Geoje copper ore deposits are fissure filled copper veins which developed in late Cretaceous pyroclastics, andesite and shale. Mineral paragenesis reveals a division of the hydrothermal mineralization into three stages: Stage I, deposition of pyrite, magnetite, specularite, quartz and chlorite; Stage II, deposition of chalcopyrite, sphalerite, galena, tetrahedrite, aikinite, cosalite, electrum, quartz and chlorite; Stage III, deposition of barren calcite. Filling temperatures of fluid inclusions in quartz of stage I range from 171 to $282^{\circ}C$ whereas fluid inclusions in quartz and sphalerite of stage II range from 213 to $262^{\circ}C$ and from 186 to $301^{\circ}C$ respectively. Salinities of fluid inclusions in quartz of stage I range from 5.2 to 11.2 weight percent equivalent to NaCl. Salinities of fluid inclusions in quartz and sphalerite of stage II range from 6.6 to 10.9 and from 7.1 to 14.4 weight percent equivalent NaCl. Salinities of ore fluid during major mineralization stage in this deposits reveal nearly the same ranges as those of many copper deposits in Koseong copper mining district which located about 30km apart from Geoje mine. But filling temperatures of fluid inclusions formed during major copper mineralization stage in this deposits show slightly lower than those of copper deposits in Koseong copper mining district.

Students` journals in science class are supposed to contribute to students` science learning and to provide plentiful information on students` learning and progress. If interaction could be reinforced in the process of writing journals, the positive effects of the journals are expected to be increased. New approaches in teaching should be supported by school and community. Otherwise, teachers are frequently frustrated and failed to introduce new ways of instruction into science classes. The purposes of the study are to develop interactive journals, and approaches to introduce interactive journals at school level. The status and situation of the school were investigated by survey. Interactive journals were developed by teachers who experienced workshops on developing journals. A model journal was provided as a guidance to teachers. To establish environments for introducing journals in the school, an invited lecture was provided to increase parents` perceptions on journals. A communication system among students, parents, and teachers was establishd, and educational materials, such as encyclopedia, books, computers, and so on were prepared. For efficient administration of journals, various prizes and events were established. As a result of the study, teachers participated experienced professional development in terms of journals, interactive journals for science class were developed, the environments for the introduction of interactive journals at school level were established, and most students successfully completed science journals.

Purpose: Accurate evaluation of metastatic cervical lymph nodes plays a decisive role in the treatment and prognosis of patients with squamous cell carcinoma of the head and neck. The purpose of this study is to investigate the usefulness of FDG-PET for diagnosis of cervical metastasis in the head and neck cancer by comparing with the conventional imaging study. Materials and Methods: The subjects on this study were 30 patients (24 males and 6 females, aged 39 to 76, mean 57.1) diagnosed as pathologic-proven squamous cell carcinomas of the head and neck. All patients underwent preoperative FDG-PET, CT(n=27) or MRI (n=3). Their medical records were reviewed retrospectively. Using pathologic reports as a golden standard, the results of FDG-PET were compared with conventional imaging study (CT/MRI) in the evaluation of cervical metastasis. Results: Thirty patients had five different primary sites which were tongue (11), supraglottis (10), glottis (6), hypopharynx (2) and tonsil (1). A total of 40 neck dissections were performed unilaterally in 20 patients and bilaterally in 10 patients. Of these, 16 showed pathologically positive for lymph node metastasis. The sensitivity and specificity of FDG-PET for the diagnosis of cervical metastasis was 75% and 100% respectively, compared with conventional imaging of 56.3% and 95.8%, respectively. The difference of sensitivity was not statistically significant (p=0.453). Of 5 cases with small metastatic node (<1cm), 3 were detected on PET detected correctly but none were detected by CT. Conclusion : FDG-PET was more accurate than conventional imaging study in the diagnosis of metastatic lymph nodes in squamous cell carcinomas of the head and neck, especially detection of small metastatic node. FDG-PET might be useful adjunct to conventional image in the preoperative evaluation of head and neck squamous cell carcinoma.

