The purpose of the study was to explore the conceptual and theoretical fundamentals of learning object. Learning object, a new paradigm for instructional design in the era of information technology, has attracted much research efforts since it has lots of advantages in terms of production efficiency and use effectiveness. A theory for the systematic design of this new instructional design, however, looks far from mature. Since the birth of the idea of a learning object has been found in the field of computer software design, such as object-oriented software development, learning object does not have enough theoretical underpinnings in terms of learning and instruction. The researcher tried to establish theoretical foundations for this new, alien concept as a learning design theory. Relevant research efforts and discourses have been discussed for this purpose.

본 발표에서는 광학적 분석 시스템에 적용 가능한 발광소자(광원)과 수광소자(광센서)를 집적화시키는 모듈(수 발광 집적모듈) 기술을 제시하고자 한다. 이러한 수-발광 집적모듈은 다양한 응용 분야에 적용 될 수 있다. 예를 들어, 광신호 감지를 위한 광통신용 송-수신 모듈(optical communication), 의료/진단 분야에서 단백질/DNA/박테리아 등의 검출 및 분석에 관한 바이오 센서(bio-sensor), 그리고 대기(가스)/수질 모니터링에 관한 환경센서 등 매우 광범위한 분야에 해당되는 요소 기술이라 할 수 있다. 특히, 이들 분야들 중 바이오 물질을 분석하고 검출하는 광학적 바이오 센서 기술은 높은 경제적 가치와 산업적 성장 잠재력으로 인해 오랫동안 활발한 연구가 진행되어 오고 있다. 이러한 광학적 바이오 센서에서 가장 범용적인 방법 중 하나가 항온-항체 면역반응을 기반으로 하는 형광 검출(fluorescence detection) 기법이다. 이러한 시스템은 전체적으로 광원, 광학계, 그리고 센서로 구성되는데 기존에 일반적으로 사용되고 있는 형광 현미경의 경우는 민감도가 우수하다는 장점은 있으나 상당히 고가이고 부피가 크며 복잡한 광학구성으로 이루어져 있다는 한계점을 가지고 있다. 이러한 맥락에서 고민감도를 확보하면서 휴대성, 고속처리, 저가 등의 특성을 가진 시스템에 대한 요구가 갈수록 증가하고 있다. 이를 해결하기 위한 핵심기술 중의 하나가 수-발광 부분을 집적화 시키는 기술이라 할 수 있다. 본 연구에서는 바이오 센서 기술의 하나로서 형광을 측정하여 혈액내의 진단 지표인자를 검출할 수 있는 휴대용 혈액진단기기에 적용되는 소형 수 발광 집적 모듈을 개발하였다. 혈액내의 검출 성분의 양에 따라 형광의 세기가 변화하게 됨으로써 정량적인 검출이 가능한 원리이다. 모듈의 구조는 크게 광원(발광소자), 광학계, 그리고 광센서(수광소자) 세 영역으로 나누어 진다. 광원은 635 nm 적색 레이저다이오드로서 형광체(Alexa Fluor 647/발광파장: 668 nm)를 여기 시키는 기능을 하며 장착된 볼렌즈 의해 샘플의 형광체 영역으로 집광된다. 광학계는 크게 시준렌즈(collimating lens)와 광학필터로 구성됨으로써 샘플로부터 발생되는 광을 적절하게 수광소자로 전달하는 기능을 하게 된다. 여기서 광학필터의 경우는 기본적으로 Distributed Bragg's Reflector(DBR) 구조로써 실리콘(Si) 포토다이오드 상부에 모노리식(monolithic)하게 형성되며 검출 샘플로부터 진행되는 레이저 광(잡음의 주원인)은 차단하고 형광(광신호)만 통과 시키는 기능을 하게 된다. 따라서 신호 대 잡음비(S/N ratio)를 향상시키기 위해서는 정밀한 광 필터링 기능이 요구됨으로써 박막의 세밀한 공정 조건과 구조적-광학적 특성 분석이 수행되었다. 마지막으로 포토다이오드 소자는 일반적인 구조 이외에 중앙에 원형 구멍이 형성된 특별한 구조가 적용된다. 이것은 포토다이오드 구조에 변화를 줌으로써 모듈 구조를 효율적으로 응용할 수 있다는 의미를 갖는다. 또한 포토다이오드의 전기적-광학적 측정 분석을 통해 잡음 및 감도 특성이 세부적으로 조사되며 형광신호를 효과적으로 측정할 수 있음을 확인하였다. 최종적으로 제작된 모듈은 약 $1{\times}1{\times}1cm^3$ 내외 정도의 크기를 갖는다. 요약하자면 본 발표에서는 광학적 바이오센서에 적용할 수 있는 소형 수-발광 소자 집적모듈을 소개한다. 전체 모듈 설계는 최소한의 부피를 가짐과 동시에 측정의 정밀성을 향상시키는데 초점을 맞추어 진행하였다. 세부요소인 광학필터와 포트다이오드의 경우 잡음 및 민감도에 미치는 중요성 때문에 세밀한 공정 및 특성분석이 수행되었다. 결론적으로 독자적인 설계 및 공정을 통해 휴대성 및 정밀성 등의 목적에 부합한 경쟁력 있는 수-발광 소자 집적모듈 제작 기술을 확보하였다.

