연삭숫돌 선택은 공작물제거량, 숫돌의 소모량, 표면정도 및 공작물의 물리적,화학적 특성을 고려하여 설정하는 것을 기본으로 한다. 연삭가공은 구성인자의 상호관계가 복잡하여 이중에서 어느한 요소만을 고려하여 설정하기 어렵고 정량적 기준 또한 정해져있지 않아 현실적으로는 숙련자의 정성적이고 경험적 지식에 따른 주관적 척도에 의존하는 것이 대부분이다. 또한, 연삭숫돌은 작업조건중에서 대량생산을 제외하고는 되도록이면 현장에 구비되어 있는 작업가능한 연삭숫돌 중에서 선택하는 것이 바람직하다. 따라서 본시스템에서는 이와같은 점을 고려하여 최적 연삭숫돌선택을 퍼지이론에 기초한 현장 숙련자의 지식을 활용하므로써 연삭숫돌선택의 효율성을 도모하는 동시에 현장에 연삭숫돌이 구비되지 않은 경우도 고려하여 연삭숫돌설정에 우선순위를 제시하므로써 작업자에 연삭숫돌선택의 유연성을 부여하였다. 또한, 실용성있는 전문가시스템의 구축을 위해 정성적이고 경험적인 지식의 활용을 위한 지식표현으로 설문조사에서 얻은 테이타를 x$^{2}$-분포에 따른 추정신뢰구간을 구해, 이를 토대로한 비대칭 삼각퍼지함수의 결정법을 제시하고, 이를 이용해서 구축한 시스템의 실행결과의 타당성을 비교하고자 한다.

In Korea, the number of recalled products is steadily increasing annually, but the recall participation rate of consumers is very low. This study looked at recall competency as a necessary factor for active recall participation by consumers. And identify the components of the recall competency and identify the recall competence factors that influence recall experience. To this end, we examined the recall experience and recall capacity of 1,626 adult consumers in Korea. As a result, five factors of recall participation will, recall related skill, recall policy recognition, subjective knowledge and objective knowledge were derived. As a result of comparing recall competencies among recall experience and non-recall experience, there were statistically significant differences in all competency factors. Recall related skill and subjective knowledge competency were significant factors for recall experience. In order to improve the effectiveness of the recall system, it is important to improve the recall information and increase access to information retrieval in order to increase the recall participation rate by strengthening the recall capacity of consumers.

I studied on the relations of constructivism and school library assisted instruction in this paper. Constructivism is the most important goal of the modern schooling. In constructivism they insist that knowledge is constructed by the learner individually and subjectively. So in constructivism they focus their attention on setting authentic environment of learning for each individual learner. Constructivism was developed into the learner-centered instruction in schooling nowadays. In constructivism the following instructions are very important for achievement its' goal ; problem based learning, project based learning, discussion based learning etc. These instructions are supported commonly by resource based learning. Educational resources are managed in school library totally. School library assisted instruction is the most effective one for resource based learning. And information literacy instruction by teacher librarian relates closely meta cognitive learning of reflections in constructivism. School library assisted instruction is the essential element for the practice of constructivism in schooling.

Due to differences in singing styles and voice production between classical and popular music singers, their knowledge and practice regarding vocal hygiene may differ. This study compared the knowledge and practice of vocal hygiene among 121 university undergraduate students (58 classical and 63 popular music vocal majors). Additionally, the correlation between the level of knowledge and practice of vocal hygiene and the subjective voice evaluation was examined. The results revealed that both knowledge and practice of vocal hygiene were significantly higher in classical than popular music vocal majors, and that vocal hygiene practice was significantly higher than knowledge in the entire group. In addition, there was a weak positive correlation between knowledge and practice of vocal hygiene; and a weak negative correlation between vocal hygiene practice and subjective voice evaluation. This study suggests that popular music vocal majors have relatively lower levels of knowledge and practice in vocal hygiene than classical music vocal majors. It also highlights the need to provide tailored vocal hygiene education programs for both classical and popular music vocal majors, as they show low levels of knowledge and practice in certain aspects of vocal hygiene.

우리나라 정부는 공공연구기관에서 개발된 기술을 민간부문에서 사용을 극대화하여 기업 및 국가경쟁력을 제고하기 위하여 기술이전과 기술평가 및 기술정보유통 등의 기반을 확충하여 산업전반의 기술경쟁력을 강화하고 있다(기술이전촉진법 제정(2000. 1. 28). 이와 같은 변화는 국가경쟁력의 무게중심이 산업기반경제에서 지식기반경제로의 이동을 나타내는 것이며, 미국을 비롯한 선진 국가들의 움직임은 우리나라보다 10년 이상 앞선 상태이다. 지식기반경제에서는 특허의 전략적 활용이 가장 중요하게 여겨지고 있으며 각 연구기관 및 기업은 특허의 포트폴리오에 총력을 기울이고 있다. 그러나 특허의 사업화 가능성을 판단하여 우수 특허군을 분류하거나 특허의 등록유지에 관한 결정을 내릴 때 현재 특허실사 맵, Risk-Return chart, 전문가 심의 방법을 범용하고 있으나 이와 같은 세 가지 방법은 평가자 개인의 주관적 입장이 강하게 작용하고 있어 문제점으로 지적된다. 본 고에서는 기존의 특허실사 방법론의 맹점인 평가의 주관성을 배제하기 위하여 객관적이고 표준화된 정보인 특허를 사용하여 고안된 두 가지 특허지수(CPP, TCT)를 사용하여 객관적인 특허실사 방법을 제안하고 실증분석을 통하여 사용 가능성을 고찰해 보았다.

Found pesticide-contaminated eggs in 2017, the situation became a hot issue in many countries in the world as well as Korea. In the context of the pesticide-contaminated egg, this study explored that preventive behavioral intention would be predicted by perceived susceptibility and severity from health belief model, trust in the government and evaluation of information from the government, and subjective knowledge. We found that preventive behavioral intention was explained by perceived severity (${\beta}=.262$, t=3.531, p<0.001), trust in the government (${\beta}=.25$, t=3.281, p<0.001), and evaluation of the information from the government (${\beta}=.226$, t=2.936, p<0.01) through stepwise multiple linear regression analysis. The findings imply the government would administer policy in terms of credibility, accuracy, and consistency for decreasing the public's sense of unease and panic when a similar incident occurs.
