한국산 새코미꾸리속 koreocobitis 어류의 골학적 연구
김익수,안정현,김병직 한국어류학회 2002 韓國魚類學會誌 Vol.14 No.1
미꾸라지과에 속하는 새미꾸리속 어류의 골격계를 경골과 연골로 구분지어 두개골, 상각 및 하악, 현수골, 설궁, 새궁, 척추골 및 부속골격, 전대 그리고 요대로 구분하여 관찰 · 기재하였고 근연군으로 생각되어 왔던 미꾸리속 및 기름종개속 어류의 기존에 보고된 골학적 특성과 비교하였다. 대부분의 골격에 있어서 미꾸리아와 어류의 다른 속의 골격계와 거의 일치하였는데, 새궁에서 제 3기새골이 연골로서 신장되어 잇는 점, 하새골이 모두 4쌍으로 제 4하새골이 크기는 작지만 연골로서 존재한다는 점, 그리고 인새골이 모두 3쌍으로 제3인새골이 연골이지만 뚜렷하게 존재한다는 점에서 차이가 있었다. 새코미꾸리와 얼룩새코미꾸리의 2종 간에는 측사골에 있는 측돌기의 위치와 견갑골의 돌기의 크기를 제외하고는 뚜렷한 차이가 나타나지 않았다. 한편, 그 동안 많은 논란이 있었던 본 속의 분류학적 위치에 대해서는 전두골이 부접형골과 마나지 않고, 현수골에 metapterygold-quadrate fenestra가 존재하는 점에서 미꾸리속보다는 기름종개속 어류와 근연인 것으로 사료된다. The skeletal system of the Korean endemic genus Koreocobitis is described and figured in detail, and discussed with previous reports about two related genera. Misgurnus and Cobitis. Although most skeletal characteristics of Koreocobitis accord with those of the other cobitid fishes, there were differences in the number of hypobranchial and pharyngobranchial bones and in having the fourth cartilaginous basibranchial bearing a thread-like cartilage extending posteriorly. The position of the lateral process on the lateral ethmoid and the size off the process in the scapula were different between the two species K. rotundicaudata and K. naktongensis. On the basis of two characters, frontal not contacting with parasphenoid and presence of metapterygoid-quadrate fenestra, the genus Koreocobitis seems to be closely related to Cobitis rather than to Misgurnus.
Internucleotide Phosphotriester Bond 형성에 따른 Arylsulfonyl azolide계 축합시약의 반응성
이상직,김대연,송병수 嶺南大學校附設 基礎科學硏究所 1985 基礎科學硏究 Vol.5 No.-
Arylsulfonylimidazoles, arylsulfony-1,2,4-triazoles and arylsulfonyl-3-nitro-1,2,4-triazoles were synthesized and employed in the formation of a phosphotriester bond between appropriately protected monodeoxyribonucleotides. New condensing agents, benzenesulfonyl-3-nitro-1,2,4-triazole, and p-toluenesulfonyl-3-nitro-1,2,4-triazole were found to be excellent in the dideoxyribonucleotide synthesis via the phosphotriester method.
Deoxyribonucleoside의 보호와 di-p-Methoxytrityl기의 제거에 대한 Alcohol류의 효과
이상직,송병수,김대연 嶺南大學校附設 基礎科學硏究所 1984 基礎科學硏究 Vol.4 No.-
5'-O-Dimethoxytritylthymidine and N-benzoyl-5'-O-dimethoxytrityldeoxyade-nosine were synthesized from the corresponding deoxynucleosides and some factors influencing their yields were also investigated. To remove the dimethoxytrityl group from 5'-O-Dimethoxytritylthymidine and N-benzoyl-5'-O-dimethoxytrityldeoxyadenosine, ZnBr₂/CH₃NO₂, ZnBr₂/CH₃NO₂in the presence of alcohols, and CH₃COOH/CH₃NO₂systems were employed. The rates of the detritylation as well as the extent of side reaction in these systems were estimated and the effect of alcohols on the reactions was discussed.

