The aim of this study is to review phenomenological characteristics in Alvaro Siza's works through his design intention, methods and results. As a Portuguese architect, his personal and local background as well as pursuing the essence of architecture made phenomenological characteristics of his works. The emphasis of the placeness of site and the existence of architecture has close relationship with Heidegger's concept of dwelling and the role of architecture. Although Siza has maintained white plat plane of interior space which is one of features of modern architecture, he provides dramatic and dynamic experiences of space using curved and acute angle of plane in his latter part of works. Another his phenomenological nature of buildings is a striking display of space and light which is remarkable especially in his museum designs. He made this character in adopting various shapes of double ceilings, openings and their combination with natural light which he always emphasizes. As a result, Alvaro Siza's phenomenological characteristics comes not from clear architectural or philosophical theory but from continuous practice based on pursuing the essence of architecture.

To design and construct a museum of art involves the interest of artists, architects, curatorship, management, and local government. More than this direct relationship, museum obliges the public a mission of delivering genuine public experience through art and architecture. However, most of Modern and contemporary architecture has not delivered genuine public experience of integrated art and architecture. Conceptual message of art and perceptual architectural exhibition space has not been integrated easily. Picture frame canvas initiated this schism and institutionalized museum management hampered the creativity of artists. This schism was overcome through artists' questioning of museum culture and creative works that embrace work and its environment. In contemporary culture, installation art and media art necessitates a new museum format which needs not only exhibition, but laboratory and interface space with viewers. This paper will regroup the existing museum according to its use and strategy, and reinterpret progressive museums that fosters young artists, and more than this, will introduce successfully established museums for new forms of art, which are equipped with versatile exhibition spaces, innovative interface between works and viewers, and own laboratory that can produce works of art. These examples will envision a creative method of art and architecture production that can achieve genuine public experience.

School is where students spend a lot of time. However, it is made up spaces which have got no consideration for students. Public buildings, such as schools, were designed by experts, not by users, while the opinions of users were reflected in a small part. As a result, school has become an uncomfortable place for students. User participation design has been proposed as a way to improve it. Recently, in designing schools, user participation design called "School Space Innovation Project" has been carried out actively and many kinds of guidelines have been suggested in project. But because it is unsystematic, In fact, it is hard to apply on site. Comparing and analyzing various User Participation Processes to figure out the similarities and differences is the purpose of this research and we want to suggest the result as a data that can be used as guidelines for project related to User Participation Design.

One of the most important matters in keeping membrane structures in healthy condition is to maintain the proper tension distribution over the membrane. However, it is not easy to know the real stress level in the membrane quantitatively after completion of the structures. Authors suggested measurement method that can measure membrane stress using sound wave, and have been holding experimental tests of membrane stress measurement that used the sound external excitation with sine wave and white noise. The concept of the method is the fact that measurement of resonance frequency by vibrating membrane having rectangular boundary by audible frequency can measure membrane stress indirectly. In this paper, through the experimental tests it is proved that the equipment can be used for not only the membrane material of type A but also for types B and C. In addition, it is proved that the developed measurement equipment is available to stably measure the membrane stress which exists in the membrane material of the actual membrane structures.

This study measured temperatures and albedos of urban surfaces for different colors and materials during summer, and calculated the energy budget over different urban surfaces to find out the thermal performance affecting the heat built-up. The study selected six surface colors and 13 materials common in urban landscape. Their surface temperatures (Ts) and albedos were measured at a given time interval in the daytime from June to August. Average Ts over summer season for asphalt-colored brick was $4.0^{\circ}C$ higher than that for light red-colored one and $9.7^{\circ}C$ higher than that for white-colored one. The Ts for artificial surface materials of asphalt paving, brown brick wall, and green concrete wall was $6.0^{\circ}C$ higher than that for natural and semi-natural ones of grass, grassy block, and planted concrete wall. There was the greatest difference of $16.3^{\circ}C$ at midafternoon in the Ts between asphalt paving and planted concrete wall. Average albedo over summer season of surface materials ranged from 0.08 for asphalt paving to 0.67 for white concrete wall. This difference in the albedo was associated with a maximum of $15.7^{\circ}C$ difference at midafternoon in the Ts. Increasing the albedo by 0.1 (from 0.22 to 0.32) reduced the Ts by about $1.3^{\circ}C$. Average storage heat at midday by natural and semi-natural surfaces of grass and grassy block was about 10% lower than that by artificial ones of asphalt, light-red brick, and concrete. Reflected radiation, which ultimately contributes to heating the urban atmosphere, was 3.7 times greater for light-red brick and concrete surfaces than for asphalt surface. Thus, surfaces with in-between tone and color are more effective than dark- or white-colored ones, and natural or semi-natural surfaces are much greater than artificial ones in improving the urban thermal environment. This study provides new information on correlation between Ts and air temperature, relationship between albedo and Ts, and the energy budget.

