A method to automate hazard analysis of chemical plants is proposed in this paper. The proposed system is composed of three knowledge bases - unit knowledge base, organizational knowledge base and material knowledge base, and three hazard analysis algorithms - deviation, malfunction and accident analysis algorithm. Hazard analysis inference procedure is developed based on the actual hazard analysis procedures and accident development sequence. The proposed algorithm can perform hazard analysis in two methods and represent all conceivable types of accidents using accident analysis algorithm. In addition, it provides intermediate steps in the accident propagation, and enables the analysis result to give a useful information to hazard assessment. The proposed method is successfully demonstrated by being applied to diammonium phosphate manufacturing process. A system to automate hazard analysis is developed by using the suggested method. The developed system is expected to be useful in finding the propagation path of a fault or the cause of a malfunction as it is capable to approach causes of faults and malfunctions simultaneously.

Detection of Individuals Restoring Fertility by DNA Fragment Converted into STS (sequence tagged site) in Red pepper

Lee,Jang-Soo,Lee,Keun-Hyang,Kim,Yeo-Song,Kang,Kwon-Kyoo,Nou,Ill-Sup,Hirata,Yutaka 한국자원식물학회 2004 Plant Resources Vol.7 No.2

Co-segregation of male fertility with DNA markers selected by RAPD analysis as being potentially linked to the restorer gene (Rf) for Cytoplasmic male sterility (CMS) was analyzed using segregating F2 population. One RAPD marker directly linked to the Rf locus was identified. Amplification of OPT-02/570 using the STS primers generated a monomorphic band of each fertile plants randomly selected F2 progenies. From these results, this specific marker would be strongly linked to be restoring gene. The use of STS marker is effective in overcoming the reliability of the RAPD phenotype and improving their utility for MAS, co-dominant STS markers are especially very useful.

Hybrid Breeding of Red Pepper (Capsicum annum L.) Using Cytoplasmic Male Sterile Lines Combined with Phytophythora Resistance in Korea

Lee,Jang-Soo,Kang,Kwon-Kyoo,Hirata,Yutaka,Nou,Ill-Sup,Thanh,Vo-Cong 한국자원식물학회 2004 Plant Resources Vol.7 No.2

We characterized the resistances such as to waterlogging, Phytophythora and viruses in hybrids between Italian and Korean mother lines and screened them for complex resistances and agronomic traits to select elite multi-resistant lines for hybrid breeding. Resistance to waterlogging was selectable due to diversity of the resistance. Phytophythora resistance introduced from Italian lines could also be combined with resistance to other diseases and restoration abilities from cytoplasmic male sterility that has been maintained in Korean varieties.

한국 불교 1600년사에 길이 빛날 업적을 남기고, 동국 불교의 큰 별로 추앙받고 있는 청담 대종사(이순호; 1902-1971)의 유심사상을 고찰해 봄으로서 우리 나라의 현대 인성교육 발전에 시사점을 모색해 보고자 하였다. 그 시사점은 모색해보면 다음과 같다. 첫째, 인간주체로서의 마음을 교육하교 인간이 되는 것은 교육하는 인성교육에 그의 마음의 사상은 새로운 인식을 제공해준다. 둘째, 그의 자아의 확립과 자아발견의 교설이 자아실현을 위한 가치교육에 크게 기여하리라 본다. 셋째. 그의 마음의 사상은 유아기의 인성교육에 기초가 됨을 시사한다. 넷째, 그의 마음사상은 더불어 살기 위한 도덕교육에 시사하는 바가 크다. 다섯째, 남북통일을 대비하고 세계평화를 지향하는 평화교육에도 시사하는 바가 크다. Venerable Chung-dam's mind theory was studied in order to give implications to the development of modern personality education in Korea. Venerable Chung-dam(Soon-ho Lee: 1902-1971) produced outstanding achievements in Korean Buddhism of 1600 years and is winning respect as a great admirer of Korean Buddhism. The implications are as follows. First, his mind theory serves a new recognition to the personality education which teaches the mind as a subjective human and the way of being a human. Second, his Buddhist sermon on the perfection and discovery of self contributes on the value of education for self-realization. Third, his mind theory implicates the basis of personality education in the babyhood. Fourth, there are lots of implications of moral education to share lives in his mind theory. Last, his mind theory has a lot of implications of peace education to prepare the unification of North and South Korea and to intend to the peace of the world.

Xenotransplantation 2010; 17: 224–232. © 2010 John Wiley & Sons A/S.</P><P>Abstract: Background: </P><P>Xenogeneic cellular immune responses are mediated by either direct or indirect pathways depending on the participation of donor or host antigen presenting cells, respectively. The contribution of direct response of human T cells, especially memory T cells, to porcine antigen presenting cells is currently unknown. Here, we sought to determine whether human peripheral blood memory/activated phenotype T cells are directly responsive to porcine endothelial cells.</P><P>Methods: </P><P>Porcine aortic endothelial cells (PAECs) were prepared from Yorkshire or miniature pigs. Highly purified human T cells, including naïve and memory/activated phenotype cells, were incubated with PAECs with or without the addition of exogenous cytokines.

