Recent herbarium reexamination and field studies yielded two monocotyledonous plant taxa of the family Poaceae that could be documented in the national inventory list of species of Korea. These species, collected from Jeollabuk-do and Gyeongsangnam-do, were introduced and naturalized in Korea. Two species were identified as Holcus mollis L. and Aira elegantissima Schur. We provided the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa were also provided.

Seven new species in two genera, Sarcotragus and Bergquistia (Demospongiae: Dictyoceratida: Irciniidae), are described from Jeju Island, Korea. The separation of the two genera was made on basis of morphological evidence in skeletal structure, especially fasciculation of primary fibres and filament thickness. Two new species in the genus Sarcotragus and five new species in the genus Bergquistia are compared with other reported species.

Eleven new species of two genera, Psammocinia and Ircinia (Demospongiae: Dictyoceratida: Irciniidae) are described from Gageo Island, Ulleung Island and Jeju Island, South Korea. The separation of these two genera was made on basis of morphological evidence, especially skeletal structure with foreign debris. Six new species of Psammocinia and five new species of Ircinia were added to known fauna. All skeletal fibres are very irregular.

Twelve ciliates were collected from freshwater, marine, and brackish water habitats in Korea and taxonomic descriptions are provided based on observations of living cells and protargol-impregnated specimens. These ciliates, recorded for the first time in Korea, were classified into 12 genera, 11 families, 10 orders, and five classes. We provide brief descriptions and remarks, including microphotographs, for the 12 ciliates: Allotricha mollis, Amphileptus eigneri, Didinium gargantua, Holophrya teres, Lacrymaria marina, Novistrombidium apsheronicum, Pelagostrobilidium conicum, Pseudochilodonopsis fluviatilis, Pseudourostyla subtropica, Strombidium conicum, Urocentrum turbo, and Uronema marinum.

Three marine and one brackish-water ciliates (Dysteria crassipes $Clapar\grave{e}de$ and Lachmann, 1859; Gruberia calkinsi $Beltr\acute{a}n$, 1933; Pleuronema salmastra Dragesco, 1986; Zosterodasys agamaliev Deroux, 1978) were isolated from Incheon in Korea and their morphologies were investigated using live observation and protargol impregnation.

Two pleurostomatid ciliates, Amphileptus litonotiformis Song, 1991 and Kentrophyllum setigerum (Quennerstedt, 1867), were collected from the coastal waters of Korea. Their morphologies are described based on live observation and protargol impregnation, and their diagnoses and morphometrics are provided. Additionally, sequence information of small subunit ribosomal RNA obtained from two species were reported.

In this paper, the performance of OFDM(Orthogonal Frequency Division Multiplexing) and FMT(Filtered Multi-tone) Systems is compared under jamming environment. Two systems are multi-carrier systems to improve data rates. Through the comparison of two systems under jamming environment, the characteristics and strong/weak points of each system are analyzed.

Four species of opisthobranch molluscs collected from Jeju Island were identified as Pleurobranchus peronii Cuvier, 1804, Pleurobranchus weberi (Bergh, 1905), Aplysiopsis nigra (Baba, 1949) and Stiliger aureomarginatus Jensen, 1993. All of the species and genera examined here are new to Korea. Pleurobranchus peronii and P. weberi were easily distinguished to each species by dorsal tubercles and markings. In this report, we provided descriptions and photographs of these species for identification.

Two feather mites, Bychovskiata hypoleuci Mironov and Ddabert, 1997 and Phyllochaeta interifolia (Mégnin and Trouessart, 1884) are reported for the first time in South Korea. Specimens of these two species were collected from the common sandpiper Actitis hypoleucos. The genera Bychovskiata Dubinin, 1951 and Phyllochaeta Dubinin, 1951 are also new reports for South Korea. Here, we provide morphological descriptions and illustrations of these two species. Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) as DNA barcodes.
