Purpose: This paper tried to understand the architectural philosophy of Laurant Beaudouin who is one of Neo Corbusian architects. They were in succession to Le Corbusier's principles of modern architecture, and developed his concept of modern architecture with their own creative architecture, and formed a big achievement in the contemporary architecture. As a representative Neo Corbusian architect, the design concepts and principles of Laurant Beaudouin were analyzed in relation of nature, light and space. Method: Three step study was conducted for the paper; Firstly, investigated significant his architectural characteristics as a neo corbusian architect in the point of view of plan libre, architectural promenade and light; Secondly, analyzed his architectural philosophy on light, gravity and color, Finally, deducted relation light and space through analysis 5 works of Beaudouin. Results: According to the results of the study, Laurant Beaudouin has greatly developed of Corbusier's principles and philosophy of modern architecture, and then, created his own originative architectural works by combining nature, light and space and presented architectural promenade with the change of time.

This study is intended to analyze the way of incorporating the effect of natural light into the architectural space design by Le Cobusier. The composition of modem architectural space is significantly different from that of classical architecture. Such transition is attributable to the change of tectonic method which was supported by the development of new materials and structural systems. In addition, the effect of natural light systems which is one of the main elements in architectural space has undergone significant changes in modern ages. Moreover, Le Corbusier introduces the new concept of natural light in his works. By bringing the above two trends together, this study analyzed the way how Le Cobusier applied light effect in his works. Specifically, findings regarding the 'traffic flow in the space' with the light, 'elevation effect' with the 'Brise soleil' in Le Cobusier's works were presented. And also the way of lighting the object in the space was presented.

The dome structure has been treated in two layers among the techniques that have formed the space in Baroque architecture and the light used to be manipulated to create the openness of space and the fantasy of atmosphere. Such an expression technique has influenced on the expression of space in the architecture of New York Five in the 1960s to 1970s and the concept of multiple space embellished with various layers has appeared in the architectural concept of New York Five; meanwhile, the common meaning with the technique of double layers and the ways of phenomenal expressions that have recognized the existence of space in the Baroque period has been achieved through the light, immaterial organism. It means that the existing concept of light limited simply to the plane elements of brightness and darkness has been treated as a formative element that has defined and adjusted the visual expansion and reduction of the space Itself and special existence and has been used as an element of the media of spatial structure. In addition, these elements have been treated as another solution for the emotional aspects of space. Therefore, this study compares the plastic and formative meaning of the Baroque architecture with that of New York Five in terms of the relation between space and light and examines them; in doing so, it will give a clue to understand various and new space expression techniques to many architects and space designers who have led modern architecture.

Space and figure are formed not by themselves but by the existence of light. It is important that plays a role as an intermediary of cognition which enables the formation of space and figure through Human's recognition in the process of design. Human perceive space and identity every basic form by the contrast of light and dark. The existence of light is very inclusive concept in the space, so space and form are completed by light. The change of based on time, place, and its amount acts as an important element Which can change the form of Space. In Space light doesn't work simply as light itself, but have a very close relation with Space, Form, Structure, Material, Color elements, Space is limited by physical form but human perceive space relatively by many other conditions, So same space can be experienced differently by the characters of light. Human can recognized and observe an object in the space as he processes information collected through light. In this process light make it possible for human to see the shape in space. therefore, the shape of space can get meanings when light exists. the space recognized by light is the mean that activates human activates in space.

The Pattern of Young Child-Mother Attachment and the Self-Concept in Young Children. This work sheds light on the patterns of chi1dren's attachment to their mother and the self-concept of young children. Ninety-two participants were selected from kindergarten and nurseries in the city of Taegu. All the children were from 3 to 5 clears old. The measurement instruments were the attachment story completion task, created by Cassidy, and the self-concept test, designed and used by Bently and Yeatts. The data was analyzed by using frequencies, percentages, independent-samples t-test, one-way ANOVA, and the Scheffe test. The study's major findings are as follows: First, in the area of young child-mother attachments, the most common pattern was a secure attachment. The percentage of insecure-avoidant attachment was similar to that of the insecure-ambivalent attachment. Second, in terms of gender, there were no significant differences in self-concept among young children. Third, the self-concept held by young children varied significantly according to age. The younger the age, the more positive was the self-concept. Finally, the self-concept of children varied greatly according to the pattern of child-mother attachment. Those children who were more securely attacked to their mothers evidenced a more positive self-concept than those children who were insecurely attached to their mother.

