본 연구는 환자가 느끼는 자신의 주관적 구강보건영향지수(OHIP-14; Oral Health Impact Profile-14)가 구강보건이 삶의 질(QOL; Quality of Life)에 어떤 영향을 미치는지 알아보고 구강질환 예방과 구강보건 향상을 위한 프로그램을 개발하는데 필요한 기초 자료를 제공하여 지역사회주민의 건강과 삶의 질을 증진하고자 한다. 주관적 구강건강상태에 따른 OHIP를 분석한 결과 자가 인식 구강건강상태는 전 영역에서 유의한 차이가 있었고, 총 점수가 건강한 편이 4.33으로 유의하게 높았다. 주관적 구강건강상태에 따른 QOL을 분석한 결과 자가 인식 구강건강상태에서는 사회적 영역을 제외한 전 영역에서 유의한 차이가 있었으며, 총 점수는 건강한 편이 3.39로 가장 높았다.

SOM 알고리즘에서 가중치 조정은 입력 벡터와 승자 노드의 대표 벡터간의 차이만큼 조정되고 승노드의 대표벡터에 입력벡터의 정보를 반영하게 된다. 여기서 그 정보를 반영할 때 입력벡터와 승자노드의 대표 벡터간에 차이가 크면 승자 노드의 대표 벡터에 입력벡터를 기억시키기 위해 입력 벡터의 정보를 더 많이 반영해야 한다. 이러한 문제점을 개선하기 위해 본 논문에서는 승자 노드의 대표벡터와 입력벡터간의 출력오류를 0과1사이의 정규화된 값으로 출력오류를 계산하여 학습률을 조정하고 승자 노드의 저 활용 문제를 개선하기 위해 학습 중에 각 승자 노드의 대표 벡터들이 수정되고 선택되어지는 횟수가 가능한 동등해지도록 각 노드의 승자 빈도수를 가중치 조정에 반영하는 개선된 SOM 알고리즘을 제안하였다. 제안된 방법의 인식 성능을 평가하기 위해 주민등록증에서 추출한 숫자 패턴 50개를 대상으로 실험한 결과, 제안된 방법의 인식 성능이 기존의 SOM 알고리즘보다 개선된 것을 확인하였다.

In this paper, we propose an efficient method for recognizing pupils and lip in a human face. Pupils are detected by a cost function, which uses features based on the eye's shape and a relation between pupil and eyebrow. The inner boundary of lip is detected by weighted vectors based on lip's shape and on the difference of gray level between lip and face skin. These vectors extract four feature points of lip : the top of the upper lip, the bottom of the lower lip, and the two corners. The experiments have been performed for many images and show very encouraging result.

The purpose of this study is to investigate the effects of lessons adopting portfolio assessment regarding feedback on elementary school student's scientific knowledges, inquiry abilities and their perceptions of it. For this study, two classes of 5th grade elementary school in suburb were selected. As an experimental group, one class was selected to apply the lessons adopting portfolio assessment regarding feedback, and the other class as a control group was selected to apply the lessons adopting portfolio assessment without feedback. The investigator taught and assessed both group students. The results showed a significant difference in scientific knowledge between the experimental group and the control group (p<.05). More detailed analysis of scientific knowledge found that the feedback effect was statistically positive in the memory and the understanding domain, but there was no effect in the application domain. No statistical difference was identified in inquiry abilities. The results of the questionnaire on the perceptions of portfolio assessment showed that students of the experimental group had higher positive responses on the 'perception about the effects of lesson' and on the 'perception in scientific attitudes' than the control group. However, the control group students had higher positive responses on the 'perception about self-evaluate of their own portfolio' and the 'perception about need of feedback' than the experimental group.

이 연구는 공공도서관 사서의 정보활용능력 수준에 대한 자기인식과 실제 평가를 통해 Big6모형을 기반으로 하여 공공도서관 사서의 정보활용능력 수준실태를 78명의 사서를 대상으로 실험하였다. 연구 결과, 정보요구 영역은 높게, 정보평가 영역에 대해서는 다른 영역보다 낮게 나타났지만 모든 영역에 대해서 평균이상으로 조사되어 사서들의 정보활용교육 필요성을 파악할 수 있었다. 특히 정보활용교육 경험여부에 대한 두 집단간의 차이는 정보이용 영역을 제외하고는 통계적으로 유의미하지 않음을 알 수 있었다.

The purpose of this study was to investigate the effects of teacher's mathematical belief and student's mathematical performance, sex on the perception of mathematics classroom quality. And this study also detailed the relation between self-directed learning attitude and perception of mathematics classroom quality. For this purpose, this study used 'Students Perception of Mathematics Classroom Quality(SPOCQ)' as an instrument. This instrument focuses on appeal, challenge, choice, meaningfulness, self-efficacy. The 430 5th and 6th grade elementary school students were included in sample. The results obtained in this research are as follows; First, there was a significant difference in the perception of mathematics classroom quality between positive mathematical belief teacher's group and negative mathematical belief teacher's group. So, teacher's mathematical belief influence on the students' perception of mathematics classroom quality. Second, there was a significant difference according to the student's mathematical performance and sex. The students of high mathematical performance usually had positive perception of mathematics classroom quality and the male students also had higher mean than female students. Third, there was positive correlation between self-directed learning attitude and perception of mathematics classroom quality.

This study sets out to examine training courses for newly government-employed librarian for developing training contents to learn their basic knowledge, and suggests development model about training contents' planning, designing and making-process. In addition, in order to evaluate cyber training contents it devises self-evaluating tool, conducts a reviewing of questionnaire and measure by Delphi method. The final content made under the cyber contents development model proposes the six areas and 28th trials. Feasibility assessment for the purpose of evaluating educational contents, based on 17 questions to measure the factor analysis results, it yields, it yields 4 factors having more than .40 variance. Though differences in perception depending on factors did not show statistical significance, the difference in the adequacy of questions results significantly lower in some of them.

The present study was carried out to evaluate the impacts of the qualities of dental medical services on service value, consumer satisfaction and consumer loyalty for 221 patients who visited 17 dental hospitals or clinics located in Busan and Ulsan using questionnaires and obtained the following conclusion. By gender, males had higher perceptions of para-language than females did in the qualities of the dental medical services, and by the level of education, college students and university graduates had higher perceptions of body language and physical appearance. Scores of service value, consumer satisfaction and customer loyalty were higher in males, college students and university graduates, and married patients, but those were not statistically significant. It turned out that the qualities of the dental medical services were correlated with service value, consumer satisfaction and consumer loyalty. As the perception of para-linguistic and verbal communication in the qualities of the medical services increased, service value increased; as the perception of verbal communication and physical appearance increased, consumer satisfaction increased; and as the perception of verbal communication, physical appearance and body language increased, consumer loyalty increased. To sum up the above findings, the qualities of dental medical services influence service value, consumer satisfaction and consumer loyalty, so in the future, it will be necessary to study quality dental medical services with which patients are satisfied.
