Le 樂 is important in Politics of the Kings. It is the same in Nothern Song period(北宋). There was an argument about Le 樂 and Lu 律 in Nothern Song Period. Those who argued were Fan-Jin(范鎭) and Sima-Guang(司馬光). They argued for 30 years. Fan-Jin insists that a standard of weights and measures is Lu and a standard of Lu is the fundamental tone of twelvenotes scale, Hwang-Jong 黃鍾. On the other hand, Sima-Guang insists that a standard of Lu is weights and measures and a standard of Le is Equilibrium and Harmony, Zonghe 中和. Fan-Jin thinks it is possible to restore a Sage King's music through the right standard of Lu. But Sima-Guang thinks it is impossible. Sima-Guang believes that the only way to restore a Sage King's music is to complete Zonghe. And Fan-Jin thinks Zonghe is the work of the king whereas Sima-Guang thinks Zonghe is the order of man and everything. The key point in the argument is Lu and Zonghe. Fan-Jin regards Lu as the basis of music, whereas Sima-Guang regards Zonghe as the basis of music. Lu is a tangible law and Zonghe is a intangible law. Although the argument between the two ended in a stalemate, the argument shows the difference between the scholars at the time.

Zhu-zi(朱子) represented the study of The Book of Odes in Song dynasty and Dai-zhen(戴震) was The Book of Odes researcher representing Wan-pai(a kind of party) in Qing dynasty. Especially Dai-zhen took critical position of Zhu-xi. Comparing Zhu-zi with Dai-zhen in the aspect of The Book of Odes interpretation, this thesis intends to review the difference and the reason of both interpretations. Especially this thesis compares Zhu-zi's interpretation with Dai-zhen's about thirty poems Zhu-zi considered filthy poetry, investigating the differences of their interpretation. Regarding the poetry Zhu-zi considered filthy as refined satire, Dai-zhen had a negative position about Zhu-zi's theory of filthy poetry. As Zhu-zi interpreted the poetry in the first person on the literary view in the time when he interpreted the lyrics in the Feng-shi, he regarded the purpose and the usefulness of poetry as feeling of words. But as Dai-zhen interpreted the poetry in the third person under a Confucian classic view, he regarded the purpose and the usefulness of poetry as refined satire. In brief, that is to say that Zhu-zi made literary interpretations of feeling of words but Dai-zhen made Confucian classic interpretations of 'Si-wu-xie'(思無邪). These two men's differences about interpretation of The Book of Odes have much importance on the historical aspects of The Book of Odes. So to speak, Dai-zhen had bibliographical approach and described the meaning of poetry objectively, following Mao-shi(毛詩) theory about the interpretation of meaning of poetry, criticizing Zhu-zi's literarary view. Dai-zhen's interpretation of The Book of Odes mentioned Above was made from long vital power of Mao-shi theory and a Confucian classic method. Considering the historical stream of Zhu-zi and Dai-zhen's interpreting The Book of Odes, The Book of Odes will be interpreted and analyzed from the various views in the future.

This research aimed to discuss the necessity of education and evil through perspective of Sunja and Hannah Arendt. In case of Sunja, it was reviewed by his opinion about Sunja as the central figure. As for Arendt, it was researched with "Eichmann in Jerusalem" as the central figure which she wrote participating in the trial process of Eichmann who was a war criminal of Nazi. Sunja thought evil as the nature of people and understood that they all are originally selfish, envious, and seeking desire. Therefore, Sunja thought it is important to properly seek human desire. He claimed Haw Seong Gi Wi(化性起僞, changing evil human nature into goodness through manner) which changes human nature from evil to goodness. A teacher who leads evil into goodness is surely needed in the process of Haw Seong Gi Wi. At the same time, in the dimension of educational content it put stress on the role of Ye(禮, manner) which lets them realize discernment so that they properly seek human desire and Ak(樂, harmony) which harmoniously controls human emotion, and key point on education regarding Ye and Ak. As for Arendt, however, she recognized evil as normal one. Even though he thought that conforming the order of superior authority was the best value and then took evil of killing many Jews in thoughtlessness, Eichmann maintained that he did not take evil but only conformed the order. This way, people could take evil in thoughtlessness in totalitarianism, and it makes circumstance that they could not take goodness. Therefore they could take evil in thoughtlessness and experience the radical evil and the banality of evil. Accordingly, political praxis which guarantees people's plurality as the words and praxis is needed. It is named natality because the truth that they are born in this world is a starting point, and makes the essence of education. In this process, teachers have to be a representative of this generation for children as new social members, and be able to keep children's newness. Sunja and Arendt have the same equality and difference in that they referred to the necessity of education to overcome human evil. It is the same quality that goodness could recover the function of community and the practice of education is considered important in the goal of education and the dimension of directivity. It is different in methodical characteristic of education that Arendt, however, suggests praxis as the way that they express themselves in totalitarianism while Sunja thought that continuous practice piling up virtue for goodness is important.

