최근 시장에서의 경쟁이 기업 간의 경쟁에서 공급사슬 간의 경쟁으로 진화해 감에 따라, 공급사슬관리(이하 SCM)를 고도화하기 위한 기업들의 관심이 높아지고 있다. 특히 다양한 기술적 강점을 갖고 있는 블록체인 기술이 SCM과 결합되면서 블록체인 기반의 SCM 서비스 도입을 검토하고 있는 국내 제조, 유통 기업들이 늘어감에 따라, 우리 기업들의 블록체인 기반 SCM 도입에 영향을 미치는 요인들에 대한 연구가 중요해지고 있는 시점이다. 그러나 기존 블록체인 및 SCM에 대한 수용연구들은 대체로 기술수용모형이나 통합기술수용모형에 기반하여 수행되어 왔다. 그러나 이 두 이론적 기반은 개인의 정보기술 수용을 설명하기에는 적합하지만, 기업을 대상으로 하는 정보기술 수용을 설명을 하기에는 다소 부적합한 한계가 있다. 본 연구는 기술-조직-환경(TOE) 프레임워크 이론을 바탕으로 기업을 분석단위(unit of analysis)로 하는 새로운 관점의 블록체인 기반 SCM 수용모형을 제시하고, 기업들이 새로운 정보기술의 도입을 검토할 때 그 기술이 제공하는 혜택(benefit)과 그 기술로 인해 발생하는 손실(sacrifice)을 종합적으로 고려하는 특성을 반영하고자, 본 연구에서는 가치 기반 수용 모형(Value-based Adoption Model)의 관점을 추가로 적용하였다. 본 연구에서는 제안된 연구모델을 검증하기 위하여 국내 제조, 유통 기업 126곳을 대상으로 설문을 통해 데이터를 수집하였으며, PLS 구조방정식모델을 통해 실증적으로 분석하였다. 분석결과 '비즈니스 혁신', '경로추적', '보안강화'와 같은 기술적 관점의 혜택 요인들과 '비용'과 같은 손실 요인이 블록체인 기반 SCM의 '인지된 가치'에 유의한 영향을 미치는 것으로 나타났으며, 이는 다시 '사용의도'에 유의한 영향을 미치는 것으로 나타났다. 한편 조직적 관점의 '조직준비도'는 '사용의도'에 유의한 영향을 미치는 것으로 나타났지만, 환경적 관점의 '규제환경'은 예상과 달리 '사용의도'에 유의한 영향을 미치지 못하는 것으로 나타났다. 이와 같은 본 연구의 발견은 국내 블록체인 기반 SCM 활성화를 위한 실무적, 정책적 대안을 마련하는데 기여할 수 있을 것으로 기대된다.

Promoting low carbon transportation adoption is important for energy saving. Some prior studies have discussed on environmental values affect low carbon transportation commuting is inconclusive. This study has constructed the environmental values, utility value, and social influence-based low-carbon transportation adoption model through the theory of the technology acceptance model and VBN model and the IS success model. Through the SEM model and stepwise regression analysis, we have found that environmental values positively affect utility value, and utility value also positively affects the behavior adoption of low carbon transportation. The utility value as mediating effect in the relationship between environmental values and low carbon transportation commuting behavior. Besides, we also have found that social influence positively impacts the behavior adoption of low carbon transportation. It better enhances the level of household residents' environmental values and utility values, and social influence for promoting the adoption of low carbon transportation. This present research provides theoretical guidance and suggestions for promoting the development of low-carbon transportation innovation.

In recent years, IPTV attracts great attention along with the digital convergence of communication and media technologies. IPTV combines the advantages of TV and Internet and changes our lifestyle dramatically. In addition, the IPTV service is capable of becoming a new business model which has huge growth potentials in technology-converging marketplaces. This study examines critical factors on the consumer's adoption of the IPTV service. Based on the Innovation Diffusion Theory (IDT), IPTV specific attributes and personal characteristics, we derive eight key factors in the research model. compatibility, ease of use, image, diversity of contents, interactivity, monetary value, social influence, and user satisfaction. Using the partial least square (PLS) method on the data collected through a web-based survey, we test our research model with several hypotheses. From this study, we find that diversity of contents, compatibility and interactivity have a significant indirect effect on the use of IPTV service via user satisfaction, and user satisfaction and social influence also have a significant direct impact on the IPTV use. These findings not only provide practical insights on the consumer acceptance of new technology-converging services, but also help managers to plan their marketing strategies better.

Purpose: Prior studies rarely investigated the effects of the Word of Mouse (WoM) information on consumers' motivation and willingness to purchase a product. Furthermore, few scholars have studied how word-of-mouth information works and they fail to find consistent results. Research design, data and methodology: This study uses a multivariate regression model to investigate the influence of WoM on consumer attitudes and consumer decision-making. It categorizes the quality of WoM into source level and acceptance level, to analyze its influence from a new perspective. A total of 400 surveys were completed, resulting in 336 usable questionnaires for analysis. It was collected in 14 cities from all regions in China. This study constructs a theoretical model of WoM influence on consumers' purchase willingness based on a systematic review of the related literature on WoM quality, perceived value, customer trust, and consumers' purchase willingness. Results: Empirical results reveal that the Internet WoM (consumer's source level and acceptance level) indirectly affects consumer behavior by influencing consumer attitudes. Conclusions: This study provides practical significance and value for merchants to develop better WoM marketing and to establish the reliability of WoM websites. Companies should consider online WoM from the perspective of consumers, thereby improving existing marketing strategies.

The purpose of this study is to investigate a simple present value model Involving earnings (i.e., the earnings discount model) that presumes a relationship between stock prices and earnings. The model suggests a simple linear equilibrium relationship between stock prices and earnings. The tests for cointegration render strong support for the cointegration hypothesis between stock prices (Pt) and earnings (Xt) even at the one-percent significance level. The tests are based on residuals from a cointegrating regression of Pt on Pt+l + Xt. This suggests that there is a stable long-nu equilibrium relationship between stock prices and earnings. The results of the tests lead to the acceptance of the present value model of stock prices involving earnings.

New drug discovery and development research enable clinical treatment that saves human life and improves the quality of life, but the possibility of success with new drugs is significantly low despite a long time of 14 to 16 years and a large investment of 2 to 3 trillion won in traditional methods. As artificial intelligence is expected to radically change the new drug development paradigm, artificial intelligence new drug discovery and development projects are underway in various forms of collaboration, such as joint research between global pharmaceutical companies and IT companies, and government-private consortiums. This study uses the TOE framework and the Value-based Adoption Model, and the technical, organizational, and environmental factors that should be considered for the acceptance of AI technology at the level of the new drug research organization are the value of artificial intelligence technology. By analyzing the explanatory power of the relationship between perception and intention to use, it is intended to derive practical implications. Therefore, in this work, we present a research model in which technical, organizational, and environmental factors affecting the introduction of artificial intelligence technologies are mediated by strategic value recognition that takes into account all factors of benefit and sacrifice. Empirical analysis shows that usefulness, technicality, and innovativeness have significantly affected the perceived value of AI drug development systems, and that social influence and technology support infrastructure have significant impact on AI Drug Discovery and Development systems.
