Complementary metal-oxide-semiconductor (CMOS) technology is now facing a power scaling limit to increase integration density. Since 1970s, multi-valued logic (MVL) has been considered as promising alternative to resolve power scaling challenge for increasing information density up to peta-scale level by reducing the system complexity. Over the past several decades, however, a power-scalable and mass-producible MVL technology has been absent so that MVL circuit and system implementation have been delayed. Recently, compact MVL device researches incorporating multiple-switching characteristics in a single device such as 2D heterojunction-based negative-differential resistance (NDR)/transconductance (NDT) devices and quantum-dot/superlattices-based constant intermediate current have been actively performed. Meanwhile, wafer-scale, energy-efficient and variation-tolerant ternary-CMOS (T-CMOS) technology has been demonstrated through commercial foundry. In this review paper, an overview for MVL development history including recent studies will be presented. Then, the status and its future research direction of MVL technology will be discussed focusing on the T-CMOS technology for peta-scale information processing in semiconductor chip.

정보기술 교육과정의 설계는 매우 어려운 작업이다. 비교적 짧은 개설 역사, 정보기술 자체의 급속한 발전, 정보 활용과 정보소양에 대한 사람들의 인식 차이 등으로 인하여 교육내용의 선정이 매우 어렵기 때문이다. 이에 다른 나라의 경우를 비교하여 교육과정 설계의 효과성을 제고할 필요가 있다. 이 논문은 이러한 취지에서 최근 눈부신 경제 발전을 이룩하면서 정보화 교육에 깊은 중시를 보이고 있는 중국의 정보기술교육과정의 변천과정과 현실상황 및 특징을 분석하였다. 또한 중국의 정보기술 교육과정 중에서 한국의 새로운 컴퓨터 교육과정 설계에 채택 가능한 장점들을 제시하였다. 중국의 초중등학교 정보기술교육과정의 특징은 (1) 안정된 수준의 정보기술 기초지식과 기본기능 교육, (2) 문제해결을 위한 정보기술 활용교육, (3) 정보기술의 심화된 탐구와 프로젝트 학습을 통한 개별화 교육, (4) 체계적으로 배정하고, 통합적으로 진행하는 정보기술교육과정으로 요약할 수 있다.

Including technical device and general information system, the information-technical(IT) system is defined as the technical system for acquiring, processing, storing and transferring information to a person. This paper presents Knowledge-based Heuristic Evolution Model for creating the advanced information-technical system. This Evolution Model is derived from the historical review on definition of evolution, the research on the architecture of the general IT system, history of IT system, technology innovation theory and multi-case study research. The evolution model is applicable to the conceptual creation of the advanced product in R&D organization requiring development methodologies like rapid-prototyping to develop next generation product. For the detailed theoretical construction and practical application of Evolution Model, the case study research based on action research is performed. the object of the case study is mobile device, especially mobile hand-held phone. Thus, we obtain the Evolution Model for creating the advanced information-technical system.

식품에 대한 안전성 요구는 사회가 선진화되고 식품산업의 발달과 함께 식생활 양식 변화와 소비자의 인식변화로 인해 사회적 문제로 크게 대두되었다. 소비자들은 자신이 소비하는 식품에 대하여 더 많은 정보를 요구하고 있으며, 유통체계에서 발생하는 식품 스캔들에 민감하게 반응한다. 이와 같은 식품안전에 대한 관심 속에 블록체인 기술은 식품사기나 유통 중의 잘못된 식품 관리에 효과적으로 대응하는 수단으로서 주목을 받고 있다. 이는 식품의 공급망에서 이력추적의 정확성과 믿음을 담보함으로써 거래자 간 신뢰를 구축하고 안전한 식품 유통을 보장할 수 있기 때문이다. 본 연구에서는 농식품의 이력, 유통, 안전, 품질과 신선도 등 농식품이 갖고 있는 각종 정보를 공급자와 소비자 및 유통관계자에게 제공하고 관리할 수 있는 차세대 농식품 유통시스템을 제안한다. 생산, 가공, 유통, 판매, 소비 전 과정에서의 제품 상태 및 유통 상황 정보를 언제 어디서나 실시간으로 모니터링하고 제어할 수 있으며, 사용자는 사용자가 앱(App)을 통하여 각 식품의 안전 수준을 실시간으로 확인할 수 있다.

This article proposes to consider the experience of using information and communication technologies in educational processes and social practices of Ukrainian universities. The history of the introduction of information and communication technologies in the development of the higher education system is considered, the system of organizing the information space of universities is investigated. The distinctive features of the structure of a single information space, as well as distance e-learning technologies are highlighted. Empirical material obtained in the course of sociological research is used to discuss specific examples of the use of ICT in universities.

In construction industry, workers' accident rates are relatively high compared to those of other industries. These high accidents rates are mostly due to the characteristics of construction process. In order to effectively reduce the accident rates, it is required to develop not only immediate measures but also long-term programs of instruction, training, and education. In addition, well-analyzed information on past history is required for the prevention of accidents. By examining about 800 cases of construction accidents that happened between Jan. 1992 and Dec. 2000, this paper developed an information system that provides appropriated safety information to the construction workers. This system is expected to contribute to the workers' safety in construction industry.

Recently, the public interest for infrastructure safety has been growing, but the process of data acquisition and management system for safety is being carried out in an inefficient manner. The data obtained during the inspection for the safety of infrastructure tends to be documented using papers, which is not efficient in the stage of post analyses. The information technology (IT), which is rapidly being developed, is applied to the new system as a solution. Information technology provides valuable tools for converting and generating digital data, handling the history of defects, and assessing the condition and estimating the service life of infrastructure. The purpose of this paper is to introduce Infrastructure Management System(IMS). It is expected that the IMS would minimize the manpower, time and maintenance cost, and improve the safety of infrastructure.

The type printing of first Ch'ing dynasty term in China is worthy to be studied because the type printing during that period included metal type, wood type, and clay type as well as the development phase was similar to Chosun dynasty culturally and technologically. This paper studied typography during the first Ch'ing dynasty term, including Shunzhi(1662-1722), Yongaheng(1723-1735), Qianlong(1736-1795), Jiaqing(1796­1820) period. The main results of the study is as follows. 1. The main body of type printing was bookstore, lecture-hall, and individual as well as the royal court that is the central government. 2. The content of type edition covers classics, history, philosophy, and literary works. Specifically, even though Wuyingdienjuzhenban series is excluded, the content includs study of the classics, class of the history, class of the philosophy, literature works that include collection works and novel and government official bulletin. 3. The printing technique of bronze type was very popular In Beijing. Jiangsu, and Taiwan. It's scale and production technique was more elaborate than in Ming dynasty. 4. Wood type was very popular in Beijing, Jiangsu, Zhejiang, Anhui, Sichuan, and Fujian. In addition to wood type, chinese ware type was applied to book printing in Shandong. However, most of them were wood type and they were used after Qianlong period. 5. The production technique of type was skilled enough to present the fine view of a style of type. The typesetting technique was improved as much as woodblock printing. With regard to the making technology of Chinese ink, the light and darkness of chinese ink was not even sometimes. But, the technology was improved significantly when comparing with the failure experience of printing that chinese ink was not developed in early type invention. 6. In case that the book was printed in bookstore with the intention of profit and the number of book was large, the proofreading attitude was rough. However, overally, it was made correction carefully applying the various methods of proofreading. 7. The support of government made a great contribution in the area of all printing technology, including production, typesetting, and brushing of type.
