Due to the regular usage of face masks during the COVID-19 pandemic, many people developed skin issues. As a result, interest in skin care which can be performed independently at home has increased. The purpose of this study is to design a customized home beauty care device to respond to these market trends. In order to do so, the double diamond model was applied in the design thinking process, and the design development process proceeded in the order of discovery, definition, development, and delivery. This study is meaningful in that it focused on the user-centered design development approach by fusing design thinking processes rather than styling-oriented design processes, and suggested new possibilities for design development using information based on the data measured.

In this study, the flow characteristics happening inside water tank due to the configuration of various water tank were analyzed by using a computation fluid dynamics program, ANSYS CFX. This study also examined which model was most efficient at the flow by changing the flow conditions of the inlet and outlet due to the configuration of various tank. Same material was applied to models A, B and C. As the result of flow analysis, it was shown that model B had the best flow and model C had the highest pressure applied to the flow. So, though the water tank has the same material according to the configuration of product, the velocity and pressure of flow become different. Therefore, it is thought to develop the tank good for the fluid flow due to the product configuration through this flow analysis result. On the basis of this study result, the esthetic sense can be shown as the analysis data of flow due to the configuration of fluid tank are grafted onto the real life.

In jewelry industry, the proportion of labor costs is high. Also, the production time and quality of products are highly varied depending on the workers' capabilities. Therefore, there is a demand from the jewelry industry for automation. The ear pin insertion automation system is the robot automatically inserts the ear pins into the silicone mold, and this automated system require accurate and fast hole detection method. In this paper, we propose optimal binarization method and a template matching method that can be applied in the ear pin insertion automation system. Through the performance test, it was shown that the applied method has an accuracy of 98.5% and 0.5 seconds faster processing speed than the Otsu binarization method. So, this automation system can contribute to cost reduction, work time reduction, and productivity improvement.

정보통신기술의 발달로 전자상거래의 증가와 소비자들의 제품에 대한 경험과 지식의 공유가 활발하게 진행됨에 따라 소비자는 제품을 구매하기 위한 자료수집, 활용을 진행하고 있다. 따라서 기업은 다양한 기능들을 반영한 제품이 치열하게 경쟁하고 있는 현 시장에서 우위를 점하고자 소비자 리뷰를 분석하여 소비자의 정확한 소비자의 요구사항을 분석하여 제품기획 프로세스에 반영하고자 텍스트마이닝(Text Mining) 기술과 딥러닝(Deep Learning) 기술을 통한 연구가 이루어지고 있다. 본 논문의 기초자료가 되는 데이터셋은 포털사이트의 구매사이트와 오픈마켓 사이트의 소비자 리뷰를 웹크롤링하고 자연어처리하여 진행한다. 감성분석은 딥러닝기술 중 CNN(Convolutional Neural Network), LSTM(Long Short Term Memory) 조합의 모델을 구현한다. 이는 딥러닝을 이용한 제품기획 프로세스로 소비자 요구사항 반영, 경제적인 측면, 제품기획 시간단축 등 긍정적인 영향을 미칠 것으로 기대한다.

While there is the active integration of various industries, a convergence of the software and knowledge service industries including software used in finance and counseling products is creating the necessity to include software industry utilization sectors aside from covering only software products and service production activities. Furthermore, to cope with the radical environment changes in the software industry when it comes to categorizing mobile and cloud computing areas into a software and classification system, we are at a point where there is a need to establish a directional nature on what should be included. In order to establish an integrated classification of newly introduced technologies, products and services, this paper aims to discover areas not included in the classification standard because of the ecological characteristics of the software. It also wants to differentiate the classification system and identify its incomplete areas such as the lack of connections within the system to ultimately establish such for newly surfacing software fields.

