The purpose of this correlational study was to offer strategies for nursing intervention to improve compliance with prenatal care. This study was designed to investigate degree of tardiness, correlation between hardiness and compliance with prenatal care. In research, the characteristic of hardiness has 1 teen demonstrated in resolving stressful situaltions and in adapting to overcome physical and psycho-logical tension. pregnancy is normal crisis process. Therefore, it is necessary to investigate degree of hardiness in normal pregnant woman and I think that concept of hardiness is able to become a new, important concept for prenatal care imtervention. The subjects were 388 normal pregnant woman over five months, who were selected from five university hospitals and two health centers in Taegu. Data were obtained using a convenience sample technique. Data collection was done from March 6 to June 18, 1992. The instruments used for this study were the Health Related Hardiness Scale developed by Pollock(1984) and compliance with a prenatal care scale developed by the author on the basis of results of a literature review. Data were analyzed using the SAS program for t - test, ANOVA, Scheffe test, Pearson correlation and stepwise multiple regression. The results are as follows : 1. The scores on the hardiness scale ranged from 35 to 210 with mean of 88.89. 2. The scores on the compliance with prenatal care scale ranged from 28 to 140 with a mean of 111.49. 3. There were significant differences between hardiness and obstetrical characteristic factors, duration of pregnancy, frequency of pregnancy, frequency of abortion(P .05). 4. There were significant differences between compliance with prenatal care and general and obstetircal characteristic factors, education and frequency of pregnancy(P .05). 5. Correlations between hardiness and compliance with prenatal care were all negative and significant(r=-.2276~ -.2930, P .000). Challenge of hardiness components was the low est (r= -.2814). 6. Significant differences between hardiness and compliance with prenatal care by group were as follows : Group 1 was the high est, whereas Group 8 was the lowest(F=5.47, P .0000). 7. Factors influencing compliance with prenatal care were : 1) Challenge was the main variable and accounted for 7.92% of the total variance. 2) Education and frequency of pregnancy accounted for an additional 2.74% of the total variance. From the above findings, this study suggests the following : 1) Considering the lack of empirical support, the theroy of hardiness needs to be evaluated. 2) A valid, reliable and culturally appropriate instrument needs to be developed for Health Related Hardiness Scale. 3) There is a need for further study of hardiness in a broad variety of populations. 4) There is a need for comparative study correlation between hardiness and compliance with prenatal care in woman with normal and abnormal pregnancies

A learner's cognitive conflict with his /her existing conception is regarded to be one of the most important factors for a conceptual change. In this study, the effects of the conflict situation types on inducing students' cognitive conflicts in Newton's law were examined. The thirty-four students of 10th grade were selected from a rural high school based on the result of pre-test. The two different types of conflict situations among many possible types were used in this study. One type was using logical conflict situation and the other was demonstrating real conflict situation. The levels of cognitive conflict were measured by 4-point Likert scale by three interviewers. As the results, the demonstration method was more effective than the logical argument method. In case of the logical argument method, rather than showing scientific conceptions, suggesting another misconception was more effective to the students who have misconception. However, logical argument method was not effective to those who have scientfic conceptions. To the students who have unscientific conceptions, the demonstration method was very effective for inducing cognitive conflict. From the results of this study, demonstration method of teaching seems to be very effective for inducing students' cognitive conflict and overcoming their misconceptions on scientific concept.

The research aimed to compare science curriculum between Korea and Israel and find out characteristics of science curriculum in Israel at middle school level. The middle school 'science' of the 7th revised national curriculum in Korea and middle school 'science and technology' in Israel were compared. Among characteristics of the Israel curriculum of 'science and technology,' distinct ones are as follows: First, 'science and technology' was most highly emphasized with the largest number of time allotment among all subjects at middle school level in Israel. Second, the contents of 'science and technology' were classified into seven areas of 'energy and interaction', 'materials', 'organism', 'earth and the universe', 'technological systems and products' . 'information and communication',and 'ecosystems' rather than four areas of energy, materials, life and earth in Korea. Third, 'organism' was allocated with the highest number of hours among seven areas. Fourth, objectives of each content of 'science and technology' were divided into three categories: scientific aspect, technological aspect, and social value and objectives of each category were related to one another. This characteristic seems to stress STS, multidisciplinary, and interdisciplinary approaches in 'science and technology' in Israel. Such characteristics of the 'science and technology' education in Israel are likely to make significant contributions to establish human resources of highly developing science and technology including IT, BT, NT, ST in the future society. Reflecting upon the characteristics of 'science and technology' education in Israel, Korea might seek for ways to improve its national power based on science and technology through strengthening science and emphasizing science and technology contents among school curriculum.

