  • Many organisms are known to survive in icy environments. These include both over wintering terrestrial insects and plants as well the marine fish inhabiting high latitudes. The adaptation of these organisms is both a fascinating and important topic in biology. Marine teleosts in particular, can encounter ice-laden seawater that is approximately $1^{\circ}C$ colder than the colligative freezing point of their body fluids. These animals produce a unique group of proteins, the antifreeze proteins (AFPs) or antifreeze glycoproteins (AFGPs) that absorb the ice nuclei and prevent ice crystal growth. Presently, there are at least four different AFP types and one AFGP type that are isolated from a wide variety of fish. Despite their functional similarity, there is no apparent common protein homology or ice-binding motifs among these proteins, except that the surface-surface complementarity between the protein and ice are important for binding. The remarkable diversity of these proteins and their odd phylogenetic distribution would suggest that these proteins might have evolved recently in response to sea level glaciations just 1-2 million years ago in the northern hemisphere and 10-30 million years ago around Antarctica. Winter flounder, Pleuronectes americanus, has been used as a popular model to study the regulation of AFP gene expression. It has a built-in annual cycle of AFP expression controlled negatively by the growth hormone. The signal transduction pathways, transcription factors and promoter elements involved in this process have been studied in our laboratory and these studies will be presented.

  • Creativity is crucial in designing and producing attractive accessaries and daily supplies as well as art works. Generative design can be a paradigm to be used to obtain novel ideas or motifs for creative design works. This paper introduces a generative design method which comes up with unique ring models using genetic algorithm. It presents how the genetic algorithm works in terms of candidate solution coding, operators, and fitness evaluation function. The proposed method allows the customers to express their personal preference and later the preference to be reflected in fitness evaluation. In the final stage of the proposed method, several ring models are suggested for customers to choose on their own. The chosen ring models can be put into physical rings with the help of a 3D printer because the models are expressed in 3D geometric structures.

  • Background: MicroRNAs are noncoding RNA molecules that posttranscriptionally regulate gene expression. The aim of this study was to determine the role of microRNA-21 in cholangiocarcinomas and its relationship to cholangiocarcinoma RBE cell capacity for invasion and metastasis. Methods: MicroRNA-21 expression was investigated in 41 cases of cholangiocarcinoma samples by in situ hybridization and real-time PCR. Influence on cholangiocarcinoma cell line invasion and metastasis was analyzed with microRNA-21 transfected cells. In addition, regulation of reversion-inducing-cysteine-rich protein with kazal motifs (RECK) by microRNA-21 was elucidated to identify mechanisms. Results: In situ hybridization and real-time quantitative PCR results for patients with lymph node metastasis or perineural invasion showed significantly high expression of microRNA-21 (P<0.05). There was a dramatic decrease in cholangiocarcinoma cell line invasion and metastasis ability after microRNA-21 knockdown (P<0.05). However, overexpression significantly increased invasion and metastasis (P<0.05). Real-time PCR and Western-blot analysis showed that microRNA-21 could potentially inhibit RECK expression in RBE cells. Survival analysis showed that patients with higher expression levels of microRNA-21 more often had a poor prognosis (P<0.05). Conclusions: MicroRNA-21 may play an important role in cholangiocarcinoma invasion and metastasis, suggesting that MicroRNA-21 should be further evaluated as a biomarker for predicting cholangiocarcinoma prognosis.

  • The purpose of this study is to document an unidentified velvet fabric which is located in the Museum. The investigation was conducted by analyzing color, weaving technique. pattern of the study object. To identify the origin of the object, many references about color trends, construction methods and patterns were accessed. Two comparative objects which were dating from 1600 to 1699 in the Museum of F.I.T. were selected since they are similar to the study object. The results of this study can be summarized as follows; (1) The type of this study object is 'cut and voided velvet'. It is obtained establishing the motif as areas of cut pile so as to form a pattern, while leaving other areas of the grounded weave without pile. Two flowers and two tulips with S curved stems are composed as one unit in the vertical direction. (2) The colors used in this study object. which are ivory, smoke blue, medium orange, and yellow. are part of a new trend color in the $17^{th}$ century. (3) The vertical undulating stripe patterns are also of significance in this fabric. They seemed to be contemporary with the serpentine line which was common since the $15^{th}$ century and the vertical stripes pattern which appeared from the $16^{th}$ century. (4) The stylized tulip patterns of this study object began to appear in the early $17^{th}$ century. The stems and leaves of this patterns are less sinuous than the floral motifs of the later $17^{th}$ century. Therefore, the study object is dated to early in $17^{th}$ century because of the color combination. stripes. stylized tulips, leaves. and stems are showing the characteristics of this period.

