So far, it has been a general opinion that 'Hunminjeongeum' creation was made only by King Sejong himself under Jiphyeonjeon scholars' help. However, this paper stresses that 'Hunminjeongeum' was made not only by King Sejong but also by Sinmi's positive effort on King Sejong's secret order, and examines the possibility of the culture-convergence contents related to these tales as well. To reveal the ground, the method of this research was proceeded particularly focusing on following texts: Sejongsillok, Munjongsillok, Hangukbulgyojeonseo, etc. The result was as followings. 1) King Sejong's absolute trust in Sinmi, 2) Sinmi's outstanding linguistic talent in Sanskrit. 3) King Sejong's donation of Amitaba-Triad Buddha images to Bokcheonsa Temple and Sejong's granting a respecting title of 'Wugukise Hyeogakjonja' to Sinmi. 4) Sinmi's vow to educate and spread 'Hunminjeongeum' based on Buddhism, and 5) Sejo's visit Sinmi at Bokcheonsa Temple. Furthermore, if the tales related to 'Hunminjeongeum' creation are activated into a type of national or regional events or festivals without remaining simply in a story level, it would be a good way to spread the excellence of convergence K-culture with various culture contents.

The King George Island, where the King Sejong Station is located, represents one of the gateways to the Antarctica from the point of its geographical aspect. It also serves as an advanced post, and plays an important role in the extending for Korea's Antarctic research activities. The existence of maps is not only a basic element for the constructing geographic informations supporting these activities, but also an implied way of announcing the sovereignty over the KingSejong Station in global world. However, the precise surveying for the geographic information has not been carried out, and thus topographical maps as well as geographic information assuring enough accuracy are still missed in this area. This fact had forced Korea to rely on using maps produced by foreign countries. Therefore, this study aims to generate digital topographical maps of 1: 5,000 scale for the constructing geographic information using lightweight aerial photogrammetry system first. And further, it will contribute to offer practical base data for the future research related to the Antarctic environment through the analysis of glacier retreat and change using this new digital map comparing with existing one.

This study is on the reproduction of King Sejong's costume presented in at the National Classical Music Institute in the late of 2008. The performance was presented focusing on the idea of ceremonial music of hoi-ryeyeon produced in the reign of king(1433). The reproduction of King Sejong's costume was undertaken to keep pace with the times and to pay due regard to the performance costume. The implications of the study are as follows. King Sejong's Hoi-ryeyeon ceremonial costume is a royal robe(gonryongpo), the best one of king's clothing. The basic type of gonryongpo is that of fastening four yongbos to danryoung. The type of gonryongpo is, therefore, made with reference to unearthed articles and portrait of the first king of the Yi dynasty. The yongbo is larger one than the late period of the Yi dynasty in the light of portrait of the first king of the Yi dynasty. The supporting type of gonryongpo is that of gonryongpo, dapho, and chulrik, king's dress granted by Myeong dynasty. In the late period jikryeong was used as supporting dress and fixed to be lining and included jikryeong. Therefore the order of supporting dress was jikryeong, dapho and chulrik and was reproduced with reference to unearthed articles in the early Yi dynasty, as did the small piece of crown, belt and shoes.

Penguins are one of the key constituent organisms in the Antarctic ecosystem. A total of 18 species of penguins occur only in the southern hemisphere from the Galapagos Archipelago to southern area off Australia and New Zealand, South Africa, South America, and the islands scattered in the Southern Ocean to the coast along the Antarctic Continent. In the Antarctic Treaty area, there are only 5 species of penguins such as Emperor (Aptenodytes forsteri), Gentoo (Pygoscelis papua ellsworthi), Adelie (P. adeliae), Chinstrap (p. antarctica), and Macaroni (Eudyptes chrysolophus) penguins. Two additional species, the King (Aptenodytes patagonicus patagonicus) and Rockhopper (Eudyptes chrysocome) penguins, however, are distributed within the Antarctic Convergence. In the vicinity of king Sejong Station located in King George Island, the South Shetland Islands off the Antarctic Peninsula, 5 species are observed, among which 2 Pygoscelis species such as the Gentoo and Chinstrap penguins hatch their eggs and raise their chicks at the rookery 2km south offing Sejong Station in summer. Adelie penguins hatch their chicks in other place in King George Island. One Emperor penguin roamed on the frozen Maxwell Bay which has been frozen every two or three years with the approximate thickness of 60cm. And one Macaroni penguin also visited the rookery in summer. We should carry out researches on the penguins occurring in the vicinity of King Sejong Station to monitor the environmental changes around King Sejong Station and the South Shetland Islands.

