When it comes to the architecture design, Kuma Kengo rejects a strong and violent subject-centered position and advocates the design that is object-oriented. As can be seen in 'gentle architecture', 'three lows principle', 'natural architecture', and 'connecting architecture', he clearly expresses the objective nature of architecture design in those terms. In this respect, the purpose of this study is to make a close inquiry into the meaning, effect and characteristics of objectivity. In particular, we try to identify the contents of 'impure architecture', which has a clear ambivalence to be an instrumental expression strongly settled in the objectivity, in an aesthetic standpoint. To do that, we systemized the concept of mimesis and the theory of subversive appropriation by Walter Benjamin and Theodor Adorno in to a frame of interpretation. By systemizing translation, subversion, verbalization and the dialectic structure of the aesthetics of negation, we interpreted the features of his works as an objective work and 'impure architecture'. His objectivity leads the situation by subversively appropriating the inherent elements of architectural conditions based on a dialectic solution in which inquiries on logical and scientific materials have played a critical role. Above all, through all these processes, he tried to suggest a language as a new technique for materials and structures. Ultimately, we could find out that this object oriented design sublates a subject oriented way that is monolithic and repetitive regardless of objects. Rather, it is a way that is effective in creating a new way of design by making a different approach to a new object rather unfamiliarly, yet deeply.

최근 부각되고 있는 텔레매틱스와 위치기반서비스의 효율적인 구축을 위해서는 실시간으로 수집되는 방대한 분량의 위치 데이터의 저장, 질의, 프리젠테이션 동을 포함하는 이동체 기술이 필요하다. 특히 물류분야에서 이동중인 차량의 데이터에 대한 효과적인 검색과 분석을 위해서는 응용별 특화된 형태의 데이터를 획득할 수 있는 질의구문이 요구되며, 전통적인 데이터베이스 질의어와 비교할 때 그 구조는 복잡한 양상을 보인다. 이에 대한 효과적인 대안으로는 SQL과 같은 표준화 데이터베이스 언어를 통한 접근을 고려할 수 있다. 따라서 이 논문에서는 e-로지스틱스 기반의 차량관제에서 요구하는 질의에 대하여 SQL를 확장한 이동체 질의어 (MOOU)를 제안하고, 이를 효과적으로 처리하기 위한 질의처리기를 설계 및 구현한다.

기업에서는 급속한 컴퓨터 환경 변화 및 사용자 요구 증가 등의 요구들에 대응하기 위하여 많은 시간과 비용을 들여 기 개발되어 운영중인 시스템을 유지보수 한다. 하지만 대부분 임시적인 이러한 작업들은 많은 코드의 중복과 최적화 되지 않은 시스템 구조를 산출하여 결국에는 전체적인 성능 저하를 가져오는 등의 문제를 발생시키게 된다. 또한 초기 개발 후 다른 개발자에 의해 작성된 코드는 개발관련 문서의 분실 및 부족, 기존 시스템 개발자의 부재 등의 문제로 코드의 이해와 재사용의 어려움 등의 한계점을 갖게 되었다. 이번 연구는 이러한 코드 재사용의 한계를 극복하기 위하여 객체단위를 재사용 할 수 잇는 객체지향 기반의 Refactoring 프로세스를 제시하고, 이를 D사에서 개발한 윈도우 시스템 개발 도구인 D2D에 적용한다. 또한 이의 과정에서 얻어진 시스템 성능 향상과 개발 및 유지보수 비용의 감소, 구조와 클래스들의 최적화 등의 실제적인 효과 증대 사례를 보인다.

The purpose of this study is to analyze the organic forms, expressions, and characteristics of Alexander McQueen's fashion design and to present various materials for understanding and utilizing this organic design style. The criteria for organic design expressions and characteristics were classified through a literature review, and the organic design characteristics of Alexander McQueen's fashion were then analyzed. The results are as follows: First, the morphological characteristics of nature's forms are used as objects in Alexander McQueen's fashions to represent organic characteristics. Second, abstraction through the application of organic forms means creating an abstract representation of the object being represented. Abstracting organic forms occurs by partially modifying the structural features of the human body to show characteristics or by visualizing these characteristics within the surface of the natural object. Third, continuity through the expression of the formation process of organisms is characteristic of the expression of the gradual growth of organisms; this reinterpretation is based on the concept that the internal elements of natural objects affect their external forms. Fourth, the structure of using natural materials, as well as regional and cultural characteristics, is shown in the designs through use of the physical characteristics of expressions and materials that use natural elements. Fifth, symbolism through subjective thinking implies that the element of nature that an object expresses is the element that appears in nature; this includes created organisms along with environmental factors. These characteristics are best demonstrated in fashion designs that express themselves through creativity.

