Environmental pollution has become a serious worldwide problem the humans has encountered in several decades. On the respect of the preservation of the global environment, world-wide consensus to cope with this problem was represented as 1992's Rio Declation. The purpose of this study is to develope evaluation technique of ecological architecture. The environmental scores of the buildings are evaluated and improved from the building design phase in order to build the best environmental building. Ecological architecture is mainly based on the balance of three element : Nature, Humanity, and Cost saving. Its main goals are energy saving and recycling, resource saving, high contact with circumstances, and health & amenity.

This paper is to explore that there are structural problems in the Korea-U.S. Free Trade Agrement negotiation by examining the Korean FTA policy and to introduce some alternatives to overcome them. The structural problem stems in part from the inefficient system in FTA policy making and its implementation. Most importantly, there is a lack of ex-ante consensus building among stake-holders. As an alternative to the current FTA policy, we suggest two things. First, we argue that an FTA negotiation strategy should correspond to Korea's overall industrial development strategy. Second, the National Assembly should play an important part for enforce of trade policies as a tool for advancing a comprehensive strategic measures.

To investigate how the online searching was taught in the departments of Library and Information Science, a survey was done to the professors teaching information retrieval course. Questionnaires were mailed to 32 professors and 26 returned. Information retrieval course, one of the central course attended by almost all of the students, covers online searching in depth. Lecture, hard-on practice, and homework were three favored methods of teaching. Among the 22 topics to be covered in online teaching, respondents showed substantially higher consensus except for sections of information technology and service management. However, respondents showed big differences in hours of hand-on practice and the systems used. Free databases through Internet used dominantly. The chronic problem of terminal and communication is solved by using campus-wide facilities. But the problem of teaching assistance is serious. Based on the results, recommendations to improve online searching education are provided.

Various organizational factors effect successful implementation of IT enabled business transformation. Among them, the most critical success factor is deemed to overcoming change management problem. Lots of studies have been made on implementation methodologies and business process formalizations to encourage organizational members to accept new business process changes. However, the logic of process redesign still depends on qualitative problem solving techniques mostly depending on basically human intuition such as brainstorming, cause-and-effect analysis, and so on. In this paper, we develop algorithmic procedure applicable to designing various business process changes such as process automation, business process resequencing, and more radical process integration. The framework is employed from dynamic programming approach in the literature, which is based on the decision making paradigm of organizations to abstract business processes as quantitative decision models. As such, our research can fill the gap of limited development of theory based analytic methodologies for business process design, by providing objective rationale to reach the consensus among the organizational members including senior management.

In this paper, we propose an election protocol based on mobile ad-hoc network. In distributed systems, a group of computer should continue to do cooperation in order to finish some jobs. In such a system, an election protocol is especially practical and important elements to provide processes in a group with a consistent common knowledge about the membership of the group. Whenever a membership change occurs, processes should agree on which of them should do to accomplish an unfinished job or begins a new job. The problem of electing a leader is very same with the agreeing common predicate in a distributed system such as the consensus problem. Based on the termination detection protocol that is traditional one in asynchronous distributed systems, we present the new election protocol in distributed systems that are based on MANET, i.e. mobile ad hoc network.

Recently, the government tends to address the health policy as an economic logic. However, health policy must be priority to national health right than economic logic. Thus, in this paper analyzes the problems of telemedicine for telemedicine that are at issue in South Korea, based on this, and presents reasonable health policy directions for telemedicine. To amend the law and legislation the health policy and law, analyze the rationality, feasibility of law and sufficient review should be implemented. Comparing to the foreign which introduced telemedicine earlier, discussion on telemedicine in South Korea remains a long way to go and it is now beginning step. Therefore, it should not forget that the health policy of the government with crass insensitivity can bring great disaster. Above all, to the health care, the sufficient review and social consensus which can reduce the side-effects are priority.

The Multisensor Fusion Problem (MFP) deals with the methodologies involved in effectively combining together homogeneous or non-homegeneous information obtained from multiple redundant or disparate sensors in order to perform a task more accurately, efficiently, and reliably. The inherent uncertainties in the sensory information are represented using Fuzzy Numbers, -numbers, and the Uncertainty-Reductive Fusion Technique (URFT) is introduced to combine the multiple sensory information into one consensus -number. The MFP is formulated from the Information Theory perspective where sensors are viewed as information sources with a fixed output alphabet and systems are modeled as a network of information processing and processing and propagating channels. The performance of the URFT is compared with other fusion techniques in solving the 3-Sensor Problem.

Throughout the modernization which was dominated by development theory in Korea, land use planning for housing tended to spoil the environment. Numerous studies, however, pointed out the problem of this development-led planning and there was a broader consensus that the past planning was part of the environmental problem of inner city. These observations changed the development-led planning into the environmental friendly development planning. In particular, Seoul Metropolitan Government held the international planning competition to develop 'Sangam' as an environment friendly residential area. With this plan 'Sangam' would be the sustainable residential area with the harmony of nature, human and technology. Furthermore it would be the outset of the long-term plan to develop 'Seoul' as a 'gate-city, an 'information-city' and an 'eco-city'. To do this, it needs especially the planners' and the constructors' constant concerns and efforts as well as the citizen's participation.

This paper proposes a new method to process panoramic image stitching using SURF(Speeded Up Robust Features). Panoramic image stitching is considered a problem of the correspondence matching. In computer vision, it is difficult to find corresponding points in variable environment where a scale, rotation, view point and illumination are changed. However, SURF algorithm have been widely used to solve the problem of the correspondence matching because it is faster than SIFT(Scale Invariant Feature Transform). In this work, we also describe an efficient approach to decreasing computation time through the homography estimation using RANSAC(random sample consensus). RANSAC is a robust estimation procedure that uses a minimal set of randomly sampled correspondences to estimate image transformation parameters. Experimental results show that our method is robust to rotation, zoom, Gaussian noise and illumination change of the input images and computation time is greatly reduced.

In 1959, Satomura used spectral Doppler ultrasound to express the velocity of red blood cells according to time change, and Kato defined a zero-base line that could tell the direction of blood flow, making it possible to know the direction of blood flow. This became the basis for the widely used classifications of Triphasic, Biphasic, and Monophasic. However, the above classification has limitations that confuse users with the meaning and timing of use in a clinical environment. As a result, the American Society for Vascular Medicine (SVM) and the Society for Vascular Ultrasound (SVU) A consensus document on Doppler waveform analysis was declared by the joint committee. This study tried to review this consensus and to suggest nomenclature and modifiers that can be used in the domestic vascular ultrasound clinical field. The joint committee formed by SVM and SVU recommended that the use of the triphasic waveform and the biphasic waveform be used as a multiphasic waveform rather than being used due to the ambiguity of interpretation. In addition, it was agreed to name the hybrid-type waveform, which is a monophasic and high-resistance waveform, which has always been a problem of interpretation in a clinical environment, as an intermediate resistive waveform. In addition, in order to increase the communication efficiency between the interpreter and the sonographer, waveform analysis was classified into a main descriptor and a modifier, and it was recommended to use a single nomenclature by unifying various synonyms. It is expected that this literature review will provide accurate arterial spectral Doppler waveform interpretation and an agreed-upon nomenclature to radiologists performing vascular ultrasound examination in clinical practice, and will be utilized as basic data that can contribute to the improvement of public health.
