연구개발 분야의 IT 서비스 전략: e-R&D를 중심으로
이주성,장인수,Lee, Joosung,Jang, Insu 서비스사이언스학회 2012 서비스연구 Vol.2 No.2
e-R&D 활동이란 가상공간에서 인터넷 등의 네트워크나 컴퓨터 소프트웨어를 이용하여 R&D 활동을 전개해 나가는 것을 의미한다. 최근 빠른 속도의 기술변화와 다양해진 고객의 수요로 인해 기업은 생산성 향상의 문제에 직면하면서 e-R&D 필요성을 절감하고 있다. 본 논문에서는 e-R&D의 동향, 적용 사례 및 e-R&D 활성화를 위한 전략적 시사점을 살펴보고, 이를 통하여 미래기업의 e-R&D 모델과 디지털산업 육성 및 기술경쟁력 확보를 위한 e-R&D 정책을 제시하였다. e-R&D means conducting research and development with network or computer software in cyber space. Given the rapid technology paradigm shift and diversified customer needs, companies face the problem of new product and service innovation. This paper introduces the strategic view for e-R&D status, case examples, and e-R&D service. We state e-R&D adoption stages for strengthening the industry competitiveness and IT service utilization.

Distance learning has become an efficient tool and is being widely used at work and in school. This research presents the results of a project-oriented entrepreneurship course taught both in classroom and online for a period of 3 years before and after the pandemic caused by COVID-19. Despite the various challenges, the outcome demonstrated that the students were able to attain required knowledge and capabilities in the online learning environment. As such, this paper discusses effective ways to blend in distance learning components so that both instructors and students can benefit from Internet-based education technologies. In the future, both face-to-face and virtual project work and study are likely to get integrated into a 'hyflex' class, which is flexible, on-offline education.

모바일 보안 영상통신에서의 성능과 에너지 소모량, 화질간의 연관성 분석
이주성(Joosung Lee),문준형(Joonhyung Moon),김수환(Soohwan Kim),박희민(Heemin Park),이경우(Kyougwoo Lee) 한국정보과학회 2013 정보과학회논문지 : 시스템 및 이론 Vol.40 No.3
모바일 내장형 시스템이 널리 사용되면서 다양한 모바일 응용이 등장하였고, 그 중 멀티미디어 응용의 비중이 커지고 있다. 이러한 멀티미디어 응용에서 많이 사용되는 영상통신은 개인 정보는 물론 기밀 정보를 다루기도 하기 때문에 영상 보호의 필요성이 증가하고 있다. 하지만 영상 정보에 대한 부호화/복호화 뿐만 아니라 암호화/해독은 많은 연산을 요구하는 작업이기 때문에 전력 공급이 제한되어 있는 모바일 환경에서는 에너지 소모를 고려해야 한다. 따라서 본 연구에서는 보안 영상통신에서 H.263 TMN 부호기/복호기를 이용한 영상 처리 작업에서 사용되는 매개변수와 보안 알고리즘에서 사용되는 매개변수를 변경하면서 안드로이드 스마트폰에서 실험을 통해 영상의 화질, 실행 시간, 에너지 소모를 측정하고 그들의 관계에 대해 살펴보았다. 실험을 통해 얻은 결과를 토대로 화질의 저하를 최소화 하면서 에너지 소모와 보안 수준을 최대화 하는 방안에 대해 논의한다. Thanks to the advanced technologies, lots of mobile applications have been developed and introduced. Especially, multimedia applications are receiving more attentions since technology advances can allow expensive and complex computations to be executed in mobile embedded systems. The video communication, often used in multimedia applications, occasionally deals with personal information and even classified information. Thus, the encryption of video data becomes indispensable. However, because video coding and cryptography tasks are very complex, they demand high energy consumption. Energy efficiency is the utmost key factor to be considered in mobile platforms due to the limited battery. In this paper, we conduct various experiments such as configuring parameters of H.263 video codec and those of AES cryptographic algorithms in Android-running smartphones. With the experiments, we investigate trade-offs and implications among video quality, run-time performance, and energy consumption. Based on experimental results obtained from this study, we discuss the methods of minimizing the energy consumption while maximizing the video quality and the security level for secure mobile video communications.

