In this paper, we consider a two-dimensional fractional space-time diffusion equation (2DFSTDE) on a finite domain. We examine an implicit difference approximation to solve the 2DFSTDE. Stability and convergence of the method are discussed. Some numerical examples are presented to show the application of the present technique.

The sequence spaces $c^F$(M), $c^F_0$(M) and ${\ell}^F$(M) of fuzzy real numbers with fuzzy metric are introduced. Some properties of these sequence spaces like solidness, symmetricity, convergence-free etc. are studied. We obtain some inclusion relations involving these sequence spaces.

In this work, the three-step intermixed iteration for two finite families of nonlinear mappings is introduced. We prove a strong convergence theorem for approximating a common fixed point of a strict pseudo-contraction and strictly pseudononspreading mapping in a Hilbert space. Some additional results are obtained. Finally, a numerical example in a space of real numbers is also given and illustrated.

U-City 서비스로 대표되는 첨단 공간서비스는 그동안 10여년의 많은 노력과 예산투자의 결과로 가시화된 국토정보화(National Digitalization)의 결실로서 평가될 수 있다. U-City서비스는 정보통신기술을 근간으로 하고 있으나 현실공간의 지능화 측면에서 그 개념상 공간정보와 또 그것을 기반으로 국토공간을 분석하고 활용하기 위한 국토 공간계획과 긴밀한 연계관계를 갖지 않을 수 없다. 그러나 아직까지 U-City서비스는 기존의 공간정보 및 공간계획과 명확한 상호관계 설정 및 각 분야간 계획, 구축 및 관리간 연계가 미흡한 실정에 있다. 따라서 본 연구의 주요 목적은 디지털융합시대의 국토 유비쿼터스화라고 하는 큰 명제하에 U-City서비스가 국토 공간정보 및 공간계획과 상호 유기적 연계관계를 가지고 발전할 수 있도록 하기 위한 디지털융합공간(Digital Convergence Space)의 신개념을 제안하고 그 구현을 위한 제도적 정비방안을 제시하는데 있다.

This study is for getting sacrificial service, discussing process of sacrificial rituals and understanding the composition of space in Dong-gok Jaesa. For these things, we're arranged for exact blueprint through actual survey and analyzed the architectural features. Dong-gok Jaesa has features which show centripetal space organization with strong closing sparsely. This is intended for sincerity during ritual which is processed without obstruction. This is a mixed form which is unified both straight dwelling and Jung Dang Hyeop Sil type. And this is for all functions which is necessary for Jaesa architecture in only one building. And this is used with organizing technique for space utility with connection of compartments and various enlargement and partition. Through these things, even though it is not a big Jaesa, it shows that this is Korea traditional composition of space technique according to several purposes.

The purpose of this study was to investigate its characteristics of the spatial compositions at several kindergartens in Daegu area. Through this, the study is intended to provide the basic data of the efficient building planning and facility operations in the kindergarten. The results of this study are as follows. 1) Recently, the spatial compositions of kindergarten was classified as education, educational aids, educational support, teacher / administration, and public service area. 2) The concept of special classroom space was set up in all the surveyed facilities. This space was used for small-scale events, meals, and game features. 3) Support staff, including teachers, are insufficient for the service space. 4) The size of total land area of the facility's public service area was affecting. 5) The Lobby and aisle space of the surveyed facilities was used as a multipurpose space. 6) In response to diverse educational content, the direction to plan should be seperated by multi-space.

A convergence structure defined by Kent [4] is a correspondence between the filters on a given set X and the subsets of X which specifies which filters converge to points of X. This concept is defined to include types of convergence which are more general than that defined by specifying a topology on X. Thus, a convergence structure may be regarded as a generalization of a topology. With a given convergence structure q on a set X, Kent [4] introduced associated convergence structures which are called a topological modification and a pretopological modification. (omitted)

In this study, we present a multi-sensor module for snake robot searching survivors in a narrow space. To this end, we integrated five sensor systems by considering the opinions of the first responders: a gas sensor to detect CO₂ gases from the exhalation of survivors, a CMOS camera to provide the image of survivors, an IR camera to see in the dark & smoky environment, two microphones to detect the voice of survivors, and an IMU to recognize the approximate location and direction of the robot and survivors. Furthermore, we integrated a speaker into the sensor module system to provide a communication channel between the first responders and survivors. To integrated all these mechatronics systems in a small, compact snake head, we optimized the positions of the sensors and designed a stacked structure for the whole system. We also developed a user-friendly GUI to show the information from the proposed sensor systems visually. Experimental results verified the searching function of the proposed sensor module system.

이 논문은 중국과 일본의 상이한 미적, 철학적 차이의 이해와 융합을 기반으로 그래픽 디자인 분야에서 여백을 통한 새로운 표현 창출을 위한 방법에 대해 논했다. 그래픽 디자인에서 동양의 특징적인 여백을 표현하는 것은 디자인의 예술적 표현과 문화적 의미를 풍부하게 하고 디자인의 창작의 가능성을 높을 수 있다. 이 연구에서는 먼저, 중국과 일본의 미술 및 디자인에서의 여백에 대한 인식과정과 표현과정을 중국의 전통회화의 철학과 일본의 현대 그래픽 디자인의 방법이 적용된 포스터 디자인을 통해 비교∙분석한다. 이를 기반으로 포스터 디자인에서 여백을 통해 중국 현대 그래픽 디자인의 새로운 접근방법으로써 융합의 개념을 적용해 그래픽 작업에서의 표현의 가능성을 확장한다. 또한, 여백에 대한 융합적 개념에 의한 표현 창출은 자신의 작품에 새로운 가능성을 제공한다.

Traditional architectural space, which is a historical cultural heritage must be connected mutually as a organic flow of various elements such as the environment of the time, political background and values, rather than approaching with fragmentary point of view. The Silhak Philosophy, the basis of late Chosun society developed equity thoughts on the basis of ideology of humanism, and it asserted the promotion of technology and industry as a measure to realize the pursuit of truth which is practically useful. Thus, we could verify the possibility of convergent interpretation of cultural technology of Hwaseong architectural space through the humanistic viewpoint of pioneer spirit of Silhak Philosophy which regards human as a main agent of desire of life, and the pursuit of truth which is useful for reality, and the realization of ethical value by aesthetic practicalism. Based on this, the ontological meaning and value of Suwon Hwaseong by the viewpoint of convergence of culture and technology have been drawn as the construction of planned new town by the practice of filial duty, the plan of city space based on rational values, the realization of a metropolis where self-sufficient economic activities are possible, the introduction of thorough construction management system, the introduction of advanced culture and its creative application, and the application of scientifical knowledges and cutting-edge technology.
