The main objective of this research is to examine the spillover effects of technological knowledge from IT industry to other industrial sectors and, based on empirical findings, to draw policy implications and suggest policy directions. To this end, we divide IT industry into IT equipment and IT service, assuming that these two sub-sectors are considerably different each other in terms of technology knowledge flow. Other industries are classified into 17 different sectors based on the KSIC of 1990. As the proxy measure of technological knowledge, the notion of R&D stock is employed. The Input/output(I/O) Table is used to define the inter-industrial flow pattern and to draw the knowledge flow matrix. As the research methodology, cost function model is employed to gauge the spillover effects of technological knowledge of IT industry. Based on the results of analysis, it is found that the economic impact of technology diffusion also exhibits a different pattern between IT equipment and IT service. The diffusion of IT equipment tends to show labor-substitution effect whereas IT service displays labor-creation effect. This fact should be considered in devising industry, education, and labor policy. The expectations from this research are as follows. First, the sectoral pattern, difference between IT equipment and service in particular, identified from this research may shed light on the sector-specific policy direction. It is emphasized that a sector-specific approach, rather than an aggregate approach, is relevant for formulating IT policy. Second, it is expected that the importance of technology diffusion programs and policy measures are recognized among policy makers in IT industry.

The rise of crowdsourcing and web 2.0 opens plenty of opportunities for companies who want to exploit external sources of ideas for internal innovation. Utilization of crowdsourcing for product design and development has been attracting the attention of both enterprises and researchers. Many cases of implementation of crowdsourcing for product design and development such as: Threadless, FIAT Mio, Lego online Factory, etc., have made crowdsourcing a promising alternative source of innovative power. Although crowdsourcing gained access due to improved Internet access and web 2.0, it is little understood how the crowd, with respect to participation, behaves for any crowdsourcing project. To investigate this, we conducted an experiment on a real crowd of engineering related individuals to figure out the crowd participation pattern for various product design and development phases of a new product development project. The experiment results give a quantitative view of the participation of the crowd (i.e., crowd participation pattern) in various phases of a product design and development process that utilizes crowdsourcing, provide a practical guidance for companies to harness the power of the crowd sensibly, and provide experimental data for further research in this field.

본 연구는 공간적 자기상관(spatial autocorrelation) 정도를 측정하는 공간통계 기법인 MORAN I를 사용하여 산업집적의 공간적 패턴과 구조를 분석하였다. 분석결과 우리나라는 수도권 이외 지역의 혁신환경이 열악한 가운데 주요 산업집적지가 수도권 일대와 동남권 일대를 중심으로 분포하고 있는 다핵형 공간구조를 형성하고 있다. 그리고 일부 산업의 경우 산업집적지는 광역 시 $\cdot$ 도 단위의 행정구역을 넘어서는 집적패턴이 나타나고 있다. 이에 따라 본 연구는 한국경제발전을 위한 최우선 과제의 하나가 산업집적과 혁신환경의 공간적 불일치라는 경제 공간구조를 조정하는 것이어야 하며, 이를 위해서는 16개 광역 시 $\cdot$ 도 보다는 인접한 2$\∼$3개 광역 시 $\cdot$ 도를 포괄하는 경제권역을 단위로 산업클러스터 기반의 지역혁신체제 구축이 필요함을 제시하였다.

This study examines market acceptance for DMB service, one of the touted new business models in Korea's next-generation mobile communications service market, using adoption end diffusion of innovation as the theoretical framework. Market acceptance for DMB service was assessed by predicting the demand for the service using the Bass model, and the demand variability over time was then analyzed by integrating the innovation adoption model proposed by Rogers (2003). In our estimation of the Bass model, we derived the coefficient of innovation and coefficient of imitation, using actual diffusion data from the mobile telephone service market. The maximum number of subscribers was estimated based on the result of a survey on satellite DMB service. Furthermore, to test the difference in diffusion pattern between mobile phone service and satellite DMB service, we reorganized the demand data along the diffusion timeline according to Rogers' innovation adoption model, using the responses by survey subjects concerning their respective projected time of adoption. The comparison of the two demand prediction models revealed that diffusion for both took place forming a classical S-curve. Concerning variability in demand for DMB service, our findings, much in agreement with Rogers' view, indicated that demand was highly variable over time and depending on the adopter group. In distinguishing adopters into different groups by time of adoption of innovation, we found that income and lifestyle (opinion leadership, novelty seeking tendency and independent decision-making) were variables with measurable impact. Among the managerial variables, price of reception device, contents type, subscription fees were the variables resulting in statistically significant differences. This study, as an attempt to measure the market acceptance for satellite DMB service, a leading next-generation mobile communications service product, stands out from related studies in that it estimates the nature and level of acceptance for specific customer categories, using theories of innovation adoption and diffusion and based on the result of a survey conducted through one-to-one interviews. The authors of this paper believe that the theoretical framework elaborated in this study and its findings can be fruitfully reused in future attempts to predict demand for new mobile communications service products.

