Polyacrylonitrile(PAN)/polyacrylamide(PAAm) and PAN/copolymer(poly(AAm-co-AN)) blend fibers were prepared by solution spinning using nitric acid as a solvent. and stretched to 3, 5 and 7 of draw ratio. The effects of blend ratio and draw ratio on the viscoelastic and shrinking behavior of the fibers were investigated. The peak position of tan § related to Tg of PAH/copolymer fiber shifred towards higher temperature as the content of AN in AAm/AN composition of the copolymer is increased, while the tan 6-peak position of PAn/PAAm fiber has the same as that of pure PAN. The tan 6-peak temperature of PAN/topolymer fiber shifted to lower temperature with increasing draw ratio. The shrinkage of pure PAU, PAM/PAAm and PAN/copolymer fibers increased with increasing heat treating temperature and AN content in copolymers. but decreased with the increment of the draw ratio. It was concluded that the miscibility of the copolymer with PAN is better than that of PAAm and increased with increasing AW content of copolymer.

The correct and opportune decision of reengaging the intercepted target is required in order to enhance the engagement performance of the surface to air missile systems that has the ability to defense or attack against various targets at the same time. The engagement efficiency and success of these systems will be largely enhanced by assigning quickly its system resources to the intercepted target and minimizing the waste of system resources for the target which is not able to attack any more. The kill-assessment algorithm has to be able to evaluate automatically whether various targets intercepted by missiles are killed or not on the basis of the reasonable confidence level. The definition of kill assessment is discussed and the kill assessment algorithm is designed reliably by using Kalman filter and a probability theory. Finally its performance is evaluated and analyzed by the Monte Carlo simulation.

Weapon systems composed of several subsystems execute various engagement missions in distributed combat environments in cooperation with a large number of subordinate/adjacent weapon systems as well as higher echelons through tactical data links. Such distributed weapon systems require distributed real-time simulation test beds to integrate and test their operational software, analyze their performance and effects of cooperated engagement, and validate their requirement specifications. These demands present significant challenges in terms of real-time constraints, time synchronization, complexity and development cost of an engagement simulation test bed, thus necessitate the use of high-performance distributed real-time simulation architectures, and modeling and simulation techniques. In this paper, in order to meet these demands, we presented a distributed real-time simulation system based on High Level Architecture(HLA) and Discrete Event System Specification(DEVS). We validated its performance by using it as a test bed for developing the Engagement Control System(ECS) of a surface-to-air missile system. The proposed technique can be employed to design a prototype or model of engagement-level distributed real-time simulation systems.

This paper describes a method of building Korean conversational speech data in the emergency medical domain and proposes an annotation method for the collected data in order to improve speech recognition performance. To suggest future research directions, baseline speech recognition experiments were conducted by using partial data that were collected and annotated. All voices were recorded at 16-bit resolution at 16 kHz sampling rate. A total of 166 conversations were collected, amounting to 8 hours and 35 minutes. Various information was manually transcribed such as orthography, pronunciation, dialect, noise, and medical information using Praat. Baseline speech recognition experiments were used to depict problems related to speech recognition in the emergency medical domain. The Korean conversational speech data presented in this paper are first-stage data in the emergency medical domain and are expected to be used as training data for developing conversational systems for emergency medical applications.

Mucinous cystic neoplasms of the pancreas are rare primary tumors. They are low-grade tumors that occur predominantly in middle-aged woman. They usually arise within the tail of the pancreas and manifest as large, multiloculated cystic masses. In most cases, they are confined to the tail or body of the pancreas. All mucinous cystic neoplasms should be considered as mucinous cystadenocarcinomas of low-grade malignant potential. Complete surgical excision alone results in an excellent clinical outcome. We experienced a case of mucinous cystadenocarcinoma of the pancreas with invasion to the spleen in a 66-year-old woman. The mucinous cystadenocarcinoma involving the spleen is extremely rare and there has been no case report in Korea. Distal pancreatectomy and splenectomy was performed. It was concluded that multiloculated cyst developed from pancreatic tail and manifested as a huge splenic cyst. We report this rare case with a review of literature.(Korean J Gastroenterol 2001;38:453-456)

