Due to the development of construction technology, there is a considerable increase in the number of skyscrapers in the world. Accordingly, there are rapid growing requests about maintenance systems such as cleaning, painting, and monitoring the processes of facade in highrise buildings. However, it is extremely dangerous working the walls of high-rise buildings, and crashes from buildings have accounted for large proportion of constructional accidents. An alternative solution must be developed with the commercialization of automatic robot systems. For the last decade, interest in developing robots for cleaning and maintenance in facade of highrise buildings has continuously increased. The use of automatic robot systems can be expected to reduce accidents and decrease labor costs. In this paper, we propose a new kind of cleaning mechanism. We have designed and manufactured various cleaning tools for different types of facades with economic commercialization. The cleaning cycle, size, and intensity will be determined by economic constraints as well. The final goals are to design and manufacture tools and robots that can clean facades efficiently and rapidly even in dangerous places. The cleaning tool systems consist of nozzles, brush rollers, and squeezing devices. Furthermore, these tools and robots perform each process utilizing the systems of built-in guide types and gondola types for building maintenance. The performance of the proposed cleaning tools is evaluated experimentally; however additional study should be necessary for safer and more stable commercialization.

본 연구에서는 Porter의 다이아몬드 모형에 입각하여 관련 분야 전문가들의 의견 수렴을 통해 우리나라 인공지능 산업의 국가 경쟁력에 영향을 미치는 요인들에 대한 중요도를 분석하였다. 분석 결과 인공지능 산업의 국가 경쟁력에 가장 큰 영향을 미치는 요인은 연구개발, 자본, ICT 기술 경쟁력 순으로 나타났다. 인공지능 산업은 자본집약적 특성이 강한 하이테크놀로지 산업이므로 국가경쟁력 확보를 위해 무엇보다 인공지능 기술과 그 기반인 정보통신 기술에 대한 국가 R&D 역량의 결집과 인프라 구축을 위한 공격적인 투자가 중요할 것으로 판단된다. 인공지능 기술의 근간을 이루는 ICT 인프라 및 활용역량 등을 고려할 때 국내 소비자의 높은 요구수준은 인공지능 산업의 국가 경쟁력 확보에 긍정적 촉매요인으로 작용할 것으로 예상된다. 또한, 인공지능 기술은 빠른 확산속도와 강한 파급력을 지닐것으로 전망되므로 적시 대응을 위한 기업의 선제적 역량확보가 필수적일 것으로 사료된다.

2005년 7월 연구소기업 제도 시행 이후 연구소기업 설립이 빠르게 증가하면서 연구소기업은 공공기술사업화의 대표적인 모델이자 경로로 자리매김하게 되었다. 연구소기업의 양적 성장과 함께 공공기술사업화와 관련한 국가 정책, 기관 전략 등에 있어 연구소기업의 중요성도 증가하여 왔지만 지난 16년 간 연구소기업의 설립 및 성장은 시기별로 매우 다른 양상으로 진행되어 왔다. 본 연구에서는 양적 팽창기라고 할 수 있을 정도로 연구소기업 설립(등록)이 급격히 증가하기 시작한 2014년 전후의 비교를 중심으로 지난 16년 간 연구소기업의 변화를 비교·분석하였다. 이를 위해 본 연구에서는 2014년 이후 연구소기업의 급격한 증가원인을 정책, 제도, 창업환경, 성장환경 변화로 나누어 다각적으로 분석하고, 양적 팽창기 이후 연구소기업 변화가 연구소기업 성과 및 성장에 미친 영향을 분석하였다. 분석 결과 양적 팽창기 초기에는 연구소기업 관련 정책 변화와 이에 따라 시행된 연구소 기업 발굴·기획 지원 사업 등이 연구소기업 증가의 주요 요인으로 나타났다. 또한 2016년 이후의 연구소기업 설립(등록)의 급격한 증가는 산학연협력 기술지주회사의 확대, 기술지주회사의 투자 여건 개선 등과 같은 연구소기업 창업 환경 변화의 영향이 큰 것으로 나타났으며, 2019년 이후에는 공익법인 등 연구소기업 설립 주체의 확대와 강소특구 지정 등 제도 변화가 연구소기업 설립 증가에 영향을 미친 주요 요인이었다. 또한 양적 팽창기를 전·후로 하여 연구소기업 성과 및 성장 특성의 변화를 분석한 결과 연구소기업 등록 시점과 연구소기업 자본금 규모는 등록 이후 3년 간의 평균 매출액에 통계적으로 유의미한 영향을 미치는 것으로 나타났다. 이러한 결과는 2014년 이후 연구소기업의 급격한 증가와 함께 연구소기업의 중요성이 커졌지만 한편으로는 양적 팽창기 이전과 비교하였을 때 연구소기업 특성에 변화가 있었으며, 규모별(소형, 중·대형) 또는 성장 단계별 연구소기업 지원 체계 구축의 필요성이 더 커졌음을 보여준다.

