Recently, as text data through online channels have become vast, there is a growing interest in research that summarizes and analyzes them. One of the fundamental analyses of text data is to extract potential topics. Although the researcher may read all the data and summarize the contents one by one, it is not easy to deal with large amounts of data. Blei and Lafferty (2007) and Blei et al. (2003) proposed topic modeling methods for extracting topics using a statistical model. Since the text data is generally collected over time, it is worthwhile to monitor the topic's changes. In this study, we propose a topic index based on the results of the topic model. In addition, a control chart, a representative tool for statistical process management, is applied to monitor the topic index over time. As a practical example, we use text data collected from Blue House National Petition boards between March 5, 2018, and March 5, 2020.

Objective: Deoxynivalenol (DON) and zearalenone (ZEN) are mycotoxins that frequently contaminate maize and grain cereals, imposing risks to the health of both humans and animals and leading to economic losses. The gut microbiome has been shown to help combat the effects of such toxins, with certain microorganisms reported to contribute significantly to the detoxification process. Methods: We examined the cecum contents of three different dietary groups of pigs (control, as well as diets contaminated with 8 mg DON/kg feed or 0.8 mg ZEN/kg feed). Bacterial 16S rRNA gene amplicons were acquired from the cecum contents and evaluated by next-generation sequencing. Results: A total of 2,539,288 sequences were generated with ~500 nucleotide read lengths. Firmicutes, Bacteroidetes, and Proteobacteria were the dominant phyla, occupying more than 96% of all three groups. Lactobacillus, Bacteroides, Megasphaera, and Campylobacter showed potential as biomarkers for each group. Particularly, Lactobacillus and Bacteroides were more abundant in the DON and ZEN groups than in the control. Additionally, 52,414 operational taxonomic units were detected in the three groups; those of Bacteroides, Lactobacillus, Campylobacter, and Prevotella were most dominant and significantly varied between groups. Hence, contamination of feed by DON and ZEN affected the cecum microbiota, while Lactobacillus and Bacteroides were highly abundant and positively influenced the host physiology. Conclusion: Lactobacillus and Bacteroides play key roles in the process of detoxification and improving the immune response. We, therefore, believe that these results may be useful for determining whether disturbances in the intestinal microflora, such as the toxic effects of DON and ZEN, can be treated by modulating the intestinal bacterial flora.

The purpose of this study was to identify the professional identity levels and characteristics of occupational therapists through Rasch analysis and to use this as the basis for further assessment and research on the same subject. An online survey was conducted, and the response of 88 people working as occupational therapists between May and June 2020 was analyzed. The collected data included the frequency, analyzed by SPSS 22.0 and technical statistics, Winsteps 3.8.0 target and item suitability, item difficulty, level scale, and separation reliability. According to the analysis, 17 (16.3%) of the subjects and 5 (20%) out of 25 items were unsuitable. Item difficulty was the highest in the category "I systematically read professional publications on occupational therapy", and the lowest level of difficulty in "I make my own decisions about what to do." The three-point scale was suitable for the equilibrium scale, and the separation reliability was between .86 and .95. Thus, identity levels and characteristics of occupational therapists, the suitability of items and subjects, and difficulty levels can be identified through Rasch analysis. In the future, research should be conducted on various sample groups, to develop identity measurement tools specifically for occupational therapists, and to present items appropriate to the characteristics of their work.

