Doryctinae is a large and heterogeneous group with more than 1,000 described. It is idiobiont ectoparasitoids on the larvae of wood-boring and xylophagous beetles. Some species attack larvae of wood boring lepidoptera. In the present study, fifteen species belonging to eight genera of the subfamily Doryctinae are recorded for the first time from Korea: Doryctes Haliday (2 species), Eodendrus Belokobylskij (1 species), Heterospilus Haliday (4 species), Monolexis Förster (1 species), Neurocrassus Snoflak (2 species), Rhoptrocentrus Marshall (1 species), Sonanus Belokobylskij et Konishi (1 species), Spathius Nees (3 speices). The genera Eodendrus Belokobylskij, Monolexis Förster, Rhoptrocentrus Marshall, Sonanus Belokobylskij et Konishi and fifteen species are reported for the first times from Korea. Diagnosis and host information are provided.

The genus Acteniceromorphus is taxonomically reviewed for the first time in Korea. From the previously recorded three species, two species, A. selectus (Candèze, 1894) and A. fulvipennis (Lewis, 1894) are confirmed as misidientification of species which are endemic to Japan. Another species, A. chlamydatus (Lewis, 1894) is unavailable any Korean specimens. Additionally, we found A. ferrugineipennis (Candèze, 1879) as new to Korea. We also provide a comparison of DNA barcoding for two species previously misidentified and the newly recorded species, except A. chlamydatus. DNA barcoding result shows that each species is clearly delimited at species-level from each other by large interspecific genetic distance over 7.2%.

1994년 7월 22일부터 26일까지 한국동물분류학회 창립 10주년 기념 햅동채집이 진도에서 실시되었다. 이 기간 중 채집된 히드라충류는 8과 31종으로 $동정\cdot분류$되었는데, 이 중 8종은 진도기록종이고 나머지는 진도미기록종으로 판명되었다. 진도 미기록종 중 Halecium magellanicum과 Obelia flexuosa는 한국미기록종으로 밝혀졌다. 본 연구에서 관찰되지 않은 3종의 진도기록종을 포함하여 현재까지 동정된 진도産 하드라충류는 8과 34종이 된다.

The Dryopidae (Coleoptera) is composed of approximately 300 species worldwide belonging to 33 genera; however, members of the family have not been recorded in Korea. We collected and recorded adult specimens of Elmomorphus brevicornis Sharp (=E. brevicornis brevicornis Sharp) on piles of submerged twigs and branches of a decayed tree (Prunus sp.) from a mountain stream in southwestern Korea with a comparison of the type specimens of E. brevicornis amamiensis Nomura from Japan. Both of the subspecies are raised to the species level herein. Redescription, photographs, line drawings of diagnostic characteristics, distribution map, habitat, and taxonomic notes for Elmomorphus brevicornis are provided.

A simple new technique of particle depth position measurement, which can be applied for three-dimensional velocity measurement of fluid flows, is proposed. Two color illumination system that intensity is encoded as a function of z-coordinate is introduced. A calibration procedure is described and a profile of small sphere is detected by using the present method as preliminary test. Then, this method is applied to three-dimensional velocity field measurement of simple flow fields seeded with tracer particles. The motion of the particles is recorded by color 3CCD camera. The particle position in the image plane is read directly from the recorded image and the depth of each particle is measured by calculation of the intensity ratio of encoded two color illumination. Therefore three-dimensional velocity components are reconstructed. Although the result includes to some extent error, the feasibility of the present technique for three-dimensional velocity measurement was confirmed.

The impact of antibiotic (Norfloxacin) administration ,at different concentration (50 ppm and 100 ppm) on commercial characters of bivoltine $({CSR_2}{\times}{CR_4})$ and the cross breed race $({BL_67}{\times}{CSR_101})$ was studied. The result indicated that antibiotic administration with different concentrations significantly improved the rearing and cocoon parameters like larval duration, larval weight, growth index, single cocoon weight, single shell weight and shell ratio. The post cocoon parameters like average filament length, non-breakable filament length, raw silk percentage, raw silk recovery percentage, denier, reelability and neatness were recorded significantly higher in antibiotic treated batches. The better performances of these parameters were recorded with the increase of antibiotic concentration.

방송 환경이 디지털화되면서 기존 방송 단말에서 지원하던 방송 프로그램 녹화 기능이 새로운 저작권 문제를 불러일으키고 있다. 그러나 방송 단말에 저장되는 방송 콘텐츠를 위한 적절한 보호방안이 마련된다면, 이러한 콘텐츠를 이용한 새로운 비즈니스 모델을 창출해 낼 수 있다. 본 논문에서는 방송 단말에 저장된 콘텐츠를 효과적으로 보호하고 이를 이용한 콘텐츠 유통을 지원할 수 있으며 기존의 방송 서비스 환경에 쉽게 적용될 수 있는 디지털 콘텐츠 보호 방법에 대하여 논한다.

Based on samplings during 2006-2007 on the intertidal zone of Playa Tampico, Eréndira and Punta Baja, Baja California, Ulva pertusa Kjellman (Ulvales, Chlorophyta) was recorded for the first time for the Pacific coast of Mexico. An alga native to Asia, U. pertusa has just recently been recorded in the southern coast of California (USA). The identification of U. pertusa was based on the observation of the morphology and reproductive characters of the collected specimens. Furthermore, the species identity was confirmed by molecular comparison between nuclearencoded ITS2 sequences of the Mexican samples and those of other Ulva species in GenBnak data. Habitat and distribution of U. pertusa along the Pacific coast of North America are also described. Considering our new report of its occurrence in Mexico, we conclude that U. pertusa is expanding its geographical distribution by trans-ocean introductions.
