Technology diffusion policy can be defined as the role of government in linking knowledge production with usage. It has an importance due to the fact that linking knowledge between the producing agent and using agent does not automatically occur. If knowledge produced by an R&D agent is not used by somebody else, the knowledge may deteriorate to a social loss since knowledge production consumes a considerable degree of social resources. Explicit technology diffusion policies are not found in Korea. There we, however, a number of implicit policies to promote technology diffusion, mainly by promoting cooperation among universities, industries and research institutes. Government R&D programs have provided incentives for cooperative research projects, and many government sponsored institutes have been assigned the role of technology assistance for small and medium sized firms. Nevertheless, diffusion policies remain weak in comparison to other innovation and technology policies. This is reflected in the relatively small scale of government support for technology diffusion programs. In addition, there is no systematic approach between the different ministries for enhancing diffusion across technologies, institutions, sectors and regions. A comprehensive evaluation of government diffusion programs, which is necessary for improving policy and program design, is lacking. Enhancing the diffusion of technology in Korea will require the strengthening of policies at different levels, including; 1) increasing the orientation of science and technology policies towards diffusion; 2) increasing the scale of existing diffusion programs; 3) developing new diffusion programs, in particular sector-specific or manpower training programs; 4) developing policies to encourage a culture of cooperation that can facilitate technology diffusion; and 5) carrying out substantial policy research to develop diffusion policies.

기술정책은 신기술 확산에 영향을 주는 중요한 요인 중의 하나이다. 본 연구의 목적은 기존의 전염병 확산 모형을 기초로 정책변수를 추가한 신기술 확산모형을 구축하고, 미국에서의 이산화탄소 배출 감소에 응용되는 고체조명(Solid-State Lighting) 기술을 사례로 실증연구를 진행하는 것이다. 실험결과, 정책변수는 정(+)의 영향을 미치는 것으로 나타났으며, 기술정책은 신기술의 확산에 추진 작용을 하는 것으로 나타났다. 이는 정책적 역할에 대한 정량적 이해를 도모하는데 있어서 정량적 판단을 위한 자료를 제공하고, 정책변수와 신기술 확산의 정량적 관계를 파악하는 데 도움이 될 것이다.

As cost invested in developing the specified technology is increasing, investors are paying more attention to cost to benefit analysis (CBA). One of the basic elements of CBA for new technological development is the diffusion pattern of demand of such technology. Many studies of technology evaluation have adopted a single generation model to simulate the diffusion pattern of demand. This approach, however, considers the diffusion of the new technology itself, not taking into account a newer generation that can replace the one just invented. In this paper, we show how a multi-generation technology diffusion model can be applied for more accurate CBA for information technology. Monte Carlo simulation is performed to find influential factors on the CBA of a Cybernetic Building System.

단세대 기술의 확산 거동에 대한 이해는 시간의 변화가 주요한 확산 인자로 고려되었으나, 다세대 기술의 확산거동은 시간의 변화 외에 다양한 인자들을 고려할 필요가 있다. 본 연구에서는 다세대 기술의 확산경로를 분석하기 위해 가격 및 기술적 성능의 추가적인 인자들을 발굴하여 '시간, 가격, 성능' 차원의 확산경로를 정의하였고, 정의된 다차원 확산경로를 바탕으로 다세대 기술인 반도체 산업에 대해 확산경로를 추적하였다. 반도체 산업에 대한 사례 연구 결과 기술 확산경로는 '가격과 기술적 성능으로 구성되는 면적이 최대한 커지는 방향'으로 확산되는 거동을 보였다. 본 연구는 다세대 기술의 확산 거동을 다차원에 기반하여 분석하였고, 성숙 및 초기 단계의 다세대 기술들의 확산 거동에 대해 예측 가능하다는 이론적 의의를 지니고 있다. 또한 다세대 기술 산업의 연구개발 및 마케팅 담당자들에게도 시장 진입 및 퇴출 시기, 고객의 경제적 및 기술적 요구조건 파악을 위해 실무적으로도 의의가 있다.

Many researchers have studied the theme on CASE technology. However, there are no many researches which lightened the diffusion of CASE technology and organizational change. The purpose of this study is to investigate the factors that influence on the diffusion of CASE technology and the way how IS organization changes as a result of the diffusion. We exploited a case study research as a methodology. We selected five software development firms which possessed the leading IS technology abilities as the case companies. We realized that the diffusion of CASE technology proceeded under the three context variables - managerial context of information systems, the intent and behavior of key players and implementation strategy of organization - to enhance the performance of information systems. The contribution of this study is to clarify the change of IS organization as a result of CASE technology diffusion. This study has the limitation that tried to analyze the organizational change only in a direction.