Van Doesburg founded the magazine De Stijl with Mondrian in 1917. De Stijl movement was influenced by Cubist painting as well as by the mysticism and the ideas about ideal geometric forms in the neoplatonic philosophy. De Stijl proposed ultimate simplicity and abstraction by using only straight horizontal and vertical lines and rectangular forms. Furthermore, their formal vocabulary was limited to the primary colours, red, yellow, and blue, and the three primary values, black, white, and grey. The works avoided symmetry and attained aesthetic balance by the use of opposition. Vertical and horizontal lines are positioned in layers or planes that do not intersect, thereby allowing each element to exist independently and unobstructed by other elements In 1924 their different concepts about space and time were split between Van Doesburg and Mondrian. Van Doesburg launched a new concept for his art, Elementarism, which was characterized by the diagonal lines and rivaled with Mondrian's Neo-Plasticism. The works of De Stijl would influence the Bauhaus style and the international style of architecture.

Building energy saving have been put effort in a long time since buildings consume about 40.6% of total energy use, where heating, cooling and electrical lighting requirement results in energy consumption of building significantly. The window is an important part of building envelope, it usually brings a certain heat load from solar radiation while it allows light passing through, and properly leads to overheating in summer, hence the cooling load increase sand cause of thermal uncomfortable factor. The purpose of this study was to evaluate internal shade performance according to color and materials. There is growing interest in improving the sense of comfort among students who spend most of their time in the classroom. The study examined thermal environment and light environmental performance according to the color and materials of internal blinds to the school classroom. The results of this study were as follows; Among wooden blinds, aluminium blinds, and polyester blinds, the aluminium blinds were most excellent. In addition, among white blinds, light brown blinds, dark brown blinds, the light brown were most excellent.

This paper proposes a SPIT(Spam over IP Telephony) prevention framework which is using expanded white-list in real-time VoIP environment. The existing schemes are vulnerable to attack from spammers since they can continue to transfer SPIT upon changing their ID. And existing frameworks have experienced the time delay and overload as session initiates due to real-time operation. To solve these problems, the proposed scheme expands the scope of white lists by forming social networks using the white list, but it is to decide quickly whether pass a caller ID without searching the entire database. The proposed framework takes the three-stage architecture and the fast scoring system. The proposed framework minimize user's inconvenience and time delay for initiation of session, therefore, it is proper for real-time VoIP environment.

Standard carnations are widely used in flower design as a mass flower, but there is a limit to the use in that it can not be used in various colors in addition to its own color. The purpose of this study was to investigate how does artificial dyes affect vase life, using standard carnations, and to improve utilization of dyeing carnations in floral design. Using standard carnation 'White Liberty', dyeing experiment was performed according to four kinds of chemicals for each of six dyes. Six different dyes from Koch(Robert Koch industries Inc., USA) as follows light blue(2386), lime green(2315), christmas red(2506), lavender(2200), orange fire(2268) and black(2012) have been used and four different chemicals as follows distilled water, 4% ethanol, 3% sucrose and 100mg·L^-1 citric acid have been used with the cut Dianthus caryophyllus 'White Liberty'. As a result, six different dyes showed fast and excellent dyeing with 3% sucrose and 100mg·L^-1 citric acid treatment. But vase life in other dyes except black and lavender tended to be similar to control(7 days).

This study evaluated the use of endoscopy to examine jaw cysts during the operation. Fifteen jaw cysts were explored with a endoscope immediately before and after enucleation. Endoscopic findings were evaluated and recorded with video tape. Before enucleation, there were many white fibrous floating materials within the cystic cavity. Cystic lining showed smooth and regular appearance with capillary network. However, there were some fibrous scar tissues and irregular architecture in preoperative infection. After enucleation, there were white shiny bony surfaces with fresh vascular network. In some cases, floating fibrous tissues remained after removal.
