이 연구의 목적은 BUN 및 혈청 creatining, total protein, albumin과 glucose의 장기간에 걸친 개체 내 변이를 산정하여, 각각의 critical difference를 구성하는 것이다. 임상적으로 건강한 20마리의 개에서 일주일에 한번씩 총 8주간 채혈하여, 장기간에 걸친 개체 내 변이를 구하고, critical difference를 산출하였다. BUN은 9.01 mg/dl, 혈청 creatining은 0.52 mg/dl, total protein은 0.99 g/dl, albumin은 0.39 g/dl, glucose는 20.64 mg/dl로 critical difference가 산출되었다. 동일한 개에서 연속적으로 측정된 검사항목 치가 critical value보다 차이가 적으면, 이 차이는 생리적인 변화에 기인한다고 할 수 있으며, critical value보다 차이가 크면, 다른 요인, 즉 질병의 진행이나 다른 동반된 질병의 존재를 의미한다고 할 수 있다.

Purpose: This descriptive - comparison study was conducted to investigate the critical thinking disposition of senior nursing students in three types of nursing program. Method: The convenience sample was drawn from 472 nursing students. Instruments used in this study were made California Critical Thinking Disposition Inventory developed by Facione & Facione (1994). Data was analyzed by descriptive statistics, t-test, ANOVA, Scheffe test with SAS 6.12 program. Result: 1. The total mean score of critical thinking disposition was 279.06. Inquisitiveness was the highest with an mean score 45.50, while systematicity was the lowest with mean score of 36.15. There was a statistically significant difference in critical thinking disposition(F=14.36, p=.00)according to senior nursing students in three types of nursing programs. 2. There was a statistically significant difference in critical thinking disposition(F=5.53, p=.00) according to age, marital status(t=-3.15, p=.00), religion(F=3.26, p=.02) and critical thinking course taken previously(t=3.10, p=.00). Conclusion: There was a statistically significant difference in critical thinking disposition(F=14.36, p=.00) according to senior nursing students in three types of nursing program. There was a statistically significant difference in Critical thinking disposition according to age, marital status, religion, logic, philosophy, critical thinking course.

The purpose of this study is to develop and to test the program for the improvement of preservice teachers' critical thinking ability. The main research problems to achieve the purpose of research are as follows; first, is the program for the improvement of preservice teachers' critical thinking ability effective to improve the critical thinking skills of preservice teachers? Second, is the program for the improvement of preservice teachers' critical thinking ability effective to improve the critical thinking dispositions of preservice teachers? To evaluate the effect of the program, 30(15; experimental group: 15; control group) sophomores were selected in Pusan. The conclusions of this research are as follows; first, there is a significant difference between experimental group and control group for critical thinking skills test. Second, there is no significant difference between experimental group and control group for critical thinking dispositions test.

Purpose: The descriptive-correlational study was undertaken in order to investigate the relationships between critical thinking disposition and critical thinking skill in clinical nurses. Methods: A convenience sample of 50 registered nurses was obtained from E University Hospital. The instruments used in this study were general characteristics, California Critical Thinking Disposition Inventory (CCTDI) and California Critical Thinking Skill Test(CCTST) developed by Facione & Facione (1994). The data were analyzed by descriptive statistics, t-test, ANOVA, Duncan test and Pearson's Correlation Coefficient with SPSS 12.0 Program. Results: 1) There was a statistically significant difference in critical thinking disposition according to age (F=3.23, p=.03) and educational background (F=39.07, p=.00). 2) There was a statistically significant difference in critical thinking skill according to age (F=3.40, p=.02), educational background(F=32.51, p=.00), and period of professional nursing experience(F=3.56, p=.02). Conclusion: A significant positive correlation between critical thinking disposition and critical thinking skill was found(r=.68, p=.00). Critical thinking disposition and critical thinking skill according to age and educational background had statistically significant differences. Therefore, it is needed to emphasize the necessity of continuous education and training of nurses which prepare their critical thinking ability.

