Rehabilitation and retrofitting of structures designed in accordance to standard design codes is an essential practice in structural engineering and design. For steel structures, one of the challenges is to strengthen the panel zone as well as its analysis in moment-resisting frames. In this research, investigations were undertaken to analyze the influence of the panel zone in the response of structural frames through a computational approach using ETABS software. Moment-resisting frames of six stories were studied in supposition of real panel zone, different values of rigid zone factor, different thickness of double plates, and both double plates and rigid zone factor together. The frames were analyzed, designed and validated in accordance to Iranian steel building code. The results of drift values for six stories building models were plotted. After verifying and comparing the results, the findings showed that the rigidity lead to reduction in drifts of frames and also as a result, lower rigidity will be used for high rise building and higher rigidity will be used for low rise building. In frames with story drifts more than the permitted rate, where the frames are considered as the weaker panel zone area, the story drifts can be limited by strengthening the panel zone with double plates. It should be noted that higher thickness of double plates and higher rigidity of panel zone will result in enhancement of the non-linear deformation rates in beam elements. The resulting deformations of the panel zone due to this modification can have significant influence on the elastic and inelastic behavior of the frames.

The transcriptions of Buddhist sutra in the Goryeo Dynasty are more elaborate and splendid than those of any other period and occupy a very important position in Korean bibliography. Among them, the transcriptions made on indigo paper show decorative features that represent the dignity and quality that nobles would have preferred. Particularly, during the Goryeo Dynasty, a large number of transcriptions were made on indigo paper, often in hand-scrolled and folded forms. If flexibility was not guaranteed, the hand-scrolled form caused inconvenience and damage when handling the transcription because of the structural limitations of the material that is rolled up and opened. It was possible to overcome these shortcomings by changing from the hand-scrolled to the folded form to obtain convenience and structural stability. The folded form of the transcription utilizes the same principle as the folding screen, so it is a structure that can be folded and unfolded, and it is made by connecting parts at regularly spaced intervals. No matter how small the transcription is, if it is made of thin paper, it is difficult to handle it and to maintain its shape and structure. For this reason, the folded transcription was usually made of thick paper to support the structure, and the cover was made thicker than the inner part to protect the contents. In other words, the forded form was generally manufactured to suit the characteristics of maintaining strength by making the paper thick. Because a large amount of indigo paper was needed to make this type of transcription, it is assumed that there were craftsmen who were in charge only of dark dyeing the papers. Usually, paper dyeing requires much more dye than silk dyeing, and dyeing dozens of times would be required to obtain the deep indigo color of the base of the transcription of Buddhist sutra in the Goryeo Dynasty. Unfortunately, there is no record of the Goryeo Dynasty's indigo blue paper manufacturing technique, and the craftsmen who made indigo paper no longer remain, so no one knows the exact method of making indigo paper. Recently, Hanji artisans, natural dyers, and conservators attempted to restore the Goryeo Dynasty's indigo paper, but the texture and deep colors found in the relics could not be reproduced. This study introduces the process of restoring indigo paper in the Goryeo Dynasty through collaboration between dyeing artisans, Hanji artisans, and conservators for conservation of the transcription of Buddhist sutra in the late Goryeo dynasty, yielding a suggested method of making indigo paper.

The praying sentences of the script of Saddharmapundarika-sutra NO.5 which was made by prayer Bang-Ui, prince Ik-An, was investigated and the cover painting, Byonsangwha(Buddha's preaching painting), and letter style written in the script were discussed in this study. The cover painting on the script is known to be followed to the style of the cover painting as shown in a set of 7 rolls of Saddharma pundarika-sutra of the Horim Museum collection. It is not so difficult to say that the characteristics of cover painting of the script would be suceeded to those of scripts of the end of Koryo and the early Choseon Dynasty. Lotus and its surround was decorated with arabesque figure whose stems were drawn with golden paste and the arabesque figures were done with silver paste. However, for the expression of lotus and arabesque pattern the special feature of drawing style that was originated from the end of Koryo Dynasty to draw the outline with broad line and/or the hardness of drawing line became much more deepened than ever. It is not different to think that this characteristics should be those of Choseon Dynasty. On the Byeonsangwha(buddha's preaching painting) the painting of scattered flowers on stairs of Sumera-Mandala and the scheduled clouds (underseen from heaven) were as similar as to the Byeonsangwha style of the end of Koryo and the early Choseon Dynasty. However, the image of Shakyamuni and/or the halo(光背) is nearly same as the characteristics shown on the Beonsangwha of Saddharma pundarika-sutra of Nesosa' collection, a set of seven rolls which was completed in the 15th year of king Taejong(AD 1415). It is apparent that these characteristics are those of Choseon Dynasty. After king Chungsean in Koryo Dynasty, letter style of Chao Meng-Fu was shown in the script of late Koryo Dynasty as a new letter style.

