  • 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.

  • 본 논문은 지역의 역사적인 맥락을 중심으로 인지문화경제의 발전으로 이어지는 궤적을 살펴보고, 이에 따른 공간적 변화 및 문화 사회적 변동을 '글로컬라이제이션'이라는 주제로 관찰하고 함의점을 알아보고자 한다. 이때 특히 최근 창조경제에서 중요한 '문화콘텐츠'분야에 집중하고자 한다. 오늘날 대두되고 있는 '창조성'은 이미 오래전부터 공간 경제 사회문화적인 변화의 관련성과 깊은 연관을 맺어왔다고 할 수 있으며, 이것이 '인지문화경제'라고 하는 새로운 경제체제로 변화하기 시작했다고 할 수 있다. 이는 경제지리와 지역발전에 깊은 영향을 미치게 되며, 특히, 지역발전을 주도하게 된다. 이러한 맥락에 따른 문화변동의 특징은 재현과 이미지의 해석 등 추상적인 담론에서, 지역단위에서 실제적으로 일어나는 프로젝트로 등으로 대변하게 되며 보다 구체적인 특징을 지니게 된다. 더 나아가 글로컬라이제이션 시대의 지역발전의 가능성은 한류와 같은 문화콘텐츠를 통해 확인할 수 있다. SNS 등과 같은 현대 미디어의 환경은 서로 소통하는 공간의 기능뿐만 아니라 로컬 단위의 콘텐츠를 전 세계로 확대할 수 있는 역할을 담당하면서 공간을 확대시키고 있다. 향후 글로컬 콘텐츠의 보다 높은 가능성을 위해 공간과 지역의 연계 강조, 다양한 주체들의 유기적인 연계와 활성화, 로컬 단위의 발전성을 담보하기 위한 인프라 구축 등의 주기적인 노력이 수반되어야 할 것이다.

  • 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.

  • 본 연구의 목적은 농업인의 개인역량이 농업인이 속한 조직의 성과에 얼마나 영향을 미치며, 조직성과에 큰 영향을 주는 개인역량의 도출을 통해 농업조직의 성과 향상을 통한 국내농업의 경쟁력제고에 기초자료를 제공하고자 하였다. 본 연구 분석결과 11개의 농업인 개인역량 중 "관리능력, 고객만족, 마케팅, 정보획득"은 조직성과에 정(+)의 영향을 미치는 것으로 나타났으며, "전략적사고"는조직성과에 부(-)의 영향을 미치는 것으로 분석되었다. 또한, 다소 예측하기 힘든 추상적 역량인 "팀워크, 창조성, 혁신성, 실행성, 유연성"은 통계적 유의성이 없는 것으로 나타났으나, 농업인들에게 내재되어 있는 중요 역량으로 조직성과 향상을 위해 장기적이고 지속적인 교육을 통한 농업인 개인역량 강화가 필요할 것으로 판단된다.

  • 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.
