Context-aware computing systems require real-time context reasoning process for context awareness. Context reasoning can be done by comparing input information from sensors with knowledge-base within system. This method is identical with it of rule-based systems. In this paper, we propose hardware rule-based system architecture which can process context reasoning in real-time. Compared to previous architecture, hardware rule-based system architecture can reduce the number of constraints on rule representations and combinations of condition terms in rules. The modified content addressable memory, crossbar switch network and pre-processing module are used for reducing constraints. Using SystemC for description can provide easy modification of system configuration later.

The Purpose of this study is to look for the total conspectus of Roo-Jong(RJ) Architecture in the middle and latter era of Koryo Dynasty. The method of this study is the review of old literature, the Roo-Jung description of Dong-Mun-Sun, which had compiled in the Ninth year of Seung-Jong (AD 1478) by confucian scholar. The conclusions of this study can be summarized as follows : 1) The main currents of thought having a great influence on the RJ are thought of Mountain God (or Sin Sun, which is dwelling in mountain) or Taoist, thought of Lao-tzu and Chuang-tzu. They had required the RJ Architecture to pursuit the life of God. In this existence value meaning, the RJ Architecturethe is the semi-sacred & profane space. In the being aspect, RJ is the transcendental architecture. 2) The way of life of in the RJ had strongly turned from the personal space, mainly mind control place, into the friendship-society space, pastime place. 3) The RJ had located after the images that is what should be. The images were formed on the ground of natural landscape elements, communication elements. And these elements were indicated on one's visual, auditorial sensation with oneself. 4) In planning aspect, the scope of visual, Pungsu and history were aided with the factors of climate, topography and geography. Specially in location and fabric planning, they had regarded more important the objects and scope of visual than the climate factor.

We study, in this paper, on the decorative design of the Treasure-architectural form for the Silla Buddhist reliquary and this research went through the observation on the Buddhist Reliquaries of the Song-Lim-Sa, the Eastern-Western three floor pagodas in the Kam-Eun-Sa, the three floor pagodas in the Bul-Guk-Sa and the reportedly discovered Nam-Won. The Buddhist reliquaries of these 5 Reliquaries, when compared with those of China and Japan in the same period, they worshiped the Buddhist reliquary as a Buddhist God itself and put them as a part of the architectural decoration, being installed in the construction forms. In the form and the composition of the architecture, we can see those having been designed with very detailed and brightly decorated form. The Buddhist reliquaries in the Song-Lim-Sa and Kam-Eun-Sa, the most important ones in this research, were in a royal palace shape having completely the altar part, interior space part, and the ceiling part, which inform us the whole structure of the architecture in details. In particular, for the case of Kam-Eun-Sa, the columns in the shape of bamboo trees, the expression of the gates, the terrace of double parts formed of word-shape Man, and the statue of a general with superhuman ability in the shrine explain us the description of the Gyun-Bo-Tap-Pum of Lotus Sutra. After all these researches, we conclude that the Buddhist reliquaries in form of the Treasure-architecture represented the architectural style of the same period as a form of industrial arts and we can see that they tried to use all of their highly skilled and talented methods to describe the Buddhist Pure Land.

In this paper, the CAD data for the optimal shape design obtained by isogeometric shape optimization is directly used to fabricate the specimen by using 3D printer for the experimental validation. In a conventional finite element method, the geometric approximation inherent in the mesh leads to the accuracy issue in response analysis and design sensitivity analysis. Furthermore, in the finite element based shape optimization, subsequent communication with CAD description is required in the design optimization process, which results in the loss of optimal design information during the communication. Isogeometric analysis method employs the same NURBS basis functions and control points used in CAD systems, which enables to use exact geometrical properties like normal vector and curvature information in the response analysis and design sensitivity analysis procedure. Also, it vastly simplify the design modification of complex geometries without communicating with the CAD description of geometry during design optimization process. Therefore, the information of optimal design and material volume is exactly reflected to fabricate the specimen for experimental validation. Through the design optimization examples of elasticity problem, it is experimentally shown that the optimal design has higher stiffness than the initial design. Also, the experimental results match very well with the numerical results. Using a non-contact optical 3D deformation measuring system for strain distribution, it is shown that the stress concentration is significantly alleviated in the optimal design compared with the initial design.

The purpose of this study is to investigate Seonyudo Park and Kkummaru in terms of haptic space. This is an attempt to escape from the limits of optical space that identifies the space with abstract concepts. Haptic perception of the space refers to feeling the space with all the senses through non-hierarchical interactions. Time of the haptic space is revealed by Deleuze's crystalline description and Bergson's pure recollection that is not useful to identify objects. According to two concepts, the running present forks into the past and the future, and the nature of time appears at the point of indiscernibility in which the past, present, and future coexist. Thought on time about the architecture provides a valid point of view to understand the relationship of visitor's sensory experience of space, recollection, and emotion. In this respect, it can be said that Joh sung-yong's two works explored for new areas of architectural experience by building up the potential image of the subject which is placed in the human memory. And then this study shows that two works recover the relationship between the past and the present so that they give an opportunity to consider the meaning of time in the architecture.

This study attempts to identify the level of conflicts occurring between foreign and domestic chefs, and to suggest the way of controlling those conflicts in order to well manage human resources, foreign chefs. Based on the empirical research, the research findings shows that in terms of targeting and achieving objectives different level of conflicts are experienced when age, hotel type, position varies. For example. purchasing excessive foreign foods may cause undesirable stock which will lead to considerable loss. In order to overcome this problem the advantages of the chain-operated and the independent hotel's food purchasing system must be incorporated. Secondly, another conflicts arise when the architecture and system of a kitchen is different from what foreign chefs are familiar with. Kitchen architecture and system should be well-designed in terms of delivery channel, sanitation, safety, food control, banquet etc.. In developing menu, chefs often have different criteria in the scale of sweet and salt of a particular dish. Foreign chefs often blame his subordinates for not meeting his requirements without proper training or education. Finally, because of the different culture, communication as well as the lack of mutual understanding problem occur. Even though today is called global town. some chefs do not seem to open their minds to learn other developing countries' culture. In diversity management aspect, chefs need to put much effort to be aware of other countries' culture, history, political and economic situation. In prior to employing foreign chefs, the job enrollment and description must be prepared so as to minimize the conflicts, which otherwise will create poor job performance.

In this paper, a low-complexity and low-power soft output multiple input multiple output (MIMO) symbol detector is proposed for mobile devices with two transmit and two receive antennas. The proposed symbol detector can support both the spatial multiplexing mode and spatial diversity mode in single hardware and shows the optimal maximum likelihood (ML) performance. By applying a multi-stage pipeline structure and using a complex multiplier based on the polar-coordinate, the complexity of the proposed architecture is dramatically decreased. Also, by applying a clock-gating scheme to the internal modules for MIMO modes, the power consumption is also reduced. The proposed symbol detector was designed using a hardware description language (HDL) and implemented using a 65nm CMOS standard cell library. With the proposed architecture, the proposed MIMO detector takes up an area of approximately $0.31mm^2$ with 183K equivalent gates and achieves a 150Mbps throughput. Also, the power estimation results show that the proposed MIMO detector can reduce the power consumption by a maximum of 85% for the various test cases.
