A variety of dyes are commercially available today, there is an ongoing need for new chromophoric systems and low-band-gap materials. For example, near-infrared (NIR) emission has received increased attention for applications in bioassays and medicine while NIR absorption is demanded for laser-welding of plastics or efficient blocking of heat rays. Most of the commercially available NIR materials are not suitable for such purposes owing to their insufficient stability. We have developed a novel NIR-absorbing polyaromatic dye. By extending the system of perylenebis(dicarboximide)s along the molecular long axis, we have obtained the higher homologue pentarylenebis(dicarboximide). We have tried to introduce imide functional group to pentarylene in order to increase chemical and thermal stability.

A chronological classification of Sangbok(상복) and Sibok(시복) for officers in Joseon Dynasty is proposed in this paper. The classification results in four distinct periods according to the usage of Sangbok and Sibok as well as their colers and naming: 1) the mixed usage period, 2) the usage-differentiation period, 3) the name-differentiation period, and 4) name-reversal period. During the mixed usage period which lasted until the early 15th century, Sangbok and Sibok were used with no distinction. In the usage-differentiation period, the King Sejong first made a regulation on the use of colors of Dal-lyung according to the occasion and black colored uniforms were used only for daily cabinet meetings. In the 16th century, the names of Sangbok and Sibok began to be used distinctively: Sangbok for formal clothing in black color and Sibok for ordinary clothing in pink color This period is defined as the name-differentiation period in this paper. In the name-reversal period f·hick begun around the 17th century, the usages as well as the colors of Sangbok and Sibok are totally reversed because of some confusions of the understanding on the previous government publications. However, the distinction of formal clothing and ordinary clothing remained.

The personal praying sentence in personal praying scripts of Koryo Dynasty should be very important source for study of Koryo buddhism's history as well as historics, bibliographics and art historics. Especially it would be good source for study of official position in Koryo Dynasty because in the personal praying scripts the prayers expressed their own official position when compared to the official positions presented in Bekguanji(all officer's magazine) in Koryosa(history of Koryo Dynasty). As the characteristic of script is presented in the contents of personal praying sentence, it would be remarkable source for study on the history of buddhism's thought. Through the personal praying sentence it is possible to make clear the hopes of donor and high monks who were the key members for writing praying script. Also study on the personal praying sentences in Koryo scripts would be helpful for understanding the profile of society of Koryo Dynasty.

The purpose of this study was to consider the kinds and features of costume and fabrics of the early Koryo period which are mentioned in the records of costume system, royal presents and diplomatic articles at that time ranging from the reigns of king Gwangjong to king Gyeongjong and to king Seongjong. Findings of the study can be summarized as follows. In the 11th year of king Gwangjong's reign, the official costume system was established, which reflected the royal will to independence as an imperial nation. That system also became the basis of the official wage system in king Gyeongjong's reign. In the reigns of king Gwangjong and king Gyeongjong, the monarch granted official uniforms to persons who passed the state examination, directly connecting with new bureaucrats and strengthening the royal authority. Those uniforms were usually worn at a banquet where the monarch and subjects participate together in the early Koryo period. In the reign of king Seongjong, costume and fabrics were positive means of realizing political Confucianism as they were used for bureaucrats who advanced to official position through the state examination. Records issued at that time explain that the monarch presented costume and fabrics in an effort to getting along with officials and civilians of different classes as the state and the royal authority stabilized. Found in the records released in the reigns of king Gwangjong to king Seongjong, the kinds of costume or fabrics at that time include jikseongeuio, gap, yongeui, seupeui, gyegeum baekcheop, geumeunseon gyegeumpoyok and po. The techniques of manufacturing armors in the early Koryo period were probably advanced since the item was a craftwork presented to the court in the reigns of kings Gwangjong and Gyeongjong. Presumedly, baekcheop was a kind of hemp and po. Koryo's native hemp cloth.

This study analyzed and examined the entries of natural disasters recorded in Samguk-sagi in relation to the natural thoughts. In the ancient Korean view of nature thought the Unified Shilla dynasty surveyed their view on nature in terms of terrestrial upheavals. In the first place, I came to know that the important natural disasters such as droughts, floods, hails, locusts, earthquakes, thunderstroke, storms uprooting trees, tornado etc. recorded in Samguk-sagi have something in common with the entries of natural disasters in the ancient Chinese histories. Accordingly, they interpreted natural disasters in terms of good omens and heavenly punishments. The king refrained from luxurious food and drink, released prisoners or reduced their sentence as a sign of his benevolence. They thought that natural disasters were caused by the heavenly instruction due to lack of virtue on the part of the king. I think that these were acts of ritual on the part of the king as a ruler to fulfill his responsibility for a benevolent administration.

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.
