The purpose of this study is to fundamentally examine the vests of the robes “Daeraebok” and “Soraebok” of the Korean Empire from the 1876 Port Opening to the 1910 annexation of Korea to Japan. Among the collections of different robes of the Korean Empire which belong to various universities and institutions, only the vests were surveyed. The shape of the vests in the Korean Empire were single-breasted and doublebreasted. Most V-necklines and vests with a shawl collar look like a tailored collar, where the collar outline was shaped like a notched and picked collar, which is a mix of the step collar and roll collar of the 19th century. The rear center line was not flat, but inclined to a triangle. All vests of the robe Daeraebok were equipped with gold buttons, and those of the robe Soraebok had black satin buttons. The tailoring characteristic is that the front has a different material (dark black wool) from the back (black silk). This characteristic is expected to be an important basic piece of information in the restoration and reproduction of the vest, which was worn during the imperial period, especially to reveal its shape, characteristics and composition. This characteristic can also be used as data of cultural contents based on Korean modern history.

Membrane-based CO2 capture is an energy-saving way to separate CO2 from N2 in post-combustion. Chabazite (Si-CHA) zeolites with a pore size of 0.37 nm × 0.42 nm are expected to separate CO2 from larger N2 (0.364 nm) by recognizing minute size differences. The pore mouth size on the Si-CHA zeolites outer surface was reduced via the chemical vapor deposition (CVD) to increase the molecular sieving effect by disfavoring the penetration of N2. The CVD process was conducted on CHA membranes to improve their CO2/N2 separation performance. Compared to the intact CHA membranes, the CO2/N2 max separation factor for CVD-treated CHA membranes increased by ~2.5 fold under dry conditions and by ~6.4 fold under wet conditions. It is noteworthy that the membrane kept its separation performance without degradation in the presence of H2O.

This study surveys basic costumes and games from the 11 Genre paintings by Junkeun Kim in the book “Korean Games (Stewart Culin 1858-1929)”. The characters in the painting are 3 adult males, 19 boys, and 8 girls. The characters of the general dress-costumes, games and the culture of life from the late 19thCentury in genre painting of Junkeun Kimare are as follow. It is classified as a children’s game and combined game, children’s game classified one more as a boy’s game and the girl’s game from life culture. It also classified the body type and the multi complex type by game character. The boy’s games are kite-flying, spinning tops, playing shuttlecock with the feet, blind man’s bluff, yut (“Four-Stick Game”). Girl’s games are seesaw with board, blind man’s bluff, and marbles. Combined games are mount shoulder, sledge, tightrope walking for men with boy. The strengthen one’s body type were seesaw with board, tightrope walking and the multi complex type were yut (“Four-Stick Game”), kite-flying. The study results on the costumes of 19 boys, 8 girls, and 3adultsin genre paintings are as follow. Boy’s hair was knotted on the back of the head by ‘Dang-ki’ (Korean traditional hair ribbon) with the middle part in his hair which was colored red and bright brown. A ‘Go-kal’ (peaked hat), ‘Cho-lip’ (straw hat), towel hood, ‘Pung-cha’ and ‘I-um’ for winter on their heads. They wore a ‘Po’ (Korean traditional coat) which was ‘So-chang-i’, ‘Do-ru-ma-gi’ and ‘Jun-bok’ (Korean traditional vest). They were green, yellow green, violet, pink. The boys wore ‘Jeogori’(Korean traditional jacket) which were blue, red, violet, green and pink which reached down to the hip line. The variety of colors was more colorful than men’s. The ‘Jeogori’ had mostly ‘Dunggun-kit’ (a round head collar) or ‘Dangko-kit’ (a round head with nose collar), ‘Kal-kit’ (knife shaped collar) with white ‘Dong-jung’ and fit around the neck and ‘Go-rum’ was short and narrow. ‘Baji’ (slacks) were white with a colorful sash (green, blue and red) knotted at the waist, worn ‘Hang-jun’ (shank band). They wore white ‘Beoseon’ (Korean traditional socks) with Jipsin (straw shoes), ‘Mi-to-ri’, black or red, brown ‘Hea’ (leather shoes) and ‘Sulmal’ (sleigh shoes).They wore a green, indigo and red collar ‘To-si’(Korean traditional wristlets) for winter and attached a ‘Yum-lang’ (a Korean traditional pocket bag). The common man wore ‘Jeogori’ (Korean traditional jacket) which were green and white with a white lining that reached down to the hip line with white ‘Baji’ (slacks). The shape and method of wearing modern man’s Hanbok (a Korean traditional costume) remained unchanged. But it istied by another color sash for padding Jeogori in winter games. They wore white ‘Baji’ (slacks) with a colorful sash (red and white) knotted at the waist and wore a ‘Hang-jun’ (shank band).Park C.S. et al. (2009) found the same result in that the basic color was white with various intermediate colors. They wore padded Jeogori and Bajiin the winter while wearing, single a layer ‘Po’ inthe summer. They wore their hair in a topknot (sangtu) with a green color towel surrounding the forehead with ‘Bungezi’ and ‘Got’ on their head in a topknot. They wore ‘So-chang-i’, but they often did not wear ‘Po’ and put on ‘Jipsin’ (Korean traditional straw shoes) or ‘Sulmal’ (sleigh shoes). The girl’s hair was knotted to the back of the head or with partedbraidedhairso that there was a pigtail over each ear tied with a ‘Dang-ki’ (a Korean traditional hair ribbon) with a middle part in the hair. ‘Jeogoei’ was short and fitted with the narrow sleeve of a short and narrow ‘Go-rum’. It has ‘Dunggun-kit’ (a round head collar) or Dangko-kit (a round head with nose collar) with a white ‘Dong-jung’ and fit around the neck.They wore indigo, green, red ‘Jeogori’ matching the color of the ‘Kit’ (collar), ‘Go-rum’ (ribbon), ‘Kut-dong’ called ‘Ban-hoijang-jeogori’ and with a indigo/red, green/red, and red/indigocolor combination.They wore ‘Chi-ma’ (a Korean traditional skirt) colored red, green, and pink that contrasted with the ‘Jeogori’. The right side of ‘Chi-ma’ was covered to the left side and knotted by a waist band stringin the front of the chest and tucked up skirt. The width of ‘Chi-ma’ was adequate. The white inner slacks came from under the skirt. They put on ‘Jipsin’, brown ‘Hea’ (leather shoes). Through genre painting in the 19thcentury, we know a boy’s ‘Jeogori’ and ‘Ba-ji’ were similar to a modern man’s and boy’s ‘Hanbok’ with a traditional method of wearing. We believe that the originality of a traditional costume was an unchangeable characteristic. Girl’s ‘Jeogori’ and ‘Chi-ma’ changed in length and width, and method of wearing; however, the basic shape did not change. The analysis for artist’s genre painting which was ordered by a foreigner and the late of 19thcentury’s children’s costume and game of life culture is useful to match the counters and show how to wear a modern Korean costume used to understand the ‘Hanbok’ and establish a costume of life.