지방자치단체에 대한 국가의 감독과 통제

Administration of local governments can be approved within the scope of a national legal system. Therefore, a violation of the national legal system by a local government has to be controlled under the supervision of the central government. The supervision or control of the central government are required for many reasons. For example, it is needed to make up for the weak points in current internal audit systems of local governments. The issue of this paper is related to the two points, the target and the limit of the supervision or control of the central government. Firstly, there is one question on the possibility of the central government's control to an administration of a local government pursuant to the purpose of laws without any specific provision. The Local Autonomy Act provided that the central government and local governments basically associate on an equal footing. It also provides that the Minister of Public Administration and Security, Provincial Governors and Metropolitan City Mayors may audit, revoke or suspend the autonomous affairs in cases where a local government violates any provisions of laws. In practice, however, the central government sometimes tries to involve in administrations of local governments without the considerations of the violations. Therefore, the target of the supervision must be specified by the provisions of laws. Secondly, there is another issue of this paper on the right and the limit of the supervision to local governments. Even if the central government may have the rights, the requirements should be limited to the minimum scope. The limitation can be made by the provisions of the related laws. Furthermore, it is needed to make sure a principle regarding the limitations. For example, the supervision or control of the central government should be done after the self-inspection of local governments.

지방자치와 한국헌법의 과제

Constitutional provisions on the local autonomy could be said as being operated as basic principles of constitution exceeding guarantee effects of prohibiting the local autonomy’s abolition passively when considering about the autonomy’s functions of democracy and division of powers having been executed in modern democratic nations. Thus, centralized national structures are getting from requests of having to be conversed into decentralized ones in the paradigm. Article 117 and 118 contents of current constitution was decided through constitutional revisions in December 26, 1962 when was much earlier than real executions of the local autonomy system, and it is difficult to see it as reflecting the recognition like national structure’s principles in constitutional dimensions based on power’s divisions. So, constitutional revisions for strengthening the local autonomy have become current political issues nowadays. If arranging tasks of our constitution for strengthening the local autonomy centering on discussions of constitutional amendments having been processed at now. it is same as followings. First, it is required to regulate the local autonomy and ideology of power’s divisions to the preamble of constitution, and general provisions so as to declare a fact that the local autonomy is being operated as constitutional principles by exceeding passive guarantees institutionally. Second, though there are assertions such like kinds and hierarchical structures of the local autonomous entity have to be specified to constitution, but prudent reviews on it are necessary. It could be proper same as current situations in that there are questions whether it is related to constitutional matters, and necessary cases of merger and abolitions at the local autonomous entity could be occurred. Third, principles of full power, own sense of responsibility, and supplement that are key contents of institutional guarantees to the local autonomy shall be specified in constitution. The reason is that it is required from respects of suggesting such legislating standards from constitution such like which cases can be regulated to national affairs instead of the local autonomous entity when lawmakers indicate specific affairs. As organ mandate affairs shall be abolished because it is contrary to the ideology of local autonomy, and alternative means have to be devised. Fourth, in order to ensure effectiveness of autonomous laws, ‘within laws and ordinances’in current constitution and local autonomy laws has to be revised to ‘within laws,’ and it is required to enable matters on residents right’s limitation and obligatory to be decided by ordinances by deleting Article 22 proviso at local autonomy laws. Fifth, it is admirable to endow tax legislating rights to the local autonomous entities through constitutional revisions in order to do successful completion of the local autonomy. Merely, careful considerations are necessary from respects that such constitutional revisions could cause great changes in tax system and national financial system wholly. Sixth, in order to guarantee autonomy of local autonomous entities, national audit has to be unified, and purpose-fitting controls on autonomous from audit the Board of Audit and Inspection shall not be permitted. In case of administrative appeals, examining and adjudicating on injustice of autonomous affairs are contrary to protecting spirits of autonomous rights, and thus administrative appeals act has to be revised to the direction of not allowing it. Seventh, participations of local autonomous entities to national administration are necessary for maintaining mutual cooperative relations between nation and local autonomous entities. Merely, careful reviews are needed in introducing the senate system in which local autonomous entities are composed of local representatives because it changes parliament’s configurations basically, and a right to introduce a bill to the house from local government councils in that total national representation to the councils is difficult to be accepted. In relation with deliberating laws to which interests of local autonomous entities are hanged, institutional devises such as notification to the relevant autonomous entity, opportunity endowment of suggesting opinions, and notices of deliberation’s results etc shall be arranged.