p-type α-SiC(4H, 6H, 15R polytype)를 사용하여 다공질 실리콘(porous silicon; PS)의 제작방법과 유사하게 HF/H₂O/C₂H??OH 용액에서 전기화학적으로 에칭을 하여 광발광 특성을 가지는 다공질 실리콘 카바이드(porous silicon carbide; PSC)를 제작하였다. PSC의 다공질의 분포는 전류밀도가 증가할수록 증가하고 다공질의 크기는 감소하였으며 광발광(photoluminescence; PL) 스펙트럼의 분석을 통해 전극 표면에서의 산화반응은 공급되는 전자의 양과 전류밀도에 의존하며 전류밀도가 증가할수록 전극의 산화반응은 억제된다는 결과를 얻었다. Porous silicon carbide(PSC) having photoluminescence(PL) can be prepared by a technique very similar to that used in porous silicon preparation, by electrochemical etching of crystalline p-type α-SiC(4H, 6H, 15R polytype) in ?? solution. The results show that porous distribution increase with increasing of the current densities while pore size decrease with that. Through the PL spectra analysis anodic oxidation of electrode surface was dependent on the amount of provided electrons and the current densities and inhibited with increasing of the current densities.

<P>Congenital cytomegalovirus (cCMV) infection is a common congenital infection that causes sensorineural hearing loss (SNHL). Despite its substantial impact on public health and cost burden, epidemiology and clinical features of CMV-related SNHL have never been reported in the Korean populations. This study investigated the detailed audiologic phenotypes of cCMV infection to see if a specific SNHL pattern is associated with a particular clinical setting. A total of 38 patients with cCMV infection were studied retrospectively. Patients were classified into three groups with distinct demographics: clinically driven diagnosis (n=17), routine newborn CMV screening according to the NICU protocols (n=10), or referral to ENT for cochlear implant (CI) (n=11). The incidence of cCMV infection was 3.6%, showing 33.3% of SNHL among cCMV patients, 38% of asymmetric hearing loss, 29% of late-onset hearing loss, and diverse severity spectrum in patients with CMV-related SNHL. CI recipients with CMV-related SNHL showed a significantly improved speech perception. Surprisingly, in 36.4 % of CI implantees, initial audiological manifestation was significant asymmetry of hearing thresholds between both ears, with better ear retaining significant residual hearing up to 50dB. CMV turns out to be a significant etiology of SNHL, first to date reported in the Korean pediatric population. Analysis of audiologic phenotypes showed a very wide spectrum of SNHL and favorable CI outcomes in case of profound deafness. Especially for the patients with asymmetric hearing loss, close surveillance of hearing should be warranted and CI could be considered on the worse side first, based on the observation of rapid progression to profound deafness of better side.</P>
First Record of the Gobiid Fish, Eviota prasina from Korea
Kim, Byung-Jik,Go, You-Bong 한국어류학회 2003 韓國魚類學會誌 Vol.15 No.1
제주도 남제주군 성산 일대의 조간대 어류상을 조사하는 과정에서 망국어괴 풀비늘망둑속 Eviota의 한 종인 E. prasina 4개체를 채집하였다. 본 종은 두부감각관 개공 중 intertemporal pore가 없고, 가슴지느러미 분지기조수가 5~8개이며, 배지느러미 연결기조막이 깊게 파여있고, 미병부 중앙 후단부에 1개의 흑점과 몸의 후방 복부에 5개의 흑점이 있으며, 후두부와 가슴지느러미 기부의 흑점이 불문명한 점에서 동일속의 풀비늘망둑과 쉽게 구별된다. 본 종의 국명은 ‘남방풀비늘망국’이라 명명하였다. Four specimens of the gobiid fish, Euiotaprasina (Klunzinger, 1871) were collected from the shallow tide pools located at Seongsan-ri, Seongsan-eup, Namjeju-gun, Jeju-do, Korea. We here describe these specimens as the first record of the species from the Korean waters, and name it "Nambang-pulbineul-mangduk" in Korean. E. prasina differs from E. abax, which is a previously known species from Korea, in lacking of intertemporal pore of cephalic sensory pore system, presence of a dark caudal peduncle spot, presence of five dark spots on ventral midline of trunk, having of 5-8 branched pectoral fin rays, and basal membrane of the pelvic fin reduced.