  • The significant role of colors in fashion design is not enough to emphasize in terms of one of the important design elements and its influences on the behaviors of the people. The purpose of this research is to examine the traditional Chinese colors and its ways of color combinations to appreciate the Chinese culture and its people. The Chinese traditional costume of Ching Dynasty were investigated through historic records, historic nobles, costume accessories and so on. The results of the study were summarized as follows: (1) The Blue was the most favoured color for clothing among men and women during Ching dynasty and various blues in terms of hue, value and intensities were used. (2) The bright Yellow which had been a symbol of Emperor were prohibited being used among people. Though, the late period of Dynasty, the regulation became not to strict and various shades of yellow families were adapted among People. (3) The Red which had been preferred during Ming Dynasty were constantly favoured for the formal wears of auspicious events such as weddings. (4) Dark color groups were loved for the clothing which were used as a ground colors against the flamboyant patterns revealing strong visual effects through value contrast or primary color combinations. (5) The White had a symbol of mourning and there were some intentions to adopt pale color groups such as mint, jade, gray, moon whit,. silver white to make up for white. (6) Contrast color combinations were one of the basic ways of color combination in Chinese traditional costume. Therefore Chinese color combinations has a strong visual effect and easy to draw attention of people by the contrast of the hue, value or intensity of color. (7) Multi-color combinations were another characteristics of Chinese costume in the formal wears which bears many surface designs. The surface decorated with full of motifs, were appreciated by the people expressing their longings and hopes through the auspicious meanings of patterns and striking visual effects of color combinations.

  • The Mural Tomb of Xu Xianxiu(AD 571), a high ranking official in Northern Qi period, is located in Taiyuan, Shanxi province, China. Despite having been raided, it was still discovered to contain over 530 pieces, such as artifacts and murals, in excellent state of preservation. These murals are noteworthy for their high level of detail compared to other murals from the same era, and are important for understanding the historical context of active East-West and Han-Hu cultural exchange in the $6^{th}$ to $7^{th}$ century. The murals of Xu Xianxiu's tomb depict round-collared and narrow-sleeved garments as well as straight collared robes typical of the Xianbei tribe's attire. Notable are the ermine fur overcoat and a headwear with flares on the left and right thought to be unique to the Xianbei. The wife and female servants show female attire of the Xianbei at the time; this attire can be characterized by narrow-sleeved long gowns and asymmetrical flying-bird buns. Despite the anti-Han policy of Northern Qi, influences such as the right sided gathering of the robes and embellished hair styles remain. The procession also depicts the three-cornered headdress and long-tailed hood of the Xianbei men, which have been recorded in documents. The large rounded pearl pattern containing the palmette, the divine animal, and bodhisattva's head motifs show the influence of the Western China [Xi'yu]. Considering that Northern Qi had more active interactions with the three ancient kingdoms of Korea than with the Southern Kingdoms[Nanchao], the findings of this study call for further research on the correlation between the attire of ancient Korea and Northern Qi.

