  • In this paper, a new high performance data cache scheme that improves exploitation of both the spatial and temporal locality is proposed. The proposed data cache consists of a hardware prefetch unit and two sub-caches such as a direct-mapped (DM) cache with a large block size and a fully associative buffer with a small block size. Spatial locality is exploited by fetching and storing large blocks into a direct mapped cache, and is enhanced by prefetching a neighboring block when a DM cache hit occurs. Temporal locality is exploited by storing small blocks from the DM cache in the fully associative buffer according to their activity in the DM cache when they are replaced. Experimental results on Spec2000 programs show that the proposed scheme can reduce the average miss ratio by $12.53%\sim23.62%$ and the AMAT by $14.67%\sim18.60%$ compared to the previous schemes such as direct mapped cache, 4-way set associative cache and SMI(selective mode intelligent) cache[8].

  • A static aeroelastic analysis for supersonic aircraft wing equipped with external store under the wing lower surface is performed using computational fluid dynamics (CFD) and computational structural technology(CST) coupling methodology. Two mapping algorithms, which are the pressure mapping algorithm and the displacement mapping algorithm, are used for CFD/CST coupling. A three-dimensional unstructured Euler code and finite element analysis program are used to calculate the flow properties and the structural displacements, respectively. The coupling procedure is repeated in an iterative manner until a specified convergence criterion is satisfied. Static aeroelastic analysis for a typical supersonic flight wing is performed and final converged wing configuration is obtained after several iterations.

  • This study is an effort to develop a stochastic model of precipitation series that preserves the pattern of occurrence of precipitation events throughout the year as well as several characteristics of the duration, amount, and intensity of precipitation events. In this study an event cluster model is used to describe the occurrence of precipitation events. A logarithmic negative mixture distribution is used to describe event duration and separation. The number of events within each cluster is also described by the Poisson cluster process. The duration of each event within a cluster and the separation of events within a single cluster are described by a logarithmic negative mixture distribution. The stochastic model for hourly precipitation occurrence process is fitted to historical precipitation data by estimating the model parameters. To allow for seasonal variations in the precipitation process, the model parameters are estimated separately for each month. an analysis of thirty-four years of historical and simulated hourly precipitation data for Seoul indicates that the stochastic model preserves many features of historical precipitation. The seasonal variations in number of precipitation events in each month for the historical and simulated data are also approximately identical. The marginal distributions for event characteristics for the historical and simulated data were similar. The conditional distributions for event characteristics for the historical and simulated data showed in general good agreement with each other.

  • Generally, the events in nature have multi-disciplinary characteristics. To solve this problems, these days loosely coupled methods are widely applied because of advantage of solvers which are already developed and well proved. Those solvers use different mesh system, so transformation and mapping of data are vital in the field of fluid-structure interaction(FSI). In this paper, the interpolation of deformation which is used globally and compactly supported radial basis functions(RBF), and mapping of force which use principle of virtual work are examined for computing time and accuracy to compare ability with simple 3-D problem. As the results, interpolation scheme of compactly supported radial basis functions are useful to interpolation and mapping for large-scale airplane in FSI with a k-dimensional tree(kd-tree) which is a space-partitioning data structure for organizing points in a k-dimensional space.

  • This study aims to generalize the stream network developing algorithm of the geographic hierarchy Stream networks with hierarchy system should be spatially hierarchized in linear features. The generalization procedure of the stream networks are composed of the hierarchy of stream, selection and elimination, and algorithm. Working of stream networks is composed by the decision of direction on stream networks, ranking of stroke segments, and ordering by the strahler method, using geographic data query for controlling selection and elimination of the linear feature by scale. Improved Simoo algorithm was effective in enhancement and decreasing curvature of linear features. Resultantly, it is expected to improve generalization of features with various spatial hierarchy.

