  • In this study, we investigated the effect of silkworm, and its by-products on exercise endurance, muscle mass, and fatigue recovery using ICR mice model. Powders of silkworm, pupae, dongchunghacho, and silk powder were suspended in water and feed to mice for 2 weeks. The forced swimming time was increased by 4.3, 4.1 and 2.8 seconds after silkworm, pupae, and dongchughacho administration compared to DW fed group. Increases in exercise ability were achieved by difference mechanism according to feeding materials. Pupae increased muscle mass by 129% compared with the control group which may effect on elongation of swimming time. Dongchunghacho improved the plasma concentrations of fatigue markers such as creatinine, blood urea nitrogen (BUN), and D-lactate. Silkworm administration showed dual effect, the muscle mass induction (114% vs. control) and anti-fatigue (plasma creatinine, BUN, and D-lactate were 63, 75, and 78% vs. con) effect which contributed most elongated swimming time. In conclusion, silkworm and its by-products including pupae and dongchunghacho with the predominant protein and bioactive components improved muscle mass and showed anti-fatigue effect which could promote exercise performance ability.

  • Bombyx shini Park & Sohn, 2002 (Lepidoptera: Bombycidae), which was listed as an endemic species in South Korea has recently been renamed as the East Asian silk moth Rotunda rotundapex Miyata & Kishida, 1990 (Lepidoptera: Bombycidae). In this study, we sequenced the complete mitochondrial genome (mitogenome) of the R. rotundapex to announce genomic characteristics and to clarify its validity with a new name. The 15,294-bp long complete mitogenome comprises a typical set of genes [13 protein-coding genes (PCGs), 2 rRNA genes, and 22 tRNA genes] and one major noncoding, A + T-rich region, with an arrangement identical to that observed in most lepidopteran mitogenomes. The A/T content of the whole mitogenome was 79.22%; however, it varied among the regions/genes as follows: A + T-rich region, 91.62%; srRNA, 84.67%; lrRNA, 83.01%; tRNAs, 81.43%; and PCGs, 77.46%. Phylogenetic analyses of 35 species in the Bombycoidea superfamily showed the sister relationship between the families Sphingidae and Bombycidae s. str., with the higher nodal support [bootstrap support (BS) = 78%]. The Saturniidae was placed as the sister to the two families, but the nodal support for this relationship was low (BS = 53%). Current R. rotundapex was placed together with previously reported con-species with the highest nodal support, forming a separate clade from Bombyx, validating that B. shini can have a new genus name, Rotunda. However, the Korean R. rotundapex showed a substantial sequence divergence at 5.28% to that originated from an individual of type locality Taiwan in 1,459-bp of COI sequences. Considering such a high sequence divergence an additional study, which includes morphological and DNA barcoding data from further extensive distributional range maybe is needed for further robust taxonomic conclusion.

  • 본 연구에서는 영양적으로 우수한 품질의 두부와 저장성 연장을 위한 가공두부의 다양화를 위한 시도로서, 비단두부를 된장, 고추장에 담금하면서 수분, pH, 염도, 색도, 유리아미노산, 기계적 조직특성치, 총미생 물수, 관능평가를 실시하여 다음과 같은 결론을 얻었다. 두부장의 수분함량은 담금 4주까지 급격한 감소를 보이다가 담금 6주에는 미미한 증가 경향을 보였다. 고추장 담금 두부장의 pH는 담금기간이 경과할수록 감소하는 경향을 보였으며, 된장 담금 두부장은 감소 후 약간 증가하는 경향을 나타냈다. 두부장의 염도는 담금 2주에 급격하게 증가하다가 담금 4주부터는 완만한 증가를 보였다. 두부장의 색도는 담금 기간이 경과함에 따라 L값과 b값은 감소하였으며, a값은 유의적으로 증가하였다. 고추장 담금 두부장의 총 미생물수는 담금 2주에 급격히 증가하였으나, 담금 4주에는 감소, 담금 6주에는 $3.0\~6.7\times10^3 CFU/ml$로 약간 증가하는 경향이었으며, 된장 담금 두부장의 총 미생물수는 담금 2주시에는 급격히 증가하였다가 그 이후는 계속 감소하는 경향을 나타내어 약초첨가 두부장의 총 미생물수는 무첨가두부장보다 높은 것으로 나타났다. 장담금 전, 두부 시료의 총 유리아미노산 함량은 $0.16\~0.92mg/ml$로 미량이었으나, 장담금 4주 시의 고추장 담금 두부장은 10mg/ml 전후, 된장 담금 두부장은 40mg/ml 전후로 높아졌으며, glutamic acid, tyrosine, aspartic acid 김 순으로 많았으며, histidin, methionine 등은 낮은 함량을 나타냈다. 두부장의 기계적 조직특성치인 견고성, 점착성, 씹힘성은 담금 초기에 급격히 증가하다가 담금 4주부터 감소하는 경향을 나타냈으며, 탄력성, 응집성은 담금 기간이 길어짐에 따라 유의적으로 감소하는 경향을 보였다. 두부장의 관능평가 항목에서는 일반두부장(mok-k. mok-d)이 약초첨가 비단두부장보다 높은 점수를 얻었다. 본 연구에서는 두부 제품의 다양화를 위한 시도로서 두부장의 이화학적 특성을 검토하였다. 심도 있는 각종 미생물 관련 연구와 다양한 시료에 의한 관능평가가 이루어져 영양적으로 우수한 두부가공품으로서 개발 가능성이 기대된다.