This research is regarding Park Ki-Jong’s Western-style court costume and emphasizes the shape and style peculiarities of Western-style court costumes in the Korean Empire from the 1876 Port Opening to the 1910 annexation of Korean to Japan. Park Ki-Jong’s frock coat was made during the period of the established law from 1900 to 1910. 1) The brand was ASADA TAILOR from Kyung-Sung. 2) The shape was long at the front and back, and it featured a picked lapel and double breast with six buttons to fasten and two buttons for decoration on the upper part. 3) The frock coat's materials were black wool fabric and black ridged silk. The lining's material was black plain silk and the sleeve's lining was white with blue striped silk. 4) The front separated the upper and bottom parts. The bottom was composed of a one-piece A-line skirt that continued from the front to back. The top of the back was separated by the princess line and the center-back seam was also separated with a vent. However, the center-back of the waistline was not separated, and it continued to one piece. The sleeve shape was a two-piece sleeve style with a phony vent and two wrapping buttons.

The invasive black soldier fly, Hermetia illucens, has been paid much attention as an excellent organic matter decomposer. We conducted the nationwide survey and the population genetic study using a mitochondrial cytochrome C oxidase 1 gene to understand its genetic diversity and distribution pattern in Korea. The results show that it has successfully settled down in South Korea and there are only 10 haplotypes and the populations of the insect are highly differentiated. The results indicate that only few maternal lineages were introduced and their dispersal was restrained due to their short distance flying tendency since their introduction.

evolution of multicellular organisms. Especially in insects, a large amount of bacterial symbionts are illustrated. Among the insect taxonomic group, sap feeding insects, mostly Heteroptera, that feeds on poor nutrient sources from plants, have developed special organs where symbiotic bacteria can reside. The bacteria mainly provide the host insects with some essential amino acids. This has built evolutionarily unbreakable tie between the symbionts and the their hosts. Here we present an obligate symbiont from Lycorma delicatula (Heteroptera: Fulgoridae) being thought to invade the Korean penninsula recently. Based on the partial 16s rRNA gene sequence, the symbiotic bacterium is identified as Cadidatus Sulcia mullleri. The Genbank data indicates that the bacterium is found in various heteropteran families. This may imply the acquisition of the bacterium precedes the hosts' divergence, though there is an alternative postulation. We discuss its distribution in the sap-feeding insects and potential role on survival of L. delicatula and paratransgenetic application of the bacterium in controlling L. delicatula.

The black soldier fly (Hermetia illucens) (Diptera: Stratiomyidae) is an invasive species that is thought to be endemic in Korea. The insect has been paid much attention thanks to its ability to decompose organic wastes. We collected the insect nation-wide in 2006 and 2010 to investigate its genetic structure based on the mitochondrial cytochrome oxidase 1 (mt CO1) haplotype. The results show that during the time period the insect seems to lose some rare haplotypes. We conclude that the insect may have experienced genetic bottleneck while its settlement in Korea. In our presentation, we show its updated haplotype network and genetic differentiation and propose potential explanations.
