Surveying the literature of architecture since the nineteenth century, one can identify two dominant but problematic attitudes, among several, that pursue the task of defining what modern architecture is and should be. The first is the search for meaning and the second is the pursuit of form. This study, following Michel Foucault, asserts that the dual formation of meaning and form is a historical product of modernity and belies architecture's uncritical dependence on language since the nineteenth century. This study is a critique and historical analysis of this pernicious reliance, and constitutes a first step towards thinking of alternative relations between 'words and architecture' in the modern world. In reconstructing this problematic, the paper has called on Foucault's seminal The Order of Things. The study follows his construction of the Renaissance, the Classical and the Modern episteme, and in brief fashion, reconstructs the relation between language and architecture in each episteme. In analysing the Modern, the study focuses on Hegel's Lectures on Aesthetics. Hegel placed architecture in a genre hierarchy within which architecture, because of its material basis, was fundamentally limited in its ability to express the Spirit. For Hegel it was, among the arts, poetic language, and beyond art, the language of philosophy, through which the Absolute Spirit could be atttained. Much of post-nineteenth century architecture has remained within the shadow of Hegel, where architecture's materiality is perceived to be a burden, and in order to secure its relevance in modern society, architecture was deemed to pursue the role of language. As the most recent and sophisticated example of architecture's pursuit of form, the paper analyses the work of Peter Eisenman. Though Eisenman's theoretical writings are replete with post-Hegelian rhetoric, his architecture remains dependent upon the model of language, albeit a structuralist one. The paper concludes that ultimately, the pursuit of meaning and form is unable to face the crucial issue of value in modernity. While the former decides to easily what it is, the latter evades the issue itself. The second installment of this ongoing study will pursue a third possibility alluded to by Foucault, where language remains silent, pointing only to its 'ponderous' material existence.

언어 모델은 음성 인식이나 필기체 문자 인식 등에서 다음 단어를 예측함으로써 인식률을 높이게 된다. 그러나 언어 모델은 그 도메인에 따라 모두 다르며 충분한 분량의 말뭉치를 수집하는 것이 거의 불가능하다. 본 논문에서는 N그램 방식의 언어모델을 구축함에 있어서 크기가 제한적인 말뭉치의 한계를 극복하기 위하여 두개의 말뭉치, 즉 소규모의 구어체 말뭉치와 대규모의 문어체 말뭉치의 통계를 이용하는 방법을 제시한다. 이 이론을 검증하기 위하여 수십만 단어 규모의 방송용 말뭉치에 수백만 이상의 신문 말뭉치를 결합하여 방송 스크립트에 대한 퍼플렉시티를 30% 향상시킨 결과를 획득하였다.

The thesis is to look for the method of applying process drama for bilingual education in multicultural society. This purpose can be resolved in three steps: first, to understand the purposes and functions of education changing to multicultural society; second, to survey the need of bilingual education conformed to its purposes and functions; last, to understand the theoretical background of process drama and seek the method of utilizing it to bilingual education. Recently, the Korean society is also changing to multicultural society with international marriages and immigrant workers. But they have difficulties in communicating in Korean, and their children have even the same. Under the basis of multiculturalism wanting peace and mutual respect between cultural groups, they have to be educated in equality. This is why the bilingual education is needed in our society. Process drama, a widely used term for educational drama in Britain, claims its effectiveness for L1, L2 and bilingual education, for the principal medium in drama is language and what drama delivers is related to meaningful human experiences. It is also supported on script theory of linguistic therapy. Kase-Polisini classifies the developmental process of education drama into 1) planning, 2) playing and 3) evaluation. This process can be applied to educational drama for language as well. Rather, educational drama applying to bilingual education has even more availability with the varieties of group organization and subject matter. Conclusively speaking, the group of dual language schools can be organized into 1) mother-tongued group, 2) mother-tongued and L2 group, 3) multilingual group, or 4) L3 group in educational drama activity, as the class generally consist of the mixed multilingual children. And the subject matter can deal with 1) the Korean society and culture, 2) the society and culture of the purposed language country, or 3) the society and culture of the third nations.

