Cause-effect graphing is a commonly used black-box technique with many applications in practice. It is important to be able to create accurate cause-effect graph specifications from system requirements before converting them to test case tables used for black-box testing. In this paper, a new graphical software tool for creating cause-effect graph specifications is presented. The tool uses standardized graphical notation for describing different types of nodes, logical relations and constraints, resulting in a visual representation of the desired cause-effect graph which can be exported for later usage and imported in the tool. The purpose of this work is to make the cause-effect graph specification process easier for users in order to solve some of the problems which arise due to the insufficient amount of understanding of cause-effect graph elements. The proposed tool was successfully used for creating cause-effect graph specifications for small, medium and large graphs. It was also successfully used for performing different types of tasks by users without any prior knowledge of the functionalities of the tool, indicating that the tool is easy to use, helpful and intuitive. The results indicate that the usage of standardized notation is easier to understand than nonstandardized approaches from other tools. Index terms-software quality, black-box testing, cause-effect graph, graphical software tool.

Self-Sovereign Identity (SSI) is a novel and emerging, decentralized digital identity approach that enables entities to control and manage their digital identifiers and associated identity data fully while enhancing trust, privacy, security, and the many other properties identified and analyzed in this paper. The paper provides an overview and classification of the SSI properties, focusing on an in-depth analysis, furthermore, presenting a comprehensive collection of SSI properties that are important for the implementation of the SSI system. In addition, it explores the general SSI process flow, and highlights the steps in which individual properties are important. After the initial purification and classification phase, we then validated properties among experts in the field of Decentralized and Self-Sovereign Identity Management using an online questionnaire, which resulted in a final set of classified and verified SSI properties. The results can be used for further work on definition and standardization of the SSI field.

UDK: 630*9(497.6 Unsko-sanski kanton)“2003/2013“ Investments in forest sector represent an important issue that is regulated by legislation. Legislative framework that regulate forest sector in the Federation of Bosnia and Herzegovina has been changing recently - from the Law on Forests of the Federation of Bosnia and Herzegovina (2002 – 2009), Forest Regulation of the Federation of Bosnia and Herzegovina (2009 – 2012) and finally cantonal Laws on Forests (2012 to date). Cantonal laws currently represent the only valid legislative documents that regulate forest sector in the Federation of Bosnia and Herzegovina. This paper analyse the investments in the public forests at the territory of Una-Sana Canton, managed by forest management enterprises "Unsko-sanske šume", within the period 2003-2013 in dependence of the valid legislative frameworks. Having in mind the various regulations that prescribed the financing of the biological investments, scope and structure of the performed activities together with the amount of invested funds have varied between particular periods. The biggest share in total investments to forest sector belongs to the silvicultural measures (66%) and forest road construction (17%). The analysis included the trend of realised biological investments and invested funds. It reveals the mutual incompatibility that causes the differences in unit costs of biological investments in various periods. This implies the need for creation and implementation of unique methodology for cost calculation respecting the basic principles of econometrics. Conducted analysis indicated that previous legislative frameworks did not prescribe appropriate financing model. One should bare in mind this fact during the prescription of new financing model in the ongoing proposal of new Law on Forests of the Federation of Bosnia and Herzegovina.

Methods for automatic analysis of user interfaces are essential for a wide range of applications in computer science and software engineering. These methods are used in software security, document archiving, human-computer interaction, software engineering, and data science. Even though these methods are essential, no single research systematically lists most of the methods and their characteristics. This paper aims to give an overview of different solutions and their applications in the separate processes of automatic analysis of user interfaces. The main focus is on the techniques that analyze web page layouts and web page structure. Web pages' style, type of content, and even structure constantly (often drastically) change, as do methods that analyze them. The fact that most methods use very different datasets and web pages of various complexities are some of the reasons that the direct comparison of methods is difficult, if not impossible. Another fact is that the vast applications of methods practically solve similar problems. With these facts in mind, in the paper, we surveyed relevant scientific articles, categorized them, and provided an overview of how these methods have developed over time.

UDK: 630*93:630*68(497.6) Illegal logging and related trade represent one of the most important forest-related issues at international policy scene. In 2002, the European Union had initiated establishment of regional initiatives on preventing trade of illegally harvested wood, well known as FLEGT process. Other important segment of European Union efforts is adoption of legally-binding Regulation No. 995/2010 - EU Timber Regulation (EUTR) that prohibits import of illegally harvested wood and their products into EU. Bosnia-Herzegovina is country with economy in transition and with relatively slow progress toward EU integration process, while rising of awareness on need for prevention and combat with illegal activities and corruption represent one of the mayor challenges for its society. This paper analyse forestry professionals’ awareness of the EU Timber Regulation in the Federation of Bosnia-Herzegovina as precondition for planning further steps on improving human and institutional capacities in forest sector to prevent and combat with illegal activities. In order to conduct the analysis of forestry professionals’ awareness on EUTR, survey was conducted among currently employed forestry professionals in forest sector of the FB-H. Results revealed that employed forestry professionals in the FB-H have different level of awareness on EUTR. Therefore, creation and consistent implementation of informational forest policy instruments are needed in order to increase capacities of forestry professionals related to elements of EUTR implementation process. Efforts on prevention and combat with illegal activities in forest sector should involve implementation of mix of forest policy instruments directed toward harmonization of forest policy in the FB-H with EUTR requirements based on active participation of forestry professionals that are aware of EUTR implementation process and its potential influences on forest and wood-processing sectors of the FB-H.