시공단계에 참여하는 전문건설업체를 위한 시공 BIM 수행계획 구축
이주성(Lee JooSung),함남혁(Ham NamHyuk),김재준(Kim JaeJun) 한국BIM학회 2015 KIBIM Magazine Vol.5 No.3
For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

Design and management of information and industrial engineering (DMIIE) is a project-oriented junior/senior class that integrates the methodologies of industrial and information engineering in order to solve real-world problems. It examines social issues, engineering approaches to solve the problems and business models that can generate sustainable value for society. This course help students use their engineering knowledge to assess and solve the problems faced by local community. By conducting real-world projects, students get an opportunity to refine their oral and written communication skills. In this paper, the experience of DMIIE course is presented. The effects of the community-based learning for a senior design course are discussed. The possibility of using this blended type of design course to meet the ABEEK outcomes is also stated. <정보산업응용설계 및 경영>은 연세대학교 공과대학 정보산업공학과의 4학년 졸업설계 과목이다. 본 수업은 문제해결을 위한 방법론을 설계하고 적용하는 프로젝트 중심의 캡스톤디자인 과목으로, 최고학년으로서 그 동안 익힌 산업공학, 정보시스 템공학, 공학경영 관련 지식을 종합하여 현장의 문제해결에 활용하게 한다. 프로젝트 결과물은 정보통신기술을 산업공학 분야에 활용한 ‘비즈니스모델’ 또는 ‘서비스모델’의 주요 부분을 구성해야 하며 ‘설계물이 어떻게 해당 기관에 수익을 창출하며 운영될 것인가?’를 명시적으로 보여야 한다. 또한 지역사회경험학습(Community-Based Learning)을 도입하여 비영리기관의 실제 문제를 정보산업공학 지식을 적용하여 해결해 보도록 함으로써 공학이 사회를 위해 도움이 되도록 어떠한 방향으로 쓰여야 하는지 수강생이 느낄 수 있도록 한다. 외부기관 평가, 학생 만족도, 학습성과 평가 결과는 본 수업이 오래되지 않았음에도 ABEEK 산업공학 프로그램 교육성과를 잘 만족시키고 있다는 것을 보여주었다.

R&D 전략의 형태가 기업 재무성과에 미치는 영향에 관한 연구
문희진(Heejin Moon),이주성(Joosung Lee) 한국경영과학회 2010 韓國經營科學會誌 Vol.35 No.1
In Schumpeterian competition, superior profit arises from successful innovation created by firm's R&D strategy. Such R&D strategy diverges as time passes. This study examines empirically the effects of diverged forms of R&D strategy such as technological assets, technological diversity, and technological similarity on firm performance in Korean pharmaceutical industry. With the financial and patent data of 96 firms for 14 years from 1994 to 2007, we measured variables. And then we performed panel analysis with 3 years lag between dependent variable and other variables. The result shows that firm performance increases as technological asset and technological diversification increase. But technological similarity positively affects on firm performance in opposition to our hypothesis. We interpret and discuss these results and highlight the theoretical and practical implications of our findings.

Quaternary Coded Structured Light 와 위상을 이용한 고정밀 Point Cloud 생성 알고리즘
김대욱(Dae-Wook Kim),이주성(Joosung Lee),백승엽(Stephen Baek),이건우(Kunwoo Lee) (사)한국CDE학회 2014 한국 CAD/CAM 학회 학술발표회 논문집 Vol.2014 No.8
3D Scanner is growing industry due to remarkable interests in 3D printing nowadays. To make point cloud, 3D scanner can use many variety ways but generally uses structured light which is uniquely coded binary pattern and reconstructs 3D point cloud through stereo images. We first calibrate the camera, get rectified image, and apply boundary offset at the pre-processing. Using quaternary code on pixels, correspondence can be found roughly. For the purpose of obtaining high-precision point cloud, roughly matched correspondences are corrected with sub-pixel edge detection and phase interpolation. At the post-processing, remove the background and mismatched pixels. Result demonstrates the system has measurement area of 12 × 9㎝², with resolution about 0.06mm.
