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.

In the previous work we made a long term evolution code for the central black hole in an active galactic nucleus under the assumption that the Blandford-Znajek process is the source of the emission. Using our code we get the evolution of the angular velocity of the precession for a supermassive black hole. We consider a hole at the center of an axisymmetric, ellipsoidal galactic nucleus. Our numerical results show that, only for the cases such that the stellar density or the mass of the black hole is large enough, the precession of the black hole - presumably the precession of the galactic jet - is interestingly large.

The pottery and porcelain of Myanmar is very various such as Celadon, Black glazed large Jar and White galzed Jar painted Green Colour. In these Myanmarese Ceramics, Black glazed large Jar is very important to understand the Character and Role of Myanmar Ceramics. The description on the Black glazed large Jar of Myanmar is seen in several Books such as a travel essay of Ibun Battuta, Duarte Barbosa, The book of Duarte Barbosa: A Account of the Contries Bordering on the Indian Ocean and their Inhabitants, Jan Huygen van Linschoten, Volker, T., Porcelain and the Dutch East India Company These descriptions on the Black glazed Jar in these Books are important evidence to discovery the existence of it and its Types and Price and Use. The appearance of Black glazed Jar of Myanmar is considered in the Middle of 14C with the description of the Book of Ibn Battuta. Furthermore, Excavated from the Shipwreck of China in the Sinan, Chellanamdo, it is certain that the Black glazed large Jar was already existed in the early of 14C. And it was considered that the Shipwreck of China in the Sinan, Chellanamdo was started from Ninbo(寧波) of China to the destination of Japan with the Inscrition made Bamboo. So we know that The route of $Ninbo{\rightarrow}Korea{\rightarrow}Japan$ is very important in the Trade Ceramics of East Asia in 14C. And The size of Black glazed Jar has 3 types, Large, Middle and Small. The large type is used as a Tools for Water and Oil. The small type is the personal bottle for drinking. The Price of Black glazed Jar of Myanmar was changed as times go by. The price of the late of 16C and the early of 17C is 30 prolin and the late of 17C is 8 Prolin. The price of the Black glazed Jar of Myanmar in the late of 16C and the early of 17C is estimated 3 times for the price of the late of 17C. and This change of the price of Myanmarese Black Glazed Jar is decided on the Demand and Supply. and the Black glazed Jar of Myanmar was mainly used for the tools for Morpin in the year of 1620 and for Salt and Sugar in the year of 1640 and for Water and Oil in the late of 17C.

Bacillus 균주를 이용하여 42$^{\circ}C$에서 72시간동안 발효된 검정콩 청국장의 몇 가지 생리활성 및 sioflavone(daidzein, genistein) 함량을 조사하였다. B. subtilis 보다는 분리균주 Bacillus megaterium SMY-212 균주를 첨가한 청국장이 항균활성이 매우 높았고, 대립 검정콩의 메탄올 추출물이 소립 검정콩의 것보다 항균 효과가 우수하였다. 청국장의 수소공여능은 대립 및 소립 검정콩 청국장에서 각각 76.4 및 75.5%를 나타내었으며, B. subtilis 및 SMY-212 를 첨가한 것은 무첨가보다 약간 높게 나타났다. 아질산염 소거능은 대립 검정콩이 소립 검정콩보다 그 효과가 크게 나타났으나, 균종간에는 차이가 나타나지 않았다. Linoleic acid 에 대한 과산화물가 및 흰쥐의 liver homogenate에 의한 TBARS 함량으로부터 볼 때 검정콩 청국장의 메탄올 추출물은 상당한 항산화효과가 있었다. 그 효과는 소립 검정콩의 청국장 추출물이 대립 검정콩의 청국장 추출물보다, 균주 첨가 청국장 추출물이 균주 무첨가 청국장 추출물보다 크게 나타났다. 청국장의 daidzein 및 genisteing함량은 발효 중 증가하였으며, 대립 검정콩 청국장이 소립 검정콩 청국장에 비하여 약간 높았다.

Black carbon, which is a by-product of combustion of fossil fuel and biomass burning, is the component that imposes the largest uncertainty on quantifying aerosol climate effect. The direct, indirect and semi-direct climate effects of black carbon depend on its state of the mixing with other water-soluble aerosol components. The process that transforms hydrophobic externally mixed black carbon particles into hygroscopic internally mixed ones is called "aging". In most climate models, simple parameterizations for the aging time scale are used instead of solving detailed dynamics equations on the aging process due to the computation cost. In this study, a new parameterization for the black carbon aging time scale due to condensation and coagulation is presented as a function of the concentration of hygroscopic atmospheric components and the black carbon particle size. It is shown that the black carbon aging time scale due to condensation of sulfuric acid vapors varies to a large extent depending on the sulfuric acid concentration and the black carbon particle size. This result indicates that the constant aging time scale values suggested in the literature cannot be directly applied to a global scale modeling. The aging time scale due to coagulation with internally mixed aerosol particles shows an even stronger dependency on particle size, which implies that the use of a particle-size-independent aging time scale may lead to a large error when the aging is dominated by coagulation.

