Research and innovation are widely agreed to be major driving forces behind long-term productivity and economic growth. However, the relationships have proven to be difficult to quantify. We make reference to the international literature and draw on recent research for Australia to advance our understanding of these relationships. Particular focus is on assessing the impact of publically financed R&D on productivity. The conclusions have implications for government innovation policies, providing insight into possible productivity gains from funding reallocations. Specifically, the findings suggest that government research agencies and higher education are areas in which investment leads to more potential productivity gains.

Standards impact the economy in various ways. Moreover, intense competition exists between a variety of standards in this era of globalization. This paper quantifies the economic effect of multiple standards in the Information Communications and Technology (ICT) sector. Thus, it identifies and specifies which standard applies when economic gains exist. A model is developed which quantifies the magnitude of the economic effect of multiple standards as compared with a single standard or no standard. The model allows for both the micro- and macroeconomic gains from standardization to be quantified. Preliminary estimates indicate that at the macro level the multiple standards multiplier is approximately three. That is for every dollar invested, the gain is on the order of three dollars. Although not as robust. preliminary results indicated a similar economic gain at the micro level Overall, multiple standards dominate a single standard. This paper applies the model to IMT-2000, an example of multiple standards, to demonstrate this approach to quantify the standards economic effect.

The collaboration among academia, industry, and public research sector gains importance in these days. This is essential for implement competent regional and national innovation systems. There have been many governmental programs for activating collaboration among innovation actors. Most policy programs for collaboration have aimed at increasing S&T and innovation potential and constructing S&T infrastructure. However, Korea has not produced a sufficient level of collaboration, especially on regional level. Most policy programs could not reach regions and many regions have no enough innovation actors. In order to activate R&D collaboration, therefore, we suggest that Korean S&T community should build and implement "collaborative research centers" all over the regions. This concept is very new approach, especially because it focuses on collaboration among regional innovation actors. In this paper, we discuss a concept, type, and execution strategy of collaboration research centers. We expect that these centers will play an important role in implementing successful regional innovation systems, as they will link regional innovation actors very closely.

In this paper, we have performed a study that modifies the CPW Pad configurations to improve an $f_{max}$ characteristic of metamorphic HEMT. To analyze the CPW Pad structures of MHEMT, we use the ADS momentum simulator developed by $Agilent^{TM}$. Comparing the employed structure (G/W = 40/100 m), the optimized structure (G/W = 20/25 m) of CPW MHEMT shows the increased $S_{21}$ by 2.5 dB, which is one of the dominant parameters influencing the $f_{max}$ of MHEMT. To compare the performances of optimized MHEMT with the employed MHEMT, DC and RF characteristics of the fabricated MHEMT were measured. In the case of optimized CPW MHEMT, the measured saturated drain current density and transconductance $(g_m)$ were 693 mA/mm and 647 mS/mm, respectively. RF measurements were performed in a frequency range of $0.1{\sim}110$ GHz. A high $S_{21}$ gain of 5.5 dB is shown at a millimeter-wave frequency of 110 GHz. Two kinds of RF gains, $h_{21}$ and maximum available gain (MAG), versus the frequency, and a cut-off frequency ($f_t$) of ${\sim}154$ GHz and a maximum frequency of oscillation ($f_{max}$) of ${\sim}358$ GHz are obtained, respectively, from the extrapolation of the RF gains for a device biased at a peak transconductance. An optimized CPW MHEMT structure is one of the first reports among fabricated 0.1 m gate length MHEMTs.

Policy planners in Asia readily covet high technology districts and regional systems of innovation such as Silicon Valley. We examine the law's role, by way of covenants not to compete (競業禁止條項) in the development of Silicon Valley by reviewing the literature from 1999 through 2013. The research suggests that in certain high-tech districts such as Silicon Valley, there are greater gains in the innovation of a region by prohibiting CNCs. While we emphasize CNC law as the main legal determinant to Silicon Valley's success, the application of trade secret law and the inevitable disclosure doctrine are also factors that can aid or restrict the mobility and knowledge spillover of a region. Even with much explored, perspectives are lacking from a regional innovation systems analysis, and more so in the context of Asian nations. To tackle these gaps, three analytical frameworks are presented that entails labor law, law and economics, and law and innovation. And from within the law and innovation framework, research is introduced in the hope that future discussions on Asian regional innovation systems consider the legal foundation of Silicon Valley.

