This thesis is to clarify King Jeongjo's perspective on Chunchu and critical mind on Chunchu Study in Joseon through analyzing more than twenty sets of King Jeongjo's Chaekmun: Chunchu (策文:春秋) which are included in Hongjaejeonseo (弘齋全書). Chaekmun covers extensive themes of Chunchu Study such as composition or contents of Chunchu and assessment of Chunchu and three legends, etc. With this Chaekmun, King Jeongjo emphasized importance of the scripture Chunchu as the 'great scripture for governing a nation' and stressed the need of right interpretation and understanding on Chunchu. Along with the Article Chunchu in Gyeongsagangeui in the year of 1793 and 1796, this material presents not only King Jeongjo's perspective on Chunchu and his academic characteristics but also status and major issues of Chunchu Study in Joseon with significant value in history of thoughts.

This study was carried out for development of effective preservation on animal genetic resources. Spermatogonia cells are the germline stem cells and they can be restored to adult animal with proliferation and differentiation intentionally. When the spermatogonia cells were purified from seminiferous tubules and were cultured at $32^{\circ}C$, the cells were actively proliferated. The culture medium consisted of TCM199 plus $10\%$ FCS and coculture with Sertoli cells supported cultivation of spermatogonia cells. By passing 40 days of incubation, spermatogonia cells formed the germline colony or shape of ES-like colony or reconstruction of pseudo-seminifcrous tubule shape. At 40 days, the cultured cells were no sign for differentiation to spermatocyte or spermatid. The experiment of induced differentiation of this cells is needed.

The purpose of this research is to investigate the reality behind Jeongjo's enjoyment of the palace garden. If I were to summarize the results of this research, they are as follows: First, The 'Sanghwajoeoyeon(賞花釣魚宴)' has the differentiation which decided and regularized the rules and the regulations with the annual meetings for the Kyujanggak(奎章閣). Jeongjo had held the events five times. Second, The 'Seshimdae(洗心臺) Excursion' is based on the tragic personal history of Jeongjo. There were four events. Third, Jeongjo had enjoyed the 'viewing of the waterfall(觀瀑)' of the Okryucheon(玉流川) where a lot of the water overflows right after it rains. This is worth the special mention with regard to the point that it is a temporary landscape and not an usual landscape. Fourth, As an event for the military officers, the 'Seoljungryonghohwe(雪中龍虎會)' was held seven times. This event had been held in the middle of the winter. And each of the attendees skewered a pheasant and roasted and ate it. Also, it emphasized the sovereign and the subjects being the partners of the joys and the sorrows by giving the alcoholic drinks and the music. Fifth, Jeongjo had consoled the hard work by the civilian subjects either by holding the brazier feast(煖爐會) in the winter or by granting the alcoholic drinks and the foods according to the historical facts of the brazier feasts. Sixth, Jeongjo was good at archery and enjoyed it. During the period of his reign, Jeongjo held twice Yeonsarye(燕射禮). Seventh, Jeongjo soothed his desire to get out of the busy everyday life at the royal palace garden. While appreciating the natural landscape of the backyard, he was awakened of the meaning of the Book of Changes(周易) in which all the things had been created and changed. Eighth, At the royal palace garden, Jeongjo actively prepared the place for enjoyment by the sovereign and the subjects together. It is judged that this is because, in order to materialize his political ideals, the support by all the subjects who had been close was needed. The limitation of this research is the fact that the research had been proceeded with limited to the translations, among the many old writings related to Jeongjo. With the accumulation of the excavations of the new thoughts and of the results of the translations, the researches that are deeper will be needed.

King Jeongjo had lost his father, Sado-Seja(Prince Sado) by Noron(Older Faction). Especially those who tried to kill Sado-Seja and king Jeongjo consisted of king's family-in-law of king Youngjo and Sado-Seja. Therefore king Jeongjo's first goal was to strengthen his kingship than other things because he could gain the throne overcoming the strong hinderance of Noron and king's family-in-law. King Jeongjo requested his subjects to be "Kukbyon-In"(國邊人: a person for king) pointing out the harm of the king's family-in-law and "Tangpyong-Dang"(蕩平黨: the strongest faction consisted under the rule of king Youngjo). For the purpose, king Jeongjo built up "Gyujang-Gak". Gyujang-Gak was spoken to contain and protect the writings of earlier kings superficially, but in reality, it was an apparatus to gain and train the friendly subjects for king Jeongjo. Like that, it was the most important for king Jeongjo to suppress the king's family-in-low and to win Neo-Confucian lterati over to himself's side. Until now, the politics of Joseon Dynasty had been mainly explained on the point of view of "Seonghak-Non"(聖學論). "Seonghak-Non" means that Neo-Confucian lterati were treated as real hero, not kings in the political space of Joseon Dynasty and the role of factions were recognized important. But king Jeongjo denied these ideological stream and tried to change that political system. King Jeongjo wanted to strengthen the throne through the method which insisted the king as a hero in politics. For the purpose, king Jeongjo criticized the Neo-Confucian literati's viewpoint about politics and learning at that time and anticipated to be sole leader of politics and learning on that critique. King Jeongjo aimed to destroy the dignity of "Salim"(山林: Neo-Confucian Sages) with attacking their wrong behaviors. King Jeongjo also criticized the period of king Injo when the regime of "Sarim"(士林: pure Neo-Confucian lterati) faction fully appeared as the starting period when the factional harms were getting worse. King Jeongjo wanted to previously block the oppositions to win subjects over to himself's side with criticizing the period of king Injo and to take away the initiative from his opponents with insisting "Salim-Muyongnon"(山林無用論: a theory ignoring Neo-Confucian Sages). King Jeongjo's critique was not limited just on the system of factional politics. "Seonghak-Non" eventually took root in Neo-Confucianism. Therefore king Jeongjo criticized Neo-Confucianism. He insisted that the essence of Chinese Classics was pragmatical learning, not Neo-Confucianism. Through that critique, king Jeongjo aimed to destroy the ideological base of his opponents. However, king Jeongjo failed to be a sole leader of his subjects in the both boundaries of politics and learning even though he criticized the Neo-Confucian lterati's viewpoint about politics and learning. Because he abruptly died leaving his reformational scheme behind as well as his loyal subjects guarding himself against Noron Byeok-Pa(老論 ?派: the opposing party in Older Faction) were gone behind himself. The politics of Joseon Dynasty returned to more powerful politics for king's family-in-law after king Jeongjo's death.

