This study is about heat island as one of the urban climate variation factors in urbanized modern society, which compared and observed the thermal characteristics both the downtown location and the outskirt site in summer. The diurnal air temperature range at each point is $12.6^{\circ}C$ in the downtown location and $14.3^{\circ}C$ in the outskirt site, so, it was found that the diurnal air temperature range in the outskirt site was $1.7^{\circ}C$ higher than in the downtown location. There was 20 minutes difference to reach the highest temperature between globe temperature and air temperature in the downtown location, however, the time spent to reach the highest temperature between globe temperature and air temperature in the outskirt site was the same. When we compared the globe temperature between the downtown location and outskirt site, we found that the temperature in the outskirt site was lower than in the downtown location after sunset due to the sudden temperature drops, although the exposed time to insolation in the outskirt site is longer. The average of globe temperature difference on the sample days was $1.1^{\circ}C$, the average of surface temperature difference on the sample days was $1.0^{\circ}C$, and the average of air temperature difference on the sample days was $2.0^{\circ}C$ Thus, it was found that the average of air temperature difference was higher than the average of globe temperature and the average of surface temperature. The result of this study is that the urban environment factors have more effect on the air temperature difference than globe temperature and surface temperature.

After World War II, Japan experienced a great political and social shift, which brought a concern of emerging public landscape in urban development. This paper analyses the management of the aesthetic intentions in urban design effort. We reviewed the development of various public installation of artworks concerning urban landscape aesthetics through its administrative process in chronological order. The monuments during the first decade marked a shift in emphasis from the militarism of the pre-war and wartime period to one of peace. However, some of the monuments and sculptures are not immune to controversy. This became an issue that could no be ignored by public officials whose responsibility was to place the sculptures while maintaining sensitivity to public opinion. As public administrators began to consider the possibility that sculptures may contribute to improving public amenities, the contextual concepts were basically ignored. Some of the programs in 1970s began to show more respect to the context, while other programs in this period expressed more interest in educational aspects of sculptures in the public spaces. Urban development projects also seek to introduce artworks integrated to their urban design concepts in 1990s. Generally, the administrators responsible for these programs were rarely trained in any relative field study other than public administration. Installing sculptures tended to be considered as part of public works projects on the level of urban planning and construction. The general public is basically removed from participating in the critical decisions that actually impact their lives in relation to the artworks. In conclusion, public art in japan has unique social and historic background both in its advantages and disadvantages. Issues pertaining to art in public spaces have evolved over the decades as the term "sculpture pollution" began to appear by the mid 1990s. most of the problems originated in either the lack of monumentality, contextual consideration, quality, or public participation. From another point of view, these programs played great roll in the development of modern Japanese sculpture and patronizing process, and the creation of new urban landscape with aesthetic value. In this sense, they must be considered as successful and noteworthy examples of cultural administration and urban design policy.

Information superiority is an essential factor in modern warfare and it can be archived by efficient information exchange between systems. Various computing systems are installed on the today's navy vessels. However, it is hard to improve interoperability and efficiency of information exchange since the configurations of installed systems are varying. The military standard and commercial standard are mix-used between systems. In this paper, we propose an information exchange architecture based on Pub/Sub model as a communication middleware to improve interoperability as well as enhancing scalability. We also propose a novel tree matching algorithm to improve a performance of PubSub broker. In the proposed algorithm, each tree nodes have information about predicates of subscription that can reduce event matching time. The performance evaluation results show our proposed algorithm reduces time for matching predicates compare with other algorithms.

This study aims to comparatively analyze the characteristics of light expression shown in the exhibition spaces of architects Richard Meier and Kuma Kengo, who constructed the element of invisible light into visible forms within space, using diverse techniques and components. As for the methodology therefor, it was attempted to conduct theoretical consideration of light, to experience the spaces of light by producing diverse spaces with architectural space components, that is, space, form, material, structure, and color, and to find out what space characteristics are perceived by perceivers from the interaction of the components. As for the research scope, this study intended to identify the concepts and characteristics of light and compare light in spaces, focusing on works of Richard Meier who constructed functional and mechanical spaces based on Le Corbusier's architectural language in the West and works of Kuma Kengo who claimed regionalism architecture in the East. In particular, this study intended to comparatively analyze the methods of using materials according to the filtering of light that appears different between the two architects in case that light enters into their exhibition spaces, and the effects of light production that arise from the differences, thereby pointing out the characteristics of diverse light expressions within the spaces of modern architecture. On this, this study investigated methodological differences of the two architects, who are based on East and West thoughts, in expressing light in spaces in various forms through brightness and darkness, light transmission and shadows appearing according to the nature of light, and color and materials. It is hoped that this study will provide an opportunity for promoting better understanding about other architectural cultures as well as understanding the characteristics of light in exhibition spaces.

Synthesis process from the data produced by different types of sensor into a single information is being studied and used in a variety of platforms in terms of multi-sensor data fusion. Heterogeneous sensors has been integrated into various aircraft and modern avionic systems manage them. As the performance of sensors in aircraft is getting higher, the integration of sensor information is required from the viewpoint of avionics gradually. Information fusion is not studied widely in the view of software that provide a pilot with fused information from data produced by the sensor in the form of symbology on a display device. The purpose of information fusion is to assist pilots to make a decision in order to perform mission by providing the correct combat situation from avionics of the aircraft and to minimize their workload consequently. In the aircraft avionics equipped with different types of sensors, the software architecture that produce a comprehensive information using the sensor data through multi-sensor data fusion process to the user is shown in this paper.

