In order to develope a common ground system, a general procedure language that can be used in both EGSE and MCS is primarily needed. As the first step in developing a common test and integration procedure language, KARI's ATS for AIT and MCE for GS were compared to some of the most representative languages such as PLUTO regarded European standard, STOL and ELISA and PIL. Based on the analysis, design features of developing a common test and integration procedure language were presented.

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.

The purpose of this study is to examine the preferences about component elements of Public Space of apartment housing in Daegu. This study is based on the survey of thirty nine apartment complex in seventeen construction companies to create images and component elements types. Also, by using an questionnaire analysis derived from a precedent study, component elements in the porch and interior common space of apartment residents are comprehended. The survey analysis of the porch is researched and divided according to a form of porch, designs and lights of ceiling. Interior common space is analyzed by several elements; forms of core, designs and lights of ceiling, design of walls and floors, necessity of windows, and necessity of public facilities. The questionnaire is composed of 40 items and it was returned by one hundred sixty two respondents. As a result of the study, After the enforcement of price deregulation, the porch and interior common space of apartments has had improved quality. However, by questionnaire survey of respondents showed preferences of each element and necessary facilities. Thus, i hope that this study is an excellent source for apartment design.

This paper presents a design method for combinational digital logic systems using time domain based multiplexing and common multi-terminal extension decision diagrams. The proposed method can reduce the 1)hardware, 2)logic levels and 3)pins. In the logic system design, we use two types of decision diagrams(DDs), that is the common binary decision diagrams and CMTEDDs. Also, we propose an algorithms to derive common multiple-terminal binary decision diagrams from CBDDs, and CMTEDDs from CMTBDDs. The CMTEDDs over CBDDs is more compactness in terms of number of non-terminal nodes, where the nodes for output selection variables are not included in the non-terminal nodes. In the logic design, each non-terminal nodes of an CBDDs and an CMTEDDs is realized by a multiplexer(MUX). In addition, we compare the proposed TDBM realization with the conventional one.

This paper presents a design method for multiple-output combinational digital logic systems using time domain based on multiplexing(TDBM) and common multi-terminal extension decision diagrams(CMTEDD). The CMIEDDs represents extension valued multiple-output functions, while TDBM systems transmit several signals on a single lines. The proposed method can reduce the 1)hardware, 2)logic levels and 3)pins. In the logic system design, we use two types of decision diagrams(DDs), that is the common binary decision diagrams(CBDDs) and CMTEDDs. Also, we propose an algorithms to derive common multiple-terminal binary decision diagrams(CMTBDD) from CBDDs, and CMTEDDs from CMTBDDs.

Recently, global warming has become severe, and regulation is established for carbon savings each field. its regulation is applied to various fields using IC engine such as automobile, ship, agricultural machine. Therefore engine block applied Common Rail Direct Injection(CRDI) technology, that carry out thermal-structure analysis to examine design. The thermal load about 900℃ by explosion was applied in cylinder. And pressure about 9 MPa(90 Bar) was applied to structure analysis. As a result, it was the highest at 185.99℃ at the top of cylinder. Static-structure analysis applied thermal load, that was shown maximum equivalent stress at 142.59 Mpa and Maximum principal stress 145.03 MPa, Minimum principal stress -149 MPa. When compare analysis results to material property, it design is safety structurally.

To analyze recent changes in designer-specific garment composition, detail, and design elements of jackets, we classified jackets from the Paris Haute Couture Collection from 2000 S/S to 2019 F/W according to their designers and examined their characteristics. Our analysis of the jackets by Armani, Chanel, Dior, Jean-Paul Gaultier, and Valentino shows that the hour-glass silhouette was most common in Armani, Chanel, Dior, Jean-Paul Gaultier and Valentino jackets; Chanel used more straight silhouettes compared to other designers. Most jackets, regardless of the designer, had midlength waist-to-bottom, tight sleeves fitted to the body, natural shoulder shape, and solid color. Moreover, woven fabric was the most common material. Jackets with no collar were the most common for Armani, tailored collars for Dior and Jean-Paul Gaultier, and standing collars for Chanel and Valentino. For the closure method, Armani used hook-and-eye, Chanel, Jean-Paul Gaultier, Valentino used button closures, and Dior used snap closures the most. New design attempts by designers are bringing details and design elements together. In an era characterized by an abundance of designs and frequent replacement of each brand's creative designers, it is important to create and maintain a brand's unique design identity and philosophy that can meet consumers' elevated standards, which tend to be biased towards new and stimulating designs due to the development of the IT industry.

In this paper, we propose a new method for power estimation in nodes of multi-level combinational circuits and describe its application to the extraction of common expressions for low power design. It is assumed that each node is implemented as a complex gate and the capacitance and the switching activity of the nodes are considered in the power estimation. Extracting common expressions which is accomplished mostly by the extraction of kernels, can be transformed to the problem of rectangle covering. We describe how the newly proposed estimation method can be applied to the rectangle covering problem and show the experimental results with comparisons to the results of SIS-1.2.
