This thesis is a follow-up study on HwangJeNaeGyeogSoMun(SoMun). Its purpose is the usage of '心' letter used in HwangjenaegyeogYoungChu(YoungChu). The original manuscript of this study was the Hu's Gulin Sanctum of YoungChu. It was conducted by a literature review. Typically, the word '心' means a tangible heart and an intangible mind in the same form. Therefore, in order to understand the contents of the YoungChu, which provides the basis for the basic ideology related to health care, meditation, GiGong training, yoga, practice and oriental medicine, it is necessary to understand the meaning of the word '心' letter. The results of this study are as follows. First, it means human heart. Second, it means the human chest. Third, it means mind such as angry, joy sad, fear and so on. Fourth, it means the transcendent concept like spiritual enlightenment. Fifth, it means the pericardium. Sixth, it means logical thinking. Seventh, it means center or core, Eighth, it means the name of the constellation in the eastern sky of ancient Asia. Ninth, it can be classified into the inside. It can be used as a basic data to understand the contents of YoungChu related to various categories. The limitation of it is that the classification of the '心' letter may be different from the researchers' perspective.

Cyber attacks targeting critical infrastructure are on the rise. Critical infrastructure is defined as core infrastructures within a country with a high degree of interdependence between the different structures; therefore, it is difficult to sufficiently protect it using outdated cybersecurity techniques. In particular, the distinction between the physical and logical risks of critical infrastructure is becoming ambiguous; therefore, risk management from a comprehensive perspective must be implemented. Accordingly, as a means of further actively protecting critical infrastructure, major countries have begun to apply their security and cybersecurity systems by design, as a more expanded concept is now being considered. This proactive security approach (CSbD, Cybersecurity by Design) includes not only securing the stability of software (SW) safety design and management, but also physical politics and device (HW) safety, precautionary and blocking measures, and overall resilience. It involves a comprehensive security system. Therefore, this study compares and analyzes security by design measures towards critical infrastructure that are leading the way in the US, Europe, and Singapore. It reflects the results of an analysis of optimal cybersecurity solutions for critical infrastructure. I would like to present a plan for applying by Design.

Nog-Moon Yim Seong-Joo(녹문 임성주) is a philosopher of late Choseon Dynasty of the 18th Century. He concluded that the debates between the school of Ho and that of Rack originated from the seclusion of Li(理) and Ki(氣), and theorized the new Li and Ki theory according to his own perspective. The prime point of Nog-Moon's Philosophy is said to be Li-Ki dongshil(理氣同實), Mind and Nature ilchi(心性一致) ; he proves his prime potints based on his pure and clean Ki substance. Thus Li-Ki is reduced to monism from dualism, and Mind-Nature(心 性) is reduced to mind. Since the basis of the existence of Mind is Ki(氣), Nog-moon's theory of Substance is concluded to be Ki-monism. Nog-Moon presents his great philosophy of Ki monism suggested by Jeong Myeong-Do's monistic methodology; he explains the universality of Substance and the diversity of Phenomenon with the logical structure of ilwonbunsu(一原分殊). The characteristics of Nog-Moon's philosophy is that ilwon(一原) and bunsu(分殊) are bonnyeon(本然) identical, which means Substance and Function(體用) are identical, or bonmalilchi(本末一致). It means Mind and Nature are bonnyeon(本然) identical, Ki and Mind and Nature are identical. With the expression of seongrihak (性理學) Gijil(氣質) is not different from bonnyeon(本然). Therefore 1 define the philosophy of Nog-Moon had been built on the context of a sage.

Fu-Shan(傅山, 1607~1684) was a progressive actualist between the late Ming(明) dynasty and the early Qing(淸) dynasty. He regards the intellectuals at that time as scarecrows leaned on the empty and exaggerative moral philosophy which the neo-confucian of Song(宋) dynasty established. He thinks that the neo-confucian discussion cause harmful side effects, disregarding the utility side and the variety of the actual world. His thought becomes known all in political thought and literature. He asserts that the neo-confucian ideas provides the logical frame which regulates the actual world and creates a kind of absolute moral ideology. Therefore he insists that the Saint in the true sense of the word consequently is the social reformer and revolutionist who exposes the irrational elements of society. He insists that literature also must be able to express vividness of the actual world. He thinks that genuine literature must have creative contents and find one's own free wild way. He asserts that old literary style from the mimicry is the act which goes against human natural. He thinks that the writing must be able to express the actual world.

