Two penaeid shrimps, Melicertus latisulcatus (Kishinouye, 1896) and Metapenaeopsis mogiensis mogiensis (Rathbun, 1902), collected from Jeju Island are described and illustrated with color photographs. Melicertus latisulcatus is previously known but without detailed description in Korean waters and M. mogiensis mogiensis is recorded for the first time. Distributional and morphological accounts of these two species are briefly discussed.

We found Rosa laevigata Michx., a newly alien plant in Songjinpo-ri, Jangmok-myeon, Geoje-si, Gyeongsang nam-do. Rosa laevigata is native to China, Taiwan, and Vietnam. It is reported as a naturalized species in Japan, South Africa, United States, and the Pacific Islands. Rosa laevigata is distinguished from R. multiflora by the large size of its flower. Its Korean name is 'Wang-jjil-re-na-mu' based on the large flower. Here, we provide precise description, taxonomic key to Korean Rosa species, illustrations and photographs of its habit.

We report a new distribution of Carex foraminata C. B. Clarke on the Korean Peninsula. This species was first reported in China and is distributed in Jiangxi and Zhejiang Provinces. We found this species on Hongdo Island in Heuksan-myeon, Shinan-gun, Jeollanam-do in Korea. Carex foraminata is similar to the related taxa C. brevispicula G. H. Nam & G. Y. Chung, C. chungii Z. P. Wang, and C. genkaiensis Ohwi in that its achenes are constricted in the middle part. However, C. foraminata is distinguished from C. brevispicula and C. chungii by its pistillate scale apexes, which are acute or shortly awned and by its achene apexes, which are shortly cylindrical; C. foraminata is distinguished from C. genkaiensis by its pistillate scale and achene shape. A precise description, illustration, photographs, and a key to related taxa are provided.

Tordylium maximum L. (Apiaceae), native to south, south-central Europe and southwest Asia and a rare alien plant in northern Europe, was newly found in Jeollabuk-do in Korea. Tordylium is clearly distinguished from other genera by having radiating petals, filiform bracts, linear bractlets, stalked mericarps with minutely vesicular dorsal face or strigose hairs, and an annual habit. Tordylium maximum is different from other species of the genus by its mericarps with smooth margins and 10-16 rays not contracted in fruit. T. maximum grows on dry and sunny grasslands. Here, we report the first occurrence of the genus Tordylium represented by T. maximum in Korea and provide a precise description, illustration, photographs of the species, and a taxonomic key to allied taxa in Korea.

During an investigation of unrecorded prokaryotic species in Korea, six unrecorded bacterial strains were isolated from soil samples collected from Uljin-gun. Based on a similarity search using the 16S rRNA gene sequence of the isolated strains and the construction of the neighbor-joining phylogenetic tree, five strains were identified to the genus Pseudomonas of the family Pseudomonadaceae, while one strain was identified as a species belonging to the genus Paenibacillus of the family Paenibacillaceae. The details of these unreported species, including gram staining reaction, colony and cell morphology, basic biochemical characteristics, strain ID, and isolation source, are described in the description of the strains.

Carex poculisquama $K{\ddot{u}}k$., recorded only in the literature in Korea, was confirmed to be distributed in limestone zones in the country. Carex poculisquama is most similar to species in the section Occlusae, such as C. ligulata Nees, but it differs in its rhombic-elliptic perigynium and by the presence of short hairs on the veins of its utricles. We provide here a description, illustrations, and photographs of C. poculisquama and a key to the species.

In March 2021, marine sediment from East Sea samples were suspended in a 2% NaCl solution, and serial dilution was performed in fresh marine and Reasoner's 2A agar. Isolated bacterial strains were identified based on 16S rRNA gene sequences, and showed at least 98.7% sequence similarity with previously reported bacterial species. Finally, seven bacterial strains which were validly published but not reported in Korea, were obtained. These isolates were allocated to the orders Bacillales and Flavobacteriales. The three Flavobacteriales strains are classified into the family Flavobacteriaceae. The other four Bacillales belong to the families Bacillaceae and Paenibacillaceae. The seven unrecorded bacterial strains in this study are classified into seven different genera, which are assigned to Mesobacillus, Paenibacillus, Gramella, Gillisia, Arenibacter, Fictibacillus, and Brevibacillus. During the investigation, the possibility of excavation of various unrecorded species in domestic marine sediment was confirmed. Gram-staining, cell morphology, physiological and basic biochemical characteristics, and phylogenetic analysis were performed in this study and provided in the description of each strain.

Semantic quirks about the concept of metadata are briefly probed. The reasons behind the conceptual drift are also reviewed. Regarding different formats of metadata, the rationale behind the creation of new formats, their characteristics in relation to MARC format, and problems and methods of conversion or integration of metadata are investigated as background study. RDF (Resource Description Framework) as an integration tool for different metadata standards and Metadata Registry as a candidate for the purpose are studied and the both are compared. It is concluded that two approaches are not mutually exclusive, rather they are complimentary.

The first record of Korean cyproideid amphipod, Cyproidea liodactyla Hirayama, 1978 is reported here with description and illustrations. This species has the following characteristics: the presence of dorsal keel of peduncle 2 on antenna 1, posterodistal process of ischium on gnathopod 1 and carpal process on gnathopod 2. In this study, the minor differences between the original description and our Korean specimens of Cyproidea liodactyla are discussed and a brief comparison to other related species such as C. serratipalma Schellenbeg, 1938 and C. robusta Ren, 2006 are suggested. In addition, a key to Korean species belonging to the family Cyproideidae is provided.