  • In February 1986, a high-school student reported the discovery of fragments of gilt-bronze burial goods on a mountainside behind a village in Ipjeom-ri, Ungpo-myeon in Iksan. The National Research Institute of Cultural Heritage immediately undertook an excavation. Unfortunately, gilt-bronze relics including a band and vertical decorations for a crown, a hat, and shoes had already been collected from Ipjeom-ri Tomb 1 by the student who found them before they could be properly excavated. Also, the interior of the stone chamber of the tomb had been severely disturbed by the time of excavation, making it difficult to identify the precise original locations of the relics within the tomb and hindering the reassembly of the fragments of the gilt-bronze crown. After conservation treatment, the gilt-bronze hat, shoes, and other relics were restored to their original forms and researchers were able to identify incised designs of a three-legged bonghwang(鳳凰), fish scales, lotus flowers, and other motifs. This study presents the major features of the fragments of gilt-bronze relics from Ipjeom-ri Tomb 1 and the methods of their production in order to provide basic material for their restoration and allow the eventual restoration of the giltbronze crown to its original condition.

  • Two new SAM-dependent methyltransferase encoding genes (fvsmt1 and fvsmt2) were identified from the genome of Flammulina velutipes. In order to make a comprehensive characterization of both genes, we performed in silico analysis of both genes and used qRT-PCR to reveal their expression patterns during the development of F. velutipes. There are 4 and 6 exons with total length of 693 and 978 bp in fvsmt2 and fvsmt1, respectively. The deduced proteins, i.e., FVSMT1 and FVSMT2 contained 325 and 230 amino acids with molecular weight 36297 and 24894 Da, respectively. Both proteins contained a SAM-dependent catalytic domain with signature motifs (I, p-I, II, and III) defining the SAM fold. SAM-dependent catalytic domain is located either in the middle or at the N-terminal of FVSMT2 and FVSMT1, respectively. Alignment and phylogenic analysis showed that FVSMT1 is a homolog to a protein-arginine omega-N-methyltransferase, while FVSMT2 is of cinnamoyl CoA O-methyltransferase type and predicted subcellular locations of these proteins are mitochondria and cytoplasm, respectively. qRT-PCR showed that fvsmt1 and fvsmt2 expression was regulated in different developmental stages. The maximum expression levels of fvsmt1 and fvsmt2 were observed in stipe elongation, while no difference was found in mycelium and pileus. These results positively demonstrate that both the methyltransferase encoding genes are involved in the stipe elongation of F. velutipes.

  • Inside Out(2015) and The Spiriting Away of Sen And Chihiro(2001) have similar narrative structures and scenes. This paper aimed to compare and analyze the intermedial relationship between the two animations. The result of the study showed intermedial relationship between Inside Out and The Spiriting Away of Sen And Chihiro, which was produced and released about 14 years before. However, it was hard to say the former referred to the system of the latter and adopted it. When seen from the narrative structure of exposition, development, crisis, climax, resolution, in Inside Out, various motifs of The Spiriting Away of Sen And Chihiro were restructured, creating a new feeling. This study considered intermediality as something that a single medium overcomes limitations and is transformed through materials, or media, and an important way to provide consumers with contents of better quality, and using Rajewsky's frame of analyzing intermediality, compared and analyzed the relationship of the two animations.

  • The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yi tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery or $appliqu{\acute{e}}$ pattern have a high artistic value in that its shapes are diverse, splendid and each one has its own peculiar elegance. As for the research method, I examined the Yi tribe's history, culture, traditional costumes and patterns through related books, research papers and inter web sites. As for the result, the Yi tribe's costumes consisted of a jacket, trousers or a skirt, an apron and a belt. Although the favorite color of the costume is black color, there are splendid embroidery or $appliqu{\acute{e}}$ decorations with the colors of red, yellow, green and purple on the chest or shoulder part of a jacket, the adjusting lines, cuffs or a part of a trousers and aprons. Patterns in their traditional clothing also show details that depict traditional cultural ideas that have long been formed in various fields, such as aesthetics, religion, philosophy, and customs. Moreover, most patterns displayed in their traditional clothing contain nature motifs and represent unique and beautiful designs; some patterns are even reminiscent of abstract paintings by modern artists. In conclusion, the traditional patterns of Chinese ethnic minorities reflect the values and notions of these races as well as decorative magnificence and a unique spiritual image. In other words, traditional patterns indicate the spiritual depth or symbolic stories beyond mere formative beauty.
