송영보,이치훈,나오수,이영돈 濟州大學校 海洋硏究所 2002 해양과환경연구소 연구논문집 Vol.26 No.-

1995년 9월부터 1996년 8월까지 제주대학교 해양과 환경연구소가 위치한 함덕연안 조간대에서 채집한 울타리고둥, M. labio의 생식주기를 조사하기 위하여 생식소숙도지수의 변화와 생식세포 형성과정을 조직학적방법으로 조사하였다. 1. 울타리고둥의 생식소는 패각내 나선상 육질부 하단에서 꼬리돌기까지 간장부의 표면에 위치 하였다. 생식소가 성숙하면 암컷은 짙은 녹색, 수컷은 유백색을 띠고, 방출 후에는 암컷은 연갈색, 수컷은 연황색을 나타내었다. 2. 생식소숙도지수(GSI)는 암컷과 수컷 모두 수온이 상승하는 4월부터 상승하기 시작하여 9월에 암컷 0.47, 수컷 0.42로 최고치를 보이고 이후 10월부터 급격히 감소하였다. 저수온기인 1월에 GSI는 암컷과 수컷 모두 0.07로 최저치를 보였다. 3. 생식소의 발달 단계는 분열증식기(3월∼4월), 성장기(4월∼7월), 성숙기(8월∼9월) 그리고 방출 및 회복기(10월∼1월)의 연속적인 주기로 구분 할 수 있고, 주산란 시기는 10월로 추정 된다. 4. 울타리고둥, M. labio은 자웅이체로서, 성비는 약 1:1이었다(P>0.05). Reproductive cycle of thick liped monodont. Mondonta labio was invetigated by the histological observation of gonads and the gonadosomatic index(GSI). The thick liped monodont were collected at the intertidal zone of Hamdeok in Jeju-do from September, 1995 to August, 1996. Gonad of them was located o the surface of the liver below the stomachal caecum posterior spiral meat part of the shell. GSI value began to increase from May(as water temperature increased) and reached it's maximum value in September both male and female which were 0.42 and 0.47, respectively. It began to decrease from October thereafter, maintaining relatively in low value from January to March. The reproductive cycle of this species could be classified into four successive developmental stage; multiplication stage(March to April), growing stage(April to July), mature stage(August to september), spent and recovery stage(October to January). The main spawning period of M. labio appeared in October. The top shell, M. labio appeared to be gonochorism, neither sex reversal nor hermaphroditism. The sex ratio was approximately 1.0 : 1.0(P>0.05).

Ohjective : The primary purpose of this study was a replication of the effectiveness and tolerability of rispehdone in the treatment of patients with acute mania in very larger cohon in naturalistic treatment setting to extend the data on the effect and tolerability of risperidone in the treatment of patients with acute mania to Asian population. Methods : A total of 909 patients with DSM-TV criteria of bipolar disorder current manic and hypomanic episode, entered this large, open, multicentre study. The Young Mania Rating Scale (YMRS), Clinical Global Impression (CGI) and Simpson-Angus Rating Scale (SARS) were measured at baseline and weeks 1, 3 and 6, for the assessment of effectiveness and extra-pyramidal symptom (EPS). Results : This study showed statistically significant reduction of scores on the YMRS and CGI-s (mean change=-23.5±11.8, p<0.0001 ; mean change=-2.7±1.5, p<0.0001, respectively) from the baseline to the endpoint (week 6). Number of patients with 50% reduction or more in the YMRS and CGI-s scores was 693 (77.8%) and 630 (70.7%) at endpoint, respec-tively. There were no statistically significant increments of scores on SARS. Risperidone was generally well tolerated. Conclusion : The present larger open study demonstrates that hsperidone add-on therapy is effective and tolerable in treat-ment of bipolar disorder, replicating results in various controlled and uncontrolled studies from Western countries.

폐렴 구균(Streptococcus pneumoniae)에 의한 척수 경막외 농양 1예

이지영,위유미,손경목,기현균,문치숙,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

폐렴구균은 보통 폐렴이나 뇌막염을 일으키는 균으로 척수 경막외 농양을 일으키는 경우는 매우 드물다. 본 저자들은 폐렴 구균에 의한 척수 경막 외 농양을 경험하여 보고하는 바이다. 과거 건강했던 36세 남자 환자로 사다리에서 낙상한 후 요통 및 고열, 신경학적 이상으로 내원하여 자기 공명 촬영 결과 척수 경막 외 농양으로 진단받고 항균제 투여와 함께 응급 수술을 시행하였다. 농 배양 결과 페니실린 감수성인 폐렴 구균이 분리 되었고, 수술 요법과 항생제 투여 후 농양은 치유되었으나 신경학적 이상은 호전 없는 상태로 타원으로 전원되었다. Pneumonia and meningitis are the most frequent manifestations of pneumococcal infections. Pneumococcal spinal epidural abscesses have been rarely reported. Spinal epidural abscess by Streptococcus pneumoniae has been diagnosed among the patients with diabetes mellitus, alcoholism, corticosteroid therapy, intravenous drug use, chronic renal failure, AIDS, and history of spinal surgery. Recently, we experienced a case of pneumococcal spinal epidural abscess after spinal trauma. A 36-year-old male patient was admitted with back pain, fever, and paraplegia which occurred 5 days after the trauma. Spine MRI revealed spinal epidural abscess at the level from T2 to T9. He was treated with antimicrobial agents and surgical exploration for spinal epidural abscess. Pus culture grew S. pneumoniae which was susceptible to penicillin. Despite early surgical treatment, neurologic sequelae remained. Considering the high mortality and morbidity of pneumococcal spinal epidural abscess, early diagnosis and aggressive treatment including surgical intervention and antibiotics therapy should be implemented immediately.

