In this text, the author examines the aspects and characteristics of the three forms that were created and enjoyed when the upper-class nobles of Japan "combined(混淆)" waka(和歌) and Chinese poetry(漢詩) between the 10th and 17th centuries. The three forms are the "Collection of Japanese and Chinese poems for singing"(和漢朗詠), "A collection of Japanese and Chinese poems" (詩歌合), and the "Renku renga"(聯句連歌). "Collection of Japanese and Chinese poems for singing" appeared in the 10th century, "A collection of Japanese and Chinese poems" appeared in the 12th century, "Renku renga" appeared in the 14th century, and all three continued to influence the history of Japanese literature after that time. As the combination of literary Japanese and Chinese progressed, the gap between waka and Chinese poetry decreased until they finally combined to create a single work. That is, waka and Chinese poetry converged in one place in multiple ways: as a work that was appropriate to be recited("Collection of Japanese and Chinese poems for singing"), facing each other work against work in a competition("A collection of Japanese and Chinese poems"), and, in the end, they reached the point where they were interchangeable as lines making up long poems(長詩)("Renku renga"). The combination of literary Japanese and Chinese can be said to be the Japanese version of the common movement in East Asian literary history during the Middle Ages to make songs from one's own language flawless in Chinese poetry. Meanwhile, by examining the status changes that appeared as Chinese poetry paralleled, fought with, replaced, and combined with waka, we can find clues to explain the attitudes of the Japanese people on Chinese poetry during the period when the three forms existed, as well as the characteristics of Japanese Chinese poetry that appeared in response to that. The preferences not of "myself" but of the "audience," content and expressions that revere the period rather than the inner self of the poet, and the fact that it is a means for enjoyable pleasure rather than having the original characteristics of lyrical poetry for self-expression are all characteristics of Chinese poetry in Japan during the early and late Middle Ages period. These characteristics can be said to be the current that flows in the underbelly of the history of Chinese literature in Japan. This author believes that the key to discussing the history of Chinese literature in Japan during the Middle Ages period from the perspective of East Asian literary history can be found here.

This research is to investigate his creative perspective to Deahak through Seoktan Lee Shin-Ui's Daehakcharok. Lee Shin-Ui is a scholar and politician in the middle of Joseon Dynasty. His ancestral home is Jeonui. The honor name is Gyeongchik and pen name is Seoktan. The posthumous name is MunJeong. His Daehakcharok was written in the process of taking basic foundation as the politic leader. It was a record that he usually wrote down things realized after reading Deahakjanggu. Seoktan clearly classified the meaning of Jang (chapter) and Gu (phrase) as the structure of Deahakjanggu, and created new realm about the method of classified study. In the preface of Deahakjanggu, he emphasized that the core of Deahak is in Gyeong (敬, respect or honor), and clarified that Deahak deals with Sim (心, mind) and Seong (性, human nature). In the interpretation of Daehakdeajeon, he thought that the core of Samgangnyeong (三綱領, three doctrines or essential principles) depended on Myeong (明, realizing), Shin (新, taking re-newness), and Ji (止, achieving) as the meaning of 'realizing, taking re-newness, and achieving', and interpreted the context of Tao (道, the way), Myeong (明, realizing), and Deuk (德, virtue) in detail. In addition, he interpreted various concepts and meaning of Deahak with Myeongmyeongdeuk (明明德, realizing human nature) and Sinmin (新民, renewing people) as relationship with Ji(知, realization), Haeng(行, practice), Che(體, main structure), and Yong (用, dealing with), and developed Neo-Confucianism deeply. In case of the main interpretation of Deahakjanggu, he analytically reviewed 50 phrases one by one throughout 10 total chapters. In case of chapter five which includes Zhuzi's the theory of Gyeokmul (格物, approaching things or persons), he interpreted it in three parts and classified Gyeokmulchiji (格物致知, approaching things or persons and then realizing their nature) about researching deeply of principle and each thing, and Mulgyeokjiji (物格知至, approaching things or persons and then realizing them) about all things. He arranged in order of 'principle- researching-result' as well. In final, chapter ten showing the core of politic thought emphasized the way of Hyeolgu (?矩, considering others' situation through his/her own experience) intensively and informed that it is the best virtue for a governor.