Four volumes of the script of the Avatamska Sutra written with golden paste on dark blue papers manufactured in Koryo Dynasty which are collected or deposited in every museum of Japan show specific features on their cover paintings. In general 3 or 4 lotus flowers are wound by arabesque patterns in zigzag on the cover paintings of Koryo scripts, whereas 10 lotus flowers painted with golden paste on the 4 volumes of these scripts are same in their style. Though there is no prayer sentences in 4 volumes of the script, it is possible to know that they should belong to a set of 80 Avatamska Sutra by the results of above studies. In this study the contents of Byunsangwha of the script of 4 volumes of the Avatamska Sutra were discussed at first and their manufactured era should be postulated by the results of style analysis of cover paintings and Byunsangwha. First thing that saint hair of Buddha was painted with cobalt color is same as that of Byunsangwha of Munsuchoisangsungmusenggebueob prayed in Tejeong 3rd year, king Chungsuk 13th year(AD 1326). Second thing that the beads in topknot of saint hair and lips were painted completely with pink color, and ears, face outline as well as bosom outline disclosed through monk's cloth were also painted with pink color, furthermore the last thing is that Buddha's face was coated with golden paste. All of these things are same as shown in the characteristics of Byunsangwha of the scripts of Kanezawa Daishoji, Matsue Tenrinji and Haga Tera collection in Japan. However, since the cloud pattern style of Byunsangwha of the script is similar to that of the Byunsangwha manufactured in reinstatement era of king Chungsuk, it is possible to say that these 4 volumes of script should be manufactured in the reinstatement era of king Chungsuk.

The purpose of this article is making investigation of the principal composition of the twin-pagodas in Buddhist temple through ornaments of a case preserving relics of Buddha in the east and west pagodas of Gameunsa temple. This research has an important meaning in clarifying that the concept of placement two Buddhas together with lotus sutra, which was only applied to Bulkuksa temple, has been extended to Gameunsa temple. And this observation gave us a clear explanation for the principal composition at the twin-pagodas in Buddhist temple plans. The author obtained the following conclusion from this article : The cases preserving relics of the Buddha for the west and east pagodas are globally in similar form as the type of a royal palace. But the different points between eastern and western can be seen on the existence of Buddhist statues on the base floor, set-up of the gate at railings, and 4 lion statues at a coner of the base floor. In the western pagoda, there are Buddha statues above the base-floor of the cases preserving relics. These Buddha statues are composed of a boy monks and angels with playing music for the praise of the Sakyamuni Buddha lecturing the Lotus sutra at YoungChui Mountain. On the other hand, in the eastern pagoda, Buddha statues on the cases preserving relics are composed of a the Four Devas and monks as a defending God of the nation of Buddha. In the eastern pagoda, one can see something that does not exist in the western pagoda, which is a gate located in railing of a case preserving the relics. This gate described the scene of the Sakyamuni Buddha entering into the pagoda of 7 treasures. In a corner of the case preserving relics in the eastern pagoda, there is another thing which does not exist in the western pagoda. This is a sculpture of a lion which symbols the seat of Lion supporting the Buddha in the Dabotap(the pagoda of 7 treasures). When we observe the form and structure, the descriptions at the railings, the gate, the shrine, the statue of a lion, and the accessories in jewelries, at the cases preserving the relics in the eastern pagoda, one can realize that they have the same combination structures between the ones at Dabotaps in Bulguksa temple and those in China as well as in Japan, all of which represent the Gyun-Bo-Tap-Pum of Lotus Sutra. Among the distribution rules in the twin-pagodas in Buddhist temple, the application of the ideal of lotus was known to be effected only to Bulguksa temple. But from the result of the present article, it is more clearly proved by applying the Gameunsa temple that the distribution theory in the twin-pagodas in Buddhist temple was in fact based on the ideal of lotus.

