MR imaging에서 RF pulse에 의한 Spin들의 이동과 dephase, rephase 되는 모양을 Spin visualization을 사용하면 직관적으로 이해할 수 있다. 다양한 각도의 RF pulse 가 여러 번 가해지면, spin echo 외에도 stimulated echo, "eight-ball" echo 등이 나타나기 때문에 직관적으로 echo들을 이해하기가 어려워진다. Spin에 RF pulse가 가해졌을 때, 기존의 2차원의 Profile로 spin들의 상태를 보는 것보다 3차원 공간상에서 spin들의 상태를 살펴봄으로써, 좀 더 쉽게 MR 신호를 이해할 수 있다. 특히 고자장에서 SAR 문제 때문에 낮은 각도의 RF pulse 를 사용하여 영상을 해야 하기 때문에 spin visualization은 새로운 영상 방법을 이해하거나 디자인하는데 중요하다.

Currently, unlike domestic market It is trend that world construction market scale is increasing continuously but Experts who need in International Construction Market are insufficient absolutely. Despite the amount of orders received continuously increased, Experts who needed for overseas construction market are lacking. And we need to examine that Experts who needed for overseas construction market an supplied to the country. It is time to make decision how can we supply them to the country. Consequently, this project will study Educational programs of the past for Training International Construction Experts, provide the solutions breeding International Construction Experts.

The evaluation of the quality of residential environment may be different according to the experts' characteristics. This study aimed at estimating the relative weights of the constituents of a residential environment by AHP(Analytic Hierarchy Process) through experts' evaluation. The respondent group was composed of 72 experts in the fields of architectural design, housing design, urban design, and urban planning. The findings are as follows(:) 1) the relative weights of residential constituents were different between detailed fields ; 2) the relative weights of residential constituents were not different according to institute in which experts are engaged ; and 3) for the practical application of estimation results of the relative weights, the relation between residential performance constituents and physical design elements should be considered in future.

One of the most important problems on rule induction methods is that they cannot extract rules, which plausibly represent experts decision processes. On one hand, rule induction methods induce probabilistic rules, the description length of which is too short, compared with the experts rules. On the other hand, construction of Bayesian networks generates too lengthy rules. In this paper, the characteristics of experts rules are closely examined and a new approach to extract plausible rules is introduced, which consists of the following three procedures. First, the characterization of decision attributes (given classes) is extracted from databases and the classes are classified into several groups with respect to the characterization. Then, two kinds of sub-rules, characterization rules for each group and discrimination rules for each class in the group are induced. Finally, those two parts are integrated into one rule for each decision attribute. The proposed method was evaluated on a medical database, the experimental results of which show that induced rules correctly represent experts decision processes.

This study beings from solving problems of permanent rental housing with environmentally-friendly planning factors to raise quality of life. Environmentally-friendly planning factors of permanent rental housing are derived from the study of references and green building certification systems of other countries. Surveys of inhabitants and experts give weights on these factors. Inhabitants do are focussed natural ventilation, life cycle cost, operation and maintenance cost. This reflects their interest in indoor amenity and a burden on the cost. Experts put more weights on pedestrian spaces considering the old and feeble persons and block planning. Besides, T-test pointed out that there are meaningful differences in land use between inhabitants and experts. Though inhabitants' opinion has priority because they are real user, experts' opinion which has the variety and the view in the long term should be reflected.

A short shot is a molded part that is incomplete because insufficient material was injected into the mold. Remedial actions to control the process conditions can be taken by the injection molding experts based on their knowledge and experience. However, it is very difficult for the non-experts to avoid short shot by finding the proper process conditions such as mold temperature, melt temperature and filling time. In this paper, an intelligent generator of the optimal process conditions based upon fuzzy logic algorithm is proposed so that trial and error can be minimized and the non-experts as well as the experts can also find the optimal process conditions.

In debureing process. Human experts who have long experenc in performing deburring tasks can manipulate tools efficiently and adapt the tool motions according to the state of the process based on their skills. However, human experts have difficulties in describing linguistically their control schemes and strategies because teey don't aware the detailed process in interpreting wensory information and adapting tool motion. Therefore, it is important to develop a mean of understanding the skills and acquiring the control schemes so that the robot can perform the same skillful motion as the human experts. In this paper, an expert's skill model is developed so that it can be transferred effectively from the expertt to the robot. Skills are represented by a mapping which is generated by using a neural network. Expert's skill shows that the robot is able to associate a correct control strategy with process characteristics which is acquired from a vision image in a similar manner to a human expert's

This study tried to find out alternatives adjusting basic fare using customer survey. But it merely verified that train fare decision is made by government's role and market status. Also, it has a limitation deciding resonable fare of KTX that average cost and marginal cost calculation is impossible because Korean National Railroad does not follow 'Activity Based Costing'. It is rational fare decision that performing survey to railroad experts and general customers, and compare two results. Summarizing results of this study, 1. The hypothesis 'Experts' perceived fare level of KTX is higher than that of general customer. 'is carried. It suggests that following experts' opinion with general customer's is very rational method to decide fare level. 2. The hypothesis 'Experts expect lower level of fare discount rate than general customer.' is carried. 3. It is hard to decide priority among many kinds of discount for difference of two group's preference. However, following recent research project is maximized by discounting fare 30$\%$ on 40$\%$ of total passenger and expand number of discount kinds step by step are desirable.

Development of complex discrete event simulators requires cooperation between domain experts and modeling experts who involve the development. With the cooperation the domain experts derive user requirement and modeling experts transform the requirement to a simulation model. This paper proposes a method for consistency verification of simulation model in DEVS formalism against the user requirement in UML diagrams. It also presents an automated tool, called VeriDEVS, which implements the proposed method. Inputs of VeriDEVS are three UML diagrams, namely use case, class and sequence diagrams, and DEVS Graph, all in Visio; outputs of a verification result is represented in PowerPoint files.
