  • Two specimens of Omobranchus fasciolatoceps (33.8~46.7 mm SL) were collected from oyster reefs of Osu-ri, Geoje-myeon, Geoje-si, Gyeongsangnam-do, Korea. This species is characterized by having 32~34 dorsal fin rays, 24~25 anal fin rays, 13 pectoral fin rays, 2 interorbital pores, 8 circumorbital pores, 5~7 lateral line tubes, fleshy crest on head and sexual dimorphism in female that have lost the posterior canines in both jaw. We propose the new Korean name, "Ppul-be-do-ra-chi", for the species.

  • Three juvenile specimens (38.8~51.5 mm SL) of the opistognathid fish, Opistognathus hongkongiensis Chan were collected off the Jeju Island, southern Korea. O. hongkongiensis is characterized by having a large mouth, dark brown vertical bands on sides, and yellow dorsal fin without a black blotch. We described it as the first record to Korean fish fauna, and proposed the new Korean name, "Jul-hu-ak-chi" for this species.

  • A single specimen (59.3 mm in SL) of the family Gobiesocidae was collected from the northern coast of Jeju Island, Korea. It was identified as Lepadichthys frenatus by its having dorsal and anal fins with 17 and 13 rays, respectively, both fins connected to the caudal fin, and a reddish-brown body color. We describe the specimen as the first record from Korea, and propose a new Korean name "keun-ip-hak-chi" for the species.

  • A single bothid specimen (113.9 mm in standard length) was collected by bottom trawl from southern Jejudo Island, Korea. It was easily identified as Kamoharaia megastoma (Kamohara, 1936), based on extremely large mouth. The species is characterized by maxillary extending beyond eyes, three pairs of long curved canines on lower jaw, tip of vomer projecting into mouth cavity, blackish pectoral fin, and blind side without lateral line. We described it as the first record to Korean fish fauna, and proposed the new Korean name, "Keun-ip-dung-geul-neop-chi" for this 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.

  • Based on a single adult and two juvenile fishes collected from the coastal waters of Jeju Island, Scartella emarginata was redescribed as the first reliable record from Korea. The species is characterized by having a median fringe of cirri on head, short branched supraorbital cirrus, and by lacking canine teeth on both jaws.

  • Complex odontomas consist of a conglomerate mass of enamel, dentin and cementum which bears no anatomic resemblance to a tooth. The majority of these lesions are completely asymptomatic, being discovered on routine radiographic examination or when films are taken to determine the reason for tooth eruption failure. Compound odontomas seldom cause bony expansion, but complex odontomas often cause slight or even marked bony expansion. Complex odontomas are mostly associated with permanent teeth and very rarely associated with deciduous teeth. They are usually located in the first-or second-molar areas of the mandible. This report presents a case of a patient with impaction of a maxillary primary canine by a complex odontoma in which surgical excision of the lesion was performed. And the primary canine was repositioned right under gingival level for spontaneous erution. Follow-up after six months showed spontaneous eruption ofthe repositioned maxillary primarycanine.

  • Unlike a medical doctor, a dentist performs all the tasks necessary for diagnosis and treatment of a disease all by himself. To increase the diagnostic accuracy, dentists need an efficient working environment providing much more integrated information of clinical data and radiographic image. In this paper, we propose an integrated environment for the dental hospital. It provides paperless and filmless hospital environment by integrating seamlessly three major operations for the dental hospital including patient record generation and management, clinical image acquisition and analysis, and treatment planning and simulation. This system also allows clinicians to provide more predictable dental care for the patients by supporting instant access to all the clinical data and quantitative data analysis.

  • The fibroma is the most common benign soft-tissue tumor found in the oral cavity and most commonly occurrs in sites predisposed to irritation or trauma. Treatment is conservative surgical excision. Seldom does the lesion recur. A 14-year old girl was referred to the Department of Pediatric Dentistry for evaluation and management of a mass on the palate. The patient's parents reported the slow growth of this soft tissue lesion over a 6-month period. A history of trauma or irritable habits was denied. Clinical examination revealed an asymptomatic, soft, pedunculated elevation of mucosa, measuring 3cm in diameter. Excisional biopsy of the lesion supported a diagnosis of fibroma. There have been no signs of recurrence during follow up of 4 years after surgical intervention. The clinical picture, pathology and management of the case are described, and the differential diagnosis and treatment are discussed.

  • 본 연구는 치과진료실의 실내 공기질에 영향을 미치는 요인과 종사자의 실내자각증상과 관련성을 조사하여 치과위생사 개인의 발전과 건강 증진에 필요한 기초자료를 마련하고자 본 연구를 시행하였다. 전국(서울, 경기, 대구, 포항)의 종합병원, 치과병원, 치과의원의 치과위생사 210명을 대상으로 2011년 10월 1일부터 20일까지 자기기입식 설문지 조사를 시행한 후 회수하여 응답이 불분명한 5명을 제외한 205명에 대해서 분석 하였다. 수집된 자료는 SPSS WIN 15.0 프로그램을 이용하여 분석하였다. 그 결과 근무 중 휴식시간 유무별로는 근무 중 휴식시간이 없는 치과위생사가 67.3%로 높은 분포를 보였고, 건물 밖 외출 여부별로는 때때로가 54.6%로 절반 이상을 차지하였으며, 건물 밖 외출횟수별로는 1회 86.1%로 대부분을 차지하였으며, 근무기관의 계절별 자연환기 정도별로는 봄, 여름, 가을, 겨울 모두 1일 2회 이내가 절반 이상을 차지하였으며, 다음으로 1일 4회 이내 19.0%, 기타 9.8%, 1일 10회 이내와 하루 종일 2.4% 순이었다. 실내자각증상 호소율에 대해 살펴본 결과는 4점 만점 중 전체 평균이 2.45로 나타났다. 먼저 영역별로는 평균이 '목증상'과 '눈증상'이 각각 2.54로 가장 높았으며, 문항 중에는 평균이 '눈이 잘 피로해진다'가 3.00으로 가장 높게 나타났다. 근무환경 특성에 따른 실내자각증상은 야간진료 여부별로는 야간진료를 하는 치과위생사가 그렇지 않은 치과위생사보다 실내자각증상이 낮았으며, 야간진료 여부에 따라 유의한 차이를 보였다(t=2.07, p<.05). 실내자각증상과 직무스트레스의 관계는 물리환경(r=.259, p<.001)과 직무요구(r=.311, p<.001), 관계갈등(r=.172, p<.05), 조직체계(r=.158, p<.05), 보상 부적절(r=.197, p<.01), 그리고 직무스트레스(r=.275, p<.001)와 통계적으로 유의한 상관관계를 보였다.
