  • The subfamily Ennominae is one of the most species-rich taxa of Geometridae that include more than 9,700 species worldwide and over 280 species in South Korea. Herein, we present the first report of five species of Ennominae. Abraxas flavisinuata can be characterized by the white wings, a thick black postmedial line that is medially and dorsally broken with an orange band, large rounded black discal dots on the forewing, and a black dotted postmedial line on the hindwing. Lomographa claripennis can be characterized by the whitish wings, the black undulating postmedial line as well as the minute blackish discal dot on the forewing, and the black undulating postmedial line with a minute black discal dot on the hindwing. Arichanna tetrica can be characterized by the grayish forewings, thick black transverse ante- and postmedial lines, a large blackish discal dot, whitish apical streak on the forewing, and scattered black dots on the whitish hindwing. Apocleora rimosa can be characterized by the brown ground color of the fore- and hindwings, the black slanted ante- and postmedial lines of the forewing, and two black medial lines on the hindwing. Ourapteryx japonica can be characterized by the white wings, the dark brown transverse ante- and postmedial lines with a long discal dot on the forewing, and the dark brownish transverse antemedial line as well as a termen that has a sharp white tail with one large dark reddish dot and one small black dot on the hindwing.

  • We compared effects of fruit, leaf, and stem extracts from black raspberry on improvement of cholesterol and blood pressure in HepG2 and HUVEC cells, respectively. Cholesterol secretion was inhibited by water extracts of unripe fruit and stem, but not leaf of black raspberry in HepG2 cells. Also, water extracts of unripe fruit, leaf, and stem reduced HMG-CoA reductase activity. Furthermore, nitric oxide production and expression of angiotensin-converting enzyme (ACE) protein were regulated by extracts of fruit, leaf, and stem of black raspberry in HUVEC cells. Overall, the rank order according to the improving level of cholesterol and hypertension is as follows: stem > fruit > leaf. In addition, various polyphenol compounds displayed inhibitory effects of HMG-CoA reductase activity and ACE expression. Thus, these data suggested that leaf and stem as wells as fruit of black raspberry can be used as useful food resources for reduction of cholesterol and blood pressure.

  • This study was performed to compare the physicochemical characteristics between imported dry-cured Hams from black and white pigs available in the domestic market. The black dry-cured hams contain higher moisture and ash contents than that of white hams, whereas the black dry-cured hams had lower fat contents than that of the black ones (p < 0.05). The hams from black ones had lower lightness ($L^*$) and yellowness ($b^*$) values than those from the white ones (p < 0.05). Moreover, the pH values and salt contents of the hams from the black ones were higher than those from the white ones (p < 0.05). Moreover, the black ones had a higher water holding capacity (WHC) than that of the white ones (p < 0.05). The thiobarbituric acid reactive substances (TBARS) values of the black ones were lower than those of the white ham samples (p < 0.05). For texture profile analysis, hardness, gumminess, chewiness, cohesiveness and shear force values were significantly lower in the black ones than in the white samples (p < 0.05). Saturated fatty acids in the white ones were higher than in the black ones, whereas unsaturated fatty acids in the black ones were higher (p < 0.05). Free amino acids such as aspartic acid and glutamic acid in the black ones were higher than in the white ones (p < 0.05). The shrinkage of muscle fiber was stronger in the white ones. Considering the meat quality parameters of ham, the black ones showed a superior meat quality. In general, this research can be used as fundamental information for the mass production of dry-cured hams in Korea.

  • Ladysmith Black Mambazo is a group of men influenced by South African traditional Zulu a cappella and American black music. The Jubilee Choir of the United States came to South Africa in the 1870s and influenced South African music while performing. Ladysmith Black Mambazo's music can be the result of the combination of the indigenous Zulu a cappella and the American Jubilee music style. This group participated in Paul Simon's album "Graceland" and became world famous. The album won a Grammy Award for sales of millions of copies. After that, they released their own albums and won 5 times Grammy Awards (nominated 15 times) They inherited and developed Zulu music under the philosophy of "preserving musical heritage". As a samely non-Western country, with hope their spirit, inheriting old one and innovating new one, gives positive inspiration for Korean music, I investigated how their music, 'Black Is Beautiful', 'Homeless' are influenced by the western music and inherited their own traditional music in it.

  • The purpose of this study was to investigate the effects of black foods (black rice and black garlic) and the ratio of black garlic on the quality of Sulgiddeok. Pasting properties as measured by a rapid visco analyzer (RVA) were lower for black rice flour than white rice flour. Colorimetric analysis revealed that L, a, b values were dependent on the type of rice. For texture profiles, texture was associated with RVA profiles. During storage, hardness of black rice Sulgiddeok increased to a lesser degree than that of control. After observation via scanning electron microscopy (SEM), black rice Sulgiddeok showed a honeycomb-like network structure. In sensory analysis, black rice Sulgiddeok showed a tendency to prefer the control. The addition of appropriate black garlic (BG1) helped to improve the quality. In accordance with the aforementioned results, decreased retrogradation related to black rice Sulgiddeok and black foods (black rice and black garlic) could result in quality products with high nutritional value.

