Hybrid Imprint Lithography (HIL) is proposed where photolithography and imprinting processes are employed. Fabrication step of multilevel or three dimensional patterns is suggested. The method of controlling residual layer thickness after imprinting is developed. The thickness of residual layer changes lineally with imprinting time and can be controlled. Polymer patterns fabricated by this HIL is demonstrated.

본 논문에서는 트레드밀의 전원공급을 보조하는 압전소자를 이용한 자가발전형 트레드밀을 제안한다. 이를 위해 기존 트레드밀의 발판을 압전소자 발판으로 교체하고, 트레드밀의 발판에 발전된 전기를 저장하기 위한 충전지를 두며, 해당 발판의 압전소자를 이용하여 트레드밀에 재사용 할 수 있는 전원을 생산한다. 본 연구 결과로 트레드밀의 구동전력효율의 향상을 기대할 수 있다.

최근 딸기는 고소득 부가가치 작물로 인식되기 시작하면서 수확작업에 노력이 적게 들고, 재배 및 작업 환경이 개선된 딸기 수경재배에 관심이 높아지고 있다. 현재 우리나라에서도 한국형 배양액 자동공급시스템을 개발하여 보급하기 시작하였지만 딸기 수경재배에서는 배양액의 EC와 pH관리 및 배양액의 급액에 따른 적절한 배액량 구명이 가장 시급하게 필요한 사항이다. 본 논문에서는 생육과 밀접한 관계가 있는 딸기 수경재배 생육 정보를 수집하는 장치를 개발하였고, 이 장치를 통해 딸기 수경재배 생육 데이터들을 수집하고 분석하여 딸기 수경재배 농가에 균일화 된 품질생산 및 수확량 증대에 기여할 수 있을 것으로 기대된다.

Microblogging services (such as Twitter) are the representative information communication networks during the Web 2.0 era, which have gained remarkable popularity. Weibo has become a popular platform for information dissemination in online social networks due to its large number of users. In this study, a microblog information dissemination model is presented. Related concepts are introduced and analyzed based on the dynamic model of infectious disease, and new influencing factors are proposed to improve the susceptible-infective-removal (SIR) information dissemination model. Correlation analysis is conducted on the existing information dissemination risk and the rumor dissemination model of microblog. In this study, web hyper is used to model rumor dissemination. Finally, the experimental results illustrate the effectiveness of the method in reducing the rumor dissemination of microblogs.

This paper presents the system design, implement, and measurement results of the testbed for the wireless RF energy harvesting system. The developed testbed can be used for RF power transfer and data communication using the 2.4 GHz and 900 MHz frequency bands. It allows to evaluate the system performances for the RF power and data transmission. The testbed can also be used to develop algorithms for efficient energy harvesting.

The Ministry of Construction and Transportation (MOCT) has been constructing a nationwide soil information DB since 2000, as basic data for the construction of 'underground geographical information,' a project under the 2nd National Geo-spatial Information System (NGIS) master plan. The inputted soil information includes not only underground conditions such as the layer depth, type, color, and groundwater level, but also engineering information that can be applied to construction work design, such as on the standard penetration test and the compression test. It is difficult to use this information in soil analysis and design, however, because only the test results are currently available. A web-based geo-spatial information system was developed in this study to facilitate the effective application of the soil information database (DB). First, the space information, layer information, and engineering test information were loaded from the soil information DB in real time, and the earth volume, bearing capacity, and settlement were calculated to develop a web client that will evaluate the ground softness and liquefaction. It seems that the soil information DB can be actively applied to the planning and design of construction works using this system.

In this paper we will discuss a general idea about an information system which provides information a user really needs in user's authentication. We will discuss how RFID could be applied for this kind of system especially from the standpoint of using RFID as a way to collect information of personal belongings. Also we will discuss security issues of using RFID as a component of the proposed system because while RFID could provide usefulness, it could also be very dangerous for revealing private information without user's awareness.
