Considering that rural village had evolved through a long-sustained effort of harmnization with nature, there should be the wisdom not only to reflect the level of rural resident's housing demand, but also to conserve the traditional characteristics of high-valuation in the modern rural housing. In Korea , standard design proposals of rural houses had been made public three times ; in 1972 , 1984 and 1995. so , firstly, this study analysed the inner-space layouts of design proposals mentioned above, from which changes and problems in the past housing design were derived. And also, through, the positive acceptance of residents' opinion living inthe houses built by standard design proposals in 1970 ~1980's, improved design principles and an alternative model were proposed , finally. The inner-space structed of standard design proposals in 1970s was originated from small-scaled and low-priced one, basically under the " open system". In 1980s, the basic design principle changed to the 'closed system' in which the living room being the focus of indoor family life, and , in 1990s, progressively, therural housing developed to the high qualified type by the spatial enlargement and with increased equipements. However, this structural change of rural house brought about the problem of functional separatioon between farming and daily living activities. In details, limited spaces of multipurpose spaces and sanitary facility would be mentioned as problems for improvement. conclusively in this study, newoly arranged "open system" was recommended , as a basic design principle for theinner space structure formation of rural house, which easily links the constituent inner-house spaces to outer one. Based on this principle, the detailed design criterial was proposed as follows ; 1. The living room be directly linked to the front-yard and centrally placed, the addtional space of which could be secured for the special family events by the flexibleuse of its adjacent room or by the housing of male quarters(separated from main building quarter). 2. The kitchen also be directly linked to side-yard and to livng room , for the convenience of farming activities and the shortening of path flow housewife. 3. The expanded toilet-and-bathroom be placed in the directly connected left-hand side to the living room and also be allowed access through multipurpose spaces to out door. 4. The multipurpose spaces be directly connected to the kitchen and the toilet and-bathroom , of which function would be for undressing of working clothes, quickwashing and ordinary working.nd ordinary working.

The purpose of this study is to research on usability of Seoul Bike focusing on seoul citizens over-50s. Before the test, I researched Seoul Universal Design Guideline's background, purpose, principle and range through literature review. Then I did two tests based on re-establishment of the existing principle to fit the public service. First, I have noticed that using the service through an application was difficult for seoul citizens over-50s even if they have NEEDS for using Seoul Bike according to the survey. Next, I drew the result from User Task Evaluation Analysis. Due to the low app usability(the main point of the service) and accessibility and usability status was rate low, but the overall service process was comfortable and convenience. I expect this study will be a good resouce for public service design.

Elementary schools in Korea need to create an environment for integrated education and transform into school facilities that are central to the local community. This study assessed the level of universal design application in the physical environment of elementary schools based on the seven principles of universal design in order to create an environment in which all users, including elementary school students, can access and use school facilities equally. For this aim, field research was conducted on 243 elementary schools, and facilities with low application level were analyzed. As a result of the analysis, in order to apply the principle of 'flexibility in use', the rotating handle on the side of the toilet, which is used by the wheelchair user in the way the toilet is accessed, must be installed in a top-to-bottom rotational manner. In order to improve the applicability of the 'low physical effort' principle, it is necessary to select land and apply the plan from the beginning of the design.

Generally a return current plane(RCP) of high speed digital and analog part is partitioned. This is achieved in order to decrease the noise interference between subsystem in PCBs(Printed Circuit Boards). However, when the connected signal line exists between each subsystem, this partition will cause unwanted effects. In a EMI(Electromagnetic Interference) point of view, the partition of the return current plane becomes a primary factor to increase the radiated emission. Component bridge(CB) is used for the way of maintaining radiated emission, still specific user's guide doesn't give sufficient principle. In a view point of EMI, design principle of multi-CB using method will be analyzed by measurement. And design principle of noise mitigation will be provided. Generally interval of multi-CB is ${\lambda}/20$ ferrite bead. In this study, When multi-CB connection is applied, design principle of ferrite bead and chip resistor is proved by measurement. Multi-connected chip resistance$(0{\Omega})$ is proved to be more effective design method in the point of EMI.

