The roles of the characters of 3D animation Toystory3, which was released in 2010 and achieved worldwide success, can be classified into typical, simple and easy-to-understand roles such as hero, villain, princess, and assistant. However, the process, in which each character's role is finally recognized by the audience, is embodied in a very colorful and exquisite manner and makes the curiosity of the audience continue effectively. The stream of the diverse role changes of the characters of Toystory3 is represented through "visual rhythm of the lighting design" and such rhythm can be confirmed most clearly in the digital colorscript stage. This researcher analyzed the characters' role changes in the work based on Propp's folktale character analysis theory, and extracted the core scenes that lead to inference, doubt, performance, reinforcement by character in order to grasp how the audience gasps major characters' role changes. The visual differences of the lighting design, which the four core scenes of each character show, were represented in graph and analyzed, and the results showed that the changes that one character has constituted rhythmical, visual contrast gradually and the rhythms of each independent character achieve visual contrast and harmony each other like the voice part of polyphony. This researcher calls this "the visual counterpoint of character's changing" and derives the conclusion that a dual visual counterpoint is hidden in the character production of the full-length animation Toystory3. Along with this, this researcher proposes the production of full-length animation that actively utilizes constructive aesthetics.

In Korea, it is necessary to improve the performance of buildings with respect to the energy efficiency while improving the quality of occupants' lives through a sustainable built environment. During the design and development process, building projects must have a comprehensive, integrated perspective that seeks to reduce heating, cooling and lighting loads through climate-responsive designs. The aim of this study is to assess the optimal window-to-wall ratio of multi-rise residential units in the early design phase in Korea. The study analyzed the variation of annual heating and cooling energy load in two apartment prototype units located in Seoul city using different WWRs. The analysis was conducted using Autodesk Ecotect Analysis 2011 tool. The study found for total annual building load reductions WWR on the south and north face should be studied independently based on the room function. It also found reducing the WWR for bedrooms and windows on the northern façade resulted in reduced total annual building load.

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.

This paper reports the conceptual design process for a floating metocean data measurement system (FMDMS) for measuring wind information at sea. The FMDMS consists of three circular pontoons, columns, and a deck, which the LiDAR (lighting detection and ranging) is installed on. The dynamics of the mooring lines and motion responses of the FMDMS were analyzed using commercial codes such as WAMIT and OrcaFlex. One design criterion of the developed FMDMS was to maintain the motion responses as small as possible to enhance the LiDAR's accuracy. Starting with the preliminary design parameters such as the FMDMS's principal dimensions, weight, and important parameters of mooring system, we checked whether the FMDMS met the design requirements at each design stage, and then made modifications as necessary. The developed FMDMS showed a large pitch behavior for a small heave motion.

This paper presents the high efficiency and high power-factor power supply for LED lighting equipment. The proposed power supply is the single-stage power structure consisted of the full-bridge diode rectifier and flyback converter, and thus the power-factor correction and output voltage regulation are performed simultaneously using only one controller IC and one power semiconductor switch. Furthermore, the proposed power supply reduces the voltage stress and switching loss of main switch using the regenerative snubber, and it improves the system efficiency using the synchronous rectifier. The applied synchronous rectifier is the new voltage-driven type and its operation and construction are simple. In this paper, the operation principle of proposed power supply is explained through the operation analyses of its power-factor correction and main power conversion parts and the operation of synchronous rectifier is described, briefly. Also, a design example of the power circuit of 40W-class prototype is shown and the operation characteristics of proposed power supply are validated through the experimental results of the implemented prototype by the designed circuit parameter.

Recently, various applications for LED lightings are growing continuously due to their better performances such as low power consumption, longer life time, operation speed, controllability, high quality color rendering, and sustainability. However, in developing the high-powered LEDs illumination system, heat-sink problem is one of the important obstacle. In this paper, a heat-sink design with multi-layered structure for high-powered LEDs is proposed, which is composed of metal core PCB, heat-pipes, heat-sink plates, and fans. And also, in this paper, a design for LED controls using DMX512 protocols through RS-485 communications is proposed, which is considered as de facto international standard in LEDs illumination control and is widely used in landscape lighting and stage lighting. In this paper, LED control and its application techniques are introduced and the method of wireless remote control for main controller is proposed.

The audience of the performing arts enacted on the stage appreciate acting of the characters in a play to understand its plot, identify with the characters, and comprehend the message and subject matters of the play. Stage make-up in particular should assist audience in comprehending the story without overpowering or distracting the script. Stage make-up is a crucial means to visualize occupation, class, personality, and age of the characters. Thus it is an essential means in producing a high quality performance. The aim of the study is to examine character-emphasis make-up for a play by reviewing theories on the concepts and methods of the stage make-up. The methodology of the study was to analyze character make-up of the adopted play The Madwoman of Chaillot (La Folle de Chaillot) translated from the original French, as a case study. The technique and features of the character make-up of the play were examined, and functions of each factor of the character make-up depending on a role were also examined. The results of the study are as follows. The stage make-up for creating and expressing a distinctive personality of the characters in a play must integrate environmental factors external to a performance such as lighting and scale of a venue. Moreover the stage make-up must adopt and reconstruct internal factors of the play such as interpretation of the original work, subject matters, interpretation of the script, character analysis based on the discussion with a director, and design setting.

The concept of sustainable development to preserve natural environment through economy in resources and energy is gradually distinguished since environmental problems as a series of air pollution and global warming take place now. Building occupies more than 1/3 of energy consumption in the whole world. Energy consumption of buildings caused a quick increase in the amount of energy use by air conditioning, which has a lot of effects on exhaustion of fossil energy as well as an increase in environmental load. Therefore, this research intends to suggest characteristics and direction for the designing of acclimatization's housing through the case study on acclimatization's housing. Acclimatization's housing is designed to reduce building load from the designing stage unlike green home or low-energy apartment. Also, factors which are commonly applied to acclimatization's housing are applied complexly by design strategic factors of Heating, Cooling and Lighting. The applied design factors make effects mutually and complexly. In addition, design strategy showed different priority by designing direction.

A new and accurate expression to derive a window area is presented with a sequence for daylighting design using Daylight Factor Method process not in its classical point--by-point method but in lumen method as in artificial lighting design process to consider daylight in the early stage of a building design process. Accepting CIE Overcast Sky as the worst state with the lowest sky luminance, a user of a room can have more available daylight in his or her room. In the design process uniformity is checked to ensure reasonably even daylighting by comparing the depth of the room with the computed limiting depth. After these steps the shape and position of window is altered, of which the Sky Component of Daylight Factor under an Overcast Sky, SCo, is investigated and computed in Composite Simpson Multiple Integral so that a building designer or an analyst can choose the best shape and location that satisfies his/her taste and purpose of the room.

The performance-art costume is a tool for expression that can dynamically display the intention of a production. The purpose of this study is to examine the whole costume for performance arts targeting musical works, to which were added such elements as music, dance, and drama, among performance arts in several genres. This study aims to consider how the symbol contained in the costume was intended to be expressed by inferring a change in performance costume and character as the stage costume. Accordingly, the following research problems were established in this study. First, Which role does the costume play in performance art? Second, into which types can the performance-art costume be classified depending on the kind of performance art? Third, what is the expressive method for the performance-art costume? To examine the types of performance-art costume, the acting costume, the singing costume, the dancing costume and the rhythmic performance costume were considered. As a result, the performance costume can be seen to have been designed through the effect of a change in color by lighting, through the differentiation of character caused by excessive decoration, through the differentiation in material for free movement, and through symbolic expression.
