This paper presents a systematic description of exceptional pronunciations for automatic Korean pronunciation generation. An automatic pronunciation generator in Korean is an essential part of a Korean speech recognition system and a TTS (Text-To-Speech) system. It is composed of a set of regular rules and an exceptional pronunciation dictionary. The exceptional pronunciation dictionary is created by extracting the words that have exceptional pronunciations, based on the characteristics of the words of exceptional pronunciation through phonological research and the systematic analysis of the entries of Korean dictionaries. Thus, the method contributes to improve performance of automatic pronunciation generator in Korean as well as the performance of speech recognition system and TTS system in Korean.

A serious problem with traditional 'command & control' spectrum management techniques is that they do not easily accommodate new technologies and new services. This paper describes the necessary principles of flexible-use spectrum rights which may allow a wide variety of spectrum uses in a single general-purpose band. Based on the electrospace description of the radio spectrum, these principles allow general aggregation or division of licensed electrospace regions via secondary markets, providing rules for how regulatory limits change under aggregation or division. These flexible-use principles limit transmitter behaviors that tend to create a more difficult operating environment for receivers, while making receivers responsible for handling any remaining interference. The author shows how flexible-use principles could provide a basis for real-world flexible-use frequency bands.

The fuzzy inference system is a popular computing framework based on the concepts of fuzzy set theory, fuzzy if-then rules, and fuzzy reasoning. The advantage of fuzzy approach over traditional ones lies on the fact that fuzzy system does not require a detail mathematical description of the system while modeling. As modeling method. the Group Method of Data Handling(GMDH) is introduced by A.G. Ivakhnenko GMDH is an analysis technique for identifying nonlinear relationships between system's inputs and output. We study a Novel Neuro-Fuzzy Network (NNFN) in this paper. NNFN is a network resulting from the combination of a fuzzy inference system and polynomial neural network(PNN) (7) which is advanced structure of GMDH. Simulation involve a series of synthetic as well as experimental data used across various neurofuzzy systems.

The realization of the avoidance, decrease and utilization of waste can be made through reduction of resource consumption during product production and use. Beside that it is desirable to regain the resource attached to products and components. The same resources can be much used in product and mater all cycle through their reuse and regeneration In order to improve the use productivity of resource the disassembly make up the substantial prerequisite. In this paper a model describing the disassembly sequence structure is introduced under consideration of the influential facts related to disassembly process planning rules for disassembly sequence planning are derived from that.

SDL has been standardized to specify behavioral aspects of communication systems based on the formal description technique, and it is powerful and user friendly in the sense of supporting human communication and understanding, formal analysis andcomparison of behaviors, alternative implementations and design optimization, and its structural decomposition. However, SDL is not sufficient for an efficient handing of entrire system descriptions because the communication systems are generally very complex, and composed from the various interactions among sub-systems. Also, it is very difficult to explicitly verify dynamic views such as liveness and reachability. it leads the demands on analysis scheme to verify dynamic behaviros of specified systems. This paper presents modeling concepts of Petri Nets from SDL and transformation rules to Numerical Petri Nets to provide efficient technqiques for verification of dynamic behaviors, and proposes the reachability garaph that is able to trace all reachable states of a modeled system and reduce an information loss on the reachability tree.

Gori-I nuclear power plant has been examining the effectiveness and efficiency of the current emergency operation procedures from human factors viewpoint. Previous study showed that some mistakes that the procedures did not comply with the writers' guidelines. Reviewing the current writers' guidelines for emergency operating procedures revealed that they lack of some important human factors rules such as enumeration of switching conditions and detailed action requirements, definite expression for setup points, description for anticipated results, and recommendation for use of present tense, affirmative sentence and active voice. This study suggested a new classification system for the writers' guideline contents supplementing the deficiencies of the current emergency operation procedure text.

The rule bases self organizing controller(SOC) has one of its main advantages in the fact that there is no need to have a mathematical description of the system to be controlled. In this controller, the rules are linguistics statements expressed mathematically through the concepts of fuzzy sets and correspond to the actions a human operator would take when controlling a given process. With this controller, we have performed to sight stabilization system, and we realize that it needs a scale factor tuning. The self tuning controller(STC) uses an instantaneous system fuzzy performance which can give an inspection to the scale factor. Therefore, the STC can compensate the scale factor when it is not adequately tuned. With this trial, we shows that STC can give a good transient characteristics in the nonlinearity which imposed basically in the conventional servo system.

Recently Web Services choreography working group of W3C has published the working draft on WSCDL (Web Services Choreography Description Language) version 1.0 which defines reusable common rules to govern the ordering of exchanged messages between Web Services participants. This paper considers a computing environment where mobile clients are interacting with Web Services providers based on a WSCDL specification. In order to effectively cope with the user and device mobility of such an environment, in this paper we present an ongoing work to develop a framework through which a mobile client can specify its preference on how conversation should take place. The proposed framework provides a flexible means for mobile clients to minimize the number of message exchanges while allowing them to adhere to the required choreography.

The purpose of this paper is to expand Stowell (1993), Stowell (1995), Stowell (1996)'s syntactic analysis of tense in English. Stowell treats Tense as a dyadic predicate of temporal ordering which takes those two time-denoting phrases as its arguments. He further argues that those two morphemes 'resent' and 'past' are polarity-sensitive elements encoding an LF-scope relation with respect to true PAST tense. This paper proposes that English future 'will' should be treated as a true tense and that its future morpheme is an anti-PAST polarity item. It also provides a syntactic interpretation of a peculiar morphological aspect of English that it has no future form of the verb. To this end, Stowell's analysis is incorporated into the Minimalist program of Chomsky(1995). It is proposed that, unlike in other languages like French and Spanish, FUTURE in English is of an affix. This provides an intuitively correct description of why English verbs do not have a future form like other languages. The last but not least point which this paper will discuss is that Ogihara (1995a)'s claim that the referential theory of tensed sentences is inadequate is untenable.