본 연구는 대학생의 융복합 능력 함양을 위한 비판적 사고력과 사고성향을 파악하고 관계를 조사하는 연구이다. Park(1999)이 개발한 비판적 사고력과 사고성향 측정도구를 이용하여 2012년 11월 5일부터 2012년 11월 16일까지 자료 수집을 실시하였다. 대학생의 비판적 사고력은 성적과 문제중심학습 수강유무와는 통계적으로 유의한 차이를 보이지 않았지만, 학년별 통계적으로 유의한 차이가 있었으며(4학년이 다른 학년들보다 비판적 사고력이 높다), 비판적 사고 과목과 임상실습 수강 유무에 따라 통계적으로 유의한 차이가 있었다. 대학생의 비판적 사고성향은 어떠한 변수에 따라서도 유의한 차이가 없었다. 또한 대학생의 비판적 사고력과 사고성향의 상관관계를 살펴 본 결과 상관계수는 유의하였으나, 그 값이 너무 작았다. 그러므로 비판적 사고 관련 교육과 평가, 또는 연구 시 두 부분 즉, 비판적 사고력과 사고성향은 분리하여 다루어져야 한다.

The purpose of this study was to examine the relationship between critical thinking and academic achievement. Subjects were 396 junior and 371 senior high school students in Busan. The instruments used in this study were Cornell Critical Thinking Test and Academic Achievement Test. The results were as follows : First, there was a sinificant grade level difference in critical thinking. Second, there was a signficant sex difference in critical thinking and there was a significant interaction effect by grade level and sex. Third, critical thinking was significantly related to the students' academic achievement. The implications were discussed and recommendations for future research were made.

Theoretical equation to calculate thermal fatigue life was derived in which slow crack growth theory was adopted. The equation is function of crack growth exponent n. Cyclic thermal fatigue tests were performed at temperature difference of 175, 187 and 200$^{\circ}C$ respectively. At each temperature difference critical thermal fatigue life cycles of the alumina ceramics were 180,37 and 7 cycles. And theoretical thermal fatigue life cycles were calculated as 172, 35 and 7 cycles at the same temperature difference conditions. Therefore thermal fatigue behavior of alumina ceramics can be represented by derived equation. Also theoretical single cycle critical thermal shock temperature difference can be calculated by this equation and the result was consistent with the experimental result well.

공업용 세라믹은 자체의 특이한 물리적 특성으로 인하여 극한의 열 및 화학적 환경에서도 적용할 수 있는 우수한 고온 재료이다. 세라믹은 고온에서 저온으로 빠르게 이동되면 열충격을 받는다. 본 연구에서는 열충격에 대한 매개변수로 임계온도차이를 제안한다. 세라믹 부품에 대한 임계온도차이는 부품 크기와 대류열전달계수 등에 의해 영향을 받는다. 부품의 열충격 특성은 비정상 열응력에 의해 평가된다. 비정상 열응력이 파단계수를 초과한다면 열충격 균열이 표면에서 시작된다고 가정할 수 있다. 물에 대한 임계온도차이는 공기에 대한 임계온도차이보다 적다. 본 연구에서 사용된 국내 승용차용 삼원 촉매 담체는 반경 및 축방향 온도차이가 임계온도차이 아래에 존재하므로 충분한 열충격 성능을 가지고 있었다.

Method: A convenience sample of 221 registered nurses were obtained from one hospital in Seoul. The data were analyzed by descriptive statistics, t-test, ANOVA, Scheffe' test, Pearson correlation coefficient using SPSS WIN 14.0 program. Results: There were a statistically significant difference in the critical thinking disposition according to age, marital status, career length, and department. There were a statistically significant difference in professional nursing competence according to role, age, career length, current position, and department. There were a statistically significant difference in job satisfaction according to age, marital status, career length, and department. A significant positive correlation between critical thinking disposition and professional nursing competence, and job satisfaction was found. Conclusion: Critical thinking disposition, professional nursing competence and job satisfaction of clinical nurses are significantly related.
