This research suggests a design process that effectively complements the human-centered design through an objective data-driven approach. The subjective human-centered design process can often lack objectivity and can be supplemented by the data-driven approaches to effectively discover hidden user needs. This research combines the data mining analysis with co-design process and verifies its applicability through the case study on the smart heating jacket. In the data mining process, the clustering can group the users which is the basis for selecting the target groups and the decision tree analysis primarily identifies the important user perception attributes and values. The broad point of view based on the data analysis is modified through the co-design process which is the deeper human-centered design process by using the developed workbook. In the co-design process, the journey maps, needs and pain points, ideas, values for the target user groups are identified and finalized. They can become the basis for starting new product development.

Process mining has generally analyzed the default logs of Information Systems such as SAP ERP, but as the use of automation software called RPA expands, the logs by RPA bots can be utilized. In this study, the actual status of RPA automation in the field was identified by applying RPA bots to the work of three domestic manufacturing companies (cosmetic field) and analyzing them after leaving logs. Using Uipath and Python, we implemented RPA bots and wrote logs. We used Disco, a software dedicated to process mining to analyze the bot logs. As a result of log analysis in two aspects of bot utilization and performance through process mining, improvement requirements were found. In particular, we found that there was a point of improvement in all cases in that the utilization of the bot and errors or exceptions were found in many cases of process. Our approach is very scientific and empirical in that it analyzes the automation status and performance of bots using data rather than existing qualitative methods such as surveys or interviews. Furthermore, our study will be a meaningful basic step for bot behavior optimization, and can be seen as the foundation for ultimately performing process management.

In cloud environment, enterprises use a number of systems which are not interconnected and save master information in a distributed way in each of them. Master information which is not managed is incorrect and discord each other so that lowers efficiency of business process and disables optimum decision making. It is necessary to do high-qualified management of master information to operate efficient and errorless business process. This paper suggests TMDM as a solution to solve heterogeneous problems occurred between interconnected master information in cloud environment and to manage business process in an efficient method. TMDM is an information storage that is suggested to solve mutual discord problems between master information using Topic Maps that considers correlation between data. Topic Maps can be connected by association between topics in order to access through a topic to all related knowledge information which is described by the topic. This also can be applied to master information between legacy systems within cloud.

The role of local decentralization and balanced regional development becomes important due to the concentration of population due to urbanization, and the development of tourism contents in local governments is actively being attempted. However, this is largely due to quantitative growth, and it does not offer tourist content that offers a different experience while utilizing regional characteristics. This means that it is important to develop programs and contents that emphasize the identity of the region by cultivating local characteristics and build a different image. However, most of the small regions where characteristic resources are difficult to find have a problem that it is difficult to develop different programs and contents due to relatively few development opportunities and financial constraints. In this study, it was considered that it is effective to analyze characteristic features of the region and utilize the possessed assets as much as possible. Therefore, we propose a service design process that effectively supports ecotourism, one of the regional revitalization plan using local eco - assets. In the process, Venn Diagram Position and Context Map methodology was developed and verified through Sutonggol Observation Path.

Smart-textronics technology which enables functional textiles has recently been applied in various fields such as smart clothes, smart home and smart health care, and a variety of smart-textronics products have been developed. In this context, the smart-textronics product development process is proposed based on the systematic participatory design method in this paper. The proposed method consists of two phases: in-depth interviews and analyzing. In the phase of in-depth interviews, participants are asked to create journey maps that include activities, pain points and emotional status and to generate solution ideas with sketches and simple prototypes. In the analyzing phase, design researchers investigate the participants' journey maps, and create personas by identifying critical characteristics with the behavior pattern analysis. Then, each persona's needs are linked with value elements of the E3 value framework. Finally, pre-survey was conducted to identify smart-textronics market and a smart sofa design is proceeded as the case study to show the applicability of the proposed method.

