Fashion magazine advertising is the most excellent source of information in predicting the fashion trend. It plays a pivotal role in setting a direction for the fashion trend in the upcoming season. The purpose of this study was to review by photos of the $pr{\hat{e}}t-{\acute{a}}-porter$ collection shown in LONDON, NEW YORK, MILAN, and PARIS during 2002-2006 A/W and 2003-2005 S/S seasons, being focused on such fashion items published as coat, dress, one-piece, two-pieces(jacket+skirt/pants, blouse+skirt/pants). In the results of this study, designers presented coat(n=144) chiefly, blouse+pants(n=29) were presented few during 2002-2003 A/W seasons. During 2003-2004 A/W seasons one-piece(n=156) was looking bullish, blouse+pants(n=34) were declining. Dress(n=149) was presented mostly, blouse+pants(n=17) was presented few during 2004-2005 A/W seasons. During 2005-2006 A/W seasons coat(n=180) was revived, blouse+pants(n=26) were presented lowly. Therefore designers presented coat(n=605, 28.4%) extremely much during 2002-2006 A/W seasons. Designers presented one-piece(n=109) much, jacket+pants(n=22) were presented few in 2003 S/S. In 2004 S/S seasons one-piece(n=167) was presented vastly different than jacket+pants(n=42). Also one-piece(n=152) was presented mostly, blouse+pants(n=48) was presented few in 2005 S/S seasons. During 2003-2005 S/S seasons one-piece(n=428, 28.2%) was presented most. And designers in these four world fashion centers didn't prefer blouse+pants in A/W seasons and jacket+pants in S/S seasons. Based on the above findings, it could be confirmed that the fashion items trend was almost similar among the four collections of $pr{\hat{e}}t-{\acute{a}}-porter$. The results of this study suggest that the fashion collections are the most reliable information sources for fashion product planning. Lastly, it is hoped that this study will provide for some useful basic data for domestic fashion businesses in producing fashion items.

Hox genes encode transcription factors important for anterior-posterior body patterning at early stages of embryonic development. However, the precise mechanisms by which signal pathways are stimulated to regulate Hox gene expression are not clear. In the previous study, protein kinase B alpha (Akt1) has been identified as a putative upstream regulator of Hox genes, and Akt1 has shown to regulate Gcn5, a prototypical histone acetyltransferase (HAT), in a negative way in mouse embryonic fibroblast (MEF) cells. Since the activity of HAT such as the CBP/p300, and PCAF (a Gcn5 homolog), was down-regulated by Akt through a phosphorylation at the Akt consensus substrate motif (RXRXXS/T), the amino acid sequence of Gcn5 protein was analyzed. Mouse Gcn5 contains an Akt consensus substrate motif as RQRSQS sequence while human Gcn5 does not have it. In order to see whether Akt1 directly binds to Gcn5, immunoprecipitation with anti-Akt1 antibody was carried out in wild-type (WT) mouse embryonic fibroblast (MEF) cells, and then western blot analysis was performed with anti-Akt1 and anti-Gcn5 antibodies. Gcn5 protein was detected in the Akt1 immunoprecipitated samples of MEFs. This result demonstrates that Akt1 directly binds to Gcn5, which might have contributed the down regulation of the 5' Hoxc gene expressions in wild type MEF cells.

Najang was the central Seori, affiliated to the Ministry of War during the Joseon dynasty. The objective of this study is to research the existing authentic Najang costumes from the late-Joseon dynasty by examining factors, such as the composition of the costume, size, and method of creation, and attempt to replicate it. The Leipzig Grassi Museum in Germany possesses an official uniform of Najang from the late-Joseon dynasty, and we visited the museum in May of 2013 to examine it for the study. Written records, or Uigwe, and other pictorial data from the Joseon Dynastry describe the Najang wearing black or navy clothing with white decoration and pointy hats. The most notable characteristic of the Najang uniform is that it has the cotton cords pattern. The hat has a brass ball attached, which was worn with the ball facing the front in the early Joseon Dynasty, and was worn facing the back in the later years. They usually wore black head cloths (Heuk-geon), but would attach feathers on the black hats (Heuk-rip) for special occasions. The Najang uniform preserved in the Leipsiz Grassi Muesim does not exist in Korea. It is made of cotton. The cotton cord pattern of the uniform of Najang was made using single-ply cords and double-ply cords. The hat worn by Najang is in a form of a cone that becomes narrower towards the top or is in a form with wide and open end. It was made of oiled paper covered with hemp, and two circular metal disks were attatched at the rear.

