(4th-year) at nine college of nursing in Seoul concerning their perception and Attitude toward the profession of nursing, motive for the necessity of learning, environment of study, attitude of study and particulars relevant with study performance, particulars of library, references and reading, assignments and particulars of the degree of confidence for the learning achievement. Through the survey of the above Particulars, the following results were obtained by classifying all subject matters and by analysing motive of the selection of their course, awarding or not awarding of scholarships. 1. General characteristics: it was revealed that 406 students (57.1%) were attending at the junior. while 305 students (42.9%) were taking the senior.

The major response was that they came to well comprehend the patients families. the lowest response was that they could apply what was learned at lecture-hall to practice. This response incidentally showed the distance the lecture-hall and practical study. In general items, students of the 4th grade showed more favorable response than students of the 3rd grade and there was a significant difference. 10. As to the perception and attitude toward profession according to the motive of selecting the nursing science : Those who selected the nursing voluntarily showed stronger conception than those who selected the nursing through indirect influence. However, there was no significant difference on this point. Only there was a remarkable difference in the reading of Code for Nurses. 11.

연구목적: 본 연구는 유색 및 백색 지르코니아 세라믹으로 제작된 코핑의 디자인에 따른 지르코니아 세라믹 코핑의 파절 하중과 변연 적합성을 평가한 것으로 그 결과를 임상에 응용하는데 도움을 주고자 하였다. 연구재료 및 방법: CAD/CAM system (Everset, KAVO Dental GmbH, Biberach, Germany)을 이용하여, 80개의 상악 제1 소구치 세라믹 코핑을 제작하되, 1그룹은 전체적으로 균일하게 0.3 mm로, 2그룹은 협면 0.3 mm 설면 0.6 mm, 3그룹은 전체 0.6 mm 균일하게, 4그룹은 협면 0.6 mm 설면 1.0 mm로 디자인하고, 유색 (I) 및 백색 (II) 지르코니아 코핑을 각 그룹당 10개가 되게 하였다. 소성직후와 조정 후 코핑의 변연 적합성을 Video Microscope System (sv-35, Sometech, Seoul, Korea)를 이용하여 100배율로 관찰하였고, 금속 주 모형에 코핑을 강화형 글래스아이오노머 시멘트로 합착 후 Universal Testing Machine (Instron 4467, Norwood, MA, USA)을 이용하여 파절 하중을 측정하여, one-way ANOVA test 를 시행하여 결과를 분석하였다. 결과: 1. CAD/CAM 지르코니아 코핑의 파절 하중은 1그룹, 2와 3그룹, 그리고 4그룹간에 유의성있는 차이를 보였으며 I4, II4의 파절 하중값이 가장 컸다. 2. 코핑의 디자인이 같고 색이 다른 그룹간의 비교에서는 전 그룹 모두 파절 하중값의 유의성은 없었다. 3. 소성 직후 변연 오차 측정값은 I2그룹을 제외한 전 그룹에서 협측 측정점에서 변연오차가 가장 큰 경향을 보였다. 4. 소성 직후 변연 오차 측정값은 I 그룹 지르코니아 그룹에서 그룹별 전체적인 변연적합도를 보았을 때 그룹간에 유의한 차이는 없었다 (P>.05). 5. 소성직후 변연 오차 측정값은 백색 지르코니아 그룹에서 그룹별 전체적인 변연 적합도를 보았을때 II1그룹의 변연 오차가 가장 컸다 (P<.05). 6. 소성직후 변연오차 측정값은 디자인이 같은 그룹의 유색, 백색 비교에서, I1와 II1그룹을 제외한 나머지 그룹에서 백색 지르코니아의 변연 적합도가 더 좋았다 (P<.05). 7. 내면 조정 후에는 색상화 및 지르코니아 코어 디자인에 따른 전 그룹간 변연 적합도의 차이는 없었다 (P>.05). 결론: 지르코니아 코핑 디자인과 색상화에 따른 변연 적합성은 소성 직후에는 다소 차이가 있었으나 내면 조정을 하면 임상 사용에는 무리가 없을 것으로 판단되었고, 파절강도 강화를 위해 코핑의 두께는 가급적 두꺼워야 하나, 가시면 (순면, 협면)의 심미성(반투명성)을 고려할 경우 가시면을 0.3 mm로 얇게 해도 파절 강도에 큰 영향을 주지 않는 것으로 사료되었다.
