Abstract: We consider a class of models of chemotactic bacterial populations, introduced by Keller-Segel. For those models, we investigate the possibility of chemotactic collapse, in other words, the possibility that in nite time the population of predators aggregates to form a delta-function (Dirac). To study this phenomenon, we applied the new numerical approximation called ziti's -method, which may or may not blow-up (in nite time), depending on the relative strength of three mechanisms in competition: (i) the chemotactic attraction of bacteria towards regions of high concentration in substrate (ii) the rate of consumption of the substrate by the bacteria and (iii) (possibly) the diusion of bacteria or the substrate. Our results are compared by the self similar (exact solution) obtained in [25].

Abstract: Most of the information dissemination is taking place through Web sites and Web portals. The effectiveness and efficiency with which information can be disseminated is very much dependent on the quality of the WEB site. The more the quality of a web site /portal, the more refined information can be made available to the user. Thus it becomes necessary to define quality and also determine the factors that measure the quality of web site. A quality factor should pin point to a particular aspect of the web site design. It is also important to define the kind of improvement that must be undertaken for improving quality of the web site from the point of view of a particular aspect. This paper is primarily focused on determining all important quality factors that can combined reflect the total quality as well as quality of a particular aspect of web site design. This paper also provides a base using which different kinds of improvements that should be made in order that the quality of the Web site will greatly be improved. Websites are part of our everyday life and are used to exchange and to convey information between user communities. Conveyed information comes in different types, languages and forms and incorporates text, images, sound, and video intended to inform, persuade, sell, present a viewpoint or even change an attitude or belief. Despite website proliferation, assessment of site quality remains a challenging area of research. Quality relates to customer satisfaction and also with the level of accomplishment of user expectation when interfacing a website.

Abstract: This study explored the interconnectedness between teachers understanding of Assembly Drawing and teaching of Assembly Drawing (AD) in the UThukela district of KwaZulu-Natal (KZN). Assembly drawing (AD) is an integral part of the Engineering Graphics Design (EGD) curriculum. AD is a universal graphical means of communication in the engineering field. AD requires learner to use spatial visualization skills when engaging in drawings, sectioning of machines, mental manipulation and rotation of objects in order to transform 2D images into 3D images. EGD learners have been repeatedly performing poorly in the AD section of the matriculation examination. Thus there is a need to establish the extent to which learners performance in AD results from the quality of teaching. Qualitative data was collected from 25 purposively selected EGD teachers using an open-ended questionnaire, focus group interviews, lesson plans, observations, and post observation interviews. The interconnectedness between teachers’ understanding of AD and their teaching of AD is revealed via our findings. The visual and spatial skills learners need to engage with AD were not foregrounded in teachers understanding of AD or their teaching of AD. Our findings elucidate teachers’ lack of pedagogical content knowledge pertaining to AD. It further points to the need to urgent continuous teacher professional development for practicing teachers if we are to overcome the challenges learners encounter with AD.

Abstract: ABSTRACT Mobile application can aid a student's learning process and comprehsion. However, the majority of these applications are designed without consideration for the needs and backgrounds of the Turkish student thereby often making the applications less effective or even redundant for this demographic. This paper proposes a solution to that problem by developing CEITech a mobile application in Turkish. CEITech is a user friendly-mobile application designed in Turkish to assist Turkish speaking students in learning multimedia development as a course. Although it is in the trial stage, CEITech is currently available on the Google Play Store and Apple Store and is being used by students in the Computer Education and Instructional Technology Near East University in Cyprus. Key words: CEITech, Mobile Application, Mobile Learning, App store, Multimedia, Education

Abstract: The pervasive distribution of online games gives new addictive things to children. Many children can spend hours of their time in front of their gadgets to access the games. It makes their social awareness decrease and become individualistic. Since, they do not need any friend to play the games. Amount to the negative impact of online games, there should be a development of traditional games. One of the potential traditional games to develop is kuda debog games. It can be deconstructed as Kuda Debog dance which symbolizes children�s happiness in playing �horse� made of banana stalk (debog). Kuda Debog is a traditional game which cannot be neglected, because it gives huge influence to children�s development of psychiatric, behavior, and social life. Based on those phenomenon, the problems discussed in this researcg is how is the form of Kuda Debog dance performance and how is the social development of children in Kuda Debog dance. This research used qualitative method with observation, interview, and documentation as the methods of collecting the data. The validity of the data was verified using triangulation. The methods of analyzing the data were domain analysis, taxonomy, and componential as well as the creation of themes to describe the meaning of the research focus. The result of the research shows the forms of the performance, including the drama, actors, movement, sounds, make up property, floor patterns, performing stage, and audiences.