The study examined Daxuezhalu written by ShiTan Li Shen-Yi. Three different editions of Daxuezhalu were looked into, one of which in Shitanji("石灘集") could be considered methodical, if not perfect. In addition, Guojirucangben("國際儒藏本" as goudou(句讀) and correction was made on its wrong contents through dainjiao(點校) by WangXinzhu(王心竹). For these reasons, Daxuezhalu in Shitanji was used as the basis for the study and Guojirucangben as a supplement. Explanatory notes were added to Daxuezhangjuxu("大學章句序") in Daxuezhalu, but consent cannot be given to some of them, which include the author's opinion that views Jing(敬) as essence of Xiaoxue("小學") and Daxue("大學"), and the unique interpretation of Zhangju(章句), which can be attributed to the fact that the author didn't revise Daxuezhalu after writing it at the age of 37. However, the explanatory notes on xin(心), xing(性), qing(情), zhi(志) and yi(意) in An(按) toward the end of Daxuezhangjuxu are considered unique. The followings in Jingwen(經文) were examined as questionable. ShiTan(石灘) reflected on the ways to reach zhishan(至善) as in the table that shows Sangangling(三綱領), which may be viewed as distinctive. The review of zhizhijie('知止'節) reveals that ShiTan(石灘) followed Zhuzi(朱子) on the issue of whether to relocate zhizhijie('知止'節) through his interpretation for leaving it where it was. The same was applied regarding tizhi(體制) in chuanwen(傳文) by following Zhuzi(朱子)'s argument on Daxuezhangju("大學章句"). While the tendency to divide it into zhi(知) and hang(行) was seen, there was difficulty in thorough understanding with all the comments being in goujie(句節). It is considered overreaction that he argued in favor of shen(?) without any comments on Gewuzhizhibuwangzhang("格物致知補忘章"), although he mentioned characters, jin(謹) and shen(?) unlike Zhuzi(朱子).

This paper is to explain who are the authors of first-half 18th Century private prose YeonHangRok(燕行錄) written in Chinese Character and what are interest-oriented aspects of that books. As objects of study, 3 private prose YeonHangRok(燕行錄) written by No-Ron Jeon -Ju Lee's Family(老論 全州李氏) were chosen. Result of reading articles in their anthology, I found their consciousness about going to Beijing. : They aware of "The importance of YeonHang(燕行)" and when they run a mission, they take an attitude of 'observation and attention' to their experience. With that consciousness of YeonHang(燕行) in common, So-jae(疎齋), Il-am (一菴) and Hanpojae(寒圃齋) wrote their YeonHangRok(燕行錄) that mainly describe their direct experience. So-jae(疎齋) and Hanpojae(寒圃齋)'s categories of descriptions are specialized in 'Public Affairs' and 'mission', Il-am(一菴) has widened to the everyday cultures and people of Other cultures.

The purpose of this study is to explore the source of appealing which Gusadang Kim Nakhaeng's writing for ancestral rites is equipped with. Gusadang was one of the Confucianists in Yeongnam during the 18th century and was praised for his scholarly virtue of jihaenghapil and silcheongunghaeng. Although Gusadang's writing for ancestral rites and his teacher Milam Lee Jaeui's letters were even specially named as 'gujemilchal', there has been almost no research on Gusadang's writing for ancestral rites yet. Therefore, this study selects three pieces of Gusadang's writing for ancestral rites which are especially rich in emotional expression for discussion. Chapter 2 titled as 'the Reconstruction of Memory in a Microscopic Perspective' presents the reason why Gusadang's writing for ancestral rites is recognized even as a piece of work equipped with appealing. Writing for ancestral rites begins from the point that there exists memory that can be shared by both the living and the dead. In reconstructing the anecdote with the dead on the stage of ritual writing in detail, the writer's memory plays an important role. Chapter 3 titled as 'the Rhetorical Reconstruction of Elevated Sensitivity' examines rhetorical devices needed for writing for ancestral rites. Proper rhetoric is needed to upgrade the dignity of the ritual writing and arouse sympathy from the readers. Although writing for ancestral rites is supposed to express sadness in terms of its formal characteristics, it should not end up being a mere outlet of emotion. Chapter 4 looks into 'the Descriptive Reconstruction of Lamenting Sentiment'. There should be a clear focus of description to make the gesture of the living towards the being not existing in the world any longer an appealing story. While maintaining a distinct way of description, Gusadang organizes the noble character of the dead, pitiable death, the precious bond in the past, and the longing of those left for the dead systematically. Writing for ancestral rites is a field to mourn over the death and reproduce the sadness of the living through writing. To make the text written in that way get to work as ritual writing properly, it should be appealing necessarily. This study has found the fact that such appealing that gives life to ritual writing is grounded on authenticity.