교사 연수와 수업 전문성 발달

김찬종(Kim, Chan-Jong) 서울대학교 교육종합연구원 2009 교육연구와 실천 Vol.75 No.-

교사의 수업 전문성에 대한 관심이 커지고 있다. 수업 전문성은 양성과정에서 시작하여 교사의 전 생애를 통해서 발달되고 변화된다. 교사 연수나 전문성 신장 프로그램 참여 경험은 이의 발달을 위한 좋은 계기나 자극이 되기도 한다. 이 연구에서는 교사의 수업 전문성에 대한 연구 성과를 통하여 수업 전문성의 특성과 발달, 그리고 교사연수의 영향에 대해서 알아보는 것이다. 수업전문성에 대한 이해는 과정-결과 모형과 같은 학생의 성취에 영향을 주는 특정한 기능이나 성향 파악에서 보다 복합적인 PCK, 실천적 지식 등으로 확장되어 왔다. 교사는 생애 주기별로 독특하고 특정한 발달 단계를 겪는다. 이는 개인의 지향과 특성 그리고 근무 상황에 따라 달라지며 우리나라 교사들은 전문적인 발달보다는 현장 적응적인 특성과 경험과 시행착오를 통한 제한적인 발달을 한다. 교사의 수업 전문성 발달에서 결정적 경험과 반성이 매우 중요한 역할을 하므로 이를 제공하는 것이 중요하다. 또한 교사들은 매일 매일의 수업을 실행하면서 실천적 반성을 통해서 지속적인 변화를 겪는다. 교사들의 수업전문성 향상을 위해서는 연수에 대한 부정적인 인식 극복, 수업 전문성에 대한 연구 성과를 활용한 교사 재교육 실행, 교사의 자발적 연구 모임 활성화, 학교의 발전과 교사의 전문성 신장을 연계, 교사들이 발달 단계에 적합한 연수 프로그램을 제공, 현장의 필요와 교사의 요구를 기반으로 한 발달 기회를 제공해야 한다. professional teaching ability receives more attention than ever. It is developing and changing throughout teachers entire career, beginning from the teacher education college. Attending in-service education or professional development workshop may provide effective opportunity or stimulus. By summarizing research on teachers professional teaching ability, the characteristics and development of professional teaching ability and the effects of in-service education on this are explored. Professional teaching ability had been understood based on process-product model. Recently, more comprehensive approach, such as PCK, practical knowledge have been developed. Teachers experience unique developmental process throughout career. It depends on personal orientations characteristics and working context. Korean teachers develop by adaptation and trial-and-error. In professional teaching ability development, critical experience or incidents play important role. It is important to provide such experience to teachers. Teachers also develop and experience continuous change from reflection-in-action in everyday teaching. For developing professional teaching ability, overcoming negative perception of teachers on in-service education, developing and administrating professional development program based on research, activating teachers spontaneous study meetings, connecting school development and teachers professional development, providing professional development program appropriate to teachers developmental stage, and based on needs and demands of teachers.

좌측 하악골에 생긴 골육종(Osteosarcoma) 1예

김찬종(Chan Jong Kim),이재동(Jae dong Lee),남순열(Soon Yuhl Nam) 대한두경부종양학회 2003 대한두경부 종양학회지 Vol.19 No.2

Osteosarcoma is one of the most frequently occurring malignant bone tumor except for multiple myeloma. However, osteosarcoma of the mandible is rare and aggressive malignancy constituting about 5% to 13% of all cases of skeletal osteosarcoma. The authors experienced a case of osteosarcoma of the mandible in a 31-years old male patient. He visited our outpatient clinic with painless mass of the cheek. On the basis of the clinical and imaging findings, the differential diagnosis included giant cell tumor, histiocytosis and malignant bone tumor. In the first operation, the mass of the mandible was excised. Intraoperative microscopic examination of a frozen section did not yield a diagnosis: however, the final definitive histologic examination revealed osteoblastic osteosarcoma. After 15days, wide excision with hemimandibulectomy was completed followed by postoperative radiotherapy and chemotherapy. With our experience, we report the progression of diagnosis and management for mandibular osteosrcoma.
