The purpose of this study is to re-concept the future battle of the Army, which combines the effects of advanced technology on the concept of combat and the AICBM technology. The "war concept" changes with the times, and can be seen through the following two examples. First, it is a concept that achieves relative superiority by analyzing enemies. A case in point is the U.S. military's development of a "public joint battle" into a "multi-domain operation." Second, it is 'science and technology' that leads to a change in the concept of combat. A case in point is that the firepower warfare on land and sea in World War I developed from World War II to "air warfare" due to the emergence of aircraft. In this regard, the U.S. military is focusing on the concept of fighting in line with the future operational environment based on high-tech science and technology and the construction of the future military through the creation of the "Future Command." Therefore, our military needs to utilize the major technologies of the fourth industrial revolution as an opportunity to develop the concept of future combat, and the future war will greatly affect the development of the concept of advanced science and technology carrying out war, as AIC technology based on the fourth industrial revolution will promote innovation in defense operations in the form of super-connected, super-intelligence and super-integration. Therefore, this study will present the impact of advanced technology on the concept of combat and the concept of battle of the future Army incorporating the technology of AICBM.

The purpose of this study is to explore some directions and alternatives for reforming the school education system, which is one of the core policy agendas of the Korean society that has met the upcoming 4th industrial revolution era and intelligence information society. Korean school education is a supplier-oriented system that does not take into consideration student's individual needs and aptitudes, and maintains uniform educational and learning practices while strengthening the characteristics of factory school model of the early 20th century. Especially, according to the excessive follow-up of the college entrance examination of the people the de-contextualization of knowledge and the instrumentation and learning of the education has been deepened. For the reform of the education system, first, it should transform the curriculum delegation system from the current administrative to teacher-based system. Second, we need to dismantle the bureaucratic corps of teacher that erodes the autonomy of the teacher and should establish the professional teacher system. Third, we should overcome egoism of each curriculum territory and reform the teacher education system. Fourth, it is necessary to overhaul the system of education and administrative bureaucracy as well as to overhaul the system of educational law. Fifth, it is necessary for the school administration to provide more effective communication between learners and teachers.

Given that nowadays things get very fast due to the pervasive use of the Internet and mobile devices, decision-making time can be an important variable in the online economic decisions. Although in experimental and behavioral economics, measures like scores or earnings are usually preferred, this study argues that the time variable can be dealt with as a new decision outcome. Thus, by selecting some psychological factors presumably impactful in the online context (i.e., incidental emotions, psychological distances, and individual's impulsivity), this study tested their effect on decision time in the online centipede game. As a result, the mean decision time in the game was longer (1) in the happiness condition than in the anger condition and (2) in the friend condition than in the stranger condition. The people with attention difficulties spent a short time in the decision and the people who dislike complex problems spent a short time in explaining their decision. This study can contribute to the field as it used the decision time as the dependent variable and it tested the effect of psychological factors in the context of online decision-making. Future studies can be conducted in other online decision situations or by considering other psychological variables.

'Beauty and the Beast' was generated as a novel in 1740 and descended to date with the musical movie in 2017. This study is to understand what contents has been derived and expanded from one story for 277 years upon analyzing 'Beauty and the Beast' with the background of the times. Due to the limitation to include all the folktales and stories, the subjects of this study are limited with the contents that had been known and recorded as 'Beauty and the Beast.' 'Beauty and the Beast' has been expanded to 7 types of contents including novel, fairytale, movie, drama, animation, musical and film opera. It was created as a novel in the eighteenth century, made as a fairytale, and developed as a movie by Jean Cocteau, a movie director. With Industrial Revolution and the development of science, 'Beauty and the Beast' which derived into animation, drama, and musical contents, has been developed as the film opera thanks to the new trial of Philip Glass and the development of music industry. 'Beauty and the Beast' is still regenerating with a variety of contents continuously upon the development of computer technology and the fad of global remake. With anticipation of further analytical studies on 'Beauty and the Beast,' it is expected that the data of this study can be contributed as a reference in the other studies.

NLP means the technology that mechanically analyzes a language spoken by a human and makes it into a form that can be understood by a computer. This is important because it is a core technology for communication between humans and devices, which is the basis of artificial intelligence. In this paper, I analyzed patent information of US and Korea in order to identify technical trends related to NLP, especially semantic analysis. and the purpose of this study is to provide meaningful information for future research on NLP. In conclusion, the number of Korea patents is 7.9% compared to the USA and the different frequencies of the major keywords were found to differ from country to country in technical direction. In addition, the upward or downward keywords are twice as many in the U.S. as in Korea, and reflect the trend of the times relatively more. Based on these results, in future study, I will analysis how upward trending keywords are described in actual patents for concrete technology prediction.

In recent years, a recommendation system is introduced in many different fields with the beginning of the 5G era and making a considerably prominent appearance mainly in books, movies, and music. In such a recommendation system, however, the preference degrees of users are subjective and uncertain, which means that it is difficult to provide accurate recommendation service. There should be huge amounts of learning data and more accurate estimation technologies in order to improve the performance of a recommendation system. Trying to solve this problem, this study proposed a movie recommendation system based on Fuzzy-AHP and Word2vec. The proposed system used Fuzzy-AHP to make objective predictions about user preference and Word2vec to classify scraped data. The performance of the system was assessed by measuring the accuracy of Word2vec outcomes based on grid search and comparing movie ratings predicted by the system with those by the audience. The results show that the optimal accuracy of cross validation was 91.4%, which means excellent performance. The differences in move ratings between the system and the audience were compared with the Fuzzy-AHP system, and it was superior at approximately 10%.

This paper studies the impact of domestic and foreign economic activity on mobility among regions. The shortage of human resources and demand continues in Eastern Europeans. Especially Ukrainians, have entered the Polish labor market to make up for the scarce areas. As a result, Poland's supply and demand in Ukraine is disproportionate. Minimum wage increases are putting continued pressure on employers. Therefore, the regression equation in the form of job-seeker's economic activity ratio, y= AX²+B,(x=settlers) can be used to grasp the relationship between curves. According to the domestic and foreign workers who migrated, economic activities was rather than increasing the local population, the settlers of nearby large cities is more proportional. Empirical analysis has shown that the human resource hub has increased migration to large cities and industrial. The hub 'A'nation has been created for mobility in 4th wave re-industry, and the same re-industrialization (N₂) in other cities has attracted nearby human resources, but not settle. After all, the hub relationship between N₁ and N₂ is a mobile relationship. Due to wage inequality or a positive wellbeing chasm, workers are not settled plant area but a nearby city, or commuting between borders is easy to go into the hub central city. However, this proved on emerging from the relatively temporary settlers in the AI era.
