Dynamic context is considered as a source for intuitive understanding on the calculus. The relation between the area under time-velocity graph and distance is the base of the dynamic contexts which are treated in the integral calculus. The fundamental theorem of calculus has originated in dynamic contexts. This paper investigated the fundamental theorem of calculus via the relation between the area under time-velocity graph and distance. And we analyzed mathematics textbooks and the understanding of students. Finally we suggest some proposal for the teaching of the fundamental theorem of calculus.

The purpose of this study is to explore the differences in aesthetic experience according to the level of audience participation. Flow experience and aesthetic distance were utilized as proxies for aesthetic experience. A total of 70 undergraduates participated in the experiments of this study. In terms of flow experience, active participation groups were found to have relatively greater flow experiences compared to contemplation groups and passive participation groups. However, there was no difference in flow experience between the contemplation groups and the passive participation groups. In light of aesthetic distance, which means psychological distance, people in active participation groups were found to have a closer psychological distance from artwork than those in contemplation groups and passive participation groups. Also, those who belonged to the passive participation group showed a closer psychological distance than the contemplation group. The results of this study provide artists and art organizations with implications for enhancing audience attraction as well as the completeness of artwork.

The purpose of this thesis is to figure out the mechanism that how can be shown the aesthetic distances of novel in the film. At discussion of the view point, novel can be told by two factors which are 'who is teller' and 'who is watcher' but in the film, novel's narration is divided into visual point and auditive point. And I will consider the phenomenon on the part of this difference. Next, I will argue about difference between novel and film from the Park Jongwon's aesthetic distances which interpreted Lee Munyeol's work. This thesis is going to observe that how the film adapted three types of view point and how that related the subject of the original novel. For this thesis, I tried to track 'the distances' between figure and identity, and reader and author. Also I did approach that how can be accepted the problem of 'aesthetic distance according to identity' based on this novel in the film and novel's text by reader. This study make a proposal or analysis to the differences between novels and films in terms of narrative point of view. Although it is shown by dividing into each chapter in novel and on connectivity in film, this paper finds out that both film and novel are shown the subject of reader's difference of the view point about 'author and director's identity'.

As a theoretical background for this research, the literatures which focus on the rationale of teaching and learning of connecting with mathematics and science in calculus were investigated. And teaching and learning material of connecting with mathematics and science in calculus was developed. And then, based on the case study using this material, the research questions were analyzed in depth. Students could understand mean-velocity, instant-velocity, and acceleration in the experimenting process of constant acceleration movement. Also Students could understand fundamental ideas that instant-velocity means slope of the tangent line at one point on the time-displacement graph and rate of distance change means rate of area change under a time-velocity graph.

지난 30년 동안 서구과학계는 엄청난 변화의 물결이 일어났다. 과학은 무미건조하고 어떤 감동도 주지 못하며 예술과는 거리가 멀다고 생각해 왔다. 그러나 과학과 예술과 함께 자연을 경험하는 두 가지 상호 보완적인 방법의 하나로서 최근 자연 속의 복잡한 모양이 내재하는 규칙을 이해하려는 프렉탈 과학을 통하여 과학과 예술간의 실제적 접목이 여러 가지 방향으로 시도되고 있다. 우리의 미적 감각은 자연에 나타나는 질서와 무질서의 조화로운 배열에 의해서 영감을 받는다. (중략)

This study aims to interpret the current landscape design of the place and landscape of memory, such as post-industrial parks and memorials that have an old, aging appearance from an aesthetic perspective. The objects of the study are large parks and open spaces that have collective memories for visitors. Visitors' aesthetic experience from these places and landscapes of memory could be explained by aesthetic concepts such as the sublime, nostalgia, and melancholy. Because these aesthetic concepts are associated with past traumas, visitors may be affected morbidly. However, due to the capability of the media to form an aesthetic experience when visitors visit a given place and landscape, visitors can autonomously adjust the distance to the place of memory and gain an aesthetic experience. The aesthetic experiences through the sublime, nostalgia, and melancholy are based on temporality and irreversibility. Temporality here refers to a characteristic of memory, and time in the place and landscape of memory and is based on the irreversibility of time, as time cannot go back. Both the place memory and the memory that is recalled from the combination with visitor's past memories and knowledge are two major factors involved in the construction of the aesthetic experience in the place and landscape of memory. The results of the present study are meaningful in that this study presents a framework for a better understanding and use of both the place memory and appreciators' memory in the design process of a place and landscape of memory and also criticizes a materialistic approach that fails to take into account the visitors' memories.

