Firms are increasingly adopting online communities-of-practice (CoPs) with strong managerial support in hopes of promoting knowledge sharing and creation within the organization. Excessive managerial concern and sponsoring, however, could harm the spontaneity of CoP participants, which is one of the pivotal characteristics of virtual communities, and in the end, have negative impact on their smooth operation. In this regard, this study examines the factors which affect the stimulation of CoPs and explores the difference in their operating mechanisms under two differing organizational structural settings by the existence of a sponsor. By analyzing 133 samples of CoPs in a globally leading company, this study found that the existence of a sponsor designated by the organization, has serious influence on the working of CoPs, That is, leaders' enthusiasm and the level of off-line activities are critical factors for the stimulation of CoPs which have no sponsor, while in case of CoPs that have their sponsors, neither leaders' enthusiasm nor the level of off-line activities are significantly related to the stimulation of CoPs. At the same time, the performance of CoPs which have their sponsors was found significantly higher than that of CoPs which have no sponsor. These results indicate that firms need to pay special attention to organizational sponsorship when introducing CoPs within their organizations.

This study aims at examining each firm's decision-makings of complex product and system (hereafter CoPS) innovation strategy, so that it tries to reveal the nature and role of CoPS innovations strategy. And it designed a comparative case study along with qualitative methods, by having two mobile operators' digital rights management (hereafter DRM) innovation in South Korea's digital music service industry. Through literature review, this study formulated three research propositions: (i) Each firm's decision-makings of CoPS innovations strategy are analytical negotiation process among economic actors in an industry; (ii) Each firm's market power originated from its market share from the installed base through network effect and switching cost influence decision-makings of CoPS innovation strategies; (iii) Each firm's decision-makings of different CoPS innovation strategies are related to their intension of achieving better market power, consequently dominant design. Through empirical examination of two mobile operators' decision-makings of DRM innovation strategy, this study empirically verified three research propositions.

Korean manufacturing industry have recently faced the catch-up of China in the mass commodity product, such as automotive, display, and smart phone in terms of market as well as technology. Accordingly, discussion on the importance of achieving catch-up in complex product systems (CoPS) has been increasing as a new innovation engine for the industry. In order to achieve successful catch-up of CoPS, we explored emerging technologies of CoPS, which are featured by the characteristics of radical novelty, relatively fast growth and self-sustaining, through the study of emerging technologies of gas turbine for power generation. We found that emerging technologies of the gas turbine are technologies for combustion nozzle and composition of electrical machine for increasing power efficiency, washing technology for particulate matter, cast and material processing technology for enhancing durability from fatigue, cooling technologies from extremely high temperature, interconnection operation technology between renewable energy and the gas turbine for flexibility in power generation, and big data technology for remote monitoring and diagnosis of the gas turbine. We also found that those emerging technologies resulted in technological progress of the gas turbine by converging with other conventional technologies in the gas turbine. It indicates that emerging technologies in CoPS can be appeared on various technological knowledge fields and have complementary relationship with conventional technologies for technology progress of CoPS. It also implies that latecomers need to pursue integrated learning that includes emerging technologies as well as conventional technologies rather than independent learning related to emerging technologies for successful catch-up of CoPS. Our findings provide an important initial theoretical ground for investigating the emerging technologies and their characteristics in CoPS as well as recognizing knowledge management strategy for successful catch-up of latecomers. Our findings also contribute to the policy development of the CoPS from the perspective of innovation strategy and knowledge management.

학습공동체는 지식의 효율적 공유를 위해서 다양한 분야에서 강조되고 있다. 학습공동체의 중요성과 이의 활성화에 대한 연구는 많이 이루어지고 있다. 그러나 학습공동체를 평가하고 전략을 제시하고자 하는 연구는 거의 이루어지지 않고 있다. 학습공동체를 평가하고자 하는 연구는 이루어지고 있을지라도 단순 평가가 전략을 제시하는 수준으로는 이어지지 않고 있다. 따라서 본 연구에서는 학습공동체를 지식흐름을 토대로 진단하고 이를 토대로 전략을 제시하고자 한다. 교육기관에서는 지식의 전이와 공유를 위해서 학습공동체를 다양한 형태로써 활용하고 있다. 지식흐름을 진단하기 위한 프레임워크를 사회연결망분석을 기반으로 제시하고, 이를 교육기관에 적용함으로써 본 연구의 적용가능성 및 유용성을 검증하고자 한다.