  • In this letter we will investigate the possibility whether primordial black holes can grow to become galactic black holes or not. We find that even a primordial black hole with the probable maximum mass cannot grow in a short timescale. Only a hole with the initial mass of order $\sim10^4M_{\odot}$ can significantly grow to become a galactic hole.

  • The purpose of this study is to abstract the image from black dress, which has been favored by many people regardless of the times and examine it throughout the history of drss and thereby clearly define the images that black limplies in dress. Color image is a visual symbol, an image that forms through a combination of visual stimulus created by color, coupled with all the external factors related to it. Black is a one-dimensional color, of which the impact is subjective to its energy, which depends on light reflected on the object, and its texture. Therefore, black projects different images, depending on its surroundings. In general, black has had negative connotations in the Western culture. In dress, however, it has implied other various images different from the general negative ones. By combining general images of black and those exprssed in dress, major images of black were categorized into dignity, elegance, eroticism, asceticism and tragedy. Dignity is a category similar to the sublime. Dress with dignity has sharp contours and is generally made of velvet or silk which can be characterized by their splendor and voluminous-ness, exaggerating the body of a person wearing it. Such costume is mostly found in powerful countries in history such as Burgundy Court in the 15C, Spain in the 16C. Netherlands in the 17C. Elegance evokes grace and beautifulness. It includes elegance, grace, beauty and dandyism as subcategories or silk. Good examples are dandies' black costume and Ladies black and white dressees in the 19C. Eroticism is an image which expresses sexual attractiveness. Costume with eroticism is made of velvet or silk, which project sumptuousness through reflection. Such costumes expose parts of the body or are tightly tailored in order to emphasizes body contours. Asceticism means restraint from physical and mental desires. Costume with asceticism makes a person wearing it look smaller by covering the whole body. Puritan's black dresses and Bourgeoisie's black suit are good examples. Tragedy is anguish. sorrow. Black costume with grievous feelings such as mourning dresses is made of lusterless textile concealing most of the body except for the face.

  • The quality characteristics of cookies containing black rice flour, which has a greater variety of functional components than wheat flour, were studied. The results of the pasting properties shows that the inclusion of black rice flour to the wheat flour-mixture did not affect the pasting temperature but increased the enthalpy, indicating that more energy is needed for the starch gelatinization. The total dietary fiber and total polyphenol content increased and the cookies color became darker and deeper with increasing black rice flour content. According to the results from TA on texture, the hardness decreased and the crispness increased significantly (both, p<0.001) with increasing black rice flour content. From the acceptance test, the appearance, aroma and texture of the cookies with added black rice flour were significantly (p<0.001) lower than those of the wheat flour cookies. However, the taste and overall acceptance of the cookies with added black rice (lour did not differ significantly from those of the wheat flour cookies. According to the results from the sensory evaluation, the aroma, black rice flavor, crispness, graininess and color(gray-violet) of the cookies increased significantly(p<0.001) with increasing black rice flour content and those of the cookies with 30% black rice flour had the highest values among the cookies which weren't significantly different from those of the cookies with 20% black rice flour. From the above results, the optimal ratio for the addition of black rice flour to the cookies was 10% from the viewpoint of the sensory evaluation and functional components.

  • To enhance the physiological activities and reduce the off-flavor of garlic in the Kimchi, we manufactured the Kimchi seasoning replaced with 25~75% black garlic instead of raw garlic and measured the contents of antioxidants and antioxidant activities. The polyphenol compound content was $270.91{\mu}g/mL$ in the control and $278.18{\sim}305.75{\mu}g/mL$ in the Kimchi seasoning with black garlic. The polyphenol compound content increased by increasing the amount of black garlic in the Kimchi seasoning. The polyphenol compound contents gradually decreased during storage period. The flavonoid compound content was 26.18 mg% in the control and 26.80~38.72 mg% in the Kimchi seasoning replaced with 25~75% black garlic. The flavonoid compound contents increased by increasing the amount of black garlic. The flavonoid contents were different from those of polyphenol compounds during storage periods. In the case of DPPH electron donating abilities, DPPH electron donating ability of the control was 84.82%, which showed a lower antioxidative activity than the Kimchi seasoning replaced with black garlic. The electron donating abilities of the Kimchi seasoning replaced with black garlic were increased as the amount of black garlic was increased. In the lipid peroxidation test, the control showed no lipid peroxidation during the storage period. The Kimchi seasoning replaced with black garlic also inhibited lipid peroxidation during storage as in the control. However, it showed lower activity than the control. Reducing power was higher in the Kimchi seasoning replaced with black garlic than in the control. The higher the ratio of black garlic, the higher the reducing power.
