기술혁신지향성의 개념이 이론적으로나 실무적으로 중요한 가치를 지니고 있음에도 불구하고, 기존의 연구에서는 기술혁신지향성에 관한 개념이 제대로 정립되어있지 않고 또한 이에 대한 적합한 변수측정이 이루어지지 않고 있다. 그러한 기술혁신지향성에 대한 기존 연구의 결함을 인지하여, 본 연구에서는 기술혁신지향성의 개념을 정립하고 그 정립된 개념을 적합하게 포착하는 새로운 측정도구를 제시하였다. 보다 구체적으로, 본 연구에서는 기술혁신지향성을 기술선도 지향성(proclivity to technological leadership)과 기술혁신 개방성(openness to technological innovation)의 두 요인으로 구성된 것으로 개념화하고 그 두 요인으로 구성된 기술혁신지향성의 개념을 변수조작화하기 위한 새로운 측정도구를 제시하였다. 본 연구에서는 새로이 제시된 기술혁신지향성의 측정도구의 신뢰성과 타당성을 검증하였고 또한 그러한 기술혁신지향성의 측정치를 기반으로 기술혁신지향성과 기업성과 사이의 관계를 실증 분석하였다. 97개의 국내 IT중소기업을 대상으로 분석한 결과, 제안된 기술혁신 지향성의 측정도구는 높은 신뢰성과 타당성을 갖는 것으로 나타났다. 또한 분석 결과 기술혁신지향성이 기업의 기술혁신성과와 긍정적인 관계를 갖고 기술혁신성과가 기술혁신지향성과 재무성과 사이의 관계를 매개하는 역할을 하는 것으로 나타났다.

Social enterprises pursue innovation to create socio-economic impact for the marginalized communities. The founders of social enterprises drive goal-oriented innovation, whereas, interactions with ecosystem is crucial to create and diffuse innovation. However, studies are scant on creation as well as diffusion of innovation emerging from social enterprises. This paper attempts to understand innovation emerging from social enterprises through an exploration of innovation focus, interactions with ecosystem, and measurement of innovation performance. A cross-sectional study is performed to understand the relationship between founders' orientation and innovation performance, and the mediating role of innovation focus and ecosystem interactions. A cluster sampling across four states in India - Karnataka, Telangana, Maharastra and Tamil Nadu - resulted in participation from 207 social enterprises. The results of partial least squared structural equation modeling (PLS-SEM) demonstrate the positive complementary mediating role of innovation focus in the relationship between founders' orientation and innovation performance. Moreover, this paper illustrates that founders' persistent focus on innovation creates positive results for social enterprises as well as beneficiaries.

An integration system with multi-measurement sets can be realized via combined application of a centralized and federated Kalman filter. It is difficult for the centralized Kalman filter to remove a failed sensor in comparison with the federated Kalman filter. All varieties of Kalman filters monitor innovation sequence (residual) for detection and isolation of a failed sensor. The innovation sequence, which is selected as an indicator of real time estimation error plays an important role in adaptive mechanism design. In this study, the centralized Kalman filter with adaptive measurement fusion is introduced by means of innovation sequence. The objectives of adaptive measurement fusion are automatic isolation and recovery of some sensor failures as well as inherent monitoring capability. The proposed adaptive filter is applied to the GPS/SDINS integration system with an additional sensor. Simulation studies attest that the proposed adaptive scheme is effective for isolation and recovery of immediate sensor failures.

In this paper, we developed a temperature measurement system based on an infrared temperature imaging module for thermal safety verification of a plasma skin treatment device (PSTD). We tested a pilot product of the low-temperature PSTD using the system, and the temperature increase of each plasma torch was well-monitored in real-time. Additionally, through the approximation of the temperature increase of the plasma torches, a certain limitation of the plasma treatment time on skin was established with the International Electrotechnical Commission (IEC) guideline. We determined an appropriate plasma treatment time ($T_{Safe}$ < 24 minutes) using the configured temperature measurement system. We believe that the temperature measurement system has a potential to be employed for testing thermal safety and suitability of various medical devices and industrial instruments.

