The Eyebar goby, Gnatholepis cauerensis is reported firstly from Korea, based on four specimens (36.3~47.1 mm in SL) collected at depth range of 12~16 m in the southern coastal waters of Jejudo Island, Korea. They are characterized by having mostly ctenoid scales on body, head including cheek, opercle, and middle of predorsal region with cycloid scales, and a unique coloration of yellow blotch with marginally black marking above pectoral fin base as well as transverse black bar below eye. A new Korean name, "Geom-eun-nun-ddi-mang-dug", is proposed for the species.

A single specimen of Strophidon sathete (1,302 mm in total length), belonging to the family Muraenidae, was collected in a danish seine off the southern coast of Jejudo Island in April, 2019 for the first time. It was characterized by having unpatterned coloration and thin body, snout slightly rounded, three superorbital pores, four infraobital pores, and six mandibular pores. This species is distinguishable from morphologically similar Gymnothorax albimarginatus inhabiting Korean waters by having all fins dark (vs. fins dark posteriorly with white margin for latter), body depth 1.8~3.1% in total length (vs. 3.2~5.7%), and no dark band on head in less than 50~70 cm (vs. exist). We add Strophidon sathete to the Korean fish fauna and propose a new Korean name, "Ga-neun-gom-chi" for the species because the body is relatively thinner than other similar moray species (G. albimarginatus) in Korea.

Six specimens (151.4~171.2 mm in standard length) of the poacher Aspidophoroides monopterygius were collected by Danish seine net in the coastal waters off Samcheok and Gangneung, the East Sea, Korea. This species is characterized by a slender body, one dorsal fin, terminal mouth, no barbel on the head, and a pair of nasal spines on the snout. It differs from Anoplagonus occidentalis Lindberg in having a nasal spine. We describe it as the first record within the Korean fish fauna, and propose the new Korean name "Ak-eo-jul-go-gi" for this species.

Electroencephalograhic(EEG)는 심리학의 영역에서 인간 두뇌의 활동을 측정 기록하는데 오래 전부터 사용하였다. 과학의 발달함에 따라 점차적으로 인간의 두뇌에서 감정을 조절하는 기본적인 영역들이 밝혀지고 있다. 그래서 인간의 감정을 조절하는 인간의 두뇌 활동 영역들을 EEG를 이용하여 측정하였다. 본 논문에서는 EEG의 신호들과 몸짓을 이용해서 감정을 인식하였다. 특히, 기존에 생체신호나 몸짓 중 한 가지만을 이용하여 각각 실험해서 감성을 인식하였지만, 본 논문에서는 EEG 신호와 몸짓을 동시에 이용해서 피 실험자의 감성을 인식하는 실험을 하였다. 실험결과 기존의 생체신호나 몸짓 한 가지만을 가지고 실험했을 때의 인식률 보다 더 높은 인식률을 보임을 알 수 있었다. 그리고 생체신호와 몸짓들의 특징 신호들은 강화학습의 개념을 이용한 IFS(Interactive Feature Selection)를 이용하여 특징 선택을 하였다.

Two hypotrichous ciliates inhabiting the representative terrestrial habitats of Jindo Island, Holostichides chardezi Foissner, 1987 and Rigidocortex octonucleatus (Foissner, 1988) are found from Jindo Island. These two species are newly recorded from Korea. The description was based on the observation of living specimens, protargol impregnated specimens and biometric analysis. The morphological variations among the populations of these species were investigated with morphometry. The diagnostic characteristics of these species are as follows: Holostichides chardezi : elongate body flexible and twisted, yellowish subpellicular granules scattered entire cortex, adoral zone of membranelles covering about $28\%$ of body length, left and right rows of mid-ventral cirri paired, left row ended at buccal vertex and right row extending to center of body, no transverse cirri, both marginal rows of cirri not confluent at posterior end, 28-42 macronuclei and 1-5 micronuclei scattered entire body. 3 caudal cirri and 4 dorsal kineties. Rigidocortex octonucleatues: elongate-oval body rigid and not contractile, yellowish cytoplasmic crystals and fat globules densely packed, adoral zone of membranelles covering about $40\%$ of body length, 5 transverse cirri, both marginal rows of cirri not confluent at posterior end, 8 macronuclei longitudinally arranged in median of cell, 3 caudal cirri and 7-10 fragmented dorsal kineties.

