추천시스템과 소셜 네트워크를 융합한 지능형 연구자연결망 구축
이충무,이상기,이병섭,Lee, Choong-Moo,Lee, Sang-Gi,Lee, Byeong-Seop 한국과학기술정보연구원 과학기술정보센터 2009 Journal of Information Science Theory and Practice Vol.40 No.1
개방, 참여, 공유에 기반한 웹 2.0 사상이 다양한 분야로 빠르게 확산되고 있으며, 개인화 기능인 추천시스템과 소셜 네트워크에 관한 연구가 활발하다. 추천시스템과 소셜 네트워크의 경우 각기 다른 영역에서 독자적으로 발전하여왔으며 이들을 융합한 새로운 형태의 서비스모델에 대한 연구는 미미한 실정이다. 본 논문에서는 이용로그, 개인프로파일, 북마크 등을 분석하여 자신과 유사한 분야를 연구하는 연구자를 지능적으로 추천하여 효율적으로 소셜 네트워크를 구성할 수 있는 연구자연결망을 구축하였다. 이를 통해 기존 소셜 네트워크 문제인 초기 네트워크 구축의 어려움과 이용자들의 소극적인 참여로 인한 네트워크 확장성 문제를 해결하였다. The web 2.0 concept rapidly spreads to the various field which is based on an opening, the participation, and a share. And the research about the recommendation system, that is the personalize feature, and social network is very active. In the case of the recommendation system and social network, it had been developing in the respectively different area and the new research toward the service model of a form that it fuses these is insignificant. In this paper, I'm going to introduce efficient social network which is called the researcher connection network. It is possible to recommend the researcher intellectually who studies the similar field by analyzing the usage log and user profile. Through this study, we could solved the network expandability problem which is due to the user passive participation and the difficulty of the initial network construction that is the conventional social network problem.

연극공연상품의 온라인 구매의도에 정보 내용 및 품질이 미치는 영향
이충무 ( Choong Moo Lee ),조세영 ( Se Hyung Cho ) 한국연극교육학회 2011 연극교육연구 Vol.19 No.-
The purpose of this study is to find the desired contents and quality of information provided by websites executing e-commerce of play performance commodity. With the growth of internet business, on-line sites play an important role in the field of performing arts not only as a box office but also as an useful information system. As a result, both information contents and quality can be regarded as one the most important factors to the customers who want to get various types of information and buy tickets. In this context, this study is focused on four meaningful aspects: first of all, on-line purchase intention depends upon such contents as synopsis, casts, director, and reviews of other audience; secondly, consumer involvement gives moderating influences on the relationship between information contents/quality and on-line purchase intention; thirdly, the basic information such as time, place and price does not significantly influence on the on-line purchase intention ; lastly, the quality of information becomes one of the most influential factors irrespective of the level of consumer`s involvement. The results of this study can be used for three different areas: 1) for practical reference material in building marketing strategy; 2) for knowledge source in educating marketing and information systems of performing arts; 3) for interdiscilplinary study of culture and arts, management and MIS.

Dry Sorbent Injection 에 의한 배가스 처리 : Calcium 계와 금속산화물 흡착제를 이용한 HF 제거
이충무(Choong Moo Lee),오세천(Sea Cheon Oh),이해평(Hae Pyeong Lee),김희택(Hee Taik Kim),류경옥(Kyong Ok Yoo) 한국화학공학회 1999 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.37 No.3
In order to reduce HF in a flue gas via DSI process, the HF removal efficiency of calcium-based sorbent was investigated. By using gas chromatography the effluent gas exited from fixed-bed reactor was analyzed at temperature range of 250-950 ℃. Also BET, XRD, SEM/EDX, DLS and TG/DTA were carried out to certify the reaction mechanism. HF removal efficiency was maximum at 750 ℃ and decreased above this temperature because of specific surface area reduction resulted from structural changes of sorbent. Reactivity of sorbent was proportional to initial concentration of HF and flow rate of 150 ㎖/min showed the highest removal capacity. In addition, HF removal efficiency of various metal oxide sorbents such as Al₂O₃, Cu₂O, Fe₂O₃, MgO, TiO₂and ZnO was studied. As a result, Fe₂O₃ showed an excellent removal capacity in this study.

