The Internet activities promote learners＇ self-monitoring ability, encourage the use of multimedia and network technology, and develop students＇ cooperation and participation. During the latest years, there have been many changes in education as these new technologies, including VLEs （Virtual Learning Environments）, which have become an important part in the teaching/learning process. According to Tech Terms Computer Dictionary （2012）, VLE is a virtual classroom where teachers and students communicate. VLEs have evolved as at an early stage, they were only ways of transmitting information： Teachers uploaded the multimedia resources and students read this information. At a higher stage, VLEs have become interactive. This means that students become active. We have designed a virtual environment where students, weekly, must contribute their opinions and comments in response to a required activity uploaded by the teacher. In this paper, we describe this weekly task and analyze students＇ opinion about this planned activity. The students become an active subject in this field. In this paper, we show how VLEs are no longer a means of transmitting information but a means of interaction as well as a way of motivating our students to be involved in their learning process展开更多

Therefore, the Finnish Defence Forces will also need professional and motivated individuals both now and in the future. The variable, interdependent, and complex environment has set totally new requirements for future＇s officers1. The Finnish cadets＇ selection process plays a crucial role, because the Finnish Defence Forces educate and train all the officers by itself. By means of the student selection will be made decisions whose influences have long temporal dimension, The officers who graduate from the Finnish National Defence University will build up the tomorrow＇s Finnish Defense Forces. In this paper, it will address the quality and functionality of the Finnish Defence University＇s student selection processes as part of competence and knowledge management from the organization＇s point of view2. Because of overall changes of society and the security environment, the Finnish officers＇ education and training system （see Figure 1） has been modified frequently during the few recent years. Both the reforms of the degree programs of Military Science and the Finnish higher education culture＇s modifications have been tried to notice during the analysis. The paper is based on the author＇s doctoral thesis that is compiling at the moment.展开更多

It isproceed that this algorithm solves 2-SAT and Horn-SAT in linear time and k-positiveSAT (in which every clause contains at most k positive literals) ill time O(F.),where F is the length of input F, n is the number of atoms occurring in F, and k isthe greatest real number satisfying the equation x = 2-. Compared with previousresults, this nontrivial upper bound on time complexity could only be obtained fork-SAT, which is a subproblem of k-positive SAT.展开更多
