  • Information communication environment integrates communication, broadcasting and internet, and Digital Convergence service emerges in result. Thus, the effective routers are needed so that they can transmit a huge number of data to core internet through appropriate base center. Therefore, the network guaranteeing QoS in transport layer supports interoperability with different wireless networks. So as to users receive necessary information anywhere seamlessly, the network architecture focuses on packet transmission and it is efficient for the control layer switches and controls packets between different networks. Since individual users take advantage of different services and data, the effective router architecture must be designed. Hence in this paper we design monitoring technique to solve security problem and to support premium service to ultimate users. Thereafter, we run opnet simulation and show the improvement of proposed router architecture.

  • Considering on the crisis and dilemma of monumentality in Modern architecture, this study analyse the historic reason of decay and new possibility of monumentality within the context of contemporary socio-cultural context. Historically monumentality has been considered as a main substance of High architecture in e tradition of Western Architecture. Difference between building and architecture mainly lies in monumentality which brings about esthetic quality. Usually architects take it granted that the physical and formal characteristics automatically cause the monumentality, But since the modem period the decline of communicative and representative function of architecture made this belief questionable. As Monumentality itself faced the dilemma with the modernity, ironically architects has to response to the task to handle the increasing social demands of monumental building. This study firstly shows the dilemma of monumentality in depth in case of the holocaust museum. Then we analyse the concept of monumentality itself by means of theoretical view of A. Loos and A Riegl We also analyse the change of role which monumental building played in history. Cultural and social change of context, and fundamental change of architecture old way of building a monument impossible. In conclusion this study proposes the new concept and searches new horizon of monumentality with a finding of the otherness of monumentality. Conventional monumental building language has to give way to new approaches. With some examples we already can find a new possibility.

  • All architectures in the history have certain attitudes of aesthetic expression of their own. Depending on the culture, such aesthetic attitudes are not the same but different. This paper aims to identify the nature of the difference of aesthetic attitude in the architectures of the East and the West. As a way of approach for this purpose, two keywords are employed as representative concept. They are: 'proportion' and 'vitality'. Proportion, of course, represent the attitude of the Western, while, vitality, the Eastern. Although these two words are subjective selection, it is hoped that the nature of aesthetic attitudes could be observed through the windows of these two representative concepts. We all know that the architects and students of architecture of this period, are very much concerned about the aesthetic expression of their design. However, the value judgement of aesthetic quality seems quite confused in modem period. If the nature of aesthetic attitudes of the Eastern and the Western architecture is well understood, such understanding will help much for the direction of architectural aesthetic of future architecture.

  • This study was executed to investigate matters connected with planting of Gapho Citizen's Woods(Park), and to offer the data about countermeasure. The study was executed in 1988 and 1989. The contents of the study were the condition of plants, the environmental factors, the states of tree planting and the user's behavior. The result of this study can be summarized as follows. 1. Because of incongruity of soil and regardless of physiological properties of trees, the plants were damaged by their environment. In particular, the stress of soil moisture was serious. 2. The unsuitable planting forms for the park were found out through the park, which was the result of imprudent, additional planting. And so in planting trees additionally, the participation of landscape architect is needed. 3. There is a serious noisy problem from express way. Because when they planted trees, they did not consider about noise. It affected the quality and utilization of the park.

  • Purpose: The purpose of this research is to find out week and strong aspects in LEED categories based on achieved scores earned by LEED-HC(Healthcare) v.2009. Methods: The LEED-HC scorecards of 88 healthcare projects are analyzed. The analysis are focused on relationship between achieved scores, LEED categories and achieved levels. This relationship was presented by graphs and charts. Results: 1) Compare to LEED-NC, in LEED-HC, sub-categories related to public health are added. The scores are added in Energy Atmosphere and Indoor Environmental Quality. 2) Achieve scores in Sustainable Site are high and one in Energy Atmosphere and Indoor Environmental Quality are low at all levels. 3) Scores which was lost in Energy Atmosphere are recovered in Material Resource and Sustainable Site in order to keep its level. 4) Since most of scores in Energy Atmosphere are under EAc1 Optimize energy performance sub-categories, it is important to achieve more score in Optimize Energy Performance Sub-Categories to gain a higher level. Even if LEED-HC has more score in Energy Atmosphere, this is a hard to achieve scores in that categories. It is important to review Energy Atmosphere categories and its points for improvement. Implications: This study will provide basic database in order to establish Korean green building rating system for hospital.

  • In this paper we propose an agent architecture to improve the flexibility of videoconference systems with strategic-INTER knowledge. The proposed architecture achieves more flexibility by selecting dynamically the strategy of QoS (Quality of Service). To select the strategies, the systems have to take into the consideration of the properties of problems occurred on QoS and the status of problem solving process. This architecture is introduced as a part of knowledge base of agent dealing with cooperation between software modules of videoconference systems. We have implemented the architecture and our prototype system shows its capability of flexible problem solving against the QoS degradation, along with other possible problems within the time limitation. We confirmed that the proposed architecture can improve its flexibility of a videoconference system compared to conventional systems.

  • Software reuse gives the meaning for rapid software development and the quality of the software. Most of the Java components/libraries open-source are available only in Java Archive (JAR) file format. When a software design enters into the development process, the developer needs to select necessary JAR files manually via analyzing the given software architecture and related JAR files. This paper proposes an automated approach, JarBot, to suggest all the necessary JAR files for given software architecture in the development process. All related JAR files will be downloaded from the internet based on the extracted information from the given software architecture (class diagram). Class names, method names, and attribute names will be extracted from the downloaded JAR files and matched with the information extracted from the given software architecture to identify the most relevant JAR files. For the result and evaluation of the proposed system, 05 software design was developed for 05 well-completed software project from GitHub. The proposed system suggested more than 95% of the JAR files among expected JAR files for the given 05 software design. The result indicated that the proposed system is suggesting almost all the necessary JAR files.

  • Emerging high broad band multimedia service with high quality has led to demand for challenge of optical access network and Passive Optical Network is one of the most important technologies for future optical access network. In this paper, we study the scheduling algorithm for WDM-PON in SUCCESS network architecture, a next generation hybrid WDM/TDM optical access network architecture. Due to economic implementation of this architecture, the shared resources efficiently need to be assigned and then we propose the efficient scheduling algorithm based on specific architecture and characters of SUCCESS. We evaluate and analyze the performance in terms of the average packet delay and throughput of the whole system.

  • In order to provide new value-added services such as a policy-based routing and the quality of services in next generation network, the Internet routers need to classify packets into flows for different treatments, and it is called a packet classification. Since the packet classification should be performed in wire-speed for every packet incoming in several hundred giga-bits per second, the packet classification becomes a bottleneck in the Internet routers. Therefore, high speed packet classification algorithms are required. In this paper, we propose an efficient packet classification architecture based on a hierarchical binary search fee. The proposed architecture hierarchically connects the binary search tree which does not have empty nodes, and hence the proposed architecture reduces the memory requirement and improves the search performance.
