This study intends to observe how the essential elements of art have changed Human's sense of beauty extending over the whole lives as well as fashion through the investigation of Light and Rays which have played a important role in giving birthe to the new trend of art within the upheaval age of various cultures. The peculiarities of which Futurism of Italy and Rayonism of Russia including Impressionism have a great role in giving birth to a new trend of art by means of the development of science technology are like these. Impressionists looked for the origin of the subtle harmony in nature within changes of sun-rays. The special feature of Impressionism paintings was to express the line of vision diversely according to changes of light rather than to focus on the line of vision with clear outlines. Henceforth, Neo-Impressionism which developed Impressionism more systematically leaded changes of Light and Rays more systematically and scientifically and maintained Divisionnisme techniques which extends to lead towards color and light through dividing and juxtaposing color. In the early 20th century Futurists tried to express dynamism through the interpenetration of light and revive color and light through the division techniques of color and persist an artificial light like eletricity rather than a natural light. Rayonism of Russia which was ifluenced from Impressionism and Futurism maintained intersection of reflecting rays which emerges from an object of things more deeply. This pursuit of light and rays also light and rays also appears as it is in modern fashion. First, it is the fashion which applied sun-rays persisted by Impressionists and expressed colors which show differently according to direction of light. Second, it is the fashion design which re-analyzed what Futurists expressed artificial light and rays. Third, it is the design which expressed Divisionnisme theory persisted by Impressionists and Futurists into fashion as it is and was made of being divided the form of glittering light into small dots. Fourth, it is the fashion design which applied Rayonists'work which applied intersection of reflected rays. Like this, it is aproved that the pursuit of light and rays expresses as it is in modern fashion of the 21st.

Buddhism that has arisen in India began to build the Stupa to enshrine body and Sari of Buddha as an object of worship. The stupa existed as a tome of holy leaders even before the birth of Buddha, which was called stupa or tupa in the Sanskrit and the Pali, the ancient language of India. The stupa was renamed accordingly in each Buddhism transmitted countries such as Ceylon, Tibet, Nepal, Myanmar, Thailand and China and also reshaped according to their own formative style. But its original meaning and type are kept unchanged. The stupa was established in the 4 holy places including the birth place of Buddha, the place where Buddha found enlightenment, the place where Buddha preached for the first time, and the place where Buddha died. Thus, a pagoda to commemorate holy ancient places is called Chaitya, which became differentiated from the stupa in which Sari is enshrined. The stupa means Nirvana, the eternal body of Buddha, and also a place filled with teaching and preaching of Buddhism. It signifies the symbol of Buddha who escaped from the death and rebirth, to achieve complete extinction, i.e. parinirvana, and to reach ultimate eternal world, rather than simply means death. During the non-statue of th Buddha period, people built the stupa to embody Nirvana of the Buddha, and worshipped the tomb where body of holy saints was enshrined. On the other hand, they also sanctified memorial things such as tools that holy saints used, the Bo tree under which one achieved Nirvana, Dharma cakra that implied words, footprint that carried out mission work, and a way to reach to heaven.

MeLuhan's work has enormous power in the study of media theory. In Lee-Sang's works, we can find out the Macluhan's idea, "tactile" writing, which enhances more than one single sense, we-Sang's pieces, viewed as the origin of Korean concrete poetry, are being reconfigured in modern times. After publication, Lee-Sang's esoteric and complicated poem was considered as the result of schizophrenia. However, in the reconfiguring process, his continuously issued poems were reconsidered as a fraction of visual arts and analyzed as the substances of Korean dadaism and an attitude to challenge. But the real importance of Lee-Sang's poem is the extension of a sense; his poem is unbiased either by visual part or by emotional part, though one sense is extended to another sense. Now you will see the reinterpretation of we-Sang's world from the viewpoint of media, 'extension of senses'.

The Jindo is a Korean native dog, well-known for its hunting and guarding abilities. When he gives his devotion to one individual, he gives it whole-heartedly. He is not tempted easily and impetuous. The breed was not developed. but the dog retained their original qualities -loyal, alert, fearless, obedient, watchful, intelligent, energetic- to survive in the harsh environment of the Jindo island. The dog had been spread over the entire Korean peninsula from the time unknown, and the ones in the Jindo island, isolated until lately, survived and maintained their original characteristics. They are now spread over the entire Jindo County consisted of many islands, whence the breed name came. The Jindo comes in a variety of colors and color combinations, with the fawn and white colorings predominant. The dog is one of the Korean natural monuments, protected by law since early 1960s. The Jindo gained official approval by the Federation Cynologique Internationale as a hunting dog. Apart from the basic housetraining, the dog rarely gets training. Many people have attempted to preserve its pure bloodlines and original qualities. Today, there are a total of 10,356 Jindoes being raised over the entire Jindo County, and many more are kept elsewhere. A research into genetic characteristics of the Jindo is now going on, using the technique of isozyme electrophoresis. The Jindo Dog Breeding Management Center has been reinforced lately, and in addition to their routines, the Center is to work on the breeding of the Jindo. Efforts should be made in the future to produce stable, trustworthy Jindoes according to their proposed use and to modify their temperament in order to make it more widely acceptable as a pet and companion dog in the strangers home.

