Colletotrichum panacicola isolates were obtained from anthracnose lesions of Korean ginseng and compared with four Colletotrichum species in morphology, molecular phylogeny and pathogenicity. Based on morphological characteristics, C. panacicola was easily distinguished from Colletotrichum gloeosporioides but not from Colletotrichum higginsianum, Colletotrichum destructivum and Colletotrichum coccodes. A phylogenetic tree generated from ribosomal DNA-internal transcribed spacer sequences revealed that C. panacicola is remarkably distinguished from C. gloeosporioides and C. coccodes but not from C. higginsianum and C. destructivum. However, molecular sequence analysis of three combined genes (actin + elongation factor-1α + glutamine synthatase) provided sufficient variability to distinguish C. panacicola from other Colletotrichum species. Pathogencity tests showed that C. panacicola is pathogenic to Korean ginseng but not to other plants. These results suggest that C. panacicola is an independent taxon distin-zguishable from C. gloeosporioides and other morphologically similar Colletotrichum species.

Systemic sclerosis is an intractable disease characterized by diffuse fibrosis, vasculopathy and immunologic abnormalities. Diffuse type of systemic sclerosis shows a variety of symptoms according internal organs involvement such as lung, heart, kidney and gastrointestinal system. Gastrointestinal involvement is very frequent and one of major cause of increasing mortality. There are no sustained and effective therapies to treat a active diffuse gastrointestinal involvement in systemic sclerosis. Although immunoglobulin is commonly used in the treatment of other autoimmune diseases, but the effect for the treatment of gastrointestinal involvement in systemic sclerosis has challenge. Here we report a case of treating with immunoglobulin in severe cough causing uncontrolled gastrointestinal involvement in diffuse type of systemic sclerosis. Keywords: Systemic sclerosis; gastrointestinal involvement; immunoglobulin

This study estimates the financial value of living stability, bequest and resident stability at the time of purchasing reverse mortgage. The financial value of living stability increase but that of resident stability decreases with the age of borrower. Increases in survival of 70-year-old are directly related to the present value of living and resident stability, but inversely related to that of bequest. With increases in mortgage rate, the present value of bequest decreases but that of resident stability increases. With increases in housing prices, both the present value of bequest and that of resident stability increases. This study is significant that it assesses the present value and financial effects of bequest and resident stability in addition to monthly payment. 본 연구는 주택연금 가입 시 주택가격을 생활안정, 유산 및 거주안정 현재가치 등 세 요소로 나누어 가입연령에 따른 각 요소별 재무적 가치를 분석하였다. 생활안정의 현재가치는 고연령 가입자일수록 증가한 반면, 거주안정의 현재가치는 저연령 가입자일수록 그 가치가 점점 증가하였다. 또한 70세 가입자를 대상으로 생존확률, 대출금리, 주택가격상승률에 변화에 따른 재무적 가치의 변화를 분석한 결과, 장래 생존확률의 개선효과 반영 시 생활안정 및 거주안정의 현재가치는 증가하는 반면, 유산의 현재가치는 적어지는 것으로 나타났다. 또한, 대출금리 상승 시 유산의 현재가치는 줄어드는 반면, 거주안정의 현재가치는 증가하는 것으로 나타났다. 마지막으로 주택가격이 상승할 경우에는 유산 및 거주안정의 현재가치는 상승하였다. 본 연구는 주택연금 월지급금 이외에 유산 및 거주안정의 현재가치를 측정하고, 이에 대한 재무적 효과를 제시했다는 점에서 차별성이 있다고 할 수 있다.

“UNCITRAL 전자양도성기록 규정안”에 대한 고찰 - 제47차 UNCITRAL WG IV 논의를 중심으로 -
최경진 국제거래법학회 2013 國際去來法硏究 Vol.22 No.1
UNCITRAL has affected to many countries through its various texts including the Model Law on Electronic Commerce, the Model Law on Electronic Signature, and Electronic Communications Convention, etc. Korea as a leading country in the field of electronic commerce adopted many provisions from UNCITRAL texts. i.e Framework Act on Electronic Document and Electronic Transaction, Act on Electronic Signature. The ongoing issue about new “Draft provisions on electronic transferable records” would have high possibility to give an impact to many countries. The draft provisions was first introduced in the 47th Working Group Ⅳ(New York, 13-17 May 2013). Electronic transferable record means “a record used in an electronic environment that is capable of transferring the rights incorporated in the record through the transfer of the electronic record itself.” Once the draft provisions will be enacted, it is expected to have big effect to Korea too. Of course, it takes so long time to finish legislation process in UNCITRAL. However, even discussion about draft provisions on electronic transferable records would be helpful for Korea to contemplate new legislation or amendment to existing laws. This paper is expected to contribute to make it possible to legislate integrated online and offline transferable records system.

1.5-비트 비트 셀을 이용한 새로운 구조의 CMOS 전류모드 아날로그-디지털 변환기
최경진,이해길,나유찬,신홍규 한국음향학회 1999 韓國音響學會誌 Vol.18 No.2
본 논문에서는 CSH(Current Sample-and-Hold)와 CCMP(Current Comparator)로 구성된 1.5-비트 비트 셀을 이용한 새로운 구조의 CMOS IADC(Current-mode Analog-to-Digital Convener)를 제안한다. 전체적인 IADC의 선형성 향상을 위하여 CFT(Clock Feedthrough)가 제거된 9-비트 해상도 CSH를 설계하여 각 비트 셀 전단에 배치하였다. 제안한 IADC를 구성하는 비트 셀은 2개의 래치 CCMP를 사용하기 때문에 디지털 교정 로직이 간소화되고 소비전력이 감소된다. 또한 IADC를 구성하는 모든 블록들의 회로는 MOS 트랜지스터로만 설계되었기 때문에 혼성모드 집적화에 유리하다. 제안한 IADC를 현대 0.8 ㎛ CMOS 파라미터로 HSPICE 시뮬레이션 결과, 20Ms/s에서 100 ㎑의 입력 신호에 대한 SNR은 43 dB로 7-비트의 해상도를 만족하였고 27 ㎽의 소비전력 특성을 나타냈다. In this paper, it is proposed to a new architecture of CMOS IADC(Current-Mode Analog-to-Digital Converter) using 1.5-bit bit cell of which consists a CSH(Current-Mode Sample-and-Hold) and CCMP(Current-Mode Comparator). In order to guarantee the entire linearity of IADC, the CSH is designed to cancel CFT(Clock Feedthrough) whose resolution is to meet at the least 9-bit which is placed in the front-end of each bit cell. In the proposed IADC, digital correction logic is simplified and power consumption is reduced because bit cell of each stage needs two latch CCMP. Also, it is available for a mixed-mode integrated circuit because all of block is designed with only MOS transistor. With the HYUNDAI 0.8㎛ CMOS parameter, the HSPICE simulation results show that the proposed IADC can be operated at 20Ms/s with SNR of 43 dB with which is satisfied 7-bit resolution for input signal at 100 ㎑, and its power consumption is 27㎽.
