중학교 과학영재 담당교사의 수업을 관찰하여 Pedagogical Content Knowledge(PCK)의 요소 를 분석하고, 요소간의 관련성을 알아보았다. 연구 대상은 대도시 지역의 중학생 대상 영재교 육원에서 과학을 가르치는 교사 4명이었으며, 전공은 각각 물리, 화학, 생물, 지구과학이고 2 명은 전임교사, 2명은 겸임교사였다. 또한 전임교사들은 영재학생들만 가르쳤고, 겸임교사들 은 보통 일반학생들을 가르쳤고, 특별히 주 1회 영재학생들을 가르쳤다. 수업관찰, 반구조화 된 인터뷰를 실시하였으며, 문서자료를 수집하여 질적으로 분석하였다. 연구 결과, 과학영재 담당교사의 PCK 요소의 몇 가지 특징이 나타났다. 교사들의 과학교수지향은 PCK의 요소들 과 긴밀하게 상호작용하고 있었다. 교사들의 교육과정지식은 교사에 따라 상이했지만, 학습 유형의 선택은 교사의 영재 교육 및 수업의 목표와 관련되어 있었다. 또한 이러한 교육과정 지식은 학생에 대한 이해의 영향을 받았다. 교사들은 교육과정지식과 학생에 대한 이해에 따 라 수업에서 서로 다른 교수전략을 사용하고 있었다. 또한 PCK의 요소들의 관계는 밀접했으 며 방향성을 가지고 있었다. 이러한 연구결과를 바탕으로 PCK의 요소와 관계성을 설명하기 위해 사면체 모델을 제안했다. In this study, we analyzed the characteristics of Pedagogical Content knowledge(PCK)'s components through actual course of teachers of science gifted students in the middle school. For this study, four middle school science teachers of gifted students belonging to the gifted education professional organizations in a metropolis were selected, each of them was physics, chemistry, biology, and earth science teacher. Two of them were full-time teachers to teach only gifted students and two were part-time teachers who had taught general students in ordinary time and specially had taught the gifted students once a week. Qualitative data were collected through classroom observations, interviews, and documents. As a result, some unique characteristics of PCK's components were identified. The teachers' orientations to teaching science were closely correlated with PCK's components. The teachers' knowledges of science curriculum were different individually. But the decisions about type of teaching(acceleration or enrichment) were connected with the objectives of gifted education and lesson objectives. Also, the teachers' knowledges of science curriculum were influenced by the knowledge of students' understanding. Teachers used different instructional strategies according to the knowledge of science curriculum and the knowledge of students' understanding. We found that PCK's components were so closely connected and could show the direction of relationships among those PCK's components. We suggested teachers' PCK model which was named "Tetrahedron Model of PCK", to explain the characteristics and relationships of PCK's components.

Purpose: This study purposed to examine the disease-related knowledge level and compliance with mood health behavior in patients with myocardial infarction according to the atherosclerotic risk factors . Method: The subjects consisted of 72 patients with myocardial infarction and the data were collected by interviewing the subjects with questionnaires and reviewing their medical records from September. 15. 1999 to July 31, 2000. Data were analyzed using the SAS program. Results: 1) With regard to atherosclerotic risk factors: of the subjects, 91.7% lacked regular exercise, followed by smoking (61.1%). 2) The average knowledge score of the patients was 19.7 and the average compliance score was 53.9. 3) There were no significant differences in the total knowledge scores according to the patients' atherosclerotic risk factors. 4) Non-diabetics were significantly higher in knowledge scores on domain of risk factors than the diabetics. 5) The overweight patients were significantly higher in knowledge score on domain of nature of disease than the normal-weight patients. 6) The total compliance stores of the non-smokers were significantly higher than those of the smokers. 7) The total compliance scores of the patients who do regular exercise were significantly higher than those of the patients who forgo regular exercise. 8) The non-smokers were significantly higher in compliance scores on domain of diet than the smokers. 9) The diabetic patients were significantly higher in compliance scores on domain of smoking cessation than the non-diabetics. 10) Patients who do regular exercise were significantly higher in compliance scores on other domains than the patients who forgo regular exercise. Conclusion : According to the above findings, it can be concluded that intensive nursing care and education should be provided to patients who have atherosclerotic risk factors such as smoking. hypertension, diabetes mellitus, lack of exercise, over weight, or hypercholesterolemia to increase disease related knowledge level and to improve compliance with good health behavior.

