Nail art, which has been popularized recently, has increased convenience in the direction of nail art design harmonized with clothing and the increased interest and usage of nail art decoration. This study set out to propose practical planar and three-dimensional nail art designs in harmony with modern clothes by applying trimmings common in 18th century women's clothing, which used a variety of attachable decorations. As for the methodology, the investigator examined theories in previous studies, literature, and analyzed the types of trimming in female portraits from the 18th century at the museum at the Palace of Versailles in France. Planar and three-dimensional nail art designs were created for each of the top three trimming types- braids, laces, and ribbons, which were identified through analysis. The study applied the trimmings of the 18th century women's clothes to nail art design and had the following results: First, the top three trimming types were identified based on the analysis of the 18th century portraits. They were then used as motifs in the production of planar and three-dimensional nail art designs. The results show that the motifs of the clothes trimmings were fit for and had practical possibilities for expression in nail art designs. Secondly, diversity and the expansion of ideas in the study of nail art design were promoted. In addition, elements were increased to have mutually complementary effects with clothes. Finally, the study made various attempts at nail design methods by adopting a range of nail art expression techniques including hand painting, 2D & 3D art techniques, and using planar and three-dimensional nail decorations, thus proposing a positive direction for the organization of a curriculum to make use of 18th century women's clothing motifs in nail art education.

We design, fabricate, and measure a MIMO antenna system mountable on a small PCB (such as UMPC). The proposed antenna system accommodates three radiation elements on the PCB area of $40mm\;{\times}\;100mm$. Two of them employ a slot type and one uses a modified monopole with an inverted L shape expecting high isolation and polarization purity. The bandwidth of each proposed MIMO antenna ranges from 80MHz and 200MHz at the center frequency of 1.8 GHz. The isolations between ports have been found to be greater than 10dB over the interested frequency band. Besides, the proposed MIMO system has been evaluated in terms of ARC(Active Reflection Coefficient, TARC(Total ARC), correlation, MEG, and etc. The envelope correlation is calculated to be much less than 0.04 and the ratio of the mean effective gain(MEG) between the antennas is found to be close to unity.

In this paper, performance evaluation of mobile access layer for multiple-input multiple-output (MIMO) MultiCarrier(MC)/CDMA 16 QAM system is considered to mitigate multiple access interference and enhance system channel capacity in Rayleigh wireless fading channel. Traditionally, multi-path is viewed as an undesirable feature of wireless communications. Therefore, diversity and adaptive array schemes are proposed to mitigate its effects. Recently, to increase the spectrum efficiency and the link reliability, MIMO schemes is devised to exploit multi-path in a scattering wireless channel. In particular, the channel capacity of MIMO-MC/CDMA 16 QAM system is evaluated according to Eb/No, Mc, p. From the results, in order to improve the channel capacity, the signals at various elements must be uncorrelated. And if the paths are correlated due to inappropriate spacing or mutual coupling effects, the channel capacity of MIMO-MC/CDMA 16 QAM system becomes substantially smaller.

Since the year 2000, the need for an improvement of archival descriptions has been an increasing issue, due to the growing usage and amount of archival materials. Unlike the development of descriptions for paper records, however, the technological development and research for moving image descriptions has been limited due to its diversity and specificity. This research investigated the current status and the specificity of the moving image descriptions and also examined major international archival description cases. In-depth interviews with archival professionals were also conducted. Based on the findings, this study suggested the need for redefinition of and continuous research on the fundamental values of moving image information, moving image description and management based on digilog view points, the development of user-centric description and search aides, the creation of moving image values using a relevant information management system, and the improvement of moving image description elements throughout the life-cycle of the material.

The purpose of this study is to investigate the basic historical characteristics and its modern trend of Torajan traditional housing architecture in Sulawesi Province, Indonesia. The Toraja culture belongs to the cosmological culture with Cosmos centric characteristics. A traditional house, being called 'tongkonan' in Toraja region, is more than just a structure, representing the symbol of family identity and tradition. The Torajan architecture is a combination of the myth and cosmos, also regional conditions. With a short description of the general conditions and spiritual values of the Toraja, this paper explains the space-composition, the stylistic characteristics, the ornamental elements, construction, and its modern trend, etc. In general, it is raised on stilts several metres high, with a dramatically boat-shaped roof. Village layout varies according to size. The houses are arranged in a row, side by side, with their front gables facing north. Each house stands opposite its own rice-barn. The houses with their oblong ground-plans, built on piles set on stones. The interior is divided into three or four rooms, having few window. The houses are embellished with carving and paintings, and the facades display engraved and painted geometric and figural designs. The most frequent motif is the buffalo head, ranging from the realistic to the highly stylized. The Torajan traditional housing have experienced radical changes during the Modern period. In spite of the popularity of new modern house-styles, the traditional architectural style is often now constructed as an icon of Toraja identity. This paper will be helpful for understanding regional diversity of the traditional housing in Southeast Asia.