We have developed a novel crystallization process, where the crystallization temperature is lowered compared to the conventional RTA process and the metal contamination is lowered compared to the conventional VIC process. A very-thin a-Si film was deposited and crystallized at $550^{\circ}C$ for 3 h by the VIC process and then a thick a-Si film was deposited and crystallized by the RTA process at $680^{\circ}C$ for 5 min using the VIC poly-Si layer as a crystallization seed layer. The RTA crystallized temperature could be lowered up to $50^{\circ}C$, compared to RTA process alone. The poly-Si film appeared a needle-like growth front and relatively well-arranged (111) orientation. In addition, the Ni concentration in the poly-Si film was lowered to $3{\times}10^{17}\;cm^{-3}$ and that at the poly-Si/$SiO_2$ interface was lowered to $5{\times}10^{19}\;cm^{-3}$. The reduction in metal contamination could be greatly helpful to achieve a low leakage current in poly-Si TFT, which is the critical parameter for commercialization of AMOLED.

There has been growing interest and rapid development in transparent electrode films, which are flexible and light and used in mobile, simple information, and electronic devices, and based on recent advancements in nano technology, information technology, and display technology. In particular, studies on developing such films with both high conductivity and high transmittance of visible rays are highly in demand for commercialization. In this study, transparent electrode films were developed for IT using micro patterns that show sheet resistance less than 10 Ω/□, adhesive strength more than 98%, and light transmittance more than 90%. The results of applying a surface emission gradient minimization (Honey Comb) technology to the films was the verification of the sheet resistance, adhesive strength, and light transmittance satisfying the target level of this study through Imprinting and Remolding processes.

Due to rapid developments of IT technologies, convergence services like IPTV (Internet protocol television) are shown up. Even though expert and customer had great expectations for this innovative service, commercialization was delayed for years by the legal dispute between industry players. One of the biggest problems was that whether internet backbone providers have to share their internet network backbone with IPTV service providers (which don't have network backbone) or not. As other countries, Korean government set the rules that ISP have to offer indiscriminate access to other IPTV service provider. At the same time, internet backbone providers can charge access charge based on cost by way of compensation. Thus access charge is very critical to the IPTV industry players. The objective of this paper is to provide model that can calculate the reasonable access charge by system dynamics, based upon real data in Korean telecommunication industry.

The thermophilic aerobic digestion (TAD) process is recognized as an effective method for rapid waste activated sludge (WAS) degradation and the deactivation of pathogenic microorganisms. Yet, high energy costs due to heating and aeration have limited the commercialization of economical TAD processes. Previous research on autothermal thermophilic aerobic digestion (ATAD) has already reduced the heating cost. However, only a few studies have focused on reducing the aeration cost. Therefore, this study applied a two-step aeration control strategy to a fill-and-draw mode semicontinuous TAD process. The NADH-dependent fluorescence was monitored throughout the TAD experiment, and the aeration rate shifted according to the fluorescence intensity. As a result, the simple two-step aeration control operation achieved a 20.3% reduction in the total aeration, while maintaining an effective and stable operation. It is also expected that more savings can be achieved with a further reduction of the lower aeration rate or multisegmentation of the aeration rate.

In a knowledge economy, accelerating the pace of knowledge building and the rapid acquisition of knowledge are keys to innovative development. However, the development of the commercialization of research results and formation of new start-up companies are often not as active as they should be with a lack of motivation and incentive being one of the contributing factors for the failure to take action. In Taiwan and Japan, the reason that widely advocated idea of industry-academia collaboration is to help advance the technological capabilities of research and development as well as produce economic benefit. The assistance rendered by the government during the transformation and the assessment of outcomes from entrepreneurial pursuits are key issues explored in this study. The results indicate that the network system in the national innovation system is important for entrepreneurship development. The domestic market of Taiwan is not as large as Japan and new entrepreneurs have to face global market challenges.

Since 3DTV was introduced, the market could not grow further due to the several causes such as the lack of content, technology for production and display and eyestrain. However, the rapid advances of the technologies on digital broadcasting, consumer electronics and computer enabled the commercialization of 3D animation, computer graphic, 3D advertising as well as 3D movies, and since then the international technical competition is growing fiercer. Since much more companies introduced the solutions for 3D in NAB 2010 than 2009, the expected size of the market will be bigger than ever before. This article describes the recent trends and the prospect of the 3D technologies including national defence strategy, content, construction, consumer electronics, advertisement, and terrestrial 3D1V pilot project in Korea.
