Four individuals of Lipolagus ochotensis larvae (13.4~21.3 mm SL), belong to the family Bathylagidae, were collected by a Bongo net from the southern waters off Jejudo Island, Korea in February to March 2018. L. ochotensis is characterized by a elongated and compressed body, the eye stalks, series of melanophores on posterior of body, dorsal fin origin above the middle of the body. A molecular analysis based on 625 base pairs sequences in the mitochondrial DNA cytochrome c oxidase subunit I region shows that specimens were closely matched to adult L. ochotensis (genetic distance=0.024). We report the first record of family Bathylagidae, genus Lipolagus, L. ochotensis in Korean waters, and suggest their new Korean names, "Sim-hae-bing-eo-gwa", "Geom-eun-bing-eo-sok", and "Geom-eun-bbyam-bing-eo", respectively.

A single specimen of the genus Plectorhinchus (Family: Haemulidae) was collected from the coastal waters around Jejudo Island on November 1, 2017 by a longline. The specimen was identified as Plectorhinchus vittatus by the morphological characters as follows: eight black vertical stripes on the body, scattered polka dots on the dorsal, anal and caudal fins. It is clearly distinguished from the congeneric species, P. lineatus, which is morphologically very similar to P. vittatus, in the number of gill rakers, stripes on the abdomen, and black patterns on the base of the pelvic fin. In this study, the occurrence of this species has been newly revealed at higher latitudes, suggesting the expansion of the northern distribution limit. Following Lee et al. (1999), we propose its Korean name as "Chu-sa-eo-reum-dom".

This is the first report of Trachinotus blochii (Perciformes: Carangidae) from Korea. Single specimen (89.8 mm SL) was collected by seine fishing from the coastal waters of Busan on 13 September, 2023 and two specimens (29.53~30.78 mm SL) were collected by scoop net from Jejudo Island, Korea. This species is distinguishable from the most similar species, Trachinotus blochii as follows: it has the no black spots (vs. black spots in T. baillonii), 21~25 dorsal fin rays (vs. 18~20), and 20~24 anal fin rays (vs. 16~18). In order to confirm their taxonomic status, their mitochondrial DNA cytochrome c oxidase subunit I sequences were obtained and compared with those of carangid species recorded in the NCBI database. As a result, it was perfectly matched to T. blochii, and differed from T. baillonii (genetic distance=5.46%). We propose a Korean name, "Mu-jeom-mae-ga-ri", for the species.

In May 2020, a single larval specimen (5.14 mm in total length) was collected from the southeastern sea of Jeju Island of Korea using bongo net. The specimen was identified as Lepidotrigla longifaciata based on mitochondrial DNA cytochrome c oxidase subunit I sequences. The morphological traits of the L. longifaciata larva are as follows: a long snout, a large mouth, large fan-shaped pectoral fins, and black melanophores scattered on the abdominal cavity and nape. We propose the new Korean name 'Gin-meo-ri-dal-jae' for this species, which was first discovered in Korea.

This is the first report of Apogon erythrinus (Perciformes: Apogonidae) from Korea. A single specimen (33.6 mm SL) was collected by a fish pot from the coastal waters of Jeju-do Island on 28 October 2009. This species is characterized by having 5~6 predorsal scales, 7~9 developed gill rackers, end of second dorsal fin spine not reaching the middle of second dorsal fin base when depressed, and posterior margin of body scales reddish-brown. To confirm the correctness of species identification, the DNA cytochrome c oxidase subunit I sequence was obtained from the sample and compared with those of cardinalfish species recorded in the NCBI database. As a result, it was well-matched to A. erythrinus. We newly added this species to the Korean fish fauna and proposed a new Korean name, "Kueun-nun-eol-ge-bi-neul" because the eyes are large compared to its body.

Two specimens of Ostorhinchus fleurieu (54.25 mm, 55.64 mm SL) were collected by angling for the first time from Seogwipo-si, Jejudo Island, Korea on September and November 2023. This species is readily distinguished from the congeneric species, O. aureus by the number of total gill rakers (19~23 in O. fleurieu vs 22~27 in O. aureus) and shape of dark stripe on caudal peduncle (poorly defined, barrel shaped in O. fleurieu vs. well-defined, hourglass shaped in O. aureus). A total of 560 base pairs of mitochondrial DNA cytochrome c oxidase subunit I region of our two apogonid individuals perfectly matched with those of O. fleurieu (MT076481) registered in NCBI. Here, we propose the new Korean name "Kkoch-dong-gal-dom" for the species O. fleurieu.

A single specimen belonging to the family Carangidae was first collected by angling in Seogwi-dong, Seogwipo-si, Jeju-do on 16 October 2023. This individual was identified as Caranx papuensis Alleyne & MacLeay based on morphological traits as following: lateral line gently curving below the first dorsal fin, presence of scaleless area on the thorax, and gill rakers 26. A total of 619 base pairs sequences of the mitochondrial DNA cytochrome c oxidase subunit I region was analyzed, and we found it closely matched to the Japanese C. papuensis (K2P distance=0.54%). We propose its new Korean name "Hwang-jul-jeon-gang-i" based on a yellow band along the lateral line.

Acupuncture is increasingly being used in Asian countries and is generally considered a relatively safe procedure. However, adverse events have been reported consistently. Therefore, clinicians should be aware of the possibility of acupuncture-related complications and should actively treat serious cases. We report a case of an acupuncture-induced large abscess in the retroperitoneal cavity and thigh muscles treated with percutaneous catheter drainage, surgical incision, and drainage.

Morphological characters of section Atratae of the genus Carex (Cyperaceae) were reexamined. The epidermal patterns of perigynium, achene and leaf were investigated using by a scanning electron microscope (SEM) and a light microscope (LM). Morphological characters such as length and width of stem, leaf, bract, spike, scale, perigynium and achene, and shape of cross-sectioned stem, and leaf, spike, scale, apex of scale, perigynium, beak of perigynium and achene, and epidermal pattern of perigynium, achene and leaf (shape of fundamental epidermal cell and cell wall, type of silica body, shape of beak epidermal cell and cell wall in perigynium, subsidiary cell shape, size and frequency of stomatal complex of leaf) were useful for the identifications of the observed seven taxa. C. gmelinii, C. hancokiana and C. peiktusani have been confused each other due to similar morphological characters. Howerever these taxa were distinct with respect to shape of scale, apex of scale, perigynium, type of silica body, frequence of stomatal complex, subsidal cell shape, and epidermal patterns of achene and leaf.

In this study, we monitored the raw materials in home-meal replacement (HMR) products, which have shown more than 63% growth in market size for two years. A total of 89 HMR products were purchased and the DNA barcodes of 112 raw materials in the product samples were analyzed. In order to identify the raw material species, a primer set specific for the 16S ribosomal RNA region of each raw material species was amplified. The amplicon was purified and sequenced, and then used to perform a BLAST search provided by the National Institutes of Health (NIH). The species of the raw material was determined by comparing the nucleotide sequences of the species registered in GenBank with identity and match score. Twenty-four species and three genera were identified from 112 raw materials. Three genera were identified at the genus level because a large number of species belonging to the same genus exist within 98% of the identity criteria. The results of the determination were compared with the available raw materials suggested in the Korea Food Code to determine the Korean name and availability of the foods. Six non-listed species were determined to be edible according to information provided by influential domestic and foreign organizations.