At present, naked-eye 3D appears more and more commonly on the facades of urban buildings. It brings an incredible visual experience to the audience by simulating the natural 3D 3D space effect. At the same time, it also creates enormous commercial value for city publicity and commercial advertisements. There is much research on naked-eye 3D visual effects, but for right-angle LED screens. Right-angle LED screen's brand-new expression method that has only become popular in recent years, how to convey a realistic naked-eye 3D effect through two LED screens combined at right angles has become a problem worth exploring. To explore the whole design ideas and production process of the naked-eye 3D impact of the right-angle LED screen, this paper is a preliminary study aimed at understanding the performance principle and expression features. Before the case analysis, first, understand the standard virtual 3D space construction techniques. Combining it with the optical illusion phenomenon, according to the expression principle of the naked-eye 3D effect of the right-angle LED screen, it can be summarized into seven expressions: Shadow, Color contrast, Background structure line, Magnify object, Object out of bounds, Object floating, Fusion of picture and background. By analyzing the optical illusion phenomenon used in the case, we summarized the main performance characteristics of the naked eye 3D effect. The emergence of right-angle LED screens breaks the limitation of a single plane of optical illusion art, perfectly combines building facades with naked-eye 3D visual effects, and provides designers with a brand-new creative platform. Understanding its production principles and main expressive features can help designers enter this innovative platform better.

As the cloud-based ICT(Information & Communication Technology) infrastructure matures, the existing monolithic software development method is evolving into a micro-service structure based on cloud native computing. To develop and operate the services efficiently under the cloud native environment, DevOps-based application development plans through MSA(Micro Service Architecture) design based are essential. A cloud native environment is an approach to developing and running applications that take advantage of cloud computing models such as automation of source distribution, container-based virtualization, application scalability, resource efficiency, and flexible maintenance through object independence. To implement this approach, the utilization of key elements such as DevOps, continuous delivery, micro service, and containers is essential, but there are not enough previous studies on case analyses or application methods of these key elements. Therefore, in this paper, we analyze the cases of application development in cloud native environment and propose the optimized application development process and development method through small and medium-sized SI projects.

A Web-based pile load test (WBPLT) system was developed and implemented in this study. Object-oriented and concept-based software design techniques were adopted to integrate the pile load test database into the system. A total of 673 case histories of pile load test were included in the database. The data consisted of drilled shaft and driven precast concrete pile axial load tests in drained, undrained, and gravel loading conditions as well as pre-analyzed data and back-calculated design parameters. Unified modeling language, a standard software design tool, was utilized to design the WBPLT system architecture with five major concept-based components. These components provide the static structure and dynamic behavior of system message flows in a visualized manner. The open-source Apache Web server is the building block of the WBPLT system, and PHP Web programming language implements the operation of the WBPLT components, particularly the automatic translation of user query into structured query language. A simple search and inexpensive query can be implemented through the Internet browser. The pile load test database is helpful, and data can be easily retrieved and utilized worldwide for research and advanced applications.

Mobile-based software development methodology has been vigorously researched from using object-oriented development methodology and component-based development methodology previous structural developing methodology. There are two types of OS in mobile platform which are android and iOS. There is a problem that the application to be developed is developed depending on the device type. To resolve this problem, first, the system structure and design method should be managed effectively. Second, a basic design guide that can be commonly adapted to the each project is required. In this paper, we define a mobile cross platform meta model based on MDA-development methodology, focusing on reusability, portability and interoperability about non - dependent part of the mobile platform. If the proposed meta-model is applied to manage the related information and all the types of Mobile-Apps become available through independent mobile app development process, henceforward, it will be much of help establishing formulaic mobile-app developmental methodology.
