AbstractIn urban noise mapping the accuracy of the simulation tools is often challenged by the complexity of the modeled scenario, particularly when its extent coincide with the whole city. In this paper, a meaningful case study is reported concerning the flyover highway “Aldo Moro” in Genoa. The particular morphology of the city and the location of the highway make it a significant test for analyzing the effectiveness of current modeling tools in simulating complex urban areas. Noise mapping has been implemented in accordance with the standardNMPB-Routes- 2008. Results have been then analyzed complying with the END. Next diverse computational methods have been compared, considering ISO 9613-2, NMPB-Routes-1996, and Harmonoise, and even different frequency partitions (octave band or one-third octave band) for the last two standards. The computational time for the different calculation methods has been analyzed. In order to get a reciprocal validation, the simulated noise maps have been finally compared with maps coming from on field measurements. In this way a case study helpful for public administrations and stakeholders facing similar issues is provided, defining the state of the art and the forthcoming perspectives.

Este artigo teve por objetivo demonstrar os problemas em relação à avaliação e seleção de fornecedores na Construtora XYZ localizada na cidade de Porto Alegre - RS, propondo algumas melhorias para a condução da avaliação e seleção de fornecedores. Tratou-se de um estudo de caso com bases de pesquisa exploratória e qualitativa. A amostra foi composta por três funcionários, sendo o Gestor de Suprimentos, o Analista de Compras e o Engenheiro de Obras. A coleta de dados ocorreu por meio de entrevistas em profundidade, com o objetivo de registrar as impressões desses profissionais acerca da avaliação e seleção de fornecedores. O artigo apontou falhas em relação aos critérios de seleção de fornecedores e no processo de avaliação de desempenho. As propostas de melhoria pontuaram segurança (procedência dos produtos ou serviços e dos atores), prazo (cumprimento de acordos em relação ao prazo de fornecimento), qualidade (composição dos materiais) e documentação (estabelecimento legal de laudos técnicos e legislação trabalhista). Este trabalho não tem como finalidade encerrar as discussões acerca da avaliação de desempenho de fornecedores, mas instigar a reflexão da temática para futuros estudos.Palavras-Chave: Seleção.

It was a case study with exploratory and qualitative research bases. The sample consisted of three employees, being the Supply Manager, the Purchasing Analyst and the Construction Engineer. The data collection took place through in-depth interviews, to record the impressions of these professionals on the evaluation and selection of suppliers. The article pointed out flaws in relation to supplier selection criteria and in the performance evaluation process. The improvement proposals highlighted the safety (origin of products or services and actors), deadline (compliance with deadlines), quality (composition of materials) and documentation (legal establishment of technical reports and labor legislation). This work does not aim to close the discussions about the performance evaluation of the suppliers, but to instigate the reflection of the theme for future studies.Keywords: Selection.

The fire incident in karaoke buildings in Indonesia which claimed many lives has occurred several times. According to the National Academy of Science US, the smoke toxins that come out of the fire disaster cause 50-80% of deaths. Refers to the data, it is necessary to check further about the building material response to fire during a fire incident. Masterpiece Signature Karaoke is a karaoke building that classified as large and magnificent in the city of Medan which has various material so that it is necessary to study the interior material as passive fire protection. The purpose is to find out how to assess the reliability of fire passive protection regard to the interior materials and recommendations or descriptions of right interior material planning using the Analytical Hierarchy Process (AHP). This method is efficacious to solve the problem of reliability in using interior materials as passive fire protection in Masterpiece Signature Family KTV Medan building with the results of an Adequate Level of reliability. Then, design recommendations were given for the use of interior materials in karaoke building to improve the reliability results to be better.The results are useful as information for other researchers and karaoke buildings regarding passive fire protection systems at the Masterpiece Signature Family KTV Medan.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.
