By virtue of the characteristics inherent in diagrams, diagrammatic reasoning has potential and limitations that distinguish it from general thinking. It is natural that diagrams rarely appeared in Joseon mathematical books, which were heavily focused on computation and algebra in content, and preferred linguistic expressions in form. However, as the late Joseon Dynasty unfolded, there emerged a noticeable increase in the frequency of employing diagrams, due to the educational purposes to facilitate explanations and the influence of Western mathematics. Analyzing the role of diagrams included in Jo Taegu's 'JuseoGwangyeon', an exemplary book, this study includes discussions on the utilization of diagrams from the perspective of mathematics education, based on the findings of the analysis.

A Podaegi is a square cloth used to carry a baby. Podaegi was an essential necessity for raising baby. However currently Koreans prefer baby-carriers, baby hip-seats, and equipments other than Podaegi. Recently, Podaegi is becoming popular around the world. Therefore, it is necessary to study Podaegi to inform Korea's traditional parenting culture product. In this research, 230 images of Podaegi were collected from paintings, photographs, postcards, films and artifacts from the late 18th century to 2000. The period of study was divided into three phases from the late Joseon Dynasty to before the opening of the port, from the opening of the port to before the liberation, and from the liberation to 2000. Types of Podaegi were categorized according to its shape and how to use. Transition process of Podaegi was examined. Podaegis were categorized into band type, blanket type, combination type, cheone type, modern type, and so on. From the late Joseon Dynasty to before the pre-openings, band type was used. From the opening of the port to liberation, all types of Podaegi appeared. Since the liberation, the use of band and blanket type has gradually decreased. Modern types have been the most popular since the 1960s. Materials of Podaegi became varied and Podaegi became a fashion-item. Later, modern Podaegi became the representative form of Korean traditional Podaegi.

Lee Neung Hwa is a scholar of the late Joseon Dynasty, renowned for his studies of Korean studies. In this thesis, the study of Confucianism and Buddhism removed the research and teachings of Confucianism as a traditional study of Confucianism. Lee Neung Hwa criticized the social functioning of Confucian texts during the late Joseon Dynasty. His criticisms reflect the historical consciousness of the late Joseon Dynasty. Lee Neung Hwa is also known as the Buddhist religion. The History of Chosun Buddhism is his masterpiece. He pointed out the differences between the Buddhist scriptures of the Joseon Dynasty and the Japanese Buddhist scriptures. Moreover, the Joseon Dynasty felt more integrated into the Japanese Buddhist kingdom than in Japan. And ineunghwa also studied the mythology of Korea. He established a universal cultural phenomenon as a universal cultural phenomenon, which belongs to any ethnic Koreans. He insisted that the Sin Gyo of Dan Gun is the identity of Korean culture. His Founding Myth was not a matter of historical fact. His Founding Myth was a tool of ideological struggle to fight against Japanese imperialism.

We study a manuscript that includes 28 oriental constellations in the flags of barracks in Gangjin. According to the Joseon Chronicles, the constellation flags in the manuscript are thought to have originated from Seon-Pil Kim (金善弼) who first made 28 constellation flags for the barracks in 1878 during the Joseon Dynasty. Seon-Pil Kim was a commander and he used the 28 constellation flags for communications in a military camp. The flags also contain 28 animals and letter-like symbols with constellation maps. We examine the constellation maps in flags in terms of shapes and number of stars, and compare them with those of constellations in the Korean and Chinese star charts such as CheonSangYeolChaBunYaJiDo (天象列次分野之圖), Joseon-Butienge (朝鮮步天歌), Suzhou (蘇州) Star Chart, and Tang-Butiange (唐步天歌). Finally, we found that the shape of constellations in the flags might be similar to those in the Chinese Tang-Butienge. We also found several errors such as the shape, connecting pattern, and number of constellations drawn in the flags. It seems that the constellation flags were unofficially used in military camps in the late Joseon dynasty. Meanwhile, the 28 constellations are divided into four groups and each group has its own color and direction. We suppose that the constellation flags might represent the positions of military camps and each group of flags has their own color based on their cardinal points.

It is generally believed that Seonjeong-jeon and Heejeong-dang respectively served as Pyeonjeon of Chang-deok Palace in the earlier and the later period of Joseon dynasty. However, such belief is based on the concept of Pyeonjeon that emerged after the time of King Soonjo's reign(1800~1834). The concept and functions of Pyeonjeon varied among times ranging from Koryo to late Joseon dynasty. In the earlier Koryo dynasty, the word Pyeonjeon signified both "Pyeonjeon in relation to Jeong-jeon" or "Pyeonjeon as a casual office for the king". The ambiguity of the word was resolved when Bopyung-cheong and Jogye-cheong were established in the earlier Joseon dynasty. These buildings in Chang-deok Palace (and only Bopyung-cheong in Gyeong-bok Palace) held rituals related to events in Jeong-jeon, as well as their exclusive political rituals. Thus, the meaning of the term "Pyeon-jeon" became restricted to its second meaning, namely a casual building for the king's everyday office work and small banquets. However, the ambiguity reemerged from around the time of King Seong-jong's reign(1469~1494). In this period, Pyeonjeon as in relation to Jeong-jeon was often referred to as "Jeong-jeon", or "Beop-jeon" from the mid-16th century. In the 19th century, Pyeonjeon as king's casual office took over the characteristics and functions of Beop-jeon. Thus, the popular notion of "Pyeon-jeon" was newly established and passed onto nowadays.