The objective of this study is to suggest the transmission direction and tasks of Ssireum, and the conclusions are like below. First, Ssireum has been designated as a national intangible cultural heritage(No.131) in December 2016. Second, in the current status of preservation and spread of Ssireum, there is no system related to the transmission of Ssireum such as cultivation of professional manpower, and facilities, programs, and administration/finance for transmitting Ssireum. Third, based on the "Intangible Cultural Heritage Preservation & Promotion Act", the transmission direction of Ssireum was suggested. (1)The designation of a college to transmit Ssireum would be needed. (2)The Ssireum curriculum should be established. (3) It would be necessary to secure trainees for transmitting Ssireum. (4)The production of teaching materials for transmitting Ssireum would be needed. (5)It would be needed to secure training institutes designated in each region and also teaching personnels for transmitting Ssireum. (6)The research direction for the correct transmission of Ssireum should be set up. Fourth, based on the "Ssireum Promotion Act", the transmission direction of Ssireum was suggested. (1)It is urgent to complement provisions for transmitting Ssireum. (2)For the transmission of Ssireum, instead of the transmission direction of Ssireum as a national intangible cultural heritage in the standardized perspective, it would be necessary to seek for the joint transmission direction between South & North Korea for research & documentation of Ssireum that could be systematized/shared between South & North Korea, development/spread of contents for discovering the original form of Ssireum, and the establishment of a base of transmission system for the preservation/promotion of Ssireum through the academic/institutional exchanges regarding Ssireum between South and North Korea. Moreover, the overall and fundamental transmission measures for the education, transmission, research, record, and informatization of Ssireum, and the cultivation of professional manpower should be established. Fifth, the contents of institutional tasks for Ssireum are like following. (1)The institutional complementation of the "Ssireum Promotion Act" should be done for the domestic/foreign promotion of Ssireum. (2)For the integration of Ssireum organizations, the administrative system should be unified. (3)The standard technical system manual for Ssireum should be produced. (4)The 'Ssireum Transmission Center' should be built for the preservation and systematic transmission of Ssireum. (5)The selection of a college for transmitting Ssireum and the establishment of a system to cultivate Ssireum successors should be done. (6)It would be necessary to establish database(DB) for the use of Ssireum techniques essential for the transmission of Ssireum.

The study aims to investigate the clinical utility of Bayley-III using US norm in Korea. A total of 98 preterm infants and 93 term infants were assessed with the K-Bayley-III. The performance pattern of preterm infants was analyzed with mixed design ANOVA which examined the differences of scaled scores and composite scores of Bayley-III between full term- and preterm- infant group and within preterm infants group. Then, We have investigated agreement between classifications of delay made using the BSID-II and Bayley-III. In addition, ROC plots were constructed to identify a Bayley-III cut-off score with optimum diagnostic utility in this sample. The results were as follows. (1) Preterm infants have significantly lower function levels in areas of 5 scaled scores and 3 developmental indexes compared with infants born at term. Significant differences among scores within preterm infant group were also found. (2) Bayley-III had the higher scores of the Mental Development Index and Psychomotor Developmental Index comparing to the scores of K-BSID-II, and had the lower rates of developmental delay. (3) All scales of Bayley-III, Cognitive, Language and Motor scale had the appropriate level of discrimination, but the cut-off composite scores of Bayley-III were adjusted 13~28 points higher than 69 for prediction of delay, as defined by the K-BSID-II. It explains the lower rates of developmental delay using the standard of two standard deviation. This study has provided empirical data to inform that we must careful when interpreting the score for clinical applications, identified the discriminating power, and proposed more appropriate cut-off scores. In addition, discussion about the sampling for making the Korean norm of Bayley-III was provided. It is preferable that infants in Korea should use our own validated norms. The standardization process to get Korean normative data must be performed carefully.

