The purpose of this study was to examine the pedagogical content knowledge (PCK) in physics involved in two-step physics teacher preparation: ndergraduate teacher preparation and professional development programs for teacher license advancement. For analysis, PCK was divided into eight areas, and the relative emphasis on each area during each step of initial teacher preparation programs was examined. Also, a sample of teachers, selected by the purposive sampling, were surveyed, of which three were interviewed about their perceptions of the relative emphasis on each area of PCK and their preferred emphasis. To examine the degree and ways teachers enacted their PCK, four teachers’ classroom teaching were observed over a series of lessons. The results showed that the teachers surveyed and interviewed in this study were satisfied with the degree of emphasis on PCK that they experienced during their licensure programs. However, there was an unbalanced emphases on different areas of PCK. Knowledge about physics and physics teaching methods were emphasized whereas knowledge of assessment, teaching orientation, and learning context were overlooked. This unbalanced emphasis was found to affect teaching practices in the classroom. Based on the findings of this study, a number of strategies for addressing overlooked areas of PCK and ways to improve the current physics teacher preparation programs. 이 연구는 중등물리교사 양성기간을 예비교사과정과 초임교사의 자격연수과정까지로 보고 그 과정에서중등 물리교사에게 PCK를 개발할 기회가 얼마나 제공되고 PCK가 교수 실천에서 얼마나 드러나는가를 알아보았다. 이를 위해 사범대학 물리교육 전공과정과 1급 정교사 자격연수 과정을 PCK 관련 영역의 비율과 PCK 구성요소로 분석하였다. 그리고 이 과정을 모두 이수한 교사를 대상으로 물리 교사양성과정에서 다루는 PCK 영역의 적정한 비율과 구성요소에 관한 설문과 면담을 실시하였고, 물리 교수실천에서 나타난 PCK를 분석하였다. 연구결과 중등물리교사 양성과정에서 PCK 비중은 교사가 적정 수준으로 간주하는 정도임이 드러났다. 그러나 PCK 과정에서 PCK 요소는 균형 있게 다루어지지 않음이 발견되었다. 물리 교과에 관한 지식, 물리 교수방법에 관한 지식은 강조된 반면, 물리 교수 지향, 물리 학습평가 및 학습맥락에 관한 지식은 거의 다루어지지 않았다. 이러한 점은 교수 실천에서 교사가 겪는 어려움으로 드러났다. 이 연구결과에 기초하여 균형 있는 PCK 개발을 위한 중등물리교사 양성과정 전략 및 개선점을 제시하였다.

The purpose of this paper is to develope a distance education that would be a courseware for a specific object, which can be available for student to learn the necessary knowledge or function, with no restriction of time or place, using WWW and Oracle DBMS. The distance education was designed in this paper consists of bulletin board, subject information, lecturing schedule, online instructions, questions and answers, submit and confirmation of reports, evaluation of lecturing, reference sites, chatting and discussion room, and data bank. The distance education coupled by WWW and database will change the educational form from one-direction to bi-direction between a teacher and the students. This can also provide a multimedia information to the students through WWW environment with convenient user interface. Those benefits made it possible to offer animated audio-visual materials and search for the information concerned through a hypertext technique. Besides, various kinds of informations were stored at database to increase an effectiveness in managing data. Since both teacher and students, are easy to add new information using the process of instruction to the database, the amount of the stored information in the distance education can be expanded effectively.

Recently, allergic diseases are very prevalent in Korea, resulting in physical and economic losses during the life. It is well-known that the principle therapy is identification, eradication, and desensitization of allergens. There are many allergic diagnostic tools for identification of specific-allergens. However, none of them is satisfied with its efficiency due to lack of validity. Recently MAST-CLA has been widely used in the allergic clinical fields because of its simplicity and simultaneous identification of allergens. This study was designed to determine the positivity of allergen-specific antibodies using MAST-CLA in patients with allergic diseases, and evaluate the efficacy for allergen detection, compared to results of skin prick test. During June 2000 - September 2001, 325 study subjects visited Soonchunhyang University Chunan Hospital for the evaluation of allergic problems. Among them, 289 subjects were diagnosed with allergic disease and included for the study. Thirty four subjects visited children's allergic unit were evaluated specific allergens using a skin prick test at the same time. Our result as follows; 1. The positive rates of allergen-specific antibodies and total IgE were 51.2% and 73.4%, retrospectively. 2. There was significant difference in positive rate in age group, showing highest in teen ages(73.6%), but insignificant difference in sex in allergen-specific antibodies. 3. The positive rate was 60.4% in allergic rhinitis, 51.3% in allergic dermatitis, 46.9% in bronchial asthma, and 39.1% in urticaria in order(P=0.073). 4. Significant difference in month or season was observed, with highest rate in April(78.1%) and May(72.1%). The highest season was in spring(62.7%), and then summer(52.8%), fall(50.3%), and winter(41.4%) in order (P=0.04). 5. The three highest allergen-specific antibodies were D. pteronyssinus(39.3%), D. farinae(38.3%), and house dust(24.3%) in Korean inhalant pannel, However, in food pannel types of allergen-specific antibody were different as D. farinae(18.5%), Alternaria(18.5%), house dust(17.3%). 6. There were significant agreements between MAST-CLA and Skin prick test (D. farianae Kappa=0.636;D. pteronyssinus Kappa=0.78, both P<0.001) In conclusion, MAST-CLA could detect allergen-specific antibodies in patients with allergic diseases as a simple and valid tool of screening of allergy. Especially, it could be a useful measure of multiple allergens simultaneously in children However, more detailed allergens and valid assay for unmeasured allergens should be identified for Korean-specific allergens.

