Three species of Ellobiid molluscs collected from Korea were identified as Auriculastra duplicata (Pfeffer, 1854), Laemodonta siamensis (Morelete, 1875) and Melampus (Pira) flavus (Gmelin, 1791). This is the first record from the Korea, providing a description of the species with illustration for the shell morphology. Including the new recorded in this study, the family Ellobiidae contained six genera and 13 species in the Korea.

This work is a report about the first record of alcid species, Thick-billed Murre (Uria lomvia) in Korea. Four individuals of Thick-billed Murre captured by crab net were obtained in Deajin Port and near the Munam Port. three individuals of Thick-billed Murre searching food were observed at an area two miles away from Munam-Port. We describe characters of Thick-billed Murre with illustrations.

Desmotimmia mirabilis (Timm), a rarely known desmoscolecid nematode species, was discovered for the first time from the Yellow Sea off southwestern coast of Korea. This is the third record of the species, and the first report from the northwestern Pacific region. Redescription is prepared on the basis of a male specimen from South Korea.

Three isolates of Penicillium pimiteouiense were recovered from sandy beach soil samples in Penang Island, Peninsular Malaysia. All the isolates were identified based on morphological characteristics and phylogenetic analysis of internal transcribed spacer regions and ${\beta}$-tubulin gene. This is a first record of P. pimiteouiense in Malaysia.

A newly recorded species Orientomaera incisa Ariyama, 2020, belonging to the family Maeridae Krapp-Schickel, 2008, was collected from the sublittoral waters of the East Sea, Korea. Previously, only one species, O. brevispina (Kim and Kim, 1991), was reported in Korea. This species morphologically similar to O. brevispina however, the species can be easily distinguished from the O. brevispina by having two distinct teeth on palm of gnathopod 2. The newly recorded species is described and fully illustrated in the present study.

Herein, we report a new record of Arna bipunctapex (Hampson) and a new species, Euproctis fulvatus sp. nov. in Korea; both are Lymantriine moths. Arna bipunctapex is distinguished by a relatively large wingspan with two black dots and a small dot between these black dots in the apical region of a yellowish forewing. The male genitalia of A. bipunctapex can be distinguished by the lack of a process on the sacculus of valva while the female genitalia can be distinguished by an antrum that is basally flat with two lateral digitate arms. Euproctis fulvatus is distinguished by yellowish wings with a medially curved central fascia of the forewing. The male genitalia can be distinguished by the bifid, digitate uncus and the simple, square-shaped valva with a distal strong invaginated margin. The female genitalia can be distinguished by the long, medially twisted, ductus dursae with simple antrum posteriorly strongly sclerotized and ovate corpus bursae without signum. Larvae of E. fulvatus are distinguished by a black head with a pair of long, black, lateral tufts, dorsum with 10-11 white intersegmental dots and bright red setal warts on T2-A8, and bright red glands on A6 and A7.

To investigate the effects of haunch repair on the system seismic performance of steel moment-resisting frames (steel MRFs), a case study was conducted for a 13-story frame damaged during the 1994 Northridge earthquake. It was assumed that only those locations with reported damage would be repaired with haunches. A new analytical modeling technique for the dual panel zone developed by the author was incorporated in the analysis. Both the inelastic static and dynamic analyses did not indicate detrimental side effects resulting from the repair. As a result of the increased strength in dual panel zones, yielding in these locations were eliminated and larger plastic rotation demand occurred in the beams next to the shallow end of the haunches. Nevertheless, the beam plastic rotation demand produced by the Sylmar record of 1994 Northridge earthquake was still limited to 1.7% radians. The repair resulted in a minor increase in earthquake energy input. In the original structure, the panel zones should dissipate about 80%(for the Oxnard record) and 70%(for the Sylmar record) of the absorbed energy, assuming no brittle failure of moment connections. After repair, the energy dissipated in the panel zones and beams were about equal.

A marine algal species was collected from Sacheonjin, Gangneung located on the eastern coast of Korea during a survey of marine algal flora. This alga shares the generic features of Membranoptera belonging to the subfamily Delesserioideae and is characterized by the presence of combined features of membranous, monostromatic thalli attached by a solid discoid holdfast, blades with a conspicuous terete stipe-like midrib and microscopic lateral veins, entire margins, irregularly alternate to dichotomous branching, and obtuse apices growing apically. In a phylogenetic tree based on rbcL sequences, the Korean alga nests in the same clade with M. alata from the eastern North Atlantic. The genetic distance between both the sequences within the clade was calculated as 0.0%. Based on the morphological and molecular analyses, this Korean species is identified as the generic type, M. alata. This is the first record in the list of Korean marine algal flora.

The Aphis solanella, had been classified as a subspecies of Aphis fabae, is currently recognized as a separated species with A. fabae. The A. solanella is morphologically similar to A. fabae and has the same primary host, but there are differences in the range of the secondary host, physiological and ecological traits, so it has been suggested as a separated species. Since it had not been covered when recording the A. fabae at least including three subspecies in 2006 from South Korea, we recently collected and reconfirmed A. solanella in Busan. Therefore, we report the Aphis solanella as a new record with its description and illustrations.

A marine algal species was collected from the southern coast of Korea. This alga is characterized by a large and cartilaginous thallus, a dichotomous branching pattern, compressed axes, rare proliferations near the apex, and cystocarps protruded toward surface. In a phylogenetic tree based on rbcL sequences, this species nests in the same clade as Neodilsea yendoana as a terminal clade of the genus Neodilsea. The genetic distance between both sequences within the clade was calculated as 0.2% considered to be in the intraspecific range within the genus. Based on the morphological and molecular data obtained in the present study, this Korean species is identified as N. yendoana. This is the first record of the genus Neodilsea and N. yendoana in Korea.
