The position of the people who participated in the Bapyo Ritual held in the reign of King Sejong and the corresponding costumes were examined. The king, who was the executive body of the ritual, wore Myeon-Bok, a court dress, and Myeon-Bok was Gujang-Bok made of Jang-wha on Guryu-Pyeongcheongwan. Crown princes, royal families, and government officials wore Oryang-Gwan and Jekraeui, which were Jobok. The crown princes' Joboks were changed from Oryang-Gwan to Wukryang-Gwan in the dynasty year 10 of King Sejong, and in the year of King Munjong's accession, Myeon-Bok was received, and after King Danjong, the crown princes wore Palryu-Pyeongcheongwan and Chiljang-Bok. Diplomats and Jongsagwan who were the envoys wore Sangbok. A Sangbok worn by the diplomat was Samo with Danryeong, Seo-Dae, and Hyeopgeum-Hwa, and a Sangbok worn by Jongsagwan was Samo, Danryeong, Heukgak-Dae, and Heukpi-Hwa. Byulgam, who served as an attendant to the king in the king's close quarters, wore Gongbok and Sangbok. Gongbok consisted of Ja-Geon, Danryeong and Heukpi-Hwa, and Sangbok consisted of orange color Cho-Rip, Jikryeong, Joa, and Heukpi-Hwa. The person holding San, Gae , Sujeongjang, and Geumwolbu wore Ja-Geon and Cheong-Ui, and Seon wore Pimoja and Hong-Ui. Siwigun wore armor and helmets equipped with weapons. Among court musicians, Aksa's costumes consisted of Bokdu, Bigongbok, Geumdonghyeokdae, Bibaekdaedae, and Opiri, and Aksaeng's one composed of Gaechaek, Bisuransam, Hyupgo, Mal, Maldae, and Opiri. As a result of the above, the process of ceremonial clothes becoming uniform clothes in the reign of King Sejong was confirmed. The king and lower-ranking officials such as crown princes, government officials, diplomats, Byulgam, armies for ceremonial weaponry, and court musicians participating in the Bapyo Ritual wore the highest grade of ceremonial clothes for each class. King Sejong had repeated discussions to build a nation based on Confucianism, and arranged each rite and corresponding costume, and the Bapyo Ritual costume was also systematically prepared for each position. The ceremonial clothing organized during the reign of King Sejong was regulated in Yejon and became the basis for continuing to the late Joseon Dynasty.

Kim Su-On(1409~1481) was a editor in King Sejong's times who worked on the publication of "Euibangyoochui(醫方類聚)" and other major publications led by the royal family. This paper will review the works of Kim Su-On based on the medical background of early Joseon Dynasty and the medical book-reading officer system, and also evaluate his contribution to the development of medicine in early Joseon Dynasty, factoring in his life, ideas, and literary talent. By looking at the life of Kim Su-On, we can understand the role of Confucian doctors(儒醫) in the early Joseon Dynasty, how Confucian scholars who were learned in medicine supervised the compilation and correction of "Euibangyoochui(醫方類聚)". Especially, from the poetry of "Sikujip(拭疣集)", contents regarding the proofreading of "Euibangyoochui(醫方類聚)" between Im Won-jun and Kim Su-On shows the publication process of "Euibangyoochui(醫方類聚)" at the reign of King Sungjong. His outstanding achievements are largely due to the medical book-reading officer system implemented around the time "Euibangyoochui (醫方類聚)" was published. The medical book-reading officer system aimed to increase the knowledge of various matters for the civil service bureaucrats, allowing them to become high-ranking officials in the fields of technology. Its another purpose was to compile specialty publications. Many of the civil service bureaucrats who participated in the medical book publications arranged the theoretical basis of medicine and modified experience medicine to a new medical system. The first edition of "Euibangyoochui(醫方類聚)" at King Sejong's reign collected vast medical information into 365 books. Then it was corrected during King Sejo's reign then finally completed and published at King Seongjong's reign. During this period, the experience medicine inherited from Goryeo Dynasty was reestablished into a new form of theoretical interpretation.