In 2020, South Korea initiated research and development of a longitudinal connectivity evaluation between upstream and downstream based on stream ecosystem health. This study analyzed the migration of upstream and downstream migratory fish species, fish distribution characteristics, trophic guilds, tolerance guilds, and species composition changes from 2015 to 2020 at Songrim weir in Yeongok stream, where the cross-structure of an ice harbor-type fishway for fish movement was recently improved. A total of 5,136 fish, including 36 species, were collected and three major migratory fishes were identified, namely, Tribolodon hakonensis, Plecoglossus altivelis altivelis, and Oncorhynchus keta. According to the comparative analysis before (Pre-I) and after (Post-I) improvement of the fishway, the relative abundance of primary freshwater fish increased in the upstream section, while the number of migratory fishes decreased. The fish species that used the fishway in the Songrim weir were Tribolodon hakonensis (58.4%) and Plecoglossus altivelis altivelis(11.8%). According to the Wilcoxon Signed-Rank Test migratory fish showed a statistically significant difference (p<0.05) in the upstream and downstream, showing a biological improvement effect of the crossstructure. On the other hand, the annual change of migratory fish based on the MannKendall trend test did not significantly increase or decrease (p>0.05). Therefore, in the fish passage improvement project, it is necessary not only for physical, hydrological, and structural tests, but also for pre- and post-biological tests on the use and improvement effect of fishway.

This study was conducted to examine the changes of photosynthesis, growth, chlorophyll contents and functional material contents in light intensity and EC concentration of wild baby leaf vegetable, Indian lettuce (Lactuca indica L. cv. 'Sunhyang') in DFT hydroponics. The cultivation environment was 25±1℃ of temperature and 60±5% of relative humidity in growth system. At 14 days after sowing, combination effect of light intensity (Photosynthetic Photon Flux Density (PPFD 100, 250, 500 µmol·m-2·s-1) and EC level (EC 0.8, 1.4, 2.0 dS·m-1) of nutrient solution was determined at the baby leaf stage. The photosynthesis rate, stomatal conductance, transpiration rate and water use efficiency of Indian lettuce increased as the light intensity increased. The photosynthesis rate and water use efficiency were highest in PPFD 500-EC 1.4 and PPFD 500-EC 2.0 treatment. The chlorophyll content decreased as the light intensity increased, but chlorophyll a/b ratio increased. Leaf water content and specific leaf area decreased as light intensity increased and a negative correlation (p < 0.001) was recognized. Plant height was the longest in PPFD 100-EC 0.8 and leaf number, fresh weight and dry weight were the highest in PPFD 500-EC 2.0. Anthocyanin and total phenolic compounds were the highest in PPFD 500-EC 1.4 and 2.0 treatment, and antioxidant scavenging ability (DPPH) was high in PPFD 250 and 500 treatments. Considering the growth and functional material contents, the proper light intensity and EC level for hydroponic cultivation of Indian lettuce is PPFD 500-EC 2.0, and PPFD 100 and 250, which are low light conditions, EC 0.8 is suitable for growth.

The purpose of this study was to compare the effect of sodium fluoride(NaF) varnish and potassium iodide(KI) on remineralization efficacy of silver diamine fluoride(SDF) by measuring microhardness and evaluating surface morphology by scanning electron microscope(SEM). Artificial caries lesions were induced on extracted primary molars and vickers microhardness was measured. Specimens were randomly separated into 4 groups for treatment. The specimens in group I were treated with SDF, group II with NaF varnish after SDF, group III with KI after SDF and group IV with distilled water. After 8 days of pH cycling, vickers microhardness was measured and difference before and after treatment was calculated. For SEM, 2 samples were evaluated respectively after enamel polishing, lesion formation and after pH cycling. Group III showed highest increase in microhardness. Group I showed higher increase in microhardness than Group II but without statistical difference. Group IV showed lowest increase in microhardness value among 4 groups. On SEM image, group I, II and III showed smoother and less irregular surface compared to group IV. Amorphous crystal pellicles were observed in group III. In conclusion, SDF, SDF and NaF, SDF and KI groups showed smoother surface and increase in microhardness suggesting the possibility that remineralization effect might take place in oral conditions. In addition, in limited conditions of this study, applying NaF varnish after SDF did not increase the remineralization efficacy of SDF while KI significantly increased the remineralization efficacy of SDF. However, additional study considering various conditions that might affect demineralization and remineralization in clinical situations need to be conducted.
