Problems in the mobile services are complex where the lack of the user analysis is not the modest issue. User centered design has increasingly become as a basis for the design of mobile services. The concept of user centered design gives end-user extensive attention at each stage of the design process. Mobile service providers want to offer experiences for users and clearly the users look for services that can provide pleasant experiences. In this thesis, the elements of user experience in mobile internet were studied as well as user experience measuring methods were researched. This study was looking for user experience measuring metrics and methods to specify new factors to measure user experience. During this thesis research project an application called CEM4Mobile was designed and implemented. CEM4Mobile is an application for observing and analysing user experience based on the user activity and behaviour. As a result of this thesis, a collection of user experience elements and measuring metrics were found. The elements and metrics were designed and implemented to CEM4Mobile product, which measures user experience. It was found out that the user experience measuring methods were based on interaction between two people but CEM4Mobile makes user observation programmatic.

Many researchers and professionals have reported nonsubstance addiction to online entertainments in adolescents. However, very few scales have been designed to assess problem Internet use in this population, in spite of their high exposure and obvious vulnerability. The aim of this study was to review the currently available scales for assessing problematic Internet use and to validate a new scale of this kind for use, specifically in this age group, the Problematic Internet Entertainment Use Scale for Adolescents. The research was carried out in Spain in a gender-balanced sample of 1131 high school students aged between 12 and 18 years. Psychometric analyses showed the scale to be unidimensional, with excellent internal consistency (Cronbach"s alpha of 0.92), good construct validity, and positive associations with alternative measures of maladaptive Internet use. This selfadministered scale can rapidly measure the presence of symptoms of behavioral addiction to online videogames and social networking sites, as well as their degree of severity. The results estimate the prevalence of this problematic behavior in Spanish adolescents to be around 5 percent.

Research into online addictions has increased substantially over the last decade, particularly amongst youth. This study adapted the Problematic Internet Entertainment Use Scale for Adolescents [PIEUSA] for use with a British population. The adapted scale was used to (i) validate the instrument for English-speaking adolescent samples, (ii) estimate the prevalence of adolescent online problem users and describe their profile, and (iii) assess the accuracy of the scale"s classification of symptomatology. A survey was administered to 1097 adolescents aged between 11 and 18 years. The results indicated that (i) reliability of the adapted scale was excellent; factor validity showed unidimensionality, and construct validity was adequate. The findings also indicated that (ii) prevalence of online problem users was 5.2% and that they were more likely to younger males that engaged in online gaming for more than two hours most days. The majority of online problem users displayed negative addictive symptoms, especially"loss of control" and"conflict". The adapted scale showed (iii) very good sensitivity, specificity, and classification accuracy, and was able to clearly differentiate between problem and non-problem users. The results suggest certain differences between adolescent and adult online problem users based in the predominance of slightly different psychological components.

Los estudios sobre emprendimiento desde la perspectiva de género, es un ámbito que ha ido incrementado en los últimos años, la evidencia que más del 50% de la población mundial son mujeres pero que ellas son propietarias y gestionan una proporción de negocios muy inferior que los hombres y que existen diferentes estilos de gestión según el género, han impulsado el estudio de variables explicativas de las características distintivas entre hombres y mujeres en el ámbito del emprendimiento. El objetivo de esta revisión bibliográfica, es presentar un análisis de la literatura que refleja el interés de mujeres empresarias en Internet. La revisión se basa en investigaciones académicas publicadas sobre el tema, y se complementa con un resumen de la literatura "gris", basada en las fuentes encontradas en Internet. Consideramos que existe una clara necesidad de revisar la literatura existente para conocer el caso de las mujeres que han establecido un negocio en Internet, y para indicar una nueva dirección de futuros estudios, y concluimos que existe una escasez de la investigación académica en el área, una clara falta de conocimiento acumulado junto a teorías y propuestas explicativas.

El objetivo principal de este trabajo es determinar si las comunidades virtuales de práctica son un espacio adecuado para la autoformación de los docentes. Con este fin, primero se especifican algunos conceptos clave que ayuden a contextualizar el tema de la formación; en segundo lugar se recogen los rasgos que se consideran hoy necesarios para llevar a cabo la labor docente, dibujándose así el perfil “ideal” del profesor en el contexto actual desde distintos ángulos de vista; y por último, se narran algunas experiencias personales en las redes sociales para ilustrar el funcionamiento de este nuevo paradigma social.