무기체계 소프트웨어 규격화 누락여부 검증 방안 - 펌웨어 중심으로

송치훈(Chi-Hoon Song) 한국산학기술학회 2021 한국산학기술학회논문지 Vol.22 No.3

군에서 사용하는 무기체계의 경우 경제적이고 효율적인 조달 · 관리 및 유지를 위하여 국방규격을 제정하여 관리한다. 국방규격은 제품 및 용역에 대한 기술적인 요구사항과 요구필요조건의 일치성 여부를 판단하기 위한 절차와 방법을 서술한 문서로, 작성된 국방규격은 무기체계의 생산, 품질보증, 형상관리 등에 활용된다. 소프트웨어도 국방규격의 하나로 다른 국방규격(국방규격서, 품질보증요구서, 도면, 부품/BOM 목록)과 같이 작성되고 관리되나, 소프트웨어의 일부(또는 전부)를 포함하지 않고 규격화를 수행하는 경우가 있다. 이 경우 개발업체를 제외하고는 다른 업체들은 제품을 생산할 수 없어 경쟁계약이 제약될 뿐만 아니라, 승인 없이 업체가 임의로 소프트웨어를 변경할 수 있어 무기체계의 품질에도 큰 영향을 미친다. 따라서 소프트웨어의 규격화 누락 여부의 검증은 반드시 필요하나, 하드웨어 내부에 탑재되는 펌웨어의 경우 개발업체 외에는 규격화 누락 여부의 확인이 매우 어렵다. 본 연구에서는 실제 품질보증 업무 수행시에 활용할 수 있는 소프트웨어 규격화 누락 여부의 검증 방안을 제시하였으며, 이를 통해 무기체계의 효율적인 생산, 품질보증에 기여할 것이다. In the case of weapon systems used by the military, defense standards are applied for economical and efficient procurement, management, and maintenance. Defense specifications are documents describing procedures and methods for determining whether technical requirements for products and services are consistent and apply to the production of weapon systems, quality assurance, and configuration management. Software is also subject to defense specifications, and is documented and managed in the same way as other defense specifications. Sometimes it happened to be standardized without some(or all) software. In this case, a competitive contract is impossible and it may affect the quality of weapon systems because the manufacturer arbitrarily changes the software without prior approval. So, software standardization is required, but it is very difficult to verify for firmware installed in hardware. This paper proposed a verification method for g software standardization, and we expect it will contribute to the efficient production and quality assurance of weapon systems.

Effects of Different Light Spectra on the Oocyte Maturation in Grass Puffer Takifugu niphobles

Song-Hee Choi,Byeong-Hoon Kim,Sung-Pyo Hur,Chi-Hoon Lee,Young-Don Lee 한국발생생물학회 2018 발생과 생식 Vol.22 No.2

In order to examine the effects of four different light spectra (white, red, green, and blue) on the oocyte maturation, the change of reproductive parameters, via brain-pituitary-gonad (BPG) axis in grass puffer, were investigated. After exposure four different light spectra for 7 weeks, the abundance of gonadotropin-releasing hormone (GnRH) mRNA which is a type of seabream (sbGnRH) and two different subunit of gonadotropin hormones mRNAs, follicle-stimulating hormone (fshβ) mRNA and luteinizing hormone (lhβ) mRNA, were analyzed in the brain and pituitary. Histological analysis showed that the mature oocyte ratio in the green spectrum was higher than other light spectra-exposed groups. Gonadosomatic index (GSI) and oocyte developmental stage were also investigated in the gonad based on histological observations. GSI value with the presence of yolk stage oocytes was significantly increased in the green spectrum-exposed group when compared to that of the other light-exposed groups (white, red, and blue) (p˂0.05). The abundances of sbGnRH mRNA and fshβ mRNA in the green spectrum-exposed group were also significant higher than those of the other light spectra-exposed groups (p˂0.05). These results indicate that the maturation of oocyte in grass puffer can be accelerated by exposure to the spectrum of green. To better understand the molecular mechanism for the maturation of oocyte in grass puffer, further study examining the relationship between oocyte development and its related genes is required.
