발견된 Web Usage 패턴들은 분석하는 전문가에게는 불필요하고 흥미롭지 못해 의사결정에 도움이 못되는 경우가 많다. 따라서 발견된 패턴에 대한 도메인 전문가의 사전 Belief에 기반한 패턴 검증 과정이 필요하다. 발견된 패턴의 유용성 여부는 패턴의 Unexpectedness를 측정함으로써 결정할 수 있다. 본 논문에서는 패턴의 Unexpectedness를 전문가의 Belief에 기반하여 검증하기 위한 새로운 방법론 제안한다. 발견된 패턴과 전문가 Belief를 매칭 알고리즘을 이용하여 패턴을 4가지(완전일치, 조건부 일치, 결과부 일치, 완전 불일치)로 분류하는 1차 검증과 1차 검증 결과의 4가지 분류데이터를 통계적 추론 방법인 Dempster-chafer에 적용한 2차 검증으로 나뉜다. 1차 검증 과정은 패턴의 분류 용이성을 부여하나 패턴의 Unexpectedness에 대한 신뢰성을 제공하지 못한다. 이 문제점을 2차 검증 과정을 통해 해결한다.

Rule-based knowledge representHtion is, the most popular technique for ,storage and manipulation of domain knowledge in expert system. By the way, the amount of knowledge increases more and more in this representatiun technique, it, relationship becomes complex, and even its contents can be modified. This is the reason why rule-based knowledge representation technique requires a verification ,system which can maintain consistency and completeness of knowledge base. This paper is to propose a verification system for consistency and completeness of knowledge base to promote the efficiency and reliability of expert system. After verifying the potential errors both in structure and in semantics whenever a new rule is added, this system renders knowledge base consistent and complete by correcting them automatically or by making expert correct them if it fails.

Verbal Protocol Analysis(이하 VPA)와 Repertory Grid(이하 RG)를 활용하여 구매 전문가의 지식을 온톨로지로 구축하여 활용할 수 있는 방법론 제시하였다. VPA를 활용하여 전문가의 생생한 지식을 실제와 거의 유사하게 구어체의 문서로 표현하고, 다시 RG를 이용하여 온톨로지로 표현하는 절차와 세부 방안을 구축하였다. 본 연구의 방법을 활용하여 지식 온톨로지를 구축하면 전문가의 암묵적 지식을 실제와 가깝게 상호운영이 가능한 구조화된 지식으로 표현 할 수 있고 나아가 표현된 지식의 다양한 활용이 가능해 진다. 이와 같이 전문가의 암묵지를 실제와 가깝게 표현하고 이를 재활용 가능한 형태로 구조화할 수 있다는 것은 지식의 표현, 축적 그리고 활용을 위해서 매우 중요한 의미가 있다고 할 수 있다. 한편, 본 연구의 방식대로 표현된 구매 전문가의 지식 온톨로지에 대해 현장 전문가가 이를 평가하여 본 연구에서 제안하는 내용의 의미적 가치와 우수성을 검증하였다.

The purpose of this study was to develop the instruments which can measure motivation as a component of Visual Artistic Giftedness with in elementary school period. This study prescribed the variable factors of measurement after abstract and classify the characteristics of Visual Artistic Giftedness through literature studies. And it produced instruments those are finally composed of 27 items through the preliminary test. They were evaluated in terms of content validity, construct validity, and reliability by implementing them to 679 elementary school children from the first to sixth grades. Statistical analyses were carried out to verify the validities and reliability. Content validity was found to be satisfactory by experts' evaluation on the test items. Construct validity was also found to be satisfactory through factor analyses which showed the four factors which the identification instruments were intended to measure such as, interest/ attitude/ taste, endurance/ concentration, curiosity/ imagination! sensitiveness, aesthetic. Concurrent validity was also found to be satisfactory with high coeffients of Barron- Welsh which were calculated as .76 in motivation. In conclusion, the instruments about motivation of Visual Artistic Giftedness during elementary school period developed by this study are highly reliable on its reliability and validity.

In this article, an Expert System for MIDship section design(ESMID) is developed based on a general-purpose expert system shell. The system focuses on the integration of knowledge-based system and design resources such as an engineering database, graphical user interface, and engineering application program for the calculation of section modulus and longitudinal strength of ship structure. The validation of the ESMID system was examined and verified by applying the system to the 64K bulk carrier. The developed expert system can help a novice engineer in designing the midship section of ship.

As Korea is now an aging society, the demand and necessity of assistive products for senior citizens are increasing. On the other hand, their satisfaction with the assistive-product payment service is pretty low, so that the necessity of assistive-product specialists is newly rising. Therefore, it is important to establish a frame of assistive product specialist and clarify the duties. This study aimed to define and analyze the job of assistive-product specialists. This study was carried out from June 1, 2015 to February 10, 2016. After the literature consideration and analysis of the current status, a job analysis(plan) of assistive product specialists was drawn after the job of assistive product specialists was defined, and the duties, tasks, and task elements were analyzed by experts through an advisory conference. A Delphi method was conducted with five professional panels to verify the validity. For the job contents of assistive product specialists, 5 duties, 12 tasks, and 23 task elements were identified. The significance of this study was to establish the system and standard for assistive device specialists defining and analyzing the job of assistive product specialist. Through this study, it would be possible to secure the professionalism of an assistive-product specialist and qualitative improvement of an assistive-product payment service.

본 연구에서는 실무 및 학계에 종사하는 45명의 전문가 집단을 대상으로 쌍별비교(pairwise comparision)에 의한 설문조사에서 얻어진 전문가들의 의견을 AHP 분석을 통하여 종합하는 과정을 거쳐 부도예측모형을 설계하여 검증한 뒤, LOGIT모형과 비교하였다. 본 연구에 의하면 부도예측모형에서 정량적인 정보보다 정성적인 정보가 더 중요한 역할을 한다는 D.Bunn-G.Wright(1991)의 연구와 일치하는 결과를 얻을 수 있었다. 본 연구에서 발견된 분석결과를 요약하면 다음과 같다. 첫째로 LOGIT 모형과 AHP 모형에서 모두 정량적인 정보만을 고려하는 경우보다 정성적인 정보를 함께 고려한 모형에서 부도예측율이 더 높은 것으로 나타나고 있어 부도가능성을 예측하는데 있어 정성적인 정보가 중요한 역할을 한다는 결론을 얻었다. 둘째로 AHP를 이용한 부도예측 모형을 설계할 때 각 속성에 대한 전문가(45명)들의 의견을 종합하는 방법으로 산술평균과 기하평균을 이용한 검증결과에 의하면 기하평균방법을 통하여 전문가들의 의견을 종합하는 것이 보다 합리적이라는 실증적 증거를 얻을 수 있었다. 셋째로 Akaike의 기준값을 분석한 결과에 의하면 LOGIT 모형은 정량적인 정보와 정성적인 정보를 모두 이용한 모형이 가장 우수한 것으로 판명되었고, 모형의 부도예측력도 가장 높은 것으로 밝혀졌다. AHP 모형은 정성적인 정보만을 이용한 모형에서 가장 높은 부도예측을을 나타내었으며, 기하평균을 이용한 AHP 모형은 LOGIT 모형보다 항상 높은 부도예측율을 보여주었다.
