Trains running through urban railroad sections in large cities are an important means of transportation for many passengers. In 2019, the number of passengers using the Seoul Metropolitan Railway reached 2.9 billion. The drivers are responsible for the safe operation of the numerous passengers repeatedly go two to three minutes apart, looking only at the railroad tracks in the dark underground section. Although the urban railway system is becoming state-of-the-art and accidents are caused by system errors and human error continue, so the train driv-ers must exert a high level of concentration to prevent accidents. This professional nature has led to considerable job stress for drivers, and the annual subway accident is feared to cause depression, bipolar disorder, obsessive compulsive disorder, and various mental disorders and panic disorder caused by post-traumatic stress disorder. In this paper, while the accident lessons and measures are active in railway operation institutions after the occur-rence of various railway accidents, the measures for drivers have been taken away from the very insufficient exist-ing methods and considered the engineer as a special class of high-risk groups, and the application of the psycho-logical stability program of firefighting officials, who are currently high-risk. The meaning and necessity of devel-oping human psychological stability program for railroad engineers were presented by analyzing these.

Foreign plants introduced by overseas exchanges are rapidly transformed into naturalized plants and pose se-rious threats to biodiversity, including domestic native species. Therefore, this study is based on the flora survey data of 776 map numbers(1200 places) for 12 years from 2006 to 2017, the third to fourth data of the National Natural Environment Survey, the nation’s largest basic research project on the natural ecosystem. By analyzing plant species and naturalized plant species and predicting naturalized plant species and naturalization Index, they can be used as basic data to study environmental changes, or they can be used to set various indicators ap-plying naturalized plants and naturalization Index and to set the upper limit of permit for development activities. Therefore, in this study, one-way ANOVA analysis and MANOVA analysis were conducted to determine whether there is a difference in naturalized plant species and naturalization Index by year, region, altitude, population density, GDP, and the ratio of forest to area. There was a correlation between the items such as year, region, alti-tude, population density, GDP, the ratio of forest to area and the number and naturalization Index of naturalized plants, and the greatest impact on the naturalized plant species and naturalization Index. Curve estimation re-gression, multiple regression, and dummy variable regression were performed to find out which items are causing the problem. Through this research, it is thought that the naturalization Index predicted by this study can be used for the issue of Permit on Exclusive use of inter-mountain area altitude standard, which is operated under the Act on Planning, and Use of National Territory, and the Mountain Site Management Act. The naturalization Index predicted by this study can be used as basic data for setting the upper limit of Permit on Exclusive use of inter-mountain area, or for studying environmental change, or for setting various indicators.

Purpose; The purpose of this study is to examine the problems of the traditional teaching method, and to clari-fy how the teaching and learning methods for creative talents is reflected through the design on teaching and learning method for creative talent in the age of artificial intelligence(AI). The design of the creative teaching and learning model proposed in this study is largely classified into two stages, In-class(Offline Practice Learning Steps) and After-class(Post-Class Inquiry and Project-Based Learning). And the mechanism that connects learning states organically rather than independently separate concept, but is analyzed based on a questionnaire evaluation on the concentration and immersion of classes and the understanding of creative teaching and learning methods. And this paper explores that learners who will be at the center of future society have the power to think through concentration and immersion in solving their own difficult problems based on their experience of teaching and learning methods in university education. In this process, creativity is expressed. They will also feel happy with a sense of accomplishment, confidence, and satisfaction while solving difficult problems. This is why problem-based learning is necessary in university education. The teaching and learning method proposed in this study is to in-duce learners to think freely based on dialogue rather than discussion, and to lead the class by achieving the con-centration and immersion in class, thus leading to a sense of achievement. The teaching-learning model, which incorporates elements that can solve problems on their own with convergent and logical thinking, has become an opportunity to reveal the importance of fostering creative talent for the artificial intelligence era.
