본 연구는 오늘날 특수교육의 가장 핵심적인 방법론인 '통합교육'을 다룬 중앙일간지 뉴스 기사의 변화과정을 분석하였다. 신문자료는 오늘날 빅데이터 시대의 하나의 가치 있는 분석대상으로 부각되고 있다. 또 언론사 뉴스 분석방법론은 관련 학문 연구자의 언어가 아닌 일반 시민들의 인식수준을 확인하는 데 도움을 준다. 본 연구의 결과는 2000년 이후 20년간의 시간대를 10년 단위로 분할하여, '통합교육'의 모습이 어떻게 전파되었는 지를 확인하였다. 본 연구는 분석대상 자료를 기초로 하여, 객관적인 연구방법론을 추가하여 보완해 나갈 것이다.

본 연구는 Zeigler가 제안한 이산 사건 시스템 형식론(DEVS: Discrete Event System Specification)을 이용한 거시적 및 미시적 교통류 시뮬레이션 방법론의 개발을 주 목적으로 한다. 도로 교통망의 모델링 방법은 미시적(microscopic)방법과 거시적(macroscopic)방법으로 분류된다. 이러한 모델링 방법들은 그 목적에 따라 각기 표현되어 제각기 사용되어 왔으나, 시스템 이론적으로 이들은 독립적 모델이 아니며 오히려 이들은 서로 동질적 추상화 관계에 있어서, 통합 모델링 환경의 구축시 미시적 모델들로부터 추상화에 의한 거시적 모델의 자동생성 등 설계상의 효율뿐 아니라 모델간의 일관성을 통한 모델 유효성을 보장할 수 있는 장점이 제공될 수 있다. 따라서, 본 논문에서는 서로 다른 표현 방법(즉, 이산시간 형식론과 이산사건 형식론)간의 통합 표현을 기반으로 양자간의 추상화 관계를 도출하고, 이를 이용한 모델 추상화를 통해 거시적 및 미시적 교통류 시뮬레이션 방법론을 제안한다. 시스템 이론적 접근을 토대로 접근한 통합 교통류 시뮬레이션 환경은 미국 Berkeley 대학 교통 연구소에서 개발한 SHIFT 등과 같은 최첨단 교통류 시뮬레이션 도구에 비하여 SES/MB를 기반을 시스템 이론적이며 소프트웨어공학적인 접근을 통하여, 1) 기존 제어 방식의 검증 및 신뢰도 분석, 2) 각종 사건, 사고의 시간별 파급효과 분석, 3) 도로건설 계획안에 대한 타당성 검토, 4) 운전자 및 관리자를 위한 예측된 교통정보 등을 제공할 수 있을 것으로 기대된다.

Recently, the platforms for open science are being developed for helping researchers and scientists who are interested in convergence studies. This paper is focused on deriving a design method for an integrated architecture for knowledge infrastructure in science and technology and to set up the integration level of details and association between data and services in the integrated architecture. To facilitate the open science in research lifecycle, reconstructing individual services into modular and independent function blocks needs to be reusable and interoperable. The proposed design methodology is used for manipulating a service integration for the convergence service of S&T(Science and Technology) knowledge infrastructure. It can support to seamlessly access computing resources and the research results including artifacts digitally enabled scholars, researchers, and engineers participating in multidisciplinary collaborations.

기술경영의 패러다임은 기업경영을 기술의 가치를 강조하는 쪽으로 급속히 변화 시키고 있다. 기업이 고유한 기술에 대한 관리의 필요성이 대두됨에 따라 기업은 경쟁력을 높이는 한 방안으로 기술의 가지평가에 더 많은 관심을 쏟게 되었다. 기업에 적합한 포트폴리오를 작성하기 위래 선행되어야 할 작업으로써 고유기술에 대한 가치 평가를 시도하고 있는 것이다. 이를 위해서 기업들은 구체적인 기술평가 기반모형이 필요하게 되었으며, 본 연구에서는 다양한 산업 분야에 쉽게 응용될 수 있는 통합적 기술평가 기반 방법론을 제시하고자 한다.

This article analyzes two different strategies that both aim at creating innovative design or problem solving: design thinking and action learning. User-driven innovation strategy that has become more and more popular during the last decades is "design thinking". Based on designerly methods and principles, this strategy was developed by the design consultancy IDEO in the late 90s. Action learning is a pragmatic and moral philosophy based on a deeply humanistic view of human potential that commits us, via experiential learning, to address the intractable problems of organizations and societies. This paper provides a structured analysis and comparison of the two innovation strategies-design thinking and action learning-with the goal to identify potentials to enrich either of the two by merging or adapting specific parts or aspects. Although there are significant differences in both strategies, there are also several similarities in methodology and process design. This article compares process models for action learning and design thinking and highlights the specific differences and similarities. As a result, we suggested a union model of action learning and design thinking, and verified a this model through a case study. We complemented the process of team building and reflection of action learning for union model. Also, we statistically verified through a case study to validate the superiority of the design thinking model which complemented action learning. This article contributes to a better understanding of both-design thinking and action learning, and it may help to improve either of the two strategies to foster social innovation.

Recently, most of global enterprises have geographically distributed organization, thus have distributed information systems which have distributed database systems. So, it is difficult for these systems to provide common views for the application programs of end users. One of solutions to solve these difficulties is an MDBS(Multidatabase System) A method to effectively implement MDBS is a schema integration. This paper proposes a methodology for a schema integration through extraction of common similar subschemas Our methodology is consisted of 5 phases : affinity analysis, extraction of similar subschemas, decision of imtegration order, resolution of semantic conflict, and schema integration. To verify the usability of our methodology, a case study is implemented with an object of MDBS. At a result, our approach can effectively be applied to the extraction of common similar subschemas and schema integration.

A hybrid system is a combination of sub systems which have different types of state and time: a typical example is a combination of discrete event and continuous systems. A HDEVS(Hybrid DEVS) formalism was proposed for modeling and analyzing a hybrid system. The HDEVS formalism allows modelers to construct a hierarchical and modular model based on the mathematical set theory. Because the HDEVS formalism was applied to the distributed and interoperated simulators, modelers should make several heterogenous models dividing a target system. Hence, this paper proposes an extended hybrid coupled model of HDEVS formalism and an integrated hybrid modeling methodology in contrast to the existing simulation framework on interoperable simulators. By applying the proposed modeling method, a target system can be translated to a hybrid model in a similar form as the target system. This paper also contains a simulation engine design for the proposed modeling methodlogy and a case study which simulates water tank control systems.

In this study, we propose a methodology of mating it easy to integrate the heterogeneous and distributed information of e-Business environments with the semantic web components , knowledge representation, ontology and agents. It is based on a collaborative interoperable environment, which should be constructed by meta-modeling and employing agents , and the syntactic/semantic integration. We adopt OWL(Web Ontology Language) to specify ontology in a layered architecture for each agent to use, which is based on the IRDS (Information Resource Dictionary Standard) framework. And we give an illustrative example using the terms from PSL(Process Specification Language)-ontology. By defining, managing and sharing resources and business-processes on the proposed framework, it could be possible to get rid of the cause of redundancy and inconsistency.

This study presents an integrated data mining model for the credit evaluation of the customers of a capital company. Based on customer information and financing processes in capital market, we derived individual models from multi-layered perceptrons(MLP), multivariate discrimination analysis(MDA), and decision tree. Further, the results from the existing models were compared with the results from the integrated model using genetic algorithm. The integrated model presented by this study turned out to be superior to the existing models. This study contributes not only to verifying the existing individual models but also to overcoming the limitations of the existing approaches.