  • The current research investigates the basic philosophy that would serve as a foundation for the development of the service economy. In particular, the current work suggests that the Korean traditional philosophy fits the philosophy of the service economy because of the relational nature of the Eastern culture (vs. Western culture). Therefore, it is suggested that trough manifestation of the Korean traditional philosophy, the service economy would be invigorated. The yin-yang and the Two Taegeuk do not emphasize the role of human, and thus, a new philosophy incorporating this aspect needs closer attention. Therefore, the Korean traditional philosophy, structured in a Three Taegeuk framework could serve as the foundation for the development of the service economy. The Three Taegeuk framework relates to the harmonization, horizontality, bi-directionality, and relational aspects of the service industries. For example, human serving the agent role in the society resembles the current service economy where service workers and customers serve important roles in value creation. Taken together, the current research suggests that the Korean traditional philosophy serve as an important foundation for the development of the service economy.

  • This paper is an attempt to find commonality and complementarity between psychanalysis and Daesoon thought, while understanding the practical meaning of the Haewon-Sangsaeng, which is one of the religious doctrines of Daesoon Jinrihoe, in terms of the theory of desire posited by psychoanalysis. There is a common point between Daesoon thought and psychoanalytic theory since both ideas give importance to desire. The Haewon idea is similar to that of psychoanalytic theory, which emphasizes restoring desire through mourning and realizing it within a structure of inter-subjectivity. Of course, the meaning of desire in Daesoon thought, given its status as a religious doctrine, is polysemous, and the orientation of this type of desire is also different from that of psychoanalysis given psychoanalysis's role as a therapeutic discourse. However, Daesoon thought explains that the pain and unhappiness suffered by human beings occurs because of mutual overcoming which is a relational style wherein desire can not be solved properly for either party involved in an interaction. Mutual overcoming is a state of mutual beneficience beyond the previous state of mutual overcoming. Likewise, psychoanalysis seems to accept the loss of the object through mourning, and in this way, desire is reactivated. Daesoon thought emphasizes the importance of social and cosmic systems like mutual beneficience and the reordering of the Universe and these systems have a commonality with psychoanalysis as psychoanalysis sees desire positively within the structure of inter-subjectivity. The direction of social practice in Daesoon thought and psychoanalysis both aim at the realization of a new universality. The inter-subjectivity structure suggests desire of recognition and recognition of desire as a way of practice because desire is not personal but rather social. In conclusion, we should not stop at resolving our own individual desires, but should instead go forward in solidarity toward the achieving the common good.

  • A color gamut mapping has been known to be one of promising methods to enhance display quality of various types of color display device. However, it is required to handle this mapping in real time for display or digital TV application. If carefully arranged, the tetrahedral interpolation can be computed with simpler operations compared to a cubic interpolation in the conventional reduced resolution look-up table which is devised to process the gamut mapping in real time. Based on the tetrahedral interpolation, a new type hardware architecture for real-time gamut mapping is proposed in this paper. The proposed hardware architecture shows better processing speed and reduces the hardware cost.

  • 서명응의 "중용경위"는 '심은 태극이자 중이며, 또 "하도"의 중궁'이라는 선천학의 심법을 제시한다는 점에서 기존의 "중용"해석과 차이를 보인다. 다른 특징으로는 "중용경위"의 구성 체제가 독창적이라는 점이다. 더불어 이러한 체제와 그 내용이 "하도"와 긴밀히 연결된다는 점이다. 서명응은 "중용"의 구조와 서술방식이 선후천의 법상에 따라 서술된 것으로 본다. 이를 입증하기 위해 서명응은 통행본 "중용"의 33장 체제를 32장으로 재구성한다. 그리고 그는 이 총 32장의 전체 구성이 '태극-양의-사상'으로 전개되는 "선천도"의 구조와 같고, 개별 장들이 서로 '대대' 관계로 되어 있는 구조는 선천의 '대대' 구조와 같으며, 각 장 안의 문장에서 구와 절들이 '반대' 관계로 되어 있는 것은 후천의 '반대' 구조와 같다고 본다. 서명응이 제시한 이러한 선천의 구조는 결국 "하도"로부터 연역되어 나온 것이다. 또 그 안에 담긴 심으로 천명의 중을 체인하는 사상이 "하도"와 연결된다고 파악한다.
