As the 21st century signifies an information-oriented society, the computer integration takes place in all walks of human presence. Needs for computer and network-integrated automation present new challenges in military as well as commercial facility systems engineering. Since the first intelligent building appeared in USA in 1984, it gradually became an essential capability for the building industry requirement these days. Intelligent Building System(IBS) is evolving to be very complex because there are many subsystems such as telecommunication(TC), office automation(OA), building automation(BA), security, construction environments, etc. During the planing phase of IBS development, therefore, a disciplined systems engineering must be performed to analyze stake- holder's requirements to build an optimized system while minimizing trial-and-error expenses and risks. This paper presents a conceptual design of BAS applying systems engineering methods. The contribution of this study includes the development of IBS subsystem specification for building automation subsystem, which is a part of IBS, using the methodology of requirement analysis, functional analysis, synthesis, and verification. A computer-aided systems engineering s/w, RDD-100, was used to improve the system design efficiency and to promote the product design knowledge management for reuse in later design programs.

This report introduces the structural design of Hibiya Mitsui Tower built in Tokyo Midtown Hibiya. The upper part of this tower is used for offices and the lower portion is for commercial facilities and a cinema complex which need the large open spaces. The 192m-high building has 35 floors above ground and 4 below ground. The structure is a steel frame using CFT columns to feature the high-performance oil dampers and the buckling restrained braces for vibration control. First, an outline of the structural design of this building is presented. Second, we introduce the transfer frame adopted to realize the large open spaces in the lower part, and the long column supporting the corner part of the high-rise building to avoid making a shade on the adjacent Hibiya Park, which are the feature of this building. Finally, we present an outline of the latest highly efficient semi-active oil dampers adopted in this building, and the vibration responses of this tower.

CFD is applied to evaluate pedestrian wind comfort at outdoor platforms in a high-rise apartment building. Model validation is focused on generic building sub-configurations that are obtained by decomposition of the actual complex building geometry. The comfort study is performed during the design stage, which allows structural design changes to be made for wind comfort improvement. Preliminary simulations are performed to determine the effect of different design modifications. A full wind comfort assessment study is conducted for the final design. Structural remedial measures for this building, aimed at reducing pressure short-circuiting, appear to be successful in bringing the discomfort probability estimates down to acceptable levels. Finally, the importance of one of the main sources of uncertainty in this type of wind comfort studies is illustrated. It is shown that the uncertainty about the terrain roughness classification can strongly influence the outcome of wind comfort studies and can lead to wrong decisions. This problem is present to the same extent in both wind tunnel and CFD wind comfort studies when applying the same particular procedure for terrain relation contributions as used in this paper.

Quickly picking up some valuable information from massive manufacturing event stream usually faces with the problem of long detection time, high memory consumption and low detection efficiency due to its stream characteristics of large volume, high velocity, many variety and small value. Aiming to solve the problem above for the current complex event processing methods because of not sharing detection during the detecting process for massive manufacturing event streams, an efficient complex event processing method based on multipattern sharing is presented in this paper. The achievement of this paper lies that a multipattern sharing technology is successfully used to realize the quick detection of complex event for massive manufacturing event streams. Specially, in our scheme, we firstly use pattern sharing technology to merge all the same prefix, suffix, or subpattern that existed in single pattern complex event detection models into a multiple pattern complex event detection model, then we use the new detection model to realize the quick detection for complex events from massive manufacturing event streams, as a result, our scheme can effectively solve the problems above by reducing lots of redundant building, storing, searching and calculating operations with pattern sharing technology. At the end of this paper, we use some simulation experiments to prove that our proposed multiple pattern processing scheme outperforms some general processing methods in current as a whole.

지속가능한 국토개발과 지역균형발전을 위하여 세종시(행정중심복합도시), 기업도시(기업중심), 혁신도시(혁신클러스터) 등 다양한 형태의 신도시가 개발되고 있다. 특히, 세종시가 원안대로 추진되게 됨으로써, 혁신도시의 건설은 보다 탄력을 받게 될 전망이다. 기존 수도권의 신도시와는 달리 혁신도시는 공공기관 및 연구기관을 중심으로 혁신클러스터가 조성되고, 주로 지방의 중소도시 및 농촌지역에 신도시가 형성된 다는 측면에서 도시개발의 차이가 있다. 또한 인구는 대부분 2만 내외의 중소규모 신도시 및 신시가지로 개발되고 있다. 그러므로 혁신도시 내의 교육시설 및 문화시설은 도시규모 및 도시기능상 독립적인 수요를 확보하기에는 한계가 있다. 따라서 다양한 시설을 복합화하여 문화수요를 확대하는 것이 바람직하고 기존 모도시와의 공동이용을 도모하는 것이 도시관리의 차원에서 효율적이라고 할 수 있다. 본 논문에서 는 다른 혁신도시와는 달리 2개 광역지자체의 공동혁신도시이자 혁신도시 중에서 가장 규모가 큰 신도시형으로 조성되는 나주혁신도시를 사례로, 혁신도시 문화교육시설을 활용한 기능과 공간의 융복합적 복합 문화벨트의 조성을 기존의 분산적 문화시설계획방식에 대한 새로운 대안으로 제시하였다.

Characteristics of color application indicated from Kirchsteigfeld is presented the various points of view to be preserved urban housing color. It had been handled as environmental color by view point of community and connectivity rather than color scheme of single housing. First, color to be consisted of basis for urban entirely as background color in urban housing complex has been indicated the bright and cheerful feelings and expressed to be introduced mostly from the single color system. Second, characteristics to be inhibited strongly from housing complex had been indicated by restricted four types of color, formulated the overall context and change through accent and the change from disposition of principal and the accessary of color scheme. In this case, it was not regular formulation, but as a whole category view, it could be provided by orderly regularity system strictly Particularly it had been applied as a whole for lightness change by single color, introduced the different color of building to be centered or remained by a visual point. This had been formed to introduction of color by stand points of housing group not introduction to color by sole concept of building. Third, emphasizing of morphologic feeling by using of difference of lightness, it could be indicated the mild and comfortable stereo-type sensibility from the overall types of housing, we could understand for formation of color code by lightness of slightly differences. Fourth, it had been taken the convenient adaptation method for maintenance of simple graphic system as a environmental color. It has considerable advantage for sustainability of color to indicate on finishing material, form and detail in architecture, as the sole separated color not to be complicated when to be painted over and again or managed continuously.

Livestock odor is comprised of mixed type of odorous compounds. Among these, ammonia ($NH_3$) and hydrogen sulfide ($H_2S$) are the two known major odor causing substances. Because high odor concentration reduces productivity of livestock and causes damage to the surrounding communities, quantitative analysis is needed to manage the odor inside and outside the livestock facilities. It is also necessary to evaluate odor dispersion according to the distance between the receptors taking into account the influence of odor source and weather condition. Therefore, in this study, we tried to evaluate the internal environment and odor dispersion from experimental pig house considering weather conditions. An experimental farm was specifically selected to eliminate the interference of odors generated by adjacent farms. $NH_3$ and complex odor were quantitatively analyzed using a gas detector and air dilution sensory method. The concentration of $NH_3$ and complex odor in pig house showed a distinct concentration difference according to the cleaning and ventilation conditions. $NH_3$ concentration and complex odor was lower than emission standard in the pig house and at the site boundary. The average $NH_3$ concentration (P1~P3) and the $NH_3$ concentration at the site boundary (S1) were strongly correlated with R=0.77. While the correlation for complex odor inside and at the site boundary had R=0.52. The correlation coefficient between $NH_3$ and the complex odor was 0.80.
