The implementation of Daedongbeop of Gyeonggido after throne of Gwanghaegun, the Daedongbeop of Gangwondo afterthrone of Injo, and the Daedongbeop of Chongcheongdo and Chollado after throne of Hyojong were in expectation of new kings the greatest Governing Administrator who tried to improve the hard life of the people, It was possible because there was a great effort. However, after throne of these three kings, the enactment of the Daedongbeop is a major crisis. The difference of the crisis related to enforcement was that the enforcement of the Daedongbeop of the Gwanghaegun and the Injo was carried out immediately after the enforcement decision was made but soon it was put into a crisis of abolishment and the Chungcheongdo and Chollado provincial Daedongbeop encountered extreme opposition before the enforcement and it has been carried on continuously since the end of the abolition crisis. In this study, we examined the efforts of the Governing Administrator who succeeded in the enactment of the Daedongbeop for the peaceful life of the people, with the throne of these three kings and the expectation of the new king. In the case of at the time of Gwanghaegun, Hanbekgyeom, LeeWonik, and Hwangshin, Joeik and LeeWonik at the time of Injo, and Kimyuk at the time of Hyojong were common people who have tried to improve the troubles of the people. They did not focus only on the theoretical interpretation of Neo-Confucianism, but on the basis of the interpretation, they demonstrated the power of the Governing Administrator practicing the right politics for the people in reality. The result is policy formulation and enforcement for the implementation of the Daedongbeop.

Tiarella polyphylla D. Don(Saxifragaceae) is a perennial herb and distributed in China, Japan, Taiwan and Korea. Especially, it only grows in Ulleung island of Korea. It has been using for asthma, bruise and audition troubles with main components of some Triterpenoids and seven oleanolic Saponins. There is only known its chromosomal number rarely and cytogenetic study was not done. From this study, karyotype analysis and chromosomal localization of 5S and 45S rDNAs using bicolor-FISH(fluorescence in situ hybridization) were carried out. The somatic metaphase chromosome number was 2n=2x=14 and the size of chromosomes ranged $1.66{\sim}3.50{\mu}m$. The chromosome complement consisted of four pairs of submetacentrics(chromosomes 1, 2, 3 and 6), two pairs of subtelocentrics(chromosomes 5 and 7) and one pair of telocentrics(chromosome 4). We also observed NOR(nucleolus organizer region) on the chromosome 4. In bicolor-FISH, one pair of 55 and 45S rDNA sites was detected on the centromeric region of chromosome 3 and short arm of chromosome 4, respectively. Bicolor FISH was very useful tool for the localization and identification of rDNAs on the chromosomes in Tiarella polyphylla.

I will critically argue the Mencian idea of sharing pleasure with the people in the light of happiness as emotion. Happiness as a subjective mental state can make troubles with good life in being at odds with real lives. Thus, what pursues genuine happiness goes back to a classical question of how one ought to live for good life over the subjective mental state. For this, I will focus on concepts of 'pleasure alone (tongnak)' and 'sharing pleasure with the people(yeomin-dongnak)', which can be seen in the dialogue between Mencius and King Xuan of Qi. I will show that king Xuan's pleasure as subjective happiness has discord with his good life because of the hierarchy of his desire. I will explain how to unify good life with pleasant one by the idea of sharing pleasure with the people provided by Mencius and examine certain dynamics of sympathy and mutual understanding under solidarity. Moreover, I will investigate how such power of sympathy as compassion can be connected with sharing pleasure with the people. Compassion and yeomin-dongnak can be captured by the golden rule of a measure to gauge others(shu). I will delve into how to differ from one another and summarize Confucian idea of yeomin-dongnak as happiness in terms of the theoretical frame related to good life(welfare). I briefly conclude how subjective happiness can contribute to making our lives better.