This study aims to investigate what flowering plant Jeongjo loved, the attitudes and the reasons, and their implications. The study method was to investigate the contents and meaning in the historical records and to describe their interpretation. Jeongjo's life was consistent with very abstinent life style. His food, clothing and shelter were simple, and he did not show the interests in music, various arts and craft, women, and so on. He did not even show his interest in the flowers and plants of fairyland, beautiful flowers and plants. Jeongjo knew various kinds of flowers, and he was proficient in artistic expressions such as literature or painting with flower material. Due to this kind of attitude, there were few cases to demonstrate his taste on the specific flowering plant. The only one that Jeongjo revealed as his favorite flower was the pomegranate. However, the pomegranate was not the simple flowering plant as the subject of enjoying to Jeongjo. The pomegranate has the meaning of indicator plant to indicate the season of rice farming. Therefore, he made it to be the intermediary to indicate the farming season, which counted a few. Besides, Jeongjo who was threatened by the trials of assassination to him in his early throne period utilized 5,600 pomegranate flowerpots as the barricade of his shelter by arraying them with the type of stone piles in $B{\bar{a}}zh{\grave{e}}nt{\acute{u}}$(八陣圖). The use of Jeongjo's pomegranate flowerpots was not related to the visual utilization like ornament at all, which was very unique case. From multiple records, it was found that the pomegranate was the flower to be with Jeongjo in his period of reign. It is remarkable that the reason why Jeongjo kept pomegranate for a long time like this had the difference from enjoying practice on the ordinary flowering plant. This study has the limitation to be conducted depending on the Korean translated data. Further studies are required according to the translation performance of new historical records.

In this study, Samryesugwon is compared with King Jeongjo's anthology because it is not clear why King Jeongjo made Samryesugwon from the Three Classics of Li in a same category but in two different text. As results of this study, it is hard to find information of title because there is no table of contents on the Samryesugwon. Also, King Jeongjo considered and respected the Yili and Zhouli as the original Classics of Li, but not the Liji. Last, it turns out that there is the passive fixed pattern in the way of abridgment instead of the unique characteristic of Jeongjo's abridgment which was compiled before. This research has an academic significance because it figure out the reason why King Jeongjo compiled the Samryesugwon and what his perspective on the Three Classics of Li by textual analyzing as abridgment book.

To evaluate the antioxidant and antitumor potential of a newly bred rice, Hiami (Suweon-511), total polyphenol content, $\gamma$-oryzanol content, radical scavenging activities, and antitumor activities were measured (control: Ilpum). Total polyphenol contents were 6.31 and 3.75 mg/g for unhulled (UHR) and hulled rice (HR) of Hiami, which was higher than that of Ilpum (5.66 and 3.47 mg/g). The $\gamma$-oryzanol contents were 33.53 and 39.47 mg/100 g for UHR and HR of Hiami, which was higher than that of Ilpum (24.33 and 28.68 mg/100 g). DPPH radical, hydrogen peroxide, superoxide radical and hydroxyl radical scavenging activities of 70% ethanol extracts of Hiami were higher compared to Ilpum, and UHR was higher than those of HR. Antitumor activities of the 70% ethanol extracts of Hiami and Ilpum were increased with a dose-dependent manner. The extracts of Hiami have higher activities of antitumor activities on gastric and breast cancer cell lines compared to other cancer cell lines, and Ilpum has higher activities of antitumor activities on colon and liver cancer cell lines.

This study investigated acoustic features in spectral moment analysis, comparing accurate articulations with distortions of alveolar fricatives such as dentalization, palatalization, and lateralization. A retrospective analysis was conducted on speech samples from 61 children (mean age: 5.6±1.5 years, 19 females, 42 males) using the Assessment of Phonology & Articulation for Children (APAC) and Urimal-test of Articulation and Phonology I (U-TAP I). Spectral moment analysis was applied to 169 speech samples. The results revealed that the center of gravity of accurate articulations was higher than that of palatalization, while palatalization was lower than dentalization. The variance of dentalization was higher than that of both accurate articulations and palatalization. The skewness of dentalization was higher than that of accurate articulations, and the skewness of palatalization was higher than that of accurate articulations. The kurtosis of palatalization was higher than that of both accurate articulations and dentalization. No significant differences were observed for the position of fricatives (initial, medial) and tense type (plain, tense) across all variables of spectral moment analysis for each distortion type. This study confirmed distinct patterns in center of gravity, variance, skewness, and kurtosis depending on the type of alveolar fricative distortion. The objective values provided in this study will serve as foundational data for diagnosing alveolar fricative distortions in children with speech sound disorders.