This research paper has examined the question of the year of the publication of the wood block print, Mukujeonggwang Dae Darani Gyeong(Pure light Dharani Sutra). Published in Korea sometime before 751, it is known to be the oldest existing document printed with wood blocks in the world. Recently, a Chinese scholar claimed that this sutra was translated into Chinese in 701 and printed in Reoyang, China, in 702. These claims have lead to international symposiums and research papers on the Mukujeonggwang Dae Darani Gyeong. However, although diverse opinions and research were presented by various scholars, they all seem to be far fetched and do not answer the essential question of the sutra. The evidence in historic records shows that the translation into Chinese was done in 704 and not in 701. After it was translated into Chinese, it came to Korea and was printed with wood blocks. When Sokkatap was built in 751, a copy was placed in the pagoda. Moreover, the inscription on the sarira casket states that the construction of the pagoda was based on the theory of Jotapsasang contained in the sutra. Thus this proves that Mukujeonggwang Dae Darani Gyeong had to have been printed before 751.

The chrysanthemum vine pattern box from the Goryeo Dynasty expresses in great detail the representative features of Goryeo Dynasty lacquerware with mother-of-pearl, such as engraving patterns on the surface of fine mother-of-pearl, expressing vine stems using metal wires, and twisting metal wires to form the boundaries of each patterns. While the lacquerware with mother-of-pearl that remains today from the Goryeo Dynasty has the form of a sutra box and a box with lid, the chrysanthemum vine pattern box that is the subject of this study is in the shape of a box with a separate lid and body, making it difficult to estimate the purpose of production or the stored contents. In this study, we attempted to confirm the formative characteristics of the chrysanthemum vine pattern box in order to confirm its original form, and to investigate its structure and production technique through X-ray transmission. In addition, we attempted to identify the use and production purpose of the box by classifying and comparing the previously known lacquerware with mother-ofpearl from the Goryeo Dynasty by type. As a result of the investigation, fabric was confirmed the bottom of body and inner box through X-ray images. Through this, it was confirmed that the 'Mogsimjeopichilgi'(wooden core grabbing fabric technique) of wrapping the object with fabric was used. And through wood grain, it was possible to confirm the wooden board composition of the part presumed to be the restored part and the part presumed to have had existing Jangseog. In addition, it was confirmed that the joints were connected in a Majdaeim(part to part). Based on the survey results, a total of 14 pieces, including 9 Sutra boxes, 3 boxes, and 2 small boxes, that remain from the Goryeo Dynasty were classified by type and examined for similarity. Among them, there is a "Chrysanthemum Vine Pattern Sutra Box" from a private collection in Japan, a "Black Lacquered Chrysanthemum Arabesque Bun Sutra Box" from the Tokugawa Art Museum, a "Sutra Holder" from the British Museum, and a "Small Box with a Mother-of-Pearl Chrysanthemum Vine Pattern" from a private collection in Korea. The pattern composition of five points was most similar to the subject of this study. As a result of comparing the damage pattern, formative characteristics, and structural features of each part, it is presumed that the sutra holder in the British Museum was transformed into its current form from the original the chrysanthemum vine patterned box. Lastly, in order to confirm the purpose of production, that is, the use of this box, we investigated examples of Tripitaka Koreana printed version produced at a time similar to the social atmosphere of Goryeo at the time. Following the Mongol(元) invasion after the Goryeo military regime at the time, sutras appeared to pray for the stability of the nation and the soul of an individual, and with the development of domestic printing and paper in the 13th century, it gradually coincided with the transition from a scroll to a folded form, and the form of a box changed from a box. It is believed that the storage method also changed.

