A decrease in fertility rates causes problems such as decrease in the working-age population, and has a significant impact on national policies. Currently, the Republic of Korea has a conscription system that imposes military service on all men over the age of 18. However, the transition to the volunteer miliatry system is emerging as a social issue due to the decrease in the fertility rate. In this paper, news articles and comments searched for through the keyword ' volunteer miliatry system' were collected to analyze the social perception of the volunteer miliatry system from 2018, when the fertility rate dropped to less than 1. Some of the collected comments were labeled, and emotional levels were calculated through deep learning models. Through this study, we found that awareness of recruitment system conversion did not increase as the decrease in the fertility rate, and it was confirmed that people's interest is gradually increasing.

There have been many researches on the optimal military size of unified Korea. However, most studies have used qualitative evaluation methods using subjective data. In addition, two studies incorporating statistical methodologies fail to derive appropriate results due to errors in selection of variables and the use of subjective data. Therefore, in this study, we use the ratio data instead of the country specific defense related data for 30 major countries in the world. We applied the logic of demand and supply of economics. The supply equations were produced by regression linear equation of the active ratio and defense ratio. The demand equations were produced as an inverse curves using the same coordinate system as the supply equation. With such a method, we estimated the appropriate military size and defense ratio for each of conscript and recruit system in unified Korea about 20 - 30 years later.

Although the Korea National Guard(KNG) has a short history, it has a great meaning in that it is the first of the Korean reserve forces system. Research on the KNG has been passively conducted so far. Even so, the research conducted was limited to a fragmentary description from a historical point of view and did not identify the characteristics of the KNG. Therefore, in this study, after examining the background of the times when the KNG existed, we tried to identify the characteristics of the KNG from a new perspective from legal, institutional, military, and political perspectives. In summary, the KNG was born as an efficient system in preparation for war while receiving legal support. In addition, the adoption of the volunteer army system, a recruiting system of advanced countries, the fact that officers were trained through a separate military academy unique to the KNG, and that they contributed to rear area operations are highly evaluated from a military standpoint. On the other hand, it is negative that politicians and non-military groups colluded from the process of establishing the KNG. Finally, with this study as an opportunity, it is hoped that research on the reserve force that existed before the Korean War will become more active.

The Canadian military participated in World War I and felt the limitations of the recruitment system through the continuous shortage of troops caused by the prolonged war, therefore expanded the role and scope of female manpower. The use of female manpower, which began with medical support for the first time, increased its necessity and importance as medical support personnel were dispatched overseas and women's manpower was expanded to combat support missions for the Army, Navy, and Air Force. Since then, the proportion of female manpower has been limited to 1.5% of the total number of employees at the end of the Second World War and the reduction of troops and the dismantling of the women's unit. In this situation, the Austrian Defence Force gradually accepts the recommendation of the Royal Canadian Women's Status Committee to improve the service conditions of women, marking a turning point in expanding the role of women in the Canadian military. The the Austrian Defence Force conducted long-term combat experiments to increase the proportion and role of female manpower, increasing reliability through observation and analysis to prove whether female manpower is suitable for combat troops. Korea also wants to draw implications for the future direction by comparing the history and current appearance of the Canadian military's use of female manpower with the Korean military at a time when the problem of a shortage of troops is emerging due to the recent decline in fertility and low birth rates.