Helicobacter pylori, a gram-negative bacterium, is one of the risk factors that induces gastritis and gastric cancer. Therefore, much attention has been paid to the compounds that inhibit bacterial growth or eradicate bacteria. Evodiae fructus (EF), the fruit of Evodia rutaecarpa, has been used for treating diarrhea and abdominal pain. EF extract was already found to inhibit the growth of H. pylori. However, to the best of our knowledge, the effect of EF on the virulence factors of H. pylori has not been reported. In this study, when comparing the minimum inhibitory concentration (MIC) of the different methanol concentration extracts, the 95% methanol extract (EF95) showed the lowest MIC value. EF95 extract suppressed the expressions of cagA, vacA and ureB, but interestingly, it up-regulated the expression of ureA. A decrease in production of ammonia in the culture medium and the cell lysates indicated that EF95 inhibited the urease activity in H. pylori, which was the result of EF95 inhibiting the ureB expression. Although the mechanism by which EF95 extract regulates the virulence factors in H. pylori needs further study, EF95 could be used for treatment of gastric troubles induced by H. pylori.

The LIDAR sensor, which provides higher cognitive performance than cameras and radar, is difficult to apply to ADAS or autonomous driving because of its high price. On the other hand, as the price is decreasing rapidly, expectations are rising to improve existing autonomous driving functions by taking advantage of the LIDAR sensor. In level 3 autonomous vehicles, when a dangerous situation in the cognitive module occurs due to a sensor defect or sensor limit, the driver must take control of the vehicle for manual driving. If the driver does not respond to the request, the system must automatically kick in and implement a minimum risk maneuver to maintain the risk within a tolerable level. In this study, based on this background, a LIDAR-based LKS MRM algorithm was developed for the case when the normal operation of LKS was not possible due to troubles in the cognitive system. From point cloud data collected by LIDAR, the algorithm generates the trajectory of the vehicle in front through object clustering and converts it to the target waypoints of its own. Hence, if the camera-based LKS is not operating normally, LIDAR-based path tracking control is performed as MRM. The HAZOP method was used to identify the risk sources in the LKS cognitive systems. B, and based on this, test scenarios were derived and used in the validation process by simulation. The simulation results indicated that the LIDAR-based LKS MRM algorithm of this study prevents lane departure in dangerous situations caused by various problems or difficulties in the LKS cognitive systems and could prevent possible traffic accidents.

Since the middle of the 19th century, East Asia, especially Korea, was oppressed externally by the imperialism of Japan and others while internally long-lasting political convention like in-law government was driving the country into troubles at home and abroad. Witnessing such a situation and building up scholarly capability through reading over nearly all spheres, a Confucian philosopher, Ch'oe Han-gi (崔漢綺, 1803-1877), philosophized about the clue to the solution of such a choking phenomenon. Ch'oe believed that there was movement, ki (matter, material force, energy) of revolving transformation inherent in all things, people, or objects. Grasping even the principle and order of existence inherent in things from the viewpoint of ki, he tried to change the traditional theory on the law of existence of things that there existed an ontological reason lacking in motility, which was more dominant than anything existing in the universe and which ruled over the world. From this, he elucidated that the Way, an identity that rules over all affairs and things, was not simply one but diverse. This means, on one hand, that he tentatively accepted the relativity of things. On the other hand, he also taught us "oneness in all things" in which all including human beings exist in close connection to each other transcending the relativity or "agreement" in which they exist in harmony as one and "unity" in which they are united into one.

Generally transition of Thought from Wang Yangming(王陽明) to Liu Zongzhou(劉宗周) is construed from emphasis of subjectivity to emphasis of intention(意; Yi). This Transition from emphasis of subjectivity to emphasis of intention is definitely expressed between Wang Yangming's Four-Sentence Teaching(四句敎) and Liu Zongzhou's explanation of Wang Yangming's Four-Sentence Teaching. Wang Yangming's Four-Sentence Teaching evoked much controversy among scholars of Yangming school. Consequently Four-Sentence Teaching's controversy caused Yangming school's division. Also this was a representative controversy on the transition period from The Ming Dynasty to The Ching Dynasty. Liu Zongzhou's critique and exposition of Four-Sentence Teaching was result from this controversy. The difference between Wang Yangming's Xinxue(心學) and Liu Zongzhou' Xinxue(心學) is due to different interpretation of intention. As is generally known Wang Yangming interprets intention is in heart stiring, but Liu Zongzhou interprets intention is being before heart stiring, immanence in heart. Liu Zongzhou suggests new exposition of Four-Sentence Teaching on intention being before heart stiring, immanence in heart. Liu Zongzhou's critique and exposition is not only criticizing Yangming's Four-Sentence Teaching, but also solves troubles of the times. As a result he promotes theory of Xinxue(心學) being peculiar his own.