One of primary assumptions on DEA is that all DMUs for evaluation should be homogeneous. In comparative analysis among DMUs with relative efficiency measurement, it should be evaluated under identical conditions by ruling out external environmental influences. In this study, a measurement of innovation efficiency using the three-stage approach is performed. The approach employs DEA to measure relative efficiency and Tobit regressions to control external variables affecting innovation activity. The approach applied to firms in Korean Innovation Survey: Service Sector 2003 and 2006. Final efficiency scores of the approach represent net efficiency of the innovation. This study found that there is a increasing on technical efficiency of third stage, and it has difference with first stage significantly. Besides, a decrease on standard deviation of third stage is found. It means DMUs biased lower due to unfavorable condition and ones biased higher due to favorable condition are fallen into an identical operating environment through the approach. A measurement of net efficiency, excluding external effects, ensures the homogeneity of DMUs so that improves the reliability in terms of its analysis results. This study is expected to provide a direction and to be a valuable reference to further evaluation of innovation performance in Korean service sector.

This is a paper to understand the economic effects of the measurement standards by translog cost function. The data, as of the end of 1998, are from a survey of 514 firms in Korean industry. The analysis is compared to that of 1992 data analysis to check the trend. There are a little differences on the estimated coefficients, but there is no basic difference on trend of economic effects. The Investment on measurement standards have been contributed positively on the major managerial indicators such as productivity, profit, and so on.

창의성, 기업가정신, 기술혁신 지향성향 등은 기술혁신을 실현하기 위한 핵심적인 요인이다. 기업의 기술혁신을 주도하는 주체는 경영자이다. 햄브릭 교수의 고위층 이론(Upper Echelons Theory)에 따라 경영자 개인수준의 창의성이 조직의 기술혁신체계 내에 다양한 양상으로 투입될 것이고, 조직의 기술혁신체계가 경영자의 창의성에 긍정적인 영향을 받아 기업가지향성과 기술혁신지향성을 발현함으로써 혁신성과를 높일 것이다. 본 연구에서는 국내 반도체분야 기업 중 연구조직을 보유한 132개 기업의 경영자의 개인창의성이 연구조직의 기업가지향성, 기술혁신지향성을 매개로 기업의 혁신성과에 영향을 주는지 살펴보기 위하여 구조방정식으로 분석하였다. 이를 위해, 선행 연구 문헌에서 확인한 개인창의성, 기업가지향성, 기술혁신지향성 등을 측정 요소로 적용하였다. 구조방정식 분석 결과, 경영자의 개인 창의성이 연구조직의 기업가지향성과 기술혁신지향성을 매개로 할 때 기업의 혁신성과에 매우 유의미한 양(+)의 관계를 보였고, 경영자 창의성의 혁신성과와 직접적인 효과는 통계적으로 유의하지 않은 것으로 나타났다. 결국, 기술혁신을 주도하는 경영자의 개인창의성과 연구조직의 기업가 지향성과 기술혁신지향성은 기업의 성공적 혁신성과 창출을 위해 매우 중요한 요인임을 말해주고 있다.

For a battery module where single cells are connected in series, the single cells should each have a similar state of charge (SOC) to prevent them from being exposed to an overcharge or over-discharge during charge-discharge cycling. To detect the existence of unbalanced SOC cells in a battery module, we propose a simple measurement method using a single-frequency response of electrochemical impedance spectroscopy (EIS). For a commercially available graphite/nickel-cobalt-aluminum-oxide lithium-ion cell, the cell impedance increases significantly below SOC20%, while the impedance in the medium SOC region (SOC20%-SOC80%) remains low with only minor changes. This impedance behavior is mostly due to the elementary processes of cathode reactions in the cell. Among the impedance values (Z, Z', Z"), the imaginary component of Z" regarding cathode reactions changes heavily as a function of SOC, in particular, when the EIS measurement is performed around 0.1 Hz. Thanks to the significant difference in the time constant of cathode reactions between ≤SOC10% and ≥SOC20%, a single-frequency EIS measurement enlarges the difference in impedance between balanced and unbalanced cells in the module and facilitates an ~80% improvement in the detection signal compared to results with conventional EIS measurements.