Generally a return current plane(RCP) of high speed digital and analog part is partitioned. This is achieved in order to decrease the noise interference between subsystem in PCBs(Printed Circuit Boards). However, when the connected signal line exists between each sub system, this partition will cause unwanted effects. In a circuital point of view, RCP partition has a bad influence upon signal integrity. In a EMI(Electromagnetic Interference) point of view, the partition of the return current plane becomes a primary factor to increase the radiated emission. Component bridge(CB) is usecl for the way of maintaining signal integrity, still specific user's guide doesn't give sufficient principle.

Oullim is Vital principle Which allows humanity to continue its inherent culture. By proposing the evaluative authority of the creative significance of the invention of Hangul and its formation and superiority from the stand point of Oullim, I would like to focus on Hangul's creative significance on the grounds of 'broadly profound design'. The ideas of Hunminchongum's invention id based on the philosophy of Great Absolute. The philosophy of Great Absolute is natural phenomenon and metaphysical understanding of cosmology. But King Sejong could keep a good balance between identity and practicality. It is a high value of Hangul. The main idea of design is seeking for principle of nature and systematical vitality. King Sejong also put this main idea of design in practice for inventing Hunminchongum. In the process, Oullim appeared as an essential function for the Great Design.

0 and 1, two digits are principle and formality of digital media. Those principle and formality dwell in new media paradigm. They are founded on emergence of new types of space. As describing the relationship originating from the concepts of digital media paradigm and space and discussing their characteristics, this paper presents the grounds for a theoretical argument for formation of new space. The concept of virtuality which mimics and represents the real, non-linearity which resembles human system of thinking and sensing, and interactivity connecting the communication theory of human and machine, their properties form the important basis for emergence of a new aspect of space. The concepts of digital media paradigm divide a type of space into two properties. The first is a inner modality. The second is outer modality. Dynamic space implicates inner modality that humans internally recognize the sense of space through their body and sensing organs. Space is not sensed but sensing. Space has an organic nature through object's interaction. Space has an outer nature that is physically variable. Finally, space has properties of modularity that changes structure of space. For empirical basis of an argument, new media art that has architectural form and those spatial characteristics were compared and analyzed. This conceptual discussion for space which the formality of digital media is applied will be an important foundation for create space design.

The contact-less inductive power transformer (IPT) uses principle of electromagnetic induction. Generally, there were many methods to improve the transfer performance of traditional transformer. But, though the principle of IPT is similar to that of general transformer, it is impossible to apply the methods because of large air-gap. Consequently, many linear numerical formulas for analysis of performance and design of traditional transformer cannot be used in development of IPT. The concept of the IPT for vehicle like PRT(Personal Rapid Transit) system is suggested and some suggestions for power collector(core & winding) design of IPT to improve power transfer performance arc presented in this paper. The characteristic of power delivery with these novel methods in design is presented by simulation and examination.

The present paper is concerned with the design of distributed sensors and actuators. Strain type sensors and actuators are considered with their intensity continuously distributed throughout a continuous structure. The sensors measure a weighted average of the strain tensor. As a starting point for their design we introduce the concept of collocated sensors and actuators as well as the so-called natural output. Then we utilize the principle of virtual work for an auxiliary quasi-static problem to assign a mechanical interpretation to the natural output of the sensors to be designed. Therefore, we take the virtual displacements in the principle of virtual work as that part of the displacement in the original problem, which characterizes the deviation from a desired one. We introduce different kinds of distributed sensors, each of them with a mechanical interpretation other than a weighted average of the strain tensor. Additionally, we assign a mechanical interpretation to the collocated actuators as well; for that purpose we use an extended body force analogy. The sensors and actuators are applied to solve the displacement tracking problem for continuous structures; i.e., the problem of enforcing a desired displacement field. We discuss feed forward and feed back control. In the case of feed back control we show that a PD controller can stabilize the continuous system. Finally, a numerical example is presented. A desired deflection of a clamped-clamped beam is tracked by means of feed forward control, feed back control and a combination of the two.