This thesis is studing Kim Chi-in's Life and Confucianism-Buddhism-Taoism-Unity of Namhak lind on Jinan in Junbuk. He combined thought of Confucianism-Buddhism-Taoism and drawed up religious doctrine, after spotting internal and external troubles of nation. Kim Chi-in was influenced by Lee Un-gyu's thought of Confucianism-Buddhism-Taoism-Unity. He spoke with emphasis of Tao in doctrine through religious experience. The root of Tao originates in heaven. Although Tao was divided according to Confucianism, Buddhism and Taoism for the human's aspect of thought, it is ultimately the one. In time on explaining the one, he invoked 'eum(陰)', 'yang(陽)', 'che(體)'와 'yong(用)' as concepts of Neo-Confucianism. This ididn't incline to one side of Confucianism, Buddhism and Taoism. While he spoke with emphasis on Confucianism's ethics of 'yang' and 'yong' with Buddhism and Taoism's divine of 'eum' and 'che' as the center, he want to find pivot of thought. He especially seeked Younggamu(詠歌舞) of sing and dancing on training mind and body. This was that he let the people and scholars in retirement demand realization of Tao and aim at real virtue. The study of Kim Chi-in's thought and religion of Confucianism-Buddhism-Taoism-Unity will be an opportunity look around his identity for the traditional native thought and universality.

This study conducted an online and offline survey of 210 people from March 11 to 27, 2021 for the purpose of investigating and analyzing the current status of skin stress recognition and beauty care behavior due to wearing masks. The collected data were analyzed using SPSS 25.0 with Cronbach's α, Frequency Analysis, Chi-square test, and One way Anova. The average daily mask wearing time of more than 7 hours during the Covid-19 period was 43.8%, and skin stress recognition by wearing masks was highest among those in their 30s (M=4.27) and service workers (M=4.64), and those with acne and skin troubles (M=4.47) perceived high stress. The most important factor for home care treatment was cleansing(67.6%) and for beauty care was skin care(36.7%). Considerations factors on beauty care were 54.3% for service and customer care capabilities, and on body shape management method 45.7% for exercise. According to this study, respondents are recognizing skin stress due to the long-term use of masks, and home care treatment has been increasing as the esthetic salon has become unstable to visit due to the Covid-19 epidemic.

Objectives : Plantaginis asiaticae Folium (PA) has been widely used in Korean medicine for treatment of liver disease, stomach troubles and inflammation. We investigated the effect of PA on lipid accumulation in 3T3-L1 according to extraction conditions. Methods : The MTT assay was employed to evaluate the cytotoxicity of PA extracted by different solvents (water, 50% ethanol, and 95% ethanol) on 3T3-L1 preadipocytes. Oil red O staining was used to identify intracellular lipid accumulation in 3T3-L1. 3T3-L1 adipocytes were treated with PA at concentration ranging in 0.1, 0.2 and $0.4mg/m{\ell}$. PA was extracted by different extraction conditions such as extraction solvents, extraction time, and extraction temperature. In addition, UPLC analysis was used for determination of candidates of active ingredients in PA. Results : 3T3-L1 preadipocytes were treated with PA extracted by different solvents (water, 50% ethanol, and 95% ethanol) and there was no cytotoxicity. Oil red O staining was employed to identify the effect of PA on lipid accumulation in 3T3-L1. In the present study, PA water extraction at $70^{\circ}C$ for 6 hours decreased greatly in lipid accumulation. The range of concentrations was 0.1, 0.2 and $0.4mg/m{\ell}$. Concentration at $0.2mg/m{\ell}$ was the most effective one among them. Candidates of active ingredients in PA were shown plantamajoside and acteoside through UPLC. Conclusions : These results suggest that the effect of PA water extraction at $70^{\circ}C$ on lipid accumulation in 3T3-L1 is superior to other extraction conditions. We suppose that plantamajoside and acteoside may be candidates of active ingredients in PA.
