Jade, which is a kind of stone, with its transparent body, lustrous and bright character, But jade is not the only fair stone. There are three kinds of jade objects 1) tallies used in the court. 2) ceremonial jades. 3) ordinary jade for decoration, for inlaid work and for burial. Among the ceremonial jade, the most important were the "liu jui" and "liu ch′i." The former was supposed to be held by people in the court as symbols of their authority : 1) "then-kuei(鎭圭)" for the emperor. 2) "hang-kuei(恒圭)" for a duke, 3) "hsin-kuei(信圭)" a marquis. 4) "kung-kuei(躬圭)" for an earl, these "kuei" were alike in shape, but differed in size. 4) "ku-pi(穀璧)" for a viscount. 5) "p′u-pi(蒲璧)" for a baron, "pi(璧)" differed in decoration but were alike in shape. "Liu ch′i(六器)" were ceremonial objects used by the emperor in worshipping Heaven, Earth, and the Four Directions : "ts′ang-pi(倉璧)," greenish jade disk, used in worthipping Heaven "huang-tsung(黃琮)," yellow jade cylinder, used in worshipping Earth ; "cuing-kuei,(靑圭)" blue jade tablet. used in worshipping the East : "chih-chang(赤璋)," red jade tablet, used in worshipping the South : "hsuan-huang(玄璜)," black crescent, used in worshipping the North. Five kinds of tallies were "chen-kuei(鎭圭)," "yenkuei(琰圭)," "yuan-kuei(玩圭)," "ku-kuei(穀圭)." They were used to console people during disaster, to subjugate an official who had committed a crime, to reward a prize to an official for his merit or good conduct, to arbitrate disputes between high officials, to marry princess. and to dispatch troops. Since the west wei(西魏), Kuei and Hole were made of Ivory, wood and bamboo, who had ivory for fifth grade and wood and bamboo for under sixth grade. After Eastern Chou, all officials beginning to had kuei hole. symbol of Authority. and his wives. After Dang dynasty, Japan is the same. In korea. After king Bupheung in ancient and South(unification) Silla, North Kingdom Bohai, Koryo, and Chosen dynasty had ceremonial jade, Kuei and Hole.

This study aims to investigate the role and function of costume in the ancient society by analyzing the jade decorations, 'Gui', 'Bi', and 'Hwang,' recorded in "Zhouli". The method of study consisted of researching the record book "Zhouli" and comparing the antiquities with the images of the jades. Firstly, the jade decorations were different depending on class. The class system in Zhou dynasty was made up of 6 grades - emperor, duke, marquis, count, viscount, and baron. The jade decorations used by people in these grades were called 'Gui', 'Bi', and 'Hwang'. Secondly, this study grasped the system of 'Gui', 'Bi', and 'Hwang.' It identified 7 types of duties by matching the decorations on the jade to specific institutions. 'Gui', 'Bi', and 'Hwang' played a huge role in forming and maintaining to order and system during the chaotic Zhou dynasty. In addition, it became an essential part of understanding status, society, and political structure within a family power structure.

계통연계형 태양광 발전시스템은 계절별 전력수요의 변동이 많은 경우에 첨두전력 삭감의 한 방안으로 고려된다. 본 시스템의 발전효율을 증가시킬 수 있는 방법으로는 근본적으로 태양전지 자체의 변환효율을 증가시키는 방법과 제어관점에서 일사량과 태양전지 표면온도에 따라 시시각각 변하는 태양전지의 최대출력 점에 시스템의 동작점을 추종하게 하는 최대 전력점추적 (Maximum Power point Tracking, 이하 MPPT) 기법을 들 수 있고 발전 효율을 높이기 위하여 자주 사용되어 왔다. 초기 투자비용을 줄이기 위해 후에 등장한 직류초퍼를 사용하지 않고 MPPT 기능을 구현하는 태양광 발전시스템의 경우에 MPPT 알고리즘은 기존의 방법들을 사용하였고 직류초퍼를 사용하지 않은 태양광발전시스템에 적합한 MPPT 알고리즘의 연구는 없었다. 따라서 직류초퍼를 사용하지 않은 태양광 발전시스템에 적합한 MPPT 알고리즘의 연구가 요구되며 본 논문에서는 초퍼 없는 계통연계형 태양광발전 시스템을 대상으로 기존 MPPT 알고리즘의 문제점을 밝히고 이를 해결할 수 있는 새로운 MPPT 알고리즘을 연구하였다.