Raw soy sauce and raw soy sauce added with several Maillard reactants (glucose, xylose, glycine), preheated or unheated, were stored under aerobic or anaerobic conditions to investigate the effect of oxygen on the browning of soy sauce. All experimental groups, except xylose-added groups, stored under aerobic condition browned about 2.5 times as much as those stored under anaerobic condition. Soy sauce added with xylose stored under aerobic condition browned about 1.5 times as much as that stored under anaerobic condition. Contrarily, there have been no consistent differences in the browning except the initial 10% difference between preheated and unheated samples, implying that biological (microbiological and enzymatic) browning was not important in the browning of commercially brewed soy sauce.

We study the manufacturers of the astronomical instruments invented as part of the so-called Ganui-Dae (astronomical platform) project in the reign of King Sejong (1418-1450) of the Joseon dynasty. The main purpose of this project was to compile the Chiljeongsan-Naepyeon, a Korean calendar, that lasted for 5.5 years from 1432 to 1438. Through this project, a total of 17 astronomical instruments such as the armillary sphere, celestial globe, and auto-striking clepsydra were developed. It is generally known that most of them were manufactured by Lee Cheon (李蕆, 1376-1451) and Jang Yeong-Sil (蔣英實, fl. 1423-1442). In this study, we investigate the accounts of the Veritable Records of King Sejong, Munjong, and Sejo, focusing on the inscription written out to memorize the completion of the Ganui-Dae project. We found that at least 12 persons took part in manufacturing the astronomical instruments of the Ganui-Dae project. Lee Cheon was involved in the production of four instruments, while Jang Yeong-Sil was involved in two; therefore, it seems that the achievement of Jang Yeong-Sil was overestimated. We also found that Jeong Cho (鄭招, ?-1434) was a scientist and Lee Cheon was an engineer in the early phase of the Ganui-Dae project, while King Sejong and Yi Sun-Ji (李純之, 1406-1465) played major role in the late phase. According to our study, King Sejong and Yi Sun-Ji were involved in the production of at least seven and five instruments, respectively. In conclusion, we believe that this study will be helpful to understand the practical manufacturers of the astronomical instruments invented during the Ganui-Dae project in the Joseon dynasty.

Environmental monitoring analysis were analyzed for the period from 1988 to 2007 near King Sejong Station. Extreme environment structure behaviors(Marine Biology Lab.) were evaluated using monitoring sensors developed commercial sensors. Also when installing the sensors ambient environment of the King Sejong Station, to analyze the measured data and the comparative behavior of the structure were analyzed. As a environmental monitoring analysis result at King Sejong Station temperature, sensors were installed to withstand about $-25.6^{\circ}C$ or less and 49.5m/s. They were needed that the height of 225.0cm or more to be installed during the installation. For several monitoring sensors used in Antarctic, temperature, snow and strong winds were very sensitive to the atmospheric environment. Quite often a camouflage(animals and humans) would make it necessary to provide housing for monitoring sensors. Therefore, protection system developed for these sensors were to protect the sensors and data logger. Protection system the newly developed, is economical, easy to install even in harsh environments. Based on the measurement result of the one year, consider electrode applicability of the protection system, it was confirmed that the behavior of the structure is also predictable.

The purpose of this paper is to inquire into the significance of Euibangyoochui, Sejo Edition. One cannot study Euibangyoochui, Sejo Edition firsthand since it does not exist today. Instead, this writer looked into the process by which the Sejo Edition had been proofread and the historic figures who led the proofreading process. The quantities of the Sejong Edition and Sejo Edition have been compared, of which the meaning has also been studied. 1. The compilation of Sejo Edition began in 1459(5th year of Sejo), the year King Sejo entrusted the work of proofreading of Euibangyoochui to Yang Seong Ji. This was not a continuance from the work of King Sejong, but a whole new business ignited by the will and necessity conveyed by King Sejo himself. 2. King Sejo regarded medicine important and emphasized its practicality. The fact that the 365 volumes of the Sejong Edition was reduced to 266 volumes reflects the emphasis put on practicality. 3. Yang Seong Ji, who led the proofreading process, played an important role in managing state documents from the time of King Sejo. His compilation, Euibangyoochui, Sejo Edition, is a work that can be discriminated from its Chinese counterpart in that it had been proofread.

