This review presents a summary of existing visitor monitoring methods and relevant studies in land and marine-based areas, with a focus on the application to unique aquatic settings. Various opportunities and challenges exist with respect to the use of each method in different marine settings. These methods differ in terms of the complexity, costs, level of accuracy, and detailed information they provide. Furthermore, the feasibility of applying these methods also depends on the site attributes of a marine area. Since each marine area varies in geographical scale and environmental and social conditions, some methods will be more appropriate or perform more successfully than others in a particular location. Therefore, the consideration of these methods should be part of a proposed alternative process, focused on adaptive monitoring that scales to address visitor ebbs and flows in these aquatic areas. The proposed alternative seeks to develop consensus around quantitative goals for visitor monitoring and estimating techniques in marine settings, using a customizable mix of methods and techniques. This alternative effort progresses to subsequent tasks and discussions, and recommendations are made considering the feasibility and confidence of using these methods in particular marine settings and future pilot sites.

Abstract The realistic state of the education of the Roma community illustrates the need for serious investments in resources of a human and material kind. Although the recent decade proved to be a decade of educational needs of the Roma, analyses still show the necessity for sustaining the continuity in advancing the developments of everything connected to early childhood development, as a basic sub-system in education. The research that was done had the aim of exploring the needs for strengthening the competencies and the sensibilities of work in environments with social, language and cultural specificities. The research was conducted in several stages, with focus groups as well: a questionnaire for kindergarten educators was conducted; research with a focus group of kindergarten educators was conducted; research with a focus group of parents whose children attend the kindergarten was conducted; research with a focus group of NGO representatives was conducted. The methods and techniques applied are the method of analysis, the inductive, descriptive and the method of generalization, as well as techniques of analysis of pedagogical documentation, observation,and surveying. It can be concluded that: kindergarten educators show a need towards professional development and training related to early childhood development and learning; kindergarten educators show a need towards cooperation with the community; parents showed their dissatisfaction withthe difficult adaptation of children in the kindergarten; NGO representatives stated the need for infrastructural investments, as well as investments in joint project activities between the children, educators,and parents.

Abstract This paper presents decapsulation solutions for devices bonded with Cu wire. By removing mold compound to a thin layer using a laser ablation tool, Cu wire bonded packages are decapsulated using wet chemical etching by controlling the etch time and temperature. Further, the paper investigates the possibilities of decapsulating Cu wire bonded devices using full wet chemical etches without the facilitation of laser ablation removing much of mold compound. Additional discussion on reliability concerns when evaluating Cu wirebond devices is addressed here. The lack of understanding of the reliability of Cu wire bonded packages creates a challenge to the FA engineer as they must develop techniques to help understanding the reliability issue associated with Cu wire bonding devices. More research and analysis are ongoing to develop appropriate analysis methods and techniques to support the Cu wire bonding device technology in the lab.