본 연구에서는 일관제철 공정의 철강산업과 같은 대규모 기계설비 집약적 산업 환경에 적합한 기술지식 경영시스템에 대해 고려하고자 한다. 기술경쟁력 확보를 위한 철강업체의 전략적 기술경영은 핵심기술에 대한 지식경영 활동과 연계될 때 비로소 시너지효과를 극대화할 수 있다. 또한 철강업체의 지식경영은 암묵적 혹은 형식적 제철공정 기술지식의 창출, 획득 및 공유 등의 활동을 통해 활성화되어야 한다. 본 연구에서는 먼저 철강산업 현장의 기술지식 관리대상으로 조업설비 프로세스 및 무형 지식자산의 범위를 정의하고, 일관제철 공정의 핵심기술 로드맵에 따라 기술지식 경영활동에 적합한 계층적 지식경영 조직구조를 구축하고자 한다. 또한 제철공정 노하우 등과 같이 암묵적 기술지식을 획득하고 이를 공유할 수 있는 형태로 변환하기 위한 기술지식 획득 방법론을 수립하고 이를 기초로 인터넷에 기반을 둔 제철공정 기술지식 경영시스템을 구축하고자 한다.

IMF 이후 연봉제의 도입과 정착과정에서 대부분 기업들이 연봉제의 연착륙과 함께 실질적인 성과창출에 많은 관심을 가지면서 효과적인 성과평가시스템의 구축에 주력하고 있지만 '전사 > 사업부 > 부서(팀) > 개인'으로 이어지는 일련의 목표연계과정과 부서(팀) 수준의 올바른 목표설정측면에서 그 방법론의 이해부족으로 혼란을 겪고 있는 실정이다. 본 연구는 효과적인 성과평가시스템이 작동되기 위한 전제조건인 부서(팀) 수준의 바람직한 목표설정방법 이 무엇인지에 초점을 두고 논의를 진행하였다. 특히 개별 부서(팀)이 궁극적으로 달성하려고 하는 본질적 성과목표인 'Value Added results'(VAR)의 개념에 초점을 맞췄다. 그리고 VAR 관점에 따라 본질적인 부서(팀) 목표를 도출하는 네 가지 방법인 고객다이어그램, 목표할당, 팀 피라미드, 프로세스맵에 대해 살펴본 후 마지막으로 실제 기업에서 이 네 가지 방법에 의해 도출된 VAR의 예를 인용하였다.

최근 SoC 기술이 발달하면서, 내장형 시스템을 위한 프로세서 개발이 활발해졌다. 새로운 프로세서가 개발되면, 운영체제 및 소프트웨어 개발을 위해 컴파일러 및 디버거가 필요하다. 컴파일러는 소스코드를 타겟 프로세서에서 실행 가능한 목적파일로 변환하고, 디버거는 프로그램의 개발에서 오류를 찾기 위한 도구로 소프트웨어 개발에 매우 중요한 도구들이다. 본 논문에서는 KAIST에서 개발하는 32bit 프로세서인 Core-A를 위한 소프트웨어 디버거를 설계 및 구현한다. Core-A용 디버거는 공개 소스 디버거 시스템인 GDB를 참조모델로 했으며, 레지스터와 메모리 맵과 같은 프로세서 종속적인 부분을 확장하고 외부 인터페이스 모듈과 같은 프로세스 독립적인 모듈은 재사용함으로써 개발기간을 단축시켰다. 그리고 Core-A용 디버거의 검증을 위해 상용 디버거 시스템인 ARM용 AXD 디버거와 비교 실험을 진행하였다.

An Enterprise Architecture (EA) Framework is a tool which supports implementation of the Enterprise architecture that is used to enhance the interoperability of the IT components. In this paper, we propose a framework named as ENAE (ENterprise Architecture Framework) which combines enterprise architecture unit (AU), reference model, and association relationship between domain model. Architecture Unit is defined as a minimum set of a business process and its associated components such as application system and technical components. An EA can be designed and implemented by the aggregating the related AUs including association relationship between Architecture Units. Because UML model has limitations to describe business domain semantics because it is designed for general purpose, we adapt the DSM (Domain Specific Modeling) concept. We describe association relationship between Architecture Units designed by Domain Specific Modeling through Topic Map. Session 2 describes related works about Enterprise Architecture frameworks, Domain Specific Modeling, and Topic Map, while Session 3 explains components of the ENAF. Finally Session 4 shows the case study for implementation of the new Framework called ENAF.
