by developing a facial expression recognition system able to perform detection under the difficult conditions of viewing angle and illumination that entails the interaction with a mobile device. Moreover, this Master Thesis proposes to combine emotional features detected from expression with contextual information of the current situation, to infer a complex and extensive emotional state of the user. Thus, a cognitive computational model of emotion is defined that provides a multicomponential affective state of the user through the integration of the detected emotional features into appraisal processes. In order to account for individual differences in the emotional experience, these processes can be adapted to the culture and personality of the user.

Interfaces e organização da pesquisa no Brasil: da Química à Nanotecnologia

Nanotechnology can be viewed as a powerful tool, capable of shaping the chemistry of atoms and molecules, converting them into exciting nanosized and nanostructured materials, devices and machines. However, in pursuing this task, an exceptional ability is required to deal with complex inter- and multidisciplinary approaches, as imposed by the nanoscale. A new research organization framework, capable of promoting cooperative interactions in many complementary areas, including the industries, is demanded. In this sense, an interesting example are the nanotechnology networks and millenium institutes recently created in Brazil. The highlights and weakness of such cooperative research networks are discussed, in addition to relevant nanotechnology themes focusing on the special needs and resources from the developing nations.

Interfaces com a indústria

Brazilian chemical industries face several problems regarding Research, Development and Innovation (RDI). The present paper shows that simple cooperation between chemical industries and university laboratories can be a way to overcome some of the present difficulties. The work carried out at LABOCAT has several industrial interfaces. It involves, among other areas of RDI, the development of anti-HIV-protease (and other virus-related-protease) drugs, the establishment of new (industrial) chemical processes and the implementation of industrial (biodiesel and related) plants. A model based on the present so called RHAE programme is proposed in which, parallel to the fellowship awards of this programme, financing participation of Brazilian Agencies would cover process development.

Palveluväylän hyödyntäminen palvelukeskeisessä arkkitehtuurissa

Palvelukeskeinen arkkitehtuuri on uusi tapa rakentaa tietojärjestelmiä. Se perustuu siihen, että logiikasta koostetaan yleiskäyttöisiä palveluita, joita tarjotaan muiden järjestelmän osien käyttöön. Tällöin samoja asioita ei tarvitse toteuttaa moneen kertaan ja järjestelmää voidaan hyödyntää tehokkaasti ja monipuolisesti. Näiden palveluiden hallinnassa voidaan hyödyntää palveluväyliä, eli ESB -tuotteita. Palveluväylät sisältävät erilaisia mekanismeja, joiden avulla palveluihin liittyvää viestiliikennettä voidaan reitittää, muokata ja valvoa eri tavoin. Nykyisissä palvelukeskeisissä toteutuksissa käytetään usein XML -kieleen pohjautuvia Web Service -määrityksiä. Ne tarjoavat ympäristöriippumattoman pohjan, joka täyttää suoraan useita palvelukeskeisen arkkitehtuurin vaatimuksia. Määritysten ympärille on myös paljon valmiita laajennuksia, joiden avulla palveluihin voidaan liittää lisätoiminnallisuutta. Lahden kaupunki lähti Fenix -projektin yhteydessä kehittämään uutta kuntien käyttöön soveltuvaa järjestelmää, joka hyödyntää palvelukeskeisen arkkitehtuurin periaatteita. Järjestelmä jaettiin selkeisiin kerroksiin siten, että käyttöliittymä erotettiin palvelulogiikoista palveluväylän avulla. Tällöin järjestelmä saatiin jaettua loogisiin kokonaisuuksiin, joilla on selkeä rooli. Taustapalvelut hoitavat käsitteiden hallinnan, sekä niihin liittyvät liiketoimintasäännöt. Käyttöliittymäkerros hoitaa tiedon esittämisen ja tarjoaa graafisen, selainpohjaisen käyttöliittymän palveluihin. Palveluväylä hoitaa liikenteen reitittämisen, sekä huolehtii palveluihin liittyvistä käyttöoikeuksista ja tilastoinnista. Lopputuloksena on loputtomiin laajennettavissa oleva järjestelmä, jonka päälle voidaan kehittää erilaisia sähköisiä palveluita kunnan ja sen asukkaiden välille.

Evaluating End-User Training Effectiveness in ERP System Implementation

Today’s business world demands more and more internal and external integration and transparency among companies at all fields. Integrated ERP (enterprise resource planning) systems offer a possibility to improve business practices and procedures by providing a unified view on the business including all functions and departments. Due to the obvious benefits, the popularity of integrated ERP systems keeps growing. The implementation of ERP systems has however proven risky. The implementation projects tend to be long, extensive, and costly – and often they end up in a failure. Due to the significant task and role changes ERP implementation brings to almost everybody in the company, training has been identified as one of the most critical success factors of an ERP implementation. To ensure that the training is conducted in the most effective and successful manner, the training outcomes should be evaluated. So far, training evaluation has however gained only limited attention at most companies investing in different training programs. Uponor corporation has initiated a large ERP implementation and process harmonization program in 2004. Thousands of end-users have been trained during this project so far, and the work still continues until the project is completed in 2010. In this thesis, the evaluation of end-user training in Uponor’s ERP program is brought further from the current state of performing the basic participant satisfaction survey in the end of each class. The results show that in order to reach reliable training effectiveness evaluation results, not only the reaction towards training but also transfer of skills and attitudes and the final results of the training program should be evaluated.