The 3D-QSAR analysis with N-(2-benzophenyl)-L-tyrosine derivatives was conducted by Comparative Molecular Field Analysis(CoMFA) and Comparative Molecular Similarity Indices Analysis (CoMSIA). Two models yield the leave-one-out cross-validated correlation coefficient q² values of 0.62 and 0.56, and the conventional correlation coefficient r² values of 0.92 and 0.86, respectively. The achievement of higher q² and r² values of CoMFA model indicates the significance of correlation of steric and electrostatic fields with biological activities. The contour maps obtained from both CoMFA and CoMSIA studies were interpreted with respect to the binding site of the receptor. The quality of CoMSIA model is slightly lower than that of CoMFA in terms of q² and r² values. The models obtained from the present study can be useful for the development of new compounds with a more improved activity.

Fabry disease(FD) is an X-linked recessive lysosomal disorder caused by a deficiency of a-galactosidase A(a-Gal A), localized at Xq22. Besides onset of pain and paresthesias in the extremities, FD was diagnosed by absence of a-Gal A activity. In this experiment the a-Gal A activity of Korean FD patients was spectrometrically analysed using an artificial substate, 4-Mrthylumbellifery1-a-D-galactoside. As expected, no a-Gal A activity was detected in lymphocytes and lymphoblastoid cells from FD patients. To screen the mutation in their a-Gal A genes, we performed single strand conformation polymorphism(SSCP) and PCR-direct sequencing form seven a-Gal A exons. The nonsense mutation was identified both in classically affected hemyzygotes and a heterozygote. They showed the C to T transition at nucleotide number 11,002, resulting in a arginine-to-stop(R342X). This result will be applicable for pre- and neonatal detection of FD and to define the genotype/phenotype correlation.

To help the guidance of treatment method, prevention of halitosis, and oral hygiene management for halitosis patient or non-halitosis group for investigating the status in accordance with awareness of halitosis to improve the oral health for college students, the survey including ques- tionnaire was performed for 331 persons of students who is studying in the Gimcheon college located in the northern province of Kyeongsang-Do. As a conclusion, the following data are obtained. 1. For the question of "I am acknowledging the halitosis", the replying person were 123 persons (37.2%), including men-69 persons(20.8%), women-54 persons(16.3%), So, in case of the ratio of acknowledging the halitosis, men was higher than women. On the contrary, for the question of "I do not acknowledging the halitosis", men-68 persons (20.5%), women-140 persons(42.3%), So, in case of the ratio of non-ackowledging the halitosis, men was much higher than women. 2. For the question of "When did you acknowledge the halitosis at most in the whole day?", total of 127 persons(38.4%) said "as soon as get up" out of the 183 persons (55%) who acknowledging the halitosis. The remaining replies were followed in the order of "before breakfast", "after breakfast", and "before sleeping". 3. In the status of oral hygiene, it showed that the persons who acknowledge the halitosis acts positively the frequency of toothbrushing (more than twice a day), method of toothbrushing, and brushing the tongue than the persons who do not acknowledge the halitosis. 4. In the status of smoking habits, there was no increment according to the duration of smoking, but in the status of amount of smoking, the persons who smokes less than half carton a day were 20 (6.0%), half through one carton a day were 31 (9.4%). So, it showed that the amount of smoking is affected to the cause of halitosis. 5. The ordinary prevention methods for oral hygiene according to the awareness of halitosis were investigated in the order of toothbrushing/brushing the tongue (37.3%), chewing the gum (33%), and using the rinsing liquids (12.4%).
