The yanggwan is a striped headpiece for civil and military officials worn with jebok, a costume for the royal ancestral worship ceremony, or jobok, a ceremonial costume for the courtier. It was called a jegwan when it was worn with a jebok. The geumgwan and jegwan are of the same style but the geumgwan has a gilded band and backside and the jegwan is mostly lacquered. The yanggwan was worn first with the jebok by the officials, both of which were received from the Chinese Ming dynasty in the 19th year of the King Gongmin's reign during the Goryeo period. The royal crown and court clothing system was two grades lower than the standard clothing code of the Ming dynasty of China. In the Joseon dynasty, the oyanggwan worn by the highest grade officials had five-stripes but was later replaced during the Daehan Empire by the seven-striped chilyanggwan used by Ming dynasty officials. Oyanggwans make up the majority of the surviving examples of these headpieces, with the exception of the six-striped yukyanggwan of Chung In-hak (1839-1919), the Minister of Justice, which originated in the Daehan Empire and whose owner is definitively known. The gilt portion of this yukyanggwan is finely engraved in relief with a bird, flower and tendril motif. The yukyanggwan is topped by a decorative bird ornament, called a jeongkkot. EDSS spectrum analysis of the gold plating reveals a composition of 51.32% gold and 10.34% silver. The yanggwan is composed of bamboo, mulberry paper and silk crepe. The black portions are lacquered. The individual yang is made with twisted mulberry paper.

The purpose of this study is to investigate the costumes of the ruling class in the Asuka-Nara Period by looking at the change in the clothing law of the era. During the Asuka-Nara period, various cultures such as Buddhism, architecture, sculpture, paintings, music, and so on were introduced through vigorous exchange with Chosun and Tang. Contrary to the primitive-Kohun Period, the regulation about costumes was enacted as law in the Asuka-Nara Period this fact tells us that there was high interest in clothing. Frequent reorganization of clothing law had to do with the rank system of Japan as well as with the exchange with other countries. The clothing law of Asuka-Nara Period was mostly consisted of the regulations about costumes of the ruling class including the royal family and government officials. The law regulated different coronet and color for the clothing depending on the different rank of the government officials. The more classified the rank was, the more varied color was used. In addition, there was a variety in the costumes system; 2 piece clothing of the Kohun Period was continuously used while new types of clothing were also introduced. The royal family members and government officials wore different types of clothing such as Yebok, Jobok, and Jebok, depending on time, place, or the purpose of occasion. The costumes of this period could be inferred from the analysis of the relics.

In recent years, the usage of fossil fuels has caused problems of climate change and global warming. Because the combustion of fossil fuels is related to the production of greenhouse gases ($CO_2$, $CH_4$, etc.), new technology in the field of combustion is needed in order to handle the crisis of climate change and the global warming. As one of the efforts to reduce the emission of greenhouse gases, the concept of regenerative oxy-fuel combustion for energy efficiency and carbon capture was suggested, In the current study, the development of an industrial regenerative oxy-fuel combustion furnace was introduced, which has been being performed at Korea Institute of Energy Research (KIER).

Jeju island is located in far from main land and has very harsh environment that has formed an unique clothing style as well. In addition, the popular belief has been developed with originality even their clothing.

The shamanism served 18,000 gods are composed to 12 different types of the events for wealth, safety, heath, sadness or thanks. The costumes worn by officiating priests or 'Simbang(shaman)' depend on the occasion of an event, and they are different for male and female performers. The styles of costumes for religious service can be divided into 7 types: Regulation dress(Jebok), Korean full-dress attire(Dopo), Official uniform(Danryung), Military uniform(Gunbok), Formal dress (Durumagi), Casual wears and Special costumes.

The combustion characteristics with variations in synthetic natural gas (SNG) compositions were studied in a lab-scale combustor. The objective of the current study is to investigate the flame stabilization, flame structure, and spectrometry in a non-premixed SNG flame with varying fuel compositions. For the analysis of light emission in SNG flames, we used a spectrometer. As experimental conditions, the fuel jet velocity at the nozzle exit $u_F$ was varied from 5 to 40 m/s and the coaxial air velocity $u_A$ was varies from 0 to 0.43 m/s. The experiments showed that the flame stability increased with the hydrogen component in SNG.
