Kangrung is a royal tomb for King Myoungjong and his wife, Queen Jeongsun. According the record, Myoungjong died on 1567 and was buried in the present location at Gongrungdong, Nowonku, Seoul. During the 2006 repair for the Jeongjagak (memorial hall) and Bigak (tombs' house) of Kangrung, a dendrochronological analysis had been conducted. We took 79 samples, 74 from Jeongjagak and 5 from Bigak, respectively, for dating. There were three major cutting groups, i.e., 1692-1694, 1737, and 1859-1861. The first group was well matched with the date of reconstruction, which was written on the 'Sangryangmun', a formal record about building activities. The tree-ring results confirmed that the present buildings of Jeongjagak and Bigak in Kangrung were reconstructed in 1695. The second and third cutting groups indicated major repairs in Bigak.

Tree-ring chronologies can be used to date historical buildings or furnitures by matching them with chronologies of living trees. Tree-ring dating gives a calendar year to each tree ring and produces the cutting dates of logs or woods. In this study, we intend to extend our tree-ring dating applications to Korean furnitures. As a case study, we examined two traditional furnitures, one cabinet 'Jang' and the other chest, 'Bandaji'. The cutting date of the cabinet woods was A.D. 1839. The date of the outmost ring in the chest was A.D. 1904. Due to no bark present, the cutting date of the chest was only estimated as $1930{\pm}10$ by 'sapwood rings' estimation method. Ring-width pattern of the latter one also indicated that the origin of the chest must be Kangwon province. This case study suggests that tree-ring dating would be a useful and accurate method to identify the critical dates for the chronicles of Korean traditional furnitures.

Tree-ring dating can be used to date scientifically prehistoric timbers, historical buildings or woodcrafts. It gives a calendar year to each tree ring and produces the felling dates of logs or wood panels. In this study, we applied tree-ring dating to two medicine cabinets, known to be made in Kyônggi Province. Two cabinets were dated A.D. 1884 and 1874 to the last rings, respectively. Even with closed ages, two cabinets show different styles and structures. Tree-ring patterns indicated that the origins of woods for both cabinets would be near Sorak mountains and Kangneung area in Kangwon province.

China and Korea have a long history of star charts, dating from the prehistoric period. Historically, Korean astronomy has been deeply influenced by China over the last two thousand years, particularly on constellation system. Therefore, Chinese and Korean traditional star charts have many similarities in terms of shape of constellation, number of star, and so forth. Korean star charts, however, have lots of unique characteristics distinguishing from Chinese ones, such as, size of star and position of constellation. Overall knowledge of the Chinese star chart is required to study the Korean star chart. In this paper, I focus on introducing selected star charts in China and Korea. Although this review is very limited, I hope that this paper is helpful in research in the field of historical astronomy.

The National Foundation Day of Korea (개천절, 開天節) is currently celebrated on October 3 in Gregorian calendar. We review the history of dating the National Foundation Day of Korea and make a suggestion that it be celebrated on October 3 in the lunar calendar. We present numerous historical records on heaven-worship rites supporting the date October 3 in the lunar calendar. It is pointed out that October 3 in the solar calendar has been adopted in 1949 by the National Assembly with the thought that the lunar calendar is inferior and behind the times. The thought originates from misunderstanding on the value of the lunar calendar and from the ignorance of importance of history and tradition. Since there are now many national holidays that follow the lunar calendar, the logic of the National Assembly in 1949 also makes no sense. We emphasize that the lunar calendar should be followed for the National Foundation Day of Korea for its historical and symbolic characteristics restoration. We also investigate the year of the foundation of the first country of Korea, Dangun Joseon. It is found that even though the majority of the literature before late 15th century recorded the beginning year of Dangun Joseon dynasty to be equal to that of Liao Dynasty (堯), it was accidentally changed to the 25th year of Liao Dynasty in 1484 through a misinterpretation of the previous records. We claim that the beginning year of Dangun Joseon should be set to that of Liao Dynasty as recorded in the original literature in the earlier days. According to the two main opinions accepted by Korea, the beginning year of Liao Dynasty was 2357 B.C. or 2333 B.C., which correspond to the year of Gap-Jin (the 41st year of the sexagenary cycle) or Mu-Jin (the 4th year of the sexagenary cycle), respectively.

