  • 학생들의 산술 활동 (수의 사칙연산) 학습에 관한 연구 중 분수량을 포함한 나눗셈 문제의 해결을 위한 자연수 지식의 활용을 상세히 다룬 연구가 매우 부족한 실정이다. 교수실험이 연구방법으로 사용된 본 정성연구에서는, 일년간 행해진 교수실험 중 일부 자료의 분석을 바탕으로 다양한 포함제 분수나눗셈 상황을 해결하기 위해 어떻게 자연수 나눗셈의 기본이 되는 단위분할 도식을 수정, 구성해 나갈 수 있는지에 대한 가능한 발달 경로(나머지가 있는 단위분할 도식, 분수 단위분할 도식)를 제시하고 있다. 따라서 본 연구는 다른 수 체계(자연수, 분수)에서 같은 종류의 연산(나눗셈)에 대한 조작적 연결성을 고찰함으로써 현재 학생들이 가지고 있는 수 연산에 관한 분절적 이해를 올바르게 지도할 수 있는 방안을 제시한다.

  • In order to supply the reference data to define the quality of life of the rural agricultural elderly population in the simplified steps, the data were collected by personal visits to 232 elder people over 65 (89 males and 143 females) in Sunchang area. The survey was conducted with written questionnaires concerning the quality of life, health-related habits, basic physical functions and cognitive behavior. The prevalence of the degenerative diseases were assessed by anthropometric and biochemical determinations. The averaged overall quality of life represented by EQ-5D index with Nam's model was calculated to be $0.865{\pm}0.1509$, and the percentages of people below the average were 38% (low QOL group) and 62% (high QOL group) were found to be the above the average. Generally, the subjects with male gender, higher educational background, higher self-rated health status, higher social activities were belonged to the high QOL group. The high QOL group had higher scores of daily living activities KADL and IADL, and lower risks in cognitive functions K-MMSE and depression scale GDS. There was no statistically significant correlation between biochemical indexes of blood and cognitive function and EQ-5D scores when the results were adjusted for age and gender. There were significant differences in nutritional assessment determined by the MNA between the high and low QOL groups. The low QOL group showed inferior nutritional status. The rapidly measurable factors of the quality of life of rural elderly were turned out to be physical activity scores and the simplified nutritional status measurement.

  • Mathematics has been usually recognized as value-neutral and anti-ideological subject, and as a result, it has not dealt with environmental problems clearly. Also, it is not easy to find any environment-related contents in the 7th mathematics curriculum. However, because mathematics is also precious human products and essence, in any ways there is a need to reflect the social issues in the mathematics subject which speak for human mental activities. If this need is admitted to change the mathematics contents to the direction of social issues, environmental problems can stand out and be dealt in the mathematics education. Among the 6 domains in the 7th mathematics curriculum, the environmental problems can be dealt with in the domains of ‘numbers and operation’, ‘letters and formulas’, ‘regularity and function’, ‘chances and statistics’, ‘measurement’ except in the domain of ‘diagrams’. Also, the '문장제들' which takes up a considerable part of mathematics textbooks needs the authentic situation, and thus it will be possible to take environmental situations as mathematical materials. Furthermore, one of the 7th mathematics curriculum is that it suggested further study in each level of each domain, the representative pattern of which is the application of the mathemantics contents to the daily life. With this kind of mathematics further study contents, environmental problems can provide a variety of contents for the further study. From this viewpoint, it can be expected that the contents of environmental education will be increased in the mathematics subject. Under the recognition that the mathematics subject cannot be an exception in considering environmental problems, this study has studied some concrete plans and examples for how the mathematics textbooks based on the 7th educational curriculum can deal with environmental Problems.

  • Purpose: Advancing genetic knowledge for oncology nurses is especially important in Korea because physicians have launched to incorporate genetic risk assessment and genetic testing into their practice. The purpose of this paper was to identify the effect of the first academic cancer genetic risk assessment and counseling course for Korean nurses. Methods: Thirty-five nurses were recruited and educated from June 8 to 14, 2006 in Seoul, Korea. Two measurement tools were used: 'knowledge about the hereditary breast and ovarian cancer (HBOC)' and 'knowledge about the cancer genetics'. Results: Students' score of knowledge about HBOC at pre-education was $12.22{\pm}2.23$ and after education, it increased to $13.62{\pm}1.76$. This change was statistically significant (t=-3.253, p=.003). The score of knowledge about cancer genetics at pre-education was $11.31{\pm}3.44$, and after education it has increased to $16.17{\pm}1.94$. It also was statistically significant (t=-6.92, p=.000). Conclusion: This program was effective to be a starting point for establishing genetic educational planning for the oncology nurses in Korea. This academically-based course is recognized as valuable by oncology nurses. With this new knowledge, nurses can begin to expand their role in delivering comprehensive cancer care services in Korea.