In the recent modernized world, utilization of natural resources (renewable & non-renewable) is increasing drastically due to the sophisticated life style of the people. The over-consumption of non-renewable resources causes pollution which leads to global warming. Consequently, government agencies have been taking several initiatives to control the over-consumption of non-renewable natural resources and encourage the production of renewable energy resources. In this regard, we introduce an IoT powered integrated framework called as green home architecture (GHA) for green score calculation based on the usage of natural resources for household purpose. Green score is a credit point (i.e.,10 pts) of a family which can be calculated once in a month based on the utilization of energy, production of renewable energy and pollution caused. The green score can be improved by reducing the consumption of energy, generation of renewable energy and preventing the pollution. The main objective of GHA is to monitor the day-to-day usage of resources and calculate the green score using the proposed green score algorithm. This algorithm gives positive credits for economic consumption of resources and production of renewable energy and also it gives negative credits for pollution caused. Here, we recommend a green score based tax calculation system which gives tax exemption based on the green score value. This direct beneficiary model will appreciate and encourage the citizens to consume fewer natural resources and prevent pollution. Rather than simply giving subsidy, this proposed system allows monitoring the subsidy scheme periodically and encourages the proper working system with tax exemption rewards. Also, our GHA will be used to monitor all the household appliances, vehicles, wind mills, electricity meter, water re-treatment plant, pollution level to read the consumption/production in appropriate units by using the suitable sensors. These values will be stored in mass storage platform like cloud for the calculation of green score and also employed for billing purpose by the government agencies. This integrated platform can replace the manual billing and directly benefits the government.

Neo-Confucianism of Myungjae Yoon Jeung either accepted Yulgok Neo-Confucianism as it was or modified it. In this study, his Neo-Confucianism was divided into acceptance and modification in Yulgok Neo-Confucianism and examined. In the acceptance of Yulgok Neo-Confucianism, it was clarified that Neo-Confucianism of Myungjae Yoon Jeung thoroughly inherited characteristics of Yulgok Neo-Confucianism, including 'Yiguijimyo', 'Yitongguiguk' and 'Guibalyiseungildo'. However, Myungjae was not just satisfied with inheriting Yulgok Neo-Confucianism as it was, but modified and inherited the theory of Yulgok by suggesting his own original preaching. There were three original preaching of his in overall; 'emphasis on the control of Li', 'argument method on a theory of gaining knowledge by the study of things', and 'perception on moral mind, human mind and human desire'. Ultimately, it is concluded that Myungjae modified, inherited and developed Yulgok Neo-Confucianism to adjust a theory of Neo-Confucianism in a position of 'Yiguijimyo', based on 'a theory of Guibalyiseungildo' of Yulgok as a Confucian scholar of Giho school. It is consistent with his life philosophy that he avoided speculative arguments on Neo-Confucianism and pursued solid study(實工) with solid mind(實心). It is also consistent with his view of learning that he believed that theories of ancient sages were already rich that we should read them and practice their true knowledge(眞知), and making an effort on writing regardless of them was not a study of Mushil(務實). However, due to his younger students, he was classified as a scholar who emphasized the control of 'Li' the most in Yulgok school, and a new academic tie of Giho Soron was created. It is the most important significance that Neo-Confucianism of Myungjae has in that of Giho.

Lee Ik(李瀷) had put emphasis on the achievements by self-regulated academic learning through doubts, and at the same time that it was all-embracing. His academic attitude had set an example among the members of Seongho school(星湖學派), and his disciples had strived to emulate his style. The greatness of Seongho(星湖)'s study had been revealed by development of Seongho school(星湖學派) right after his death. He had argued that the six strokes of I-Ching should be read having it divided into inward and outward divine signs. He had stated his view clearly that the divine signs ranging from one stroke to six strokes were not connected, same as Shao yong(邵雍)'s method, but, the three strokes of inward divine sign as well as the three strokes of outward divine signs were independent from each other. Seongho(星湖) also had raised many questions about Shifa(筮法), and Bianyao(變爻) and Zhuzi(朱子)'s Shifa(筮法), or Yixueqimeng("易學啓蒙") "Kaobianzhan("考變占")". In view of the Shifa(筮法), Seongho(星湖) had helped Dasan(茶山) to present 'Shiguafa(蓍卦法)' by proposing different divination rule from Zhuzi(朱子)'s Method of Divination by Shiyi("筮儀"). Seongho(星湖) had not professed something significantly different from Zhuzi(朱子) in his I-xue. His study on I-xue had been accomplished under his goal of achievements by self-regulated academic learning through doubts. "Shiguakao("蓍卦攷")" is also same. I-xue of Seongho(星湖) had made a great contribution to form Dasan(茶山)'s I-xue in the later years.