온라인 구매사이트의 정보콘텐츠가 정보서비스만족도 및 구매의도에 미치는 영향
조세형(Se-Hyung Cho),이충무(Choong-Moo Lee) 한국콘텐츠학회 2012 한국콘텐츠학회논문지 Vol.12 No.7
정보통신기술의 발달로 온라인 시장에서 제공되는 영화상품의 정보콘텐츠는 고객의 구매의사결정에 많은 영향을 미치고 있다. 본 논문의 목적은 정보콘텐츠의 내용이 영화상품 구매고객의 정보서비스만족도와 구매의도에 어떠한 영향을 주며, 이러한 영향이 영화상품에 대한 고객관여도에 따라 어떻게 변화하는지를 실증분석을 통해 밝히는데 있다. 연구결과는 다음과 같다. 첫째, 온라인에서 제공되는 정보콘텐츠의 정보서비스만족도는 관람정보(시간, 장소, 가격, 구매방법)보다는 내용정보(줄거리, 배우, 관람후기)가 고객관여도 수준에 관계없이 유의적 영향을 미친다. 둘째, 고객의 온라인구매의도에는 관람정보와 내용정보 모두 영향을 미친다. 고객관여도가 낮은 경우는 관람정보가, 높은 경우에는 내용정보가 유의적 영향을 미치는 것으로 나타나 조절효과를 보여주었다. 셋째, 정보서비스만족도는 고객관여도의 수준과 상관없이 온라인구매의도에 강력한 영향을 준다. 결국, 고객의 만족도를 높이기 위해서 내용정보의 다양성과 품질 제고가 필요하며 온라인구매의도를 높이기 위해서는 내용정보와 더불어 관람정보의 개선도 필요하다는 것을 보여주었다. 이러한 연구 결과는 영화상품의 온라인구매사이트를 통한 마케팅전략 수립에 도움이 될 것으로 기대된다. The purpose of this study is to clarify the impact of information contents at online purchase sites of movie merchandise. The results of this study are as follows: 1) Movie-understanding information(synopsis, actors, reviews) has a meaningful influence on information service satisfaction irrespective of consumer involvement; 2) Movie-understanding and movie-going information(time, place, price, purchasing method) are alike in having a meaningful influence on online purchasing intention. However, movie-going information has a meaningful influence in case of lower consumer involvement, while movie-understanding information has a meaningful influence in case of higher consumer involvement.; 3) Information service satisfaction gives a strong influence on online purchasing intention irrespective of the level of consumer involvement. In conclusion, there is a need to improve diversity and quality of movie-understanding information to enhance consumer satisfaction. Also, it will be necessary to improve movie-understanding and movie-going information in order to enhance online purchasing intention. These results are expected to give an insight to build a creative marketing strategy of online purchase sites of movie merchandise.

이인열(In-Yol Yi),이강일(Kang-Il Lee),심충무(Choong-Moo Shim),최대규(Dae-Kue Choi),임재규(Jae-Kyoo Lim) 한국조명·전기설비학회 2012 조명·전기설비학회논문지 Vol.26 No.11
Most of existing wind turbine system is used with geared type; however, this type has lots of problems which are noisy, weight, maintenance and so on. In this paper, wind turbine system with fluid torque converter applied to solve these problems. In case of the proposed wind turbine system, it is possible to transmit torque to adaptable distance. So various sets including generator, inverter and auxiliary motor move from the nacelle to the ground. As a result, Total weight in Nacelle can be decreased. however, the efficiency can be decreased with fluid tourque system.. We also applied auxiliary motor to fluid touque system . So, we also realized rated revolutions and rated output windturbine and could get considerable good data.
