The purpose of this study is to propose the direction of competence of future designers required in the fourth industrial revolution. Designers have played an intermediary role in connecting technology and human beings. Therefore, in the fourth industrial revolution the capacity required to perform the intermediate role as a designer has also changed. The paradigm of design which changed step by step through the literature survey was studied. In addition, priorities were confirmed by comparing past and future designer competencies through prior research on designer competencies. As a result, we confirmed that the planning competence to solve complex problems and the competence of design management to realize them. Based on this research, we hope to be able to recognize the direction of competence as a designer in the fourth industrial revolution and to be a reference material for the follow - up study.

The purpose of this study is to review systematically the literatures on the research of the elderly speech signal processing based on the domestic gender innovation and to introduce the utility and innovation of the gender analysis methods. From 2000 to present, among the 37 research papers published in the Korean Journal, 25 papers were selected according to the inclusion and exclusion criteria. And gender analysis methods were applied to gender research subject and design. Research results show diversity of research field and high gender recognition of R & D team are needed in research and development of engineering of gender innovation perspective. In addition, government-level regulation and research funding should be systematically applied to gender innovation research processes in the elderly voice signal processing and various gender innovation projects. In the future gender innovation in the elderly speech signal processing can contribute to the creation of a new market by developing a voice recognition system and service that reflects the needs of both men and women.

This study was conducted to test the assessment validity and examine the cut-off scores for driving risk as a part of the Self-report Assessment Forecasting Elderly Driving Risk (SAFE-DR) development project. The 132 senior drivers were categorized as either risky of 58 or safe of 74 drivers through the Drivers 65 Plus. Based on this initial assessment, we analyzed the risk prediction cut-offs. Furthermore, we tested the construct, content, and predictive validity. The cut-off score for the prediction of driving risk was found to be 74.5 points. The positive predictive value was 88.6%, and the negative predictive value was 86.3% about the cut-off score, signifying an excellent level of discrimination. Convergent validity, nomological validity, and content validity were found to be appropriate. Therefore, this study confirms that SAFE-DR is an appropriate assessment that can be used to screen dangerous elderly drivers.

This paper established a new smart factory based on manufacturing data for an introductory company focusing on the personalized cosmetics manufacturing industry. We build on an example of a system that collects, manages, and analyzes documents and data that were previously managed by CGMP-based analog for data-driven use. To this end, we have established a system that can collect all data in real time at the production site by introducing artificial intelligence smart factory platform LINK5 MOS and POP system, collecting PLC data, and introducing monitoring system and pin board. It also aims to create a new business cluster space based on this project.

Novel Engineering(NE) is integrated learning model to figure out problems in a book and solve them with creative engineering process. NE has been performed on offline until now. We have to research blended learning projects for COVID-19 outbreak. In this paper, we are going to explore that blended NE is effective to creative problem solving ability. The results showed that blended NE is highly effective to all of four sub-elements; self conviction & independence, diffusion thinking, critical thinking and motivational element. This means that blended novel engineering class is effective to competence-centered class proposed in 2015 revised curriculum. We hope that the research is spread and settled into our school.

Through the converging concept of 'an actor doctor,' this paper deals with an actor and its double, the emotional care giver. In the first place, actor doctors have appeared in the medical scene as hospice volunteers. But, as a developing project, the concept of 'an actor doctor' leads to a professional emotional specialist who works at hospitals during the day and performing at the stage at night. In our contemporary culture, our emotional life is threatened by various social and environmental stimuli. The role of 'an emotional specialist' in our everyday life and hospitals is very essential to our healthy life. Against the backgrounds of the high emotional intelligence and the systemic training, actors are qualified to embody this social vision. From the perspectives of performance studies and cognitive studies, this paper tries scientific explanations of the role, the function, and the techniques of an actor doctor. By doing so, this paper seeks to build a scientific foundation for an actor doctor as an emotional specialist.

