The change in radically changing era requires various interpretation of interior space and application according to it Minimalism shows simple and pure geometric structure and has been influencing to every aspect encompassing space till present. The features of minimalism in space is geometric structure and composition of simple and repetitive line, restrained simple space, pure and structural simplicity. When minimalism construction is discussed, the vocabulary of simplicity has been followed incidentally and has been discussed as concept of simplicity in new viewpoint through historical flow. The purpose of this study is analyzing basic features of John Pawson's ways of working and trying to define the semantics of the new simplicity concept in modern interior space. The new simplicity in John Pawson shows interactive relationship of eastern and western through basic consideration of fundamental elements such as space, light and materials. The relational simple in intermediation of the new simplicity expressed by amalgamation of eastern and western further from disparate interpretation for simplicity expressed in eastern and western is to review back the basic meaning of simplicity in minimalism. And I hope this study can offer various directions for new interior space accepting theory of the new simplicity and I think that new constructional alternative is required as physical space which can be matched with era of social, environmental chaos caused by this theory of the new simplicity.

In this paper, we introduce a new evolutionary multiobjective optimization algorithm based on the non-domination direction information, which can be an alternative among several multiobjective evolutionary algorithms. The new evolutionary multiobjective optimization algorithm proposed in this paper will not use the conventional recombination or mutation operators but use the non-domination directions, which are extracted from the non-domination relation among the population. And the problems of the modified sharing algorithms are pointed out and a new sharing algorithm sill be proposed to overcome those problems.

Design policy in Korea has been dealt as one of the industrial policies in economic policies, and it can be classified as government driven. A problem derived from this is that previous design policies have only pursued creating material values, and have overlooked the emotional values of design, such as creating cultural identity of Korea and cultural independence through it. Therefore, a new mindset of 'Cultural Era of Design' and a new role of 'Designers as Producers of Culture' must be in the strategy and system for supporting the design in Korea. This study can be divided into three major parts. First part compares and examines current design policies of Korea to seek more suitable design policies. Second part suggests a new direction for design policy by analyzing the ideas and cases of such policies. Third part surveys designers and people in related fields to collect opinions about design policies in Korea to propose directions for new design policies and ways to evaluate them. The object of this process is to find out how they, in the center of design and cultural industries, see and follow the policies. It will aid the narrowing of perceptual gap between them and the developers of policies.

The paper describes a new mean specific cutting pressure model in order to improve the accuracy of prediction of cutting force for face milling. The new mean specific cutting pressure model produces a mean specific cutting pressure and coefficients applied to existing cutting model not by traditional method but by considering intermittence and variation of chip width according to insert cutting position to take into cutter geometry machining condition and width of workpiece, and considering a mean measure force according to spindle eccentricity and mean measure force according to spindle eccentricity and insert initial position errors.. The simulated forces in X, Y, Z directions resulted from the simulated cutting model and the new cutting model are compared with measured forces in the time end frequency domains. The simulated forces in the time and frequency domains. The simulated forces resulted from the new cutting model have a good degreement with measured forces in comparison with these resulted from the existing cutting model

Recent entrepreneurship researches emphasize the importance of entrepreneurial behaviors, entrepreurs activities. This study focused entrepreneurial behaviors, especially entrepreneurial networking for using external resources which are critical to success. This study examines the relationship between characteristics of entrepreneurial networking and performance using data from 55 new high-tech ventures in Korea. We tested hypotheses that the characteristics of entrepreneurial networking are related to the performance of new high-tech ventures using regression analysis and t-test. Major findings of this study are as follows: (1) entrepreneurial networking are related to the performance of new high-tech ventures, (2) significant differences are found in the characteristics of entrepreneurial networking between high and low-performance firms, (3) some factors are related to the entrepreneurial networking. Finally, some managerial and policy implications are presented and future research directions are suggested.

In this paper we propose new primal-dual interior point methods (IPMs) for $P_*(\kappa)$ linear complementarity problems (LCPs) and analyze the iteration complexity of the algorithm. New search directions and proximity measures are defined based on a class of kernel functions, $\psi(t)=\frac{t^2-1}{2}-{\int}^t_1e{^{q(\frac{1}{\xi}-1)}d{\xi}$, $q\;{\geq}\;1$. If a strictly feasible starting point is available and the parameter $q\;=\;\log\;\(1+a{\sqrt{\frac{2{\tau}+2{\sqrt{2n{\tau}}+{\theta}n}}{1-{\theta}}\)$, where $a\;=\;1\;+\;\frac{1}{\sqrt{1+2{\kappa}}}$, then new large-update primal-dual interior point algorithms have $O((1\;+\;2{\kappa})\sqrt{n}log\;n\;log\;{\frac{n}{\varepsilon}})$ iteration complexity which is the best known result for this method. For small-update methods, we have $O((1\;+\;2{\kappa})q{\sqrt{qn}}log\;{\frac{n}{\varepsilon}})$ iteration complexity.

In this paper we propose new large-update primal-dual interior point algorithms for $P_{\neq}({\kappa})$ linear complementarity problems(LCPs). New search directions and proximity measures are proposed based on a specific class of kernel functions, ${\psi}(t)={\frac{t^{p+1}-1}{p+1}}+{\frac{t^{-q}-1}{q}}$, q>0, $p{\in}[0,\;1]$, which are the generalized form of the ones in [3] and [12]. It is the first to use this class of kernel functions in the complexity analysis of interior point method(IPM) for $P_*({\kappa})$LCPs. We showed that if a strictly feasible starting point is available, then new large-update primal-dual interior point algorithms for $P_*({\kappa})$ LCPs have the best known complexity $O((1+2{\kappa}){\sqrt{2n}}(log2n)log{\frac{n}{\varepsilon}})$ when p=1 and $q=\frac{1}{2}(log2n)-1$.

With digitalization accelerated by the 4th industrial revolution, the marine traffic environment is also expected to change rapidly. The purpose of this study was to derive a new service for Aids to Navigation (AtoN) to respond to a new marine traffic environment and suggest service requirements from the perspective of the ship's operator. For this purpose, a survey of ship operators was conducted and IPA analysis was performed. Marine traffic intelligence and information services and Image-based ocean environment information services were deduced as high-priority services from the perspective of ship operators. Thus, the derived results can serve as basic data for developing new AtoN services and determining policy directions.

This study aims at understanding both the mechanism of new town's competitiveness and its normative pursuit. For the purpose the study steps as follows; (1) Defining operationally cities' competitive power by means of analytic interpretation of substantial nature involved in the preceding studies, (2) Finding some lessons for the desirable development suggested from the history of new town construction in England, France and Japan, where the spatial needs for solving urban problems were exploded after the Second World War, (3) Focusing to agendas regarding development, for example, sustainable development, (4) Recognizing differences between competitiveness of cities and that of new towns and finally (5) Building the model of new town competitiveness, which explains what makes the competitiveness and what kind of effort are necessary for acquiring the advantage. As the result of the process this study concludes that the competitiveness is caused by, or composed of 4 factors. They are Self-sufficiency, Identity, Innovativeness and Sustainability. This frame can be named SIIS-model of new town competitiveness. But there should be contingent and elastic approach in adaptation of these factors to a specific new town, considering its own goal, scale and other situation. The model established in this study is expected to be a analytical frame for the follow-up studies on finding problems and seeking directions of new town development in our country.
