The ORF5 gene ncodes a major envelopeglycoprotein (GP5), which is one of the thre majorproteins of porcine reproductive and respiratorysyndrome virus (PRRSV). The GP5 protein has benknown to be a 24.5-26kDa N-glycosylated envelopeprotein. The GP5 is involved in inducing neutralizingantibodies. For this reason, the GP5 is primary can-didate for the PRRSV subunit vaccine. To produce thecloned t h e O R F 5 g e n e f r o m P R S V C N V - 1 i n t o t h eSemliki Forest virus (SFV)-based expresion vector,resulting in recombinant pSFV-ORF5. By the infectionwith recombinant pSFV-ORF5 to BHK-21 cells, theGP5 expresion was confirmed by imunocytochemistryand imunobloting asay. The recombinant virusparticle harboring ORF5 gene was infectious to BHK-21and MARC-145. The RNA synthesis and expression ofGP5 in the infected cell was also confirmed byRT-PCR.

During the period from January to December of2001, a total of 3,391 swine sera were submited to urlaboratory from 256 farms for the diagnosis of porcinereproductive and respiratory syndrome (PRS). Theantibody to porcine reproductive and respiratorysyndrome virus (PRRSV) was tested by the indirectimunofluorescent antibody (IFA) test. Of the 256farms tested, 230 farms (89.8%) were positive for thePRRSV antibody was 52.1% (1765/3391). Most of thepigs eemed to be infected with PRSV at around 50to 60 days old. The seroprevalence of the antibodybecame higher with age, and peaked at around 100days old. More than one-third of the adult pigs,including boars, gilts, and sows, was positive for thePRSV antibody. The infection of PRSV was chronicand confined to growers and/or finishers in mostfarms. However, the antibody was detected in alproduction phases at some farms .
State of the Art on ebXML for Port and Logistics Industry

Korean government, port and logistics companies have made a lot of efforts to exchange electronic documents between themselves and their partners. As a result of it, Korean Electronic Data Interchange(EDI) standards were made by the Korean Electronic Data Interchange for Administration, Commerce and Transport(EDIFACT) committee and the standards have been used by companies and governmental organizations in Korea. However, Korean port and logistics EDI system is based on Value Added Network(VAN) and a VAN company has monopolistic right to relay EDI documents to Ministry of Maritime Affairs & Fisheries(MOMAF) and Customs Service. Therefore it leads to a lot of problems such as inconvenient software, expensive transmission fee, insufficient improvement of business process and the difficulty of connection with the in-house systems of user companies. To solve these problems, United Nations Centre for Trade Facilitation and Electronic Business(UN/CEFACT) and Organization for Structured Information Standards(OASIS) are aimed to progress for eXtensible Markup Language(XML) and Internet-based Electronic Business Extensible Markup Language(ebXML) electronic commerce framework. This research is trying to derive an conceptual ebXML model based e-Business for port and logistics industry. Especially, for improving extant problems in the port and logistics industry, this research proposes the Information Strategic Planning(ISP) and Proof of Concept(POC) for ebXML systems.
Enhanced the electrochemical performances of Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode by ZrO2 coating
Sung-Joo Jo,Hyun-SooKim,Do-Yeong Hwang,Bong Soo Jin,Seong-Ju Sim,Jae-Soo Shin,Seung-Hwan Lee 한양대학교 세라믹연구소 2020 Journal of Ceramic Processing Research Vol.21 No.6
ZrO2 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode has enhanced electrochemical performance and stability compared with thepristine. The discharge capacity of both samples have no significant difference. However, the 1.77 wt% ZrO2 coatedLiNi0.8Co0.1Mn0.1O2 material delivers enhanced charge-discharge cycling (capacity retention of 97.1 % after 100 cycles at 0.5C) while the capacity retention of pristine is 94.8 % under the same condition. Based on these, we can infer that the ZrO2coated LiNi0.8Co0.1Mn0.1O2 material shows great cyclability, originated from suppressing undesirable side reaction and decreaseeffectively electrolyte decomposition reaction. Therefore, the ZrO2 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode can beconsidered as an effective strategy for long-life Li-ion batteries.
Calculation of Optical Trapping Forces on Microspheres in the Ray Optics Regime
Kang-BinIm,Dan-YoulLee,Hyun-IkKim,Cha-HwanOh,Seok-HoSong,Pill-SooKim,Byong-ChonPark 한국물리학회 2002 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.40 No.5
The optical trapping forces on a microsphere were calculated by using the ray optics model. The wrong symmetry or mirror image in the ray optics model was corrected to calculate more precisely the optical trapping forces on a dielectric microsphere in a focused laser beam. We compared the optical trapping forces calculated by using the corrected symmetry with those calculated by using the existing models and with the experimental results. The forces calculated by using the corrected symmetry were in better agreement with the experimental results than those calculated by using existing models.e80