Among five types of the model textbook based on storytelling, the type of 'Inquiry into history of Mathematics' focuses on adapting the logic of mathematical discovery to the organization of mathematical contents. It enables students to recognize that mathematics has been developed by human needs and creativity while they are engaged in the story about knowledge formation. Moreover the textbook offers the context in which students are able to understand mathematical insights and logics hidden in the subject matter, so that they can reinvent and develop mathematical knowledge. In this study, we found the principles for development of the textbook based on storytelling for 'Inquiry into History of Mathematics' by analyzing the chapter about 'Complex number and Quadratic Equations' of the model textbook. The chapter was implemented in classroom environment and students' understanding of the subject matter and their perception on the textbook based on storytelling were surveyed before and after the implementation. The results showed the possibilities of adapting the textbook based on storytelling and we suggested some implications for further development.

The purpose of this study is to understand the context of cosumers' lives in Korea with a narrative analysis method. The epistemological orientation of eh narrative analysis is Interpretivism, which blends the two polar philosophical perspectives, Empiricism and Rationalism, and includes Narrotology, Hermeneneutics, Semiotics, and Structural Criticism. Narrative analysis takes as its object of investigation the story itself. This study collects eleven narrative plots from four housewives, into which Labov's structural approach is applied. This study shows clearly that the socio-cultural environment in which consumers live has strong influence on their consumption behavior and also reveals that narrativization tells not only about past actions but how individuals understand those actions, that is, meaning.

"ImwonGyeongjeji" is recognized the value which is unparalleled encyclopedia in the world, but that is only evaluate about variously handled with subject area and massive content and also most scholarly research was focusing agriculture which is the domestic situation of published period and "ImwonGyeongjeji" judged as a simple agriculture book. Therefore, this research focus to theory and technique of traditional landscape architecture from science of landscape architecture perspective and it is from "ImwonGyeongjeji" which is known as encyclopedia written by Seo Yu-gu in 19th century Joseon period. For such a contents, "ImwonGyeongjeji" can find a importance that it have value and status for represent of Korea 'landscape architecture statement' which compared with other East Asia in those aspects; 'professional about landscape architecture', 'superiority of composition system', indigenousness suitable for Korea' and 'enhance to superiority value of environmental factor for writing'.

Kant and Lacan strongly criticized the epistemological premise of formal logic. However, Lacan was opposed to Kant in terms of subject, object, knowledge and truth. From the viewpoint of Kant's transcendental logic, formal logic does not have the ability to represent the nature of truth. On the other hand, from the viewpoint of Lacan's psychoanalytic logic, Kant's transcendental logic misunderstands or only partially represents the state of things. But I would like to try to criticize the epistemological premise of the two forms of logic. Transcendental logic takes the evident and new function in that it has studied the necessary condition of content rather than the form of thinking which formal logic considers as his object of study. Transcendental logic evidently studies the categories which dominate our way of thinking. Can we say that the 12 categories which Kant provided are sufficient in explaining the necessity of thinking? Lacan's psychoanalytic logics tells us that Kant's categories are only a kind of metaphor related with hypothesis that tries to explain the possibility of synthetical judge a priori. Is Lacan's psychoanalytic logic sufficient in explaining the possibility of science? It is not sufficient in explaining the objectivity and strictness of science, for it depends on metaphor and metonymy which are useful to literature and unconsciousness. I would like to try to synthesize Kant's transcendental and Lacan's psychoanalytic logic in terms of structure-constructivism which combines both formal and dialectical logic, which is consistent with the ideal of human science, and not blinkered science. My conclusion is that Kant's ethical and esthetical theory should be modified though Lacan's psychoanalytic logic, and Lacan's theory of the unconsciousness revised by Kant's transcendental logic.

In landscape studies, the concept of naturalness was vast in its categories from physical space to cognitive systems, making it difficult to define terms at once. Therefore, this study summarized the concept and evaluation attributes of 'naturalness' used in the literature through systematic review (SR), and identified the scope of individual attributes that constitute the meaning of naturalness. In addition, the individual attributes classified in previous studies were identified as the meaning chain, one of the cognitive linguistic research methods, and applied to papers targeting naturalness among domestic landscape studies to organize a polysemous meaning system. Meaning chain is a suitable method for grasping words whose meaning expands in a chain due to family resemblance around prototypical meaning, and the dimension is classified according to the classification of naturalness evaluation items and a multi-semantic chain system of naturalness concepts discussed in domestic academia. The results of the study are as follows. First, the attributes of naturalness extracted through foreign landscape literature were classified into four areas: nature perceived as wilderness, nature as non-artificiality, nature as visual landscape, and nature as experience, and 13 detailed attributes. Second, these detailed attributes are generally consistent with domestic landscape studies, but their specific cases were different, and a Korean context was presented in perception of time accumulation, also they suggested that there may be a mutual conflict between naturalness attributes.

