본 연구에서는 우리나라 과학영재교육을 담당하는 교사들의 과학영재교육 교수방법 전문지식의 수준을 조사하는 데 목적을 두었다. 2005년 기준 전국 16개 시·도 교육청 산하 영재학급 및 영재교육원에서 과학영재교육을 담당하는 교사 수는 총1,883명으로 조사되었다. 이 가운데 531명(28.2%)의 과학영재교육 교사는 ‘과학영재교육 교사 교수방법 전문지식 측정도구(서혜애·박경희, 2005)’에 응답하였으며, 응답한 교사의 교수방법 전문지식 수준은 최종학력, 연수이수여부, 학교급에 따라 차이가 있는 것으로 나타났다. ‘과학지식 및 과학교육학 지식’과 ‘영재교육학 지식’은 영재교육 연수 이수 유무와 관련 없이 교사의 성별 및 최종학력에 따라 차이를 보였으며, ‘과학영재교육과정 지식’은 교사가 어떤 영재교육 연수를 이수했는지, 어떤 학교급을 지도하고 있는 지에 따라 차이가 있는 것으로 나타났다. ‘교사 전문성 계발 지식’은 학교급, 성별에 따라 차이를 보였다. 연구결과에 근거하여 다음과 같이 과학영재교육의 질을 제고하는 방향을 제안하였다. 첫째, 효과적 과학영재교육교사 연수를 개발하기 위해서는, 연수기관은 연수 대상 교사의 학교급에 따라 연수프로그램의 교육내용을 달리하여 구성해야 할 것이다. 둘째, 과학영재교육 교사 임용정책에서는 최종학력 조건을 강화하고 교사 전문성 계발의 동기 수준을 고려하는 것이 바람직할 것이다. The research aims to investigate the status of teacher's professional knowledge level of teaching the gifted in science. As of 2005, there were 1,883 teachers who teach at gifted educational institutions affiliated with sixteen provincial offices of educations in Korea. Research subjects include 531 out of 1,883 teachers (28.2%) and they responded to the 'Science Teacher Scale of Professional Knowledge for Teaching the Gifted' (Seo & Park, 2005). It was found that there were significant differences in the levels of science teachers' professional knowledge for teaching the gifted in terms of highest degrees earned, school level, completion of inservice training programs of gifted education, etc. It was also found that ‘subject matter content knowledge in science and pedagogical content knowledge in science’ and ‘general pedagogical knowledge in gifted education’ varied along teachers' gender and highest degrees earned. ‘Science curriculum knowledge in gifted education’ were varied along completion of inservice teacher training programs and school levels. In conclusion, in order to raise the quality of gifted education, first, host institutions of inservice teacher training programs of gifted education are recommended to provide program contents in consideration with different schools levels of participating teachers. Second, policy makers may strengthen requirements of highest degrees earned for employing teachers in gifted education.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

This study was performed to elucidate the influence on the plasma decursinol concentration after administration of combined decursin and Cnidii Rhizoma or decurisin and Bupleuri Radix extracts in comparison with single decursin admimistration. The identification of decursional isolated from Angelica gigas was carried out by GC/MS and the concentration of decursinol in the plasma after oral administration was determined by HPLC. The value of area under the plasma concentration (AUC) and the maximal concentration (Cmas) of decursinol after administration of methanol and ether Angelicae Gigantis Radix extract was higher than those of single decursin-treated group. It was also found that the AUC and the Cmax of decursional after combined administration with decursin and Cnidii Rhizoma were higher than those of decursin administration, whereas those of combined with decursin and Bupleuri Radix was lower. Moreover, the studies were performed with decursinol only or with combined decursinol and Cnidii Rhizoma/Bupleuri Radix, both of combined treatment increased the plasma decursinol concentrations compared with decursinol-treated group in rats. On the basis of these results, it is concluded that co-existing substances or co-administration with other drugs may influence the plasma levels of decurisinol after oral administration.

Steroid acne and pityrosporum folliculitis have similar clinical manifestations. So it was not casy to do differential diagnosis of these two diseases. We have tried to find out the different points between these diseases in clinical characteristics, positive rate of the malassezia spores, and their response to antifungal agents. We studied 21 patients with acneiform eruptions which were distinct from acne vulgaris. Patients were divided into two groups by steroid treatment history. Among 21 patients, 6 were administered steroid just before eruption and 15 were free from steroid within 6 months. We have examined malassezia spores with 10% KOH/Parker blue black ink mount from papules, pustules and comedones according to the patients skin lesions. The malassezia spores detected in 5 paticnts(83.3%) in the former and 9 patients(60%) in the latter. In malassezia folliculitis, the frequency of which showed above the (3+) score of malassezia spore under microscopy was higher than in steroid acne. Mean duration of the disease was 70.4 weeks in latter group, which was longer than 5.2 weeks of the former group. And there were some differences between two groups in the distribution of the lesions. Mean treatment duration was same in two groups (4 wks, 3.5 wks). Steroid acne patients would be treated better with antifungal agents than with acne regimens.

Purpose: The purpose of this study was to compare the effectiveness of a structured preoperative PCA education to that of the usual informal teaching provided by hospital staff in alleviating postoperative pain through more effective use of PCA therapy. Method: As an advanced research, the knowledge about the use of PCA therapy and the attitude about the use of the pain medicine were estimated, and then as a later research, the knowledge about the use of PCA therapy, the attitude about the use of the pain medicine, and the score of the pain were estimated. Result: The experimental group those who received structured preoperative PCA education had statistically significant higher knowledge regarding the use of PCA therapy, the attitude about the use of he pain medicine, and the score of the pain were estimated. Result: The experimental group those who received structured preoperative PCA education had statistically significant higher knowledge regarding the use of PCA therapy(p=0.026) and more positive attitudes toward using pain medicine(p=0.004). The experimental group those who received structured preoperative PCA education reported better pain control 4(p=0.002), 8(p=0.014) and 24 hours(p=0.018) after the operation. Conclusion: The structured preoperative PCA education increases the knowledge for the use of patient's PCA therapy and changes their attitude toward the use of the pain medicine positively and consequently enable the use of PCA therapy to be more effective and then finally reduced the patient's pain after the operation.

Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.

Some genetic variants of Amphihaploid, Hypoamphidiploid, Amphidiploid are regenerated from tissue culture in Allium wakegi. They were applied to investigate the effects of the chromosomal differences on the gene expression of some isozymes. The electrophoretic migration patterns of total proteins were different at the position of MW5×10^5 Dalton among the genetic variants. Three different isozymes were characterized from the migration patterns of isozymes in the discontinuous polyacrylamide gel electrophoresis. Alcohol dehydrogenase(ADH) appeared 3 bands in the gel electrophoresis corresponding to 3 isozymes, that is allozymes distributed as single isozyme in each individual. Isocitric acid dehydrogenase(ICDH) appeared 5 bands in the gel and corresponds to 5 isozymes as allozymes which distributed single isozyme in each individual. Phosphoglucoisomerase(PGI) appeared 8 bands in electrophoresis and to 8 isozymes which originated from 2 genes and distributed more than two isozumes in each individual. According to the isozume expression in the genetic variants of Allium wagegi, the amplification of chromosomal numbers can affect neither to increase the isozyme numbers and concentration nor to express heterogeneous types in the genetic variants.
