The world is in the process of a structural change related to ICT convergence knowledge industries. ICT is leading to the creation of new products and services, and is making our lives more convenient, safer, and more efficient. In advanced countries, many studies have been conducted with the goal of developing new business models converged with ICT, and this is also the case in the food industry. Korea possesses world-leading ICT, and if this ICT is applied to the food industry, a world-class new business model can be developed. The u-Food System, which is in the process of development in Korea, is a next-generation food system that can allow food providers, consumers, and distributors to access various types of information about food products, including traceability, distribution, safety, quality, and freshness, and manage this information. It is a future food system that converges ICT, biotechnology and sensing technology with food. Based on the u-Food System, this paper will introduce the status of current smart quality distribution technologies that converge ICT (such as sensor tag, sensor network, LBS, GIS, and CDMA) with food technologies (such as traceability, quality, distribution management) to manage the safety and quality of fresh food in the distribution process.

The Wolmi Eunha-Rail in Incheon is connecting Wolmido and Incheon Station with an elevated monorail road supported by piers. This railroad system is characterized by driverless automatic operation and moving-block based control. The main technology applied to this signal-controlled system is CBTC (Communications-Based Train Control) which based on wireless communications. The CBTC system is simple in that composition so that can minimize field facilities and lowers costs of construction and maintenance. This CBTC system is emerging as a major signal-controlled system in the future metro market.

Campus-based universities have provided face-to-face instruction traditionally. But recently, it is becoming a trend that they provide blended learning which combines e-learning and f2f instruction. Therefore, traditional university has been installing the ICT related convenience for the faculty and students to use easily to their classes. The purpose of this study is to develop quality indicators of ICT-related support for proper blended learning in traditional campus-based universities. This indicators are used for measuring the quality of ICT-related services at university level for quality education. To this end, first, we reviewed literature about quality indicators of university evaluation and e-learning. Second,we did case study. We selected and analyzed one university for a case, And we identified what elements are perceived important to faculty for more efficient use of technology to their class. Third, we summarized all this data and established the quality indicators framework of ICT-related components for blended learning in campus-based universities. Then, these indicators were revised after the expert evaluation. And then 10 experts and practitioners scored importance rating. Finally, we sum them up to 17 indicators and 48 sub-indicators in three phases (input, process, output). Among them, e-learning related organization or body, usability of Learning Management System, and quality assessment system got the highest scores. These indicators are supposed to contribute to measure the quality of ICT-related environment for blended learning and to provide informations about what is required for efficient blended learning in the campus-based universities.

본 논문은 정보화 시대에 요구되는 역량의 개념과 유형을 정의하고 정보화 시대의 역량 특성이 반영된 정보화 역량 검사도구 개발에 대한 고찰이다. 우리나라에서는 한국교육학술정보원을 중심으로 2007년부터 초 중 고등학생들의 ICT 리터러시 검사 시스템을 개발하여 국가 수준의 ICT 리터러시를 평가하고 있다. 그러나 개발된 웹기반의 선다형과 수행형 ICT 리터러시 검사 시스템은 정보화 역량 고유의 특성을 완전히 반영하지는 못하고 있다. 본 연구는 현재 OECD에서 연구개발 중인 PIAAC(Programme for the International Assessment of Adult Competencies)의 컴퓨터 기반 정보화 역량 검사도구를 살펴봄으로써 보다 효과적이고 효율적인 정보화 역량 검사도구 개발을 위한 시사점을 제안한다.

This paper proposes a vision-based underwater laser scanner with separate structures for an underwater camera and a line laser projector. Because the two devices can be adaptively placed regardless of the features of the unmanned underwater vehicle (UUV), the scanner has significant advantages in relation to its availability and flexibility. Position calibration between the underwater camera and laser projector guarantees a 3D measuring performance with high accuracy. To verify the proposed underwater laser scanner, a test-bed system was manufactured, which consisted of the laser projector, camera, Pan&Tilt, and Attitude and Heading Reference System (AHRS). A camera-laser calibration test and simple 3D reconstruction test were performed in a water tank and the experimental results are reported.
