A concept test was administered to college students and teachers to identify their understanding of chemical equilibrium and equilibrium shift. The subjects were 53 freshmen in the General Chemistry class, 28 juniors in the Physical Chemistry class and 26 seniors from a university and 10 high school teachers in Seoul. Test items include the calculations of partial pressure and concentration of the gas in the mixture, the equilibrium constant cal-culation and the prediction of equilibrium shift when an inert gas is added to the gaseous reaction system, and the equilibrium concentration calculation and the prediction of equilibrium shift when water or common ion is added to the weak acid solution. The test was focused to identify whether the subjects can predict equilibrium shift using the reaction quotient change for the situations in which Le Chatelier principle is difficult to apply. The results showed that the achievements of teachers and juniors were significantly higher than those of freshmen and seniors. Many stu-dents had difficulties in predicting equilibrium shift using the reaction quotient while they could calculate partial pres-sure and concentration for the same situation. It means they are lack of conceptual understanding of chemical equilibrium shift.

AI technology has developed in the form of decision support technology in law, patent, finance and national defense and is applied to disease diagnosis and legal judgment. To search real-time information with Deep Learning, Big data Analysis and Deep Learning Algorithm are required. In this paper, we try to predict the entrance rate to high-ranking universities using a Deep Learning model, RNN(Recurrent Neural Network). First, we analyzed the current status of private academies in administrative districts and the number of students by age in administrative districts, and established a socially accepted hypothesis that students residing in areas with a high educational fever have a high rate of enrollment in high-ranking universities. This is to verify based on the data analyzed using the predicted hypothesis and the government's public data. The predictive model uses data from 2015 to 2017 to learn to predict the top enrollment rate, and the trained model predicts the top enrollment rate in 2018. A prediction experiment was performed using RNN, a Deep Learning model, for the high-ranking enrollment rate in the special education zone. In this paper, we define the correlation between the high-ranking enrollment rate by analyzing the household income and the participation rate of private education about the current status of private institutes in regions with high education fever and the effect on the number of students by age.

The National Competency Standard (NCS) is being implemented on the basis of a college of higher education. The college offers intensive education by organizing three areas of knowledge, skills and attitudes so that students can perform their full capacity at the same time as graduating in industrial field. Health Department at the College has been training for a variety of medical personnel, including medical technician regions. Especially, the medical technician and medical sector must be licensed to work in the medical field. Therefore, passing the national examination license is a prerequisite for employment. In this study, the health law scores of the third grade students (about 200 students) of the radiology department of D College were analyzed at weekly intervals. The weekly score acquisition can be predict the pattern of student class achievement of individual students. Furthermore, these results can predict the possibility of passing the radiation license examination for individual students.

This research attempted to identify the factors associated with the intention of human papilloma virus vaccination among mothers of elementary school daughters. The subject of study is 132 mothers of elementary school students. Data collection was conducted from July 1 to August 30 in 2017, and analyzed using SPSS 23.0 Program. Results showed that 94.7% children of the participants had not been vaccinated, whose reasons were the low knowledge about HPV vaccination, concerns about its side effects, burden for cost. The attitude toward HPV vaccination appeared to be the most important predictor of vaccination, which was followed by perceived behavior control and subjective norm as meaningful predictors, as well. Based on these results, further researches should be conducted to develop educational programs, which are able to offer exact information about the effect and side effect of HPV vaccination, and verify the effectiveness.

Collaborative filtering is a method to predict preference items of a user based on the evaluations of items provided by others with similar preferences. Collaborative filtering helps general people make smart decisions in today's information society where information can be easily accumulated and analyzed. We designed, implemented, and evaluated a course recommendation system experimentally. This system can help university students choose courses they prefer to. Firstly, the system needs to collect the course preferences from students and store in a database. Users showing similar preference patterns are considered into similar groups. We use Pearson correlation as a similarity measure. We select K-nearest students to predict the unknown preferences of the student and provide a ranked list of courses based on the course preferences of K-nearest students. We evaluated the accuracy of the recommendation by computing the mean absolute errors of predictions using a survey on the course preferences of students.

In this paper, the researchers investigated the influence of graphing calculator in learning the concept of linear function for the gifted students. Elementary students who were taking a course in enrichment mathematics at Science Education Institute for the Gifted in Mokpo National University were selected for this study. The researchers analyzed students' processes of mathematical inference and conjecture, and students' algebraic description. We found the facts that the visualization using a graphing calculator and CBL is helpful to the gifted students in understanding concepts of liner function, finding the relationship between variables, analyzing and presupposing of graph. But, using graphing calculator can be a factor that disturbs learning of students who have too much of curiosity on graphing calculator.

This study was conducted to raise awareness of careers in the Department of Library and Information Science (LIS) as well as to investigate current awareness and preferences for LIS Department as a strategy to cope with the rapidly changing university environment. To do this, a survey of high school students was carried out, with results as follows: First, awareness about the LIS Department and awareness about librarians in our country's high school students was very low. Second, for possible careers in LIS Department, students responded that a graduate of LIS department was likely to enter the workplace in public libraries, state libraries, university libraries, or school libraries, but they would like to work at broadcasting library, national libraries, school libraries, university libraries, public libraries, or portals. Third, awareness of the career path for the LIS Department showed a very large impact on a preference for the LIS Department. Therefore, students who have heard about the LIS Department are highly probable to select this department when they reach university.