Digital technology has been changing everyday life of ordinary people let alone the structure of world industry. The elderly care service is also going through changes influenced by the unavoidable impact from torrents of digital technologies. There are numerous reports and news about the digital technologies increasing the efficiency and effectiveness of care service yet lacking systematic understanding of the sources of such improvement. This study aims to present a new classification framework for digital elderly care service innovation to fully utilize the power of digital technologies drawing on insights from innovation studies and service studies. First, 4 features of digital technologies are identified as sources of new value in service innovation. The co-creation of value by users and producers in service and technology development is discussed to illuminate users' contributions to service innovation. Communication of needs and ideas with producers and application of new technologies into everyday practice of life are identified as the source of new value which can be attributed to the elderly. Customization along with efficiency gains is the key to digital elderly care service innovation. The classification framework, thus, incorporates the needs of the elderly as one axis of criteria in the conventional technology-centered framework. The new classification framework would help give due weight to user-driven or demand-driven innovation in the elderly care service R&D activities.

This present study investigatesed the impact of the team innovation-oriented human resource management (HRM) practices on employees' turnover intention among financial, pharmaceuticals, distribution, and manufacturing industries in Korea. Furthermore, we explored whether risk perception of turnover and the cost of changing job would mediate the relationship between team innovation-oriented human resource management practices with employees' turnover intention in different industries in Korea. To that end, PLS structural equation modeling was used to exam the research hypothesis. We have found that team innovation-oriented HRM practices have a significant impact on employees' turnover intention. Moreover, we have discovered risk perception of turnover and the switching cost of changing job playing mediating role in the relationship of team innovation-oriented HRM practices with turnover intention among different type of industries employee. Lastly, the theoretical implications were discussed based on these findings.

본 연구에서는 혁신도시지역과 그 주변지역의 지가 데이터를 바탕으로 혁신도시사업에 따라 토지가격이 어느 시점부터 어느 정도 변동했는지 살펴보았고, 이를 통해 현행 제도가 개발이익의 배제원칙에 잘 부합하지 않음을 밝히는 한편, 현행 제도를 개발이익의 배제원칙에 보다 부합하도록 개선하기 위한 방안들을 모색하였다. 우선 혁신도시지역과 그 주변지역의 지가 데이터를 분석해 보면, 대부분의 혁신도시지역의 지가가 2005년부터 그 주변지역들에 비해 통계적으로 유의하게 상승하기 시작하였음을 알 수 있다. 즉, 이 시기부터 혁신도시사업과 관련한 정보가 지가에 반영되기 시작하였다고 볼 수 있는데, 이와 같이 혁신도시사업 관련 정보가 반영된 지가를 바탕으로 실제 보상액을 산정하면 개발이익의 배제원칙과는 괴리가 생기게 된다. 그러나 토지보상법 제70조에 따른 보상액 산정의 기준지가는 2007년 1월 1일 공시된 공시지가이며, 또한 실제로도 이러한 기준을 적용하여 보상이 진행되었다. 즉, 2005년부터 2006년 말까지 개발 정보가 해당 혁신도시 지가에 반영되었음에도 불구하고 이를 배제하기 위한 제도적 장치 및 노력 없이 보상이 진행되었다. 이러한 문제들을 해결하기 위해 본 연구에서는 크게 두 가지 방안을 제안하고 있다. 첫째, 토지보상법 제70조 제5항에서 소급적용할 수 있는 공시지가의 한계를 두지 말고, 대신 개발이익이 반영되지 않았다고 판단되는 가장 최근의 공시지가를 기준시가로 적용하도록 변경하는 것이 필요하다고 판단된다. 이렇게 정해진 기준시가를 바탕으로 가격인정시점까지의 통상적인 평균 물가상승률, 평균 지가상승률 등을 바탕으로 보상액을 보정한다면 개발이익 배제의 원칙에 보다 부합할 것이다. 둘째, 개발이익이 지가에 반영되었다고 판단하는 기준을 하위 법령에 명시적으로 포함시킬 필요가 있다. 현행 제도하에서는 수용보상액 산정 시 개발이익 반영 여부에 대한 평가자의 자의적인 해석이 포함될 가능성이 크다. 따라서 본 연구에서의 학술적 연구 결과와 현행 토지보상평가지침(감정평가협회) 등의 기준 등을 참고하여 개발이익 반영 여부를 판단하는 기준을 개선할 필요가 있다.
