A workflow procedure has recently become more complicated and large scaled. In this paper, we propose an advanced workflow modeling methodology, called a fragment driven cooperative workflow modeling methodology. which enables several real workflow designers to cooperatively define a workflow model. The methodology is a Bottom-Up approach in terms of integrating a set of fragment ICNs to compose a complete workflow model. Each fragment ICN is defined by each participant in the cooperative modeling session, We also use the ICN based formal description and the ICN based graphical notation as well. Finally, we prove the feasibility of the methodology by implementing a cooperative workflow modeling system.

The purpose of this research is to establish the UX methodology knowledge optimized for small sized companies on the basis of theoretical and practical UX development process models. The 7 UX design process models were analyzed by the outcomes and attributes on each design stage from academic field. Then the interview and observation on 18 domestic companies were conducted to clarify the actual methods in use and the gab from the academic theories. The two different design model were unified as an product lifecycle coupled UX process (PLUS). The 100 theory-industry knowedge combined UX design methodologies were selected and aligned along with 6 design stages of PLUS process. Each method was decomposed as a template format that contains standardized attributes applicable for small companies under consideration of their resources, process and produced items. The result of this research is expected to be applied onto real industry and reduce the risk of small manufacturing companies to escalate the quality of UX in their productions.

Knowledge resources are classified with two groups, the records produced by internal parts of company and general information materials from external organizations. Production, acquisition, storage, retrieval and utilization patterns of two groups became similar due to digitization of knowledge resources. And separated RM and IM should be changed integrated management concept. This paper compares RM and IM based on KM governance strategy and several methods to integrate RM and IM. Especially the selection and identification of knowledge resources, information systems to be integrated and the methods of integration and integrators of public enterprises are presented.

With the development of the big data environment, public institutions also have been providing big data infrastructures. Public data is one of the typical examples, and numerous applications using public data have been provided. One of the cases is related to the employment insurance. All employers have to make contracts for the employment insurance for all employees to protect the rights. However, there are abundant cases where employers avoid to buy insurances. To overcome these challenges, a data-driven approach is needed; however, there are lacks of methodologies to integrate, manage, and analyze the public data. In this paper, we propose a methodology to build a predictive model for identifying whether employers have made the contracts of employment insurance based on public data. The methodology includes collection, integration, pre-processing, analysis of data and generating prediction models based on process mining and data mining techniques. Also, we verify the methodology with case studies.

정보SYSTEM을 구축함에 있어서 많은 시간과 노력이 필요하다. 이에 반해 기대되는 효과는 예측하기 힘들거나 명확하지 않은 경우가 많다. S/W개발자의 약점이 개발에는 능하나 업무자체에는 둔감한 것이다. 이를 보완하기 위한 방법으로 업무를 진행하는 사람이 주가 되어 진행하는 개발방법론으로 CIM기법이 대두되었다. 이 기법을 이용하여 통합 정보SYSTEM을 구축하고 효과분석을 실시하였다.

일반적으로 실무에서 공학적인 상충(Trade-offs)의 문제를 해결하는 가장 대표적인 방법론으로 트리즈(TRIZ)가 있다. 지금까지 트리즈관련 연구에 의하면 공학적 파라미터간의 모순을 해결하는 데는 트리즈의 유용성이 이미 확인되었다고 볼 수 있다. 하지만 제품 설계에 있어 트리즈의 사용 범위를 반드시 공학적인 파라미터간의 모순을 해결하는 데 사용을 국한시킬 필요는 없다. 관점을 달리하여 선행설계 엔지니어가 처음부터 소비자의 요구사항에 대한 컨조인트(Conjoint)단계에서 모순을 푼다면 공학적인 문제로 환언(Reduce)시키거나 분화(Breakdown)시켜 제한조건하에서 지엽적이고 복잡한 모순 문제를 풀지 않아도 될 것이기 때문이다. 본 논문에서는 고객 니즈 중심의 컨조인트와 공학 파라미터 모순 해결의 트리즈의 사고를 자연스럽게 연결하기 위해서 제약이론(TOC)의 갈등해소도(CRD : Conflict Resolution Diagram)를 도입하도록 한다. 갈등해 소도는 목적을 달성하기 위해 전행조건의 갈등요소를 확인한 후 타협안을 찾지 않고 잘못된 가정을 엎을 대책으로서 주입(injection) 제시하여 목표를 달성하는 방법이다 따라서 컨조인트의 고객 니즈 최적화를 달성하기 위해 세부 고객 니즈의 갈등요소를 확인하고 트리즈를 주입시켜 제품 설계 목적을 달성할 수 있게 적용하고자 한다. 본 연구의 목적은 첫째, 제약이론(TOC)의 사고를 바탕으로 트리즈를 이용하여 고객니즈의 모순관계를 해결하는 진보된 컨조인트 방법론을 제시하는 것이다. 이 방법론을 앞으로 Conjoint-TRIZ라 표기하도록 하겠다. 둘째, 본 연구에서 제시한 Conjoint-TRIZ 방법론을 자동차 인테리어 설계의 새로운 접근법으로 적용을 시도하여 그 유용성을 검증한다.

Health impact assessment in the environmental impact assessment is conducted to determine whether to exceed the standard of each single substance and to establish appropriate reduction measures. In some development projects, although all substances in risk assessment meet the standard, exposure concentration is very close to it. However, considering the cumulative exposure of all substances, health effects are likely to occur considerably severer than those of individual substances, so it is necessary to prepare a concrete and improved methodology for integrating evaluation of emissions to identify the health effects actually exposed to receptors of living things. This study established the definition of cumulative risk assessment through overseas advanced cases and domestic and foreign literature reviews, and proposed a methodology for utilizing cumulative risk assessment considering health effects on multiple substances when developing industrial complexes. Applied by the proposed methodology, integrated indicators forfourtypes of hazardous heavy metals (Ni, Cr⁶⁺, Cd, As) emitted from industrial complexes were calculated, and applicability was tested with case of the industrial complex development projects conducted over the last decade (2011-2020).

나날이 빨라지는 기술혁신의 시대에 새로운 경제 성장동력을 확보하기 위해서는 미래 유망기술을 선제적으로 포착하고 연구개발을 통해 해당 기술의 주도권을 확보하는 것이 필수적이다. 이를 위해서는 사회, 시장, 산업, 기술 등 다양한 요소를 고려해 미래에 유망할 것으로 기대되는 기술개발 영역을 발굴하는 체계적이고 합리적인 방법론이 요구된다. 본 연구에서는 ICT 융합기술의 발전 방향성, 인문사회적 미래변화 양상, 기술이 탄생되고 소비되는 산업과 시장의 특성 변화 등을 통합적으로 고려해 미래 유망기술을 분석하고 전망하는 방법론으로써 TCM(Tech-Contour Map)을 제안한다. TCM 방법론을 매력도와 생존력이라는 관점에서 미래기술이 가진 특성을 분석해 향후 기술의 진화양상을 전망한다.