In this paper, we study the structure of the Daegyupyo (大圭表, Large Gnomon) of the early Joseon dynasty. A Gyupyo (圭表, Gnomon that is Guibiao as pronounced in Chinese) is composed of a Pyo (表, Biao as pronounced in Chinese) making a shadow and a Gyu (圭, Gui as pronounced in Chinese) measuring its length. It is known that the Daegyupyo with the 40-feet height was constructed between the sixteenth to seventeenth year of the King Sejong reign (1444 - 1445) on the basis of the record of Yuanshi (元史, the History of the Yuan Dynasty). By analyzing historical documents such as Joseonwangjosillok (朝鮮王朝實錄, the Annals of the Joseon Dynasty), Yuanshi, and Jegaryeoksangjip (諸家曆象集, a work written by Sunji Lee), we found a possibility that the Ji (池, a pond) on the Gyu was located in the north side of the Pyo. This structure is different from that in previous studies, but is in a good agreement with that of the 40-feet Guibiao remaining in Dengfeng (登封) of China. Regarding to the Hoengyang (橫梁, cross-bar), we suggest that it was set up by double 5-feet supporting arms apart from the north tip of the Pyo in the radial direction. The 3:4:5 ratio in a rectangular triangle was used to place the Heongyang on the top of the Pyo at a distance of 4-feet (3-feet) in the vertical (horizontal) direction. We also discuss the structural problem when the Hoengyang is positioned apart from the top of the Pyo by supporting arms. In conclusion, we think that this study should be useful in restoring the Daegyupyo of the Joseon dynasty.

This study is made on the royal lady's dress In late Joseon dynasty according to the King Heon-jong and Lady Kyung-bin's Wedding Diary in the year of Jung-mi(1847) and summarised as follows: Girls' full dress was a set of a red skirt, a violet undo. jacket, and a light yellow jacket and a green Gyeon-ma-gi(a kind of top jacket) with he. hair Saeng-meo-ri hanging Do-tu-rak-daeng-gi(a kind of hair ribbon). At the big ceremony, girls wore a green Dang-ui instead of Gyeon-ma-gi. A girl picked up as a royal concubine wore a green Won-sam, which was decorated with gilt letters meaning longevity, patched emblems of gilt letter meaning longevity on the breast and on the back, belted with Bong-dae(a red sash with gilt phoenexes), like a princess's full dress. At the Kyung-bin's installation of Crown Princess and her first greeting ceremony with royal elders, she wore a green Won-sam as a formal dress, which had an embroidered emblem of phoenix, the belt with crystal ornaments, Pae-ok(佩玉), Kyu(圭) of blue jade, Shou(綬) with an phoenix. At a Dong-wrae-yun(drinking ceremony after bride and bridegroom's bowing to each other), she wore the embroidered red Jang-sam as a formal dress. Kyung-bin wore a purple Won-sam with Bong-dae as a full dress for a royal feast. According to the occasions, the same dress was differentiated with ornaments and rotors. Ji-keum-bal was an attire for ordinary ceremony. The attire was equipped with a woven gold green Dang-ui with an emblem of phoenix, a blue gilt underskirt and a red gilt overskirt. No-ui was worn as outdoor clothes. Jang-sam was worn by various classes, so it was differentiated with materials and names according to her class.

조선초기 세종대에 제작하여 사용한 규표를 복원하기위해 '세종실록'을 비롯한 조선시대의 문헌자료를 수집하여 원리와 구조를 분석하였다. 그리고 이를 근거로 1/10로 축소 모형을 제작하고 설계도를 완성하였다. 규표의 구조는 규(圭), 용표(龍表), 횡량(橫梁), 또는 들보), 받침대로 구성되어 있다. 수직으로 세운 막대인 용표의 그림자가 수평으로 놓인 규면에 맺힐 때 눈금을 읽으면 된다. 이때 그림자 중심에 태양의 상을 맺히게 하는 영부를 사용하여 정밀하게 측정한다. 영부는 가운데 바늘구멍을 뚫은 작은 동판을 사용하여 바늘구멍 사진기와 샤임프러그 원리를 이용하여 태양의 영상을 맺히도록 한다.

