This study aims to suggest more efficient ways of teaching English more related to but distinct from major English, based on the needs and awareness of the students of English Education Department. For this, interviews and surveys have been carried out targeting some English Education majors. The results show that the satisfaction level of students is relatively low, marking around the score '3'. While the satisfaction level about classroom environment including the multi-media equipment, and professors' teaching ability, quality and methods is higher compared with other factors, the improvement of English skills and interest-causing levels are lower on average. Besides, this study also includes the surveys on the needs of students for various teaching programs, differentiated classes and qualified instructors. Based on the results, this study makes three suggestions as follows; (1) the opening of some specific English classes for English-education majors (2) the development of English-conversation classes related to English-education majors (3) the development of communication-centered English reading based on English literature.

As the 2015 revised curriculum is being implemented from 2018, efforts are being made to cultivate scientific literacy among students in the field of science. Scientific experiments help students to develop their interest in Science and their scientific attitudes. Learning through experimentation rather than learning scientific facts increases learners' understanding, and can be remembered longer. Therefore, experiments in Science subject are very important. However, in middle schools, scientific experiments are not performed due to the lack of time, budget and experimental material. In this research, we analyze middle school science textbooks, conduct questionnaires for students of science pre-service teachers, select the most important science experiments, and develop a mobile App to simulate and experience scientific experiments with the App. The proposed App is developed in a game format using quest-based learning methods to gain learning enhancement. It is also made using Unity. In this paper, after developing the app, we propose the direction of STEAM contents development through analyzing the difference from existing apps and the feedback from users.

By combining the elements of the game or game in education, it improves the interest of the students and improves academic achievement by creating an environment where they can participate directly. We propose a curriculum that can learn the core principles of the elementary curriculum through fusion. The proposed curriculum helps students to understand the principles of the elementary curriculum by learning the artificial intelligence method in board game form. Learning methods that incorporate such elements of the game will enable learners to learn the principles of IT so that they can develop their ability to understand objects from various perspectives and enhance their thinking skills. It is expected that the elementary artificial intelligence curriculum that incorporates the proposed gamification will contribute to the development of the information science curriculum, which has been highlighted recently from the 2015 curriculum.

The currently considered pyrotechnic separation nut is separated through the complicated process, because it has many internal moving parts and two variable-volume chambers connected by the vent hole. Therefore, it has many design parameters. Some of these are the contact angles between internal moving parts, the masses of the internal moving parts, the inner diameter of the push rod protrusion, the initial volumes of the chambers, the mass of the explosive charge, and the diameter of the vent hole. To improve the pyrotechnic separation nut, it is necessary to understand how the behavior of the separation nut is changed according to design parameters. In this point of view, parametric studies are carried out using the previously proposed prediction model for pyrotechnic separation nut behaviors. In each case, the parameter of the interest is changed while the others are kept unchanged. From the results, it is investigated how each design parameter influences the separation behavior.

This study was conducted to identify the using self-nail products for the purpose of developing indicators to respond to changes in nail industry due to the evolution of consumption patterns caused by the spread of self-nail culture. The final analysis of 293 survey was conducted on female adults living in South Gyeongsang Province from September 1, 2018 to October 30, 2018. The study found that women in their 20s were more interested in nail care than in most cases. The main route of obtaining nail-related product information was the higher the use of SNS as the age was younger(${\chi}^2=185.048$, p<.001). According to a survey of 165 people who have experience with self-nail products, 53.3 percent of 'paste stickers' were the most common, followed by 39.4 percent of 'paste nail tips' and 7.3 percent of 'home care products'. Looking at the disadvantages of self-nail products, between groups under their 50s and over 50s group saw a significant difference(${\chi}^2=27.032$, p=.008). For those in their 50s or younger, 'the inconvenience of daily life' was considered a disadvantage. On the other hand, people in their 50s and older considered 'short duration' as a disadvantage. The lower the age, the higher the willingness to use continuously(${\chi}^2=14.308$, p=.006).We found that there were differences in preference for self-nail products according to age. It was noticed that there were differences in satisfaction and persistence. This suggests the need for more specific follow-up studies on the use of self-nail products by age group. Therefore, this research aims to present basic data for the development of direction and custom program for the professional nail industry to advance, thus providing basic data to help the development of nail industry in South Gyeongsang Province.