The moral instruction expresses and conveys a abstract objects so called moral. And it pursues occurrence of moral meaning contained a emotion. In these respects, there is a resemblance between moral instruction and artistic symbolic language. Meanwhile, the poetry are a typical form of artistic symbolic language, and especially poetic symbolism is a representative and possible way that expresses accepting a meaning of abstract objects. Then a moral instruction needs to be poetic symbolism. The poetic symbolism that a moral instruction intends to resemble is a linguistic expression, but at the same time that is a expression beyond a linguistic limitation for conveying the metaphysical meaning. For this, the poetic symbolism reveals visible and concrete vehicles that imply invisible and metaphysical tenor. At this point, poetic symbolism is characterized with sameness, implicitness, polysemy, context, allness. The poetic symbolism having these characters appears personal symbol of poet as combined with creative imagination, and is experienced poetic meaning as combined with creative imagination of reader. The moral instruction as a poetic symbolism offers learning experience similar to poetic experience. The moral instruction as a poetic symbolism would be constructed not a logical or prosaic explain but symbolic form that can draw various moral meaning. For this construction, first, we might find a symbolic media for materialization of teaching contents. Second, moral teaching should be constructed to be searching moral meaning of symbolic media. Third, moral teaching should be constructed to be interpreting moral meaning of symbolic media. When teacher can construct moral instruction as possible as similar to poetic symbolism, student can learn moral meaning combined with emotion through their response and interpretation to the teaching. It is very similar to good poem that is sympathized and accommodated poet's theme by reader.

It is analyzed that the energy pattern is affected by the social matters of the disease trend where the energy consumption has been reduced following the depression of the national economy. The campaign of social distance for the people has been done by voluntary or legally due to the epidemic of the Coronavirus Disease 2019 (COVID-19). Some economic stimulus policies have been done in some countries including the United States, South Korea, and some others. It is shown the susceptible, infectious, and recovered (SIR) modeling applied by system dynamics (SD) where the logical modeling is constructed with S, I, and R. Especially, the I is connected with Society including Population, Race, and Maturity. In addition, Economy and Politics are connected to Income, GDP, Resources, President, Popularity, Ruling Government, and Leadership. The graph shows the big jump on 2020 April when is the starting month of the S value multiplication. This shows the effect of the COVID-19 and its related post-pandemic trend. The trends of OECD and non-OECD are very similar and the effect of the virus hazards causes significantly to the economic depressions.

The cyber battlefield called the fifth battlefield, is not based on geological information unlike the existing traditional battlefiels in the land, sea, air and space, and has a characteristics that all information has tightly coupled correlation to be anlayized. Because the cyber battlefield has created by the network connection of computers located on the physical battlefield, it is not completely seperated from the geolocational information but it has dependency on network topology and software's vulnerabilities. Therefore, the analysis for cyber battlefield should be provided in a form that can recognize information from multiple domains at a glance, rather than a single geographical or logical aspect. In this paper, we describe a study on the development of the cyber operation COP(Common Operational Picture), which is essential for command and control in the cyber warfare. In particular, we propose an architecure for cyber operation COP to intuitively display information based on visualization techniques applying the multi-layering concept from multiple domains that need to be correlated such as cyber assets, threats, and missions. With this proposed cyber operation COP with multi-layered visualization that helps to describe correlated information among cyber factors, we expect the commanders actually perfcrm cyber command and control in the very complex and unclear cyber battlefield.

Recently, the keyword 'convergence' has emerged in the education field. The voice of demand for the humanities is also increasing. The range of convergence of the humanities is gradually spreading to various fields such as science, technology, engineering, and the arts field. And also, the trend is to nurture the future creative convergence talent with logical, comprehensive, and creative thinking through the fusion of humanities, scientific, and empirical theories. Myths and legends contain the content of humanity's culture creation and deal with matters such as religion, philosophy, art, and science. Therefore, through the consciousness of the ancients who lived in the so-called convergence era when academic differentiation did not occur, it will be possible to reflect on the appearance of sages. In this paper, we propose a method for educating Chinese culture through the analysis of by Wen Yi-Duo, a famous Chinese scholar. He sought to find the origin of Chinese culture through myths and legends and to find national identity by restoring the concept of national culture in the period of origin. The myths and legends of China are closely related to the cultural phenomena of modern China, which will further enhance our understanding of China.

The COVID-19 pandemic reminded us again of the importance of essential workers who perform their roles in maintaining the stability of people's daily lives worldwide. Therefore, the International Maritime Organization and overseas countries designated seafarers as essential workers and proposed relevant measures for their protection to enable them to perform their role. In particular, the International Maritime Organization (IMO) urges related associations and member states to support safe boarding and disembarkation of seafarers. However, Seafarers were restricted from boarding or disembarking, shore leave and hospital treatment in certain countries owing to extreme nationalism. This study compares and analyzes the cases of international organizations and major overseas countries to provide a logical basis for the protection of seafarers who play an essential role in the safety of the global supply chain despite the COVID-19 pandemic. This study identifies the need to protect seafarers and their roles as essential workers in the shipping industry and suggests necessary aspects and institutional improvement measures for improving seafarers' working environment to strengthen the shipping industry's resilience. This study is expected to serve as future basic data for national policies aimed at reflecting the roles of seafarers as essential workers and the need to protect them.
