The U.S. education policy making and execution process, in which residents can directly participate as members of state or local boards of education, without entrusting a small number of experts to decide on issues of sharply intertwined political interests, can be presumed that it played a role in preventing conflicts and disputes that may arise due to differences of opinion or differences in the interpretation of laws and regulations between subjects. Such a consensus system in the United States suggests a supplementary point to the local education administration system in Korea, where conflicts between various educational entities are occurring because of the current excessive dependence on one superintendent of education.

To help students understand the deduction system in the proof, we analyzed the textbook on mathematics at first. As results, we could find that the textbook' system of deduction is similar with the Euclid' system of deduction. The starting point of deduction is different with each other. But the flow of deduction match with each other. Next, we searched for the example of circular argument and analyzed. As results, we classified the circular argument into two groups. The first is an internal circular argument which is a circular argument occurred in a theorem. The second is an external circular argument which is a circular argument occurred between many theorems. We could know that the flow of deduction system is consistent in internal-external dimension. Lastly, we proposed the desirable teaching direction to help students understand the deduction system in the proof.

The authors have been discussed the optimal voltage regulation method and on-line real time method using artificial neural networks in the distribution system interconnected with Distributed Generation and Storage(DSG) systems. However, these methods have difficulty in dealing with the random load variations and operation characteristics of a number of DSG systems. To overcome these problems, this paper shows the basic concepts of smart grid system which is considered as one of the power delivery system in the near future and presents an evaluation method on the impacts of customer voltages by the operation of smart grid system. The smart grid system can change the system configuration in a flexible manner by using the static switches and offer the different power qualities in power services through the power quality control centers.

Owing to pandemic (COVID-19), the traditional face-to-face education method has been changed to the non-face-to-face real-time online education methods. Using a real time-based video conference system, synchronous education can be adopted by face-to-face class easily. Specially, it is very important to minimize the difference in learning effects between face-to-face and non-face-to-face in Entrepreneurship education. In this study, in order to derive the factors that affect the satisfaction of learners in synchronous online education, authors collected data from learners taking a synchronous entrepreneurship course. Through previous research, learned the reality of education and the composition of lessons. Spatiotemporal effectiveness, mentor ability, and educational environment influence learning satisfaction. PLS-SEM results revealed that it was confirmed that only spatiotemporal effects affect learner satisfaction. However, the education environment (fluent operation and convenience of function use of real-time based online conference system) effect teaching presence, class structure, and spatiotemporal effects. Through this research, we hope to provide theoretical and practical support for developing effective teacher activities, proper lesson structure, convenient function of the conference system, and learner-centered online learning environment when developing synchronous online classes.

This study was implemented for the purpose of analyzing the effects of Engineering Education Accreditation. Now, 15 years has passed adopting the engineering education system. We need to analyze the effect that this system has changed on the ground of engineering education, and it cultivated the human resource. In order to achieve the purpose of this study, the survey were done on the professors, graduates, and workers. The results and conclusions of this study are summarized as follows: First, it is urgent need to change the system of accreditation, and to get the public trust on assessment. Second, it is necessary to make circumstance that engineering education accreditation is advertised to the industries, and the industry can join the development, consulting, evaluation of curriculum. Third, government needs to make the policy that gives the incentive to the industries, if they give some merits to the accreditation graduates. Fourth, certificate of program graduate is desired to spread the accreditation proliferation. Fifth, government should systemize that accreditation program can get advantage to be selected for the public finance business(e.g. BK, LINC).. It will impact the quality Improvement and accountability of engineering programs.

Recently the wireless internet technologies have been widely used in education environments. The purpose of this paper is to design and implement mobile class management support system. The proposed system is based on the existing CSCL theory and modified in accordance with mobile environments. The proposed system has the following characteristics. First, various types of cooperation are possible in this system. In this system, students can participate actively through tools such as BBS. Second, wired and wireless web sites are linked systematically so that users can access via either site. Two sites are complementary each other. Third, parents are encouraged to participate in class activities. Some basic information such as curriculum and daily announcement is open for parents. The proposed system has been applied to elementary school students. Extensive survey shows that the proposed system has good effect on participation, interaction, and satisfaction in class management, respectively.

The purpose of this study was to analyze the perception of a high school teacher on Admission Officer System. The subjects were limited to 324 high school teachers of Busan, Ulsan, and Gyeongsangnam-do regions. The major research question for the study was how are the perceptions of high school teachers about the Admission Officer System. The main results were as follows: first, high school teachers showed high understanding of the admissions overall. Second, high school teachers with counseling experience about applying to colleges considered the score of the College Scholastic Ability Test less important. Third, high school teachers have recognized that there is a distance between high school education activities and the Admission Officer System. Eliciting sympathy from the high school teachers for the Admission Officer System is a very important task. Negative perceptions of high school teachers on the Admission Officer System is still remained. The cooperation between leading universities and high schools would help the Admission Officer System work with its original purpose or goal.

Article 117, Paragraph 1 of the 「Constitution」 states that "Local governments may enact provisions relating to local autonomy, within the limit of Acts and subordinate statutes". It restricts the enactment of effective self-government laws. The fundamental problem-solving is securing the right to self-governing legislation through constitutional amendment. Therefore, it must be revised to "Local governments can make regulations on self-government to the extent that they handle resident welfare affairs in accordance with the subsidiarity and do not violate the law." In the long-term perspective, the current education council problem, which is contrary to the constitution, has to be revived as a constitutional independent education committee system, and the voting agency and the executive agency must go together and education councilors must have about 10 years of experience in education and education administration. The current superintendent's election system is of great significance in establishing democratic legitimacy by ensuring residents' right to vote and securing a superintendent's representation of residents. It hasn't been long since the system was implemented, but there are some side effects and it is argued that the election system should be replaced by the appointment by the head of the local government, the running mate system or the joint registration system. However it is thought that it is necessary to minimize and supplement the side effects rather than fixing the system as it violates the Constitution of the local education autonomy system.
