  • In this paper, we give a Peleg type KKM theorem on G-convex spaces and using this, we obtain a coincidence theorem. First, these results are applied to a whole intersection property, a section property, and an analytic alternative for multimaps. Secondly, these are used to proved existence theorems of equilibrium points in qualitative games with preference correspondences and in n-person games with constraint and preference correspondences for non-paracompact wetting of commodity spaces.

  • In contemporary design conditions, the focus of landscape architecture has shifted from 'form' to 'process.' Various experimental diagrams have been proposed to overcome the limitations of conventional form-oriented landscape design. This study aims to reconsider theoretically and critically the modes and mechanism of diagrams in recent landscape architectural design. It also explores the operational capabilities of diagram in design process. Although the traditional diagram has served as explanatory and representational graphics in design, contemporary designers emphasize the generative function of diagram on the basis of Gilles Deleuze's theory of 'diagram as abstract machine.' They manifest and practise that diagrams call generate forms and proliferate spaces in their design development. This paper examines current examples of generative and constructive diagrams produced by leading designers. However, the author illuminates another significance of diagram: the diagram as strategic media of design. Contemporary environments and conditions of design, such as the complexity of city and the interactivity of new economy, call for new design intelligence and strategic design. These situations require alternative media in design process. In this context, the diagram can function as strategic media of dynamic and flexible design. This is why contemporary landscape theory and practice have to give attention to diagrams.

  • Recently, Kazmi and Khan [7] introduced a kind of equilibrium problem called generalized system (GS) with a single-valued bi-operator F. Next, in [10], the first author considered a generalization of (GS) into a multi-valued circumstance called the multi-valued quasi-generalized system (in short, MQGS). In the current work, we provide an extension of (MQGS) into a system of (MQGS) in general settings. This system is called the generalized multi-valued quasi-generalized system (in short, GMQGS). Using the existence theorem for abstract economy by Kim [8], we prove the existence of solutions for (GMQGS) in the framework of Hausdorff topological vector spaces. As an application, an existence result of a system of generalized vector quasi-variational inequalities is derived.

  • This study aim to do observation to 1) Trajectory of cognitive-cultural economy growth with regional historical context, 2) Spatial, cultural and social change caused by cognitive-culture economy growth, and 3) Draw the meaning of the change in glocalizational view. They said that 'Creativity' has been related with spatial, economical, cultural and social change and it leads to new economical system, what we call 'Cognitive-cultural economy'. It is the important event which is to affect economic geography and local development greatly. New cultural changes are characterized by variations from abstract discourse to concrete reality and show the emphasis on real project specific in the region. Further more, possibility of local development in the glocalization found in the specific form of cultural content, for example, Korean Wave. New media environment changes that include SNS function not only interact each other in space but also expand the scope of local units and cultural content to the world. In order to enhance the further development of local content, it will require conjunction with space and specific region, variety of organic link between the principal participants, and building infrastructure for future development.

  • The purpose of this study was to investigate how formativeness of shamanism has expressed and developed in modern fashion. Formative expression of shamanism in modern fashion has expressed in the way of on style, color, material and pattern as follows; Style has made animal and human incorporated by expressing abstract animal on the part or whole of costume and it has reconstructed traditional shaman costume into modern costume. Skin colors of living bodies which exist in nature, such as black, blown, yellow and grey, were used to symbolize spirit and low brightness of colors such as blue, white and black were also used to symbolize hyperspace. Artificial materials which imitate animal figure and genuine materials from animal were used. Various natural materials used in traditional shaman costume were also used. Animal patterns and abstract patterns symbolizing the celestial heaven and lower world, and patterns shown on wall painting and rock painting has appeared. The meaning of shamanism in modern fashion can be identified as interchangeable movement of time and space, a cosmic outlook on the world and ration. Spiritually designed costume has made fashion move to hyperspace in spirit trip. Modern fashion with shamanism has expressed its cosmic outlook on the world or universal wish beyond human's real world by patterns such as bird figure which means the celestial heaven and lower world. Corporation and transition of human and animal were symbolized as shaman hypernatural intercourse with designs expressed in costume using a part of animal or animal's characteristics.

  • This study aimed at learning the effect of farmers' individual competency on the performance of agricultural organization, and providing the preliminary data about strengthening the competitiveness of agriculture of the country by showing the effect of farmers' individual competency on the performance of agricultural organization. According to the results of our study, among 11 individual competencies, the ability to manage, customer satisfaction, marketing, and getting information have the positive relationship with the performance of agricultural organization, but strategic thinking has the negative relationship with the performance. The relationship between the performance and abstract competencies like teamwork, creativity, innovation, feasibility, and flexibility is not statistically significant. However, the abstract competencies are the core competencies within farmers, so farmers should be educated continuously in the long run in order to raise the performance.

  • Since the mitigation of fear of crime significantly enhances the consumptions in a city, studies focusing on urban safety analysis have received much attention as means of revitalizing the local economy. In addition, with the development of computer vision and machine learning technologies, efficient and automated analysis methods have been developed. Previous studies have used global features to predict the safety of cities, yet this method has limited ability in accurately predicting abstract information such as safety assessments. Therefore we used a Convolutional Context Neural Network (CCNN) that considered "context" as a decision criterion to accurately predict safety of cities. CCNN model is constructed by combining a stacked auto encoder with a fully connected network to find the context and use it in the CNN model to predict the score. We analyzed the RMSE and correlation of SVR, Alexnet, and Sharing models to compare with the performance of CCNN model. Our results indicate that our model has much better RMSE and Pearson/Spearman correlation coefficient.

  • It is an objective of Shanghai urban development to quickly build Shanghai into one of the international centres of economy, finance and trade. To fulfil the objective, a rational urban general layout and a satisfactory traffic network are needed. As a metropolis with complete urban functions and specified geographical position, Shanghai must develop a perfect citytown system that best suits its composite urban distribution. In planning the central city, the principle of "open and multi-centred" and "optimization of land use" should be taken into consideration. To build a satisfactory urban traffic network, emphasis should be laid upon the construction of deefwater wharf, air-field and inforation centre. In addition, determination should be made to build a high-speed traffic means including high speed railroad and express highway so that a public traffic network is realised on and above ground, and underground. A solution of traffic preblem in Shanghai lies in good understanding of traffic policy and strenthening of strategic management combined with a rational layout of traffic circulation.
