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.

Taoism is very political orientation from the start have. Internal alchemy has several factions, but southern school and northern school of taoism is typical of this. southern school begun from Zhang Bo-duan in north Song dynasty. Northern school is under Jin dynasty rule by Wang Chung-yang been established. Southern school did not create the platform, but northern school is developed mainly by the denomination from the first. Taoism is basically seek eternal life. Internal alchemy was created a unique discipline to reach the such stage with only Internal alchemy. Southern school's training methods were an elaborate series of logical structure with a counterpart, but northern school's methods is somewhat lacking logically. Southern school claim a training methods from the physical to mental through how to achieve it's ultimate goals, northern school took from mental to spiritual retreat methods that the way to achieve objectives. But northern school's theory of ascetic Practice is difficult to see that the contents are pure. Also, the labours of penance during his training process is the other way with Southern school. These differences are they closely associated with Confucianism and Buddhism, to understand the point of view. Southern school put a primary objective in the personal Practice, while northern school is fundamental to the relief of the people. This can see that has how long life times in southern school and northern school's main members. Because the members of southern school enjoyed great longevity, but northern school's main members was not enjoyed longevity. As a result, the southern school's flow is cut off and northern school became the center form a major organization in the history of china taoism. The southern school assimilated to the northern school. In a pure sense, host and guest's changed.

Many studies have been carried out to retrieve images using colors, shapes, and textures which are characteristic of images. In addition, there is also progress in research related to the disease images of the crop. In this paper, to be a help to identify the disease occurred in crops grown in the agricultural field, we propose a similarity-based crop disease search system using the diseases image of horticulture crops. The proposed system improves the similarity retrieval performance compared to existing ones through the combination descriptor without using a single descriptor and applied the weight based calculation method to provide users with highly readable similarity search results. In this paper, a total of 13 Descriptors were used in combination. We used to retrieval of disease of six crops using a combination Descriptor, and a combination Descriptor with the highest average accuracy for each crop was selected as a combination Descriptor for the crop. The retrieved result were expressed as a percentage using the calculation method based on the ratio of disease names, and calculation method based on the weight. The calculation method based on the ratio of disease name has a problem in that number of images used in the query image and similarity search was output in a first order. To solve this problem, we used a calculation method based on weight. We applied the test image of each disease name to each of the two calculation methods to measure the classification performance of the retrieval results. We compared averages of retrieval performance for two calculation method for each crop. In cases of red pepper and apple, the performance of the calculation method based on the ratio of disease names was about 11.89% on average higher than that of the calculation method based on weight, respectively. In cases of chrysanthemum, strawberry, pear, and grape, the performance of the calculation method based on the weight was about 20.34% on average higher than that of the calculation method based on the ratio of disease names, respectively. In addition, the system proposed in this paper, UI/UX was configured conveniently via the feedback of actual users. Each system screen has a title and a description of the screen at the top, and was configured to display a user to conveniently view the information on the disease. The information of the disease searched based on the calculation method proposed above displays images and disease names of similar diseases. The system's environment is implemented for use with a web browser based on a pc environment and a web browser based on a mobile device environment.

The core thought of Confucius("論語") is 'Ren(仁)'. Then, how ought we to interpret this 'Ren(仁)'? In this study, the researcher has interpreted 'Ren(仁)' from the perspective of Xiujizhiren(修己治人), which is the doctrine of Confucianism and its ideal. At first, the researcher closely reviewed Ren(仁) on the viewpoint of Xiuyang (修養). Ren(仁) is the most fundamental virtue that enables general populace to equip with their qualification as a human being. Specifically, to live like a human being, Ren(仁) is a must. That is to say, it will suffice if we only can expose well what was already cherished inside us, rather than exerting efforts to attain Ren(仁), in some contexts, that must achieve in order to live like a human being. The reason that we exert our efforts for self-cultivation is to bring this Ren(仁), which is foundation of human life, before the public. Even in relationship-building, Ren(仁) is necessary. Human being is not an existence that can live alone, but at all times, humans are required to build a relationship with others. To make this relationship-building lead into right direction, we need to think of that the standpoint of oneself and the other are identical. That is, when I myself and the other person are in the most optimal situation, then a right relationship-building can take place. This most optimal status is Ren(仁). The ideal of Confucianism is to establish a society where all people can enjoy their comfortable life. To accomplish such a society, each individual and society ought to be benevolent and to cherish humanity at the first place. That is to say, people should attain Ren(仁) from both aspects of Xiuji(修己) and Zhiren (治人). If Ren(仁) has not been attained from any of either side, then it is hard to say that the ideal of Confucianism is completely realized. However, Zhiren(治人) must be backed up by Xiuji(修己). For this reason, Kongzi(孔子) presented three steps in connection with this cultivation process, to wit, 'Cultivation of himself in reverential carefulness'(修己以敬) ${\rightarrow}$ 'Cultivation of himself so as to give rest to others'(修己以安人) ${\rightarrow}$ 'Cultivation of himself so as to give rest to all the people'(修己以安百姓). It is noticeable that Xiuji(修己) is included in all three phases. The society that Kongzi(孔子) longed for is still valid in this modern world. Therefore, Ren(仁) which was edified by Kongzi(孔子) is necessary for today's society. If we don't interpret Ren(仁) as with a fixed term lying stagnant in one place, then its definition shall be interpreted newly so as to suit the times and the situation of civil society, thus this Ren(仁) shall be the foundation for building a desirable society for humans.