Improving and User Interface to E-Procurement Software Used in Asset Accounting and Investigating Effects to Efficiency

This diploma thesis has been done to international organization which takes care from the accounting actions of two major companies. In this organization are used three different purchasing tools which are used when new asset master data is wanted to input to SAP R/3- system. The aim of this thesis is to find out how much changing the user interface of one of these three e-procurement programs will affect to overall efficiency in asset accounting. As an addition will be introduced project framework which can be used in future projects and which help to avoid certain steps in the development process. At the moment data needs to be inputted manually with many useless mouse clicks and data needs to be searched from many various resources which slow down the process. Other organization has better tools at the moment than the myOrders system which is under investigation Research was started by exploring the main improvement areas. After this possible defects were traced. Suggested improvements were thought by exploring literature which has been written from usability design and research. Meanwhile also directional calculations from the benefits of the project were done alongside with the analysis of the possible risks and threats. After this NSN IT approved the changes which they thought was acceptable. The next step was to program them into tool and test them before releasing to production environment. The calculations were made also from implemented improvements and compared them to planned ones From whole project was made a framework which can be utilized also to other similar projects. The complete calculation was not possible because of time schedule of the project. Important observation in the project was that efficiency is not improved not only by changing the GUI but also improving processes without any programming. Feedback from end user should be also listened more in development process. End-user is after all the one who knows the best how the program should look like.

O núcleo de estudos em Filosofia e Saúde da Fundação Educacional Serra dos Órgãos: interfaces na formação médica

Nos últimos anos, inúmeros problemas surgiram na área da saúde em decorrência, sobretudo, dos avanços ocorridos no campo das biotecnociências. Percebendo-se a exigüidade de espaço, no atual currículo médico, para a discussão de muitas dessas questões, alunos e professores da Fundação Educacional Serra dos Órgãos (FESO) propuseram a criação do Núcleo de Estudos em Filosofia e Saúde (NEFISA), espaço destinado a fomentar o debate, o ensino e a pesquisa sobre os assuntos que tenham sua emergência na interface da Filosofia com a Medicina e a Saúde. O escopo do presente artigo é apresentar o trabalho desenvolvido no NEFISA-FESO.

Meio ambiente e saúde no Programa PET-Saúde: interfaces na atenção básica

A degradação ambiental vem modificando nosso cenário de forma acelerada, interferindo negativamente no processo saúde-doença. É essencial discutir a temática saúde ambiental com profissionais de saúde, sendo o Programa PET-Saúde um facilitador, e as unidades de Estratégia de Saúde da Família (ESF) um excelente cenário. Propõe-se analisar a percepção de profissionais de saúde e usuários sobre a temática em duas unidades de ESF (Botucatu/SP) e sensibilizá-los por meio de discussões teóricas e vivências. Foram entrevistados 45 profissionais e 36 usuários, sendo 21 indicados pelos agentes comunitários de saúde como tendo boa relação com o meio ambiente e 15 indicados por não apresentarem boa relação com o mesmo. Aplicou-se o referencial da metodologia qualitativa, utilizando-se o Discurso do Sujeito Coletivo. Todos demonstraram ter consciência dos problemas ambientais e de saúde e o que poderia ser feito para melhorar a situação, mas são raras as ações realizadas nas unidades. Reforça-se a necessidade de capacitar equipes em Saúde Ambiental, estimulando a adoção de práticas transdisciplinares que superem as práticas assistencialistas e caminhem no sentido da promoção, além de empoderar a população para lutar e ser responsável por um meio ambiente mais equilibrado, melhorando a qualidade de vida.

Integrating user experience into early phases of software development

The value and benefits of user experience (UX) are widely recognized in the modern world and UX is seen as an integral part of many fields. This dissertation integrates UX and understanding end users with the early phases of software development. The concept of UX is still unclear, as witnessed by more than twenty-five definitions and ongoing argument about its different aspects and attributes. This missing consensus forms a problem in creating a link between UX and software development: How to take the UX of end users into account when it is unclear for software developers what UX stands for the end users. Furthermore, currently known methods to estimate, evaluate and analyse UX during software development are biased in favor of the phases where something concrete and tangible already exists. It would be beneficial to further elaborate on UX in the beginning phases of software development. Theoretical knowledge from the fields of UX and software development is presented and linked with surveyed and analysed UX attribute information from end users and UX professionals. Composing the surveys around the identified 21 UX attributes is described and the results are analysed in conjunction with end user demographics. Finally the utilization of the gained results is explained with a proof of concept utility, the Wizard of UX, which demonstrates how UX can be integrated into early phases of software development. The process of designing, prototyping and testing this utility is an integral part of this dissertation. The analyses show statistically significant dependencies between appreciation towards UX attributes and surveyed end user demographics. In addition, tests conducted by software developers and industrial UX designer both indicate the benefits and necessity of the prototyped Wizard of UX utility. According to the conducted tests, this utility meets the requirements set for it: It provides a way for software developers to raise their know-how of UX and a possibility to consider the UX of end users with statistical user profiles during the early phases of software development. This dissertation produces new and relevant information for the UX and software development communities by demonstrating that it is possible to integrate UX as a part of the early phases of software development.
