Telexistence is fundamentally a concept named for the technology that enables a human being to have a real-time sensation of being at a place other than where he or she actually is, and to interact with the remote environment, which may be real, virtual, or a combination of both. It also refers to an advanced type of teleoperation system that enables an operator at the controls to perform remote tasks dexterously with the feeling of existing in a surrogate robot. Although conventional telexistence systems provide an operator the real-time sensation of being in a remote environment, persons in the remote environment have only the sensation that a surrogate robot is present, not the operator. Mutual telexistence aims to solve this problem so that the existence of the operator is apparent to persons in the remote environment by providing mutual sensations of presence. This paper proposes a method of mutual telexistence using projection technology with retro-reflective objects, and describes experimental hardware constructed to demonstrate the feasibility of the proposed method.

The real-time system is now used on many fields, such as telecommunication, military, information system, evenmedical to get information quickly, on time and accurate. Needless to say, a real-time system will always considerthe performance time. In our application, we define the time target/deadline, so that the system should execute thewhole tasks under predefined deadline. However, if the system failed to finish the tasks, it will lead to fatal failure.In other words, if the system cannot be executed on time, it will affect the subsequent tasks. In this paper, wepropose a real-time system for sending data to find effectiveness and efficiency. Sending data process will beconstructed in MATLAB and sending data process has a time target as when data will send.

Developing a microcontroller-based system for controlling the flywheel motor of high-dynamics spacecraft using Russian-made parts and components made it possible to make statement of the problem of searching control function for a preset rotation rate of the flywheel rotor. This paper discusses one of the possible options for mathematical study of the stated problem, namely, application of structural analysis based on graph theory. Within the framework of the stated problem a graph was constructed for generating the new required rate, while in order to consider the stochastic case option the incidence and adjacency matrices were constructed. The stated problem was solved using a power matrix which transforms a set of contiguous matrices of the graph of admissible solution edge sequences, the real-time control function was found. Based on the results of this work, operational trials were run for the developed control function of the flywheel motor rotor rotation rate, a math model was constructed for the real-time control function, and conclusions were drawn about the feasibility of implementing the results of this study. Key words: Control function, graph, incidence matrix, adjacency matrix, power matrix, microcontroller control of the flywheel motor, highly dynamic spacecraft.

The paper is titled, "Becoming True Learners in a New Era of Globalization." This title is important for two reasons. First, internal cause, that is the tendency in society where people only attach importance to degree, certificate or diploma, not science or competence. Second, external cause, that is arising from the digital revolution that gave rise to global competition, where everyone was expected to become true learners. Otherwise, he will be marginalized, as a human being, which according to Michael Fullan, is not feasible, morally, socially, and economically. True learners, as James R. Davis and Adelaide B. Davis point out, refer to people who love new things, new thinking, and new skills. He learned not only to know (learning toknow), but more than that to think (learning to think) and solve (learning to solve) the problem. Human learners try to learn and develop knowledge not only from college, formal learning, and from the text book, but from experiences and from the real world or reality of life. True learners have 5 (five) prominent characters. First, they have a high curiosity that makes them passionate and studying diligently. Second, they like to share knowledge and experience to others. Third, they like to develop and expand knowledge. Fourth, they have contributions to the progress of culture, civilization, and humanity. Fifth, they have a humbleattitude and the open to thoughts of others. The new century, globalization, requires a new man, a true learner.

Introduction: Infection with HPV is the main cause of cervical cancer. Determining HPV infection and the types of HPV plays an important role in diagnosis, treatment and prognosis of cervicitis/cervical cancer. Aims: Determining proportion of high-risk HPV types and the occurrence of coinfection with multiple HPV types. Methods: 177 women with cervicitis or abnormal Pap smear result were enrolled in the study. Performing the real-time PCR for detecting HPV and the reverse DOT-BLOT assay for determining type of HPV in cases of positive PCR. Results: 7 types of high-risk HPV was dectected, the majority of these types were HPV type 18 (74.6%) and HPV type 16 (37.6%); the proportion of infection with only one type of HPV was 30.4% and coinfection with multiple HPV types was higher (69.6%), the coinfected cases with 2 and 3 types were dominated (32.2% and 20.3%, respectively) and the coinfected cases with 4 and 5 types were rare. Conclusion: Use of the real-time PCR and reverse DOT-BLOT assay can determine the high-risk HPV types and the occurrence of coinfection with multiple HPV types. Key words: HPV type, Reverse DOT-BLOT, real-time PCR,PCR, cervical cancer