IT관련 제품(데스크톱, 노트북, 스마트폰 등)과 자동차, 선박, 자판기 등 기계(Machine)관련 제품과의 융합이 이뤄지고 있으며 각 장비간의 통합 융합으로 변화됨에 따라 네트워크 시스템과 S/W에 대한 보호가 더욱 어려워지고 있는 상황이다. 이러한 문제는 산업계 내에서 다양한 그룹의 사용자들이 다양한 장비를 사용하므로 더 복잡해지며, 결국에는 수많은 기계장치의 사용자 수준에 따라 다른 수준의 보안이 필요하게 된다. 본 논문에서는 차세대 이동통신의 한분야인 M2M(Mahcine to Machine) 통신에 대한 동향 소개와 M2M의 보안 위협요소 분석을 통한 키관리 기법과 Threshold 암호 기법을 소개한다.

협회는 7월5일 IPTV 서비스의 조속한 도입과 아울러 합리적인 제도 마련을 촉구하는 관련업체의 의견을 담은 건의서를 국회 방송통신특별위원회에 전달했다. 또한 국무조정실 방송통신 융합지원단과 정보통신부 융합전략팀에도 전달했다. 협회는 건의서에서, 이해 관계자들의 소모적인 논쟁이 결과적으로 IPTV 서비스 도입정책 지연과 더불어 관련 산업 활성화를 가로막아 산업계의 첨단기술 및 제품들이 사장될 위기에 있으며 국가적으로도 막대한 손실로 이어질 수 있다며 IPTV 서비스의 조속한 도입을 촉구했다. 특히, 협회는 국가 100년 대계를 생각해 더 이상 소모적인 논쟁을 종식하고 국가 신성장 동력인 IPTV 상용화를 통해 IT강국의 위상을 제고해야 하며, 이를 위해 정부의 신속한 제도마련과 뉴미디어에 걸맞은 규제제도 완화가 병행돼야 한다고 주장했다.

As a rapid rate of social change and competitive, paradigm of industry environment manufacturing products and services is shifted. Engineers design, develop, manufacture the products and services are strongly asked competency of different new creative practices. This means while industrial structure has been shifted from mass production to various allied production and social engineering based production, qualifications of engineers are required to individual creative competency as alternatives. In order to improve the competency, engineer become the creative people have ability to develop the professional knowledge competency and expand the competency to convergence the new product and services with sensing the life and social structure shift, human engineering, psychology, and emotion. For the competency, we develop the training program "improving convergence, creativity through Art." we intend that the program should be composed of creative engineering mechanism combined creative arts mechanism. It has been operated to the engineers for 17 weeks. we will discuss the program result and research direction and utilization in depth.

The purpose of this study is to present the factors that affect business model and product innovation on the enterprise performance of the mobile ecosystem, and to confirm the results of whether they have an effect. To this end, through prior research, business model factors and product innovation factors were defined in the mobile ecosystem that was the mother of the 4th industry, and a hypothesis that each factor will affect corporate performance was established. Through the exploratory surveys and interviews, the value proposition of the business model proved to have a positive (+) effect on the financial and non-disaster performance of the company, and the innovation was proved to have a positive (+) effect on the non-financial performance of the company. It was analyzed that the price competitiveness of product innovation had a positive (+) effect on the financial factors of a company, and the initial market entry had a positive (+) effect on the non-financial factors. With this study, we propose the criteria for reviewing the performance of companies that are rapidly competing in the 4th industrial revolution in terms of business model and product innovation.

Smart Grid를 위해서 전기의 끊김없는 공급과 안전한 전기사용이 중요하다. Smart Grid에 사용되는 전기IT기기의 성능평가와 인증을 받기 위해서는 모듈 기준값, 모듈 성능값, 제품별 기능, 실험장비, 허용오차 등 실험 DataBase가 발생한다. 전기IT기기는, 기존의 존기기기에 IT와 통신기능을 융합하여 전기의 공급과 안전성을 강화시킨 제품이다. 본 논문에서는 Smart Grid DataBase 개발을 위한 전기IT기기들을 안전하게 관리하고, IT와 통신을 통한 인터넷 웹브라우저에서 접속할 수 있는 Java Servlet 기술을 이용한, 전기IT기기에 대한 평가기관 및 인증기관이 실시간으로 평가와 인증 자료를 관리 할 수 있도록 한다.