We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group). Intervals from calving to first service (99.6 vs. 81.8 days) and to conception (160.3 vs. 131.8 days) were shorter in the RHHP group than in the pre-RHHP group. Secondly, we determined the effect of milk yield (305 days) on the occurrence of postpartum diseases, BCS changes, and reproductive performance in cows under RHHP, The occurrence of metritis and metabolic diseases were greater in the over-10,000 kg group than in the under-l0,000 kg group. The over-10,000 kg group lost more body condition than the under-10,000 kg group from calving to month 3 postpartum. Nevertheless, reproductive performance did not differ between the two groups. These results indicate that reproductive performance can be improved by the application of RHHP in high yielding dairy herds and that reproductive performance in the cows under RHHP are not affected by high milk yielding.

When using any of the aggregate production planning techniques mentioned in previous studies, it is generally assumed that the inputs of information are deterministic and easy to generate. However, the problem is more complex if the criteria and informations are expressed imprecisions. Therefore, it requires suitable method to deal with imprecisions. For select proper comparison method of fuzzy numbers in aggregate production planning with imprecise informations or criteria, this study use Dubois & Prade fuzzy number comparison method and Li-Lee fuzzy number comparison method among comparison methods fuzzy numbers. And then, proper method between two methods is selected. Also it is presented illustration.

Widespread use of BCG has not controlled tuberculosis, and more effective vaccines are clearly needed. Although chemotherapy will remain the mainstay of antituberculosis treatment, the use of adjunctive immunotherapeutic modalitites is attractive, particularly in persons with drug-resistant tuberculosis. Administration of IL-2 or IFN-γto tuberculosis patients enhance bacillary elimination. Cell-mediated immunity is the critical protective immune response in tuberculosis. Mycobacterial antigens are recognized by T cells and that elicit production of protective cytokines are potentially important vaccine antigens. The 30 kDa antigen is secreted in large quantities by growing mycobacteria. That antigen elicits greater proliferation in lymphocytes from healthy tuberculin reactors than healthy tuberculin nonreactors. In this study, the T lymphocyte proliferative responses to 30 kDa antigen from Mycobactrium tuberculosis H37Rv were examined by using tonsilar and peripheral blood lymphocytes from PPD(+) and PPD(-) tonsilectomized persons. When cultured with 30 kD antigen, tonsilar mononuclear leukocytes and T cells of PPD(+) demonstrated more ^3H-thymidine incorporation than PPD(-) persons (stimulation index was 2.5 and 1.9, 0.8 and 1.0, repectively). Peripheral blood mononuclear cells (PBMC) and peripheral blood T lymphocytes were shown the similar responses to this antigen. The combination of IL-2 and 30 kDa antigen elicited a significant proliferative responsiveness in tonsilar mononuclear leukocytes and T cells of PPD(+) persons (SI was 20 and 14.1). PBMC and peripheral blood T cells of PPD(+) persons were also shown a significant responsiveness, but PPD(-) persons did not show. These results demonstrate that the 30 kDa antigen and IL-2 have a synergistic stimulatory property in mycobacteria sensitizing lymphocytes.

Chronic neutrophilic leukemia(CNL) is a very rare myeloproliferative disease, characterized by sustained mature neutrophilic leukocytosis with granulocytic bone marrow infiltration, high NAP(neutrophilic alkaline phosphatase) score and absence of philadelphia chromosome, It is frequently accompanied by hepatosplenomegaly, elevated serum vitamin B_12 and uric acid level. For the diagnosis of CNL, the leukemoid reaction, especially secondary to neoplasia, infection and autoimmune diseases, should be excluded. Since Tuohy's first description in 1920, more than 50 cases fullfilling the above criteria have been reported worldwide, and 4 cases in Korea. Several authors have demonstrated the defect of intracellualr killing in the mature neutrophil and this finding correlates well with the very high incidence of fatal infection, The hemorrhagic diasthesis in CNL is caused by functional abnormality of the platelet. This disease has tendency to transform to blastic crisis and acute leukemia as in other myeloproliferative disease, but characteristically shows frequent coexistence with multiple myeloma. Until now , the therapeutic trials in CNL have been disappointing. Hydroxyrea and busulfan can control hyperleukocytosis. On the basis of functional defect in neutrophil, alpha-2b-interferon has been tried and several reports have demonstrated the clinical and functional effect of interferon on CNL. CNL is very rate hematologic disease and there are few report about general aspect of disorder. We report here a typical CNL case presenting with splenomegaly and leukocytosis with a review of the literature.