  • 빠르게 발전하고 있는 정보화 시대에 맞춰 교육환경에서도 많은 발전과 영향이 있다. 이에 대표적으로 이러닝(E-Learning)이 있다. 그러나 이러닝은 직접적인 교류와 참여율이 낮아 집중을 유지하기가 어렵고, 교수자 또한 학습자의 집중 여부를 파악하는데 한계가 있다. 본 논문은 이러닝을 사용하는 학습자의 집중도를 사용자 눈 개폐와 정수리 인식을 통하여 집중도 측정할 수 있는 시스템을 개발하였다. 본 시스템은 눈과 정수리를 인식하여 집중도를 측정하고 지표화하여 교수자에게 제공한다. 눈과 정수리를 인식한 경우 이벤트가 발생하고 사용자의 반응 결과에 따라 집중도가 지표화된다. 시스템 검증을위해 실험집단과 통제집단으로 실험하였고 집중도 지표가 90% 이상의 정확도를 보였다.

  • Purpose: This study was attempted to investigate the demand, the recognition, and the attitude of general people on Natural Family Planning Method(NFP), and to provide basic data for a development of a program to establish a healthy sexual life. Method: This is a descriptive correlative study, collecting data by questionnaires. The subjects were 130 people of three urban areas from March 1 to April 15, 2004. The measurement tool used was about demand, recognition, and attitude to the natural birth control method. The data analysis was done by number, percent and T-test, Pearson's correlation coefficient, using SPSS program. Results: The recognition, attitude, and demand to natural birth control method was 3.01, 2.84 and 2.73 respectively. The higher recognition of correlation for natural family planning, the higher attitude(r=.864, p=.000) and demand(r= .525, p=.000) of correlation for natural family planning. It was confirmed that the study subjects almost produced self esteem and confidence recognizing at the idea of life and self value, and positively thought of need, recognition, and attitude of natural family planning method which could keep their own health management. Conclusion: As the result above, we suggest that an educational program should be developed, diffused and supported, and culturally formed by nation and social group to insist the benefit of conjugal relations in natural family planning as well as to support the knowledge deficit.

  • Clinical and epedemiologic studies of coronary heart disease(CHD)have from time to time over the last three decades found associations between prevalence of CHD and behavioral attributes and cigarette smoking. The main purpose of this study is reduced to major risk factor of coronary heart disease through prohibition of smoking and control of behavior pattern. The subjects consisted of 120 smokers and 90 non-smokers who were married men older than 30 years working in officers. The officers were surveyed by means of questionnaire September 26 through October 6, 1989. The Instruments used for this study was a self-administered measurement tool composed of 59 items was made through modifications of Jenkuns Activity Survery(JAS). The Data were analysed by SAS(Statistical Analsis System) program personal computer. The statistical technique used for this study were Frequency, x$^2$-test, t-test, ANOVA, Pearson Correlation Coefficient. The 15 items were chosen with items above 0.3 of the factor loading in the factor analysis. In the first factor analysis 19 factors were extracted and accounted for 86% of the total variance. However when the number of factors were limited to 3 in order to derive Jenkins classification, three factors were derived. There names are Job-Involvement, Speed & Impatience, Hard-Driving. Each of them includes 21 items, 21 and 9, respectively. The results of this study were as follow : 1. The score of the smoker group and non-smoker group in Job-Involvement(t=5.7147, p<0.0001), Speed & Impatience(t=4.6756, p<.0001), Hard-Driving(t=8.0822, p<.0001) and total type A behavior pattern showed statistically significant differences(t=8.1224, p<.0001). 2. The score of type A behavior pattern by number of cigarettes smoked daily were not statistically significant differences. 3. The score of type A behavior pattern by duration of smoking were not significant differences. It was concluded that the relationship between smokers and non - smokers of type A behavior pattern was statistically significant difference but number of cigarettes smoked daily and duration of smoking were not significant differences. Therefore this study is needed to adequate nursing intervention of type A behavior pattern in order to elevated to educational effect for prohibition of cigarette smoking.

  • Purpose: This study was performed to compare the inverted digital images and film-based images of dry pig mandibles to measure the periodontal bone defect depth. Materials and Methods: Forty 2-wall bone defects were made in the proximal region of the premolar in the dry pig mandibles. The digital and conventional radiographs were taken using a Schick sensor and Kodak F-speed intraoral film. Image manipulation (inversion) was performed using Adobe Photoshop 7.0 software. Four trained examiners made all of the radiographic measurements in millimeters a total of three times from the cementoenamel junction to the most apical extension of the bone loss with both types of images: inverted digital and film. The measurements were also made in dry mandibles using a periodontal probe and digital caliper. The Student's t-test was used to compare the depth measurements obtained from the two types of images and direct visual measurement in the dry mandibles. A significance level of 0.05 for a 95% confidence interval was used for each comparison. Results: There was a significant difference between depth measurements in the inverted digital images and direct visual measurements (p>|t|=0.0039), with means of 6.29 mm ($IC_{95%}$:6.04-6.54) and 6.79 mm ($IC_{95%}$:6.45-7.11), respectively. There was a non-significant difference between the film-based radiographs and direct visual measurements (p>|t|=0.4950), with means of 6.64mm($IC_{95%}$:6.40-6.89) and 6.79mm($IC_{95%}$:6.45-7.11), respectively. Conclusion: The periodontal bone defect measurements in the inverted digital images were inferior to film-based radiographs, underestimating the amount of bone loss.
