A rule based fuzzy expert system in self-tune PID controllers is presented in this paper. The rule base. the core of the expert system, is extracted from the Wills' tuning map and the author's knowledge about the implicit relations between PID gains and controlled output response. The overall control system consists of the relay feedback scheme and the expert system, where the one is responsible for initial tuning and the other for subsequent tuning. The PID control system with the proposed fuzzy expert system, shows better convergence rate and control performances than those of a Litt in spite of the fact that the two rule bases are extracted from the same maps provided by Wills.

The purpose of this study is to analyze nursing students' proficiency with ST(Systems Thinking) approach concerning asthma patient nursing process. For this study, 20 nursing students created causality cognitive maps which were consisted of the contents of 'asthma nursing care'. The word association and causality cognitive map were used to estimate ability of the ST. As a result, the students failed to understand the nursing process with the ST approach, or alternatively they applied low level ST approach and had a lower understanding of it. The findings of this study suggest that the development of a ST-based nursing educational program in order for nursing students to improve their ST ability as well as knowledge integration for multidisciplinary practice.

The use of the internet to facilitate commerce among companies promises vast benefits. Lots of e-marketplaces are building for several industries such as chemistry, airplane, and automobile industries. This study provides the new B2B EC business model for the shipping industry which concerns relatively massive fixed assets to be fully utilized. To be successful the proposed model gives participants useful information. To do this the expert system is constructed with the hybrid prediction system of neural network (NN) and memory based reasoning (MBR) with self-organizing map (SOM) and knowledge augmentation technique using qualitative reasoning (QR). The expert system supports participants useful information coping with dynamic market environment. with this shipping companies are induced to participate in the proposed e-marketplace and helped for exchanges easily. Also participants would utilize their assets fully through B2B exchanges.

Currently Spatial Data is collected and processed in various methods, and its usability is very high. However, the existing Spatial Data analysis Software usually requires professional knowledge in the collection, refinement, and application of spatial Date, making it difficult to access and apply it. Therefore, this study established a new WebGIS platform with improved accessibility and usability to solve these problems. This platform supports various services such as master map sharing, spatial data generation, automatic coordinate system conversion, WMS issuance, grid generation, and grid analysis. These services increase operational convenience, such as simplifying repetitive tasks and automatically expressing text files. While it is believed that non-experts can easily and conveniently because of them to simplify and express the results. In addition, it is judged to have high accuracy and reliability compared to the analysis results using the existing Open Source-based GIS software.

As the artificial intelligence technology has developed recently, researches on chatbots that provide information and contents desired by users through an interactive interface have become active. Since chatbots require a variety of natural language processing technology and domain knowledge including typos and slang, it is currently limited to develop chatbots that can carry on daily conversations in a general-purpose domain. In this study, we propose an artificial intelligence chatbot that can provide real-time public traffic information and route information. The proposed chatbot has an advantage that it can understand the intention and requirements of the user through the conversation on the messenger platform without map application.

Waterfall 모델에서의 소프트웨어 개발 단계는 사용자로부터 요구 사항을 정의하고, 이것이 다음 단계의 input 이 되어 개발자에 의해 작업이 진행되는 개발 양식을 따른다. 시스템 요구 사항을 정의할 때에, 프로세스 관점에서 사용자 업무를 이해하고, 이 프로세스에서 사용되는 시스템과의 관계를 정의하여 요구 사항으로 함께 정의한다면, 단순한 시스템의 기능을 정의하여 개발하는 것 보다 시스템의 사용 목적을 이해하고 개발하게 됨으로써, 더 만족도 높은 시스템으로 개발할 수 있게 된다. 프로세스 관점에서 이해하고 정의하는 시스템의 요구 사항은 시스템 보수 작업(Maintenance)시에도 시스템의 상황이 현재 업무 프로세스와 어떻게 연계되어 있는지 파악하기 용이하고, 테스트 단계에서도 테스트 조건이나 테스트 시나리오로서도 활용이 가능하다. 새로운 업무를 담당하는 사람에게도 시스템 개발 요구 사항에서 정의된 업무 프로세스 맵(Map)이 관련 업무를 파악할 수 있는 기초 자료로 재 활용 될 수도 있다. 비즈니스 프로세스 리엔지니어링에서 사용하는 비즈니스 프로세스 맵핑(Mapping) 기술을 소프트웨어 개발 방법론에 적용하여, 요구 분석 단계에서 사용하는 분석 도구로서의 응용을 제안하고자 한다.

지식지도는 대량의 정보 속에 숨겨진 특별한 형태와 패턴을 찾아서 그 의미를 파악할 수 있도록 가시적인 형태의 결과를 보여주는 것이다. 기존의 지식지도를 살펴보면, 대부분 빈도수나 평균 증가율과 같은 단순한 정보 분석에 그친다는 것을 알 수 있다. 그러나 사용자에게 보다 고차원적인 정보 분석을 통해 주어진 분석대상에 관한 유용한 지식 전달이 필요하다. 본 논문에서는 2000년부터 2009년까지의 컴퓨터 공학 분야의 학술 논문 데이터베이스를 활용하여 지식지도 구축을 시도한다. 이를 위해 학술논문 데이터베이스를 네트워크의 관점에서 분석한다. 그 결과, 네트워크 내에서 패턴을 발견할 수 있었다. 네트워크에서 이러한 분석방법은 학술 분야의 연구동향 패턴을 이해할 수 있게 한다.

In dialogue with the concepts of State of Emergency and Bare Life developed by Giorgio Agamben (1998), this paper explores the novel La transmigración de los cuerpos (2013) by Yuri Herrera, to see how the author builds a narrative space where the logic of the state of emergency is a detonator of the fictional plot. This analysis underlines how Herrera articulates a poetics of precariousness and violence to draw a map of desolation and despair recognizable through the cardinal points of death, fear, corruption and an agonizing will to survive. In this unnamed universe the characters' bodies are subject to violence from the State and from criminals.

Science mapping is a visual representation of the structure and dynamics of scholarly knowledge. Gas adsorption on catalyst supports is a crucial process in many catalytic reactions. The R package "Bibliometrix" and VosViewer software were employed for science mapping analysis. The results show that the upward trend but fluctuates from year to year for both annual scientific production and average article citations per year. Co-occurrence of the keywords were used to identify the primary fields of study and to map the existing state of research. Trending topics reveal some interesting features that support the growth of research in this field and are associated with emerging disciplines or areas of study that have not been extensively explored.
