It has applied the design method of face to face dimension, an MC (Modular Coordination) design method, at design steps of an apartment house for standardization of architecture. But It has been still using center line size. A construction limit isn't specific on these center line size, and dead space occurs with excessive gaps as size matching isn't performed well between structural sieve and parts. And above all, measurement before construction isn't to expect standardization, and to increase custom-made furniture. We investigate manufacture of a preferential domestic system kitchen and construction state, and we derive from a problem in viewpoints of standardization for this. And we utilized a reference plane, and we present construction document and design plan in order to solve these problems. And we analyze an effect got by application of the assembly basis aspect that we presented, and we can raise efficiency of standardization of housing and construction industry, and we light ultimately up.

Due to the nature of cavitation numerical analyses, computational optimization of a pump with respect to the cavitation properties is extremely demanding. In this paper it is shown how a combination of Transient Blade Row (TBR) method and some simplifications can be used for making the optimization process more efficient and thus possible on current generation of hardware. The aim of the paper is not the theory of hydraulic design. Instead, the practical aspects of numerical optimization are shown. This is done on an example of a radial pump and a combination of ANSYS CFX, ANSYS software tools and custom scripts is used. First, a comparison of TBR and fully-transient simulation is made. Based on the results, the TBR method is chosen and a parametric model assembled. Design of Experiment (DOE) table is computed and the results are used for sensitivity analysis. As the last step, the final design is created and computed as fully-transient. In conclusion, the results are discussed.

Background: After the resection at the mandibular site involving oral cancer, free vascularized fibular graft, a type of vascularized autograft, is often used for the mandibular reconstruction. Titanium mesh (T-mesh) and particulate cancellous bone and marrow (PCBM), however, a type of non-vascularized autograft, can also be used for the reconstruction. With the T-mesh applied even in the chin and angle areas, an aesthetic contour with adequate strength and stable fixation can be achieved, and the pores of the mesh will allow the rapid revascularization of the bone graft site. Especially, this technique does not require microvascular training; as such, the surgery time can be shortened. This advantage allows older patients to undergo the reconstructive surgery. Case presentation: Reported in this article are two cases of mandibular reconstruction using the ready-made type and custom-made type T-mesh, respectively, after mandibular resection. We had operated double blind peer-review process. A 79-year-old female patient visited the authors' clinic with gingival swelling and pain on the left mandibular region. After wide excision and segmental mandibulectomy, a pectoralis major myocutaneous flap was used to cover the intraoral defect. Fourteen months postoperatively, reconstruction using a ready-made type T-mesh (Striker-Leibinger, Freibrug, Germany) and iliac PCBM was done to repair the mandible left body defect. Another 62-year-old female patient visited the authors' clinic with pain on the right mandibular region. After wide excision and segmental mandibulectomy on the mandibular squamous cell carcinoma (SCC), reconstruction was done with a reconstruction plate and a right fibula free flap. Sixteen months postoperatively, reconstruction using a custom-made type T-mesh and iliac PCBM was done to repair the mandibular defect after the failure of the fibula free flap. The CAD-CAM T-mesh was made prior to the operation. Conclusions: In both cases, sufficient new-bone formation was observed in terms of volume and strength. In the CAD-CAM custom-made type T-mesh case, especially, it was much easier to fix screws onto the adjacent mandible, and after the removal of the mesh, the appearance of both patients improved, and the neo-mandibular body showed adequate bony volume for implant or prosthetic restoration.

This paper presents a cost-effective 3D foot scanner system that provides the 3-dimensional point cloud foot data to design the custom footwear. To measure the 3-dimensional point cloud data of the foot, a CCD camera, a Non-Gaussian laser line projector and optical triangulation method are employed. Furthermore, the integrated system employs a measurement base, a frame grabber, a CCD moving cart, a stepping motor and a computer. The measurement result is saved as 3D dxf format and it could be converted to 2D essential data fer a shoe design. The experimental results demonstrate that the proposed system have the decent resolution of 1mm which is enough for last and shoe design.

Although it has been suggested that lighting influences our moods, little is known about dimensionality of mood patterns. The knowledge of consumer's mood pattern in lighting condition may provide interior designers with a valuable information for the lighting design. This article investigates the underlying structure of moods occuring in lighting conditions. Meanwhile, this examines custom-ers' desired mood type of lighting, and explores the influ-ence of individual characteristics on selecting the preffered lighting moods. The result uncovers five discriminable patterns of mood-dynamic, intimate, delightful, elegant, and serene feeling results from well organized lighting system. Among the five moods, serene atmosphere appears to be the most preffered mood from respondants. It is also found that the perceived preference of lighting atmo-sphere varies across personal characteristics of the cus-tomers, socio-economic differences and the visiting pur-poses to the coffeeshop. These findings present interest-ing and potentially valuable implications for interior de-signers that proper planning of lights which inducemoods can achieve dramatic effects and aid in the cre-ation of the desired atmosphere.

Prairie style houses in first stages of Frank Lloyd Wright's architecture activity pay a leading role in the process of house modernization as reflecting social and economic circumstances of the time based on traditional house style of the States. Wright's first work after retiring from L. Sullivan's office, Winslow house in 1983 is pioneering work predicting prairie house. This is because this house has only one modern architecture language of Wright and follow no style prevailing of the time. So, a researcher analyse Winslow house within the framework of functional thinking and new formative value creation in the modernization process of western house. Through this, The goal of this study is to find out modern characteristics and the meaning of Winslow house in modernization process prior to the 1900s. Firstly, the followings are modern characteristics of Winslow house. First, Winslow house has original planning breaking from custom based on modern functional and reasonable thoughts, and has practical space reflecting resident's inner demand. Second, Winslow house has modern new plastic value through original exterior breaking from custom and integrated shape of inner-outer space and structure. Secondly, the followings are the meaning of Winslow house in modernization process prior to the 1900s. First, Wright intend to suggest directions of residence modernization through Winslow house before designing Prairie style houses in earnest. Second, mixing of modern vocabulary and eclecticism show a sign of residence modernization process on the time. Third, inner-outer flowing space, opening space concept of Winslow house has innovative meanings predicting spacial characteristics of modern architecture.

In this paper, we describe a design of a 128bit MRAM based on a new switching architecture which is Local Field Switching(LFS). LFS uses a local magnetic field generated by the current flowing through an MTJ. This mode reduces the writing current since small current can induce large magnetic field because of close distance between MTJ and the current. It also improves the cell selectivity over using conventional MTJ architecture because it doesn't need a digit line for writing. The MRAM has 1-Transistor 1-Magnetic Tunnel Junction (IT-1MTJ) memory cell structure and uses a bidirectional write driver, a mid-point reference cell block and a current mode sense amplifier. CMOS emulation cell is adopted as an LFS-MTJ cell to verify the operation of the circuit without the MTJ process. The memory circuit is fabricated using a $0.18{\mu}m$ CMOS technology with six layers o) metal and tested on custom board.
