There are many ways to know the social and cultural level of each country. Among them, a museum are not only the best place to understand the history, the life style and the culture level. The most important constituent, which museum architecture has, are visitors, exhibition and communication between visitors. Exhibition space composition is the one of important things in museum architecture, and it's essential to show an intent of exhibition to visitors. This thesis has the purpose to provide the basic material through analyzing exhibition space composition and exhibition method of the theme museum and understanding the relativity of them so that the new theme museums can be designed in the Tight direction. So I chose the independence museum that opened within recent 10 years, finally middle & small size's theme museum were selected. The results from the case study are as follow. Firstly, the exhibition space unit of basic type and center-hall enter type had a one-way for gateway and used the exhibition of three or four faces. The exhibition space unit of around tile center-hall type and guidance type had the separated gateway and used the exhibition of one or two faces. Secondly, the exhibition method of selected museums was divided into the wall face type and the island type. The exhibition method of two faces mainly used in guidance type caused complicated visitor circulation. In that case, it seemed to be good that two walls were used alternately. Thirdly, there were visual type, audio-visual type, handling type and experiential type in the method of exhibition. The former two types were used mostly, and the latter two types were rarely used. Fourthly, the wall face type was inefficient for exhibition because given walls were supposed to be used. Therefore, it was more effective to use the wall face type and the island type together.

This paper focuses on configuring a user-friendly system of LED systems by applying improvement measures such as gamma correction, non-flicker, and driving noise removal using MCUs and LED drivers. As a result of the experiment, the 22kHz PWM mode of the LED driver generated noise outside the audible frequency range, making it practically imperceptible to users. The appropriate pull-up resistor values within the normal operating delay ratio of 5% were found to be 1kΩ to 10kΩ for the 3kHz PWM mode and 1kΩ to 2kΩ for the 22kHz PWM mode. In addition, gamma correction can be optimized for nonlinear human visual systems to express accurate contrast and as a result, it is expected to develop an LED system that can be expressed more naturally and accurately than conventional LED systems and improve users' visual experience.

Art is the product from the combination of politics, economy, and social and cultural aspects. Recent development of digital media has affected on the expansion of visual expression in art. Digital media allow artists to use sound and physical interaction as well as image as an plastic element for making a work of art. Also, digital media help artists create an interactive, synaesthetic and visual perceptive environment by combining viewers' physical interaction with the reconstruction of image, sound, light, and among other plastic elements. This research was focused on the analysis of the relationship between images in art work and the viewer and data visualization using sound from the perspective of visual perception. This research also aimed to develop an interactive art by visualizing physical data with sound generating from outer stimulus or the viewer. Physical data generating from outer sound can be analyzed in various aspects. For example, Sound data can be analyzed and sampled within pitch, volume, frequency, and etc. This researcher implemented a new form of media art through the visual experiment of LED light triggered by sound frequency generating from viewers' voice or outer physical stimulus. Also, this researcher explored the possibility of various visual image expression generating from the viewer's reaction to illusionary characteristics of light(LED), which can be transformed within external physical data in real time. As the result, this researcher used a motif from Piet Mondrian's Broadway Boogie Woogie in order to implement a visual perceptive interactive work reacting with sound. Mondrian tried to approach at the essence of visual object by eliminating unnecessary representation elements and simplifying them in painting and making them into abstraction consisting of color, vertical and horizontal lines. This researcher utilized Modrian's simplified visual composition as a representation metaphor in oder to transform external sound stimulus into the element of light(LED), and implemented an environment inducing viewers' participation, which is a dynamic composition maximizing a synaesthetic expression, differing from Modrian's static composition.

One of the major functions of rural extension services is to transfer agricultural technologies and information, and advanced new agricultural techniques developed by research institutes, which are meaningful when they are transferred to farmers for practicl application. Information materials can be transferred in the form of newspapers, radio and television broadcasting, printed materials, audio-visual aids, and public communication networks. Agricultural information systems in the era of localization should be oriented toward county extension services, and the following points should be emphasized for more effective dissemination of agricultural technologies : 1) Central organization of the Rural Development Administration should put more emphasis on the production and dissemination of agricultural information to support activities of extension agents at the county level. 2) An Agricultural information center should be established for more effective collection, analysis, processing, production and dissemination of various agri-related information. 3) An advanced and unified network system should be adopted for more accuate and rapid information flow throughout the country, and reinforcement of manpower and facility at the county level should be emphasized for more effective dissemination of agricultural information.
