This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

Pronouns are frequently dropped in Korean sentences, especially in text messages in the mobile phone environment. Restoring dropped pronouns can be a beneficial preprocessing task for machine translation, information extraction, spoken dialog systems, and many other applications. In this work, we address the problem of dropped pronoun recovery by resolving two simultaneous subtasks: detecting zero-pronoun sentences and determining the type of dropped pronouns. The problems are statistically modeled by encoding the sentence and classifying types of dropped pronouns using a recurrent neural network (RNN) architecture. Various RNN-based encoding architectures were investigated, and the stacked RNN was shown to be the best model for Korean zero-pronoun recovery. The proposed method does not require any manual features to be implemented; nevertheless, it shows good performance.

대화 시스템(dialogue system)은 텍스트나 음성을 통해 다양한 분야에서 특정한 목적을 수행할 수 있는 시스템이다. 대화 시스템을 구현하기 위한 방법으로 인공 신경망(neural network)을 기반으로한 end-to-end learning 방식이 제안되었다. End-to-end learning 방식을 이용한 식당 예약 시스템 모델의 학습을 위해 페이스북은 영어로 이루어진 식당 예약에 관련된 학습 대화 데이터셋(The 6 dialog bAbI tasks)을 구축하였다. 하지만 end-to-end learning 방식의 학습은 많은 학습 데이터가 필요하다는 단점이 존재하는데, 액션 템플릿(action template)의 정의를 통해 도메인 지식을 표현함으로써 일반적인 end-to-end learning 방식보다 적은 학습량으로 좋은 성능의 모델을 학습할 수 있는 Hybrid Code Network 구조를 제안한 연구가 있다. 본 논문에서는 Hybrid Code Network 구조를 이용하여 한국어 식당 예약 시스템을 구축할 수 있는 방법을 제안하고, 한국어로 이루어진 식당 예약에 관련한 학습 대화 데이터를 구축하는 방법을 제안한다.

Subjects included Hyomin Kim and Eunha Sohn (fictitious names) of Purum Class (a class for 5-year-olds) at 'H' Kindergarten. Subjects were selected after interviews with teachers and observation by the researcher. This study examined communication with classmates focusing on spontaneous dialog situations and functions. Results showed that Hyomin and Eunha exercised power in the art group and the math groups, respectively. The power exercise processes comprised a variety of behaviors including : to become similar with each other; to assign an exclusive seat; to act as an elder sister; to allow to do something; to keep a friend ata distance; to defend oneself; to threaten or persuade with a diversity of linguistic strategies; to teach like a teacher.

화행이란 의사소통 과정에서 발화자가 가지는 발화 의도를 말한다. 성공적인 의사소통을 위해서는 발화자의 화행을 정확하게 파악하는 것이 매우 중요하다. 본 논문에서는 한국어 대화체 문장의 화행 자동분류를 위해, 화행을 결정짓는 요인이 무엇인지 언어학적으로 분석하고자 하였다. 한국어 수업 대화를 분석하여 화행 분류 체계를 새롭게 자체 정립하였고, 언어학적 근거를 바탕으로 10개의 화행 분류 자질을 제안하였다. 또한 제안하는 화행 분류 자질을 검증하고자 웨카(Weka)를 이용하여 정확률 실험을 진행하였다.

Design of drawing dies used in real industrial environments. It was designed by CAD software in many small & medium companies, but many products require various types, and sizes. Therefore, many companies are required to reduce process time and design mistakes. In this paper, for the automatic design of drawing dies, Design process considered that easy to team and use. which are used with Visual LISP/DCL language in a commercial CAD package, AutoCAD. It has adopted GUI in design system, and has applied DCL language. The system is based on the knowledge base system which is involved a lot of expert's know-how We have built database of design type and detail sizes. The automatic design system requires basic product type and sizes. Then the system accesses to the database and find out sizes by comparing with input parameters and generate drawing dies file.

Simulation is one of the most widely used techniques in operations research and management science, but there are several impediments to even wider acceptance and use of simulation. One of the more significant limitations is the dependence of simulation on statistical methodology. This research identifies eighteen different statistical issues in simulation methodology and develops an expert system which could through interactive dialog with simulation analysts offer advice on statistical approaches which might be used to deal with particular issues and to accomplish required statistical computations. This research revises the previous study published in Simulation by incorporating additional statistical issues in the expert system to enhance its performance in analyzing a given simulation problem with statistical methodologies. An overview of the revised system is given and illustrations of the capabilities of the system are presented.

The pre-processor for finite to element structural analysis considering the user-friendly device is developed by using GUI. This can be used on WINDOWS' environment which is realized the multi-tasking and the concurrency by object-oriented paradigm. Data input can be done easily through menu, dialog box, automatic stepwise input and concurrent representation with the structural geometry on multiple windows. It in designed to control integratedly the pre-processing, execution and the post-processing of the finite element structural analysis program on multiple windows, and input data can be seen with result outputs at the same time. In addition, the object-oriented programming environment makes convenient revision and addition of the program components for expanding the scope of analysis and making better user environment.

언어는 단순히 인간의 의사소통의 수단이 될 뿐만 아니라 사고, 추론, 판단 등의 지적활동의 도구로서 활용된다. 컴퓨터에서는 인간의 언어를 사용하여 인간과 유사한 지적활동을 실현하고 자 하는 연구로 일상언어 컴퓨팅(everyday language computing)이 있다. 본 논문에서는 일상언어 컴퓨팅을 실현하는 한 예로 교통정보 서비스를 위한 대화시스템을 제안한다. 제안하는 시스템은 시스테믹 기능문법(Systemic Functional Grammar: SFG)을 기반으로 사용자의 발화를 3개의 메타기능을 통하여 의미를 분석하고, 메타기능으로 표현된 의미로부터 시스템의 발화를 생성한다 기존 교통정보 서비스는 DB의 질의검색과 일률적인 정보제공이 일반적인 것에 비해, 제안하는 대화시스템은 대화의 의미 속에 포함된 사용자의 의도 및 의미를 분석함으로써 보다 적절한 정보를 제공하여 사용자의 서비스만족도를 향상 시키는 교통정보서비스를 가능하게 한다. 또한, 웹과 연동되는 VXML(Voice Extend Makeup Language)을 대화시스템에 적용함으로서 실용적인 인터페이스를 실행하였다.

In this paper, we propose a method how to determine the medical section select that get input the conditions of illness from a dialog-box using a fuzzy logic as a guidance system of the Cyber Hospital. It is to offer an output the most matched section for medical treatment using the Algebraic product fuzzy inference and Max inference after match the membership degree table of symptoms of received input from patient and their information. It will present of the direction for ignored patient which of a medical section select.