The optimum design of auto-catalyst needs a good compromise between the pressure drop and flow distribution in the monolith. One of the effective methods to achieve this goal is to use the concept of radially variable cell density. However, there has been no study of evaluating the usefulness of this method on light-off catalyst. We have computationally investigated the effectiveness of variable cell density technique applied to the light-off catalyst using a three-dimensional integrated CFD model. in which transient chemical reacting calculations are involved. Computed results show that variable cell density technique can reduce the accumulated emissions of CO and HC during the early 100sec of FTP cycle by 86.78 and 80.87%, respectively, The effect of air-gap between the monoliths has been also examined. It is found that air-gap has a beneficial effect on reducing pressure drop and cold-start emissions.

We investigated the effect of Science Writing Heuristic (SWH) on elementary students' concept formation and their retention. Also we explored the interaction effect of those with scientific attitudes. We developed mirrors/lenses lessons incorporating SWH. An experimental group of fifth grade students (n=25) had been instructed with SWH lessons for six periods while a control group (n=25) taught according to the normal science lessons based on the Korean national curriculum using teacher's guides published by the Ministry of Education. Results of pre- and post-test of understanding the concept of mirrors and lenses showed a positive impact of SWH on both male and female students. However, the retention effect after post-test revealed that SWH only had an effect on female students' scientific attitudes. SWH, therefore, could be an effective teaching approach especially on concept formation, retention effects by fostering female students' scientific attitudes.

An innovative safety concept for a light water reactor has been developed at the Korea Atomic Energy Research Institute. It is a unique concept that adopts both a fast heat transfer mechanism for a small containment and a changing mechanism of the cooling geometry to take advantage of the potential, thermal, and dynamic energies of the cold water in the containment. It can bring about rapid cooling of the containment and long-term cooling of the decay heat. By virtue of this innovative concept, nuclear fuel damage events can be prevented. The ultimate heat transfer mechanism contributes to minimization of the heat exchanger size and containment volume. A small containment can ensure the underground construction, which can use river or seawater as an ultimate heat sink. The changing mechanism of the cooling geometry simplifies several safety systems and unifies diverse functions. Simplicity of the present safety system does not require any operator actions during events or accidents. Therefore, the unique safety concept of PX can realize both economic competitiveness and inherent safety.

This paper presents an external light evasion method that rectifies the problem of misrecognition due to external lighting. The fundamental concept underlying the proposed method involves recognition of the differences between two images and elimination of the desynchronized external light by synchronizing the image sensor and inner light source of the optical touch screen. A range of artificial indoor light sources and natural sunlight are assessed. The proposed system synchronizes with a Vertical Synchronization (VSYNC) signal and the light source drive signal of the image sensor. Therefore, it can display synchronized light of the acquired image through the image sensor and remove external light that is not from the light source. A subtraction operation is used to find the differences and the absolute value of the result is utilized; hence, the order is irrelevant. The resulting image, which displays only a touched blob on the touchscreen, was created after image processing for coordination recognition and was then supplied to a coordination extraction algorithm.

The leading paradigm of dentistry had been focused on the rehabilitation treatment that identifies active caries, manages them surgically, and restores their original functions. However, changes in the external environment including the current disease prevalence require dentistry to have a paradigm shift. The new paradigm suggests the detection of caries in their earlier stages over the visual diagnosis of cavities, and the reversal of the incipient caries by non-surgical approach. For this to be achieved, a high-technology detection device recognizing changes in the earlier stages which can not he visually observed is needed. Development of early caries detection device has recently become a major issue in preventive dentistry on account of this need, and QLF(Quantitified Light induced Fluorescence) conspicuously stands out among the newly released devices. In this study, the fundamental concept of QLF(Quantitified Light induced Fluorescence) and the possible clinical applications of the earlier intraoral camera model as well as the recently designed digital camera model will be discussed.
