Iota carrageenan-containing surimi was refrigerated for 7 days to investigate the change in its properties. Physical properties, color differences, and sensory evaluation were tested for analysis after addition of 0–3 Wt% iota carrageenan. In unheated surimi, the 2% carrageenan- containing surimi had higher chromaticity and color difference compared to the surimi without added carrageenan. However, the surimi with 3% iota carrageenan showed enhanced yellowness, resulting in a modified color difference. Surimi containing iota carrageenan showed the same trend in color difference in heated surimi after storage for 7 days, particularly when carrageenan content was 2% or greater. The hardness, gumminess, and chewiness of the heated Iota carrageenan-containing surimi also increased after 7 days of storage. Compared to surimi without added carrageenan, the heated Iota carrageenan-containing surimi had higher hardness, gumminess, chewiness, and lower adhesiveness after storage. The overall preference for surimi decreased, while the hardness increased, when carrageenan was added. Therefore, the addition of the iota carrageenan to stored surimi can significantly enhance its hardness.

In this paper, we report computational testing result to examine the validity of firm’s bankruptcy risk estimation through quantification of supply chain risk. Supply chain risk in this study refers to upstream supply risk and downstream demand risk, To assess the firm’s risk affected by supply chain risk, we adopt unit of analysis as industry level, since supply and demand relationships of the firm could be generalized by the industry input-output table and the availability of various valid economic indicators which are chronologically calculated. The research model to estimate firm’s risk level is the linear regression model to assess the industry bankruptcy risk estimation of the focal firm’s industry with the independent variables which could quantitatively reflect demand and supply risk of the industry. The publicly announced macro economic indicators are selected as the candidate independent variables and validated through empirical testing. To validate our approach, in this paper, we confined our research scope to steel industry sector and its related industry sectors, and implemented the research model. The empirical testing results provide useful insights to further refine the research model as the valid forecasing mechanism to capture firm’s future risk estimation more accurately by adopting supply chain industry risk aspect, in conjunction with firm’s financial and other managerial factors.

옴니채널의 상대적 이점에 기여하는 채널 통합 요인 탐색

한현수,임동수,강태욱 한국기술혁신학회 2022 기술혁신학회지 Vol.25 No.2

Omni Channel has become a major trend, which is literally defined as integrating online, offline, and mobile channels across all the consumer buying processes of search, purchase, and after service. In this study, we intend to formalize the term ‘integration’ in the sense of being distinguished from multi-channel, or on-off hybrid channels. We draw upon transaction cost economic theory to extract the integration constructs which, through reduction of purchase transaction time and risk, contribute to the relative advantage of omni-channel. Subsequently, the research model is developed with the first-order constructs of information concurrency and price consistency as the constituents of transaction time reduction, and the other two first-order constructs of information extensibility and service consistency as the constituents of transaction risk reduction. Accordingly, research hypotheses are formed, and survey-based empirical testing is conducted using PLS. The statistical testing result validates the research model and offers useful insights for industrial applications and further research on IT-based omni-channel. 정보통신 기술 발전으로 온라인과 오프라인, 모바일 채널 등의 통합을 추구하는 옴니채널 환경은 구매자의 탐색, 구 매, 그리고 사후 서비스 등 구매 프로세스 전반에 걸친 다양한 채널의 이음새 없는 통합으로 정의된다. 본 논문에서는 이와 같은 구매 프로세스 전반에 걸친 통합이 기존의 하이브리드 채널과 차별적으로 구매자에 상대적 이점에 기여하 는 통합 요인을 정형화하고자 하였다. 이를 위하여 거래비용경제 이론을 근거로 구매비용과 위험 감소에 기여하는 통 합 요인을 구체화하는 구성 개념을 도출하였다. 구체적으로 정보파악 동시성과 가격 동일성을 구매 거래비용 절감에 기여하는 1차 수준 변수로 도출하였고, 정보 확장성과 서비스 동일성을 구매 거래 위험 절감에 기여하는 1차 수준 변 수로 도출하여 연구 모델을 개발하였다. 이를 바탕으로 가설을 정의하였고, 서베이를 통하여 수집된 데이터를 이용하여 PLS로 실증 분석을 진행하였다. 통계 분석 결과, 본 논문에서 정의한 1차 변수의 상대적 이점 기여도의 유의한 수 준과 함께 연구 모델의 유효성이 검증되었다. 본 연구를 통하여 제시된 시사점은 정보기술 활용 옴니채널 분야의 실무 적 응용과 향후 연구에 유용하게 활용될 수 있다.

사용자 관점 UCA 기술 경제성 분석:QFD 응용

한현수,박선영,박은영,김광용 한국경영과학회 2006 經營 科學 Vol.23 No.3

In this paper, we investigated economic viability of UCA (Ubiquitous Contents Access) technologies from user adoption perspective. UCA technologies are expected to get embedded into media and telecom merging services. Embracing new technologies such as UCA technologies, forged through an industry convergence, means opting for a technological innovation that will have technological as well as economic and strategic implications. As such, we adopted user perspective innovation adoption theories to explore key antecedents affecting consumer acceptance of these emerging technologies. Subsequently, using QFD (Quality Function Deployment) method, the impacts of UCA technical functions on user’s perceived value enhancements are estimated. The QFD analysis result indicates that the new UCA service technologies could achieve about 42% enhancement on user perceived adoption intention compared to existing digital contents service technologies. The proposed analysis framework and findings suggests significant insights for further research.