In radio communication technology, SDR(Software Defined Radio) technology is emerging as a trendy technology for future. SDR is expected to change existing radio systems including central hardware. SDR is equipment that wireless parameters (frequency, modulation, additional service, power level, receive sensitivity, etc.) are controlled by software. In the world, equipments using the new technology are spreading. Not only equipments being imported but also local manufacturers are making this equipment, developing software and offering upgraded service. In the future, as SDR spreads and users choose the service, diverse equipments will be developed through competition and individual development. This diversity of equipment and services will introduce problems in compatibility and interoperation issues. So the government will have to make technical standard for SDR service and will have to make theses standards available to users and manufacturers alike. Therefore I am investigating the elements that can be used to establish these standards.

The tendency of formalization in Contemporary Architecture deeply relies on the thought of Western Philosophy, which emphasizes the art of image perceived visually but ignores the body and perception of a human beig who uses the architecture and lives in it. On the contrary, Merleau-Ponty asserted long time ago that the world and the body are inseparably related to each other. The phenomenology is important in Architecture, since the center of thought should be taken back to the human body if a artistic meaning can be obtained by Architecture. From this point of view, the meaning of Contemporary Architecture can be renewed by the phenomenological idea of Merleau-Ponty as a means of expanding thought that overcomes the limit of formalization in Contemporary Architecture. This research aims to ream from Steven Holl's work, and show the Architectural elements that are used for preceptual experience of phenomenon and the function of those element sin Architectural space of his works. The result of study on about the phenomenal light and water in Architectural space of Steven Holl is as follows; First, in perceptional experience of phenomenon, time is an important element, which is successive and make a field that cause perceptional experience. Second, light, as a phenomenological element, acted as a means of expressing the comparison and change of light and shadow in Architectural space and showing the change of color by the diversity of time in inner space. Third, water, as a phenomenal lens, not only acted functional but also functioned as an element of sensual experience in Architectural space. It acted as an image containing time, space, just like a mirror that reflect the environment.

The purpose of this study is to examine the recent various developments of men's fashion by analyzing how exotic tastes were presented in men's modern fashion from 2001 to 2010. For this purpose, a researcher reviewed relevant studies to identify the styles of exotic tastes that were reflected in men's modern fashion specifically in Chinese, Japanese, Indian, East Asian, American, North American and South American styles. Findings of this study is summarized as follows. Main examples of men's modern fashion were found in Chinese-style apparel such as the magwae, queue, coolie hat and the Mao jacket. The Kimono and the samurai robe, both of which best represent Japanese apparel and the Japanese traditional patterns also had an influence on men's modern fashion Indian style clothing such as dhoti, veshti and lungi which cover the lower body, vajani as loose trousers, kurta of full-over tunic form and turban also had an effect as well. The men's modern fashion is also impacted by Middle Asian styles that includes the thobe, sirwaal, futah, which is sort of a skirt that is long enough to cover the calf and whose front parts overlap each other, turbans and the hempen hood which is fixed with the agal. Exotic elements such as animal skins, body painting, tattoos and head dresses found in African styles can also be found in men's modern fashion. Parts of North American style influence come from the applications of Indians' costume and head dress. The surveyed men's modern fashion of the South America style was represented by the applications of natives' costume and Andean tunic, loincloth and shawl. In all of the exotic styles found in men's modern fashion, historicity, eclecticism, aestheticism and nature-orientation are implied. They are the source of inspirations that promote changes and diversity in men's modern fashion.

The "Rurban" Design is a design concept that can actively preserve and embrace natural terrain and rural resources in an effort to continuously enhance a city, and restore the community that collapsed due to industrialization and unplanned urbanization. The concentration of Seoul Metropolitan area in Korea and the destruction of rural areas and localities caused by the urban sprawl have become a difficult problem for urban development after industrialization. The development of unbalanced growth and the environmental damage remain as issues as well. The tradition and diversity restoration of the New Urbanism paradigm, which was presented in the latter half of the twentieth century, has been an alternative plan for a big city that had experienced industrialization and urbanization at an early phase. However, there is a limit of application to European and North American cities. The philosophical concept of "Rurban Design" is to apply the use of rural elements more directly, and to outline resource conservation, proper consumption, and suitable scale. In all considerations, this will be a practical strategy to complement the limitations of New Urbanism with its design capacity that maximizes the characteristics of the region.
