With an explosive growth of internet and a change of consumer's demand, Post PC is emerging as a substitute for the existing desktop computer and laptop computer. Post PC is a new computer which is portable with wireless networking, cheaper than the existing PCs and specialized in the specific function that consumers want. Furthermore, the shape and the ability of Post PC are dependent on its specific function. The rudimentary Post PCs such as PDA, web-pad and smart-phone are already usable. And in the future, owing to the progress of technologies, the heterogeneity of relate companies and the low entry barrier, various Post PCs will be developed. In this paper, we analyze consumers' willingness-to-pay for Post PC with the attributes such as the portability, the speed of CPU, the data input method (using key board, or notepad etc), the size of monitor and price. To estimating consumers' willingness-to-pay for the attributes of Post PC, we apply a contingent ranking method, which makes the respondents rank hypothetical Post the portability, the speed of CPU, the data input method (using key board, or notepad etc),the size of monitor and price. To estimating consumers' willingness-to-pay for the attributes of Post PC, we apply a contingent ranking method, which makes the respondents rank hypothetical Post PC alternatives featuring various combinations of attributes, to a survey data collected in Korea. Using the estimated willingness-to-pay, we predict the shape and the ability of future's Post PC and draw policy implications for the national and company level R&D strategies.

Resveratrol, a polyphenolic compound with antioxidative property, was purified from the grape's twig to be used as functional additives of food and/or cosmetics. Extraction of the grape's twig was performed using 80% ethanol in ultrasonic extractor for 60 min. The crude extract was purified up to 99% after elution through silica gel open column chromatography. The stability of the purified resveratrol was as follows: a half life of 90 days at 40$^{\circ}C$ and 60 days at 25$^{\circ}C$. A sensory test of the commercial grape juice including the 1-10 ppm of purified resveratrol showed better preference than the grape juice without purified resveratrol additive. Color and smell test showed no difference between the samples. The grape twig can be used as a valuable resource for the extraction of resveratrol, which would be added to nutraceutical and cosmetic products.

Technology standard continues to exist as an social agreement throughout all industry. With development of Information and Communication, it is recently considered as a strategic factor for enhancing interoperability and increasing market dominance. Hence, technology standard research(standardization research) have a significance in analyzing the process of standard adoption and its economic effect and deriving theoretical and policy implications. However, as existing relative researches are lack in consideration on indigenous value of technology and its interoperability, there exists limitation in drawing the result of technology centered analysis. The goal of this study is to suggest new technology centered standard method by implying function of technology differentiation rate and technology preference that are deduced by technology network analysis into two stage game theory. As an example of empirical case, we selected wireless pan technology of Internet of Things, and derive its technological structure and implications related to standard.

Although a existing consumer market have been studied in depth in the new technology product market, the market research on the overall level of value chain to consist of consumers, distributors, and manufacturers is weak. Therefore, in this paper consumers' purchase of new technology products were simulated and analyzed by a consumer selection model and a multi-agent model, which consist of consumers, distributors and manufacturers. Our research was focused on customer preference study in new technology product market by using conjoint analysis and discrete choice model. And changes in consumer behavior based on adoption of new technologies and offering of incentives were analyzed by ABM (Agent-based Model). In conclusion, the market share of technology products was risen when provision of incentives corresponding to inventory level and demand for new technology products occurred at the same time.

This study empirically examined the career orientations of researchers who worked for government-sponsored research institutes. Specifically, we considered the individual level's variables of age, project, and organization characteristics as the influential factors of researchers' career orientations and then investigated the relationship between career orientation and work attitudes. The results, based on the survey about 373 researchers, showed that both project career orientation and technical transfer career orientation were higher as grade level or age was higher. Moreover, the preference of career orientation was changed according to the mission of institute and the project type. Finally, the study suggested some practical implications on career development management for government-sponsored research institutes and discussed the limitations and the further research directions on career development of researchers.

최근 이동통신기술이 급속히 발달함에 따라 국내는 물론 전세계 이동통신업계는 제 3세대 이동통신서비스의 성공여부에 많은 관심을 쏟고 있다. 지금까지의 이동통신산업의 성장이 빠른 기술개발에 의존한 기술추동적(technology-push) 성격을 지녔다면, 이동통신시장이 포화상태에 근접하고 있는 최근에는 서비스 및 장비 양면에서의 경쟁이 치열해 짐으로써 소비자의 기술에 대한 선택이 더욱 중요해짐에 따라 수요견인적(demand-pull) 기술혁신이 예상된다. 따라서, 이동통신서비스의 확대에 따른 특정기술에 대한 소비자의 선호에 대한 올바른 판단이 향후 산업의 기술진화방향을 예측하는데 핵심적인 역할을 할 것으로 생각된다. 현재 이동통신기술의 진보의 키워드는 '멀티미디어화'이다 향후 VOD (Video On Demand) 등 비디오 스트리밍(video streaming) 기술을 이용한 동영상 서비스, 화상전화, 타 디지털기기(예를 들어 PDA, 디지털 카메라 등)와의 융합 등의 서비스가 본격화되고 차세대 이동통신망의 구축이 가시화됨에 따라 이동통신의 멀티미디어 기능은 더욱 주목받게 될 것이다. 따라서 이동전화 단말기 창의 컬러화는 이러한 이동통신기술의 새로운 패러다임을 떠받치고 있는 가장 중요한 이정표로서의 의미를 지니고 있다. 본 연구에서는 표시1창의 컬러화로 실현되는 기술혁신요소에 대해서 소비자가 부여하는 가치를 분석하고자 한다. 하지만, 컬러 단말기의 보급이 초기단계에 머무르고 있는 연구시점의 특성상 현시자료가 가용하지 않았기 때문에, 소비자에게 가상의 품질특성을 지닌 제품 조합을 제시하고 이에 대해 소비자가 순위를 매기게 함으로써 소비자의 선호를 측정하는 컨조인트(conjoint) 방법론을 사용하였으며, 소비자의 진술선호(stated preference)에 기초하여 이동통신단말기의 개별 특성에 대한 부분가치와 보상잉여를 측정하였다. 또한, 이를 통해 창의 컬러화로 인해 기대되는 초과이윤의 가능성 등 경제적인 효과들을 정량적으로 분석하고, 브랜드 가치 등 기존의 단말기 경쟁력 요소들과의 비교를 통하여 컬러화가 가져다 줄 경쟁요소들을 추정함으로서, 기술확산 메커니즘을 확인하고자 한다.
