A natural intergeneric hybrid between Rhodeus pseudosericeus and Acheilognathus signifer was collected in their sympatric area, the Jucheongang (stream), the Namhangang (river), Korea. Morphological characters as well as mitochondrial cytochrome b (mt-cyb) gene were investigated to confirm the natural hybrid origin. In the comparison of morphological characters, the natural hybrid appeared to have intermediate characters between two parental species in several key characters such as the band of dorsal fins, the color pattern of body, and the body spot and stripe. Also, the collected specimen had an incomplete lateral line with a large number of pored scales. In analysis of mt-cyb gene, it revealed that the maternal species of the natural hybrid appeared to be R. pseudosericeus due to their 100% sequence identity. Thus, such results gave convincing evidence for the occurrence of a natural intergeneric hybrid between Rhodeus pseudosericeus and Acheilognathus signifer.

This study was carried out to find out what is the optimum conditions for RAPD of Zelkova serata. We changes the factors what affect to PCR band patterns, as a result, we established the optimum conditions as follows; template DNA 100mg, Primer 0.25uM, dNTP 100mM, Taq polymerase 1.0u, and total reaction volume was filled up to 10uL with distilled water. As the amount of primers went higher, PCR reaction rates were lowered. This reason was cause by exhaustion of primers during initial reaction. The amount of dNTP didn't showed noticable differtations between the range, but the optimum amount was 100mM for efficiency. Taq polymerase 1.0 unit was the best in the range. As the concentration of polymerase were increased, many non-specific bands were appeared, In primer selection, most Openron Random Primers are amplified in this experiment. The primers GC contents were 60, and set A, B, C, D, E, X were tested. Thermal cycler(ASTEC PC808, Japan) condition was, $95^{\circ}C$, 5min, initial denaturation, $94^{\circ}C$, 20sec, denaturation, $37^{\circ}C$, 40sec, annealing, $72^{\circ}C$, 1min, extention, 45cycle repeated and final extention $72^{\circ}C$10min.

Hanboks have evolved throughout time; for example, the curved Barae has changed into a more modern and sophisticated straight one. The development of staining techniques has increased color selections with more luxurious designs. I suggested a design of Dolbok that considers functionality, practicality and economic feasibility through a comparison of past and present designs. I suggested a fusion Hanbok based on a traditional Dolbok for baby boys and girls. An abundance of cheap resources has decreased the tradition of hand down clothes; therefore, I created functional and economic methods to adjust a Hanbok for kids to wear a long time. First, I made it possible to adjust the length of a skirt by a slip stitch (or catch) stitch with a Seurandan (ornate lower band) and placed the button on shoulder part of the skirt for baby girls. The width of skirt is designed for a 4 year old instead of 1 year old to adjust the size and compensate for growing kids; however, the clothes still look stylish despite the overlapped area. Second, I made a baby boy's vest with a belt that follows traditional methods that were comfortable for width variation. Third, I made Geodeulji (sleeve-ends trimmed with wide bias) that enabled long or short sleeves. Geodeulji made with a variety of fabric colors will enhance the decorative effect. Fourth, I made the width of clothes adjustable by putting Korum (tie) ON Jeogori for baby boys and girls. There are many studies on Hanboks but few reports on modern Dolbok. I believe that designers should further study fusion Hanboks within framework of traditional Hanbok designs to increase comfort and appeal.

In a ${\Lambda}CDM$ universe, galaxies are believed to evolve by mergers and accretions. The debris resulting from such processes remains as diffuse, low-surface brightness structures, such as outer disks, stellar halos, and faint companions. These structures will give us fruitful insight into the recent mass assembly history of galaxies, but it is challenging to observe them due to their low surface brightness. In order to explore the structural properties of outskirts of nearby galaxies, we conduct deep wide-field imaging survey with KMTNet. Here we present a progress report of data reduction for the images of NGC 1291, a lenticular barred galaxy with outer rings. To achieve accurate flat fielding, we use dark sky flat and remove the sky gradient of each exposure with a polynomial fit. As a result, we are able to reach 1 sigma depth of ${\mu}_R{\sim}29.6\;mag\;arcsec^{-2}$. We expect to investigate the surface brightness profile of NGC 1291 in 1-D profile, and color-gradient in the outer part of the galaxy using the B- and R-band images.

It is often crucial to obtain a map of flood inundated area with more accurate and rapid manner. This study attempts to evaluate the potential of satellite synthetic aperture radar (SAR) data for mapping of flood inundated area in Imjin river basin. Multitemporal RADARSAT SAR data of three different dates were obtained at the time of flooding on August 4 and before and after the flooding. Once the data sets were geometrically corrected and preprocessed, the temporal characteristics of relative radar backscattering were analyzed. By comparing the radar backscattering of several surface features, it was clear that the flooded rice paddy showed the distinctive temporal pattern of radar response. Flooded rice paddy showed significantly lower radar signal while the normally growing rice paddy show high radar returns, which also could be easily interpreted from the color composite imagery. In addition to delineating the flooded rice fields, the multitemporal radar imagery also allow us to distinguish the afterward condition of once-flooded rice field.

