Recent measurement studies of real teletraffic data in modern telecommunication networks have shown that self-similar (or fractal) processes may provide better models of teletraffic in modern telecommunication networks than Poisson processes. If this is not taken into account, it can lead to inaccurate conclusions about performance of telecommunication networks. Thus, an important requirement for conducting simulation studies of telecommunication networks is the ability to generate long synthetic stochastic self-similar sequences. A new generator of pseu-do-random self-similar sequences, based on the fractional Gaussian nois and a wavelet transform, is proposed and analysed in this paper. Specifically, this generator uses Daubechies wavelets. The motivation behind this selection of wavelets is that Daubechies wavelets lead to more accurate results by better matching the self-similar structure of long range dependent processes, than other types of wavelets. The statistical accuracy and time required to produce sequences of a given (long) length are experimentally studied. This generator shows a high level of accuracy of the output data (in the sense of the Hurst parameter) and is fast. Its theoretical algorithmic complexity is 0(n).

The purpose of this article is to examine the dynamics of pension insurance policy-making and policy outputs under the developmental state of Korea, by analysing the first attempt to establish the national pension scheme in the early 1970s. To the aim, this article formulated the comprehensive analytical framework from the viewpoint of process-oriented perspective, linking policy-making dynamics with the policy context as an external constraint and policy output as a result of policy-making. Policy context was explored in terms of three variables of politics, civil society and economy, whilst policy-making and policy network dynamics were examined by employing the following variables: i) initiators, motivation and triggering devices, ii) number of participants and key players, iii) participants' interests, iv) major conflicting parties and key differences of allegation, and v) interactions between participants. Policy outputs were analysed by looking into the mainly reflected interests and the change of intended policies.

Purpose: The purpose of this study was to investigate the effect of oral health education on adolescents. Methods: The subjects were middle school students in a health promoting school in Gunpo, Gyeonggi Province. Before giving the students oral health instruction, their modified Patient Hygiene Performance index (PHP index) was measured using disclosing solution. Then, the students were taught the right way to brush teeth (Rolling method) and use oral hygiene devices such as dental floss, tongue cleaner and interdental brush. Their modified PHP index was re-measured three days after and seven days after the education to evaluate the effect and persistency of oral health education. of the total 116 students, 48 students who completely filled out the questionnaire and participated in the whole process, photo shooting and three times of PHP index measurement, were included in the final analysis. Results: The students' modified PHP index significantly decreased three days after the education. However, the index slightly went back up seven days after the oral health education. Conclusion: Oral health education was effective in reducing dental plaque which remained after brushing. Continuous education about and constant motivation for oral hygiene turned out to be critical to maintain the impact of oral health education. Therefore, it is necessary to develop educational contents which can constantly motivate teenagers.

Currently, information society is rapidly changing and demands innovation and creativity in various fields. Therefore, the importance of mathematics, which can be the basis of creativity and logic, is emphasized. The purpose of this paper is to develop a math education application that can further expand the logical thinking of mathematics and allow voluntary learning to occur through the use of readily available teaching aid for children to form motivation and interest in learning. This paper provides math education applications using a smartphone and blocks for children. The main function of the application is to shoot with the camera and show the calculated values. When a child uses a block to make a formula and shoots a block using a camera, you can directly see the calculated value of your formula. The preprocessing process, text extraction, and character recognition of the photographed images have been implemented using OpenCV libraries and Tesseract-OCR libraries.

This study surveyed 255 college students enrolled in beauty contract departments located in Seoul(5 schools) and Gyeonggido(6 schools) to investigate their admission support procedure and educational satisfaction. The study found as follows; Data collection was performed from March 25 to May 30, 2018 using SPSS WIN 21.0 for their statistical processing. With respect to data analysis, first, frequency analysis was conducted to look at the general characteristics of the subjects. Second, the admission support procedure of beauty contract department was investigated and cross analysis was performed to see if there was any change according to the subjects' general characteristics. As a result of looking at the awareness on department, 89% were found to be aware of the contract department system. As for their motivation to applying for the department, the largest reasons were found to obtain a degree and to become a hair designer within a short period of time. The most frequent route of application was a recommendation by their high school teachers. The highest priority consideration in choosing a department was the brand awareness of an associated industrial entity. With respect to the complementation education in curriculum, practical technique related to the major was found the highest. 66.7% said they would recommend the department when it comes to the intention to recommend the department. 24.0% were found satisfied with the education regarding educational satisfaction. Therefore, in order to improve the educational satisfaction of the contract department, it is necessary to acquire knowledge of the field technique and practical salon education.

Site-specific performance is always the real on-site work taking place at the site. Hence, it deals with the reality, in other words, the time of creation and formation. And it creates value and meaning through the interaction and continuous direct communication process between the performers, audience and the local residents. In this performance, the audience's status as the passive observer changes. They become the co-agent who actively lead and complete the performance through their own experience. We have examined the The Working Methods of Site-specific Performance and Aesthetics of Effect through four Korean performances ; Marie, An aesthetic experiment of site as the storyteller; Heterotopia and Urban Movement Research or Play: We Will Move Your Sofa, as performances which have Revealed history, politics, institution engraved in the site ; A Song of Mandala and Miracle, as a ritualistic site-specific performance at the historic site. Some remarks on Site-specific performance ; First, In Site-specific performance, the habitus peculiar to the stage art and the mode of reception are changed. Second, a new mode of theatrical communication requires creator and audience to have a sharp aesthetic sensibility and to change one's perceptual habit. Third, Site-specific performance can act as a demonstration for the viewpoints of political activism through what could be called a dramatic close-up effect. Fourth, Site-specific performance also has the risk of merely becoming an unfocused and scattered performance or degenerating into a pseudo-sightseeing. To avoid this, an in-depth study of the site and its socio-cultural context, and the clear motivation with which one is trying to reveal and tell from the site must be indispensable. As the co-agent, the audience should also be aware and think about what the given performance signifies today.

This study suggests the ways to promote the technology startups founded by professor, who differs from student or researcher in social status, risk-taking tendency, and motivation. Literatures were reviewed to understand the advantage of faculty's tech start-up, foreign cases, and related researches. In addition, key stakeholders were interviewed. The study shows that domestic faculty entrepreneurship is currently in infant stage while facing obstacles in institutional, financial and practical aspects. In order to promote faculty entrepreneurship, the study suggests that university and professor set up the benefit sharing structure in advance, that the public sector establishes a holding company or investment fund dedicated to support a faculty startup, that proactive effort be made to attract passive professors to the startup world, and that private companies join faculty startups in the process of concept proofing and product commercialization. The study is expected to provide government, university, and industry with practical implication in promoting faculty startup.

The fourth industrial revolution era calls for the ability to solve problems creatively based on basic literacy for technology. These capabilities can be enhanced through the maker education linked to SW education STEM convergence education. Meanwhile, one of the tasks that must be set prior to the maker education is to take an educational approach rather than a tech-centric approach and consider ways to stimulate interest and motivation of the participants. For this purpose, this study developed and applied an engineering-oriented Reading & Maker education program to prospective teachers so that they could participate in active making activities on their own with interest and sympathy rather than simply guiding maker activities. As a result of the study, the results of the maker education recognition survey after the application of the program showed a statistically significant improvement(p<.000).
