A produção de agregados para construção civil é o maior segmento mineral Brasileiro, em números de produção, sendo formada principalmente por pequenos e médios empreendimentos, normalmente utilizando técnicas e procedimentos obsoletos e pouco um nenhum planejamento tanto para extração quanto para o fechamento da mina. O fechamento de mina e posterior utilização da área ainda é um grande problema visto que existem muitas áreas mineradas em que o plano de fechamento de mina não foi executado, deixando assim um passivo socioambiental elevado, prejudicando a imagem da mineração. Existem diversos exemplos de sucesso em que antigas cavas foram utilizadas para a implantação de novos empreendimentos, como loteamentos, óperas e hotéis. Com o intuito de mostrar a importância do planejamento para fechamento e posterior utilização de área de mineração, bem como a análise ambiental e impactos da atividade na sociedade e meio ambiente, este trabalho tem o objetivo de desenvolver uma metodologia para auxiliar, principalmente o pequeno e médio produtor de agregados, sobre os impactos que o correto planejamento e manejo da operação têm sobre o retorno no uso futuro da área. Foram desenvolvidos diferentes cenários de usos futuros alternativos de uma área de mineração localizada no Litoral Norte do Rio Grande do Sul, que posteriormente foram comparados entre si em relação à recuperação mineral, impactos socioambientais, e retorno financeiro. Ao final do trabalho foi possível visualizar uma metodologia apropriada para a análise de impactos socioambientais e planejamento para preparação da área para o recebimento de novos empreendimentos. A partir destes métodos de análise dispõe-se de diversos cenários comparativos, podendo assim o empreendedor tomar a decisão mais correta em relação ao seu empreendimento minerário e futuros empreendimentos pós-fechamento. / Aggregate production for civil construction is the largest Brazilian mineral segment, in production numbers, consisting mainly of small and medium-sized enterprises, usually using obsolete techniques and procedures and little or no planning for both extraction and closure of the mine. The closure of mines and subsequent use of the area is still a major problem, there are many mined areas where the mine closure plan has not been implemented, thus leaving a high social and environmental liability, damaging the mining image, but there are several examples of use of deactivated mining sites for the implementation of diverse projects. In order to show the importance of planning for the closure and subsequent use of the mining area, as well as the environmental analysis of impacts of the activity on society and the environment, this work has the objective of developing a methodology to assist, especially small and medium aggregate producer, on the impacts that correct planning and management of the operation has on the future use of the area. Different scenarios of future uses of a mining area located in the Northern Coast of Rio Grande do Sul were developed, which were later compared to each other in relation to mineral recovery, socioenvironmental impacts, and financial return. At the end of the work it was possible to visualize an appropriate methodology for the analysis of socio-environmental impacts and planning to prepare the area to receive new projects. From these methods of analysis we have several comparative scenarios, so that the entrepreneur can make the most correct decision regarding his mining enterprise and future enterprises after the closing.

Under the four forces of opening up of domestic telecommunication market, breakthroughs in information and communication technology, changes in consumer demand, and supplier¡¦s race for economic efficiency, industry structures have transformed. What used to be three distinct industries of divergent directions of development ¡V network service (computers), telecommunication (telephones) and cable television (television), are interacting. The market is growing rapidly with combined digital flow of the three industries. Broadband internet played a key role in such transformation. ADSL broadband internet service has prospered in recent years. As the internet population approach maturity, the market has changed focus from quantity to quality. There are two major challenges to fixed network internet service providers are: To increase market share by attracting more customers to its service base, and retain customers to minimize loss of customers. Telecommunication service providers attract new customers by offering special prices with gifts, they retain customers by elevating switching cost and long term contracts. But the result of price-cutting competition was erosion of profit margin. Customer loyalty is also swayed by low prices met by competitors. Under such intense competitive environment, service providers are actively developing digital content and making investment in fiber optic broadband to mitigate loss. It is hoped that richer internet content and faster speed broadband can attract more customers and increase customer revenue contribution. The subject of this study are ADSL broadband internet users in the greater Kaohsiung area, the regions surveyed include Kaohsiung County and Kaohsiung City. A questionnaire was used as the data collection tool. The survey was conducted on a convenient sample. Data was analyzed using SPSS statistical software. The influence of customer¡¦s expected future benefits, overall customer satisfaction and marketing strategies on customer retention were investigated. Furthermore, the interaction effects were also reviewed. The results of the study are: I.The most important factor in influencing customer retention is overall customer satisfaction, followed by marketing strategy and customer¡¦s expected future use. Further results are derived from analysis: 1.Overall customer satisfaction, customer¡¦s expected future use and marketing strategy showed significant positive influence on customer retention. 2.The influence of overall customer satisfaction, customer¡¦s expected future use and marketing strategy on customer retention vary in strength. 3.Marketing strategy showed significant positive influence on overall customer satisfaction and customer¡¦s expected future use. 4.With respect to the degree of influence on customer retention, overall customer satisfaction showed greater influence than marketing strategy and customer¡¦s expected future use. II.Customers exhibit high expectations for future use¡C Telecommunication service provider satisfying the following ¡§customer¡¦s expected future use¡¨ will significantly enhance customer retention. 1.Provide value-adding services. 2.Provide more value-adding application content. 3.Offer better prices. 4.Exchange fiber optic with ADSL in the future at free of charge

This case study explored perceived artificial intelligence (AI) performance and intended future use (IFU) in users of AI-based applications. Users could become less motivated to use these applications if AIs do not clearly communicate their actions. A prototype, a user test, and a structured interview were iteratively developed. Eight students participated in the final iteration, which was thematically analyzed. The results indicate that an AI-based application that shows recommendations can positively affect perceived AI performance and IFU. Possibly, the recommendations increased users’ understanding of AI decisions, as well as their satisfaction. Therefore, recommendations could be a potential design element for increasing perceived AI performance and IFU. Finally, time-saving functionality is a design element that could lead to higher IFU in AI-based applications, possibly only for other tasks than examining recommendations. Further research needs to test these findings under different circumstances.
