This study suggests a new methodology for the fault diagnosis based on the signed digraph in developing the fault diagnosis system of a boiler plant. The suggested methodology uses the new model, fault-effect tree. The SDG has the advantage, which is simple and graphical to represent the causal relationship between process variables, and therefore is easy to understand. However, it cannot handle the broken path cases arisen from data uncertainty as it assumes consistent path. The FET is based on the SDG to utilize the advantages of the SDG, and also covers the above problem. The proposed FET model is constructed by clustering of measured variables, decomposing knowledge base and searching the fault propagation path from the possible faults. The search is performed automatically. The fault diagnosis system for a boiler plant, ENDS was constructed using the expert system shell G2 and the advantages of the presented method were confirmed through case studies.

Fuzzy L.P. with Multi-criteria function is adopted in this VAR planning algorithm to accomplish the optimization of comflicting objectives, such as the amount of the VAR installed and power system loss, while keeping the bus voltage profile within an admissible range. Fuzzy L.P. with Multi-criteria function, a powerful tool dealing with the fuzziness of satisfaction levels of the constraints and the goal of objective functions, enables us to search for the solutions which may contribute in VAR planning. This advantage is not provided by traditional standardized L.P. The effectiveness of the proposed algorithm has been verified by the test on the IEEE-30 bus system.

The purposes of this study are to search for counselor's change process and factors in Theraplay, and to explore how they are changed into experts. This study used a method of qualitative study to reveal a concrete context of child counseling. The results are as follows. Therapist or counselor subjects realized that therapy(counseling) was not focusing on activities, but on meanings. In the beginning, therapist subjects acted according to the situation rather than according to the child's reactions and their own strategy. It was expressed into long and boring explanations, trials to flatter a child. Therapist subjects were often depressed because of their incompetence, they even did overpraise for the undistinguished behavior of children, but gradually they have changed into expert therapists through ceaseless interaction with Theraplay community, reflection, trial and practice.

This paper presents a new algorithm to restore the de-energized loads in electric power distribution systems for restoration by utilizing object-based structure and heuristic rules without branch and feeder overloading. In order to cope with a complex network configuration and frequent breaker switching operations in distribution systems, the component of power system is described as objects and the information of system configuration is constructed by connecting objects each other. Such a strategy is developed mainly based on the object search algorithm to increase computation efficiency. As a result, the proposed system has been implemented to efficiently deal with large distribution systems by reducing computational burden remarkably compared with the conventional methods.

This paper proposes IIKBAG(Intelligent Interlocking Knowledge Base Generator) which can build automatically the interlocking knowledge base utilized as the real-time interlocking strategy of the electronic interlocking system in order to enhance it's reliability and expansion. The IIKBAG consists of the inference engine and the knowledge base. The former has an auto-learning function which searches all the train routes for the given station model based on heuristic search technique while dynamically searching the model, and then generates automatically the interlocking patterns obtained from the interlocking relations of signal facilities on the routes. The latter is designed as the structure which the real-time expert system embedded on IS(Interlocking System) can use directly in order to enhances the reliability and accuracy. The IIKBAG is implemented in C computer language for the purpose of the build and interface of the station structure database. And, a typical station model is simulated to prove the validity of the proposed IIKBAG.

Purpose: The purpose of this literature review was to describe the roles of advanced practice nurses related to advance directives. Methods: A comprehensive literature review was conducted utilizing Pubmed, Ovid, and CINAHL. The key words for search were 'advance directives', 'living wills', 'durable power of attorney', 'advanced practice nursing', 'advanced practice nurse', 'nurse practitioner', and 'nurse specialist'. Research articles published between January 1990 and September 2010 and written in English were included. Review papers and expert's opinion were excluded. Results: Five articles were yielded and analyzed. Among them, two focused on the advanced practice nurses' role during the process of advance directives. The other three presented the outcomes depending on the type of nurses' involvement in each health care delivery system. Conclusion: Recently, Korea established advance directives and expanded to diverse sites. Advanced practice nurses' role in the advance directive decision-making process should be examined and developed in research and practice.

In the medical web forum, people share medical experience and information as patients and patents' families. Some people search medical information written in non-expert language and some people offer words of comport to who are suffering from diseases. Medical web forums play a role of the informative support and the emotional support. We propose the automatic classification model of articles in the medical web forum into the information support and emotional support. We extract text features of articles in web forum using text mining techniques from the perspective of linguistics and then perform supervised learning to classify texts into the information support and the emotional support types. We adopt the Support Vector Machine (SVM), Naive-Bayesian, decision tree for automatic classification. We apply the proposed model to the HealthBoards forum, which is also one of the largest and most dynamic medical web forum.

This study analyze the certified management bodies for rural convergence industry promotion in Jeonnam province. The main results are as follows. Firstly, both certified management bodies and committee members are positive about the prospects of the 6^th industry, and they also agree on the need for 6^th Industrial accreditation system. Secondly, The 6^th industry affects "creation of value added" and "linked to regional agriculture." In other words, we can see that the 6^th industry can contribute to creating new values and linking regional agriculture. Finally, in order to foster certified management bodies for the 6^th industry, the management bodies put joint promotion, marketing and sales support on a priority basis, and was interested in supporting commercialization, such as on-site coaching, while the expert committee put priority on fostering the search for profit models, placing importance on supporting commercialization such as customized coaching.

All of the people or objects which are contacted during the activity of guard are added to range of objects. guard has to notice decision, question proposal, observation, accomplish to be happened them at the same time recognizing the steps as soon as possible. Before a lot of information of client are shown, guard expert has to search observation of materialization, extension of reservation, notification of business and causes of danger through personal interviews. Rapid communication system has to be assumed and effective caution, protection and shelter and following prevention are cooperated as well as has to care about safe of guard object by a protective wall. And also has to get out of the ground, keep the large shape when moves, prevent the trials of attack from the assassinators after takeing control over weapons.