El vincle entre família i escola és un aspecte clau en el clima d’aula, el clima de centre i l’èxit acadèmic. A la vegada ens trobem davant impediments, ja sigui de conciliació familiar i laboral o de prejudicis en la relació entre família i escola, que dificulten aquest vincle. D’altra banda ens trobem davant una societat de la informació i el coneixement que avança a un ritme accelerat i que ofereix il·limitades propostes d’intercanvi i comunicació. La present recerca pretén donar a conèixer quines funcions tenen les aplicacions d’internet en la relació família i escola. En segon lloc, l’estudi identifica els factors i les limitacions que condicionen aquesta relació. Finalment, la recerca proposa possibles pràctiques inclusives entorn les aplicacions d’internet, que poden contribuir a millorar el vincle entre escola i família, com també en el clima d’aula, el clima de centre i l’èxit acadèmic.

In a very short time, the Internet has become an enormous source of information for teachers and students alike, in various scientific fields and at different levels of education. However, not all of this information is as reliable as one would wish and it is not always presented in the right way, nor is the content suitably structured for our purposes. Teachers need easily accessible criteria for selecting, analysing and evaluating web pages for their students, while bearing in mind the level and the material they are working with. In this article, we present the fundamental steps towards the analysis and subsequent evaluation of web pages of interest in the teaching of the Earth Sciences at different levels of education: Primary Education, Obligatory Secondary Education and “Bachillerato” (Pre-University Education)

The internet is an important tool for obtaining information. It offers vast amounts of information ranging from basic to advanced, from general to specific. Nevertheless, its quality cannot be classified or graded. Furthermore, some technical and/or specific information may not be available for free. This work primarily shows the great utility of the internet for getting suitable information in Chemistry and emphasizes open access and quality sites in Chemistry. It directs the reader towards many useful sites within some branches of Chemistry that provide powerful tools of research and study that may not be obtained easily at a library.

En los últimos años se ha producido un incremento del uso de la telefonía móvil e Internet con fines intimidatorios o simplemente para amenazar a los iguales en los centros escolares de nuestro país. Con la voluntad de aportar datos que puedan ayudar a su prevención, se ha realizado un estudio de encuesta en el que se ha obtenido información relativa a las amenazas recibidas a través de los nuevos medios de comunicación, es decir, Internet y la telefonía móvil. Los resultados indican que un 23.3% de los estudiantes de los centros públicos de Enseñanza Secundaria Obligatoria de la ciudad de Girona (Cataluña), durante el curso escolar, han recibido vía Internet o telefonía móvil algún mensaje que, por su contenido, ha supuesto una amenaza para su bienestar. Se analizan las consecuenciasemocionales y las estrategias de afrontamiento utilizadas por parte de estos adolescentes

Tutkielman tarkoituksena on selvittää, kuinka internet-palvelu kehitetään. Palveluiden kehitysprosessia tutkitaan erityisesti palveluiden kehityksen prosessisyklimallin mukaan ja empiirisessä osiossa sovelletaan teoriaosiossa käytyjä asioita musiikkialan yritykseen. Tutkielman pääongelma on, kuinka musiikkialan internet-palvelu kehitetään. Työn analysointimenetelmä on kvalitatiivinen ja aineisto kerätään sähköpostitse teemahaastatteluina. Palveluiden prosessisykli soveltuu hyvin internet-palveluiden kehityksen kuvaamiseen internetin nopeatempoisen muutostahdin takia. Prosessisyklin vaiheisiin kuuluu suunnittelu-, analyysi-, kehitys- ja lanseerausvaiheet. Internetissä kuluttajien ottaminen mukaan kehitysprosessiin on oleellista. Yritysten tulee myös huomioida, että lanseerausprosessiin tulee varata riittävästi resursseja. Jatkossa tutkimuksissa kannattaa keskittyä erityisesti internetin tuomiin erityispiirteisiin palveluiden kehityksen kannalta.

Tämä tutkimus keskittyy Venäjän kryptografian standardeihin ja niiden toteutukseen sertifioiduissa tuotteissa. Tässä työssä myös pohditaan menetelmiä, jotka parantavat suorituskykyä. Tutkimus jatkuu turvallisuuspalveluiden toimittajien vertailulla niitten saadun sertifikaattimäärän perusteella. Tämä auttaa arvioimaan Venäjän nykyistä markkinatilannetta. Sen lisäksi työssä kuvataan venäläisten algoritmien integraatiota TLS-, PKI- ja IKEv1-protokolleihin. Tavoitteena on protokollien yhteensopivuus erilaisiin tuotteisiin. Diplomityötä jatketaan tutkimalla IKEv2-protokolan integroinnin vaatimuksia. Lopuksi diplomityössä todetaan, että venäläiset algoritmit ovat turvallisia ja standardisointi auttaa ulkomaisia yrityksiä saamaan tarvittavat sertifikaatit.