Since Noron(老論) had organized in the period of Sookjong(肅宗), it constantly had led the political situation of Choson until Choson(朝鮮) perished as the grasping political power. Studies and thoughts development of Noron can be devided into four periods. First, the term of politics of faction of the period of Sookjong. Second, a period of Youngjo(英祖) and Joungjo(正祖). Third, a period of politics of power(勢道政治). Fourth, the latter term of 19century. We can look into an origin and development aspect in outline by dividing like this. The general character of Noron can be summarized by the respect of Song Si-yeol(宋時烈, 1607-1689), the theory of a party of a man of virtue(君子黨論) based on the theory of moral civilization of Choson(朝鮮中華論), the succession of Lee i(李珥; 1636-1684)'s neo-confucianism, rejecting all teaching that does not conform to neoconfucianism and protecting right studies, and oppression of Roman Catholic. The noticeable scholars of Noron were Kwon sang Ha(權尙夏; 1641~1721), Kim chang hyup(金昌協; 1651~1708), Lee jea(李縡; 1680~1746) etc. These scholars of Noron following Song Si-yeol had tried to raise "Learning of the Way"(正明道) by respecting Zushi and removing injustice(尊朱子攘夷狄), also believed people should embody moral values in their society and country. and possessed an will guiding to stabilize the country by rejecting uncivilization(尊王攘夷). Above all, they insisted, the King of Choson should rule with 'lighting heavenly reason'(明天理). Also they insisted the King and countrymen should together strive to recover civilization of moral humanity and destroy uncivilzation. But gradually they lost the motive and purpose of moral politics in the seventeenth century. Finally Noron Byeokpa(?派) take over the reins of government. It resulted in the bad effect of politics of autocrat(勢道政治) having their own way to use power of authority after death of Jungjo(正祖). The peculiar character of Noron politics can valued as the extreme aspect of 'according of politics and scholarship'(政學一致).

Objectives : This study aimed to investigate quality of life, severity of depression, suicidality, subjective health and subjective stress of depression with subjective cognitive decline in Korean adults. Methods : We used the 7th KNHANES data to enroll 415 participants with a score of 10 or higher on Patient Health Questionnaire-9 (PHQ-9), aged 20-64. Depression was divided into two groups based on the presence/absence of subjective cognitive decline. Demographic and psychological characteristics were compared between two groups. Correlation analysis of subjective cognitive decline, quality of life, depression, suicidal idea was carried out. To detect which variables influenced quality of life, a multiple regression analysis was carried out. Results : Among the 415 participants, 98 had depression with subjective cognitive decline. We identified significant differences in age, marital status, education, employment between the two groups. After adjusting for these variables, depression with subjective cognitive decline had lower EuroQol-5D index scores, more severe depressive symptoms without cognition and worse subjective health than depression without cognitive decline. There was a significant correlation between subjective cognitive decline and quality of life (r=-0.236, p<0.001), suicidal idea (r=0.182, p<0.001), depression score without cognition (r=0.108, p=0.028). Through multiple regression analysis, subjective cognitive decline was predictor of reduced quality of life (β=-0.178, p<0.001). Conclusions : Depression with subjective cognitive decline has poor quality of life and severe depression. Cognitive decline should be considered to improve treatment result in depression.

Objectives : The aim of this study was to compare activities of daily living (ADLs) according to degenerative changes in brain [i.e., medial temporal lobe atrophy (MTA), white matter hyperintensities] and to examine the association between neurocognitive functions and ADLs in Korean patients with dementia due to Alzheimer's disease (AD) and mild cognitive impairment (MCI). Methods : Participants were 111 elderly subjects diagnosed with AD or MCI in this cross-sectional study. MTA in brain MRI was rated with standardized visual rating scales (Scheltens scale) and the subjects were divided into two groups according to Scheltens scale. ADLs was evaluated with the Korean version of Blessed Dementia Scale-Activity of daily living (BDS-ADL). Neurocognitive function was evaluated with the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease assessment packet (CERAD-K). Independent t-test was performed to compare ADLs with the degree of MTA. Pearson correlation and hierarchical multiple regression analyses were performed to analyze the relationship between ADLs and neurocognitive functions. Results : The group with high severity of the MTA showed significantly higher BDS-ADL scores (p<0.05). The BDS-ADL score showed the strongest correlation with the word list recognition test among sub-items of the CERAD-K test (r=-0.568). Findings from the hierarchical multiple regression analysis revealed that the scores of MMSE-K and word list recognition test were factors that predict ADLs (F=44.611, p<0.001). Conclusions : ADLs of AD and MCI patients had significant association with MTA. Our study, which identifies factors correlated with ADLs can provide useful information in clinical settings. Further evaluation is needed to confirm the association between certain brain structures and ADLs.