The variation of geomagnetic field and absolute magnetic field at the geomagnetic observatory of King Sejong Station has been measured with 3-component ring core fluxgate magnetometer, proton magnetometer and D-I magnetometer. With data obtained from King Sejong Station during 2003, thediurnal and annual variations of geomagnetic field were researched and compared with those at other observatories. The deviation of daily variation of magnetic field in antarctica decreased gradually during winter season due to sun effect. The rates of componental annual variation of magnetic field at King Sejong Station were calculated using the least-square method under the assumption that the annual variation of magnetic field is linear. The rates are -55.93 nT/year in horizontal intensity, -0.87 min./year in declination, 58.30 nT/year in vertical intensity, and -69.85 nT/year in total intensity of magnetic field. A remarkable variation was caused by the magnetic storms occurred on 29~30 October, which were so powerful that the variation was observed in mid latitudes as well as high latitudes. The values of variation are generally 1500 2000 nT in Antarctica including King Sejong Station, 350 500 nT in East Asia. The measurement of absolute magnetic field shows that ring core fluxgate magnetometer has relatively large error range under cold temperature.

The King Sejong's Striking water-clock was named for its distictive day and night time announcing system. Its time announcing system generates acoustic and visual signals for the twelve double hour, and combinations of two different acoustic signals for the five night watches, The mechanism of this signal generation system is triggered by a copper ball which is mechanically digitized time keeping signal, and is generated from the water clock. The time announcing system consisted four parts: 1) the mechanical amplifier which changes small copper to heavy steel ball, 2) day time announcing system, 3) night time announcing system, 4) sounding mechanism. The time announcing system of King Seong's Striking Clepsidra is remotely related to the Arabic clock system, however, it does have world-widely distictive mechanisms of its era, such as mechanical amplifier, self-weight rachet mechanism, and resetable mechanical computer etc.

Confucianism and Buddhism were compatible in the period of Goryeo Dynasty. And then, the rulers worshiped Confucianism and repressed the religious activity of the Buddhist monk in the early years of the Joseon Dynasty. But King Sejong planed to bring reconciliation between Confucianism and Buddhism. Especially on the ceremonies of mourning and sacrificial rituals, he always performed the two religious style. The reason of sticking to his amicable consciousness is as follows. Firstly, he thinks that both the theory of Confucianism and the religious spirit of Buddhism are very important for the building up the foundation of his Dynasty. Secondly, his mind has been of a same faith cure on the incurable disease. Therefor, when the Royal family is taken ill he must pray to Buddha for recovery from the first stage. Thirdly, he regards social conditions to be the most important and respect for man's life and dignity for the purpose of beneficent administration. But Joseon's government line was the anti-Buddhist policy. So, the policy came in the wake of a debate among King Sejong and Confucian government officials. However his harmonious mind was unchanged between Confucianism and Buddhism. After all, in the last phase of his life he was deeply religious on Buddhism. I think that King Sejong's amicable consciousness could make a contribution to overcome religious conflicts and to create a new political cultural form in the modern society

In accordance with Madrid and Kyoto Protocols, a 10kw wind turbine installed about 625m away from the King Sejong Station in the Antarctica has been in operation successfully. The current location of the wind turbine has different geographic surroundings from the previous candidate site considered in 2005 and that makes re-evaluation of wind resource at the current site including geographic effects necessary. Especially, strong wind flow derived by steep and complex terrain is dominant in the Antarctica so that computational flow analysis is required. The wind rose measured at the previous and current installation location are identical with strong meteorological correlation but prevailing directions of wind power density are different because of local wind acceleration due to complex terrain. Numerical analysis explains which effects brings this discordance between the two sites, and a design guideline required for additional wind turbine installation has been secured.