In addition, both populations of xenogeneic human CD4<SUP>+</SUP> T cells exhibited similar and diverse V&bgr; usage.</P><P>Conclusion: </P><P>Due to the considerable contribution of human CD45RO<SUP>+</SUP>CD4<SUP>+</SUP> T cells to the xenoreactivity against PAECs, effective control of xenogeneic memory/activated T-cell responses would significantly affect long-term survival of transplanted grafts.</P>

While <B>1</B> exhibits a phosphorescence band centered at 531 nm, which is red-shifted compared to that of unsubstituted (<I>ppy</I>)<SUB>2</SUB>Ir(acac) (<B>3</B>) (λ<SUB>em</SUB> = 516 nm), the emission spectrum of <B>2</B> shows a blue-shifted band at 503 nm. Comparison with the emission band for the 4-fluoro-substituted <B>4</B> (λ<SUB>em</SUB> = 493 nm) indicates a substantial bathochromic shift in <B>1</B>. Electrochemical and theoretical studies suggest that while carborane substitution on the 4-position of the phenyl ring lowers the <SUP>3</SUP>MLCT energy by a large contribution to lowest unoccupied molecular orbital (LUMO) delocalization, which in turn assigns the lowest triplet state of <B>1</B> as [d<SUB>π</SUB>(Ir)→π*(<I>C</I><SUP>∧</SUP><I>N</I>)] <SUP>3</SUP>MLCT in character, the substitution on the 5-position raises the <SUP>3</SUP>MLCT energy by the effective stabilization of the highest occupied molecular orbital (HOMO) level because of the strong inductive effect of carborane.

371 균주의 해양박테리아를 광양만에서 분리하였다. 우점종은 Pseudomonas aeruginosa, Aeromonas hydrophila, P. fluorescens, P. paucimobilis, Chryseomonas luteola, P. vescularis 등이었다. 영양염과 유기물을 제거할 수 있는 해양박테 리아를 탐색하기 위하여 암모니아성 질소(100 mg/L), 질산성 질소(100 mg/L) 및 인(10 mg/L)이 각각 포함된 10 mL의 marine broth 2216 (DIFCO)에 해양박테리아를 접종(1.0%, v/v)하고 12시간 배양하였다. 스크리닝 테스트 결과 25% 이상 COD을 제거하는 해양박테리아는 16종, 15% 이상의 암모니아 질소를 제거하는 해양박테리아는 9종, 60% 이상의 질산 질소를 제거하는 해양박테리아는 11종 그리고 90% 이상의 인을 제거하는 해양박테리아는 13종이 분리되었다. Aeromonas hydrophila, Chryseomonas indologenes, Pseudomonas diminuta, Vibrio parahaemolyticus 균주가 유기물 및 영양염류 제거 실험을 위해 선정되었다. 회분식 시험을 위해 4종의 해양박테리아를 COD_Cr 250 mg/L, NH₃-N 40 mg/L, NO₃-N 40 mg/L, PO₄^3--P 10 mg/L이 각각 첨가되어 있는 변형 marine broth에 접종하고, 10시간 배양하면서 제거효율을 측정하였다. 371 strains of marine bacteria were isolated from Gwangyang bay in Korea. The dominant species were identified as Pseudomonas aeruginosa, Aeromonas hydrophila, P. fluorescens, P. paucimobilis, Chryseomonas luteola and P. vescularis. To screen marine bacteria capable of removing nutrients and organics, marine bacteria was inoculated in 10 mL of marine broth 2216 (DIFCO) with NH₃^-N (100 mg/L), NO₃^-N (100 mg/L), and PO₄^-P (10 mg/L) with 1.0% (v/v), and incubated for 12 h. Results from the screening test, showed that the removal efficiencies for COD_Cr, ammonia niterogen, nitrate nitrogen, and phosphate were over 25% for 16 strains, 15% for 9 strains, 50% for 63 strains, and 15% for 80 strains, respectively. Aeromonas hydrophila, Chryseomonas indologenes, Pseudomonas diminuta, Vibrio parahaemolyticus were selected for nutrients removal experiments. For the batch test, 4 species of marine bacteria were inoculated in modified marine broth containing with nutrients(COD_Cr 250 mg/L, NH₃^-N 40 mg/L, NO₃^-N 40 mg/L, PO₄^-P 10 mg/L, respectively), incubated for 10 hr and the removal efficiencies were measured.