Importance of color in floral design has been emphasized for long time, but it is difficult to find out standardization of color for floral design and for educational system. Wedding bouquet is major and important part of floral design and it shows same problem. The research is concentrated on color image analysis of wedding bouquet designs which have been submitted for 'Interflora World Cup Competition' with the intention to utilize the study result as the basic information of floral design. Colors of wedding bouquets from 20 different countries were analyzed. All of designers chose high brightness and saturation more for designing the bouquets. Warm colors and cold colors have been taken in similar portion. Blue color has been rarely used and it is probably because of the rarity of blue flowers. This study shows each continent has different color preference. European designers used wide variety of colors while Asian designers preferred red color. From this study, we found that color image scales of wedding bouquets represent 8 images out of 12 representative images. Four exceptions are 'clean', 'elegant', 'gentle' and 'modern' images.

The architecture reflects geographical characteristics such as geographical environments and climate, it has the characteristics and cultural characteristics of the region that has been constructed. Hansen Village constructed in Period of Japanese Occupation at 'Sorok-Island' in Go-heung, Jeollanam-do was also based on this point. The village, which is a ward of Sorok-Island Province, consists of a village in which patients are self-sufficient in economic and social activities, unlike the modern hospital systems where patients and treatments are concentrated in a single room. Additionally, the facilities for patient acceptance were gradually expanded, with limited interaction with external. Sorok-island shows the expansion of the village center where the new village is formed with the increase of the number of the early adopters in the 1910s and the accommodation facility is built, and it gradually increases the necessary space by opening and repairing the existing facilities by the 1990s Change. In addition, the spatial composition of the village can be divided into three types : decentralized, centralized and single-shift ; it has the same causal relationship as the village's formation. The purpose of this study is identifying the uniqueness of Sorok-Island by analyzing the correlation between the formation of a village to accommodate Hansen Patients in Sorok-Island and the spatial Component Factor.

In modern architecture, the concept is the central axis of the design process, but it is not yet a building. The concept is modified in the process of realization because it captures only a part of reality. However, in the works of some Japanese architects, the concept seems to have become almost a building. In this study, I tried to find the cause of such a contradictory situation centering on House N of Fujimoto Sou, which is a representative architect of such tendency. Specifically, I analyzed the concept of House N by dividing it into aspects of function and representation. The reason for this was to see if the functional aspects of the concept were not modified in the first place, or if the representational aspects of the concept covered the functional aspects. For this purpose, I used WLVAE, which is a visual analysis tool, to analyze the functions of design concepts, along with the analysis of photographs, drawings, and diagrams. As a result of the analysis, House N was also modified to conditions of reality in the process of building, but the initial purity was emphasized in the representation of the concept, so that the building seemed to be very conceptual. This fact suggests that the architect has divided the functional and representational aspects of the concept and has focused on the latter. In conclusion this can be seen as an expression of the architect's interpretation of the relationship between the house and the city through the building.

The purpose of this study is to reveal the meaning of Le Corbusier's works focused on Maison Guiette. This House was completed in 1926, 4 year later than the work of the Citrohan and also, this house is the only remaining mixed use Dwelling in Belgium. It offers a fine example of the early architectural concepts of Le Corbusier's. Despite these important facts, the meanings of the ideas of this house have not been paid attention as much as other houses constructed at the same period, such as Maison La Roche, Maison Stein de Monzie, Villa Savoye, etc. In his book, 'Oeuvre Complete 1910-1929', Le Corbusier mentioned as follows: "A special solution imposed by Belgian housing developments characterized by a dimension of 6 meters of frontage and a very great depth. The staircase serving the various floors is like the ladder of Jacob climbs Charlie Chaplin in the "Kid" and This house is an architectural experiments of his ideas. And this study aims at analysing the relationship between Maison Guiette and spaces on the basic of Le Corbusier's 'Five Points of a New Architecture' which had a great effects on architectural history and became a fundamental elements for the change into the Modern housing. By analysing the points in regard with the Features of Architectural Concept Applied in Maison Guiette, The Five Points are the background of the interpenetration of the interior and the exterior. To attain this, this research appraises each points in detail in regards with Maison Guiette. The study of Maison Guiette will be an important architectural subject to clarify the meaning of his later works and ideas.

The façade, a fundamental function as a skin that protects human life from external environment such as cold and hot weather, snow, rain, and wind, etc, has served as a media for communication between indoor space of the building and outside space. From the media for communication point of view, the approach to envelope design, in which environmental elements are transmitted internally through the filtering of external environments, has been evolving in various ways from the past to the present. Today, modern architecture technologies including curtain wall systems and user-friendly computer programming and environmental analysis programs demonstrate a differentiated approach to envelope design related to the indoor environment. For this reason, it is worth noting that the envelope design factors and trends that appear variously in the UNStudio's projects before and after the 2000s. The factors reflected in the envelop design in conjunction with the indoor environment obtained through the case study of the UNStudio's office projects were daylight environment, thermal environment, ventilation, noise, privacy and view, and consideration for daylight environment and thermal environment was reflected in many cases through the case study. Looking at the changes in the diagrams in order of year, it can be seen that the envelope design using the environmental analysis tool has been performed since 2006. This is a clue to show the envelop design changes from the conceptual method to the data-based one. The diagrams and analysis results related to the envelop design showed that the thermal environment related to solar radiation was the most, and no diagrams and analysis related to the indoor illumination were found. Since 2010, PV panel installation has been shown in the envelope design, which can be found in the increased efficiency of PV panels due to the technological advances and the decrease in production cost.