The purpose of this paper is as follows: The book, , which Yi Yang-o read, is to find out what kind of series it was. Second, I will examine the way of expressing the preface that I wrote after and try to analyze the part where Lee Yang-ho took interest in . Lee Yang-o was more concerned about the soft-handedness and the eavesdropping than the person named Sasu and Kyo. It can be understood in connection with the social problems of the 18th century and the situation of Lee Yang-ho. In other words, there was a great interest in the reality, the torture of the reins of war wanted the world to live, and the was a work that reminds us of the torture of reeling. I was able to find out that Lee Yang-o was involved with the problem of reality in which he lived, criticized concrete reality contradicted reality, and struck down his intention to do so.

The purpose of this article is to consider the status and the value of a different book of Chunghyangjeon that Professor Park Sunho possesses. Chunghyangjeon that Professor Park Sunho possesses has the text in Chinese and in Korean. Compared with Chullidaebon, Chunghyangjeon that Professor Park Sunho possesses includes deletion, contraction and addition. Chullidaebon has many mistakes while Parkbon in Chinese shows that the mistakes were corrected. According to the standard, Parkbon in Chinese is similar to Mansongbon and Donambon rather than Chullidaebon and it is more similar to Mansongbon than Donambon. In Parkbon in Chinese, hypocrisy of Yangnyeongdaegun is weakened while his negative personality is magnified. And psychological description of Yangyeongdaegun is weakened and Chunghyang's beauty is magnified. Parkbon in Korean shows deletion, contraction, addition, and change. It doesn't show consciousness of lineage and deletes hypocrisy and negative personality of Yangnyeongdaegun. Also, the phrases are being deleted and contracted, which are difficult for those who do not master Chinese literature or Chinese poems. The professor Park Sunho's copy is more significant than other novels circulated at that times, for it is bound along with a copy in Korean. Compared with other editions of Chunghyangjeon and other classical novels circulated, that kind of edition, which included Korean copy, is very peculiar. The Korean-including edition shows that the Chinese literate tried to share the novel with persons who are Korean literate but cannot read Chinese characters.

This study is purposed to observe conventional expression of Hangul Ganchal. The conventional expression of Hangeul Ganchal had set a pattern from 16th century to 17the century after establishing its regular form. It is mainly found in the introduction and the conclusion of the letters. Especially, they are concretely shown at an address form and greeting in the former, a farewell and the close in the latter. Generally, a native tongue was often used in address form at Suncheon Kim's Eongan in 16th century and Hyun-Poong Kwak's Eongan in 17th century. However, a Chinese character was commonly found in the introduction at Jingbo-Eongan-Dok in 19th century. Specifically, in case of response, the conventional expression of 'read your letter' was added in greeting part. In Suneon of 16th century, this type was gradually established to the form, and in Hyuneon of 17th century, a native tongue set a pattern. However, Jingeon of 19th century, a Chinese character was mainly used instead of a native tongue. The changing form of farewell and the close showed similar pattern as the aspect of greeting form. They seemed to be more simple and repetitive in Hyuneon compared with the form of Suneon. Furthermore, a Chinese character was dominated in the conclusion of letters in Jingeon. Consequently, the paper examined the two types of letter between Hangul letters and Chinese character letters were strongly associated with each other. It is expected that more details research will be coped with next study.

This paper treats indigenous themes on of Kim Si-seup(金時習). has strong local color to the others of "Keumoh-shinhwa(金鰲新話)". This novel is set in Nam-won(南原) and Manbok-sa (萬福寺)which are used to realize the subject. Not only a folk game like Jeopo is used as important tool, but the main character of the novel is native Namwon man. Kim Si-seup stayed for a long time in Namwon. Because of this experience, he can realize unique and local setting, and then can break from the convention about a place setting of classic novel. The local color on is confirmed at . This tale have come down in Namwon, and then was recorded early 1970s. This tale is very similar with , so many researchers understood that the tale is the orginal work of . However, I suggest that is the orginal. Written with Chinese character, was very difficult to read. Besides, many Chosun scholar couldn't find this novel. Nevertheless, has a strong local color, so many Namwon people could accept this novel, and could create new folk tale easily.