The purpose of this study was to identify the underlying dimensions of push and pull motivators for Soraksan, Kayasan, Naejangsan, and Pukhansan national parks in mountain regions. This study also examined the nature and extent of the reciprocal relationship between the push and pull factors. The result showed that four dimensions were derived from 12 push items, which were cultural and natural experience, escape and rest, health, and socialization and novelty motivators. Three dimensions also were derived from 12 pull items, which were facilities and culture, nature, and accessibility. The push and pull dimensions were correlated and regressed against each other. Given the nature of relationship between the push and pull factors, facilities and culture pull factor was affected by the cultural and natural experience motivation. Nature pull factor had strongly associated with culture and nature, escape and rest, health, and socialization and novelty motivations. Finally, accessible attraction pull factor had a positive relationship with health motivator, however, had a negative with cultural and natural experiencing motivation.

The present study was conducted to investigate the effect of ${\beta}$-carotene on the antioxidant system of rats with diabetes. Forty Sprague Dawley rats were fed the AIN-76 control diet or the same diet supplemented with ${\beta}$-carotene (7.2 mg/kg diet) for 3 weeks, then diabetes was induced in half the rats by administering streptozotocin (45 mg/kg BW) into the femoral muscle. Diabetic and normal rats were fed the experimental diets for 2 more weeks. To investigate the effect of dietary ${\beta}$-carotene on diabetes, the activities of antioxidative enzymes and glutathione concentration were determined in normal and streptozotocin-induced diabetic rats. The plasma glucose levels in diabetic rats were not influenced by the dietary supplementation of ${\beta}$-carotene. Hepatic activities of catalase and superoxide dismutase in diabetic rats were significantly lower than those of control rats but ${\beta}$-carotene tended to induce these activities. Glutathione-S-transferase activity was not significantly different between experimental groups. Glucose-6-phosphatase activity was induced in diabetic rats, but dietary supplementation of ${\beta}$-carotene reduced this activity. The hepatic concentration of reduced glutathione in diabetic rats was lower than that of control rats, but dietary supplementation with ${\beta}$-carotene restored the content to some extent. These data suggest that diabetic rats are exposed to increased oxidative stress and that dietary supplementation with ${\beta}$-carotene may reduce its detrimental effects.

The purpose of this study was to examine the health promoting behavior of university students and its related factors. A self-administered questionnaire survey was carried out for 1,031(male, 477, female, 554) students from 7 universities in Taegu from March 10 to April 15 2000. Collected data were analyzed by the $X^2$-test, t-test, ANOV A and structural equation modeling analysis. The results of this study were as follows; Mean score of health promoting behavior of women was higher than mean score of men(p〈0.01). According to the subordinate fields, female students showed significantly higher scores in the fields of stress management, nutrition, personal relations and alcohol-cigarette(p〈0.05). And in male students, the only fields of exercise had meaningfully higher score(p〈0.01). The highest degree of performance was marked in alcohol-cigarette field in female, and interpersonal field in male. In Both male and female students, the lowest field was health responsibility. The mean score of health promoting behavior showed significant differences in intermediating factors such as age, health education and grade in male, and such as grade, pocket money for a month, taking health education, perceived body shape and gastrointestinal symptoms in female(p〈0.05). The mean score of health promoting behavior showed significant differences in cognitive-perceptual factors and cues to action such as perceived health status, perceived benefits, perceived barriers, and health concern of parents in both male and female(p〈0.05). By the results of structural equation modeling analysis in male students, the economic status, gastrointestinal symptoms and perceived body shape as lean had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). In female students, perceived body shape as lean and perceived body shape as fat had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade, pocket money and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). On the consideration of above findings, it is recommended that perceived health status and perceived benefits should be raised and perceived barriers should be lowered to increase health promoting behaviors, by means such as institutional approach which can enhance the primary prevention for a disease. In addition, the health policy for improving parents' concern about health as well as university students, through various ways such as health education, consulting, and health program, should be employed.