강수의 정확한 시·공간적 추정은 홍수 대응, 가뭄 관리, 수자원 계획 등 수문학적 모델링의 핵심 기술이다. 우주 기술의 발전으로 전지구 강수량 측정 프로젝트(Global Precipitation Measurement, GPM)가 시작됨에 따라 위성의 여러 센서를 이용하여 다양한 고해상도 강수량 자료가 생산되고 있으며, 기후변화로 인한 수재해의 빈도가 증가함에 따라 준실시간(Near-Real-Time) 위성 강수 자료의 활용성 및 중요성이 높아지고 있다. 하지만 준실시간 위성 강수 자료의 경우 빠른 지연시간(latency) 확보를 위해 관측 이후 최소한의 보정을 거쳐 제공되므로 상대적으로 강수 추정치의 불확실성이 높다. 이에 따라 본 연구에서는 앙상블 머신러닝 기반 수집된 위성 강수 자료들을 관측 자료와 병합하여 보정된 준실시간 강수량 자료를 생성하고자 한다. 모형의 입력에는 시단위 3가지 준실시간 위성 강수 자료(GSMaP_NRT, IMERG_Early, PERSIANN_CCS)와 방재기상관측 (AWS)의 온도, 습도, 강수량 지점 자료를 활용하였다. 지점 강수 자료의 경우 결측치를 고려하여 475개 관측소를 선정하였으며, 공간성을 고려한 랜덤 샘플링으로 375개소(약 80%)는 훈련 자료, 나머지 100개소(약 20%)는 검증 자료로 분리하였다. 모형의 정량적 평가 지표로는 KGE, MAE, RMSE이 사용되었으며, 정성적 평가 지표로 강수 분할표에 따라 POD, SR, BS 그리고 CSI를 사용하였다. 머신러닝 모형은 개별 원시 위성 강수 자료 및 IDW 기법보다 높은 정확도로 강수량을 추정하였으며 공간적으로 안정적인 결과를 나타내었다. 다만, 최대 강수량에서는 다소 과소추정되므로 이는 강수와 관련된 입력 변수의 개수 업데이트로 해결할 수 있을 것으로 판단된다. 따라서 불확실성이 높은 개별 준실시간 위성 자료들을 관측 자료와 병합하여 보정된 최적 강수 자료를 생성하는 머신러닝 기법은 돌발성 수재해에 실시간으로 대응 가능하며 홍수 예보에 신뢰도 높은 정량적인 강수량 추정치를 제공할 수 있다.

Recently, a combination of Business Process Management (BPM) and Service Oriented Architecture (SOA) is being recommended as the best approach for automating large business systems. And the need to create meaningful information from daily operational data is increased today. In this paper, we propose a methodology for automating business processes based on the BPM-SOA convergence trend and verify the methodology by implementing the project management business process. BPM-SOA convergence provides higher extensibility and productivity due to the loosely coupled system construction and maintenance. The system has good properties for frequent process changes and reuse of duplicate processes. We then analyze extensibility of the system as new business processes are added to the existing system. We finally analyze the data generated by BPM by using SAP business intelligence to support management's decision making and strategy. Business intelligence provides not only useful data for business decisions but also chance to optimize the business processes.

현재 국내에서 웹을 기반으로 한 e-learning 콘텐츠는 많이 개발되고 있으나 이들 대부분이 매뉴얼 식으로 제작되어 멀티미디어 형식만 빌려 텍스트 형태로만 구성하는 방식이 주를 이루고 있는 실정이다. 따라서 본 논문에서는 SMIL을 기반으로하여 멀티미디어 아날로그와 디지털 자료를 융합할 수 있는 핵심 기술을 제안하며, 이를 웹 상에서 창의적이고, 자기주도적으로 개인차에 따라 학습 속도를 조절할 수 있는 프로젝트 학습기법을 국내 교육환경에 맞게 교수-학습 이론을 적용하여 설계 구현하였다.

In the past several years there has been increasing the studies using ubiquitous technology as the base technology of IT-convergence. The cooltown, one of the ubiquitous projects, is based on the web technology and the mobile environment. However, in the cooltown system, users only get a pre-made web-page. In this paper, we propose the algorithm improved usability applying the context-awareness based on the sensor network. In this paper, we can provide a custom tailored service overlooked in the existing system from this.
