This study seeks to identify the reform of vocational education plans so as to bring about a seamless transition from school to work. It puts forward a number of suggestions based upon an analysis of vocational education policies in Korean and U.S. schools, concerning the government's role, partnerships between education and industry, the educational system, curriculum and work-based learning. First, not only government initiatives but also close partnerships between education and industry are essential to help vocational education in school the transition to employment. Education and industry should work closely together to standardize certificate related skills and to have these skills reflected in the curriculum. Also the government should strive to provide guidelines for work-based learning and formulate standards for supervision and evaluation. Second, to facilitate the school to work transition, comprehensive schools should be promoted so that students have access to a greater ranger of vocational education. At the same time, an assessment system that certifies a mastering of the basic skills of those who undergo the education should be introduced, and it should be related to earn these certificates. Third, standardized vocational skills should be included in the curriculum so that students can acquire skills that are useful for industry. All the students in vocational and general high schools should have access both to general education, the foundation for lifelong learning and for employ ability, and to basic occupational skills which empower students in dealing with rapid changes of technology. Also a range of specialized vocational curricula should be offered so that students can opt for more specialized occupations; and they can select careers appropriate to their capability. Fourth, so that all students to have the opportunity to take part in work-based education, which is closely related to employment, various work-based learning programs should be offered to meet the needs of students and their educational conditions. Companies should for their part train students thoroughly in accordance with the standards of work-based education. In addition, supervisors should be stationed both in schools and companies in order to administer the students' work-based learning.

Recently, the rapid development and development of the industrial environment has changed the talent that companies need. As the educational paradigm changes, the university education should complement the problems of the lecture education method (the existing knowledge transfer method) in order to cultivate the talents needed for the corporation. In order to improve self - directed and creative problem - solving ability, new teaching and learning methods are needed. In this study, we apply flip learning in the algorithm class which is an essential curriculum of computer engineering. This group is divided into groups that are combined with theoretical and practical lessons, and groups that have applied theoretical lessons by applying flip learning, and groups that employ traditional lecture techniques. To improve learner's learning motivation and academic achievement, we propose a flip learning teaching method suitable for the algorithm subject and apply it directly to the class. Based on the results, we compare and analyze the academic achievement and learning satisfaction of learners.

The rainwater pumping station located near a river prevents river overflow and flood damages by operating several pumps according to the appropriate rules against the reservoir. At the present time, almost all of rainwater pumping stations employ pumping policies based on the simple rules depending only on the water level of reservoir. The ongoing climate change caused by global warming makes it increasingly difficult to predict the amount of rainfall. Therefore, it is difficult to cope with changes in the water level of reservoirs through the simple pumping policy. In this paper, we propose a pump operating method based on deep reinforcement learning which has the ability to select the appropriate number of operating pumps to keep the reservoir to the proper water level using the information of the amount of rainfall, the water volume and current water level of the reservoir. In order to evaluate the performance of the proposed method, the simulations are performed using Storm Water Management Model(SWMM), a dynamic rainfall-runoff-routing simulation model, and the performance of the method is compared with that of a pumping policy being in use in the field.

The main idea of this paper is to combine position information in sentence and query type classification to make the documents ranking to query more accessible. First, the use of conceptual graphs for the representation of document contents In information retrieval is discussed. The method is based on well-known strategies of text comparison, such as Dice Coefficient, with position-based weighted term. Second, we introduce a method for learning query type classification that improves the ability to retrieve answers to questions from Question Answering system. Proposed methods employ naive bayes classification in machine learning fields. And, we used a collection of approximately 30,000 question-answer pairs for training, obtained from Frequently Asked Question(FAQ) files on various subjects. The evaluation on a set of queries from international TREC-9 question answering track shows that the method with machine learning outperforms the underline other systems in TREC-9 (0.29 for mean reciprocal rank and 55.1% for precision).

Many industrial servo amplifiers employ power transister as output device. Thyristor converters are not adopted to drive servo motor, although thyristor is superior to power TR in power rating, noise immunity, price, and size. The reason is, thyristor has no ability of self turn - off. Here in this paper line commutation, in which thyristor is turned off naturally since cathode voltage is higher than anode as time goes by, is employed to turn on thyristor with a delicate sequence. We developed thyristor servo amplifier which does not cause any damage on thyristor because it is designed to prevent triggering the two SCRs in the same arm simultaneously. And it was made clearly how to trigger SCR without any power line shorting and also harmonic analysis is carried out with the aid of FFT analyzer and proved that it can be used even severe reactive load. The designed circuit operated as a good DC amplifier in conventinal servomotor and the results can be use as a position control system application.