"공공기록물관리에 관한 법률"에 따르면 모든 공공기관은 최소 1명 이상의 기록물관리 전문요원을 배치하여야 하지만 현재 교육지원청 및 군 관련 기관들은 다른 기관에 비해 배치 실적이 저조한 실정이다. 그 중 일부 교육지원청에서는 그러한 문제점을 타계하기 위해 '기록관리 학습동아리(CoP)'를 운영하고 있었다. 이에 대한 운영 실태를 파악하기 위해 정보공개를 통한 전국 교육지원청을 전수 조사, 동아리의 현황을 분석하였으며 동아리의 존재/부존재 기관을 나누어 설문조사를 진행하였다. 분석 결과, 기록관리 학습동아리가 실질적인 기록관리업무 수행과 개인의 능력 향상에 도움이 되고 있음을 확인할 수 있었다. 반면 기록물관리 전문요원이 배치될 때까지 동아리가 한시적으로 기록관리업무를 일부 수행한다 할지라도 근본적으로는 기록물관리 전문요원을 충원하여 체계적인 기록관리가 이루어질 수 있도록 조치해야 한다는 의견이 수렴되었다. 또한 기록관리 학습동아리 운영상의 장애요인을 도출하고 이를 해결하기 위한 활성화방안을 제안하였다.

Prior studies on knowledge sharing have concentrated primarily on either organizational or individual characteristics. However, by focusing on the interaction between members in On-line communities of practice (CoPs), we seek to identify and analyze factors that affect knowledge sharing by members in CoPs. Therefore, we examine if the independent variables such as interactivity, followership, and trust have positive impacts on the dependent variables such as commitment to CoPs and intention to share knowledge. In addition, this study also investigates the relationship between commitment to CoP and intention to share knowledge. The empirical results show that interactivity has a positive impact on commitment, but an insignificant impact on intention to share knowledge. Besides, trust between members is significantly associated with intention to share knowledge, whereas it does not have a significant effect on commitment. Moreover, followership is significantly related to both commitment and intention to share knowledge. These empirical findings show that the relationship between members in CoPs play a significant, positive role in intention to share knowledge. In conclusion, this research contributes to shedding a light into both interactions between members in and commitment to CoPs that are critical to facilitate knowledge sharing.

이 논문은 제도적 관점에서 미국의 위성산업 사례를 통하여 복잡한 제품시스템(CoPS)의 공진화 과정을 살펴본다. 이는 공진화의 자세한 기술이라기보다는 그것의 주요 특징들을 이해하는 작업니다. 위성산업은 수출통제제도와 상호작용하며 국가안보와 산업경쟁력을 둘러싼 경쟁적인 입장들이 대립하는 상태에 있다. 역사적 제도주의와 행위자중심 제도주의 관점에서 미국 위성산업 사례를 분석해 보면, 냉전이후 미국의 위성산업과 제도의 경로는 지속적으로 산업경쟁력 지향 속에서 제도 도전자와 방어자들의 상호 대립적이면서도 타협적인 제도수정의 결과물이다. 결과적으로 국가안보의 제도 규칙은 변경되었으며, 이는 냉전이후 위성산업의 시장화의 경로를 다지는데 기여하였다.

Polystyrene-co-divinylbenzene (PS-co-DVB) asymmetric membranes were prepared. In order to control their structure and mechanical properties the degree of cross-linking and the composition of casting solution were varied. The rubber added PS-DVB membranes was also prepared to overcome the mechanical limitation of cross-linked membrane, and their mechanical properties were investigated. It was revealed that the concentration of polymer in the casting solution affected the determination of skin formation. When the PS-co-DVB membrane consists of styrene-butadiene (SB) rubber or liquid polybutadiene (PBD), the structures formed showed that the PS content in the PS/DVB system played an important role in determining the porous sublayer structure.

Macroazoinitiator를 이용하여 Polystyrene-poly(caprolactone) (PS-PCL) 블록공중합체를 합성하고, poly(2, 6-dimethyl-1, 4-phenylene oxide) (PPO)/poly(styrene-co-acrylonitrile) (SAN, acrylonitrile의 함량이 25wt%) 블렌드에서의 상용화 효과를 조사하였다. 공중합체 중 PS블록과 PCL블록은 각각 PPO, SAN과 상용성을 가졌으며, 블록공중합체는 SAN의 PPO 영역으로의 용해 정도를 증가시킴을 관찰할 수 있었다.

본 연구는 탈묵펄프 공정의 과산화수소 보존표백시 과산화수소 안정제 Versenate PS에 의한 silicate 대체효과를 검토하였다. 대체 가능성을 파악하기 위하여 silicate 및 Versenate PS 처리 표백시 전처리와 가성소다의 최적화 실험을 시행한 후 잔류 과산화수소의 함량과 백색도를 측정하였다. 얻은 결과를 요약하면 다음과 같다. 1. Silicate 처리 표백시 가성소다의 최적농도는 2.5~3.0%였다. 2. Versenate PS처리 표백시 가성소다의 최적농도는 1.0~1.5%였다. 3. Versenate PS 단독 처리만으로는 만족할 만한 표백효과를 나타내지 못했다. 4. Versenate PS 처리 표백시에는 silicate양을 상당량 줄일 수 있다. 5. DTPA로 전처리 하는 것이 좀 더 높은 표백효율을 나타내었다.