Swietenia mahagoni is one of the commercial timbers in Indonesia. Mahogany heartwood is an important characteristic as it relates to the natural durability and aesthetics of the wood. Lipophilic extractives are known to be involved in the heartwood formation process. Therefore, this study aims to determine the lipophilic compounds associated with heartwood formation. The n-hexane extract from sapwood and heartwood samples (1 to 5 years) was analyzed by gas chromatography-mass spectrometry. The results showed that the content of n-hexane extract ranged from 0.76% to 2.45% based on dry wood. The main group of compounds identified in the lipophilic fraction consisted of sterols (β-sitosterol, stigmasterol, campasterol, and cyclolaudenol), fatty acids (palmitic, oleic, linoleic, and stearic acid), and hydrocarbons (pentadecane, 1-octadecane, hexadecane, cyclotetracosane, cycloeicosane, and cyclooctacosane) after heartwood formation. In addition, the hydrocarbon fraction was the largest, followed by sterols, fatty acids, and 1-heneicosanol. In the radial variation, the distribution of fatty acids was greater in the sapwood than in the heartwood (4-year-old). However, the reverse pattern was found at the age of 5 years. The lipophilic fraction was generally more abundant in the heartwood compared to the sapwood, especially at 5 years of age, with much higher levels than when the heartwood was forming (4 years). These findings show that when the heartwood formation begins, the lipid composition was not fully metabolized at the beginning of heartwood formation compared to 5-year-old trees.

Purpose - The goals of this study are the following. First, this study focused on customer satisfaction of in-flight service. Specifically, in-flight duty free items were considered because of their potential value related with the differentiated strategy of airline companies. Second, this study analyzed feasible strategies that would fence off the aversive attitudes of consumers toward innovation regarding in-flight duty free items. Third, this study strived to discover implicit routes related with the reactions of of consumers to innovation. Fourth, the construal level theory was applied to the context of in-flight service. Psychological distance is expected to promote acceptance of innovation for duty free items. Research design, data, and methodology - This study consisted of three experiments. All data were collected through the participation of university students. First, the experiment employed a 2×2 between-subject design. The first independent variable was temporal distance (long vs. short of navigation time). The second independent variable was innovativeness (innovative duty free items vs. typical items). Further, experiment 2 involved a 2×2 between-subject design. The first independent variable was social distance (typical vs. atypical stewardess image). The second was innovativeness that was based on a pattern similar to that of the prior experiment. The third experiment involved a 2×2×2 design. The first and second independent variables were temporal distance and item innovation, respectively, based on the method of experiment 1. The third independent variable was cognitive depletion (depletion vs. control condition). Results - Experiment 1 demonstrated that the innovation of duty free items would need to consider the journey time of the airline. Specifically, innovative items were preferred in case of a long journey; typical items, however, were liked in a short journey. Further, experiment 2 demonstrated that, in spite of a short journey, innovative items would be preferred if an atypical stewardess was serving. An atypical stewardess was linked with social distance, and the psychological effects would activate a creative and flexible mindset that would fit with innovative duty free items. The final experiment was accomplished for the examination of cognitive processing of psychological distance on innovation-acceptance. Specifically, if the effects were related with systematic processing, then cognitive effort would be needed. In contrast, if they were related with heuristic processing, then such efforts would not be required. The same pattern appeared under both cognitive depletion and control condition; therefore, the effects of psychological distance were implied to be heuristic processing. Conclusions - Managers need to consider the navigation time, stewardess concepts, and depletion of consumers as important factors for innovative strategy regarding in-flight service. Longer journeys are more successful for innovative trials. Further, a more atypical stewardess image is more successful for atypical service. Long navigation and unfamiliar stewardesses may activate creative and flexible thinking. Further, cognitive depletion of consumers is not a dominant factor of psychological distance effects, because the effects are not related with systematic processing, but with heuristic processing.