Much has already been learned about what goes on in the minds of second language writers as they compose, yet, oddly enough, until recently little in the L2 research literature has addressed writing and mental imagery together. However, images and imaging (visual thinking) play a crucial role in perception (the basis of mental imagery), in turn, affecting language, thinking, and writing. Many theorists of mental imagery also agree that more than just language accounts for how we think and that imagery is at least as crucial as language. All of these demands, to be sure, are compounded for EFL students, which is why I investigate EFL students' writing process, focusing on the use of mental imagery and its relationship to the writing. First I speculate upon some ways that imagery influences EFL students' composing processes and products. Next, I want to explore how and whether the images in a writer's mind can be shaped effectively into a linear piece of written English in one's writing. I studied two university undergraduate EFL students, L and J. They had fairly advanced levels of English proficiency and exhibited high level of writing ability, as measured by TOEFL iBT Test. Each student wrote two comparison and contrast essays: one written under specified time limitations and the other written without the pressure of time. In order to investigate whether the amount of time in itself causes differences within an individual in imagery ability, the students were placed under strict time constraints for Topic 1. But for Topic 2, they were encouraged to take as much time as necessary to complete this essay. Immediately after completing their essays, I conducted face-to-face retrospective interviews with students to prompt them for information about the role of imagery as they write. Both L and J have spent more time on their second (untimed) essays. Without time constraint, they produced longer texts on untimed essay (149 vs. 170; 186 vs 284 words). However, despite a relatively long period of time spent writing an essay, these students neither described their images nor detailed them in their essays. Although their mental imagery generated an explosion of ideas for their writings, most visual thinking must merely be a means toward an end-pictures that writers spent in purchasing the right words or ideas.

In this study an one-board micom controlled precision temperature control system has been developed. The digital temperature control system is consisted of an one-board micom as digital controller, a 12-bit A/D and D/A converter, a power amplifier, a NTC thermister, a preamplfier and a heat chamber. An operating control program for the control system was written in Z80 machine language. A Dual-PID predictor control algorithm was proposed. Experments were conducted with different sampling time and limitted error value. As a result, the temperature in a heat chamber can be well controlled within +- 0.2 .deg.C when the sampling time was applied to 10 sec and the limitted error value +- 0.5 .deg.C under the dual-PID predictor control algorithm. By means of one-board micom overall system has been reduced in size and volume, thus the system becomes compact and less expensive.

In this paper, a remote submersion warning system based on multi-mode optical fiber(MMF) sensors and a wireless sensor network(WSN) are proposed. To improve the reliability and stability of the sensors, the dual optical fiber sensors combined to the optical coupler are demonstrated. A slave zigbee as a wireless sensor module was used as a platform to monitor and record the signal from the MMF sensors and then transmits these information to a master zigbee wirelessly. The monitoring system running the $LabVIEW^{(R)}$ software was connected to the internet to support the short message service(SMS) through extensible markup language(XML) web service. No matter where the managers are, they can always receive the real-time remote-monitoring data for safety check.

This study has examined, first of all, one of unique characteristics of picturebook, so-called dual audience. To be more exact, this paper aimed at exploring the flexibility of picturebooks that allows both of children and adult reader to enjoy them. For this, we analysed Piggybook by Anthony Browne that so far has been read as a traditional picturebook with a single distinctive narrative rather than as a postmodern picturebook with multiple narratives, centering on paradox and irony. The results of this study were as fallows: Piggybook has the potential of multiple readings and meanings for a variety of audiences. Above all, this picturebook raises not only the question about the gender roles but also the one about representation of reality through the language.

Brain tumor segmentation problem has challenges in the tumor diversity of location, imbalance, and morphology. Attention mechanisms have recently been used widely to tackle medical segmentation problems efficiently by focusing on essential regions. In contrast, the fusion approaches enhance performance by merging mutual benefits from many models. In this study, we proposed a 3D dual fusion attention network to combine the advantages of fusion approaches and attention mechanisms by residual self-attention and local blocks. Compared to fusion approaches and related works, our proposed method has shown promising results on the BraTS 2018 dataset.