The aims of this study are primary data offer to silver fashion enterprise. In order to deduce design from diverse needs of silver generation, this study is required expert knowledge. For this purpose, this study applied two rounded Delphi method in which 31 experts. As a result, the following findings were obtained; From the previous studies, we found the physical changes of women in silver generation; i.e. the size of their waist and abdomen gets larger, their breasts are sagging, their limbs are thinner, upper body is bending, their height and weight get shorter and lighter. Their choice criterion of design of clothing is hide their weak points in body, youthfulness, moderate, and fashion style. Youthful design but patterns should agree with their body line so that they should be easily fit and look young. They like a jacket and pants set best regardless of spring or summer and as upper garment, they like semi fit, as pants, they prefer straight line of ankle length, and as skirts, partial elastic band and pleats, and the length of the skirts just cover their knees. This pattern in choosing their clothes represents they consider functionality as well as the aesthetics. Their preferred color for spring is lt/pink, lt/violet lt/green for summer, white and blue. Their preferred materials are wool/poly/spandex and cotton/spandex for functionality for spring, and for summer, linen poly and cotton poly seersucker for cool feeling and stability. In both top and bottom item, solid pattern follows small one in their preference on patterns, which shows that they are in pursuit of an elegant style. Our research based on this survey tries to establish what the fashion design for the silver generation should take into consideration.

This study aimed to examine emo fashion, a very recent music-related fashion trend spreading fast amongst youths, and understand emo ideas and methods of expression for a greater understanding of contemporary youth sub-cultures and fashion trends. Documentary research, positive research and in-depth interviews were used throughout the study. 4 Korean emo bands and 4 U.S. emo bands were selected based on music chart rankings, and a total of 37 photographs from the bands' Internet websites were selected, and their clothes shown in the photographs were examined. 5 Korean emo band musicians were subjects of in-depth interviews, and they were asked about their emo culture, music, fashion, ideas and styles, and photographs were taken of the subjects and evaluated, too. Lastly, Korean and U.S. emo kids were studied through photographs, and comparatively analyzed. Both Korean and U.S. emo musicians wore slim silhouettes, skinny jeans, t-shirts, sneakers, black, studded belts and plastic-framed glasses. Korean fashion expressed a less depressive atmosphere with color and other details compared to the United States, and did not prefer dark black eye make-up, which United States emo style appeared to express frequently. Korean musicians' emo fashion was closer to other youth fashions, whereas U.S. emo fashion included more formal styles such as ruffled shirts and pin-striped vests. Korean emo kids wore clothes not much different from most Korean youths, but U.S. emo kids wore a lot of eye make-up and black t-shirts with graphic or skull prints, and had more geometrical hair styles, as if cut at home. The reasons for such differences were found to be a longer emo music and culture history in the United States leading to more elaborate fashion expressions and a difference in the states of mind, such as Korea pursuing to express love, and the United States pursuing loneliness.

The genetic relationship of Bletilla striata native to Korea and Japan was investigated using random amplified polymorphic DNA (RAPD). The 156 reproducible DNA bands, consisted of 58 polymorphic and 98 monomorphic bands, were obtained by polymerase chain reaction (PCR) with selected 10 random primers. The 8 Bletilla lines have been classified into three groups according to the similarity coefficient obtained by RAPD analysis. The dendrogram showed overall correlationship between similarity coefficient of 0.48 and 0.84. The first group included A (Bletilla striata native to Korea), B (Bletilla striata variegated and native to Korea in Mokpo), C (Bletilla striata variegated and native to Korea), D and E (Bletilla striata native to Japan). In this group, it was showed that B and C had the most similar genetic relationship. The similarity coefficient between D and E was 0.77. D and E had a very close resemblance in plant height and flower color with A native to Korea, respectively. The second group included only G (dwarf Bletilla native to Japan) and had a different morphological character compared to other cultivars. The last group included F and H (dwarf and variegated Bletilla native to Japan) and they had a similarity of variegation.

In this study we investigate physical and chemical characteristics of immature and mature skipjack tuna (Katsuwonus pelamis) roes in fresh and dried forms. Fresh roes were studied for histological structure and also dried by three methods: hot air drying (HD), vacuum drying (VD) and freeze drying (FD). The obtained roe powders were analysed for proximate composition, color value, fatty acid composition, amino acid profile, equivalent umami concentration (EUC) and protein pattern. Unyolked oocytes were more common in immature roes, while fully yolked oocytes were more common in mature roes. All dried tuna roes contained high content of protein and lipid (69.31%-70.55% and 11.14%-16.02%, respectively). The powders obtained by FD provided the highest lightness value (L^*). The main fatty acid found in all roe powders was docosahexaenoic acid (DHA) (23.49%-27.02%). Glutamic acid, leucine, and aspartic acid were the three most abundant amino acids found in the powders (13.58-14.61, 8.06-8.42, and 7.81-8.39 g/100 g of protein, respectively). The mature roe powder obtained from HD provided the highest EUC value (73.09 g monosodium glutamate/100 g of samples). The protein band at molecular weight of 97 kDa (vitelline) represented the major protein. Therefore, dried tuna roe could be a functional ingredient source of protein and lipid rich in DHA and it also has potential to be used as taste enhancer with umami compound.