그간 진화경제학적 관점에서 산업 고유의 특성에 따라 발생하는 기술혁신 패턴을 고찰하고자 하는 시도가 있어왔다. 본 연구는 국내 제조업을 기술집약도에 따라 고기술산업과 저기술산업으로 구분하고 제품혁신 패턴 및 혁신 성과 결정요인의 산업별 차이를 확인하였다. 기존 연구들은 연구개발 수행에 대한 기업의 의사결정 과정에서 연구개발을 수행하도록 만드는 결정요인을 분석에 반영하지 못했다는 지적이 있다. 본 연구에서는 이러한 문제를 극복하기 위해서 Heckman 표본선택모형과 허들모형을 대안으로 제시하고, "2014년 중소기업기술통계조사" 자료의 1,637개 기업에 대해 분석을 실시했다. 분석 결과 제조업의 중소기업이 수행하는 제품혁신 패턴과 제품혁신 성과에 영향을 미치는 결정요인들에 있어 고기술산업과 저기술산업 간 뚜렷한 차이가 있다는 것을 확인 할 수 있었다. 또한, 기존 연구의 한계점을 극복하기 위해 채택한 연구모형의 확장을 통해서 중소기업 연구개발 수행에 대한 의사결정 과정에서 표본선택편의 문제와 허들로 표현되는 문지방이 있다는 것을 발견할 수 있었다. 본 연구는 산업별 제품혁신 패턴의 특징과 제품혁신 성과 결정요인을 다각적으로 살펴보았고, 중소기업의 연구개발 수행에 대한 의사결정 과정을 더 깊이 이해할 수 있었다는 점에서 학술적 의의가 있다.

서비스와 기술 간 융합 현상이 가속화되고 있는 비즈니스 환경 속에서 서비스 혁신 활동을 간명하게 파악하고 이들 간의 관계에 대한 직관을 얻을 수 있는 새로운 패턴분류체계의 필요성이 증대하고 있다. 본 연구는 서비스의 상호연관 되고 다차원적인 특성을 고려하여, 퍼지셋 질적 비교분석 방법을 채택하여 서비스 혁신 패턴을 분석하고자 한다. 이를 위해 본 연구는 기존 연구를 기반으로 4개의 서비스 혁신 차원(i.e., 서비스 창출, 서비스 전달, 고객 상호작용, 그리고 기술)과 서비스 혁신 환경(기업 규모) 등 5개의 원인 변수들을 도출하고 기업 성과(매출성장률)를 결과 변수로 두고 분석을 시도하였다. 국내의 198개의 지식 서비스 기업들을 대상으로 데이터가 수집되었으며, 이를 기반으로 분석한 결과 높은 기업 성과를 보이는 4개의 서비스 혁신 패턴과 낮은 기업 성과를 보이는 4개의 서비스 혁신 패턴이 도출되었다. 연구결과를 종합하면 다음과 같다. 고객 상호작용 혁신은 높은 기업성과에 유의한 영향을 미치는 가장 중요한 핵심 조건이나, 단독으로 수행되기보다 기술 혁신이나 서비스 전달 혁신 활동과 상호작용을 하였을 경우 높은 기업성과를 보였다. 기술 혁신은 비기술 혁신(i.e., 서비스 창출, 서비스 전달, 고객 상호작용)과 결합하였을 경우 높은 기업성과를 가져오는 서비스 혁신의 핵심 활동인 것으로 나타났으나, 이 경우 결합되는 하나 이상의 비기술 혁신 활동이 핵심 조건으로 수행되어야만 기업성과에 유의한 영향을 미치는 것으로 나타났다. 기업혁신은 서비스 혁신에서 단독으로 수행될 경우 오히려 낮은 기업성과를 가져왔다. 서비스 창출 혁신과 서비스 전달 혁신은 기술 혁신과 모두 핵심 조건으로 결합되어 수행되었을 때 높은 기업성과를 보였다.