This study is about investigating students' recognition and expression on relationship of 'time, distance, speed' via teaching experiment. In this process, students showed not only a change in perception of the relationship of 'time, distance, speed' but also recognizing the average speed as a viewpoint of the slope of the line connecting the end points of the interval in the distance function as well as another way of perceiving average speed of a height of a rectangle. In this process, the study shows the scene of expanding the relation of 'distance = time ${\times}$ speed' to 'distance = time ${\times}$ average speed', and also the student who makes the continuous reasoning shows the possibility of constructing a new function that can explain the change of the primitive function by allocating the average rate of change to the interval. Although this study was conducted with a limited number of students, this study suggests some implications through the observation of relationship of 'time, distance, speed' the students'. We hope that these results will be the starting point for various studies for constructing the integral learning model in the future.

Existing outdoor lighting evaluation methods for the city beautification at night, the measurements are limited by one point to analyze the photometric data. However, this methods could not represent the diversity of photometric result from the distance. This study aims to propose the new outdoor lighting evaluation method of structure surface luminance in accordance with the measuring distance. For the purpose, the field measurement and simulation of an illuminated structure were conducted by CS-100, Digital Photometry Instrument ProMetric 1400, and the Lightscape v 3.2 from the distance of 100[m], 300[m], 500[m]. The result shows that evaluation of the surface luminance by the distance should be measured from about 100[m] of an illuminated object for getting the familiar result from computer simulation.

Movie research in the 1980's structuralism looks tendency to escape director or text research and analyze spectator or inspection action. These post-structuralist divert interest by analytic convention of spectators in analysis by director's intention or text type correctly. There is the age that spectator, inspectional action and inspectional subject weighs more than director, work and text itself. But, inspection of movie can be person's enemy by director's narrative strategy or spectator's analytic quality that depend on a text and spectator and their interaction usually, and only method to acquire universality chooses full analytic discourse to principle. We should be structured by symbol system that the event is consisted of movie language to reappear the event through narrative in movie and this symbol system, director's narrative strategy can cause fixed esthetic distance between spectator. Researches to analyze this distance need to keep universal validity as much as being accepted by effort to gap with director and spectator. Therefore, narrative poetry that I analyze movie narration style by 'narrated' and unit of 'narrating' and study the form and function so-called, is going to follow narratology's access method. The consistent argument of this narrative poetry is that story is consisted of the events and these observe to structured thing by unit that is sequence through arrangement with the other event that adjoin in the event. Also, director need consensus with spectator to reappear connection of this event logically and it is thing which this reappearance form can be done characteristic by narrative strategy in directing. I am going to try narrative structure analysis of movie by narrative that is connected at structure of the event and 'narrating-narrative acts' that is interested in way to reappear this story to spectator hereupon. Of course, at process of research, Roland Barthes and his followers wish to apply 'narrative function' and concept of 'narrative acts' that prefer from time to time.

Postmordern style showed in contemporary fashion is various. Specially, street style begins from teddy boys, mods, hippy, skin head & popular fashion. They are come from mass culture. Mass culture dominated in many ways in modem society. In music, cinema & other plays we can read of youth. Street style includes youth culture about their fear and resistance and their passion. We can see kich in aetheics of street style as it was showed in mass culture. They are as follows. ${\cdot}$ Wit and sympathy expressed in primitivism. ${\cdot}$ Sensuality expressed in erotism like shows in works of Vivian Westwood & Zandra Rhodes. ${\cdot}$ Fantasy expressed cyber & psychidelic fashion.
