This work presents development of Human Resource Management System based on analysis of modern development trends as well as fundamentals of key functions and data structures of human resource management systems in organizations. Introduced general-purpose model meets the requirements of human resource management systems and fits for the organizations of any size and structure. The system, mentioned above, was designed using ICONIX, Martin-Odell, RUP, XP, UMM methodologies, tested using black and white box techniques and implemented by means of Lotus Notes/Domino SDK . Created software was installed for the trial period at the joint-stock company 'PTI Technologijos'. The conceptual part of the theses represents component interface specification technique capturing control flow rules. It describes a clear process for moving from business requirements to system specification and identifying system behavior rules conditioning interfaces of the system. Proposed model facilitates dealing with the change and substitutability of business rules, what can be achieved only if the system is properly specified. Interface specification technique was used in practice to design the interface between human resource management system and accountancy system.

This paper aims to introduce programming using Design by Contract (DbC) approach, its principles and implementations in different environments. The motivation for the creation of this approach is discussed in the beginning and the DbC metaphor is explained, as well as its application to programming. The description of major elements of the contract in the context of routine interface follows afterwards. The subject matter of this paper is the analysis and comparison of individual programming systems for DbC development with the help of code samples. The benefits of using this approach and its role in the modern development process are evaluated in conclusion.

Amongst the diversity of interface modalities, the tabletop tangible interfaces make the link between physical objects and virtual objects, making possible to "grasp" the interface and interact with it physically, also counting on multitouch interactions. However, in the development process of this kind of interface, there is a lack of specification s model that supports, not only the physical objects interaction, but multitouch interactions as well, and that organizes and classifies the specification in a more agile manner, easier to document and implement. Thus, this work presents a new tabletop tangible user interface specification model, TTUI-SM, that classifies and organizes the interface element specification within many components. A diagramatic tool, TTUI-SMT, was developed based on this model, aiming to make the interface specification and development faster, easier and automatized. To validate the model and tool, two studycases were introduced and specified. An experiment was conducted to evaluate both model and tool, resulting in the comprovation, through questionnaires analysis, of the proposed benefits. / No cenário de desenvolvimento de interfaces computacionais, os avanços nas pesquisas buscam oferecer novas formas de interação que se aproximam da forma natural com que o homem interage com o mundo real. Dentre as diversas interfaces avançadas, as interfaces tangíveis de mesa (tabletop), promovem a ligação entre objetos físicos e objetos virtuais, possibilitando ao usuário interagir com objetos digitais por meio do ambiente físico, e também por meio de interações multitoques. Entretanto, o processo de desenvolvimento deste tipo de interface carece de um modelo de especificação que contemple, além das interações por meio de objetos, interações multitoques e que organize e classifique a especificação de uma maneira mais ágil e mais fácil de documentar e implementar. Assim, este trabalho apresenta um novo modelo de especificação de elementos de interface tangível de mesa, denominado TTUI-SM, que organiza a especificação de elementos de interface em diversos componentes. Uma ferramenta diagramática, o TTUI-SMT, baseada neste modelo de especificação, também foi desenvolvida visando agilizar, facilitar e automatizar o processo de especificação da interface e do seu desenvolvimento. Para validar o modelo e a ferramenta, dois estudos de caso foram introduzidos e especificados. Um experimento foi conduzido para avaliar o modelo e a ferramenta e, por meio de questionários, os benefícios propostos foram validados.
