In this study, we pursue a new direction for system modeling by introducing the concept of granular models, which produce results in the form of information granules (such as intervals, fuzzy sets, and rough sets). We present a rationale and several key motivating arguments behind the use of granular models and discuss their underlying design processes. The development of the granular model includes optimal allocation of information granularity through optimizing the criteria of coverage and specificity. The emergence and construction of granular models of type-2 and type-n (in general) is discussed. It is shown that achieving a suitable coverage-specificity tradeoff (compromise) is essential for developing granular models.

Purpose - This research mainly studied with the promotion of "one belt and one road "initiative's strategy and the construction of China, Japan and South Korea Free Trade Zone, China exports urgently needed industrial products to Japan and South Korea, which will not only help digest excess industrial capacity, optimize China's industrial structure, but also promote the economic development of Japan and South Korea. Research design, data, and Methodology - The study conducted a survey on 2018 year new revision of China-Korea Japan's data. Results -This study shows that In this process, multinational enterprises, as pioneers of economic development, play an irreplaceable role. However, due to the differences between laws of different countries and their own corporate culture concepts, enterprises in different countries will inevitably encounter various conflicts in the process of development. Conclusions -This requires our enterprises to have awareness of legal risk prevention in the process of development, and to study the corporate culture of relevant enterprises to truly achieve win-win cooperation.

This study aims at developing the interior design method of Public Toilet in office building. There needs new concepts in Public Toilet where we felt dirty smelling and dismal in the past. And the behavior in the Public Toilet become various such as combing the hair making-up changing the clothes rinsing out mouth and so on. Nowadays The Public Toilet of office building shows indirectly the hierarchy and the management philosophy of its enterprise, This study treats with the design items such as unit space zoning plan lighting plan and air-conditioning plan and construction method of Public-Toilet in office building. As a result of this study the interior design methods of Public Toilet must reflect use of fitting material lighting plan user's needs and functional divide.(Powder Zone and Physiology Zone) These result will become basic data of future interior design in Public Toilet.

Structures are designed in such a way that they behave in a nonlinear manner when subject to strong ground motions. Energy concepts have been widely used to evaluate the structural performance for the last few decades. Energy based design can be expressed as the balance of energy input and the energy dissipation capacity of the structure. New research is needed for multi degree of freedom systems (MDOFs)-real structures- within the framework of the energy based design methodology. In this paper, energy parameters are evaluated for low-, medium- and high-rise steel special concentrically braced frames (SCBFs) in terms of total energy input and hysteretic energy. Nonlinear dynamic time history analyses are carried out to assess the variation of energy terms along the height of the frames. A seismic energy demand spectrum is developed and hysteretic energy distributions within the frames are presented.

The deeping interests and research toward Entrepreneurship, which is considered as an potential alternative for solving the continuing economic recession in the $21^{st}$ century, have grown. The process and methodology of the research could not be systematically arranged and the results of the research lack in efforts on the application of increasing suceess ratio in starting new business. This study adopted corpus methodology, through which we try to analyzes the knowledge structure in entrepreneurship research, derive essential concepts and the consisting domains in venture research. Based on the results of analysis, this study constructs the knowledge structure of venture research in a form of knowledge ontology. The results of the study could be a ground for entrepreneurship research and utilized as implication for a creation of construction for the entrepreneurship knowledge ontology.

The purposes of this paper are the review and derivation of design characteristics for the new construction of the practical flexible manufacturing system. The basic ideas to analyze the manufacturing system which is the automatically operated are dependant on the various manufacturing procedures in factory. The practical flexible manufacturing systems have various mechanical subsystems appropriated fur the final manufacturing products. Therefore the systems have the various kinds of hardwares as well as softwares. We study the software for the practical flexible manufacturing system designed and developed in the Halla University with the related company. Specially the design concepts and using specifications of all subsystems which are composed of mechanical and electronic movements of the product are analyzed and introduced in this dissertation.

This paper presents an optimal decision model for minimizing the life-cycle cost of steel box girder bridges. The point is that it takes into account service life process as a whole, and the life-cycle costs include initial (design, testing, and construction) costs, maintenance costs and expected failure costs. The problem is formulated as that of minimization of expected total life-cycle cost with respect to the design variables. The optimal solution identifies those values of the decision variables that result in minimum expected total cost. The performance constraints in the form of flexural failure and shear failure are those specified in the design code. Based on extensive numerical investigations, it may be positively stated that the optimum design of steel box girder bridges based on life-cycle cost approach proposed in this study provides a lot more rational and economical design, and thus the proposed approach will propose the development of new concepts and design methodologies that may have important implications in the next generation performance-based design codes and standards.

In this paper, an optimum design model for minimizing the life-cycle cost (LCC) of high-speed railway steel bridges is proposed The point is that it takes into account service life process as a whole, and thus the life-cycle costs include initial (design, testing, and construction) costs, maintenance costs, expected strength failure costs and expected serviceability failure costs. The problem is formulated as that of minimization of expected total life-cycle cost with respect to the design variables. By processing the optimum LCC design the effective and rational basis is proposed for calculating the total LCC and the sensitivity analysis of LCC is peformed. Based on a numerical example, it may be positively stated that the optimum LCC design of high-speed railway steel bridges proposed in this study provides a lot more rational and economical design, and thus the proposed approach will expedite the development of new concepts and design methodologies that may have important implications in the next generation performance-based design codes and standards.

Through the 20th century architectural theory of rational thinking and the principles according to the statement of the firm, Le Corbusier's early works by analyzing the language of architecture, including his architectural concepts and helps the understanding of modern architecture. Masters of modern architecture as a place among the works of Le Corbusier in the 1920s, 'Le Corbusier's White Period' homes to target by age, and that his initial concept of the formation process of clarifying, further the construction of his golden age will be the key to understand. I selected housings from Maison Citrohan to villa Savoye, the category of architectural elements by considering the development process, he examines developments of the concept of modern architectural space. In analysis process, First of all, I am focused on between each element in the development process to review and explicate the integration process. The advent of the machine which he lived, because of its incredible potential reorganization of human society, as well as to celebrate the start of a new lifestyle. His architectural language of the times in the machinism could achieve progress and modern art, which is a new interpretation of the natural world.
