Two new species of the lichen genus Placolecis are discovered in China, namely P. kunmingensis An. C. Yin & Li S. Wang and P. sublaevis An. C. Yin & Li S. Wang. The new combination P. loekoesiana (S.Y. Kondr., Farkas, J.J. Woo & Hur) An. C. Yin is proposed. Placolecis kunmingensis is characterized by having simple, spherical or ellipsoid, hyaline spores, and pear-shaped pycnidia; while P. sublaevis can be distinguished by its thallus forming larger aggregations with slightly flattened lobes at the thallus margin, and urn-shaped pycnidia. Descriptions, a phylogenetic tree and a key are provided for all the known Placolecis species in China.

횡하중 분포와 등가단자유도 방법의 영향을 고려한 다경간 교량의 내진성능 평가

To evaluate inelastic seismic responses of multi-span-bridge, the equivalent single-degree-of-freedom (ESDOF) methods and the lateral load distributions are applied to the capacity spectrum spectrum method(CSM). From the pushover analysis results using the four ESDOF methods and the six types lateral load distributions, the ESDOF method more than lateral load distribution is found to have an important influence upon the pushover analysis. The effects of the higher mode on the bridge seismic behaviors are also increased as the number of pier increase. Therefore, it can be concluded that lateral load distributions and ESDOF methods for reflection of higher mode effects should be considered in the seismic analysis of the bridge structural.

VPN 관리를 위한 망관리 구조

송왕철,김장형 濟州大學校 工科大學 産業技術硏究所 1998 尖端技術硏究所論文集 Vol.9 No.1

These days the VPN services are provided on basis of the bandwith contracts rather than through leased lines. They require the network managment capabilities. In this paper, hence, an architecture for the VPN service management is proposed on the basis of the structural considerations using the TMN concept. In addtion, the distributed processing technologies are introduced for implementing the architecture. The management architecture for VPN services may be composed of domains for customers and VPN service providers and public network operator/provider, and the domains can be managed via the TMN X interface. Hence, the architecture is modelled hierarchically. It is based on the structuring rule of partitioning and layering on ITU-T G.803 recommendation. On the architecture, the management operations via the X interface can have been performed efficiently by introducing the X.500 directory service and the ODP Trader.

망관리 명명 방식의 접근 제어 모델로의 확장

In this paper, the access control management function of several system management functions(SMFs) from the X.741 ITU-T recommendation is considered for security network management systems based on the common management information service element(CMISE) of OSI network management and a naming method using the general relationship model(GRM) is intended to extended to an access control model. When a manager is to perform network management operations through a remote agent in a distributed network, all managed objects (MO) in the management information base (MIB) that is managed by the agent must have a globally unique name so that each MO in the MIB is identified by the manager and access control functions for the MOs are carried out. Therefore, an access control model is proposed which extends the relationship used in the global naming scheme and in which each MO inherits access control characteristics from a domain class as a superclass in the inheritance tree of the MIB.

지진하중에 대한 다경간 교량의 비탄성 변위응답 평가

송종걸,남왕현,정영화 江原大學校 産業技術硏究所 2004 産業技術硏究 Vol.24 No.A

To evaluate inelastic seismic reponses of multi-span bridge structures, the capacity spectrum method(CSM) incorporating the equivalent single-degree-of freedom(ESDOF) method is presented. Application of the CSM incorporating the ESDOF method is illustrated by example analysis for symmetric and asymmetric bridge structures. To investigate an accuracy of the CSM, the maximum displacements estimated by the CSM are compared to those by inelastic time history analysis for several artificial earthquakes. The results show that the CSM provided conservative estimates of the maximum displacements for the symmetric and asymmetric bridge structures, and the trend of conservative estimates of the asymmetric bridge structures was significantly larger than that of the symmetric bridge structure.

Design and Implementation of a Security Management System for Secured OSI Directory Services

송왕철,김장형 濟州大學校 産業技術硏究所 1996 산업기술연구소논문집 Vol.7 No.1

In this paper, we have designed and implemented a security management system, which is based on the CMISE services. This system provides two security-related System Management Functions(SMFs) to security management users such as notification of a security event alarm and an audit trail of a security related event. These SMFs are implemented using osimis-4.0, OSI Network Management platform. The target of this security management system is secure X.500 directory services based on the Authentication Framework specified in the recommendation X.509. The security system is implemented using OSISEC and its services are data confidentiality, data integrity and non-repudiation of origin. Based on the OSI network management framework, we implemented a manager system which administers the keys and provides CMISE services, and also some remote agent systems which provide services for the events concerning the security system, while also interacting with MIB. Access Control SMF is being implemented.

횡하중 분배방법을 이용한 교량구조물의 비탄성 변위응답 평가

In order to evaluate seismic performance of multi-degree-of-freedom bridge structure, moderate lateral load distribution methods using the pushover analysis were developed by many researchers. One of important variables to improve an accuracy of pushover analysis is lateral load distribution. In this study, pushover analyses were performed using the five types of lateral load distribution and seismic performances were evaluated by capacity spectrum method (CSM). To verify an accuracy of suggested lateral load distribution, the maximum displacement estimates by the CSM were compared to those by inelastic time history analysis.