This study is focused on the man's costumes of Sadangpae(the troupe of performers) shown in Gamrotaenghwa (감로탱화) during the late Chosun dynasty. Originally Gamrotaenghwa was used as a painting for a Buddhist praying ceremony, 또Young-ga-cheon-do-je(영가천도제). It shows us the lives of the commoners in those days. Gamrotaenghwa reflects the changes of costume style in the late Chosun period. The early styles of po(포, coat) for male performers in the 17th century were changeui(창의) and dopo(도포), which had the front panels(seop) overlapped deeply and sleeves that got wider as time passed. After the 18th century, Male performers wore a simpler coat such as sochangeui(소창의), which had narrow sleeves and long slits on the both sides. Especially the coats of acrobats were fastened on the center front with buttons. Heuklip(흑립: black hat), somoja(소모자: small cap) and jeonlip(전립: wool hat) were used as hats for the male performers. Originally, heuklip was the hat that represented the noble status: yangban(양반). However, it was popularized among the commoners in the late Chosun period. As time passed on, the heuklip became more popular and its shape also changed. Somoja and jeonlip were shown throughout the entire Gamrotaenghwa. Unlike heuklip, those were common hats for Sadangpae. The costumes of entertainers shown in Gamrotaenghwa were very similar to those of the commoners. However, it seems that there were some differences of the costumes depending on the roles they performed.

최근 들어서 유연 OLED (Organic Light-Emitting Diodes) 소자에 대한 연구가 증가하면서 전통적인 ITO 전극을 대체할 수 있는 전극물질 후보로 그래핀이 많은 주목을 받고 있다. 그 중에 CVD 방법으로 합성된 다층 그래핀(Few layer graphene, FLG)은 실제 상용화되는 소자에 응용이 될 가능성이 높아 많은 연구가 이 방향으로 진행되고 있다. 이 연구에서는 다층 그래핀과 유기물질 사이의 계면을 전자분광학 분석을 이용해 각 분자층 사이의 에너지 준위 변화에 대해 분석했다. 에너지 준위 정렬을 이용하면 각 분자층간의 정공주입 에너지장벽을 알 수 있는데 이 에너지 장벽은 소자의 효율에 직접적으로 연관되는 값이다. 정공 주입층 물질로는 TAPC 1,1- Bis[4-[N,N'-di(p-tolyl)amino]phenyl]cyclohexane (TAPC)를 사용했고, 다층 그래핀과 TAPC층 사이의 에너지 준위 정렬을 분석한 결과 다층 그래핀과 TAPC층 사이에는 ~1.4 eV의 에너지 장벽이 존재함을 확인했다. 하지만 OLED 소자로 활용하기 위해서는 이보다 더 낮은 에너지 장벽을 필요로 하기 때문에 두 물질 사이에 4,4'-bis(N-phenyl-1-naphthylamino)biphenyl (NPB), 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN)을 삽입하여 에너지 장벽을 낮추기 위한 시도를 해 보았다. 그래핀과 TAPC 사이에 중간층으로 NPB를 사용했을 때의 에너지 장벽은 0.55 eV, HAT-CN을 사용했을 때는 0.4 eV로 TAPC만 사용했을 때보다 ~1 eV정도 에너지 장벽을 낮추는 효과를 보여줬다. 이 연구를 통해 다층 그래핀을 OLED 소자의 전극으로 활용할 수 있는 가능성을 볼 수 있었다.

