  • Schizopora paradoxa is a white rot fungus showing great variation in hymenophoral configuration. It has been often treated as close to Irpex or Hyphodontia and frequently confused with S. flavipora which was identified as an unrecorded species in Korea. Distinct features including sizes of basidia and basidiospores as well as hymenophoral shape make S. paradoxa differ from S. flavipora. Remarkable characters of hymenophores and microscopic structures are described and their significance is discussed for the taxonomy of Korean Schizopora.

  • Sperm morphology of ho species (hpodemus agrarius coreae and Apodemus peninsulae peninsulae) of the genus Apodrmus in Korea was investigated. Two species were similar in six qualitative characters, i. e., head shape, presence of apical ridge, process, cone-like process, and mitochondrial sheath, and the degree of development in outer dense Hber, Lengths of head and midpiece were not different with each other, but length of principal plus end piece was significantly larger (P ≪ 0.001) in hpodemus agrarius coreae than that in hpodemus peninsular peninsulae.

  • Influence of characters of fly ash on the fluidity of cement paste with polycarboxylic acid type superplasticizer has been investigated in connection with the particle size of distribution, unburned carbon content, specific surface area and shape of fly ash. The fluidity of paste is increased with increasing roundness of fly ash and it is decreased with increasing n-value of Rosin-Rammler distribution function. There is a linear correlation between roundness/n-value and fluidity of fly ash cement paste.

  • Two new species of Arcuphantes Chamberlin and Ivie, 1943 (Linyphiidae), Arcuphantes juwangensis n. sp. and Arcuphantes namhaensis n. sp., are described with illustrations. All Korean Arcuphantes have a convoluted epigynal scape, and show close similarities in their morphological characters, but easily discriminated in the structures of proximal protuberances and the distal wing-shape of their epigynum.

  • The larval stage of Ceraclea labulata (Martynov) is described for the first time. The larva can be distinguished from other known larvae of Korean Ceraclea by the absence of head marking and by the shape of frontoclypeus, which is equal in anterior and posterior width. The larval case is also described. Line-drawings of key characters and discussion on Korean Ceraclea are provided.

  • 얼굴 표정은 영화나 애니메이션에서 캐릭터의 특징을 나타내기 위한 중요한 수단이며, 페이셜 캡쳐 기술은 3D 캐릭터의 페이셜 애니메이션 제작을 보다 빠르고 효과적으로 지원할 수 있다. 블렌드쉐입(blendshape) 기법은 고품질의 3D 얼굴 애니메이션을 생성하기 위해 가장 널리 사용되는 방법이지만, 전통적인 블렌드쉐입은 제작에 시간이 오래 걸리는 경우가 많다. 따라서 블렌드쉐입의 제작 기간을 줄이기 위해 전통적인 제작의 효과에 크게 뒤지지 않는 결과를 얻으려는 것이 이번 연구의 목적이다. 본문은 블렌드쉐입의 제작을 위해 크로스 모델(Cross-Model)로 블렌드쉐입을 전달 방법을 사용하고, 전통적인 블렌드쉐입의 제작 방법과 비교하여 새로운 방식의 타당성을 검증하였다. 이번 연구는 언리얼 엔진이 개발한 키트 보이(kite boy)를 실험 대상으로 삼고, 각각 두 가지 블렌드쉐입 제작 기법을 사용하여 페이셜 캡처 테스트를 실시하고, 블렌드쉐입과 연동된 얼굴 표정 제작 방법의 효과를 비교 분석하였다.

  • Aim of the present study was to provide presence of opisthorchiid metacercariae in cyprinid fish Leuciscus idus in Nura-Sarysu river, Kazakhstan. Infection rate of the ides by the metacercariae was 42%. The metacercariae, similar morphologically to those of the liver flukes, were found: elliptical in shape, $0.19-0.25{\times}0.15-0.22mm$, oral and ventral suckers nearly equal size, and excretory bladder O-shape with black content, occupying posterior part of the body. The metacercariae were divided into 2 groups with differences in size and thickness of cyst wall. Adult flukes were recovered from the Syrian hamsters infected with the opisthorch metacercariae and identified with morphological characters to Opisthorchis felineus and Metorchis bilis. DNA sequences of ITS1, ITS2, and cox1 supported the taxonomic assignment.

  • A lot of individual ginseng plants were selected in the farmer's fields to develop new ginseng varieties with desirable traits. Among them, a promising line has been developed through comparative cultivation of several lines selected with pure line separation of local raced. It was then designated as "KC (denotes Korean Ginseng)" and tested in the regional yield and adaptation trials for 10 years. KG lines grew vigorously after 4 years of age. Especially, KG 102 line arson운 them showed traits of multiple and short stems. As for the root characters, the length of taproot of KG 101 line was longer than that of local race, Jakyung-jong, or other lines ailed the root weight of KG 102 line waIn 15 % higher than that of local race. In general, KG 101, KG 103, KG 104, and Hwangsauk-jong had good root shape. Total amount of ginsenosides of ginseng taproot was the highest in KG 103 line than in local race and other lines. In these studies, we, elected three superior lines, KG 101, KG 102, and KG 103, having characteristic of good root shape, high yield, and large amount of ginsenoside, respectively.

  • Both sexes of a new species of Miraciidae belonging to the genus Amonardia Lang, 1948 are described. All materials collected from the cultivated brown alga, Undaria pinnatifida of Gijang, Korea. So far only one species, A. normani (Brady, 1872) from the algal bed at Jindo Island was recorded in Korea. The new species can easily be distinguished from its congeners by the combination of characters as follows: (1) shape of first antennular segment in female, (2) setal formular of mandible and maxillule, (3) setae of female sixth leg in female, and (4) shape of P2 endopod and exopod of fifth leg in male.
