The software reliability growth model(SRGM) has been developed in order to estimate such reliability measures as remaining fault number, failure rate and reliability for the developing stage software. Almost of them assumed that the faults detected during testing were evetually removed. Namely, they have studied SRGM based on the assumption that the faults detected during testing were perfectly removed. The fault removing efficiency. however. IS imperfect and it is widely known as so in general. It is very difficult to remove detected fault perfectly because the fault detecting is not easy and new error may be introduced during debugging and correcting. Therefore, the fault detecting efficiency may influence the SRGM or cost of developing software. It is a very useful measure for the developing software. much helpful for the developer to evaluate the debugging efficiency, and, moreover, help to additional workloads necessary. Therefore. it is very important to evaluate the effect of imperfect dubugging in point of SRGM and cost. and may influence the optimal release time and operational budget. I extent and study the generally used reliability and cost models to the imperfect debugging range in this paper.

In this paper, the researcher looked into major issues in the "Act (Draft) on Remedy for Damage from Medical Accident and Medical Dispute Mediation, etc." which was proposed by the Health & Welfare Committee, the National Assembly of the Republic of Korea, and which was pending with the Legislation & Judiciary Committee. Then the researcher pointed out worrisome problems therein and presented suggestion" to improve problematic situations. First of all, the researcher examined the following items which are major points in the aforementioned Act: 1) Establishment of Korea Medical Dispute Mediation and Arbitration Center, 2) Procedures for mediation and arbitration of medical disputes, 3) Establishment of Medical Injury Compensation Association, 4) Introduction of proxy payment for damages, 5) Compensation for no-fault medical accidents, 6) A system concerned with special cases on criminal punishment. Next, the researcher closely reviewed the following possible issues: 1) Limit of arbitrary mediation, 2) Postponement of the system concerned with special case on criminal punishment, 3) Examination of reasons for rejection, 4) Function and role of the Appraisal department, 5) A possibility of being reduced to an evidence collection procedure for lawsuit, 6) A possibility of no-fault compensation rather than injury compensation, 7) Operational issues related proxy payment for damages. Lastly, the researcher presented suggestions on how to improve each problematic issue.

The introduction of GSMP open interface to OBS network can materialize to separate the transport plane and the control plane in OBS network. This makes the implementation of OBS switches simple and provides various flexibility. However, the introduction of open interface will cause the connection setup delay because of the additional processing overhead of open interface protocol. Also, in GSMP based network, the location of network management functions are not defined explicitly and the research result about the OBS network management is almost nothing. This paper proposes a parallel connection setup mechanism using centralized connection control server to minimize connection setup delay in OBS network with GSMP open interface and defines managed objects to support connection, configuration, performance, and fault management for the management of OBS network with GSMP open interface. This paper also proposes a distributed network management model, in which the above managed objects are distributed in a controller and an OBS switch according to network management functions. We verify the possibility of OBS control and network management by implementing network management function using proposed parallel connection setup mechanism and distributed network management model.
