Purpose - As overseas direct purchase transactions using e-commerce increase, the scale and scope of international trade are diversified, and the transaction volume using online platforms in e-commerce is increasing. The e-commerce market share will become more important because it is not only a medium connecting B2C, but also because it will expand the scope of trade. This study aims to reveal the factors that influence purchase intention according to Korean-Chinese consumers in e-commerce. In addition, the study has comprehensively confirmed the influence between each factor in the e-commerce environment by integrating and analyzing the characteristic factors of online information sources and platforms in one structural equation. Finally, the study confirmed that there is a significant difference in the influence relationship between Korean and Chinese consumers. Through this, the study will contribute to content production in the e-commerce market according to the target market and the expansion of the mutual entry of Korea and China. Design/methodology - This study aims to confirm the mediating effect of the details of the online information source characteristics and platform characteristics when the perceived quality affects purchase intention. It is confirmed that the factors affecting Korean and Chinese consumers differ. Findings - It was confirmed that differences exist according to the group of Korean or Chinese consumers for the entire research model. In the case of Korean consumers, the mediating factors when perceived quality affects purchase intention are expertise, reliability, entertainment, informativity, and convenience; in the case of Chinese consumers, the factors are expertise and informativity. Originality/value - This study proved that Korean and Chinese consumers cannot be regarded as having the same characteristics, and therefore, strategies aimed at each e-commerce market should be differentiated. In addition, although previous studies on online information sources and platform characteristics were not integrated, this study confirmed a significant influence relationship among the factors that could affect purchase intention in the actual e-commerce environment.

Biological data and analysis tools are accumulated in distributed databases and web servers. For this reason, biologists who want to find information from the web should be aware of the various kinds of resources where it is located and how it is retrieved. Integrating the data from heterogeneous biological resources will enable biologists to discover new knowledge across the specific domain boundaries from sequences to expression, structure, and pathway. And inevitably biological databases contain noisy data. Therefore, consensus among databases will confirm the reliability of its contents. We have developed WeSAT that integrates distributed and heterogeneous biological databases and analysis tools, providing through Web Services protocols. In WeSAT, biologists are retrieved specific entries in SWISS-PROT/EMBL, PDB, and KEGG, which have annotated information about sequence, structure, and pathway. And further analysis is carried by integrated services for example homology search and multiple alignments. WeSAT makes it possible to retrieve real time updated data and analysis from the scattered databases in a single platform through Web Services.

Differing from the fixed-type, the dynamic motion of floating-type offshore wind turbines is very sensitive to wind and wave excitations. Thus, the sensing and monitoring of its motion is important to evaluate the dynamic responses to the external excitation. In this context, a monitoring system for sensing and processing the wind-induced dynamic motion of spar-type floating offshore wind turbine is developed in this study. It is developed by integrating a 1/00 scale model of 2.5MW spar-type floating offshore wind turbine, water basin equipped with the wind generator, sensing and data acquisition systems, real-time CompactRIO controller and monitoring program. The scale model with the upper rotatable blades is installed within the basin by means of three mooring lines, and its translational and rotational motions are detected by 3-axis inclinometer and accelerometers and gyroscope. The detected motion signals are processed using a real-time controller CompactRIO to calculate the acceleration and tilting angle of nacelle and the attitude of floating platform. The developed monitoring system is demonstrated and validated by measuring and evaluating the time histories and trajectories of nacelle and platform motions for three different wind velocities and for eight different fairlead positions.

A novel architecture and proprietary electronic inks were developed to provide disruptive digital-media solutions based on an electrokinetic technology platform. The flexible reflective electronic media (eMedia) was fabricated by imprinting three-dimensional microscale structures with a roll-to-roll manufacturing platform. The HP technologies enable the required attributes for eMedia, such as low power, transparency, print-quality color, continuous levels of gray, and lowcost scalability. Pixelation was also demonstrated by integrating with the prototype oxide thin-film transistor backplane, and the system architecture was further developed by stacking primary-colorant layers for color reflective-display application. The innovations described in this paper are currently being developed further for the eSkins, eSignage, and ePaper applications.

Since the late 1990s, the Korean government has attempted to develop the Architectural Information System (AIS, SEUMTER), led by the Ministry of Construction and Transportation, in order to improve civil complaint convenience and administrative efficiency in architectural administration. Since then, for nearly 30 years, the Korean government has been continuously upgrading the SEUMTER system. Based on these advancement projects, it is now possible to conduct civil affairs through the Internet, and civil petitioners can file complaints with government offices without visiting and without documents. In addition, statistical work and performance management became possible in real time for civil servants. And recently, by clouding the SEUMTER system, intelligent services have become possible. In this paper, the development process of the SEUMTER was divided into four stages and evaluated, and the main success factors were derived. The main success factors of SEUMTER are 1) Promotion as a National Agenda - Leadership of the President and Ministers, 2) Outsourcing of Information System Development and Dissemination, 3) Overcoming Selfishness between Ministries - Integrating Building Permits System and Building Ledger Systems, 4) Continue to Promote Information System Advancement. Subsequently, three global diffusion strategies for SEUMTER were presented: 1) the Need to Establish Globalization Strategy: Linkage with Smart City Business, 2) Small and Medium-sized System Model Needed for Globalization and ODA, and 3) System Success Needs to be Publicized Internationally.

A number of therapeutic drugs have been developed from functional chemicals found in plants. Knowledge of plants used for medicinal purposes has historically been transmitted by word of mouth or through literature. The aim of the present study is to provide a systemic platform for the development of lead compounds against breast cancer based on a traditional medical text. To verify our systematic approach, integrating processes consisted of text mining of traditional medical texts, 3-D virtual docking screening, and in vitro and in vivo experimental validations were demonstrated. Our text analysis system identified rutin as a specific phytochemical traditionally used for cancer treatment. 3-D virtual screening predicted that rutin could block EGFR signaling. Thus, we validated significant anti-cancer effects of rutin against breast cancer cells through blockade of EGFR signaling pathway in vitro. We also demonstrated in vivo anti-cancer effects of rutin using the breast cancer recurrence in vivo models. In summary, our innovative approach might be proper for discovering new phytochemical lead compounds designing for blockade of malignant neoplasm including breast cancer.

최근 웹을 기반으로 하는 소프트웨어가 발전하면서, 웹을 통한 서비스가 점차 증가하고 있다. 이것 때문에 많은 연구기관과 보고서들이 웹을 소프트웨어의 플랫폼이라고 부르고 있다. 이렇게 웹 기술이 발전하는 동안 Wireless Sensor Network(WSN)의 미들웨어와 응용 서비스는 데스크탑의 운영체제 기반에서 개발되었다. 그래서 WSN의 기술은 데스크탑 어플리케이션의 한계점을 가지고 있다. 그리고 센서 노드의 하드웨어와 밀접한 관련이 있는 강 결합(Tightly-Coupled) 구조 때문에 WSN의 통합, 응용 서비스 배포, 유지보수 관리 등에 어려움이 있다. 이와 다르게 Web 은 약 결합(Loosely-Coupled)이고 개방된 시스템이기 때문에 Web Service 나 Rich Internet Application(RIA)는 이러한 한계점을 해결할 수 있도록 도와준다. 특히 RIA는 웹 어플리케이션이지만 데스크탑 어플리케이션과 비슷한 사용자환경과 다양한 통신방법을 제공하기 때문에 WSN 응용서비스의 플랫폼이 될 수 있다. 본 연구에서 WSN의 연결성과 접근성을 인터넷으로 확장시키고 RIA를 적용하여 실시간 메시지 시스템을 제안한다.