This paper is bibliographical study on Chonshin-sarikyung(全身舍利經 sutra scroll) which is owned by Sungbo museum Woljung-sa(月精寺) in Odae-san(五臺山). Through the investigation with documents and other historical materials in relation to the history of Woljung-sa, I found new prospect that Elder Yuyun of Suda-sa changed name of Woljung-sa at the middle of 13th century. Therefore, as it is considered that construction of Palgakgucheungsuktab(八角九層石塔 Octagonal Nine-storied stone Pagoda) and completion of Chonshinsarikyung were closely related to the rebuilt of Woljung-sa, it is proved that Palgakgucheungsuktab and Chonshin-sarikyung had been completed at this rebuilt period.

Through scientific analysis, this study identified the material characteristics of metal foil decorating the border line and knotting of the National Folklore Cultural Heritage 'Pouch for the Sutra Embroidered with a Sun and Moon Design'. Through Scanning Electron Microscope-Energy Dispersive Spectroscopy results, it was estimated that silver (Ag) and sulfur (S) were present in the metal foil, and silver leaf was also attached to the medium. S may discolor Ag from yellow to black depending on its concsentration and contact time. Yellow color could not be identified in metal foil at present. But there existed an example of the preparation of a gold-colored flat silver thread; therefore, further research is needed to estimate the original color. The lamella was reddish brown on the back. Aluminum, silicon, and iron were also detected and were the main components found in red soil. This is believed to be the red adhesive in traditional flat gold thread and is considered to be an adhesive-related component of the metal foil. From the gas chromatography mass spectrometry results, the adhesive component was confirmed to be animal glue.

The aim of this study is to explain characteristics of Maitreya and Maitreya belief from a point of view that 'Jeungsan is the very Maitreya(甑山卽彌勒)'. In 『Jeon-gyeong』, Maitreya is mentioned several times. Thus, new religions of Jeungsan of Daesoonjinrihoe take 'Jeungsan is the very Maitreya' belief for truth. Due to the fact that characteristics of Maitreya are so multi-layered and complicated, it is necessary to explain clearly what kind of feature Maitreya has in 『Jeon-gyeong』. If believing and following 'Jeungsan is the very Maitreya' without clarifying it, they will be faced with a problem that they regard Jeungsan of Supreme being of the Ninth Heaven as one of Maitreya and take its belief for truth. Furthermore, with respect to the characteristics of 'Jeungsan is the very Maitreya' belief, while believing in Mireukasaeng, longed-for Millenarian movement by people through Messianism and Mireukasaeng belief is found in Daesoon Thought, whereas there is a need how to understand the point that we cannot finped Messianism and Millenarian movement in Daesoon Thought. To solve this problem, I draw a conclusion that 'Jeungsan is the very Maitreya' in 『Jeon-gyeong』 has to be understood with two meanings by four demonstrations. First of all, the people perceived late Joseon dynasty as the age of decadence but Maitreya's divinity which is desired by the people is not divinity of Maitreya Sutra(Mileuggyeong). Maitreya's divinity is reflected in the people's cherished desire and it is newly created as the Messiah. Thus, the idea of Jeungsan being the very Maitreya was developed in a way that the people desired the Messiah, encompassing this inclination. That is the Messiah of the people and the divinity of Jeungsan. Although Jeungsan as Supreme being of the Ninth Heaven satisfied the people's desire, it shows a different way to salvation from the way in Maitreya Sutra(Mileuggyeong). It is 'the Great Reordering of the Universe' and 'the Great Reordering of the Three Realms'. Reordering in Jeungsan shows that divinity of Jeungsan is not limited to the people's Messiah. In other words, divinity of Jeungsan is established as The Messiah, surpassing divinity of Maitreya Sutra(Mileuggyeong). And following statements prove this divinity of Jeungsan. Jeungsan's emphasis is not only the people's desire and the Gods' appeal. Jeungsan's emphasis is that only does Supreme being of the Ninth Heaven correct heaven and earth, which is the Gods' appeal. Therefore, 'Jeungsan is the very Maitreya' belief embraces the people's Messianism and at the same time it runs with he Gods' appeal. Thus, Reordering through the Great Reordering of the Universe and the Great Reordering of the Three Realms builds up a new ideal world.
