This study examines the case of living lab led by intermediary and explores the development possibility as living lab platform. The analyzed cases are 'The Seoul Innovation Park Living lab', 'Korea Senior Living lab' of Seongnam Senior Experience complex, and 'Disaster Safety Living lab'. As a result of the analysis, all three cases have formed a user panel to form a living lab platform, and provide living lab service to internal and external organizations. A common feature that combines a technology platform with a 4Ps-based governance platform is identified. However, the characteristics, the meaning, and the process are different from case to case. In the future, the living lab platform needs to share learning experiences that are going on individually, since domestic living lab platform is in the early stage. Through this, it is necessary to seek collaboration and cooperation with related similar projects, and to jointly promote institutional and physical infrastructures related to living labs.

2001년에는 저가의 보급형 미니랩이 출시되어 기존 제품의 수요가 이미 소진됐다는 것을 반증했으며, 2002년에는 보급형 기종간의 경쟁이 치열할 것으로 예상된다. 국내 아날로그를 포함한 전체 미니랩기기는 약 7천연대로 추정되며 현재까지 디지털 미니랩이 170여대로 아날로그 기기를 대체하는데 시장 확대 수요는 많은 여유가 있다고 예상된다.

This article suggests Living Lab approach as a technology commercialization model of public research and development (R&D) projects. Living Lab is a model for end-users, private companies, research institutes, and public organizations to develop technology in a living space which works as a laboratory. Unlike the dominant technology commercialization model which focuses on private enterprises, a new living lab model discusses end-user centered commercialization. Based on general living lab model, three types of technology commercialization model are suggested. The 'Demand exploring type living lab' and the 'Problem solving type living lab' are project-based living lab. The other type of living lab is 'Living lab platform'. The projectbased living lab can be utilized as modules when promoting R&D projects. On the other hand, the living lab platform is infrastructure to provide living labs services to companies, public institutes and municipalities.

The chirp spread spectrum (CSS) technique spreads the data signal over a frequency bandwidth wider than minimum required bandwidth. By using time overlapping, the bit rate in CSS can be increased. However, for reliable transmission of data signal, the intersymbol interference (ISI) due to overlap should be analyzed. In this paper, the relation between the degree of overlap and ISI is analyzed in direct modulation binary phase shift keying CSS systems. In some cases, the overlap does not incur ISI at all and the ISI fluctuates or monotonically increases as the number of overlaps changes. It is also shown that the simulation results closely agree with the analytic results.

Living Lab is being introduced and applied as an innovation model driven by social entities (residents, users, etc.) and as an innovation place based on local and field. This study analyzed three living lab cases of Bukchon IoT living lab, Seong-Daegol energy transition living lab, and Daejeon Geonneoyu project, which were designated as 'Living Lab' to solve local problems. We analyzed the local problem, the problem solving goal, the role of each participant and the subject, the living lab promotion system, the significance in each case. In addition, the types and characteristics of living labs were elucidated and future development plans were discussed. The result is as follow. First, each case has a tendency to link science technology and ICT with local problem solving though there is a difference between the technologies used. Second, local residents played a leading role in the whole living lab process from problem identification to technical experimentation, diffusion and application. Third, the role of the intermediaries commonly played an important role in the operation of the living lab. Last but not least, each case has different types of living lab. Bukchon IoT living lab being operated as a project by the government / municipality to create a living lab activity-base or to support actors' activities. On the other hand, the Seong-Daegol energy transition living lab and Daejeon Geonneoyu project were conducted by the civil society itself to define problems and explore technologies in order to solve local problems.

국내에 처음 완전 디지털 미니랩 장비가 출시된 것은 불과 5년 전. 2001년부터 보급된 디지털 미니랩은 연평균 2배 이상의 성장을 기록하며 사진출력시장을 견인하고 있다. 관련 업계에 따르면 현재 국내에 보급된 미니랩 장비는 작년 말 기준으로 총 3400여대로 이중 디지털 미니랩이 차지하는 비율을 메이커마다 제시하는 수치에 있어 다소 차이가 있지만 대략 60% 정도인 2000여대로 추정된다. 올해는 남아있는 아날로그 사진관에 디지털기기보급의 마지막 해가 될 것으로 보이며 메이커들은 마지막 시장 선점을 위해 저가의 보급형 기종을 내세워 치열한 판촉경쟁을 벌일 것으로 보인다.

Wrap accounts are customized financial services for which investment companies and stock brokers manage investors assets based on their preferences. The success of wrap accounts depend upon the accurate understanding of investment risk propensity and the proper designing of financial portfolio. To this end investment companies should accurately measure investors investment risk propensity with calibrated measures. There, unfortunately, exist few highly calibrated measures of investment risk propensity. Therefore the practices of marketing strategies and customer management often turn out to be less effective and fragile to competition. The purposes of this present study aim to understand the investment risk propensity of wrap accounts customers, to help classify the customers based on the degree of the investment risk propensity, and to implement relevant marketing strategies for different groups of customers. Based on previous studies, two hypotheses were delineated and verified. The findings of the study should help differentiate prospective customers into unique and accessible segments for further targeting and positioning wrap account markets.