This research is a part of basic research on Gyeonggi Kamyoung focused on reconstruct personnel organization and facility of Gyeonggi Kamyoung, the only Kamyoung without a Kamyoung Record, which should have been recorded on it. Excluding Gyeonggi Kamyoung, other 7 Kamyoung each have its Kamyoung Record that shows their detailed history and set up. Due to lack of information about Gyeonggi Kamyoung, this research set objective on reconstructing Kamyoung Record of it with fragments of information on multiple historical records. By doing this, this research will also be a background for general research on distinguishing administrative unity from regional uniqueness of all 8 provinces Kamyoung. Kamyoung's personnel organization is sorted into government official from central government and Yeongli and staff. The information about the government official on this research is based on "Ki-Yung-Jang-Gae- Deung-Rok"'s personal assessment. According to it, Dosa Junggun Geomlyul had the same task and position as others in different provinces did. The difference Gyeonggi Kamyoung had was an absence of Sim Yak since 1700 while others still had it. The information about Yeongli and staff's organization was based on "Ki-Yeong-Sin-Jeong-Sa-Le". In Gyeonggi Kamyoung, along 6-Bang, there were 208 Yeongli and staff categorized into 50 different official duties. Also, compared to other Kamyoungs, Youngli's scale was smaller. Kamyoung's facility inside Pojeongmun and wall is distinguished from other Kamyoung related facilities in this research. Organization of facilities inside Pojeongmun and wall is based on "Gyeonggi-Kamyoung-Do". Like other Kamyoungs in different provinces, Seonhwadang, which is the main building, is located in the center and had a similar organization. Significant point was that Gyeonggi Kamyoung had both Youngli-Cheong and Hyeongli-Cheong at the same time. In the dense and developed area outside of Seodaemun, Gyeonggi Kamyoung had its related facility around it in small scale.

We estimated the carbon storage of coal mines reclaimed using Betula platyphylla (BP), Pinus koraiensis (PK), and Pinus spp. (PS, Pinus densiflora, Pinus rigida, and Pinus thunbergii). The carbon storage of tree biomass (TB), forest floor(FF), mineral soil (MS), and the total forest were quantified. Reclaimed sites were located in Gangwon-do, Gyeongsangbuk-do, and Jeollanam-do; reclamation was conducted at various times in each region. The carbon storage (ton C ha^-1) in FF (BP: 3.31±0.59, PK: 3.60±0.93, PS: 4.65±0.92), MS (BP: 28.62±2.86, PK: 22.26±5.72, PS: 19.95±3.90), and the total forest(BP: 54.81±7.22, PK: 47.29±8.97, PS: 45.50±6.31) were lower than that of natural forests (NF). The carbon storage in TB was lower in BP (22.57±6.18) compared to NF, while those in PK(21.17±8.76) and PS (20.80±6.40) were higher than in NF. While there were no significant differences in the carbon storage of TB, FF, and the total forest among tree species, results from MS showed a significant difference among species. TB and the total forest carbon storages in all sites increased after reclamation. Soil pH and cation exchange capacity values in BP and PS were lower than in NF. Amounts of labile carbon, available phosphate, and microbial biomass carbon in reclaimed sites were less than half of NF. There are a number of methods that could increase the reclamation efficiency. Applications of lime or organic fertilizers, as well as tillage operations, may improve soil properties in reclaimed coal mines. Additionally, pruning and thinning would increase tree growth thereby increasing carbon storage.