Capacitance versus voltage (C-V) curves of Ge-nanocrystal (NC)-embedded MOS capacitors with and without a single capping Al2O3 layer are characterized in this work. C-V curves of the Ge-NC-embedded MOS capacitor with the A12O3 layer are counterclockwise in the voltage sweeps, which indicates tile presence of charge storages in the Ge NCs by the tunnelling of charge carriers between the Si substrate and the Ge NCs. In the Ge-NC-embedded MOS capacitor without Al2O3 layer, clockwise hysteresis of the C-V curves and leftward shifts of the flat band voltages are observed for the embedded MOS capacitor without the Al2O3 layer. It is suggested that the characteristics of the C-V curves are due to the charge trapping at oxygen vacancies within a SiO2 layer. In addition, the illumination of the white light enhances the lower capacitance part of the C-V hysteresis. The origin for the enhancement is discussed in this paper.

An imaging method of seismic sources using time-reversal wave propagation is presented. The method is based on the time-reversal invariance and the spatial reciprocity of the wave equation. Time-reversal wave propagation has been used to image anomalous features of a midium in medical imaging, non destructive testing and waveform tomography. Seismogram is the record whose energy is propagated from the seismic source. If time-reversed seismogram propagates back into the medium, seismic energy is concentrated at the origin time of the event and at the source location. In this work, a staggered-grid finite-difference method of the elastic wave equation is parallelized for 3-D wave propagation simulation. With numerical experiments, we show that the time-reversal imaging will enable us to explore the spatio-temporal history of complex earthquake.

This study aims at examining the background and development process of Masan city after Koryo Dynasty, making a reconstructive map of Original Masan using the first registration maps made in 1912 and analyzing the urban structure of the Original Masan area. The origin of Masan city went back to Koryo dynasty. Around 1040 Koryo government placed an official shipping facility in Masan to transport the taxed grain to the capital city. After that Masan became an important port covering the southern part of KyungSang-Do. And the urbanization of the Original Masan began to bud after a shipping facility was again established by the Chosun Dynasty in 1760 and strengthened in the 19th century after the social standing system was broken and many peasants moved to cities as daily workers. In 1899 Masan was forced to be opened to foreign powers and they placed an international settlement distanced from the area(Original Masan). After this many Japanese advanced to the international settlement and further to the area. The advancement of Japanese brought a critical change in the urban structure of the area. Land was owned by Japanese and many modern sysytems were introduced such as modern buildings, new roads, railroad and modern factories. According to the reconstructive map of the area, 80.5% of land lots are less than $200m^2$ showing the size of each land lot is comparatively small. And Japanese occupied 31.5% of the land in the area. Their land was located on the stratigic points near the port and the center of commerce. The ratio of the road area to the whole land was around 14%, not so low for urban areas in that time. The reconstructive map reveals the exact coastline of the year 1912 erased now due to filling the sea and extending the land, Present Masan city has been developed having the Original Masan as its nucleus. The area has been always the center of urban activities for Masan city. Making an exact reconstructive map for the area and analyzing the urban structure of the area in 1912 is a very important work to understand Masan city wholy.

Numerical simulation is conducted to investigate aerodynamic force generation mechanism for the "figure-of-eight" motion of Dipteran fly, Phormia-Regina. Wing trajectory is referred to experimental result, which was observed from the tethered flight under freestream condition. Numerical simulation shows that the lift is mainly generated during downstroke motion and the large amount of thrust is generated abruptly at the end of upstroke motion. In the present work, vortical structure in the wake and the pressure field around the airfoil are examined to understand the generation of lift and thrust. Consequently, the lift generation is related with the leading edge vortex which is developed by an effective angle of attack. And the thrust generation can be explained by vortex pairing in the flow field and by vortex staying in the pressure field.

Numerical results from the "figure-of-eight" motion of Phormia-Regina in Part 1 indicate that vortical structure and vortex dynamics do play a critical role in lift and thrust generation. The aerodynamic force generation of insects' wing could be governed by aerodynamic parameters such as Reynolds number; kinematic parameters such as frequency, amplitude, and component of the figure of eight motion; and morphological parameters such as wing shape and the number of wing. In the present work, the effects of Reynolds number, reduced frequency and motion component are investigated in detail to clarify aerodynamic characteristics of insect wing. Through numerical results and their physical interpretation, the mechanism of aerodynamic force generation is presented more clearly. Rotation turns out to be the most important component in thrust generation and subsequent counterclockwise rotational circulation is closely related with thrust generation.

Recently $Li_{1.2}Ni_{0.2}Mn_{0.6}O_2$ has been consistently examined and investigated by scientists because of its high lithium storage capacity, which exceeds beyond the conventional theoretical capacity based on conventional chemical concepts. Consequently, $Li_{1.2}Ni_{0.2}Mn_{0.6}O_2$ is considered as one of the most promising cathode candidates for next generation in Li rechargeable batteries. Yet the mechanism and the origin of the overcapacity have not been clarified. Previously, many authors have demonstrated simultaneous oxygen evolution during the first delithiation. However, it may only explain the high capacity of the first charge process, and not of the subsequent cycles. In this work, we report a clarified interpretation of the structural evolution of $Li_{1.2}Ni_{0.2}Mn_{0.6}O_2$, which is the key element in understanding its anomalously high capacity. We identify how the structural evolution of $Li_{1.2}Ni_{0.2}Mn_{0.6}O_2$ occurs upon the electrochemical cycling through careful study of electrochemical profiles, ex-situ X-ray diffraction (XRD), HR-TEM, Raman spectroscopy, and first principles calculation. Moreover, we successfully separated the structural change at subsequent cycles (mainly cation rearrangement) from the first charge process (mainly oxygen evolution with Li extraction) by intentionally synthesizing sample with large particle size. Consequently, the intermediate states of structural evolution could be well resolved. All observations made through various tools lead to the result that spinel-like cation arrangement and lithium environment are created and embedded in layered framework during repeated electrochemical cycling.
