There are two cultivars, 'Jeongsun' and 'Mishima' of Bupleurum falcatum L., a medicinal plant, have been cultivated in Korea. Two cultivars were evaluated and compared in details for major growth characters and their seasonal changes. Jeongsun was higher in stem length and root weight per plant, and earlier in maturity than Mishima, while Mishima was higher in top weight per plant and the ratio of outer phloem layer(OPL) to whole root, and more in branch number. Coefficients of variations of most growth characters were higher in Mishima than in Jeongsun. In relationship between root and shoot growth characters, root weight, root diameter, etc. were positively correlated with stem thickness, top weight, branch number, etc. in both cultivars. In comparison of seasonal changes for growth characters between two cultivars, stem length and node number were almost not increased after September, but root length and branch number tended to increase until November. There were continuous increases of top and root weights in both cultivars after September. Increase rates of top and root weights were higher in Mishima and Jeongsun, respectively. The weight ratio of root part to whole plant in Jeongsun and the ratio of OPL to whole root in Mishima were higher during whole growth stages; especially Mishima showed their continuous increases after October. Jeongsun flowered earlier (August 17) than Mishima (September 16) by one month. Complete flowering date was on August 30 in Jeongsun and on September 30 in Mishima. Basic difference in plant growth between two cultivars was maturity, so shoot growth almost stopped after October in Jeongsun, and continued vegetative growth until November in Mishima with late flowering habit. These results indicate that higher root weight in Jeongsun is due to its earlier flowering character leading to relatively longer time for root growth, as compared with Mishima.

This study is on the usage of bojagi recorded in Yeongjo Jeongsun Wanghu garye dogam uigwe. Major findings are as follows. The eighteenth century marked a period of entrenchment of Neo-Confucianism in the Joseon dynasty and the royal wedding was a tool to propagate Neo-Confucian values to the people. The bojagi used at King Yeongjo and Queen Jeongsun's wedding were made of simple red silk produced domestically to avoid extravagance. Uasge of costly flower-patterned silk from China was restricted to comply with the rules of the Kukhon jeongrye, which codified the royal marriage ceremony and the Sangbang jeongrye, which regulated royal attire. This modesty also shows King Yeongjo's determination to abandon lavishness.

Jeongsun limestone formations with good geochemical solution of limestone and physical environments have been developing many Karst landforms. Especially, there are many dolines and most of them elliptical shapes of planes. At present, they have been transformed into uvala toward their long diameter directions. The period of landscape processing is a Quaternary Epoch and Karst cycle corresponds to a stage from late maturity to old stage.

A research was made to describe the characteristics of alpine agricultural areas in Hongcheon, Pyeongchang and Jeongsun municipalities that comprise large alpine belts. Analysis of current land-use status, pattern classification of agricultural areas, and land-use suitability evaluation were made to describe the characteristics using GIS.

It was investigated whether developmental characteristic of foundation queens of Bombus ignitus collected in the 11 localities including Jeongsun have any effects by the first oviposition days. Materials and Methods: materials - insect : foundation queens of Bombus ignitus collected in the 11 localities. Methods - we investigated the rate of colony foundation, progeny-queen production and the number of adults emergence for the relationship between first oviposition day and colony development of B. ignitus (omitted)

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.

This paper is a study of rural settlement and housing planning in Jeongsun-Gun Kangwon Province. The method of survey to look in spot and interview, the present condition, and of the rural settlement of among the mountains. This study lays emphasis on three ri of dongmyeon Jeongson-Gun, Kangwondo retaining their present form relaytively through sample survey. Site plan of rural settlement of investigation subject involve the rural settlement in which is to search the arrangement, plan and spacial characteristic of rural settlement of among the mountains. Accordingly this study clarify the changed shape and form of rural settlement of among the mountains by selecting and put on record an scattered along.