동아시아에서 규표는 가장 전통적인 천문의기 중 하나였다. 그럼에도 불구하고 고전적 규표는 표의 수직 설치와 유지가 어렵고, 눈금의 시작점이 모호하였으며, 무엇보다도 태양의 표 그림자가 퍼져 관측의 정밀성이 떨어졌다. 이러한 고전적 규표의 단점을 해결하고자 하는 노력의 결과물로 13세기에 횡량형 규표가 개발되었다(민병희 등, 2011). 횡량형 규표는 영부를 사용하여 선명한 횡량 그림자를 얻었다. 영부를 통해 얻은 횡량 그림자는 예리하여 관측의 모호성이 없으며, 동시에 태양의 중심 위치를 관측하는 최적의 천문의기이었다. 대규표는 횡량을 설치하였는데, 이 횡량의 크기는 길이 6자(124.2 cm), 직경 3치(6.21 cm)이었다. 표 기둥 위에 횡량을 올린 것을 얼이라고 하고, 이 얼을 수직으로 설치하는 것이 횡량형 규표의 핵심이었다. 삼점현추법을 사용하여 얼을 규에 수직으로 세울 수 있었다. 삼점현추법을 사용하기 위해 횡량은 길이 5치(10.35 cm), 직경 2푼(4.14 mm)의 철사 3개를 이용하고 있다. 삼점현추법은 단지 횡량을 정렬하는데 만 필요한 것이 아니고, 횡량을 점검하고 진단하는데도 활용되었다. 횡량의 개발은 태양 중심의 그림자길이를 측정하는 천문학적 이점과 더불어 규표의 대형화를 가능하게 하였다. 규표의 적절한 건설 공정과 삼점현추법을 적용하면 이상적으로는 높이에 무관하게 얼을 수직하게 설치할 수 있었기 때문이다. 얼의 크기가 높아질수록 결과적으로 눈금의 분해능을 증가시킬 수 있기 때문에(이용삼 등, 2006) 관측의기의 성능을 향상시킬 수 있었다.

Sacredotal robe(法服) means full court dress. We can't know about the shape of sacredotal robe before Dae-Han Empire(大韓帝國) since there are no remains of it. The study of sacredotal robe for queen have also been made centering around the socredotal robe granted from Ming(明) dynasty and the system of Juck-Eui(翟衣) in Dae-Han Empire. In this thesis I tried to study about the sacredotal robe for queen from King Gong-Min(恭愍王) of Koryeo(高麗) dynasty to the close the Cho-Sun(朝鮮) dynasty by investigating the Literature of Cho-sun Dynasty Chronicles(朝鮮王朝實錄), Ga Rae Do Gam Eui Gue(嘉禮都監儀軌), Sang Bang Jung Rae(尙方定例), Gook Hon Jung Rae(國婚定例), Sok-Orae Eui-Bo(續五禮儀補), and Dae Myung Whe Jeon(大明會典). The first documents on sacredotal robe for queen is regarded as that in the period of King Gong Min., which says that Chil Whee Gu Bong Gwan and Juck Eui of the 9th grade had been given from Ming dynasty. The sacredotal robe for queen in Chosun had been granted from Ming dynasty since the 3th years of King Tae-Jo(太祖) to the 3th years of King In-Jo(仁祖). They were Ju Chui Chil Juck Gwan, red Dae Sam(大衫), Bae Ja(褙子) embroidered with. pheasants on blue silk, and ivory flat baton (笏), which belonged to the court dress for the first class of court lady. When Qing(淸) dynasty succeeded to Ming dynasty, Cho-sun adopted the system of luck Eui which had it's origin in the system of Ming, denying to comply with Chung. But as a matter of fact, the system of sacredotal robe for queen actually used was one which were different from the dress system of Ming and converted into our national ways. In the latter period. of Cho-sun, the system of Bae Ja or Juck Eui were used together until the period of King Young Jo(英祖), and the system of Juck Eui which was written in Gook Hon Jung Rae was continually used from King Young Jo to the close of Cho-sun. It was composed of Juck Eui, Beol Eui(別衣), Nae Eui(內衣), Pe Sool(蔽膝), Dae Dae(大帶), HaPi, Sang(裳), Ok Dae(玉帶), Pae Ok(佩玉), Gue(圭), Mal(襪), Suk, and Myun sa(面紗), The headdress was used in our own ways, not complying with Juck Gwan(翟冠). The color of Juck Eui was red for queen, deep blue for the consort of the crown prince. The color of Juck Eui in DaHan Empire was deep blue, different from that of Juck Eui in Cho-sun. Bo(補) for queen wus embroidered with dragon with five claws and the one for the consort of crown prince with dragon with four claws. The back length of Juck Eui was longer than front about 28cm (1尺), and the front opening was straight down. 51 motifs of a brace of pheasants which were similiar to Bong(鳳) were embroidered on Juck Eui for queen. But we can't find out whether there 31 or 51 on Juck Eui for the consort of the crown prince. The system shows independant aspects, because there are Bo, Myun Sa, Sang, Ha Pi, Beol Eui, and Nae Eui which were not found in the system of Ming. As mentioned above, I have studied on the sacredotal robe for queen. But we can't guess the detail of sacredotal robe for queen, because there are no remains at all. Therefore I expect more study on this.
