내진성능평가 시스템은 구조시스템의 합리적인 분류, 적절한 평가 기준, 그리고 종합적인 평가방법을 포함하여야한다. 외국의 현행 내진성능 평가방법은 데이터의 수집과 주요 평가 항목을 위한 약산식 그리고 평가 점수를 이용하여 전문가의 판단에 근거한 평가 방법을 제시하고 있다. 본 연구는 국내 건축구조물에 예비 내진평가 방법에 중점을 두고 퍼지추론 시스템에 근거한 내진평가방법의 전형을 개발한다. 평가항목의 위계는 건무의 수직, 수평방향을 불규칙성, 비대칭성, 여용성, 그리고 건물 연한을 포함한 전체적인 특성과 부재 단계에서의 상세한 평가 항목으로 구성한다. 퍼지추론방법에 대한 기존의 연구결과를 근허가혀 이용한 내진성능 평가방법에 적절히 적용하기 위하여 4가지 주요 모듈을 설정한다. (1) 퍼지 입력 (2) 퍼지에 근거한 규칙기반 (3) 퍼지추론, 그리고 (4) 퍼지출력으로 구성된다. 더욱이 개별적인 성능 수준에 종합적인 평가지수를 끌어내기 위하여 퍼지추론방법을 적용하였다.

As the condition evaluation of the active rules is performed whenever an event occurs, the performance of the system is influenced greatly depending on the conditions Processing method. Therefore, a study on evaluating the conditions of active rules becomes a very important element for enhancing the performance of active database. and the processing time of the calculation generated from the conditions must be minimized in order to improve the Performance. In this paper, the tree processing system which can effectively Process the join and selection operations is proposed. The experimental results show that tree processing system has the lower evaluation cost for the conditions processing of the active rules than the existing methods.

The evaluation method for the failure frequency of reactor vessel under pressurized thermal shock(PTS) is developed using probabilistic fracture mechanics. The probabilistic reactor integrity evaluation code, named R-PIE code, is developed. The validity and uncertainty of the R-PIE code is investigated. The reactor failure frequencies under PTS for Kori-1 nuclear power plant and other type of domestic nuclear power plants are evaluated. The reference PTS temperature for domestic nuclear power plants is obtained for the rule making against PTS failure.

In this paper, we propose system that apply VIBL method to add speech recognition to LIBL method based on human s studying method to use natural language to steering system of ship, MERCS and winch appliances and use VIBL method to alternate process that linguistic instruction such as officer s steering instruction is achieved via ableman and control steering gear, MERCS and winch appliances. By specific method of study, ableman s suitable steering manufacturing model embodies intelligent steering gear controlling system that embody and language direction base studying method to present proper meaning element and evaluation rule to steering system of ship apply and respond more efficiently on voice instruction of commander using fuzzy inference rule. Also we embody system that recognize voice direction of commander and control MERCS and winch appliances. We embodied steering manufacturing model based on ableman s experience and presented rudder angle for intelligent steering system, compass bearing arrival time, evaluation rule to propose meaning element of stationary state and correct steerman manufacturing model rule using technique to recognize voice instruction of commander and change to text and fuzzy inference. Also we apply VIBL method to speech recognition ship control simulator and confirmed the effectiveness.

Objectives : The purpose of this study was to survey the opinion and attitude of hospital managers toward the hospital evaluation program. Method : Managers of 157 hospitals which had participated in the hospital evaluation program were requested to respond to structured self-administered questionnaire. The questionnaire was composed with five categories: the preparation for the hospital evaluation program, the expertise levels of surveyors, the process and contents of the hospital evaluation program, the applying strategies for the result of the hospital evaluation to manager's work at their hospitals, and the main points to improve the hospital evaluation program. Result : 135 out of the 157 subjects completed the questionnaire, and the overall response rate was 86%. The hospital managers answered that they didn't have enough information such as the scoring rule of the standards, the process of the evaluation, and how to ask and get an answer to prepare the hospital evaluation. Furthermore, they estimated that the surveyors weren't specialized enough and didn't give a chance of checking over the result of the evaluation. In addition, they experienced that the result and feedback of the evaluation weren't enough information to be used as a guideline to improve in hospital management. Managers of the hospitals responded that the standards and method of survey in the hospital evaluation system should be reformed. Conclusion : Most of the responded managers seemed to have negative opinion on the hospital evaluation system, even though they were pushed up for interest in quality. Further studies and extensive evaluation of the hospital evaluation program are needed to bring up various information such as receptiveness and effectiveness.

A unit-load automated guided vehicle system is considered in which a single vehicle is operated on a unidirectional path in a closed loop. The vehicle serves a manufacturing cell moving pallets from one station to another based on the "First-Encountered-First-Serve" dispatching rule. An approximation method is developed to compute the mean waiting time of an arbitrary pallet at each station. Extensive numerical experiments, performed for various problems, yield fairly good results in most of the cases compared with those obtained by simulation method.

In 1911 Schur[6] derived degree and character formulas for projective representations of the symmetric groups remarkably similar to the corresponding formulas for ordinary representations. Morris[3] derived a recurrence for evaluation of spin characters and Stembridge[8] gave a combinatorial reformulation for Morris' recurrence. In this paper we give combinatorial interpretations for the orthogonality relations of spin characters based on Stembridge's combinatorial reformulation for Morris' rule.

This study proposes JPT(Job-Pair Tardiness) that choose operation to be expected to generate better schedule consequence in comparing schedulable operation sets in pair to minimize total tardiness evaluation function in performing scheduling. In result of comparison with existing assignment rules. JPT generates better solution than most other rules in all kinds of problems. So it is anticipated that this is used for initial solution of heuristic and is used for finding more improved solution.

In this paper, a rule based Mamdani type fuzzy logic model for prediction of slippage at maximum tensile strength and slippage at rupture of structural lightweight concretes were discussed. In the model steel rebar diameters and development lengths were used as inputs. The FL model and experimental results, the coefficient of determination R2, the Root Mean Square Error were used as evaluation criteria for comparison. It was concluded that FL was practical method for predicting slippage at maximum tensile strength and slippage at rupture of structural lightweight concretes.