After the revision of the Urban Park Act in 2005, historical parks emerged in Korea to promote the preservation of historical heritage while also offering recreation and education to ordinary citizens. It is now time to examine the characteristics of domestic historical parks by examining their current operational conditions, and seek appropriate institutional improvements. By studying the characteristics of historical parks in various countries, as well as the trends in the designation and development of domestic historical parks, this study attempts to examine the function and role of historical parks, and seeks a direction for future action. Through its literature review, this study also examines the current state of historical parks through cooperation with relevant public officials and experts. The results of the study show that, despite historical resources being concentrated in sites dating to the Joseon Dynasty, they also include heritage pertaining to persons, events, and places. There is also a trend toward increasing the focus on modern heritage. Historical parks show differences across existing cities and new towns, as well as between major cities and provincial cities. Provincial cities showed a recent trend of using historical parks as important resources for strengthening their economics and solidifying their identities. Also, there are many cases where the designated category for a park is changed to a historical park. In such cases, there may be a problem where certain functions of the park run into conflict. Domestic historical parks can be divided into four categories: heritage parks, memorial parks, historical theme parks, and historic parks. Such detailed classification schemes may serve as the strategic foundation for later conservation and usage of historical heritage, as well as a standard for suggesting concrete direction in the operation of historical parks.

Yungneung is the royal tomb of King Jangjo (the Crown Prince Sado, 1735~1762) and his wife, Hyegyeonggung-the Lady Hong (1735~1815). King Jangjo was the second son of the 21st King Yeongjo of the Joseon Dynasty. The tomb of King Jangjo was originally established at Yangju near Seoul in 1762 and moved to Whaseong near Suwon in 1789. We examined tree-ring (dendrochronological) dates of Jeongjagak, the ceremonial hall and Bigak, the tombstone house of Yungneung. We obtained tree-ring dates of 54 wood elements. The dates of bark rings were A.D. 1785, 1786, and 1787 with completed latewoods. These tree-ring dates were well matched with the historically recorded date of two buildings, A.D. 1789 when two or three year-storage after cutting logs was considered. The results indicated that the present buildings of Yungneung was built when the royal tomb of King Jangjo was moved from Yangju to Suwon. A historical record about the construction of Yungneung, 'Hyeonyungwon-eugye' confirmed the majority of woods was moved from 'Manrichang', an official storage office in Seoul through Han river and Yellow Sea to Suwon.

The purpose of this study is to identify the species and to date the woods used in the Keunjung-jeon Hall, main building of the Kyungbok palace in Seoul. Samples (144) were divided into two parts, pillars (52) and other wood materials (92). Only two species were identified. They were Abies holophylla Max. and Pinus densiflora Sieb. et Zucc.Eleven among 20 Pyungju (outer pillars) were Abies holophylla, and 9 were Pinus densiflora. Seven among 12 Naejinkoju (inner pillars) were Abies holophylla, and 5 were Pinus densiflora. Three among 4 Gwikoju (inner corner pillars) were Abies holophylla, and one was Pinus densiflora. In the other wood materials, only 2 of 92 were Abies holophylla, and the others were Pinus densiflora. Tree-ring dating proved that this building was reconstructed during late 1860s. It also revealed that the old woods cut in the 17th century were reused.

This paper focuses on the dating and provenance of two paintings, Climbing the hill and View from St. John's Fort by the prominent Singaporean artist Liu Kang (1911-2004). Climbing the hill, from the National Gallery Singapore collection, was believed to have been created in 1937, based on the date painted by the artist. However, a non-invasive examination unveiled evidence of an underlying paint scheme and a mysterious date, 1948 or 1949. These findings prompted a comprehensive technical study of the artwork in conjunction with comparative analyses of View from St. John's Fort (1948), from the Liu family collection. The latter artwork is considered to be depicting the same subject matter. The investigation was carried out with UVF, NIR, IRFC, XRR, digital microscopy, PLM and SEM-EDS to elucidate the materials and technique of both artworks and find characteristic patterns that could indicate a relationship between both paintings and assist in correctly dating Climbing the hill. The technical analyses were supplemented with the historical information derived from the Liu family archives. The results showed that Climbing the hill was created in 1948 or 1949 on top of an earlier composition painted in Shanghai between 1933 and 1937. As for the companion View from St. John's Fort from 1948, the artist reused an earlier painting created in France in 1931. The analytical methods suggested that Liu Kang used almost identical pigment mixtures for creating new artworks. However, their painting technique demonstrates some differences. Overall, this study contributes to the understanding of Liu Kang's painting materials and his working practice.

This report includes an extensive bibliography of research articles investigating various facets of rearing neonatal piglets using liquid diets, and includes historical publications dating back to the 1940's. However, in order to provide concise and timely focus for application in modem swine production, only a selected number of recent findings are reviewed in detail. Collectively, the data presented illustrate that growth of piglets fed liquid diets can greatly exceed that of littermates fed dry diets and can even exceed growth rates of sow-reared controls (by up to 160%). The central questions that remain unanswered are: 1) Can this improved performance be obtained routinely and economically under applied farm conditions? and if so, 2) Does improved growth during the early-weaning period translate into improved net economic returns overall? Unfortunately, due to the current practical management constraints related to liquid-diet feeding (i.e., lack of an easy-to-manage feed delivery system), limited data are available which examine the efficacy of liquid-diet feeding under practical, commercial farm conditions.
