Waste management system needs a clear and strict management policy. They also need a process of evaluating and selecting the most appropriate landfill sites that respect the restrictions and constraints dictated by the presence of the population in that area, with respect to ecological ecosystems and other factors. In addition to the geographical and geological criteria and other specifications that are defined by traditional selection procedures, there are new factors adding to the old constraints and limitations. Urban waste is produced in large quantities in our cities, every year. As a result, the number of sites should increase with the population growth as well as the increase in urban waste products. On the other hand, the eligibility criteria and adding constraints and limitations make it more difficult to choose suitable sites. Environmental and local and state regulations limit the number of choices as well as areas and volume of sites making their selection more difficult, posing a real challenge for specialists. Specialists need to use the Geographic Information System (GIS) as well as the method of Multiple Critical Decision Analysis (MCDA) to select the most optimal location. Our study aims to apply MCDA integrated with GIS to select potential sites for urban waste deposition. The method of hierarchy analysis (AHP) will be used to weight and rank the constraints and criteria. This article is part of a potential project we are working to propose to Berat County, Albania.

We are used to the traditional methods of teaching mathematics. The textbook, the blackboard and a chalk have been for centuries a wonderful part of teaching. And, they always will be. Traditional teaching methods of mathematics are a wonderful legacy of our educational system that have educated generations of teachers, engineers, administrators, managers, leaders, and economists. American universities websites, the video-lectures of the best professors of well-known disciplines such as statistics, operational research, number theory, algebra, game theory, show impressing large blackboards, all over the auditor's walls. We always will need and admire traditional mathematics. But, beyond the lessons, especially in applied disciplines, students need to learn the software created for discipline applications. Making IT students to learn and, more important, to create applications and programs following the theoretical lessons is a useful way to help them understand better the theoretical knowledge. Similarly, other "theoretical" math disciplines such as number theory, game theory, geometry can be used to. The idea of making a group of IT students and the professor to create a package of applications for the math courses is a very useful process to a more advanced stage of teaching.

Learning Management Systems is a challenge of implementing information technology (IT) in the higher educational field. This paper introduces a framework for assessing an LMS by integrating partial last squares-structural equation modeling (PLS-SEM) and fuzzy analytic hierarchic process with Z-numbers (Fuzzy Z-AHP). The objective is to propose the combination of the two approaches via results of PLS-SEM for the construction of the decision matrix for Fuzzy Z-AHP. The PLS-SEM method was used firstly to evaluate the conceptual model Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and extracting the significant connections between the independent constructs and the behavioral intention to use an LMS. Secondly is adapted the Fuzzy Z-AHP method to rank the independent significant constructs initializing from the PLS-SEM results. Using a questionnaire survey, the study sampled 530 users of LMS in 4 Albanian universities as respondents. To the best of our knowledge this paper is among the first that combines PLS-SEM with Fuzzy Z-AHP for the UTAUT2 model while using an LMS. This combination showed that the most important construct of UTAUT2 affecting behavioral intention to use an LMS was habit. This study assist the decision makers and policy makers to provide the means to obtain better managerial conclusions for the improvement and progress of an LMS.