The current study aims to classify types of traditional fur Garments in Jeju into Dusik(hat), dress, Jokui(socks) and accessaries, and examine characteristics of them through demonstrative study focusing on collections of museums in Jeju. Dusik is a kind of hat for protection against the cold, and there are badger leather Gamtaes and cow hair Beonggeojis(fur hats). Especially leather gamtae was used to protect against the cold when people hunted roe deers in Mt. Halla. Beonggeoji was producted in the form of felt with fine hair collected coat-shedding of cows and dogs in spring, therefore it was too warm and practical to be damaged from storm or pressure. Fur coat is a general name of dress made of leather without hair. It is a kind of clothes with a hat worn while taking care of horses and cows. Also people wore dog leather topcoats and cow leather topcoats when they hunted in Mt. Halla. As for Jokui, there are leather Beoseon(socks) made of cow leather, leather shoes in the form of straw shoes, and leather Balle embracing the low half of the body warmly. Accessaries include a rectangular cow leather bag for storing an iron piece for making fire. These traditional fur robs in Jeju not only have practicality for protection against the cold, but also symbolized richness by using leathers of badgers, roe deers, etc. that were previous during that times. Also they used partially cut leather for decoration at the edge.

Most of current bridge decks are made of reinforced concrete and often deteriorate at a relatively rapid rate in operational environments. The quick deterioration of the deck often impacts other critical components of the bridge. Another disadvantage of the concrete deck is its high weight in long-span bridges. Therefore, it is essential to examine new materials and innovative designs using hybrid system consisting conventional materials such as concrete and steel with FRP plates which is also known as composite deck. Since these decks are relatively new, so it would be useful to evaluate their performances in more details. The present study is dedicated to Hat-Shape composite girder with concrete slab. The structural performance of girder was evaluated with nonlinear finite element method by using ABAQUS and numerical results have been compared with experimental results of other researches. After ensuring the validity of numerical modeling of composite deck, parametric studies have been conducted; such as investigating the effects of constituent properties by changing the compressive strength of concrete slab and Elasticity modulus of GFRP materials. The efficacy of the GFRP box girders has been studied by changing GFRP material to steel and aluminum. In addition, the effect of Cross-Sectional Configuration has been evaluated. It was found that the behavior of this type of composite girders can be studied with numerical methods without carrying out costly experiments. The material properties can be modified to improve ultimate load capacity of the composite girder. strength-to-weight ratio of the girder increased by changing the GFRP material to aluminum and ultimate load capacity enhanced by deformation of composite girder cross-section.

This study is a review of Ipsik, the decorative ornaments found on traditional Korean horsehair hats, known as Ipja, which were worn by men in the late Joseon Dynasty. In a broad sense, Ipsik are regarded as men's accessories. Therefore, although this study is limited to Ipja, it is significant in the sense that it delves into one facet of men's accessories in detail. Because the appearance of the horsehair hats was rather mundane, Ipsik and Ibyeong were added as ornaments. During the Joseon period, various types of hat ornaments existed, named Maeksu, Hosu, Gongjagu, Sangmo, Jingdori, Ijeon, Guyeongja and Ibyeong. A person's social ranking and class could be discerned by the materials used in the Ipsik he wore. Jeongja, a decorative accessory used to attach to an official's hat, was institutionalized in the sixteenth year of King Gongmin's reign(1367), during the Goryeo Dynasty, prior to the founding of China's Ming Dynasty in 1368, which indicates that Jeongja were influenced by the Yuan Dynasty. A record in Lao Chi'ta (a textbook of spoken Chinese estimated circa 1346) confirms this fact. Based on a review of literature, we learn that just as with Ongno, Jeongja were imported for use on Jeonrip, a soldier's hat. During the Ching Dynasty, Jeongja were further subdivided and more exquisitely designed. On the other hand, in the Joseon Dynasty, a rule was handed down mandating that a royal prince use gold for his jeongja, officials at third rank or above use silver, and governors, commanders in chief, and officials with the Office of Inspector General and Office of Censor General use jade. Inspectors were permitted to use crystal. Jeongja made of jade were used until the late Joseon Dynasty.
