Thermopiezoelectric method, using poly silicon heater and a piezoelectric sensor, was proposed for writing and reading in a probe based data storage system. Resistively heated tip writes data bits while scanning over a polymer media and piezoelectric sensor reads data bits from the self-generated charges induced by the deflection of the cantilever. 34${\times}$34 array of thermopiezoelectric nitride cantilevers were fabricated by a single step wafer level transfer method. We analyzed the noise level of the charge amplifier and measured the noise signal. With the sensor and the charge amplifier 20mn of deflection could be detected at a frequency of 10KHz. Reading signal was obtained from the cantilever array and the sensitivity was calculated.

The Quality of human living depends on the environmental quality of the region sustaining the life. The environmental deterioration of the modern society is due to mechanical environmentalism. For the better quality of the life, The changes of recognition and attitude on the environments are required. These changes of mind are also important in environmental education for teenagers. The 7th national curriculum, officially anounced December 1998, focuses on the change of attitude to environments and practical behavior in real life for “Environments”, the environmental education curriculum in middle school. Basic elements of the curriculum are cultivation of the pro-environmental thinking, multi-levelling of teaching materials and methods, and encouraging of student participating activity. Actually, the curriculum construction is composed of stepped-levelling of teaching and learning, reasonable contents volume, encouraging of student practice, and suggesting of evaluation standards of textbook writing. Three main subjects of environmental education for middle school consist of (1) man and environment, (2) recognition of environmental problem, and (3) protection activity for environment. Methodology of environmental education can include multi-disciplinary approaches, variable teaching methods, and continuing evaluation of student practice and participation attitude. Environmental education for teenagers relating to the 7th national curriculum focuses on recognition of the environmental problems and practice activity in daily life. The recognition includes considering relationship of human life to environment, solving environmental problems in regional context, and development of comprehensive understanding concept of the environments. For the practice education, variable teaching methods, such as field survey and application of multi-media, are needed.

With a rapid development of smart devices, the consumption of digital media contents has become much faster. As a result, there has been a rising demand for diverse stories, and cultural archetypes have been reproduced to crate these stories. An archetype is an act inherent in collective unconsciousness. Since it is a prototype stemming from imagination and experiences, the distortion or deterioration of the archetype could even threaten the identity of national tradition. This study analyzed western contents which have been successful and domestic ones that have failed in the reproduction of their archetype, investigated aspects in the reproduction of cultural archetypes and reviewed future storytelling methodology.

The objective of this study was to follow up changes in knowledge related to the mathematics education field work of preliminary early childhood teachers. The subjects of this research were 28 students who were taking mathematics education courses in early childhood education departments at various universities. This research ran for 15 weeks and was conducted through field work relating to mathematics education. The study collected data from pre-service teachers' knowledge, the diagram of concept, writing journals, interviews, and materials from the internet. Through this procedure, pre-service teachers' knowledge for mathematics education could later be expanded, ordered, and integrated. In addition, pre-service teachers not only understood the importance of contents and levels of lesson plans, but also learned how to utilize educational media to make effective lessons. Furthermore, pre-service teachers realized that the mathematical concepts of students could be expanded depending on the contents and methods of pre-service teachers' lesson plans and students could then apply these concepts into daily situations.

논문이나 문서를 작성하다 보면 주로 자신이 사용하는 개인용 컴퓨터(PC)에서 작업한다. 다른 PC에서 문서 작업을 하게 되면, 자신이 사용하던 PC의 자료나 작업 환경이 틀리기 때문에 불편함을 겪게 된다. 다른 PC에서 작업해야 하는 경우에 워드프로세서 등의 기존에 작성된 문서 프로그램을 일일이 설치해야 한다. 그리고 모아둔 문서 자료 또한 번번이 이동 저장 매체 등으로 자료 이동 작업을 해야만 한다. 이 외에도 아주 사소한 문제들이 자신의 PC 이외의 환경에서 문서 작업을 힘들게 한다. 요즘은 인터넷이 발달해 있기 때문에, 인터넷의 특정한 공간에 자신의 자료를 저장하는 방식으로 해결하려 한다. 하지만 인터넷이 대중화된 아직까지도 인터넷 장애는 빈번히 일어나거나, 뜻하지 않는 일로 인터넷 연결을 보장 할 수가 없으므로 이러한 방법에도 한계가 존재한다. 본 논문에서는 모든 작업 환경을 맞춰주지는 못하지만, 자신이 수집한 자료와 문서 작업이 동시에 한 시스템에서 이루어지도록 하는 방법을 제안한다. 또한 본 시스템은 이동형 저장 매체에 자리 잡고 있어서 이를 휴대하기만 하면 웹브라우저가 있는 다른 PC에서 자신의 작업을 그대로 이어갈 수 있는 그러한 시스템을 제안하고자 한다.

For Romantic women writers the paratext itself is essentially a masculine literary space affiliated with established writing practices; however, this paper suggests that Charlotte Turner Smith's mode of discourse in her use of notes and their relation to the text proper are never fixed in her contemplative blank-verse long poem, Beachy Head (1807). Even though the display of learning in the paratext partly supports the woman writer's claim to authority, this paper argues that Smith's endnotes also indicate her way of challenging the double bind for women writers, summoning masculine authority on the margins of her book while simultaneously interrogating essentialist thinking and instructions about one's identity in a culture and on the printed page. The poem shows how the fringes of the book can be effectively transformed from a masculine site of authority to an increasingly feminized site of interchange as Smith writes with an awareness of patriarchal, imperial abuses of power in that area of the book. There is a persistent transgression of cultural/textual boundaries occurring in Beachy Head, which explores the very scene and languages of imperial encounter. Accordingly, if Wordsworth's theory of composition suggests a subjective and abstract poetic experience-an experience without mediation-in which its medium's purpose seems to be to disappear from the reader's consciousness, an examination of the alternative discourse of self-exposure in Smith's poem reveals the essentially fluid nature of media-consciousness in the Romantic era, which remains little acknowledged in received accounts of Romantic literary culture.

The column-oriented database storage is a very advanced model for large-volume data transactions because of its superior I/O performance. Traditional data storages exploit row-oriented storage where the attributes of a record are placed contiguously in hard disk for fast write operations. However, for search-mostly data warehouse systems, column-oriented storage has become a more proper model because of its superior read performance. Recently, solid state drive using flash memory is largely recognized as the preferred storage media for high-speed data analysis systems. In this research, we propose a new transaction recovery scheme for a column-oriented database environment which is based on a flash media file system. We improved traditional shadow paging schemes by reusing old data pages which are supposed to be invalidated in the course of writing a new data page in the flash file system environment. In order to reuse these data pages, we exploit reused shadow list structure in our column-oriented shadow recovery(CoSR) scheme. CoSR scheme minimizes the additional storage overhead for keeping shadow pages and minimizes the I/O performance degradation caused by column data compression of traditional recovery schemes. Based on the results of the performance evaluation, we conclude that CoSR outperforms the traditional schemes by 17%.