기술의 확산 현상의 추세 및 발생 동인에 대한 정확한 이해는 새로운 기술을 예측하고 기술 혁신의 과정을 이해하는데 매우 유용하다. 본 연구에서는 기술의 진화 속도가 빠른 반도체 산업 32nm, 22nm, 14nm 로직 기술의 실증적 사례에 대해 기술적 성능 향상 및 경제성 지표를 고려한 정량적 추세 분석을 적용하여 기술 확산 현상의 추세 및 발생 동인을 분석하였다. 기술적 성능 향상을 고려한 기술 확산 곡선은 S곡선의 성숙기, 쇠퇴기 형태를 보였고, 경제성 기반 기술 확산 곡선은 학습효과곡선의 형태를 보였다. 기술 확산 곡선은 2년의 수명주기를 보였고, 기술 세대별 기술적 성능향상 또는 칩 제조비용의 변화 정도가 정량적으로 관찰되었다. 또한 제품구조혁신은 경제적 발생동인보다 기술적 발생동인이 더 지배적인 영향을 미침을 확인할 수 있었다. 본 연구결과는 첨단기술기반의 반도체 산업에 대한 기술 확산 현상의 추세 및 발생 동인에 대한 실증연구로 시사점이 있으며, 기술 예측 또는 기술 전략 수립에 활용될 수 있으므로 실무적으로도 의의가 크다.

The Internet possesses not only features of mass media but also features of word of mouth communication. Communication channel is considered as one of most important variables in diffusion process. In this paper, we examined functionality of technology diffusion on the Internet through the use of meta tags. We have measured the coefficients of the Bass diffusion model which has been well-established in new product diffusion. This research shows that the Bass model is appropriate for describing technology diffusion on the Internet. The external influence as represented by the coefficient of innovation was found to be much smaller while the internal influence dominates in all meta tag diffusion. In meta tag diffusion, the internal influence as represented by the coefficient of imitation was increased at least twice bigger than that of consumer durables and information technology. Collecting necessary data in social sciences research can be a burden. This research shows that it can be alleviated through the use of software agents over the Internet. The research made use of software agents for collecting longitudinal data from publicly accessible archive such as Archive.org.

During the last decade, the security of digital images has received considerable attention in various multimedia transmission schemes. However, many current cryptosystems tend to adopt a single-layer permutation or diffusion algorithm, resulting in inadequate security. A hierarchical bilateral diffusion architecture for color image encryption is proposed in response to this issue, based on a hyperchaotic system and DNA sequence operation. Primarily, two hyperchaotic systems are adopted and combined with cipher matrixes generation algorithm to overcome exhaustive attacks. Further, the proposed architecture involves designing pixelpermutation, pixel-diffusion, and DNA (deoxyribonucleic acid) based block-diffusion algorithm, considering system security and transmission efficiency. The pixel-permutation aims to reduce the correlation of adjacent pixels and provide excellent initial conditions for subsequent diffusion procedures, while the diffusion architecture confuses the image matrix in a bilateral direction with ultra-low power consumption. The proposed system achieves preferable number of pixel change rate (NPCR) and unified average changing intensity (UACI) of 99.61% and 33.46%, and a lower encryption time of 3.30 seconds, which performs better than some current image encryption algorithms. The simulated results and security analysis demonstrate that the proposed mechanism can resist various potential attacks with comparatively low computational time consumption.

Since technological innovation, adoption, and diffusion is a fundamental engine for a company's competitiveness and in turn a nation's industrial development, diffusion of technological innovation has been one of popular research themes to many researchers and scholars for decades. Especially, in today's knowledge-based economy, the IT technology became a fundamental infrastructure for a nation and thus their impact on a nation's economy has grown to be tremendous. This paper investigates the patterns of technological diffusion of 16 telecommunications services. Firstly, we identify the optimal diffusion model which represents the 15 IT innovation best in terms of goodness-of-fit. Secondly, based on the best model identified we cluster the 16 IT innovations according to their diffusion characteristics such as penetration rate and diffusion speed. Lastly, we categorize the innovations in terms of technology (voice-based innovation and data-based innovation) and demand (household-use and business-use) attributes, and compare their diffusion patterns and found some meaningful difference in diffusion patterns. We hope the result helpful to corporate managers as well as policy makers in relevant areas.
