The development of idyllic housings, is in increasing growth in the suburban areas of Seoul, presents some critical problems such as in sufficient common open space and poor living condition, which are mainly caused by disorderly designed. Through comparing planning indices of idyllic housing, this paper aims to diagnose the condition and causes of those problems and to present some basic issues on improvement direction. The causes of problems can be summarized as the blind point in regulation system, the shortness of planning elements of a housing block which includes road systems and public facilities, and the mismatch of housing type with density, on which includes road systems and public facilities, and the mismatch of housing type with density, on which hereafter improvement suggestion should be focused. And this study suggest the simulation models on an ideal idyllic housing to be applied in our forthcoming idyllic housing of Korea, which can indeed become a generalized alternative to the livable idyllic housing.

This paper a new approach to the design of machine vision technique with a camera modeling that accounts for major sources of geometric distortion, namely, radial, decentering, and thin prism distortion. Radial distortion causes an inward or outward displacement of a given image point from its ideal location. Actual optical systems are subject to various degrees of decentering , that is , the optical centers of lens design and manufacturing as well as camera assembly. It is our propose to develop the vision system for the pattern recognition and the automatic test of parts and to apply the line of manufacturing. The performance of proposed vision system is illustrated by simulation and experiment.

This study examines the various types of consciousness about sexuality exhibited by girls' high school students. The analysis was carried out utilizing two subject groups with the first being academic course students and the second being vocational course students. A 51 question questionnaire was prepared based on a literature review and previous research. The questionnaire was developed based on the results of two preliminary surveys, a reliability test, and a correction. A total of 721 questionnaires were distributed to students of 3 vocational and 3 academic courses. The analysis of the results was carried out using by means of SPSS 10.0. The study generated conclusive findings about each groups' viewpoint toward sex, the actual condition of their relationship with members of the opposite sex, the passages of knowledge about sex, the content of current sexuality education at school and the ideal type of sexuality education. This study shows that the current standardized content of sexuality education is ineffective. Sexuality education at schools in South Korea has reached a point, where research for more effective sexuality education is required.

For CSLDV, the Chebyshev demodulation (or polynomial) technique and Hilbert transform approach have been used for mode shape reconstruction with harmonic excitation. In this paper, the Hilbert-Huang transform approach was applied as an alternative to impact excitation cases in terms of a numerical approach. The vibration of the tested structure is modeled using impulse response functions. In order to verify this technique, a simply supported beam was chosen as the test rig. With additional innovative steps which are the ideal-band pass filter and the nodal point determination, Hilbert-Huang transformation can be used for a good mode shape reconstruction even in the impact excitation case.

Reverse digital artery flaps were performed successfully to resurface the fingertip defect in 13 patients as noninnervated pattern and in 12 patients as innervated pattern from March 1993 to February 1996. No loss of flap in this series was noted. Refinements in flap design and surgical technique resulted in favourable functional and ethetic results. The average two-point discrimination of the reconstructed fingertip was 7.2mm and 4.5mm in the noninnervated and innervated flaps, respectively. This flap is an one of the ideal and reliable option for reconstruction of fingertip defects.

As inexhaustible clean energy, solar energy will be the most ideal green energy in the 21st century. The effective method to convert solar energy into electrical energy is by solar photovoltaic power generation technologies. LED Emitting Diode is a kind of component which can transform electricity into visible light. As the smart current control system for photovoltaic street lights, the proposed system has improved the battery charging and discharging mechanism to extend the lifespan and effectively controls the LED discharge current according to battery charge state and lighting.

This paper is pre-stage for getting EGI which can be used for modeling of an object. It discusses the construction of the vision processing system and its algorithm for getting needle diagram from tie object image. We realize the algorithm with monocular camera system, using Reflectance Map theory and photometric stereo method. We can calculate the surface normal at any point in the image if we take multiple images at the different lighting conditions. From the 3 images taken from different lighting conditions through the experiment, we get the needle diagrams of the sphere and the object. We confirm the validness of the surface, normal acquisition algorithm comparing the experimental needle diagram with the ideal one obtained from the surface normal of the known object.

This paper proposed a simple and helpful analysis model of voltage variation in order to predict the voltage variation at PCC (Point of Common Coupling), when a wind turbine is connected in an isolated grid. The PCC voltage flucuates when the wind turbine outputs active power to an isolated grid. This voltage variation is proportional to the product of the line impedance from the ideal generator to the PCC and the wind turbine output current. And It is different according as where wind turbine is connected. To solve the problem of voltage variation, this paper proposed the reactive power control. To verify the proposed analysis model, this paper utilized PSCAD/EMTDC Simulation and the field measurement data of the voltage variation during the wind power generation.

In the middle of that a information form is being formlessly changed to diverse deirections, a design and a space as physical consequence show not only a allegory but mutually relational charicteristic meaning a nonboundary and nonlinear form by development of modem digital culture. Following development of the modern digital culture, a design and space which are physical results, show a point of correlative specificity, allegory, nonlinear and nonboundary, Not only a design and culture but also various circles handle a hypertext as a representative pivot in this change. this has same contexts as rhizome possessing a asignifiante and nomadic characteristic said by Felix Guattari and Gilles Deleuze. An ideal of rhizome space shows historical decisions, unexpected accidents, a concepts, an individual. a group, social compositions above an contrifugal exterior force, This study examines into surroundings designed by a hypertext and rhizome through a case accordingly and infers an ultramodern characteristic in conventional precognition with synthesizing a peculiarity of the digital generation space.

How to express movement in animation is one of the most important elements which form a work. An Interaction of the expression of a movement and the timing is a basic element which we need to understand and create an animation as a visual art. At this point the timing is an amount of the time required to move object or characters. This paper clears up the fundamental principle of the timing in stop-motion animations and shows Ideal timing methods by comparisons and experiments of the timings which change on a camera's angles.