In 2020, civilized society's overall lifestyle showed a distinct change from consumable analog media, such as paper, to digital media with the increased penetration of cloud computing, and from wired media to wireless media. Based on these social changes, this work examines whether the use of computer media in the field of landscape architecture is appropriately applied. This study will give directions for new computer media classes in landscape architectural education in the 4th Industrial Revolution era. Landscape architecture is a field that directly proposes the realization of a positive lifestyle and the creation of a living environment and is closely connected with social change. However, there is no clear evidence that landscape architectural education is making any visible change, while the digital infrastructure of the 4th Industrial Revolution, such as Artificial Intelligence (AI), Big Data, autonomous vehicles, cloud networks, and the Internet of Things, is changing the contemporary society in terms of technology, culture, and economy among other aspects. Therefore, it is necessary to review the current state of the use of computer technology and media in landscape architectural education, and also to examine the alternative direction of the curriculum for the new digital era. First, the basis for discussion was made by studying the trends of computational design in modern landscape architecture. Next, the changes and current status of computer media classes in domestic and overseas landscape education were analyzed based on prior research and curriculum. As a result, the number and the types of computer media classes increased significantly between the study in 1994 and the current situation in 2020 in the foreign landscape department, whereas there were no obvious changes in the domestic landscape department. This shows that the domestic landscape education is passively coping with the changes in the digital era. Lastly, based on the discussions, this study examined alternatives to the new curriculum that landscape architecture department should pursue in a new degital world.

This study is to evaluate stream flow and water quality changes of Yeongsan river basin (3,371.4 km2) by inter-basin water transfer (IBWT) from Juam dam of Seomjin river basin using SWAT (Soil and Water Assessment Tool). The SWAT was established using inlet function for IBWT between donor and receiving basins. The SWAT was calibrated and validated with 14 years (2005 ~ 2018) data of 1 stream (MR) and 2 multi-functional weir (SCW, JSW) water level gauging stations, and 3 water quality stations (GJ2, NJ, and HP) including data of IBWT and effluent from wastewater treatment plants of Yeongsan river basin. For streamflow and weir inflows (MR, SCW, and JSW), the coefficient of determination (R2), Nash-Sutcliffe efficiency (NSE), root mean square error (RMSE), and percent bias (PBIAS) were 0.69 ~ 0.81, 0.61 ~ 0.70, 1.34 ~ 2.60 mm/day, and -8.3% ~ +7.6% respectively. In case of water quality, the R2 of SS, T-N, and T-P were 0.69 ~ 0.81, 0.61 ~ 0.70, and 0.54 ~ 0.63 respectively. The Yeongsan river basin average streamflow was 12.0 m3/sec and the average SS, T-N, and T-P were 110.5 mg/L, 4.4 mg/L, 0.18 mg/L respectively. Under the 130% scenario of IBWT amount, the streamflow, SS increased to 12.94 m3/sec (+7.8%), 111.26 mg/L (+0.7%) and the T-N, T-P decreased to 4.17 mg/L (-5.2%), 0.165 mg/L (-8.3%) respectively. Under the 70% scenario of IBWT amount, the streamflow, SS decreased to 11.07 m3/sec (-7.8%), 109.74 mg/L (-0.7%) and the T-N, T-P increased to 4.68 mg/L (+6.4%), 0.199 mg/L (+10.6%) respectively.

This paper has been written to verify the existing theory that districts occurred independently in various parts of the world, including the Korean Peninsula. Song Giho (2006) claims that the origin of the Gudle, is an example of polygenism that occurred in various areas in the world, including the Korean peninsula. This argument has been corroborated by a large number of researchers. However, it is difficult to understand the lineage of Gudle and its process of development, if a theory of polygenism is continued to be taken into account. The place which is targetet by this theory is the North-West area of the Korean peninsula, south of Primorsky Krai, and in the northern area of Zabaikal-Mongolia. This means that these areas developed independently because they were far from each other and had no direct cultural relationship. However, the structure of Gudle, shape, and assemblages of earthenware it cannot be explained by polygenism, as they are the same in every place. Furthermore, it is also questionable as to the timing and region of emergence of the culture in East Asia over a limited time frame of 3-2 BC. Gudle are formed by furnaces with roofs and walls, Gorae, which saves heat, and it has smoke ventilation that draws smoke out. Therefore, the Gudle is not a structure that anyone can make without advanced technical understanding. So far, the only facility with furnaces and smoke ventilation that appear before the Gudle is Buttumak. Thus, the Gudle is likely to have been invented in the place where Buttumak were used. The area as known for the origin of Gudle was observed to verify the existence of the Buttumak's structure, but none of these facilities were found. The Gudle suddenly appeared within a new culture that had never existed before. That means that none of the three places had the conditions under which the Gudle could be invented, so it must have been introduced from outside. In conclusion, the three places that I mentioned above are not the origin of Gudle. So, the origin of Gudle has to be found elsewhere.
