This study covers and analyzes the contents of Tridimensional Graphic Geometry, Technical Drawing 3 and Descriptive Geometry in the BSc course in Civil Engineering, in order to create an integrated assessment model across these disciplines from the use of specific computer graphic softwares. It is proposed to use computer graphic for： （i） concept formation, （ii） completing and/or reviewing the content, （iii） creation of a database with virtual geometric models and their applications in Engineering and for the studies of their representations, geometric properties, etc., providing digital images of everyday forms and objects. In order to begin the diagnosis of the current situation, we gave an open questionnaire to 65 students from the 16 groups of three-dimensional graphical geometry, 20 students from the two courses in Technical Drawing 3 and 35 students from the three Descriptive Geometry classes. The analysis of the data suggests that students better understand the two-dimensional representations of three-dimensional models through their modeling with the computer graphics software used, and the association of abstract concepts with concrete content. From the analysis of the data we can verify that when our students enter the foundation Engineering courses, the main difficulty in the disciplines of drawing is the three-dimensional visualization. The hypothesis is that the student will better understand the two-dimensional representations of three-dimensional models through their modeling with the computer graphic software used and the association of abstract concepts with concrete content.展开更多

But severely steatotic liver grafts are associated with a high risk of intraoperative and postoperative complications. Accurate assessment of fat content of donor livers and monitoring of the extent of steatosis in recipients are required for liver transplantation. The present study aimed to determine the correlation between liver echogenicity and fat content, and to evaluate the use of an ultrasonic integrated backscatter system（IBS） in the assessment of changes in fat content after liver transplantation.METHODS： Seventy-nine consecutive patients receiving liver grafts from living donors were evaluated in our center. Of these recipients, 67 survived for more than two years and were included in this study. Each liver graft was evaluated with IBS and ultrasound before operation and the fat content was estimated. The fat content of the grafts in the recipients was again assessed with ultrasound at 18 months after surgery.RESULTS： A correlation was detected between each graft＇s IBS value and its fat content（P=0.001）. The IBS value in fatty grafts with various degrees of steatosis was significantly decreased in 3（P=0.02）, 12, 15 and 18（P=0.001） months after orthotopic liver transplantation. The IBS value returned to normal in all patients in 18 months after liver transplantation.CONCLUSIONS： Decreased fat content in steatotic grafts can be observed in all recipients. Ultrasonic IBS is useful in determining the steatotic degree of grafts in donors as well as in monitoring the grafts after liver transplantation.展开更多

It is here suggested that the combination of tandem learning, various communication activities performed on-line, and standard courses help mature students to boost their self-esteem, give them more autonomy, and enhance their motivation. Tandem learning, which is based on the principles of reciprocity and autonomy, is ideally suited for adult students. It helps overcome the problems connected to the affective reactions of adults, and at the same time, being content driven, offers a more natural setting to learn an L2 （second language） on a mutual supportive basis.展开更多

The claim of this research is that a procedural syllabus based on texts and tasks facilitates both the acquisition of Italian as a foreign language and the integration of language and content. Each text proposed to the learners was accompanied and enhanced by pre-, while-, and production-tasks. A particular emphasis was assigned to noticing and attention management tasks in the pre and while phase Production tasks in a later phase favoured interlanguage development by combining representational structures with controlled attention. The method of the study was a combination of qualitative and quantitative approach at any stage. Measures for written production during the course and to assess final exams were： Holistic Rating （fluency and creativity）, Accuracy Ratios （intelligibility index and error index）, and Complexity Ratios （dependent and coordinate clauses per t-units ratio and re-elaboration of a model or text type）. At the final exams, Texts and tasks learners outperformed non-texts and tasks learners. In conclusion, an input related to personal and/or academic interests, to be processed through tasks, allowed learners a rapid interlanguage change and development展开更多
