The role of dialogue manager is to select proper actions based on observed environment and inferred user intention. This paper presents stochastic model for dialogue manager based on Markov decision process. To build a mixed initiative dialogue manager, we used accumulated user utterance, previous act of dialogue manager, and domain dependent knowledge as the input to the MDP. We also used dialogue corpus to train the automatically optimized policy of MDP with reinforcement learning algorithm. The states which have unique and intuitive actions were removed from the design of MDP by using the domain knowledge. The design of dialogue manager included the usage of natural language understanding and response generator to build short message based remote control of home networked appliances.

Fuzzy control has been researched for application of industrial processes which have no accurate mathematical model and could not controlled by conventional methods because of a lack of quantitative input-output data. Intelligent control approach based on fuzzy logic could directly reflex human thinking and natural language to controller comparing with conventional methods. In this paper, fuzzy controller is implemented to acquire operator's knowledge. The tested system is constructed for sending a ball to the goal position using wind from two DC motors in the path. This system contains non-linearity and uncertainty because of the characteristic of aerodynamics inside the path. Ball position is measured by a vision camera. The system used in this experiment could be hardly modeled by mathematic methods and could not be easily controlled by linear control manners. The controller, in this paper is designed based on the input-output data and experimental knowledge obtained by trials.

This paper discusses the design, implementation, and potential use of an ontology-based mobile pediatric consultation and monitoring system, which is a smart healthcare expert system for pediatric patients. The proposed system provides remote consultation and monitoring of pediatric patients during their illness at places distant from medical service areas. The system not only shares instant medical data with a pediatrician but also examines the data as a smart medical assistant to detect any emergency situation. In addition, it uses an inference engine to infer instant suggestions for performing certain initial medical treatment steps when necessary. The applied methodologies and main technical contributions have three aspects: (a) pediatric consultation and monitoring ontology, (b) semantic Web rule knowledge base, and (c) inference engine. Two case studies with real pediatric patients are provided and discussed. The reported results of the applied case studies are promising, and they demonstrate the applicability, effectiveness, and efficiency of the proposed approach.

Design of civil infrastructures is generally based on 2-D drawings and analyses. Design provisions also specify the limit states using member based equations. Most construction projects are done through collaboration of engineers who have different specialized knowledge. Information technologies can dramatically enhance the performance of the collaboration. For the information transfer, we need a mediator between engineers. Object based 3-D models are useful for the communication and for the owners who have to maintain whole the information of infrastructures. In this paper, basic guidelines for the 3-D design according to design phases. Adequate interoperability of 3-D objects from any CAD system is essential for the collaboration. Owners, contractors and design consultants were considered as users of 3-D objects. Cost and performance of each design phases was investigated through the existing data.

Managing and reusing knowledge in engineering and construction sectors can lead to greater competitive advantage, improved designs, and more effective management of constructed facilities. The use of Information Technology (IT) in design and construction can exploit strategic opportunities for new ways of integration, sharing and facilitating information and knowledge in any field of engineering. The integrating of separate areas of IT can be used to bring a group of experts and specialists in any field of engineering closer together by allowing them to communicate and exchange information and expertise that facilitate knowledge capture, sharing, and reuse. A lack of an advisory management system and a need to marshal all available data in a common format has indicated the need for an integrated engineering computing environment to investigate concrete repair problems. The research described in this paper is based upon an evaluation management system (EMS) which comprising a database management system (REPCON) alongside visualisation technologies and evaluation system (ECON) is developed to produce an innovative platform which will facilitate and encourage the development of knowledge in educational, evolution and evaluation modes of concrete repair. This allows us to create assessment procedures that will allow the current condition of the concrete structure and its components to be expressed numerically using a confidence level (CL) so as to take the best course of action in the repair and maintenance management. The explained rating system, which is related to structural integrity and serviceability of the structure, allows the confidence level to be determined by visual inspection and the descriptive information and pictures taken from an available REPair of CONcrete (REPCON) database.

본 논문은 시맨틱 검색 시스템에 관한 포괄적인 개념적 모델 제안과 실질적인 구현 사례를 제시한다. 제안된 시맨틱 검색 시스템은 개념적으로 3계층의 아키텍처 지식획득 계층, 지식표현 계층, 지식이용 계층으로 구성하여 설계 및 구현되었다. 지식획득(Knowledge acquisition) 계층은 다양한 소스(Source)의 콘텐츠(텍스트, 이미지, 멀티미디어등)로부터 시맨틱 메타데이터를 생성 및 저장하는 영역이다. 지식표현(Knowledge Representation) 계층은 온톨로지의 스키마와 인스턴스를 구축하고, 이러한 온톨로지 기반 질의 확장 등을 통해 시맨틱 검색을 처리하는 영역이다. 마지막으로 지식이용(Knowledge Utilization) 계층은 검색 이용자가 시맨틱 웹 언어 또는 온톨로지에 대한 지식이 없더라도 직관적으로 검색 질의(Query)를 입력하고 검색 결과를 확인할 수 있도록 구성하였다. 향후 제시된 시맨틱 검색 시스템은 기존 연구 수준의 시맨틱 검색 시스템을 상용화 수준으로 향상시킬 수 있는 계기가 될 것으로 기대된다.

The Purpose of this study was to find out the effects of education for prevention of sexual abuse (rape, sexual assault, sexual harassment etc.) of children in kindergarten teachers. Incidences of sexual abuse in Korea is ranked 3rd in the world. Sexual abuse of children, particularly, is one of the most serious crimes that affect both the victimized children and their family. The issue related to sexual abuse of children has been ignored, and there is a lack of systematic education to prevent sexual abuse of children either for children or their parents in Korea. Furthermore, lack of knowledge and poor attitude of teachers limit their capability to provide education for sexual abuse prevention to the children. The education for kindergarten teachers may change their knowledge of the sexual abuse and their attitude toward it and improve their capability in helping children. 114 Korean kindergarten teachers participated in this study. Research design was one group pretest-posttest design. The education given to the subjects included 2 hours of lecture. The education program was developed based on a survey. Preschool-aged-children, parents, and teachers were interviewed to reveal their educational needs based on their experiences related to sexual abuse. This program includes such as safety education, crisis management, resource person(s), and phone numbers of available hospital. Data was collected before and after the education was given to the subjects, to assess their knowledge and attitude toward child sexual abuse. Two instruments were used in this study. Using Cronbach's ALPHA validity and reliability of 2 instruments were tested. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics, t-test and ANOVA. The results of this analysis were as follows : 1. After education, the score of kindergarten teachers knowledge was higher than before (t=-4.409, p=0.002). 2. After education, the score of kindergarten teachers attitude was higher than before (t=3.065, p=0.003). The findings from this study will provide an intervention strategy for prevention of sexual abuse in children.
