Software design patterns are reusable solutions to recurring problems that occur during software development. As programmers gain experience, they recognize the similarity of new problems to problems they have solved before. With even more experience, they recognize that solutions for similar problems follow recurring patterns. In this paper, as one of these reusable design-patterns, the Intermediator pattern for the efficient communication between business component is designed and implemented. Existent business components were way that follow Facade pattern. But Facade pattern is almost like the existing Interface pattern in that the communication of all the object outside the set is done by only one representative object, and this causes the traffic system to be overloaded. Therefore, the Intermediator pattern supplements the traffic overloads by improving the inefficient system of business components' communication through multi-interface, and make all communication behavior between objects done by Intermediator object which controls all actual behavior by way of Intermediator method implementation. Consequently, the Intermediator pattern is designed and implemented in this paper can bring down the level of coupling and raise the cohesion among objects, and refer to many of other object flexibly through several interfaces.

Landscape zones have been designated as aesthetic old town districts across a wide range of Nakakyo-Ku and Shimokyo-Ku, city center of Kyoto, Japan. In these districts in which traditional structures and new buildings coexist, regulations of restriction on acts such as new building's heights, shapes, materials, and colors are carried out according to local governmental landscape ordinance based on Scenic Conservation Act. And yet, minimal fulfillment of the regulations according to different designer's subjective interpretation and principle of economy is rather creating abnormal shapes not harmonized with the traditional landscape. Thus, this study aims to extract combinations between form elements of middle and high rise apartment facade that affects 'harmony' and 'mismatch' in the districts by clarifying the social rules commonly implied based on intuitive judgments (sensibility evaluation) in which human experiential knowledge is involved. As research methods, the study first analyzes the form elements of the facade through a field survey, sets up a standard model through tasks of classification and segmentation and draws computer graphic images with 99 different patterns based on it. Based on these images, this study carries out sensibility evaluation and analyzes experimental data applying the rough set theory. As a result of the analysis, the combinations of form elements that affect harmony or mismatch act greatly when the colors and shapes of the pillars, positions and the patterns of the use of the first floor are combined.

The purpose of this study was to investigate expression characteristics of korean traditionality in restaurants & Ccfes which adapted thatched roof & shingle-roofed house. As a method of this study, a case study was made to investigate for exterior and interior elements(roof type, facade, floor, wall, ceiling, door & window) of 12 restaurants & cafes in Seoul and Kyunggi Province from June 10, 2013 to December 1, 2013. The results of this study were as follows: First, traditional transformation was mostly used among the traditional expression methods. But, there was not many traditional reinterpretation method. Second, looking at each component, traditional reproduction method mostly used for roof, column and ceiling to emphasize facade. Traditional transformation method can be divided into 3 ways in detail. The first method is mixing materials of modern and traditional, and the second one is transforming traditional material and combining this with modern one. The third is removing traditional material completely and transforming totally into modern materials. Third, traditional high quality noble houses are found in luxurious Korean restaurants and luxurious cafes while common houses are found in local food restaurant and cafes. It is because traditional common houses are still considered as low quality of design and it may prevent common houses from becoming high quality of design.

Precast concrete manufacturing has proved economies of scale through the repetitive production by means of standardization, automation, and prefabrication. Advanced digital design and fabrication technologies can empower its benefits by enabling mass customization in the building design and construction. This study analyzed five case studies in terms of 1) design intent and background, 2) module development and facade construction, 3) integrated process among project stakeholder. This article has attempted to establish the following three points in conclusion: 1) Form generating digital design tools such as Rhino, CATIA, Generative Component, and Digital Project were implemented to produce parametric surface pattern and rationalization to maximize existing precast manufacturing benefits. Also, BIM program has been used to promote coordination and communication among engineering consultants and contractors, 2) In addition to traditional precast concrete materials, GFRC, RFP, brick cladding precast and 3D printed mould have been introduced to reduce the weight and cost and to comply the code from the zoning, seismic, and fireproof requirements, 3) Design-assist contract, design-assist financial support, and co-location measures have been introduced to facilitate collaboration between architect, fabricator, and contractor from the beginning of the project.

Purpose: Heat transfer analysis of recently developed 'slim type double-skin system window' were presented. This window system is designed for curtain wall type façade that main energy loss factor of recent elegant buildings. And the double skin system is the dual window system integrated with inner shading component, enclosed gap space made by two windows when both windows were closed and shading component effectively reflect and terminate solar radiation from outdoor. Usually double-skin system requires much more space than normal window systems but this development has limited by 270mm, facilitated for curtain wall façade buildings. In this study, we estimated thermophysical phenomena of our double-skin curtain wall system window with solar load conditions at the summer season. Method: A fully 3-Dimentional analysis adopted for flow and convective and radiative heat transfer. The commercial CFD package were used to model the surface to surface radiation for opaque solid region of windows' frame, transparent glass, fluid region at inside of double-skin and indoor/outdoor environments. Result: Steep angle of solar incident occur at solar summer conditions. And this steep solar ray cause direct heat absorption from outside of frame surface rather than transmitted through the glass. Moreover, reflection effect of shading unit inside at the double-skin window system was nearly disappeared because of solar incident angle. With this circumstances, double-skin window system effectively cuts the heat transfer from outdoor to indoor due to separation of air space between outdoor and indoor with inner space of double-skin window system.

As a series of 'Performance Assessment of Building Envelopes I: Double Skin Facade', three types (interior, exterior, mixed (int.&ext.)) of lightshelves and RetroLux were examined in terms of $CO_2$ emissions. It is shown that the exterior lightshelf could achieve the most energy savings (9.6-38.7%) in general office buildings due to blocking solar radiation before entering the indoor space. However, the interior lightshelf is the worst (1.4-5.2%) among three of them. The RetroLux has two components: (1) sun-reflector (first louver component), (2) light shelf for improving daylight induction (second louver component). Due to these two components, solar radiation from windows is filtered depending on seasonal variation (solar altitude). Therefore, the RetroLux can reduce 18.0-27.9% of annual energy consumption (both cooling and heating), and $552-3,290Won/m^2{\cdot}yr$ of operation cost is saved.

The purpose of this study is to analyze the correlation between fashion brand image and store space image. To investigate this study further, one of the luxury fashion brands was selected for a case study and surveys were conducted to 200 participants. This study evaluates the factors of fashion brand images that customers associate with a brand before stepping inside the flagship store. Also it analyzes the factors of store space image after the experience of the flagship store. As a result of the correlation analysis based on quantitative statistic measures, the fashion brand image and store space image coincided highest with extraordinary, young and strong characteristics. According to the space elements of the flagship store, the relationship of the brand image with the store image was investigated. As a result of analysis, customers felt the high correlation with the facade among the architectural elements of flagship store. This resulted in that customers consider that the black box of the facade represents originality of this fashion brand as a concept of spatial elements. As a practical implication, companies should understand that the architectural design is a very crucial component in designing the flagship store, as it gives customers their first impression about a brand. The brand image is required to be integrated through the exterior design of the store. The final conclusion of this study shows that the flagship store provides a space where you can experience the corporate value and brand through the space of brand experience and share an emotional image created by the brand as well.
