With a practical example of recycling engines of end-of-life vehicles ,the validity of the recycle economy model and good recycle economy of the end-of-life vehicle engine were justified. It is concluded that ① remanufacture-ability of the part or component of the vehicles; ② the organization and management level of a recycle corporation; ③ policies and regulations of the government are crucial factors to raise the recycle economy of the end-of-life vehicle.展开更多

Indeed they meet the need to implement techniques and management tools which are able to improve the culture-tourism binomial. This would permit to transform into valid instruments of national economical development, the shared declaration of intents for which culture and tourism, especially in Italy and in this particular fragile period, represent even more the main strategic levers for the sustainable development. This article intends to describe the potentiality of these widespread hotels as innovations particularly suitable with trends recently emerged in tourism sector and outline the phenomenon pattern in ltaly with particular attention on Umbria region, in order to identify his main strength and weakness and some innovation to improve performance. To this end, it starts from the analysis of the national and international economic-managerial literature concerning in particular cultural and experienced trends shown in tourism. Then it introduces the main acquisitions about widespread hotels in Italy, updating and extending them through a desk survey based on indirect sources of various natures. Lastly, it describes the case of Umbria, analyzing more in depth making use of interviews with entrepreneurs/managers of hotels and based on a semi-structured questionnaire. The aspects of indeterminateness which were found, starting from the normative one, testify how the potentiality of the widespread hotels as far as regards the value creation for the enterprise itself and the territorial stakeholder, are still not properly understood and therefore used. It is clear that, therefore, new behaviors are needed for entrepreneurs and, most importantly, for local policy makers in order to create the conditions for the full success of these hospitality models.展开更多

This corrective machining has an influence on accuracy and efficiency and is an important factor. The measurement system for measuring the forms of die and mold at all times is essential in order to machine the die and mold with high accuracy and efficiency. However, the problems of management and operation errors are found in compensating process of die and mold machining. In this paper, an online machining and measurement system in die and mold manufacturing is developed in order to overcome these problems. In this online system, 2-axis control system is added to a surface roughness measuring instrument, and both NC machining program and measured data are linked and controlled using a same computer. Therefore, the machining and measurement can be recognized for consistent process, and can be realized on the machine. This system has the advantages such as the high accuracy, low-price, and online convenience and so on. The possibility of practical use of this online system was investigated by fundamental experiments.展开更多