Two specimens of the syngnathid Syngnathoides biaculeatus were collected from the coastal waters of Geoje Ialand and Tongyeong, Korea, represent first record of the species and the genus from Korea. This species is characterized by the following combination of characters: caudal fin absent; opercle without keel; superior and inferior trunk ridges continuous with their respective tail ridges; lateral trunk ridge deflected dorsal behind anal ring. Tail shorter than head and body hexagonal in its subdorsal part, posterior quadrangular, rapidly tapering, without caudal fin, prehensile. Head essentially in line with longitudinal axis of body or bent very little. New Korean names are proposed, "Jal-pi-sil-go-gi-sok" for the genus Syngnathoides, and "Jal-pi-sil-go-gi" for S. biaculeatus.

사람 몸의 약 70%를 구성하고 있는 물에 대한 현대인의 관심은 줄어만 가고 최근 들어 늘어가는 카페들과 각종 재료를 첨가한 달콤한 음료들이 생활 속에 깊숙이 파고 들고 있다. 아침에 일어나자마자 마시는 것은 물이 아닌 커피, 식사 후 지인들과의 대화에 함께 하는 것 또한 물이 아닌 카페 음료들, 각종 패스트푸드 섭취와 함께 마시는 탄산음료들은 물이 설 자리를 빼앗고 있다. 이러한 생활 습관은 현대인들의 물 섭취량 감소를 촉진하며 건강의 적신호를 보내고 있다. 이 어플리케이션의 목적은 지금의 위험 상황을 자각하지 못하는 현대인들을 위해 다양한 서비스를 통해 자동으로 물 섭취를 권장하고자 한다. 개개인에게 맞춤형 서비스를 제공함으로써 체내의 물 부족 현상에 대한 자각심을 일깨우고 스스로 점검할 수 있게 한다. 멀티 테넌트 환경으로 구현하고자 BaaS 플랫폼을 통해 서버 구축, DB 설계, 서비스 기능 개발 연구를 진행하고 모든 리소스가 공유되어 사용자에게 물 섭취 기록, 기록을 볼 수 있는 타임라인, GPS 를 활용한 주변의 물 위치 정보를 제공한다.

A shrimp goby, Amblyeleotris japonica is reported firstly from Korea, based on a single specimen (70.3 mm in SL) collected at a depth of 14 m in the southern Jejudo Island. The species is characterized by having a lower number of scales in longitudinal series, a rather compressed body, anterior limit of opercular opening located below between posterior margin of eye and preopercle, second dorsal fin with a single spine and 13 soft rays, anal fin with a single spine and 14 soft rays, and five brownish vertical bands on lateral body between head and caudal peduncle when fresh. New Korean names, "Se-u-but-i-mang-dug-sog" and "Bulg-eun-dong-gal-se-u-but-i-mang-dug", are proposed for the genus and the species, respectively.

Researchers in the field of psychology used Electroencephalographic (EEG) to record activities of human brain lot many years. As technology develope, neural basis of functional areas of emotion processing is revealed gradually. So we measure fundamental areas of human brain that controls emotion of human by using EEG. Hands gestures such as shaking and head gesture such as nodding are often used as human body languages for communication with each other, and their recognition is important that it is a useful communication medium between human and computers. Research methods about gesture recognition are used of computer vision. Many researchers study emotion recognition method which uses one of physiological signals and gestures in the existing research. In this paper, we use together physiological signals and gestures for emotion recognition of human. And we select the driver emotion as a specific target. The experimental result shows that using of both physiological signals and gestures gets high recognition rates better than using physiological signals or gestures. Both physiological signals and gestures use Interactive Feature Selection(IFS) for the feature selection whose method is based on a reinforcement learning.