This paper deals with two methods regarding fact and value. One is the method of H. Putnam, which is to break the boundary between fact and value and to make a world where the two have an inherent connection. The other is the method of J. Habermas, which regards fact and value as the product of an intersubjective agreement based on argumentation. Putnam, through his position of internal realism, moves from realism to pragmatism, especially by combining the rationalist tradition of Kant and Dewey's pragmatic views. Habermas also stands in the tradition of rationalism and universalism in Kant, at the same time emphasizing the practicability of truth in Hegel's tradition of historical reason. The significance of the strategy of Putnam and Habermas is that they have attempted to revive the realm of value against the strict dichotomy of facts and values and the subsequent devaluation of rationality in the realm of value. The starting point of this attempt is that the practical foundation of rationality is laid on life and practice. This could provide the room for escaping from rationality, which prioritizes only truths that reveal facts, that is, instrument-reduced rationality, the room for the revival of practical rationality through reflection on what is the purpose of life, and, in turn, the room for resisting to pass the realm of values and norms to the logic of habitual routines or customs. However, despite such common goal, there are clear limitations to Putnam's approach due to the differences in the strategies taken on facts and values. Putnam's method can demolish the whole universal framework that is the foundation where pragmatic pluralism will be fostered, eliminating the difference between the specificity of values and the universality of norms and shaking up the status of universal ethics. Therefore, Habermas' ethical theory is proposed as an alternative to establish a basis for universal ethics by relying on communication rationality and to secure the coercion of norms and blossom cultural pluralism as a diverse lifestyle based on this coercion.

This study aims at empirically analyzing the overall mechanism of the "Gray Zone Strategy", which has begun to be used as one of Chinese major maritime security strategies in maritime conflicts surrounding the South China Sea and East China Sea since early 2010, and comparing the resulting conflict patterns in those reg ions. To this end, I made the following two hypotheses about Chinese gray zone strategy. The hypotheses that I have argued in this study are the first, "The marine gray zone strategy used by China shows different structures of implementation in the South China Sea and the East China Sea, which are major conflict areas.", the second, "Therefore, the patterns of disputes in the South China Sea and the East China Sea also show a difference." In order to examine this, I will classify Chinese gray zone strategy mechanisms multi-dimensionally in large order, 1) conflict trends and frequency of strategy execution, 2) types and strengths of strategy, 3) actors of strategy execution, and 4) response methods of counterparts. So, I tried to collect data related to this based on quantitative modeling to test these. After that, about 10 years of data pertaining to this topic were processed, and a research model was designed with a new categorization and operational definition of gray zone strategies. Based on this, I was able to successfully test all the hypotheses by successfully comparing the comprehensive mechanisms of the gray zone strategy used by China and the conflict patterns between the South China Sea and the East China Sea. In the conclusion, the verified results were rementioned with emphasizing the need to overcome the security vulnerabilities in East Asia that could be caused by China's marine gray zone strategy. This study, which has never been attempted so far, is of great significance in that it clarified the intrinsic structure in which China's gray zone strategy was implemented using empirical case studies, and the correlation between this and maritime conflict patterns was investigated.