Grapes (large seed strains)were treated with fumigation using SO\ulcorner and seal-packaged by PE film, then storage at 0$^{\circ}C$ at 90$^{\circ}C$ RH for the test of storage life. The fruits weight loss and abnormal fruits increased with storage. The abnormal fruits were rapidly produced after 80 days, however, these rates of Rubel muscat and Shingyoku were only 8.0 and 8.3%, respectively. After 90 days, the rate of Rubel muscat was 19.1%, resulting in the least rate. Moisture content of Kaiji and Honey black slightly increased and that of other grapes decreased. Soluble solids content and acidity decreased except Shingyoku and Honey black, however, sugar/acid ratio increased with these strains. The external appearances were depressed with storage but sensory test value of Shingyoku, Honey black, Rubel muscat were ranged from 7 to 9, showing good evaluation. The hardness of Honey black after 90 days resulted in the highest value 0.51 and that of Izunishiki and Kaiji were 0.23-0.25, showing the least value.

After imposing a large pre-strain, anisotropy increases with increasing residual extension ratio. Gums have very low residual extension ratio and exhibit little anisotropy, while black filled SBR and especially sulfur-cured carbon black filled NR have large set and anisotropy. For carbon black filled rubber, samples subjected to tensile loading in perpendicular to the pre-strain direction have the same stress-strain curves shape as the sample without pre-strain (=isotropic samples), but slightly lower modulus. However, compared to isotropic or perpendicular directional samples to pre-strain direction, samples subjected to tensile loading in parallel to the pre-strain direction show low stress at low deformation, but have high stiffness at high deformation. Normalized anisotropy changes with strain. The normalized anisotropy for various deformations is a linear function of residual extension ratio.

검정콩을 이용하여 제조된 청국장의 기능적 특성을 평가하기 위하여 검정콩 청국장의 메탄올 추출물에 대한 몇가지 기초적인 생리활성과 발효중 phytoestrogen화합물(daidzein, genistein)의 함량변화를 조사하였다. 대두 청국장의 추출물은 대부분의 시험균주에 대하여 거의 항균활성이 없거나 약하게 나타났으나, 검정콩 청국장의 추출물은 시험균주 모두에서 항균활성을 나타내었다. 특히, 소립 검정콩의 청국장 추출물의 항균활성이 대립 검정콩보다 강하였다. 대립 및 소립 검정콩 청국장의 수소공여능은 각각 76.4및 75.5%로서 대두 청국장의 67.3%에 비하여 더 높게 나타났다. 또한 아질산염 소거능은 각 청국장 추출물에서 대조구에 비하여 모두 90%이상을 나타내었다. Linoleic acid에 대한 과산화물 및 흰쥐의 간 지질에 대한 TBA의 수치는 청국장의 추출물을 첨가한 시험구가 첨가하지 않은 대조구에 비하여 낮았으며, 그 항산화 효과는 소립 검정콩, 대립 검정콩 및 대두 청국장의 추출물 순이었다. Daidzein 및 genistein의 함량은 청국장 발효중 점진적으로 증가하였으며, 대두 청국장에 비하여 검정콩 청국장의 함량이 훨씬 높았고, 대립 검정콩이 소립 검정콩으로 제조한 청국장의 함량보다 높게 나타났다. 또한 genistein 함량은 대체로 daidzein 함량의 2배정도였다.

We suggest a possible scenario of an astrophysical black hole with non-vanishing electric charge and magnetic flux. The equilibrium charge on a rotating black hole in a force-free magnetosphere is calculated to be Q $\~$ BJ with a horizon flux of ${\~}BM^2$, which is not large enough to disturb the background Kerr geometry. Being similar to the electric charge of a magnetar, in sign and order of magnitude, both electric charge and magnetic flux are supposed to be continuous onto a black hole.

In discrete red and black, you can stake any amount s in your possession, but the value of s takes positive integer value. Suppose your goal is N and your current fortune is ${\Large\;f},\;with\;O<{\Large\;f}. You win back your stake and as much more with probability p and lose your stake with probability, q=1-p. In this study, we consider optimum strategies for this game with the value of p less than ${\frac{1}{2}}$ where the house has the advantage over the player. It is shown that the optimum strategy at any ${\Large\;f}$ is the DBold strategy which is to play boldly in discrete red and black when $p<{\frac{1}{2}}$. And then, we perform the simulation study to show that this strategy, which is to bet as much as you can, is optimal in discrete case.