Objectives : Doctors are obviously one of the most interesting subject in medical history. Doctors are who treat patients and disease and the authors for medical records or books. Especially doctors in traditional medicine mostly tried to write medical books for new idea or their esperiences or leave their medical records for treatments, medication, prescription and so on. Therefore, many researchers have explained Korean or Chinese medical history of traditional society through those books or documents rather than doctors themselves. The Annals of the Joseon Dynasty has massive records for history, politics, society, culture, etc. Relating to medical history in traditional Korean medicine, there are ceveral researches about disease of King, disease itself, the methods of treatment and so on, through The Annals of the Joseon Dynasty. However, there are few on activities of many doctors in The Annals of the Joseon Dynasty. Methods : I tried to find out the names who had some roles of medicine in The Annals of King Sejong out of The Annals of the Joseon Dynasty. I could get 35 doctors and browsed 35 doctors in The Annals of the Joseon Dynasty again. Finally, I could have lots of articles from The Annals of the Joseon Dynasty related to 33 doctors(2 dontors had no records about medicine even they were doctors). Results : I categorized 2 ways of those articles; medical activities, non-medical activities. For medical activities, I got subcategories for medical activities; medical maltreatment, treatment for King, royal family, bureaucrat, ambassador. I also got subcategories for non-medical activities; publishing medical books, ambassador as a doctor, medical training, things related to hot spring, food therapist, veterinarian. Conclusions : Medical history of Joseon Dynasty in Korean medical history has somehow been recorded by medical books such as Hyangyakjipseongbang, Euibangyuchwi, Euilimchwalyo, Dongeuibogam, Jejungsinpyeon, Dongeuisusebowon, etc. So I have concerned that there are massive records on doctors activities in The Annals of the Joseon Dynasty and tried to focus on their various activities through this research.

A severely cold weather condition of King Sejong Station, Antarctica becomes a very severe condition for an installation/operation of wind generation system. When the existing wind generation system works, it may cause a damage and destruction of wind generation system and can bring about big problems in terms of the power quality. Accordingly, it is essential to obtain technologies for the installation and operation of small wind generation system for the polar region's wind generation, and to assess and demonstrate the performance in the severely-cold environment and the polar wind generation system's development, supplementation, alteration. Also, as the available power of King Sejong Station, Antarctica, the diesel generator has been mainly used, and the wind generator has been used in the hybrid form. Wind generation and diesel generation has the different load following control each other. In the wind generation, the generated power very rapidly changes according to the change of the velocity of the wind. On the other hand, the diesel generation shows very gentle change in the velocity of output. Therefore, the study is intended to analyze the 10kw small wind generator-diesel generator's power quality of King Sejong Station, Antarctica, which is the hybrid system installation area.

Since the operation of the King Sejong Station (KSS) started in Antarctic Peninsula in 1989, there have been continuous efforts to perform the observation for the upper atmosphere. The observations during the initial period of the station include Fabry-Perot Interferometer (FPI) and Michelson Interferometer for the mesosphere and thermosphere, which are no longer in operation. In 2002, in collaboration with York University, Canada, the Spectral Airglow Temperature Imager (SATI) was installed to observe the temperature in the mesosphere and lower thermosphere (MLT) region and it has still been producing the mesopause temperature data until present. The observation was extended by installing the meteor radar in 2007 to observe the neutral winds and temperature in the MLT region during the day and night in collaboration with Chungnam National University. We also installed the all sky camera in 2008 to observe the wave structures in the MLT region. All these observations are utilized to study on the physical characteristics of the MLT region and also on the wave phenomena such as the tide and gravity wave in the upper atmosphere over KSS that is well known for the strong gravity wave activity. In this article, brief introductions for the currently operating instruments at KSS will be presented with their applications for the study of the upper atmosphere.