Purpose In ¹⁸F-FDG PET/CT, the absorption of ¹⁸F-FDG due to the activation of Brown Adipose Tissue (BAT) greatly interferes with the discrimination of lymph node malignant metastasis. Warming the patient's body temperature before and after injection of ¹⁸F-FDG to prevent FDG absorption by BAT is a safe and non-pharmacological approach. The purpose of this study was to identify and select patients with a high potential for BAT activation in advance, and to investigate whether BAT can inhibit FDG absorption when the body temperature is raised for a short time by directly applying heat to the target patient. Materials and Methods Among the patients who underwent ¹⁸F-FDG PET/CT at the National Cancer Center from January 2020 to December 2020, 825 female patients (415 in the thermal group, 410 in the non-thermal group) under 50 years old were included. The thermal group was administered heat for 10 minutes before injection of ¹⁸F-FDG. For statistical analysis, the Z test comparing the ratios between the two groups was used, and logistic regression analysis was performed to correct for important variables (BMI, outdoor temperature, blood sugar) according to the results of the previous retrospective study. Results Among 825 patients, 19 patients with BAT activated (Thermal group: 5(1.2%), Non-thermal group: 14(3.41%)) accounted for 2.3% of the total. As a result of performing the Z test to compare the ratios between the two groups, the activation of BAT in the thermal group was significantly decreased (P=0.034). In the univariate logistic regression analysis, the activation of BAT was also decreased in the thermal group (OR: 0.34, P<0.05). In the multivariate results, BAT activation increased in patients younger than 45 years old (OR: 4.46, P<0.05) and outdoor temperature less than 13.2 degrees (OR: 9.97, P<0.05). BAT activation tended to decrease in the thermal group, but there was no significant difference (OR: 0.37, P=0.066). Conclusion We confirmed that the activation of BAT tends to decrease by 62.5% in the group subjected to the thermal method, and it will be of great help in preventing FDG absorption of BAT more effectively in the future.

It is very essential to estimate the water body area using remote exploration for water resource management, analysis and prediction of water disaster damage. Hydrophysical detection using satellites has been mainly performed on large satellites equipped with optical and SAR sensors. However, due to the long repeat cycle, there is a limitation that timely utilization is impossible in the event of a disaster/disaster. With the recent active development of Micro satellites, it has served as an opportunity to overcome the limitations of time resolution centered on existing large satellites. The Micro satellites currently in active operation are ICEYE in Finland and Capella satellites in the United States, and are operated in the form of clusters for earth observation purposes. Due to clustering operation, it has a short revisit cycle and high resolution and has the advantage of being able to observe regardless of weather or day and night with the SAR sensor mounted. In this study, the operation status and characteristics of micro satellites were described, and the water area estimation technology optimized for micro SAR satellite images was applied to the Daecheong Dam basin on the Korean Peninsula. In addition, accuracy verification was performed based on the reference value of the water generated from the optical satellite Sentinel-2 satellite as a reference. In the case of the Capella satellite, the smallest difference in area was shown, and it was confirmed that all three images showed high correlation. Through the results of this study, it was confirmed that despite the low NESZ of Micro satellites, it is possible to estimate the water area, and it is believed that the limitations of water resource/water disaster monitoring using existing large SAR satellites can be overcome.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation that is able to alter neuronal activity in particular brain regions. Many studies have researched how tDCS modulates neuronal activity and reorganizes neural networks. However it is difficult to conclude the effect of brain stimulation because the studies are heterogeneous with respect to the stimulation parameter as well as individual difference. It is not fully in agreement with the effects of brain stimulation. In particular few studies have researched the reason of variability of brain stimulation in response to time so far. The study investigated individual variability of brain stimulation based on circadian rhythm and chronotype. Participants were divided into two groups which are morning type and evening type. The experiment was conducted by Zoom meeting which is video meeting programs. Participants were sent experiment tool which are Muse(EEG device), tdcs device, cell phone and cell phone holder after manuals for experimental equipment were explained. Participants were required to make a phone in frount of a camera so that experimenter can monitor online EEG data. Two participants who was difficult to use experimental devices experimented in a laboratory setting where experimenter set up devices. For all participants the accuracy of 98% was achieved by SVM using leave one out cross validation in classification in the the effects of morning stimulation and the evening stimulation. For morning type, the accuracy of 92% and 96% was achieved in classification in the morning stimulation and the evening stimulation. For evening type, it was 94% accuracy in classification for the effect of brain stimulation in the morning and the evening. Feature importance was different both in classification in the morning stimulation and the evening stimulation for morning type and evening type. Results indicated that the effect of brain stimulation can be explained with brain state and trait. Our study results noted that the tDCS protocol for target state is manipulated by individual differences as well as target state.
