The latest developments of mobile devices include a variety of hardware features that allow for more rich data collection and services. Numerous sensors, Internet connectivity, low energy Bluetooth connectivity to other devices (e.g., smart watches, activity tracker, health data monitoring devices) are just some examples of hardware that helps to provide additional information that can be beneficially used for many application domains. Among others, they could be utilized in mobile learning scenarios (for data collection in science education, field trips), in mobile health scenarios (for health data collection and monitoring the health state of patients, changes in health conditions and/or detection of emergency situations), and in personalized recommender systems. This information captures the current context situation of the user that could help to make mobile applications more personalized and deliver a better user experience. Moreover, the context related information collected by the mobile device and the different applications can be enriched by using additional external information sources (e.g., Web Service APIs), which help to describe the user’s context situation in more details. The main challenge in context modeling is the lack of generalization at the core of the model, as most of the existing context models depend on particular application domains or scenarios. We tackle this challenge by conceptualizing and designing a rich generic context model. In this thesis, we present the state of the art of recent approaches used for context modeling and introduce a rich context model as an approach for modeling context in a domain-independent way. Additionally, we investigate whether context information can enhance existing mobile applications by making them sensible to the user’s current situation. We demonstrate the reusability and flexibility of the rich context model in a several case studies. The main contributions of this thesis are: (1) an overview of recent, existing research in context modeling for different application domains; (2) a theoretical foundation of the proposed approach for modeling context in a domain-independent way; (3) several case studies in different mobile application domains.

The mission of the Gareganze's Brothers in Christ Church facing the chaos of the socio-political situation in DRC resulting mostly from the question of the Congolese nationality is to dynamise the christian mission and to protect the poor, set free the captives, because God is always at their side. The DRC, though, has enormous natural resources and the competent human resources capabilities. The national institutions seem to be unable to handle this situation because of the lack of political culture, mismanagement and moral untidiness. The successive Congolese crises mostly are the same, the common denominator resides in the causes that brought them about. The main objectives of the antagonist groups are political leadership and material wealth. The findings of our analysis will help the Church of Christ in Congo, to fulfill the prophetic mission and the vision of God, for the positive transformation of the Congolese society. / Christian Spirituality, Church History and Missiology / M.

La mission de la théologie africaine face à une situation socio-politique, culturo-économique catastrophique de l'Afrique, due essentiellement à la question de la spiritualité sociale, d'intelligence sociale et l'aliénation culturelle, est de redynamiser la mission chrétienne, stimuler la renaissance spirituelle africaine et défendre les pauvres et les opprimés, parce que Dieu est toujours du côté d'eux. En effet, l'homme africain et sa société peuvent toujours être au centre de l'engagement théologique et de l'église d'Afrique, pour l'évangélisation comme pour la promotion sociale. Parce que l'homme africain n'est pas seulement individu, il est aussi société et culture. De ce fait, L'église d'Afrique avec ses différentes formes de théologies, n'existe pas pour elle-même, mais pour annoncer la Bonne Nouvelle aux africains. Cependant, cette Bonne Nouvelle n'a aucune pertinence aux yeux des africains si elle tombe en dehors de l'essentiel de leur vie. En d'autres termes, une théologie africaine, quelle que soit sa forme, mais, sans promouvoir la libération totale spirituelle et physique de l'homme Africain et motiver la reconstruction de l'Afrique telle que prônée par Kä Mana n'a pas sa raison d'être. En plus, la théologie africaine peut également stimuler la vraie démocratisation des pays africaines comme principal enjeu de la pastorale théologique et politique des églises chrétiennes et religions traditionnelles africaines. Parce qu'au nom de la dignité de chaque personne, de l'amour de Dieu et l'amour du prochain, de la foi et du salut de tout homme, la théologie africaine ne peut négliger l'identité culturelle et anthropologique du terroir africain et le construit socioculturel inspiré de l'évangile. Cette théologie africaine peut également motiver la remise en question du néocolonialisme africain sous toutes ses formes. Dès lors, le résultat de cette étude peut aider le missiologue/théologien africain qui est l'église de Dieu à bien accomplir sa mission prophétique selon la vision de Dieu, dans le but de transformer spirituellement et physiquement l'Afrique, aussi reconstruirer positivement la société africaine. Evidemment, le développement intégral de l'homme africain, selon moi, suppose le respect de la dignité humaine qui ne peut se réaliser que dans la justice, la paix, l'auto-transformation personnelle, l'éthique et une inculturation personnifiante. Summary The mission of african theology facing African socio-polical, cultural and economic catastrophe that due mainly to social spirituality, social intelligence and cultural alienation, is to revitilise christian mission, stimulate spiritual african renaissance and to defend the poor and oppressed, people by whom God always stands. Of course, the african and their community should always be at the heart of the theological engagement and of the action of the African church concerning evangelism as well ass social promotion. For the African embodies both his or her society and culture. Therefore, the African church and all their different theologies do not exist for their on sake, but rather for the African people to whom they should bring the good news. This good news is not relevant for the Africans as long as it does not deal with their main concern. In other words, whatever the forms of African theology, as long as it overlooks the complete liberation of the Africans, freeing them spirituality, promoting their spiritual and physical liberation and motivating the reconstruction of Africa as promoted by Kä Mana here, it will serve no practical purpose. Besides, African theology has also to stimulate the democratisation of African countries as one of the targets of the African Christian churches and traditional religions. In the name of the dignity of each and every person, of the love of God and the love for the neighbour, that of faith and salvation of the humankind, African theology is not expected to neglect cultural and anthropological identity of the Africans terror and the sociocultural construct inspired by the Gospel. African theology can thus motivate the questioning of African neocolonialism in all its forms. The result of this study can help African missiologists and theologians that are the church of God to fulfil well the prophetic mission after the vision of God, so as to bring about spiritual and physical transformation, and positively reconstruct the African society. As for me, the integral development of the African supposes the respect of their human dignity that can be materialised through peace, justice, personal sel-transformation, ethics and personifying inculturation. / Christian Spirituality, Church History and Missiology / D.
