Until now, the eco-friendly construction (green construction) has been focused on reducing environmental impacts in use(operation and maintenance) phase. Considering the environmental influence along the life cycle of construction project, the impact in execution phase is rather lower than that in use phase. However, that impact is thought to be greatly decreased by well-organized activities. Based on its urgency and requirement for timely action, this study aimed to discuss the greenhouse gas (GHG) reduction plan in execution phase from a broad perspective. To achieve this purpose, the green building rating systems in domestic and foreign countries have been reviewed, and the practice in Japan was investigated. In order to improve current on-site greenhouse gas management, the integration among construction phases, participants, and environmental factors, and institutional supports are required as well as the contractor's efforts.

This paper improves top-down execution models of logic programs based on a two-phase abstract interpretation which consists of a bottom-up analysis followed by a top-down one. The two-phase analysis provides an approximation of all (possibly non-ground) success patterns of clauses relevant to a query. It is specialized by considering Sato and Tamaki’s depth k abstraction as abstract function. By the ability of the analysis to approximate possibly non-ground success patterns of clauses relevant to a query, it can be statically determined whether some subgoals will fail during execution and some succeeding subgoals do not participate in success patterns of program clauses relevant to a given query. These properties are utilized to improve execution models. This approach can be easily applied to any top-down (parallel) execution models. As instances, it is shown to be applicable to linear execution model and AND/OR Process Model.

In this paper has been developed a process model for the international technical cooperation. Model consists of five steps: Beginning phase, Partner search phase, contract phase, execution phase and exit phaseInthe beginning phase. The industries need to know about their own require and in the partners search phase they have difficulty navigating partner and to find the fit partner. In agreement phase the industries have problme with international law and in the execution phase they have cultural difficulties. Therefore, the government may need to seek support programs for each step.

In this paper, we suggest a message-based communication protocol and a dynamic role assignment mechanism for efficient cooperation and teamwork of agents in computer game environments. This role assignment mechanism is a new one different from both existing static and dynamic mechanisms, in which all decisions related with role assignment are made at once in design phase or execution phase. According to our mechanism, all possible role sets are determined in design phase. Detail decisions regarding which agent takes what role, however, are made in execution phase. This mechanism for role assignment can minimize the negotiation effort in execution phase. Therefore, this mechanism is quite effective especially in real-time multiagent environments. Through experiments, we show the superiority of the new dynamic role assignment mechanism.

Schedulability analysis is necessary to build reliable embedded real-time systems. For schedulability analysis, worst-case execution time(WCET) analysis that computes upper bounds of the execution times of tasks, is required indispensably. WCET analysis is done in two phases. The first phase is high-level analysis that analyzes control flow and finds longest paths of the program. The second phase is low-level analysis that computes execution cycles of basic blocks taking into account the hardware architecture. In this thesis, we design and implement integrated WCET analysis tools. We develop the WCET analysis tools for XScale-based system called WATER(WCET Analysis Tool for Embedded Real-time system). WATER consist of high-level flow analyzer and low-level execution time analyzer. Also, We compare real measurement for execution of program with analysis result calculated by WATER.

President Lee, Syngman was ROK supreme commander at the Korean war. But, it is doubt that he executed his authority and responsibility by the ROK constitution and law. At the phase of the Korean War conduct, his role may be divided into 'military operation execution one' and 'political-diplomacy one'. He appointed unqualified person to the important position of the national defence, didn't make war execution system, and was not make to meet the war. And, after transferring the ROK force operation commanding authority to the Commander in Chief, UN Command, his role was extremely trivial at the military operation execution phase. Any way, he intended to recover the inferior national strength and military capacity with USA aid, and concentrated his effort toward diplomacy with USA. At last, he succeeded in making a mutual defence treaty and gained a big result to harden Korea national security after war. In sum, president Lee was shrewd politician and diplomat than military leader. And, it can be evaluated that he supplemented the lost part of military affairs side with diplomat one.

Parametric design is an important modeling paradigm in CAD/CAM applications, enabling efficient design modifications and variations. One of the major issues in parametric design is to develop a geometric constraint solver that can handle a large set of geometric configurations efficiently and robustly. In this appear, we propose a new approach to geometric constraint solving that employs a graph-based method to solve the ruler-and-compass constructible configurations and a numerical method to solve the ruler-and-compass non-constructible configurations, in a way that combines the advantages of both methods. The geometric constraint solving process consists of two phases: 1) planning phase and 2) execution phase. In the planning phase, a sequence of construction steps is generated by clustering the constrained geometric entities and reducing the constraint graph in sequence. in the execution phase, each construction step is evaluated to determine the geometric entities, using both approaches. By combining the advantages of the graph-based constructive approach with the universality of the numerical approach, the proposed approach can maximize the efficiency, robustness, and extensibility of geometric constraint solver.

The object of this study is to elicit major success factors along with the phases of implementing the BPR in case of public corporations. To obtain the goal of this research, (1) this study reviews and integrates the major previous BPR studies and shows critical success factors of implementing BPR projects coincided with the characteristics of the public organizations. (2) This study has analyzed and arranged the details of BPR projects of public corporations in South Korea through the literature survey, the questionnaire and the interview. (3) This study classifies 40 critical success factors which were identified in existing studies into ones belonging to 3 phases of BPR projects implementation: Introduction Phase, Execution Phase and Stabilization Phase. (4) This study has tested the relation between critical success factors on each stage of BPR projects implementation and the performance variables. It has proven that there is the statistically significant correlation between the success factors and the performance. The findings of this study are thought not only to be useful as a practical guideline in carrying out BPR project Implementation but also to provide significant basis for constructing the theoretical framework of effective BPR project implementation strategy.

This paper describes RISC core that has been designed for embedded and protable applications such as PDA or PCS. This RISC processor offers low power consumption and fast context switching. Processor performance is improved by using conditional instruction execution, block data transfer instruction, and multiplication instruction. This architecture is based on RISC principles. The processor adopts 3-stage instruction execution pipeline and has achieved single cycle execution using a 2-phase 40MHz clock. This results in a high instruction throughput and real-time interrupt response. This chip is implemented with $0.6{\mu}m$ triple metal CMOS technology and consists of about 88K transistors. The estimated power dissipation is 179mW.
