This thesis examined the main revolution trend of Chinese engineering education system which is closely related to the demand of the industrial world. The reasons for which China tried to revolutionize engineering education were as follows ; firstly, the lack of high-qualified and professionalized man power in the industrial world. Secondly, the rupture in the age structure and thirdly, graduate students' insufficient ability to adapt to the industrial companies. These situation had been influenced by professional education after the fashion of the Soviet Union and the Cultural Revolution. Thus, since 1980s, government have extended man power supply through various ways and maintained equilibrium between supply and demand within the industrial world. Also, government began to retrian the existing engineers, magnify the regular number in college students of science and engineering and treat an experienced man favorably in graduate schools. The State Education Commission leaded in searching for the ways to train engineers and testing the master of engineering training system. As an essay at reform, many attempts will be tried ; bringing-up excellent students, the system of multi-degrees, field work, bachelor-master integration management, the system of master and doctor by thesis, strengthening educational-industrial cooperation, experimental school, adult school, and local school. Until 21c to come, this trend will be accelerated on.

With the emergence of lifelong learning society and the decrease in school-age population, structural changes of universities are lead to an adult-friendly university system reform. Since 2008, university-based lifelong education activation projects, such as the lifelong learning-centered university cultivation project and the lifelong learning college project have been accelerated as a university lifelong education system support project that integrated both projects in 2015. This study analyzed the present status of university lifelong education system support project management, according to four analysis frameworks; adult-friendly curriculum, adult learner support system, evaluation of diverse learning performances, and empowerment of adult learners, based on adults' learning desire for higher education in a lifelong learning society. University lifelong education system reform suggests to aim at promotion of empowered adult learners, who give themselves positions and roles, through cultural adaptation and integration between generations.

Recent advances in the 4th Industrial Revolution have accelerated the change of the working environment, such that the paradigm of education has been shifted in accordance with career education including the free semester system and the high school credit system. While the purpose of those systems is students' self-motivated career exploration, educational limitations for teachers and students exist due to the rapid change of the information on education. Also, education technology research to tackle these limitations is relatively insufficient. To this end, this study first defines three requirements that education technologies for the career education system should consider. Then, through data-driven artificial intelligence technology, this study proposes a data system and an artificial intelligence recommendation model that incorporates the topics for career exploration, courses, and majors in one scheme. Finally, this study demonstrates that the set-based artificial intelligence model shows satisfactory performances on recommending career education contents such as courses and majors, and further confirms that the actual application of this system in the educational field is acceptable.

Society and science digital textbooks were developed in 2014. That have been using in some elementary and middle school. But some people worry about the internet addiction of student accelerated by using digital textbook. However I didn't agree that, because studies about that had not been performed enough. So I analyzed effect of internet addiction by using digital textbook. As a result, Internet addicted students at class to be not using digital textbook are twice as many as Internet addicted students at class to be using digital textbook. But the difference between two groups do not means according to cross analysis. Therefore, I can't conclude that using digital textbook have an adverse effect on internet addiction.

Over the past decade, driven by advances in educational theory and pressures for efficiency in the clinical environment, there has been a shift in surgical education and training towards enhanced simulation training. Microsurgery is a technical skill with a steep competency learning curve on which the clinical outcome greatly depends. This paper investigates the evidence for educational and training interventions of traditional microsurgical skills courses in order to establish the best evidence practice in education and training and curriculum design. A systematic review of MEDLINE, EMBASE, and PubMed databases was performed to identify randomized control trials looking at educational and training interventions that objectively improved microsurgical skill acquisition, and these were critically appraised using the BestBETs group methodology. The databases search yielded 1,148, 1,460, and 2,277 citations respectively. These were then further limited to randomized controlled trials from which abstract reviews reduced the number to 5 relevant randomised controlled clinical trials. The best evidence supported a laboratory based low fidelity model microsurgical skills curriculum. There was strong evidence that technical skills acquired on low fidelity models transfers to improved performance on higher fidelity human cadaver models and that self directed practice leads to improved technical performance. Although there is significant paucity in the literature to support current microsurgical education and training practices, simulated training on low fidelity models in microsurgery is an effective intervention that leads to acquisition of transferable skills and improved technical performance. Further research to identify educational interventions associated with accelerated skill acquisition is required.

The president of the country has a very significant political role, but the study of the history about the presidency has not really been emphasized. This study is to examine how to apply the online contents about presidential history to elementary education. The documentaries presented in elementary social studies have a great effect on elementary students because their cognitive development is accelerated by understanding modern Korean history along with the presidential history and political issues through historical records. Therefore, this study focuses on investigating the method of application of the presidential history by having the presidential historian build online contents and provide this information to teachers and students.

The deblocking filter (DF) reduces blocking artifacts in encoded video sequences, and thereby significantly improves the subjective and objective quality of videos. Statistics show that the DF accounts for 5-18% of the total decoding time in high-efficiency video coding. Therefore, speeding up the DF will improve codec performance, especially for the decoder. In view of the rapid development of multicore technology, we propose a parallel DF scheme based on a modified order of accessing the coding tree units (CTUs) by analyzing the data dependencies between adjacent CTUs. This enables the DF to run in parallel, providing accelerated performance and more flexibility in the degree of parallelism, as well as finer parallel granularity. We additionally solve the problems of variable privatization and thread synchronization in the parallelization of the DF. Finally, the DF module is parallelized based on the HM16.1 reference software using OpenMP technology. The acceleration performance is experimentally tested under various numbers of cores, and the results show that the proposed scheme is very effective at speeding up the DF.

In order to examine the effect of humidity on hydrogen embrittlement of STS 444 weld zone for boiler with dry and wet welding conditions, this paper was carried out the accelerated hydrogen osmosis test and the electrochemical Tafel polarization test. In 0.5M $H_2SO_4$ + 0.01M $As_20_3$ solution, this test is added to load of $1400kg/cm^2$ together with hydrogen osmosis by current of $50 {mA/cm^2}$ for 60 min.. The electrochemical Tafel polarization test was carried out in 0.5M $H_2SO_4$ + 0.01M $As_20_3$ solution. Therefore, the effect of humidity on hydrogen embrittlement of STS 444 was considered. The main results are as following: On the basis of hydrogen embrittlement mechanism, that is, integrated electrochemical polarization characteristics with the established mechanism of hydrogen embrittlement, the reduction rate of corrosion current density of weld zone in the wet weld condition is larger than in the dry condition. We can nondestructively predict the degree of hydrogen embrittlement of STS 444 weld zone for boiler through the reduction rate of electrochemical corrosion current density.