Busanjin Fortress was originally made of stone fortress for the Joseon Navy, which was located in Dongnae area in the late Joseon Dynasty. However, the Japanesque Castle of Busanjin in 1592 was built by the Japanese military during the Japanese Invasion of Korea. Since the Japanese military retreated, the Joseon Navy had renovated the fortress and had used it as a base for stationing, and it had been maintained in Busanjin Fortress until the Joseon Navy was disbanded in 1895. After the abolition of the Naval Force System, the space in Busanjin Fortress was dismantled, and the government facilities and their sites were not properly managed and repaired, eventually was sold to Japanese. As Busanjin Fortress failed to function properly, the coastal space in Busanjin became a burial ground after being reclaimed by Japanese with real estate investment in mind. Today, the traces of Busanjin Fortress have been removed by the reclamation work, and only the remains of some stone pillars remain under the name of Jaseongdae(子城臺). Thus, the old custom as the Naval base disappeared, leaving only the image of Japanesque Castle.

Song, I-Yeong (1619 ~ ?) was an active astronomer in the Joseon dynasty at the era of adopting the Shixian-li, Chinese calendar in Qing dynasty. His astronomical contribution was recorded in Annals of the Joseon Dynasty, Diary of the Royal Secretariat, Comparative Review of Records and Documents-Its Revision and Enlargement, and Treatise on the Bureau of Astronomy. In addition the details on his life and works were found at the genealogies of the Song Family from Yeonan and the Kim Family from Seonsan. His major astronomical activities can be summarized in three items. First, as a specialist astronomer, he has attempted to make a systematic observation of two comets. Second, he designed and fabricated the Jamyeong-jong, the weight-powered armillary clock, which became a typical model of the astronomical clock in the Joseon dynasty. Last, he served as a royal astronomical professor, greatly contributing on implementing the Shixian-li. Song has concentrated on performing astronomical duties for his royal official service time. Song is regarded as an important astronomer who made it possible to enforce the Shixian-li until the late Joseon dynasty.

Objectives : This paper summarizes results from review of 36 cases and medical records extracted from Yeoksimanpil, involving treatment of exogenous disease in the last Joseon dynasty, and considers significance of treatment protocols. Methods : About 130 medical records from Yeoksimanpil related to exogenous disease were reviewed, and 36 cases were extracted for closer investigation. The author examined the characteristics of exogenous diseases treated in Yeoksimanpil during the Joseon dynasty, employing Yi Suki's theory about exogenous febrile disease, and analyzed the theory from the viewpoint of epidemic febrile disease (溫病學). Results : The majority of exogenous diseases recorded in Yeoksimanpil include Sanghan (傷寒); Seo (暑); Ryeohwan (厲患); and Hongjin (紅疹). Sanghan was found to be prevalent among the exogenous diseases, but diseases caused by warmth and epidemic are recognized separately from Sanghan. Yi Suki's theory about exogenous febrile disease is similar to the basic theory of modern epidemic febrile disease, although his theory was developed independently during the last Joseon dynasty. Conclusions : Although some exogenous diseases in Yeoksimanpil were recognized separately, Yi Suki did not specify each feature nor did he focus on each symptom. Instead, the author's research suggests that Yi Suki was able to identify and treat a variety of various exogenous diseases due to his accumulation of medical knowledge and skill.

Today We have three full series of the annals of Joseon Dynasty. Taebaeksan volume which is one of them shows comparatively good maintenance but Taebaeksan volume also decomposed in patches. The size of cover and inner paper were increased in late Joseon Dynasty, but the weight, thickness and basis weight bears no relation to each other. The oxidation index of paper in annals of pre-periods of King Sunjo shows very high value. After the annals of King Sunjo, the oxidation index of paper is very similar to today's Hanji. L.a.b values of inner paper in the Taebaeksan volume are similar generally. The average length of fiber using image analysis soft ware is 8.08~9.92 mm, that like immediate value of measurement. The air fraction of fiber's range is 1.20~2.12%. It lower than today's Hanji. After considering the factors of the length of fiber, air fraction and FE-SEM, we reached that no difference between raw material of inner paper in the Taebaeksan volume.

This is a comparative study of Byung-Kwa-Ryu (Korean rice cake and cookie) of the Chungcheon Province Area in the late Joseon Dynasty, based on 「Jusiksiui」 in the late 1800s, 「Eumsikbangmunnira」 in 1891, and 「Banchandeungsok」 in 1913. This study was also compared with the recipes of 「Suunjapbang」 of 1540, 「Eumsikdimibang」 of around 1670, 「Siuijeonseo」, and Gyuhabchongseo of the late 1800s. As for the Byung-Kwa-Ryu(Korean rice cake and cookie) introduced in the recipe book, 「Eumsikbangmunnira」 recorded the most with 18 types of rice cakes and two types of Korean sweets, followed by 「Jusiksiui. There were 14 types of rice cakes, and two types of Korean sweets. 「Banchandeungsok」 had eight types ofrice cakes and six types of Korean sweets. Yogi-tteok in 「Jusiksiui」 and 「Banchandeungsok」 were foods that could not be found in other recipes. Yakgwa and Jeungpyeon were in all three books as well as 「Eumsikdimibang」. These were also included in 「Siuijeonseo」 and were introduced to most cookbooks. The materials used and the method of making it differed for each recipe. Many studies on cookbooks have focused on the Yeongnam region so far. This study served as an opportunity to confirm the dietary life data of the Chungcheong-do region through a review of the recipe books containing food from the Chungcheong-do region. In addition, it was possible to examine the ingredients and cooking methods used in each cookbook at the time through comparative analysis with the cookbooks in the Yeongnam region.