Hahoebyeolsingut Talnori, which is under permanent performance, has lost its relevance to folklore and rituals of the villagers and has secured the possibility of change depending on the actor's choice. This article seeks to expand the current stuck performance of Hahoe mask play, which has great significance as a play and play for the audience. To this end, We studied the possibility of expanding the performance of Hahoe Talnori by trans-identity of the Choragi. Chorangi character derides yangban, seonbi and monk, who are representatives of the establishment. Those who have a consciousness of potential transformation, those who passively represent the masses, and those who are tacitly authorized by the audience to ridicule the ruling class. The audience feels exhilarated by the super-cool, but at the same time reduces the limits. We transformed Chorangi who is clever but cannot overcome the limits of his status, into a character with a sense of transformation by applying the method of turnning identity and changing identity of the theory of trans-identity. And I applied the method of expansion of the media conversion storytelling theory to create a new Chorangi Madang that conforms to the audience's needs and the spirit of the times. In addition to the performance of Yangban Seonbi Madang(Act of Nobleman and Scholar) which ends with an ambiguous reconciliation, we wanted to complete it in a way that even today's audiences could accept by applying the function of the Hahoebyeolsingut Talnori ambassador and the principle of implementation. And We writed it in a script. This article is meant to be an experimental study that attempted to transform traditional performing arts in the context of new creation of tradition. Preservation and transmission of traditional performing arts are important, but it is necessary to move forward according to the trend and spirit of the times.

This study is an argument that Yeoheon Jang Hyun Gwang's Yeok-Hak-Do-Seol has been on the context of the typical Confucian methodology of self-organization for a sage's or superman's character (爲己之學) and completed the methodology. Therefore the context from Confucius to Southern Song China Era is argued as a context of development and systematization of the methodology. In addition the fact that Zhuxi(朱熹) and his students had systimatization of the methodology with the publications of some important textbooks is also explained. The most stressed thing of this study is Yeoheon's Yeok-Hak-Do-Seol is just the text that succeeded them as the methodology of self-organization and had a special purpose of completion of the methodology not only with comprehensive items of practice but also intuition into the human's life and the world by his mastery of Yeokhak(易學). The viewpoint this study keeps is the Confucian methodology of self-organization is considered for the purpose of development and upholding the Confucian truth, and thus the methodology itself has been regarded as the necessary one that is the closest approximation to a pursuit of Confucian truth. According to this viewpoint we can observe the features of methodology of the pursuit of Confucian truth from the Yeok-Hak-Do-Seol. However the Yeok-Hak-Do-Seol has its purpose merely on a human being's self-organization but also on an enormous enterprise to make the universe peace or sustainability of the world. His stress on the enterprise shows that his methodology is not a merely repetition of the tradition of the Zhuzixue but a creative deveopment of the tradition. The other feature is that his methodology is systematization on the basis of Yeokhak, or the study of Yi-jing(易經). The main method he intensified is easiness and simplification that is the main point which he extracted from Yi-jing as the most important and necessary way of life.

Noju Oh Hui-sang(1763-1833) is one of the neo-Confucian scholars representing with Hong Chik-pil the Kiho-Nak School from the late 18th to the early 19th century. He did sincerely not only succeed theories of Kiho School originated from Yulgok, but also strengthened the main view of the Nak faction by clarifying the theoretical stance of it derived from Kim Chang-hyop. Not only he does suggest critical points of view against Ho faction in terms of Horak Controversy, but also criticizes heterodox account, which raised by an inner circle of Nak faction. In this vein, Oh established the neo-Confucian ways of realization of morality and ideal society by setting up his own points of view on mind and bright virtues that are followed by various issues of Horak Controversy. My paper will examine the values of Oh's account of Nature-Principle in the light of intellectual historical context by paying a special attention to his critical views of Ho faction. Oh's main idea is how to systematize practical foundation of realizing morality. Thus, he wants to theoretically explain both the practice of morality and the reality of pure moral mind in order to establish concrete practices of them in the real world. In doing so, he pays attention to mutual inclusive relationship between Principle and Matter(ki:氣). The mutual inclusive relationship between them can be exactly applied into the relationship between mind and Nature. So, the realityof moral principle explicitly implies the pure goodness of moral agency. Furthermore, his elucidation of logical relationship between mind and Nature and its values via the ontological understanding of them is to set up a system of cultivation, i.e., realizing practical foundation of pure moral mind. In conclusion, we can evaluate that Oh's account of Nature-Principle, at least, aims not only at establishment of moral agency and its reality in a theoretical dimension, but also at a guarantee of their realization in the world.