  • The wave of Avant-garde swept away all in the unique social background so called 'October Revolution' and the early 1900 Russian society which was able to absorb and accept anything. The Russian avant-garde has been affected by the Cubism and the Futurism those had peculiarly appeared in the early twentieth century, spreaded out to three spheres: the Suprematism, the Rayonism and the Constructivism. The Russian Constructivism has appeared in this background, concretely and ideally ex-pressed the ideology of the revolution into the artistic form and made an huge influence to the whole Russian society. The Constructivist like Tatlin, naum Gabo, Pevaner, Rodchenko, Stepanova, Popova and Exter gave great effect on the Soviet Constructive fashion design in 1920's after the Revolution. The Soviet costume in 1920s hold in common the characteristicss of the Constructive graphic as it is, geometrical and abstractive form, energetic and motility. In fashion design, these graphic qualities have been showed as the application of geometrical form and architectural image, physical distortion and transformation. And in textile design, the simple, dynamical presentation has been appeared. We can classify the Soviet costume at this time into three occasions. The first term is from late 1910 th mid 1920, and it is altered from folk costume design to modern one. With Lamanova as the first on the list, using the folk mitif, the Constructive expression of simple form has been gradually revealed in design. Designers like Makarova, Pribylskaia and Mukhina produced the plane, simple chemise style with the decoration of the Russian traditional motif. From early to late 1920 is the second term, and it is at the pick of the most active processing of the Constructive design. Not only at the costume in daily life but also at the theatrical costume and textile, the con-structive design has been represented all avail-able fields. Many Constructivists including Stepanova, Popova, Exter and Rodchenko took part in the textile design and costume design so as to evlvo their aesthetic concept. The third term is from late 1920 to early 1930. The socialistic realism has dominated over the whole culture and art, the revolutionary dynamic motif has been presented also in textile design. The formative features of Soviet Constructive fashion design are; silhouette, from, motif, color and fabric. The first, the silhouette : a straight rectangular silhouetted has been expressed through the whole period and a volumed one with distorted human body shape has introduced in the theatrical costume design. The second, the form: many lengthened rectangular forms have been made at beginnings, but to the middle period, geometrical, architectural forms have been more showed and there are energy and movement in design. At the last period, only a partial feature-division has been seen. The third, the motif; no pattern or ethnic motif has been partly used at beginnings, a figure like circle, tri-angle has gradually appeared in textile design. At latter period, a real-existent motif like an airplane has been represented with graphing and simplicity. The fourth, the color ; because of insufficient dyeing, neutral color like black or grey color has been mainly covered, but after middle term, a primary color or pastel tone has been seen, contrast of the fabric; without much development of textile industry after the Revolution, thick and durable fabrics have been the main stream, but as time had going to the last period, fabrics such as linen, cotton, velvet and silk have been varously choesn. At the theatrical costume, new materials like plastics and metals that were able to accentuate the form. The pursuit of popularity, simplicity and functionalism that the basic concept of Constructive fashion is one of the "beauty" which has been searching in modern fashion. And now we can appreciate how innovative and epochal this Soviet Constructive fashion movement was.ement was.
